                  (1)      To determine from time to time which of the persons
eligible under the Plan shall be granted Options; when and how each Option shall
be granted; whether an Option will be an Incentive Stock Option or a
Nonstatutory Stock Option; the provisions of each Option granted (which need not

                                       3



                  (2)      To construe and interpret the Plan and Options
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 Option Agreement, 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 11.

contrary contained herein, the Board may delegate administration of the Plan to
any person or persons and the term "Committee" shall apply to any person or
persons to whom such authority has been delegated. Notwithstanding anything in

Disinterested Person shall not apply (i) prior to the date of the first
registration of an equity security of the Company under Section 12 of the
Exchange Act, or (ii) if the Board or the Committee expressly declares that such
requirement shall not apply. Any Disinterested Person shall otherwise comply
with the requirements of Rule 16b-3.

adjustments upon changes in stock, the stock that may be sold pursuant to
Options shall not exceed in the aggregate Five Hundred Thousand (500,000) shares
of the Company's common stock. If any Option shall for any reason expire or
otherwise terminate, in whole or in part, without having been exercised in full,
the stock not purchased under such Option 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.
Nonstatutory Stock Options may be granted only to Employees, Directors or
Consultants.

         (b)      A Director shall in no event be eligible for the benefits of
the Plan unless at the time discretion is exercised in the selection of the
Director as a person to whom Options may be granted, or in the determination of
the number of shares which may be covered by Options granted to the Director:
(i) the Board has delegated its discretionary authority over the Plan to a
Committee which consists solely of Disinterested Persons; or (ii) the Plan
otherwise complies with the requirements of Rule 16b-3. The Board shall
otherwise comply with the requirements of Rule 16b-3. This subsection 5(b) shall
not apply (i) prior to the date of the first registration of an equity security
of the Company under Section 12 of the Exchange Act, or (ii) if the Board or
Committee expressly declares that it shall not apply.

         (c)      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 price of such Option is at least
one hundred ten percent (110%) of the Fair Market Value of such stock at the
date of grant and the Option is not exercisable after the expiration of the five
(5) years from the date of grant.

                                       5



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.

         (c)      Consideration. The purchase price of stock acquired pursuant
to an Option shall be paid, to the extent permitted by applicable statues 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 the grant or
exercise 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 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 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. A
Nonstatutory Stock Option shall not be transferable except by will or by the
laws of descent and distribution or pursuant to a qualified domestic relations
order satisfying the requirements of Rule 16b-3 and the rules thereunder (a
"QDRO"), and shall be exercisable during the lifetime of the person to whom the
Option is

                                       6



granted only by such person or any transferee pursuant to a QDRO. 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 vesting provisions of
individual Options may vary but in each case will provide for vesting of at
least twenty percent (20%) per year of the total number of shares subject to the
Option. 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)      Securities Law Compliance. The Company may require any
Optionee, or any person to whom an Option is transferred under subsection 6(d),
as a condition of exercising any such Option, (1) to give written assurances
satisfactory to the Company as to the Optionee'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 Option; and (2) to give written assurances satisfactory to the
Company stating that such person is acquiring the stock subject to the Option
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 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 (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,

                                       7



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.

         (g)      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.

         (h)      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.

         (i)      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

                                       8



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.

         (j)      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 repurchase right in favor of the Company or to any
other restriction the Board determines to be appropriate.

         (k)      Withholding. To the extent provided by the terms of an Option
Agreement, the 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: (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 of the Option; or (3)
delivering to the Company owned and unencumbered shares of the common stock of
the Company.

7.       COVENANTS OF THE COMPANY.

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

         (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 options;
provided, however, that this undertaking shall not require the Company to
register under Securities Act either the Plan, any Option or any stock issued or
issuable pursuant to any such Option. If, after reasonable efforts, the Company
is unable to obtain from any such regulatory commission or agency the authority
which counsel for the

                                       9



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 Options unless and until such authority is
obtained.

8.       USE OF PROCEEDS FROM STOCK.

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

9.       MISCELLANEOUS.

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

         (b)      Neither an Optionee nor any person to whom an Option is
transferred under subsection 6(d) 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 Option
granted pursuant thereto shall confer upon any Employee, Director, Consultant or
Optionee 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 or relationship as a
Director or Consultant of any Employee, Director, Consultant or Optionee with or
without cause.

         (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
granted after 1986 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 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
under the Plan and/or (ii) with the

                                       10



consent of the affected holders of Options, the cancellation of any outstanding
Options 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 eighty-five percent (85%) of the Fair
Market Value (in the case of an Incentive Stock Option one hundred percent
(100%) of the Fair Market Value unless the holder thereof is a ten percent (10%)
stockholder (as defined in subsection 5(c)), in which case not less than one
hundred and ten percent (110%) of the Fair Market Value) per share of Common
Stock on the new grant date.

10.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a)      If any change is made in the stock subject to the Plan, or
subject to any Option (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 otherwise), the Plan and outstanding Options will be
appropriately adjusted in the class(es) and maximum number of shares subject to
the Plan and the class(es) and number of shares and price per share of stock
subject to outstanding Options.

         (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, then to the extent permitted by applicable law: (i) any
surviving corporation shall assume any Options outstanding under the Plan or
shall substitute similar Options for those outstanding under the Plan, or (ii)
such Options shall continue in full force and effect. In the event any surviving
corporation refuses to assume or continue such Options, or to substitute similar
options for those outstanding under the Plan, then, with respect to Options held
by persons then performing services as Employees, Directors or Consultants, the
time during which such Options may be exercised shall be accelerated and the
Options terminated if not exercised prior to such event.

11.      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 10 relating to adjustments upon
changes in 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:

                  (1)      Increase the number of shares reserved for Options
under the Plan;

                  (2)      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 requirements of Section 422 of the
Code); or

                  (3)      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 of the Code or to comply with the requirements of Rule 16b-3.

         (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
