                                INTRODUCTORY NOTE

        As reported in the press release in the report of BioLase Technology,
Inc. (the "Company") on Form 8-K filed August 14, 2003, the Company decided to
seek guidance from the Securities and Exchange Commission ("SEC") regarding the
accounting effect of certain language in the Company's purchase order forms. To
protect the Company's right to payment, the forms stated that title to goods
transferred to the customer upon receipt of full payment. Legally, this language
only provided a lien to secure payment.

        One of the revenue recognition criteria of Staff Accounting Bulletin No.
101 ("SAB 101"), Revenue Recognition in Financial Statements, requires the
transfer of title and the risks and rewards of ownership to the customer.
Historically, the Company recognized revenue when it received a purchase order,
goods were shipped and the other criteria for revenue recognition were met. As
reported in the press release in the Company's report on Form 8-K filed August
29, 2003, the Company is amending previously filed financial statements for all
periods subsequent to the effective date of SAB 101 to recognize revenue with
respect to domestic customers upon receipt of full payment. It was determined
that under an interpretation of SAB 101 the language in the Company's purchase
order regarding title prevents revenue from being recognized until full payment
is received. In addition, the Company is amending its previously filed financial
statements to recognize revenue with respect to direct European customers upon
installation, which is when the customer is obligated to pay, and not at the
time of shipment.

        The purpose of this Amendment No. 1 on Form 10-Q/A is to restate the
Company's consolidated financial statements as of September 30, 2002 and
December 31, 2001, and for each of the three and nine months ended September 30,
2002 and 2001.

        The Company is filing amended Quarterly Reports on Form 10-Q/A to
restate the Company's financial statements for the periods ended March 31, 2002
through March 31, 2003. The Company is also filing its Quarterly Report on Form
10-Q for the period ended June 30, 2003, which was delayed while the Company
sought SEC guidance on the revenue recognition issue. The Company will also file
an amendment to its Current Report on Form 8-K/A relating to its acquisition of
the American Dental Laser product line of American Medical Technologies, which
was initially filed on June 4, 2003, and subsequently amended on June 23, 2003
and August 1, 2003.

        The Company did not amend its annual reports on Form 10-K for years
prior to 2002 because financial statements for 2001 and 2000 are contained in
the amended Form 10-K/A. Similarly, the Company did not amend its Quarterly
Reports on the amended Form 10-Q for the quarterly periods in 2001 because
financial statements for those periods are contained in the Forms 10-Q/A the
Company is filing for 2002. You should not rely on the financial statements and
other financial information contained in the Company's Forms 10-K and 10-Q for
periods prior to 2002. You should also not rely on any financial statements or
financial information relating to the periods being restated contained in the
Company's Forms 8-K that were filed before the amended Form 10-K/A.

        This Form 10-Q/A only reflects the effects of the restatement and does
not otherwise reflect events occurring after the filing of the original
Quarterly Report on Form 10-Q or otherwise modify or update those disclosures.

BIOLASE TECHNOLOGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

NOTE 1 - BASIS OF PRESENTATION

        The unaudited consolidated financial statements included herein have
been prepared on a basis consistent with the restated December 31, 2001 audited
consolidated financial statements and include all material adjustments,
consisting of normal recurring adjustments, necessary to fairly present the
information set forth therein. These unaudited interim consolidated financial
statements do not include all the footnotes, presentations and disclosures
normally required by generally accepted accounting principles for complete
financial statements. These financial statements should be read in conjunction
with the restated audited consolidated financial statements for the year ended
December 31, 2001 and notes thereto included in our Annual Report on Form 10-K/A
for the year ended December 31, 2002, as amended by Amendment No.1 filed with
the Securities and Exchange Commission ("SEC") on September 16, 2003.

        The consolidated financial statements include the accounts of BioLase
Technology, Inc. and its two wholly-owned subsidiaries: Societe Endo Technic,
which is inactive and which we intend to dissolve, and BIOLASE Europe GmbH, a
foreign subsidiary incorporated in Germany in December 2001. We have eliminated
all material intercompany transactions and balances in the accompanying
financial statements.

        The preparation of financial statements in conformity with GAAP requires
us to make estimates and assumptions that affect the amounts reported in the
financial statements and the accompanying notes. Due to the inherent uncertainty
involved in making estimates, actual results reported in future periods may
differ materially from those estimates.

        The results of operations for the nine months ended September 30, 2002
are not necessarily indicative of the results to be expected for the full fiscal
year.

        Certain amounts in the prior period consolidated financial statements
have been reclassified to be consistent with the current period presentation.

NOTE 2 - RESTATEMENT OF FINANCIAL STATEMENTS

        Staff Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in
Financial Statements, requires the transfer of title and the risks and rewards
of ownership to the customer prior to the recognition of revenue. We originally
prepared our financial statements on the basis that this transfer of title
occurred upon shipment. Subsequent to the issuance of our consolidated financial
statements as of and for the year ended December 31, 2002, it was determined,
with respect to sales to domestic customers, that title transferred upon receipt
of full payment, due to a clause in our purchase orders. As a result, we have
restated our consolidated financial statements as of September 30, 2002 and
December 31, 2001 and the three and nine month periods ended September 30, 2002
and 2001 to defer revenue upon shipment and to recognize it upon receipt of full
payment for our domestic customers. It was also determined that revenue
recognition for products shipped directly to customers in Europe, which we
commenced in 2002, is appropriate at the time of installation, which is when the
customer is obligated to pay, and not at the time of shipment as recognized in
the previously filed financial statements. In conjunction with these revisions,
we have deferred the revenue, the related cost of inventory and related sales
commissions. In addition, there was an error in our diluted net income per share
for the nine months ended September 30, 2002 that resulted in a reduction of
$0.01.

        As a result of the restatement, our net revenue for the three and nine
months ended September 30, 2002 decreased by $455,000 and $570,000,
respectively, our gross profit decreased by $435,000 and $450,000, respectively,
and our net income decreased by $390,000 ($0.02 per fully diluted share) and
$394,000 ($0.01 per fully diluted share), respectively. For the three months and
nine months ended September 30, 2001, our net revenue decreased by $706,000 and
$768,000, respectively, and our gross profit decreased by $429,000 and $472,000,
respectively. Our net income of $102,000 for the three months ended September
30, 2001 was converted to net loss of $256,000 (a difference of $358,000 or
$0.02 per fully diluted share) and our net loss for the nine months ended
September 30, 2001 increased by $409,000 ($0.02 per fully diluted share).

