A Warrant shall be deemed to have been exercised immediately prior to the close of business on the Exercise Date, provided that the Warrant Certificate representing such Warrant, with the exercise form thereon duly executed by the Registered Holder thereof or his attorney duly authorized in writing, together with payment in cash or by check made payable to the Company, of an amount in lawful money of the United States of America equal to the applicable Purchase Price has been received in good funds by the Company.

If more than one Warrant 3 Certificate shall be exercised at one time by the same Registered Holder, the number of full shares of Common Stock which shall be issuable upon exercise thereof shall be computed on the basis of the aggregate number of full shares of Common Stock issuable upon such exercise. As soon as practicable on or after the Exercise Date and in any event with ten business days after such date, the Company shall cause to be issued to the person or persons entitled to receive the same a Common Stock certificate or certificates for the shares of Common Stock deliverable upon such exercise, and the Company shall deliver the same to the person or persons entitled thereto.

Reservation of Shares: Listing of Taxes; etc. (a) The Company covenants that it will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issue upon exercise of Warrants, such number of shares of Common Stock as shall then be issuable upon the exercise of all outstanding Warrants. The Company covenants that all shares of Common Stock which shall be issuable upon exercise of the Warrants shall, at the time of delivery thereof and upon payment of the Purchase Price with respect thereto, be duly and validly issued and fully paid and nonassessable and free from all preemptive or similar rights, taxes, liens and charges with respect to the issue, thereof except for taxes and other charges payable by the holder as provided in Section 5(b), and that upon issuance such shares shall be listed on each securities exchange, if any, on which the other shares of outstanding Common Stock of the Company are then listed. (b) The Company shall pay all documentary, stamp or similar taxes and other governmental charges that may be imposed with respect to the issuance of Warrants, or the issuance or delivery of any shares of Common Stock upon exercise of the Warrants; provided, however, that if shares of Common Stock are to be delivered in a name other than the name of the Registered Holder of the Warrant Certificate representing any Warrant being exercised, (provided that such issuance is permitted under any applicable federal or state securities laws) then no such delivery shall be made unless the person requesting the same has paid to the Company the amount of transfer taxes or charges incident thereto, if any. SECTION 6. Exchange and Registration of Transfer (a) Warrant Certificates may be exchanged for other Warrant Certificates representing an equal aggregate number of Warrants, or, subject to the limitations set forth in Section 6 (g) hereof, may be transferred in whole or in part. Warrant Certificates to be so exchanged shall be surrendered to the Company at 2000 Cabot Boulevard West, Suite 110, Langhorne, Pennsylvania 19047, to the attention of Gerald W. Klein, and the Company shall execute, 4 issue and deliver in exchange therefor to the Registered Holder a new Warrant Certificate or Certificates representing an equal aggregate number of Warrants. (b) The Company shall keep, at such office, books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates, and the transfer thereof. Upon due presentment for registration of transfer of any Warrant Certificate at such office, the Company shall execute and shall issue and deliver to the Registered Holder a new Warrant Certificate or Certificates representing an equal aggregate number of Warrants. (c) With respect to any Warrant Certificates presented for registration or transfer, or for exchange or exercise, the subscription or assignment form accompanying the Warrant Certificate(s), as the case may be, attached thereto shall be duly endorsed or be accompanied by a written instrument or instruments of transfer or subscription, in form satisfactory to the Company, duly executed by the Registered Holder thereof or his attorney duly authorized in writing. (d) No service charge shall be made for any exchange of registration or transfer of Warrant Certificates. However, the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. (e) All Warrant Certificates surrendered for exercise or for exchange shall be promptly canceled by the Company. (f) Prior to due presentment for registration or transfer thereof, the Company may deem and treat the Registered Holder of any Warrant Certificate as the absolute owner thereof of each Warrant represented thereby (notwithstanding any notations of ownership or writing thereon made by anyone other than the Company) for all purposes and shall be affected by any notice to the contrary. (g) The Warrants represented by the Warrant Certificates may not be exercised nor may any interest in the Warrants represented by the Warrant Certificates be sold, assigned, pledged, hypothecated, encumbered or in any other manner transferred or disposed of, in whole or in part, except in compliance with applicable United States federal and state securities laws and the terms and conditions hereof. Each Warrant Certificate shall bear the legend set forth in Section 14 hereof. Each share of Common Stock issued upon exercise of the Warrants shall bear a legend substantially in the form set forth in Section 14 hereof.

