(F) Dissenting ENB Shareholders. If there are holders of ENB Common Stock who dissent from the Merger and exercise and perfect the right to obtain valuation of and payment for their shares ("Dissenting ENB Shares") pursuant to Section 215a(b) of the National Bank Act (12 U.S.C. ss.215a(b)), the following provisions will govern payments to be made in respect of Dissenting ENB Shares: (1) All payments in respect of Dissenting ENB Shares, if any, will be made by NPB or the Surviving Bank, as they shall agree. (2) Dissenting ENB Shares, if any, will be deemed to have been retired and cancelled immediately prior to the Merger, with the effect that no conversion thereof will occur pursuant to subsection (f)(ii)(A) above unless and until such holder shall have failed to perfect or effectively shall have withdrawn or lost his right to appraisal and payment under such section. If any such holder of ENB Common Stock shall have so failed to perfect or effectively shall have withdrawn or lost such right, each of his shares of ENB Common Stock shall thereupon be deemed to have been converted into, on the Effective Date, the right to receive shares of NPB Common Stock and cash in lieu of fractional shares as set forth in Section 1.02(f)(ii)(A) and (C) above. (g) Stock Options.

The adjustment provided herein with respect to any options which are "incentive stock options", as defined in Section 422 of the IRC, shall be and is intended to be effected in a manner which is consistent with Section 424(a) of the IRC. As a result of this Agreement and as provided in the ENB 1996 Stock Incentive Plan, all options issued and outstanding under the ENB 1996 Stock Incentive Plan shall become 100 percent vested and immediately exercisable. (ii) As soon as practicable after the Effective Date, NPB shall deliver to the holders of ENB Options appropriate notices setting forth such holders' rights pursuant to the ENB Stock Option Plans (including that, by virtue of the Merger and pursuant to the terms of the ENB Stock Option Plans, the ENB Stock Options have become fully vested and exercisable) and the agreements evidencing the grants of such ENB Stock Options shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 1.02(g) after giving effect to the Merger and the terms of the ENB Stock Option Plans). NPB shall comply with the terms of the ENB Stock Option Plans and shall take such reasonable steps as are necessary or required by, and subject to the provisions of, such ENB Stock Option Plans, to have the ENB Stock Options, if any, which qualified as "incentive stock options" prior to the Effective Date, continue to qualify as "incentive stock options" after the Effective Date. (iii) 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 ENB Stock Options in accordance with this Agreement. Promptly after the Effective Date, NPB shall file a registration statement on Form S-3 or Form S-8, as the case may be (or any successor other appropriate forms), with respect to the shares of NPB Common Stock subject to such options and shall use commercially reasonable 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. 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 ENB Stock Option Plans in a manner consistent with the exemptions provided by Rule 16b-3 promulgated under the Exchange Act. 9 (h) Surrender and Exchange of ENB Stock Certificates. (i) Each holder of shares of ENB Common Stock who surrenders to NPB the certificate or certificates representing such shares (each, an "ENB Certificate") shall be entitled to receive in exchange therefor, as soon as practicable after the Effective Date, a certificate for the number of whole shares of NPB Common Stock into which such holder's shares of ENB Common Stock have been converted by the Merger, together with a check for cash in lieu of any fractional share in accordance with subsection (f)(ii)(C) above (the "Merger Consideration"). (ii) Each certificate for shares of NPB Common Stock (each, a "NPB Certificate") issued in exchange for ENB Certificates pursuant to subsection (h)(i) above shall be dated the Effective Date and be entitled to dividends and all other rights and privileges pertaining to such shares of stock from the Effective Date. Until surrendered, each ENB Certificate shall, from and after the Effective Date, evidence solely the right to receive NPB Certificates pursuant to subsection (h)(i) above and a check for cash in lieu of any fractional share in accordance with subsection (f)(ii)(C) above. If an ENB Certificate is exchanged on a date following one or more record dates for the payment of dividends or any other distribution on shares of NPB Common Stock, NPB shall pay to such shareholder cash in an amount equal to dividends payable on such shares of NPB Common Stock and pay or deliver any other distribution to which such shareholder is entitled. No interest shall accrue or be payable in respect of dividends or any other distribution otherwise payable under this subsection (h)(ii) upon surrender of ENB Certificates. Notwithstanding the foregoing, no party hereto shall be liable to any holder of ENB 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 ENB 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 shareholder. (iii) Each ENB Certificate delivered for exchange under this subsection (h) 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. (iv) Upon the Effective Date, the stock transfer books for ENB Common Stock will be closed and no further transfers of ENB Common Stock will thereafter be made or recognized. All ENB Certificates surrendered pursuant to this subsection (h) will be cancelled. (v) As soon as reasonably practicable after the Effective Date, NPB shall cause Bank or another institutional entity selected by NPB, as the exchange agent (the "Exchange 10 Agent") to mail to each holder of an ENB Certificate (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the ENB Certificates shall pass, only upon delivery of the ENB 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 ENB Certificates in exchange for the applicable Merger Consideration. Upon surrender of an ENB 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 ENB Certificate shall be entitled to receive in exchange therefor (A) one or more shares of NPB Common Stock representing, in the aggregate, the whole number of shares that such holder has the right to receive pursuant to Section 1.02(f) (after taking into account all shares of ENB Common Stock then held by such holder) and (B) a check in the amount equal to the cash that such holder has the right to receive pursuant to the provisions of this Section 1.02, including cash in lieu of any fractional shares and dividends and other distributions pursuant to Section 1.02(h)(ii). In the event of a transfer of ownership of ENB Common Stock which is not registered in the transfer records of ENB, one or more NPB Certificates evidencing, in the aggregate, the proper number of shares of NPB Common Stock, a check in the proper amount of cash in lieu of any fractional shares and any dividends or other distributions to which such holder is entitled pursuant to Section 1.02(h)(ii), may be issued with respect to such ENB Common Stock to such a transferee if the ENB Certificate representing such shares of ENB 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.

