WHEREAS, the Boards of Directors of NPB and AMI each have determined that the acquisition of AMI by NPB is in the best interests of their respective companies and stockholders and presents an opportunity for their respective companies to achieve long-term strategic and financial benefits, and accordingly have agreed to effect the merger provided for herein upon the terms and subject to the conditions set forth herein; and WHEREAS, for federal income tax purposes, it is intended that the merger contemplated herein shall qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), and for financial accounting purposes shall be accounted for as a pooling of interests. NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, the parties hereto agree as follows: ARTICLE I THE MERGER 1.1 The Merger. Subject to the terms and conditions of this Agreement, at the Effective Time (as defined in Section 1.2 hereof), AMI shall be merged with and into NPB, NPB shall be the surviving corporation (the "Surviving Corporation") and the separate existence of AMI shall thereupon cease (the "Merger"). The Merger shall have the effects set forth in Section 259 of the General Corporation Law of the State of Delaware (the "DGCL") and Section 302A.641 of the Minnesota Business Corporations Act ("MBCA"). 1.2 Effective Time of the Merger. The Merger shall become effective when a properly executed Certificate of Merger is duly filed with the Secretary of State of the State of Delaware and the Secretary of State of the State of Minnesota, which filings shall be made as soon as practicable after the closing of the transactions contemplated by this Agreement in accordance with Section 3.6 hereof upon satisfaction or waiver of the conditions set forth in Article VIII. When used in this Agreement, the term "Effective Time" shall mean the date and time at which both such Certificates of Merger have been so filed. ARTICLE II THE SURVIVING CORPORATION 2.1 Certificate of Incorporation. The Certificate of Incorporation of NPB shall be the Certificate of Incorporation of the Surviving Corporation, until duly amended in accordance with the terms thereof and the DGCL. 2.2 Bylaws. The Bylaws of NPB as in effect at the Effective Time shall be the Bylaws of the Surviving Corporation, until duly amended in accordance with the terms thereof and the DGCL. 2.3 Directors and Officers of Surviving Corporation. (a) The directors of NPB shall be the directors of the Surviving Corporation and shall hold office from the Effective Time until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, or as otherwise provided by law. (b) The officers of NPB at the Effective Time shall be the initial officers of the Surviving Corporation and shall hold office from the Effective Time until removed or until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, or as otherwise provided by law. A-1 7 ARTICLE III CONVERSION OF SHARES 3.1 Exchange Ratio. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof: (a) Subject to Section 3.4 hereof, each share of common stock, no par value ("AMI Common Stock"), of AMI that is issued and outstanding immediately prior to the Effective Time (other than shares of AMI Common Stock to be canceled pursuant to Section 3.1(b)) shall be converted at the Effective Time into the right to receive that fraction of a share of NPB of common stock, par value $0.001 per share, of NPB equal to the Exchange Ratio (as defined below) together with the corresponding preferred stock purchase rights associated with such shares of NPB common stock in accordance with the NPB Rights Agreement (as defined in Section 5.2(b)) ("NPB Common Stock"). All references herein to NPB Common Stock, including the shares issuable in the Merger, shall be deemed to include the associated preferred stock purchase rights, except where the context otherwise clearly requires. The exchange ratio for the Merger ("Exchange Ratio") shall be calculated as follows: 1. If the Closing Market Value (as defined below) is greater than or equal to $23.14 and less than or equal to $26.61, the Exchange Ratio will be .432; 2. If the Closing Market Value is greater than $26.61, the Exchange Ratio will be the quotient of (A) $11.50 divided by (B) the Closing Market Value, rounded to the nearest one-one thousandth of a share; 3. If the Closing Market Value is less than $23.14 and greater than or equal to $22.75, the Exchange Ratio will be the quotient of (A) $10.00 divided by (B) the Closing Market Value, rounded to the nearest one-one thousandth of a share; and 4. If the Closing Market Value is less than $22.75, the Exchange Ratio will be .440. For purposes of this Agreement, the "Closing Market Value" shall mean the average of the closing prices of NPB Common Stock as reported by the Nasdaq National Market for the ten trading days ending on the fifth trading day prior to the AMI shareholders meeting referred to in Section 7.4. At the Effective Time, all such shares of AMI Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each certificate previously representing any such shares of AMI Common Stock (a "Certificate") shall thereafter represent the right to receive (i) the number of whole shares of NPB Common Stock and (ii) cash in lieu of fractional shares into which the shares of AMI Common Stock represented by such Certificate have been converted pursuant to Section 3.2 and Section 3.4 hereof. Each Certificate shall be exchanged for (x) certificates representing whole shares of NPB Common Stock, and (y) cash in lieu of fractional shares, issued in consideration therefor upon the surrender of such Certificate in accordance with the provisions hereof, without interest thereon. If prior to the Effective Time NPB should split or combine the shares of NPB Common Stock, or pay a stock dividend or other stock distribution, in, or in exchange of, shares of NPB Common Stock, or engage in any similar transaction, then the Exchange Ratio will be appropriately adjusted to reflect such split, combination, dividend, exchange or other distribution or similar transaction. At the Effective Time, all stock options, warrants and convertible securities to purchase AMI Common Stock then outstanding shall be assumed by NPB in accordance with Section 7.8. (b) Each share of AMI Common Stock held in the treasury of AMI and each share of AMI Common Stock held by NPB or any subsidiary of NPB immediately prior to the Effective Time shall be canceled and retired and cease to exist, and no shares of NPB Common Stock shall be issued in exchange therefor. All shares of NPB Common Stock owned by AMI or any subsidiary of AMI shall become treasury stock of NPB. 3.2 Exchange of Shares. (a) Prior to the Effective Time, NPB shall select, and enter into an agreement (in form and substance reasonably satisfactory to AMI) with, a bank or trust company to act as Exchange Agent hereunder (the A-2 8 "Exchange Agent"). Within a reasonable period of time after the Effective Time, NPB shall make available, and each holder of shares of AMI Common Stock (other than Excluded Shares) will be entitled to receive upon surrender to the Exchange Agent of one or more Certificates, certificates representing the number of whole shares of NPB Common Stock and cash in lieu of fractional shares into which such shares of AMI Common Stock are converted in the Merger. The shares of NPB Common Stock into which the shares of AMI Common Stock shall be converted in the Merger shall be deemed to have been issued at the Effective Time. (b) As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of AMI Common Stock (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as NPB may reasonably specify that are not inconsistent with the terms of this Agreement) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of NPB Common Stock. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor (i) a certificate representing that number of whole shares of NPB Common Stock and (ii) a check representing the amount of cash in lieu of fractional shares, if any, which such holder has the right to receive in respect of the Certificate so surrendered pursuant to the provisions of this Article III. (c) In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, NPB will issue or cause to be issued in exchange for such lost, stolen or destroyed Certificate the number of whole shares of NPB Common Stock and cash in lieu of fractional shares into which the shares of AMI Common Stock represented by the Certificate are converted in the Merger in accordance with this Article III. When authorizing such issuance in exchange therefor, NPB may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificate to give NPB a bond in such sum as it may direct as indemnity, or such other form of indemnity, as it shall direct, against any claim that may be made against NPB with respect to the Certificate alleged to have been lost, stolen or destroyed. 3.3 Dividends; Transfer Taxes. No dividends that are declared on shares of NPB Common Stock after the Effective Time will be paid to persons entitled to receive certificates representing shares of NPB Common Stock until such persons surrender their Certificates. Upon such surrender, there shall be paid to the person in whose name the certificates representing such shares of NPB Common Stock shall be issued, any dividends which shall have become payable with respect to such shares of NPB Common Stock between the Effective Time and the time of such surrender. In no event shall the person entitled to receive such dividends be entitled to receive interest on such dividends. If any certificates for any shares of NPB Common Stock are to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the person requesting such exchange shall (a) pay to the Exchange Agent any transfer or other taxes required by reason of the issuance of certificates for such shares of NPB Common Stock in a name other than that of the registered holder of the Certificate surrendered or (b) establish to the satisfaction of the Exchange Agent that such tax has been paid or is not applicable. Notwithstanding anything in this Agreement to the contrary, neither the Exchange Agent nor any party hereto shall be liable to a holder of shares of AMI Common Stock for any shares of NPB Common Stock or dividends thereon or, in accordance with Section 3.4 hereof, the cash payment for fractional interests, delivered to a public official pursuant to applicable escheat laws following the passage of time specified therein. 