                           OCEN COMMUNICATIONS, INC.

                           STOCK ISSUANCE AGREEMENT
                           ------------------------

          AGREEMENT made as of this _____ day of ______________ 199___, by and
oCen Communications, Inc., a California corporation, and _________, Participant
in the Corporation's 1998 Stock Option/Stock Issuance Plan.

          All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

     A.  PURCHASE OF SHARES
         ------------------

          1.  Purchase. Participant hereby purchases ___________ shares of
              --------
Common Stock (the "Purchased Shares") pursuant to the provisions of the Stock
Issuance Program at the purchase price of $ ___________ per share (the "Purchase
Price").

          2.  Payment.  Concurrently with the delivery of this Agreement to the
              -------
Corporation,  Participant shall pay the Purchase Price for the Purchased Shares
in cash or through a full-recourse interest-bearing promissory payable in full
to the Corporation in one year and shall deliver a duly-executed blank
Assignment Separate from Certificate (in the form attached hereto as Exhibit I)
with respect to the Purchased Shares.

          3.  Shareholder Rights. Until such time as the Corporation exercises
              ------------------
the Repurchase Right or the First Refusal Right, Participant (or any successor
in interest) shall have all shareholder rights (including voting, dividend and
liquidation rights) with respect to the Purchased Shares, subject, however, to
the transfer restrictions of Articles B and C.

     B.  SECURITIES LAW COMPLIANCE
         -------------------------

          1.  Restricted Securities. The Purchased Shares have not been
              ---------------------
registered under the 1933 Act and are being issued to Participant in reliance
upon the exemption from such registration provided by SEC Rule 701 for stock
issuances under compensatory benefit plans such as the Plan. Participant hereby
confirms that Participant has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available. Accordingly,
Participant hereby acknowledges that Participant is prepared to hold the
Purchased Shares for an indefinite period and that Participant is aware that SEC
Rule 144 issued under the 1933 Act which exempts certain resales of unrestricted
securities is not presently available to exempt the resale of the Purchased
Shares from the registration requirements of the 1933 Act.

          2.  Disposition of Purchased Shares. Participant shall make no
              -------------------------------
disposition of the Purchased Shares (other than a Permitted Transfer) unless and
until there is compliance with all of the following requirements:
<PAGE>

          (i)   Participant shall have provided the Corporation with a written
     summary of the terms and conditions of the proposed disposition.

          (ii)  Participant shall have complied with all requirements of this
     Agreement applicable to the disposition of the Purchased Shares.

          (iii) Participant shall have provided the Corporation with written
     assurances, in form and substance satisfactory to the Corporation, that (a)
     the proposed disposition does not require registration of the Purchased
     Shares under the 1933 Act or (b) all appropriate action necessary for
     compliance with the registration requirements of the 1933 Act or any
     exemption from registration available under the 1933 Act (including Rule
     144) has been taken.

          The Corporation shall not be required (i) to transfer on its books any
                                ---
Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement or (ii) to treat as the owner of the Purchased
                             --
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

          3.  Restrictive Legends. The stock certificates for the Purchased
              -------------------
Shares shall be endorsed with one or more of the following restrictive legends:

          "The shares represented by this certificate have not been registered
under the Securities Act of 1933.  The shares may not be sold or offered for
sale in the absence of (a) an effective registration statement for the shares
under such Act, (b) a "no action" letter of the Securities and Exchange
Commission with respect to such sale or offer or (c) satisfactory assurances to
the Corporation that registration under such Act is not required with respect to
such sale or offer."

          "The shares represented by this certificate are subject to certain
repurchase rights and rights of first refusal granted to the Corporation and
accordingly may not be sold, assigned, transferred, encumbered, or in any manner
disposed of except in conformity with the terms of a written agreement dated
______________________, 199__ between the Corporation and the registered holder
of the shares (or the predecessor in interest to the shares).  A copy of such
agreement is maintained at the Corporation's principal corporate offices."

     C.  TRANSFER RESTRICTIONS
         ---------------------

          1.  Restriction on Transfer. Except for any Permitted Transfer,
              -----------------------
Participant shall not transfer, assign, encumber or otherwise dispose of any of
the Purchased Shares which are subject to the Repurchase Right. In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right or the Market Stand-Off.

          2.  Transferee Obligations. Each person (other than the Corporation)
              ----------------------
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to

                                       2
<PAGE>

(i) the Repurchase Right, (ii) the First Refusal Right and (iii) the Market
Stand-Off, to the same extent such shares would be so subject if retained by
Participant.

          3.  Market Stand-Off.
              ----------------

               (a)  In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters. Such restriction (the "Market Stand-Off") shall
be in effect for such period of time from and after the effective date of the
final prospectus for the offering as may be requested by the Corporation or such
underwriters. In no event, however, shall such period exceed one hundred eighty
(180) days and the Market Stand-Off shall in all events terminate two (2) years
after the effective date of the Corporation's initial public offering.

               (b)  Owner shall be subject to the Market Stand-Off provided and
                                                                   ------------
only if the officers and directors of the Corporation are also subject to
-------
similar restrictions.

               (c)  Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

               (d)  In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

          D.  REPURCHASE RIGHT
              ----------------

               1.  Grant. The Corporation is hereby granted the right (the
                   -----
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date Participant ceases for any reason to remain in Service, to
repurchase at the Purchase Price any or all of the Purchased Shares in which
Participant is not, at the time of his or her cessation of Service, vested in
accordance with the Vesting Schedule (such shares to be hereinafter referred to
as the "Unvested Shares").

               2.  Exercise of the Repurchase Right. The Repurchase Right shall
                   --------------------------------
be exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period. The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice. The certificates representing the Unvested Shares
to be repurchased shall be delivered to the Corporation on or before the close
of business on the date specified for the repurchase. Concurrently with the
receipt of such stock certificates, the Corporation shall pay to Owner, in cash
or cash equivalents (including the cancellation of any purchase-money
indebtedness), an amount equal to the

                                       3
<PAGE>

Purchase Price previously paid for the Unvested Shares which are to be
repurchased from Owner.

          3.  Termination of the Repurchase Right. The Repurchase Right shall
              -----------------------------------
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2. In addition, the Repurchase Right shall terminate
and cease to be exercisable with respect to any and all Purchased Shares in
which Participant vests in accordance with the following Vesting Schedule:

          Participant shall vest in twenty-five percent (25%) of the Purchased
Shares, and the Repurchase Right shall concurrently lapse with respect to those
Purchased Shares, upon Participant's completion of one (1) year of Service
measured from ________________________, 199____.

