security interest granted under this Section 2.01 attach to any lease, license,
contract, property rights, agreement or Government Approval to which any Obligor
is a party or any other part of the Collateral (or to any of its rights or
interests thereunder) if the grant of such security interest would constitute or
result in either (i) the abandonment, voiding, invalidation or unenforceability
of any right, title or interest of any Obligor therein or (ii) in a breach or
termination pursuant to the terms of, or a default under, any such lease,
license, contract, property rights, agreement or Government Approval (other

Sections 9-406, 9-407, 9-408 or 9-409 of the Uniform Commercial Code).

                                       8

Notwithstanding the foregoing, Collateral shall not include all Capital Stock of

extent that Obligor is permitted under Section 3.8 of the Depositary Agreement
to receive Restricted Payments, upon receipt by Obligor of such disbursements
made pursuant to Section 3.8 of the Depositary Agreement, such cash or other
property distributed to Obligor shall automatically be released, without any
further action by the Collateral Agent, from any security interest that may have
been created in such cash or other property pursuant to the foregoing grant
clause.

         Section 2.02. Obligations Unconditional. The obligations of Obligor in
this Agreement shall be continuing, irrevocable, primary, absolute and
unconditional irrespective of the value, genuineness, validity, regularity or
enforceability of any Financing Document or any other agreement or instrument
referred to therein, or any substitution, release or exchange of any guarantee
of or security for any of the Secured Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever
that might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor, it being the intent of this Section 2.02 that the
obligations of Obligor hereunder shall be absolute and unconditional under any
and all circumstances. Without limiting the generality of the foregoing, it is
agreed that the occurrence of any one or more of the following shall not alter
or impair the liability of Obligor hereunder, which shall remain absolute and
unconditional as described above without regard to and not be released,
discharged or in any way affected (whether in full or in part) by:

                  (a) at any time or from time to time, without notice to
         Obligor, the time for any performance of or compliance with any of the
         Secured Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (b) any Financing Document shall be amended or modified or
         there shall be a departure from, or waiver of, any of the terms of any
         Financing Document;

                  (c) the maturity of any of the Secured Obligations shall be
         accelerated, or any of the Secured Obligations shall be modified,
         supplemented or amended in any respect, or any right under any
         Financing Document or any other agreement or instrument referred to
         therein shall be waived or any guarantee of any of the Secured
         Obligations or any security therefore shall be released or exchanged in
         whole or in part or otherwise dealt with;

                  (d) any lien granted to, or in favor of, the Collateral Agent
         as security for any of the Secured Obligations shall fail to be
         perfected; or

                  (e) any proceeding, voluntary or involuntary, involving the
         bankruptcy, insolvency, receivership, reorganization, liquidation or
         arrangement of Obligor or the Note Issuer or by any defense which
         Obligor or the Note Issuer may have by reason of the order, decree or
         decision of any court or administrative body resulting from any such
         proceeding. Obligor acknowledges and agrees that the Secured
         Obligations include interest on the Secured Obligations at the
         applicable rate therefore under the Financing Documents which accrues
         after the commencement of any such proceeding (or, if interest on any
         portion of the Secured Obligations ceases to accrue by operation of law
         by reason of the commencement of said proceeding, such Secured

                                       9

         Obligations includes the interest which would have accrued on such
         portion of the Secured Obligations if said proceedings had not been
         commenced), since it is the intention of the parties that the amount of
         the Secured Obligations secured pursuant to this Agreement should be
         determined without regard to any rule of law or order which may relieve
         Obligor or the Note Issuer of any portion of the Secured Obligations.
         Obligor will permit any trustee in bankruptcy, receiver, debtor in
         possession, assignee for the benefit of creditors or similar person to
         pay the Collateral Agent, or allow the claim of the Collateral Agent in
         respect of, interest which would have accrued after the date on which
         such proceeding is commenced. Notwithstanding the above, so long as any
         Secured Obligation shall remain outstanding, Obligor shall not, without
         the prior written consent of the Collateral Agent, commence or join
         with any other person in commencing any bankruptcy, reorganization or
         insolvency proceedings of or against the Note Issuer.

         Section 2.03. Waiver.

                  (a) Obligor hereby expressly waives promptness, diligence,
         presentment, demand for payment or performance and protest; filing of
         claims with any court; any proceeding to enforce any provision of the
         Financing Documents; notice of acceptance of and reliance on this
         Agreement by the Secured Parties, notice of the creation of any Secured
         Obligations of the Note Issuer, and (except with respect to any notice
         required by the Transaction Documents) any other notice whatsoever; any
         requirement that the Collateral Agent exhausts any right, power or
         remedy or proceed or take any other action against Obligor or the Note
         Issuer under any Financing Document to which it is a party or any lien
         or encumbrance on, or any claim of payment against, any property of
         Obligor or the Note Issuer or any other agreement or instrument
         referred to therein, or any other Person under any guarantee of, or
         lien securing, or claim for payment of, any of the Secured Obligations;
         any right to require a proceeding by the Collateral Agent first against
         the Note Issuer whether to marshal any assets or to exhaust any right
         or take any action against the Note Issuer or any other Person or any
         collateral or otherwise, any diligence in collection or protection for
         realization upon any Secured Obligation; any obligation hereunder or
         any collateral security for any of the foregoing; any right of protest,
         presentment, notice or demand whatsoever, and any claims of waiver,
         release, surrender, alteration or compromise and all defenses,
         set-off's counterclaims, recoupments, reductions, limitations,
         impairments or terminations, whether arising hereunder or otherwise.
         Obligor further waives (i) any requirement that any other Person be
         joined as a party to any proceeding for the enforcement by the
         Collateral Agent of any Secured Obligation and (ii) the filing of
         claims by the Collateral Agent in the event of the receivership or
         bankruptcy of the Note Issuer. The Collateral Agent shall have the
         right to bring suit directly against Obligor with respect to the
         obligations owed to the Collateral Agent hereunder either prior to or
         concurrently with any lawsuit against, or without bringing any suit
         against Obligor, the Note Issuer or any other Person.

                  (b) The enforceability and effectiveness of this Agreement and
         the liability of Obligor, and the rights, remedies, powers and
         privileges of the Collateral Agent, under this Agreement shall not be
         affected, limited, reduced, discharged or

                                       10

         terminated, and Obligor hereby expressly waives to the fullest extent
         permitted by law any defense now or in the future arising, by reason
         of:

                           (i) the illegality, invalidity or unenforceability of
                  all or any part of the Secured Obligations, any Financing
                  Document or any agreement, security document, guarantee or
                  other instrument relating to all or any part of the Secured
                  Obligations;

                           (ii) any disability or other defense with respect to
                  all of any part of the Secured Obligations of Obligor,
                  including the effect of any statute of limitations that may
                  bar the enforcement of all or any part of the Secured
                  Obligations;

                           (iii) the illegality, invalidity or unenforceability
                  of any security or guarantee for all or any part of the
                  Secured Obligations or the lack of perfection or continuing
                  perfection or failure of the priority of any lien or
                  encumbrance on any collateral for all or any part of the
                  Secured Obligations;

                           (iv) the cessation, for any cause whatsoever, of the
                  liability of any Person that is a guarantor of all or any part
                  of the Secured Obligations (other than, subject to Section
                  2.05, by reason of the full payment and performance of all
                  Secured Obligations);

                           (v) except as required by Section 5.01 hereof, any
                  failure of the Collateral Agent to give notice of sale or
                  other disposition of any collateral (including any notice of
                  any judicial or non-judicial foreclosure or sale of any
                  interest in real property serving as collateral for all or any
                  part of the Secured Obligations) for all or any part of the
                  Secured Obligations to the Note Issuer, Obligor or any other
                  Person or any defect in, or any failure by the Note Issuer,
                  Obligor or any other Person to receive, any notice that may be
                  given in connection with any sale or disposition of any
                  collateral;

                           (vi) any failure of the Collateral Agent to comply
                  with applicable laws in connection with the sale or other
                  disposition of any collateral for all or any part of the
                  Secured Obligations;

                           (vii) any judicial or non-judicial foreclosure or
                  sale of, or other election of remedies with respect to, any
                  interest in real property or other Collateral serving as
                  security for all or any part of the Secured Obligations, even
                  though such foreclosure, sale or election of remedies may
                  impair the subrogation rights of either the Note Issuer or
                  Obligor or may preclude the Note Issuer or Obligor from
                  obtaining reimbursement, contribution, indemnification or
                  other recovery from the other Subsidiary Guarantors, the Note
                  Issuer or any other Person and even though the Note Issuer or
                  Obligor may not, as a result of such foreclosure, sale or
                  election of remedies, be liable for any deficiency;

