                               FIRST AMENDMENT TO
                             CONTRIBUTION AGREEMENT

as of September 14, 1999, by and among Charter Communications Operating, LLC, a
Delaware limited liability company ("CCO"); Charter Communications Holding
Company, LLC, a Delaware limited liability company ("CHARTER HOLDCO"); the other
Persons listed on the signature pages thereto (the "INVESTORS"); with respect to
certain provision thereof, Charter Communications, Inc. ("CCI"); and with
respect to certain provisions thereof, Paul G. Allen ("ALLEN"), is entered into
as of November ___, 1999.

                                    RECITALS

      A. In connection with the transactions contemplated by the Purchase
Agreements, CCO, Charter Holdco, the Investors, CCI and Allen entered into that
certain Contribution Agreement dated as of September 14, 1999 (the "CONTRIBUTION
AGREEMENT").

      B. Section 6.6 of the Contribution Agreement provides that the
Contribution Agreement may be amended by an instrument in writing executed by a
majority-in-interest (measured by Issued Units) of the Investors, so long as
such amendment does not have an adverse and discriminatory impact on any
Investor.

      C. The parties executing this Amendment, representing a
majority-in-interest (measured by Issued Units) of the Investors, wish to amend
the Contribution Agreement in the manner set forth in this Amendment, all
effective as of September 14, 1999.

      D. Capitalized terms used in this Amendment but not otherwise defined have
the meaning ascribed to them in the Contribution Agreement.

                                    AGREEMENT

      In consideration of the premises contained herein and the agreements set
forth below, and intending to be legally bound, the parties agree that the
Contribution Agreement is hereby amended as follows:

1. Sections 3 of the Contribution Agreement is hereby amended and restated in
   its entirety as follows:

      "3. Right to Exchange Class A Preferred Units; Put Rights.

            3.1. Right to Exchange. Each Investor will have the right to
      contribute all or any portion of its Issued Units to CCI in exchange for
      Common Stock immediately prior to or concurrently with the IPO, in the
      following manner:

                  3.1.1. Prior hereto, CCI has delivered to R&A Management LLC
            copies of the preliminary prospectus dated October 18, 1999,
            relating to the IPO, and the Disbursement Agent has delivered a copy
            of the preliminary prospectus to each Investor.

                                      -1-

<PAGE>   2
                  3.1.2. On or before November 5, 1999, the Disbursement Agent
            shall deliver a notice to CCI stating the number of Issued Units, if
            any, that each Investor will commit to exchange into shares of
            Common Stock concurrently with the closing of the IPO (the
            "EXCHANGED UNITS"). If no such notice is delivered with respect to
            one or more Investors, then each such Investor will no longer have
            the right to exchange Issued Units into shares of Common Stock. Each
            Investor electing to exchange Issued Units for Common Stock will,
            upon delivery of the confirmation notice, execute and deliver a
            Contribution Agreement in the form attached hereto as EXHIBIT C (the
            "SECOND CONTRIBUTION AGREEMENT"). Such election and such deliveries
            shall be contingent upon closing of the IPO and the fulfillment of
            all of the obligations of Charter Holdco, CCI and their affiliates
            hereunder, including without limitation the delivery of the
            Accretion Put and Registration Support Put as provided herein.

            3.2. Valuation of Exchanged Units and CCI Common Stock. As more
      fully set forth in the Second Contribution Agreement, for purposes of the
      exchange under Section 3.1:

                  3.2.1 shares of Common Stock shall be valued at the gross
      price to the public in the IPO; and

                  3.2.2 Exchanged Units shall be valued at the sum of (i) the
      Class A Preferred Contributed Amount in respect of the Exchanged Units,
      and (ii) the Class A Preferred Return Amount in respect of such Exchanged
      Units (the aggregate value of all such Exchanged Units being referred to
      as the "ROLLOVER AMOUNT").

            3.3. Lockup Agreement. Investors receiving shares of Common Stock in
      exchange for Exchanged Units (the "ROLLOVER INVESTORS") will enter into a
      lockup agreement with the underwriters of the IPO, in the form attached
      hereto as EXHIBIT G.

            3.4. Loss of Exchange Rights. Issued Units that are not exchanged
      for shares of Common Stock concurrently with the IPO will remain as Class
      A Preferred Units and will no longer be exchangeable into shares of Common
      Stock.

            3.5. Registration Rights Agreement. Each Rollover Investor and CCI
      shall enter into a Registration Rights Agreement in the form attached
      hereto as EXHIBIT H.

            3.6. Put Rights. The Charter Put (as defined in Section 5) entered
      into at the Closing will not apply as to any shares of Common Stock
      received in exchange for Issued Units ("ROLLOVER SHARES"). Allen will
      deliver two put agreements in the forms attached hereto as EXHIBIT E (the
      "ACCRETION PUT") and EXHIBIT F (the "REGISTRATION SUPPORT PUT") to each
      Investor that elects to exchange Issued Units into Common Stock.

