                                   (UNAUDITED)

                                 MARCH 31, 1998


1.     THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

            THE COMPANY

                        YieldUp International Corporation (the "Company")
            develops, manufactures, and markets cleaning, rinsing, and drying
            equipment used during several steps in the manufacturing process for
            semiconductors and other defect sensitive substrates.

            BASIS OF PRESENTATION

                        The unaudited condensed consolidated financial
            information of the Company furnished herein reflects all
            adjustments, consisting only of normal recurring adjustments, which
            in the opinion of management are necessary to fairly state the
            Company's consolidated financial position, results of operations and
            cash flows for the periods presented. This Quarterly Report on Form
            10-QSB should be read in conjunction with the consolidated financial
            statements and notes thereto included in the Company's 1997 Annual
            Report on Form 10-KSB. The consolidated results of operations for
            the three-month periods ended March 31, 1998 are not necessarily
            indicative of the results to be expected for any subsequent quarter
            or for the entire year ending December 31, 1998.

            NET LOSS PER SHARE
                        Basic net loss per share is computed using the weighted
            average number of shares of Class A common stock and common stock
            outstanding during the period. Diluted net loss per share is based
            on the weighted average number of shares of common stock outstanding
            during the period and dilutive common equivalent shares from stock
            options, warrants and preferred stock outstanding during the period.
            No common shares are included for loss periods as they would be
            anti-dilutive. In the first quarter of 1998 there were 303,760
            options, 615,000 shares issuable upon conversion of outstanding
            Series A Shares and 552,359 shares issuable upon conversion of
            Series A Shares subject to call options and in the first quarter
            of 1997 there were 366,821 options outstanding that could 
            potentially dilute basic earnings per share ("EPS") in the future
            were not included in the computation of diluted EPS because to do
            so would have been antidilutive for those years.
            COMPREHENSIVE INCOME

                        In June 1997, the FASB issued Statement of Financial
            Accounting Standards ("SFAS") No. 130. "Reporting Comprehensive
            Income" which establishes standards for reporting and disclosures of
            comprehensive income and its components (revenues, expenses, gains
            and losses) in a full set of general-purpose financial statements.
            SFAS No. 130 is effective for fiscal years beginning after December
            15, 1997 and requires reclassification of financial statements for
            earlier periods to be provided for comparative purposes. The Company
            has not determined the manner in which it will present the
            information required by SFAS No. 130 in its annual financial
            statements for the year ending December 31, 1998. The Company's
            total comprehensive income (loss) for all periods presented herein
            would not have differed from those amounts reported as net income
            (loss) in the statements of operations.

3.     SERIES A CONVERTIBLE PREFERRED STOCK

            On March 30, 1998, the Company completed an equity financing in a
private placement of Series A Convertible Preferred Stock (Series A Shares) with
net proceeds to the Company of approximately $5.9 million. The Company, subject
to certain conditions, may exercise a put option for up to an additional $6
million of Series A Shares and the investors, subject to certain conditions, may
exercise a call option for up to an additional $6 million of Series A Shares.

            Under the securities purchase agreement, the Company has issued 600
shares of convertible preferred stock which are initially convertible into an
aggregate of approximately 615,000 shares of the Company's Common Stock. After
the satisfaction of certain holding periods, each of the newly issued shares of
Series A Shares is convertible, at the option of the holder, into shares of
common stock of the Company based upon a conversion price of $10.8625 per share
or if lower, 100% of the market price, defined as the lowest closing bid price
during the 20 trading days preceding a conversion. The Series A Shares bear a
dividend of 5% per year, payable in kind. The shares of Series A Shares are
subject to automatic conversion after three years if not previously converted.





                                       7

CONVERSION

            The Series A Shares are convertible into shares of Common Stock at
the election of the holder of such Series A Shares, at a price (the "Conversion
Rate") equal to the lower of the market price at the original date of issuance
of such share (the "Fixed Conversion Price") or the lowest market price during
the 20 consecutive days immediately preceding the date a holder of Series A
Shares delivers notice of his election to convert such shares. "Market price" is
generally determined by the closing price for the Registrant's Common Stock on
the applicable date.

