Item 1.  Business

General
- -------

Ancor Communications, Incorporated ("the Company"), incorporated in 1986, is
recognized as a leading developer of Fibre Channel network products. Fibre
Channel is a high bandwidth, low latency advance in data communications
technology developed under the auspices of the American National Standards
Institute (ANSI). The Company develops, manufactures, and markets Fibre Channel
switches, interface adapters and application specific integrated circuits
(ASICs).

In 1992, the Company delivered its first prototype Fibre Channel switches and
interface adapters. Commercial Fibre Channel switch and interface deliveries
began in 1993. Since that product introduction, joint development and marketing
alliances and significant customer relationships have been achieved with major
industry players such as IBM, Nippon Telephone & Telegraph Corp, AT&T and Sun
Microsystems. The Company's Fibre Channel products are used by organizations
worldwide for enhanced network performance, scalability and connectivity. Fibre
Channel enables the transfer of data at speeds ranging from 266 Mbps to 1
Gigabit per second, which is approximately 7 to 100 times faster than the speeds
of other existing local area networks.

Since its inception, the Company's core technology has been built around the
utilization of fiber optic cable for data transmission. Originally, through its
Anderson Cornelius division, the Company provided fiber optic manufacturing data
collection systems to Ford Motor Company. In 1989, the Company began selling its
fiber optic defense communication products to the U.S. Navy. Its current Fibre
Channel product category was initiated in 1988 when the Company participated as
an original member of the founding task group of the ANSI committee dedicated to
the creation of the Fibre Channel standard. Today the Company -- an active
member of the ANSI Fibre Channel committee and the Fibre Channel Association --
focuses entirely on the development of Fibre Channel solutions.

Products
- --------

The Company's family of Fibre Channel products currently consists of switches,
adapters, routers and ASICs sold as integrated data communication systems or as
separate components. The Company's adapters are designed to be installed in
personal computers, workstations and other devices that are interconnected to
the Company's Fibre Channel switches.

The Company's patented switch enables networks of up to 3072 nodes to be built
by linking multiple switches in 8, 16 and 64 node increments. Through the Fibre
Channel switch, users are able to establish multiple simultaneous direct connect
and shared connect links. This technology, called two-dimensional switching, is
important because it provides the advantage of both direct and shared links in a
single network.

                                       3
<PAGE>
 
Direct connect links create an actual physical, dedicated connection between two
devices with the entire bandwidth available to serve each direct link, thus
providing a fast and reliable medium for sending large volumes of data. Shared
connect links send and receive data without establishing a dedicated physical
connection so that other devices can also use the medium. Shared connect links
are more efficient for smaller data transmissions because the overhead of
establishing a direct connect link is avoided.

The Company's FCS/tm/ 266 switch completed in 1993, and its FCS/tm/ 1062,
completed in 1995, have been shipped to over 80 customers. Net sales of these
switches accounted for approximately $4.2 million of revenue in 1996, $2.0
million of revenue in 1995, and $0.9 million of revenue in 1994.

The Company's adapters provide an "intelligent" interface between the Fibre
Channel switch and varying hardware devices. This interface is designed to
permit higher speed data transfers to or from the host device and shift
communications responsibilities from the host system to the adapter, thereby
reducing overhead. The Company's adapters control communications by an imbedded
I/O processor which manages all data transfer and Fibre Channel communications.
The following is a list of the Company's adapters, together with the primary
hardware system for which each adapter was designed:

          Adapter Type                 Primary Hardware System
          ------------                 -----------------------

              MCA                            IBM, AT&T/NCR
              EISA                     Hewlett-Packard Company,
                                        Silicon Graphics, Inc.
              VME                       Silicon Graphics, Inc.
              SBus                      Sun MicroSystems, Inc.
              PCI                          Intel Corporation
                                        Silicon Graphics, Inc.

The Company began selling its MCA, EISA and VME adapters commercially during
1993. SBus and PCI adapters were introduced in 1995. Adapter net sales totaled
approximately $1.8 million of revenue in 1996, $1.6 million of revenue in 1995,
and $1.4 million of revenue in 1994.

The Company's Fibre Link products route traffic among a combination of Fibre
Channel systems, Unix systems and Netware networks to meet diverse enterprise
communications requirements. Fibre Link products were introduced in 1995 with
net sales of approximately $300,000 in 1996 and $250,000 in 1995.

The Company's ASICs provide building blocks at the chip level for implementing
Fibre Channel technology. These ASICs combine a number of Fibre Channel
functions in a single chip and thereby substantially reduce the number of
components needed to implement Fibre Channel switches and adapters. The Company
is not actively marketing its proprietary ASIC. The Company's ASICs are a
component of its adapters and switches.

