NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

To Be Held May 4, 2006

TO OUR STOCKHOLDERS:

      Notice is hereby given that the annual meeting of the stockholders of Halozyme Therapeutics, Inc., a Nevada corporation, will be held on May 4, 2006, at 9:00 a.m. local time, in the Dana Point room at the San Diego Marriott Hotel located at 11966 El Camino Real, San Diego 92130, for the following purposes:

      Stockholders of record at the close of business on March 31, 2006 are entitled to notice of, and to vote at, this meeting and any adjournment or postponement.

San Diego, California

March 31, 2006

PROXY STATEMENT FOR ANNUAL MEETING OF STOCKHOLDERS

      The accompanying proxy is solicited by the Board of Directors of Halozyme Therapeutics, Inc., a Nevada corporation, for use at its annual meeting of stockholders to be held on May 4, 2006, or any adjournment or postponement thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Stockholders. This Proxy Statement and the enclosed proxy are being mailed to stockholders on or about March 31, 2006.

HISTORICAL NOTE

      Halozyme Therapeutics, Inc. is the product of the March 11, 2004, merger between DeliaTroph Pharmaceuticals, Inc. (“DeliaTroph”), a private biopharmaceutical company, and Global Yacht Services, Inc. (“Global”), a publicly traded yacht chartering and sales company. In the merger, Global issued Common Stock to the former shareholders of DeliaTroph in exchange for all of their interests in DeliaTroph. Although Global conducted limited operations prior to the merger and was the parent entity of DeliaTroph following the merger, the former shareholders of DeliaTroph held approximately 90% of the outstanding voting interest in the combined enterprise immediately after the merger. DeliaTroph’s management and Board of Directors assumed operational control of Global immediately following the merger and Global changed its name to Halozyme Therapeutics, Inc. The historical operations of Global ceased in connection with the merger and the historical operations of DeliaTroph continued. The merger has been treated as a re-capitalization of DeliaTroph for accounting purposes and the historical and financial information presented here and in our Annual Report reflects the pre-merger activities of DeliaTroph and does not include information relating to the activities of Global prior to the merger unless otherwise indicated.

SOLICITATION AND VOTING

      Voting Securities. Only stockholders of record as of the close of business on March 31, 2006, will be entitled to vote at the meeting and any adjournment thereof. As of that time, we had approximately 61.3 million shares of Common Stock outstanding, all of which are entitled to vote with respect to all matters to be acted upon at the annual meeting. Each stockholder of record as of that date is entitled to one vote for each share of Common Stock held by him or her. Our Bylaws provide that a majority of all of the shares of the stock entitled to vote, whether present in person or represented by proxy, shall constitute a quorum for the transaction of business at the meeting. Votes for and against, abstentions and “broker non-votes” will each be counted as present for purposes of determining the presence of a quorum.

      Broker Non-Votes. A broker non-vote occurs when a broker submits a proxy card with respect to shares held in a fiduciary capacity (typically referred to as being held in “street name”) but declines to vote on a particular matter because the broker has not received voting instructions from the beneficial owner. Under the rules that govern brokers who are voting with respect to shares held in street name, brokers have the discretion to vote such shares on routine matters, but not on non-routine matters. Routine matters include the election of directors, increases in authorized common stock for general corporate purposes and ratification of auditors. Non-routine matters include adoptions of, and amendments to, stock plans.

      Solicitation of Proxies. We will bear the entire cost of soliciting proxies. In addition to soliciting stockholders by mail through our employees, we will request banks, brokers and other custodians, nominees and fiduciaries to solicit customers for whom they hold our stock and will reimburse them for their reasonable, out-of-pocket costs. We may use the services of our officers, directors and others to solicit proxies, personally or by telephone, without additional compensation. In addition, we may retain a proxy solicitation firm or other third party to assist us in collecting or soliciting proxies from our stockholders, although we do not currently plan on retaining such a proxy solicitor.

      Voting of Proxies. All valid proxies received before the meeting will be exercised. All shares represented by a proxy will be voted, and where a proxy specifies a stockholder’s choice with respect to any matter to be acted upon, the shares will be voted in accordance with that specification. If no choice is indicated on the proxy, the shares will be voted in favor of the proposal. A stockholder giving a proxy has the power to revoke his or her proxy at any time before it is exercised by delivering to the Secretary of Halozyme a written instrument revoking the proxy or a duly executed proxy with a later date, or by attending the meeting and voting in person.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

      We have a classified Board of Directors that consists of two Class I directors, two Class II directors and two Class III directors. Our directors are elected for a term of three years, with one class of directors up for election every year. In connection with the 2006 annual meeting of stockholders we will be electing two Class II directors, while two Class III directors will be elected at the 2007 annual meeting of stockholders and two Class I directors will be elected at the 2008 annual meeting of stockholders. Once elected, directors serve until their respective successors are duly elected and qualified.

      Management’s Class II nominees for election by the stockholders are John S. Patton and Steven T. Thornton. Both Dr. Patton and Mr. Thornton are current members of our Board of Directors and, if elected, they will serve as directors until our annual meeting of stockholders in 2009 and until their successors are elected and qualified. If either nominee declines to serve or becomes unavailable for any reason, or if a vacancy occurs before the election (although we know of no reason to anticipate that this will occur), the proxies may be voted for such substitute nominees as we may designate.

      If a quorum is present and voting, the two nominees for Class II directors receiving the highest number of votes will be elected as the Class II directors. Abstentions and broker non-votes have no effect on the vote.

      The Board of Directors recommends a vote “FOR” each of the nominees named above.

      The following table sets forth, for our current directors, including the Class II nominees to be elected at this meeting, information with respect to their ages and background:

      The Board of Directors has determined that, other than Drs. Lim and Frost, each of the members of the Board of Directors is an independent director for purposes of the listing requirements of the American Stock Exchange.

Board Meetings and Committees

      The Board of Directors held eight meetings during the fiscal year ended December 31, 2005. The Board of Directors has an Audit Committee, a Compensation Committee and a Nominating and Governance Committee. During the last fiscal year, no director other than Steven T. Thornton attended fewer than 75% of the total number of meetings of the Board and all of the committees of the Board on which such director served during that period. Mr. Thornton joined the Board in June of 2005 and was unable to attend one Board meeting that was scheduled prior to his joining the Board as well as one special meeting of the Board.

      Audit Committee. The members of the Audit Committee are Kenneth J. Kelley (Chairman), Steven T. Thornton and Robert L. Engler. Each of the members of the Audit Committee satisfy the independence requirements established by the rules of the American Stock Exchange. Mr. Kelley is an audit committee financial expert, as defined in the rules of the Securities and Exchange Commission. The primary purpose of the Audit Committee is to oversee our accounting and financial reporting processes and the function of the Audit Committee includes retaining our independent auditors, reviewing their independence, reviewing and approving the planned scope of our annual audit, reviewing and approving any fee arrangements with our auditors, overseeing their audit work, reviewing and pre-approving any non-audit services that may be performed by them, reviewing the adequacy of accounting and financial controls, reviewing our critical accounting policies and reviewing and approving any related party transactions. The Audit Committee held six meetings during the fiscal year ended December 31, 2005.

