                                    QDA, INC.

                      2003 STOCK OPTION/STOCK ISSUANCE PLAN

                                   ARTICLE ONE

                               GENERAL PROVISIONS

I.       PURPOSE OF THE PLAN

         This 2003 Stock Option/Stock Issuance Plan is intended to promote the
interests of QDA, Inc., a California corporation, by providing eligible persons
in the Corporation's employ or service with the opportunity to acquire a
proprietary interest, or otherwise increase their proprietary interest, in the
Corporation as an incentive for them to continue in such employ or service.

         Capitalized terms herein shall have the meanings assigned to such terms
in the attached Appendix.

II.      STRUCTURE OF THE PLAN

         A.       The Plan shall be divided into two (2) separate equity
programs:

                  (i)      the Option Grant Program under which eligible persons
         may, at the discretion of the Plan Administrator, be granted options to
         purchase shares of Common Stock, and

                  (ii)     the Stock Issuance Program under which eligible
         persons may, at the discretion of the Plan Administrator, be issued
         shares of Common Stock directly, either through the immediate purchase
         of such shares or as a bonus for services rendered the Corporation (or
         any Parent or Subsidiary).

         B.       The provisions of Articles One and Four shall apply to both
equity programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

III.     ADMINISTRATION OF THE PLAN

         A.       The Plan shall be administered by the Board. However, any or
all administrative functions otherwise exercisable by the Board may be delegated
to the Committee. Members of the Committee shall serve for such period of time
as the Board may determine and shall be subject to removal by the Board at any
time. The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

<PAGE>

         B.       The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of, the Plan and any
outstanding options or stock issuances thereunder as it may deem necessary or
advisable. Decisions of the Plan Administrator shall be final and binding on all
parties who have an interest in the Plan or any option grant or stock issuance
thereunder.

IV.      ELIGIBILITY

         A.       The persons eligible to participate in the Plan are as
follows:

                  (i)      Employees,

                  (ii)     non-employee members of the Board or the non-employee
         members of the board of directors of any Parent or Subsidiary, and

                  (iii)    consultants and other independent advisors who
         provide services to the Corporation (or any Parent or Subsidiary).

         B.       The Plan Administrator shall have full authority to determine,
(i) with respect to the grants made under the Option Grant Program, which
eligible persons are to receive such grants, the time or times when those grants
are to be made, the number of shares to be covered by each such grant, the
status of the granted option as either an Incentive Option or a Non-Statutory
Option, the time or times when each option is to become exercisable, the vesting
schedule (if any) applicable to the option shares and the maximum term for which
the option is to remain outstanding, and (ii) with respect to stock issuances
made under the Stock Issuance Program, which eligible persons are to receive
such issuances, the time or times when those issuances are to be made, the
number of shares to be issued to each Participant, the vesting schedule (if any)
applicable to the issued shares and the consideration to be paid by the
Participant for such shares.

         C.       The Plan Administrator shall have the absolute discretion
either to grant options in accordance with the Option Grant Program or to effect
stock issuances in accordance with the Stock Issuance Program.

V.       STOCK SUBJECT TO THE PLAN

         A.       The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. The maximum number of shares
of Common Stock which may be issued over the term of the Plan shall not exceed
one million five hundred thousand (1,500,000) shares.

         B.       Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant provisions of Article
Two. Unvested shares issued under the Plan and subsequently repurchased by the
Corporation, at a price per share not greater than the option exercise or direct
issue price paid per share, pursuant to the Corporation's repurchase rights
under the Plan shall be

                                       2
<PAGE>

added back to the number of shares of Common Stock reserved for issuance under
the Plan and shall accordingly be available for reissuance through one or more
subsequent option grants or direct stock issuances under the Plan.

         C.       Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and/or class of securities issuable
under the Plan and (ii) the number and/or class of securities and the exercise
price per share in effect under each outstanding option in order to prevent the
dilution or enlargement of benefits thereunder. The adjustments determined by
the Plan Administrator shall be final, binding and conclusive. In no event shall
any such adjustments be made in connection with the conversion of one or more
outstanding shares of the Corporation's preferred stock into shares of Common
Stock.

