            Section 5.2 Perfection of Security Interests.

                        (a) Borrower and each Guarantor irrevocably and
            unconditionally authorizes Lender (or its agent) to file at any time
            and from time to time such financing statements with respect to the
            Collateral naming Lender or its designee as the secured party and
            Borrower or any Guarantor, as the case may be, as Lender may
            require, and including any other information with respect to
            Borrower or any Guarantor or otherwise required by part 5 of Article
            9 of the Uniform Commercial Code of such jurisdiction as Lender may
            determine, together with any amendment and continuations with
            respect thereto, which authorization shall apply to all financing
            statements filed on, prior to or after the date hereof. Borrower and
            each Guarantor hereby ratifies and approves all financing statements
            naming Lender or its designee as secured party and Borrower or any
            Guarantor, as the case may be, as debtor with respect to the
            Collateral (and any amendments with respect to such financing
            statements) filed by or on behalf of Lender prior to the date hereof
            and ratifies and confirms the authorization of Lender to file such
            financing statements (and amendments, if any). Borrower and each
            Guarantor hereby authorizes Lender to adopt on behalf of Borrower or
            any such Guarantor, as the case may be, any symbol required for
            authenticating any electronic filing. In the event that the
            description of the Collateral in any financing statement naming
            Lender as the secured party and Borrower and any Guarantor, as the
            case may be, as debtor includes assets and properties of Borrower
            that do not at any time constitute Collateral, whether hereunder,
            under any of the other Financing Agreements or otherwise, the filing
            of such financing statement shall nonetheless be deemed authorized
            by such Borrower to the extent of the Collateral included in such
            description and it shall not render the financing statement
            ineffective as to any of the Collateral or otherwise affect the
            financing statement as it applies to any of the Collateral. In no
            event shall Borrower or any Guarantor at any time file, or permit or
            cause to be filed, any correction statement or termination statement
            with respect to any financing statement (or amendment or
            continuation with respect thereto) naming Lender or its designee as
            secured party and Borrower or any Guarantor, as debtor.

                        (b) Neither Borrower nor any Guarantor has any chattel
            paper (whether tangible or electronic) or instruments constituting
            Collateral as of the date of Amendment No. 17, except with respect
            to loans to employees permitted under Section 9.10(p) hereof. In the
            event that Borrower or any Guarantor shall be entitled to or shall
            receive any chattel paper or instrument after the date hereof
            constituting Collateral, Borrower or such Guarantor shall promptly
            notify Lender thereof in writing. Promptly upon the receipt thereof
            by or on behalf of Borrower or any Guarantor (including by any agent
            or representative), Borrower or such Guarantor shall deliver, or
            cause to be delivered to Lender, all tangible chattel paper and
            instruments constituting Collateral that Borrower or such Guarantor
            may at any time acquire, accompanied by such instruments of transfer
            or assignment duly executed in blank as Lender may from time to time
            specify, in each case except as Lender may otherwise agree. At
            Lender's option, Borrower and each Guarantor shall, or Lender may at
            any time on behalf of
<PAGE>
            Borrower or any Guarantor, as the case may be, cause the original of
            any such instrument or chattel paper to be conspicuously marked in a
            form and manner acceptable to Lender with the following legend
            referring to chattel paper or instruments as applicable: "This
            [chattel paper][instrument] is subject to the security interest of
            Congress Financial Corporation , as Lender and any sale, transfer,
            assignment or encumbrance of this [chattel paper][instrument]
            violates the rights of such secured party."

                        (c) In the event that Borrower or any Guarantor shall at
            any time hold or acquire an interest in any electronic chattel paper
            or any "transferable record" (as such term is defined in Section 201
            of the Federal Electronic Signatures in Global and National Commerce
            Act or in Section 16 of the Uniform Electronic Transactions Act as
            in effect in any relevant jurisdiction) constituting Collateral,
            Borrower or such Guarantor, as the case may be, shall promptly
            notify Lender thereof in writing. Promptly upon Lender's request,
            Borrower or such Guarantor shall take, or cause to be taken, such
            actions as Lender may reasonably request to give Lender control of
            such electronic chattel paper under the UCC and control of such
            transferable record under Section 201 of the Federal Electronic
            Signatures in Global and National Commerce Act or, as the case may
            be, Section 16 of the Uniform Electronic Transactions Act, as in
            effect in such jurisdiction.

