Stock with respect to which Incentive Options granted under this Plan and any
other plan of the Company or any Affiliated Company become exercisable for the

transferable except by will or the laws of decent and distribution, and during

          ---------------------
6.2 hereof, an Offeree shall have the rights of a shareholder with respect to

          ---------------------------

achieved, and any other conditions on which the nontransferability of the
Restricted Stock and the Company's right of repurchase shall lapse.  Subsequent
to such date or dates or the attainment of such specified performance goals or
objectives or other conditions, the shares as to which all restrictions have
lapsed shall no longer be Restricted Stock and shall be deemed "vested."
                                                                ------

note.

     In the event that the Company at any time proposed to sell substantially
all of its assets, merge into, consolidate with or to enter into any other
reorganization in which the Company is not the surviving corporation, or if the
Company is the surviving corporation and the ownership of the voting power of
the Company's capital stock changes by more than 50% as a result of such
transaction, the Plan and all unexercised Options and Rights to Purchase shall
terminate upon the effective date of such transaction unless provision is made
in writing in connection with such transaction for (a) the continuance of the
Plan and for the assumption of outstanding Options or Rights to Purchase, or the
substitution of such Options and Rights to Purchase of new options and new
rights to purchase of comparable value covering shares of a successor
corporation, with appropriate adjustments as to the number and kind of shares
and prices, in which event the Plan and such Options and Rights to Purchase, or
the new options and rights to purchase substituted therefor, shall continue in
the manner and under the terms so provided, or (b) the substitution for the Plan
and outstanding Options and Rights to Purchase of a program or plan to provide
rights to the Participants to receive on exercise of such rights, the type and
amount of consideration they would have received had they exercised all Options
or Rights to Purchase prior to such transaction and less the aggregate Exercise
Price or Purchase Price therefor.  If such provision is not made in such
transaction, then the Administrator shall cause written notice of the proposed
transaction to be given to all Participants no less than fifteen (15) days prior
to the anticipated effective date of the proposed transaction.

                     AMENDMENT AND TERMINATION OF THE PLAN
                     -------------------------------------

     9.1  Amendments.  The Board may from time to time alter, amend, suspend or
          ----------
terminate the Plan in such respects as the Board may deem advisable.  No such
alteration, amendment, suspension or termination shall be made which shall
substantially affect or impair the rights of any Participant under an
outstanding Option or Right to Purchase without such Participant's consent.  The
Board may alter or amend the Plan to comply with requirements under the Code
relating to Incentive Options or other types of options which give Optionees
more favorable tax treatment than that applicable to Options granted under this
Plan as of the date of its adoption.  Upon any such alteration or amendment, any
outstanding Option granted hereunder may, if the Administrator so determines and
if permitted by applicable law, be subject to the more favorable tax treatment
afforded to an Optionee pursuant to such terms and conditions.  However, the
Board shall not, without the approval of the Corporation's shareholders (i)
increase the maximum number of shares issuable under the Plan, except for
permissible adjustments under Article 4, (ii) materially modify the eligibility
requirements for grants of Options, or (iii) materially increase the benefits
accruing to Option holders.  In addition, the Board shall also obtain
shareholder approval of any Plan amendment to the extent necessary and desirable
to comply with applicable laws, rules or regulations.

     9.2  Plan Termination.  Unless the plan shall theretofore have been
          ----------------
terminated by the Board, the Plan shall terminate on the tenth (10) anniversary
of the Effective Date and no Options

                                      -9-


or Rights to Purchase may be granted under the Plan thereafter, but Options and
Rights to Purchase then outstanding shall continue in effect in accordance with
their respective terms.

                                TAX WITHHOLDING
                                ---------------

     The Company shall have the power to withhold, or require a Participant to
remit to the Company, an amount sufficient to satisfy any applicable Federal,
State, and local tax withholding requirements with respect to any Options
exercised or restricted Stock issued under the Plan.  To the extent permissible
under applicable tax, securities and other laws, the Administrator may, in its
sole discretion and upon such terms and conditions as it may deem appropriate,
permit a Participant to satisfy his or her obligation to pay any such tax, in
whole or in part, up to an amount determined on the basis of the highest
marginal tax rate applicable to such Participant, by (a) directing the Company
to apply shares of Common Stock to which the Participant is entitled as a result
of the exercise of an Option or as a result of the lapse of restrictions on
Restricted Stock or (b) delivering to the Company shares of Common Stock owned
by the Participant.  The shares of Common Stock so applied or delivered in
satisfaction of the Participant's tax withholding obligation shall be valued at
their Fair Market Value as of the date of measurement of the amount of income
subject to withholding.

                                 -------------

     11.1 Benefits not Alienable.  Other than as provided above, benefits under
          ----------------------
the Plan may not be assigned or alienated, whether voluntarily or involuntarily.
Any unauthorized attempt at assignment, transfer, pledge or other disposition
shall be without effect.

     11.2 No Enlargement of Employee Rights.  This Plan is strictly a voluntary
          ---------------------------------
undertaking on the part of the Company and shall not be deemed to constitute a
contract between the Company and any Participant to be consideration for, or an
inducement to, or a condition of, the employment of any Participant.  Nothing
contained in the Plan shall be deemed to give the right to any Participant to be
retained as an employee of the Company or any Affiliated Company or to interfere
with the right of the Company or any Affiliated Company to discharge any
Participant at any time.

     11.3 Application of Funds.  The proceeds received by the Company from the
          --------------------
sale of Common Stock pursuant to Option Agreements and Stock Purchase
Agreements, except as otherwise provided herein, will be used for general
corporate purposes.

