Porter, Harken Energy Corporation, 5605 North MacArthur Blvd., Suite 400, Irving, Texas 75038 (Telephone: (972) 753-6900). 3 5 THE COMPANY Harken is engaged in oil and gas exploration, development and production operations both domestically and internationally through its various wholly-owned subsidiaries and joint venture investments. Harken's domestic operations include oil and gas exploration and production operations in the Four Corners Area of Utah, Arizona and New Mexico, the Gulf Coast of Texas, the Texas Panhandle, the Magnolia region of Arkansas and the Carlsbad region of New Mexico. Harken's international operations include five exclusive Colombian Association Contracts between Harken's wholly-owned subsidiary, Harken de Colombia, Ltd., and Empresa Colombiana de Petroleos, the state-owned oil company of the Republic of Colombia. Harken was incorporated in 1973 in the State of California and reincorporated in 1979 in the State of Delaware. Harken's principal offices are located at 5605 North MacArthur Blvd., Suite 400, Irving, Texas 75038 and its telephone number is (972) 753-6900. RISK FACTORS Prior to making an investment decision, prospective investors should consider carefully all of the information set forth in this Prospectus and, in particular, should evaluate the following risk factors. VOLATILITY OF HARKEN COMMON STOCK TRADING PRICE The daily closing prices of the Common Stock as reported by the American Stock Exchange has fluctuated significantly over the past 12 months, ranging from a high of $7.50 per share to a low of $3.50 per share. Management believes that the price fluctuations and trading activity in the Common Stock during the past 12 months are attributable to a number of factors, including Harken's international exploration activities. There can be no assurance that future announcements regarding Harken's international exploration efforts will not have a substantial adverse effect on the then prevailing market price of the Common Stock. LOSSES FROM CONTINUING OPERATIONS Harken reported losses from continuing operations for the fiscal years ended December 31, 1994, 1995 and 1996 in the amounts of $8,211,000, $1,625,000 and $341,000, respectively. For the first nine months of 1997, Harken reported income of approximately $152,000. There can be no assurance, however, that Harken will continue to remain profitable. POTENTIAL DILUTION; EFFECT OF SALES OF COMMON STOCK ON MARKET PRICE As of January 23, 1998, there were 121,811,534 shares of Common Stock outstanding. Harken has reserved a significant number of shares of Common Stock for future issuance as described below. There can be no assurance that the issuance of the shares of Common Stock which have been reserved for future issuance will not have a material adverse effect on the then prevailing market price of the Common Stock. Furthermore, issuance of the shares of Common Stock as described below could result in significant dilution to the stockholders of the Company. On June 11, 1997, Harken issued $70,000,000 in principal amount of its 5 1/2% Senior Convertible Notes due 2002 (the "Notes"). The Notes are convertible into shares of Common Stock by the holders thereof at a conversion price of $5.00 per share at any time after July 21, 1997. The Company has the right to force the mandatory conversion of all outstanding Notes into Common Stock at any time after June 11, 1998. As of January 12, 1998, Notes in the principal amount of $39,880,000 remained outstanding and up to 7,976,000 shares of Common Stock could be required to be issued upon conversion of such Notes. In October and December 1997, Harken entered into two separate Development Finance Agreements (the "Development Finance Agreements") with seven institutional investors (the "Investors"), pursuant to which the Investors provided funds to Harken to finance drilling of three prospects in Colombia. In exchange, the 4 6 Investors received the right to receive future payments from Harken based on Harken's net profits from the three prospects (the "Participation"). The Investors have the right, for a period of two years beginning in October 1998, to convert all or part of the Participation into shares of Common Stock. The number of shares of Common Stock to be issued upon conversion of the Participation will be equal to the quotient of (i) the Payment Amount (less any distributions made in respect of the Participation) plus an amount equal to 15% interest per annum on the net Payment Amount compounded monthly (the "Invested Amount"), divided by (ii) the market price of the Common Stock at the time of conversion. Harken also has the right to convert the Participation into shares of Common Stock with the number of shares of Common Stock to be issued to be equal to the quotient of (i) the Payment Amount (less any distribution made in respect of the Participation) plus an amount equal to 25% interest per annum on the net Payment Amount compounded monthly, divided by (ii) the market price of the Common Stock at the time of conversion. Harken can also elect to pay cash upon any conversion of the Participation in lieu of issuing shares of Common Stock. The Development Finance Agreements also require the issuance of additional shares of Common Stock in the event of a conversion to the extent that the Investors do not, under certain circumstances, realize the Invested Amount from the sale of the shares of Common Stock issued upon conversion. Harken has reserved additional shares of Common Stock for issuance as follows: (i) 2,143,937 shares of Common Stock have been reserved for issuance upon exercise of outstanding warrants; and (ii) 8,831,999 shares of Common Stock have been reserved for issuance upon exercise of outstanding stock options and stock options which may be issued pursuant to Harken's existing stock option plans. PREFERRED STOCK AUTHORIZED FOR ISSUANCE Harken has ten million shares of preferred stock available for issuance. The Board of Directors is authorized to issue such preferred stock in one or more series and to set the designations, preferences, powers and relative rights and restrictions thereof without further approval by the stockholders of the Company. Presently, Harken has four