Purchase Agreement) to which any of El Paso and the Relevant El Paso Parties is
a party will be duly executed and delivered by El Paso and such Relevant El Paso
Party and, subject to the due execution and delivery by the other parties
thereto, will, upon such due execution and delivery, constitute the legal, valid
and binding obligations of El Paso or such Relevant El Paso Party, as
applicable, enforceable against El Paso or such Relevant El Paso Party, as
applicable, in accordance with its terms, except as may be limited by any
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws

Parties is in compliance with all laws, rules, regulations and orders of any
Governmental Authority applicable to it or its property, except where the

Adverse Effect.

         (f) Litigation. There is no action, suit or proceeding pending, or, to
the knowledge of any Responsible Officer of El Paso, threatened, against or
involving El Paso or any Relevant El Paso Party in any court, or before any

reasonable judgment of El Paso (taking into account the exhaustion of all

affect the legality, validity, binding effect or enforceability against El Paso
or any Relevant El Paso Party of any Transaction Document to which it is a
party.

filed all tax returns required to be filed, and has duly paid and discharged all

         (h) ERISA.

                  (i) No ERISA Termination Event has occurred or is reasonably
         expected to occur with respect to any Plan which, with the giving of
         notice or lapse of time or both, would result in an aggregate liability
         of El Paso or any ERISA Affiliate that would exceed 10% of the Net
         Worth of El Paso.

                  (ii) Each Plan has complied with the applicable provisions of
         ERISA and the Code where the failure to so comply would reasonably be
         expected to result in an aggregate liability that would exceed 10% of
         the Net Worth of El Paso.

                  (iii) The statement of assets and liabilities of each Plan and
         the statements of changes in fund balances and in financial position,
         or the statement of changes in net assets available for plan benefits,
         for the most recent plan year for which an accountant's report with
         respect to such Plan has been prepared, fairly present the financial
         condition of such Plan as at such date and the results of operations of
         such Plan for the plan year ended on such date.

                  (iv) Neither El Paso nor any ERISA Affiliate has incurred, or
         is reasonably expected to incur, any Withdrawal Liability to any
         Multiemployer Plan which, when aggregated with all other amounts
         required to be paid to Multiemployer Plans in connection with
         Withdrawal Liability (as of the date of determination), would exceed
         10% of the Net Worth of El Paso.

                  (v) Neither El Paso nor any ERISA Affiliate has received any
         notification that any Multiemployer Plan is in reorganization,
         insolvent or has been terminated, within the meaning of Title IV of
         ERISA, and no Multiemployer Plan is reasonably expected to be in
         reorganization, to become insolvent or to be terminated within the
         meaning of Title IV of ERISA, the effect of which would result in an
         aggregate liability of El Paso or any ERISA Affiliate that would exceed
         10% of the Net Worth of El Paso.

<PAGE>

disclosed on Schedule I) and (iv) do not contravene, or constitute a default
under, any provision of Applicable Law in effect on October 25, 2001 or on the
Closing Date, as applicable, or any Gemstone Party's Organizational Documents,
or of any agreement or other instrument binding upon a Gemstone Party or violate
or contravene any of the terms, conditions or provisions of any order, judgment,
decree or ruling of any court, arbitrator or Governmental Authority applicable
to a Gemstone Party, or result in the creation or imposition of any Lien on any
asset of a Gemstone Party, except for (A) Permitted Liens, in the case of
Garnet, Diamond, Diamond Holdings, Amethyst, Aquamarine or Peridot, (B)
Permitted Liens of the type described in clause (iii) of the definition thereof,
in the case of Investor, the Co-Issuer or the Share Trust and (C) Permitted
Liens of the type described in clauses (i) and (iii) of the definition thereof,
in the case of Topaz, Emerald and Citrine.

         (f) Binding Effect. Each of the Transaction Documents to which any
Gemstone Party is a party has been or on the Closing Date will be duly executed
and delivered by such Gemstone Party and, subject to the due execution and
delivery by the other parties thereto, each of the Transaction Documents (other
than the Note Purchase Agreement) to which any Gemstone Party is a party
constitutes or will constitute (or in the case of the Notes, when duly
authenticated, issued, paid for and delivered in accordance with the Indenture
and the Note Purchase Agreement, will constitute) a legal, valid and binding
obligation of such Gemstone Party, enforceable against such Gemstone Party in
accordance with its terms except as the enforceability thereof may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and general equitable
principles (whether enforcement is sought by proceedings in equity or at law).

         (g) Security for the Notes. The Grant (as defined in the Indenture) of
the Security for the Notes securing the payment of the Secured Obligations (as
defined in the Indenture) for the benefit of the Indenture Trustee and the
Holders of the Notes will constitute a valid, first priority (subject to
Permitted Liens), perfected security interest in the Security for the Notes,
free and clear of any Lien or claims of any Person (other than Permitted Liens),
to the extent perfection can occur under Article 9 of the New York UCC by
possession, filing of a financing statement or control of a securities account.
Following such perfection, such security interest will be enforceable as such
subject to Permitted Liens against all creditors of Investor and any Persons
purporting to purchase any of the Security for the Notes from Investor, except
in each case as enforcement may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and general equitable principles (whether
enforcement is sought by proceedings in equity or at law) and other than as
permitted by the Transaction Documents. No Gemstone Party has executed any valid
financing statement covering the Indenture Trustee's interest in the Security
for the Notes that is on file in any public office other than the financing
statements, if any, filed pursuant to the Transaction Documents.

         (h) Security for the Emerald Loan. The Collateral Agreement will
create, as security for the obligations of Emerald purported to be secured
thereby, a valid, first priority (subject to Permitted Liens), perfected
security interest in the collateral described in the Collateral Agreement, free
and clear of any Lien or claims of any Person (other than Permitted Liens), to
the extent perfection can occur under Article 9 of the New York UCC by
possession, filing of a financing statement or control of a securities account.
Following such perfection, such security

                                       12
<PAGE>

interest will be enforceable as such (subject to Permitted Liens) against all
creditors of Emerald and any Persons purporting to purchase any of the
collateral described in the Collateral Agreement from Emerald, except in each
case as enforcement may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting the enforcement of creditors' rights
generally and general equitable principles (whether enforcement is sought by
proceedings in equity or at law) and other than as permitted by the Transaction
Documents. No Gemstone Party has executed any valid financing statement covering
the Collateral Agent's interest in the collateral described in the Collateral
Agreement that is on file in any public office other than the financing
statements, if any, filed pursuant to the Transaction Documents.

         (i) No Consents. (i) The execution, delivery and performance by each
Gemstone Party of each Transaction Document (other than the Note Purchase
Agreement) to which such Gemstone Party is a party do not require the consent or
the approval or authorization of, or any filing, registration or qualification
with, any Person or any Governmental Authority on the part of such Gemstone
Party as a condition to such execution, delivery and performance by it as and
when required that has not been obtained, given or taken except (i) for filings
of financing statements, and the entry into any requisite control agreements, to
perfect the security interests contemplated by the Indenture and the Emerald
Loan Agreement or the Collateral Agreement, (ii) as disclosed on Schedule I and
(iii) where the failure to obtain such consent, approval or authorization, or
make such filing, registration or qualification, would not reasonably be
expected to have, in the case of Topaz, Emerald, Citrine, Garnet, Diamond,
Diamond Holdings, Amethyst, Aquamarine or Peridot, an Aggregate JV Material
Adverse Effect or an Issuer Material Adverse Effect.