                           THE KEITH COMPANIES, INC.

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


     This Incentive Stock Option Agreement (the "Agreement") is entered into as
                                                 ---------
of _______, by and between The Keith Companies, Inc. (formerly known as The
Keith Companies - Inland Empire, Inc.), a California corporation (the "Company")
                                                                       -------
and _________ (the "Optionee") pursuant to the Company's Amended and Restated
                    --------
1994 Stock Incentive Plan (the "Plan").
                                ----

     1.   Grant of Option.   The Company hereby grants to Optionee an option
          ---------------
(the "Option") to purchase all or any portion of a total of ________ (____)
      ------
shares (the "Shares") of the Common Stock of the Company at a purchase price of
             ------
_________ (____) per share (the "Exercise Price"), subject to the terms and
                                 --------------
conditions set forth herein and the provisions of the Plan.  This Option is
intended to qualify as an "incentive stock option" as defined in Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code").  If this Option
                                                    ----
fails in whole or in part to qualify as an incentive stock option, then this
Option shall to that extent constitute a nonqualified stock option.

     2.   Vesting of Option.   The Optionee may not purchase any shares by
          -----------------
exercise of this Option between the date of this Agreement and the first
anniversary date hereof.  On and after the following anniversary dates of this
Agreement this Option may be exercised up to the indicated number of shares
covered by this Option:





                                      Percentage             Cumulative
        Anniversary                    Initially             Percentage
            Date                      Exercisable            Exercisable
- ----------------------------   -------------------------   ---------------
                                                      
First                                    20%                      20%
Second                                   20%                      40%
Third                                    20%                      60%
Fourth                                   20%                      80%
Fifth                                    20%                     100%



     No additional shares shall vest after the date of termination of Optionee's
"Continuous Service" (as defined in Section 3 below), but this Option shall
continue to be exercisable in accordance with Section 3 hereof with respect to
that number of shares that have vested as of the date of termination of
Optionee's Continuous Service; provided, however, if the Optionee shall take a
leave of absence exceeding thirty (30) days which is authorized by the Company
in writing and the Optionee recommences providing services to the Company at the
end of such authorized leave of absence, then the vesting date(s) for any
Option(s) that are unvested at the date of commencement of such leave of absence
shall be extended by the length of such leave of absence.

     3.   Term of Option.   Optionee's right to exercise this Option shall
          --------------
terminate upon the first to occur of the following:


          (a) the expiration of ten (10) years from the date of this Agreement.

          (b) the expiration of thirty (30) days from the date of termination of
     Optionee's Continuous Service if such termination occurs for any reason
     other than permanent disability or death or voluntary resignation:
     provided, however, that if Optionee dies during such thirty-day period the
     provisions of Section 3(d) below shall apply;

          (c) the expiration of one (1) year from the date of termination of
     Optionee's Continuous Service if such termination is due to permanent
     disability of the Optionee (as defined in Section 22(e)(3) of the Code);

          (d) the expiration of one (1) year from the date of termination of
     Optionee's Continuous Service if such termination is due to Optionee's
     death or if death occurs during the thirty-day period following termination
     of Optionee's Continuous Service pursuant to Section 3(b) above; or

          (e) the expiration of ninety (90) days from the date of termination of
     Optionee's Continuous Service if such termination is due to voluntary
     resignation; provided, however that if Optionee dies during such ninety-day
     period the provisions of Section 3(d) above shall apply.


     As used herein, the term "Continuous Service" means (i) employment by
                               ------------------
either the Company or any parent or subsidiary corporation of the Company, or by
a corporation or a parent or subsidiary of a corporation issuing or assuming a
stock option in a transaction to which Section 424(a) of the Code applies, which
is uninterrupted except for vacations, illness (except for permanent disability
as defined in Section 22(e)(3) of the Code), or leaves of absence which are
approved in writing by the Company or any other employer corporations, if
applicable, (ii) service as a member of the Board of Directors of the Company
until Optionee resigns, is removed from office, or Optionee's term of office
expires and he or she is not reelected, or (iii) so long as Optionee is engaged
as a consultant or service provider to the Company or other corporation referred
to in clause (i) above.

     4.   Exercise of Option.   On or after the vesting of any portion of this
          ------------------
Option in accordance with Section 2 above, and until termination of this Option
in accordance with Section 3 above, the portion of this Option which has vested
may be exercised in whole or in part by the Optionee (or, after his or her
death, by the person designated in Section 5 below) upon delivery of the
following to the Company at its principal executive offices:

          (a) a written notice of exercise which identifies this Agreement and
     states the number of Shares then being purchased (but no fractional Shares
     may be purchased).

          (b) a check or cash in the amount of the Exercise Price (or payment of
     the Exercise Price in such other form of lawful consideration as the
     Administrator may approve from time to time under the provisions of Section
     5.3 of the Plan);

                                       2


          (c) a check or cash in the amount reasonably requested by the Company
     to satisfy the Company's withholding obligations under Federal, State or
     other applicable tax laws with respect to the taxable income, if any,
     recognized by the Optionee in connection with the exercise of this Option
     (unless the Company and Optionee shall have made other arrangements for
     deductions or withholding from Optionee's wages, bonus or other
     compensation payable to Optionee, or by the withholding of Shares issuable
     upon exercise of this Option or the delivery of Shares owned by the
     Optionee in accordance with Section 10 of the Plan, provided such
     arrangements satisfy the requirements of applicable tax laws); and

          (d) a letter, if requested by the Company, in such form and substance
     as the Company may require, setting forth the investment intent of the
     Optionee, or person designated in Section 5 below, as the case may be.

