[BIOSANTE LOGO] 175 OLDE HALF DAY ROAD LINCOLNSHIRE, ILLINOIS 60069 ---------------------------- PROXY STATEMENT FOR ANNUAL AND SPECIAL MEETING OF SHAREHOLDERS JUNE 13, 2001 ---------------------------- INFORMATION CONCERNING THE ANNUAL AND SPECIAL MEETING DATE, TIME, PLACE AND PURPOSES The meeting will be held on Wednesday, June 13, 2001, at 1:00 p.m., local time, at the American Airlines Admirals Club, Terminal 3, O'Hare International Airport, Chicago, Illinois, for the purposes set forth in the Notice of Meeting. SHAREHOLDERS ENTITLED TO VOTE Shareholders of record at the close of business on April 23, 2001 will be entitled to vote at the meeting. As of that date, there were 62,202,943 shares of our common stock and 4,687,684 shares of our class C stock outstanding. Each share of our common stock and class C stock is entitled to one vote on each matter to be voted on at the Annual and Special Meeting. Shareholders are not entitled to cumulate voting rights. PROXIES This proxy statement is being mailed to our shareholders beginning on or about May 11, 2001 in connection with the solicitation of proxies by the Board of Directors for use at the Annual and Special Meeting of Shareholders. Your vote is important. A proxy card is enclosed for your use. YOU ARE SOLICITED ON BEHALF OF THE BOARD OF DIRECTORS, TO MARK, SIGN, DATE AND RETURN THE PROXY CARD IN THE ACCOMPANYING ENVELOPE. No postage is required if mailed within the United States or from Canada. Proxies will be voted as specified by you. Signed proxies that lack any specification will be voted in favor of all of the proposals set forth in the Notice of Meeting and in favor of the election of all of the nominees for director listed in this proxy statement. THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE APPROVAL OF ALL OF THE PROPOSALS SET FORTH IN THE NOTICE OF MEETING AND FOR ALL OF THE NOMINEES FOR DIRECTOR LISTED IN THIS PROXY STATEMENT. REVOCATION OF PROXIES Any shareholder giving a proxy may revoke it at any time prior to its use at the Annual and Special Meeting by: o giving written notice of your revocation to our Secretary, o filing a duly executed proxy bearing a later date with our Secretary, or o appearing at the Annual and Special Meeting and filing written notice of revocation with our Secretary prior to use of the proxy.

QUORUM REQUIREMENT The presence at the Annual and Special Meeting, in person or by proxy, of two record holders of each of our outstanding common stock and class C stock at the Annual and Special Meeting will constitute a quorum for the transaction of business at the Annual and Special Meeting. VOTE REQUIRED Assuming a quorum is represented at the Annual and Special Meeting, either in person or by proxy, the election of the nine nominees for director requires the affirmative vote of a plurality of the shares of common stock and class C stock, voting together as a single class, present and entitled to vote in person or by proxy, and the approval of the other proposals described in this proxy statement, require the affirmative vote of the holders of a majority of the shares of common stock and class C stock, voting together as a single class, present and entitled to vote in person or by proxy. Shares represented by a proxy card including any broker non-votes on a matter will be treated as shares not entitled to vote on that matter, and thus will not be counted in determining whether that matter has been approved. A "broker non-vote" is a card returned by a broker on behalf of its beneficial owner customer that is not voted on a particular matter because voting instructions have not been received, and the broker has no discretionary authority to vote. Shares represented by a proxy card voted as abstaining on any of the proposals will be treated as shares present and entitled to vote that were not cast in favor of a particular matter, and thus will be counted as votes against that matter. Signed proxies that lack any specification will be voted in favor of all of the proposals set forth in the Notice of Meeting and in favor of the election of all of the nine nominees for directors listed in this proxy statement. PROXY SOLICITATION COSTS The cost of soliciting proxies, including the preparation, assembly and mailing of proxies and soliciting material, as well as the cost of forwarding this material to the beneficial owners of our capital stock will be borne by us. Our directors, officers and regular employees may, without compensation other than their regular compensation, solicit proxies by telephone, facsimile, telegraph or personal conversation. We may reimburse brokerage firms and others for expenses in forwarding proxy materials to the beneficial owners of our capital stock. 2

DIRECTOR COMPENSATION We do not pay fees to our directors. We do, however, periodically compensate our directors through the granting of stock options. On January 1, 2001, we granted stock options to purchase 25,000 shares of common stock to each of our non-employee directors. These options have an exercise price of $0.67 per share, fully vest on January 1, 2002 and expire ten years from the date of grant. 8

REIMBURSEMENT OF EXPENSES. All directors are reimbursed for travel expenses for attending meetings of the Board of Directors and any Board committees.

CHANGE IN CONTROL ARRANGEMENTS Our 1998 Stock Option Plan contains provisions under which the options granted under that plan would become fully exercisable following certain changes in control of our company, such as: 11

o the sale, lease, exchange or other transfer of all or substantially all of the assets of our company to a corporation that is not controlled by us; o the approval by our shareholders of any plan or proposal for the liquidation or dissolution of our company; o certain merger or business combination transactions; o more than 50% of our outstanding voting shares are acquired by any person or group of persons who did not own any shares of common stock on the effective date of the plan; and o certain changes in the composition of our Board of Directors. RELATED PARTY RELATIONSHIPS AND TRANSACTIONS --------------------------- DIRECTOR RELATIONSHIPS Messrs. Morgenstern, Holubow and Mangano were elected to our Board of Directors in July 1999 as representatives of the lead investors in the May 1999 private placement. We refer you to the discussion under the heading "May 1999 Private Placement" below. Angela Ho, a director of our company, owns approximately 2.6% of our outstanding voting securities and was elected to our Board of Directors as a representative of our several investors located in Hong Kong. Ms. Ho has not entered into any voting agreements with these Hong Kong investors nor does she otherwise have any control over the voting of shares held by these investors. Mr. Kjaer was elected to our Board of Directors as a representative of our Hong Kong investors in July 1999. Mr. Kjaer has not entered into any voting agreements with these Hong Kong investors nor does he otherwise have any control over the voting of shares held by these investors. MAY 1999 PRIVATE PLACEMENT In connection with our May 1999 private placement, we entered into a Shareholders' Agreement with the investors, which included Stephen M. Simes, Victor Morgenstern, an affiliated trust and a partnership, Fred Holubow, JO & Co., of which Ross Mangano is President, and certain of our major investors located in Hong Kong, including Hans Michael Jebsen, Marcus Jebsen and King Cho Fung. This agreement contains, among other things, a voting agreement with respect to the election of directors. APRIL 2001 PRIVATE PLACEMENT In connection with our April 2001 private placement, we sold an aggregate of 9,250,000 shares of our common stock and warrants to purchase an aggregate of 4,625,000 shares of our common stock for $0.40 per unit, each unit consisting of one share of common stock and a warrant to purchase 0.50 shares of our common stock, for an aggregate purchase price of $3,700,000, to accredited investors, including existing shareholders, directors and officers. 12

PROPOSAL TO AMEND OUR 1998 STOCK OPTION PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK RESERVED FOR ISSUANCE (PROPOSAL 2) ------------ PROPOSED AMENDMENT On December 8, 1998, the Board of Directors adopted our 1998 Stock Option Plan, and on July 13, 1999 our shareholders approved the option plan. This option plan provides for the grant to employees, officers, directors, consultants and independent contractors of our company of options to purchase shares of common stock that qualify as "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, as well as non-statutory options that do not qualify as incentive stock options. This plan is administered by the Compensation Committee of our Board of Directors, which determines the persons who are to receive awards, as well as the type, terms and number of shares subject to each award. On March 15, 2001, the Board of Directors amended the option plan, subject to shareholder approval, to increase the number of shares of common stock reserved for issuance under the option plan by 1,500,000 shares, from 7,000,000 shares to 8,500,000 shares. You are being asked to approve this amendment at the Annual and Special Meeting. PURPOSE OF THE AMENDMENT Providing stock option grants under our option plan is an important element in our overall success. In general, the Board of Directors believes that equity-based incentives align the interests of our management and employees with those of our shareholders. In addition, providing stock option grants under the option plan is an important strategy for attracting and retaining the type of high-quality executives, employees and advisors our Board of Directors believes is necessary for the achievement of our goals. Given the intense competition for such personnel, the Board of Directors believes that its ability to offer competitive compensation packages, including those with equity-based incentive components, is particularly important in attracting and retaining qualified candidates. SUMMARY OF THE 1998 STOCK OPTION PLAN A general description of the basic features of our option plan is outlined below. Unless otherwise indicated, the following summary of the principal provisions of the plan assumes the approval of the proposed amendment increasing the number of shares of common stock reserved for issuance. This summary is qualified in its entirety by reference to the actual text of the option plan, a copy of which you may obtain from us at the address set forth at the beginning of this proxy statement. PURPOSE OF THE PLAN. The option plan's purpose is to advance our interests and the interests of our shareholders by enabling us to attract and retain talented persons by providing an incentive to these individuals through equity participation in BioSante and also rewarding individuals who contribute to the achievement of our economic objectives. ELIGIBLE PARTICIPANTS. All employees of BioSante and any non-employee directors, consultants and independent contractors of BioSante who, in the judgment of the Compensation Committee, have contributed, are contributing or are expected to contribute to the achievement of our economic objectives are eligible to participate in the option plan. On April 15, 2001, approximately 15 individuals were eligible to receive options under the option plan. 13