               Participant shall vest in the remaining seventy-five percent
     (75%) of the Purchased Shares, and the Repurchase Right shall concurrently
     lapse with respect to those Purchased Shares, in a series of thirty-six
     (36) successive equal monthly installments upon Participant's completion of
     each additional month of Service over the thirty-six (36)-month period
     measured from the vesting date for the first twenty-five percent (25%) of
     the Purchased Shares.

               All Purchased Shares as to which the Repurchase Right lapses
     shall, however, remain subject to (i) the First Refusal Right and (ii) the
     Market Stand-Off.

          4.  Recapitalization. Any new, substituted or additional securities or
              ----------------
other property (including cash paid other than as a regular cash dividend) which
is by reason of any Recapitalization distributed with respect to the Purchased
Shares shall be immediately subject to the Repurchase Right and any escrow
requirements hereunder, but only to the extent the Purchased Shares are at the
time covered by such right or escrow requirements. Appropriate adjustments to
reflect such distribution shall be made to the number and/or class of Purchased
Shares subject to this Agreement and to the price per share to be paid upon the
exercise of the Repurchase Right in order to reflect the effect of any such
Recapitalization upon the Corporation's capital structure; provided, however,
that the aggregate purchase price shall remain the same.

          5.  Corporate Transaction.
              ---------------------

               (a)  The Repurchase Right shall automatically terminate in its
entirety, and all the Purchased Shares shall vest in full, immediately prior to
the consummation of any Corporate Transaction, except to the extent the
Repurchase Right is to be assigned to the successor entity in such Corporate
Transaction.

               (b)  To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to any new securities
or other property (including any cash payments) received in exchange for the
Purchased Shares in consummation of the Corporate Transaction, but only to the
extent the Purchased Shares are at the time covered by such right. Appropriate
adjustments shall be made to the price per share payable upon exercise of the
Repurchase Right to reflect the effect of the Corporate Transaction upon the
Corporation's

                                       4
<PAGE>

capital structure; provided, however, that the aggregate purchase price shall
                   --------
remain the same. The new securities or other property (including any cash
payments) issued or distributed with respect to the Purchased Shares in
consummation of the Corporate Transaction shall be immediately deposited in
escrow with the Corporation (or the successor entity) and shall not be released
from escrow until Participant vests in such securities or other property in
accordance with the same Vesting Schedule in effect for the Purchased Shares.

     E.  RIGHT OF FIRST REFUSAL
         ----------------------

          1.  Grant. The Corporation is hereby granted the right of first
              -----
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Participant has vested in accordance
with the provisions of Article D. For purposes of this Article E, the term
"transfer" shall include any sale, assignment, pledge, encumbrance or other
disposition of the Purchased Shares intended to be made by Owner, but shall not
include any Permitted Transfer.

          2.  Notice of Intended Disposition. In the event any Owner of
              ------------------------------
Purchased Shares in which Participant has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.

          3.  Exercise of the First Refusal Right. The Corporation shall, for a
              -----------------------------------
period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents. Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
twenty-five (25)-day exercise period. If such right is exercised with respect to
all the Target Shares, then the Corporation shall effect the repurchase of such
shares, including payment of the purchase price, not more than five (5) business
days after delivery of the Exercise Notice; and at such time the certificates
representing the Target Shares shall be delivered to the Corporation.

          Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property.  If Owner and the Corporation
cannot agree on such cash value within ten (10) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an appraiser
of recognized standing selected by Owner and the Corporation or, if they cannot
agree on an appraiser within twenty (20) days after the Corporation's receipt of
the Disposition Notice, each shall select an appraiser of recognized standing
and the two (2) appraisers shall designate a third appraiser of recognized
standing, whose appraisal shall be determinative of such value.  The cost of
such appraisal shall be shared equally by Owner and the Corporation.  The
closing shall then be held

                                       5
<PAGE>

on the later of (i) the fifth (5th) business day following delivery of the
       -----
Exercise Notice or (ii) the fifth (5th) business day after such valuation shall
have been made.

          4.  Non-Exercise of the First Refusal Right. In the event the Exercise
              ---------------------------------------
Notice is not given to Owner prior to the expiration of the twenty-five (25)-day
exercise period, Owner shall have a period of thirty (30) days thereafter in
which to sell or otherwise dispose of the Target Shares to the third-party
offeror identified in the Disposition Notice upon terms (including the purchase
price) no more favorable to such third-party offeror than those specified in the
Disposition Notice; provided, however, that any such sale or disposition must
not be effected in contravention of the provisions of Articles B and C. The
third-party offeror shall acquire the Target Shares free and clear of the
Repurchase Right and the First Refusal Right, but the acquired shares shall
remain subject to the provisions of Article B and Paragraph C.3. In the event
Owner does not effect such sale or disposition of the Target Shares within the
specified thirty (30)-day period, the First Refusal Right shall continue to be
applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses.

          5.  Partial Exercise of the First Refusal Right. In the event the
              -------------------------------------------
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within five (5) business days after Owner's receipt of the Exercise
Notice, to effect the sale of the Target Shares pursuant to either of the
following alternatives:

               (i)  sale or other disposition of all the Target Shares to the
     third-party offeror identified in the Disposition Notice, but in full
     compliance with the requirements of Paragraph E.4, as if the Corporation
     did not exercise the First Refusal Right; or

               (ii) sale to the Corporation of the portion of the Target Shares
     which the Corporation has elected to purchase, such sale to be effected in
     substantial conformity with the provisions of Paragraph E.3. The First
     Refusal Right shall continue to be applicable to any subsequent disposition
     of the remaining Target Shares until such right lapses.

          Failure of Owner to deliver timely notification to the Corporation
shall be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.

          6.  Recapitalization/Reorganization.
              -------------------------------

               (a)  Any new, substituted or additional securities or other
     property which is by reason of any Recapitalization distributed with
     respect to the Purchased Shares shall be immediately subject to the First
     Refusal Right, but only to the extent the Purchased Shares are at the time
     covered by such right.

               (b)  In the event of a Reorganization, the First Refusal Right
     shall remain in full force and effect and shall apply to the new capital
     stock or other property received in exchange for the Purchased Shares in
     consummation of the Reorganization, but only to the extent the Purchased
     Shares are at the time covered by such right.

                                       6
<PAGE>

          7.  Lapse. The First Refusal Right shall lapse upon the earliest to
              -----
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination is made by
the Board that a public market exists for the outstanding shares of Common Stock
or (iii) a firm commitment underwritten public offering, pursuant to an
effective registration statement under the 1933 Act, covering the offer and sale
of the Common Stock in the aggregate amount of at least ten million dollars
($10,000,000). However, the Market Stand-Off shall continue to remain in full
force and effect following the lapse of the First Refusal Right.

