                              MEGATEST CORPORATION
                    EXECUTIVE OFFICER STOCK OPTION AGREEMENT



         Megatest Corporation, a Delaware Corporation (the "Company"), has
granted to:

_______________________________ (the "Optionee"), an option (the "Option") to
purchase a total of ________________(_______) shares of Common Stock (the
"Shares"), at the price determined as provided herein, and in all respects
subject to the terms, definitions and provisions of the 1990 Stock Option Plan
(the "Plan") adopted by the Company, which is incorporated herein by reference.
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings herein.

         1.      Nature of the Option.  This Option is intended to qualify as
an Incentive Stock Option as defined in Section 422 of the Code.

         2.      Exercise Price.  The exercise price is _______ for each share
of Common Stock, which price is not less than the fair market value per share
of the Common Stock on the date of grant.

         3.      Exercise of Option. This Option shall be exercisable during
its term in accordance with the provisions of Section 9 of the Plan as follows:

                 (i)      Right to Exercise.

                                  (a)      Subject to subsections 3(i)(b), (c)
and (d) and Section 3(ii) below, this Option shall be exercisable according to
the attached schedule of "INDIVIDUAL RECORD OF STOCK OPTIONS."

                                  (b)      This Option may not be exercised for
a fraction of a share.

                                  (c)      In the event of the Optionee's
death, disability or other termination of employment or consulting
relationship, the exercisability of the Option is governed by Section 7, 8, and
9 below.

                                  (d)      In no event may this Option be
exercised after the date of expiration of the term of this Option as set forth
in Section 11 below.

                 (ii)     Accelerated Vesting Upon Change of Control.

                                  (a)      Notwithstanding any provision of the
Plan or Section 3(i) or Section 7 of this Agreement to the contrary, if within
12 months following a Change of Control the Optionee is terminated other than
for Just Cause, or the Optionee resigns voluntarily for Good Reason, this
Option shall upon such termination or resignation become fully vested and
exercisable as to all of the Shares, unless, in connection with such Change of
Control, the Board determines, based upon its receipt of a written opinion of
the Company's independent public accountants, that the provisions of this
Section 3(ii) would preclude accounting for any proposed Business Combination
of the Company as a "pooling of interests" and a condition to the closing of
such Business Combination is that it be so accounted for as a pooling of
interests, in which case this Section 3(ii) shall be of no force or effect.

                                  (b)      For purposes of this Section 3(ii),
the following definitions shall apply:

                                        (1)     "Business Combination" means a
consolidation or merger as a result of which the holders of the Company's
voting stock prior thereto hold less than 50% of the voting stock of the
surviving or successor corporation (including any parent corporation) or entity
(the "Successor"), or a sale of all or substantially all of the Company's
assets.

                                        (2)     "Change of Control" of the
Company means and includes any of the following occurrences:

                                        (A)      A Business Combination which
has been approved by the requisite vote of the Company's stockholders; or

                                        (B)      Any "person" (as such term is
used in Section 13(d) and 14(d) of the Securities Exchange Act of 1934, as
amended) becomes the "beneficial owner" as defined in Rule 13(d)-3 of the
general rules and regulations under said Act, directly or indirectly, of
securities of the Company representing fifty percent (50%) or more of the total
voting power represented by the Company's then outstanding voting securities;
or

                                        (C)      A change in the composition of
the Board of Directors of the Company over a two-year period, as a result of
which fewer than a majority of





                                      -2-

the Directors are Incumbent Directors.  "Incumbent Directors" shall mean
Directors who either (i) are Directors of the Company as of the date hereof, or
(ii) are elected, or nominated for election, to the Board of Directors of the
Company with the affirmative votes of at least a majority of the Incumbent
Directors at the time of such election or nomination (but not including an
individual whose election or nomination is in connection with an actual or
threatened proxy contest relating to the election of Directors to the Company).