         (ii) The offering of the Securities by Investor and the Co-Issuer and
the creation of the Security for the Notes do not require the consent or the
approval or authorization of, or filing, registration or qualification with, any
Person or any Governmental Authority on the part of Investor or the Co-Issuer
which has not been obtained, given or taken except (i) for filings of financing
statements, and the entry into any requisite control agreements, to perfect the
security interests contemplated by the Indenture and (ii) where the failure to
obtain such consent, approval or authorization, or filing, registration or
qualification would not have an Issuer Material Adverse Effect. Neither the
issuance or delivery of the Notes to the Initial Purchasers, nor the
consummation of any other of the transactions contemplated herein, nor
compliance with the provisions of the Indenture, will conflict with or result
in, the breach of any term or provision of any agreements to which Investor or
the Co-Issuer is a party, or constitute a violation of any Applicable Law.

         (j) Litigation. There is no Proceeding pending against or, after
reasonable inquiry, to the actual knowledge of any Responsible Officer of El
Paso, threatened against Investor, the Co-Issuer, Diamond, Diamond Holdings,
Aquamarine, Peridot or the Share Trust before any Governmental Authority. There

of El Paso, threatened against Topaz, Emerald, Citrine, Garnet or Amethyst
before any Governmental Authority.

         (k) Tax Claims. There is no Tax claim pending against or, after
reasonable inquiry, to the actual knowledge of any Responsible Officer of El
Paso, threatened against Investor, the Co-Issuer, Diamond, Diamond Holdings,
Aquamarine, Peridot or the Share Trust. There is no

                                       13
<PAGE>

Tax claim pending against or, to the knowledge of any Responsible Officer of El
Paso after reasonable inquiry, threatened against Topaz, Emerald, Citrine,
Garnet or Amethyst. Investor and the Co-Issuer have each paid all Taxes that
they are required to have paid prior to October 25, 2001 and prior to the
Closing Date.

         (l) Not an Investment Company. None of the Gemstone Parties will be
required to be registered as an "investment company" within the meaning of the
Investment Company Act, and none of the Gemstone Parties will become such as a
result of the issuance and sale of the Securities or the other transactions
contemplated by the Transaction Documents.

         (m) Liens. There are no Liens of any kind (other than Permitted Liens
described under clause (iii) of the definition thereof) affecting title to any
of the assets or rights of any of Investor, the Co-Issuer or the Share Trust
under any Transaction Documents. There are no Liens of any kind (other than
Permitted Liens) affecting title to any of the assets or rights of Garnet,
Diamond, Diamond Holdings, Amethyst, Aquamarine or Peridot under any Transaction
Documents. There are no Liens of any kind (other than Permitted Liens described
under clauses (i) and (iii) of the definition thereof) affecting title to any of
the assets or rights of any of Topaz, Emerald or Citrine under any Transaction
Documents.

         (n) Compliance. None of the Gemstone Parties is in breach or violation
of or in default (nor, after reasonable inquiry, to the actual knowledge of any
Responsible Officer of El Paso, has an event occurred that with notice or lapse
of time or both would constitute a default) under the terms of (i) its
Organizational Documents, (ii) any of the Transaction Documents or any other
agreements to which any Gemstone Party is a party, or (iii) any Applicable Law,
the default in or the breach or violation of which in the case of clauses (ii)
and (iii) above, would reasonably be expected to have (A) an Aggregate JV
Material Adverse Effect or an Issuer Material Adverse Effect, in the case of
Topaz, Emerald, Citrine, Garnet, Diamond, Diamond Holdings, Amethyst, Aquamarine
or Peridot or (B) an Issuer Material Adverse Effect, in the case of Investor or
the Co-Issuer.

         (o) Margin Compliance. No part of the proceeds of the sale of the
Securities will be used, directly or indirectly, for the purpose of purchasing
or carrying any "margin stock" within the meaning of Regulations U and X of the
Board of Governors of the Federal Reserve System.

         (p) Indebtedness. None of the Gemstone Parties has created, assumed or
incurred any indebtedness in violation of its Organizational Documents or any
other Transaction Document.

to the Indenture Trustee a certificate in the form attached as Exhibit D either
certifying as to the absence or existence of any Note Trigger Event, any
Specified Equity Event, any Shareholder Trigger Event or El Paso Debt Obligation
Repayment Event or, if a Note Trigger Event, Specified Equity Event, Shareholder
Trigger Event or El Paso Debt Obligation Repayment Event exists, setting forth
the details thereof and the action El Paso has taken and proposes to take with
respect thereto and (ii) if no Financial Investments (other than Financial
Investments of the type described in clause (g) of the definition thereof) made
with Excess Securities Proceeds are held by the Securities Intermediary at the
times of such notice, or if the proceeds of the liquidation of such Financial
Investments by the Securities Intermediary are less than the amount of the
Capital Contribution requested by such notice, El Paso shall have the option of
prepaying El Paso Debt Security Notes to provide funds to make, or to pay the
balance of, such requested Capital Contributions to Diamond. Upon receipt by the
Indenture Trustee of the certificate described in clause (i) above, the
Indenture Trustee shall immediately require the Securities Intermediary to sell
or otherwise dispose of Financial Investments referred to in clauses (a) through

Investments) to Diamond. The Indenture Trustee directs El Paso and the
Securities Intermediary (and shall so notify them) to pay the proceeds of the

         Section 5.4 Certain Acknowledgements and Agreements of Parties.

         (a) Treatment of Capital Contributions. The Class A Shareholder
acknowledges and agrees to the Capital Contributions made or deemed to have been
made under Sections 3.3(a)(ii), 3.3(a)(iii) or 3.3(a)(iv) of the Diamond LLC
Agreement, Sections 3.3(a)(ii) or 3.3(a)(iii) of the Garnet LLC Agreement and
Sections 3.3(a)(ii) or 3.3(b)(ii) of the Topaz LLC Agreement. The Class A
Shareholder further agrees that it will for all purposes treat any of such
deemed Capital Contributions as having been actually made by the Person deemed
to have made such Capital Contribution and received by the Person deemed to have
received such Capital Contribution, crediting and debiting relevant books,
records and accounts as would be necessary if such Capital Contributions had
actually been made and received. The Class A Shareholder shall not take a
position contrary to, or take any action inconsistent with, the treatment of
Capital Contributions as described in this Section 5.4(a) (other than as
required by the Transaction Documents). The Class A Shareholder shall take such
actions as is reasonably requested by El Paso to evidence the treatment of
Capital Contributions as described in this Section 5.4(a).

