Each Advance requested shall be made pro rata by the Investors in the proportion that the respective amounts set forth opposite their names in Annex 1 hereto bear to $3,500,000.

Owner shall use all funds from Advances to finance geological, geophysical and engineering operations and studies of the Subject Interests and the drilling, completing and equipping or abandonment of two wells and related facilities on the Subject Interests.

Section 3.6. Accounting. All debits to the Account which are attributable to costs and expenses paid by Harken Colombia during a calendar quarter up to and including the last day of such calendar quarter shall be debited against the Account as of the last day of such calendar quarter; provided that any such debits which do not (and will not) result from payments to third parties or to Harken Colombia shall be debited against the Account as of the last day of the calendar quarter in which they arise.

Investors shall participate in the Designated Percentage of the net profits derived from the Subject Interests, as provided in this Agreement, only after and while all debits properly debited against the Account shall have been offset by credits to the Account and a credit balance shall exist in the Account. Section 3.7. Payments. On or before 60 days after the end of each calendar quarter, Owner shall furnish to Investors a detailed statement clearly reflecting the condition of the Account as of the close of business on the last day of such calendar quarter, and clearly reflecting those items which gave rise to debits and credits to the Account during such quarter and clearly reflecting for the Subject Interests, the quantities of Subject Hydrocarbons produced therefrom during the quarter covered by such statement, the volumes of such production sold, the prices at which such volumes were sold, and the taxes paid with respect to such sales. Any deficit reflected by any such statement shall be carried forward for the next and succeeding months until such deficit has been wiped out and liquidated. In case a net profit is reflected by any such statement, payment to Investors of the Designated Percentage of the amount of such net profit shall be enclosed with the statement rendered to Investors (or, if requested at any time by Investors, paid by bank wire transfer to such bank and account designated in writing by Investors); provided, however, that (a) Owner may elect to cause Harken Colombia (instead of Owner) to make any payment required under this Section to Investors in U.S. dollars, (b) any payment to Investors under this Section shall be reduced by any costs or losses from currency conversions, compliance with exchange control obligations, withholding obligations and remittance and other taxes which are properly chargeable to the Account pursuant to Section 3.4(b) or (c) and (i) are incurred by Harken Colombia in connection with such payment to Investors or any payment of an amount equivalent to such payment by Harken Colombia to Owner, or (ii) in the event such payment is made by Owner from its U.S. funds without any equivalent payment by Harken Colombia to Owner, would have been so incurred if Harken Colombia had paid to Owner an amount equivalent to such payment, and (c) Owner may retain up to one-third of Investors' share of any such net profit in the event and to the extent that the debits that Owner reasonably projects will be charged to the Account during the next three months will exceed the credits that Owner reasonably projects will be made to the Account during such three-month period and apply such retained amount to the payment of Investors' share of such debits. Any such retained amount that is subsequently determined to be unnecessary for the payment of Investors' share of such debits shall be paid promptly to Investors. In the event any amount is deducted from any payment pursuant to subsections (a), (b) or (c) above, such amount shall not thereafter be charged to the Account to the extent it would cause any direct or indirect double charge to the Account or the Investors for such amount. Section 3.8. Overpayments and Underpayments. If at any time Owner inadvertently pays Investors more or less than the amount then due with respect to the Rio Negro NPI, the amount or amounts otherwise payable for any subsequent period or periods shall be reduced or increased by such overpayment or underpayment, plus an amount equal to interest (computed at the Agreed 11 <PAGE> 12 Rate) on the unrecovered balance of such overpayment or underpayment during the period of such overpayment or underpayment. Section 3.9. Prudent Operator Standard. Harken Colombia (subject to the terms and provisions of the Association Contract and any applicable operating agreements) shall have exclusive charge, management and control of all operations to be conducted on the Subject Interests and may take any and all actions which a reasonably prudent operator would deem necessary or advisable in the management, operation and control thereof. Owner shall cause Harken Colombia to operate and maintain the Subject Interests as would a prudent operator under similar circumstances in accordance with good oil field practices. Owner shall cause Harken Colombia to promptly (and, unless the same are being contested in good faith and by appropriate proceedings before the same are delinquent) pay or cause to