     F.  SPECIAL TAX ELECTION
         --------------------

          1.  Section 83(b) Election. Under Code Section 83, the excess of the
              ----------------------
Fair Market Value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date. For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Participant may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions. Such election must be filed
with the Internal Revenue Service within thirty (30) days after the date of this
Agreement. Even if the Fair Market Value of the Purchased Shares on the date of
this Agreement equals the Purchase Price paid (and thus no tax is payable), the
election must be made to avoid adverse tax consequences in the future. THE FORM
FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO. PARTICIPANT
UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-
DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE FORFEITURE
RESTRICTIONS LAPSE.

          2.  FILING RESPONSIBILITY. PARTICIPANT ACKNOWLEDGES THAT IT IS
PARTICIPANT'S SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY
ELECTION UNDER CODE SECTION 83(b), EVEN IF PARTICIPANT REQUESTS THE CORPORATION
OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF.

     G.  GENERAL PROVISIONS
         ------------------

          1.  Assignment. The Corporation may assign the Repurchase Right and/or
              ----------
the First Refusal Right to any person or entity selected by the Board, including
(without limitation) one or more shareholders of the Corporation. If the
assignee of the Repurchase Right is other than (i) a wholly owned subsidiary of
the Corporation or (ii) the parent corporation owning one hundred percent (100%)
of the Corporation's outstanding capital stock, then such assignee must make a
cash payment to the Corporation, upon the assignment of the Repurchase Right, in
an amount equal to the excess (if any) of (i) the Fair Market Value of the
Purchased Shares at the time subject to the assigned Repurchase Right over (ii)
the aggregate repurchase price payable for the Purchased Shares.

          2.  No Employment or Service Contract. Nothing in this Agreement or in
              ---------------------------------
the Plan shall confer upon Participant any right to continue in Service for any
period of specific

                                       7
<PAGE>

duration or interfere with or otherwise restrict in any way the rights of the
Corporation (or any Parent or Subsidiary employing or retaining Participant) or
of Participant, which rights are hereby expressly reserved by each, to terminate
Participant's Service at any time for any reason, with or without cause.

          3.  Notices. Any notice required to be given under this Agreement
              -------
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

          4.  No Waiver. The failure of the Corporation in any instance to
              ---------
exercise the Repurchase Right or the First Refusal Right shall not constitute a
waiver of any other repurchase rights and/or rights of first refusal that may
subsequently arise under the provisions of this Agreement or any other agreement
between the Corporation and Participant. No waiver of any breach or condition of
this Agreement shall be deemed to be a waiver of any other or subsequent breach
or condition, whether of like or different nature.

          5.  Cancellation of Shares. If the Corporation shall make available,
              ----------------------
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement). Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

     H.  MISCELLANEOUS PROVISIONS
         ------------------------

          1.  Governing Law. This Agreement shall be governed by, and construed
              -------------

     I.   PURPOSE OF THE PLAN

          This 2000 Stock Incentive Plan is intended to promote the interests of
oCen Communications, Inc., a Delaware corporation, by providing eligible persons
in the Corporation's service with the opportunity to acquire a proprietary
interest, or otherwise increase their proprietary interest, in the Corporation
as an incentive for them to remain in such service.

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

     II.  STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into five separate equity incentives
programs:

               -    the Discretionary Option Grant Program under which eligible
persons may, at the discretion of the Plan Administrator, be granted options to
purchase shares of Common Stock,

               -    the Salary Investment Option Grant Program under which
eligible employees may elect to have a portion of their base salary invested
each year in special option grants,

               -    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),

               -    the Automatic Option Grant Program under which eligible non-
employee Board members shall automatically receive option grants at designated
intervals over their period of continued Board service, and

               -    the Director Fee Option Grant Program under which
non-employee Board members may elect to have all or any portion of their annual
retainer fee otherwise payable in cash applied to a special stock option grant.

          B.   The provisions of Articles One and Seven shall apply to all
equity programs under the Plan and shall govern the interests of all persons
under the Plan.
<PAGE>

     III. ADMINISTRATION OF THE PLAN

          A.   The Primary Committee shall have sole and exclusive authority to
administer the Discretionary Option Grant and Stock Issuance Programs with
respect to Section 16 Insiders. Administration of the Discretionary Option Grant
and Stock Issuance Programs with respect to all other persons eligible to
participate in those programs may, at the Board's discretion, be vested in the
Primary Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons. However, any
discretionary option grants or stock issuances for members of the Primary
Committee must be authorized by a disinterested majority of the Board.

          B.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time. The Board may also at any time terminate the functions of
any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

          C.   Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, 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 Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of those programs and any outstanding options
or stock issuances thereunder as it may deem necessary or advisable. Decisions
of the Plan Administrator within the scope of its administrative functions under
the Plan shall be final and binding on all parties who have an interest in the
Discretionary Option Grant and Stock Issuance Programs under its jurisdiction or
any stock option or stock issuance thereunder.

          D.   The Primary Committee shall have the sole and exclusive authority
to determine which Section 16 Insiders and other highly compensated Employees
shall be eligible for participation in the Salary Investment Option Grant
Program for one or more calendar years. However, all option grants under the
Salary Investment Option Grant Program shall be made in accordance with the
express terms of that program, and the Primary Committee shall not exercise any
discretionary functions with respect to the option grants made under that
program.

          E.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

                                       2
<PAGE>

          F.   Administration of the Automatic Option Grant and Director Fee
Option Grant Programs shall be self-executing in accordance with the terms of
those programs, and no Plan Administrator shall exercise any discretionary
functions with respect to any option grants or stock issuances made under those
programs.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                    (i)   Employees,

                    (ii)  non-employee members of the Board or 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.   Only Employees who are Section 16 Insiders or other highly
compensated individuals shall be eligible to participate in the Salary
Investment Option Grant Program.

          C.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary 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 under the Stock Issuance Program, which eligible
persons are to receive such issuances, the time or times when the 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 for such
shares.

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

          E.   The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to (i) those individuals who
first become non-employee Board members on or after the Underwriting Date,
whether through appointment by the Board or election by the Corporation's
stockholders, and (ii) those individuals who continue to serve as non-employee
Board members at one or more Annual Stockholders Meetings held after the
Underwriting Date. A non-employee Board member who has previously been in the
employ of the Corporation (or any Parent or Subsidiary) shall not be eligible to
receive an option grant

                                       3
<PAGE>

under the Automatic Option Grant Program at the time he or she first becomes a
non-employee Board member, but shall be eligible to receive periodic option
grants under the Automatic Option Grant Program while he or she continues to
serve as a non-employee Board member.

