--------------------------------------------------------------------------------

(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, the
Administrator shall have the authority in its discretion:

(i) to determine the Fair Market Value;

(ii) to select the Service Providers to whom Options and Stock Purchase Rights
may from time to time be granted hereunder;

(iii) to determine the number of Shares to be covered by each such award granted
hereunder;

(iv) to approve forms of agreement for use under the Plan;

(v) to determine the terms and conditions of any Option or Stock Purchase Right
granted hereunder. Such terms and conditions include, but are not limited to,
the exercise price, the time or times when Options or Stock Purchase Rights may
be exercised (which may be based on performance criteria), any vesting

the Shares to be withheld shall be determined on the date that the amount of tax
to be withheld is to be determined. All elections by Optionees to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

(viii) to construe and interpret the terms of the Plan and Options granted

(c) Effect of Administrator’s Decision. All decisions, determinations and
interpretations of the Administrator shall be final and binding on all
Optionees.

5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may be
granted to Service Providers. Incentive Stock Options may be granted only to
Employees.

6. Limitations.

(a) Incentive Stock Option Limit. Each Option shall be designated in the Option
Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designation, to the extent that the aggregate Fair
Market Value of the Shares

 

-4-

--------------------------------------------------------------------------------

with respect to which Incentive Stock Options are exercisable for the first time
by the Optionee during any calendar year (under all plans of the Company and any
Parent or Subsidiary) exceeds $100,000, such Options shall be treated as
Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock
Options shall be taken into account in the order in which they were granted. The
Fair Market Value of the Shares shall be determined as of the time the Option
with respect to such Shares is granted.

(b) At-Will Employment. Neither the Plan nor any Option or Stock Purchase Right
shall confer upon any Optionee any right with respect to continuing the
Optionee’s relationship as a Service Provider with the Company, nor shall it
interfere in any way with his or her right or the Company’s right to terminate
such relationship at any time, with or without cause, and with or without
notice.

7. Term of Plan. Subject to stockholder approval in accordance with Section 19,
the Plan shall become effective upon its adoption by the Board. Unless sooner
terminated under Section 15, it shall continue in effect for a term of ten
(10) years from the later of (i) the effective date of the Plan, or (ii) the
earlier of the most recent Board or stockholder approval of an increase in the
number of Shares reserved for issuance under the Plan.

8. Term of Option. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. 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 or such shorter term as may be provided in the
Option Agreement.

9. Option Exercise Price and Consideration.

(a) Exercise Price. The per share exercise price for the Shares to be issued
upon exercise of an Option shall be such price as is determined by the
Administrator, 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 grant of such 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 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 Administrator.

(iii) Notwithstanding the foregoing, Options may be granted with a per Share
exercise price other than as required above pursuant to a merger or other
corporate transaction.

 

-5-

--------------------------------------------------------------------------------

(b) Forms of Consideration. 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). Such consideration may consist of,
without limitation, (i) cash, (ii) check, (iii) promissory note, (iv) other
Shares, provided Shares that were acquired directly from the Company (x) 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 such Option shall be exercised,
(v) consideration received by the Company under a cashless exercise program
implemented by the Company in connection with the Plan, or (vi) any combination
of the foregoing methods of payment. In making its determination as to the type
of consideration to accept, the Administrator shall consider if acceptance of
such consideration may be reasonably expected to benefit the Company.

10. Exercise of Option.

(a) Procedure for Exercise; Rights as a Stockholder. Any Option granted
hereunder shall be exercisable according to the terms hereof at such times and
under such conditions as determined by the Administrator and set forth in the
Option Agreement. An Option may not be exercised for a fraction of a Share.

An Option shall be deemed exercised when the Company receives: (i) written or
electronic notice of exercise (in accordance with the Option Agreement) from the
person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised. Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan. Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse. Until the Shares
are issued (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a stockholder shall exist with respect to the
Shares, notwithstanding the exercise of the Option. The Company shall issue (or
cause to be issued) such Shares promptly after the Option is exercised. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the Shares are issued, except as provided in Section 13 of
the Plan.

