administration.  The Board, in the exercise of this power, may correct any

    4.   SHARES SUBJECT TO THE PLAN.

changes in stock, the stock that may be issued pursuant to Stock Awards shall
not exceed in the aggregate two million two hundred twenty-one thousand eight
hundred eighteen (2,221,818) shares of the Company's common stock.  If any Stock
Award shall for any reason expire or otherwise terminate, in whole or in part,
without having been exercised in full, the stock not acquired under such Stock
Award shall revert to and again become available for issuance under the Plan. 
Shares subject to Stock Appreciation Rights exercised in accordance with Section
8 of the Plan shall not be available for subsequent issuance under the Plan.

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


5.  ELIGIBILITY.

    (a)  Incentive Stock Options and Stock Appreciation Rights appurtenant
thereto may be granted only to Employees.  Stock Awards other than Incentive

                                       5.
<PAGE>

Stock Options and Stock Appreciation Rights appurtenant thereto may be 
granted only to Employees, Directors or Consultants.

    (b)  No person shall be eligible for the grant of an Incentive Stock Option
or an award to purchase restricted stock 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 ten percent (110%)
of the Fair Market Value of such 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, or in the case of a restricted stock purchase award, the purchase
price is at least one hundred percent (100%) of the Fair Market Value of such
stock at the date of grant.

6.  OPTION PROVISIONS.

    Each Option shall be in such form and shall contain such terms and
conditions as the Board 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)  TERM.  No Option shall be exercisable after the expiration of ten (10)
years from the date it was granted.

    (b)  PRICE.  The exercise price of each Incentive Stock Option shall be not
less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted; the exercise price of
each Nonstatutory Stock Option shall be not less than eighty-five percent (85%)
of the Fair Market Value of the stock subject to the Option on the date the
Option is granted.  Notwithstanding the foregoing, an Option (whether an
Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an
exercise price lower than that set forth in the preceding sentence if such
Option is granted pursuant to an assumption or substitution for another option
in a manner satisfying the provisions of Section 424(a) of the Code.

    (c)  CONSIDERATION.  The purchase price of 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, at the time of the grant of the
Option, (A) by delivery to the Company of other common stock of the Company,
(B) according to a deferred payment or other arrangement (which may include,
without limiting the generality of the foregoing, the use of other common stock
of the Company) with the person to whom the Option is granted or to whom the
Option is transferred pursuant to subsection 6(d), or (C) in any other form of
legal consideration that may be acceptable to the Board.

    In the case of any deferred payment arrangement, interest shall be payable
at least annually and shall be charged at the minimum rate of interest necessary

                                       6.
<PAGE>

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)  TRANSFERABILITY.  An Incentive Stock Option shall not be transferable
except by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of the person to whom the Incentive Stock Option
is granted only by such person.  A Nonstatutory Stock Option may be transferred
to the extent provided in the Option Agreement; provided that if the Option
Agreement of a Nonstatutory Stock Option does not expressly permit such
transfer, such Nonstatutory Stock Option shall not be transferable except by
will, by the laws of descent and distribution or pursuant to a domestic
relations order satisfying the requirements of Rule 16a-12 of the Exchange Act
and shall be exercisable during the lifetime of the person to whom such
Nonstatutory Stock Option is granted only by such person or any transferee
pursuant to a domestic relations order.  Notwithstanding the foregoing, the
person to whom the Option is granted may, by delivering written notice to the
Company, in a form satisfactory to the Company, designate a third party who, in
the event of the death of the Optionee, shall thereafter be entitled to exercise
the Option.

    (e)  VESTING.  The total number of shares of stock subject to an Option
may, but need not, be allotted in periodic installments (which may, but need
not, be equal).  The Option Agreement may provide that 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 became vested but was not fully
exercised.  The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate.  The provisions of this
subsection 6(e) are subject to any Option provisions governing the minimum
number of shares as to which an Option may be exercised.

