ARTICLE III

Merger Consideration; Surrender of Certificates

3.01 Merger Consideration.

At the Effective Time, by virtue of the Parent Merger and without any action on the part of the holder thereof :

- 8 -

(a) Conversion of CNC Common Shares. Subject to Sections 3.03 and 3.04, and except as otherwise provided by paragraphs (b), (c), and (d) of this Section 3.01, each CNC Common Share issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, at the election of the holder thereof, the following:

(i) 0.761 NB&T Common Shares (the “Per Share Stock Consideration”);

(ii) cash in the amount of $11.41(the “Per Share Cash Consideration”); or

(iii) a combination of such NB&T Common Shares and cash.

provided, however, that any CNC Common Shares with respect to which the holder thereof holds of record 1,500 or fewer CNC Common Shares of record as of the Election Deadline (“Mandatory Cash Shares”), shall be converted into the right to receive the Per Share Cash Consideration, and no such Mandatory Cash Shares shall be converted into the right to receive the Per Share Stock Consideration, subject to the Aggregate Cash Consideration limitation set forth in paragraph (b).

(b) Aggregate Consideration.

(i) The “Aggregate Cash Consideration” for purposes of this Agreement shall be an amount equal to the Per Share Cash Consideration multiplied by 50% of the number of CNC Common Shares (excluding any of CNC’s Treasury Shares or CNC Common Shares owned by NB&T) outstanding as of the date hereof.

(ii) The “Aggregate Stock Consideration” for purposes of this Agreement shall be a number of NB&T Common Shares equal to 0.761 NB&T Common Shares multiplied by 50% of the number of CNC Common Shares (excluding any of CNC’s Treasury Shares or CNC Common Shares owned by NB&T) outstanding as of the date hereof.

(iii) If the number of CNC Common Shares issued and outstanding immediately prior to the Effective Time exceeds the number of CNC Common Shares issued and outstanding as of the date hereof, the Aggregate Stock Consideration and the Aggregate Cash Consideration will not be adjusted as a result of such excess, though appropriate adjustments will be made to the Per Share Stock Consideration and the Per Share Cash Consideration (as well as the Adjusted Per Share Cash Consideration and Adjusted Per Share Stock Consideration, in each case as defined below, if applicable).

(c) Adjustment for Change in Book Value. Subject to Section 3.01(b)(iii), in the event that, at the last day of the month immediately preceding the month in which the Effective Date occurs, CNC’s tangible net worth, excluding Accumulated Other Comprehensive Income, excluding the effect of an aggregate amount of up to $300,000 of legal, accounting and investment adviser fees and costs incurred or accrued by CNC or CNC Bank in connection with the Merger and this Agreement between March 31, 2009, and the last day of the month immediately preceding the month in which the Effective Date occurs (including the contingent

- 9 -

fee payable to CNC’s investment adviser upon the effectiveness of the Parent Merger), excluding any reserves requested by NB&T in writing in order to conform to NB&T’s policies and practices, and excluding the amount paid by CNC or CNC Bank for the D&O Policy required by Section 6.20(b), all as calculated in accordance with generally accepted accounting principles and in a manner consistent with CNC’s Financial Statements (the “Closing Consolidated Book Value”), is less than $8,000,000, the Per Share Cash Consideration and the Per Share Stock Consideration shall be reduced.

(i) The reduced Per Share Cash Consideration shall equal the product of (a) the quotient of (I) $7,125,000 less the difference between (A) $8,000,000 and (B) the Closing Consolidated Book Value, divided by (II) $7,125,000 (rounded to the nearest fourth decimal place), multiplied by (b) $11.41 (rounded to the nearest cent) (the “Adjusted Per Share Cash Consideration”). For example, assuming the Closing Consolidated Book Value were $7,500,000, the Adjusted Per Share Cash Consideration would be:


$7,125,000 - ($8,000,000 - $7,500,000)
$7,125,000		x $11.41 = $10.61

(ii) The reduced Per Share Stock Consideration shall equal the product of (a) the quotient of (I) 7,125,000 less the difference between (A) 8,000,000 and (B) the Closing Consolidated Book Value, divided by (II) 7,125,000 (rounded to the nearest fourth decimal place), multiplied by (b) 0.761 (rounded to the nearest third decimal place) (the “Adjusted Per Share Stock Consideration”).

