                                   THE COMPANY

We develop and commercialize minimally invasive medical procedures that employ
our laser technologies and associated disposable products. Using our proprietary
technology, including our exclusive rights to U.S. Patent No. 6,398,777, we
currently focus on endovenous laser treatment (EVLT(R)) of varicose veins. We
also develop and market lasers and disposable products for photodynamic therapy
(PDT) cancer procedures and products for other clinical applications, including
dental and general surgical procedures. We carry on our business primarily
through our wholly-owned subsidiaries, Diomed, Inc. and Diomed, Ltd.

In developing and marketing our clinical solutions, we use proprietary
technology and aim to secure strong commercial advantages over competitors by
obtaining exclusive commercial arrangements, gaining governmental approvals in
advance of others and developing and offering innovative practice enhancement
programs including physician training and promotional materials. To optimize
revenues, we focus on clinical procedures that generate revenues from both
capital equipment and disposable products, such as procedure kits and optical
fibers.

Our high power semiconductor diode lasers combine clinical efficacy, operational
efficiency and cost effectiveness in a versatile, compact, lightweight,
easy-to-use and easy-to-maintain system. Using our proprietary technology,
including our exclusive rights to U.S. Patent No. 6,398,777 and related foreign
patents for the endovenous laser treatment of varicose veins, we currently focus
on endovenous laser treatment (our EVLT(R) product line) for use in varicose
vein treatments, photodynamic therapy (our PDT product line) for use in cancer
treatments, and other clinical applications.

Our principal executive offices are located at One Dundee Park, Andover, MA
01810. Our telephone number is (978) 475-7771.

(1) Includes approximately 7.2 million shares held by affiliates. See "Security
Ownership of Certain Beneficial Owners and Management," below.

(2) This number (i) assumes (a) the full exchange of the 4 million shares of
preferred stock we issued in our private placement equity financing on September
30, 2005 for 4 million shares of common stock, (b) that a total of $5.9 million
in dividends will accrue on the preferred stock and that we pay all such
dividends in the form of common stock at an average price per share of $2.00,
(c) the full exercise of the common stock purchase warrants that we issued in
our private placement financing on September 30, 2005 for 1.6 million shares of
common stock, (d) the full exercise of the common stock purchase warrants for
200,000 shares of common stock that we issued on September 30, 2005 to the
holders of then-outstanding variable rate convertible debentures that we issued
in our private placement financing on October 25, 2004 as an inducement for the
waiver of negative covenants that would have precluded us from making certain
agreements in favor of the investors in the private placement financing that we
completed on September 30, 2005 and (ii) reflects a 25% allowance for possible
increase in common stock that may become issuable pursuant to antidilution
provisions of the preferred stock and warrants that we issued on September 30,
2005. See "Selling Stockholders - Determination of Number of Shares to be
Registered," below for details regarding how we calculated the number of shares
to be registered under this registration statement of which this prospectus is a
part.

conditions. You should carefully consider the following risk factors as well as
other information in this prospectus before purchasing our common stock. The
risks and uncertainties described below are intended to be the material risks
that are specific to us and to our industry. If any of the following risks
actually occur, the market price of our common stock could decline, and you may
lose all or a significant part of the money you paid to buy our common stock.
There may be other risks which we do not believe are currently material that may
nonetheless impair our business.

The following risks relate primarily to general business issues including, our
business plan, operations, revenues, losses, manufacturing, distribution, sales,
marketing, distribution and personnel:

WE HAVE A HISTORY OF SIGNIFICANT OPERATING LOSSES. WE MAY NOT EVER ACHIEVE OR
MAINTAIN PROFITABILITY.

We have incurred significant operating losses since our inception, and, as of
September 30, 2005, we have accumulated a deficit of approximately $78.3
million, including approximately $17.5 million in non-cash interest expense. We
may continue to incur operating losses, depending largely upon the commercial
success of our EVLT(R) product line. We will need to generate revenues in excess
of our expenses to become profitable, and we may be unable to do so. If we do
not become profitable, the value of our common stock may decline.

Our operating losses may increase as we continue to incur costs for research and
development, regulatory, sales and marketing, manufacturing and general
corporate activities. Whether we achieve and maintain profitability depends in
part upon our ability, alone or with others, to successfully complete the
development of future clinical applications, obtain required regulatory
clearances and sell our products at profitable prices.

YOU MAY HAVE DIFFICULTY EVALUATING AN INVESTMENT IN OUR STOCK BECAUSE WE HAVE A
LIMITED OPERATING HISTORY IN OUR CURRENT MARKETS.

Although we were founded in 1991, we have commercially offered the products used
in our EVLT(R) product line only since late 1999 in Europe and January 2002 in
the United States. As a result, you can evaluate our business only on this very
limited operating history. This short history may not provide an adequate basis
for you to fully assess our ability to successfully develop or achieve market
acceptance of our products, or to respond to competition.

OUR REQUIRED EXPENDITURES MAY EXCEED OUR BUDGETED EXPENSES, AND WE MAY NOT BE
ABLE TO PAY FOR UNANTICIPATED EXPENSES OUT OF REVENUE OR OBTAIN ADDITIONAL
INVESTMENT CAPITAL TO FUND THESE EXPENSES.

In November 2003, we completed a private placement equity financing transaction
in which we raised gross proceeds of $22 million and satisfied $1.2 million in
debt which we had incurred in a May 2003 bridge financing.

In April 2004, we completed a targeted offering to stockholders of records as of
August 29, 2003, in which we raised gross proceeds of approximately $3 million.

In October 2004, we completed a private placement equity and debt financing
transaction in which we raised gross proceeds of $10.6 million.

In September 2005, we completed a private placement equity financing transaction
in which we raised gross proceeds of $10 million.

We have applied, and will continue to apply these proceeds, net of offering
costs, together with our operating revenue, to pay for our general working
capital needs. However, the capital that we received from our recent equity and
debt financings may not be sufficient to pay for all of our required
expenditures if we have underestimated our expenditures or have overestimated
our revenues when we prepared our business plan. We may need additional
resources to fund the growth, acquisitions and working capital that our business
plan envisions. The timing and amount of our future capital requirements will
depend on many factors, including:


                                       6


      - the scope and results of preclinical studies and clinical trials;

      - the time and costs involved in obtaining regulatory approvals;

      - the costs involved in preparing, filing, prosecuting, maintaining and
        enforcing our patents;

      - the costs involved in litigation;

      - competing technological and market developments;

      - our ability to establish additional collaborations;

      - changes in existing collaborations;

      - our dependence on others for development of our potential products;

      - the cost of manufacturing, marketing and distribution;

      - the opportunities available for making acquisitions that would enhance
        our business; and

      - the effectiveness of our activities.


If we require additional funds, we cannot be certain that such funds will be
available to us on reasonable terms, or at all. In particular, given our capital
structure after completing the September 30, 2005 equity financing and the
current market price of our common stock, we may not be able to attract further
new investment capital in the near future. The inability to obtain additional
financing could cause us to reduce or cease operations, sell all or a portion of
our assets, seek a sale of our business or enter into a business combination
with a third party.

WE MAY NEED TO EXPAND OUR EXISTING MARKETING AND SALES RESOURCES.

Our marketing and sales resources may not be adequate for the successful
commercialization of our products. Currently, we rely primarily on direct sales
representatives for the U.S. market and independent distributors for the
international market. Direct sales representatives are our employees. Direct
sales representatives are paid a salary plus commissions on sales they make.
Distributors purchase products from us and then resell our products and services
to third parties. Our officers and employees develop and implement our marketing
strategy, although we do periodically engage non-employee consultants, acting as
independent contractors, to assist us in these efforts.

As of December 1, 2005, we employed 19 full time sales representatives, two
regional sales managers, a vice president of North American sales, as well as
four clinical specialists.

Market forces, such as increasing competition, increasing cost pressures on our
customers and general economic conditions, may require us to devote more
resources to our sales and marketing efforts, such as changing the composition
of our sales and marketing staff and changing our marketing methods, as well as
the expansion of our product lines. These changes may result in additional
expenses. For example, we will incur additional salary expenses if we increase
hiring of direct sales representatives to replace any distributors that we use.
Similarly, if we increase our reliance on marketing efforts, we will incur
greater costs.

As we expand our sales force and increase our marketing activities, we cannot
make any assurances that those efforts will result in more sales or higher
revenue. Further, even if we increase our spending on sales and marketing, we
may not be able to maintain our current level of sales.

WE MAY NEED TO EXPAND OUR EXISTING MANUFACTURING AND DISTRIBUTION CAPABILITIES.

Our manufacturing and distribution capabilities, and any current or future
arrangements with third parties for these activities, may not be adequate for
the successful commercialization of our products.

To be successful, we must manufacture our products in commercial quantities, at
acceptable costs and under standards imposed by the FDA and other regulators. We
currently have the capacity to manufacture products at certain commercial levels
within existing good manufacturing practices. Future regulatory clearances by
the FDA and other regulatory agencies could result in the need to expand our
manufacturing operations. If we expand our manufacturing capabilities, we may
need to spend substantial funds, hire and retain significant additional
personnel and comply with extensive regulations. If we are not able to expand
our manufacturing capabilities, or are unable to continue to comply with good
manufacturing practices, our ability to grow and to maintain our competitiveness
may be significantly hindered.

WE RELY ON OUR AGREEMENTS WITH OUR SUPPLIERS. IF WE FAIL TO MAINTAIN OR
ESTABLISH THESE AGREEMENTS, WE MAY NOT BE ABLE TO OBTAIN MATERIALS THAT ARE
NECESSARY TO DEVELOP OUR PRODUCTS AND THEIR APPLICATIONS.

                                       7


We depend on outside suppliers for certain raw materials and other components
for our products, including the diodes for our lasers. Raw materials or
components that we need may not always be available at our standards or on
acceptable terms, if at all, and we may be unable to get alternative suppliers
or produce needed materials or components on our own. If we cannot obtain these
raw materials or components, we may be unable to make our products in sufficient
quantities to meet our customers' needs. Moreover, lead times for components and
materials may vary significantly depending on the size of the order, specific
supplier requirements and current market demand for the components. Inability of
our suppliers to meet our requirements on a timely basis could interrupt our
production until we obtain an alternative source of supply. To date, we have not
experienced significant delays in obtaining any of our products.

We may also be unable to develop new products and applications and conduct
clinical trials. This will, in turn, hinder our ability to obtain regulatory
approval of these applications, thereby impairing our ability to expand our
markets or create products for new treatments.

In August 2005, we entered into an agreement with Luminetx Corporation
("Luminetx") whereby Luminetx appointed us as its exclusive distributor of its
new VeinViewer(TM) product to physicians performing sclerotherapy, phlebectomies
or varicose vein treatments, in North American and the United Kingdom. Luminetx
has received FDA clearance for VeinViewer(TM) in 2004, but has not yet
manufactured commercial quantities of this product. Luminetx expects to do so in
the first quarter of 2006. If Luminetx is unable to achieve its manufacturing
capacity, we will not be able to fulfill our expectations with respect to
VeinViewer(TM) revenue.

WE MAY NOT BE ABLE TO ATTRACT AND RETAIN KEY PERSONNEL AND CONSULTANTS. IF WE
FAIL TO DO SO, WE MAY NOT BE ABLE TO DEVELOP OUR APPLICATIONS.

Our success depends in large part on our ability to attract and retain highly
qualified management and other personnel. We depend upon the principal members
of our management team, key employees, staff and consultants that we engage from
time to time. Competition for this talent is intense, and we may not be able to
continue to attract and retain this talent. If we are unable to attract and
retain skilled personnel, our business would suffer.

We have limited resources to attract and retain personnel. Our ability to
compensate and provide incentives to management and our employees depends on our
financial resources and the availability of equity compensation. In the fourth
quarter of 2003, our stockholders approved a new incentive compensation plan
providing for up to 1.6 million shares of common stock to be issued to our
officers, directors, employees and consultants. On May 17, 2005, at our annual
meeting of stockholders, the stockholders approved an amendment to that plan
increasing the number of shares available for grant to 3.1 million. As of
November 1, 2005, approximately 1.5 million shares were available for grant
under this incentive plan. This amount may not be adequate for our needs, and we
may wish to adopt a new incentive plan or increase the number of shares
available under our existing plans. Any new incentive plan will require
stockholder approval before we may grant any stock options or other equity
compensation under a new plan.

In addition, our directors and senior officers are likely to require that we
maintain directors' and officers' insurance at levels comparable to that which
we have maintained in the past. The premiums for this coverage represent a
significant expense and are subject to substantial increases if the insurance
market becomes more limited. Our current directors' and officers' liability
insurance policies provide this coverage through February 2006. If we are unable
to provide adequate compensation or are unable to obtain sufficient directors'
and officers' insurance coverage, we may not be able to attract or retain key
personnel.

Personnel changes may disrupt our operations. Hiring and training new personnel
will entail costs and may divert our resources and attention from
revenue-generating efforts. From time to time, we also engage consultants to
assist us in our business and operations. These consultants serve as independent
contractors, and we therefore do not have as much control over their activities
as we do over the activities of our employees. Our consultants may be affiliated
with or employed by other parties, and some may have consulting or other
advisory arrangements with other entities that may conflict or compete with
their obligations to us. Inventions or processes discovered by these persons
will not necessarily become our property. If we are unable to find alternative
talent, we will not be in a position to avoid or negotiate terms that would seek
to protect us from these conditions.

WE MAY SUFFER LOSSES OR ENCOUNTER OTHER PROBLEMS AS A RESULT OF FUTURE BUSINESS
COMBINATIONS AND ALLIANCES.

We may expand our operations and market presence by entering into business
combinations, joint ventures, co-branding or other strategic alliances with
other companies. These transactions create risks, such as:

      - difficulty in assimilating the operations, technology and personnel of
the combined companies;

      - the disruption of our ongoing business, including loss of management
focus on existing businesses and other market developments;

      - problems retaining key technical and managerial personnel;

      - expenses associated with the amortization of intangible assets;

      - additional operating losses and expenses of acquired businesses;

      - impairment of relationships with existing employees, customers and
business partners; and

      - additional losses from any equity investments we might make or the
assumption of liabilities from third parties that we combine with.

We may not succeed in addressing these risks, and we may not be able to make
business combinations and strategic investments on terms that are acceptable to
us.

                                       8


SINCE A SUBSTANTIAL PORTION OF OUR REVENUES TO DATE HAVE COME FROM INTERNATIONAL
SALES, EVENTS AFFECTING INTERNATIONAL COMMERCE MAY ADVERSELY AFFECT OUR FUTURE
INTERNATIONAL SALES, FUTURE REVENUES AND OUR PRODUCTS' FUTURE PROFITABILITY.


International revenue accounted for approximately 37% of our total revenue in
2003, 34% of our total revenue in 2004 and 25% for the first nine months of
2005. Our key international markets are the European Union, Japan, Australia,
South Korea, Peoples' Republic of China and Canada. Outside of the European
Union, we must obtain country-by-country approval to import our products.
Fluctuations in currency exchange rates may negatively affect our ability to
compete against products denominated in local currencies. In most cases our
international sales are made through international distributors and their
wholly-owned subsidiaries with payments to us typically denominated in the local
currencies of the United Kingdom and Europe and in U.S. dollars in the rest of
the world. We believe that the U.S. is the single largest market for our EVLT(R)
product line. We anticipate that the comparative portion of our total revenues
derived from international sales will decrease as sales of our EVLT(R) product
line in the U.S. increase, with our emphasis on EVLT(R) in the U.S. However, we
expect that international sales will continue to provide a significant portion
of our total revenues.


BUSINESS INTERRUPTIONS COULD KEEP US FROM DEVELOPING OUR PRODUCTS' CLINICAL
APPLICATIONS AND INCREASING OUR REVENUES.

Natural or man-made disasters, such as fires, earthquakes, storms, power losses,
telecommunications failures, terrorist attacks, military operations, epidemics
and other events beyond our control may interrupt our operations. We do not have
a detailed disaster recovery plan. In addition, we may not carry sufficient
business interruption insurance to compensate us for losses that may occur and
any losses or damages we incur could have a material adverse effect on our cash
flows and success as an overall business.

IF WE OR OUR SUPPLIERS FAIL TO COMPLY WITH APPLICABLE MANUFACTURING REGULATIONS,
OUR BUSINESS COULD BE HARMED.

We and our key component suppliers are required to demonstrate and maintain
compliance with the FDA's Quality System Regulation, or QSR. The QSR sets forth
the FDA's requirements for good manufacturing practices of medical devices and
includes requirements for, among other things, the manufacturing, packaging,
labeling and distribution of such products. The FDA enforces the QSR through
inspections. The FDA conducted its most recent QSR inspection in 2002 and the
FDA issued a satisfactory letter to us after this inspection. We cannot assure
you that we, or our key component suppliers, are or will continue to be in
compliance or that we will not encounter any manufacturing difficulties.
Furthermore, we cannot assure you that if we need to seek new suppliers to
satisfy our business requirements, we will be able to locate new suppliers which
are in compliance with regulatory requirements. Our failure to do so will have a
material adverse effect on our ability to produce our products and on our
profitability.

MARKET ACCEPTANCE OF OUR FUTURE PRODUCTS OR THEIR USES IS UNCERTAIN. FAILURE TO
ACHIEVE MARKET ACCEPTANCE WILL HARM OUR BUSINESS' OVERALL CHANCES FOR
PROFITABILITY.

Our long term business plan envisions that we will market medical products in
addition to our current EVLT(R) and photodynamic therapy product lines. To that
end, in August 2005, we entered into an agreement with Luminetx to act as
exclusive distributor to physicians performing sclerotherapy, phlebectomies or
varicose vein treatments, in North American and the United Kingdom for a new
product, VeinViewer(TM) that Luminetx has developed. Although VeinViewer(TM) has
received FDA clearance in 2004, this product is not yet available for commercial
distribution, and its commercial acceptance has not yet been established. Other
future products will likely require regulatory approval prior to
commercialization.

Even after we or our collaborative partners obtain regulatory approval of future
products for marketing, these products may not achieve market acceptance. Our
revenues would suffer as a result. The degree of market acceptance will depend
upon a number of factors, including:

                                       9


      -the establishment and demonstration in the medical community of the
      safety and efficacy of our clinical applications and their potential
      advantages over existing applications;

      -the pricing and reimbursement policies of government and third-party
      payors, such as insurance companies, health maintenance organizations and
      other plan administrators; and

      - the general willingness of physicians, patients, payors or the medical
      community to accept, utilize or recommend any of our applications.

For example, since most photodynamic therapy treatments still are in clinical
trials, there is no long-term safety or efficacy data available. The medical
profession may, therefore, prefer to prescribe conventional alternatives to PDT,
such as surgery, chemotherapy and radiation. If our future products and clinical
applications are not accepted due to these or other factors, our business will
not develop as planned and may be harmed.

The following risks relate principally to our commercialization of our current
and future products and their clinical applications:

SOME OF OUR PRODUCTS MAY NEVER BE SUCCESSFULLY COMMERCIALIZED, AND, THEREFORE,
THESE PRODUCT LINES MAY NEVER BECOME PROFITABLE OR ALLOW US TO RECOUP EXPENSES
INCURRED IN THEIR DEVELOPMENT.

We must be able to effectively develop, market and sell our products in order to
make a profit. Commercialization depends upon:

         - successfully completing development efforts of our collaborative
            partners, including finding new clinical applications for our
            existing products;

         - obtaining the required regulatory approvals;

         - manufacturing our products at an acceptable cost and with
           appropriate quality;

         - favorable acceptance of any products marketed; and

         - successful marketing and sales efforts by our partner(s) and
           ourselves.

We may not successfully achieve some or all of these goals, and if so, our
business and our financial condition would be adversely affected. The time frame
necessary to achieve these goals for any individual clinical application is
uncertain. Most applications will require clinical studies and clinical trials,
and all applications will require regulatory approval prior to
commercialization. The likelihood of our success must be considered in light of
these and other problems, expenses, difficulties, complications and delays that
may arise.

IF WE FAIL TO GAIN MARKET ACCEPTANCE OF OUR PRODUCTS, OUR BUSINESS WOULD SUFFER.

We are introducing novel products and technology into the vein treatment market.
The vein treatment market is dominated by vein stripping procedures which are
well established among physicians, have extensive long-term data, and are
routinely taught to new surgeons. As a result, we cannot be certain of gaining
widespread acceptance of our products and therefore may not achieve expected
revenues or ever become profitable. Our principal product line, EVLR(R), is
still in the early stages of commercialization. The VeinViewer(TM) product, of
which we plan to act as an exclusive distributor to physicians performing
sclerotherapy, phlebectomies or varicose vein treatments, in North American and
the United Kingdom pursuant to an agreement with Luminetx Corporation, is a new
product which has no track record of market acceptance or profitability.

To achieve growth in sales of our product lines over time, we believe we must
continue to penetrate the market for the treatment of vein disease and expand
physicians' education with respect to the EVLT(R) product line and other lines.
Although we introduce new initiatives intended to expand physician education
from time-to-time, we cannot be assured that these innovations will be
successful.

DEVELOPMENT AND SALES OF OUR PDT PRODUCTS ARE DEPENDENT ON A NUMBER OF FACTORS
BEYOND OUR CONTROL, AND OUR ESTIMATES REGARDING OUR PDT PRODUCTS MAY BE
UNRELIABLE.

Although we currently focus on our EVLT(R) product line, our business and
results of operation may suffer if we are unable to effectively commercialize
our PDT products. Our understanding of the market for photodynamic therapy (PDT)
is derived from a variety of sources, and represents our best estimate of the
overall market size presented in certain disease areas. The actual market size
and our market share, depend upon a number of factors, including:


                                       10


      - competitive treatments, either existing or those that may arise in the
future;

      - our products' performance and subsequent labeling claims; and

      - actual patient population at and beyond product launch.

Actual results may vary from our estimates regarding these and other factors,
which could result in performance of our PDT products that differs from our
expectations.

Moreover, our sales of our PDT product line are dependent upon the clinical
development process and the commercialization of PDT drugs by photodynamic
therapy drug companies which use our PDT products in combination with their PDT
drugs. As a result, our sales may fluctuate in relation to the timing of PDT
drug companies achieving their strategic initiatives. We have limited ability to
influence the commercialization by PDT drug companies of their PDT drugs.

In addition, like any new clinical solution, PDT has to show long term results
in order to gain acceptance. The cancers that photodynamic therapy is being
developed to treat are slow to develop and acceptance of the procedure requires
long term follow up. As a result, there is currently a lack of long term
clinical data for photodynamic therapy. Furthermore, the diversity of cancers
requires us to obtain data based on each type of cancer studied. Also,
photodynamic therapy may cause a photosensitivity side effect in certain
patients such that they are highly sensitive to sunlight for several days. In
some patients this side effect may cause skin burns if the patient is exposed to
sunlight. These factors may impair our ability to develop and market our PDT
products. Other factors may slow the growth of a market for PDT procedures, and
these factors may be beyond our control.

HEALTH CARE REIMBURSEMENT FOR OUR FUTURE PRODUCTS AND THEIR APPLICATIONS REMAIN
UNCERTAIN AND WE MAY BE UNABLE TO ACHIEVE MARKET ACCEPTANCE OR GENERATE
PROJECTED REVENUES WITHOUT ROUTINE COVERAGE BY MEDICAL INSURANCE.


Our principal product line is EVLT(R). The American Medical Association and the
Center for Medicare and Medicaid Services has established reimbursement codes
for laser ablation as a mode of treatment for superficial vein disorders,
including our EVLT(R) product line for varicose veins. The new codes form the
basis for Medicare and Medicaid reimbursement across the U.S. and became
effective January 1, 2005. As a result of the creation of these codes and the
adoption of EVLT(R) by U.S. insurance carriers, as of November 30, 2005, EVLT(R)
has over 217 million covered lives in the U.S.


It still remains, however, that various health care providers and third party
payors may refuse to cover our future products and/or their particular medical
applications. If the patients who use our treatments do not obtain coverage,
patient demand for our applications may decrease and as a result, physicians may
not purchase our products. Our ability to commercialize our future products
successfully depends, in part, on the extent to which third parties make
reimbursement available for these products and related treatments. These third
parties include collaborative partners, government health administration
authorities, private health insurers, managed care entities and other
organizations. Increasingly, these payors are challenging the price of medical
products and services and establishing protocols and formularies, which
effectively limit physicians' ability to select products and procedures.
Governments may also impose restrictions on pricing or profitability of medical
devices, which could limit our potential revenue. Uncertainty exists as to the
reimbursement status of health care products, especially innovative
technologies. Additionally, reimbursement coverage, if available, may not be
adequate for us to achieve market acceptance of our future products or to
maintain price levels sufficient for us to realize an appropriate return on our
products. Additionally, Medicare and other insurance reimbursement levels could
be reduced or eliminated in the future. If payors decide not to continue
covering our products or to reduce reimbursement levels, our sales may not meet
our expectations.

Further, our strategy depends in part on our collaborative partners. As a
result, our ability to commercialize our products may be hindered if cost
control initiatives, such as reducing reimbursement rates or amounts, adversely
affect our collaborators or the clinical applications they market or are seeking
to develop.

FAILURE TO OBTAIN PRODUCT APPROVALS OR COMPLY WITH ONGOING GOVERNMENTAL
REGULATIONS COULD ADVERSELY AFFECT OUR ABILITY TO MARKET AND SELL OUR PRODUCTS
AND SERVICES AND COULD RESULT IN LOSSES.

We have been successful in receiving governmental clearances for the products
listed below along with their indications for use:

                                       11




         PRODUCT                             INDICATION FOR USE

                                             with superficial vein reflux and venous incompetence and reflux of
                                             superficial veins in the lower extremity

Diomed 15 plus and 30 plus                   Open and endoscopic surgical procedures in fields such as urology,
                                             gastroenterology, gynecology and neurosurgery; applications include
                                             treatment of vascular lesions and pigmented lesions

and D30 plus diode lasers                    vein reflux of the greater saphenous vein


The production and marketing of our products and our ongoing research and
development, preclinical studies and clinical trial activities are subject to
extensive regulation and review by numerous governmental authorities in the
United States, including the FDA, and similar regulatory agencies in other
countries. Before we can market them, most medical devices that we develop, and
all of the drugs that physicians use in conjunction with those devices, must
undergo rigorous preclinical studies and clinical trials and clear an extensive
regulatory process administered by the FDA and comparable foreign authorities.
These processes involve substantial costs and can often take many years. As a
result of the required up-front costs for regulatory approval and relatively
long time between developing a product and being able to generate revenue, we
may incur losses and negative cash flows. Regulations provide that failure to
comply with the applicable requirements can, among other things, result in
non-approval, suspensions of regulatory approvals, fines, product seizures and
recalls, operating restrictions, injunctions and criminal prosecution. We have
limited experience in performing regulatory activities, we have limited
resources available for handling regulatory matters. We rely on our
collaborative partners and outside consultants to assist us with our regulatory
needs.

We must compile and submit to the FDA and other applicable regulators new
indications of use as we determine new clinical applications for our products.
We may also be required to seek regulatory clearance for modifications to our
existing products, including changes to suppliers which must satisfy the FDA's
applicable criteria or the criteria of other applicable regulators. We believe
that we have not reached this threshold in our program and are not now required
to submit an application to the FDA for any changes we have made to our
previously reviewed products. In the future, however, we may decide to alter
certain products in a manner such that the FDA or other applicable regulators
outside the U.S. will review and approve the change. If we are required to seek
FDA approval for future indications or modifications to our existing products or
services, we or our collaborative partners may be unable to satisfy the
conditions imposed by the FDA (or other regulators). As a result, we may be
required to abandon applications for regulatory approval we make, or we may be
unable to obtain FDA clearances or other approvals we seek, and therefore we may
be unable to offer products and services relating to product modifications or
new indications of use.

We are also subject to the Radiation Control for Health and Safety Act with
laser radiation safety regulations administered by the Center for Devices and
Radiological Health of the FDA. We may be subject to fines or other penalties
for failure to comply with these regulations. For detailed information, see
"Business--Government Approvals."

SINCE TECHNOLOGY IN OUR INDUSTRY IS CONSTANTLY CHANGING, WE FACE TECHNOLOGICAL
UNCERTAINTY AND FACE CERTAIN COMPETITIVE DISADVANTAGES.

We are a relatively new enterprise and are engaged in the development of novel
therapeutic technologies, such as EVLT(R). As a result, our resources are
limited, and we may experience technical challenges inherent in such novel
technologies. Many of our competitors have substantially greater financial,
technical and human resources than we do and may also have substantially greater
experience in developing products, conducting preclinical studies or clinical
trials, obtaining regulatory approvals and manufacturing and marketing. Further,
our competitive position could be materially adversely affected if our
competitors or other third parties establish patent protection, because we may
then have to pursue alternate means of developing our products. Existing
competitors or other companies may succeed in developing technologies and
products that are safer, more effective or more affordable than those that we
develop.

