I.   Purposes Of The Plan.

     (a)  This Stock Option Plan (the "Plan") is intended to promote the
interests of Terrapin Technologies, Inc., a Delaware corporation (the "Company")
by providing a method whereby (i) employees (including officers and directors)
of the Company (or its parent or subsidiary corporations) responsible for the
management, growth and financial success of the Company (or its parent or
subsidiary corporations), (ii) the non-employee members of the Company's Board
of Directors (or any parent or subsidiary corporations) and (iii) consultants
and independent contractors who provide valuable services to the Company (or its
parent or subsidiary corporations) may be offered incentives and rewards which
will encourage them to acquire a proprietary interest, or otherwise increase
their proprietary interest, in the Company and continue to render services to
the Company (or its parent or subsidiary corporations).

     (b)  For purposes of the Plan, the following provisions shall be applicable
in determining the parent and subsidiary corporations of the Company:

          (i)    Any corporation (other than the Company) in an unbroken chain
of corporations ending with the Company shall be considered to be a parent
corporation of the Company, provided each such corporation in the unbroken chain
(other than the Company) owns, at the time of the determination, stock
possessing fifty percent (50%) or more of the total combined voting power of all
classes of stock in one of the other corporations in such chain.

          (ii)   Each corporation (other than the Company) in an unbroken chain
of corporations beginning with the Company shall be considered to be a
subsidiary of the Company, provided each such corporation (other than the last
corporation) in the unbroken chain owns, at the time of the determination, stock
possessing fifty percent (50%) or more of the total combined voting power of all
classes of stock in one of the other corporations in such chain.

II.  Administration Of The Plan.

     (a)  The Plan shall be administered by the Board of Directors (the "Board")
of the Company. The Board, however, may at any time appoint a committee
("Committee") of three

                                       1.
<PAGE>

(3) or more members of the Board and delegate to such Committee one or more of
the administrative powers allocated to the Board under the provisions of the
Plan, including (without limitation) the power to grant options under the Plan
and administer the option surrender and option acceleration provisions of the
Plan. Members of the Committee shall serve for such period of time as the Board
may determine and shall be subject to removal by the Board at any time. The
Board may also at any time terminate the functions of the Committee and reassume
all powers and authority previously delegated to the Committee.

     (b)  The Plan Administrator (either the Board or the Committee, to the
extent the Committee is at the time responsible for the administration of the
Plans shall have full power and authority (subject to the provisions of the
Plan) to establish such rules and regulations as it may deem appropriate for the
proper administration of the Plan and to make such determinations under, and
issue such interpretations of, the Plan and any outstanding option as it may
deem necessary or advisable. Decisions of the Plan Administrator shall be final
and binding on all parties who have an interest in the Plan or any outstanding
option.

III.  Eligibility For Option Grants.

      (a)  The persons eligible to receive option grants under the Plan are as
follows:

           (i)   employees (including officers and directors) of the Company (or
its parent or subsidiary corporations) who render services which contribute to
the success and growth of the Company (or its parent or subsidiary corporations)
or which may reasonably be anticipated to contribute to the future success and
growth of the Company (or its parent or subsidiary corporations);

          (ii)   the non-employee members of the Board or the nonemployee
members of the Board of Directors of any parent or subsidiary corporations; and

          (iii)  those consultants or independent contractors who provide
valuable services to the Company (or its parent or subsidiary corporations).

     (b)  The Plan Administrator shall have full authority to determine which
eligible individuals are to receive option grants under the Plan, the number of
shares to be covered by each such grant, whether the granted option is to be an
incentive stock option ("Incentive Option") which satisfies the requirements of
Section 422 of the Internal Revenue Code or a non-statutory option not intended
to meet such requirements, the time or times at which each such option is to
become exercisable, and the maximum term for which the option is to be
outstanding.

IV.  Stock Subject To The Plan.

     (a)  The stock issuable under the Plan shall be shares of the Company's
authorized but unissued or reacquired Common Stock. The aggregate number of
shares which may be issued over the term of the Plan shall not exceed 4,950,000
shares. The total number of shares issuable under the Plan shall be subject to
adjustment from time to time in accordance with Section IV(c) of the Plan.

                                       2.
<PAGE>

     (b)  Should an option be terminated for any reason prior to exercise or
surrender in full (including options cancelled in accordance with the
cancellation-regrant provisions of Section VIII of the Plan), the shares subject
to the portion of the option not so exercised or surrendered shall be available
for subsequent option grants under the Plan. Shares subject to any option or
portion thereof surrendered in accordance with Section IX of the Plan and shares
repurchased by the Company pursuant to its repurchase rights under the Plan
shall not be available for subsequent option grants under the Plan.

     (c)  In the event any change is made to the Common Stock issuable under the
Plan by reason of any stock split, stock dividend, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without receipt of consideration, then appropriate adjustments will be
made to (i) the aggregate number of shares and classes of shares issuable under
the Plan and (ii) the number of shares and price per share of the Common Stock
subject to each outstanding option in order to prevent the dilution or
enlargement of benefits thereunder.

V.   Terms And Conditions Of Options.

     Options granted pursuant to the Plan shall be authorized by action of the
Plan Administrator and may, at the Plan Administrator's discretion, be either
Incentive Options or non-statutory options. Individuals who are not employees of
the Company or its parent or subsidiary corporations may only be granted
nonstatutory options. Each granted option shall be evidenced by one or more
instruments in the form approved by the Plan Administrator; provided, however,
that each such instrument shall comply with and incorporate the terms and
conditions specified below. Each instrument evidencing an Incentive Option
shall, in addition, be subject to the applicable provisions of Section VI.

     1.   Option Price.

          A.   The option price per share shall be fixed by the Plan
Administrator, but, subject to the provisions of Section V.1.B below, in no
event shall the option price per share be less than eighty-five percent (85%) of
the fair market value of a share of Common Stock on the date of the option
grant.

          B.   If any individual to whom an option is to be granted pursuant to
the provisions of the Plan is on the date of grant the owner of stock (as
determined under Section 424(d) of the Internal Revenue Code) possessing 10% or
more of the total combined voting power of all classes of stock of the Company
or any one of its parent or subsidiary corporations (such person to be herein
referred to as a 10% Shareholder), then the option price per share shall not be
less than one hundred and ten percent (110%) of the fair market value of one
share of Common Stock on the date of grant.

          C.   The option price shall become immediately due upon exercise of
the option and shall, subject to the provisions of Section X and the instrument
evidencing the grant, be payable in one of the alternative forms specified
below:

               (i) full payment in cash or cash equivalents; or

                                       3.
<PAGE>

               (ii)  full payment in shares of Common Stock held by the optionee
for the requisite period necessary to avoid a charge to the Company's reported
earnings and valued at fair market value on the Exercise Date (as such term is
defined below) in an amount equal to the option price; or

               (iii) a combination of shares of Common Stock held by the
optionee for the requisite period necessary to avoid a charge to the Company's
reported earnings and valued at fair market value on the Exercise Date and cash
or cash equivalents, equal in the aggregate to the option price.

     For purposes of this subparagraph C, the Exercise Date shall be the first
date on which the Company shall have received both written notice of the
exercise of the option and payment of the option price for the purchased shares.

          D.   The fair market value of a share of Common Stock on any relevant
date under subparagraph A, 8 or C above (and for all other valuation purposes
under the Plan) shall be determined in accordance with the following provisions:

               (i)   If the Common Stock is not at the time listed or admitted
to trading on any stock exchange but is traded in the over-the-counter market,
the fair market value shall be the mean between the highest bid and lowest asked
prices (or, if such information is available, the closing selling price) of one
share of Common Stock on the date in question in the over-the-counter market, as
such prices are reported by the National Association of Securities Dealers
through its NASDAQ system or any successor system. If there are no reported bid
and asked prices (or closing selling price) for the Common Stock on the date in
question, then the mean between the highest bid price and lowest asked price (or
the closing selling price) on the last preceding date for which such quotations
exist shall be determinative of fair market value.

               (ii)  If the Common Stock is at the time listed or admitted to
trading on any stock exchange, then the fair market value shall be the closing
selling price of one share of Common Stock on the date in question on the stock
exchange determined by the Plan Administrator to be the primary market for the
Common Stock, as such price is officially quoted in the composite tape of
transactions on such exchange. If there is no reported sale of Common Stock on
such exchange on the date in question, then the fair market value shall be the
closing selling price on the exchange on the last preceding date for which such
quotation exists.

               (iii) If the Common Stock at the time is neither listed nor
admitted to trading on any stock exchange nor traded in the over-the-counter
market, then the fair market value shall be determined by the Plan Administrator
after taking into account such factors as the Plan Administrator shall deem
appropriate, which may include one or more independent professional appraisals.

     2.   Term and Exercise of Options. Each option granted under the Plan shall
be exercisable at such time or times, during such period, and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
instrument evidencing such option; provided, however, that no such option shall
have a term in excess of ten (10) years from the grant date and provided,
further, however, that no such option granted to a 10% Shareholder

                                       4.
<PAGE>

shall have a term in excess of five (5) years from the grant date. During the
lifetime of the optionee, the option shall be exercisable only by the optionee
and shall not be assignable or transferable by the optionee otherwise than by
will or by the laws of descent and distribution.

     3.   Effect of Termination of Employment.

          A.   Should an optionee cease to be an Employee of the Company for any
reason (including death or permanent disability as defined in Section 22(e)(3)
of the Internal Revenue Code) while the holder of one or more outstanding non-
statutory options granted to such optionee under the Plan, then such option or
options shall not (except to the extent otherwise provided pursuant to Section
XI below) remain exercisable for more than a twelve (12) month period (or such
shorter period determined by the Plan Administrator and specified in the
instrument evidencing the grant) following the date of such cessation of
Employee status; provided, however, that under no circumstances shall such
options be exercisable after the specified expiration date of the option term.
Each such option shall, during such twelve (12) month or shorter period, be
exercisable only to the extent of the number of shares (if any) for which the
option is exercisable on the date of such cessation of Employee status. Upon the
expiration of such twelve (12) month or shorter period or (if earlier) upon the
expiration of the option term, the option shall terminate and cease to be
exercisable.

          B.   An Incentive Option shall terminate three (3) months after
termination of the optionee's Employee status with the Company, unless (i) such
termination is due to such person's death or 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 by the optionee (or 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) at any time within twelve (12)
months following such termination of Employee status; or (ii) the option by its
terms specifies that it shall terminate sooner than three (3) months after
termination of the optionee's Employee status. This subparagraph 3(B) 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 Employee status.