                                        For purposes hereof, the Board of
Directors may, by resolution, clarify the date as of which a Change of Control
shall be deemed to have occurred.

                                        (3)     "Compensation" of the Optionee
means and includes all wages, salary, bonus, and incentive compensation paid by
the Company or the Successor as consideration for the Optionee's service that
are includable in the gross income of the Optionee receiving the same for
federal income tax purposes, but excluding income arising from the exercise of
stock options.

                                        (4)     "Just Cause" means the
termination of employment of the Optionee shall have taken place as a result of
(A) an act or acts of dishonesty undertaken by the Optionee and intended to
result in substantial gain or personal enrichment of the Optionee at the
expense of the Company or the Successor; (B) persistent failure by the Optionee
to perform the duties and obligations of the Optionee's employment, which are
demonstrably willful and deliberate on the Optionee's part and which are not
remedied in a reasonable period of time after receipt of written notice from
the Company or the Successor; or (C) the conviction of the Optionee of a felony
or the entry by the Optionee of a plea of no contest.

                                        (5)     "Good Reason" means and
includes any of the following occurrences:

                                                (A)      The Successor reduces
the Optionee's Compensation as in effect immediately prior to the Change of
Control, unless such reduction amounts to less than ten percent (10%) of such
Compensation and is pursuant to a proportionate reduction of the Compensation
of all executive officers of the Successor.

                                                (B)       Without the Optionee's
express written consent, the Successor requires the Optionee to change the
location of the Optionee's job or office, so that the Optionee will be based at
a location more than 35 miles from the location of the Optionee's job or office
immediately prior to the Change of Control.

                                                (C)      The cost of benefits
provided by the Successor, under plans, arrangements, policies and procedures,
taken as a whole, decreases by 25% or more of the cost provided by the Company
immediately prior to the Change of Control, or the cost of such benefits to the 
Optionee increases by 25% or more of the Optionee's cost immediately prior





                                      -3-
   4

to the Change of Control; provided, however, that if such decrease or increase
results from the good faith exercise of business judgment by the Successor or
in response to changes in federal or state law, and is applicable to all
executive officers of the Successor, such decrease or increase shall not
constitute a Good Reason for resignation.

                                                (D)      Without the Optionee's
express written consent, the Optionee incurs a significant reduction in the
Optionee's responsibilities or duties.

                                                (E)      The Successor fails 
or refuses to assume the Company's obligations hereunder.


                          (iii)   Method of Exercise.  This Option shall be
exercisable by written notice which shall state the election to exercise the
Option, the number of Shares in respect of which the Option is being exercised,
and such other representations and agreements as to the holder's investment
intent with respect to such shares of Common Stock as may be required by the
Company pursuant to the provisions of the Plan.  Such written notice shall be
signed by the Optionee and shall be delivered in person or by certified mail to
the Secretary of the Company.  The written notice shall be accompanied by
payment of the exercise price.  This Option shall be deemed exercised upon
receipt by the Company of such written notice accompanied by the exercise
price.

         No shares will be issued pursuant to the exercise of an Option unless
such issuance and such exercise shall comply with all relevant provisions of
law and the requirements of any stock exchange upon which the shares may then
be listed.  Assuming such compliance, for income tax purposes the Shares shall
be considered transferred to the Optionee on the date on which the Option is
exercised with respect to such Shares."


         4.      Optionee's Representations.  In the event the Shares
purchasable pursuant to the exercise of this Option have not been registered
under the Securities Act of 1933, as amended, at the time this Option is
exercised, Optionee shall, concurrently with the exercise of all or any portion
of this Option, deliver to the Company his Investment Representation Statement
in the form attached hereto as Exhibit B, and shall read the applicable rules
of the Commissioner of Corporations attached to such Investment Representation
Statement.