Participants may be granted one or more options. The options will always be subject to whatever terms and conditions the Compensation Committee determines, provided such terms and conditions are consistent with the option plan. All options are deemed granted as of the date specified in the Compensation Committee's resolution, which will be the date of the participant's option agreement. Pursuant to the rules of the Canadian Venture Exchange, the number of shares reserved for issuance to any one person, pursuant to option grants, must not exceed 5% of the number of shares of common stock outstanding on a non-diluted basis. ADMINISTRATION. The Compensation Committee of the Board of Directors administers the option plan. The Compensation Committee has the authority to determine all provisions of options as long as they are consistent with the terms of the option plan. The Compensation Committee also has the authority to amend or modify the terms of any outstanding options in any manner. Any amendment or modification, however, must be permitted by the option plan and may not adversely affect any participant's rights without his or her consent. Each determination, interpretation or other action of the Compensation Committee will be conclusive and binding for all purposes on all persons. STOCK SUBJECT TO THE OPTION PLAN. The amendment to the option plan proposed hereby would increase the number of shares specifically reserved for issuance under the option plan from 7,000,000 to 8,500,000 shares. As of April 15, 2001, no shares of common stock had been issued upon the exercise of options granted under the option plan, and options to purchase 6,944,657 shares of common stock were outstanding. Accordingly, 55,343 shares remained available for future grant under the option plan as of that date. Assuming approval of an increase of 1,500,000 shares to the option plan, 1,555,343 shares would be available for future grants. The following points describe how our Compensation Committee determines the number of shares of common stock available for issuance under our option plan at any point in time. o OUTSTANDING OPTIONS -- reduces the maximum number of shares available for issuance. o SHARES ISSUED UPON EXERCISE OF OUTSTANDING OPTIONS -- reduces the maximum number of shares available for issuance. o OPTION TERMINATES UNEXERCISED OR UNVESTED -- shares become available again for issuance. o We pay for the options, in cash, not common stock -- shares become available again for issuance. In the event of any reorganization, merger, recapitalization, stock dividend, stock split or similar change in our corporate structure or our shares, appropriate adjustments will be made to the number and kind of shares reserved under the plan and under outstanding options and to the exercise price of outstanding options. OPTIONS. An option provides the optionee with the opportunity to purchase a specified number of shares of common stock at a predetermined price for a specific period of time. Incentive options must be granted with an exercise price equal to at least the fair market value of the common stock on the date of grant. Non-qualified options must be granted with an exercise price equal to at least 85% of the fair market value of the common stock on the date of grant. For purposes of the plan, the fair market value of the common stock is the closing price as reported by the Canadian Venture Exchange. On April 15, 2001, the closing sale price of a share of our common stock on the Canadian Venture Exchange was $0.40. Options will become exercisable at such times and in such installments as may be determined by the Compensation Committee, provided that options may not be exercisable after 10 years from their date of grant. 14

The exercise price of options must be paid in cash, except that the Compensation Committee may allow payment to be made (in whole or in part) by tender of a "broker exercise notice" (pursuant to which the broker or dealer is instructed to sell enough shares or loan the optionee enough money to pay the exercise price and to remit such sums to us), a promissory note, a transfer of shares of common stock (either previously owned by the participant or to be acquired upon option exercise), or by a combination of such methods. The aggregate fair market value of shares of common stock with respect to which incentive stock options may become exercisable for the first time by a participant in any calendar year may not exceed $100,000. Any incentive options in excess of this amount will be treated as non-statutory options. EFFECT OF CHANGE IN CONTROL. We refer you to "Executive Compensation and Other Benefits -- Change in Control Arrangements" for discussion regarding the effects of a "change in control" on options granted under the option plan. EFFECT OF TERMINATION OF EMPLOYMENT ON SERVICE. If a participant's employment or other service with BioSante terminates by reason of death or disability, all outstanding options will remain exercisable to the extent then exercisable for a period of six months after termination, but in no event after their original expiration date. If a participant's employment or other service with BioSante is terminated by reason of retirement, all outstanding options will remain exercisable to the extent then exercisable for a period of three months after termination, but in no event after their original expiration date. If a participant's employment or other service with us is terminated for any other reason, other than for cause, all outstanding options will remain exercisable to the extent then exercisable for a period of three months after termination. If a participant's employment or other service with us is terminated for cause, all outstanding options will immediately terminate without notice. The Board of Directors may, in our discretion, modify these post-termination provisions, provided that no option may remain exercisable beyond its expiration date. AMENDMENT OF OPTION PLAN. The Board of Directors may suspend or terminate the option plan or any portion thereof at any time, and may amend the option plan from time to time to conform the plan to any change in applicable laws or regulations or in any other respect the Board of Directors may deem to be in the best interests of BioSante. The Board of Directors may not, however, make an amendment to the option plan without shareholder approval if shareholder approval is required under Rule 16(b)(3) under the Securities Exchange Act of 1934, Section 422 of the Internal Revenue Code or the rules of any exchange of Nasdaq or similar regulatory body. Furthermore, the Board of Directors cannot make any modification to the option plan that would adversely affect outstanding options without the consent of the affected participants. TERMINATION. The option plan will terminate at midnight on December 8, 2008, unless terminated earlier by the Board of Directors. No options may be granted after such termination. Options outstanding upon termination of the option plan may continue to be exercised according to their terms. FEDERAL INCOME TAX CONSEQUENCES The following description of federal income tax consequences is based on current statutes, regulations and interpretations. The description does not include foreign, state or local income tax consequences. In addition, the description is not intended to address specific tax consequences applicable to directors, executive officers or greater than 10% shareholders of BioSante or to any individual participant who receives an option under the option plan. INCENTIVE STOCK OPTIONS. There will not be any federal income tax consequences to either the participant or BioSante as a result of the grant to an employee of an incentive stock option under the option plan. The exercise by a participant of 15

an incentive stock option also will not result in any federal income tax consequences to BioSante or the participant, except that: o an amount equal to the excess of the fair market value of the shares acquired upon exercise of the incentive stock option, determined at the time of exercise, over the amount paid for the shares by the participant will be includable in the participant's alternative minimum taxable income for purposes of the alternative minimum tax, and o the participant may be subject to an additional excise tax if any amounts are treated as excess parachute payments, as discussed below. Special rules will apply if previously acquired shares of common stock are permitted to be tendered in payment of an option exercise price. When a participant disposes of shares acquired upon exercise of an incentive stock option, the federal income tax consequences will depend upon how long the participant held those shares. If the participant does not dispose of the shares within two years after the incentive stock option was granted, nor within one year after the participant exercised the incentive stock option, then the participant will recognize a long-term capital gain or loss. The amount of the long-term capital gain or loss will be equal to the difference between: o the amount the participant realized on disposition of the shares, and o the option price at which the participant acquired the shares. We are not entitled to any compensation expense deduction under these circumstances. If the participant does not satisfy both of the above holding period requirements, then the participant will be required to report as ordinary income, in the year the participant disposes of the shares, the amount by which the lesser of: o the fair market value of the shares at the time of exercise of the incentive stock option, or o the amount realized on the disposition of the shares, exceeds the option price for the shares. We will be entitled to a compensation expense deduction in an amount equal to the ordinary income includable in the taxable income of the participant. This compensation income may be subject to withholding. The remainder of the gain recognized on the disposition, if any, or any loss recognized on the disposition, will be treated as long-term or short-term capital gain or loss, depending on the holding period. NON-STATUTORY STOCK OPTIONS. Neither the participant nor BioSante incurs any federal income tax consequences as a result of the grant of a non-statutory stock option. Upon exercise of a non-statutory stock option, a participant will recognize ordinary income, subject to withholding, on the date of exercise in an amount equal to the difference between: o the fair market value of the shares purchased, determined on the date of exercise, and o the consideration paid for the shares. The participant may be subject to an additional excise tax if any amounts are treated as excess parachute payments (see explanation below). Special rules will apply if previously acquired shares of common stock are permitted to be tendered in payment of an option exercise price. At the time of a subsequent sale or disposition of any shares of common stock obtained upon exercise of a non-statutory stock option, any gain or loss will be treated as long-term or short-term capital gain or loss, depending on the holding period from the date of exercise. In general, we will be entitled to a compensation expense deduction in connection with the exercise of a non-statutory stock option for any amounts includable in the taxable income of the participant as ordinary income, provided we 16

