PROPOSAL NO. 2
AMENDMENT TO 1994 STOCK PLAN

GENERAL

The Company's 1994 Stock Plan was adopted by the Board of Directors and
approved by the Company's stockholders in January 1994 and provides for the
granting to employees (including officers and employee directors) of the Company
of incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code") and for the granting to employees
and consultants of the Company of nonstatutory stock options. A total of
2,322,0002,822,000 shares of Common Stock has been reserved for issuance under the 1994
Stock Plan and, as of March 27, 1998,April 12, 1999, a total of 36,904122,572 shares remained
available for future grant.

In 1993, Section 162(m) was added to the Code. Section 162(m) may
limit the Company's ability to deduct for United States federal income tax
purposes compensation in excess of $1,000,000 paid to the Company's Chief
Executive Officer and its four other highest paid executive officers in any
one fiscal year. Grants under the 1994 Stock Plan will not be subject to the
deduction limit if the stockholders approve the material terms of the 1994
Stock Plan, including the option grant limitations described below, for the
purposes of Section 162(m) of the Code.

PROPOSAL

In March 1998,April 1999, the Board of Directors adopted, subject to stockholder

reserved for issuance by an additional 500,000625,000 shares of Common Stock, for an
aggregate of 2,822,0003,447,000 shares reserved for issuance thereunder. This amendment

The Board of Directors is also seeking stockholder approval of the
material terms of the 1994 Stock Plan, including, but not limited to, the
share limitations for purposes of Section 162(m) of the Code only.

The Board of Directors believes that the approval of the amendment to
the 1994 Stock Plan and the material terms of the 1994 Stock Plan for
purposes of Section 162(m) of the Code is in the best interests of the Company and its
stockholders, as the availability of an adequate number of shares for issuance
under the 1994 Stock Plan and the ability to grant stock options are important
factors in attracting, motivating and retaining qualified personnel essential to
the success of the Company, as is the ability of the Company to deduct
compensation.

REQUIRED VOTE

The affirmative vote by the holders of a majority of the Common Stock
present in person or represented by proxy and entitled to vote on the subject
matter is required to approve (i) the amendment to the 1994 Stock Plan and (ii) the material terms of the 1994 Stock Plan for the purposes of

RECOMMENDATION: THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE
"FOR" THE AMENDMENT TO THE 1994 STOCK PLAN AND APPROVAL OF THE MATERIAL TERMS OF THE 1994 STOCK PLAN.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------

SUMMARY OF THE 1994 STOCK PLAN

The following summary of the 1994 Stock Plan is qualified in its
entirety by the specific language of the 1994 Stock Plan, a copy of which is
available to any stockholder upon written request to the Secretary of the
Company.

PURPOSE. The purposes of the 1994 Stock Plan are to attract and retain
the best available personnel for positions of substantial responsibility, to
provide additional incentive to employees and consultants of the Company and to
promote the success of the Company's business.

ADMINISTRATION. The 1994 Stock Plan may be administered by the Board of
Directors or a committee of the Board of Directors (the "Administrator"), which
committee is required to be constituted to comply with Section 16(b) of the
-6-

Securities Exchange Act of 1934, as amended (the "Exchange Act"), and applicable
laws. Subject to the other provisions of the 1994 Stock Plan, the Administrator
has the power to determine the employees and consultants to whom options may be
granted, the number of shares subject to the option and the exercisability
thereof. The Administrator also has the power to reprice options if the exercise
price of outstanding options exceeds the fair market value of the Company's
Common Stock.

ELIGIBILITY; LIMITATIONS. The 1994 Stock Plan provides that
nonstatutory stock options may be granted to employees and consultants.
Incentive stock options may be granted only to employees. An optionee who has
been granted an option may, if he or she is otherwise eligible, be granted
additional options.

-6-
Section 162(m) of the Code limits the deductibility of compensation
paid to certain executive officers of the Company. To maximize the Company's
deduction attributable to options granted to such persons, the 1994 Stock Plan
provides that no employee may be granted, in any fiscal year, options to
purchase more than 500,000 shares of Common Stock.

TERMS AND CONDITIONS OF OPTIONS. Each option granted under the 1994
Stock Plan is evidenced by a written stock option agreement between the optionee
and the Company and is subject to the following terms and conditions:

(a) Exercise Price.EXERCISE PRICE. The Administrator determines the exercise
price of options to purchase shares of Common Stock at the time the options are
granted. However, the exercise price of an incentive stock option must not be
less than 100% (110% if issued to any person possessing more than 10% of the
voting power of all classes of stock of the Company (a "10% Stockholder")) of
the fair market value of the Common Stock on the date the option is granted. For
so long as the Company's Common Stock is traded on the Nasdaq National Market,
the fair market value of a share of Common Stock will be the closing sales price
for such stock (or the closing bid if no sales were reported) on the last
trading day prior to the date of grant as quoted on such system.

(b) Exercise of the Option.EXERCISE OF THE OPTION. Each stock option agreement will
specify the term of the option and the date when the option is to become
exercisable. The terms of such vesting are to be determined by the
Administrator. Options granted under the 1994 Stock Plan to date generally
become exercisable over four years at a rate of one-fourth of the shares subject
to the options at the end of one year from the date of grant and 1/48th at the
end of each month thereafter and have a ten-year term. The maximum term of an
option granted to a 10% Stockholder is five years. An option is exercised by
giving written notice of exercise to the Company, specifying the number of full
shares of Common Stock to be purchased and by tendering full payment of the
purchase price to the Company.

