NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial information.
In the opinion of management, the interim financial statements include all
adjustments necessary for a fair presentation of the results of operations for
the interim periods presented. Operating results for the three and six months
ended June 30, 1999 are not necessarily indicative of the operating results to
be expected for the year ending December 31, 1999.

Certain information and footnote disclosures normally included in financial
statements in accordance with generally accepted accounting principles have been
condensed or omitted.

NOTE 2 - INVENTORIES

Inventories at June 30, 1999 and December 31, 1998 consisted of:

NOTE 3 - NET LOSS PER SHARE

The Company computes net loss per common share based upon the weighted average
number of common shares outstanding during the year. Potential common shares,
consisting of options, warrants and convertible preferred stock for all periods,
were not included in the computation as their effect was antidilutive. Premiums
earned by preferred shareholders are included in the net loss attributable to
common shareholders computation. Basic and diluted loss per-share amounts are
the same in each period presented.

NOTE 4 - CONTINGENCY

The Company is a defendant in a lawsuit brought by Hoyt Properties, Inc.
("Hoyt") venued in Hennepin County District Court in the State of Minnesota.
Hoyt claims that the Company breached an agreement which provided that Hoyt
would build and lease to the Company an office building to be located in Eden
Prairie, Minnesota, and asserts damages in excess of $2,500,000. The Company
asserts there was no binding agreement. The Company denies all liability, and
alleges that Hoyt refused to provide improvements desirable and necessary
 to the Company's occupancy of the proposed leased space, and multiple
contingencies, conditions, and agreements did not occur. The Company is
vigorously defending the case. There has been limited discovery completed to
date. However, there is no assurance that any judgment, order or decree against
the Company arising out of this action will not have a material adverse effect
on the Company or its business. The Company is unable to determine at this time
if there will be a material adverse outcome. No provision has been made for any
loss that may occur as a result of an adverse outcome of the suit.

NOTE 5 - UNEARNED REVENUE

On September 24, 1998 the Company entered into a technology licensing agreement
with INRANGE Technologies Corporation ("Inrange"), a unit of General Signal
Corporation. Under the agreement, Inrange paid the Company $9,000,000 in three
equal installments: on September 25, 1998, December 15, 1998, and March 31,
1999. The $9,000,000 is comprised of (i) approximately $6,200,000 for licensing
fees; (ii) approximately $800,000 in warrants to purchase 750,000 shares of the
Company's common stock at prices prices ranging from $2.50 to $10.00; and (iii)
$2,000,000 of prepaid royalties. The $6,200,000 is being recognized as revenue
evenly over the term of the agreement which is 60 months and the $2,000,000
royalty will be recorded as revenue as Inrange products ship and royalties are
earned. As of March 31, 1999, the Company has received all three $3,000,000
payments, totalling $9,000,000. This amount, reduced by the value of the
warrants granted, and further reduced by nine months of revenue recognized, has
been recorded as unearned revenue in the June 30, 1999 balance sheet.

NOTE 6 - SUN MICROSYSTEMS AGREEMENT

On June 2, 1999, the Company entered into a product purchase agreement with Sun
Microsystems, Inc. (Sun). This agreement provides Sun the ability to distribute
the Company's product for a period of two years with automatic extensions for
one-year periods unless there is written notice of termination within 180 days
of an anniversary date.

In addition, Sun received a warrant to purchase an aggregate 1,500,000 shares of
common stock of the Company at an exercise price of $7.30 per share. Upon Sun
purchasing $10,000,000 of the Company's product, the warrant will vest with
respect to 149,253 shares of common stock. Subsequent purchases of the Company's
product will vest quarterly at a rate of one warrant for each $67 of purchases
through September 30, 2002. This warrant expires five years from the date of the
agreement.

     Net Sales. Net sales for the second quarter of 1999 increased by
approximately $3,462,000 (2,527%) from 1998 to approximately $3,599,000. Net
sales for the six months ended June 30, 1999 increased by approximately
$3,939,000 (334%) to approximately $5,118,000. The increases in net sales are
attributable to (i) a large shipment of the Company's Fibre Channel switches to
Boeing for a LAN application; (ii) an increase in the shipments of the Company's
MKII Fibre Channel switches to Original Equipment Manufacturer ("OEM") customers
as a result of the Company's shift in marketing focus to opportunities in the
storage area network market; and (iii) license fee revenue of approximately
$312,000 and $623,000 in the three and six month periods ended June 30, 1999,
respectively, from INRANGE Technologies Corporation ("INRANGE"). These increases
in revenue were offset by decreases in sales to the Company's Japanese
distributor. Future sales to the Company's current Japanese distributor,
Netmarks, Inc., are uncertain.