IF PHYSICIANS DO NOT SUPPORT THE USE OF OUR PRODUCTS, WE MAY NOT ACHIEVE FUTURE
SALES GROWTH.

Our product sales have mainly been to physicians who are receptive to minimally
invasive techniques. Other physicians may not purchase our products until they
receive further long-term clinical evidence to convince them to alter their
existing treatment methods and recommendations from prominent physicians that
our products effectively treat vein disease. Physicians to whom we market our
products have been trained in alternative vein treatment procedures. We may be
unable to persuade physicians to incur the time or costs necessary to adopt our
EVLT(R) procedure in place of those more familiar procedures. We believe that
physicians will not use our products unless they determine, based on experience,
clinical data and other factors, that our EVLT(R) product line represents an
attractive alternative to conventional means of treating vein disease. There are
few independently published clinical reports and little long-term clinical
follow-up to support our marketing efforts. If our EVLT(R) product line does not
receive adequate endorsement by influential physicians or our long-term data
does not support our current claims of efficacy, our product sales and
profitability could be materially adversely affected. VeinViewer(TM), a new
product developed by Luminetx, of or which we will act as an exclusive
distributor to physicians performing sclerotherapy, phlebectomies or varicose
vein treatments, in North American and the United Kingdom, though cleared by the
FDA, has no track record of sales and no substantial clinical date. Therefore,
the profitability of VeinViewer(TM) for us is speculative.


                                       12


FAILURE IN OUR PHYSICIAN TRAINING EFFORTS COULD SIGNIFICANTLY REDUCE PRODUCT
SALES.

Achieving successful results with our EVLT(R) product line is highly dependent
on proper physician technique in performing the procedure. As a result, it is
critical to the success of our sales effort to provide a sufficient number of
physicians with adequate instruction in the use of our products. We rely on
physicians to spend their time to learn the new procedure. If physicians are not
properly trained, they may misuse or ineffectively use our products. This may
result in unsatisfactory patient outcomes, patient injury, negative publicity or
lawsuits against us, any of which could have an adverse effect on our product
sales or increase our product liability risk.

THE TERMINATION OF LICENSES THAT WE CURRENTLY USE COULD ENABLE COMPETITORS TO
OFFER PRODUCTS SIMILAR TO OURS OR PREVENT US FROM OFFERING OUR PRODUCTS.

We currently have two technology licenses that are material to our business. The
first license relates to our EVLT(R) product line and the second relates to our
OPTIGUIDE(R) fiber optic diffuser. For detailed information, see "Business -
Patents, Trademarks and Proprietary Technology."

We have an exclusive license to the technology we use in our EVLT(R) products
and services with four of the five inventors of this technology. We also
acquired directly from the fifth inventor all of his rights to the EVLT(R)
patent. If we were to breach our obligations under the exclusive license, our
license could be terminated by the licensor. If our license is terminated by the
licensor, although we could still make, use or sell our EVLT(R) products and
services under our own title to the EVLT(R) patent, the other inventors could
license the EVLT(R) patent to our competitors, which would reduce our
competitive advantage and could result in lower revenue.

The second license relates to our photodynamic therapy product line. This is a
sublicense for patented technology that we currently use in our OPTIGUIDE(R)
fiber optic diffuser. Our sublicense for this technology is non-exclusive. The
term of this sublicense is for the term of the primary exclusive license from
the patent owner to our licensor. The term of the primary exclusive license is
the same as the term of the patent. If our license for the OPTIGUIDE(R)
technology is terminated, we may not have access to components that we need to
manufacture our OPTIGUIDE(R) products. We may not be able to find an alternative
technology source to continue manufacturing these products on reasonable terms
or at all.

WE MAY NOT BE ABLE TO KEEP UP WITH RAPID CHANGES IN THE MEDICAL DEVICES
INDUSTRY. AS A RESULT, SOME OR ALL OF OUR PRODUCTS COULD BECOME OBSOLETE.
COMPETING PRODUCTS AND TECHNOLOGIES MAY ALSO MAKE SOME OR ALL OF OUR PROGRAMS OR
POTENTIAL PRODUCTS NONCOMPETITIVE OR OBSOLETE.

Our industry is subject to rapid, unpredictable and significant technological
change. Competition is intense. Well-known pharmaceutical and medical device
companies are marketing well-established therapies for the treatment of cancer
and other diseases. Doctors may prefer existing methods rather than try our
products. Therefore, we may be unable to meet our sales goals. Many companies
are also seeking to develop new products and technologies for medical conditions
for which we and our collaborative partners are developing treatments. Our
competitors may succeed in developing products that are safer or more effective
than ours and in obtaining regulatory approval for future products before we do.
As a result, we may not be able to recoup our costs in developing these
products. We anticipate that we will face increased competition as new companies
enter our markets and as the scientific development of similar treatments
evolves.

The following risks relate primarily to legal protections and related concerns:

THERE ARE SUBSTANTIAL CONCERNS REGARDING SAFETY AND HEALTH IN THE U.S. MEDICAL
PRODUCTS INDUSTRY. WE MAY NOT HAVE ADEQUATE PROTECTION AGAINST PRODUCT LIABILITY
OR RECALL, AND WE MAY HAVE TO PAY A SIGNIFICANT AMOUNT OF MONEY ON LIABILITY
CLAIMS OR RECALLS.

Testing, manufacturing and selling medical products and applications entails
significant inherent, industry-wide risks of allegations of product liability.
The use of our products in clinical trials and the sale of our products may
expose us to liability claims of patients or others who use our products in
connection with clinical trials or sales of treatments offered by our customers.
We currently carry insurance against these risks in amounts we believe
sufficient and comparable to other similarly situated medical device companies,
but that insurance coverage may not be adequate to cover all our liabilities.

                                       13


The following are some of the risks related to liability and recall:

      - we are subject to the inherent risk that a governmental authority or
third party may require the recall of one or more of our products;

      - if we obtain insurance coverage in the future, this coverage may not be
available at a reasonable cost, if at all, or in amounts sufficient to protect
us against claims that may be made; and

      - liability claims relating to our products or a product recall could
adversely affect our ability to obtain or maintain regulatory approval for our
products and their applications.

To date, we have been named as a defendant in one product liability action,
arising from a doctor's alleged malpractice while performing a photodynamic
therapy treatment on a patient's esophagus. That action is currently in the
discovery phase of litigation. We do not expect the outcome of this litigation
to be materially adverse to us, or to incur material expenses or liability in
connection with this action.

A successful product liability claim could materially adversely affect our cash
flows and our ability to meet the costs of developing our products and their
clinical applications. Defense of these claims could also entail significant
expense and divert the attention of our management and personnel from other
activities.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS OR
IF WE LOSE OUR INTELLECTUAL PROPERTY RIGHTS, OUR BUSINESS COULD BE ADVERSELY
AFFECTED.


We rely on a combination of patents, licenses, trade secrets and know-how to
establish and protect our proprietary rights to our technologies and products.
As of November 30, 2005, we held 23 patents in the U.S. and foreign countries.
We currently have patents for the following inventions we use in our laser
devices and systems:


      - endovascular laser treatment of varicose veins, used in EVLT(R);

      - solid state laser diode light source;

      - high power light source;

      - peltier-cooled apparatus;

      - medical spacing guide; and

      - fiber optic diffuser.

Of the patents, seven are U.S. patents and 16 are counterparts of the principal
U.S. patents filed in different jurisdictions. These patents expire at various
times from 2010 to 2019.

Included in the foregoing are patents we license. Although we have an ownership
interest in the EVLT(R) patent that we purchased in September 2003 from one of
the inventors of this technology, we also licensed the rights in the same patent
from all of the other inventors on an exclusive basis. We also sub-license
technology used in our OPTIGUIDE(R) fiber optic diffuser used in photodynamic
therapy applications on a non-exclusive basis from the licensee. For detailed
information, see the risk factor captioned "The Termination of Licenses That We
Currently Use Could Enable Competitors to Offer Products Similar to Ours or
Prevent Us from Offering Our Products" and "Business - Patents, Trademarks and
Proprietary Technology."

To date, we have sued four competitors for infringement of our EVLT(R) patent:
Vascular Solutions, Inc., AngioDynamics, Inc., Total Vein Solutions, LLC and New
Star Lasers, Inc. d/b/a CoolTouch, Inc. See "Legal Proceedings," below for
further information regarding these lawsuits. Vascular Solutions, AngioDynamics
and Total Vein Solutions have each countered that (among other things) our
EVLT(R) patent is invalid. If our EVLT(R) patent is judicially determined to be
invalid, then we will not prevail in our infringement actions. We will write off
our patent acquisition costs (currently an intangible asset on our balance
sheet) and we will not be able to exclude third parties from using our EVLT(R)
technology. This would likely have a material adverse effect on our financial
condition.

We cannot guarantee that the steps we have taken or will take to protect our
proprietary rights will be adequate to deter misappropriation of our
intellectual property. In addition to seeking formal patent protection whenever
possible, we attempt to protect our proprietary rights and trade secrets by
entering into confidentiality and non-compete agreements with employees,
consultants and third parties with which we do business. However, these
agreements can be breached and, if they are, there may not be adequate remedies
available to us, and we may be unable to prevent the unauthorized disclosure or
use of our technical knowledge, practices or procedures. If our trade secrets
become known, we may lose our competitive advantage.

                                       14


In addition, we may not be able to detect unauthorized use of our intellectual
property or take appropriate steps to enforce our rights. If third parties
infringe or misappropriate our patents or other proprietary rights, our business
could be seriously harmed. We may be required to spend significant resources to
monitor our intellectual property rights. We may not be able to detect
infringement of these rights and, consequently, we may lose the competitive
advantages associated with our intellectual property rights before we do so. In
addition, competitors may design around our technology or develop competing
technologies that do not infringe on our proprietary rights.

WE MAY BE SUBJECT TO INTELLECTUAL PROPERTY CLAIMS WHICH COULD BE COSTLY AND TIME
CONSUMING AND COULD DIVERT OUR MANAGEMENT AND KEY PERSONNEL FROM BUSINESS
OPERATIONS.

Although we do not believe that any of our products infringe the intellectual
property of third parties, we may be unaware of intellectual property rights of
others that may be used in our technology and products. Third parties may claim
that we are infringing their intellectual property rights. Third parties may
also claim that our patents have been improperly granted and may seek to
invalidate our existing or future patents. Although we do not believe that any
of our active patents should be subject to invalidation, if any claim for
invalidation prevailed, the result could result in greatly expanded
opportunities for third parties to manufacture and sell products which compete
with our products.

On July 21, 2005, VNUS Medical Technologies, Inc. ("VNUS") filed a patent
infringement lawsuit against us. We intend to vigorously defend this lawsuit.
See "Legal Proceedings," below, for further information and footnote 9 to the
September 30, 2005 Consolidated Financial Statements.

Litigation or other challenges regarding our patents or other intellectual
property could be costly and time consuming and could divert our management and
key personnel from business operations. Claims of intellectual property
infringement might also require us to enter into costly royalty or license
agreements. However, we may not be able to obtain these agreements on terms
acceptable to us, or at all. We may also be subject to significant damages or
injunctions against development and sale of our products. Infringement claims,
even if not substantiated and unsuccessful, could result in significant legal
and other costs and may be a distraction to management.

The following risks relate principally to our common stock and its market value:

OUR COMMON STOCK COULD BE SUBJECT TO SUBSTANTIAL PRICE AND VOLUME FLUCTUATIONS
DUE TO A NUMBER OF FACTORS, MANY OF WHICH WILL BE BEYOND OUR CONTROL, AND THOSE
FLUCTUATIONS MAY PREVENT OUR STOCKHOLDERS FROM RESELLING OUR COMMON STOCK AT A
PROFIT.

The securities markets have experienced extreme price and volume fluctuations
during the past three years, and the market prices of the securities of emerging
companies and technology-oriented companies have been especially volatile. In
the past, companies that have experienced volatility in the market price of
their stock have been the subject of securities class action litigation. In
fact, we were sued for allegedly violating Section 10(b) of the Securities
Exchange Act of 1934, in connection with trading activity during the first
quarter of 2002. We defended against this lawsuit and succeeded in having the
lawsuit dismissed, with prejudice. See "Legal Proceedings," below, for details
regarding this lawsuit. Securities class action litigation could result in
substantial costs, liabilities and a diversion of management's attention and
resources. The shares of common stock recently issued in our equity financing
transactions will likely enter the trading market and may result in lower
trading prices if there are not sufficient purchasers to absorb the common stock
as it enters the market.

OUR COMMON STOCK HAS BEEN PUBLICLY TRADED ONLY SINCE FEBRUARY 22, 2002. THE
PRICE OF OUR COMMON STOCK HAS FLUCTUATED WIDELY AND WE EXPECT THAT THE PRICE OF
OUR COMMON STOCK COULD CONTINUE TO FLUCTUATE SUBSTANTIALLY.

Until shortly after the February 14, 2002 merger, there was not any significant
public market for our common stock. On February 22, 2002, shares of our common
stock became listed for trading on the AMEX. We cannot be certain that the AMEX
will maintain our listing if we fall below its listing qualifications or do not
comply with other applicable AMEX rules. An issuer's securities may be delisted
by the AMEX if the issuer fails to meet certain financial criteria, or if a
listed security trades at a low market price for a substantial period of time.
We have not received notice from the AMEX threatening to delist our common
stock, but if we were to receive such a notice in the future, we cannot be
certain that we would be able to take corrective action requested by the AMEX to
avoid delisting.

If our shares are not listed on the AMEX, our shares are likely to be quoted on
the Over-the-Counter Bulletin Board of the National Association of Securities
Dealers, where they were quoted prior to February 2002, but where there may be
less trading of our shares.

                                       15


The market price for our common stock will be affected by a number of factors,
including:

      - developments within our own company;

      - our announcements of new products or new clinical applications for our
products;

      - our competitors' announcements of new products or new clinical
applications;

      - quarterly variations in our or our competitors' results of operations;

      - changes in earnings estimates, recommendations by securities analysts or
our failure to achieve analysts' earning estimates;

      - developments in our industry;

      - the number of shares of our common stock that are available for trading
in the markets at any given time; and

      - general market conditions and other factors, including factors unrelated
to our performance or that of our competitors.

In addition, the stock prices of many companies in both the medical device and
medical services industries have experienced wide fluctuations, often unrelated
to the operating performance of those companies. These factors and industry
price fluctuations may materially and adversely affect the market price of our
common stock.

CERTAIN OF OUR INVESTORS HAVE SIGNIFICANT VOTING POWER AND THESE INVESTORS MAY
ACT CONTRARY TO THE INTERESTS OF OTHER STOCKHOLDERS.

There are several investors who beneficially own significant amounts of our
common stock. As of October 31, 2005, five investors beneficially owned
approximately 56% of our common stock (on a diluted basis). See "Security
Ownership of Certain Beneficial Owners and Management," below, for further
information. These investors' interests may be different from yours. The
concentration of share ownership among a limited number of investors gives these
investors influence over our affairs, particularly if these investors act in
concert. The effect of this concentration of ownership may also delay or prevent
a change in control and might adversely affect the trading price of our common
stock. Therefore, concentration of ownership in a limited number of investors
may not be in the best interests of our other stockholders.

WE HAVE NOT PAID DIVIDENDS ON SHARES OF OUR COMMON STOCK IN THE PAST AND DO NOT
EXPECT TO PAY DIVIDENDS ON SHARES OF OUR COMMON STOCK IN THE FUTURE. ANY RETURN
ON INVESTMENT IN OUR COMMON STOCK MAY BE LIMITED TO POTENTIAL FUTURE
APPRECIATION ON THE VALUE OF OUR STOCK.

We have never paid cash dividends on shares of our common stock and do not
anticipate paying cash dividends on our common stock in the foreseeable future
(although the preferred stock we issued on September 30, 2005 provides for
dividends to be paid quarterly at varying rates - see "Liquidity and Capital
Resources; Transactions in 2005 - Private Placement Financing Completed
September 30, 2005," below, for a description of the dividend and other terms of
the preferred stock). The payment of dividends on our common stock, if ever,
will depend on our earnings, financial condition and other business and economic
factors affecting us at such time as the board of directors may consider
relevant. If we do not pay dividends, our common stock may be less valuable
because a return on investment will only occur if and to the extent that our
stock price appreciates, and, if the price of our common stock does not
appreciate, then there will be no return on investment.

A SALE OF A SUBSTANTIAL NUMBER OF SHARES OF OUR COMMON STOCK MAY CAUSE THE PRICE
OF OUR COMMON STOCK TO DECLINE AND MAY IMPAIR OUR ABILITY TO RAISE CAPITAL IN
THE FUTURE.


We have approximately 19.4 million shares of common stock outstanding as of
November 30, 2005.


If our stockholders sell substantial amounts of our common stock in the public
market, including shares issued upon the conversion of the convertible
debentures, upon the exchange of our preferred shares or on the exercise of
outstanding warrants, the market price of our common stock could decrease. These
sales also might make it more difficult for us to sell equity or equity-related
securities in the future at times and prices that we deem reasonable or
appropriate.


On October 25, 2004, we issued and sold approximately 4 million shares of common
stock in our 2004 equity and debt financing (including shares underlying
debentures converted into common stock through November 30, 2005 and warrants
exercised to purchase common stock through November 30, 2005). These 4 million
shares are included in the approximately 19.4 million shares of common stock
outstanding as of October 31, 2005. Of the securities we issued in our 2004
equity and debt financing, as of November 30, 2005, approximately 1.6 million
shares of common stock underly currently outstanding convertible debentures, and
approximately 2.7 million shares underly currently outstanding warrants. The
purchase price paid by the investors in the 2004 equity and debt financing for
shares of common stock was $1.53, the conversion price of the debentures is,
subject to certain adjustments, $2.29 per share, and the exercise price of the
warrants is, subject to certain adjustments, $2.10 per share. All of the shares
that we issued in the 2004 equity and debt financing and the shares underlying
the convertible debentures and warrants are currently registered with the SEC
and are freely tradable in the public market by the 2004 equity and debt
financing investors.


                                       16



Further, as of November 30, 2005, warrants to purchase 600,000 shares of common
stock at $2.90 per share were outstanding, 50% of which were vested. We issued
these warrants to Luminetx on August 5, 2005 pursuant to our exclusive
distribution agreement for Luminetx's VeinViewer(TM) product for which we shall
act as an exclusive distributor to physicians performing sclerotherapy,
phlebectomies or varicose vein treatments, in North American and the United
Kingdom.

Also, as of November 30, 2005, all 4 million shares of preferred stock and
warrants to purchase up to 1.8 million shares of common stock, which we had
issued on September 30, 2005, were outstanding (see "Liquidity and Capital
Resources; Transactions in 2005 - Private Placement Financing Completed
September 30, 2005," below, for further details regarding this financing). We
sold the preferred stock for $2.50 per share, and shares of preferred stock are
exchangeable for common stock at an exchange rate of $2.50 (or, on a
share-for-share basis), subject to certain adjustments. The warrants are
exercisable to purchase common stock at $2.50 per share (subject to certain
adjustments).


The terms of the preferred stock and the warrants that we issued in the
September 30, 2005 financing limit the ability of any investor to exchange
preferred stock (and for us to issue shares of common stock as dividends) and/or
exercise warrants to the extent that the shares of common stock so issued would
exceed 4.99% (or, in the case of certain investors who already owned over 4.99%
of our common stock prior to the financing, 9.99%) of the shares of common stock
outstanding, unless this limitation is waived in advance by the investor.

Assuming there is no adjustment to the exchange rate of the preferred stock or
the exercise price of the warrants, and the limitations on ownership described
above do not preclude such exchange or exercise, if the investors in the
September 30, 2005 private placement exchange all of their shares of preferred
stock for common stock and exercise all of their warrants, and if, in addition,
the debenture holders to whom we issued warrants to purchase 200,000 shares of
common stock exercise all of their warrants, then we will issue 5.8 million
shares of common stock (4 million for preferred stock and 1.8 million for
warrants). The shares issued to the investors will have an effective price per
share of $2.50. We are obligated to seek the registration with the SEC of the
shares of common stock underlying the preferred stock and warrants we sold on
September 30, 2005, whereupon these underlying shares will become freely
tradable.

According to the terms of the September 30, 2005 financing transaction, we are
subject to certain liquidated damages if we cannot obtain and maintain
effectiveness of a registration statement. Since the liquidated damages have no
contractual maximum, we determined for accounting purposes that the liquidated
damages were onerous and considered net-cash settlement of the transaction in
accordance with EITF 00-19, "Accounting for Derivative Financial Instruments
Indexed to, and Potentially Settled in, a Company's Own Stock." We recorded a
warrant liability of $1,861,328 based on the relative fair value and because the
warrants are classified as a liability; any subsequent changes in fair value
will be recorded as non-cash interest expense in our subsequent Statements of
Operations until the warrants are exercised, or expire or otherwise terminate.

If the holders of these securities are able to sell their shares of common stock
above the effective price per share paid, then they may be inclined to convert,
exchange or exercise these securities and to receive shares of common stock, and
to sell these shares. There may also be other reasons that prompt these
investors to liquidate their holdings of our securities. If these investors
determine to sell large numbers of our shares, then there may be insufficient
interest by other investors in purchasing these shares in the trading market,
which could cause the market price of our common stock to decrease.

POTENTIAL DILUTION CAUSED BY CURRENTLY OUTSTANDING STOCK OPTIONS AND WARRANTS
MAY REDUCE THE MARKET PRICE OF OUR COMMON STOCK.

As of September 30, 2005, there were outstanding stock options representing
1,711,225 shares of common stock, with exercise prices ranging from $2.00 to
$205.75 per share. The weighted average exercise price of the stock options
outstanding as of September 30, 2005 was $6.05. In addition, as of September 30,
2005, there were outstanding warrants representing 5,198,452 shares of common
stock, with exercise prices varying from $0.025 to $87.50 per share. The
weighted average exercise price of all warrants outstanding as of September 30,
2005 was $2.38 per share.

Most of our outstanding warrants provide for antidilution adjustments, which
will be triggered if we issue shares in a future transaction at an effective
price per share lower than the current exercise price of the outstanding
warrants. If triggered, these antitidilution provisions will reduce the exercise
price of the related outstanding warrants and in certain cases will also
increase the number of shares that the warrants represent so as to maintain
after the dilutive transaction the pre-transaction percentage of our shares that
the warrants represent after the transaction. These antidilution adjustments
therefore may have the effect of both lowering the effective price per share of
the shares of common stock represented by the warrants and increasing the number
of shares issuable upon exercise of the warrants, thereby both increasing the
likelihood that a warrant will be exercised and increasing the potential
dilution represented by the warrants.


In 2003, our stockholders approved an equity incentive compensation plan, which
to help incent and compensate our directors, employees and others who assist our
business, and authorized us to issue up to 1.6 million shares of common stock
(or common stock equivalents) under that plan. In 2005, our stockholders
approved an amendment to this plan, increasing the number of shares available
for grant to 3.1 million. We have granted approximatley 1.6 million stock
options under this plan as of November 30, 2005, and an additional 1.5 million
awards are available for grant under this plan. The holders of these options
have the opportunity to profit if the market price for the stock exceeds the
exercise price of their respective securities, without assuming the risk of
ownership. If the market price of the common stock does not exceed the exercise
price of these securities, then they will likely not be exercised and may expire
on their respective expiration dates.


                                       17


After the exercise of options or warrants, an increase in the number of
outstanding shares will occur, thus decreasing each shareholder's percentage of
our total outstanding equity. When the holders exercise a significant number of
these options or warrants, the market price of our stock could fall,
particularly if these holders seek to sell the underlying common stock soon
after exercising their options or warrants.

OUR CORPORATE CHARTER AND BYLAWS CONTAIN PROVISIONS THAT MAY PREVENT
TRANSACTIONS THAT COULD BE BENEFICIAL TO STOCKHOLDERS.

Our charter and bylaws restrict certain actions by our stockholders and require
greater than majority votes for certain actions. For example:

      - Only our board of directors or the chairman of the board can call
special meetings of stockholders.

      - Stockholders must give advance notice to the secretary of any
nominations for directors or other business to be brought by stockholders at any
stockholders' meeting.

      - Our board of directors has the authority to issue up to approximately 16
million additional shares of preferred stock, which are authorized under our
certificate of incorporation but are currently unissued. We currently have 4
million shares of preferred stock issued and outstanding. Our board of directors
can fix the price, rights, preferences and privileges of the preferred stock
without any further vote or action by our stockholders. These rights,
preferences and privileges attached to future preferred stock may be senior to
those of the holders of our common stock.

      - Certain stockholders hold a significant percentage of our outstanding
shares. See the risk factor entitled "Certain of Our Investors Have Significant
Voting Power and These Investors May Act Contrary to the Interests of Other
Stockholders," above.

These and other provisions of our charter, the certificates of designations
setting forth the terms of our preferred stock and our bylaws, as well as
certain provisions of Delaware law, could prevent changes in our management and
discourage, delay or prevent a merger, tender offer or proxy contest, even if
the events could be beneficial to our stockholders. These provisions could also
limit the price that investors might be willing to pay for our stock because
these provisions may limit their rights and, thus, make an investment in our
stock less attractive to prospective investors.

Additionally, the listing requirements of the AMEX, on which our common stock is
listed, provide restrictions on our ability to enter into certain types of
transactions such as the issuance of additional shares of capital stock. These
restrictions may make it more difficult to issue securities having terms
acceptable to investors in capital financing transactions that we may wish to
enter into from time to time. If we are precluded by these requirements from
issuing such securities, then our business may suffer because we will be unable
to obtain additional equity capital investment.


                                       18


          SPECIAL NOTE OF CAUTION REGARDING FORWARD-LOOKING STATEMENTS

                               RECENT DEVELOPMENTS

             PRIVATE PLACEMENT EQUITY FINANCING - SEPTEMBER 30, 2005

On September 30, 2005, we entered into and completed a private placement equity
financing transaction wherein we issued and sold to 18 accredited investors 4
million shares of preferred stock at a purchase price of $2.50 per share,
resulting in gross proceeds to us of $10 million. We agreed that the preferred
stock could be exchanged by the investors for common stock at an exchange rate
of $2.50 per share (a premium of 18% above the $2.12 closing price of the common
stock on the AMEX the trading day immediately prior to the closing of the
financing), subject to certain adjustments, and that the preferred stock could
become redeemable by the holders in certain events or by us after the preferred
stock is outstanding for at least five years, in either case with a 20% premium
over the initial purchase price. We also issued to the investors warrants to
purchase an aggregate of 1.6 million shares of common stock with an exercise
price of $2.50 per share (a premium of 18% above the $2.12 closing price of the
common stock on the AMEX the trading day immediately prior to the closing of the
financing), subject to certain adjustments, and we issued comparable warrants to
purchase an aggregate of 200,000 shares of common stock to the three holders of
convertible debentures we issued in October 2004 as an inducement for these
debenture holders to waive negative covenants that would have precluded us from
completing the financing transaction on terms that the investors required.

The registration statement of which this prospectus forms a part relates to
those shares of common stock into which the preferred stock may be exchanged, an
allotment for shares of common stock which we may issue as dividends on the
preferred stock and shares of common stock underlying the warrants we issued to
the investors and the debenture holders. The Selling Stockholders referred to in
this prospectus are the investors to whom we issued the preferred stock and

             DISTRIBUTION AGREEMENT WITH LUMINETX FOR VEINVIEWER(TM)

On August 5, 2005, we entered into a distribution agreement with Luminetx
Corporation of Memphis, Tennessee, pursuant to which Luminetx appointed us as an
exclusive distributor and granted to us the exclusive right to distribute and
sell Luminetx' patented biomedical imaging system known as the VeinViewer(TM)
Imaging System. The agreement is for an initial term of three years following
the initial date that Luminetx delivers the VeinViewer(TM) product to us, which
we expect will occur on or before January 31, 2006. The specific market covered
by this agreement includes those physicians who perform sclerotherapy,
phlebectomies or varicose vein treatments, initially in the United States and
the United Kingdom, with additional territories to be negotiated as
VeinViewer(TM) receives regulatory clearance in other countries, on terms to be
agreed.

We agreed to loan $1 million to Luminetx under the distribution agreement. We
loaned $500,000 to Luminetx on August 5, 2005 and will invest the remaining
$500,000 in Luminetx when it delivers to us a minimum number of VeinViewer(TM)
systems, as specified in our distribution agreement. We converted our $500,000
loan to Luminetx into 250,000 shares of Luminetx preferred stock, convertible
into common stock on a share-for-share basis, and warrants to purchase 50,000
shares of Luminetx common stock at $2.00 per share, exercisable for five years,
as part of an $11 million private placement financing that Luminetx announced on
November 4, 2005. We will invest the remaining $500,000 of our loan commitment
to Luminetx for preferred stock and warrants on the same terms.