Except upon the occurrence of certain events, the Investor(s) may convert, in
aggregate, only up to a maximum of a specified percentage of the Series A Shares
according to the following schedule:


<TABLE>
<CAPTION>
                        Days from                   % of Shares
                         Closing                    Convertible
                      ----------------              -----------
<S>                                                 <C>
                      1 through 90                       0
                      91 through 135                    20
                      136 through 180                   40
                      181 through 225                   60
                      226 through 270                   80
                      271 through term                 100
</TABLE>

Subject to certain exceptions, any Series A Shares outstanding three years after
the date such shares were initially issued will automatically convert into
shares of the Registrant's Common Stock at the then applicable Conversion Rate.

ADJUSTMENTS TO CONVERSION RATE

            The Conversion Rate is subject to proportional adjustment upon any
stock split, stock dividend or other similar change to the capital stock of the
Registrant as well other adjustments upon the issuance, or deemed issuance, of
other shares of Common Stock at a price below the then effective Fixed
Conversion Price.


POTENTIAL DILUTIVE EFFECTIVE OF CONVERSION OF SERIES A PREFERRED STOCK

            The number of shares of Common Stock which may be issued upon
conversion of the Series A Shares is dependent upon the trading price of the
Company's Common Stock at the time of conversion. To the extent that the
trading price of the Common Stock is lower than 10.8625 per share at the time
of any conversion of the currently outstanding Series A Shares, the number of
shares of Common Stock issuable upon such conversion will increase with
resulting dilution to the holders of the Company's Common Stock. There is no
minimum conversion price and thus no maximum number of shares of Common Stock
into which the Series A Shares may be converted. The Series A Shares also have
a cumulative annual dividend of 5% payable in shares of Common Stock upon
conversion. The Purchase Agreement also provides for the issuance of additional
Series A Shares, subject to certain conditions. Issuance of such additional
Series A Shares will result in additional dilution to the holders of the Common
Stock.


MANDATORY CONVERSION

             Under certain circumstances after the Registrant publicly discloses
a Change of Control Transaction, as defined in the Certificate of Designation,
the Registrant shall have the right to require that all of the outstanding
Series A Shares be converted to Common Stock.

REDEMPTION

            The holders of Series A Shares have a right to require the
Registrant to redeem the Series A Shares upon the occurrence of certain events,
including a Major Transaction, or a Triggering Event, as each is defined in the
Certificate of Designation.


LIMITATIONS ON CONVERSION AND EXERCISE

            The Purchase Agreement provides that the number of shares of the
Registrant's Common Stock issuable upon conversion of the Series A Shares cannot
exceed 20% of the outstanding shares of the Registrant's Common Stock without
the approval of the stockholders of the Registrant. Likewise, the number of
shares of the Registrant's Common Stock issuable from to time to any single
Investor cannot exceed 4.99% or more of the Registrant's outstanding Common
Stock.

EFFECT RIGHTS OF EXISTING SECURITY HOLDERS

            There is no change to the rights, preferences or privileges of the
holders of the Registrant's Common Stock as a result of the transactions which
are the subject of the Purchase Agreement. However, in addition to the dilutive
impact of the issuance of additional shares of capital stock, the Series A
Shares have a liquidation preference which entitles the holders thereof to
receive payment upon any dissolution or liquidation of the Registrant in
preference to the holders of Common Stock. The amount of such preference is
equal to $12,000 plus an amount equal to the product of (.05)(N/365)($12,000)
for each of the Series A Shares where "N" is the number of days since the
initial issuance of such shares.


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

                              RESULTS OF OPERATIONS

            The discussions in this Report contain forward-looking statements
that involve risks and uncertainties. The Company's actual results could differ
materially from those discussed herein. Factors that could cause or contribute
to such differences include, but are not limited to, those discussed in
"Business Risks" and elsewhere in this Report as well as in the Company's other
periodic reports filed with the Securities and Exchange Commission.

                   THREE MONTHS ENDED MARCH 31, 1998 AND 1997

REVENUES

            Revenues increased to $2,559,501 in the first quarter of 1998 from
$913,000 for the same period in 1997. The increase in revenues in 1998 was due
to an increase in the level of shipments for the Company's cleaning, rinsing,
and drying systems. The Company continues to modify and improve its products,
generally based on feedback from its customers. The Company has also increased
significantly the resources it is allocating to its sales and marketing
departments. The Company believes these factors, along with an increased market
acceptance of the Company's products, has lead to the increase in sales for the
Company's products. The introduction of the Omega product line which replaced
the Olympian and Hercules lines also had a significant impact on the increase in
revenues.

