consolidated balance sheet as of October 2, 2005 and the related condensed
consolidated statements of operations and the condensed consolidated statements
of stockholders' equity and comprehensive income for the three and nine months
ended October 2, 2005 and October 3, 2004 are unaudited. The condensed
consolidated statements of cash flows for the nine months ended October 2, 2005
and October 3, 2004 are unaudited. In the opinion of management, all adjustments
necessary for the fair presentation of such financial statements have been
included. Such adjustments consisted only of normal recurring items. Interim
results are not necessarily indicative of results for the full year. These

On June 30, 2005, the Company executed a loan modification agreement on its
secured revolving loan agreement that allows for aggregate borrowings, including
letters of credit, up to a maximum of $13 million against a borrowing base of
secured accounts receivable. The Company may elect to borrow at interest rates
of either the bank's prime rate or LIBOR plus 2.25%. This loan agreement extends
to May 31, 2007 and is subject to maintaining certain financial covenants. At
October 2, 2005 borrowings outstanding under this agreement were $3.6 million
with the borrowing base formula permitting aggregate borrowings of approximately
$11.4 million.

(4)  Earnings Per Share (EPS)

Basic EPS is computed by dividing income available to common stockholders by the
weighted-average number of common shares outstanding during the period. Diluted
EPS is computed using the weighted average number of common and dilutive
potential common shares outstanding during the period, using the treasury stock
method. Options outstanding, which were not included in the determination of
diluted EPS for the three and nine months ended October 3, 2004 because they
were anti-dilutive due to the Company reporting a loss, were 1,148,939. In
addition, for the three and nine months ended October 2, 2005, 144,484 and
176,989 shares respectively, of common stock issuable relative to stock options
had exercise prices per share that exceeded the average market price of the
Company's common stock and were excluded from the calculation of the diluted
shares since their inclusion would be anti-dilutive.

The Company applies Accounting Principles Board Opinion No. 25 and related
Interpretations in accounting for its stock option and purchase plans.
Accordingly, no compensation cost has been recognized related to the plans. Had
compensation cost for the plans been determined based on the fair value at the
grant dates for the awards under these plans consistent with SFAS No. 123,
"Accounting for Stock-Based Compensation," the Company's net income (loss) and
net income (loss) per share would be the pro forma amounts indicated below (in
thousands, except per share data):

(6) Revenue Recognition

The Company recognizes revenue in accordance with the Securities and Exchange
Commission (SEC) Staff Accounting Bulletin (SAB) No. 101, "Revenue Recognition
in Financial Statements" as updated by SEC Staff Accounting Bulletin No. 104,
"Revenue Recognition". Under these guidelines, revenue is recognized when
persuasive evidence of an arrangement exists, shipment has occurred or services
rendered, the price is fixed or determinable and payment is reasonably assured.
Under these requirements, when the terms of sale include customer acceptance
provisions, and compliance with those provisions has not been previously
demonstrated, revenues are recognized upon acceptance. Furthermore, revenues for
products that require

installation for which the installation is essential to functionality or is not
deemed inconsequential or perfunctory are recognized upon completion of
installation. Revenues for products sold where installation is not essential to
functionality and is deemed inconsequential or perfunctory are recognized upon
shipment with estimated installation and warranty costs accrued.

Applying the requirements of SAB No. 101 to future sales arrangements used in
the Company's equipment sales may result in the deferral of the revenue for some
equipment sales.

The Company also has certain sales transactions for projects that are not
completed within the normal operating cycle of the business. These contracts are
accounted for on a percentage completion basis. Under the percentage completion
method, revenues are recognized based upon the ratio of costs incurred to the
total estimated costs. Revisions in costs and profit estimates are reflected in
the period in which the facts causing the revision become known. Provisions for
total estimated losses on uncompleted contracts, if any, are made in the period
in which such losses are determined.

For the three and nine months ended October 2, 2005, there was $1,639,256 and
$2,338,046, respectively of revenue recognized using the percentage of
completion method. For the nine months ended October 3, 2004, there was
$1,570,165 of revenue recognized using the percentage of completion method.

At October 2, 2005, there are no post shipment obligations that could impact
revenue recognition.

The Company accounts for shipping and handling costs billed to customers in
accordance with the Emerging Issues Task Force (EITF) Issue 00-10 "Accounting
for Shipping and Handling Fees and Cost". Amounts billed to customers for
shipping and handling costs are recorded as revenues with the associated costs
reported as cost of goods sold.