     5.   Death of Optionee; No Assignment.   The rights of the Optionee under
          --------------------------------
this Agreement may not be assigned or transferred except by will or by the laws
of descent and distribution, and may be exercised during the lifetime of the
Optionee only by such Optionee.  Any attempt to sell, pledge, assign,
hypothecate, transfer or dispose of this Option in contravention of this
Agreement or the Plan shall be void and shall have no effect.  If the Optionee's
Continuous Service terminates as a result of his or her death, and provided
Optionee's rights hereunder shall have vested pursuant to Section 2 hereof,
Optionee's legal representative, his or her legatee, or the person who acquired
the right to exercise this Option by reason of the death of the Optionee
(individually, a "Successor") shall succeed to the Optionee's rights and
                  ---------
obligations under this Agreement.  After the death of the Optionee, only a
Successor may exercise this Option.


     6.   Representations and Warranties of Optionee.
          ------------------------------------------

          (a) Optionee represents and warrants that this Option is being
     acquired by Optionee for Optionee's personal account, for investment
     purposes only, and not with a view to the distribution, resale or other
     disposition thereof.

          (b) Optionee acknowledges that the Company may issue Shares upon the
     exercise of the Option without registering such Shares under the Securities
     Act of 1933, as amended (the "Act"), on the basis of certain exemptions
                                   ---
     from such registration requirement.  Accordingly, Optionee agrees that his
     or her exercise of the Option may be expressly conditioned upon his or her
     delivery to the Company of an investment certificate including such
     representations and undertakings as the Company may reasonably require in
     order to assure the availability of such exemptions, including a
     representation that Optionee is acquiring the Shares for investment and not
     with a present intention of selling or otherwise disposing thereof and an
     agreement by Optionee that the certificates evidencing the Shares may bear
     a legend indicating such non-registration under the Act and the resulting
     restrictions on transfer.  Optionee acknowledges that, because Shares
     received upon exercise of an Option may be unregistered, Optionee may be
     required to hold the Shares indefinitely unless they are subsequently
     registered for resale under the Act or an exemption from such registration
     is available.

                                       3


          (c) Optionee acknowledges receipt of a copy of the Plan and
     understands that all rights and obligations connected with this Option are
     set forth in this Agreement and in the Plan.

     7.   Restrictive Legends.   Optionee hereby acknowledges that Federal
          -------------------
securities laws and the securities laws of the State in which he or she resides
may require the placement of certain restrictive legends upon the Shares issued
upon exercise of this Option, and Optionee hereby consents to the placing of any
such legends upon certificates evidencing the Shares as the Company, or its
counsel, may deem necessary or advisable.

     8.   Limitation of Company's Liability for Nonissuance.   The Company
          -------------------------------------------------
agrees to use its reasonable best efforts to obtain from any applicable
regulatory agency such authority or approval as may be required in order to
issue and sell the Shares to the Optionee pursuant to this Option.  Inability of
the Company to obtain, from any such regulatory agency, authority or approval
deemed by the Company's counsel to be necessary for the lawful issuance and sale
of the Shares hereunder and under the Plan shall relieve the Company of any
liability in respect of the nonissuance or sale of such shares as to which such
requisite authority or approval shall not have been obtained.

     9.   Call Option.
          -----------

          (a) Upon the termination of the Optionee's Continuous Service for any
     reason, including, without limitation, death or permanent disability,
     voluntary termination or involuntary termination without cause (or in the
     event Optionee is a transferee if original Optionee's Continuous Service
     terminates), the Company shall have the right to purchase for cash all or
     any portion of the Shares acquired pursuant to the exercise of this Option
     which are held by Optionee (the "Purchased Shares").
                                      ----------------

          (b) The Company may purchase all or any portion of such Purchased
     Shares at a per Share price equal to the greater of (i) the Fair Market
     Value of such shares as defined in the Plan and (ii) the original purchase
     price paid by Purchaser, plus one percent (1%) per month on a cumulative,
     compound basis.

          (c) Any Call Option may be exercised by delivery of written notice
     thereof (the "Call Notice") to Optionee within sixty (60) days of the later
                   -----------
     of (i) the Termination Date or (ii) the dates of exercise of the option to
     which the Purchased Shares relate (the "Call Option Exercise Period").  The
                                             ---------------------------
     Call Notice shall state that the Company has elected to exercise the Call
     Option, and the number and price of the Purchased Shares with respect to
     which the Call Option is being exercised.

          (d) The closing of any purchase of Purchased Shares pursuant to the
     exercise of the Call Option pursuant to this paragraph 9 shall take place
     as soon as reasonably practicable and in no event later than ten (10) days
     after termination of the applicable Call Option Exercise Period at the
     principal office of the Company, or at such other time and location as the
     parties to such purchase may mutually determine.  At the closing of any

                                       4


     purchase and sale of Purchased Shares pursuant to this Paragraph 9,
     Optionee shall deliver to the Company a certificate or certificates
     representing the Purchased Shares to be purchased by the Company duly
     endorsed, or with stock powers duly endorsed, for transfer with signature
     guaranteed, free and clear of any lien or encumbrance, with any necessary
     stock transfer tax stamps affixed, and the Company shall pay to Optionee
     the purchase price of the Purchased Shares being purchased by the Company.
     The delivery of a certificate or certificates for Purchased Shares by any
     Person selling Purchased Shares pursuant to this Paragraph 9 shall be
     deemed a representation and warranty by such Person that: (i) such Person
     has full right, title and interest in and to such Purchased Shares; (ii)
     such Person has all necessary power and authority and has taken all
     necessary action to sell such Purchased Shares as contemplated; and (iii)
     such Purchased Shares are free and clear of any and all liens or
     encumbrances.