                                       4
<PAGE>
 
The Company closed its Anderson Cornelius division in 1994 because its plant
floor data collection systems were not central to its Fibre Channel direction,
and discontinued its defense communications products in 1995 for that same
reason. Plant floor communications sales approximated $1,200,000 in 1994.
Defense sales approximated $390,000 and $847,000 in 1995, and 1994,
respectively.

Fibre Channel Market
- --------------------

The market for Fibre Channel addresses those customers who need to transfer
large amounts of data reliably at high speeds without network degradation. The
Fibre Channel market encompasses numerous applications within the multi-billion
dollar data and network communications market. Various market research firms,
such as EMF Associates and Ryan, Hankin, Kent Inc., estimate the market for
Fibre Channel products in the year 2000 will be over $1.0 billion.


Sales and Marketing
- -------------------

The Company's internal sales force develops sales opportunities with original
equipment manufacturers, system integrators, various indirect selling channels
and major end users. Sales efforts are concentrated in North America, Europe and
the Pacific Basin. In addition to direct selling, various marketing and
promotional techniques are employed to increase sales, including seminars, trade
shows, media advertising and sales agencies.

As of February 28, 1997, the sales organization was made up of thirteen field
sales and application engineering personnel and seven support professionals.

In 1996, Hucom (Japan) and Falcon Systems accounted for 41% and 12% of revenue
respectively. In 1995, Hucom (Japan) accounted for 24% of revenue, while in
1994, the U.S. Government, Hewlett-Packard and Ford Motor Company accounted for
17%, 14% and 12% of revenue respectively.  See Note 5 to the financial 
statement.

Competition
- -----------

The Company is aware of other companies, such as Hewlett-Packard Company, which
have developed a Fibre Channel switch. A number of companies, including Brocade
Communications, Inc., NEC Corporation and McDATA Corporation have also announced
switch development efforts. The Company is also aware that IBM is developing
Fibre Channel products and other companies, including Hewlett-Packard Company,
Adaptec, Inc., Jaycor Corporation, Interphase Corporation and Emulex, are
developing Fibre Channel adapters and other components. The Company anticipates
others will develop Fibre Channel products in the near future. Other Fibre
Channel products will compete with the Company's products, including those that
may be offered by IBM which may incorporate certain aspects of the Company's
technology. The Company believes the introduction of additional competitors will
enhance market acceptance of Fibre Channel technology.

                                       5
<PAGE>
 
The primary challenge of Fibre Channel is to gain industry acceptance over other
technologies addressing data communications needs. Despite the limitations of
existing network technology services such as FDDI, Ethernet and Token Ring,
provided by IBM and others, users will not generally replace them until system
demands significantly strain their capacity. Interim solutions are available to
enhance existing network capacity, such as greater segmentation of networks
which require an additional investment in bridges, hubs or routers. The Company
believes that those solutions are temporary and will not adequately fulfill
future network demands.

Asynchronous Transfer Mode ("ATM") and gigabit ethernet are viewed by many to be
the most significant Fibre Channel competitors in the replacement of existing
data communications networks. ATM products are available from a number of
companies, including IBM. However, there are several disadvantages to ATM that
are overcome with Fibre Channel. Because ATM is a single dimensional technology,
system performance degrades as the number of users increases. Also, because of
the small data block size and the software complexity of ATM, latency is high
for data intensive applications. Gigabit ethernet is a developing technology
which is still in its early stages.

A number of participants in the data communications industry, including the
Company, view Fibre Channel, gigabit ethernet and ATM as complementary
technologies and envision ATM, gigabit ethernet and Fibre Channel coexisting in
the same network. Fibre Channel speed and reliability advantages can be used for
LAN backbone applications, while ethernet technologies will connect many
conventional desktop applications, and ATM can tie LANs to WANs where greater
distance is required.

Intellectual Property Rights
- ----------------------------

The Company attempts to protect the proprietary aspects of its product through
patents, copyrights, trade secret law and non-disclosure safeguards. The Company
has one U.S. patent covering certain aspects of its switch. The source code for
the software contained in its products is protected by copyright law. The
Company intends to continue to seek patents on its products when appropriate. In
addition, the Company protects its trade secrets by, among other things,
maintaining non-disclosure and confidentiality agreements with its employees,
vendors and customers.