series of preferred stock authorized, but no shares of preferred stock are currently outstanding. Such shares of preferred stock, if issued, would have certain preferences over the shares of Common Stock with respect to the payment of dividends and upon liquidation, dissolution, winding-up and in certain instances, voting. The Board of Directors of Harken also may authorize additional series of preferred stock in the future that have similar or additional preferences over the shares of Common Stock. RISKS RELATED TO INTERNATIONAL OPERATIONS Harken presently conducts operations in Colombia and anticipates that it will conduct significant operations in Colombia in the future. Foreign properties, operations or investments may be adversely affected by local political and economic developments, exchange controls, currency fluctuations, royalty and tax increases, retroactive tax claims, renegotiation of contracts with governmental entities, expropriation, import and export regulations and other foreign laws or policies governing operations of foreign-based companies, as well as by laws and policies of the United States affecting foreign trade, taxation and investment. In addition, as certain of Harken's operations are governed by foreign laws, in the event of a dispute, Harken may be subject to the exclusive jurisdiction of foreign courts or may not be successful in subjecting foreign persons to the jurisdiction of courts in the United States. Harken may also be hindered or prevented from enforcing its rights with respect to a governmental instrumentality because of the doctrine of sovereign immunity. Exploration and production activities in areas outside the United States are also subject to the risks inherent in foreign operations, including loss of revenue, property and equipment as a result of hazards such as expropriation, nationalization, war, insurrection and other political risks. Harken anticipates that full development of the oil and gas reserves in the contract areas covered by Harken's five Colombian Association Contracts will take several years and may require extensive production facilities which could require significant additional capital expenditures. The ultimate amount of such expenditures cannot be presently predicted. Harken anticipates that amounts required to fund international activities, including those in Colombia, will be funded from existing cash balances, asset sales, stock issuances, production payments, operating cash flows and potentially from industry partners; however, there can be no 5 7 assurance that Harken will have adequate funds available to it to fund its international activities without participation from industry partners or that participation from industry partners can be obtained to fund such international activities. In addition, Harken faces certain deadlines for completing specific projects required pursuant to the five Colombian Association Contracts. Failure to meet any of such deadlines could result in Harken losing its rights to one or more of the Association Contracts, which could have a material adverse effect on Harken's business. UNCERTAINTIES IN UNITED STATES -- COLOMBIA RELATIONS Pursuant to the Foreign Assistance Act of 1961, the President of the United States is required to determine whether to certify that certain countries have cooperated with the United States, or taken adequate steps on their own, to achieve the goals of the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. In 1995, 1996 and 1997, the President did not certify Colombia. As a result, the United States imposed substantial economic sanctions on Colombia, including the withholding of bilateral economic assistance, the blocking of Export-Import Bank and Overseas Private Investment Corporation loans and political risk insurance, and the entry of the United States votes against multilateral assistance to Colombia in the World Bank and the InterAmerican Development Bank. It is likely that the United States will continue to not certify Colombia as long as the current Colombian government remains in power. The consequences of continued and successive United States decertifications of Colombian activities are not fully known, but may include the imposition of additional economic sanctions on Colombia in 1998 and succeeding years. The President also has authority to impose far-reaching economic, trade and investment sanctions on Colombia pursuant to the International Emergency Economic Powers Act of 1978. The Colombian government's reaction to United States sanctions could potentially include, among other things, restrictions on the repatriation of profits and the nationalization of Colombian assets owned by United States entities. Accordingly, imposition of the foregoing economic and trade sanctions on Colombia could materially affect the performance of the Common Stock and the Company's long-term financial results. INDUSTRY RISKS Oil and Gas Price Volatility. The revenues generated by Harken are highly dependent upon the prices of crude oil and natural gas. Fluctuations in the energy market make it difficult to estimate future prices of oil and natural gas. Fluctuations in energy prices are caused by a number of factors, including regional, domestic and international demand, energy legislation, federal or state taxes on sales of crude oil and natural gas, production guidelines established by the Organization of Petroleum Exporting Countries, and the relative abundance of supplies of alternative fuel such as coal. Additionally, changing international economic and political conditions may have a dramatic impact upon crude oil and natural gas prices. Many of these factors are beyond the control of Harken. Business Risks. Harken must continually acquire or explore for and develop new oil and gas reserves to replace those being depleted by production. Without successful drilling or acquisition ventures, Harken's oil and gas assets, properties and revenues derived therefrom will decline over time. To the extent Harken engages in drilling activities, such activities carry the risk that no commercially viable oil or gas production will be obtained. The cost of drilling, completing and operating wells is often