We also issued warrants to purchase up to 600,000 shares of our common stock (at
an exercise price of $2.90 per share) to Luminetx as partial consideration for
granting us these exclusive distribution rights. Fifty percent of the warrants
were immediately exercisable when issued (subject to prior listing of the
underlying shares with the AMEX), and the remainder of the warrants will become
exercisable when both (i) Luminetx has produced at least 100 units of the
VeinViewer(TM) system and (ii) we have accepted delivery of at least 25 units of
the VeinViewer(TM) system. In accordance with Emerging Issues Task Force Number
96-18 "Accounting for Equity Instruments That Are Issued to Other Than Employees
for Acquiring, or in Conjunction with Selling, Goods or Services," we are
amortizing the $332,630 fair value of the distribution rights over the three
year period of the distribution agreement, commencing on the date that
distribution agreement was executed, August 5, 2005.

               DISTRIBUTION AGREEMENT WITH MED1ONLINE FOR EVLT(R)

On June 24, 2005, we entered into a distribution agreement with Med1Online, Inc.
of Golden, Colorado, pursuant to which we appointed Med1Online as our exclusive
distributor of EVLT(R) products in the OB/GYN and plastic surgery markets in the
United States. The initial term of this agreement is three years, and the
agreement is renewable annually thereafter with the parties' mutual agreement.
Med1Online will use its sales force to develop markets and improve market
penetration of EVLT(R) and provide purchase financing. We will provide
Med1Online with our promotional materials, including demos for use at mutually
agreed upon trade shows, and we will assist Med1Online in developing an in-house
sales training program and provide training for at least three Med1Online sales
representatives annually. Med1Online agreed to purchase from us a specified
minimum number of EVLT(R) lasers initially, and a minimum number of EVLT(R)
lasers each quarter in order to maintain its exclusive distribution rights.

                   LAUNCH OF NEW DELTA LINE OF EVLT(R) LASERS

Diomed has introduced a new line of lasers for use in EVLT(R) and other surgical
laser procedures. The DELTA line has improved ease-of-use, an automatic
procedure setup, a new fiber recognition system, enhanced patient data
management capabilities, and increased reliability, as compared with Diomed's
previous line of lasers. Diomed's DELTA lasers are offered in 15 and 30 watt
versions, and will replace Diomed's D15Plus and D30Plus line of lasers. The
Diomed DELTA laser became available for sale in North America and Europe
beginning November 1, 2005, and we expect the DELTA laser to become available to
the rest of our international distributor network in 2006. Meanwhile, we will
continue to sell our existing lasers platform outside of Europe. We plan to
continue to provide warranty coverage (for the remainder of warranty periods in
effect) and service support for a period of seven years from the date we
discontinue the sale of our D15Plus and D30Plus line of lasers.

            do not owe the investors more than $15,000, in the aggregate, under
            the transaction documents for the private placement financing.

                                    BUSINESS

                            OVERVIEW OF OUR BUSINESS

We develop and commercialize minimally invasive medical procedures that employ
our laser technologies and associated disposable products. Using our proprietary
technology, including our exclusive rights to U.S. Patent No. 6,398,777, we
currently focus on endovenous laser treatment (EVLT(R)) of varicose veins. We
also develop and market lasers and disposable products for photodynamic therapy
(PDT) cancer procedures and products for other clinical applications, including
dental and general surgical procedures. We carry on our business primarily
through our wholly-owned subsidiaries, Diomed, Inc. and Diomed, Ltd.

In developing and marketing our clinical solutions, we use proprietary
technology and aim to secure strong commercial advantages over competitors by
obtaining exclusive commercial arrangements, gaining governmental approvals in
advance of others and developing and offering innovative practice enhancement
programs, including physician training and promotional materials. To optimize
revenues, we focus on clinical procedures that generate revenues from both
capital equipment and disposable products, such as procedure kits and optical
fibers.

Our high power semiconductor diode lasers combine clinical efficacy, operational
efficiency and cost effectiveness in a versatile, compact, lightweight,
easy-to-use and easy-to-maintain system. Along with lasers and single-use
procedure kits for EVLT(R), we provide our customers with state-of-the-art
physician training and practice development support.

In 2001, we pioneered the commercialization of endovenous laser treatment
(EVLT(R)), an innovative minimally invasive laser procedure for the treatment of
varicose veins caused by greater saphenous vein reflux. In September 2001, we
were the first company to receive the CE mark of the European Economic Union for
approval for endovenous laser treatment with respect to marketing EVLT(R) in
Europe. In January 2002, we were the first company to receive FDA clearance for
endovenous laser treatment of the greater saphenous vein. In December 2004, we
received FDA clearance to expand the application of EVLT(R) to other superficial
veins in the lower extremities.

EVLT(R) was our primary source of revenue in 2004, and will continue to be a
primary source of revenue in 2005. We believe that EVLT(R) will achieve a high
level of commercial acceptance due to its relative short recovery period,
immediate return to the patient's normal routine barring vigorous physical
activities, reduced pain and minimal scarring and reduced costs compared to
other treatments for varicose veins. We developed our EVLT(R) product line as a
complete clinical solution and marketing model, including a laser, disposable
kit, clinical training, customized marketing programs plus other complimentary
products that support our basic EVLT(R) strategy, to assist office-based and
hospital-based physicians in responding to the growing demand for treatment of
varicose veins in a minimally invasive manner. We have also published a health
insurance reimbursement guide to assist physicians in the reimbursement
submission process. We believe that these attributes, in addition to EVLT(R)'s
superior clinical trial results, favorable peer reviews and comparatively larger
and longer follow-up data reports provide EVLT(R) with a competitive advantage
over competing traditional and minimally invasive varicose vein treatment
products.

                                       22


We expect that as the number of EVLT(R) procedures increases, so will our sales
of associated disposable items. We believe that the U.S. represents the single
largest market for EVLT(R). We target our sales and marketing efforts at
hospitals, private physician practices and clinics and focus on specialists in
vascular surgery, interventional-radiology, general surgery, phlebology,
interventional cardiology, gynecology and dermatology.

We primarily utilize a direct sales force to market our products in the United
States and a network of more than 30 distributors to market our products abroad.
In June 2005, we entered into an exclusive distribution agreement with
Colorado-based Med1 Online, Inc., a leading online distributor of capital
medical equipment in the United States. Under the terms of the three-year
renewable distribution agreement, Med1Online acquired exclusive distribution
rights to market our EVLT(R) product line to the OB/GYN and plastic surgery
physician market segments in the United States. We currently employ 19 EVLT(R)
sales representatives, two regional sales managers and four clinical
specialists, including one training manager, in support of our field sales
efforts. These clinical specialists assist in physician training and post-sales
support, freeing our sales representatives to focus on new sales opportunities.
We plan to fill one open sales territory.  We hired two sales development
personnel to focus on VeinViewer(TM) sales and plan to hire one more.

We have developed and maintain a website - www.EVLT.com - to assist both
patients and physicians. EVLT.com provides patients with education about
treatment options and benefits of EVLT(R) and provides physicians with education
about the EVLT(R) procedure. At www.EVLT.com, patients can also locate the
nearest physician performing EVLT(R) by inputting their city and state. We also
maintain a corporate website - www.diomedinc.com - to provide information about
us and our physician support iniatives, among other things.

We currently focus on the development and growth of EVLT(R) sales both
domestically and internationally. We also plan to expand our product offerings
to include VeinViewer(TM) to physicians performing sclerotherapy, phlebectomies
or varicose vein treatments, in North American and the United Kingdom under our
exclusive distribution agreement with Luminetx (see "Recent Developments -
Distribution Agreement with Luminetx for VeinViewer(TM)," above). We also
support the development and approval of new applications for PDT products and
the development of enhancements to our products in order to further improve
their quality, effectiveness and manufacturability. Our management team focuses
on developing and marketing solutions that address serious medical problems that
have significant markets. Our determinations are based upon the number of
procedures that may be conducted in a market and projections of the associated
revenue. Currently, EVLT(R) applications fall within this guideline, and we
believe that photodynamic therapy may have the potential to do so as well at
some time in the future. However, EVLT(R), and not PDT, is the emphasis of our
current business plan.

                              HISTORICAL BACKGROUND

Diomed, Inc. was incorporated on December 24, 1997 in the State of Delaware. On
June 23, 1998, Diomed, Inc. succeeded to the business of Diomed, Ltd., a company
formed under the laws of the United Kingdom in 1991. It did so by issuing shares
of Diomed, Inc. on a one-to-one exchange basis to the holders of the shares of
Diomed, Ltd. As a result of the exchange, Diomed, Inc. became the owner of 100%
of the outstanding shares of Diomed, Ltd., and Diomed, Ltd. became a
wholly-owned subsidiary of Diomed, Inc. Diomed, Ltd. continues to operate in the
United Kingdom. Its chief activities are product development, manufacturing and
international sales and marketing.

Since our inception in 1991 in Cambridge, England, we have focused on the
development of medical diode lasers. Our proprietary diode laser technology has
made it possible to simplify and minimize certain medical procedures. Utilizing
our core competency in diode light sources and optical fibers, we pioneered the
development of diode lasers for medical applications, first with photodynamic
therapy and later with EVLT(R).

In November 2000, to enter the disposable market segment of our laser business,
we acquired the medical fiber business of QLT, Inc., a company based in
Vancouver, British Columbia. We acquired QLT's rights to manufacture and market
OPTIGUIDE(R) fibers that were developed for use in photodynamic therapy cancer
treatments and the distribution rights to customers of Laserscope and Coherent,
Inc., two manufacturers of medical laser devices.

In the fourth quarter of 2000, we also created FibersDirect.com, a U.S. business
unit we use as direct marketing conduit by providing on-line information for a
number of our products and an e-mail link to our sales staff. FibersDirect.com
enables distribution of fibers directly from the manufacturer to the end-user.
Our OPTIGUIDE(R) fibers used in photodynamic therapy cancer treatments are
promoted via FibersDirect.com.

                                       23


Diomed, Inc. is now a subsidiary of Diomed Holdings, Inc., a corporation
originally formed under the laws of the State of Nevada on March 3, 1998 under
the name Natexco Corporation. On February 11, 2002, we changed our name from
Natexco Corporation to Diomed Holdings, Inc. On February 14, 2002, Diomed
Holdings, Inc. acquired Diomed, Inc. in a reverse merger, pursuant to the terms
of an Agreement and Plan of Merger. We refer to the reverse merger that occurred
on February 14, 2002 as the "Merger." As a result of the Merger, Diomed, Inc.
became a wholly-owned subsidiary of Diomed Holdings, Inc., and the business of
Diomed Holdings, Inc. is now principally the business of Diomed, Inc.
Accordingly, except for this section or as otherwise indicated, the discussion
of our business relates to Diomed, Inc.'s business. The principal purpose of the
Merger was to enhance our ability to raise capital for our business by creating
a public trading market for shares of our common stock.

For financial statement purposes, the Merger was treated as a recapitalization
of Diomed, Inc. For tax purposes, we believe the Merger qualifies as a tax-free
exchange of equity securities. We have not, however, requested any ruling from
the Internal Revenue Service in respect of the tax treatment of the Merger. For
detailed information, see Note (8) of the Notes to our December 31, 2004 Audited
Consolidated Financial Statements.

In April 2002, our board of directors determined that it was in our best
interests and the best interests of our stockholders to change our state of
incorporation from Nevada to Delaware by way of the migratory merger. On May 13,
2002, after obtaining stockholder approval, we completed the migratory merger by
merging Diomed Holdings, Inc. (Nevada) with and into a newly organized Delaware
subsidiary, Diomed Holdings, Inc. (Delaware).

Since we have become a Delaware corporation, we and our stockholders are subject
to Section 203 of the General Corporation Law of the State of Delaware, an
anti-takeover law. In general, the law prohibits a public Delaware corporation
from engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
the prescribed manner. A "business combination" includes a merger, asset sale or
other transaction resulting in a financing benefit to the interested
stockholder. An "interested stockholder" is a person who, together with
affiliates and associates, owns (or within the prior three years, did own) 15%
or more of the corporation's voting stock.

For detailed information, see "Description of Securities - Recent Sales of
Unregistered Securities," and Note (8) of the Notes to the December 31, 2004
Audited Consolidated Financial Statements.

                                BUSINESS STRATEGY

At our inception in 1991 in Cambridge, England, we focused on the development of
medical diode lasers and their applications. Since that time, we have advanced
that technology and expanded its application through internal development
efforts, strategic business combinations and intellectual property acquisition.
We have sourced our products through external and internal manufacturing
capabilities and distributed our products through a combination of both a direct
sales organization and indirect distributors.

        FULL SERVICE DIFFERENTIATION TO MAXIMIZE REVENUE AND MARKET SHARE

We generate revenues from the sale of our products and services. We launched our
EVLT(R) product line in the U.S. after receiving FDA clearance in January 2002,
and, in mid 2002, we established a direct sales force to focus on EVLT(R) sales.
Our sales force concentrates on selling our EVLT(R) products and, to a lesser
extent, our photodynamic therapy product line, along with complimentary products
for adjunct procedures. Our direct sales force is well trained and versed in
selling EVLT(R) as a complete clinical solution for the treatment of varicose
veins. Our clinical solution includes both the laser and disposable procedure
kits, along with physician training and practice management tools which we
provide to help physicians develop and manage his or her EVLT(R) business. In
addition, we have developed a website, www.evlt.com, to provide patients and
physicians with information about treatment options and benefits of EVLT(R).
International sales are managed through a global network of third party sales
agents and distributors.

   RESEARCH AND DEVELOPMENT TO ENHANCE EFFICIENCIES AND PRODUCT EFFECTIVENESS

We have an internal research and development staff and from time to time have
used outside experts to assist us in our product development program.
Historically, our research and development efforts concentrated on the
development of clinical applications and solutions for our lasers and related
delivery systems. Through these past efforts, we have commercialized our EVLT(R)
and photodynamic therapy product lines. Although current research and
development activities are directed at enhancing our laser and fiber
manufacturing efficiency and the functional effectiveness of our EVLT(R) product
line, we are continuously evaluating new clinical applications and solutions for
our lasers and delivery systems.

                                       24


                    KEY ACQUISITIONS TO ENHANCE PROFITABILITY

On September 3, 2003, we acquired exclusive rights to U.S. Patent No. 6,398,777
and foreign counterparts regarding the endovenous laser treatment of varicose
veins from the five inventors of this procedure. With this proprietary position,
we believe we have positioned ourselves to be the leader in minimally invasive
varicose vein treatment. Previously, in November 2000, we acquired the rights to
manufacture OPTIGUIDE(R) fiber from QLT, Inc. We periodically entertain
attractive opportunities in related fields and we expect to continue efforts to
identify and pursue these opportunities in 2005. In August 2005, we entered into
an exclusive distribution agreement for Luminetx's new VeinViewer(TM) to
physicians performing sclerotherapy, phlebectomies or varicose vein treatments,
in North American and the United Kingdom (see "Recent Developments -
Distribution Agreement with Luminetx for VeinViewer(TM)," above).

                  STRATEGIC ALLIANCES TO ENHANCE CUSTOMER REACH

We have established strategic alliances with some notable photodynamic therapy
drug companies to bring new treatments to market. However, the underlying
products being developed by these companies which are used in conjunction with
our products, have gained only limited regulatory approval required for
commercialization, and expanded regulatory approval is not assured. Accordingly,
we have focused our near-term investment in the commercialization of EVLT(R). In
addition, we maintain original equipment manufacture ("OEM") relationships with
companies such as Olympus in Japan, which uses our technology for surgical and
dental applications, and with Dentek Medical Systems GmbH, which uses our laser
module for dental applications. Our strategy is to create long-term and
exclusive working relationships that increase laser applications and revenue
potential through the sale of our lasers and disposables whenever possible.

                 PRODUCTS, COMPETENCIES AND MARKET OPPORTUNITIES

Our focus on the development and commercialization of minimally and
micro-invasive medical procedures employing our laser technology and disposable
products has led to an array of applications. Minimally and micro-invasive
medical procedures in general are a growing market, as they reduce the need for
general anesthesia, expensive hospital stays and long and painful recovery
periods. We address medical procedures which we believe are capable of producing
a recurring revenue stream through the sale of a disposable, such as a procedure
kit or individual fiber, in addition to one-time revenue from the sale of the
laser product itself. In 2003, 62% of our total revenues were derived from laser
sales and 38% of our total revenues were derived from sales of disposable fibers
and kits, accessories and services. In 2004, 59% of our total revenues were
derived from laser sales and 41% of our total revenues were derived from sales
of disposable fibers and kits, accessories and services. For the first two
quarters of 2005, approximately 51% of our total revenues were from laser sales
and approximately 49% of total revenues were from sales of disposable products.

ENDOVENOUS LASER TREATMENT

In September 2001, we were the first company to receive the CE mark of the
European Economic Union for approval for marketing endovenous laser treatment,
with respect to marketing EVLT(R) in Europe. The following January, we became
the first company to receive FDA clearance for endovenous laser treatment for
the closure of the greater saphenous vein with superficial reflux. In December
2002, we received FDA clearance for expanded indications for use of EVLT(R),
including our D15plus and D30plus diode lasers and disposable kits for the
treatment of varicose veins and varicosities associated with the superficial
vein reflux of the greater saphenous vein. In December 2004, we obtained FDA
clearance authorizing the use of our laser and procedure kits for treatment of
venous incompetence and reflux of other superficial veins in the lower
extremity.

On September 3, 2003, we acquired exclusive rights to the patent for endovenous
laser treatment of varicose veins from the five inventors of this procedure. For
detailed information, see "Patents, Trademarks and Proprietary Technology,"
below.

We commercialized EVLT(R) as an innovative minimally invasive laser procedure
for the treatment of varicose veins resulting from reflux of the greater
saphenous vein. The causes of varicose veins are commonly genetic. People with
past vein diseases, new mothers, overweight individuals and people with jobs or
hobbies that require extended standing also are at risk. According to a 1973
report by the University of Michigan under a comprehensive study of the health
characteristics of the community of Tecumseh, Michigan, approximately 25% of
women in the U.S. have varicose veins. In addition, varicose veins are more
prevalent in older people. The Tecumseh study was a comprehensive longitudinal
research study that tracked the health of a sample population of 7,000 to nearly
9,000 people at three intervals over the course of a decade, from the late 1950s
to the late 1960s. According to the Tecumseh study, at least 42% of Americans
over age 60 have varicose veins and this number is increasing as the population
continues to age. The Tecumseh study also indicates that at least 72% of women
over age 60 in the U.S. have varicose veins. According to the American
Association of Retired Persons, approximately 76 million people in the U.S. are
50 or older, and approximately an additional 4 million people turn 50 each year.

We estimate that there are currently 25 to 40 million Americans who suffer from
some degree of venous insufficiency and that there are approximately 150,000
people in the U.S. and 1 million people worldwide who undergo vein stripping
operations annually. We also believe that many people forego vein stripping
procedures to treat their venous insufficiency due to the pain, extended
recovery time, significant potential of scarring and other serious side effects
associated with vein stripping. We believe that most patients who undergo
vein-stripping procedures are candidates for endovenous laser treatment. EVLT(R)
has several competitive advantages over the current vein-stripping treatment.

                                       25


The EVLT(R) procedure takes approximately 45 minutes per leg and was developed
to be performed in a physician's office, usually under local anesthesia and with
the procedure guided by ultrasound technology. EVLT(R) also has a fast recovery
period, reduced or minimal pain and no appreciable scarring. In endovenous laser
treatment, the area of the leg affected is anesthetized locally and a thin laser
fiber is inserted into the effected vein to deliver the laser energy in short
pulses or as a continuous application. At the end of the procedure, after the
fiber is withdrawn, a compression bandage is applied and worn up to three days.
In addition, a compression stocking is worn for seven to 14 days. Patients can
resume their normal routine, barring vigorous physical activities, directly
after undergoing the treatment.

Vein stripping is a surgical procedure that typically requires general
anesthesia, an overnight hospital stay, a painful recovery period of several
weeks, and possibly post-operative scarring and post-operative infections from
incisions. During clinical studies, up to 98% of first-time EVLT(R) treatments
in clinical trials have been successful. A follow-on EVLT(R) treatment has
successfully resolved the remaining cases. Vein stripping has demonstrated long
term efficacy rates as low as 65%.

We developed our EVLT(R) product line as a complete clinical solution and
marketing model, including a laser, disposable kit and a training and marketing
plan to assist physicians, clinics and hospitals in responding to the demand for
treatment of varicose veins. EVLT(R) is attractive to physicians because of its
high efficacy, low complication rate, low patient cost (relative to vein
stripping) and favorable practice return on investment. Also, EVLT(R) for
treatment of greater saphenous vein reflex is considered a non-cosmetic
procedure that is now reimbursable for over 217 million covered lives.

A study co-authored by Dr. Robert Min entitled "Endovenous Laser Treatment of
Saphenous Vein Reflux: Long-Term Results," was published in the August 2003
issue of the Journal of Vascular and Interventional Radiology. The study shows
what we believe to be excellent long-term results for the successful occlusion
of varicose veins caused by reflux of the greater saphenous vein. The data
presented in the study shows that minimally invasive laser treatment of varicose
veins has a high long-term success rate, low complication rate and rapid
recovery. The Cornell study included 499 limbs with varicose veins treated by
EVLT(R) over a three-year period. Patients were evaluated clinically and with
duplex ultrasound scans at 1 week, 1 month, 6 months, 12 months, 24 months, and
36 months to assess efficacy and adverse reactions. Successful occlusion of the
greater saphenous vein after initial treatment was 98.2% and, at 2 year
follow-up, 93.4% remain closed (113 of 121 limbs followed for 2 years).
Importantly, all recurrences occurred prior to 9 months with the majority noted
less than 3 months following endovenous laser treatment.

The study described above was recently updated in an article authored by Dr. Min
published in the August 2005 issue of the Journal of Cardiovascular Surgery
(Vol. 46, No. 4, pp. 395-405, Aug. 2005). The article states that "successful
endovenous laser treatment . . . was seen in 98% (982/1000) [of] treated limbs
with follow-up between 1 and 5 years . . . 457/460 or 99% of treated veins
remain occluded at 2-5 year follow-up," and "13/18 treatment failures
noted occurred prior to one year." Of note, the study reports only one failure
in 500 limbs after instituting several procedural modifications that include
delivering 14W of energy with a continuous pullback rate (rate of energy
delivery along the length of vein) of 1-3 mm per second.

In this study, there were no reports of skin burns, no abnormal nerve sensation
and no deep vein clots. In comparison, traditional surgery (ligation and
stripping) often requires general or spinal anesthesia and can take up to 4
weeks for full recovery. Pain, bruising and scarring are also common. The
results in this study also show EVLT(R) to be comparable or superior to those
reported for other options available for treating greater saphenous vein reflux,
including ultrasound guided sclerotherapy, and radiofrequency ablation. Dr. Min
is the Director of Cornell Vascular in New York and Vice-Chairman of Radiology
at Weill Medical College of Cornell University. Dr. Min is an inventor of the
EVLT(R) treatment, who sold his rights to this patent to Diomed on September 3,
2003. Dr. Min also assists Diomed in physician training and in the development
of medical treatments using EVLT(R). According to the terms of our patent
purchase agreement with Dr. Min, we pay Dr. Min variable payments, based on our
sales of products using the EVLT(R) patent. He has been a paid consultant to us
since August 2001 and, as of December 31, 2004, owns options to purchase 41,391
shares of common stock.

EVLT(R) was a primary source of revenue in 2004, and continues to be our primary
source of revenue in 2005. We believe that EVLT(R) will achieve a high level of
commercial acceptance due to its high efficiency, low rate of complications,
short recovery period, reduced pain and minimal scarring and reduced costs
compared to other treatments for varicose veins. As of September 30, 2005, we
have sold nearly 800 EVLT(R) lasers, and have established Diomed as the leading
brand of endovenous laser treatment products for varicose veins. We expect that
as the volume of EVLT(R) procedures performed increases so may our disposable
sales. We believe that for the foreseeable future the U.S. represents the single
largest market for EVLT(R).

CANCER TREATMENTS UTILIZING PHOTODYNAMIC THERAPY

We were the first diode laser manufacturer to receive FDA clearance for use of
our lasers and optical fibers in photodynamic therapy cancer treatments.
Photodynamic therapy (PDT) is an effective palliative treatment for late-stage
lung and esophageal cancers and is under study for treatment of various other
cancers throughout the body. Photodynamic therapy is based on the discovery that
certain chemicals can kill one-celled organisms in the presence of light. Recent
interest in photosensitizing agents stems from research showing that some of
these substances have a tendency to collect in cancer cells.

When using PDT, the photosensitizing agent injected into the body is absorbed by
all cells. The agent remains in or around tumor cells for a longer time than it
does in normal tissue. When treated cancer cells are exposed to light from a
laser, the light is absorbed by the photosensitizing agent. This light
absorption causes a chemical reaction that destroys the tumor cells. Light
exposure is carefully timed to coincide with the period when most of the agent
has left healthy cells but still remains in cancer cells.

There are several promising features of photodynamic therapy in treating cancer:
(1) cancer cells can be selectively destroyed while most normal cells are
spared, (2) the damaging effect of the photosensitizing agent occurs only when
the substance is exposed to light and (3) the side effects are relatively mild.
The laser light used in photodynamic therapy is directed through an optical
fiber. The optical fiber is placed close to the cancer to deliver the proper
amount of light. For example, the fiber optic can be directed through a
bronchoscope into the lungs for the treatment of lung cancer or through an
endoscope into the esophagus for the treatment of esophageal cancer.

Our photodynamic therapy product line of photodynamic therapy solutions uses our
own proprietary laser technology. When used in combination with a
photosensitizing drug, photodynamic therapy provides the cancer therapy. As
indicated, photodynamic therapy requires three-interacting elements: (1) a
photosensitive drug that is absorbed by cancerous and abnormal cells, (2) a
light source (laser) of a specific wavelength that activates the drug and (3) a
delivery system, including a thin optical-fiber to guide the light source to the
target area. Photodynamic therapy technology is only effective when these three
components are working in concert. We have worked early in the clinical
development process with photodynamic therapy drug companies to design a laser
that optimizes the most effective wavelength in combination with their
photodynamic therapy drugs.

In the U.S., regulatory approval by the FDA is given for each specific treatment
in response to a specific pre-market approval application. Each pre-market
approval application is generally addressed to a use for the device that the
pre-market approval application specifies. The FDA considers photodynamic
therapy a modality that requires a combination pre-market approval application,
where the photodynamic therapy drug company, laser manufacturer and fiber
manufacturer work together to obtain regulatory approval for the complete
medical procedure. The lengthy regulatory approval process and FDA modality
factor create significant obstacles to potential competition.

In August 2000, we and Axcan Pharma together received regulatory approval for
our 630nm laser and OPTIGUIDE(R) fiber, and Axcan Pharma's Photofrin(R) drug
used in the palliative treatment for late stage lung and esophageal cancers. In
November 2000, we entered into a 5-year exclusive supply contract with Axcan
Pharma for lasers. Axcan Pharma is developing other clinical applications using
Photofrin(R), including treatment for Barrett's Esophagus, a pre-cursor to
cancer of the esophagus. Axcan Pharma has pursued an application for FDA
clearance for Photofrin(R) and our lasers and fibers for use in the treatment of
Barrett's Esophagus. In December 2002, the FDA issued an approvable letter in
connection with Axcan Pharma's application. Axcan Pharma announced that it
received FDA clearance for the photodynamic therapy for Barrett's Esophagus in
August 2003. In September 2004, our laser development and supply agreement with
Axcan Pharma, dated August 2, 2000, was terminated and as a result, we are no
longer distributing PDT lasers through Axcan Pharma. Sales to Axcan Pharma
represented approximately 1% or less of our sales in 2003 and 2004. We expect to
continue to market PDT lasers through our direct sales force and distributors,
both domestically and internationally.

We currently believe that the potential market for our EVLT(R) product line is
substantially larger than the potential market for our photodynamic therapy
product line. We also expect sales of EVLT(R) products and services to account
for an increasingly higher proportion of our total sales revenue as compared to
photodynamic therapy products. Therefore, while we continue to pursue sales of
our photodynamic therapy product line and to pursue development of new
photodynamic therapy applications through the efforts of our collaborative
partners, our present emphasis is on our EVLT(R) product line and we are
concentrating our marketing and sales efforts towards the EVLT(R) product line.