The provisions of this Section 6 (g) shall be binding upon all subsequent holders of Warrant Certificates. 5 SECTION 7. Loss or Mutilation. Upon receipt by the Company of evidence satisfactory to it to the ownership of the loss, theft, destruction or mutilation of any Warrant Certificate and (in the case of loss, theft or destruction) of indemnity satisfactory to them, and (in case of mutilation) upon surrender and cancellation thereof, the Company shall execute and deliver in lieu thereof a new Warrant Certificate to the Registered Holder thereof representing an equal aggregate number of Warrants. Applicants for a substitute Warrant Certificate shall also comply with such other reasonable regulations and pay such other charges as the Company may prescribe. SECTION 8. Adjustment of Purchase Price and Number of Shares of Common Stock Deliverable. (a) (i) Except as hereinafter provided, in the event the Company shall, at any time or from time to time after the date hereof, sell any shares of Common Stock for a consideration per share less than the Purchase Price or issue any shares of Common Stock as a stock dividend to the holders of Common Stock, or subdivide or combine the outstanding shares of Common Stock into a greater or lesser number of shares (any such sale, issuance, subdivision or combination being herein called a "Change of Shares"), then, and thereafter upon each further Change of Shares, the Purchase Price for the Warrants (whether or not the same shall be issued and outstanding) in effect immediately prior to such Change of Shares shall be changed to a price (including any applicable fraction of a cent to the nearest cent) equal to the following: NPP = (OB x OPP) + (NS x NSP) OA where: NPP = the New Purchase Price OPP = the existing Purchase Price immediately OB = before the new issue the total outstanding shares of Common Stock immediately before Change of Shares NS = number of shares sold or issued pursuant to the Change of Shares NSP = price per share of new issue OA = the total outstanding shares of Common Stock immediately after the Change of Shares provided, however, that in no event shall the Purchase Price be adjusted pursuant to this computation to an amount in excess of the Purchase Price in effect immediately prior to such computation, except in the case of a combination of outstanding shares of Common Stock. For the purposes of any adjustment to be made in accordance with this Section 8 (a) the following provisions shall be applicable: (A) In case of the issuance or sale of shares of Common Stock (or of other securities deemed hereunder to involve the issuance or sale of shares of Common 6 Stock) for a consideration part or all of which shall be cash, the amount of the cash portion of the consideration therefor deemed to have been received by the Company shall be (i) the subscription price, if shares of Common Stock are offered by the Company for subscription, or (ii) the public offering price (before deducting therefrom any compensation paid or discount allowed in the sale, underwriting or purchase thereof by underwriters or dealers or others performing similar services), if such securities are sold to underwriters or dealers for public offering without a subscription offering, or (iii) the gross amount of cash actually received by the Company for such securities in any other case, in each case, without deduction for any expenses incurred by the Company in connection with such transaction. (B) In case of the issuance or sale (otherwise than as a dividend or other distribution on any stock of the Company) of shares of Common Stock (or of other securities deemed hereunder to involve the issuance or sale of shares of Common Stock) for a consideration part or all of which shall be other than cash, the amount of the consideration therefor other than cash deemed to have been received by the Company shall be the value of such consideration as determined in good faith by the Board of Directors of the Company. (C) Shares of Common Stock issuable by way of dividend or other distribution on any stock of the Company shall be deemed to have been issued immediately after the opening of business on the day following the record date for the determination of shareholders entitled to receive such dividend or other distribution and shall be deemed to have been issued without consideration. (D) The reclassification of securities of the Company other than shares of Common Stock into securities including shares of Common Stock shall be deemed to involve the issuance of such shares of Common Stock for a consideration other than cash immediately prior to the close of business on the date fixed for the determination of security holders entitled to receive such shares, and the value of the consideration allocable to such shares of Common Stock shall be determined as provided in subsection (B) of this Section 8(a). (E) The number of shares of Common Stock at any one time outstanding shall be deemed to include the aggregate maximum number of shares issuable (subject to readjustment upon the actual issuance thereof) upon the exercise of options, rights or warrants and upon the conversion