         (b) Performance by Indenture Trustee, Securities Intermediary and
Fiscal Agent of Certain Obligations. The Indenture Trustee, the Securities
Intermediary and the Fiscal Agent each agree to comply with its agreements set
forth in Sections 3.04 and 5.05 of the Indenture.

         (c) Political Risk Policy. (i) (i) If at any time an event occurs that
would result in a claim being available under the Political Risk Policy, then
the Class A Shareholder may (and, upon the request of El Paso, shall) promptly
make such a claim. The Class A Shareholder shall have the option of irrevocably
designating El Paso (or El Paso's designee) as the primary loss payee under the
Political Risk Policy with respect to such claim. Within 10 Business Days after
making such a claim, the Class A Shareholder will give El Paso written notice of
its intent to exercise such option and shall, within 15 Business Days after the
delivery of such notice, execute and deliver such further agreements,
instruments and other documents, and take such further actions, as may be
necessary or reasonably requested by El Paso to accomplish such designation as
primary loss payee. If the Class A Shareholder does not opt to irrevocably
designate El Paso (or El Paso's designee) as loss payee as set forth above
(unless the Class A Shareholder is prevented by Applicable Law from doing so),
then (a) the Foreign Risk Loss indemnity set forth in Section 6.1(c) will
terminate and El Paso will have no obligation under Section 6.1(c) from and
after such date and (b) El Paso's obligation to pay the premiums in connection
with the Political Risk Insurance will terminate.

                  (ii) If, on the date the Class A Shareholder receives a
         payment with respect to a claim made under the Political Risk Policy,
         the Class A Shareholder has received payments (excluding indemnity and
         expense reimbursement payments (other than payments received under
         Section 6.1(b), 6.1(c) or 6.1(d)) and, in the case of clause (a) below,
         any payments of Shareholder Yield or Default Yield already received)
         that, in the aggregate, equal or exceed (a) the Capital Price, if such
         date occurs prior to the Extension Period Commencement Date or (b) the
         Target IRR Amount, if such date occurs on or after the Extension Period
         Commencement Date, then, in each case, (1) the Class A Shareholder will
         promptly turn over such excess, if any, to El Paso (or El Paso's
         designee) or, to the extent indemnity or expense reimbursement payments
         are due and owed at such time under the Transaction Documents to the
         Class A Shareholder, an

                                       27
<PAGE>

         Equity Investor, a director of Investor or a director of Citrine (after
         the acceleration of the Emerald Loan) (and El Paso has been notified of
         such payments in writing), promptly after payment in full of such
         amounts, (2) the Class A Shareholder shall, within 15 Business Days
         after the receipt of such payments, execute and deliver such further
         agreements, instruments and other documents, and take such further
         actions, as may be necessary or reasonably requested by El Paso to
         irrevocably designate El Paso (or El Paso's designee) as the primary
         loss payee under the Political Risk Policy and (3) El Paso's obligation
         to pay the premiums in connection with the Political Risk Insurance
         will terminate.

                  (iii) If (a) the Purchase Option or the Retirement Option is
         made with respect to the Topaz Minority Member Interest and/or the
         Diamond Class A Member Interest, (b) the repurchase is made pursuant to
         Section 11.5(e) of the Diamond LLC Agreement and Section 11.5(e) of the
         Topaz LLC Agreement or (c) the Extension Period Termination Date occurs
         as a result of the occurrence of a Liquidating Event described in
         clause (e) of the definition thereof and sufficient funds are available
         to be applied under Section 12.2 of the Diamond LLC Agreement, Section
         12.2 of the Topaz LLC Agreement and Section 12.2 of the Garnet LLC
         Agreement to cause the Class A Shareholder to receive payments
         (excluding indemnity and expense reimbursement payments (other than
         payments received under Section 6.1(b), 6.1(c) or 6.1(d)) and, in the
         case of clause (1) below, any payments of Shareholder Yield or Default
         Yield already received), if such payments were distributed to the Class
         A Shareholder on the scheduled liquidation dates, equal to (1) the
         Capital Price if such Liquidating Event occurs prior to the Extension
         Period Commencement Date or (2) the Target IRR Amount if such
         Liquidating Event occurs on or after the Extension Period Commencement
         Date, then, in each case, (A) the Class A Shareholder shall, within 15
         Business Days after the receipt by Investor (or the Indenture Trustee
         or Fiscal Agent, as the case may be) of such payments or funds, execute
         and deliver such further agreements, instruments and other documents,
         and take such further actions, as may be necessary or reasonably
         requested by El Paso to irrevocably designate El Paso (or El Paso's
         designee) as the primary loss payee under the Political Risk Policy
         (and deliver evidence thereof to the Indenture Trustee) and (B) El
         Paso's obligation to pay the premiums in connection with the Political
         Risk Insurance will terminate. Until such time as the Class A
         Shareholder has designated El Paso (or El Paso's designee) as loss
         payee as required by this clause (iii) (whether as a result of the
         application of Applicable Law or otherwise), the Class A Shareholder
         will promptly turn over all proceeds it receives with respect to any
         claim made under the Political Risk Policy to El Paso (or El Paso's
         designee) and will (at El Paso's expense) diligently pursue any claim
         on behalf of El Paso made under the Political Risk Policy.

                  (iv) Within 15 Business Days after the Extension Period
         Termination Date occurs as a result of the occurrence of the events
         described in clause (a) of the definition thereof, (a) the Class A
         Shareholder shall execute and deliver such further agreements,
         instruments and other documents, and take such further actions, as may
         be necessary or reasonably requested by El Paso to irrevocably
         designate El Paso (or El Paso's designee) as the primary loss payee
         under the Political Risk Policy and (b) El Paso's obligation to pay the
         premiums in connection with the Political Risk Insurance will
         terminate.

<PAGE>

                  (v) If the Class B Shareholder exercises its Share Purchase
         Option in accordance with Section 7.1 of the Shareholders Agreement,
         then (A) the Class A Shareholder shall at El Paso's expense, within 15
         Business Days after its receipt of the Share Purchase Option Price,
         execute and deliver such further agreements, instruments and other
         documents, and take such further actions, as may be necessary or
         reasonably requested by El Paso to irrevocably designate El Paso (or El
         Paso's designee) as the primary loss payee under the Political Risk
         Policy (and deliver evidence thereof to the Indenture Trustee) and (B)
         El Paso's obligation to pay the premiums in connection with the
         Political Risk Insurance will terminate. Until such time as the Class A
         Shareholder has designated El Paso (or El Paso's designee) as loss
         payee as required by this clause (v) (whether as a result of the
         application of Applicable Law or otherwise), the Class A Shareholder
         will promptly turn over all proceeds it receives with respect to any
         claim made under the Political Risk Policy to El Paso (or El Paso's
         designee) and will (at El Paso's expense) diligently pursue any claim
         on behalf of El Paso made under the Political Risk Policy.