      Compensation Committee. The members of the Compensation Committee are Steven T. Thornton (Chairman), Robert L. Engler, Kenneth J. Kelley and John S. Patton. Each of the members of the Compensation Committee satisfy the independence requirements established by the rules of the American Stock Exchange. The primary purpose of the Compensation Committee is to discharge the Board’s responsibilities relating to compensation and benefits of our executive officers. The Compensation Committee recommends the salary and bonus earned by the Chief Executive Officer, reviews and approves salary and bonus levels for other executive officers, approves stock option grants to executive officers and other employees and approves all employment and severance agreements. The Compensation Committee held six meetings during the fiscal year ended December 31, 2005.

      Nominating and Governance Committee. The members of the Nominating and Governance Committee are Robert L. Engler (Chairman), Kenneth J. Kelley and Steven T. Thornton. Each of the members of the Nominating and Governance Committee satisfy the independence requirements established by the rules of the American Stock Exchange. The primary responsibilities of the Nominating and Governance Committee are to (i) identify individuals qualified to become Board members; (ii) select, or recommend to the Board, director nominees for each election of directors; (iii) develop and recommend to the Board criteria for selecting qualified director candidates; (iv) consider committee member qualifications, appointment and removal; (v) recommend applicable corporate governance principles, codes of conduct and compliance mechanisms, and (vi) provide oversight in the evaluation of the Board and each committee. The Nominating and Governance Committee held six meetings during the fiscal year ended December 31, 2005.

      The Nominating and Governance Committee’s goal is to assemble a Board of Directors that brings a variety of perspectives and skills derived from high quality business and professional experience. There are no

stated minimum criteria for director nominees, but the Nominating and Governance Committee believes that at least one member of the Board meet the criteria for an “audit committee financial expert” as defined by SEC rules, and that a majority of the members of the Board meet the definition of “independent director” under the rules of the American Stock Exchange. The Nominating and Governance Committee also believes it appropriate for certain key members of management to participate as members of the Board.

      When considering whether to recommend any candidate for inclusion in the Board’s slate of recommended director nominees, including candidates recommended by our stockholders, the Nominating and Governance Committee will review the candidate’s integrity, business acumen, age, experience, commitment, diligence, conflicts of interest, existing time commitments and the ability to act in the interests of all stockholders. Once a potential qualified candidate is identified, one or more members of the Nominating and Governance Committee will interview that candidate. The committee may also ask the candidate to meet with non-committee members of the Board and/or members of management and, if the committee believes a candidate would be a valuable addition to the Board, it will recommend that candidate to the full Board.

      Pursuant to the terms of its charter, the Nominating and Governance Committee will consider qualified director candidates suggested by our stockholders. Stockholders may recommend individuals for the Nominating and Governance Committee to consider as potential director candidates by submitting the candidate’s name, contact information and biographical information in writing to the “Halozyme Nominating and Governance Committee” c/o Corporate Secretary, 11588 Sorrento Valley Road, Suite 17, San Diego, California 92121. The biographical information and background materials will be forwarded to the Nominating and Governance Committee for its review and consideration. The committee’s review of candidates identified by our stockholders is essentially identical to the review process for candidates identified by the committee. The Nominating and Governance Committee will review periodically whether a more formal policy regarding stockholder nominations should be adopted. In addition to the process discussed above regarding the consideration of the Nominating and Governance Committee of candidates suggested by our stockholders, our Bylaws contain provisions that address the process by which a stockholder may nominate an individual to stand for election to our Board at our annual meeting of stockholders.

Communications with Directors

      Any stockholder who desires to contact any members of our Board of Directors may do so by writing to: Board of Directors, c/o Corporate Secretary, 11588 Sorrento Valley Road, Suite 17, San Diego, California 92121. Communications received in writing are distributed to the Chairman of the Board or the other members of the Board as appropriate depending on the facts and circumstances outlined in the communication received. Alternatively, any stockholder who desires to contact an independent member of our Board of Directors directly, may contact the Chairman of our Board of Directors, Kenneth J. Kelley, electronically by sending an email to the following address: kkelley@halozyme.com.

Director Attendance at Annual Meetings

      Although we do not have a formal policy regarding attendance by members of the Board at our annual meeting of stockholders, we encourage directors to attend. Drs. Lim, Frost and Engler attended our annual meeting of stockholders in 2005. Mr. Thornton was not a member of the Board at the time of this meeting.

Committee Charters

      The Board has adopted a charter for each of the committees described above and links to these charters are available on our website, www.halozyme.com.

Code of Ethics

      The Board has adopted a Code of Conduct and Ethics that applies to all of our employees, officers and directors. A copy of our Code of Conduct and Ethics is currently available on our website, www.halozyme.com. Please note that the information on our website is not incorporated by reference in this Proxy Statement.

PROPOSAL NO. 2

APPROVAL OF AMENDMENTS TO THE AMENDED AND RESTATED ARTICLES OF INCORPORATION TO INCREASE THE AUTHORIZED NUMBER OF SHARES OF COMMON STOCK FROM 100,000,000 TO 150,000,000 AND TO ELIMINATE OUTDATED REFERENCES TO FORMER DIRECTORS

      The Board has adopted, subject to stockholder approval, amendments to our Amended and Restated Articles of Incorporation (the “Articles”) to increase our authorized number of shares of Common Stock from 100,000,000 to 150,000,000 and to remove outdated references to individuals that no longer serve on the Board.

Background of Proposal

      Under Nevada law, we may only issue shares of Common Stock to the extent such shares have been authorized for issuance under the Articles. The Articles currently authorize the issuance of up to 100,000,000 shares of Common Stock, each having a par value of one-tenth of one cent ($0.001). However, as of March 1, 2006, approximately 60.3 million shares of Common Stock were issued and outstanding and approximately 20.0 million unissued shares were reserved for issuance (i) under our equity compensation plans and (ii) upon exercise of outstanding warrants, leaving approximately 19.7 million shares of Common Stock unissued and unreserved. In order to ensure sufficient shares of Common Stock will be available for issuance by us, the Board of Directors has approved, subject to stockholder approval, amendments to our Articles to increase the number of shares of such Common Stock authorized for issuance from 100,000,000 to 150,000,000.

      The Articles also currently list the five members of the Board as of March 11, 2004 (the date that the Articles were filed). The composition and size of the Board has changed since that time and the Board has approved, subject to stockholder approval, amendments to our Articles that remove references to specific Board size as well as the names of particular individuals on the Board.

