(B) No-Election Shares shall be deemed to be Common Stock Election Shares to the extent necessary to have the number of shares represented by the aggregate Common Stock Election Shares equal the Aggregate Common Stock Consideration.

All remaining No-Election Shares shall thereafter be treated as Cash Election Shares;

(C) If all of the No-Election Shares are treated as Common Stock Election Shares under the preceding subsection and the number of shares represented by the aggregate Common Stock Election Shares remains less than the Aggregate Common Stock Consideration, then the Exchange Agent shall convert, on a pro rata basis described in subsection 2.02(e)(iv) below, a sufficient number of Cash Election Shares into Common Stock Election Shares

("Reallocated Common Stock Shares") such that the number of shares represented by the aggregate Common Stock Election Shares, including the Reallocated Common Stock Shares, equals the Aggregate Common Stock Consideration, and thereafter all Reallocated Common Stock Shares will be converted into the right to receive the Common Stock Consideration; and

(D) the Cash Election Shares which are not Reallocated Common Stock Shares shall be converted into the right to receive the Cash Consideration.

(ii) Aggregate Common Stock Consideration Oversubscribed. If the number of shares represented by the aggregate Common Stock Election Shares is more than the Aggregate Common Stock Consideration, then:

(A) all Cash Election Shares and No-Election Shares shall be converted into the right to receive the Cash Consideration;

(B) the Exchange Agent shall convert, on a pro rata basis described in subsection 2.02(e)(iv) below, a sufficient number of Common Stock Election Shares into Cash Election Shares ("Reallocated Cash Shares") such that the amount of cash represented by the remaining aggregate Common Stock Election Shares equals the Aggregate Common Stock Consideration, and thereafter all Reallocated Cash Shares will be converted into the right to receive the Cash Consideration; and

2.06 Exchange Ratio and Cash Consideration Adjustments.

(c) Notwithstanding the forgoing and the provisions of Section 2.02, if a Key Manager Event occurs at any time prior to Closing, each share of CBT Common Stock entitled to receive Cash Consideration shall receive $36.00 per share, and each share of CBT Common Stock to be converted into Common Stock Consideration shall be entitled to receive the lesser of (A) that number of shares of NPB Common Stock determined by dividing $36.00 by the NPB Market Value or (B) that number of shares of NPB Common Stock determined by the Exchange Ratio, as adjusted by Section 2.06(a) above.

(d) As soon as practicable after the Effective Date, but in no event later than ten (10) business days after the Effective Date, NPB shall deliver to the holders of Adjusted CBT Options appropriate notices setting forth the effect of the adjustments described in Section 2.08(a) and Section 2.08(b), above. NPB shall comply with the terms of the CBT Option Plan.

(e) NPB shall take all corporate action necessary to reserve for issuance a sufficient number of shares of NPB Common Stock for delivery upon exercise of Adjusted CBT Options in accordance with this Agreement. Within ten (10) business days after the Effective Date, NPB shall file a registration statement on Form S-8 (or any successor other appropriate forms), with respect to the shares of NPB Common Stock issuable upon exercise of the Adjusted CBT Options and shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained thereon) for so long as such options remain outstanding.

(f) With respect to those individuals who, subsequent to the Merger, will be subject to the reporting requirements under Section 16(a) of the Exchange Act, where applicable, NPB shall administer the CBT Option Plan in a manner consistent with the exemptions provided by Rule 16b-3 promulgated under the Exchange Act.

2.09 Surrender and Exchange of CBT Stock Certificates.

(a) On or prior to the Effective Date, NPB shall deposit with the Exchange Agent, in trust for the benefit of holders of shares of CBT Common Stock electing to receive Cash Consideration pursuant to Section 2.02(b) or Section 2.02(c), sufficient cash to make all payments to such stockholders of CBT pursuant to, and in accordance with, this Article II. On or prior to the Effective Date, NPB shall provide the Exchange Agent with a letter of instruction, in such form as the Exchange Agent may reasonably require, directing the Exchange Agent to pay the Common Stock Consideration in the form of book-entry shares to holders of shares of CBT Common Stock electing to receive Common Stock Consideration pursuant to Section 2.02(b) or Section 2.02(c) and in accordance with, this Article II. As soon as reasonably practicable after the Effective Date, but in any event not later than ten (10) business days after delivery by CBT to NPB of the correct mailing address for each CBT stockholder, NPB shall cause the Exchange

Agent to mail to each holder of one or more certificates representing CBT Common Stock (each, a "CBT Certificate"):

(i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to CBT Certificates shall pass, only upon delivery of CBT Certificates to the Exchange Agent, and which letter shall be in customary form and have such other provisions as NPB reasonably may specify; and

(ii) instructions for effecting the surrender of such CBT Certificates in exchange for the Merger Consideration payable for the shares represented thereby.