            3.7. Credit Support.

                  3.7.1 Delivery of LC or Collateral. At the closing under the
      Second Contribution Agreement, Allen shall either:

                  (i) deliver to the Disbursement Agent a letter of credit from
            a bank, investment bank or other financial institution reasonably
            acceptable to the Disbursement Agent in form and substance
            reasonably acceptable to the Disbursement Agent, in an amount at
            least equal to the Rollover Amount (the "LETTER OF CREDIT"); or

                  (ii) deliver into escrow, as collateral securing Allen's
            obligations under the Registration Support Put, marketable
            securities (which shall include, for this purpose, shares of
            Microsoft Corp. common stock which Allen has held for at least two
            years) having a then market value at least equal to the Rollover
            Amount (the "COLLATERAL") together with a pledge agreement in form
            and substance reasonably acceptable to the Disbursement Agent
            securing Allen's obligations under the Registration Support Put (the
            "PLEDGE AGREEMENT"); provided, however, that, except to the extent
            action is properly taken against the Collateral as a result of
            Allen's failure to perform his obligations under the Registration
            Support Put, Allen shall at all times retain all rights incident to
            the ownership of such securities including without limitation voting
            rights and rights to receive dividends; or

                  (iii) deliver any combination of a Letter of Credit and
            Collateral under clause (i) or (ii) of this Sections 3.7.1 which in
            the aggregate are valued at the Rollover Amount.

                  3.7.2 Conditions for Use. The Letter of Credit shall provide
      that the Letter of Credit may be drawn upon (or, if applicable, the Pledge
      Agreement shall provide that action may taken against the Collateral) by
      the Disbursement Agent (on behalf of any Rollover Investor) only in the
      event, and only to the extent, that Allen breaches his obligation to
      purchase Rollover Shares from such Rollover Investor pursuant to Section 2
      of the Registration Support Put. In such case, the Letter of Credit or
      Collateral may be utilized either (i) to pay the full Purchase Price due
      under the Registration Support Put, provided that concurrently therewith
      title to the Rollover Shares is transferred to Allen or his designee in
      accordance with the terms of the Registration Support Put or (ii) to
      compensate such Rollover Holder for damages suffered as a result of such
      breach, if, following such breach by Allen, the Rollover Holder sells the
      Rollover Shares tendered to Allen to an unaffiliated third party under
      arms length commercially reasonable terms, with a reasonable and customary
      discount to reflect the fact that the Rollover Shares are "restricted
      shares" under rules and regulations of the SEC (an "ALTERNATE PRIVATE
      SALE"), which damages shall be deemed to be the difference between the
      aggregate amount which was payable by Allen under Section 2 of the
      Registration Support Put and the aggregate sale price received pursuant to
      such Alternate Private Sale. All draws upon the Letter of Credit, and all
      actions with respect to the Collateral, shall be made by the Disbursement
      on behalf of the claiming Rollover Holder. Each Investor hereby

                                      -3-
<PAGE>   4
      irrevocably appoints the Disbursement as its representative for such
      purpose (and the Disbursement Agent hereby accepts such appointment) and
      agrees that any action taken by the Disbursement Agent with respect to the
      Letter of Credit or the Collateral which purports to be on behalf of such
      Investor shall be binding on such Investor. Any payments received by the
      Disbursement Agent on behalf of any Investor shall discharge Mr. Allen's
      obligations to such Investor to the extent of such payments.

                  3.7.3 Duration. Such Letter of Credit or Pledge Agreement
      shall be maintained by Allen through the date which is 2 years following
      the closing date of the IPO. In the case of a Letter of Credit, the
      initial term shall be for one year; provided, however, that the
      Disbursement Agent shall be entitled to draw upon the Letter of Credit at
      the end of such one year period unless, at least 15 days prior thereto,
      either (i) the Letter of Credit is either affirmatively renewed or renewed
      under its terms by inaction of the bank or (ii) Allen provides a
      replacement Letter of Credit and/or replacement Collateral under a Pledge
      Agreement (provided such new Letter of Credit and Collateral have an
      aggregate value equal to or exceeding the then remaining face amount of
      the existing Letter of Credit). If the Disbursement Agent draws upon the
      Letter of Credit due to its expiration as set forth above, the
      Disbursement Agent shall deposit such funds in an appropriate escrow
      account, pursuant to agreements in form and substance reasonably
      acceptable to the parties, from which payments will be made to Investors
      in the event of a breach of the Registration Support Put as contemplated
      by Section 3.7.2 and the Letter of Credit. Any remaining funds in such
      escrow account will be returned to Mr. Allen two years following the date
      of the IPO.

                  3.7.4 Substitution; Reduction.

                  (a) Allen shall have the ability at any time from time to time
      to substitute a Letter of Credit for some or all of the Collateral, or
      Collateral for any portion of a Letter of Credit, on a dollar for dollar
      basis, and the Disbursement Agent shall cooperate with Allen in effecting
      the release of Collateral or a reduction of the amount of the Letter of
      Credit concurrently with delivery of such substitute Letter of Credit or
      Collateral (as the case may be).

                  (b) From time to time at Allen's request (but not more than
      once every three months), the Disbursement Agent shall cooperate with
      Allen to reduce the Letter of Credit or the amount of Collateral to an
      aggregate value not less than the greater of (i) the Rollover Amount
      multiplied by a fraction the numerator of which is the number of any
      remaining Rollover Shares which have neither been transferred to Allen nor
      sold to a third party that is not a Permitted Transferee (whether pursuant
      to the Shelf Registration or otherwise) and the denominator of which is
      the initial number of Rollover Shares; and (ii) the fair market value of
      such remaining Rollover Shares on the date of such request (as determined
      by reference to the Closing Price under the Registration Support Put).