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

(b) Termination of Relationship as a Service Provider. If an Optionee ceases to
be a Service Provider, such Optionee may exercise his or her Option within such
period of time as is specified in the Option Agreement to the extent that the
Option is vested on the date of termination (but in no event later than the
expiration of the term of the Option as set forth in the Option Agreement). In
the absence of a specified time in the Option Agreement, the Option shall remain
exercisable for three (3) months following the Optionee’s termination. If, on
the date of termination, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested 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 by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

 

-6-

--------------------------------------------------------------------------------

(c) Disability of Optionee. If an Optionee ceases to be a Service Provider as a
result of the Optionee’s Disability, the Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement to the extent
the Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Option Agreement). In
the absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee’s termination. If, on
the date of termination, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested 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. If an Optionee dies while a Service Provider, the Option
may be exercised within such period of time as is specified in the Option
Agreement (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 designated beneficiary,
provided such beneficiary has been designated prior to Optionee’s death in a
form acceptable to the Administrator. If no such beneficiary has been designated
by the Optionee, then such Option may be exercised by the personal
representative of the Optionee’s estate or by the person(s) to whom the Option
is transferred pursuant to the Optionee’s will or in accordance with the laws of
descent and distribution. In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee’s termination. If, at the time of death, the Optionee is not vested
as to his or her entire Option, the Shares covered by the unvested portion of
the Option shall immediately revert to the Plan. If the Option is not so
exercised within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

(e) Leaves of Absence.

(i) Unless the Administrator provides otherwise, vesting of Options granted
hereunder shall be suspended during any unpaid leave of absence.

(ii) A Service Provider shall not cease to be an Employee in the case of (A) any
leave of absence approved by the Company or (B) transfers between locations of
the Company or between the Company, its Parent, any Subsidiary, or any
successor.

(iii) For purposes of Incentive Stock Options, no such leave may exceed ninety
(90) days, unless reemployment upon expiration of such leave is guaranteed by
statute or contract. If reemployment upon expiration of a leave of absence
approved by the Company is not so guaranteed, then three (3) months following
the 91st day of such leave, any Incentive Stock Option held by the Optionee
shall cease to be treated as an Incentive Stock Option and shall be treated for
tax purposes as a Nonstatutory Stock Option.

 

-7-

--------------------------------------------------------------------------------

11. Stock Purchase Rights.

(a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in
addition to, or in tandem with other awards granted under the Plan and/or cash
awards made outside of the Plan. After the Administrator determines that it will
offer Stock Purchase Rights under the Plan, it shall advise the offeree in
writing or electronically of the terms, conditions and restrictions related to
the offer, including the number of Shares that such person shall be entitled to
purchase, the price to be paid, and the time within which such person must
accept such offer. The offer shall be accepted by execution of a Restricted
Stock Purchase Agreement in the form determined by the Administrator.

(b) Repurchase Option. Unless the Administrator determines otherwise, the
Restricted Stock Purchase Agreement shall grant the Company a repurchase option
exercisable within 90 days of the voluntary or involuntary termination of the
purchaser’s service with the Company for any reason (including death or
disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine.

(c) Other Provisions. The Restricted Stock Purchase Agreement shall contain such
other terms, provisions and conditions not inconsistent with the Plan as may be
determined by the Administrator in its sole discretion.

(d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the
purchaser shall have rights equivalent to those of a stockholder and shall be a
stockholder when his or her purchase is entered upon the records of the duly
authorized transfer agent of the Company. No adjustment shall be made for a
dividend or other right for which the record date is prior to the date the Stock
Purchase Right is exercised, except as provided in Section 13 of the Plan.

12. Transferability of Options and Stock Purchase Rights. Unless determined
otherwise by the Administrator, Options and Stock Purchase Rights may not be
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner
other than by will or the laws of descent and distribution, and may be exercised
during the lifetime of the Optionee, only by the Optionee.

13. Adjustments; Dissolution or Liquidation: Merger or Change in Control.

(a) Adjustments. In the event that any dividend or other distribution (whether
in the form of cash, Shares, other securities, or other property),
recapitalization, stock split, reverse stock split, reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase, or exchange of
Shares or other securities of the Company, or other change in the corporate
structure of the Company affecting the Shares occurs, the Administrator, in
order to prevent diminution or enlargement of the benefits or potential benefits
intended to be made available under the Plan, shall proportionately adjust the
number and class of Shares that may be delivered under the Plan and/or the
number, class, and price of Shares covered by each outstanding Option or Stock
Purchase Right.

(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. To the
extent it has not been previously exercised, an Option or Stock Purchase Right
will terminate immediately prior to the consummation of such proposed action.