3.4 No Fractional Shares. No fractional shares of NPB Common Stock shall be issued pursuant to the Merger. In lieu of the issuance of any such fractional share of NPB Common Stock pursuant to Section 3.2, cash adjustments will be paid to holders in respect of any fractional share of NPB Common Stock that would otherwise be issuable. The amount of such adjustment shall be the product of such fraction of a share of NPB Common Stock multiplied by the closing sales price per share of NPB Common Stock on the Nasdaq National Market on the business day immediately preceding the Closing Date. A-3 9 3.5 Closing of AMI Transfer Books. At the Effective Time, the stock transfer books of AMI shall be closed and no transfer of shares of AMI Common Stock shall thereafter be made. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they shall be canceled and exchanged for certificates representing shares of NPB Common Stock or cash in lieu of fractional shares in accordance with the terms hereof. At and after the Effective Time, the holders of shares of AMI Common Stock to be exchanged for shares of NPB Common Stock pursuant to this Agreement shall cease to have any rights as stockholders of AMI, except for the right to surrender such Certificates in exchange for shares of NPB Common Stock as provided hereunder or such dissenters' rights as are provided under applicable law. 3.6 Closing. The closing of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of Morrison & Foerster, 19900 MacArthur Boulevard, 12th Floor, Irvine, California 92765 at 9:00 a.m., local time, on the first business day (the "Closing Date") following the date on which the AMI stockholders' meeting referred to in Section 7.4 hereof shall have occurred; provided that if all of the other conditions set forth in Article VIII hereof are not satisfied or waived at such date the Closing Date shall be the business day following the day on which all such conditions have been satisfied or waived, or at such other date, time and place as NPB and AMI shall agree. 3.7 Supplementary Action. If at any time after the Effective Time, any further assignments or assurances in law or any other things are necessary or desirable to vest or to perfect or confirm of record in the Surviving Corporation the title to any property or rights of AMI, or otherwise to carry out the provisions of this Agreement, the officers and directors of the Surviving Corporation are hereby authorized and empowered on behalf of AMI in the name of and on behalf of AMI to execute and deliver any and all things necessary or proper to vest or to perfect or confirm title to such property or rights in the Surviving Corporation, and otherwise to carry out the purposes and provisions of this Agreement. 3.8 Dissenting Shares. If holders of AMI Common Stock are entitled to dissent from the Merger and demand appraisal of any such AMI Common Stock under applicable law (each person electing to exercise such rights, a "Dissenting Holder"), any shares of AMI Common Stock held by a Dissenting Holder as to which appraisal has been so demanded ("Excluded Shares") shall not be converted as described in Section 3.1, but shall from and after the Effective Time represent only the right to receive such consideration as may be determined to be due such Dissenting Holder pursuant to applicable law; provided, however, that each share of AMI Common Stock held by a Dissenting Holder who shall, after the Effective Time, withdraw its demand for appraisal or lose its rights of appraisal with respect to such shares of AMI Common Stock, in either case pursuant to applicable law, shall not be deemed an Excluded Share, but shall be deemed to be converted, as of the Effective Time, into the right to receive NPB Common Stock in accordance with the Exchange Ratio. ARTICLE IV REPRESENTATIONS AND WARRANTIES OF AMI As used in this Agreement, (a) the term "Material Adverse Effect" means, with respect to AMI or NPB, as the case may be, a material adverse effect on the business, assets, operations or results of operation or condition (financial or otherwise) of AMI or NPB, in each case including its subsidiaries taken as a whole, or on its ability to perform its obligations hereunder and (b) the word "subsidiary" when used with respect to any party means any corporation or other organization, whether incorporated or unincorporated, of which such party or any other subsidiary of such party is a general partner (excluding partnerships the general partnership interests of which held by such party or any subsidiary of such party do not have a majority of the voting interests in such partnership) or of which at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the Board of Directors or others performing similar functions with respect to such corporations or other organizations is directly or indirectly owned or controlled by such party and/or by any one or more of the subsidiaries. A-4 10 Except as set forth in the disclosure letter delivered to NPB at or prior to the execution of this Agreement ("AMI Disclosure Schedule"), AMI represents and warrants to NPB as follows: 4.1 Organization. AMI is a corporation duly