        IN

--------------------------------------------------------------------------------

(1)     Represents the shares of Class A Common Stock of the Issuer into which
        the following interests may be converted: (a) 50,000 shares of Class B
        Common Stock of the Issuer held directly by Paul G. Allen, (b)
        106,685,298 Class A Common Membership Units of Charter Communications
        Holding Company, LLC ("Charter Holdco") held by Vulcan Cable III Inc.
        ("Vulcan") and (c) 217,585,246 Class A Common Membership Units of
        Charter Holdco held by Charter Investment, Inc. ("CII"). Each of Vulcan
        and CII has an exchange option with the Issuer giving it the right, at
        any time, to exchange its Class A Common Membership Units (the "Class B
        Common Stock Equivalents") for shares of Class B Common Stock of the
        Issuer on a one-for-one basis. Class B Common Stock of the Issuer is
        convertible at any time into Class A Common Stock of the Issuer on a
        one-for-one basis. Mr. Allen is the sole stockholder of Vulcan and owns
        96.8% of the outstanding capital stock of CII. Mr. Allen is therefore
        deemed to have beneficial ownership of all of the Class B Common Stock
        Equivalents held by Vulcan and CII. As the ultimate controlling person
        of both Vulcan and CII, he is also deemed to have sole voting power with
        respect to the Class B Common Stock Equivalents held by each entity.
        Each entity is deemed to share its respective voting power as the direct
        owner of the Class B Common Stock Equivalents with Mr. Allen because of
        Mr. Allen's controlling interest in such entity.

(2)     Mr. Allen has beneficial ownership of 59.4% of the Class A Common Stock
        assuming conversion of all Class B Common Stock and Class B Common Stock
        Equivalents. Each share of Class B Common Stock of the Issuer has the
        right to a number of votes determined by multiplying (i) ten, and (ii)
        the sum of (1) the total number of shares of Class B Common Stock
        outstanding, and (2) the aggregate number of outstanding Class B Common
        Stock Equivalents, and dividing the product by the total number of
        shares of Class B Common Stock outstanding. Therefore, assuming no
        conversion into Class A Common Stock of the Class B Common Stock and the
        Class B Common Stock Equivalents beneficially owned by Mr. Allen, Mr.
        Allen has beneficial ownership of Class B Common Stock with a voting
        power of 93.6% of the Issuer's outstanding Class A Common Stock

million in equity interests in InterLink Acquisition Partners, LLLP that Vulcan
had acquired concurrently with, and as part of, the acquisition of InterLink
Acquisition Partners, LLLP by Charter Holdco and one of its subsidiaries. Vulcan

        Registration Rights Agreement with CII, Vulcan and Mr. Allen

        On November 12, 1999, Mr. Allen, CII, Vulcan, Mr. Kent and the other
shareholders of CII entered into a Registration Rights Agreement (the
"Registration Rights Agreement"), which gives Mr. Allen, Vulcan and CII the
right to cause the Issuer to register the shares of Class A Common Stock issued
to them upon conversion of any shares of Class B Common Stock that they may
hold. The Registration Rights Agreement also gives Mr. Kent the right to cause
the Issuer to register the shares of Class A Common Stock issuable to him upon
exchange of membership units of Charter Holdco.

        The Registration Rights Agreement provides that Mr. Allen, Mr. Kent and
Vulcan are entitled to unlimited "piggyback" registration rights permitting them
to include their shares of Class A Common Stock in registration statements that
the Issuer files from time to time. These holders may also exercise their demand
rights, causing the Issuer, subject to specified limitations, to register their
Class A Common Stock, provided that the amount of shares subject to each demand
has a market value at least equal to $50 million (or, if the holders
participating in the offering own less than $50 million in the aggregate, then
the market value of all of their Class A Common Stock).

        Holders may elect to have their shares registered pursuant to a shelf
registration statement provided that at the time of the election, the Issuer is
eligible to file a registration statement on Form S-3 and the amount of shares
to be registered has a market value equal to at least $100.0 million on the date
of the election.

        Mr. Allen also has the right to cause the Issuer to file a shelf
registration statement in connection with the resale of shares of Class A Common
Stock then held by or issuable to specified sellers who have acquired or will
acquire Class A Common Stock or membership units of Charter Holdco in exchange
for their contribution of interests in Rifkin Acquisition Partners, L.L.L.P.,
InterLink Communications Partners, LLLP, Falcon Communications, L.P. and Bresnan
Communications Company Limited Partnership and who have the right to cause Mr.
Allen to purchase the equity interests issued to them as a result of the
acquisitions of these entities.

        The foregoing description of the Registration Rights Agreement is not,
and does not purport to be, complete and is qualified in its entirety by
reference to the Registration Rights Agreement, a form of which is filed as
Exhibit 10.6 hereto and incorporated in its entirety by reference.

guaranteed the redemption obligation of Charter Holdco.

                On November 12, 1999, Mr. Allen entered into two agreements with
certain recipients of Class A Preferred Units of Charter Holdco, each of whom

                The first of the two agreements (the "Rifkin Accretion Put
Agreement") gives the holder the right to sell to Mr. Allen any or all shares of
its Class A Common Stock at $19 per share (subject to adjustments for stock
splits, reorganizations and similar events), plus interest at a rate of 4.5% per
year, compounded annually. Subject to the occurrence of certain events (such as

specified period of time), the right terminates on November 12, 2001.

                The second of the two agreements (the "Rifkin Registration
Support Put Agreement") gives the holder the right to sell to Mr. Allen any or
all shares of its Class A Common Stock at the market price if at any time from
May 12, 2000 through November 12, 2001 (or earlier under certain circumstances),
the shares are not registered under the Securities Act of 1933.

                The Rifkin Accretion Put Agreements apply to an aggregate of
6,946,892 shares of Class A Common Stock. The Rifkin Registration Support Put
Agreements also apply to an aggregate of 6,946,892 shares of Class A Common
Stock.

any or all shares of its Class A Common Stock at $26.72 per share (subject to
adjustments for stock splits, reorganizations and similar events), plus interest
at a rate of 4.5% per year, compounded annually. Subject to the occurrence of

Communications Company Limited Partnership to Charter Holdco. The transaction
with the Bresnan holders will not be consummated prior to February 3, 2000.

                Each agreement will give the holder the right to sell to Mr.

per share (subject to adjustments for stock splits, reorganizations and similar
events) equal to the value attributable to each membership unit initially issued
to the Holder, plus interest at a rate of 4.5% per year, compounded annually.

        Stockholders' Agreement Among Jerald L. Kent, Paul G. Allen et al.

        On December 21, 1998, Mr. Allen, Mr. Kent and the other CII stockholders
entered into a Stockholders Agreement. Pursuant to the Stockholders Agreement,
Mr. Allen has a right of first refusal to purchase any CII common stock that a
party to the agreement proposes to sell to a third party (with certain estate
planning transfers excepted). Each CII stockholder, including Mr. Allen and Mr.
Kent, has the right to participate in any sale of another stockholder's common
stock if the sale would consist of at least 25% of the outstanding common stock
of CII. If Mr. Allen agrees to sell more than 50.1% of CII, Mr. Allen has the
right to compel the other CII stockholders, including Mr. Kent, to sell their
CII common shares, pro rata based on terms set forth in the Stockholders
Agreement. If Mr. Kent or another CII stockholder other than Mr. Allen dies,
becomes disabled or is terminated as an employee of CII, CII is obligated to
repurchase the stockholder's shares 



                                      -19-

<PAGE>   20

(and the stockholder or his estate is obligated to sell the shares) at fair
market value. CII's obligation to purchase the shares is guaranteed by Mr.
Allen. In addition, if CII engages in certain business combinations, the CII
stockholders, including Mr. Kent, have the right to compel Mr. Allen to purchase
their shares at fair market value. The Stockholders Agreement terminates upon
the effectiveness of a Registration Statement on Form S-1, registering CII's
common stock.

        The foregoing description of the Stockholders Agreement is not, and does
not purport to be, complete and is qualified in its entirety by reference to the

        Put Agreements with Jerald L. Kent, Barry L. Babcock and Howard L. Wood

        On November 12, 1999, Mr. Allen entered into a Put Agreement with each
of Jerald L. Kent, Barry L. Babcock and Howard L. Wood (the "Founder Put
Agreements"). Each of the Founder Put Agreements gives the holder the right to
sell his shares of common stock of CII to Mr. Allen at any time after May 12,
2000, at a price equal to the product of (a) the average trading price of a
share of Class A Common Stock of the Issuer over the thirty-day period preceding
the exercise of the put option, and (b) a fraction, the numerator of which is
the total number of membership units held by CII and the denominator of which is
the total number of outstanding shares of CII. The purchase price is subject to
adjustment in certain events (for example, if CII owns assets other than its
interest in Charter Holdco). The put agreement will terminate if Mr. Allen no
longer has voting control of CII (or sooner in certain circumstances).

        The foregoing description of the Founder Put Agreements is not, and does
not purport to be, complete and is qualified in its entirety by reference to the
form of Founder Put Agreement, a copy of which is filed as Exhibit 10.14 hereto

         (b) of the first sentence of this definition until the circumstances
         giving rise to such inability no longer exist. Any change in the ABR
         due to a change in the Prime Rate or the Federal Funds Effective Rate
         shall be effective as of the opening of business on the effective day

         such Person or (b) direct or cause the direction of the management and
         policies of such Person, whether by contract or otherwise.

         (taking into account all related current credits or current deductions)
         resulting from the receipt (actual or constructive) or accrual of such
         payments, be equal to the first of such payments. In making

         advisor.

                  "Approved Holder" shall mean each of the Borrower and any

         SECTION 2.1 Commitments. Subject to the terms and conditions hereof,
each Lender severally agrees to make a term loan (a "Loan") to the Borrower in
an amount not to exceed the amount of the Commitment of such Lender. Subject to
Section 2.9, the Loans shall be Eurodollar Loans.

         SECTION 2.2 Procedure for Loan Borrowing. The Borrower shall give the
Administrative Agent irrevocable written notice by 10:00 A.M., New York City
time, on the Effective Date requesting that the Lenders make each Lender's Loan
in a single drawing on the third Business Day thereafter (the "Funding Date")
and specifying the amount to be borrowed and the Interest Period with respect
thereto. Upon receipt of such notice the Administrative Agent shall promptly
notify each Lender thereof. Not later than 12:00 Noon, New York City time, on
the Funding Date, each Lender shall make available to the Administrative Agent
at the Payment Office an amount in immediately available funds equal to the Loan
to be made by such Lender. The Administrative Agent shall credit the account of
the Borrower on the books of such office of the Administrative Agent with the
aggregate of the amounts made available to the Administrative Agent by the
Lenders in immediately available funds.

         SECTION 2.3 Repayment of Loans; Evidence of Debt.

         (a) The Borrower hereby unconditionally promises to repay in Dollars
and in immediately available funds the outstanding principal amount of each
Lender's Loan in full on the Termination Date. The Borrower hereby further
agrees to pay interest in Dollars and in immediately available funds at the
Payment Office on the unpaid principal amount of each Lender's Loan from time to
time outstanding from the Funding Date until payment in full thereof at the
rates per annum, and on the dates, set forth in Section 2.7.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from the Loan of such Lender, including the amounts of principal and
interest payable and paid to such Lender from time to time under this Agreement.

         (c) The Administrative Agent shall maintain the Register pursuant to
Section 10.6(d), and a subaccount therein for each Lender, in which Register and
subaccounts (taken together) shall be recorded (i) the amount of the Loan made
hereunder, the Type thereof and each Interest Period applicable thereto, (ii)
the amount of any principal or interest due and payable or to become due and
payable from the Borrower to each Lender hereunder and (iii) both the amount of
any sum received by the Administrative Agent hereunder from the Borrower and
each Lender's share thereof.

         (d) The entries made in the Register and the accounts of each Lender
maintained pursuant to Section 2.3(b) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain the Register or
any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loan made to
the Borrower by such Lender in accordance with the terms of this Agreement.

         (e) Notwithstanding the foregoing, upon the request of any Lender made
through the Administrative Agent, the Loan made by each Lender may be evidenced
by one or more promissory notes, substantially in the form of Exhibit F (each, a
"Note"), instead of accounts. Each such Lender shall endorse on the schedules
annexed to its Note(s) the date, amount and maturity of the Loan made by it and
the amount of each payment of principal made by the Borrower with respect
thereto. Each such Lender is irrevocably authorized by the Borrower to endorse
its Note(s) and each Lender's record shall be conclusive absent manifest error;
provided, however, that the failure of a Lender to make, or an error in making,
a notation thereon with respect to its Loan shall not limit or otherwise affect
the obligations of the Borrower hereunder or under any other Loan Document, or
under any such Note to such Lender.

         SECTION 2.4  Prepayments; Collateral Releases.

         (a) The Borrower may, at any time and from time to time, prepay each
Lender's Loan, in whole or in part, without premium or penalty, (i) in the case

Business Days' irrevocable notice to the Administrative Agent, or (ii) in the
case of a prepayment of all or a part of an ABR Loan, upon at least one Business
Day's irrevocable notice to the Administrative Agent, in each case, specifying
the date and amount of prepayment and whether the prepayment is of Eurodollar
Loans, ABR Loans or a combination thereof, and, if of a combination thereof, the
amount allocable to each. Upon receipt of any such notice the Administrative
Agent shall promptly notify each Lender thereof. If any such notice is given,
the amount specified in such notice shall be due and payable on the date
specified therein, together with any amounts payable pursuant to Section 2.13.
Partial prepayments of Loans shall be in a minimum aggregate principal amount of
$10,000,000 or a whole multiple of $100,000 in excess thereof (or, if less, the

principal amount thereof).

         (c) If the Collateral Coverage Ratio shall be (i) [*] to 1.00 or less
for any period of five consecutive days or (ii) [*] to 1.00 or less on any day,
then, on the Business Day next succeeding the end of such period or such day, as

deliver to the Administrative Agent additional shares of

Coverage Ratio shall be at least equal to [*] to 1.00.

         (d) If the Collateral Coverage Ratio shall exceed [*] to 1.00 for any

the receipt of such notice by the Administrative Agent, the Administrative Agent
shall release Pledged Microsoft Stock (in amounts specified by the Borrower in a
written notice to the Administrative Agent) to the extent necessary such that,
after giving effect thereto, the Collateral Coverage Ratio shall be equal to or
greater than [*] to 1.00; provided however, that any such release of collateral
may not occur more than once during each calendar quarter.

         (e) In the event the Borrower, the Guarantor or any Affiliate of either
of them elects to exchange any Exchange Investment comprising of Class B Common
Stock of Charter Communications, Inc. into Class A Common Stock of Charter
Communications, Inc., the Borrower shall, at least five Business Days prior to
the date on which such Class A Common Stock is to be issued in such exchange,
prepay the entire principal amount of the Loans then outstanding together with
all accrued and unpaid interest thereon through the date of prepayment.

         SECTION 2.5 Continuation Options for Loans. Any Eurodollar Loans may be
continued in whole or in part as such upon the expiration of the then current
Interest Period with respect thereto by the Borrower giving notice to the
Administrative Agent, in accordance with the applicable provisions of the term
"Interest Period" set forth in Section 1.1, of the length of the next Interest
Period to be applicable to such Loan or portions thereof, provided that if the
Borrower fails to give such notice, any such Eurodollar Loans shall continue as
such for a new Interest Period of one month and provided, further that no
Eurodollar Loan may be continued as such after the date that is one month prior
to the Termination Date.

         SECTION 2.6 Minimum Amounts and Maximum Number of Tranches.
Notwithstanding anything to the contrary in this Agreement, all borrowings,
conversions, continuations and prepayments of Eurodollar Loans and all
selections of Interest Periods shall be in such amounts and be made pursuant to
such elections so that, after giving effect thereto, (a) the aggregate principal
amount of the Loans or portions thereof comprising each Eurodollar Tranche shall
be equal to $10,000,000 or a whole multiple of $100,000 in excess thereof and
(b) there shall be no more than 10 Eurodollar Tranches outstanding at any time.

Rate determined for such Interest Period plus the Applicable Margin.

         (b) Each ABR Loan shall bear interest at a rate per annum equal to the
ABR plus the Applicable Margin.

any interest payable thereon or (iii) any administrative or other fee or other
amount payable hereunder or under any fee arrangement with the Borrower and/or
the Guarantor shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such overdue amount shall bear interest at a rate
per annum which is (x) in the case of overdue principal, the rate that would
otherwise be applicable thereto pursuant to the foregoing provisions of this
Section 2.7 plus 2% or (y) in the case of any overdue interest, administrative
or other fee or other amount, equal to the Prime Rate plus 2%, in each case from
the date such non-payment first becomes due until such amount is paid in full
(whether before or after judgment).

         (d) Interest shall be payable in arrears on each Interest Payment Date,
each date of prepayment and the Termination Date; provided that interest
accruing pursuant to paragraph (c) of this Section 2.7 shall be payable from

         SECTION 2.8 Computation of Interest and Fees.

         (a) Fees and interest shall be calculated on the basis of a 360 day
year for the actual days elapsed. The Administrative Agent shall as soon as
practicable notify the Borrower and the Lenders of each determination of a
Eurodollar Rate in respect of any Eurodollar Tranche. Any change in the interest
rate on a Loan or portion thereof resulting from a change in the ABR shall
become effective as of the opening of business on the day on which such change
becomes effective. The Administrative Agent shall as soon as practicable notify
the Borrower and the Lenders of the effective date and the amount of each such
change in interest rate.

         (b) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to Section 2.7(a).

day of any Interest Period:

                  (a) The Administrative Agent shall have determined (which
         determination shall be conclusive and binding upon the Borrower) that,
         by reason of circumstances affecting the eurodollar market, adequate
         and reasonable means do not exist for ascertaining the Eurodollar Rate
         for such Interest Period, or

                  (b) The Administrative Agent shall have received notice from
         the Majority Lenders that the Eurodollar Rate determined or to be
         determined for such Interest Period will not adequately and fairly
         reflect the cost to such Lenders (as conclusively certified by such
         Lenders) of making or maintaining their affected Eurodollar Loans
         during such Interest Period, or

                  (c) Any Lender shall have determined (which determination
         shall be conclusive and binding upon the Borrower) at any time, that
         the making or continuance

         of any Eurodollar Loan has been made (x) unlawful by any law or
         governmental rule, regulation or order or (y) impossible by compliance
         by such Lender with any request by a Governmental Authority (whether or
         not having force of law), such Lender shall give written notice thereof
         to the Administrative Agent,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the Lenders as soon as practicable thereafter. If such notice is
given , in the case of the circumstances described in clauses (a) and (b) above,
the Eurodollar Loans of all Lenders, or, in the case of the circumstances
described in clause (c) above, the affected Lender's Eurodollar Loan, shall be
converted to ABR Loans. Until such notice has been withdrawn by the
Administrative Agent, no further Eurodollar Loans or portions thereof shall be
continued as such. If such a notice is withdrawn by the Administrative Agent,
the Agent shall give the Lenders written notice thereof and upon the third
Business Day thereafter each Lender's outstanding ABR Loan shall automatically
be converted into a Eurodollar Loan.

         SECTION 2.10  Pro Rata Treatment and Payments.

         (a) The borrowing by the Borrower from the Lenders hereunder on the
Funding Date shall be made pro rata according to the Exposure Percentages of the
relevant Lenders.

         (b) Each payment (including each prepayment) by the Borrower on account
of principal of and interest on each Lender's Loan shall be made pro rata
according to the respective outstanding principal amounts of each Lender's Loan
then held by the Lenders.

