to a Committee, the Committee shall have, in connection with the administration
of the Plan, the powers theretofore possessed by the Board, including the power
to delegate to a subcommittee of two (2) or more Outside Directors any of the
administrative powers the Committee is authorized to exercise (and references in
this Plan to the Board shall thereafter be to the Committee or such a
subcommittee), subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan. Notwithstanding anything in this Section 3 to the

(2,350,000) 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.

          (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 may be granted only to Employees. Stock
Awards other than Incentive Stock Options may be granted only to Employees,
Directors or Consultants.

          (B) No person shall be eligible for the grant of an Incentive Stock
Option 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 



                                       5
   6
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.

          (C) Subject to the provisions of Section 13 relating to adjustments
upon changes in stock, no person shall be eligible to be granted Options
covering more than five hundred thousand (500,000) shares of the Company's
common stock in any calendar year.

     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, and the exercise price
of a 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, including,
at the discretion of the Board or Committee, pursuant to a cashless exercise of
Options as described in Regulation T promulgated by the Federal Reserve Board,
subject to applicable securities law restrictions or (ii) at the discretion of
the Board or the Committee exercised at the time of grant of the Option, (A) by
delivery to the Company of other common stock of the Company having a Fair
Market Value at the time of exercise equal to the option exercise price
(provided that such shares have been held for a period of at least six (6)
months), (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 Optionee, or (C) in any other form of
legal consideration that may be acceptable to the Board.



                                       6
   7
In the case of any deferred payment arrangement, (i) interest shall be payable
at least annually and shall be charged at 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, and (ii) the "par value" of the common stock (as defined in
the Delaware General Corporation Law) shall be paid by the Participant in cash.

          (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 does not expressly permit the transfer of a Nonstatutory Stock
Option, the Nonstatutory 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 Option is granted only by such person.
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
the earlier of (i) such period of time as is determined by the Board 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, 



                                       7
   8
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 (10th) day
after the last date on which such exercise would result in such liability under
Section 16(b) of the Exchange Act.

          (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 the earlier of (i) such period of time as is
determined by the Board 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 earlier of (i) such period of time as is determined by the
Board or (ii) the expiration of the term of the 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 may be subject to a 



                                       8
   9
repurchase right in favor of the Company or to any other restriction the Board
determines to be appropriate.

          (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 the
Company's 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 an Incentive Stock
Option and which is granted to a 10% stockholder (as described in subsection
5(b)), 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(d) 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:



                                       9
   10
          (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 for its benefit.

          (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, if provided by the terms of the Stock Award Agreement,
pursuant to a domestic relations order within the meaning of Rule 16a-12 under
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,
except that payment of the common stock's "par value" (as defined in the
Delaware General Corporation Law) shall not be made by deferred payment or other
arrangement; 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 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.   OPTION GRANTS TO NON-EMPLOYEE DIRECTORS.

          (A) Each individual who, on the Stockholder Approval Date, is a
Director and is not an Employee of the Company (a "Non-Insider Director") shall
automatically be granted, on the Stockholder Approval Date, a Nonstatutory
Option to 



                                       10
   11
purchase ten thousand (10,000) shares of the Company's common stock (a "1997
Director Option"). Each individual who first becomes a Non-Insider Director of
the Company (and was not already a Director) after the Stockholder Approval Date
shall automatically be granted, upon his or her election or appointment as a
Non-Insider Director, a Nonstatutory Option to purchase thirty thousand (30,000)
shares of the Company's common stock (an "Initial Option"). In addition, at the
time of each of the Company's annual meetings of stockholders, beginning with
the Company's 1998 annual meeting, each Non-Insider Director who has been a
Director for at least six (6) months as of the date of such meeting shall
automatically be granted a Nonstatutory Option to purchase ten thousand (10,000)
shares of the Company's common stock (an "Annual Option"). The number of shares
of common stock to be covered by Options granted pursuant to this Section 8
shall be subject to adjustment pursuant to Section 13 hereof.

          (B) The date of grant for each 1997 Director Option shall be the
Stockholder Approval Date. The date of grant for each Initial Option shall be
the date of the Non-Insider Director's election or appointment to the Board.
The date of grant for each Annual Option shall be the first business day
following the date of the Company's 1998 annual meeting of stockholders and each
annual meeting of stockholders thereafter, as long as such Non-Insider Director
is then serving as a Non-Insider Director of the Company.

          (C) The exercise price of Options granted pursuant to this Section 8
shall be the Fair Market Value of the Company's common stock on the date of
grant.

          (D) Each Option granted to a Non-Insider Director pursuant to this
Section 8 shall expire upon the earlier of (i) ten (10) years from the date of
grant, (ii) three (3) months after termination of the Non-Insider Director's
Continuous Status as an Employee, Director or Consultant (other than upon the
Non-Insider Director's death or disability), or (iii) one (1) year after
termination of the Non-Insider Director's Continuous Status as an Employee,
Director or Consultant as a result of death or disability.