 

-8-

--------------------------------------------------------------------------------

(c) Merger or Change in Control. In the event of a merger of the Company with or
into another corporation, or a Change in Control, each outstanding Option and
Stock Purchase Right shall be assumed or an equivalent option substituted by the
successor corporation or a Parent or Subsidiary of the successor corporation. In
the event that the successor corporation in a merger or Change in Control
refuses to assume or substitute for the Option or Stock Purchase Right, then the
Optionee shall fully vest in and have the right to exercise the Option or Stock
Purchase Right as to all of the Optioned Stock, including Shares as to which it
would not otherwise be vested or exercisable. If an Option or Stock Purchase
Right becomes fully vested and exercisable in lieu of assumption or substitution
in the event of a merger or Change in Control, the Administrator shall notify
the Optionee in writing or electronically that the Option or Stock Purchase
Right shall be fully exercisable for a period of fifteen (15) days from the date
of such notice, and the Option or Stock Purchase Right shall terminate upon
expiration of such period. For the purposes of this paragraph, the Option or
Stock Purchase Right shall be considered assumed if, following the merger or
Change in Control, the option or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option or Stock Purchase Right
immediately prior to the merger or Change in Control, the consideration (whether
stock, cash, or other securities or property) received in the merger or Change
in Control 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 chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger or
Change in Control is 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 or
Stock Purchase Right, for each Share of Optioned Stock subject to the Option or
Stock Purchase Right, 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 or Change in Control.

14. Time of Granting Options and Stock Purchase Rights. The date of grant of an
Option or Stock Purchase Right shall, for all purposes, be the date on which the
Administrator makes the determination granting such Option or Stock Purchase
Right, or such later date as is determined by the Administrator. Notice of the
determination shall be given to each Service Provider to whom an Option or Stock
Purchase Right is so granted within a reasonable time after the date of such
grant.

15. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend
or terminate the Plan.

(b) Stockholder Approval. The Board shall obtain stockholder approval of any
Plan amendment to the extent necessary and desirable to comply with Applicable
Laws.

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or
termination of the Plan shall impair the rights of any Optionee, unless mutually
agreed otherwise between the Optionee and the Administrator, which agreement
must be in writing and signed by the Optionee and the Company. Termination of
the Plan shall not affect the Administrator’s ability to exercise the powers
granted to it hereunder with respect to Options granted under the Plan prior to
the date of such termination.

 

-9-

--------------------------------------------------------------------------------

16. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an
Option or Stock Purchase Right unless the exercise of such Option or Stock
Purchase Right and the issuance and delivery of such Shares shall comply with
Applicable Laws and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise of an Option or
Stock Purchase Right, the Administrator 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.

17. Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company’s counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

18. Reservation of Shares. The Company, during the term of this Plan, shall at
all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

19. Stockholder Approval. The Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months after the date the Plan is
adopted. Such stockholder approval shall be obtained in the degree and manner
required under Applicable Laws.

provisions of the Plan and this

 

-2-

--------------------------------------------------------------------------------

Addendum, the Administrator, shall, in its discretion, determine the persons to
whom Options or Stock Purchase Rights will be granted under this Addendum and
all of the terms and conditions of such Options or Stock Purchase Rights. The
Administrator will have the full authority to make all determinations called for
under this Addendum and to interpret the Addendum and each Option or Stock
Purchase Right. All such determinations shall be final and binding on all
persons having an interest in the Addendum or any Option or Stock Purchase
Right. The Administrator may terminate or amend the Plan or this Addendum at any
time in accordance with Section 15 of the Plan.

 

6. ELIGIBILITY

Options or Stock Purchase Rights may be granted under this Addendum only to
persons who are Employees “resident” in India in accordance with the provisions
of FEMA, excluding, however, any Employee who is a Promoter or belongs to the
Promoter Group or who is a Director who either by himself or through his
relative or through any body corporate, directly or indirectly, holds more than
ten percent (10%) of the outstanding equity shares of the Company. Eligibility
in accordance with this Section shall not entitle any person to be granted an
Option or Stock Purchase Right, or, having been granted an Option, to be granted
an additional Option or Stock Purchase Right. The Administrator shall, based on
the performance, potential for future contribution to the Company, integrity,
number of employment years and any other factor(s) as deemed fit by the
Administrator in its discretion, form the basis for determining the quantum for
awarding the Options or Stock Purchase Rights, if any. The number of Shares
subject to Options or Stock Purchase Rights that may be granted under the Plan
to an Employee shall not be more than 210,000 Shares.

 

7. TERMS AND CONDITIONS OF OPTIONS

Each Option shall be evidenced by an Option Agreement in the form approved by
the Administrator; provided, however, that each Option Agreement shall comply
with the terms specified below and, to the extent not inconsistent with such
terms, with the terms specified by the Plan.

 

  7.1 VESTING: Subject to the Plan and the Option Agreement, Options shall
become exerciseable upon such schedule as approved by the Administrator.

 

  7.2 EXERCISE: An Option may not be exercised for a fraction of a Share. An
Option shall be deemed exercised when the Company receives (i) written or
electronic notice of exercise (in accordance with the Option Agreement) from the
person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised.

 

  7.3 EXERCISE PRICE: The exercise price for each Option shall be established at
the discretion of the Administrator based on Fair Market Value on the date of
grant of the Option in accordance with the terms of the Plan.

