          (a) Plan Administrator.

               (i) Administration with Respect to Directors and Officers. Prior

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 Applicable
Laws. On or after the Registration Date, with respect to grants of Awards to
Directors or Employees who are also Officers or Directors 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
Applicable Laws and to permit such grants and related transactions under the

Rule 16b-3. Once appointed, such Committee shall continue to serve in its
designated capacity until otherwise directed by the Board.

               (ii) Administration With Respect to Consultants and Other
Employees. With respect to grants of Awards to Employees or Consultants who are
neither Directors nor Officers of the Company, the Plan shall be administered by

the Plan under Section 162(m) of the Code expires, as set forth in Section 18
below, grants of Awards to any Covered Employee intended to qualify as
Performance-Based Compensation shall be made only by a Committee (or
subcommittee of a Committee) which is comprised solely of two or more Directors
eligible to serve on a committee making Awards qualifying as Performance-Based
Compensation. In the case of such Awards granted to Covered Employees,
references to the “Administrator” or to a “Committee” shall be deemed to be
references to such Committee or subcommittee.

               (iv) Officer Authorization to Grant Awards. The Board may
authorize one or more Officers to grant Awards subject to such limitations as
the Board determines from time to time.

7

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

 

          (b) Multiple Administrative Bodies. The Plan may be administered by
different bodies with respect to Directors, Officers, Consultants, and Employees

               (i) to select the Employees, Directors and Consultants to whom
Awards may be granted from time to time hereunder;

               (ii) to determine whether and to what extent Awards are granted
hereunder;

               (iii) to determine the number of Shares or the amount of other
consideration to be covered by each Award granted hereunder;

               (v) to determine the terms and conditions of any Award granted
hereunder;

               (vi) to grant Awards to Employees, Directors and Consultants
employed outside the United States on such terms and conditions different from
those specified in the Plan as may, in the judgment of the Administrator, be
necessary or desirable to further the purpose of the Plan;

               (vii) to amend the terms of any outstanding Award granted under
the Plan, provided that (A) any amendment that would adversely affect the
Grantee’s rights under an outstanding Award shall not be made without the
Grantee’s written consent, (B) the reduction of the exercise price of any Option
awarded under the Plan shall be subject to stockholder approval and
(C) canceling an Option at a time when its exercise price exceeds the Fair
Market Value of the underlying Shares, in exchange for another Option,
Restricted Stock, or other Award shall be subject to stockholder approval,
unless the cancellation and exchange occurs in connection with a Corporate
Transaction.

               (viii) to construe and interpret the terms of the Plan and
Awards, including without limitation, any notice of award or Award Agreement,
granted pursuant to the Plan; and

               (ix) to take such other action, not inconsistent with the terms
of the Plan, as the Administrator deems appropriate.

          (d) Indemnification. In addition to such other rights of

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

 

shall be defended and indemnified by the Company to the extent permitted by law
on an after-tax basis against all reasonable expenses, including attorneys’
fees, actually and necessarily incurred in connection with the defense of any
claim, investigation, action, suit or proceeding, or in connection with any
appeal therein, to which they or any of them may be a party by reason of any
action taken or failure to act under or in connection with the Plan, or any
Award granted hereunder, and against all amounts paid by them in settlement
thereof (provided such settlement is approved by the Company) or paid by them in
satisfaction of a judgment in any such claim, investigation, action, suit or
proceeding, except in relation to matters as to which it shall be adjudged in
such claim, investigation, action, suit or proceeding that such person is liable
for gross negligence, bad faith or intentional misconduct; provided, however,
that within thirty (30) days after the institution of such claim, investigation,
action, suit or proceeding, such person shall offer to the Company, in writing,
the opportunity at the Company’s expense to defend the same.

     5. Eligibility. Awards other than Incentive Stock Options may be granted to
Employees, Directors and Consultants. Incentive Stock Options may be granted
only to Employees of the Company or a Parent or a Subsidiary of the Company. An
Employee, Director or Consultant who has been granted an Award may, if otherwise
eligible, be granted additional Awards. Awards may be granted to such Employees,
Directors or Consultants who are residing in non-U.S. jurisdictions as the
Administrator may determine from time to time.

     6. Terms and Conditions of Awards.

          (a) Types of Awards. The Administrator is authorized under the Plan to
award any type of arrangement to an Employee, Director or Consultant that is not
inconsistent with the provisions of the Plan and that by its terms involves or
might involve the issuance of (i) Shares, (ii) cash or (iii) an Option, a SAR,
or similar right with a fixed or variable price related to the Fair Market Value
of the Shares and with an exercise or conversion privilege related to the
passage of time, the occurrence of one or more events, or the satisfaction of
performance criteria or other conditions. Such awards include, without
limitation, Options, SARs, sales or bonuses of Restricted Stock, Restricted
Stock Units or Dividend Equivalent Rights, and an Award may consist of one such
security or benefit, or two (2) or more of them in any combination or
alternative.

          (b) Designation of Award. Each Award shall be designated in the Award
Agreement. In the case of an Option, the Option shall be designated as either an
Incentive Stock Option or a Non-Qualified Stock Option. However, notwithstanding
such designation, an Option will qualify as an Incentive Stock Option under the
Code only to the extent the $100,000 dollar limitation of Section 422(d) of the
Code is not exceeded. The $100,000 limitation of Section 422(d) of the Code is
calculated based on the aggregate Fair Market Value of the Shares subject to
Options designated as Incentive Stock Options which become exercisable for the
first time by a Grantee during any calendar year (under all plans of the Company
or any Parent or Subsidiary of the Company). For purposes of this calculation,
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 grant date of the relevant Option.

9

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

 

          (c) Conditions of Award. Subject to the terms of the Plan, the
Administrator shall determine the provisions, terms, and conditions of each
Award including, but not limited to, the Award vesting schedule, repurchase
provisions, rights of first refusal, forfeiture provisions, form of payment
(cash, Shares, or other consideration) upon settlement of the Award, payment
contingencies, and satisfaction of any performance criteria. The performance
criteria established by the Administrator may be based on any one of, or
combination of, the following: (i) increase in share price, (ii) earnings per
share, (iii) total stockholder return, (iv) operating margin, (v) gross margin,
(vi) return on equity, (vii) return on assets, (viii) return on investment, (ix)
operating income, (x) net operating income, (xi) pre-tax profit, (xii) cash
flow, (xiii) revenue, (xiv) expenses, (xv) earnings before interest, taxes and
depreciation, (xvi) economic value added and (xvii) market share. The
performance criteria may be applicable to the Company, Related Entities and/or
any individual business units of the Company or any Related Entity. Partial
achievement of the specified criteria may result in a payment or vesting
corresponding to the degree of achievement as specified in the Award Agreement.

