PART I

ITEM 1.   BUSINESS
          Digi International Inc. ("Digi" or the "Company") was formed in l985
          as a Minnesota corporation and reorganized as a Delaware corporation
          in l989.  The Company is a worldwide provider of data communications
          products for open systems, server-based remote access, and local area
          network ("LAN") applications. Digi's communications products, which
          support a broad range of server platforms and network operating
          systems in the industry, enable people to have access to information,
          no matter when they need it, or what type of computer they are using.

          Digi's products enhance the development of open systems, server-based
          communication by being compatible with all PC platforms - Compaq, IBM,
          Hewlett-Packard, and Sun Microsystems - and popular operating systems,
          including Microsoft Windows NT and Novell NetWare.  Digi's solutions
          give customers the flexibility to scale up easily as needs change and
          to choose from a variety of industry-standard, cost effective
          alternatives.  Digi's products also support remote access connectivity
          through intranets and the Internet.

          The Company's server-based communications serial port boards provide
          asynchronous (transmitting single characters at a time) and
          synchronous (transmitting characters in a group) data transmissions
          for analog modems, ISDN (Integrated Services Digital Network), X.25,
          Frame Relay or T1/E1 connections.

          The Company's serial port communications products constituted
          approximately 80%, 76% and 80% of net sales in fiscal 1998, 1997 and
          1996, respectively.  These products provide connections for two
          primary markets:

          1.   The core serial port products provide PC-host-to-terminal serial
               I/O (input/output) connections. These products facilitate data
               transmission for point-of-sale ("POS") applications, on-line
               transaction processing, factory automation, inventory control and
               office automation, among others. The onboard firmware allows the
               products to quickly, accurately and reliably transmit data,
               thereby eliminating the information bottlenecks that can result
               when multiple users or devices share one processing unit. These
               solutions primarily use multiuser, multitasking operating systems
               such as UNIX (and its variations), along with standard PC servers
               and communications cards.

          2.   Open systems, server-based remote access products are data
               communications boards that support remote access applications
               such as Internet access, connectivity to corporate intranets and
               branch office networks, and telecommuting.

          The Company entered the LAN market with its acquisition of MiLAN
          Technology Corporation in November 1993. The Company's LAN business,
          formerly the MiLAN Technology Division, provides cost-effective and
          power-efficient Ethernet, Fast Ethernet and Token Ring networking
          connectivity products that are installed on a LAN to increase its
          productivity.


                                          4
<PAGE>

          The Company's LAN connectivity products include these two groups:

          1.   The physical layer products allow users to easily build and
               expand networks using a variety of technologies including
               Ethernet, Fast Ethernet, Gigabit Ethernet and ATM. These products
               include single and multiport transceivers, converters, microhubs
               and  modular repeaters.

          2.   The print server products, based on the FastPort line, make print
               sharing convenient and affordable.  The FastPort line includes
               the industry's first multiprotocol network print server providing
               access to any printer on an Ethernet or Token Ring network
               without the inconvenience and expense of spooling through a
               workstation or server.

          The Company entered the Internet telephony market with the acquisition
          of  ITK International, Inc. ("ITK International") in July of 1998 and
          its Voice over Internet Protocol ("VoIP") technology.  ITK
          International provides the new VoIP technology with the NetBlazer 8500
          gateway, a "proof of concept" product that converts voice signals to
          TCP/IP packets and routes them over IP networks such as the Internet
          and company intranets.  This capability combines voice and data onto
          one cost-effective network and is changing the whole concept of
          traditional voice communication.  Although the VoIP technology
          acquired from ITK International is still under development, the
          Company believes that this technology will be successful once a
          functioning, finished product is complete.  Digi acquired ITK
          International for approximately $27.7 million in cash, stock,
          replacement stock options and the assumption of $39.8 million of
          liabilities and restructuring/integration costs.

          The Company expanded its product lines with its acquisition of Central
          Data Corporation ("Central Data") in July 1998.  The Company also
          acquired in-process research and development from Central Data related
          to Universal Serial Bus (USB) technology.  This in-process technology
          will give customers the ability to maintain existing non-USB
          peripheral equipment and connect with new PCs which contain advanced
          USB interfaces.  The Company expects to introduce USB products in
          fiscal 1999.  Digi acquired Central Data for approximately $19.2
          million in cash, stock, replacement stock options and the assumption
          of $4.4 million of liabilities and restructuring/integration costs.

          The Company works closely with customers, PC and server vendors,
          operating system companies and other marketing partners to
          continuously optimize Digi's wide area network ("WAN") and LAN
          products to interoperate in open systems, industry-standard
          environments. This assures customers the ability to choose the most
          flexible, cost-effective solution to meet their individual needs.

          The Company markets its products to a broad range of customers,
          including major domestic and international distributors, end users,
          system integrators, VARs and OEMs.  This network includes more than
          185 distributors in the United States, Canada and 65 countries
          worldwide, as well as OEM customers.

          In July 1991, the Company opened a sales support office in Germany to
          increase sales support to the European distribution network.  The
          Company expanded its presence in the


                                          5
<PAGE>

          German market in July 1998 with the acquisition of ITK International,
          which maintains a sales and manufacturing office in Dortmund, Germany.
          In October 1993, the Company opened a sales support office in
          Singapore to increase sales support for its products to the Pacific
          Rim distribution network.  In 1996, the Company opened similar offices
          in Hong Kong, Sydney and Tokyo and in 1997, the Company opened sales
          offices in Paris and London to better serve its non-U.S. markets.

          To serve its worldwide markets, the Company (i) offers products that,
          in the opinion of management, provide superior performance relative to
          current standards and application requirements, (ii) provides products
          that are compatible with a broad array of open systems operating
          systems and industry-standard PC, server and workstation
          architectures, and (iii) provides, in the opinion of management,
          superior technical support, including frequent and timely product
          updates and ready access to the Company's support staff.

          The computer industry is characterized by rapid technological advances
          and evolving industry standards. The market can be significantly
          affected by new product introductions and marketing activities of
          industry participants. The Company competes for customers on the basis
          of product performance in relation to compatibility, support, quality
          and reliability, product development capabilities, price and
          availability. Many of the Company's competitors and potential
          competitors have greater financial, technological, manufacturing,
          marketing and personnel resources than the Company. The Company
          believes that it is the market leader in serial port boards for
          server-based communications in the computer industry.  With respect to
          the LAN business, the Company believes it commands less than a 5%
          market share.  The Company is currently establishing its position in
          the remote access market for the Company's RAS product lines.  The
          Company will enter the Internet telephony market upon full development
          of its VoIP technology.

          The Company's manufacturing operations procure all parts and certain
          services involved in the production of products. The Company
          subcontracts most of its product manufacturing to outside firms that
          specialize in providing such services.  The Company believes that this
          approach to manufacturing is beneficial because it permits the Company
          to reduce its fixed costs, maintain production flexibility and
          maximize its profit margins.

          The Company's products are manufactured to its designs with 
          standard and semi-custom components.  Most of these components are 
          available from multiple vendors.  The Company does have several 
          single-sourced supplier relationships, either because alternative 
          sources are not available or because the relationship is 
          advantageous to the Company.  If these suppliers are unable to 
          provide timely and reliable supply of components, the Company could 
          experience manufacturing delays adversely affecting its results of 
          operations.  

          During fiscal years 1996, 1997 and 1998, the Company's research and
          development  expenditures were $21.3, $18.0, and $17.0 million,
          respectively.

          Due to rapidly changing technology in the computer industry, the
          Company believes that its success depends primarily upon the
          engineering, marketing, manufacturing and support skills of its
          personnel, rather than upon patent protection.  Although the Company
          may seek patents where appropriate and has certain patent applications
          pending for proprietary technology, the Company's proprietary
          technology or products are generally not patented.  The Company relies
          primarily on the copyright, trademark and trade secret laws to protect
          its proprietary rights in its products.  The Company has established
          common law and registered trademark rights on a family of marks for a
          number of its products.


                                          6

          In May 1998, the Company exchanged its previously purchased
          $13,796,525 of convertible notes from AetherWorks Corporation, a
          development stage company engaged in the development of wireless and
          dial-up remote access technology, for a non-interest bearing
          $8,000,000 non-convertible note.  As a part of the exchange, the
          Company relinquished its rights to any future technology or claims on
          any of AetherWorks' intellectual properties.  In exchange, the Company
          has been released from all of its guarantees of certain lease
          obligations of AetherWorks.  As a result, the Company has reversed its
          $1,350,000 accruals established in the fourth quarter of 1997, for the
          estimated probable cost related to its guarantee of such lease
          obligations and has included such amount as AetherWorks Corporation
          gain for the year ended September 30, 1998.

          Due to the significant uncertainty as to collectibility of the
          $8,000,000 note, which matures in 2001, the note has been recorded
          with no carrying value as of September 30, 1998.  The Company
          continues to lease to AetherWorks $1,325,000 of computer equipment
          under a three-year direct financing lease, expiring in 2000.

          During the year ended September 30, 1998, two customers comprised more
          than 10% of net sales each: Ingram Micro at 15.5% and Tech Data at
          13.7% . During the year ended September 30, 1997, two customers
          comprised more than 10% of net sales each: Ingram Micro at 15.1%, and
          Tech Data at 10.5%.  During the year ended September 30, 1996, two
          customers accounted for more than 10% of net sales each: Tech Data at
          13.9% and Ingram Micro at 13.4%.

          As of September 30, 1998, the Company had backlog orders which
          management believed to be firm in the amount of $2.9 million. All of
          these orders are expected to be filled in the current fiscal year.
          Backlog as of September 30, 1997 was $14.7 million.

          Total employees at September 30, 1998 were 703.

ITEM 2.   PROPERTIES

          The Company's headquarters and research facilities are located in a
          130,000 square foot office building in Minnetonka, Minnesota which the
          Company acquired in August 1995 and has occupied since March 1996.
          The Company's primary manufacturing facility is currently located in a
          58,000 square foot building in Eden Prairie, Minnesota, which the
          Company purchased in May 1993 and has occupied since August 1993.
          Additional office and research facilities include a 46,170 square foot
          facility in Sunnyvale, California, the lease for which expires in

          International are located in a 63,000 square foot facility in
          Dortmund, Germany.  The headquarters and research facility owned by
          Central Data are located in a 20,000 square foot facility located in
          Champaign, Illinois.

          adequate for current office, research and warehouse requirements, and
          that its manufacturing facilities provide sufficient production
          capacity to meet the Company's currently anticipated needs.

ITEM 3.   LEGAL PROCEEDINGS

          Between January 3, 1997 and March 7, 1997, the Company and certain of
          its previous officers were named as defendants in five putative
          securities class action lawsuits filed in the United States District
          Court for the District of Minnesota on behalf of an alleged class of
          purchasers for its common stock during the period January 25, 1996,
          through December 23, 1996.  The five putative class actions were
          thereafter consolidated, and on May 12, 1997, a consolidated amended
          class action complaint (the "Consolidated Amended Complaint") was
          filed in the actions, which are captioned IN RE DIGI INTERNATIONAL
          INC. SECURITIES LITIGATION (Master File No. 97-5 DWF/RLE).  The
          Consolidated Amended Complaint alleges that the Company and its
          previous officers Ervin F. Kamm, Jr., Gerald A. Wall and Gary L.
          Deaner violated the federal securities laws by, among other things,
          misrepresenting and/or omitting material information concerning the
          Company's operations and financial results.  The Consolidated Amended
          Complaint seeks compensatory damages in an unspecified amount plus
          interest against all defendants, jointly and severally, and an award
          of attorneys' fees, experts' fees and costs.