Research and Development
- ------------------------

The Company believes that its success depends in part on its ability to continue
to enhance its existing Fibre Channel products and to develop new products. The
Company's current efforts are focused on development of additional switches,
adapters and ASICs for faster, more efficient communication with more types of
host devices and operating systems. As a result, the Company has developed and
capitalized, and is currently utilizing, its own internally-built test, 
tooling and software, to assist in further development of its products.
Additionally, the Company has developed software drivers which are sold with its
adapters and switches. The development costs associated with these drivers after
the establishment of technological feasibility are capitalized and amortized to
cost of goods sold.

                                       6
<PAGE>
 
     While the Company's capital and human resource requirements are minimized
     through its strategic design development and contract manufacturing
     relationships, the Company will continue to dedicate substantial
     expenditures to research and development. Research and development
     expenditures were $3,198,155, $2,542,407, and $2,056,020 for 1996, 1995 and
     1994 respectively.

     Manufacturing
     -------------

     The Company subcontracts a majority of its production activities, including
     the manufacture, assembly and testing of the Company's proprietary Fibre
     Channel designs, to organizations specializing in contract manufacturing.
     The Company conducts its own development, design and production management
     efforts.

     During 1995, to improve product lead times, quality and cost efficiency,
     the Company changed its primary contract manufacturer.  Purchases from this
     manufacturer were approximately $5,100,000 and $870,000 in 1996 and 1995,
     respectively.  Management believes that alternative contract manufacturers
     are available in the event the Company is unable to obtain service from
     this manufacturer.

     The majority of the components used in the Company's products are generally
     available from multiple sources.  Some electrical components used in the
     Company's hardware products  are from time to time in short supply.
     Certain components may be available from only a single source at a given
     time.  Future shortages of components could result in production delays or
     reductions in product shipments that would adversely affect the Company's
     business.

     Employees
     ---------

     As of February 28, 1997, the Company had 70 full time employees and 1 part
     time employee, including 39 in engineering and product development, 20 in
     sales and marketing, 5 in manufacturing and 7 in general administration and
     finance.  None of the Company's employees is represented by a labor union
     or subject to any collective bargaining agreement.  The Company has never
     experienced any work stoppages and it believes its employee relations are
     good.


     Item 2.  Properties
     
     The Company's executive offices and manufacturing facility are located in
     Minnetonka, Minnesota, where it leases 27,560 square feet of space under a
     lease that expires in April 1998.  The annual rent is approximately
     $103,350.  The facility is adequate to meet the Company's current
     requirements, and, in the opinion of management, is adequately covered by
     insurance.

</TABLE>

     Net Sales  Net sales for 1996 increased by $1,584,889 (34%) from 1995 to
$6,257,840. This increase in net sales is due to (i) a significant increase in
net sales to Hucom, Inc., the Company's Japanese distributor, (ii) to increased
market acceptance of the Company's Fibre Channel products, (iii) continued
strength in the data networking market, and (iv) increases in network capacity
requirements. Net sales to Hucom, Inc. increased $1,459,000 (129.6%) to
$2,585,000 in 1996, representing 41% of net sales for the year. The market
acceptance of the Company's products are attributable to the breadth of the
Company's product offering for switches and adapters and the Company's ability
to deliver complete Fibre Channel networking solutions for different
connectivity environments. In 1996, net sales of switches increased by
approximately $2,200,000 (110%) to approximately $4,200,000 and net sales of
adapters increased approximately $200,000 (12.5%) to approximately $1,800,000.

The 1996 net sales increase was partially offset by significant unanticipated
product returns, which began during the second and third quarters of the year.
The Company does not generally provide customers with a right of return at the
date of sale. However, in response to significant pressures from the
marketplace, the Company allowed product returns from certain customers as a
marketing concession to stimulate a positive impression of the Company and its
products in the marketplace. Additionally, certain customers had difficulty
integrating the new technology of the Company's products and negotiated product
returns. As a result, the Company issued significant credits for sales returns
in 1996, including (i) a $700,000 credit granted to a customer in the third
quarter of 1996 as a result of the customer significantly modifying its network
design after shipment by the Company, (ii) a fourth quarter sales return of
$660,000 for a contract cancellation, and (iii) the recording of a sales returns
reserve of $300,000 at December 31, 1996 for estimated future product returns.

The $660,000 fourth quarter sales return relates to the January 1997
cancellation of an OEM contract by Sequent Computer Systems, Inc. (Sequent), a
reseller of the Company's Fibre Channel switches. After acceptance of the
Company's shipment, Sequent discovered an interoperability conflict between
Sequent's NUMA-Q technologies and the Fibre Channel technologies. The Company
agreed to accept the product return and to issue a credit for the previous sale.

