(ii) "Registration Statement" means the Registration Statement filed by Purchaser with the Commission for a public offering and sale of securities of Purchaser pursuant to this Section, but shall not include a Registration Statement on Form S-8 or Form S-4, or any other registration statement filed by Purchaser with the Commission covering only securities proposed to be issued in exchange for securities or assets of another corporation. (iii) "Registerable Shares" means the shares of Purchaser Common Stock acquired by Sellers pursuant to the terms of this Agreement, and shall include any other shares of common stock of Purchaser issued in respect of such shares (whether because of stock splits, stock dividends, reclassifications, recapitalizations, or similar events affecting Purchaser); provided, however, that shares of common stock of Purchaser which are Registerable Shares shall cease to be Registerable Shares upon any sale pursuant to a Registration Statement under this Section 5, or with respect to a particular Seller, any other disposition of less than all of the shares of common stock of Purchaser received by such Seller pursuant to a private sale or other disposition, including all dispositions of the common stock by Sellers pursuant to Section 4(1) and Rule 144 of the Act, it being the expressed intentions of the parties hereto that the registration rights contained herein may only be assigned by a Seller in connection with any private sale or other transaction agreed to by such Seller subsequent to the date hereof if all of such Seller's Registerable Shares are sold or otherwise transferred pursuant to such transaction. (b) Sale or Transfer of Shares; Legend.

A COPY OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE RECORD HOLDER OF THE CERTIFICATE TO HARKEN ENERGY CORPORATION. (c) Demand Registrations. (i) Requests for Registration. At any time after the Closing, either of (x) CAB and Crusader and (y) AHI may request registration under the Securities Act of all or part of their Registerable Shares. Each request for a Demand Registration shall specify the approximate number of Registerable Shares requested to be registered and the anticipated per share price range for such offering. Within ten days after receipt of any such request, Purchaser will give written notice of such requested registration to all other holders of Registerable Shares and will include in such registration, subject to subparagraph (c) (iii), all Registerable Shares with respect to which Purchaser has received written requests for inclusion therein within 15 days after the receipt of Purchaser's notice. In the event either of (x) CAB and Crusader or (y) AHI shall request a Demand Registration pursuant to this Section 5(c), Purchaser shall provide written notice to the Seller (or Sellers) who did not request such Demand Registration, whereupon such Seller (or Sellers) shall have ten (10) days from receipt of such notice to elect in writing to have its Registrable Shares registered pursuant to such Demand Registration. The failure to elect in writing within such 10-day period shall be deemed an election to not have such Seller's (or Sellers') shares registered pursuant to such Demand Registration. If such Seller (or Sellers) elect to not have its shares registered pursuant to such Demand Registration, such Seller (or Sellers) shall have no further rights of a Demand Registration under this Section 5(c) and provided such registration otherwise counts as a Demand Registration pursuant to paragraph (c) and (g) of this Section. Any registration requested pursuant to this subparagraph (c)(i) is referred to herein as a "Demand Registration." (ii) Number of Demand Registrations. The holders of Registerable Shares will be entitled to require one Demand Registration in which Purchaser will pay all Registration Expenses (as hereinafter defined). A registration will not count as a Demand Registration unless and until it has remained effective for 180 days or such shorter period as shall be required to sell all of the securities registered pursuant thereto (but not before the expiration of the applicable prospectus delivery period); provided that in any event Purchaser will pay all - 5 - <PAGE> 6 Registration Expenses in connection with any registration initiated as a Demand Registration whether or not it has become effective. (iii) Priority on Registrations. Purchaser will not include in any Demand Registration any securities which are not Registerable Shares without the prior written consent of the holders of the Registerable Shares initially requesting such registration. If a Demand Registration is an underwritten offering and the managing underwriters advise Purchaser in writing that in their opinion the number of Registerable Shares and, if permitted hereunder, other securities requested to be included in such offering, exceeds the number of Registerable Shares and other securities, if any, which can be sold in an orderly manner in such offering within a price range acceptable to the holders of the Registerable Shares initially requesting registration, Purchaser will include in such registration, prior to the inclusion of any securities which are not Registerable Shares, the number of Registerable Shares requested to be included which in the opinion of such underwriters can be sold in an orderly manner within the price range of such offering, pro rata among the respective holders thereof on the basis of the amount of Registerable Securities requested by such holders to be included in such registration. (iv) Selection of Underwriters. If any Demand Registration is in the form of an underwritten offering, Purchaser will select and retain the investment banker or investment bankers and manager or managers that will administer the offering; provided, however, that such selection will be subject to the approval of the holders of the Registerable Shares participating in such registration, which shall not be unreasonably withheld. Purchaser shall, (together with all holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting. If a