            3.8. Earlier Offering by Entity other than CCI. In the event that an
      affiliate of Charter Holdco and CII other than CCI conducts an initial
      public offering of common stock prior to the IPO, then:

                  3.8.1. CII and Charter Holdco shall cause such affiliate to
            enter into an agreement with the Investors giving them substantially
            the same rights set forth in Sections 3.1, 3.2, 3.3 and 3.4; and

                  3.8.2. Allen shall enter into an agreement with the Investors
            giving them substantially the same rights set forth in Sections 3.5,
            3.6 and 3.7 (with the Accretion Put and Registration Support Put
            being applicable to common stock of such affiliate received by
            Investors in the initial public offering of such affiliate).

2. Exhibit C (Form of Second Contribution Agreement) to the Contribution
   Agreement is replaced in its entirety by Exhibit C to this Amendment.

3. Exhibit E (Form of Allen Put) to the Contribution Agreement is replaced in
   its entirety by Exhibit E (Form of Accretion Put) to this Amendment.

4. Exhibit F (Lockup Put) to the Contribution Agreement is deleted in its
   entirety, and a new Exhibit F (Registration Support Put) is hereby added in
   the form of Exhibit F hereto.

5. Exhibit H (Registration Rights Agreement) to the Contribution Agreement is
   attached hereto as Exhibit H hereto.

6. On or prior to the closing under the Second Contribution Agreement, Section
   3.5.3 of the LLC Agreement shall be amended in its entirety to read as
   follows:

            "3.5.3 Right to Redeem Class A Preferred Units. At any time after
      the third anniversary of the Class A Preferred Measuring Date, the Company
      shall have the right to redeem the Class A Preferred Units at a redemption
      price equal to the sum of (i) the Class A Preferred Contributed Amount in
      respect of such redeemed Class A Preferred Units and (ii) the Class A
      Preferred Return Amount in respect of such redeemed Class A Preferred
      Units. The Class A Preferred Units redeemed pursuant to this Section 3.5.3
      shall be deemed cancelled."

7. Except as otherwise set forth in this Amendment, the Contribution Agreement
   remains unchanged and in full force and effect and the terms of Section 6 of
   the Contribution Agreement are incorporated herein and shall be applicable to
   this Amendment. Without limiting any of the foregoing, each Investor
   acknowledges that former Section 3 of the Contribution Agreement (and any
   similar provision of any letter agreement referenced in the Contribution
   Agreement) is of no further force and effect and that the execution and
   delivery of this agreement constitutes settlement in full of all claims or
   rights arising out of any failure by any party to comply with former Section
   3 and any such similar provision of any letter agreement.

                                      -5-

8. This Amendment may be executed in any number of counterparts, each of which
   will be deemed an original, but all of which together will constitute one and
   the same instrument.

necessary action on the part of CCI, (iii) this Agreement has been duly and

<PAGE>   14
agreement of CCI, enforceable against CCI in accordance with its terms, except
(a) as such enforcement may be subject to bankruptcy, insolvency or similar laws
now or hereafter in effect relating to creditors rights generally and (b) as the
remedy of specific performance and injunctive and other forms of equitable
relief may be subject to equitable defenses and to the discretion of the court
before which any proceeding therefor may be brought.

      3.2. Holder's Representations and Warranties. Holder hereby represents and
warrants to CCI as follows:

            3.2.1. Holder has the full power and authority to execute and
deliver this Agreement and to consummate the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by Holder and is
a valid and binding agreement of Holder, enforceable against it in accordance
with its terms, except as (a) such enforcement may be subject to bankruptcy,
insolvency or similar laws now or hereafter in effect relating to creditors
rights generally and (b) as the remedy of specific performance and injunctive
and other forms of equitable relief may be subject to equitable defenses and to

            3.2.2. Holder, either alone or (if such Holder designated a
Purchaser Representative in connection with its September 14 acquisition of the
Contributed Units from Holdco) together with a Purchaser Representative (which
Purchaser Representative has completed and delivered to CII a completed
"Purchaser Representative Questionnaire" delivered to each Holder in the Equity
Letter), is an "accredited investor" as defined in Securities and Exchange
Commission ("SEC") Rule 501(a). The "Investor Questionnaire" that was completed
by Holder and delivered to CII together with the executed letter agreement dated
August 27, 1999 from CII to each of the Holders is true and correct in all
material respects as of the date hereof. If, pursuant to such Investor
Questionnaire, Holder designated a "Purchaser Representative", (i) Holder hereby
confirms its appointment of such Purchaser Representative as its purchaser
representative in connection with its purchase of CCI Stock hereunder and (ii)
to the best of Holder's knowledge, such Purchaser Representative's Purchaser
Representative Questionnaire is true and correct in all material respects as of
the date hereof. If Holder acted in the capacity of "Purchaser Representative"
for any other purchaser of Class A Preferred Units, (i) Holder hereby confirms
its appointment as purchaser representative in connection with the purchase of
CCI stock hereunder and (ii) that its previously delivered Purchaser
Representative Questionnaire is true and correct in all material respects as of
the date hereof.

entity, Holder was not organized for the specific purpose of acquiring the
Common Stock.

            3.2.4. Holder has received and reviewed all information Holder
considers necessary or appropriate for deciding whether to invest in the Common
Stock. Holder further represents that Holder has had an opportunity to ask
questions and receive answers from CII, CCI, CCO and Charter Holdco and its
officers and employees regarding the terms and conditions of purchase of the
Common Stock and regarding the business, financial affairs and other aspects of
CCI and has further had the opportunity to obtain any information (to the extent
CII, CCI, CCO or Charter Holdco possesses or can acquire such information
without unreasonable effort or expense) that Holder deems necessary to

                                      -3-
<PAGE>   15
evaluate the investment and to verify the accuracy of information otherwise
provided to Holder.

