                             INTERFACE SYSTEMS, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  BASIS OF PRESENTATION

The interim consolidated financial statements of Interface Systems, Inc. have
been prepared by the Company without audit pursuant to the rules and regulations
of the Securities and Exchange Commission. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations. The information included in this report
should be read in conjunction with the financial statements for the year ended
September 30, 1997 and notes thereto included in the Company's Annual Report on
Form 10-K.

In the opinion of management, the accompanying interim consolidated financial
statements reflect all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the Company's financial
position, results of operations and cash flows for the periods presented. The
results for the quarter ended March 31, 1998 are not necessarily indicative of
the results to be expected for any future period or for the entire year.

Certain prior year amounts have been reclassified to conform to the 1998
financial statement presentation. As more thoroughly discussed in Note 2,
Interface Systems International, Ltd. ("ISIL") is presented as a discontinued
operation for all periods presented.

2.    SALE OF INTERFACE SYSTEMS INTERNATIONAL LTD. DISTRIBUTION BUSINESS;
      DISCONTINUED OPERATIONS

In May 1998, the Company consummated a sale of substantially all assets and
certain liabilities of the distribution business of ISIL to Fayrewood plc, a
U.K. company quoted on the Alternative Investment Market of the London Stock
Exchange. The sale did not include the assumption by Fayrewood of all of ISIL's
liabilities, and therefore, no assurances can be given that claims will not be
made against the Company in the future arising out of ISIL's former operations.
Such claims could have a material adverse effect on the Company's financial
condition and results of operations.

The consideration of $3.6 million is approximately equal to 83% of the net
assets sold and is subject to audit. The net assets sold, estimated at $4.3
million, consist of accounts receivable (exclusive of certain aged receivables),
inventory and fixed assets, net of accounts payable. The consideration is
payable in cash with an initial payment of $2.9 million and the balance of the
consideration due in approximately 60 days upon completion of an audit of the
net assets sold. The Company recorded a charge of approximately $1.8 million in
the quarter ended March 31, 1998 for the loss on sale and related expenses.

Accordingly, the operating results of ISIL have been segregated from continuing
operations and reported as a separate line item on the Company's consolidated
statement of operations. In addition, the assets and liabilities of ISIL,
excluding its note payable, have been reclassified on the Company's consolidated
balance sheets and reported as assets and liabilities of the discontinued
operation. The Company has restated its prior financial statements to present
the operating results of ISIL as a discontinued operation.

3.  BORROWINGS

The Company has bank credit facilities which provide for aggregate borrowings of
up to $11.5 million. As of March 31, 1998, $7.6 million was outstanding under
these facilities. Advances under these facilities bear interest at the bank's
prime rate (8.5% at March 31, 1998) plus 1%, are payable on demand and are
collateralized by substantially all of the Company's assets. The credit facility
covering $3.5 million of the aggregate borrowings expires February 28, 1999 and
the facility covering the balance of the borrowings is subject to review on
August 28, 1998. The amount available for borrowing at any one time under the
facilities is based on borrowing base formulas relating to levels of accounts
receivable, inventories and other bank covenants. Under such formulas,
approximately $1.4 million was available to the Company as of March 31, 1998.

Under the terms of the agreements, the Company is required to maintain certain
minimum working capital, net worth and profitability levels and other specific
financial ratios. The Company was in violation of the minimum net worth covenant
of the credit facilities at March 31, 1998. The Bank waived the default through
an amendment to the facilities. In addition, the agreements prohibit the payment
of cash dividends and contain certain restrictions on the Company's ability to
borrow money or purchase assets or interests in other entities without the prior
written consent of the bank.

4.   EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share." The Company
adopted the new standard for the quarter ended December 31, 1997, as required by
the statement. The implementation of this standard had no effect on the
consolidated financial statements for the periods presented.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
          RESULTS OF OPERATIONS

SALE OF INTERFACE SYSTEMS INTERNATIONAL LTD. DISTRIBUTION BUSINESS;  
DISCONTINUED OPERATIONS

In May 1998, the Company consummated a sale of substantially all assets and
certain liabilities of the distribution business of ISIL to Fayrewood plc, a
U.K. company quoted on the Alternative Investment Market of the London Stock
Exchange. The sale did not include the assumption by Fayrewood of all of ISIL's
liabilities, and therefore, no assurances can be given that claims will not be
made against the Company in the future arising out of ISIL's former operations.
Such claims could have a material adverse effect on the Company's financial
condition and results of operations.

The consideration of $3.6 million is approximately equal to 83% of the net
assets sold and is subject to audit. The net assets sold, estimated at $4.3
million, consist of accounts receivable (exclusive of certain aged receivables),
inventory and fixed assets, net of accounts payable. The consideration is
payable in cash with an initial payment of $2.9 million and the balance of the
consideration due in approximately 60 days upon completion of an audit of the
net assets sold. The Company recorded a charge of approximately $1.8 million in
the quarter ended March 31, 1998 for the loss on sale and related expenses.

Accordingly, the operating results of ISIL have been segregated from continuing
operations and reported as a separate line item on the Company's consolidated
statement of operations. In addition, the assets and liabilities of ISIL,
excluding its note payable, have been reclassified on the Company's consolidated
balance sheets and reported as assets and liabilities of the discontinued
operation. The Company has restated its prior financial statements to present
the operating results of ISIL as a discontinued operation.

