         5.3 If the Companies require the replacement of the Management Company
pursuant to Section 5.2, the parties hereto (other than the Management Company)
shall negotiate in good faith to agree upon the terms of a new management
agreement to govern the rights and obligations of the Companies, on one hand,

compensation therefor to, the Successor Manager.

         5.4 Upon and subject to the appointment of the Successor Manager in
accordance with the replacement provisions of Section 5.2, this Agreement shall
terminate and the Successor Manager shall become vested with all the
administrative and management powers and duties of the Management Company. Upon

assign, transfer, deliver and pay over to the Successor Manager all moneys or
other property then held or subsequently received by the Management Company on

payment received pursuant to Sections 4.2, 7 or 10 in respect of the period
prior to termination.

         5.5 Notwithstanding any other provision of this Agreement (but without
limiting Section 6.4), and in addition to any other right that it may have, the
Management Company shall have the right to terminate this Agreement effective
immediately upon the Bankruptcy of Garnet.

         5.6 Without limiting the rights of the Companies to replace the

Management Company's rights to delegate its obligations to perform Services
hereunder pursuant to Section 3 and subject to Section 5.5, the Management
Company agrees that it will not voluntarily resign as manager for the provision

         Section 6. Standard of Care; Covenants of the Management Company

         6.1 The Management Company agrees to perform its duties hereunder in
good faith and in accordance with prudent standard industry practices for the
power generation industry (and in any event using a degree of skill and
attention no less than which El Paso exercises with respect to assets of such
character that it manages for itself) and in compliance with the applicable
provisions of the Garnet LLC Agreement, the Diamond LLC Agreement, the Diamond
Holding LLC Agreement, the Amethyst LLC Agreement, the Aquamarine LLC Agreement,
the Peridot Company Agreement and this Agreement.

         6.2 Notwithstanding any other provision of this Agreement, the

with, any express provision of the Garnet LLC Agreement, the Diamond LLC
Agreement, the Diamond Holdings LLC Agreement, the Amethyst LLC Agreement, the
Aquamarine LLC Agreement or the Peridot Company Agreement.

         6.3 The Management Company shall not cause any Company (or any business

<PAGE>

Permitted Assets) to enter into any transactions with El Paso or any Affiliate
of El Paso unless the terms of such transactions, taken as a whole, are fair and
reasonable at the time they are entered into and provide, in the aggregate, for
exchanges of fair consideration and reasonably equivalent value between or among
the parties thereto. Within 60 days after the end of each calendar quarter, the
Management Company shall provide to the Companies and Investor a written
certificate of an officer of the Management Company that any of such
transactions that occurred during such calendar quarter satisfied the standard
set forth in the immediately preceding sentence. This certification may be
delivered in conjunction with other quarterly officers' certificates required
under the Garnet LLC Agreement or the Diamond LLC Agreement. The requirements of
this Section 6.3 shall not apply to the execution of this Agreement but shall
apply to transactions with El Paso or its Affiliates occurring prior to the
Closing Date for assets contributed to or acquired by Amethyst or Aquamarine.

         6.4 Prior to the date that is a year and a day after the later to occur
of (i) the receipt by the Class A Shareholder of payments (excluding indemnity
and expense reimbursement payments (other than payments received under Section
6.1(b), 6.1(c) or 6.1(d) of the Participation Agreement) and, in the case of
clause (a) below, any payments of Shareholder Yield or Default Yield already
received) that, in the aggregate, are equal to (a) prior to the Extension Period
Commencement Date, the Capital Price or (b) on or after the Extension Period
Commencement Date, the Target IRR Amount and (ii) the receipt by the Class A
Shareholder, the Equity Investors, the directors of Investor and the directors
of Citrine (after the acceleration of the Emerald Loan) of all expense
reimbursement payments due and owed to such Persons on the date referred to in
clause (i) above pursuant to Section 5.5 of the Participation Agreement and
Section 5.05 of the Indenture, the Management Company will not institute
against, or join any other Person in instituting against any Company, Diamond
Holding, Amethyst, Aquamarine or Peridot, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings or similar proceedings under
the laws of the United States or any state of the United States, notwithstanding
any non-payment of fees, expenses, indemnities, reimbursements or other
obligations due and owing to the Management Company under this Agreement or
otherwise by a Company or any Operating Subsidiary of a Company.

         Section 7. Limitations on Liability; Indemnification.