          On February 25, 1997, the Company and certain of its previous officers
          also were named as defendants in a securities lawsuit filed in the
          United States District Court for the District of Minnesota by the
          Louisiana State Employees Retirement System, which is captioned
          LOUISIANA STATE EMPLOYEES RETIREMENT SYSTEM V. DIGI INTERNATIONAL
          INC., GARY L. DEANER, ERVIN F. KAMM, JR., GERALD A. WALL AND "JOHN
          DOE" AND "RICHARD ROE", DEFENDANTS (Civil File No. 97-440, Master File
          No. 97-5 DWF/RLE).  On June 3, 1997, the Louisiana State Employees
          Retirement System filed an Amended Complaint (the "Louisiana Amended
          Complaint").  The Louisiana Amended Complaint alleges that the Company
          and its previous officers Ervin F. Kamm, Jr., Gerald A. Wall and Gary
          L. Deaner violated federal securities laws and state common law by,
          among other things, misrepresenting and/or omitting material
          information concerning the Company's operations and financial results.
          The Louisiana Amended Complaint seeks compensatory damages in the
          amount of $718,404.70 plus interest against all defendants, jointly
          and severally, and an award of attorneys' fees, disbursements and
          costs.

          In a decision issued on May 22, 1998, the United States District Court
          for the District of Minnesota granted in part and denied in part
          defendants' motions to dismiss the Consolidated Amended Complaint and
          the Louisiana Amended Complaint.  The Court dismissed without leave to
          replead all claims asserted in both cases, except for certain federal
          securities law claims based upon alleged misrepresentation and/or
          omissions relating to the accounting treatment applied to the
          Company's AetherWorks investment.  The Court also limited the claims
          asserted in the Louisiana Amended Complaint to the


                                          8
<PAGE>

          11,000 shares of the Company's stock held subsequent to November 14,
          1996, for which the Louisiana Amended Complaint claims damages of
          $184,276.40.  The claims in the two actions remain pending against the
          Company and its former officers Ervin F. Kamm, Jr. and Gerald A. Wall.
          Discovery in the actions is proceeding.

          Because the lawsuits are in preliminary stages, the ultimate outcomes
          cannot be determined at this time, and no potential assessment of
          their effect, if any, on the Company's financial position, liquidity
          or future operations can be made.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

          There were no matters submitted to a vote of security holders during
          the quarter ended September 30, 1998.

                          Report of Independent Auditors


Board of Directors and Shareholders
AetherWorks Corporation

We have audited the balance sheets of AetherWorks Corporation (a development 
stage company) as of September 30, 1997 and 1996, and the related statements 
of operations, shareholders' equity (deficit) and cash flows for the years 
then ended and the period from February 24, 1993 (inception) to September 30, 
1997. These financial statements, not separately presented herein, are the 
responsibility of the Company's management. Our responsibility is to express 
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of AetherWorks Corporation (a
development stage company) at September 30, 1997 and 1996, and the results of
its operations and its cash flows for the years then ended and the period from
February 24, 1993 (inception) to September 30, 1997, in conformity with
generally accepted accounting principles.

The financial statements referred to above have been prepared assuming the 
Company will continue as a going concern. As discussed in Note 10 to the 
financial statements, the Company's deficit accumulated during the 
development stage raises substantial doubt about its ability to continue as a 
going concern. The Company intends to obtain additional financing to permit 
it to continue its operations. The financial statements do not include any 
adjustments that might result from the outcome of this uncertainty.

                              DIGI INTERNATIONAL INC.


                                 STOCK OPTION PLAN
                              AS AMENDED AND RESTATED
                                AS OF JULY 28, 1998

1.  PURPOSE OF PLAN.  The purpose of this Digi International Inc. Stock Option
Plan (the "Plan"), is to promote the interests of Digi International Inc., a
Delaware corporation (the "Company"), and its stockholders by providing key
personnel of the Company and its subsidiaries with an opportunity to acquire a
proprietary interest in the Company and thereby develop a stronger incentive to
put forth maximum effort for the continued success and growth of the Company and
its subsidiaries. In addition, the opportunity to acquire a proprietary interest
in the Company will aid in attracting and retaining key personnel of outstanding
ability.

2.  ADMINISTRATION OF PLAN.  This Plan shall be administered by a committee of
two or more directors (the "Committee") appointed by the Company's board of
directors (the "Board"). No person shall serve as a member of the Committee
unless such person shall be a "Non-Employee Director" as that term is defined in
Rule 16b-3(a)(3)(i), promulgated under the Securities Exchange Act of 1934, as
amended (the "Act"), or any successor statute or regulation comprehending the
same subject matter. A majority of the members of the Committee shall constitute
a quorum for any meeting of the Committee, and the acts of a majority of the
members present at any meeting at which a quorum is present or the acts
unanimously approved in writing by all members of the Committee shall be the
acts of the Committee.  Subject to the provisions of this Plan, the Committee
may from time to time adopt such rules for the administration of this Plan as it
deems appropriate. The decision of the Committee on any matter affecting this
Plan or the rights and obligations arising under this Plan or any option granted
hereunder, shall be final, conclusive and binding upon all persons, including
without limitation the Company, stockholders, employees and optionees.  To the
full extent permitted by law, (i) no member of the Committee or the CEO Stock
Option Committee (as defined in this paragraph 2) shall be liable for any action
or determination taken or made in good faith with respect to this Plan or any
option granted hereunder and (ii) the members of the Committee and the CEO Stock
Option Committee shall be entitled to indemnification by the Company against and
from any loss incurred by such member or person by reason of any such actions
and determinations.  The Committee may delegate all or any part of its authority
under this Plan to a one person committee consisting of the Chief Executive
Officer of the Company as its sole member (the "CEO Stock Option Committee") for
purposes of granting and administering awards granted to persons other than
persons who are then subject to the reporting requirements of Section 16 of the
Exchange Act ("Section 16 Individuals").

3.  SHARES SUBJECT TO PLAN.  The shares that may be made subject to options
granted under this Plan shall be authorized and unissued shares of common stock
(the "Common Shares") of the Company, $.01 par value, or Common Shares held in
treasury, and they shall not exceed 4,129,400 in the aggregate, except that, if
any option lapses or terminates for any reason before such option has been
completely exercised, the Common Shares covered by the unexercised portion of
such

<PAGE>

option may again be made subject to options granted under this Plan. Appropriate
adjustments in the number of shares and in the purchase price per share may be
made by the Committee in its sole discretion to give effect to adjustments made
in the number of outstanding Common Shares of the Company through a merger,
consolidation, recapitalization, reclassification, combination, stock dividend,
stock split or other relevant change, provided that fractional shares shall be
rounded to the nearest whole share.

4.  ELIGIBLE PARTICIPANTS.  Options may be granted under this Plan to any key
employee of the Company or any subsidiary thereof, including any such employee
who is also an officer or director of the Company or any subsidiary thereof.
Nonstatutory stock options, as defined in paragraph 5(a) hereof, also shall be
granted to directors of the Company who are not employees of the Company or any
subsidiary thereof (the "Outside Directors") in accordance with paragraph 6
hereof and may also be granted to other individuals or entities who are not
"employees" but who provide services to the Company or a parent or subsidiary
thereof in the capacity of an Outside Director, advisor or consultant.
References herein to "employed," "employment" and similar terms (except
"employee") shall include the providing of services in any such capacity or as a
director.  The employees and other individuals and entities to whom options may
be granted pursuant to this paragraph 4 are referred to herein as "Eligible
Participants."

5.  TERMS AND CONDITIONS OF EMPLOYEE OPTIONS.

          (a)  Subject to the terms and conditions of this Plan, the Committee
     may, from time to time prior to December 1, 2006, grant to such Eligible
     Participants as the Committee may determine options to purchase such number
     of Common Shares of the Company on such terms and conditions as the
     Committee may determine; provided, however, that no Eligible Participant
     may be granted options with respect to more than 250,000 Common Shares
     during any calendar year. In determining the Eligible Participants to whom
     options shall be granted and the number of Common Shares to be covered by
     each option, the Committee may take into account the nature of the services
     rendered by the respective Eligible Participants, their present and
     potential contributions to the success of the Company, and such other
     factors as the Committee in its sole discretion shall deem relevant. The
     date and time of approval by the Committee of the granting of an option
     shall be considered the date and the time of the grant of such option. The
     Committee in its sole discretion may designate whether an option granted to
     an employee is to be considered an "incentive stock option" (as that term
     is defined in Section 422 of the Internal Revenue Code of 1986, as amended,
     or any amendment thereto (the "Code")) or a nonstatutory stock option (an
     option granted under this Plan that is not intended to be an "incentive
     stock option"). The Committee may grant both incentive stock options and
     nonstatutory stock options to the same employee. However, if an incentive
     stock option and a nonstatutory stock option are awarded simultaneously,
     such options shall be deemed to have been awarded in separate grants, shall
     be clearly identified, and in no event shall the exercise of one such
     option affect the right to exercise the other. To the extent that the
     aggregate Fair Market Value (as defined in paragraph 5(c)) of Common Shares
     with respect to which incentive stock options (determined without regard to
     this sentence) are exercisable for the first time by any individual during
     any calendar year (under all plans of the Company and its parent and
     subsidiary corporations) exceeds $100,000, such options shall be treated as
     nonstatutory stock options.

<PAGE>

          (b)  The purchase price of each Common Share subject to an option
     granted pursuant to this paragraph 5 shall be fixed by the Committee. For
     nonstatutory stock options, such purchase price may be set at not less than
     50% of the Fair Market Value (as defined below) of a Common Share on the
     date of grant. For incentive stock options, such purchase price shall be no
     less than 100% of the Fair Market Value of a Common Share on the date of
     grant, provided that if such incentive stock option is granted to an
     employee who owns, or is deemed under Section 424(d) of the Code to own, at
     the time such option is granted, stock of the Company (or of any parent or
     subsidiary of the Company) possessing more than 10% of the total combined
     voting power of all classes of stock therein (a "10% Stockholder"), such
     purchase price shall be no less than 110% of the Fair Market Value of a
     Common Share on the date of grant.

          (c)  For purposes of this Plan, the "Fair Market Value" of a Common
     Share at a specified date shall, unless otherwise expressly provided in
     this Plan, mean the closing sale price of a Common Share on the date
     immediately preceding such date or, if no sale of such shares shall have
     occurred on that date, on the next preceding day on which a sale of such
     shares occurred, on the Composite Tape for New York Stock Exchange listed
     shares or, if such shares are not quoted on the Composite Tape for New York
     Stock Exchange listed shares, on the principal United States securities
     exchange registered under the Act, on which the shares are listed, or, if
     such shares are not listed on any such exchange, on the Nasdaq Stock Market
     or any similar system then in use or, if such shares are not included on
     the Nasdaq Stock Market or any similar system then in use, the mean between
     the closing "bid" and the closing "asked" quotation of such a share on the
     date immediately preceding the date as of which such Fair Market Value is
     being determined, or, if no closing bid or asked quotation is made on that
     date, on the next preceding day on which a quotation is made, on an NASD
     System or any similar system then in use, provided that if the shares in
     question are not quoted on any such system, Fair Market Value shall be what
     the Committee determines in good faith to be 100% of the fair market value
     of such a share as of the date in question. Notwithstanding anything stated
     in this paragraph, if the applicable securities exchange or system has
     closed for the day by the time the determination is being made, all
     references in this paragraph to the date immediately preceding the date in
     question shall be deemed to be references to the date in question.

          (d)  Each option agreement provided for in paragraph 14 hereof shall
     specify when each option granted under this Plan shall become exercisable.