    (f)  TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR CONSULTANT. 
In the event an Optionee's Continuous Status as an Employee, Director or
Consultant terminates (other than upon the Optionee's death or disability), the
Optionee may exercise his or her Option (to the extent that the Optionee was
entitled to exercise it at the date of termination) but only within such period
of time ending on the earlier of (i) the date three (3) months after the
termination of the Optionee's Continuous Status as an Employee, Director or
Consultant (or such longer or shorter period specified in the Option Agreement),
or (ii) the expiration of the term of the Option as set forth in the Option
Agreement.  If, after termination, the Optionee does not exercise his or her
Option within the time specified in the Option Agreement, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.

    An Optionee's Option Agreement may also provide that if the exercise of 
the Option following the termination of the Optionee's Continuous Status as 
an Employee, Director, or Consultant (other than upon the Optionee's death or 
disability) would result in liability under Section 16(b) of the Exchange 
Act, then the Option shall terminate on the earlier of (i) the expiration of 
the term of the Option set forth in the Option Agreement, or (ii) the tenth 

                                       7.
<PAGE>

(10th) day after the last date on which such exercise would result in such 
liability under Section 16(b) of the Exchange Act.  Finally, an Optionee's 
Option Agreement may also provide that if the exercise of the Option 
following the termination of the Optionee's Continuous Status as an Employee, 
Director or Consultant (other than upon the Optionee's death or disability) 
would be prohibited at any time solely because the issuance of shares would 
violate the registration requirements under the Act, then the Option shall 
terminate on the earlier of (i) the expiration of the term of the Option set 
forth in the first paragraph of this subsection 6(f), or (ii) the expiration 
of a period of three (3) months after the termination of the Optionee's 
Continuous Status as an Employee, Director or Consultant during which the 
exercise of the Option would not be in violation of such registration 
requirements.

    (g)  DISABILITY OF OPTIONEE.  In the event an Optionee's Continuous Status
as an Employee, Director or Consultant terminates as a result of the Optionee's
disability, the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it at the date of termination), but only
within such period of time ending on the earlier of (i) the date twelve (12)
months following such termination (or such longer or shorter period specified in
the Option Agreement), or (ii) the expiration of the term of the Option as set
forth in the Option Agreement.  If, at the date of termination, the Optionee is
not entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan.  If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.

    (h) DEATH OF OPTIONEE.  In the event of the death of an Optionee during, or
within a period specified in the Option after the termination of, the Optionee's
Continuous Status as an Employee, Director or Consultant, the Option may be
exercised (to the extent the Optionee was entitled to exercise the Option at the
date of death) by the Optionee's estate, by a person who acquired the right to
exercise the Option by bequest or inheritance or by a person designated to
exercise the option upon the Optionee's death pursuant to subsection 6(d), but
only within the period ending on the earlier of (i) the date eighteen (18)
months following the date of death (or such longer or shorter period specified
in the Option Agreement), or (ii) the expiration of the term of such Option as
set forth in the Option Agreement.  If, at the time of death, the Optionee was
not entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan.  If, after death, the Option is not exercised
within the time specified herein, the Option shall terminate, and the shares
covered by such Option shall revert to and again become available for issuance
under the Plan.

    (i)  EARLY EXERCISE.  The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option.  Any unvested shares so
purchased shall be subject to a repurchase right in favor of the Company or to
any other restriction the Board determines to be appropriate.

                                       8.
<PAGE>

    (j)  RE-LOAD OPTIONS.  Without in any way limiting the authority of the 
Board or Committee to make or not to make grants of Options hereunder, 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. Notwithstanding the foregoing, a Re-Load 
Option which is granted to a 10% stockholder (as described in subsection 
5(c)), shall have an exercise price which is equal to one hundred ten percent 
(110%) of the Fair Market Value of the stock subject to the Re-Load Option on 
the date of exercise of the original Option and shall have a term which is no 
longer than five (5) years.

    Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
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
dollar ($100,000) annual limitation on exercisability of Incentive Stock Options
described in subsection 12(e) of the Plan and in Section 422(d) of the Code. 
There shall be no Re-Load Options on a Re-Load Option.  Any such Re-Load Option
shall be subject to the availability of sufficient shares under subsection 4(a)
and shall be subject to such other terms and conditions as the Board or
Committee may determine which are not inconsistent with the express provisions
of the Plan regarding the terms of Options.


