                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE

     The Registrant hereby incorporates by reference in this Registration
Statement the following documents:

          1. The Company's Annual Report on Form 10-K for the fiscal year ended
     December 31, 1998, filed pursuant to Section 13(a) of the Securities
     Exchange Act of 1934, as amended (the "Exchange Act").

          2. The Company's Quarterly Report on Form 10-Q for the quarter ended
     March 31, 1999, filed pursuant to Section 13(a) of the Exchange Act.

          3. The description of the Company's Common Stock as set forth in the
     Registration Statement filed by the Company on Form 8-A on March 18, 1988
     pursuant to Section 12 of the Exchange Act, including any amendment or

          4. All documents subsequently filed by the Company pursuant to
     Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, after the date of
     this registration statement and prior to the filing of a post-effective
     amendment which indicates that all securities offered hereby have been sold
     or which deregisters all securities remaining unsold, shall be deemed to be
     incorporated by reference in this registration statement and to be a part
     hereof from the date of filing of such documents.

ITEM 4. DESCRIPTION OF SECURITIES

     Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Registrant's Certificate of Incorporation and By-laws require the
Registrant to indemnify officers and directors of the Registrant to the fullest
extent permitted by the Delaware General Corporation Law. Article EIGHTH of the
Registrant's Certificate of Incorporation includes a provision that eliminates
the personal liability of its directors for monetary damage for breach of their
fiduciary duty as a director, to the extent allowed under Delaware law. Article
VII of the Registrant's By-Laws provide, among other things, that (i) the
Registrant is required to indemnify its directors and officers and persons
serving in such capacities in other business enterprises at the Registrant's
request, (ii) the Registrant is required to advance expenses, as incurred, to
its directors and officers in connection with defending a proceeding, provided
that such individual delivers an undertaking to the Registrant that he or she
will repay all amounts advanced in the event it is ultimately determined that
such individual is not entitled to be indemnified, (iii) the rights conferred in
the By-Laws are not exclusive and (iv) the Registrant may not retroactively
amend the By-Law provisions in a way that is adverse to such directors and
officers.

     The Registrant's policy is to enter into indemnification agreements with
each of its directors and officers that provide the maximum indemnity allowed to
directors and officers by Section 145 of the Delaware General Corporation Law
and the By-Laws, as well as certain additional procedural protections.

     Section 145 of the Delaware General Corporation Law provides for the
indemnification of officers, directors and other corporate agents in terms
sufficiently broad to indemnify such individuals, under certain circumstances,
for liabilities (including reimbursement of expenses incurred) arising under the
Securities Act of 1933, as amended (the "Securities Act"). The Registrant
intends to enter into indemnification agreements to such effect with its
officers and directors.

ITEM 9. UNDERTAKINGS

     (a) Rule 415 offering

     The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement to include
     any material information with respect to the plan of distribution not
     previously disclosed in the registration statement or any material change
     to such information in the registration statement;

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) Filing incorporating subsequent Exchange Act documents by reference

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (c) Request for acceleration of effective date or filing of registration
statement on Form S-8

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

authorized, in the City of San Jose, State of California, on June 22, 1999.

        RE:    REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

        We have examined the Registration Statement on Form S-8 to be filed by
you with the Securities and Exchange Commission on or about June 29, 1999 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of an aggregate of 2,726,606 shares of your
Common Stock, of which 2,500,000 shares are reserved for issuance under the 1996
Stock Option Plan, 200,000 shares are reserved for issuance under the 1987
Employee Stock Purchase Plan and 26,606 shares are reserved for issuance under
the 1998 Boulder Creek Engineering Stock Option Plan. Such shares of Common
Stock are referred to herein as the "Shares," and the plans are referred to
herein as the "Plans." As your legal counsel, we have examined the proceedings
taken and are familiar with the proceedings proposed to be taken by you in
connection with the issuance and sale of the Shares pursuant to the Plans.

        It is our opinion that the Shares, as or when issued and sold in the
manner described in the Registration Statement and sold in the manner referred
to in the Plans and pursuant to the agreement which accompanies each grant under
the Plans, are or will be legally and validly issued, fully-paid and
non-assessable.

        We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the

Exchange Program, the unpurchased Shares which were subject thereto shall become
available for future grant or sale under the Plan (unless the Plan has
terminated). However, Shares that have actually been issued under the Plan, upon
exercise of either an Option or Stock Purchase Right, shall not be returned to
the Plan and shall not become available for future distribution under the Plan,
except that if Shares of Restricted Stock are repurchased by the Company at
their original purchase price, such Shares shall become available for future
grant under the Plan.

4.      Administration of the Plan.

        (a)    Administrator. The Plan shall be administered by the Board or a

with Applicable Laws.

