EXHIBIT 10.44 ADVANCED FIBRE COMMUNICATIONS, INC.
1996 STOCK INCENTIVE PLAN 
  ARTICLE ONE GENERAL PROVISIONS I. PURPOSE OF THE PLAN This 1996 Stock Incentive Plan is intended to promote the interests of
Advanced Fibre Communications, Inc., a Delaware corporation, by providing

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 five separate equity 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 below-market 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 periodic
intervals to purchase shares of Common Stock, 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 below-market 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. III. ADMINISTRATION OF THE PLAN A. Prior to the Section 12 Registration Date, the Discretionary
Option Grant and Stock Issuance Programs shall be administered by the Board.
Beginning with the Section 12 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 and shall have
sole and exclusive authority to administer the Salary Investment Option Grant
Program with respect to all eligible individuals. 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 Employees eligible to receive
discretionary option grants or direct stock issuances under the Plan or any
other stock option, stock appreciation, stock bonus or other stock plan of the
Corporation (or any Parent or Subsidiary). C. Members of the Primary Committee or any Secondary Committee shall

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,
Salary Investment 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, Salary
Investment Option Grant and Stock Issuance Programs under its jurisdiction or
any option or stock issuance thereunder. 2.

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 and Director Fee
Option Grant Programs shall be self-executing in accordance with the terms of
that program, 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

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 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 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

##### 



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 after June 30, 1996, 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 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 maximum number of shares of Common Stock
initially reserved for issuance over the term of the Plan shall not exceed
7,175,676 shares. Such authorized share reserve is comprised of (i) the number
of shares which 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 the outstanding options to be incorporated into
the Plan and the additional shares which would otherwise be available for future
grant,(1) plus (ii) an additional increase of 1,000,000 shares authorized by
the Board but subject to stockholder approval prior to the Section 12
Registration Date. B. The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of each calendar
year during the term of the Plan, beginning with the 1997 calendar year, by an
amount equal to three percent (3.0%) of the shares of Common Stock outstanding
on the last trading day of the immediately preceding calendar year. No Incentive
Options may be granted on the basis of the additional shares of Common Stock
resulting from such annual increases. C. No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 400,000 shares of Common Stock in the aggregate per calendar year,
beginning with the 1996 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   (1)
    
    Estimated to be 6,175,676 shares of Common Stock as of June 30, 1996 4.

subsequent issuance under the Plan to the extent those options expire or
terminate for any reason prior to exercise in full. 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 issuance. Shares of Common Stock
underlying one or more stock appreciation rights exercised under the
Discretionary Option Grant Program 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 to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the 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 this 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 and (v) the number
and/or class of securities and price per share in effect under each outstanding
option incorporated into this Plan from the Predecessor Plan. 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. 5.

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. 1. The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the option grant date. 2. The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Six and the documents evidencing the option, be payable in one or more
of the forms specified below: (i) cash or check made payable to the Corporation, (ii) 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 (iii) 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. 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. 6.

##### 



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 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 exercisable in whole or in part by the
Optionee at the time of death 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 in accordance with the laws of descent and distribution. (iii) 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. (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 7.

##### 



period of time as the Plan Administrator shall deem appropriate, but in no
event beyond the expiration of the option term, and/or (ii) permit the option to be exercised, during the
applicable post-Service exercise period, not only with respect to the
number of vested shares of Common Stock for which such option is
exercisable at the time of the Optionees cessation of Service but
also with respect to one or more additional installments in which the
Optionee would have vested 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, a
Non-Statutory Option 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. 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 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. A. ELIGIBILITY. Incentive Options may only be granted to Employees. 8.

##### 



B. EXERCISE PRICE. The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date. C. DOLLAR LIMITATION. The aggregate Fair Market Value of the shares
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one calendar year shall
not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent
the Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted. D. 10% STOCKHOLDER. If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the 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, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof), (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
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.
The determination of option comparability under clause (i) above shall be made
by the Plan Administrator, and its determination shall be final, binding and
conclusive. 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: (i) those repurchase rights are to be assigned to the
successor corporation (or parent thereof) in connection with such 9.




---



##### 



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). 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. E. The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionees Service subsequently
terminates 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 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, and the shares subject to those
terminated repurchase rights shall accordingly vest in full. F. The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionees Service subsequently
terminates 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. 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, and the shares subject to those
terminated repurchase rights shall accordingly vest in full. 10.