          C.   Any option granted to an optionee under the Plan and exercisable
in whole or in part on the date of the optionee's death may be subsequently
exercised, but only to the extent of the number of shares (if any) for which the
option is exercisable on the date of the optionee's death, by the personal
representative of the optionee's estate or by the person or persons to whom the
option is transferred pursuant to the optionee's will or in accordance with the
laws of descent and distribution, provided, and only if such exercise occurs
prior to the earlier of (i) the first anniversary of the date of the optionee's
death or (ii) the specified expiration date of the option term. Upon the
occurrence of the earlier event, the option shall terminate and cease to be
exercisable.

          D.   If (i) the optionee's status as an Employee is terminated for
misconduct (including, but not limited to, any act of dishonesty, willful
misconduct, fraud or embezzlement or any unauthorized disclosure or use of
confidential information or trade secrets) or (ii) the optionee makes or
attempts to make any unauthorized use or disclosure of confidential

                                       5.
<PAGE>

information or trade secrets of the Company or its parent or subsidiary
corporations, then in any such event all outstanding options granted the
optionee under the Plan shall terminate and cease to be exercisable 30 days
after such termination of Employee status or such unauthorized use or disclosure
of confidential or secret information or attempt thereat.

          E.   For purposes of the foregoing provisions of this Section V.3 (and
all other provisions of the Plan), the optionee shall be deemed to be an
"Employee" of the Company for so long as the optionee remaining in the employ of
the Company or one or more of its parent or subsidiary corporations.

          F.   If the option is to be granted to an individual who is not an
Employee of the Company, then the option agreement evidencing the granted option
shall include provisions comparable to subparagraphs V.3.A, C and D above, with
respect to the optionee's termination of service with the Company or its parent
or subsidiary corporations.

     4.   Shareholder Rights. An optionee shall have none of the rights of a
shareholder with respect to any shares covered by the option until such
individual shall have exercised the option and paid the option price.

     5.   Right of First Refusal. The Plan Administrator may in its discretion
establish as a term and condition of one or more options granted under the Plan
that the Company shall have a right of first refusal with respect to any
proposed sale or other disposition by the optionee (or any successor in interest
by reason of purchase, gift or other mode of transfer) of any shares of Common
Stock issued upon the exercise of such options. Any such right of first refusal
shall be exercisable by the Company (or its assignees) in accordance with the
terms and conditions set forth in the instrument evidencing such right.

VI.  Incentive Options.

     The terms and conditions specified below shall be applicable to all
Incentive Options granted under the Plan. Incentive Options may only be granted
to individuals who are Employees of the Company. Options which are specifically
designated as "non-statutory" options when issued under the Plan shall not be
subject to such terms and conditions.

     (a)  Option Price. The option price per share of the Common Stock subject
to an Incentive Option shall in no event be less than one hundred percent (100%)
of the fair market value of a share of Common Stock on the date of grant.

     (b)  Dollar Limitation. The aggregate fair market value (determined as of
the respective date or dates of grant) of the Common Stock for which one or more
options granted to any Employee after December 31, 1986 under the Plan (or any
other option plan of the Company or its parent or subsidiary corporations) may
for the first time become exercisable as Incentive Options during any one
calendar year shall not exceed the sum of One Hundred Thousand Dollars
($100,000). To the extent the Employee holds two or more such options which
become exercisable for the first time in the same calendar year, the foregoing
limitation on the exercisability thereof as Incentive Options shall be applied
on the basis of the order in which such options are granted.

                                       6.
<PAGE>

     Except as modified by the preceding provisions of this Section VI, all the
provisions of the Plan shall be applicable to the Incentive Options granted
hereunder.

VII.  Corporate Transactions.

      (a)  In the event of any of the following transactions (a "Corporate
Transaction"):

           (i)   a merger or acquisition in which the Company is not the
surviving entity, except for a transaction the principal purpose of which is to
change the State of the Company's incorporation, or

           (ii)  any reverse merger in which the Company is the surviving entity
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, (1) the surviving or acquiring
entity shall assume any options outstanding under the Plan or shall substitute
similar options for those outstanding under the Plan, or (2) the options
outstanding under the Plan shall continue in full force and effect. In the event
the surviving or acquiring entity refuses to assume or continue such options, or
to substitute similar options for those outstanding under the Plan, then, such
options shall be terminated if not exercised prior to the consummation of the
Corporate Transaction. In the event of a dissolution or liquidation of the
Company, any options outstanding under the Plan shall terminate if not exercised
prior to such event.

      (b)  If the Company is the surviving entity in any merger or other
business combination, then each option which remains outstanding under the Plan
immediately after such merger or other business combination shall be
appropriately adjusted to apply and pertain to the number and class of
securities which would be issuable, in consummation of such merger or business
combination, to an actual holder of the same number of shares of Common Stock as
are subject to such option immediately prior to such merger or business
combination, and appropriate adjustments shall also be made to the option price
payable per share, provided the aggregate option price payable for such option
shall remain the same. Appropriate adjustments shall also be made to the class
and number of securities available for issuance under the Plan following the
consummation of such merger or business combination.

      (c)  The grant of options under this Plan shall in no way affect the right
of the Company to adjust, reclassify, reorganize or otherwise change its capital
or business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

VIII.  Cancellation And New Grant Of Options.

      The Plan Administrator shall have the authority to effect, at any time and
from time to time, with the consent of the affected optionees, the cancellation
of any or all outstanding options under the Plan and to grant in substitution
therefor new options under the Plan covering the same or different numbers of
shares of Common Stock but having an option price per share not less than
eighty-five percent (85%) of fair market value (one hundred percent (100%) of
fair market

                                       7.
<PAGE>

value in the case of an Incentive Option or, in the case of a 10% Shareholder,
not less than one hundred and ten percent (110%) of fair market value) on the
new grant date.

IX.  Surrender Of Options For Cash Or Stock.

     (a)  Provided, and only if the Plan Administrator determines in its
discretion to implement stock appreciation right provisions of this Section IX,
one or more optionees may be granted the right, exercisable upon such terms and
conditions as the Plan Administrator may establish at the time of the option
grant or at any time thereafter, to surrender all or part of an unexercised
option under the Plan in exchange for a distribution from the Company equal in
amount to the excess of (i) the fair market value (at date of surrender) of the
number of shares in which the optionee is at the time vested under the
surrendered option or portion thereof over (ii) the aggregate option price
payable for such vested shares.

     (b)  No surrender of an option shall be effective hereunder unless it is
approved by the Plan Administrator. If the surrender is so approved, then the
distribution to which the optionee shall accordingly become entitled under this
Section IX may be made in shares of Common Stock valued at fair market value at
date of surrender, in cash, or partly in shares and partly in cash, as the Plan
Administrator shall in its sole discretion deem appropriate.

     (c)  If the surrender of an option is rejected by the Plan Administrator,
then the optionee shall retain whatever rights the optionee had under the
surrendered option (or surrendered portion thereof) on the date of surrender and
may exercise such rights at any time prior to the later of (i) the receipt of
the rejection notice or (ii) the last day on which the option is otherwise
exercisable in accordance with the terms of the instrument evidencing such
option, but in no event may such rights be exercised at any time after ten (10)
years (or five (5) years in the case of a 10% Shareholder) after the date of the
option grant.

     (d)  Notwithstanding the foregoing provisions of this Section IX, should
twenty-five percent (25%) or more of the Company's outstanding voting stock be
acquired, at a time when one or more classes of the Company's equity securities
are registered under Section 12(g) of the Securities Exchange Act of 1934 (as
amended), pursuant to a tender or exchange offer (I) which is made by a person
or group of related persons other than the Company or a person that directly or
indirectly controls, is controlled by or is under common control with the
Company and (II) which the Board does not recommend the Company's shareholders
to accept, then each officer or director who is at the time subject to the
short-swing profit restrictions of the Federal securities laws shall have the
right (exercisable for a period not to exceed thirty (30) days) to surrender any
or all options held by such individual under this Plan, to the extent such
options are at the time exercisable for vested shares, and receive in exchange
therefor an appreciation distribution equal in an amount to the excess of (i)
the fair market value (on the date of surrender) of the number of shares in
which the optionee is at the time vested under the surrendered option or portion
thereof over (ii) the aggregate option price payable for such vested shares. For
purposes of this Section IX(d), the fair market value per share of the vested
Common Stock subject to the surrendered option shall be deemed to be equal to
the greater of (a) the value per share on the date of surrender, as determined
in accordance with the valuation provisions of Section V.l.D., or, if
applicable, (b) the highest reported price per share paid in effecting the
tender or exchange offer. However, if the surrendered option is an Incentive
Option, then the fair market value of the

                                       8.
<PAGE>

vested shares subject to the surrendered option shall not exceed the value per
share determined under clause (a). The approval of the Board shall not be
required for such surrender, and the distribution to which such individual shall
become entitled upon such surrender shall be made entirely in cash.

X.  Loans Or Guarantee Of Loans.

     The Plan Administrator may assist any optionee (including any officer or
director) in the exercise of one or more options granted to such optionee under
the Plan by (a) authorizing the extension of a loan to such optionee from the
Company, (b) permitting the optionee to pay the option price for the purchased
Common Stock in installments over a period of years or (c) authorizing a
guarantee by the Company of a third party loan to the optionee. The terms of any
loan, installment method of payment or guarantee (including the interest rate
and terms of repayment) will be established by the Plan Administrator in its
sole discretion. Loans, installment payments and guarantees may be granted
without security or collateral (other than to optionees who are consultants or
independent contractors, in which event the loan must be adequately secured by
collateral other than the purchased shares), but the maximum credit available to
the optionee shall not exceed the sum of (i) that portion of the aggregate
option price in the excess of the amount determined to be capital pursuant to
Section 154 of the Delaware Corporation Law, plus (ii) any federal and state
income and employment tax liability incurred by the optionee in connection with
the exercise of the option.

XI.  Extension Of Exercise Period.

     The Plan Administrator shall have full power and authority, exercisable in
its sole discretion to extend, either at any time while the option is granted or
at the time while the option remains outstanding, the period of time for which
the option is to remain exercisable following the optionee's termination of
Employee status (the "Exercise Period") from the twelve (12) month or shorter
period set forth in the option agreement to such greater period of time as the
Plan Administrator shall deem appropriate; provided, however, that in no event
shall such option be exercisable after the specified expiration date of the
option term; and provided, that in accordance with Section 422 of the Internal
Revenue Code, the Exercise Period with respect to an Incentive Option shall not
be extended beyond three (3) months after the date of termination, unless such
termination is due to (i) a permanent and total disability, in which case the
Exercise Period may be up to one (1) year, or (ii) death, in which case the
Exercise Period may be up to eighteen (18) months.

