NOTE 3 - EQUITY FINANCING

In March 1997, the Board of Directors designated 900 shares of the Company's
authorized preferred stock as Series B Preferred Stock. This stock has a stated
value and liquidation preference of $10,000 per share, with a five percent per
annum conversion premium. The holders of Series B Preferred Stock are not
entitled to vote or to receive dividends.

On March 24, 1997, the Company sold 855 shares of Series B Preferred Stock
through a private placement at its stated value of $10,000 per share. Total net
proceeds from this private placement were $7,951,558, after reduction for
commissions and issuance costs of $598,442. In conjunction with the transaction,
the placement agent was granted a five year warrant to purchase 105,556 shares
of common stock at $4.86 per share. In addition, the investors have a right to
receive warrants to purchase common stock equal to 20% of their original
investment not converted to common stock as of March 24, 1998, divided by the
conversion price then in effect, with an exercise price equal to 115% of the
average closing bid price for five days ending on the one year anniversary date.
The Series B Preferred Stock outstanding on March 24, 1999, automatically
converts into common stock at the applicable conversion rate.

NOTE 4 - EARNINGS PER 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, warrants and convertible perferred stock for all periods, were not
included in the computation as their effect was antidilutive. However, the eight
and five percent premium earned by the preferred shareholders in 1997 was added
to the net loss for computation purposes.

                                       6
<PAGE>
 
The FASB has issued Statement No. 128, "Earnings Per Share," which supersedes
APB Opinion No. 15. Statement No. 128 requires the presentation of earnings per
share by all entities that have common stock or potential common stock, such as
options, warrants and convertible securities, outstanding that trade in a public
market. Those entities that have only common stock outstanding are required to
present basic earnings per-share amounts. All other entities are required to
present basic and diluted per-share amounts. Diluted per-share amounts assume
the conversion, exercise or issuance of all potential common stock instruments
unless the effect is to reduce a loss or increase the income per common share
from continuing operations. All entities required to present per-share amounts
must initially apply Statement No. 128 for annual and interim periods ending
after December 15, 1997. Earlier application is not permitted.

The adoption of Statement No. 128 would have had no effect on reported earnings
(loss) per share.

NOTE 5 - CONTINGENCY

The Company along with Stephen O'Hara, Lee B. Lewis and Dale Showers, has been
named as a defendant in a securities action captioned In re Ancor
Communications, Inc. Securities Litigation, filed in United States District
Court for the District of Minnesota on July 24, 1997. The lawsuit, a putative
class action, alleges that the Company violated sections 10(b) and 20(a) of the
Securities Exchange Act of 1934 when it allegedly made misleading public
disclosures relating to the Company's contract with Sequent Computer Systems,
Inc. and the Company's quarterly revenues and seeks compensatory losses in an
undetermined amount. The Company believes that the lawsuit is without merit and
intends to defend it vigorously. The Company is unable to determine if there
will be a material adverse outcome at this time.

     Net Sales. Net sales for the third quarter 1997 increased by approximately
$1,563,000 (84%) from 1996 to $3,423,837. Net sales for the nine months ended
September 30, 1997, increased by approximately $1,956,000 (36%) from the same
period 1996 to $7,328,414. This increase in net sales is due primarily to a
significant increase in net sales to an international customer, offset by a
decrease in sales domestically. International net sales in the third quarter
increased from approximately $114,000 in 1996 to approximately $2,985,000 in
1997, representing 87% of net sales to all customers for the third quarter 1997.
International net sales in the first nine months comprised 83% of net sales and
increased from approximately $1,254,000 in 1996 to approximately $6,112,000 in
1997. Domestic sales volume in the three and nine month periods ending September
30, 1997, decreased by 75% and 70%, respectively, from similar periods in 1996,
because several large sales transactions included in domestic revenue for the
1996 periods were not replaced in the similar 1997 periods.