          (e)  Each option granted pursuant to this paragraph 5 and all rights
     to purchase shares thereunder shall cease on the earliest of:

               (i)  ten years after the date such option is granted (or in the
          case of an incentive stock option granted to a 10% Stockholder, five
          years after the date such option is granted) or on such date prior
          thereto as may be fixed by the Committee on or before the date such
          option is granted;

              (ii)  the expiration of the period after the termination of the
          optionee's employment within which the option is exercisable as
          specified in paragraph 8(b) or 8(c), whichever is applicable; or

<PAGE>

             (iii)  the date, if any, fixed for cancellation pursuant to
          paragraph 9 of this Plan.

In no event shall any option be exercisable at any time after its original
expiration date. When an option is no longer exercisable, it shall be deemed to
have lapsed or terminated and will no longer be outstanding.

6.  TERMS AND CONDITIONS OF OUTSIDE DIRECTOR OPTIONS.

          (a)  Subject to the terms and conditions of this Plan, the Committee
     shall grant options to each Outside Director who is not on the date such
     option would be granted the beneficial owner (as defined in Rule 13d-3
     under the Act) of more than 5% of the outstanding Common Shares, on the
     terms and conditions set forth in this paragraph 6. During the term of this
     Plan and provided that sufficient Common Shares are available pursuant to
     paragraph 3:

               (i)  each person who is elected to be an Outside Director and who
          was not at any time previously a director of the Company shall be
          granted a nonstatutory stock option. The date such person is elected
          to be an Outside Director of the Company shall be the date of grant
          for such options granted pursuant to this subparagraph 6(a)(i). The
          number of Common Shares covered by each such option shall be 5,000;

              (ii)  each person who is an Outside Director at the conclusion of
          an Annual Meeting of Stockholders shall be granted a nonstatutory
          stock option on the date of such Annual Meeting of Stockholders. The
          date of such Annual Meeting of Stockholders shall also be the date of
          grant for options granted pursuant to this subparagraph 6(a)(ii). The
          number of Common Shares covered by each such option shall be 1,500;

             (iii)  each person who is elected to be an Outside Director between
          Annual Meetings of Stockholders shall be granted a nonstatutory stock
          option. The date such person is elected to be an Outside Director of
          the Company by the Board shall be the date of grant for such options
          granted pursuant to this subparagraph 6(a)(iii). The number of Common
          Shares covered by each such option shall be 1,500 multiplied by a
          fraction, the numerator of which shall be 12 minus the number of whole
          30-day months that have elapsed from the date of the most recent
          Annual Meeting of Stockholders to the date such person is elected to
          be an Outside Director, and the denominator of which shall be 12;

              (iv)  each person who is an Outside Director at the conclusion of
          an Annual Meeting of Stockholders may elect in writing to be granted a
          nonstatutory stock option on the date of such Annual Meeting of
          Stockholders in lieu of all cash compensation to which such Outside
          Director would be entitled for the Board year of the Company
          commencing with such Annual Meeting of Stockholders. The date of such
          Annual Meeting of Stockholders shall also be the date of grant for
          options granted pursuant to this subparagraph 6(a)(iv). The number of
          Common Shares

<PAGE>

          covered by each such option shall be 6,000. Any such election by an
          Outside Director shall be subject to prior approval by the Committee;
          and

               (v)  each person who is elected to be an Outside Director between
          Annual Meetings of Stockholders may elect in writing to be granted a
          nonstatutory stock option in lieu of all cash compensation to which
          such Outside Director would otherwise be entitled for the period
          commencing with the date such person is elected to be an Outside
          Director of the Company by the Board and ending on the date of the
          next Annual Meeting of Stockholders. The date such person is elected
          to be an Outside Director of the Company by the Board shall be the
          date of grant for such options granted pursuant to this
          subparagraph 6(a)(v). The number of Common Shares covered by each such
          option shall be 6,000 multiplied by a fraction, the numerator of which
          shall be 12 minus the number of whole 30-day months that have elapsed
          from the date of the most recent Annual Meeting of Stockholders to the
          date such person is elected to be an Outside Director, and the
          denominator of which shall be 12. Such election by an Outside Director
          shall be subject to prior approval by the Committee.

          (b)  The purchase price of each Common Share subject to an option
     granted to an Outside Director pursuant to this paragraph 6 shall be the
     Fair Market Value of a Common Share on the date of grant.

          (c)(i)    Subject to the provisions of paragraphs 6(d) and 6(e)
     hereof, (x) options granted to Outside Directors pursuant to subparagraph
     6(a)(ii) and (iv) and (y) options granted to Outside Directors pursuant to
     subparagraph 6(a)(i) if the date of grant of such options is the date of an
     Annual Meeting of Stockholders shall vest and become exercisable in
     accordance with the following schedule:

</TABLE>



<PAGE>

          (d)  Notwithstanding the vesting schedules set forth in paragraph 6(c)
     hereof, an option held by an Outside Director shall vest and become
     immediately exercisable upon the latest of (i) the date on which such
     Outside Director attains 62 years of age, (ii) the date on which such
     Outside Director has completed five years of Service (as hereinafter
     defined) and (iii) the first anniversary of the date of grant of such
     option or, if applicable, the Annual Meeting of Stockholders next
     succeeding the Annual Meeting at which such option was granted. Any option
     granted to an Outside Director on or after the first accelerated vesting
     date for such Outside Director shall automatically vest on the Annual
     Meeting of Stockholders next succeeding the Annual Meeting at which such
     option was granted. As used herein, "Service" shall mean service to the
     Company or any subsidiary thereof in the capacity of any advisor,
     consultant, employee, officer or director, and Service as a director from
     an Annual Meeting of Stockholders to the next succeeding Annual Meeting
     shall constitute a year of Service, notwithstanding that such period may
     actually be more or less than one year.

          (e)  Each option granted to an Outside Director pursuant to this
     paragraph 6 and all rights to purchase shares thereunder shall terminate on
     the earliest of:

               (i)  ten years after the date such option is granted;

              (ii)  the expiration of the period specified in paragraph 8(b) or
          8(c), whichever is applicable, after an Outside Director ceases to be
          a director of the Company; or

              (iii) the date, if any, fixed for cancellation pursuant to
          paragraph 9 of this Plan.

In no event shall such option be exercisable at any time after its original
expiration date. When an option is no longer exercisable, it shall be deemed to
have lapsed or terminated and will no longer be outstanding.


7.  MANNER OF EXERCISING OPTIONS.  A person entitled to exercise an option
granted under this Plan may, subject to its terms and conditions and the terms
and conditions of this Plan, exercise it in whole at any time, or in part from
time to time, by delivery to the Company at its principal executive office, to
the attention of its President, of written notice of exercise, specifying the
number of shares with respect to which the option is being exercised,
accompanied by payment in full of the purchase price of the shares to be
purchased at the time. The purchase price of each share on the exercise of any
option shall be paid in full in cash (including check, bank draft or money
order) at the time of exercise or, at the discretion of the holder of the
option, by delivery to the Company of unencumbered Common Shares having an
aggregate Fair Market Value on the date of exercise equal to the purchase price,
or by a combination of cash and such unencumbered Common Shares.  Provided,
however, that a person exercising a stock option shall not be permitted to pay
any portion of the purchase price with stock if, in the opinion of the
Committee, payment in such manner could have adverse financial accounting
consequences for the Company.  No shares shall be issued until full payment
therefor has been made, and the granting of an option to an individual shall
give such individual no rights as a stockholder except as to shares issued to
such individual.

<PAGE>

8.  TRANSFERABILITY AND TERMINATION OF OPTIONS.

          (a)  During the lifetime of an optionee, only such optionee or his or
     her guardian or legal representative may exercise options granted under
     this Plan, and no option granted under this Plan shall be assignable or
     transferable by the optionee otherwise than by will or the laws of descent
     and distribution or pursuant to a domestic relations order as defined in
     the Code or Title I of the Employee Retirement Income Security Act
     ("ERISA"), or the rules thereunder;  provided, however, that any optionee
     may transfer a nonstatutory stock option granted under this Plan to a
     member or members of his or her immediate family (i.e., his or her
     children, grandchildren and spouse) or to one or more trusts for the
     benefit of such family members or partnerships in which such family members
     are the only partners, if (i) the option agreement with respect to such
     options, which must be approved by the Committee, expressly so provides
     either at the time of initial grant or by amendment to an outstanding
     option agreement and (ii) the optionee does not receive any consideration
     for the transfer.  Any options held by any such transferee shall continue
     to be subject to the same terms and conditions that were applicable to such
     options immediately prior to their transfer and may be exercised by such
     transferee as and to the extent that such option has become exercisable and
     has not terminated in accordance with the provisions of the Plan and the
     applicable option agreement.  For purposes of any provision of this Plan
     relating to notice to an optionee or to vesting or termination of an option
     upon the death, disability or termination of employment of an optionee, the
     references to "optionee" shall mean the original grantee of an option and
     not any transferee.

          (b)  During the lifetime of an optionee, an option may be exercised
     only while the optionee is employed by the Company or a parent or
     subsidiary thereof, and only if such optionee has been continuously so
     employed since the date the option was granted, except that:

               (i)  unless otherwise provided in a stock option agreement, an
          option granted to an optionee who is not an Outside Director shall
          continue to be exercisable for three months after termination of such
          optionee's employment but, unless otherwise provided in a stock option
          agreement, only to the extent that the option was exercisable
          immediately prior to such optionee's termination of employment, and
          unless otherwise provided in a stock option agreement, an option
          granted to an optionee who is an Outside Director shall continue to be
          exercisable after such Outside Director ceases to be a director of the
          Company but, unless otherwise provided in a stock option agreement,
          only to the extent that the option was exercisable immediately prior
          to such Outside Director's ceasing to be a director;

              (ii)  in the case of an optionee who is disabled (within the
          meaning of Section 22(e)(3) of the Code) while employed, the option
          granted to such optionee may be exercised within one year after
          termination of such optionee's employment; and
<PAGE>

             (iii)  as to any optionee whose termination occurs following a
          declaration pursuant to paragraph 9 of this Plan, the option granted
          to such optionee may be exercised at any time permitted by such
          declaration.

          (c)  An option may be exercised after the death of the optionee, but
     only within one year after the death of such optionee.

          (d)  In the event of the disability (within the meaning of
     Section 22(e)(3) of the Code) or death of an optionee, any option granted
     to such optionee that was not previously exercisable shall become
     immediately exercisable in full if the disabled or deceased optionee shall
     have been continuously employed by the Company or a parent or subsidiary
     thereof between the date such option was granted and the date of such
     disability, or, in the event of death, a date not more than three months
     prior to such death.