Purpose and Effect of the Amendments

      The principal purpose of the proposed amendment to the Articles is to authorize additional shares of Common Stock, which will be available in the event the Board determines that it is necessary or appropriate to permit future stock splits in the form of stock dividends, to raise additional capital through the sale of equity securities, to acquire another company or its assets, to establish strategic relationships with corporate partners, to provide equity incentives to employees and officers or for other corporate purposes. The availability of additional shares of Common Stock is particularly important in the event that the Board needs to undertake any of the foregoing actions on an expedited basis and thus to avoid the time and expense of seeking stockholder approval in connection with the contemplated issuance of Common Stock. We do not currently have any plan, commitment, arrangement, understanding or agreement, either oral or written, regarding the issuance of these additional shares of Common Stock. If the amendments are approved by the stockholders, the Board does not intend to solicit further stockholder approval prior to the issuance of any additional shares of Common Stock, except as may be required by applicable law.

      The increase in authorized common stock will not have any immediate effect on the rights of existing stockholders. However, the Board will have the authority to issue authorized Common Stock without requiring future stockholder approval of such issuances, except as may be required by applicable law. To the extent that additional authorized shares are issued in the future, they may decrease the existing stockholders’ percentage equity ownership and, depending on the price at which they are issued, could be dilutive to the existing stockholders. The holders of Common Stock have no preemptive rights and the Board has no plans to grant such rights with respect to any such shares.

      The increase in the authorized number of shares of Common Stock and the subsequent issuance of such shares could have the effect of delaying or preventing a change in control of Halozyme without further action by the stockholders. Shares of authorized and unissued Common Stock could, within the limits imposed by applicable law, be issued in one or more transactions which would make a change in control of Halozyme more difficult, and therefore less likely. Any such issuance of additional stock could have the effect of diluting

the earnings per share and book value per share of outstanding shares of common stock and such additional shares could be used to dilute the stock ownership or voting rights of a person seeking to obtain control of Halozyme.

      The Board is not currently aware of any attempt to take over or acquire Halozyme. While it may be deemed to have potential anti-takeover effects, the proposed amendments to increase the authorized Common Stock are not prompted by any specific effort or takeover threat currently perceived by management.

      If this proposal is approved by the stockholders, the first paragraph of Article IV of the Articles will be amended to read in its entirety substantially as follows:

      In addition, the Articles currently list the five Board members that were sitting on March 11, 2004 (the date that the Articles were filed with the Nevada Secretary of State). Since that time the size and composition of the Board has changed as certain directors left the Board and others were added. If this proposal is approved by the stockholders, Article V of the Articles will be amended to read in its entirety substantially as follows:

      These proposed amendments to the Articles are set forth in Appendix A. The additional shares of Common Stock to be authorized pursuant to the proposed amendment will be of the same class of common stock as is currently authorized under the Articles. If approved, this proposal will become effective upon the filing of Amended and Restated Articles of Incorporation with the Secretary of State of the State of Nevada containing substantially these amendments, which Halozyme will do promptly after the annual meeting.

Required Vote and Board of Directors Recommendation

      Approval of this proposal requires the affirmative vote of the holders of a majority of the shares of our Common Stock outstanding on the Record Date. Abstentions and broker non-votes will be counted as present for purposes of determining if a quorum is present, but will have the same effect as a negative vote on the outcome of this proposal.

      The Board believes that the proposed amendments to the Articles are in the best interests of Halozyme and its stockholders for the reasons stated above. Therefore, the Board unanimously recommends a vote “FOR” amendments to our Amended and Restated Articles of Incorporation to increase the number of authorized shares of Common Stock from 100,000,000 to 150,000,000 and to eliminate references to former directors.

PROPOSAL NO. 3

APPROVAL OF THE HALOZYME THERAPEUTICS, INC.

2005 OUTSIDE DIRECTORS’ STOCK PLAN

      The Board of Directors adopted the Halozyme Therapeutics, Inc. 2005 Outside Director’s Stock Plan (the “Director Plan”), in June 2005.

      The Board believes that the Company must offer competitive compensation, including an equity incentive program, if it is to continue to successfully attract and retain the best possible directors. The Board expects that the Director Plan will be an important factor in attracting and retaining the high caliber directors essential

to our success, in motivating such directors to strive to increase the value of the Company for its stockholders and in aligning the interest of the directors and the stockholders.

Summary of the Director Plan

      The following is a summary of the material terms of the Director Plan. It is qualified in its entirety by the specific language of the Director Plan, which is available to any stockholder upon request.

      General. The Director Plan provides to members of the Board of Directors who are not employees of the Company or of any subsidiary or parent of the Company (“Outside Directors”) the (i) automatic grant of nonstatutory stock options, and (ii) automatic grant of restricted stock. The Director Plan is intended to qualify as a “formula plan” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934.

      Authorized Shares. A maximum of 500,000 of the authorized but unissued or reacquired shares of our Common Stock may be issued under the Director Plan. If any award expires, lapses or otherwise terminates for any reason without having been exercised or settled in full, or if shares subject to forfeiture or repurchase are forfeited or repurchased by the Company, any such shares that are reacquired or subject to such a terminated award will again become available for issuance under the Director Plan. If shares are surrendered in satisfaction of tax obligations, such shares shall not be deemed to be issued under the Director Plan. Upon any stock dividend, stock split, reverse stock split, recapitalization or similar change in our capital structure, appropriate adjustments will be made to the shares subject to the Director Plan, to the terms applicable to any automatic grant of awards described below, and to all outstanding awards.

      Administration. The Director Plan is intended to operate automatically without discretionary administration. To the extent administration is necessary, it will be performed by the Board or a committee of the Board. (For purposes of this discussion, the term “Board” refers to either the Board of Directors or such committee.) The Director Plan will be administered in a manner intended to permit awards to be exempt from Section 16(b) of the Securities Exchange Act of 1934 in accordance with Rule 16b-3 thereunder. The Board will approve forms of award agreements for use under the Director Plan, determine the terms and conditions of awards consistent with the requirements of the Director Plan, and construe and interpret the terms of the Director Plan and awards granted under it. However, the Board has no discretion to select the Outside Directors who are granted awards under the Director Plan.

      Eligibility. Only directors of the Company who are Outside Directors at the time of grant are eligible to participate in the Director Plan. Currently, four Outside Directors are eligible for the Director Plan.

      Automatic Grant of Stock Options. Stock options will be granted automatically under the Director Plan. Each person who first becomes an Outside Director on or after the Director Plan’s adoption in June 2005 shall be granted on the date he or she becomes an Outside Director an option (an “Initial Option”) for ten thousand (10,000) shares of Common Stock. In addition, following stockholder approval of the Director Plan each Outside Director who has served on the Board for at least six (6) full months prior to an annual meeting of the stockholders shall be granted an Option (“Annual Option”) to purchase ten thousand (10,000) shares immediately following such annual meeting.

