                                  AMGEN INC.

                AMENDED AND RESTATED 1991 EQUITY INCENTIVE PLAN


         1.   PURPOSE.

              (a)  The purpose of the Amended and Restated 1991 Equity
     Incentive Plan (the "Plan") is to provide a means by which employees
     or directors of and consultants to Amgen Inc., a Delaware corporation
     (the "Company"), and its Affiliates, as defined in paragraph 1(b),
     directly, or indirectly through Trusts, may be given an opportunity
     to benefit from increases in value of the stock of the Company
     through the granting of (i) incentive stock options, (ii)
     nonqualified stock options, (iii) stock bonuses, and (iv) rights to
     purchase restricted stock, all as defined below.

              (b)  The word "Affiliate" as used in the Plan means any
     parent corporation or subsidiary corporation of the Company, as those
     terms are defined in Sections 424(e) and (f), respectively, of the
     Internal Revenue Code of 1986, as amended (the "Code").

              (c)  The Company, by means of the Plan, seeks to retain the
     services of persons now employed by or serving as directors or
     consultants to the Company, to secure and retain the services of
     persons capable of filling such positions, and to provide incentives
     for such persons to exert maximum efforts for the success of the
     Company.

              (d)  The Company intends that the rights issued under the
     Plan ("Stock Awards") shall, in the discretion of the Board of
     Directors of the Company (the "Board") or any committee to which
     responsibility for administration of the Plan has been delegated
     pursuant to paragraph 2(c), be either (i) stock options granted
     pursuant to Sections 5 or 6 hereof, including incentive stock options
     as that term is used in Section 422 of the Code ("Incentive Stock
     Options"), or options which do not qualify as Incentive Stock Options
     ("Nonqualified Stock Options") (together hereinafter referred to as
     "Options"), or (ii) stock bonuses or rights to purchase restricted
     stock granted pursuant to Section 7 hereof.

              (e)  The word "Trust" as used in the Plan shall mean a
     trust created for the benefit of the employee, director or
     consultant, his or her spouse, or members of their immediate family.
     The word optionee shall mean the person to whom the option is granted
     or the employee, director or consultant for whose benefit the option
     is granted to a Trust, as the context shall require.

         2.   ADMINISTRATION.

              (a)  The Plan shall be administered by the Board unless and
     until the Board delegates administration to a committee, as provided
     in paragraph 2(c).


              (b)  The Board shall have the power, subject to, and within
                                       1
        
     the limitations of, the express provisions of the Plan:

                   (1)  To determine from time to time which of the
     persons eligible under the Plan shall be granted Stock Awards; when
     and how Stock Awards shall be granted; whether a Stock Award will be
     an Incentive Stock Option, a Nonqualified Stock Option, a stock
     bonus, a right to purchase restricted stock, or a combination of the
     foregoing; the provisions of each Stock Award granted (which need not
     be identical), including the time or times when a person shall be
     permitted to purchase or receive stock pursuant to a Stock Award; and
     the number of shares with respect to which Stock Awards shall be
     granted to each such person.

                   (2)  To construe and interpret the Plan and Stock
     Awards granted under it, and to establish, amend and revoke rules and
     regulations for its administration.  The Board, in the exercise of
     this power, may correct any defect, omission or inconsistency in the
     Plan or in any Stock Award, in a manner and to the extent it shall
     deem necessary or expedient to make the Plan fully effective.

                   (3)  To amend the Plan as provided in Section 15.

                   (4)  Generally, to exercise such powers and to perform
     such acts as the Board deems necessary or expedient to promote the
     best interests of the Company.

              (c)  The Board may delegate administration of the Plan to a
     committee composed of not fewer than two (2) members of the Board
     (the "Committee").  One or more of these members may be non-employee
     directors and outside directors, if required and as defined by the
     provisions of paragraphs 2(d) and 2(e).  If administration is
     delegated to a Committee, the Committee shall have, in connection
     with the administration of the Plan, the powers theretofore possessed
     by the Board (except amendment of Section 6 or the options granted
     thereunder shall only be by action taken by the Board or a committee
     of one or more members of the Board to which such authority has been
     specifically delegated by the Board), subject, however, to such
     resolutions, not inconsistent with the provisions of the Plan, as may
     be adopted from time to time by the Board.  Notwithstanding anything
     else in this paragraph 2(c) to the contrary, at any time the Board or
     the Committee may delegate to a committee of one or more members of
     the Board the authority to grant or amend options to all employees,
     directors or consultants or any portion or class thereof.

              (d)  The term "non-employee director" shall mean a member
     of the Board who (i) is not currently an officer of the Company or a
     parent or subsidiary of the Company (as defined in Rule 16a-1(f)
     promulgated by the Securities and Exchange Commission under Section
     16 of the Securities Exchange Act of 1934, as amended (the "Exchange
     Act")) or an employee of the Company or a parent or subsidiary of the
     Company; (ii) does not receive compensation from the Company or a
     parent or subsidiary of the Company for services rendered in any
     capacity other than as a member of the Board (including a consultant)
     in an amount required to be disclosed to the Company's stockholders
     under Rule 404 of Regulation S-K promulgated by the Securities and
     Exchange Commission ("Rule 404"); (iii) does not possess an interest
     in any other transaction required to be disclosed under Rule 404; or
     (iv) is not engaged in a business relationship required to be
                                       2
     
     disclosed under Rule 404, as all of these provisions are interpreted
     by the Securities and Exchange Commission under Rule 16b-3
     promulgated under the Exchange Act.