          (e) The provisions of this Paragraph 9 shall automatically terminate
     upon the earlier to occur of (i) in the event that the Company sells
     substantially all of its assets, merges into, consolidates with or enters
     into any other reorganization (including the sale of substantially all of
     its assets) in which the Company is not the surviving corporation (other
     than one in which 50% or more of the outstanding capital stock of the
     surviving corporation is held by the Company's current stockholders), or if
     the Company is the surviving corporation and ownership of the outstanding
     capital stock of the Company following the transaction changes by 50% or
     more as a result of such transaction, or (ii) on the date of closing of an
     initial public offering registered on Form S-1 (or any successor form)
     under the Act of securities of the Company.

     10.  Right of First Refusal.
          ----------------------

          (a) The Purchased Shares, as defined above, acquired pursuant to the
     exercise of this Option may be sold by the Optionee only in compliance with
     the provisions of this Section 10, and subject in all cases to compliance
     with the provisions of Section 6(b) hereof.  Prior to any intended sale,
     Optionee shall first give written notice (the "Offer Notice") to the
                                                    ------------
     Company specifying (i) his or her bona fide intention to sell or otherwise
     transfer such Shares, (ii) the name and address of the proposed
     purchaser(s), (iii) the number of Shares the Optionee proposes to sell (the
     "Offered Shares"), (iv) the price for which he or she proposes to sell the
      --------------
     Offered Shares, and (v) all other material terms and conditions of the
     proposed sale.

          (b) Within thirty (30) days after receipt of the Offer Notice, the
     Company or its nominee(s) may elect to purchase all or any portion of the
     Offered Shares at the price and on the terms and conditions set forth in
     the Offer Notice by delivery of written notice (the "Acceptance Notice") to
                                                          -----------------
     the Optionee specifying the number of Offered Shares that the Company or
     its nominees elect to purchase.  Within fifteen (15) days after delivery of
     the Acceptance Notice to the Optionee, the Company and/or its nominee(s)
     shall deliver to the Optionee a check in the amount of the purchase price
     of the Offered Shares to be purchased pursuant to this Section 10, against
     delivery by the Optionee of a certificate or certificates representing the
     Offered Shares to be purchased, duly endorsed for transfer to the Company
     or such nominee(s), as the case may be.  If the Company and/or its

                                       5


     nominee(s) do not elect to purchase all of the Offered Shares, the Optionee
     shall be entitled to sell the balance of the Offered Shares to the
     purchaser(s) named in the Offer Notice at the price specified in the Offer
     Notice or at a higher price and on the terms and conditions set forth in
     the Offer Notice, provided, however, that such sale or other transfer must
     be consummated within sixty (60) days from the date of the Offer Notice and
     any proposed sale after such 60-day period may be made only by again
     complying with the procedures set forth in this Section 10.

          (c) The Optionee may transfer all or any portion of the Shares to a
     trust established for the sole benefit of the Optionee and/or his or her
     spouse or children without such transfer being subject to the right of
     first refusal set forth in this Section 10, provided that the Shares so
     transferred shall remain subject to the terms and conditions of this
     Agreement and no further transfer of such Shares may be made without
     complying with the provisions of this Section 10.

          (d) Any Successor of Optionee pursuant to Section 5 hereof, and any
     transferee of the Shares pursuant to this Section 10, shall hold the Shares
     subject to the terms and conditions of this Agreement and no further
     transfer of the Shares may be made without complying with the provisions of
     this Section 10.

          (e) All stock certificates evidencing the Shares shall be imprinted
     with a legend substantially as follows:

          "THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
          CERTAIN RESTRICTION AGAINST TRANSFER, INCLUDING A RIGHT OF REPURCHASE
          AND A RIGHT OF FIRST REFUSAL IN FAVOR OF THE CORPORATION, AS SET FORTH
          IN A STOCK OPTION AGREEMENT DATED "Date".  TRANSFER OF THESE SHARES
          MAY BE MADE ONLY IN COMPLIANCE WITH THE PROVISIONS OF SAID AGREEMENT,
          A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS
          CORPORATION."

          (f) The rights provided the Company and its nominee(s) under this
     Section 10 shall terminate upon the closing of the initial public offering
     of shares of the Company's Common Stock pursuant to an effective
     registration statement under the Securities Act of 1933, as amended.

     11.  Adjustments Upon Changes in Capital Structure.   In the event that the
          ---------------------------------------------
outstanding shares of Common Stock of the Company are hereafter increased or
decreased or changed into or exchanged for a different number or kind of shares
or other securities of the Company by reason of a recapitalization, stock split,
combination of shares, reclassification, stock dividend or other change in the
capital structure of the Company, then appropriate adjustment shall be made by
the Administrator to the number of Shares subject to the unexercised portion of
this Option and to the Exercise Price per share, in order to preserve, as nearly
as practical, but not to increase, the benefits of the Optionee under this
Option, in accordance with the provisions of Section 4.2 of the Plan.

                                       6


     12.  Mergers, Reorganizations, etc.  In the event that the Company at any
          -----------------------------
time proposes to sell substantially all of its assets, merge into, consolidate
with or to enter into any other reorganization in which the Company is not the
surviving corporation, this Option shall terminate upon the effective date of
such transaction unless provision is made in writing in connection with such
transaction for (a) the assumption of this Option or the substitution of this
Option of a new option or comparable value covering shares of a successor
corporation, with the appropriate adjustments as to the number and kind of
shares and the Exercise Price, in which event this Option or the new option
substituted therefor shall continue in the manner and under the terms so
provided, or (b) the substitution for this Option of a program or plan to
provide rights to Optionee to receive, on exercise of such rights, the type and
amount of consideration Optionee would have received had he or she exercised
this Option prior to such transaction and less the aggregate Exercise Price
therefor.