            3.2.5. Holder acknowledges that the Common Stock has not been
registered under the Act, or qualified under any applicable blue sky laws in
reliance, in part, on the representations and warranties herein. Such Issued
Units are being acquired by Holder for investment purposes for Holder's own
account only and not for sale or with a view to distribution of all or any part
of such Common Stock. No other person will have any direct or indirect
beneficial interest in the Common Stock.

            3.2.6. Holder understands that the shares of Common Stock are and
will be "restricted securities" under the federal securities laws in that such
securities will be acquired from CCI in a transaction not involving a public
offering, and that under such laws and applicable regulations such securities
may be resold without registration under the Act only in certain limited
circumstances and that otherwise such securities must be held indefinitely.

            3.2.7. Holder understands and acknowledges that the shares shall
bear a legend stating in substance:

            THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
            SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY
            STATE, AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED,
            PLEDGED OR HYPOTHECATED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
            STATEMENT UNDER SAID ACT (AND ANY APPLICABLE STATE SECURITIES LAWS)
            OR AN APPLICABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS
            THEREOF.

      3.3. At the Closing, Holder will own all of the Contributed Units, 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 Contributed Units), other than
those arising under applicable law and those arising under the Operating
Agreement.

      3.4. Upon the transfer of the Contributed Units, CCI will receive good
title to the Contributed Units, free and clear of all liens, encumbrances and
adverse interests created by the Holder or any of the Holders
predecessors-in-interest, other than those arising under applicable law or those
arising under the Operating Agreement.

4.    CLOSING; CLOSING CONDITIONS.

"CLOSING") shall occur simultaneously with (and shall be contingent upon) the
closing of the IPO and shall take place at a location specified by CCI. At the
Closing, Holder shall (a) contribute to CCI the Contributed Units, (b) deliver
or cause to be delivered to CCI one or more certificates evidencing the
Contributed Units (if such interests are certificated), together with duly

separate from the certificate in form and substance reasonably acceptable to
Allen to effectuate the transfer of such CCI Stock to Allen or his designee,

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

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

                                      -3-
<PAGE>   25
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 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

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.

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

         NOW, THEREFORE, in consideration of the respective covenants and
agreements of the parties and for other good and valuable consideration (the

Exhibit A hereto delivered to Allen at any time after the date that is 180 days
from the date hereof until the date of termination of the Put Option under
Section 7, to sell and to permit any of the Holder's Permitted Transferees to

or any portion of the Registrable Securities (as defined in the Registration
Statement) held by the Holder and its Permitted Transferees; provided, however,
that the Put Option shall not be exercisable unless on the date the written
notice of exercise is delivered the Registrable Securities specified in the

Section 2 (or if such date is not a trading day, then the Closing Price on the
next trading day).

            3.2 At each closing of the purchase and sale of the CCI Stock
pursuant to the exercise of the Put Option (the "Closing"), (a) Allen or his
designee shall pay to the Holder (for itself and on behalf of its Permitted

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

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.

changed into, or exchanged for a different number or kind of publicly-traded
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
Combination") pursuant to which the outstanding CCI Stock is converted into or
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

day is not a Business Day, then such action or notice shall be deferred until,
or may be taken or given on, the next Business Day.

         2. Shelf Registration.

            2.1 Shelf Registration. Charter shall file, and use its best efforts
to cause to become effective by the date which is six months after the date
hereof, a Registration Statement registering the sale by the Stockholders of all
of the Registrable Securities; provided, however, that during the time the

Section 2.3.

            2.2 Other Securities. In addition to the Registrable Securities, the
Registration Statement may also register the sale of securities to be sold for
the account of Charter or for any stockholder of Charter not holding Registrable
Securities.

            2.3 Delay of Filing or Sales.

               (a) Charter shall have the right, exercisable by giving written
notice of the exercise of such right to the applicable Selling Stockholders,
subject to Section 2.3(b), at any time and from time to time, to delay filing or
the declaration of effectiveness of a Registration Statement or to require the
applicable Selling Stockholders not to sell any Registrable Securities pursuant
to an effective Registration Statement for a period not in excess of 120 days
beginning on the date on which such notice is given, or such shorter period of
time as may be specified in such notice or in a subsequent notice delivered by
Charter to such effect prior to or during the effectiveness of the Registration
Statement, if:


                                      -4-
<PAGE>   48
                  (i) Charter is engaged in discussions or negotiations with
respect to, or there otherwise is pending, any merger, acquisition, or other
form of business combination that is "probable" (within the meaning of the
Securities Act), any divestiture, tender offer, financing, or other event that,
in any such case, is material to Charter (any such activity or event, a
"Material Event"),

                  (ii) such Material Event would, in the judgment of Charter's
board of directors (after consultation with counsel), require disclosure so as
to permit the Registrable Securities to be sold in compliance with law, and

                  (iii) disclosure of such Material Event would, in the judgment
of Charter's board of directors (after consultation with counsel), be adverse to
its interests.

            (b) Charter may not delay the filing of a Registration Statement or
the sale of any Registrable Securities, whether pursuant to one or more notices
pursuant to Section 2.3(a), for more than an aggregate of 120 days within any
12-month period.