comply with any applicable withholding requirements. EXCISE TAX ON PARACHUTE PAYMENTS. The Internal Revenue Code also imposes a 20% excise tax on the recipient of "excess parachute payments," as defined in the Internal Revenue Code and denies tax deductibility to us on excess parachute payments. Generally, parachute payments are payments in the nature of compensation to employees of a company who are officers, shareholders or highly compensated individuals, which payments are contingent upon a change in ownership or effective control of the company, or in the ownership of a substantial portion of the assets of the company. For example, acceleration of the exercisability of options or the vesting of restricted stock awards upon a change in control of BioSante may constitute parachute payments, and in certain cases, "excess parachute payments." SECTION 162(M). Under Section 162(m) of the Internal Revenue Code, the deductibility of certain compensation paid to the chief executive officer and each of the four other most highly compensated executives of a publicly held corporation is limited to $1,000,000. Compensation for this purpose generally includes any items of compensation expense described above in connection with incentive awards under the option plan. However, certain types of compensation are excepted from this limit, including compensation that qualifies as "performance-based compensation." Under Section 162(m), any compensation expense resulting from the exercise of options under the option plan with exercise prices equal to (or greater than) the fair market value of the common stock on the date of grant should qualify as "performance-based compensation" excepted from the limit of Section 162(m). However, compensation expense in connection with any other incentive awards under the option plan will be subject to this limit. OPTIONS UNDER THE OPTION PLAN The table below summarizes outstanding options under our option plan as of April 15, 2001. The options granted in fiscal 2000 to the named executive officers are also disclosed in the Summary of Compensation Table on page 10 and the Option Grants in Last Fiscal Year beginning on page 10, as required by the rules of the Securities and Exchange Commission.

PROPOSAL TO REINCORPORATE IN DELAWARE (PROPOSAL 3) --------------------- INTRODUCTION At the Annual and Special Meeting, you will be asked to consider and act upon a proposal to approve the reincorporation of the company from Wyoming to Delaware. The Board of Directors has unanimously approved and recommends for shareholder approval the proposal. In preparation for the submission of this proposal to our shareholders, we have formed a wholly-owned Delaware subsidiary named BioSante Pharmaceuticals, Inc., which we refer to as "BioSante Delaware" in this proxy statement. We will use the term "BioSante Wyoming" to refer to our existing Wyoming corporation. If approved by our shareholders, the reincorporation will be effected by a merger transaction in which BioSante Wyoming will be merged with and into BioSante Delaware. In the merger, each issued and outstanding share of BioSante Delaware (all of which are owned by BioSante Wyoming ) will be retired and canceled and each issued and outstanding share of common stock and class C stock of BioSante Wyoming will be automatically converted into and become one share of common stock or class C stock, as the case may be, of BioSante Delaware. Upon completion of the merger, BioSante Wyoming , as a corporate entity, will cease to exist, and BioSante Delaware will continue to operate the business of the company under its current name, BioSante Pharmaceuticals, Inc. Each share certificate representing issued and outstanding shares of common stock and class C stock of BioSante Wyoming will represent the number of shares of common stock and class C stock of BioSante Delaware. IT WILL NOT BE NECESSARY FOR SHAREHOLDERS TO EXCHANGE THEIR EXISTING STOCK CERTIFICATES FOR STOCK CERTIFICATES OF BIOSANTE DELAWARE. A copy of the Agreement and Plan of Merger, which we refer to as the "merger agreement" in this proxy statement, is attached to this proxy statement as Appendix B. We are currently governed by the Wyoming Business Corporation Act and our current articles of incorporation and bylaws. If the reincorporation is approved, we will be governed by the Delaware General Corporation Law and by a new certificate of incorporation and bylaws, which will result in certain changes in the rights of our shareholders as discussed below. Copies of the certificate of incorporation and bylaws of BioSante Delaware are attached to this proxy statement as Appendices C and D, respectively. The reincorporation of BioSante in Delaware will allow us to take advantage of certain provisions of the corporate laws of Delaware. The purposes and effects of the proposed transaction are summarized below. The following is a summary of the reincorporation. Because it is a summary, it does not include all of the information regarding the reincorporation and is therefore qualified in its entirety by reference to the merger agreement, the certificate of incorporation of BioSante Delaware and the bylaws of BioSante Delaware attached to this proxy statement as Appendices B, C and D, respectively. TREATMENT OF STOCK OPTIONS AND WARRANTS Each option and warrant to purchase shares of common stock of BioSante Wyoming outstanding immediately prior to the effective time of the reincorporation will, by virtue of the reincorporation and without any action on the part of the holder thereof, be converted into and become an option or warrant to purchase, upon the same terms and conditions, the number of shares of BioSante Delaware common stock. The exercise price per share under each of the options and warrants will be equal to the 18

exercise price per share thereunder immediately prior to the effective time. DIRECTORS AND OFFICERS The directors and officers of BioSante Wyoming will be the directors and officers of BioSante Delaware after the reincorporation. EFFECTIVE TIME OF REINCORPORATION Subject to the terms and conditions of the merger agreement, we intend to file, as soon as practicable after the adoption and approval of the merger agreement by our shareholders, appropriate articles or certificates of merger with the Secretary of State of Wyoming and the Secretary of State of Delaware. The reincorporation shall become effective at the time the last of such filings is completed. It is presently contemplated that such filings will be made in late June 2001. However, the merger agreement provides that the merger may be abandoned by the Board of Directors prior to the effective time either before or after shareholder approval. In addition, the merger agreement may be amended prior to the effective time, either before or after shareholder approval. The merger agreement, however, may not be amended after shareholder approval if the amendment would, in the judgment of the Board of Directors, have a material adverse effect on your rights as shareholders or in any manner violate applicable law. EXCHANGE OF STOCK CERTIFICATES On or after the effective time of the reincorporation, all of the outstanding certificates that, prior to that time, represented shares of common stock or class C stock of BioSante Wyoming will be deemed for all purposes to evidence ownership and to represent the number of shares of the common stock or class C stock, as the case may be, of BioSante Delaware into which such shares are converted in the reincorporation (other than shares as to which the holder thereof has properly exercised dissenters' rights under Wyoming law). The registered owner of any such outstanding stock certificate will, until such certificate will have been surrendered for transfer or conversion or otherwise accounted for to BioSante Delaware, have and be entitled to exercise any voting and other rights with respect to, and to receive any dividend or other distributions upon, the shares of common stock or class C stock, as the case may be, of BioSante Delaware evidenced by such outstanding certificate. After the effective time of the reincorporation, whenever certificates which formerly represented shares of BioSante Wyoming are presented for transfer or conversion, BioSante Delaware will cause to be issued in respect thereof a certificate or certificates representing the appropriate number of shares of common stock or class C stock, as the case may be, of BioSante Delaware. YOU ARE NOT REQUIRED TO EXCHANGE YOUR STOCK CERTIFICATES FOR BIOSANTE DELAWARE STOCK CERTIFICATES, ALTHOUGH YOU MAY DO SO IF YOU WISH. PRINCIPAL REASONS FOR CHANGING OUR STATE OF INCORPORATION The Board of Directors believes that the reincorporation of our company under the laws of the State of Delaware will provide flexibility for both our management and business. For many years Delaware has followed a policy of encouraging incorporation in Delaware and, in furtherance of that policy, has adopted comprehensive, modern and flexible corporate laws that are periodically updated and revised to meet changing business needs. As a result, many major corporations have initially chosen Delaware for their domicile or have subsequently reincorporated in Delaware in a manner similar to what we have proposed. Because of Delaware's significance as the state of incorporation for many major corporations, the Delaware judiciary has become particularly familiar with matters of corporate law, and a substantial body of court decisions has developed construing Delaware's corporation laws. As a result, Delaware corporate law has been, and is likely to continue to be, interpreted and explained in a number of significant court decisions, a circumstance which will provide greater predictability with respect to our legal affairs. In contrast, the Wyoming Business Corporation Act, to which BioSante Wyoming is currently 19