              (e)  The term "outside director," as used in this Plan,
     shall mean an administrator of the Plan, whether a member of the
     Board or of any Committee to which responsibility for administration
     of the Plan has been delegated pursuant to paragraph 2(c), who is
     considered to be an "outside director" in accordance with the rules,
     regulations or interpretations of Section 162(m) of the Code.

              (f)  Any requirement that an administrator of the Plan be a
     "non-employee director" or "outside director" shall not apply if the
     Board or the Committee expressly declares that such requirement shall
     not apply.

         3.   SHARES SUBJECT TO THE PLAN.

              (a)  Subject to the provisions of Section 12 relating to
     adjustments upon changes in stock, the stock that may be issued
     pursuant to Stock Awards granted under the Plan shall not exceed in
     the aggregate Forty Eight Million (48,000,000) shares of the
     Company's $.0001 par value common stock (the "Common Stock").  If any
     Stock Award granted under the Plan shall for any reason expire or
     otherwise terminate without having been exercised in full, the Common
     Stock not purchased under such Stock Award shall again become
     available for the Plan.  Shares repurchased by the Company pursuant
     to any repurchase rights reserved by the Company pursuant to the Plan
     shall not be available for subsequent issuance under the Plan.

              (b)  The Common Stock subject to the Plan may be unissued
     shares or reacquired shares, bought on the market or otherwise.

              (c)  An Incentive Stock Option may be granted to an
     eligible person under the Plan only if the aggregate fair market
     value (determined at the time the Incentive Stock Option is granted)
     of the Common Stock with respect to which incentive stock options (as
     defined by the Code) are exercisable for the first time by such
     optionee during any calendar year under all such plans of the Company
     and its Affiliates does not exceed one hundred thousand dollars
     ($100,000).  If it is determined that an entire Option or any portion
     thereof does not qualify for treatment as an Incentive Stock Option
     by reason of exceeding such maximum, such Option or the applicable
     portion shall be considered a Nonqualified Stock Option.

         4.   ELIGIBILITY.

              (a)  Incentive Stock Options may be granted only to
     employees (including officers) of the Company or its Affiliates.  A
     director of the Company shall not be eligible to receive Incentive
     Stock Options unless such director is also an employee of the Company
     or any Affiliate.  Stock Awards other than Incentive Stock Options
     may be granted to employees (including officers) or directors of or
     consultants to the Company or any Affiliate or to Trusts of any such
     employee, director or consultant.

              (b)  A director shall in no event be eligible for the
     benefits of the Plan (other than from a Director NQSO under Section 6
                                       3
     
     of the Plan) unless and until such director is expressly declared
     eligible to participate in the Plan by action of the Board or the
     Committee, and only if, at any time discretion is exercised by the
     Board or the Committee in the selection of a director as a person to
     whom Stock Awards may be granted, or in the determination of the
     number of shares which may be covered by Stock Awards granted to a
     director, the Plan complies with the requirements of Rule 16b-3
     promulgated under the Exchange Act, as from time to time in effect.
     The Board shall otherwise comply with the requirements of Rule 16b-3
     promulgated under the Exchange Act, as from time to time in effect.
     Notwithstanding the foregoing, the restrictions set forth in
     this paragraph 4(b) shall not apply if the Board or Committee
     expressly declares that such restrictions shall not apply.

              (c)  No person shall be eligible for the grant of an
     Incentive Stock Option under the Plan if, at the time of grant, such
     person owns (or is deemed to own pursuant to Section 424(d) of the
     Code) stock possessing more than ten percent (10%) of the total
     combined voting power of all classes of stock of the Company or of
     any of its Affiliates unless the exercise price of such Incentive
     Stock Option is at least one hundred and ten percent (110%) of the
     fair market value of the Common Stock at the date of grant and the
     Incentive Stock Option is not exercisable after the expiration of
     five (5) years from the date of grant.

              (d)  Stock Awards shall be limited to a maximum of 500,000
     shares of Common Stock per person per calendar year, which reflects
     the Company's two for one stock split in August 1995.

         5.   TERMS OF DISCRETIONARY STOCK OPTIONS.

              An option granted pursuant to this Section 5 (a
     "Discretionary Stock Option") shall be in such form and shall contain
     such terms and conditions as the Board or the Committee shall deem
     appropriate.  The provisions of separate Options need not be
     identical, but each Option shall include (through incorporation of
     provisions hereof by reference in the Option or otherwise) the
     substance of each of the following provisions:

              (a)  No Option shall be exercisable after the expiration of
     ten (10) years from the date it was granted.

              (b)  The exercise price of each Incentive Stock Option and
     each Nonqualified Stock Option shall be not less than one hundred
     percent (100%) of the fair market value of the Common Stock subject
     to the Option on the date the Option is granted.