be paid all costs and expenses (including without limitation all taxes and all costs, expenses and liabilities for labor, materials and equipment incurred in connection with the Subject Interests and all obligations to the holders of interests affecting the Subject Interests) incurred from and after the Effective Date in developing, operating and maintaining the Subject Interests. As to those of the Subject Interests as to which Harken Colombia hereafter may not be the operator, Owner shall cause Harken Colombia to take all such action and exercise all such rights and remedies as are reasonably available to Harken Colombia to cause the operator to so maintain and operate such Subject Interests (provided that Harken Colombia shall never be obligated to pay any costs or expenses attributable to any interest other than the Subject Interests and all royalties related thereto). Section 3.10. Sales of Subject Hydrocarbons. Owner shall have the obligation to cause Harken Colombia to market or cause to be marketed, subject to the terms of the Association Contract, the Subject Hydrocarbons in accordance with reasonable and prudent business judgment and sound oil field practices and on such terms and conditions as Harken Colombia shall determine to be in the best interests of Investors; provided, however, that all such sales of Subject Hydrocarbons (a) shall be upon terms and conditions which are the best terms and conditions available as determined in good faith by Harken Colombia taking into account all relevant circumstances, including without limitation, price, quality of production, access to markets or lack thereof, minimum purchase guarantees, identity of purchaser and length of commitment, (b) shall be on terms and conditions at least as favorable as Harken Colombia obtains for oil, gas and/or minerals not subject to this Agreement which are of comparable type and quality and in the same or similar location, except where such terms and conditions cannot be made available to sales of the Subject Hydrocarbons under pre-existing contracts, and (c) shall be made to Non-Affiliates of Owner or Harken Colombia except that sales of Subject Hydrocarbons may be made to an Affiliate of Owner or Harken Colombia that is owned in part by a Governmental Authority and that owns or operates a pipeline or other Processing facility if the price paid by such Affiliate is no less favorable than the prices then being paid by a Non-Affiliate for oil, gas and/or minerals which are of comparable type and quality and in the same or similar locations. Section 3.11. Insurance. Owner shall cause Harken Colombia to obtain or cause to be obtained (and maintain or cause to be maintained during the economic life of the Subject Interests) 12 <PAGE> 13 insurance coverage in such amounts, with provisions for such deductible amounts and for such purposes as Harken Colombia shall determine to be appropriate (and, because of cost, availability and other factors, Harken Colombia may determine not to acquire any such insurance). Section 3.12. Contracts with Affiliates. Except as provided otherwise in the Association Contract or any applicable operating agreement, Owner, Harken Colombia and/or their Affiliates may perform services and furnish supplies and equipment with respect to the Subject Interests, provided that the amount of compensation, price or rental that can be charged to the Account therefor must be no less favorable than those available from Non-Affiliates in the area engaged in the business of rendering comparable services or selling or leasing comparable equipment and supplies which could reasonably be made available to the Subject Interests. Section 3.13. Government Regulation. All obligations of Owner and/or Harken Colombia hereunder shall be subject to and limited by (i) all applicable Laws and (ii) the Association Contract as it may be modified, amended and/or supplemented from time to time. Where the price at which Subject Hydrocarbons are sold is limited by applicable Laws, the price so permitted to be paid for Subject Hydrocarbons shall be controlling if lower than prices established in Production Sales Contracts or required hereunder. Section 3.14. Abandonments. After the Commitment Period, Harken Colombia shall have the right without the consent of Investors to release, surrender and/or abandon its interest in the Subject Interests and/or the Association Contract, or any part thereof, or interest therein, even though the effect of such release, surrender or abandonment may be to affect adversely the Rio Negro NPI; provided, however, that (a) Investors' interest in the Rio Negro NPI shall automatically be converted into Preferred Shares pursuant to Article VI if, within two years after the expiration of the Commitment Period, Harken Colombia has released, surrendered and/or abandoned any portion of its interest in the Subject Interests and/or the Association Contract other than that required to be released, surrendered and/or abandoned for Harken Colombia to comply with the terms and conditions of the Association Contract and if Article VI shall otherwise then be applicable and (b) during the Commitment Period, Harken Colombia shall have the right without the consent of Investors to release, surrender and/or abandon that portion of the Subject Interests as shall be necessary for Harken Colombia to comply with the terms and