                                        2

<PAGE>

          b. Payment of Option Price. Subject to paragraph 3 below, your Option
     may be exercised in whole or in part upon payment of an amount (the "Option
     Price") equal to the product of (i) the Exercise Price multiplied by (ii)
     the number of Option Shares to be acquired. Payment shall be made in cash
     (including check, bank draft or money order).

          3. Exercisability/Vesting.

          a. Normal Vesting. [Your Option shall fully vest and become
     exercisable with respect to all of your Option Shares at the time such
     Option is granted to you. None of your Option Shares shall be vested as of
     the date your relationship as a Service Provider with the Company began.
     Notwithstanding the foregoing,] Your Option Shares shall become vested in
     accordance with the following schedule: [25% of your Option Shares or, if
     greater, 25% of the Option Shares you would hold assuming the full exercise
     of your Option (rounded down to the nearest whole share) shall vest one
     year after ________________ and 2 and 1/12% of your Option Shares or, if
     greater, 2 and 1/12% of the Option Shares you would hold assuming the full
     exercise of your Option (rounded down to the nearest whole share) shall
     vest at the end of each calendar month beginning one year after
     _____________________ and continuing for 36 months][2 and 1/12% of your
     Option Shares or, if greater, 2 and 1/12% of the Option Shares you would
     hold assuming the full exercise of your option (rounded to the nearest
     whole share) shall vest at the end of each calendar month after the date
     your relationship as a Service Provider began] [(thereby totaling a four
     year vesting schedule)] if and only if you are, and have been, continuously
     employed by the Company [or acting as a Service Provider] from the date of
     this Agreement through such date; provided that none of your Option Shares
     shall be vested in the event that your employment with the Company [or your
     relationship as a Service Provider] terminates for any reason prior to the
     first anniversary of the [your employment with][date your relationship as a
     Service Provider to] the Company began. Option Shares which have become
     vested pursuant to the terms of this Agreement are referred to herein as
     "Vested Option Shares," and all other Options are referred to herein as
     "Unvested Option Shares."

          b. Acceleration of Vesting on Sale of the Company. If you have been
     continuously employed by the Company [or have been acting as a Service
     Provider] from the date of this Agreement until a Sale of the Company, the
     portion of your outstanding Option Shares which have not become vested at
     the date of such event shall immediately vest and become exercisable with
     respect to 25% of your Unvested Option Shares (or, if greater, 25% of the
     Unvested Option Shares you would hold assuming the full exercise of your
     Options) simultaneously with the consummation of the Sale of the Company.
     [If following a Sale of the Company, you are either involuntarily
     terminated for reasons other than Cause, or you voluntarily terminate your
     employment because (i) your responsibilities have been materially reduced
     or (ii) your cash compensation plan has been reduced by 10% or more, 100%
     of your Unvested Option Shares (or, if greater, 100% of the Unvested Option
     Shares you would hold assuming the full exercise of your Options) shall
     immediately vest upon your termination date.] In any event, any portion of
     your Option which has not been exercised prior to, or in connection with,
     the Sale of the Company shall be forfeited, unless otherwise determined by
     the Committee or the Board.

          4. Expiration of Option.

          a. Normal Expiration. In no event shall any part of your Option be
     exercisable after the Expiration Date set forth in paragraph 2(a) above.

          b. Early Expiration Upon Termination of Employment or Service Provider


                                        3

<PAGE>

     Relationship. Any portion of your Option that was not vested and
     exercisable on the date your employment or Service Provider relationship
     with the Company is terminated shall expire and be forfeited on such date,
     and any portion of your Option that was vested and exercisable on the date
     your employment or Service Provider relationship with the Company
     terminated shall also expire and be forfeited; provided that: (i) if you
     die or become subject to any Disability, the portion of your Option that is
     vested and exercisable shall expire 180 days from the date of your death or
     Disability, but in no event after the Expiration Date, and (ii) if you
     retire, resign or are discharged by the Company other than for Cause, the
     portion of your Option that is vested and exercisable shall expire 90 days
     from the date of your resignation or discharge, but in no event after the
     Expiration Date.

