                 TERMS AND CONDITIONS OF INCENTIVE STOCK OPTION

1.       VESTING; LIMITS ON EXERCISE.

         As set forth on the cover page of this Option Agreement, the Option
shall vest in percentage installments of the aggregate number of shares of
Common Stock subject to the Option.

         -    Cumulative Exercisability. The Participant has the right to
              exercise the Option (to the extent not previously exercised), and
              such right shall continue, until the expiration or earlier
              termination of the Option.

         -    No Fractional Shares. Fractional share interests shall be
              disregarded, but may be cumulated.

         -    Minimum Exercise. No fewer than 1001 shares of Common Stock may be
              purchased at any one time, unless the number purchased is the
              total number at the time exercisable under the Option.

         -    ISO Value Limit. If the aggregate fair market value of the shares
              with respect to which ISOs (whether granted under the Option or
              otherwise) first become exercisable by the Participant in any
              calendar year exceeds $100,000, as measured on the applicable
              Award Dates, the limitations of Section 2.4.1 of the Plan shall
              apply and to such extent the Option will be rendered a
              Nonqualified Stock Option.

2.       CONTINUANCE OF EMPLOYMENT/SERVICE REQUIRED; NO EMPLOYMENT/SERVICE
         COMMITMENT.

         The vesting schedule requires continued employment or service through
each applicable vesting date as a condition to the vesting of the applicable
installment of the Option and the rights and benefits under this Option
Agreement. Partial employment or service, even if substantial, during any
vesting period will not entitle the Participant to any proportionate vesting or
avoid or mitigate a termination of rights and benefits upon or following a
termination of employment or services as provided in Section 4 below, under the
Plan, or under the applicable Exercise Agreement (as such term is defined
below).

         Nothing contained in this Option Agreement, the Plan, or any Exercise
Agreement constitutes an employment or service commitment by the Company,
affects the Participant's status, if he or she is an employee, as an employee at
will who is subject to termination without cause, confers upon the Participant
any right to remain employed by or in service to the Company or any Subsidiary,
interferes in any way with the right of the Company or any Subsidiary at any
time to terminate such employment or service, or affects the right of the
Company or any Subsidiary to increase or decrease the Participant's other
compensation.

3.       METHOD OF EXERCISE OF OPTION.

         To the extent that the Participant desires to exercise a portion of the
Option that is then vested, the Participant shall deliver to the Corporation an
executed Exercise Agreement in substantially the form attached hereto as Exhibit
A and satisfy the other exercise procedures described below. The Participant
also has the right, until the date that is ninety (90) days after the Award Date
(the "UNVESTED EXERCISE DEADLINE"), to exercise the unvested portion of the
Option. After the Unvested Exercise Deadline, the Option may only be exercised
to the extent that it is then vested. To the extent that the Participant desires
to exercise a portion of the Option that is not

                                       1
<PAGE>

vested, the Participant shall deliver to the Corporation, on or before the
Unvested Exercise Deadline, an executed Exercise Agreement in substantially the
form attached hereto as Exhibit B and satisfy the other exercise procedures
described below. The applicable form of Exercise Agreement is referred to as the
"EXERCISE AGREEMENT."

         The Option is exercisable (whether the exercise is with respect to the
vested or the unvested portion of the Option, as described above) by the
delivery to the Secretary of the Corporation of a written notice stating the
number of shares of Common Stock to be purchased pursuant to the Option and
accompanied by:

         -    delivery of an executed Exercise Agreement in substantially the
              form attached hereto as Exhibit A or Exhibit B, as applicable (see
              the Exercise Agreement discussion above), or such other form as
              the Committee may require from time to time;

         -    delivery of an executed Securityholders Agreement in substantially
              the form attached hereto as Exhibit C or such other form as the
              Committee may require from time to time (the "SECURITYHOLDERS
              AGREEMENT");

         -    payment in full for the Exercise Price of the shares to be
              purchased, in cash or by electronic funds transfer to the
              Corporation, or by certified or cashier's check payable to the
              order of the Corporation subject to such specific procedures or
              directions as the Committee may establish;

         -    satisfaction of the tax withholding provisions of Section 4.4 of
              the Plan; and

         -    any written statements or agreements required pursuant to Section
              4.3 of the Plan.

The Committee also may, but is not required to, authorize a non-cash payment
alternative specified below at or prior to the time of exercise. In which case,
the Exercise Price and/or applicable withholding taxes, to the extent so
authorized, may be paid in full or in part by delivery to the Corporation of:

         -    shares of Common Stock already owned by the Participant, valued at
              their Fair Market Value on the exercise date, provided, however,
              that any shares acquired directly from the Corporation (upon
              exercise of a stock option or otherwise) must have been owned by
              the Participant for at least six (6) months before they can be
              used in connection with an exercise of the Option; and/or

         -    a note meeting the requirements of Section 1.6 of the Plan (or, in
              the case of tax loans, Section 4.4.2 of the Plan).

4.       EARLY TERMINATION OF OPTION.

         The Option, to the extent not previously exercised, and all other
rights in respect thereof, whether vested and exercisable or not, shall
terminate and become null and void prior to the Expiration Date in the event of:

         -    the termination of the Participant's employment or services as
              provided in Section 2.6 of the Plan, or

         -    the termination of the Option pursuant to Section 4.2 of the Plan.

                                       2
<PAGE>

         Notwithstanding any post-termination exercise period provided for
herein or in the Plan, the Option will qualify as an ISO only if it is exercised
within the applicable exercise periods for ISOs under, and meets all of the
other requirements of, the Code. If the Option is not exercised within the
applicable exercise periods for ISOs or does not meet such other requirements,
the Option will be rendered a Nonqualified Stock Option.

5.       NON-TRANSFERABILITY AND OTHER RESTRICTIONS.

         The Option and any other rights of the Participant under this Option
Agreement or the Plan are nontransferable and exercisable only by the
Participant, except as set forth in Section 1.5 of the Plan. Any shares of
Common Stock issued on exercise of the Option are subject to substantial
restrictions on transfer, and are subject to rights in favor of the Corporation
as set forth herein, in the Securityholders Agreement, and in the applicable
Exercise Agreement.

6.       SECURITIES LAW COMPLIANCE.

         The Participant acknowledges that the Option and the shares of Common
Stock are not being registered under the Securities Act, based, in part, in
reliance upon an exemption from registration under Securities and Exchange
Commission Rule 701 promulgated under the Securities Act of 1933, and a
comparable exemption from qualification under the California Corporate
Securities Law, as each may be amended from time to time. The Participant, by
executing this Option Agreement, hereby makes the following representations to
the Corporation and acknowledges that the Corporation's reliance on federal and
state securities law exemptions from registration and qualification is
predicated, in substantial part, upon the accuracy of these representations:

     -   The Participant is acquiring the Option and, if and when he/she
         exercises the Option, will acquire the shares of Common Stock solely
         for the Participant's own account, for investment purposes only, and
         not with a view to or an intent to sell, or to offer for resale in
         connection with any unregistered distribution, all or any portion of
         the shares within the meaning of the Securities Act, the California
         Corporate Securities Law, or other applicable state securities laws.

     -   The Participant has had an opportunity to ask questions and receive
         answers from the Corporation regarding the terms and conditions of the
         Option and the restrictions imposed on any shares of Common Stock
         purchased upon exercise of the Option. The Participant has been
         furnished with, and/or has access to, such information as he or she
         considers necessary or appropriate for deciding whether to exercise the
         Option and purchase shares of Common Stock. However, in evaluating the
         merits and risks of an investment in the Common Stock, the Participant
         has and will rely upon the advice of his/her own legal counsel, tax
         advisors, and/or investment advisors.

     -   The Participant is aware that the Option may be of no practical value,
         that any value it may have depends on its vesting and exercisability as
         well as an increase in the Fair Market Value of the underlying shares
         of Common Stock to an amount in excess of the Exercise Price, and that
         any investment in common shares of a closely held corporation such as
         the Corporation is non-marketable, non-transferable and could require
         capital to be invested for an indefinite period of time, possibly
         without return, and at substantial risk of loss.