                  (vi) If the Class A Shareholder elects or is required to
         irrevocably designate El Paso (or El Paso's designee) as loss payee as
         set forth in this Section 5.4(c) and is prevented by Applicable Law
         from doing so, the Class A Shareholder will (at El Paso's expense)
         diligently pursue any claim on El Paso's behalf made under the
         Political Risk Policy and promptly turn over all proceeds it receives
         with respect to such claims to El Paso (or El Paso's designee).

                  (vii) The provisions of this Section 5.4(c) survive the
         termination of this Agreement.

                  (iv) any sale, transfer or holding of the Class A Shares being
         deemed to result in a non-exempt "prohibited transaction" under ERISA
         and/or Section 4975 of the Code due to any act or omission by El Paso
         or its Affiliates; provided that the Expense Indemnification set forth
         in this clause (iv) shall not apply to the Class A Shareholder or any
         Equity Investor to the extent that such "prohibited transaction"
         results from a breach by the Class A Shareholder or such Equity
         Investor of its representations, warranties or covenants contained in
         the Investment Certificate delivered by it pursuant to this Agreement
         and the Investor Shareholders Agreement or the Equity Investor

                  (vii) Documentary Taxes;

                  (viii) (A) the acquisition or ownership by Garnet or Amethyst

                  (ix) other than with respect to CSFB or to the extent arising
         out of or resulting from a breach of any representation, warranty,
         covenant or obligation of such Expense Indemnified Person, (A) the
         offer, sale or delivery of any of the Class A Shares, the Notes, the

         by the Closing Agreement; and

                  (x) the invalidity of El Paso's guaranty set forth in Section
         5.2 to the extent such invalidity is the result of the application of
         Applicable Law.

         (b) Covered Loss Indemnification. El Paso agrees (except as provided
below) to indemnify, protect, defend and hold harmless each Loss Indemnified
Person against Covered Losses directly or indirectly resulting from or
attributable to Expense Payments to the extent but only to the extent such
Expense Payments are paid or incurred by Topaz, Emerald, Citrine, Garnet,
Diamond, Diamond Holdings, Amethyst, Aquamarine, Peridot, any Subsidiary of
Amethyst, any Amethyst Minority Owned QEC, any Subsidiary of Aquamarine or any
Aquamarine Minority Owned QEC by reason of:

                  (i) (A) any act or omission constituting gross negligence or
         willful misconduct on the part of El Paso or any El Paso Party, (B) any
         breach of, failure to perform or observe, or other non-compliance with,
         any covenant, condition or agreement (without giving effect to any
         qualification with respect to the materiality thereof) to be performed
         by, or other obligation of, El Paso or any El Paso Party (other than
         the covenants of the Management Company under Section 2 or 3 of the
         Management Agreement) under any of the Transaction Documents, (C) any
         failure by the Management Company to perform its obligations under
         Section 2 or 3 of the Management Agreement in accordance with the
         standards set forth in Section 6.1 of the Management Agreement or (D)
         the breach of any representation or warranty (without giving effect to

         Peridot, the Management Company, any Subsidiary of Amethyst, any
         Amethyst Minority Owned QEC, any Subsidiary of Aquamarine or any
         Aquamarine Minority Owned QEC, except arising by reason of a
         Replacement Period Event; and

                  (iii) any Extraordinary Liabilities other than any
         Extraordinary Liabilities arising by reason of a Replacement Period
         Event;

provided that, to the extent any such Covered Loss directly or indirectly
results from or is attributable to any Excluded Items, this Section 6.1(b) shall
not apply and El Paso shall have no liability hereunder.

         Any amount payable pursuant to this Section 6.1(b) shall be payable on
the JV Final Payment Date with respect to (i) a liquidation of Topaz with
respect to amounts payable under

                                       32
<PAGE>

this Section 6.1(b) and attributable to Topaz, Emerald, Citrine, Garnet,
Diamond, Diamond Holdings, Amethyst, any Subsidiary of Amethyst, any Amethyst
Minority Owned QEC, Aquamarine, Peridot, any Subsidiary of Aquamarine or any
Aquamarine Minority Owned QEC or (ii) a liquidation of Diamond with respect to
amounts payable under this Section 6.1(b) and attributable to Diamond, Diamond
Holdings, Aquamarine, Peridot, any Subsidiary of Aquamarine or any Aquamarine
Minority Owned QEC (the "Covered Loss Indemnity Payment Date"). On the Covered
Loss Indemnity Payment Date, if there would, but for the payment provided for
pursuant to this Section 6.1(b), exist a Covered Loss, El Paso shall supply to
the Class A Shareholder and each Equity Investor computations setting forth in
reasonable detail the basis on which the amount payable pursuant to this Section
6.1(b) is determined. The provisions of Section 6.1(g) shall not apply to any
indemnity pursuant to this Section 6.1(b).

         (c) Foreign Risk Indemnification.

                  (i) FRCA Appraisal. Subject to Section 5.4(c)(i), at any time
         after any FRCA Appraisal Date the Class A Shareholder may elect to
         deliver written notice (a "FRCA Claim Notice") to El Paso of its
         intention to commence an appraisal (a "FRCA Appraisal") in accordance
         with this Section 6.1(c) and the FRCA Appraisal Procedures. Such FRCA
         Claim Notice must specify each FRCA Asset for which a FRCA Appraisal is
         then being requested. On or after the eleventh Business Day after such
         delivery to El Paso of a FRCA Claim Notice, the Class A Shareholder may
         commence an appropriate FRCA Appraisal with respect to each FRCA Asset
         properly specified in such FRCA Claim Notice to determine whether (A) a
         Cash Flow Foreign Risk Loss has occurred with respect thereto and (B)
         an Asset Foreign Risk Loss has occurred, but solely in respect of a
         FRCA Asset for which a FRCA Asset Sale has occurred on or prior to such
         FRCA Appraisal Date.

                  (ii) Foreign Risk Loss Determination. If it has been finally
         determined, in accordance with the appropriate FRCA Appraisal
         Procedures, that an Asset Foreign Risk Loss, Cash Flow Foreign Risk
         Loss or both, as applicable, exists with respect to a FRCA Asset
         specified in a FRCA Claim Notice, then the Foreign Risk Loss Balance
         shall be increased by the amount of such Asset Foreign Risk Loss, if
         any, and such Cash Flow Foreign Risk Loss, if any.

                  (iii) Foreign Risk Loss Payment. At any time that the Foreign
         Risk Loss Balance is greater than zero and a Foreign Risk Coverage
         Condition then continues to exist, El Paso agrees to pay (or cause to
         be paid) to Diamond in Dollars an amount equal to the lesser of (A) the
         full amount of the Foreign Risk Loss Balance and (B) the amount that:

                  (1)      in the case of a Foreign Risk Loss realized in
                           connection with any Garnet FRCA Property, would, if
                           immediately allocated pursuant to the Garnet LLC
                           Agreement, cause the aggregate amount of Net Losses
                           and Garnet Net Capital Loss allocated to the Garnet
                           Preferred Member to no longer exceed the aggregate
                           amount of Net Income and Garnet Net Capital Gain
                           allocated to the Garnet Preferred Member; and

                                       33
<PAGE>

                  (2)      in the case of a Foreign Risk Loss realized in
                           connection with any Diamond FRCA Property, would, if
                           immediately allocated pursuant to the Diamond LLC
                           Agreement, cause the aggregate amount of Net Losses
                           allocated to the Diamond Class A Member to no longer
                           exceed the aggregate amount of Net Income allocated
                           to the Diamond Class A Member.