                                       8
<PAGE>

In June 1999, the Company entered into an original equipment manufacturing
agreement with Sun Microsystems, Inc. ("Sun").  Under this agreement, the
Company expects to sell its Fibre Channel switches to Sun for incorporation into
Sun's SAN products.  Together with Sun, the Company is in the final stages of
testing its new switch for use with Sun products and expects to begin
recognizing limited amounts of revenue from Sun beginning in the fourth quarter
of 1999.  However, the Company cannot be certain that Sun will complete the
integration of the Company's switch with Sun's final SAN products and, like
other original equipment manufacturer agreements, the Company's agreement with
Sun does not guarantee that it will ultimately sell its products to Sun.

As part of the Company's agreement with Sun, it granted Sun a warrant to
purchase 1.5 million shares of the Company's common stock at an exercise price
of $7.30 per share.  The warrant shares are earned at a rate of one share for
every $67.00 of product sales to Sun through September 30, 2002.  In each period
in which the warrant shares are earned, a non-cash sales discount will be
recorded.  The amount of the non-cash sales discount will be the fair value of
the warrant shares which are earned in the period.  Fair value of the warrant
shares will be calculated by using the Black-Scholes option pricing model.  The
primary component in the Black-Scholes calculation is the value of the Company's
common stock at that time.  The value of the warrant shares, and the
corresponding sales discount, increases as the Company's stock price increases.
Conversely, the value of the warrant shares, and the corresponding sales
discount, decreases as the Company's stock price decreases.  Since the price of
the Company's stock cannot be estimated, it is not possible to estimate the
amount of the non-cash sales discount that could be recorded, but it could be
significant.  Consequently, gross margins could be impacted significantly by the
vesting of the Sun warrant shares.  For example, if the Company's share price is
$30.75, the value of a warrant share would be $29.08 based on the Black-Scholes
model.  This means that for each $67.00 in gross revenue to Sun, the Company
would record a non-cash sales discount of $29.08.  Depending on the Company's
stock price, this sales discount could cause the Company to report a negative
gross margin on sales to Sun.  Although these sales discounts will be recorded
beginning with initial sales to Sun, no warrant shares will vest until Sun
purchases an aggregate of $10 million of products from the Company.

None of the warrant shares will vest until the Company has received a total of
$10,000,000 in revenue from Sun.  During this period, any warrant shares earned
in one quarter will be revalued in subsequent quarters using the then-current
Black-Scholes option pricing model, and an additional non-cash sales discount
will be recorded if the value of the warrant shares increases or a non-cash
sales credit will be recorded if the value of the warrant shares decreases.  In
the quarter in which we achieve an aggregate of $10,000,000 in revenues from
Sun, the Company will perform a final Black-Scholes calculation for the warrant
shares earned through the end of that quarter, which will result in a final
adjustment to the non-cash sales discount.  Thereafter, warrant shares will vest
as they are earned, and the Company will record a non-cash discount quarterly
based on the Black-Scholes calculation, as described above.  No subsequent
revaluation will be recorded.

     Gross Profit. Gross profit in the second quarter of 1999 increased to
approximately $2,050,000, or 57.0% of sales, from a loss of approximately
$4,370,000 in the second quarter of 1998. Gross profit in the first six months
of 1999 increased to approximately $2,905,000, or 56.7% of sales, from a loss of
approximately $4,027,000 in the first six months of 1998. The significant
increase in gross profit shows the effect on the previous year of the special
charges of approximately $4,432,000 which were recorded in second quarter of
1998. Gross profit

                                       9
<PAGE>

excluding the effects of the special charges was approximately $62,000 (45.3% of
sales) and $405,000 (34.3% of sales) for the second quarter and first six months
of 1998, respectively.