     -   The Participant understands that any shares of Common Stock acquired on
         exercise of the Option will be characterized as "restricted securities"
         under the federal securities laws,

                                       3
<PAGE>

         and that, under such laws and applicable regulations, such securities
         may be resold without registration under the Securities Act only in
         certain limited circumstances, including in accordance with the
         conditions of Rule 144 promulgated under the Securities Act, as
         presently in effect, with which the Participant is familiar.

     -   The Participant has read and understands the restrictions and
         limitations set forth in the Plan, this Option Agreement (including
         these Terms), the applicable Exercise Agreement, and the
         Securityholders Agreement, which are imposed on the Option and any
         shares of Common Stock which may be acquired upon exercise of the
         Option.

     -   At no time was an oral representation made to the Participant relating
         to the Option or the purchase of shares of Common Stock and the
         Participant was not presented with or solicited by any promotional
         meeting or material relating to the Option or the Common Stock.

7.       LOCK-UP AGREEMENT.

         Neither the Participant (nor any permitted transferee) may, directly or
indirectly, offer, sell or transfer or dispose of any of the shares of Common
Stock acquired upon exercise of the Option (the "SHARES") or any interest
therein (or agree to do any thereof) (collectively, a "TRANSFER") during the
period commencing as of 14 days prior to and ending one year, or such lesser
period of time as the relevant underwriters may permit, after the effective date
of a registration statement covering any public offering of the Corporation's
securities of which the Participant has notice. (The term "Participant"
includes, where the context so requires, any permitted direct or indirect
transferee of the Participant.) The Participant shall agree and consent to the
entry of stop transfer instructions with the Corporation's transfer agent
against the Transfer of the Corporation's securities beneficially owned by the
Participant and shall conform the limitations hereunder and under the Exercise
Agreement by agreement with and for the benefit of the relevant underwriters by
a lock-up agreement or other agreement in customary form. Notwithstanding
anything else herein to the contrary, this Section 7 shall not be construed so
as to prohibit the Participant from participating in a registration or a public
offering of the Common Stock with respect to any shares which he or she may hold
at that time, provided, however, that such participation shall be at the sole
discretion of the Board.

8.       PLAN.

         The Option and all rights of the Participant under this Option
Agreement are subject to, and the Participant agrees to be bound by, all of the
terms and conditions of the Plan, incorporated herein by this reference. In the
event of a conflict or inconsistency between the terms and conditions of this
Option Agreement and of the Plan, the terms and conditions of the Plan shall
govern. The Participant acknowledges receipt of a copy of the Plan and agrees to
be bound by the terms thereof and of this Option Agreement. The Participant
acknowledges reading and understanding the Plan and this Option Agreement.
Unless otherwise expressly provided in other sections of this Option Agreement,
provisions of the Plan that confer discretionary authority on the Board or the
Committee do not and shall not be deemed to create any rights in the Participant
unless such rights are expressly set forth herein or are otherwise in the sole
discretion of the Board or the Committee so conferred by appropriate action of
the Board or the Committee under the Plan after the date hereof.

9.       ENTIRE AGREEMENT.

         This Option Agreement (including these Terms and together with the
forms of Exercise Agreements and Securityholders Agreement attached hereto) and
the Plan together constitute the

                                       4
<PAGE>

entire agreement and supersede all prior understandings and agreements, written
or oral, of the parties hereto with respect to the subject matter hereof. The
Plan, this Option Agreement and the Exercise Agreements may be amended pursuant
to Section 4.5 of the Plan. Such amendment must be in writing and signed by the
Corporation. The Corporation may, however, unilaterally waive any provision
hereof or of the Exercise Agreements in writing to the extent such waiver does
not adversely affect the interests of the Participant hereunder, but no such
waiver shall operate as or be construed to be a subsequent waiver of the same
provision or a waiver of any other provision hereof.

10.      SATISFACTION OF ALL RIGHTS TO EQUITY.

         The Option is in complete satisfaction of any and all rights that the
Participant may have (under an employment, consulting, or other written or oral
agreement with the Company, or otherwise) to receive (1) stock options or a
restricted stock award with respect to the Company's securities, and/or (2) any
other equity or derivative security in or with respect to the Company. This
Option Agreement supersedes the terms of all prior understandings and
agreements, written or oral, of the parties with respect to such matters. The
Participant shall have no further rights or benefits under any prior agreement
conveying any right with respect to any security or derivative security in or
with respect to the Company. The foregoing notwithstanding, this Section 10
shall not adversely affect the Participant's rights under any prior option or
restricted stock agreement under the Plan (provided such agreement is expressly
labeled as an option, restricted stock, or award agreement under the Plan and is
similar in form to this Option Agreement) which has been signed by an authorized
officer of the Corporation.

11.      GOVERNING LAW; LIMITED RIGHTS; SEVERABILITY.

         11.1. DELAWARE LAW. This Option Agreement and the Exercise Agreements
shall be governed by and construed and enforced in accordance with the laws of
the State of Delaware without regard to conflict of law principles thereunder.

         11.2. LIMITED RIGHTS. The Participant has no rights as a stockholder of
the Corporation with respect to the Option as set forth in Section 4.6 of the
Plan. The Option does not place any limit on the corporate authority of the
Corporation as set forth in Section 4.12 of the Plan.

         11.3. ARBITRATION. Any dispute, controversy or claim arising out of or
relating to this Option Agreement (including these Terms), the Plan, and/or the
applicable Exercise Agreement, their enforcement or interpretation, or because
of an alleged breach, default, or misrepresentation in connection with any of
their provisions, will be determined exclusively by confidential, final and
binding arbitration in Orange County, California, before a sole neutral
arbitrator (the "ARBITRATOR") selected from and in accordance with the rules of
the American Arbitration Association, and such arbitration shall be conducted in
accordance with the provisions of California Civil Procedure Code ss.ss. 1282 -
1284.2 as the exclusive remedy of such dispute. The arbitrator's award in any
such proceeding will be final, binding, and conclusive upon the parties, subject
only to judicial review provided by statute, and a judgment rendered on the
arbitration award can be entered in any state or federal court having
jurisdiction thereof. Disputes, controversies or claims subject to final and
binding arbitration under this Agreement include, without limitation, all those
that could otherwise be tried in court to a judge or jury in the absence of this
Section 11.3. The Participant and the Corporation agree that they each expressly
waive any rights to have such matters heard or tried before a judge or jury in
another tribunal. Nothing in this Section 11.3, however, shall limit the right
of the parties to stipulate and agree to conduct the arbitration before and
pursuant to the then existing rules of any other agreed-upon arbitration
services provider.

                                       5
<PAGE>

         11.4. COMPLIANCE WITH LAWS; SEVERABILITY. This Option Agreement, the
Securityholders Agreement, and the applicable Exercise Agreement are subject to
compliance with all applicable laws (including, without limitation, applicable
securities laws) as set forth in Section 4.3 of the Plan. If the arbitrator
selected in accordance with Section 11.3 or a court of competent jurisdiction
determines that any portion of this Option Agreement, the Plan, the
Securityholders Agreement, or the applicable Exercise Agreement is in violation
of any statute or public policy, then only the portions of this Option
Agreement, the Plan, the Securityholders Agreement, or the Exercise Agreement,
as applicable, which violate such statute or public policy shall be stricken,
and all portions of this Option Agreement, the Plan, the Securityholders
Agreement, and the Exercise Agreement which do not violate any statute or public
policy shall continue in full force and effect. Furthermore, it is the parties'
intent that any court order striking any portion of this Option Agreement, the
Plan, the Securityholders Agreement and/or the Exercise Agreement should modify
the stricken terms as narrowly as possible to give as much effect as possible to
the intentions of the parties hereunder.