              (c)  The purchase price of Common Stock acquired pursuant
     to an Option shall be paid, to the extent permitted by applicable
     statutes and regulations, either:  (i) in cash at the time the Option
     is exercised; or (ii) at the discretion of the Board or the
     Committee, either at the time of grant or exercise of the Option (A)
     by delivery to the Company of shares of Common Stock that have been
     held for the period required to avoid a charge to the Company's
     reported earnings and valued at the fair market value on the date of
     exercise, (B) according to a deferred payment or other arrangement
     with the person to whom the Option is granted or to whom the Option
                                       4
     
     is transferred pursuant to paragraph 5(d), or (C) in any other form
     of legal consideration that may be acceptable to the Board or the
     Committee in their discretion; including but not limited to payment
     of the purchase price pursuant to a program developed under
     Regulation T as promulgated by the Federal Reserve Board which
     results in the receipt of cash (or a check) by the Company before
     Common Stock is issued or the receipt of irrevocable instruction to
     pay the aggregate exercise price of the Company from the sales
     proceeds before Common Stock is issued.

         In the case of any deferred payment arrangement, interest shall
     be payable at least annually and shall be charged at not less than
     the minimum rate of interest necessary to avoid the treatment as
     interest, under any applicable provisions of the Code, of any amounts
     other than amounts stated to be interest under the deferred payment
     arrangement.

               (d)  An Option granted to a natural person shall be
     exercisable during the lifetime of such person only by such person,
     provided that such person during such person's lifetime may designate
     a Trust to be such person's beneficiary with respect to any Incentive
     Stock Options granted after February 25, 1992 and with respect to any
     Nonqualified Stock Options, and such beneficiary shall, after the
     death of the person to whom the Option was granted, have all the
     rights that such person has while living, including the right to
     exercise the Option.  In the absence of such designation, after the
     death of the person to whom the Option is granted, the Option shall
     be exercisable by the person or persons to whom the optionee's rights
     under such Option pass by will or by the laws of descent and
     distribution.

              (e)  The total number of shares of Common Stock subject to
     an Option may, but need not, be allotted in periodic installments
     (which may, but need not, be equal).  From time to time during each
     of such installment periods, the Option may become exercisable
     ("vest") with respect to some or all of the shares allotted to that
     period, and may be exercised with respect to some or all of the
     shares allotted to such period and/or any prior period as to which
     the Option was not fully exercised.  During the remainder of the term
     of the Option (if its term extends beyond the end of the installment
     periods), the Option may be exercised from time to time with respect
     to any shares then remaining subject to the Option.  The provisions
     of this paragraph 5(e) are subject to any Option provisions governing
     the minimum number of shares as to which an Option may be exercised.

              (f)  The Company may require any optionee, or any person to
     whom an Option is transferred under paragraph 5(d), as a condition of
     exercising any such Option: (i) to give written assurances
     satisfactory to the Company as to such person's knowledge and
     experience in financial and business matters and/or to employ a
     purchaser representative who has such knowledge and experience in
     financial and business matters, and that such person is capable of
     evaluating, alone or together with the purchaser representative, the
     merits and risks of exercising the Option; and (ii) to give written
     assurances satisfactory to the Company stating that such person is
     acquiring the Common Stock subject to the Option for such person's
     own account and not with any present intention of selling or
     otherwise distributing the Common Stock.  These requirements, and any
                                       5
     
     assurances given pursuant to such requirements, shall be inoperative
     if: (x) the issuance of the shares upon the exercise of the Option
     has been registered under a then currently effective registration
     statement under the Securities Act of 1933, as amended (the
     "Securities Act"); or (y) as to any particular requirement, a
     determination is made by counsel for the Company that such
     requirement need not be met in the circumstances under the then
     applicable securities law.

              (g)  An Option shall terminate three (3) months after
     termination of the optionee's employment or relationship as a
     consultant or director with the Company or an Affiliate, unless: (i)
     such termination is due to the optionee's permanent and total
     disability, within the meaning of Section 422(c)(6) of the Code, in
     which case the Option may, but need not, provide that it may be
     exercised at any time within one (1) year following such termination
     of employment or relationship as a consultant or director; (ii) the
     optionee dies while in the employ of or while serving as a consultant
     or director to the Company or an Affiliate, or within not more than
     three (3) months after termination of such employment or relationship
     as a consultant or director, in which case the Option may, but need
     not, provide that it may be exercised at any time within eighteen
     (18) months following the death of the optionee by the person or
     persons to whom the optionee's rights under such Option pass by will
     or by the laws of descent and distribution;  or (iii) the Option by
     its term specifies either (A) that it shall terminate sooner than
     three (3) months after termination of the optionee's employment or
     relationship as a consultant or director with the Company or an
     Affiliate; or (B) that it may be exercised more than three (3) months
     after termination of the optionee's employment or relationship as a
     consultant or director with the Company or an Affiliate.  This
     paragraph 5(g) shall not be construed to extend the term of any
     Option or to permit anyone to exercise the Option after expiration of
     its term, nor shall it be construed to increase the number of shares
     as to which any Option is exercisable from the amount exercisable on
     the date of termination of the optionee's employment or relationship
     as a consultant or director.

