iii STOCK PURCHASE AGREEMENT THIS STOCK PURCHASE AGREEMENT (this "Agreement") is made as of the 5th day of October 2006, by and among WILLIAM G. KELLER AND THOMAS A. KELLER (each a "Stockholder", and together, the "Stockholders") and NATIONAL DENTEX CORPORATION, a Massachusetts corporation ("Buyer"). WITNESSETH: WHEREAS, Keller Group, Incorporated, a Missouri corporation (the "Company"), operates a dental laboratory business at 160 Larkin Williams Industrial Court, Fenton, MO 63026 and at 1700 Cargo Court, Louisville, KY 40299, and a sales office at 1420 Northwest Vivion Road, Suite 108, Kansas City, MO 64118-4555; WHEREAS, the Stockholders collectively own of record all of the issued and outstanding Shares (as defined in Section 4(f)) of the Common Stock (as defined in Section 4(f)) of the Company, which Shares represent all of the issued and outstanding capital stock of the Company; and WHEREAS, the Stockholders desire to sell to Buyer, and Buyer desires to purchase from the Stockholders, the Shares upon the terms and conditions hereinafter set forth. NOW, THEREFORE, in consideration of the agreements and covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows: 1. Purchase and Sale of the Shares. Subject to the terms and conditions of this Agreement and in reliance upon the representations and warranties of the parties set forth herein, the Stockholders shall sell to Buyer, and Buyer shall purchase from the Stockholders, the Shares on the Closing Date (as defined in Section 3), for the consideration set forth in Section 2. 2. Consideration. (a) Purchase Price. The purchase price for the Shares (the "Purchase Price") shall be calculated and payable as follows: (i) At the Closing, Buyer shall pay Nineteen Million One Hundred Twenty-five Thousand Dollars ($19,125,000) by wire transfer (the "Closing Payment") to the Stockholders, which amount shall be allocated Fifty Percent (50%) to each Stockholder; and (ii) Buyer shall pay each Stockholder an amount (the "Deferred Payment"), subject to adjustment in accordance with Section 2(b), equal to forty-one 1 percent (41%) of the ordinary business income of such Stockholder from the Company as set forth in the Schedule K-1 (as hereinafter defined), line 1 less line 11 of such Schedule K-1 minus the $105,000 distributed by the Company during the current fiscal year of the Company to such Stockholder. The Deferred Payment shall be paid by Buyer to each Stockholder within thirty (30) days after the filing by the Company with the Internal Revenue Service of its final Form 1120S for the current fiscal year of the Company. The "Schedule K-1" means, with respect to each Stockholder, the final form K-1 issued by the Company to each Stockholder setting forth the ordinary income of such Stockholder from the Company for the current fiscal year of the Company. (b) Closing Balance Sheet. (i) On or prior to the Closing Date, the Stockholders and Buyer shall jointly prepare a pro forma consolidated balance sheet of the Company and its subsidiaries as of the Effective Date (as defined in Section 3) (the "Pro Forma Closing Balance Sheet"), in accordance with generally accepted accounting principles ("GAAP") consistently applied and compiled in accordance with the Standards for Accounting and Review Services issued by the American Institute of Certified Public Accountants (the "Standards"). (ii) Within sixty (60) days after the Effective Date, Buyer with the assistance of the Stockholders shall prepare a consolidated balance sheet of the Company and its subsidiaries as of the Effective Date (the "Closing Balance Sheet"), in accordance with GAAP and compiled in accordance with the Standards, Buyer shall, by notice, provide each Stockholder with the Closing Balance Sheet. Each Stockholder shall have a period of twenty (20) days after the notice from the Buyer within which to give notice to Buyer that he either (i) accepts the Closing Balance Sheet or (ii) disputes the Closing Balance Sheet, including a statement in reasonable detail of the disputed items. If a Stockholder fails to give notice to Buyer within such twenty (20) day period, he shall be deemed to have accepted the Closing Balance Sheet. If a Stockholder gives Buyer notice that he disputes the Closing Balance Sheet, then Buyer and the Stockholder(s) shall meet as soon as reasonably possible (but in any event within twenty (20) days after notice by the Stockholder(s)) and attempt, in good faith, to resolve the dispute. If the parties are unable to agree upon the Closing Balance Sheet, or any portion thereof, within fifteen (15) days after the parties have commenced resolution of the dispute, then the matter shall be submitted for resolution to a mutually agreeable certified public accounting firm (the "Independent Accountants"), whose determination shall be final and binding upon the parties, and whose fees shall be borne equally by the Stockholders and Buyer except, however, that if the Independent Accountants determine that the Closing Balance Sheet proposed by Buyer was correct in its entirety, then the Stockholders shall be solely responsible for the fees of the Independent Accountants; and if the Independent Accountants determine that the dispute in the Closing Balance Sheet 2 should be resolved in favor of the Stockholders in its entirety, then Buyer shall be solely responsible for the fees of the Independent Accountants. 3. Closing. The closing of the purchase and sale of the Shares (the "Closing") shall take place on October 5, 2006 (the "Closing Date") and shall be deemed to have been effective as of opening of business on October 2, 2006 (the "Effective Date"). 4.

