5.

EXERCISE OF OPTION

5.1

Upon Fulfillment of the Option terms in the manner contemplated in paragraph 3.2 or 3.5 hereof, ISI will have exercised the Option and have earned a 50% interest in the Property.

5.2

5.3

If and when the Joint Venture is formed:

(a)

NGP shall have the right to be the operator for the purpose of conducting all further work on the Property (the "Operator"); and

(b)

the parties shall appoint a management committee (the "Management Committee"), consisting of two representatives of each party hereto and one alternate of each party hereto; and

accounting procedures, substantially in the form attached hereto as Schedule B, shall form part of the joint venture agreement and apply to the further development of the Property under the Joint Venture.

5.4

The Management Committee shall be responsible for approving programs and budgets for the programs to be conducted on the Property, and for determining the general policies and direction to be adopted by the Operator in the conduct of the future exploration and development of the geothermal potential of the Property. The Management Committee shall meet at least once annually and otherwise on 10 days notice given by the Operator and on 20 days notice given by the non-Operator. Such notices shall be accompanied by an agenda of matters to be discussed and/or decided at the meeting. Decisions of the Management Committee shall be by majority vote.

---





5.5

The Operator shall submit annual programs and budgets for exploration/development programs to the Management Committee for approval within 90 days of the expiration of the program then in effect. If the Operator should fail to submit a program of exploration/development and a budget within this time then the party acting as Operator shall immediately cease to be the Operator, and any non-operating party may not less than 60 days thereafter assume the position of Operator by proposing a program and budget for the ensuing year for consideration and approval by the Management Committee.

Failure to elect within this time will be deemed to be an election not to participate, and the interest of the non-contributing party shall be subject to dilution pursuant to paragraph 5.9.

5.7

Notwithstanding any other term hereof, for so long as NGP holds a minimum 50% interest in the Property, it shall be the Operator of the Property. If at any time after the commencement of the Joint Venture NGP should hold less than a 50% interest in the Property, or at any time an Operator of the Property is unable to act as Operator of the Property, then a new Operator shall be selected by the party who has the next largest interest in the Joint Venture.

From the date of the commencement of the Joint Venture, it is agreed that the Operator of the Property shall be entitled to receive administrative fees at the rates provided section 2.12 of the Accounting Procedures. The Management Committee shall annually review the administrative fees and shall amend the methodology or rates in a manner so as to ensure that the Operator neither makes a profit nor incurs a loss from such methodology or rates.

5.9

The interest of the contributing party shall be increased and the interest of the non-contributory party shall be decreased so that the interest of such party at all times is that percentage which is equivalent to:

(a)

the sum of the party's deemed costs and actual costs, divided by,

(b)

the sum of the total deemed costs and actual costs of all parties,

(c)

and multiplied by 100.

A party who has had its interest reduced hereunder shall only be entitled to participate in subsequent programs and budgets to the extent of its participating interest at the time any subsequent programs and budgets are approved by the Operator of the Property. In the event that a party fails to contribute to a program and budget and the contributing parry or parties do not complete at least 70% of the costs contemplated, then the non-contributory party shall be entitled, within thirty (30) days of being notified of completion of the reduced program, to pay its share of the costs actually made by the contributing party or parties and thereby maintain its interest. If the non-contributory party fails to contribute within such thirty (30) day period, its interest shall be reduced in accordance with the foregoing provisions.







---





5.10

In the event a party is diluted to a 10% or smaller interest, by the operation of paragraph 5.9 herein, then that party's interest in the Joint Venture and the Property shall automatically convert to a royalty, payable on an annual basis, on revenue generated from the Property equal to 2.5% for geothermal energy, 1% for by-products, 0.75% for electric power produced with binary technology, 0.875% for electric power produced with flash technology, and 1% for electric power produced with dry steam technology.