         7.1 None of the Management Company, any Affiliate of the Management
Company to whom duties of the Management Company are subcontracted pursuant to
Section 3 or any agent, contractor, vendor, member, partner, manager, director,
officer, employee of the Management Company or any such Affiliate or any other
person who serves at the request of any of the foregoing in connection with this
Agreement (each severally, an "Exculpated Person") shall be liable, responsible
or accountable in damages or otherwise to the Companies or their respective
Subsidiaries for any losses, damages, liabilities, demands or expenses suffered
by the Companies or any of their respective Subsidiaries by reason of the
performance of the Services hereunder except to the extent arising out of (i)
the gross negligence or willful misconduct of such Exculpated Person or (ii) the
failure of the Management Company to perform any of its express obligations
under any of Sections 5.4, 5.6, 6.2, 6.3 and 6.4. Notwithstanding the foregoing,
each Exculpated Person may consult with external counsel and independent
accountants in respect of the Companies' and their respective Subsidiaries'
affairs and be fully protected and justified in any action or inaction which is
taken in accordance with the advice or



                                       6
<PAGE>

opinion of such counsel or accountants; provided that (a) such external counsel
and independent accountants shall have been selected with reasonable care and
(b) such Exculpated Person has no knowledge concerning the matter in question
that would cause such protection and justification to be unwarranted and is
otherwise acting in good faith. Notwithstanding any of the foregoing to the
contrary, the provisions of this Section 7.1 shall not be construed so as to
relieve (or attempt to relieve) the Exculpated Person of any liability
(including liability under federal securities laws which, under certain
circumstances, impose liability even on persons that act in good faith) to the
extent (but only to the extent) that such liability may not be waived, modified
or limited under applicable law, but shall be construed so as to effectuate the
provisions of this Section 7.1 to the fullest extent permitted by law.

In performing its duties, each Exculpated Person shall be entitled to rely on
information, opinions, reports or statements, including financial statements and
other financial data, in each case prepared or presented by: (i) one or more
third-party agents of the Management Company or any of its Affiliates; or (ii)
external counsel, independent accountants, consultants or other Persons (in each
case, selected with reasonable care) as to matters that such Exculpated Person
reasonably believes to be within such other Person's professional or expert
competence; provided that such Exculpated Person has no knowledge concerning the
matter in question that would cause such reliance to be unwarranted and is
otherwise acting in good faith.

The Companies agree that no Exculpated Person shall be liable to either Company
or any of their respective Subsidiaries for special, indirect, incidental,
exemplary, consequential or punitive damages, or loss of profits, revenue,
opportunity or goodwill, or increased costs, arising from the performance of the
Services hereunder, except where such damages or loss of profits are awarded to
a third party in a claim or action against either of the Companies with respect
to which either of the Companies has a specific obligation to indemnify such
third party.

         7.2 Garnet (but not Diamond) agrees for the benefit of each Exculpated
Person (as a party hereto or as a third party beneficiary hereof) to indemnify
and hold harmless each Exculpated Person from and against all claims, demands,
actions, investigations, losses, damages (including amounts paid in settlement),
liabilities or expenses (including reasonable attorneys' fees and expenses and
expenses of investigation) (collectively, "Losses") incurred by such Exculpated
Person arising out of the Services performed hereunder, except to the extent
that such Losses result from (i) the gross negligence or willful misconduct of
such Exculpated Person or (ii) the failure of the Management Company to perform
any of its express obligations under any of Sections 5.4, 5.6, 6.2, 6.3 and 6.4.

         7.3 Neither the limitation on liability nor any indemnity in favor of
any Exculpated Person pursuant to this Section 7 shall in any way limit the
indemnity of El Paso provided in Section 6.1 of the Participation Agreement or
the rights of the Companies under Section 5.

         Section 8. Survival of Terms. All agreements, representations,
warranties and indemnities contained in this Agreement and in any agreement,
document or certificate delivered pursuant hereto, or in connection herewith,
shall survive and continue in effect following the execution and delivery of
this Agreement and the Closing Date. The Companies agree that the limitations on
liability, waivers and disclaimers of liability, releases from liability and
indemnification and contribution provisions in this Agreement, and the
provisions of Section 4.2,



                                       7
<PAGE>

shall survive termination or expiration of this Agreement, and shall apply for
the benefit of the Exculpated Persons and the Management Company, as applicable.

         Section 9. Non-Waiver of Breach. Each of the Companies and the
Management Company may specifically waive any breach of this Agreement by the
other party, but no such waiver shall be deemed to have been given unless such
waiver is in writing, signed by the waiving party and specifically designates
the breach waived, nor shall any such waiver constitute a continuing waiver of
similar or other breaches.