         11.5. STOCKHOLDER APPROVAL. Notwithstanding anything else contained
herein to the contrary, the Option and all rights of the Participant under this
Option Agreement are subject to approval of the Plan by the Corporation's
stockholders (such approval to be obtained in accordance with the terms of the
Plan, the Company's Bylaws, and applicable law) within 12 months after the
Effective Date of the Plan.

         -    such purchase shall be at the price of $__________________ per

         -    the Shares are subject to, and following any otherwise permitted
              transfer of the Shares, the Shares shall remain subject to and the
              transferee shall be bound by, the lock-up provisions set forth in
              Section 7 of the Terms, the share legend requirements of Section
              4.3.3 of the Plan, the foregoing provisions of this Section 3, the
              provisions of the Securityholders Agreement, and the arbitration
              provisions of Section 11.3 of the Terms; and

         -    as a condition to any otherwise permitted transfer of the Shares,
              the Corporation may require the transferee to execute a written
              agreement, in a form acceptable to the Committee, that the
              transferee acknowledges and agrees to the foregoing terms and
              restrictions imposed on the Shares.

         4.       PLAN AND OPTION AGREEMENT. The Purchaser acknowledges that all
of his/her rights are subject to, and the Purchaser agrees to be bound by, all
of the terms and conditions of the Plan, the Securityholders Agreement, and the
Option Agreement (including the Terms), each of which is incorporated herein by

of this Exercise Agreement and of the Plan or the Option Agreement shall arise,
the terms and conditions of the Plan and/or the Option Agreement shall govern.
The Purchaser acknowledges receipt of a copy of all documents referenced herein
(including the Terms, the Securityholders Agreement, and a disclosure statement)
and acknowledges reading and understanding these documents and having an
opportunity to ask any questions that he/she may have had about them. Any
controversy or claim arising out of or relating to this Exercise Agreement shall
be submitted to arbitration in accordance with Section 11.3 of the Terms, and
Delaware law shall apply as provided in Section 11.1 of the Terms.

         5.       ENTIRE AGREEMENT. This Exercise Agreement, the Option
Agreement (including the Terms), the Securityholders Agreement, and the Plan
together constitute the entire agreement and supersede all prior understandings
and agreements, written or oral, of the parties hereto with respect to the
subject matter hereof. The Plan, the Option Agreement and this Exercise
Agreement may be amended pursuant to Section 4.5 of the Plan. Such amendment
must be in writing and signed by the Corporation. The Corporation may, however,
unilaterally waive any provision hereof or of the Option Agreement in writing to
the extent such waiver does not adversely affect the interests of the Purchaser
hereunder, but no such waiver shall operate as or be construed to be a
subsequent waiver of the same provision or a waiver of any other provision
hereof.

         6.       NOTICE OF SALE. Upon any sale or other transfer of the Shares
within either one year of the date that they are acquired by the Purchaser or

                        ACCENT OPTICAL TECHNOLOGIES, INC.
                              STOCK INCENTIVE PLAN
                            OPTION EXERCISE AGREEMENT
                          (UNVESTED PORTION OF OPTION)

         The undersigned (the "PURCHASER") hereby irrevocably elects to exercise
his/her right, evidenced by that certain Incentive Stock Option Agreement dated
as of ____________________ (the "OPTION AGREEMENT") under the Accent Optical
Technologies, Inc. Stock Incentive Plan (the "PLAN"), as follows:

         -    the Purchaser hereby irrevocably elects to purchase
              __________________ shares of Common Stock, par value $0.00001 per
              share (the "SHARES"), of Accent Optical Technologies, Inc., a
              Delaware corporation (the "CORPORATION"), and

         -    such purchase shall be at the price of $__________________ per
              share, for an aggregate amount of $__________________ (subject to
              applicable withholding taxes pursuant to Section 4.4 of the Plan).

         Capitalized terms are defined in the Plan or the Option Agreement if
not defined herein.

         1.       INVESTMENT REPRESENTATIONS. The Purchaser acknowledges that
the sale of the Shares by the Purchaser is restricted by SEC Rule 701. The
Purchaser hereby affirms as made as of the date hereof the representations in
Section 6 of the "Terms and Conditions of Incentive Stock Option" (which are
attached to and a part of the Option Agreement, the "TERMS") and such
representations are incorporated herein by this reference. The Purchaser
represents that he/she has no need for liquidity in this investment, has the
ability to bear the economic risk of this investment, and can afford a complete
loss of the purchase price for the Shares.

         The Purchaser acknowledges receipt of the Corporation's condensed
consolidated financial information.

         The Purchaser also understands and acknowledges (a) that the
certificates representing the Shares will be legended as provided for below and
in Section 4.3.3 of the Plan, and (b) that the Corporation has no obligation to
register the Shares or file any registration statement under federal or state
securities laws.

         In addition to the share legend(s) provided for in Section 4.3.3 of the
Plan, the certificates representing the Shares will bear the following legend:

         "THE SHARES ARE SUBJECT TO THE CORPORATION'S RIGHT TO REPURCHASE THEM
         UNDER THE CORPORATION'S STOCK INCENTIVE PLAN AND AN AGREEMENT WITH THE
         CORPORATION THEREUNDER, COPIES OF WHICH ARE AVAILABLE FOR REVIEW AT THE
         OFFICE OF THE SECRETARY OF THE CORPORATION."

         2.       VESTING. The Shares are being acquired prior to the time that
they have become vested in accordance with the terms of the Option Agreement.
Accordingly, the Shares are subject to the Corporation's repurchase right set
forth in Section 5 below and other restrictions set forth herein. The Shares
shall vest, and the Corporation's repurchase right under Section 5 shall lapse,
as of the date(s) that the Option would have otherwise become vested as to such

                                       1
<PAGE>

Shares. The maximum number of Shares that may vest on any occasion or event
shall not exceed the number of shares that would have otherwise vested on such
date under the Option Agreement had the underlying stock option not been
exercised early to acquire the Shares. No additional Shares shall vest after the
Purchaser's Severance Date.

         3.       DELIVERY OF SHARE CERTIFICATE. The Corporation shall issue a
certificate or certificates for the Shares, registered in the name of the
Purchaser, which certificate(s) shall upon redelivery thereof to the Corporation
pursuant to the following provisions of this Section 3 be held by the
Corporation until the restrictions on such Shares shall have lapsed and the
Shares shall thereby have become vested or the Shares represented thereby are
repurchased by the Corporation in accordance with Section 5.

         Upon delivery to the Purchaser of the certificate(s) representing the
Shares, the Purchaser shall redeliver such certificate(s) to the Corporation,
together with a stock power or stock powers, in blank and in substantially the
form attached hereto, with respect to such certificate(s), to be held by the
Corporation pursuant to the terms hereof. The Purchaser hereby appoints the
Corporation and each of its authorized representatives as the Purchaser's
attorney(s)-in-fact to effect any transfer of the Shares that are repurchased by
the Corporation in accordance with the terms hereof or related cash, property or
rights (including Restricted Property, as such term is defined below) to the
Corporation as may be required pursuant to this Exercise Agreement and to
execute such documents as the Corporation or such representatives deem necessary
or advisable in connection with any such transfer.

         Promptly after the vesting of the Shares in accordance with Section 2
above, a certificate or certificates evidencing the number of shares of Common
Stock as to which the restrictions have lapsed or been released or such lesser
number as may be permitted pursuant to Section 4.4 of the Plan (tax withholding)
shall be delivered to the Purchaser or other person entitled under the terms
hereof and of the Plan to receive the shares. The Purchaser or such other person
shall deliver to the Corporation any representations or other documents or
assurances required pursuant to Section 4.3 of the Plan. The Shares so delivered
shall no longer be subject to the Corporation's repurchase right under Section
5, but such shares shall continue to be subject to the other restrictions set
forth herein, in the Option Agreement, and in the Plan. Vested Shares and any
other amounts deliverable pursuant to the Shares shall be delivered and paid
only to the Purchaser or the Purchaser's Beneficiary or Personal Representative,
as the case may be.