After completion of the allocation referred to in Section 2.02(e), and upon surrender of a CBT Certificate to the Exchange Agent together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as reasonably may be required by the Exchange Agent, the holder of such CBT Certificate shall be entitled to receive in exchange therefor:

(A) a statement evidencing book-entry shares representing, in the aggregate the number of shares (including any fraction thereof) that such holder has the right to receive pursuant to Section 2.02 (after taking into account all shares of CBT Common Stock then held by such holder); and/or

(B) a check in the amount of the cash that such holder has the right to receive pursuant to the provisions of Section 2.02 and, with respect to dividends and other distributions, pursuant to the provisions of Section 2.09(b).

(b) Any statement evidencing book-entry shares issued in exchange for CBT Certificates pursuant to Section 2.09(a) above shall be dated the Effective Date and any holder shall be entitled to dividends and all other rights and privileges pertaining to such shares of stock from the Effective Date. Until surrendered, each CBT Certificate (other than CBT Certificates representing Dissenting Shares) shall, from and after the Effective Date, evidence solely the right to receive the Merger Consideration.

(c) If a CBT Certificate is exchanged on a date following one or more record dates after the Effective Date for the payment of dividends or any other distribution on shares of NPB Common Stock, NPB shall pay to such stockholder cash in an amount equal to dividends payable on such shares of NPB Common Stock received in exchange for CBT Certificates and pay or deliver any other distribution to which such stockholder is entitled. No interest shall accrue or be payable in respect of dividends or any other distribution otherwise payable under this Section 2.09(c) upon surrender of CBT Certificates. Notwithstanding the foregoing, no party hereto shall be liable to any holder of CBT Common Stock for any amount paid in good faith to a public official or agency pursuant to any applicable abandoned property, escheat or similar law. Until such time as CBT Certificates are surrendered to NPB for exchange, NPB shall have the right to withhold dividends or any other distributions on the shares of NPB Common Stock issuable to such stockholder.

(d) Each CBT Certificate delivered for exchange under this Section 2.09 must be endorsed in blank by the registered holder thereof or accompanied by a power of attorney to transfer such shares endorsed in blank by such holder.

(e) Upon the Effective Date, the stock transfer books for CBT Common Stock will be closed and no further transfers of CBT Common Stock will thereafter be made or recognized. All CBT Certificates surrendered pursuant to this Section 2.09 will be cancelled.

(f) If there is a transfer of ownership of CBT Common Stock which is not registered in the transfer records of CBT, a statement of book-entry shares evidencing, in the aggregate, the proper number of shares of NPB Common Stock and any dividends or other distributions to which such holder is entitled pursuant to Section 2.09(c), as applicable and appropriate, may be issued with respect to such CBT Common Stock to such a transferee if a CBT Certificate representing such shares of CBT Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

(g) If any CBT Certificate shall have been lost, stolen or destroyed, the Exchange Agent shall deliver in exchange for such lost, stolen or destroyed CBT Certificate, upon the making of a sworn affidavit of that fact by the holder thereof in form satisfactory to the Exchange Agent, the Merger Consideration as may be required pursuant to this Agreement; provided, however, that the Exchange Agent may, in its sole discretion and as a condition precedent to the delivery of the Merger Consideration to which the holder of such CBT Certificate is entitled as a result of the Merger, require the owner of such lost, stolen or destroyed CBT Certificate to deliver a bond in such amount as it may direct as indemnity against any claim that may be made against CBT, NPB or the Exchange Agent or any other party with respect to CBT Certificate alleged to have been lost, stolen or destroyed.

