Operating, none of the representations and warranties made by Magellan in the

any other commission or financial advisory fee based on any agreement or
undertaking made by Crescent Operating in connection with the transactions
contemplated by this Agreement.

         3.8 Restrictions on Transfer. Crescent Operating understands that the
Charter LLC Interest has not been registered under the Securities Act or the
securities laws of any state (collectively, "Securities Acts") and may not be
resold unless permitted under applicable exemptions contained in such Securities
Acts or upon satisfaction of the registration or qualification requirements of
such Securities Acts. Crescent Operating acknowledges that it must bear the
economic risk of its investment in the Charter LLC Interest for an indefinite
period of time since the Charter LLC Interest has not been registered or
qualified under such Securities Acts and, therefore, cannot be sold unless it is
subsequently registered or exemptions from registration or qualification are
available.

         3.9      Qualification of Crescent Operating.

                  (a) Crescent Operating is acquiring the Charter LLC Interest
for investment purposes only, for its own account, not as nominee or agent for
any other person, firm or corporation, and not with a view to, or for resale in
connection with, a distribution or public offering thereof within the meaning of
such Securities Acts.

                  (b) Crescent Operating has knowledge and experience in
financial and business matters, is capable of evaluating the merits and risks of
its investment in the Charter LLC Interest, and is able to bear the economic
risks inherent in its investment in the Charter LLC Interest.

         3.10 Commission Filings. Crescent Operating has filed all required
documents with the Commission since June 12, 1997 (the "Filings"). As of their
respective dates, the Filings complied in all material respects with the
requirements of the Securities Act or the Exchange Act, as the case may be, and,
at the respective times they were filed, none of the Filings contained any
untrue statement of a material fact or omitted to state 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.

                                   ARTICLE VI

              INDEMNIFICATION AND ASSUMPTION OF CERTAIN LIABILITIES

         6.1 Indemnification for Breach of Representation or Warranty.

                  (a) After the Closing, Charter Inc. agrees to indemnify and
hold Crescent Operating harmless from any claims, liabilities, obligations,
losses, costs, expenses, penalties, fines, judgments and other damages,
including reasonably attorneys' fees and expenses (collectively "Damages"),
incurred by Crescent Operating as a result of (i) any breach by Charter Inc. of
any representation or warranty of Charter Inc. contained in Article II of this
Agreement; or (ii) a failure by Charter Inc. to perform in any material respect
any covenant or agreement required to be performed by it under this Agreement;
provided, however, that Charter Inc. shall have no liability to Crescent
Operating under this paragraph unless Crescent Operating shall have first
delivered to Charter Inc. a written claim to indemnification hereunder on or
before the date which is 18 months after the Closing Date, except as otherwise
provided in Section 8.1; provided, further, that Charter Inc. shall not be
liable for Damages in excess of an aggregate of $100,000,000 under this
Agreement, the Purchase Agreement[and the Joint Venture Purchase Agreement to be
entered into by Magellan and CBHS prior to the closing of the transactions
contemplated by the Purchase Agreement (the "Indemnification Cap").

                  (b) After the Closing, Crescent Operating agrees to indemnify
and hold Charter Inc. harmless from any Damages incurred by Charter Inc. as a
result of (i) any breach by Crescent Operating of any representation or warranty
of Crescent Operating contained in Article III of this Agreement; or (ii) a
failure by Crescent Operating to perform in any material respect a covenant or
agreement required to be performed by it under this Agreement; provided,
however, that Crescent Operating shall have no liability to Charter Inc. under
this paragraph unless Charter Inc. shall have first delivered to Crescent
Operating a written claim to indemnification hereunder on or before the date
which is 18 months after the Closing Date; provided, further, that Crescent
Operating shall not be liable for Damages in excess of the Indemnification Cap.

                                      -13-





                  (c) Subject to the provisions of Sections 6.1(a) and 6.1(b),
in the event of the occurrence of an event in which any party asserts a claim
for Damages, such party shall provide the indemnifying party with prompt notice
of such event and shall otherwise make available to the indemnifying party all
relevant information which is material to the claim and which is in the
possession of the indemnified party. If such event involves the claim of any
third party (a "Third-Party Claim"), the indemnified party shall have the right
to elect to join in the defense, settlement, adjustment or compromise of any
such Third-Party Claim, and to employ counsel to assist such indemnifying party
in connection with the handling of such claim, at the sole expense of the
indemnifying party, and no such claim shall be settled, adjusted or compromised,
or the defense thereof terminated, without the prior consent of the indemnifying
party unless and until the indemnifying party shall have failed, after the lapse
of a reasonable period of time, but in no event more than 30 days after written
notice to it of the

