The Exercise Price and thenumber of shares purchasable hereunder are subject to adjustment as provided in Section 4 of thisWarrant.1. Exercise; Issuance of Certificates; Acknowledgement. To the extent that thisWarrant is vested and exercisable with respect to any Warrant Shares, this Warrant shall beexercisable at the option of the holder of record hereof, at any time or from time to time up tothe Expiration Date for all or any part of such Warrant Shares (but not for a fraction of a share)for which this Warrant is vested and exercisable at such time. The Company agrees that the sharesof Common Stock purchased under this Warrant shall be and are deemed to be issued to the Holderhereof as the record owner of such shares as of the close of business on the date on which thisWarrant shall have been surrendered, properly endorsed, the completed, executed Form ofSubscription delivered and payment made for such shares. Certificates for the shares of the CommonStock so purchased, together with any other securities or property to which the Holder hereof isentitled upon such exercise, shall be delivered to the Holder hereof by the Company at theCompany’s expense within three business days after the rights represented by this Warrant have beenso exercised, and may bear a restrictive legend in substantially the form set forth in Section 3.6of the Agreement. Each certificate so delivered shall be in such denominations of the WarrantShares as may be requested by the Holder hereof and shall be registered in the name of such Holder.In case of a purchase of less than all the Warrant Shares, the Company shall execute and deliverto Holder within seven business days an Acknowledgement in the form attached hereto indicating thenumber of Warrant Shares which remain subject to this Warrant, if any, and the number of WarrantShares for which this Warrant is vested and exercisable at such time, if any. Notwithstandinganything to the contrary contained herein, unless the Holder otherwise notifies the Company or theExercise Price exceeds the fair market value of a Warrant Share (as determined in Section 2 below),this Warrant shall be deemed to be automatically exercised using the Net Issuance Method pursuantto Section 2 hereof immediately prior to the time on the Expiration Date at which this Warrantceases to be exercisable. In addition, the Holder may specify in its Form of Subscriptiondelivered to the Company (along with payment for the shares by cash or wire transfer) that theHolder’s exercise of any portion of this Warrant is contingent upon the closing of a then-pendingFundamental Transaction (as defined below). Upon any exercise of this Warrant, the Holder shall,if requested by the Company, confirm in writing, in a form satisfactory to the Company, that theWarrant Shares so purchased are being acquired solely for the Holder’s own account and not as anominee for any other party, for investment and not with a view toward distribution or resale andthat such Holder is an “accredited investor” as such term is defined in Rule 501(a)(1) ofRegulation D promulgated by the Securities and Exchange Commission under the Securities Act of1933, as amended. If the Holder cannot make such representations because they would be factuallyincorrect, it shall be a condition to such Holder’s exercise of this Warrant that the Companyreceive such other representations as the Company considers reasonably necessary to assure theCompany that the issuance of its securities upon exercise of this Warrant shall not violate anyUnited States or state securities laws.

2. Payment for Shares. The aggregate purchase price for Warrant Shares beingpurchased hereunder may be paid either (i) by cash or wire transfer of immediately available funds,(ii) if the fair market value of one (1) share of the Warrant Shares on the date of exercise isgreater than the Exercise Price, by surrender of a number of Warrant Shares which have a fairmarket value equal to the aggregate purchase price of the Warrant Shares being purchased (“NetIssuance”) as determined herein, or (iii) any combination of the foregoing. If the Holder electsthe Net Issuance method of payment, the Company shall issue to Holder upon exercise a number ofshares of Warrant Shares determined in accordance with the following formula:    X= Y(A-B)  A       where: X = the number of Warrant Shares to be issued to the Holder;       Y = the number of Warrant Shares with respect to which the Holder isexercising its purchase rights under this Warrant;       A = the fair market value of one (1) share of the Warrant Shares on thedate of exercise; and       B = the Exercise Price.No fractional shares arising out of the above formula for determining the number of shares tobe issued to the Holder shall be issued, and the Company shall in lieu thereof make payment to theHolder of cash in the amount of such fraction multiplied by the fair market value of one (1) shareof the Warrant Shares on the date of exercise. For purposes of the above calculation, the fairmarket value of one (1) share of the Warrant Shares shall mean (a) if the Common Stock is thentraded on a securities exchange, the average of the closing prices of such Common Stock on suchexchange over the ten (10) calendar day period ending three (3) days prior to the date of exercise,(b) if the Common Stock is then regularly traded over-the-counter, the average of the closing saleprices or secondarily the closing bid of such Common Stock over the ten (10) calendar day periodending three (3) days prior to the date of exercise, or (c) if there is no active public market forthe Common Stock, the fair market value of one share of the Warrant Shares as determined in goodfaith by the Board of Directors of the Company.3. Reservation of Shares; Shares to be Fully Paid. The Company covenants and agreesthat all shares of Common Stock which may be issued upon the exercise of the rights represented bythis Warrant will, upon issuance, be duly authorized, validly issued, fully paid and nonassessableand free from all preemptive rights of any stockholder and free of all taxes, liens and chargeswith respect to the issue thereof. The Company represents and warrants that it has reserved asufficient number of authorized but unissued shares of Common Stock to provide for the exercise ofthe rights represented by this Warrant (assuming full vesting thereof).

In case the Company shall at any timesubdivide its outstanding shares of Common Stock into a greater number of shares or pay a dividendin Common Stock in respect of outstanding shares of Common Stock, the Exercise Price in effectimmediately prior to such subdivision or at the record date of such dividend shall beproportionately reduced, and conversely, in case the outstanding shares of the Common Stock of theCompany shall be combined into a smaller number of shares, including by means of a reverse stocksplit, the Exercise Price in effect immediately prior to such combination shall be proportionatelyincreased.4.2 Reclassification. If any reclassification of the capital stock of the Companyshall be effected in such a way that holders of Common Stock shall be entitled to receive stock,securities, or other assets or property, then, as a condition of such reclassification, lawful andadequate provisions shall be made whereby the Holder hereof shall thereafter have the right topurchase and receive (in lieu of the shares of the Common Stock immediately theretofore purchasableand receivable upon the exercise of the rights represented hereby) such shares of stock, securitiesor other assets or property as may be issued or payable with respect to or in exchange for a numberof outstanding shares of such Common Stock equal to the number of shares of such Common Stockimmediately theretofore purchasable and receivable upon the exercise of the rights representedhereby. In any reclassification described above, appropriate provision shall be made with respectto the rights and interests of the Holder of this Warrant to the end that the provisions hereof(including, without limitation, provisions for adjustments of the Exercise Price and of the numberof shares purchasable and receivable upon the exercise of this Warrant) shall thereafter beapplicable, as nearly as may be, in relation to any shares of stock, securities or assetsthereafter deliverable upon the exercise hereof.4.3 Notice of Adjustment.

For purposes of any suchexercise, the determination of the Exercise Price shall be appropriately adjusted to reflect theamount of New Consideration issuable in respect of one share of Common Stock in such FundamentalTransaction, and the Company shall apportion the Exercise Price among the New Consideration in areasonable manner reflecting the relative value of any different components of the NewConsideration. If holders of Common Stock are given any choice as to the securities, cash orproperty to be received in a Fundamental Transaction, then the Holder shall be given the samechoice as to the New Consideration it receives upon any exercise of this Warrant following suchFundamental Transaction.