Wherever this Agreement refers to the “Per Share Cash Consideration” or the “Per Share Stock Consideration,” such terms shall refer to the Adjusted Per Share Cash Consideration and the Adjusted Per Share Stock Consideration if such an adjustment is required by this Subsection (c).

(d) Adjustment for Insurance Proceeds. In the event that (i) CNC Bank receives after the date of this Agreement and before the Effective Date payment from its Community Bank Bond insurer for claims disclosed in the CNC Disclosure Schedule submitted by CNC Bank prior to the date of this Agreement, and (ii) the Closing Consolidated Book Value, calculated in accordance with Section 3.01(c), adjusted to include, without duplication, the receipt of the insurance payment, net of Taxes (including, without limitation, any income Taxes resulting from the receipt or accrual of such payment) and direct expenses incurred in connection with collection of such payment (the “Net Insurance Payment”), exceeds $8,000,000, then each CNC shareholder as of the Effective Time shall receive a pro rata cash payment in addition to the Per Share Cash Consideration and the Per Share Stock Consideration such shareholder would otherwise receive pursuant to this Agreement. The amount of such additional cash payment per share (the “Per Share Insurance Payment”) shall equal the quotient of (a) the least of (1) $1,300,000, (2) the amount of the Net Insurance Payment or (3) the amount by which the Closing Consolidated Book Value, calculated in accordance with Section 3.01(c) and adjusted to include, without duplication, the receipt of the Net Insurance Payment, exceeds $8,000,000, divided by (b) 624,459 (rounded to the nearest cent). For example, if CNC Bank were to receive $100,000 for its claims and incur Taxes and direct expenses in connection with the collection of

- 10 -

such claim in the amount of $50,000, and the Closing Consolidated Book Value, after recording the receipt of such net $50,000 payment, equaled $8,030,000, then the Per Share Insurance Payment would be:

($8,030,000 - $8,000,000) ÷ 624,459 = $.05

As another example, if CNC Bank were to receive $100,000 for its claims, incur $40,000 of Taxes and direct expenses in connection with collection of such payment, and the Closing Consolidated Book Value, after recording the receipt of such net $60,000 payment, equaled $8,200,000, then the Per Share Insurance Payment would be:

$60,000 ÷ 624,459 = $.10

(e) Treasury Shares. All Treasury Shares shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor.

(f) Outstanding NB&T Common Shares. Each NB&T Common Share issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and unaffected by the Merger.

3.02 Rights as Shareholders; Share Transfers. At the Effective Time, holders of CNC Common Shares shall cease to be, and shall have no rights as, shareholders of CNC, other than (a) to receive any dividend or other distribution with respect to such CNC Common Shares with a record date occurring prior to the Effective Time, (b) to receive the consideration provided under this Article III, and (c) appraisal rights in the case of Dissenting Shares. After the Effective Time, there shall be no transfers on the stock transfer books of CNC or the Surviving Corporation of any CNC Common Shares.

3.03 Election and Exchange and Payment Procedures.

(a) Exchange Agent. NB&T’s transfer agent will act as agent (the “Exchange Agent”) for purposes of conducting the election procedure and the exchange and payment procedures as described in this Section 3.03.

(b) Election Procedure. No later than three business days following the Effective Time, NB&T shall cause the Exchange Agent to mail or make available to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented issued and outstanding CNC Common Shares (“Old Certificates”): (i) a notice and letter of transmittal, specifying that delivery shall be effected and risk of loss and title to the Old Certificates shall pass only upon proper delivery of such certificates to the Exchange Agent and advising such holder of the effectiveness of the Parent Merger and the procedure for surrendering to the Exchange Agent the Old Certificates in exchange for the consideration set forth in Section 3.01, and (ii) an election form in such form as NB&T and CNC shall mutually agree (the “Election Form”). Each Election Form shall permit the holder (or in the case of nominee record holders, the beneficial owner through proper instructions and documentation) (i) to elect to receive NB&T Common Shares with respect to all of such holder’s CNC Common Shares, (ii) to elect to receive cash with respect to all of such holder’s CNC Common Shares, (iii) to elect to

