 TERMS AND CONDITIONS TO THE 

INCENTIVE STOCK OPTION GRANTED 
 PURSUANT TO THE

 SFA, INC. 2007 STOCK OPTION PLAN 

1. Exercise of Option. Subject to the provisions provided herein or in the Award made pursuant to the SFA, Inc. 2007 Stock Option Plan: 

(a) The Option may be exercised with respect to all or any portion of the vested Option Shares at any time during the Option Period by the delivery to
the Company, at its principal place of business, of (i) a written notice of exercise in substantially the form attached hereto as Exhibit 1, which shall be actually delivered to the Company within the time required by the administrator and
(ii) payment to the Company of the Exercise Price multiplied by the number of shares being purchased (the “Purchase Price”) in the manner provided in Subsection (b). 

(b) The Purchase Price shall be paid in full upon the exercise of an Option and no Option Shares shall be issued or delivered until full payment therefor
has been made. Payment of the Purchase Price for all Option Shares purchased pursuant to the exercise of an Option shall be made in cash, certified check, or, alternatively, as follows: 

(i) by delivery to the Company of a number of shares of Common Stock which have been owned by Optionee for at least six (6) months prior to the date
of the Option’s exercise, have a Fair Market Value, as determined under the Plan, on the date of exercise either equal to the Purchase Price or in combination with cash to equal the Purchase Price; or 

(ii) by receipt of the Purchase Price in cash from a broker, dealer or other “creditor” as defined by Regulation T issued by the Board of
Governors of the Federal Reserve System following delivery by the Optionee to the Committee (defined in the Plan) of instructions in a form acceptable to the Committee regarding delivery to such broker, dealer or other creditor of that number of
Option Shares with respect to which the Option is exercised. 
 Upon acceptance of such notice and receipt of payment in full of the Purchase
Price and any tax withholding liability, to the extent applicable, Company shall cause to be issued a certificate representing the Option Shares purchased. 

2. Withholding. The Optionee must satisfy federal, state and local, if any, withholding taxes imposed by reason of the exercise of the Option either by
paying to the Company the full amount of the required statutory withholding obligation (i) in cash; (ii) by electing, irrevocably and in writing (the “Withholding Election”), to have the smallest number of whole shares of Common
Stock which, when multiplied by the Fair Market Value of the Common Stock as of the date the Option is exercised, is sufficient to satisfy the minimum required amount of withholding tax; or (iii) by a combination of the above. Optionee may make
a Withholding Election only if both of the following conditions are met: 
 (a) the Withholding Election is made on or prior to the date on
which the amount of tax required to be withheld is determined (the “Tax Date”) by executing and delivering to the Company a properly completed Notice of Withholding Election in substantially the form attached hereto as Exhibit 2; and

  

 3 








 (b) any Withholding Election will be irrevocable; however, the Committee (defined in the Plan) may, in its
sole discretion, disapprove and give no effect to the Withholding Election. 
 3. Rights as Shareholder. Until the stock certificates reflecting
the Option Shares accruing to the Optionee upon exercise of the Option are issued to the Optionee, the Optionee shall have no rights as a shareholder with respect to such Option Shares. The Company shall make no adjustment for any dividends or
distributions or other rights on or with respect to Option Shares for which the record date is prior to the issuance of that stock certificate, except as the Plan or this Award otherwise provides. In connection with the exercise of the Option, and
as a condition thereto, the Optionee shall be required to execute a counterpart signature page to that certain Stockholders Agreement, dated as of February     , 2007, by and among Global Technology Strategies, Inc., the
Company and the other stockholders party thereto.

nontransferable other than by will or the laws of descent and distribution, and, shall be exercisable during the lifetime of the Optionee only by the Optionee (or in the event of his Disability, by his legal representative) and after his death, only
by legal representative of the Optionee’s estate. 
 5. Changes in Capitalization. 

(a) The number of Option Shares and the Exercise Price shall be proportionately adjusted for any increase or decrease in the number of issued shares of
Common Stock resulting from a subdivision or combination of shares or the payment of a stock dividend in shares of Common Stock to holders of outstanding shares of Common Stock or any other increase or decrease in the number of shares of Common
Stock outstanding effected without receipt of consideration by the Company. 
 (b) If the Company shall be the surviving corporation in any
merger or consolidation, extraordinary dividend (including a spin-off), reorganization, Change in Control, or other change in the corporate structure of the Company or its Common Stock or tender offer for shares of Common Stock, the Committee may,
in its sole discretion, adjust the number and class of securities subject to the new Option, with a corresponding adjustment made in the Exercise Price; substitute a new option to replace the Option; terminate or accelerate the Option Period; or
terminate the Option in consideration of the payment to Optionee of the excess of the then Fair Market Value (as defined in the Plan) of the vested Option Shares over the aggregate Exercise Price of the vested Option Shares. 

(c) The existence of the Plan and this Award shall not affect in any way the right or power of the Company to make or authorize any adjustment,
reclassification, reorganization or other change in its capital or business structure, any merger or consolidation of the Company, any issue of debt or equity securities having preferences or priorities as to the Common Stock or the rights thereof,
the dissolution or liquidation of the Company, any sale or transfer of all or any part of its business or assets, or any other corporate act or proceeding.

time the Committee, in its discretion, shall determine that the listing, registration or qualification of the shares covered by the Option upon any securities exchange or under any state or federal law is necessary or desirable as a condition of or
in connection with the delivery of shares thereunder, the delivery of any or all shares pursuant to the Option may be withheld unless and until such listing, registration or qualification shall have been effected. The Optionee shall deliver to the
Company, prior to the exercise of the Option, such information, representations and warranties as the Company may reasonably request in order for the Company to be able to satisfy itself that the Option Shares being acquired in accordance with the