          (d) Acquisitions and Other Transactions. The Administrator may issue
Awards under the Plan in settlement, assumption or substitution for, outstanding
awards or obligations to grant future awards in connection with the Company or a
Related Entity acquiring another entity, an interest in another entity or an
additional interest in a Related Entity whether by merger, stock purchase, asset
purchase or other form of transaction.

          (e) Deferral of Award Payment. The Administrator may establish one or
more programs under the Plan to permit selected Grantees the opportunity to
elect to defer receipt of consideration upon exercise of an Award, satisfaction
of performance criteria, or other event that absent the election would entitle
the Grantee to payment or receipt of Shares or other consideration under an
Award. The Administrator may establish the election procedures, the timing of
such elections, the mechanisms for payments of, and accrual of interest or other
earnings, if any, on amounts, Shares or other consideration so deferred, and
such other terms, conditions, rules and procedures that the Administrator deems
advisable for the administration of any such deferral program.

          (f) Separate Programs. The Administrator may establish one or more
separate programs under the Plan for the purpose of issuing particular forms of
Awards to one or more classes of Grantees on such terms and conditions as
determined by the Administrator from time to time.

          (g) Individual Option and SAR Limit. Following the date that the
exemption from application of Section 162(m) of the Code described in Section 18
(or any exemption having similar effect) ceases to apply to Awards, the maximum
number of Shares with respect to which Options and SARs may be granted to any
Grantee in any fiscal year of the Company shall be 2,000,000 Shares. In
connection with a Grantee’s commencement of Continuous Service, a Grantee may be
granted Options and SARs for up to an additional 2,000,000 Shares which shall
not count against the limit set forth in the previous sentence. The foregoing
limitations shall be adjusted proportionately in connection with any change in
the Company’s capitalization pursuant to Section 10, below. To the extent
required by Section 162(m) of the Code or the regulations thereunder, in
applying the foregoing limitations with respect to a Grantee, if any Option or
SAR is canceled, the canceled Option or SAR shall continue to count against the
maximum number of

10

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

 

Shares with respect to which Options and SARs may be granted to the Grantee. For
this purpose, the repricing of an Option (or in the case of a SAR, the base
amount on which the stock appreciation is calculated is reduced to reflect a
reduction in the Fair Market Value of the Common Stock) shall be treated as the
cancellation of the existing Option or SAR and the grant of a new Option or SAR.

          (h) Early Exercise. The Award Agreement may, but need not, include a
provision whereby the Grantee may elect at any time while an Employee, Director
or Consultant to exercise any part or all of the Award prior to full vesting of
the Award. Any unvested Shares received pursuant to such exercise may be subject
to a repurchase right in favor of the Company or a Related Entity or to any
other restriction the Administrator determines to be appropriate.

          (i) Term of Award. The term of each Award shall be the term stated in
the Award Agreement, provided, however, that the term of an Incentive Stock
Option 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 a Grantee 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 of the Company, the term of the Incentive Stock Option shall be
five (5) years from the date of grant thereof or such shorter term as may be
provided in the Award Agreement. Notwithstanding the foregoing, the specified
term of any Award shall not include any period for which the Grantee has elected
to defer the receipt of the Shares or cash issuable pursuant to the Award.

          (j) Transferability of Awards. Incentive Stock 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 Grantee, only by the Grantee.
Non-Qualified Stock Options and other Awards shall be transferable (i) by will
or by the laws of descent and distribution and (ii) during the lifetime of the
Grantee, to the extent and in the manner authorized by the Administrator.
Notwithstanding the foregoing, the Grantee may designate one or more
beneficiaries of the Grantee’s Award in the event of the Grantee’s death on a
beneficiary designation form provided by the Administrator.

          (k) Time of Granting Awards. The date of grant of an Award shall for
all purposes be the date on which the Administrator makes the determination to
grant such Award, or such other later date as is determined by the
Administrator.

     7. Award Exercise or Purchase Price, Consideration and Taxes.

          (a) Exercise or Purchase Price. The exercise or purchase price, if
any, for an Award shall be as follows:

               (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 of the Company, the per Share exercise price shall be not less than
one hundred ten percent (110%) of the Fair Market Value per Share on the date of
grant; or

11

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

 

                    (B) granted to any Employee other than an Employee described
in the preceding paragraph, the per Share exercise price shall be not less than
one hundred percent (100%) of the Fair Market Value per Share on the date of
grant.

               (ii) In the case of a Non-Qualified Stock Option, the per Share
exercise price shall be not less than eighty-five percent (85%) of the Fair
Market Value per Share on the date of grant unless otherwise determined by the
Administrator.

               (iii) In the case of Awards intended to qualify as
Performance-Based Compensation, the exercise or purchase price, if any, shall be
not less than one hundred percent (100%) of the Fair Market Value per Share on
the date of grant.

               (iv) In the case of other Awards, such price as is determined by
the Administrator.

               (v) Notwithstanding the foregoing provisions of this
Section 7(a), in the case of an Award issued pursuant to Section 6(d), above,
the exercise or purchase price for the Award shall be determined in accordance
with the provisions of the relevant instrument evidencing the agreement to issue
such Award.

          (b) Consideration. Subject to Applicable Laws, the consideration to be
paid for the Shares to be issued upon exercise or purchase of an Award including
the method of payment, shall be determined by the Administrator. In addition to
any other types of consideration the Administrator may determine, the
Administrator is authorized to accept as consideration for Shares issued under
the Plan the following provided that the portion of the consideration equal to
the par value of the Shares must be paid in cash or other legal consideration
permitted by the Delaware General Corporation Law:

               (i) cash;

               (ii) check;

               (iii) delivery of Grantee’s promissory note with such recourse,
interest, security, and redemption provisions as the Administrator determines as
appropriate (but only to the extent that the acceptance or terms of the
promissory note would not violate an Applicable Law);

               (iv) if the exercise or purchase occurs on or after the
Registration Date, surrender of Shares or delivery of a properly executed form
of attestation of ownership of Shares as the Administrator may require which
have a Fair Market Value on the date of surrender or attestation equal to the
aggregate exercise price of the Shares as to which said Award shall be
exercised, provided, however, that Shares acquired under the Plan or any other
equity compensation plan or agreement of the Company must have been held by the
Grantee for a period of more than six (6) months (and not used for another Award
exercise by attestation during such period);

               (v) with respect to Options, if the exercise occurs on or after
the Registration Date, payment through a broker-dealer sale and remittance
procedure pursuant to

12

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

 

which the Grantee (A) shall provide written instructions to a Company designated
brokerage firm to effect the immediate sale of some or all of the purchased
Shares and remit to the Company sufficient funds to cover the aggregate exercise
price payable for the purchased Shares and (B) shall provide written directives
to the Company to deliver the certificates for the purchased Shares directly to
such brokerage firm in order to complete the sale transaction; or

               (vi) any combination of the foregoing methods of payment.