(7) Product Warranty Costs

The Company provides standard warranty coverage for parts and labor for 12
months and special extended material only coverage on certain other products.
The Company sets aside a reserve for anticipated warranty claims based on
revenue. The reserve for warranty covers the estimated costs of material, labor
and travel. Actual warranty claims incurred are charged to expense. Factors that
affect the Company's product warranty liability include the number of installed
units, the anticipated cost of warranty repairs and historical and anticipated
rates of warranty claims.

The following table reflects changes in the Company's accrued warranty account
during the nine months ended October 2, 2005 (in thousands):

(8) Recent Accounting Pronouncements

In December 2004, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No.123 (revised
2004),"Share-Based Payment". Statement 123(R) will provide investors and other
users of financial statements with more complete and neutral financial
information by requiring that the compensation cost relating to share-based
payment transactions be recognized in financial statements. That cost will be
measured based on the fair value of the equity or liability instruments issued.
Statement 123(R) covers a wide range of share-based compensation arrangements
including share options, restricted share plans, performance-based awards, share
appreciation rights, and employee share purchase plans. Statement 123(R)
replaces FASB Statement No. 123, Accounting for Stock-Based Compensation, and
supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees.
Statement 123, as originally issued in 1995, established as preferable a
fair-value-based method of accounting for share-based payment transactions with
employees. However, that Statement permitted entities the option of continuing
to apply the guidance in Opinion 25, as long as the footnotes to financial
statements disclosed what net income would have been had the preferable
fair-value-based method been used. The Company will be required to apply
Statement 123(R) in our financial statements in the first quarter of fiscal
2006. The Company is currently evaluating the financial statement impact of the
adoption of Statement 123(R).

In November 2004, the FASB issued SFAS No. 151 "Inventory Costs", an amendment
of ARB No. 43, Chapter 4. The amendments made by Statement 151 clarify that
abnormal amounts of idle facility expense, freight, handling costs, and wasted
materials (spoilage) should be recognized as current-period charges and require
the allocation of fixed production overheads to inventory based on the normal
capacity of the production facilities. The guidance is effective for inventory
costs incurred during fiscal years beginning after June 15, 2005. Earlier
application is permitted for inventory costs incurred during fiscal years
beginning after November 23, 2004. The Company is currently evaluating the
financial statement impact of the adoption of Statement 151.

Net Sales. The growth in total revenues in the third quarter was primarily due
to an increase in sales of our energy generation products. Year to date growth
in revenue has primarily been from the energy generation and surface mount
technology (SMT) products.

</TABLE>

The third quarter of 2005 showed a continued trend of a greater percentage of
sales in Asia Pacific. We expect a continuing revenue shift from the United
States to Asia which is indicative of our multinational customers transferring
their manufacturing operations from domestic facilities to Asian operations to
attain lower costs and be closer to their markets. The Company has established
furnace assembly operations in China to remain competitive in response to this
trend.

Gross Profit. The increase in the gross profit percentage for the third quarter
and the first nine months of 2005 was principally the result of lower costs in
our U.S. operations and due to improvements and expansion in our China assembly
and China material sourcing operations, combined with a favorable product mix.

Selling, General and Administrative. The increase in selling, general and
administrative expense in absolute dollars and as a percentage of net sales in
2005 was due to increased commission costs resulting from additional sales and
higher commission rates as discounts on products decreased. Also, the Company
increased its spending for customer service, sales, marketing and administration
related costs in line with its expanding business needs.

Research, Development and Engineering. In the third quarter of 2005, the Company
has increased its spending on RD&E versus the first half of 2005, although the
total spending is below 2004 levels.

Operating Income. The increase in operating income was primarily the result of
increased revenues and improved margins.

Income Taxes. The Company has federal and state net operating loss carry
forwards of approximately $12 million. Accordingly, no income tax provision is
reflected in the Statement of Operations for the three and nine months ended
October 2, 2005. The Company has recorded a full valuation allowance to offset
the deferred tax asset arising as a result of these loss carryforward because of
uncertainty surrounding realization. Our statutory federal income tax rate is
34.0%.

LIQUIDITY AND CAPITAL RESOURCES

As of October 2, 2005, the Company had $0.6 million in cash and cash
equivalents.