        (b)    Powers of the Administrator. Subject to the provisions of the
Plan and, in the case of a Committee, the specific duties delegated by the Board
to such Committee, and subject to the approval of any relevant authorities, the
Administrator shall have the authority in its discretion:

               (i) to determine the Fair Market Value;

               (ii) to select the Service Providers to whom Options and Stock
Purchase Rights may from time to time be granted hereunder;

               (iii) to determine the number of Shares to be covered by each
such award granted hereunder;

               (iv) to approve forms of agreement for use under the Plan;

               (v) to determine the terms and conditions of any Option or Stock
Purchase Right granted hereunder. Such terms and conditions include, but are not
limited to, the exercise price, the time or times when Options or Stock Purchase
Rights may be exercised (which may be based on performance criteria), any
vesting acceleration or waiver of forfeiture restrictions, and any restriction
or limitation regarding any Option or Stock Purchase Right or the Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

               (vi) to determine whether and under what circumstances an Option
may be settled in cash under Subsection 9(e) instead of Common Stock;

               (vii) to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option has declined since the date the Option was granted;

               (viii) to initiate an Option Exchange Program;

               (ix) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to subplans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

               (x) to allow Optionees to satisfy withholding tax obligations by
electing to have the Company withhold from the Shares to be issued upon exercise
of an Option or Stock Purchase Right that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market Value of the
Shares to be





                                       4
<PAGE>   5

withheld shall be determined on the date that the amount of tax to be withheld
is to be determined. All elections by Optionees to have Shares withheld for this
purpose shall be made in such form and under such conditions as the
Administrator may deem necessary or advisable; and

               (xi) to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

        (c)    Effect of Administrator's Decision. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees.

5.      Eligibility.

        (a) Nonstatutory Stock Options and Stock Purchase Rights may be granted
to Service Providers. Incentive Stock Options may be granted only to Employees.

        (b) Each Option shall be designated in the Option Agreement as either an
Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding
such designation, to the extent that the aggregate Fair Market Value of the
Shares with respect to which Incentive Stock Options are exercisable for the
first time by the Optionee during any calendar year (under all plans of the
Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be
treated as Nonstatutory Stock Options. For purposes of this Section 5(b),
Incentive Stock Options shall be taken into account in the order in which they
were granted. The Fair Market Value of the Shares shall be determined as of the
time the Option with respect to such Shares is granted.

        (c) Neither the Plan nor any Option or Stock Purchase Right shall confer
upon any Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall it interfere in
any way with his or her right or the Company's right to terminate such
relationship at any time, with or without cause.

6.      Term of Plan. The Plan shall become effective upon its adoption by the
Board. It shall continue in effect for a term of ten (10) years unless sooner
terminated under Section 14 of the Plan.

7.      Term of Option. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.

8.      Option Exercise Price and Consideration.

        (a) The per Share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

               (i)   In the case of an Incentive Stock Option

                     (A) granted to an Employee who, at the time of grant of
such Option, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
exercise price shall be no less than 110% of the Fair Market Value per Share on
the date of grant.

                     (B) granted to any other Employee, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

               (ii)  In the case of a Nonstatutory Stock Option

                     (A) granted to a Service Provider who, at the time of grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the exercise price shall be no less than 110% of the Fair Market Value per Share
on the date of grant.

                     (B) granted to any other Service Provider, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share on
the date of grant.

               (iii) Notwithstanding the foregoing, Options may be granted with
a per Share exercise price other than as required above pursuant to a merger or
other corporate transaction.

        (b)    The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with
the Plan, or (6) any combination of the foregoing methods of payment. In making
its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

9.      Exercise of Option.

        (a)    Procedure for Exercise; Rights as a Stockholder. Any Option
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement. Except in the case of Options granted to Officers,
Directors and Consultants, Options shall become exercisable at a rate of no less
than 25% per year over four (4) years from the date the Options are granted.
Unless the Administrator provides otherwise, vesting of Options granted
hereunder shall be tolled during any unpaid leave of absence. An Option may not
be exercised for a fraction of a Share.

        An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

        Exercise of an Option in any manner shall result in a decrease in the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

        (b)    Termination of Relationship as a Service Provider. If an Optionee
ceases to be a Service Provider, such Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement (of at least
thirty (30) days) to the extent that the Option is vested on the date of
termination (but in no event later than the expiration of the term of the Option
as set forth in the Option Agreement). In the absence of a specified time in the
Option Agreement, the Option shall remain exercisable for three (3) months
following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified by
the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

        (c)    Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
(of at least six (6) months to the extent the Option is vested on the date of
termination (but in no event later than the





                                       7
<PAGE>   8

expiration of the term of such Option as set forth in the Option Agreement). In
the absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination. If, on
the date of termination, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall revert to
the Plan. If, after termination, the Optionee does not exercise his or her
Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

        (d)    Death of Optionee. If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement (of at least six (6) months) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance. In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to the
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan. If the Option is not so exercised within the
time specified herein, the Option shall terminate, and the Shares covered by
such option shall revert to the Plan.

