exercised for less than 100 Shares unless the exercise is the full exercise of

SECTION 4. NO TRANSFER OR ASSIGNMENT OF OPTION.

Except as otherwise provided in this Agreement with respect to NQSOs only, this

sold, pledged or otherwise transferred (whether by operation of law or
otherwise) and are not subject to sale under execution, attachment, levy or
similar process. The terms of the Plan and this Agreement are binding upon the
executors, administrators, heirs, successors and assigns of the Optionee.

SECTION 5. EXERCISE PROCEDURES.

(a) Notice of Exercise. The Optionee or the Optionee’s representative may
exercise this option by giving written notice to the Company in a form
acceptable to the Company. The notice must specify the election to exercise this
option, the number of Shares for which it is being exercised and the form and
amount of payment. The notice must be signed by the person exercising this
option. If this option is exercised by the representative of the Optionee, the
notice must be accompanied by proof (satisfactory to the Company) of the
representative’s right to exercise this option. The Optionee or the Optionee’s
representative must deliver to the Company, at the time of giving the notice,
payment in a form permissible under Section 6 for the full amount of the
Purchase Price.

(b) Issuance of Shares. After receiving a proper notice of exercise and payment
for the Shares, the Company will issue a certificate or certificates for the
Shares as to which this option has been exercised.

(c) Withholding Taxes. If the Company determines that it is required to withhold
any tax as a result of the exercise of this option, the Optionee, as a condition
to the exercise of this option, must make arrangements satisfactory to the
Company to enable it to satisfy all withholding requirements. The Optionee must

withholding requirements that may arise in connection with the vesting or
disposition of Shares purchased by exercising this option.

SECTION 6. PAYMENT FOR STOCK.

(a) Cash. All or part of the Purchase Price may be paid in cash or cash
equivalents.

(b) Surrender of Stock. All or any part of the Purchase Price may be paid by
surrendering, or attesting to the ownership of, Shares that are already owned by
the Optionee. Those Shares must be surrendered to the Company in good form for
transfer and will be valued at their Fair Market Value on the date when this
option is exercised. The Optionee may not surrender, or attest to the ownership
of, Shares in payment of the Purchase Price if that action would cause the
Company to recognize compensation expense (or additional compensation expense)
with respect to this option for financial reporting purposes.

(c) Exercise/Sale or Exercise/Pledge. If and to the extent permitted by law and
approved by the Committee, in the event that generally accepted accounting
principles require

 

4

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

the Company to record the grant of options as an expense, and if the Stock is
publicly traded, all or part of the Purchase Price and any withholding taxes may
be paid as follows:

(i) by the delivery (on a form prescribed by the Company) of an irrevocable
direction to a securities broker approved by the Company to sell Shares and to
deliver all or part of the sales proceeds to the Company; or

(ii) by the delivery (on a form prescribed by the Company) of an irrevocable
direction to pledge Shares to a securities broker or lender approved by the
Company, as security for a loan, and to deliver all or part of the loan proceeds
to the Company.

SECTION 7. TERM AND EXPIRATION.

(a) Basic Term. This option will expire on the date that is 10 years after the
Date of Grant (five years after the Date of Grant if this option is designated
as an ISO in this Agreement and Section 4(b) of the Plan applies).

(b) Termination of Service. If the Optionee’s Service terminates then this
option will expire in accordance with the provisions contained in the Plan.

(c) Notice Concerning ISO Treatment. If this option is designated as an ISO in
this Agreement, it ceases to qualify for favorable tax treatment as an ISO to
the extent it is exercised after the Optionee has been on a leave of absence for
more than 90 days, unless the Optionee’s reemployment rights are guaranteed by
statute or by contract.

SECTION 8. LEGALITY OF INITIAL ISSUANCE.

No Shares will be issued upon the exercise of this option unless and until the
Company has determined that:

(a) It and the Optionee have taken any actions required to register the Shares
under the Securities Act or to perfect an exemption from the registration
requirements thereof,

(b) Any applicable listing requirement of any stock exchange or other securities
market on which Stock is listed has been satisfied;

(c) The Plan has been approved by the Company’s stockholders; and

(d) Any other applicable provision of state or federal law has been satisfied.

SECTION 9. NO REGISTRATION RIGHTS.

The Company may, but is not obligated to, register or qualify the sale of Shares
under the Securities Act or any other applicable law. The Company is not
obligated to take any affirmative action to cause the sale of Shares under this
Agreement to comply with any law.

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

SECTION 10. RESTRICTIONS ON TRANSFER.

(a) Securities Law Restrictions. Regardless of whether the offering and sale of
Shares under this Agreement have been registered under the Securities Act or
have been registered or qualified under the securities laws of any state, the
Company at its discretion may impose restrictions on the sale, pledge or other
transfer of the Shares (including the placement of appropriate legends on stock
certificates or the imposition of stop-transfer instructions) if, in the
judgment of the Company, those restrictions are necessary or desirable to
achieve compliance with the Securities Act, the securities laws of any state or
any other law. Any determination by the Company and its counsel in connection
with any of the matters set forth in this Section 10 is conclusive and binding
on the Optionee and all other persons.

(b) Investment Intent at Agreement. The Optionee represents and agrees that the
Shares to be acquired upon exercising this option will be acquired for
investment, and not with a view to the sale or distribution thereof.

(c) Investment Intent at Exercise. If the sale of Shares under this Agreement is
not registered under the Securities Act but an exemption is available that
requires an investment representation or other representation, the Optionee will
represent and agree at the time of exercise that the Shares being acquired upon
exercising this option are being acquired for investment, and not with a view to
their sale or distribution, and will make any other representations that are
deemed necessary or appropriate by the Company and its counsel.

(d) Legends. All certificates evidencing Shares purchased under this Agreement
in an unregistered transaction will bear the following legend (and such other
restrictive legends as are required or deemed advisable under the provisions of
any applicable law):

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED
WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR AN OPINION OF
COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS
NOT REQUIRED.

(e) Removal of Legends. If, in the opinion of the Company and its counsel, any
legend placed on a stock certificate representing Shares sold under this
agreement is no longer required, the holder of the certificate will be entitled
to exchange the certificate for a certificate representing the same number of
Shares but without the legend.

(f) Administration. Any good faith determination by the Company and its counsel
in connection with any of the matters set forth in this Section 10 is conclusive
and binding on the Optionee and all other persons.

SECTION 11. CHANGE OF CONTROL.

Notwithstanding Section 6(g) of the Plan, the exercisability of the option
granted pursuant to this Agreement shall not accelerate as a result of a Change
in Control.

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

SECTION 12. ADJUSTMENT OF SHARES.

In the event of any transaction described in Section 8(a) of the Plan, the terms
of this option (including, without limitation, the number and kind of Shares
subject to this option and the Exercise Price) will be adjusted or exchanged as
set forth in Section 8(a) of the Plan. In the event that the Company is a party
to a merger, consolidation or other reorganization, this option will be subject
to the agreement of merger, consolidation or other reorganization, as provided
in Section 8(b) of the Plan.

SECTION 13. MISCELLANEOUS PROVISIONS.

(a) Income Tax Consequences. The Optionee acknowledges that the Company has
advised him or her that there are income tax consequences related to the
purchase of Shares by the Optionee and that the Company has recommended that he
or she obtain independent advice on the tax consequences of the purchase of the
Shares. The Optionee hereby releases and discharges the Company and its
affiliates, directors, officers and agents from any and all responsibility or
liability with respect to any tax consequences to the Optionee of his or her
purchase or sale of the Shares of the Company purchased by the Optionee under
the Plan or otherwise.

(b) Rights as a Shareholder. Neither the Optionee nor the Optionee’s
representative has any rights as a shareholder with respect to any Shares
subject to this option prior to the date of issuance to the Optionee or the
Optionee’s representative of a certificate or certificates for the Shares.

(c) No Retention Rights. Nothing in this Agreement or in the Plan confers upon
the Optionee any right to continue in Service for any period of time or
interferes with or otherwise restricts in any way the rights of the Company (or
any Subsidiary) or of the Optionee, which rights are hereby expressly reserved
by each, to terminate his or her Service at any time and for any reason.

(d) Notice. Any notice required by the terms of this Agreement must be given in
writing and will be deemed effective upon personal delivery, upon deposit (with
fees prepaid) with nationally recognized overnight delivery service, or on the
fifth business day following deposit (with first class postage and fees prepaid)
with the United States Postal Service. Notice must be addressed to the Company
at its principal executive office and to the Optionee at the address that he or
she most recently provided to the Company.

(e) Entire Agreement. This Agreement and the Plan constitute the entire contract
between the parties hereto with regard to the grant and exercise of the option.
They supersede any other agreements, representations or understandings (whether
oral or written and whether express or implied) that relate to the option.

(f) Choice of Law. This Agreement is governed by, and construed in accordance
with, the laws in force in the State of Nevada.