During the nine months ended October 2, 2005, the Company used net cash
resources of approximately $1.5 million for operating activities. This use of
cash was primarily the result of an increase in accounts receivable of $6.6
million, and an increase in inventory of $0.6 million; offset by an increase in
accounts payable of $0.7 million, adding back depreciation and amortization of
$0.7 million, an increase in current liabilities of $1.3 million, a decrease in
other assets of $0.5 million and a net profit of $2.5 million.

The Company's accounts receivable increased by $6.6 million or 72% in the nine
months ended October 2, 2005. The Company has increased its accounts receivable
reserves by a similar percentage.


                                       12

On June 30, 2005, the Company executed a loan modification agreement on its
secured revolving loan agreement that allows for aggregate borrowings, including
letters of credit, up to a maximum of $13 million against a borrowing base of
secured accounts receivable. The Company may elect to borrow at interest rates
of either the bank's prime rate or LIBOR plus 2.25%. This loan agreement extends
to May 31, 2007 and is subject to maintaining certain financial covenants. At
October 2, 2005 borrowings outstanding under this agreement were $3.6 million
with the borrowing base formula permitting aggregate borrowings of approximately
$11.4 million.

We have a mortgage note that is secured by our real property in Billerica, MA.
The mortgage note had an outstanding balance at October 2, 2005 of approximately
$5.3 million. The mortgage requires monthly payments of $38,269, which includes
interest calculated at the rate of 5.42% per annum. This mortgage note payable
has a balloon payment of $5.1 million due and payable at maturity on December
26, 2006, if the Company does not exercise its option to a three-year
contractual extension.

There are no material commitments for capital expenditures as of October 2,
2005.

The Company's business forecasts project that our cash position, cash flow and
our working capital line of credit will be sufficient to meet our corporate,
operating and capital requirements through 2006.

OTHER MATTERS

The impact of inflation and the effect of foreign exchange rate changes during
2005 have had no material impact on our business and financial results.

RECENT ACCOUNTING DEVELOPMENTS

See 2004 Annual Report on Form 10-K, on file with the SEC.

FORWARD LOOKING STATEMENTS

This Report, other than historical financial information, includes
forward-looking statements that involve known and unknown risks and
uncertainties, including quarterly fluctuations in results. In particular, our
forecast of compliance with financial covenants in our bank agreement is a
forward-looking statement. Such statements are made pursuant to the "safe
harbor" provisions under the securities laws, and are based on the assumptions
and expectations of the Company's management at the time such statements are
made. Important factors that could cause actual results to differ include the
timely availability and acceptance of new products, general market conditions
governing supply and demand, the impact of competitive products and pricing and
other risks detailed in the Company's filings with the Securities and Exchange
Commission. Actual results may vary materially. Accordingly, you should not
place undue reliance on any forward-looking statements. Unless otherwise
required by law, the Company disclaims any obligation to revise or update such
forward-looking statements in order to reflect future events or developments.

FACTORS THAT MAY AFFECT FUTURE RESULTS

We are subject to cyclical downturns in the electronics and semiconductor
industry.

Our business depends predominantly on the capital expenditures of electronics
and semiconductor manufacturers, which in turn depend on current and anticipated
market demand for printed circuit board and integrated circuits and the products
that use them. The electronics and semiconductor industry has historically been
very cyclical and has experienced periodic downturns that have had a material
adverse effect on the demand for electronic and semiconductor processing
equipment, including equipment that we manufacture and market. During periods of
reduced and declining demand, we must be able to quickly and effectively align
our costs with prevailing market conditions, as well as motivate and retain key
employees. In particular, our inventory levels during periods of reduced demand
have at times been higher than optimal, relative to the current levels of
production demand. We cannot provide any assurance that we may not be required
to make inventory valuation adjustments in future periods. During periods of
rapid growth, we may fail to acquire and/or develop sufficient manufacturing
capacity to meet customer demand, and hire and assimilate a sufficient number of
qualified people. Our business may be adversely affected if we fail to respond
to rapidly changing industry cycles in a timely and effective manner.


                                       13

<PAGE>

We have shifted a portion of our production capacity to a new and expanding
manufacturing facility in Shanghai, China.