                           (viii) any act or omission of the Collateral Agent or
                  any other Person (other than payment of the Secured
                  Obligations) that directly or indirectly

                                       11

                  results in or aids the discharge or release of Obligor or any
                  part of the Secured Obligations or any security or guarantee
                  (including any letter of credit) for all or any part of the
                  Secured Obligations by operation of law or otherwise;

                           (ix) any law which provides that the obligation of a
                  surety or Obligor must neither be larger in amount nor in
                  other respects more burdensome than that of the principal or
                  which reduces a surety's or Obligor's obligation in proportion
                  to the principal obligation;

                           (x) any counterclaim, set-off or other claim which
                  Obligor has or alleges to have with respect to all or any part
                  of the Secured Obligations;

                           (xi) any failure of the Collateral Agent to file or
                  enforce a claim in any bankruptcy or other proceeding with
                  respect to any Person;

                           (xii) the election by the Collateral Agent, in any
                  bankruptcy proceeding of any Person, of the application or
                  non-application of Section 1111(b)(2) of the United States
                  Bankruptcy Code;

                           (xiii) any extension of credit or the grant of any
                  lien or encumbrance under Section 364 of the United States
                  Bankruptcy Code;

                           (xiv) any use of cash collateral under Section 363 of
                  the United States Bankruptcy Code;

                           (xv) any agreement or stipulation with respect to the
                  provision of adequate protection in any bankruptcy proceeding
                  of any Person;

                           (xvi) the avoidance of any lien or encumbrance in
                  favor of the Collateral Agent for any reason;

                           (xvii) any bankruptcy, insolvency, reorganization,
                  arrangement, readjustment of debt, liquidation or dissolution
                  proceeding commenced by or against any Person, including any
                  discharge of, or bar or stay against collecting, all or any
                  part of the Secured Obligations (or any interest on all or any
                  part of the Secured Obligations) in or as a result of any such
                  proceeding; or

                           (xviii) any action taken by the Collateral Agent that
                  is authorized by this Section 2.03(b) or otherwise in this
                  Agreement or by any other provision of any Financing Document
                  or any omission to take any such action.

         Section 2.04. Reinstatement. The obligations of Obligor under this
Article II and the security interest in, and the lien on, the Collateral shall
be automatically reinstated if and to the extent that for any reason any payment
by or on behalf of Obligor in respect of the Secured Obligations is rescinded or
must be otherwise restored by any holder of any of the Secured Obligations or if
and to the extent that for any reason any payment by or on behalf of the Note
Issuer in respect of its obligations under the Indenture and the Senior Secured
Notes is rescinded or must be otherwise restored by any Noteholder, whether as a
result of any proceedings in

                                       12

bankruptcy or reorganization or otherwise. Obligor agrees that it will indemnify
the Collateral Agent on demand for all reasonable and reasonably documented
costs and expenses (including reasonable and reasonably documented fees of
counsel) incurred by the Collateral Agent in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

         Section 2.05. Subrogation. Obligor shall be subrogated to all rights of
the Collateral Agent and the Secured Parties in respect of any amounts paid by
Obligor pursuant to the terms of this Agreement; provided, however, that Obligor
hereby waives all rights of subrogation or contribution, whether arising by
contract or operation of law (including, without limitation, any such right
arising under any bankruptcy, insolvency or other similar law) or otherwise by
reason of any payment by it pursuant to the provisions of this Article II. If
any amount shall be paid to Obligor on account of such subrogation rights at any
time prior to the payment, discharge or performance in full of the Secured
Obligations, such amount shall be held in trust for the benefit of the
Collateral Agent (if applicable) and shall forthwith be paid to the Collateral
Agent to be credited and applied upon and against the Secured Obligations, to
the extent then matured, in accordance with the terms of the relevant Financing
Documents or, to the extent not then matured or existing, be held by the
Collateral Agent as collateral security for such Secured Obligations.

         Section 2.06. Remedies. Obligor agrees that, as between Obligor and the
Collateral Agent, any obligations of the Note Issuer to the Secured Parties
under any of the Financing Documents to which it is a party may be declared to
be forthwith due and payable notwithstanding any stay, injunction or other
prohibition (except any applicable prohibitions set forth in the Transaction
Documents) preventing such declaration (or such obligations from becoming
automatically due and payable) as against the Note Issuer and that, in the event
of such declaration (or such obligations being deemed to have become
automatically due and payable), such obligations shall forthwith be deemed to
have become due and payable for purposes of this Agreement. For the avoidance of
doubt, it is understood and agreed that any amount paid pursuant to the
immediately preceding sentence is intended to be applied to the payment or
prepayment (as the case may be) of the related obligations of the Note Issuer.
Each of the obligations of Obligor under this Agreement is separate and
independent of each other obligation of Obligor hereunder and separate and
independent of the Secured Obligations, and Obligor agrees that a separate
action or actions may be brought and prosecuted by the Collateral Agent against
Obligor to enforce this Agreement, irrespective of whether any action is brought
by the Collateral Agent against the Note Issuer under any relevant Financing
Document or whether the Note Issuer is joined in any such action or actions.

         Section 2.07. Continuing Obligation. The obligation provided in this
Article II is a continuing obligation and shall apply to all Secured Obligations
whenever arising.

         Section 2.08. [Intentionally Omitted].

         Section 2.09. Intellectual Property. For the purpose of enabling the
Collateral Agent to exercise its rights, remedies, powers and privileges under
Section 5.01 at that time or times as the Collateral Agent is lawfully entitled
to exercise those rights, remedies, powers and

                                       13

privileges, and for no other purpose, Obligor hereby grants to the Collateral
Agent, to the extent assignable or licensable, an irrevocable, non-exclusive
license (exercisable without payment of royalty or other compensation to
Obligor) to use, assign, license or sublicense any of the Intellectual Property
of Obligor, together with reasonable access to all media in which any of the
licensed items may be recorded or stored and to all computer programs used for
the compilation or printout of those items.

         Section 2.10. Perfection. Obligor authorizes the Collateral Agent to
file such financing statements and continuation statements in such offices as
are or shall be necessary or as the Collateral Agent may determine to be
appropriate to create, perfect and establish the priority of the liens granted
by this Agreement in any and all of the Collateral, to preserve the validity,
perfection or priority of the liens granted by this Agreement in any and all of
the Collateral or to enable the Collateral Agent to exercise its remedies,
rights, powers and privileges under this Agreement. Concurrently with the
execution and delivery of this Agreement, Obligor shall (i) deliver to the
Collateral Agent any and all certificates for all Certificated Securities,
including those identified in Annex 5, duly endorsed in blank; (ii) with respect
to any part of the Ownership Collateral that constitutes an uncertificated
security Obligor shall cause any issuer thereof to register the Collateral Agent
as the registered owner of such security; (iii) deliver to the Collateral Agent
any and all Instruments, endorsed or accompanied by such instruments of
assignment and transfer in such form and substance as the Collateral Agent may
reasonably request; (iv) cooperate with the Collateral Agent in obtaining, and
take such other actions as are necessary or that the Collateral Agent may
reasonably request in order for them to obtain Control with respect to all
Deposit Accounts, Investment Property, Electronic Chattel Paper and
Letter-of-Credit Rights included in the Collateral, including (to the extent
reasonably requested by the Collateral Agent) (A) in the case of any Deposit
Account for which the Collateral Agent is not the Bank at which that Deposit
Account is maintained, using commercially reasonable efforts to cause the Bank
to enter into an agreement in such form as the Collateral Agent may in its
reasonable discretion accept and (B) in the case of any Security Entitlement,
using commercially reasonable efforts to cause the relevant Securities
Intermediary to enter into an agreement in such form as the Collateral Agent may
in its reasonable discretion accept; (v) cause the Collateral Agent (to the
extent requested by the Collateral Agent) to be listed as the lienholder on all
certificates of title or ownership relating to Motor Vehicles in the name of
Obligor and deliver to the Collateral Agent originals of all such certificates
of title or ownership for the Motor Vehicles together with the odometer
statements for each respective Motor Vehicle; (vi) cause the Collateral Agent to
be listed as the lienholder on any certificate of title or ownership for any
other Equipment covered by a certificate of title or ownership; and (vii) take
all such other actions, and authenticate or sign and file or record such other
records or instruments, as are necessary or as the Collateral Agent may
reasonably request to perfect and establish the priority of the liens granted by
this Agreement in any and all of the Collateral or to enable the Collateral
Agent to exercise its remedies, rights, powers and privileges under this
Agreement, including, without limitation, causing any or all of the Collateral
to be transferred of record into the name of the Collateral Agent as such (and
the Collateral Agent agrees that if any Collateral is transferred into its name,
the Collateral Agent will thereafter promptly give to Obligor copies of any
notices and communications received by it with respect to the Collateral pledged
by Obligor hereunder).