FIBERS AND DISPOSABLE ITEMS

To address medical conditions with minimally invasive techniques, we offer
physicians an integrated clinical solution, including a laser and disposable
procedure kits or individual fibers. Optical fiber is the necessary system that
delivers the laser light during surgical, endovenous laser treatment and
photodynamic therapy procedures. These sterile fibers, generally used only once
to ensure sterility, can generate a steady stream of revenue. We sell
self-contained EVLT(R) kits of disposable items, which include an optical fiber,
a sheath that acts as an introduction for the fiber, a needle, a guidewire, a
tray cloth and protective packaging. In some cases, we sell only the fiber.

The potential market for kits, fibers and other disposable items is driven by
the adoption rate of the specific clinical procedure. We have and will continue
to generate a disposable market by developing and promoting specific procedures,
such as endovenous laser treatments. As EVLT(R) gains market share in comparison
to vein-stripping and other varicose vein procedures, so will the volume of kits
and fibers used in these treatments, and the volume of fibers we sell for use in
these procedures is expected to increase.

                                       27


OTHER CLINICAL APPLICATIONS

Our technologies are also used in general surgical applications as well as in
dental applications. While our focus is on the development of specific clinical
applications, such as varicose vein treatment with EVLT(R), other medical
applications can be, and are being, performed with our lasers. For instance, the
FDA has also cleared our diode laser technology for open and endoscopic surgical
procedures, which are used to treat vascular and pigmented lesions. Potential
clinical applications that we may address include:

Nasal Polypectomy: Nasal polyps are usually benign growths in the nose, which
are removed with the laser with minimal bleeding and quick recovery period.

Turbinate Reduction: The turbinates are structures in the nose which can become
enlarged due to conditions such as allergies and obstruct the airways. The laser
can be used to reduce their size and clear the blockage. Other nasal procedures
include: ethmoidectomy, meatal antrostomy, maxillary endo-sinus surgery. These
various procedures involve the removal of blockages, opening up of the various
airways and gaining access to various structures within the nose.

Dacryocystorhinostomy (DCR): Tear ducts take tears from the corner of the eye
down into the nose. Blockage of the tear ducts results in watery eyes. The laser
fiber can be used to reopen the channel from the tear duct into the nose and
resolve the problem. This simple procedure can be performed under local
anesthetic, is less traumatic than conventional surgery and leaves no surgical
scarring.

Ontological Surgery: By carbonizing the end of the fiber, the trapped laser
energy heats up the tip producing in effect a tiny "hot knife", which can be
used, for cutting away tissue in a variety of conditions in the ear. The fine
tip size makes it an exceptionally controllable tool. Applications include
Stapedotomy and Stapedectomy (treatments involving the auditory bones in the ear
to correct hearing problems), Myringotomy (incision in eardrum to relieve
pressure from infection), Cholesteatoma and Acoustic neuron (benign growths in
the ear which are removed).

Uvulopalatoplasty (LAUP): Reshaping of the soft palate and uvula at the back of
the mouth is done in severe cases to reduce snoring and can be performed in one
session using a fine sculpted tip fiber. The coagulated area surrounding the
incision ensures virtually no blood loss, faster patient recovery and minimal
post-operative nursing requirements.

Vaporization of Tumors: Areas of abnormal tissue due to inflammation or
infection can be destroyed or reduced in size with heat energy. The laser
delivers this in a very controllable way with a known depth of effect, which
avoids damage to surrounding structures.

Gastro-Intestinal Cancer: Cancer in the gullet will grow and block the tube
stopping the patient from swallowing. The cancer can be reduced in size and the
tube reopened using the laser. This relieves the symptoms allowing the patient
to eat relatively normally, often returning home. It does not cure the cancer
but produces a temporary improvement in quality of life.

Lung Tumors: Cancers in the lung will grow and obstruct the airways causing
breathing problems for the patient. The cancer can be reduced in size and the
airway reopened using the laser. This relieves the symptoms allowing the patient
to breathe more normally. Again, this treatment does not cure the cancer, but
produces a temporary improvement in quality of life.

Vascular Lesions: Although seen as primarily a cosmetic problem, vascular and
pigmented lesions can have a profound effect on lifestyle especially when they
occur in young people. For many years lasers have been used to treat such
lesions with a high degree of success. Such procedures are simple to perform and
the nature of the laser light allows for a high degree of precision while
minimizing side effects. The laser can be used by shining it through the skin
(transdermally) to reduce the lesions' appearance. Delivery of the laser energy
is simplified by a range of specially designed hand pieces.

Neurosurgery: There are a variety of intercranial tumors which can be treated
with the laser. Those most suitable for laser assisted ablation are the benign
forms especially the various meningiomas. The laser can also be useful in
gaining access to lesions involving the brain stem and for removing acoustic
neuromas. The hemostatic properties of the laser, its controllability and the
limited collateral effects make the laser highly suitable for neurosurgical
applications.

Urology: The laser can be used in the treatment of Benign Prostate Hypertrophy
(BPH) in three different ways. It can be used transurethrally to debulk the
prostate by contact tissue removal or by non-contact tissue coagulation. It can
also be used to shrink the prostate by interstitial therapy. In addition, the
laser can be used to destroy bladder tumors and for a variety of open surgical
techniques where its ability to cut and coagulate simultaneously are utilized.

Interstitial Therapy: The laser can be used to treat tumors within normal tissue
by thermally destroying them in situ. This technique is applicable to liver
metastases, osteoid osteomas and breast tumors. In addition, the laser can be
used in a similar way on the nucleus pulposus to cause shrinkage and reduce
pressure within the discs of the lower back. This latter technique is called
Percutaneous Laser Disc Decompression (PLDD).

                                       28


There are numerous processes for the development of products for these potential
clinical applications. In general, however, each of them will require extensive
preclinical studies, successful clinical trials and cleared pre-market approval
applications or 510(k)s before they can generate significant revenues. We
currently have no pending regulatory applications or clinical studies. We may
rely on third parties, including our collaborative partners, to design and
conduct any required clinical trials. If, we are not able to find appropriate
third parties to design and conduct clinical trials, and if we do not have the
resources to administer clinical trials in-house, this process may become even
more lengthy and expensive. Since we collaborate with third parties, those
parties generally maintain certain rights to control aspects of the application
development and clinical programs. Our business depends in part on our ability
to obtain regulatory approval for expanding applications and uses of our
products. Therefore, delays or other related problems may adversely affect our
ability to generate future revenues.

We may rely on third parties, including our collaborative partners, to design
and conduct any required clinical trials. In the future, we may not be able to
find appropriate third parties to design and conduct clinical trials or we may
not have the resources to administer clinical trials in-house. Therefore, this
process may become even more lengthy and expensive. Moreover, our collaborative
partners have certain rights to control aspects of the application development
and clinical programs. As a result, these programs might not be conducted in the
manner we currently contemplate. Since our business' success is heavily
dependent upon our ability to achieve regulatory approval for the applications
and uses of our products, our revenues may be adversely affected by delays or
other related problems.

Data already obtained from preclinical studies and clinical trials of our
products under development does not necessarily demonstrate that favorable
results will be obtained from future preclinical studies and clinical trials. A
number of companies in the medical devices industry, as in the pharmaceutical
industry, have suffered setbacks in advanced clinical trials, even after
promising results in earlier trials.

ORIGINAL EQUIPMENT MANUFACTURING

Our technology and manufacturing capability has attracted original equipment
manufacturing (OEM) partners. In the typical original equipment manufacturing
relationship, we produce the laser and other products to the original equipment
manufacturing customer's specifications, which will then be marketed under the
original equipment manufacturing's label. Our most significant original
equipment manufacturing relationship is with Olympus in Japan, which is using
our technology for surgical and dental applications. Our OEM business
represented approximately 5% to 7% of total revenues in 2004 and 2003,
respectively, and we expect it to continue to decline as a percentage of sales.

                                  MANUFACTURING

We manufacture our lasers with components and subassemblies that our
subcontractors supply. We assemble and test each of our lasers at our Cambridge,
England facility. Ensuring adequate inventory, continuous cost reduction and
superior product quality are top priorities of our manufacturing operations. To
achieve our goals, we work closely with our research and development, sales and
marketing teams, and effectively manage a limited number of what we believe to
be the most qualified suppliers.

We use a variety of materials, including mechanical, electronic, optical
components and subassemblies for the lasers, plus other materials that our
customers purchase for direct consumption, such as disposable items sold in kit
form and fibers. We construct lasers in the UK using local high-quality supplies
for metalwork components and subassemblies. We procure standard
off-the-shelf-electronic components primarily from various UK and US suppliers.
Because of their complexity, high quality requirements and relatively low
volumes, we choose to procure our optical components from only two sources.

Semiconductor laser diodes are used in optical disc drives, optical fiber
telecommunications, printers and bar code scanners. No larger than a grain of
salt, the diode chip converts electricity into laser light with such efficiency
that power consumption and heat generation are reduced. Laser diodes are related
to the LEDs used as indicator lights in most electrical devices. While LEDs
produce light measured in milliwatts, high power laser diodes each produce
several watts of laser light. Because laser diodes are semiconductor components,
the products they support have no moving parts, are highly reliable and can be
run from a wall socket power supply with only limited requirements to cool the
components. The outcome of this miniaturization of laser technology is a
portable, lightweight, highly reliable and easy to use laser. Like electronic
semiconductors, management believes that semiconductor lasers will increasingly
replace most other laser technologies.

To achieve power levels beyond that of a single laser diode, light may be
coupled from multiple diodes. This may be achieved by attaching an optical fiber
to the end of each diode and "bundling" the fibers together. This entails a
number of optical fiber joints inside the laser system to guide and couple the
light. Each optical joint reduces the amount of light that passes through the
system and each joint also has a finite lifetime that is usually less than the
life of the diode. As one optical joint fails, the others come under greater
stress and are subject to an increased likelihood of cascade failure. The result
is an inefficient optical transfer where power delivered through the working end
of the fiber is only a small percentage of the power delivered by the diode.

                                       29


The most widely used medical diode laser emits laser energy at 810nm, producing
light in the near infra-red portion of the spectrum. At powers of up to 60W and
used in conjunction with a flexible optical delivery fiber, this wavelength can
be used in various surgical applications to cut, close or vaporize soft tissue.
Semiconductor diode chips at 630nm, 635nm, 652nm, 690nm and 730nm wave lengths
are also available, permitting an even wider array of medical applications.

We also use a number of different laser diodes for our various products. Diodes
for certain of our lasers are also currently single-sourced, although we are
exploring available opportunities for dual sourcing. Currently, the majority of
these suppliers are located in the U.S., Japan and Europe. In addition, we
purchase the fibers contained in our clinical solution kits, and those fibers
required to support our FibersDirect.com business, from suppliers in the U.S.
Because most of our raw materials and components are available from various
sources, we are currently developing qualified backup suppliers for each of
these resources.

We currently outsource most of our manufacturing of disposable fibers used in
EVLT(R), and other surgical procedures. We own the patent applications for
certain EVLT(R) disposable fiber technology and subcontract the manufacturing to
a third party. We subcontract the production of EVLT(R) kits of disposable
items, consisting principally of a fiber, a sheath used to introduce the fiber
into a vein, a guide wire, and a needle used to insert the sheath. Each of these
EVLT(R) components is currently purchased from third parties. We purchase
disposable fibers used in other surgical procedures directly from third parties.

We are required to manufacture our products to comply with the international
standard BS EN ISO 13485:2003 and the FDA's Quality System Regulations, or
"QSR." The ISO 13485 and QSR standards detail the methods and documentation of
the design, testing, control, labeling, packaging, storage and shipping of our
products. Our manufacturing facility is subject to periodic audits by regulators
who conduct inspections that must be satisfactory for us to maintain ISO
approval, and it is also auditable by the FDA. Our failure to maintain
compliance with the ISO 13485 and QSR requirements could result in the closure
of our manufacturing operations and the recall of our products. If one of our
suppliers were not to maintain compliance with our quality requirements, we
might have to qualify a new supplier and could experience manufacturing delays
as a result. In November 1999, we became certified to manufacture in the United
Kingdom and upgraded to BS EN ISO 13485: 2001. In 2002, we underwent an FDA
Quality Systems Regulation Inspection and received a satisfactory letter in from
the FDA as a result of this inspection. In 2004, we successfully completed an
external audit which allowed us to upgrade to BS EN ISO 13485:2003

                               SALES AND MARKETING

In the U.S., we sell, market and distribute our products and services through a
direct sales force. Our primary sales focus in the U.S. has been the
commercialization of EVLT(R). We initially used independent sales
representatives, switching to a direct sales force during the second half of
2002 to better manage the dynamics of selling clinical applications, including
lasers and disposable products. We currently employ 19 EVLT(R) sales
representatives, two regional sales managers and four clinical specialists,
including one training manager, in support of our field sales efforts. We plan
to fill one open sales territory. We hired two sales development personnel to
focus on VeinViewer(TM) sales and plan to hire one more. We will continue to
monitor sales activities and strategies and adjust the number of direct sales
representatives, independent sales representatives and distributors to address
market needs and opportunities in the future.

Internationally, we sell, market and distribute our products and services
through a combination of direct sales representatives and a global network of
distributors. We typically commit our distributors to minimum product purchases,
and we may terminate our relationships with distributors who do not meet those
minimum purchase levels. We have not given our distributors price protection or
product return rights. We do not remotely monitor inventory levels of our
products once we sell them to distributors, but may obtain that information as
needed by our contact with the distributor. We also develop and maintain
strategic marketing alliances for international sales and marketing. These
alliances exist under agreements with companies such as Olympus Medical Systems
Corporation. Each of these agreements relates to certain products and market
segments.

We target our marketing efforts to physicians through office visits, trade shows
and trade journals, and to consumers through point of service information
brochures and our websites, www.evlt.com (which provides information to patients
and physicians about EVLT(R)) and www.fibersdirect.com (which provides product
and pricing information to prospective customers about our available optical
fibers). Our sales philosophy includes establishing strong collaborations with
well-known professionals in the industry regarding our technology platforms,
compiling substantive clinical data and supporting the publication of peer
review articles. With respect to EVLT(R), we believe that we have collected more
clinical data regarding our products and their application than any of our
competitors in the endovenous laser treatment market.

In November 2000, we formed FibersDirect.com, a U.S. business unit that acts as
a direct marketing conduit by providing on-line information for available
products and access to our sales staff by e-mail. FibersDirect.com enables
distribution of fibers directly from the manufacturer to the end-user. Our
OPTIGUIDE(R) fibers, used in photodynamic therapy cancer treatments, are
promoted via FibersDirect.com.

                                       30


In 2003, no customer accounted for more than 10% of our revenues, and U.S. sales
represented 63% of total revenue. In 2004, no customer accounted for more than
10% of our revenues and approximately 66% of our sales were generated in the
U.S. In 2005, no customer accounted for more than 10% of our revenues and
approximately 75% of our sales were generated in the U.S. Going forward, we
believe that our annual dependence on any individual customer or group of
customers should decrease because we expect more of our revenues to be generated
from sales of EVLT(R) to individual physician practices and hospitals rather
than to large-scale distributors. In addition, we believe that our percentage of
sales generated domestically should increase as EVLT(R) market penetration in
the U.S. increases.

For the remainder of 2005 and in 2006, we plan to continue to focus on the
development and growth of EVLT(R) sales worldwide. We will continue to support
the development and approval of new applications for other products, and to
continue our research and development efforts aimed at enhancing our products'
effectiveness and manufacturing efficiencies.

                                   COMPETITION

The medical device industry is highly competitive and regulated and is subject
to rapid and substantial technological change. We compete primarily on the basis
of performance, brand name, reputation and price. Developments by others, both
public and private, may render our products noncompetitive or obsolete, or we
may be unable to keep pace with technological developments and other market
factors. Existing and potential competitors may develop products and clinical
solutions that could prove to be more effective, safer or less costly than our
products and clinical solutions. Many of these competitors have significantly
greater financial and human resources than we do, and have established
reputations as well as worldwide distribution channels that are more effective
than ours. Such competition involves an intensive search for technological
innovations and the ability to market these innovations effectively. The
introduction of new products and clinical applications by competitors may result
in price reductions, reduced margins, loss of market share and product
replacements, even for products protected by patents. There can be no assurance
that competitors, many of which may have made substantial investments in
competing technologies, would not prevent, limit or interfere with our ability
to make, use or sell our products either in the United States or in
international markets. To compete effectively in the marketplace, we require the
financial resources to effectively support our activities in research and
development, regulatory compliance, quality control, sales and marketing,
distribution and technical information and training services.

In the vein treatment market, our competitors include manufacturers and
marketers of surgical and radiofrequency devices, and pharmaceutical companies
that provide drugs used in sclerotherapy and other vascular diseases. Within the
specific endovenous laser treatment market which our EVLT(R) products serve,
Biolitec A.G., AngioDynamics, Inc., Vascular Solutions, Inc., New Star Lasers,
Inc., d/b/a CoolTouch, Inc. and Dornier MedTech GmbH are our main competitors
for surgical diode lasers. AngioDynamics does not manufacture lasers or optical
fiber, and we understand it currently has an original equipment manufacturing
agreement with Biolitec for these goods. AngioDynamics received FDA clearance
for its device in November 2002, approximately 10 months after Diomed, while
CoolTouch recently received FDA clearance for its laser treatment of varicose
veins on September 30, 2004. Biolitec, Lumenis and Dornier, among others, are
our competitors in the general surgical laser market. AngioDynamics, Total Vein
Solutions, Inc. and Vascular Solutions, Inc. currently compete with us for sales
of kits used in endovenous laser treatment.

We believe that our EVLT(R) system and comprehensive physician management tools
are superior to the products offered by our direct competitors. EVLT(R) uses a
laser wavelength that has been proven effective in FDA trials and in peer
reviewed data. Compared to varicose vein treatments using radiofrequency as
offered by our competitor, VNUS Technologies, Inc., Diomed's EVLT(R) treatment
is a faster procedure, uses substantially less expensive disposables, has
clinically proven results that are superior to the results reported for VNUS and
does not have any of the serious complications reported by VNUS. EVLT(R) offers
physicians comprehensive practice management tools, including physician training
and practice development. Dornier, Biolitec and AngioDynamics offer some
practice management assistance, but we believe that, to the extent offered, our
competitors' practice management tools are significantly less comprehensive than
ours.

In the cancer treatment market, our competitors include manufacturers and
marketers of surgical and radiation therapy devices, and all the pharmaceutical
companies that provide various drugs used in chemotherapy and immunotherapy.
Within the specific photodynamic therapy market, Lumenis, Laserscope and
Biolitec are our main competitors. We currently have one FDA-cleared diode laser
in the U.S. for photodynamic therapy cancer applications, which is used in
conjunction with Axcan Pharma's Photofrin(R) drug for late stage lung and
esophagus cancers.

We also face competition from current widespread treatment practices, including
surgery, chemotherapy and radiation. Since most photodynamic therapy cancer
treatments are still in clinical trials, no long-term safety or efficacy data is
available. As a result, cancer patients may be more likely to choose proven
traditional forms of treatment.

We expect that our principal methods of competition with other photodynamic
therapy support companies will be based upon such factors as:

      - the ease of administration of our partners' photodynamic therapy
methodologies;

      - the degree of generalized skin sensitivity to light;

      - the number of required doses;

                                       31


      - the safety and efficacy profile;

      - the selectivity of photodynamic therapy drug for the target lesion or
        tissue of interest;

      - the type and cost of our light systems; and

      - the cost of our partners' drug.

Increased competition could result in:

      - price reductions;

      - lower levels of third-party reimbursements;

      - failure to achieve market acceptance for our photodynamic therapy
        product line, and loss of market share.

                 PATENTS, TRADEMARKS AND PROPRIETARY TECHNOLOGY

We hold U.S. and international patents for inventions endovenous laser treatment
of varicose veins, solid state laser diode light source, high power light
source, peltier-cooled and medical spacing guide. These patents expire from 2011
to 2019.

In June 2002, the U.S. Patent and Trademark Office issued Patent No. 6,398,777
("Endovascular laser device and the treatment of varicose veins"). We formerly
licensed technology for the EVLT(R) process from one of its inventors, Dr.
Robert Min, on a non-exclusive basis, although Dr. Min had agreed not to license
the process technology to any third party so long as we complied with our
obligations under the agreement. On September 3, 2003, Diomed acquired exclusive
rights to U.S. Patent No. 6,398,777 and related foreign patents for endovenous
laser treatment of varicose veins, in two transactions.

In the first transaction, Diomed purchased the interest in the EVLT(R) patent
owned by one of its five named inventors, Dr. Robert J. Min. This transaction
was completed under a purchase agreement between Diomed and Dr. Min entered into
on July 23, 2003. On September 3, 2003, Diomed paid the purchase price set forth
in the Purchase Agreement (consisting of $500,000 in cash and options to
purchase 40,000 (as adjusted by the 1:25 reverse split, effective June 17, 2004)
shares of our common stock) in exchange for Dr. Min's assignment to Diomed of
his interest in the EVLT(R) patent. Diomed has agreed to pay to Dr. Min variable
payments based on Diomed's sales of products using the EVLT(R) patent. Dr. Min
had previously licensed the EVLT(R) patent to Diomed and had served as a
consultant to Diomed. Dr. Min's consulting agreement with Diomed was amended to
reflect the changes in the relationship between him and Diomed as a result of
Diomed's acquisition of the EVLT(R) patent rights. Dr. Min is expected to
continue to act as a consultant to Diomed under the revised consulting
agreement.

In the second transaction, Diomed licensed, on an exclusive basis, the EVLT(R)
patent from Endolaser Associates, LLC, the assignee of interest in the EVLT(R)
patent from the other four named inventors. This transaction was completed under
a license agreement between Diomed and Endolaser Associates entered into on July
11, 2003. On September 3, 2003, Diomed paid Endolaser Associates $1.5 million in
cash in exchange for the exclusive license granted by Endolaser Associates on
behalf of the four inventors who had assigned their interest in the EVLT(R)
patent to Endolaser Associates. Diomed is to make additional payments totaling
$2.5 million in 10 quarterly installments of $250,000 each, commencing October
1, 2003. Diomed paid all such payments due through October 1, 2005. Diomed has
agreed to pay ongoing variable royalties based on Diomed's sales of products
subject to the EVLT(R) patent.

Together with Dr. Min and his associate, Dr. Stephen Zimmet, we also invented
fiber technology that we use with our EVLT(R) products. Drs. Min and Zimmet
assigned to us their rights to a patent application regarding this technology.
As of September 30, 2005, this patent application was still pending before the
U.S. Patent and Trademark Office. We pay a fee for our sale of fibers
incorporating this technology. Doctors Min and Zimmet also provide services to
us on an ongoing basis to educate physicians on the use of our EVLT(R) products,
and we pay them fees for these services.

We license technology that we currently use in our OPTIGUIDE(R) fiber optic
diffuser. Health Research, Inc. owns this patented technology, and exclusively
licenses it to QLT, Inc. In turn, QLT sublicenses it to us on a non-exclusive
basis. The sublicense continues until the licensed patent rights expire or the
license from Health Research to QLT is terminated, whichever comes first. Health
Research may terminate its license to QLT if QLT breaches its obligations under
the license and does not cure the breach within 90 days, or if QLT becomes
insolvent. QLT may terminate our sublicense if we breach our obligations under
the sublicense, such as failing to pay royalties, and do not cure the breach
within 90 days, or if we become insolvent.

We have received trademark registrations from the U.S. Patent and Trademark
Office for the trademarks "Diomed," "OPTIGUIDE" and "EVLT." We have initiated
trademark registrations "Summer Legs" as a trademark and/or service mark, but we
have not yet received registrations for this particular mark. We registered
various domain names, including diomedinc.com, diomed-lasers.com,
fibersdirect.com, fibresdirect.com, summerlegs.com and evlt.com.

                                       32


Our proprietary technology includes:

      - a device for scanning laser beams in a pre-defined pattern across the
        patient's skin;

      - an enclosure for protecting laser diodes and modules;

      - a low cost method for measuring the light from optical fibers of
        differing geometry (under development);

      - a common platform for laser diodes of different wavelengths;

      - a user interface that is appropriate to the clinical setting;

      - a monolithic optical geometry for implementing the patented technology;

      - a means for driving the laser diodes that provides a wide dynamic range;
        and

      - a means for efficiently removing heat from the diodes thereby allowing
        the instrument to operate with standard line power as the only service.

The patent position of medical device companies generally is highly uncertain.
Some of the risks and uncertainties include:

      - the patent applications owned by or licensed to us may not result in
        issued patents;

      - our issued patents may not provide us with proprietary protection or
        competitive advantages;

      - our issued patents may be infringed upon or designed around by others;

      - our issued patents may be challenged by others and held to be invalid or
        unenforceable;

      - the patents of others may have a material adverse effect on us; and

      - significant time and funds may be necessary to defend our patents.

We are aware that our competitors and others have been issued patents relating
to optical fibers and laser devices. In addition, our competitors and others may
have been issued patents or filed patent applications relating to other
potentially competitive products of which we are not aware. Further, in the
future our competitors and others may file applications for patents, or
otherwise obtain proprietary rights to technology that can be used for such
products. These existing or future patents, applications or rights may conflict
with our patents or applications. These conflicts could result in a rejection of
our or our licensors' patent applications or the invalidation of issued patents,
any of which could have a material adverse effect on our ability to focus on the
development or marketing of these applications. If conflicts occur, or if we
believe that other products may infringe on our proprietary rights, we may
pursue litigation or other legal remedies, or may be required to defend against
litigation. Indeed, we have sued several competitors to assert our intellectual
property rights, and we have been sued by a competitor who has alleged that we
infringed its intellectual property rights. Legal proceedings may materially
adversely affect our competitive position, and we may not be successful in any
such proceeding. Litigation and other proceedings can be expensive and time
consuming, regardless of whether we prevail. This can result in the diversion of
substantial financial, managerial and other resources from other activities. An
adverse outcome could subject us to significant liabilities to third parties or
require us to cease any related research and development activities or product
sales.

We also seek to protect our proprietary technology and processes in part by
confidentiality agreements with our collaborative partners, employees and
consultants. These third parties may breach their agreements with us, and we may
not have adequate remedies for their breach. Also, competitors may independently
learn or discover our trade secrets.

intellectual property, see "Risk Factors," above, and for a discussion of
current litigation involving our intellectual property, see "Legal Proceedings,"
below.

                              GOVERNMENT APPROVALS

The FDA and comparable international regulatory bodies regulate our medical
device products and their applications.

In the United States, our products are regulated as medical devices by the FDA
under the Federal Food, Drug, and Cosmetic Act, or FDC Act, and require
clearance of a premarket notification under Section 510(k) of the FDC Act or
approval of a PMA application, under Section 515 of the FDC Act prior to
commercialization. Pursuant to the FDC Act, the FDA regulates, among other
things, the following aspects of medical devices: product design and
development, product testing for safety and efficacy,. product manufacturing,
product labeling, product storage, pre-market clearance or approval, product
sales and distribution, record keeping, reporting of adverse events and
corrective actions, recalls and removals.

In addition, in conjunction with the Federal Trade Commission, the FDA regulates
the advertising and promotion of the medical devices in the United States.
Failure to comply with the applicable requirements can result in sanctions such
as warning letters, fines, injunctions, civil and criminal penalties against us,
our officers, and our employees, recall or seizure of products, total or partial
suspension of production, refusal of the government to grant premarket clearance
or premarket approval for devices, withdrawal of marketing approvals and
recommendation that we may not be permitted to enter into government contracts.

                                       33


Unless an exemption applies, each medical device we wish to commercially
distribute in the U.S. will require either prior clearance by the FDA on the
basis of what is called a "510(k) application," or a pre-market approval ("PMA")
application. The FDA classifies medical devices that are manufactured or sold in
the U.S. into one of three classes. Devices deemed to pose lower risks are
placed in either class I or II, which requires the manufacturer to submit to the
FDA a pre-market notification requesting permission to commercially distribute
the device. This process is generally known as 510(k) pre-market notification.
Devices deemed by the FDA to pose the greatest risk, such as life-sustaining,
life-supporting or implantable devices, or devices deemed not substantially
equivalent to a previously cleared 510(k) device, are placed in class III,
requiring pre-market approval upon a PMA application submitted by the applicant.

Our laser devices require either 510(k) or pre-market application approval,
depending on the clinical application sought. Our devices generally qualify for
clearance under 510(k) procedures. To obtain 510(k) clearance, we must submit a
pre-market notification demonstrating that our proposed device is substantially
equivalent to a previously cleared 510(k) device or a device that was in
commercial distribution before May 28, 1976 (the date that the FDA called for
the submission of PMA applications). The FDA's 510(k) clearance review has
recently taken from three to twelve months from the date the application is
submitted, but it can take significantly longer.