XII.  Amendment Of The Plan.

     The Board shall have complete and exclusive power and authority to amend or
modify the Plan in any or all respects whatsoever; provided, however, that no
such amendment or modification shall, without the consent of the holders,
adversely affect rights and obligations with respect to options at the time
outstanding under the Plan; and provided, further, that the Board shall not,
without the approval of the stockholders of the Company (i) increase the maximum
number of shares issuable under the Plan, except for permissible adjustments
under Section IV(c), (ii) materially modify the eligibility requirements for the
grant of options under the Plan or (iii) otherwise materially increase the
benefits accruing to participants under the Plan.

                                       9.

XIII.  Effective Date And Term Of Plan.

     (a)  The Plan shall become effective when adopted by the Board, but no
option granted under the Plan shall become exercisable unless and until the Plan
shall have been approved by the stockholders of the Company. If such stockholder
approval is not obtained within twelve (12) months after the date of the Board's
adoption of the Plan, then all options previously granted under the Plan shall
terminate and no further options shall be granted. Subject to such limitation,

issuable under the Plan is adopted by the Board prior to the initial grant of
any such option and within one year thereafter such amendment is approved by the
stockholders of the Company and (ii) each option granted is not to become

                                  -----------
                            STOCK OPTION AGREEMENT
                            ----------------------

          AGREEMENT made as of "grantdate", by and between Telik, Inc., a
Delaware corporation (hereinafter called "Company"), and "fname" "Lname"
(hereinafter called "Optionee").

                                  WITNESSETH:
                                  ----------

RECITALS
--------

          A.  The Board of Directors of the Company has adopted the Company's
1988 Stock Option Plan (the "Plan") for the purpose of attracting and retaining
the services of selected employees (including officers and directors), who
contribute to the financial success of the Company or its parent or subsidiary
corporations.  This option is granted under the Plan.

          B.  Optionee is an employee of the Company or its parent or subsidiary
corporations, and this Agreement is executed pursuant to, and is intended to
carry out the purposes of, the Plan in connection with the Company's grant of a
stock option to Optionee.

          C.  The granted option is intended to be an Incentive Stock Option
("Incentive Option") within the meaning of Section 422 of the Internal Revenue
Code, as amended (the "Code").

          NOW, THEREFORE, it is hereby agreed as follows:

          1.   Grant of Option. Subject to and upon the terms and conditions set
               ---------------
forth in this Agreement and in the Plan, there is hereby granted to Optionee, as
of "grantdate" (the "Grant Date"), a stock option to purchase up to
"wordsnumbrshrs" ("numbershres") shares of the Company's Common Stock (the
"Optioned Shares") from time to time during the option term at the option price
of "expricewrds" ("exprice") per share (the "Option Price").

          2.   Option Term. This option shall have a maximum term of ten (10)
               -----------
years measured from the Grant Date and shall accordingly expire at the close of
business on "expirdate" (the "Expiration Date"), unless sooner terminated in
accordance with paragraph 5, 7(a), or 20.

          3.   Option Nontransferable; Exception.  This option shall be neither
               ---------------------------------
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution and may be exercised, during Optionee's lifetime, only
by Optionee.

          4.   Dates of Exercise. Optionee shall have no right to purchase any
               -----------------
Optioned Shares prior to the expiration of the twelve (12)-month period measured
from "veststdate" (the "Vesting Commencement Date") of this option. Thereafter
Optionee may, within the specified term of this option and pursuant to the
provisions of this Agreement, purchase the Optioned Shares in accordance with
the following schedule:

               (i)  Twenty Percent (25%) of the Optioned Shares at any time
after the expiration of twelve (12) months measured from the Vesting
Commencement Date ("vestst12 months").

                                      1.
<PAGE>

               (ii)   The balance of the Optioned Shares in a series of thirty
six (36) consecutive monthly installments, at a rate of 1/48 of the Optioned
Shares, with the first such installment to become exercisable upon the
expiration of the thirteenth (13th) calendar month from the Vesting Commencement
Date.

          5.   Accelerated Termination of Option Term. The option term specified
               --------------------------------------
in paragraph 2 shall terminate (and this option shall cease to be exercisable)
prior to the Expiration Date should one of the following provisions become
applicable:

               (i)    Except as otherwise provided in subparagraphs (ii), (iii)
or (iv) below, should Optionee cease to be a Employee at any time during the
option term, then the Optionee shall have up to a three (3) month period
commencing with the date of such cessation of Employee status, in which to
exercise this option for any or all of the Optioned Shares for which this option
is, in accordance with paragraph 4, exercisable at the time of such cessation of
Employee status, but in no event shall this option be exercisable at any time
after the Expiration Date. Upon the expiration of such three (3) month period or
(if earlier), upon the Expiration Date, this option shall terminate and cease to
be outstanding.

               (ii)   Should Optionee die while this option is outstanding, then
the personal representative of the Optionee's estate or the person or persons to
whom the option is transferred pursuant to the Optionee's will or in accordance
with the law of descent and distribution shall have the right to exercise this
option provided and only if such exercise occurs prior to the earlier of (A) the
expiration of the twelve (12) month period measured from the date of Optionee's
death or (B) the Expiration Date. During such period of limited exercisability,
this option may be exercised for any or all of the Optioned Shares for which
this option is, in accordance with paragraph 4, exercisable at the time of the
Optionee's cessation of Employee status. Upon the expiration of such twelve (12)
month period or (if earlier), upon the Expiration Date, this option shall
terminate and cease to be outstanding.

               (iii)  Should Optionee become permanently disabled, as defined in
Section 22(e)(3) of the Code, and cease by reason thereof to be a Employee at
any time during the option term, then the Optionee shall have a period of twelve
(12) months (commencing with the date of such cessation of Employee status) in
which to exercise this option for any or all of the Optioned Shares for which
this option is, in accordance with paragraph 4, exercisable at the time of such
cessation of Employee status; provided, however, that in no event shall this
option be exercisable at any time after the Expiration Date. Upon the expiration
of such limited period of exercisability or (if earlier), upon the Expiration
Date, this option shall terminate and cease to be outstanding.

               (iv)   Should the Optionee's status as an Employee be terminated
for misconduct (including, but not limited to, any act of dishonesty, willful
misconduct, fraud or embezzlement or any unauthorized disclosure or use of
confidential information or trade secrets) or should the Optionee make or
attempt to make any unauthorized use or disclosure of the confidential
information or trade secrets of the Company or any parent or subsidiary
corporation, then in any such event this option shall terminate and cease to be
exercisable thirty (30) days after such termination of Employee status or such
unauthorized disclosure or use of confidential or secret information or attempt
thereat.

               (v)    For purposes of this paragraph 5 and for all other
purposes under this Agreement, the Optionee shall be deemed to be a Employee and
to continue in the Company's employ for so long as the Optionee remains in the
employ of the Company or one or more of its parent or subsidiary corporations.
In applying the provisions of this Agreement, a corporation shall be considered
to be a subsidiary corporation of the Company if it is a member of an unbroken
chain of corporations beginning with the Company, provided each such corporation
in the chain (other than the last corporation) owns, at the time of
determination, stock possessing 50% or more of the total combined voting power
of all classes of stock in one of the other corporations in such chain. A
corporation shall be considered to be a parent corporation of the Company if it
is a member of an unbroken chain ending with the Company, provided each such
corporation in the chain (other than the last corporation) owns, at the time of
determination, stock possessing 50% or more of the total combined voting power
of all classes of stock in one of the other corporations in such chain. A
corporation shall be considered to be a parent corporation of the Company if it
is a member of an unbroken chain ending with the Company, provided each such
corporation in the chain (other than the Company) owns, at the time of
determination, stock possessing 50% or more of the total combined voting power
of all classes of stock in one of the other corporations in such chain.

                                      2.

          6.   Adjustment in Optioned Shares.
               -----------------------------

          (a)  In the event any change is made to the Common Stock issuable
under the Plan by reason of any stock split, stock dividend, combination of
shares, or other change affecting the outstanding Common Stock as a class
without receipt of consideration, then appropriate adjustments will be made to
(i) the total number of Optioned Shares subject to this option, (ii) the number
of Optioned Shares for which this option may be exercised on each relevant date
under paragraph 4 and (iii) the Option Price payable per share in order to
reflect such change and thereby preclude a dilution or enlargement of benefits
hereunder.

          (b)  If the Company is the surviving entity in any merger or other
business combination, then this option, if outstanding under the Plan
immediately after such merger or other business combination, shall be
appropriately adjusted to apply and pertain to the number and class of
securities which would be issuable to the Optionee in respect of shares held by
the Optionee pursuant to this option in the consummation of such merger or
business combination if the option were exercised immediately prior to such
merger or business combination, and appropriate adjustments shall also be made
to the Option Price payable per share, provided the aggregate Option Price
payable hereunder shall remain the same.

          7.   Special Termination of Option.
               -----------------------------

          (a)  In the event of one or more of the following transactions (a
"Corporate Transaction"):

               (i)   a merger or acquisition in which the Company is not the
surviving entity, except for a transaction the principal purpose of which is to
change the State of the Company's incorporation, or

               (ii)  any reverse merger in which the Company is the surviving
entity 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, the exercisability of this option shall
automatically be accelerated so that such option shall, during the five (5)
business day period immediately prior to the specified effective date for the
Corporate Transaction, become fully exercisable with respect to the Optioned
Shares and may be exercised for all or any portion of such shares; provided,
however, that the exercisability of the accelerated option as an incentive stock
option under the federal tax laws shall remain subject to the applicable
limitations of paragraph 23. No such acceleration of this option, however, shall
occur if and to the extent this option is, in connection with the Corporate
Transaction, either to be assumed by the successor corporation or parent thereof
or be replaced with a comparable option to purchase shares of the capital stock
of the successor corporation or parent thereof. The determination of such
comparability shall be made by the Plan Administrator and its determination
shall be final, binding and conclusive. This option, to the extent not
previously exercised, shall terminate upon the consummation of such Corporate
Transaction and cease to be exercisable, unless it is expressly assumed by the
successor corporation or parent thereof.

          (b)  This Agreement shall not in any way affect the right of the
Company to adjust, reclassify, reorganize or otherwise make changes in its
capital or business structure or to merge, consolidate, dissolve, liquidate or
sell or transfer all or any part of its business or assets.

          8.   Privilege of Stock Ownership. The holder of this option shall not
               ----------------------------
have any of the rights of a shareholder with respect to the Optioned Shares
until such individual shall have exercised the option and paid the Option Price.