         Section 2.11. Preservation and Protection of Security Interests.
Obligor shall:

                                       14

         Obligor of any Certificated Securities, Instruments, Deposit Accounts,
         other Investment Property, Electronic Chattel Paper, Letter-of Credit
         Rights, Motor Vehicles or other Equipment covered by a certificate of
         title or ownership promptly (x) take such action with respect to that
         Collateral as is specified for that type of Collateral in Section 2.10
         and (y) take all such other actions, and authenticate or sign and file
         or record such other records or instruments, as are necessary or as the
         Collateral Agent may reasonably request to create, perfect and
         establish the priority of the liens granted by this Agreement in any
         and all the Collateral, to preserve the validity, perfection or
         priority of the liens granted by this Agreement in any and all of the
         Collateral or to enable the Collateral Agent to exercise its remedies,
         rights, powers and privileges under this Agreement;

                  (b) upon Obligor's acquiring, or otherwise becoming entitled
         to the benefits of, any Copyright (or copyrightable material), Patent
         (or patentable invention), Trademark (or associated goodwill) or other
         Intellectual Property or upon or prior to Obligor's filing, either
         directly or through the Collateral Agent, any licensee or any other
         designee, of any application with any governmental authority for any
         Copyright, Patent, Trademark or other Intellectual Property, in each
         case after the date of this Agreement, execute and deliver such
         contracts, agreements and other instruments as the Collateral Agent may
         reasonably request to create, perfect and establish the priority of the
         liens granted by this Agreement in that and any related Intellectual
         Property; and

                  (c) whether with respect to Collateral as of the date of this
         Agreement or Collateral in which Obligor acquires rights in the future,
         authorize, give, authenticate, execute, deliver, file or record any and
         all financing statements, notices, contracts, agreements or other
         records or instruments, obtain any and all Governmental Approvals, and
         take all such other actions, as are necessary or as the Collateral
         Agent may reasonably request to create, perfect and establish the
         priority of the liens granted by this Agreement in any and all the
         Collateral, to preserve the validity, perfection or priority of the
         liens granted by this Agreement in any and all of the Collateral or to
         enable the Collateral Agent to exercise and enforce its remedies,
         rights, powers and privileges under this Agreement, including causing
         any or all of the Ownership Collateral to be transferred of record into
         the name of the Collateral Agent or its nominee (and the Collateral
         Agent agrees that if any Security is transferred into its name or the
         name of its nominee, the Collateral Agent shall thereafter promptly
         give to Obligor copies of any notices and communications received by it
         with respect to that Security); and

                  (d) furnish to the Collateral Agent from time to time
         statements and schedules further identifying and describing the
         Collateral pledged by hereunder and such other reports in connection
         with the Collateral pledged by Obligor hereunder as the Collateral
         Agent may reasonably request, all in reasonable detail.

         Section 2.12. Attorney-in-Fact.

                  (a) Subject to Obligor's rights under Sections 2.13 through
         2.16, Obligor hereby irrevocably constitutes and appoints the
         Collateral Agent and any officer or agent thereof, with full power of
         substitution, as its true and lawful attorney-in-fact

                                       15

         with full irrevocable power and authority in the place and stead of
         Obligor and in the name of Obligor or in its own name, for the purpose

         connection therewith, give such discharges or releases as the
         Collateral Agent may deem appropriate, (G) assign any Copyright, Patent
         or Trademark (along with the goodwill of the business to which any such
         Trademark pertains) throughout the world for such term or terms, on
         such conditions, and in such manner as the Collateral Agent shall in
         its sole discretion determine, including the execution and filing of
         any document necessary to effectuate or

                                       16

         record such assignment and (H) generally, sell, transfer, pledge and
         make any agreement with respect to or otherwise deal with any
         Collateral as fully and completely as though the Collateral Agent were
         the absolute owner thereof for all purposes, and do, at the Collateral
         Agent's option and Obligor's expense, at any time, or from time to
         time, all acts and things that the Collateral Agent reasonably deems
         necessary to protect, preserve or realize upon the Collateral and the
         Collateral Agent's and the other Secured Parties' security interests
         therein and to effect the intent of this Agreement, all as fully and
         effectively as Obligor might do.

                  (b) Without limiting the rights and powers of the Collateral
         Agent under Section 2.12(a), Obligor hereby appoints the Collateral
         Agent as its attorney-in-fact, effective the date of this Agreement and
         terminating upon the Discharge Date, for the purpose of, upon the
         occurrence and during the continuation of an Event of Default, (i)
         executing on behalf of Obligor title or ownership applications for
         filing with appropriate state agencies to enable Motor Vehicles now
         owned or in the future acquired by Obligor to be retitled and the
         Collateral Agent to be listed as lien holder as to those Motor
         Vehicles, (ii) filing such applications with such state agencies, and
         (iii) executing such other documents and instruments on behalf of, and
         taking such other action in the name of, Obligor as the Collateral
         Agent may deem necessary or advisable to accomplish the purposes of
         this Agreement (including the purpose of creating in favor of the
         Collateral Agent a perfected lien on the Motor Vehicles and exercising
         the rights, remedies, powers and privileges of the Collateral Agent
         under Section 5.01). This appointment as attorney-in-fact is
         irrevocable and coupled with an interest.

                  (c) Without limiting the rights and powers of the Collateral
         Agent under Section 2.12(a), Obligor hereby appoints the Collateral
         Agent as its attorney-in-fact, effective the date of this Agreement and
         terminating upon the Discharge Date, at the Collateral Agent's option,
         but without any obligation so to do, for the purpose of performing,
         executing, and filing all such contracts, agreements and other
         documents as are contemplated by Section 2.11(b). This appointment as
         attorney-in-fact is irrevocable and coupled with an interest.

                  (d) The expenses of the Collateral Agent incurred in
         connection with actions undertaken as provided in this Section 2.12,
         together with interest thereon at a rate per annum equal to the rate
         per annum at which interest would then be payable on past due Notes
         under the Indenture, from the date of payment by the Collateral Agent
         to the date reimbursed by Obligor, shall be payable by Obligor to the
         Collateral Agent on demand and shall constitute Secured Obligations and
         be secured by the Liens of the Collateral Documents.

                  (e) Obligor hereby ratifies all that said attorneys shall
         lawfully do or cause to be done by virtue hereof. All powers,
         authorizations and agencies contained in this Agreement are coupled
         with an interest and are irrevocable until this Agreement is terminated
         and the security interests created hereby are released.

         Section 2.13. Special Provisions Relating to Securities.

                                       17

                  (a) So long as no Event of Default has occurred and is
         continuing, Obligor shall have the right to exercise all voting,
         consensual and other powers of ownership pertaining to all Ownership
         Collateral for all purposes not inconsistent with the terms of any
         Transaction Document, provided that Obligor shall not vote the
         Ownership Collateral in any manner that is inconsistent with the terms
         of any Transaction Document; and the Collateral Agent shall, at
         Obligor's expense, execute and deliver to Obligor or cause to be
         executed and delivered to Obligor all such proxies, powers of attorney,
         dividend and other orders and other instruments, without recourse, as
         Obligor may reasonably request for the purpose of enabling Obligor to
         exercise the rights and powers that it is entitled to exercise pursuant
         to this Section 2.13(a).

                  (b) So long as no Event of Default has occurred and is
         continuing, Obligor shall be entitled to receive and retain any
         dividends on all Ownership Collateral paid in cash.

                  (c) If any Event of Default has occurred and is continuing,
         and whether or not the Collateral Agent exercises any available right
         to declare any Secured Obligation due and payable or seeks or pursues
         any other right, remedy, power or privilege available to it under
         applicable law, this Agreement or any other Transaction Document, all
         dividends and other distributions on all Ownership Collateral shall be
         paid directly to an account designated by the Collateral Agent and
         retained by it in such account as part of the Collateral, subject to
         the terms of the Transaction Documents, and, if the Collateral Agent so
         requests, Obligor shall execute and deliver to the Collateral Agent
         appropriate additional dividend, distribution and other orders and
         instruments to that end, provided that if the applicable Event of
         Default is cured, any such dividend or distribution paid to the
         Collateral Agent prior to that cure shall, upon request of Obligor
         (except to the extent applied to the Secured Obligations), be returned
         by the Collateral Agent to Obligor.