              (h)  The Option may, but need not, include a provision
     whereby the optionee may elect at any time during the term of the
     optionee's employment or relationship as a consultant or director
     with the Company or any Affiliate to exercise the Option as to any
     part or all of the shares subject to the Option prior to the stated
     vesting dates of the Option.  Any shares so purchased from any
     unvested installment or Option may be subject to a repurchase right
     in favor of the Company or to any other restriction the Board or the
     Committee determines to be appropriate.

              (i)  To the extent provided by the terms of an Option, each
     optionee may satisfy any federal, state or local tax withholding
     obligation relating to the exercise of such Option by any of the
     following means or by a combination of such means: (i) tendering a
     cash payment; (ii) authorizing the Company to withhold from the
     shares of the Common Stock otherwise issuable to the optionee as a
     result of the exercise of the Option a number of shares having a fair
     market value less than or equal to the amount of the withholding tax
     obligation; or (iii) delivering to the Company owned and unencumbered
     shares of the Common Stock having a fair market value less than or
                                       6
     
     equal to the amount of the withholding tax obligation.

              (j)  Without in any way limiting the authority of the Board
     or Committee to make or not to make grants of Discretionary Stock
     Options under this Section 5, the Board or Committee shall have the
     authority (but not an obligation) to include as part of any Option
     agreement a provision entitling the optionee to a further Option (a
     "Re-Load Option") in the event the optionee exercises the Option
     evidenced by the Option agreement, in whole or in part, by
     surrendering other shares of Common Stock in accordance with this
     Plan and the terms and conditions of the Option agreement.  Any such
     Re-Load Option (i) shall be for a number of shares equal to the
     number of shares surrendered as part or all of the exercise price of
     such Option; (ii) shall have an expiration date which is the same as
     the expiration date of the Option the exercise of which gave rise to
     such Re-Load Option; and (iii) shall have an exercise price which is
     equal to one hundred percent (100%) of the fair market value of the
     Common Stock subject to the Re-Load Option on the date of exercise of
     the original Option or, in the case of a Re-Load Option which is an
     Incentive Stock Option and which is granted to a 10% stockholder (as
     defined in paragraph 4(c)), shall have an exercise price which is
     equal to one hundred and ten percent (110%) of the fair market value
     of the Common Stock subject to the Re-Load Option on the date of
     exercise of the original Option.

                   Any such Re-Load Option may be an Incentive Stock
     Option or a Nonqualified Stock Option, as the Board or Committee may
     designate at the time of the grant of the original Option, provided,
     however, that the designation of any Re-Load Option as an Incentive
     Stock Option shall be subject to the one hundred thousand dollars
     ($100,000) annual limitation on exercisability of Incentive Stock
     Options described in paragraph 3(c) of the Plan and in Section 422(d)
     of the Code.  There shall be no Re-Load Option on a Re-Load Option.
     Any such Re-Load Option shall be subject to the availability of
     sufficient shares under paragraph 3(a) and shall be subject to such
     other terms and conditions as the Board or Committee may determine.

         6.   TERMS OF NON-DISCRETIONARY OPTIONS.

              (a)  On January 27 of each year commencing January 27,
     1998, each person who is at that time an Eligible Director of the
     Company, (as defined in paragraph 6(k)), shall automatically be
     granted under the Plan, without further action by the Company, the
     Board, or the Company's stockholders, a Nonqualified Stock Option (a
     "Director NQSO") to purchase four thousand (4,000) shares of Common
     Stock on the terms and conditions set forth herein.  An Eligible
     Director may designate that such Director NQSO be granted in the name
     of a Trust instead of in the name of such Eligible Director.  The
     number of shares to be granted hereunder shall not be adjusted as
     provided for in Section 12.  The Director NQSO shall be on the terms
     and conditions set forth herein and should the date of grant set
     forth above be a Saturday, Sunday or legal holiday, such grant shall
     be made on the next business day.

              (b)  Each person who, after January 27 of any year
     commencing January 27, 1998 and prior to November 1 of any year,
     becomes an Eligible Director, shall, upon the date such person
     becomes an Eligible Director, automatically be granted under the
                                       7
     
     Plan, without further action by the Company, the Board, or the
     Company's stockholders, a Director NQSO to purchase fifteen thousand
     (15,000) shares of Common Stock on the terms and conditions set forth
     herein.  An Eligible Director may designate that such Director NQSO
     be granted in the name of a Trust instead of in the name of such
     Eligible Director.  The number of shares to be granted under this
     Section 6 shall not be adjusted as provided for in Section 12.  The
     Director NQSO shall be on the terms and conditions set forth herein
     and should the date of grant set forth above be a Saturday, Sunday or
     legal holiday, such grant shall be made on the next business day.

              (c)  Each Director NQSO granted pursuant to this Section 6
     (or any Director Re-Load Option granted pursuant to paragraph 6(j))
     shall be in such form and shall contain such terms and conditions as
     the Board or the Committee shall deem appropriate.  The provisions of
     separate Director NQSO's need not be identical, but each Director
     NQSO shall include (through incorporation of provisions hereof by
     reference in the Director NQSO or otherwise) the substance of each of
     the following provisions as set forth in paragraphs 6(d) through
     6(j), inclusive.

