POLYCOM, INC. 1996 STOCK INCENTIVE PLAN
  
  (AS AMENDED THROUGH MAY 20, 2003)    
    

        The following constitute the provisions of the 1996 Stock Incentive Plan (herein called the "Plan") of Polycom, Inc. (herein called the "Corporation"). 

ARTICLE ONE

GENERAL PROVISIONS  

	I.
	PURPOSE
OF THE PLAN 

        This
1996 Stock Incentive Plan is intended to promote the interests of Polycom, Inc., a Delaware corporation, by providing eligible persons 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 the service of the Corporation. 

        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 three (3) separate equity programs: 

          (i)  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, 

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

        (iii)  the
Automatic Option Grant Program under which Eligible Directors shall automatically receive option grants at periodic intervals to purchase shares of Common Stock. 

        B.    The
Discretionary Option Grant and Stock Issuance Programs became effective immediately upon the Plan Effective Date, and the Automatic Option Grant Program became
effective upon the Underwriting Date. 

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

	III.
	ADMINISTRATION
OF THE PLAN 

        A.    Prior
to the Section 12(g) Registration Date, the Discretionary Option Grant and Stock Issuance Programs were administered by the Board. Beginning with the
Section 12(g) Registration Date, 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. 

        B.    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. The members of the
Secondary Committee may be Board members who are also Employees. 

        C.    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. 

 

        D.    Each
Plan Administrator shall, within the scope of its administrative functions under the Plan, have full power and authority 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 such 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 or Stock Issuance Program under its jurisdiction or any stock option or stock issuance
thereunder. 

        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. 

        F.     Administration
of the Automatic Option Grant Program shall be self-executing in accordance with the terms of that program, and no Plan Administrator shall
exercise any discretionary functions with respect to option grants made thereunder. 

	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.    Each
Plan Administrator shall, within the scope of its administrative jurisdiction under the Plan, have full authority (subject to the provisions of the Plan) to
determine, (i) with respect to the option grants under the Discretionary Option Grant Program, which eligible persons are to receive option grants, the time or times when such option 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 at which 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 stock issuances, the time or times when such issuances are to be made, the number of shares to be issued to each
Participant, the vesting schedule (if any) applicable to the issued shares and the consideration to be paid for such shares. 

        C.    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. 

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

2

 

Parent
or Subsidiary) or has otherwise received a prior stock option grant from the Corporation. A non-employee Board member who first joins the Board after the Underwriting Date shall not
be eligible to receive an initial option grant under the Automatic Option Grant Program if such individual has previously been in the employ of the Corporation (or any Parent or Subsidiary).
Non-employee Board members who have previously been in the employ of the Corporation (or any Parent or Subsidiary) or who have previously received a stock option grant from the Corporation
shall, however, be eligible to receive one or more annual option grants under the Automatic Option Grant Program over their period of continued Board service. 

	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 maximum number of shares of Common Stock which may be issued over the term of the Plan shall not exceed approximately 23,150,000 shares. 

        B.    No
one person participating in the Plan may receive options, separately exercisable stock appreciation rights and direct stock issuances for more than 600,000 shares of
Common Stock in the aggregate per calendar year, beginning with the 1996 calendar year. 

        C.    No
more than ten percent (10%) of the maximum number of shares which may be issued under the Plan may be issued pursuant to the Stock Issuance Program. 

        D.    Shares
of Common Stock subject to outstanding options shall be available for subsequent issuance under the Plan to the extent (i) the options (including any
options incorporated from the Predecessor Plan) expire or terminate for any reason prior to exercise in full or (ii) the options are canceled in accordance with the cancellation-regrant
provisions of Article Two. In addition, any unvested shares issued under the Plan and subsequently repurchased by the Corporation, at the option exercise or direct 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 (including any option incorporated from the
Predecessor 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 issuance. 

        E.    Should
any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan, (ii) the maximum number and/or class of securities for which any one person may be granted options, separately exercisable stock appreciation rights and direct stock
issuances per calendar year, (iii) the number and/or class of securities for which automatic option grants are to be made subsequently per Eligible Director under the Automatic Option Grant
Program and (iv) the number and/or class of securities and the exercise price per share in effect under each outstanding option (including any option incorporated from the Predecessor Plan) in
order to prevent the dilution or enlargement of benefits thereunder. The adjustments determined by the Plan Administrator shall be final, binding and conclusive.

