PROXY STATEMENT

GENERAL INFORMATION ABOUT THE MEETING

Why are you receiving these proxy materials?

We are providing these proxy materials to you because Regeneron’s Board of Directors is asking (technically called soliciting) holders of the Company’s Common Stock and Class A Stock to provide proxies to be voted at our 2004 Annual Meeting of Shareholders. The Annual Meeting is scheduled for June 11, 2004, commencing at 10:30 a.m., at the Westchester Marriott Hotel, 670 White Plains Road, Tarrytown, New York 10591, and your proxy will be used at the Annual Meeting or at any adjournment or postponement of the meeting.

Who is entitled to vote at the Annual Meeting?

Only shareholders of record at the close of business on the record date, April 16, 2004, are entitled to vote shares of Common Stock and/or Class A Stock held on that date at the Annual Meeting. As of April 16, 2004, 53,272,266 shares of Common Stock and 2,365,873 shares of Class A Stock were issued and outstanding. The Common Stock and the Class A Stock vote together on all matters as a single class, with the Common Stock being entitled to one vote per share and the Class A Stock being entitled to ten votes per share.

What are you being asked to vote on?

We are asking you to vote on:

•

the election of directors;

•

the ratification of PricewaterhouseCoopers LLP as our independent auditors for 2004; and

•

a proposal to increase the number of shares reserved for issuance under our 2000 Long-Term Incentive Plan by 7,500,000 shares.

How can you vote?

You may vote by filling out, signing, and dating your proxy card and mailing it in the prepaid envelope included with these proxy materials. If you are a registered shareholder and attend the Annual Meeting, you may deliver your completed proxy card in person.

Can you change your vote or revoke your proxy?

Yes. You may change your vote or revoke your proxy at any time before the proxy is exercised. If you submitted your proxy by mail, you must (i) file with the Secretary of the Company or other designee of the Company, at or before the taking of the vote at the Annual Meeting, a written notice of revocation bearing a later date than the proxy or (ii) duly execute a later dated proxy relating to the same shares and deliver it to the Secretary of the Company or other designee before the taking of the vote at the Annual Meeting. Attendance at the Annual Meeting will not have the effect of revoking a proxy unless you give written notice of revocation to the Secretary before the proxy is exercised or you vote by written ballot at the Annual Meeting.

What constitutes a quorum?

The presence at the Annual Meeting, in person or by proxy, of the holders of the majority of the issued and outstanding shares of Common Stock and Class A Stock, taken together as a single class, on the record date will constitute a quorum. Both abstentions and broker non-votes are counted as present for purposes of determining the presence of a quorum. Broker non-votes occur when shares held by a shareholder in street name are not voted with respect to a proposal because the broker has not received voting instructions from the shareholder, and the broker lacks the discretionary voting power to vote the shares.

What vote is required to approve each item?

The election of directors will be determined by a plurality of the votes cast in person or by proxy at the Annual Meeting. All other matters presented to shareholders will be determined by the affirmative vote of a majority of the votes cast in person or by proxy at the Annual Meeting. Broker non-votes and abstentions will have no effect on the outcome of the vote for the election of directors. For the other matters presented to shareholders, broker non-votes and abstentions will have the same effect as a vote against the proposals.

What are the Board’s recommendations?

Unless you give other instructions when you vote, the persons named as proxy holders will vote:

•

FOR election of the three nominated directors;

•

FOR ratification of the designation of PricewaterhouseCoopers LLP to audit the books and accounts of the Company for 2004; and

•

FOR amending the 2000 Long-Term Incentive Plan to increase the number of shares reserved for issuance under the plan by 7,500,000 shares.

If any other matters should properly come before the Annual Meeting, the persons named in the enclosed proxy will have discretionary authority to vote such proxy on such matters in accordance with their best judgment.

PROPOSAL NO. 1: ELECTION OF DIRECTORS

According to the Company’s Certificate of Incorporation, the Board is divided into three classes, denominated Class I, Class II, and Class III, with members of each class holding office for staggered three-year terms. There are currently three Class I Directors whose terms expire at the 2004 Annual Meeting, three Class II Directors whose terms expire at the 2005 Annual Meeting, and four Class III Directors whose terms expire at the 2006 Annual Meeting (in all cases, subject to the election and qualification of their successors and to their earlier death, resignation or removal).

Biographical information is given below, as of April 16, 2004, for each nominee for Class I Director, and for each Class II and Class III Director whose term of office will continue after the Annual Meeting.