                              OPTION GRANT PROGRAM

I.       OPTION TERMS

         Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

         A.       EXERCISE PRICE.

                  1.       The exercise price per share shall be fixed by the
Plan Administrator in accordance with the following provisions:

                           (i)      The exercise price per share shall not be
         less than eighty-five percent (85%) of the Fair Market Value per share
         of Common Stock on the option grant date.

                           (ii)     If the person to whom the option is granted
         is a 10% Stockholder, then the exercise price per share shall not be
         less than one hundred ten percent (110%) of the Fair Market Value per
         share of Common Stock on the option grant date.

                  2.       The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Four and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12 of the 1934 Act at the time the option is exercised, then the
exercise price may also be paid as follows:

                           (i)      in shares of Common Stock held for the
         requisite period necessary to avoid a charge to the Corporation's
         earnings for financial reporting purposes and valued at Fair Market
         Value on the Exercise Date, or

                           (ii)     to the extent the option is exercised for
         vested shares, through a special sale and remittance procedure pursuant
         to which the Optionee shall concurrently provide irrevocable
         instructions (A) to a Corporation-designated brokerage firm to effect
         the immediate sale of the purchased shares and remit to the
         Corporation, out of the sale proceeds available on the settlement date,
         sufficient funds to cover the aggregate exercise price payable for the
         purchased shares plus all applicable income and employment taxes
         required to be withheld by the Corporation by reason of such exercise
         and (B) to the Corporation to deliver the certificates for the
         purchased shares directly to such brokerage firm in order to complete
         the sale.

                                       4
<PAGE>

         Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

         B.       EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option grant. However, no option shall have a term in excess
often (10) years measured from the option grant date.

         C.       EFFECT OF TERMINATION OF SERVICE.

                  1.       The following provisions shall govern the exercise of
any options held by the Optionee at the time of cessation of Service or death:

                           (i)      Should the Optionee cease to remain in
         Service for any reason other than death, Disability or Misconduct, then
         the Optionee shall have a period of three (3) months following the date
         of such cessation of Service during which to exercise each outstanding
         option held by such Optionee.

                           (ii)     Should Optionee's Service terminate by
         reason of Disability, then the Optionee shall have a period of twelve
         (12) months following the date of such cessation of Service during
         which to exercise each outstanding option held by such Optionee.

                           (iii)    If the Optionee dies while holding an
         outstanding option, then the personal representative of his or her
         estate or the person or persons to whom the option is transferred
         pursuant to the Optionee's will or the laws of inheritance or the
         Optionee's designated beneficiary or beneficiaries of that option shall
         have a twelve (12)-month period following the date of the Optionee's
         death to exercise such option.

                           (iv)     Under no circumstances, however, shall any
         such option be exercisable after the specified expiration of the option
         term.

                           (v)      During the applicable post-Service exercise
         period, the option may not be exercised in the aggregate for more than
         the number of vested shares for which the option is exercisable on the
         date of the Optionee' s cessation of Service. Upon the expiration of
         the applicable exercise period or (if earlier) upon the expiration of
         the option term, the option shall terminate and cease to be outstanding
         for any vested shares for which the option has not been exercised.
         However, the option shall, immediately upon the Optionee's cessation of
         Service, terminate and cease to be outstanding with respect to any and
         all option shares for which the option is not otherwise at the time
         exercisable or in which the Optionee is not otherwise at that time
         vested.

                           (vi)     Should Optionee's Service be terminated for
         Misconduct or should Optionee otherwise engage in Misconduct while
         holding one or more outstanding options under the Plan, then all those
         options shall terminate immediately and cease to remain outstanding.

                                       5
<PAGE>

                  2.       The Plan Administrator shall have the discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

                           (i)      extend the period of time for which the
         option is to remain exercisable following Optionee's cessation of
         Service or death from the limited period otherwise in effect for that
         option to such greater period of time as the Plan Administrator shall
         deem appropriate, but in no event beyond the expiration of the option
         term, and/or

                           (ii)     permit the option to be exercised, during
         the applicable post-Service exercise period, not only with respect to
         the number of vested shares of Common Stock for which such option is
         exercisable at the time of the Optionee's cessation of Service but also
         with respect to one or more additional installments in which the
         Optionee would have vested under the option had the Optionee continued
         in Service.