The Administrator may at any time or from time to time, by adoption of or by
amendment to the standard forms of Award Agreement described in
Section 4(c)(iv), or by other means, grant Awards which do not permit all of the
foregoing forms of consideration to be used in payment for the Shares or which
otherwise restrict one or more forms of consideration.

          (c) Taxes. No Shares shall be delivered under the Plan to any Grantee
or other person until such Grantee or other person has made arrangements
acceptable to the Administrator for the satisfaction of any non-U.S., federal,
state, or local income and employment tax withholding obligations, including,
without limitation, obligations incident to the receipt of Shares. Upon exercise
or vesting of an Award the Company shall withhold or collect from Grantee an
amount sufficient to satisfy such tax obligations, including, but not limited
too, by surrender of the whole number of Shares covered by the Award sufficient
to satisfy the minimum applicable tax withholding obligations incident to the
exercise or vesting of an Award.

     8. Exercise of Award.

          (a) Procedure for Exercise; Rights as a Stockholder

               (i) Any Award granted hereunder shall be exercisable at such
times and under such conditions as determined by the Administrator under the
terms of the Plan and specified in the Award Agreement.

               (ii) An Award 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 Award by the person entitled to exercise the Award and full payment for the
Shares with respect to which the Award is exercised has been made, including, to
the extent selected, use of the broker-dealer sale and remittance procedure to
pay the purchase price as provided in Section 7(b)(v).

          (b) Exercise of Award Following Termination of Continuous Service.

               (i) An Award may not be exercised after the termination date of
such Award set forth in the Award Agreement and may be exercised following the
termination of a Grantee’s Continuous Service only to the extent provided in the
Award Agreement.

               (ii) Where the Award Agreement permits a Grantee to exercise an
Award following the termination of the Grantee’s Continuous Service for a
specified period, the Award shall terminate to the extent not exercised on the
last day of the specified period or the last day of the original term of the
Award, whichever occurs first.

13

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

 

               (iii) Any Award designated as an Incentive Stock Option to the
extent not exercised within the time permitted by law for the exercise of
Incentive Stock Options following the termination of a Grantee’s Continuous
Service shall convert automatically to a Non-Qualified Stock Option and
thereafter shall be exercisable as such to the extent exercisable by its terms
for the period specified in the Award Agreement.

     9. Conditions Upon Issuance of Shares.

          (a) Shares shall not be issued pursuant to the exercise of an Award
unless the exercise of such Award and the issuance and delivery of such Shares
pursuant thereto shall comply with all Applicable Laws, and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

          (b) As a condition to the exercise of an Award, the Company may
require the person exercising such Award 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
Applicable Laws.

     10. Adjustments Upon Changes in Capitalization. Subject to any required
action by the stockholders of the Company, the number of Shares covered by each
outstanding Award, and the number of Shares which have been authorized for
issuance under the Plan but as to which no Awards have yet been granted or which
have been returned to the Plan, the exercise or purchase price of each such
outstanding Award, the maximum number of Shares with respect to which Options
and SARs may be granted to any Grantee in any fiscal year of the Company, as
well as any other terms that the Administrator determines require adjustment
shall be proportionately adjusted for (i) any increase or decrease in the number
of issued Shares resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Shares, or similar transaction
affecting the Shares, (ii) any other increase or decrease in the number of
issued Shares effected without receipt of consideration by the Company, or
(iii) as the Administrator may determine in its discretion, any other
transaction with respect to Common Stock including a corporate merger,
consolidation, acquisition of property or stock, separation (including a
spin-off or other distribution of stock or property), reorganization,
liquidation (whether partial or complete) or any similar transaction; 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 Administrator and its determination shall be
final, binding and conclusive. Except as the Administrator determines, 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 hereof shall be made with respect to, the number or price of Shares
subject to an Award.

     11. Corporate Transactions and Changes in Control.

          (a) Termination of Award to Extent Not Assumed in Corporate
Transaction. Effective upon the consummation of a Corporate Transaction, all
outstanding Awards under the Plan shall terminate. However, all such Awards
shall not terminate to the extent they are Assumed in connection with the
Corporate Transaction.

14

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

 

          (b) No Acceleration of Award Upon Corporate Transaction or Change in
Control. Except as provided otherwise in an individual Award Agreement, in the
event of any Corporate Transaction or Change in Control, there will not be any
acceleration of vesting or exercisability of any Award.

     12. Effective Date and Term of Plan. The Plan shall become effective upon
the earlier to occur of its adoption by the Board or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten
(10) years unless sooner terminated. Subject to Section 17 below, and Applicable
Laws, Awards may be granted under the Plan upon its becoming effective.

     13. Amendment, Suspension or Termination of the Plan.

          (a) The Board may at any time amend, suspend or terminate the Plan;
provided, however, that no such amendment shall be made without the approval of
the Company’s stockholders to the extent such approval is required by Applicable
Laws, or if such amendment would lessen the stockholder approval requirements of
Section 4(c)(vii) or this Section 13(a).

          (b) No Award may be granted during any suspension of the Plan or after
termination of the Plan.

          (c) No suspension or termination of the Plan (including termination of
the Plan under Section 12, above) shall adversely affect any rights under Awards
already granted to a Grantee.

     14. Reservation of Shares.

          (a) The Company, during the term of the Plan, will at all times
reserve and keep available such number of Shares as shall be sufficient to
satisfy the requirements of the Plan.

          (b) 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.