subject, was only recently enacted in its current form (becoming generally effective on January 1, 1990) and has not been the subject of a significant number of judicial decisions interpreting its provisions. EFFECTS OF REINCORPORATION IN DELAWARE BioSante Delaware, which was incorporated on April 11, 2001 for the sole purpose of effecting the merger, has not engaged in any business to date and has no assets. The merger will not result in any change to BioSante Wyoming business, management, location of BioSante Wyoming's principal executive offices or other facilities, capitalization, assets or liabilities. BioSante Wyoming's employee benefit arrangements will be continued by BioSante Delaware upon the same terms and subject to the same conditions. In management's judgment, none of BioSante Wyoming's presently contemplated activities will be either favorably or unfavorably affected in any material respect by adoption of the reincorporation proposal. As shareholders of our company, however, you should consider that the corporation law of Delaware and the corporation law of Wyoming differ in a number of significant respects, including differences pertaining to the rights of shareholders. We encourage you to carefully review the discussion of some of these differences under the heading "Significant Differences Between the Corporation Laws of Wyoming and Delaware." CERTIFICATE OF INCORPORATION AND BYLAWS TO BE IN EFFECT AFTER THE REINCORPORATION Following the reincorporation, we will be subject to the certificate of incorporation and bylaws of BioSante Delaware. A copy of the certificate of incorporation of BioSante Delaware is attached to this proxy statement as Appendix C, and a copy of the bylaws of BioSante Delaware is attached to this proxy statement as Appendix D. The certificate of incorporation attached as Appendix C is substantially similar to BioSante Wyoming's articles of incorporation. Approval of the reincorporation by our shareholders will automatically result in the adoption of the certificate of incorporation and bylaws of BioSante Delaware. SIGNIFICANT DIFFERENCES BETWEEN THE CORPORATION LAWS OF WYOMING AND DELAWARE The rights and preferences of our shareholders are presently governed by the Wyoming Business Corporations Act. Upon the reincorporation of our company under the laws of the State of Delaware, these rights and preferences will be governed by the Delaware General Corporation Law. Although Delaware and Wyoming corporation laws currently in effect are similar in many respects, certain differences will affect the rights of our shareholders if the reincorporation is completed. The following discussion summarizes the primary differences considered by management to be significant and is qualified in its entirety by reference to the full text of the Wyoming Business Corporation Act and Delaware General Corporation Law. SHAREHOLDER VOTING Under both Wyoming law and Delaware law, action on certain matters, including the sale, lease or exchange of all or substantially all of the corporation's property or assets other than in the usual and regular course of business, mergers, and consolidations and voluntary dissolution, must be approved by the holders of a majority of the outstanding shares. In addition, both states' laws provide that the articles or certificate of incorporation may provide for a supermajority of the voting power of the outstanding shares to approve such extraordinary corporate transactions. APPRAISAL RIGHTS IN CONNECTION WITH CORPORATE REORGANIZATIONS AND OTHER ACTIONS Under Wyoming law and Delaware law, shareholders have the right, in some circumstances, to dissent from certain corporate transactions by demanding payment in cash for their shares equal to the fair value of the shares as determined by the corporation or by a court in the event a dissenting shareholder does not agree with the fair value established by the corporation. Wyoming law, in general, entitles a 20

shareholder to dissent from, and to obtain payment of the fair market value of his, her or its shares, upon (i) certain amendments to BioSante Wyoming's articles of incorporation that materially and adversely affect the rights or preferences in respect of the shares of the dissenting shareholder, (ii) upon the sale or exchange of substantially all corporate assets other than in the usual and regular course of business if the shareholder is entitled to vote on the sale or exchange, and (iii) upon merger, consolidation or share exchange by a corporation, regardless of whether the shares of the corporation are listed on a national securities exchange or widely held. Delaware law allows for dissenters' rights only in connection with certain mergers or consolidations. No such appraisal rights exist, however, for corporations whose shares are listed on a national securities exchange or held of record by more than 2,000 stockholders unless the certificate of incorporation provides otherwise (BioSante Delaware's certificate of incorporation does not provide otherwise) or the shareholders are to receive in the merger or consolidation anything other than (a) shares of stock of the corporation surviving or resulting from such merger or consolidation, (b) shares of stock of any other corporation which at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 shareholders, (c) cash in lieu of fractional shares of the corporation described in the foregoing clauses (a) and (b), or (d) any combination of (a), (b) or (c). The procedures for asserting dissenters' rights in Delaware impose most of the initial costs of the assertion on the dissenting shareholder, whereas in Wyoming costs of an appraisal proceeding (not including attorney fees) are generally assessed against the corporation. If, however, the court finds that the dissenters acted arbitrarily, vexatiously, or not in good faith in initiating an assessment proceeding, the court has discretion to assess costs against some or all dissenters. A Wyoming court may assess the fees and expenses of counsel and experts for each party in amounts the court finds equitable. The court's decision will be based on whether or not the corporation substantially complied with the dissenters' rights statutes and whether the corporation or dissenters acted arbitrarily, vexatiously, or not in good faith. ACTION BY SHAREHOLDERS WITHOUT A MEETING Under Wyoming law, any action required or permitted to be taken at a shareholders' meeting may be taken without a meeting by written consent signed by all of the shareholders entitled to vote on such action. This power cannot be restricted by a Wyoming corporation's articles of incorporation. Delaware law permits such an action to be taken if the written consent is signed by the holders of shares that would have been required to effect the action at an actual meeting of the stockholders. Generally, holders of a majority of outstanding shares could effect such an action. However, Delaware law also provides that a corporation's certificate of incorporation may restrict or prohibit stockholders' action without a meeting. BioSante Delaware's certificate of incorporation does not contain any such restriction. ACTION BY DIRECTORS WITHOUT A MEETING Wyoming and Delaware law each permit directors to take unanimous written action without a meeting in an action otherwise required or permitted to be taken at a board meeting. CONFLICTS OF INTEREST Under both Wyoming law and Delaware law, a contract or transaction between a corporation and one or more of its directors, or an entity in or of which one or more of the corporation's directors are directors, officers, or legal representatives or have a material financial interest, is not void or voidable solely by reason of the same, provided that the contract or transaction is fair and reasonable at the time it is authorized and is ratified by the corporation's stockholders after disclosure of the relationship or interest, or is authorized in good faith by a majority of the disinterested members of the board of directors after disclosure of the relationship or interest. However, if the contract or transaction is authorized by the board, under 21

Wyoming law the interested director may not be counted in determining the presence of a quorum. Delaware law permits the interested director to be counted in determining whether a quorum of the directors is present at the meeting approving the contract or transaction, and further provides that the contract or transaction shall not be void or voidable solely because the interested director's vote is counted at the meeting which authorizes the contract or transaction. BioSante Wyoming currently has a conflicts of interest policy that will be assumed by BioSante Delaware upon completion of the merger. This policy provides that no director shall participate in any discussion or consideration involving a conflict of interest related to the relationship between BioSante Wyoming, on the one hand, and such director or any of his or her affiliates, on the other hand. DIRECTORS' STANDARD OF CARE AND PERSONAL LIABILITY Wyoming law provides that a director must discharge his or her duties in good faith, in a manner the director reasonably believes to be in the best interests of the corporation, and with the care an ordinarily prudent person in a like position would exercise under similar circumstances. In discharging his or her duties, a director is entitled to rely on information, opinions, reports or statements, if prepared by (i) officers or employees of the corporation whom the director reasonably believes to be reliable and competent in the matters presented, (ii) legal counsel, public accountants or other persons relating to matters the director reasonably believes are within the person's professional or expert competence, or (iii) a committee of the board of directors of which he or she is not a member if the director reasonably believes the committee merits confidence. A director is not acting in good faith if he or she has knowledge concerning the matter in question that makes reliance otherwise permitted by Wyoming law unwarranted. A director who performs his or her duties consistent with the requirements under Wyoming law, may not be held liable for any action taken as a director or any failure to take any action. Delaware law provides that the board of directors has the ultimate responsibility for managing the business affairs of a Delaware corporation. In discharging this function, Delaware law holds directors to fiduciary duties of care and loyalty to the corporation and its stockholders. Delaware courts have held that the duty of care requires the exercise of an informed business judgment. An informed business judgment means that the directors have informed themselves of all material information reasonably available to them. Having become so informed, they then must act with requisite care in the discharge of their duties. Liabilities of directors of a Delaware corporation to the corporation or its stockholders for breach of the duty of care requires a finding by the court that the directors were grossly negligent in their decision-making process. The duty of loyalty requires that, in making a business decision, directors act in good faith and with the honest belief that the action taken is in the best interests of the corporation. LIMITATION OR ELIMINATION OF DIRECTOR'S PERSONAL LIABILITY Delaware law provides that if the certificate of incorporation so provides, the personal liability of a director for breach of fiduciary duty as a director may be eliminated or limited, but that the liability of a directors may not be limited or eliminated for: o any breach of the directors' duty of loyalty to the corporation or its shareholders; o acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law; o the payment of unlawful dividends, stock repurchases or redemptions; or o any transaction in which the director received an improper personal benefit. BioSante Delaware's certificate of incorporation contains a provision eliminating the personal liability of its directors for breach of fiduciary duty as a director, subject to the foregoing limitations. Wyoming law had a similar 22