         (c) All payments (including prepayments) to be made by the Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 12:00 Noon,
New York City time, on the due date thereof to the Administrative Agent, for the
account of the Lenders (other than fees payable solely to the Administrative
Agent or the Agents), at the Payment Office, in Dollars and in immediately
available funds. Any payment received by the Administrative Agent after such
time shall be deemed to have been received on the next succeeding Business Day.
The Administrative Agent shall distribute to the Lenders such payments which are
payable to the Lenders promptly upon receipt in like funds as received. If any
payment hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day. If any payment on a Eurodollar Loan becomes
due and payable on a day other than a Business Day, the due date thereof shall
be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in which
event such payment shall be made on the immediately preceding Business Day. In
the case of any extension of any payment of principal pursuant to the preceding
two sentences, interest thereon shall be payable at the then applicable rate
during such extension.

         (d) Unless the Administrative Agent shall have been notified in writing
by any Lender prior to the Business Day preceding the Funding Date that such
Lender will not make the amount that would constitute its share of such
borrowing available to the Administrative Agent on the Funding Date, the
Administrative Agent may assume that such Lender is making such


                                      -18-

<PAGE>   24

amount available to the Administrative Agent, and the Administrative Agent may,
in reliance upon such assumption, make available to the Borrower a corresponding
amount. If such amount is not made available to the Administrative Agent by the
required time on the Borrowing Date therefor, such Lender shall pay to the
Administrative Agent, on demand, such amount with interest thereon at a rate
equal to the daily average Federal Funds Effective Rate for the period until
such Lender makes such amount immediately available to the Administrative Agent.
A certificate of the Administrative Agent submitted to any Lender with respect
to any amounts owing under this Section 2.10(d) shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
of such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
Eurodollar Loans hereunder, on demand, from the Borrower.

         (e) Unless the Administrative Agent shall have been notified in writing
by the Borrower prior to the date of any payment being made hereunder that the
Borrower will not make such payment to the Administrative Agent, the
Administrative Agent may assume that the Borrower is making such payment, and
the Administrative Agent may, but shall not be required to, in reliance upon
such assumption, make available to the Lenders their respective pro rata shares
of a corresponding amount. If such payment is not made to the Administrative
Agent by the Borrower within three Business Days of such required date, the
Administrative Agent shall be entitled to recover, on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such amount with interest thereon at the rate per annum equal to the daily
average Federal Funds Effective Rate. Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

         SECTION 2.11 Requirements of Law.

         (a) If the adoption of or any change in any Requirement of Law or in
the interpretation or application thereof or compliance by any Lender with any
request or directive (whether or not having the force of law) from any central
bank or other Governmental Authority, in each case made subsequent to the
Effective Date:

                  (i) shall subject any Lender to any tax of any kind whatsoever
         with respect to this Agreement or the Loan made by it or change the
         basis of taxation of payments to such Lender in respect thereof (except
         for Non-Excluded Taxes covered by Section 2.12 and changes in the rate
         of tax on the overall net income of such Lender);

                  (ii) shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         held by, deposits or other liabilities in or for the account of,
         advances, loans or other extensions of credit by, or any other
         acquisition of funds by, any office of such Lender which is not
         otherwise included in the determination of the Eurodollar Rate or is
         not otherwise paid by the Borrower pursuant to Section 2.11(c); or

                  (iii) shall impose on such Lender any other condition;


                                      -19-

<PAGE>   25

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, continuing or
maintaining its Eurodollar Loan or to reduce any amount receivable hereunder in
respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender, upon its demand, any additional amounts necessary to compensate such
Lender for such increased cost or reduced amount receivable. If any Lender
becomes entitled to claim any additional amounts pursuant to this Section
2.11(a), it shall promptly notify the Borrower, through the Administrative
Agent, of the event by reason of which it has become so entitled.

         (b) If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority, in each case made subsequent to the Effective Date, has the effect of
reducing the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, after submission by such Lender to the
Borrower (with a copy to the Administrative Agent) of a written request
therefor, the Borrower shall promptly pay to such Lender such additional amount
or amounts as will compensate such Lender for such reduction.

         (c) The Borrower agrees to pay to each Lender which requests
compensation under this Section 2.11(c) (by notice to the Borrower), on the last
day of each Interest Period with respect to the Eurodollar Loan or any portion
thereof made by such Lender, so long as such Lender may be required by the Board
or by any other Governmental Authority to maintain reserves against any other
category of liabilities which includes deposits by reference to which the
interest rate on Eurodollar Loans is determined as provided in this Agreement or
against any category or extensions of credit or other assets of such Lender
which includes its Eurodollar Loan, an additional amount (determined by such
Lender and notified to the Borrower with a copy to the Administrative Agent)
representing such Lender's calculation or, if an accurate calculation is
impracticable, reasonable estimate (using such reasonable means of allocation as
such Lender shall determine) of the actual costs, if any, incurred by such
Lender during such Interest Period as a result of the applicability of the
foregoing reserves to such Eurodollar Loan or portion thereof, which amount in
any event shall not exceed the product of the following for each day of such
Interest Period:

                  (i) the principal amount of the Eurodollar Loan or portion
         thereof, as the case may be, made by such Lender to which such Interest
         Period relates and outstanding on such day; and

                  (ii) the difference between (x) a fraction, the numerator of
         which is the Eurodollar Rate (expressed as a decimal) applicable to
         such Eurodollar Loan or portion thereof, and the denominator of which
         is one minus the maximum rate (expressed as a


                                      -20-

<PAGE>   26

         decimal) at which such reserve requirements are imposed by the Board or
         other Governmental Authority on such date, minus (y) such numerator;
         and

                  (iii) a fraction the numerator of which is one and the
         denominator of which is 360.

Any Lender which gives notice under this Section 2.11(c) shall promptly withdraw
such notice (by written notice of withdrawal given to the Administrative Agent
and the Borrower) in the event such Lender is no longer required to maintain
such reserves or the circumstances giving rise to such notice shall otherwise
cease to exist.

         (d) A certificate as to any additional amounts payable pursuant to this
Section 2.11 submitted by any Lender, with a copy to the Administrative Agent,
to the Borrower shall specify in reasonable detail the basis for the request for
compensation of such additional amounts and the method of computation thereof
and shall be conclusive in the absence of manifest error. The Borrower shall
(except as otherwise provided in Section 2.11(c)) pay each Lender the amount
shown as due on any such certificate delivered by it within 30 days after
receipt thereof. The obligations of the Borrower pursuant to this Section 2.11
shall survive the termination of this Agreement and the payment of each Lender's
Loan and all other amounts payable hereunder.

         (e) Promptly after any Lender has determined that it will make a
request for additional amounts pursuant to this Section 2.11, such Lender will
notify the Borrower thereof. Failure on the part of any Lender so to notify the
Borrower or to demand additional amounts with respect to any period shall not
constitute a waiver of such Lender's right to demand additional amounts with
respect to such period or any other period; provided that the Borrower shall not
be under any obligation to compensate any Lender with respect to increased costs
or reductions with respect to any period prior to the date (the "Cut-Off Date")
that is six months prior to such request if such Lender was aware on the Cut-Off
Date of all the circumstances giving rise to such increased costs or reductions
and of the fact that such circumstances would in fact result in such increased
costs or reduction and provided, further, that the limitation in the preceding
proviso shall not apply to any increased costs or reductions arising out of the
retroactive application of any Requirement of Law.

         SECTION 2.12  Taxes.

         (a) Except as otherwise required by law, all payments made by the
Borrower under this Agreement shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future income,
stamp or other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by any Governmental Authority. If any taxes, levies, imposts, duties, charges,
fees deductions or withholdings are required to be withheld from any amounts
payable to the Administrative Agent or any Lender (or Transferee) hereunder
other than, (i) in the case of taxes imposed by the U.S. federal government, any
such taxes imposed under law in effect on the date such Lender (or Transferee)
becomes a Lender (or a Transferee) hereunder, or (ii) net income taxes and
franchise taxes (imposed in lieu of net income taxes) imposed on the
Administrative Agent or any Lender (or Transferee) as a result of a present or
former connection between the


                                      -21-

<PAGE>   27

Administrative Agent or such Lender (or Transferee) and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from
the Administrative Agent or such Lender (or Transferee) having executed,
delivered or performed its obligations or received a payment under, or enforced,
this Agreement) (taxes not described in clauses (i) and (ii) shall be
"Non-Excluded Taxes"), the amounts so payable to the Administrative Agent or
such Lender (or Transferee) shall be increased to the extent necessary to yield
to the Administrative Agent or such Lender (or Transferee) (after payment of all
Non-Excluded Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Agreement on an After-Tax Basis.
Promptly upon any Non-Excluded Taxes becoming payable by the Borrower, the
Borrower shall send to the Administrative Agent for its own account or for the
account of such Lender (or Transferee), as the case may be, a certified copy of
an original official receipt received by the Borrower showing payment thereof.
If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate
taxing authority or fails to remit to the Administrative Agent the required
receipts or other required documentary evidence or fails to pay any amount
necessary so that each Lender and Transferee receives each payment hereunder
grossed up on an After-Tax Basis for any Non-Excluded Taxes (including any U.S.
federal withholding taxes included in such term), the Borrower shall indemnify,
on an After-Tax Basis, the Administrative Agent and the Lenders (and any
Transferees) for any incremental taxes, interest or penalties that may become
payable by the Administrative Agent or any Lender (or Transferee) as a result of
any such failure. The agreements in this Section 2.12 shall survive the
termination of this Agreement and the payment of each Lender's Loan and all
other amounts payable hereunder.

         (b) If any Lender (or Transferee) or the Administrative Agent, as
applicable, receives a refund of a tax for which a payment has been made by the
Borrower pursuant to this Section 2.12, which refund in the good faith judgment
of such Lender (or Transferee) or the Administrative Agent, as the case may be,
is attributable to such payment made by the Borrower, then such Lender (or
Transferee) or the Administrative Agent, as the case may be, shall reimburse the
Borrower (without interest, other than interest included in such refund) for
such amount as such Lender (or Transferee) or the Administrative Agent, as the
case may be, determines to be the proportion of the refund as will leave it,
after such reimbursement, in no better or worse position than it would have been
if the payment had not been required. Each Lender (or Transferee) and the
Administrative Agent, as the case may be, shall use good faith in determining
whether to make claim for any refund that it determines is available to it.
Neither any Lender (or Transferee) nor the Administrative Agent shall be
obligated to disclose any information regarding its tax affairs or computations
to any Person in connection with this paragraph (b) or any other provision of
this Section 2.12.

         (c) Each Lender (or Transferee) shall deliver to the Borrower and the
Administrative Agent (or, in the case of a Participant, to the Lender from which
the related participation shall have been purchased) (i) on the Effective Date
(or date of transfer), two copies of either U.S. Internal Revenue Service Form
1001, Form 4224, Form W-8, Form W-9 or any subsequent versions thereof or
successors thereto properly completed and duly executed by such Lender (or
Transferee) claiming complete exemption from U.S. federal withholding tax on all
payments by


                                      -22-

<PAGE>   28

the Borrower under this Agreement and the other Loan Documents or specifying the
level of withholding of U.S. federal income tax required as of the date such
forms are supplied and (ii) in the case of each Lender (or Transferee) that is
not a U.S. Person (as defined in Section 7701(a)(30) of the Code) on or before
the first interest payment date on or after January 1, 2001, two copies of
properly completed United States Internal Revenue Service Form W-8BEN or W-8ECI
(or other appropriate form) that complies with requirements of law in effect as
of January 1, 2001 for claiming an exemption from or reduction in the rate of
United States withholding tax and shall continue to maintain the validity of
such form or shall provide other appropriate forms for the purpose of
establishing an exemption from or reduction in the rate of United States
withholding tax by complying on an ongoing basis with any applicable law in
effect on and after January 1, 2001 unless such Lender (or Transferee) is unable
to do so due to a change in law after the date such Lender (or Transferee)
becomes a Lender (or Transferee) hereunder. The forms described in clause (i)
shall be delivered by each Lender (or Transferee) on or before the date of the
first interest payment to it following the date it becomes a Lender (or a
Transferee) hereunder (or, in the case of any Participant, on or before the date
such Participant purchases the related participation) and on or before the date
of the first interest payment to it following the date, if any, such Lender (or
Transferee) changes its applicable lending office by designating a different
lending office (a "New Lending Office"). In addition, each Lender (or
Transferee) shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Lender (or Transferee)
unless such Lender (or Transferee) is unable to do so due to a change in law
after the date such Lender (or Transferee) becomes a Lender (or Transferee)
hereunder in which case, such Lender or Transferee will notify the Borrower and
the Administrative Agent of such inability in lieu of delivering such forms.
Each Lender (or Transferee) shall also promptly notify the Borrower at any time
it determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the U.S. taxing authorities for such purpose) due to a change in its
circumstances and not due, inter alia, to a change in applicable law after the
date it became a Lender (or a Transferee) hereunder or due to a change in the
circumstances of the Borrower, the Guarantor or the use of proceeds of such
Lender's (or Transferee's) Loan. The failure of a Lender (or a Transferee) to
deliver any form pursuant to this Section 2.12(c) as a result of a change in law
after the date such Lender (or a Transferee) becomes a Lender (or a Transferee)
hereunder or as a result of a change in circumstances of the Borrower, the
Guarantor or the use of proceeds of such Lender's (or Transferee's) Loan shall
not constitute a failure to comply with this Section 2.12(c). If a Lender (or
Transferee) is unable to deliver any form pursuant to this Section 2.12(c), the
sole consequence of such failure shall be that the indemnity described in
Section 2.12(a) hereof shall not be available with respect to such Lender or
Transferee.

         (d) The parties agree, notwithstanding the foregoing, that the Borrower
shall be responsible pursuant to this Section 2.12 to indemnify, on an After Tax
Basis, any affected Lender or the Administrative Agent for any U.S. federal
withholding tax imposed, even if such tax is imposed under law as currently in
effect, if such tax is imposed pursuant to the conduit financing regulations set
forth in Treasury Regulations Section 1.881-3 due to any financing transaction
(as such term is defined in Treasury Regulations Section 1.881-3) (other than
the Loan) to which the Borrower, the Guarantor or any Affiliate of either is a
party.


                                      -23-

<PAGE>   29

         (e) Any Lender (or Transferee) claiming any indemnity payment or
additional amounts payable pursuant to this Section 2.12 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to file any
certificate or document reasonably requested in writing by the Borrower if the
making of such a filing would avoid the need for or reduce the amount of any
such indemnity payment or additional amounts that may thereafter accrue and
would not, in the sole determination of such Lender (or Transferee), be
otherwise disadvantageous to such Lender (or Transferee).

         (f) In the event that a Lender or Transferee delivers to the Borrower
and the Administrative Agent a form pursuant to paragraph (c) above that
indicates that U.S. federal taxes (other than Non-Excluded Taxes) must be
withheld on payments to such Lender or Transferee, then the Administrative Agent
shall thereupon withhold from each payment due to the affected Lender or
Transferee such U.S. federal withholding taxes at the rate indicated, timely
deposit such amounts with an authorized depository and make such reports,
filings and other reports in connection therewith at the times and in the manner
required by law.

         (g) In the event any taxes other than Non-Excluded Taxes are imposed on
and paid by the Borrower or the Administrative Agent (other than through
withholding from payments made to the affected Lender (or Transferee)), then the
affected Lender (or Transferee) shall reimburse the Borrower or the
Administrative Agent, as the case may be, for any payment of such taxes, and any
penalties, interest, and other amounts, plus interest equal to the Prime Rate
plus 2% from the date of payment of such amounts.

         SECTION 2.13 Indemnity. The Borrower agrees to indemnify each Lender
(or Transferee) and to hold each Lender (or Transferee) harmless from any loss
or expense which such Lender (or Transferee) may sustain or incur as a
consequence of (a) the conversion of any Eurodollar Loan or portion pursuant to
Section 2.9 hereof, (b) a default by the Borrower in the continuation of
Eurodollar Loans or portions thereof after the Borrower has given a notice
requesting the same in accordance with the provisions of this Agreement, (c) a
default by the Borrower in making any prepayment of Eurodollar Loans or portions
thereof after the Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (d) the making of a prepayment of Eurodollar
Loans or portions thereof on a day which is not the last day of an Interest
Period with respect thereto. Such indemnification may include an amount equal to
the excess, if any, of (i) the amount of interest which would have accrued on
the amount so prepaid, or not so converted or continued, for the period from the
date of such prepayment or of such failure to convert or continue to the last
day of such Interest Period (or the proposed Interest Period), in each case at
the applicable rate of interest for such Loans provided for herein (excluding
the Applicable Margin) over (ii) the amount of interest (as reasonably
determined by such Lender) which would have accrued to such Lender on such
amount by placing such amount on deposit for a comparable period with leading
banks in the interbank eurodollar market. The obligations contained in this
Section 2.13 shall survive the termination of this Agreement and the payment of
each Lender's Loan and all other amounts payable hereunder.

         SECTION 2.14 Change of Lending Office. Each Lender (or Transferee)
agrees that, upon the occurrence of any event giving rise to the operation of
Section 2.11 or 2.12 with respect


                                      -24-

<PAGE>   30

to such Lender (or Transferee), it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender (or
Transferee)) to designate another lending office for its Loan or portion thereof
affected by such event with the object of avoiding the consequences of such
event; provided, that such designation is made on terms that, in the sole
judgment of such Lender, cause such Lender and its lending office(s) to suffer
no material economic, legal or regulatory disadvantage, and provided, further,
that nothing in this Section 2.14 shall affect or postpone any of the
obligations of the Borrower or the rights of any Lender (or Transferee) pursuant
to Sections 2.11 and 2.12; and provided, further that Section 2.12(d) shall not
apply to any Lender (or Transferee) who designates a New Lending Office at the
request of the Borrower pursuant to this Section 2.14.

         SECTION 2.15 Replacement of Lenders under Certain Circumstances. The
Borrower shall be permitted to replace any Lender which (a) requests
reimbursement for amounts owing pursuant to Sections 2.11 or 2.12 or (b)
defaults in its obligation to make its Loan hereunder, with a replacement bank
or other financial institution; provided that (i) such replacement does not
conflict with any Requirement of Law, (ii) no Event of Default shall have
occurred and be continuing at the time of such replacement, (iii) the Borrower
shall repay (or the replacement bank or institution shall purchase, at par) the
Loan and other amounts owing to such replaced Lender prior to the date of
replacement, (iv) the Borrower shall be liable to such replaced Lender under
Section 2.13 if any Eurodollar Loan or portion thereof owing to such replaced
Lender shall be prepaid (or purchased) other than on the last day of the
Interest Period relating thereto, (v) the replacement bank or institution, if
not already a Lender, and the terms and conditions of such replacement, shall be
reasonably satisfactory to the Administrative Agent, (vi) the replaced Lender
shall be obligated to make such replacement in accordance with the provisions of
Section 10.6 (provided that the Borrower shall be obligated to pay the
registration and processing fee referred to therein), (vii) until such time as
such replacement shall be consummated, the Borrower shall pay all additional
amounts (if any) required pursuant to Sections 2.11 or 2.12, as the case may be,
and (viii) any such replacement shall not be deemed to be a waiver of any rights
which the Borrower, the Administrative Agent or any other Lender shall have
against the replaced Lender.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

         To induce the Administrative Agent and the Lenders to enter into this
Agreement and to make each Lender's Loan, each of the Guarantor and the Borrower
hereby represents and warrants to the Administrative Agent, the Agents and each
Lender as of the Effective Date, which representations and warranties shall
survive the execution and delivery of this Agreement, that:

         SECTION 3.1 Financial Condition.