9.  DISSOLUTION, LIQUIDATION, MERGER.  In the event of (a) a proposed merger or
consolidation of the Company with or into any other corporation, regardless of
whether the Company is the surviving corporation, unless appropriate provision
shall have been made for the protection of the outstanding options granted under
this Plan by the substitution, in lieu of such options, of options to purchase
appropriate voting common stock (the "Survivor's Stock") of the corporation
surviving any such merger or consolidation or, if appropriate, the parent
corporation of the Company or such surviving corporation, or, alternatively, by
the delivery of a number of shares of the Survivor's Stock which has a Fair
Market Value as of the effective date of such merger or consolidation equal to
the product of (i) the excess of (x) the Event Proceeds per Common Share (as
hereinafter defined) covered by the option as of such effective date, over
(y) the option price per Common Share, times (ii) the number of Common Shares
covered by such option, or (b) the proposed dissolution or liquidation of the
Company (such merger, consolidation, dissolution or liquidation being herein
called an "Event"), the Committee shall declare, at least ten days prior to the
actual effective date of an Event, and provide written notice to each optionee
of the declaration, that each outstanding option, whether or not then
exercisable, shall be cancelled at the time of, or immediately prior to the
occurrence of, the Event (unless it shall have been exercised prior to the
occurrence of the Event) in exchange for payment to the holder of each cancelled
option, within ten days after the Event, of cash equal to the amount (if any),
for each Common Share covered by the cancelled option, by which the Event
Proceeds per Common Share (as hereinafter defined) exceeds the exercise price
per Common Share covered by such option. At the time of the declaration provided
for in the immediately preceding sentence, each option shall immediately become
exercisable in full and each holder of an option shall have the right, during
the period preceding the time of cancellation of the option, to exercise his or
her option as to all or any part of the Common Shares covered thereby. Each
outstanding option granted pursuant to this Plan that shall not have been
exercised prior to the Event shall be cancelled at the time of, or immediately
prior to, the Event, as provided in the declaration, and this Plan shall
terminate at the time of such cancellation, subject to the payment obligations
of the Company provided in this paragraph 9. For purposes of this paragraph,
"Event Proceeds per Common Share" shall mean the cash plus the fair market
value, as determined in good faith by the Committee, of the non-cash
consideration to be received per Common Share by the stockholders of the Company
upon the occurrence of the Event.


<PAGE>

10.  SUBSTITUTION OPTIONS.  Options may be granted under this Plan from time to
time in substitution for stock options held by employees of other corporations
who are about to become employees of the Company or a subsidiary of the Company,
or whose employer is about to become a subsidiary of the Company, as the result
of a merger or consolidation of the Company or a subsidiary of the Company with
another corporation, the acquisition by the Company or a subsidiary of the
Company of all or substantially all the assets of another corporation or the
acquisition by the Company or a subsidiary of the Company of at least 50% of the
issued and outstanding stock of another corporation. The terms and conditions of
the substitute options so granted may vary from the terms and conditions set
forth in this Plan to such extent as the Board at the time of the grant may deem
appropriate to conform, in whole or in part, to the provisions of the stock
options in substitution for which they are granted, but with respect to stock
options which are incentive stock options, no such variation shall be permitted
which affects the status of any such substitute option as an incentive stock
option under Section 422A of the Code.

11.  TAX WITHHOLDING.  Delivery of Common Shares upon exercise of any
nonstatutory stock option granted under this Plan shall be subject to any
required withholding taxes. A person exercising such an option may, as a
condition precedent to receiving the Common Shares, be required to pay the
Company a cash amount equal to the amount of any required withholdings. In lieu
of all or any part of such a cash payment, the Committee may, but shall not be
required to, permit the optionee to elect to cover all or any part of the
required withholdings, and to cover any additional withholdings up to the amount
needed to cover such optionee's full FICA and federal, state and local income
tax liability with respect to income arising from the exercise of the option,
through a reduction of the number of Common Shares delivered to the person
exercising the option or through a subsequent return to the Company of shares
delivered to the person exercising the option.

12.  TERMINATION OF EMPLOYMENT.  Neither the transfer of employment of an
optionee between any combination of the Company, a parent corporation or a
subsidiary thereof, nor a leave of absence granted to such optionee and approved
by the Committee, shall be deemed a termination of employment for purposes of
this Plan. The terms "parent" or "parent corporation" and "subsidiary" as used
in this Plan shall have the meaning ascribed to "parent corporation" and
"subsidiary corporation", respectively, in Sections 424(e) and (f) of the Code.

13.  OTHER TERMS AND CONDITIONS.  The Committee shall have the power, subject to
the other limitations contained herein, to fix any other terms and conditions
for the grant or exercise of any option under this Plan. Nothing contained in
this Plan, or in any option granted pursuant to this Plan, shall confer upon any
optionee any right to continued employment by the Company or any parent or
subsidiary of the Company or limit in any way the right of the Company or any
such parent or subsidiary to terminate an optionee's employment at any time.

14.  OPTION AGREEMENTS.  All options granted under this Plan shall be evidenced
by a written agreement in such form or forms as the Committee may from time to
time determine, which agreement shall, among other things, designate whether the
options being granted thereunder are nonstatutory stock options or incentive
stock options under Section 422 of the Code.

15.  AMENDMENT AND DISCONTINUANCE OF PLAN.  The Board may at any time amend,
suspend or discontinue this Plan; provided, however, that no amendment by the
Board shall, without further

<PAGE>

approval of the Stockholders of the Company, if required in order for the Plan
to continue to meet the requirements of the Code:

     (a)  change the persons eligible to receive options;

     (b)  except as provided in paragraph 3 hereof, increase the total number of
     Common Shares of the Company which may be made subject to options granted
     under this Plan;

     (c)  except as provided in paragraph 3 hereof, change the minimum purchase
     price for the exercise of an option; or

     (d)  extend the term of this Plan beyond December 1, 2006.

No amendment to this Plan shall, without the consent of the holder of the
option, alter or impair any options previously granted under this Plan.

         16.  EFFECTIVE DATE.  This Plan shall be effective July 26, 1989.

FACTORS THAT MAY AFFECT FUTURE RESULTS  >>

   Certain statements made herein, which are summarized below, are
forward-looking statements that involve risks and uncertainties, and actual
results may be materially different. Factors that could cause actual results to
differ include, but are not limited to, those identified as follows:

- - DIGI'S STRATEGY OF ENHANCING SEASONED BUSINESSES WHILE ACHIEVING SIGNIFICANT 
  MARKET SHARE IN NEW HIGH-GROWTH MARKETS SUCH AS REMOTE ACCESS AND INTERNET   
  TELEPHONY AND THE FISCAL 1999 FOCUS ON ACCELERATING BUSINESS GROWTH AND LAYING
  A FOUNDATION FOR CONSISTENT EARNINGS IMPROVEMENT SHOULD BE CHARACTERIZED AS  
  FORWARD-LOOKING AND, AS SUCH, MAY INVOLVE RISKS AND UNCERTAINTIES.

- - THE EXPECTATION OF CONTINUED GROWTH IN DEMAND FOR AND SALES OF THE COMPANY'S 
  REMOTE ACCESS, INTERNET TELEPHONY AND VOIP PRODUCTS, THE COMPANY'S ABILITY TO
  PROVIDE PRODUCTS THAT TAKE ADVANTAGE OF NEW MARKET OPPORTUNITIES AND THE  
  COMPANY'S BELIEF THAT NEW PRODUCTS WILL BE PROFITABLE -- This expectation may
  be impacted by general market conditions and competitive conditions within 
  these markets, development and acceptance of new products offered by the   
  Company and the introduction of products by competitors in these markets.

- - THE EXPECTATION THAT ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT WILL REACH 
  TECHNOLOGICAL FEASIBILITY AND LEAD TO NEW USB PRODUCTS IN 1999 AND NEW   
  INTERNET PROTOCOL TELEPHONY PRODUCTS IN 2000 AND 2001 WHICH WILL BENEFIT THE 
  COMPANY IN THE FUTURE AND THE COMPANY'S ESTIMATION OF THE COSTS ASSOCIATED  
  WITH SUCH DEVELOPMENT -- This expectation may be impacted by unanticipated  
  expenses or obstacles to development, general market conditions or changes in
  competitive conditions.

- - THE COMPANY'S ASSUMPTIONS REGARDING REVENUE GROWTH, COST OF SALES, COST   
  SAVINGS AND THE WEIGHTED AVERAGE COST OF CAPITAL USED TO VALUE IN-PROCESS  
  RESEARCH AND DEVELOPMENT ACQUIRED IN RECENT ACQUISITIONS -- These assumptions 
  may be impacted by general market conditions, unanticipated changes in   
  expenses or sales, delays in the development of new products, the useful lives
  of such products once developed, component shortages, and technological   
  advances and other changes in competitive conditions that would affect the  
  value of the acquired in-process research and development.

- - THE BELIEF THAT THE COMPANY'S CURRENT FINANCIAL RESOURCES, CASH GENERATED 
  FROM OPERATIONS AND THE COMPANY'S POTENTIAL CAPACITY FOR DEBT AND/OR EQUITY 
  FINANCING WILL BE SUFFICIENT TO FUND CURRENT AND ANTICIPATED BUSINESS   
  OPERATIONS -- Changes in anticipated operating results, credit availability 
  and equity market conditions may further enhance or inhibit the Company's   
  ability to maintain or raise appropriate levels of cash.  

- - THE COMPANY'S BELIEF THAT EVALUATIONS AND MODIFICATIONS OF YEAR 2000    
  COMPLIANCE MATTERS, INCLUDING YEAR 2000 COMPLIANCE OF THIRD PARTY SUPPLIERS, 
  WILL NOT HAVE A MATERIAL ADVERSE EFFECT ON THE COMPANY'S OPERATIONS OR       
  FINANCIAL POSITION -- This belief may be impacted by presently unanticipated 
  delays in assessment or remediation, unanticipated increases in costs or non-
  compliance by third parties.

- - THE COMPANY'S EXPECTATION THAT VARIOUS RESTRUCTURING ACTIVITIES IN CONNECTION
  WITH THE ACQUISITION OF ITK INTERNATIONAL, INC. AND CENTRAL DATA CORPORATION 
  WILL BE COMPLETED ACCORDING TO SCHEDULE -- This expectation may be impacted by
  presently unanticipated delays or expenses.


NET SALES  >>
   
     The $17.3 million increase in net sales from 1997 to 1998 and the $27.6 
million decrease in net sales from 1996 to 1997 occurred within the Company's 
principal product groups as follows:

</TABLE>

     Net sales in fiscal 1998 increased from fiscal 1997 largely because the
Company reduced inventory levels in the North American distribution channel
throughout 1997 and into the first quarter of fiscal 1998. This resulted in a
net increase in sales within the distribution channel during the remainder of
1998. In addition, during the third and fourth quarters of fiscal 1998, the
Company gave extended credit terms to North American distributors which provided
incentive for them to increase their purchases. Such incented increases in sales
to these customers could result in a decrease in sales to these customers in
fiscal year 1999. The Company's fiscal 1998 net sales also increased due to the
addition of $9.7 million in fourth-quarter sales made by newly acquired ITK
International, Inc. (ITK) and Central Data Corporation (CDC). Net sales in 1997
declined from 1996 primarily due to the Company's inventory reductions in the
North American distribution channel.
   
     Net sales to original equipment manufacturers (OEMs), as a percentage of
total net sales, declined to 22.2% versus 23.5% in 1997. The decrease was
principally a function of higher net sales to the distribution market. Net sales
to OEMs for 1996 were 20.3% of total sales. 

     Net sales to the distribution markets, as a percentage of total net sales,
increased to 69.3% in 1998, compared to 64.1% in 1997. This increase was a
result of the Company's 1997 inventory reductions in the North American
distribution channel, as previously discussed. Net sales to the distribution
market for 1996 represented 65.5% of total net sales.

                    18
DIGI INTERNATIONAL INC.

<PAGE>

     During fiscal years 1998, 1997 and 1996, the Company's net sales to
customers outside the United States, primarily in Europe, were approximately
$38.5 million, $39.6 million and $39.9 million, respectively, comprising
approximately 21.1%, 23.9% and 20.0% of total net sales.