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

    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)  PURCHASE PRICE.  The purchase price under each restricted stock
purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such agreement, but in no event shall the purchase
price be less than eighty-five percent (85%) of the stock's Fair Market Value on
the date such award is made.  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.

                                       9.
<PAGE>

    (b)  TRANSFERABILITY.  No rights under a stock bonus or restricted stock
purchase agreement shall be transferable except by will or the laws of descent
and distribution or pursuant to a domestic relations order satisfying the
requirements of Rule 16a-12 of the Exchange Act and any administrative
interpretations or pronouncements thereunder, so long as stock awarded under
such agreement remains subject to the terms of the agreement.  

    (c)  CONSIDERATION.  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 stock is sold;
or (iii) in any other form of legal consideration that may be acceptable to the
Board or the Committee in its discretion.  Notwithstanding the foregoing, the
Board or the Committee to which administration of the Plan has been delegated
may award stock pursuant to a stock bonus agreement in consideration for past
services actually rendered to the Company or for its benefit.

    (d)  VESTING.  Shares of 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)  TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR CONSULTANT. 
In the event a Participant's Continuous Status as an Employee, Director or
Consultant terminates, the Company may repurchase or otherwise reacquire,
subject to the limitations described in subsection 7(d), any or all of the
shares of 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.  STOCK APPRECIATION RIGHTS.

    (a)  The Board or Committee shall have full power and authority,
exercisable in its sole discretion, to grant Stock Appreciation Rights under the
Plan to Employees or Directors of or Consultants to, the Company or its
Affiliates.  To exercise any outstanding Stock Appreciation Right, the holder
must provide written notice of exercise to the Company in compliance with the
provisions of the Stock Award Agreement evidencing such right.  If a Stock
Appreciation Right is granted to an individual who is at the time subject to
Section 16(b) of the Exchange Act (a "Section 16(b) Insider"), the Stock Award
Agreement of grant shall incorporate all the terms and conditions at the time
necessary to assure that the subsequent exercise of such right shall qualify for
the safe-harbor exemption from short-swing profit liability provided by Rule
16b-3 promulgated under the Exchange Act (or any successor rule or regulation). 
No limitation shall exist on the aggregate amount of cash payments the Company
may make under the Plan in connection with the exercise of a Stock Appreciation
Rights.

    (b)  Three types of Stock Appreciation Rights shall be authorized for
issuance under the Plan:

                                       10.
<PAGE>

         (1)  TANDEM STOCK APPRECIATION RIGHTS.  Tandem Stock Appreciation
Rights will be granted appurtenant to an Option, and shall, except as
specifically set forth in this Section 8, be subject to the same terms and
conditions applicable to the particular Option grant to which it pertains. 
Tandem Stock Appreciation Rights will require the holder to elect between the
exercise of the underlying Option for shares of stock and the surrender, in
whole or in part, of such Option for an appreciation distribution.  The
appreciation distribution payable on the exercised Tandem Right shall be in cash
(or, if so provided, in an equivalent number of shares of stock based on Fair
Market Value on the date of the Option surrender) in an amount up to the excess
of (A) the Fair Market Value (on the date of the Option surrender) of the number
of shares of stock covered by that portion of the surrendered Option in which
the Optionee is vested over (B) the aggregate exercise price payable for such
vested shares.

         (2)  CONCURRENT STOCK APPRECIATION RIGHTS.  Concurrent Rights will be
granted appurtenant to an Option and may apply to all or any portion of the
shares of stock subject to the underlying Option and shall, except as
specifically set forth in this Section 8, be subject to the same terms and
conditions applicable to the particular Option grant to which it pertains.  A
Concurrent Right shall be exercised automatically at the same time the
underlying Option is exercised with respect to the particular shares of stock to
which the Concurrent Right pertains.  The appreciation distribution payable on
an exercised Concurrent Right shall be in cash (or, if so provided, in an
equivalent number of shares of stock based on Fair Market Value on the date of
the exercise of the Concurrent Right) in an amount equal to such portion as
shall be determined by the Board or the Committee at the time of the grant of
the excess of (A) the aggregate Fair Market Value (on the date of the exercise
of the Concurrent Right) of the vested shares of stock purchased under the
underlying Option which have Concurrent Rights appurtenant to them over (B) the
aggregate exercise price paid for such shares.