(c) Form of Consideration.FORM OF CONSIDERATION. The consideration to be paid for
the shares of Common Stock issued upon exercise of an option shall be determined
by the Administrator and is set forth in the stock option agreement. Such form
of consideration may vary for each option, and may consist entirely of cash,
check, promissory note, other shares of the Company's Common Stock, any
combination thereof, or any other legally permissible form of consideration as
may be provided in the stock option agreement.

(d) Termination of Employment.TERMINATION OF EMPLOYMENT. In the event an optionee's
continuous status as an employee or consultant terminates for any reason (other
than upon the optionee's death or disability), the optionee may exercise his or
her option within such period of time as is specified in such optionee's stock
option agreement but only to the extent that the optionee was entitled to
exercise the option at the date of such termination (but in no event later than
the expiration of the term of such option as set forth in the stock option
agreement). Options granted under the 1994 Stock Plan to date have generally
provided that optionees may exercise their options within sixty days from the
date of termination of employment (other than for death or disability).

(e) Disability.DISABILITY. In the event an optionee's continuous status
as an employee or consultant terminates as a result of permanent and total
disability (as defined in Section 22(e)(3) of the Code), the optionee may
exercise his or her option, but only within twelve months from the date of such
termination, and only to the extent that the optionee was entitled to exercise
it at the date of such termination (but in no event later than the expiration of
the term of such option as set forth in the stock option agreement).

(f) Death.DEATH. In the event of an optionee's death, the optionee's
estate or a person who acquired the right to exercise the deceased optionee's
option by bequest or inheritance may exercise the option, but only within twelve
months

-7-
following the date of death, and only to the extent that the optionee was
entitled to exercise it at the date of death (but in no event later than the
expiration of the term of such option as set forth in the stock option
agreement).

(g) Term of Options.TERM OF OPTIONS. The term of each option is the term
stated in the stock option agreement; provided, however, that the term may not
exceed ten years from the date of grant. In the case of an incentive stock
option granted to a 10% Stockholder, the term may not exceed five years from the
date of grant. No option may be exercised by any person after the expiration of
its term.

-7-
(h) Nontransferability of Options.NONTRANSFERABILITY OF OPTIONs. An option is
nontransferable by the optionee, other than by will or the laws of descent and
distribution, and is exercisable during the optionee's lifetime only by the
optionee. In the event of the optionee's death, options may be exercised by a
person who acquires the right to exercise the option by bequest or inheritance.

(i) Value Limitation.VALUE LIMITATION. If the aggregate fair market value (as
determined on date of grant) of all shares of Common Stock subject to an
optionee's incentive stock option which are exercisable for the first time
during any calendar year exceeds $100,000, the excess options shall be treated
as nonstatutory options.

(j) Other Provisions.OTHER PROVISIONS. The stock option agreement may contain
such other terms, provisions and conditions not inconsistent with the 1994 Stock
Plan as may be determined by the Administrator.

ADJUSTMENT UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS. In
the event of changes in the outstanding Common Stock of the Company by reason of
any stock splits, reverse stock splits, stock dividends, combinations,
reclassifications or other similar change in the capital structure of the
Company, an appropriate adjustment shall be made by the Administrator in the
following: (i) the number of shares of Common Stock subject to the 1994 Stock
Plan, (ii) the number and class of shares of stock subject to any option
outstanding under the 1994 Stock Plan, and (iii) and the exercise price of any such
outstanding option. The determination of the Administrator as to which
adjustments made shall be conclusive. In the event of a proposed dissolution or
liquidation of the Company, the Board will notify the holders of options as soon
as practicable prior to such action, and all outstanding options will terminate
immediately prior to the consummation of such proposed action. Notwithstanding
the above, in the event of a merger of the Company with or into another
corporation or the sale of substantially all of the assets of the Company, the
1994 Stock Plan requires that each outstanding option be assumed or an
equivalent option be substituted by the successor corporation; provided,
however, if such successor or purchaser refuses to assume or substitute the then
outstanding options, the 1994 Stock Plan provides for the full acceleration of
the exercisability of all outstanding options for a period of ten days from the
date of notice of acceleration to the holder and all options will terminate upon
the expiration of such period.

AMENDMENT AND TERMINATION OF THE 1994 STOCK PLAN. The Board may at any
time amend, alter, suspend or terminate the 1994 Stock Plan. The Company shall
obtain stockholder approval of any amendment to the 1994 Stock Plan in such a
manner and to such a degree as is necessary and desirable to comply with Rule
16b-3 under the Exchange Act and Sections 162(m) and 422 of the Code (or any
other applicable law or regulation, including the requirements of any exchange
or quotation system on which the Common Stock is traded). Any amendment or
termination of the 1994 Stock Plan shall not affect options already granted and
such options shall remain in full force and effect as if the 1994 Stock Plan had
not been amended or terminated, unless mutually agreed otherwise between the
optionee and the Company, which agreement must be in writing and signed by the
optionee and the Company. In any event, the 1994 Stock Plan shall terminate in
May 2004. Any options outstanding under the 1994 Stock Plan at the time of its
termination shall remain outstanding until they expire by their terms.