          9.   Manner of Exercising Option.
               ---------------------------

          (a)  In order to exercise this option with respect to all or any part
of the Optioned Shares for which this option is at the time exercisable,
Optionee (or in the case of exercise after Optionee's death, the Optionee's
executor, administrator, heir or legatee, as the case may be) must take the
following actions:

               (i)   Execute and deliver to the Secretary of the Company a stock
purchase agreement in the form attached to this Agreement (the "Purchase
Agreement");

                                      3.
<PAGE>

               (ii)   Pay the aggregate Option Price for the purchased shares in
one or more of the following alternative forms:

                      (A)  Full payment, in cash or cash equivalents; or

                      (B)  Full payment in shares of Common Stock of the Company
held by the Optionee for the requisite period necessary to avoid a charge to the
Company's reported earnings and valued at Fair Market Value on the Exercise Date
(as such terms are defined below) in an amount equal to the Option Price; or

                      (C)  Full payment in a combination of shares of Common
Stock of the Company held by the Optionee for the requisite period necessary to
avoid a charge to the Company's reported earnings and valued at Fair Market
Value on the Exercise Date and cash or cash equivalents, equal in the aggregate
to the Option Price; or

                      (D)  Any other form which the Plan Administrator may, in
its discretion, approve at the time of exercise in accordance with the
provisions of paragraph 18 of this Agreement; and

               (iii)  Furnish to the Company appropriate documentation that the
person or persons exercising the option, if other than Optionee, have the right
to exercise this option.

               (iv)   Execute whatever documents are reasonably deemed necessary
by the Board of Directors of the Company in order for the Company and the
Optionee to comply with the then current laws and regulations regarding the
issue of securities by the Company.

          (b)  For purposes of paragraph 9(a) above, the Fair Market Value of a
share of Common Stock shall be determined in accordance with subparagraphs (i)
through (iii) below, and the Exercise Date shall be the first date on which
there shall have been delivered to the Company both (I) the executed Purchase
Agreement and (II) the payment of the Option Price for the purchased shares.

               (i)    If the Common Stock is not on the Exercise Date listed or
admitted to trading on any stock exchange, but is traded in the over-the-counter
market, the Fair Market Value shall be the mean between the highest bid and
lowest asked prices (or if such information is available, the closing selling
price) of one share of Common Stock on the Exercise Date in the over-the-counter
market, as such prices are reported by the National Association of Securities
Dealers through its NASDAQ system or any successor system. If there are no
reported bid and asked prices (or closing selling price) for the Common Stock on
the Exercise Date, then the mean between the highest bid and the lowest asked
prices (or closing selling price) on the last preceding date for which such
quotations exist shall be determinative of Fair Market Value.

               (ii)   If the Common Stock is on the Exercise Date listed or
admitted to trading on any stock exchange, then the Fair Market Value shall be
the closing selling price of one share of Common Stock on the Exercise Date on
the stock exchange determined by the Plan Administrator to be the primary market
for the Common Stock, as such price is officially quoted in the composite tape
of transactions on such exchange. If there is no reported sale of Common Stock
on such exchange on the Exercise Date, then the Fair Market Value shall be the
closing selling price on the exchange on the last preceding date for which such
quotation exists.

               (iii)  If the Common Stock is on the Exercise Date neither listed
or admitted to trading on any stock exchange nor traded in the over-the-counter
market, then the Fair Market Value shall be determined by the Board of Directors
of the Company after taking into account such factors as they shall deem
appropriate.

          (c)  This option shall be deemed to have been exercised with respect
to the number of Optioned Shares specified in the Purchase Agreement at such
time as the executed Purchase Agreement for such shares shall have been
delivered to the Company. Payment of the Option Price shall immediately become
due and shall accompany the Purchase Agreement. As soon thereafter as practical,
the Company shall mail or deliver to

                                      4.
<PAGE>

Optionee or to the other person or persons exercising this option a certificate
or certificates representing the shares so purchased and paid for, with the
appropriate legends affixed thereto.

          (d)  In no event may this option be exercised for any fractional
shares.

          10.  RIGHTS OF FIRST REFUSAL. THE OPTIONEE HEREBY AGREES THAT ALL
               -----------------------
OPTIONED SHARES ACQUIRED UPON THE EXERCISE OF THIS OPTION SHALL BE SUBJECT TO
CERTAIN RIGHTS OF THE COMPANY AND ITS ASSIGNS TO REPURCHASE SUCH SHARES IN
ACCORDANCE WITH THE TERMS AND CONDITIONS SPECIFIED IN THE "PURCHASE AGREEMENT,"
A COPY OF WHICH IS ATTACHED TO THIS AGREEMENT.

          11.  Compliance with Laws and Regulations.
               ------------------------------------

          (a)  The exercise of this option and the issuance of Optioned Shares
upon such exercise shall be subject to compliance by the Company and the
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange on which shares of the Company's
Common Stock may be listed at the time of such exercise and issuance.

          (b)  In connection with the exercise of this option, Optionee shall
execute and deliver to the Company such representations in writing as may be
requested by the Company in order for it to comply with the applicable
requirements of federal and state securities laws.

          (c)  Optionee understands that, when issued, with regard to the
purchased shares:

               (i)   Exemption from Registration. The purchased shares will not
                     ---------------------------
     have been registered under the Securities Act of 1933, as amended (the
     "1933 Act") and will be issued to Optionee in reliance upon the exemption
     from such registration provided by Rule 701 of the Securities and Exchange
     Commission for stock issuances under compensatory benefit plans.

               (ii)  Restricted Securities. Optionee will confirm that Optionee
                     ---------------------
has been informed that the purchased shares are restricted securities under the
1933 Act and may not be resold or transferred unless the purchased shares are
first registered under the Federal securities laws or unless an exemption from
such registration is available. Accordingly, Optionee will acknowledge that
Optionee is prepared to hold the purchased shares for an indefinite period and
that Optionee is aware that Rule 144 of the Securities and Exchange Commission
issued under the 1933 Act is not presently available to exempt the sale of the
purchased shares from the registration requirements of the 1933 Act. Upon the
expiration of the ninety (90)-day period immediately following the date on which
the Corporation first becomes subject to the reporting requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), the purchased
shares may be sold (without registration) pursuant to the applicable
requirements of Rule 144. If Optionee is at the time of such sale an affiliate
of the Corporation for purposes of Rule 144 or was an affiliate during the
preceding three (3) months, then the sale must comply with all the requirements
of Rule 144 (including the volume limitation on the number of shares sold, the
broker/market maker sale requirement and the requisite notice to the Securities
and Exchange Commission); however, the two-year holding period requirement of
the Rule will not be applicable. If Optionee is not at the time of the sale an
affiliate of the Corporation nor was Optionee an affiliate during the preceding
three (3) months, then none of the requirements of Rule 144 (other than the
broker/market maker sale requirement for purchased shares held for less than
three (3) years following payment in cash of the Option Price therefor) will be
applicable to the sale. Should the Corporation not become subject to the
reporting requirements of the Exchange Act, then Optionee may, provided he/she
is neither at the time an affiliate of the Corporation nor was an affiliate
during the preceding three (3) months, sell the purchased shares (without
registration) pursuant to paragraph (k) of Rule 144 after the purchased shares
have been held for a period of three (3) years following the payment in cash of
the Option Price for such shares.

          (d)  Restrictive Legends. In order to reflect the restrictions on
               -------------------
disposition of the purchased shares, the stock certificates for the purchased
shares will be endorsed with restrictive legends, including one or both of the
following legends:

                                      5.
<PAGE>

               (i)   "The shares represented by this certificate have not been
registered under the Securities Act of 1933. The shares may not be sold or
offered for sale in the absence of (a) an effective registration statement for
the shares under such Act, (b) a "no action" letter of the Securities and
Exchange Commission with respect to such sale or offer, or (c) satisfactory
assurances to the Company that registration under such Act is not required with
respect to such sale or offer."

               (ii)  "It is unlawful to consummate a sale or transfer of this
security, or any interest therein, or to receive any consideration therefor,
without the prior written consent of the Commissioner of Corporations of the
State of California, except as permitted in the Commissioner's Rules."

          (e)  Receipt of Commissioner Rules. Optionee will receive a copy of
               -----------------------------
Section 260.141.11 of the Rules of the California Corporations Commissioner upon
the grant of this option, a copy of which is attached to this Agreement.

          12.  Successors and Assigns. Except to the extent otherwise provided
               ----------------------
in paragraph 3, the provisions of this Agreement shall inure to the benefit of,
and be binding upon, the successors, administrators, heirs, legal
representatives and assigns of Optionee and the successors and assigns of the
Company.

          13.  Liability of Company.
               --------------------

          (a)  If the Optioned Shares covered by this Agreement exceed, as of
the Grant Date, the number of shares of Common Stock which may without
shareholder approval be issued under the Plan, then this option shall be void
with respect to such excess shares unless shareholder approval of an amendment
sufficiently increasing the number of shares of Common Stock issuable under the
Plan is obtained in accordance with the provisions of the Plan.

          (b)  The inability of the Company to obtain approval from any
regulatory body having authority deemed by the Company to be necessary to the
lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Company of any liability with respect to the non-issuance or sale of
the Common Stock as to which such approval shall not have been obtained. The
Company, however, shall use its best efforts to obtain all such approvals.

          14.  No Employment Contract. Nothing in this Agreement shall confer
               ----------------------
upon the Optionee any right to continue in the employ of the Company (or any
parent or subsidiary corporation of the Company employing Optionee) for any
period of time or interfere with or restrict in any way the rights of the
Company (or any parent or subsidiary corporation of the Company employing
Optionee) or the Optionee, which rights are hereby expressly reserved by each,
to terminate the Employee status of Optionee at any time for any reason
whatsoever, with or without cause.

          15.  Notices. Any notice required to be given or delivered to the
               -------
Company under the terms of this Agreement shall be in writing and addressed to
the Company in care of it's Secretary, at its corporate offices. Any notice
required to be given or delivered to Optionee shall be in writing and addressed
to Optionee at the address indicated below Optionee's signature line on this
Agreement. All notices shall be deemed to have been given or delivered upon
personal delivery or upon deposit in the U.S. mail, postage prepaid and properly
addressed to the party to be notified.

          16.  Withholding. Optionee hereby agrees to make appropriate
               -----------
arrangements with the Company or subsidiary corporation employing Optionee (if
any) for the satisfaction of any federal, state or local income tax withholding
requirements and federal social security employee tax requirements applicable to
the exercise of this option.