          5. Procedure for Exercise. You may exercise all or any portion of your
Option, at any time and from time to time prior to its expiration, by delivering
written notice to the Company (to the attention of the Company's Secretary) and
your written acknowledgment that you have read and have been afforded an
opportunity to ask questions of management of the Company regarding all
financial and other information provided to you regarding the Company, together
with payment of the Option Price in accordance with the provisions of paragraph
2(b) above. As a condition to any exercise of your Option, you shall permit the
Company to deliver to you all financial and other information regarding the
Company it believes necessary to enable you to make an informed investment
decision, and you shall make all customary investment representations which the
Company requires.

You understand that you will be solely responsible for any necessary or
desirable filings you may wish to make upon the exercise of your Options
(including, without limitation, filing an 83(b) election under the Code) and
that the Company will not be responsible for making such filings on your behalf.

          6. Securities Laws Restrictions and Other Restrictions on Transfer of
Option Shares. You represent that when you exercise your Option you shall be
purchasing Option Shares for your own account and not on behalf of others. You
understand and acknowledge that federal and state securities laws govern and
restrict your right to offer, sell or otherwise dispose of any Option Shares
unless your offer, sale or other disposition thereof is registered under the
Securities Act and state securities laws, or in the opinion of the Company's
counsel, such offer, sale or other disposition is exempt from registration or
qualification thereunder. You agree that you shall not offer, sell or otherwise
dispose of any Option Shares in any manner which would: (i) require the Company
to file any registration statement with the Securities and Exchange Commission
(or any similar filing under state law) or to amend or supplement any such
filing or (ii) violate or cause the Company to violate the Securities Act, the
rules and regulations promulgated thereunder or any other state or federal law.
You further understand that the certificates for any Option Shares you purchase
shall bear such legends as the Company deems necessary or desirable in
connection with the Securities Act or other rules, regulations or laws.

          7. Non-Transferability of Option. Your Option is personal to you and
is not transferable by you other than by will or the laws of descent and
distribution. During your lifetime only you (or your guardian or legal
representative) may exercise your Option. In the event of your death, your
Option may be exercised only (i) by the executor or administrator of your estate
or the


                                        4

<PAGE>

person or persons to whom your rights under the Option shall pass by will or the
laws of descent and distribution and (ii) to the extent that you were entitled
hereunder at the date of your death.

          8. Conformity with Plan. Your Option is intended to conform in all
respects with, and is subject to all applicable provisions of, the Plan (which
is incorporated herein by reference). Inconsistencies between this Agreement
and the Plan shall be resolved in accordance with the terms of the Plan. By
executing and returning the enclosed copy of this Agreement, you acknowledge
your receipt of this Agreement and the Plan and agree to be bound by all of the
terms of this Agreement and the Plan.

          9. Rights of Participants. Nothing in this Agreement shall interfere
with or limit in any way the right of the Company to terminate your employment
or relationship as a Service Provider at any time (with or without Cause), nor
confer upon you any right to continue in the employ of the Company or as a
Service Provider for any period of time or to continue your present (or any
other) rate of compensation, and in the event of your termination of employment
or relationship as a Service Provider (including, but not limited to,
termination by the Company without Cause) any portion of your Option that was
not previously vested and exercisable shall be forfeited. Nothing in this
Agreement shall confer upon you any right to be selected again as a Plan
participant, and nothing in the Plan or this Agreement shall provide for any
adjustment to the number of Option Shares subject to your Option upon the
occurrence of subsequent events except as provided in paragraph 11 below.

          10. Withholding of Taxes. The Company shall be entitled, if necessary
or desirable, to withhold from you from any amounts due and payable by the
Company to you (or secure payment from you in lieu of withholding) the amount of
any withholding or other tax due from the Company with respect to any Option
Shares issuable under this Plan, and the Company may defer such issuance unless
indemnified by you to its satisfaction.

          11. Adjustments. In the event of a reorganization, recapitalization,
stock dividend or stock split, reclassification or combination or other change
in the shares of Common Stock, the Board or the Committee may, in order to
prevent the dilution or enlargement of rights under your Option, make such
adjustments in the number and type of shares authorized by the Plan, the number
and type of shares covered by your Option and the Exercise Price specified
herein as may be determined to be appropriate and equitable.

