Without limiting the generality of the foregoing, each of the LLCs, by executing this Joinder Agreement, is (a) making the representations and warranties set forth in Article III of the Stock Purchase Agreement as a Shareholder (provided that such representations and warranties are being made by each such LLC as of the date hereof, and provided further that in the case of the representation and warranty of each LLC pursuant to Section 3.1(a) of the Stock Purchase Agreement, such representation and warranty is being made by such LLC as of immediately prior to the Closing) and (b) agreeing to be bound by, and subject to, all of the covenants and agreements set forth in the Stock Purchase Agreement applicable to a Shareholder. Execution and delivery of this Joinder Agreement by each of the LLCs shall constitute execution and delivery by it of the Stock Purchase Agreement, without further action of any party. Each of the LLCs hereby acknowledges that the Stock Purchase Agreement provides for the escrow, in accordance with an escrow agreement as set forth in the Stock Purchase Agreement, of a portion of the proceeds otherwise payable by Buyer to each Shareholder in exchange for such Shareholder’s shares of Company Stock. Each of the LLCs hereby (i) appoints ▇▇▇▇▇ ▇▇▇▇▇▇▇ to serve as each such LLC’s agent in selling such LLC’s Company Stock to Buyer and (ii) grants ▇▇▇▇▇ ▇▇▇▇▇▇▇ an irrevocable power of attorney to sell such LLC’s Company Stock to Buyer pursuant to the terms of the Stock Purchase Agreement. Pursuant to Section 10.4 of the Stock Purchase Agreement, each of the LLCs further agrees that by becoming a Shareholder it will be deemed to irrevocably constitute and appoint ▇▇▇▇▇ ▇▇▇▇▇▇▇ as its true and lawful agent and attorney-in-fact with full powers of substitution, to act in the name, place and stead of such LLC with respect to the Stock Purchase Agreement and with respect to the transfer of such LLC’s Company Stock to Buyer pursuant to the Stock Purchase Agreement and the transactions contemplated thereby, and to do or refrain from doing all such acts and things, and to execute all such documents, as the Representative shall deem necessary or appropriate in connection with the Stock Purchase Agreement, the Ancillary Documents or any of the transactions contemplated thereby.

CSK represents and warrants to Buyer that it is a Person controlled by ▇▇▇▇▇ ▇▇▇▇▇▇▇ in which ▇▇▇▇▇ ▇▇▇▇▇▇▇ and his [wife and] children have at least a 90% economic beneficial interest. Each LLC other than CSK represents and warrants to Buyer that it is an “Other ▇▇▇▇▇▇▇ Entity” as defined in the Stock Purchase Agreement.

          Section 5. Contribution Percentage Notice; Limited Waivers. This Joinder Agreement constitutes a Contribution Percentage Notice pursuant to Section 6.17 of the Stock Purchase Agreement.

Each of the Former Shareholders hereby represents and warrants that the Restructurings, including without limitation the direct and indirect transfers of Company Stock from the Former Shareholders to the LLCs acquiring such Company Stock, as described in third “Whereas” clause above, do not (a) violate any Law or Order to which such Former Shareholder is subject, result in the creation or imposition of any Encumbrance upon the Company Stock formerly held of record or beneficially owned by such Former Shareholder, or require such Former Shareholder to give any notice to, make any filing with, or obtain any authorization, consent or approval of, any Person.

          Section 7. Further Assurances. At any time or from time to time after the date hereof, each LLC agrees to execute and deliver any further instruments or documents and take

such additional actions as the Company, the Representative or Buyer may reasonably request in order to evidence or effectuate its sale of Company Stock pursuant to the Stock Purchase Agreement and to otherwise carry out the intent of the parties under this Joinder Agreement.