         Any amounts payable pursuant to this Section 6.1(c)(iii) shall be
         payable on any day (the "Foreign Risk Loss Indemnity Payment Date") on
         or prior to the 10th Business Day after the receipt by El Paso of
         written notice that the amount of the Foreign Risk Loss Balance is
         greater than zero and that a Foreign Risk Coverage Condition exists;
         provided that the Foreign Risk Coverage Condition continues to exist at
         the time of such payment.

                  (iv) Payment of Related Costs. El Paso shall pay and assume
         liability for, and indemnify the Class A Shareholder against, all
         reasonable fees, costs and expenses attributable to or arising out of
         any determination of Foreign Risk Loss, including the portion of all
         reasonable fees and expenses of each FRCA Appraiser engaged in
         accordance with the FRCA Appraisal Procedures attributable to such
         determination of Foreign Risk Loss.

                  (v) Sale of Certain Assets to El Paso. Without limiting the
         obligations of El Paso under Section 6.1(c)(iii), at any time following
         a FRCA Appraisal with respect to a FRCA Asset for which a FRCA Asset
         Sale referred to in clause (b) or (c) of the definition thereof has
         occurred, El Paso (or its designee) will have the option, exercisable
         by notice from El Paso to Investor, to purchase such FRCA Asset for a
         consideration equal to (A) in the case of a FRCA Asset Sale referred to
         in such clause (b), one dollar and (B) in the case of a FRCA Asset Sale
         referred to in such clause (c), the Mark-to-Market Value of such FRCA
         Asset, and the other Parties agree to execute and deliver such further
         agreements, instruments or other documents, and take such further
         actions (all at El Paso's expense), as may be necessary or reasonably
         requested by El Paso to consummate the transfer of such FRCA Asset to
         El Paso or such designee.

         (d) ERISA Indemnification. El Paso agrees (except as provided below) to
indemnify, protect, defend and hold harmless Investor against any and all
actions, causes of action, suits, losses, liabilities, damages and expenses,
including reasonable attorneys' fees directly or indirectly resulting from or
attributable to (i) Liens for pension or social security obligations that are
not yet delinquent or are being contested in good faith and by appropriate
proceedings for which adequate reserves (in the good faith judgment of the
management of such Person) have been established, (ii) Liens for pension or
social security obligations that have been realized upon (a Lien described in
clauses (i) or (ii) above is referred to as an "ERISA Lien") and (iii) ERISA
liabilities of Topaz, Emerald, Citrine, Garnet, Diamond, Diamond Holdings,
Amethyst, Aquamarine or Peridot arising by or through any action or inaction of
El Paso or any of its Affiliates.

         Any amount payable pursuant to this Section 6.1(d) shall be payable to
Diamond within 15 Business Days after the date that (i) an ERISA Lien has been
realized upon, (ii) the asset encumbered by an ERISA Lien has been sold and such
sale was not free and clear of such

                                       34
<PAGE>

ERISA Lien or (iii) Investor paid any amount arising out of an ERISA liability
described in clause (iii) above, as applicable. The amount payable pursuant to
this Section 6.1(d) (in any case, a "Permitted Lien Loss") shall be (a) in the
case of clause (i) above, the difference between what the asset upon which the
ERISA Lien has been realized would have been worth prior to the realization of
such ERISA Lien and the residual value, if any, of such asset after the
realization of such ERISA Lien, (b) in the case of clause (ii) above, the
diminution in value of such asset as a result of such ERISA Lien and (c) in the
case of clause (iii) above, the amount paid by Investor as a result of any ERISA
liability described in clause (iii) above.

         (e) Limitations on Indemnification Obligations. The indemnification and
other obligations of El Paso provided in this Section 6.1 shall be subject to
the following limitations:

                  (i) Limitation by Law. Such indemnification or other
         obligations of El Paso shall be enforced only to the maximum extent
         permitted by law.

                  (ii) No Duplication. Indemnified amounts under this Section
         6.1 shall be without duplication of any amounts actually paid to
         Indemnified Persons under (A) indemnification, reimbursement or other
         provisions of any Transaction Document or (B) with respect to any
         Indemnified Person other than the Class A Shareholder or the Equity
         Investors (or any successor or permitted assign of the Class A
         Shareholder or the Equity Investors or any director, officer or
         employee of the Class A Shareholder, the Equity Investors or any such
         successor or permitted assign), any insurance policy or other relevant
         Contractual Obligation.

Except as expressly set forth in Section 6.1(b), Section 6.1(c) or Section
6.1(d), in no event shall El Paso have any indemnification obligation for, and
in no event shall El Paso be deemed a guarantor of, or otherwise be responsible
for, any Covered Losses, Foreign Risk Loss, Permitted Lien Loss or investment
losses incurred by the Class A Shareholder or any Equity Investor or the failure
of the Class A Shareholder to receive any yield or other return on, or return of
the Equity Component of, or any other amount in respect of, the Class A Shares
and the indemnification obligations of El Paso hereunder shall in no event
constitute a guaranty of payment with respect to the Class A Shares. In no event
shall El Paso have indemnification obligations (other than the indemnification
obligations arising pursuant to Section 6.1(a)) to the Class A Shareholder, any
Equity Investor, any director of Investor or any director of Citrine (after the
acceleration of the Emerald Loan) after (a) the Note Component has been reduced
to zero and all accrued and unpaid interest on the Notes has been paid in full
and (b) the Class A Shareholder has received payments (excluding indemnity and
expense reimbursement payments (other than payments received under Section
6.1(b), 6.1(c) or 6.1(d)) and, in the case of clause (1) below, any payments of
Shareholder Yield or Default Yield already received) that, in the aggregate, are
equal to (1) prior to the Extension Period Commencement Date, the Capital Price
or (b) on and after the Extension Period Commencement Date, the Target IRR
Amount.

         (f) Insured Items. In the case of any Indemnified Expenses, Covered
Losses, Foreign Risk Loss or Permitted Lien Loss covered by a policy of
insurance maintained by El Paso or any of its Affiliates, or by Topaz, Emerald,
Citrine, Garnet, Diamond, Diamond Holdings, Amethyst, Aquamarine, Peridot, any
Subsidiary of Amethyst, any Amethyst Minority Owned QEC, any Subsidiary of
Aquamarine or any Aquamarine Minority Owned QEC, or by any other Person,

                                       35
<PAGE>

each Indemnified Person agrees to provide reasonable cooperation to the insurers
in the exercise of their rights to investigate, defend, settle or compromise any
claim, action, suit or other circumstance giving rise to any Expense Payment,
Indemnified Expenses, Covered Losses, Foreign Risk Loss or Permitted Lien Loss
as may be required for El Paso or any of its Affiliates, or by Topaz, Emerald,
Citrine, Garnet, Diamond, Diamond Holdings, Amethyst, Aquamarine, Peridot, any
Subsidiary of Amethyst, any Amethyst Minority Owned QEC, any Subsidiary of
Aquamarine or any Aquamarine Minority Owned QEC, or any such other Person, to
retain the benefits of, and effect recovery under, such insurance with respect
to such item.