(By way of illustration, if NPB shall declare a stock dividend of 7% payable with respect to a record date on or prior to the Effective Date, the exchange ratio set forth in subsection (f)(ii)(A) hereof shall be adjusted upward by 7%.) 11 ARTICLE II REPRESENTATIONS AND WARRANTIES OF ENB ENB hereby represents and warrants to NPB as follows: 2.01 Organization.

Any partial year of service shall be treated as a full year for purposes of severance benefit calculations. Except as provided below, severance benefits shall not be payable to: (A) any non-exempt ENB employee who receives and turns down two job offers of equal or higher salary grade at a location within a 15 mile radius of the employee's home; and (B) any exempt ENB employee who receives and turns down a job offer of equal or higher salary grade at a location within a 25 mile radius of the employee's home. NPB shall also make severance benefits available to ENB personnel whose employment with NPB is terminated by NPB without "cause" within one year after the Effective Date, in accordance with the Merger Employment Policies. Notwithstanding the foregoing, each full-time ENB non-community office and lending staff employee who has received the offer(s) of employment specified in clause (A) or (B) above and who elects not to accept an offer of employment with NPB (or who elects to terminate employment with NPB within 90 days of the Effective Date) shall be entitled to four weeks of severance benefits. Any person whose employment with NPB is terminated by NPB without "cause" after one year from the Effective Date shall receive such severance benefit from NPB as is provided for in NPB's general severance policy for such terminations (with full credit being given for each year of service with ENB). For purposes of this Section 4.07(c)(iv), "cause" shall mean the employer's good faith reasonable belief that the employee committed fraud, theft, embezzlement, falsified corporate records, disseminated confidential information concerning customers, NPB, Bank or its employees, had documented unsatisfactory job performance under Bank's dismissal policy, or violated Bank's Code of Conduct. The foregoing definition of "cause" is the definition of "cause" used by Bank in the ordinary course of its business. (v) Employee Benefits. As of the Effective Date, ENB employees who become employees of NPB or of any NPB Subsidiary shall be entitled to full credit for each year of service with ENB for purposes of determining eligibility for participation and vesting, but not benefit accrual, in NPB's employee benefit plans, programs and policies. The employee benefits provided to former 42 employees of ENB after the Effective Date shall be substantially similar to the employee benefits, in the aggregate, provided by NPB or its Subsidiaries to their similarly situated employees. The NPB medical, dental and life insurance plans, programs or policies, if any, that become applicable to former ENB employees shall not contain any exclusion or limitation with respect to any pre-existing condition of any such employees or their dependents. Subject to the foregoing, after the Effective Date, NPB may discontinue, amend or convert to an NPB plan any particular benefit or welfare plan of ENB, subject to such plan's provisions and applicable law. (vi) Qualified Plans. As of the Effective Date, the account balances of ENB employees under the ENB 401(k) Profit Sharing Plan and under the ENB Employee Stock Ownership Plan shall become 100 percent vested, provided, however, such vesting shall not take place if such vesting would cause the Merger to fail to qualify for "pooling of interests" accounting treatment. (vii) Management Incentive Plan. If the Merger occurs prior to December 31, 1998, the annual portion of the ENB Management Incentive Plan (the "MIP") shall be continued through December 31, 1998. If the Merger occurs after December 31, 1998, the MIP may be continued or discontinued as determined by the NPB Board of Directors. In any event, the ENB Board of Directors shall determine in good faith, with the consent of NPB (which consent shall not be unreasonably withheld), the appropriate level of payouts to be made under the MIP for 1998. In making its determination, the ENB Board of Directors shall disregard any extraordinary expenses or charges related to the Merger that would otherwise cause a reduction in payouts under the MIP. (viii) Calculations of ESOP, MIP and Profit Sharing. The calculations determining the amounts to be included in the ESOP, MIP and profit sharing plans for 1998 shall be done prior to making any deductions for reserves to be created or expenses incurred in connection with the Merger. (ix) Deferred Compensation Arrangement. On the Effective Date or on January 1, 1999 if the Effective Date shall precede January 1, 1999, the ENB Deferred Compensation Arrangement shall be terminated, and subject to any applicable income tax withholding requirements, all deferred compensation account balances shall be paid out in cash to plan participants. (x) Election of NPB Directors. Upon consummation of the Merger and subject to compliance with all applicable legal requirements, NPB