The Corporate Governance Committee will consider a nominee for election to the Board recommended by a shareholder of record, if the shareholder submits the nomination in compliance with the requirements of our by-laws. The Corporate Governance Committee does not yet have a formal policy for evaluating shareholder nominations, but intends to consider this matter during the upcoming year with a view to adopting such a policy prior to the 2005 Annual Meeting of Shareholders. The Corporate Governance Committee shall consider all relevant factors when identifying or evaluating potential Board nominees, whether nominated by members of the Board or shareholders, including, without limitation, the current composition of the Board and the potential nominee’s complementary skills, experience, areas of expertise, and reputation.

The Board has adopted a code of business conduct and ethics that applies to all of our employees, officers, and directors. You can find links to this code and our Board committee charters on our website under the “Corporate Governance” heading on the “Investor Relations” page at www.regeneron.com.

The Board has determined that each of the current members of the Audit Committee, Messrs. Baker, Ryan, and Sing, is an “audit committee financial expert” as that term is defined in Item 401(h) of Regulation S-K, and “independent” for purposes of item 7(d)(3)(iv) of Schedule 14A under the Securities Exchange Act of 1934, as amended.

Board Meetings and Attendance of Directors

The Board held nine meetings in 2003. All directors attended more than 75% of the total number of meetings of the Board and committees of the Board held while they were members. Commencing in 2004, at the recommendation of the Corporate Governance Committee, the Board has adopted the practice of conducting executive sessions of independent directors following each regularly scheduled Board meeting. Board members are expected to attend the Company’s Annual Meeting of Shareholders absent a pressing reason, although the Company has no formal policy on the matter. All but one of the directors attended our 2003 Annual Meeting of Shareholders.

Compensation of Directors

Employee directors receive no compensation for services rendered in their capacity as directors. Non-employee directors receive an annual retainer of $15,000 and a fee of $5,000 for each Board meeting attended in person or, once a year, by telephone or videoconference. No additional retainer is paid for committee service. Non-employee directors are reimbursed for their actual expenses relating to their attendance at Board meetings.

Under the Company’s 2000 Long-Term Incentive Plan, each non-employee director receives an automatic grant of an option to purchase 15,000 shares of Common Stock on the first business day after January 1 of each year, with an exercise price per share equal to the fair market value of a share of Common Stock on the date of grant. These options are exercisable as to one-third of the shares on the anniversary of the date of grant in each of the three subsequent calendar years, and expire ten years following the date of grant. Options granted to directors in 2001, 2002, and 2003 included a “reload” provision. Non-employee directors who use shares of Common Stock held for at least six months to pay the exercise price of options granted with reload provisions can receive a new option for the number of shares equal to the number of shares surrendered. The new option will be granted at an exercise price equal to the fair market value of a share of Common Stock on the date of grant of the new option and will have an expiration date that is the same as that of the initial option grant. Options granted to non-employee directors in 2002 and 2003 included a “change of control” provision, which would cause the immediate vesting of the options in the event that the director’s service as a member of the Board is terminated without cause within two years of a defined “change of control.” Each non-employee director would have the right to nullify this acceleration of vesting, in whole or in part, if it would cause the director to pay excise taxes under Internal Revenue Code Section 4999.

Upon his joining the Board in January 2003, the Company granted Mr. Ryan an option, pursuant to the 2000 Long-Term Incentive Plan, to purchase up to 25,000 shares of Common Stock at an exercise price of $20.97, the fair market value of a share of Common Stock on the date of grant. This option vests in equal installments over three years and expires ten years following the date of grant. The option contains “reload” and “change of control” provisions as described above.

In accordance with an agreement dated as of January 8, 1995 between Dr. Vagelos and the Company, Dr. Vagelos purchased 600,000 shares of Common Stock for $300,000. He also received an option to purchase up to 285,000 shares of Common Stock at the fair market value of the Common Stock as of the date of grant, or $3.50 per share. On December 31, 1998, Dr. Vagelos entered into an employment

agreement with Regeneron, pursuant to which, effective January 1, 1999, he became a part-time employee. Dr. Vagelos did not become an officer of Regeneron or change his title. His annual compensation as an employee is $100,000. In accordance with the employment agreement, in 1999, the Company issued Dr. Vagelos an option, pursuant to the 1990 Long-Term Incentive Plan, to purchase up to 162,500 shares of Common Stock at an exercise price of $7.41 per share; the option vested over five years. In addition, the Company agreed to recommend to the Compensation Committee that Dr. Vagelos be granted additional stock option grants on or about January 1, 2000 through 2003 in the amount of the greater of (a) 125,000 shares or (b) 125% of the highest annual option grant made to an officer of the Company at the time of each respective year’s annual grant to officers. The Company agreed to recommend a vesting schedule for each year’s annual grant to Dr. Vagelos that would decline ratably from five years for the grant in 1999, to one year for the grant in 2003. On December 15, 2003, the Company issued Dr. Vagelos an option, pursuant to the 2000 Long-Term Incentive Plan, to purchase 312,500 shares of Common Stock at an exercise price of $13.00 per share; the option vests over one year and contains “reload” and “change of control” provisions identical to the ones described for independent directors. If Dr. Vagelos dies or is disabled while he is employed by the Company, all options granted by the Company to him will immediately become exercisable at the time of death or disability.