2.10 Anti-Dilution Provisions. If NPB shall, at any time before the Effective Date:

(a) declare a dividend in shares of NPB Common Stock with a record date prior to the Effective Date;

(b) resolve to combine the outstanding shares of NPB Common Stock into a smaller number of shares;

(c) resolve to effect a split or subdivide the outstanding shares of NPB Common Stock with a record date prior to the Effective Date; or

(d) reclassify the shares of NPB Common Stock;

then, in any such event, the number of shares of NPB Common Stock to be delivered to CBT stockholders who are entitled to receive shares of NPB Common Stock in exchange for shares of CBT Common Stock shall be adjusted so that each CBT stockholder shall be entitled to receive such number of shares of NPB Common Stock as such stockholder would have been entitled to receive if the Effective Date had occurred prior to the happening of such event. (By way of

illustration, if NPB shall declare a stock dividend of 3% payable with respect to a record date on or prior to the Effective Date, the Exchange Ratio shall be adjusted upward by 3%.). In addition, in the event that, prior to the Effective Date, NPB enters into an agreement pursuant to which shares of NPB Common Stock would be converted into shares or other securities or obligations of another corporation, proper provision shall be made in such agreement so that each CBT stockholder entitled to receive shares of NPB Common Stock in the Merger shall be entitled to receive such number of shares or other securities or amount or obligations of such other corporation as such stockholder would be entitled to receive if the Effective Date had occurred immediately prior to the happening of such event. Furthermore, in any such event, the dollar amounts referenced in Sections 7.01(c) and 2.06 shall be proportionally adjusted.

5.04 Taking of Necessary Actions. Through the Closing Date, in addition to the specific agreements contained herein, each party hereto shall use reasonable best efforts to take, or cause to be taken by each of its Subsidiaries, all actions, and to do, or cause to be done by each of its Subsidiaries, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the Contemplated Transactions including, if necessary, appealing any adverse ruling in respect of any Application.

CBT shall (unless it believes, after consultation with its counsel, that such notification would violate CBT Board of Directors’ fiduciary duties) notify NPB as promptly as practicable, in reasonable detail, as to any inquiries and proposals which it or any of its representatives or agents may receive; provided, however, that notwithstanding anything to the contrary contained in this Agreement:

(i) CBT may furnish or cause to be furnished confidential and non-public information concerning CBT and its businesses, properties or assets to a third party

(ii) CBT may engage in discussions or negotiations with a third party;

(iii) following receipt of an Acquisition Proposal, CBT may take and disclose to its stockholders a position with respect to such Acquisition Proposal; and/or

As used herein, the term "Acquisition Proposal" means a bona fide proposal (including a written communication that is or becomes the subject of public disclosure) for: (A) any merger, consolidation or acquisition of all or substantially all the assets or liabilities of CBT, any CBT Subsidiary, or any other business combination involving CBT or any CBT Subsidiary; or (B) a transaction involving the transfer of beneficial ownership of securities representing, or the right to acquire beneficial ownership or to vote securities representing, 10% or more of the then outstanding shares of CBT Common Stock or the then outstanding shares of common stock of any CBT Subsidiary.

NPB and each NPB Subsidiary, and CBT and each CBT Subsidiary, shall maintain insurance in such amounts as NPB and CBT, respectively, believe are reasonable to cover such risks as are customary in relation to the character and location of its and their respective Subsidiaries' properties and the nature of its and their respective Subsidiaries' businesses.

(vi) Integration Team. NPB and CBT shall cooperate with each other in the selection of an integration team, which team shall determine if consolidation of some or all of CBT’s bank and/or trust back room operations is feasible and if so, to plan and implement an orderly, cost-effective consolidation of those operations into NPB's operations. Consistent with CBT maintaining its independent status prior to the Effective Date, NPB will provide sufficient resources and personnel to effectively guide the integration team.

(vii) Outside Service Bureau Contracts. NPB and CBT shall cooperate with each other, and if mutually agreed in the interest of an orderly, cost-effective consolidation of operations, terminate any contract or arrangement CBT or any CBT Subsidiary may have with an outside service bureau (including, but not limited to, any entity that provides data processing services for CBT), provided that (i) no notice regarding any such termination shall be required to be delivered to any outside service bureau until after the Effective Date; (ii) no such termination shall be effective until after the Effective Date; and (iii) any fees or penalties associated with any such termination shall not constitute a Material Adverse Effect with respect to CBT.

No such additional accruals or reserves made by CBT pursuant to this subsection shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence of CBT or its management with any such adjustments.