shall elect two persons selected by ENB's Board of Directors and approved by NPB (which approval will not be unreasonably withheld) as directors of NPB, effective the Effective Date, one to serve as a Class I director with a term through April 2000 and the other to serve as a Class II director with a term 43 through April 2001, and each to be re-nominated for at least one full three-year term thereafter (each, an "ENB NPB Nominee"). In the event that any ENB NPB Nominee, or any successor, resigns, dies or is otherwise removed from NPB's Board of Directors prior to the end of such person's full three-year term, the Elverson Continuing Directors, by a plurality vote, shall have the right to select such person's successor, subject to NPB's approval (which approval will not be unreasonably withheld), and NPB shall take all reasonable steps necessary to elect such successor to the NPB Board of Directors. (xi) Elverson Division, Elverson Board. (A) Upon consummation of the Merger and subject to compliance with all applicable legal requirements, NPB shall cause Bank to establish and operate a separate banking division called "Elverson National Bank, a Division of National Penn Bank" (the "Elverson Division"). The Elverson Division will consist of all ENB's present branch offices with the following additions and deletion: (1) Bank's Lionville office would become an Elverson Division office; (2) Bank's Gay Street, West Chester office would be combined into ENB's office at High Street, West Chester; and (3) ENB's Sinking Spring office would become a Bank office. It is NPB's intent to utilize the Elverson Division in the expansion of NPB's branch banking system in Chester County, Pennsylvania, either by the opening of de novo branches or by the acquisition of deposits and assets, such branches to be operated under the "Elverson Division" banner. Subject to NPB's approval of the planned capital expenditures and operating budget for the proposed branches, the Elverson Division may open two branches in Chester County in the three years following the Effective Date; provided, however, that approval of the second branch will be subject to the first branch having achieved $10 million in deposits. NPB anticipates that the Elverson Division will have the same lending authority limits as ENB has at the date hereof, in accordance with NPB's credit quality standards. (B) Upon consummation of the Merger, NPB shall cause Bank to establish the "Elverson Division Board of Directors" (the "Elverson Board"). The Elverson Board shall consist of the members of ENB's Board of Directors at the Effective Date, an NPB executive officer selected by NPB, and such other persons as the Elverson Board shall select from time to time. NPB anticipates that the Elverson Board will emphasize sales, marketing and expansion. ENB's current non-employee directors who become members of the Elverson Board shall receive annual director compensation equal to the annual director compensation received by them at the date hereof. Other persons who may be selected for service on the Elverson Board shall be compensated in accordance with NPB's standard compensation arrangements for divisional board members, which is partially fixed and partially incentive-based compensation. ENB's current non-employee directors who become 44 members of the Elverson Board shall have the option of electing to receive such NPB standard compensation. The Elverson Board shall have indemnification and insurance coverage no less favorable than members of the Board of Directors of Bank. (C) NPB shall operate the Elverson Division, and maintain the Elverson Board at the foregoing compensation level, for a period of at least five years after the Effective Date, except that this covenant shall expire if and when NPB shall be acquired or otherwise sold and thereafter the members of NPB's Board of Directors do not constitute at least 50% of the members of the surviving corporation's board of directors. (xii) Indemnification, Insurance. (A) NPB shall indemnify, defend, and hold harmless the directors, officers, employees and agents of ENB (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 transactions contemplated by this Agreement) to the fullest extent permitted under the Pennsylvania Business Corporation Law ("PBCL"), including provisions relating to advances of expenses incurred in the defense of any proceeding to the full extent permitted by the PBCL upon receipt of any undertaking required by the PBCL. 