In the circumstances set forth in this Section 11, a Project Partnership may be compelled to offer to sell, and to then sell, its Interest to one or more of the other Project Partnerships. In all such circumstances, the offeror-Project Partnership is referred to herein as the "Selling Project Partnership" and the offeree-Project Partnership or Project Partnerships are collectively referred to herein as the "Remaining Project Partnerships". 11.2. Voluntary Sales. (a) no partial sales or other partial transfers of Interests shall be permitted except to other Project Partnerships; (b) no Project Partnership shall be permitted to sell or otherwise transfer its Interest separately from its Individually-Owned Assets; and (c) no Project Partnership shall have the right to sell or otherwise transfer its entire Interest to any other person or entity that is not a Project Partnership, or surrender its interest in the Cotenancy Assets or any part thereof to the BLM, unless it first offers to sell such Interest to the other Project Partnerships. 11.2.1. The Interest which the Selling Project Partnership intends to sell, transfer or surrender shall first be offered in writing (such written offer being hereafter referred to as the "Offering Notice") to all the Remaining Project Partnerships at the stated price at which the Interest is proposed to be sold or otherwise transferred to such third person or entity and on the proposed terms thereof. The Remaining Project Partnerships, collectively and individually, shall have a period of thirty (30) days after the giving of the Offering Notice (as determined in accordance with Section 15.3 hereof) in which to accept or reject said offer (the "Offer Period"). 11.2.2. If the Remaining Project Partnerships, or any of them, accepts the offer within the Offer Period, then the purchase and sale shall be completed as soon as reasonably possible, and all costs and expenses associated with such purchase and sale shall be borne by the Selling Project Partnership. If no Remaining Project Partnership elects, within the Offer Period, to purchase the Selling Project Partnership's Interest, then the Selling Project Partnership may (a) surrender its interest in the Cotenancy Assets or any thereof to the BLM or (b) sell or otherwise transfer its Interest to any third person or entity during the three (3) month period immediately following the expiration of the Offer Period, but not at a price lower than the 10 proposed price or on terms more favorable to the purchaser than the proposed terms set out in the Offering Notice. After the expiration of said three (3) month period, the Selling Project Partnership's interest may not be sold, transferred or surrendered without that Interest again first being re-offered to the Remaining Project Partnerships in accordance with Section 11.2.1 hereof. 11.3. Other Events Constituting Offers to Sell. 11.3.1. Upon the occurrence of any of the following events (each, an "Offer To Sell Event"), such event shall be deemed to constitute an offer by the affected Project Partnership, or its principals or successors-in- interest, or the trustee of its estate, as the case may be (the appropriate one of which shall be deemed to be the Selling Project Partnership for purposes of this Section), to sell its entire Interest to the other Project Partnerships, or any of them, for the price determined under Section 11.3.2 hereof: a. The dissolution of such Project Partnership; b. The voluntary or involuntary filing of a petition in bankruptcy or for protection under similar insolvency Laws, or any general assignment of assets for the benefit of creditors; or c. Any Default under (and as that term is defined in) Section 13.1 hereof. 11.3.2. Upon an Offer To Sell Event, the Remaining Project Partnerships, collectively or individually, shall have the right to purchase the Selling Project Partnership's Interest for an amount equal to the sum of the then-current fair market value of (a) such Interest and (b) any Individually- Owned Assets owned by the Selling Project Partnership, by giving written notice to the Selling Project Partnership within thirty (30) days after the occurrence of the Offer To Sell Event. If the Selling Project Partnership and the Remaining Project Partnerships cannot agree on such fair market value, then, within fifteen (15) days after a written demand by the Selling Project Partnership or the Remaining Partnerships, the parties shall either (i) jointly appoint an M.A.I. appraiser for the purpose of determining said fair market value or (ii) failing such joint action, each separately designate an M.A.I. appraiser. In the latter case, within five (5) days after their appointment, the designated appraisers shall jointly designate a third M.A.I. appraiser, whose determination of such Interest's and Individually-Owned Assets' fair market value shall be binding and conclusive. The failure of the Selling Project Partnership or the Remaining Partnerships to timely appoint an appraiser shall be deemed an express approval of the other party's appraiser, and such appraiser's appraisal shall determine and be the fair market value. The fees of the appraiser(s) shall be paid in equal shares by said parties. 