After a device receives 510(k) clearance, any material changes, major design
changes, changes to the safety and efficacy of the product, new claims or
indications for use and new technology with no prior history of use in medical
devices are subject to a new 510(k) clearance requiring a rigorous demonstration
of substantial equivalence to a currently marketed device and or clinical
trials. Any modification that could significantly affect its safety or
effectiveness, or that would constitute a major change in its intended use,
requires a new 510(k) clearance or, alternatively, could require pre-market
approval. The FDA requires each manufacturer to make this determination
initially, but the FDA can review any such decision and can disagree with a
manufacturer's determination. If the FDA disagrees with a manufacturer's
determination, the FDA can require the manufacturer to cease marketing and/or
recall the modified device until 510(k) clearance or obtain pre-market approval.
If the FDA requires us to seek 510(k) clearance or pre-market approval for any
modifications to a previously cleared product, we may be required to cease
marketing or recall the modified device for the unapproved, or so called
"offlabel," use until we obtain this clearance or approval. Also, under these
circumstances, we may be subject to significant regulatory fines or penalties.
We expect that any additional applications that we may seek for our existing
laser products will require pre-market approval. The FDA requires pre-market
approval for each specific clinical procedure.

We are the first company to receive FDA clearance for use of lasers and related
applications in endovenous laser treatment and first diode laser manufacturer to
receive FDA clearance for use of lasers in photodynamic therapy cancer
treatments. In January 2002, we received FDA clearance for use of endovenous
laser treatment in the U.S., in respect of our EVLT(R) product line, making us
the first company to receive FDA clearance for this modality and use.
Specifically, the FDA approved our EVLT(R) surgical laser and procedure kit as
intended for use in ablation of the greater saphenous vein of the thigh in
patients with varicose veins, and the FDA specifically found that the FDA would
not require us to submit a pre-market approval application for this use. In
December 2002, the FDA granted clearance for the use of EVLT(R) for expanded
indications, namely, the use of our D15plus and D30plus diode lasers and
disposable kits for the treatment of varicose veins and varicosities associated
with the superficial vein reflux of the greater saphenous vein. In December
2004, we obtained FDA clearance authorizing the use of our laser and procedure
kits for treatment of venous incompetence and reflux of other superficial veins
in the lower extremity.

In August 2000, we and Axcan Pharma received regulatory approval for our 630nm
laser and OPTIGUIDE(R) fiber, and Axcan Pharma's Photofrin(R) drug used in the
cancer treatment for late stage lung and esophageal cancers. In August 2003,
Axcan Pharma announced that it received FDA clearance in connection with an
application it had made for expanded indications of the use of Photofrin(R) in
conjunction with our photodynamic therapy laser products for the treatment of
Barrett's Esophagus. In September 2004, our laser development and supply
agreement with Axcan Pharma, dated August 2, 2000, was terminated and as a
result, we are no longer distributing PDT lasers through Axcan Pharma. Sales to
Axcan Pharma represented approximately 1% or less of our sales in 2003 and 2004.
We will continue to market PDT lasers through our direct sales force and
distributors, both domestically and internationally.

We are also regulated under the Radiation Control for Health and Safety Act,
which requires laser products to comply with performance standards, including
design and operation requirements, and manufacturers to certify in product
labeling and in reports to the FDA that their products comply with all such
standards. The law also requires laser manufacturers to file new product reports
and annual reports, maintain manufacturing, testing and sales records, and
report product defects. We must affix various warning labels and install certain
protective devices, depending on the class of the product.

Our failure to comply would initially result in a warning letter from FDA
informing us of the noncompliance. Action to correct the non-compliance range
from a field correction, such as new labeling being sent to existing customers
by mail, to a formal recall of the labeling and replacement with compliant
material. As compliance with existing regulations is included in our new product
development protocol, it is unlikely a non-compliance will occur. Labeling and
new product compliance are reviewed at discrete intervals during new product
development by regulatory and compliance departments prior to the release of any
new products.

                                       34


International sales of our products are subject to strict regulatory
requirements, which vary substantially from country to country. Our key
international markets are the European Union, Japan, Australia, South Korea,
Peoples Republic of China and Canada. The time required to obtain clearance or
approval by a foreign country may be longer or shorter than that required for
FDA clearance or approval, and the requirements may be different.

The European Union, which consists of fifteen countries encompassing most of the
major countries in Europe, has adopted numerous directives and standards
regulating the design, manufacture, clinical trials, labeling and adverse event
reporting for medical devices. Devices that comply with the requirements of a
relevant directive may bear the CE conformity marking indicating that the device
conforms with the essential requirements of the applicable directives and,
accordingly, may be commercially distributed throughout Europe. ISO 9001
certification is one of the CE Mark certification requirements. In November
1999, our facility was awarded ISO 9001 and EN 46001 certification, thereby
allowing us to apply the CE mark to our products and market them throughout the
European Union. In September 2001, we were the first company to receive the CE
mark of approval for marketing endovenous laser therapy products in Europe.

Outside of the European Union, we must obtain country-by-country approval to
import our products. Certain countries, such as Switzerland, have voluntarily
adopted laws and regulations that mirror those of the European Union with
respect to medical devices.

                            THIRD-PARTY REIMBURSEMENT

A patient's ability to secure reimbursement for our existing and future products
is critical to our success. In the U.S., health care providers generally rely on
third-party payors, principally private health insurance plans and Medicare and
Medicaid, to reimburse all or part of the cost of procedures in which medical
devices are used. However, we cannot assure that EVLT(R) and photodynamic
therapy, and future products that we develop in connection with photodynamic
therapy, endovenous or other medical and clinical procedures, will be
reimbursed, or that the amounts reimbursed to physicians would be adequate.

The current cost reduction orientation of the third-party payor community makes
it exceedingly difficult for new medical devices and surgical procedures to
obtain reimbursement. Often, it is necessary to convince payors that the new
devices or procedures will establish an overall cost savings compared to
currently reimbursed devices and procedures. We believe that EVLT(R) may offer
an opportunity for payors to reduce the costs of treating varicose vein patients
by possibly reducing significantly the number of vein stripping procedures
performed. We estimate that the cost of varicose vein treatment using EVLT(R) is
approximately 25% of the cost of vein stripping procedures. While we believe
that EVLT(R) possesses economic advantages that will be attractive to payors, we
cannot assure that they will make reimbursement decisions based upon these
advantages.

Reimbursement by third-party payors is often positively influenced by the
existence of peer-reviewed publications of safety and efficacy data and
recommendations by knowledgeable physicians. With regard to EVLT(R), we
currently exceed the competition in the magnitude of clinical data we have
compiled, and we are currently the only company to have peer-reviewed articles
published in scientific journals addressing endovenous laser treatment. A study,
entitled "Endovenous Laser Treatment of Saphenous Vein Reflux: Long-Term
Results," was published in the August 2003 issue of the Journal of Vascular and
Interventional Radiology. This study shows what we believe to be excellent
long-term results for the removal of varicose veins caused by reflux of the
greater saphenous vein. The study was co-authored by Dr. Robert Min, Director of
Cornell Vascular in New York and Vice-Chairman of Radiology at Weill Medical
College of Cornell University. Dr. Min is a consultant to Diomed, and is an
inventor of the EVLT(R), who sold his rights to this patented technology to
Diomed on September 3, 2003. Dr. Min assists Diomed in physician training and in
the development of medical treatments using EVLT(R). For further details of this
study, see "Products, Competencies and Market Opportunities--Endovenous Laser
Treatment."

Additionally, we believe that our significant investment in proactive
reimbursement activities has produced dramatic results in both the number and
breadth of insurance carriers willing to provide positive EVLT coverage. The
list of private, regional and national insurance providers with positive
coverage policies on EVLT(R) has grown significantly, driven in large part by
the addition of UnitedHealth Group Inc. UnitedHealthcare has joined other
organizations such as Aetna Inc., Cigna Health Care and Humana Inc. along with
an extensive list of independent Blue Cross Blue Shield and Medicare (Part B)
carriers now providing our growing EVLT(R) patient base with access to broad
insurance coverage.

On November 4, 2004, the Center for Medicare and Medicaid Services (CMS)
established reimbursement codes for laser ablation as a mode of treatment for
superficial vein disorders, including EVLT(R) for varicose veins. The new codes,
which are established by the American Medical Association and the CMS, form the
basis for Medicare and Medicaid reimbursement across the U.S. and became
effective January 1, 2005. Including Medicare/Medicaid reimbursements, as of
November 30, 2005, we list over 63 coverage policies representing over 217
million covered lives.

Under the new codes, doctors performing the EVLT(R) procedure in an office or
clinic setting are reimbursed an unadjusted base rate of $2,041 for the first
vein treated under code #36478; second and additional veins at a base rate of
$437 under code #36479. When performed in a hospital setting, the new codes
allow for professional (Part B) payments of $364 for the first vein treated and
$178 for the second and additional veins, along with applicable hospital
facility fees. These base rates are adjusted for regional cost differences.

                                       35


Reimbursement systems in international markets vary significantly by country
and, within some countries, by region. Reimbursement approvals must be obtained
on a country-by-country basis or a region-by-region basis. In addition,
reimbursement systems in international markets may include both private and
government-sponsored insurance. We cannot be certain that we will be able to
continue to obtain such approvals in a timely manner, if at all. If we fail to
receive acceptable levels of international reimbursement approvals, market
acceptance of our products in those countries is likely to be adversely
affected.

Nevertheless, the efforts of governments and third-party payors to contain or
reduce the cost of healthcare will continue to affect our business and financial
condition as a medical device company. In foreign markets, pricing or
profitability of medical products and services may be subject to government
control. In the U.S., we expect that there will continue to be federal and state
proposals for government control of pricing and profitability. In addition,
increasing emphasis on managed healthcare has increased pressure on pricing of
medical products and will continue to do so. These cost controls may have a
material adverse effect on our revenues and profitability, and may affect our
ability to raise additional capital.

In addition, cost control initiatives could adversely affect our business in a
number of ways, including:

      - decreasing the price we, or any of our partners or licensees, receive
        for any of our products;

      - preventing the recovery of development costs, which could be
        substantial; and

      - limiting profit margins.

                               NUMBER OF EMPLOYEES

As of December 1, 2005, we employed a total of 88 full-time employees, 43 of
whom are based in the U.S. and 45 of whom are based at Diomed Ltd., our
wholly-owned subsidiary in Cambridge, England, where manufacturing and certain
international sales are conducted. We believe that our future success will
depend in part on our continued ability to attract, hire and retain qualified
personnel. None of our employees is represented by a labor union. We believe our
employee relations are good.

                                LEGAL PROCEEDINGS

MISAPPROPRIATION LITIGATION VS. VASCULAR SOLUTIONS

On December 12, 2003, we filed a lawsuit in the United States District Court for
the District of Massachusetts seeking injunctive and other relief against
Vascular Solutions, Inc. and one of its executives. We allege, among other
things, that Vascular Solutions and the executive misappropriated our trade
secrets and then improperly used that information to develop and market laser
accessory products. We also seek to redress what we allege to be the willful and
deceptive manner in which Vascular Solutions has been marketing its laser
accessory products by, among other things:

      - infringing our registered EVLT(R) mark, including by Vascular Solutions'
        use of the mark "ELT;"

      - marketing Vascular Solutions' products in a way designed to confuse
        consumers as to the source and origin of its products;

      - making false and defamatory statements about us and our products;

      - tortiously interfering with our existing and prospective customer
        relationships; and

      - tortiously interfering with agreements previously entered into by the
        executive and us that prohibit the executive from disclosing our
        confidential information to Vascular Solutions or any other third
        party.

On June 16, 2004, Vascular Solutions and the other the defendant answered the
complaint, and filed a counterclaim for invalidity of the EVLT(R) trademark. On
July 13, 2005 the Court heard oral argument on Vascular Solutions' motion for
summary judgment on all claims. Vascular Solutions conceded that it would
stipulate to desist from any further use of the mark ELT, which Diomed alleged
infringes Diomed's federally-registered EVLT(R) trademark. Vascular Solutions
further stipulated that it would desist from any further dissemination of the
defamatory statements alleged in Diomed's complaint.

'777 PATENT LITIGATION

On March 4, 2004, we filed a second lawsuit against Vascular Solutions in the
United States District Court for the District of Massachusetts seeking
injunctive relief and damages for infringement of our U.S. Patent Number
6,398,777 (the "'777 patent") covering the endovascular laser treatment of
varicose veins which we use in our EVLT(R) product line, the exclusive rights to
which we acquired on September 3, 2003.

                                       36


On April 28, 2004, Vascular Solutions answered the complaint and filed a
counterclaim for declaratory judgment that the '777 patent is invalid and not
infringed. Vascular Solutions amended its answer and counterclaims to further
allege patent unenforceability. In addition, Vascular Solutions moved to
bifurcate the damages and willful infringement aspects of this case. We opposed
this motion and on June 28, 2005 the court denied Vascular Solutions' motion.

We are now completing the discovery phase of this litigation. For purposes of
efficiency, this case has been consolidated with another case for pretrial
purposes as discussed below.

On January 6, 2004, we filed a lawsuit in the United States District Court for
the District of Massachusetts against AngioDynamics, Inc. seeking injunctive
relief and damages for infringement of the '777 patent. AngioDynamics has
generally denied our allegations and has sought a declaratory judgment of
invalidity of the '777 patent. AngioDynamics has also added certain
counterclaims against us, including antitrust violations, patent misuse and
other allegations, all arising from our obtaining and seeking to enforce the
'777 patent. The court has bifurcated the case, so that those counterclaims will
not be litigated until we resolve our patent infringement claims against
AngioDynamics. At the parties' joint request, however, our patent cases
involving AngioDynamics and Vascular Solutions have been consolidated by the
court for pretrial purposes. We are now completing the discovery phase of this
litigation.

On April 12, 2005, the Court issued a claim construction ruling, which
interprets certain claim language in the '777 patent. We believe that the
evidence we have developed to date in the course of these lawsuits if admitted
and fully credited will show that AngioDynamics and Vascular Solutions are
infringing our patent as it has now been interpreted by the Court.

On April 2, 2004, we filed a lawsuit in the United States District Court for the
District of Massachusetts against Total Vein Solutions, LLC, seeking injunctive
relief and damages for infringement of the '777 patent covering the endovascular
laser treatment of varicose veins which we use in our EVLT(R) product line. On
May 21, 2004, Total Vein Solutions answered the complaint, generally denying our
allegations and counterclaiming for declaratory judgment of non-infringement and
invalidity of the EVLT(R) patent. We are in the discovery phase of this
litigation.

On October 14, 2004, we filed a lawsuit in the United States Federal District
Court for the District of Massachusetts against New Star Lasers, Inc., d/b/a
Cooltouch, Inc., seeking injunctive relief and damages for infringement of the
'777 patent covering the endovascular laser treatment of varicose veins which we
use in our EVLT(R) product line. On December 3, 2004, CoolTouch answered the
complaint, generally denying our allegations and counterclaiming for declaratory
judgment of non-infringement and invalidity of the EVLT(R) patent. We are now
proceeding with the discovery phase of this litigation.

VNUS TECHNOLOGIES LITIGATION

On July 21, 2005, a lawsuit was filed against us in the United States District
Court for the Northern District of California by VNUS Medical Technologies,
Inc., alleging infringement of U.S. patents Nos. 6,258,084, 6,638,273,
6,752,803, and 6,769,433. The complaint was served on us on July 27, 2005. On
September 15, 2005, we filed an answer denying the allegations of infringement,
and counterclaiming against VNUS for a declaration that none of the patents are
infringed and that they are all invalid. On October 12, 2005, VNUS served an
amended complaint adding two additional parties, AngioDynamics, Inc. and
Vascular Solutions, Inc., as defendants. On October 31, 2005, we filed an answer
to the First Amended Complaint, again denying the allegations of infringement,
and counterclaiming against VNUS for a declaration that none of the patents are
infringed, that they are all invalid and that two of VNUS' patents are
unenforceable for inequitable conduct. An initial scheduling conference for the
case has been set for December 2, 2005. We intend to continue defending this
case.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                  OF FINANCIAL CONDITION OR PLAN OF OPERATION



You should read the following discussion of our financial condition and results
of operations together with the audited consolidated financial statements and
notes to the financial statements at December 31, 2004 and the unaudited
financial statements and notes thereto, all of which are included elsewhere in
this prospectus.

This section contains forward-looking statements which involve known and unknown
risks and uncertainties. These statements relate to our future plans,
objectives, expectations and intentions. These statements may be identified by
the use of words such as "may," "will," "should," "potential," "expects,"
"anticipates," "intends," "plans," "believes" and similar expressions. These
statements are based on our current beliefs, expectations and assumptions and
are subject to a number of risks and uncertainties. Our actual results could
differ materially from those discussed in these statements. We refer you to the
"Risk Factors" on pages 6 through 18 of this prospectus for a discussion of
certain risks, including those relating to our business as a medical device
company without a significant operating record and with operating losses, our
risks relating to the commercialization of our current and future products and
applications, and risks relating to our common stock and its market value.

In view of our relatively limited operating history, we have limited experience
forecasting our revenues and operating costs. Therefore, we believe that
period-to-period comparisons of financial results are not necessarily meaningful
and should not be relied upon as an indication of future performance. To date,
the Company has incurred substantial costs to create or acquire our products. As
of June 30, 2005, we had an accumulated deficit of approximately $76 million,
including $17.4 million in non-cash interest expense. We may continue to incur
operating losses due to spending on research and development programs, clinical
trials, regulatory activities, and sales, marketing and administrative
activities. This spending may not correspond with any meaningful increases in
revenues in the near term, if at all. As such, these costs may result in losses
until such time as the Company generates sufficient revenue to offset such
costs.

The following discussion should be read in conjunction with the financial
statements and the notes thereto included in this prospectus.

                                    OVERVIEW

We develop and commercialize minimally invasive medical procedures that employ
our laser technologies and associated disposable products. Using our proprietary
technology, including our exclusive rights to U.S. Patent No. 6,398,777, we
currently focus on endovenous laser treatment (EVLT(R)) of varicose veins. We
also develop and market lasers and disposable products for photodynamic therapy
(PDT) cancer procedures and products for other clinical applications, including
dental and general surgical procedures.

In developing and marketing our clinical solutions, we use proprietary
technology and aim to secure strong commercial advantages over competitors by
obtaining exclusive commercial arrangements, gaining governmental approvals in
advance of others and developing and offering innovative practice enhancement
programs, including physician training and promotional materials. To optimize
revenues, we focus on clinical procedures that generate revenues from both
capital equipment and disposable products, such as procedure kits and optical
fibers.

Our high power semiconductor diode lasers combine clinical efficacy, operational
efficiency and cost effectiveness in a versatile, compact, lightweight,
easy-to-use and easy-to-maintain system. Along with lasers and single-use
procedure kits for EVLT(R), we provide our customers with state-of-the-art
physician training and practice development support.

In 2001, we pioneered the commercialization of endovenous laser treatment
(EVLT(R)), an innovative minimally invasive laser procedure for the treatment of
varicose veins caused by greater saphenous vein reflux. In September 2001, we
were the first company to receive the CE mark of the European Economic Union for
approval for endovenous laser treatment with respect to marketing EVLT(R) in
Europe. In January 2002, we were the first company to receive FDA clearance for
endovenous laser treatment of the greater saphenous vein. In December 2004, we
received FDA clearance to expand the application of EVLT(R) to other superficial
veins in the lower extremities.

EVLT(R) was a primary source of revenue in 2004, and will continue to be our
primary source of revenue in 2005. We believe that EVLT(R) will achieve a high
level of commercial acceptance due to its relative short recovery period,
immediate return to the patient's normal routine barring vigorous physical
activities, reduced pain and minimal scarring, and reduced costs compared to
other treatments for varicose veins. We developed our EVLT(R) product line as a
complete clinical solution and marketing model, including a laser, disposable
kit, clinical training and customized marketing programs, to assist office-based
and hospital-based physicians in responding to the growing demand for treatment
of varicose veins in a minimally invasive manner. We have also published a
health insurance reimbursement guide to assist physicians in the reimbursement
submission process. We believe that these attributes, in addition to EVLT(R)'s
superior clinical trial results, favorable peer reviews, and comparatively
larger and longer follow-up data reports provide EVLT(R) with a competitive
advantage over competing traditional and minimally invasive varicose vein
treatment products.


                                       38



We expect that as the number of EVLT(R) procedures increases, so will our sales
of associated disposable items. We believe that the U.S. represents the single
largest market for EVLT(R). We target our sales and marketing efforts at
hospitals, private physician practices and clinics and focus on specialists in
vascular surgery, interventional-radiology, general surgery, phlebology,
interventional cardiology, gynecology and dermatology.

We primarily utilize a direct sales force to market our products in the United
States and a network of more than 30 distributors to market our products abroad.
In August 2005, we entered into a three year agreement with Luminetx, Inc. to
acquire exclusive distribution rights to the VeinViewer(TM) Imaging System for
the sclerotherapy, phlebectomy and varicose vein treatment markets in the United
States and United Kingdom. In June 2005, we entered into an exclusive
distribution agreement with Colorado-based Med1 Online, Inc., a leading online
distributor of capital medical equipment in the United States. Under the terms
of the three-year renewable distribution agreement, Med1Online acquired
exclusive distribution rights to market our EVLT(R) product line to the OB/GYN
and plastic surgery physician market segments in the United States. We currently
employ 19 EVLT(R) sales representatives, two regional sales managers and a vice
president of North American sales. We plan to fill one open sales territory. We
hired two sales development personnel to focus on VeinViewer(TM) sales and plan
to hire one more. Additionally, our current clinical support organization
employs four clinical specialists, including one training manager, who support
our field sales efforts. These clinical specialists assist in physician training
and post-sales support, freeing our sales representatives to focus on new sales
opportunities.

We have developed and maintain a website - www.EVLT.com - to assist both
patients and physicians. EVLT.com provides patients with education about
treatment options and benefits of EVLT(R) and provides physicians with education
about the EVLT(R) procedure. At www.EVLT.com, patients can also locate the
nearest physician performing EVLT(R) by inputting their city and state. We also
maintain a corporate website - www.diomedinc.com - which includes information
about the Company and our physician support initiatives, among other things.

Although we have continued to focus on the development and growth of EVLT(R)
sales both domestically and internationally, we will continue to support the
development and approval of new applications for PDT products and the
development of enhancements to our products in order to further improve their
quality, effectiveness and manufacturability. Our management team focuses on
developing and marketing solutions that address serious medical problems that
have significant markets. Our determinations are based upon the number of
procedures that may be conducted in a market and projections of the associated
revenue. Currently, EVLT(R) applications fall within this guideline, and we
believe that photodynamic therapy may have the potential to do so at some time
in the future. However, EVLT(R), and not PDT, is the emphasis of our current
business plan.

                              RESULTS OF OPERATIONS


              THREE MONTHS ENDED SEPTEMBER 30, 2005 COMPARED TO THE
                      THREE MONTHS ENDED SEPTEMBER 30, 2004

REVENUE

Diomed delivered revenue for the three months ended September 30, 2005 of
$4,583,000, increasing approximately $1,306,000, or 40%, from $3,276,000 for the
three months ended September 30, 2004. Revenue from the EVLT(R) product line
increased 56% over the three months ended September 30, 2004, including North
America EVLT(R) growth of 82%, demonstrating the continued and growing
acceptance of EVLT(R) by the medical community and patients alike.

For the three months ended September 30, 2005, approximately $2,194,000, or 48%,
of our total revenue was derived from laser sales, as compared to approximately
$1,878,000, or 57%, in the three months ended September 30, 2004. In the three
months ended September 30, 2005, approximately $2,389,000, or 52%, of our total
revenues were derived from sales of disposable fibers and kits, accessories and
service, as compared to approximately $1,398,000, or 43%, in the same period in
2004. We expect the proportion of revenue derived from disposables to increase
as we establish a larger base of installed lasers and the number of EVLT(R)
procedures performed grows.

The increase in revenue is attributable primarily to:

      -     increased penetration of EVLT(R) in the market for treating varicose
            veins by minimally invasive means,

      -     the compounding impact of the recurring revenue stream from
            disposable product sales to both new and existing customers,

      -     the impact of new sales management and development of our sales
            team, and

      -     the impact of increased acceptance of the EVLT(R) procedure by the
            medical community and expanded reimbursement coverage by health care
            insurers, including the establishment of reimbursement codes for
            EVLT(R) by the American Medical Association and the Center for
            Medicare and Medicaid Services, effective January 1, 2005.

Revenues for the period ended September 30, 2005 were negatively impacted by
Hurricanes Katrina and Rita, which we believe resulted in the deferral of three
to five EVLT(R) laser sales (representing revenues of between approximately
$100,000 to $150,000) in the affected regions. We expect that we will complete
these sales in future periods.

COST OF REVENUE AND GROSS PROFIT

Cost of revenue for the three months ended September 30, 2005 was $2,512,000,
increasing approximately $552,000, or 28%, from $1,959,000 for the three months
ended September 30, 2004. The increase in cost of revenue in 2005 was driven by
the corresponding increase in the number of lasers and disposable products sold,
offset, on a percentage of sales basis, by the leverage of fixed manufacturing
costs across a greater number of units, and improved material costs. Cost of
revenue, as a percentage of sales, decreased from 60% to 55% on a year-to-year
basis.

Gross profit for the three months ended September 30, 2005 was $2,071,000,
increasing approximately $754,000 from $1,317,000 from the three months ended
September 30, 2004. On a percent-of-sales-basis, the gross margin increased from
40% to 45%. The increase in gross profit in the third quarter of 2005 was driven
by fixed cost leverage of the incremental sales volume as well as improvements
in material costs. The Company believes that in the future, gross profit as a
percentage of sales may reach 60%, assuming increases in sales volume that may
occur after completion of the `777 patent litigation.


                                       40


OPERATING EXPENSES

RESEARCH AND DEVELOPMENT EXPENSES for the three months ended September 30, 2005
were $404,000, a decrease of $50,000, or 11%, from the three months ended
September 30, 2004. R&D expenditures are expected to remain at this level as we
continue to drive product functionality, cost improvements, and other
enhancements.

SELLING AND MARKETING EXPENSES for the three months ended September 30, 2005
were $2,081,000, an increase of $372,000, or 22%, over 2004, but decreased
$225,000, or 10%, from the second quarter of 2005. The increase from three
months ended September 30, 2004 was driven by higher sales commissions of
$112,000 resulting from the increased sales volume, and increased sales and
marketing expenditures in support of the sales efforts to drive the growing
commercialization of EVLT(R). Sales and marketing expenditures are expected to
increase with corresponding increases in revenue to support the continued
commercialization of EVLT(R).

GENERAL AND ADMINISTRATIVE EXPENSES for the three months ended September 30,
2005 were $1,812,000, an increase of $99,000, or 6%, from the same period in
2004, but decreased $281,000, or 13%, from the second quarter of 2005. The
increase from the three months ended September 30, 2004 was primarily
attributable to incremental legal fees of $224,000, which totaled $718,000 for
the quarter, as well as Sarbanes-Oxley compliance costs of $106,000, offset by
other administrative cost savings. Legal expenses included $676,000 for the
continuing cost of patent litigation we commenced during 2004 against four
competitors and the theft of trade secrets litigation we initiated in the fourth
quarter of 2003. We expect general and administrative costs to decrease to a
more normalized run rate in the fourth quarter after the discovery phase of the
`777 patent litigation is completed.

LOSS FROM OPERATIONS

Loss from operations for the three months ended September 30, 2005 was
$2,225,000, a decrease of approximately $333,000 from the three months ended
September 30, 2004, as incremental gross profit from an increased revenue base
offset the increase in legal costs related to our patent litigation.

NET LOSS

Net loss for the three months ended September 30, 2005 was $2,359,000 compared
to $2,573,000 for the third quarter of 2004. As a result of the relevant
accounting for the preferred stock and warrants issued in the private placement
financing completed on September 30, 2005, on an ongoing basis, the Company has
valued the 1,800,000 warrants using the Black-Scholes model and any subsequent
changes in the fair value will be included as Non-Cash Interest Expense for as
long as the warrants are outstanding.

NET LOSS APPLICABLE TO COMMON STOCKHOLDERS

Net loss applicable to common stockholders was $3,122,000, or $0.16 per share,
for the three months ended September 30, 2005 compared to $2,573,000, or $0.18
per share, for the three months ended September 30, 2004. For the three months
ended September 30, 2005, net loss applicable to common stockholders includes
non-cash charges of $763,000 in dividends accreted on preferred stock as a
result of a beneficial conversion feature and the fair value adjustment to
present preferred stock at its exchangeable value related to the September 30,
2005 Private Placement. The Company will pay cash dividends to holders of the
preferred stock on an ongoing basis at 6% for the first 18 months, 10% for
months 19 to 24, and 15% thereafter for as long as the preferred stock is
outstanding. In addition, because the dividend percentage is considered below
market for accounting purposes, the Company will record an incremental non-cash
dividend as an increase to the carrying value of the preferred stock to reflect
an effective interest rate of 16.5%.