     15. No Effect on Terms of Employment/Consulting Relationship. The Plan
shall not confer upon any Grantee any right with respect to the Grantee’s
Continuous Service, nor shall it interfere in any way with his or her right or
the right of the Company or any Related Entity to terminate the Grantee’s
Continuous Service at any time, with or without Cause, and with or without
notice. The ability of the Company or any Related Entity to terminate the
employment

15

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

 

of a Grantee who is employed at will is in no way affected by its determination
that the Grantee’s Continuous Service has been terminated for Cause for the
purposes of this Plan.

     16. No Effect on Retirement and Other Benefit Plans. Except as specifically
provided in a retirement or other benefit plan of the Company or a Related
Entity, Awards shall not be deemed compensation for purposes of computing
benefits or contributions under any retirement plan of the Company or a Related
Entity, and shall not affect any benefits under any other benefit plan of any
kind or any benefit plan subsequently instituted under which the availability or
amount of benefits is related to level of compensation. The Plan is not a
“Retirement Plan” or “Welfare Plan” under the Employee Retirement Income
Security Act of 1974, as amended.

     17. Stockholder Approval. The grant of Incentive Stock Options under the
Plan, excluding Incentive Stock Options issued in substitution for outstanding
Incentive Stock Options pursuant to Section 424(a) of the Code, shall be subject
to approval of the Plan by the stockholders of the Company within twelve
(12) months before or after the date the Plan is adopted. Such stockholder
approval shall be obtained in the degree and manner required under Applicable
Laws. The Administrator may grant Incentive Stock Options under the Plan prior
to approval by the stockholders, but until such approval is obtained, no such
Incentive Stock Option shall be exercisable. In the event that stockholder
approval is not obtained within the twelve (12) month period provided above, all
Incentive Stock Options previously granted under the Plan shall be exercisable
as Non-Qualified Stock Options.

     18. Effect of Section 162(m) of the Code. Section 162(m) of the Code does
not apply to the Plan prior to the Registration Date or such earlier time that
the Company first becomes subject to the reporting obligations of Section 12 of
the Exchange Act. Following the Registration Date or such earlier time that the
Company first becomes subject to the reporting obligations of Section 12 of the
Exchange Act, the Plan, and all Awards (except Awards of Restricted Stock that
vest over time) issued thereunder, are intended to be exempt from the
application of Section 162(m) of the Code, which restricts under certain
circumstances the Federal income tax deduction for compensation paid by a public
company to named executives in excess of $1 million per year. The exemption is
based on Treasury Regulation Section 1.162-27(f), in the form existing on the
effective date of the Plan, with the understanding that such regulation
generally exempts from the application of Section 162(m) of the Code
compensation paid pursuant to a plan that existed before a company becomes
publicly held. Under such Treasury Regulation, this exemption is available to
the Plan for the duration of the period that lasts until the earliest of (i) the
expiration of the Plan, (ii) the material modification of the Plan, (iii) the
exhaustion of the maximum number of shares of Common Stock available for Awards
under the Plan, as set forth in Section 3(a), (iv) the first meeting of
shareholders at which directors are to be elected that occurs after the close of
the third calendar year following the calendar year in which the Company first
becomes subject to the reporting obligations of Section 12 of the Exchange Act,
or (v) such other date required by Section 162(m) of the Code and the rules and
regulations promulgated thereunder. To the extent that the Administrator
determines as of the date of grant of an Award that (i) the Award is intended to
qualify as Performance-Based Compensation and (ii) the exemption described above
is no longer available with respect to such Award, such Award shall not be
effective until any stockholder approval required under Section 162(m) of the
Code has been obtained.

16

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

 

     19. Unfunded Obligation. Grantees shall have the status of general
unsecured creditors of the Company. Any amounts payable to Grantees pursuant to
the Plan shall be unfunded and unsecured obligations for all purposes,
including, without limitation, Title I of the Employee Retirement Income
Security Act of 1974, as amended. Neither the Company nor any Related Entity
shall be required to segregate any monies from its general funds, or to create
any trusts, or establish any special accounts with respect to such obligations.
The Company shall retain at all times beneficial ownership of any investments,
including trust investments, which the Company may make to fulfill its payment
obligations hereunder. Any investments or the creation or maintenance of any
trust or any Grantee account shall not create or constitute a trust or fiduciary
relationship between the Administrator, the Company or any Related Entity and a
Grantee, or otherwise create any vested or beneficial interest in any Grantee or
the Grantee’s creditors in any assets of the Company or a Related Entity. The
Grantees shall have no claim against the Company or any Related Entity for any
changes in the value of any assets that may be invested or reinvested by the
Company with respect to the Plan.

     20. Construction. Captions and titles contained herein are for convenience
only and shall not affect the meaning or interpretation of any provision of the
Plan. Except when otherwise indicated by the context, the singular shall include
the plural and the plural shall include the singular. Use of the term “or” is
not intended to be exclusive, unless the context clearly requires otherwise.

Award Number: ___________

GCA HOLDINGS, INC. 2005 STOCK INCENTIVE PLAN

STOCK OPTION AWARD AGREEMENT

     1. Grant of Option. GCA Holdings, Inc., a Delaware corporation (the
“Company”), hereby grants to the Grantee (the “Grantee”) named in the Notice of
Stock Option Award (the “Notice”), an option (the “Option”) to purchase the
Total Number of Shares of Common Stock subject to the Option (the “Shares”) set
forth in the Notice, at the Exercise Price per Share set forth in the Notice
(the “Exercise Price”) subject to the terms and provisions of the Notice, this
Stock Option Award Agreement (the “Option Agreement”) and the Company’s 2005
Stock Incentive Plan, as amended from time to time (the “Plan”), which are
incorporated herein by reference. Unless otherwise defined herein, the terms
defined in the Plan shall have the same defined meanings in this Option
Agreement.

     If designated in the Notice as an Incentive Stock Option, the Option is
intended to qualify as an Incentive Stock Option as defined in Section 422 of
the Code. However, notwithstanding such designation, the Option will qualify as
an Incentive Stock Option under the Code only to the extent the $100,000 dollar
limitation of Section 422(d) of the Code is not exceeded. The $100,000
limitation of Section 422(d) of the Code is calculated based on the aggregate
Fair Market Value of the Shares subject to options designated as Incentive Stock
Options which become exercisable for the first time by the Grantee during any
calendar year (under all plans of the Company or any Parent or Subsidiary of the
Company). For purposes of this calculation, Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the shares subject to such options shall be determined as of the grant
date of the relevant option.