##### 



G. 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
limitation is not exceeded. To the extent such dollar limitation is exceeded,
the accelerated portion of such option shall be exercisable as a Non-Statutory
Option under the Federal tax laws. H. The 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 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 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 11.

##### 



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, 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 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) Neither the approval of the Plan Administrator nor
the consent of the Board shall be required in connection with such
option surrender and cash distribution. (iv) The balance of the option (if any) shall remaining
outstanding and exercisable in accordance with the documents
evidencing such option. D. The shares of Common Stock underlying any stock appreciation
rights exercised under this Section V shall NOT be available for subsequent
issuance under the Plan. 12.

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 those 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). The Primary
Committee shall have complete discretion to determine whether or not to
approve the filed authorization in whole or in part. To the extent the
Primary Committee approves the authorization, the individual who filed that
authorization shall be granted an option under the Salary Investment Grant
Program on or before the last trading day in January of the calendar year for
which the salary reduction is to be in effect. All grants under the Salary
Investment Option Grant Program shall be at the sole discretion of the
Primary Committee. 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. 13.

##### 



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 DIVIDED BY (B x 66-2/3%), where X is the number of option shares, A is the dollar amount of the approved reduction in the
Optionees base salary for the calendar year, 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 in accordance with the laws of descent and distribution.
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 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 fully 14.




---



##### 



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. Each such outstanding option shall be
assumed by the successor corporation (or parent thereof) in the Corporate
Transaction 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. 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 become fully exercisable with respect to the total
number of shares of Common Stock at the time subject to such option and may be

The option shall remain so exercisable until the EARLIER or (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. C. The grant of options under the Salary Investment Option Grant

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 Salary Investment

ARTICLE FOUR STOCK ISSUANCE PROGRAM I. STOCK ISSUANCE TERMS Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below. A. PURCHASE PRICE. 1. The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than 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, namely: (i) the Service period to be completed by the
Participant or the performance objectives to be attained, (ii) the number of installments in which the shares are
to vest, 16.

##### 



(iii) the interval or intervals (if any) which are to
lapse between installments, and (iv) 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. 2. Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participants
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporations
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participants unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate. 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 17.




---



##### 



vesting of the Participants interest in the shares 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. II. CORPORATE TRANSACTION/CHANGE IN CONTROL A. All of the Corporations outstanding repurchase/cancellation
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/cancellation 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. 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 to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which those repurchase/cancellation rights
are assigned to the successor corporation (or parent thereof). C. 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 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. 18.

D. EXERCISE AND VESTING OF OPTIONS. Each option shall be
immediately exercisable for any or all of the option shares. However, any
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. Each grant shall vest, and
the Corporations repurchase right shall lapse, as follows: (i) one-third of
the option shares shall vest upon the Optionees completion of one (1) year of
Board service measured from the option grant date and (ii) the balance of the
option shares shall vest in a series of twenty-four (24) successive equal
monthly installments upon the Optionees completion of each additional month of
Board service over the twenty-four (24)-month period measured from the first
anniversary of such grant date. E. 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. (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. (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. 20.

II. SPECIAL CORPORATE EVENTS 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 of
his or her outstanding automatic option grants. 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 in connection
with such 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. 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. 21.

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

time exercisable. E. 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 the date of such cessation of Board service. 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 in accordance
with the laws of descent and distribution. Such right of exercise shall lapse,
and the option shall terminate, upon the EARLIER of (i) the expiration of the

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. Each such
outstanding option shall be assumed by the successor corporation (or parent
thereof) in the Corporate Transaction 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

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

ARTICLE SEVEN MISCELLANEOUS 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 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. II. TAX WITHHOLDING 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
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements. B. The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
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 Taxes incurred by such
holders 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 Taxes
(not to exceed one hundred percent (100%)) designated by the holder. STOCK DELIVERY: The election to deliver to the Corporation, at

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. III. EFFECTIVE DATE AND TERM OF THE PLAN A. The Plan shall become effective immediately upon the Plan
Effective Date. However, the Salary Investment 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 or Automatic Option
Grant Program at any time on or after the Plan Effective Date. 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 Section 12(g) Registration Date. All options
outstanding under the Predecessor Plan on the Section 12(g) Registration 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) June 30, 2006,
(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. Upon such plan
termination, all outstanding option grants and unvested stock issuances shall
thereafter continue to have force and effect in accordance with the provisions
of the documents evidencing such grants or issuances. 27.

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. 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 28.

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. 29.