     NINE MONTHS ENDED SEPTEMBER 30, 2005 COMPARED TO THE NINE MONTHS ENDED
                               SEPTEMBER 30, 2004

REVENUE

Diomed delivered revenue for the nine months ended September 30, 2005 of
$13,488,000, increasing approximately $4,079,000, or 43%, from $9,409,000 for
the nine months ended September 30, 2004. Revenue from the EVLT(R) product line
increased 69% over the nine months ended September 30, 2004. North America
EVLT(R) sales increased 87% including 96% growth in procedure products revenue.

For the nine months ended September 30, 2005, approximately $6,763,000, or 50%,
of our total revenue was derived from laser sales, as compared to approximately
$5,537,000, or 59%, in the nine months ended September 30, 2004. In the nine
months ended September 30, 2005, approximately $6,726,000, or 50%, of our total
revenues were derived from sales of disposable fibers and kits, accessories and
service, as compared to approximately $3,872,000, or 41%, in the nine months
ended September 30, 2004. We expect the proportion of revenue derived from
disposables to increase as we establish a larger base of installed lasers and
the number of EVLT(R) procedures performed grows.

The increase in revenue is attributable primarily to:

      -     increased penetration of EVLT(R) in the market for treating varicose
            veins by minimally invasive means,

      -     the compounding impact of the recurring revenue stream from
            disposable product sales to both new and existing customers,

      -     the impact of new sales management and development of our sales
            team, and

      -     the impact of increased acceptance of the EVLT(R) procedure by the
            medical community and expanded reimbursement coverage by health care
            insurers, including the establishment of reimbursement codes for
            EVLT(R) by the American Medical Association and the Center for
            Medicare and Medicaid Services, effective January 1, 2005.

Revenues for the period ended September 30, 2005 were negatively impacted by
Hurricanes Katrina and Rita, which we believe resulted in the deferral of three
to five EVLT(R) laser sales (representing revenues of between approximately
$100,000 to $150,000) in the affected regions. We expect that we will complete
these sales in future periods.

COST OF REVENUE AND GROSS PROFIT

Cost of revenue for the nine months ended September 30, 2005 was $7,325,000,
increasing approximately $1,503,000, or 26%, from $5,822,000 for the same period
in 2004. The increase in cost of revenue in 2005 was driven by the corresponding
increase in the number of lasers and disposable products sold, offset, on a
percentage of sales basis, by the leverage of fixed manufacturing costs across a
greater number of units and improved materials costs. Cost of revenue, as a
percentage of sales, decreased from 62% to 54% on a year-to-year basis.

Gross profit for the nine months ended September 30, 2005 was $6,163,000,
increasing approximately $2,576,000 from $3,587,000 for the same period in 2004.
On a percent-of-sales-basis, the gross margin increased from 38% to 46%. The
increase in gross profit was driven by fixed cost leverage of the incremental
sales volume as well as improvements in material costs. The Company believes
that in the future gross profit as a percentage of sales may reach 60%, assuming
increases in sales volume that may occur after completion of the `777 patent
litigation.


                                       42


OPERATING EXPENSES

RESEARCH AND DEVELOPMENT EXPENSES for the nine months ended September 30, 2005
were $1,151,000, an increase of $28,000, or 2%, from the same period in 2004.
R&D expenditures are expected to remain at this level as we continue to drive
product functionality, cost improvements, and other enhancements.

SELLING AND MARKETING EXPENSES for the nine months ended September 30, 2005 were
$6,694,000, an increase of $1,828,000, or 38%, over 2004. The increase was
driven by a significant expansion in the size of the sales force, higher sales
commissions of $300,000 resulting from the increased sales volume, and increased
sales and marketing expenditures in support of the sales efforts to drive the
growing commercialization of EVLT(R).

GENERAL AND ADMINISTRATIVE EXPENSES for the nine months ended September 30, 2005
were $5,476,000, an increase of $954,000, or 21%, from the same period in 2004.
The increase was primarily attributable to incremental legal fees of $635,000,
as well as Sarbanes-Oxley compliance of $182,000 and other administrative costs.
Legal expenses included the continuing cost of patent litigation against four
competitors commenced during 2004.

LOSS FROM OPERATIONS

Loss from operations for the nine months ended September 30, 2005 was
$7,157,000, an increase of approximately $233,000 from the same period in 2004,
as incremental gross profit from an increased revenue base was primarily offset
by increased legal costs related to our patent litigation.

INTEREST EXPENSE, NET

Interest expense for the nine months ended September 30, 2005 was $1,691,000,
compared to $37,000 for the same period in 2004. Interest expense in the nine
months ended September 30, 2005 included non-cash charges totaling $1,503,000
related to the amortization and acceleration of the debt discount related to the
first quarter 2005 conversion of $3,288,000 in debt issued in the September 28,
2004 equity and debt financing. As a result of the relevant accounting for the
preferred stock and warrants issued in the private placement financing completed
on September 30, 2005, on an ongoing basis, the Company has valued the 1,800,000
warrants using the Black-Scholes model and any subsequent changes in the fair
value will be included as Non-Cash Interest Expense for as long as the warrants
are outstanding.

NET LOSS

Net loss for the nine months ended September 30, 2005 was $8,847,000 compared to
$6,961,000 for the same period 2004. The expansion of Diomed's sales and
marketing efforts during the year drove incremental revenue, which was offset by
the increased legal costs and $1,503,000 in non-cash interest expense arising
from the amortization and acceleration of debt discount from the conversion of
$3,288,000 in debt in the first quarter 2005.

NET LOSS APPLICABLE TO COMMON STOCKHOLDERS

Net loss applicable to common stockholders for the nine months ended September
30, 2005 was $9,610,000, or $0.50 per share, compared to $6,961,000, or $0.50
per share, for the same period 2004. For the nine month period ended September
30, 2005, net loss applicable to common stockholders includes non-cash charges
of $763,000 in dividends accreted on preferred stock as a result of a beneficial
conversion feature and the fair value adjustment to present preferred stock at
its exchangeable value related to the September 30, 2005 private placement. The
Company will pay cash dividends to holders of the preferred stock on an ongoing
basis at 6% for the first 18 months, 10% for months 19 to 24, and 15% thereafter
for as long as the preferred stock is outstanding. In addition, because the
dividend percentage is considered below market for accounting purposes, the
Company will record an incremental non-cash dividend as an increase to the
carrying value of the preferred stock to reflect an effective interest rate of
16.5%.

             FISCAL YEAR ENDED DECEMBER 31, 2004 COMPARED TO FISCAL
                          YEAR ENDED DECEMBER 31, 2003


REVENUE

Diomed delivered revenues for the year ended December 31, 2004 of $13,385,000,
increasing approximately $4,186,000, or 46%, from $9,199,000 for the year ended
December 31, 2003. Revenue from EVLT(R) disposable procedure kits increased
100%, demonstrating the continued and growing acceptance of EVLT(R) by the
medical community and patients alike.

In 2004, approximately $7,838,000, or 59%, of our total revenues, were derived
from laser sales, as compared to approximately $5,726,000, or 62%, in 2003. In
2004, approximately $5,546,000, or 41%, of our total revenues were derived from
sales of disposable fibers and kits, accessories and service, as compared to
approximately $3,473,000, or 38% in 2003. We expect the proportion of revenue
derived from disposables to increase as we establish a larger base of installed
lasers and the number of EVLT(R) procedures performed grows.

The increase in revenue is attributable primarily to:

      - increased penetration in the EVLT(R) market,

      - the compounding impact of the recurring revenue stream from
        disposable sales to both new and existing customers,

      - the impact of new sales management and development of our sales
        team, and

      - the impact of increased acceptance of the EVLT(R) procedure and
        expanded reimbursement coverage by health care insurers, including
        the recent establishment of reimbursement codes for EVLT(R) by the
        American Medical Association and the Center for Medicare and
        Medicaid Services.

COST OF REVENUE AND GROSS PROFIT

Cost of revenue for the year ended December 31, 2004 was $7,920,000, increasing
approximately $2,047,000, or 35%, from $5,873,000 for the year ended December
31, 2003. Cost of revenue, as a percentage of sales, decreased from 64% to 59%
on a year-to-year basis.

The increase in cost of revenue in 2004 was driven by:

      - the corresponding increase in the number of lasers and disposable
        products sold, offset, on a percentage of sales basis, by the
        leverage of fixed manufacturing costs across a greater number of
        units,

      - improved materials costs, partially offset by foreign exchange
        impact, and

      - full year impact of royalties and amortization of the intangible
        asset from the EVLT(R) patent acquisition completed in September
        2003.

Gross profit for the year ended December 31, 2004 was $5,464,000, increasing
approximately $2,139,000 from $3,325,000 for the year ended December 31, 2003.
On a percent-of-sales-basis, the gross margin increased from 36% to 41%. The
increase in gross profit in 2004 was driven by incremental sales volume, as well
as improvements in material costs.

OPERATING EXPENSES

Research and development expenses for the year ended December 31, 2004 increased
by 99% to $1,695,000 from $850,000 from the year ended December 31, 2003. This
increase was largely due to our increased focus on improving the
feature-function and manufacturability of our lasers and disposable kits when
compared to 2003 operations, which were affected by cash constraints prior to
the equity financing we completed in the fourth quarter of 2003. We expect that
research and development spending will remain at this elevated level, as we
continue to focus on product cost reductions and improvements in the
feature-function of our products.

Selling and marketing expenses for the year ended December 31, 2004 were
$7,161,000, increasing approximately $3,105,000, or 77%, from $4,056,000 for the
year ended December 31, 2003. The increase was primarily driven by personnel
costs of $1,800,000, caused by a doubling in the size of the sales force, higher
sales commissions resulting from increased sales volume, restructuring of the
sales field leadership and sales field organization including sales leadership
termination payments and recruiting costs and increased marketing expenditures
of $750,000, primarily for trade shows and advertising in support of the sales
efforts to drive the growing commercialization of EVLT(R). In 2005, we
anticipate increased expenses resulting from the larger sales organization,
increased commissions due to volume, and increased spending levels in marketing
programs to support the continued growth in commercialization of EVLT(R).


                                       44


General and administrative expenses for the year ended December 31, 2004 were
$6,422,000 increasing approximately $2,022,000, or 46%, from $4,400,000 for the
year ended December 31, 2003. The increase was primarily attributable to
incremental legal fees of $1,200,000, as well as sales volume-based product
liability insurance costs and infrastructure enhancements. Legal costs included
the cost of patent infringement litigation against AngioDynamics, Vascular
Solutions, Total Vein Solutions, and CoolTouch, as well as continuing costs of
litigation against Vascular Solutions in trade secrets suit litigation commenced
by the Company in the fourth quarter of 2003. In 2005, we anticipate general and
administrative expenses to remain at this elevated level as we continue to incur
legal fees in connection with the intellectual property infringement actions
lawsuits we filed against AngioDynamics, Vascular Solutions, Total Vein
Solutions and New Star Lasers (a/k/a Cool Touch).

LOSS FROM OPERATIONS

As a result of the factors outlined above, the loss from operations for the year
ended December 31, 2004 was $9,813,000, increasing approximately $3,833,000, or
64%, from $5,980,000 for the year ended December 31, 2003, as increasing costs
were partially offset by increased operating revenue.

INTEREST EXPENSE, NET

Interest expense for the year ended December 31, 2004 was $264,000, compared to
$13,902,000 for the year ended December 31, 2003, and included $109,000 in
non-cash charges for debt discounts, the beneficial conversion feature and debt
financing costs related to the October 2004 equity and convertible debt
financing. Interest expense will continue to increase in 2005 as a result of the
amortization of these items, acceleration of deferred financing and discount due
to conversion of convertible debt after year-end and due to the actual interest
accrued on the debt. Interest expenses for 2003 included $12,894,000 in non-cash
charges for debt discounts, the beneficial conversion feature and debt financing
costs related to our financing activities during 2003. Cash-based interest
expense in 2003, in the amount of $1,008,000, included $783,000 in amortization
of debt financing costs and $132,000 in interest expense on notes related to our
December 2002 debt financing. These charges did not continue in 2004, as the
December 2002 notes were fully repaid in September, 2003, and notes we issued
during 2003 (including all accrued interest thereon) were fully converted into
common stock in November 2003. In addition, 2003 interest expense included
$72,000 related to the $936,000 promissory note we owed to Axcan Pharma, which
we paid on January 2, 2004, in accordance with the terms under the note.

INCOME TAXES

For the years ended December 31, 2004 and 2003, we included no provision for
foreign, federal or state income taxes, as we incurred net operating losses.

NET LOSS

As a result of the above, the net loss (adjusted for the 1:25 reverse split that
we implemented effectively June 17, 2004) applicable to common stockholders for
the year ended December 31, 2004 was $10,077,000, or $0.68 per share, compared
to a net loss of $19,881,000, or $8.99 per share, in the year ended December 31,
2003. The 2003 net loss included $12,894,000 in non-cash interest expense
arising from debt discounts and the beneficial conversion feature related to the
bridge financings in December 2002 through September 2003.

                         LIQUIDITY AND CAPITAL RESOURCES

                                     SUMMARY


Since our inception through September 30, 2005, we had an accumulated deficit of
approximately $78 million, including $17.5 million in non-cash interest expense.
We may continue to incur operating losses due to spending on research and
development programs, legal fees in support of our intellectual property rights,
clinical trials, regulatory activities, sales, marketing and administrative
activities. This spending may not correspond with any meaningful increases in
revenues in the near term, if at all. As such, these costs may result in losses
until such time as we generate sufficient revenue to offset such costs. We have
financed our operations primarily through private placements of common stock and
preferred stock, private placements of convertible notes and short term notes
and through credit arrangements.


               TRANSACTIONS IN 2005

The following summarizes our capital financing transactions during 2005:


                                       45


EXERCISE OF WARRANTS


During the nine month period ended September 30, 2005, holders of warrants
exercised their warrants to purchase 192,811 shares of common stock. The average
price per share for the warrants exercised during this period was $2.10. We
received proceeds from the exercise of these warrants because the holders did
not elect to use their "cashless exercise" rights, however, in the future,
warrant holders may exercise warrants using the cashless exercise option, in
which case we will not receive cash proceeds from the exercise of warrants,
although we will issue fewer shares than the number of warrant shares being
exercised, at a rate determined by the applicable cashless exercise formula.


ISSUANCE OF WARRANTS TO LUMINETX CORPORATION

In connection with our distribution agreement we entered into with Luminetx
Corporation pursuant to which we shall act as distributor of Luminetx's
VeinViewer(TM) system , on August 5, 2005, we issued to Luminetx warrants to
purchase up to 600,000 shares of our common stock. The warrants have an exercise
price of $2.90 per share, become exercisable when the underlying shares are
listed with the American Stock Exchange and cease to be exercisable on the
earlier of five years from full vesting, August 5, 2011 and the date of
termination of the distribution agreement. Fifty percent of the warrants were
immediately exercisable when issued (subject to prior listing of the underlying
shares with the AMEX), and the remainder of the warrants will become exercisable
when both (i) Luminetx has produced at least 100 units of the VeinViewer(TM)
system and (ii) we have accepted delivery of at least 25 units of the
VeinViewer(TM) system.

PRIVATE PLACEMENT FINANCING COMPLETED SEPTEMBER
30, 2005

On September 30, 2005, we entered into and completed a financing transaction
pursuant to which we issued and sold 4 million shares of preferred stock at a
purchase price of $2.50 per share. We also issued to the investors warrants to
purchase an aggregate of 1.6 million shares of common stock, at an exercise
price of $2.50 per share (subject to antidilution adjustments). In addition to
the warrants we issued to the investors, we also issued warrants to purchase up
to an aggregate of 200,000 shares of common stock to the three holders of our
convertible debentures we issued in October 2004, as an inducement to, and in
consideration for, the debenture holders' waiver of certain negative covenants
that would have been violated by the financing had the debenture holders not
waived them.

We received aggregate gross proceeds of $10 million from the sale of these
securities (approximately $9.5 million net of financing costs, not including
legal fees or registration expenses). We are using the proceeds of the September
2005 financing for our general working capital purposes. We agreed with the
investors that we would not use these proceeds to (i) increase director or
executive compensation or make any loan or other advance to any officer,
employee, director, stockholder or other affiliate, in each case without prior
board approval, (ii) pay dividends (except on the preferred stock), (iii)
purchase debt or equity securities, including redeeming our own securities
(other than the preferred stock), (iv) make investments not directly related to
our current business or (v) repay debt (other than trade payables in the
ordinary course of our business).

The following summarizes the principal terms of the transaction:

Preferred Stock

We entered into a share exchange agreement with the investors who purchased
preferred stock, pursuant to which the investors may exchange shares of
preferred stock for shares of common stock. Each share of preferred stock may be
exchanged for that number of shares of common stock that equals the issue price
of the preferred stock ($2.50) divided by an exchange rate, initially set at
$2.50 and subject to reduction in the case of dilutive issuances.

The antidilution adjustment provides that if we sell common stock (or the right
to acquire common stock) for a price lower than the then-current exchange rate,
the exchange rate will be reduced to the amount paid for the shares of common
stock, subject to a floor of $2.17, unless the stockholders of the Company
approve the elimination of the floor price. We agreed to propose to our
stockholders that the floor price be eliminated. If the stockholders approve
this proposal and we make a dilutive issuance, then the exchange rate for the
preferred stock may be decreased, first to the $2.17 floor price, then to the
price determined by a weighted average formula set forth in the exchange
agreement.

We agreed to pay liquidated damages to the investors if we fail to comply with
an investor's request to exchange preferred stock for common stock, if the
registration statement covering the common stock underlying the preferred stock
and the warrants is not declared effective by the Commission within 120 days of
the September 30, 2005 closing date (or, after being declared effective by the
Commission, is unavailable to the investors for the resale of their common
stock) or if the common stock is suspended from trading or is not listed on an
exchange. The liquidated damages in each case will be equal to 3% per month of
the aggregate purchase price paid by investors for the preferred stock.

If certain redemption events set forth in the exchange agreement occur, the
investors have the right to redeem their shares of preferred stock for cash at a
20% redemption premium over the issue price. These events include those events
entitling the investors to receive liquidated damages if not remedied during
applicable cure periods, as well as the failure to remove restrictive legends
upon an investor's request when permitted under applicable law, our announcement
that we intend not to issue common stock in exchange for preferred stock,
bankruptcy events, a default under indebtedness of the Company or one of our
material agreements or a concentration of ownership of the Company's capital
stock of 35% which continues for 30 days. After five years, we also have the
right to redeem the preferred stock at a 20% premium over the issue price.


                                       46


The holders of outstanding shares of preferred stock are entitled to cumulative
annual dividends at the rate of: (i) 6%, for the first 18 months following the
initial sale of preferred stock, (ii) 10% from the 19th through the 24th month
following the initial sale and (iii) 15% after the 24th month following the
initial sale. The dividends shall accrue from day-to-day on each share of
preferred stock, whether or not earned or declared, and shall accrue until paid.
We may pay the dividends with either cash or, if certain conditions are met,
shares of common stock, valued at the volume weighted average price for the
ten-day period immediately prior to the dividend payment date. The dividends
will not accrue on any days where the volume weighted average price of the
common stock for the 30 prior trading days equals or exceeds $6.25 (subject to
adjustment for stock splits, stock dividends and similar events). The conditions
which must be met for either the payment of dividends in the form of common
stock or the suspension of dividend accrual are that, if certain conditions are
met, the shares of common stock for which the preferred stock may be exchanged
under the exchange agreement (in the case of suspension of dividends) or which
may be issued as dividends (in the case of payment of dividends in the form of
common stock) are subject to an effective registration statement, the shares of
common stock for which the preferred stock may be exchanged and the common stock
underlying warrants is authorized and reserved for issuance and listed on a
trading market, none of the events giving rise to an investor's right to redeem
the preferred stock under the exchange agreement shall have occurred and not
been cured and we do not owe the investors more than $15,000, in the aggregate,
under the transaction documents for the private placement financing.

Each holder of preferred stock is entitled to one vote per share of issued and
outstanding preferred stock owned by such holder on the record date for the
determination of stockholders entitled to vote, and the holders of the preferred
stock and the common stock shall vote together as a single class (except where
the Delaware General Corporation Law provides that a separate vote of the
holders of preferred stock is required for approval of certain matters, in which
case a majority of the shares of preferred stock outstanding shall be required
for approval).

The preferred stock is preferred over the common stock, and any class or series
of capital stock that our board of directors may create in the future, as to the
assets of the Company available for distribution to the stockholders in the
event of the liquidation, dissolution or winding up of the Company, the sale of
all or substantially all of the assets of the Company or the merger or
consolidation of the Company with another entity that results in either the
stockholders of the Company having less than 50% of the outstanding voting
securities of the successor company in the merger or combination transaction or
the members of the board of directors of the Company constituting 50% or less
than the members of the board of directors of the successor company in the
merger. Upon the occurrence of one of the transactions listed above, the holders
of preferred stock are to receive, before any distribution or payment is made to
any holders of common stock, the greater of: (i) $3.00 per share of preferred
stock, plus all accrued and unpaid dividends thereon, and (ii) such amount per
share of preferred stock that would have been payable had each share of
preferred stock been tendered in exchange for common stock immediately prior to
the transaction.

Warrants

The warrants are exercisable for five years from the date of listing of the
underlying shares of common stock with the AMEX at an exercise price of $2.50
per share, subject to reduction in the case of dilutive issuances. The
antidilution adjustment provides that if we sell common stock (or the rights to
acquire common stock) for a price lower than the then-current exercise price,
the exercise price will be reduced to the amount paid for the shares of common
stock we issued at such lower price, subject to a floor of $2.12, unless the
stockholders of the Company approve the elimination of the floor price. We
agreed to propose to its stockholders that the floor price be eliminated. If the
stockholders approve this proposal and we make a dilutive issuance, then the
exercise price of the warrants may be decreased, first to the floor price, then
to the weighted average price of the securities issued after giving effect to
the dilutive issuance. If the exercise price of the warrants is so adjusted,
then there will concurrently be an adjustment to the number of shares for which
the warrant will be exercisable, by dividing the product of the former exercise
price multiplied by the number of shares underlying the warrant by the adjusted
exercise price.

The holders of the warrants may exercise their warrants by means of a "cashless
exercise" instead of paying cash to us upon exercise, in which case the holder
shall be entitled to receive a certificate for the number of warrant shares
equal to the quotient obtained by dividing [(A-B)(X)] by (A), where;


              A = the VWAP (as defined in the warrant agreement) on the date of
                  exercise;


              B = the then-current exercise price of the warrant; and

              X = the number of warrant shares issuable upon exercise of the
                  warrant by means of a cash exercise rather than a cashless
                  exercise


                                       47


Because of this cashless exercise feature, we may not receive any proceeds from
the exercise of warrants (although we will issue a net number of shares that is
less than the total of 1.8 million aggregate face amount of the warrants).
Assuming, however, that all of the warrants are exercised for cash at our
exercise price of $2.50 per share, then we will receive a total of $4.5 million
for the exercise of the warrants, and we will issue 1.8 million shares of common
stock. We will use the proceeds of the exercise of warrants for our general
working capital purposes.

Limitations on Ownership

The terms of the preferred stock and the warrants that we issued in the
September 30, 2005 financing limit the ability of any investor to exchange
preferred stock (and for the Company to issue shares of common stock as
dividends) and/or exercise warrants to the extent that the shares of common
stock so issued would exceed 4.99% (or, in the case of certain investors who
already owned over 4.99% of our common stock prior to the financing, 9.99%) of
the shares of common stock outstanding, unless this limitation is waived in
advance by the investor by providing not less than 61 days prior written notice
to us.

Registration of Common Stock

We agreed to seek the registration of the common stock underlying the preferred
stock and the warrants with the Commission. We undertook to file a registration
statement for such registration within 45 days of completion of the financing,
and agreed that if the Commission does not declare this registration statement
effective within 120 days of completion of the financing, we will pay liquidated
damages to the investors. The liquidated damages will be equal to 3% per month
of the aggregate purchase price paid by the investors for the preferred stock.
The registration statement of which this prospectus is a part is the
registration statement intended to satisfy our obligations to the investors in
the September 2005 financing.

Accounting for September 30, 2005 Financing
Transaction


In accordance with Emerging Issues Task Force (EITF) number 00-27, "Application
of Issue No. 98-5 to Certain Convertible Instruments" (EITF 00-27), we allocated
the proceeds received in the financing between the preferred stock and the
warrants based on their relative fair values. Then we compared the proceeds
allocated to the preferred stock to the fair value of the common stock that
would be received upon exchange to determine if a beneficial conversion feature
existed. We determined that a beneficial conversion feature of $381,328 existed
and in accordance with EITF 00-27 accreted that amount immediately to the value
of the preferred stock, as the preferred stock is immediately exchangeable.
Further, as the fair value was less than the exchange value, we recorded
$381,328 as an increase to the carrying value with an offset to additional
paid-in capital. In accordance with EITF 98-5, this combined adjustment of
$762,656 is analogous to a dividend and recognized as a return to the
shareholders and has therefore been included in Preferred Stock Dividends in our
calculation of Net Loss Applicable to Common Stockholders and Basic and Diluted
Net Loss Per Share.

We also reduced the carrying value by $765,000 of the preferred stock for
specific incremental costs directly attributable to the transaction, including
investment banking, legal and professional fees.


EITF 00-19 "Accounting for Derivative Financial Instruments Indexed to, and
Potentially Settled in, a Company's Own Stock" (EITF 00-19) requires
freestanding contracts that are settled in a company's own stock, including
common stock warrants, to be designated as an equity instrument, assets or
liability. Under the provisions of EITF 00-19, a contract designated as an asset
or liability must be carried at fair value until the contract meets the
requirements for classification as equity, until the contract is exercised or
until the contract expires.


According to the terms of the transaction, we are subject to certain liquidated
damages under our registration rights agreement with the investors if we can not
obtain and maintain effectiveness of a registration statement. Since the
liquidating damages had no contractual maximum, we determined that the
liquidated damages were onerous and thus could result in net-cash settlement of
the transaction in accordance with EITF 00-19. We valued the warrants using the
Black-Scholes model. We recorded a warrant liability of $1,861,328 based on the
relative fair value in accordance with EITF 00-27. Because the warrants are
classified as a liability, any subsequent changes in fair value will be recorded
as Non-Cash Interest Expense in the subsequent Statements of Operations until
the warrants are exercised, terminated or expired.

As the preferred stock includes stated dividend rates that increase over time,
from a rate considered below market, we will amortize an incremental amount
which together with the stated rate for the period results in a constant
dividend rate in accordance with Securities Exchange Commission Staff Accounting
Bulletin Topic 5Q. We determined that the present value of the incremental
dividends of $1,371,429 will be amortized over the period preceding the
perpetual dividend rate using an effective interest rate of 16.5%. We will
increase the carrying value of the preferred stock with an offset to Additional
Paid-in Capital periodically and reduce the carrying value when paid. These
dividends will be included in Preferred Stock Dividends in our calculation of
Net Loss Applicable to Common Stockholders and Basic and Diluted Net Loss Per
Share.



                                       48


In addition to the warrants we issued to the investors, we also issued warrants
to purchase up to 200,000 shares of common stock to the three holders of our
convertible debentures we issued in October 2004, as an inducement to, and in
consideration for, the debenture holders' waiver of certain negative covenants
that would have been violated by the financing had the debenture holders not
waived. These warrants were valued using the Black-Scholes model. As a result,
we recorded an additional debt discount to the September 28, 2004 convertible
debentures of $256,969 which will be amortized to non-cash interest expense over
the remaining term of the convertible debentures, which mature in October 2008,
unless previously converted or redeemed.

                              TRANSACTIONS IN 2004

The following summarizes our capital financing transactions during 2004:

OFFERING TO STOCKHOLDERS AS OF AUGUST 29, 2003

On April 20, 2004, we completed our offering to those persons who held shares of
our common stock as of August 29, 2003, raising the approximate $3 million
maximum in additional equity financing (approximately $2,728,000 after related
expenses). We are using the proceeds from the targeted offering for general
working capital purposes, including supporting our continued growth and
intellectual property strategies. The targeted offering, for 1,188,470 shares of
the Company's common stock at $2.50 per share (after giving effect to the 1:25
reverse split effective June 17, 2004), allowed stockholders to purchase one
share of the Company's common stock for each share of common stock held on
August 29, 2003. The targeted offering also included an "over-subscription
right" which allowed stockholders to purchase additional shares to the extent
the "basic rights" were not fully subscribed.

