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 15, 2007, 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 April 12, 2007.
 
SOLICITATION AND VOTING
 
Voting Securities.  Only stockholders of record as of the close of business on April 4, 2007, will be entitled to vote at the meeting and any adjournment thereof. As of that time, we had 71,531,197 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 each 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 three 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 2007 annual meeting of stockholders we will be electing three Class III directors, while two Class I directors will be elected at the 2008 annual meeting of stockholders and two Class II directors will be elected at the 2009 annual meeting of stockholders. Once elected, directors serve until their respective successors are duly elected and qualified.
 
The Class III nominees recommended by the Board of Directors for election are Robert L. Engler, Gregory I. Frost and Connie L. Matsui. Each of Dr. Engler, Dr. Frost and Ms. Matsui are current members of our Board of Directors and, if elected, they will serve as directors until our annual meeting of stockholders in 2010 and until their successors are elected and qualified. If any 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 three nominees for Class III directors receiving the highest number of votes will be elected as the Class III 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.

CORPORATE GOVERNANCE
 
Director Independence
 
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 both the American Stock Exchange and the Nasdaq Marketplace Rules.
 
Executive Sessions
 
Our independent directors meet in executive session without management present each time the Board holds its regularly scheduled meetings. Mr. Kelley, as chair of the Board of Directors, acts as the presiding director for such executive sessions of independent directors.
 
Board Meetings and Committees
 
The Board of Directors held ten meetings during the fiscal year ended December 31, 2006. The Board of Directors has an Audit Committee, a Compensation Committee and a Nominating and Governance Committee. During the last fiscal year, each director attended at least 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.
 
Audit Committee.
 
The members of the Audit Committee are Kenneth J. Kelley (Chairman), Steven T. Thornton and Connie L. Matsui. Each of the members of the Audit Committee satisfy the independence requirements established by the American Stock Exchange and the Nasdaq Marketplace Rules. Mr. Kelley is an audit committee financial expert, as defined in the rules of the Securities and Exchange Commission. The Audit Committee operates under a written charter that is available on our website at: www.halozyme.com. The Audit Committee conducts an annual review of this charter in addition to an annual review of the committee’s overall performance. 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 nine meetings during the fiscal year ended December 31, 2006.
 
Additional information regarding the Audit Committee is set forth in the Report of the Audit Committee immediately following Proposal No. 2.

Table of Contents

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 American Stock Exchange and the Nasdaq Marketplace Rules. The Compensation Committee operates under a written charter that is available on our website at: www.halozyme.com. The Compensation Committee conducts an annual review of this charter in addition to an annual review of the committee’s overall performance. The primary purpose of the Compensation Committee is to discharge the Board’s responsibilities relating to compensation and benefits of our executive officers. More specifically, 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; recommends stock option grants to executive officers and approves stock option grants to other employees; approves all employment and severance agreements; and reviews the compensation of outside directors for service on the Board of Directors and its committees and recommends changes in compensation for outside directors. The Compensation Committee does not currently engage any consultant related to executive and/or director compensation matters, and instead relies on comparative compensation data from numerous sources to determine appropriate compensation levels. The Compensation Committee held seven meetings during the fiscal year ended December 31, 2006.
 
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 American Stock Exchange and the Nasdaq Marketplace Rules. The Nominating and Governance Committee operates under a written charter that is available on our website at: www.halozyme.com. The Nominating and Governance Committee conducts an annual review of this charter in addition to an annual review of the committee’s overall performance. 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 eight meetings during the fiscal year ended December 31, 2006.
 
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 American Stock Exchange and the Nasdaq Marketplace Rules. 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, multiple 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


5


Table of Contents

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. Directors Engler, Frost and Lim attended our annual meeting of stockholders in 2006. Ms. Matsui was not a member of the Board at the time of this meeting.
 
Code of Conduct and 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.
 
www.halozyme.com
 
Please note that the information on our website is not incorporated by reference in this Proxy Statement.
 