ARTICLE TWO

DISCRETIONARY OPTION GRANT PROGRAM  

	I.
	OPTION
TERMS 

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

        A.    EXERCISE
PRICE. 

          (i)  The
exercise 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 option grant date. 

         (ii)  The
exercise price shall become immediately due upon exercise of the option and shall, subject to the provisions of Section I of Article Five and the documents
evidencing the option, be payable in one or more of the forms specified below: 

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

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

         (v)  to
the extent the option is exercised for vested shares, through a special sale and remittance procedure pursuant to which the Optionee shall concurrently provide
irrevocable written instructions to (a) a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds
available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes
required to be 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 transaction. 

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

        B.    EXERCISE
AND TERM OF OPTIONS. Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by the Plan
Administrator and set forth in the documents evidencing the option. However, no option shall have a term in excess of seven (7) years measured from the option grant date. 

        C.    EFFECT
OF TERMINATION OF SERVICE. 

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

        (1)   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. 

        (2)   Any
option exercisable in whole or in part by the Optionee at the time of death may be exercised subsequently 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 in accordance with the laws of descent and distribution. 

4

 

        (3)   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. 

        (4)   Should
the Optionee's Service be terminated for Misconduct, then all outstanding options held by the Optionee shall terminate immediately and cease to be outstanding. 

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

        (1)   extend
the period of time for which the option is to remain exercisable following the Optionee's cessation of Service from the 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 date of the option term, and/or 

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

        D.    STOCKHOLDER
RIGHTS. The holder of an option shall have no stockholder rights with respect to the shares subject to the option until such person shall have exercised the
option, paid the exercise price and become 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 by the laws of descent and distribution following the Optionee's death. However, Non-Statutory Options may, in connection with the Optionee's estate
plan, be assigned in whole or in part during the Optionee's lifetime to one or more members of the Optionee's immediate family or to a trust established exclusively for one or more such family
members; provided, however, that unless the Plan Administrator determines otherwise in a stock option agreement, Non-Statutory Options provided to Optionees employed by the Company's
European subsidiaries are not so transferable. 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. 

	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 Five
shall be applicable to 

5

 

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. 

        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
(1) calendar year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the exercisability of such options as Incentive Options shall be applied on the basis of the order in which such options are granted. 

        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 fully exercisable with respect to the total number of 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 so accelerate 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 on
the unvested option shares at the time of the Corporate Transaction and provides for subsequent payout in accordance with the same vesting schedule applicable to such option. 

        B.    All
outstanding repurchase rights shall also terminate automatically, and the shares of Common Stock subject to those terminated rights shall immediately vest in full, in
the event of any Corporate Transaction, except to the extent those repurchase rights are to be assigned to the successor corporation (or parent thereof) in connection with such Corporate Transaction. 

        C.    The
Plan Administrator shall have the discretion, exercisable either at the time the option is granted or at any time while the option remains outstanding, to provide for
the automatic acceleration of one or more outstanding options (and the automatic termination of one or more outstanding repurchase rights with the immediate vesting of the shares of Common Stock
subject to those rights) upon the occurrence of a Corporate Transaction, whether or not those options are to be assumed (or those repurchase rights are to be assigned) in the Corporate Transaction. 

        D.    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). 

        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 (i) the number and class of securities available for issuance under the Plan following the consummation of such Corporate Transaction,
(ii) the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable 

6

 

for
such securities shall remain the same 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. 

        F.     The
Plan Administrator shall have full power and authority to grant options under the Discretionary Option Grant Program which will automatically accelerate in whole or
in part should the Optionee's Service subsequently terminate by reason of an Involuntary Termination within a designated period (not to exceed twelve (12) months) following the effective date
of any Corporate Transaction in which those options are assumed or replaced and do not otherwise accelerate. Any options so accelerated shall remain exercisable for fully-vested shares until the
EARLIER of (i) the expiration of the option term or (ii) the expiration of the one (1)-year period measured from the effective date of the Involuntary Termination. In
addition, the Plan Administrator may provide that one or more of the Corporation's outstanding repurchase rights with respect to shares held by the Optionee at the time of such Involuntary Termination
shall immediately terminate in whole or in part, and the shares subject to those terminated rights shall accordingly vest. 