         (g) Claims Procedure. (i) An Indemnified Person shall, after obtaining
actual knowledge thereof, promptly notify El Paso in writing of any claim,
action, suit or other legal or regulatory proceeding (collectively, "Legal
Proceedings") or other event or circumstance giving rise to an Indemnified
Expense, Covered Loss or Permitted Lien Loss as to which indemnification will be
sought pursuant to this Agreement (the foregoing, collectively, "Indemnified
Events"); provided that the failure to give such notice shall not release El
Paso from any of its obligations under this Section 6.1, except (but only if El
Paso shall not have actual knowledge of such Indemnified Event) to the extent
that failure to give notice of any such Indemnified Event shall prejudice El
Paso's ability to defend or contest any Indemnified Event or Indemnified Expense
(or results in El Paso's forfeiture of substantive rights or defenses) or
recover proceeds under any insurance policies maintained by El Paso or any of
its Affiliates, or by Topaz, Emerald, Citrine, Garnet, Diamond, Diamond
Holdings, Amethyst, Aquamarine, Peridot, any Subsidiary of Amethyst, any
Amethyst Minority Owned QEC, any Subsidiary of Aquamarine or any Aquamarine
Minority Owned QEC, or by any other Person. El Paso shall, after a Responsible
Officer of El Paso obtains actual knowledge thereof, promptly notify each
Indemnified Person of any Indemnified Event affecting such Indemnified Person.
Each Indemnified Person agrees to provide El Paso with a copy of all relevant
documents and details, including all relevant papers served, claims made and
invoices received, in each case, as are reasonably requested by El Paso, to the
extent such information is available to such Indemnified Person and such
Indemnified Person can do so in a commercially reasonable manner. Subject to the
provisions of the following paragraph, El Paso shall at its sole option, and at
its sole cost and expense, be entitled to participate in, or to control and to
assume full responsibility for, the defense of such Indemnified Event with
Jones, Day, Reavis & Pogue or Fried, Frank, Harris, Shriver & Jacobson, or with
other counsel reasonably satisfactory to such Indemnified Person, and shall
provide the Indemnified Person(s) who are the subject of such Indemnified Event
with all information with respect to such Indemnified Event as such Indemnified
Person(s) shall reasonably request to the extent such disclosure shall not (A)
result in the waiver of any attorney-client privilege between El Paso and its
counsel or otherwise result in the loss of any attorney work product or other
privilege preventing disclosure of confidential material, (B) violate any
applicable provision relating to information that is required to be kept
confidential under any Contractual Obligation entered into by El Paso, EPED
Holding, EPED B, any Gemstone Party or any Subsidiary of any Gemstone Party with
any third Person in good faith in the ordinary course of business and in any
context that is not unreasonable in light of the contemplated transaction, (C)
violate any Applicable Law or (D) relate to information that El Paso, EPED
Holding or EPED B reasonably believes to be in the nature of trade secrets or
proprietary information.

                  (ii) Notwithstanding any of the foregoing to the contrary, El
         Paso shall not be entitled to control and assume responsibility for the
         defense of any Indemnified Event if

                                       36
<PAGE>

         (A) such Indemnified Person shall have reasonably concluded in good
         faith that there exists an actual or potential conflict of interest
         between such Indemnified Person and El Paso such that it is advisable
         for such Indemnified Person to retain control of all or any portion of
         such Indemnified Event (except that El Paso shall be entitled to
         control and assume responsibility for the defense of that portion of
         the Indemnified Event as to which such conflict of interest does not
         apply) or (B) such Indemnified Event involves the possibility of
         criminal sanctions against or criminal liability of such Indemnified
         Person. In the circumstances described in clauses (A) and (B) above,
         the Indemnified Person shall be entitled to control and assume
         responsibility for the defense of that aspect of such Indemnified Event
         covered by clauses (A) and (B) above at the expense of El Paso,
         provided that such defense is conducted by one counsel (in addition to
         any local counsel) acceptable to El Paso, such acceptance not to be
         unreasonably withheld or delayed. Each Indemnified Person, by its
         acceptance of any indemnification rights hereunder, agrees that El Paso
         shall only be responsible for the expenses of one counsel to be
         retained by all Indemnified Persons with respect to any Indemnified
         Event for which a claim for indemnification will be sought under this
         Section 6.1 in a particular jurisdiction, unless counsel to any
         Indemnified Person reasonably determines that there are actual or
         potential conflicts of interest between such Indemnified Person and
         other Indemnified Persons or that there may be one or more different or
         additional defenses, claims, counterclaims, or causes of action
         available to such Indemnified Person, in which case such Indemnified
         Person may retain separate counsel together with all other Indemnified
         Persons subject to the same conflict of interest or sharing such
         additional defenses, claims, counterclaims or causes of action at the
         expense of El Paso. In addition any Indemnified Person may participate
         in any Indemnified Event controlled by El Paso pursuant to this Section
         6.1, (1) at its own expense in respect of any such Indemnified Event as
         to which El Paso shall have acknowledged in writing its obligation to
         indemnify such Indemnified Person pursuant to this Section 6.1 for
         Indemnified Expenses (subject to the limitations and exclusions
         contained in this Agreement) and in a manner that is not materially
         prejudicial to the interests of El Paso and (2) at the expense of El
         Paso in respect of any such Indemnified Event as to which El Paso shall
         not have so acknowledged its obligation in respect of Indemnified
         Expenses to such Indemnified Person pursuant to this Section 6.1, or
         for so long as El Paso fails to assume responsibility for the defense
         of such Indemnified Event. El Paso may in any event participate in all
         Indemnified Events at its own cost. Nothing contained in this Section
         6.1(g) shall be deemed to require an Indemnified Person to contest any
         Indemnified Event or to assume responsibility for or control of any
         judicial proceeding with respect thereto.

                  (iii) Without the prior written consent of such Indemnified
         Person, El Paso shall not settle or compromise, or consent to the entry
         of any judgment in, any pending or threatened Indemnified Event, unless
         such settlement, compromise or consent or related judgment (a) includes
         an unconditional release of such Indemnified Person from all liability
         for Indemnified Expenses under the underlying claim in the Legal
         Proceeding that is the basis of such Indemnified Event and (b) does not
         include a statement as to or an admission of fault, culpability or a
         failure to act by or on behalf of such Indemnified Person. No
         Indemnified Person shall settle or compromise, or consent to the entry
         of any judgment, decree or order in, any pending or threatened
         Indemnified Event in respect of

                                       37
<PAGE>

         which any payment or claim for indemnification would or will result or
         be made by such Indemnified Person hereunder or under the other
         Transaction Documents without the prior written consent of El Paso,
         such consent not to be unreasonably withheld or delayed; provided that
         an Indemnified Person may take any of the foregoing actions if the
         failure to do so would subject such Indemnified Person to criminal
         liability, damage to its professional reputation or if El Paso has
         unreasonably withheld or delayed its consent to the Indemnified Person
         taking such actions.