GROSS MARGIN  >>
   
     Gross margin in 1998 rose to 51.6%, compared to 48.4% in 1997. The increase
was due to more stringent cost control and favorable product mix. Gross margin
also benefited as net sales of historically lower-margin products -- largely OEM
and certain physical layer products -- declined as a percentage of total net
sales. Offsetting the favorable sales mix were increases in inventory valuation
reserves, sales discounts granted, and a higher proportion of lower margin
products sold in the fourth quarter of fiscal 1998 due to the acquisition of CDC
and ITK. Gross margins on total ITK and CDC sales in the fourth quarter of
fiscal 1998 were 44.0%. Gross margin in 1996 was 51.8%. The 1997 gross margin
decline was principally due to the increase of OEM and physical layer product
net sales as a percentage of total net sales as sales to the distribution
markets were intentionally reduced in 1997. The Company increased its reserves
for excess and obsolete inventories approximately $2.6 million in 1998. In 1997,
these reserves increased approximately $1.5 million from the 1996 level.


OPERATING EXPENSES  >>
   
     Operating expenses in 1998 declined 5.0% from 1997, excluding acquired
in-process research and development charges of $39,200,000 recorded in 1998 and
the restructuring charges recorded in 1998 and 1997 of $1,020,000 and
$10,471,482, respectively. The operating expense decline reflected reductions in
the workforce, decreased marketing costs and cost savings achieved through the
consolidation of U.S. research and development efforts, offset by CDC and ITK
operating expenses of $3.8 million. General and administrative expenses declined
in 1998 due to workforce reductions and cost-saving initiatives. Operating
expenses in 1997 declined 7.5% from 1996, excluding restructuring charges. The
decline resulted from cost-saving measures similar to those executed in 1998.
General and administrative expenses increased 27.0% in 1997 from 1996 due to an
increase in the provision for losses on accounts receivable, cost of management
information systems and increased facilities expenditures.
   
     The $1,020,000 restructuring charge recorded in the fiscal 1998 fourth
quarter was associated with a board-approved plan to consolidate existing
offices in Germany with those acquired from ITK. The charge consists principally
of rent, contractual payments on office equipment, write-offs of leasehold
improvements and severance costs associated with the elimination of six
positions. These activities are expected to be completed in the second quarter
of fiscal 1999. No portion of this liability has been paid as of September 30,
1998.

     The $10,471,482 restructuring charge recorded in the fiscal 1997 second
quarter was related to a board-approved plan to consolidate operations and
reduce costs and expenses. The restructuring charge consisted of $1,259,769 in
net cash expenditures (primarily severance), all of which had been paid as of
September 30, 1997, and $9,211,713 resulting from the write-down of asset
carrying values.


ACQUIRED IN-PROCESS 
RESEARCH AND DEVELOPMENT  >>


ACQUISITION OF ITK INTERNATIONAL, INC.:
   
     In July 1998, the Company acquired all of the outstanding common stock of
ITK. The transaction was accounted for using the purchase method of accounting.
Accordingly, the purchase price was allocated to the estimated fair value of
assets acquired and liabilities assumed, including estimated restructuring and
integration costs of $3,484,000.

     Components of the purchase consideration, including related transaction
costs, consist of $14,767,154 in cash, the Company's common stock with a market
value of $11,671,229 and $1,276,436 of replacement stock options issued by the
Company to ITK option holders. The cash and the Company's common stock were
issued in exchange for outstanding shares of ITK's common stock and the
Company's stock options were issued in exchange for the outstanding ITK common
stock options. The value of the Company's common stock issued was based on a per
share value of approximately $20.25, which was the market value of the Company's
common stock on the date the Company and ITK agreed to the terms of the
purchase. The value of the Company's common stock options is based on the excess
of the market value of the Company's common stock over the option exercise
prices on the date that these options were granted to ITK employees. The
purchase price will increase by $963,323 if the unvested portion of stock
options granted to the ITK employees vest. Such amount has been recorded as
unearned stock compensation.

     Valuation of the intangible assets acquired was determined by an
independent appraisal company and consists of purchased in-process research and
development (IPR&D), proven technology and an assembled workforce. The purchase
price exceeded the estimated fair value of tangible and intangible assets
acquired by $7,130,253, which was recorded as goodwill.

     The table below is an analysis of the purchase price allocation.

</TABLE>

     Management, based upon an independent appraisal, estimates that $26,000,000
of the purchase price represents the fair value of purchased IPR&D that had not
yet reached technological feasibility and has no alternative future use. The
amount allocated to IPR&D was expensed as a non-recurring, non-tax-deductible
charge upon consummation of the acquisition.
   
     The Company is using the acquired in-process research and development to
create new products in the area of Internet Protocol telephony, which will
become part of the Company's product line over the next several years. The
Company anticipates the initial Internet Protocol telephony products developed
from acquired in-process research and development will be released in 2000 and
2001. The Company expects that the acquired in-process research and development
will reach technological feasibility, but there can be no assurance that the
commercial viability of these products will be achieved.

     The nature of the efforts required to develop the acquired in-process 
research and development into commercially viable products principally 
relates to the completion of all planning, designing, prototyping, 
verification and testing activities that are necessary to establish that the 
product can be produced to meet its design specifications, including 
functions, features and technical performance requirements. The estimated 
costs to be incurred to develop the purchased in-process technology into 
commercially viable products are approximately $24,800,000 in the aggregate 
through the year 2007, consisting of $300,000 in 1998; $2,000,000 in 1999; 
$4,800,000 in 2000; $4,800,000 in 2001; $4,300,000 in 2002; $3,200,000 in 
2003; $2,500,000 in 2004; $1,400,000 in 2005; $900,000 in 2006 and $600,000 
in 2007.

     The value assigned to purchased in-process research and development was
determined through independent appraisers, who projected cash flows related to
future products expected to be derived once technological feasibility is
achieved, including costs to complete the development of the technology and the
future revenues and costs which are expected to result from commercialization of
the products. These cash flows were discounted back to their present values. The
resulting net cash flows from such projects are based on estimates made by the
Company's management of revenues, cost of sales, research and development costs,
selling, general and administrative costs, and income taxes resulting from such
projects. These estimates are based on the following assumptions:

- - The estimated revenues are based upon projected average annual revenue growth
  rates from future products expected to be derived once technological
  feasibility is achieved of between 18% and 65% during the period from 2000
  through 2005. Estimated total revenues expected from products to be developed
  using purchased in-process research and development peak in the year 2005 and
  decline rapidly in 2006 and 2007 as other new products are expected to enter
  the market. These projections are based on estimates made by the Company's
  management of market size and growth (which are supported by independent
  market data), expected trends in technology and the nature and expected
  timing of new product introductions by ITK and its competitors. These
  estimates also include growth related to the Company utilizing certain ITK
  technologies under development in conjunction with the Company's products,
  the Company marketing and distributing the resulting products through the
  Company's resellers, and the Company enhancing the market's response to ITK's
  products by providing incremental financial support and stability.

- - The estimated cost of sales as a percentage of revenues is expected to be
  lower than ITK's cost of sales would have been on a stand-alone basis
  primarily due to the Company's expected ability to achieve more favorable
  pricing from key component vendors and production efficiencies due to
  economies of scale achieved through combined operations.

- - The estimated selling, general and administrative costs are expected to more
  closely approximate the Company's cost structure (approximately 34% of
  revenues in 1997), which is lower than ITK's cost structure (approximately
  81% of revenues in fiscal 1997). Cost savings are expected to result
  primarily from: (a) the changes related to certain restructuring actions
  including the shut-down of certain existing ITK facilities and a reduction in
  certain administrative ITK employees; (b) the distribution of ITK's products
  through the Company's resellers (i.e., sales of higher volume products with
  lower direct selling costs); and (c) efficiencies due to economies of scale
  through combined operations (i.e., consolidated marketing and advertising
  programs). These cost savings are expected to be realized primarily in 2000
  and thereafter.

- - Discounting the net cash flows back to their present values is based on the
  weighted averages cost of capital (WACC). The WACC calculation produces the
  average required rate of return of an investment in an operating enterprise,
  based on various required rates of return from investments in various areas
  of that enterprise. The WACC assumed for the Company, as a corporate business
  enterprise, is 14%. The discount rate used in discounting the net 

                    20
DIGI INTERNATIONAL INC.

<PAGE>

cash flows from purchased in-process technology was 30%. This discount rate is
higher than the WACC due to the inherent uncertainties in the estimates
described above including the uncertainty surrounding the successful development
of the purchased in-process research and development, the useful life of such
completed research and development, the profitability levels of such completed
research and development and the uncertainty of technological advances that are
unknown at this time. If these products are not successfully developed, the
sales and profitability of the combined company may be adversely affected in
future periods. Additionally, the value of other intangible assets acquired may
become impaired. The Company expects to begin to benefit from the purchased
in-process research and development in 2000.

     The identifiable intangible assets of $12,700,000 included in the purchase
price allocation set forth above are comprised of proven technology with an
appraised fair value of $11,300,000 and an assembled workforce with an appraised
fair value of $1,400,000, which have estimated useful lives of five years and
six years, respectively. The remaining unallocated purchase price represents
goodwill which is being amortized over seven years. 


ACQUISITION OF CENTRAL DATA CORPORATION:

     In July 1998, the Company acquired all of the outstanding common stock of
CDC. The transaction was accounted for using the purchase method of accounting.
Accordingly, the purchase price was allocated to the estimated fair value of
assets acquired and liabilities assumed, including estimated restructuring and
integration costs of $750,000.

     Components of the purchase consideration, including related transaction
costs, consist of $14,261,965 in cash, the Company's common stock with a market
value of $4,039,475 and $891,184 of replacement stock options issued by the
Company to CDC option holders. The cash and the Company's common stock were
issued in exchange for outstanding shares of CDC's common stock and the
Company's stock options were issued in exchange for the outstanding CDC common
stock options. The value of the Company's common stock issued was based on a per
share value of approximately $20.25, which was the market value of the Company's
common stock on the date the Company and CDC agreed to the terms of the
purchase. The value of the Company's common stock options is based on the excess
of the market value of the Company's common stock over the option exercise
prices on the date that these options were granted to CDC employees. The
purchase price will increase by $1,230,683 if the unvested portion of stock
options granted to the CDC employees vest. Such amount has been recorded as
unearned stock compensation.

     Valuation of the intangible assets acquired was determined by an
independent appraisal company and consists of purchased in-process research and
development (IPR&D), proven technology and an assembled workforce. The purchase
price exceeded the estimated fair value of tangible and intangible assets
acquired by $1,034,833, which was recorded as goodwill. 

     The table below is an analysis of the purchase price allocation.

Universal Serial Bus, which is emerging as a new industry-standard serial
communications bus architecture, and which will become part of the Company's
product line over the next several years. The Company anticipates that Universal
Serial Bus products developed from acquired in-process research and development
will be released in 1999. The Company expects that the acquired in-process
research and development will reach technological feasibility, but there can be
no assurance that the commercial viability of these products will be achieved.
   
     The nature of the efforts required to develop the acquired in-process
research and development into commercially viable products principally relates
to the completion of all planning, designing, prototyping, verification and
testing activities that are necessary to establish that the product can be
produced to meet its design specifications, including functions, features and
technical performance requirements. The estimated costs to be incurred to
develop the purchased in-process technology into commercially viable products
are approximately $5,000,000 in the aggregate through the year 2004, consisting
of $200,000 incurred during the period from July 1998 through September 30,
1998, and $800,000 per year from 1999 to 2004.

