AmendmentToImpulse! Buy Network, Inc. 1997 Stock Plan

The Impulse Buy Network, Inc. 1997 Stock Plan is hereby amended effective March 29, 2000 as follows (the Plan):

A.  Section 2 is amended by adding the following definitions:

Cause means (i) any act of personal dishonesty taken by the Optionee in connection with his responsibilities as an employee and intended to result in substantial personal enrichment of the Optionee, (ii) the
conviction of a felony, (iii) a willful act by the Optionee that constitutes gross misconduct and that is injurious to the Company, (iv) for a period of not less than thirty (30) days following delivery to the Optionee of a written demand for performance
from the Company that describes the basis for the Companys belief that the Optionee has not substantially performed his duties, continued violations by the Optionee of the Optionees obligations to the Company that are demonstrably willful and
deliberate on the Optionees part or (v) as otherwise provided in an option agreement.

Change of Control means the occurrence of any of the following:

(i)  Any person (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended)
becomes the beneficial owner (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the total voting power represented by the Companys then
outstanding voting securities entitled to vote generally in the election of directors;

(ii)  Any action or event occurring within a two-year period, as a result of which fewer than a majority of the directors are
Incumbent Directors. Incumbent Directors shall mean directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for election, to the Board with the affirmative votes of at least a majority of
the Incumbent Directors at the time of such election or nomination (but shall not include an individual whose election or nomination is in connection with an actual or threatened proxy contest relating to the election of directors to the Company);

(iii)  The consummation of a merger or consolidation of the Company with any other corporation, other than a merger or consolidation
which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or the entity that controls such
surviving entity) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company, such surviving entity or entity that controls such surviving entity outstanding immediately after such merger or consolidation; or

(iv)   The consummation of the sale or disposition by the Company of all or substantially all of the Companys assets.

B.  Section 9(b) is amended by deleting the previous Section 9(b) and replacing it in its entirety as follows:

9(b)  Termination of Employment or Consulting Relationship. Notwithstanding the exercise periods set forth in the Stock Option
Agreement, exercise of an Option shall always be subject to the following:

| |  | If the Optionee is Terminated for any reason except death or Disability, then Optionee may exercise such Optionees Options only to the extent that such Options would have been exercisable upon the Termination Date no
later than three (3) months after the Termination Date (or such shorter time period as may be specified in the Stock Option Agreement), but in any event, no later than the expiration date of the Options. Notwithstanding the foregoing, if the Company or
any successor thereto terminates the Optionees employment without Cause within twelve months following a Change of Control, the Optionees Options, and restricted stock acquired upon exercise of the Optionees Options or otherwise granted
under the Plan shall become 100% vested and exercisable; provided, however, that no such acceleration shall occur in the event that it would preclude accounting for any business combination of the Company involving a Change of Control as a pooling

Unless the Company and the Optionee otherwise agree in writing, any determination required under this Section shall be made in writing by the Companys independent public accountants (the 
Accountants), whose determination shall be conclusive and binding upon the Optionee and the Company for all purposes. For purposes of making the calculations required by this Section, the Accountants may make reasonable assumptions and
approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Optionee shall furnish to the Accountants such information and
documents as the Accountants may reasonably request in order to make a determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section.