PROPOSAL NO. 2
 
RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS
 
The Audit Committee of the Board of Directors of Halozyme has selected Ernst & Young LLP as independent auditors to audit the consolidated financial statements of Halozyme for the fiscal year ending December 31, 2007. Ernst & Young LLP has acted in such capacity since its appointment on June 28, 2006. A representative of Ernst & Young LLP is expected to be present at the annual meeting, with the opportunity to make a statement if the representative desires to do so, and is expected to be available to respond to appropriate questions.
 
Stockholder ratification of the selection of Ernst & Young LLP as our independent accountants is not required by our Bylaws or otherwise. However, the Board is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent accounting firm at any time during the year if it determines that such a change would be in the best interests of the company and its stockholders.
 
On June 28, 2006, our Audit Committee dismissed our prior independent accountant, Cacciamatta Accountancy Corporation (“Cacciamatta”). Cacciamatta’s reports on our financial statements as of and for the fiscal years ended December 31, 2004 and 2005 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles. During the fiscal years ended December 31, 2004 and 2005, and through June 28, 2006, there were no disagreements with Cacciamatta on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which


6


Table of Contents

disagreements, if not resolved to Cacciamatta’s satisfaction, would have caused Cacciamatta to make reference thereto in its reports on the financial statements for such years. During the period described in the preceding sentence, there were no “reportable events” (as defined in the Securities and Exchange Commission Regulation S-K, Item 304 (a)(1)(v)).
 
We provided Cacciamatta with a copy of the statements set forth in the preceding paragraph and requested that it furnish a letter addressed to the Securities and Exchange Commission stating whether or not it agreed with the above statements. Cacciamatta provided a letter to the Securities and Exchange Commission agreeing with such statements. The following table sets forth the aggregate fees billed to Halozyme for the fiscal year ended December 31, 2006 by Ernst & Young LLP and the aggregate fees billed to Halozyme for the fiscal years ended December 31, 2005 and December 31, 2006 by Cacciamatta:
 
                 
    Fiscal 2006     Fiscal 2005  
 
Audit Fees(1)
  $ 328,670     $ 100,800  
Audit-Related Fees(2)
  $     $  
Tax Fees(3)
  $     $  
All Other Fees(4)
  $     $  
 
 
(1) Audit Fees consist of fees billed for professional services rendered for the audit of the Company’s consolidated annual financial statements and review of the interim consolidated financial statements included in quarterly reports and services that are normally provided by our independent accountant in connection with statutory and regulatory filings or engagements. The Audit Fees for Fiscal 2006 include $26,400 of payments made to Cacciamatta for services provided prior to its dismissal in June of 2006.
 
(2) Audit-Related Fees consist of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under “Audit Fees.”
 
(3) Tax Fees consist of fees billed for professional services rendered for tax compliance, tax advice and tax planning (domestic and international). These services include assistance regarding federal, state and international tax compliance, acquisitions and international tax planning.
 
(4) All Other Fees consist of fees for products and services other than the services reported above.
 
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.

REPORT OF THE AUDIT COMMITTEE
 
The Audit Committee oversees Halozyme’s financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process, including internal control systems. Our independent auditor, Ernst & Young LLP, is responsible for expressing an opinion as to the conformity of our audited financial statements with generally accepted accounting principles. 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 and the Nasdaq Marketplace Rules. The Audit Committee acts pursuant to a written charter that has been adopted by the Board of Directors.
 
The Audit Committee has reviewed and discussed the consolidated financial statements with management and Ernst & Young LLP. 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 Ernst & Young LLP, with and without management present, to discuss the overall scope of the Ernst & Young LLP 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-K for the fiscal year ended December 31, 2006.

EXECUTIVE COMPENSATION
 
Compensation Discussion and Analysis
 
Goals of Compensation Program
 
The primary goals of our Compensation Committee with respect to the compensation of our executive officers are: (i) to attract and retain talented and dedicated executives; (ii) to tie annual and long-term cash and stock incentives to the achievement of specified company and individual performance criteria; and (iii) to align executives’ compensation incentives to achievements that we believe will lead to stockholder value creation. To achieve these goals, the Compensation Committee maintains compensation plans that tie a substantial portion of executives’ overall compensation to the achievement of key operational, clinical and financial goals. The Compensation Committee also evaluates the performance of each individual executive officer against specific individual performance criteria. The Compensation Committee believes that the compensation for our executive officers is comparable with executives in other companies of similar size and stage of development operating in our industry, while taking into account our relative performance and our own strategic goals.
 