     The value assigned to purchased in-process research and development was
determined by independent appraisers, who projected cash flows related to future
products expected to be derived once technological feasibility is achieved,
including costs to complete the development of the technology and the future
revenues and costs which are expected to result from commercialization of the
products. These cash flows were discounted back to their present

values. The resulting net cash flows from such projects are based on estimates
made by the Company's management of revenues, cost of sales, research and
development costs, selling, general and administrative costs, and income taxes
resulting from such projects. These estimates are based on the following
assumptions:

- - The estimated revenues are based upon projected average annual revenue growth
  rates from future products expected to be derived once technological
  feasibility is achieved of between 9% and 52% during the period from 2000
  through 2002. Estimated total revenues expected from products to be developed
  using purchased in-process research and development peak in the year 2002 and
  decline rapidly in 2003 and 2004 as other new products are expected to enter
  the market. These projections are based on estimates made by the Company's
  management of market size and growth (which are supported by independent
  market data), expected trends in technology and the nature and expected
  timing of new product introductions by CDC and its competitors. These
  estimates also include growth related to the Company utilizing certain CDC
  technologies under development in conjunction with the Company's products,
  the Company marketing and distributing the resulting products through the
  Company's resellers, and the Company enhancing the market's response to CDC's
  products by providing incremental financial support and stability.

- - The estimated cost of sales as a percentage of revenues is expected to be
  lower than CDC's cost of sales would have been on a stand-alone basis
  primarily due to the Company's expected ability to achieve more favorable
  pricing from key component vendors and production efficiencies due to
  economies of scale achieved through combined operations.

- - The estimated selling, general and administrative costs are expected to
  remain at approximately the same levels for the Company and CDC
  (approximately 33% of revenues for both the Company and CDC in 1997).

- - Discounting the net cash flows back to their present values is based on the
  weighted average cost of capital (WACC). The WACC calculation produces the
  average required rate of return of an investment in an operating enterprise,
  based on various required rates of return from investments in various areas
  of that enterprise. The WACC assumed for the Company, as a corporate business
  enterprise, is 14%. The discount rate used in discounting the net cash flows
  from purchased in-process technology was 30%. This discount rate is higher
  than the WACC due to the inherent uncertainties in the estimates described
  above including the uncertainty surrounding the successful development of the
  purchased in-process research and development, the useful life of such
  completed research and development, the profitability levels of such
  completed research and development and the uncertainty of technological
  advances that are unknown at this time.

     If these products are not successfully developed, the sales and
profitability of the combined Company may be adversely affected in future
periods. Additionally, the value of other intangible assets acquired may become
impaired. The Company expects to begin to benefit from the purchased in-process
research and development in 1999.
   
     The identifiable intangible assets of $4,100,000 included in the purchase
price allocation set forth above are comprised of proven technology with an
appraised fair value of $3,700,000, and an assembled workforce with an appraised
fair value of $400,000, which have estimated useful lives of five years and six
years, respectively. The remaining unallocated purchase price represents
goodwill, which is being amortized over seven years.

     The Company has responded to questions provided by the staff of the
Securities and Exchange Commission about the Company's write-offs of acquired
in-process research and development in connection with the ITK and CDC
acquisitions. As of December 11, 1998, the Company had not received any further
comments from the Securities and Exchange Commission.


OTHER INCOME  >>
   
     Other income for 1998 increased approximately $3.0 million, as the Company
earned higher interest income on its increased cash and cash equivalent
balances. Other income also included a fiscal 1998 third-quarter reversal of a
$1.4 million previously accrued obligation related to lease guarantees for
AetherWorks Corporation. As discussed in the next item below, the obligation is
no longer required because the Company is no longer the primary guarantor for
these leases.

AETHERWORKS CORPORATION
NET LOSS AND WRITE-OFF   >>
   
     In connection with the Company's previously purchased $13.8 million of
convertible notes from AetherWorks Corporation, in May 1998 the Company
exchanged such notes for a non-interest bearing $8.0 million non-convertible
note and was released from all of its guarantees of certain lease obligations of
AetherWorks. Due to significant uncertainty as to its collectibility, the $8.0
million note, which matures in 2001, has been recorded by the Company as having
no carrying value. In fiscal 1997 and 1996, the Company used the equity method
to account for its investment in AetherWorks and recorded net losses of $5.8
million and $3.6 million, respectively. These net losses represent 100% of
AetherWorks' losses for those years. The percentage of AetherWorks' net losses
included in the Company's financial statements was based upon the percentage of
financial support provided by the Company (versus other investors) during those
years. The Company wrote off its investment in AetherWorks as of September 30,
1997, and recorded a $5.8 million charge, composed of its $2.4 million remaining
investment, its 
   
                    22
DIGI INTERNATIONAL INC.

<PAGE>

$2.0 million remaining obligation to purchase additional notes and $1.4 million
for the obligation to guarantee certain AetherWorks leases. The Company no
longer has any funding obligations or any potential equity interest in or
management control over AetherWorks. Consequently, the Company has not included
any of AetherWorks' net losses in its results of operations during fiscal 1998.


INCOME TAXES  >>
   
     The Company recorded a $9.7 million tax provision for 1998, even though it
has reported a pre-tax loss for the year. This tax provision was required
primarily because the write-off of acquired in-process research and development
and the amortization of certain intangible assets and goodwill acquired in the
purchase of ITK and CDC is not deductible for income tax reporting purposes. In
1997, the Company recorded a $0.1 million tax provision, while reporting a
pre-tax loss for that year. That provision was necessary due to the
non-deductibility of certain intangible assets written off as part of the
restructuring charge, the AetherWorks net losses and the related investment
write-off. In addition, the Company had also provided additional provision in
connection with an IRS examination of certain tax returns filed in prior years.
In 1996, the Company recorded a $7.5 million income tax provision at a higher
rate than the federal statutory rate due primarily to the nondeductability of
the AetherWorks net losses.


INFLATION  >>
   
     The Company believes inflation has not had a material effect on its
operations or its financial condition.


LIQUIDITY AND CAPITAL RESOURCES  >>
   
     The Company has financed its operations principally with funds generated
from operations, and, in prior years, with proceeds from earlier public
offerings. Investing activities in 1998 consisted of the acquisitions of ITK and
CDC for a combined purchase price of $46.9 million, including the issuance of
$15.7 million of common stock, $2.2 million of replacement stock options, and
cash payments of $29 million. In connection with the acquisitions, the Company
also assumed $22.1 million in line of credit obligations and long-term debt in
the fourth quarter of fiscal 1998, reflecting the outstanding debt of ITK and
CDC. 
   
     Other investing activities in 1998 consisted primarily of purchases of $5.8
million of equipment and capital improvements, including a new enterprise-wide
computer system. In addition, the final payments totaling $2 million for
AetherWorks Corporation notes were made in 1998.

     In September 1998, the Board of Directors authorized a program to
repurchase up to one million shares of the Company's common stock for use in the
Company's benefit plans. As of September 30, 1998, 15,000 shares had been
repurchased under this program.

     Investing activities in 1997 consisted of purchases of $8.8 million of 
equipment and capital improvements and the purchase of $6.5 million of 
additional convertible notes from AetherWorks Corporation.

     At September 30, 1998, the Company had working capital of $37.9 million and
debt totaling $22.1 million. The Company maintains lines of credit with various
financial institutions providing for borrowings of up to $25,707,000, depending
upon levels of eligible accounts receivable and inventories. As of September 30,
1998, $10,707,000 had been borrowed under these lines of credit. The Company's
management believes that current financial resources, cash generated from
operations and the Company's potential capacity for debt and/or equity financing
will be sufficient to fund current and future business operations. 


FOREIGN CURRENCY TRANSLATION  >>
   
     Substantially all of the Company's foreign transactions are negotiated,
invoiced and paid in U.S. dollars -- except for approximately $5.8 million in
Deutschemark-denominated sales made through the Company's newly-acquired
subsidiary, ITK. In future periods, a significant portion of sales made through
ITK will be made in Deutschemarks until full integration of the "euro" is
achieved. The Company has not implemented a hedging strategy to reduce the risk
of foreign currency translation exposures, which management does not believe to
be significant based on the scope of the Company's foreign operations as of
September 30, 1998.
   
     Effective January 1, 1999, eleven states of the European Union will convert
to a common currency, called the "euro." This action will most likely cause the
majority of the Company's European transactions to be negotiated, invoiced and
paid in "euros." The conversion will most likely add currency exchange costs and
risks, although such costs and risks are not quantifiable at this time.


YEAR 2000 ISSUES  >>
   
     The Company began a comprehensive project in 1996 to prepare its products
and its internal computer systems for the year 2000. Most of the Company's
products are year 2000 compliant because there is very little or no date
processing involved. Certain products, including end-of-life versions, do
require customer action such as a patch or version upgrade to be compliant.
These products are being identified, and the Company is in the process of
notifying impacted customers. 
   
     The Company believes its implementation of a new enterprise-wide
information management system, principally installed to improve operating
efficiency, will address the Company's internal year 2000 compliance issues.
Because of the acquisitions of ITK and CDC, the world-wide rollout of this
system will not be completed until the late summer of calendar year 1999. If
necessary conversions are not completed on a timely basis, the year 2000 could
have 

                                                         23

<PAGE>

a material adverse effect on the Company's operations. Overall, management
believes the year 2000 will not have a significant impact on operations. 

     The Company plans to continue with remediation and testing efforts with
both its products and internal systems to further mitigate any risks associated
with the year 2000. At this time, the Company believes it is unnecessary to
adopt a contingency plan covering the possibility that the year 2000 project
will not be completed in a timely manner, but, as part of the overall project,
the Company will continue to assess the need for a contingency plan based on the
Company's periodic evaluation of target dates for the completion of the year
2000 project. 

     The Company faces risk to the extent that suppliers of products and
services purchased by the Company and others with whom the Company transacts
business on a world-wide basis do not have business products and services that
comply with year 2000 requirements. The Company has obtained assurances from
most of its key suppliers that their products and services are year 2000
compliant. In the event any such third parties cannot, in a timely manner,
provide the Company with products and services that meet the year 2000
requirements, the Company's operating results could be materially adversely
affected. 

     The costs associated with the year 2000 project are minimal and are not
incremental to the Company, but include temporary reallocation of existing
resources. Although the Company believes that the remaining cost of year 2000
modifications for both internal-use systems and the Company's products are not
material, there can be no assurances that various factors relating to the year
2000 compliance issues, including litigation, will not have a material adverse
effect on the Company's business, operating results, or financial position.


NEW ACCOUNTING STANDARDS  >>
   
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income." The
statement establishes standards for the reporting and display of comprehensive
income and its components. Comprehensive income is defined as the change in
equity of a business enterprise during a period from transactions and other
events and circumstances from non-owner sources. It includes all changes in
equity during a period except those resulting from investments by owners and
distributions to owners. This standard will require that an enterprise display
an amount representing total comprehensive income for the period. Statement No.
130 will be initially effective for the first quarter of the Company's fiscal
year ending September 30, 1999. Adoption of Statement of Financial Accounting
Standards No. 130 will not impact the results of operations or the financial
position of the Company.
   
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information," which supersedes Statement No. 14. This
statement changes the way that public business enterprises report segment
information, including financial and descriptive information about their
operating segments, in annual financial statements and would require that those
enterprises report selected segment information in interim financial reports to
stockholders. Operating segments are defined as revenue-producing components of
the enterprise which are generally used internally for evaluating segment
performance. Statement No. 131 will be effective for the Company beginning with
the first quarter of the Company's fiscal year ending September 30, 1999.
Management has not yet completed its analysis of the effects of Statement No.
131 on its financial reporting. 

     In June 1998, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 133, "Accounting for Derivative 
Instruments and Hedging Activities." Statement No. 133 will be effective for 
the Company beginning with the Company's fiscal year ending September 30, 
2000. As the Company presently has no derivative instruments and is not 
involved in hedging activity, the Company does not expect the adoption of 
Statement No. 133 to have an impact on the results of operations or the 
financial position of the Company. 

