(a) Conversion. At the Effective Time of Merger, by virtue of the Merger and without any action on the part of Acquisition, ZERO, API or the holders of ZERO Common Stock: (i) Each share of ZERO Common Stock issued and outstanding at the Effective Time of Merger shall be converted into 0.85 shares of API Common Stock ("the Exchange Ratio") on the terms and conditions set forth in this Agreement subject to the provisions of Section 2.8(e) of this Agreement concerning cash being paid for fractional shares. 6 (ii) Any shares of ZERO Common Stock that are owned by any of the ZERO Companies at the Effective Time of Merger shall be canceled and retired and cease to exist and no API Common Stock or other consideration shall be issued or delivered in exchange therefor. (b) Adjustment. In the event that, prior to the Effective Time of Merger, there is a reclassification, stock split or stock dividend with respect to outstanding API Common Stock or outstanding ZERO Common Stock, appropriate and proportionate adjustment, if any, shall be made to the Exchange Ratio. 2.7 Conversion of Acquisition Common Stock. At the Effective Time of Merger, and without any action on the part of the holders of common stock of Acquisition, each share of common stock of Acquisition issued and outstanding at the Effective Time of Merger shall be converted into one (1) share of ZERO Common Stock. 2.8 Exchange of ZERO Certificates. (a) Exchange Agent. As of the Effective Time of Merger, API shall deposit, or shall cause to be deposited, with Firstar Trust Company, Milwaukee, Wisconsin, or such other bank or trust company designated by API and approved by ZERO, which approval shall not be unreasonably withheld (the "Exchange Agent"), for the benefit of the holders of shares of ZERO Common Stock, for exchange in accordance with this Article II of this Agreement through the Exchange Agent, certificates representing the shares of API Common Stock (such certificates for shares of API Common Stock, together with any dividends or distributions with respect thereto and together with any cash for fractional share interests made pursuant to Section 2.8(e) of this Agreement, being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.6 of this Agreement in exchange for outstanding shares of ZERO Common Stock. (b) Exchange Procedures. (i) At or promptly after the Effective Time of Merger, API shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time of Merger represented outstanding shares of ZERO Common Stock (the "ZERO Certificates"): (A) a letter of transmittal which shall be in such form and have such provisions as API may reasonably specify; and (B) instructions to effect the surrender of the ZERO Certificates in exchange for certificates representing shares of API Common Stock. (ii) Upon surrender of a ZERO Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed, and with such other documents as the Exchange Agent may reasonably require, the holder of such ZERO Certificate shall be entitled to receive, and API shall cause the Exchange Agent to promptly deliver in exchange therefor, a certificate representing that number of whole shares of API Common Stock to which such holder is entitled in respect of such ZERO Certificate pursuant to the provisions of this Article II of this Agreement, plus any cash in lieu of any fractional share interest in 7 accordance with Section 2.8(e) of this Agreement, and the ZERO Certificate so surrendered shall forthwith be canceled; provided, however, that fractional share interests of any one holder shall be aggregated to maximize the number of whole shares of API Common Stock to be issued and minimize the fractional interests to be paid in cash as provided in Section 2.8(e) of this Agreement. (iii) In the event of a transfer of ownership of shares of ZERO Common Stock which is not registered in the transfer records of ZERO, a certificate representing the proper number of shares of API Common Stock, and any cash in lieu of any fractional share interests in accordance with Section 2.8(e) of this Agreement, shall be delivered to the transferee if the ZERO Certificate which represented such shares of ZERO Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. (iv) Until surrendered as contemplated by this Section 2.8 of this Agreement, each ZERO Certificate shall be deemed at all times after the Effective Time of Merger to represent only the right to receive upon surrender a certificate representing shares of API Common Stock and cash in lieu of any fractional share interest as contemplated by Section 2.8(e) of this Agreement. (c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time of Merger with respect to API Common Stock with a record date after the Effective Time of Merger shall be paid to the holder of any unsurrendered ZERO Certificate with respect to the shares of API Common Stock represented thereby, and no cash payment in lieu of a fractional share shall be paid to any such holder pursuant to Section 2.8(e) of this Agreement, until the holder of such ZERO Certificate has surrendered such ZERO Certificate to the Exchange Agent. Subject to the effect of any applicable Law, following the surrender of any such ZERO Certificate, there shall be paid to the holder of the certificate representing whole shares of API Common Stock issued in exchange for the surrendered ZERO Certificates, without interest: (i) promptly, the amount of any cash payable with respect to a fractional share interest to which such holder is entitled pursuant to Section 2.8(e) of this Agreement and the amount of dividends or other distributions with a record date after the Effective Time of Merger theretofore paid with respect to such whole shares of API Common Stock; and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time of Merger but prior to surrender and a payment date occurring after surrender payable with respect to such whole shares of API Common Stock. (d) No Further Rights in ZERO Common Stock. All shares of API Common Stock issued upon conversion of the ZERO Common Stock in accordance with the terms of this Agreement (and any cash paid pursuant to Section 2.8(e) of this Agreement) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the ZERO Common Stock. 