        G.    The
Plan Administrator shall have full power and authority to grant options under the Discretionary Option Grant Program which will automatically accelerate in whole or
in part should the Optionee's Service subsequently terminate by reason of an Involuntary Termination within a designated period (not to exceed twelve (12) months) following the effective date
of any Change in Control. Each option so accelerated shall remain exercisable for fully-vested shares until the EARLIER of (i) the expiration of the option term or (ii) the expiration of
the one (1)-year period measured from the effective date of the Involuntary Termination. In addition, the Plan Administrator may provide that one or more of the Corporation's outstanding
repurchase rights with respect to shares held by the Optionee at the time of such Involuntary Termination shall immediately terminate in whole or in part, and the shares subject to those terminated
rights shall accordingly vest. 

        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 Non-Statutory Option under the Federal tax laws. 

        I.     The
grant of options under the Discretionary 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. 

	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 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. However, any repricing of stock options, effected
either by reducing the exercise price of outstanding options or canceling outstanding options and granting replacement options with a lower exercise price, shall require the approval of the holders of
a majority of the Corporation's voting shares, with the sole exception of that certain exchange offer to be commenced as soon as is reasonably practicable following May 20, 2003, pursuant to
which holders of options to purchase a maximum of 7,000,000 shares of the Corporation's Common Stock with an exercise price per share of at least ten percent (10%) higher than the closing price of a
share of the Company's Common Stock on the Nasdaq National Market on the trading day prior to the commencement of the exchange offer, shall be offered the opportunity to elect to cancel such options 

7

 

(the
"Cancelled Options"), in exchange for the grant of replacement options to purchase 0.80 shares of the Corporation's Common Stock for each share under the Cancelled Options (the "Replacement
Options"), with such Replacement Options to be granted no less than six months and one day following the cancellation of the Cancelled Options, at a price equal to the fair market value of the
Corporation's Common Stock on such date of grant (the "New Grant Date"). Each Replacement Option will have a term equal to the lesser of (i) the remaining term of the Cancelled Option, or
(ii) five and one-half (51/2) years. The vesting commencement date and vesting schedule for each Replacement Option will be the same as for the Cancelled Option which
it replaces, subject to adjustment for any shares previously exercised, except that vesting will be suspended during the period between the cancellation date of the Cancelled Options and the New Grant
Date. Further, optionholders who receive Replacement Options will be prohibited from exercising those Replacement Options for an additional six months following the New Grant Date. Executive Officers
and Directors of the Corporation shall not participate in this exchange offer, and this exchange offer will be structured so that the Corporation avoids incurring financial accounting charges. 

	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 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. 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 rejected 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, to the extent the option is at
the time exercisable for vested shares of Common Stock. 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 

8

 

Common
Stock which are at the time vested under each surrendered option (or surrendered portion thereof) over (B) the aggregate exercise price payable for such shares. Such cash distribution
shall be paid within five (5) days following the option surrender date. 

        (iii)  The
Plan Administrator shall pre-approve, at the time the limited stock appreciation right is granted, the subsequent exercise of that right in accordance
with the terms of the grant and the provisions of this Section V.C. No additional approval of the Plan Administrator or the Board shall be required at the time of the actual option surrender
and cash distribution. 

        (iv)  The
balance of the option (if any) shall continue in full force and effect in accordance with the documents evidencing such option. 

ARTICLE THREE

STOCK ISSUANCE PROGRAM  

	I.
	STOCK
ISSUANCE TERMS 

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

        A.    PURCHASE
PRICE. 

          (i)  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. 

         (ii)  Subject
to the provisions of Section I of Article Five, shares of Common Stock may be issued under the Stock Issuance Program for any of the following items of

        (1)   the

        (2)   the
number of installments in which the shares are to vest, 

        (3)   the
interval or intervals (if any) which are to lapse between installments, and 

        (4)   the
effect which death, Permanent Disability or other event designated by the Plan Administrator is to have upon the vesting schedule, shall be determined by the Plan
Administrator and incorporated into the Stock Issuance Agreement. 

         (ii)  Any

receive with respect to the Participant's unvested shares of Common Stock by reason of any stock dividend, stock split, recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration shall

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. 