PROPOSAL NO. 2: APPROVAL OF AUDITORS

The Board of Directors, at the recommendation of the Audit Committee, has selected PricewaterhouseCoopers LLP as the Company’s independent auditors for the fiscal year ending December 31, 2004. This appointment is subject to the approval of the Company’s shareholders. Accordingly, the following resolution will be offered at the Annual Meeting:

“RESOLVED, that the appointment by the Board of Directors of Regeneron Pharmaceuticals, Inc., of PricewaterhouseCoopers LLP as the independent auditors of the Company for the year ending December 31, 2004 is hereby approved.”

PricewaterhouseCoopers LLP has been the Company’s independent auditors for the past fifteen years and has advised the Company that it will have in attendance at the Annual Meeting a representative who will be afforded an opportunity to make a statement, if such representative desires to do so, and will respond to appropriate questions presented at the Annual Meeting.

Information about Fees Paid to Independent Auditors

Aggregate fees incurred related to services provided to the Company by PricewaterhouseCoopers LLP for the years ended December 31, 2003 and 2002 were:

	2003	2002
Audit Fees	$177,300	$134,000
Audit Related Fees	172,280	44,700
Tax Fees	—	5,635
All Other Fees	3,200	20,183
Total Fees	$352,780	$204,518

Audit fees in 2002 and 2003 were for professional services rendered for the audit of the Company’s financial statements for the fiscal year and reviews of the Company’s quarterly financial statements included in its Form 10-Q filings.

Audit related fees for 2002 were primarily for the audit of the Company’s 401(k) Savings Plan and accounting advice and consultation concerning financial accounting matters. Audit related fees for 2003 were primarily for accounting advice and consultation concerning financial accounting and reporting matters. Fees for the 2003 audit of the Company’s 401(k) Savings Plan are not included in the amounts reported above since this work has not yet been initiated.

Tax fees in 2002 were for tax planning and advisory services.

All Other fees for 2002 were for advisory services related to risk management and investment incentives. All Other fees for 2003 were for advisory services related to investment incentives and miscellaneous other matters. PricewaterhouseCoopers LLP did not perform any professional services in connection with financial information systems design and implementation in 2002 or 2003.

The Audit Committee has adopted a policy regarding the pre-approval of audit and permitted non-audit services to be performed by the Company’s independent auditor, PricewaterhouseCoopers LLP. The Audit Committee will, on an annual basis, consider and, if appropriate, approve the provision of audit and non-audit services by PricewaterhouseCoopers. In 2003, the Audit Committee pre-approved a general provision of $50,000 for certain types of accounting advisory services; however, no one engagement under the general provision could have an expected cost greater than $25,000. Management is responsible for notifying the Audit Committee of the status of accounting advisory service engagements at regularly scheduled Audit Committee meetings and the general provision is replenished to $50,000, as necessary. For any accounting advisory engagement expected to cost greater than $25,000, and for any other permissible consulting

engagement, management is required to request specific pre-approval from the Audit Committee or the Chairman of the Audit Committee.

The Board of Directors Unanimously Recommends a Vote FOR the Selection of PricewaterhouseCoopers LLP as the Company’s Independent Auditors.

AUDIT COMMITTEE REPORT

We have reviewed the audited financial statements of the Company for the year ended December 31, 2003, which are included in the Company’s Annual Report on Form 10-K and met with both management and PricewaterhouseCoopers LLP, the Company’s independent auditors, to discuss those financial statements. The Audit Committee has discussed with the Company’s independent auditors the matters required to be discussed under Statements on Auditing Standards No. 61, which include, among other items, matters related to the conduct of the audit of the Company’s financial statements. The Audit Committee also discussed with the independent auditors their independence relative to the Company and received and reviewed the written disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1 (which relates to the auditor’s independence from the Company).

Based on the foregoing discussions and review, the Audit Committee recommended to the Board that the audited financial statements of the Company for the year ended December 31, 2003 be included in the Company’s Annual Report on Form 10-K for filing with the Securities and Exchange Commission.

PROPOSAL NO. 3: AMENDMENT TO 2000 LONG-TERM INCENTIVE PLAN

On June 9, 2000, the Company’s shareholders adopted and approved the Company’s 2000 Long-Term Incentive Plan (the 2000 Plan) and 6,000,000 shares of Common Stock were reserved for issuance thereunder. An additional 5,000,000 shares were reserved under the 2000 Plan in June 2002. As of April 16, 2004 1,612,020 shares remained available for issuance under the 2000 Plan.