NOTE 4 - PROPERTY, PLANT AND EQUIPMENT

        In January 2002, our wholly owned subsidiary, BIOLASE Europe, purchased
a production facility in Germany with ten employees. We have recorded the
transaction at the nominal or stated purchase price of $1,000,000 with the cost
reflected in property, plant and equipment and the amount payable reflected in
long-term debt. The purchase price could be less depending on the outcome of
negotiations with a third party for that party to pay all or a portion of the
first installment in exchange for certain rights that we would grant to the
third party. The scheduled amount of the first installment is expected to be
between $300,000 and $500,000. If we do not reach agreement with the third
party, the stated purchase price and the first installment will be reduced from
$1,000,000 to $850,000 and $300,000 to $150,000, respectively. Due to the
ongoing negotiations with the third party, the due date of the first installment
has been extended from October 31, 2002 to September 30, 2003. There is no
assurance that we will be able to reach an agreement with the third party to pay
any or all of the first installment. The final purchase price is payable in
Euros at the conversion rate in effect on the acquisition date. In connection
with this transaction, we entered into a forward contract to purchase
approximately $700,000 of Euros at an exchange rate of 0.8591. Regardless of the
amount of the initial installment, we are obligated to pay an additional
$500,000 by April 1, 2003 and the balance of the purchase price, if any, by
December 1, 2003.

NOTE 5 - LINE OF CREDIT

        At September 30, 2002, we had $1,792,000 outstanding under a revolving
credit agreement with a bank. The agreement provides for borrowings up to
$1,800,000 for financing inventories and is secured by substantially all of our
accounts receivable and inventories. The interest rate is based upon LIBOR plus
0.5% at the time of any borrowings. At September 30, 2002, the interest rate on
the outstanding balance was 2.3%. The effective interest rate for the quarter
ended September 30, 2002 was 1.9%, including the amortization of the fair value
of stock issued in connection with extending our line of credit. In June 2002,
the expiration date of the credit agreement was extended from January 31, 2003
to July 31, 2003.

NOTE 6 - COMMITMENTS AND CONTINGENCIES

        In March 2001, we entered into a sale-leaseback transaction in which we
sold and leased back our manufacturing facility in San Clemente, California. The
result of the sale was a $316,000 gain, which has been deferred and is being
amortized over the four years remaining under the lease term. The related lease
is being accounted for as an operating lease.

        We also lease certain office equipment under operating lease
arrangements. Future minimum rental commitments under operating leases as of
September 30, 2002 for each of the years ending December 31 are as follows:

        On October 31, 2002, the Company filed a lawsuit in the U.S. District
Court for the Central District of California, Southern Division, against
American Medical Technologies, Inc. ("AMT"). In the lawsuit, the Company alleges
that AMT is infringing certain patents owned by the Company, which relate to the
use of laser technology in the medical and dental fields. The Company's claims
arise out of AMT's offer to sell and sale in the United States of a dental
device that uses laser technology. In the lawsuit, the Company is seeking an
award of monetary damages and injunctive relief against AMT. While the Company
believes that the case is meritorious, there is no assurance that the Company
will achieve a favorable outcome.

        From time to time, we are involved in legal proceedings incidental to
our business. We believe that pending actions, individually and in the
aggregate, will not have a material adverse effect on our financial condition,
results of operations or cash flows, and that adequate provision has been made
for the resolution of such actions and proceedings.

NOTE 7 - EARNINGS PER SHARE

        We compute basic earnings (loss) per share by dividing the net income
(loss) attributable to common stockholders by the weighted average number of
shares outstanding. We compute diluted earnings per share by dividing net income
by the weighted average number of shares outstanding including stock options and
warrants. Stock options totaling 304,000 and 287,000 were not included in the
diluted earnings per share amounts for the three and nine months ended September
30, 2002, respectively, and 880,000 were not included in the nine months ended
September 30, 2001, as their effect would have been anti-dilutive.

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

CAUTIONARY STATEMENT WITH RESPECT TO FORWARD-LOOKING INFORMATION

        You should read the following discussion and analysis in conjunction
with our Unaudited Consolidated Financial Statements and related Notes thereto
contained elsewhere in this Report. The information contained in this Report is
not a complete description of our business or the risks associated with an
investment in our common stock. We urge you to carefully review and consider the
various disclosures made by us in this Report and in our other reports filed
with the Securities and Exchange Commission, including our Annual Report on Form
10-K/A for the year ended December 31, 2002, and our subsequent reports on Forms
10-Q/A and other filings that discuss our business in greater detail. This
Report contains forward-looking statements that can often be identified by words
such as "anticipates," "expects," "intends," "plans," "believes," "seeks,"
"estimates," "may," "will," "should," "would," "potential," "continue," and
variations of these words or similar expressions. In addition, any statements
that refer to expectations, projections or other characterizations of future
events or circumstances, including any underlying assumptions, are
forward-looking statements. Examples of these forward-looking statements
include, but are not limited to, statements concerning the application of our
technology, the potential of our market and our position in it, our
manufacturing capacity, estimates concerning asset valuation and loss
contingencies and expectations concerning future costs and cash flow, and our
ability to successfully finance our business or replace existing loans. These
forward-looking statements are based on our current expectations, estimates and
projections about our industry, and reflect our beliefs and certain assumptions
made by us. These statements speak only as of the date of this Report and are
based upon the information available to us at this time. Such information is
subject to change, and we will not necessarily inform you of such changes. These
forward-looking statements are not guarantees of future performance and are
subject to risks, uncertainties and assumptions that are difficult to predict.
Therefore, our actual results could differ materially and adversely from those
expressed in any forward-looking statements as a result of various factors, some
of which are set forth in "Risk Factors," below. We undertake no obligation to
revise or update publicly any forward-looking statements for any reason.

RESTATEMENT OF FINANCIAL STATEMENTS

        Staff Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in
Financial Statements, requires the transfer of title and the risks and rewards
of ownership to the customer prior to the recognition of revenue. We originally
prepared our financial statements on the basis that this transfer of title
occurred upon shipment. Subsequent to the issuance of our consolidated financial
statements as of and for the year ended December 31, 2002, it was determined,
with respect to sales to domestic customers, that title transferred upon receipt
of full payment, due to a clause in our purchase orders. As a result, we have
restated our consolidated financial statements as of September 30, 2002 and
December 31, 2001 and the three and nine month periods ended September 30, 2002
and 2001 to defer revenue upon shipment and to recognize it upon receipt of full
payment for our domestic customers. It was also determined that revenue
recognition for products shipped directly to customers in Europe, which we
commenced in 2002, is appropriate at the time of installation, which is when the
customer is obligated to pay, and not at the time of shipment as recognized in
the previously filed financial statements. In conjunction with these revisions,
we have deferred the revenue, the related cost of inventory and related sales
commissions. In addition, there was an error in our diluted net income per share
for the nine months ended September 30, 2002 that resulted in a reduction of
$0.01.

