THIS CERTIFIES THAT, for value received, __________________ with a principal residence or business at _____________________________________ (the “Holder”) is entitled to purchase from AHPC Holdings, Inc., a Maryland corporation (the “Company”), at any time or from time to time after the date hereof and ending at 5:00 p.m. Chicago, Illinois time on the fifth (5th) calendar anniversary of the date hereof, __________ shares (the “Shares”) of common stock of the Company (the “Common Stock”). Each Share subject to this Warrant may be purchased for a price per share equal to $3.50 (the “Warrant Price”).

1.   Method of Exercise; Payment; Issuance of New Warrant; Mandatory Conversion .

(a)   Method of Exercise; Payment . The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part and from time to time any time after the date hereof, by (i) the surrender of this Warrant (with a notice of exercise in the form attached hereto as Exhibit A, duly executed) at the principal office of the Company and (ii) the payment to the Company, by check or wire transfer of funds to an account specified in writing by the Company, of an amount equal to the Warrant Price times the number of Shares being exercised. (b) Issuance of New Warrant. In the event that all Shares represented by this Warrant are not exercised, the Company shall within five (5) business days issue to Holder a new Warrant for the unexercised Shares, such Warrant as shall be identical in all respects to this Warrant except for the number of Shares it represents.

           (b)   Issuance of New Warrant . In the event that all Shares represented by this Warrant are not exercised, the Company shall within five (5) business days issue to Holder a new Warrant for the unexercised Shares, such Warrant as shall be identical in all respects to this Warrant except for the number of Shares it represents.

           (c)   Mandatory Conversion . In the event that the closing price of the Common Stock on NASDAQ (or any other national exchange or quoting system on which the Common Stock trades if no longer traded on NASDAQ) exceeds $8.75 for fifteen (15) consecutive trading days, this Warrant shall be automatically exercised in full in a cashless exchange. The number of common shares to be issued as a result of the cashless exchange shall be equal to the average closing stock price of the Common Stock on the fifteen days preceding the date of exercise minus the Warrant Price, with such difference multiplied by the number of Shares being exercised, and finally such product being divided by the Warrant Price. The average price of the Common Stock used in determining the number of shares that shall be issued to Holder upon the mandatory conversion of this Warrant shall be computed by adding together the closing price on NASDAQ (or any other national exchange or quoting system on which the Common Stock trades if no longer traded on NASDAQ) for each of the fifteen days and dividing that sum by that number of days (fifteen).

2.   Stock Fully Paid; Reservation of Shares . All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all preemptive rights, taxes, liens and charges with respect to the issue thereof; provided, however, that the Company shall not be required to pay any transfer taxes with respect to the issue of shares in any name other than that of the registered holder hereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. The Company shall at all times take all such action and obtain all such permits or orders as may be necessary to enable the Company lawfully to issue such Common Stock as duly and validly issued, fully paid and nonassessable shares upon exercise in full of this Warrant.

3.   Fractional Shares . No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the current market price of such Shares then in effect as determined in good faith by the Company’s Board of Directors.

4.   Adjustment . This Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

           (a)   Adjustment for Stock Splits and Combinations . If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Stock, the Warrant Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Stock, the Warrant Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective.

           (b)   Adjustment for Certain Dividends and Distributions . In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Warrant Price shall be decreased as of the time of such issuance, by multiplying the Warrant Price by a fraction:

           (c)   Adjustments for Other Dividends and Distributions . In the event the Company at any time or from time to time after the date hereof shall make or issue a dividend or other distribution payable in securities of the Company other than Common Stock, then and in each such event, provision shall be made so that the Holder shall receive upon exercise hereof in addition to the number of shares of Common Stock receivable thereupon, the amount of securities of the Company that it would have received had this Warrant been exercised on the date of such event and had the Holder thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by it as aforesaid during such period, given application to all adjustments called for during such period, under this Section 4.

           (d)   Adjustment of Number of Shares . Upon each adjustment of the Warrant Price pursuant to this Section 4, the number of shares of Common Stock purchasable upon exercise of this Warrant shall be adjusted to the number of shares of Common Stock, calculated to the nearest one hundredth of a share, obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of the Warrant by the Warrant Price in effect prior to such adjustment and dividing the product so obtained by the new Warrant Price.

           (e)   Adjustment for Reclassification, Exchange and Substitution . If the Common Stock issuable upon the exercise of this Warrant are changed into the same or different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination provided for in Subsection (a) above, a dividend or distribution provided for in Subsection (b) or (c) above, or a reorganization, merger, consolidation or sale of assets, provided for in Subsection (f) below), then and in any such event the Holder shall have the right thereafter to exercise this Warrant into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change, by holders of the number of shares of Common Stock for which this Warrant might have been exercised immediately prior to such recapitalization, reclassification or change.

           (f)   Reorganization, Mergers, Consolidations or Sales of Assets . If at any time or from time to time there is a capital reorganization of the Common Stock (other than a subdivision or combination provided for in Subsection (a) above, a dividend or distribution provided for in Subsection (b) or (c) above, or a reclassification or exchange of shares provided for in Subsection (e) above) or a merger or consolidation of the Company with or into another corporation, or the sale of all or substantially all of the Company’s properties and assets to any other person, then, as a part of such reorganization, merger, consolidation or sale, provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant, upon payment of the Warrant Price