FEDERAL INCOME TAX CONSEQUENCES

INCENTIVE STOCK OPTIONS. An optionee who is granted an incentive stock
option does not recognize taxable income at the time the option is granted or
upon its exercise, although the exercise may subject the optionee to the
alternative minimum tax. Upon a disposition of the shares more than two years
after grant of the option and one year after exercise of the option, any gain or
loss is treated as long-term capital gain or loss. If these holding periods are
not satisfied, the optionee recognizes ordinary income at the time of
disposition equal to the difference between the exercise price and the lower of
(i) the fair market value of the shares at the date of the option exercise or
(ii) the sale price of the shares. Any gain or loss recognized on such a
premature disposition of the shares in excess of the amount treated as ordinary
income is treated as long-term or short-term capital gain or loss, depending on
the holding period. Long-term capital gains are grouped and netted by -8-
holding
periods. Net capital gains on assets held for more than twelve months and up to eighteen months isare
currently taxed at a maximum federal rate of 28%. Net capital gains on assets held for more than 18 months is capped at 20%. Capital losses are allowed in
full against capital gains and up to $3,000 against other income. A different
rule for measuring ordinary income upon such a premature disposition may apply
if the optionee is also an officer, director, or 10% Stockholder of the Company.
The Company is entitled to a deduction in the same amount as the ordinary income
recognized by the optionee.

-8-

NONSTATUTORY STOCK OPTIONS. An optionee does not recognize any taxable
income at the time he or she is granted a nonstatutory stock option. Upon
exercise, the optionee recognizes taxable income generally measured by the
excess of the then fair market value of the shares over the exercise price. Any
taxable income recognized in connection with an option exercise by an employee
of the Company is subject to tax withholding by the Company. The Company is
entitled to a deduction in the same amount as the ordinary income recognized by
the optionee. Upon a disposition of such shares by the optionee, any difference
between the sale price and the optionee's exercise price, to the extent not
recognized as taxable income as provided above, is treated as long-term or
short-term capital gain or loss, depending on the holding period. Net capital
gains on assets held for more than twelve months and up to eighteen months isare currently taxed at a
maximum federal rate of
28%. Net capital gains on assets held for more than 18 months is capped at 20%. Capital losses are allowed in full against capital
gains and up to $3,000 against other income.

The purchaser may accelerate to the date of purchase his or her
recognition of ordinary income, if any, and the beginning of any capital gain
holding period by timely filing an election pursuant to Section 83(b) of the
Code. In such event, the ordinary income recognized, if any, is measured as the
difference between the purchase price and the fair market value of the stock on
the date of purchase, and the capital gain holding period commences on such
date. The ordinary income recognized by a purchaser who is an employee will be
subject to tax withholding by the Company. Different rules may apply if the
purchaser is also an officer, director, or 10% Stockholder of the Company.

THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME
TAXATION UPON OPTIONEES AND THE COMPANY WITH RESPECT TO THE GRANT AND EXERCISE
OF OPTIONS UNDER THE 1994 STOCK PLAN. IT DOES NOT PURPORT TO BE COMPLETE, AND
DOES NOT DISCUSS THE TAX CONSEQUENCES OF THE EMPLOYEE'S OR CONSULTANT'S DEATH OR
THE PROVISIONS OF THE INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN
COUNTRY IN WHICH THE EMPLOYEE OR CONSULTANT MAY RESIDE.

market value of the Common Stock on the first day of each 24-month offering
period or the last day of the applicable six-month purchase period. The Company

lower of the fair market value of the Common Stock on the first day of each
24-month offering period and the last day of the applicable six-month purchase
period. To the extent the fair market value of the Common Stock on any exercise
date in an offering period is lower than the fair market value of the Common
Stock on the first day of the offering period, then all participants in such
offering period will be automatically withdrawn from such offering period
immediately after the exercise of their options on such exercise date and
automatically re-enrolled in the immediately following offering period as of the
first day thereof.

the Company, which agreement must be in writing and signed by the participant
and the Company. In any event, the 1996 Employee Stock Purchase Plan shall

FEDERAL INCOME TAX CONSEQUENCES

No income will be taxable to a participant until the shares purchased
under the 1996 Employee Stock Purchase Plan are sold or otherwise disposed of.
Upon sale or other disposition of the shares, the participant will generally be
subject to tax and the amount of the tax will depend upon the holding period. If
the shares are sold or otherwise disposed of more than two (2) years from the
first day of the offering period or more than one (1) year from the date of
transfer of the stock to the participant (the "Statutory Holding Periods"), then
the participant will recognize ordinary income measured as the lesser of (i) the
excess of the fair market value of the shares at the time of such sale or
disposition over the purchase price, or (ii) an amount equal to 15% of the fair
market value of the shares as of the first day of the offering period. Any
additional gain will be treated as long-term capital gain. Net capital gains on
assets held for more than twelve months and up to eighteen months are currently taxed at a maximum federal
rate of 28%. Net capital gains on assets held for more than 18 months
are capped at 20%. Capital losses are allowed in full against capital gains and up to
$3,000 against other income. If the shares are sold or otherwise disposed of
before the expiration of the Statutory Holding Periods, the participant will
recognize ordinary income generally measured as the excess of the fair market
value of the shares on the date the shares are purchased over the purchase
price. Any additional gain or loss on such sale or disposition will be long-term
or short-term capital gain or loss, depending on the holding periods. The
Company is not entitled to a deduction for amounts taxed as ordinary income or
capital gain to a participant except to the extent of ordinary income is
recognized by participants upon a sale or disposition of shares prior to the
expiration of the Statutory Holding Periods described above.

THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME
TAXATION UPON THE PARTICIPANT AND THE COMPANY WITH RESPECT TO THE SHARES
PURCHASED UNDER THE PURCHASE PLAN. REFERENCE SHOULD BE MADE TO THE APPLICABLE
PROVISIONS OF THE CODE. IN ADDITION, THE SUMMARY DOES NOT PURPORT TO BE
COMPLETE, AND DOES NOT DISCUSS THE TAX CONSEQUENCES OF A PARTICIPANT'STHE EMPLOYEE'S OR
CONSULTANT'S DEATH OR THE PROVISIONS OF THE INCOME TAX LAWS OF ANY MUNICIPALITY,
STATE OR FOREIGN COUNTRY IN WHICH THE PARTICIPANTEMPLOYEE OR CONSULTANT MAY RESIDE.

executive officer of the Company, for the purchase of a primary residence
pursuant to a promissory note that bore interest at the rate of 5% per year.

a registered class of the Company's equity securities to file reports of
ownership and changes in ownership with the Securities and Exchange Commission
("SEC"). Executive officers, directors and greater than 10% stockholders are
required by SEC rules to furnish the Company with copies of all forms they file.
Based solely on its review of the copies of such forms received by the Company
and written representations from certain reporting persons, the Company believes
that, during 1997,1998, all Section 16(a) filing requirements applicable to its
executive officers, directors and 10% stockholders were satisfied, except that the Form 3 for Richard Davenport and
the Form 4's for DCL Technologies Ltd. for September 1997 and November 1997

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee was formed in August 1994 and is currently

other company's board of directors or compensation committee.

CHANGES IN ACCOUNTANTS

principal independent accountants for the Company and its subsidiaries,
replacing KPMG Peat Marwick LLP ("KPMG"), which was dismissed in January
1996. The change was approved by the Audit Committee of the Company's Board
of Directors. In connection with the audits of the year ended December 31,
1995 and through the interim period ended February 8, 1996, there were no
disagreements with KPMG on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedures, which
disagreements, if not resolved to KPMG's satisfaction, would have caused them
to make reference to the matter in their report. The audit reports of KPMG
on the consolidated financial statements of the Company as of and for the
year ended December 31, 1994 did not contain any adverse opinion or
disclaimer of opinion, nor were they qualified or modified as to uncertainty
or audit scope. The audit report for the year ended December 31, 1994 was
modified to include a discussion on the restatement of the Company's 1993
financial statements for the timing of when certain expenses were recognized
in the financial statements. During the audit period ended December 31,
1994, and through the interim period ended January 31, 1996 there have been
no reportable events.

During the two fiscal years ended December 31, 1996, and through
the interim period ended February 8, 1996, the Company had not consulted with
Coopers & Lybrand L.L.P. on items which concerned the subject matter of a
disagreement or reportable event with the former auditor.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

The Compensation Committee of the Board of Directors (the "Committee")
was established in August 1994 and is responsible for reviewing the compensation
and benefits for the Company's executive officers, as well as supervising and
making recommendations to the Board on compensation matters generally. The
Committee also administers the Company's stock plans.

COMPENSATION PHILOSOPHY AND POLICY

The policy of the Committee is to attract and retain executive officers
and employees through the payment of competitive base salaries and to encourage
and reward performance through bonuses and stock ownership. The objectives of
the Committee are to:

- attract, retain and motivate highly qualified executive
officers and employees who contribute to the long-term success
of the Company;

- align the compensation of executive officers with business
objectives and performance; and

- align incentives for executive officers with the interests of
stockholders in maximizing value.

The Company has taken the necessary steps to conform its compensation
practices to comply with the $1 million compensation deduction cap under Section
162(m) of the Internal Revenue Code, as amended.

ELEMENTS OF COMPENSATION

Compensation for executive officers includes both cash and equity
elements.

Cash compensation consists of (i) base salary which is determined on
the basis of the level of responsibility, expertise and experience of the
executive officer, taking into account competitive conditions in the industry
and (ii) cash bonuses up to an established percentage of base salary, subject to
meeting all or a portion of targeted objectives.

Ownership of the Company's Common Stock is a key element of executive
compensation. Executive officers and other employees of the Company are eligible
to participate in the 1994 Stock Plan (the "Option Plan") and the 1996 Employee
Stock Purchase Plan (the "Purchase Plan"). The Option Plan permits the Board of
Directors or the Committee to grant stock options to employees on such terms as
the Board or the Committee may determine. The Committee has the sole authority
to grant stock options to executive officers of the Company and is currently
administering stock option grants to all employees. In determining the size of a
stock option grant to a new executive officer or other employee, the Committee
takes into account equity participation by comparable employees within the
Company, external competitive circumstances and other relevant factors.
Additional options may be granted to current executive officers and employees to
reward exceptional performance or to provide additional unvested equity
incentives. These options typically vest over a four-year period and thus
require the employee's continuing service to the Company. The Purchase Plan
permits employees to acquire Common Stock of the Company through payroll
deductions and promotes broad-based equity participation throughout the Company.
The Committee believes that such stock plans align the interests of the
employees with the long-term interests of the stockholders.

The Company also maintains a 401(k) Plan to provide retirement benefits
through tax deferred salary deductions for all its employees. In 1997,1998, the
Company contributed to the 401(k) Plan by partially matching employees'
contribution at a one-to-four ratio; provided, however, that the Company's
matching contribution for any employee could not exceed 1.5% of such employee's
salary.

(a) PLAN PROCEDURE.

