              UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS

The following unaudited pro forma condensed financial statements give effect to
the acquisition of ITK International, Inc. ("ITK") by Digi International, Inc.
(the "Company") using the purchase method of accounting.  These unaudited pro
forma condensed financial statements are presented for illustrative purposes
only and are not necessarily indicative of the combined financial position or
results of operations for future periods or the results that actually would have
been realized had the Company and ITK been a combined company during the
specified periods.  The pro forma condensed financial statements, including the
notes thereto, are qualified in their entirety and should be read in conjunction
with the historical consolidated financial statements of the Company and ITK.

The unaudited pro forma condensed financial statements are based on the
respective historical consolidated financial statements and the notes thereto of
the Company and ITK.  The purchase price was allocated to the estimated fair
value of assets acquired and liabilities assumed.  The preliminary purchase
price allocation is based on the Company's estimates of fair value.  The Company
is awaiting additional information related to the fair value of certain assets
acquired and liabilities assumed.  However, management does not expect the
finalization of the allocation of its purchase price to the assets acquired and
liabilities assumed of ITK will have a material effect on the purchase price
allocation.

NOTES TO UNAUDITED PRO FORMA CONDENSED BALANCE SHEET
(DOLLARS IN THOUSANDS)


     1.   FINANCIAL STATEMENTS:

     Digi International Inc. (the "Company") has a September 30 fiscal year end.
     The unaudited historical balance sheet information of the Company as of
     June 30, 1998 was derived from the unaudited consolidated condensed
     financial statements of the Company which are included in the Company's
     report on Form 10-Q for the quarter ended June 30, 1998.  Prior to its
     acquisition by the Company, ITK International Inc. ("ITK") had a June 30
     fiscal year-end.  The unaudited historical consolidated balance sheet
     information of ITK as of June 30, 1998 was derived from the consolidated
     financial statements of ITK included elsewhere in this Form 8-K/A.  The pro
     forma condensed balance sheet assumes the business combination took place
     on June 30, 1998.


     2.   UNAUDITED PRO FORMA CONDENSED BALANCE SHEET ADJUSTMENTS:

     The purchase price was allocated to the estimated fair value of assets
     acquired and liabilities assumed.  The pro forma adjustments presented are
     as of June 30, 1998.  The Company is awaiting additional information
     related to the fair value of certain assets acquired and liabilities
     assumed.  However, management does not expect the finalization of the
     allocation of its purchase price to the assets acquired and liabilities
     assumed of ITK will have a material effect on the purchase price
     allocation.

     (a)  Adjustment reflects the components of the purchase consideration 
          and related transaction costs, which included $14,434 in cash, the 
          Company's common stock with a market value of $11,671 and $1,276 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 is 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 if the 
          unvested portion of stock options granted to the ITK employees 
          vest.  Such amount has been recorded as unearned stock compensation 
          in the stockholders' equity section of the unaudited pro forma 
          condensed balance sheet as of June 30, 1998.

     (b)  Adjustment reflects the elimination of ITK's historical stockholders'
          equity.

     (c)  Adjustment reflects the elimination of note payable to the Company
          from ITK resulting from funds advanced to ITK during June 1998.

     (d)  Adjustment reflects portion of purchase price allocated to
          identifiable intangible assets, including purchased in-process
          research and development.  Valuation of the intangible assets acquired
          was conducted by an independent third-party appraisal company and
          consists of purchased in-process research and development, proven
          technology and an assembled workforce.  The purchase price exceeded
          the estimated fair value of tangible assets acquired and liabilities
          assumed by approximately $41,099.  This excess purchase price was
          allocated to purchased in-process research and development,
          identifiable intangible assets and goodwill, including certain
          existing identifiable intangible assets and goodwill of ITK as of 
          June 30, 1998. 

     The table below is a summary of the preliminary amounts allocated to
purchased in-process research and development, identifiable intangible assets
and goodwill.


                                                                     
          Cash and fair value of the Company's common stock and common
             stock options issued                                       $26,276
          Direct acquisition costs                                        1,105

          Estimated fair value of tangible assets acquired 
             (approximates recorded book value)                          22,252

          Purchase price in excess of estimated fair value of tangible 
             assets acquired                                            $41,099

          Estimated fair value of in-process research and development,
             identifiable intangible assets and goodwill:
             In-process research and development                         26,000
             Identifiable intangible assets                              12,700
             Goodwill                                                     2,399

                                                                        $41,099


     Management estimates that $26,000 of the purchase price represents the fair
value of purchased in-process research and development that has not yet reached
technological feasibility and has no alternative future use.  This amount was
expensed as a non-recurring, non-tax-deductible charge upon consummation of the
acquisition.  This amount has been reflected as a reduction in stockholders'
equity and has not been included in the pro forma condensed statements of
operations due to its non-recurring nature.

     2.   UNAUDITED PRO FORMA CONDENSED BALANCE SHEET ADJUSTMENTS, CONTINUED:

          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 that the initial Internet
          Protocol Telephony products 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
          relate 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
          in the aggregate through the year 2007, consisting of $300 in 1998;
          $2,000 in 1999; $4,800 in 2000; $4,800 in 2001; $4,300 in 2002; $3,200
          in 2003; $2,500 in 2004; $1,400 in 2005; $900 in 2006 and $600 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.