         (a) The reviewed balance sheet of the Guarantor as at June 30, 1999, a
copy of which has heretofore been furnished to each Lender, is complete and
correct and presents fairly the


                                      -25-

<PAGE>   31

financial condition of the Guarantor at such date. The Guarantor did not have,
at the date of the balance sheet referred to above, any material Guarantee
Obligation, contingent liability or liability for taxes, or any long-term lease
or unusual forward or long-term commitment, including, without limitation, any
derivative product, interest rate or foreign currency swap or exchange
transaction, which is not reflected in the foregoing balance sheet or in the
notes thereto.

         (b) The Federal income tax returns of the Guarantor (form 1040 and
Schedules A through E thereto) for the 1997 tax year, copies of which have
heretofore been furnished to the Administrative Agent, are in the form in which
they were filed with the Internal Revenue Service. As of the Effective Date, (i)
such tax returns have not been amended, supplemented or otherwise modified by or
on behalf of the Guarantor and (ii) the Guarantor has received no notice from
the Internal Revenue Service of any threatened or actual adjustments thereto.
The Guarantor has not yet filed his Federal income tax return for the 1998 tax
year but has timely filed for an extension.

         (c) Prior to the Effective Date, the Borrower has not at any time held
any material assets other than the Pledged Microsoft Stock or incurred any
material liabilities or expenses.

         SECTION 3.2 Financial Statements.

         (a) The pro forma unaudited balance sheet of the Borrower included in
the Confidential Information Memorandum is complete and correct and presents
fairly the financial condition of the Borrower at the date of the Confidential
Information Memorandum. The Borrower did not have, at the date of the balance
sheets referred to above, any material Guarantee Obligation, contingent
liability or liability for taxes, or any long-term lease or unusual forward or
long-term commitment, including, without limitation, any derivative products,
interest rate or foreign currency swap or exchange transaction, which is not
reflected in the foregoing statement.

         (b) Except as reflected in the balance sheets delivered pursuant to
Sections 3.1(a) or 3.2(a), there are no liabilities or obligations with respect
to the Borrower or the Guarantor of any nature whatsoever (whether absolute,
accrued, contingent or otherwise and whether or not due) which, either
individually or in aggregate, would be material to the Borrower or the
Guarantor. Neither the Borrower nor the Guarantor know of any basis for the
assertion against the Borrower or the Guarantor of any liability or obligation
of any nature whatsoever that is not fully reflected in the documents delivered
pursuant to Sections 3.1(a) and 3.2(a) which, either individually or in the
aggregate, would reasonably be expected to be material to the Borrower or the
Guarantor.

         SECTION 3.3 No Material Adverse Effect. Since the date of the balance
sheet of the Guarantor referred to in Section 3.1(a) and since the date of the
balance sheet of the Borrower referred to in Section 3.2(a), there has been no
development, event or circumstance which has had or could reasonably be expected
to have a Material Adverse Effect on the Guarantor or the Borrower,
respectively.

         SECTION 3.4 Limited Liability Company Existence; Compliance with Law.
The Borrower (a) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its organization, (b) has the limited liability
company power and authority, and the


                                      -26-

<PAGE>   32

legal right, to own and operate its property and assets and to conduct the
business in which it is currently engaged and (c) is duly qualified as a foreign
entity and in good standing under the laws of each jurisdiction where such
qualification is required. Each of the Borrower and Guarantor is in compliance
with all Requirements of Law, except to the extent that the failure to comply
therewith could not, in the aggregate, reasonably be expected to have a Material
Adverse Effect.

         SECTION 3.5  Powers Authorization, Enforceable Obligations.

         (a) The Borrower has the limited liability company power and authority,
and the legal right, to execute, deliver and perform the Loan Documents to which
it is a party and the other documents and agreements executed and delivered
pursuant thereto and to grant the Liens to be granted by the Borrower pursuant
to the Stock Pledge Agreement, and has taken all necessary action to authorize
the execution, delivery and performance of this Agreement and the other Loan
Documents to which it is a party and the other documents and agreements executed
and delivered pursuant thereto. No consent or authorization of, filing with,
notice to or other act by or in respect of, any Governmental Authority or any
other Person is required in connection with the borrowings hereunder or with the
execution, delivery, performance, validity or enforceability of this Agreement
or the other Loan Documents.

         (b) The Guarantor has the legal right to make, deliver and perform each
Loan Document to which he is a party and to guarantee the Obligations pursuant
to Article VII, and has taken all necessary action to authorize the execution,
delivery and performance of this Agreement and the other Loan Documents to which
he is a party.

         (c) This Agreement has been, and each other Loan Document to which the
Borrower or the Guarantor is a party will be, duly executed and delivered on
behalf of each Loan Party thereto. This Agreement constitutes, and each other
Loan Document to which either Loan Party is a party when executed and delivered
will constitute, a legal, valid and binding obligation of each Loan Party
thereto, enforceable against each such Loan Party in accordance with its terms,
except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

         SECTION 3.6 No Legal Bar. The execution, delivery and performance of
the Loan Documents, the extensions of credit hereunder and the use of the
proceeds thereof and the grant of Liens pursuant to the Stock Pledge Agreement
will not (a) contravene any Requirement of Law, (b) conflict or be inconsistent
with or result in any breach of any terms, covenants, conditions or provisions
of, or constitute a default under any Contractual Obligation of any Loan Party
and will not result in, or require, the creation or imposition of any Lien on
any of its properties, assets or revenues pursuant to any such Requirement of
Law or Contractual Obligation (other than pursuant to the Stock Pledge
Agreement) or (c) violate any provision of the charter documents of the
Borrower.

         SECTION 3.7 No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of any Loan


                                      -27-

<PAGE>   33

Party, threatened by or against any Loan Party (a) with respect to any of the
Loan Documents or any of the transactions contemplated hereby or thereby, (b)
the Pledged Microsoft Stock or (c) which could reasonably be expected to have a
Material Adverse Effect.

         SECTION 3.8 No Default. Neither Loan Party is in default under or in
breach of any of its Contractual Obligations in any respect which could
reasonably be expected to have a Material Adverse Effect. No Default or Event of
Default has occurred and is continuing.

         SECTION 3.9 Ownership of Property; Liens. Each Loan Party has good
title to all of its material property and none of such property of the Borrower
is subject to any Lien except as permitted by Section 6.3. The Borrower owns,
beneficially and of record, all of the Pledged Microsoft Stock free of any and
all Liens or options in favor of, or claims of, any other Person, except the
security interest created by the Stock Pledge Agreement. The Borrower and, prior
to transfer by the Guarantor to the Borrower, the Guarantor, have successively
been the beneficial owners of the Capital Stock of Microsoft being pledged
pursuant to the Loan Documents for more than two years and more than two years
has elapsed since the Guarantor paid full consideration for such stock.

         SECTION 3.10 Taxes. Each Loan Party has filed or caused to be filed all
material tax returns which are required to be filed (or, in the case of the
Guarantor, has filed appropriate extensions of the time for filing such returns)
and has paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its property by any Governmental Authority
(other than any such taxes or assessments which are not required to be paid
pursuant to Section 5.3 hereof); no tax Lien has been filed, and, to the
knowledge of any Loan Party, no claim is being asserted, with respect to any
such tax, fee or other charge.

         SECTION 3.11 Accuracy of Information. Neither the Confidential
Information Memorandum (taken as a whole and as supplemented by the Borrower and
the Guarantor prior to the Effective Date) nor this Agreement, any other Loan
Document or any other document, certificate, writing, return or statement
furnished or to be furnished to the Administrative Agent or the Lenders or any
of them, by or on behalf of any Loan Party for use in connection with the
transactions contemplated by this Agreement or the other Loan Documents,
contained or will contain, as of the date such statement, information, document
or certificate was or is so furnished (or, in the case of the Confidential
Information Memorandum, as of the Effective Date) any untrue statement of a
material fact, or omitted or will omit a material fact necessary in order to
make the statements contained herein or therein not misleading. There is no fact
known to any Loan Party that could reasonably be expected to have a Material
Adverse Effect that has not been expressly disclosed herein, in the other Loan
Documents, in the Confidential Information Memorandum or in such other
documents, certificates and statements furnished to the Administrative Agent and
the Lenders for use in connection with the transactions contemplated hereby and
by the other Loan Documents.

         SECTION 3.12 Federal Regulations. No part of the proceeds of any Loans
will be used directly or indirectly for "buying" or "carrying" any "margin
stock" within the respective meanings of each of the quoted terms under
Regulation U of the Board as now and from time to


                                      -28-

<PAGE>   34

time hereafter in effect. If requested by any Lender or the Administrative
Agent, the Borrower will furnish to the Administrative Agent and each Lender a
statement to the foregoing effect in conformity with the requirements of FR Form
G-3 or FR Form U-1 referred to in said Regulation U.

         SECTION 3.13 ERISA. Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code. No termination of a Single Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has arisen, during such five-year
period, in either case that would have a Material Adverse Effect. The present
value of all accrued benefits under each Single Employer Plan (based on those
assumptions used to fund such Plans) did not, as of the last annual valuation
date prior to the date on which this representation is made or deemed made,
exceed the value of the assets of such Plan allocable to such accrued benefits
by a material amount. Neither the Guarantor nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan that has
resulted or could reasonably be expected to result in a material liability under
ERISA, and neither the Guarantor nor any Commonly Controlled Entity would become
subject to any material liability under ERISA if the Guarantor or any such
Commonly Controlled Entity were to withdraw completely from all Multiemployer
Plans as of the valuation date most closely preceding the date on which this
representation is made or deemed made. No such Multiemployer Plan is in
"reorganization" or "insolvent" (as such terms are defined in ERISA).

         SECTION 3.14 Ownership of the Borrower. The Guarantor or the Estate
owns, beneficially and of record, all of the issued and outstanding Capital
Stock of the Borrower. All capital contributions required to be paid by any
member of the Borrower have been fully paid. The Borrower does not have
outstanding any other securities including, but not limited to, any securities
convertible into or exchangeable for any Capital Stock or any outstanding rights
to subscribe for or to purchase, or any options or warrants for the purchase of,
or any agreements providing for the issuance (contingent or otherwise) of, or
any calls, commitments or claims of any character relating to its Capital Stock.

         SECTION 3.15 Investment Company Act; Other Regulations. No Loan Party
is an "investment company", or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended.
No Loan Party is subject to regulation under any Federal or State statute or
regulation (other than Regulation X of the Board) which limits its ability to
incur Indebtedness.

         SECTION 3.16  Subsidiaries. The Borrower has no Subsidiaries.

         SECTION 3.17  Purpose of Loans. The proceeds of the Loans shall be used
by the Borrower to make distributions to the Guarantor for purposes of funding
the Initial Investments. The proceeds of the Loans may also be used for other
general purposes. Notwithstanding this or any other provision of this Agreement,
the Borrower may transfer to the Guarantor all or any


                                      -29-

<PAGE>   35

portion of the proceeds of each Lender's Loan; provided, that the Guarantor
shall use any such proceeds transferred from the Borrower in a manner consistent
with the provisions of Section 3.12 and this Section 3.17.

         SECTION 3.18 Public Utility Holding Company Act. The Borrower is not a
"holding company," or a "subsidiary company" of a "holding company," or an
"affiliate" of a "holding company" or of a "subsidiary company" of a "holding
company" within the meaning of the Public Utility Holding Company Act of 1935,
as amended.

         SECTION 3.19 Business of the Borrower. The Borrower is not engaged in
any business or activity of any kind or is a party to any transaction,
Contractual Obligation, Guarantee Obligation or other undertaking which is not
expressly permitted by, or directly related to the transactions contemplated by,
the Loan Documents.

         SECTION 3.20 Residency of the Guarantor. The Guarantor is a resident of
the State of Washington.

                                   ARTICLE IV

         as any Lender may from time to time reasonably request.

         SECTION 5.3 Payment of Taxes; Obligations. Each Loan Party shall pay
and discharge all material taxes, assessments and governmental charges or levies
imposed upon such Loan Party or upon such Loan Party's income or profits, or
upon any properties or assets belonging to such Loan Party, prior to the date on

before maturity or before they become delinquent, as the case may be, all of
such Loan Party's other obligations of whatever nature, except, in each case,
where (a) the amount or validity thereof is currently being contested in good
faith by appropriate proceedings and, in the case of the Borrower only, reserves

to have a Material Adverse Effect.

         SECTION 5.4 Conduct of Business and Maintenance of Existence. The
Borrower shall preserve, renew and keep in full force and effect its existence

         or the taking of any other action by the PBGC, any Loan Party or any
         Commonly Controlled Entity or any Multiemployer Plan with respect to
         the withdrawal from or termination, reorganization or insolvency of any
         Plan.

Each notice pursuant to this Section 5.6 shall be accompanied by a statement of
a Responsible Representative of the relevant Loan Party setting forth details of
the occurrence referred to therein and stating what action such Loan Party
proposes to take with respect thereto.

                                   ARTICLE VII

                                    GUARANTEE

         SECTION 7.1  Guarantee.

         (a) In order to induce the Lenders to execute and deliver this
Agreement and to make each Lender's Loan hereunder, and in consideration
thereof, the Guarantor hereby unconditionally and irrevocably guarantees to the
Lenders the prompt and complete payment and performance when due (whether at the
stated maturity, by acceleration or otherwise) of the Obligations. The Guarantor
further agrees to pay any and all expenses (including, without limitation, all
reasonable fees and disbursements of counsel, including allocated costs of
internal counsel) which may be paid or incurred by the Administrative Agent, the
Agents or any Lender in enforcing, or obtaining advice of counsel in respect of,
any rights under this Article VII. Without limiting the generality of the
foregoing, the Guarantor's liability shall extend to all amounts that constitute
part of the Obligations and would be owed by the Borrower but for the fact that
they are unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Borrower or for any other
reason. This Guarantee shall remain in full force and effect until all the
Obligations have been paid in full.

         (b) No payment or payments made by the Guarantor or any other Person or
received or collected by the Administrative Agent, the Agents or any Lender from
the Guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application, at any time or from time to time, in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of the Guarantor hereunder who shall
remain obligated hereunder, notwithstanding any such payment or payments (other
than payments made by or received or collected from the Borrower or the
Guarantor in respect of the Obligations) until the date upon which the
Obligations have been paid in full and the Commitments have been terminated.

         SECTION 7.2 No Subrogation. Notwithstanding any payment or payments
made by the Guarantor hereunder, or any set-off or application of funds of the
Guarantor by the Administrative Agent, the Agents or any Lender, the Guarantor
shall not be entitled to be subrogated to any of the rights of the
Administrative Agent, the Agents or any Lender against the Borrower or against
any collateral security or guarantee or right of offset held by the
Administrative Agent, the Agents or any Lender for the payment of the
Obligations, nor shall the Guarantor seek or be entitled to seek any
contribution or reimbursement from the Borrower in


                                      -36-

<PAGE>   42

respect of payments made by the Guarantor hereunder, until the Obligations are
paid in full and the Commitments are terminated. If any amount shall be paid to
the Guarantor on account of such subrogation rights at any time when all of the
Obligations shall not have been paid in full, such amount shall be held by the
Guarantor in trust for the Administrative Agent, the Agents and the Lenders,
segregated from other funds of the Guarantor, and shall, forthwith upon receipt
by the Guarantor, be turned over to the Administrative Agent in the exact form
received by the Guarantor (duly endorsed by the Guarantor to the Administrative
Agent, if required), to be applied against the Obligations, whether matured or
unmatured, in such order as the Administrative Agent may determine.

         SECTION 7.3 Amendments, etc. The Guarantor shall remain obligated
hereunder notwithstanding that, without any reservation of rights against the
Guarantor, and without notice to or further assent by the Guarantor, any demand
for payment of any of the Obligations made by the Administrative Agent, the
Agents or any Lender may be rescinded by such party, and any of the Obligations
continued, and the Obligations, or the liability of any other party upon or for
any part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Administrative Agent, the Agents or any Lender,
and this Agreement, any other Loan Document and any other documents executed and
delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Administrative Agent (or the Majority
Lenders, as the case may be) may deem advisable from time to time, and any
collateral security, guarantee or right of offset at any time held by the
Administrative Agent, the Agents or any Lender for the payment of the
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Administrative Agent nor the Agents or any Lender shall have any obligation to
protect, secure, perfect or insure any Lien at any time held by it as security
for the Obligations or pursuant to this Article VII or any property subject
thereto. When making any demand hereunder against the Guarantor, the
Administrative Agent, the Agents or any Lender may, but shall be under no
obligation to, make a similar demand on the Borrower or any other guarantor, and
any failure by the Administrative Agent, the Agents or any Lender to make any
such demand or to collect any payments from the Borrower or any such other
guarantor or any release of the Borrower or such other guarantor shall not
relieve the Guarantor of any liability under this Article VII, and shall not
impair or affect the rights and remedies, express or implied, or as a matter of
law, of the Administrative Agent, the Agents or any Lender against the
Guarantor. For the purposes hereof "demand" shall include the commencement and
continuance of any legal proceedings.

         SECTION 7.4 Guarantee Absolute and Unconditional. The Guarantor hereby
waives any and all notice of the creation, renewal, extension or accrual of any
of the Obligations and notice of or proof of reliance by the Administrative
Agent, the Agents or any Lender upon the guarantee contained in this Article VII
or acceptance of the guarantee contained in this Article VII; the Obligations,
and any of them, shall conclusively be deemed to have been created, contracted
or incurred in reliance upon the guarantee contained in this Article VII; and
all dealings between the Borrower or the Guarantor, on the one hand, and the
Administrative Agent, the Agents and the Lenders, on the other, shall likewise
be conclusively presumed to have been had or consummated in reliance upon the
guarantee contained in this Article VII. The Guarantor


                                      -37-

<PAGE>   43

waives (to the extent permitted by law) diligence, presentment, protest, demand
for payment and notice of default or nonpayment to or upon the Borrower or the
Guarantor with respect to the Obligations. The Guarantor hereby waives any and
all rights (including, without limitation, defenses) it may have as a surety in
respect of the Borrower. The guarantee contained in this Article VII shall be
construed as a continuing, absolute and unconditional guarantee of payment and
performance without regard to (a) the validity or enforceability of this
Agreement, any other Loan Document or any of the documents executed in
connection therewith, any of the Obligations or any collateral security therefor
or guarantee or right of offset with respect thereto at any time or from time to
time held by the Administrative Agent or any Lender, (b) any defense (including,
without limitation, any statute of limitations), set-off or counterclaim (other
than a defense of payment or performance) which may at any time be available to
or be asserted by the Borrower against the Administrative Agent or any Lender,
or (c) any other circumstance whatsoever (with or without notice to or knowledge
of the Borrower or the Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Borrower for the Obligations,
or of the Guarantor (including, without limitation, any defense of a surety or
guarantor) under the guarantee contained in this Article VII, in bankruptcy or
in any other instance. When pursuing their rights and remedies hereunder against
the Guarantor, the Administrative Agent, the Agents and any Lender may, but
shall be under no obligation to, pursue such rights and remedies as they may
have against the Borrower or any other Person or against any collateral security
or guarantee for the Obligations or any right of offset with respect thereto,
and any failure by the Administrative Agent, the Agents or any Lender to pursue
such other rights or remedies or to collect any payments from the Borrower or
any such other Person or to realize upon any such collateral security or
guarantee or to exercise any such right of offset, or any release of the
Borrower or any such other Person or of any such collateral security, guarantee
or right of offset, shall not relieve the Guarantor of any liability hereunder,
and shall not impair or affect the rights and remedies, whether express, implied
or available as a matter of law, of the Administrative Agent, the Agents or any
Lender against the Guarantor.

         SECTION 7.5 Reinstatement. The Guarantee contained in this Article VII
shall continue to be effective, or be reinstated, as the case may be, if at any
time payment, or any part thereof, of any of the Obligations is rescinded or
must otherwise be restored or returned by the Administrative Agent, the Agents
or any Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Borrower or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any substantial part of its property, or otherwise, all as though
such payments had not been made.