     13.  No Employment Contract Created.   Neither the granting of this Option
          ------------------------------
nor the exercise hereof shall be construed as granting to the Optionee any right
with respect to continuance of employment by the Company or any of its
subsidiaries.  The right of the Company or any of its subsidiaries to terminate
at will the Optionee's employment at any time (whether by dismissal, discharge
or otherwise), with or without cause, is specifically reserved.

     14.  Rights as Shareholder.   The Optionee (or transferee of this option by
          ---------------------
will or by the laws of descent and distribution) shall have no rights as a
shareholder with respect to any Shares covered by this Option until the date of
the issuance of a stock certificate or certificates to him or her for such
Shares, notwithstanding the exercise of this Option.

     15.  "Market Stand-Off" Agreement.   Optionee agrees that, if requested by
          ----------------------------
the Company or the managing underwriter of any proposed public offering of the
Company's securities, Optionee will not sell or otherwise transfer or dispose of
any Shares held by Optionee without the prior written consent of the Company or
such underwriter, as the case may be, during such period of time, not to exceed
180 days following the effective date of the registration statement filed by the
Company with respect to such offering, as the Company or the underwriter may
specify.

     16.  Interpretation.   This Option is granted pursuant to the terms of the
          --------------
Plan, and shall in all respects be interpreted in accordance therewith.  The
Administrator shall interpret and construe this Option and the Plan, and any
action, decision, interpretation or determination made in good faith by the
Administrator shall be final and binding on the Company and the Optionee.  As
used in this Agreement, the term "Administrator" shall refer to the committee of
                                  -------------
the Board of Directors of the Company appointed to administer the Plan, and if
no such committee has been appointed, the term Administrator shall mean the
Board of Directors.

     17.  Notices.   Any notice, demand or request required or permitted to be
          -------
given under this Agreement shall be in writing and shall be deemed given when
delivered personally or three (3) days after being deposited in the United
States mail, as certified or registered mail, with postage prepaid, and
addressed, if to the Company, at its principal place of business, Attention: the
Chief Financial Officer, and if to the Optionee, at his or her most recent
address as shown in

                                       7


the employment or stock records of the Company.

     18.  Governing Law.   The validity, construction, interpretation, and
          -------------
effect of this Option shall be governed by and determined in accordance with the
laws of the State of California.

     19.  Severability.   Should any provision or portion of this Agreement be
          ------------
held to be unenforceable or invalid for any reason, the remaining provisions and
portions of this Agreement shall be unaffected by such holding.

     20.  Counterparts.   This Agreement may be executed in two or more
          ------------
counterparts, each of which shall be deemed an original and all of which
together shall be deemed one instrument.

     21.  California Corporate Securities Law.   The sale of the shares that are
          -----------------------------------
the subject of this Agreement has not been qualified with the Commissioner of
Corporations of the State of California and the issuance of such shares or the
payment or receipt of any part of the consideration therefor prior to such
qualification is unlawful, unless the sale of such shares is exempt from such
qualification by Sections 25100, 25102 or 25105 of the California Corporate
Securities Law of 1968, as amended.  The rights of all parties to this Agreement
are expressly conditioned upon such qualification being obtained, unless the
sale is so exempt.


     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first above written.

          ---------------

_______ (_____) per share (the "Exercise Price"), subject to the terms and
                                --------------
conditions set forth herein and the provisions of the Plan.  This Option is NOT
intended to qualify as an "incentive stock option" as defined in Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code").
                                                    ----

                            Percentage           Cumulative
        Anniversary          Initially           Percentage

        Fifth                   20%                 100%


     No additional shares shall vest after the date of termination of Optionee's
"Continuous Service" (as defined in Section 3 below), but this Option shall
continue to be exercisable in accordance with Section 3 hereof with respect to
that number of shares that have vested as of the date of termination of
Optionee's Continuous Service; provided, however, if the Optionee shall take a
leave of absence exceeding thirty (30) days which is authorized by the Company
in writing and the Optionee recommences providing services to the Company at the
end of such authorized leave of absence, then the vesting date(s) for any
Option(s) that are unvested at the date of commencement of such leave of absence
shall be extended by the length of such leave of absence.

     3.   Term of Option.   Optionee's right to exercise this Option shall
          --------------
terminate upon the first to occur of the following:

          (a) the expiration of ten (10) years from the date of this Agreement.


          (b) the expiration of thirty (30) days from the date of termination of
     Optionee's Continuous Service if such termination occurs for any reason
     other than permanent disability or death or voluntary resignation:
     provided, however, that if Optionee dies during such thirty-day period the
     provisions of Section 3(d) below shall apply;

          (c) the expiration of one (1) year from the date of termination of
     Optionee's Continuous Service if such termination is due to permanent
     disability of the Optionee (as defined in Section 22(e)(3) of the Code);

          (d) the expiration of one (1) year from the date of termination of
     Optionee's Continuous Service if such termination is due to Optionee's
     death or if death occurs during the thirty-day period following termination
     of Optionee's Continuous Service pursuant to Section 3(b) above; or

          (e) the expiration of ninety (90) days from the date of termination of
     Optionee's Continuous Service if such termination is due to voluntary
     resignation; provided, however that if Optionee dies during such ninety-day
     period the provisions of Section 3(d) above shall apply.