          17.  Loans or Guarantees.  The Plan Administrator may, in its absolute
               -------------------
discretion and without any obligation to do so, assist the Optionee in the
exercise of this option by (i) authorizing the extension of a loan to the
Optionee from the Company, (ii) permitting the Optionee to pay the Option Price
for the purchased Common Stock in installments over a period of years, or (iii)
authorizing a guarantee by the Company of a third

                                      6.
<PAGE>

party loan to the Optionee. The terms of any loan, installment method of payment
or guarantee (including the interest rate, the collateral requirements and terms
of repayments) shall be established by the Plan Administrator in its sole
discretion.

          18.  Construction. This Agreement and the option evidenced hereby are
               ------------
made and granted pursuant to the Plan and are in all respects limited by and
subject to the express terms and provisions of the Plan. All decisions of the
Plan Administrator of the Company with respect to any question or issue arising
under this Agreement shall be conclusive and binding upon all persons having an
interest in this option.

          19.  Governing Law. The interpretation, performance, and enforcement
               -------------
of this Agreement shall be governed by the laws of the State of California.

          20.  Counterparts. This Agreement may be executed in counterparts,
               ------------
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

          21.  Loss of Favorable Tax Treatment.
               -------------------------------

          (a)  This option shall cease to qualify for favorable tax treatment as
an incentive stock option under the federal tax laws if (and to the extent) this
option is exercised for one or more Optioned Shares: (i) more than three (3)
months after the date the Optionee ceases to be an Employee for any reason other
than death or permanent disability (as defined in paragraph 5) or (ii) more than
one (1) year after the date and the Optionee dies or ceases to be an Employee by
reason of permanent disability.

          (b)  Except to the extent the exercisability of this option is
otherwise to be accelerated upon a Corporate Transaction in accordance with
paragraph 7, this option shall not become exercisable in the calendar year in
which granted if (and to the extent) the aggregate Fair Market Value (determined
at the Grant Date) of the Company's Common Stock for which this option would
otherwise first become exercisable in such calendar year would, when added to
the aggregate Fair Market Value (determined as of the respective date or dates
of grant) of the Company's Common Stock for which this option or one or more
other post-1986 Incentive Options granted to the Optionee prior to the Grant
Date (whether under the Plan or any other option plan of the Company or its
parent or subsidiary corporations) first become exercisable during the same
calendar year, exceed $100,000 in the aggregate. To the extent the
exercisability of this option is deferred by reason of the foregoing limitation,
the deferred portion will first become exercisable in the first calendar year or
years thereafter in which the $100,000 limitation of this paragraph 23(b) would
not be contravened.

          (c)  Should the exercisability of this option be accelerated upon a
Corporate Transaction in accordance with paragraph 7, then this option shall
qualify for favorable tax treatment as an incentive stock option under the
federal tax laws only to the extent the aggregate Fair Market Value (determined
at the Grant Date) of the Company's Common Stock for which this option first
becomes exercisable in the calendar year in which the Corporate Transaction
occurs does not when added to the aggregate Fair Market Value (determined as of
the respective date or dates of grant) of the Company's Common Stock for which
this option or one or more other post-1986 Incentive Options granted to the
Optionee prior to the Grant Date (whether under the Plan or any other option
plan of the Company or any parent or subsidiary corporations) first become
exercisable during the same calendar year, exceed $100,000 in the aggregate.

          (d)  To the extent this option should fail to qualify as an incentive
option under the federal tax laws, the Optionee will recognize compensation
income in connection with the acquisition of one or more Optioned Shares
hereunder, and the Optionee must make appropriate arrangements for the
satisfaction of all federal, state or local income tax withholding requirements
and federal social security employee tax requirements applicable to such
compensation income.

                                                          RIGHT OF FIRST REFUSAL
                                                          ----------------------

                           STOCK PURCHASE AGREEMENT
                           ------------------------

     This Agreement is made as of this _______ day of __________________ ,
19____, by and among Terrapin Technologies, Inc. a Delaware corporation
("Corporation"), ______________, the holder of a stock option under the
Corporation's 1988 Stock Option Plan ("Optionee"), and (not applicable), the
optionee's spouse.

I.   EXERCISE OF OPTION
     ------------------

          1.1  Exercise.  Optionee hereby purchases ____________ shares of
               --------
Common Stock of the Corporation ("Purchased Shares") pursuant to that certain
option ("Option") granted Optionee on July 5, 1995, ("Grant Date") under the
Corporation's 1988 Stock Option Plan ("Plan") to purchase up to _________ shares
of the Corporation's Common Stock at an option price of _____ per share ("Option
Price").

          1.2  Payment.  Concurrently with the delivery of this Agreement to
               -------
the Secretary of the Corporation, Optionee shall pay the Option Price for the
Purchased Shares in accordance with the provisions of the agreement between the
Corporation and Optionee evidencing the Option ("Option Agreement") and shall
deliver whatever additional documents may be required by the Option Agreement as
a condition for exercise.

II.  SECURITIES LAW COMPLIANCE
     -------------------------

          2.1  Exemption from Registration.  The Purchased Shares have not been
               ---------------------------
registered under the Securities Act of 1933, as amended (the "1933 Act") and are
being issued to Optionee in reliance upon the exemption from such registration
provided by Rule 701 of the Securities and Exchange Commission for stock
issuances under compensatory benefit plans such as the Plan. Optionee hereby
acknowledges receipt of a copy of the documentation for such Plan.

          2.2  Restricted Securities.  Optionee hereby confirms that Optionee
               ---------------------
has been informed that the Purchased Shares are restricted securities under the
1933 Act and may not be resold or transferred unless the Purchased Shares are
first registered under the Federal securities laws or unless an exemption from
such registration is available. Accordingly, Optionee hereby acknowledges that
Optionee is prepared to hold the Purchased Shares for an indefinite period and
that Optionee is aware that Rule 144 of the Securities and Exchange Commission
issued under the 1933 Act is not presently available to exempt the sale of the
Purchased Shares from the registration requirements of the 1933 Act. Upon the
expiration of the ninety (90)-day period immediately following the date on which
the Corporation first becomes subject to the reporting requirements of the
Securities Exchange Act 1934, as amended (the "Exchange Act"), the Purchased
Shares may be sold (without registration) pursuant to the applicable
requirements of Rule 144. If optionee is at the time of such sale an affiliate
of the Corporation for purposes of Rule 144 or was such an affiliate during the
preceding three (3) months, then the sale must comply with all the requirements
of Rule 144 (including the volume limitation on the number of shares sold, the
broker/market maker sale requirement and the requisite notice to the Securities
and Exchange Commission); however, the two-year holding period requirement of
the Rule will not be applicable. If Optionee is not at the time of the sale an
affiliate during the preceding three (3) months, then none of the requirements
of Rule 144 (other than the broker/market maker sale requirement for Purchased
Shares held for less than three (3) years following payment in cash of the
Option Price therefor) will be applicable to the sale. Should the Corporation
not become subject to the reporting requirements of the Exchange Act, then
optionee may, provided he/she is neither at the time an affiliate of the
Corporation nor was such an affiliate during the preceding three (3) months,
sell the Purchased Shares (without registration) pursuant to paragraph (k) of
Rule 144 after the Purchased Shares have been held for a period of three (3)
years following the payment in cash of the Option Price for such shares.

          2.3  Disposition of Shares.  Optionee hereby agrees that Optionee
               ---------------------
shall make no disposition of the Purchased Shares (other than a permitted
transfer under paragraph 3.1) unless and until:

                                  pg. 1 of 10
<PAGE>

          (a)  Optionee shall have notified the Corporation of the proposed
disposition and provided a written summary of the terms and conditions of the
proposed disposition;

          (b)  Optionee shall have complied with all requirements of this
Agreement applicable to the disposition of the Purchased Shares; and

          (c)  Optionee shall have provided the Corporation with written
assurances, in form and substance satisfactory to the Corporation, that (i) the
proposed disposition does not require registration of the Purchased Shares under
the 1933 Act (ii) all appropriate action necessary for compliance with the
registration requirements of the 1933 Act or of any exemption from registration
available under the 1933 Act (including Rule 144) has been taken.

          (d)  Optionee shall have provided the Corporation with written
assurances, in form and substance satisfactory to the Corporation, that the
proposed disposition will not result in the contravention of any transfer
restrictions applicable to the Purchased Shares Pursuant to the provisions of
the Commissioner Rules identified in paragraph 2.5.

     The Corporation shall not be required (i) to transfer on its books any
                           ---
Purchased Shares which have been sold or transferred in violation of the
provisions of this Article II nor (ii) to treat as the owner of the Purchased
                              ---
Shares, or otherwise to accord voting or dividend rights to, any transferee to
whom the Purchased Shares have been transferred in contravention of this
Agreement.

          2.4  Restrictive Legends.  In order to reflect the restrictions on
               -------------------
disposition of the Purchased Shares, the stock certificates for the Purchased
Shares will be endorsed with restrictive legends, including one or both of the
following legends:

               (i)  "The shares represented by this certificate have not been
     registered under the Securities Act of 1933. The shares may not be sold or
     offered for sale in the absence of (a) an effective registration statement
     for the shares under such Act, (b) a `no action' letter of the Securities
     and Exchange Commission with respect to such sale offer, or (c)
     satisfactory assurances to the Corporation that registration under such Act
     is not required with respect to such sale offer."

               (ii) "It is unlawful to consummate a sale or transfer of this
     security, or any interest therein, or to receive any consideration
     therefor, without the prior written consent of the Commissioner of
     Corporations of the State of California, except as permitted in the
     Commissioner's Rules."

          2.5  Receipt of Commissioner Rules.  Optionee hereby acknowledges
               -----------------------------
receipt of a copy of Section 260.141.11 of the Rules of the California
Corporations Commissioner, a copy of which is attached as Exhibit A to this
Agreement.

          2.6  Shareholder Rights.  Until such time as the Corporation actually
               ------------------
exercises its repurchase rights under this Agreement, Optionee (or any successor
in interest) shall have all rights of a shareholder (including voting and
dividend rights) with respect to the Purchased Shares, subject, however, to the
transfer restrictions of Article III.

III. TRANSFER RESTRICTIONS
     ---------------------

          3.1  Restriction on Transfer.  Optionee shall not transfer, assign,
               -----------------------
encumber or otherwise dispose of any of the Purchased Shares in contravention of
the Corporation's First Refusal Right under Article IV. Such restrictions on
transfer, however, shall not be applicable to (i) a gratuitous transfer of the
Purchased Shares made to the Optionee's spouse or issue, including adopted
children, or to a trust for the exclusive benefit of the Optionee or the
Optionee's spouse or issue; provided and only if the Optionee obtains the
                            --------------------
Corporation's prior written consent to such transfer, (ii) a transfer of title
to the Purchased Shares effected pursuant to the Optionee's will or the laws of
intestate succession or (iii) a transfer to the Corporation in pledge as
security for any purchase-money indebtedness incurred by the Optionee in
connection with the acquisition of the Purchased Shares.