Gross profit is affected by sales volume and its direct cost and also by
indirect costs, such as normal scrap and overhead allocations, the percentage
impact of which is decreased as sales increase.  Gross profit percentage is also
impacted by the mix of product sold within a period.  Adapter cards generally
have lower margins than switch and service revenue and various switch types have
different margins.  Excluding the effects of the previous year's special
charges, the increase in gross profit for 1999 was due primarily to increased
sales volume.  The gross profit percentage was positively impacted because (i)
indirect costs remained relatively constant; and (ii) the mix of product sold
during the period carried greater margins than that sold in the comparable
periods in 1998, particularly the revenue from INRANGE.  The INRANGE license fee
revenue positively impacts margins as substantially all the costs to develop the
licensed technology were expended in prior years.

     Selling, General and Administrative Expenses. The Company's selling,
general and administrative expenses for the second quarter of 1999 were
approximately $2,059,000, or 57.2% of net sales, compared to approximately
$1,803,000, or 1,315.5% of net sales, in the second quarter of 1998. Selling,
general and administrative expenses for the first six months of 1999 were
approximately $3,811,000, or 74.4% of net sales, compared to approximately
$3,514,000, or 298.0% of net sales in the same period of 1998. The increase was
primarily attributable to additions to staff, particularly sales and customer
account management positions, which increased personnel related expenses by
approximately $297,000 and $350,000 in the second quarter and first six months
of 1999, respectively, as compared with the same periods of 1998.

     Research and Development Expenses. The Company's research and development
expenses for the second quarter of 1999 were approximately $1,693,000, or 47.1%
of net sales, compared to approximately $1,220,000, or 890.1% of net sales, in
the second quarter of 1998. Research and development expenses for the first six
months of 1999 were approximately $3,019,000, or 59.0% of net sales, compared to
approximately $2,669,000, or 226.3% of net sales in the same period of 1998.
Increase in employee and contractor headcount caused labor costs to increase by
approximately $160,000 and $250,000 in the second quarter and first six months
of 1999, respectively. Additionally, due to the timing of non-recurring
engineering charges between periods, expenses related to product development and
enhancement increased by approximately $310,000 during the second quarter 1999,
but increased by only approximately $140,000 for the first six months of 1999 as
compared to similar periods of 1998.

     Other Income (Expense) Interest expense decreased to approximately $5,000
in the second quarter of 1999 from approximately $7,000 in the second quarter of
1998 as the Company completed its obligations on certain capitalized leases.
Similarly, interest expense decreased to approximately $11,000 in the first six
months of 1999 from approximately $20,000 in the first six months of 1998.
Interest income of approximately $60,000 and approximately $99,000 in the second
quarters of 1999 and 1998, respectively, and approximately $128,000 and
approximately $165,000 in the first six month periods of 1999 and 1998,
respectively, was earned from the investment of available cash balances. The
interest income in the second quarter and first six months of 1998 was earned
from the investment of the net proceeds of the preferred stock offering which
occurred in February 1998.

Liquidity and Capital Resources
-------------------------------

The Company's cash, cash equivalents and short-term investments were
approximately $8,115,000 as of June 30, 1999, compared to approximately
$7,447,000 as of December 31, 1998.  For the six months ended June 30, 1999,
cash flows used in operating activities totaled approximately $2,240,000, due
primarily to the operating loss and increase in end-of-period receivables,
offset by the third and final $3,000,000 installment received under the
technology licensing agreement with INRANGE.  For the six months ended June 30,
1999, cash flows used in investing activities totaled approximately $4,548,000
primarily as a result of the purchase of short-term investments with available
cash balances.  For the six months ended June 30, 1999, cash flows provided by
financing activities totaled approximately $3,503,000, primarily as a result of
the exercise of warrants and options to purchase the Company's common stock.

On July 15, 1999, the Company filed a registration statement with the Securities
and Exchange Commission for the offering of 2,500,000 shares of its common
stock.  All of the shares are being offered by the Company.  The registration
statement also includes an underwriters' over-allotment option for an additional
375,000 shares.  The Company believes that the proceeds it receives from this
offering, together with interest earned, and anticipated revenues from
operations, will provide adequate liquidity to fund its growth, operations, and
capital expenditures at least through the next 12 months.  However, the Company
may need to secure additional financing in order to fund operating and working
capital requirements after that.  There can be no assurance that additional
financing can be obtained with terms acceptable to the Company.  Any additional
equity financings may be dilutive to existing shareholders, and any debt
financing may contain restrictive covenants.  The Company's inability to obtain
additional financing if and when needed could adversely affect the Company and
its operations.