            (c) Charter shall have the right, exercisable by giving notice of
the exercise of such right to the applicable Selling Stockholders, to delay
filing or the declaration of effectiveness of a Registration Statement during
any period in which, as a result of Charter's failure to satisfy the conditions
in Rule 3-01(c) of Regulation S-X, Charter is required to include in the
Registration Statement audited financial statements of Charter prior to the date
on which such audited financial statements would normally have been prepared in
accordance with Charter's past practices and the SEC's periodic reporting
requirements.

            2.4 Continuing Effectiveness of Registration Statement. In
connection with any registration pursuant to Section 2.1, subject to Section
2.3, Charter will use its best efforts to prepare and file with the SEC any
amendments and supplements to the Registration Statement and the Prospectus used
in connection therewith, and to take any other actions, that may be necessary to
keep the Registration Statement and the Prospectus effective, current, and in
compliance with the provisions of the Securities Act, until the date two years
from the date hereof (or, if earlier, the date on which there remain no
Registrable Securities outstanding).

         3. Obligations with Respect to Registration.

            3.1 Obligations of Charter. Whenever Charter is obligated by the
provisions of this Agreement to effect the registration of any Registrable
Securities under the Securities Act, Charter shall:

            (a) Within a reasonable time not to exceed ten Business Days prior
to filing a Registration Statement or Prospectus or any amendment or supplement
thereto (other than any amendment or supplement in the form of a filing that
Charter makes pursuant to the Exchange Act), furnish to each Selling Stockholder
copies of such Registration Statement or Prospectus as proposed to be filed,
which documents will be subject to the reasonable review and comments of the
Selling Stockholders (and their respective counsel) during such period, and
Charter will not file any Registration Statement or any Prospectus or any
amendment or supplement thereto containing any statements with respect to any
Selling Stockholder or the distribution of the Registrable Securities to be
included in such Registration Statement for sale


                                      -5-
<PAGE>   49
by such Selling Stockholder if such Selling Stockholder reasonably objects in
writing. Thereafter, Charter will furnish to each Selling Stockholder such
number of copies of such Registration Statement, each amendment and supplement
thereto (in each case including all exhibits thereto and any documents
incorporated by reference), the Prospectus included in such Registration
Statement (including each preliminary Prospectus), and such other documents as
such Selling Stockholder may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such Selling Stockholder.

            (b) After the filing of the Registration Statement, promptly notify
each Selling Stockholder of the effectiveness thereof and of any stop order
issued or threatened by the SEC and take all reasonable actions required to
prevent the entry of such stop order or to remove it at the earliest possible
moment if entered and promptly notify each Selling Stockholder of the lifting or
withdrawal of any such order.

            (c) Immediately notify each Selling Stockholder holding Registrable
Securities covered by the applicable Registration Statement at any time when a
Prospectus relating thereto is required to be delivered under the Securities
Act, of (i) the determination that a Material Event exists or (ii) the
occurrence of an event requiring the preparation of a supplement or amendment to
such Prospectus so that, as thereafter delivered to the purchasers of such
Registrable Securities, such Prospectus will not contain an untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading and promptly make available to such Selling
Stockholder any such supplement or amendment, and subject to the provisions of
this Agreement regarding the existence of a Material Event, Charter will
promptly prepare and furnish to each such Selling Stockholder a supplement to or
an amendment of such Prospectus so that, as thereafter delivered to the
purchasers of such Registrable Securities, such Prospectus will not contain any
untrue statement of material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading.

            (d) Make available for inspection by any Selling Stockholder covered
by such Registration Statement and any attorney, accountant, or other
professional retained by any such Selling Stockholder, all financial and other
records, pertinent corporate documents, and properties of Charter as shall be
reasonably necessary to enable them to exercise their due diligence
responsibility in connection therewith, and cause Charter's officers, directors,
and employees to supply all information reasonably requested by any of such
Persons in connection with such Registration Statement. Information that Charter
determines, in good faith, to be confidential and notifies such Persons is
confidential shall not be disclosed by such Persons unless (i) the release of
such information is ordered pursuant to a subpoena or other order from a court,
or other governmental agency or tribunal, of competent jurisdiction or (ii) such
information becomes public other than through a breach by such Persons of the
confidentiality obligations of such Persons. Each Selling Stockholder agrees
that information obtained by it as a result of such inspections shall be deemed
confidential and shall not be used by it as the basis for any transactions in
the securities of Charter or for any other purpose unless and until such
information is made generally available to the public.

            (e) Register or qualify the Registrable Securities covered by a
Registration Statement under the securities or blue sky laws of such United
States jurisdictions as the Stockholder Representative shall reasonably request,
and do any and all other acts and things which may be necessary to enable each
Selling Stockholder to consummate the disposition in such jurisdictions of such
Registrable Securities in accordance with the method of distribution described
in such Registration Statement; provided, however, that Charter shall not be
required (i) to qualify to do business as a foreign corporation in any
jurisdiction where it is not otherwise required to be so qualified, (ii) to
conform its capitalization or the composition of its assets at the time to the
securities or blue sky laws of such jurisdiction, (iii) to execute or file any
general consent to service of process under the laws of any jurisdiction, or
(iv) to subject itself to taxation in any jurisdiction where it has not
theretofore done so.