         D.       STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become the
recordholder of the purchased shares.

         E.       UNVESTED SHARES. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase any or all of those unvested
shares at a price per share equal to the lower of (i) the exercise price paid
per share or (ii) the Fair Market Value per share of Common Stock at the time of
Optionee's cessation of Service. The terms upon which such repurchase right
shall be exercisable (including the period and procedure for exercise and the
appropriate vesting schedule for the purchased shares) shall be established by
the Plan Administrator and set forth in the document evidencing such repurchase
right. The Plan Administrator may not impose a vesting schedule upon any option
grant or the shares of Common Stock subject to that option which is more
restrictive than twenty percent (20%) per year vesting, with the initial vesting
to occur not later than one (1) year after the option grant date. However, such
limitation shall not be applicable to any option grants made to individuals who
are officers of the Corporation, non-employee Board members or independent
consultants.

         F.       FIRST REFUSAL RIGHTS. Until such time as the Common Stock is
first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan. Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

         G.       LIMITED TRANSFERABILITY OF OPTIONS. An Incentive Stock Option
shall be exercisable only by the Optionee during his or her lifetime and shall
not be assignable or transferable other than by will or by the laws of
inheritance following the Optionee's death. A Non-Statutory Option may be
assigned in whole or in part during the Optionee's lifetime to one or more
members of the Optionee's family or to a trust established exclusively for one
or more

                                       6
<PAGE>

such family members or to Optionee's former spouse, to the extent such
assignment is in connection with the Optionee's estate plan or pursuant to a
domestic relations order. The assigned portion may only be exercised by the
person or persons who acquire a proprietary interest in the Non-Statutory Option
pursuant to the assignment. The terms applicable to the assigned portion shall
be the same as those in effect for the option immediately prior to such
assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate. Notwithstanding the foregoing, the
Optionee may also designate one or more persons as the beneficiary or
beneficiaries of his or her outstanding options under the Plan, and those
options shall, in accordance with such designation, automatically be transferred
to such beneficiary or beneficiaries upon the Optionee' s death while holding
those options. Such beneficiary or beneficiaries shall take the transferred
options subject to all the terms and conditions of the applicable agreement
evidencing each such transferred option, including (without limitation) the
limited time period during which the option may be exercised following the
Optionee's death.

II.      INCENTIVE OPTIONS

         The terms specified below shall be applicable to all Incentive Options.
Except as modified by the provisions of this Section II, all the provisions of
Articles One, Two and Four shall be applicable to Incentive Options. Options
which are specifically designated as Non-Statutory Options shall not be subject
to the terms of this Section II.

         A.       ELIGIBILITY. Incentive Options may only be granted to
Employees.

         B.       EXERCISE PRICE. The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

         C.       DOLLAR LIMITATION. The aggregate Fair Market Value of the
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one (1) calendar
year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

         D.       10% STOCKHOLDER. If any Employee to whom an Incentive Option
is granted is a 10% Stockholder, then the option term shall not exceed five (5)
years measured from the option grant date.

III.     CHANGE IN CONTROL

         A.       The shares subject to each option outstanding under the Plan
at the time of a Change in Control shall automatically vest in full so that each
such option shall, immediately prior to the effective date of the Change in
Control, become exercisable for all of the shares of Common Stock at the time
subject to that option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock. However, the shares subject to an
outstanding option shall NOT vest on such an accelerated basis if and to the
extent: (i) such option is assumed

                                       7
<PAGE>

by the successor corporation (or parent thereof) or otherwise continued in full
force and effect pursuant to the terms of the Change in Control transaction and
any repurchase rights of the Corporation with respect to the unvested option
shares are concurrently assigned to such successor corporation (or parent
thereof) or otherwise continued in effect or (ii) such option is to be replaced
with a cash incentive program of the Corporation or any successor corporation
which preserves the spread existing on the unvested option shares at the time of
the Change in Control and provides for subsequent payout of that spread in
accordance with the same vesting schedule applicable to those unvested option
shares or (iii) the acceleration of such option is subject to other limitations
imposed by the Plan Administrator at the time of the option grant.

         B.       All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Change in Control, except to
the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) or otherwise continued in full force and effect
pursuant to the terms of the Change in Control transaction or (ii) such
accelerated vesting is precluded by other limitations imposed by the Plan
Administrator at the time the repurchase right is issued.