The increase in net sales for the third quarter 1997 includes the effect of an
allowance against sales of $300,000 for product returns and customer stock
rotation.  The increase in net sales for the first nine months 1997 includes the
effect of an allowance against sales of $1,000,000 for product returns and
customer stock rotation.  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 has allowed product returns in the
past from certain customers as a marketing concession to stimulate a positive
impression of the Company and its products in the marketplace.  In addition,
resellers have incorrectly anticipated the configuration needed by end user
equipment purchasers and have requested that purchased but unused product be
exchanged for the product needed to meet the end user requirements.  Further,
certain end users have requested that they purchase their initial products from
the Company, instead of the reseller, which resulted in credits issued to the
resellers in the second half of 1996 and first quarter of 1997.  As a result of
all of these factors, the Company's net assets include a reserve to provide for
potential future return of product sold in the current and previous periods.
The reserve at September 30, 1997, was approximately $340,000 ($680,000 gross
sales less the estimated value of product to be returned).

While the Company achieved record revenues for the third quarter 1997, the
timing of orders and shipments will result in revenues varying from quarter to
quarter.  The Company currently expects that fourth quarter revenues will be
less than record third quarter revenues because of an anticipated reduction in
international shipments.

A significant portion of the Company's revenues (14% in fiscal 1996 and 83% in
the first nine months of 1997) were generated by a single customer, Hucom, Inc.
Product purchased from the Company by Hucom is remarketed to end users.  A
significant portion of Hucom's sales of Ancor's products in fiscal 1996 and
fiscal 1997 have been to one end user.  In future periods, Hucom's sales of
Ancor's products to this end user are expected to be significantly less than in
fiscal 1997.  The Company's business would be materially, adversely impacted if
other end users are not found to replace this level of business or if Hucom
ceased doing business with the Company unless and until additional resellers are
established.

     Gross Profit.  Gross profit in the third quarter of 1997 decreased to
$836,824, or 24.4% of sales, from $931,529, or 50.1% of sales, in the third
quarter of 1996.  Gross profit in the first nine months of 1997 decreased to
$2,405,143, or 32.8% of sales, from $2,536,497, or 47.2% of sales, for the same
period of 1996.  Included in the cost of sales for the third quarter is a
$500,000 provision for excess and obsolete inventory which had the effect of
decreasing gross profit as a percentage of sales by 14.6%.  The Company made
this provision because it believes its inventory of certain host bus adapter
cards exceeds current and future market demands as customers transition to newer
server and workstation platforms.

Gross profit is impacted by the mix of product sold within a period.  In
general, adapter cards have lower margins than switches and different switch
types have different margins.  Gross margins for the third quarter and first
nine months of 1997 were negatively impacted because the mix of product sold
during these periods carried lower margins than those sold in comparable periods
in 1996.

     Operating Expense.  The Company's operating expenses for the third quarter
of 1997 were $3,343,168, or 97.6% of net sales, compared to $2,186,512, or
117.5% of net sales, in the third quarter of 1996. Operating expenses for the
first nine months of 1997 were $8,655,681, or 118.1% of net sales, compared to
$5,567,748, or 103.6% of net sales, in the same period of 1996. The Company
believes that the level of expense incurred is appropriate to address the
opportunities available to it in the networking and Original Equipment
Manufacturer ("OEM") storage marketplaces. The increase in operating expenses is
due to an increase in the cost for personnel, increased marketing and sales
expenses to prepare for the OEM storage market, and increased depreciation. The
number of employees at September 30, 1997 was 10% greater than at September 30,
1996, resulting in personnel and related expenses increasing $604,000 in the
third quarter 1997 as compared with the third quarter 1996, and $1,420,000 in
the first nine months of 1997 as compared with the same period 1996.
Additionally, the Company's ongoing aggressive commitment to front end spending
for marketing and sales tactics resulted in advertising and marketing expenses
increasing $208,000 in the third quarter 1997 as compared with the third quarter
1996, and $764,000 in the first nine months of 1997 as compared with the same
period 1996. Further, primarily due to amortization of capitalized software
development costs, depreciation and amortization expense increased $165,000 in
the third quarter 1997 as compared with the third quarter 1996, and $472,000 in
the first nine months of 1997 as compared with the same period 1996.