              (d)  The term of each Director NQSO shall be ten (10) years
     from the date it was granted.

              (e)  The exercise price of each Director NQSO shall be one
     hundred percent (100%) of the fair market value of the Common Stock
     subject to such Director NQSO on the date such Director NQSO is
     granted.

              (f)  The purchase price of Common Stock acquired pursuant
     to a Director NQSO shall be paid, to the extent permitted by
     applicable statutes and regulations, either (i) in cash at the time
     the Director NQSO is exercised; (ii) by delivery to the Company of
     shares of Common Stock that have been held for the period required to
     avoid a charge to the Company's reported earnings and valued at their
     fair market value on the date of exercise; or (iii) pursuant to a
     program developed under Regulation T as promulgated by the Federal
     Reserve Board which results in the receipt of cash (or a check) by
     the Company before Common Stock is issued or the receipt of
     irrevocable instructions to pay the aggregate exercise price to the
     Company from the sales proceeds before Common Stock is issued.

              (g)  A Director NQSO shall be exercisable during the
     lifetime of the Eligible Director with respect to whom it was granted
     only by the person to whom it was granted (whether the Eligible
     Director or a Trust), provided that such person during the Eligible
     Director's lifetime may designate a Trust to be a beneficiary with
     respect to the Director NQSO, and such beneficiary shall, after the
     death of the Eligible Director to whom the Director NQSO was granted,
     have all of the rights designated for such beneficiary.  In the
     absence of such designation, after the death of the Eligible Director
     with respect to whom the Director NQSO was granted, if such Director
     NQSO was granted to the Eligible Director, the Director NQSO shall be
     exercisable by the person or persons to whom the optionee's rights
     under such option pass by will or by the laws of descent and
     distribution.

              (h)  A Director NQSO shall not vest with respect to an
                                       8
     
     Eligible Director, or the affiliate of such Eligible Director, as the
     case may be, (i) unless the Eligible Director, has, at the date of
     grant, provided three (3) years of prior continuous service as an
     Eligible Director, or (ii) until the date upon which such Eligible
     Director has provided one year of continuous service as an Eligible
     Director following the date of grant of such Director NQSO, whereupon
     such Director NQSO shall become fully vested and exercisable in
     accordance with its terms.

              (i)  The Company may require any optionee under this
     Section 6, or any person to whom a Director NQSO is transferred under
     paragraph 6(g), as a condition of exercising any such option:  (i) to
     give written assurances satisfactory to the Company as to such
     person's knowledge and experience in financial and business matters
     and/or to employ a purchaser representative who has such knowledge
     and experience in financial and business matters, and that such
     person is capable of evaluating, alone or together with the purchaser
     representative, the merits and risks of exercising the Director NQSO;
     and (ii) to give written assurances satisfactory to the Company
     stating that such person is acquiring the Common Stock subject to the
     Director NQSO for such person's own account and not with any present
     intention of selling or otherwise distributing the stock.  These
     requirements, and any assurances given pursuant to such requirements,
     shall be inoperative if (i) the issuance of the shares upon the
     exercise of the Director NQSO has been registered under a then
     currently effective registration statement under the Securities Act
     of 1933, as amended (the "Securities Act"), or (ii), as to any
     particular requirement, a determination is made by counsel for the
     Company that such requirement need not be met in the circumstances
     under the then applicable securities laws.

              (j)  Subject to the last sentence of this paragraph 6(j),
     each Director NQSO shall include a provision entitling the optionee
     to a further Nonqualified Stock Option (a "Director Re-Load Option")
     in the event the optionee exercises the Director NQSO evidenced by
     the Director NQSO grant, in whole or in part, by surrendering other
     shares of Common Stock in accordance with the Plan and the terms of
     the Director NQSO grant.  Any such Director Re-Load Option (i) shall
     be for a number of shares equal to the number of shares surrendered
     as part or all of the exercise price of the original Director NQSO;
     (ii) shall have an expiration date which is the same as the
     expiration date of the original Director NQSO; and (iii) shall have
     an exercise price which is equal to one hundred percent (100%) of the
     fair market value of the Common Stock subject to the Director Re-Load
     Option on the date of exercise of the original Director NQSO.  Any
     such Director Re-Load Option shall be subject to the availability of
     sufficient shares under paragraph 3(a).  There shall be no Director
     Re-Load Option on a Director Re-Load Option.


              (k)  For purposes of this Section 6, the term "Eligible
     Director" shall mean a member of the Board who is not an employee of
     the Company or any Affiliate, and the term "affiliate" shall mean a
     person that directly or indirectly controls, is controlled by, or is
     under common control with, the Eligible Director.