            (f) Use its best efforts to (i) cause such Registrable Securities
covered by a Registration Statement to be listed on the principal exchange or
exchanges or qualified for trading on the principal over-the-counter market or
listed on the automated quotation market on which securities of the same class
and series as the Registrable Securities (or into which such Registrable
Securities will be or have been converted) are then listed, traded, or quoted
upon the sale of such Registrable Securities pursuant to such Registration
Statement and (ii) provide a transfer agent and registrar for such Registrable
Securities covered by such Registration Statement not later than the effective
date of such Registration Statement.

            (g) Make and keep information publicly available relating to Charter
so as to satisfy the requirements of Rule 144 under the Securities Act (or any
successor or corresponding rule) and file with the SEC all reports and other
documents required of Charter under the Securities Act and the Exchange Act in a
timely manner.

            (h) Make available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least twelve
months, but not more than eighteen months, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act (provided that
Charter shall not be deemed in violation of this paragraph so long as it files
customary quarterly reports with the SEC for such period), and not file any
amendment or supplement to such Registration Statement or Prospectus to which
any of the Selling Stockholders shall have reasonably objected on the grounds
that such amendment or supplement does not comply in all material respects with
the requirements of the Securities Act.

            (i) Use its best efforts to cause such Registrable Securities
covered by such Registration Statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
seller or sellers thereof to consummate the disposition of such Registrable
Securities.

            (j) Cooperate with the Selling Stockholders to facilitate the timely
preparation and delivery of certificates (not bearing any restrictive legends)
representing securities to be sold under the Registration Statement, and enable
such securities to be in such denominations and registered in such names as such
Selling Stockholder may request.


                                      -7-
<PAGE>   51
            (k) Cooperate with each Selling Stockholder in the disposition of
such Registrable Securities and their respective counsel in connection with any
filings required to be made with the NASD.

         3.2 Selling Stockholders' Obligations. Charter's obligations under this
Agreement to a Selling Stockholder shall be conditioned upon such Selling
Stockholder's compliance with the following:

            (a) Such Selling Stockholder shall cooperate with Charter in
connection with the preparation of the Registration Statement, and for so long
as Charter is obligated to keep the Registration Statement effective, such
Selling Stockholder will provide to Charter, in writing, for use in the
Registration Statement, all information regarding such Selling Stockholder, its
intended method of disposition of the applicable Registrable Securities, and
such other information as Charter may reasonably request to prepare the
Registration Statement and Prospectus covering the Registrable Securities and to
maintain the currency and effectiveness thereof.

            (b) Such Selling Stockholder agrees that, upon receipt of any notice
from Charter of the happening of any event of the kind described in Section
3.1(c), such Selling Stockholder will discontinue its offering and sale of
Registrable Securities pursuant to the applicable Registration Statement until
such Selling Stockholder's receipt of either (i) notice from Charter that a
Material Event no longer exists (but for no longer than the end of the 120-day
period described in Section 2.3) or (ii) the copies of the supplemented or
amended Prospectus contemplated by Section 3.1(c), and, in either case, if so
directed by Charter, such Stockholder will deliver to Charter all copies in its
possession of the most recent Prospectus covering such Registrable Securities at
the time of receipt of such notice. In the event Charter shall give any such
notice, the period mentioned in clause (ii) of Section 2.4 shall be extended by
the number of days during the period from and including the date of the giving
of such notice pursuant to Section 3.1(c) and including the date when each
seller of Registrable Securities covered by such Registration Statement shall
have received the copies of the supplemented or amended prospectus contemplated
by Section 3.1(c).

            (c) Such Selling Stockholder agrees that, with respect to the
Registrable Securities, such Stockholder will not take any action (or agree to
take any action) that would reasonably be expected to toll or otherwise lengthen
the holding period under Rule 144(d) and Rule 144(k) under the Securities Act
(or any successor rule or provision).

         4. Expenses of Registration.

            4.1 Registration Expenses. Except as provided in Section 4.2 and
Section 4.3, all Registration Expenses incurred in connection with the
registration under Section 2.1 and and the distribution of any Registrable
Securities in connection therewith shall be borne by Charter. For purposes of
this Agreement, the term "Registration Expenses" means all:

                (a) registration, application, filing, listing, transfer, and
registrar fees,

                (b) NASD fees and fees and expenses of registration or
qualification of Registrable Securities under state securities or blue sky laws


                                      -8-
<PAGE>   52
                (c) printing expenses (or comparable duplication expenses),
delivery charges, and escrow fees,

                (d) fees and disbursements of counsel for Charter,

                (e) fees and expenses for independent certified public
accountants retained by Charter (including the expenses of any comfort letters
or costs associated with the delivery by independent certified public
accountants of a comfort letter or comfort letters),

                (f) fees and expenses of any special experts retained by Charter
in connection with such registration;

                (g) reasonable fees and disbursements of underwriters and
broker-dealers customarily paid by issuers or sellers of securities, and

                (h) fees and expenses of listing the Registrable Securities on a
securities exchange or over-the-counter market; and

                (i) all fees and disbursements of one counsel for all such
Selling Stockholders as a group attributable to the registration and sale of the
Registrable Securities of such Selling Stockholders included in such
registration.

            4.2 Selling Stockholder Expenses. Each Selling Stockholder shall pay
all stock transfer fees or expenses (including the cost of all transfer tax
stamps), if any, all underwriting or brokerage discounts and commissions and all
fees and disbursements of counsel for such Selling Stockholder (other than the
one counsel described in Section 4.1(i)) attributable to the distribution of the
Registrable Securities of such Selling Stockholder included in such
registration.