NPB and CBT shall each deliver to the other, as soon as practicable after the end of each month and after the end of each calendar quarter prior to the Effective Date, commencing with the month ended May 31, 2007, an unaudited consolidated balance sheet as of such date and related unaudited consolidated statements of income and cash flows for the periods then ended, which financial statements shall fairly present, in all material respects, its consolidated financial condition, results of operations and cash flows for the periods then ended in accordance with GAAP, subject to year-end audit adjustments and footnotes.

(xi) Delivery of SEC Documents. NPB and CBT shall each deliver to the other copies of all reports filed with the SEC or FDIC under the Exchange Act and the Federal Deposit Insurance Act promptly upon the filing thereof.

(i) Employees, Severance Policy.

(A) Subject to NPB's usual personnel and qualification policies, NPB will endeavor to continue the employment of all current non-management employees of CBT in positions that will contribute to the successful performance of the combined organization. More specifically, NPB will, after consultation with ▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇▇▇▇, President and Chief Executive Officer of CBT, prior to or soon after the Closing Date, inform each CBT employee of the likelihood of such employee having continued employment with the Surviving Bank following the Closing, it being NPB’s intent to retain most of CBT’s customer contact personnel, and NPB will permit any CBT employee to apply for any employment position posted as available with the

Surviving Bank, NPB, NPBank or any other NPB Subsidiary. NPB will give any CBT applicant priority consideration. Where there is a coincidence of responsibilities, NPB will try to reassign the affected individual to a needed position that utilizes the skills and abilities of the individual. If that is impracticable or if NPB elects to eliminate a position or does not offer the employee comparable employment (i.e., a position of substantially similar job description or responsibilities at substantially the same salary level in a work location within thirty (30) miles of the employee’s then current work location with CBT), NPB will make severance payments to the displaced employee as set forth in this Section 5.08(c)(i).

(B) Subject to the following minimum and maximum benefits, NPB will grant an eligible employee two weeks of severance pay (at his or her then current pay rate) for each year of an employee's service with CBT or any CBT Subsidiary prior to the employment termination date. The minimum benefit shall be eight weeks' salary for full-time employees, which will be pro-rated for part-time employees. The maximum severance benefit will be 26 weeks' salary.

(C) All employees of CBT or of any CBT Subsidiary on the date hereof will be eligible for severance benefits set forth in this Section 5.08(c)(i), except that:

(1) No employee of CBT or of any CBT Subsidiary who shall receive any payment or benefit pursuant to any "change in control" agreement or similar plan or right shall be eligible for any severance benefits; and

(2) No employee of CBT or of any CBT Subsidiary with an operating systems conversion support role of any kind shall be eligible for any severance benefits unless such employee continues in employment for 30 days following the actual consolidation and conversion of CBT’s operating systems with and into NPB's operating systems, which, as of the date hereof, is scheduled to be completed not later than sixty days after the Effective Date. In addition to these severance benefits, CBT is also authorized to pay retention bonuses to persons identified on Exhibit 5.08(c) in amounts mutually agreed between CBT and NPB prior to Closing provided that those persons remain employed by CBT for 30 days following the conversion of CBT’s computer systems with and into NPB’s operating systems.

(D) Each person eligible for severance benefits will remain eligible for such benefits if his or her employment is terminated, other than for "cause", within twelve months after the Effective Date. Any person whose employment with NPB or any NPB Subsidiary is terminated without "cause" after twelve months from the Effective Date shall receive such severance benefit from NPB or such NPB Subsidiary as is provided for in NPB's general severance policy for such terminations (with full credit being given for each year of service with CBT or any CBT Subsidiary in addition to the years of service with NPB or any NPB Subsidiary).

(E) For purposes of this Section 5.08(c)(i), "cause" means the employer's good faith reasonable belief that the employee (1) committed fraud, theft or embezzlement; (2) falsified corporate records; (3) disseminated confidential information concerning customers, NPB, any NPB Subsidiary or any of its or their employees in violation of any applicable confidentiality agreement or policy; (4) had documented unsatisfactory job performance under NPB's dismissal

policy; or (5) violated NPB's Code of Conduct. The foregoing definition of "cause" is the definition of "cause" used by NPB and its Subsidiaries in the ordinary course of its business.