 

  7.4 RIGHT TO EXERCISE OF OPTIONS AND EFFECT OF TERMINATION OF SERVICE: Subject
to the provisions of the Plan, if an Optionee ceases to be an Employee upon
termination of his service, the Optionee may exercise his or her Option within
such period of time as is specified in the Option Agreement to the extent that
the Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Option Agreement).

 

-3-

--------------------------------------------------------------------------------

For the purposes of each Option granted pursuant to this Addendum, “termination
of service” or words of similar meaning shall mean the time of occurrence of any
of the following, whichever is the first to occur:

 

  (a) the death of the Optionee, provided that the Optionee’s service has not
otherwise previously terminated;

 

  (b) the termination of any minimum statutory notice period to which the
Optionee is entitled pursuant to applicable employment laws, unless the Company
employing the Optionee, in its discretion, designates a later time of
termination of service;

 

  (c) the Indian Subsidiary ceases to be a Subsidiary of the Company; or

 

  (d) in all other cases, the time of the cessation of the Optionee’s active
service as determined by the Company or the Indian Subsidiary, in its
discretion;

provided, however, that it is expressly intended that “termination of service”
for all purposes of any such Option shall not mean and shall not be construed to
mean the time of expiration of any period of reasonable notice that the Indian
Subsidiary or the Company may be required by law to provide to the Optionee.
Subject to the foregoing, the Company, in its discretion, shall determine
whether the Optionee’s service has terminated and the effective date of such
termination of service.

 

  7.5 PAYMENT OF EXERCISE PRICE: Payment of the exercise price for the number of
Shares being purchased pursuant to any Option shall be made only by one of the
following:

 

  (a) Except as otherwise provided below, payment of the exercise price for the
number of Shares being purchased pursuant to any Option shall be made (i) in
cash, by check or cash equivalent, (ii) pursuant to a cashless exercise program
implemented by the Company in connection with the Plan, (iii) by such other
consideration as may be approved by the Administrator from time to time to the
extent permitted by Applicable Law, or (iv) by any combination thereof.
Notwithstanding the foregoing, the above procedures will be subject to
compliance with the applicable regulations under FEMA.

The Administrator may at any time or from time to time, by approval of or by
amendment to the standard forms of Option Agreement or by other means, grant
Options which do not permit all of the foregoing forms of consideration to be
used in payment of the exercise price or which otherwise restrict one or more
forms of consideration.

 

  7.6

TAX WITHHOLDING: The Company shall have the right, to deduct from the shares of
Common Stock issuable upon the exercise of an Option, or to accept from the
Optionee the tender of, a number of whole shares of Common Stock having a Fair
Market Value, as determined by the Company, equal to all or any part of the
taxes, if any, required by law to be withheld by the Company or the Indian
Subsidiary with respect to such Option or the Shares acquired upon the exercise
thereof. Alternatively or in addition, in its discretion, the Company or the
Indian Subsidiary shall have the right to require the

 

-4-

--------------------------------------------------------------------------------

 

Optionee, through payroll withholding, cash payment or otherwise, including by
means of a Cashless Exercise, to make adequate provision for any such tax
withholding obligations of the Company or the Indian Subsidiary arising in
connection with the Option or the shares acquired upon the exercise thereof. The
Fair Market Value of any shares of Common Stock withheld or tendered to satisfy
any such tax withholding obligations shall not exceed the amount determined by
the applicable minimum statutory withholding rates. The Company shall have no
obligation to deliver shares of Common Stock until such tax withholding
obligations have been satisfied by the Optionee.

 

  7.7 CURRENCY EXCHANGE RATES: Except as otherwise determined by the
Administrator, all monetary values under this Addendum, including, without
limitation, the Fair Market Value per Share and the exercise price of each
Option shall be stated in US Dollars. Any changes or fluctuations in the
exchange rate at which amounts paid by Optionees in currencies other than US
Dollars are converted into US Dollars or amounts paid to Optionees in US Dollars
are converted into currencies other than US Dollars shall be borne solely by the
Optionee.

 

  7.8 NON-TRANSFERABILITY OF OPTIONS: The Options and Stock purchase Rights 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.

 

8. STOCK PURCHASE RIGHTS

The issue of Stock Purchase Rights to Employees shall be governed by the
provisions of Section 11 of the Plan, provided they do not conflict with this
Addendum, and the FEMA.

 

9. COMPLIANCE WITH LAW

In addition to the requirements set forth in the Plan, the grant of Options
pursuant to this Addendum and the issuance of Shares upon exercise of such
Options shall be subject to compliance with all applicable requirements of the
law of the Republic of India.