organized, validly existing and in good standing under the laws of the State of Minnesota and has the corporate power to carry on its business as it is now being conducted. AMI is duly qualified as a foreign corporation to do business, and is in good standing in each jurisdiction where the character of its properties owned or held under lease or the nature of its activities makes such qualification necessary, except where the failure to be so qualified will not in the aggregate have a Material Adverse Effect. Each subsidiary of AMI is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization, has the corporate power to carry on its business as it is now being conducted and is duly qualified as a foreign corporation to do business, and is in good standing in each jurisdiction where the character of its properties owned or held under lease or the nature of its activities makes such qualification necessary, except where the failure to be so duly organized, validly existing and in good standing, to have such corporate power or to be so qualified will not in the aggregate have a Material Adverse Effect. AMI has delivered to NPB or its counsel complete and correct copies of its and its subsidiaries' Articles of Incorporation and Bylaws. 4.2 Capitalization. (a) As of September 1, 1996, the authorized capital stock of AMI consists of 15,000,000 shares of AMI Common Stock. As of September 1, 1996, 4,950,842 shares of AMI Common Stock were issued and outstanding, stock options to acquire 1,177,400 shares of AMI Common Stock (the "AMI Stock Options") were outstanding under all stock option plans of AMI, 417,955 additional shares of AMI Common Stock were reserved for issuance under AMI's stock option plans. No changes have occurred in such capitalization since September 1, 1996 that, in the aggregate, would be material to AMI, except for option exercises in the ordinary course of business. All of the issued and outstanding shares of AMI Common Stock are validly issued, fully paid, nonassessable and free of preemptive rights or similar rights created by statute, the Articles of Incorporation or Bylaws of AMI or any agreement to which AMI or any of its subsidiaries is a party or by which AMI or any of its subsidiaries is bound. Since September 1, 1996, AMI has not issued any shares of its capital stock, except upon the exercise of AMI Stock Options. (b) Except as set forth in Section 4.2, there are not now, and at the Effective Time there will not be, any shares of capital stock of AMI issued or outstanding or any options, warrants, subscriptions, calls, rights, convertible securities or other agreements or commitments obligating AMI to issue, transfer or sell any shares of its capital stock. As of the date hereof, no bonds, debentures, notes or other indebtedness having the right to vote (or convertible into or exercisable for securities having the right to vote) on any matters on which stockholders may vote ("Voting Debt") of AMI were issued or outstanding, nor will there be any issued or outstanding at the Effective Time. All outstanding shares of the capital stock of AMI's subsidiaries are validly issued, fully paid, non-assessable and owned by AMI or one of its subsidiaries free and clear of any liens, security interest, pledges, agreements, claims, charges or encumbrances of any nature whatsoever. There are no voting trust or other agreements or understandings to which AMI is a party with respect to the voting of the capital stock of AMI or any of its subsidiaries. None of AMI or its subsidiaries is required to redeem, repurchase or otherwise acquire shares of capital stock of AMI, or any of its subsidiaries, respectively, as a result of the transactions contemplated by this Agreement. Immediately after the Effective Time, there will be no option, warrant, call, right or agreement obligating AMI or any subsidiary of AMI to issue, deliver or sell, or cause to be issued, delivered or sold, any shares of AMI Common Stock or any Voting Debt, or obligating AMI or any subsidiary of AMI to grant, extend or enter into any such option, warrant, call, right or agreement. 4.3 Authority Relative to this Agreement. AMI has the corporate power to enter into this Agreement and to carry out its obligations hereunder. The execution and delivery of this Agreement by AMI and the consummation by AMI of the transactions contemplated hereby have been duly authorized by AMI's Board of Directors and, except for the favorable vote of a majority of the shares of outstanding capital stock of AMI entitled to vote thereon in accordance with applicable law, no other corporate proceedings on the part of AMI are necessary to approve this Agreement or the transactions contemplated hereby. This Agreement has been A-5 11 duly and validly executed and delivered by AMI and constitutes a valid and binding agreement of AMI, enforceable against AMI in accordance with its terms. 