R E C I T A L S A. The Boards of Directors of IUB and PTC each have determined that a business combination involving the merger of PTC with and into IUB is in the best interests of their respective companies and their respective companies' shareholders, communities, customers and other constituencies, and presents an opportunity for IUB and PTC and their respective shareholders to achieve long-term strategic and financial benefits, and accordingly have agreed to effect the merger provided for herein (the "Merger") upon the terms and subject to the conditions set forth herein. B. IUB and PTC desire to make certain representations, warranties, covenants and agreements in connection with the Merger and to prescribe various conditions to the Merger. C. For federal income tax purposes, it is intended that the Merger qualify as a reorganization under the provisions of Section 368 of the Internal Revenue Code of 1986, as amended (the "Code"). D. It is intended that the Merger shall be recorded for accounting and financial reporting purposes as a pooling of interests. A G R E E M E N T NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements contained herein, the parties hereto agree as follows: ARTICLE I THE MERGER 1.1 EFFECTIVE TIME OF THE MERGER. Subject to the provisions of this Agreement, articles of merger (the "Articles of Merger") shall be duly executed and acknowledged by the Surviving Corporation (as defined in Section l.3) and thereafter delivered to the Secretary of State of the State of Indiana, for filing, as provided in the Indiana Business Corporation Law (the "IBCL"), as soon as practicable on or after the Closing Date (as defined in Section 1.2). The Merger shall become effective upon the filing of the Articles of Merger with the Secretary of State of the State of Indiana or at such time thereafter as is provided in the Articles of Merger (the "Effective Time"). 1.2 CLOSING. The closing of the Merger (the "Closing") will take place at 10:00 a.m. on a date to be specified by the parties, which shall be the first day which is five business days after satisfaction of the latest to occur of the conditions set forth in Sections 6.1, 6.2(b) and 6.3(b) (other than delivery of the officers' certificates referred to in Sections 6.2(b) and 6.3(b)), provided that the other closing conditions set forth in Article VI have been met or waived as provided in Article VI at or prior to the Closing (the "Closing Date"), at the offices of Henderson, Daily, Withrow & DeVoe, 2600 One Indiana Square, Indianapolis, Indiana 46204, unless another time, date or place is agreed to by the parties hereto. 1.3 EFFECTS OF THE MERGER. At the Effective Time, (a) the separate existence of PTC shall cease and PTC shall be merged with and into IUB, (b) the articles of incorporation of IUB as in effect immediately prior to the Effective Time shall be the articles of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law and (c) the bylaws of IUB as in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law. As used in this Agreement, "Surviving Corporation" shall mean IUB. At and after the Effective Time, the Merger will have the effects set forth in Section 23-1-40-6 of the IBCL. ARTICLE II EFFECT OF THE MERGER ON THE STOCK OF PTC; EXCHANGE OF CERTIFICATES 2.1 EFFECT ON CAPITAL STOCK. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any common stock of PTC ("PTC Common Stock"): (a) CANCELLATION OF CERTAIN SHARES. All PTC Common Stock that is owned by PTC as treasury stock or by IUB or by any wholly owned Subsidiary of PTC or IUB (other than shares in trust accounts, managed accounts and the like that are beneficially owned by third parties (any such shares, "trust account shares")) shall be canceled and shall cease to exist and no shares of common stock of IUB or other consideration shall be delivered in exchange therefor. (b) CONVERSION OF PTC COMMON STOCK. Each of the shares of PTC Common Stock issued and outstanding immediately prior to the Effective Time of the Merger shall be converted into 1.075 (such number being referred to as the "Conversion Ratio") fully paid and non-assessable shares of common stock of IUB, without par value ("IUB Common Stock"), all in accordance with Section 2.2. (c) DISSENTING SHARES. Notwithstanding any other provisions of this Agreement to the contrary, PTC Common Stock that is outstanding immediately prior to the Effective Time and which is held by shareholders who shall not have voted in favor of the Merger or consented thereto in writing and who shall have properly delivered in writing notice of intent to demand payment for such shares in accordance with Section 23-1-44-11 of the IBCL and who thereafter shall have properly demanded payment and otherwise complied with the provisions of Section 23-1-44-13 of the IBCL (collectively, the "Dissenting