holder of Registerable Shares disapproves of the terms of the underwriting, such Person may elect to withdraw therefrom by written notice to Purchaser and the managing underwriter. The Registerable Shares so withdrawn shall also be withdrawn from registration. (v) Minimum Shares Included. Purchaser shall not be required to effect any Demand Registration unless the holders of Registerable Shares agree to include therein Registerable Securities that at the time of demand constitute at least 50% (or such lesser percentage as the underwriter shall determine is desirable) of the Registerable Securities. (d) Piggyback Registrations. (i) Right to Piggyback. Whenever Purchaser proposes to register any of its securities under the Securities Act for sale for cash (other than pursuant to a Demand Registration) and the registration form to be used may be used for the registration of Registerable Shares, Purchaser will give prompt written notice to all holders of Registerable Shares of its intention to effect such a registration and will include in such registration all Registerable Shares with respect to which Purchaser has received written requests for inclusion therein within 15 days after the receipt of Purchaser's notice (a "Piggyback Registration"). If Purchaser gives notice of such a proposed registration, the total number of Registerable Shares which shall be included in such registration shall be limited to such number, if any, as in the reasonable opinion of the - 6 - <PAGE> 7 manager of such offering would not adversely affect the marketability or offering price of all of the securities proposed to be offered by Purchaser in such offering; provided, however, if the holders of Registerable Shares having registration rights upon a Piggyback Registration are not permitted to include all of such Registerable Shares by reason of such determination by the manager of the offering, the Registerable Securities to be included in the offering shall be determined in accordance with subparagraphs (d) (iii) and (iv) below. Notwithstanding the foregoing, Purchaser may, in its sole discretion and without the consent of any holder of Registerable Shares, withdraw such Registration Statement and abandon such proposed public offering. (ii) Piggyback Expenses. The Registration Expenses of the holders of Registerable Shares will be paid by Purchaser in all Piggyback Registrations. (iii) Priority on Primary Registrations. If a Piggyback Registration is a primary registration on behalf of Purchaser, and the managing underwriters advise the company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to Purchaser, Purchaser will include in such registration (i) first, the securities Purchaser proposes to sell, (ii) second, the Registerable Shares requested to be included in such registration, pro rata among the holders thereof on the basis of the number of shares of such Registerable Shares requested to be included in such registration by each such holder, and (iii) third, other securities requested to be included in such registration. (iv) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of Purchaser's securities, and the managing underwriters advise Purchaser in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the holders initially requesting such registration, Purchaser will use its reasonable efforts to include in such registration (i) first, the securities the holders initially requesting such registration propose to sell, and (ii) second, the Registerable Shares requested to be included in such registration, pro rata among the holders thereof on the basis of the number of shares of such Registerable Shares requested to be included in such registration by each such holder. (e) Holdback Agreement. Each holder of Registerable Shares agrees not to effect any public sale or distribution (including sales pursuant to Rule 144) of any Registerable Shares, within seven days prior to and during the 60-day period beginning on the date specified in writing by Company to the holder as being the intended effective date of any underwritten Demand Registration or any underwritten Piggyback Registration in which Registerable Shares are included (except as part of such underwritten registration), unless the underwriters managing the registered public offering otherwise agree. (f) Registration Procedures. Whenever the holders of Registerable Shares have requested that any Registerable Shares be registered pursuant to this Section, Purchaser will use reasonable efforts to effect the registration and the sale of such Registerable Shares in - 7 - <PAGE> 8 accordance with the intended method of disposition thereof, and pursuant thereto Purchaser will as expeditiously as possible: (i) prepare and file with the Commission a Registration Statement on the appropriate form with respect to such Registerable Shares and use all reasonable efforts to cause such Registration Statement to become effective (provided that before filing a Registration Statement or prospectus or any amendments or supplements thereto, Purchaser will furnish to the counsel selected by the holders of the Registerable Shares covered by such Registration Statement copies of all such documents proposed to be filed, which documents will be subject to the review of such counsel); (ii) prepare and file with the Commission such amendments and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for a period of not less than 180 consecutive days or such shorter period which will terminate when Registerable Shares covered by such Registration Statement have been sold (but not before the expiration of the applicable prospectus delivery period) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof sat forth in such Registration Statement; (iii) furnish to each seller of Registerable Shares such number of copies of such Registration Statement, each amendment and supplement thereto, the prospectus included in such Registration Statement (including each preliminary prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registerable Shares owned by such seller; (iv) use its reasonable efforts