8 (e) No Fractional Shares. No fractional shares of API Common Stock shall be issued in the Merger. All fractional share interests of a holder of more than one ZERO Certificate at the Effective Time of Merger shall be aggregated. If a fractional share interest results after such aggregation, each holder of a fractional share interest shall be paid an amount in cash equal to the product obtained by multiplying such fractional share interest by the average of the closing price per share of API Common Stock as reported on the New York Stock Exchange - Composite Transactions on each of the ten (10) consecutive trading days ending on and including the fifth (5th) trading day immediately preceding the Closing Date. Promptly after the determination of the amount of cash, if any, to be paid to holders of fractional share interests, the Exchange Agent shall notify API and API shall deliver such amounts to such holders subject to and in accordance with the terms of Section 2.8(c) of this Agreement. (f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the ZERO Stockholders after twelve (12) months after the Effective Time of Merger shall be delivered to API, upon demand, and any ZERO Stockholders who have not theretofore complied with this Article II of this Agreement shall thereafter look only to API for payment of their claim for shares of API Common Stock, any cash in lieu of fractional share interests and any dividends or distributions with respect to API Common Stock. (g) No Liability. Neither the Exchange Agent nor any party to this Agreement shall be liable to any ZERO Stockholder for any shares of ZERO Common Stock or API Common Stock (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law. (h) Withholding Rights. API shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any ZERO Stockholder such amounts as API is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax Law. To the extent that amounts are so withheld by API, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the ZERO Stockholder in respect of which such deduction and withholding was made by API. (i) Book Entry. Notwithstanding any other provision of this Agreement, the letter of transmittal referred to in Section 2.8(b) of this Agreement may, at the option of API, provide for the ability of a holder of one or more ZERO Certificates to elect that API Common Stock to be received in exchange for the ZERO Common Stock formerly represented by such surrendered ZERO Certificates be issued in uncertificated form. 2.9 Stock Transfer Books. At the Effective Time of Merger, the stock transfer books of ZERO shall be closed and there shall be no further registration of transfers of shares of ZERO Common Stock thereafter on the records of ZERO. From and after the Effective Time of Merger, the holders of ZERO Certificates outstanding immediately prior to the Effective Time of Merger shall cease to have any rights with respect to such shares of ZERO Common Stock except as otherwise provided in this Agreement or by Law. 9 2.10 Reorganization; Pooling. The parties intend that this Agreement be a plan of reorganization within the meaning of Section 368(a) of the Code and that the Merger be a tax-free reorganization under Section 368(a) of the Code and that the Merger qualify for pooling of interests accounting treatment. 2.11 No Dissenting Shares. The parties acknowledge that under the DGCL, the ZERO Stockholders are not entitled to dissent from the Merger and are not entitled to require appraisal of their ZERO Common Stock. 2.12 ZERO Stock Options. (a) Conversion. At the Effective Time of Merger, each outstanding option to purchase shares of ZERO Common Stock (a "ZERO Option") under ZERO's 1994 Stock Option Plan or ZERO's 1988 Stock Option Plan, each as amended (the "ZERO Option Plans"), whether vested or unvested, shall be deemed to constitute an option to acquire, on the same terms and conditions as were applicable under such ZERO Option, the same number of shares of API Common Stock as the holder of such ZERO Option would have been entitled to receive pursuant to the Merger had such holder exercised such option in full immediately prior to the Effective Time of Merger (rounded down to the nearest whole number), at a price per share (rounded up to the nearest whole cent) equal to: (i) the aggregate exercise price for the shares of ZERO Common Stock otherwise purchasable pursuant to such ZERO Option; divided by (ii) the number of full shares of API Common Stock deemed purchasable pursuant to such ZERO Option in accordance with the foregoing; provided, however, that in the case of any ZERO Option which is intended to be an "incentive stock option" (as defined in Section 422 of the Code), the option price, the number of shares purchasable pursuant to such option and the terms and conditions of exercise of such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code. At or prior to the Effective Time of Merger, ZERO shall make all necessary arrangements to permit the assumption of the unexercised ZERO Options by API pursuant to this Section. (b) Assumption. Effective at the Effective Time of Merger, API shall assume each ZERO Option in accordance with the terms of the ZERO Option Plan under which it was issued and all of the terms and conditions of the stock option agreement by which it is evidenced. At or prior to the Effective Time of Merger, API shall take all corporate action necessary to reserve for issuance a sufficient number of shares of API Common Stock for delivery upon exercise of ZERO Options assumed by it in accordance with this Section 2.12 of this Agreement. As soon as practicable after the Effective Time of Merger, API shall file a registration statement (or a post-effective amendment to the Registration Statement) on Form S-8 (or any successor or other appropriate form) with respect to the API Common Stock subject to such ZERO Options, and shall use its best efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses relating thereto) for so long as such ZERO Options remain outstanding. 10 ARTICLE III OTHER AGREEMENTS 3.1 Joint Proxy Statement and Registration Statement. API and ZERO will prepare and file with the SEC the Registration Statement and the Proxy Statement as soon as reasonably practicable after the date of this Agreement. API and ZERO shall use reasonable best efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as practicable after such filing. API and ZERO shall also take such action as may be reasonably required to cause the shares of API Common Stock issuable pursuant to the Merger to be registered or to obtain an exemption from registration or qualification under applicable state "blue sky" or securities Laws; provided, however, that API shall not be required to qualify as a foreign corporation or to file any general consent to service of process under the Laws of any jurisdiction or to comply with any other requirements deemed by API to be unduly burdensome. Each party to this Agreement will furnish to the other parties all information concerning itself as each such other party or its counsel may reasonably request and which is required or customary for inclusion in the Proxy Statement and the Registration Statement. 3.2 Approval of Stockholders. (a) ZERO Stockholders.

