For his service as Chairman of the Board, Dr. Vagelos receives an additional $70,000. In accordance with an agreement dated as of January 8, 1995 between Dr. Vagelos and the Company, Dr. Vagelos purchased 600,000 restricted shares of Common Stock ("Restricted Shares"), for $300,000. He also received an option to purchase up to 285,000 shares of the Company's Common Stock. The Restricted Shares are nontransferable with such restriction lapsing ratably over a five year period. The stock options entitle Dr. Vagelos to purchase an equal number of shares of Common Stock at the fair market value of the Common Stock as of the date of grant, or $3.50 per share. In June 1991, the shareholders of the Company approved an amendment to the Company's Long-Term Incentive Plan to provide for an annual grant to each member of the Board of Directors who is not at the time of grant an employee of the Company or any subsidiary of the Company (an "Outside Director") an option to purchase 5,000 shares of Common Stock with an exercise price per share equal to the fair market value of a share of Common Stock on the date of grant. The grant occurs on March 1 of each year prior to the termination of the Long-Term Incentive Plan, except that the grant made in 1991 occurred on June 24, 1991, the first business day after the 1991 Annual Meeting. An option so granted is exercisable as to one-third of the shares on each of the three subsequent calendar years, and will expire ten years following the date of grant. If prior to the option's expiration or exercise the grantee ceases to be a voting member of the Board of Directors, then the portion of the option that at that time is not exercisable will expire and the portion of the option, if any, that is exercisable may be exercised during the three months after which the director ceases to be a voting member of the Board of Directors. In June 1995, the shareholders approved an amendment to the Company's Long-Term Incentive Plan to increase by 5,000 shares, to a total of 10,000 shares, the number of shares of Common Stock subject to the above automatic grant to each Outside Director. Pursuant to this amendment, on March 13, 1995, each Outside Director was granted an additional option to purchase 5,000 shares of Common Stock with an exercise price per share equal to the fair market value on that date, or $6.00, subject otherwise to the same terms and conditions as the automatic annual stock option grant currently in effect under the Long-Term Incentive Plan. In 1995, the Company paid Dr. Shooter $60,000 for services provided as Chairman of the Scientific Advisory Board. In addition, the Company paid Drs. Brown, Gilman, Goldstein, and Vagelos $15,000 each as members of the Scientific Advisory Board. ------------------------------ -page 7- EXECUTIVE COMPENSATION Set forth below is information concerning the annual and long-term compensation for each of the last three fiscal years for the Company's Chief Executive Officer and its four other highest-compensated executive officers (the "Named Officers").

EMPLOYMENT AGREEMENT The Company has an agreement with Dr. Schleifer providing for his employment with the Company through December 31, 1997. During the term of his employment, the Company will pay Dr. Schleifer a base salary of $315,000, with such increases as may be determined by the Compensation Committee and approved by the Board of Directors. Under his employment agreement, Dr. Schleifer may participate in all Company benefit and incentive programs. During his employment term, the Company maintains life insurance on Dr. Schleifer's life in the amount of $1,000,000 payable to beneficiaries designated by Dr. Schleifer. Also under the employment agreement, the Company has agreed that in the event that Dr. Schleifer's employment is terminated other than for cause or is terminated by Dr. Schleifer for good reason (defined to include specified acts of constructive termination, as well as the first year following a change in control of the Company), the Company will pay Dr. Schleifer his base salary for 15 months, continue to provide Dr. Schleifer and his dependents medical and dental insurance and life insurance for 18 months, and accelerate certain otherwise unexercisable stock options granted to Dr. Schleifer. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Company's executive compensation program is administered by the Compensation Committee, which is comprised of three non-employee directors. Subject to approval by the Board of Directors, the Compensation Committee is responsible for (among other things) determining the compensation package of each executive officer. The Compensation Committee considers the views and recommendations of other directors, including those of Dr. Vagelos and Dr. Schleifer, in making decisions regarding the compensation of the Company's executive officers. ------------------------------ -page 9- 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 compensation of the executive officers consists of a combination of base salary, bonuses, and long- term stock-based incentives through the Company's Long-Term Incentive