- 11 -

receive cash with respect to some of such holder’s CNC Common Shares and to receive NB&T Common Shares with respect to such holder’s remaining CNC Common Shares, or (iv) to indicate that such holder makes no such election with respect to such holder’s CNC Common Shares (“No Election Shares”); provided, however, that each holder of Mandatory Cash Shares shall be permitted to elect only to receive cash with respect to such holder’s Mandatory Cash Shares. Any CNC Common Shares with respect to which the holder has elected to receive cash (including Mandatory Cash Shares) are hereinafter referred to as “Cash Election Shares,” and any CNC Common Shares with respect to which the holder has elected to receive NB&T Common Shares are hereinafter referred to as “Stock Election Shares.” Any CNC Common Shares with respect to which the holder thereof shall not, as of the Election Deadline, have made an election by submission to the Exchange Agent of an effective, properly completed Election Form shall be deemed to be No Election Shares. Any Dissenting Shares shall be deemed to be Cash Election Shares for purposes of the allocation provisions of Subsection (d) below, but in no event shall such shares be classified as Reallocated Stock Shares.

(c) Election Deadline; Revocation or Modification of Election. For purposes of this Agreement, the term “Election Deadline” shall mean 5:00 p.m. Eastern Time/4:00 p.m. Central Time, on the 30th day following, but not including, the date of mailing of the Election Form, or such other date upon which NB&T and CNC shall mutually agree prior to the Effective Time. Any election to receive cash, NB&T Common Shares or a combination of cash and NB&T Common Shares shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. Any submitted Election Form may be revoked or changed by written notice to the Exchange Agent only if such notice of revocation or change is actually received by the Exchange Agent prior to the Election Deadline. The Exchange Agent shall be required to make all determinations as to when any election, modification or revocation has been received and whether any such election, modification or revocation has been properly made.

(d) Reallocation of NB&T Common Shares and Cash. The Exchange Agent shall effect the allocation among holders of CNC Common Shares of rights to receive cash, NB&T Common Shares, or a combination of cash and NB&T Common Shares in accordance with the Election Forms as follows:

(i) If (A) the number of Cash Election Shares multiplied by the Per Share Cash Consideration, plus (B) the cash to be paid in lieu of fractional NB&T Common Shares pursuant to Subsection (j) below, is less than the Aggregate Cash Consideration, then:

(1) each of the Cash Election Shares (other than Dissenting Shares) shall be converted into the right to receive the Per Share Cash Consideration;

(2) the Exchange Agent will designate first among the No Election Shares and then from the Stock Election Shares (by the method described in Subsection (e) below), a sufficient number of such shares to receive the Per Share Cash Consideration (such redesignated shares hereinafter referred to as “Reallocated Cash Shares”) such that the sum of (a) the product of (1) the sum of

- 12 -

the number of Cash Election Shares plus the number of Reallocated Cash Shares, multiplied by (2) the Per Share Cash Consideration, plus (b) the amount of cash to be paid in lieu of fractional NB&T Common Shares pursuant to Subsection (j) below, equals the Aggregate Cash Consideration, and each of the Reallocated Cash Shares shall be converted into the right to receive the Per Share Cash Consideration; and

(3) each of the No Election Shares and Stock Election Shares that are not Reallocated Cash Shares shall be converted into the right to receive the Per Share Stock Consideration.

(ii) If (A) the number of Cash Election Shares multiplied by the Per Share Cash Consideration, plus (B) the cash to be paid in lieu of fractional NB&T Common Shares pursuant to Subsection (j) below, is greater than the Aggregate Cash Consideration, then:

(1) each of the Stock Election Shares and No Election Shares shall be converted into the right to receive the Per Share Stock Consideration;

(2) the Exchange Agent will designate among the Cash Election Shares (other than Dissenting Shares) (by the method described in Subsection (e) below), a sufficient number of such shares to receive the Per Share Stock Consideration (such redesignated shares hereinafter referred to as “Reallocated Stock Shares”) such that the sum of (a) the product of (1) the number of remaining Cash Election Shares and Mandatory Cash Shares) multiplied by (2) the Per Share Cash Consideration, plus (b) the amount of cash to be paid in lieu of fractional NB&T Common Shares pursuant to Subsection (j) below, equals the Aggregate Cash Consideration, and each of the Reallocated Stock Shares shall be converted into the right to receive the Per Share Stock Consideration; and

(3) each of the Cash Election Shares (other than Dissenting Shares) that are not Reallocated Stock Shares shall be converted into the right to receive the Per Share Cash Consideration.

(iii) If (A) the number of Cash Election Shares (including Dissenting Shares) multiplied by the Per Share Cash Consideration, plus (B) the cash to be paid in lieu of fractional NB&T Common Shares pursuant to Subsection (j) below, is equal to the Aggregate Cash Consideration, then subparagraphs (i) and (ii) above shall not apply, all No Election Shares and all Stock Election Shares shall be converted into the right or receive the Per Share Stock Consideration and all Cash Election Shares shall be converted into the right to receive the Per Share Cash Consideration.

(e) Method of Designation.

(i) If the Exchange Agent is required pursuant to Subsection (d) to designate from among all No Election Shares the Reallocated Cash Shares to receive the Per Share Cash Consideration, each holder of No Election Shares shall have a pro rata

- 13 -

portion (based on such holder’s No Election Shares relative to all No Election Shares) of such holder’s No Election Shares designated as Reallocated Cash Shares.

(ii) If the Exchange Agent is required pursuant to Subsection (d) to designate from among all Stock Election Shares the Reallocated Cash Shares to receive the Per Share Cash Consideration, each holder of Stock Election Shares shall have a pro rata portion (based on such holder’s Stock Election Shares relative to all Stock Election Shares) of such holder’s Stock Election Shares designated as Reallocated Cash Shares.

(iii) If the Exchange Agent is required pursuant to Subsection (d) to designate from among all Cash Election Shares the Reallocated Stock Shares to receive the Per Share Stock Consideration, each holder of Cash Election Shares (except Mandatory Cash Shares and Dissenting Shares) shall have a pro rata portion (based on such holder’s Cash Election Shares relative to all Cash Election Shares) of such holder’s Cash Election Shares designated as Reallocated Stock Shares. If such designation of Cash Election Shares results in all Cash Election Shares other than Dissenting Shares and Mandatory Cash Shares being designated Reallocated Stock Shares and additional Cash Election Shares must be designated Reallocated Stock Shares, then each holder of Mandatory Cash Shares shall have a pro rata portion (based on such holder’s Mandatory Cash Shares relative to all Mandatory Cash Shares) of such holder’s Mandatory Cash Shares designated as Reallocated Stock Shares.

(f) Exchange Fund. At or prior to the Effective Time, NB&T shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Old Certificates, for exchange in accordance with this Article III, an estimated amount of cash (such cash, together with any dividends or distributions with a record date occurring on or after the Effective Time with respect thereto [without any interest on any such cash, dividends or distributions], being hereinafter referred to as the “Exchange Fund”) to be paid pursuant to this Article III in exchange for outstanding CNC Common Shares. Promptly after the Election Deadline, the Exchange Agent shall distribute NB&T Common Shares and make payment of such cash as provided herein. The Exchange Agent shall not be entitled to vote or to exercise any rights of ownership with respect to the NB&T Common Shares held by it from time to time hereunder, except that it shall receive and hold in trust for the recipients of the NB&T Common Shares until distributed thereto pursuant to the provision of this Agreement all dividends or other distributions paid or distributed with respect to such NB&T Common Shares for the account of the persons entitled thereto.

(g) Surrender of Certificates. After the completion of the foregoing allocation, each holder of an Old Certificate who surrenders such Old Certificate to the Exchange Agent shall, upon acceptance thereof by the Exchange Agent, shall be entitled to receive in exchange therefor a certificate representing the full number of NB&T Common Shares and/or the amount of cash into which the aggregate number of CNC Common Shares represented by such surrendered Old Certificate shall have been converted pursuant to Section 3.01(a) and the Old Certificate shall thereafter be cancelled. The Exchange Agent shall accept such Old Certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. Each Old Certificate that is not surrendered to the Exchange Agent in accordance with the

- 14 -

procedures provided for herein shall, except as otherwise herein provided, until duly surrendered to the Exchange Agent, be deemed to evidence ownership of the number of NB&T Common Shares or the right to receive the amount of cash into which such CNC Common Shares shall have been converted. After the Effective Time, there shall be no further transfer on the records of CNC of Old Certificates and, if such Old Certificates are presented to CNC for transfer, they shall be canceled against delivery of certificates for NB&T Common Shares and/or cash as provided above. No interest will be paid on any cash to be paid in exchange for CNC Common Shares that any such holder shall be entitled to receive pursuant to this Article III.

(h) Lost Certificates. If there shall be delivered to the Exchange Agent by any person who is unable to produce any Old Certificate for surrender to the Exchange Agent in accordance with this Article III:

(i) Evidence to the reasonable satisfaction of the Surviving Corporation that such Old Certificate has been lost, wrongfully taken, or destroyed;

(ii) A bond in such amount as the Surviving Corporation or the Exchange Agent may reasonably request as indemnity against any claim that may be made against the Surviving Corporation and/or the Exchange Agent with respect to such Old Certificate; and

(iii) Evidence to the reasonable satisfaction of the Surviving Corporation that such person was the owner of the CNC Common Shares represented by each such Old Certificate claimed by him or her to be lost, wrongfully taken or destroyed and that he or she is the person who would be entitled to present such Old Certificate for exchange pursuant to this Agreement;

then the Exchange Agent, in the absence of actual notice to it that any CNC Common Shares represented by any Old Certificate has been acquired by a bona fide purchaser, shall deliver to such person the cash that such person would have been entitled to receive upon surrender of each such lost, wrongfully taken or destroyed Old Certificate.

(i) Release of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the shareholders of CNC for six months after the Effective Time shall be paid to NB&T. Any shareholders of CNC who have not theretofore complied with this Article III shall thereafter look only to NB&T for payment of the Merger consideration. Notwithstanding the foregoing, neither the Exchange Agent nor NB&T shall be liable to any former holder of CNC Common Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(j) No Fractional NB&T Common Shares.

(i) No certificates or scrip representing fractional NB&T Common Shares shall be issued upon the surrender for exchange of Old Certificates, and such fractional NB&T Common Share interests will not entitle the owner thereof to vote or to any rights of a shareholder of the Surviving Corporation.

- 15 -

(ii) Each holder of CNC Common Shares who would otherwise be entitled to receive a fractional NB&T Common Share shall receive from the Exchange Agent an amount of cash equal to the product obtained by multiplying (a) the fractional NB&T Common Share interest to which such holder (after taking into account all CNC Common Shares held at the Effective time by such holder) would otherwise be entitled by (b) the Per Share Cash Consideration.

(k) No Liability. None of NB&T, CNC, the Exchange Agent or the Surviving Corporation shall be liable to any former holder of CNC Common Shares for any payment of the Per Share Stock Consideration, the Per Share Cash Consideration, any cash in lieu of a fractional NB&T Common Share interest, the Per Share Insurance Payment or any dividends or distributions with respect to NB&T Common Shares delivered to a public official if required by any applicable abandoned property, escheat or similar law.

(l) Withholding Rights. NB&T or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Old Certificates such amounts as NB&T or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any other provision of domestic or foreign tax law (whether national, federal, state, provincial, local or otherwise). To the extent that amounts are so withheld and paid over to the appropriate taxing authority by NB&T or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Old Certificates.

(m) Waiver. The Surviving Corporation may from time to time, in the case of one or more persons, waive one or more of the rights provided to it in this Article III to withhold certain payments, deliveries and distributions; and no such waiver shall constitute a waiver of its rights thereafter to withhold any such payment, delivery or distribution in the case of any person.

(n) Anti-Dilution Provisions. The Per Share Stock Consideration shall be adjusted fully to reflect any occurrence, subsequent to the date of this Agreement but prior to the Effective Time, pursuant to which the outstanding NB&T Common Shares shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities through reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other like changes in NB&T’s capitalization. Such an adjustment shall not be required due to NB&T’s repurchase of shares in connection with NB&T’s employee stock ownership plan. Nothing contained herein shall be deemed to permit any action which may be proscribed by this Agreement.

(o) Dividends and Distributions. No dividends or other distributions with respect to NB&T Common Shares with a record date occurring after the Effective Time shall be paid to the holder of any unsurrendered Old Certificate representing CNC Common Shares converted in the Parent Merger into the right to receive shares of such NB&T Common Shares until the holder thereof shall be entitled to receive NB&T Common Share certificates in Exchange therefor in accordance with the procedures set forth in this Section 3.03. After becoming so entitled in accordance with this Section 3.03(o), the record holder thereof also shall be entitled to receive any such dividends or other distributions, without any interest thereon,

- 16 -

which had become payable after the Effective Time with respect to NB&T Common Shares such holder had the right to receive upon surrender of the Old Certificates.

3.04 Dissenting Shares. Anything contained in this Agreement or elsewhere to the contrary notwithstanding, any holder of an outstanding CNC Common Share that seeks relief as a dissenting shareholder under Section 1701.85 of the OGCL shall thereafter have only such rights (and shall have such obligations) as are provided therein, and the Surviving Corporation shall be required to deliver only such cash payments to which the Dissenting Shares are entitled pursuant to Section 1701.85 of the OGCL. If any holder of Dissenting Shares shall forfeit such right to payment of the fair value under Section 1701.85 of the OGCL, each holder’s Dissenting Shares shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the Per Share Cash Consideration, without interest.

3.05 Tax Consequences. For federal income tax purposes, the Parent Merger is intended to constitute a reorganization within the meaning of Section 368(a) of the Code. The parties hereto adopt this Agreement as a “plan of reorganization” within the meaning of Treasury Department regulation sections 1.368-2(g) and 1.368-3(a).

No event has occurred or circumstance exists that could result in a material increase in premium cost of a Compensation and Benefit Plan that is insured, or a material increase in benefit cost of such Compensation and Benefit Plans that are self-insured.

(iii) None of the Compensation and Benefit Plans is subject to Title IV of ERISA. No liability under Title IV of ERISA has been or is expected to be incurred by CNC or any of its Subsidiaries with respect to any terminated “single-employer plan”, within the meaning of Section 4001(a)(15) of ERISA, formerly maintained by any of them, or any single-employer plan of any entity (an “ERISA Affiliate”) which is considered one employer with CNC under Section 4001(a)(14) of ERISA or Section 414(b) or (c) of the Code (an “ERISA Affiliate Plan”).

(v) Neither CNC nor CNC Bank has any obligations to provide retiree health and life insurance or other retiree death benefits under any Compensation and Benefit Plan, other than benefits mandated by Section 4980B of the Code, and each such Compensation and Benefit Plan may be amended or terminated without incurring liability thereunder. There has been no communication to Employees by CNC or CNC Bank that would reasonably be expected to promise or guarantee such Employees retiree health or life insurance or other retiree death benefits on a permanent basis.

(vi) CNC and CNC Bank do not maintain any Compensation and Benefit Plans covering leased or foreign (i.e., non-United States) Employees, independent contractors or non-employees.

(viii) The consummation of the transactions contemplated by this Agreement would not, directly or indirectly (including, without limitation, as a result of any termination of employment prior to or following the Effective Time) reasonably be expected to (A) entitle any Employee, Consultant or Director to any payment (including severance pay or similar compensation) or any increase in compensation, (B) result in the vesting or acceleration of any benefits under any Compensation and Benefit Plan or (C) result in any material increase in benefits payable under any Compensation and Benefit Plan.

(ix) Neither CNC nor CNC Bank maintains any compensation plans, programs or arrangements the payments under which would not reasonably be expected to be deductible as a result of the limitations under Section 162(m) of the Code and the Treasury Department regulations issued thereunder.

(x) As a result, directly or indirectly, of the transactions contemplated by this Agreement (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), none of NB&T, CNC or the Surviving Corporation, or any of their respective Subsidiaries will be obligated to make a payment that would be characterized as an “excess parachute payment” to an individual who is a “disqualified individual” (as such terms are defined in Section 280G of the Code and applicable regulations thereunder) of CNC on a consolidated basis or which would violate 12 U.S.C. Section 1828(k) or regulations thereunder.

To CNC’s Knowledge, neither CNC nor CNC Bank has received any notice from any person or entity that CNC or CNC Bank or the operation or condition of any property ever owned, leased, operated, or held as collateral or in a fiduciary capacity by any of them are or were in violation of or otherwise are alleged to have liability under any Environmental Law, including, but not limited to, responsibility (or potential responsibility) for the cleanup or other remediation of any Hazardous Materials at, on, beneath, or originating from any such property.

- 33 -

All leases pursuant to which CNC or CNC Bank, as lessee, leases personal property (except for leases that have expired by their terms or that CNC or CNC Bank has agreed to terminate since the date hereof) are valid without default thereunder by the lessee or, to CNC’s Knowledge, the lessor.