         SECTION 7.6 Payments. The Guarantor hereby agrees that the amounts
payable by the Guarantor hereunder will be paid to the Administrative Agent
without set-off or counterclaim in Dollars at the Payment Office

         SECTION 7.7 Binding on Successors and Assigns. The Guarantor hereby
agrees that the provisions of this Article VII, and the obligations of the
Guarantor hereunder, shall be binding upon the Guarantor's successors and
assigns, and shall inure to the benefit of the Administrative Agent, the Agents
and the Lenders, and their respective successors, endorsees, transferees and
assigns.

                  (b) Any representation warranty or agreement made or deemed
         made by any Loan Party herein or in any other Loan Document or which is
         contained in any certificate, document or financial or other statement
         furnished by it at any time under or in connection with this Agreement
         or any such other Loan Document shall prove to have been incorrect in

         for a period of 30 days after notice to the Borrower from the
         Administrative Agent or the Majority Lenders; or

                  (e) Any Loan Party shall (i) default in making any payment of

         agreement or condition relating to any Indebtedness or contained in any
         instrument or agreement evidencing, securing or relating thereto, or
         any other event shall occur or condition exist, the effect of which
         default or other event or condition is to cause, or to permit the
         holder or beneficiary of such Indebtedness (or a trustee or agent or
         other party on behalf of such holder or beneficiary) to cause, with or
         without the giving of notice if required, such Indebtedness to become
         due prior to its stated maturity or, in the case of any such
         Indebtedness constituting a Guarantee Obligation, to become payable;
         provided, that a default, event or condition described in clause (i),

         Default under this Agreement unless, at the time of such default, one
         or more defaults, events or conditions of the type described in clauses
         (i), (ii) and (iii) of this

                  (i), (iii) or (iv) of this paragraph (k) in the event that
                  such Conservatorship or Estate, after making such effort as
                  the Administrative Agent deems appropriate, and by reason of
                  evidence that the Administrative Agent deems reasonable,
                  concludes that such Conservatorship or Estate does not have
                  the legal power and authority under the laws of the state or
                  jurisdiction binding the actions of such Conservatorship or
                  Estate to take the actions required.

         For purposes of this paragraph (k), the laws governing the actions of
         the Conservatorship or the Estate shall be the laws of the state of
         jurisdiction of the primary residence of the Guarantor or, if a
         Conservator is appointed in another jurisdiction and the Administrative
         Agent in its reasonable judgment deems it acceptable, the laws of the
         state in which such Conservator is appointed. Any action required to be
         taken or duties required to be performed hereunder by a Conservator on
         behalf of a Conservatorship or by the Estate shall be taken or
         performed by such Conservator or Estate in a fiduciary, and not
         individual, capacity, provided that such Conservator or Estate has
         complied in good faith with the terms and conditions of this Agreement
         and the other Loan Documents; or

                  (l) (i) Any "accumulated funding deficiency" (as defined in
         section 302 of ERISA) shall exist with respect to any Plan, or any Lien
         shall arise on the assets of any Loan Party or any Commonly Controlled
         Entity in favor of the PBGC or a Plan, (ii) any Loan Party or any
         Commonly Controlled Entity shall or in the opinion of the Majority
         Lenders is likely to, incur any liability in connection with a
         withdrawal from, or the insolvency or reorganization of, a
         Multiemployer Plan or (iii) any other event or condition shall occur or
         exist with respect to a Plan; and in each case in clauses (i) through
         (iii), such event or condition, together with all other such events or
         conditions, if any, could reasonably be expected to have a Material
         Adverse Effect;

then, and in any such event, (x) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) of this Section 8.1 with respect to the
Borrower, automatically the Commitments shall immediately terminate and each
Lender's Loan hereunder (with accrued interest thereon) and all other amounts
owing under this Agreement and the other Loan Documents shall immediately become
due and payable, and (y) if such event is any other Event of Default, either or
both of the following actions may be taken: (i) with the consent of the Majority
Lenders, the Administrative Agent may, or upon the request of the Majority
Lenders, the Administrative Agent shall, by notice to the Borrower declare the
Commitments to be terminated forthwith, whereupon the Commitments shall
immediately terminate; and (ii) with the consent of the Majority Lenders, the
Administrative Agent may, or upon the request of the Majority Lenders, the
Administrative Agent shall, by notice to the Borrower, declare each Lender's
Loan hereunder (with accrued interest thereon) and all other amounts owing under
this Agreement and the other Loan Documents to be due and payable forthwith,
whereupon the same shall immediately become due and payable.

         Except as expressly provided above in this Article VIII, presentment,
demand, protest and all other notices of any kind are hereby expressly waived.

                                   ARTICLE IX

                            THE ADMINISTRATIVE AGENT

         SECTION 9.1 Appointment. Each Lender hereby irrevocably designates and
appoints the Administrative Agent as the agent of such Lender under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes the Administrative Agent, in such capacity, to take such action on
its behalf under the provisions of this Agreement and the other Loan Documents
and to exercise such powers and perform such duties as are expressly delegated
to the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

         SECTION 9.2 Delegation of Duties. The Administrative Agent may execute
any of its duties under this Agreement and the other Loan Documents by or
through agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or attorneys
in-fact selected by it with reasonable care.

         SECTION 9.3 Exculpatory Provisions. Neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders or
the holder of any Note for any recitals, statements, information,
representations or warranties made by any Loan Party or any representative
thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of any Loan Party to perform its obligations
hereunder or thereunder. The Administrative Agent shall not be under any
obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of any Loan Party.

         SECTION 9.4 Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
writing, resolution, notice, consent, certificate, affidavit, letter, telecopy,
telex or teletype message, statement, order or other


                                      -43-

<PAGE>   49

document or conversation believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel (including, without limitation, counsel to any Loan
Party), independent accountants and other experts selected by the Administrative
Agent. The Administrative Agent shall be fully justified in failing or refusing
to take any action under this Agreement or any other Loan Document unless it
shall first receive such advice or concurrence of the Majority Lenders (or such
other requisite Lenders as may be expressly required by any Loan Document) as it
deems appropriate or it shall first be indemnified to its satisfaction by the
Lenders against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action. The Administrative Agent
shall in all cases be fully protected in acting, or in refraining from acting,
under this Agreement and the other Loan Documents in accordance with a request
of the Majority Lenders (or such other requisite Lenders as may be expressly
required by any Loan Document), and such request and any action taken or failure
to act pursuant thereto shall be binding upon all the Lenders and all future
holders of the obligations owing by the Borrower hereunder.

         SECTION 9.5 Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Administrative Agent has received notice from a
Lender or the Borrower or the Guarantor referring to this Agreement, describing
such Default or Event of Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent receives such a notice, the
Administrative Agent shall give notice thereof to the Lenders. The
Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Majority Lenders;
provided that unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the
Lenders.

         SECTION 9.6 Non-Reliance on Administrative Agent and Other Lenders.
Each Lender expressly acknowledges that neither the Administrative Agent nor any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates
has made any representations or warranties to it and that no act by the
Administrative Agent hereafter taken, including any review of the affairs of any
Loan Party, shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of each Loan Party and made its own decision to make its Loans
hereunder and enter into this Agreement. Each Lender also represents that it
will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial and other condition
and creditworthiness of each Loan Party. Except for copies of notices, reports
and other documents expressly required to be


                                      -44-

<PAGE>   50

furnished to the Lenders by the Administrative Agent hereunder, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, operations,
property, condition (financial or otherwise), prospects or creditworthiness of
any Loan Party which may come into the possession of the Administrative Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates.

         SECTION 9.7 Indemnification. The Lenders agree to indemnify the
Administrative Agent (and its officers, directors, employees, agents,
attorneys-in-fact and Affiliates) in its capacity as such (to the extent not
reimbursed by the Borrower or the Guarantor and without limiting the obligation
of the Borrower and the Guarantor to do so), ratably according to their
respective Exposure Percentages in effect on the date on which indemnification
is sought (or, if indemnification is sought after the date upon which the
Commitments shall have terminated and the Total Outstanding Extensions of Credit
shall have been reduced to zero, ratably in accordance with such Exposure
Percentages immediately prior to such date), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the amounts
owing hereunder) be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of, the Commitments,
this Agreement, any of the other Loan Documents or any documents contemplated by
or referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by the Administrative Agent under or in
connection with any of the foregoing; provided that no Lender shall be liable
for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Administrative Agent's gross negligence or willful
misconduct. The agreements in this Article IX shall survive the payment of each
Lender's Loan and all other amounts payable hereunder.

         SECTION 9.8 Administrative Agent in Its Individual Capacity. The
Administrative Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with each Loan Party as though the
Administrative Agent were not the Administrative Agent hereunder and under the
other Loan Documents. With respect to the Loan made by it, the Administrative
Agent shall have the same rights and powers under this Agreement and the other
Loan Documents as any Lender and may exercise the same as though it were not the
Administrative Agent, and the terms "Lender" and "Lenders" shall include the
Administrative Agent in its individual capacity.

         SECTION 9.9 Successor Administrative Agent. The Administrative Agent
may resign as Administrative Agent at any time upon 15 days' notice to the
Lenders, the Borrower and the Guarantor. If the Administrative Agent shall
resign as Administrative Agent under this Agreement and the other Loan
Documents, then the Majority Lenders shall appoint from among the Lenders a
successor agent for the Lenders, which successor agent shall be approved by the
Borrower, whereupon such successor agent shall succeed to the rights, powers and
duties of the Administrative Agent, and the term "Administrative Agent" shall
mean such successor agent effective upon such appointment and approval, and the
former Administrative Agent's rights, powers and duties as Administrative Agent
shall be terminated, without any other or further act


                                      -45-

<PAGE>   51

or deed on the part of such former Administrative Agent or any of the parties to
this Agreement or any holders of the Loans. If no successor Administrative Agent
has been appointed by the 15th Business Day after the date such notice of
resignation was given, the Lenders shall thereafter perform all of the duties of
the Administrative Agent hereunder and/or under any other Loan Document until
such time, if any, as the Lenders appoint a successor Administrative Agent.
After any retiring Administrative Agent's resignation as Administrative Agent,
the provisions of this Article IX shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Loan Documents.

         SECTION 9.10 The Arrangers, Co-Syndication Agents and Documentation
Agent. None of the Arrangers, the Co-Syndication Agents or the Documentation
Agent shall have any duties or responsibilities under this Agreement or any of
the Loan Documents.

                                    ARTICLE X

                                  MISCELLANEOUS

         SECTION 10.1 Amendments and Waivers. Neither this Agreement nor any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
Section 10.1. The Majority Lenders may, or, with the written consent of the
Majority Lenders, the Administrative Agent may, from time to time, (a) enter
into with the relevant Loan Party or Loan Parties written amendments,
supplements or modifications hereto and to the other Loan Documents for the
purpose of adding any provisions to this Agreement or the other Loan Documents
or changing in any manner the rights of the Lenders or of any Loan Party
hereunder or thereunder or (b) waive, on such terms and conditions as the
Majority Lenders or the Administrative Agent, as the case may be, may specify in
such instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided,
however, that no such waiver and no such amendment, supplement or modification
shall (i) reduce the amount or extend the scheduled date of final maturity of
any Loan or of any scheduled installment thereof, or reduce the stated rate of
any interest, fee or commission payable to any Lender hereunder or extend the
scheduled date of any payment thereof or increase the amount or extend the
expiration date of any Lender's Commitment, in each case without the consent of
each Lender directly affected thereby, or (ii) amend, modify or waive any
provision of this Section 10.1 or reduce the percentage specified in the
definition of Majority Lenders or Super-Majority Lenders, or consent to the
assignment or transfer by the Borrower or the Guarantor of any of its rights and
obligations under this Agreement and the other Loan Documents, or release all or
substantially all of the Pledged Microsoft Stock, or terminate the Guarantee
contained in Article VII, in each case without the written consent of all the
Lenders, or (iii) amend, modify or waive any provision of Section 4.1(f) without
the written consent of the Super-Majority Lenders, or (iv) amend, modify or
waive any provision of Article IX without the written consent of the then
Administrative Agent, or (v) amend, modify or waive any provision of Section
2.4(c), (d) or (e) without the written consent of the Super-Majority Lenders and
(b) thereafter, the aggregate unpaid principal amount of the Loans then
outstanding. Any such waiver and any such amendment, supplement or modification
shall apply equally to each of the Lenders and shall be binding upon the
Borrower,


                                      -46-

<PAGE>   52

the Guarantor, the Lenders, the Agents, the Administrative Agent and all future
holders of the obligations owing hereunder. In the case of any waiver, the
Borrower, the Guarantor, the Lenders and the Administrative Agent shall be
restored to their former positions and rights hereunder and under the other Loan
Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing; no such waiver shall extend to any subsequent or other
Default or Event of Default or impair any right consequent thereon.

         SECTION 10.2  Notices.

         (a) Unless otherwise specifically provided in this Agreement, all
notices, requests and other communications provided for hereunder shall be in
writing (including, unless the context expressly otherwise provides, facsimile
transmission, provided that any matter transmitted by facsimile transmission (i)
shall be immediately confirmed by a telephone call to the recipient at the

original thereof) and mailed, sent by facsimile transmission, or delivered, to

shall not have any liability to the Borrower or the Guarantor, as the case may
be or other Person on account of any action taken or not taken by the
Administrative Agent and the Lenders in reliance upon such telephonic or

privilege. The rights, remedies, powers and privileges herein provided are
cumulative and not exclusive of any rights, remedies, powers and privileges
provided by law.

         SECTION 10.4 Survival of Representations and Warranties. All
representations and warranties made hereunder, in the other Loan Documents and

of this Agreement and the making of each Lender's Loan hereunder.

         SECTION 10.5 Payment of Expenses and Taxes. The Borrower agrees (a),
whether or not the transactions herein contemplated are consummated, (i) to pay
or reimburse each of the Administrative Agent and the Lead Arranger for all its
reasonable out-of-pocket costs and expenses incurred in connection with the
development, preparation, syndication and execution of this Agreement, the other

counsel to the Administrative Agent and the Lead Arranger and (iii) to pay or
reimburse each Lender, the Administrative Agent and the Agents for all costs and
expenses incurred in connection with the enforcement or preservation of any
rights under this Agreement and the other Loan Documents, each as amended,
supplemented or modified, and any such other documents, including, without
limitation, the fees and disbursements of counsel (including the allocated fees
and expenses of in-house counsel) to each Lender and of counsel to the
Administrative Agent and the Agents, (b) to pay, indemnify, and hold harmless
each Lender, the Administrative Agent and Agents from, any and all recording and
filing fees and any and all liabilities with respect to, or resulting from any
delay in paying, stamp, excise and other similar taxes, if any, which may be
payable or determined to be payable in connection with the execution and
delivery of, or consummation or administration of any of the transactions
contemplated by, or any amendment, supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, the other Loan Documents and
any such other documents, and (c) to pay, indemnify, and hold harmless each
Lender, the Administrative Agent, the Agents, their Affiliates and each of their
respective officers, directors, employees, affiliates, agents and controlling
persons (each, an "indemnitee") from and against any and all other liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever (including, without
limitation, fees, charges and disbursements of counsel to such indemnitee) with
respect to the syndication, execution, delivery, enforcement, performance and
administration of this Agreement, the other Loan Documents or any actual or
proposed use of proceeds of any Loan (all the foregoing in this clause (c),
collectively, the "indemnified liabilities"), provided, that the Borrower shall
have no obligation hereunder to any individual indemnitee with respect to
indemnified liabilities arising from the gross negligence or willful misconduct
of such indemnitee. The agreements in this Section 10.5 shall survive the
termination of the Commitments and the repayment of each Lender's Loan and all
other amounts payable hereunder.

         SECTION 10.6 Successors and Assigns; Participations and Assignments.

         (a) This Agreement shall be binding upon and inure to the benefit of
the Borrower, the Guarantor (and any heirs, executors and administrators of the
Guarantor and the successors and assigns of such Persons), the Lenders, the
Administrative Agent, the Agents and their respective successors and assigns,
except that neither the Borrower nor the Guarantor (nor any


                                      -49-

<PAGE>   55

heirs, executors or administrators of the Guarantor or any successors or assigns
of such Persons) may assign or transfer any of its rights or obligations under
this Agreement without the prior written consent of each Lender.

         (b) Any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time sell to one or more banks or other
entities ("Participants") participating interests in any Loan owing to such
Lender, any Commitment of such Lender or any other interest of such Lender
hereunder and under the other Loan Documents. In the event of any such sale by a
Lender of a participating interest to a Participant, such Lender's obligations
under this Agreement to the other parties to this Agreement shall remain
unchanged, such Lender shall remain solely responsible for the performance
thereof, such Lender shall remain the holder of any such Loan for all purposes
under this Agreement and the other Loan Documents, and the Borrower and the
Administrative Agent shall continue to deal solely and directly with such Lender
in connection with such Lender's rights and obligations under this Agreement and
the other Loan Documents. In no event shall any Participant under any such
participation have any right to approve any amendment or waiver of any provision
of any Loan Document, or any consent to any departure by any Loan Party
therefrom, except to the extent that such amendment, waiver or consent would
reduce the principal of, or interest on, any Loan or any fees payable hereunder,
or postpone the date of the final maturity of any Loan, in each case to the
extent subject to such participation. The Borrower agrees that each Participant
shall be entitled to the benefits of Sections 2.11, 2.12 and 2.13 with respect
to its participation in the Commitments and the Loan outstanding from time to
time as if it were a Lender; provided that, in the case of Section 2.12, such
Participant shall have complied with the requirements of said Section and
provided, further, that no Participant shall be entitled to receive any greater
amount pursuant to any such Section than the transferor Lender would have been
entitled to receive in respect of the amount of the participation transferred by
such transferor Lender to such Participant had no such transfer occurred.

         (c) Any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time and from time to time assign to any
Lender or any affiliate thereof or any Approved Fund or, with the consent of the
Borrower (in each case, so long as no Default or Event of Default has occurred
or is continuing) and the Administrative Agent (which in each case shall not be
unreasonably withheld; it being understood that it shall be reasonable for the
Administrative Agent to withhold consent to an assignment to an assignee that
would be subject to U.S. federal withholding taxation on the date of transfer),
to any other Person (collectively, "Purchasing Lenders") all or any part of its
rights and obligations under this Agreement and the other Loan Documents
pursuant to an Assignment and Acceptance, substantially in the form of Exhibit
E, executed by such Purchasing Lender, such transferor Lender (and, in the case
of a Purchasing Lender that is not then a Lender or an affiliate thereof or an
Approved Fund, by the Borrower and the Administrative Agent as permitted by this
Section 10.6(c)) and delivered to the Administrative Agent for its acceptance
and recording in the Register; provided that, except in the case of an
assignment to a Lender or any affiliate thereof or an Approved Fund or an
assignment of all of a Lender's rights and obligations under this Agreement, (x)
the amount of the Commitment and/or Loan of the assigning Lender being assigned
pursuant to each such assignment shall equal at least $5,000,000 and (y) after
giving effect to each such assignment, the


                                      -50-

<PAGE>   56

amount of the remaining Commitment and/or Loan of the assigning Lender shall
equal at least $10,000,000 (or, in each case, such lesser amount as the Borrower
and the Administrative Agent may consent to). Upon such execution, delivery,
acceptance and recording, from and after the effective date determined pursuant
to such Assignment and Acceptance, (x) the Purchasing Lender thereunder shall be
a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder with a Commitment and/or
Loan as set forth therein, and (y) the transferor Lender thereunder shall, to
the extent provided in such Assignment and Acceptance, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an transferor Lender's
rights and obligations under this Agreement, such transferor Lender shall cease
to be a party hereto). Such Assignment and Acceptance shall be deemed to amend
this Agreement to the extent, and only to the extent, necessary to reflect the
addition of such Purchasing Lender and the resulting adjustment of Exposure
Percentages arising from the purchase by such Purchasing Lender of all or a
portion of the rights and obligations of such Transferor Lender.