On April 2, 2004, the Board, at the recommendation of the Compensation Committee and subject to shareholder approval, adopted an amendment to the 2000 Plan to increase the maximum number of shares reserved for and available for issuance under the 2000 Plan to 18,500,000, of which 7,500,000 represent an increase over the number of shares previously reserved under the 2000 Plan. The purpose of this amendment is to replenish the number of shares available for grant as incentive awards in order for the Company to continue to meet our objective of securing, motivating, and retaining qualified officers and employees, and of compensating non-employee directors.

Based on management’s employment and award projections, the Compensation Committee determined that the proposed increase in shares reserved for issuance under the 2000 Plan should satisfy the Company’s compensation needs for at least the next three years, including the regular annual grants anticipated at the end of 2004. The Compensation Committee determined that it would engage the services of an outside compensation consultant in 2004 to evaluate the Company’s current compensation practices in order to ensure that future quantities and types of awards under the 2000 Plan continue to reflect the Company’s needs and current compensation practices for similarly situated companies.

Future grants under the 2000 Plan will be made at the discretion of the Compensation Committee and, accordingly, are not yet determinable. In addition, benefits under the 2000 Plan will depend on a

number of factors, including the fair market value of Common Stock on future dates and the exercise decisions made by the participants. Consequently, it is not possible to determine the benefits that might be received by participants receiving discretionary grants under the 2000 Plan.

The Board of Directors Unanimously Recommends a Vote FOR the Approval of the Amendment to the 2000 Plan to Increase the Number of Shares Reserved and Available for Issuance Thereunder by 7,500,000 Shares.

Description of Principal Features of the 2000 Plan

The 2000 Plan is administered by the Compensation Committee of the Board. Each member of the Compensation Committee is a “non-employee director” (within the meaning of Rule 16b-3 promulgated under Section 16 of the Securities Exchange Act of 1934, as amended) and an “outside director” (within the meaning of Section 162(m) of the Internal Revenue Code).

The 2000 Plan may be amended by the Board, subject to shareholder approval where necessary, to satisfy certain regulatory requirements. The 2000 Plan will terminate not later than the close of business on April 24, 2010. However, awards granted before the termination of the 2000 Plan may extend beyond that date in accordance with their terms.

There are generally four types of awards that may be granted under the 2000 Plan: Stock Options (including both incentive stock options (referred to as ISOs) within the meaning of Section 422 of the Internal Revenue Code and nonqualified stock options (referred to as NQSOs), which are options that do not qualify as ISOs), Restricted Stock, Phantom Stock, and Stock Bonus awards. In addition, the Compensation Committee in its discretion may make other awards valued in whole or in part by reference to, or otherwise based on, Common Stock.

Prior to the effectiveness of the proposed amendment, there were reserved for issuance under the 2000 Plan a total of 11,000,000 shares of Common Stock. As of April 16, 2004 1,612,020 shares remained available for issuance under the 2000 Plan. If the proposed amendment is approved, an additional 7,500,000 shares of Common Stock will be reserved for issuance under the 2000 Plan. All of the shares reserved for issuance under the 2000 Plan are generally subject to equitable adjustment upon the occurrence of any stock dividend or other distribution, recapitalization, stock split, subdivision, reorganization, merger, consolidation, combination, repurchase or share exchange, or other similar corporate transaction or event. The maximum number of shares of Common Stock that may be the subject of awards to a participant in any year is 1,000,000, except that such number is 1,500,000 with respect to an employee’s initial year of employment with the Company.

Awards become exercisable or otherwise vest at the times and upon the conditions that the Committee may determine, as reflected in the applicable award agreement. The Compensation Committee has the authority to accelerate the vesting and/or exercisability of any outstanding award at such times and under such circumstances as it, in its sole discretion, deems appropriate (for instance, upon a “Change in Control” of the Company, as defined in the 2000 Plan). Because awards under the 2000 Plan are discretionary (other than annual grants to non-employee directors described under “Non-employee Director Awards” below), it is not possible to determine the size of future awards.