We filed a registration statement to register the shares to be offered in the
targeted offering. The SEC declared that registration statement effective on
February 13, 2004.

PRIVATE PLACEMENT EQUITY AND DEBT FINANCING ENTERED INTO
SEPTEMBER 28, 2004

On September 28, 2004, we entered into definitive agreements for the sale and
issuance of convertible debentures, common stock and warrants to purchase common
stock to certain accredited investors in a private placement financing
transaction. On October 25, 2004, after receiving approval to list the shares
from the AMEX, we completed this transaction, pursuant to which we raised gross
proceeds of approximately $10.6 million. We received net proceeds of
approximately $9.8 million, before related legal and registration expenses of
approximately $300,000. We are using the proceeds from the 2004 financing
transaction for general working capital purposes.

The following summarizes the principal terms of the transaction:

Variable Rate Convertible Debentures

We issued an aggregate of $7 million principal amount of convertible debentures
at par. The convertible debentures bear interest (payable quarterly in arrears
on March 31, June 30, September 30 and December 31) at a variable rate of 400
basis points over six-month LIBOR and mature four years from the date of
issuance.

The debentures are convertible at any time at the option of the holder into
common stock at a conversion price of $2.29 per share, which was 120% of the
$1.91 per share closing price of the common stock on the AMEX on the trading day
prior to the date that we and the investors signed the definitive purchase
agreements The conversion price is subject to certain adjustments, for dilutive
transactions and for recapitalizations of our capital stock.

Subject to certain conditions, the debentures will also be convertible at the
Company's option at any time after the first anniversary of the issuance date if
the closing price of the Company's common stock equals or exceeds 175% of the
conversion price for at least 20 consecutive trading days. Also subject to
certain conditions, upon maturity, the Company may cause the holders to convert
the entire principal amount of debentures outstanding into shares of common
stock, at a price per share equal to the lesser of the stated conversion price
and 90% of the volume weighted average trading price of its common stock for the
20 days prior to the maturity date.

After the first year and at our option, subject to certain conditions, interest
may be paid in shares of common stock in lieu of cash, at a conversion price
which is based on the closing prices of the common stock on the fifth through
first trading days immediately preceding the interest payment date. The
conversion rate for interest will be discounted by 10% if we obtain stockholder
approval of this discount.


During the first quarter of 2005, the holders of $3.288 million principal amount
of debentures elected to convert that amount of debentures (including accrued
interest of approximately $31,108) into common stock at $2.29 per share.
Accordingly, we issued 1,449,392 shares of common stock to these debenture
holders, and $3.712 million principal amount of debentures was outstanding as of
November 30, 2005.



                                       49


Common Stock

We also issued and sold a total of 2,362,420 shares of common stock at a
purchase price of $1.53 per share, which is 80% of the closing price of the
common stock on the AMEX on the trading day prior to the date that we and the
investors signed the definitive purchase agreements. Accordingly, we received an
aggregate purchase price of $3,614,503 for these shares.

Warrants to Purchase Common Stock

In the private placement financing we completed on October 25, 2004, we issued
warrants to purchase up to 1,832,461 shares of common stock to the investors who
purchased convertible debentures and warrants to purchase up to 1,181,210
additional shares of common stock to the investors who purchased common stock.
The warrants are exercisable for five years from the date of issuance at an
exercise price of $2.10 per share, which is 110% of the $1.91 per share closing
price of the common stock on the AMEX on the trading day prior to the date that
we and the investors signed the definitive purchase agreements. The exercise
price is subject to certain adjustments, including future sales of securities
below the exercise price.


During 2004, holders of 163,399 warrants exercised these warrants, at an
exercise price of $2.10 per share. Accordingly, we issued 163,399 shares of
common stock to these warrant holders and received $343,138 in aggregate
proceeds. Subsequent to year-end 2004, during the nine months ended September
30, 2005, the holders of 192,811 warrants exercised these warrants, at an
exercise price of $2.10 per share. Accordingly, we issued 192,811 shares of
common stock to these warrant holders and received $404,903 in aggregate
proceeds.


Registration of Common Stock

The Company agreed to undertake registration with the Commission of the common
stock and common stock underlying the convertible debentures and warrants. We
filed a registration statement with the Commission on November 24, 2004 covering
these shares and the Commission declared that registration statement effective
on December 6, 2004.

                       CHANGES IN CAPITAL STOCK STRUCTURE

On September 30, 2005, we designated the rights and preferences of the preferred
stock to be issued in the September 30, 2005 financing. We designated 4,200,000
shares of preferred stock out of the 20,000,000 authorized but unissued shares
of preferred stock available for purposes of the financing, and we issued
4,000,000 of these shares of preferred stock on September 30, 2005 to the
investors in the financing at a purchase price of $2.50 per share (200,000
shares designated remain unissued). As a result, we now have 15,800,000 shares
of authorized but unissued shares of preferred stock.

On June 15, 2004, we held our 2004 Annual Meeting of Stockholders, where our
stockholders voted to permit the Board of Directors, in their discretion, to
effect a one-for-twenty-five reverse stock split of our common stock. On June
16, 2004, the Board of Directors approved the reverse stock split effective June
17, 2004. Additionally, our stockholders approved the reduction in our
authorized shares of common stock from 500 million to 50 million which we
implemented concurrent with the reverse stock split.

                           CASH POSITION AND CASH FLOW


Our cash and short term investment balances were approximately $16,569,000 as of
September 30, 2005. We had cash balances of approximately $14,436,000 and
$13,398,000 at December 31, 2004 and December 31, 2003, respectively.


We have financed our operations primarily through private placements of common
and preferred stock, convertible and short-term notes, and through credit
arrangements, including the following:

      o  In September 2003, we entered into an equity financing transaction
         pursuant to which we raised gross proceeds of $22,000,000 and
         satisfied $1,200,000 in debt, which we had issued in a May 2003
         bridge financing. Of the cash proceeds raised in 2003, we utilized
         approximately $8.6 million as follows: $2,250,000 in initial
         payments to acquire the exclusive rights to the EVLT(R) patent,
         $2,132,000 to retire the notes we issued in December 2002, $438,000
         to retire short-term notes, $1,160,000 in equity financing costs,
         $1,141,000 in the reduction of trade payables, $150,000 in the
         Augenbaum litigation settlement, and $1,329,000 in working capital
         from September through December 2003.

      o  In April 2004, we completed a targeted offering of common stock
         (priced at $0.10 per share) to the holders of common stock of record
         as of August 29, 2003. We raised gross proceeds of approximately
         $3,000,000 (approximately $2,728,000 after offering costs) in the
         targeted offering.

      o  In October 2004, we completed a common stock and convertible debt
         financing transaction pursuant to which we raised gross proceeds of
         approximately $10,500,000 (approximately $9,400,000 after financing
         costs) in this financing transaction.


                                       50


We are using the balance of these proceeds for general working capital purposes,
including pursuing our intellectual property strategy.

CASH USED IN OPERATIONS

Cash used in operations for the year ended December 31, 2004 was $8,731,000. The
cash used in operations reflects the net loss for the year of $10,077,163 and
primarily relates to the significant expansion in the size of the sales force
and external marketing initiatives of $3,105,000 in support of the
commercialization of EVLT(R), as well as $1,200,000 in legal fees incurred in
asserting our EVLT(R) patent.


Cash used in operations for the nine months ended September 30, 2005 was
$6,729,000. The cash used in operations reflects the net loss of $8,847,000
reduced by the non-cash interest expense of $1,503,000 and working capital
changes including $300,000 in 2004 incentive compensation payments which are not
expected to recur during the year.


CASH USED IN INVESTING


Cash used in investing activities for the year ended December 31, 2004 was
approximately $519,000, primarily related to demonstration equipment and
customer trial programs. Cash used in investing activities for the nine months
ended September 30, 2005 was approximately $2,655,000; including purchases of
available for sale securities of $1,749,000, a promissory note of $500,000
issued to us by Luminetx and purchases of and computer and demonstration
equipment.


CASH PROVIDED BY FINANCING

Cash provided by financing activities for the year ended December 31, 2004 was
approximately $10,324,000. This primarily includes the $2,728,000 net proceeds
we received from the targeted offering completed on April 20, 2004, the
$9,505,000 net proceeds we received from the 2004 private placement debt and
equity financing completed on October 25, 2004 and the $343,000 we received from
the exercise of warrants we issued in the 2004 private placement. Proceeds from
these financings were partially offset by the first quarter retirement of a
promissory note to Axcan Pharma in the aggregate principal amount of $936,000
and a reduction in the borrowing outstanding under the UK tradeline facility
with Barclay's Bank ($262,000). Financing activities also included payments of
$1,000,000 related to current maturities of the EVLT(R) technology acquisition
obligation.


Cash provided by financing activities for the nine months ended September 30,
2005 was 9,808,000. This includes $10 million raised in the September 30, 2005
private placement, $405,000 which we received from the exercise of warrants we
issued in the 2004 equity and debt financing and $193,000 in bank borrowings,
offset by $750,000 in payments related the current maturities of the EVLT(R)
technology acquisition obligation.


BANK LINES OF CREDIT


Diomed, Ltd., the Company's United Kingdom-based subsidiary, utilizes a an
overdraft facility as well as an accounts receivable line of credit with
Barclays Bank, limited to the lesser of (GBP)100,000 ($177,000 as of September
30, 2005) or 80% of eligible accounts receivable. The credit line bears interest
at a rate of 3% above Barclays' base rate of 4.5% at September 30, 2005 and
borrowings are due upon collection of receivables from customers. As security
for the line of credit, Barclays Bank has a lien on all of the assets of Diomed
Ltd., excluding certain intellectual property. As of September 30, 2005 and
September 30, 2004, there was approximately $193,000 and zero, respectively
outstanding under these credit facilities. As of December 31, 2004, there were
no amounts outstanding under this line. At December 31, 2003, there was
approximately $262,000 outstanding under this credit facility.


We formerly had a line of credit with Silicon Valley Bank, which we opened in
June 2004. However, as a result of the private placement debt and equity
financing that we completed on October 25, 2004, we terminated this line of
credit. At no time during the term of the line of credit did we fail to comply
with any of our covenants in the line of credit, nor did we draw down on the
line, and accordingly, there were no amounts outstanding at the time of
termination.

FUTURE AVAILABILITY OF CREDIT


As of September 30, 2005, other than the security under the Barclays Bank line
of credit, our assets were not the subject to any liens or encumbrances.
Therefore these unencumbered assets may be available as security for credit
facilities we may seek in the future. However, under the terms of the
convertible debentures that we issued on October 25, 2004, we agreed that, so
long as at least 10% of the original principal amount of any debenture was
outstanding, we would not incur indebtedness or create a lien that is senior to
or having an equal priority with our obligations under the debentures, except
for purchase money security interests and otherwise to the extent that we do so
in the ordinary course of our business. As of November 30, 2005, the three
investors who purchased debentures continued to hold debentures of at least 10%
of the original principal amount.



                                       51


COMMITMENT FOR LUMINETX INVESTMENT


On August 5, 2005, we entered into a distribution agreement with Luminetx,
pursuant to which Luminetx appointed us a distributor and granted us the
exclusive right to distribute and sell Luminetx' patented biomedical imaging
system known as the VeinViewer(TM) Imaging System for physicians who perform
sclerotherapy, phlebectomies or varicose vein treatments, initially in the
United States and the United Kingdom, with additional territories to be
negotiated as VeinViewer(TM) receives regulatory clearance in other countries,
on terms to be agreed. We agreed to loan $1 million to Luminetx under the
distribution agreement. We loaned $500,000 to Luminetx on August 5, 2005 and
will invest the remaining $500,000 in Luminetx when it delivers to us a minimum
number of VeinViewer(TM) systems, as specified in our distribution agreement. We
converted our $500,000 loan to Luminetx into 250,000 shares of Luminetx
preferred stock, convertible into common stock on a share-for-share basis, and
warrants to purchase 50,000 shares of Luminetx common stock at $2.00 per share,
exercisable for five years, as part of an $11 million private placement
financing that Luminetx announced on November 4, 2005. We will invest the
remaining $500,000 of our loan commitment to Luminetx for preferred stock and
warrants on the same terms. We intend to fund the investment in Luminetx out of
our working capital resources.


           CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition, results of operations,
and cash flows are based on our consolidated financial statements, which have
been prepared in accordance with accounting principles generally accepted in the
U.S. The preparation of these financial statements requires us to make estimates
and judgments that affect the reported amounts of assets, liabilities, revenues
and expenses, and related disclosure of contingent assets and liabilities. On an
on-going basis, we evaluate these estimates, including those related to bad
debts, inventory valuation and obsolescence, intangible assets, income taxes,
warranty obligations, contingencies and litigation. Additionally, we use
assumptions and estimates in calculations to determine stock-based compensation.
We base our estimates on historical experience and on various other assumptions
that we believe to be reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. Actual results may
differ from these estimates under different assumptions or conditions.

Our critical accounting policies include:

      -  revenue recognition;

      -  allowance for doubtful accounts;

      -  warranty obligation;

      -  allowances for excess and obsolete inventory; and

      -  valuation of long-lived and intangible assets.

         Revenue Recognition. We derive our revenue from primarily two sources:
(i) revenues from products including lasers, instrumentation, and disposables,
and (ii) revenues from service. We recognize revenue on products and services
when persuasive evidence of an arrangement is in place, the price is fixed or
determinable, collectability is reasonably assured and title and risk of
ownership has been transferred. Transfer of title and risk of ownership
generally occurs when the product is shipped to the customer or when the
customer receives the product, depending on the nature of the arrangement. We
currently provide for the estimated cost to repair or replace products under
warranty at the time of sale. Service revenue is recognized as the services are
performed.

      Allowance for Doubtful Accounts. Accounts receivable are customer
obligations due under normal trade terms. We sell our products to private
physicians, hospitals, health clinics, distributors and OEM customers. We
generally require signed sales agreements, non-refundable advance payments and
purchase orders, and in certain circumstances, depending upon the type of
customer, letters of credit. Some customers seek equipment financing from third
party leasing agents. Accounts receivable are stated at the amount billed to the
customer less a valuation allowance for doubtful accounts.

      Senior management reviews accounts receivable on a monthly basis to
determine if any receivables could potentially be uncollectible. We include
specific accounts receivable balances that are determined to be uncollectible,
along with a general reserve, in our overall allowance for doubtful accounts.
After all attempts to collect a receivable have failed, the receivable is
written off against the allowance. Based on available information, we believe
our allowance for doubtful accounts as of June 30, 2005 is adequate.

      Warranty Obligation. We engage in extensive product quality programs and
processes, including actively monitoring and evaluating the quality of our
component suppliers. In addition to these proactive measures, we also provide
for the estimated cost of product warranties at the time revenue is recognized,
based on historical warranty rates.

      Excess and Obsolete Inventory. Inventories are valued at the lower cost
(first-in, first-out) or market. We maintain reserves for our estimated obsolete
inventory based on historical cost.


                                       52


      Deferred Income Taxes. Deferred income taxes are provided on temporary
differences that arise in the recording of transactions for financial and tax
reporting purposes and result in deferred tax assets and liabilities. Deferred
tax assets are reduced by an appropriate valuation allowance if, in our
judgment, it is more likely than not that the deferred tax asset will not be
realized.

      Valuation of Long-Lived and Intangible Assets. We assess the impairment of
identifiable intangibles and long-lived assets on an annual basis and whenever
events or changes in circumstances indicate that the carrying value may not be
recoverable. When we determine that the carrying value of intangibles and
long-lived assets may not be recoverable, we measure any impairment based on a
projected discounted cash flow method using a discount rate determined by our
management to be commensurate with the risk inherent in our current business
model. If cash generated in the future by the acquired asset is different from
current estimates, or if the appropriate discount rate were to change, then the
net present value of the asset would be impacted, resulting in a charge to
earnings.


      Equity Transactions. In many of our financing transactions, we have issued
warrants. Additionally, we issue options and warrants to non-employees from time
to time as payment for services. In all of these cases, we apply the principles
of SFAS No. 123 "Accounting for Stock-based Compensation" to value these awards,
which inherently include a number of estimates and assumptions including stock
price volatility factors. In addition to interest expense, the Company records
financing and certain offering costs associated with its capital raising efforts
in its statements of operations. These include amortization of debt issue costs
such as cash, warrants and other securities issued to finders and placement
agents, and amortization of debt discount created by in-the-money conversion
features on convertible debt accounted for in accordance with Emerging Issues
Task Force ("EITF") Issue 98-5, "Accounting for Convertible Securities with
Beneficial Conversion Features or Contingently Adjustable Conversion Ratios,"
and Issue 00-27, "Application of Issue 98-5 to Certain Convertible Instruments,"
by other securities issued in connection with debt as a result of allocating the
proceeds amongst the securities in accordance with Accounting Principles Board
("APB") Opinion No. 14, "Accounting for Convertible Debt and Debt Issued with
Stock Purchase Warrants", based on their relative fair values. We based our
estimates and assumptions on the best information available at the time of
valuation, however, changes in these estimates and assumptions could have a
material effect on the valuation of the underlying instruments.


RECENT ACCOUNTING PRONOUNCEMENTS

In December 2004, the FASB revised SFAS No. 123, Share Based Payment, or SFAS
No. 123R. SFAS No. 123R supersedes APB Opinion No. 25, Accounting for Stock
Issued to Employees, and amends Statement No. 95, Statement of Cash Flows. Under
SFAS No. 123R, companies must calculate and record in the income statement the
cost of equity instruments, such as stock options, awarded to employees for
services received. The cost of the equity instruments is to be measured based on
the fair value of the instruments on the date they are granted and is required
to be recognized over the period during which the employees are required to
provide services in exchange for the equity instruments. SFAS No. 123R has been
deferred and is now effective for the Company in the first fiscal year beginning
after December 15, 2005.

The adoption of SFAS No. 123R is expected to have a significant impact on the
Company's financial statements. The impact of adopting SFAS No. 123R cannot be
accurately estimated at this time, as it will depend on the market value and the
amount of share-based awards granted in future periods.

In March 2005, the SEC issued Staff Accounting Bulletin ("SAB") No. 107 ("SAB
107"). SAB 107 provides guidance for the implementation of SFAS 123R with
respect to valuation techniques, expected volatility and expected term for
valuing employee stock options among other matters. The provisions of SAB 107
will be effective for the Company at the time the Company adopts SFAS 123R.

                EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES


Our principal executive officer and its principal financial officer have carried
out an evaluation of the effectiveness of our disclosure controls and procedures
(as defined in Rules 13a -15e and 15d-15(e) under the Securities Exchange Act of
1934) as of September 30, 2005 and have concluded that, as of such date, our
disclosure controls and procedures in place are operating effectively to ensure
material information and other information requiring disclosure is identified
and communicated on a timely basis.


              CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING


During the nine months ended September 30, 2005, there have been no significant
changes in our internal control over financial reporting that have materially
affected or are reasonably likely to materially affect our internal control over
financial reporting.


                CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON
                       ACCOUNTING AND FINANCIAL DISLOSURE

None.

                             DESCRIPTION OF PROPERTY

We own no real property. We occupy 20,500 square feet of office, manufacturing,
and research and development space in Cambridge, UK under a 25 year lease
expiring in April 2024. We do, however, have the option to terminate the lease
agreement at the end of 15 years and again at the end of 20 years. If we choose
not to exercise either of these termination options, the lease will continue
through 2024. We have sublet a portion of this space.

We also occupy approximately 3,700 square feet of office and distribution space
in Andover, Massachusetts under a lease that was schedule to expire in June
2004. On March 5, 2004, we extended this lease for a period of 1 year until June
2005. On March 14, 2005, we extended the expiration date of this lease to April
14, 2008 and expanded our leased space by approximately 2,600 square feet. We
believe that these facilities are in good condition and are suitable and
adequate for its current operations.


                                       53


                              RELATED TRANSACTIONS

During the past two years, we have entered into transactions with various
related parties. These transactions were completed to finance our operations and
to implement our business plans. We believe that each of these transactions were
on terms as favorable to it as the terms we could have obtained from independent
third parties. Specifically, this section discusses transactions entered into
between December 22, 2002 and September 30, 2005 between us and the following
persons:

      - Samuel Belzberg, a former director and his affiliates, Gibralt Capital
Corp. and Gibralt U.S., Inc., a beneficial holder of more than 5% of our common
stock;

      - ProMed Partners, L.P. (and affiliates), a beneficial holder of more than
5% of our capital stock; and

      - Omicron Master Trust, a beneficial holder of more than 5% of our capital
stock.

                     PARTICIPATION BY RELATED PARTIES IN THE
                 SEPTEMBER 30, 2005 PRIVATE PLACEMENT FINANCING

Among the investors in the financing transaction that we completed on September
30, 2005 are ProMed Partners, L.P., ProMed Partners II, L.P., ProMed Offshore
Fund, Ltd. and ProMed Offshore Fund II, L.P. Prior to the September 30, 2005
financing, these entities collectively beneficially owned excess of 5% of our
outstanding common stock. These entities collectively invested a total of $2
million in our September 30, 2005 financing transaction, and accordingly, we
issued an aggregate of 800,000 shares of preferred stock and warrants to
purchase up to 320,000 shares of common stock to these entities. The ProMed
entities participated in the September 30, 2005 financing transaction on
identical terms as the other investors in that financing.

One of our private placement agents in the September 30, 2005 financing, Musket
Research Associates, Inc., is a related party to the ProMed entities.
Specifically, Mr. David Musket is the president of Musket Research Associates
and he also has investment and voting control over the shares of our common
stock beneficially owned by the ProMed entities. With the prior approval of our
board of directors, we entered into a written placement agency agreement with
Musket Research Associates. Pursuant to that agreement, Musket Research
Associates raised $7 million in gross proceeds in the September 30, 2005
financing (including the $2 million invested by the ProMed entities), and we
paid Musket Research Associates commissions of $350,000 for its services in
connection with the September 30, 2005 financing. The rate of commission paid to
Musket Research Associates is the same rate as that we paid to our other private
placement agent in the September 30, 2005 financing, Roth Capital Partners, LLC,
which is not a related party. Roth Capital raised $3 million in gross proceeds
and accordingly we paid $150,000 in placement agent fees to Roth Capital. Our
board of directors determined that our agreement with Musket Research to be on
fair terms, as if it had been negotiated at arms-length with an unrelated party.

Among the holders of convertible debentures we issued in October 2004 to
investors who participated in a financing that we entered into on September 28,
2004 is Omicron Master Trust. As a result of the securities it acquired in that
transaction, Omicron became the beneficial holder of in excess of 5% of our
common stock. The terms of the debentures we issued to Omicron and the two other
debt investors in the 2004 private placement include negative covenants that
were implicated by the proposed financing that we ultimately completed on
September 30, 2005. As an inducement to, and in consideration for, the waiver of
these negative covenants, we issued common stock purchase warrants to Omicron
and the other debenture holders for the purchase of 200,000 shares of common
stock, on a pro rata basis, according to the principal amount of debentures
held. Of these, we issued 119,181 warrants to Omicron. Our board of directors
determined that the issuance of these warrants was fair consideration for the
waiver of rights by the debenture holders as if the same had been negotiated at
arms-length with unrelated parties.

                    PARTICIPATION BY RELATED PARTIES IN THE
     INTERIM FINANCING TRANSACTIONS FROM DECEMBER 2002 TO DECEMBER 31, 2003

          (Figures throughout this section for number of common stock,
   price per share of common stock, options and warrants are adjusted to give
        effect to the 1:25 reverse stock split effective June 17, 2004)

At the beginning of 2003, the board elected a new president and chief executive
officer and three new members of the board. In January 2003, Geoffrey Jenkins,
one of our directors since 2001, became the chairman of the board. Also in
January 2003, James A. Wylie, Jr. became our president and chief executive
officer and a director. Mr. Wylie had been engaged on a consulting basis at the
end of 2002 to review our business operations and viability. In March 2003, Gary
Brooks, a nationally recognized turnaround consultant and crisis manager, and
David Swank, an experienced financial executive with significant accounting and
financial control experience, became independent directors.

In connection with the changes in the Board's composition and our leadership, we
entered into three financing transactions, each of which was with a related
party. Highlights of these three transactions are as follows:


                                       54


      - December 2002 Interim Financing. At the end of December 2002, we
borrowed $2,000,000 from Gibralt U.S. in the form of one-year Class A Secured
Convertible Notes and Class B Unsecured Convertible Notes. In connection with
this loan, we also issued warrants to purchase 333,334 shares of common stock at
an exercise price of $6.50 per share. These funds were used to provide working
capital while new management and new independent directors completed their
assessments of our prospects and operations.

      - May 2003 Interim Financing. In April 2003, we secured loan commitments
for up to $1,200,000 as interim financing from Gibralt U.S. and two directors.
Gibralt U.S. committed to lend up to $1,100,000, and Mr. Wylie and Peter Norris
committed to lend the remaining $100,000 in exchange for one-year Class D
Secured Notes. This transaction closed on May 7, 2003. These funds were used to
provide working capital for us while we pursued our plan to raise long-term
equity financing. We issued preferred shares convertible into a total of 120,863
shares of common stock to these lenders in connection with their loan
commitments.

      - May 2003 Exchange Transaction. Simultaneously with obtaining the
$1,200,000 of loan commitments, we modified several terms and conditions of the
Class A and Class B Notes that we believed might impede the completion of a
permanent equity financing with institutions and accredited investors. First, we
issued Class C Stock, which was convertible into 1,084,690 shares of common
stock, in exchange for the redelivery to us of 333,334 warrants and modification
of the Class A and Class B Notes to make them non-convertible. Second, we issued
Class D Stock, which was convertible into 120,863 shares of common stock, as a
discount for the $1,200,000 in committed secured bridge loans. The 1,205,552
shares of common stock underlying the Class C Stock and Class D Stock
represented in the aggregate approximately 50.36% of our common stock and common
stock equivalents outstanding after the transactions.

      - May 2003 Modification Transaction. On May 28, 2003, we and the holders
of the Class A and Class B Convertible Notes made further modifications to the
notes to accommodate the plan for permanent equity financing. We did not issue
any additional shares or pay any amounts to obtain these changes.

      - August 2003 Exchange of Preferred Shares. As part of our settlement of
the Augenbaum lawsuit, we exchanged the convertible preferred stock we issued on
May 7, 2003 for an equal number of shares of new classes of preferred stock. The
new classes of preferred stock were not by their terms convertible into common
stock, but under a written agreement with the stockholders, these shares were to
be exchanged for an equal number of shares of common stock into which the number
the former classes of common stock were convertible. This exchange was made to
address a claim in the Augenbaum complaint that the preferred stock we issued in
May 2003 could not be convertible by its terms. The plaintiff in Augenbaum
agreed that we could issue the same number of shares of common stock into which
the May 2003 preferred stock would have been convertible, but that the mechanism
should be through an exchange of preferred stock for common stock, not a
conversion of the preferred stock into common stock. Accordingly, the August
2003 exchange agreements with the holders of the preferred stock provide that
after our stockholders approve the issuance of the underlying shares of common
stock, then either we or the holders of the preferred stock may request the
exchange of the preferred stock for that number of shares of common stock into
which the May 2003 preferred stock was convertible.

      - Repayment of $2,000,000 Debt Incurred in December 2002 Interim
Financing. On September 3, 2003, we repaid all of the $2,000,000 in principal
and accrued interest on the notes we issued in connection with the December 2002
interim financing, using a portion of the $6,500,000 gross proceeds of the sale
of Secured Bridge Notes in the equity financing.

      - Conversion of $1,200,000 Debt Incurred in May 2003 Interim Financing. On
November 25, 2003, the $1,200,000 in notes that we issued in our May 2003
interim financing, including accrued interest, converted into common stock at
$2.50 per share. Accordingly, we issued 499,294 shares of common stock to these
noteholders.

           DESCRIPTION OF DECEMBER 2002 INTERIM FINANCING TRANSACTION

The principal terms of the $2,000,000 bridge financing that we completed on
December 27, 2002 were:

      - We borrowed $2,000,000 from Gibralt U.S., whose principal, Samuel
Belzberg, was a member of our board of directors until February 2004.

      - To evidence the loan, we issued $1,000,000 in Class A Notes that were
secured and $1,000,000 in Class B Notes that were unsecured.


                                       57


      - The maturity date of the notes was January 1, 2004.

      - The notes bore interest at 8% per annum, and accrued interest was
payable at maturity.