to register or qualify such Registerable Shares under such other securities or blue sky laws of such jurisdictions within the United States as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registerable Shares owned by such seller (provided that Purchaser will not be required to qualify generally to do business or file any general consent to service of process in any jurisdiction where it would not otherwise be required to qualify or file but for this subparagraph); (v) notify each seller of such Registerable Shares, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such Registration Statement contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and, at the request of any such seller, Purchaser will prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registerable Shares, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; - 8 - <PAGE> 9 (vi) use its reasonable efforts to cause all such Registerable Shares to be listed on each securities exchange on which similar securities issued by Purchaser are then listed and, if not so listed, to be listed on the NASD automated quotation system and, if listed on the National Association of Securities Dealers Automated Quotation System ("NASDAQ"), use its reasonable efforts to secure designation of all such Registerable Shares covered by such Registration Statement as a NASDAQ "national market system security" within the meaning of Rule 11Aa2-1 of the Securities and Exchange Commission or, failing that, to secure NASDAQ authorization for such Registerable Shares and, without limiting the generality of the foregoing, to arrange for at least one market maker to register as such with respect to such Registerable Shares with the NASD; (vii) provide a transfer agent and registrar (which may be Purchaser) for all such Registerable Shares not later than the effective date of such Registration Statement; (viii) enter into such customary agreements (including underwriting agreements in customary form) and take all such other actions as the holders of the Registerable Shares being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registerable Shares (including, without limitation, effecting a stock split or a combination of shares); (ix) make available for inspection by any seller of Registerable Shares, any underwriter participating in any disposition pursuant to such Registration Statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records (reasonably requested), pertinent corporate documents and properties of Purchaser as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause Purchaser's officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such Registration Statement; provided, however, each seller of Registerable Shares agrees that information obtained by it as a result of such inspections which is deemed confidential shall not be used by it as the basis for any market transaction in securities of the company unless and until such information is made generally available to the public and each such seller shall cause any attorney, accountant or agent retained by such seller to keep confidential any information so deemed; (x) otherwise use reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months beginning with the first day of Purchaser's first full calendar quarter after the effective date of the Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; (xi) permit any holder of Registerable Shares, which holder, in its reasonable judgment, might be deemed to be an underwriter or a controlling person of Purchaser, to participate in the preparation of such registration or comparable statement and to comment thereon; - 9 - <PAGE> 10 (xii) in the event of the issuance of any stop order suspending the effectiveness of a Registration Statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any common stock included in such Registration Statement for sale in any jurisdiction, Purchaser will use reasonable efforts promptly to obtain the withdrawal of such order; (xiii) use reasonable efforts to cause such Registerable Shares covered by such Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registerable Shares; (xiv) use its reasonable efforts to obtain a cold comfort letter from the Purchaser's independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the holders of the Registerable Shares being sold in such registration reasonably request; and (xv) use reasonable efforts thereafter to cause the Registerable Shares to qualify as "margin stock" within the meaning of Regulations G, T and U promulgated by the Federal Reserve Board.

Sellers shall only be responsible for and pay the following fees and expenses of registration on a pro rata basis in accordance with the number of their Registerable Shares included in such registration: (i) Underwriting discounts and selling commissions attributable to the sale of Registerable Shares; and (ii) Fees and expenses of Sellers' independent legal counsel. Notwithstanding the foregoing, if a registration is withdrawn at the written request of the Sellers requesting such registration (other than as a result of information concerning the business or financial condition of Purchaser which is made known to Sellers after the date on which such registration was requested) and if Sellers elect in writing not to have such registration counted as a registration requested under subparagraph (c) of this Section, Sellers shall pay all reasonable Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration. For purposes of this Section, "Registration Expenses" shall mean all fees and expenses incident to Purchaser's performance of or compliance with this Section 5 (other than those specifically payable by Sellers pursuant to this subparagraph (g)), including, without limitation, all registration and filing fees, listing fees, fees and expenses of compliance with securities or blue sky laws, printing and engraving expenses, messenger and delivery expenses, and fees and disbursements for counsel, all independent certified public accountants, underwriters and any others retained by Purchaser. - 10 - <PAGE> 11 (h) Certain Delays.