In the third quarter 1997 a charge of $250,000 was recorded to reflect
compensation owed a former executive of the Company whose services are being
discontinued.  The amount of the accrual was based on the compensation payable
to such officer under the terms of the officer's employment contract.

     Other Income (Expense)  Interest expense decreased in the first nine months
of 1997 to $10,526 from $63,720 in the first nine months of 1996 as a result of
the Company's repayment of a $1.5 million note payable in June 1996.  Interest
income of $59,070 and approximately $62,161 in the third quarters of 1997 and
1996, respectively, and $176,281 and $196,094 in the first nine month periods of
1997 and 1996, respectively, was earned from the investment of the net proceeds
of preferred stock offerings occurring in March of each year.

     Net Loss  The Company's net loss increased to $2,452,636, or $0.23 per
share in third quarter 1997, compared to a net loss of $1,192,920, or $0.12 per
share in third quarter 1996.  Net loss for the first nine months of 1997
increased to $6,084,783, or $0.59 per share, compared to a net loss of
$2,898,877, or $0.32 per share in the same period 1996.  The greater net loss is
primarily attributable to greater operating expenses.


LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

The Company's cash, cash equivalents and short-term investments were $4,109,027
as of September 30, 1997, compared to $1,510,571 as of December 31, 1996.  Cash
flows used in operating activities totaled $4,423,971, due to the operating
loss, net payments to vendors and inventory purchases in anticipation of future
sales, as offset by net collections of accounts receivable.  Cash flows used in
investing activities totaled $3,111,757 as a result of the purchase of short-
term investments and equipment, which included upgrades of engineering desktop

                                       10
<PAGE>
 
systems and continued internal construction of testing and tooling equipment for
the next generation of Fibre Channel switching products.  In March 1997, the
Company completed a private placement transaction by selling 855 shares of
Series B Preferred Stock which provided net proceeds of approximately
$8,000,000. Approximately 490 of these preferred shares remain unconverted as of
October 29, 1997. In conjunction with the transaction, the placement agent was
granted a five year warrant to purchase 105,556 shares of common stock at $4.86
per share. Approximately 90,000 of these warrants remain unexercised as of
October 29, 1997. In addition, the investors have a right to receive warrants to
purchase common stock equal to 20% of their original investment not converted to
common stock as of March 24, 1998, divided by the conversion price then in
effect, with an exercise price equal to 115% of the average closing bid price
for five days ending on the one year anniversary date.

The Company believes that the capital received from the private placement,
together with interest earned thereon, and anticipated revenues from operations
will provide adequate liquidity to fund growth, operations, and capital
expenditures for 1997.  However, the Company aniticipates the need to secure
additional financing in order to fund operating and working capital requirements
in the first half of 1998.  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.

     Shareholder Litigation.  The Company along with Stephen O'Hara, Lee B.
Lewis and Dale Showers, has been named as a defendant in a securities action
captioned In re Ancor Communications, Inc. Securities Litigation, filed in
United States District Court for the District of Minnesota on July 24, 1997.
The lawsuit, a putative class action, alleges that the Company violated sections
10(b) and 20(a) of the Securities Exchange Act of 1934 when it allegedly made
misleading public disclosures relating to the Company's contract with Sequent
Computer Systems, Inc. and the Company's quarterly revenues and seeks
compensatory losses in an undetermined amount.  The Company believes that the
lawsuit is without merit and intends to defend it vigorously.  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..  At September 30, 1997, the Company had incurred
approximately $25,000 in legal expenses related to the suit.

     Year 2000 Issue.  Per SEC Staff Legal Bulletin No. 5 issued October 8,
1997, the Company has investigated the impact of the Year 2000 ("Y2K") issue on
its information systems.  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.  The developer has informed the
Company it will continue its testing throughout 1997 and advise its clients of
these test results as they are available.  Additionally, the Company's products,
including software, are not date sensitive as to functionality.  Therefore, Y2K
is not expected to have a material effect on the Company's financial position,
operations or cash flow.