(ii) Employee Benefits.

(A) As of the Effective Date, each employee of CBT or of any CBT Subsidiary who becomes an employee of NPB or of any NPB Subsidiary shall be entitled to full credit for each year of service with CBT of a CBT Subsidiary for purposes of determining eligibility for participation, including, but not limited to, applicability of minimum waiting periods, and vesting, but not benefit accrual for periods of prior service, in NPB's, or as appropriate, in the NPB Subsidiary's, employee benefit plans, programs and policies. NPB shall use the original date of hire by CBT or a CBT Subsidiary in making these determinations.

(B) The employee benefits provided to former employees of CBT or a CBT Subsidiary after the Effective Date shall be reasonably equivalent in the aggregate to the employee benefits provided by NPB or its Subsidiaries to their similarly situated employees. The medical, dental and life insurance plans, programs or policies, if any, that become applicable to former employees of CBT or any CBT Subsidiary shall not contain any exclusion or limitation with respect to any pre-existing condition of any such employees or their dependents and any deductibles or out-of-pocket expenses paid under any CBT Benefit Plans shall be credited towards deductibles and out-of-pocket expenses under applicable plans of NPB upon delivery of appropriate documentation.

(C) Subject to the other provisions of this Section 5.08(c)(ii) and Section 2.08, after the Effective Date, NPB may discontinue, amend, convert to, or merge with, an NPB or NPB Subsidiary plan any CBT Benefit Plan, subject to such plan's provisions and applicable law.

(iii) Election of NPBank Director.

(A) Upon consummation of the Merger and subject to compliance with all applicable legal requirements, NPB shall cause NPBank to elect one person selected by CBT's Board of Directors and approved by NPB (which approval will not be unreasonably withheld) (a "CBT NPBank Nominee") as a director of NPBank, effective the Effective Date, to hold office until his successor is elected and qualified or otherwise in accordance with applicable law, the articles of association and bylaws of NPBank; and NPB and NPBank shall take all steps necessary to insure that CBT NPBank Nominee is re-elected to NPBank's Board of Directors for each of the three years, following the Effective Date if such person is in office as a director of NPBank on the annual election dates.

(B) If the CBT NPBank Nominee, or any successor, resigns, dies or is otherwise removed from NPBank's Board of Directors prior to the end of the third one-year term, the former CBT directors who are then serving as CBT Board Members, by a plurality vote, shall have the right to select the successor to such CBT NPBank Nominee, or any successor, subject to (A) compliance with the NPB/NPBank Bylaws Restrictions, (B) such person being “independent” as defined by the SEC and Nasdaq, and (C) approval of such person by NPB (which approval will not be unreasonably withheld). NPB shall take all reasonable steps to elect such successor to the NPBank Board of Directors.

(iv) CBT Board.

(A) Upon consummation of the Merger, NPB shall operate CBT as a Delaware banking corporation consisting of all CBT’s present community offices. The Board of Directors of CBT shall, during this time period, consist of all the members of CBT’s Board of Directors at the Effective Date who are identified by CBT pursuant to Section 1.02(e) above and two representatives selected by NPB, one of which shall serve as the chairman of the board of CBT. NPB reserves the right to add additional members to the CBT Board of Directors in NPB’s discretion from time to time.

(B) CBT's current non-employee directors who become CBT Board Members following the Effective Date shall receive a retainer and board meeting fees comparable to the retainer and board meeting fees received by them as CBT directors at the date hereof. Other persons who may be selected for service on the CBT Board of Directors shall be compensated as determined by NPB’s Compensation Committee. CBT's current non-employee directors who become CBT Board Members shall have the option of electing to receive such NPB standard compensation. The CBT Board Members shall have indemnification and insurance coverage no less favorable than members of the Board of Directors of NPBank. The consulting agreements with Messrs. ▇▇▇▇▇ and ▇▇▇▇▇▇▇ shall not be further extended and shall terminate upon notice at the end of their current terms. NPB intends to offer to Mr. W. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇ an opportunity to extend the term of his present consulting agreement.

(C) NPB shall operate CBT and maintain the CBT Board Members at the foregoing compensation level, for a period of at least three years after the Effective Date. This covenant shall expire if (i) NPB shall be acquired, merged or otherwise sold, or (ii) if agreed to by a majority vote of both the CBT Board Members and the NPBank Board of Directors

(v) Indemnification, Insurance.