          12. Right to Purchase Unvested Option Shares Upon Your Termination of
Service Provider Relationship.

          a. Repurchase of Unvested Option Shares. If your employment or
     relationship as a Service Provider with the Company shall terminate,
     including upon your death, Disability, resignation or termination with or
     without Cause (the date on which such termination occurs being referred to
     as the "Termination Date"), then the Company shall have the option to
     repurchase all or any part of the Unvested Option Shares issued or issuable
     upon exercise of your Option, whether held by you or by one or more of your
     transferees, at the price determined in accordance with the provisions of
     paragraph 13 hereof (the "Repurchase Option").


                                        5

<PAGE>

          b. Repurchase by Company. The Company may elect to purchase all or any
     portion of the Unvested Option Shares by delivery of written notice (the
     "Repurchase Notice") to you or any other holders of the Option Shares
     within 120 days after the Termination Date. The Repurchase Notice shall set
     forth the number of Option Shares to be acquired from you and such other
     holder(s), the aggregate consideration to be paid for such shares and the
     time and place for the closing of the transaction. The number of Option
     Shares to be repurchased by the Company shall first be satisfied to the
     extent possible from the Unvested Option Shares held by you at the time of
     delivery of the Repurchase Notice. If the number of Option Shares then held
     by you is less than the total number of Option Shares the Company has
     elected to purchase, then the Company shall purchase the remaining shares
     elected to be purchased from the other holders thereof, pro rata according
     to the number of shares held by each such holder at the time of delivery of
     such Repurchase Notice (determined as close as practical to the nearest
     whole shares).

          c. Closing of Repurchase of Unvested Option Shares. The purchase of
     Option Shares pursuant to this paragraph 12 shall be closed at the
     Company's executive offices within 20 days after the expiration of the
     120-day period referred to in paragraph 12(b). At the closing, the
     purchaser or purchasers shall pay the purchase price in the manner
     specified in paragraph 13(b) and you and any other holders of Option Shares
     being purchased shall deliver the certificate or certificates representing
     such shares to the purchaser or purchasers or their nominees, accompanied
     by duly executed stock powers. Any purchaser of Option Shares under this
     paragraph 12 shall be entitled to receive customary representations and
     warranties from you and any other selling holders of Option Shares
     regarding the sale of such shares (including representations and warranties
     regarding good title to such shares, free and clear of any liens or
     encumbrances) and to require all sellers' signatures to be guaranteed by a
     national bank or reputable securities broker.

          13. Purchase Price for Option Shares.

          a. Purchase Price. The purchase price per share to be paid for the
     Option Shares purchased by the Company pursuant to paragraph 12 shall for
     Unvested Option Shares be equal to the Exercise Price for each such Option
     Share.

          b. Manner of Payment. If the Company elects to purchase all or any
     part of the Option Shares, including Option Shares held by one or more
     transferees, the Company shall pay for such shares: (i) first, by certified
     check or wire transfer of funds to the extent such payment would not cause
     the Company to violate the General Corporation Law of the State of Delaware
     and would not cause the Company to breach any agreement to which it is a
     party relating to the indebtedness for borrowed money or other material
     agreement; and (ii) thereafter, with a subordinated promissory note of the
     Company. Such subordinated promissory note shall bear interest at the rate
     of 8% per annum (which shall be payable annually in cash unless otherwise
     prohibited), shall have all principal payment due on the fifth anniversary
     of the date of issuance and shall be subordinated on terms and conditions
     satisfactory to the holders of the Company's indebtedness for borrowed
     money. In addition, the Company may pay the purchase price for such shares
     by offsetting amounts outstanding under any indebtedness or obligations
     owed by you to the Company.

          14. Restrictions on Transfer of Option Shares.

          a. Transfer of Option Shares. You shall not sell, pledge or otherwise
     transfer any interest in any Option Shares except pursuant to a Public Sale
     or the provisions of paragraph 12 or 16 hereof ("Exempt Transfers").

          b. Certain Permitted Transfers. The restrictions contained in this
     paragraph 14 shall not apply with respect to transfers of Option Shares (i)
     pursuant to applicable laws of descent and distribution or (ii) among your
     family group; provided that the restrictions contained in this paragraph 14
     shall continue to be applicable to the Option Shares after any such
     transfer and the transferees of such Option Shares have agreed in writing
     to be bound by the provisions of this Agreement. Your "family group" means
     your spouse and descendants.

          c. Termination of Restrictions. The restrictions on the transfer of
     Option Shares set forth in this paragraph 14 shall continue with respect to
     each Option Share until the date on which such Option Share has been
     transferred in a transaction permitted by this paragraph 14(c) (except in a
     transaction contemplated by paragraph 14(b)); provided in any event the
     restrictions on transfers set forth in this paragraph 14 shall terminate
     when the Company has sold shares of its Common Stock pursuant to a public
     offering registered under the Securities Act.