                        (d) Neither Borrower nor any Guarantor has any deposit
            accounts as of the date of Amendment No. 17, except as set forth in
            Schedule 6.3 to Amendment No.17. Borrower nor any Guarantor shall,
            directly or indirectly, after the date hereof open, establish or
            maintain any deposit account into which (i) proceeds of Receivables
            or any of the other Collateral or (ii) proceeds of loans, advances
            or other financial accommodations made or provided by Lender or its
            Affiliates to or for the benefit of Borrower or its Affiliates or
            (iii) proceeds of loans, advances or other financial accommodations

            Credit Accommodations, will be deposited, unless each of the
            following conditions is satisfied: (i) Lender shall have received
            not less than five (5) Business Days prior written notice of the
            intention of such Borrower to open or establish such account which
            notice shall specify in reasonable detail and specificity acceptable
            to Lender the name of the account, the owner of the account, the
            name and address of the bank at which such account is to be opened
            or established, the individual at such bank with whom such Borrower
            is dealing and the purpose of the account, (ii) the bank where such
            account is opened or maintained shall be acceptable to Lender, and
            (iii) on or before the opening of such deposit account, such
            Borrower shall, as Lender may specify, either (A) deliver to Lender
            a deposit account control agreement with respect to such deposit
            account duly authorized, executed and delivered by Borrower or such
            Guarantor and the bank at which such deposit account is opened and
            maintained or (B) arrange for Lender to become the customer of the
            bank with respect to the deposit account on terms and conditions
            acceptable to Lender. The terms of this subsection (d) shall not
            apply to deposit accounts specifically and exclusively used for
            payroll, payroll taxes and other employee wage and benefit payments
            to or for the benefit of any Borrower's salaried employees.

                        (e) Neither Borrower nor any Guarantor owns or holds,
            directly or indirectly, beneficially or as record owner or both, any
            investment property, as of the date of Amendment No.17, or have any
            investment account, securities account, commodity account or other
            similar account with any bank or other financial institution or
            other securities intermediary or commodity intermediary as of the
            date of Amendment No.17.

                        (f) Neither Borrower nor any Guarantor is the
            beneficiary or otherwise entitled to any right to payment under any
            letter of credit, banker's acceptance or similar instrument as of
            the date of Amendment No.17. In the event that Borrower or any
            Guarantor shall be entitled to
<PAGE>
            or shall receive any right to payment under any letter of credit,
            banker's acceptance or any similar instrument, whether as
            beneficiary thereof or otherwise after the date hereof, Borrower or
            such Guarantor shall promptly notify Lender thereof in writing.
            Borrower or such Guarantor shall immediately, as Lender may specify,
            either (i) deliver, or cause to be delivered to Lender, with respect
            to any such letter of credit, banker's acceptance or similar
            instrument, the written agreement of the issuer and any other
            nominated person obligated to make any payment in respect thereof
            (including any confirming or negotiating bank), in form and
            substance satisfactory to Lender, consenting to the assignment of
            the proceeds of the letter of credit to Lender by Borrower or such
            Guarantor and agreeing to make all payments thereon directly to
            Lender or as Lender may otherwise direct or (ii) cause Lender to
            become, at Borrower's expense, the transferee beneficiary of the
            letter of credit, banker's acceptance or similar instrument (as the
            case may be).