         7.   TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

                                       9
     
              Each stock bonus or restricted stock purchase agreement
     shall be in such form and shall contain such terms and conditions as
     the Board or the Committee shall deem appropriate.  The terms and
     conditions of stock bonus or restricted stock purchase agreements may
     change from time to time, and the terms and conditions of separate
     agreements need not be identical, but each stock bonus or restricted
     stock purchase agreement shall include (through incorporation of
     provisions hereof by reference in the agreement or otherwise) the
     substance of each of the following provisions as appropriate:

              (a)  The purchase price under each stock purchase agreement
     shall be such amount as the Board or Committee shall determine and
     designate in such agreement.  Notwithstanding the foregoing, the
     Board or the Committee may determine that eligible participants in
     the Plan may be awarded stock pursuant to a stock bonus agreement in
     consideration for past services actually rendered to the Company or
     for its benefit.

              (b)  No rights under a stock bonus or restricted stock
     purchase agreement shall be assignable by any participant under the
     Plan, either voluntarily or by operation of law, except where such
     assignment is required by law or expressly authorized by the terms of
     the applicable stock bonus or restricted stock purchase agreement.

              (c)  The purchase price of stock acquired pursuant to a
     stock purchase agreement shall be paid either:  (i) in cash at the
     time of purchase; (ii) at the discretion of the Board or the
     Committee, according to a deferred payment or other arrangement with
     the person to whom the Common Stock is sold; or (iii) in any other
     form of legal consideration that may be acceptable to the Board or
     the Committee in their discretion; including but not limited to
     payment of the purchase price pursuant to a program developed under
     Regulation T as promulgated by the Federal Reserve Board which
     results in the receipt of cash (or a check) by the Company before
     Common Stock is issued or the receipt of irrevocable instruction to
     pay the aggregate exercise price of the Company from the sales
     proceeds before Common Stock is issued.  Notwithstanding the
     foregoing, the Board or the Committee to which administration of the
     Plan has been delegated may award Common Stock pursuant to a stock
     bonus agreement in consideration for past services actually rendered
     to the Company or for its benefit.

              (d)  Shares of Common Stock sold or awarded under the Plan
     may, but need not, be subject to a repurchase option in favor of the
     Company in accordance with a vesting schedule to be determined by the
     Board or the Committee.

              (e)  In the event a person ceases to be an employee of or
     ceases to serve as a director or consultant to the Company or an
     Affiliate, the Company may repurchase or otherwise reacquire any or
     all of the shares of Common Stock held by that person which have not
     vested as of the date of termination under the terms of the stock
     bonus or restricted stock purchase agreement between the Company and
     such person.

         8.   CANCELLATION AND RE-GRANT OF OPTIONS.

              The Board or the Committee shall have the authority to
                                      10
     
     effect, at any time and from time to time, with the consent of the
     affected holders of Options, (i) the repricing of any outstanding
     Options under the Plan and/or (ii) the cancellation of any
     outstanding Options under the Plan and the grant in substitution
     therefor of new Options under the Plan covering the same or different
     numbers of shares of Common Stock, but having an exercise price per
     share not less than one hundred percent (100%) of the fair market
     value per share of Common Stock on the new grant date or, in the case
     of a 10% stockholder (as defined in paragraph 4(c)), not less than
     one hundred and ten percent (110%) of the fair market value per share
     of Common Stock on the new grant date.

         9.   COVENANTS OF THE COMPANY.

              (a)  During the terms of the Stock Awards granted under the
     Plan, the Company shall keep available at all times the number of
     shares of Common Stock required to satisfy such Stock Awards up to
     the number of shares of Common Stock authorized under the Plan.

              (b)  The Company shall seek to obtain from each regulatory
     commission or agency having jurisdiction over the Plan such authority
     as may be required to issue and sell shares of Common Stock under the
     Stock Awards granted under the Plan; provided, however, that this
     undertaking shall not require the Company to register under the
     Securities Act either the Plan, any Stock Award granted under the
     Plan or any Common Stock issued or issuable pursuant to any such
     Stock Award.  If, after reasonable efforts, the Company is unable to
     obtain from any such regulatory commission or agency the authority
     that counsel for the Company deems necessary for the lawful issuance
     and sale of Common Stock under the Plan, the Company shall be
     relieved from any liability for failure to issue and sell Common
     Stock upon exercise of such Stock Awards unless and until such
     authority is obtained.

         10.  USE OF PROCEEDS FROM COMMON STOCK.

              Proceeds from the sale of Common Stock pursuant to Stock
     Awards granted under the Plan shall constitute general funds of the
     Company.

         11.  MISCELLANEOUS.

               (a)  The Board or Committee shall have the power to
     accelerate the time during which a Stock Award may be exercised or
     the time during which a Stock Award or any part thereof will vest,
     notwithstanding the provisions in the Stock Award stating the time
     during which it may be exercised or the time during which it will
     vest.  Each Discretionary Stock Option providing for vesting pursuant
     to paragraph 5(e) shall also provide that if the employee's
     employment or a director's or consultant's affiliation with the
     Company is terminated by reason of death or disability (within the
     meaning of Title II or XVI of the Social Security Act and as
     determined by the Social Security Administration), the vesting
     schedule of Discretionary Stock Options granted to such employee,
     director or consultant or to the Trusts of such employee, director or
     consultant shall be accelerated by twelve months for each full year
     the employee has been employed by or the director or consultant has
     been affiliated with the Company.  Discretionary Stock Options
                                      11
     
     granted under the Plan that are outstanding on February 25, 1992,
     shall be amended to include the accelerated vesting upon death
     provided for in the preceding sentence of this paragraph 11(a) and
     Discretionary Stock Options granted under the Plan that are
     outstanding on June 18, 1996, shall be amended to include the
     accelerated vesting upon disability provided for in the preceding
     sentence of this paragraph 11(a).