     As used herein, the term "Continuous Service" means (i) employment by
                               ------------------
either the Company or any parent or subsidiary corporation of the Company, or by
a corporation or a parent or subsidiary of a corporation issuing or assuming a
stock option in a transaction to which Section 424(a) of the Code applies, which
is uninterrupted except for vacations, illness (except for permanent disability
as defined in Section 22(e)(3) of the Code), or leaves of absence which are
approved in writing by the Company or any other employer corporations, if
applicable, (ii) service as a member of the Board of Directors of the Company
until Optionee resigns, is removed from office, or Optionee's term of office
expires and he or she is not reelected, or (iii) so long as Optionee is engaged
as a consultant or service provider to the Company or other corporation referred
to in clause (i) above.

     4.   Exercise of Option.   On or after the vesting of any portion of this
          ------------------
Option in accordance with Section 2 above, and until termination of this Option
in accordance with Section 3 above, the portion of this Option which has vested
may be exercised in whole or in part by the Optionee (or, after his or her
death, by the person designated in Section 5 below) upon delivery of the
following to the Company at its principal executive offices:

          (a) a written notice of exercise which identifies this Agreement and
     states the number of Shares then being purchased (but no fractional Shares
     may be purchased).

          (b) a check or cash in the amount of the Exercise Price (or payment of
     the Exercise Price in such other form of lawful consideration as the
     Administrator may approve from time to time under the provisions of Section
     5.3 of the Plan);

          (c) a check or cash in the amount reasonably requested by the Company
     to satisfy the Company's withholding obligations under Federal, State or
     other applicable tax


                                       2


     laws with respect to the taxable income, if any, recognized by the Optionee
     in connection with the exercise of this Option (unless the Company and
     Optionee shall have made other arrangements for deductions or withholding
     from Optionee's wages, bonus or other compensation payable to Optionee, or
     by the withholding of Shares issuable upon exercise of this Option or the
     delivery of Shares owned by the Optionee in accordance with Section 10 of
     the Plan, provided such arrangements satisfy the requirements of applicable
     tax laws); and

          (d) a letter, if requested by the Company, in such form and substance
     as the Company may require, setting forth the investment intent of the
     Optionee, or person designated in Section 5 below, as the case may be.

     5.   Death of Optionee; No Assignment.   The rights of the Optionee under
          --------------------------------
this Agreement may not be assigned or transferred except by will or by the laws
of descent and distribution, and may be exercised during the lifetime of the
Optionee only by such Optionee.  Any attempt to sell, pledge, assign,
hypothecate, transfer or dispose of this Option in contravention of this
Agreement or the Plan shall be void and shall have no effect.  If the Optionee's
Continuous Service terminates as a result of his or her death, and provided
Optionee's rights hereunder shall have vested pursuant to Section 2 hereof,
Optionee's legal representative, his or her legatee, or the person who acquired
the right to exercise this Option by reason of the death of the Optionee
(individually, a "Successor") shall succeed to the Optionee's rights and
                  ---------
obligations under this Agreement.  After the death of the Optionee, only a
Successor may exercise this Option.

     6.   Representations and Warranties of Optionee.
          ------------------------------------------

          (a) Optionee represents and warrants that this Option is being
     acquired by Optionee for Optionee's personal account, for investment
     purposes only, and not with a view to the distribution, resale or other
     disposition thereof.

          (b) Optionee acknowledges that the Company may issue Shares upon the
     exercise of the Option without registering such Shares under the Securities
     Act of 1933, as amended (the "Act"), on the basis of certain exemptions
                                   ---
     from such registration requirement.  Accordingly, Optionee agrees that his
     or her exercise of the Option may be expressly conditioned upon his or her
     delivery to the Company of an investment certificate including such
     representations and undertakings as the Company may reasonably require in
     order to assure the availability of such exemptions, including a
     representation that Optionee is acquiring the Shares for investment and not
     with a present intention of selling or otherwise disposing thereof and an
     agreement by Optionee that the certificates evidencing the Shares may bear
     a legend indicating such non-registration under the Act and the resulting
     restrictions on transfer.  Optionee acknowledges that, because Shares
     received upon exercise of an Option may be unregistered, Optionee may be
     required to hold the Shares indefinitely unless they are subsequently
     registered for resale under the Act or an exemption from such registration
     is available.

          (c) Optionee acknowledges receipt of a copy of the Plan and
     understands that


                                       3


     all rights and obligations connected with this Option are set forth in this
     Agreement and in the Plan.

     7.   Restrictive Legends.   Optionee hereby acknowledges that Federal
          -------------------
securities laws and the securities laws of the State in which he or she resides
may require the placement of certain restrictive legends upon the Shares issued
upon exercise of this Option, and Optionee hereby consents to the placing of any
such legends upon certificates evidencing the Shares as the Company, or its
counsel, may deem necessary or advisable.

     8.   Limitation of Company's Liability for Nonissuance.   The Company
          -------------------------------------------------
agrees to use its reasonable best efforts to obtain from any applicable
regulatory agency such authority or approval as may be required in order to
issue and sell the Shares to the Optionee pursuant to this Option.  Inability of
the Company to obtain, from any such regulatory agency, authority or approval
deemed by the Company's counsel to be necessary for the lawful issuance and sale
of the Shares hereunder and under the Plan shall relieve the Company of any
liability in respect of the nonissuance or sale of such shares as to which such
requisite authority or approval shall not have been obtained.