      Terms and Conditions of Stock Options. Each Initial Option and Annual Option granted under the Director Plan will be evidenced by a written agreement specifying the number of shares subject to the option and the other terms and conditions of the option, consistent with the provisions of the Director Plan. The per-share exercise price for each Option will be equal to the fair market value of a share of our Common Stock on the date of grant. Generally, the fair market value of the Common Stock is the closing price per share on the date of grant as quoted by the national or regional securities exchange or market system on which the Common Stock is listed. The closing price of our Common Stock as reported on the American Stock Exchange on March 16, 2006 was $3.39 per share.

      The Director Plan provides that the option exercise price may be paid in cash, by check, by tender or attestation of previously owned shares, by assignment of the proceeds of a sale with respect to some or all of the shares acquired upon the exercise or by any other legal means approved by the Board.

      Subject to stockholder approval of the Director Plan, Initial Options will become vested and exercisable in full on the later of the date six (6) months from the grant date or the next annual meeting following the grant date. Annual Options will become vested and exercisable in full on the date immediately preceding the annual meeting following the grant date. Option vesting is subject to the Outside Director’s continuous service to the Company. Unless earlier terminated under the terms of the Director Plan or the option agreement, each option will remain exercisable for ten (10) years after the date of grant. An option may be transferred or assigned to the extent permitted by the Board and set forth in the option agreement.

      Automatic Grant of Restricted Stock. Awards of restricted stock will be granted automatically under the Director Plan. Initial Grants and Annual Grants of restricted stock covering fifteen thousand (15,000) shares each shall be granted on the same schedule and on the same basis as Initial Options and Annual Options.

      Terms and Conditions of Restricted Stock. Each award of restricted stock granted under the Director Plan will be evidenced by a written agreement specifying the number of shares subject to the award and the other terms and conditions of the award, consistent with the provisions of the Director Plan.

      Subject to stockholder approval of the Director Plan, Initial Grants of restricted stock vest in full on the first day the holder may trade Company Stock in compliance with the insider trading policy of the Company following the later of (a) the six month anniversary of the grant date, or (b) the first annual meeting of stockholders following the grant date. Annual Grants of restricted stock vest in full on the first day the holder may trade Company stock in compliance with the Company’s insider trading policy following the date immediately preceding the first annual meeting of stockholders following the grant date.

      Change in Control. If a change in control (as defined in the Director Plan) occurs, all stock options and restricted stock shall be 100% vested prior to the effective date of any change in control. As a result of such a change in control, the surviving, continuing, successor or purchasing corporation or parent corporation thereof may either assume all outstanding awards or substitute new awards having an equivalent value.

      Termination or Amendment. The Director Plan has a term of 10 years. The Director Plan shall continue in effect until the end of the term or until the earlier of its termination by the Board or the date on which all of the shares of Common Stock available for issuance under the Director Plan have been issued and all restrictions on such shares under the terms of the Director Plan have lapsed. The Board may terminate or amend the Director Plan at any time, provided that no amendment may be made without stockholder approval if the Board deems such approval necessary for compliance with any applicable tax or securities law or other regulatory requirements, including the requirements of any stock exchange or market system on which the Common Stock of the Company is then listed. No termination or amendment may affect any outstanding award unless expressly provided by the Board, and, in any event, may not adversely affect an outstanding award without the consent of the Outside Director unless necessary to comply with any applicable law, regulation or rule.

Summary of U.S. Federal Income Tax Consequences

      The following summary is intended only as a general guide to the U.S. federal income tax consequences of participation in the Director Plan and does not attempt to describe all possible federal or other tax consequences of such participation or tax consequences based on particular circumstances.

      Nonstatutory Stock Options. All stock options shall be nonstatutory stock options having no special tax status. An Outside Director generally recognizes no taxable income upon receipt of such an option. Upon exercising a nonstatutory stock option, the Outside Director normally recognizes ordinary income equal to the difference between the exercise price paid and the fair market value of the shares on the date when the option is exercised or such later date as the shares become vested and free of any restrictions on transfer (the later of such dates being referred to as the “determination date”). Upon the sale of stock acquired by the exercise of a nonstatutory stock option, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the determination date, will be taxed as capital gain or loss. The Company generally should be entitled to a tax deduction equal to the amount of ordinary income recognized by the Outside

Director as a result of the exercise of a nonstatutory stock option, except to the extent such deduction is limited by applicable provisions of the Internal Revenue Code.

      Restricted Stock. Acquisitions of restricted stock receive tax treatment that is similar to that of exercises of nonstatutory stock options. An Outside Director acquiring restricted stock normally recognizes ordinary income equal to the difference between the amount, if any, the Outside Director paid for the restricted stock and the fair market value of the shares on the determination date. The Outside Director may elect, pursuant to Section 83(b) of the Internal Revenue Code, to treat the acquisition date as the determination date by filing an election with the Internal Revenue Service. Upon the sale of restricted stock, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the determination date, will be taxed as capital gain or loss. The Company generally should be entitled to a tax deduction equal to the amount of ordinary income recognized by the Outside Director as a result of the acquisition of restricted stock, except to the extent such deduction is limited by applicable provisions of the Internal Revenue Code.

New Plan Benefits

      Only Outside Directors are eligible to participate in the Director Plan. 40,000 shares of our Common Stock underlying the automatic grants of stock options and 75,000 shares of restricted stock will be received under the Director Plan during the 2006 fiscal year by the Outside Directors, assuming no new Outside Directors not currently anticipated join the Board.

Vote Required and Board of Directors Recommendation

      Approval of this proposal would require the affirmative vote of a majority of the votes cast affirmatively or negatively on the proposal at the annual meeting of stockholders, as well as the presence of a quorum representing a majority of all outstanding shares of common stock of the Company, either in person or by proxy. Abstentions and broker non-votes would be counted for purposes of determining the presence of a quorum but otherwise would not have any effect on the outcome of the proposal.

      The Board believes that the adoption of the Director Stock Plan is in the best interests of Halozyme and its stockholders for the reasons stated above. Therefore, the Board unanimously recommends a vote “FOR” approval of the 2005 Stock Plan.

PROPOSAL NO. 4

APPROVAL OF THE HALOZYME THERAPEUTICS, INC.

2006 STOCK PLAN

      In March 2006, the Board of Directors adopted, subject to stockholder approval, the Company’s 2006 Stock Plan (the “2006 Plan”). The 2006 Plan has a share reserve of 2,000,000 shares. As of March 31, 2006, 8,599,833 shares were subject to options under the Company’s existing stock option plans and 2,642,201 shares remained eligible for grant under those plans.

      The Company believes that appropriate equity incentives are critical to attracting and retaining the best employees in its industry. The approval of this proposal will enable the Company to continue to provide such incentives.

      The Board has full discretion to determine the number of awards to be granted to participants under the 2006 Plan, subject to an annual limitation on the total number of awards that may be granted to any employee. Prior to the Annual Meeting, the Company will not grant any awards under the 2006 Plan.

Summary of the 2006 Plan

      The following is a summary of the material terms of the 2006 Plan. It is qualified in its entirety by the specific language of the 2006 Plan, a copy of which is available to any stockholder upon request.