Plan. The Compensation Committee believes it is important to have stock incentives constitute a significant portion of the compensation package in order to help align executive and shareholder interests. In determining the total amount and mixture of the compensation package for each executive officer, including Dr. Schleifer and the other Named Officers, the Compensation Committee and the Board consider numerous factors, the most important of which are (i) the Company's long-term needs and objectives, including attracting, motivating, and retaining key management personnel, (ii) individual performance, including the expected contribution to the Company's objectives of each executive officer, (iii) compensation of persons holding comparable positions, including data obtained from outside studies and proxy materials on the payment of executive officers at comparable companies as well as the Company's most direct competitors, and (iv) the overall value to each executive of his or her compensation package. No specific numerical weight is given to any of these factors. The 1995 base salaries of the Named Officers other than Dr. Schleifer increased by an average of 5.68 percent over 1994. These increases were made in January 1995 and reflected the Committee's review in late 1994 of individual performance and internal and outside compensation studies of competitive and regional factors. Dr. Schleifer's 1995 compensation package was based on the same factors as described above for all executive officers pursuant to the Company's executive compensation objectives. In 1995, Dr. Schleifer's base salary increased 5.19 percent over 1994. In addition, the Compensation Committee directed that Dr. Schleifer be paid a bonus of $60,000 in 1996 based on his achievements in 1995. The Compensation Committee considered, among other things, the clinical progress of brain-derived neurotrophic factor and neurotrophin-3, the Company's three announced preclinical programs, each of which was grounded in scientific expertise gained as a result of Regeneron's work in the area of neurotrophic factors, and aimed at diseases and conditions outside of the nervous system, a successful public offering of the Company's Common Stock, and other significant objectives that were attained during 1995. These important achievements were guided and managed by Dr. Schleifer and the Named Officers. 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. As described elsewhere in this Proxy Statement, the Board of Directors has adopted, subject to shareholder approval, certain amendments to the Long- Term Incentive Plan to bring the Long-Term Incentive Plan into compliance with Section 162(m).

The Board of Directors (the "Board"), on March 9, 1996, adopted, subject to shareholder approval, a series of amendments to the Long-Term Incentive Plan (the "Plan"), designed to enable awards made thereunder to comply with the exception for performance based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code") and any regulations thereunder ("Section 162(m)"). The Board believes that this amendment is reasonable and appropriate to meet the Company's objectives of attracting, motivating, and retaining officers, employees, and nonemployee service providers with appropriate experience and ability, and increasing the alignment of interests of officers, employees, and other grantees with those of the Company's shareholders. The Plan provides for the grant and award of Restricted Share Rights, Performance Unit Rights, Stock Options, Stock Appreciation Rights, Incentive Stock Rights (each as defined below). Section 162(m) of the Internal Revenue Code, in general, disallows the Company a federal income tax deduction for total remuneration in excess of $1 million paid to the chief executive officer or to any of the other four most highly compensated officers in any one year. However, Section 162(m) exempts performance-based compensation, such as stock option based compensation, if it is awarded under a shareholder-approved plan that meets certain requirements. The proposed amendments are intended to make awards of Restricted Share Rights (to the extent that the lapse of the relevant Restriction Period is subject to attainment of preestablished performance goals), Performance Unit Rights, Stock Options, and Stock Appreciation Rights granted thereunder to eligible employees constitute performance based compensation for purposes of Section 162(m). Capitalized terms not otherwise defined herein are as defined in the Plan. Description of Principal Features of the Long-Term Incentive Plan In 1990, the Company adopted, and in February 1991, June 1991, June 1994, and June 1995 the Company amended and restated the Plan, under which there are reserved for issuance a total of 3,900,000 shares of Common Stock. The Plan is administered by the Compensation Committee of the Board of Directors (the "Committee") comprised of three non-employee directors, each of whom is a "disinterested" person (as defined in Rule 16b-3 promulgated under Section 16 of the Securities Exchange Act of 1934, as amended) and an "outside director" (as defined