Shares") shall not be converted into or represent the right to receive the consideration provided in Section 2.1(b). Such shareholders ("Dissenting Holders") shall be entitled to receive payment of the fair value of such PTC Common Stock held by them in accordance with the provisions of Section 23-1-44-15 or 23-1-44-19 of the IBCL, as applicable, except that all Dissenting Shares held by shareholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to receive payment of the fair value of such PTC Common Stock under such provisions of the IBCL shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the consideration provided in Section 2.1(b), without any interest thereon, upon surrender of the certificate or certificates that formerly evidenced such PTC Common Stock in accordance with Section 2.2. (d) ADJUSTMENT TO CONVERSION RATIO. If, prior to the Effective Time of the Merger, IUB shall pay a dividend in, subdivide, combine into a smaller number of shares or issue by reclassification of its shares any IUB Common Stock, the Conversion Ratio shall be multiplied by a fraction, the numerator of which shall be the number of shares of IUB Common Stock outstanding immediately after, and the denominator of which shall be the number of such shares outstanding immediately before, the occurrence of such event, and the product shall be the Conversion Ratio for purposes of Section 2.1(b). 2.2 EXCHANGE OF CERTIFICATES. (a) EXCHANGE AGENT. IUB shall authorize a commercial bank (or such other person or persons as shall be acceptable to PTC) to act as exchange agent hereunder (the "Exchange Agent"). As soon as practicable, but not later than three business days after the Effective Time, IUB shall deposit with the Exchange Agent, in trust for the holders of certificates which immediately prior to the Effective Time represented PTC Common Stock converted in the Merger ("PTC Certificates"), certificates representing the shares of IUB Common Stock (such shares of IUB Common Stock, together with any dividends or distributions with respect thereto in accordance with Section 2.2(c), being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.1(b) (less, if applicable, the 2 number of Excess Shares that will not be issued and sold because of payment for fractional shares being made pursuant to Section 2.2(e)(iv)) in exchange for the outstanding PTC Common Stock (the "IUB Certificates"). (b) EXCHANGE PROCEDURES. (i) As soon as practicable after the Effective Time, the Exchange Agent shall mail to each recordholder of a PTC Certificate a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the PTC Certificates shall pass, only upon actual delivery thereof to the Exchange Agent and shall contain instructions for use in effecting the surrender of PTC Certificates in exchange for the consideration described in the next sentence). Upon surrender for cancellation to the Exchange Agent of all PTC Certificates held by any recordholder of PTC Certificates, together with such letter of transmittal duly executed, such holder shall be entitled to receive in exchange therefor an IUB Certificate(s) representing the number of whole shares of IUB Common Stock into which the PTC Common Stock represented by the surrendered PTC Certificate(s) shall have been converted at the Effective Time pursuant to this Article II, cash in lieu of any fractional share of IUB Common Stock in accordance with Section 2.2(e) and certain dividends and other distributions in accordance with Section 2.2(c), and the PTC Certificate(s) so surrendered shall forthwith be canceled; PROVIDED, HOWEVER, that PTC Certificates surrendered for exchange by any person constituting an "affiliate" of PTC for purposes of Rule 145(c) under the Securities Act of 1933, as amended (the "Securities Act"), shall not be exchanged for IUB Certificates until IUB has received a written agreement from such person as provided in Section 5.3. (ii) Until PTC Certificates have been surrendered and exchanged for IUB Certificates as herein provided, each outstanding PTC Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender an IUB Certificate(s) representing a whole number of shares of IUB Common Stock and cash in lieu of any fractional share as contemplated by this Section 2.2. No transfer taxes shall be payable in connection with any such exchange, except that if any IUB Certificate (or any check representing cash in lieu of a fractional share) is to be issued in the name other than that in which the PTC Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the person requesting such exchange shall pay to the Exchange Agent any transfer or other taxes required by reason of the issuance of the IUB Certificate (or check) in a name other than that of the registered holder of the PTC Certificate, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not applicable. IUB