Very truly yours, ----------------------------------------- [Name] Dated: ----------------------- EXHIBIT 1B TO MERGER AGREEMENT FORM OF ZERO AFFILIATE LETTER Gentlemen: The undersigned is a holder of shares of Common Stock, par value $.01 per share ("ZERO Common Stock") of ZERO Corporation, a Delaware corporation ("ZERO") and is entitled to receive shares of Class A Common Stock, par value $.20 per share, (the "Shares") of Applied Power Inc., a Wisconsin corporation ("API") in connection with the merger (the "Merger") of ZERO with a subsidiary of API pursuant to an Agreement and Plan of Merger by and among ZERO, API and a subsidiary of API dated as of April 6, 1998. The undersigned acknowledges that the undersigned may be deemed an "affiliate" of ZERO within the meaning of Rule 145 ("Rule 145") promulgated under the Securities Act of 1933, as amended (the "Act"), and/or as such term is used in and for purposes of Accounting Series Releases 130 and 135, as amended, of the Securities and Exchange Commission (the "Commission"), although nothing contained herein shall be construed as an admission of such status. If in fact the undersigned were an affiliate of ZERO under the Act, the undersigned's ability to sell, assign or transfer any Shares received by the undersigned in exchange for any shares of ZERO Common Stock pursuant to the Merger may be restricted unless such transaction is registered under the Act or an exemption from such registration is available. The undersigned understands that such exemptions are limited and the undersigned has obtained advice of counsel as to the nature and conditions of such exemptions, including information with respect to the applicability to the sale of such securities of Rules 144 and 145(d) promulgated under the Act. The undersigned hereby represents to and covenants with ZERO that it will not sell, assign or transfer any Shares received by the undersigned in exchange for shares of ZERO Common Stock pursuant to the Merger except (i) pursuant to an effective registration statement under the Act, (ii) by a sale made in conformity with the volume and other limitations of Rule 145 (and otherwise in accordance with Rule 144 under the Act if the undersigned is an affiliate of API and if so required at the time) or (iii) in a transaction which, in the opinion of independent counsel reasonably satisfactory to API or as described in a "no- action" or interpretive letter from the Staff of the Commission, is not required to be registered under the Act. The undersigned understands that API is under no obligation to register the sale, transfer or other disposition of the Shares by the undersigned or on behalf of the undersigned under the Act or to take any other action necessary in order to make compliance with an exemption from such registration available solely as a result of the Merger. In the event of a sale of Shares received by the undersigned in the Merger pursuant to Rule 145, the undersigned will supply API with evidence of compliance with such Rule, in the form of customary seller's and broker's Rule 145 representation letters or as API may otherwise reasonably request. The undersigned understands that API may instruct its transfer agent to withhold the transfer of any Shares disposed of by the undersigned in a manner inconsistent with this letter. The undersigned acknowledges and agrees that appropriate legends will be placed on certificates representing Shares received by the undersigned in the Merger or held by a transferee thereof, which legends will be removed (i) by delivery of substitute certificates upon receipt of an opinion in form and substance reasonably satisfactory to API to the effect that such legends are no longer required for the purposes of the Act and the rules and regulations of the Commission promulgated thereunder or (ii) in the event of a sale of the Shares which has been registered under the Act or made in conformity with the provisions of Rule 145. The undersigned further represents to, and covenants with API that the undersigned will not, during the 30 days prior to the effective time of the Merger sell, transfer or otherwise dispose of, or reduce any risk relative to, any securities of API or ZERO, and the undersigned will not sell, transfer or otherwise dispose of, or reduce any risk relative to, the Shares received by the undersigned in the Merger or any other shares of the capital stock of API until after such time as results covering at least 30 days of operations of API (including the combined operations of ZERO and API) have been published by API in the form of a quarterly earnings report, an effective registration statement filed with the Commission, a report to the Commission on Form 10-K, 10-Q, or 8- K, or any other public filing or announcement which includes such results of operations. 2 The undersigned has carefully reviewed this letter and understands the requirements hereof and the limitations imposed upon the distribution, sale, transfer or other disposition of securities of API and ZERO. Very truly yours, ----------------------------------------- [Name] Dated: As an inducement to the above individual to deliver this letter, API agrees that for so long as and to the extent necessary to permit such individual to sell the Shares pursuant to Rule 145 and, to the extent applicable, Rule 144 under the Act, API shall use all reasonable efforts to file, on a timely basis, all reports and data required to be filed by it with the Commission pursuant to Section 13 of the Securities Exchange Act of 1934.