In 2004, the Company began manufacturing and material sourcing operations in a
new leased facility in Shanghai, China. The volume and variety of the Company's
products produced in China has continued to increase throughout 2005. The
successful operation of our China facility is important to sustaining our
business profitability and allowing us to remain competitive. We need to address
successfully the transitional leadership, management, technical and
administrative organization requirements of doing business in China. If we are
not successful in managing our China operations, our business and profitability
will be adversely affected. During 2005, the Company began the construction of
additional facilities, which will be leased, and we will need to execute this
expansion successfully to realize the benefit of our China operations in 2006
and beyond.

If we are unable to increase sales and reduce costs, our profitability may be
affected negatively.

During the first nine months of 2005, we generated net income of $2.5 million.
This compares to a loss of $4.3 million during the same period in 2004, which
included a restructuring charge of $1.6 million. Our increased net income was
mainly due to a combination of a 14.9% increase in net sales and an increase in
gross profit percentage from 23.0% to 35.6%, resulting in a 77.5% increase in
gross profit dollars. We attribute this increase in gross profit primarily to
reduced costs resulting from better procurement management in the U.S. and our
global sourcing of materials, as well as manufacturing efficiencies achieved
with the transition of a portion of production to China. We may not experience
comparable cost reductions in future periods.

In addition, our reported net income will be negatively impacted when we begin
to expense stock options pursuant to Statement of Financial Accounting Standards
(SFAS) No. 123 (revised 2004), "Share-Based Payment," which will increase our
reported operating expenses. We expect to recognize the effects of SFAS No.
123(R) in our financial statements beginning in the first quarter of 2006.

If we do not have access to additional credit, we may not be able to take
advantage of increased growth in the markets that we serve.

Historically, we have relied on access to credit to finance growth of our
business. Our bank imposes restrictions on our ability to borrow under our
credit agreement. Although we believe this line of credit provides us with
sufficient credit to finance our 2006 business plan, it may not be sufficient to
allow us to take full advantage of higher than anticipated increases in orders
for our products. In addition, if we do not continue to comply with our bank
covenants, we may not be able to borrow, and our business would be adversely
affected.

If we do not generate positive cash flow from operations, we will need to incur
more debt or issue additional stock.

Over the past several years we have consistently used more cash in our
operations that we have generated from them and, as a result, have relied on
external financing to fund our operations. We will need to generate positive
cash flow from our operating activities for our business to be successful. We
had $0.6 million in cash as of October 2, 2005. If we borrow additional funds,
our level of indebtedness will rise which may harm our financial condition and
results of operations by increasing our vulnerability to adverse changes in
general economic and industry conditions and limiting our ability to obtain
additional financing for capital expenditures, acquisitions and general
corporate and other purposes. If, to fund our operations, we issue additional
shares of stock, our shareholders may be diluted. Furthermore, we may not be
able to obtain additional equity or debt financing on acceptable terms or at
all.

Our future success will depend on our ability to effectively develop and market
our products against those of our competitors.

The industry in which we compete is extremely competitive. Some of our
competitors have substantially greater financial, engineering, manufacturing and
customer support capabilities and offer more extensive product offerings. If
customers prefer products offered by our competitors, we will have difficulty
maintaining or increasing our revenue. Our principal competitors for advanced
semiconductor packaging are Sikama, Semigear and Heller Industries. Our
principal competitors for solder reflow systems are Vitronics-Soltec, Inc. (a
Dover Technologies Company), Heller Industries, Futakawa, ERSA, Rehm, and
Electrovert-Speedline Technologies. Our systems for the Energy generation
markets and other applications compete primarily against SierraTherm Production
Furnaces, Inc., RTC, Centrotherm and Harper International Corp. We expect our
competitors to continue to improve the design and performance of their current
products and to introduce new products with improved performance capabilities.
Our failure to introduce new products in a timely manner, or the introduction by
our competitors of products with perceived or actual advantages, could result in
reduced sales of, or lower margins on, our products. In future years, we expect
to face increased competition based on price, particularly from companies in
Asia. If we are unable to reduce the costs of our products or introduce new
lower cost products, we will lose sales to these competitors.

Our international sales and operations are subject to the economic, political,
legal and business environments of the countries in which we do business, and
our failure to operate successfully or adapt to


                                       14

<PAGE>

changes in these environments could cause our international sales and operations
to be limited or disrupted.