      General. The 2006 Plan provides for the grant of incentive and nonstatutory stock options as well as stock appreciation rights, restricted stock, restricted stock units, performance units and shares and other stock-based awards. Incentive stock options granted under the 2006 Plan are intended to qualify as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). Nonstatutory stock options granted under the 2006 Plan are not intended to qualify as incentive stock options under the Code.

      Purpose. The purpose of the 2006 Plan is to advance the interests of the Company and its stockholders by providing an incentive to attract and retain persons eligible to receive options under the 2006 Plan and by motivating such persons to contribute to the growth and profitability of the Company.

      Administration. The 2006 Plan is administered by the Board of Directors and its designees. The Board has the power to construe and interpret the 2006 Plan and, subject to the provisions of the 2006 Plan, to determine the persons to whom and the dates on which awards will be granted, the number of shares to be subject to each award, the time or times during the term of each award within which all or a portion of such award may be exercised, the exercise price, the type of consideration to be paid upon exercise of an award, and other terms of the award. The Board of Directors is authorized to delegate administration of the 2006 Plan to a committee of outside directors. The Board has delegated administration of the 2006 Plan to the Compensation Committee of the Board. As used herein with respect to the 2006 Plan, the “Board” refers to the Compensation Committee, as well as to the Board of Directors itself.

      Stock Subject to the 2006 Plan. The share reserve under the 2006 Plan will be equal to 2,000,000 shares. If awards granted under the 2006 Plan expire, are cancelled or otherwise terminate without being exercised, the shares of Common Stock subject to such expired, cancelled or terminated awards will then be available for grant under the 2006 Plan. In addition, to the extent (a) shares are surrendered in exercise of awards or payment of tax, or (b) awards are settled in cash, such shares will not be deemed to be issued under the Plan.

      In general, no more than 2,000,000 shares may be issued under the 2006 Plan pursuant to restricted stock awards, restricted stock unit awards and performance awards.

      Eligibility. Awards other than incentive stock options generally may be granted only to employees, directors and consultants of the Company, or certain related entities or designated affiliates. An incentive stock option can only be granted to a person who, on the effective date of grant, is an employee of the Company, a parent corporation or a subsidiary corporation. As of March 31, 2006, approximately 34 persons would have been eligible to receive grants under the 2006 Plan.

      No incentive stock options may be granted under the 2006 Plan to any person who, at the time of the grant, owns (or is deemed to own) stock possessing more than 10% of the total combined voting power of the Company, or any of its parent or subsidiary corporations, unless the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and the term of the option does not exceed 5 years from the date of grant. The aggregate fair market value, determined at the time of grant, of the shares of Common Stock with respect to which incentive stock options granted under the 2006 Plan are exercisable for the first time by an optionee during any calendar year (under all such plans of the Company and its parent and subsidiary corporations) may not exceed $100,000. In order to permit awards to qualify as “performance based compensation” under Code Section 162(m) no employee may be granted awards under the 2006 Plan in excess of the following in each fiscal year of the Company:

Options and Stock Appreciation Rights

      The following is a description of the general terms of options and stock appreciation rights under the 2006 Plan. Individual grants may have terms that differ from those described below.

      Exercise Price; Payment. The exercise price of incentive stock options under the 2001 Option Plan may not be less than the fair market value of the Common Stock subject to the option on the date of the option grant, and in some cases (see “Eligibility” above), may not be less than 110% of such fair market value. The exercise price of nonstatutory stock options and stock appreciation rights may not be less than the fair market value of the stock subject to the award on the date of the option grant. On March 16, 2006, the closing price of the Company’s Common Stock as reported on the American Stock Exchange was $3.39 per share. The exercise price of options granted under the 2006 Plan must be paid: (i) in cash, by check or cash equivalent, (ii) by tender to the Company, or attestation to the ownership of shares of Common Stock of the Company owned by the optionee having a fair market value not less than the exercise price, (iii) for optionees who are employees, in the Company’s sole and absolute discretion, by delivery of a promissory note, (iv) in any other form of legal consideration acceptable to the Board, or (v) any combination of the above.

      No Repricing. The 2006 Plan does not permit the Company to lower the exercise price of options or stock appreciation rights or to exchange options or stock appreciation rights for awards with a lower exercise price without further stockholder approval.

      Exercise. Options and stock appreciation rights granted under the 2006 Plan may become exercisable (“vest”) in cumulative increments as determined by the Board provided that the holder’s employment by, or service as a director or consultant to the Company or certain related entities or designated affiliates (“service”) continues from the date of grant until the applicable vesting date. Shares covered by awards granted under the 2006 Plan may be subject to different vesting terms. The Board has the power to accelerate the time during which an award may be exercised.

      Term. The maximum term of options and stock appreciation rights under the 2006 Plan is ten years, except that in certain cases (see “Eligibility” above) the maximum term is five years. The 2006 Plan provides for earlier termination of an award due to the holder’s cessation of service.

      Restrictions on Transfer. Incentive stock options granted under the 2006 Plan may not be transferred except by will or by the laws of descent and distribution, and may be exercised during the lifetime of the person to whom the option is granted only by such person. A nonstatutory stock option or stock appreciation right is not transferable in any manner other than (i) by will or by the laws of descent and distribution, (ii) by written designation of a beneficiary taking effect upon the death of the optionee, (iii) by delivering written notice to the Company that the optionee will be gifting to certain family members or other specific entities controlled by or for the benefit of such family members, and such other transferees as the Board may approve.

Restricted Stock Units

      The Board may grant restricted stock units under the 2006 Plan that represent a right to receive shares of our common stock at a future date determined in accordance with the participant’s award agreement. No monetary payment is required for receipt of restricted stock units or the shares issued in settlement of the award, the consideration for which is furnished in the form of the participant’s services to the company. The Board may grant restricted stock unit awards subject to the attainment of one or more performance goals similar to those described below in connection with performance awards, or may make the awards subject to vesting conditions similar to those applicable to restricted stock awards. Unless otherwise provided by the Board, a participant will forfeit any restricted stock units which have not vested prior to the participant’s termination of service. Participants have no voting rights or rights to receive cash dividends with respect to restricted stock unit awards until shares of common stock are issued in settlement of such awards. However, the Board may grant restricted stock units that entitle their holders to receive dividend equivalents, which are rights to receive additional restricted stock units for a number of shares whose value is equal to any cash dividends we pay.

Restricted Stock Awards

      The Board may grant restricted stock awards under the 2006 Plan either in the form of a restricted stock purchase right, giving a participant an immediate right to purchase common stock, or in the form of a restricted stock bonus, for which the participant furnishes consideration in the form of services to the company. The Board determines the purchase price payable under restricted stock purchase awards, which may be less than the then current fair market value of our common stock. Restricted stock awards may be subject to vesting conditions based on such service or performance criteria as the Board specifies, including the attainment of one or more performance goals similar to those described below in connection with performance awards. Shares acquired pursuant to a restricted stock award may not be transferred by the participant until vested. Unless otherwise provided by the Board, a participant will forfeit any shares of restricted stock as to which the restrictions have not lapsed prior to the participant’s termination of service. Participants holding restricted stock will generally have the right to vote the shares and to receive any dividends paid, except that dividends or other distributions paid in shares will be subject to the same restrictions as the original award.