11.4. Notwithstanding anything contained in this Agreement, the Governing Documents or any rule of law or equity which would otherwise allow the Project Partnerships to partition or to seek or obtain a partitioning of the Cotenancy Assets, the Project Partnerships shall not have and hereby waive the right to partition all or any portion of the Cotenancy Assets, or to make application to any court or authority or to commence or prosecute any action or proceeding for partition of the Cotenancy Assets. Each Project Partnership and the Lender shall 11 be entitled to a decree or order restraining or enjoining such partition, application, action or proceeding upon any breach of the provisions of this Section 11.4. The Project Partnerships acknowledge and agree that they have been paid full consideration for the waiver herein provided. The Lender is hereby made a third-party beneficiary of the waiver and covenants herein provided; and the Project Partnerships agree that they will not participate in or permit any revocation, termination or amendment of such waiver or covenants without the prior written consent of the Lender. 12. TRANSFER, TERMINATION AND AMENDMENT OF THE LEASES AND THE RIGHT OF WAY GRANTS. Except as expressly provided herein, the Cotenancy Assets or any portion thereof may be sold or otherwise transferred, or may be amended or terminated, only upon (a) the written agreement of all of the Project Partnerships and (b) approval of the Lender if such approval is required under Section 14 hereof. Subject to Section 14 hereof, each of the Project Partnerships hereby covenants and agrees to execute all documents as may be required to effect any such approved sale, other transfer, amendment or termination. Subject to the terms and conditions of the Financing Documents (as that term is defined in the Indenture), the proceeds from any sale of the Cotenancy Assets or any specific portion thereof shall be divided among the Project Partnerships in proportion to their respective Interests; provided, however, that such division shall be equitably adjusted to take into account the fair market value (which shall be determined in a manner consistent with Section 11.3.2 hereof) of any Individually-Owned Assets existing on the Property on the date of such sale. All costs and expenses directly resulting from the sale or other transfer of the Cotenancy Assets, including, without limitation, escrow costs, title insurance premiums and documentary transfer taxes, shall be divided among the Project Partnerships in proportion to their respective Interests. 13. DEFAULT AND REMEDIES 13.1. Events of Default; Default. If a Project Partnership shall fail to perform its obligations hereunder in any material respect (an "Event of Default"), then such Project Partnership shall not be in Default hereunder unless such Project Partnership shall have failed to cure such Event of Default within thirty (30) days after such Project Partnership has received written notice of such Event of Default ("Notice of Default") from a non-defaulting Project Partnership or the Operator; provided, however, that if the nature of such obligation or obligations is such that more than thirty (30) days are required, in the exercise of commercially reasonable diligence, for performance of such obligation(s), then such Project Partnership shall not be in Default if it commences such performance within such thirty (30) day period and thereafter pursues the same to completion with commercially reasonable diligence. A Project Partnership shall be in "Default" hereunder if its Event of Default is not cured within the time set forth above in this Section. 13.2. Remedies. In addition to all other remedies permitted by Law or under this Agreement (all of which shall be cumulative), the Project Partnership or Project Partnerships, as the case may be, that is/are not in Default hereunder, shall have the right to purchase the Interest of the Project Partnership that is in Default hereunder, as provided in Section 11.3 hereof. 12 13.3. Performance By Non-Defaulting Project Partnership(s). In the event that any Project Partnership fails to make any payment or perform any obligation required to be made or performed by such Project Partnership hereunder, under the Leases or under the Right of Way Grants (regardless whether the same constitutes a Default hereunder), then any other Project Partnership or the Operator shall be entitled (but not obligated) to make the required payment or perform the required obligation in fulfillment of such Project Partnership's obligations, whereupon the defaulting Project Partnership shall, upon demand, reimburse the paying or performing Project Partnership(s) or the Operator, as the case may be, for the amount of such payment and the cost of such performance. 13.4. Specific Performance. The Project Partnerships agree that damages may be an inadequate remedy for a Default under this Agreement, the Leases or the Right of Way Grants and that each Project Partnership shall be entitled to seek injunctive and other equitable relief against any other Project Partnership to prevent or eliminate such Default. 