        (e)    Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted, based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

10.     Nontransferability of Options and Stock Purchase Rights. The Options
and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

11.     Stock Purchase Rights.

        (a) Rights to Purchase. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be
entitled to purchase, the price to be paid, and the time within which such
person must accept such offer. The terms of the offer shall comply in all
respects with Section 260.140.42 of Title 10 of the California Code of
Regulations. The offer shall be accepted by execution of a Restricted Stock
Purchase Agreement in the form determined by the Administrator.

        (b) Repurchase Option. Unless the Administrator determines otherwise,
the Restricted Stock Purchase Agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with





                                       8
<PAGE>   9

the Company for any reason (including death or disability). The purchase price
for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall
be the original price paid by the purchaser and may be paid by cancellation of
any indebtedness of the purchaser to the Company. The repurchase option shall
lapse at such rate as the Administrator may determine. Except with respect to
Shares purchased by Officers, Directors and Consultants, the repurchase option
shall in no case lapse at a rate of less than 20% per year over five (5) years
from the date of purchase.

        (c)    Other Provisions. The Restricted Stock Purchase Agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

        (d)    Rights as a Stockholder. Once the Stock Purchase Right is
exercised, the purchaser shall have rights equivalent to those of a stockholder
and shall be a stockholder when his or her purchase is entered upon the records
of the duly authorized transfer agent of the Company. No adjustment shall be
made for a dividend or other right for which the record date is prior to the
date the Stock Purchase Right is exercised, except as provided in Section 12 of
the Plan.

12.     Adjustments upon Changes in Capitalization, Merger or Asset Sale.

        (a)    Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company. The conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration". Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option or Stock Purchase Right.

        (b)    Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option or Stock Purchase Right until
fifteen (15) days prior to such transaction as to all of the





                                       9
<PAGE>   10

Optioned Stock covered thereby, including Shares as to which the Option or Stock
Purchase Right would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse
as to all such Shares, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated. To the extent is has not been
previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

        (c)    Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the Option or
Stock Purchase Right, the Optionee shall fully vest in and have the right to
exercise the Option or Stock Purchase Right as to all of the Optioned Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
an Option or Stock Purchase Right becomes fully vested and exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option or Stock Purchase
Right shall terminate upon the expiration of such period. For the purposes of
this paragraph, the Option or Stock Purchase Right shall be considered assumed
if, following the merger or sale of assets, the option or right confers the
right to purchase or receive, for each Share of Optioned Stock subject to the
Option or Stock Purchase Right immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of
the majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option or Stock Purchase Right, for each Share
of Optioned Stock subject to the Option or Stock Purchase Right, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

13.     Time of Granting Options and Stock Purchase Rights. The date of grant of
an Option or Stock Purchase Right shall, for all purposes, be the date on which
the Administrator makes the determination granting such Option or Stock Purchase
Right, or such other date as is determined by the Administrator. Notice of the
determination shall be given to each Service Provider to whom an Option or Stock
Purchase Right is so granted within a reasonable time after the date of such
grant.

14.     Amendment and Termination of the Plan.

        (a)    Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

        (b)    Stockholder Approval. The Board shall obtain stockholder approval
of any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.

        (c)    Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

15.     Conditions Upon Issuance of Shares.

        (a)    Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

        (b)    Investment Representations. As a condition to the exercise of an
Option, the Administrator may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

16.     Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

17.     Reservation of Shares. The Company, during the term of this Plan, shall
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

18.       Stockholder Approval. The Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months after the date the Plan is
adopted. Such stockholder approval shall be obtained in the degree and manner
required under Applicable Laws.

19.     Information to Optionees and Purchasers. The Company shall provide to
each Optionee and to each individual who acquires Shares pursuant to the Plan,
not less frequently than annually during the period such Optionee or purchaser
has one or more Options or Stock Purchase Rights outstanding, and, in the case
of an individual who acquires Shares pursuant to the Plan, during the period
such individual owns such Shares, copies of annual financial statements. The
Company shall not be required to provide such statements to key employees whose
duties in connection with the Company assure their access to equivalent
information.

        Term/Expiration Date           _________________________________________

        Exercise and Vesting Schedule

        So long as Optionee is a Service Provider, this Option shall be

vesting schedule:





                                       1
<PAGE>   14

        Twenty-four percent (24%) of the Shares subject to the Option shall vest
on the one year anniversary of the Vesting Commencement Date, and 2% of the
Optioned Stock shall be released on the first day of each calendar month
thereafter such that 100% of the Optioned Stock shall be exercisable after 50
months.