         4.       DIVIDEND; VOTING RIGHTS. After the date of issuance of the
Shares, the Purchaser shall be entitled to cash dividends and voting rights with
respect to the Shares, but such rights shall terminate as to any Shares that are
repurchased by the Corporation in accordance with Section 5. Any securities or
other property receivable in respect of the Shares by the Purchaser as a result
of any dividend or other distribution, conversion or exchange of or with respect
to the Shares are, together, referred to as "RESTRICTED PROPERTY." Upon a
repurchase of any Shares by the Corporation in accordance with Section 5, the
Restricted Property related to such repurchased Shares shall be automatically
transferred to the Corporation, without any further action by the Purchaser (or
the Purchaser's Beneficiary or Personal Representative, as the case may be) or
additional consideration from the Corporation. The Corporation may take any
other action necessary or advisable to evidence such transfer. The Purchaser, or
the Purchaser's Beneficiary or Personal Representative, as the case may be,
shall deliver any additional documents of transfer that the Corporation may
request to confirm the transfer of such Restricted Property to the Corporation.

         5.       CORPORATION'S REPURCHASE RIGHT. Subject to the terms and
conditions of this Section 5, the Corporation shall have the right (the
"REPURCHASE RIGHT") (but not the obligation)

                                       2
<PAGE>

to repurchase in one or more transactions in connection with the termination of
the Purchaser's employment by or services to the Company, and the Purchaser (or
any permitted transferee) shall be obligated to sell any of the Shares that have
not, as of the Purchaser's Severance Date, become vested.

         To exercise the Repurchase Right, the Corporation must give written
notice thereof to the Purchaser (the "REPURCHASE NOTICE"). The Repurchase Notice
is irrevocable by the Corporation and must (a) be in writing and signed by an
authorized officer of the Corporation, (b) set forth the Corporation's intent to
exercise the Repurchase Right and contain the total number of Shares to be sold
to the Corporation pursuant to the exercise of the Repurchase Right, (c) be
mailed or delivered to the Purchaser at the Purchaser's address reflected or
last reflected on the Corporation's payroll records or delivered to the
Purchaser in person, and (d) be so mailed or delivered no later than the
ninetieth (90th) day following the Purchaser's Severance Date. If mailed, the
Repurchase Notice shall be enclosed in a properly sealed envelope, addressed as
aforesaid, and deposited (postage prepaid) in a post office or branch post
office regularly maintained by the United States Government. The Repurchase
Notice shall be deemed to have been duly given as of the date mailed or
delivered in accordance with the foregoing provisions.

         The price per Share to be paid by the Corporation upon settlement of
the Corporation's Repurchase Right (the "REPURCHASE PRICE") shall equal the
lesser of (a) the price paid by the Purchaser to exercise the stock option and
acquire such Share, or (b) the Fair Market Value of a Share determined as of the
date of the Call Notice. No interest shall be paid with respect to and no other
adjustments (other than adjustments in accordance with Section 4.2.1 of the Plan
to reflect stock splits and similar changes in capitalization) shall be made to
the Repurchase Price. The closing of any repurchase under this Section 5 shall
be at a date to be specified by the Corporation, such date to be no later than
90 days after the Purchaser's Severance Date. The Repurchase Price shall be paid
at the closing in the form of a check or by cancellation of money purchase
indebtedness.

         Upon a repurchase of any Shares by the Corporation, such repurchased
Shares shall be automatically transferred to the Corporation, without any
further action by the Purchaser (or the Purchaser's Beneficiary or Personal
Representative, as the case may be). The Corporation may exercise its powers
under this Exercise Agreement (including, without limitation, its powers under
Section 3) and take any other action necessary or advisable to evidence such
transfer. The Purchaser, or the Purchaser's Beneficiary or Personal
Representative, as the case may be, shall deliver any additional documents of
transfer that the Corporation may request to confirm the transfer of such
repurchased Shares to the Corporation.

         If the Purchaser (or any permitted transferee who is an employee of the
Company) ceases to be an employee of the Company and holds Shares as to which
the Corporation's Repurchase Right has been exercised, the Purchaser shall be
entitled to the value of such Shares in accordance with the foregoing provisions
of this Section 5, but (unless otherwise required by law) shall no longer be
entitled to participation in the Corporation or other rights as a shareholder
with respect to the Shares subject to the repurchase. To the maximum extent
permitted by law, the Purchaser's rights following the exercise of the
Repurchase Right shall, with respect to the repurchase and the Shares covered
thereby, be solely the rights that he or she has as a general creditor of the
Corporation to receive payment of the amount specified above in this Section 5.

         The Repurchase Right is in addition to, and not in lieu of, any right
that the Corporation may have under the Securityholders Agreement.

<PAGE>

         6.       LIMITATION ON DISPOSITION AND OTHER RESTRICTIONS. The Shares
are subject to and the Purchaser hereby agrees to the following terms and
conditions of the sale of the Shares to the Purchaser:

         -    any transfer of the Shares must comply with all applicable laws as
              set forth in Section 4.3 of the Plan;

         -    in addition to the restrictions on transfer under Sections 1.5 and
              4.3 of the Plan, the Shares may not be sold, assigned,
              transferred, pledged or otherwise disposed of, alienated or
              encumbered, either voluntarily or involuntarily, other than to the
              Corporation or another stockholder of the Corporation, or as may
              expressly be permitted in writing by the Corporation or by will or
              the laws of descent and distribution, at any time prior to the
              later of: (a) the time that they become vested in accordance with
              Section 2, or (b) the earlier of the Public Offering Date or 24
              months after the date of issue;

         -    any Restricted Property in respect of the Shares may not be sold,
              assigned, transferred, pledged or otherwise disposed of, alienated
              or encumbered, either voluntarily or involuntarily, other than by
              will or the laws of descent and distribution, until the time that
              the Shares to which the Restricted Property relates become vested
              in accordance with Section 2.

         -    the Shares are subject to, and following any otherwise permitted
              transfer of the Shares, the Shares shall remain subject to and the
              transferee shall be bound by, the lock-up provisions set forth in
              Section 7 of the Terms, the share legend requirements of Section
              4.3.3 of the Plan and Section 2 above, the Corporation's
              repurchase right set forth in Section 5, the foregoing provisions
              of this Section 6, the Securityholders Agreement, and the
              arbitration provisions of Section 11.3 of the Terms; and

         -    as a condition to any otherwise permitted transfer of the Shares,
              the Corporation may require the transferee to execute a written
              agreement, in a form acceptable to the Committee, that the
              transferee acknowledges and agrees to the foregoing terms and
              restrictions imposed on the Shares.

         7.       PLAN AND OPTION AGREEMENT. The Purchaser acknowledges that all
of his/her rights are subject to, and the Purchaser agrees to be bound by, all
of the terms and conditions of the Plan, the Securityholders Agreement, and the
Option Agreement (including the Terms), each of which is incorporated herein by
this reference. If a conflict or inconsistency between the terms and conditions
of this Exercise Agreement and of the Plan or the Option Agreement shall arise,
the terms and conditions of the Plan and/or the Option Agreement shall govern.
The Purchaser acknowledges receipt of a copy of all documents referenced herein
(including the Terms and a disclosure statement) and acknowledges reading and
understanding these documents and having an opportunity to ask any questions
that he/she may have had about them. Any controversy or claim arising out of or
relating to this Exercise Agreement shall be submitted to arbitration in
accordance with Section 11.3 of the Terms, and Delaware law shall apply as
provided in Section 11.1 of the Terms.