         C.       Immediately following the consummation of the Change in
Control, all outstanding options shall terminate and cease to be outstanding,
except to the extent assumed by the successor corporation (or parent thereof) or
otherwise continued in effect pursuant to the terms of the Change in Control
transaction.

         D.       Each option which is assumed in connection with a Change in
Control or otherwise continued in effect shall be appropriately adjusted,
immediately after such Change in Control, to apply to the number and class of
securities which would have been issuable to the Optionee in consummation of
such Change in Control, had the option been exercised immediately prior to such
Change in Control. Appropriate adjustments shall also be made to (i) the number
and class of securities available for issuance under the Plan following the
consummation of such Change in Control and (ii) the exercise price payable per
share under each outstanding option, provided the aggregate exercise price
payable for such securities shall remain the same. To the extent the actual
holders of the Corporation's outstanding Common Stock receive cash consideration
for their Common Stock in consummation of the Change in Control, the successor
corporation may, in connection with the assumption of the outstanding options
under this Plan, substitute one or more shares of its own common stock with a
fair market value equivalent to the cash consideration paid per share of Common
Stock in such Change in Control.

         E.       The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to structure one or more options so that those options shall
automatically accelerate and vest in full (and any repurchase rights of the
Corporation with respect to the unvested shares subject to those options shall
immediately terminate) upon the occurrence of a Change in Control, whether or
not those options are to be assumed in the Change in Control or otherwise
continued in effect.

         F.       The Plan Administrator shall also have full power and
authority, exercisable either at the time the option is granted or at any time
while the option remains outstanding, to structure such option so that the
shares subject to that option will automatically vest on an

                                       8
<PAGE>

accelerated basis should the Optionee's Service terminate by reason of an
Involuntary Termination within a designated period (not to exceed eighteen (18)
months) following the effective date of any Change in Control in which the
option is assumed or otherwise continued in effect and the repurchase rights
applicable to those shares do not otherwise terminate. Any option so accelerated
shall remain exercisable for the fully-vested option shares until the expiration
or sooner termination of the option term. In addition, the Plan Administrator
may provide that one or more of the Corporation's outstanding repurchase rights
with respect to shares held by the Optionee at the time of such Involuntary
Termination shall immediately terminate on an accelerated basis, and the shares
subject to those terminated rights shall accordingly vest at that time.

         G.       The portion of any Incentive Option accelerated in connection
with a Change in Control shall remain exercisable as an Incentive Option only to
the extent the applicable One Hundred Thousand Dollar ($100,000) limitation is
not exceeded. To the extent such dollar limitation is exceeded, the accelerated
portion of such option shall be exercisable as a Non-Statutory Option under the
Federal tax laws.

         H.       The grant of options under the Plan shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

IV.      CANCELLATION AND REGRANT OF OPTIONS

         The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                             STOCK ISSUANCE PROGRAM

I.       STOCK ISSUANCE TERMS

         Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

         A.       PURCHASE PRICE.

                  1.       The purchase price per share shall be fixed by the
Plan Administrator but shall not be less than eighty-five percent (85%) of the
Fair Market Value per share of Common Stock on the issue date. However, the
purchase price per share of Common Stock issued to a 10% Stockholder shall not
be less than one hundred percent (100%) of such Fair Market Value.

                  2.       Subject to the provisions of Section I of Article
Four, shares of Common Stock may be issued under the Stock Issuance Program for
any of the following items of consideration which the Plan Administrator may
deem appropriate in each individual instance:

                           (i)      cash or check made payable to the
         Corporation, or

                           (ii)     past services rendered to the Corporation
         (or any Parent or Subsidiary).

         B.       VESTING PROVISIONS.

                  1.       Shares of Common Stock issued under the Stock
Issuance Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. However, the Plan Administrator may not impose a vesting schedule
upon any stock issuance effected under the Stock Issuance Program which is more
restrictive than twenty percent (20%) per year vesting, with initial vesting to
occur not later than one (1) year after the issuance date. Such limitation shall
not apply to any Common Stock issuances made to the officers of the Corporation,
non-employee Board members or independent consultants.