Litigation. The Company is a defendant in a lawsuit brought by Hoyt Properties,
Inc. ("Hoyt") venued in Hennepin County District Court in the State of
Minnesota. Hoyt claims that the Company breached an agreement which provided
that Hoyt would build and lease to the Company an office building to be located
in Eden Prairie, Minnesota, and asserts damages in excess of $2,500,000. The
Company asserts there was no binding agreement. The Company denies all
liability, and alleges that Hoyt refused to provide improvements desirable and
necessary to the Company's occupancy of the proposed leased space, and multiple
contingencies, conditions, and agreements did not occur. The Company is
vigorously defending the case. There has been limited discovery completed to
date. However, there is no assurance that any judgment, order or decree against
the Company arising out of this action will not have a material adverse effect
on the Company or its business. The Company is unable to determine at this time
if there will be a material adverse outcome. No provision has been made for any
loss that may occur as a result of an adverse outcome of the suit.

Year 2000 Compliance
--------------------

Year 2000 issues exist when computer systems and applications fail to recognize
date information correctly when the year changes to 2000.  If those computer
programs are not corrected, many computer systems could fail or create erroneous
results.  To date, the Company has experienced no year 2000 issues with any of
its internal systems or our products, and it does not expect to experience any.

State of Readiness. The Company has completed an assessment of year 2000
compliance for its critical operating and application systems, specifically its
enterprise-wide information systems, analysis tools, computer-aided design
systems and supporting operating system infrastructure. The Company considers a
product to be year 2000 compliant if the product's performance and functionality
are unaffected by the processing of dates before, during and after the year
2000. As a result of its assessment, the Company has determined that through
normal recurring system upgrades, the vast majority of its systems are
currently, or will be by the end of third quarter 1999, year 2000 compliant.
During fiscal 1996 the Company purchased from a world-wide supplier and
developer of information systems an enterprise-wide information system. The
developer of this information system has provided its clients written assurance
that the system will correctly function across the year 2000, as verified by
previous system tests and year 2000 certification by the International
Technology Association of America. Additionally, the Company's products,
including software, are not date sensitive as to functionality.

The potential impact of the year 2000 issue will depend not only on the
Company's internal year 2000 compliance, but also on the way in which the year
2000 is addressed by customers, vendors, service utilities, government and other
external entities. The Company is communicating with its key customers and
vendors to determine how they are addressing the year 2000 issue and to evaluate
any likely impact on its business. The Company has requested commitment dates
from these parties as to their year 2000 readiness and will continue to monitor
vendor compliance.  The efforts of third parties are not within the Company's
control, however, and their failure to remedy year 2000 issues successfully
could result in business disruption, loss of revenue and increased operating
cost.

Costs Associated with Year 2000 Compliance. Since year 2000 compliance with
regard to the Company's internal systems has been, or will be, significantly
achieved through normal system upgrades and not through accelerated or dedicated
efforts, the costs of becoming year 2000 compliant has not had and is not
expected to have a material effect on the Company's financial position,
operations or cash flow.

Risks Associated with Year 2000 Issues.  While it is impossible to evaluate
every aspect of year 2000 compliance, the Company believes that either of two
events would be its most likely year 2000 worst case scenario.  The first would
be from one or more of the Company's sole or limited source suppliers to fail to
be year 2000 compliant or to have its business negatively impacted by year 2000
issues of others.  The second would be delays in receiving orders or payments
from customers due to year 2000 problems they experience.  Similarly, the
Company's revenues could be reduced if the market for advanced electronic
products declines due to general concerns with year 2000 compliance.  At the
present time, it is not possible to determine whether any of these events is
likely to occur, or to quantify any potential negative impact they may have on
the Company's future results of operations and financial condition.

                                       12
<PAGE>

Contingency Plans.  The Company is preparing contingency plans specifying what
it will do if failures occur in its internal systems, or if important third
parties are not Year 2000 compliant. The Company anticipates the process to be
complete by early fourth quarter of 1999.