         8.       ENTIRE AGREEMENT. This Exercise Agreement, the Option
Agreement (including the Terms), the Securityholders Agreement, and the Plan
together constitute the entire agreement and supersede all prior understandings
and agreements, written or oral, of the parties hereto with respect to the
subject matter hereof. The Plan, the Option Agreement and this Exercise
Agreement may be amended pursuant to Section 4.5 of the Plan. Such amendment
must be in

                                       4

writing and signed by the Corporation. The Corporation may, however,
unilaterally waive any provision hereof or of the Option Agreement in writing to
the extent such waiver does not adversely affect the interests of the Purchaser
hereunder, but no such waiver shall operate as or be construed to be a
subsequent waiver of the same provision or a waiver of any other provision
hereof.

         9. NOTICE OF SALE. Upon any sale or other transfer of the Shares within
either one year of the date that they are acquired by the Purchaser or two years
after the Award Date set forth in the Option Agreement, the Purchaser agrees to

month commencing with the month following the month in which the Initial Vesting
Date occurs and for the 41 months thereafter.]

(incorporated herein by this reference) and to the Plan. The Option has been
granted to the Participant in addition to, and not in lieu of, any other form of

                TERMS AND CONDITIONS OF NONQUALIFIED STOCK OPTION

1.       VESTING; LIMITS ON EXERCISE.

         As set forth on the cover page of this Option Agreement, the Option
shall vest in percentage installments of the aggregate number of shares of
Common Stock subject to the Option.

         -    Cumulative Exercisability. The Participant has the right to
              exercise the Option (to the extent not previously exercised), and
              such right shall continue, until the expiration or earlier
              termination of the Option.

         -    No Fractional Shares. Fractional share interests shall be
              disregarded, but may be cumulated.

         -    Minimum Exercise. No fewer than 1001 shares of Common Stock may be
              purchased at any one time, unless the number purchased is the
              total number at the time exercisable under the Option.

2.       CONTINUANCE OF EMPLOYMENT/SERVICE REQUIRED; NO EMPLOYMENT/SERVICE
         COMMITMENT.

         The vesting schedule requires continued employment or service through
each applicable vesting date as a condition to the vesting of the applicable
installment of the Option and the rights and benefits under this Option
Agreement. Partial employment or service, even if substantial, during any
vesting period will not entitle the Participant to any proportionate vesting or
avoid or mitigate a termination of rights and benefits upon or following a
termination of employment or services as provided in Section 4 below, under the
Plan, or under the applicable Exercise Agreement (as such term is defined
below).

         Nothing contained in this Option Agreement, the Plan, or any Exercise
Agreement constitutes an employment or service commitment by the Company,
affects the Participant's status, if he or she is an employee, as an employee at
will who is subject to termination without cause, confers upon the Participant
any right to remain employed by or in service to the Company or any Subsidiary,
interferes in any way with the right of the Company or any Subsidiary at any
time to terminate such employment or service, or affects the right of the
Company or any Subsidiary to increase or decrease the Participant's other
compensation.

3.       METHOD OF EXERCISE OF OPTION.

         To the extent that the Participant desires to exercise a portion of the
Option that is then vested, the Participant shall deliver to the Corporation an
executed Exercise Agreement in substantially the form attached hereto as Exhibit
A and satisfy the other exercise procedures described below. The Participant
also has the right, until the date that is ninety (90) days after the Award Date
(the "UNVESTED EXERCISE DEADLINE"), to exercise the unvested portion of the
Option. After the Unvested Exercise Deadline, the Option may only be exercised
to the extent that it is then vested. To the extent that the Participant desires
to exercise a portion of the Option that is not vested, the Participant shall
deliver to the Corporation, on or before the Unvested Exercise Deadline, an
executed Exercise Agreement in substantially the form attached hereto as Exhibit
B and satisfy the other exercise procedures described below. The applicable form
of Exercise Agreement is referred to as the "EXERCISE AGREEMENT."

                                       1
<PAGE>

         The Option is exercisable (whether the exercise is with respect to the
vested or the unvested portion of the Option, as described above) by the
delivery to the Secretary of the Corporation of a written notice stating the
number of shares of Common Stock to be purchased pursuant to the Option and
accompanied by:

         -    delivery of an executed Exercise Agreement in substantially the
              form attached hereto as Exhibit A or Exhibit B, as applicable (see
              the Exercise Agreement discussion above), or such other form as
              the Committee may require from time to time;

         -    delivery of an executed Securityholders Agreement in substantially
              the form attached hereto as Exhibit C or such other form as the
              Committee may require from time to time (the "SECURITYHOLDERS
              AGREEMENT");

         -    payment in full for the Exercise Price of the shares to be
              purchased, in cash or by electronic funds transfer to the
              Corporation, or by certified or cashier's check payable to the
              order of the Corporation subject to such specific procedures or
              directions as the Committee may establish;

         -    satisfaction of the tax withholding provisions of Section 4.4 of
              the Plan; and

         -    any written statements or agreements required pursuant to Section
              4.3 of the Plan.

The Committee also may, but is not required to, authorize a non-cash payment
alternative specified below at or prior to the time of exercise. In which case,
the Exercise Price and/or applicable withholding taxes, to the extent so
authorized, may be paid in full or in part by delivery to the Corporation of:

         -    shares of Common Stock already owned by the Participant, valued at
              their Fair Market Value on the exercise date, provided, however,
              that any shares acquired directly from the Corporation (upon
              exercise of a stock option or otherwise) must have been owned by
              the Participant for at least six (6) months before they can be
              used in connection with an exercise of the Option; and/or

         -    a note meeting the requirements of Section 1.6 of the Plan (or, in
              the case of tax loans, Section 4.4.2 of the Plan).

4.       EARLY TERMINATION OF OPTION.

         The Option, to the extent not previously exercised, and all other
rights in respect thereof, whether vested and exercisable or not, shall
terminate and become null and void prior to the Expiration Date in the event of:

         -    the termination of the Participant's employment or services as
              provided in Section 2.6 of the Plan, or

         -    the termination of the Option pursuant to Section 4.2 of the Plan.

5.       NON-TRANSFERABILITY AND OTHER RESTRICTIONS.

         The Option and any other rights of the Participant under this Option
Agreement or the Plan are nontransferable and exercisable only by the
Participant, except as set forth in Section 1.5 of the Plan. Any shares of
Common Stock issued on exercise of the Option are subject to

                                       2
<PAGE>

substantial restrictions on transfer, and are subject to rights in favor of the
Corporation as set forth herein, in the Securityholders Agreement, and in the
applicable Exercise Agreement.

6.       SECURITIES LAW COMPLIANCE.

         The Participant acknowledges that the Option and the shares of Common
Stock are not being registered under the Securities Act, based, in part, in
reliance upon an exemption from registration under Securities and Exchange
Commission Rule 701 promulgated under the Securities Act of 1933, and a
comparable exemption from qualification under the California Corporate
Securities Law, as each may be amended from time to time. The Participant, by
executing this Option Agreement, hereby makes the following representations to
the Corporation and acknowledges that the Corporation's reliance on federal and
state securities law exemptions from registration and qualification is
predicated, in substantial part, upon the accuracy of these representations:

     -   The Participant is acquiring the Option and, if and when he/she
         exercises the Option, will acquire the shares of Common Stock solely
         for the Participant's own account, for investment purposes only, and
         not with a view to or an intent to sell, or to offer for resale in
         connection with any unregistered distribution, all or any portion of
         the shares within the meaning of the Securities Act, the California
         Corporate Securities Law, or other applicable state securities laws.

     -   The Participant has had an opportunity to ask questions and receive
         answers from the Corporation regarding the terms and conditions of the
         Option and the restrictions imposed on any shares of Common Stock
         purchased upon exercise of the Option. The Participant has been
         furnished with, and/or has access to, such information as he or she
         considers necessary or appropriate for deciding whether to exercise the
         Option and purchase shares of Common Stock. However, in evaluating the
         merits and risks of an investment in the Common Stock, the Participant
         has and will rely upon the advice of his/her own legal counsel, tax
         advisors, and/or investment advisors.