         (3)  INDEPENDENT STOCK APPRECIATION RIGHTS.  Independent Rights will
be granted independently of any Option and shall, except as specifically set
forth in this Section 8, be subject to the same terms and conditions applicable
to Nonstatutory Stock Options as set forth in Section 6.  They shall be
denominated in share equivalents.  The appreciation distribution payable on the
exercised Independent Right shall be not greater than an amount equal to the
excess of (A) the aggregate Fair Market Value (on the date of the exercise of
the Independent Right) of a number of shares of Company stock equal to the
number of share equivalents in which the holder is vested under such Independent
Right, and with respect to which the holder is exercising the Independent Right
on such date, over (B) the aggregate Fair Market Value (on the date of the grant
of the Independent Right) of such number of shares of Company stock.  The
appreciation distribution payable on the exercised Independent Right shall be in
cash or, if so provided, in an equivalent number of shares of stock based on
Fair Market Value on the date of the exercise of the Independent Right.

9.  CANCELLATION AND RE-GRANT OF OPTIONS.

    The Board or the Committee shall have the authority to effect, at any time
and from time to time,  (i) the repricing of any outstanding Options and/or any
Stock Appreciation Rights under the Plan and/or (ii) with the consent of the

                                       11.
<PAGE>

affected holders of Options and/or Stock Appreciation Rights, the 
cancellation of any outstanding Options and/or any Stock Appreciation Rights 
under the Plan and the grant in substitution therefor of new Options and/or 
Stock Appreciation Rights under the Plan covering the same or different 
numbers of shares of stock, but having an exercise price per share not less 
than eighty-five percent (85%) of the Fair Market Value (one hundred percent 
(100%) of the Fair Market Value in the case of an Incentive Stock Option) or, 
in the case of an Incentive Stock Option granted to a 10% stockholder (as 
described in subsection 5(c)), not less than one hundred ten percent (110%) 
of the Fair Market Value) per share of stock on the new grant date.  
Notwithstanding the foregoing, the Board or the Committee may grant an Option 
and/or Stock Appreciation Right with an exercise price lower than that set 
forth above if such Option and/or Stock Appreciation Right is granted as part 
of a transaction to which section 424(a) of the Code applies.  

10. COVENANTS OF THE COMPANY.

    (a)  During the terms of the Stock Awards, the Company shall keep available
at all times the number of shares of stock required to satisfy such Stock
Awards.

    (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 stock upon exercise of the Stock Award; provided,
however, that this undertaking shall not require the Company to register under
the Securities Act of 1933, as amended (the "Securities Act") either the Plan,
any Stock Award or any 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 which counsel for the Company
deems necessary for the lawful issuance and sale of stock under the Plan, the
Company shall be relieved from any liability for failure to issue and sell stock
upon exercise of such Stock Awards unless and until such authority is obtained.

11. USE OF PROCEEDS FROM STOCK.

    Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.

12. MISCELLANEOUS.

    (a)  The Board shall have the power to accelerate the time at which a Stock
Award may first be exercised or the time during which a Stock Award or any part
thereof will vest pursuant to subsection 6(e), 7(d) or 8(b), notwithstanding the
provisions in the Stock Award stating the time at which it may first be
exercised or the time during which it will vest.

    (b)  Neither an Employee, Director or Consultant nor any person to whom a
Stock Award is transferred under subsection 6(d), 7(b), or 8(b) 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 Stock Award unless and until such person has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.

                                       12.
<PAGE>

    (c)  Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any Employee, Director, Consultant or other
holder of Stock Awards any right to continue in the employ of the Company or any
Affiliate (or to continue acting as a Director or Consultant) or shall affect
the right of the Company or any Affiliate to terminate the employment of any
Employee with or without cause the right of the Company's Board of Directors
and/or the Company's stockholders to remove any Director pursuant to the terms
of the Company's By-Laws and the provisions of the Delaware General Corporation
Law, or the right to terminate the relationship of any Consultant pursuant to
the terms of such Consultant's agreement with the Company or Affiliate.