     9.   Call Option.
          -----------

          (a) Upon the termination of the Optionee's Continuous Service for any
     reason, including, without limitation, death or permanent disability,
     voluntary termination or involuntary termination without cause (or in the
     event Optionee is a transferee if original Optionee's Continuous Service
     terminates), the Company shall have the right to purchase for cash all or
     any portion of the Shares acquired pursuant to the exercise of this Option
     which are held by Optionee (the "Purchased Shares").
                                      ----------------

          (b) The Company may purchase all or any portion of such Purchased
     Shares at a per Share price equal to the greater of (i) the Fair Market
     Value of such shares as defined in the Plan and (ii) the original purchase
     price paid by Purchaser, plus one percent (1%) per month on a cumulative,
     compound basis.

          (c) Any Call Option may be exercised by delivery of written notice
     thereof (the "Call Notice") to Optionee within sixty (60) days of the later
                   -----------
     of (i) the Termination Date or (ii) the dates of exercise of the option to
     which the Purchased Shares relate (the "Call Option Exercise Period").  The
                                             ---------------------------
     Call Notice shall state that the Company has elected to exercise the Call
     Option, and the number and price of the Purchased Shares with respect to
     which the Call Option is being exercised.

          (d) The closing of any purchase of Purchased Shares pursuant to the
     exercise of the Call Option pursuant to this paragraph 9 shall take place
     as soon as reasonably practicable and in no event later than ten (10) days
     after termination of the applicable Call Option Exercise Period at the
     principal office of the Company, or at such other time and location as the
     parties to such purchase may mutually determine.  At the closing of any
     purchase and sale of Purchased Shares pursuant to this Paragraph 9,
     Optionee shall deliver to the Company a certificate or certificates
     representing the Purchased Shares to


                                       4


     be purchased by the Company duly endorsed, or with stock powers duly
     endorsed, for transfer with signature guaranteed, free and clear of any
     lien or encumbrance, with any necessary stock transfer tax stamps affixed,
     and the Company shall pay to Optionee the purchase price of the Purchased
     Shares being purchased by the Company. The delivery of a certificate or
     certificates for Purchased Shares by any Person selling Purchased Shares
     pursuant to this Paragraph 9 shall be deemed a representation and warranty
     by such Person that: (i) such Person has full right, title and interest in
     and to such Purchased Shares; (ii) such Person has all necessary power and
     authority and has taken all necessary action to sell such Purchased Shares
     as contemplated; and (iii) such Purchased Shares are free and clear of any
     and all liens or encumbrances.

          (e) The provisions of this Paragraph 9 shall automatically terminate
     upon the earlier to occur of (i) in the event that the Company sells
     substantially all of its assets, merges into, consolidates with or enters
     into any other reorganization (including the sale of substantially all of
     its assets) in which the Company is not the surviving corporation (other
     than one in which 50% or more of the outstanding capital stock of the
     surviving corporation is held by the Company's current stockholders), or if
     the Company is the surviving corporation and ownership of the outstanding
     capital stock of the Company following the transaction changes by 50% or
     more as a result of such transaction, or (ii) on the date of closing of an
     initial public offering registered on Form S-1 (or any successor form)
     under the Act of securities of the Company.

     10.  Right of First Refusal.
          ----------------------

          (a) The Purchased Shares, as defined above, acquired pursuant to the
     exercise of this Option may be sold by the Optionee only in compliance with
     the provisions of this Section 10, and subject in all cases to compliance
     with the provisions of Section 6(b) hereof.  Prior to any intended sale,
     Optionee shall first give written notice (the "Offer Notice") to the
                                                    ------------
     Company specifying (i) his or her bona fide intention to sell or otherwise
     transfer such Shares, (ii) the name and address of the proposed
     purchaser(s), (iii) the number of Shares the Optionee proposes to sell (the
     "Offered Shares"), (iv) the price for which he or she proposes to sell the
      --------------
     Offered Shares, and (v) all other material terms and conditions of the
     proposed sale.

          (b) Within thirty (30) days after receipt of the Offer Notice, the
     Company or its nominee(s) may elect to purchase all or any portion of the
     Offered Shares at the price and on the terms and conditions set forth in
     the Offer Notice by delivery of written notice (the "Acceptance Notice") to
                                                          -----------------
     the Optionee specifying the number of Offered Shares that the Company or
     its nominees elect to purchase.  Within fifteen (15) days after delivery of
     the Acceptance Notice to the Optionee, the Company and/or its nominee(s)
     shall deliver to the Optionee a check in the amount of the purchase price
     of the Offered Shares to be purchased pursuant to this Section 10, against
     delivery by the Optionee of a certificate or certificates representing the
     Offered Shares to be purchased, duly endorsed for transfer to the Company
     or such nominee(s), as the case may be.  If the Company and/or its
     nominee(s) do not elect to purchase all of the Offered Shares, the Optionee
     shall be entitled to sell the balance of the Offered Shares to the
     purchaser(s) named in the Offer Notice at the price specified in the Offer


                                       5


     Notice or at a higher price and on the terms and conditions set forth in
     the Offer Notice, provided, however, that such sale or other transfer must
     be consummated within sixty (60) days from the date of the Offer Notice and
     any proposed sale after such 60-day period may be made only by again
     complying with the procedures set forth in this Section 10.

          (c) The Optionee may transfer all or any portion of the Shares to a
     trust established for the sole benefit of the Optionee and/or his or her
     spouse or children without such transfer being subject to the right of
     first refusal set forth in this Section 10, provided that the Shares so
     transferred shall remain subject to the terms and conditions of this
     Agreement and no further transfer of such Shares may be made without
     complying with the provisions of this Section 10.

          (d) Any Successor of Optionee pursuant to Section 5 hereof, and any
     transferee of the Shares pursuant to this Section 10, shall hold the Shares
     subject to the terms and conditions of this Agreement and no further
     transfer of the Shares may be made without complying with the provisions of
     this Section 10.

