                             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, 1999 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 December 31, 1999 may not be indicative of the
results to be expected for future quarters or the fiscal year ending September
30, 2000.

For comparative purposes, certain amounts reported in prior years' financial
statements have been reclassified to conform to current year presentations.

2.  Line-of-Credit and Notes Payable

The Company has a $3.5 million bank credit facility that matures on February 28,
2000. As of December 31, 1999, there were no borrowings outstanding under this
facility. Advances bear interest at the bank's prime rate (8.5% at December 31,
1999) plus 1%, are payable on demand and are collateralized by substantially all
of the Company's assets. The amount available for borrowing at any time is based
on borrowing base formulas relating to net worth and other bank covenants.
Under such formulas, $2.6 million was available to the Company as of December
31, 1999.

Under the terms of the credit agreement, the Company is required to maintain
certain minimum working capital, net worth and profitability levels and other
specific financial ratios. In addition, the credit agreement prohibits the
payment of cash dividends and contains 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. As of December 31, 1999, the
Company was in compliance with the bank covenants.

3.  Impact of Recently Issued Accounting Standards

The Financial Accounting Standards Board has issued SFAS No. 133 "Accounting for
Derivative Instruments and Hedging Activities." The Company is required to adopt
the provisions of SFAS No. 133 in its current fiscal year. The Company expects
the adoption will not affect results of operations or financial statements.

Effective October 1, 1998, the Company has adopted SFAS No. 130, "Reporting
Comprehensive Income", which established standards for reporting and display of
comprehensive income and its components in a full set

                                       6

of financial statements. Comprehensive income is the total of net income and all
other non-owner changes in equity. The components of comprehensive income, are
as follows:

4.   Sale of Subsidiary

On December 22, 1999, the Company completed its sale of all of the assets of it
subsidiary, I.G.K. Industries, Inc. ("IGK") to The Lance Field Company.  In
connection with the transaction, the Company transferred all of the assets of
IGK used in the manufacture and sale of custom printed circuit boards to
Lance Field.  Also in connection with the transaction, the Company transferred
the real property owned by it and located at 7232 Jackson Road, Ann Arbor,
Michigan, to L&D Capital Holdings, L.L.C., an affiliate of Lance Field
Company.  Lance Field Company also agreed to assume all current liabilities of
IGK.

Pursuant to the Asset Purchase Agreement, the aggregate purchase price for the
transaction was $1,450,000, of which $1,100,000 was paid to IGK on December 22,
1999.  The balance of the purchase price is to be paid in accordance with the
terms of a promissory note providing for the payment of $350,000.

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

OPERATIONS

The Company is currently completing a transition plan that is focused on the
movement from the manufacturing of hardware (printers, circuit boards, and
peripheral equipment) to the development and marketing of higher margin and
higher growth software solutions. The progress related to the plan is evidenced
by the current structure of the Company. Currently, the Company is organized
around two software solutions groups: L2i(TM)(Legacy-to-Internet) and Cleo.

RESULTS OF OPERATIONS

Net Revenues. Revenues for the first quarter ended December 31, 1999 were $3.4
million, a decrease of 34.4% when compared with revenues of $5.2 million for the
first quarter of fiscal 1999. The decrease was due primarily to the planned
curtailment of the printer business coupled with the decreased sales of the
Company's Cleo Enterprise Networking products, which are impacted by large
corporate orders, partially offset by the increased sales of the L2i solutions;
MyCopy(TM) and e-Bill Bridge(TM).

Cost of Revenues. Cost of revenues were $1.4 million and $2.1 million or 40.0%
and 40.3% of net revenues for the quarters ended December 31, 1999 and 1998,
respectively. The decrease for the first quarter of fiscal 2000 resulted from a
decline in sales as well as a change in the composition of sales from lower
margin hardware products to the more profitable software solutions and
consulting services.

Product Development Costs. Product development costs were $685,000 and $404,000,
or 20.0% and 7.8% of net revenues for the quarters ended December 31, 1999 and
1998, respectively. The increase was primarily due to the investment the Company
is making with respect to enhancements of its L2i software solutions.

                                       7


   8

Selling, General, and Administrative Expenses. Selling, general, and
administrative expenses were $2.9 million and $2.6 million, or 84.2% and 50.2%
of net revenues for the quarters ended December 31, 1999 and 1998, respectively.
The increase was primarily due to the addition of sales and marketing personnel
located at the Company's headquarters facility and the East Coast.

Interest and Other Income. Interest and other income for the quarter ended
December 31, 1999 was mainly composed of the $37,000 gain on sale of
substantially all assets of IGK Industries, Inc.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1999, the Company's primary sources of liquidity included cash
and cash equivalents of $1.8 million and a short-term credit facility with a
bank providing for $3.5 million of borrowings, of which $2.6 million was
available.

Cash provided by investing activities was $918,000 in the first quarter of
fiscal 2000 primarily due to the proceeds received from the sale of IGK.