          F.   All non-employee Board members shall be eligible to participate
in the Director Fee Option Grant 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, including shares repurchased by the
Corporation on the open market. The number of shares of Common Stock initially
reserved for issuance over the term of the Plan shall not exceed
__________________ shares. Such reserve shall consist of (i) the number of
shares estimated to remain available for issuance, as of the Plan Effective
Date, under the Predecessor Plan as last approved by the Corporation's
stockholders, including the shares subject to outstanding options under the
Predecessor Plan, (ii) plus an additional increase of approximately
___________________ shares to be approved by the Corporation's stockholders
prior to the Underwriting Date.

          B.   The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of January each
calendar year during the term of the Plan, beginning with calendar year 2001, by
an amount equal to ______ percent (___%) of the total number of shares of Common
Stock outstanding on the last trading day in December of the immediately
preceding calendar year, but in no event shall any such annual increase exceed
_________________ shares.

          C.   No one person participating in the Plan may receive stock
options, separately exercisable stock appreciation rights and direct stock
issuances for more than _______________ shares of Common Stock in the aggregate
per calendar year.

          D.   Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent (i) those 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 cancelled or
repurchased by the Corporation at the original issue price paid per share,
pursuant to the Corporation's repurchase rights under the Plan shall be 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. However,
should the exercise price of an option under the Plan be paid with shares of
Common Stock or should shares of Common Stock otherwise issuable under the Plan
be withheld by the Corporation in satisfaction of the withholding taxes incurred
in connection with the exercise of an option or the vesting of a stock issuance
under the Plan, then the number of shares of Common Stock available for issuance
under the Plan shall be reduced by the gross number of shares for which the
option is exercised or which vest under the stock issuance, and not by the net
number of shares of Common Stock issued to the holder of such option or stock

                                       4
<PAGE>

issuance. Shares of Common Stock underlying one or more stock appreciation
rights exercised under Section IV of Article Two, Section III of Article Three,
Section II of Article Five or Section III of Article Six of the Plan shall not
be available for subsequent issuance under the Plan.

          E.   If any change is 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 by the Plan Administrator to (i) the maximum number and/or class of
securities issuable under the Plan, (ii) the maximum number and/or class of
securities for which any one person may be granted stock options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year, (iii) the number and/or class of securities for which grants
are subsequently to be made under the Automatic Option Grant Program to new and
continuing non-employee Board members, (iv) the number and/or class of
securities and the exercise price per share in effect under each outstanding
option under the Plan, (v) the number and/or class of securities and exercise
price per share in effect under each outstanding option incorporated into this
Plan from the Predecessor Plan and (vi) the maximum number and/or class of
securities by which the share reserve is to increase automatically each calendar
year pursuant to the provisions of Section V.B of this Article One. Such
adjustments to the outstanding options are to be effected in a manner which
shall preclude the enlargement or dilution of rights and benefits under such
options. The adjustments determined by the Plan Administrator shall be final,
binding and conclusive.

     withheld by the Corporation by reason of such exercise and (b) the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

          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

                                       6
<PAGE>

Plan Administrator and set forth in the documents evidencing the option.
However, no option shall have a term in excess of ten (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)   Any option outstanding at the time of the Optionee's
     cessation of Service for any reason shall remain exercisable for such
     period of time thereafter as shall be determined by the Plan Administrator
     and set forth in the documents evidencing the option, but no such option
     shall be exercisable after the expiration of the option term.

               (ii)  Any option held by the Optionee at the time of death and
     exercisable in whole or in part at that time may be subsequently exercised
     by the personal representative of the Optionee's estate or by the person or
     persons to whom the option is transferred pursuant to the Optionee's will
     or the laws of inheritance or by the Optionee's designated beneficiary or
     beneficiaries of that option.

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

               (iv)  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 to the extent the option is not otherwise at that time
     exercisable for vested shares.

          2.   The Plan Administrator shall have complete 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 the Optionee's cessation of Service from the limited
     exercise 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

                                       7
<PAGE>

               (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 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 a
holder of record of the purchased shares.

          E.   Repurchase Rights.  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, at the exercise price paid per
share, any or all of those unvested shares. 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.

          F.   Limited Transferability of Options.  During the lifetime of the
               ----------------------------------
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or the laws of inheritance
following the Optionee's death. Non-Statutory Options shall be subject to the
same restriction, except that 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 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 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 this Article Two, 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 Seven shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall not be subject to the terms of this Section II.
                                 ---

                                       8
<PAGE>

          A.   Eligibility.  Incentive Options may only be granted to Employees.
               -----------

          B.   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 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.

          C.   10% Stockholder.  If any Employee to whom an Incentive 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, and the option term shall not exceed five
(5) years measured from the option grant date.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   In the event of any Corporate Transaction, each outstanding
option shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
exercisable for all the shares of Common Stock at the time subject to such
option and may be exercised for any or all of those shares as fully vested
shares of Common Stock. However, an outstanding option shall not become
exercisable on such an accelerated basis if and to the extent: (i) such option
is, in connection with the Corporate Transaction, to be assumed by the successor
corporation (or parent thereof) or (ii) such option is to be replaced with a
cash incentive program of the successor corporation which preserves the spread
existing at the time of the Corporate Transaction on any shares for which the
option is not otherwise at that time exercisable and provides for subsequent
payout in accordance with the same exercise/vesting schedule applicable to those
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 automatically terminate,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate 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 Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                                       9
<PAGE>

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also be made
to (i) the exercise price payable per share under each outstanding option,
provided the aggregate exercise price payable for such securities shall remain
--------
the same, (ii) the maximum number and/or class of securities available for
issuance over the remaining term of the Plan and (iii) the maximum number and/or
class of securities for which any one person may be granted stock options,
separately exercisable stock appreciation rights and direct stock issuances
under the Plan per calendar year and (iv) the maximum number and/or class of
securities by which the share reserve is to increase automatically each calendar
year. To the extent the actual holders of the Corporation's outstanding Common
Stock receive cash consideration for their Common Stock in consummation of the
Corporate Transaction, the successor corporation may, in connection with the
assumption of the outstanding options under the Discretionary Option Grant
Program, 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 Corporate Transaction.

          E.   The Plan Administrator shall have the discretionary authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall, immediately prior to the effective date of
such Corporate Transaction, become exercisable for all the shares of Common
Stock at the time subject to those options and may be exercised for any or all
of those shares as fully vested shares of Common Stock, whether or not those
options are to be assumed in the Corporate Transaction. In addition, the Plan
Administrator shall have the discretionary authority to structure one or more of
the Corporation's repurchase rights under the Discretionary Option Grant Program
so that those rights shall not be assignable in connection with such Corporate
Transaction and shall accordingly terminate upon the consummation of such
Corporate Transaction, and the shares subject to those terminated rights shall
thereupon vest in full.