If a Stockholder acknowledges to Buyer in writing that such Third-Party Claim is subject to the indemnity set forth in Section 9(a), the Stockholder shall have the right to defend or settle any such Third-Party Claim, at his sole expense, on his own behalf and with counsel of his own choosing, which counsel shall be reasonably satisfactory to Buyer. In such defense or settlement of any Third-Party Claim, Buyer shall cooperate with and assist the Stockholder as is reasonable and may participate therein with its own counsel at its sole expense, and Buyer's written consent shall be a requirement to any settlement and disposition thereof, which consent shall not be unreasonably withheld or delayed, provided that in any such settlement or disposition, Buyer shall not be liable for any amounts under such settlement or disposition and such settlement or disposition shall contain a complete release of Buyer from any liability. Failure by Buyer to give notice within a reasonable period of time shall not constitute a defense, in whole or in part, to any claim for indemnification by Buyer, except only to the extent that such failure by Buyer shall result in a material prejudice to the Stockholders. If a Stockholder does not notify Buyer within ten (10) days after receipt of Buyer's written notice of a Third-Party Claim that the Stockholder intends to undertake the defense thereof, and that such claim is subject to the indemnity set forth in Section 9(a), or if after undertaking such defense the Stockholder fails to pursue such defense in a prudent manner, then Buyer shall have the right to contest, settle or compromise such Third-Party Claim, and the Stockholders, jointly and severally, shall indemnify Buyer for the full amount of all Losses paid or suffered by Buyer in respect thereof. So long as a Stockholder has given Buyer timely notice that the Stockholder will undertake the defense of the Third-Party Claim, and is defending such Third-Party Claim in good faith, Buyer shall not pay or settle any such Third-Party Claim without the consent of the defending Stockholder, which shall not be unreasonably withheld or delayed, unless the continued unresolved existence of 25 such Third-Party Claim may have, in Buyer's reasonable judgment, a material adverse effect on the business of Buyer, the Company or any Subsidiary, or on Buyer, the Company or the any Subsidiary (including, but not limited to, any attachment, lien or other encumbrance on Buyer, the Company or any Subsidiary, or their assets, any refusal of any suppliers or customers of Buyer, the Company or any Subsidiary to do business with Buyer, the Company or any Subsidiary while such Third-Party Claim is pending, or if the continued unresolved existence of any such Third-Party Claim would constitute a default or an event of default under any loan or other credit facilities to which Buyer, the Company or any Subsidiary is a party), in any of which cases Buyer shall have the right to settle such Third-Party Claim, and the Stockholders, jointly and severally, shall indemnify Buyer for the full amount of all Losses paid or suffered by Buyer, the Company and the Subsidiaries in respect thereof. (d) Cumulative Remedies. Except as expressly provided herein, the remedies provided to Buyer, the Company and the Subsidiaries in this Section 9 shall be cumulative and shall not preclude the assertion by Buyer of any other rights or the seeking of any other remedies against the Stockholders. 10. Indemnification by Buyer. (a) Indemnity. Buyer shall indemnify, defend and hold the Stockholders harmless from and against any and all Losses suffered by the Stockholders resulting from (i) any breach of any representation or warranty, covenant, agreement or obligation on the part of Buyer under this Agreement, any schedule to this Agreement or under any agreement executed in connection herewith; (ii) any misrepresentation in or omission from any certificate or other instrument furnished to the Stockholders pursuant hereto or in connection herewith; and (iii) any claims for brokers' or finders' fees or compensation in connection with the transactions provided for by this Agreement by any person, firm, corporation or other entity claiming a right to fees or compensation by reason of having been engaged by or having served Buyer. (b) Payment of Losses. Subject to the provisions of Section 10(c), the Stockholders shall be reimbursed by Buyer on demand for any Loss suffered by the Stockholders with respect to any liability or claim to which the indemnity set forth in Section 10(a) relates. (c) Third-Party Claims. Should any Third-Party Claim be