         5.      Method of Payment.  Payment of the exercise price shall be by:

                 (i)      cash;

                 (ii)     check; or





                                      -4-
   5

                 (iii)    surrender of other shares of Common Stock of the
Company which (A) either have been owned by the Optionee for more than six (6)
months on the date of surrender or were not acquired, directly or indirectly,
from the Company and (B) have a fair market value on the date of surrender
equal to the exercise price of the Shares as to which the Option is being
exercised;

or any combination thereof, at the election of the Board.

         6.      Restrictions on Exercise.  This Option may not be exercised
until such time as the Plan has been approved by the shareholders of the
Company, or if the issuance of such Shares upon such exercise or the method of
payment of consideration for such shares would constitute a violation of any
applicable federal or state securities or other law or regulation, including
any rule under Part 207 of Title 12 of the Code of Federal Regulations
("Regulation G") as promulgated by the Federal Reserve Board.  As a condition
to the exercise of this Option, the Company may require Optionee to make any
representation and warranty to the Company as may be required by any applicable
law or regulation.

         7.      Termination of Status as an Employee.  In the event of
termination of Optionee's Continuous Status as an Employee, he may, but only
within thirty days after the date of such termination (but in no event later
than the date of expiration of the term of this Option as set forth in Section
11 below), exercise this Option to the extent that he was entitled to exercise
it at the date of such termination.  To the extent that he was not entitled to
exercise this Option at the date of such termination, or if he does not
exercise this Option within the time specified herein, the Option shall
terminate.

         8.      Disability of Optionee.  Notwithstanding the provisions of
Section 7 above, in the event of termination of Optionee's Continuous Status as
an Employee as a result of his total and permanent disability (as defined in
Section 22(e)(3) of the Code), he may, but only within six months from the date
of termination of employment (but in no event later than the date of expiration
of the term of this Option as set forth in Section 11 below), exercise his
Option to the extent he was entitled to exercise it at the date of such
termination.  To the extent that he was not entitled to exercise the Option at
the date of termination, or if he does not exercise such Option (which he was
entitled to exercise) within the time specified herein, the Option shall
terminate.

         9.      Death of Optionee.  In the event of the death of Optionee:

                 (i)      during the term of this Option and while an Employee
of the Company and having been in Continuous Status as an Employee since the
date of grant of the Option, the Option may be exercised, at any time within
one year following the date of death (but in no event later than the date of
expiration of the term of this Option as set forth in Section 11 below), by
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
would have accrued had the





                                      -5-
   6

Optionee continued living and remained in Continuous Status as an Employee one
year after the date of death; or

                 (ii)     within thirty days after the termination of
Optionee's Continuous Status as an Employee, the Option may be exercised, at
any time within one year following the date of death (but in no event later
than the date of expiration of the term of this Option as set forth in Section
11 below), by Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, but only to the extent of the
right to exercise that had accrued at the date of termination.

    10.  Non-Transferability of Option.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by him.  The terms of
this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

    11.  Term of Option.  This Option may not be exercised more than ten (10)
years (five years if Optionee owns, immediately before this Option is granted,
stock representing more than 10 percent of the total combined voting power of
all classes of stock of the Company or of any Parent or Subsidiary) from the
date of grant of this Option, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.

    12.  Early Disposition of Stock.  Optionee understands that if he disposes
of any Shares received under this Option within two (2) years after the date of
this Agreement or within one (1) year after such Shares were transferred to
him, he will be treated for federal income tax purposes as having received
ordinary income at the time of such disposition in an amount generally measured
by the difference between the price paid for the Shares and the lower of the
fair market value of the Shares at the date of the exercise or the fair market
value of the Shares at the date of disposition.  The amount of such ordinary
income may be measured differently if Optionee is an officer, director or 10%
shareholder of the Company, or if the Shares were subject to a substantial risk
of forfeiture at the time they were transferred to Optionee.  Optionee hereby
agrees to notify the Company in writing within 30 days after the date of any
such disposition.  Optionee understands that if he disposes of such Shares at
any time after the expiration of such two-year and one-year holding periods,
any gain on such sale will be taxed as long-term capital gain.