Stock Options. Options entitle the holder to purchase shares of Common Stock during a specified period at a purchase price specified by the Compensation Committee (but in the case of an ISO, at a price not less than 100% of the fair market value of the Common Stock on the day the ISO is granted). Each Option granted under the 2000 Plan will be exercisable for a period of 10 years from the date of grant, or such lesser period as the Compensation Committee shall determine. Options may be exercised, in whole or in part, by the payment of cash of the full option price of the shares purchased, by tendering shares of Common Stock with a fair market value equal to the option price of the shares purchased, or by other methods in the discretion of the Compensation Committee. The 2000 Plan provides that, unless otherwise determined by the Compensation Committee, an Option shall vest with respect to 20% of the Option on the first anniversary of the date of grant and with respect to an additional 20% on each of the next four

anniversaries thereof. In 2001, the Compensation Committee determined that beginning in 2001, Options granted under the 2000 Plan would vest ratably over four years, with 25% of the Option vesting on each of the first four anniversaries of the date of grant. Options that are exercisable as of the date of a participant’s termination of service with the Company may be exercised after such date for the period set forth in the Option agreement or as otherwise determined by the Compensation Committee. In the event of the death of a participant, any unexercisable Options held by such participant shall become duly exercisable by the participant’s heirs or personal representatives. Options held by a participant upon termination from the Company’s service for “Cause” (as defined in the 2000 Plan) shall immediately expire (whether or not then exercisable). The Compensation Committee may provide that a participant who delivers shares of Common Stock to exercise an Option will automatically be granted new Options for the number of shares delivered to exercise the Option (referred to as Reload Options). Reload Options will be subject to the same terms and conditions as the related Option (except that the exercise price generally will be the fair market value of the Common Stock on the date the Reload Option is granted).

Restricted Stock. Restricted Stock Awards consist of a grant of shares of restricted Common Stock. The Compensation Committee may determine the price, if any, to be paid by a participant for each share of Restricted Stock subject to an award. A holder of Restricted Stock may vote and, if the participant remains in the service of the Company throughout the “Restricted Period” as defined in the 2000 Plan, he or she may generally receive all dividends on all such shares. However, such holder may not transfer such shares during the Restricted Period. If for any reason during the Restricted Period a holder of Restricted Stock ceases to be in the service of the Company, the holder may (and if the termination is on account of Cause, shall) be required to transfer to the Company such Restricted Stock together with any dividends paid thereon. Consistent with Section 162(m) of the Internal Revenue Code, the 2000 Plan provides that (i) restrictions on Restricted Stock may, in the sole discretion of the Compensation Committee, lapse upon the achievement of certain pre-established performance goals based upon the criteria described below, and (ii) the maximum number of such performance-based Restricted Stock awards that may be granted to an employee in any year is 200,000.

The 2000 Plan provides that performance goals will be based on one or more of the following criteria: (1) return on total shareholder equity; (2) earnings per share of Common Stock; (3) net income (before or after taxes); (4) earnings before interest, taxes, depreciation and amortization; (5) revenues; (6) return on assets; (7) market share; (8) cost reduction goals; (9) any combination of, or a specified increase in, any of the foregoing; (10) the achievement of certain target levels of discovery and/or development of products, including without limitation, the regulatory approval of new products; (11) the achievement of certain target levels of sales of new products or licensing in or out of new drugs; (12) the formation of joint ventures, research or development collaborations, or the completion of other corporate transactions; and (13) such other criteria as the shareholders of the Company may approve. In addition, such performance goals may be based upon the attainment of specified levels of Company performance under one or more of the measures described above relative to the performance of other corporations. To the extent permitted under Section 162(m) of the Internal Revenue Code (including, without limitation, compliance with any requirements for shareholder approval), the Compensation Committee may designate additional business criteria on which the performance goals may be based or adjust, modify, or amend the aforementioned business criteria.

Phantom Stock. A Phantom Stock award is an award of the right to receive cash or Common Stock at a future date, subject to such restrictions, if any, as the Compensation Committee may impose at the date of grant or thereafter, which restrictions may lapse separately or in combination at such times, under such circumstances (including without limitation a specified period of employment or the satisfaction of the performance goals described above), in such installments, or otherwise, as the Compensation Committee may determine. The grant of a Phantom Stock award shall not reduce the number of shares of Common Stock with respect to which awards may be granted under the 2000 Plan.

Stock Bonus. If the Compensation Committee grants a Stock Bonus award, a certificate for the shares of Common Stock constituting such Stock Bonus is issued in the name of the participant to whom such grant was made.

Non-employee Director Awards. On the first business day after January 1 of each calendar year, each then serving non-employee director of the Company will be granted a NQSO to purchase 15,000 shares of Common Stock at the fair market value of such shares at the time of grant; such NQSOs shall become exercisable as to 33 1/3% of the shares covered thereby on each of the first, second, and third anniversaries of the date of grant, and shall expire (if not earlier terminated) on the tenth anniversary of the date of grant. In addition, a non-employee director may receive such other awards as are approved by a majority of the Board.