         (d) The Administrative Agent, on behalf of the Borrower, shall maintain
at the address of the Administrative Agent referred to in Section 10.2 a copy of
each Assignment and Acceptance delivered to it and a register (the "Register")
for the recordation of the names and addresses of the Lenders and the Commitment
of, and principal amount of the Loan owing to, each Lender from time to time.
The entries in the Register shall be conclusive, in the absence of manifest
error, and the Borrower, the Guarantor, the Administrative Agent and the Lenders
shall treat each Person whose name is recorded in the Register as the owner of a
Loan or other obligation hereunder as the owner thereof for all purposes of this
Agreement and the other Loan Documents, notwithstanding any notice to the
contrary. The Register shall be available for inspection by the Borrower or any
Lender at any reasonable time and from time to time upon reasonable prior
notice.

         (e) Upon its receipt of an Assignment and Acceptance executed by a
transferor Lender and a Purchasing Lender (and, in the case of an Assignee that
is not then a Lender or an affiliate thereof, by the Borrower and the
Administrative Agent), together with payment to the Administrative Agent of a
registration and processing fee of $3,500, the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the effective date
determined pursuant thereto record the information contained therein in the
Register and give notice of such acceptance and recordation to the Lenders and
the Borrower.

         (f) The Borrower authorizes each Lender to disclose to any Participant
or Assignee (each, a "Transferee") and any prospective Transferee, subject to
the provisions of Section 10.15, any and all financial information in such
Lender's possession concerning the Borrower and its Affiliates which has been
delivered to such Lender by or on behalf of the Borrower or the Guarantor
pursuant to this Agreement or which has been delivered to such Lender by or on
behalf of the Borrower or the Guarantor in connection with such Lender's credit
evaluation of the Borrower, the Guarantor and their Affiliates prior to becoming
a party to this Agreement.

         (g) Nothing herein shall prohibit (i) any Lender from pledging or
assigning all or any portion of its Loans to any Federal Reserve Bank in
accordance with applicable law or (ii) any


                                      -51-

<PAGE>   57

Lender that is a fund that invests in bank loans, from pledging, without the
consent of the Administrative Agent or the Borrower, all or any portion of its
Loans to any trustee for, or any other representative of, holders of obligations
owed, or securities issued, by such fund, as security for such obligations or
securities, provided that any foreclosure or similar action by such trustee or
representative shall be subject to the provisions of this Section 10.6
concerning assignments. In order to facilitate such pledge or assignment, the
Borrower hereby agrees that, upon request of any Lender at any time and from
time to time after the Borrower has made its initial borrowing hereunder, the
Borrower shall provide to such Lender, at the Borrower's own expense, a Note
evidencing the Loan owing to such Lender.

         SECTION 10.7 Adjustments; Set-off.

         (a) Except as otherwise expressly provided herein, if any Lender (a
"Benefited Lender") shall at any time receive any payment of all or part of its
Loans, or interest thereon, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by set-off, pursuant to events or
proceedings of the nature referred to in Section 8.1 (f), or otherwise), in a
greater proportion than any such payment to or collateral received by any other
Lender, if any, in respect of each such other Lender's Loans owing to each such
other Lender, or interest thereon, such benefited Lender shall purchase for cash
from the other Lenders a participating interest in such portion of each such
other Lender's Loan owing to each such other Lender, or shall provide such other
Lenders with the benefits of any such collateral, or the proceeds thereof, as
shall be necessary to cause such benefited Lender to share the excess payment or
benefits of such collateral or proceeds ratably with each of the Lenders;
provided, however, that if all or any portion of such excess payment or benefits
is thereafter recovered from such benefited Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest.

         (b) In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right following the occurrence and during the
continuance of any Event of Default, without prior notice to the Borrower or the
Guarantor, any such notice being expressly waived by the Borrower and the
Guarantor to the extent permitted by applicable law, upon any amount becoming
due and payable by the Borrower or the Guarantor hereunder (whether at the
stated maturity, by acceleration or otherwise) to set-off and appropriate and
apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or any branch or agency thereof to or for the credit or the
account of the Borrower or the Guarantor. Each Lender agrees promptly to notify
the Borrower or the Guarantor, as the case may be, and the Administrative Agent
after any such set-off and application made by such Lender, provided that the
failure to give such notice shall not affect the validity of such set-off and
application.

         SECTION 10.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by facsimile transmission), and all of said counterparts taken
together shall be deemed to constitute one and


                                      -52-

<PAGE>   58

the same instrument. A set of the copies of this Agreement signed by all the
parties shall be lodged with the Borrower and the Administrative Agent.

         SECTION 10.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         SECTION 10.10 Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the Guarantor, the Administrative
Agent, the Agents and the Lenders with respect to the subject matter hereof, and
there are no promises, undertakings, representations or warranties by the
Administrative Agent or any Lender relative to subject matter hereof not
expressly set forth or referred to herein or in the other Loan Documents.

         SECTION 10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

         SECTION 10.12 Submission To Jurisdiction; Waivers. Each Loan Party
hereby irrevocably and unconditionally:

                  (a) Submits for itself and its property, in any legal action
         or proceeding relating to this Agreement and the other Loan Documents
         to which it is a party, or for recognition and enforcement of any
         judgment in respect thereof, to the non-exclusive general jurisdiction
         of the Courts of the State of New York, the courts of the United States
         of America for the Southern District of New York, and appellate courts
         from any thereof;

                  (b) Consents that any such action or proceeding may be brought
         in such courts and waives any objection that it or now or hereafter has
         to the venue of any such action or proceeding in any such court or that
         such action or proceeding was brought in an inconvenient court and
         agrees not to plead or claim the same;

                  (c) Agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to such Loan Party its address set forth in Section 10.2 or at
         such other address of which the Administrative Agent shall have been
         notified pursuant thereto;

                  (d) Agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other Jurisdiction; and


                                      -53-

<PAGE>   59

                  (e) Waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred to in this Section any special, exemplary, punitive or
         consequential damages.

         SECTION 10.13 Acknowledgments. Each Loan Party hereby acknowledges
that:

                  (a) It has been advised by counsel in the negotiation,
         execution and delivery of this Agreement and the other Loan Documents;

                  (b) Neither the Administrative Agent nor any Lender has any
         fiduciary relationship with or duty to the Borrower or the Guarantor
         arising out of or in connection with this Agreement or any of the other
         Loan Documents, and the relationship between Administrative Agent and
         Lenders, on one hand, and the Borrower or the Guarantor, on the other
         hand, in connection herewith or therewith is solely that of debtor and
         creditor; and

                  (c) No joint venture is created hereby or by the other Loan
         Documents or otherwise exists by virtue of the transactions
         contemplated hereby among the Lenders or among the Borrower or the
         Guarantor and the Lenders.

         SECTION 10.14 WAIVERS OF JURY TRIAL. THE BORROWER, THE GUARANTOR, THE
ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY

         SECTION 10.15 Confidentiality. Each of the Administrative Agent and
each Lender agrees to keep confidential all financial information provided
pursuant to Sections 5.1 or 5.2 and any other non-public information provided to
it by any Loan Party pursuant to this Agreement that is designated by such Loan
Party as confidential; provided that nothing herein shall prevent the
Administrative Agent or any Lender from disclosing any such information (a) to
the Administrative Agent, any other Lender or any Affiliate thereof, (b) to any
Transferee or prospective Transferee which agrees to comply with the provisions
of this Section 10.15, (c) to the employees, directors, agents, attorneys,
accountants and other professional advisors of such Lender or its affiliates,
(d) upon the request or demand of any Governmental Authority having jurisdiction

pursuant to applicable law or regulation, (f) if requested or required to do so
in connection with any litigation or similar proceeding, (g) which has been
publicly disclosed other than in breach of this Section 10.15, or (h) in
connection with the exercise of any remedy hereunder or under any other Loan

result of any failure to fulfill the applicable conditions to such Advance set
forth in Article III on or before the date for such Advance specified in the
notice from or on behalf of the Borrower to the Bank requesting such Advance,
then the Borrower shall pay to the Bank, upon demand by the Bank, an amount
equal to the difference (if a positive number) obtained by subtracting (i) the
amount of interest that would have accrued on such Advance at an interest rate
per annum equal to the rate of interest per annum at which deposits in United
States dollars are offered by the principal office of the Bank in London,
England, to prime banks in the London interbank market at 11:00 a.m. (London
time) on the date for such Advance specified in the notice from or on behalf of
the Borrower to the Bank requesting such Advance in an amount substantially
equal to such Advance and for a period equal to the Interest Period specified in
the notice from or on behalf of the Borrower to the Bank requesting such Advance
from (ii) the amount of interest that would have accrued on such Advance at the
Eurodollar Rate [*] percent ([*]%) per annum or the Reference Rate [*] percent
(*%) per annum, as the case may be, that would have been applicable to such
Advance during the Interest Period for such Advance specified in the notice from
or on behalf of the Borrower to the Bank requesting such Advance.

        SECTION 2.3 Responsibility for Requests for Advances.

                (a)     The Borrower hereby authorizes the Bank to make Advances
under this Agreement upon notice given by the Borrower or upon notice given on
behalf of the Borrower by any one or more of [*] and any other Person designated
in writing by the Borrower to the Bank from time to time, each of whom shall at
all times continue to be authorized by the Borrower to request Advances on
behalf of the Borrower under this Agreement until receipt by the Bank of written
notice from the Borrower of the revocation of such authority of any such Person.
Each Advance made by the Bank upon notice given by the Borrower or by any of [*]
or any other Person designated in writing by the Borrower to the Bank shall be
conclusively presumed to have been made to or for the benefit of the Borrower
when made by the Bank in accordance with such notice and deposited in or
credited to any account of the Borrower with the Bank, regardless of whether any
Person (including, but not limited to, any Person authorized to request Advances
on behalf of the Borrower) other than the Borrower also shall have authority to
withdraw funds from any such account. The Borrower agrees to repay, and to pay
interest on, any Advance that is so made, deposited or credited by the Bank.

                (b)     The Borrower acknowledges and agrees that the making by
the Bank of Advances in response to notices given via telephone facsimile
communications is in the interest of the Borrower and that the Bank cannot
effectively determine whether a specific notice requesting an Advance and
purporting to have been made by or on behalf of the Borrower is actually
authorized or authentic. In order to induce the Bank to make Advances in
response to notices given via telephone facsimile communications, the Borrower
hereby assumes all risks regarding the validity, authenticity and due
authorization of all notices requesting Advances that are purported to be given
by or on

                                       14

behalf of the Borrower, whether or not the Person giving such notice has
authority in fact to request Advances on behalf of the Borrower and whether or
not the requested Advance or the application of the proceeds of such Advance
constitutes an Event of Default or would constitute an Event of Default but for
the requirement that notice be given or time elapse or both. The Bank shall
incur no liability to the Borrower in acting upon any notice or other
communication, whether given via telephone facsimile or telex or otherwise in
writing, which the Bank believes in good faith to have been given by any Person
authorized to give notices requesting Advances on behalf of the Borrower or in
otherwise acting in good faith under this Agreement.

installment due on or prior to the date of the initial Advance, and the

and 2003; provided that if the unused portion of the Commitment is terminated in
whole pursuant to Section 2.5, Section 2.9 or Section 7.1, then the entire
unpaid balance of the facility fee referred to in Section 2.4(b) shall become
and be forthwith due and payable, without presentment, demand, protest or any
notice of any kind, all of which are hereby expressly waived by the Borrower.

        SECTION 2.5 Reduction and Termination of the Commitment. The Borrower
shall have the right, upon at least two Business Days notice to the Bank, to

        be Converted or paid in full.

                        (ii)    Eurodollar Rate Advances. During such periods as

        Interest Period, payable monthly on the last day of each calendar month
        and on the last day of such Interest Period.

                        (iii)   Reference Rate Advances. During such periods as
        such Advance is a Reference Rate Advance, a rate per annum equal at all
        times during the Interest Period for such Advance to the Reference Rate

                (b)     Default Interest. The Borrower shall pay interest on the

(i) in the case of any amount of principal, the greater of (A) [*] percent
([*]%) per annum above the rate per annum required to be paid on such Advance
immediately prior to the date on which such amount became due and (B) [*]
percent [*]%) per annum above the Base Rate in effect from time to time, and
(ii) in the case of all other amounts, [*] percent ([*]%) per annum above the
Base Rate in effect from time to time.

                (c)     Interest Periods. The duration of each Interest Period
shall be (i) one, two, three, four, five, six, seven, eight, nine, ten, eleven

                        (A)     the duration of any Interest Period which
        commences before September 20, 2004, and would otherwise end after such
        date shall end on such date; and

                        (B)     whenever the last day of any Interest Period
        would otherwise occur on a day other than a Business Day, the last day
        of such Interest Period shall be extended to occur on the next
        succeeding Business Day; provided that, in the case of any Interest
        Period for a Eurodollar Rate Advance, if such extension would cause the
        last day of such Interest Period to occur in the next following calendar
        month, then the last day of such Interest Period shall occur on the next
        preceding Business Day.

                (d)     Reference Rate. The term "Reference Rate" means, for any
Interest Period for any Advance, the rate per annum quoted by the Bank to the
Borrower, and agreed to by the Borrower, at any time for such Interest Period;
provided that if no rate per annum shall be agreed between the Borrower and the
Bank prior to the first day of such Interest Period as the Reference Rate for
such Interest Period, such Advance shall be a Base Rate Advance during such
Interest Period. Within two Business Days after the first day of such Interest
Period, the Bank shall send to the Borrower a confirmation of the Reference Rate
quoted to and agreed to by the Borrower, if any (and if no Reference Rate was
agreed to by the Borrower, a

<PAGE>   23

confirmation of the Base Rate), for such Interest Period, and unless the
Borrower shall object thereto within one Business Day after the Bank shall send
such confirmation, such confirmation shall be conclusive. If the Borrower
objects to the Reference Rate specified in such confirmation for any Advance
within one Business Day after the Bank shall send such confirmation, then such
Advance shall be a Base Rate Advance during such Interest Period, and the
Borrower shall pay to the Bank, upon demand by the Bank, an amount equal to the
difference (if a positive number) obtained by subtracting the amount of interest
that would have accrued on such Advance at the LIBO Rate from the amount of

(ii) the Advances, the Note, all interest thereon and all other amounts payable
under this Agreement and the other Loan Documents shall automatically become and
be due and payable on the ninetieth day after the earlier to occur of the date

protest or any notice of any kind, all of which are hereby expressly waived by
the Borrower.

<PAGE>   24

Investment, together with all accrued and unpaid interest thereon through the
date of prepayment.

        SECTION 2.10 Increased Costs. If, due to either (a) the introduction of
or any change (other than any change by way of imposition or increase of reserve
requirements referred to in Section 2.11) in or in the interpretation of any law
or regulation or (b) the compliance with any guideline or request from any
central bank or other governmental authority (whether or not having the force of
law), there shall be any increase in the cost to the Bank of agreeing to make or
making, funding or maintaining Eurodollar Rate Advances or Reference Rate
Advances, then the Borrower shall from time to time, upon demand by the Bank,
pay to the Bank additional amounts sufficient to compensate the Bank for such
increased cost incurred or accrued by the Bank not more than ninety days prior
to the date of such demand by the Bank. A certificate as to the amount of such
increased cost, submitted to the Borrower by the Bank, shall be conclusive and
binding for all purposes, absent manifest error.

        SECTION 2.11 Additional Interest. The Borrower shall pay to the Bank, so
long as the Bank shall be required under regulations of the Board of Governors
of the Federal Reserve System to maintain reserves with respect to liabilities
or assets consisting of or including Eurocurrency liabilities (as such term is
defined in Regulation D of the Board of Governors of the Federal Reserve System,
as in effect from time to time), additional interest on the unpaid principal
amount of each Eurodollar Rate Advance, from the date of such Advance until such
principal amount is paid in full, at an interest rate per annum equal at all
times to the remainder obtained by subtracting (a) the LIBO Rate for the
Interest Period for such Advance from (b) the rate obtained by dividing such
LIBO Rate by a percentage equal to 100% minus the reserve percentage applicable
during such Interest Period (or if more than one such percentage shall be so
applicable, the daily average of such percentages for those days in such
Interest Period during which any such percentage shall be so applicable) under
regulations issued from time to time by the Board of Governors of the Federal
Reserve System (or any successor) for determining the maximum reserve
requirement (including, but not limited to, any emergency, supplemental or other
marginal reserve requirement) for the Bank with respect to liabilities or assets
consisting of or including Eurocurrency liabilities having a term equal to such
Interest Period, payable on each date on which interest is payable on such
Advance. Such additional interest shall be determined by the Bank and notified
to the Borrower, and such determination by the Bank shall be conclusive and
binding for all purposes, absent manifest error.

        SECTION 2.12 Increased Capital. If the Bank determines that compliance
with any law or regulation or any guideline or request from any central bank or
other governmental authority (whether or not having the force of law) affects or
would affect the amount of capital required or expected to be maintained by the
Bank or any corporation controlling the Bank and that the amount of such capital
is increased by or based upon the existence of the Bank's commitment to lend
hereunder and other commitments of this type, then, upon demand by the Bank
within ninety days after such increase in capital, the Borrower shall
immediately pay to the Bank, from time to time as specified by the Bank,
additional amounts sufficient to compensate the Bank or such 



                                       18

<PAGE>   25

corporation in the light of such circumstances, to the extent that the Bank
reasonably determines such increase in capital to be allocable to the existence
of the Bank's commitment to lend hereunder. A certificate as to such amounts
submitted to the Borrower by the Bank shall be conclusive and binding for all
purposes, absent manifest error.

        SECTION 2.13 Interest Rate Protection.

                (a)     If the Borrower shall fail to select the duration of any
Interest Period for any Eurodollar Rate Advance or any Reference Rate Advance in
accordance with the provisions of Section 2.7(c), the Bank will forthwith so
notify the Borrower and such Advance will automatically, on the last day of the
then existing Interest Period therefor, Convert into a Base Rate Advance.

                (b)     On the date on which the sum of the unused portion of
the Commitment plus the aggregate unpaid principal amount of the Advances shall
be reduced, by payment or prepayment or otherwise, to less than $2,500,000.00,
any and all Advances that are of a Type other than Base Rate Advances
automatically shall Convert into Base Rate Advances and, on and after such date,
the right of the Borrower to Convert such Advances into Advances of a Type other
than Base Rate Advances shall terminate.

        SECTION 2.14 Voluntary Conversion of Advances. The Borrower may on any
Business Day, upon notice given to the Bank not later than 12:00 noon (New York
City time) on the third Business Day prior to the date of the proposed
Conversion and subject to the provisions of Sections 2.7 and 2.15, Convert an
Advance of one Type into an Advance of another Type; provided that, except as
otherwise provided in Section 2.15(a), any Conversion of any Eurodollar Rate
Advance or any Reference Rate Advance into an Advance of another Type shall be
made on, and only on, the last day of an Interest Period for such Eurodollar
Rate Advance or such Reference Rate Advance, as the case may be; provided,
further, that the Borrower may not Convert an Advance into a Eurodollar Rate
Advance or a Reference Rate Advance if the principal amount of the Advance to be
Converted is less than $2,500,000.00, unless, on the date of such Conversion,
the Borrower also obtains other Advances pursuant to Sections 2.1, 2.2 and 2.7

notwithstanding, if the Bank shall notify the Borrower that the introduction of,
or any change in or in the interpretation of, any law or regulation makes it
unlawful, or that any central bank or other governmental authority asserts that

so due.