NOTE 3 - EQUITY FINANCING

In March 1997, the Board of Directors designated 900 shares of the Company's
authorized preferred stock as Series B Preferred Stock. This stock has a stated
value and liquidation preference of $10,000 per share, with a five percent per
annum conversion premium. The holders of Series B Preferred Stock are not
entitled to vote or to receive dividends.

On March 24, 1997, the Company sold 855 shares of Series B Preferred Stock
through a private placement at its stated value of $10,000 per share. Total net
proceeds from this private placement were $7,951,558, after reduction for
commissions and issuance costs of $598,442. In conjunction with the transaction,
the placement agent was granted a five year warrant to purchase 105,556 shares
of common stock at $4.86 per share. In addition, the investors have a right to
receive warrants to purchase common stock equal to 20% of their original
investment not converted to common stock as of March 24, 1998, divided by the
conversion price then in effect, with an exercise price equal to 115% of the
average closing bid price for five days ending on the one year anniversary date.
The Series B Preferred Stock outstanding on March 24, 1999, automatically
converts into common stock at the applicable conversion rate.

NOTE 4 - EARNINGS PER 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, warrants and convertible perferred stock for all periods, were not
included in the computation as their effect was antidilutive. However, the eight
and five percent premium earned by the preferred shareholders in 1997 was added
to the net loss for computation purposes.

                                       6
The FASB has issued Statement No. 128, "Earnings Per Share," which supersedes
APB Opinion No. 15. Statement No. 128 requires the presentation of earnings per
share by all entities that have common stock or potential common stock, such as
options, warrants and convertible securities, outstanding that trade in a public
market. Those entities that have only common stock outstanding are required to
present basic earnings per-share amounts. All other entities are required to
present basic and diluted per-share amounts. Diluted per-share amounts assume
the conversion, exercise or issuance of all potential common stock instruments
unless the effect is to reduce a loss or increase the income per common share
from continuing operations. All entities required to present per-share amounts
must initially apply Statement No. 128 for annual and interim periods ending
after December 15, 1997. Earlier application is not permitted.

The adoption of Statement No. 128 would have had no effect on reported earnings
(loss) per share.

NOTE 5 - CONTINGENCY

The Company along with Stephen O'Hara, Lee B. Lewis and Dale Showers, has been
named as a defendant in a securities action captioned In re Ancor
Communications, Inc. Securities Litigation, filed in United States District
Court for the District of Minnesota on July 24, 1997. The lawsuit, a putative
class action, alleges that the Company violated sections 10(b) and 20(a) of the
Securities Exchange Act of 1934 when it allegedly made misleading public
disclosures relating to the Company's contract with Sequent Computer Systems,
Inc. and the Company's quarterly revenues and seeks compensatory losses in an
undetermined amount. The Company believes that the lawsuit is without merit and
intends to defend it vigorously. The Company is unable to determine if there
will be a material adverse outcome at this time.

Net Sales. Net sales for the third quarter 1997 increased by approximately
$1,563,000 (84%) from 1996 to $3,423,837. Net sales for the nine months ended
September 30, 1997, increased by approximately $1,956,000 (36%) from the same
period 1996 to $7,328,414. This increase in net sales is due primarily to a
significant increase in net sales to an international customer, offset by a
decrease in sales domestically. International net sales in the third quarter
increased from approximately $114,000 in 1996 to approximately $2,985,000 in
1997, representing 87% of net sales to all customers for the third quarter 1997.
International net sales in the first nine months comprised 83% of net sales and
increased from approximately $1,254,000 in 1996 to approximately $6,112,000 in
1997. Domestic sales volume in the three and nine month periods ending September
30, 1997, decreased by 75% and 70%, respectively, from similar periods in 1996,
because several large sales transactions included in domestic revenue for the
1996 periods were not replaced in the similar 1997 periods.

