R E C I T A L S A. The Boards of Directors of Parent and the Company each have determined that a business combination between Parent and the Company would enable the companies to achieve long-term strategic and financial benefits and, accordingly, is in the best interests of their respective stockholders. Each of such Boards of Directors desires to effect the Merger (as defined herein), on the terms and subject to the conditions set forth herein. B. It is intended that the Merger qualify as a reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the "CODE"), for federal income tax purposes. C. It is intended that the Merger be accounted for as a pooling of interests for financial accounting purposes. D. Parent has incorporated and organized Merger Sub solely to facilitate the Merger. NOW, THEREFORE, in consideration of the mutual covenants and subject to the terms and conditions set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: ARTICLE 1 THE MERGER 1.1. THE BASIC TRANSACTION. On the terms and subject to the conditions of this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into the Company in accordance with this Agreement, and the separate corporate existence of Merger Sub shall thereupon cease (the "MERGER"). The Company shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the "SURVIVING CORPORATION"), and shall become a wholly owned subsidiary of Parent. The Merger shall have the effects specified in the New Jersey Business Corporation Act (the "NJBCA"). 1.2. THE CLOSING. Subject to the terms and conditions of this Agreement, the closing of the Merger (the "CLOSING") shall take place (a) at the offices of Thelen, Reid & Priest LLP, New York, New York at 10:00 a.m., local time, on the first business day immediately following the day on which the last to be fulfilled or waived of the conditions set forth in Article 6 shall be completely fulfilled or waived in accordance herewith, or (b) at such other time, date or place as Parent and the Company may agree.

The directors and officers of Merger Sub immediately prior to the Effective Time shall be the directors and officers of the Surviving Corporation until their successors are duly appointed or elected in accordance with applicable law; and Joseph Stach, president and chief executive officer of the Company, also shall become an officer of the Surviving Corporation. ARTICLE 2 CONVERSION AND EXCHANGE OF SECURITIES 2.1. MERGER SUB STOCK. At the Effective Time, each share of common stock, par value $0.01 per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation. 2.2. COMPANY STOCK; OPTIONS. (a) EXCHANGE RATIO. At the Effective Time, each share of common stock, par value $0.01 per share, of the Company ("COMPANY COMMON STOCK") that is issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive the number of shares of common stock, par value $0.001 per share, of Parent (the "PARENT COMMON STOCK") that is equal to 3,750,000 divided by the number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time (the "EXCHANGE RATIO"); provided, however, that (A) if the Closing Price (as defined in this Section 2.2) is less than or equal to $12.11, then the Exchange Ratio shall be the result obtained by dividing $3.74 by the Closing Price, but in no event shall the Exchange Ratio computed pursuant to this clause (A) be greater than 4,000,000 divided by the number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time (the "EFFECTIVE TIME SHARE NUMBER") and (B) if the Closing Price is greater than or equal to $16.39, the Exchange Ratio shall be the result obtained by dividing, $5.06 by the Closing Price, but in no event shall the Exchange Ratio computed pursuant to this clause (B) be less than 3,500,000 divided by the Effective Time Share Number. "CLOSING PRICE" means the average closing price of the Parent Common Stock, as reported in The Wall Street Journal, Eastern Edition, for each of the 10 consecutive Trading Days immediately preceding the third Trading Day prior to the Stockholders Meeting (as defined in Section 5.4). "TRADING DAY" means a day on which trading is conducted on the Nasdaq National Market. (b) CANCELLATION OF COMPANY COMMON STOCK. At the Effective Time, as a result of the Merger and without any action on the part of the holders thereof, all shares of Company Common Stock shall cease to be outstanding, shall be canceled and retired and shall cease to exist, and each holder of shares of Company Common Stock shall thereafter cease to have any rights with respect to such shares of Company Common Stock, except the right to receive upon the surrender of a certificate (a "CERTIFICATE") representing such shares of Company Common Stock (i) the number of shares of Parent Common Stock determined in accordance with this Section 2.2, and (ii) cash, without interest, payable (A) in lieu of any fractional shares of Parent Common Stock, in accordance with Section 2.3(b), and (B) as Specified Post-Closing Dividends (as defined in Section 2.3), in accordance with Section 2.3(f). (c) TREASURY SHARES AND SHARES HELD BY SUBSIDIARIES. At the Effective Time, as a result of the Merger and without any action on the part of Parent, Merger Sub or the Company, any and all shares of Company Common Stock issued and held in the Company's treasury or held by a Subsidiary of the Company