The Board of Directors (the "Board" which term shall include an authorized committee of the Board of Directors) and shareholders of the Company have heretofore adopted a 2009 Incentive Stock Plan (the "Plan"), pursuant to which this Option is being granted.

(c)

The Board has authorized the granting to Optionee of an incentive stock option ("Option") as defined in Section 422 of the Internal Revenue Code of 1986, as amended, (the "Code") to purchase shares of common stock of the Company ("Stock") upon the terms and conditions hereinafter stated and pursuant to an exemption from registration under the Securities Act of 1933, as amended (the "Securities Act") provided by Section 4(2) thereunder.

3.  Shares; Price.  The Company hereby grants to Optionee the right to purchase, upon and subject to the terms and conditions herein stated, the number of shares of Stock set forth in Section 1(c) above (the "Shares") for cash (or other consideration as is authorized under the Plan and acceptable to the Board, in their sole and absolute discretion) at the price per Share set forth in Section 1(d) above (the "Exercise Price"), such price being not less than the fair market value per share of the Shares covered by this Option as of the date hereof (unless Optionee is the owner of Stock possessing ten percent or more of the total voting power or value of all outstanding Stock of the Company, in which case the Exercise Price shall be no less than 110% of the fair market value of such Stock).

4.  Term of Option; Continuation of Employment.  This Option shall expire, and all rights hereunder to purchase the Shares shall terminate [__] (___) years from the date hereof. This Option shall earlier terminate subject to Sections 7 and 8 hereof upon, and as of the date of, the termination of Optionee's employment if such termination occurs prior to the end of such [__] (___) year period. Nothing contained herein shall confer upon Optionee the right to the continuation of his or her employment by the Company or to interfere with the right of the Company to terminate such employment or to increase or decrease the compensation of Optionee from the rate in existence at the date hereof.

5.  Vesting of Option. Subject to the provisions of Sections 7 and 8 hereof, this Option shall become exercisable during the term of Optionee's employment in [__] (___) equal annual installments of [___] percent ([__]%) of the Shares covered by this Option, the first installment to be exercisable on the [__] (___) month anniversary of the date of this Option (the "Initial Vesting Date"), with an additional [____] percent ([__]%) of such Shares becoming

SLC_455207.1

exercisable on each of the successive [__] (___) month periods following the Initial Vesting Date. The installments shall be cumulative (i.e., this option may be exercised, as to any or all Shares covered by an installment, at any time or times after an installment becomes exercisable and until expiration or termination of this option). 

6.  Exercise.  This Option shall be exercised as follows:

(i)  

by delivery to the Company of (a) written notice of exercise stating the number of Shares being purchased (in whole shares only) and such other information set forth on the form of Notice of Exercise attached hereto as Appendix A, (b) a check or cash in the amount of the Exercise Price of the Shares covered by the notice (or such other consideration as has been approved by the Board of Directors consistent with the Plan) and (c) a written investment representation as provided for in Section 13 hereof, or

(ii)  

through a special sale and remittance procedure pursuant to which the Optionee shall concurrently provide irrevocable written instructions (a) to a Company designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes required to be withheld by the Company by reason of such purchase and (b) to the Company to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale transaction; or  

(iii)

through a cashless exercise approved by the Company in compliance with Section 402 of the Sarbanes Oxley Act in which the Optionee shall surrender the Option to the Company, and the Company shall issue the Optionee the number of shares determined as follows:

X = Y (A-B) /A where:

X = the number of shares to be issued to the Optionee.

Y = the number of shares with respect to which the Option is being exercised.

A = the closing sale price of the Common Stock on the date of exercise, or in the absence thereof, the fair market value on the date of exercise, and

B = the option exercise price.

This Option shall not be assignable or transferable, except by will or by the laws of descent and distribution, and shall be exercisable only by Optionee during his or her lifetime, except as provided in Section 8 hereof.

7.  Termination of Employment.  If Optionee shall cease to be employed by the Company for any reason, whether voluntarily or involuntarily, other than by his or her death, Optionee (or if the Optionee shall die after such termination, but prior to such exercise date, Optionee's personal representative or the person entitled to succeed to the Option) shall have the right at any time within three (3) months following such termination of employment or the remaining term of this Option, whichever is the lesser, to exercise in whole or in part this Option to the extent, but only to the extent, that this Option was exercisable as of the date of termination of employment and had not previously been exercised; provided, however: (i) if Optionee is permanently disabled (within the meaning of Section 22(e)(3) of the Code) at the time of termination, the foregoing three (3) month period shall be extended to six (6) months; or (ii) if Optionee is terminated "for cause," as that term is defined by the terms of the Plan or this Option Agreement or by any employment agreement between the Optionee and the Company, this Option shall automatically terminate as to all Shares covered by this Option not exercised prior to termination. Unless earlier terminated, all rights under this Option shall terminate in any event on the expiration date of this Option as defined in Section 4 hereof.

8.  Death of Optionee.  If the Optionee shall die while in the employ of the Company, Optionee's personal representative or the person entitled to Optionee's rights hereunder may at any time within six (6) months after the date of Optionee's death, or during the remaining term of this Option, whichever is the lesser, exercise this Option

2

SLC_455207.1

and purchase Shares to the extent, but only to the extent, that Optionee could have exercised this Option as of the date of Optionee's death; provided, in any case, that this Option may be so exercised only to the extent that this Option has not previously been exercised by Optionee.

9.  No Rights as Shareholder.  Optionee shall have no rights as a shareholder with respect to the Shares covered by any installment of this Option until the effective date of issuance of Shares following exercise of this Option, and no adjustment will be made for dividends or other rights for which the record date is prior to the date such stock certificate or certificates are issued except as provided in Section 10 hereof.

10.  Recapitalization.  Subject to any required action by the shareholders of the Company, the number of Shares covered by this Option, and the Exercise Price thereof, shall be proportionately adjusted for any increase or decrease in the number of issued shares resulting from a subdivision or consolidation of shares or the payment of a stock dividend, or any other increase or decrease in the number of such shares effected without receipt of consideration by the Company; provided however that the conversion of any convertible securities of the Company shall not be deemed having been "effected without receipt of consideration by the Company".

In the event of a proposed dissolution or liquidation of the Company, a merger or consolidation in which the Company is not the surviving entity, or a sale of all or substantially all of the assets or capital stock of the Company (collectively, a "Reorganization"), unless otherwise provided by the Board, this Option shall terminate immediately prior to such date as is determined by the Board, which date shall be no later than the consummation of such Reorganization. In such event, if the entity which shall be the surviving entity does not tender to Optionee an offer, for which it has no obligation to do so, to substitute for any unexercised Option a stock option or capital stock of such surviving of such surviving entity, as applicable, which on an equitable basis shall provide the Optionee with substantially the same economic benefit as such unexercised Option, then the Board may grant to such Optionee, in its sole and absolute discretion and without obligation, the right for a period commencing thirty (30) days prior to and ending immediately prior to the date determined by the Board pursuant hereto for termination of the Option or during the remaining term of the Option, whichever is the lesser, to exercise any unexpired Option or Options without regard to the installment provisions of Section 5; provided, however, that such exercise shall be subject to the consummation of such Reorganization.

Subject to any required action by the shareholders of the Company, if the Company shall be the surviving entity in any merger or consolidation, this Option thereafter shall pertain to and apply to the securities to which a holder of Shares equal to the Shares subject to this Option would have been entitled by reason of such merger or consolidation, and the installment provisions of Section 5 shall continue to apply.

In the event of a change in the shares of the Company as presently constituted, which is limited to a change of all of its authorized Stock without par value into the same number of shares of Stock with a par value, the shares resulting from any such change shall be deemed to be the Shares within the meaning of this Option.

To the extent that the foregoing adjustments relate to shares or securities of the Company, such adjustments shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as hereinbefore expressly provided, Optionee shall have no rights by reason of any subdivision or consolidation of shares of Stock of any class or the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class, and the number and price of Shares subject to this Option shall not be affected by, and no adjustments shall be made by reason of, any dissolution, liquidation, merger, consolidation or sale of assets or capital stock, or any issue by the Company of shares of stock of any class or securities convertible into shares of stock of any class.

The grant of this Option shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes in its capital or business structure or to merge, consolidate, dissolve or liquidate or to sell or transfer all or any part of its business or assets.

11.  Additional Consideration.  Should the Internal Revenue Service determine that the Exercise Price established by the Board as the fair market value per Share is less than the fair market value per Share as of the date of Option grant, Optionee hereby agrees to tender such additional consideration, or agrees to tender upon exercise of all or a portion of this Option, such fair market value per Share as is determined by the Internal Revenue Service.

SLC_455207.1

12. Modifications, Extension and Renewal of Options.  The Board or Committee, as described in the Plan, may modify, extend or renew this Option or accept the surrender thereof (to the extent not theretofore exercised) and authorize the granting of a new option in substitution therefor (to the extent not theretofore exercised), subject at all times to the Plan, and Section 422 of the Code. Notwithstanding the foregoing provisions of this Section 12, no modification shall, without the consent of the Optionee, alter to the Optionee's detriment or impair any rights of Optionee hereunder.

13.  Investment Intent; Restrictions on Transfer.

  (a)

Optionee represents and agrees that if Optionee exercises this Option in whole or in part, Optionee will in each case acquire the Shares upon such exercise for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof; and that upon such exercise of this Option in whole or in part, Optionee (or any person or persons entitled to exercise this Option under the provisions of Sections 7 and 8 hereof) shall furnish to the Company a written statement to such effect, satisfactory to the Company in form and substance. If the Shares represented by this Option are registered under the Securities Act, either before or after the exercise of this Option in whole or in part, the Optionee shall be relieved of the foregoing investment representation and agreement and shall not be required to furnish the Company with the foregoing written statement.

(b)

Optionee further represents that Optionee has had access to the financial statements or books and records of the Company, has had the opportunity to ask questions of the Company concerning its business, operations and financial condition, and to obtain additional information reasonably necessary to verify the accuracy of such information.

(c)

Unless and until the Shares represented by this Option are registered under the Securities Act, all certificates representing the Shares and any certificates subsequently issued in substitution therefor and any certificate for any securities issued pursuant to any stock split, share reclassification, stock dividend or other similar capital event shall bear legends in substantially the following form:

THESE SECURITIES HAVE NOT BEEN REGISTERED OR OTHERWISE QUALIFIED UNDER THE SECURITIES ACT OF 1933 (THE 'SECURITIES ACT') OR UNDER THE APPLICABLE OR SECURITIES LAWS OF ANY STATE. NEITHER THESE SECURITIES NOR ANY INTEREST THEREIN MAY BE SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE SECURITIES LAWS OF ANY STATE, UNLESS PURSUANT TO EXEMPTIONS THEREFROM.

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED PURSUANT TO THAT CERTAIN INCENTIVE STOCK OPTION AGREEMENT DATED ____________ BETWEEN THE COMPANY AND THE ISSUEE WHICH RESTRICTS THE TRANSFER OF THESE SHARES WHICH ARE SUBJECT TO REPURCHASE BY THE COMPANY UNDER CERTAIN CONDITIONS.

or such other legend or legends as the Company and its counsel deem necessary or appropriate. Appropriate stop transfer instructions with respect to the Shares have been placed with the Company's transfer agent.

14.  Effects of Early Disposition.  Optionee understands that if an Optionee disposes of shares acquired hereunder within two (2) years after the date of this Option or within one (1) year after the date of issuance of such shares to Optionee, such Optionee will be treated for income tax purposes as having received ordinary income at the time of such disposition of an amount generally measured by the difference between the purchase price and the fair market value of such stock on the date of exercise, subject to adjustment for any tax previously paid, in addition to any tax on the difference between the sales price and Optionee's adjusted cost basis in such shares. The foregoing amount may be measured differently if Optionee is an officer, director or ten percent holder of the Company. Optionee agrees to notify the Company within ten (10) working days of any such disposition.

4

SLC_455207.1

15.  Stand-off Agreement.  Optionee agrees that in connection with any registration of the Company's securities under the Securities Act, and upon the request of the Company or any underwriter managing an underwritten offering of the Company's securities, Optionee shall not sell, short any sale of, loan, grant an option for, or otherwise dispose of any of the Shares (other than Shares included in the offering) without the prior written consent of the Company or such managing underwriter, as applicable, for a period of at least one year following the effective date of registration of such offering.

16.  Restriction upon Transfer.  The Shares may not be sold, transferred or otherwise disposed of and shall not be pledged or otherwise hypothecated by the Optionee except as hereinafter provided.

(a)

Repurchase Right on Termination Other Than for Cause. For the purposes of this Section, a "Repurchase Event" shall mean an occurrence of one of (i) termination of Optionee's employment by the Company, voluntary or involuntary and with or without cause; (ii) retirement or death of Optionee; (iii) bankruptcy of Optionee, which shall be deemed to have occurred as of the date on which a voluntary or involuntary petition in bankruptcy is filed with a court of competent jurisdiction; (iv) dissolution of the marriage of Optionee, to the extent that any of the Shares are allocated as the sole and separate property of Optionee's spouse pursuant thereto (in which case this Section shall only apply to the Shares so affected); or (v) any attempted transfer by the Optionee of Shares, or any interest therein, in violation of this Agreement. Upon the occurrence of a Repurchase Event, the Company shall have the right (but not an obligation) to repurchase all or any portion of the Shares of Optionee at a price equal to the fair value of the Shares as of the date of the Repurchase Event.

(b)

Repurchase Right on Termination for Cause.  In the event Optionee's employment is terminated by the Company "for cause", then the Company shall have the right (but not an obligation) to repurchase Shares of Optionee at a price equal to the Exercise Price. Such right of the Company to repurchase Shares shall apply to 100% of the Shares for one (1) year from the date of this Agreement; and shall thereafter lapse at the rate of twenty percent (20%) of the Shares on each anniversary of the date of this Agreement. In addition, the Company shall have the right, in the sole discretion of the Board and without obligation, to repurchase upon termination for cause all or any portion of the Shares of Optionee, at a price equal to the fair value of the Shares as of the date of termination, which right is not subject to the foregoing lapsing of rights. In the event the Company elects to repurchase the Shares, the stock certificates representing the same shall forthwith be returned to the Company for cancellation.

(c)

Exercise of Repurchase Right.  Any Repurchase Right under Paragraphs 16(a) or 16(b) shall be exercised by giving notice of exercise as provided herein to Optionee or the estate of Optionee, as applicable. Such right shall be exercised, and the repurchase price thereunder shall be paid, by the Company within a ninety (90) day period beginning on the date of notice to the Company of the occurrence of such Repurchase Event (except in the case of termination of employment or retirement, where such option period shall begin upon the occurrence of the Repurchase Event). Such repurchase price shall be payable only in the form of cash (including a check drafted on immediately available funds) or cancellation of purchase money indebtedness of the Optionee for the Shares. If the Company can not purchase all such Shares because it is unable to meet the financial tests set forth in Nevada and/or Nevada corporation law, the Company shall have the right to purchase as many Shares as it is permitted to purchase under such sections. Any Shares not purchased by the Company hereunder shall no longer be subject to the provisions of this Section 16.

(d)

Right of First Refusal.  In the event Optionee desires to transfer any Shares during his or her lifetime, Optionee shall first offer to sell such Shares to the Company. Optionee shall deliver to the Company written notice of the intended sale, such notice to specify the number of Shares to be sold, the proposed purchase price and terms of payment, and grant the Company an option for a period of thirty days following receipt of such notice to purchase the offered Shares upon the same terms and conditions. To exercise such option, the Company shall give notice of that fact to Optionee within the thirty (30) day notice period and agree to pay the purchase price in the manner provided in the

5

SLC_455207.1

notice. If the Company does not purchase all of the Shares so offered during foregoing option period, Optionee shall be under no obligation to sell any of the offered Shares to the Company, but may dispose of such Shares in any lawful manner during a period of one hundred and eighty (180) days following the end of such notice period, except that Optionee shall not sell any such Shares to any other person at a lower price or upon more favorable terms than those offered to the Company.

(e)

Acceptance of Restrictions.  Acceptance of the Shares shall constitute the Optionee's agreement to such restrictions and the legending of his certificates with respect thereto. Notwithstanding such restrictions, however, so long as the Optionee is the holder of the Shares, or any portion thereof, he shall be entitled to receive all dividends declared on and to vote the Shares and to all other rights of a shareholder with respect thereto.

(f)

Permitted Transfers.  Notwithstanding any provisions in this Section 16 to the contrary, the Optionee may transfer Shares subject to this Agreement to his or her parents, spouse, children, or grandchildren, or a trust for the benefit of the Optionee or any such transferee(s); provided, that such permitted transferee(s) shall hold the Shares subject to all the provisions of this Agreement (all references to the Optionee herein shall in such cases refer mutatis mutandis to the permitted transferee, except in the case of clause (iv) of Section 16(a) wherein the permitted transfer shall be deemed to be rescinded); and provided further, that notwithstanding any other provisions in this Agreement, a permitted transferee may not, in turn, make permitted transfers without the written consent of the Optionee and the Company.

(g)

Release of Restrictions on Shares.  All rights and restrictions under this Section 16 shall terminate [__] (___) years following the date of this Agreement, or when the Company's securities are publicly traded, whichever occurs earlier.

17.  Notices.  Any notice required to be given pursuant to this Option or the Plan shall be in writing and shall be deemed to be delivered upon receipt or, in the case of notices by the Company, five (5) days after deposit in the U.S. mail, postage prepaid, addressed to Optionee at the address last provided to the Company by Optionee for his or her employee records.

18.  Agreement Subject to Plan; Applicable Law.  This Option is made pursuant to the Plan and shall be interpreted to comply therewith. A copy of such Plan is available to Optionee, at no charge, at the principal office of the Company. Any provision of this Option inconsistent with the Plan shall be considered void and replaced with the applicable provision of the Plan. This Option has been granted, executed and delivered in the State of Nevada, and the interpretation and enforcement shall be governed by the laws thereof and subject to the exclusive jurisdiction of the courts therein.