     2. Exercise of Option.

          (a) Right to Exercise. The Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice and with the
applicable provisions of the Plan and this Option Agreement. The Option shall be
subject to the provisions of Section 11 of the Plan [INSERT IF OPTIONEE TO
RECEIVE ACCELERATION: and the Notice] relating to the exercisability or
termination of the Option in the event of a Corporate Transaction or Change in
Control. The Grantee shall be subject to reasonable limitations on the number of
requested exercises during any monthly or weekly period as determined by the
Administrator. In no event shall the Company issue fractional Shares.

          (b) Method of Exercise. The Option shall be exercisable by delivery of
an exercise notice (a form of which is attached as Exhibit A) or by such other
procedure as specified from time to time by the Administrator which shall state
the election to exercise the Option, the whole number of Shares in respect of
which the Option is being exercised, and such other provisions as may be
required by the Administrator. The exercise notice shall be delivered in person,
by certified mail, or by such other method (including electronic transmission)
as

1

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

 

determined from time to time by the Administrator to the Company accompanied by
payment of the Exercise Price. The Option shall be deemed to be exercised upon
receipt by the Company of such notice accompanied by the Exercise Price, which,
to the extent selected, shall be deemed to be satisfied by use of the
broker-dealer sale and remittance procedure to pay the Exercise Price provided
in Section 4(d), below.

          (c) Taxes. No Shares will be delivered to the Grantee or other person
pursuant to the exercise of the Option until the Grantee or other person has
made arrangements acceptable to the Administrator for the satisfaction of
applicable income tax and employment tax withholding obligations, including,
without limitation, such other tax obligations of the Grantee incident to the
receipt of Shares. Upon exercise of the Option, the Company or the Grantee’s
employer may offset or withhold (from any amount owed by the Company or the
Grantee’s employer to the Grantee) or collect from the Grantee or other person
an amount sufficient to satisfy such tax withholding obligations.

     3. Grantee’s Representations. The Grantee understands that neither the
Option nor the Shares exercisable pursuant to the Option have been registered
under the Securities Act of 1933, as amended or any United States securities
laws. In the event the Shares purchasable pursuant to the exercise of the Option
have not been registered under the Securities Act of 1933, as amended, at the
time the Option is exercised, the Grantee shall, if requested by the Company,
concurrently with the exercise of all or any portion of the Option, deliver to
the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B.

     4. Method of Payment. Payment of the Exercise Price shall be made by any of
the following, or a combination thereof, at the election of the Grantee;
provided, however, that such exercise method does not then violate any
Applicable Law, provided further, that the portion of the Exercise Price equal
to the par value of the Shares must be paid in cash or other legal consideration
permitted by the Delaware General Corporation Law:

          (a) cash;

          (b) check;

          (c) if the exercise occurs on or after the Registration Date,
surrender of Shares or delivery of a properly executed form of attestation of
ownership of Shares as the Administrator may require which have a Fair Market
Value on the date of surrender or attestation equal to the aggregate Exercise
Price of the Shares as to which the Option is being exercised, provided,
however, that Shares acquired under the Plan or any other equity compensation
plan or agreement of the Company must have been held by the Grantee for a period
of more than six (6) months (and not used for another Award exercise by
attestation during such period); or

          (d) if the exercise occurs on or after the Registration Date, payment
through a broker-dealer sale and remittance procedure pursuant to which the
Grantee (i) shall provide written instructions to a Company-designated brokerage
firm to effect the immediate sale of some or all of the purchased Shares and
remit to the Company sufficient funds to cover the

2

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

 

aggregate exercise price payable for the purchased Shares and (ii) shall provide
written directives to the Company to deliver the certificates for the purchased
Shares directly to such brokerage firm in order to complete the sale
transaction.

     5. Termination or Change of Continuous Service. In the event the Grantee’s
Continuous Service terminates, other than for Cause, the Grantee may, but only
during the Post-Termination Exercise Period, exercise the portion of the Option
that was vested at the date of such termination (the “Termination Date”). The
Post-Termination Exercise Period shall commence on the Termination Date. In the
event of termination of the Grantee’s Continuous Service for Cause, the
Grantee’s right to exercise the Option shall, except as otherwise determined by
the Administrator, terminate concurrently with the termination of the Grantee’s
Continuous Service (also the “Termination Date”). In no event, however, shall
the Option be exercised later than the Expiration Date set forth in the Notice.
In the event of the Grantee’s change in status from Employee, Director or
Consultant to any other status of Employee, Director or Consultant, the Option
shall remain in effect and the Option shall continue to vest in accordance with
the Vesting Schedule set forth in the Notice; provided, however, with respect to
any Incentive Stock Option that shall remain in effect after a change in status
from Employee to Director or Consultant, such Incentive Stock Option shall cease
to be treated as an Incentive Stock Option and shall be treated as a
Non-Qualified Stock Option on the day three (3) months and one (1) day following
such change in status. Except as provided in Sections 6 and 7 below, to the
extent that the Option was unvested on the Termination Date, or if the Grantee
does not exercise the vested portion of the Option within the Post-Termination
Exercise Period, the Option shall terminate.

     6. Disability of Grantee. In the event the Grantee’s Continuous Service
terminates as a result of his or her Disability, the Grantee may, but only
within twelve (12) months commencing on the Termination Date (but in no event
later than the Expiration Date), exercise the portion of the Option that was
vested on the Termination Date; provided, however, that if such Disability is
not a “disability” as such term is defined in Section 22(e)(3) of the Code and
the Option is an Incentive Stock Option, such Incentive Stock Option shall cease
to be treated as an Incentive Stock Option and shall be treated as a
Non-Qualified Stock Option on the day three (3) months and one (1) day following
the Termination Date. To the extent that the Option was unvested on the
Termination Date, or if the Grantee does not exercise the vested portion of the
Option within the time specified herein, the Option shall terminate.
Section 22(e)(3) of the Code provides that an individual is permanently and
totally disabled if he or she is unable to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment
which can be expected to result in death or which has lasted or can be expected
to last for a continuous period of not less than twelve (12) months.

     7. Death of Grantee. In the event of the termination of the Grantee’s
Continuous Service as a result of his or her death, or in the event of the
Grantee’s death during the Post-Termination Exercise Period or during the twelve
(12) month period following the Grantee’s termination of Continuous Service as a
result of his or her Disability, the person who acquired the right to exercise
the Option pursuant to Section 8 may exercise the portion of the Option that was
vested at the date of termination within twelve (12) months commencing on the
date of death (but in no event later than the Expiration Date). To the extent
that the Option was unvested on the

3

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

 

date of death, or if the vested portion of the Option is not exercised within
the time specified herein, the Option shall terminate.

     8. Transferability of Option. The Option, if an Incentive Stock Option, may
not be transferred in any manner other than by will or by the laws of descent
and distribution and may be exercised during the lifetime of the Grantee only by
the Grantee. The Option, if a Non-Qualified Stock Option, may not be transferred
in any manner other than by will or by the laws of descent and distribution,
provided, however, that a Non-Qualified Stock Option may be transferred during
the lifetime of the Grantee to the extent and in the manner authorized by the
Administrator. Notwithstanding the foregoing, the Grantee may designate one or
more beneficiaries of the Grantee’s Incentive Stock Option or Non-Qualified
Stock Option in the event of the Grantee’s death on a beneficiary designation
form provided by the Administrator. Following the death of the Grantee, the
Option, to the extent provided in Section 7, may be exercised (a) by the person
or persons designated under the deceased Grantee’s beneficiary designation or
(b) in the absence of an effectively designated beneficiary, by the Grantee’s
legal representative or by any person empowered to do so under the deceased
Grantee’s will or under the then applicable laws of descent and distribution.
The terms of the Option shall be binding upon the executors, administrators,
heirs, successors and transferees of the Grantee.

     9. Term of Option. The Option must be exercised no later than the
Expiration Date set forth in the Notice or such earlier date as otherwise
provided herein. After the Expiration Date or such earlier date, the Option
shall be of no further force or effect and may not be exercised.

     10. Company’s Right of First Refusal.

          (a) Transfer Notice. Neither the Grantee nor a transferee (either
being sometimes referred to herein as the “Holder”) shall sell, hypothecate,
encumber or otherwise transfer any Shares or any right or interest therein
without first complying with the provisions of this Section 10 or obtaining the
prior written consent of the Company. The Holder may not sell, hypothecate,
encumber or otherwise transfer any Shares or any right or interest therein
unless such Shares are Mature Shares (as defined below). “Mature Shares” shall
mean the Shares that have been held by the Holder (and any successor Holder) for
a period of more than six (6) months. In the event the Holder desires to accept
a bona fide third-party offer for any or all of the Shares that are Mature
Shares, the Holder shall provide the Company with written notice (the “Transfer
Notice”) of:

               (i) The Holder’s intention to transfer;

               (ii) The name of the proposed transferee;

               (iii) The number of Shares to be transferred; and

               (iv) The proposed transfer price or value and terms thereof.

If the Grantee proposes to transfer any Shares to more than one transferee, the
Grantee shall provide a separate Transfer Notice for the proposed transfer to
each transferee. The Transfer Notice shall be signed by both the Grantee and the
proposed transferee and must constitute a

4

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

 

binding commitment of the Grantee and the proposed transferee for the transfer
of the Shares to the proposed transferee subject to the terms and conditions of
this Option Agreement.

          (b) Bona Fide Transfer. If the Company determines that the information
provided by the Grantee in the Transfer Notice is insufficient to establish the
bona fide nature of a proposed voluntary transfer, the Company shall give the
Grantee written notice of the Grantee’s failure to comply with the procedure
described in this Section 10, and the Grantee shall have no right to transfer
the Shares without first complying with the procedure described in this
Section 10. The Grantee shall not be permitted to transfer the Shares if the
proposed transfer is not bona fide.

          (c) First Refusal Exercise Notice. The Company shall have the right to
purchase (the “Right of First Refusal”) all but not less than all, of the Shares
which are described in the Transfer Notice (the “Offered Shares”) at any time
within ninety (90) days after receipt of the Transfer Notice (the “Option
Period”). The Offered Shares shall be repurchased at (i) the per share price or
value and in accordance with the terms stated in the Transfer Notice (subject to
Section 10(d) below) or (ii) the Fair Market Value of the Shares on the date on
which the purchase is to be effected if no consideration is paid pursuant to the
terms stated in the Transfer Notice, which Right of First Refusal shall be
exercised by written notice (the “First Refusal Exercise Notice”) to the Holder.
During the Option Period or the 45-day period specified in Section 10(f) below,
the Company may exercise its Repurchase Right (as set forth in Section 11 below)
in lieu of or in addition to its Right of First Refusal if the Repurchase Right
is or becomes exercisable during the Option Period or such 45-day period.

          (d) Payment Terms. The Company shall consummate the purchase of the
Offered Shares on the terms set forth in the Transfer Notice within 30 days
after delivery of the First Refusal Exercise Notice; provided, however, that in
the event the Transfer Notice provides for the payment for the Offered Shares
other than in cash, the Company and/or its assigns shall have the right to pay
for the Offered Shares by the discounted cash equivalent of the consideration
described in the Transfer Notice as reasonably determined by the Administrator.
Upon payment for the Offered Shares to the Holder or into escrow for the benefit
of the Holder, the Company or its assigns shall become the legal and beneficial
owner of the Offered Shares and all rights and interest therein or related
thereto, and the Company shall have the right to transfer the Offered Shares to
its own name or its assigns without further action by the Holder.

          (e) Assignment. Whenever the Company shall have the right to purchase
Shares under this Right of First Refusal, the Company may designate and assign
one or more employees, officers, directors or stockholders of the Company or
other persons or organizations, to exercise all or a part of the Company’s Right
of First Refusal.

          (f) Non-Exercise. If the Company and/or its assigns do not
collectively elect to exercise the Right of First Refusal within the Option
Period or such earlier time if the Company and/or its assigns notifies the
Holder that it will not exercise the Right of First Refusal, then the Holder may
transfer the Shares upon the terms and conditions stated in the Transfer Notice,
provided that:

5

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

 

  (i)   The transfer is made within forty-five (45) days of the earlier of
(A) the date the Company and/or its assigns notify the Holder that the Right of
First Refusal will not be exercised or (B) the expiration of the Option Period;
and     (ii)   The transferee agrees in writing that such Shares shall be held
subject to the provisions of this Option Agreement.

The Company shall have the right to demand further assurances from the Grantee
and the transferee (in a form satisfactory to the Company) that the transfer of
the Offered Shares was actually carried out on the terms and conditions
described in the Transfer Notice. No Offered Shares shall be transferred on the
books of the Company until the Company has received such assurances, if so
demanded, and has approved the proposed transfer as bona fide.