        Termination Period

        This Option may be exercised, to the extent it is then vested, for three
months after Optionee ceases to be a Service Provider. Upon death or Disability
of the Optionee, this Option may be exercised, to the extent it is then vested,
for one year after Optionee ceases to be a Service Provider. In no event shall
this Option be exercised later than the Term/Expiration Date as provided above.

II.     AGREEMENT

        1.     Grant of Option. The Plan Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant (the "Optionee"), an option
(the "Option") to purchase the number of Shares set forth in the Notice of
Grant, at the exercise price per Share set forth in the Notice of Grant (the
"Exercise Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference. Subject to Section 14(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and this Option
Agreement, the terms and conditions of the Plan shall prevail.

        If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option as
defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds
the $100,000 rule of the Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

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

               (a)    Right to Exercise

                      (i) Subject to Subsections 2(a)(ii) and 2(a)(iii) below,
this Option shall be exercisable cumulatively according to the vesting schedule
set forth in the Notice of Grant. Alternatively, at the election of the
Optionee, this option may be exercised in whole or in part at any time as to
Shares which have not yet vested. For purposes of this Stock Option Agreement,
Shares subject to the Option shall vest based on continued employment of
Optionee with the Company. Vested Shares shall not be subject to the Company's
repurchase right (as set forth in the Restricted Stock Purchase Agreement,
attached hereto as Exhibit C-1).

                      (ii) As a condition to exercising this Option for unvested
Shares, the Optionee shall execute the Restricted Stock Purchase Agreement.

                      (iii) This Option may not be exercised for a fraction of a
Share.





                                       2
<PAGE>   15

               (b)    Method of Exercise. This Option shall be exercisable by
delivery of an exercise notice in the form attached as Exhibit A (the "Exercise
Notice") which shall state the election to exercise the Option, the number of
Shares with respect to which the Option is being exercised, and such other
representations and agreements as may be required by the Company. The Exercise
Notice shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanies by the aggregate
Exercise Price.

               No Shares shall be issued pursuant to the exercise of an Option
unless such issuance and such exercise complies with Applicable Laws. Assuming
such compliance, for income tax purposes the Shares shall be considered
transferred to the Optionee on the date which the Option is exercised with
respect to such Shares.

        3.     Optionee's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Option
is exercised, the Optionee shall, if required by the Company, concurrently with
the exercise of all or any portion of this Option, deliver to the Company his or
her Investment Representation Statement in the form attached hereto as Exhibit
B.

        4.     Lock-Up Period. Optionee hereby agrees that, is so requested by
the Company or any representative of the underwriters (the "Managing
Underwriter") in connection with any registration of the offering of any
securities of the Company under the Securities Act, Optionee shall not sell or
otherwise transfer any Shares or other securities of the Company during the 180
day period (or such other period as may be requested in writing by the Managing
Underwriter and agreed to in writing by the Company) (the "Market Standoff
Period") following the effective date of a registration statement of the Company
filed under the Securities Act. Such restriction shall apply only to the first
registration statement of the Company to become effective under the Securities
Act that includes securities to be sold on behalf of the Company to the public
in an underwritten public offering under the Securities Act. The Company may
impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such Market Standoff Period.

        5.     Method of Payment. Payment of the aggregate Exercise Price shall
be by any of the following, or a combination thereof, at the election of the
Optionee.

               (a)    cash;

               (b)    check;

               (c)    consideration received by the Company under a formal
cashless exercise program adopted by the Company in connection with the Plan; or





                                       3
<PAGE>   16

               (d)    surrender of other Shares which, (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

        6.     Restrictions on Exercise. This Option may not be exercised until
such time as the Plan has been approved by the stockholders 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
Law.

        7.     Nontransferability 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 Optionee. The terms
of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

        8.     Term of Option. This Option may be exercised only within the term
set out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.

        9.     Tax Consequences. Set forth below is a brief summary as of the
date of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD
CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

               (a)    Exercise of ISO. If this Option qualifies as an ISO, there
will be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

               (b)    Exercise of ISO Following Disability. If the Optionee
ceases to be an Employee as a result of a disability that is not a total and
permanent disability as defined in Section 22(e)(3) of the Code, to the extent
permitted on the date of termination, the Optionee must exercise an ISO within
three months of such termination for the ISO to be qualified as an ISO.

               (c)    Exercise of Nonstatutory Stock Option. There may be a
regular federal income tax liability upon the exercise of a Nonstatutory Stock
Option. The Optionee will be treated as having received compensation income
(taxable at ordinary income tax rates) equal to the excess, if any, of the Fair
Market Value of the Shares on the date of exercise over the Exercise Price. If
Optionee is an Employee or a former Employee, the Company will be required to
withhold from Optionee's compensation or





                                       4
<PAGE>   17

collect from Optionee and pay to the applicable taxing authorities an amount in
cash equal to a percentage of this compensation income at the time of exercise,
and may refuse to honor the exercise and refuse to deliver Shares if such
withholding amounts are not delivered at the time of exercise.

