Lessee at its own expense, shall obtain prior to commencing operations on the Lands and shall thereafter maintain during the life of this Lease all Workmen's Compensation Insurance required by law and such public liability and property damage insurance, protecting both Lessee and Lessor, during each particular period of time as shall be clearly adequate in coverage and amount under the circumstances prevailing during that time period and shall annually furnish Lessor prior to the expiration of any such policy with certificates evidencing the renewals for such insurance.

Lessee shall at its sole cost and expense and without recourse against Lessor:

(a) Pay all fees and other charges payable by either Lessee or Lessor to any governmental entity or agency thereof, for or with respect to or in connection with or for the supervision of or official action with respect to the drilling, redrilling, deepening, operation or abandonment of each well on the Lands and

Lessee shall perform all reclamation and restoration of the Lands required by local, state and federal laws and regulations as a result of Lessee's activities or operations on the Lands and this obligation shall survive the termination of this Lease to the extent that any such reclamation and restoration obligations have not been completed on the date of termination.

(a) Lessee shall have the right at all times during the term of the Lease, with the consent of Lessor if requested by Lessee's lender(s), which consent shall not be unreasonably withheld, to obtain bona fide loans (including through special purpose revenue bonds) and to secure such loans by encumbering the leasehold estate created by the Lease by any permitted mortgage, deed of trust or other security instrument, including, without limitation, an assignment of Lessee's issues and profits from the Lands, which constitutes a lien on all or any portion of the leasehold estate created by the Lease ("Leasehold Mortgages"); provided however, that the proceeds of such loans are to be used for the development, design, planning, purchase, construction, maintenance, and operation of one or more power plants and associated well fields and related equipment, personal property, fixtures and improvements necessary or desirable in the operation of such facilities. It shall be unreasonable for Lessor to withhold consent to a Leasehold Mortgage if the lender is a recognized lending or financial institution (including insurance companies) that is financially sound or is the Federal government, the State of California, and/or a bona fide municipality or political subdivision of the State of California.

(b) During the continuance of each and every Leasehold Mortgage and until such time as the lien of each and every Leasehold Mortgage has been extinguished Lessor and Lessee shall cooperate in including in the Lease by suitable amendment or other instrument, from time to time, any provision which may be reasonably requested by an owner or holder of the Leasehold Mortgage ("Leasehold Lender") for the purpose of implementing mortgagee protection provisions and allowing the Leasehold Mortgage reasonable means to protect or preserve the lien of the Leasehold Mortgage on the occurrence of a default under the terms of the Lease. Lessor and Lessee each agree to execute, deliver and acknowledge any agreement necessary to effect any such amendment or other instrument; provided, however, that Lessor shall have no obligation to execute such amendment or other instrument which in any way affects the term hereto, the indemnities provided herein, or rent or royalties payable under the Lease.

Lessor shall, without charge at any time and from time to time, within ten (10) days after request by Lessee, certify to by written instrument, duly executed and acknowledged, and deliver same to Lessee or any other party or parties designated by Lessee:

(a) That the Lease is in full force and effect;
(b) Whether Lessee is in default under the Lease;
(c) That the Lease may be assigned or subleased as security to secure financing or continue same to benefit the Lease;
(d) That Lessor will afford the Leasehold Lender or any party holding a security interest in the Lease all opportunities available to Lessee to cure any defaults under the Lease;
(e) Such other reasonable assurances and information as Lessee may request.

Any notice or other communication hereunder by Lessor or Lessee to the other shall be given in writing by sending the same by prepaid registered or certified mail with return receipt requested, addressed as follow:
