          (a) Such Purchaser has full power and authority to enter into this Agreement and this Agreement constitutes a valid and legally binding obligation of such Purchaser, enforceable against such Purchaser in accordance with its terms, subject to the effects of bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditor’s rights generally, and general equitable principles (whether considered in a proceeding in equity or at law).

          (b) If the Purchaser is a corporation, partnership, limited liability company, trust, or other entity, it represents that: (i) it is duly organized, validly existing and in good standing in its jurisdiction of incorporation or organization and has all the requisite power and authority to purchase the Securities as provided herein, and (ii) such investment has been duly authorized by all necessary action on behalf of the Purchaser.

          (c) If the Purchaser is purchasing the Securities in a representative or fiduciary capacity, the representations and warranties contained herein (and in any other written statement or document delivered to the Corporation in connection herewith) shall be deemed to have been made on behalf of the person or persons for whom such Securities are being purchased.

          (d) Such Purchaser is purchasing the Securities for Purchaser’s own account and not with a view to or for sale in connection with any distribution thereof in a transaction that would violate or cause a violation of the Securities Act or the securities laws of any state or any other applicable jurisdiction. The Purchaser has no present intention of selling the Securities, granting any participation interest in the Securities or otherwise distributing the Securities, in each case in violation of the Securities Act. If the Purchaser is an entity, the Purchaser has not been organized solely for the purpose of acquiring the Securities. Purchaser is not a broker dealer registered with the SEC under the Exchange Act or an entity engaged in a business that would require it to be so registered.

          (e) Such Purchaser is an “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act and understands and agrees that the offer and sale of the Securities to Purchasers hereunder have not been registered under the Securities Act or any state securities law in reliance on the availability of an exemption from such registration requirements based on the accuracy of the Purchaser’s representations in this Section 4.2.

          (f) In the normal course of such Purchaser’s business or affairs, Purchaser invests in or purchases securities similar to the Securities and has such knowledge and

experience in financial and business matters as to be capable of evaluating the merits and risks of purchasing the Securities. Purchaser has received and has carefully reviewed the Disclosure Materials and understands the information contained therein. Purchaser understands that the Disclosure Materials contain certain “forward-looking” information regarding the Corporation and its business, and that the Corporation’s ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Purchaser has had access to such financial and other information concerning the Corporation and its Subsidiaries as Purchaser deemed necessary or desirable in making a decision to purchase the Securities, including an opportunity to ask questions and receive answers from officers of the Corporation and to obtain additional information (to the extent the Corporation possessed such information or could acquire it without unreasonable effort or expense) necessary to verify the accuracy of any information furnished to Purchaser or to which Purchaser had access.

          (g) Such Purchaser is not relying on the Corporation or any of its affiliates with respect to an analysis or consideration of the terms of or economic considerations relating to an investment in the Securities. In regard to such considerations and analysis, the Purchaser has relied on the advice of, or has consulted with, only his, her or its own advisors, other than those advisors of the undersigned affiliated with the Corporation or any of its affiliates.

          (h) Such Purchaser acknowledges and is aware that there are substantial restrictions on the transferability of the Securities. Purchaser understands that the Securities have not been registered under the Securities Act and are “restricted securities” within the meaning of Rule 144 and may not be sold, transferred, or otherwise disposed of without registration under the Securities Act or an exemption therefrom. Furthermore, Purchaser acknowledges that each certificate evidencing the Securities purchased hereunder will bear a legend substantially to the effect set forth below, and each Purchaser covenants that, except to the extent such restrictions are waived by the Corporation, such Purchaser shall not transfer the shares represented by any such certificate without complying with the restrictions on transfer described in the legend endorsed on such certificate:

     THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED ABSENT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR COMPLIANCE WITH RULE 144 PROMULGATED UNDER SUCH ACT, OR UNLESS THE CORPORATION HAS RECEIVED AN OPINION OF COUNSEL, SATISFACTORY TO THE CORPORATION AND ITS COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT SUCH REGISTRATION IS NOT REQUIRED. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

     Purchaser understands that except as provided in the Registration Rights Agreement, Purchaser has no right to require that the Securities be registered under the Securities Act.

     If the Securities become eligible for sale pursuant to Rule 144(b)(1) or any similar or successor provision, the Corporation shall within seven days, upon the request of the holder of such Securities pursuant to this Agreement, remove the legend set forth in Section 4.2(h) from the certificates for such Securities. In addition, if in connection with any transfer a holder of the Securities pursuant to this Agreement delivers to the Corporation an opinion of counsel which (to

the Corporation’s reasonable satisfaction) is knowledgeable in securities law matters to the effect that no subsequent transfer of such Securities shall require registration under the Securities Act, then the Corporation promptly upon such contemplated transfer shall deliver new certificates for such Securities which do not bear the Securities Act legend set forth in Section 4.2(h).

          (i) Each Purchaser represents and warrants that it is not required to obtain, prepare or file any authorization, approval, consent, filing or registration with any federal Governmental Authority in order to consummate the Transactions at the Closing Date.

          (j) The Purchaser did not learn of the investment in the Securities by means of any formal general or public solicitation or general advertising or publicly disseminated advertisements or sales literature, including (i) any advertisement, articles, notices or other communication published in any newspaper, magazine or similar media, or broadcast over television or radio, or (ii) any seminar or meeting to which such Purchaser was invited by any of the foregoing means of communications.

     5. ADDITIONAL AGREEMENTS

     5.1 Availability of Information. The Corporation agrees to use its best efforts to timely file all periodic reports required under Sections 13(a), 15(d) and 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and to maintain the listing of its Common Stock on the Nasdaq Global Select Market or other similar stock exchange following the Closing Date for so long as is required under Rule 144 for the sale of the Shares.

     5.2 Form D and Blue Sky. The Corporation agrees to file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof to each Purchaser promptly after such filing. The Corporation, on or before the Closing Date, shall take such action as the Corporation shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for sale to the Purchasers at the Closing pursuant to this Agreement under applicable securities or “Blue Sky” laws of the states of the United States (or to obtain an exemption from such qualification), and shall provide evidence of any such action so taken to the Purchasers on or prior to the Closing Date. The Corporation shall make all filings and reports relating to the offer and sale of the Securities required under applicable securities or “Blue Sky” laws of the states of the United States following the Closing Date.

     5.3 Regulatory Matters. Each of the Corporation and each Purchaser agree to use reasonable efforts to take all actions and to do all things necessary, proper or advisable to obtain any authorizations, consents, orders and approvals of all Governmental Authorities necessary for the Corporation to sell the Securities on the Closing Date on terms consistent with the terms set forth in this Agreement.

     5.4 Publicity. Each Purchaser acknowledges that the Corporation will publicly announce the entering into this Agreement and the completion of the Transactions as soon as practicable following the date hereof and in any event not later than the second business day after the Closing Date; provided, however, that the Corporation shall not specifically name the Purchasers in a press release without the prior consent of such Purchaser. Notwithstanding the preceding paragraph, each Purchaser hereby agrees that the Corporation may specifically name Purchaser as one of the Purchasers of Securities in its periodic reports filed under the Exchange Act as required by the rules and regulations of the Exchange Act and as otherwise required in the registration statement to be filed pursuant to the Registration Rights Agreement.

     5.5 Subsequent Sales of Common Stock. The Corporation shall not take any action or omit to take any action which would cause the Transactions or any portion thereof to require a vote of the Corporation’s stockholders.

     6. MISCELLANEOUS

     6.1 Survival of Representations and Warranties. All statements contained in any officers’ certificates delivered by or on behalf of the Corporation or its Subsidiaries pursuant to this Agreement or in connection with the Transactions contemplated hereby will be deemed representations or warranties of the Corporation under this Agreement. All representations and warranties contained in this Agreement made by or on behalf of the Corporation or the Purchasers will survive the execution and delivery of this Agreement, any investigation at any time made by or on behalf of the Corporation or the Purchasers, and the sale and purchase of the Securities under this Agreement, and, except for representations and warranties set forth in

Section 4.1(g), (h), (i), (j) and Section 4.2(i) shall expire on the first anniversary of the Closing Date.

     6.2 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of and be enforceable by or against the respective successors and assigns of the parties hereto.

     6.3 Notices. All written communications provided for herein are required to be sent by U.S. Certified Mail or recognized overnight delivery service (with charges prepaid) and (i) if to a Purchaser, addressed to such Purchaser at the address as specified for such communications in the Signature Page, or at such other address as such Purchaser may have specified to the Corporation in writing, and (ii) if to the Corporation, addressed to it at:

Pinnacle Financial Partners, Inc.
211 Commerce Street
Suite 300
Nashville, TN 37201
Attn: Terry Turner, President and Chief Executive Officer

or at such other address as the Corporation may have specified to the Purchasers in writing. Notices under this Section 6.3 shall be deemed given only when actually received.

     6.4 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of Maryland, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Maryland or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Maryland.