               (d)    Disposition of Shares. In the case of an NSO, if Shares
are held for at least one year, any gain realized on disposition of the Shares
will be treated as long-term capital gain for federal income tax purposes. In
the case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes. If Shares purchased under an ISO
are disposed of within one year after exercise or two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the Exercise Price and the lesser of (i) the Fair Market Value of the
Shares on the date of exercise, or (ii) the sale price of the Shares. Different
rules may apply if the Shares are subject to a substantial risk of forfeiture
(within the meaning of section 83) at the time of purchase. Any additional gain
will be taxed as capital gain, short-term depending on the period that the ISO
Shares were held.

               (e)    Notice of Disqualifying Disposition of ISO Shares. If the
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (i) the date two years after the Date of Grant, or (ii) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

               (f)    Section 83(b) Election for Unvested Shares Purchased
Pursuant to Options. With respect to the exercise of an Option for unvested
Shares, an election may be filed by the Optionee with the Internal Revenue
Service, within 30 days of the purchase of the Shares, electing pursuant to
Section 83(b) of the Code to be taxed currently on any difference between the
purchase price of the Shares and their Fair Market Value on the date of
purchase. In the case of a Nonstatutory Stock Option, this will result in a
recognition of taxable income to the Optionee on the date of exercise, measured
by the excess, if any, of the fair market value of the Shares, at the time the
Option is exercised over the purchase price for the Shares. Absent such an
election, taxable income will be measured and recognized by Optionee at the time
or times on which the Company's Repurchase Option lapses. In the case of an
Incentive Stock Option, such an election will result in a recognition of income
to the Optionee for alternative minimum tax purposes on the date of exercise,
measured by the excess, if any, of the fair market value of the Shares, at the
time the option is exercised, over the purchase price for the Shares. Absent
such an election, alternative minimum taxable income will be measured and
recognized by Optionee at the time or times on which the Company's Repurchase
Option lapses. Optionee is strongly encouraged to seek the advice of his or her
own tax consultants in connection with the purchase of the Shares





                                       5
<PAGE>   18

and the advisability of filing of the Election under Section 83(b) of the Code.
A form of Election under Section 83(b) is attached hereto as Exhibit C-5 for
reference.

        OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY AND NOT
THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF OPTIONEE
REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON OPTIONEE'S
BEHALF.

        10.    Entire Agreement; Governing Law. The Plan is incorporated herein
by reference. The Plan and this Option Agreement constitute the entire agreement
of the parties with respect to the subject matter hereof and supercede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by the internal substantive laws, but not
the choice of law rules, of California.

        11.    No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND
AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS
EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

        Optionee acknowledges receipt of a copy of the Plan and represents that
he or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof. Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option. Optionee
further agrees to notify the Company upon any change in the residence address
indicated below.

                             1998 STOCK OPTION PLAN

                                 EXERCISE NOTICE


Boulder Creek Engineering
133 Mission Street, Suite 104
Santa Cruz, California 95060


Attention:     Danielle L. Hoyer
               Secretary of the Company


        1.     Exercise of Option.  Effective as of today, ____________________,
the undersigned ("Optionee") hereby elects to exercise Optionee's option to
purchase _________ shares of the Common Stock (the "Shares") of Boulder Creek
Engineering (the "Company") under and pursuant to the 1998 Stock Option Plan
(the "Plan") and the Stock Option Agreement dated ___________, 1998 (the "Option
Agreement").

        2.     Delivery of Payment. Purchaser herewith delivers to the Company
the full purchase price of the Shares, as set forth in the Option Agreement.

        3.     Representations of Optionee. Optionee acknowledges that Optionee
has received, read and understood the Plan and the Option Agreement and agrees
to abide by and be bound by their terms and conditions.

        4.     Rights as Stockholder. Until the issuance of the Shares (as
evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company), no right to vote or receive dividends
or any other rights as a stockholder shall exist with respect to the Optioned
Stock, notwithstanding the exercise of the Option. The Shares shall be issued to
the Optionee as soon as practicable after the Option is exercised. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date of issuance except as provided in Section 12 of the Plan.

        5.     Company's Right of First Refusal. Before any Shares held by
Optionee or any transferee (either being sometimes referred to herein as the
"Holder"), may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

               (a)    Notice of Proposed Transfer. The Holder of the Shares
shall deliver to the Company a written notice (the "Notice"), stating: (i) the
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the
name of each proposed purchaser or other transferee ("Proposed Transferee");
(iii) the number of Shares to be transferred to each Proposed Transferee; and
(iv) the bona fide cash price or other






<PAGE>   21

consideration for which the Holder proposes to transfer the Shares (the "Offered
Price"), and the Holder shall offer the shares at the Offered Price to the
Company or its assignee(s).