     -   The Participant is aware that the Option may be of no practical value,
         that any value it may have depends on its vesting and exercisability as
         well as an increase in the Fair Market Value of the underlying shares
         of Common Stock to an amount in excess of the Exercise Price, and that
         any investment in common shares of a closely held corporation such as
         the Corporation is non-marketable, non-transferable and could require
         capital to be invested for an indefinite period of time, possibly
         without return, and at substantial risk of loss.

     -   The Participant understands that any shares of Common Stock acquired on
         exercise of the Option will be characterized as "restricted securities"
         under the federal securities laws,
         and that, under such laws and applicable regulations, such securities
         may be resold without registration under the Securities Act only in
         certain limited circumstances, including in accordance with the
         conditions of Rule 144 promulgated under the Securities Act, as
         presently in effect, with which the Participant is familiar.

     -   The Participant has read and understands the restrictions and
         limitations set forth in the Plan, this Option Agreement (including
         these Terms), the applicable Exercise Agreement, and the
         Securityholders Agreement, which are imposed on the Option and any
         shares of Common Stock which may be acquired upon exercise of the
         Option.

                                       3
<PAGE>

     -   At no time was an oral representation made to the Participant relating
         to the Option or the purchase of shares of Common Stock and the
         Participant was not presented with or solicited by any promotional
         meeting or material relating to the Option or the Common Stock.

7.       LOCK-UP AGREEMENT.

         Neither the Participant (nor any permitted transferee) may, directly or
indirectly, offer, sell or transfer or dispose of any of the shares of Common
Stock acquired upon exercise of the Option (the "SHARES") or any interest
therein (or agree to do any thereof) (collectively, a "TRANSFER") during the
period commencing as of 14 days prior to and ending one year, or such lesser
period of time as the relevant underwriters may permit, after the effective date
of a registration statement covering any public offering of the Corporation's
securities of which the Participant has notice. (The term "Participant"
includes, where the context so requires, any permitted direct or indirect
transferee of the Participant.) The Participant shall agree and consent to the
entry of stop transfer instructions with the Corporation's transfer agent
against the Transfer of the Corporation's securities beneficially owned by the
Participant and shall conform the limitations hereunder and under the Exercise
Agreement by agreement with and for the benefit of the relevant underwriters by
a lock-up agreement or other agreement in customary form. Notwithstanding
anything else herein to the contrary, this Section 7 shall not be construed so
as to prohibit the Participant from participating in a registration or a public
offering of the Common Stock with respect to any shares which he or she may hold
at that time, provided, however, that such participation shall be at the sole
discretion of the Board.

8.       PLAN.

         The Option and all rights of the Participant under this Option
Agreement are subject to, and the Participant agrees to be bound by, all of the
terms and conditions of the Plan, incorporated herein by this reference. In the
event of a conflict or inconsistency between the terms and conditions of this
Option Agreement and of the Plan, the terms and conditions of the Plan shall
govern. The Participant acknowledges receipt of a copy of the Plan and agrees to
be bound by the terms thereof and of this Option Agreement. The Participant
acknowledges reading and understanding the Plan and this Option Agreement.
Unless otherwise expressly provided in other sections of this Option Agreement,
provisions of the Plan that confer discretionary authority on the Board or the
Committee do not and shall not be deemed to create any rights in the Participant
unless such rights are expressly set forth herein or are otherwise in the sole
discretion of the Board or the Committee so conferred by appropriate action of
the Board or the Committee under the Plan after the date hereof.

9.       ENTIRE AGREEMENT.

         This Option Agreement (including these Terms and together with the
forms of Exercise Agreements and Securityholders Agreement attached hereto) and
the Plan together constitute the entire agreement and supersede all prior
understandings and agreements, written or oral, of the parties hereto with
respect to the subject matter hereof. The Plan, this Option Agreement and the
Exercise Agreements may be amended pursuant to Section 4.5 of the Plan. Such
amendment must be in writing and signed by the Corporation. The Corporation may,
however, unilaterally waive any provision hereof or of the Exercise Agreements
in writing to the extent such waiver does not adversely affect the interests of
the Participant hereunder, but no such waiver shall operate as or be construed
to be a subsequent waiver of the same provision or a waiver of any other
provision hereof.

                                       4
<PAGE>

10.      SATISFACTION OF ALL RIGHTS TO EQUITY.

         The Option is in complete satisfaction of any and all rights that the
Participant may have (under an employment, consulting, or other written or oral
agreement with the Company, or otherwise) to receive (1) stock options or a
restricted stock award with respect to the Company's securities, and/or (2) any
other equity or derivative security in or with respect to the Company. This
Option Agreement supersedes the terms of all prior understandings and
agreements, written or oral, of the parties with respect to such matters. The
Participant shall have no further rights or benefits under any prior agreement
conveying any right with respect to any security or derivative security in or
with respect to the Company. The foregoing notwithstanding, this Section 10
shall not adversely affect the Participant's rights under any prior option or
restricted stock agreement under the Plan (provided such agreement is expressly
labeled as an option, restricted stock, or award agreement under the Plan and is
similar in form to this Option Agreement) which has been signed by an authorized
officer of the Corporation.

11.      GOVERNING LAW; LIMITED RIGHTS; SEVERABILITY.

         11.1. DELAWARE LAW. This Option Agreement and the Exercise Agreements
shall be governed by and construed and enforced in accordance with the laws of
the State of Delaware without regard to conflict of law principles thereunder.

         11.2. LIMITED RIGHTS. The Participant has no rights as a stockholder of
the Corporation with respect to the Option as set forth in Section 4.6 of the
Plan. The Option does not place any limit on the corporate authority of the
Corporation as set forth in Section 4.12 of the Plan.

         11.3. ARBITRATION. Any dispute, controversy or claim arising out of or
relating to this Option Agreement (including these Terms), the Plan, and/or the
applicable Exercise Agreement, their enforcement or interpretation, or because
of an alleged breach, default, or misrepresentation in connection with any of
their provisions, will be determined exclusively by confidential, final and
binding arbitration in Orange County, California, before a sole neutral
arbitrator (the "ARBITRATOR") selected from and in accordance with the rules of
the American Arbitration Association, and such arbitration shall be conducted in
accordance with the provisions of California Civil Procedure Code ss.ss. 1282 -
1284.2 as the exclusive remedy of such dispute. The arbitrator's award in any
such proceeding will be final, binding, and conclusive upon the parties, subject
only to judicial review provided by statute, and a judgment rendered on the
arbitration award can be entered in any state or federal court having
jurisdiction thereof. Disputes, controversies or claims subject to final and
binding arbitration under this Agreement include, without limitation, all those
that could otherwise be tried in court to a judge or jury in the absence of this
Section 11.3. The Participant and the Corporation agree that they each expressly
waive any rights to have such matters heard or tried before a judge or jury in
another tribunal. Nothing in this Section 11.3, however, shall limit the right
of the parties to stipulate and agree to conduct the arbitration before and
pursuant to the then existing rules of any other agreed-upon arbitration
services provider.

         11.4. COMPLIANCE WITH LAWS; SEVERABILITY. This Option Agreement, the
Securityholders Agreement, and the applicable Exercise Agreement are subject to
compliance with all applicable laws (including, without limitation, applicable
securities laws) as set forth in Section 4.3 of the Plan. If the arbitrator
selected in accordance with Section 11.3 or a court of competent jurisdiction
determines that any portion of this Option Agreement, the Plan, the
Securityholders Agreement, or the applicable Exercise Agreement is in violation
of any statute or public policy, then only the portions of this Option
Agreement, the Plan, the Securityholders Agreement, or the Exercise Agreement,
as applicable, which violate such statute or public policy shall be stricken,
and all portions of this Option Agreement, the Plan, the Securityholders
Agreement, and the Exercise Agreement which do not violate any statute or public
policy

                                       5
<PAGE>

shall continue in full force and effect. Furthermore, it is the parties' intent
that any court order striking any portion of this Option Agreement, the Plan,
the Securityholders Agreement and/or the Exercise Agreement should modify the
stricken terms as narrowly as possible to give as much effect as possible to the
intentions of the parties hereunder.