            4.3 Internal Expenses of Charter. Notwithstanding any other
provision of this Agreement, Charter shall be obligated to bear all internal
expenses of Charter in connection with the registration under Section 2.1
(including all salaries and expenses of its officers and employees performing
accounting and legal functions and related expenses).

         5. Indemnification.

            5.1 By Charter. Charter agrees to indemnify and hold harmless each
Stockholder Indemnified Party from and against any Losses, joint or several, to
which such Stockholder Indemnified Party may become subject under the Securities
Act, the Exchange Act, state securities or blue sky laws, common law or
otherwise, insofar as such Losses (or actions in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of a material
fact contained in the applicable Registration Statement or Prospectus, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, and Charter will
reimburse each such Stockholder Indemnified Party for any reasonable fees and
expenses of outside legal counsel for such Stockholder Indemnified Parties, or
other expenses reasonably incurred by them, as incurred, in connection with
investigating or defending any such claims; provided, however, that Charter will
not indemnify


                                      -9-
<PAGE>   53
or hold harmless any Stockholder Indemnified Party from or against any such
Losses (including any related expenses) to the extent such Losses (including any
related expenses) result from an untrue statement, omission or allegation
thereof which were (a) made in reliance upon and in conformity with written
information provided by or on behalf of the applicable Selling Stockholder
specifically and expressly for use or inclusion in the applicable Registration
Statement or Prospectus or (b) made in any Prospectus used after such time as
Charter advised such Selling Stockholder that the filing of a post-effective
amendment or supplement thereto was required, except that this proviso shall not
apply if the untrue statement, omission, or allegation thereof is contained in
the Prospectus as so amended or supplemented. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Stockholder Indemnified Parties and shall survive the transfer of such
securities by the Selling Stockholders.

            5.2 By Selling Stockholders. Each Selling Stockholder, individually
and not jointly, agrees to indemnify and hold harmless each Charter Indemnified
Party and each other Stockholder Indemnified Party from and against any Losses,
joint or several, to which such Charter Indemnified Party or any other
Stockholder Indemnified Party may become subject, insofar as such Losses (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the applicable
Registration Statement or the Prospectus, or any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading, if the statement or omission was made in reliance upon and
in conformity with written information provided by or on behalf of such Selling
Stockholder or any Person who controls such Selling Stockholder specifically and
expressly for use or inclusion in the applicable Registration Statement or
Prospectus; provided, however, that such Selling Stockholder will not indemnify
or hold harmless any Charter Indemnified Party or other Stockholder Indemnified
Party from or against any such Losses (including any related expenses) (a) to
the extent the untrue statement, omission, or allegation thereof upon which such
Losses (including any related expenses) are based was made in any Prospectus
used after such time as such Selling Stockholder advised Charter that the filing
of a post-effective amendment or supplement thereto was required, except the
Prospectus as so amended or supplemented, or (b) in an amount that exceeds the
net proceeds received by such Selling Stockholder from the sale of Registrable
Securities pursuant to such Registration Statement. Such indemnity shall remain
in full force and effect regardless of any investigation by or on behalf of
Charter Indemnified Parties or the Stockholder Indemnified Parties, and shall
survive the transfer of such securities by the Selling Stockholder.

            5.3 Procedures. Each Indemnified Party shall give notice to each
Indemnifying Party promptly after such Indemnified Party has actual knowledge of
any claim as to which indemnity may be sought, and the Indemnifying Party may
participate at its own expense in the defense, or if it so elects, assume the
defense of any such claim and any action or proceeding resulting therefrom,
including the employment of counsel and the payment of all expenses; provided
that such counsel shall be reasonably satisfactory to the Indemnified Party. The
failure of any Indemnified Party to give notice as provided in this Section 5.3
shall not relieve the Indemnifying Party from its obligations to indemnify such
Indemnified Party, except to the extent the Indemnified Party's failure to so
notify actually prejudices the Indemnifying Party's ability to defend against
such claim, action, or proceeding. If the Indemnifying Party


                                      -10-
<PAGE>   54
elects to assume the defense in any action or proceeding, an Indemnified Party
shall have the right to employ separate counsel in such action or proceeding and
to participate in the defense thereof, but such Indemnified Party shall pay the
fees and expenses of such separate counsel unless (a) the Indemnifying Party has
agreed to pay such fees and expenses, or (b) the named parties to any such
action or proceeding (including any impleaded parties) include such Indemnified
Party and the Indemnifying Party, and such Indemnified Party shall have been
advised by counsel that there is or would be a conflict of interest between such
Indemnified Party and the Indemnifying Party in the conduct of the defense of
such action (in which case, if such Indemnified Party notifies the Indemnifying
Party in writing that it elects to employ separate counsel at the expense of the
Indemnifying Party, the Indemnifying Party shall not assume the defense of such
action or proceeding on such Indemnified Party's behalf) or (c) the Indemnifying
Party shall not have employed counsel reasonably satisfactory to the Indemnified
Party to represent the Indemnified Party within a reasonable time after notice
of the institution of such claim. No Indemnifying Party, in the defense of any
such claim or litigation, shall, except with the consent of the Indemnified
Party (which consent will not be unreasonably withheld), consent to entry of any
judgment, or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation.