shall cease to be outstanding, shall be canceled and retired without payment of any consideration therefor and shall cease to exist. (d) OPTIONS. (i) At the Effective Time, as a result of the Merger and without any action on the part of holder thereof, each option to purchase Company Common Stock granted by the Company (collectively, "COMPANY OPTIONS") under one of its stock option plans (collectively, "COMPANY OPTION PLANS") that remains outstanding and unexercised as of the Effective Time, whether or not vested or exercisable, shall be assumed by Parent and shall be converted into an option to purchase Parent Common Stock (collectively, "SUBSTITUTED OPTIONS"). (ii) Subject to subsection 2.2(d)(iii) below, (A) the number of shares of Parent Common Stock underlying a Substituted Option shall be equal to the number of shares of Company Common Stock underlying the subject Company Option multiplied by the Exchange Ratio and rounded to the nearest whole number, (B) the exercise price per share of a Substituted Option shall be equal to the exercise price of the subject Company Option divided by the Exchange Ratio and rounded to the nearest cent, and (C) each Substituted Option shall be exercisable on the same terms and subject to the same conditions as had been applicable to the related Company Option, except to the extent the number of shares and exercise price per share have been adjusted pursuant to (A) and (B), respectively, of this subsection 2.2(d)(ii). (iii) It is the intention of the parties that Company Options that qualified as incentive stock options, within the meaning of Section 422 of the Code ("ISOS"), immediately prior to the Effective Time, be converted, when assumed by Parent, into Substituted Options that qualify as ISOs immediately following the Effective Time, to the extent permitted by Section 422 of the Code and applicable terms of the Company Option Plans. In furtherance of such intention, the formulae, terms and conditions set forth in subsection 2.2(d)(ii) above may be applied to, or modified for, such Substituted Options as deemed reasonably necessary by Parent, so long as any such application or modification does not reduce the benefit of the Substituted Option to the holder thereof. (iv) On or prior to the Effective Time, Parent shall file with the Securities and Exchange Commission (the "COMMISSION") a Registration Statement on Form S-3 or Form S-8, as determined by Parent in its sole discretion, relating to the issuance of the Parent Common Stock underlying the Substituted Options or shall cause such Parent Common Stock to be included in an effective Registration Statement on Form S-8 relating to one or more of Parent's stock option plans (collectively, "PARENT OPTION PLANS"). So long as any Substituted Options remain outstanding, Parent shall use its best efforts to maintain the effectiveness of any Registration Statement or Statements relating to the Substituted Options (and to maintain the current status of the prospectus or prospectuses related thereto). At or prior to the Effective Time, Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon exercise of the Substituted Options. 2.3. EXCHANGE OF CERTIFICATES REPRESENTING COMPANY COMMON STOCK. (a) As of the Effective Time, Parent shall deposit, or shall cause to be deposited, with an exchange agent reasonably acceptable to the Company (the "EXCHANGE AGENT"), for the benefit of the holders of Company Common Stock, for exchange in accordance with this Article 2, (i) certificates representing the shares of Parent Common Stock to be issued in connection with the Merger ("MERGER CERTIFICATES"), and (ii) Parent's good faith estimate of the cash in lieu of fractional shares expected to be payable in connection with the Merger. Such cash and Merger Certificates are referred to herein as the "EXCHANGE FUND." (b) No fractional shares of Parent Common Stock shall be issued pursuant hereto. In lieu of the issuance of any fractional share of Parent Common Stock, cash will be paid in respect of any fractional share of Parent Common Stock that would otherwise be issuable, and the amount of such cash shall be equal to such fractional proportion of the Closing Price. No interest will be paid or accrued on the cash payable to holders of shares of Company Common Stock. (c) Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of Company Common Stock (i) a letter of transmittal, in a form and having such provisions as Parent may reasonably specify ("LETTER OF TRANSMITTAL"), which shall advise the holder that delivery of Merger Certificates shall be effected, and risk of loss and title to such holder's shares of Company Common Stock shall pass, only upon delivery of the Certificates representing such shares to the Exchange Agent, and (ii) instructions for use in effecting the surrender of such Certificates in exchange for Merger Certificates and cash in lieu of fractional shares from the Exchange Fund. (d) Upon surrender of a Certificate to the Exchange Agent for cancellation, together with a duly executed and properly completed Letter of Transmittal, (i) the holder of the shares of Company Common Stock represented by such Certificate shall be entitled to receive in exchange therefor from the Exchange Fund (A) a Merger Certificate representing that number of whole shares of