                  2.       Any new, substituted or additional securities or
other property (including money paid other than as a regular cash dividend)
which the Participant may have the right to receive with respect to the
Participant's unvested shares of Common Stock by reason of any stock dividend,
stock split, recapitalization, combination of shares, exchange of shares or
other change affecting the outstanding Common Stock as a class without the
Corporation's receipt of consideration shall be issued subject to (i) the same
vesting requirements applicable to the Participant's unvested shares of Common
Stock and (ii) such escrow arrangements as the Plan Administrator shall deem
appropriate.

                                       10
<PAGE>

                  3.       The Participant shall have full stockholder rights
with respect to any shares of Common Stock issued to the Participant under the
Stock Issuance Program, whether or not the Participant's interest in those
shares is vested. Accordingly, the Participant shall have the right to vote such
shares and to receive any regular cash dividends paid on such shares.

                  4.       Should the Participant cease to remain in Service
while holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares. To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the lower of (i) the cash consideration paid for the surrendered
shares or (ii) the Fair Market Value of those shares at the time of
Participant's cessation of Service and shall cancel the unpaid principal balance
of any outstanding purchase-money note of the Participant attributable to such
surrendered shares by the applicable clause (i) or (ii) amount.

                  5.       The Plan Administrator may in its discretion waive
the surrender and cancellation of one or more unvested shares of Common Stock
(or other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to those shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

         C.       FIRST REFUSAL RIGHTS. Until such time as the Common Stock is
first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Participant (or any successor in interest) of any shares of Common Stock issued
under the Stock Issuance Program. Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

II.      CHANGE IN CONTROL

         A.       Upon the occurrence of a Change in Control, all outstanding
repurchase rights under the Stock Issuance Program shall terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, except to the extent: (i) those repurchase
rights are assigned to the successor corporation (or parent thereof) or
otherwise continued in full force and effect pursuant to the terms of the Change
in Control transaction or (ii) such accelerated vesting is precluded by other
limitations imposed by the Plan Administrator at the time the repurchase right
is issued.

         B.       The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase rights with respect to those shares remain
outstanding, to provide that those rights shall automatically terminate on an
accelerated basis, and the shares of Common Stock subject to those terminated

                                       11
<PAGE>

rights shall immediately vest, in the event the Participant's Service should
subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control in which those repurchase rights are assigned to
the successor corporation (or parent thereof) or otherwise continued in full
force and effect.

III.     SHARE ESCROW/LEGENDS

         Unvested shares may, in the Plan Administrator's discretion, be held in
escrow by the Corporation until the Participant's interest in such shares vests
or may be issued directly to the Participant with restrictive legends on the
certificates evidencing those unvested shares.

                                  MISCELLANEOUS

I.       FINANCING

         The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Option Grant Program or the purchase price
for shares issued under the Stock Issuance Program by delivering a full-recourse
promissory note payable in one or more installments which bears interest at a
market rate and is secured by the purchased shares. In no event, however, may
the maximum credit available to the Optionee or Participant exceed the sum of
(i) the aggregate option exercise price or purchase price payable for the
purchased shares (less the par value of those shares) plus (ii) any applicable
income and employment tax liability incurred by the Optionee or the Participant
in connection with the option exercise or share purchase.

II.      EFFECTIVE DATE AND TERM OF PLAN

         A.       The Plan shall become effective when adopted by the Board, but
no option granted under the Plan may be exercised, and no shares shall be issued
under the Plan, until the Plan is approved by the Corporation's stockholders. If
such stockholder approval is not obtained within twelve (12) months after the
date of the Board's adoption of the Plan, then all options previously granted
under the Plan shall terminate and cease to be outstanding, and no further
options shall be granted and no shares shall be issued under the Plan. Subject
to such limitation, the Plan Administrator may grant options and issue shares
under the Plan at any time after the effective date of the Plan and before the
date fixed herein for termination of the Plan.

         B.       The Plan shall terminate upon the earliest of (i) the
expiration of the ten (10)-year period measured from the date the Plan is
adopted by the Board, (ii) the date on which all shares available for issuance
under the Plan shall have been issued as vested shares or (iii) the termination
of all outstanding options in connection with a Change in Control. All options
and unvested stock issuances outstanding at the time of a clause (i) termination
event shall continue to have full force and effect in accordance with the
provisions of the documents evidencing those options or issuances.