         Section 2.14. Instruments. So long as no Event of Default has occurred
and is continuing, Obligor may retain for collection in the ordinary course of
business any Instruments obtained by it, and the Collateral Agent will, promptly
upon the request, and at the expense of, Obligor, make appropriate arrangements
for making any Instruments pledged by Obligor available to Obligor for purposes
of presentation, collection or renewal. Any such arrangement shall be effected,
to the extent deemed appropriate by the Collateral Agent, against a trust
receipt or like document.

         Section 2.15. Use of Collateral. So long as no Event of Default has
occurred and is continuing, Obligor shall be entitled to use and possess the
Collateral, subject to the rights, remedies, powers and privileges of the
Collateral Agent under Articles II and V.

         Section 2.16. Rights and Obligations.

                  (a) No reference in this Agreement to proceeds or to the sale
         or other disposition of Collateral shall authorize Obligor to pledge,
         sell or otherwise dispose of any Collateral except to the extent
         otherwise expressly permitted by the terms of any

                                       18

         Transaction Document. The Collateral Agent shall not be required to
         take steps necessary to preserve any rights against prior parties to
         any part of the Collateral.

                  (b) Obligor shall remain liable to perform its duties and
         obligations under the contracts and agreements included in the
         Collateral in accordance with their respective terms to the same extent
         as if this Agreement had not been executed and delivered. The exercise
         by the Collateral Agent of any right, remedy, power or privilege in
         respect of this Agreement shall not release Obligor from any of its
         duties and obligations under those contracts and agreements. The
         Collateral Agent shall not have any duty, obligation or liability under
         those contracts and agreements or in respect to any Governmental
         Approval included in the Collateral by reason of this Agreement or any
         other Transaction Document, nor shall the Collateral Agent be obligated
         to perform any of the duties or obligations of Obligor under any such
         contract or agreement or any such Governmental Approval or to take any
         action to collect or enforce any claim (for payment) under any such
         contract or agreement or Governmental Approval.

                  (c) No lien granted by this Agreement in Obligor's right,
         title and interest in any contract, agreement or Governmental Approval
         shall be deemed to be a consent by the Collateral Agent to any such
         contract, agreement or Governmental Approval.

         Section 2.17. Release of Collateral. Upon the Discharge Date, or the
date of any sale or conveyance of a motor vehicle or any other portion of the
Collateral for which Obligor is entitled, pursuant to the terms and conditions
of the Indenture, to sell or otherwise convey free and clear of the Liens of the
Transaction Documents, and upon the request of, and at the expense of, Obligor,
the Collateral Agent will execute and deliver to Obligor such instruments as
Obligor reasonably requests to remove the notation of the Collateral Agent as
lienholder on any certificate of title for any Motor Vehicle or any other
certificate of title or other financing statement with respect to such
applicable portion of the Collateral; provided that in connection with such sale
or conveyance, any such instruments shall be delivered, and the release shall be
effective, only upon receipt by the Collateral Agent of a certificate from
Obligor stating that the Motor Vehicle or other such portion of the Collateral
the lien on which is to be released is to be sold or conveyed in accordance with
the terms and conditions of the Indenture.

         Section 2.18. Commercial Tort Claims. Obligor agrees that, if it shall
acquire any interest in any Commercial Tort Claim (whether from another Person
or because such Commercial Tort Claim shall have come into existence), (i)
Obligor shall, immediately upon such acquisition, deliver to the Collateral
Agent, in each case in form and substance satisfactory to the Collateral Agent,
a notice of the existence and nature of such Commercial Tort Claim and deliver a
supplement to Annex 4 containing a specific description of such Commercial Tort
Claim, certified by Obligor as true, correct and complete, (ii) the provisions
of Section 2.01 shall apply to such Commercial Tort Claim (and Obligor
authorizes the Collateral Agent to supplement such annex with a description of
such Commercial Tort Claim if Obligor fails to deliver the supplement described
in clause (i)), and (iii) Obligor shall execute and deliver to the Collateral
Agent, in each case in form and substance satisfactory to the Collateral Agent,
any certificate, agreement and other document, and take all other action, deemed
by the Collateral Agent to be reasonably necessary or appropriate for the
Collateral Agent to obtain, on behalf of

                                       19

the Secured Parties, a first-priority, perfected security interest in all such
Commercial Tort Claims. Any supplement to Annex 4 delivered pursuant to this
Section 2.18 shall become part of such Annex 4 for all purposes hereunder.

         Section 2.19. Termination. Upon the occurrence of the Discharge Date,
all liens granted hereunder shall be deemed terminated, and the Collateral Agent
shall forthwith cause to be assigned, transferred and delivered, against receipt
but without any recourse, warranty or representation whatsoever, any remaining
Collateral and money received in respect of the Collateral, to or on the order
of Obligor. The Collateral Agent shall also execute and deliver to Obligor, at
Obligor's expense, upon the occurrence of the Discharge Date such Uniform
Commercial Code termination statements and other documentation as shall be
reasonably requested by Obligor to effect the termination and release of the
liens created under this Agreement. The security interest created hereby and the
other liens created by the Transaction Documents shall also be released with
respect to any portion of the Collateral that is sold, transferred or otherwise
disposed of in compliance with the terms and conditions of the Transaction
Documents.

                                  ARTICLE III
                                 REPRESENTATIONS

         As of the date hereof Obligor represents and warrants to the Collateral
Agent as follows:

         Section 3.01. Organization; Validity.

                  (a) Annex 1 correctly sets forth Obligor's full and correct
         legal name, type of organization, jurisdiction of organization,
         organizational identification number (if applicable), chief executive
         office and mailing address as of the date of this Agreement.

                  (b) Obligor has not (i) changed its location (as defined in
         Section 9-307 of the Uniform Commercial Code), (ii) previously changed
         its name except as set forth on Annex 1 and (iii) previously become a
         "new debtor" (as defined in the Uniform Commercial Code) with respect
         to a currently effective security agreement entered into by another
         Person except as set forth on Annex 1.

         Section 3.02. Title. Obligor is the sole beneficial owner of the
Collateral in which it purports to grant a lien pursuant to this Agreement, and
the Collateral is free and clear of all liens (subject to any Permitted Liens)
and the lien granted by this Agreement has attached and constitutes a perfected
security interest in all of the Collateral prior to all other liens and
encumbrances.

         Section 3.03. Pledged Ownership Interests.

                  (a) The Pledged Ownership Interests identified in Annex 5 are
         duly authorized, validly existing, fully paid and non-assessable, and
         none of the Pledged Ownership Interests is subject to any contractual
         restriction, or any restriction under the organizational documents of
         any Subsidiary Guarantor, upon the transfer of such Pledged

                                       20

         Ownership Interests (except for any such restriction contained in any
         Transaction Document). Such Pledged Ownership Interests exist in a
         certificated form.

                  (b) The Pledged Ownership Interests identified in Annex 5
         constitute all of the issued and outstanding membership interests or
         other interests of any class or character in any Subsidiary Guarantor
         owned by Obligor (whether or not registered in the name of Obligor),
         and Annex 5 correctly identifies the issuer of such Pledged Ownership
         Interests and the respective number (and registered owners) of the
         interests identified in Annex 5.

                  (c) No Person other than Obligor is the registered owner of
         the Pledged Ownership Interests.

         Section 3.04. Intercompany Notes. The intercompany notes identified in
Annex 6 constitute all of the outstanding intercompany notes payable to Obligor.

         Section 3.05. Confirmation. Obligor hereby makes the representations
and warranties specified to be applicable to Obligor in Section 2 of the Note
Purchase Agreement, and each such representation and warranty is hereby
incorporated by reference in this Agreement, mutatis mutandis, as a direct
representation and warranty of Obligor with respect to itself.

                                   ARTICLE IV
                                    COVENANTS

         Until the Discharge Date, Obligor agrees that, from time to time upon
the written request of the Collateral Agent, Obligor will execute and deliver
such further documents and do such other acts and things as the Collateral Agent
may reasonably request in order fully to effect the purposes of this Agreement.
Obligor agrees to observe and perform during the period commencing on the date
hereof and ending on the Discharge Date each of the covenants specified to be
applicable to Obligor in Article IV of the Indenture, and each such covenant and
agreement is hereby incorporated by reference in this Agreement, mutatis
mutandis, as a direct obligation, covenant and agreement of Obligor with respect
to itself.