14. LENDER PROTECTIONS 14.1. The following provisions are for the benefit of the Lender, and shall be in effect while there exists any outstanding amount payable, or any performance required, under the Indenture (as that term is defined below), including, without limitation, any amount payable under the Senior Secured Notes (as that term is defined in the Indenture). Once all of the outstanding amounts payable and all performance required under the Indenture have been fully paid and performed, all references in this Agreement to the Lender shall be deemed null and void and all such provisions shall, without any further actions, have no further force and effect. 14.2. The Lender shall have the right, but not the obligation, upon the occurrence of an Event of Default, to (a) make any payments due under this Agreement or the Governing Documents, and (b) do any other act or thing that may be necessary or appropriate to be done in the performance and observance of the terms hereof. All payments so made and all things so done and performed by the Lender shall be as effective to prevent or cure any Event of Default under this Agreement and the Governing Documents as they would have been if made, done and performed by the Project Partnerships, and each Project Partnership agrees to accept such performance, payment and cure. Each Project Partnership agrees to make all payments (if any) to be made by it to a defaulting Project Partnership directly to the Lender upon receipt of the Lender's written instructions to that effect. 14.3. As used herein, the term (a) "Lender" means U.S. Bank Trust National Association, not in its individual capacity but solely as trustee and collateral agent pursuant to the Indenture of even date herewith (the "Indenture") among it, Caithness Coso Funding Corp., as issuer, and the Project Partnerships as borrowers and guarantors, and its agents, representatives, successors and assigns, (b) "Lender's Lien" means the hypothecation, mortgage or pledge of all or any portion of the Project Partnership Assets (as that term is defined below) to the Lender as security for the repayment of the indebtedness and performance of the obligations under the Indenture, the Guarantees or any other Financing Document (as those terms are defined in the Indenture) and (c) "Project Partnership Assets" means, collectively, a Project Partnership's right, title and interest in and under this Agreement and the Governing 13 Documents and in and to the Property, the Cotenancy Assets and any Individually- Owned Assets. 14.4. Each Project Partnership agrees for the benefit of the Lender that it will not, without the prior written consent of the Lender (which consent shall be given or withheld on the basis of the documents governing the relationship between the Lender and such Project Partnership): (a) amend or modify, or take any action causing, consenting to or accepting the amendment or modification of this Agreement or the Governing Documents, if such amendment or modification would reduce the rights or remedies of the Lender hereunder or impair or reduce the security for the Lender's Lien, or (b) cancel, terminate or suspend, or take any action causing, consenting to or accepting the cancellation, termination or suspension of, this Agreement or the Governing Documents. 14.5. Each Project Partnership shall deliver to the Lender a duplicate copy of any and all Notices of Default that it may from time to time deliver to a defaulting Project Partnership hereunder or under the Governing Documents, and such copies shall be delivered to the Lender at the same time such Notices of Default are delivered to such defaulting Project Partnership. No such Notice of Default shall be deemed to have been given to a defaulting Project Partnership hereunder unless and until a copy thereof shall have been given to the Lender. 14.6. Upon a defaulting Project Partnership's failure to cure any Event of Default hereunder or under any Governing Document within the time provided in Section 13.1 hereof, then the Lender shall have an additional sixty (60) days thereafter to cure such Event of Default; provided, however, that if such Event of Default cannot reasonably be cured within such additional sixty (60) day period, then the Lender shall have such additional time to cure such Event of Default as may be reasonably necessary. Any Event of Default that cannot be cured by the Lender shall nevertheless be deemed to have been cured and remedied if (a) on or before sixty (60) days after receiving such Notice of Default, the Lender shall have acquired the defaulting Project Partnership's then-remaining Project Partnership Assets, or shall have commenced foreclosure or other appropriate proceedings for such purposes and shall be prosecuting such proceedings to completion with commercially reasonable diligence, (b) the Lender shall have fully cured within such sixty (60) day period any failure on the part of the defaulting Project Partnership to perform its monetary obligations hereunder and shall thereafter continue to perform such monetary obligations and (c) after obtaining the defaulting Project Partnership's then-remaining Project Partnership Assets, the Lender commences performance of the obligations of the defaulting Project Partnership hereunder. All rights of the Project Partnerships to terminate this Agreement as a result of the occurrence of an Event of Default hereunder shall be expressly conditioned upon (i) the Lender having first received a copy of the Notice of Default as and when provided in Section 14.5 hereof and (ii) the Lender having failed to cure the Event of Default or acquire possession of the defaulting Project Partnership's Project Partnership Assets or commence foreclosure or other appropriate proceedings as set forth, and within the time specified, in this Section 14.6. 