(i) ADMINISTRATION WITH RESPECT TO DIRECTORS AND
OFFICERS. With respect to grants of Options to Employees who are also officers
or directors of the Company, the Plan shall be administered by (A) the Board if
the Board may administer the Plan in compliance with

-3-A-3

Rule 16b-3 promulgated under the Exchange Act or any successor thereto
("Rule 16b-3") with respect to a plan intended to qualify thereunder as a
discretionary plan, or (B) a Committee designated by the Board to administer the
Plan, which Committee shall be constituted in such a manner as to permit the
Plan to comply with Rule 16b-3 with respect to a plan intended to qualify
thereunder as a discretionary plan. Once appointed, such Committee shall
continue to serve in its designated capacity until otherwise directed by the
Board. From time to time the Board may increase the size of the Committee and
appoint additional members thereof, remove members (with or without cause) and
appoint new members in substitution therefor, fill vacancies, however caused,
and remove all members of the Committee and thereafter directly administer the
Plan, all to the extent permitted by Rule 16b-3 with respect to a plan intended
to qualify thereunder as a discretionary plan.

(ii) MULTIPLE ADMINISTRATIVE BODIES. If permitted by
Rule 16b-3, the Plan may be administered by different bodies with respect to
directors, non-director officers and Employees who are neither directors nor
officers.

(iii) ADMINISTRATION WITH RESPECT TO CONSULTANTS AND
OTHER EMPLOYEES. With respect to grants of Options to Employees or Consultants
who are neither directors nor officers of the Company, the Plan shall be
administered by (A) the Board or (B) a Committee designated by the Board, which
Committee shall be constituted in such a manner as to satisfy the legal
requirements relating to the administration of incentive stock option plans, if
any, of applicable state corporate and securities laws, of the Code, and of any
applicable stock exchange (including Nasdaq) (the "Applicable Laws"). Once
appointed, such Committee shall continue to serve in its designated capacity
until otherwise directed by the Board. From time to time the Board may increase
the size of the Committee and appoint additional members thereof, remove members
(with or without cause) and appoint new members in substitution therefor, fill
vacancies, however caused, and remove all members of the Committee and
thereafter directly administer the Plan, all to the extent permitted by the
Applicable Laws.

(b) POWERS OF THE ADMINISTRATOR. Subject to the provisions
of the Plan and, in the case of a Committee, the specific duties delegated by
the Board to such Committee, and subject to the approval of any relevant
authorities, including the approval, if required, of any stock exchange upon
which the Common Stock is listed, the Administrator shall have the authority, in
its discretion:

(i) to determine the Fair Market Value of the Common
Stock, in accordance with Section 2(l) of the Plan;

(ii) to select the Consultants and Employees to whom
Options may from time to time be granted hereunder;

-4-A-4

(iii) to determine whether and to what extent Options or
any combination thereof are granted hereunder;

(iv) to determine the number of shares of Common Stock
to be covered by each such award granted hereunder;

(v) to approve forms of agreements for use under the
Plan, which forms may differ with respect to individual Optionees;

(vi) to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder,
including the terms of any right of first refusal of the Company to purchase
Shares granted pursuant to the Plan and the terms of any repurchase option of
the Company with respect to unvested Shares;

(vii) with respect to any Option, to determine whether
and under what circumstances an Option may be settled in cash under
subsection 9(f) instead of Common Stock;

(viii) to reduce the exercise price of the Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was
granted; and

(ix) to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan.

(c) EFFECT OF ADMINISTRATOR'S DECISION. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.

5. ELIGIBILITY.

(a) Nonstatutory Stock Options may be granted to Employees
and Consultants. Incentive Stock Options may be granted only to Employees. An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

(b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary, including Options granted in substitution of options granted under
the TSSI Plan) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.

-5-A-5

(c) For purposes of Section 5(b), Incentive Stock Options
shall be taken into account in the order in which they were granted, and the
Fair Market Value of the Shares shall be determined as of the time the Option
with respect to such Shares is granted.

(d) The Plan shall not confer upon any Optionee any right
with respect to continuation of employment relationship with the Company, nor
shall it interfere in any way with his or her right or the Company's right to
terminate his or her employment relationship at any time, with or without cause.

(e) The following limitations shall apply to grants of
Options to Employees:

(i) No Employee shall be granted, in any fiscal year
of the Company, Options to purchase more than 500,000 Shares.

(ii) The foregoing limitation shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11(a).

(iii) If an Option is canceled in the same fiscal year
of the Company in which it was granted (other than in connection with a
transaction described in Section 11), the canceled Option shall be counted
against the limit set forth in Section 5(e)(i). For this purpose, if the
exercise price of an Option is reduced, the transaction shall be treated as a
cancellation of the Option and the grant of a new Option.

6. TERM OF PLAN. The Plan shall become effective upon the earlier
to occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company, as described in Section 17 of the Plan. It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 13 of the Plan.

7. TERM OF OPTION. The term of each Option shall be the term stated
in the Option Agreement; provided, however, that the term shall be no more than
ten (10) years from the date of grant thereof. However, in the case of an
Incentive Stock Option granted to an Optionee who, at the time the Option is
granted, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the term of
the Option shall be five (5) years from the date of grant thereof or such
shorter term as may be provided in the Option Agreement.

-6-A-6

8. OPTION EXERCISE PRICE AND CONSIDERATION.

(a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Committee, but shall be subject to the following:

(i) In the case of an Incentive Stock Option

(A) granted to an Employee who, at the time of
the grant of such Incentive Stock Option, owns stock representing more than ten
percent (10%) of the voting power of all classes of stock of the Company or any
Parent or Subsidiary, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant.

(B) granted to any other Employee, the per
Share exercise price shall be no less than 100% of the Fair Market Value per
Share on the date of grant.