or exchange of convertible or exchangeable securities. (ii) Upon each adjustment of the Purchase Price pursuant to this Section 8, the number of shares of Common Stock purchasable upon the exercise of each Warrant shall be the number derived by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment by the Purchase Price in effect prior to such adjustment and dividing the product so obtained by the applicable adjusted Purchase Price. (b) Except as hereinafter provided, in case the Company shall at any time after the date hereof issue options, rights or warrants to subscribe for shares of Common 7 Stock (whether as part of a package of securities such as units, or otherwise, herein "Units"), or issue any securities convertible into or exchangeable for shares of Common Stock, for a consideration per share (determined as provided in Section 8(a) and as provided below) less than the Purchase Price in effect immediately prior to the earlier of the issuance of such options, rights or warrants, or such convertible or exchangeable securities or the record date therefor, or without consideration (including the issuance of any such securities by way of dividend or other distribution), the Purchase Price for the Warrants (whether or not the same shall be issued and outstanding) in effect immediately prior to the issuance of such options, Units, rights or warrants, or other such convertible or exchangeable securities, as the case may be, shall be reduced to a price determined by making the computation in accordance with the provisions of Section 8(a) hereof, provided that: (A) The aggregate maximum number of shares of Common Stock, as the case may be, issuable or that may become issuable under such options, rights, Units or warrants (assuming exercise in full even if not then currently exercisable or currently exercisable to full) shall be deemed to be issued and outstanding at the time such options, rights, Units, or warrants were issued, for a consideration equal to the minimum purchase or exercise price per share provided for in such options, rights or warrants at the time of issuance, plus the consideration, if any, received by the Company upon the issuance of such options, rights, Units or warrants (without deduction for expenses incurred or amounts paid to any underwriter by the Company in connection with such issuance); provided, however, that upon the expiration or other termination of such options, rights or warrants, if any thereof shall not have been exercised, the number of shares of Common Stock deemed to be issued and outstanding pursuant to this subsection (A) (and for the purposes of subsection (E) of Section 8(a) hereof) shall be reduced by the number of shares as to which options, warrants and/or rights outstanding, and the Purchase Price then in effect shall forthwith be readjusted and thereafter be the price that it would have been had adjustment been made on the basis of the issuance only of the shares actually issued plus the shares remaining issuable upon the exercise of those options, rights or warrants as to which the exercise rights shall not have expired or terminated unexercised. (B) The aggregate maximum number of shares of Common Stock issuable or that may become issuable upon conversion or exchange of any convertible or exchangeable securities (assuming conversion or exchange in full even if not then currently convertible or exchangeable in full) shall be deemed to be issued and outstanding at the time of issuance of such securities, for a consideration equal to the consideration received by the Company upon the issuance of such securities (without deduction for expenses incurred or amounts paid to any underwriter in connection with such issuance), plus the minimum consideration, if any, receivable by the Company upon the conversion or exchange thereof; provided, however, that upon the termination of the right to convert to or exchange such convertible or exchangeable securities (whether by reason or redemption or otherwise), the number of shares of Common Stock deemed to be issued and outstanding pursuant to this subsection (B) (and for the purposes of subsection (E) of Section 8(a) hereof) shall be reduced by the number of shares as to which the conversion or exchange rights shall have expired or terminated unexercised, and such number of shares shall no longer be deemed to be 8 issued only of the shares actually issued plus the shares remaining issuable upon conversion or exchange rights shall not have expired or terminated unexercised. (C) If any change shall occur in the price per share provided for in any of the options, rights or warrants referred to in subsection (A) of this Section 8(b), or in the price per share or ratio at which the securities referred to in subsection (A) of this Section 8(b) are convertible or exchangeable (in either case, other than changes in such prices or ratios arising pursuant to antidilution adjustments in such options, rights, Units, warrants or convertible or exchangeable securities or the instruments pursuant to which they were issued, provided that such options, rights, warrants, convertible or exchangeable securities or