          (g) Expiration of Transfer Period. Following such 45-day period, no
transfer of the Offered Shares and no change in the terms of the transfer as
stated in the Transfer Notice (including the name of the proposed transferee)
shall be permitted without a new written Transfer Notice prepared and submitted
in accordance with the requirements of this Right of First Refusal.

          (h) Termination of Right of First Refusal. The provisions of this
Right of First Refusal shall terminate as to all Shares upon the Registration
Date.

          (i) Additional Shares or Substituted Securities. In the event of any
transaction described in Sections 10 or 11 of the Plan, any new, substituted or
additional securities or other property which is by reason of any such
transaction distributed with respect to the Shares shall be immediately subject
to the Right of First Refusal, but only to the extent the Shares are at the time
covered by such right.

     11. Company’s Repurchase Right.

          (a) Grant of Repurchase Right. The Company is hereby granted the right
to purchase all or any portion of the Shares (the “Repurchase Right”),
exercisable at any time (i) during the ninety (90) day period commencing on the
Termination Date, or (ii) during the ninety (90) day period commencing upon any
exercise of the Option that occurs after the Termination Date (together, the
“Share Repurchase Period”), provided, however, that if the Shares to be
repurchased are not Mature Shares then the Share Repurchase Period shall be
extended by the number of days necessary for the such Shares to become Mature
Shares. The Repurchase Right may only be exercised with respect to Mature
Shares.

          (b) Exercise of the Repurchase Right. The Repurchase Right shall be
exercisable by written notice delivered to each Holder of the Shares prior to
the expiration of the Share Repurchase Period. The notice shall indicate the
number of Shares to be repurchased and the date on which the repurchase is to be
effected, such date to be not later than the last day of the Share Repurchase
Period. On the date on which the repurchase is to be effected, the Company
and/or its assigns shall pay to the Holder in cash or cash equivalents
(including the cancellation of any purchase-money indebtedness) an amount equal
to (i) the Fair Market Value

6

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

 

on the date on which the repurchase is to be effected of the Shares which are to
be repurchased from the Holder, in the event of termination of the Grantee’s
Continuous Service other than for Cause, or (ii) the lesser of the Exercise
Price or the Fair Market Value on the date on which the repurchase is to be
effected of the Shares which are to be repurchased from the Holder, in the event
of termination of the Grantee’s Continuous Service for Cause. Upon such payment
or deposit into escrow for the benefit of the Holder, the Company and/or its
assigns shall become the legal and beneficial owner of the Shares being
repurchased and all rights and interest thereon or related thereto, and the
Company shall have the right to transfer to its own name or its assigns the
number of Shares being repurchased, without further action by the Holder.

          (c) Assignment. Whenever the Company shall have the right to purchase
Shares under this Repurchase Right, the Company may designate and assign one or
more employees, officers, directors or stockholders of the Company or other
persons or organizations, to exercise all or a part of the Company’s Repurchase
Right.

          (d) Termination of the Repurchase Right. The Repurchase Right shall
terminate with respect to any Shares for which it is not timely exercised. In
addition, the Repurchase Right shall terminate and cease to be exercisable with
respect to all Shares upon the Registration Date.

          (e) Additional Shares or Substituted Securities. In the event of any
transaction described in Sections 10 or 11 of the Plan, any new, substituted or
additional securities or other property which is by reason of any such
transaction distributed with respect to the Shares shall be immediately subject
to the Repurchase Right, but only to the extent the Shares are at the time
covered by such right.

     12. Stop-Transfer Notices. In order to ensure compliance with the
restrictions on transfer set forth in this Option Agreement, the Notice or the
Plan, the Company may issue appropriate “stop transfer” instructions to its
transfer agent, if any, and, if the Company transfers its own securities, it may
make appropriate notations to the same effect in its own records.

     13. Refusal to Transfer. The Company shall not be required (i) to transfer
on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Option Agreement or (ii) to treat as
owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so
transferred.

     14. Tax Consequences. Set forth below is a brief summary as of the date of
this Option Agreement of some of the federal tax consequences of exercise of the
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE GRANTEE SHOULD
CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES.

          (a) Exercise of Incentive Stock Option. If the Option qualifies as an
Incentive Stock Option, there will be no regular federal income tax liability
upon the exercise of the

7

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

 

Option, although the excess, if any, of the Fair Market Value of the Shares on
the date of exercise over the Exercise Price will be treated as income for
purposes of the alternative minimum tax for federal tax purposes and may subject
the Grantee to the alternative minimum tax in the year of exercise.

          (b) Exercise of Incentive Stock Option Following Disability. If the
Grantee’s Continuous Service terminates as a result of Disability that is not
permanent and total disability as such term is defined in Section 22(e)(3) of
the Code, to the extent permitted on the date of termination, the Grantee must
exercise an Incentive Stock Option within three (3) months of such termination
for the Incentive Stock Option to be qualified as an Incentive Stock Option.
Section 22(e)(3) of the Code provides that an individual is permanently and
totally disabled if he or she is unable to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment
which can be expected to result in death or which has lasted or can be expected
to last for a continuous period of not less than twelve (12) months.

          (c) Exercise of Non-Qualified Stock Option. On exercise of a
Non-Qualified Stock Option, the Grantee will be treated as having received
compensation income (taxable at ordinary income tax rates) equal to the excess,
if any, of the Fair Market Value of the Shares on the date of exercise over the
Exercise Price. If the Grantee is an Employee or a former Employee, the Company
will be required to withhold from the Grantee’s compensation or collect from the
Grantee and pay to the applicable taxing authorities an amount in cash equal to
a percentage of this compensation income at the time of exercise, and may refuse
to honor the exercise and refuse to deliver Shares if such withholding amounts
are not delivered at the time of exercise.

          (d) Disposition of Shares. In the case of a Non-Qualified Stock
Option, if Shares are held for more than one year, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. In the case of an Incentive Stock Option, if Shares
transferred pursuant to the Option are held for more than one year after receipt
of the Shares and are disposed more than two years after the Date of Award, any
gain realized on disposition of the Shares also will be treated as capital gain
for federal income tax purposes and subject to the same tax rates and holding
periods that apply to Shares acquired upon exercise of a Non-Qualified Stock
Option. If Shares purchased under an Incentive Stock Option are disposed of
prior to the expiration of such one-year or two-year periods, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the difference between the Exercise Price and the
lesser of (i) the Fair Market Value of the Shares on the date of exercise, or
(ii) the sale price of the Shares.