         11.5. STOCKHOLDER APPROVAL. Notwithstanding anything else contained
herein to the contrary, the Option and all rights of the Participant under this
Option Agreement are subject to approval of the Plan by the Corporation's
stockholders (such approval to be obtained in accordance with the terms of the
Plan, the Company's Bylaws, and applicable law) within 12 months after the
Effective Date of the Plan.

              share, for an aggregate amount of $__________________ (subject to
              applicable withholding taxes pursuant to Section 4.4 of the Plan).

         Capitalized terms are defined in the Plan or the Option Agreement if
not defined herein.

         1.       DELIVERY OF SHARE CERTIFICATE. The Purchaser requests that a

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

-------------------.

         2.       INVESTMENT REPRESENTATIONS. The Purchaser acknowledges that
the sale of the Shares by the Purchaser is restricted by SEC Rule 701. The
Purchaser hereby affirms as made as of the date hereof the representations in
Section 6 of the "Terms and Conditions of Nonqualified Stock Option" (which are
attached to and a part of the Option Agreement, the "TERMS") and such
representations are incorporated herein by this reference. The Purchaser
represents that he/she has no need for liquidity in this investment, has the

         The Purchaser acknowledges receipt of the Corporation's condensed
consolidated financial information.

         The Purchaser also understands and acknowledges (a) that the

the Shares or file any registration statement under federal or state securities
laws.

         3.       LIMITATION ON DISPOSITION AND OTHER RESTRICTIONS. The Shares

              transferee shall be bound by, the lock-up provisions set forth in
              Section 7 of the Terms, the share legend requirements of Section
              4.3.3 of the Plan, the foregoing provisions of this Section 3, the
              provisions of the Securityholders Agreement, and the arbitration
              provisions of Section 11.3 of the Terms; and

         -    as a condition to any otherwise permitted transfer of the Shares,
              the Corporation may require the transferee to execute a written
              agreement, in a form acceptable to the Committee, that the
              transferee acknowledges and agrees to the foregoing terms and
              restrictions imposed on the Shares.

         4.       PLAN AND OPTION AGREEMENT. The Purchaser acknowledges that all
of his/her rights are subject to, and the Purchaser agrees to be bound by, all
of the terms and conditions of the Plan, the Securityholders Agreement, and the
Option Agreement (including the Terms), each of which is incorporated herein by
this reference. If a conflict or inconsistency between the terms and conditions

Agreement may be amended pursuant to Section 4.5 of the Plan. Such amendment
must be in writing and signed by the Corporation. The Corporation may, however,
unilaterally waive any provision hereof or of the Option Agreement in writing to

                        ACCENT OPTICAL TECHNOLOGIES, INC.
                              STOCK INCENTIVE PLAN
                            OPTION EXERCISE AGREEMENT
                          (UNVESTED PORTION OF OPTION)

         The undersigned (the "PURCHASER") hereby irrevocably elects to exercise
his/her right, evidenced by that certain Nonqualified Stock Option Agreement
dated as of ____________________ (the "OPTION AGREEMENT") under the Accent
Optical Technologies, Inc. Stock Incentive Plan (the "PLAN"), as follows:

         -    the Purchaser hereby irrevocably elects to purchase
              __________________ shares of Common Stock, par value $0.00001 per
              share (the "SHARES"), of Accent Optical Technologies, Inc., a
              Delaware corporation (the "CORPORATION"), and

         -    such purchase shall be at the price of $__________________ per
              share, for an aggregate amount of $__________________ (subject to
              applicable withholding taxes pursuant to Section 4.4 of the Plan).

         Capitalized terms are defined in the Plan or the Option Agreement if
not defined herein.

         1.       INVESTMENT REPRESENTATIONS. The Purchaser acknowledges that
the sale of the Shares by the Purchaser is restricted by SEC Rule 701. The
Purchaser hereby affirms as made as of the date hereof the representations in
Section 6 of the "Terms and Conditions of Nonqualified Stock Option" (which are
attached to and a part of the Option Agreement, the "TERMS") and such
representations are incorporated herein by this reference. The Purchaser
represents that he/she has no need for liquidity in this investment, has the
ability to bear the economic risk of this investment, and can afford a complete
loss of the purchase price for the Shares.

         The Purchaser acknowledges receipt of the Corporation's condensed
consolidated financial information.

         The Purchaser also understands and acknowledges (a) that the
certificates representing the Shares will be legended as provided for below and
in Section 4.3.3 of the Plan, and (b) that the Corporation has no obligation to
register the Shares or file any registration statement under federal or state
securities laws.

         In addition to the share legend(s) provided for in Section 4.3.3 of the
Plan, the certificates representing the Shares will bear the following legend:

         "THE SHARES ARE SUBJECT TO THE CORPORATION'S RIGHT TO REPURCHASE THEM
         UNDER THE CORPORATION'S STOCK INCENTIVE PLAN AND AN AGREEMENT WITH THE
         CORPORATION THEREUNDER, COPIES OF WHICH ARE AVAILABLE FOR REVIEW AT THE
         OFFICE OF THE SECRETARY OF THE CORPORATION."

         2.       VESTING. The Shares are being acquired prior to the time that
they have become vested in accordance with the terms of the Option Agreement.
Accordingly, the Shares are subject to the Corporation's repurchase right set
forth in Section 5 below and other restrictions set forth herein. The Shares
shall vest, and the Corporation's repurchase right under Section 5 shall lapse,
as of the date(s) that the Option would have otherwise become vested as to such

                                       1
<PAGE>

Shares. The maximum number of Shares that may vest on any occasion or event
shall not exceed the number of shares that would have otherwise vested on such
date under the Option Agreement had the underlying stock option not been
exercised early to acquire the Shares. No additional Shares shall vest after the
Purchaser's Severance Date.

         3.       DELIVERY OF SHARE CERTIFICATE. The Corporation shall issue a
certificate or certificates for the Shares, registered in the name of the
Purchaser, which certificate(s) shall upon redelivery thereof to the Corporation
pursuant to the following provisions of this Section 3 be held by the
Corporation until the restrictions on such Shares shall have lapsed and the
Shares shall thereby have become vested or the Shares represented thereby are
repurchased by the Corporation in accordance with Section 5.

         Upon delivery to the Purchaser of the certificate(s) representing the
Shares, the Purchaser shall redeliver such certificate(s) to the Corporation,
together with a stock power or stock powers, in blank and in substantially the
form attached hereto, with respect to such certificate(s), to be held by the
Corporation pursuant to the terms hereof. The Purchaser hereby appoints the
Corporation and each of its authorized representatives as the Purchaser's
attorney(s)-in-fact to effect any transfer of the Shares that are repurchased by
the Corporation in accordance with the terms hereof or related cash, property or
rights (including Restricted Property, as such term is defined below) to the
Corporation as may be required pursuant to this Exercise Agreement and to
execute such documents as the Corporation or such representatives deem necessary
or advisable in connection with any such transfer.

         Promptly after the vesting of the Shares in accordance with Section 2
above, a certificate or certificates evidencing the number of shares of Common
Stock as to which the restrictions have lapsed or been released or such lesser
number as may be permitted pursuant to Section 4.4 of the Plan (tax withholding)
shall be delivered to the Purchaser or other person entitled under the terms
hereof and of the Plan to receive the shares. The Purchaser or such other person
shall deliver to the Corporation any representations or other documents or
assurances required pursuant to Section 4.3 of the Plan. The Shares so delivered
shall no longer be subject to the Corporation's repurchase right under Section
5, but such shares shall continue to be subject to the other restrictions set
forth herein, in the Option Agreement, and in the Plan. Vested Shares and any
other amounts deliverable pursuant to the Shares shall be delivered and paid
only to the Purchaser or the Purchaser's Beneficiary or Personal Representative,
as the case may be.