Parent Common Stock determined by multiplying the number of shares of Company Common Stock represented by the Certificate by the Exchange Ratio, and (B) a check representing (1) the amount of cash in lieu of fractional shares of Parent Common Stock, if any, determined pursuant to paragraph (b) of this Section 2.3, and (2) any Specified Post-Closing Dividends, in each case less any applicable tax withholding, and (ii) the Company Common Stock represented by the surrendered Certificate shall thereupon be canceled. (e) In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, a Merger Certificate representing the proper number of shares of Parent Common Stock, together with a check for the cash to be paid in lieu of fractional shares, if any, may be issued to such transferee of such Company Common Stock, if the Certificate representing such Company Common Stock is presented to the Exchange Agent, accompanied by all documents, in form and substance reasonably satisfactory to Parent and the Exchange Agent, required to evidence and effect such transfer of Company Common Stock and to evidence that any applicable stock transfer taxes have been paid. There shall be no transfers on the transfer records of the Company, at or after the Effective Time, of shares of Company Common Stock which were outstanding immediately prior to the Effective Time. (f) Notwithstanding any other provisions of this Agreement, no dividends or other distributions declared after the Effective Time on Parent Common Stock ("POST-CLOSING DIVIDENDS") shall be paid with respect to any shares of Company Common Stock represented by a Certificate until such Certificate is surrendered for exchange as provided herein. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of Post-Closing Dividends with a record date after the Effective Time theretofore payable with respect to such whole shares of Parent Common Stock and not paid, less the amount of any withholding taxes which may be required thereon ("SPECIFIED POST-CLOSING DIVIDENDS"), and (ii) at the appropriate payment date, the amount of Post-Closing Dividends with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Parent Common Stock, less the amount of any withholding taxes which may be required thereon. (g) Certificates surrendered for exchange by any person that is an "affiliate" of the Company for purposes of Rule 145(c) under the Securities Act of 1933, as amended (the "SECURITIES ACT"), shall not be exchanged until Parent has received a written agreement from such person as provided in Section 5.11. (h) One year after the Effective Time, the Exchange Agent shall deliver to the Surviving Corporation any portion of the Exchange Fund (including the proceeds of any investments thereof and any shares of Parent Common Stock) that remains unclaimed by the former stockholders of the Company. Thereafter, former stockholders of the Company that have not surrendered their Certificates for exchange shall look to the Surviving Corporation for delivery of Merger Certificates, cash in lieu of fractional shares and unpaid Post-Closing Dividends which such former stockholder is entitled to receive in respect of the Company Common Stock represented by the theretofore unsurrendered Certificates, in each case, without any interest thereon. (i) None of Parent, the Company, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former stockholder of the Company for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. 2.4. LOST CERTIFICATES. In the event any Certificate shall have been lost, stolen or destroyed, upon the making and delivery of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Parent Common Stock and cash deliverable in respect thereof pursuant to this Agreement. 2.5. ADJUSTMENT OF EXCHANGE RATIO. In the event that, subsequent to the date of this Agreement but prior to the Effective Time, the outstanding shares of Parent Common Stock shall have been changed into a different number of shares or a different class as a result of a stock split, reverse stock split, stock dividend, subdivision, reclassification, combination, exchange, recapitalization or other similar transaction, the Exchange Ratio shall be appropriately adjusted.

AGREEMENTS. Between the date hereof and the Closing Date, neither Parent nor the Company shall enter into any agreement which Parent or the Company, as the case may be, knows or has reason to know is reasonably likely to cause any major customer of Parent or the Company (or their respective subsidiaries) to terminate any material contracts, agreements or other obligations that exist between that customer on the one hand, and Parent, the Company (or Parent and the Company following the Merger) or any subsidiary of either, on the other hand and Parent and the Company shall take all reasonable action appropriate to an effort to avoid such termination. 5.15. TAKEOVER STATUTE.

Moreover, in the event of termination of this Agreement pursuant to Section 7.3 or 7.4, nothing herein shall prejudice the ability of the nonbreaching party from seeking damages, after taking into account payment of the Termination Fee, if such fee has been paid, from any other party for any willful breach of this Agreement, including without limitation, attorneys' fees and the right to pursue any remedy at law or in equity. 7.6.