         Section 10. Attorney Fees. If any party hereto, or third party
beneficiary hereof under Section 7, commences litigation or arbitration for the
judicial or other interpretation, enforcement, termination, cancellation or
rescission hereof, or for damages for the breach hereof (in the case of any
third party beneficiary hereof under Section 7 or 10, only in connection with
its rights under Section 7 or 10), the prevailing party in any such action,
trial, arbitration or appeal thereon shall be entitled to its reasonable
attorneys' fees and court, arbitration and other costs incurred, to be paid by
the losing party as fixed by the court or arbitrator in the same or a separate
suit, and whether or not such action is pursued to decision or judgment.

         Section 11. Force Majeure.

         11.1 Neither the Companies nor the Management Company nor any other
Exculpated Person shall be liable in damages to any other Person for any act,
omission or circumstance (each an "Event of Force Majeure") occasioned by or in
consequence of any acts of God, acts of the public enemy, wars, blockades,
insurrections, riots, epidemics, landslides, lightning, earthquakes, fires,
storms, floods, civil disturbances, explosions, sabotage, the binding order of
any court or governmental authority which has been resisted in good faith by all
reasonable legal means, federal, state or local laws, or other event or
circumstance not within the control of such party preventing such party from
performing its obligations hereunder, whether caused or occasioned by, or
happening on account of, the act or omission of one of the parties, not within
the control of the party claiming suspension and which by the exercise of due
diligence such party is unable to prevent or overcome.

         11.2 An Event of Force Majeure shall not relieve the Companies or the
Management Company of any liability any party may have under this Agreement in
the event of any party's concurring negligence or in the event of such party's
failure to use due diligence to remedy the situation and to remove the cause in
an adequate manner and with all reasonable dispatch, nor shall an Event of Force
Majeure relieve any party of liability unless such party shall give notice and
full particulars of the same in writing to the other party within 10 days of the
occurrence relied on. In no event, however, shall an Event of Force Majeure
relieve the Companies from the obligation of making payments due under this
Agreement at the time of such occurrence.

         Section 12. Amendments; Waivers. No amendment or waiver of any
provision of this Agreement, nor consent to any departure by any party hereto
therefrom, shall in any event be effective unless the same shall be in writing
and signed by each other party hereto affected thereby, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. No failure or delay on the part of any party hereto in
the exercise of any power or right hereunder shall operate as a waiver thereof.
No single or partial



                                       8
<PAGE>

exercise of any right or power hereunder shall operate as a waiver of such right
or of any other right or power. The waiver by any party hereto of a breach of
any provision of this Agreement shall not operate or be construed as a waiver of
any other or subsequent breach hereunder. All rights and remedies existing under
this Agreement are cumulative with, and not exclusive of, any rights or remedies
otherwise available.

         Section 13. Notices. All notices required or permitted under this
Agreement shall be in writing and shall be delivered to the parties hereto in
such manner and to such places as are specified in, and shall be deemed given or
effective as provided in, Section 7.2 of the Participation Agreement or may
otherwise be specified in accordance therewith.

         Section 14. Counterparts; Facsimile Signatures. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed signature page of this Agreement by facsimile
transmission shall be effective as delivery of a manually executed counterpart
hereof, and the party delivering such signature page by facsimile shall promptly
thereafter deliver to each other party hereto an original, duly executed
counterpart of such signature page.

         Section 15. Severability. If any term, provision, covenant or condition
of this Agreement, or the application thereof to any party hereto or any
circumstance, is held to be unenforceable, invalid or illegal (in whole or in
part) for any reason (in any 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 force and effect, and such unenforceability, invalidity or
illegality will not otherwise affect the enforceability, validity or legality of
the remaining terms, provisions, covenants and conditions of this Agreement so
long as this Agreement as so modified continues to express, without material
change, the original intentions of the parties hereto as to the subject matter
hereof and the deletion of such portion of this Agreement will not substantially
impair the respective expectations or reciprocal obligations of the parties
hereto or the practical realization of the benefits that would otherwise be
conferred upon the parties hereto. If any provision hereof is held to be
unenforceable, invalid or illegal as stated above, the parties hereto will
endeavor in good faith negotiations to replace such provision with a valid
provision, the economic effect of which comes as close as possible to that of
the prohibited or unenforceable provision.

         Section 16. Entire Agreement; Binding Effect and Transfers. This
Agreement, including the documents and instruments referred to herein,
constitutes the entire agreement and supersedes all other prior agreements and
undertakings, both written and oral, among the parties hereto, or any of them,
with respect to the subject matter hereof. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns and transferees. Without limiting the rights of the
Management Company under Sections 3 and 5, neither this Agreement nor any
interest or obligation in or under this Agreement may be transferred (whether by
way of security or otherwise) by any party without the prior written consent of
each other party (which consent shall not be unreasonably withheld) as expressly
contemplated hereby. Any purported transfer that is not in compliance with this
Section 16 will be void.