or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of PTC Common Stock such amounts as IUB or the Exchange Agent are required to deduct and withhold under the Code, or any provision of state, local or foreign tax law, with respect to the making of such payment. To the extent that amounts are so withheld by IUB or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of PTC Common Stock in respect of whom such deduction and withholding was made by IUB or the Exchange Agent. If outstanding PTC Certificates are not surrendered prior to six years after the Effective Time of the Merger (or, in any particular case, prior to such earlier date on which dividends and other distributions, if any, described above would otherwise escheat to or become the property of any governmental unit or agency), the amount of dividends and other distributions, if any, that have become payable and that thereafter become payable on IUB Common Stock evidenced by such PTC Certificates as provided herein shall, to the extent permitted by applicable law, become the property of IUB (and, to the extent not in its possession, shall be paid over to it), free and clear of all claims or interest of any person previously entitled thereto. 3 (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or other distributions declared or made after the Effective Time with respect to IUB Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered PTC Certificate with respect to the IUB Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e), until the holder of such PTC Certificate shall surrender it. Subject to the effect of applicable laws, following surrender of any such PTC Certificate, there shall be paid to the holder of the IUB Certificate representing whole shares of IUB Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender or promptly thereafter as is practicable, the amount of any cash payable with respect to a fractional share of IUB Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole number of shares of IUB Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole number of shares of IUB Common Stock. (d) NO FURTHER OWNERSHIP RIGHTS IN PTC COMMON STOCK. All IUB Common Stock issued upon conversion of PTC Common Stock in accordance with the terms hereof (including any cash paid pursuant to Section 2.2(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such PTC Common Stock, SUBJECT, HOWEVER, to the Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time that may have been declared or made by PTC on PTC Common Stock in accordance with the terms of this Agreement on or prior to the Effective Time and which remain unpaid at the Effective Time. At the Effective Time, the stock transfer books of PTC shall be closed to holders of PTC Common Stock immediately prior to the Effective Time and no transfer of PTC Common Stock by any such holder shall thereafter be made or recognized. If, after the Effective Time, PTC Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II. (e) NO FRACTIONAL SHARES. (i) No fractional share of IUB Common Stock and no certificate or scrip therefor, or other evidence of ownership thereof, will be issued, and no right to receive cash in lieu thereof shall entitle the holder thereof to any voting or other rights of a holder of shares or fractional share interests. (ii) As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (i) the number of shares of IUB Common Stock delivered to the Exchange Agent by IUB pursuant to Section 2.2(a) over (ii) the aggregate number of whole shares of IUB Common Stock to be distributed to holders of PTC Common Stock pursuant to Section 2.2(b) (such excess being herein called the "Excess Shares"). As promptly as practicable after such determination of the number of Excess Shares, the Exchange Agent, as agent for the holders of PTC Common Stock, shall sell the Excess Shares in the over-the-counter market at then prevailing prices, all in the manner provided in subparagraph (iii) of this Section 2.2(e). (iii) The sale of the Excess Shares by the Exchange Agent shall be executed in the over-the-counter market through one or more market makers for IUB Common Stock and shall be executed in round lots to the extent practicable. Until the net proceeds of such sale or sales have been distributed to the holders of PTC Common Stock, the Exchange Agent will hold such proceeds in trust for the holders of PTC Common Stock (the "Excess Shares Trust"). IUB shall pay all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent, incurred in connection with such sale of the Excess Shares. The Exchange Agent shall determine the portion of the Excess Shares Trust to 4 which each holder of PTC Common Stock shall be entitled, if any, by multiplying the amount of the aggregate net proceeds comprising the Excess Shares Trust by a fraction, the numerator of which is the