     2.   UNAUDITED PRO FORMA CONDENSED  BALANCE SHEET ADJUSTMENTS, CONTINUED:

          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 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 2000.

     The identifiable intangible assets of $12,700 included in the purchase
     price allocation set forth above are comprised of proven technology with an
     appraised fair value of 

     $11,300, and an assembled workforce with an appraised fair value of $1,400,
     which have estimated useful lives of five years and six years,
     respectively.

DIGI INTERNATIONAL INC.
NOTES TO UNAUDITED PRO FORMA CONDENSED STATEMENT OF OPERATIONS
(DOLLARS IN THOUSANDS)



     1.   FINANCIAL STATEMENTS:

     Digi International Inc. (the Company) has a September 30 fiscal year-end. 
     The unaudited historical statement of operations information of the Company
     for the year ended September 30, 1997 was derived from the consolidated
     financial statements of the Company, which are included in the Company's
     annual report on Form 10-K for the year ended September 30, 1997.  The
     historical statement of operations information of the Company for the 
     nine-month periods ended June 30, 1998 and 1997 was derived from the 
     condensed financial statements of the Company which are included in the 
     Company's reports on Form 10-Q for the quarters ended June 30, 1997 and 
     1998.

     Prior to the acquisition by the Company, ITK International Inc. (ITK) had a
     June 30 fiscal year-end.  Accordingly, the ITK statement of operations
     information for the twelve-month period ended September 30, 1997 and the
     nine-month periods ended June 30, 1998 and 1997 has been derived by
     combining ITK's unaudited consolidated results of operations for the
     applicable calendar quarters.

     The pro forma condensed statements of operations assume the business
     combination took place as of the beginning of the periods presented.  The
     pro forma condensed statement of operations for the twelve-month period
     ended September 30, 1997 combines the Company's consolidated statement of
     operations and ITK's consolidated statement of operations for the 
     twelve-month period then ended.  The pro forma condensed statements of 
     operations for the nine-month periods ended June 30, 1998 and 1997 combine
     the Company's unaudited consolidated statement of operations and ITK's
     unaudited consolidated statement of operations for the nine-month periods
     ended June 30, 1998 and 1997, respectively.  On a combined basis there were
     no material transactions between the Company and ITK during the periods
     presented.

     The pro forma combined provision for income taxes may not necessarily be
     indicative of amounts that would have resulted had the Company and ITK
     filed consolidated income tax returns during the periods presented.


     2.   UNAUDITED PRO FORMA CONDENSED STATEMENT OF OPERATIONS ADJUSTMENTS:

     The purchase price was allocated based upon the estimated fair value of
     assets acquired and liabilities assumed.  The preliminary purchase price
     allocation is based on the Company's estimates of fair value.  The Company
     is awaiting additional information related to the fair value of certain
     assets acquired and liabilities assumed.  However, management does not
     expect the finalization of the allocation of its purchase price to the
     assets acquired and liabilities assumed of ITK will have a material effect
     on the purchase price allocation.

     2.   UNAUDITED PRO FORMA CONDENSED STATEMENT OF OPERATIONS ADJUSTMENTS,
     CONTINUED:

     (a)  Adjustment reflects amortization of acquired identifiable intangible
          assets and goodwill.  Identifiable intangible assets of $12,700 are
          comprised of proven technology with an appraised value of $11,300, and
          an assembled workforce with an appraised value of $1,400 which have
          estimated useful lives of five years and six years, respectively.  The
          estimated annual non-tax-deductible amortization charge related to the
          proven technology and workforce is approximately $2,493.  The
          estimated annual non-tax-deductible amortization charge related to
          amortization of the $2,399 allocated to goodwill, which has an
          estimated useful life of seven years, is approximately $343.

     (b)  Adjustment reflects the decrease in interest income and related tax
          effect resulting from the use of cash and cash equivalents to complete
          the acquisition.  The assumed rate of return on the cash balance was
          5%.

     (c)  Adjustment reflects the portion of Digi's income tax provision which
          would not have been recognized due to ITK's U.S. net operating losses
          for the nine-moth period ended June 30, 1998.

     (d)  Adjustment reflects net increase (decrease) in weighted average common
          shares and common equivalent shares outstanding for common stock and
          common stock options issued in connection with the acquisition, as
          well as equivalent shares of the Company that have an antidilutive
          effect on pro forma diluted earnings per common share.

            Pro forma basic earnings per common share for the periods presented
            were calculated assuming that the 576,357 shares of the Company's
            common stock issued in connection with the acquisition were issued 
            at the beginning of the periods presented.

            The calculation of pro forma diluted earnings per common share
            excludes the 71,904 equivalent shares of the Company attributable to
            the common stock options issued by the Company in connection with 
            the acquisition, to replace existing ITK common stock options.  Such
            equivalent shares were excluded in determining the weighted average
            equivalent shares outstanding for the year ended September 30, 1997
            and the nine-month period ended June 30, 1997, because their effect
            was antidilutive.