     In October 1997, Statement of Position 97-2, "Software Revenue Recognition"
(SOP 97-2), was issued. SOP 97-2 provides guidance on when revenue should be
recognized and in what amounts for licensing, selling, leasing or otherwise
marketing computer software. SOP 97-2 will become effective for the Company's
fiscal year ending September 30, 1999. The adoption of SOP 97-2 is not expected
to have a significant impact on the results of operations or financial position
of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  >>


1 >> SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


BUSINESS DESCRIPTION

     Digi International is a leading worldwide provider of data communications
products for open systems, server-based remote access, Internet telephony, and
local area network (LAN) applications. Digi's communications products support a
broad range of server platforms and network operating systems that enable people
to access information.

     Digi's products are marketed through a global network of distributors, 
system integrators, original equipment manufacturers (OEMs), as well as 
thousands of value-added resellers (VARs).


PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated in consolidation.


CASH EQUIVALENTS AND MARKETABLE SECURITIES

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents, while those
having original maturities in excess of three months are classified as
marketable securities and generally consist of U.S. Government and U.S.
Government-backed obligations and high-grade commercial paper. Marketable
securities classified as held to maturity are carried at amortized cost.
Marketable securities classified as trading or available-for-sale are recorded
at market value. The Company had no marketable securities as of September 30,
1998 or 1997.


REVENUE RECOGNITION

     Sales are recognized to distributors, VARs, and end-users at the date of
shipment. Estimated warranty costs and customer returns are recorded at the time
of sale.

     The Company offers rebates to authorized domestic and international
distributors and authorized resellers. The rebates are incurred based on the
level of sales to the respective distributors and resellers, and are charged to
operations in the same period as the corresponding sales.


INVENTORIES

     Inventories are stated at the lower of cost or fair market value, with cost
determined on the first-in, first-out method. Fair market value for raw
materials is based on replacement cost and for other inventory classifications
based on net realizable value. Appropriate consideration is given to
deterioration, obsolescence and other factors in evaluating net realizable
value.


PROPERTY, EQUIPMENT AND IMPROVEMENTS

     Property, equipment and improvements are carried at cost. Depreciation is
provided by charges to operations using the straight-line method based on
estimated useful lives, ranging from three to 39 years.

     Expenditures for maintenance and repairs are charged to operations as
incurred, while major renewals and betterments are capitalized. The assets and
related accumulated depreciation accounts are adjusted for asset retirements and
disposals with the resulting gain or loss included in operations.

     The Company's cost of business process reengineering activities, whether
done internally or by third parties, is expensed as incurred.


INTANGIBLE ASSETS

     Purchased technology, license agreements, covenants not to compete and
other intangible assets are recorded at cost. Goodwill represents the excess of
cost over the fair value of identifiable assets acquired and is being amortized
on a straight-line basis over periods ranging from five to 15 years. All other
intangible assets are amortized on a straight-line basis over their estimated
useful lives of one to seven years.

     The Company periodically, at least quarterly, analyzes intangible assets
for potential impairment, assessing the appropriateness of lives and
recoverability of unamortized balances through measurement of undiscounted
operating cash flows on a basis consistent with generally accepted accounting
principles.


RESEARCH AND DEVELOPMENT

     Research and development costs are expensed when incurred. Software
development costs are expensed as incurred. Such costs are required to be
expensed until the point that technological feasibility and proven marketability
of the product are established. Costs otherwise capitalized after such point
also are expensed because they are insignificant.


INCOME TAXES

     Deferred income taxes are recognized for the tax consequences in future
years of differences between the tax bases of assets and liabilities and their
financial reporting amounts at each year end based on enacted tax laws and
statutory tax rates applicable to the periods in which the differences are
expected to affect taxable income. Income tax expense is the tax payable for the
period and the change during the period in deferred tax assets and liabilities.

     Tax credits are accounted for under the flow-through method, which
recognizes the benefit in the year in which the credit is utilized.


INCOME (LOSS) PER COMMON SHARE

     Net income (loss) per share has been calculated for all periods pursuant to
the provisions of Statement of Financial Accounting Standards No. 128, which the
Company adopted in the first quarter of fiscal 1998. Basic net income (loss) per
share is calculated based on only the weighted average of common shares
outstanding during


                                                         29
                                                         DIGI INTERNATIONAL INC.
<PAGE>

the period. Net income (loss) per share, assuming dilution, is computed by
dividing net income (loss) by the weighted average number of common and common
equivalent shares outstanding. The Company's only common stock equivalents are
those that result from dilutive common stock options. The calculation of diluted
earnings per common share for 1996 includes 259,904 of such common stock
equivalents. The calculation of diluted loss per common share for 1998 and 1997
excludes 835,670 and 236,165 equivalent shares, respectively, of the Company's
common stock attributable to common stock options because their effect would be
antidilutive.


FOREIGN CURRENCY TRANSLATION

     Financial position and results of operations of the Company's 
international subsidiaries generally are measured using local currencies as 
the functional currency. Assets and liabilities of these operations are 
translated at the exchange rates in effect at each fiscal year-end. 
Statements of operations accounts are translated at the average rates of 
exchange prevailing during the year. Translation adjustments arising from the 
use of differing exchange rates from period to period are included in the 
cumulative translation account in stockholders' equity.


USE OF ESTIMATES

     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The most
significant areas which require the use of management's estimates relate to the
determination of the estimated fair value and lives of acquired in-process
research and development and other acquired intangible assets, allowances for
obsolete inventories, uncollectable accounts receivable and sales returns and
accruals for warranty costs.


NEW ACCOUNTING STANDARDS

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income." The
statement establishes standards for the reporting and display of comprehensive
income and its components. Comprehensive income is defined as the change in
equity of a business enterprise during a period from transactions and other
events and circumstances from non-owner sources. It includes all changes in
equity during a period except those resulting from investments by owners and
distributions to owners. This standard will require that an enterprise display
an amount representing total comprehensive income for the period. Statement No.
130 will be initially effective for the first quarter of the Company's fiscal
year ending September 30, 1999. Adoption of Statement of Financial Accounting
Standards No. 130 will not impact the results of operations or the financial
position of the Company.

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information," which supersedes Statement No. 14. This
statement changes the way that public business enterprises report segment
information, including financial and descriptive information about their
operating segments, in annual financial statements and would require that those
enterprises report selected segment information in interim financial reports to
stockholders. Operating segments are defined as revenue-producing components of
the enterprise which are generally used internally for evaluating segment
performance. Statement No. 131 will be effective for the Company beginning with
the first quarter of the Company's fiscal year ending September 30, 1999.
Management has not yet completed its analysis of the effects of this Statement
on its financial reporting.

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." Statement No. 133 will be effective for the Company
beginning with the Company's fiscal year ending September 30, 2000. As the
Company presently has no derivative instruments and is not involved in hedging
activity, the Company does not expect the adoption of Statement No. 133 to have
an impact on the results of operations or the financial position of the Company.

     In October 1997, Statement of Position 97-2, "Software Revenue Recognition"
(SOP 97-2), was issued. SOP 97-2 provides guidance on when revenue should be
recognized and in what amounts for licensing, selling, leasing or otherwise
marketing computer software. SOP 97-2 will become effective for the Company's
fiscal year ending September 30, 1999. The adoption of SOP 97-2 is not expected
to have a significant impact on the results of operations or financial position
of the Company.


2  >>  ACQUISITIONS

     In July 1998, the Company acquired all of the outstanding common stock of
ITK International, Inc. (ITK). The transaction was accounted for using the
purchase method of accounting. Accordingly, the purchase price was allocated to
the estimated fair value of assets acquired and liabilities assumed.

     Components of the purchase consideration, including related transaction
costs, consist of $14,767,154 in cash, the Company's common stock with a market
value of $11,671,229 and $1,276,436 of replacement stock options issued by the
Company to ITK option holders. The cash and the Company's common stock were
issued in exchange for outstanding shares of ITK's common stock and the
Company's stock options were issued in exchange for the outstanding ITK common
stock options. The value of the Company's common stock issued was based on a per
share value of approximately $20.25, which was the market value of the Company's
common


                     30
DIGI INTERNATIONAL INC.

<PAGE>

stock on the date the Company and ITK agreed to the terms of the purchase. The
value of the Company's common stock options is based on the excess of the market
value of the Company's common stock over the option exercise prices on the date
that these options were granted to ITK employees. The purchase price will
increase by $963,323 if the unvested portion of stock options granted to the ITK
employees vest. Such amount has been recorded as unearned stock compensation.

     Valuation of the intangible assets acquired was determined by an
independent appraisal company and consists of purchased in-process research and
development (IPR&D), proven technology and an assembled workforce. The purchase
price exceeded the estimated fair value of tangible and intangible assets
acquired by $7,130,253, which was recorded as goodwill.

     The table below is an analysis of the purchase price allocation.

     Management, based upon an independent appraisal, estimates that $26,000,000
of the purchase price represents the fair value of purchased IPR&D that had not
yet reached technological feasibility and has no alternative future use. The
amount allocated to IPR&D was expensed as a non-recurring, non-tax-deductible
charge upon consummation of the acquisition. The Company is using the acquired
in-process research and development in the area of Internet protocol telephony,
which will become part of the Company's product line over the next several
years.

     The identifiable intangible assets of $12,700,000 included in the purchase
price allocation set forth above are comprised of proven technology with an
appraised fair value of $11,300,000 and an assembled workforce with an appraised
fair value of $1,400,000, which have estimated useful lives of five years and
six years, respectively. The remaining unallocated purchase price represents
goodwill, which is being amortized over seven years.

     In July 1998, the Company acquired all of the outstanding common stock of
Central Data Corporation (CDC). The transaction was accounted for using the
purchase method of accounting. Accordingly, the purchase price was allocated to
the estimated fair value of assets acquired and liabilities assumed, including
estimated restructuring and integration costs of $750,000.

     Components of the purchase consideration, including related transaction
costs, consist of $14,261,965 in cash, the Company's common stock with a market
value of $4,039,475 and $891,184 of replacement stock options issued by the
Company to CDC option holders. The cash and the Company's common stock were
issued in exchange for outstanding shares of CDC's common stock and the
Company's stock options were issued in exchange for the outstanding CDC common
stock options. The value of the Company's common stock issued was based on a per
share value of approximately $20.25, which was the market value of the Company's
common stock on the date the Company and CDC agreed to the terms of the
purchase. The value of the Company's common stock options is based on the excess
of the market value of the Company's common stock over the option exercise
prices on the date that these options were granted to CDC employees. The
purchase price will increase by $1,230,683 if the unvested portion of stock
options granted to the CDC employees vest. Such amount has been recorded as
unearned stock compensation.

     Valuation of the intangible assets acquired was determined by an
independent appraisal company and consists of purchased in-process research and
development (IPR&D), proven technology and an assembled workforce. The purchase
price exceeded the estimated fair value of tangible and intangible assets
acquired by $1,034,833, which was recorded as goodwill.

     The table below is an analysis of the purchase price allocation.

3  >>  RESTRUCTURING


     In July 1998, the Company's Board of Directors approved a restructuring
plan related to the consolidation of its offices in Germany and the United
Kingdom. The restructuring plan relates to the elimination of existing
facilities rendered redundant by the acquisition of ITK. The charge of
$1,020,000 ($647,000 net of tax benefits or $0.04 per share), consisted
primarily of existing commitments for rent, contractual payments on office
equipment, write-offs of leasehold improvements and severance costs associated
with eliminating six positions. Management of the Company expects that these
restructuring activities will be completed by the end of the second quarter of
fiscal year 1999.