            In the quarter ended March 31, 1998, sales to a single customer in
the United States, Applied Materials, accounted for 37% of revenues.

            Backlog at March 31, 1998 totaled approximately $3,748,650 compared
to approximately $787,000 at March 31, 1997 and approximately $2,517,000 at
December 31, 1997. The continuing slowdown in the semiconductor equipment and
disk drive industries may negatively impact the Company's ability to book new
orders in the future until there is a change in the conditions that are reducing
capital equipment spending by manufacturers.

GROSS MARGIN

            The Company's gross margin improved to $1,090,036, or 43% of
revenues, during the first quarter of 1998 compared to negative gross margin of
($49,156), or (5%) of revenues, during the same period a year ago. This
improvement was due in part to lower manufacturing costs of the new Omega
product lines. The Company expects that future gross margins should improve to
the extent that unit shipments and revenues increase and the Company is able to
continue its transition to increased shipments of standardized products and
lower unit material costs.

RESEARCH AND DEVELOPMENT EXPENSES

            Research and development expenses were $712,634, or 28% of revenues,
in the first quarter of 1998, compared to $427,412 or 47% of revenues, for the
same period in 1997. The increase in research and development expenses was due
mainly to an increase in engineering personnel compared to the same period a
year ago. In addition, in the first quarter of 1998, the Company continued to
invest in enhancement of its existing product line. The Company expects to
continue to invest in new product research and development and enhancement of
existing products, although these expenses may decline as a percentage of
revenues to the extent revenues increase.

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES

            Selling, general, and administrative expenses were $964,854, or 38%
of revenues in the first quarter of 1998, compared to $800,742, or 88% of
revenues, for the same period in 1997. The selling, general, and administration
expenses increased due to additional commissions related to the increase in
revenues. The selling, general, and administrative expenses in the first quarter
of 1997 include a non-cash expense of $300,000 related to an amendment to
certain of the company's Class A warrants to resolve a potential dispute with
the holders of such warrants with respect to the effectiveness of a resale
registration statement relating to such Class A Shares. The terms of certain
Class A warrants were amended to give certain Class A warrant holders an
additional 0.2 shares of common stock for each Class A warrant exercised. The
Company used the Black-Scholes option pricing model to value the Class A
warrants before and after the change in terms and determined that the increase
in value was approximately $300,000. Excluding this expense, the 1997 expenses
would have been $500,742, or 55% of revenues. The Company expects that selling,
general, and administrative expenses may decline as a percentage of revenues, to
the extent revenues increase.

NET INTEREST INCOME

            Net interest income was $14,582 for first quarter of 1998 compared
to net interest expense of $6,008 for the same period in 1997. The increase in
net interest income was the result of increased interest income on short term
investments.

NET INCOME

            Net loss for the first quarter of 1998 was $572,870, or $0.10 per
share compared to a net loss of $1,283,318, or $0.38 per share for the same
period in 1997. The loss in the first quarter of 1997 included a non-cash
expense of $300,000 related to an amendment to certain of the Company's Class A
warrants to resolve a potential dispute with the holders of such warrants.
Excluding this expense, the 1997 net loss would have been $983,318, or $0.29 per
share.

            Prior to the quarter ended March 31, 1998, the Company had incurred
operating losses in each fiscal quarter since inception. Such losses have been
principally the result of the various costs associated with the Company's
product development and manufacturing activities as the Company seeks to gain
acceptance of its products in the marketplace. There can be no assurance that
the Company will be successful in generating future profits from the sales of
its products.

                         LIQUIDITY AND CAPITAL RESOURCES

            Cash, cash equivalents, and short term investment balances at March
31, 1998 totaled $8,345,097 compared to $4,058,684 at December 31, 1997. The
increase of $4,286,413 was due to the equity financing completed during the
first quarter of 1998 which resulted in total net proceeds to the Company of
approximately $5.9 million. The net cash used for operating activities during
the period was approximately $1.5 million. Principal payments of term loan and
capital lease obligations were approximately $0.1 million.




                                       10
<PAGE>   11

            At March 31, 1998 the Company had accounts receivable of $4,290,787
compared to $4,324,760 at December 31, 1997. Inventories at March 31, 1998 were
$4,783,857 compared to $4,678,600 at December 31, 1997. Net property, plant, and
equipment was $1,342,867 at March 31, 1998 compared to $1,409,817 at December
31, 1997. The decrease in net property and equipment was primarily the result of
depreciation of the assets.