uncertain. Moreover, drilling may be curtailed, delayed or canceled as a result of many factors, including shortage of available working capital, title problems, weather conditions, environmental concern, shortages of or delays in delivery of equipment, as well as the financial instability of well operators, major working interest owners and drilling and well servicing companies. The availability of a ready market for Harken's oil and gas depends on numerous factors beyond its control, including the demand for and supply of oil and gas, the proximity of Harken's natural gas reserves to pipelines, the capacity of such pipelines, fluctuation in seasonal demand, the effects of inclement weather, and government regulation. New gas wells may be shut-in for lack of a market until a gas pipeline or gathering system with available capacity is extended into the area. 6 8 Operating Hazards and Uninsured Risks. The operations of Harken are subject to the inherent risks normally associated with exploration for and production of oil and gas, including blowouts, cratering, pollution and fires, each of which could result in damage to or destruction of oil and gas wells or production facilities or damage to persons and property. As is common in the oil and gas industry, Harken is not fully insured against these risks, either because insurance is not available or because Harken has elected to self-insure due to high premium costs. The occurrence of a significant event not fully insured against could have a material adverse effect on Harken's financial condition. Environmental Regulation. Harken's domestic activities are subject to various Navajo, federal, state, and local laws and regulations covering the discharge of material into the environment or otherwise relating to protection of the environment. In particular, Harken's oil and gas exploration, development, production, its activities in connection with storage and transportation of liquid hydrocarbons and its use of facilities for treating, processing, recovering, or otherwise handling hydrocarbons and wastes therefrom are subject to stringent environmental regulation by governmental authorities. In addition to these domestic laws and regulations, Harken's international operations are subject to the laws, regulations and governmental approvals of each foreign country in which it conducts activities including, but not limited to, environmental laws and regulations governing oil and gas operations. The environmental legislation of Colombia provides for restrictions and prohibitions on spills, releases or emissions of various substances produced in association with oil operations. Under Colombia's environmental laws, the Company is required to submit a report evaluating the environmental impact of any actions proposed to be taken which might have a negative impact on the environment for approval to the Colombian Ministry of the Environment. Specifically, Harken is required to submit environmental impact reports regarding each well Harken proposes to drill, all seismic activities and any proposed pipelines or trucking activity. Failure to timely receive approval of environmental reports has in the past delayed Harken's operations and there can be no assurance that Harken will not suffer future delays. Colombia's regulatory framework with regard to environmental protection is not as fully developed and detailed as that which exists in the United States. The Company intends that its operations in Colombia will be designed to meet standard international petroleum industry practice and, as they develop, Colombian requirements. Such domestic and foreign laws and regulations have increased the costs of planning, designing, drilling, installing, operating and abandoning Harken's oil and gas wells and other facilities and may do so in the future. Imprecise Nature of Reserve Estimates. Reserve estimates are imprecise and may be expected to change as additional information becomes available. Furthermore, estimates of oil and gas reserves, of necessity, are projections based on engineering data, and there are uncertainties inherent in the interpretation of such data as well as the projection of future rates of production and the timing of development expenditures. Reserve engineering is a subjective process of estimating underground accumulations of oil and gas that cannot be measured in an exact way, and the accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Competition. The oil and gas industry is competitive in all its phases. Competition is particularly intense respecting the acquisition of desirable producing properties and the sale of oil and natural gas production. Harken's competitors in oil and gas exploration, development and production include major oil companies and numerous independent oil and gas companies, and individual producers and operators. Many of Harken's competitors possess and employ financial and personnel resources substantially greater than those which are available to Harken, and may, therefore, be able to pay greater amounts for desirable leases and to define, evaluate, bid for and purchase a greater number of producing prospects than the financial or personnel resources of Harken will permit. Extensive Regulation. The production of oil and gas is subject to extensive Navajo, federal and state laws, rules, orders and regulations governing a wide variety of matters, including the drilling and spacing of wells, allowable rates of production, prevention of waste and pollution and protection of the environment. In addition to these domestic laws and regulations, Harken's international operations are subject to the laws, regulations and governmental approvals of each foreign country in which it conducts activities including, but not limited to, environmental laws and regulations governing oil and gas operations. Such laws, rules and regulations are subject to change. Any such change in any law, rule or regulation could have the effect of 7 9 increasing the Company's cost of exploration or production or may limit the Company's revenues by regulating the level of oil and gas production, either of which could have a material adverse effect on the financial condition of the Company.