provision but repealed it in 1997. However, Wyoming law provides that a corporation's articles of incorporation may include a provision eliminating or limiting the liability of a director to the corporation or its shareholders for money damages for any action taken, or the failure to take any action, as a director, except liability for (i) any financial benefit unlawfully received by a director, (ii) an intentional infliction of harm on the corporation or its shareholders, (iii) authorizing an unlawful distribution, or (iv) the intentional violation of criminal law. INDEMNIFICATION Wyoming law generally provides for mandatory indemnification of a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he or she was a party because he or she was a director and/or officer against reasonable expenses incurred by him in connection with the proceeding. Wyoming law also generally provides that a corporation may voluntarily indemnify a director or officer acting in an official capacity on behalf of the corporation if such a person acted in good faith, received no improper personal benefit, acted in a manner the person reasonably believed to be in, or not opposed to, the best interests of the corporation and, in the case of a criminal proceeding, had no reasonable cause to believe that the conduct was unlawful. Delaware law permits a corporation to indemnify officers, directors, employees or agents and expressly provides that such indemnification shall not be deemed exclusive of any indemnification right provided under any bylaw, vote of shareholders or disinterested directors or otherwise. Delaware law permits indemnification against expenses and certain other liabilities arising out of legal actions brought or threatened against parties entitled to indemnity for their conduct on behalf of the corporation, provided that each such person acted in good faith and in a manner such person reasonably believed was in or not opposed to the best interests of the corporation. Indemnification is available in a criminal action only if the person seeking indemnity had no reasonable cause to believe that the person's conduct was unlawful. Delaware law does not allow indemnification for directors in the case of an action by or in the right of the corporation (including stockholder derivative suits) as to which such director shall have been adjudged to be liable to the corporation unless indemnification (limited to expenses) is ordered by a court. The certificate of incorporation of BioSante Delaware provides for indemnification to the full extent permitted by Delaware law. CLASSIFIED BOARD OF DIRECTORS Both Wyoming and Delaware permit a corporation's articles or certificate of incorporation to provide for a classified board of directors. Delaware and Wyoming law permits a maximum of three classes. Neither BioSante Wyoming's articles of incorporation nor the certificate of incorporation of BioSante Delaware provide for a classified board of directors. CUMULATIVE VOTING FOR DIRECTORS Under Wyoming and Delaware law, cumulative voting for directors is not available to shareholders unless the articles or certificate of incorporation provides otherwise. Neither BioSante Wyoming's articles of incorporation nor BioSante Delaware's certificate of incorporation provide for cumulative voting in elections of directors. REMOVAL OF DIRECTORS Under Wyoming law, unless a corporation's articles of incorporation provide otherwise, a director may be removed with or without cause by the affirmative vote of a majority of the shareholders, however, if the director to be removed was named by a voting group of shareholders, only the shareholders of that voting group may remove the director. Under Delaware law, a director of a corporation may be removed with or without cause by the affirmative vote of a majority of shares entitled to vote for the election of directors. 23

VACANCIES ON BOARD OF DIRECTORS Under Wyoming law, unless the articles of incorporation provide otherwise, (a) a vacancy on a corporation's board of directors may be filled by the vote of a majority of directors then in office, although less than a quorum, the shareholders, or if the vacancy was held by a director elected by a voting group of shareholders, only the holders of shares of that voting group are entitled to vote to fill the vacancy, (b) a newly created directorship resulting from an increase in the number of directors may be filled by the board or the shareholders, and (c) any director so elected shall hold office only until a qualified successor is elected at the next regular or special meeting of shareholders. BioSante Wyoming's bylaws provided that the remaining members of the board will fill any vacancy on the board or any newly created directorship resulting from an increase in the number of directors by an action of the board. Under Delaware law, a vacancy on a corporation's board of directors may be filled by a majority of the remaining directors, although less than a quorum, or by the affirmative vote of a majority of the outstanding voting shares, unless otherwise provided in the certificate of incorporation or bylaws. BioSante Delaware's bylaws provide that a vacancy on a board of directors shall be filled by the affirmative vote of a majority of the remaining directors. ANNUAL MEETINGS OF SHAREHOLDERS Wyoming law provides for annual meetings of shareholders and BioSante Wyoming bylaws follow these provisions. Delaware law provides that if no date has been set for an annual meeting of stockholders for a period of 13 months after the last annual meeting, the Delaware court may order a meeting to be held upon the application of any stockholder or director. SPECIAL MEETINGS OF SHAREHOLDERS Wyoming law provides that the board of directors or person or persons authorized in the articles of incorporation or bylaws to call a special meeting, or a shareholder or shareholders holding 10% or more of the votes entitled to be cast on any issue proposed to be considered at the proposed special meeting, may call a special meeting of the shareholders. Under Delaware law, only the board of directors or those persons authorized by the corporation's certificate of incorporation or bylaws may call a special meeting of the corporation's stockholders. The bylaws of BioSante Delaware provide that special meetings may be called by the Board of Directors, the Chairman of the Board, the Chief Executive Officer or at the request of stockholders owning a majority of the voting power of the outstanding shares entitled to vote. INSPECTION OF SHAREHOLDER LISTS Under Wyoming law, any shareholder of a corporation has an absolute right to examine and, subject to certain limitations, copy, in person or by a legal representative, during regular business hours a list of the shareholders who are entitled to notice of a shareholders meeting beginning two business days after notice of a meeting has been given by a corporation for which the shareholder list was prepared. Otherwise, only holders of at least 5% of the outstanding shares who have been shareholders for at least six months have the right to inspect the corporation's record of shareholders (and certain other corporate records), provided they give five days written notice and the demand to inspect the corporation's record of shareholders (and certain other corporate records) is made (i) in good faith and for a proper purpose, (ii) the demand describes with reasonable particularity the purpose and records they seek to inspect, and (iii) the records are directly related with the stated purpose. Under Delaware law, any stockholder, upon written demand under oath stating the purpose thereof, has the right during the usual hours for business to inspect for any proper purpose a list of the corporation's stockholders and to make copies or extracts therefrom. AMENDMENT OF THE CHARTER Under Wyoming law, before the shareholders may vote on an amendment to the articles of incorporation, requiring shareholder approval, a 24

resolution to amend the articles must have been approved by the affirmative vote of the majority of the directors present at the meeting where such resolution was considered. The directors must also recommend the amendment to the shareholders (unless the directors determine that they should make no such recommendation because of special circumstances or a conflict of interest) prior to its vote on the amendment. Most amendments to the articles of incorporation require the affirmative vote of the holders of the majority of the voting power present and entitled to vote at the meeting (and of each class, if entitled to vote as a class), unless the articles of incorporation, directors, or Wyoming Business Corporation Act require a larger proportion. Wyoming law provides that a proposed amendment may be voted upon by the holders of a class or series even if the articles of incorporation would deny that right, if among other things, the proposed amendment would increase or decrease the aggregate number of authorized shares of the class or series, change the rights or preferences of the class or series, create a new class or series of shares having rights and preferences prior and superior to the shares of that class or series or limit or deny any existing preemptive right of the shares of the class or series. Under Delaware law, the board of directors must adopt a resolution setting forth an amendment to the certificate of incorporation before the stockholders may vote on such amendment. Unless the certificate of incorporation provides otherwise, amendments to the certificate of incorporation generally require the approval of the holders of a majority of the outstanding stock entitled to vote thereon, and if the amendment would increase or decrease the number of authorized shares of any class or series or the par value of such shares, or would adversely affect the rights, powers or preferences of such class or series, a majority of the outstanding stock of such class or series also must approve the amendment. AMENDMENT OF THE BYLAWS Wyoming law provides that the incorporators or board of directors shall adopt initial bylaws for a corporation. Thereafter, unless (i) reserved by the articles of incorporation or the Wyoming Business Corporation Act exclusively to the shareholders (in whole or in part), or (ii) the shareholders in amending or repealing a particular bylaw provide expressly that the board of directors may not amend or repeal that bylaw, either the board of directors or shareholders may amend or repeal a corporation's bylaws. After adoption of initial bylaws, the board of directors of a Wyoming corporation cannot adopt, amend, or repeal a bylaw fixing a greater quorum or voting requirement for shareholders or voting groups of shareholders than required by Wyoming law. An amendment to the bylaws that fixes a greater quorum or voting requirement for the board of directors may be amended or repealed (i) if originally adopted by the shareholders, only by the shareholders, (ii) if originally adopted by the board of directors, either by the shareholders or by the board of directors. Delaware law provides that the power to adopt, amend or repeal bylaws remains with the corporation's stockholders, but permits the corporation, in its certificate of incorporation, to place such power in the board of directors. Under Delaware law, the fact that such power has been placed in the board of directors neither divests nor limits the stockholders' power to adopt, amend, or repeal bylaws. BioSante Delaware's certificate of incorporation places the power to adopt, amend or repeal bylaws in its board of directors. PROXIES Both Wyoming and Delaware law permit proxies of definite duration. In the event the proxy is indefinite as to its duration, under Wyoming law it is valid for 11 months, under Delaware law, for three years. PREEMPTIVE RIGHTS Under Wyoming law, shareholders do not have preemptive rights to acquire a certain fraction of the unissued securities or rights to purchase securities of a corporation before the corporation may offer them to other persons, unless the corporation's articles of incorporation otherwise provide. BioSante Wyoming's articles of 25