          15. Additional Restrictions on Transfer.

          a. Restrictive Legend. The certificates representing the Option Shares
     shall bear the following legend:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED ON
     [________], HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE "ACT"), OR UNDER ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD
     OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER
     THE ACT AND APPLICABLE STATE SECURITIES LAWS OR AN EXEMPTION FROM
     REGISTRATION THEREUNDER. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
     ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE
     OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN AN OPTION AGREEMENT
     BETWEEN THE COMPANY AND [________] DATED AS OF [________] A COPY OF WHICH
     MAY BE OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF
     BUSINESS WITHOUT CHARGE."

          b. Opinion of Counsel. You may not sell, transfer or dispose of any
     Option Shares (except pursuant to an effective registration statement under
     the Securities Act) without first delivering to the Company an opinion of
     counsel reasonably acceptable in form and substance to the Company that
     registration under the Securities Act or any applicable state securities
     law is not required in connection with such transfer.


                                        7

<PAGE>

          c. Holdback. You agree not to effect any public sale or distribution
     of any equity securities of the Company, or any securities convertible into
     or exchangeable or exercisable for such securities, during the seven days
     prior to and the 180 days after the effectiveness of any underwritten
     Demand Registration or any underwritten Piggyback Registration (as such
     terms are defined in the Registration Agreement), except as part of such
     underwritten registration if otherwise permitted.

          16. Sale of the Company.

          a. Consent to Sale of Company. If the Board or the holders of a
     majority of the common stock then outstanding approve a Sale of the Company
     (an "Approved Sale"), you shall vote for, consent to, and raise no
     objections against the Approved Sale of the Company. If the Approved Sale
     is structured (i) as a merger or consolidation, you shall waive any
     dissenter's rights, appraisal rights or similar rights in connection with
     such merger or consolidation, or (ii) as a sale of stock, you shall agree
     to sell all of your Option Shares, rights to acquire Option Shares and
     other shares of the Company's capital stock on the terms and conditions
     approved by the Persons approving such sale. You shall take all necessary
     and desirable actions in connection with the consummation of the Approved
     Sale of the Company as requested by the Board.

          b. Purchaser Representative. If the Company or the holders of the
     Company's securities enter into any negotiation or transaction for which
     Rule 506 (or any similar rule then in effect) promulgated by the Securities
     Exchange Commission may be available with respect to such negotiation or
     transaction (including a merger, consolidation or other reorganization),
     you shall, at the request of the Company, appoint a purchaser
     representative (as such term is defined in Rule 501) reasonably acceptable
     to the Company. If you appoint the purchaser representative designated by
     the Company, the Company shall pay the fees of such purchaser
     representative, but if you decline to appoint the purchaser representative
     designated by the Company you shall appoint another purchaser
     representative (reasonably acceptable to the Company), and you shall be
     responsible for the fees of the purchaser representative so appointed.

          c. Termination of Restrictions. The provisions of this paragraph 16
     shall terminate when the Company has sold shares of its Common Stock
     pursuant to a public offering registered under the Securities Act.

          17. Remedies. The parties hereto shall be entitled to enforce their
rights under this Agreement specifically, to recover damages by reason of any
breach of any provision of this Agreement and to exercise all other rights
existing in their favor. You acknowledge and agree that money damages would not
be an adequate remedy for any breach by you of the provisions of this Agreement
and that the Company may, in its sole discretion, apply to any court of law or
equity of competent jurisdiction for specific performance and/or injunctive
relief (without posting bond or other security) in order to enforce or prevent
any violation by you of the provisions of this Agreement.

you and the Company.

          19. Successors and Assigns. Except as otherwise expressly provided

of any of the parties hereto shall bind and inure to the benefit of the
respective successors and permitted assigns of the parties hereto whether so
expressed or not.

          20. Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

          21. Counterparts. This Agreement may be executed simultaneously in two
or more counterparts, each of which shall constitute an original, but all of
which taken together shall constitute one and the same Agreement.