                                   ARTICLE V
                                    REMEDIES

         Section 5.01. Events of Default, Etc. Without limiting the rights,
powers and privileges of the Collateral Agent under Article II, if any Event of
Default shall have occurred and be continuing:

                  (a) The Collateral Agent in its discretion may require Obligor
         to, and Obligor shall, assemble the Collateral owned by it at such
         place or places, reasonably convenient to both the Collateral Agent and
         Obligor, designated in the Collateral Agent's request;

                  (b) The Collateral Agent in its discretion may make any
         reasonable compromise or settlement it deems desirable with respect to
         any of the Collateral and

                                       21

         may extend the time of payment, arrange for payment in installments, or
         otherwise modify the terms of, all or any part of the Collateral;

                  (c) The Collateral Agent in its discretion may, in its name or
         in the name of Obligor or otherwise, demand, sue for, collect or
         receive any money or property at any time payable or receivable on
         account of or in exchange for all or any part of the Collateral, but
         shall be under no obligation to do so;

                  (d) The Collateral Agent in its discretion may, upon ten (10)
         Business Days' prior written notice to Obligor of the time and place,
         with respect to all or any part of the Collateral which shall then be
         or shall thereafter come into the possession, custody or control of the
         Collateral Agent or any of its agents, sell, lease or otherwise dispose
         of all or any part of such Collateral, at such place or places as the
         Collateral Agent deems best, for cash, for credit or for future
         delivery (without thereby assuming any credit risk) and at public or
         private sale, without demand of performance or notice of intention to
         effect any such disposition or of time or place of any such sale
         (except such notice as is required above or by applicable statute and
         cannot be waived), and the Collateral Agent or any other Person may be
         the purchaser, lessee or recipient of any or all of the Collateral so
         disposed of at any public sale (or, to the extent permitted by law, at
         any private sale) and thereafter hold the same absolutely, free from
         any claim or right of whatsoever kind, including any right or equity of
         redemption (statutory or otherwise), of Obligor, any such demand,
         notice and right or equity being hereby expressly waived and released.
         The Collateral Agent may, without notice or publication, adjourn any
         public or private sale or cause the same to be adjourned from time to
         time by announcement at the time and place fixed for the sale, and such
         sale may be made at any time or place to which the sale may be so
         adjourned;

                  (e) The Collateral Agent shall have, and in its discretion may
         exercise, all of the rights, remedies, powers and privileges with
         respect to the Collateral of a secured party under the Uniform
         Commercial Code (whether or not the Uniform Commercial Code is in
         effect in the jurisdiction where such rights, remedies, powers and
         privileges are asserted) and such additional rights, remedies, powers
         and privileges to which a secured party is entitled under the laws in
         effect in any jurisdiction where any rights, remedies, powers and
         privileges in respect of this Agreement or the Collateral may be
         asserted, including the right, to the maximum extent permitted by law,
         to exercise all voting, consensual and other powers of ownership
         pertaining to the Collateral as if the Collateral Agent were the sole
         and absolute owner of the Collateral (and Obligor agrees to take all
         such action as may be appropriate to give effect to such right);

                  (f) The Collateral Agent in its discretion may, to the full
         extent provided by law, have a court having jurisdiction appoint a
         receiver, which receiver shall take charge and possession of and
         protect, preserve, replace and repair the Collateral or any part
         thereof, and manage and operate the same, and receive and collect all
         rents, income, receipts, royalties, revenues, issues and profits
         therefrom. Obligor irrevocably consents and shall be deemed to have
         hereby irrevocably consented to the appointment thereof, and upon such
         appointment, Obligor shall immediately deliver possession of such
         Collateral to the receiver. Obligor also irrevocably consents to the
         entry of an order

                                       22

         authorizing such receiver to invest upon interest any funds held or
         received by the receiver in connection with such receivership. The
         Collateral Agent shall be entitled to such appointment as a matter of
         right, if it shall so elect, without the giving of notice to any other
         party and without regard to the adequacy of the security of the
         Collateral; and

                  (g) The Collateral Agent in its discretion may enforce one or
         more remedies hereunder, successively or concurrently, and such action
         shall not operate to estop or prevent the Collateral Agent from
         pursuing any other or further remedy which it may have hereunder or by
         law, and any repossession or retaking or sale of the Collateral
         pursuant to the terms hereof shall not operate to release Obligor until
         full and final payment of any deficiency has been made. Obligor shall
         reimburse the Collateral Agent upon demand for, or the Collateral Agent
         may apply any proceeds of Collateral to, the costs and expenses
         (including reasonable attorneys' fees, transfer taxes and any other
         charges) incurred by the Collateral Agent in connection with any sale,
         disposition, repair, replacement, alteration, addition, improvement or
         retention of any Collateral hereunder.

The proceeds of, and other realization upon, the Collateral by virtue of the
exercise of remedies under this Section 5.01 shall be applied in accordance with
Section 5.04.

         Section 5.02. Deficiency. If the proceeds of, or other realization
upon, the Collateral by virtue of the exercise of remedies under Section 5.01
are insufficient to cover the costs and expenses of such exercise and the
payment in full of the Secured Obligations, Obligor shall remain liable for any
deficiency.

                      Private Sale.

                  (a) The Collateral Agent shall not incur any liability as a
         result of the sale, lease or other disposition of all or any part of
         the Collateral at any private sale pursuant to Section 5.01 conducted
         in a commercially reasonable manner. Obligor hereby waives any claims
         against the Collateral Agent arising by reason of the fact that the
         price at which the Collateral may have been sold at such a private sale
         was less than the price which might have been obtained at a public sale
         or was less than the aggregate amount of the Secured Obligations, even
         if the Collateral Agent accepts the first offer received and does not
         offer the Collateral to more than one offeree.

                  (b) Obligor recognizes that, by reason of certain prohibitions
         contained in the Securities Act of 1933 and applicable state securities
         laws, the Collateral Agent may be compelled, with respect to any sale
         of all or any part of the Collateral, to limit purchasers to those who
         will agree, among other things, to acquire the Collateral for their own
         account, for investment and not with a view to distribution or resale.
         Obligor acknowledges that any such private sales may be at prices and
         on terms less favorable to the Collateral Agent than those obtainable
         through a public sale without such restrictions, and, notwithstanding
         such circumstances, agree that any such private sale shall be deemed to
         have been made in a commercially reasonable manner and that the
         Collateral Agent shall have no obligation to engage in public sales and
         no obligation to delay the sale of any Collateral for the period of
         time necessary to permit the respective issuer of such Collateral to
         register it for public sale.

                                       23

         Section 5.03. Application of Proceeds. The Proceeds of, or other
realization upon, all or any part of the Collateral by virtue of the exercise of

                             AND SALE OF ELECTRICITY

          THIS AGREEMENT for the purchase and sale of electricity is entered
into as of the date of this execution by and between GEOTHERMAL DEVELOPMENT
ASSOCIATES, a Nevada corporation, ("Seller"), and SIERRA PACIFIC POWER COMPANY,
a Nevada corporation ("Purchaser"), upon the following terms and conditions:

          IT IS AGREED:

          (1)   Sale of Electricity. Seller shall sell and Purchaser shall
purchase all of the electricity generated and delivered to the Point of
Delivery, defined herein, by Seller at its facility for generation of electric
power ("the Plant") to be located on land leased from Purchaser which land is
more particularly described in Exhibit A, attached hereto and incorporated
herein by this reference. Said Plant shall have nameplate rating of 5MW
(net-maximum) and shall be fueled by geothermal energy.

          (2)   Performance Criteria. Seller shall comply with the following
performance criteria:

                (a)  Within 270 days of the execution of this Agreement, Seller
shall complete and bring to commercial fluid production, one geothermal well on
the land leased from Purchaser under that certain lease of even date
hereinwith, or land pooled or unitized therewith. For purposes of this
Agreement, the term "Commercial Fluid Production" shall mean the point at which
a geothermal well, alone or in combination with

other wells, is producing, or is capable of producing, a resource of sufficient
temperature and volume to supply twenty-five percent (25%) of the Plant's heat
requirements.

                (b)  Within three (3) calendar years of the execution of this
Agreement, Seller shall construct and bring to commercial power production, one
electrical generating plant with a maximum nameplate rating of 5 MW
(net-maximum). For the purposes of this Agreement, the term "commercial power
production" shall mean the point at which the first kilowatt hour is delivered
to the Point of Delivery.

          If Seller should fail to meet either of the performance criteria in
the time stated, this Agreement shall be null and void and the obligations of
both parties hereunder shall terminate automatically and without notice.
Seller's compliance with the performance criteria shall be subject to written
verification by Purchaser, which verification shall not be unreasonably
withheld. Time frames quoted above may be extended by Purchaser if circumstances
beyond Seller's control have impeded Seller's performance, provided Seller has
used due diligence in attempting to mitigate such circumstances and meet the
stated time limitation. Purchaser's extension of the time limit for one
performance criterion does not constitute a waiver of the other, or affect in
any way the Purchaser's right to its enforcement.

          (3)   Rate.