incorporation provide that no such preemptive right exists in our shareholders. Under Delaware law, no such preemptive right will exist, unless the corporation's certificate of incorporation specifies otherwise. BioSante Delaware's certificate of incorporation does not provide for any such preemptive rights. DIVIDENDS Generally, a Wyoming corporation may pay a dividend if its board of directors determines that the corporation will be able to pay its debts in the ordinary course of business after paying the dividend and if, among other things, the dividend payment does not reduce the remaining net assets of the corporation below the corporation's total liabilities plus the amount that would be needed, if the corporation were to be dissolved at the time of the distribution, to satisfy the preferential rights, upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution. Any such dividend is also subject to any additional restrictions contained in the corporation's articles of incorporation. A Delaware corporation may pay dividends out of surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or for the preceding fiscal year, except that dividends may not be paid out of net profits if, after the payment of the dividend, capital is less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets. STOCK REPURCHASES A Wyoming corporation may acquire its own shares and such shares so acquired shall constitute authorized but unissued shares. Any such share acquisition is only proper under Wyoming law if a corporation's board of directors determines that the corporation will be able to pay its debts in the ordinary course of business after acquiring the shares and if, among other things, the share acquisition does not reduce the remaining net assets of the corporation below the corporation's total liabilities plus the amount that would be needed, if the corporation were to be dissolved at the time of the share acquisition, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior. Under Delaware law, a corporation may purchase or redeem shares of any class except when its capital is impaired or such purchase would cause impairment of capital, except that a corporation may purchase or redeem out of capital any of its preferred shares if such shares will be retired upon the acquisition and the capital of the corporation will be thereby reduced. TREASURY SHARES UNDER DELAWARE LAW Under the Delaware General Corporation Law, we may hold treasury shares and these shares may be held, sold, lent, pledged or exchanged by us. Treasury shares, however, are not outstanding shares and therefore do not receive any dividends and do not have voting rights. The Wyoming Business Corporation Act provides that a corporation may have authorized but unissued shares. Any shares that are authorized but unissued are not considered outstanding shares. Wyoming law does not specifically permit a corporation to pledge unissued shares. VOLUNTARY DISSOLUTION Wyoming law provides that a corporation may be voluntarily dissolved upon the directors' approval of and recommendation to the shareholders to dissolve and approval by the holders of a majority of a corporation's shares entitled to vote at a meeting called for the purpose of considering such dissolution unless a greater approval is required by the directors, the articles of incorporation or the Wyoming Business Corporation Act. Delaware law provides that voluntary dissolution of a corporation first must be deemed advisable by a majority of the board of directors and then approved by a majority of the outstanding stock entitled to vote. Delaware law further provides for voluntary dissolution of a corporation without action of the directors if all of the stockholders entitled to vote on such dissolution shall have consented to the dissolution in writing. 26

JUDICIAL DISSOLUTION Wyoming law provides that a court may dissolve a corporation in an action by a shareholder where: (a) the directors are deadlocked in the management of corporate affairs and the shareholders cannot break the deadlock and irreparable injury to the corporation is threatened or being suffered; (b) the directors have acted fraudulently, illegally, or in an oppressive manner; (c) the shareholders are deadlocked in voting power for two consecutive annual meetings to elect successors to directors whose terms have expired; or (d) there is a case of misapplication or waste of corporate assets. Delaware law provides that courts may revoke or forfeit the charter of any corporation for non-use, misuse or nonuser of its corporate powers, privileges or franchises. ANTI-TAKEOVER LEGISLATION The Delaware General Corporation Law contains a business combination statute which is intended to protect shareholders from individuals or companies attempting a takeover of a corporation in certain circumstances. The Wyoming Business Corporation Act does not have a comparable provision that applies to BioSante Wyoming. The following is a summary of the Delaware business combination statute. The Delaware business combination statute provides that if a person acquires 15% or more of the voting stock of a Delaware corporation, the person is designated an interested stockholder and the corporation may not engage in certain business combinations with this person for a period of three years. However, an otherwise prohibited business combination may be permitted if one of three conditions is met: o First, if prior to the date the person became an interested stockholder, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder, then the business combination is permitted. o Second, a business combination is permitted if the tender offer or other transaction pursuant to which the person acquires 15% stock ownership is attractive enough such that the interested stockholder is able to acquire ownership in the same transaction of at least 85% of the outstanding voting stock (excluding for purposes of determining the number of shares outstanding those shares owned directors who are also officers and shares owned by certain employee stock ownership plans). o Finally, the business combination is permissible if approved by the board and authorized at an annual or special meeting of stockholders (action by written consent is not permitted) by the affirmative vote of two-thirds of the outstanding voting shares held by disinterested stockholders. Only certain Delaware corporations are subject to the business combination statute. A corporation is subject to the statute if it is incorporated under the laws of Delaware and has a class of voting stock that is listed on a national securities exchange, quoted on an inter-dealer quotation system of a registered national securities association, or held of record by more than 2,000 shareholders. Only certain "business combinations" are prohibited under Delaware law. A business combination is defined broadly to include any of the following: o any merger or consolidation with the interested stockholder; o any sale, transfer or other disposition of assets to the interested stockholder if the assets have a market value equal to or greater than 10% of the aggregate market value of all of the corporation's assets; o any transfer of stock of the corporation to the interested stockholder, except for transfers in a conversion or exchange or a pro rata distribution; and o any receipt by the interested stockholder of any loans, advances, guarantees, pledges, 27

and other financial benefits, except in connection with a pro rata transfer. The Delaware statute does not apply to any business combination in which the corporation, with the support of a majority of those directors who were serving as directors before any person became an interested stockholder, proposes a merger, sale, lease, exchange or other disposition of at least 50% of its assets, or supports (or does not oppose) a tender offer for at least 50% of its voting stock. In such a case, all interested stockholders are released from the three year prohibition and may compete with the corporation-sponsored transaction. In Delaware, an otherwise prohibited business combination may be permitted by board approval, by stockholder approval, or by an acquisition of 85% of the outstanding shares of voting stock. In addition, the Delaware statute provides that if the corporation proposes a merger or sale of assets, or does not oppose a tender offer, all interested stockholders are released from the three year prohibition and may compete with the company-sponsored transaction in certain circumstances. The Delaware General Corporation Law permits a corporation to "opt out" of the business combination statute by electing to do so in its certificate of incorporation or bylaws within a specified time period. Neither BioSante Delaware's certificate of incorporation nor the bylaws of BioSante Delaware contain such an "opt out" provision. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER The reincorporation is intended to be tax free under the Internal Revenue Code. Accordingly, you will recognize no gain or loss for federal income tax purposes as a result of the completion of the reincorporation. You will have a tax basis in the shares of capital stock of BioSante Delaware equal to your tax basis in your shares of capital stock of BioSante Wyoming. Provided that you have held your shares of capital stock of BioSante Wyoming as a capital asset, your holding period for the shares of capital stock of BioSante Delaware will include the holding period of the shares of capital stock of BioSante Wyoming. Neither we nor BioSante Delaware will recognize any gain or loss for federal income tax purposes as a result of the reincorporation, and BioSante Delaware will succeed, without adjustment, to our tax attributes. YOU SHOULD CONSULT YOUR OWN TAX ADVISERS AS TO THE PARTICULAR TAX CONSEQUENCES TO YOU OF THE REINCORPORATION UNDER STATE, LOCAL OR FOREIGN TAX LAWS. DISSENTERS' RIGHTS Under the Wyoming Business Corporation Act, you are or may be entitled to dissent from the reincorporation proposal and obtain "fair value" plus interest for your shares by asserting your dissenters' rights. For purposes of dissenters' rights, "fair value" means the value of the shares immediately before the effective time of the reincorporation, and "interest" means interest commencing at the effective time of the reincorporation up to and including the date of payment at the average rate currently paid by BioSante Wyoming on its principal bank loans, or, if none, at a rate that is fair and equitable under the circumstances. The following is a summary of your dissenters' rights under the Wyoming Business Corporation Act. Because it is a summary, it does not include all of the information that you will need to exercise properly your dissenters' rights. You should read the dissenters' rights provisions in Article 13 of the Wyoming Business Corporation Act, the full text of which is attached to this proxy statement as Appendix E, carefully and in its entirety because it, and not this summary description, defines your rights to dissent. If you choose either to assert your dissenters' rights or preserve your right to dissent, you should carefully review the requirements under Article 13 of the Wyoming Business Corporation Act (Dissenters' Rights Statutes) and consult with an attorney. 28