The Company has a $3.5 million bank credit facility that expires on February 28,
2000. As of December 31, 1999, there were no borrowings outstanding under this
facility. Advances bear interest at the bank's prime rate (8.5% at December 31,
1999) plus 1%, are payable on demand and are collateralized by substantially all
of the Company's assets. The amount available for borrowing at any time is based
on borrowing base formulas relating to net worth and other bank covenants. Under
such formulas, $2.6 million was available to the Company as of December 31,
1999.

Under the terms of the credit agreement, the Company is required to maintain
certain minimum working capital, net worth and profitability levels and other
specific financial ratios. In addition, the credit agreement prohibits the
payment of cash dividends and contains 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. As of December 31, 1999, the
Company was in compliance with the bank covenants.

The Company believes that its existing cash balances, available credit facility
and future operating cash flows will be sufficient for near term operating
needs. The Company believes it will renew its bank credit facility prior to
expiration of the facility. 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 Financial Condition and Results of Operations - Uncertainties
Relating to Forward-Looking Statements."


YEAR 2000

The "year 2000" problem is a flaw in certain computer hardware and software
resulting from the use of 2-digit date formats. Throughout 1997, 1998 and 1999,
the Company has been addressing the risks associated with its information
technology ("IT") and non-information technology ("non-IT") systems and the
external systems of its customers, suppliers

                                       8


   9
financial organizations, utilities providers and government entities
(collectively, "Third Parties") on which the Company relies.

The Company used both internal and external resources to (a) assess the
Company's state of readiness (including the readiness of Third Parties with
which the Company interacts) with respect to the year 2000 problem; (b) estimate
the cost to correct and/or replace non-compliant internal IT and non-IT systems;
(c) assess the known risks and consequences related to failure to correct any
year 2000 problems identified; and (d) develop a contingency plan, if advisable,
to address the Company's year 2000 exposure. The Company's Board of Directors
established a committee to review the Company's efforts to address its year 2000
issues and report back to the Board at each Board meeting.

The Company tested all current versions of its products to determine whether
such products are year 2000 compliant. The Company believes that all of its
current products are year 2000 compliant. Earlier versions of the Company's
products were classified as either (a) known to be year 2000 compliant, (b)
known to not be year 2000 compliant, or (c) not tested for year 2000 compliance.
The Company did not make earlier versions of its products year 2000 compliant
and, in cases where the end user of a non-compliant product was known, made
attempts to contact the customer. In cases where the product had been sold
through a reseller, the end user is not known and therefore, cannot be
contacted. The Company completed the assessment of its principal internal IT
software systems and its personal computer and network hardware and software for
year 2000 compliance and experienced no significant year 2000 related problems.


If any of the Company's customers were unable to make their IT systems year 2000
compliant in a timely fashion, they may suspend further product purchases from
the Company. Because most of the Company's customers are Fortune 1000 companies
and banking and financial institutions, the Company expected most of its
customers to become year 2000 compliant in a timely fashion, although the
Company did not monitor their progress. All of the Company's critical vendors
were queried as to their year 2000 preparedness. For the few that did not
respond satisfactorily, alternative sources were put in place. The Company is
not aware of any significant year 2000 related problems involving its customers
or its vendors.

The Company incurred costs of approximately $200,000, most of which occurred in
the 1999 and 1998 fiscal years, to address year 2000 compliance issues. Such
costs consisted primarily of the cost of replacing non-compliant internal IT
system software and upgrading or replacing non-compliant personal computer and
network hardware and software, but do not include internal staff costs, which
the Company has not separately tracked. The Company would have incurred many of
the costs for these efforts in any event because of the normal process of
internal IT system upgrades.

While the Company believes that its efforts to address year 2000 issues for
which it is responsible have been successful, a description of its most
reasonably likely worse case year 2000 scenarios have been described above. In
addition, it is possible that there will be undetected errors or defects
associated with year 2000 in the Company's current products and internal systems
or those of its principal vendors. Although the Company does not believe that it
has any obligation to make prior versions of its

                                       9
   10

products year 2000 compliant, it is possible that its customers may take a
contrary position and initiate litigation. Because of the relative lack of
litigation concerning the year 2000 issue, it is uncertain how the Company may
be affected by such issues. In the event of litigation or one or more of the
worst case year 2000 scenarios described above, the Company's financial
condition and results of operation could be materially adversely affected.

UNCERTAINTIES RELATING TO FORWARD-LOOKING STATEMENTS

"Management's Discussion and Analysis of Results of Operations" contain
"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, those discussed in this
section. Factors that could cause future results to differ from these
expectations include 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 Company's success in and expense
associated with developing, introducing and shipping new products; software
defects and latent technological deficiencies in new products; changes in
operating expenses; inability to attract or retain consulting, sales and/or
engineering talent; changes in customer requirements; evolving industry