                        (g) Neither Borrower nor any Guarantor has any
            commercial tort claims in excess of $10,000 as of the date of
            Amendment No. 17. In the event that Borrower or any Guarantor shall
            at any time after the date of Amendment No. 17 have any commercial
            tort claims (for which the amount of the claim of Borrower or
            Guarantor has a value in excess of $10,000), such Borrower shall
            promptly notify Lender thereof in writing, which notice shall (i)
            set forth in reasonable detail the basis for and nature of such
            commercial tort claim and (ii) include the express grant by Borrower
            or such Guarantor to Lender of a security interest, in such
            commercial tort claim (and the proceeds thereof). In the event that
            such notice does not include such grant of a security interest, the
            sending thereof by Borrower or such Guarantor to Lender shall be
            deemed to constitute such grant to Lender. Upon the sending of such
            notice, any commercial tort claim described therein shall constitute
            part of the Collateral and shall be deemed included therein. Without
            limiting the authorization of Lender provided in Section 5.2(a)
            hereof or otherwise arising by the execution by Borrower or
            Guarantor of this Agreement or any of the other Financing
            Agreements, Lender is hereby irrevocably authorized from time to
            time and at any time to file such financing statements naming Lender
            or its designee as secured party and Borrower and each Guarantor, as
            debtor, or any amendments to any financing statements, covering any
            such commercial tort claim as Collateral. In addition, Borrower and
            each Guarantor shall promptly upon Lender's request, execute and
            deliver, or cause to be executed and delivered, to Lender such other
            agreements, documents and instruments as Lender may require in
            connection with such commercial tort claim.

                        (h) Neither Borrower nor any Guarantor has any goods,
            documents of title constituting Collateral or other Collateral in
            the custody, control or possession of a third party as of the date
            of Amendment No.17 except for goods in transit to a location of
            Borrower or any Guarantor permitted herein in the ordinary course of
            business of Borrower and Guarantors in the possession of the carrier
            transporting such goods. In the event that any goods, documents of
            title constituting Collateral or other Collateral are at any time
            after the date hereof in the custody, control or possession of any
            other person, Borrower shall promptly notify Lender thereof in
            writing. Promptly upon Lender's request, Borrower and each Guarantor
            shall deliver to Lender a Collateral Access Agreement duly
            authorized, executed and delivered by such person and Borrower or
            such Guarantor.

                        (i) Borrower and Guarantors shall take any other actions
            reasonably requested by Lender from time to time to cause the
            attachment, perfection and first priority of, and the ability of
            Lender to enforce, the security interest of Lender in any and all of
            the Collateral, including, without limitation, (i) executing,
            delivering and, where
<PAGE>
            appropriate, filing financing statements and amendments relating
            thereto under the UCC or other applicable law, to the extent, if
            any, that Borrower's or such Guarantor's signature thereon is
            required therefor, (ii) causing Lender's name to be noted as secured
            party on any certificate of title for a titled good constituting
            Collateral if such notation is a condition to attachment, perfection
            or priority of, or ability of Lender to enforce, the security
            interest of Lender in such Collateral, (iii) complying with any
            provision of any statute, regulation or treaty of the United States
            as to any Collateral if compliance with such provision is a
            condition to attachment, perfection or priority of, or ability of
            Lender to enforce, the security interest of Lender in such
            Collateral, (iv) obtaining the consents and approvals of any
            governmental authority or third party, including, without
            limitation, any consent of any licensor, lessor or other person
            obligated on Collateral, and taking all actions required by any
            earlier versions of the UCC or by other law, as applicable in any
            relevant jurisdiction."

            exceed $85,000,000, less the aggregate amount of all repayments or
            redemptions, whether optional or mandatory, in respect thereof, plus
            interest (and capitalized interest) thereon at the rate provided for
            in the New Note Agreements as in effect on the Consummation Date,

(i)                     the financing arrangements evidenced by the Financing

         at a purchase price per share equal to $100 as increased by 10% per
         annum compounded quarterly beginning on the Closing Date and accruing
         daily through the date of the purchase of such shares (the "TRANCHE A

         Shares then available to it.

                  (c) For purposes of this Section 2.3, "PRO RATA PORTION" means
         a number of Tranche A Shares or Tranche B Shares, as the case may be,

         any Additional Shares and (B) $100.00, and (ii) the denominator of

         to purchase Additional Shares pursuant to this Agreement may not be
         assigned without the prior written consent of a Majority Interest.

by the Company and the Investors do not, and the consummation by the Company and

notice or both, is likely to result in a default or loss of any right thereunder
or the creation of any Lien upon any of the assets or properties of the Company,
except, in the case of clause (b) and (c) above, for any such violations,
conflicts, breaches or accelerations which would not, individually or in the
aggregate, have a Material Adverse Effect.