         (h) Subrogation. If an Indemnified Expense, Covered Loss, Foreign Risk
Loss or Permitted Lien Loss indemnified by El Paso under this Section 6.1 other
than with respect to Taxes is paid in full by El Paso or an insurer under a
policy of insurance maintained by El Paso or any of its Affiliates or by Topaz,
Emerald, Citrine, Garnet, Diamond, Diamond Holdings, Amethyst, Aquamarine,
Peridot, any Subsidiary of Amethyst, any Amethyst Minority Owned QEC, any
Subsidiary of Aquamarine or any Aquamarine Minority Owned QEC, or by any other
Person, El Paso and/or such insured Person and/or such insurer, as the case may
be, shall be subrogated to the extent of such payment to the rights and remedies
of the Indemnified Person (other than (i) under insurance policies maintained by
such Indemnified Person other than the Class A Shareholder or the Equity
Investors (or any successor or permitted assign of the Class A Shareholder or
the Equity Investors or any director, officer or employee of the Class A
Shareholder, the Equity Investors or any such successor or permitted assign) or
(ii) against any of Investor, Topaz, Emerald, Citrine, Garnet, Diamond, Diamond
Holdings, Amethyst, Aquamarine, Peridot, the holders of the Class A Shares or
the Equity Investors) on whose behalf such Indemnified Expense, Covered Loss,
Foreign Risk Loss or Permitted Lien Loss was paid with respect to, where
applicable, the Indemnified Event giving rise thereto. So long as no event
referred to in Section 6.1(g)(ii)(A) shall have occurred and be continuing, if
an Indemnified Person receives any refund, in whole or in part, with respect to
any Indemnified Expense, Covered Loss, Foreign Risk Loss or Permitted Lien Loss
paid by El Paso hereunder, it shall promptly pay over the amount refunded (but
not in excess of the amount El Paso, any such other insured Person or any of
their respective insurers has paid) to El Paso or such other insured person, as
their interests may appear.

         (i) Affiliated Group. For purposes of Section 6.1(j), the term
"Indemnified Person" when used in respect of any Equity Investor (or a member,
partner or beneficiary of such Equity Investor that is a pass-through entity for
Tax purposes), shall include any combined, consolidated or affiliated group and
each member thereof of which such Equity Investor (or member, partner or
beneficiary of such Equity Investor that is a pass-through entity for Tax
purposes) is or shall become a member if combined or consolidated returns are or
shall be filed for such affiliated group for Tax purposes.

         (j) Calculation of Payments in Respect of Taxes. Any indemnity that El
Paso shall be required to make to or for the account of any Indemnified Person
under this Section 6.1 shall include an additional amount necessary to hold such
Indemnified Person harmless on an After-Tax Basis from any Taxes required to be
paid or accrued by such Indemnified Person as a result of such payment, and the
exclusion of the Excluded Items shall be disregarded in determining such
additional amount.

                                       38
<PAGE>

         (k) Payment in Respect of Taxes. El Paso shall pay any Tax for which it
is liable pursuant to this Section 6.1 directly to the appropriate taxing
authority on a timely basis sufficient to avoid the imposition of interest and
penalties (or upon demand of an Indemnified Person to such Indemnified Person
within 30 Business Days of a written demand, but in no event prior to the date
which is more than 5 days prior to the date such Tax is due (including all
extensions)) or, in the case of Taxes which are being contested pursuant to a
contest permitted pursuant to Section 6.1(g), within two Business Days after the
day such contest is finally resolved. Any such demand shall specify in
reasonable detail the calculation of the payment and the facts upon which the
right to payment is based. Each Indemnified Person shall promptly forward to El
Paso any notice, bill or advice received by it from the relevant taxing
authority concerning any Tax which El Paso may be required to indemnify against
hereunder but the failure to give such notice shall not diminish El Paso's
obligation hereunder except to the extent the right of El Paso to contest (or
cause a contest of) such claim in a court of competent jurisdiction is thereby
precluded. El Paso shall furnish the relevant Indemnified Person with the
original or a certified copy of a receipt (if any is available to El Paso) for
El Paso's payment of any Tax that is subject to indemnification pursuant to this
Section 6.1, or such other evidence of payment of such Tax as is reasonably
requested by such Indemnified Person.

         (l) Tax Savings. (i) Upon receipt by any Indemnified Person of a refund
(the amount of any such refund to be determined, in the case of an Indemnified
Person in the sole judgment of such Indemnified Person exercised in good faith;
it being understood that nothing contained in this Section 6.1(l) shall require
any Indemnified Person to make available any of its tax returns or any other
information that it deems to be confidential or proprietary) of all or part of
any Taxes that El Paso shall have paid for such Indemnified Person or for which
El Paso shall have reimbursed, advanced funds to or indemnified such Indemnified
Person, such Indemnified Person shall, but not before El Paso shall have made
all payments then due pursuant to this Section 6.1 and any other payments then
due to such Indemnified Person under any of the Transaction Documents and, in
any event, provided that no Event of Default or New Indenture Event of Default
shall have occurred and be continuing, pay or repay to El Paso an amount which,
after the addition of the amount of any further net deductions, credits, refunds
and other Tax savings actually realized by such Indemnified Person as a result
of the payment under this Section 6.1 (but only to the extent of the amounts
previously paid by El Paso with respect to such refunded Taxes in order to pay
them on an After-Tax Basis), the subtraction of any net Tax detriment realized
by such Indemnified Person as a result of the receipt or accrual of such refund
and the addition of any interest received or accrued by such Indemnified Person
on such refund, is equal to the amount of such refund and any interest received
or accrued by such Indemnified Person that is fairly attributable to such
refund. If it is later determined that the Indemnified Person was not entitled
to such refund, the portion of such refund that is repaid, recaptured or
disallowed will be treated as Taxes for which El Paso must indemnify the
Indemnified Person pursuant to the provisions of Section 6.1(a) but without
regard to the exclusion of Excluded Items.