At December 31, 1996, the Company recorded a net sales return reserve of
$150,000 ($300,000 gross sales less the estimated value of the product to be
returned) as an estimate of future anticipated returns of product. The recording
of this reserve is in recognition of the difficulty in obtaining market
penetration of the Company's new technology and the necessity to make
concessions to customers during the initial introduction of a new technology
product.

Net sales for 1995 decreased $88,050 (1.8%) to $4,672,951. However, there was a
substantial shift in sales to Fibre Channel product. Net sales of switches
increased approximately $1,100,000 (133.6%) to approximately $2,004,000, net
sales of adapters increased approximately $122,000 (8.5%) to approximately
$1,554,000, and the initial introduction of Fibre Link product sales were
approximately $254,000 in 1995. These increases were offset by a reduction of
sales caused by the closure of the Anderson Cornelius division in 1994, because
plant floor data collection systems were not central to its Fibre Channel
direction. Additionally, the Company ceased its defense communications business
in 1995. In 1995, defense sales decreased by approximately $457,000 (54.0%) to
approximately $390,000 and there were no sales of plant floor communication
systems compared to sales of such systems of approximately $1,400,000 in 1994.

     Gross Profit  Gross margin percentage was 43.0% in 1996, 45.8% in 1995 and
42.4% in 1994. The decrease in 1996 gross margin percentage is attributable to a
4.9 point reduction in the percentage caused by fourth quarter 1996 inventory
obsolescence, scrap and rework charges, with the offset caused by improved
margins from the switch vs. adapter mix of product sold. The 3.4% increase in
1995 gross margin percentage is attributable to reduced manufacturing overhead
and Fibre Channel start up expenses as a percentage of sales.

                                       11

     Operating Expenses  Operating expenses were $8,142,321 (130.1% of net
sales) in 1996, $5,327,043 (114.0% of net sales) in 1995 and $4,432,869 (93.1%
of net sales) in 1994. The increase in operating expenses in 1996 and 1995 are
attributable to an increase in the number of employees, increased development
costs for the network products, increased promotion costs and increased selling
expenses as sales volume increases.

Selling, general and administrative expenses (SG&A) were approximately
$4,944,000 (79.0% of net sales) in 1996; $2,785,000 (59.6% of net sales) in
1995; and $2,377,000 (49.9% of net sales) in 1994. SG&A increased in 1996 and
1995 due to the addition of sales and management personnel resulting from the
Company's increased focus on the marketing of its Fibre Channel products.
Specifically in 1996, in addition to $1.8 million of salaries, the Company
expended $368,000 in employee recruitment, and $755,000 on outfitting marketing
demonstration facilities, development of advertising and promotion campaigns and
costs to develop the worldwide Company channels of distribution. In 1995, such
expenditures amounted to $1.3 million, $61,000 and $354,000 respectively, and in
1994 were $1.1 million, $0, and $193,000 respectively.

Research and development expenses (R&D) were approximately $3,198,000 (51.1% of
net sales) in 1996; $2,542,000 (54.4% of net sales) in 1995; and $2,056,000
(43.2% of net sales) in 1994. The Company believes the introduction of new
technologies and products to the market in a timely manner is crucial to its
success, and will continue to make strategic program expenditures where
appropriate. The nature of costs for such program development activities is
primarily the employee related cost for design, prototype development and
testing. Salaries and contracted labor incurred were approximately $2,492,000 in
1996, $1,740,000 in 1995, and $1,495,000 in 1994. Engineering expenditures
increased in 1996, as the next generation of Fibre Channel switching products is
being developed. In 1995, as the Company continued to bring new Sbus and PCI
adapters to market, research and development spending increased over 1994. The
Company expects that spending for research and development will increase in
absolute dollars but may continue to vary as a percentage of net sales.

     Nonoperating Income (Expense)  Interest expense totaled $63,986 in 1996,
$153,407 in 1995 and $275,001 in 1994. In June 1996, the Company repaid a $1.5
million note payable with the proceeds of a preferred stock offering and the
conversion of warrants to common stock (see Liquidity and Capital Resources
section below), resulting in lower interest expense for the year. Similarly, in
May 1994, the Company repaid $4 million of debt with a portion of the net
proceeds of the initial public offering.

Interest income totaled $224,086 in 1996, $70,846 in 1995 and $95,026 in 1994.
The increase in 1996 is attributable to the short-term investment of a portion
of the net proceeds of the preferred stock offering and the conversion of
warrants to common stock.