                                  pg. 2 of 10
<PAGE>

          3.2  Transferee Obligations.  Each person (other than the
               ----------------------
Corporation) to whom the Purchased Shares are transferred by means of one of the
permitted transfers specified in paragraph 3.1 must, as a condition precedent to
the validity of such transfer, acknowledge in writing to the Corporation that
such person is bound by the provisions of this Agreement and that the
transferred shares are subject to (i) the Corporation's First Refusal Right
granted hereunder, and (ii) the market stand-off provisions of paragraph 4.8, to
the same extent such shares would be so subject if retained by the Optionee.

          3.3  Definition of Owner.  For purposes of Article IV of this
               -------------------
Agreement, the term "Owner" shall include the Optionee and all subsequent
holders of the Purchased Shares who derive their chain of ownership through a
permitted transfer from the Optionee in accordance with paragraph 3.1.

IV.  RIGHT OF FIRST REFUSAL
     ----------------------

          4.1  Grant.  The Corporation is hereby granted the right of first
               -----
refusal ("First Refusal Right"), exercisable in connection with any proposed
sale or other transfer of the Purchased Shares. For purposes of this Article IV,
the term "transfer" shall include any assignment, pledge, encumbrance or other
disposition for value of the Purchased Shares intended to be made by the Owner,
but shall not include any of the permitted transfers under paragraph 3.1.

          4.2  Notice of Intended Disposition.  In the event the Owner desires
               ------------------------------
to accept a bona fide third-party offer for any or all of the Purchased Shares
(the shares subject to such offer to be hereinafter called, solely for the
purposes of this Article IV, the "Target Shares"), Owner shall promptly (i)
deliver to the Secretary of the Corporation written notice (the "Disposition
Notice") of the offer and the basic terms and conditions thereof, including the
proposed purchase price, and (ii) provide satisfactory proof that the
disposition of the Target Shares to the third-party offeror would not be in
contravention of the representations made by Optionee in Article II of this
Agreement.

          4.3  Exercise of Right.  The Corporation (or its assignees) shall,
               -----------------
for a period of twenty-five (25) days following receipt of the Disposition
Notice, have the right to repurchase any or all of the Target Shares specified
in the disposition Notice upon substantially the same terms and conditions
specified therein. Such right shall be exercisable by written notice (the
"Exercise Notice") delivered to Owner prior to the expiration of the twenty-five
(25) day exercise period. If such right is exercised with respect to all the
Target Shares specified in the Disposition Notice, then the Corporation (or its
assignees) shall effect the repurchase of the Target Shares, including payment
of the purchase price, not more than five (5) business days after the delivery
of the Exercise Notice; and at such time Owner shall deliver to the Corporation
the certificates representing the Target Shares to be repurchased, each
certificate to be properly endorsed for transfer. The Target Shares so purchased
shall thereupon be canceled and cease to be issued and outstanding shares of the
Corporation's Common Stock.

          Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation (or its assignees) shall have the right to pay the purchase price in
the form of cash equal in amount to the value of such property. If the Owner and
the Corporation (or its assignees) cannot agree on such cash value within ten
(10) days after the Corporation's receipt of the Disposition Notice, the
valuation shall be made by an appraiser of recognized standing selected by the
Owner and the Corporation (or its assignees) or, if they cannot agree on an
appraiser within twenty (20) days after the Corporation's receipt of the
Disposition Notice, each shall select an appraiser of recognized standing and
the two appraisers shall designate a third appraiser of recognized standing,
whose appraisal shall be determinative of such value. The cost of such appraisal
shall be shared equally by the Owner and the Corporation. The closing shall then
be held on the later of (i) the fifth business day following the delivery of the
               -----
Exercise Notice, or (ii) the fifth business day after such cash valuation shall
have been made.

          4.4  Non-Exercise of Right.  In the event the Exercise Notice is not
               ---------------------
given to Owner within twenty-five (25) days following the date of the
Corporation's receipt of the Disposition Notice, Owner shall have a period of
thirty (30) days thereafter in which to sell or otherwise dispose of the Target
Shares upon terms and conditions (including the purchase price) no more
favorable to the third party purchaser than those specified in the Disposition
Notice; provided, however, that any such sale or disposition must not be
        --------
effected in contravention of the provisions of Article II of this Agreement. The
third-party purchaser shall acquire the Target Shares free and clear of

                                  pg. 3 of 10
<PAGE>

all the terms and provisions of this Agreement (including the Corporation's
First Refusal Right hereunder). In the event Owner does not sell or otherwise
dispose of the Target Shares within the specified thirty (30) day period, the
Corporation's First Refusal Right shall continue to be applicable to any
subsequent disposition of the Target Shares by Owner until such right lapses in
accordance with paragraph 4.7.

          4.5  Partial Exercise of Right.  In the event the Corporation (or its
               -------------------------
assignees) makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within thirty (30) days after the date of the Disposition Notice, to
effect the sale of the Target Shares pursuant to one of the following
alternatives:

               (i)   sale or other disposition of all the Target Shares to a
     third-party purchaser in compliance with the requirements of paragraph 4.4,
     as if the Corporation did not exercise the First Refusal right hereunder;
     or

               (ii)  sale to the Corporation (or its assignees) of the portion
     of the Target Shares which the Corporation (or its assignees) has elected
     to purchase, such sale to be effected in substantial conformity with the
     provisions of paragraph 4.3.

     Failure of Owner to deliver timely notification to the Corporation under
this paragraph 4.5 shall be deemed to be an election by Owner to sell the Target
Shares pursuant to alternative (i) above.

          4.6  Recapitalization/Corporate Transaction.
               --------------------------------------

          (a)  In the event of any stock dividend, stock split, recapitalization
or other transaction affecting the Corporation's outstanding Common Stock as a
class effected without receipt of consideration, then any new, substituted or
additional securities or other property which is by reason of such transaction
distributed with respect to the Purchased Shares shall be immediately subject to
the Corporation's First Refusal right hereunder, but only to the extent the
Purchased Shares are at the time covered by such right.

          (b)  In the event of any of the following transactions (a "Corporate
Transaction"):

               (i)     a merger or acquisition in which the Corporation is not
     the surviving entity,

               (ii)   the sale, transfer or other disposition of all or
     substantially all of the assets of the Corporation or

               (iii)  any reverse merger in which the Corporation is the
     surviving entity but in which fifty percent (50%) or more of the
     Corporation's outstanding voting stock is transferred to holders different
     from those who held the stock immediately prior to such merger,

then the Corporation's First Refusal Right shall remain in full force and effect
and shall apply to the new capital stock or other property received in exchange
for the Purchased Shares in consummation of the Corporate Transaction, but only
to the extent the Purchased Shares are at the time covered by such right.

          4.7  Lapse.  The First Refusal Right under this Article IV shall
               -----
lapse and cease to have effect upon the earliest of (i) the first date on which
                                        --------
shares of the Corporation's Common Stock are held of record by more than five
hundred (500) persons, (ii) a determination is made by the Corporation's Board
of Directors that a public market exists for the outstanding shares of the
Corporation's Common Stock or (iii) a firm commitment underwritten public
offering, pursuant to an effective registration statement under the 1933 Act,
covering the offer and sale of the Corporation's Common Stock in the aggregate
of at least $5,000,000. However, the market stand-off provisions of paragraph
4.8 shall continue to remain in full force and effect following the lapse of the
First Refusal Right hereunder.

                                  pg. 4 of 10
<PAGE>

          4.8  Market Stand-Off.
               ----------------

          (a)  In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sales of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to any Purchased Shares without the prior written consent of the
Corporation or its underwriters. Such limitations shall be in effect for such
period of time from and after the effective date of such registration statement
as may be requested by the Corporation or such underwriters; provided, however,
                                                             --------
that in no event shall such period exceed one hundred-eighty (180) days. The
limitations of this paragraph 4.8 shall remain in effect for the two-year period
immediately following the effective date of the Corporation's initial public
offering and shall thereafter terminate and cease to have any force or effect.

          (b)  Owner shall be subject to the market stand-off provisions of this
paragraph 4.8 provided and only if the officers and directors of the Corporation
              --------------------
are also subject to similar arrangements.

          (c)  In the event of any stock dividend, stock split, recapitalization
or other change affecting the Corporation's outstanding Common Stock effected
without receipt of consideration, then any new, substituted or additional
securities distributed with respect to the Purchased Shares shall be immediately
subject to the provisions of this paragraph 4.8, to the same extent the
Purchased Shares are at such time covered by such provisions.

          (d)  In order to enforce the limitations of this paragraph 4.8, the
Corporation may impose stop-transfer instructions with respect to the Purchased
Shares until the end of the applicable stand-off period.

V.   MARITAL DISSOLUTION OR LEGAL SEPARATION
     ---------------------------------------

          5.1  Grant.  In connection with the dissolution of the Optionee's
               -----
marriage or the legal separation of the Optionee and the Optionee's spouse, the
Corporation shall have the right (the "Special Purchase Right "), exercisable at
any time during the thirty (30)-day period following the Corporation's receipt
of the required Dissolution Notice under paragraph 5.2, to purchase from the
Optionee's spouse, in accordance with the provisions of paragraph 5.3, all or
any portion of the Purchased Shares which would otherwise be awarded to such
spouse in settlement of any community property or other marital property rights
such spouse may have in such shares.

          5.2  Notice of Decree or Agreement.  The optionee shall promptly
               -----------------------------
provide the Secretary of the Corporation with written notice ("Dissolution
Notice") of (i) the entry of any judicial decree or order resolving the property
rights of the Optionee and the Optionee's spouse in connection with their
marital dissolution or legal separation (ii) the execution of any contract or
agreement relating to the distribution or division of such property rights. The
dissolution Notice shall be accompanied by a copy of the actual decree of
dissolution or settlement agreement between the Optionee and the Optionee's
spouse which provides for the award to the spouse of one or more Purchased
Shares in settlement of any community property or other marital property rights
such spouse may have in such shares.

          5.3  Exercise of Special Purchase Right.  The Special Purchase Right
               ----------------------------------
shall be exercisable by written notice ("Purchase Notice") delivered to the
Optionee and the Optionee's spouse within thirty (30) days after the
Corporation's receipt of the Dissolution Notice. The Purchase Notice shall
indicate the number of shares to be purchased, the date the purchase is to be
effected (such date to be not less than five (5) business days, nor more than
ten (10) business days, after the date of the Purchase Notice), and the fair
market value to be paid for such Purchased Shares. The Optionee (or the
Optionee's spouse, to the extent such spouse has physical possession of the
Purchased Shares) shall, prior to the close of business on the date specified
for the purchase, deliver to the Secretary of the Corporation the certificates
representing the shares to be purchased, each certificate to be properly
endorsed for transfer. The Corporation shall, concurrently with the receipt of
such stock certificates, pay to the Optionee's spouse (in cash or cash
equivalents) an amount equal to the fair market value specified for such shares
in the Purchase Notice.

