ABSENCE OF LITIGATION. Except as set forth in the Company's SEC Documents, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board or body pending or, to the knowledge of the Company, threatened against or affecting the Company, wherein an unfavorable decision, ruling or finding would have a material adverse effect on the properties, business or financial condition, results of operation or prospects of the 6 7 Company and its subsidiaries taken as a whole or the transactions contemplated by any of the Transaction Agreements or which would adversely affect the validity or enforceability of, or the authority or ability of the Company to perform its obligations under, any of the Transaction Agreements. k. ABSENCE OF EVENTS OF DEFAULT. Except as set forth in Section 3(e) hereof, no Event of Default (or its equivalent term), as defined in the respective agreement to which the Company is a party, and no event which, with the giving of notice or the passage of time or both, would become an Event of Default (or its equivalent term) (as so defined in such agreement), has occurred and is continuing, which would have a material adverse effect on the Company's financial condition or results of operations. l.

DILUTION. The number of Shares issuable upon conversion of the Preferred Stock and the exercise of the Warrants may increase substantially in certain circumstances, including, but not necessarily limited to, the circumstance wherein the trading price of the Common Stock declines prior to the conversion of the Preferred Stock. The Company's executive officers and directors have studied and fully understand the nature of the Securities being sold hereby and recognize that they have a potential dilutive effect. The board of directors of the Company has concluded, in its good faith business judgment, that such issuance is in the best interests of the Company. The Company specifically acknowledges that its obligation to issue the Shares upon 7 8 conversion of the Preferred Stock and upon exercise of the Warrants is binding upon the Company and enforceable regardless of the dilution such issuance may have on the ownership interests of other shareholders of the Company. 4.

TRANSFER AGENT INSTRUCTIONS. a. Promptly following the Closing Date, the Company will irrevocably instruct its transfer agent to issue Common Stock from time to time upon conversion of the Preferred Stock in such amounts as specified from time to time by the Company to the transfer agent, bearing the restrictive legend specified in Section 4(b) of this Agreement prior to registration of the Shares under the 1933 Act, registered in the name of the Buyer or its nominee and in such denominations to be specified by the Buyer in connection with each conversion of the Preferred Stock. The Company warrants that no instruction other than such instructions referred to in this Section 5 and stop transfer instructions to give effect to Section 4(a) hereof prior to registration and sale of the Shares under the 1933 Act will be given by the Company to the transfer agent and that the Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement, the Registration Rights Agreement, and applicable law. Nothing in this Section shall affect in any way the Buyer's obligations and agreement to comply with all applicable securities laws upon resale of the Securities. If the Buyer provides the Company with an opinion of counsel reasonably satisfactory to the Company that registration of a resale by the Buyer of any of the Securities in accordance with clause (1)(B) of Section 4(a) of this Agreement is not required under the 1933 Act, the Company shall (except as provided in clause (2) of Section 4(a) of this Agreement) permit the transfer of the Securities and, in the case of the Converted Shares or the Warrant Shares, as the case may be, promptly instruct the Company's transfer agent to issue one or more certificates for Common Stock without legend in such name and in such denominations as specified by the Buyer. b. Subject to the completeness and accuracy of the Buyer's representations and warranties herein, upon the conversion of any Preferred Stock by a person who is a non-U.S. Person, and following the expiration of any applicable Restricted Period (as those terms are defined in Regulation S), the Company, shall, at its expense, take all necessary action (including the issuance of an opinion of counsel) to assure that the Company's transfer agent shall issue stock certificates without restrictive legend or stop orders in the name of Buyer (or its nominee (being a non-U.S. Person) or such non-U.S. Persons as may be designated by Buyer) and in such denominations to be specified at conversion representing the number of shares of Common Stock issuable upon such conversion, as applicable. Nothing in this Section 5, however, shall affect in any way Buyer's or such nominee's obligations and agreement to comply with all applicable securities laws upon resale of the Securities. c. (i) The Company will permit the Buyer to exercise its right to convert the Preferred Stock by (x) telecopying an executed and completed Notice of Conversion to the Company at (610) 254-8958, Attn: Chairman (or such other telecopier number or addressee as may be identified by notice from the Company to the Buyer in the manner contemplated by Section 11 hereof) and (y) delivering, within five (5) business days thereafter, the original Notice of Conversion and the certificates for the Preferred Stock being converted to the Company by express courier, with a copy to the transfer agent. 11 12 (ii) The term "Conversion Date" means, with respect to any conversion elected by the holder of the Preferred Stock, the date specified in the Notice of Conversion, provided the copy of the Notice of Conversion is telecopied to or otherwise delivered to the Company in accordance with the provisions hereof so that is received by the Company on or before such specified date. If any of the foregoing conditions is not met, the Conversion Date shall be the first business day following actual receipt by the Company of the Notice of Conversion. (iii) The Company will transmit (or cause it transfer agent to transmit) the certificates representing the Converted Shares issuable upon conversion of any Preferred Stock (together with certificates representing the Preferred Stock not being so converted) to the Buyer via express courier, by electronic transfer or otherwise, within three (3) business days after receipt by the Company of the original Notice of Conversion and the certificate(s) representing the Preferred Stock being converted (the "Delivery Date"). d. The Company understands that a delay in the issuance of the shares of Common Stock beyond the Delivery Date could result in economic loss to the Buyer. As compensation to the Buyer for such loss, the Company agrees to pay late payments to the Buyer for late issuance of Shares upon Conversion in accordance with the following schedule (where "No. of Business Days Late" is defined as the number of business days beyond five (5) business days from Delivery Date: Late Payment For Each $10,000 No. of of Preferred Stock Liquidation Business Days Late Amount Being Converted ------------------ ------------------------------ 1 $100 2 $200 3 $300 4 $400 5 $500 6 $600 7 $700 8 $800 9 $900 10 $1,000 >10 $1,000+$200 for each Business Day Late beyond 10 days The Company shall pay any payments incurred under this Section in immediately available funds upon demand. Nothing herein shall limit the Buyer's right to pursue actual damages for the Company's failure to issue and deliver the Common Stock to the Buyer. Furthermore, in addition to any other remedies which may be available to the Buyer, in the event that the Company fails for any reason to effect delivery of such shares of Common Stock within five (5) business days after the Delivery Date, the Buyer will be entitled to revoke the relevant Notice of Conversion by delivering 12 13 a notice to such effect to the Company whereupon the Company and the Buyer shall each be restored to their respective positions immediately prior to delivery of such Notice of Conversion. e. If, by the relevant Delivery Date, the Company fails for any reason to deliver the Shares to be issued upon conversion of the Preferred Stock and after such Delivery Date, the holder of the Preferred Stock being converted (a "Converting Holder") purchases, in an open market transaction or otherwise, shares of Common Stock (the "Covering Shares") in order to make delivery in satisfaction of a sale of Common Stock by the Converting Holder (the "Sold Shares"), which delivery such Converting Holder anticipated to make using the Shares to be issued upon such conversion (a "Buy-In"), the Company shall pay to the Converting Holder, in addition to all other amounts contemplated in other provisions of the Transaction Agreements, and not in lieu thereof, the Buy-In Adjustment Amount (as defined below). The "Buy-In Adjustment Amount" is the amount equal to the excess, if any, of (x) the Converting Holder's total purchase price (including brokerage commissions, if any) for the Covering Shares over (y) the net proceeds (after brokerage commissions, if any) received by the Converting Holder from the sale of the Sold Shares.