amount of the fractional share interest to which such holder of PTC Common Stock is entitled (after taking into account all shares of PTC Common Stock then held by such holder) and the denominator of which is the aggregate amount of fractional share interests to which all holders of PTC Common Stock are entitled. (iv) Notwithstanding the provisions of subparagraphs (ii) and (iii) above, if the parties shall so agree in writing prior to the Closing, then in lieu of the issuance and sale of Excess Shares and the making of the payments contemplated in said subparagraphs, each holder of PTC Common Stock shall be paid an amount in cash equal to the product obtained by multiplying the fractional share interest to which such holder (after taking into account all shares of PTC Common Stock then held by such holder) would otherwise be entitled by the midpoint between the highest "bid" and lowest "asked" price for a share of IUB Common Stock in the over-the-counter market for the business day immediately preceding the Closing Date, and, in such case, all references herein to the cash proceeds of the sale of the Excess Shares and similar references shall be deemed to mean and refer to the payments calculated as set forth in this subparagraph (iv). (v) As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of PTC Common Stock with respect to any fractional share interests, the Exchange Agent shall make available such amounts to such holders of PTC Common Stock subject to and in accordance with the terms of Section 2.2(b). (f) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund which remains undistributed to the shareholders of PTC for six months after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any shareholders of PTC who have not theretofore complied with this Article II shall thereafter look only to IUB for payment of their claim for IUB Common Stock, any cash in lieu of fractional shares of IUB Common Stock and any dividends or distributions with respect to IUB Common Stock. (g) NO LIABILITY. Neither IUB, PTC nor the Surviving Corporation shall be liable to any holder of PTC Common Stock for any amount paid or property delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as set forth in the PTC Letter or disclosed in any PTC SEC Document filed prior to the date hereof, since December 31, 1996, neither PTC nor any Subsidiary has incurred any material liability or obligation (indirect, direct or contingent), except in the ordinary course of its business consistent with past practices, taken any of the prohibited actions set forth in Section 4.1, or suffered any change, or any event involving a prospective change, in its business, financial condition or results of operations that has had, or is reasonably likely to have, a Material Adverse Effect on PTC. (f) ABSENCE OF UNDISCLOSED LIABILITIES. Except as set forth in the PTC Letter or disclosed in any PTC SEC Document filed prior to the date hereof, neither PTC nor any Subsidiary has any obligations or liabilities (contingent or otherwise) that might reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on PTC.

Except as set forth in the PTC Letter, neither PTC, any of its Subsidiaries, nor any properties presently or previously owned or operated by PTC or any of its Subsidiaries has been or is in violation of or liable under any Environmental Law (as hereinafter defined). There are no actions, suits or proceedings, or demands, claims, notices or investigations (including notices, demand letters or requests for information from any environmental agency) instituted or pending, or to the knowledge of PTC, threatened, relating to the liability of any properties owned or operated by PTC or any of its Subsidiaries under any Environmental Law. "Environmental Law" means any federal, state or local law, statute, ordinance, rule, regulation, code, license, permit, authorization, approval, consent, order, judgment, decree, injunction or agreement between PTC or IUB, as the case may be, and any Governmental Entity relating to (i) the protection, preservation or restoration of the environment (including, without limitation, air, water vapor, surface water, ground water, drinking water supply, surface soil, subsurface soil, plant and animal life or any other natural resource), and/or (ii) the use, storage, recycling, treatment, generation, transportation, processing, handling, labeling, production, release or disposal of any substance presently listed, defined, designated or classified as hazardous, toxic, radioactive or dangerous, or otherwise regulated, whether by type or by quantity, including any material containing any such substance as a component; and includes, without limitation, the Resource Conservation and Recovery Act, the Clean Air Act, the Federal Water Pollution Control Act, the Toxic Substances Control Act