instruments pursuant to which they were issued do not contain antidilution provisions any more favorable to the holder thereof than those contained herein) such options, rights, Units, or warrants or conversion or exchange rights, as the case may be, to the extent not theretofore exercised, shall be deemed to have expired or terminated on the date when such price change became effective in respect of shares not theretofore issued pursuant to the exercise or conversion or exchange thereof, and the Company shall be deemed to have issued upon such date new options, rights, Units or warrants or convertible or exchangeable securities. (c) In case of any reclassification or change of outstanding shares of Common Stock issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value or as a result of subdivision or combination), or in case of any consolidation or merger of the Company with or into another corporation (other than a merger in which the Company is the continuing corporation and which does not result in any reclassification or change of the then outstanding shares of Common Stock or other capital stock issuable upon exercise of the Warrants (other than a change in par value or from par value or to no par value, or from no par value to par value or as a result of subdivision or combination)) or in case of any sale or conveyance to another corporation of the property of the Company as an entirety or substantially as an entirety, then, as a condition of such reclassification, change, consolidation, merger, sale or conveyance, the Company, or such successor or purchasing corporation, as the case may be, shall make lawful and adequate provision whereby the Registered Holder of each Warrant shall have the right thereafter to receive on exercise of such Warrant the kind and amount of securities and property receivable upon such reclassification, change, consolidation, merger, sale or conveyance by a holder of the number of securities issuable upon exercise of such Warrant immediately prior to such reclassification, change, consolidation, merger, sale or conveyance. Such provisions shall include provision for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in Sections 8(a) and (b). The above provisions of this Section 8(c) shall similarly apply to successive reclassification and changes of shares of Common Stock and to successive consolidations, mergers, sales or conveyances. (d) Irrespective of any adjustments or changes in the Purchase Price or the number of shares of Common Stock purchasable upon exercise of the Warrants, the Warrant Certificates theretofore and thereafter issued shall, unless the Company shall exercise its option to issue new Warrant Certificates pursuant to Section 2(e) hereof, continue to express the Purchase 9 Price per share and the number of shares purchasable thereunder as the Purchase Price per share and the number of shares purchasable thereunder were expressed in the Warrant Certificates when the same were originally issued. (e) After each adjustment of the Purchase Price pursuant to this Section 8, the Company will promptly prepare a certificate signed by the Chairman or Vice President, and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary, of the Company setting forth: (i) the Purchase price as so adjusted, (ii) the number of shares of Common Stock purchasable upon exercise of each Warrant, after such adjustment, and (ii) a brief statement of the facts accounting for such adjustment. The Company will cause a brief summary thereof to be sent by ordinary first class mail to each Registered Holder at his last address as it shall appear on the books of the Company. No failure to mail such notice nor any defect therein or in the mailing thereof shall affect the validity thereof except as to the holder to whom the Company failed to mail such notice, or except as to the holder whose notice was defective. The affidavit of the Secretary or an Assistant Secretary of the Company that such notice has been mailed shall, in the absence of fraud, be prima facie evidence of the facts stated therein. (f) No adjustment of the Purchase Price or in the number of shares of Common Stock issuable upon exercise of the Warrants shall be made as a result of or in connection with (A) the issuance or sale of shares of Common Stock pursuant to options, warrants and convertible or exchangeable securities outstanding or in effect or provided for on the date hereof, (B) the issuance or sale of shares of Common Stock upon the exercise of options referred to in clause (A) above, (C) the issuance of shares of Common Stock pursuant to the exercise of options to purchase Common Stock granted to employees of the Company pursuant to the Company's Amended and Restated 1995 Stock Option Plan (D) the issuance or sale of shares of Common Stock if the amount of said adjustment shall be less than $.05, provided, however, that in such case, any adjustment that would otherwise be required then to be made shall be carried forward and shall be made at the time of and together with the next subsequent adjustment that shall amount, together with any adjustment so carried forward, to at least $.05.