(A) NPB shall indemnify, defend, and hold harmless the directors, officers, employees and agents of CBT and the CBT Subsidiaries (each, an "Indemnified Party") against all losses, expenses (including reasonable attorneys' fees), claims, damages or liabilities and amounts paid in settlement arising out of actions or omissions or alleged acts or omissions (collectively, "Prior Acts") occurring at or prior to the Effective Date (including the Contemplated Transactions) to the fullest extent permitted by Delaware law, including provisions relating to advances of expenses incurred in the defense of any proceeding to the full extent permitted by Delaware law upon receipt of any undertaking required by Delaware law. Without limiting the foregoing, in a case (if any) in which a determination by NPB is required to effectuate any indemnification, NPB shall direct, at the election of the Indemnified Party, that the determination shall be made by independent counsel mutually agreed upon between NPB and the Indemnified Party.

(B) NPB shall use its reasonable best efforts to, and it shall cause CBT to, keep in effect provisions in its articles of incorporation or association and bylaws providing for exculpation of director and officer liability and its indemnification of the Indemnified Parties to the fullest extent permitted by Delaware law, which provisions shall not be amended except as required by applicable law or except to make changes permitted by law that would enlarge the Indemnified Parties' right to indemnification.

(C) NPB shall use its reasonable best efforts (and CBT shall cooperate and assist prior to the Effective Date in these efforts), at no expense to the beneficiaries, to:

(1) maintain directors' and officers' liability insurance, together with an errors and omissions policy for trust activities and a special policy for domicile activities, ("D&O Insurance") for the Indemnified Parties with respect to matters occurring at or prior to the Effective Date, issued by a carrier assigned a claims-paying ability rating by A.M. Best & Co. of "A (Excellent)" or higher; or

(2) obtain coverage for Prior Acts for the Indemnified Parties under the directors' and officers' liability insurance policies currently maintained by NPB;

in either case, providing at least the same coverage as the D&O Insurance currently maintained by CBT and containing terms and conditions which are no less favorable to the beneficiaries, for a period of at least six (6) years, but not less than three (3) years, from the Effective Date; provided, that NPB shall not be obligated to make annual premium payments for such six-year period in respect of the D&O Insurance which exceed, for the portion related to CBT's directors and officers, $313,658 (150% of the annual premium payment, as of January 1, 2007, under CBT's current policy in effect on the date of this Agreement) (the "Maximum Amount"); provided, further, that in no event shall such coverage be maintained for less than three (3) years. If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount in any year, NPB shall use its reasonable best efforts to maintain the most advantageous policies of directors' and officers' liability insurance obtainable for a premium equal to the Maximum Amount.

(D) If any claim is made against present or former directors, officers or employees of CBT or any CBT Subsidiary who are covered or potentially covered by insurance, neither NPBank nor NPB shall do anything that would forfeit, jeopardize, restrict or limit the insurance coverage available for that claim until the final disposition thereof.

(E) If NPB or any of its successors or assigns shall consolidate with or merge into any other person and shall not be the continuing or surviving person of such consolidation or merger or shall transfer all or substantially all of its assets to any person, then and in each case, proper provision shall be made so that the successors and assigns of NPB shall assume the obligations set forth in this Section 5.08(c)(v).

(F) The provisions of this Section 5.08(c)(vi) are intended to be for the benefit of and shall be enforceable by, each Indemnified Party, his or her heirs and representatives.

(G) NPB shall pay all expenses, including reasonable attorneys' fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided for in this Section 5.08(c)(v).

(vi) Conduct of NPB's Business. Through the Closing Date, NPB shall use its reasonable good faith efforts to preserve its business organization intact, maintain good relationships with employees, and preserve the good will of customers of NPB and others with whom business relationships exist. Through the Closing Date, NPB shall not, and NPB shall not permit any NPB Subsidiary to, take any action reasonably likely to (a) result in NPB’s representations and warranties contained in Article IV hereof not being true in any material respect; or (b) result in any of the conditions set forth in Article VI hereof not being satisfied.

(vii) CBT Common Stock. NPB will not directly or indirectly acquire any CBT Common stock following the date hereof other than pursuant to the Closing of the Contemplated Transactions.