III.     AMENDMENT OF THE PLAN

         A.       The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no such
amendment or modification shall adversely affect the rights and obligations with
respect to options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws and regulations.

         B.       Options may be granted under the Option Grant Program and
shares may be issued under the Stock Issuance Program which are in each instance
in excess of the number of shares actually issued under those programs shall be
held in escrow until there is obtained

                                       13
<PAGE>

stockholder approval of an amendment sufficiently increasing the number of
shares of Common Stock available for issuance under the Plan. If such
stockholder approval is not obtained within twelve (12) months after the date
the first such excess grants or issuances are made, then (i) any unexercised
options granted on the basis of such excess shares shall terminate and cease to
be outstanding and (ii) the Corporation shall promptly refund to the Optionees
and the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable Short Term Federal Rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically cancelled and cease to
be outstanding.

IV.      USE OF PROCEEDS

         Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

V.       WITHHOLDING

         The Corporation's obligation to deliver shares of Common Stock upon the
exercise of any options granted under the Plan or upon the issuance or vesting
of any shares issued under the Plan shall be subject to the satisfaction of all
applicable income and employment tax withholding requirements.

VI.      REGULATORY APPROVALS

         The implementation of the Plan, the granting of any options under the
Plan and the issuance of any shares of Common Stock (i) upon the exercise of any
option or (ii) under the Stock Issuance Program shall be subject to the
Corporation's procurement of all approvals and permits required by regulatory
authorities having jurisdiction over the Plan, the options granted under it and
the shares of Common Stock issued pursuant to it.

VII.     NO EMPLOYMENT OR SERVICE RIGHTS

         Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

VIII.    FINANCIAL REPORTS

         The Corporation shall deliver a balance sheet and an income statement
at least annually to each individual holding an outstanding option under the
Plan, unless such individual is a key Employee whose duties in connection with
the Corporation (or any Parent or Subsidiary) assure such individual access to
equivalent information.

         Corporation's outstanding securities pursuant to a tender or exchange
         offer made directly to the Corporation's stockholders.

         such price is reported by the National Association of Securities
         Dealers on the Nasdaq National Market and published in The Wall Street
         Journal. If there is no closing selling price for the Common Stock on

         price per share of Common Stock on the date in question on the Stock
         Exchange determined by the Plan Administrator to be the primary market
         for the Common Stock, as such price is officially quoted in the
         composite tape of transactions on such exchange and published in The
         Wall Street Journal. If there is no closing selling price for the
         Common Stock on the date in question, then the Fair Market Value shall

         any Stock Exchange nor traded on the Nasdaq National Market, then the
         Fair Market Value shall be determined by the Plan Administrator after
         taking into account such factors as the Plan Administrator shall deem

         the individual's consent.

         M.       MISCONDUCT shall mean the commission of any act of fraud,
embezzlement or dishonesty by the Optionee or Participant, any unauthorized use
or disclosure by such person of confidential information or trade secrets of the
Corporation (or any Parent or Subsidiary), or any other intentional misconduct

amended.

                            AMBIT DESIGN SYSTEMS, INC

                           INCENTIVE STOCK OPTION PLAN

         1.       PURPOSE OF PLAN. This Incentive Stock Option Plan ("Plan") is
intended to encourage ownership of shares of AMBIT DESIGN SYSTEMS, INC., a
California corporation ("Company"), by key employees of the Company and to
provide additional incentive for them to promote the success of the Company's
business. Options granted under this Plan are intended to meet the requirements
of Section 422 of the Internal Revenue Code of 1986, as amended ("the Code").
The Plan shall not confer upon any employee of the Company any right with
respect to continuation of employment with the Company, nor shall it interfere
in any way with the Company's right to terminate such employment at any time,
with or without cause.

         2.       SHARES SUBJECT TO PLAN. There will be reserved for use upon
the exercise of options to be granted from time to time under the Plan
("Options"), an aggregate of 1,000,000 shares of common stock of the Company,
which shares may be in whole or in part, as the Board of Directors of the
Company ("Board of Directors") shall from time to time determine, authorized but
unissued shares of common stock or shares of issued common stock which have been
reacquired by the Company. If an Option expires or terminates for any reason
without having been exercised in full, the unpurchased shares covered thereby
shall (unless the Plan has been terminated) be added to the shares otherwise
available for Options which may be granted in accordance with the terms of the
Plan. Shares purchased pursuant to the Plan and later repurchased by the Company
shall not be available for future grant or sale under the Plan.