                                  pg. 5 of 10
<PAGE>

          If the Optionee's spouse does not agree with the fair market value
specified for the shares in the Purchase Notice, then the spouse shall promptly
notify the Corporation in writing of such disagreement and the fair market value
of such shares shall thereupon be determined by an appraiser of recognized
standing selected by the Corporation and the spouse. If they cannot agree on an
appraiser within twenty (20) days after the date of the Purchase Notice, each
shall select an appraiser of recognized standing, and the two appraisers shall
designate a third appraiser of recognized standing whose appraisal shall be
determinative of such value.  The cost of the appraisal shall be shared equally
by the Corporation and The Optionee's spouse.  The closing shall then be held on
the fifth business day following the completion of such appraisal; provided,

                            STOCK OPTION AGREEMENT
                            ----------------------

          AGREEMENT made as of _________________, by and between Terrapin
Technologies, Inc., a Delaware corporation (hereinafter called "Company"), and
____________________ (hereinafter called "Optionee").

                                  WITNESSETH:
                                  ----------

RECITALS
--------

          A.  The Board of Directors of the Company has adopted the Company's
1988 Stock Option Plan (the "Plan") for the purpose of attracting and retaining
the services of selected key employees (including officers and directors), non-
employee members of the Board of Directors, and consultants and independent
contractors who contribute to the financial success of the Company or its
subsidiary corporations.  This Option is granted under the Plan.

          B.  Optionee is an individual who is to render valuable services to
the Company or its subsidiary corporations.

          C.  The granted option is intended to be a non-qualified stock option
which does not satisfy the requirements of Section 422 of the Internal Revenue
           ---
Code, as amended (the "Code").

          NOW, THEREFORE, it is hereby agreed as follows:

          1.  Grant of Option.  Subject to and upon the terms and conditions set
              ---------------
forth in this Agreement and in the Plan, there is hereby granted to Optionee, as
of __________ (the "Grant Date"), a stock option to purchase up to
__________________ (______) shares of the Company's Common Stock (the "Optioned
Shares") from time to time during the option term at the option price of
____________ (____) per share (the "Option Price").

          2.  Option Term.  This option shall have a maximum term of ten (10)
              -----------
years measured from the Grant Date and shall accordingly expire at the close of
business on ________________ (the "Expiration Date"), unless sooner terminated
in accordance with Paragraph 5 or 7(a) of this Agreement.

          3.  Option Nontransferable; Exception.  This option shall be
              ---------------------------------
transferable only by Optionee to an immediate member of Optionee's family, or
only by Optionee to a non-profit institution that currently employees the
Optionee.  With the exceptions provided in the preceding sentence, this option
shall be neither transferable nor assignable by Optionee other than by will or
by the laws of descent and distribution.  Unless this option is transferred
pursuant to the first sentence of this paragraph, this option may be exercised,
during Optionee's lifetime, only by Optionee.

                                      1.
<PAGE>

          4.  Dates of Exercise.  Optionee may, within the specified of this
              -----------------
option and pursuant to the provisions of this Agreement, purchase the Optioned
Shares in accordance with the following schedule:

              (i)   Twenty Percent (20%) of the Optioned Shares at any time
after the Grant Date.

              (ii)  The balance of the Optioned Shares in a series of sixty (60)
consecutive monthly installments, each equal to 1.3333 percent of the Optioned
Shares, with the first such installment to become exercisable one month from the
Grant Date, and each installment exercisable on the same day of each subsequent
month.

              Within the limitations provided in this Paragraph 4, Optionee may,
on any two occasions in each calendar year during the term of this option,
purchase any or all of the Optioned Shares for which this Option is at the time
exercisable.

          5.  Accelerated Termination of Option Term.  The option term specified
              --------------------------------------
in Paragraph 2 shall terminate (and this option shall cease to be exercisable)
prior to the Expiration Date should one of the following provisions become
applicable:

              (i)   Except as otherwise provided in subparagraphs (ii), (iii) or
(iv) below, should Optionee cease to be a Service Provider at any time during
the option term, then the Optionee shall have up to a three (3) month period
commencing with the date of such cessation of Service Provider status in which
to exercise this option for any or all of the Optioned Shares for which this
option is, in accordance with Paragraph 4, exercisable at the time of such
cessation of Service Provider status, but in no event shall this option be
exercisable at any time after the Expiration Date. Upon the expiration of such
three (3) month period or, if earlier, upon the Expiration Date, this option
shall terminate and cease to be outstanding.

              (ii)  Should Optionee die while this option is outstanding, then
the personal representative of the Optionee's estate or the person or persons to
whom the option is transferred pursuant to the Optionee's will or in accordance
with the law of descent and distribution or pursuant to this Stock Option
Agreement shall have the right to exercise this option provided and only if such
                                                       --------------------
exercise occurs prior to the earlier of (A) the expiration of the twelve (12)
                             -------
month period measured from the date of Optionee's death or (B) the Expiration
Date. During such period of limited exercisability, this option may be exercised
for any or all of the Optioned Shares for which this option is, in accordance
with Paragraph 4, exercisable at the time of the Optionee's cessation of Service
Provider status. Upon the expiration of such twelve (12) month period or, if
earlier, upon the Expiration Date, this option shall terminate and cease to be
outstanding.

              (iii) Should Optionee become permanently disabled, as defined in
Section 22(e)(3) of the Code, and cease by reason thereof to be a Service
Provider at any time during the option term, then the Optionee shall have a
period of twelve (12) months (commencing with the date of such cessation of
Service Provider status) in which to exercise this option for any or all of the
Optioned Shares for which this option is, in accordance with Paragraph 4,
exercisable at the time of such cessation of Service Provider status; provided,
                                                                      --------
however, that in no event shall this option be exercisable at any time after the
Expiration Date.  Upon the expiration of such limited period of exercisability
or, if earlier, upon the Expiration Date, this option shall terminate and cease
to be outstanding.

                                      2.
<PAGE>

              (iv)  Should the Optionee's status as a Service Provider be
terminated for misconduct (including, but not limited to, any act of dishonesty,
willful misconduct, fraud or embezzlement or any unauthorized disclosure or use
of confidential information or trade secrets) or should the Optionee make or
attempt to make any unauthorized use or disclosure of the confidential
information or trade secrets of the Company or any subsidiary corporation, then
in any such event this option shall terminate and cease to be exercisable thirty
(30) days after such termination of Service Provider status or such unauthorized
disclosure or use of confidential or secret information or attempt or threat.

              (v)   For purposes of this Paragraph 5 and for all other purposes
under this Agreement, the Optionee shall be deemed to be a Service Provider for
so long as the Optionee continues to render periodic services as an employee of
the Company or any subsidiary corporation, a member of the Board of Directors of
the Company, or any subsidiary corporation or as an independent contractor or
consultant to one or more of such entities. In applying the provisions of this
Agreement, a corporation shall be considered to be a subsidiary corporation of
the Company if it is a member of an unbroken chain of corporations beginning
with the Company, provided each such corporation in the chain (other than the
last corporation) owns, at the time of determination, stock possessing 50% or
more of the total combined voting power of all classes of stock in one of the
other corporations in such chain.

          6.  Change in Control of Company.  Notwithstanding the terms of
              -----------------------------
Paragraph 5 hereof to the contrary, in the event the termination of Optionee's
status as a Service Provider is caused by the request of a funding source of the
Company, and is not for cause, then the option to purchase the Optioned Shares
shall be deemed immediately vested and shall be exercisable at any time prior to
the Expiration Date.  This special provision shall be subject to the special
termination of option described in Paragraph 8 of this Agreement

          7.  Adjustment in Optioned Shares.
              -----------------------------

          (a) In the event any change is made to the Common Stock by reason of
any stock split, stock dividend, combination of shares, or other change
affecting the outstanding Common Stock as a class without receipt of
consideration, then appropriate adjustments will be made to (i) the total number
of Optioned Shares subject to this option, (ii) the number of Optioned Shares
for which this option may be exercised on each relevant date under paragraph 4
and (iii) the Option Price payable per share, in order to reflect such change
and thereby preclude a dilution or enlargement of benefits hereunder.

          (b) If the Company is the surviving entity in any merger or other
business combination, then this option, if outstanding under the Plan
immediately after such merger or other business combination, shall be
appropriately adjusted to apply and pertain to the number and class of
securities which would be issuable to the Optionee in respect of shares held by
the Optionee pursuant to this option in the consummation of such merger or
business combination if the option were exercised immediately prior to such
merger or business combination, and appropriate adjustments shall also be made
to the Option Price payable per share, provided the aggregate Option Price
payable hereunder shall remain the same.

          8.  Special Termination of Option.
              -----------------------------

          (a) In the event of one or more of the following transactions (a
"Corporate Transaction"):

              (i)   a merger or acquisition in which the Company is not the
surviving entity, except for a transaction the principal purpose of which is to
change the State of the Company's incorporation, or

                                      3.
<PAGE>

              (ii)  Any reverse merger in which the Company is the surviving
entity 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, the exercisability of this
option shall automatically be accelerated so that such option shall, during the
five (5) business day period immediately prior to the specified effective date
for the Corporate Transaction, become fully exercisable with respect to the
Optioned Shares and may be exercised for all or any portion of such shares;
provided, however, that the exercisability of the accelerated option as an
--------
incentive stock option under the federal tax laws shall remain subject to the
applicable limitations.  This option, to the extent not previously exercised,
shall terminate upon the consummation of such Corporate Transaction and cease to
be exercisable, unless it is expressly assumed by the successor corporation or
parent thereof.

          (b) This Agreement shall not in any way affect the right of the
Company to adjust, reclassify, reorganize or otherwise make changes in its
capital or business structure or to merge, consolidate, dissolve, liquidate or
sell or transfer all or any part of its business or assets.

          9.  Privilege of Stock Ownership.  The holder of this option shall not
              ----------------------------
have any of the rights of a shareholder with respect to the Optioned Shares
until such individual shall have exercised the option and paid the Option Price.