          (e) All stock certificates evidencing the Shares shall be imprinted
     with a legend substantially as follows:

          "THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
          CERTAIN RESTRICTION AGAINST TRANSFER, INCLUDING A RIGHT OF REPURCHASE
          AND A RIGHT OF FIRST REFUSAL IN FAVOR OF THE CORPORATION, AS SET FORTH
          IN A STOCK OPTION AGREEMENT DATED "Date".  TRANSFER OF THESE SHARES
          MAY BE MADE ONLY IN COMPLIANCE WITH THE PROVISIONS OF SAID AGREEMENT,
          A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS
          CORPORATION."

          (f) The rights provided the Company and its nominee(s) under this
     Section 10 shall terminate upon the closing of the initial public offering
     of shares of the Company's Common Stock pursuant to an effective
     registration statement under the Securities Act of 1933, as amended.

     11.  Adjustments Upon Changes in Capital Structure.   In the event that the
          ---------------------------------------------
outstanding shares of Common Stock of the Company are hereafter increased or
decreased or changed into or exchanged for a different number or kind of shares
or other securities of the Company by reason of a recapitalization, stock split,
combination of shares, reclassification, stock dividend or other change in the
capital structure of the Company, then appropriate adjustment shall be made by
the Administrator to the number of Shares subject to the unexercised portion of
this Option and to the Exercise Price per share, in order to preserve, as nearly
as practical, but not to increase, the benefits of the Optionee under this
Option, in accordance with the provisions of Section 4.2 of the Plan.

     12.  Mergers, Reorganizations, etc.  In the event that the Company at any
          -----------------------------
time


                                       6


proposes to sell substantially all of its assets, merge into, consolidate
with or to enter into any other reorganization in which the Company is not the
surviving corporation, this Option shall terminate upon the effective date of
such transaction unless provision is made in writing in connection with such
transaction for (a) the assumption of this Option or the substitution of this
Option of a new option or comparable value covering shares of a successor
corporation, with the appropriate adjustments as to the number and kind of
shares and the Exercise Price, in which event this Option or the new option
substituted therefor shall continue in the manner and under the terms so
provided, or (b) the substitution for this Option of a program or plan to
provide rights to Optionee to receive, on exercise of such rights, the type and
amount of consideration Optionee would have received had he or she exercised
this Option prior to such transaction and less the aggregate Exercise Price
therefor.

     13.  No Employment Contract Created.   Neither the granting of this Option
          ------------------------------
nor the exercise hereof shall be construed as granting to the Optionee any right
with respect to continuance of employment by the Company or any of its
subsidiaries.  The right of the Company or any of its subsidiaries to terminate
at will the Optionee's employment at any time (whether by dismissal, discharge
or otherwise), with or without cause, is specifically reserved.

     14.  Rights as Shareholder.   The Optionee (or transferee of this option by
          ---------------------
will or by the laws of descent and distribution) shall have no rights as a
shareholder with respect to any Shares covered by this Option until the date of
the issuance of a stock certificate or certificates to him or her for such
Shares, notwithstanding the exercise of this Option.

     15.  "Market Stand-Off" Agreement.   Optionee agrees that, if requested by
          ----------------------------
the Company or the managing underwriter of any proposed public offering of the
Company's securities, Optionee will not sell or otherwise transfer or dispose of
any Shares held by Optionee without the prior written consent of the Company or
such underwriter, as the case may be, during such period of time, not to exceed
180 days following the effective date of the registration statement filed by the
Company with respect to such offering, as the Company or the underwriter may
specify.

     16.  Interpretation.   This Option is granted pursuant to the terms of the
          --------------
Plan, and shall in all respects be interpreted in accordance therewith.  The
Administrator shall interpret and construe this Option and the Plan, and any
action, decision, interpretation or determination made in good faith by the
Administrator shall be final and binding on the Company and the Optionee.  As
used in this Agreement, the term "Administrator" shall refer to the committee of
                                  -------------
the Board of Directors of the Company appointed to administer the Plan, and if
no such committee has been appointed, the term Administrator shall mean the
Board of Directors.

     17.  Notices.   Any notice, demand or request required or permitted to be
          -------
given under this Agreement shall be in writing and shall be deemed given when
delivered personally or three (3) days after being deposited in the United
States mail, as certified or registered mail, with postage prepaid, and
addressed, if to the Company, at its principal place of business, Attention: the
Chief Financial Officer, and if to the Optionee, at his or her most recent
address as shown in the employment or stock records of the Company.

          -------------
effect of this Option shall be governed by and determined in accordance with the
laws of the State of California.

     19.  Severability.   Should any provision or portion of this Agreement be
          ------------
held to be unenforceable or invalid for any reason, the remaining provisions and
portions of this Agreement shall be unaffected by such holding.

     20.  Counterparts.   This Agreement may be executed in two or more
          ------------
counterparts, each of which shall be deemed an original and all of which
together shall be deemed one instrument.

     21.  California Corporate Securities Law.   The sale of the shares that are
          -----------------------------------
the subject of this Agreement has not been qualified with the Commissioner of
Corporations of the State of California and the issuance of such shares or the
payment or receipt of any part of the consideration therefor prior to such
qualification is unlawful, unless the sale of such shares is exempt from such
qualification by Sections 25100, 25102 or 25105 of the California Corporate
Securities Law of 1968, as amended.  The rights of all parties to this Agreement
are expressly conditioned upon such qualification being obtained, unless the
sale is so exempt.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first above written.