Our international sales accounted for approximately 83.1% of our consolidated
revenue for the nine months ended October 2, 2005. We expect to continue to
generate a significant percentage of our revenue outside the United States for
the foreseeable future. In addition, we have direct investments in a number of
subsidiaries outside of the United States, primarily in Asia and Europe. Our
international operations could be limited or disrupted, and the value of our
direct investments may be diminished, by any of the following:

     -    fluctuations in currency exchange rates;

     -    the imposition of governmental controls;

     -    import and export license requirements;

     -    political instability;

     -    difficulties enforcing contractual and intellectual property rights;

     -    terrorist activities and armed conflict;

     -    restrictions on direct investments by foreign entities and trade
          restrictions;

     -    changes in tax laws and tariffs;

     -    costs and difficulties in staffing and managing international
          operations; and

     -    longer payment cycles.

In addition, the Foreign Corrupt Practices Act prohibits U.S. companies and
their representatives from offering, promising, authorizing or making payments
to foreign officials for the purpose of obtaining or retaining business abroad.
Failure to comply with domestic or foreign laws could result in various adverse
consequences, including the imposition of civil or criminal sanctions.

We conduct a portion of our business in currencies other than the U.S. dollar.
We recognize foreign currency gains or losses arising from our operations in the
period in which we incur those gains or losses. As a result, currency
fluctuations among the U.S. dollar and the currencies in which we do business
have caused foreign currency transaction gains and losses in the past and will
likely do so in the future. Because of the number of currencies involved, the
variability of currency exposures and the potential volatility of currency
exchange rates, we may suffer foreign currency transaction losses in the future
due to the effect of exchange rate fluctuations.

Because a majority of our revenue is generated from sales in Asia, our
operations are particularly vulnerable to instability in that region and
competition from Asian organizations.

During the nine months ended October 2, 2005, approximately 51.2% of our revenue
was generated from sales in the Asia Pacific region of the world. Political or
economic instability in any of the major Asian economies may adversely impact
the demand for capital equipment, including equipment of the type we manufacture
and market. In addition, we face competition from a number of Asian suppliers
that have certain advantages over U.S. suppliers, including us. These advantages
include, among other things, proximity to customers, favorable tariffs and
affiliation with significantly larger organizations. In addition, changes in the
amount or price of electronics produced in Asia could negatively impact spending
by our customers.

The occurrence of natural disasters in Asia may adversely impact our operations
and sales.

We have an expanding engineering and manufacturing facility in China, and the
majority of our sales are made to destinations in Asia. Asia is known for being
vulnerable to natural disasters and other risks, such as earthquakes, floods and
avian (bird) flu, which at times have disrupted the local economies. A
significant earthquake or health crisis could materially affect operating
results. We are not insured for most losses and business interruptions of this
kind, and we do not have redundant, multiple site capacity in the event of a
natural disaster. In the event of such disaster, our business would suffer.

Failure of critical suppliers to deliver sufficient quantities of parts in a
timely and cost-effective manner would adversely impact our operations.

We use numerous vendors to supply components for the manufacture of our
products. We do not have multiple qualified suppliers for all of the parts we
use. Some key parts may only be available from a single supplier. Accordingly,
we may experience problems in obtaining adequate and reliable quantities of
various components. In addition, suppliers may cease manufacturing certain
components that are difficult to


                                       15

<PAGE>

replace without significant reengineering of our products. Our results of
operations will be materially adversely impacted if we are unable to obtain
adequate supplies of components in a timely and cost effective manner.

If we fail to maintain positive relationships with particular individuals, we
may be unable to successfully grow our business.

Our future operating results depend substantially upon the continued service of
our key personnel, some of whom are not bound by employment or non-competition
agreements. Our future operating results also depend in significant part upon
our ability to attract and retain qualified management, manufacturing,
technical, engineering, marketing, sales and support personnel. Competition for
qualified personnel, particularly those with technical skills, is intense, and
we may fail to attract and retain qualified personnel. Our business, financial
condition and results of operations could be materially adversely affected by
the loss of any of our key employees, by the failure of any key employee to
perform in his or her current position, or by our inability to attract and
retain skilled employees.

Because the emerging fuel cell technology for the energy generating market has
not been commercially proven yet, and we have limited experience in servicing
this customer base, we may not be able to successfully grow this business.