     Net Loss  The Company's net loss increased to approximately $5,290,000, or
$0.60 per share in 1996, compared to a net loss of $3,269,000, or $0.44 per
share in 1995, and a net loss of approximately $2,595,000, or $0.47 per share in
1994. In addition to the increased operating loss, the net loss of $0.60 per
share for 1996 includes an adjustment of 3 cents loss per share for the effect
of the 8% accretion benefit earned by the Series A Preferred shareholders from
the date

                                       12
<PAGE>
 
of issue to the date of conversion or to the end of the reporting period,
whichever is earlier. Such accretion amounted to $331,000 for 1996.


Liquidity and Capital Resources

The Company's principal source of liquidity at December 31, 1996 was cash, cash
equivalents and short term investments of approximately $1,511,000. This
compares to approximately $1,552,000 at year end 1995, and to approximately
$1,328,000 at year end 1994. Net cash used in operating activities increased
from approximately $3,559,000 in 1994 to approximately $3,804,000 in 1995 to
approximately $8,058,000 in 1996. The increase in 1996 was due to the net
loss, as well as increases in both accounts receivable and inventories, which,
in turn, were the result of increased sales and increased stocking in
anticipation of sales growth in 1997. The 120.5% increase in receivables is
primarily attributable to (i) a $1,485,000 sale to Hucom, Inc. in the last week
of December 1996, and (ii) extended terms granted to customers as an inducement
to utilize the Company's technology. Additionally, customers are also encouraged
to install the Company's products through a free evaluation period lasting over
a number of months. This equipment remains the property of the Company, thus
increasing inventory, unless the evaluation is converted into a sale. The
increase in 1995 was due to an increase in receivables of approximately $831,000
and a higher net loss, without the need for significant additional investments
in inventory, prepaid expenses and accounts payable. The increase in receivables
at December 31, 1995 was due primarily to significant sales near year end,
including a couple of large contracts, and a significant increase in receivables
from value added resellers.

Cash flow used in investing activities totaled approximately $2,536,000 in 1996,
as compared with approximately $601,000 in 1995 and approximately $1,978,000 in
1994. Major capital expenditures in 1996 included upgrades and additions to
facilities, development of a new worldwide management information system,
upgrades of desktop systems, development of salable software and internally-
built testing and tooling equipment for the next generation of Fibre Channel
switching products. Investments in 1995 included design and expansion of the
Company's own Fibre Channel research network of engineering tools and software.
Cash invested in 1994 included that for short-term investments and hardware and
software for ASIC design.

Since its inception, the Company has financed its operations and met its capital
expenditure requirements from private and public sales of capital stock and from
borrowing. In 1996, the Company completed an off-shore private placement of
1,030 shares of convertible preferred stock with a stated value of $10,000 per
share, resulting in net proceeds to the Company of approximately $9,544,000
after deducting selling commissions and offering expenses. Additionally, during
the year, certain warrant holders elected to convert those warrants to 683,728
shares of common stock, resulting in net proceeds to the Company of
approximately $2,518,000, after deducting expenses of issuance, including the
cost of registering the shares pursuant to registration rights held by such
warrant holders. The proceeds of these equity transactions were used to repay
$1,500,000 of indebtedness to IBM due in June 1996, and were used to fund sales
and marketing efforts to accelerate penetration of the Company's products into
OEM, system integrator and reseller accounts, to fund research and development
efforts needed

                                       13
<PAGE>
 
to maintain technological leadership and broaden the Company's product line, and
for working capital. In 1995, the Company completed two private placements
resulting in net proceeds to the Company of approximately $4.7 million. During
the second quarter of 1994, the Company completed its initial public offering of
common stock, raising approximately $8,300,000. Of the total net proceeds, $4
million was used to pay $2 million of its obligation to IBM and $2 million to
retire 10% subordinated notes. In 1992, the Company entered into a term loan
agreement with IBM to borrow $3.5 million dollars at 8.75%. In 1993, the Company
sold $2 million principal amount of 10% subordinated notes.

Management believes that the Company must obtain additional capital to fund the
continued growth in net sales and to fund the Company's working capital
requirements, operating activities, and future capital expenditures until
profitability is achieved. The Company plans to raise additional capital from a
private placement of equity securities. In February 1997, the Company entered
into a nonbinding letter of agreement with a placement agent to raise
$10,000,000 through the issuance of 5% convertible preferred stock. As of March
13, 1997, the placement agent has informed the Company that it expects the
private placement will be fully subscribed, but is subject to investor review of
the Company's 1996 Form 10-K. The Company currently anticipates that the private
placement will close in March 1997.