                (a)  For all power purchased from Seller's facility at the point
of Delivery, Purchaser shall pay Seller the sum of $.0717 per kWh. For the
purposes of

                                       -2-

this Agreement, "Point of Delivery" shall be the Steamboat substation 25 kv
source closest to the plant, which source is owned by Purchaser. Seller agrees
to comply with Purchaser's Electric Rules 2 and 15, all special conditions of
Schedule CSPP and all subsequent revisions of said schedule and rules.

                (b)  Monthly bills will be submitted to Purchaser by Seller. The
amount of each bill will be computed on the basis of energy delivered to
Purchaser during the billing period just ended, multiplied by the rate specified
above. The billing period shall be the time interval between two consecutive
meter readings taken for billing purposes. Purchaser shall pay each bill within
fifteen (15) days of the billing date. A monthly penalty of 1.0 percent of the
unpaid balance will be assessed on bills not paid within fifteen (15) days after
the billing date.

          (4)   Term. This Agreement shall be effective upon the date of its
execution and shall continue until a period of ten (10) years has elapsed from
the commencement of the production and sale of electricity by Seller's plant,
and shall continue thereafter from year to year unless terminated by one of the
parties hereto.

          (5)   Design and Operating Equipments. Once Seller's and Purchaser's
facilities are connected, both parties will operate their respective facilities
in accordance with Purchaser's standard 2.2 GN 01 (Exhibit B), which is attached
hereto and incorporated herein by this reference, and the approved facility
wiring diagram and specification

                                       -3-

described in Paragraph 11 below, as well as any subsequent amendments to either
document which are reasonably applicable to Seller's plant and interconnection
facilities. Seller shall be given reasonable prior notice of all such
amendments. The parties acknowledge that with operating experience adjustment of
the operating requirements may be necessary. Seller shall not make any
modification to its facilities which substantially affects performance without
advance notification to Purchaser.

          (6)   Metering. Seller's facility will be metered according to
Metering Option 1, as described in Paragraph 3.1 of Exhibit B.

          (7)   Conditions. The obligations of either party under this Agreement
are conditioned upon the following events having occurred:

                (a)  Seller's attainment of qualifying facility status for the
plant pursuant to the Public Utilities Regulatory Policy Act of 1978 and 18
CFR 292, and any applicable amendments or supplements thereto.

                (b)  Seller's compliance with any applicable portions of General
Order 32 of the Public Service Commission of Nevada and any amendments or
supplements thereto.

                (c)  Approval of the pricing provisions herein as a portion of
Purchaser's purchased power costs by the Public Service Commission of Nevada.

          (8)   Responsibility for Maintenance. It shall be the responsibility
of Seller at its sole cost and expense to maintain all of the facilities,
including all control and

protective devices, from the metering devices to Seller's generation facility.
It shall be the responsibility of the Purchaser at its sole cost and expense to
maintain facilities for the transmission of electrical energy, up to and
including the service drop and the devices for metering electrical energy
installed pursuant to this Agreement.

          Seller agrees to give Purchaser sixty (60) days' written notice of all
scheduled maintenance periods.

          (9)   Special Facilities. Seller shall be responsible for all standard
interconnection costs. In the event it is necessary for Purchaser to install any
special or additional interconnection facilities, including control or
protective devices, line extensions, multiple metering, or reinforcement of its
system to receive or continue to receive the power delivered under this
Agreement, Seller shall reimburse Purchaser for its costs associated with the
installation of such facilities under a separate special facilities agreement.

          (10)  Prior Approval. Equipment specifications and detailed plans for
the installation of Seller's interconnection facilities, control and protective
devices, and facilities to accommodate Purchaser's meters will be submitted to
purchaser for review and advance written approval prior to actual installation.
Such review and written approval are acknowledgements that Seller's facility
complies with Purchaser's requirements only. Purchaser shall not, by reason of
such review and approval or failure to review and approve, be responsible for
strength, details of design, adequacy, or capability of any of Seller's
equipment, nor

                                       -5-

shall Purchaser's acceptance be deemed an endorsement of any item of equipment.
Seller and Purchaser acknowledge that the equipment specifications and detail
plans submitted to Purchaser are intended only for the specific site and
installation described in this Agreement.

          (11)  Right of Entry. Purchaser may enter Seller's premises (a) at any
reasonable time, to inspect Seller's protective devices, or (b) at any time
without notice, to disconnect the interconnection facilities if, in Purchaser's
opinion, a hazardous condition exists and immediate disconnection is necessary
to protect Purchaser's customers, other persons, Purchaser's facilities, or
Seller's facilities from damage.

          Purchaser and Purchaser's escorted visitors may also enter Seller's
premises, with reasonable notice and permission of Seller, to conduct tours of
the generation plant and related facilities and to observe and monitor Seller's
generating facilities.

          (12)  Information Transfer. Seller agrees to make available to
Purchaser upon request any and all information related to the installation,
operation and maintenance of the facility and the use of the resource. Such data
will be treated as confidential and can only be released by Purchaser with
written permission of Seller, which permission shall not be unreasonably
withheld. The parties will cooperate in developing mutually agreeable tests
and/or modifications to be performed on the plant and resource.

                                       -6-

          (13)  Follow-On Plants. If Seller intends to build additional
geothermal generation plant(s) on any portion of the land described in Exhibit
A, or on land pooled, unitized, or combined therewith, and Seller intends to
sell a portion of said plant(s) to another party, Seller shall first offer such
portion to Purchaser at the price and on the terms that would be offered to such
a third party. Any such offers shall be in writing and Purchaser shall have
ninety (90) days from the date of receipt of such an offer to accept or reject
it. Upon receipt of Purchaser's rejection of such an offer, or upon expiration
of the ninety-day period described above, whichever comes first, Seller may
offer the same portion of such plant or plants to a third party or parties. In
no event shall such offer be on different terms or at a lower price than those
offered to Purchaser, unless such terms or price have first been offered to
Purchaser according to the procedure outlined in this section.

          (14)  Additional Resources. If Seller intends to purchase or lease
additional geothermal rights in the Steamboat Springs Known Geothermal Resource
Area (KGRA), or purchase or lease additional land in the KGRA, for the purpose
of developing geothermal resources, Purchaser shall have the right to purchase
up to seventy-five percent (75%) interest in said rights or lands. The purchase
price of any such interest shall be one-third of the Seller's total cost of any
parcel or right, or portion thereof, in

                                       -7-

return for a one-quarter interest in the portion of the rights or lands in which
Purchaser is buying an interest.

          Seller shall give Purchaser written notice of Seller's intent to
acquire such rights or lands at least ninety (90) days prior to such
acquisition. Purchaser shall then have ninety (90) days from its receipt of such
notice to notify Seller of its intent to purchase some or all of the
seventy-five percent (75%) interest available to it. Said notice shall be in
writing and shall specify the amount to be purchased, the purchase price, and
the terms of payment. If Seller does not receive such a notice within the
stated period, Purchaser shall have no further rights to any portion of the
acquisition.

          Upon Seller's receipt of Purchaser's notice, Seller and Purchaser
agree to negotiate in good faith an agreement defining the relative right and
responsibilities of the parties with regard to any subsequent development of the
rights or lands in which Purchaser has bought an interest.

          (15)  Liability and Indemnification. Each party shall indemnify and
hold harmless the other party and the directors, officers, and employees of such
other party against and from any and all loss and liability for injuries to
persons, including employees of either party, and damages, including property of
either party, resulting from or arising out of (a) the engineering, design,
construction, maintenance, or operation of or (b) the making of replacements,
additions, or betterments to, the indemnitor's facilities. This

                                       -8-

provision shall apply notwithstanding the active or passive negligence of the
indemnitee. Neither party shall be indemnified for liability or loss resulting
from its sole negligence or willful misconduct. The indemnitor shall, on the
other party's request, defend any suit asserting a claim covered by this
indemnity and shall pay all costs, including reasonable attorney's fees, that
may be incurred by the other party in enforcing this indemnity.

          (16)  A.   Insurance. During the term of this Agreement, Seller shall
maintain the following insurance:

                (a) Workers' Compensation or self-insurance which satisifies the
applicable requirements of Nevada law. Within thirty (30) days after execution
of this Agreement, Seller shall provide Purchaser with a certificate evidencing

A. INTRODUCTION

   1.0   This document presents Sierra Pacific Power Company's (SPPCo's) policy
         and metering arrangement for the parallel operation of small power
         production and co-generation facilities. In addition, this document
         provides the customer design and operating requirements to be applied
         to a customer owned generation facility of less than 1000 KVA
         generating parallel to SPPCo's system.

   2.0   The Customer Design Requirements and the Customer Operating
         Requirements outline the design specifications, the protective
         equipment, and the operating procedures necessary on the customer's
         part to insure safe, effective operation of the parallel customer
         generation facility.