              (b)  Neither an optionee nor any person to whom an Option
     is transferred under the provisions of the Plan shall be deemed to be
     the holder of, or to have any of the rights of a holder with respect
     to, any shares subject to such Option unless and until such person
     has satisfied all requirements for exercise of the Option pursuant to
     its terms.

              (c)  Nothing in the Plan or any instrument executed or
     Stock Award granted pursuant thereto shall confer upon any eligible
     employee, consultant, director, optionee or holder of Stock Awards
     under the Plan any right to continue in the employ of the Company or
     any Affiliate or to continue acting as a consultant or director or
     shall affect the right of the Company or any Affiliate to terminate
     the employment or consulting relationship or directorship of any
     eligible employee, consultant, director, optionee or holder of Stock
     Awards under the Plan with or without cause.  In the event that a
     holder of Stock Awards under the Plan is permitted or otherwise
     entitled to take a leave of absence, the Company shall have the
     unilateral right to (i) determine whether such leave of absence will
     be treated as a termination of employment or relationship as
     consultant or director for purposes hereof, and (ii) suspend or
     otherwise delay the time or times at which exercisability or vesting
     would otherwise occur with respect to any outstanding Stock Awards
     under the Plan.

         12.  ADJUSTMENTS UPON CHANGES IN COMMON STOCK.

              If any change is made in the Common Stock subject to the
     Plan, or subject to any Stock Award granted under the Plan (through
     merger, consolidation, reorganization, recapitalization, stock
     dividend, dividend in property other than cash, stock split,
     liquidating dividend, combination of shares, exchange of shares,
     change in corporate structure or other transaction not involving the
     receipt of consideration by the Company), the Plan and outstanding
     Stock Awards will be appropriately adjusted in the class(es) and
     maximum number of shares subject to the Plan, the maximum number of
     shares which may be granted to a participant in a calendar year, and
     the class(es) and number of shares and price per share of stock
     subject to outstanding Stock Awards; provided, that the minimum and
     maximum number of shares of Common Stock to be granted as provided
     for in paragraphs 6(a) and 6(b) shall not be so adjusted.  Such
     adjustment shall be made by the Board or the Committee, the
     determination of which shall be final, binding and conclusive.  (The
     conversion of any convertible securities of the Company shall not be
     treated as a "transaction not involving the receipt of
     consideration".)

         13.  CHANGE OF CONTROL.

               (a)  Notwithstanding anything to the contrary in this Plan,
                                      12
     
     in the event of a Change in Control (as hereinafter defined), then,
     to the extent permitted by applicable law:  (i) the time during which
     Stock Awards become vested shall automatically be accelerated so that
     the unvested portions of all Stock Awards shall be vested prior to
     the Change in Control and (ii) the time during which the Options may
     be exercised shall automatically be accelerated to prior to the
     Change in Control.  Upon and following the acceleration of the
     vesting and exercise periods, at the election of the holder of the
     Stock Award, the Stock Award may be:  (x) exercised (with respect to
     Options) or, if the surviving or acquiring corporation agrees to
     assume the Stock Awards or substitute similar stock awards, (y)
     assumed; or (z) replaced with substitute stock awards.  Options not
     exercised, substituted or assumed prior to or upon the Change in
     Control shall be terminated.

              (b)  For purposes of the Plan, a "Change of Control" shall
     be deemed to have occurred at any of the following times:

                   (i)  upon the acquisition (other than from the
     Company) by any person, entity or "group," within the meaning of
     Section 13(d)(3) or 14(d)(2) of the Exchange Act (excluding, for this
     purpose, the Company or its affiliates, or any employee benefit plan
     of the Company or its affiliates which acquires beneficial ownership
     of voting securities of the Company), of beneficial ownership (within
     the meaning of Rule 13d-3 promulgated under the Exchange Act) of
     fifty percent (50%) or more of either the then outstanding shares of
     Common Stock or the combined voting power of the Company's then
     outstanding voting securities entitled to vote generally in the
     election of directors; or

                   (ii)  at the time individuals who, as of April 2,
     1991, constitute the Board (the "Incumbent Board") cease for any
     reason to constitute at least a majority of the Board, provided that
     any person becoming a director subsequent to April 2, 1991, whose
     election, or nomination for election by the Company's stockholders,
     was approved by a vote of at least a majority of the directors then
     comprising the Incumbent Board (other than an election or nomination
     of an individual whose initial assumption of office is in connection
     with an actual or threatened election contest relating to the
     election of the Directors of the Company, as such terms are used in
     Rule 14a-11 of Regulation 14A promulgated under the Exchange Act)
     shall be, for purposes of the Plan, considered as though such person
     were a member of the Incumbent Board; or