          F.   The Plan Administrator shall have full power and authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall become exercisable for all the shares of
Common Stock at the time subject to those options in the event the Optionee's
Service is subsequently terminated by reason of an Involuntary Termination
within a designated period (not to exceed eighteen (18) months) following the
effective date of any Corporate Transaction in which those options are assumed
and do not otherwise accelerate. In addition, the Plan Administrator may
structure one or more of the Corporation's repurchase rights so that those
rights shall immediately terminate with respect to any shares held by the
Optionee at the time of his or her Involuntary Termination, and the shares
subject to those terminated repurchase rights shall accordingly vest in full at
that time.

                                      10
<PAGE>

          G.   The Plan Administrator shall have the discretionary authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall, immediately prior to the effective date of
a Change in Control, become exercisable for all the shares of Common Stock at
the time subject to those options and may be exercised for any or all of those
shares as fully vested shares of Common Stock. In addition, the Plan
Administrator shall have the discretionary authority to structure one or more of
the Corporation's repurchase rights under the Discretionary Option Grant Program
so that those rights shall terminate automatically upon the consummation of such
Change in Control, and the shares subject to those terminated rights shall
thereupon vest in full. Alternatively, the Plan Administrator may condition the
automatic acceleration of one or more outstanding options under the
Discretionary Option Grant Program and the termination of one or more of the
Corporation's outstanding repurchase rights under such program upon the
subsequent termination of the Optionee's Service by reason of an Involuntary
Termination within a designated period (not to exceed eighteen (18) months)
following the effective date of such Change in Control.

          H.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction or 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
Nonstatutory Option under the Federal tax laws.

          I.   The outstanding options 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 Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or a 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 grant date.

     V.   STOCK APPRECIATION RIGHTS

          A.   The Plan Administrator shall have full power and authority to
grant to selected Optionees tandem stock appreciation rights and/or limited
stock appreciation rights.

          B.   The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

                    (i)  One or more Optionees may be granted the right,
     exercisable upon such terms as the Plan Administrator may establish, to
     elect between the exercise of the underlying option for shares of Common
     Stock and

                                      11
<PAGE>

     the surrender of that option in exchange for a distribution from the
     Corporation in an amount equal to the excess of (a) the Fair Market Value
     (on the option surrender date) of the number of shares in which the
     Optionee is at the time vested under the surrendered option (or surrendered
     portion thereof) over (b) the aggregate exercise price payable for such
     shares.

                    (ii)  No such option surrender shall be effective unless it
     is approved by the Plan Administrator, either at the time of the actual
     option surrender or at any earlier time. If the surrender is so approved,
     then the distribution to which the Optionee shall be entitled may be made
     in shares of Common Stock valued at Fair Market Value on the option
     surrender date, in cash, or partly in shares and partly in cash, as the
     Plan Administrator shall in its sole discretion deem appropriate.

                    (iii) If the surrender of an option is not approved by the
     Plan Administrator, then the Optionee shall retain whatever rights the
     Optionee had under the surrendered option (or surrendered portion thereof)
     on the option surrender date and may exercise such rights at any time prior
     to the later of (a) five (5) business days after the receipt of the
            -----
     rejection notice or (b) the last day on which the option is otherwise
     exercisable in accordance with the terms of the documents evidencing such
     option, but in no event may such rights be exercised more than ten (10)
     years after the option grant date.

          C.   The following terms shall govern the grant and exercise of
limited stock appreciation rights:

                    (i)   One or more Section 16 Insiders may be granted limited
     stock appreciation rights with respect to their outstanding options.

                    (ii)  Upon the occurrence of a Hostile Take-Over, each
     individual holding one or more options with such a limited stock
     appreciation right shall have the unconditional right (exercisable for a
     thirty (30)-day period following such Hostile Take-Over) to surrender each
     such option to the Corporation. In return for the surrendered option, the
     Optionee shall receive a cash distribution from the Corporation in an
     amount equal to the excess of (A) the Take-Over Price of the shares of
     Common Stock at the time subject to such option (whether or not the option
     is otherwise at that time exercisable for those shares) over (B) the
     aggregate exercise price payable for those shares. Such cash distribution
     shall be paid within five (5) days following the option surrender date.

                    (iii) At the time such limited stock appreciation right is
granted, the Plan Administrator shall pre-approve any subsequent exercise of
that right in accordance with the terms of this Paragraph C. Accordingly, no
further approval of the Plan Administrator or the Board shall be required at the
time of the actual option surrender and cash distribution.

                                 ARTICLE THREE

                    SALARY INVESTMENT OPTION GRANT PROGRAM
                    --------------------------------------

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years (if any) for which the Salary Investment
Option Grant Program is to be in effect and to select the Section 16 Insiders
and other highly compensated Employees eligible to participate in the Salary
Investment Option Grant Program for such calendar year or years.  Each selected
individual who elects to participate in the Salary Investment Option Grant
Program must, prior to the start of each calendar year of participation, file
with the Plan Administrator (or its designate) an irrevocable authorization
directing the Corporation to reduce his or her base salary for that calendar
year by an amount not less than Ten Thousand Dollars ($10,000.00) nor more than
Fifty Thousand Dollars ($50,000.00).   Each individual who files such a timely
authorization shall automatically be granted an option under the Salary
Investment Grant Program on the first trading day in January of the calendar
year for which the salary reduction is to be in effect.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option 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.

          A.   Exercise Price.
               --------------

               1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) 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 be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program. Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   Number of Option Shares.  The number of shares of Common Stock
               -----------------------
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A / (B x 66-2/3%), where

               X is the number of option shares,

                                      13
<PAGE>

               A is the dollar amount by which the Optionee's base salary is to
          be reduced for the calendar year pursuant to his or her election under
          the Salary Investment Option Grant Program, and

               B is the Fair Market Value per share of Common Stock on the
          option grant date.

          C.   Exercise and Term of Options.  The option shall become
               ----------------------------
exercisable in a series of twelve (12) successive equal monthly installments
upon the Optionee's completion of each calendar month of Service in the calendar
year for which the salary reduction is in effect. Each option shall have a
maximum term of ten (10) years measured from the option grant date.