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 cause Bank to keep in effect provisions in its Articles of Incorporation and Bylaws of Bank providing for exculpation of director and officer liability and its indemnification of the Indemnified Parties to the fullest extent permitted under the PBCL, 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 ENB shall cooperate and assist prior to the Effective Date in these efforts), at no expense to the beneficiaries, (i) to maintain (x) directors' and officers' liability insurance ("D&O Insurance") for the Indemnified Parties with respect to matters occurring at or prior to the Effective Date, and (y) fiduciary liability insurance ("Fiduciary Insurance") for the present and former fiduciaries of ENB's profit-sharing plan and employee stock ownership plan (the "Fiduciary Insurance"), each issued by a carrier or carriers assigned a claims-paying ability rating by A.M. Best & Co. of "A 45 (Excellent)" or higher, or (ii) to obtain coverage for Prior Acts for the Indemnified Parties under the fiduciary and directors' and officers' liability insurance policies currently maintained by NPB, in either case, providing at least the same coverage as the D&O Insurance and Fiduciary Insurance, respectively, currently maintained by ENB and containing terms and conditions which are no less favorable to the beneficiaries, for a period of at least six (6) years from the Effective Date; provided, that NPB shall not be obligated to make premium payments for such six-year period in respect of the D&O Insurance and the Fiduciary Insurance which exceed, for the portion related to ENB's directors and officers, 150 percent of the annual premium payments ($18,083.00 at the date hereof) of ENB's current policy in effect as of the date of this Agreement (the "Maximum Amount"). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, 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) In the event any claim is made against present or former directors, officers or employees of ENB or any of the Fiduciaries who is covered or potentially covered by insurance, neither Bank 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 4.07(c)(xi). (F) The provisions of this Section 4.07(c)(xi) 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 4.07(c)(xi). (xiii) Publication of Post-Merger Results of Operations. NPB shall use its reasonable best efforts to publish (if necessary, on Form 8-K) no more than twenty days after the end of the first month after the Effective Date in which there are at least thirty days of post-Merger combined operations (which month may be the month in which the Effective Date occurs), the financial information contemplated by and in accordance with the terms of SEC Accounting Series Releases No. 130 and 135 and Section 201.01 of 46 the SEC's Codification of Financial Reporting Policies and other applicable accounting rules. (xiv) Repurchases of NPB Common Stock. Through the Closing Date, except as otherwise consented to in writing by ENB (which consent shall not be unreasonably withheld), NPB shall not repurchase, redeem or otherwise acquire any shares of NPB Common Stock. (xv) 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, and in all material respects conduct its businesses and engage in transactions in the ordinary course without radical change. (xvi) Other Transactions. Through the Closing Date, except as otherwise consented to in writing by ENB (which consent shall not be unreasonably withheld), NPB shall not enter into any agreement with a third party concerning any acquisition of such third party by, or merger or consolidation of such third party with, NPB if (A) under applicable regulations, NPB would be required to present pro forma financial information reflecting that transaction in the Registration Statement, or (B) NPB would propose to issue shares of NPB Common Stock in such transaction in an amount exceeding twenty percent of the outstanding shares of NPB Common Stock on the date hereof.

[THE REMAINDER OF THIS PAGE IS INTENTIONALLY LEFT BLANK] 51 ARTICLE VI TERMINATION, WAIVER AND AMENDMENT 6.01 Termination. This Agreement may be terminated on or at any time prior to the Closing Date: (a) By the mutual written consent of the parties hereto; (b) By NPB or ENB: (i) If there shall have been any breach of any representation, warranty or obligation of the other party hereto (subject to the same standards as set forth in Sections 5.01(b) or 5.02(b), as the case may be) and such breach can not be, or shall not have been, remedied within 30 days after receipt by such party of written notice specifying the nature of such breach and requesting that it be remedied; (ii) If the Closing Date shall not have occurred prior to February 28, 1999 (except that if the Closing Date shall not have occurred by such date because of a breach of this Agreement by a party hereto, such breaching party (or Bank in NPB's case) shall not be entitled to terminate this Agreement in accordance with this provision); (iii) If any Regulatory Authority whose approval or consent is required for consummation of the Merger shall issue a definitive written denial of such approval or consent and the time period for appeals and requests for reconsideration has run; or (iv) If any shareholder vote contemplated by this Agreement is not obtained at the ENB Shareholders Meeting or the NPB Shareholders Meeting. (c) By ENB, at any time during the ten-day period following the Determination Date, if both of the following conditions occur on the Determination Date: (1) the NPB Market Value shall be less than $27.00 per share [the dollar amount $27.00 shall be adjusted to $21.60 upon completion of the NPB Stock Split]; and (2)(i) the quotient obtained by dividing the NPB Market Value by $33.75 per share [the dollar amount $33.75 shall be adjusted to $27.00 upon completion of the NPB Stock