(ii) In the case of a Nonstatutory Stock Option, the
per Share exercise price shall be determined by the Committee.

(b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and, in the case of a Prior TSSI ISO may
consist entirely of (1) cash, (2) check, or (3) other Shares which (x) in the
case of Shares acquired upon exercise of an Option, have been owned by the
Optionee for more than six months on the date of surrender, and (y) have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which said Option shall be exercised. In the case of all other
Options, the consideration may consist entirely of (1) cash, (2) check,
(3) promissory note, (4) other Shares which (x) in the case of Shares acquired
upon exercise of an Option, have been owned by the Optionee for more than six
months on the date of surrender, and (y) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised, (5) delivery of a properly executed exercise notice
together with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price, or
(6) any combination of the foregoing methods of payment. In making its
determination as to the type of consideration to accept, the Board shall
consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

-7-A-7

9. EXERCISE OF OPTION.

(a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any
Nonstatutory Option and, subject to the $100,000 limitation of Section 5(b) on
the exercisability of Incentive Stock Options in any one year, any Incentive
Stock Option granted hereunder shall be exercisable under such conditions as
determined by the Board, including performance criteria with respect to the
Company and/or the Optionee, and as shall be permissible under the terms of the
Plan.

An Option may not be exercised for a fraction of a Share.

An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in accordance with the
terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under Section 8(b) of the
Plan. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the Option. No
adjustment shall be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

(b) TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP. In
the event of termination of an Optionee's Continuous Status as an Employee or
Consultant with the Company, such Optionee may within sixty (60) days after the
date of such termination (but in no event later than the expiration date of the
term of such Option as set forth in the Option Agreement), exercise his or her
Option to the extent that Optionee was entitled to exercise it at the date of
such termination. To the extent that Optionee was not entitled to exercise the
Option at the date of such termination, or if Optionee does not exercise such
Option to the extent so entitled within the time specified herein, the Option
shall terminate. Notwithstanding the above provisions of this Section 9(b), in
the event of an Optionee's change of status from Consultant to Employee, an
Optionee's Nonstatutory Stock Option shall not automatically terminate solely as
a result of such change of status. In addition, in the case of an Option other
than a Prior TSSI ISO, in the event of an Optionee's change of status from
Employee to Consultant, an Employee's Incentive Stock Option shall not
automatically terminate but shall cease to be treated as an Incentive Stock
Option and shall be treated for tax purposes as a Nonstatutory Stock Option on
the ninety-first (91st) day following such change of status.

-8-A-8

(c) DISABILITY OF OPTIONEE. In the event that an Optionee's
Continuous Status as an Employee or Consultant terminates as a result of the
Optionee's Disability, the Optionee may exercise his or her Option at any time
within twelve (12) months from the date of such termination, but only to the
extent that the Optionee was entitled to exercise it at the date of such
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement). If, at the date of termination,
the Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

(d) DEATH OF OPTIONEE. In the event of the death of an
Optionee, the Option may be exercised at any time within twelve (12) months
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent that the Optionee was entitled to
exercise the Option at the date of death. If, at the time of death, the
Optionee was not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall immediately revert to
the Plan. If, after death, the Optionee's estate or a person who acquired the
right to exercise the Option by bequest or inheritance does not exercise the
Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

(e) RULE 16b-3. Options granted to persons subject to
Section 16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain
such additional conditions or restrictions as may be required thereunder to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

(f) BUYOUT PROVISIONS. The Administrator may at any time
offer to buy out for a payment in cash or Shares, an Option previously granted,
based on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

10. NON-TRANSFERABILITY OF OPTIONS. Options may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent or distribution and may be exercised,
during the lifetime of the Optionee, only by the Optionee.

11. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

(a) CHANGES IN CAPITALIZATION. Subject to any required
action by the stockholders of the Company, the number of shares of Common Stock
covered by each outstanding Option, and the number of shares of Common Stock
which have been authorized for

-9-A-9

issuance under the Plan but as to which no Options have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option, as well as the price per share of Common Stock covered by each such
outstanding Option, shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
shares of Common Stock effected without receipt of consideration by the Company;
provided, however, that conversion of any convertible securities of the Company
shall not be deemed to have been "effected without receipt of consideration."
Such adjustment shall be made by the Board, whose determination in that respect
shall be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option.

(b) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Optionee shall have the right to exercise his or her Option
until ten (10) days prior to such transaction as to all of the Optioned Stock
covered thereby. In addition, any Company repurchase option applicable to
Shares shall lapse as to all such Shares, provided such transaction takes place
at the time and in the manner contemplated. To the extent it has not been
previously exercised, the Option will terminate immediately prior to the
consummation of such proposed action.