          D.   Effect of Termination of Service.  Should the Optionee cease
               --------------------------------
Service for any reason while holding one or more options under this Article
Three, then each such option shall remain exercisable, for any or all of the
shares for which the option is exercisable at the time of such cessation of
Service, until the earlier of (i) the expiration of the ten (10)-year option
                   -------
term or (ii) the expiration of the three (3)-year period measured from the date
of such cessation of Service. Should the Optionee die while holding one or more
options under this Article Three, then each such option may be exercised, for
any or all of the shares for which the option is exercisable at the time of the
Optionee's cessation of Service (less any shares subsequently purchased by
Optionee prior to death), by the personal representative of the Optionee's
estate or by the person or persons to whom the option is transferred pursuant to
the Optionee's will or the laws of inheritance or by the designated beneficiary
or beneficiaries of the option. Such right of exercise shall lapse, and the
option shall terminate, upon the earlier of (i) the expiration of the ten
                                 -------
(10)-year option term or (ii) the three (3)-year period measured from the date
of the Optionee's cessation of Service. However, the option shall, immediately
upon the Optionee's cessation of Service for any reason, terminate and cease to
remain outstanding with respect to any and all shares of Common Stock for which
the option is not otherwise at that time exercisable.

     III. CORPORATE TRANSACTION/ CHANGE IN CONTROL/ HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee
remains in Service, each outstanding option held by such Optionee under this
Salary Investment Option Grant Program shall automatically accelerate so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become exercisable for all the shares of Common Stock at the time
subject to such option and may be exercised for any or all of those shares as
fully vested shares of Common Stock. Each such outstanding option shall
terminate immediately following the Corporate Transaction, except to the extent
assumed by the successor corporation (or parent thereof) in such Corporate
Transaction. Any option so assumed and shall remain exercisable for the fully
vested shares until the earlier of (i) the expiration of the ten (10)-year
option term or (ii) the expiration of the three (3)-year period measured from
the date of the Optionee's cessation of Service.

                                      14
<PAGE>

          B.   In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Salary
Investment Option Grant Program shall automatically accelerate so that each such
option shall, immediately prior to the effective date of the Change in Control,
become exercisable for all the shares of Common Stock at the time subject to
such option and may be exercised for any or all of those shares as fully vested
shares of Common Stock. The option shall remain so exercisable until the
earliest to occur of (i) the expiration of the ten (10)-year option term, (ii)
--------
the expiration of the three (3)-year period measured from the date of the
Optionee's cessation of Service, (iii) the termination of the option in
connection with a Corporate Transaction or (iv) the surrender of the option in
connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each
outstanding option granted him or her under the Salary Investment Option Grant
Program. The Optionee shall in return be entitled to a cash distribution from
the Corporation in an amount equal to the excess of (i) the Take-Over Price of
the shares of Common Stock at the time subject to the surrendered option
(whether or not the option is otherwise at the time exercisable for those
shares) over (ii) the aggregate exercise price payable for such shares. Such
cash distribution shall be paid within five (5) days following the surrender of
the option to the Corporation. The Primary Committee shall, at the time the
option with such limited stock appreciation right is granted under the Salary
Investment Option Grant Program, pre-approve any subsequent exercise of that
right in accordance with the terms of this Paragraph C. Accordingly, no further
approval of the Primary Committee or the Board shall be required at the time of
the actual option surrender and cash distribution.

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to 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 Corporate Transaction, the
successor corporation may, in connection with the assumption of the outstanding
options under the Salary Investment Option Grant Program, 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 Corporate Transaction.

          E.   The grant of options under the Salary Investment Option Grant
Program 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.

                                      15
<PAGE>

     IV.  REMAINING TERMS

          The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

                            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.  Shares of Common Stock may also be
issued under the Stock Issuance Program pursuant to share right awards which
entitle the recipients to receive those shares upon the attainment of designated
performance goals.

          A.   Purchase Price.
               --------------

               1.   The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

               2.   Subject to the provisions of Section I of Article Seven,
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. The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program shall be
determined by the Plan Administrator and incorporated into the Stock Issuance
Agreement. Shares of Common Stock may also be issued under the Stock Issuance
Program pursuant to share right awards which entitle the recipients to receive
those shares upon the attainment of designated performance goals.

               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

                                      17
<PAGE>

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.

               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 cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

               5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock which
would otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives 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.

               6.   Outstanding share right awards under the Stock Issuance
Program shall automatically terminate, and no shares of Common Stock shall
actually be issued in satisfaction of those awards, if the performance goals
established for such awards are not attained. The Plan Administrator, however,
shall have the discretionary authority to issue shares of Common Stock under one
or more outstanding share right awards as to which the designated performance
goals have not been attained.

     II.  CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   All of the Corporation's outstanding repurchase rights under the
Stock Issuance Program shall terminate automatically, and all the shares of
Common Stock subject to those terminated rights shall immediately vest in full,
in the event of any Corporate Transaction, except to the extent (i) those
repurchase rights are to be assigned to the successor corporation (or parent
thereof) in connection with such Corporate Transaction or (ii) such accelerated
vesting is precluded by other limitations imposed in the Stock Issuance
Agreement.

                                      18
<PAGE>

          B.   The Plan Administrator shall have the discretionary authority to
structure one or more of the Corporation's repurchase rights under the Stock
Issuance Program so that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated 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
Corporate Transaction in which those repurchase rights are assigned to the
successor corporation (or parent thereof).

          C.   The Plan Administrator shall also have the discretionary
authority to structure one or more of the Corporation's repurchase rights under
the Stock Issuance Program so that those rights shall automatically terminate in
whole or in part, and the shares of Common Stock subject to those terminated
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.

     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.

                                 ARTICLE FIVE

                        AUTOMATIC OPTION GRANT PROGRAM
                        ------------------------------

     I.   OPTION TERMS

          A.   Grant Dates.  Option grants shall be made on the dates specified
               -----------
below:

               1.   Each individual who is first elected or appointed as a
non-employee Board member at any time on or after the Underwriting Date shall
automatically be granted, on the date of such initial election or appointment, a
Non-Statutory Option to purchase ______________ shares of Common Stock, provided
that individual has not previously been in the employ of the Corporation or any
Parent or Subsidiary.

               2.   On the date of each Annual Stockholders Meeting held after
the Underwriting Date, each individual who is to continue to serve as a
non-employee Board member, whether or not that individual is standing for
re-election to the Board at that particular Annual Meeting, shall automatically
be granted a Non-Statutory Option to purchase _________ shares of Common Stock,
provided such individual has served as a non-employee Board member for at least
six (6) months. There shall be no limit on the number of such ___________-share
option grants any one non-employee Board member may receive over his or her
period of Board service, and non-employee Board members who have previously been
in the employ of the Corporation (or any Parent or Subsidiary) or who have
otherwise received one or more stock option grants from the Corporation prior to
the Underwriting Date shall be eligible to receive one or more such annual
option grants over their period of continued Board service.