(v) Loans; Certain Transactions. Each loan reflected as an asset in the CNC Financial Statements as of December 31, 2008, and each balance sheet date subsequent thereto (i) is evidenced by notes, agreements or other evidences of indebtedness which are true, genuine and what they purport to be, (ii) to the extent secured, has been secured by valid liens and security interests which have been perfected, and (iii) is the legal, valid and binding obligation of the obligor named therein, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

CNC Bank is not a party to a loan, including any loan guaranty, with any director, executive officer or 5% shareholder of CNC or any of its Subsidiaries or any person, corporation or enterprise controlling, controlled by or under common control with any of the foregoing. All loans and extensions of credit that have been made by CNC Bank and that are subject to 12 C.F.R. Part 31, comply therewith.

(w) Allowance for Loan Losses.

The allowance for loan losses reflected on CNC’s Financial Statements was, as of each respective date, determined in accordance with generally accepted accounting principles consistently applied and in accordance with all rules and regulations applicable to CNC and CNC Bank and was, as of the respective date thereof, adequate in all material respects under the requirements of generally accepted accounting principles and applicable regulatory requirements and guidelines to provide for reasonably anticipated losses on outstanding loans, net of recoveries.

(z) Bank Secrecy Act, Anti-Money Laundering and OFAC and Customer Information. CNC is not aware of, has not been advised in writing of, and has no reason to believe that any facts or circumstances exist, which would cause CNC or CNC Bank to be deemed (i) to be operating in violation of the Bank Secrecy Act, the Patriot Act, any order issued with respect to anti-money laundering by the U.S. Department of the Treasury’s Office of Foreign Assets Control, or any other applicable anti-money laundering Law; or (ii) not to be in satisfactory compliance in any material respect with the applicable privacy and customer information requirements contained in any federal and state privacy Laws, including without limitation, in Title V of the ▇▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Act of 1999. CNC is not aware of any facts or circumstances that would cause CNC to believe that any non-public customer information has been disclosed to or accessed by an unauthorized third party in a manner that would cause CNC or any of its Subsidiaries to undertake any material remedial action. The CNC Board (or, where appropriate, the board of directors of CNC Bank) has adopted and implemented an anti-money laundering program that contains adequate and appropriate customer identification verification procedures that comply with Section 326 of the Patriot Act and such anti-money laundering program meets the requirements in all material respects of Section 352 of the Patriot Act and the regulations thereunder, and CNC (or CNC Bank) has complied in all material respects with any requirements to file reports and other necessary documents as required by the Patriot Act and the regulations thereunder.

(aa) CRA Compliance. Neither CNC nor CNC Bank has received any notice of non-compliance with the applicable provisions of the Community Reinvestment Act and the regulations promulgated thereunder, and CNC Bank has received a CRA rating of satisfactory or better from the FDIC as a result of its most recent CRA examination. Neither CNC nor CNC Bank knows of any fact or circumstance or set of facts or circumstances which would be reasonably likely to cause CNC or CNC Bank to receive notice of non-compliance with such provisions or cause the CRA rating of CNC Bank to fall below satisfactory.

(bb) Related Party Transactions. Neither CNC nor CNC Bank has entered into any transactions with any Affiliate or Associate of CNC or CNC Bank (or any Affiliate or Associate of any director, officer or employee of CNC or CNC Bank).

(iv) Immediately prior to the Effective Date, CNC Bank shall pay all employees for any accrued unused vacation time.

(b) Regulatory Approvals and Governmental Authority Actions. All regulatory approvals required to consummate the transactions contemplated hereby shall have been obtained and shall remain in full force and effect and all statutory waiting periods in respect thereof shall have expired and no such approvals shall contain (i) any conditions, restrictions or requirements which the NB&T Board reasonably determines would either before or after the Effective Time have a Material Adverse Effect on NB&T and its Subsidiaries taken as a whole after giving effect to the consummation of the Merger, or (ii) any conditions, restrictions or requirements that are not customary and usual for approvals of such type and which the NB&T Board reasonably determines would either before or after the Effective Time be unduly burdensome.

If CNC or CNC Bank shall have received notice or communication from any Governmental Authority that such Governmental Authority has commenced or intends to commence an investigation of or proceedings against CNC or CNC Bank with respect to a possible violation of any statutes, regulations, or ordinances that such Governmental Authority enforces, such investigation or proceeding shall have been settled between such Governmental Authority and CNC and/or CNC Bank, or such Governmental Authority shall have provided to CNC or CNC Bank written notice that such investigation or proceeding has been concluded and that no further enforcement action is planned by such Governmental Authority.