(c) MERGER OR ASSET SALE. In the event of a merger of the
Company with or into another corporation, or the sale of substantially all of
the assets of the Company:

(i) OPTIONS. Each Option shall be assumed or an
equivalent Option shall be substituted by such successor corporation (including
as a "Successor" any purchaser of substantially all of the assets of the
Company) or a parent or subsidiary of such successor corporation. In the event
that the successor corporation or a parent or subsidiary of such successor
corporation does not agree to assume the Option or to substitute an equivalent
option, the Administrator shall, as soon as practicable prior to the effective
date of such transaction, provide for the Optionee to have the right to exercise
the Option as to all or a portion of the Optioned Stock, including Shares that
would not otherwise be exercisable. In such event the Administrator shall
notify the Optionee as soon as practicable prior to the effective date of such
transaction that the Option shall be fully exercisable for a period of ten (10)
days from the date of such notice, and the Option shall terminate upon the
expiration of such period. For the purposes of this paragraph, the Option shall
be considered assumed if, following the merger, the Option confers the right to
purchase, for each Share of Optioned Stock subject to the Option immediately
prior to the merger, the consideration (whether stock, cash, or other securities
or property) received in the merger by holders of Common Stock for each Share
held on the effective date of the transaction (and if holders were offered a
choice of consideration, the type of consideration -10-

chosen by the holders of

A-10

a majority of the outstanding Shares); provided, however, that if such
consideration received in the merger was not solely common stock of the
successor corporation or its Parent, the Administrator may, with the consent of
the successor corporation, provide for the consideration to be received upon the
exercise of the Option, for each Share of Optioned Stock subject to the Option,
to be solely common stock of the successor corporation or its Parent equal in
fair market value to the per share consideration received by holders of Common
Stock in the merger.

(ii) SHARES SUBJECT TO REPURCHASE OPTION. Any Shares
subject to a repurchase option of the Company shall be exchanged for the
consideration (whether stock, cash, or other securities or property) received in
the merger or asset sale by the holders of Common Stock for each Share held on
the effective date of the transaction, as described in the preceding paragraph.
If the Optionee receives shares of stock of the successor corporation or a
parent or subsidiary of such successor corporation in exchange for Shares
subject to a repurchase option, such exchanged shares shall continue to be
subject to the repurchase option as provided in the Restricted Stock Purchase
Agreement.

12. TIME OF GRANTING OPTIONS. The date of grant of an Option shall,
for all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board. Notice
of the determination shall be given to each Employee or Consultant to whom an
Option is so granted within a reasonable time after the date of such grant.

13. AMENDMENT AND TERMINATION OF THE PLAN.

(a) AMENDMENT AND TERMINATION. The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422 of the Code (or any other applicable law or
regulation, including the requirements of Nasdaq or an established stock
exchange), the Company shall obtain stockholder approval of any Plan amendment
in such a manner and to such a degree as required.

comply with all relevant provisions of law, including, without

A-11

limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules

obtained.

5. PARTICIPATION.

-3-B-3

(a) An eligible Employee may become a participant in the Plan
by completing a subscription agreement authorizing payroll deductions in the
form of Exhibit A to this Plan and filing it with the Company's payroll office
prior to the applicable Enrollment Date.

(b) Payroll deductions for a participant shall commence on
the first payroll following the Enrollment Date and shall end on the last
payroll in the Offering Period to which such authorization is applicable, unless
sooner terminated by the participant as provided in Section 10 hereof.

6. PAYROLL DEDUCTIONS.

(a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period.

(b) All payroll deductions made for a participant shall be
credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

(c) A participant may discontinue his or her participation in
the Plan as provided in Section 10 hereof, or may increase or decrease the rate
of his or her payroll deductions during the Offering Period by completing or
filing with the Company a new subscription agreement authorizing a change in
payroll deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

(d) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a
participant's payroll deductions may be decreased to zero percent (0%) at such
time during any Purchase Period which is scheduled to end during the current
calendar year (the "Current Purchase Period") that the aggregate of all payroll
deductions which were previously used to purchase stock under the Plan in a
prior Purchase Period which ended during that calendar year plus all payroll
deductions accumulated with respect to the Current Purchase Period equal
$21,250. Payroll deductions shall recommence at the rate provided in such
participant's subscription agreement at the beginning of the first Purchase
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

-4-B-4

(e) At the time the option is exercised, in whole or in part,
or at the time some or all of the Company's Common Stock issued under the Plan
is disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

7. GRANT OF OPTION. On the Enrollment Date of each Offering Period,
each eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than a
number of shares determined by dividing $12,500 by the Fair Market Value of a
share of the Company's Common Stock on the Enrollment Date, and provided further
that such purchase shall be subject to the limitations set forth in
Sections 3(b) and 12 hereof. Exercise of the option shall occur as provided in
Section 8 hereof, unless the participant has withdrawn pursuant to Section 10
hereof. The option shall expire on the last day of the Offering Period.

8. EXERCISE OF OPTION. Unless a participant withdraws from the Plan
as provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to
purchase shares hereunder is exercisable only by him or her.

9. DELIVERY. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

10. WITHDRAWAL; TERMINATION OF EMPLOYMENT.

(a) A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any

-5-B-5

time by giving written notice to the Company in the form of Exhibit B to this
Plan. All of the participant's payroll deductions credited to his or her
account shall be paid to such participant promptly after receipt of notice of
withdrawal and such participant's option for the Offering Period shall be
automatically terminated, and no further payroll deductions for the purchase of
shares shall be made for such Offering Period. If a participant withdraws from
an Offering Period, payroll deductions shall not resume at the beginning of the
succeeding Offering Period unless the participant delivers to the Company a new
subscription agreement.

(b) Upon a participant's ceasing to be an Employee (as
defined in Section 2(g) hereof), for any reason, he or she shall be deemed to
have elected to withdraw from the Plan and the payroll deductions credited to
such participant's account during the Offering Period but not yet used to
exercise the option shall be returned to such participant or, in the case of his
or her death, to the person or persons entitled thereto under Section 14 hereof,
and such participant's option shall be automatically terminated. The preceding
sentence notwithstanding, a participant who receives payment in lieu of notice
of termination of employment shall be treated as continuing to be an Employee
for the participant's customary number of hours per week of employment during
the period in which the participant is subject to such payment in lieu of
notice.