If your shares are held of record in the name of another person, such as a bank, broker or other nominee, you must act promptly to cause the record holder to follow the steps summarized below properly and in a timely manner in order to perfect whatever dissenters' rights you may have. A DISSENTING SHAREHOLDER MUST PERFECT DISSENTERS' RIGHTS If you elect to exercise your dissenters' rights, to "perfect" them, you must: o provide us with written notice of your intention to demand payment of the fair value of your shares before the shareholders vote on the reincorporation proposal at the annual and special meeting on June 13, 2001; o not vote your shares in favor of the merger agreement and reincorporation; and o assert your dissenters' rights as to all of your shares (except where certain shares are beneficially owned by another person but registered under your name so long as you dissent with respect to all shares beneficially owned by any one person). The written notice must reasonably inform us of your identity and your intention to exercise your dissenters' rights. All written notices should be: o addressed to: BioSante Pharmaceuticals, Inc. 175 Olde Half Day Road Suite 247 Lincolnshire, IL 60069 Attn: Secretary o filed before the shareholders vote on the reincorporation proposal at the annual and special meeting on June 13, 2001; and o executed by, or sent with the written consent of, the holder of record. A failure to vote will not constitute a waiver of your dissenters' rights, but a vote in favor of the reincorporation by proxy or in person will constitute a waiver of your dissenters' rights and will override any previously filed written notice of intent to demand payment. A signed proxy returned with no indication of how it should be voted (or an abstention) will be a vote for the merger agreement and reincorporation and will therefore constitute a waiver of your dissenters' rights. If you fail to comply with these conditions and all other conditions imposed by the Wyoming Business Corporation Act, you will have no dissenters' rights with respect to your shares. WE MUST PROVIDE DISSENTING SHAREHOLDERS WITH WRITTEN NOTICE If you have properly asserted your intention to demand payment for your shares if the proposed merger and reincorporation is effectuated, we must give you a written notice no later than 10 days after the corporate action was taken and the notice must contain the following: o the address where your demand for payment and where and when stock certificates must be sent; o any restrictions on transfer of uncertificated shares that will apply after the demand for payment is received; o a form for demanding payment that includes the date of the first announcement to news media or to shareholders of the terms of the proposed action and requires that the person asserting dissenters' rights certify the date on which you, or the beneficial owner on whose behalf you dissent, acquired the shares or an interest in them; o the date when your payment demand and stock certificates must be received; and o a copy of Article 13 of the Wyoming Business Corporation Act (Dissenters' Rights Statutes). 29

DISSENTING SHAREHOLDERS MUST DEMAND PAYMENT AND RETURN SHARES By no later than the date set forth in the written notice described above, you must demand payment, certify whether you acquired beneficial ownership of the shares before the announcement of the reincorporation and deposit your stock certificate with BioSante Delaware, or you will irrevocably forfeit your dissenters' rights. You will retain all rights as a shareholder until the effective time of the reincorporation. WE MUST SEND DISSENTING SHAREHOLDERS PAYMENT OF FAIR VALUE AND OTHER INFORMATION If you make a proper demand for payment and deposit your stock certificates, then we will send you an amount that we estimate to be the fair value of your shares, plus accrued interest. The payment for fair value must be accompanied by the following: o our closing balance sheet, statement of income and a statement of changes in shareholders' equity for a fiscal year ending not more than 16 months before the date of payment; o our latest available interim financial statements; o a statement of our estimate of the fair value of your shares; o an explanation of the method used to calculate interest; o a brief description of the procedures to be followed if you wish to demand supplemental payment in the event you are dissatisfied with the estimate of the fair value of your share(s) and offered payment; and o a copy of Article 13 of the Wyoming Business Corporation Act (Dissenters' Rights Statutes). If, however, the merger is not completed within sixty (60) days after the date set for demanding payment and depositing your share certificates or if you do not comply with all of the requirements for exercising dissenters' rights under Wyoming law and as herein provided, we will not send you the fair value of your shares or the additional information listed above. In such a case we will return any previously deposited share certificates and release any transfer restriction on uncertificated shares. A DISSENTING SHAREHOLDER MAY DEMAND SUPPLEMENTAL PAYMENT If you believe the amount of the payment as calculated by us is less than the fair value of your shares, plus interest, you must give written notice to us of your own estimate of the fair value of your shares, plus interest, within 30 days after the date we send you our fair value estimate and payment. Your written notice must also demand payment for the difference between your fair value estimate and the payment already made by us. If you fail to give written notice of your estimate to us and demand payment for the difference within the 30-day time period, you will be entitled only to the amount we estimated as fair value and previously paid to you. These demand procedures also apply (i) in the event we fail to make payment of our estimated fair value of your shares within sixty (60) days after the date set for demanding payment, or (ii) we fail to carryout the merger and reincorporation and do not return your previously deposited certificates (or release any restrictions on uncertificated shares) within sixty (60) days after the date set for demanding payment. A COURT WILL SETTLE FAIR VALUE DISPUTES If we cannot agree within 60 days after we receive your estimate of the fair value of your shares, then we will file an action in a court of competent jurisdiction in Laramie County, Wyoming within such 60 day period, asking the court to determine the fair value of your shares, plus interest. If your payment demand is not settled within the applicable 60-day settlement period, you will be made a party to this proceeding. If we fail to petition the court to determine fair value within this sixty (60) day period, we shall pay each dissenter whose demand is unsettled the amount demanded (less any amount previously paid by us). After notice to you, the court will determine the fair value of your shares. The court may appoint 30

one or more persons as appraisers to receive evidence and make a fair value recommendation to the court. You will be entitled to discovery on the same basis as any other party to a civil action. The court will determine the fair value of your shares by taking into account any and all factors the court finds relevant. If the court determines that the fair value of your shares is in excess of our estimate of the fair value of the shares, then the court will enter a judgment in your favor in an amount by which the value determined by the court exceeds our estimate and previous payment of the fair value, plus interest. WE MAY WITHHOLD THE PAYMENT OF FAIR VALUE UNDER CERTAIN CIRCUMSTANCES If you were not a shareholder or are not dissenting on behalf of a person who was a beneficial owner of BioSante Wyoming on April 23, 2001, we may withhold the payment of the estimated fair value, plus interest, for your or such person's shares. To the extent we elect to withhold payment in such a manner, after the reincorporation is complete we must deliver to you: o an estimate the fair value of your shares, plus accrued interest and pay this amount to each dissenter who agrees to accept it in full satisfaction of his, hers or its demand; o a statement of our estimate of the fair value of your shares; o an explanation of how the interest was calculated; and o a brief description of the procedures to be followed if you wish to demand supplemental payment in the event you are dissatisfied with our estimate of the fair value of your share(s) and offered payment. ------------- If you are considering seeking appraisal of your shares, you should realize that the fair value of your shares, as determined under Article 13 of Wyoming Business Corporation Act (Dissenters' Rights Statutes), could be more than, the same as, or less than the amount of value of the shares of BioSante Delaware shares you will be deemed to have received as a result of the reincorporation of our company in Delaware. IF YOU FAIL TO COMPLY FULLY WITH THE STATUTORY PROCEDURE SUMMARIZED ABOVE, YOU WILL FORFEIT YOUR RIGHT TO DISSENT. VOTE REQUIRED Approval of the merger agreement and reincorporation requires the affirmative vote of the holders of a majority of the outstanding shares of common stock and class C stock, voting as a single class. A vote for the proposal will constitute specific approval of the merger agreement, the reincorporation and merger, BioSante Delaware's certificate of incorporation, bylaws and all transactions and proceedings related to the reincorporation and the merger described in this proxy statement. BOARD RECOMMENDATION The Board of Directors recommends a vote FOR approval of the proposal to change the state of our incorporation from Wyoming to Delaware. 31

RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS (PROPOSAL 4) ------------------------ APPOINTMENT OF AUDITORS The Board of Directors has appointed Deloitte & Touche L.L.P. as our independent auditors for the year ending December 31, 2001. Deloitte & Touche L.L.P. has acted as our independent auditors since January 1, 1999. Prior to that date, Deloitte & Touche, C.A. in Canada acted as our independent auditors since our inception in August 1996. Although it is not required to do so, the Board of Directors wishes to submit the selection of Deloitte & Touche L.L.P. to the shareholders for ratification. If you do not ratify the appointment of Deloitte & Touche L.L.P., another firm of independent auditors will be considered by the Board of Directors. Representatives of Deloitte & Touche L.L.P. will be present at the Annual and Special Meeting via telephone, will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions. PRINCIPAL ACCOUNTING FEES Aggregate audit fees of $32,000 were billed to BioSante for the fiscal year ended December 31, 2000 by BioSante's principal accounting firm, Deloitte & Touche L.L.P., the member firms of Deloitte & Touche Tohmatsu, and their respective affiliates (collectively, Deloitte). FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES Deloitte did not render any services to us in 2000 with respect to financial information systems design and implementation. ALL OTHER FEES Deloitte's fees for all other services rendered to us during 2000 were $34,000 which were for various services in connection with our SEC filings. The audit committee has considered whether the provision of these services is compatible with maintaining Deloitte's independence. VOTE REQUIRED The affirmative vote of the holders of a majority of the shares of our common stock and class C stock, present in person or by proxy on this matter at the Annual and Special Meeting, voting together as a single class, is necessary for the ratification of Deloitte & Touche L.L.P., as our independent auditors for the year ending December 31, 2001.