made against the Stockholders with respect to any matter to which the indemnity set forth in Section 10(a) relates, then the Stockholders shall promptly give Buyer written notice of any such Third-Party Claim and Buyer shall have the right to defend or settle any such Third-Party Claim, at its sole expense, on its own behalf and with counsel of its own choosing, which counsel shall be reasonably satisfactory to the Stockholders. The Stockholders agree that Posternak Blankstein & Lund LLP is satisfactory. In such defense or settlement of any claim, the Stockholders shall cooperate with and assist Buyer to the maximum extent reasonably possible and may participate therein with his or her own counsel at his or her own expense, 26 and the Stockholders' written consent shall be a requirement to any settlement and disposition thereof, which consent shall not be unreasonably withheld or delayed. Failure by the Stockholders to give notice within a reasonable period of time shall not constitute a defense, in whole or in part, to any claim for indemnification by the Stockholders, except only to the extent that such failure by the Stockholders shall result in a material prejudice to Buyer. If Buyer does not notify the Stockholders within ten (10) days after receipt of the Stockholders' written notice of a Third-Party Claim that Buyer intends to undertake the defense thereof, and that such claim is subject to the indemnity set forth in Section 10(a), or if after undertaking such defense Buyer fails to pursue such defense in a prudent manner, then the Stockholders shall have the right to contest, settle or compromise the claim and Buyer shall indemnify the Stockholders for the full amount of all Losses paid or suffered by the Stockholders in respect thereof. Notwithstanding the foregoing, so long as Buyer is contesting any such Third Party Claim in good faith, the Stockholders shall not have the right to pay or settle any such claim without the prior written consent of Buyer. (d) Cumulative Remedies. Except as expressly provided herein, the remedies provided to the Stockholders in this Section 10 shall be cumulative and shall not preclude the assertion by the Stockholders of any other rights or the seeking of any other remedies against Buyer. 11. Press Releases. Because Buyer is a publicly-traded company, it is subject to strict guidelines regarding its disclosure of the transaction contemplated by this Agreement, and accordingly, the Stockholders agree that they will not release, and shall not permit any person or entity to release, any press releases or other similar announcements without Buyer's prior approval thereof. 12. Covenants and Agreements of the Stockholders and Buyer. The Stockholders and Buyer agree as follows: (a) Tax Filing. The consummation of the transaction contemplated by this Agreement will be a disqualifying event and the Company's S Corporation election shall terminate as of the Effective Date. Buyer and the Stockholders agree that the Company's and the Subsidiaries' 2006 tax year shall be treated as two (2) tax years, the first of which ends on the close of business on the date immediately preceding the Effective Date (the "End Date") and the second of which begins on the Effective Date and ends on December 31, 2006. The Stockholders agree that they will cause the tax return for the period from January 1, 2006 to the End Date to be prepared and provided to Buyer, at Buyer's sole expense, for review and filing by Buyer in a timely manner consistent with the filing requirements under the Internal Revenue Code. Buyer agrees to provide to the Stockholders and their agents, all information available from the books of the Company, as reasonably requested by the Stockholders, for the preparation of that return. (b) Tax Proceedings. Buyer will have the right to represent the interests of the Company and any Subsidiary before any governmental authority with respect to any inquiry, assessment, proceeding or other similar event relating to any Tax filing or reporting 27 of the Company and any Subsidiaries and will have the right to control the defense, compromise or other resolution of any such matters, including responding to inquiries, filing tax returns and contesting, defending and resolving any assessment for additional Taxes or notice of Tax deficiency or other adjustment of Taxes. If the Stockholders would be required to indemnify Buyer, the Company or any Subsidiary pursuant to Section 9 with respect to such Tax matter then the Stockholders have the right (but not the duty) to participate in the defense of such Tax matter as provided in Section 9(c). 13.