            The accounts payable balance at March 31, 1998 was $1,317,206
compared to $2,512,204 at December 31, 1997. The decrease in accounts payable
was due primarily to an increase in payments made during the first quarter 1998.

            On March 30, 1998, the Company completed an equity financing in a
private placement of convertible preferred stock (Series A Shares) with net
proceeds to the Company of approximately $5,850,000. The Company, subject to
certain conditions, may exercise a put option for up to an additional $6,000,000
of Series A Shares and the investors, subject to certain conditions, may
exercise a call option for up to an additional $6,000,000 of Series A Shares.

            The Company has also obtained a commitment from a commercial lender
to receive a loan of up to $500,000 for its capital equipment and to create a
$4,000,000 revolving credit line collateralized by the Company's qualifying
accounts receivable, at an interest rate of the lender's prime rate plus 1.25%.
The funds available to the Company, if any, under such line of credit will
depend on the Company's ability to generate revenues in the near term. The
Company believes that the equity financing and the two credit facilities should
provide the Company with the necessary funds to finance operations through the
next 12 months. The Company may be required to seek additional capital beyond
that time, which may result in dilution to the current stockholders. If the
Company is unable to obtain the necessary capital, the Company's business and
operating results may be materially adversely affected.


                                 BUSINESS RISKS

GENERAL

            The Company's operations are subject to numerous risks associated
with establishing any new business, including unforeseeable expenses, delays and
complications, as well as specific risks of the semiconductor equipment
industry. The Company has incurred significant losses from its operations, and
there can be no assurance that the Company will achieve profitable operations.
The Company's smaller resources make it vulnerable to competition from larger
companies. Because the Company's technology has not been widely deployed, it
presents potential customers with uncertainty not associated with existing
equipment marketed by competitors. In addition, many semiconductor manufacturers
are reluctant to choose small companies as key suppliers due to concerns about
long-term viability and product support. Given the anticipated increasing focus
on yield management in the semiconductor manufacturing industry, equipment
manufacturers are likely to put an increased emphasis on contaminant reduction
and competitive technologies or new manufacturing technologies may be developed
which could make the Company's products obsolete. Since the Company expects to
derive substantially all of its future revenues from sales of cleaning, rinsing,
and drying systems, the Company's business, financial condition and results of
operations would be materially adversely affected by declining demand for the
Company's products or decreasing prices and margins for those products.

            The Company anticipates that it will devote significant management
time and financial resources to obtaining protection of its intellectual
property rights. The Company is attempting to obtain additional patent
protection on various aspects of its proprietary technology. These rights under
any patents issued may not





                                       11
<PAGE>   12

provide competitive advantages to the Company or prevent others from developing
competitive products or technologies similar to or more advanced than the
Company.

            The Company expects to derive a substantial portion of its revenues
from the sale of a relatively small number of systems. As a result, a small
reduction in the number of systems shipped in a quarter could have a material
adverse effect on the Company's revenues and results of operations for the
quarter. If the Company's anticipated level of revenues is not achieved for a
particular period, the Company's operating results would be adversely affected
by its inability to reduce costs. Sales of the Company's products have been, and
are expected to continue to be, characterized by a relatively long sales cycle
and may also depend upon the decision of prospective customers to upgrade the
equipment in their existing semiconductor fabrication facilities or to open new
facilities, which typically involves a significant capital commitment.

            The semiconductor equipment industry is highly cyclical and has
historically experienced periodic and often prolonged downturns. Currently, the
industry is in the midst of such a downturn. There can be no assurance that
industry downturns can be avoided and will not materially adversely affect the
Company's backlog level, business, financial condition, and results of
operations. Any downturn in the market demand for integrated circuits would
likely reduce to an even greater extent the willingness of the manufacturers of
semiconductor devices to make substantial capital expenditures and would
adversely affect the Company's business, financial condition, and results of
operations.