               (b)    Exercise of Right of First Refusal. At any time within
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
Subsection (c) below.

               (c)    Purchase Price. The purchase price ("Purchase Price") for
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (d)    Payment. Payment of the Purchase Price shall be made, at
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

               (e)    Holder's Right to Transfer. If all of the Shares proposed
in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section, then the
Holder may sell or otherwise transfer such Shares to the Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 120 days after the date of the Notice, that any
such sale or other transfer is effected in accordance with any applicable
securities laws and that the Proposed Transferee agrees in writing that the
provisions of this Section shall continue to apply to the Shares in the hands of
such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, a new Notice shall be
given to the Company, and the Company and/or its assignees shall again be
offered the Right of First Refusal before any Shares held by the Holder may be
sold or otherwise transferred.

               (f)    Exception for Certain Family Transfers. Anything to the
contrary contained in this section notwithstanding, the transfer of any or all
of the shares during the Optionee's lifetime or on the Optionee's death by will
or intestacy to the Optionee's immediate family or a trust for the benefit of
the Optionee's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.





                                       2
<PAGE>   22

               (g)    Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the first sale of Common Stock of
the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended.

        6.     Tax Consultation. Optionee understands that Optionee may suffer
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares. Optionee represents that Optionee has consulted with any tax
consultants Optionee deems advisable in connection with the purchase or
disposition of the Shares and that Optionee is not relying on the Company for
any tax advice.

        7.     Restrictive Legends and Stop-Transfer Orders.

               (a)    Legends. Optionee understands and agrees that the Company
shall cause the legends set forth below or legends substantially equivalent
thereto, to be placed upon any certificate(s) evidencing ownership of the Shares
together with any other legends that may be required by the Company or by state
or federal securities laws:

               THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
               THE SECURITIES ACT OF 1933 (THE "ACT"), AND MAY NOT BE OFFERED,
               SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
               UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
               COUNSEL, SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
               OFFER SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
               THEREWITH.

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
               RESTRICTIONS ON TRANSFER AND RIGHT OF FIRST REFUSAL OPTIONS HELD
               BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE
               NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE
               SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE

ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               (c)    Refusal to Transfer. The Company shall not be required
(i) to transfer on its books any Shares that have been sold or otherwise
transferred in violation of any of the provisions of this Agreement or (ii) to
treat as owner of such Shares or to

accord the right to vote or pay dividends to any purchaser or other transferee
to whom such Shares shall have been so transferred.

        8.     Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Optionee and his or her heirs, executors, administrators, successors and
assigns.

        9.     Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Optionee or by the Company forthwith to the
Administrator which shall review such dispute at its next regular meeting. The
resolution of such a dispute by the Administrator shall be final and binding on
all parties.

        10.    Governing Law; Severability. This Agreement is governed by the

Agreement, the Option Agreement and the Investment Representation Statement
constitute the entire agreement of the parties with respect to the subject
matter hereof and supersede in their entirety all prior undertakings and
agreements of the Company and Optionee with respect to the subject matter

                       INVESTMENT REPRESENTATION STATEMENT


OPTIONEE:

COMPANY:              BOULDER CREEK ENGINEERING

SECURITY:             COMMON STOCK

AMOUNT:

DATE:


        In connection with the purchase of the above listed securities, the
undersigned Optionee represents to the Company the following:

        (a)    Optionee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Optionee is
acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

        (b)    Optionee acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Optionee's investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be available if
Optionee's representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the securities, or for a period of one year or any other fixed
period in the future. Optionee further understands that the Securities must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. Optionee further
acknowledges and understands that the Company is under no obligation to register
the Securities. Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company, a legend prohibiting their
transfer without the consent of the Commissioner of Corporations of the State of
California and any other legend required under applicable state securities laws.

        (c)    Optionee is familiar with the provisions of Rule 701 and
Rule 144, each promulgated under the Securities Act, which, in substance, permit
limited public resale of





<PAGE>   25

"restricted securities" acquired, directly or indirectly from the issuer
thereof, in a nonpublic offering subject to the satisfaction of certain
conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the
time of the grant of the Option to the Optionee, the exercise will be exempt
from registration under the Securities Act. In the event the Company becomes
subject to the reporting requirements of Section 13 or 15(d) of the Securities
Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any
market stand-off agreement may require) the securities exempt under Rule 701 may
be resold, subject to the satisfaction of certain of the conditions specified by
Rule 144, including: (1) the resale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934; and in
the case of an affiliate, (2) the availability of certain public information
about the Company, (3) the amount of Securities being sold during any three
month period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Option, then the Securities may be resold in certain
limited circumstances subject to the provisions of Rule 144, which require the
resale to occur not less than one year after the later of the date the
Securities were sold by the Company or the date the Securities were sold by an
affiliate of the Company, within the meaning of Rule 144; and, in the case of
acquisition of the Securities by an affiliate, or by a nonaffiliate who
subsequently holds the Securities less than two years, the satisfaction of the
conditions set forth in Sections (1), (2), (3) and (4) of the paragraph
immediately above.