         Section 7.5 Offering of Shares. Based in part on the representations
and warranties of the Investors in Article VIII, the offer, sale and issuance of
the Securities pursuant to this Agreement do not require registration of such
securities under the Securities Act or registration or qualification under any
applicable state "blue sky" or securities laws. The Company, directly or
indirectly, has not taken and will not take any action which would subject the
issuance or sale of any of the Securities to the provisions of Section 5 of the
Securities Act or violate the provisions of any securities, "blue sky" law or
similar law of any applicable jurisdiction.

                  (b) Such Investor understands that the Securities have not

                  (c) Such Investor understands that the Company is relying in

                  (d) Such Investor is an "accredited investor" as defined in
         Rule 501(a) under the Securities Act;

         substance that it may dispose of the Securities only pursuant to an
         effective registration statement under the Securities Act or an
         exemption therefrom, and it understands that the Company has no
         obligation or intention to register any of the Securities thereunder
         (except pursuant to the registration rights granted in the
         Securityholders Agreement); and

                  (g) Such Investor has been furnished by the Company all

                  (a) Such Investor has full power and authority to enter into
         and perform its obligations under this Agreement; and

                  (b) This Agreement has been duly authorized, executed and
         delivered by a Person authorized to do so, constitutes the legal, valid
         and binding obligation of such Investor and, except as may be affected

term or condition of its certificate of incorporation or bylaws, or partnership
agreement or other organizational document, as applicable, or any agreement or
other instrument to which such Investor is a party or by which such Investor is
bound.

         Section 8.4 Other Agreements. Such Investor has not entered into any

applicable Required Consents set forth on Schedule 10.12, none of the RMG
Contribution, the execution or delivery by RMG of this Agreement or any Related
Agreement to which it is a party, or the consummation of the agreements and
transactions contemplated by this Agreement or any such Related Agreement

production or similar arrangement to deliver gas or other minerals produced from
or allocated to any of the RMG Contributed Assets at some future time without
receiving full payment therefor at the time of delivery. Except as disclosed on
Schedule 10.13, there are no material gas imbalances as between RMG and any
third party with respect to operations relating to the RMG Contributed Assets.

         Section 10.14 Change in Condition. There has occurred no physical

                                   TERMINATION

         Section 12.1 Termination. This Agreement may be terminated prior to the
Closing:

                  (a) by mutual agreement of the parties hereto;

                  (b) by any Investor in the event of a breach by any other
         Investor of any representation or warranty contained in this Agreement
         or any covenant or agreement required by the terms of this Agreement to
         be performed prior to the Closing Date which would give rise to the
         failure of a condition set forth in Article IV which cannot be cured
         or, if curable, has not been cured within 15 Business Days following
         receipt by the breaching party of written notice of such breach;

                  (c) by any Investor if a court of competent jurisdiction or
         other Governmental Entity shall have issued an order, decree or ruling
         or taken any other action (which order, decree or ruling the Company
         and the Investors shall use all commercially reasonable efforts to
         lift), in each case permanently restraining, enjoining, or otherwise
         prohibiting the transactions contemplated by this Agreement, and such
         order, decree, ruling or other action shall have become final and
         nonappealable; provided, however, that the right to terminate this
         Agreement under this Section 12.1(c) shall not be available to any
         party whose breach of this Agreement has been the cause of, or resulted
         in, such order, decree, ruling or other action; or

                  (d) by any Investor if the Closing shall not have occurred
         within 45 days of the date hereof, provided, however, that the right to
         terminate this Agreement under this Section 12.1(d) shall not be
         available to any party whose breach of this Agreement has been the
         cause of, or resulted in, the failure of the Closing Date to occur
         within such period.

         Section 12.2 Effect of Termination. In the event of the termination of
this Agreement, written notice thereof shall be given to all other parties

                                  MISCELLANEOUS

         Section 13.1 Indemnification.