     In connection with the Company's acquisition of ITK, the Company has
implemented a plan of reorganization and accordingly, has recognized a
$3,484,000 restructuring liability which the Company has included as a component
of total liabilities assumed in the acquisitions. The components of the
restructuring liability are as follows:

                                                 -------------
</TABLE>

     Management of the Company expects to complete these restructuring
activities by the end of the third quarter of fiscal year 1999. No amounts of
this liability have been paid as of September 30, 1998.

     In connection with the Company's acquisition of CDC, the Company has
implemented a plan of reorganization and accordingly, the Company has recognized
a $750,000 restructuring liability which the Company has included as a component
of total liabilities assumed in the acquisition. The components of the
restructuring liability are as follows:

</TABLE>

     Management of the Company expects to complete these restructuring
activities by the end of the second quarter of fiscal year 1999. No amounts of
this liability have been paid as of September 30, 1998.

     In February 1997, the Company's Board of Directors approved a restructuring
plan that resulted in a restructuring charge of $10,471,482 ($8,283,681, net of
tax benefits or $0.62 per share). The corporate restructuring plan resulted in
consolidation and reduced costs and expenses. It included the closing of the
Cleveland manufacturing facility, the reduction of selected product lines and
the consolidation and closing of the Torrance, California and Nashville,
Tennessee research and development facilities. These costs included: (i) write
downs of the carrying values of fixed assets related to the closed manufacturing
and research and development facilities, (ii) write downs of the carrying values
of goodwill and identifiable intangible assets (primarily licensing agreements
related to the discontinued product lines) and related inventories, and (iii)
severance costs associated with the elimination of 105 positions. These
restructuring activities were completed in fiscal year 1997.

     The restructuring charge consisted of $1,259,769 in net cash expenditures
(primarily severance), of which all had been paid as of September 30, 1997, and
$9,211,713 resulting from the write-down of asset carrying values.


4  >>  RECLASSIFICATION OF CERTAIN EXPENSES


     Certain costs relating to systems support and communications costs, which
previously were included in general and administrative expenses, have been
reclassified into sales and marketing and research and development expenses for
the years September 30, 1997 and 1996. Such amounts were $2,647,207 in 1997 and,
$2,707,024 in 1996. These reclassifications had no impact on previously reported
operating income, or net income.


5  >>  INVESTMENT IN AETHERWORKS CORPORATION


     In May 1998, the Company exchanged its previously purchased $13,796,525 of
convertible notes from AetherWorks Corporation, a development stage company
engaged in the development of wireless and dial-up remote access technology, for
a non-interest bearing $8,000,000 non-convertible note. As a part of the
exchange, the Company relinquished its rights to any future technology or claims
on any of AetherWorks' intellectual properties. In exchange, the Company has
been released from all of its guarantees of certain lease obligations of
AetherWorks. As a result, the Company has


                     32
DIGI INTERNATIONAL INC.

<PAGE>

reversed its $1,350,000 accrual established in the fourth quarter of 1997, for
the estimated cost related to its guarantee of such lease obligations and has
included such amount in AetherWorks Corporation gain for the year ended
September 30, 1998.

     Due to the significant uncertainty as to its collectibility, the $8,000,000
note, which matures in 2001, has been recorded by the Company as having no
carrying value.

     The Company continues to lease to AetherWorks $1,325,000 of computer
equipment under a three-year direct financing lease, expiring in 2000.

     For the years 1997 and 1996, the Company has reported its investment in
AetherWorks on the equity method and reported net losses of $5,764,201 and
$3,623,776, respectively. These losses, which exclude $5,758,548 of additional
charges accrued as of September 30, 1997 as described below, represent 100% of
AetherWorks net losses for the two years. The percentage of AetherWorks net
losses included in the Company's Statement of Operations was based upon the
percentage of financial support provided by the Company (versus other investors)
to AetherWorks during such years.

     Because of the significant uncertainty of the future of AetherWorks
Corporation, as demonstrated by its lack of ability to generate positive cash
flow, obtain other sources of equity financing and its continued uncertainty in
developing commercially marketable products, the Company decided, as of
September 30, 1997, to write off its remaining investment of $2,408,548 in
AetherWorks, and to accrue and expense its remaining obligation to purchase
$2,000,000 of additional notes. In addition, the Company also accrued $1,350,000
for its obligation resulting from its guarantees of certain AetherWorks' lease
obligations as of September 30, 1997.

     The following represents condensed financial information from the audited
statements of AetherWorks for the years ended September 30, 1997 and 1996:

10  >>  STOCK OPTIONS AND EMPLOYEE STOCK PURCHASE PLAN


     The Company's stock option plan (the Stock Option Plan) provides for the
issuance of nonstatutory stock options and incentive stock options (ISOs) to key
employees and nonemployee board members holding less than 5% of the outstanding
shares of the Company's common stock. The Company's Non-Officer Stock Option
Plan (the Non-Officer Plan and, together with the Stock Option Plan, the Plans),
provides for the issuance of nonstatutory stock options to key employees who are
not officers or directors of the Company.


                     34
DIGI INTERNATIONAL INC.

<PAGE>

     The option price for ISOs and non-employee directors options granted under
the Stock Option Plan is set at the fair market value of the Company's common
stock on the date of grant. The option price for nonstatutory options granted
under the Plans is set by the Compensation Committee of the Board of Directors.
The authority to grant options under the Plans and set other terms and
conditions rests with the Compensation Committee. The Stock Option Plan
terminates in 2006. The Non-Officer Plan does not have a designated termination
date.

     During the years ended September 30, 1998, 1997, and 1996, 287,882, 50,106,
and 114,192 shares of the Company's Common Stock, respectively, were issued upon
the exercise of options for 289,353, 50,167, and 123,959 shares, respectively.
The difference between shares issued and options exercised results from the
provision in the Plans allowing employees to elect to pay their withholding
obligation through share reduction. Withholding taxes paid by the Company as a
result of the share withholding provision amounted to $28,871 in 1998, $5,171 in
1997, and $186,927 in 1996.

     During the year ended September 30, 1998 the Board of Directors authorized
the issuance of incentive stock options for the purchase of 486,631 shares. In
addition, the Board of Directors authorized the issuance of nonstatutory stock
options for the purchase of 543,461 shares, at prices below the market value of
the stock on the grant dates.

     During the year ended September 30, 1997 the Board of Directors authorized
the cancellation and reissue of nonstatutory stock options to certain employees
for the purchase of 823,326 shares, at an exercise price below the market value
of the stock. Under this authorization, the original option issues were canceled
and new options were issued with a new four-year vesting schedule. During the
year ended September 30, 1996, the Board of Directors authorized the issuance of
nonstatutory stock options for the purchase of 2,500 shares at prices below the
market value of the stock on the grant date.

     The difference between the option price and market value at the date of
grant for the above option arrangements has been recorded as additional paid-in
capital with an offsetting debit within stockholders' equity to unearned stock
compensation. The compensation expense related to these option grants is
amortized to operations over the contractual vesting period in which employees
perform services and amounted to $1,012,440 in 1998, $244,569 in 1997, and
$204,793 in 1996.

     Stock options and common shares reserved for grant under the Plans are as

     Commencing April 1996, the Company has sponsored an Employee Stock Purchase
Plan (the Purchase Plan) which covers all domestic employees with at least 90
days of service. The Purchase Plan allows eligible participants the right to
purchase common stock on a quarterly basis at the lower of 85% of the market
price at the beginning or end of each three-month offering period. Employee
contributions to the plan were $658,118 in 1998, $534,327 in 1997, and $200,888
in 1996. Pursuant to the Purchase Plan, 37,398, 69,402, and 8,835 shares were
issued to employees during the fiscal years ended 1998, 1997 and 1996,
respectively. As of September 30, 1998, 384,365 shares are available for future
issuances under the Purchase Plan.


11  >>  STOCK-BASED COMPENSATION


     In accordance with Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" (SFAS 123), the Company has chosen to
continue to account for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," and related interpretations. Accordingly,
compensation costs for stock options granted to employees are measured as the
excess, if any, of the fair value of the Company's stock at the date of the
grant over the amount an employee must pay to acquire the stock. Such
compensation costs, if any, are amortized on a straight-line basis over the
option vesting schedule.

  Had the Company used the fair-value-based method of accounting for its stock
options granted in 1998, 1997 and 1996, and charged operations over the option
vesting periods based on the fair value of options at the date of grant, net
(loss) income and net (loss) income per common share would have been changed to
the following pro forma amounts:

exercisable only if certain ownership considerations are met. The Company will
be entitled to redeem the rights prior to the rights becoming exercisable.

17  >>  FOURTH QUARTER INFORMATION


     A provision for inventory obsolescence of $1.9 million was recorded during
the three-month period ended June 30, 1998. This provision was reversed during
the three-month period ended September 30, 1998.


18  >>  CONTINGENCIES


     During fiscal 1997, the Company and certain of its previous officers were
named as defendants in a series of putative securities class action lawsuits in
the United States District Court for the District of Minnesota on behalf of an
alleged class of purchasers of its common stock during the period January 25,
1996 through December 23, 1996, inclusive, which were consolidated, through
a Consolidated Amended Complaint filed in May 1997. Also in 1997, a similar but
separate action was filed by the Louisiana State Employees Retirement System.
The Consolidated Amended Complaint and the Louisiana Amended Complaint allege
the Company and certain of its previous officers violated federal securities
laws by, among other things, misrepresenting and/or omitting material
information concerning the Company's operations and financial results. The
Louisiana Amended Complaint also alleges misrepresentations in violation of
state common law.

     In a decision issued on May 22, 1998, the District Court granted in part
and denied in part the motions of the Company and its three former officers to
dismiss the Consolidated Amended Complaint and the Louisiana Amended Complaint.
The Court dismissed without leave to replead all claims asserted in both cases,
except for certain federal securities law claims based upon alleged
misrepresentations and/or omissions relating to the accounting treatment applied
to the Company's AetherWorks investment. The Court also limited the claims
asserted in the Louisiana Amended Complaint to the 11,000 shares of the
Company's stock held subsequent to November 14, 1996. These claims remain
pending against the Company and two of its former officers, Ervin F. Kamm, Jr.
and Gerald A. Wall. Discovery in the actions is proceeding.

     Because the lawsuits are in preliminary stages, the ultimate outcomes
cannot be determined at this time, and no potential assessment of the probable
or possible effects of such litigation, if any, on the Company's financial
position, liquidity or future operations can be made.

     In the normal course of business, the Company is subject to various claims
and litigation. Management of the Company expects that these various litigation
items will not have a material adverse effect on the results of operations or
financial condition of the Company.

     The Company maintains a system of internal controls designed to provide
reasonable assurance that assets are safeguarded, transactions are properly
executed in accordance with management's authorization, and accounting records
may be relied upon for the preparation of financial statements and other
?nancial information. The system is monitored by direct management review.
Limitations exist in any system of internal control, based upon the recognition

REPORT OF INDEPENDENT ACCOUNTANTS  >>


TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF DIGI INTERNATIONAL INC.

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, cash flows and stockholders'
equity present fairly, in all material respects, the financial position of Digi
International Inc. and subsidiaries (the Company), at September 30, 1998 and
1997 and the results of their operations and their cash flows for the years then
ended in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above. As discussed in Note 5, the Company has recorded its investment in
AetherWorks Corporation (AetherWorks) on the equity method; the 1997 and 1996
consolidated statements of operations include AetherWorks' net operating losses
for the years ended September 30, 1997 and 1996 of $5,764,201 and $3,623,776,
respectively. We did not audit the financial statements of AetherWorks, which
statements were audited by other auditors whose report has been furnished to us,
and our opinion, insofar as it relates to the amounts included for AetherWorks'
net operating losses, is based solely on the report of other auditors.