        As a result of the restatement, our net revenue for the three and nine
months ended September 30, 2002 decreased by $455,000 and $570,000,
respectively, our gross profit decreased by $435,000 and $450,000, respectively,
and our net income decreased by $390,000 ($0.02 per fully diluted share) and
$394,000 ($0.01 per fully diluted share), respectively. For the three months and
nine months ended September 30, 2001, our net revenue decreased by $706,000 and
$768,000, respectively, and our gross profit decreased by $429,000 and $472,000,
respectively. Our net income of $102,000 for the three months ended September
30, 2001 was converted to net loss of $256,000 (a difference of $358,000 or
$0.02 per fully diluted share) and our net loss for the nine months ended
September 30, 2001 increased by $409,000 ($0.02 per fully diluted share).

OVERVIEW

        BioLase Technology, Inc. is a medical technology company that designs,
develops, manufactures and markets advanced dental, cosmetic and surgical
laser-based products. We currently market two primary products. The
Waterlase(TM) system, utilizing our patented Hydrokinetic(R) technology of
combining water and laser energy, is a device which can be applied to the
treatment of both hard and soft dental tissues. The LaserSmile(TM) system
incorporates a diode semiconductor laser for a broad range of soft tissue and
cosmetic procedures. Most of our sales are derived from the shipment of the
Waterlase system. Sales of the LaserSmile system commenced in the third quarter
of 2001; prior to that time the LaserSmile system was sold as the Twilite soft
tissue laser, which did not include the teeth whitening capability.

        In January 2002, we received from the United States Food and Drug
Administration Section 510(k) clearance for the application of our Hydrokinetic
technology to perform complete root canal therapy (EndoLase(TM)). In February
2002, we received Food and Drug Administration Section 510(k) clearance for the
use of Hydrokinetic technology to cut oral bone tissue (OsseoLase(TM)). We
believe these clearances substantially broaden the application of our technology
within the dental market.

                                       13



        We have patents and have received clearances from the FDA for
applications in markets other than dentistry, such as dermatology. However, we
currently plan to focus our business on the dental market because of what we
believe to be both the significant potential of the dental market and our
leading position in that market.

        In January 2002, we acquired a production facility in Germany to
strengthen our international sales plan in Europe and neighboring regions. In
our estimate, this transaction both significantly increased our overall
manufacturing capacity and provided us with an improved ability to service
European sales.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

        Our discussion and analysis of our financial condition and results of
operations are based upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires us to make
estimates and judgments that affect the reported amount of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amount of revenues and expenses for
each period.

        The following represents a summary of our critical accounting policies,
defined as those policies that we believe are: (i) the most important to the
portrayal of our financial condition and results of operations, and (ii) that
require our most difficult, subjective or complex judgments, often as a result
of the need to make estimates about the effects of matters that are inherently
uncertain.

        Revenue Recognition. We recognize revenue in accordance with SEC Staff
Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, or SAB
101, as amended by SAB 101A and 101B. SAB 101 requires that four basic criteria
must be met before revenue can be recognized:

        .     persuasive evidence of an arrangement exists;

        .     delivery has occurred and title and the risks and rewards of
              ownership have been transferred to our customer or services have
              been rendered;

        .     the price is fixed and determinable; and

        .     collectibility is reasonably assured.

        Assuming that all of the above criteria have been met, we record revenue
for domestic sales when we receive payment in full, due to a clause in our
purchase order that states title transfers upon payment in full; we record
revenue for international direct sales when the product is installed, which is
when the customer is obligated to pay and we record revenue for sales to
distributors upon delivery.

        Valuation of Accounts Receivable. We maintain an allowance for
uncollectible accounts receivable to estimate the risk of extending credit to
customers. The allowance is estimated based on customer compliance with credit
terms, the financial condition of the customer and collection history where
applicable. Additional allowances could be required if the financial condition
of our customers were to be impaired beyond our estimates.

        Valuation of Inventory. Inventory is valued at the lower of cost
(estimated using the first-in, first-out method) or market. We periodically
evaluate the carrying value of inventories and maintain an allowance for
obsolescence to adjust the carrying value as necessary to the lower of cost or
market. The allowance is based on physical and technical functionality as well
as other factors affecting the recoverability of the asset through future sales.
Unfavorable changes in estimates of obsolete inventory would result in an
increase in the allowance and a decrease in gross profit.

        Valuation of Long-Lived Assets. Property, plant and equipment,
intangible and certain other long-lived assets are amortized over their useful
lives. Useful lives are based on our estimate of the period that the assets will
generate revenue or otherwise productively support our business goals.
Long-lived assets are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable through future business operations. In our estimate, no provision
for impairment is currently required on any of our long-lived assets.

                                       14



        Warranty Cost. Products sold directly to end-users are covered by a
warranty against defects in material and workmanship for a period of one year.
Products sold internationally to distributors are covered by a warranty on parts
for up to fourteen months with additional coverage on certain components for up
to two years. We accrue a warranty reserve to estimate the risk of incurring
costs to provide warranty services. The accrual is based on our historical
experience and our expectation of future conditions. An increase in warranty
claims or in the costs associated with servicing those claims would result in an
increase in the accrual and a decrease in gross profit.

        Litigation and Other Contingencies. We regularly evaluate our exposure
to threatened or pending litigation and other business contingencies. Because of
the uncertainties related to the amount of loss from litigation and other
business contingencies, the recording of losses relating to such exposures
requires significant judgment about the potential range of outcomes. As
additional information about current or future litigation or other contingencies
becomes available, we will assess whether such information warrants the
recording of additional expense relating to contingencies. To be recorded as
expense, a loss contingency must be both probable and measurable. If a loss
contingency is material but is not both probable and estimable, we will disclose
it in notes to the financial statements.

RESULTS OF OPERATIONS

        In the following discussion of the results of operations, unless
otherwise noted, the three and nine month periods ended September 30, 2002 are
compared to the three and nine-month periods ended September 30, 2001.

        The following table sets forth certain statement of operations data
expressed as a percentage of net sales:

        Comparing the results of operations between the current year and the
corresponding periods in the prior year, the most significant change affecting
operating results is the increase in sales. Third quarter 2002 sales increased
73% over third quarter 2001 and nine month 2002 sales have increased 69% over
nine month 2001 sales.

        Net Sales. Net sales for the three months ended September 30, 2002 were
$6.9 million, an increase of $2.9 million as compared with net sales of $4.0
million for the three months ended September 30, 2001. Net sales for the nine
months ended September 30, 2002 were $19.1 million, an increase of $7.8 million
as compared with net sales of $11.3 million for the nine months ended September
30, 2001. The increase in both the three and nine month periods

                                       15



was resulted from increased number of units sold of our Waterlase and LaserSmile
systems. Average selling price for these products in the periods being compared
has not varied significantly.

        International sales increased in the third quarter of 2002 to 26% of
total sales compared to 19% in the same period last year. Year-to-date
international sales have increased to 20% of total sales from 18% in the same
period last year. Most of our international sales are made through distributors.
In the three months ended June 30, 2002, we began making direct sales to
dentists in Germany with the support of our current distributor there, as well
as continuing to sell through distributor channels in Germany and elsewhere. In
connection with increased credit uncertainty related to these direct sales, we
have increased our allowance on accounts receivable from $100,000 at June 30,
2002 to $173,000 at September 30, 2002.