        (iii)  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. 

        (iv)  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. 

         (v)  The
Plan Administrator may in its discretion waive the surrender and cancellation of one or more unvested shares of Common Stock (or other assets attributable thereto)
which would otherwise occur upon the 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.

        B.    The
Plan Administrator shall have the discretionary authority, exercisable either at the time the unvested shares are issued or any time while the Corporation's
repurchase/cancellation rights remain outstanding under the Stock Issuance Program, to provide 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

ARTICLE FOUR

AUTOMATIC OPTION GRANT PROGRAM  

	I.
	OPTION
TERMS 

        A.    GRANT
DATES. Option grants shall be made on the dates specified below: 

          (i)  On
the date of each Annual Stockholders Meeting held on or after May 20, 2003, each non-employee member of the Board who is to continue to serve on
the Board (an "Eligible Director"), whether or not that Eligible Director is standing for re-election to the Board at that particular Annual Meeting, shall automatically be granted a
Non-Statutory Option to purchase an amount equal to 25,000 shares of Common Stock. There shall be no limit on the number of such option grants any one Eligible Director may receive over
his or her period of Board service, and Eligible Directors who have previously been in the employ of the Corporation (or any Parent or Subsidiary) or who have otherwise received a stock option grant
from the Corporation shall be eligible to receive such option grants over their period of continued Board service. Each individual serving as a non-employee Board member shall, upon the
date such individual joins the Board of Directors, be automatically granted on such date a non-statutory option to purchase 30,000 shares if joining between January 27, 1999 and
May 17, 2001 or 60,000 shares if joining on or after May 17, 2001 (a "Primary Grant"), provided such individual (i) had not previously been in the employ of the Corporation (or
any parent or Subsidiary) and (ii) had not otherwise received a prior stock option grant from the Corporation. 

         (ii)  Each
Eligible Director on October 26, 1999 shall automatically be granted a Non-Statutory Option to purchase a number of shares of Common Stock equal
to (x) 30,000 minus (y) the number of shares of Common Stock Options granted to such individual since the prior Annual Stockholders Meeting and including the grant at such meeting (the
"Interim Option"). 

        (iii)  Each
individual serving as a non-employee Board member on the Underwriting Date and each Eligible Director elected to the Board prior to January 26,
1999 was automatically granted, on such date, a Non-Statutory Option to purchase 40,000 shares of Common Stock (an "Initial Grant"), provided such individual (i) had not previously
been in the employ of the Corporation (or any Parent or Subsidiary) and (ii) had not otherwise received a prior stock option grant from the Corporation, except that prior to the 1998 Annual
Meeting such Initial grant was for 32,000 shares instead of 40,000. On every Annual Shareholder Meeting after the Underwriting Date but on or prior to January 26, 1999, each Eligible Director
was granted a Non-Statutory Option for 10,000 shares of Common Stock, provided such individual was an Eligible Director for at least six (6) months, except that prior to the 1998
Annual Meeting, such option was to purchase 8,000 shares, not 10,000. After January 26, 1999 and prior to October 26, 1999, Eligible Directors were granted a Non-Statutory
Option to purchase 7,500 shares of Common Stock on the date of each Annual Shareholders Meeting and grants of Non-Statutory Options to purchase 7,500 shares of Common Stock on the next
three (3) three (3) month anniversaries following each applicable Annual Shareholders Meeting. The automatic annual grant of 30,000 shares of Common Stock is intended to replace these
previous automatic quarterly grants. 

11

 

        B.    EXERCISE
PRICE. 

          (i)  The
exercise price per share for any option grant under this Article Four shall be equal to one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date. 

         (ii)  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 granted on or after May 17, 2001 shall have a term of seven (7) years measured from the grant date. Each option granted between
October 26, 1999 and May 17, 2001 shall have a term of five (5) years measured from the grant date. The Interim Option shall have a term of five (5) years from the date of
the 1999 Annual Stockholders Meeting. Each option granted on or after January 26, 1999 and on or before October 26, 1999 shall have a term of two (2) years measured from the
option grant date. Each option granted prior to January 26, 1999 shall have a term of ten (10) years from its date of grant. 