The Company believes that the capital received from the private placement will
provide adequate liquidity to fund growth, operations, and capital expenditures
for 1997. However, there is no assurance that the Company will be able to
successfully complete the private placement transaction or, if necessary, obtain
capital from alternative sources at a reasonable cost or at all. If
additional capital cannot be obtained, the Company would have to substantially
reduce its growth plans and its operating costs.

                         INDEPENDENT AUDITOR'S REPORT


To the Board of Directors
Ancor Communications, Incorporated
Minnetonka, Minnesota

We have audited the accompanying balance sheets of Ancor Communications,
Incorporated as of December 31, 1996 and 1995, and the related statements of
operations, shareholders' equity, and cash flows for each of the three years in
the period ended December 31, 1996. 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 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 Ancor Communications,
Incorporated as of December 31, 1996 and 1995, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1996, in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company has incurred losses from operations, requires
additional financing, and needs to attain profitable operations. These factors
raise substantial doubt about the Company's ability to continue as a going
concern. Management's plans in regard to these matters are described in Note 2,
including plans to complete a $10,000,000 private placement through the issuance
of 5 percent convertible preferred stock in March 1997. The financial statements
do not include any adjustments that might result from the outcome of these
uncertainties.

NOTES TO FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------

Note 1.  Nature of Business and Significant Accounting Policies

Nature of business: Ancor Communications, Incorporated (the Company) operates in
one business segment, the development and marketing of various products for the
communications market. The Company's main product is fiber-optic communications
networks. The Company also previously designed, produced, and marketed system
components used in United States military communications systems. During 1995,
the Company ceased its defense communications systems business and sold the
related technology. Sales of defense communication systems totaled approximately
$390,000 and $847,000 in 1995 and 1994, respectively. During 1994, the Company
ceased the majority of its plant floor communications systems business. Sales of
plant floor communications systems totaled approximately $1,200,000 in 1994.
Sales are made to customers throughout the United States, in Japan, and in
certain other foreign countries. Credit, including foreign credit, is determined
on an individual customer basis.

Accounting estimates: The preparation of the 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.

Revenue recognition: Revenue is generally recognized at the time product is
shipped or services are provided. In certain circumstances, revenue is
recognized upon completion of production under specific contractual arrangements
for billing and delivery. At December 31, 1996, the Company recorded a reserve
for estimated future product returns (see Note 9).

Cash and cash equivalents: For purposes of reporting cash flows, the Company
considers all unrestricted cash and any U.S. Treasury bills, commercial paper,
and money market funds with an original maturity of three months or less to be
cash equivalents. The Company maintains its cash in bank deposit and money
market accounts, which, at times, exceed federally insured limits. The Company
has not experienced any losses in such accounts.

Short-term investments: Short-term investments consist primarily of investments
in money market funds and in U.S. government obligations (primarily U.S.
Treasury bills). Short-term investments are recorded at cost (which approximates
market) and mature in 1997.

Inventories: Inventories are stated at the lower of cost (first-in, first-out
method) or market.

Depreciation and amortization: Equipment purchases are stated at cost.
Depreciation is computed by the straight-line method over estimated useful lives
of five and seven years. Intangible assets consist principally of patents,
prepaid royalties, and cost in excess of net assets acquired. Amortization is
computed by the straight-line method over estimated useful lives ranging from 5
to 15 years.

NOTES TO FINANCIAL STATEMENTS

Note 1.  Nature of Business and Significant Accounting Policies (Continued)

The Company reviews its long-lived assets periodically to determine potential
impairment by comparing the carrying value of the long-lived assets with the
estimated future net undiscounted cash flows expected to result from the use of
the assets, including cash flows from disposition. Should the sum of the
expected future net cash flows be less than the carrying value, the Company
would recognize an impairment loss at that date. An impairment loss would be
measured by comparing the amount by which the carrying value exceeds the fair
value (estimated discounted future cash flows) of the long-lived assets. To
date, management has determined that no impairment of long-lived assets exists.

Fair value of financial instruments: The financial statements include the
following financial instruments: cash and cash equivalents, short-term
investments, and long-term debt. No separate comparison of fair values versus
carrying values is presented for the aforementioned financial instruments since
their fair values are not significantly different than their balance sheet
carrying amounts.