         3.       ADMINISTRATION OF PLAN. The Board of Directors shall, subject
to the provisions of the Plan, have plenary authority in its discretion to
determine the employees of the Company to whom Options shall be granted, the
number of shares to be covered by each of the Options, and the time or times at
which Options shall be granted and may be exercisable; to interpret the Plan; to
prescribe, amend, and rescind rules and regulations relating to it; and to make
all other determinations necessary or advisable for the administration of the
Plan; provided, however, that, in the case of employees who are also directors
of the Company, Options shall be granted only upon approval of a majority of
disinterested directors.

         4.       ELIGIBLE EMPLOYEES.

                  a.       Options may be granted from time to time to any
employees of the Company selected by the Board of Directors whether or not the
grantee has previously received one or more Options hereunder. In no event shall
an Option be granted to any person who, immediately before such Option is
granted, owns (as defined in Section 424(d) of the Code) shares possessing more
than ten percent (10%) of the total combined voting power of all classes of
stock of the Company or any subsidiary unless, at the time such Option is
granted, the purchase price of the shares covered by such Option is at least one
hundred ten percent (110%) of the fair market value of such shares and such
Option by its terms is not exercisable after the expiration of five (5) years
from the date such Option is granted.

<PAGE>

                  b.       In making any determination as to employees to whom
Options shall be granted and as to the number of shares to be covered by such
Options, the Board of Directors shall take into account the duties of the
respective employees, their present and potential contributions to the success
of the Company and such other factors as the Board of Directors deems relevant
in connection with accomplishing the purpose of the Plan.

         5.       LIMITATION ON SHARES SUBJECT TO OPTIONS. The aggregate fair
market value (determined as of the time an Option is granted) of all of the
shares with respect to which incentive stock options are exercisable for the
first time by the employee during any calendar year (under this Plan or any
other incentive stock option plan of the Company and any parent or subsidiary
corporation) shall not exceed the sum of One Hundred Thousand Dollars
($100,000). For purposes of the preceding sentence, Options shall be taken into
account in the order in which they were granted and the market value of such
shares shall be determined as of the time the Option with respect to such shares
was granted.

         6.       OPTION PRICES. The purchase price of the shares to be covered
by each Option shall be one hundred percent (100%) (or one hundred ten percent
(110%) if the conditions described in Section 4.a above apply) of the fair
market value of the shares as determined by the Board of Directors in good faith
at the time of granting the Option.

         7.       TERMS OF OPTIONS. Except as provided in 4.a above, each Option
must be exercised within ten (10) years from the date of grant. The Option term
may be subject to termination prior to the expiration of the period specified in
this paragraph as provided hereinafter.

         8.       EXERCISE OF OPTION. The Board of Directors shall determine, at
the time an Option is granted, the time or times at which the rights under such
Option may be exercised. An Option may not be exercised at any time unless the
holder thereof has been in the continuous employ of the Company from the date of
the granting of the Option to the date of either its exercise or the death of
the holder. Options may be exercised only in the manner set forth in the form of
Option Agreement attached hereto and marked as Exhibit A.

         9.       DISSOLUTION, LIQUIDATION, REORGANIZATION. Notwithstanding
Section 8 above, in the event the shareholders of the Company approve a
dissolution or liquidation of the Company, the holder of an Option shall have
the right to exercise his or her Option as to all or any part of the shares
covered by such Option which would not otherwise be exercisable by reason of an
insufficient lapse of time, during a time specified by the Board of Directors or
described in the Option Agreement.

         In the event of a Reorganization (defined below) in which the Company
is not the surviving or acquiring company or in which the Company is or becomes
a wholly-owned subsidiary of another company after the effective date of the
Reorganization, then the Board of Directors shall terminate all Options issued
under this Plan and the procedure described in the preceding paragraph shall
apply; or, if there is a reorganization agreement which specifically provides
for a change, conversion or exchange of Options issued under this Plan for
securities of another corporation, then such provision shall apply and the Board
of Directors shall make appropriate adjustments.