        Gross Profit. Gross profit for the three months ended September 30, 2002
was $4.1 million or 60% of net sales, an increase of $1.7 million or 73% from
gross profit of $2.4 million or 60% of net sales for the three months ended
September 30, 2001. Gross profit for the nine months ended September 30, 2002
was $11.6 million or 60% of net sales, an increase of $4.9 million or 74% from
gross profit of $6.7 million or 59% of net sales for the nine months ended
September 30, 2001. The increase in gross profit is primarily attributable to
leveraging the increase in net sales against fixed and partially fixed
manufacturing costs, reflecting better absorption of fixed manufacturing costs.
To a lesser extent, the increase in gross profit is also due to increased
manufacturing efficiencies and design changes, which have reduced the cost of
materials. These efficiencies and cost savings have been partially offset by the
start-up costs for our German production and service facility and the addition
of production resources to support anticipated sales growth.

        Other Income. Other income was due to the gain on sale of assets for the
three and nine months ended September 30, 2002 of $15,000 and $47,000,
respectively, related to the sale and leaseback of our manufacturing facility in
San Clemente, California in March 2001. This sale resulted in a gain of
$316,000, which will be recognized over the remaining term of the lease expiring
in 2006.

        Operating Expenses. Operating expenses for the three and nine months
ended September 30, 2002 were 54% and 55% of net sales, compared to 67% and 69%
in the comparable periods of the prior year. Approximately 80% of the increase
in operating expenses for the three and nine months ended September 30, 2002 are
sales and marketing costs that have been incurred to generate the increase in
net sales.

        Sales and marketing expenses generally includes salaries and commissions
for our direct sales force, advertising costs and expenses related to trade
shows, conventions and seminars. Sales and marketing expense for the three
months ended September 30, 2002 was $2.6 million or 38% of net sales, an
increase of $879,000 or 50%, as compared with sales and marketing expense for
the three months ended September 30, 2001 of $1.7 million or 44% of net sales.
Sales and marketing expense for the nine months ended September 30, 2002 was
$7.3 million or 38% of net sales, an increase of $2.0 million or 39%, as
compared with sales and marketing expense for the nine months ended September
30, 2001 of $5.2 million or 46% of net sales. The increase in absolute dollars
was primarily due to higher commission expense related to the increased sales
and additional sales personnel in the United States, and to a lesser extent, the
expansion of the scope of our nationwide seminar marketing program in 2002.

        General and administrative expenses generally include the salaries of
administrative personnel as well as professional and regulatory fees. General
and administrative expense for the three months ended September 30, 2002 was
$739,000 or 11% of net sales, an increase of $167,000 or 29%, as compared with
general and administrative expense for the three months ended September 30, 2001
of $572,000 or 14% of net sales. General and administrative expense for the nine
months ended September 30, 2002 was $2.1 million or 11% of net sales, an
increase of $537,000 or 35%, as compared with general and administrative expense
for the nine months ended September 30, 2001 of $1.5 million or 14% of net
sales. The increase in absolute dollars for both the three and nine months was
principally due to cumulative increases in the infrastructure needed to support
the growth of our business including increases in the cost of regulatory
compliance, administrative costs associated with the operations of BIOLASE
Europe and increases in the allocated costs of insurance.

        Engineering and development expenses generally include engineering
personnel salaries, prototype supplies and contract services. Engineering and
development expense for the three months ended September 30, 2002 was $360,000
or 5% of net sales, a slight increase of $20,000 or 6%, as compared with
engineering and development expense for the three months ended September 30,
2001 of $340,000 or 9% of net sales. Engineering and

                                       16



development expense for the nine months ended September 30, 2002 was $1.1
million or 6% of net sales, an increase of $84,000 or 8%, as compared with
engineering and development expense for the nine months ended September 30, 2001
of $1.1 million or 9% of net sales. The increase in absolute dollars for the
nine months ended September 30, 2002 is prototype material costs and consulting
fees related to product development. The change in research and development
expense as a percent of net sales reflects the larger sales base and normal
fluctuations in the scope of current research and development projects.

        In September we renewed our insurance policies for the period October 1,
2002 to September 30, 2003 for a total premium increase of $245,000, driven both
by adverse pricing conditions in the insurance market and by the expected growth
in our sales. The premium increase will raise operating expenses as it is
amortized to expense during the coverage period.

        Unrealized Gain on Forward Exchange Contract. In the nine months ended
September 30, 2002, we recognized an unrealized gain on forward contracts of
$102,000, due to the increase in the fair market value of our forward exchange
contract as described more fully in Part I, Item 3 of this Report.

        Interest Income/Interest Expense. Interest income primarily relates to
interest earned on our cash balances, and interest expense primarily relates to
interest expense on our line of credit and our prior mortgage on the San
Clemente facility. Interest income for the three and nine months ended September
30, 2002 was $6,000 and $13,000, a decrease of 40% and 44% from interest income
of $10,000 and $23,000 in the comparable periods of the prior year, due
principally to lower interest rates in 2002. Interest expense increased $12,000
or 55% from $22,000 to $34,000 for the three months ended September 30, 2002
compared to the same period last year as the result of the amortization of loan
guarantee fees to interest expense over the renewal term of our line of credit
in 2002. Interest expense decreased by $31,000 or 24% from to $100,000 for the
nine months ended September 30, 2002, which reflects the repayment of the
mortgage on our San Clemente facility upon its sale in March 2001 as well as
lower interest rates on our line of credit in 2002

        Provision for Income Tax. No provision for income tax was recognized for
the three and nine-month periods ended September 30, 2002 due to the
availability of net operating loss carry forwards. No income tax benefit was
recognized in the three and nine-month periods ended September 30, 2001 as there
was no assurance that the benefit of the net operating loss carry forwards would
be realized. As of December 31, 2001, we had net operating loss carry forwards
for federal and state purposes of approximately $37.8 million and $6.4 million,
respectively, which began expiring in 2001.

LIQUIDITY AND CAPITAL RESOURCES

        At September 30, 2002, we had $1.6 million in net working capital as
compared to $201,000 at December 31, 2001. Our principal source of liquidity at
September 30, 2002 consisted of our cash balance of $2.9 million. Historically,
we have financed the development of our products and our operations principally
through the private placement of common stock and the exercise of stock options
and warrants, though we have generated cash from net income excluding the
effects of changes in working capital, in each of the last five quarters. For
the nine months ended September 30, 2002, from December 1, 2002 to June 30, 2003
our primary sources of cash were from net income of $1.3 million, and the
exercise of stock options and warrants of $762,000. These sources of cash were
offset by increases in accounts receivable and inventory of $1.9 million, other
working capital items and investments in property and equipment of $335,000. The
net effect on cash of operating, investing and financing transactions for the
nine months ended September 30, 2002 was an increase of $250,000. For further
details see the Consolidated Statements of Cash Flows included in this Form
10-Q/A.