Income taxes: Deferred taxes are provided on an asset and liability method
whereby deferred tax assets are recognized for deductible temporary differences
and operating loss or tax credit carryforwards and deferred tax liabilities are
recognized for taxable temporary differences. Temporary differences are the
differences between the amounts of assets and liabilities recorded for income
tax and financial reporting purposes. Deferred tax assets are reduced by a
valuation allowance when management determines that it is more likely than not
that some portion or all of the deferred tax assets and liabilities will not be
realized. Deferred tax assets and liabilities are adjusted for the effects of
changes in tax laws and rates on the date of enactment. Income tax expense or
benefit would be the tax payable or refundable for the year plus or minus the
change in deferred tax assets and liabilities during the year.

Capitalized software development costs: The Company capitalizes software
development costs incurred after the establishment of technological feasibility.
These costs are amortized to cost of goods sold at the greater of (i) the amount
computed using the ratio of current gross revenues for the product to the total
of current and anticipated future gross revenues, or (ii) the straight-line
method over the remaining estimated economic life of the product. An original
estimated economic life ranging from one to five years is assigned to
capitalized software development costs. It is reasonably possible that those
estimates of anticipated future gross revenues, the remaining estimated economic
life of the product, or both, will be reduced significantly in the near term due
to the rapid technological change of the Company's products. Software
development costs capitalized were approximately $578,000 and $111,000 for 1996
and 1995, respectively. Software development cost amortization was approximately
$72,000 and $3,000 for 1996 and 1995, respectively.

Research and development: Research and development costs applicable to both
present and future products are charged to operations as incurred.

Net loss per common share: Net loss per common share is computed based upon the
weighted average number of common shares outstanding during the year. Common
equivalent shares, consisting of options and warrants for all periods and
convertible preferred stock in 1996, were not included in the computation as
their effect was antidilutive. However, the 8 percent premium earned by the
preferred shareholders in 1996 was added to the net loss for computation
purposes.

NOTES TO FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------

Note 2.  Corporate Liquidity

The financial statements have been prepared on a going-concern basis that
contemplates the recoverability of assets and the satisfaction of liabilities in
the ordinary course of business. In 1996, the Company incurred a net loss of
$5,289,684 and used cash in operating activities of $8,058,100. At December 31
1996, the Company has cash, cash equivalents, and short-term investments
totaling $1,510,571 and an accumulated deficit of $17,269,202.

Management believes that the Company must obtain additional capital to fund the
continued growth in net sales and to fund the Company's working capital
requirements, operating activities, and future capital expenditures until
profitability is achieved. The Company plans to raise additional capital from a
private placement of equity securities. In February 1997, the Company entered
into a nonbinding letter of agreement with a placement agent to raise
$10,000,000 through the issuance of 5% convertible preferred stock. As of March
13, 1997, the placement agent has informed the Company that it expects the
private placement will be fully subscribed, but is subject to investor review of
the Company's 1996 Form 10-K. The Company currently anticipates that the private
placement will close in March 1997.

The Company believes that the capital received from the private placement will
provide adequate liquidity to fund growth, operations, and capital expenditures
for 1997. However, there is no assurance that the Company will be able to
successfully complete the private placement transaction or, if necessary, obtain
capital from alternative sources at a reasonable cost or at all. If
additional capital cannot be obtained, the Company would have to substantially
reduce its growth plans and its operating costs.

The financial statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts or the amounts and
classification of liabilities that might be necessary should the Company be
unable to continue in existence.

Note 6.  Income Taxes (Continued)

Under existing federal tax laws, due to changes in stock ownership resulting
from the Company's initial public offering (IPO), the availability of its net
operating loss and tax credit carryforwards incurred through May 1994 will be
limited to approximately $800,000 on an annual basis.  Sales of equity
securities subsequent to the Company's IPO could further limit the availability
of these carryforwards.

Note 7.  Shareholders' Equity

Preferred stock: In 1996, the Board of Directors designated 1,100 shares of the
authorized preferred stock as Series A Preferred Stock. In March 1996, the
Company sold 1,030 shares of Series A Preferred Stock in a private placement
transaction which provided proceeds of $9,543,534, net of issuance costs of
$756,466. In addition, the placement agent was granted warrants to purchase
111,094 shares of common stock at $6.49 per share.

The Series A Preferred Stock has a stated value and liquidation preference of
$10,000, plus an 8 percent per annum premium. The holders of the Series A
Preferred Stock are not entitled to vote or to receive dividends. Each share of
Series A Preferred Stock is convertible into common stock at the option of the
holder based on its stated value at the conversion date divided by a conversion
price. The conversion price is defined as the lesser of $6.49 per share or 85
percent of the average closing bid price of the Company's common stock for the
five days preceding the conversion date. During 1996, a total of 856 shares of
Series A Preferred Stock were converted into 1,352,494 shares of common stock.