Split] shall be less than (ii) the quotient obtained by dividing the Average Index Price by the Index Price on the Starting Date and subtracting 0.05 from the quotient in this clause (2)(ii); subject, however, to the following: If ENB shall elect to terminate this Agreement pursuant to this Section 6.01(c), it shall 52 give written notice thereof to NPB (provided that such notice of election to terminate may be withdrawn at any time within the aforementioned ten-day period). During the five-day period commencing with its receipt of such notice, NPB shall have the option to elect to increase the exchange ratio set forth in Section 1.02(f)(ii)(A), as adjusted pursuant to Section 1.02(f)(ii)(E), to 1.25 shares of NPB Common Stock [the number 1.25 shall be adjusted to 1.5625 upon completion of the NPB Stock Split] in exchange for each share of ENB Common Stock and the Closing Date shall be postponed by the minimum amount of time necessary, if any, to accommodate NPB's election of such option (i.e., up to a five-day period). If NPB so elects within such five-day period, it shall give prompt written notice to ENB of such election, whereupon no termination shall have occurred pursuant to this Section 6.01(c) and this Agreement shall remain in effect in accordance with its terms (except as the Exchange Ratio shall have been so modified).

"Average Index Price" means the average of the Index Prices for the twenty trading days ending on the Determination Date. "Starting Date" means July 20, 1998. If any company belonging to the Index Group declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares, or similar transaction between the Starting Date and the Determination Date, the prices for the common stock of such company shall be appropriately adjusted for the purposes of applying this Section 6.01(c). (d) By ENB, at any time during the ten-day period following the Determination Date, if the NPB Market Value shall be less than $25.31 per share [the dollar amount $25.31 shall be adjusted to $20.25 upon completion of the NPB Stock Split]; 53 (e) By ENB pursuant to Section 4.05 hereof; or (f) By ENB if NPB or any of its Subsidiaries shall enter into any agreement with a third party concerning any merger or consolidation of NPB with or into such third party or the acquisition of all or substantially all the assets of NPB, or any person or entity shall have acquired at least 19.9% of the outstanding shares of NPB Common Stock. 6.02 Effect of Termination. If this Agreement is terminated pursuant to Section 6.01 hereof or otherwise, this Agreement shall forthwith become void, other than Sections 4.02(c) and 7.01 hereof which shall remain in full force and effect, and there shall be no further liability on the part of NPB or ENB to the other, except for any liability of NPB or ENB under such sections of this Agreement and except for any liability arising out of a willful breach of this Agreement giving rise to such termination. ARTICLE VII MISCELLANEOUS 7.01 Expenses and Other Fees. (a) Except for the cost of printing and mailing the Prospectus/Proxy Statement which shall be shared equally and except as set forth in Section 7.01(b), each party hereto shall bear and pay all costs and expenses incurred by it in connection with the transactions contemplated hereby, including fees and expenses of its own financial consultants, accountants and counsel. (b) If ENB fails to complete the transactions contemplated herein after the occurrence of one of the following two events and NPB shall not be in material breach of this Agreement, ENB shall immediately pay NPB a fee of five million dollars ($5,000,000.00): (i) ENB exercises its termination rights pursuant to Section 6.01(e) of this Agreement; or (ii) the failure of ENB shareholders to approve the Merger at a meeting called for such purpose if at the time of such meeting there has been an announcement by a person or group of persons (other than NPB) of an offer or proposal to acquire 19.9% or more of the ENB Common Stock then outstanding, or to acquire, merge, or consolidate with ENB, or to purchase all or substantially all of ENB's assets. (c) If NPB fails to complete the transactions contemplated herein after the failure of NPB shareholders to approve the Merger at a meeting called for such purpose and ENB shall not be in 54 material breach of this Agreement, NPB shall immediately pay ENB a fee of one million dollars ($1,000,000.00). 7.02 Non-Survival of Representations and Warranties; Disclosure Schedules.

Any agreement on the part of a party hereto to any extension or waiver shall be valid only if set forth in an instrument in writing signed by a duly authorized officer on behalf of such party, but such waiver or failure to insist on strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. 7.04 Entire Agreement. This Agreement, including the documents referred to herein or delivered pursuant hereto, contains the entire agreement and understanding of the parties with respect to its subject matter. This Agreement supersedes all prior arrangements and understandings between the parties, both written and oral, with respect to its subject matter other than the Confidentiality Agreements.