Performance Awards

      The Board may grant performance awards subject to such conditions and the attainment of such performance goals over such periods as the determines in writing and sets forth in a written agreement between the company and the participant. To the extent compliance with Section 162(m) of the Code is desired, a committee comprised solely of “outside directors” under Section 162(m) shall act with respect to performance awards, and “Board” as used in this section shall mean this committee. These awards may be designated as performance shares or performance units. Performance shares and performance units are unfunded bookkeeping entries generally having initial values, respectively, equal to the fair market value determined on the grant date of a share of common stock and a value set by the Board. Performance awards will specify a predetermined amount of performance shares or performance units that may be earned by the participant to the extent that one or more predetermined performance goals are attained within a predetermined performance period. To the extent earned, performance awards may be settled in cash, shares of common stock (including shares of restricted stock) or any combination thereof.

      Prior to the beginning of the applicable performance period or such later date as permitted under Section 162(m) of the Code, the Board will establish one or more performance goals applicable to the award. Performance goals will be based on the attainment of specified target levels with respect to one or more measures of business or financial performance of the company and each subsidiary corporation consolidated with the company for financial reporting purposes, or such division or business unit of the company as may be selected by the Board. The Board, in its discretion, may base performance goals on one or more of the following such measures: sales revenue, gross margin, operating margin, operating income, pre-tax profit, earnings before stock-based compensation expense, interest, taxes, depreciation and amortization, net income, expenses, the market price of our common stock, earnings per share, return on stockholder equity, return on capital, return on net assets, economic value added, market share, customer service, customer satisfaction, safety, total stockholder return, free cash flow, net operating income, operating cash flow, return on investment, employee satisfaction, employee retention, balance of cash, cash equivalents and marketable securities, product development, research and development expenses, completion of an identified special project, completion of a joint venture or other corporate transaction, or other measures as determined by the Board. The target levels with respect to these performance measures may be expressed on an absolute basis or relative to a standard specified by the Board. The degree of attainment of performance measures will be calculated in accordance with generally accepted accounting principles, but prior to the accrual or payment of any performance award for the same performance period, and, according to criteria established by the Board, excluding the effect (whether positive or negative) of changes in accounting standards or any extraordinary, unusual or nonrecurring item occurring after the establishment of the performance goals applicable to a performance award.

      Following completion of the applicable performance period, the Board will certify in writing the extent to which the applicable performance goals have been attained and the resulting value to be paid to the participant. The Board retains the discretion to eliminate or reduce, but not increase, the amount that would

otherwise be payable on the basis of the performance goals attained to a participant who is a “covered employee” within the meaning of Section 162(m) of the Code. However, no such reduction may increase the amount paid to any other participant. The Board may make positive or negative adjustments to performance award payments to participants other than covered employees to reflect the participant’s individual job performance or other factors determined by the Board. In its discretion, the Board may provide for the payment to a participant awarded performance shares of dividend equivalents with respect to cash dividends paid on the company’s common stock. The Board may provide for performance award payments in lump sums or installments. If any payment is to be made on a deferred basis, the Board may provide for the payment of dividend equivalents or interest during the deferral period.

      Unless otherwise provided by the Board, if a participant’s service terminates due to the participant’s death or disability prior to completion of the applicable performance period, the final award value will be determined at the end of the performance period on the basis of the performance goals attained during the entire performance period but will be prorated for the number of months of the participant’s service during the performance period. If a participant’s service terminates prior to completion of the applicable performance period for any other reason, the 2006 Plan provides that, unless otherwise determined by the Board, the performance award will be forfeited. No performance award may be sold or transferred other than by will or the laws of descent and distribution prior to the end of the applicable performance period.

Deferred Compensation Awards

      The 2006 Plan authorizes the Board to establish a deferred compensation award program. If and when implemented, participants designated by the Board who are officers, directors or members of a select group of highly compensated employees may elect to receive, in lieu of compensation otherwise payable in cash or in lieu of cash or shares of common stock issuable upon the exercise or settlement of stock options, stock appreciation rights or performance share or performance unit awards, an award of deferred stock units. Each such stock unit represents a right to receive one share of our common stock at a future date determined in accordance with the participant’s award agreement. Deferred stock units are fully vested upon grant and will be settled by distribution to the participant of a number of whole shares of common stock equal to the number of stock units subject to the award as soon as practicable following the earlier of the date on which the participant’s service terminates or a settlement date elected by the participant at the time of his or her election to receive the deferred stock unit award. Participants are not required to pay any additional consideration in connection with the settlement of deferred stock units. A holder of deferred stock units has no voting rights or other rights as a stockholder until shares of common stock are issued to the participant in settlement of the stock units. However, participants holding deferred stock units will be entitled to receive dividend equivalents with respect to any payment of cash dividends on an equivalent number of shares of common stock. Such dividend equivalents will be credited in the form of additional whole and fractional stock units determined in accordance with a method specified by the Board in the participant’s award agreement. Prior to settlement, deferred stock units may not be assigned or transferred other than by will or the laws of descent and distribution.

Other Stock-Based Awards

      The Plan permits the Board to grant other awards based on the Company’s stock or on dividends on the Company’s stock.

Effect of Certain Corporate Events

      In the event of any stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification or similar change in the capital structure of the Company, appropriate adjustments will be made in the number and class of shares subject to the 2006 Plan and to any outstanding awards, in the aggregate and Section 162(m) per employee grant limits (see “Federal Income Tax Information — Potential Limitation on Company Deductions,” below), and in the exercise price per share of any outstanding awards. Any fractional share resulting from an adjustment will be rounded down to the nearest whole number, and at

no time will the exercise price of any option or stock appreciation right be decreased to an amount less than par value of the stock subject to the award.

      If a change in control occurs, the surviving, continuing, successor or purchasing corporation or parent corporation thereof may either assume the Company’s rights and obligations under the outstanding awards or substitute substantially equivalent awards for such corporation’s stock. Awards that are not assumed, replaced or exercised prior to the change in control will terminate. The Board may grant awards that will accelerate in connection with a change in control. The acceleration of an award in the event of an acquisition or similar corporate event may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain control of the Company.

Duration, Amendment and Termination

      The Board may amend or terminate the 2006 Plan at any time. If not earlier terminated, the 2006 Plan will expire on the tenth anniversary of stockholder approval.

      The Board may also amend the 2006 Plan at any time or from time to time. However, no amendment authorized by the Board will be effective unless approved by the stockholders of the Company if the amendment would: (i) increase the number of shares reserved for options under the 2006 Plan; (ii) change the class of persons eligible to receive incentive stock options; or (iii) modify the 2006 Plan in any other way if such modification requires stockholder approval under applicable law, regulation or rule.