in Section 162(m)). Company officers, employees, nonemployee directors, and other nonemployee service providers are eligible to participate in the Plan. Restricted Share Rights consist of a grant of shares of restricted Common Stock. A holder of restricted stock may vote and, if he or she remains in the service of the Company throughout the restricted period as defined in the Plan (the "Restricted Period"), may generally receive all dividends on all such shares. However, such holder may not transfer such shares except for limited circumstances 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 (other than as the result of such holder's death) the holder may be required under certain circumstances, to transfer and return to the Company such restricted stock, and may not receive dividends on such restricted stock. As amended, the Plan provides that (i) restrictions on restricted stock may, in the sole discretion of the Committee, lapse upon the achievement of certain preestablished performance goals based upon the criteria described below, and (ii) the maximum number of such performance based Restricted Share Rights that may be granted to an employee in any year is 200,000. Performance Unit Rights entitle the holder to receive either cash or shares of Common Stock, as determined by the Committee or Administrator, to the extent that preestablished performance goals, based upon the criteria described below, are achieved. Each Performance Unit Right granted is given a maximum value at the beginning of the performance period. The actual value of each right that may be distributed to the recipient is determined by the extent to which the predetermined objective is made. As amended, the Plan provides that the maximum unit value of Performance Unit Rights that may be granted to an employee in any year is $500,000. As amended, the Plan provides that performance goals will be based on one or more of the following criteria: (i) the attainment of certain target levels of, or a percentage increase in, after-tax or pre-tax profits of the Company including, without limitation, that attributable to continuing or other operations of the Company; (ii) the attainment of certain target ------------------------------ -page 13- levels of, or a specified increase in, operational cash flow of the Company; (iii) the achievement of a certain level of, reduction of, or other specified objectives with regard to limiting the level of increase in all or a portion of, the Company's bank debt or other long-term or short-term public or private debt or other similar financial obligations of the Company, which may be calculated net of such cash balances, and/or other offsets and adjustments as may be established by the Committee; (iv) the attainment of a specified percentage increase in earnings per share or earnings per share from continuing operations of the Company; (v) the attainment of certain target levels of, or a specified percentage increase in, revenues, net income or earnings before income tax of the Company; (vi) the attainment of certain target levels of, or a specified increase in, return on capital employed or return on investment; (vii) the attainment of certain target levels of, or a percentage increase in, after-tax or pre-tax return on shareholders' equity of the Company; (viii) the achievement of certain target levels of discovery or development of products, including, without limitation, the procurement of regulatory approval of new products; (ix) the achievement of certain target levels of sales of new products or licensing in or out of new drugs; and (x) the formation of joint ventures deals or the completion of other corporate transactions. In addition, the Plan provides that 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 Code Section 162(m), the Committee may: (i) designate additional business criteria on which the performance goals may be based or (ii) adjust, modify or amend the aforementioned business criteria. Stock options (which may be "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code")) entitle the holder to purchase shares of the Common Stock during a specified period at a purchase price of not less than 50% (100% in the case of incentive stock options) of the fair market value of the Common Stock on the day the option is granted. As amended, the Plan provides that the maximum number of shares of Common Stock for which Stock Options may be granted to an employee in any year is 500,000, except that such number is 1,000,000 with respect to the employee's initial year of employment with the Company. Stock Appreciation Rights may be granted only to recipients of Stock Options, and the number of shares that may be received pursuant to such Rights is limited to the number of shares subject to the Option. Stock Appreciation Rights may be exercised in lieu of purchasing shares under a related Option and entitles the holder, without payment to the Company, to a number of shares or cash, at the election of the Committee or the Administrator, determined by the increase, if any, in the market value of the shares under the Option between the dates of grant