                                       8
The increase in net sales for the third quarter 1997 includes the effect of an
allowance against sales of $300,000 for product returns and customer stock
rotation.  The increase in net sales for the first nine months 1997 includes the
effect of an allowance against sales of $1,000,000 for product returns and
customer stock rotation.  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 has allowed product returns in the
past from certain customers as a marketing concession to stimulate a positive
impression of the Company and its products in the marketplace.  In addition,
resellers have incorrectly anticipated the configuration needed by end user
equipment purchasers and have requested that purchased but unused product be
exchanged for the product needed to meet the end user requirements.  Further,
certain end users have requested that they purchase their initial products from
the Company, instead of the reseller, which resulted in credits issued to the
resellers in the second half of 1996 and first quarter of 1997.  As a result of
all of these factors, the Company's net assets include a reserve to provide for
potential future return of product sold in the current and previous periods.
The reserve at September 30, 1997, was approximately $340,000 ($680,000 gross
sales less the estimated value of product to be returned).

While the Company achieved record revenues for the third quarter 1997, the
timing of orders and shipments will result in revenues varying from quarter to
quarter.  The Company currently expects that fourth quarter revenues will be
less than record third quarter revenues because of an anticipated reduction in
international shipments.

A significant portion of the Company's revenues (14% in fiscal 1996 and 83% in
the first nine months of 1997) were generated by a single customer, Hucom, Inc.
Product purchased from the Company by Hucom is remarketed to end users.  A
significant portion of Hucom's sales of Ancor's products in fiscal 1996 and
fiscal 1997 have been to one end user.  In future periods, Hucom's sales of
Ancor's products to this end user are expected to be significantly less than in
fiscal 1997.  The Company's business would be materially, adversely impacted if
other end users are not found to replace this level of business or if Hucom
ceased doing business with the Company unless and until additional resellers are
established.

     Gross Profit.  Gross profit in the third quarter of 1997 decreased to
$836,824, or 24.4% of sales, from $931,529, or 50.1% of sales, in the third
quarter of 1996.  Gross profit in the first nine months of 1997 decreased to
$2,405,143, or 32.8% of sales, from $2,536,497, or 47.2% of sales, for the same
period of 1996.  Included in the cost of sales for the third quarter is a
$500,000 provision for excess and obsolete inventory which had the effect of
decreasing gross profit as a percentage of sales by 14.6%.  The Company made
this provision because it believes its inventory of certain host bus adapter
cards exceeds current and future market demands as customers transition to newer
server and workstation platforms.

Gross profit is impacted by the mix of product sold within a period.  In
general, adapter cards have lower margins than switches and different switch
types have different margins.  Gross margins for the third quarter and first
nine months of 1997 were negatively impacted because the mix of product sold
during these periods carried lower margins than those sold in comparable periods
in 1996.

Operating Expense.  The Company's operating expenses for the third quarter
of 1997 were $3,343,168, or 97.6% of net sales, compared to $2,186,512, or
117.5% of net sales, in the third quarter of 1996. Operating expenses for the
first nine months of 1997 were $8,655,681, or 118.1% of net sales, compared to
$5,567,748, or 103.6% of net sales, in the same period of 1996. The Company
believes that the level of expense incurred is appropriate to address the
opportunities available to it in the networking and Original Equipment
Manufacturer ("OEM") storage marketplaces. The increase in operating expenses is
due to an increase in the cost for personnel, increased marketing and sales
expenses to prepare for the OEM storage market, and increased depreciation. The
number of employees at September 30, 1997 was 10% greater than at September 30,
1996, resulting in personnel and related expenses increasing $604,000 in the
third quarter 1997 as compared with the third quarter 1996, and $1,420,000 in
the first nine months of 1997 as compared with the same period 1996.
Additionally, the Company's ongoing aggressive commitment to front end spending
for marketing and sales tactics resulted in advertising and marketing expenses
increasing $208,000 in the third quarter 1997 as compared with the third quarter
1996, and $764,000 in the first nine months of 1997 as compared with the same
period 1996. Further, primarily due to amortization of capitalized software
development costs, depreciation and amortization expense increased $165,000 in
the third quarter 1997 as compared with the third quarter 1996, and $472,000 in
the first nine months of 1997 as compared with the same period 1996.