We have not retained a compensation consultant to review our policies and procedures with respect to executive compensation; however, we conduct an annual review of the aggregate level of our executive compensation, as well as the mix of elements used to compensate our executive officers. This review is based on a survey of executive compensation paid by similar public biotechnology companies conducted by an independent third party, Radford Biotechnology Survey, as well as compensation data that we obtain from other sources. When comparing our compensation policies against those of other companies, we take into consideration factors such as the size, market capitalization and geographic location of such other companies.
 
Elements of Compensation
 
We currently have a relatively simple compensation structure that is comprised of: (i) base salary; (ii) annual cash and equity incentive awards; and (iii) stock options.
 
Base Salary
 
Base salaries for our executive officers are established based on the scope of their responsibilities, taking into account competitive market compensation paid by other companies for similar positions. Generally, we target salaries for our executive officers near the median of the range of salaries for executives in similar positions with similar responsibilities at comparable companies. Base salaries are reviewed annually, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience as well as the company’s financial position. For 2007, this review occurred in the first quarter and the annual base salaries for the executive officers named in the 2006 Summary Compensation Table below were set at the following levels:
 
         
Name
  2007 Annual Base Salary  
 
Jonathan E. Lim
  $ 360,000  
David A. Ramsay
  $ 235,000  
Gregory I. Frost
  $ 265,000  
Richard C. Yocum
  $ 270,000  
Don A. Kennard
  $ 214,000  
 
Cash and Equity Incentives
 
The Compensation Committee annually establishes a cash and equity bonus structure for our executive officers. Each executive officer is eligible for a maximum cash and equity bonus based upon their accomplishment of specified individual goals as well as the company’s accomplishment of specific performance criteria during the applicable year. The maximum cash bonus amount for each executive officer represents a percentage of that officer’s annual base salary (in 2006, the applicable percentage was 25% for all executive officers other than our Chief Executive Officer who had a percentage of 35%). Maximum equity awards for each executive officer under the incentive plan were derived from a formula that divided (i) the product of a target compensation percentage (75% for our Chief Executive Officer and 40%


9


Table of Contents

for all other executive officers) multiplied by the executive officer’s annual salary by (ii) our stock price on the actual date of grant for the underlying equity award. The individual criteria for specific executive officers varies from position to position, but all executive officers have common company performance goals. The company performance criteria are based upon operational, clinical and financial goals that result from a collaborative process between the Board of Directors and senior management. Historically, if all individual and company performance criteria were not met, executive officers would still be eligible to receive a portion of their respective maximum bonus amounts; provided, however, that if a minimum amount of either individual performance criteria or company performance criteria were not achieved, then executive officers would not be entitled to any cash or equity bonuses. In 2006, the executive officers were eligible to receive an aggregate of approximately $390,000 and common stock options to purchase an aggregate of approximately 425,000 shares of Company common stock. Although the annual bonus structure is approved by the Compensation Committee, we are not obligated to issue specific bonuses and final bonus amounts are determined at the discretion of the Board of Directors. As of the date of this Proxy Statement, the Compensation Committee has not established the 2007 cash and equity bonus structure.
 
Stock Options
 
Our 2006 Stock Plan authorizes us to grant options to purchase shares of common stock to our employees, directors and consultants. Our Compensation Committee is the administrator of this stock plan. Stock option grants are made at the commencement of employment and may also be made following a significant change in job responsibilities or to meet other special retention or performance objectives. The Compensation Committee reviews and recommends initial stock option awards for executive officers based upon a review of competitive compensation data. In appropriate circumstances, the Compensation Committee considers the recommendations of our Chief Executive Officer when determining the amount of an initial option grant or the amount of an annual incentive option grant for executive officers. While we awarded stock options to our executive officers pursuant to our 2006 annual bonus structure, those awards were not made until the first quarter of 2007. Stock options granted by us have an exercise price equal to the fair market value of our common stock on the day of grant, typically vest 25% per annum based upon continued employment over a four-year period, and generally expire ten years after the date of grant. Incentive stock options also include certain other terms necessary to assure compliance with the Internal Revenue Code of 1986, as amended.
 