B. BACKGROUND - DEFINITIONS

   1.0   With energy shortages prevailing and gas-oil supplies diminishing, it
         is very important to conserve energy by increasing efficiency, and to
         reduce gas-oil consumption by encouraging the development of
         non-gas-oil types of generation.

   2.0   Small power production and co-generation are two very effective methods
         of conserving energy and reducing gas-oil consumption.

   3.0   Small power production is exotic generation for which the primary
         fuel/energy sources are wind, hydro, solar, biomass, waste, or
         renewable resources. Small power production facilities do not use
         gas-oil fuels as the primary fuel source.

--------------------------------------------------------------------------------

   4.0   Co-generation is the simultaneous production of electricity and useful
         heat in a way that requires less fuel than the separate production of
         electricity and heat. Co-generation facilities sequentially extract
         energy from a thermal process, and produce electricity and useful
         thermal energy. This recovery of waste heat by-products and the
         simultaneous production of two energy products is a more efficient use
         of gas-oil fuels than the separate production of two energy products.

   5.0   The efficiency of small power production and co-generation can be
         maximized, if the customer's generation is connected parallel to the
         utility's system, so that the excess electricity the customer does not
         use is sold to the utility to be used by other customers.

   6.0   A parallel generation system is designed such that the customer's
         generation can be connected to a bus common with the utility's system.
         Power transfer between the customer's system and the utility's system
         is a common result

C. POLICY STATEMENT

   1.0   It is SPPCo's policy to encourage the development of small power
         production and co-generation facilities with the intent of reducing
         gas-oil consumption and increasing efficiency.

   2.0   SPPCo allows "qualifying" small power production and co-generation
         facilities to generate parallel to the utility's system, so that the
         customer can reduce his power required from SPPCo, and so that the
         customer can sell his energy to SPPCo.

   3.0   The parallel generation must be safely integrated into SPPCo's system
         without degrading the integrity of the existing system, and without
         economically burdening the existing customers.

   4.0   Safety is the primary concern with parallel customer generation because
         of the distinct possibility of back-feed into the distribution system
         that previously was immune to back-feed safety hazards.

   5.0   SPPCo requires the parallel generation customer to install certain
         protective devices, and requires the customer to operate his facility
         in a manner that will prevent injury to customers and SPPCo personnel,
         and will prevent damage to customer and SPPCo equipment.

   6.0   SPPCo requires the parallel generation customer to assume the
         responsibilities described in this document.

D. METERING ARRANGEMENT

   1.0   SPPCo will purchase electricity from qualifying small power production
         or co-generation facilities at a rate that reflects the cost SPPCo can
         avoid as a result of obtaining the electricity.

                        FOR PARALLEL GENERATION                  2.2 GN 01
--------------------------------------------------------------------------------

   2.0   SPPCo will sell electricity to qualifying small power production or
         co-generation facilities based on filed Rate Schedules applicable to
         comparable customers without generation.

   3.0   SPPCo offers two metering options:

         3.1   Netting Generation and Load - Metering Option I

               3.1.1  The customer can choose to have the metering arranged so
                      that: SPPCo purchases the net energy from the customer's
                      generator that the customer does not use: and SPPCo sells,
                      to the customer, the net energy that the customer uses but
                      does not generate.

               3.1.2  When the customer's generation output is greater than his
                      load, SPPCo will purchase the excess energy that the
                      customer does not use. The purchase meters will register
                      only the energy supplied from the customer's system to
                      SPPCo's system.

               3.1.3  When the customer's generation output is less than his
                      load, SPPCo will charge the customer only for the power
                      requirements that are supplied by SPPCo. The billing
                      meters will register only the power requirements supplied
                      from SPPCo's system to the customer's system.

               3.1.4  Both the purchase meters and the billing meters will be
                      uni-directional or not allowed to reverse rotation.

               3.1.5  If the applicable rate schedule requires demand metering,
                      the demand meter will register only the demand supplied
                      from SPPCo's system to the customer's system. This demand
                      meter will be used to determine the billing demand and the
                      applicable rate schedule.

                      It is possible that the customer's generation could reduce
                      his demand enough to move the customer to a different rate
                      schedule.

         3.2   Separate Generation and Load - Metering Option II

               3.2.1  The customer can choose to have the metering arranged so
                      that SPPCo purchases 100% of the customer's generation
                      output, and so that SPPCo sells, to the customer, 100% of
                      his load requirements.

                        FOR PARALLEL GENERATION                  2.2 GN 01
--------------------------------------------------------------------------------

               3.2.2  The customer's generation and load shall be treated
                      separately and independently. For example, if a co-
                      generation facility produces 50 KW and consumes 30 KW, it
                      would be treated the same as another qualifying facility
                      that produces 5O KW, and is located next to a shop that
                      uses 30 KW.

               3.2.3  The customer is not allowed to connect load on the
                      generator side of the purchase meter, other than the
                      minimal load associated with the generator.

                      The customer should note that the purchase meter will be
                      bi-directional. The purchase meter will reverse its
                      rotation if the customer's generator loses power and goes
                      into a motoring state or in any way places a load on the
                      line. SPPCo may require a reverse power relay to prevent
                      bi-directional powerflow or may require additional
                      metering.

E. CUSTOMER DESIGN REQUIREMENTS

   This section provides the minimum design specifications that the customer's
   generation facility must meet, and specifies the minimum protective equipment
   that the customer's generation facility must have installed.

   The design specifications and protective equipment listed are intended to
   protect other customers and SPPCo from damage that could be caused by the
   parallel generation facility.

   These requirements are not intended to protect the customer's generation
   facility from every possible source of damage. The parallel generation
   customer may wish to install additional protective equipment to protect his
   generation facility.

   1.0   Applicable Codes - The customer's installation must meet all applicable
         national, state, and local construction and safety codes.

   2.0   Relay Settings - Electrical Schematics Approval - All protective device
         relay settings and all electrical schematics must be approved in
         writing by SPPCo.

   3.0   Customer Responsibilities - The customer will purchase, own, operate,
         and maintain the required protective equipment.

   4.0   Additional Protective Equipment - SPPCo reserves the right to require
         additional protective equipment and safety measures as further
         experience may dictate.

--------------------------------------------------------------------------------

   5.0   Synchronous and Induction Generation - Capacity less than 100 KVA

         5.1   Full Load Rejection - The customer's generation facility must be
               designed with the capability or protection to withstand sudden
               loss of load.

         5.2   De-energized SPPCo Circuit - Electrical relays must be provided
               to prevent the customer's generator from being connected parallel
               to SPPCo's system if SPPCo's system is de-energized.

         5.3   Generator Circuit Breaker - The generator must have a generator
               circuit breaker capable of interrupting the maximum anticipated
               fault current and isolating the customer's generation from
               SPPCo's system. The generator circuit breaker must be equipped
               with thermal-magnetic overcurrent or equivalent devices on each
               phase.

               The generator circuit breaker must be grouped with the main
               service disconnects, readily accessible, and nearest the point of
               entrance of the service-entrance conductors as specified in the
               NEC 230-72.

               The generator circuit breaker or enclosure must be capable of
               being locked and/or sealed by SPPCo personnel to physically
               prevent closing the circuit breaker when SPPCo personnel are
               working on the line.

         5.4   Voltage Sensing Location - The voltage sensing location for the
               protective relays must be on the SPPCo side of any customer
               operated disconnect (see sheets 8-9).

         5.5   Overcurrent Protection - Phase overcurrent protection is required
               to protect the generator from fault current and overload current.
               Ground overcurrent protection is required, if applicable.

         5.6   Over/Under Voltage Protection - Overvoltage and undervoltage
               protection is required. Time delay is recomended on the voltage
               relays.

         5.7   Underfrequency Protection - Underfrequency protection without
               time delay is required. Overfrequency protection may be required.

         5.8   Loss-of-Phase Protection - Negative sequence current or
               loss-of-phase protection is required on three phase generators.
               The customer is responsible for protecting his generator from
               negative sequence currents that could overload and severely
               damage the customer's generator. Negative sequence currents will
               occur during single phasing conditions on SPPCo's system.

--------------------------------------------------------------------------------

         5.9   Synchronizing Equipment - Synchronous generators require
               synchronizing equipment to be provided at the main generator, and
               other breakers as necessary. The generator must be brought
               on-line parallel to SPPCo's system by one of the following
               methods:

               a)     Automatic synchronizing.

               b)     Manual synchronizing - note that a synchronizing check
                      relay is also required with manual synchronizing to
                      protect the customer's generator from excessive transient
                      torques that could damage the customer's equipment.

               c)     Induction starting - provided that the inrush current does
                      not cause voltage flickers on SPPCo's system greater than
                      4%.