Certain Federal Income Tax Consequences

Set forth below is a discussion of certain federal income tax consequences with respect to Options that may be granted pursuant to the 2000 Plan. The following discussion is a brief summary only, and reference is made to the Internal Revenue Code and the regulations and interpretations issued thereunder for a complete statement of all relevant federal tax consequences. This summary is not intended to be exhaustive and does not describe state, local, or foreign tax consequences of participation in the 2000 Plan.

Incentive Stock Options. In general, no taxable income is realized by a participant upon the grant of an incentive stock option, within the meaning of Section 422 of the Internal Revenue Code. If shares of Common Stock are issued to a participant (“Option Shares”) pursuant to the exercise of an ISO granted under the 2000 Plan and the participant does not dispose of the Option Shares within the two-year period after the date of grant or within one year after the receipt of such Option Shares by the participant (a “disqualifying disposition”), then, generally (i) the participant will not realize ordinary income upon exercise and (ii) upon sale of such Option Shares, any amount realized in excess of the exercise price paid for the Option Shares will be taxed to such participant as capital gain (or loss). Long-term capital gain of a participant is generally subject to a maximum tax rate of up to 15% in respect of property held for more than one year. The amount by which the fair market value of the Common Stock on the exercise date of an ISO exceeds the purchase price generally will constitute an item which increases the participant’s “alternative minimum taxable income.”

If Option Shares acquired upon the exercise of an ISO are disposed of in a disqualifying disposition, the participant generally would include in ordinary income in the year of disposition an amount equal to the excess of the fair market value of the Option Shares at the time of exercise (or, if less, the amount realized on the disposition of the Option Shares), over the exercise price paid for the Option Shares.

Subject to certain exceptions, an ISO generally will not be treated as an ISO if it is exercised more than three months following termination of employment. If an ISO is exercised at a time when it no longer qualifies as an ISO, such option will be treated as an NQSO as discussed below.

Nonqualified Stock Options. In general, no taxable income is realized by a participant upon the grant of an NQSO. Upon exercise of an NQSO, the participant generally would include in ordinary income at the time of exercise an amount equal to the excess, if any, of the fair market value of the Option Shares at the time of exercise over the exercise price paid for the Option Shares.

In the event of a subsequent sale of Option Shares received upon the exercise of an NQSO, any appreciation or depreciation after the date on which taxable income is realized by the participant in respect of the option exercise will be taxed as capital gain in an amount equal to the excess of the sale proceeds for the Option Shares over the participant’s basis in such Option Shares. The participant’s basis in the Option Shares will generally equal the amount paid for the Option Shares plus the amount included in ordinary income by the participant upon exercise of the NQSO described in the immediately preceding paragraph.

Interests of Certain Persons in Matters to Be Acted Upon

Officers of the Company, including the Named Officers, employees, consultants and non-employee directors of the Company are eligible to receive awards under the 2000 Plan in the discretion of the Compensation Committee.

Options granted to Named Officers in 2003 included a “reload” provision. Named Officers who use shares of Common Stock held for at least six months to pay the exercise price of options granted with reload provisions can receive a new option for a number of shares equal to the number of shares surrendered. The new option will be granted at an exercise price equal to the fair market value of a share of Common Stock on the date of grant and will have an expiration date that is the same as that of the initial option grant.

Employment Agreements

The Company entered into an employment agreement with Leonard S. Schleifer, M.D., Ph.D., effective as of December 20, 2002, providing for his employment with the Company through December 31, 2003 and continuing thereafter on a year-by-year basis unless notice is given by Dr. Schleifer or the Company. Pursuant to the agreement, during the term of his employment, the Company will pay Dr. Schleifer a base salary of not less than $575,000, with such increases as may be determined by the Compensation Committee and approved by the Board. Under his employment agreement, Dr. Schleifer may

participate in all Company benefit and incentive programs. During his employment term, the Company will maintain life insurance on Dr. Schleifer’s life in the amount of $1,000,000 payable to beneficiaries designated by Dr. Schleifer. The Company also agreed to maintain long term disability insurance that will pay Dr. Schleifer at least 65% of his salary if he is physically or mentally unable to work. Under the employment agreement, the Company has agreed that in the event that Dr. Schleifer’s employment is terminated other than for cause (as defined in the agreement) or is terminated by Dr. Schleifer for good reason (as defined in the agreement to include specified acts of constructive termination, as well as the first year following a change in control of the Company) (collectively, as “Involuntary Termination”), the Company will pay Dr. Schleifer an amount equal to 125% of the sum of his base salary plus his average bonus paid over the past three years, and continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance for 18 months. The Company has agreed that in the event that Dr. Schleifer’s employment is terminated for any reason other than for cause (as defined in the agreement), all of his unexercisable stock options will continue to vest in accordance with the terms of the applicable grant agreement and Dr. Schleifer shall be entitled to exercise the stock options during the original term of such options. Upon an Involuntary Termination within three years after a change in control of the Company or within three months prior thereto, the Company will pay Dr. Schleifer an amount equal to three times the sum of his base salary in effect plus his average bonus paid over the past three years, and continue to provide Dr. Schleifer and his dependents medical, dental, and life insurance for 36 months. If payments under the agreement resulting from a change in ownership as defined in Section 280G(b)(2) of the Internal Revenue Code exceed certain thresholds, then the Company will pay to Dr. Schleifer an additional amount to cover any exercise tax obligations arising therefrom, unless such excise tax obligations could be eliminated altogether by reducing Dr. Schleifer’s cash payments and benefits under the agreement by less than ten percent in which case such benefits and payments will be reduced accordingly.