          B.   Exercise Price.
               --------------

               1.   The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the option
grant date.

               2.   The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   Option Term.  Each option shall have a term of ten (10) years
               -----------
measured from the option grant date.

          D.   Exercise and Vesting of Options.  Each option shall be
               -------------------------------
immediately exercisable for any or all of the option shares. However, any
unvested shares purchased under the option shall be subject to repurchase by the
Corporation, at the exercise price paid per share, upon the Optionee's cessation
of Board service prior to vesting in those shares. The shares subject to each
initial ______________-share grant shall vest, and the Corporation's repurchase

                                      20
<PAGE>

right shall lapse, in a series of four (4) successive equal annual installments
upon the Optionee's completion of each year of service as a Board member over
the four (4)-year period measured from the option grant date. The shares subject
to each annual ____________-share option grant shall vest in one installment
upon the Optionee's completion of the one (1)-year period of service measured
from the grant date.

          E.   Limited Transferability of Options.  Each option under this
               ----------------------------------
Article Five 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 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
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. The Optionee may also designate one
or more persons as the beneficiary or beneficiaries of his or her outstanding
options under this Article Five, 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.

          F.   Termination of Board Service.  The following provisions shall
               ----------------------------
govern the exercise of any options held by the Optionee at the time the Optionee
ceases to serve as a Board member:

                    (i)   The Optionee (or, in the event of Optionee's death,
     the personal representative of the Optionee's 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 designated beneficiary or beneficiaries
     of such option) shall have a twelve (12)-month period following the date of
     such cessation of Board service in which to exercise each such option.

                    (ii)  During the twelve (12)-month exercise period, the
     option may not be exercised in the aggregate for more than the number of
     vested shares of Common Stock for which the option is exercisable at the
     time of the Optionee's cessation of Board service.

                    (iii) Should the Optionee cease to serve as a Board member
     by reason of death or Permanent Disability, then all shares at the time
     subject to the option shall immediately vest so that such option may,
     during the twelve (12)-month exercise period following such cessation of
     Board service, be exercised for all or any portion of those shares as fully
     vested shares of Common Stock.

                                      21
<PAGE>

                    (iv) In no event shall the option remain exercisable after
     the expiration of the option term. Upon the expiration of the twelve
     (12)-month 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 Board service
     for any reason other than death or Permanent Disability, terminate and
     cease to be outstanding to the extent the option is not otherwise at that
     time exercisable for vested shares.

     II.  CORPORATE TRANSACTION/ CHANGE IN CONTROL/ HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee
remains a Board member, the shares of Common Stock at the time subject to each
outstanding option under this Automatic Option Grant Program but not otherwise
vested shall automatically vest in full so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
exercisable for all the option shares as fully vested shares of Common Stock and
may be exercised for any or all of those vested shares. Immediately following
the consummation of the Corporate Transaction, each automatic option grant shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof).

          B.   In connection with any Change in Control while the Optionee
remains a Board member, the shares of Common Stock at the time subject to each
outstanding option under this Automatic Option Grant Program but not otherwise
vested 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 the option shares as fully vested shares of Common Stock and
may be exercised for any or all of those vested shares. Each such option shall
remain exercisable for such fully vested option shares until the expiration or
sooner termination of the option term or the surrender of the option in
connection with a Hostile Take-Over.

          C.   All outstanding repurchase rights under this under this Automatic
Option Grant Program shall automatically terminate, and the shares of Common
Stock subject to those terminated rights shall immediately vest in full, in the
event of any Corporate Transaction or Change in Control.

          D.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding options under this Automatic Option Grant Program. The
Optionee shall in return be entitled to a cash distribution from the Corporation
in an amount equal to the excess of (i) the Take-Over Price of the shares of
Common Stock at the time subject to each surrendered option (whether or not the
Optionee is otherwise at the time vested in those shares) over (ii) the
aggregate exercise price payable for such shares. Such cash distribution shall
be paid within five (5) days following the surrender of the option to the
Corporation. No approval or consent of the Board or any Plan Administrator shall
be required at the time of the actual option surrender and cash distribution.

                                      22
<PAGE>

          E.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to 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 Corporate Transaction, the
successor corporation may, in connection with the assumption of the outstanding
options under the Automatic Option Grant Program, 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 Corporate Transaction.

          F.   The grant of options under the Automatic Option Grant Program
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.

     III. REMAINING TERMS

          The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

                       DIRECTOR FEE OPTION GRANT PROGRAM
                       ---------------------------------

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years for which the Director Fee Option Grant
Program is to be in effect.  For each such calendar year the program is in
effect, each non-employee Board member may irrevocably elect to apply all or any
portion of the annual retainer fee otherwise payable in cash for his or her
service on the Board for that year to the acquisition of a special option grant
under this Director Fee Option Grant Program.  Such election must be filed with
the Corporation's Chief Financial Officer prior to the first day of the calendar
year for which the annual retainer fee which is the subject of that election is
otherwise payable.  Each non-employee Board member who files such a timely
election shall automatically be granted an option under this Director Fee Option
Grant Program on the first trading day in January in the calendar year for which
the annual retainer fee which is the subject of that election would otherwise be
payable in cash.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option governed by the terms and
conditions specified below.

          A.   Exercise Price.
               --------------

               1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) 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 be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program. Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   Number of Option Shares.  The number of shares of Common Stock
               -----------------------
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A / (B x 66-2/3%), where

               X is the number of option shares,

               A is the portion of the annual retainer fee subject to the
          non-employee Board member's election under this Director Fee Option
          Grant Program, and

                                      24
<PAGE>

               B is the Fair Market Value per share of Common Stock on the
          option grant date.

          C.   Exercise and Term of Options.  The option shall become
               ----------------------------
exercisable in a series of twelve (12) equal monthly installments upon the
Optionee's completion of each calendar month of Board service during the
calendar year for which the retainer fee election is in effect. Each option
shall have a maximum term of ten (10) years measured from the option grant date.

          D.   Limited Transferability of Options.  Each option under this
               ----------------------------------
Article Six 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 such family members or to Optionee's former spouse,
to the extent such assignment is in connection with 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
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. The Optionee may also designate one
or more persons as the beneficiary or beneficiaries of his or her outstanding
options under this Article Six, 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.