In the third quarter 1997 a charge of $250,000 was recorded to reflect
compensation owed a former executive of the Company whose services are being
discontinued.  The amount of the accrual was based on the compensation payable
to such officer under the terms of the officer's employment contract.

     Other Income (Expense)  Interest expense decreased in the first nine months
of 1997 to $10,526 from $63,720 in the first nine months of 1996 as a result of
the Company's repayment of a $1.5 million note payable in June 1996.  Interest
income of $59,070 and approximately $62,161 in the third quarters of 1997 and
1996, respectively, and $176,281 and $196,094 in the first nine month periods of
1997 and 1996, respectively, was earned from the investment of the net proceeds
of preferred stock offerings occurring in March of each year.

     Net Loss  The Company's net loss increased to $2,452,636, or $0.23 per
share in third quarter 1997, compared to a net loss of $1,192,920, or $0.12 per
share in third quarter 1996.  Net loss for the first nine months of 1997
increased to $6,084,783, or $0.59 per share, compared to a net loss of
$2,898,877, or $0.32 per share in the same period 1996.  The greater net loss is
primarily attributable to greater operating expenses.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

The Company's cash, cash equivalents and short-term investments were $4,109,027
as of September 30, 1997, compared to $1,510,571 as of December 31, 1996.  Cash
flows used in operating activities totaled $4,423,971, due to the operating
loss, net payments to vendors and inventory purchases in anticipation of future
sales, as offset by net collections of accounts receivable.  Cash flows used in
investing activities totaled $3,111,757 as a result of the purchase of short-
term investments and equipment, which included upgrades of engineering desktop

                                       10
systems and continued internal construction of testing and tooling equipment for
the next generation of Fibre Channel switching products.  In March 1997, the
Company completed a private placement transaction by selling 855 shares of
Series B Preferred Stock which provided net proceeds of approximately
$8,000,000. Approximately 490 of these preferred shares remain unconverted as of
October 29, 1997. In conjunction with the transaction, the placement agent was
granted a five year warrant to purchase 105,556 shares of common stock at $4.86
per share. Approximately 90,000 of these warrants remain unexercised as of
October 29, 1997. In addition, the investors have a right to receive warrants to
purchase common stock equal to 20% of their original investment not converted to
common stock as of March 24, 1998, divided by the conversion price then in
effect, with an exercise price equal to 115% of the average closing bid price
for five days ending on the one year anniversary date.

The Company believes that the capital received from the private placement,
together with interest earned thereon, and anticipated revenues from operations
will provide adequate liquidity to fund growth, operations, and capital
expenditures for 1997.  However, the Company aniticipates the need to secure
additional financing in order to fund operating and working capital requirements
in the first half of 1998.  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.

     Shareholder Litigation.  The Company along with Stephen O'Hara, Lee B.
Lewis and Dale Showers, has been named as a defendant in a securities action
captioned In re Ancor Communications, Inc. Securities Litigation, filed in
United States District Court for the District of Minnesota on July 24, 1997.
The lawsuit, a putative class action, alleges that the Company violated sections
10(b) and 20(a) of the Securities Exchange Act of 1934 when it allegedly made
misleading public disclosures relating to the Company's contract with Sequent
Computer Systems, Inc. and the Company's quarterly revenues and seeks
compensatory losses in an undetermined amount.  The Company believes that the
lawsuit is without merit and intends to defend it vigorously.  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..  At September 30, 1997, the Company had incurred
approximately $25,000 in legal expenses related to the suit.

     Year 2000 Issue.  Per SEC Staff Legal Bulletin No. 5 issued October 8,
1997, the Company has investigated the impact of the Year 2000 ("Y2K") issue on
its information systems.  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.  The developer has informed the
Company it will continue its testing throughout 1997 and advise its clients of
these test results as they are available.  Additionally, the Company's products,
including software, are not date sensitive as to functionality.  Therefore, Y2K
is not expected to have a material effect on the Company's financial position,
operations or cash flow.