        Accounts receivable, net increased 69% to $3.7 million at September 30,
2002 from $2.2 million at December 31, 2001. This increase was primarily due to
the higher sales volume experienced in the third quarter of 2002. Inventories,
net increased 24% to $2.3 million at September 30, 2002 from $1.9 million at
December 31, 2001. This increase was primarily due to increased production
estimates to meet expected 2002 sales demand.

        In June 2002, we extended the expiration date of warrants to purchase
522,500 shares of common stock from September 30, 2002 to June 30, 2003. These
warrants have an exercise price of $2.50 and were issued in connection with a
private placement in 2000. In June 2002, we also extended the expiration date of
warrants to

                                       17



purchase 50,000 shares of common stock from December 1, 2002 to June 30, 2003.
These warrants have an exercise price of $3.00 per share and were issued in
connection with previous annual extensions of our credit facility.

        At September 30, 2002, we had $1.8 million outstanding under a $1.8
million revolving credit facility with a bank, the same amount that was
outstanding at December 31, 2001. In June 2002, the expiration date on this
credit facility was extended from January 31, 2003 to July 31, 2003, at which
point we will be required to pay any remaining balance, refinance or replace the
credit facility. We cannot assure you that we will be able to renew this
facility in a timely manner, on acceptable terms or at all. The credit facility
is collateralized by all of our accounts receivable and inventories.

        In connection with the acquisition of our production facility in
Germany, as discussed in Note 4 to the Unaudited Consolidated Financial
Statements, BIOLASE Europe incurred a liability of $1,000,000 payable in Euros
at the conversion rate of 0.8591. If we are not able to reach an agreement with
a third party to pay all or part of the scheduled first installment of between
$300,000 and $500,000, we will be required to make the initial installment of
$150,000 (Euros 174,601) on September 30, 2003. We are required to make a
payment of $500,000 (Euros 582,004) by April 1, 2003 and the balance, if any, by
December 1, 2003. We are considering obtaining a long-term, secured real estate
financing to refinance this debt as it matures, but we cannot assure you that
such financing will be available in a timely manner, on acceptable terms or at
all.

        We had no material commitments for capital expenditures as of September
30, 2002.

        Our liquidity and cash requirements fluctuate based on the timing and
extent of a number of factors. For instance, during periods of recent sales
growth, net changes in our assets and liabilities generally have represented a
use of cash because we have incurred costs and expended cash in advance of
receiving cash from our customers. We believe that our current cash balances,
cash expected to be generated from our operations, together with additional cash
expected to be received through the exercise of warrants and stock options will
be adequate to meet our debt service requirements and sustain our operations for
at least the next twelve months. Should we require further capital resources in
the next twelve months, we may address such requirement through the refinancing
of debt and/or the sale of equity securities. If such additional debt or equity
is needed, we cannot assure you that we would be able to obtain such additional
capital resources in a timely manner, on acceptable terms, or at all. If we are
unable to raise additional funds, we may have to defer the creation or
satisfaction of various commitments, defer the introduction of various products
or entry into various markets, or otherwise scale back our operations. If we
were unable to raise such additional capital or defer certain costs as described
above, such inability would have an adverse effect on our financial position,
results of operations and cash flows.

RISK FACTORS

        Our business is subject to a number of risks, some of which are
discussed below. Other risks are presented elsewhere in this report and in our
other filings with the Securities and Exchange Commission. Before deciding to
invest in our company or to maintain or increase your investment, you should
carefully consider the risks described below, in addition to the other
information contained in this report and in our other filings with the
Securities and Exchange Commission. The risks and uncertainties described below
are not the only ones facing our company. Additional risks and uncertainties not
presently known to us or that we currently deem immaterial may also affect our
business operations. If any of these risks actually occur, our business,
financial condition or results of operations could be seriously harmed. In that
event, the market price for our common stock could decline and you may lose all
or part of your investment.

Dentists and Physicians May Be Slow to Adopt Laser Technologies, Which Could
Limit the Market Acceptance of Our Products.

        Although our sales have increased year over year, our products represent
new technologies in the dental market and currently only represent a very small
portion of the dental and medical markets. Our future success will depend on our
ability to demonstrate to a broad spectrum of dentists and physicians the
potential cost and performance advantages of our laser systems over traditional
methods of treatment and, to a lesser extent, over competitive laser systems.
Dental practitioners may be slow to adopt new technologies on a widespread
basis. Factors that may inhibit mass adoption of laser technologies by dentists
and physicians include the cost of the products, concerns about the safety,
efficacy and reliability of lasers and the ability to obtain reimbursement of
laser procedures under health plans. Current economic pressure may make dentists
and physicians reluctant to purchase substantial capital equipment or invest in
new technologies. The failure of medical lasers to achieve broad market
acceptance would have an adverse effect on our business, financial condition and
results of operations. We cannot assure you that we will have sufficient
resources to continue to successfully market our products to achieve broad
market acceptance.

We Depend on a Limited Number of Suppliers and If We Cannot Secure Alternate
Suppliers, the Amount of Sales in Any Period Could Be Adversely Affected.

        We purchase certain materials and components included in our products
from a limited group of qualified suppliers, and we do not have long-term supply
contracts with any of our key suppliers. Our growth and ability to meet customer
demand depends in part on our ability to obtain timely deliveries of materials
and components in acceptable quality from our suppliers. Certain components of
our products are currently available only from a single source or limited
sources, particularly specialized components used in our lasers. Although we
believe that alternate sources of supply are available for most of our
single-sourced materials and components, a change in a single or limited source
supplier, or an inability to find an alternate supplier, would create
manufacturing delays, disrupt sales and cash flow, and harm our reputation, any
of which would adversely affect our business, financial condition and results of
operations.

Our Quarterly Sales and Operating Results May Fluctuate in Future Periods and We
May Fail to Meet Expectations, Which May Cause the Price of Our Common Stock to
Decline.

        Our quarterly sales and operating results have fluctuated and are likely
to continue to vary from quarter to quarter due to a number of factors, many of
which are not within our control. If quarterly sales or operating results fall
below the expectations of investors or securities analysts, the price of our
common stock could decline substantially. Factors that might cause quarterly
fluctuations in our sales and operating results include the factors described in
the subheadings below as well as:

        .     variation in demand for our products, including variation due to
              seasonality;

        .     our ability to develop, introduce, market and gain market
              acceptance of new products and product enhancements in a timely
              manner;

        .     our ability to control costs;

        .     the size, timing, rescheduling or cancellation of significant
              customer orders;

                                       19



        .     the introduction of new products by competitors;

        .     the availability and reliability of components used to manufacture
              our products;

        .     changes in our pricing policies or those of our suppliers and
              competitors, as well as increased price competition in general;

        .     the mix of our domestic and international sales, and the risks and
              uncertainties associated with our international business;

        .     costs associated with any future acquisitions of technologies and
              businesses; and

        .     general global economic and political conditions, including
              international conflicts and acts of terrorism.

