in writing), to purchase from the Company up to 625,000 fully paid and nonassessable shares of the Common Stock of the Company, as more fully described below. The number of shares of Common Stock
issuable pursuant to this Section 1 (the "Shares") shall be subject to adjustment pursuant to Section 8 hereof.

Section 3 above, the holder may exercise, in whole or in part, the purchase rights evidenced hereby. Such exercise shall be effected by:



5.Net Exercise.In lieu of cash exercising this Warrant, the holder of this Warrant may elect to
receive shares equal to the value of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with notice of such election, in
which event the Company shall issue to the holder hereof a number of shares of Common Stock computed using the following formula:

Y (A - B)X =

A


WhereX 

The number of shares of Common Stock as to which this Warrant is being exercised.A 

The Exercise Price (as adjusted to the date of such calculations).


For
purposes of this Section 5 and Section 2 hereof, the fair market value of one share of Common Stock shall mean the average of the closing bid and asked prices of the
Common Stock quoted in the over-the-counter market in which the Common Stock is traded or the closing price quoted on any stock exchange or nation market system (i.e., the Nasdaq National
Market) on which the Common Stock is listed, whichever is applicable, as published in the Western Edition ofThe Wall Street Journalfor the ten (10)
trading days prior to the date of determination of fair market value. If the Common Stock is not traded on the over-the-counter market or on an exchange, the fair market value shall be the price per
share as shall be determined in good faith by the Company's Board of Directors.

6.Certificates for Shares.Upon the exercise of the purchase rights evidenced by this Warrant, one or
more certificates for the number of Shares so purchased shall be issued as soon as practicable thereafter, and in any event within twenty (20) days of the delivery of the subscription notice.

Section 6 ("Company Registrations") and Section 8 ("Registration on Form S-3") of the Rights Agreement to investors which are a party thereto.

10.Co-Sale Right.



11.Change of Control of the Company.If at any time the Company proposes to merge or consolidate with
or into any other corporation, effect any reorganization, or sell or convey all or substantially all of its assets to any other entity, then, as a condition of such reorganization, consolidation,
merger, sale or conveyance, the Company or its successor, as the case may be, shall enter into a supplemental agreement to make lawful and adequate provision whereby the Holder shall have the right to
receive, upon exercise of the Warrant, the kind and amount of equity securities which would have been received upon such reorganization, consolidation, merger, sale or conveyance by a holder of a
number of shares of common stock equal to the number of shares issuable upon exercise of the Warrant immediately prior to such reorganization, consolidation, merger, sale or conveyance. If the
property to be received upon such reorganization, consolidation, merger, sale or conveyance is not equity securities, the Company shall give the Holder of this Warrant ten (10) days prior written
notice of the proposed closing date of such transaction, and if this Warrant has not been exercised by or on the closing date of such transaction, it shall terminate.

12.No Fractional Shares or Scrip.No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant, but in lieu of such fractional shares the Company shall make a cash payment therefor on the basis of the Exercise Price then in effect.

13.No Stockholder Rights.Prior to exercise of this Warrant, the holder shall not be entitled to any
rights of a stockholder with respect to the Shares, including (without limitation) the right to vote such Shares, receive dividends or other distributions thereon, exercise preemptive rights or be

foregoing, this Warrant may be assigned, sold or otherwise transferred to an affiliate of GM, and such assignment, sale or transfer shall not require the consent of the Company so long as such
assignment, sale or transfer complies with applicable laws, rules and regulations. In the event of a merger or acquisition in which the Company is not the surviving entity, the Company shall obtain
written confirmation from the successor entity as to the valid and binding nature of this Warrant on such successor entity. Notwithstanding the foregoing, this Warrant may be pledged by GM in
connection with a hedging transaction not involving the Company's stock without the prior written consent of the Company, so long as such transaction and pledge complies with applicable laws, rules
and regulations.

15.Amendments and Waivers.Any term of this Warrant may be amended and the observance of any term of
this Warrant may be waived (either generally or in a particular instance and either retroactively or prospectively), with the written consent of the Company and GM. Any waiver or amendment effected in
accordance with this Section shall be binding upon GM, each holder of any Shares purchased under this Warrant at the time outstanding (including securities into which such Shares have been
converted), each future holder of all such Shares, and the Company.
