ARTICLE 8. MISCELLANEOUS PROVISIONS

8.1 Expenses. Whether or not the Transaction is consummated, each party shall pay it own costs and expenses in connection with this Agreement and the Transaction (including the fees and expenses of its advisers, accountants and legal counsel).

8.2 Interpretation. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed, as the context indicates, to be followed by the words “but (is/are) not limited to.”

8.3 Further Assurances. Each party agrees (a) to furnish upon request to each other party such further information, (b) to execute and deliver to each other party such other documents consistent herewith, and (c) to do such other acts and things, all as another party may reasonably request for the purpose of carrying out the intent of this Agreement and the Transaction.

8.4 Attorney Representation and Waiver of Potential Conflict of Interest.

(a) Existing Member and the Company have been, and presently are, represented by the law firm of Miltner, Polk & Menck in this transaction, in the preparation of this Agreement, and in the preparation of an Amended and Restated Operating Agreement. Existing Member, New Member, and the Company hereby acknowledge that the law firm of Miltner, Polk & Menck has acted solely as the attorneys for Existing Member and the Company, but has not acted as the attorneys for, or otherwise represented, New Member or any other interested party. New Member further acknowledges that New Member did not rely on any legal advice from Miltner, Polk & Menck related to this Transaction and said agreements, and that New Member did not rely on Miltner, Polk & Menck for any disclosures that Existing Member and the Company are obligated to make under this Agreement, but rather relied solely on Existing Member and the Company to make all required disclosures, and communicated directly with Existing Member and the Company as to all of New Member’s due diligence, investigations, and disclosures prior to the Closing of the transaction. Existing Member, New Member, and the Company hereby consent to such representation by Miltner, Polk & Menck, APC, of the Existing Member and the Company, notwithstanding the fact that Miltner, Polk & Menck, APC may have also represented Camden Street Partners, LLC and its principal Steven Sheiner on other matters (which separate representation may have provided Miltner, Polk & Menck, APC with confidential information relating to Existing Member or its principal which may not have been disclosed to New Member, or which may have otherwise influenced the exercise of judgment by Miltner, Polk & Menck, APC).

(b) Existing Member, New Member and the Company hereby acknowledge that Company’s continued representation by Miltner, Polk & Menck, APC, after the Closing of this Transaction, creates a potential conflict of interest in that Miltner, Polk & Menck, APC, has represented, and may continue to represent, Member Camden Street Partners, LLC and its principal Steven Sheiner, and in that Miltner, Polk & Menck, APC does not represent, and will not become the attorneys for New Member when New Member becomes a minority Member of the Company. In the event of an actual conflict of interest among Existing Member, New Member and the Company after the Closing (for example, in any dispute among Existing Member and New Member related to the operation or dissolution of the Company), it may become necessary for Miltner, Polk & Menck, APC to withdraw as counsel to the Company and, potentially, to also withdraw as counsel to Camden to avoid such actual conflict of interest.

No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.