and the Comprehensive Environmental Response, Compensation and Liability Act. (i) INFORMATION SUPPLIED. None of the information supplied or to be supplied by PTC for inclusion in (i) the S-4 to be filed with the SEC by IUB in connection with the issuance of IUB Common Stock in the Merger will, at the time the S-4 is filed with the SEC and at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any 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, and (ii) the Proxy Statement to be filed with the SEC in connection with the meeting of shareholders will, at the dates of mailing to shareholders of IUB and PTC and at the times of the meetings of shareholders of IUB and PTC to be held in connection with the Merger, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Proxy Statement (except for such portions thereof that relate only to IUB) will comply as to form in all material respects with the provisions of the Exchange Act and the rules and regulations thereunder. The information set forth in the PTC Letter by PTC for purposes of this Agreement is true and accurate in all material respects. (j) NO DEFAULT. Except as set forth in the PTC Letter, no Violation exists on the part of PTC or any Subsidiary with respect to any term, condition or provision of (i) its articles of incorporation or bylaws, (ii) any note, mortgage, indenture, other evidence of indebtedness, guaranty, license, agreement or other contract, instrument or contractual obligation to which PTC or any Subsidiary is now a party or by which it or any of its properties or assets may be bound, or (iii) any order, writ, injunction or decree applicable to PTC or any Subsidiary, except for possible Violations that, individually or in the aggregate, do not, and, insofar as reasonably can be foreseen, in the future will not, have a Material Adverse Effect on PTC. (k) COMPLIANCE WITH LICENSES, PERMITS AND APPLICABLE LAWS.

PTC hereby consents to the Contemplated Offering, should IUB determine to commence it. Any decision not to commence the Contemplated Offering by IUB, or any failure to consummate the Contemplated Offering for any reason (other than a material breach by PTC of its obligations under this Section 5.21), shall not affect the obligations of IUB or PTC under this Agreement. With respect to the Contemplated Offering, PTC shall provide IUB and its legal counsel, accountants and other representatives, and to the underwriter of the Contemplated Offering and its legal counsel and other representatives, with such information about the business and condition (financial and otherwise) of PTC as they collectively shall deem necessary or appropriate in connection with the registration and consummation of the Contemplated Offering under the Securities Act and any applicable state securities or blue sky laws. PTC shall instruct and otherwise use its best efforts to cause its directors, officers, employees, agents and advisors to cooperate with IUB and the underwriter of the Contemplated Offering, and the respective representatives and advisors of each, with respect to the provision of such information regarding PTC.

None of the information supplied or to be supplied by PTC for inclusion in the registration statement relating to the Contemplated Offering (and in the prospectus constituting a part thereof) will, at the time the registration statement is filed with the SEC, at the time it becomes effective and at the time of consummation of the Contemplated Offering, contain any untrue statement of a material fact or omit to state any 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. Prior to filing the registration statement relating to the Contemplated Offering (or any amendment or supplement thereto), IUB will take such actions as are reasonable under the circumstances to provide PTC, on a confidential basis, with copies of such registration statement (or amendment or supplement) proposed to be filed with the SEC, and to allow PTC the opportunity to comment promptly thereon with respect to information disclosed about PTC. In the event the Merger is not consummated (other than (i) because of a breach by PTC of any representation, warranty, covenant or other agreement contained in this Agreement which would give rise to the failure of a condition set forth in Section 6.2(a) or 6.2(b) or (ii) the termination of this Agreement by PTC pursuant to Section 7.1(e)), IUB shall reimburse PTC for all its reasonable out-of-pocket expenses actually incurred in connection with the performance of its obligations under this Section 5.21, up to a maximum of $10,000, which amount shall be payable by wire transfer of same day funds within 5 business days of written demand, accompanied by a reasonably detailed statement of such expenses and appropriate supporting documentation therefor. 26 5.22 PTC ALLOWANCE PROVISION.