          10. Manner of Exercising Option.
              ---------------------------

          (a) In order to exercise this option with respect to all or any part
of the Optioned Shares for which this option is at the time exercisable,
Optionee (or in the case of exercise after Optionee's death, the Optionee's
executor, administrator, heir or legatee, as the case may be) must take the
following actions:

              (i)   Notify the Secretary of the Company, in accordance with
Paragraph 16 of this Agreement, of Optionee's desire to purchase Optioned
Shares.

              (ii)  Pay the aggregate Option Price for the purchased shares in
one or more of the following alternative forms:

                    (A) full payment, in cash or cash equivalents; or

                    (B) full payment in shares of Common Stock of the Company
held by the Optionee for the requisite period necessary to avoid a charge to the
Company's reported earnings and valued at Fair Market Value on the Exercise Date
(as such terms are defined below) in an amount equal to the Option Price; or

                    (C) full payment in a combination of shares of Common Stock
of the Company held by the Optionee for the requisite period necessary to avoid
a charge to the Company's reported earnings and valued at Fair Market Value on
the Exercise Date and cash or cash equivalents, equal in the aggregate to the
Option Price; or

                    (D) any other form which the Board of Directors of the
Company may, in its discretion, approve at the time of exercise in accordance
with the provisions of paragraph 16 of this Agreement;

                                      4.
<PAGE>

              (iii) Furnish to the Company appropriate documentation that the
person or persons exercising the option, if other than Optionee, have the right
to exercise this option.

              (iv)  Execute whatever documents are reasonably deemed necessary
by the Board of Directors of the Company in order for the Company and the
Optionee to comply with the then current laws and regulations regarding the
issue of securities by the Company. Optionee must also execute the Stock
Purchase Agreement in the form attached to this Agreement.

          (b) For purposes of this Paragraph 10, the Fair Market Value of a
share of Common Stock shall be determined in accordance with subparagraphs (i)
through (iii) below, and the Exercise Date shall be the first date on which
there shall have been delivered to the Company both (I) the notice of Optionee's
desire to exercise and (II) the payment of the Option Price for the purchased
shares.

              (i)   If the Common Stock is not on the Exercise Date listed or
admitted to trading on any stock exchange, but is traded in the over-the-counter
market, the Fair Market Value shall be the mean between the highest bid and
lowest asked prices (or if such information is available, the closing selling
price) of one share of Common Stock on the Exercise Date in the over-the-counter
market, as such prices are reported by the National Association of Securities
Dealers through its NASDAQ system or any successor system. If there are no
reported bid and asked prices (or closing selling price) for the Common Stock on
the Exercise Date, then the mean between the highest bid and the lowest asked
prices (or closing selling price) on the last preceding date for which such
quotations exist shall be determinative of Fair Market Value.

              (ii)  If the Common Stock is on the Exercise Date listed or
admitted to trading on any stock exchange, then the Fair Market Value shall be
the closing selling price of one share of Common Stock on the Exercise Date on
the stock exchange determined by the Board of Directors of the Company to be the
primary market for the Common Stock, as such price is officially quoted in the
composite tape of transactions on such exchange. If there is no reported sale of
Common Stock on such exchange on the Exercise Date, then the Fair Market Value
shall be the closing selling price on the exchange on the last preceding date
for which such quotation exists.

              (iii) If the Common Stock is on the Exercise Date neither listed
or admitted to trading on any stock exchange nor traded in the over-the-counter
market, then the Fair Market Value shall be determined by the Board of Directors
of the Company after taking into account such factors as they shall deem
appropriate.

          (c) This option shall be deemed to have been exercised with respect to
the number of Optioned Shares specified in the notice of Optionee's desire to
purchase Optioned Shares at such time as said notice shall have been received by
the Company.  Payment of the Option Price shall immediately become due and shall
accompany the notice.  As soon thereafter as practical, the Company shall mail
or deliver to Optionee or to the other person or persons exercising this option
a certificate or certificates representing the shares so purchased and paid for,
with the appropriate legends affixed thereto.

          (d) In no event may this option be exercised for less than one hundred
shares or any fractional shares.

          11. RIGHTS OF FIRST REFUSAL.  THE OPTIONEE HEREBY AGREES THAT ALL
              -----------------------
OPTIONED SHARES ACQUIRED UPON THE EXERCISE OF THIS OPTION SHALL BE SUBJECT TO
CERTAIN RIGHTS OF THE COMPANY AND ITS ASSIGNS TO REPURCHASE SUCH SHARES IN
ACCORDANCE WITH THE TERMS AND CONDITIONS SPECIFIED IN THE "PURCHASE AGREEMENT,"
A COPY OF WHICH IS ATTACHED TO THIS AGREEMENT.

                                      5.
<PAGE>

          12. Compliance with Laws and Regulations.
              ------------------------------------

          (a) The exercise of this option and the issuance of Optioned Shares
upon such exercise shall be subject to compliance by the Company and the
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange on which shares of the Company's
Common Stock may be listed at the time of such exercise and issuance.

          (b) In connection with the exercise of this option, Optionee shall
execute and deliver to the Company such representations in writing as may be
requested by the Company in order for it to comply with the applicable
requirements of federal and state securities laws.

          (c) Optionee understands that, when issued, with regard to the
purchased shares:

              (i)   Exemption from Registration. The purchased shares will not
                    ---------------------------
have registered under the Securities Act of 1933, as amended (the "1933 Act")
and will be issued to Optionee in reliance upon the exemption from such
registration provided by Rule 701 of the Securities and Exchange Commission for
stock issuances under compensatory benefit plans.

              (ii)  Restricted Securities. Optionee will confirm that Optionee
                    ---------------------
has been informed that the purchased shares are restricted securities under the
1933 Act and may not be resold or transferred unless the purchased shares are
first registered under the Federal securities laws or unless an exemption from
such registration is available. Accordingly, Optionee will acknowledge that
Optionee is prepared to hold the purchased shares for an indefinite period and
that Optionee is aware that Rule 144 of the Securities and Exchange Commission
issued under the 1933 Act is not presently available to exempt the sale of the
purchased shares from the registration requirements of the 1933 Act. Upon the
expiration of the ninety (90)-day period immediately following the date on which
the Corporation first becomes subject to the reporting requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), the purchased
shares may be sold (without registration) pursuant to the applicable
requirements of Rule 144. If Optionee is at the time of such sale an affiliate
of the Corporation for purposes of Rule 144 or was an affiliate during the
preceding three (3) months, then the sale must comply with all the requirements
of Rule 144 (including the volume limitation on the number of shares sold, the
broker/market maker sale requirement and the requisite notice to the Securities
and Exchange Commission); however, the two-year holding period requirement of
the Rule will not be applicable. If Optionee is not at the time of the sale an
affiliate of the Corporation nor was Optionee an affiliate during the preceding
three (3) months, then none of the requirements of Rule 144 (other than the
broker/market maker sale requirement for purchased shares held for less than
three (3) years following payment in cash of the Option Price therefor) will be
applicable to the sale. Should the Corporation not become subject to the
reporting requirements of the Exchange Act, then Optionee may, provided he/she
is neither at the time an affiliate of the Corporation nor was an affiliate
during the preceding three (3) months, sell the purchased shares (without
registration) pursuant to paragraph (k) of Rule 144 after the purchased shares
have been held for a period of three (3) years following the payment in cash of
the Option Price for such shares.

          (d) Restrictive Legends.  In order to reflect the restrictions on
              -------------------
disposition of the purchased shares, the stock certificates for the purchased
shares will be endorsed with restrictive legends, including one or both of the
following legends:

              (i)   "The shares represented by this certificate have not been
registered under the Securities Act of 1933.  The shares may not be sold or
offered for sale in the absence of (a) an effective registration statement for
the shares under such Act, (b) a "no action" letter of the Securities and
Exchange Commission with respect to such sale or offer, or (c) satisfactory
assurances to the Company that registration under such Act is not required with
respect to such sale or offer."

                                      6.
<PAGE>

              (ii)  "It is unlawful to consummate a sale or transfer of this
security, or any interest therein, or to receive any consideration therefor,
without the prior written consent of the Commissioner of Corporations of the
State of California, except as permitted in the Commissioner's Rules."

          (e) Receipt of Commissioner Rules.  Optionee will receive a copy of
              -----------------------------
Section 260.141.11 of the Rules of the California Corporations Commissioner upon
the grant of this option, a copy of which is attached to this Agreement.

          13. Successors and Assigns.  Except to the extent otherwise provided
              ----------------------
in paragraph 3, the provisions of this Agreement shall inure to the benefit of,
and be binding upon, the successors, administrators, heirs, legal
representatives and assigns of Optionee and the successors and assigns of the
Company.

          14. Liability of Company.  The inability of the Company to obtain
              --------------------
approval from any regulatory body having authority deemed by the Company to be
necessary to the lawful issuance and sale of any Common Stock pursuant to this
option shall relieve the Company of any liability with respect to the non-
issuance or sale of the Common Stock as to which such approval shall not have
been obtained.  The Company, however, shall use its best efforts to obtain all
such approvals.

          15. No Employment or Service Contract.  Nothing in this Agreement
              ---------------------------------
shall confer upon the Optionee any right to continue in the employ of the
Company (or any subsidiary corporation of the Company employing or retaining
Optionee) for any period of time or interfere with or restrict in any way the
rights of the Company (or any subsidiary corporation of the Company employing or
retaining Optionee) or the Optionee, which rights are hereby expressly reserved
by each, to terminate the Service Provider status of Optionee at any time for
any reason whatsoever, with or without cause.

          16. Notices.  Any notice required to be given or delivered to the
              -------
Company under the terms of this Agreement shall be in writing and addressed to
the Company in care of the Company's President, with a copy to the Company's
Secretary, at its corporate offices.  Any notice required to be given or
delivered to Optionee shall be in writing and addressed to Optionee at the
address indicated below Optionee's signature line on this Agreement.  All
notices shall be deemed to have been given or delivered upon personal delivery
or upon deposit in the U.S. Mail, postage prepaid and properly addressed to the
party to be notified.

          17. Withholding.  Optionee hereby agrees to make appropriate
              -----------
arrangements with the Company or subsidiary corporation employing Optionee (if
any) for the satisfaction of any federal, state or local income tax withholding
requirements and federal social security employee tax requirements applicable to
the exercise of this option.

          18. Construction. All decisions of the Board of Directors of the
              ------------
Company with respect to any question or issue arising under this Agreement shall
be conclusive and binding upon all persons having an interest in this option.

          19. Governing Law.  The interpretation, performance, and enforcement
              -------------
of this Agreement shall be governed by the laws of the State of California.

          20. Counterparts.  This Agreement may be executed in counterparts,
              ------------
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

                                      7.

          IN WITNESS WHEREOF, the Company has caused this Agreement to be