                  (a) Subject to the limitations set forth herein, each of CCBM
         and RMG severally agrees to indemnify and hold the Company and the
         other Investors harmless from and against any liabilities, claims,
         losses, damages, costs and expenses of any kind (including, without
         limitation, the reasonable fees and disbursements of the Company's
         counsel and counsel to each of the Investors in connection with any
         investigative, administrative or judicial proceeding, whether or not
         the Company or either other Investor is designated as a party thereto)
         that may be incurred by the Company or either other Investor, relating
         to or arising out of (i) any breach of the representations and
         warranties made by such Contributing Party in Article IX and Article X
         hereof or, with respect to the representations made in Section 9.9 and
         Section 10.9, any breach which cannot be cured or, if curable, has not
         been cured within 60 calendar days following receipt by the breaching
         party of written notice of such breach, (ii) any operation of assets of
         such Contributing Party not contributed to the Company under this
         Agreement, (iii) any Excluded CCBM Liabilities (in the case of CCBM's
         obligation of indemnification) or Excluded RMG Liabilities (in the case
         of RMG's obligation of indemnification), as the

                                       44
<PAGE>
         case may be, or (iv) ownership or operation of the CCBM Contributed
         Assets and the RMG Contributed Assets by CCBM and RMG, respectively,
         prior to the Closing Date including any liabilities arising with
         respect to such period (collectively, the "CLAIMS").

                  (b) Notwithstanding the provisions of this Section 13.1, (i)
         neither Indemnifying Party (as defined below) shall be required to
         indemnify or hold harmless any of the Indemnified Parties (as defined
         below) on account of any Claims under clause (i) of Section 13.1(a)
         unless and until the aggregate liability of such Indemnifying Party in
         respect of all such Claims exceeds the Threshold Amount; provided,
         however, that once such aggregate Claims exceed the Threshold Amount,
         the Indemnifying Party shall be required to indemnify and hold harmless
         the Indemnified Parties to the fullest extent permitted by law from all
         such Claims, excluding those within the Threshold Amount and (ii)
         neither Indemnifying Party's aggregate liability in respect of all such
         Claims under clause (i) of Section 13.1(a) will exceed the Ceiling
         Amount.

                  (c) NO PARTY HERETO (OR ITS AFFILIATES) SHALL HAVE THE RIGHT
         TO INDEMNIFICATION HEREUNDER FOR ANY CONSEQUENTIAL, EXEMPLARY, SPECIAL,
         INCIDENTAL, SPECULATIVE, TREBLE OR PUNITIVE DAMAGES (INCLUDING ANY LOSS
         OF EARNINGS OR PROFITS, LOSS OF REVENUE OR INCOME, COST OF CAPITAL OR
         LOSS OF BUSINESS REPUTATION OR OPPORTUNITY) SUFFERED BY SUCH PARTY
         UNLESS SUCH DAMAGES WERE INCURRED BY A THIRD PARTY AND ARE THE SUBJECT
         OF A THIRD PARTY CLAIM FOR WHICH A PARTY HERETO MAY OTHERWISE BE
         INDEMNIFIED PURSUANT HERETO.

                  (d) THE PARTIES HERETO INTEND THAT THE INDEMNITIES SET FORTH
         IN SECTION 13.2(a) BE CONSTRUED AND APPLIED AS

                                       45
<PAGE>

         WRITTEN ABOVE NOTWITHSTANDING ANY RULE OF CONSTRUCTION TO THE CONTRARY.
         WITHOUT LIMITING THE FOREGOING, THE INDEMNITIES SHALL APPLY
         NOTWITHSTANDING ANY STATE'S "EXPRESS NEGLIGENCE RULE" OR SIMILAR RULE
         THAT WOULD DENY COVERAGE BASED ON AN INDEMNITEE'S SOLE, CONCURRENT OR
         CONTRIBUTORY ACTIVE OR PASSIVE NEGLIGENCE OR GROSS NEGLIGENCE OR STRICT
         LIABILITY. IT IS THE INTENT OF THE PARTIES THAT, TO THE EXTENT PROVIDED
         IN SECTION 13.2(a), THE INDEMNITIES SET FORTH HEREIN SHALL APPLY TO AN
         INDEMNITEE'S SOLE, CONCURRENT OR CONTRIBUTORY ACTIVE OR PASSIVE
         NEGLIGENCE, GROSS NEGLIGENCE OR STRICT LIABILITY. THE PARTIES AGREE
         THAT THIS PROVISION IS "CONSPICUOUS" FOR PURPOSES OF ALL STATE LAWS.