                (c)     All computations of interest and of commitment fees
shall be made by the Bank on the basis of a year of 360 days, in each case for
the actual number of days (including the first day, but excluding the last day)
occurring in the period for which such interest or commitment fees are payable.
Each determination by the Bank of an interest rate hereunder shall be conclusive
and binding for all purposes, absent manifest error.

                (d)     Whenever any payment under any Loan Document shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such

        SECTION 2.17 Taxes.

                (a)     Any and all payments by the Borrower hereunder or under

excluding, in the case of the Bank, net income taxes that are imposed by the
United States and franchise taxes and net income taxes that are imposed on the
Bank by the state or foreign jurisdiction under the laws of which the Bank is
organized or any political subdivision thereof (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable to the Bank hereunder or
under the Note, (i) the sum payable shall be increased as may be necessary so
that after making all required deductions (including, but not limited to,
deductions applicable to additional sums payable under this Section 2.17) the
Bank receives an amount equal to the sum the Bank would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law.

                (b)     In addition, the Borrower shall pay any present or

that arise from any payment made hereunder or under the Note or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or the Note (all such taxes, charges and levies being hereinafter
referred to as "Other Taxes").

                (c)     The Borrower shall indemnify the Bank for the full

jurisdiction on amounts payable under this Section 2.17, paid by the Bank and
any liability (including, but not limited to, penalties, additions to tax,
interest and expenses) arising therefrom or with respect thereto. This
indemnification shall be made within thirty days from the date the Bank makes
written demand therefor.

Taxes, the Borrower shall furnish to the Bank, at the Bank's address referred to
in Section 8.2, the original receipt of payment thereof or a certified copy of
such receipt. In the case of any payment hereunder or under the Note by the
Borrower through an account or branch outside the United States or on behalf of
the Borrower by a payor that is not a United States person, if the Borrower
determines that no Taxes are payable in respect thereof, the Borrower shall
furnish, or shall cause such payor to furnish, to the Bank, at such address of
the Bank, an opinion of counsel acceptable to the Bank stating that such payment
is exempt from Taxes. For the purposes of this subsection (d) and subsection (a)
of this Section 2.17, the terms "United States" and "United States person" shall
have the respective meanings specified in section 7701 of the Internal Revenue
Code.

and interest hereunder and under the Note.

so that, immediately after giving effect to such prepayment and/or such other
actions, the Collateral Coverage Ratio shall be not greater than [*] percent
([*]%) and thereafter, so long as any of the Obligations shall remain unpaid in

        SECTION 6.2 Partial Release of Collateral. So long as no Event of

the Pledge Agreement, if at any time and from time to time after October 31,
1999, the Collateral Coverage Ratio shall be less than [*] percent ([*]%) for a
period of ninety consecutive days, then, upon request by the Borrower made
following each such period of ninety consecutive days, the Bank, at the
Borrower's expense, will release a portion of the Collateral (other than any
portion of the Collateral comprising any Hedged Shares or any other Pledged
Shares for which the Borrower and the Bank have then been provided protection
against a decrease in the market value of such Pledged Shares below a level or
price per share as specified in, and pursuant to, an Equity Hedge Agreement) so
that, immediately after giving effect to such release of such portion of the
Collateral, the Collateral Coverage Ratio shall be approximately (but not
greater than) [*] percent ([*]%). Upon any such partial release, the Bank, at
the Borrower's expense, will return to the Borrower the portion of the
Collateral so released and will execute and deliver to the Borrower such
documents as the Borrower shall reasonably request to evidence such partial
release.

        SECTION 6.3 Equity Hedge Agreements. If at any time the Borrower enters
into an Equity Hedge Agreement which provides to the Borrower and the Bank, for
a period less than the then remaining term of the Note, protection against a
decrease in the market value of any portion of the Pledged Shares below a level
or price per share satisfactory to the Bank as specified in such Equity Hedge
Agreement, then the Borrower shall give to the Bank, within ten Business Days
prior to the expiration or termination of such period of protection, notice
stating whether the Borrower will provide for the uninterrupted continuation of
such protection to the Borrower and the Bank by renewing such Equity Hedge
Agreement or entering into one or more replacement Equity Hedge Agreements with
respect to such Pledged Shares. Each notice from the Borrower to the Bank
stating that the Borrower will provide for the uninterrupted continuation of the
protection provided to the Borrower and the Bank under any Equity Hedge
Agreement shall be irrevocable and binding on the Borrower and, upon giving such
notice to the Bank, the Borrower, not less than five Business Days prior to the
expiration or termination of the period of such protection under such Equity
Hedge Agreement, shall renew such Equity Hedge Agreement or replace such Equity
Hedge Agreement with one or more replacement Equity Hedge Agreements
satisfactory to the Bank.

        SECTION 8.4 Costs, Expenses and Taxes.

                (a)     The Borrower agrees to pay on demand all reasonable
costs and expenses in connection with the preparation, execution, delivery,
administration, modification and amendment of the Loan Documents and the other
documents to be delivered under the Loan Documents, including, but not limited
to, the reasonable fees and out-of-pocket expenses of counsel for the Bank with
respect thereto and with respect to advising the Bank as to the Bank's rights
and responsibilities under the Loan Documents. The Borrower further agrees to
pay on demand all reasonable costs and expenses, if any (including, but not
limited to, reasonable counsel fees and expenses), in connection with the
enforcement (whether through negotiations, legal proceedings or otherwise) of
the Loan Documents and the other documents to be delivered under the Loan
Documents, including, but not limited to, reasonable counsel fees and expenses
in connection with the enforcement of rights under this Section 8.4(a).

                (b)     If any payment of principal of any Eurodollar Rate
Advance or any Reference Rate Advance is made other than on the last day of the
Interest Period for such Advance, as a result of any payment pursuant to Section
2.8(b), Section 2.9, Section 2.15 or Section 6.1 or as a result of acceleration
of the maturity of the Advances and the Note pursuant to Section 7.1 or for any
other reason, the Borrower shall pay to the Bank, upon demand by the Bank, an
amount equal to the difference (if a positive number) obtained by subtracting
the amount of interest that would have accrued on the amount of principal so
paid at the Market Rate during the remaining term of the relevant Interest
Period from the amount of interest that would have accrued on such amount of
principal at the Eurodollar Rate ([*] percent ([*]%) per annum) or the Reference
Rate ([*] percent ([*]%) per annum), as the case may be, that would have been
applicable to such amount of principal during the remaining term of the relevant
Interest Period. The term "Market Rate" means, for any payment of principal of
any Eurodollar Rate Advance or any Reference Rate Advance that is made or is
deemed to have been made other than on the last day of the Interest Period for
such Advance, a rate of interest per annum equal to the rate of interest per
annum at which deposits in United States dollars are offered by the principal
office of the Bank in London, England, to prime banks in the London interbank
market at 11:00 a.m. (London time) two Business Days before the date of such
principal payment in an amount substantially equal to the amount of such
principal payment and for a period substantially equal to the remaining term of
such Interest Period.

        SECTION 8.5 Right of Set-off. Upon the occurrence and during the
continuance of any Event of Default the Bank is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by the Bank to
or for the credit or the account of the Borrower against any and all of the
obligations of the Borrower now or hereafter existing under any Loan Document,
whether or not the Bank shall have made any demand under such Loan Document and
although such obligations may be unmatured. The Bank agrees promptly to notify
the Borrower after any such set-off and application; provided that the failure
to give such notice shall not affect the validity of such set-off and
application.

benefit of the Borrower, the Bank, the respective successors and assigns of the
Borrower and the Bank, and the heirs, executors, administrators and legal
representatives of the Borrower, except that the Borrower shall not have the
right to assign the Borrower's rights hereunder or any interest herein without

reason or for any reason.

                (b)     The Bank, without any notice to or consent of the
Borrower, may merge or consolidate with another entity and may sell
participations to one or more Persons in or to all or any portion of the Bank's
rights and obligations under this Agreement, the Note and any other Loan
Document (including, but not limited to, all or any portion of the Commitment,
the Advances and the Note); provided that in the case of sale of participations
(i) the Bank's obligations under this Agreement (including, but not limited to,

responsible to the Borrower for the performance of such obligations, (iii) the
Bank shall remain the holder of the Note for all purposes of this Agreement and
(iv) the Borrower shall continue to deal solely and directly with the Bank in
connection with the Bank's rights and obligations under this Agreement.

                (c)     The Bank, with the prior written consent of the
Borrower, which consent shall not be unreasonably withheld, may assign,
syndicate or otherwise transfer all or any portion of the Bank's rights and
obligations under this Agreement, the Note and any other Loan Document
(including, but not limited to, all or any portion of the Commitment, the
Advances and the Note) to any other Person, and such other Person shall
thereupon become vested with all the benefits in respect thereof granted to the
Bank in this Agreement or otherwise.

                (d)     Any other provision of this Agreement to the contrary
notwithstanding, the Bank may at any time create a security interest in all or

favor of any Federal Reserve Bank in accordance with Regulation A of the Board
of Governors of the Federal Reserve System.

                (e)     The Bank will use reasonable good faith efforts to hold
in confidence any Confidential Information, except to the extent that any such

are expected to be or become engaged in evaluating, approving,

material breach of this Agreement), Charter LLC or its designee is unwilling or

shall have the right and option (the "Put Option"), to sell and to permit any of
the Holder's Permitted Transferees to sell (provided such Permitted Transferees
were specified in the Charter Notice associated with such Redemption Failure) to

such Put Option has been exercised, and (ii) the Class A Preferred Return Amount
in respect of such Class A Preferred Units.

                      (b) At each Put Closing, (a) Allen or his designee shall
pay to the Holder (for itself and on behalf of its Permitted Transferees, if
applicable) the sum of the Put Purchase Price and the Interest Payment, if any,
in immediately available funds by wire transfer or certified bank check; and (b)

effective as of the last day of the calendar quarter following the date on which
the Holder delivers the Charter Notice; provided, however, that the Put Closing,
which shall be held at the offices of Irell & Manella in Los Angeles,
California, shall occur on the later of (i) the date that the Redemption Closing
was to have occurred but for the Redemption Failure, and (ii) five (5) business
days after the date on which the Allen Notice was delivered (or at such other

shall pay to Holder the Interest Payment. The Holder and Allen will cooperate so
as to permit all documents required to be delivered at the Put Closing to be
delivered by mail, delivery service or courier without requiring either party or
its representatives to be physically present at the Put Closing.

        8. Adjustment for Exchange, Reorganizations, Stock Splits, etc.

               8.1 If the Class A Preferred Units are increased, decreased,
changed into, or exchanged for a different number or kind of shares or
securities of Charter LLC through reorganization, recapitalization,
reclassification, dividend, split or reverse split, or other similar
transaction, an appropriate adjustment shall be made with respect to number and
kind of shares or securities subject to the Redemption Election and Put Option,
without change in the total price applicable to the unexercised portion of the
Redemption Election and Put Option but with a corresponding adjustment in the
price for unit of any security covered by the Redemption Election and Put

and Put Option pursuant to this Section 8.1 shall constitute "Issued Units" for
purposes of this Agreement.

"Business Combination") pursuant to which the outstanding Class A Preferred
Units are converted into or exchanged for any other security ("Replacement
Securities"), the Redemption Election and Put Option shall cease to be
exercisable with respect to the securities that previously constituted "Issued
Units" and shall instead be automatically converted into an option to sell such
number of shares or units of Replacement Securities issued in exchange for the
Issued Units pursuant to such Business Combination at a price per share or unit
of Replacement Securities equal to the aggregate Redemption Purchase Price for
all Issued Units immediately prior to such effectiveness divided

                                      -5-

<PAGE>   6
by the number of shares or units of Replacement Securities subject to the
Redemption Election immediately following such effectiveness. Any Replacement
Securities that become subject to the Redemption Election pursuant to this
Section 8.2 shall constitute "Issued Units" for purposes of this Agreement.

               8.3 In the event of any proposed Business Combination pursuant to
which the outstanding Class A Preferred Units will be converted into a right to
receive consideration other than securities of Charter LLC or Replacement
Securities, (i) Charter LLC will provide notice thereof to the Holder at least
ten (10) days prior to consummation of such Business Combination and (ii) the
Redemption Election and Put Option will expire two days prior to such
consummation except with respect to any Issued Units that are specified in a
Charter Notice delivered by the Holder pursuant to Section 2 prior to such date.
If the Holder delivers a Charter Notice after its receipt of a notice from
Charter LLC pursuant to this Section 8.3, the purchase and sale of any of the
Issued Units specified in the Holder's notice may be conditioned at the Holder's
option on the consummation of the Business Combination described in Charter
LLC's notice pursuant to this Section 8.3.

        9. Termination of Redemption Election and Put Option.

with CCI's initial public offering and pursuant to an agreement between Holder
and CCI; and

                      (c) the date specified in Section 8.3.

               9.2 The Redemption Election and Put Option shall terminate as to
any Issued Units on the date on which such Issued Units are first transferred by
the Holder or any Permitted Transferee to a person or entity that is not a
"Permitted Transferee."

        10. Miscellaneous.

               10.1 Complete Agreement; Modifications. This Agreement

                            ACCRETION PUT AGREEMENT

        This Accretion Put Agreement ("Agreement") is made as of the 12th day of
November, 1999, by and between Paul G. Allen, an individual ("Allen"), and
__________ (the "Holder"), with reference to the following facts:

        A Charter Communications Operating, LLC ("CCO") is a party to (1) that
certain Purchase and Sale Agreement by and among the persons or entities listed
on the signature pages thereto as "Sellers," and Rifkin Acquisition Partners,
L.L.L.P. ("RAP"), dated April 26, 1999 (the "RAP Agreement"), and (2) that
certain Purchase and Sale Agreement by and among the persons or entities listed
on the signature pages thereto as "Sellers," and InterLink Communications
Partners, LLLP ("InterLink"), dated April 26, 1999 (the "InterLink Agreement"
and, together with the RAP Agreement, the "Purchase Agreements"), pursuant to
which CCO and certain of its affiliates have acquired all of the outstanding
equity of RAP and InterLink, respectively.

        B Allen is the indirect controlling owner of CCO and expects to derive
benefit from the transactions contemplated by the Purchase Agreements.

        C Holder is a former owner of interests in RAP and/or InterLink and, in
connection with the transaction by which CCO acquired RAP and InterLink, and

pursuant to the Contribution Agreement (as defined below), Holder was issued
preferred membership units of Charter Communications Holding Company, LLC
("Charter LLC").

        D In connection with the initial public offering of Charter
Communications, Inc. ("CCI"), Holder exchanged its preferred membership units in
Charter LLC for CCI Stock (as defined below), and as a condition of such
exchange, Allen agreed to enter into this Agreement, giving Holder certain
rights with respect to the CCI Stock.

        NOW, THEREFORE, in consideration of the respective covenants and
agreements of the parties and for other good and valuable consideration (the
receipt and sufficiency of which are hereby acknowledged by each party), the
parties hereby agree as follows:

        1. Definitions. As used in this Agreement, the following terms have the
following meanings:

        "Closing Price" means, with respect to a share of CCI common stock, (i)
the last reported sales price, regular way, as reported on the principal
national securities exchange on which shares of CCI common stock are listed or
admitted for trading or (ii) if shares of CCI common stock are not listed or
admitted for trading on any national securities exchange, the last reported
sales price, regular way, as reported on the Nasdaq National Market or, in the
absence of any last reported sales price, the average of the highest bid and
lowest asked prices as reported on the Nasdaq Stock Market.

        "CCI Stock" means all shares of common stock of CCI issued to Holder in
exchange for preferred membership units of Charter LLC, and all other securities
that constitute "CCI Stock" in accordance with Section 5 of this Agreement.




<PAGE>   2
        "Contribution Agreement" means the Contribution Agreement dated as of
September 14, 1999, by and among, CCO, Charter Communications Holding Company,
LLC, the Investors, CCI and Allen, as amended by the First Amendment to
Contribution dated as of November 12, 1999.

        "IPO Price" means the price per share at which shares of common stock of
CCI are sold to the public in CCI's initial public offering (without reduction
for underwriters' fees, discounts, commissions, and other selling expenses).

        "Lockup Agreement" means the agreement entered into between the Holder
and the underwriters of CCI's initial public offering, which, among other
things, prohibits the Holder from selling the CCI Stock until the Lockup
Termination Date.

        "Lockup Termination Date" means the earliest date on which the Lockup
Agreement no longer prohibits the Holder from selling the CCI Stock.

        "Minimum Amount" means the lesser of (i) CCI Stock for which the
Purchase Price under this Agreement is at least $1,000,000, or (ii) all CCI
Stock that is subject to the Holder's Put Option under this Agreement.

        2. Put Option. Allen hereby grants to the Holder the right and option
(the "Put Option"), exercisable from the date hereof through and including the
date of termination of the Put Option under Section 7 by written notice
delivered to Allen, to sell and to permit any of the Holder's Permitted
Transferees to sell to Allen or his designee, from time to time, on one or more
occasions, all or any portion of the CCI Stock held by the Holder and its
Permitted Transferees that represents at least the Minimum Amount. Upon the
giving of such notice, Allen shall be obligated to buy or to cause his designee
to buy and, subject to Section 5.3, the Holder and the Permitted Transferees
identified in the Holder's notice pursuant to this Section 2 shall be obligated
to sell, the amount of the CCI Stock held by the Holder and its Permitted
Transferees that is specified in the Holder's notice pursuant to this Section 2,
at the price and upon the terms and conditions specified in Section 3.

        3. Purchase Price; Closing.

               3.1 The purchase price to be paid upon any exercise of the Put
Option (the "Purchase Price") shall be equal the IPO Price (calculated in
accordance with Section 5, if applicable), plus interest thereon at a rate of
four and one-half percent (4.5%) per year, compounded annually, for the period
from the date of this Agreement through the closing of the purchase and sale of
the CCI Stock hereunder (the "Closing").

               3.2 At each Closing, (a) Allen or his designee shall pay to the
Holder (for itself and on behalf of its Permitted Transferees, if applicable)
the Purchase Price in immediately available funds by wire transfer (if wire
transfer instructions were provided in the notice of exercise) or certified bank
check; and (b) the Holder shall deliver or cause to be delivered to Allen or his
designee one or more certificates evidencing the CCI Stock to be purchased and
sold at such Closing, together with duly executed assignments separate from the
certificate in form and substance reasonably acceptable to Allen to effectuate
the transfer of such CCI Stock to


                                      -2-

<PAGE>   3
Allen or his designee, together with a certificate of the Holder and its
Permitted Transferee, if applicable, reaffirming the representations in Section
4.

               3.3 Each Closing shall be held at the offices of Irell & Manella
in Los Angeles, California, on (or before if Allen so determines) the thirtieth
day after the Holder delivers the written notice described above (or, if such
day is not a business day, on the next business day thereafter), or at such
other time and place as the Holder and Allen may agree. The Holder and Allen
will cooperate so as to permit all documents required to be delivered at the
Closing to be delivered by mail, delivery service or courier without requiring
either party or his or its representatives to be physically present at the
Closing.

        4. Representations of the Holder. The Holder represents and warrants to
Allen and any of his designees or assignees that on the date hereof and at each
Closing: (a) the Holder has full power and authority to execute and deliver this
Agreement and consummate the transactions contemplated hereby; (b) this
Agreement is the legal, valid and binding obligation of the Holder, enforceable
against the Holder in accordance with its terms; (c) at each Closing, the Holder
or one of its Permitted Transferees will own all of the CCI Stock required to be
purchased and sold at such Closing, both of record and beneficially, free and
clear of all liens, encumbrances or adverse interests of any kind or nature
whatsoever (including any restriction on the right to vote, sell or otherwise
dispose of the CCI Stock), other than those arising under applicable law and
those arising under the organizational documents of CCI; (d) upon the transfer
of the CCI Stock pursuant to Section 3, Allen or his designee will receive good
title to the CCI Stock, free and clear of all liens, encumbrances and adverse
interests created by the Holder, any Permitted Transferee, or any of their
respective predecessors-in-interest, other than those arising under applicable
law or those arising under the organizational documents of CCI.

