AGREEMENT AND PLAN OF MERGER, dated as of May 26, 2005 (this “Agreement”), among Digi International Inc., a Delaware corporation (“Buyer”), Karat Sub Inc., a California corporation formed and wholly owned by Buyer (“Buyer Subsidiary”), and Z-World, Inc., a California corporation (the “Company” and, together with Buyer Subsidiary, sometimes hereinafter referred to as the “Constituent Corporations”). Certain terms used in this Agreement have the meanings given thereto in Section 9.8 hereof.

WHEREAS, the respective Boards of Directors of the Company, Buyer and Buyer Subsidiary have determined that it is advisable and in the best interests of their respective shareholders to consummate, and have approved, the merger of the Buyer Subsidiary with and into the Company (the “Merger”) and the other transactions contemplated by this Agreement; and

WHEREAS, the Company, Buyer and Buyer Subsidiary desire to make certain representations, warranties and agreements in connection with, and to prescribe various conditions to, the Merger.

NOW, THEREFORE, in consideration of the premises and the respective representations, warranties, covenants and agreements set forth in this Agreement, the parties, intending to be legally bound, agree as follows:

ARTICLE I—THE MERGER

The effects and the consequences of the Merger shall be as set forth in Section 1.4.

Section 1.2 Closing. The closing of the Merger (the “Closing”) will take place at 10:00 a.m. (Central Time), on May 26, 2005, or at such other time as is agreed to in writing by the parties (the date of the Closing is referred to as the “Closing Date”). The Closing shall take place at the offices of Faegre & Benson LLP, 90 South Seventh Street, Minneapolis, Minnesota 55402, or at such other location as is agreed to in writing by the parties.

Section 1.3 Effective Time of the Merger. Subject to the provisions of this Agreement, an appropriate officer of each of the Constituent Corporations shall execute and acknowledge a duly prepared agreement of merger and officers’ certificates thereto (together, the “Certificate of Merger”), which shall be filed with the Secretary of State of the State of California in accordance with Section 1103 of the California General Corporation Law (the “CGCL”). The Certificate of Merger shall be filed as soon as practicable on the Closing Date (or such other date as is agreed to in writing by the parties) following the Closing. The Merger shall become effective at the close of business on the Closing Date or at such other legally permissible time as is agreed to by the parties and provided in the Certificate of Merger (the date and time the Merger becomes effective is referred to as the “Effective Time”).

Section 1.4 Effects of the Merger. At the Effective Time:

(a) The Buyer Subsidiary shall be merged with and into the Company, the separate corporate existence of the Buyer Subsidiary shall cease, and the Company shall be the Surviving Corporation;

(b) the Articles of Incorporation and the By-Laws of the Surviving Corporation shall be the Articles of Incorporation and the By-Laws in the form of Exhibit A and Exhibit B hereto; and

Section 1.5 Directors and Officers. The directors of Buyer Subsidiary at the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation, such directors to serve until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Surviving Corporation’s Articles of Incorporation and By-Laws.

ARTICLE II—MERGER CONSIDERATION; CONVERSION OF COMPANY SHARES IN THE MERGER; STOCK OPTIONS

Section 2.1 Merger Consideration; Conversion of Company Shares in Merger. The manner of converting shares of the Company and the Buyer Subsidiary in the Merger shall be as follows:

(a) At the Effective Time, all of the shares of Class A Voting Common Stock of the Company (the “Class A Common Stock”) and Class B Nonvoting Common Stock of the Company (the “Class B Common Stock” and, together with the Class A Common Stock, the “Company Shares”) issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive $49,000,000.00 minus the Option Consideration (as defined in Section 2.2 hereof) (the “Merger Consideration”).

(b) At the Effective Time, (i) all issued and outstanding Company Shares to be converted pursuant to this Section 2.1 shall, by virtue of the Merger and without any action on the part of the holders thereof, cease to be outstanding, be canceled and retired and cease to exist, and each holder of a certificate representing any such Company Shares shall thereafter cease to have any rights with respect to such Company Shares, except the

right to receive for each of the Company Shares, upon the surrender of such certificate in accordance with Section 2.3, Merger Consideration as contemplated by Section 2.3; and (ii) each share of Common Stock, par value $.01 per share, of Buyer Subsidiary issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the same number of shares of Common Stock of the Surviving Corporation.

Section 2.2 Option Consideration. As no outstanding option to purchase Company Shares (each, an “Option” and, collectively, the “Options”) will be assumed by Buyer or Buyer Subsidiary and no substitute options to purchase capital stock of Buyer or Buyer Subsidiary will be granted in connection with the Merger, each vested or unvested Option shall expire at the Effective Time pursuant to the terms of the Company’s 1997 Stock Option Plan, as amended, and become the right to receive an amount in cash, rounded to the nearest whole cent, equal to (i) the difference between $68.40982341 and the per share exercise price of such Option multiplied by the number of Company Shares subject to such Option, less (ii) the amount of any applicable withholding tax obligations with respect to the payment of the amount of such difference. The aggregate amount of consideration payable to the holders of Options pursuant to this Section 2.2 is referred to in this Agreement as the “Option Consideration.”

Section 2.3 Payment for Company Shares and Options in the Merger.

(a) At the Effective Time, Buyer shall deliver to each holder of certificates which immediately prior to the Effective Time represented outstanding Company Shares (the “Certificates”) current funds in that amount which bears the same ratio to the total Merger Consideration as the number of Company Shares represented by the Certificates surrendered by such holder to Buyer for cancellation bears to the total number of Company Shares issued and outstanding immediately prior to the Effective Time. The amounts payable to the various shareholders of the Company upon surrender of their Certificates are set forth on Exhibit C hereto.

(b) At the Effective Time, Buyer shall deliver to each holder of an Option current funds in the amount calculated in accordance with Section 2.2 with respect to each Option. The amounts payable to the various holders of Options in connection with the Merger are set forth on Exhibit C hereto.

Section 2.4 No Transfer of Company Shares. No transfer of Company Shares shall be made on the stock transfer books of the Company after the date hereof.

Section 2.5 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Company Shares that are issued and outstanding immediately prior to the Effective Time and are held by shareholders who have the right (to the extent such right is available by law) to demand and receive payment of the fair value of their Company Shares in the manner provided in Chapter 13 of the CGCL and have not failed to perfect or effectively withdrawn or lost such right under the CGCL, as the case may be, prior to the time provided therefor under the CGCL (“Dissenting Shares”) will not be converted into the right to receive the Merger Consideration; provided, however, that if any holder of Dissenting Shares shall fail to perfect or shall have effectively withdrawn or lost such right, such Company Shares shall thereupon be

deemed to have been converted into and to have become exchangeable for the right to receive the Merger Consideration, without interest. Buyer shall cause the Surviving Corporation to honor its obligations under the CGCL to holders of Dissenting Shares.