     15. Lock-Up Agreement.

          (a) Agreement. The Grantee, if requested by the Company and the lead
underwriter of any public offering of the Common Stock (the “Lead Underwriter”),
hereby irrevocably agrees not to sell, contract to sell, grant any option to
purchase, transfer the economic risk of ownership in, make any short sale of,
pledge or otherwise transfer or dispose of any interest in any Common Stock or
any securities convertible into or exchangeable or exercisable for or any other
rights to purchase or acquire Common Stock (except Common Stock included in

8

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

 

such public offering or acquired on the public market after such offering)
during the 200-day period following the effective date of a registration
statement of the Company filed under the Securities Act of 1933, as amended, or
such shorter or longer period of time as the Lead Underwriter shall specify. The
Grantee further agrees to sign such documents as may be requested by the Lead
Underwriter to effect the foregoing and agrees that the Company may impose
stop-transfer instructions with respect to such Common Stock subject to the
lock-up period until the end of such period. The Company and the Grantee
acknowledge that each Lead Underwriter of a public offering of the Company’s
stock, during the period of such offering and for the lock-up period thereafter,
is an intended beneficiary of this Section 15.

          (b) No Amendment Without Consent of Underwriter. During the period
from identification of a Lead Underwriter in connection with any public offering
of the Company’s Common Stock until the earlier of (i) the expiration of the
lock-up period specified in Section 15(a) in connection with such offering or
(ii) the abandonment of such offering by the Company and the Lead Underwriter,
the provisions of this Section 15 may not be amended or waived except with the
consent of the Lead Underwriter.

     16. Entire Agreement: Governing Law. The Notice, the Plan and this Option
Agreement constitute the entire agreement of the parties with respect to the
subject matter hereof and supersede in their entirety all prior undertakings and
agreements of the Company and the Grantee with respect to the subject matter
hereof, and may not be modified adversely to the Grantee’s interest except by
means of a writing signed by the Company and the Grantee. Nothing in the Notice,
the Plan and this Option Agreement (except as expressly provided therein) is
intended to confer any rights or remedies on any persons other than the parties.
The Notice, the Plan and this Option Agreement are to be construed in accordance
with and governed by the internal laws of the State of Nevada without giving
effect to any choice of law rule that would cause the application of the laws of
any jurisdiction other than the internal laws of the State of Nevada to the
rights and duties of the parties. Should any provision of the Notice, the Plan
or this Option Agreement be determined to be illegal or unenforceable, such
provision shall be enforced to the fullest extent allowed by law and the other
provisions shall nevertheless remain effective and shall remain enforceable.

     17. Construction. The captions used in the Notice and this Option Agreement
are inserted for convenience and shall not be deemed a part of the Option for
construction or interpretation. Except when otherwise indicated by the context,
the singular shall include the plural and the plural shall include the singular.
Use of the term “or” is not intended to be exclusive, unless the context clearly
requires otherwise.

     18. Administration and Interpretation. Any question or dispute regarding
the administration or interpretation of the Notice, the Plan or this Option
Agreement shall be submitted by the Grantee or by the Company to the
Administrator. The resolution of such question or dispute by the Administrator
shall be final and binding on all persons.

     19. Venue and Waiver of Jury Trial. The Company, the Grantee, and the
Grantee’s assignees pursuant to Section 8 (the “parties”) agree that any suit,
action, or proceeding arising out of or relating to the Notice, the Plan or this
Option Agreement shall be brought in the United

9

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

 

States District Court for the District of Nevada (or should such court lack
jurisdiction to hear such action, suit or proceeding, in a Nevada state court in
the County of Clark) and that the parties shall submit to the jurisdiction of
such court. The parties irrevocably waive, to the fullest extent permitted by
law, any objection the party may have to the laying of venue for any such suit,
action or proceeding brought in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY
RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR
PROCEEDING. If any one or more provisions of this Section 19 shall for any
reason be held invalid or unenforceable, it is the specific intent of the
parties that such provisions shall be modified to the minimum extent necessary
to make it or its application valid and enforceable.

     20. Notices. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery, upon
deposit for delivery by an internationally recognized express mail courier
service or upon deposit in the United States mail by certified mail (if the
parties are within the United States), with postage and fees prepaid, addressed
to the other party at its address as shown in these instruments, or to such
other address as such party may designate in writing from time to time to the
other party.

In connection with the purchase of the above-listed Securities, the undersigned
Grantee represents to the Company the following:

     (a) Grantee is aware of the Company’s business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Grantee is
acquiring these Securities for investment for Grantee’s own account only and not
with a view to, or for resale in connection with, any “distribution” thereof
within the meaning of the Securities Act of 1933, as amended (the “Securities
Act”).

     (b) Grantee acknowledges and understands that the Securities constitute
“restricted securities” under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon among other things, the bona fide nature of Grantee’s
investment intent as expressed herein. Grantee further understands that the
Securities must be held indefinitely unless they are subsequently registered
under the Securities Act or an exemption from such registration is available.
Grantee further acknowledges and understands that the Company is under no
obligation to register the Securities. Grantee understands that the certificate
evidencing the Securities will be imprinted with a legend which prohibits the
transfer of the Securities unless they are registered or such registration is
not required in the opinion of counsel satisfactory to the Company.

     (c) Grantee is familiar with the provisions of Rule 701 and Rule 144, each
promulgated under the Securities Act, which, in substance, permit limited public
resale of “restricted securities” acquired, directly or indirectly from the
issuer thereof, in a non-public offering subject to the satisfaction of certain
conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the
time of the grant of the Option to the Grantee, the exercise will be exempt from
registration under the Securities Act. In the event the Company becomes subject
to the reporting requirements of Section 13 or 15(d) of the Securities Exchange
Act of 1934, ninety (90) days thereafter (or such longer period as any market
stand-off agreement may require) the Securities exempt under Rule 701 may be
resold, subject to the satisfaction of certain of the conditions specified by
Rule 144, including: (1) the resale being made through a broker in an
unsolicited “broker’s transaction” or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934); and,
in the case of an affiliate, (2) the availability of certain public information
about the Company, (3) the amount of Securities being

sold during any three month period not exceeding the limitations specified in
Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two (2) years, the satisfaction of the conditions set forth
in sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d) Grantee further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Grantee understands that no assurances can be given that any
such other registration exemption will be available in such event.

     (e) Grantee represents that Grantee is a resident of the state of ______.