        (d)    Optionee further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

                            BOULDER CREEK ENGINEERING

                             1998 STOCK OPTION PLAN

                       RESTRICTED STOCK PURCHASE AGREEMENT


        THIS AGREEMENT is made between __________________ (the "Purchaser") and
Boulder Creek Engineering (the "Company") as of __________________.


                                    RECITALS

        (1)    Pursuant to the exercise of the stock option (grant number _____)
granted to Purchaser under the Company's 1998 Stock Option Plan (the "Plan") and
pursuant to the Stock Option Agreement (the "Option Agreement") dated __________
by and between the Company and Purchaser with respect to such grant, which Plan
and Option Agreement are hereby incorporated by reference, Purchaser has elected
to purchase ____________ of those shares which have not become vested under the
vesting schedule set forth in the Option Agreement ("Unvested Shares"). The
Unvested Shares and the shares subject to the Option Agreement which have become
vested are sometimes collectively referred to herein as the "Shares".

        (2)    As required by the Option Agreement, as a condition to
Purchaser's election to exercise the option, Purchaser must execute this
Restricted Stock Purchase Agreement, which sets forth the rights and obligations
of the parties with respect to Shares acquired upon exercise of the Option.

        1.     Repurchase Option.

               (a)    If Purchaser's status as a Service Provider is terminated
for any reason, including for cause, death, and Disability, the Company shall
have the right and option to purchase from Purchaser, or Purchaser's personal
representative, as the case may be, all of the Purchaser's Unvested Shares as of
the date of such termination at the price paid by the Purchaser for such Shares
(the "Repurchase Option").

               (b)    Upon the occurrence of a termination, the Company may
exercise its Repurchase Option by delivering personally or by registered mail,
to Purchaser (or his transferee or legal representative, as the case may be),
within one (1) year of the termination, a notice in writing indicating the
Company's intention to exercise the Repurchase Option and setting forth a date
for closing not later than thirty (30) days from the mailing of such notice. The
closing shall take place at the Company's office. At the closing, the holder of
the certificates for the Unvested Shares being transferred shall deliver the
stock certificate or certificates evidencing the Unvested Shares, and the
Company shall deliver the purchase price therefor.





<PAGE>   27

               (c)    At its option, the Company may elect to make payment for
the Unvested Shares to a bank selected by the Company. The Company shall avail
itself of this option by a notice in writing to Purchaser stating the name and
address of the bank, date of closing, and waiving the closing at the Company's
office.

               (d)    If the Company does not elect to exercise the Repurchase
Option conferred above by giving the requisite notice within ninety (90) days
following the termination, the Repurchase Option shall terminate.

               (e)    The Repurchase Option shall terminate in accordance with
the Vesting Schedule in Optionee's Option Agreement.

        2.     Transferability of the Shares; Escrow.

               (a)    Purchaser hereby authorizes and directs the secretary of
the Company, or such other person designated by the Company, to transfer the
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

               (b)    To insure the availability for delivery of Purchaser's
Unvested Shares upon repurchase by the Company pursuant to the Repurchase Option
under Section 1, Purchaser hereby appoints the secretary, or any other person
designated by the Company as escrow agent, as its attorney in fact to sell,
assign and transfer unto the Company, such Unvested Shares, if any, repurchased
by the Company pursuant to the Repurchase Option and shall, upon execution of
this Agreement, deliver and deposit with the secretary of the Company, or such
other person designated by the Company, the share certificates representing the
Unvested Shares, together with the stock assignment duly endorsed in blank,
attached hereto as Exhibit C-2. The Unvested Shares and stock assignment shall
be held by the secretary in escrow, pursuant to the Joint Escrow Instructions of
the Company and Purchaser attached as Exhibit C-3 hereto, until the Company
exercises its purchase right as provided in Section 1, until such Unvested
Shares are vested, or until such time as this Agreement no longer is in effect.
As a further condition to the Company's obligations under this Agreement, the
spouse of the Purchaser, if any, shall execute and deliver to the Company the
Consent of Spouse attached hereto as Exhibit C-4. Upon vesting of the Unvested
Shares, the escrow agent shall promptly deliver to the Purchaser the certificate
or certificates representing such Shares in the escrow agent's possession
belonging to the Purchaser, and the escrow agent shall be discharged of all
further obligations hereunder; provided, however, that the escrow agent shall
nevertheless retain such certificate or certificates as escrow agent if so
required pursuant to other restrictions imposed pursuant to this Agreement.