Specific Grants

      Awards under the 2006 Plan are discretionary. Accordingly, it is not possible to determine the number of awards that may be granted under the 2006 Plan to specific individuals.

Federal Income Tax Information

      Incentive Stock Options. An optionee recognizes no taxable income for regular income tax purposes as the result of the grant or exercise of an incentive stock option. Optionees who do not dispose of their shares for two years following the date the incentive stock option was granted or within one year following the exercise of the option will normally recognize a long-term capital gain or loss equal to the difference, if any, between the sale price and the purchase price of the shares. If an optionee satisfies both such holding periods upon a sale of the shares, the Company will not be entitled to any deduction for federal income tax purposes. If an optionee disposes of shares either within two years after the date of grant or within one year from the date of exercise (referred to as a “disqualifying disposition”), the difference between the fair market value of the shares on the exercise date and the option exercise price (not to exceed the gain realized on the sale if the disposition is a transaction with respect to which a loss, if sustained, would be recognized) will be taxed as ordinary income at the time of disposition. Any gain in excess of that amount will be a capital gain. If a loss is recognized, there will be no ordinary income, and such loss will be a capital loss. A capital gain or loss will be long-term if the optionee’s holding period is more than 12 months. Any ordinary income recognized by the optionee upon the disqualifying disposition of the shares generally should be deductible by the Company for federal income tax purposes, except to the extent such deduction is limited by applicable provisions of the Code or the regulations thereunder. The difference between the option exercise price and the fair market value of the shares on the exercise date of an incentive stock option is an adjustment in computing the optionee’s alternative minimum taxable income and may be subject to an alternative minimum tax which is paid if such tax exceeds the regular tax for the year. Special rules may apply with respect to certain subsequent sales of the shares in a disqualifying disposition, certain basis adjustments for purposes of computing the alternative minimum taxable income on a subsequent sale of the shares and certain tax credits which may arise with respect to optionees subject to the alternative minimum tax.

      Nonstatutory Stock Options and Stock Appreciation Rights. Nonstatutory stock options and stock appreciation rights have no special tax status. A holder of these awards generally does not recognize taxable income as the result of the grant of such award. Upon exercise of a nonstatutory stock option or stock appreciation right, the holder normally recognizes ordinary income in an amount equal to the difference

between the exercise price and the fair market value of the shares on the exercise date. If the holder is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of stock acquired by the exercise of a nonstatutory stock option or stock appreciation right, any gain or loss, based on the difference between the sale price and the fair market value on the exercise date, will be taxed as capital gain or loss. A capital gain or loss will be long-term if the holding period of the shares is more than 12 months. The Company generally should be entitled to a deduction equal to the amount of ordinary income recognized by the optionee as a result of the exercise of a nonstatutory stock option or stock appreciation right, except to the extent such deduction is limited by applicable provisions of the Code or the regulations thereunder. No tax deduction is available to the Company with respect to the grant of a nonstatutory stock option or stock appreciation right or the sale of the stock acquired pursuant to such grant.

      Restricted Stock. A participant acquiring restricted stock generally will recognize ordinary income equal to the fair market value of the shares on the “determination date.” The “determination date” is the date on which the participant acquires the shares unless the shares are subject to a substantial risk of forfeiture and are not transferable, in which case the determination date is the earlier of (i) the date on which the shares become transferable or (ii) the date on which the shares are no longer subject to a substantial risk of forfeiture. If the determination date is after the date on which the participant acquires the shares, the participant may elect, pursuant to Section 83(b) of the Code, to have the date of acquisition be the determination date by filing an election with the Internal Revenue Service no later than 30 days after the date on which the shares are acquired. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of shares acquired pursuant to a restricted stock award, any gain or loss, based on the difference between the sale price and the fair market value on the determination date, will be taxed as capital gain or loss. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant on the determination date, except to the extent such deduction is limited by applicable provisions of the Code.

      Performance and Restricted Stock Unit Awards. A participant generally will recognize no income upon the receipt of a performance share, performance unit or restricted stock unit award. Upon the settlement of such awards, participants normally will recognize ordinary income in the year of receipt in an amount equal to the cash received and the fair market value of any substantially vested shares received. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. If the participant receives shares of restricted stock, the participant generally will be taxed in the same manner as described above (see discussion under “Restricted Stock”). Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value on the “determination date” (as defined above under “Restricted Stock”), will be taxed as capital gain or loss. The company generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant on the determination date, except to the extent such deduction is limited by applicable provisions of the Code.

      Deferred Compensation Awards. A participant generally will recognize no income upon the receipt of deferred compensation awards. Upon the settlement of the awards, the participant normally will recognize ordinary income in the year of settlement in an amount equal to the fair market value of the shares received. Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the date they are transferred to the participant, will be taxed as capital gain or loss. The Company generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant, except to the extent such deduction is limited by applicable provisions of the Internal Revenue Code.

      Potential Limitation on Company Deductions. Code Section 162(m) denies a deduction to the Company for compensation paid to certain employees in a taxable year to the extent that compensation exceeds $1 million for a covered employee. It is possible that compensation attributable to stock options, when combined with all other types of compensation received by a covered employee from the Company, may cause this limitation to be exceeded in any particular year. Certain kinds of compensation, including qualified “performance-based compensation,” are disregarded for purposes of the deduction limitation. In accordance with applicable regulations issued under Section 162(m), compensation attributable to stock options and stock appreciation rights will qualify as performance-based compensation, provided that: (i) the option plan

contains a per-employee limitation on the number of shares for which options or stock appreciation rights may be granted during a specified period, (ii) the per-employee limitation is approved by the stockholders, (iii) the option is granted by a Compensation Committee comprised solely of “outside directors” (as defined in Section 162(m)) and (iv) the exercise price of the option or right is no less than the fair market value of the stock on the date of grant.

      For the aforementioned reasons, the 2006 Plan provides for an annual per employee limitation as required under Section 162(m) and the Company’s Compensation Committee is comprised solely of outside directors. Accordingly, options or stock appreciation rights granted by the Compensation Committee qualify as performance-based compensation, and the other awards subject to performance goals may qualify.

      Other Tax Consequences. The foregoing discussion is intended to be a general summary only of the federal income tax aspects of awards granted under the 2006 Plan; tax consequences may vary depending on the particular circumstances at hand. In addition, administrative and judicial interpretations of the application of the federal income tax laws are subject to change. Furthermore, no information is given with respect to state or local taxes that may be applicable. Participants in the 2006 Plan who are residents of or are employed in a country other than the United States may be subject to taxation in accordance with the tax laws of that particular country in addition to or in lieu of United States federal income taxes.