         Section 13.2 Indemnification Procedures.

                  (a) Any Person seeking indemnification under Section 13.1 (the
         "INDEMNIFIED PARTY") with respect to a Claim that is not a Third Party
         Claim shall commence and resolve such Claim solely in accordance with
         the dispute resolution procedures set forth in Section 13.3.

                  (b) If any Third Party Claim is asserted against any
         Indemnified Party and such Indemnified Party intends to seek
         indemnification hereunder from a party to this Agreement (the
         "INDEMNIFYING PARTY"), then such Indemnified Party shall give notice of
         the Third Party Claim to the Indemnifying Party as soon as practicable
         after the Indemnified Party has reason to believe that the Indemnifying
         Party will have an indemnification obligation with respect to such
         Third Party Claim and shall provide the Indemnifying Party with all
         papers served with respect to such Third Party Claim. Such notice shall
         describe in reasonable detail the nature of the Third Party Claim, an
         estimate of the amount of damages attributable to the Third Party Claim
         and the basis of the Indemnified Party's request for indemnification
         under this Agreement. The failure of the Indemnified Party to so notify
         the Indemnifying Party of the Third Party Claim shall not relieve the
         Indemnifying Party from any duty to indemnify hereunder unless and to
         the extent that the Indemnifying Party demonstrates that the failure of
         the Indemnified Party to promptly notify it of such Third Party Claim
         materially prejudiced its ability to defend such Third Party Claim;
         provided, that the failure of the Indemnified Party to notify the
         Indemnifying Party shall not relieve the Indemnifying Party from any
         liability which it may have to the Indemnified Party otherwise than
         under this Agreement. Thereafter, the Indemnified Party shall deliver
         to the Indemnifying Party, within five Business Days after the
         Indemnified Party's receipt thereof, copies of all notices and
         documents (including court papers) received by the Indemnified Party
         relating to the Third Party Claim.

                  (c) The Indemnifying Party shall have the right to participate
         in, or assume control of, and the Indemnifying Party's insurance
         carrier shall have the right to participate in, the defense of the
         Third Party Claim at its own expense by giving prompt written notice to
         the Indemnified Party, using counsel of its choice reasonably
         acceptable

                                       46
<PAGE>

         to the Indemnified Party. If it elects to assume control of the defense
         of such Third Party Claim, the Indemnifying Party shall defend such
         Third Party Claim by promptly and vigorously prosecuting all
         appropriate proceedings to a final conclusion or settlement. After
         notice from the Indemnifying Party to the Indemnified Party of its
         election to assume the defense of such Third Party Claim, the
         Indemnified Party shall have the right to participate in the defense of
         the Third Party Claim using counsel of its choice, but the Indemnifying
         Party shall not be liable to the Indemnified Party hereunder for any
         legal or other expenses subsequently incurred by the Indemnified Party
         in connection with its participation in the defense thereof unless (i)
         the employment thereof has been specifically authorized in writing by
         the Indemnifying Party, (ii) the Indemnifying Party fails to assume the
         defense or diligently prosecute the Third Party Claim or (iii) there
         shall exist or develop a conflict that would ethically prohibit counsel
         to the Indemnifying Party from representing the Indemnified Party. If
         requested by the Indemnifying Party, the Indemnified Party agrees to
         cooperate with the Indemnifying Party and its counsel in contesting any
         Third Party Claim that the Indemnifying Party elects to contest,
         including the making of any related counterclaim against the Third
         Party asserting the Third Party Claim or any cross-complaint against
         any Person, in each case only if and to the extend that any such
         counterclaim or cross-complaint arises from the same actions or facts
         giving rise to the Third Party Claim. The Indemnifying Party shall have
         the right, acting in good faith and with due regard to the interests of
         the Indemnified Party, to control all decisions regarding the handling
         of the defense without the consent of the Indemnified Party, but shall
         not have the right to admit liability with respect to, or compromise,
         settle or discharge any Third Party Claim or consent to the entry of
         any judgment with respect to such Third Party Claim without the consent
         of the Indemnified Party, which consent shall not be unreasonably
         withheld, unless such settlement, compromise or consent includes an
         unconditional release of the Indemnified Party from all liability and
         obligations arising out of such Third Party Claim and which would not
         otherwise adversely affect the Indemnified Party.