APPENDIX A BIOSANTE PHARMACEUTICALS, INC. AUDIT COMMITTEE OF THE BOARD OF DIRECTORS CHARTER ORGANIZATION There shall be a committee of the board of directors of BioSante Pharmaceuticals, Inc. ("BioSante") to be known as the audit committee. The membership of the committee shall consist of at least three directors who are generally knowledgeable in financial and auditing matters, including being able to read and understand fundamental financial statements, such as BioSante's balance sheet, statements of operations and statement of cash flows and shall meet the experience requirements for serving on audit committees as set forth in the corporate governance standards of the National Association of Securities Dealers, Inc. Each member of the committee shall be free of any relationship that, in the opinion of the board, would interfere with the member's individual exercise of independent judgment, and shall meet the director independence requirements for serving on audit committees as set forth in the corporate governance standards of the National Association of Securities Dealers, Inc. The board of directors shall appoint one member of the audit committee as chair. The chair shall be responsible for leadership of the committee, including preparing the agenda, presiding over the meetings, making committee assignments and reporting to the board of directors. The chair will also maintain regular liaison with BioSante's Chief Executive Officer, Chief Financial Officer and the lead independent audit partner. ROLE The audit committee of the board of directors assists the board in fulfilling its responsibility for oversight of the quality and integrity of the accounting, auditing and reporting practices of BioSante and other such duties as directed by the board. The committee is expected to maintain free and open communication (including private executive sessions as least annually) with the independent accountants and the management of BioSante, in discharging this role. While the audit committee has the responsibilities and powers set forth in this charter, it is not the duty of the audit committee to plan or conduct audits or to determine that BioSante's financial statements are fairly presented and are in accordance with generally accepted accounting principles. Management is responsible for the preparation of financial statements in accordance with generally accepted accounting principles.

Nor is it the duty of the audit committee to conduct investigations, to resolve disagreements, if any, between management and the independent auditor or to assure compliance with laws and regulations and BioSante's business conduct guidelines. AUTHORITY Subject to the prior approval of the board of directors, the audit committee is granted the authority to investigate any matter or activity involving financial accounting and financial reporting, as well as the internal controls of BioSante. In that regard, the audit committee will have the authority to approve the retention of external professionals to render advice and counsel in such matters. All employees will be directed to cooperate with respect thereto as requested by members of the audit committee. A-1

RESPONSIBILITIES The audit committee's primary responsibilities include: o Recommending to the board of directors the independent accountant to be selected or retained to audit the financial statements of BioSante.

The audit committee has the authority and responsibility to select, evaluate and recommend to the board of directors replacement of the independent accountants. The independent accountants are ultimately accountable to the board of directors of BioSante. o Overseeing the independent auditor relationship by discussing with the auditor the nature and scope of the audit process, receiving and reviewing audit reports, and providing the auditor full access to the committee (and board) to report on any and all appropriate matters. o Discussing with the independent accountants and BioSante's financial and accounting personnel, the adequacy and effectiveness of the accounting and financial controls of BioSante and the quality of BioSante's accounting principles as applied in its financial reporting, including reviews of estimates, reserves and accruals, review of judgmental areas, review of audit adjustments whether or not recorded and such other inquiries as may be appropriate, and elicit recommendations from the independent accountants for the improvement of such internal control procedures or particular areas where new or more detailed controls or procedures may be desirable. o Providing sufficient opportunity for the independent accountants to meet with the members of the audit committee without members of management present. Among the items to be discussed in these meetings are the independent accountants' evaluation of BioSante's financial and accounting personnel and the cooperation that the independent accountants received during the course of the audit. o Discussing with management the status of pending litigation (if any), taxation matters and other areas of oversight to the legal and compliance area as may be appropriate. o Discussing with the independent accountants the matters required to be discussed by Statement on Auditing Standards (SAS) No. 61. o Reviewing the audited financial statements and discussing them with management and the independent auditor. These discussions shall include: 1. BioSante's annual financial statements and related footnotes and financial information to be included in the Corporation's Annual Report to Stockholders and Annual Report on Form 10-KSB. 2.

Analyzed and discussed the audited financial statements with management, 2. Discussed with the independent accountants the matters required to be discussed by Statement on Auditing Standards (SAS) No. 61, 3. Received from the independent accountants disclosures regarding the accountants' independence required by Independence Standards Board Standard No. 1, 4. Discussed with the independent accountants the accountants' independence, 5. Considered the non-audit services provided by the independent accountant, and the fees paid for such services, and 6. Recommended to the board of directors that the audited financial statements be included in BioSante's Annual Report on Form 10-KSB for the last fiscal year for filing with the SEC. o Reviewing with management and the independent auditor the quarterly financial information prior to BioSante's filing of Form 10-QSB.

(b) If and whenever the Shares shall be subdivided into a greater or consolidated into a lesser number of Shares, or the Corporation shall issue Shares (or securities exchangeable for or convertible into Shares) to the holders of all or substantially all of the outstanding Shares by way of a dividend or other distribution of Shares (or securities exchangeable for or convertible into Shares), any holder of shares of Class C Special Stock who has not exercised such holder's right of purchase pursuant to Section 3

3 hereof on or prior to the effective date or record date, as the case may be of such subdivision, consolidation, dividend or other distribution, upon the exercise of such right thereafter, shall be entitled to receive, and shall accept, in lieu of the number of Shares to which such holder was theretofore entitled upon such exercise of such right to purchase or convert (and, in the case of a purchase of Shares pursuant to Section 3 hereto, at the Common Stock Purchase Price adjusted in accordance with subsection 5(a) hereof), the aggregate number of Shares that such holder would have been entitled to receive as a result of such subdivision, consolidation, dividend or other distribution as if, on such record date or effective date, as the case may be, such holder had been the registered holder of the number of Shares to which such holder was theretofore entitled upon such exercise of such right to purchase or convert, as the case may be. 5. ADJUSTMENT OF PURCHASE PRICE If the Corporation shall: (a) subdivide its outstanding Common Stock (hereinafter referred to in this paragraph 5 as the "Shares") into a greater number of shares, (b) consolidate the outstanding Shares into a lesser number of shares, or (c) issue Shares or securities exchangeable for or convertible into Shares ("convertible securities") to the holders of all or substantially all of the outstanding Shares by way of a dividend or distribution of Shares or securities convertible into Shares (other than the issue of Shares or convertible securities as dividends paid in the ordinary course), the Common Stock Purchase Price shall, on the effective date of such subdivision or consolidation or on the record date of such dividend or other distribution, as the case may be, be adjusted by multiplying the Common Stock Purchase Price in effect immediately prior to such subdivision, consolidation, dividend or other distribution by a fraction, the numerator of which is the number of outstanding Shares before giving effect to such subdivision, consolidation or stock dividend and the denominator of which is the number of outstanding Shares after giving effect to such subdivision, consolidation, dividend or other distribution (including in the case where convertible securities are distributed, the number of Shares that would have been outstanding had such securities been exchanged for or converted into Shares on such record date). Such adjustment shall be made successively whenever any event referred to in this Section 5 shall occur. 4

6. DISTRIBUTION RIGHTS ON LIQUIDATION If the Corporation is liquidated, dissolved or wound-up or its assets are otherwise distributed among the stockholders by way of repayment of capital, whether voluntary or involuntary and subject to the rights, privileges, and conditions attaching to any series of preference shares of the Corporation: (a) the holders of the Common Stock shall be entitled to share, equally share for share, in the distribution of the remaining assets of the Corporation; and (b) the holders of the Class C Special Stock shall not be entitled to share in the remaining assets of the Corporation.

The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification to employees and agents of the Corporation similar to those conferred in this Article VI to directors and officers of the Corporation. No amendment or repeal of this Article VI shall apply to or have any effect on any right to indemnification provided hereunder with respect to any acts or omission occurring prior to such amendment or repeal. ARTICLE VII No director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty by such a director as a director, except to the extent provided by applicable law (i) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the General Corporation Law of Delaware, or (iv) for any transaction from which such director derived an improper personal benefit.

No 5

amendment to or repeal of this Article VII shall apply to or have any effect on the liability or alleged liability of any director of the Corporation for or with respect to any acts or omissions of such director occurring prior to such amendment or repeal.