Potential Components of Compensation
 
In addition to granting incentive and nonstatutory stock options, our 2006 Stock Plan provides for the granting of restricted stock, restricted stock units, stock appreciation rights, performance units and shares, deferred compensation awards and other stock-based awards. The Compensation Committee may utilize some or all of these types of awards for executive officers if it believes that such awards are necessary to further the goals of the compensation program.
 
Compensation Committee Report
 
We, the Compensation Committee of the Board of Directors of Halozyme Therapeutics, Inc., have reviewed and discussed the Compensation Discussion and Analysis contained in this proxy statement with management. Based on such review and discussion, we have recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and in Halozyme’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

(1) Our Board of Directors approved a performance-based incentive plan on August 11, 2006 that provided for cash and equity awards based upon the accomplishment of specified individual and company performance criteria. The individual criteria for specific members of senior management varied from position to position, but all members of senior management had common company performance goals. The company performance criteria were based upon certain operational, clinical and financial performance goals identified by both management and the board of Directors. Members of senior management would still be eligible to receive a portion of their respective maximum bonus amounts even if all individual and company performance criteria were not met, provided, however, that a minimum combination of company and individual criteria had to be met in order to trigger a threshold amount of cash and equity awards. While the incentive plan was approved by our Compensation Committee, we were not obligated to issue bonuses and final bonus amounts were determined at the discretion of the Board of Directors. See “Compensation Discussion and Analysis — Plan-Based Awards.” The actual amount of cash paid to each named executive officer pursuant to the compensation guidelines established in 2006 is set forth in the Summary Compensation Table under the heading, “Non-Equity Incentive Plan Compensation.”
 
(2) Maximum equity awards for each executive officer under the incentive plan were derived from a formula that divided (i) the product of a target compensation percentage (75% for our Chief Executive Officer and 40% for all other executive officers) multiplied by the executive officer’s annual salary by (ii) our stock price on the actual date of grant for the underlying equity award (as adjusted for multiple year vesting). The maximum equity awards in the table above reflect the maximum share amounts as of February 5, 2007, the date that options were awarded pursuant to the incentive plan.
 
(3) An option to purchase 39,603 shares of common stock was granted to Dr. Lim on February 5, 2007 pursuant to the performance-based incentive plan established in 2006. One-third of the shares subject to the grant will vest on the one year anniversary of the grant, and 1/36 of the shares will vest monthly thereafter. The exercise price of these options is $7.51 per share.
 
(4) An option to purchase 12,943 shares of common stock was granted to Mr. Ramsay on February 5, 2007 pursuant to the performance-based incentive plan established in 2006. One-third of the shares subject to the grant will vest on the one year anniversary of the grant, and 1/36 of the shares will vest monthly thereafter. The exercise price of these options is $7.51 per share.
 
(5) An option to purchase 15,729 shares of common stock was granted to Dr. Frost on February 5, 2007 pursuant to the performance-based incentive plan established in 2006. One-third of the shares subject to the grant will vest on the one year anniversary of the grant, and 1/36 of the shares will vest monthly thereafter. The exercise price of these options is $7.51 per share.
 
(6) An option to purchase 17,976 shares of common stock was granted to Dr. Yocum on February 5, 2007 pursuant to the performance-based incentive plan established in 2006. One-third of the shares subject to the grant will

vest on the one year anniversary of the grant, and 1/36 of the shares will vest monthly thereafter. The exercise price of these options is $7.51 per share.
 
(7) An option to purchase 14,980 shares of common stock was granted to Mr. Kennard on February 5, 2007 pursuant to the performance-based incentive plan established in 2006. One-third of the shares subject to the grant will vest on the one year anniversary of the grant, and 1/36 of the shares will vest monthly thereafter. The exercise price of these options is $7.51 per share.