                  (d) If the Indemnifying Party fails to assume the defense of a
         Third Party Claim within 30 days after receipt of written notice of the
         Third Party Claim, then the Indemnified Party shall have the right to
         defend the Third Party Claim by promptly and vigorously prosecuting all
         appropriate proceedings to a final conclusion or settlement. The
         Indemnifying Party shall have the right to participate in the defense
         of the Third Party Claim using counsel of its choice, but the
         Indemnified Party shall not be liable to the Indemnifying Party
         hereunder for any legal or other expenses incurred by the Indemnifying
         Party in connection with its participation in the defense thereof. If
         requested by the Indemnified Party, the Indemnifying Party agrees to
         cooperate with the Indemnified Party and its counsel in contesting any
         Third Party Claim that the Indemnified Party elects to contest,
         including the making of any related counterclaim against the Third
         Party asserting the Third Party Claim or any cross-complaint against
         any Person, in each case only if and to the extent that any such
         counterclaim or cross-complaint arises from the same actions or facts
         giving rise to the Third Party Claim. The Indemnified Party shall have
         the right, acting in good faith and with due regard to the interests of
         the Indemnifying Party, to control all decisions regarding the handling
         of the defense without the consent of the Indemnifying Party, but shall
         not have the right to compromise or settle any Third Party Claim or
         consent to the entry of any judgment with

                                       47
<PAGE>

         respect to such Third Party Claim without the consent of the
         Indemnifying Party, which consent shall not be unreasonably withheld,
         unless such settlement compromise or consent includes an unconditional
         release of the Indemnifying Party from all liability and obligations
         arising out of such Third Party Claim.

                  (e) In the event an Indemnifying Party is determined to be
         liable with respect to any Claim pursuant to Section 13.3, such
         Indemnifying Party, within five Business Days after any such
         determination, shall pay to the Company in cash the full amount for
         which it is determined liable (an "AWARD"); provided, however, in lieu
         of any such cash payment the Indemnifying Party may, at its option,
         tender to the Company all of its right, title and interest in and to
         that number of shares of Common Stock (rounded to the nearest whole
         share) equal to the Award divided by $100, free and clear of all
         Encumbrances which, if accepted by the Company shall constitute a full
         accord and satisfaction with respect to the Award.

         Section 13.3 Dispute Resolution.

                  (a) Any controversy, dispute or claim arising out of or
         relating to this Agreement or the Related Agreements, or the
         transactions contemplated thereby (a "DISPUTE") shall be resolved in
         accordance with this Section 13.3.

                  (b) Any party may give the other party written notice (a
         "DISPUTE NOTICE") of any Dispute which has not been resolved in the
         normal course of business. Within 15 Business Days after delivery of
         the Dispute Notice, the receiving party shall submit to the other party
         a written response (the "RESPONSE"). The Dispute Notice and the
         Response shall each include (i) a statement setting forth the position
         of the party giving such notice, a summary of the arguments supporting
         such position and, if applicable, the relief sought and (ii) the name
         and title of a senior manager of such party who has authority to settle
         the Dispute and will be responsible for the negotiations related to the
         settlement of the Dispute (the "SENIOR MANAGER").

                  (c) Within 10 days after delivery of the Response provided for
         in Section 13.3(b), the Senior Managers of both parties shall meet or
         communicate by telephone at a mutually acceptable time and place, and
         thereafter as often as they reasonably deem necessary, and shall
         negotiate in good faith to attempt to resolve the Dispute that is the
         subject of such Dispute Notice. If such Dispute has not been resolved
         within 30 days after delivery of the Dispute Notice, then the parties
         shall attempt to settle the Dispute pursuant to Section 13.3(d).