                  (ii) If an Indemnified Person shall actually realize for any
         taxable period a reduction in a Tax (whether attributable to a credit,
         deduction, exclusion from income or otherwise) which would not have
         been realized but for any Tax, claim or other cost or expense with
         respect to which El Paso has reimbursed or indemnified such Indemnified
         Person on an After-Tax Basis pursuant to this Section 6.1, and such
         reduction in Tax was

                                       39
<PAGE>

         not taken into account in determining the amount payable by El Paso on
         account of such indemnification, such Indemnified Person shall pay to
         El Paso, so long as no Event of Default or New Indenture Event of
         Default shall have occurred and be continuing, within 30 days after
         such Indemnified Person shall have actually realized such Tax savings
         (but not before El Paso shall have made all payments then due pursuant
         to this Section 6.1 and any other payments then due to such Indemnified
         Person under any of the Transaction Documents), the amount of such
         savings, together with the amount of any Tax savings actually realized
         as a result of any payment pursuant to this sentence; provided that El
         Paso shall not be entitled to receive an amount in excess of the amount
         of such Indemnified Expenses, Taxes, claims, costs or expenses in
         respect of which the indemnification was paid by El Paso. Each
         Indemnified Person shall have sole control over the positions taken
         with respect to its tax returns and filings and such Indemnified Person
         shall determine in good faith the realization of any Tax benefit,
         saving, deduction or credit for purposes of calculations made under
         this Section 6.1. If it is later determined that the Indemnified Person
         was not entitled to such Tax savings or reduction in Tax, the portion
         of such Tax savings or reduction in Tax that is repaid, recaptured or
         disallowed will be treated as Taxes for which El Paso must indemnify
         the Indemnified Person pursuant to the provisions of Section 6.1(a) but
         without regard to the exclusion of Excluded Items.

         (m) Notice. In the event that El Paso is required to make any payments
pursuant to this Section 6.1 with respect to the Class A Shares, El Paso shall
provide each Equity Investor with written notice of the amount of such payment.

         (n) Other. To the extent any Indemnified Expenses are imposed on
Diamond, Diamond Holdings, any Diamond Project Company, Garnet or any Garnet
Project Company by any Governmental Authority directly or indirectly resulting
from or arising out of or alleged by a Person to result or arise out of (i) the
contribution or transfer of any Specified Diamond Assets to Diamond, Diamond
Holdings or any Diamond Project Company or (ii) the contribution or transfer of
any Specified Garnet Assets to Garnet or any Garnet Project Company, El Paso
shall indemnify, protect, defend and hold harmless each such Person on an
After-Tax Basis against such Indemnified Expenses.

         Section 6.2 No Multiple Indemnification Recoveries.

         Notwithstanding any provision in any Transaction Document to the
contrary, no Indemnified Person is entitled to multiple indemnification
recoveries on the same Indemnified Expense, Tax, claim or other costs or expense
under this Agreement or any other Transaction Document.

relevant jurisdiction), the remaining terms, provisions, covenants and
conditions of this Agreement, modified by the deletion of the unenforceable,
invalid or illegal portion (in any relevant jurisdiction), will continue in full

otherwise affect the enforceability, validity or legality of the remaining
terms. provisions, covenants or conditions of this Agreement so long as this
Agreement as so modified continues to express, without material change, the
original intentions of the Parties as to the subject matter hereof and the
deletion of such portion of this Agreement will not substantially impair the

         unable to agree upon the FRCA Appraised Value or FRCA Free Cash Flows,
         as required, of any FRCA Disputed Asset within the FRCA Agreement

         Business Days after the expiration of the FRCA Agreement Period, a

         Appraiser and the FRCA Second Appraiser are unable to agree on the FRCA
         Third Appraiser within the 10 Business Day period prescribed in the
         immediately preceding sentence, either El Paso or the Class A

         meet the FRCA Appraiser Requirements set forth in clause (a) above.

                  (d) on the second Business Day after the FRCA Third Appraiser

         Appraised Value or FRCA Free Cash Flows, as required, of each such FRCA

         required, of each such FRCA Disputed Asset, as so determined by the
         FRCA Third Appraiser, shall be the conclusive determination of FRCA
         Appraised Value or FRCA Free Cash Flows for purposes of the FRCA
         Appraisal Procedures.

Cash/Securities Fair Value of all cash and marketable securities of such FRCA
Asset not otherwise accounted for in the computation of Free Cash Flow or
terminal value minus (iv) to the extent applicable, all liabilities of such FRCA

Resolution to wind up Investor, Investor shall have the right, in its sole
discretion, to (i) apply for or consent to the appointment of, or the taking of

Shareholder in its sole discretion) of Investor or of all or a substantial part
of its assets, (ii) make a general assignment for the benefit of Investor's
creditors, (iii) file a petition seeking to take advantage of any other law

arrangement or winding-up, or composition or readjustment of debts or (iv) take
any action for the purpose of effecting any of the foregoing each with respect
to Investor upon 90 days' prior written notice to the Shareholders. The steps to
be accomplished by the liquidator are as follows:

         (a) As promptly as possible after commencement of the winding up, the
liquidator shall cause a proper account to be made of Investor's assets,

         transfer all or any portion of the Class A Shares and/or its rights
         under this Agreement in relation to such transferred Class A Shares;
         provided that, at the time of such transfer, the transferee is:

         (A)  a "Qualified Purchaser" within the meaning of section 2(a)(51) of
              the Investment Company Act, or an entity in which all of the
              equity owners are "Qualified Purchasers" within the meaning of
              section 2(a)(51) of the Investment Company Act; and

         (B)  an "accredited investor" within the meaning of rule 501(a)(1),
              (2), (3) or (7) under the Securities Act, or an entity in which

                  (ii)     10 Business Days after a Liquidation Notice takes
                           effect pursuant to section 12.10 of the Diamond LLC
                           Agreement, the Topaz LLC Agreement or the Garnet LLC

                           Remedy Notice; or

                  (iv)     10 days following delivery of a QMR Notice.

         (d) The Class B Shareholder shall pay, or cause the payment of, the
Share Purchase Option Price to the Class A Shareholder no later than 12:00 noon

provided that such date shall be no later than (x) 10 Business Days following
delivery of the Share Purchase Option Notice except as provided in the following

third party unrelated to El Paso (within the meaning of section 267(b) of the
Code or, otherwise as determined by the constructive ownership rules of section
318(a) of the Code, as modified by section 958(b) of the Code), and selected by
the Class B Shareholder in its sole discretion at a price equal to the Equity
Replacement Price, by providing a Share Purchase Option Notice to the Class A
Shareholder no earlier than five days prior to the end of any Fiscal Quarter and
no later than the tenth day of the next succeeding Fiscal Quarter. The Equity
Replacement Price shall be paid to the Class A Shareholder no later than 12:00
noon New York City time on the date specified in the Share Purchase Option
Notice, which date shall be no later than 10 Business Days following delivery of
the Share Purchase Option Notice. For purposes hereof, the "Equity Replacement
Price" is

an amount equal to (x) if the Equity Replacement Right is exercised prior to the
Extension Period Commencement Date, the Capital Price (determined as of the date
of purchase) as defined in Annex A and calculated using the formula specified in
clause (a) of such definition; or (y) in the event that the Equity Replacement
Right is exercised on or after the Extension Period Commencement Date, an amount

account the cash flows specified in the definition of Target IRR (without
duplication) and the purchase price paid for the Class A Shares.

the remaining terms, provisions, covenants and conditions of this Agreement so

change, the original intentions of the Parties as to the subject matter hereof