Potential Payments Upon Termination or Change in Control
 
While we have not entered into employment agreements with any of our employees or officers that provide for cash payments in connection with the conclusion of their employment, options granted to employees and officers of Halozyme under our 2001 Stock Plan and 2004 Stock Plan provide for full acceleration of the unvested portion of an option if the employee or officer is terminated without cause or resigns for certain specified reasons following certain change in control events. Assuming a change in control took place on December 31, 2006 and each of the named executive officers was terminated without cause immediately following the change in control, the foregoing individuals would have received the following amounts as a result of such accelerated vesting:

The assumptions used to calculate the value of option awards are set forth in Note 2 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2006 filed with the SEC on March 9, 2007. There can be no assurance that the options will ever be exercised (in which case no value will actually be realized by the executive) or that the value on exercise will be equal to the FAS 123R value shown in this column.

No additional options will be granted under the 2001 Stock Plan.

Material Features of the 2001 Stock Plan
 
As of December 31, 2006, we had reserved 6,968,173 shares of our Common Stock for issuance under the 2001 Stock Plan. At December 31, 2006, there were 5,438,511 shares issuable upon exercise of outstanding options under the 2001 Stock Plan, at a weighted average exercise price of $0.40. The 2001 Stock Plan provides for the granting of incentive and nonstatutory stock options to employees and nonstatutory stock options to consultants with exercise prices equal to the fair market value of our Common Stock on the date of grant. Options granted under the 2001 Stock Plan generally have a 10-year term and vest at the rate of 1/4 of the shares on the first anniversary of the date of grant and 1/48 of the shares monthly thereafter. Options granted to employees and officers of Halozyme under our 2001 Stock Plan provide for full acceleration of the unvested portion of an option if the option is not assumed or substituted by an acquiring entity in certain change in control events. Furthermore, if the option is substituted or assumed the unvested portion of the option will become fully vested if the option holder is terminated “without cause,” as defined in the 2001 Stock Plan, or resigns after an “adverse change,” as defined in the 2001 Stock Plan, following certain change in control events.
 
Material Features of the 2004 Stock Plan
 
As of December 31, 2006, we had reserved 3,031,827 shares of our Common Stock for issuance under the 2004 Stock Plan. At December 31, 2006, there were 2,645,561 shares issuable upon exercise of outstanding options under the 2004 Stock Plan, at a weighted average exercise price of $2.37. The 2004 Stock Plan provides for the granting of incentive and nonstatutory stock options to employees and nonstatutory stock options to consultants with exercise prices equal to the fair market value of our Common Stock on the date of grant. Options granted under the 2004 Stock Plan generally have a 10-year term and vest at the rate of 1/4 of the shares on the first anniversary of the date of grant and 1/48 of the shares monthly thereafter. Options granted to employees and officers of Halozyme under our 2004 Stock Plan provide for full acceleration of the unvested portion of an option if the option is not assumed or substituted by an acquiring entity upon a “Change in Control,” as defined under the 2004 Stock Plan.
 
Furthermore, if the option is substituted or assumed the unvested portion of the option will become fully vested if the option holder is terminated “without cause,” as defined in the 2004 Stock Plan, or resigns for “good reason,” as defined in the 2004 Stock Plan, following certain change in control events.
 
Material Features of the 2005 Outside Directors’ Stock Plan

At December 31, 2006, there were 60,000 shares issuable upon exercise of outstanding options under the 2005 Outside Directors’ Stock Plan at a weighted average exercise price of $2.55. The 2005 Outside Directors’ Stock Plan provides for the granting of nonstatutory stock options and restricted stock grants to non-employee directors that meet currently applicable standards for independence. The exercise prices for stock options granted under the 2005 Outside Directors’ Stock Plan equal the fair market value of our Common Stock on the date of grant. Options granted under the 2005 Outside Directors’ Stock Plan generally have a 10-year term and vest over one year. Options and restricted stock granted under our 2005 Outside Directors’ Stock Plan provide for full acceleration of the unvested portion of such options or restricted stock grants upon a “Change in Control,” as defined under the 2005 Outside Directors’ Stock Plan.

The 2006 Stock Plan provides for the granting of restricted stock, restricted stock units, incentive and nonstatutory stock options, stock appreciation rights, performance units and shares, deferred compensation awards and other stock-based awards. The Board will determine 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. 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.

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.