                  (d) In the event the Dispute has not been resolved within 30
         days after the delivery of the Dispute Notice, the Dispute shall be
         resolved by arbitration administered by the American Arbitration
         Association (the "AAA") in accordance with the terms of this Section
         13.3(d), the Commercial Arbitration Rules of the AAA, and, to the
         maximum extent applicable, the United States Arbitration Act. Judgment
         on any matter rendered by arbitrators may be entered in any court
         having jurisdiction. Any arbitration shall be conducted before three
         arbitrators. The arbitrators shall be individuals knowledgeable in the
         subject matter of the Dispute. Each party shall select one arbitrator
         and the two

                                       48
<PAGE>

         arbitrators so selected shall select the third arbitrator. If the third
         arbitrator is not selected within 30 Business Days after the request
         for an arbitration, then any party may request the AAA to select the
         third arbitrator. The arbitrators may engage engineers, accountants or
         other consultants they deem necessary to render a conclusion in the
         arbitration proceeding. To the maximum extent practicable, an
         arbitration proceeding hereunder shall be concluded within 90 Business
         Days of filing a Dispute with the AAA. Arbitration proceedings shall be
         conducted in Houston, Texas. Arbitrators shall be empowered to impose
         sanctions and to take such other actions as the arbitrators deem
         necessary to the same extent a judge could impose sanctions or take
         such other actions pursuant to the Federal Rules of Civil Procedure and
         applicable Law. At the conclusion of any arbitration proceeding, the
         arbitrators shall make specific written findings of fact and
         conclusions of law. The arbitrators shall have the power to award
         recovery of all costs and fees to the prevailing party. All fees of the
         arbitrators and any engineer, accountant or other consultant engaged by
         the arbitrators, shall be shared equally unless otherwise awarded by
         the arbitrators. Notwithstanding the foregoing, if the amount in
         controversy is less than $1,000,000, then, instead of selecting three
         arbitrators by the process described above, one arbitrator shall be
         selected in accordance with the rules of AAA. In this event the
         arbitration proceeding shall be conducted for all purposes as set forth
         in this Section 13.3(d), except that the proceeding shall be conducted
         by the one arbitrator, instead of the three.

                  (e) All negotiations between the Senior Managers pursuant to
         this Section 13.3 shall be treated as compromise and settlement
         negotiations. Nothing said or disclosed, nor any document produced, in
         the course of such negotiations that is not otherwise independently
         discoverable shall be offered or received as evidence or used for
         impeachment or for any other purpose in any current or future
         arbitration or litigation.

         Section 13.4 Consent to Amendments. This Agreement may be amended and
the observance of any term of this Agreement may be waived with (and only with)
the written consent of the Company and each Investor.

         Section 13.5 Survival of Representations and Warranties. Unless this
Agreement is terminated pursuant to Section 12.1, in which case the
representations and warranties do not survive termination, all representations
and warranties contained herein or made in writing by or on behalf of any party
to this Agreement in connection herewith shall survive the execution and
delivery of this Agreement until July 1, 2004, regardless of any investigation
made by or on behalf of any party. No party may bring any Claim based upon a
breach of the representations or warranties contained in this Agreement after
such date.

         Section 13.6 Successors and Assigns; No Third Party Benefit. All
covenants and agreements in this Agreement contained by or on behalf of the
parties hereto shall bind and inure to the benefit of the respective successors
and assigns of the parties hereto and, to the extent provided in this Agreement,
to the benefit of any future holders of Shares issued pursuant to this
Agreement, but in no event to the purchaser of Shares in any registered offering
under the Securities Act or any "brokers' transactions" effected pursuant to
Rule 144 of the Securities Act. Subject to the foregoing and except as provided
in Section 13.1, nothing in this Agreement shall confer upon any person or
entity not a party to this Agreement, or the legal representatives of

                                       49
<PAGE>

such person or entity, any rights or remedies of any nature or kind whatsoever
under or by reason of this Agreement. No transfer of Securities shall relieve
any party of its obligations hereunder, if the transferee of such Securities
does not perform any assumed obligation.