            5.4 Contribution. If the indemnification provided for under this
Section 5 is unavailable to or insufficient to hold the Indemnified Party
harmless under Section 5.1 or Section 5.2 above in respect of any Losses
referred to therein for any reason other than as specified therein, then the
Indemnifying Party shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party, on the one
hand, and such Indemnified Party, on the other, in connection with the
statements or omissions that resulted in such Losses. The relative fault of each
Indemnifying Party or Indemnified Party, as the case may be, shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by (or that was failed to be
supplied by) such Indemnifying Party or Indemnified Party, such party's relative
intent, knowledge, access to information, and opportunity to correct or prevent
such statement or omission. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

            5.5 Other Indemnification. Indemnification similar to that specified
in the preceding provisions of Section 5 (with any necessary changes thereto
having been made in order to effectuate the general intent thereof) shall be
given by Charter and each seller of Registrable Securities to the applicable
Indemnified Parties with respect to any required registration or other
qualification of securities under any federal or state law or regulation or
governmental authority other than the Securities Act.

         6. Miscellaneous.

            6.1 Notices.


                                      -11-
<PAGE>   55
              (a) All notices, requests, demands, waivers, and other
communications under this Agreement shall be in writing and shall be deemed to
have been duly given if delivered personally, mailed, certified or registered
mail with postage prepaid, or sent by reliable overnight courier, or facsimile
transmission, to the address or facsimile number specified for the applicable
party on Schedule A attached to this Agreement, or to such other Person,
address, or facsimile number as any party shall specify by notice in writing to
the other parties.

              (b) Any notice or other communication to a party in accordance
with the provisions of this Agreement shall be deemed to have been given (i)
three Business Days after it is sent by certified or registered mail, postage
prepaid, return receipt requested, (ii) upon receipt when delivered by hand or
transmitted by facsimile (confirmation received), or (iii) one Business Day
after it is sent by a reliable overnight courier service, with acknowledgment of
receipt requested. Notwithstanding the preceding sentence, notice of change of
address shall be effective only upon actual receipt thereof.

            6.2 Amendment. This Agreement may not be modified or amended except
by an instrument in writing signed by Charter and a majority-in-interest
(measured by Registrable Securities) of the Stockholders (except to the extent
such amendment would have an adverse and discriminatory impact on any
Stockholder, in which event such Amendment shall only be binding on such
Stockholder if such Stockholder has executed such amendment). No consent,
waiver, or similar act shall be effective unless in writing.

            6.3 Entire Agreement. This Agreement constitutes the entire
agreement among the parties hereto and supersedes all prior agreements and
understandings, oral and written, among the parties hereto with respect to the
subject matter hereof.

            6.4 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

            6.5 Governing Law. This Agreement shall be governed by and
interpreted in accordance with the internal laws of the State of New York,
without giving effect to principles of conflicts of laws.

            6.6 Remedies. In the event of CCI's breach or other failure to
perform under this Agreement, each Holder agrees that the sole and exclusive
remedy for such breach shall be under such Holder's Registration Support Put;
provided, however, that if Paul G. Allen breaches a Holder's Registration
Support by failing to purchase securities that he would otherwise be obligated
to purchase under the terms thereof, and such holder's damages are not satisfied
pursuant to the Letter of Credit and/or Collateral provided under the
Contribution Agreement, then this Section 6.6 shall not limit such Holder's
remedies against CCI in the event CCI breaches the terms of this Agreement.

            6.7 Assignment.

              (a) Except as expressly provided in this Section 6.7, the rights
of the parties hereto cannot be transferred or assigned and any purported
assignment or transfer to the contrary shall be void ab initio. Any Stockholder
may transfer any of its rights under this


                                      -12-
<PAGE>   56
Agreement, without the consent of Charter, to any Person to whom such holder
transfers any Registrable Securities or any rights to acquire Registrable
Securities, whether such transfer is by sale, gift, assignment, pledge, or
otherwise, so long as the terms of this Section 6.7 are followed, and so long as
(x) such transfer is not made pursuant to an effective Registration Statement or
pursuant to Rule 144 or Rule 145 (or any successor provisions) under the
Securities Act or in any other manner the effect of which is to cause the
transferred securities to be freely transferable without regard to the volume
and manner of sale limitations set forth in Rule 144 (or any successor
provision) in the hands of the transferee as of the date of such transfer; and
(y) such transfer is made to a Permitted Transferee.

              (b) Notwithstanding Section 6.7(a), no Stockholder may assign any
of its rights under this Agreement to any Person to whom such Stockholder
transfers any Registrable Securities unless the transfer of such Registrable
Securities did not require registration under the Securities Act.

              (c) The nature and extent of any rights assigned shall be as
agreed to between the assigning party and the assignee. No Person may be
assigned any rights under this Agreement unless Charter is given written notice
by the assigning party at the time of such assignment stating the name and
address of the assignee, identifying the securities of Charter as to which the
rights in question are being assigned, and providing a detailed description of
the nature and extent of the rights that are being assigned. Any assignee
hereunder shall receive such assigned rights subject to all the terms and
conditions of this Agreement, including the provisions of this Section 6.7.
Subject to the foregoing, this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns.

         6.8 Binding Agreement; No Third Party Beneficiaries. This Agreement
will be binding upon and inure to the benefit of the parties hereto and their
successors and permitted assigns. Except as set forth herein and by operation of
law, no party to this Agreement may assign or delegate all or any portion of its
rights, obligations, or liabilities under this Agreement without the prior
written consent of each other party to this Agreement.