Vote Required and Board of Directors Recommendation

      Approval of this proposal would require the affirmative vote of a majority of the votes cast affirmatively or negatively on the proposal at the annual meeting of stockholders, as well as the presence of a quorum representing a majority of all outstanding shares of common stock of the Company, either in person or by proxy. Abstentions and broker non-votes would be counted for purposes of determining the presence of a quorum but otherwise would not have any effect on the outcome of the proposal.

      The Board believes that the adoption of the 2006 Stock Plan is in the best interests of Halozyme and its stockholders for the reasons stated above. Therefore, the Board unanimously recommends a vote “FOR” approval of the 2006 Stock Plan.

PROPOSAL NO. 5

ADJOURNMENT OF THE MEETING, IF NECESSARY, TO SOLICIT ADDITIONAL PROXIES

      Under our Bylaws, any meeting of stockholders, whether or not a quorum is present or has been established, may be adjourned by the affirmative vote of a majority of the shares casting votes that are entitled to vote and are present, in person or by proxy. No new notice need be given of the date, time or place of the adjourned meeting if such date, time or place is announced at the meeting before adjournment, unless the meeting is adjourned to a date more than 60 days after the date fixed for the original meeting or if a new record date is fixed for the adjourned meeting. If the proxy holders determine that an adjournment of the meeting is appropriate for the purpose of soliciting additional proxies in favor of any proposal being submitted at the meeting, such adjournment will be submitted for a stockholder vote under Proposal 5 of the attached Notice of Meeting. We will also use the discretionary authority conferred on our proxy holders by duly executed proxy cards to vote for any other matter as Halozyme determines to be appropriate.

Vote Required and Board of Directors Recommendation

      The affirmative vote of a majority of the votes cast at the meeting, at which a quorum is present, either in person or by proxy, is required to approve this proposal. Abstentions and broker non-votes will each be counted as present for purposes of determining the presence of a quorum, but will not have any effect on the outcome of the proposal.

      The Board believes that the adoption of this proposal is in the best interests of Halozyme and its stockholders. Therefore, the Board unanimously recommends a vote “FOR” adjournment of the meeting, if necessary in the judgment of the proxy holders, to solicit additional proxies in favor of the proposals in this proxy statement.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      We have entered into indemnification agreements with each of our executive officers and directors containing provisions that may require us, among other things, to indemnify those officers and directors against liabilities that may arise by reasons of their status or service as officers or directors. The agreements also provide for Halozyme to advance to the officers and directors expenses that they expect to incur as a result of any proceeding against them as to which they could be indemnified. We also intend to execute such agreements with our future directors and executive officers.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers and directors and persons who beneficially own more than 10% of our Common Stock to file initial reports of beneficial ownership and reports of changes in beneficial ownership with the SEC. Such persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms filed by such person.

      Based solely on our review of such forms furnished to us and written representations from certain reporting persons, we believe that all filing requirements applicable to our executive officers, directors and greater-than-10% stockholders were met.

APPOINTMENT OF INDEPENDENT AUDITORS

      The Audit Committee of the Board of Directors of Halozyme has not yet selected an independent auditor to audit the consolidated financial statements of Halozyme for the fiscal year ending December 31, 2006, as it is still reviewing various independent auditor candidates. Cacciamatta Accountancy Corporation has acted in such capacity since its appointment in fiscal year 2003. A representative of Cacciamatta Accountancy Corporation is expected to be present at the annual meeting and to make a statement. A representative of Cacciamatta Accountancy Corporation is also expected to be available to respond to appropriate questions.

      The following table sets forth the aggregate fees billed to Halozyme for the fiscal years ended December 31, 2005, and December 31, 2004, by Cacciamatta Accountancy Corporation:

      The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by our independent auditors. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services. The independent auditor and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditor in accordance with this pre-approval. The chair of the Audit Committee is also authorized, pursuant to delegated authority, to pre-approve additional services of up to $25,000 per engagement on a case-by-case basis, and such approvals are communicated to the full Audit Committee at its next meeting.

      On March 12, 2004, our Board of Directors voted to replace the independent accountant that had reported on the financial statements for Global Yacht Services, Inc., Hall & Company (“Hall”). We authorized Hall to respond fully to any inquiries from Cacciamatta Accountancy Corporation and to make Hall’s work papers available to Cacciamatta Accountancy Corporation. We did not have any disagreements with Hall nor did Hall’s prior reports contain adverse opinions or disclaimers of opinions. Hall did not make any negative report regarding our internal controls, management or prior financial statements prior to its dismissal.

REPORT OF THE AUDIT COMMITTEE

      The Audit Committee oversees Halozyme’s financial reporting process on behalf of the Board of Directors. The Audit Committee consists of three directors each of whom, in the judgment of the Board, is an “independent director” as defined in the listing standards for The American Stock Exchange. The Audit Committee acts pursuant to a written charter that has been adopted by the Board of Directors.

      Management has the primary responsibility for the financial statements and the reporting process, including internal control systems. Our independent auditor, Cacciamatta Accountancy Corporation, is responsible for expressing an opinion as to the conformity of our audited financial statements with generally accepted accounting principles. The Audit Committee has reviewed and discussed the consolidated financial statements with management and Cacciamatta Accountancy Corporation.

      The Committee has also discussed and reviewed with the auditors all matters required to be disclosed in Statement on Auditing Standards No. 61 (Communication with Audit Committees). The Committee has met with Cacciamatta Accountancy Corporation, with and without management present, to discuss the overall scope of the Cacciamatta Accountancy Corporation audit, the results of its examinations, its evaluations of Halozyme’s internal controls and the overall quality of its financial reporting.

      The Audit Committee has received from the auditors a formal written statement describing all relationships between the auditors and Halozyme that might bear on the auditors’ independence consistent with Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), discussed with the auditors any relationships that may impact their objectivity and independence, and satisfied itself as to the auditors’ independence.

      Based on the review and discussions referred to above, the committee recommended to the Board of Directors that Halozyme’s audited financial statements be included in Halozyme’s Annual Report on Form 10-KSB for the fiscal year ended December 31, 2005.

STOCKHOLDER PROPOSALS TO BE PRESENTED AT NEXT ANNUAL MEETING

      Stockholder proposals may be included in our proxy materials for an annual meeting so long as they are provided to us on a timely basis and satisfy the other conditions set forth in applicable SEC rules. For a stockholder proposal to be included in our proxy materials for the 2007 annual meeting, the proposal must be received at our principal executive offices, addressed to the Secretary, not later than November 30, 2006. Stockholder business that is not intended for inclusion in our proxy materials may be brought before the annual meeting so long as we receive notice of the proposal as specified by our Bylaws, addressed to the Secretary at our principal executive offices, not later than November 30, 2006.

TRANSACTION OF OTHER BUSINESS

      At the date of this Proxy Statement, the Board of Directors knows of no other business that will be conducted at the 2006 annual meeting other than as described in this Proxy Statement. If any other matter or matters are properly brought before the meeting, or any adjournment or postponement of the meeting, it is the intention of the persons named in the accompanying form of proxy to vote the proxy on such matters in accordance with their best judgment.