INTENSE COMPETITION; UNCERTAIN MARKET ACCEPTANCE

            There is intense competition in the markets for the Company's
products. The Company's smaller resources and yet to be fully proven products
make it extremely vulnerable to competition from larger companies, many of which
have significantly greater financial, employee, product development and
marketing resources. Leading competitors have a larger installed base of
products which can provide them a significant advantage over the Company because
the Company's technology has not been widely deployed and therefore presents
potential customers with uncertainty not associated with existing equipment. In
addition, many semiconductor manufacturers are reluctant to choose small
companies as key suppliers due to concerns about long term viability and product
support. There can be no assurance that the Company will overcome these
disadvantages.

            Competition for the Company's products currently comes from makers
of traditional and new cleaning, rinsing, and drying equipment. There can be no
assurance that these competitors will not develop new products or improve their
existing products which, when combined with their existing market presence,
would make the Company's products obsolete or unmarketable. Any such development
would have a material adverse effect on the Company. There also can be no
assurance that the Company will be able to penetrate the wet processing
equipment market and convince semiconductor or other manufacturers to install
the Company's systems either directly or through retrofitting in place of
existing equipment. Additional competition for the Company's products also
currently comes from a large number of small companies making cleaning, rinsing,
and drying equipment which is less expensive than the Company's products.
Because the Company's products sell for significantly higher prices than such
products, the Company may not be able to compete effectively against them
without lowering its prices.

            The Company also expects that competition may arise from new
competitors and from new technological approaches adopted by new and existing
competitors. Because of the increasing focus on yield management in the
semiconductor manufacturing industry, equipment manufacturers are likely to put
an increased emphasis on contaminant reduction. Thus, competitive technologies
or new manufacturing techniques may be developed which could make the Company's
products obsolete, thereby materially





                                       12
<PAGE>   13

adversely affecting the Company. If the Company is unable to respond to the
challenges of competition, including changes in cleaning, rinsing, and drying or
semiconductor or other manufacturing processes, there can be no assurance that
the Company would be able to achieve or maintain profitability at a level
required to support its survival or growth.

RELIANCE ON SINGLE PRODUCT FAMILY

            The Company anticipates that the substantial majority of its future
revenues will come from sales of its cleaning, rinsing, and drying systems.
Should the demand for, or pricing of, the Company's products decline due to
increased competitive pressure, the introduction of superior systems or
processes, changes in the semiconductor, magnetic or optical disk, flat panel
display or photo-mask industries or other factors, the Company's business,
financial condition and results of operations would be materially adversely
affected. The ability of the Company to diversify its operations through the
introduction and sale of new products and broader acceptance of its cleaning,
rinsing, and drying systems is dependent on the success of the Company's
continuing research, product development and engineering activities, as well as
its marketing efforts. No assurance can be given that the Company will be able
to develop, acquire, introduce or market new products in a timely or
cost-effective manner or that any new products or improvements will achieve
market acceptance or result in acceptable margins. Accordingly, the Company will
be dependent on overall market acceptance of its products.

PART II.    OTHER INFORMATION

ITEM 1.     LEGAL PROCEEDINGS

            CFM Technologies, Inc. and CFMT, Inc. (collectively "CFM") filed a
complaint against the Company in United States District Court for the District
of Delaware in September 1995. The complaint alleged that the drying process
incorporated in certain of the Company's products infringes a patent held by
CFM. On October 14, 1997, a federal court for the District of Delaware ruled in
favor of the defendant, YieldUP International Corporation. In a written opinion
granting summary judgment for YieldUP, the United States District Court held
that CFM had failed to produce evidence on three separate elements of the patent
claim. To establish infringement, evidence of all three elements was required.
However, there can be no assurance that this judgment will not be overturned
should there be an appeal by CFM. A loss, if any, resulting from an unfavorable
adjudication, cannot presently be estimated. Accordingly, no provision for any
liability that may result upon adjudication has been made in the accompanying
condensed financial statements.

ITEM 2.     CHANGES IN SECURITIES

            On March 30, 1998, the Company completed an equity financing in a
private placement of Series A Convertible Preferred Stock (Series A Shares) with
net proceeds to the Company of approximately $5.9 million. The Company, subject
to certain conditions, may exercise a put option for up to an additional $6
million of Series A Shares and the investors, subject to certain conditions, may
exercise a call option for up to an additional $6 million of Series A Shares.
The Company has filed a registration statement that has not yet become effective
for the resale of the shares of the Company's Common Stock that may be acquired
on conversion of the Series A Shares.