It is anticipated that the Selling Stockholders will offer the Shares in the manner set forth on the cover page of this Prospectus, from time to time, directly or through broker-dealers or underwriters who may act solely as agents or may acquire the Shares as principals, in all cases as designated by the Selling Stockholders. Such underwriters or broker- dealers acting either as principal or as agent, may receive compensation in the form of usual and customary or specifically negotiated underwriting discounts, concessions or commissions from the Selling Stockholders or the purchasers of the securities offered hereby for whom they may act as agent. The net proceeds to the Selling Stockholders from the sale of Common Stock so offered will be the purchase price of the Common Stock sold less the aggregate agents' commissions and underwriters' discounts, if any, and other expenses of issuance and distribution not borne by the Company. The Selling Stockholders and any dealers or agents that participate in the distribution of Common Stock may be deemed to be "underwriters" within the meaning of the Securities Act. At any time a particular offer of Common Stock is made, to the extent required, the specific shares of Common Stock to be sold, the purchase price, public offering price, the names of any such agent, dealer or underwriter and any applicable commission or discount with respect to a particular offering will be set forth in an accompanying Prospectus Supplement. Such Prospectus Supplement may, if necessary, be in the form of a post-effective amendment to the Registration Statement of which this Prospectus is a part, and will be filed with the Commission to reflect the disclosure of additional information with respect to the distribution of such securities.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Under Section 145 of the General Corporation Law of the State of Delaware ("Delaware Law"), a Delaware corporation may indemnify its directors, officers, employees and agents against expenses (including attorneys fees), judgments, fines and settlements in nonderivative suits, actually and reasonably incurred by them in connection with the defense of any action, suit or proceeding in which they or any of them were or are made parties or are threatened to be made parties by reason of their serving or having served in such capacity. Delaware law, however provides that such person must have acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and in the case of a criminal action, such person must have had no reasonable cause to believe his or her conduct was unlawful. Section 145 further provides that in connection with the defense or settlement of any action by or in the right of the corporation, a Delaware corporation may indemnify its directors and officers against expenses actually and reasonably incurred by them if, in connection with the matters in issue, they acted in good faith, in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made with respect to any claim, issue or matter as to which such person has been adjudged liable for negligence or misconduct unless the Court of Chancery or the court in which such action or suit is brought approves such indemnification. Section 145 further permits a Delaware corporation to grant its directors and officers additional rights of indemnification through bylaw provisions and otherwise, and to purchase indemnity insurance on behalf of its directors and officers. Indemnification is mandatory to the extent a claim, issue or matter has been successfully defended. Article Ten of the Company's Certificate of Incorporation and Article VII of the Company's bylaws provide, in general, that the Company shall indemnify its directors and officers under certain of the circumstances defined in Section 145. The Company has entered into agreements with each member of its Board of Directors pursuant to which it will advance to each director costs of litigation in accordance with the indemnification provisions of the Company's Certificate of Incorporation and bylaws.

(a) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's Annual Report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (b) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereto) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (i) and (ii) above do not apply if the registration statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs II-2 15 is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described under Item 15 above, or otherwise, the Registrant has been advised that, in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. II-3 16 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Irving, State of Texas, on February 3, 1998.