               (c)    The Company, or it designee, shall not be liable for any
act it may do or omit to do with respect to holding the Shares in escrow and
while acting in good faith and in the exercise of its judgment.





<PAGE>   28

               (d)    Transfer or sale of the Shares is subject to restrictions
on transfer imposed by any applicable state and federal securities laws. Any
transferee shall hold such Shares subject to all the provisions hereof and the
Exercise Notice executed by the Purchaser with respect to any Unvested Shares
purchased by Purchaser and shall acknowledge the same by signing a copy of this
Agreement.

        3.     Ownership, Voting Right, Duties. This Agreement shall not affect
in any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.

        4.     Legends. The share certificate evidencing the Shares issued
hereunder shall be endorsed with the following legend (in addition to any legend
required under applicable state securities laws):

        THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT
BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY.

        5.     Adjustment for Stock Split. All references to the number of
Shares and the purchase price of the Shares in this Agreement shall be
appropriately adjusted to reflect any stock split, stock dividend or other
change in the Shares which may be made by the Company after the date of this
Agreement.

        6.     Notices. Notices required hereunder shall be given in person or
by registered mail to the address of Purchaser shown on the records of the
Company, and to the Company at their respective principal executive offices.

        7.     Survival of Terms. This Agreement shall apply to and bind
Purchaser and the Company and their respective permitted assignees and
transferees, heirs, legatees, executors, administrators and legal successors.

        8.     Section 83(b) Election. Purchaser hereby acknowledges that he or
she has been informed that, with respect to the exercise of an Option for
Unvested Shares, an election may be field by the Purchaser with the Internal
Revenue Service, within 30 days of the purchase of the Shares, electing pursuant
to Section 83(b) of the Code to be taxed currently on any difference between the
purchase price of the Shares and their Fair Market Value on the date of
purchase. In the case of a Nonstatutory Stock Option, this will result in a
recognition of taxable income to the Purchaser on the date of exercise, measured
by the excess, if any, of the Fair Market Value of the Shares, at the time the
Option is exercised over the purchase price for the Shares. Absent such an
election, taxable income will be measured and recognized by Purchaser at the
time or times on which the Company's Repurchase Option lapses. In the case of
an Incentive Stock Option, such an election will result in a recognition of
income to the Purchaser for alternative minimum tax purposes on the date of
exercise, measured by the excess, if any,






<PAGE>   29

of the Fair Market Value of the Shares. Absent such an election, alternative
minimum taxable income will be measured and recognized by Purchaser at the time
or times on which the Company's Repurchase Option lapses. Purchaser is strongly
encouraged to seek the advice of his or her own tax consultants in connection
with the purchase of the Shares and the advisability of filing of the Election
under Section 83(b) of the Code. A form of Election under Section 83(b) is
attached hereto as Exhibit C-5 for reference.

        PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER'S SOLE RESPONSIBILITY AND
NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF
PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON
PURCHASER'S BEHALF.

        9.     Representations. Purchaser has reviewed with his own tax advisors
the federal, state, local and foreign tax consequences of this investment and
the transactions contemplated by this Agreement. Purchaser is relying solely on
such advisors and not on any statements or representations of the Company or any
of it agents. Purchaser understands that he (and not the Company) shall be
responsible for his own tax liability that may arise as a result of this
investment or the transactions contemplated by this Agreement.

        10.    Governing Law. This Agreement shall be governed by the internal
substantive laws, but not the choice of law rules, of California.

        Purchaser represents that he has read this Agreement and is familiar
with its terms and provisions. Purchaser hereby agrees to accept as binding,
conclusive and final all decisions or interpretations of the Board upon any
questions arising under this Agreement.


        IN WITNESS WHEREOF, this Agreement is deemed made as of the date first
set forth above.

Company's repurchase option set forth in the Agreement, the Company shall give
to Purchaser and you a written notice specifying the number of shares of stock
to be purchased, the purchase price, and the time for a closing hereunder at the
principal office of the Company. Purchaser and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in

        3.     Purchaser irrevocably authorizes the Company to deposit with you

parties. You shall not be personally liable for any act you may do or omit to do
hereunder as Escrow Agent or as attorney in fact for Purchaser while acting in
good faith, and any act done or omitted by you pursuant to the advice of your
own attorneys shall be conclusive evidence of such good faith.

warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree, you
shall not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

identity, authorities or rights of the parties executing or delivering or
purporting to execute or deliver the Agreement or any documents or papers
deposited or called for hereunder.