CONVERSION

            The Series A Shares are convertible into shares of Common Stock at
the election of the holder of such Series A Shares, at a price (the "Conversion
Rate") equal to the lower of the market price at the original date of issuance
of such share (the "Fixed Conversion Price") or the lowest market price during
the 20 consecutive days immediately preceding the date a holder of Series A
Shares delivers notice of his election to convert such shares. "Market price" is
generally determined by the closing price for the Registrant's Common Stock on
the applicable date.

Except upon the occurrence of certain events, the Investor(s) may convert, in
aggregate, only up to a maximum of a specified percentage of the Series A Shares
according to the following schedule:


<TABLE>
<CAPTION>
                          Days from                % of Shares
                          Closing                  Convertible
                      ---------------              -----------
<S>                                                <C>
                      1 through 90                       0
                      91 through 135                    20
                      136 through 180                   40
                      181 through 225                   60
                      226 through 270                   80
                      271 through term                 100
</TABLE>

Subject to certain exceptions, any Series A Shares outstanding three years after
the date such shares were initially issued will automatically convert into
shares of the Registrant's Common Stock at the then applicable Conversion Rate.




                                       14
<PAGE>   15

POTENTIAL DILUTIVE EFFECTIVE OF CONVERSION OF SERIES A PREFERRED STOCK

            The number of shares of Common Stock which may be issued upon
conversion of the Series A Shares is dependent upon the trading price of the
Company's Common Stock at the time of conversion. To the extent that the
trading price of the Common Stock is lower than 10.8625 per share at the time
of any conversion of the currently outstanding Series A Shares, the number of
shares of Common Stock issuable upon such conversion will increase with
resulting dilution to the holders of the Company's Common Stock. There is no
minimum conversion price and thus no maximum number of shares of Common Stock
into which the Series A Shares may be converted. The Series A Shares also have
a cumulative annual dividend of 5% payable in shares of Common Stock upon
conversion. The Purchase Agreement also provides for the issuance of additional
Series A Shares, subject to certain conditions. Issuance of such additional
Series A Shares will result in additional dilution to the holders of the Common
Stock.


ADJUSTMENTS TO CONVERSION RATE

            The Conversion Rate is subject to proportional adjustment upon any
stock split, stock dividend or other similar change to the capital stock of the
Registrant as well other adjustments upon the issuance, or deemed issuance, of
other shares of Common Stock at a price below the then effective Fixed
Conversion Price.

MANDATORY CONVERSION

             Under certain circumstances after the Registrant publicly discloses
a Change of Control Transaction, as defined in the Certificate of Designation,
the Registrant shall have the right to require that all of the outstanding
Series A Shares be converted to Common Stock.

REDEMPTION

The holders of Series A Shares have a right to require the Registrant to redeem
the Series A Shares upon the occurrence of certain events, including a Major
Transaction, or a Triggering Event, as each is defined in the Certificate of
Designation.


LIMITATIONS ON CONVERSION AND EXERCISE

            The Purchase Agreement provides that the number of shares of the
Registrant's Common Stock issuable upon conversion of the Series A Shares cannot
exceed 20% of the outstanding shares of the Registrant's Common Stock without
the approval of the stockholders of the Registrant. Likewise, the number of
shares of the Registrant's Common Stock issuable from to time to any single
Investor cannot exceed 4.99% or more of the Registrant's outstanding Common
Stock.


EFFECT ON RIGHTS OF EXISTING SECURITY HOLDERS

            There is no change to the rights, preferences or privileges of the
holders of the Registrant's Common Stock as a result of the transactions which
are the subject of the Purchase Agreement. However, in addition to the dilutive
impact of the issuance of additional shares of capital stock, the Series A
Shares have a liquidation preference which entitles the holders thereof to
receive payment upon any dissolution or liquidation of the Registrant in
preference to the holders of Common Stock. The amount of such preference is
equal to $12,000 plus an amount equal to the product of (.05)(N/365)($12,000)
for each of the Series A Shares where "N" is the number of days since the
initial issuance of such shares.

            On March 4, 1998, the Company issued a warrant to purchase 2,439
shares of its Common Stock to a commercial lender in connection with the
establishment of a line of credit. The warrant has an exercise price of $10.25
per share. On February 19, 1997, the Company issued 5,149 shares of Common
Stock upon the exercise of a warrant issued to a commercial lender in
connection with the establishment of a line of credit.