conditions of the Association Contract. Section 3.15. Pooling and Unitization. Without the prior written consent of Investors, Harken Colombia shall have the right and power to unitize, pool or combine the lands covered by the Subject Interests, or any portion or portions thereof, as to oil, gas and/or other minerals, with any other land or contract or contracts so as to create one or more unitized areas (or, with respect to unitized or pooled areas theretofore created, to dissolve the same or to amend and/or reconfigure the same to include additional acreage or substances or to exclude acreage or substances); provided, however, that Owner shall not permit Harken Colombia to unitize, pool or combine the lands covered by the Subject Interests, or any portion or portions thereof, if the effect thereof is to benefit Harken Colombia or any of its Affiliates to the detriment of the 13 <PAGE> 14 Investors. If any of the Subject Interests are pooled or unitized in any manner, the Rio Negro NPI insofar as it affects such Subject Interest shall be considered to be pooled and unitized, and in any such event the Rio Negro NPI shall apply to (and the term "Subject Hydrocarbons" shall include) the production which accrues to such Subject Interest under and by virtue of such pooling and unitization arrangements and the Account shall be computed giving consideration to such production and costs, expenses, charges and credits attributable to such Subject Interest. Section 3.16. Non-consent Operations. (a) If Harken Colombia elects to be a non-participating party (whether pursuant to the Association Contract or an operating agreement or other agreement or requirement) with respect to any drilling, deepening, plugging back, reworking, sidetracking or completion (or other) operation on any Subject Interest or elects to be an abandoning party with respect to a well located on any Subject Interest, the consequence of which election is that Harken Colombia's interest in such Subject Interest or part thereof is temporarily (i.e., during a recoupment period) or permanently forfeited to the parties participating in such operations, or electing not to abandon such well, then the costs and proceeds attributable to such forfeited interest shall not, for the period of such forfeiture (which may be a continuous and permanent period), be debited or credited to the Account and such forfeited interest shall not, for the period of such forfeiture, be subject to the Rio Negro NPI. (b) If Harken Colombia elects to be a participating party to such a drilling, deepening, plugging back, reworking, sidetracking or completing (or other) operation, or elects to be a non-abandoning party with respect to such a well, and any other party or parties have elected not to participate in such operation (or have elected to abandon such well) with the result that (pursuant to the Association Contract or an operating agreement or other agreement or requirement) Harken Colombia becomes entitled to receive, either temporarily (i.e., through a period of recoupment) or permanently, interests belonging to such other party or parties, the costs and proceeds attributable to such non-participating parties' interests to which Harken Colombia becomes so entitled shall not be debited and credited to the Account and instead shall be for the account of Harken Colombia.

The foregoing indemnifications shall extend to Investors and their successors and assigns, all their respective affiliates and all their respective officers, directors, agents, attorneys and employees. THE FOREGOING INDEMNITIES SHALL APPLY WHETHER OR NOT ARISING OUT OF THE SOLE, JOINT OR CONCURRENT NEGLIGENCE, FAULT OR STRICT LIABILITY OF INVESTORS OR ANY OTHER PERSON OR ENTITY INDEMNIFIED HEREUNDER AND SHALL APPLY, WITHOUT LIMITATION, TO ANY LIABILITY IMPOSED UPON ANY PERSON INDEMNIFIED HEREUNDER AS A RESULT OF ANY STATUTE, RULE, REGULATION, THEORY OF STRICT LIABILITY OR OTHERWISE. Section 3.18. Assignment by Harken Colombia or Owner. (a) Without the prior written consent of Investors (which consent shall not be unreasonably withheld), Harken Colombia shall not assign, sell, transfer, convey, mortgage or pledge the Association Contract or the Subject Interests; provided, however, that Harken Colombia shall be permitted (i) to assign or otherwise transfer all or part of its interest in the Association Contract and the Subject Interests to an Affiliate of Owner for so long as such assignee shall remain an Affiliate of Owner and provided that Owner shall remain personally obligated for its duties and obligations hereunder, and (ii) to assign, sell, transfer, convey, mortgage or pledge at any time to any person a portion of Harken Colombia's interest in the Association Contract and the Subject Interests if after any such assignment, sale, transfer, conveyance, mortgage or pledge the product of (A) the percentage interest in the Association Contract and the Subject Interests which would then be owned by Harken Colombia and not mortgaged or pledged, multiplied by (B) the percentage of the outstanding shares of capital stock of Harken Colombia that is then owned by Owner and is not mortgaged or pledged, shall equal or exceed the sum of the total Designated Percentage of all Investors at the time in effect plus 10%, and provided that Harken Colombia shall remain the operator of record of the Subject Interests.