14.7. If the Lender is prohibited by any process or injunction issued by, or by reason of any action of, any court having jurisdiction over any bankruptcy, reorganization, insolvency or other debtor-relief proceeding from commencing or prosecuting foreclosure or other appropriate proceedings, then the times specified in Section 14.6 hereof for commencing or 14 prosecuting such foreclosure or other proceedings shall be extended for the period of such prohibition; provided, however, that the Lender shall have fully cured, within the time specified in Section 14.6 hereof, any failure on the part of the defaulting Project Partnership to perform its monetary obligations hereunder, and shall thereafter continue to perform such monetary obligations when and as due hereunder. 14.8. The transfer of a defaulting Project Partnership's Project Partnership Assets or any part thereof to the Lender and/or to one or more purchasers or grantees (a) at a foreclosure sale by judicial or nonjudicial foreclosure and sale, (b) by a conveyance in lieu of foreclosure or (c) by any other assignment or conveyance, including, without limitation, by the Lender or such other purchaser(s) or grantee(s) following foreclosure and sale, or as a result of any other legal proceeding, shall not require the consent of the other Project Partnerships, and such other Project Partnerships agree that upon such foreclosure, sale, conveyance, assignment or other proceeding, they shall recognize the Lender or such other purchaser(s) or grantee(s) as the successor to the defaulting Project Partnership under this Agreement and the Governing Documents; provided, however, that, subject to Section 14.10 hereof, the Lender or such purchaser(s) or grantee(s) assumes the obligations of the defaulting Project Partnership under this Agreement, the Leases and/or the Exchange Agreement and pays all amounts in arrears due from the defaulting Project Partnership to the other Project Partnerships hereunder. 14.9. In the event that this Agreement or the Exchange Agreement is rejected by a trustee or debtor-in-possession in any bankruptcy or insolvency proceeding, or if this Agreement or the Exchange Agreement is terminated for any reason other than an Event of Default which could have been but was not cured by a Lender as provided in this Section 14, and if, within sixty (60) days after receiving notice of such rejection or termination, the Lender shall so request, then, so long as the Lender has cured any monetary default by the defaulting Project Partnership and is making commercially reasonable efforts to cure any non-monetary default by the defaulting Project Partnership as provided herein, the other Project Partnerships shall execute and deliver to the Lender or its designee one or more new agreements, which new agreement(s) shall be on the same terms and conditions as this Agreement and/or the Exchange Agreement (as the case may be), for the remaining term of this Agreement and/or the Exchange Agreement (as the case may be) before giving effect to such rejection or termination. 14.10. The Lender or any such purchaser(s) or grantee(s) shall not have any duty, obligation or liability under this Agreement or the Governing Documents prior to the time of its entry into physical possession of a Project or its commencement of performance of a defaulting Project Partnership's obligations under this Agreement or the Governing Documents or under a new agreement entered into as provided in Section 14.9 hereof, and shall not otherwise be required to perform (or be subject to any defenses or offsets by reason of) any defaulting Project Partnership's other obligations under this Agreement or the Governing Documents that were unperformed at such time. In the event that the Lender elects to perform a defaulting Project Partnership's obligations under this Agreement and/or the Governing Documents, or to enter into a new agreement as provided in Section 14.9 hereof, then the Lender shall not have any personal liability to any Project Partnership for the performance of such obligations, and the sole recourse of such Project Partnerships in seeking the enforcement of such obligations shall be to the Lender's interest in the defaulting Project Partnership's Project Partnership Assets. In the event that the Lender assigns its interest in this Agreement, the Governing Documents or a new 15 agreement entered into pursuant to Section 14.9 hereof to any person or entity, then the Lender shall be released from any further liability hereunder. 14.11. The Project Partnerships shall cooperate in including herein, by suitable amendment from time to time, any provision which the Lender reasonably requests for the purpose of implementing or amending the provisions of this Section 14 or affording the Lender reasonable protection of its Lender's Lien in the event of a default by a Project Partnership; provided, however, that the Project Partnerships shall not be required to include herein any additional term or provision which materially impairs the rights of the non-defaulting Project Partnerships under this Agreement. Each of the Project Partnerships agrees to execute and deliver (and to acknowledge, if necessary for recording purposes) any document or instrument reasonably necessary to give effect to any such provision. 