         4.       DIVIDEND; VOTING RIGHTS. After the date of issuance of the
Shares, the Purchaser shall be entitled to cash dividends and voting rights with
respect to the Shares, but such rights shall terminate as to any Shares that are
repurchased by the Corporation in accordance with Section 5. Any securities or
other property receivable in respect of the Shares by the Purchaser as a result
of any dividend or other distribution, conversion or exchange of or with respect
to the Shares are, together, referred to as "RESTRICTED PROPERTY." Upon a
repurchase of any Shares by the Corporation in accordance with Section 5, the
Restricted Property related to such repurchased Shares shall be automatically
transferred to the Corporation, without any further action by the Purchaser (or
the Purchaser's Beneficiary or Personal Representative, as the case may be) or
additional consideration from the Corporation. The Corporation may take any
other action necessary or advisable to evidence such transfer. The Purchaser, or
the Purchaser's Beneficiary or Personal Representative, as the case may be,
shall deliver any additional documents of transfer that the Corporation may
request to confirm the transfer of such Restricted Property to the Corporation.

         5.       CORPORATION'S REPURCHASE RIGHT. Subject to the terms and
conditions of this Section 5, the Corporation shall have the right (the
"REPURCHASE RIGHT") (but not the obligation)

                                       2
<PAGE>

to repurchase in one or more transactions in connection with the termination of
the Purchaser's employment by or services to the Company, and the Purchaser (or
any permitted transferee) shall be obligated to sell any of the Shares that have
not, as of the Purchaser's Severance Date, become vested.

         To exercise the Repurchase Right, the Corporation must give written
notice thereof to the Purchaser (the "REPURCHASE NOTICE"). The Repurchase Notice
is irrevocable by the Corporation and must (a) be in writing and signed by an
authorized officer of the Corporation, (b) set forth the Corporation's intent to
exercise the Repurchase Right and contain the total number of Shares to be sold
to the Corporation pursuant to the exercise of the Repurchase Right, (c) be
mailed or delivered to the Purchaser at the Purchaser's address reflected or
last reflected on the Corporation's payroll records or delivered to the
Purchaser in person, and (d) be so mailed or delivered no later than the
ninetieth (90th) day following the Purchaser's Severance Date. If mailed, the
Repurchase Notice shall be enclosed in a properly sealed envelope, addressed as
aforesaid, and deposited (postage prepaid) in a post office or branch post
office regularly maintained by the United States Government. The Repurchase
Notice shall be deemed to have been duly given as of the date mailed or
delivered in accordance with the foregoing provisions.

         The price per Share to be paid by the Corporation upon settlement of
the Corporation's Repurchase Right (the "REPURCHASE PRICE") shall equal the
lesser of (a) the price paid by the Purchaser to exercise the stock option and
acquire such Share, or (b) the Fair Market Value of a Share determined as of the
date of the Call Notice. No interest shall be paid with respect to and no other
adjustments (other than adjustments in accordance with Section 4.2.1 of the Plan
to reflect stock splits and similar changes in capitalization) shall be made to
the Repurchase Price. The closing of any repurchase under this Section 5 shall
be at a date to be specified by the Corporation, such date to be no later than
90 days after the Purchaser's Severance Date. The Repurchase Price shall be paid
at the closing in the form of a check or by cancellation of money purchase
indebtedness.

         Upon a repurchase of any Shares by the Corporation, such repurchased
Shares shall be automatically transferred to the Corporation, without any
further action by the Purchaser (or the Purchaser's Beneficiary or Personal
Representative, as the case may be). The Corporation may exercise its powers
under this Exercise Agreement (including, without limitation, its powers under
Section 3) and take any other action necessary or advisable to evidence such
transfer. The Purchaser, or the Purchaser's Beneficiary or Personal
Representative, as the case may be, shall deliver any additional documents of
transfer that the Corporation may request to confirm the transfer of such
repurchased Shares to the Corporation.

         If the Purchaser (or any permitted transferee who is an employee of the
Company) ceases to be an employee of the Company and holds Shares as to which
the Corporation's Repurchase Right has been exercised, the Purchaser shall be
entitled to the value of such Shares in accordance with the foregoing provisions
of this Section 5, but (unless otherwise required by law) shall no longer be
entitled to participation in the Corporation or other rights as a shareholder
with respect to the Shares subject to the repurchase. To the maximum extent
permitted by law, the Purchaser's rights following the exercise of the
Repurchase Right shall, with respect to the repurchase and the Shares covered
thereby, be solely the rights that he or she has as a general creditor of the
Corporation to receive payment of the amount specified above in this Section 5.

         The Repurchase Right is in addition to, and not in lieu of, any right
that the Corporation may have under the Securityholders Agreement.

         6.       LIMITATION ON DISPOSITION AND OTHER RESTRICTIONS. The Shares
are subject to and the Purchaser hereby agrees to the following terms and
conditions of the sale of the Shares to the Purchaser:

         -    any transfer of the Shares must comply with all applicable laws as
              set forth in Section 4.3 of the Plan;

         -    in addition to the restrictions on transfer under Sections 1.5 and
              4.3 of the Plan, the Shares may not be sold, assigned,
              transferred, pledged or otherwise disposed of, alienated or
              encumbered, either voluntarily or involuntarily, other than to the
              Corporation or another stockholder of the Corporation, or as may
              expressly be permitted in writing by the Corporation or by will or
              the laws of descent and distribution, at any time prior to the
              later of: (a) the time that they become vested in accordance with
              Section 2, or (b) the earlier of the Public Offering Date or 24
              months after the date of issue;

         -    any Restricted Property in respect of the Shares may not be sold,
              assigned, transferred, pledged or otherwise disposed of, alienated
              or encumbered, either voluntarily or involuntarily, other than by
              will or the laws of descent and distribution, until the time that
              the Shares to which the Restricted Property relates become vested
              in accordance with Section 2.

         -    the Shares are subject to, and following any otherwise permitted
              transfer of the Shares, the Shares shall remain subject to and the
              transferee shall be bound by, the lock-up provisions set forth in
              Section 7 of the Terms, the share legend requirements of Section
              4.3.3 of the Plan and Section 2 above, the Corporation's
              repurchase right set forth in Section 5, the foregoing provisions
              of this Section 6, the Securityholders Agreement, and the
              arbitration provisions of Section 11.3 of the Terms; and

         -    as a condition to any otherwise permitted transfer of the Shares,
              the Corporation may require the transferee to execute a written
              agreement, in a form acceptable to the Committee, that the
              transferee acknowledges and agrees to the foregoing terms and
              restrictions imposed on the Shares.

         7.       PLAN AND OPTION AGREEMENT. The Purchaser acknowledges that all
of his/her rights are subject to, and the Purchaser agrees to be bound by, all
of the terms and conditions of the Plan, the Securityholders Agreement, and the
Option Agreement (including the Terms), each of which is incorporated herein by

understanding these documents and having an opportunity to ask any questions
that he/she may have had about them. Any controversy or claim arising out of or
relating to this Exercise Agreement shall be submitted to arbitration in
accordance with Section 11.3 of the Terms, and Delaware law shall apply as

together constitute the entire agreement and supersede all prior understandings
and agreements, written or oral, of the parties hereto with respect to the
subject matter hereof. The Plan, the Option Agreement and this Exercise
Agreement may be amended pursuant to Section 4.5 of the Plan. Such amendment
must be in

                                       4

writing and signed by the Corporation. The Corporation may, however,
unilaterally waive any provision hereof or of the Option Agreement in writing to
the extent such waiver does not adversely affect the interests of the Purchaser
hereunder, but no such waiver shall operate as or be construed to be a
subsequent waiver of the same provision or a waiver of any other provision
hereof.

         THE COMPANY HAS MADE AND MAKES NO REPRESENTATION REGARDING THE
ADVISABILITY OF, OR REGARDING THE TAX, FINANCIAL AND OTHER CONSEQUENCES OF, AN
ELECTION TO PURCHASE THE SHARES PRIOR TO THE TIME(S) THAT THEY HAVE BECOME