The developing fuel cell sector of the energy markets is in a stage of product
development without any guarantees of commercial success. There is therefore
considerable risk that this technology may not succeed and our business may not
develop. We have only recently expanded our product offerings to the fuel cell
sector of the energy market. Historically, we have focused on other sectors of
the energy markets. Given our limited experience in this segment of the energy
generation market, we may encounter problems growing this part of our business.

The market for nuclear fuel pellets used in power generation is dependent upon
the further growth in nuclear power production. Consequently, without growth in
the production of nuclear power, our opportunities to grow in this area will be
limited. In addition, we rely upon export licenses to supply this type of
equipment to several countries in the world. Failure to maintain such licenses
and obtain new licenses will limit our ability to expand our revenue from this
market.

The solar energy sector is dependent upon continuation of governmental
subsidies. A decline in these subsidies would reduce our ability to grow this
aspect of our business. The solar energy sector also depends on the availability
of raw materials such as silicon. Limits in the supply of these raw materials
will constrain growth in this sector and, therefore, limit our prospects for
increasing sales in this area.

Because our primary computer business system is outdated, a significant
malfunction could disrupt the activities of the Company.

Our manufacturing business system is at the end of its life, potentially posing
a risk to the operation of our business. Some of the computer system hardware
and software have limited support, which could result in an interruption in
business activities. Solutions to address these risks include: a disaster
recovery plan; hardware and software replacement; and a new enterprise business
system being developed, but may not be developed in time. Even if this system
does not malfunction, it will not be sufficient to continue to support our
operations.

Some of the requirements of Sarbanes-Oxley affect us as a small company
disproportionately, and we may not be able to comply despite substantial effort
and expense.

The Sarbanes-Oxley Act of 2002 imposed many new requirements on public
companies, the most significant of which involves the documentation, testing and
reporting of the effectiveness of our internal control over financial reporting.
Although we are not required to be in compliance until our annual report for the
year ended December 2006, we have already begun documenting and testing our
internal controls in a way that we have never before been required to do. We
expect this effort will involve substantial time and expense, and we cannot be
sure that we will be able to complete the task or that our internal controls
will meet the standards that are currently required. In connection with our
efforts to date, we have reviewed various significant control deficiencies that
have been identified by our registered public accounting firm. The issues
involved, among other things, include a computer accounting system that does not
meet our current and future needs, the lack of a well defined and documented
disaster recovery system and the need to improve and update the documentation of
our policies, procedures, and related internal controls surrounding our
accounting and financial reporting functions. Although we are not yet required
to report on our assessment of the effectiveness of our internal control over
financial reporting, and provide the required auditor attestation, until at
least the end of the next fiscal year, there is more than a remote likelihood
that our registered public accounting firm could inform us of one or more
material weaknesses before we complete our compliance and remediation efforts.
We are working to address the issues raised by these control deficiencies, but
we may not be successful in remediating them within the required time frame.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We do not believe that we have any material market risk exposure with respect to
derivative or other financial instruments.


                                       16

Item 4. CONTROLS AND PROCEDURES

Our management, including our Chief Executive Officer and Chief Financial
Officer, conducted an evaluation as of the end of the period covered by this
Report, of the effectiveness of our disclosure controls and procedures. Based on
that evaluation, our Chief Executive Officer and Chief Financial Officer
concluded that our disclosure controls and procedures were effective as of the
end of the period covered by this Report.

There were no changes to our internal control over financial reporting during
the quarter covered by this report that have materially affected, or are
reasonably likely to materially affect, our internal control over financial
reporting. However, the Company has begun the process of preparing for the
eventual reporting of the effectiveness of its internal controls over financial
reporting required by the Sarbanes-Oxley Act. In connection therewith,
management has reviewed various significant control deficiencies that have been
identified by its registered public accounting firm. The issues involved, among
other things, include a computer accounting system that does not meet the
Company's current and future needs, the lack of a well defined and documented
disaster recovery system and the need to improve and update the Company's
documentation of the policies, procedures and related internal controls
surrounding the accounting and financial reporting functions of the Company.
Although the Company is not required to report on its assessment of the
effectiveness of its internal control over financial reporting, and provide the
required auditor attestation, until at least the end of the next fiscal year,
there is more than a remote likelihood that its registered public accounting
firm could inform the Company of one or more material weaknesses before the
Company has completed its compliance and remediation efforts. The Company is
working to address the issues raised by these control deficiencies, but it may
not be successful in remediating them within the required timeframe.