14.12. Each of the Project Partnerships and the Operator shall, upon not less than ten (10) days prior written notice from a requesting Project Partnership or from the Lender, execute an estoppel certificate (a) certifying that this Agreement and the Governing Documents are in full force and effect and have not been modified, (b) certifying that to the best of such Project Partnership's knowledge there are no uncured events of default under this Agreement or the Governing Documents (or, if any such uncured events of default exist, stating with particularity the nature thereof) and (c) containing any other certifications as may reasonably be requested. Any such statements may be conclusively relied upon by the requesting Project Partnership or the Lender. The failure of a Project Partnership or the Operator to deliver such statement within such time shall be conclusive upon such Project Partnership and the Operator that (i) this Agreement and the Governing Documents are in full force and effect and have not been modified and (ii) there are no uncured events of default by any Project Partnership under this Agreement or the Governing Documents. 14.13. Each Project Partnership agrees to have its successor under this Agreement and the Governing Documents assume in writing its obligations under this Agreement and the Governing Documents; provided, however, that nothing contained herein shall be deemed a consent by the Lender to any assignment that is prohibited, or to which the Lender may withhold its consent, under the Financing Documents (as that term is defined in the Indenture). 14.14. At the Lender's option, this Agreement, the Governing Documents or any thereof shall be subordinated to the Lender's Lien and/or to any encumbrance now of record or recorded after the date of this Agreement. Further, at the Lender's option, the lien of any mortgage, deed of trust or security interest hereafter encumbering all or any portion of a Project Partnership's Project Partnership Assets shall be subordinated to this Agreement, the Governing Documents or any thereof, and/or to the Lender's Lien. 14.15. All insurance and condemnation proceeds payable to the Project Partnerships under this Agreement or any of the Governing Documents as a result of damage, destruction or condemnation of any portion of the Property shall be paid to the Lender for handling in accordance with the terms of the Financing Documents. The Project Partnerships shall not enter into any settlement or adjustment relating to such proceeds without the prior written consent of the Lender. 16 14.16. The Project Partnerships agree that, upon the occurrence of an event of default hereunder, under a Governing Document or under any of the Financing Documents, the Lender or a receiver shall have the right to enter, possess and use the Project Partnership Assets at such reasonable times and manner as are necessary or desirable to effectuate the remedies and enforce the rights of the Lender under the Financing Documents. 14.17. This Agreement and the Conveyance Documents shall be binding upon the successors and assigns of the Project Partnerships and shall inure, together with the rights and remedies of the Lender hereunder, to the benefit of the Project Partnerships and the Lender and their respective successors, transferees and assigns. Each Project Partnership agrees to confirm such continuing obligation in writing upon the reasonable request of any other Project Partnership, the Lender or their respective successors, transferees or assigns. 15 GENERAL PROVISIONS 15.1 Effect of This Agreement. This Agreement shall automatically attach and apply (a) to the Leases and the CLC Pre-Existing Assets at such time as the Lease Assignment is completed and (b) to the MidAmerican Pre-Existing Assets at such time as the Operator Assignment is completed, in each case without the need for any other documentation or consent by or from any party hereto; and, at such time, each Project Partnership's rights in and to all of the Cotenancy Assets, the Property and Individually-Owned Assets shall be governed by this Agreement. 15.2 Indemnities. 15.2.1 In addition to any other indemnities set forth herein, each Project Partnership (the "Indemnifying Project Partnership") shall indemnify, defend and hold harmless the other Project Partnerships (each, an "Indemnified Project Partnership") from and against any and all losses, damages, liabilities, claims, judgments, liens, penalties, costs and expenses, including, without limitation, reasonable attorneys' and consultants' fees, which may be imposed upon or incurred by such the Indemnified Project Partnership or asserted against such Indemnified Project Partnership by any third person or entity in connection with (a) any acts, omissions, operations or activities of the Indemnifying Project Partnership on or in connection with (i) the Cotenancy Assets or the Property or (ii) such Indemnifying Project Partnership's Individually-Owned Assets and (b) any Event of Default or Default by the Indemnifying Project Partnership in the performance of its obligations under this Agreement. 