                   (iii)  immediately prior to the consummation by the
     Company of a reorganization, merger, consolidation, (in each case,
     with respect to which persons who were the stockholders of the
     Company immediately prior to such reorganization, merger or
     consolidation do not, immediately thereafter, own more than fifty
     percent (50%) of the combined voting power entitled to vote generally
     in the election of directors of the reorganized, merged or
     consolidated company's then outstanding voting securities) or a
     liquidation or dissolution of the Company or of the sale of all or
     substantially all of the assets of the Company; or

                   (iv)  the occurrence of any other event which the
     Incumbent Board in its sole discretion determines constitutes a
     Change of Control.
                                      13
     

         14.  QUALIFIED DOMESTIC RELATIONS ORDERS.


               (a)  Anything in the Plan to the contrary notwithstanding,
     rights under Stock Awards may be assigned to an Alternate Payee to
     the extent that a QDRO so provides.  (The terms "Alternate Payee" and
     "QDRO" are defined in paragraph 14(c) below.)  The assignment of a
     Stock Award to an Alternate Payee pursuant to a QDRO shall not be
     treated as having caused a new grant.  The transfer of an Incentive
     Stock Option to an Alternate Payee may, however, cause it to fail to
     qualify as an Incentive Stock Option.  If a Stock Award is assigned
     to an Alternate Payee, the Alternate Payee generally has the same
     rights as the grantee under the terms of the Plan; provided however,
     that (i) the Stock Award shall be subject to the same vesting terms
     and exercise period as if the Stock Award were still held by the
     grantee, (ii) an Alternate Payee may not transfer a Stock Award and
     (iii) an Alternate Payee is ineligible for Re-Load Options described
     at paragraph 5(j) or Director Re-Load Options described at paragraph
     6(j).

               (b)  In the event of the Plan administrator's receipt of a
     domestic relations order or other notice of adverse claim by an
     Alternate Payee of a grantee of a Stock Award, transfer of the
     proceeds of the exercise of such Stock Award, whether in the form of
     cash, stock or other property, may be suspended.  Such proceeds shall
     thereafter be transferred pursuant to the terms of a QDRO or other
     agreement between the grantee and Alternate Payee.  A grantee's
     ability to exercise a Stock Award may be barred if the Plan
     administrator receives a court order directing the Plan administrator
     not to permit exercise.

              (c)  The word "QDRO" as used in the Plan shall mean a court
     order (i) that creates or recognizes the right of the spouse, former
     spouse or child (an "Alternate Payee") of an individual who is
     granted a Stock Award to an interest in such Stock Award relating to
     marital property rights or support obligations and (ii) that the
     administrator of the Plan determines would be a "qualified domestic
     relations order," as that term is defined in section 414(p) of the
     Code and section 206(d) of the Employee Retirement Income Security
     Act ("ERISA"), but for the fact that the Plan is not a plan described
     in section 3(3) of ERISA.

         15.  AMENDMENT OF THE PLAN.

              (a)  The Board at any time, and from time to time, may
     amend the Plan.  However, except as provided in Section 12 relating
     to adjustments upon changes in the Common Stock, no amendment shall
     be effective unless approved by the stockholders of the Company
     within twelve (12) months before or after the adoption of the
     amendment, where the amendment will:

                   (i)  increase the number of shares reserved for Stock
     Awards under the Plan;

                  (ii)  modify the requirements as to eligibility for
     participation in the Plan (to the extent such modification requires
     stockholder approval in order for the Plan to satisfy the
                                      14
     
     requirements of Section 422(b) of the Code); or

                 (iii)  modify the Plan in any other way if such
     modification requires stockholder approval in order for the Plan to
     satisfy the requirements of Section 422(b) of the Code.

              (b)  The Board may in its sole discretion submit any other
     amendment to the Plan for stockholder approval, including, but not
     limited to, amendments to the Plan intended to satisfy the
     requirements of Section 162(m) of the Code and the regulations
     promulgated thereunder regarding the exclusion of performance-based
     compensation from the limit on corporate deductibility of
     compensation to certain executive officers.

              (c)  It is expressly contemplated that the Board may amend
     the Plan in any respect the Board deems necessary or advisable to
     provide optionees with the maximum benefits provided or to be
     provided under the provisions of the Code and the regulations
     promulgated thereunder relating to employee Incentive Stock Options
     and/or to bring the Plan and/or Options granted under it into
     compliance therewith.

              (d)  Rights and obligations under any Stock Award granted
     before amendment of the Plan shall not be impaired by any amendment
     of the Plan, unless:  (i) the Company requests the consent of the
     person to whom the Stock Award was granted; and (ii) such person
     consents in writing.

         16.  TERMINATION OR SUSPENSION OF THE PLAN.

              (a)  The Board may suspend or terminate the Plan at any
     time.  Unless sooner terminated, the Plan shall terminate on December
     31, 2000.  No Stock Awards may be granted under the Plan while the
     Plan is suspended or after it is terminated.

              (b)  Rights and obligations under any Stock Awards granted
     while the Plan is in effect shall not be impaired by suspension or
     termination of the Plan, except with the consent of the person to
     whom the Stock Award was granted.

         17.  EFFECTIVE DATE OF PLAN.

               The Plan shall become effective as determined by the Board.















                                      15