                                       2
<PAGE>

         The term "Reorganization" as used herein shall mean any statutory
merger, statutory consolidation, sale of all or substantially all of the assets
of the Company or sale of securities of the Company pursuant to which the
Company is or becomes a wholly-owned subsidiary of another company after the
effective date of such Reorganization.

         10.      NONTRANSFERABILITY. An Option shall not be transferable other
than by will or the laws of descent and distribution, and an Option may be
exercised during the lifetime of the employee only by the employee.

         11.      TERMINATION OF EMPLOYMENT.

                  a.       TERMINATION OF OPTION RIGHTS. In the event the
employment by the Company of any employee to whom an Option has been granted is
terminated for any reason other than death or disability, the Option may be
exercised within sixty (60) days of termination of employment to the extent the
employee would have been entitled to do so on the date of said termination.

                  b.       DEATH OF AN EMPLOYEE. If an employee to whom an
Option has been granted dies while employed by the Company, such Option may be
exercised to the extent the employee would have been entitled to do so at the
date of his or her death, by the employee's heirs, executors, administrators, or
other personal representative at any time within three (3) months after the
employee's death but not more than five (5) years and three (3) months after the
date on which such Option shall have been granted.

                  c.       DISABILITY OF EMPLOYEE. In the event of termination
of an employee's employment with the Company as a result of his or her total and
permanent disability (as defined in Section 22(e)(3) of the Code), such employee
may, but only within six (6) months from the date of such termination (but in no
event later than the date of expiration of the term of such Option as set forth
in the Option Agreement), exercise his or her Option to the extent such employee
was entitled to exercise it at the date of such termination. To the extent that
such employee was not entitled to exercise the Option at the date of
termination, or if such employee does not exercise such Option within the time
specified herein, the Option shall terminate.

                  d.       REPURCHASE OPTION. In the event the employment by the
Company of an employee who has purchased shares by exercise of an Option is
terminated for any reason, the Company shall have the option to repurchase any
or all of those shares at a price equal to one hundred percent (100%) of the
then fair market value of the shares as determined by the Board of Directors in
good faith.

         12.      COMPANY'S RIGHT OF FIRST REFUSAL. The Company shall have a
right of first refusal in the event an employee desires to sell or otherwise
dispose of any shares acquired by exercise of an Option granted pursuant to this
Plan.

         13.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. In the event of
changes in the outstanding shares of the Company, the Board of Directors shall
adjust the number of shares as to which Options may be granted to any employee.
No adjustment shall be made in the minimum number of shares which may be
purchased at any time.

         14.      EFFECTIVENESS OF PLAN. This Plan shall become effective only
after its adoption by the Board of Directors and the approval of the Plan by an
affirmative vote of a majority-in-interest of all the outstanding shares of the
Company. The Board of Directors adopted this Plan on December 1, 1994. A
majority-in-interest of the outstanding shares of the Company approved the Plan
on January 31, 1995. The effective date of this Plan shall be December 1, 1994.

         15.      TIME OF GRANTING OPTIONS. Neither anything contained in the
Plan or in any resolution adopted or to be adopted by the Board of Directors or
the shareholders of the Company nor any action taken by the Board of Directors
shall constitute the granting of any Option. The granting of an Option shall
take place only when a written option agreement substantially in the form of the
option agreement attached hereto and marked Exhibit A has been duly executed and
delivered by or on behalf of the Company and the employee to whom such Option is
being granted.

         16.      TERMINATION AND AMENDMENT OF PLAN. The Plan shall terminate on
the tenth (10th) anniversary of the earlier of either the adoption by the
Company or approval by the shareholders of the company, and an Option shall not
be granted under the Plan after that date. The Plan, including the attached form
of option agreement, may at any time or from time to time be terminated,
modified, or amended by the shareholders of the Company by the affirmative vote
of a majority in interest of all the shares of the Company. The Board of
Directors may at any time and from time to time modify or amend the Plan,
including such form of option agreement, in such respects as it deems advisable
in order that the Options shall qualify as incentive stock options pursuant to
the provisions of Section 422 of the Code and supporting regulations, if any, or
to conform to any change in the law or in any other respect. The termination or
any modification or amendment of the Plan shall not, without the consent of an
employee, affect the employee's rights under an Option theretofore granted to
him or her.