        5. Adjustment for Exchange, Reorganizations, Stock Splits, etc.

               5.1 If the number of shares of CCI Stock is increased, decreased,
changed into, or exchanged for a different number or kind of shares or
securities of CCI through reorganization, recapitalization, reclassification,
stock dividend, stock split or reverse stock split, or other similar
transaction, an appropriate adjustment shall be made with respect to number and
kind of shares or securities subject to the Put Option, without change in the
total price applicable to the unexercised portion of the Put Option but with a
corresponding adjustment in the price per unit of any security covered by the
Put Option. Any shares or securities that become subject to the Put Option
pursuant to this Section 5.1 shall constitute "CCI Stock" for purposes of this
Agreement.

               5.2 Upon a reorganization, merger or consolidation of CCI with
one or more other corporations or entities (any of the foregoing, a "Business
Combination") pursuant to which the outstanding CCI Stock is converted into or
exchanged for any other security ("Replacement Securities"), the Put Option
shall cease to be exercisable with respect to the securities that previously
constituted "CCI Stock" and shall instead be automatically converted into an
option to sell such number of shares or units of Replacement Securities issued
in exchange for the CCI Stock pursuant to such Business Combination at a price
per share or unit of Replacement Securities equal to the aggregate Purchase
Price for all CCI Stock immediately prior to such effectiveness divided by the
number of shares or units of Replacement Securities subject to the


                                      -3-



<PAGE>   4
Put Option immediately following such effectiveness. Any Replacement Securities
that become subject to the Put Option pursuant to this Section 5.2 shall
constitute "CCI Stock" for purposes of this Agreement.

               5.3 In the event of any proposed Business Combination pursuant to
which the outstanding CCI Stock will be converted into a right to receive
consideration other than securities of CCI or Replacement Securities, (i) Allen
will provide notice thereof to the Holder at least ten (10) days prior to
consummation of such Business Combination and (ii) the Put Option will expire
two days prior to such consummation except with respect to any CCI Stock that is
specified in a notice delivered by the Holder pursuant to Section 2 prior to
such date. If the Holder delivers a notice pursuant to Section 2 after its
receipt of a notice from Allen pursuant to this Section 5.3, the purchase and
sale of any of the CCI Stock specified in the Holder's notice may be conditioned
at the Holder's option on the consummation of the Business Combination described
in Allen's notice pursuant to this Section 5.3.

        6. Representations of Allen. Allen represents and warrants to the Holder
and each Permitted Transferee that on the date hereof and at all times hereafter
through the Closing: (a) Allen has full power and authority to execute and
deliver this Agreement and consummate the transactions contemplated hereby; (b)
this Agreement constitutes the legal, valid and binding obligation of Allen,
enforceable against Allen in accordance with its terms; (c) his execution and
delivery of this Agreement does not, and his performance of his obligations
under this Agreement will not, violate, conflict with or constitute a breach of,
or a default under, any material agreement, indenture or instrument to which he
is a party or which is binding on him, and will not result in the creation of
any lien on, or security interest in, any of his assets (other than such
violations, breaches, defaults, liens or security interests that would not
materially and adversely affect his ability to perform his obligations under
this Agreement); and (d) his Net Worth is and will be greater than $4 billion.
At the request of R&A Management, LLC, a Colorado limited liability company
("R&A"), made (on behalf of Holder together with all other holders receiving put
agreements in connection with the transactions under the Purchase Agreements) no
more frequently than once every 180 days, Allen will within 10 days of such
request deliver to R&A a certificate signed by him or his attorney-in-fact as to
the representation and warranty in clause (d) being true and correct at such
time. "Net Worth" means the excess of the fair market value of Allen's assets
over the aggregate amount of Allen's liabilities.

        7. Termination of Put Option.

               7.1 The Put Option shall terminate on the earliest of the
following dates, except with respect to any CCI Stock that is specified in a
notice delivered by the Holder pursuant to Section 2 prior to such earliest
date:

                      (a) the later of (x) thirty days after the Lockup
Termination Date, or (y) the second anniversary of the date of this Agreement;

                      (b) the date specified in Section 5.3; and

                      (c) the later of (x) thirty days after the Lockup
Termination Date, or (y) the first date on which both of the following
conditions are satisfied:

<PAGE>   5
                             (i) the Closing Price of CCI common stock has
exceeded 115% of the IPO Price for any 90 trading days during the preceding 100
consecutive trading days; and

                             (ii) all shares of CCI common stock then held by
the Holder or any Permitted Transferee (as defined below) and subject to the Put
Option may be sold to the public in their entirety on such date (x) without
registration under the Securities Act of 1933, as amended (the "Act"), pursuant
to Rule 144 under the Act or another comparable provision or (y) pursuant to a
then effective registration statement under the Act.

               7.2 The Put Option shall terminate as to any CCI Stock on the
date on which such CCI Stock is first transferred by the Holder or any Permitted
Transferee to a person or entity that is not a "Permitted Transferee."

               7.3 For purposes of determining whether the condition in Section
7.1(c)(i) is satisfied, appropriate adjustments will be made to take into
account any subdivision (by stock split or otherwise) or combination (by reverse
stock split or otherwise) of outstanding shares of CCI common stock occurring
after the consummation of CCI's initial public offering.

        8. Miscellaneous.

Agreement is the legal, valid and binding obligation of the Holder, enforceable
against the Holder in accordance with its terms; (c) at each Closing, the Holder
or one of its Permitted Transferees will own all of the CCI Stock required to be

those arising under the organizational documents of CCI; (d) upon the transfer
of the CCI Stock pursuant to Section 3, Allen or his designee will receive good

shares or securities of CCI through reorganization, recapitalization,
reclassification, stock dividend, stock split or reverse stock split, or other
similar transaction, an appropriate adjustment shall be made with respect to
number and kind of shares or securities subject to the Put Option. Any shares or
securities that become subject to the Put Option pursuant to this Section 5.1
shall constitute "CCI Stock" for purposes of this Agreement.

               5.2 Upon a reorganization, merger or consolidation of CCI with
one or more other corporations or entities (any of the foregoing, a "Business

exchanged in whole or in part for any other publicly-traded security
("Replacement Securities"), the Put Option shall cease to be exercisable with
respect to the securities that previously constituted "CCI Stock" and shall
instead be automatically converted into an option to sell such number of shares
or units of Replacement Securities issued in exchange for the CCI Stock pursuant
to such Business Combination at a price per share or unit of Replacement
Securities equal to the aggregate Purchase Price for all CCI Stock immediately
prior to such effectiveness divided by the number of shares or units of
Replacement Securities subject to the Put Option immediately following such
effectiveness. Any Replacement Securities that become subject to the Put Option
pursuant to this Section 5.2 shall constitute "CCI Stock" for purposes of this
Agreement.

               5.3 In the event of any proposed Business Combination pursuant to
which the outstanding CCI Stock will be converted in whole or in part into a
right to receive consideration other than publicly-traded securities of CCI or
Replacement Securities, (i) Allen will provide notice thereof to the Holder at
least ten (10) days prior to consummation of such Business

consummation except with respect to any CCI Stock that is specified in a notice
delivered by the Holder pursuant to Section 2 prior to such date and except to
the extent the Put Option will continue under 5.2 as to that portion of the
consideration received constituting Replacement Securities. If the Holder
delivers a notice pursuant to Section 2 after its receipt of a notice from Allen
pursuant to this Section 5.3, the purchase and sale of any of the CCI Stock
specified in the Holder's notice may be conditioned at the Holder's option on
the consummation of the Business Combination described in Allen's notice
pursuant to this Section 5.3.

and each Permitted Transferee that on the date hereof and at all times hereafter

deliver this Agreement and consummate the transactions contemplated hereby; (b)
this Agreement constitutes the legal, valid and binding obligation of Allen,

or a default under, any material agreement, indenture or instrument to which he
is a party or which is binding on him, and will not result in the creation of
any lien on, or security interest in, any of his assets (other than such
violations, breaches, defaults, liens or security interests that would not

this Agreement); and (d) his Net Worth is and will be greater than $4 billion.

incorporated on July
 22, 1999 ("PublicCo"), in exchange for shares of PublicCo's
Class A Common Stock.

        C. Under Section 3.6.6 of the Amended and Restated Limited Liability
Company Agreement of Charter LLC, dated as of November 12, 1999 (the "LLC
Agreement"), Charter LLC may issue to PublicCo, as transferee of the Holder with
respect to the Class D Common Units assigned to PublicCo by the Holder pursuant
to the Exchange Agreement, additional Common Units. Pursuant to the Exchange
Agreement, PublicCo or its successor will issue additional shares of Class A
Common Stock or other securities to the Holder if Charter LLC issues additional
Common Units to PublicCo in accordance with Section 3.6.6 of the LLC Agreement.

        D. As an inducement for FHGLP to enter into the Purchase and
Contribution Agreement, Charter agreed that Allen would grant the Holder the Put
Option provided for herein.

        NOW, THEREFORE, in consideration of the respective covenants and
agreements of the parties and for other good and valuable consideration (the
receipt and sufficiency of which are hereby acknowledged by each party), the
parties hereby agree as follows:

        1. Definitions. As used in this Agreement, the following terms have the
following meanings:

        "Closing Price" means, with respect to a share of PublicCo common stock,
(i) the last reported sales price, regular way, as reported on the principal
national securities exchange on which shares of PublicCo common stock are listed
or admitted for trading or (ii) if shares of PublicCo common stock are not
listed or admitted for trading on any national securities exchange, the last
reported sales price, regular way, as reported on the Nasdaq National Market or,
if shares of PublicCo common stock are not listed on the Nasdaq National Market,
the average of the highest bid and lowest asked prices as reported on the Nasdaq
Stock Market.




<PAGE>   2
        "Exchange Agreement" means the Exchange Agreement, dated as of November
12, 1999, among PublicCo, the Holder, and other partners of FHGLP.

        "Issuer" means the issuer of the Shares.

        "Minimum Amount" means the least of (i) Shares for which the Purchase
Price under this Agreement is at least $50,000,000, (ii) Shares representing at
least 50% of the equity represented by all shares of PublicCo common stock
acquired by the Holder pursuant to the Exchange Agreement, or (iii) all Shares
that are subject to the Holder's Put Option under this Agreement.

        "Shares" means any shares of Class A Common Stock of PublicCo issued
pursuant to the Exchange Agreement (including any shares subsequently issued
pursuant to Section 2.5 of the Exchange Agreement), and any other securities of
PublicCo or its successors that are issued pursuant to Section 2.5 of the
Exchange Agreement, and all other securities that constitute "Shares" in
accordance with Section 5 of this Agreement.

        2. Put Option. Allen hereby grants to the Holder the right and option
(the "Put Option"), exercisable from the date hereof through and including the
date of termination of the Put Option under Section 7 by written notice
delivered to Allen, to sell and to permit any of the Holder's Permitted
Transferees to sell to Allen or his designee, from time to time, on one or more
occasions, all or any portion of the Shares held by the Holder and its Permitted
Transferees that represents at least the Minimum Amount. Upon the giving of such
notice, Allen shall be obligated to buy or to cause his designee to buy and,
subject to Section 5.4, the Holder and the Permitted Transferees identified in
the Holder's notice pursuant to this Section 2 shall be obligated to sell, the
amount of the Shares held by the Holder and its Permitted Transferees that is
specified in the Holder's notice pursuant to this Section 2, at the price and
upon the terms and conditions specified in Section 3.

        3. Purchase Price; Closing.

               3.1 The purchase price to be paid upon any exercise of the Put
Option (the "Purchase Price") shall be equal to $26.7235 per share of PublicCo
common stock represented by the Shares to be purchased and sold (calculated in
accordance with Section 5, if applicable), plus interest thereon at a rate of
four and one-half percent (4.5%) per year, compounded annually, for the period
from the date of the closing under the Purchase and Contribution Agreement
through the closing of the purchase and sale of the Shares hereunder (the
"Closing").

               3.2 At each Closing, (a) Allen or his designee shall pay to the
Holder (for itself and on behalf of its Permitted Transferees, if applicable)
the Purchase Price in immediately available funds by wire transfer or certified
bank check; and (b) the Holder shall deliver or cause to be delivered to Allen
or his designee one or more certificates evidencing the Shares to be purchased
and sold at such Closing (if such Shares are certificated securities), together
with duly executed assignments separate from certificate in form and substance
sufficient to effectuate the transfer of such Shares to Allen or his designee,
together with a certificate of the Holder and its Permitted Transferee, if
applicable, reaffirming the representations in Section 4; provided, however,
that neither the Holder nor any Permitted Transferee shall be required to take
any



                                      -2-

<PAGE>   3
actions or deliver any documents to satisfy any restrictions imposed by the
Issuer on the transfer of the Shares, and provided, further, that, if the Holder
is unable to deliver certificates evidencing the Shares to be purchased and sold
at such Closing because PublicCo failed to deliver such certificates to the
Holder within the period specified in the Exchange Agreement, then, in lieu of
delivering such certificates to Allen at the Closing, the Holder will deliver to
Allen at the Closing its undertaking to deliver such certificates to Allen as
soon as practicable after it receives them from PublicCo.

               3.3 Each Closing shall be held at the offices of Irell & Manella
in Los Angeles, California, on the tenth business day after the Holder delivers
the written notice described above, or at such other time and place as the
Holder and Allen may agree. The Holder and Allen will cooperate so as to permit
all documents required to be delivered at the Closing to be delivered by mail,
delivery service or courier without requiring either party or his or its
representatives to be physically present at the Closing.

               3.4 If, at any time after the Holder has sold any Shares to Allen
or his designee pursuant to the Put Option provided in this Agreement, Charter
LLC issues additional Common Units to PublicCo or its successor pursuant to
Section 3.6.6 of the LLC Agreement and, as a result thereof, PublicCo or its
successor issues additional shares of common stock or other securities to the
Holder or its successor pursuant to Section 2.5 of the Exchange Agreement, then
the Holder agrees to assign to Allen or his designee, without additional
consideration, that portion of the additional shares of common stock or other
securities issued to the Holder or its successor equal to a fraction the
numerator of which is the number of shares of PublicCo common stock on the date
of this Agreement that were represented by the Shares that were sold by the
Holder to Allen or his designee pursuant to the Put Option and the denominator
of which is the number of shares of PublicCo common stock on the date of this
Agreement that were originally issued to the Holder under the Exchange Agreement
and subject to this Put Option.

        4. Representations of the Holder. The Holder represents and warrants to
Allen and any of his designees or assignees that on the date hereof and at each
Closing: (a) the Holder has full power and authority to execute and deliver this
Agreement and consummate the transactions contemplated hereby; (b) this
Agreement is the legal, valid and binding obligation of the Holder, enforceable
against the Holder in accordance with its terms; (c) at each Closing, the Holder
or one of its Permitted Transferees will own all of the Shares required to be
purchased and sold at such Closing, both of record and beneficially, free and
clear of all liens, encumbrances or adverse interests of any kind or nature
whatsoever (including any restriction on the right to vote, sell or otherwise
dispose of the Shares), other than those arising under applicable law and those
arising under the organizational documents of the Issuer; (d) upon the transfer
of the Shares pursuant to Section 3, Allen or his designee will receive good
title to the Shares, free and clear of all liens, encumbrances and adverse
interests created by the Holder, any Permitted Transferee, or any of their
respective predecessors-in-interest, other than those arising under applicable
law or those arising under the organizational documents of the Issuer.

        5. Adjustment for Exchange, Reorganizations, Stock Splits, etc.

               5.1 If, at any time during which the Holder continues to hold any
Shares that are subject to the Put Option provided in this Agreement, Charter
LLC issues additional Common Units to PublicCo or its successor pursuant to
Section 3.6.6 of the LLC Agreement and, as a result thereof, PublicCo or its
successor issues additional shares of common stock or other securities to the
Holder or its successor pursuant to Section 2.5 of the Exchange Agreement, then,
with respect to any Shares held by the Holder at the time such additional shares
or other securities are issued, the price per share specified in Section 3.1
shall be reduced so as to equal the product of the price per share specified in
Section 3.1 times a fraction the numerator of which is 20,581,117 and the
denominator of which is the sum of 20,581,117 plus the total number of
additional Common Units issued to PublicCo pursuant to Section 3.6.6 of the LLC
Agreement at any time after the date of this Agreement (adjusted to reverse the
effect of any reorganization, recapitalization, reclassification, dividend of
Common Units, split or reverse split, or other similar transaction affecting the
number of outstanding Common Units that may have occurred between the date of
this Agreement and the date any such additional Common Units were issued to
PublicCo).

               5.2 If the Shares are increased, decreased, changed into, or
exchanged for a different number or kind of shares or securities of the Issuer
through reorganization, recapitalization, reclassification, stock dividend,
stock split or reverse stock split, or other similar transaction, an appropriate
adjustment shall be made with respect to number and kind of shares or securities
subject to the Put Option, without change in the total price applicable to the
unexercised portion of the Put Option but with a corresponding adjustment in the
price per unit of any security covered by the Put Option. Any shares or
securities that become subject to the Put Option pursuant to this Section 5.2
shall constitute "Shares" for purposes of this Agreement.

               5.3 Upon a reorganization, merger or consolidation of the Issuer
with one or more other corporations or entities (any of the foregoing, a
"Business Combination") pursuant to which the outstanding Shares are converted
into or exchanged for any other security ("Replacement Securities"), the Put
Option shall cease to be exercisable with respect to the securities that
previously constituted "Shares" and shall instead be automatically converted
into an option to sell such number of shares or units of Replacement Securities
issued in exchange for the Shares pursuant to such Business Combination at a
price per share or unit of Replacement Securities equal to the aggregate
Purchase Price for all Shares immediately prior to such effectiveness divided by
the number of shares or units of Replacement Securities subject to the Put
Option immediately following such effectiveness. Any Replacement Securities that
become subject to the Put Option pursuant to this Section 5.3 shall constitute
"Shares" for purposes of this Agreement.

               5.4 In the event of any proposed Business Combination pursuant to
which the outstanding Shares will be converted into a right to receive
consideration other than securities of the Issuer or Replacement Securities, (i)
Allen will provide notice thereof to the Holder at least ten (10) days prior to
consummation of such Business Combination and (ii) the Put Option will expire
two days prior to such consummation except with respect to any Shares that are
specified in a notice delivered by the Holder pursuant to Section 2 prior to
such date. If the Holder delivers a notice pursuant to Section 2 after its
receipt of a notice from Allen pursuant to this


                                      -4-

<PAGE>   5
Section 5.4, the purchase and sale of any of the Shares specified in the
Holder's notice may be conditioned at the Holder's option on the consummation of
the Business Combination described in Allen's notice pursuant to this Section
5.4.

        6. Representations of Allen. Allen represents and warrants to the Holder
and each Permitted Transferee that on the date hereof and at all times hereafter
through the Closing: (a) Allen has full power and authority to execute and
deliver this Agreement and consummate the transactions contemplated hereby; and
(b) this Agreement constitutes the legal, valid and binding obligation of Allen,
enforceable against Allen in accordance with its terms.