15.2.2 The Project Partnerships acknowledge that when CLC acquired the Leases from the Los Angeles Department of Water and Power ("LADWP"), it made certain covenants and gave certain indemnities to LADWP. Without limiting the generality of the Lease Assignment, the Project Partnerships hereby agree to abide by such covenants and to assume such indemnities in proportion to their respective Interests. 15.3 Notices. Any notices, statements, demands, correspondence or other communications required or permitted to be given hereunder shall be in writing and shall be given (a) personally, (b) by certified or registered mail, postage prepaid, return receipt requested, or (c) by overnight or other courier or delivery service, freight prepaid, (i) to the recipient Project 17 Partnership or Project Partnerships c/o Caithness Energy, L.L.C., 1114 Avenue of the Americas, 41st Floor, New York, New York 10036, or to such other address as a Project Partnership may from time to time designate in writing to the other Project Partnerships and the Lender and (ii) to the Lender at One California Street, Suite 400, San Francisco, California 94111, Attention: Trust Officer, or to such other address as the Lender may from time to time designate in writing to the Project Partnerships.

Except with respect to the rights of the Operator as provided herein (which Operator shall be an express third party beneficiary of the covenants contained in this Agreement, with rights and benefits under, and the ability to enforce, this Agreement), the covenants contained herein are made solely for the benefit of the parties hereto, the Lender, and their respective successors and assigns as permitted herein, and shall not be construed as having been intended to benefit any person or entity who is not a party to this Agreement. 15.5 Attorney's Fees and Costs. If any Project Partnership institutes any legal action or other proceeding for the enforcement, termination, cancellation or rescission hereof, or for damages for the breach hereof, the prevailing Project Partnership or Project Partnerships in such action or proceeding shall be entitled to recover its/their reasonable attorney's fees and all its/their court and other costs. 15.6 Amendment. Subject to Section 14 hereof, no amendment or modification of this Agreement or any provision hereof shall be effective unless in writing and signed by all of the Project Partnerships at the time of the amendment. 15.7 Integration. This Agreement, the Conveyance Documents, the Acquisition Agreement and the Governing Documents collectively contain all agreements of the Project Partnerships with respect to the subject matter hereof, and all other prior or contemporaneous agreements, understandings, correspondence and negotiations among the Project Partnership, whether oral or written, pertaining to the subject matter of this Agreement, shall be of no further force or effect, and are superseded hereby. 15.8 Severability. The invalidity or unenforceability of any provision hereof as determined by a court of competent jurisdiction shall in no way affect the validity and enforceability of any other provision hereof; and in the event that any part or provision of this Agreement shall be determined by a court of competent jurisdiction to be invalid or unenforceable, then the remaining portions of this Agreement which can be separated from the invalid, unenforceable provisions shall, nevertheless, continue in full force and effect. 15.9 Successors and Assigns. The Cotenancy Assets, the Individually- Owned Assets and the Interests shall be held, conveyed, assigned, hypothecated, encumbered and leased, and the Property shall be used and occupied, subject to the covenants, terms and 18 provisions set forth in this Agreement, which covenants, terms and provisions shall run with the land, and shall be binding upon and inure to the benefit of each Project Partnership and each other person and entity having any interest therein during their ownership thereof, and their respective permitted grantees, heirs, successors and assigns, and shall create privity of contract and estate among the Project Partnerships and their respective grantees, heirs, successors and assigns. 15.10 Further Assurances; Cooperation. Each Project Partnership shall, from time to time, execute, cause to be acknowledged and deliver such documents or instruments, and provide such certificates, as any other Project Partnership may reasonably request to carry out and fulfill the transactions, and permit the exercise and performance of the rights and obligations, as are contemplated hereunder. Each Project Partnership shall cooperate with each other Project Partnership to fully effectuate the purposes and intent of this Agreement. 15.11 Construction. This Agreement shall be subject to, governed by, and construed in accordance with the Laws of the State of California and applicable federal Law. This Agreement shall be construed equally as between the parties hereto, and shall not be construed against the party responsible for its drafting. Captions in this Agreement are inserted for convenience of reference only, and do not define, describe or limit the scope or intent of this Agreement or any of the terms hereof.