and exercise. As amended, the Plan provides that the maximum number of shares of Common Stock for which Stock Appreciation Rights may be granted to an employee in any year is 500,000, except that such number is 1,000,000 with respect to the employee's initial year of employment with the Company. Incentive Stock Rights are composed of Incentive Stock Units, each of which gives the holder the right to receive, without cash payment to the Company, one share of Common Stock, automatically, at the end of the relevant incentive periods fixed by the Committee or Administrator. Holders of Incentive Stock Rights receive payments equal to any cash dividends that are paid on the Common Stock. In the event of a change in control of the Company, as defined in the Plan, the vesting, exercisability and/or payout of Options and Rights may become accelerated, and the value of rights may be determined by the change in control price, as defined in the Plan. Approximately 219 employees and an indeterminate number of nonemployee service providers are eligible to participate in the Plan. As of December 31, 1995, options for 2,671,777 shares were held by 222 employees and nonemployee service providers at option prices averaging $6.148 per share and expiring during the period from January 2001 to December 2005. No Restricted Share Rights, Performance Unit Rights, or Stock Appreciation Rights, or Incentive Stock Rights have been granted under the Plan. Certain Federal Income Tax Consequences Set forth below is a discussion of certain federal income tax consequences with respect to Restricted Share Rights, Stock Options (including incentive stock options ("ISOs") and nonqualified stock options ("NQSOs")), and Stock Appreciation Rights ("SARs") that may be granted pursuant to the Plan. ------------------------------ -page 14- Restricted Share Rights A grant of Restricted Share Rights generally has no tax consequences at the time of grant. The participant will generally recognize ordinary income in an amount equal to the fair market value of Restricted Share Rights at the time such Restricted Share Rights are no longer subject to a substantial risk of forfeiture (as defined in the Code). The participant may, however, elect to be taxed at the date of grant of the award. The Company will be entitled to a deduction at the time when, and in the amount that, the employee recognizes ordinary income. A grant of Performance Unit Rights generally has no federal income tax consequences at the time of grant. The value of the shares and cash received is generally taxable to the participant upon receipt as ordinary income, and the Company will be entitled to a corresponding deduction at such time. Stock Options Nonqualified Stock Options. In the case of a NQSO, an option holder generally will not be taxed upon the grant of an option. Rather, at the time of exercise of such NQSO (and in the case of an untimely exercise of an ISO), the option holder will generally recognize ordinary income for federal income tax purposes in an amount equal to the excess of the then fair market value of the shares purchased over the option price. The Company will generally be entitled to a tax deduction at the time when, and in the amount that, the employee recognizes ordinary income. Incentive Stock Options. In the case of an ISO, an option holder will generally be in receipt of taxable income upon the disposition of the shares acquired upon exercise of the ISO, rather than upon the grant of the ISO or upon its timely exercise. If certain holding period requirements have been satisfied with respect to outstanding shares so acquired, taxable income will constitute long-term capital gain. The tax consequences of any untimely exercise of an ISO will be determined in accordance with the rules applicable to NQSOs. The amount by which the fair market value of the stock on the exercise date of an ISO exceeds the option price will be an item of tax adjustment for purposes of the "alternative minimum tax" imposed by Section 55 of the Code. An option holder who pays the option price upon exercise of an option, in whole or in part, by delivering already owned shares of the Company's Common Stock will generally not recognize gain or loss on the shares surrendered at the time of such delivery, except under certain circumstances relating to ISOs. Rather, such gain or loss recognition will generally occur upon disposition of the shares acquired in substitution for the shares surrendered. Stock Appreciation Rights A grant of Stock Appreciation Rights generally has no federal income tax consequences at the time of grant. Upon the exercise of stock appreciation rights, the value of the shares and cash received is generally taxable to the participant as ordinary income, and the Company will be entitled to a corresponding deduction. Incentive Stock Rights A grant of Incentive Stock Rights generally has no federal income tax consequences at the time of grant. The value of the shares received is generally taxable to the participant upon receipt as ordinary income, and the Company will be entitled to a corresponding deduction at such time.