4.4 Consents and Approvals; No Violations. Except for applicable requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR Act"), the Securities Act of 1933, as amended (the "Securities Act"), the Securities Exchange Act of 1934, as amended (the "Exchange Act"), state or foreign laws relating to takeovers, if applicable, state securities or blue sky laws, and the filing and recordation of a Certificate of Merger as required by the DGCL and MBCA, no filing with, and no permit, authorization, consent or approval of, any public or governmental body or authority is necessary for the consummation by AMI of the transactions contemplated by this Agreement, except where a failure to make such filing or to obtain such permit, registration, authorization, consent or approval will not in the aggregate have a Material Adverse Effect. Neither the execution and delivery of this Agreement by AMI, nor the consummation by AMI of the transactions contemplated hereby, nor compliance by AMI with any of the provisions hereof, will (a) conflict with or result in any breach of any provisions of the Articles of Incorporation or Bylaws of AMI or any of its subsidiaries, (b) result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation, acceleration or change in the award, grant, vesting or determination) under, or give rise to creation of any lien, charge, security interest or encumbrance upon any of the respective properties or assets of AMI or any of its subsidiaries under, any of the terms, conditions or provisions of any note, bond, mortgage, indenture, deed of trust, license, contract, lease, agreement, arrangement or other instrument or obligation to which AMI or any of its subsidiaries is a party or by which any of them or any of their properties or assets may be bound or affected or (c) violate any order, writ, injunction, decree, statute, rule or regulation of any court or government authority applicable to AMI, any of its subsidiaries or any of their properties or assets, except in the case of clauses (b) and (c) for violations, breaches, defaults (or rights of termination, cancellation, acceleration or change), liens, charges, security interests or encumbrances which would not in the aggregate have a Material Adverse Effect. 4.5 Reports and Financial Statements. AMI has filed all reports required to be filed with the Securities and Exchange Commission (the "SEC") pursuant to the Exchange Act since May 1980 including, without limitation, Annual Reports on Form 10-K for the years ended April 30, 1994, April 30, 1995 and April 30, 1996 (all such reports and amendments thereto, collectively, the "AMI SEC Reports"), and has previously furnished or made available to NPB true and complete copies of all AMI SEC Reports filed with respect to periods beginning after April 30, 1992 (including any exhibits thereto) and will promptly deliver to NPB any AMI SEC Reports filed between the date hereof and the Effective Time. None of such AMI SEC Reports, as of their respective dates (as amended through the date hereof), contained or, with respect to the AMI SEC Reports filed after the date hereof, will contain any untrue statement of a material fact or omitted or, with respect to the AMI SEC Reports filed after the date hereof, will omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of the balance sheets (including the related notes) included in the AMI SEC Reports fairly presents the consolidated financial position of AMI and its subsidiaries as of the date thereof, and the other related statements (including the related notes) included therein fairly present the results of operations and the changes in cash flows of AMI and its subsidiaries for the respective periods set forth therein, all in conformity with generally accepted accounting principles consistently applied during the periods involved, except as otherwise noted therein and subject, in the case of the unaudited interim financial statements, to (a) normal year end adjustments which would not in the aggregate be material in amount or effect and (b) the permitted exclusion of all footnotes that would otherwise be required by generally acceptable accounting principles. 4.6 Absence of Certain Changes or Events. Except as disclosed in the AMI SEC Reports filed prior to the date of this Agreement, since April 30, 1996, neither AMI nor any of its subsidiaries: (a) has taken any of the actions prohibited in Section 6.1 or Section 6.2 hereof; (b) has incurred any material liability, except in the ordinary course of its business and consistent with past practices; (c) has suffered any change, or any event involving a prospective change, in its business, assets, financial condition or results of operation which has had, or is reasonably likely to have, in the aggregate a Material Adverse Effect (other than as a result of changes or proposed changes in federal or state health care (including health care reimbursement) laws or regulations of A-6 12 general applicability or interpretations thereof, changes in generally accepted accounting principles and changes that could, under the circumstances, reasonably have been anticipated in light of disclosures made in writing by AMI to NPB prior to the execution of this Agreement); or (d) subsequent to the date hereof, except as permitted by Section 6.1 or Section 6.2 hereof, will conduct its business and operations other than in the ordinary course of business and consistent with past practices. 4.7 Information in Registration Statement and Proxy Statement.