(c) A participant's withdrawal from an Offering Period shall
not have any effect upon his or her eligibility to participate in any similar
plan which may hereafter be adopted by the Company or in succeeding Offering
Periods which commence after the termination of the Offering Period from which
the participant withdraws.

11. INTEREST. No interest shall accrue on the payroll deductions of
a participant in the Plan.

12. STOCK.

(a) The maximum number of shares of the Company's Common
Stock which shall be made available for sale under the Plan shall be 150,000535,000
shares, subject to adjustment upon changes in capitalization of the Company as
provided in Section 18 hereof. If, on a given Exercise Date, the number of
shares with respect to which options are to be exercised exceeds the number of
shares then available under the Plan, the Company shall make a pro rata
allocation of the shares remaining available for purchase in as uniform a manner
as shall be practicable and as it shall determine to be equitable.

(b) The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

(c) Shares to be delivered to a participant under the Plan
shall be registered in the name of the participant or in the name of the
participant and his or her spouse.

-6-B-6

13. ADMINISTRATION.

(a) ADMINISTRATIVE BODY. The Plan shall be administered by the
Board or a committee of members of the Board appointed by the Board. The Board
or its committee shall have full and exclusive discretionary authority to
construe, interpret and apply the terms of the Plan, to determine eligibility
and to adjudicate all disputed claims filed under the Plan. Every finding,
decision and determination made by the Board or its committee shall, to the full
extent permitted by law, be final and binding upon all parties.

(b) RULE 16b-3 LIMITATIONS. Notwithstanding the provisions
of Subsection (a) of this Section 13, in the event that Rule 16b-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
any successor provision ("Rule 16b-3") provides specific requirements for the
administrators of plans of this type, the Plan shall be administered only by
such a body and in such a manner as shall comply with the applicable
requirements of Rule 16b-3. Unless permitted by Rule 16b-3, no discretion
concerning decisions regarding the Plan shall be afforded to any committee or
person that is not "disinterested" as that term is used in Rule 16b-3.

14. DESIGNATION OF BENEFICIARY.

(a) A participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to an Exercise Date on which the option is exercised but prior to
delivery to such participant of such shares and cash. In addition, a
participant may file a written designation of a beneficiary who is to receive
any cash from the participant's account under the Plan in the event of such
participant's death prior to exercise of the option. If a participant is
married and the designated beneficiary is not the spouse, spousal consent shall
be required for such designation to be effective.

(b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

15. TRANSFERABILITY. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant. Any such
attempt

-7-B-7

at assignment, transfer, pledge or other disposition shall be without effect,
except that the Company may treat such act as an election to withdraw funds from
an Offering Period in accordance with Section 10 hereof.

16. USE OF FUNDS. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

17. REPORTS. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

18. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION,
LIQUIDATION, MERGER OR ASSET SALE.

(a) CHANGES IN CAPITALIZATION. Subject to any required
action by the stockholders of the Company, the Reserves, as well as the price
per share and the number of shares of Common Stock covered by each option under
the Plan which has not yet been exercised, shall be proportionately adjusted for
any increase or decrease in the number of issued shares of Common Stock
resulting from a stock split, reverse stock split, stock dividend, combination
or reclassification of the Common Stock, or any other increase or decrease in
the number of shares of Common Stock effected without receipt of consideration
by the Company; provided, however, that conversion of any convertible securities
of the Company shall not be deemed to have been "effected without receipt of
consideration". Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an option.

(b) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Offering Periods shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

(c) MERGER OR ASSET SALE. In the event of a proposed sale of
all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, any Purchase Periods then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date") and
any Offering Periods then in progress shall end on the New Exercise Date. The
New Exercise Date shall be before the date of the Company's proposed sale or
merger. The Board shall notify each participant in writing, at least ten (10)
business days prior to the New Exercise Date, that the Exercise Date for the
participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New

-8-B-8

Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

19. AMENDMENT OR TERMINATION.

(a) The Board of Directors of the Company may at any time and
for any reason terminate or amend the Plan. Except as provided in Section 18
hereof, no such termination can affect options previously granted, provided that
an Offering Period may be terminated by the Board of Directors on any Exercise
Date if the Board determines that the termination of the Plan is in the best
interests of the Company and its stockholders. Except as provided in Section 18
hereof, no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. To the extent necessary to
comply with Rule 16b-3 or under Section 423 of the Code (or any successor rule
or provision or any other applicable law or regulation), the Company shall
obtain stockholder approval in such a manner and to such a degree as required.

(b) Without stockholder consent and without regard to whether
any participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

20. NOTICES. All notices or other communications by a participant to
the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

21. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued
with respect to an option unless the exercise of such option and the issuance
and delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

-9-B-9

As a condition to the exercise of an option, the Company may
require the person exercising such option to represent and warrant at the time
of any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

22. TERM OF PLAN. The Plan shall become effective upon the earlier
to occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 19 hereof.

23. AUTOMATIC TRANSFER TO LOW PRICE OFFERING PERIOD. To the extent
permitted by Rule 16b-3 of the Exchange Act, if the Fair Market Value of the
Common Stock on any Exercise Date in an Offering Period is lower than the Fair
Market Value of the Common Stock on the Enrollment Date of such Offering Period,
then all participants in such Offering Period shall be automatically withdrawn
from such Offering Period immediately after the exercise of their option on such
Exercise Date and automatically re-enrolled in the immediately following
Offering Period as of the first day thereof.