Additional Risks.  Any failure by the Company to make its products year 2000
compliant could result in a decrease in sales of its products, an increase in
allocation of resources to address year 2000 problems of its customers without
additional revenue corresponding to its dedication of resources, or an increase
in litigation costs relating to losses suffered by its customers due to year
2000 problems.  Failure of its internal systems could temporarily prevent the
Company from processing orders, issuing invoices, and developing products, and
could require it to devote significant resources to correcting these problems.

The foregoing discussion regarding Year 2000 contains forward-looking statements
which are based on management's best estimates derived using various
assumptions.  These forward-looking statements involve inherent risks and
uncertainties, and actual results could differ materially from those
contemplated by such statements.  Factors that might cause material differences
include, but are not limited to, (i) the Company's ability to obtain alternative
manufacturing sources should its current sources' operations be disrupted due to
Year 2000 complications, and (ii) the Company's ability to respond to unforeseen
Year 2000 complications.  Such material differences could result in, among other
things, business disruption, operational problems, financial loss, legal
liability and similar risks.


Safe Harbor Cautionary Statement
--------------------------------

Statements made in this Management's Discussion and Analysis that are not
historical in nature, including statements regarding the level of future
revenues and expenses, are "forward-looking statements" as defined in the
Private Securities Litigation Reform Act of 1995 and are subject to risks and
uncertainties.  Factors that may affect the Company's future performance and
results are set forth in the Company's filings with the Securities and Exchange
Commission and include: the level of market acceptance of Fibre Channel
technology and the Company's products and the timing of such acceptance; the
ability of the Company to successfully market and sell its products to OEMs and
others; the Company's ability to compete with others providing Fibre Channel
technology; the timing of customer orders, including whether customers will
purchase products from the Company at the rates and times projected by those
customers; the success of the products incorporating the Company's technology
marketed by INRANGE; the ability of the Company to develop enhancements to its
products and technology and keep pace with technological developments; the
Company's ability to manage growth; the Company's ability to attract and retain
qualified personnel; and the ability of the Company's products to interoperate
with products manufactured by others.  Retention of $2.0 million of prepaid
royalties from INRANGE is contingent upon the Company's completion of certain
deliverables defined in the Company's technology license agreement with INRANGE.

                                     ------

          QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

The Company has no history of, and does not anticipate in the future, investing
in derivative financial instruments, derivative commodity instruments or other
such financial instruments.  Contracts with international customers are entered
into in US dollars, precluding the need for foreign currency hedges.
Additionally, the Company invests in money market funds and in U.S. government
obligations (primarily U.S. Treasury bills) which experience minimal volatility.
Thus, the exposure to market risk is immaterial.


                          PART II - OTHER INFORMATION


Item 1.       Legal Proceedings.

     The Company is a defendant in a lawsuit brought by Hoyt Properties, Inc.
     ("Hoyt") venued in Hennepin County District Court in the State of
     Minnesota.  Hoyt claims that the Company breached a agreement which
     provided that Hoyt would build and lease to the Company an office building
     to be located in Eden Prairie, Minnesota, and asserts damages in excess of
     $2,500,000.  The Company asserts there was no binding agreement.  The
     Company denies all liability, and alleges that Hoyt refused to provide
     improvements desirable and necessary to the Company's occupancy of the
     proposed leased space, and multiple contingencies, conditions, and
     agreements did not occur.  The Company is vigorously defending the case.
     There has been limited discovery completed to date.  However, there is no
     assurance that any judgment, order or decree against the Company arising
     out of this action will not have a material adverse effect on the Company
     or its business.  The Company is unable to determine at this time if there
     will be a material adverse outcome.  No provision has been made for any
     loss that may occur as a result of an adverse outcome of the suit.


Item 2.  Changes in Securities.

         (a.)     None.

         (b.)     None.

         (c.)     Recent Sales of Unregistered Securities.

                  On June 2, 1999, the Company issued a warrant to purchase up
                  to 1,500,000 shares of Common Stock at a price of $7.30 per
                  share (the "Sun Warrant") to Sun Microsystems, Inc. ("Sun") in
                  connection with a Product Purchase Agreement entered into
                  between the Company and Sun. The Sun Warrant has a term of
                  five years and becomes exercisable as Sun purchases products
                  from the Company. The Sun Warrant was issued pursuant to
                  Section 4(2) of the Securities Act of 1933, as amended.