        D.    EXERCISE
AND VESTING OF OPTIONS. Automatic option grants made on the date of each Annual Stockholders Meeting held on or after May 20, 2003 shall vest and become
exercisable on the first anniversary of their grant date, provided the Optionee remains a Board member on such date. Each Interim Option shall vest and become exercisable on the first anniversary of
the 1999 Annual Shareholders Meeting, provided the Optionee remains a Board member on such date. Each option granted on or after January 26, 1999 and on or before October 26, 1999 shall
be fully vested and immediately exercisable on the option grant date for any or all of the option shares. Any shares purchased under an option granted prior to January 26, 1999 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. Each Initial Grant and each Primary Grant shall
vest, and the Corporation's repurchase right shall lapse, in a series of four (4) successive equal annual installments over the Optionee's period of continued service as a Board member, with
the first such installment to vest upon the Optionee's completion of one (1) year of Board service measured from the option grant date. With respect to annual share grants made prior to
January 26, 1999, such options shall vest, and the Corporation's repurchase right shall lapse, in two (2) successive equal annual installments over the Optionee's period of continued
service as a Board member, with the first such installment to vest upon the Optionee's completion of one (1) year of Board service measured from the option grant date. 

        E.    EFFECT
OF 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 in accordance with the laws of descent and distribution) shall have a twelve (12)-month period following the date of such cessation of Board service in which to
exercise each such option; provided, however, in no event shall the option be exercised later than the option term provided in 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 

12

 

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. 

        (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, the shares of Common Stock at the time subject to each outstanding option 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 fully exercisable for all of the shares of Common Stock at the time subject to such
option and may be exercised for all or any portion of those shares as fully-vested shares of Common Stock. 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, the shares of Common Stock at the time subject to each outstanding option 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 fully exercisable for all of the shares of Common Stock at the time subject to such option
and may be exercised for all or any portion of those shares as fully-vested shares of Common Stock. 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.    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
automatic option held by him or her. 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 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. 

        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. 

        E.    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.

        A.    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 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. Promissory notes may be authorized with or without security or collateral. In all events, the maximum credit available
to the Optionee or Participant may not exceed the sum of (i) the aggregate option exercise price or purchase price payable for the purchased 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.

Common Stock previously acquired by such holder (other than in connection with the option exercise or share vesting triggering the Taxes) with an aggregate Fair Market Value equal to the percentage of
the Taxes (not to exceed one hundred percent (100%)) designated by the holder.

Grant Program under the Plan became effective on the Underwriting Date. Options may be granted under the Discretionary Option Grant Program at any time on or after the Plan Effective Date. In
addition, the initial option grants under the Automatic Option Grant Program were made on the Underwriting Date to each Eligible Director at that time. 

        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 

14

 

options
outstanding under the Predecessor Plan as of such 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 of (i) December 31, 2005, (ii) the date on which all shares available for issuance under the Plan shall
have been issued pursuant to the exercise of the options or the issuance of shares (whether vested or unvested) under the Plan or (iii) the termination of all outstanding options in connection
with a Corporate Transaction. Upon such Plan termination, all outstanding stock options and unvested stock issuances shall continue to have force and effect in accordance with the provisions of the
documents evidencing such options 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 any rights and obligations with respect to options, stock appreciation rights 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. Notwithstanding the foregoing, the approval of
the holders of not less than a majority of the outstanding common stock of the Corporation entitled to vote shall be required to take the following actions: 

          (i)  amend
the Plan to materially modify the requirements for eligibility under the Plan; 

         (ii)  amend
the Plan to materially increase the number of shares of Common Stock which may be issued over the term of the Plan; or 

        (iii)  amend
the Plan to materially increase the benefits accruing to participants under the Plan as such benefits are currently set forth in the Plan. 

        B.    Options
to purchase shares of Common Stock may be granted under the Discretionary Option Grant Program 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 are 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 grants or issuances are made, then (i) any unexercised options granted on the basis of such excess shares shall terminate
and cease to be outstanding and (ii) the Corporation shall promptly refund to the Optionees and the Participants the exercise or purchase price paid for any excess shares issued under the Plan
and held in escrow, together with interest (at the applicable Short-Term Federal Rate) for the period the shares were held in escrow, and such shares shall thereupon be automatically
canceled 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.

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