The Series A Preferred Stock also includes provisions for (i) adjustment of the
conversion rate and price in the event of stock splits, stock dividends, and
mergers, (ii) restrictions on the Company's ability to issue capital stock with
distribution or liquidation preferences senior to the Series A Preferred Stock,
(iii) registration rights, and (iv) redemption by the Company in certain
circumstances. The Series A Preferred Stock outstanding on February 23, 1999,
automatically converts into common stock at the applicable conversion rate.

Options and warrants: The Company's 1994 Long-Term Incentive and Stock Option
Plan provides for the granting of stock options, stock appreciation rights,
restricted stock awards, and performance awards to officers, directors,
employees, and independent contractors of the Company. The options may be
granted at an exercise price of not less than the fair market value of common
stock at the date of grant (110 percent for more than 10 percent shareholders).

During 1995, in connection with the private placement of common stock, the
Company granted the underwriters warrants to purchase 75,500 shares of common
stock at $5.13 per share.

During 1994, the Company issued 1,200,000 shares of common stock to IBM in
exchange for a warrant to purchase 2,736,164 shares of Company common stock. No
proceeds were received from this transaction.

Note 7.  Shareholders' Equity (Continued)

The Company has adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation.
Accordingly, no compensation cost has been recognized for the stock option plan.
Had compensation cost for the Company's stock option plan been determined based
on the fair value at the grant date for awards in 1996 and 1995 consistent with
the provisions of SFAS No. 123, the Company's net loss and net loss per share
would have been increased to the pro forma amounts indicated below:


<TABLE>

Net loss, pro forma                   (5,781,684)       (3,324,915)   
Net loss per share, as reported            (0.60)            (0.44)
Net loss per share, pro forma              (0.65)            (0.45)
</TABLE>

The above pro forma effects on net loss and net loss per share are not likely to
be representative of the effects on reported net income (loss) for future years
because options vest over several years and additional awards generally are made
each year.

The fair value of each option grant is estimated on the date of grant using the
Black-Scholes option pricing model with the following weighted average
assumptions used for grants in 1996 and 1995:

</TABLE>

The office and manufacturing facility lease requires the Company to pay real
estate taxes, insurance, and maintenance costs. Total rent expense under the
operating lease arrangements for 1996, 1995, and 1994, was approximately
$439,000, $312,000, and $320,000, respectively.

Potential contingent consideration: In connection with its 1986 acquisition of
Anderson Cornelius Company (subsequently merged into Ancor), the Company agreed
to pay additional contingent consideration. This additional consideration (up to
a remaining maximum of approximately $259,000) is payable annually at 4 percent
of Company sales in excess of $4,000,000 in any calendar year and is recorded as
cost in excess of assets acquired. Amounts payable under this arrangement were
not material in any year presented.

Profit sharing plan: The Company has a profit sharing/401(k) plan which provides
that an annual contribution, up to the maximum amount allowed as a deduction by
the Internal Revenue Code, may be contributed by the Company to the plan.
Company contributions to the plan are discretionary as determined by the Board
of Directors. No contributions were made by the Company during 1996, 1995, and
1994.

Note 8.  Commitments (Continued)

Major supplier: The Company outsources the manufacturing of its products with a
contract manufacturer. Purchases from this manufacturer were approximately
$5,086,000 and $870,000 in 1996 and 1995, respectively. The manufacturer has the
right to require that the Company purchase any excess or obsolete inventory, as
defined by the agreement, from the manufacturer. At December 31, 1996, the
Company has accrued approximately $50,000 as an estimate of the potential
commitments under this contract. Management believes that alternative contract
manufacturers are available.

Note 9.  Product Returns and Significant Fourth-Quarter Adjustments

The Company began to experience significant product returns in the second and
third quarters of 1996 as a result of rapidly changing market conditions,
changes in the Company's marketing strategies, and the difficulty of certain
customers with integrating the technology of the Company's products. At December
31, 1996, the Company has recorded a net reserve for product returns of 
$150,000 ($300,000 gross reserve, net of $150,000 estimated value of returned 
product) for estimated future product returns related to 1996 sales.

In the fourth quarter of 1996, the Company made significant adjustments relating
to customer cancellations of sales made in prior 1996 quarters, the recording of
a product returns reserve (discussed above), inventory reserves and write-offs,
and other asset write-offs. These adjustments had the effect of increasing the
fourth-quarter net loss and net loss per common share by approximately $944,000
and $0.09 per share, respectively.