         5.10  Voltage Regulation Equipment - Synchronous generators require
               voltage regulation equipment to maintain the Customer's service
               voltage within 5% above or below nominal service voltage (e.g.
               120 volts +/- 6 volts). Customers in California are required to
               maintain their service voltage in accordance with the
               Conservation Voltage Reduction Program (e.g. 114 volts to 120
               volts).

         5.11  Primary Voltage Changes - The generator exciter system and
               voltage regulation equipment on synchronous generators must be
               capable of operating subject to normal primary voltage changes on
               SPPCo's system ranging from 5% above or below nominal primary
               voltage (e.g. 24.9 KV +/- 5%).

   6.0   Synchronous and Induction Generation: Capacity 100 KVA - 1000 KVA

               The requirements described in section 5.0 also apply to 100 KVA
               to 1000 KVA generation.

         6.1   Overfrequency Protection - Overfrequency in addition to
               underfrequency protection is required. Frequency protection shall
               not have time delay.

         6.2   Power Factor Correction - Power factor correction could be
               required at SPPCo's option on induction generators greater than
               100 KVA.

   7.0   D.C. Generation With Inverter

         7.1   All requirements listed for synchronous generators shall apply to
               d.c. generator/inverter combinations with the following
               exceptions:

               a)     The power factor shall be within the range of 0.9 lagging
                      to 0.9 leading over the full range of power output.

               b)     The synchronizing check relay is not required on line
                      commutated inverters that derive their waveform and
                      frequency from SPPCo's signal.

               c)     See section H-6.0 for harmonic voltage and current
                      operating requirements.

F. CUSTOMER DESIGN RECOMMENDATIONS

   This section provides recommended protection that the customer should
   consider adding to the generation facility. Again, the previus minimum design
   requirements are not intended to protect the customer's generation facility
   from every possible source of damage.

   Additional equipment beyond the minimum required and recommended protection
   may be desired to fully protect the customer's generation facility.

   1.0   Over/Under-Speed Protection - Overspeed and underspeed protection are
         recommended.

   2.0   Reverse Power Protection - Anti-motoring or reverse power protection is
         recommended. A lack of sufficient power at the prime mover will cause
         the customer's generator to motor instead of generate. This condition
         can be very costly to the customer.

   3.0   Impedance Neutral Grounding - Impedance neutral grounding is
         recommended.

   4.0   Voltage Surge Protection - Voltage surge protection is recommended.

   5.0   Generator Differential Protection - Generator differential protection
         is recommended.

   6.0   Loss of Excitation Protection - Loss of excitation protection is
         recommended.

   7.0   Unity Power Factor - It is recommended that synchronous generators be
         set to hold near-unity power factor.

   8.0   Relay Targets - Targets or devices that indicate the operation and
         status or a relay are recomended. Targets are very important to
         troubleshooting the generation facility.

G. INDUCTION AND SYNCHRONOUS GENERATION DIAGRAMS

   Typical one-line diagrams illustrating the required equipment for both
   synchronous and induction generators follow. Variations to these designs are
   acceptable provided the intent of this section is met, and provided the
   design is reviewed and approved in writing by SPPCo.

H. CUSTOMER OPERATING REQUIREMENTS

   This section provides the operating requirements that the customer must
   follow, and the responsibilities that the customer must assume for operating
   his generation parallel to SPPCo's system.

   1.0   Quality of Service - The operation of the customer's generation
         facility must not reduce the quality of service to other SPPCo
         customers. No abnormal voltages, currents, frequencies, or
         interruptions are permitted.

   2.0   De-energized SPPCo Circuit - The customer will at no time energize a
         de-energized SPPCo circuit, without the permission and the supervision
         of SPPCo personnel.

   3.0   Bypassing Relays - The customer shall not bypass any of the protective
         relays or equipment.

   4.0   Inhibited Parallel Operation - If while operating parallel to SPPCo's
         system, or while attempting to bring the generating system on-line and
         operate parallel to SPPCo's system, any of the protective relays or
         devices operate inhibiting parallel operation, the customer will follow
         these procedures prior to attempting parallel operation with SPPCo
         again:

         4.1   Determine if SPPCo's circuit is energized or de-energized by
               checking the status of the relays described in Section E-5.2
               and/or contacting the local SPPCo office.

         4.2   If it is determined that the SPPCo circuit is and has been
               continuously energized, then the customer will not attempt to
               reconnect his system parallel to SPPCo's system, until the cause
               of protective device operation has been corrected, and it has
               been determined that the customer's system is in proper operating
               condition.

         4.3   If it is determined that the SPPCo circuit is de-energized, the
               customer must not attempt to reconnect his system and operate
               parallel with SPPCo's system until he has confirmed that power
               has been restored and SPPCo's circuit is energized.

         4.4   The customer is not prohibited from isolating his system and
               supplying his own load while SPPCo's circuit is de-energized.

               NOTE: The designs and equipment outlined 1n this document do not
               provide for the customer to isolate his system and supply his own
               load while SPPCo's circuit is de-energized. If the customer
               wishes to do this, he must install additional protective
               equipment subject to a more complex and stringent design. These
               cases will be studied on an individual basis.

--------------------------------------------------------------------------------

   5.0   Automatic Reclosing - The customer is not allowed to automatically
         reclose parallel to SPPCo's System if any of the protective devices
         operate.

         However, if the customer ceases parallel operation with SPPCo because
         of an anti-motoring operation or lack of applicable power source (wind,
         water, etc.), the customer is allowed to automatically reclose parallel
         to SPPCo system when the energy source resumes to sufficient amounts.

         The distinctions between disallowing or allowing automatic reclosing
         are:

         a)    Automatic reclosing is disallowed if parallel operation has been
               ceased due to an abnormal or dangerous condition (fault current,
               overloads, over or under voltage, over or under frequency).

         b)    Automatic reclosing is allowed if parallel operation has been
               ceased due to a lack of sufficient power to the prime mover (lack
               of wind, water, etc.).

   6.0   Harmonics - The customer's generation facility shall not cause
         excessive distortion of the sinusoidal voltage wave. The maximum
         allowable total root-mean-suqare (RMS) harmonic current is 5% of the
         fundamental 60 Hz RMS current. The maximum allowable total RMS harmonic
         voltage (all harmonics) is 2% of the nominal AC voltage. In addition,
         the RMS voltage of any single voltage harmonic shall not exceed 1%.

   7.0   Damage to Other Customer - The customer is responsible for damage
         caused to other customers and to SPPCo as a result of misoperating or
         malfunction of his generation facility or protective equipment.

   8.0   Damage to Generation Customer - SPPCo is not responsible for damage
         caused to the customer's facility as a result of acts over which SPPCo
         has no control.

   9.0   SPPCo Automatic Reclosing - SPPCo is not responsible for damage caused
         to the customer's facility as a result of SPPCo automatic or manual
         reclosing.

                                 ****WARNING****

               RECLOSING CAN CAUSE LOSS OF SYNCHRONISM BETWEEN THE
               CUSTOMER'S SYSTEM AND SIERRA'S SYSTEM, THAT CAN IN
                  TURN SEVERELY DAMAGE THE CUSTOMER'S EQUIPMENT

--------------------------------------------------------------------------------

         9.1   If feasible, and at the customer's option and expense,
               communications between the customer's circuit breaker and SPPCo's
               circuit breaker can be provided to reduce the risk of
               out-of-synchronism damage. Other measures for protection can be
               considered and implemented if feasible.

   10.0  Scheduled Maintenance and Testing - The customer is responsible for
         performing scheduled maintenance and testing on the generation facility
         and the protective equipment to keep the facility in proper operating
         condition. SPPCo reserves the right to inspect the customer's facility
         to check for a hazardous condition or a lack of scheduled maintenance
         or testing.

   11.0  Discontinue Parallel Generation With Notice - SPPCo reserves the right
         to discontinue parallel generation with reasonable prior notice for any
         of the following reasons:

         a)    SPPCo will be performing non-emergency maintenance or repair of
               utility facilities.

         b)    The customer's generation reduces the quality of service to other
               customers.

         c)    Inspection of the customer's facility reveals a lack of scheduled
               maintenance or testing.

   12.0  Discontinue Parallel Generation Without Notice - SPPCo reserves the
         right to open the main disconnecting device and cease parallel
         generation without prior notice in the event of a system emergency or
         hazardous condition.

         12.1  The customer is advised that his generation facility must be
               capable of withstanding load rejection of this nature. SPPCo is
               not responsible for any damage caused to the customer's equipment
               as a result of disconnection from SPPCo's system.