Third-Party Claim, to join in the defense, settlement, adjustment or compromise
of the same. An indemnified party's failure to give timely notice or to furnish
the indemnifying party with any relevant data and documents in connection with
any Third-Party Claim shall not constitute a defense (in part or in whole) to
any claim for indemnification by such party, except and only to the extent that
such failure shall result in any material prejudice to the indemnifying party.
If so desired by any indemnifying party, such party may elect, at such party's
sole expense, to assume control of the defense, settlement, adjustment or
compromise of any Third-Party Claim, with counsel reasonably acceptable to the
indemnified parties, insofar as such claim relates to the liability of the
indemnifying party, provided that such indemnifying party shall obtain the
consent of all indemnified parties before entering into any settlement,
adjustment or compromise of such claims, or ceasing to defend against such
claims, if as a result thereof, or pursuant thereto, there would be imposed on
an indemnified party any material liability or obligation not covered by the
indemnity obligations of the indemnifying parties under this Agreement
(including, without limitation, any injunctive relief or other remedy). In
connection with any Third-Party Claim, the indemnified party, or the
indemnifying party if it has assumed the defense of such claim pursuant to the
preceding sentence, shall diligently pursue the defense of such Third-Party
Claim.

                  (d) The amount of any and all Damages for which
indemnification is provided pursuant to this Article VI shall be net of any
amounts received by the indemnified party under insurance policies with respect
to such Damages (it being understood that any proceeds obtainable from a captive
insurance company of the indemnified party or any amounts which the indemnified
party self-insures shall not be so taken into account). In the event that any
claim for indemnification asserted under this Article VI is, or may be, the
subject of the insurance coverages of Charter Inc. and Crescent Operating, the
indemnified party agrees to promptly notify the applicable insurance carrier of
such claim and tender defense thereof to such carrier. If insurance coverage is
denied (in whole or in part), or if no resolution of an insurance claim shall
have occurred upon payment of the relevant indemnification obligation, the
indemnifying party shall be subrogated to the rights of the indemnified party
against such insurance carrier.

         (e) The indemnification provided in this Article VI and the obligations
in Section 7.2 shall be the exclusive remedy of the parties for any breach of
this Agreement.

                                      -14-





                                   ARTICLE VII

                          TERMINATION PRIOR TO CLOSING

         7.1 Termination Prior to Closing. This Agreement may be terminated and
abandoned at any time prior to the Closing:

                  (a) by the mutual consent of Charter Inc. and Crescent 
Operating; or

                  (b) by Charter Inc. or Crescent Operating, in the event the
Closing has not occurred by the date which is six months after the date of this
Agreement (the "Cut-Off Date"), unless failure of such consummation shall be due
to the failure of the party seeking to terminate this Agreement to comply in all
material respects with the agreements and covenants contained herein to be
performed by such party on or before the Cut-Off Date.

         7.2 Effect of Termination. In the event of the termination of this
Agreement pursuant to Section 7.1 hereof, such termination shall be without
liability or obligation of either party (or any director, officer, employee, or
representative of such party) to the other party to this Agreement; provided
that if such termination shall result from the willful failure of either party
to fulfill a condition to the performance of the obligations of the other party
or to perform a covenant of this Agreement or from a breach by either party to
this Agreement, such party shall be fully liable for any and all Damages
incurred or suffered by the other party as a result of such failure or breach.
The provisions of Section 8.5 shall survive any termination hereof pursuant to
Section 7.1.

                                  ARTICLE VIII

this Agreement shall expire, and be terminated and extinguished, on the date
which is 18 months after the Closing Date, and thereafter neither Charter Inc.
nor Crescent Operating, nor any officer, director or principal thereof, shall
have any liability whatsoever with respect to any such representation or
warranty, except that the representations and warranties in Sections 2.1(a), (c)
and (d), 2.2, 3.1(a) and (c) and 3.2 shall survive without limitation, and that
the representations and warranties in Sections 2.5 and 2.6 shall survive until
the applicable statute of limitations period for any applicable claim. The
covenants and agreements of the parties contained herein shall survive the
Closing to the extent they relate to an agreement or obligation to be performed
after the Closing.

or modified shall not be rendered unenforceable or impaired but shall remain in

Controversy, in order to attempt to resolve such Controversy. In this regard,
each party agrees to involve its respective senior management in these
discussions if necessary.

                  (b) In the event that such Controversy is not resolved through
mutual discussions within such 45-day period of time, such dispute or
controversy may be submitted by any such party to, and if so submitted shall be
finally settled by, arbitration in accordance with the Commercial Arbitration
Rules (the "Rules") of the American Arbitration Association, and judgment upon

be lawfully waived may be waived in writing at any time by the party which is
entitled to the benefits thereof. Any waiver of any of the provisions of this
Agreement by any party hereto shall be binding only if set forth in an
instrument in writing signed on behalf of such party. No failure to enforce any
provision of this Agreement shall be deemed to or shall constitute a waiver of
such provision and no waiver of any of the provisions of this Agreement shall be
deemed to or shall constitute a waiver of any other provision hereof (whether or
not similar) nor shall such waiver constitute a continuing waiver.