On March 6, 2000, the Company entered into an employment agreement with George D. Yancopoulos, M.D., Ph.D. providing for his employment with the Company through March 5, 2005. During the term of employment, the Company will pay Dr. Yancopoulos an annual base salary of $370,000, with such increases as may be determined by the Compensation Committee and approved by the Board. Dr. Yancopoulos is also entitled to participate in all Company benefit plans and incentive plans provided to similarly situated executives of the Company. The employment agreement provides that in the event that Dr. Yancopoulos’ employment is terminated (i) by the Company without cause, as defined in the employment agreement, (ii) by reason of the executive’s death, or (iii) by reason of the executive’s disability, as determined in good faith by the Board, Dr. Yancopoulos, or his estate, as the case may be, will continue to be paid his base salary and benefits payable under the agreement for the lesser of one year or the remainder of the term of the agreement. Under the employment agreement, Dr. Yancopoulos has agreed that he will not engage in activities which are in competition with the Company for a period of one year following the termination of his active employment with the Company.

For a description of the Company’s employment agreement with P. Roy Vagelos, M.D., see “Compensation of Directors.”

Indebtedness of Named Officers

In August 1994, the Company loaned Dr. Yancopoulos $60,000. The loan is evidenced by a promissory note bearing interest at the rate of 6.83% per year. The loan, including all accrued interest, totaled $99,461 as of April 16, 2004, and becomes due and payable on August 21, 2004, unless Dr. Yancopoulos’s employment with the Company terminates prior to that date.

COMPENSATION COMMITTEE REPORT

The Company’s executive compensation program is administered by the Compensation Committee, which is composed of two independent directors, Messrs. Baker and Sing. Mr. Baker serves as chairman of the Compensation Committee. Subject to approval by the Board, it is part of the Compensation Committee’s responsibility to oversee the Company’s compensation plans and practices and review and

establish the individual compensation levels for executive officers, including Dr. Schleifer, the Company’s Chief Executive Officer. The Compensation Committee considers the views and recommendations of independent consultants, management, and other directors in determining whether the amounts and types of compensation the company pays its executive officers are appropriate. The Compensation Committee also takes into account the Company’s overall performance and independent survey data regarding similarly situated executives at other companies in the biotechnology industry.

Compensation Philosophy

The Company’s executive compensation program is designed to promote the achievement of the Company’s business objectives and, thereby, to maximize long-term corporate performance and shareholder value. The program is intended to provide compensation opportunities that are based, in substantial part, on the Company’s performance, as well as the individual contributions of each executive officer consistent with the Company’s performance. The compensation packages for executive officers consist of a combination of base salary, bonuses, and long-term stock-based incentives through the 2000 Plan.

The Compensation Committee believes it is important for stock-based incentives to constitute a significant portion of the compensation package in order to help align executive and shareholder interests. Stock options granted to the Company’s executive officers and other employees of the Company (with the exception of Dr. Vagelos) include vesting provisions of 25% per year over four years. The Compensation Committee believes that by rationing the exercisability of these stock options over future years, the executive retention impact of these awards will be strengthened.

In determining the total amount and mixture of the compensation package for each executive officer, including Dr. Schleifer, the Compensation Committee considers numerous factors, the most important of which are (i) the Company’s overall performance, needs, and objectives, including attracting, motivating, and retaining key management personnel, (ii) individual performance, including the executive officer’s contribution to the Company’s objectives, (iii) compensation of persons holding comparable positions at other similarly situated biotechnology companies, and (iv) the overall value to each executive officer of his or her compensation package. No specific numerical weight is given to any of these factors. The 2003 base salaries, bonuses, and other compensation of the Named Officers, which were established in late 2002, are shown in the Summary Compensation Table.