          (E) Each Initial Option granted pursuant to this Section 8 shall vest
monthly as to one-forty-eighth (1/48th) of the shares subject to such Option
after the date of grant of the Option, until fully vested, provided that the
Optionee's Continuous Status as an Employee, Director or Consultant has not
terminated prior to such monthly vesting date. Upon the vesting of each
installment portion of the Option as provided herein, the Option may be
exercised with respect to the shares represented by that installment. Each 1997
Director Option and each Annual Option shall vest monthly as to one-twelfth
(1/12th) of the shares subject to such Option after the date of grant of the
Option, until fully vested, provided that the Optionee's Continuous Status as an
Employee, Director or Consultant has not terminated prior to such monthly
vesting date. No portion of an 



                                       11
   12
Option granted under this Section 8 may be exercised prior to the vesting date
applicable to such Option or portion thereof, as the case may be.

          (F) Payment of the exercise price per share of each Option granted
under this Section 8 shall be made (i) in cash (including check) at the time of
exercise, (ii) pursuant to a cashless exercise program that is in compliance
with regulations promulgated by the Federal Reserve Board and which, prior to
the issuance of the shares being purchased, results in either the receipt by the
Company of cash (or check) or irrevocable instructions to a qualified broker
that sufficient shares be sold immediately in order to deliver the aggregate
exercise price to the Company from the sales proceeds, or (iii) by a combination
of the methods specified in (i) and (ii).

          (G) No Options granted pursuant to this Section 8 may be exercised
prior to shareholder approval of the amendment of the Plan adding this Section
8.

     9.   CANCELLATION AND RE-GRANT OF OPTIONS.

          (A) 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,
(ii) with the consent of any adversely affected holders of Options, 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 stock, but having an exercise price per share not
less than: eighty-five percent (85%) of the Fair Market Value for a Nonstatutory
Stock Option, 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 held by a
10% stockholder (as described in subsection 5(b)), 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 with an exercise price lower than that set forth above if such Option is
granted as part of a transaction to which Section 424(a) of the Code applies.

          (B) Shares subject to an Option canceled under this Section 9 shall
continue to be counted against the maximum number of shares subject to Options
permitted to be granted pursuant to subsection 5(c) of the Plan. The repricing
of an Option under this Section 9, resulting in a reduction of the exercise
price, shall be deemed to be a cancellation of the original Option and the grant
of a substitute Option; in the event of such repricing, both the original and
the substituted Options shall be counted against the maximum number of shares
subject to Options permitted to be granted pursuant to subsection 5(c) of the
Plan. The provisions of this subsection 9(b) shall be applicable only to the
extent required by Section 162(m) of the Code.

     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) or 7(d), 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, a Director, a Consultant nor any person to
whom a Stock Award is transferred pursuant to subsection 6(d) or 7(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.

          (C) Nothing in the Plan or any instrument executed or Stock Award
granted pursuant thereto shall confer upon any Employee, Director or 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 notice and with or without cause, or
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 



                                       13
   14

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 in accordance with
the Plan, 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 having a Fair Market Value at the time of such
withholding equal to the amount of the withholding obligation (provided that
such shares have been held for a period of at least six (6) months).

     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 maximum
number of shares subject to award to any person during any calendar year
pursuant to subsection 5(c), 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 dissolution, liquidation or sale of
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving corporation; or (3) 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; or (4) the acquisition by any person, entity or group within
the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act, or any
comparable successor provisions (excluding any employee benefit plan, or related
trust, sponsored or maintained by the Company or any Affiliate of the Company)
of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under
the Exchange Act, or comparable successor rule) of securities of the Company
representing at least fifty percent (50%) of the combined voting power entitled
to vote in the election of directors, then (a) with respect to Stock Awards held
by persons then performing services as Employees, Directors or Consultants, the
vesting and, if applicable, exercisability of such Stock Awards shall be
accelerated prior to such event and any Stock Awards requiring exercise shall be
terminated if not exercised after such acceleration and at or prior to such
event, and (b) with respect to any other Stock Awards outstanding under the
Plan, such Stock Awards shall be terminated 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 



                                       15
   16
the extent stockholder approval is necessary for the Plan, as modified by the
amendment, to satisfy the requirements of Section 422 of the Code or Rule 16b-3
under the Exchange Act.

          (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 Optionees with the
maximum benefits provided or to be provided 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 July 15, 2007. 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; TERM OF PLAN.

          The Plan, as amended and restated by the Board on the Amendment Date
shall be effective on the Amendment Date, provided that no Stock Awards granted
under the Plan that were not provided for under the Plan prior to the Amendment
Date shall be 



                                       16
   17
exercised unless and until the Plan, as amended, has been approved by the
stockholders of the Company within twelve (12) months before or after the
Amendment Date.
