	NATIONAL DENTEX CORPORATION
	(Registrant)

May 13, 2010
	By: /s/ David L. Brown
	David L. Brown
	Chairman of the Board and Chief Executive Officer

~~On April 2, 2010, National Dentex Corporation, a Massachusetts corporation (the~~ ~~“Company”),~~ Exhibit ~~entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and~~Index among the Company, GDC Holdings, Inc., a Delaware corporation (“GDC”), and Royal Acquisition Corp., a Delaware corporation (“Merger Sub”). Merger Sub is an indirect wholly owned subsidiary of GDC and a direct wholly owed subsidiary of GeoDigm Corporation, a Minnesota corporation (“GeoDigm”). Pursuant to the terms of the Merger Agreement, Merger Sub will be merged with and into the Company, and as a result the Company will continue as the surviving corporation and a wholly owned subsidiary of GeoDigm (the “Merger”). GDC is controlled by a private equity investment fund associated with Welsh, Carson, Anderson & Stowe (“Welsh Carson”).

~~Pursuant to the Merger Agreement, at the effective time of the Merger, each issued and~~ ~~outstanding share of common stock of the Company (collectively, the “Common Stock”) will be~~ ~~canceled and extinguished and automatically converted into the right to receive $17~~ 99.001 Press ~~in cash~~Release, ~~without interest. All outstanding and unexercised options and other rights to acquire~~dated ~~Common~~ May ~~Stock under the Company’s equity incentive plans will become fully vested~~13, ~~and will be terminated and settled for a per share cash payment equal to the difference between $17~~2010.00 and the respective exercise price. The Company will terminate its employees’ stock purchase plan prior to the effective date and the options outstanding under the employees’ stock purchase plan will not be converted into the right to receive the per share merger consideration.

The Merger Agreement contains a provision under which the Company may solicit alternative acquisition proposals from the date of the Merger Agreement through May 12, 2010. After expiration of such “go-shop” period, the Company is subject to a “no-shop” restriction on its ability to solicit alternative acquisition proposals, provide information and engage in discussions with third parties. The no-shop provision is subject to a “fiduciary-out” provision that allows the Company under certain circumstances to provide information and participate in discussions at any time with respect to unsolicited alternative acquisition proposals.

The Merger Agreement contains certain termination rights for both the Company and GDC. The Merger Agreement provides that, upon termination under specified circumstances, the Company would be required to pay GDC a termination fee of either $4.15 million or $3.15 million, depending on the circumstances of the termination and, under certain circumstances, to reimburse GDC for an amount not to exceed $2 million for transaction expenses incurred by GDC and its affiliates. The Company’s reimbursement of GDC’s expenses would reduce the amount of any required termination fee payable that becomes payable by the Company.

The Company and GDC are parties to an equity commitment letter (the “Equity Commitment Letter”) with Welsh, Carson, Anderson & Stowe XI, L.P. (the “Sponsor”), and the sole stockholder of GDC. Under the terms of the Equity Commitment Letter, the Sponsor has committed to make cash contributions to GDC to fully finance the Merger and the other transactions contemplated thereby up to a maximum of $139 million (“Merger Consideration Amount”). The consummation of the Merger is not subject to a financing condition, but is subject to customary conditions to closing, including the approval of the Company’s shareholders and receipt of requisite antitrust approvals. The affirmative vote of the majority of the Company’s outstanding Common Stock is required to approve the Merger.

In the event of a breach of the Merger Agreement by GDC or Merger Sub, or the Equity Commitment Letter by Sponsor, the Company’s sole remedy is to seek specific performance (or, if the court declines to award specific performance, to recover money damages), against GDC in order to enforce GDC’s obligations under the Merger Agreement, including to consummate the Merger, and against Sponsor in order to enforce Sponsor’s obligations under the Equity Commitment Letter, including Sponsor’s commitment to provide the cash contributions to GDC to consummate the Merger or satisfy GDC or Merger Sub’s liability for any breaches by them of the Merger Agreement, in all events not to exceed the aggregate Merger Consideration Amount.

The foregoing description of the Merger Agreement is only a summary, does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Board of Directors of the Company (the “Board of Directors”) has unanimously approved and adopted the Merger Agreement. BBT Capital Markets (“BBT Capital”) served as financial advisor to the Board of Directors and Signal Hill Capital Group LLC (“Signal Hill”) provided a fairness opinion to the Board of Directors.

On April 5, 2010, the Company issued a press release announcing that it had entered into the Merger Agreement. A copy of the press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.

The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the Company. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement and as of specified dates, were solely for the benefit of the parties to the Merger Agreement, and may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Merger Agreement. The representations and warranties may have been made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company, GDC or Merger Sub or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.