A copy of each AMI Plan as currently in effect and, if applicable, the most recent Annual Report, Actuarial Report or Valuation, Summary Plan Description, Trust Agreement and a Determination Letter issued by the IRS for each AMI Plan have heretofore been delivered to NPB or its counsel. Neither AMI nor any trade or business, whether or not incorporated (an "ERISA Affiliate"), which together with AMI would be deemed a "single employer" within the meaning of Section 4001 of ERISA, has maintained or contributed to any plan subject to Title IV of ERISA or Section 412 of the Code (including any "multiemployer plan," as defined in Section 3(37) of ERISA ("Multiemployer Plan")) during the six calendar years preceding the date of this Agreement.

Nothing has occurred since the date of the Internal Revenue Service's favorable determination letter that could adversely affect the qualification of the AMI Plan and its related trust, except such adverse effects as would not in the aggregate constitute a Material Adverse Effect. AMI and each ERISA Affiliate of AMI have timely and properly applied for a written determination by the Internal Revenue Service on the qualification of each such AMI Plan and its related trust under Section 401(a) of the Code, as amended by the Tax Reform Act of 1986 and subsequent legislation enacted through the date hereof, and Section 501 of the Code.

(j) Neither AMI nor any ERISA Affiliate of AMI has any liability or is threatened with any liability (whether joint or several) (i) for the termination of any single employer plan under Sections 4062 or 4064 of ERISA or any multiple employer plan under Section 4063 of ERISA, (ii) for any lien imposed under Section 302(f) of ERISA or Section 412(n) of the Code, (iii) for any interest payments required under Section 302(e) of ERISA or Section 412(m) of the Code, (iv) for any excise tax imposed by Sections 4971, 4975, 4976, 4977 or 4979 of the Code, (v) for any minimum funding contributions under Section 302(c)(11) of ERISA or Section 412(c)(11) of the Code, (vi) to a fine under Section 502 of ERISA, or (vii) for any transaction within the meaning of Section 4069 of ERISA. (k) AMI has not incurred any withdrawal liability with respect to any Multiemployer Plan within the meaning of Sections 4201 and 4204 of ERISA, and no liabilities exist with respect to withdrawals from any Multiemployer Plans which could subject AMI to any controlled group liability under Section 4001(b) of ERISA. (l) All of the AMI Plans, to the extent applicable, are in compliance with the continuation of group health coverage provisions contained in Section 4980B of the Code and Section 601 through 608 of ERISA, except for such instances of noncompliance which would not in the aggregate have a Material Adverse Effect. 4.11 Tax Matters.

NPB is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has the corporate power to carry on its business as it is now being conducted. NPB is duly qualified as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of its properties owned or held under lease or the nature of its activities makes such qualification necessary, except where the failure to be so qualified will not in the aggregate have a Material Adverse Effect.

NPB has delivered to AMI or its counsel complete and correct copies of its Certificate of Incorporation and Bylaws. 5.2 Capitalization.

To the extent such representations permit omissions of items otherwise required to be disclosed because they are not material or do not or would not have a Material Adverse Effect on NPB, such omissions in the aggregate would not and do not have a Material Adverse Effect on NPB.