RESULTS OF OPERATIONS

Net Revenues. Revenues for the second quarter ended March 31, 1998 were $5.1
million, an increase of 4.2% over revenues of $4.9 million for the second
quarter of fiscal 1997. The increase was due primarily to increased sales of
Oasis Document Server software and related consulting and integration services.
Revenues for the first six months of fiscal 1998 were $10.7 million, an increase
of 18.4% over revenues of $9.0 million for the same period of fiscal 1997. The
increase for the six month period was primarily due to increased sales of
Enterprise Network products as well as increased sales of Oasis products offset
by decreased sales of printer products.

Cost of Revenues. Cost of revenues were $2.3 million and $4.5 million, or 46.1%
and 92.6% of net revenues for the quarters ended March 31, 1998 and 1997,
respectively; and $4.7 million and $7.2 million, or 44.2% and 79.9% of net
revenues for the six months ended March 31, 1998 and 1997, respectively. Cost of
revenues decreased as a percentage of net revenues due primarily to write-offs
in the second quarter of fiscal 1997 of $1.8 million related to printer business
inventory and capitalized software development costs. Additionally, the decrease
resulted from higher sales of core business software products, which have higher
gross profit margins. Cost of revenues included amortization of capitalized
software development costs of $353,000 and $470,000 for the quarters ended March
31, 1998 and 1997, respectively, and $708,000 and $1,011,000 for the six months
ended March 31, 1998 and 1997, respectively. In the future, amortization of
capitalized software development costs is expected to be less than $50,000 per
quarter.

Product Development Costs. Product development costs were $944,000 and $626,000,
or 18.6% and 12.9% of net revenues for the quarters ended March 31, 1998 and
1997, respectively; and $1,848,000 and $1,128,000, or 17.3% and 12.5% of net
revenues for the six months ended March 31, 1998 and 1997, respectively. The
absolute dollar increase for both periods primarily reflects a decrease of
$420,000 and $1,087,000 in the amount of expense deferred through capitalization
of internally developed software for the quarter and six months ended March 31,
1998, respectively, as compared with the same periods of fiscal 1997.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses were $1.9 million and $2.1 million, or 37.3% and 43.3%
of net revenues for the quarters ended March 31, 1998 and 1997, respectively;
and were $4.1 million and $4.1 million, or 38.1% and 45.3% of net revenues for
the six months ended March 31, 1998 and 1997, respectively. The absolute dollar
decrease for the second quarter was primarily due to a reduction in the
Company's core business sales force in the United Kingdom offset by an increase
in marketing expenses to promote sales of Oasis Document Server software and
related consulting and integration services.

Income Taxes. The income tax benefit for the quarter and six months ended March
31, 1998 results from the utilization of net operating losses and other tax
attributes.

LIQUIDITY AND CAPITAL RESOURCES

At March 31, 1998, the Company's primary sources of liquidity included cash and
cash equivalents of $1.0 million and short-term credit facilities with a bank
providing for $11.5 million of borrowings, of which approximately $1.4 million
was available.

For the six months ended March 31, 1998, net cash of $1.4 million was provided
by operating activities compared to net cash of $ 2.2 million used in operating
activities for the same period of fiscal 1997. Cash was provided by operating
activities for the first six months of fiscal 1998 primarily due to increased
accounts payable, decreased inventory and non-cash charges partially off-set by
increased accounts receivable and net loss for the period. Net cash used in
financing activities was $1.1 million for the first six months of fiscal 1998
due primarily to a reduction in notes payable.

The Company has bank credit facilities which provide for aggregate borrowings of
up to $11.5 million. As of March 31, 1998, $7.6 million was outstanding under
these facilities. The borrowings are used primarily by ISIL in the operation of
its distribution business. Advances under these facilities bear interest at the
bank's prime rate plus 1%, are payable on demand and are collateralized by
substantially all of the Company's assets. The credit facility covering $3.5
million of the borrowings expires February 28, 1999 and the facility covering
the balance of the borrowings is subject to review on August 28, 1998.

Under the terms of the agreements, the Company is required to maintain certain
minimum working capital, net worth and profitability levels and other specific
financial ratios. The Company was in violation of the minimum net worth covenant
of the credit facilities at March 31, 1998. The Bank waived the default through
an amendment to the facilities. In addition, the agreements prohibit the payment
of cash dividends and contain certain restrictions on the Company's ability to
borrow money or purchase assets or interests in other entities without the prior
written consent of the bank.

The Company believes that its existing cash balances, available credit
facilities and future operating cash flows will be sufficient for near term
operating needs. The Company believes it will renew the bank credit facilities
prior to expiration of the facilities. The foregoing statements are "forward
looking statements" within the meaning of the Securities Exchange Act of 1934.
The extent to which such sources will be sufficient to meet the Company's
anticipated cash requirements is subject to a number of uncertainties including
the ability of the Company's operations to generate sufficient cash to support
operations, and other uncertainties described in "Management's Discussion and
Analysis of Results of Operations - Uncertainties Relating to Forward-Looking
Statements."

"Management's Discussion and Analysis of Results of Operations" contains
"forward-looking statements" within the meaning of the Securities Exchange Act
of 1934, as amended, based on current management expectations. Actual results
could differ materially from those in the forward-looking statements due to a
number of uncertainties, including, but not limited to: general economic
conditions particularly related to demand for the Company's products and
services, changes in Company strategy, product life cycles, competitive factors
(including the introduction or enhancement of competitive products), pricing
pressures, the results of the audit of the ISIL net assets sold, component price
increases, delays in introduction of planned hardware and software products,
software defects and latent technological deficiencies in new products, changes
in operating expenses, inability to attract or retain sales and/or engineering
talent, changes in customer requirements and evolving industry standards.
