(b) RESERVE SHARES. Exhibit 8.03(b) attached hereto contains a list of Leases (the "Expiring Leases") covering depths above the base of the Discorbis 4 Sand in the St. Martinville Prospect Area, the primary terms of which have or will expire on or before December 31, 1998. At any time, and from time to time, from and after forty- five (45) days following the Closing Date until the close of business one hundred twenty (120) days following the Closing Date (or if such day is not a business day, the next following business day) Seller may notify Buyer that Seller has acquired new or renewal leases covering all or portions of the lands and depths covered by the Expiring Leases, providing for at least a three-year primary term and landowners' royalty interests comparable to those contained in the Expiring Leases. Such notice shall include (i) Seller's proposed form of assignment of such new or renewal leases to Harken Exploration, such assignment to be substantially in the form attached as Exhibit "B" hereto, (ii) a statement of how many net mineral acres are covered by each lease, and (iii) the abstracts, title opinions or whatever other title information Seller used in determining what interests are leased and the net mineral acres covered by each lease. Buyer shall have a period of not more than forty-five (45) days following notice and tender in which to notify Seller of Buyer's approval of title to the new or renewal leases or to make objections to title with regard to all or any part of the renewal leases included in the subject notice (the date of such notice or, if no notice is given, the date of the expiration of such forty-five-day period, is herein called the "Approval Date"). In the absence of timely notice, Buyer will be deemed to have approved title to all of the new or renewal leases. Those leases subject to Buyer's good faith title objections shall be excluded from the assignment. Upon tender of the assignment by Seller at any time subsequent to the Approval Date, Harken Energy will, at its option, either: (i) tender cash to Seller in the amount of the Remaining Purchase Price, subject to adjustment as set forth below; or (ii) deliver to Seller Reserve Shares equal in value to the Remaining Purchase Price, subject to adjustment as set forth below. The number of Reserve Shares to be delivered will be determined by dividing the Remaining Purchase Price, as adjusted, by the Average 26 <PAGE> 28 Closing Price. In the event the new or renewal leases to be assigned by Seller cover less than the number of net mineral acres set forth on Exhibit 8.03(b) attached hereto, the Remaining Purchase Price payable after the deduction, if any, required for environmental compliance under Article 6.02, shall be reduced in the proportion that the number of net mineral acres covered by the new or renewal leases bears to the number of net mineral acres set forth on Exhibit 8.03(b).

In the event that any portion of the mineral servitude estate under the Fee Tract shall revert to ownership of the surface holder, then Seller covenants for itself, its heirs and assigns forever to reconvey all such minerals that may have so reverted to Harken Energy or its nominee. If the preceding provisions of this Article 8.05 are not effective or are held to be invalid or unenforceable as against public policy, then Seller shall be deemed to have leased all of the minerals under the Fee Tract to Buyer for a term of 99 years without any royalties, or rental or other consideration deemed payable other than the Purchase Price.