Chief Executive Officer Compensation

Dr. Schleifer received an annual incentive bonus for fiscal year 2003 equal to $355,000, which was unchanged from the bonus he was awarded for fiscal year 2002. In addition, Dr. Schleifer was granted an option to purchase 250,000 shares at $13 per share (the then current fair market value of the Common Stock), which was also unchanged from his award at the end of 2002. The options granted to Dr. Schleifer vest over four years (25% per year) commencing on the anniversary of the date of the grant. Among the factors considered by the Compensation Committee in evaluating Dr. Schleifer’s performance for fiscal year 2003 was the progress in initiating, conducting, and advancing the Company’s pre-clinical and clinical programs versus the Company’s 2003 Key Goals established, with Board approval, at the end of fiscal 2002 and the Company’s efforts in establishing important corporate collaborations in 2003.

Section 162(m) of the Internal Revenue Code

Section 162(m) of the Internal Revenue Code limits the deductibility of compensation over $1 million to the Chief Executive Officer and the other Named Officers unless certain conditions are met. The Company’s Chief Executive Officer and the other Named Officers have not received compensation over $1 million.

This Item requires disclosure of certain transactions between the Company or a subsidiary of the Company and (i) a director, (ii) officer, (iii) holder of five percent of any class of Company voting securities (or any member of the immediate family member of the foregoing persons), (iv) any corporation or organization (other than the registrant or a majority-owned subsidiary of the registrant) of which any of the persons specified in (i) or (ii) is an executive officer or partner or is, directly or indirectly, the beneficial owner of ten percent or more of any class of securities, or (v) any trust or other estate in which any of the persons specified in (i) or (ii) has a substantial beneficial interest or as to which such person serves as a trustee or in a similar capacity.

OTHER MATTERS

When are shareholder proposals due for the 2005 Annual Meeting of Shareholders?

A shareholder wishing to present a proposal at the 2005 Annual Meeting of Shareholders must submit the proposal in writing and be received by the Company at its principal executive offices at 777 Old Saw Mill River Road, Tarrytown, New York 10591 by January 6, 2005 in order for such proposal to be considered for inclusion in the Company’s proxy statement and form of proxy relating to that meeting.

What happens if multiple shareholders share an address?

Applicable rules permit brokerage firms and the Company to send one Annual Report and proxy statement to multiple shareholders who share the same address under certain circumstances. This practice is known as “householding.” We believe that householding will provide greater convenience for our shareholders, as well as cost savings for us by reducing the number of duplicate documents that are sent to your home. Consequently, we have implemented the practice of householding for shares held in “street name” and intend to deliver only one Annual Report and one proxy statement to multiple shareholders sharing the same address. If you wish to receive a separate proxy statement for the 2004 Annual Meeting or a 2003 Annual Report, you may find these materials at our internet website (www.regeneron.com) or you may stop householding for your account and receive separate printed copies of these materials by contacting our Investor Relations Department, at Regeneron Pharmaceuticals, Inc., 777 Old Saw Mill River Road, Tarrytown, New York 10591, or by calling us at 914-345-7741. If you hold shares registered in your name (sometimes called a shareholder of record), you can elect householding for your account by contacting us in the same manner described above or marking the “YES” box on the enclosed proxy card under the “Householding Election” heading. Please note that for shareholders of record, if you do not mark the “NO” box on the enclosed proxy card under the “Householding Election” heading, you will be deemed to have consented, and householding will start for your account within 60 days after the mailing of this proxy statement. Any shareholder may stop householding for your account by contacting our Investor Relations Department at the address and/or phone number included above. If you revoke your consent, you will be removed from the householding program within 30 days of receipt of your revocation and each shareholder at your address will receive individual copies of our disclosure documents.

Are there any other matters to be addressed at the Annual Meeting?

We know of no other matters to be brought before the Annual Meeting, but if other matters are brought up before or at the meeting, the persons named in your proxy will have discretionary authority to vote such proxy on such matters in accordance with their best judgment.

Who will pay the costs related to this proxy statement and the Annual Meeting?

We will be responsible for paying for al expenses to prepare, print and mail the proxy materials to shareholders. In accordance with the regulations of the Securities and Exchange Commission, we will make arrangements with brokerage houses and other custodians, nominees, and fiduciaries to send proxies and proxy materials to their principals and will reimburse them for their reasonable expenses in so doing. In addition to the solicitation by use of the mails, our officers, directors, and employees may solicit the return of proxies by telephone, telegram, or personal interviews.

When can you expect to receive a 2003 Annual Report?

Our Annual Report for the year ended December 31, 2003 is being mailed or made available electronically to shareholders together with these proxy materials. Both the Annual Report and this proxy statement will be posted at our corporate website (www.regeneron.com) soon after they are distributed to shareholders. In addition, interested shareholders may obtain without charge a copy of our Annual Report on Form 10-K and/or other recent filings with the Securities and Exchange Commission by contacting our Investor Relations Department at (914) 345-7741.