          E.   Termination of Board Service.  Should the Optionee cease Board
               ----------------------------
service for any reason (other than death or Permanent Disability) while holding
one or more options under this Director Fee Option Grant Program, then each such
option shall remain exercisable, for any or all of the shares for which the
option is exercisable at the time of such cessation of Board service, until the
earlier of (i) the expiration of the ten (10)-year option term or (ii) the
-------
expiration of the three (3)-year period measured from the date of such cessation
of Board service. However, each option held by the Optionee under this Director
Fee Option Grant Program at the time of his or her cessation of Board service
shall immediately terminate and cease to remain outstanding with respect to any
and all shares of Common Stock for which the option is not otherwise at that
time exercisable.

          F.   Death or Permanent Disability.  Should the Optionee's service as
               -----------------------------
a Board member cease by reason of death or Permanent Disability, then each
option held by such Optionee under this Director Fee Option Grant Program shall
immediately become exercisable for all the shares of Common Stock at the time
subject to that option, and the option may be exercised for any or all of those
shares as fully vested shares until the earlier of (i) the expiration of the ten
                                        -------
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from

                                      25
<PAGE>

the date of such cessation of Board service.  To the extent such option is held
by the Optionee at the time of his or death, that option may be exercised by the
personal representative of the Optionee's estate or by the person or persons to
whom the option is transferred pursuant to the Optionee's will or the laws of
inheritance or by the designated beneficiary or beneficiaries of such option.

               Should the Optionee die after cessation of Board service but
while holding one or more options under this Director Fee Option Grant Program,
then each such option may be exercised, for any or all of the shares for which
the option is exercisable at the time of the Optionee's cessation of Board
service (less any shares subsequently purchased by Optionee prior to death), by
the personal representative of the Optionee's estate or by the person or persons
to whom the option is transferred pursuant to the Optionee's will or the laws of
inheritance or by the designated beneficiary or beneficiaries of such option.
Such right of exercise shall lapse, and the option shall terminate, upon the
earlier of (i) the expiration of the ten (10)-year option term or (ii) the three
-------
(3)-year period measured from the date of the Optionee's cessation of Board
service.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee
remains a Board member, each outstanding option held by such Optionee under this
Director Fee Option Grant Program shall automatically accelerate so that each
such option shall, immediately prior to the effective date of the Corporate
Transaction, become exercisable for all the shares of Common Stock at the time
subject to such option and may be exercised for any or all of those shares as
fully vested shares of Common Stock. Each such outstanding option shall
terminate immediately following the Corporate Transaction, except to the extent
assumed by the successor corporation (or parent thereof) in such Corporate
Transaction. Any option so assumed and shall remain exercisable for the fully
vested shares until the earlier of (i) the expiration of the ten (10)-year
                        -------
option term or (ii) the expiration of the three (3)-year period measured from
the date of the Optionee's cessation of Board service.

          B.   In the event of a Change in Control while the Optionee remains a
Board member, each outstanding option held by such Optionee under this Director
Fee Option Grant Program shall automatically accelerate so that each such option
shall, immediately prior to the effective date of the Change in Control, become
exercisable for all the shares of Common Stock at the time subject to such
option and may be exercised for any or all of those shares as fully vested
shares of Common Stock. The option shall remain so exercisable until the
earliest to occur of (i) the expiration of the ten (10)-year option term, (ii)
--------
the expiration of the three (3)-year period measured from the date of the
Optionee's cessation of Board service, (iii) the termination of the option in
connection with a Corporate Transaction or (iv) the surrender of the option in
connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each
outstanding option granted him or her under the Director Fee Option Grant
Program. The Optionee shall in return be

                                      26
<PAGE>

entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the option is otherwise at
the time exercisable for those shares) over (ii) the aggregate exercise price
payable for such shares. Such cash distribution shall be paid within five (5)
days following the surrender of the option to the Corporation. No approval or
consent of the Board or any Plan Administrator shall be required at the time of
the actual option surrender and cash distribution.

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.

shares of its own common stock with a fair market value equivalent to the cash
consideration paid per share of Common Stock in such Corporate Transaction.

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.  REMAINING TERMS

     I.   FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest-bearing promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  In no event 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
such shares) plus (ii) any Federal, state and local income and employment tax
liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

          A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or the issuance or vesting of such shares under the

local income and employment tax withholding requirements.

Plan (other than the options granted or the shares issued under the Automatic
Option Grant or Director Fee Option Grant Program) with the right to use shares
of Common Stock in satisfaction of all or part of the Withholding Taxes to which
such holders may become subject in connection with the exercise of their options
or the vesting of their shares. Such right may be provided to any such holder in
either or both of the following formats:

               Stock Withholding:  The election to have the Corporation
               -----------------
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such Non-Statutory Option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

               Stock Delivery:  The election to deliver to the Corporation, at
               --------------
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Withholding
Taxes) with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

     III. EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective immediately on the Plan Effective
Date. However, the Salary Investment Option Grant Program and the Director Fee
Option Grant Program shall not be implemented until such time as the Primary
Committee may deem appropriate. Options may be granted under the Discretionary
Option Grant at any time on or after the Plan Effective Date, and the initial
option grants under the Automatic Option Grant Program shall also be made on the
Plan Effective Date to any non-employee Board members eligible for such grants
at that time. However, no options 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 Plan Effective Date, then all options previously
granted under this Plan shall terminate and cease to be outstanding, and no
further options shall be granted and no shares shall be issued under the Plan.

          B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further option grants or direct stock issuances shall be made under the
Predecessor Plan after the Plan Effective Date. All options outstanding under
the Predecessor Plan on the Plan Effective Date shall be incorporated into the
Plan at that time and shall be treated as outstanding options under the Plan.
However, each outstanding option so incorporated shall continue to be governed
solely by the terms of the documents evidencing such option, and no provision of
the Plan shall be deemed to affect or otherwise modify the rights or obligations
of the holders of such incorporated options with respect to their acquisition of
shares of Common Stock.

          C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated from
the Predecessor Plan which do not otherwise contain such provisions.

          D.   The Plan shall terminate upon the earliest to occur of (i)
                                                 --------
____________, (ii) the date on which all shares available for issuance under the
Plan shall have been issued as fully vested shares or (iii) the termination of
all outstanding options in connection with a Corporate Transaction. Should the
Plan terminate on ______________, then all option grants and unvested stock
issuances outstanding at that time shall continue to have force and effect in
accordance with the provisions of the documents evidencing such grants or
issuances.

     IV.  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 stock 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 or regulations.

                                      29
<PAGE>

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and Salary Investment Option Grant Programs and
shares of Common Stock may be issued under the Stock Issuance Program that are
in each instance in excess of the number of shares then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained 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 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.

     V.   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.

     VI.  REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted 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 stock options
granted under it and the shares of Common Stock issued pursuant to it.

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

     VII. NO EMPLOYMENT/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.