        7. Termination of Put Option.

               7.1 The Put Option shall terminate on the earliest of the
following dates, except with respect to any Shares that are specified in a
notice delivered by the Holder pursuant to Section 2 prior to such earliest
date:

                      (a) the second anniversary of the date of the closing
under the Purchase and Contribution Agreement;

                      (b) the date specified in Section 5.4; and

                      (c) the first date on which both of the following
conditions are satisfied:

                             (i) the Closing Price of PublicCo common stock has
exceeded $21.85 for any 90 trading days during the preceding 100 consecutive
trading days (which period of 100 trading days shall not have commenced prior to
the closing under the Purchase and Contribution Agreement); and

                             (ii) all shares of PublicCo common stock then held
by the Holder and subject to the Put Option may be sold to the public in their
entirety on such date (x) without registration under the Securities Act of 1933,
as amended (the "Act"), pursuant to Rule 144 under the Act or another comparable
provision or (y) pursuant to a then effective registration statement under the
Act.

               7.2 The Put Option shall terminate as to any Shares on the date
on which such Shares are first transferred by the Holder or any Permitted
Transferee to a person or entity that is not a "Permitted Transferee."

               7.3 For purposes of determining whether the condition in Section
7.1(c)(i) is satisfied, appropriate adjustments will be made to take into
account any subdivision (by stock split or otherwise) or combination (by reverse
stock split or otherwise) of outstanding shares of PublicCo common stock
occurring after the consummation of PublicCo's initial public offering.

not Transfer any Shares now or hereafter at any time owned by such Manager to
the extent prohibited by this Agreement. The Company will not transfer upon its
books any Shares to any Person to the extent prohibited by this Agreement and
any purported transfer in violation hereof will be null and void and of no
effect.

2.2  Right of First Refusal.

        2.2.1 Except for Permitted Transfers, no Manager will Transfer all or
        any portion of his Shares in any manner whatsoever, unless he first
        gives written notice (the "Notice") of the proposed Transfer to Allen.
        The Notice will name the proposed Transferee, specify the type and
        number of Shares to be transferred, the price (as agreed and also, if
        different, stated in U.S. Dollars) to be paid for them, and the other
        material terms of the proposed Transfer. The Notice will also constitute
        an offer to sell the pertinent Shares to Allen on the terms described
        therein. To the extent that the consideration proposed to be paid by any
        transferee involves non-cash consideration, Allen may pay an equivalent
        value in cash should he choose to accept his right of first refusal.

        2.2.2 If, within 30 days following the giving of the Notice, Allen gives
        a written notice (the "ELECTION NOTICE") to the transferring Manager of
        his acceptance of the offer set forth in the Notice, the Manager shall
        sell all, but not less than all of such Shares to Allen.

        2.2.3 Upon expiration of the period for giving of the Election Notice
        (without notice having been given), then all, but not less than all, of
        the Shares included in the Notice may be transferred to the proposed
        Transferee at any time within 90 days following the expiration of that
        period, at a price and on terms no more favorable to the Transferee than
        those specified in the Notice. Any later proposed Transfer may be made
        (if otherwise permissible) only by again following the procedures
        specified in this Section 2.2.

        2.2.4 The closing of any purchase and sale made by Allen, upon exercise
        of his rights under this Section 2.2, will be held within 60 days
        following the giving of the Election Notice, at the then principal
        offices of the Company or such other place as


                                      -3-

<PAGE>   4
        is agreed upon by the parties to that closing. The purchase price in
        such a purchase and sale will be a cash amount equal to the price
        specified in the Notice, paid by certified check, bank draft or wire
        transfer payable to the order of the transferring Manager (or his
        Permitted Transferees), against the transferring Manager's delivery to
        Allen of certificates representing the Shares to be transferred, which
        will be free and clear of all liens and encumbrances and duly endorsed
        for transfer or accompanied by duly executed stock powers.

2.3 Agreement to be Bound. No Transfer of Shares will be effective (and the
Company will not transfer on its books any Shares) unless (a) the certificates
representing such Shares issued to the Transferee bear the legends required by
Section 8.4, and (b) the Transferee has executed and delivered to the Company,
as a condition precedent to such Transfer, an instrument or instruments in form
and substance satisfactory to the Company, confirming that Transferee (and the
Transferee's spouse if such spouse will receive a community property interest in
the Shares) agrees to be bound by the terms of this Agreement (including without
limitation the provisions of Section 2.2 applicable to the Managers); provided,
however, that the condition set forth in clause (a) of this Section 2.3 will not
apply to any sale of Shares to the public pursuant to an effective registration
statement under the Securities Act or, provided such sale is not to an Affiliate
of the Selling Stockholder, pursuant to Rule 144 promulgated under the Act.

2.4 Involuntary Transfers. In the case of any Transfer of title or beneficial
ownership of Shares upon default, foreclosure, forfeit, court order, or
otherwise than by a voluntary decision on the part of a Stockholder, other than
the death of a Stockholder (an "INVOLUNTARY TRANSFER"), such Stockholder will
promptly (but in no event later than 30 days after such Involuntary Transfer)
furnish written notice to the Company indicating that the Involuntary Transfer
has occurred, specifying the name of the person to whom such Shares have been
transferred, giving a detailed description of the circumstances giving rise to,
and stating the legal basis for, the Involuntary Transfer. In the event of any
such Involuntary Transfer, the Company will have the right, exercisable at any
time within 60 days of the date it receives notice of such Involuntary Transfer,
to purchase such Shares for their fair market value as determined under Section
5.4.

3.      TAG ALONG RIGHTS.

3.1 Rights to Participate in Sale. In the event that a Stockholder (the
"PROPOSED Transferor") accepts a bona fide offer pursuant to which Shares are
being sold to any person or persons acting in concert (the "PROPOSED
TRANSFEREE") in a transaction or series of transactions which will result in a
transfer of 25% or more of the outstanding Common Stock (a "TAG ALONG SALE"),
each of the other Stockholders (the "OTHER STOCKHOLDERS") shall have the right
and option to participate (the "TAG ALONG RIGHT"), prior to any such sale by the
Proposed Transferor, in such sale in the manner and to the extent provided in
this Section 3. Upon the acceptance of a bona fide offer by the Proposed
Transferor, the Proposed Transferor shall promptly give notice (the "TAG ALONG
NOTICE") to each of the Other Stockholders of the Tag Along Right, and shall
attach a copy of the bona fide offer. To exercise the Tag Along Right, each of
the Other Stockholders shall deliver written notice to such effect to the
Proposed Transferor and Proposed Transferee within 10 days next



                                      -4-

<PAGE>   5
following receipt by the Other Stockholders, as the case may be, of notice of
the Tag Along Right.

3.2 Shares Covered. If any Stockholder exercises his Tag Along Right under this
Section 3, he shall be entitled to cause to be included in such sale up to the
number of Shares held by him multiplied by a fraction the numerator of which
equals the total number of shares being sold in such sale and the denominator of
which equals the total number of shares of Common Stock outstanding. The
purchase price for each Share subject to Tag Along Sale, and all other terms of
such sale (including representations, warranties and indemnity obligations on a
pro rata basis), shall be the same as are applicable to the Proposed Transferor.

3.3 Delivery of Certificates. On the closing date of Tag-Along Sale each
Stockholder who has exercised its Tag Along Right shall deliver a certificate or
certificates for all of its Shares being transferred, duly endorsed for transfer
with signatures guaranteed, to the Proposed Transferee in the manner and at the
address indicated in the Tag-Along Notice in exchange for payment of the
purchase price for such Shares.

3.4  Exempt Transfers.  The provisions of this Section 3 will not apply:

        3.4.1 to any sale or other disposition for value to any Permitted
        Transferee or other Affiliate of Allen; or

        3.4.2 to any sale of Shares by Allen (or an Affiliate) to the public
        pursuant to an effective registration statement under the Securities Act
        or pursuant to Rule 144.

4.      DRAG-ALONG SALES.

4.1 Right to Require Sale. In the event that Allen and/or his Affiliates accept
a bona fide offer pursuant to which Shares are being sold to a Proposed
Transferee and as a result of such sale (after giving effect to the inclusion of
the other Stockholders' Shares as required under this Section 4) the Proposed
Transferee would own fifty percent (50%) or more of the outstanding Common Stock
(any such transaction, a "DRAG-ALONG SALE"), then each other Stockholder hereby
agrees to sell to such Proposed Transferee, upon the demand of Allen, the same
percentage of the total number of Shares held by such Stockholder on the date of
the notice of the Drag-Along Sale as the number of Shares that Allen is
proposing to sell in the Drag-Along Sale represent out of the total Shares owned
by Allen on a fully diluted basis as of the date of the Drag-Along Notice at the
same price and on the same terms and conditions (including representations,
warranties and indemnity obligations on a pro rata basis) as Allen has agreed
with such Third Party. Allen shall make such demand by written notice (the "Drag
Along Notice) to the other Stockholders not less that 10 days prior to the
closing of the Drag Along Sale.

4.2 Delivery of Certificates. On the closing date of the Drag-Along Sale
specified in the Drag Along Notice, each other Stockholder will deliver a
certificate or certificates for the Shares subject to the Drag Along Sale, duly
endorsed for transfer with signatures guaranteed, to the Proposed Transferee in
the manner and at the address indicated in the


                                      -5-

<PAGE>   6
Drag Along Notice in exchange for payment of the purchase price for such Shares.

5.      PUT AND CALL RIGHTS.

5.1 Death and Disability. Upon the death or disability (a "Sale Event") of any
of Babcock, Kent or Wood, then Babcock, Kent or Wood, as applicable, or his
personal representative (such personal representative also being hereinafter
referred to as a "Stockholder"), shall be obligated to sell, and the Company
shall be obligated to buy, all of the Shares owned at the time of the Sale Event
by such Stockholder (and his related transferees, if any) at their fair market
value as set forth in Section 5.4 hereof. If the Company shall be unable or fail
for any reason (including, without limitation, by reason of legal or contractual
restrictions) to purchase all of the shares of Babcock, Kent and Wood, as
applicable, then Allen shall be obligated to purchase such shares which the
Company is unable or fails to purchase.

5.2 Termination of Employment. Upon the termination of Kent as Chief Executive
Officer of the Company for any reason whatsoever, including, but not limited to
death, disability or termination of employment by the Company, each of Kent,
Babcock or Wood shall have the right to sell to the Company, and the Company
shall have the obligation to purchase from each of them exercising such right,
all, but not less than all, of their respective Shares (and their related
transferees, if any) at their fair market value as set forth in Section 5.4
hereof, provided that if Kent's employment shall have terminated due to his
voluntary resignation without "Good Reason" or he shall have been terminated by
the company for "Cause" (as such terms are defined in his Employment Agreement)
or if he shall not agree to the continuation of his employment with the Employer
under his Employment Agreement, then the Company (or, at his election, Allen)
shall have the right to purchase, and each of Kent, Babcock or Wood shall have
the obligation to sell to the Company, all, but not less than all, of their
respective Shares (and their Permitted Transferees, if any) at fair market value
as set forth in Section 5.4 hereof. Any party wishing to exercise its rights
under this Section 5.2 shall do so by written notice to be delivered within 60
days following such termination, and such rights shall terminate upon expiration
of such 60 day period in the absence of such a notice. If the Company shall be
unable or fail for any reason (including, without limitation, by reason of legal
or contractual restrictions) to purchase all of such shares where required to do
so hereunder, then Allen shall be obligated to purchase such shares which the
Company is unable or fails to purchase.

5.3 Merger or Consolidation of the Company. In the event that the Company merges
or consolidates with or into another person or entity, the Managers will have
the right to sell to Allen, and Allen will have the obligation to purchase from
the Managers, all, but not less than all, of the Shares owned by them at their
fair market value as set forth in Section 5.4; provided, however, that this
Section 5.3 shall not apply to (i) any merger or consolidation following which
each of the Stockholders holds approximately the same proportionate interest in
the surviving entity as they held in the Company prior to such merger or
consolidation or (ii) a merger or consolidation with Marcus Cable Properties,
Inc. or any of its Affiliates.

5.4 Appraisal. The put price or the call price, as the case may be, shall be the
fair market value of the Stockholders' Shares on a fully diluted basis (treating
any stock appreciation


                                      -6-

<PAGE>   7
rights or equivalent rights as equity equivalents) as of the anticipated
purchase date by the Company pursuant to Sections 5.1 or 5.2, or the date of the
merger or consolidation of the Company pursuant to Section 5.3, as the case may
be (determined with no discount for minority interests, lack of marketability,
existence of rights of first refusal or other restrictions on transfer, blocking
rights, or lack of voting rights, and shall be determined by two nationally
recognized appraisal or investment banking firms with experience in appraising
companies in the cable television industry (each, an "Appraisal Firm"), one
selected by the Stockholder disposing of such shares, and one selected by the
Company. The Stockholders and the Company shall promptly notify each other of
their selections of Appraisal Firms within thirty (30) days of the Stockholders'
exercise of their put right or the Company's exercise of its call right. The
Appraisal Firms selected in accordance with the foregoing procedure shall submit
their determination of the put price or the call price, as the case may be, to
the Company and the Stockholders within (20) twenty days following the selection
of the second of such Appraisal Firms. The two Appraisal Firms shall endeavor in
good faith to reach agreement on the put price or the call price, as the case
may be, within such 20-day period. If the two Appraisal Firms so selected are
unable to agree upon a put price or a call price, as the case may be, within
such 20-day period, they shall jointly select a third Appraisal Firm which shall
determine the put price or the call price, as the case may be (which price shall
be between the prices initially determined by the initial two Appraisal Firms),
and which determination shall be final and binding. The costs of such appraisals
shall be borne by the Company.

2. Put Option.

        A. CII hereby grants to the Holder, effective six months after
consummation of the IPO and subject to the terms and conditions set forth
herein, the right and option (the "Put Option"), exercisable from time to time
on one or more occasions but no more frequently than four times each calendar
year by delivery of written notice to CII during the Put Period (as defined in
Section 9), to sell to CII or its designee, all or any portion of the Holder's
Common Stock (which may include Common Stock held by any Permitted Transferee of
such Holder) but not less than the Minimum Amount. Upon the giving of such
notice, subject to Section 5.B, CII shall be obligated to buy or to cause its
designee to buy, and the Holder shall be obligated to sell, the Holder's Common
Stock as to which the Put Option has been exercised, at the price and upon the
terms and conditions specified in Sections 3 and 4.

        B. In the event that CII or its designee is for any reason (other than

obligated to buy or to cause his

<PAGE>   3
designee to buy, and the Holder shall be obligated to sell, such Common Stock on
the terms and conditions applicable to CII in this Agreement.

3. Purchase Price.

        A. The purchase price per share of Common Stock to be paid upon the
exercise of the Put Option (the "Purchase Price") shall be equal to (1) the
Adjustment Amount (as defined in Section 3.C), if any, plus the product of (i)
the Holdco Unit Value (as defined below), and (ii) the number of Membership
Units held by CII, divided by (2) the total number of outstanding shares of
Common Stock, assuming the exercise of all options, warrants or other similar
rights held by any person to purchase Common Stock.

        B. The Holdco Unit Value shall be determined as follows:

               (i) The Holdco Unit Value shall equal the average of the highest
and lowest quoted selling prices of a share of CCI's Class A Common Stock on the
principal national securities exchange on which the Class A Common Stock of CCI
is listed or admitted to trading, or, if not so listed or admitted to trading,
as reported by the NASDAQ Stock Market's National Market, on each of the thirty
(30) trading days immediately preceding the date on which a put notice is given
(the "Share Value"), so long as all of the following are true:

                      a. Clause (b) of Article Third and Clauses (a)(ii) and
(b)(iii) of Article Fourth of CCI's Certificate of Incorporation as in effect on
the IPO Date continue to be in effect and have not amended so as to
substantively modify the provisions thereof, and CCI is in substantial
compliance with those provisions; and

                      b. Sections 3.5.4, 3.6.1, 3.6.4(d), 3.6.4(e) and 5.1.7 of
the LLC Agreement have not then been amended so as to substantively modify those
provisions in a manner that would alter the amount per Membership Unit that any
class of Common Units would be entitled to receive on liquidation of Charter
Holdco.

               (ii) If the conditions in Sections 3.B(i)a and 3.B(i)b are not
satisfied, then the Holdco Unit Value shall equal the fair market value of a
Common Unit held by CII, as determined in accordance with Section 2.3(b) of the
Exchange Agreement.

        C. So long as CII has no material outstanding liabilities (other than
obligations pursuant to options, warrants or other similar rights held by any
person to purchase common stock of CII) and no material assets other than its
Membership Units, the "Adjustment Amount" (as used in the calculation of the
Purchase Price) shall be zero. To the extent necessary to reflect any additional
liabilities or assets of CII, the Purchase Price will be equitably adjusted by
increasing the Adjustment Amount by the value of any material assets of CII
other than the Membership Units held by CII, and decreasing the Adjustment
Amount (which may be a negative number) by the amount of any outstanding
material liabilities (other than obligations pursuant to options, warrants or
other similar rights held by any person to purchase common stock of CII), all in
the manner reflected in Section 2.3(b) of the Exchange Agreement.

4. Closing.


                                      -3-

<PAGE>   4
        A. At the Closing, (a) CII or its designee shall pay to the Holder an
amount equal to the product of (i) the Purchase Price, and (ii) the number of
shares of Common Stock that are to be purchased and sold at the Closing, in
immediately available funds by wire transfer or certified bank check; and (b)
the Holder shall deliver to CII or its designee one or more certificates
evidencing the Common Stock to be purchased and sold at the Closing, together
with duly executed assignments separate from certificate in form and substance
sufficient to effectuate the transfer of such Common Stock to CII or its
designee, together with a certificate of the Holder and its Permitted
Transferee, if applicable, reaffirming the representations in Section 5.

        B. The closing (the "Closing") shall be held at the offices of Irell &
Manella LLP in Los Angeles, California, on a Business Day selected by CII (as to
which prompt written notice is to be given to the Holder) no later than 30
Business Days after the delivery of notice that the Put Option is being
exercised, or at such other time and place as the Holder and CII may agree. The
Holder and CII will cooperate so as to permit all documents required to be
delivered at the Closing to be delivered by mail, delivery service, courier, or
other agreed-upon method without requiring either party or his or its
representatives to be physically present at the Closing.

5. Adjustment for Exchange, Reorganizations, etc.

        A. Upon a reorganization, merger or consolidation of CII with one or
more other corporations or entities (any of the foregoing, a "Business
Combination") pursuant to which outstanding shares of Common Stock are converted
into or exchanged solely for any other security ("Replacement Securities"), the
Put Option shall cease to be exercisable with respect to the securities that
previously constituted "Common Stock" and shall instead be automatically
converted into an option to sell such number of shares or units of Replacement
Securities issued in exchange for the Common Stock pursuant to such Business
Combination at a price per share or unit of Replacement Securities equal to the
aggregate Purchase Price for all Common Stock immediately prior to such
effectiveness divided by the number of shares or units of Replacement Securities
subject to the Put Option immediately following such effectiveness unless such
Replacement Securities are securities of CCI or another entity and are publicly
traded on a national securities exchange or on NASDAQ, in which case this put
shall immediately terminate and be of no further force or effect. Any
Replacement Securities that become subject to the Put Option pursuant to this
Section 5.A shall constitute "Common Stock" for purposes of this Agreement.

        B. In the event of any proposed Business Combination pursuant to which
the outstanding Common Stock will be converted into a right to receive
consideration in whole or in part other than securities of CII or Replacement
Securities, (i) CII will provide notice thereof to the Holder at least twenty
(20) days prior to consummation of such Business Combination and (ii) the Put
Option will expire two days prior to such consummation except with respect to
any shares of Common Stock that are specified in a put notice delivered by the
Holder pursuant to Section 2 prior to such date. If the Holder delivers a notice
pursuant to Section 2 after its receipt of a notice from CII pursuant to this
Section 5.B, the purchase and sale of any of the Common Stock specified in the
Holder's notice may be conditioned at the Holder's option on the consummation of
the Business Combination described in CII's notice pursuant to this Section 5.B.