        A significant amount of our sales in any quarter may consist of sales
through a single distributor. As a result, the timing of orders by distributors
may impact our quarter-to-quarter results. The loss of or a substantial
reduction in orders from distributors could seriously harm our business,
financial condition and results of operations. In addition, we have in the past
experienced fluctuations due to seasonality. Typical of the seasonality we have
experienced is that the first quarter is slower than average and the fourth
quarter is stronger than average due to the buying patterns of dental
professionals. Vacation schedules also have typically had an effect on sales in
the third quarter. Since many of our costs are fixed in the short term, if we
have a shortfall in sales, we may be unable to reduce our expenses quickly
enough to avoid losses. Due to all of the factors listed above and other risks,
some of which are discussed in this report, you should not rely on
quarter-to-quarter comparisons of our operating results as an indication of our
future performance.

We May Not Be Able to Secure Additional Financing to Meet Our Future Capital
Needs.

        Our secured line of credit expires on July 31, 2003. If we are unable to
renew or replace our secured line of credit at or before that time on acceptable
terms, or at all, and we are required to repay the secured line of credit,
absent sufficient cash flow from operations or the sale of securities, the
diversion of resources for that purpose would adversely affect our operations
and financial condition and our ability to achieve future growth in our net
sales, and our security may be at risk. In addition, during 2003, all of our
long-term debt related to the acquisition of our German production facility will
become due and payable. It is our intention to refinance that debt as it matures
with long-term secured real estate financing. There is no assurance that we will
be able to obtain such financing on acceptable terms, in a timely manner, or at
all. If we are unable to obtain such financing, we will have to repay our debt
obligations with cash, which may adversely affect our operations and financial
condition and our ability to achieve future growth in our net sales.

        Although we believe that we can generate sufficient cash flow from
sustained profitability to meet our future operating and capital needs, there is
no assurance that we will be able to do so. If we are unable to do so, we will
continue to be dependent on the availability of external financing to meet our
operating and capital needs, including the repayment of current debt
obligations. We may not be able to secure additional debt or equity financing on
terms acceptable to us, or at all, at the time when we need such funding. If we
do raise funds by issuing additional equity or convertible debt securities, the
ownership percentages of existing stockholders would be reduced, and the
securities that we issue may have rights, preferences or privileges senior to
those of the holders of our common stock or may be issued at a discount to the
current market price of our common stock which would result in dilution to our
existing stockholders. If we raise additional funds by issuing debt, we may be
subject to debt covenants, which could place limitations on our operations
including our ability to declare and pay dividends. Our inability to raise
additional funds on a timely basis would make it difficult for us to achieve our
business plan and would have a material adverse effect on our business,
financial condition and results of operations.

We Have Significant International Sales and Are Subject to Risks Associated with
Operating in International Markets.

        International sales comprise a significant portion of our net sales.
Political and economic conditions outside the United States could make it
difficult for us to increase our international sales or to operate abroad. In
addition, as part of our plan to grow sales internationally, in January 2002, we
purchased a production facility in Germany to manufacture and service devices to
be sold in Europe.

                                       20



        In the future, we intend to continue to pursue and expand our
international business activities. International operations, including our
production facility in Germany, are subject to many inherent risks, including:

    .   adverse changes in tariffs;

    .   political, social and economic instability and increased security
        concerns;

    .   fluctuations in currency exchange rates;

    .   longer collection periods and difficulties in collecting receivables
        from foreign entities;

    .   exposure to different legal standards;

    .   reduced protection for our intellectual property in some countries;

    .   burdens of complying with a variety of foreign laws;

    .   import and export license requirements and restrictions of the United
        States and each other country in which we operate;

    .   trade restrictions;

    .   the imposition of governmental controls;

    .   unexpected changes in regulatory or certification requirements;

    .   difficulties in staffing and managing international operations; and

    .   potentially adverse tax consequences and the complexities of foreign
        value added tax systems.

        We believe that international sales will continue to represent a
significant portion of our net sales, and that continued growth and
profitability may require further expansion of our international operations. A
substantial percentage of our international sales are denominated in the local
currency. As a result, an increase in the relative value of the dollar could
make our products more expensive and potentially less price competitive in
international markets. Other than a forward contract to offset the risk related
to the amounts payable for the German production facility, we do not currently
engage in any transactions as a hedge against risks of loss due to foreign
currency fluctuations. Any of these factors may adversely affect our future
international sales and, consequently, affect our business, financial condition
and operating results.

If We Are Not Successful in Generating and Increasing Sales from Our German
Production Facility, Our Business and Financial Condition May Be Materially
Adversely Affected.

        In January 2002, we made a significant investment in purchasing a German
production facility with ten employees. The production facility is a new
operation and we will face significant challenges in integrating it with our
existing business and operations, including but not limited to the following:

        .     entering into service agreements for devices sold in Europe;

        .     retraining existing employees in our operations, and hiring
              additional employees for the facility;

        .     integrating the facility's operations with our existing
              operations; and

        .     generating and increasing German facility sales and achieving
              profitability.

        Although the German facility has begun manufacturing our products and
making installations for customers in Europe, it has a very limited operating
history upon which to assess whether it will be able to meet all of the
challenges required to successfully operate and generate and increase sales. If
we are not able to generate and increase sales and profits at the German
facility, we will not receive the anticipated benefits of our investment in the
German facility and our business, financial condition and results of operations
would be materially and adversely affected.

                                       21



We Are Exposed to Risks Associated with the Recent Worldwide Economic Slowdown
and Related Uncertainties.

        Concerns about decreased consumer and investor confidence, reduced
corporate profits and capital spending, and recent international conflicts and
terrorist and military activity have resulted in a downturn in the equity
markets and a slowdown in economic conditions, both domestically and
internationally, and have caused concern about the strength or longevity of an
economic recovery. These unfavorable conditions could ultimately cause a
slowdown in customer orders or cause customer order cancellations. In addition,
recent political and social turmoil related to international conflicts and
terrorist acts may put further pressure on economic conditions in the U.S. and
worldwide. Unstable political, social and economic conditions make it difficult
for our customers, our suppliers and us to accurately forecast and plan future
business activities. If such conditions continue or worsen, our business,
financial condition and results of operations could be materially and adversely
affected.

If We Are Unable to Protect Our Intellectual Property Rights, Our Competitive
Position Could Be Harmed or We Could Be Required to Incur Expenses to Enforce
Our Rights.