    (d)  To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

    (e)  The Company may require any person to whom a Stock Award is granted,
or any person to whom a Stock Award is transferred pursuant to subsection 6(d),
7(b) or 8(b), as a condition of exercising or acquiring stock under any Stock
Award, (1) 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 reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters, and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (2) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Stock Award for such person's own account and
not with any present intention of selling or otherwise distributing the stock. 
The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered under
a then currently effective registration statement under 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.  The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

    (f)  To the extent provided by the terms of a Stock Award Agreement, the
person to whom a Stock Award is granted may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of stock
under a Stock Award by any of the following means or by a combination of such
means:  (1) tendering a cash payment; (2) authorizing the Company to withhold
shares from the shares of the common stock otherwise issuable to the participant
as a result of the exercise or acquisition of stock under the Stock Award; or
(3) delivering to the Company owned and unencumbered shares of the common stock
of the Company.

                                       13.

13. ADJUSTMENTS UPON CHANGES IN STOCK.

    (a)  If any change is made in the stock subject to the Plan, or subject to
any Stock Award, without the receipt of consideration by the Company (through
merger, consolidation, reorganization, recapitalization, reincorporation, 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 will be appropriately adjusted in the class(es) and maximum
number of shares subject to the Plan pursuant to subsection 4(a), and the
outstanding Stock Awards will be appropriately adjusted in the class(es) and
number of shares and price per share of stock subject to such outstanding Stock
Awards.  Such adjustments 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 by the Company".)

    (B)  In the event of:  (1) a merger or consolidation in which the Company
is not the surviving corporation or (2) a reverse merger in which the Company is
the surviving corporation but the shares of the Company's common stock
outstanding immediately preceding the merger are converted by virtue of the
merger into other property, whether in the form of securities, cash or otherwise
then to the extent permitted by applicable law:  (i) any surviving corporation
or an Affiliate of such surviving corporation shall assume any Stock Awards
outstanding under the Plan or shall substitute similar Stock Awards for those
outstanding under the Plan, or (ii) such Stock Awards shall continue in full
force and effect.  In the event any surviving corporation and its Affiliates
refuse to assume or continue such Stock Awards, or to substitute similar Stock
Awards for those outstanding under the Plan, then such Stock Awards shall be
terminated if not exercised prior to such event.  In the event of a dissolution
or liquidation of the Company, any Stock Awards outstanding under the Plan shall
terminate if not exercised prior to such event.

14. AMENDMENT OF THE PLAN AND STOCK AWARDS.

    (a)  The Board at any time, and from time to time, may amend the Plan. 
However, except as provided in Section 13 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the stockholders of
the Company to the extent stockholder approval is necessary for the Plan to
satisfy the requirements of Section 422 of the Code, Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

    (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 paid 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 eligible Employees,
Directors or Consultants with the maximum benefits provided or to be provided

                                       14.
<PAGE>

under the provisions of the Code and the regulations promulgated thereunder 
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive 
Stock 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.

    (e)  The Board at any time, and from time to time, may amend the terms of
any one or more Stock Award; provided, however, that the rights and obligations
under any Stock Award shall not be impaired by any such amendment unless (i) the
Company requests the consent of the person to whom the Stock Award was granted
and (ii) such person consents in writing.

15. 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 May 1, 2001, which shall be
within ten (10) years from the date the Plan is adopted by the Board or approved
by the stockholders of the Company, whichever is earlier.  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 Award 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.

16. EFFECTIVE DATE OF PLAN.

    The Plan as amended on December 20, 1996, shall become effective on such
date, but no Stock Awards granted under the Plan, as amended, shall be exercised
unless and until the Plan, as amended, has been approved by the stockholders of
the Company, which approval shall be within twelve (12) months before or after
the date the Plan, as amended, is adopted by the Board.

                                       15.