     6.5 Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

     6.6 Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

     6.7 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

     6.8 Expenses. Each Purchaser and the Corporation shall bear all expenses incurred by it in connection with the Agreement and the Transactions contemplated hereby.

     6.9 Construction. Each agreement contained herein shall be construed (absent express provision to the contrary) as being independent of each other agreement contained herein, so that compliance with any one agreement shall not (absent such an express contrary provision) be deemed to excuse compliance with any other agreement. Where any provision herein refers to action to be taken by any person or entity, or which such person or entity is prohibited from

taking, such provision shall be applicable whether such action is taken directly or indirectly by such person or entity.

     6.10 Entire Agreement; Amendments. This Agreement supersedes all other prior oral or written agreements between the Purchasers, the Corporation, their affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Agreement and the instruments referenced herein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Corporation nor any Purchaser makes any representation, warranty, covenant or undertaking with respect to such matters. No provision of this Agreement may be amended other than by an instrument in writing signed by i) the Corporation; and iii) the holders of Shares representing at least a majority of the amount of the Shares then outstanding, or, if prior to the Closing Date, the Purchasers listed on the Signature Page as being obligated to purchase at least a majority of the amount of the Shares. No provision hereof may be waived other than by an instrument in writing signed by the party against whom enforcement is sought. No such amendment shall be effective to the extent that it applies to less than all of the holders of the Securities then outstanding. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration also is offered to all of the parties to the Transaction Documents, including holders of the Securities. The Corporation has not, directly or indirectly, made any agreements with any Purchasers relating to the terms or conditions of the transactions contemplated by the Transaction Documents except as set forth in the Transaction Documents. Without limiting the foregoing, the Corporation confirms that, except as set forth in this Agreement, no Purchaser has made any commitment or promise or has any other obligation to provide any financing to the Corporation or otherwise.

     6.11 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns, including any purchasers of the Securities. The Corporation shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the holders of Shares representing at least a majority of the amount of the Shares then outstanding. A Purchaser may assign some or all of its rights hereunder without the consent of the Corporation, in which event such assignee shall be deemed to be a Purchaser hereunder with respect to such assigned rights.

     6.12 No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

     6.13 Indemnification.

          (a) In consideration of each Purchaser’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Corporation’s other obligations under the Transaction Documents, the Corporation shall defend, protect, indemnify and hold harmless each Purchaser and all of their stockholders, partners, members, officers, directors, employees and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Corporation in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Corporation contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Corporation) and arising out of or resulting from any misrepresentation or breach of any representation or warranty made by the Corporation in the Transaction Documents, or any covenant, agreement or obligation of the Corporation contained in the Transaction Documents, or any other certificate, instrument or document contemplated hereby or thereby. To the extent that the foregoing undertaking by the Corporation may be unenforceable for any reason, the Corporation shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

          (b) Promptly after receipt by an Indemnitee under this Section 6.13 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving an Indemnified Liability, such Indemnitee shall, if a claim for indemnification in respect thereof is to be made against any indemnifying party under this Section 6.13, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel with the fees and expenses of not more than one counsel for such Indemnitee to be paid by the indemnifying party, if, in the reasonable opinion of counsel to the Indemnitee, the representation by such counsel of the Indemnitee and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnitee and the indemnifying party. Legal counsel referred to in the immediately preceding sentence shall be selected by the Purchasers holding at least a majority of the Securities issued and issuable hereunder. The Indemnitee shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or Indemnified Liabilities by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnitee that relates to such action or Indemnified Liabilities. The indemnifying party shall keep the Indemnitee fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any

action, claim or proceeding effected without its prior written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement or other compromise which (i) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a release from all liability in respect to such Indemnified Liabilities or litigation, (ii) requires any admission of wrongdoing by such Indemnitee, or (iii) obligates or requires an Indemnitee to take, or refrain from taking, any action. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnitee under this Section 6.13, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

          (c) The indemnification required by this Section 6.13 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Liabilities are incurred.

          (d) The indemnity agreements contained herein shall be in addition to (x) any cause of action or similar right of the Indemnitee against the indemnifying party or others, and (y) any liabilities the indemnifying party may be subject to pursuant to the law.

     6.14 No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

     6.15 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Corporation does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Corporation, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights

     6.16 Payment Set Aside. To the extent that the Corporation makes a payment or payments to the Purchasers hereunder or pursuant to any of the other Transaction Documents or the Purchasers enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Corporation, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, foreign, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

     6.17 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents and the Corporation acknowledges that the Purchasers are not acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.