        We anticipate that our future success will depend, in part, on our
ability to obtain and maintain patent protection for our products and
technology, to preserve our trade secrets and to operate without infringing the
intellectual property of others. We rely on patents to establish and maintain
proprietary rights in our technology and products. While we hold a number of
issued patents and have other patent applications pending on our products and
technology, we cannot assure you that any additional patents will be issued,
that the scope of any patent protection will exclude competitors or that any of
our patents will be held valid if subsequently challenged. In addition, other
companies may independently develop similar products, duplicate our products or
design products that circumvent our patents.

        Competitors may claim that we have infringed their current or future
intellectual property rights. We may not prevail in any future intellectual
property infringement litigation given the complex technical issues and inherent
uncertainties in litigation. Any claims, with or without merit, could be
time-consuming and distracting to management, result in costly litigation, cause
product shipment delays, or require us to enter into royalty or licensing
agreements. Additionally, in the event an intellectual property claim against us
is successful, we might not be able to obtain a license on acceptable terms or
license a substitute technology or redesign our products to avoid infringement.
Any of the foregoing adverse events could seriously harm our business, financial
condition and results of operations.

Product Liability Claims Against Us Could Be Costly and Could Harm Our
Reputation.

        The sale of dental and medical products involves the inherent risk of
product liability claims against us. While we currently maintain product
liability insurance coverage in an amount that we believe is adequate for our
level of sales, this insurance is expensive, is subject to various coverage
exclusions and may not be obtainable in the future on terms acceptable to us, or
at all. We do not know whether claims against us, if any, with respect to our
products would be successfully defended or whether our insurance would be
sufficient to cover liabilities resulting from such claims.

Rapid Changes in Technology Could Harm the Demand for Our Products or Result in
Significant Additional Costs.

        The markets in which our laser products compete are subject to rapid
technological change, evolving industry standards, changes in the regulatory
environment, frequent new device and pharmaceutical introductions and evolving
dental and surgical techniques. These changes could render our products
noncompetitive or obsolete. The success of our existing and future products is
dependent on the differentiation of our products from those of our competitors,
the timely introduction of new products and the perceived benefit to the
customer in terms of patient service and return on investment. The process of
developing new medical devices is inherently complex and requires regulatory
approvals or clearances that can be expensive, time-consuming and uncertain. We
have in the past experienced delays in product development. We cannot assure you
that we will successfully identify new product opportunities, be financially or
otherwise capable of the research and development to bring new products to
market in a timely manner or that product and technologies developed by others
will not render our products obsolete.

                                       22



We May Not Be Able to Compete Successfully Against Our Current and Future
Competitors.

        We compete with a number of foreign and domestic companies, including
companies that market traditional dental products such as dental drills, as well
as other companies that market laser technologies in the dental and medical
markets that we address. Some of our competitors have greater financial,
technical, marketing or other resources than us, which may allow them to respond
more quickly to new or emerging technologies and to devote greater resources to
the acquisition or development and introduction of enhanced products than we
can. In addition, the rapid technological changes occurring in the healthcare
industry are expected to lead to the entry of new competitors, especially as
dental and medical lasers gain increasing market acceptance. Our ability to
anticipate technological changes and to introduce enhanced products on a timely
basis will be a significant factor in our ability to grow and remain
competitive. New competitors or technology changes in laser products and methods
could cause commoditization of such products, require price discounting or
otherwise adversely affect our gross margins.

Changes in Government Regulation or the Inability to Obtain Necessary Government
Approvals Could Harm Our Business.

        Our products are subject to extensive government regulation, both in the
United States and other countries. To clinically test, manufacture and market
products for human diagnostic and therapeutic use, we must comply with
regulations and safety standards set by the U.S. Food and Drug Administration
and comparable state and foreign agencies. Generally, products must meet
regulatory standards as safe and effective for their intended use prior to being
marketed for human applications. The clearance process is expensive,
time-consuming and uncertain. The failure to receive requisite approvals for the
use of our products or processes, or significant delays in obtaining such
approvals, could prevent us from developing, manufacturing and marketing
products and services necessary for us to remain competitive.

If Our Customers Cannot Obtain Third Party Reimbursement for Their Use of Our
Products, They May Be Less Inclined to Purchase Our Products.

        Our products are generally purchased by dental or medical professionals
who may bill various third party payors, such as government programs or private
insurance plans, for all or a portion of the procedures conducted using these
products. In the United States, third party payors review and frequently
challenge the prices charged for medical services. In many foreign countries,
the prices are predetermined through government regulation. Payors may deny
coverage and reimbursement if they determine that the procedure was not
medically necessary (for example, cosmetic) or that the device used in the
procedure was investigational. We believe that most of the procedures being
performed with our current products generally have been reimbursed, with the
exception of cosmetic applications such as tooth whitening. For the portion of
dentists who rely on third party reimbursement and take assignment of patient
insurance claims, the inability to obtain reimbursement for services using our
products could deter them from purchasing or using our products. We cannot
predict the effect of future healthcare reforms or changes in financing for
health and dental plans. Any such changes could have an adverse effect on the
ability of a dental or medical professional to generate a return on investment
using our current or future products. Such changes would act as disincentives
for capital investments by dental and medical professionals and could have an
adverse effect on our business, financial condition and results of operations.

The Failure to Attract and Retain Key Personnel Could Adversely Affect Our
Business.

        Our future success depends in part on the continued service of certain
key personnel, including Jeffrey Jones, our Chief Executive Officer, Edson Rood,
our Chief Financial Officer, Ioana Rizoiu, our Vice President of Clinical
Research, and Keith Bateman, our Vice President of Global Sales. We do not have
employment agreements with any of our key employees, other than with Mr. Jones,
whose employment agreement was renewed in January 2002 for a two-year term.

        Our success will also depend in large part on our ability to continue to
attract, retain and motivate qualified engineering and other highly skilled
technical personnel. Competition for certain employees, particularly development
engineers, is intense despite the effects of the economic slowdown. We may not
be able to continue to attract and retain sufficient numbers of such highly
skilled employees. Our inability to attract and retain additional key employees
or the loss of one or more of our current key employees could adversely affect
our business, financial condition and results of operations.

                                       23



Potential Future Acquisitions Could Have Unintended Negative Consequences Which
Could Harm Our Business and Cause Our Stock Price to Decline.

        We may consider pursuing additional acquisitions of businesses, products
or technologies in the future as a part of our growth strategy. Acquisitions
could require significant capital infusions and could involve many risks,
including but not limited to the following:

        .     we may encounter difficulties in assimilating and integrating the
              operations, products and workforce of the acquired companies;

        .     acquisitions may materially and adversely affect our results of
              operations because they may require large one-time charges or
              could result in increased debt or contingent liabilities, adverse
              tax consequences, substantial depreciation or deferred
              compensation charges, or the amortization of amounts related to
              deferred compensation, goodwill and other intangible assets;

        .     acquisitions may be dilutive to our existing stockholders;

        .     acquisitions may disrupt our ongoing business and distract our
              management; and

        .     key personnel of the acquired company may decide not to work for
              us.

