Subject to the vesting provisions of Section 2 below, the purchase rights under this Warrant may be exercised by Holder, in whole or in part, by the surrender of this Warrant at the principal office of the Company located at Chesterbrook Corporate Center, 851 Duportail Road, Suite 220, Wayne, Pennsylvania 19087, with the warrant exercise form attached hereto duly executed, and by the payment to the Company, by certified, cashier’s or other check acceptable to the Company, of an amount equal to the aggregate Warrant Price (as defined in Section 1.5 below) of the shares being purchased.

1.2.                              Net Issue Exercise. In lieu of exercising this Warrant pursuant to Section 1.1, Holder 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 Holder a number of shares of the Company’s Common Stock computed using the following formula:

1.3.                              Fair Market Value. For purposes of this Section 1, the “fair market value” of one share of the Company’s Common Stock shall mean:

1.3.1.                     The average of the closing bid and asked prices of the Common Stock in the over-the-counter market or the closing sale price quoted on any exchange on which the Common Stock is listed as published in The Wall Street Journal for the ten (10) trading days prior to the date of determination of fair market value; or

1.3.2.                     If the Common Stock is not traded in the over-the-counter market or on an exchange, the price per share which the Company could obtain from a willing buyer for shares sold by the Company from authorized but unissued shares as determined by the Company’s Board of Directors.

In the event that Holder disagrees with the determination of the Company’s Board of Directors pursuant to Section 1.3.2 above, Holder shall be entitled to retain, at its expense, a valuation firm to determine the fair market value of the Common Stock, and such determination shall be presented in writing to the Company. If Holder and the Company are unable to agree upon the fair market value of the Common Stock within five (5) business days following the Company’s receipt of such determination, the Company and Holder shall mutually appoint another independent valuation firm to determine me fair market value of the Common Stock. Such determination shall be final and binding upon the Company and Holder, and each of the Company and holder shall be responsible for fifty percent (50%) of the aggregate fees and expenses of such firm.

1.4.                              Stock Certificates. In the event of any exercise of the right to acquire Common Stock granted under this Warrant, certificates for the shares of Common Stock so purchased shall be issued in the name of, or as directed by, the Holder and delivered to Holder, or its designee (subject to Section 7 hereof), within a reasonable time and, unless this Warrant has been fully exercised or has expired, a new Warrant representing the shares with respect to which this Warrant shall not have been exercised shall also be issued to Holder, or its designee, within such time.

1.5.                              Warrant Price. The purchase price for the shares of Common Stock to be issued upon exercise of this Warrant under Section 1.1 herein shall be $11.2676 per share, subject to adjustment as provided in Section 4 herein (the “Warrant Price”).

4.                                       ADJUSTMENT

The kind of securities purchasable upon the exercise of this Warrant, the number of shares under this Warrant and the Warrant Price shall be subject to adjustment from time to time upon the happening of certain events, as follows:

4.1.                              Reclassification, Consolidation or Merger. In case of: (i) any reclassification or change of outstanding securities issuable upon exercise of this Warrant; (ii) any consolidation or merger of the Company with or into another corporation (other than a merger with another corporation in which the Company is a continuing corporation and which does not result in any reclassification, change or exchange of outstanding securities issuable upon exercise of this Warrant); or (iii) any sale or transfer to another corporation of all, or substantially all, of the property of the Company, then, and in each such event, the Company or such successor or purchasing corporation, as the case may be, shall execute a new Warrant which will provide that Holder shall have the right to exercise such new Warrant and purchase upon such exercise, in lieu of each share of Common Stock theretofore issuable upon exercise of this Warrant, the kind of securities, money and property receivable upon such reclassification, change, consolidation, merger, sale or transfer by a holder of Common Stock issuable upon exercise of this Warrant had this Warrant been considered exercised immediately prior to such reclassification, change, consolidation, merger, sale or transfer. Such new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 4 and the provisions of this Section 4 and the provisions of this Section 4.1 shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales and transfers.

4.3.                              Stock Dividends. If the Company, at any time while this Warrant is outstanding and unexpired, shall pay a dividend payable in, or make any other distribution to holders of, its capital stock (except any distribution described in Sections 4.1 and 4.2 hereof), then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of the security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of such additional stock of the Company which such holder would hold on the date of such exercise had it been the holder of record of the security receivable upon exercise of this Warrant on the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained such shares and/or all other additional stock available by it as aforesaid during such period, giving effect to all adjustments called for during such period by the provisions of this Section 4.

Holder hereby agrees that, in connection with any exercise of this Warrant, Holder shall become a party to that certain Second Amended and Restated Stockholders’ Agreement, dated as of November 17, 2000 (or similar successor agreement), by and among the Company and certain of its stockholders, (the “Stockholders’ Agreement”), such that for the purposes thereof, Holder shall be deemed to be an “Existing Investor” but only to the extent the Stockholders’ Agreement relates to the securities obtained from the exercise of this Warrant and Holder shall execute and deliver all documents necessary to effect the foregoing.

7.                                       RESTRICTIONS ON TRANSFER

7.1.                              Transfer of Warrant. This Warrant shall not be transferable by Holder, except (i) to an Affiliate or (ii) with the prior written consent of the Company (which consent shall not be unreasonably withheld); provided, that, in each such case, the transferee executes a written agreement to be bound by the provisions of this Section 7.1. For purposes of this Warrant, “Affiliate” shall mean, with respect to any person or entity, a person or entity that directly or indirectly, through, one or more intermediaries, controls, is controlled by or is under common control with the first mentioned person or entity; a person or entity shall be deemed to control another person or entity if such first person or entity possesses directly or indirectly the power to direct, or cause the direction of, the management and policies of the second person or entity, whether through the ownership of voting securities, by contract or otherwise.

7.2.                              Securities Laws Restrictions. Holder, by acceptance hereof, agrees that, absent an effective registration statement under the Securities Act of 1933, as amended, covering the Warrant or the disposition of Common Stock issued or issuable upon exercise hereof, Holder will not sell or transfer any or all of such Common Stock, without first providing the Company with an opinion of counsel reasonably acceptable to the Company and its counsel to the effect that such sale or transfer will be exempt from the registration requirements of the Securities Act of 1933, as amended, and Holder consents to the Company making a notation on its records in order to implement such restriction on transferability.

7.3.                              “Market Stand-Off” Agreement. Holder hereby agrees that, during the period of duration specified by the Company and an underwriter of Common Stock or other securities of the Company, following the date of the first sale to the public pursuant to a registration statement of the Company filed under the Securities Act of 1933, as amended, Holder shall not, to the extent requested by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase or otherwise transfer or dispose of (other than to donees or Affiliates who agree to be similarly bound) any securities of the Company received by Holder pursuant to this Warrant except Common Stock included in such registration; provided, however, that such agreement shall be applicable for a period of 180 days following consummation of the Company’s initial public offering and for such reasonable amount of time prior to such consummation as the underwriters may request, and for a period of 90 days following consummation of any subsequent public offering.

In order to enforce the foregoing covenant, the Company may impose stop transfer instructions with respect to the shares of Common Stock issuable upon exercise of this Warrant until the end of such period. Notwithstanding the foregoing, the obligations described in this Section 7.3 shall not apply to a registration relating solely to employee benefit plans on Form S-8 or similar forms which may be promulgated in the future, or a registration relating solely to a Securities and Exchange Commission Rule 145 transaction on Form S-4 or similar forms which may be promulgated in the future.