        We cannot assure you that we will be able to identify or consummate any
future acquisitions on acceptable terms, or at all. In the event we do pursue
any acquisitions, it is possible that we may not realize the anticipated
benefits from such acquisitions.

We May Not Be Able to Sustain or Increase Our Net Income in the Future, Which
May Cause the Trading Price of Our Common Stock to Decline.

        Although we expect to be able to sustain net income, there is no
assurance that we will be able to do so. Even if we sustain net income, we may
not be able to increase net income on a quarterly or annual basis in the future.
Our ability to sustain or increase net income is dependent on many of the risk
factors identified in this report. Until the third quarter of 2001, we had a
prior history of losses through our research and development phase and during
the early commercialization of our products. It is possible that we may
experience losses again in the future. If we are unable to sustain or increase
our net income in the future, we may not be able to successfully operate our
business and our stock price may decline.

Our Common Stock Price Has Been Volatile, Which Could Result in Substantial
Losses for Individual Stockholders.

        Our common stock is currently traded on the Nasdaq National Market and
the Nasdaq Europe Market and has only limited daily trading volume. The trading
price of our common stock has been and may continue to be volatile. The market
for technology companies, in particular, has, from time to time, experienced
extreme volatility that often has been unrelated to the operating performance of
particular companies. These broad market and industry fluctuations may
significantly affect the trading price of our common stock, regardless of our
actual operating performance. For example, the closing per share sale price of
our common stock has fluctuated between $6.58 and $3.80 over the course of 2002
despite steady improvement in our financial performance. On August 9, 2001, the
closing sale price of our common stock declined 12% from $5.87 per share on
volume of approximately 900,000 shares, absent any news about or announcements
by us. The trading price of our common stock could be affected by a number of
factors, including, but not limited to, changes in expectations of our future
performance, changes in estimates by securities analysts (or failure to meet
such estimates), quarterly fluctuations in our sales and financial results and a
variety of risk factors, including the ones described elsewhere in this report.
Periods of volatility in the market price of a company's securities sometimes
result in securities class action litigation. If this were to happen to us, such
litigation would be expensive and would divert management's attention. In
addition, if we needed to raise equity funds under adverse conditions it would
be difficult to sell a significant amount of our stock without causing a
significant decline in the trading price of our stock. If our stock price drops
below $3.00 per share for an extended period of time or we are otherwise unable
to satisfy the continued listing requirements of the Nasdaq National Market, our
shares could be delisted from the Nasdaq National Market and the marketability,
liquidity and price of our common stock would be adversely affected.

                                       24



Future Sales of Our Common Stock Could Affect the Stock Price.

        If our stockholders sell substantial amounts of our common stock,
including shares issued on the exercise of options and warrants, in the public
market, the market price of our common stock could fall. These sales also might
make it more difficult for us to sell equity or equity-related securities in the
future at a time and price that we deem appropriate.

We Have Adopted Anti-Takeover Defenses That Could Delay or Prevent an
Acquisition of Our Company and May Affect the Price of Our Common Stock.

        Certain provisions of our certificate of incorporation and stockholder
rights plan could make it difficult for a third party to acquire us, even though
an acquisition might be beneficial to our stockholders. These provisions could
limit the price that investors might be willing to pay in the future for shares
of our common stock.

        Our certificate of incorporation authorizes the issuance of up to
1,000,000 shares of "blank check" preferred stock, which will have terms as may
be determined from time to time by our Board of Directors. Accordingly, our
Board of Directors may, without obtaining stockholder approval, issue preferred
stock with terms, which could have preference over and adversely affect the
rights of the holders of common stock. This issuance may make it more difficult
for a third party to acquire a majority of our outstanding voting stock. We are
also subject to the Delaware anti-takeover laws, which may prevent, delay or
impede a merger or takeover of our company, and we have not opted out of the
provisions of such laws through either our certificate of incorporation or our
bylaws.

        In December 1998, we adopted a stockholder rights plan pursuant to which
one preferred stock purchase right is distributed to our stockholders for each
share of our common stock held by them. In the event that a third party acquires
15% or more of our outstanding common stock, the holders of these rights will be
able to purchase the underlying junior participating preferred stock as a way to
discourage, delay or prevent a change in control of our company. The mere
existence of a stockholder rights plan often delays or makes a merger, tender
offer or proxy contest more difficult. The existence of these features could
prevent others from seeking to acquire shares of our common stock in
transactions at premium prices.

                                       25



ITEM 4. CONTROLS AND PROCEDURES.

        (a) Evaluation of disclosure controls and procedures. We maintain
"disclosure controls and procedures," as such term is defined in Rule 13a-15(e)
under the Securities Exchange Act of 1934 (the "Exchange Act"), that are
designed to ensure that information required to be disclosed by us in reports
that we file or submit under the Exchange Act is recorded, processed,
summarized, and reported within the time periods specified in Securities and
Exchange Commission rules and forms, and that such information is accumulated
and communicated to our management, including our Chief Executive Officer and
Chief Financial Officer, as appropriate, to allow timely decisions regarding
required disclosure. In designing and evaluating our disclosure controls and
procedures, management recognized that disclosure controls and procedures, no
matter how well conceived and operated, can provide only reasonable, not
absolute, assurance that the objectives of the disclosure controls and
procedures are met. Additionally, in designing disclosure controls and
procedures, our management necessarily was required to apply its judgment in
evaluating the cost-benefit relationship of possible disclosure controls and
procedures. The design of any disclosure controls and procedures also is based
in part on certain assumptions about the likelihood of future events, and there
can be no assurance that any design will succeed in achieving its stated goals
under all potential future conditions.

     Based on their evaluation as of a date within 90 days of the initial filing
date of the Quarterly Report on Form 10-Q for the quarterly period ended
September 30, 2002, our Chief Executive Officer and Chief Financial Officer have
concluded that, subject to the limitations noted above and except as indicated
in paragraph (b) of this item, our disclosure controls and procedures were
effective to ensure that material information relating to us, including our
consolidated subsidiaries, is made known to them by others within those
entities, particularly during the period in which this Quarterly Report on Form
10-Q/A was being prepared.

        (b) Changes in internal control over financial reporting. There was no
change in our internal control over financial reporting (as defined in Rule
13a-15(f) under the Exchange Act) identified in connection with the evaluation
described in Item 4(a) above that occurred during our last fiscal quarter that
has materially affected, or is reasonably likely to materially affect, our
internal control over financial reporting. However, in September 2003, we were
notified by our independent accountants that there exists a material weakness
with respect to our internal controls surrounding our evaluation of the terms
and conditions of our arrangements with our customers to determine the
appropriate timing of revenue recognition. We have since modified and
standardized our purchase order forms to conform to the revenue recognition
criteria in SAB 101 and we are implementing controls over future modifications
to our purchase order forms.