      - The Class A and the Class B Notes, including principal and accrued
interest, were convertible into common stock at 80% of the common stock price
determined as follows: (i) if we were to complete a financing transaction in
which we issued common stock or common stock equivalents, the price per share of
common stock or common stock equivalent (the weighted average if multiple
financing transactions occur in a rolling 30-day period), (ii) if we were to
complete a financing transaction in which we did not issue common stock or
common stock equivalents, the lower of the average of the closing price of the
common stock for the 15 business days preceding the public announcement of the
financing transaction or the average of the closing price of the common stock
for the 15 business days following the public announcement of the financing
transaction, (iii) if a liquidity event were to occur in which any person or
group other than a stockholder on December 27, 2002 becomes the beneficial owner
of at least 51% of voting control over us, the price per share allocated to each
share of common stock or common stock equivalent, or (iv) if any other liquidity
event were to occur, the lower of the average of the closing price of the common
stock for the 15 business days preceding the public announcement of the
liquidity event or the average of the closing price of the common stock for the
15 business days following the public announcement of the liquidity event.

      - If a merger or reorganization were to occur, the Class A and Class B
Notes were convertible into the kind and number of shares of common stock, other
securities or property into which the notes would have been converted into if
the notes had been converted into common stock on the business day preceding the
merger or reorganization.

      - We agreed not to consummate any financing transaction until January 1,
2004 while any Class A or Class B Notes were outstanding unless we had first
received the approval of the holders of at least 66-2/3% of the outstanding
principal amount of the notes.

      - We also issued to the noteholder warrants to purchase up to 333,334
shares of common stock. The warrants were exercisable for a period of five
years, beginning June 27, 2003, at an exercise price of $6.50 per share, which
was 110% of the market price of the common stock on December 26, 2002. If we,
during the life of the warrants, were to issue common stock or common stock
equivalents at a price per share less than $6.50, the number of warrants would
be increased and the exercise price of the warrants would be decreased to the
lower price per share. If a merger or reorganization were to occur, the warrants
would become convertible into the kind and number of shares of common stock,
other securities or property into which the common stock, other securities or
property issuable upon exercise of the warrants would have been converted if the
warrants had been exercised prior to the merger or reorganization.

      - We and the noteholder entered into an agreement for the registration of
the shares of common stock issuable upon the conversion of the notes and upon
the exercise of the warrants. Under that agreement, we agreed to notify the
noteholder if we were to propose to file certain future registration statements.
We agreed to use our best efforts to register any shares of common stock
issuable to the noteholder in the registration statement, subject to certain
defined limitations, if so requested by the noteholder within 30 days of receipt
of our notice. The noteholder agreed to become subject to a "holdback period,"
by which the noteholder could not effect a public sale of common stock for a
period of up to 180 days following the effective date of the registration
statement, if so requested by a managing underwriter of the offering.

      - The notes and the warrants, pro rata to the notes, were transferable in
part or in whole by the noteholder to one or more third parties, in accordance
with all of the same terms agreed to by the noteholder.

On March 18, 2003, Gibralt U.S. sold and transferred to three investors in a
private transaction (i) $500,000 aggregate principal amount of the notes
($250,000 of which were Class A Notes and $250,000 of which were Class B Notes),
and (ii) 83,334 warrants. None of these transferees was an affiliate of Gibralt
U.S., although one of them is Morris Belzberg, a cousin of Samuel Belzberg.
Samuel Belzberg does not beneficially own, or have investment discretion over,
the securities purchased from him by Morris Belzberg. Accordingly, after this
transfer, Mr. Belzberg beneficially owned 250,000 warrants and $1,500,000
aggregate principal amount of notes ($750,000 of which are Class A Notes and
$750,000 of which are Class B Notes).

                 DESCRIPTION OF MAY 7, 2003 EXCHANGE TRANSACTION

During the first quarter of 2003, our board of directors and management
determined that we should seek permanent financing and continue our efforts to
achieve our business plan. Accordingly, the board of directors approved a plan
to raise long-term equity financing.


                                       58


To address certain issues presented by our capital structure, the board of
directors created a special committee comprised of independent directors, (the
"Independent Committee"). The Independent Committee is comprised of Messrs.
Jenkins, Swank and Brooks. Based on information provided by Mr. Wylie and an
investment banker engaged by us in April 2003, the Independent Committee found
that under prevailing market conditions in the second quarter of 2003,
prospective investors were likely to be reluctant to invest in us because of
certain features of the December 2002 Interim Financing. Specifically, the
Independent Committee found that the future dilution represented by the 333,334
warrants to purchase our common stock and the potential conversion of the
$2,000,000 principal amount of the Class A and Class B Notes were unlikely to be
acceptable to new investors. In addition, the Independent Committee found that
the December 2002 noteholders' right to participate in any future financing at a
20% discount to the price that new investors would be paying and their right to
approve future financing were likely to be obstacles to a completed financing.
The Independent Committee also determined that issuing additional shares in
exchange for modifications to the notes issued in the December 2002 Interim
Financing was, from the perspective of our stockholders, preferable to the
alternative of ceasing operations due to our inability to raise additional
funding.

The Independent Committee began negotiations in April 2003 to modify the terms
of the December 2002 Interim Financing to eliminate the potential obstacles to
obtaining permanent financing. The Independent Committee and the December 2002
noteholders agreed to the proposed terms of the exchange transaction on April
22, 2003 and the transaction closed on May 7, 2003. The principal terms of the
May 7, 2003 exchange transaction were:

      - the noteholders delivered the 333,334 warrants held by them;

      - the noteholders returned the Class A secured notes and Class B unsecured
notes held by them to us for cancellation;

      - to compensate the December 2002 noteholders for surrendering the
conversion rights under the notes and the warrants, we issued a total of 20
shares of Class C Stock (the "Class C Stock") to the December 2002 noteholders,
which were convertible into an aggregate of 1,084,690 shares of common stock;

      - we issued Class C secured notes to the noteholders in principal amounts
equal to the Class A and Class B notes that were cancelled (the "Class C
Notes");

      - the Class C Notes were redeemable for cash at the holder's option if we
were to complete our anticipated permanent financing;

      - the Class C Notes were not convertible into capital stock;

      - the noteholders surrendered their rights to approve future financing
transactions;

      - the Class C Notes were secured by a security interest in our property
identical to the security interest created in the December 2002 Interim
Financing, and otherwise had terms substantially similar to the Class A Notes;
and

      - we expanded our obligation under the registration rights agreement
entered into in December 2002 by granting demand registration rights to the
noteholders regarding the underlying shares of stock.

We also agreed to unwind the May 2003 Exchange Transaction and restore the
original terms of the December 2002 Interim Financing if: (1) our stockholders
did not approve the issuance of the common stock underlying the capital stock
issued to the noteholders in the May 2003 Exchange Transaction, or (2) if we did
not complete our contemplated financing transaction by June 30, 2003 (this date
was subsequently extended to July 31, 2003 under the modifications which were
agreed to on May 28, 2003 and again to November 15, 2003 or any later day that
is one business day following the date agreed by us and the investors for the
second closing of the equity financing).

If the May 2003 Exchange Transaction had been rescinded, then the original terms
of the December 2002 Interim Financing would have been reinstated (except that
all of the notes will be secured). The original terms of the December 2002 notes
provided for conversion of the notes at a variable conversion rate. The original
terms of the Class A and Class B Notes provided for conversion at the
noteholder's option of principal and accrued interest into common stock at a
conversion price equal to 80% of the common stock price, with the common stock
price being determined at the time of conversion. In addition, if the May 7,
2003 exchange transaction had been rescinded, we would have been required to
redeliver the warrants to purchase 333,334 shares of common stock to the
December 2002 noteholders.

To allow for the issuance of the preferred shares associated with the exchange
transaction, on May 5, 2003, we created a new class of preferred stock,
consisting of 20 shares of preferred stock designated as "Class C Stock," each
share of which was to automatically convert into 54,235 shares of common stock
at the time when our stockholders approve the issuance of common stock
underlying the Class C Stock. This would have resulted in an additional
1,084,690 shares of common stock being issued and outstanding after the
conversion occurs. Under the terms of the Class C Stock, the holders of the
Class C Stock held the right to vote that number of shares into which the Class
C Stock is convertible, voting as one class with the holders of common stock and
other capital stock convertible into common stock.


                                       59


In the May 7, 2003 exchange transaction, Gibralt U.S. and the three other
securityholders received (1) Class C Notes in the principal amount equal to the
aggregate principal amount of the Class A and Class B Notes surrendered by them
and (2) shares of Class C Stock, all in exchange for surrendering the conversion
rights of the Class A and Class B Notes (Class C Stock convertible into a total
of 723,714 shares of common stock, or, approximately 36,186 shares of common
stock per $100,000 principal amount of notes exchanged for non-convertible
notes) and the warrants (Class C Stock, convertible into a total of 360,976
shares of common stock, or, approximately 4,332 shares of common stock per 4,000
warrants surrendered). On April 22, 2003, the effective date of the May 7, 2003
exchange transaction, the closing price of the common stock on the AMEX was
$4.00 per share.

The number of shares of Class C Stock issued in the exchange transaction and the
value of the Class C Stock issued to the December 2002 securityholders in the
exchange transaction, using the closing price of the common stock of $4.00 on
April 22, 2003, is as follows:

After the May 2003 Exchange Transaction and Interim Financing were completed and
in light of discussions with our investment banker, the Independent Committee
determined that further modifications to the terms of the securities issued in
the May 2003 transactions would be necessary to assist us in completing the
permanent financing. The material terms of these modifications are described
under "Description of May 2003 Modifications to May 7, 2003 Exchange Transaction
and Interim Financing."


                                       60


              DESCRIPTION OF MAY 2003 INTERIM FINANCING TRANSACTION

In March 2003, the board of directors also determined that we had an immediate
need for capital to support our operations until we completed the contemplated
permanent financing. In April 2003, the board of directors approved a plan to
raise up to $1,200,000 of interim financing prior to May 15, 2003. The board
further determined that, because of our history of operating losses and cash
position at the time, the contemplated permanent financing was likely to involve
the issuance of substantial amounts of equity.

The Independent Committee negotiated with Samuel Belzberg, a principal investor
and a former director, to obtain the needed $1,200,000 interim financing. Mr.
Belzberg committed to lend (through his affiliate, Gibralt U.S.) up to
$1,100,000 to us, and two other directors, James A. Wylie, Jr. and Peter Norris,
each agreed to lend $50,000 to us, to demonstrate their commitment to and
support of us. The board did not believe there were other prospective investors
available to us to provide the interim financing on terms and within a time
period acceptable to us. The Independent Committee and these directors agreed to
the proposed terms of the interim financing on April 22, 2003, and the
transaction closed on May 7, 2003.

The material terms of the May 7, 2003 interim financing transaction are as
follows:

      - Gibralt U.S. committed to lend up to $1,100,000 to us ($1,000,000 of
which was to be funded according to a predetermined funding schedule and the
other $100,000 of which was to be funded upon completion of a certain third
party transaction), and Messrs. Wylie and Norris loaned $50,000 to us. Gibralt
U.S. funded all of its commitment.

      - We issued Class D secured notes in a principal amount equal to the
amount loaned to us (secured on an equal basis with the indebtedness incurred in
the December 2002 Interim Financing and having substantially similar terms as
the Class C notes issued in the May 7, 2003 exchange transaction, except that
they would mature one year from the date of issuance).

      - To compensate the lenders for the risk attendant to their investment and
based on our financial condition, need for additional funding and lack of
definitive terms for a future permanent financing or commitment from any
investor to provide such permanent financing, we issued shares of capital stock
equal to 20% of the amount of the loan commitment of the interim financing
lenders (or, $240,000), in the form of a total of 24 shares of Class D
Convertible Preferred Stock, which were convertible into an aggregate of 120,863
shares of common stock.

      - The Class D noteholders held rights (but not the obligation) to redeem
their notes for the securities issued by us in the permanent financing on the
same terms and conditions as the investors in the permanent financing.

      - The Class D noteholders held rights to redeem their notes for cash if we
consummated our permanent financing.

      - The Class D noteholders held registration rights identical to those
granted to the holders of the Class C Notes issued in the May 7, 2003 exchange
transaction.

During the negotiation process, the lenders required that if the contemplated
financing did not occur prior to June 30, 2003 (subsequently extended to July
31, 2003 in the May 28, 2003 modifications, described below and thereafter
extended to November 15, 2003 and again to a day after November 15, 2003 that we
and the investors agreed as the date for the second closing of the equity
financing), then the lenders could accelerate the maturity date of their notes.

We created a new class of preferred stock from our authorized preferred stock,
consisting of 24 shares of preferred stock designated as "Class D Convertible
Preferred Stock," each share of which would have been automatically converted
into 5,036 shares of common stock when our stockholders approved the issuance of
these shares of common stock underlying the Class D Convertible Preferred Stock.
This would have resulted in an additional 120,863 shares of common stock being
issued and outstanding after the conversion occurs. Under the terms of the Class
D Stock, the holders of the Class D Stock had the right to vote that number of
shares into which the Class D Stock was convertible, voting as one class with
the holders of common stock and other capital stock convertible into common
stock.

The loan commitments of the lenders in the May 7, 2003 interim financing and the
principal amount of Class D Notes, the number of shares of Class D Convertible
Preferred Stock (and the number of shares of common stock into which the Class D
Stock is convertible) the lenders received, as well as the value of the Class C
Stock issued to the lenders in the interim financing using the closing price of
the common stock of $4.00 on April 22, 2003, and after giving effect to the
issuance of the shares to be issued upon conversion of the Class C Stock and the
Class D Stock, is as follows:

Gibralt U.S., Mr. Norris and Mr. Wylie loaned a total of $1,200,000 to us,
representing their entire loan commitments.

                    DESCRIPTION OF MAY 28, 2003 MODIFICATIONS
                       TO MAY 7, 2003 EXCHANGE TRANSACTION
                              AND INTERIM FINANCING

As we proceeded to seek our permanent financing during May 2003, we assessed the
availability of investment capital for development stage companies. The
Independent Committee determined that it was essential to extend the maturity
date of the Class C Notes beyond January 1, 2004, to eliminate the right of the
holders of the Class C Notes to redeem those notes for cash upon the completion
of the future permanent financing and to limit in certain respects the
collateral securing our obligations under the Class C and Class D Notes. The
Independent Committee determined that these modifications were necessary because
the terms of the Class C and Class D Notes would likely, unless modified, deter
investors from investing in us. The Independent Committee found that prospective
investors would presumably expect that we would use the proceeds of their
investment as working capital rather than apply the proceeds to the satisfaction
of existing debt. Accordingly, the Independent Committee negotiated further
modifications to the May 7, 2003 exchange transaction, as well as modifications
to the May 2003 interim financing transaction, as described below in this
section.

The Independent Committee determined that the maturity date of the Class C Notes
should be extended to January 1, 2006. In addition, the Independent Committee
determined that the security interest granted to the Class C noteholders should
be limited to certain collateral that was owned at December 31, 2002 and that
the note collateral should not include our after-acquired property, thereby
making that property available as security to our future investors. The
Independent Committee further determined that the Class D Notes should not be
redeemable for cash upon the closing of the future financing transaction.
Instead, the Class D Notes should be converted into the securities issued in the
future financing on the same terms and conditions offered to the other
investors. With these objectives, the Independent Committee commenced
negotiations with the holders of the Class C Notes and the Class D Notes.

The Class C noteholders required that, in exchange for the modifications we
sought, the terms of their notes be revised to increase the interest rate from
8% to 12.5% per annum, and to require that we commence making payments of
interest accrued from December 27, 2002 through May 27, 2003 and principal on a
quarterly basis beginning the first quarter of 2004, but only to the extent of
50% of our excess quarterly cash flow.

The Class C noteholders also agreed to modify the security for the notes, the
change to become effective when we raised at least $6,000,000 in our permanent
financing. The Class C noteholders agreed that their security interest in
accounts receivable would be subordinated to a future security interest granted
by us in a receivables financing transaction and that their security interest in
intellectual property would be limited to that owned as of December 31, 2002.


                                       62


The Class C noteholders required that we maintain minimum inventory and fixed
asset levels, determined quarterly, of not less than $2,000,000. In addition,
our combined cash, inventory and fixed assets must be at least $3,271,400. A
failure to comply with these covenants is an event of default. The notes have
other events of default for matters such as non-payment of interest or
principal, breach of representations and warranties, failure to satisfy any
agreement or condition under the agreements with the investor which is not cured
within 30 days, a "cross-default" for our other institutional indebtedness and
our voluntary or judicial dissolution or bankruptcy. We and the Class C
noteholders exchanged the Class C Notes for an equal principal amount of Class E
Notes with these modified terms.

The covenant relating to minimum inventory, net book assets and cash levels does
not apply unless and until we raise at least $6,000,000 in gross proceeds in a
future financing. We did not expect an event of default relating to this
requirement to occur if we completed our contemplated permanent financing. No
events of default occurred. If any event of default occurred and was not cured
within the applicable cure period, then, unless the default was waived by a
majority in interest of the noteholders, at the option and in the discretion of
the holders of at least 66 2/3% of the principal amount of the Class E Notes,
the noteholders could have declared the notes and all accrued interest to be
immediately due and payable, and could have immediately enforced any and all of
the noteholder's rights and remedies provided in the agreements with and the
investors and any other rights or remedies afforded by law.

The Class D noteholders agreed to redeem their Class D Notes in exchange for the
securities issued in the contemplated permanent financing on the same terms and
conditions offered to the other investors and to forego the option of redeeming
their notes for cash after the permanent financing occurred.

The noteholders also agreed to extend the date by which we would be required to
raise $6,000,000 in our permanent financing (to avoid triggering the December
2002 securityholders' right to rescind the May 7, 2003 exchange transaction)
from June 30, 2003 to July 31, 2003 (and subsequently, to November 15, 2003 and
again to a day after November 15, 2003 that we and the investors agree as the
date for the second closing of the of the equity financing), and to defer our
obligation to seek stockholder approval of the conversion of the Class C Stock
and Class D Stock into shares of common stock until a future meeting of the
stockholders, at which we would also seek approval of the issuance of common
stock underlying securities that may be issued by it in the permanent financing.
The rescission right was not available unless the meeting was held and the
issuance was not approved.

On September 3, 2003, we redeemed all of our outstanding Class E Notes
(principal of $2,000,000 plus accrued interest of approximately $132,000), and
no Class E Notes remain outstanding. We used a portion of the proceeds of the
first closing of the equity financing to pay for the redemption of the Class E
Notes.

           AUGUST 2003 AND NOVEMBER 2003 EXCHANGES OF PREFERRED SHARES

As a result of the stipulation of settlement that we reached in the Augenbaum
litigation, we entered into exchange agreements with the holders of the
outstanding shares of our Class C Stock and Class D Convertible Preferred Stock.
Upon entering into the exchange agreements, on August 22, 2003 the holders of
the Class C Stock exchanged their Class C Stock for 20 Class E Shares, on a
share-for-share basis. Similarly, upon execution of the exchange agreements, the
holders of the 24 outstanding Class D Stock exchanged their Class D Stock for
Class F Shares, on a share-for-share basis. Following these exchanges, we
eliminated all Class C Stock and all Class D Stock.

Shares of the Class E Stock are preferred in liquidation to the extent that,
before any distribution of assets can be made to the holders of our common
stock, there will be distributed pro rata to the holders of the issued and
outstanding Class E Shares and Class F Shares the amount of $108,469 as to each
outstanding Class E Share and $10,072 per share as to each outstanding Class F
Share. The holders of the common stock then share in the remainder of net
liquidation of proceeds. The term liquidation means our liquidation, dissolution
or winding up, as well as any sale, lease, exchange or other disposition of all
or substantially all of our assets. The aggregate liquidation preference of the
Class E Shares is $2,169,380 and the aggregate liquidation preference of the
Class F Shares is $241,728. The aggregate liquidation preference was determined
to be equal to the dollar value that the board of directors allocated to the
conversion rights, warrants and other rights that we agreed to pay to the
holders of the Class C Stock and the discount that we agreed to pay to the
holders of the Class D Stock in the May 7, 2003, transactions.

The holders of the Class E Shares and Class F Shares have the right to vote one
vote per share, respectively, for each outstanding Class E Share and each
outstanding Class F Share.

The holders of the Class E Shares are entitled to cash dividends and
distributions when and as declared by the board of directors, pari passu with
the holders of our common stock with the dividend amount on each Class E Share
being 1,355,862 times the dividend or distribution to be paid on each share of
common stock. The holders of the Class F Shares are entitled to cash dividends
and distributions when and as declared by the board of directors, pari passu
with the holders of our common stock with the dividend amount on each Class F
Share being 125,898 times the dividend or distribution to be paid on each share
of common stock.


                                       63


The exchange agreements also gave both us and the holders of the Class E Shares
and the Class F Shares rights to exchange those preferred shares for shares of
our common stock, as long as our stockholders approve the issuance of the shares
of our common stock underlying the preferred shares and the AMEX approves the
listing of these shares of common Stock. Specifically, if the stockholders
approve the common stock issuance and the AMEX lists these the shares of common
stock, then the holders of the Class E Share have the right to sell to us, and
we have the right to purchase from them, each outstanding Class E Share in
exchange for 54,235 shares of our common stock per Class E Share. Similarly, the
holders of the Class F Shares have the right to sell to us, and we have the
right to purchase from them, each outstanding Class F Share in exchange for
5,036 shares of our common stock per Class F Share. The exchange agreements also
provided that, should any sale, lease, exchange or other disposition of all or
substantially all of our assets occur while the Class E Shares and the Class F
Shares are outstanding, each holder of the Class E Shares has the right to sell
to us all Class E Shares in exchange for 54,235 shares of common stock per Class
E Share. Similarly, each holder of Class F Share has the right to sell to us all
Class F Shares in exchange for 5,036 shares of common stock per Class F Share.

The board of directors determined that the terms of the exchange agreements were
appropriate in order to provide the former holders of the Class C Stock and the
Class D Stock with the economic equivalence of the conversion rights they held
in conjunction with the Class C Stock and Class D Stock. Upon exchange of all
Class E Shares, the former holders of the Class C Stock will receive 1,084,690
shares of our common stock, or the same number of shares of our common stock we
were obligated to issue to them upon conversion of the Class C Stock. Upon
exchange of all the Class F Shares, the former holders of the Class D Stock will
receive 120,863 shares of common stock, or the same number of shares of our
common stock that we were obligated to issue to them upon conversion of the
Class D Stock. In the stipulation of settlement for the Augenbaum litigation,
the parties agreed on the exchange of shares of our common stock in these
specific amounts for the Class E Shares and Class F Shares, as well as the
exchange of the Class E Shares for the Class C Stock and the exchange of the
Class F Shares for the Class D Stock. A hearing before the Delaware Chancery
Court for approval of the stipulation of settlement was held on September 15,
2003. After this hearing, the court entered an order approving the stipulation
of settlement as submitted. The stipulation of settlement became final on
October 15, 2003 when the appeal period terminated with no appeal having been
filed.

At the request of the investors in our equity financing, we and Gibralt U.S., on
behalf of itself and the other holders of the Class E Shares and Class F Shares,
agreed not to exchange the Class E Shares or Class F Shares for common stock
until the second closing of the equity financing. Gibralt U.S. also acknowledged
that the common stock to be issued upon the exchange of the Class E Shares and
Class F Shares will not be eligible to participate in the offering to
stockholders, and that only those shares of common stock held by Gibralt U.S.
and the other holders of Class E Shares and Class F Shares as of August 29, 2003
will be eligible to participate in the offering.

Pursuant to the August 2003 exchange agreement, in connection with the equity
financing, on November 25, 2003 we exchanged all outstanding shares of Class E
Stock for a total of 1,084,690 shares of common stock and we exchanged all
outstanding shares of Class F Stock for a total of 120,863 shares of common
stock. After these shares were exchanged, we had no shares of preferred stock
outstanding.

     PARTICIPATION BY RELATED PARTIES IN THE SEPTEMBER 2003 EQUITY FINANCING

INVESTMENT BY THE HOLDERS OF THE CLASS E NOTES AT THE FIRST CLOSING. As part of
the negotiation of the equity financing, the investors indicated that, were they
to purchase notes that would be convertible into shares of our common stock, the
notes would be required to be secured by all of our assets, including the patent
rights acquired by us with the proceeds of the first closing and also by those
assets that, prior to the first closing, were encumbered by security interests
in favor of the then-outstanding Class E Notes. As a result, we offered to
Gibralt U.S. and to the other three holders of the Class E Notes the opportunity
to purchase $2,000,000 of the Secured Bridge Notes, which was the outstanding
principal amount of the Class E Notes, and to use part of the proceeds of the
first closing to retire the Class E Notes in full, making the collateral
securing the Class E Notes available to all holders of the Secured Bridge Notes.
The board of directors unanimously, with the abstention of Samuel Belzberg,
approved the terms on which the holders of the Class E Notes would participate
in the equity financing at the first closing. Under those terms, the full
$2,000,000 new investment made by the holders of the Class E Notes would be
allocated to the purchase of Secured Bridge Notes and the holders of the Class E
Notes would, in exchange, terminate the security interest encumbering our assets
and make those assets available as collateral for all holders of the Class E
Notes. The former holders of the Class E Notes received as security for the
repayment of the Secured Bridge Notes held by them, a pro rata interest in the
same collateral securing all of the other Secured Bridge Notes. As is the case
with all Secured Bridge Notes, the Secured Bridge Notes held by Gibralt U.S. and
the other former holders of the Class E Notes converted into common stock on
November 25, 2003 at a purchase price of $2.00 per share.

CONVERSION OF CLASS D NOTES AT FINAL CLOSING. The terms and conditions under
which we issued our outstanding Class D Notes to Gibralt U.S., Peter Norris and
James A. Wylie, Jr. in May 2003 included a requirement that the Class D Notes be
converted into equity on the same terms and conditions on which all other
investors participate in an equity financing. Therefore, on November 25, 2003,
the $1,200,000 principal amount plus accrued interest on the Class D Notes
converted into our common stock at a price of $2.50 per share, and we issued
499,294 shares of common stock to the former holders of the Class D Notes.


                                       64


AGENCY CAPACITY OF GIBRALT U.S. After the first closing of the equity financing,
Gibralt U.S. ceased to act as the "Designated Note Purchaser" on behalf of the
Class E Notes (because these notes were redeemed and are no longer outstanding),
and at the second closing, ceased to act as the "Designated Lender" on behalf of
the holders of the Class D Notes because they are converted at the second
closing. In addition, Gibralt U.S. agreed to act as the "Designated Note
Investor" under the security agreement that provided the security interest to
the Secured Bridge Note holders and as the "Designated Pledgeholder" under the
pledge agreement under which Gibralt U.S. held all outstanding shares of Diomed
PDT, Inc., an indirect wholly-owned subsidiary of us, as security for holders of
the Secured Bridge Notes and the Class E Notes.

On August 21, 2003, Gibralt U.S. also agreed, on behalf of the holders of the
Class E Shares and the Class F Shares, that their right to registration of those
shares of our common stock for which they are exchangeable would be governed by
the registration rights agreement entered into connection with the equity
financing rather than the agreements that had been entered into at the time of
the acquisition of the Class C Stock and the Class D Stock. On August 21, 2003,
Gibralt U.S., acting on behalf of all holders of the Class D Notes, also agreed
that although it had the right to declare the Class D Notes immediately due and
payable , it would extend this deadline to the business day following the second
closing of the equity financing.

 ACCELERATED CONVERSION OF CLASS A CONVERTIBLE PREFERRED STOCK ON MARCH 31, 2003

In March 2003, the board of directors determined to accelerate the conversion
into common stock of all our outstanding shares of Class A Stock, including
those shares owned by related parties, pursuant to the authority reserved in the
board under the terms of Class A Stock. Pursuant to the terms of the Class A
Stock, on December 31, 2002 the Class A Stock had begun to automatically convert
into common stock at the rate of 5% of the aggregate number of shares originally
issued at that date and at the end of each month thereafter, with those shares
that were not converted at the end of February 2004 automatically converting
into common stock on February 29, 2004. The original terms of the Class A Stock
also provided that after February 28, 2003, the board of directors could in its
discretion accelerate the rate of conversion or increase the amount of shares of
Class A Stock being converted, so long as the change applied equally to all
shares of Class A Stock.

The purpose for the conversion feature of the Class A Stock, when the terms of
the Class A Stock were designated in February 2002, was to permit a staggered
increase in the number of shares of common stock available for trading in order
to minimize the market disruption that otherwise may occur if a large block of
shares were to become tradable at once. In March 2003, the board determined that
the effect of the incremental conversion of Class A Stock into common stock
would impair our ability to procure additional equity investment. The board
further determined that due to the apparent negative impact on our ability to
obtain equity financing, the board's goal is to have only one class of capital
stock outstanding prior to completing our permanent financings. Pursuant to our
discretion under the terms of the Class A Stock, the board determined to cause
all of the outstanding shares of Class A Stock to convert into common stock as
of March 31, 2003. This acceleration affected all holders of Class A Stock
equally, whether related parties or non-affiliated parties.

As a result of the board's determination to accelerate the conversion of the
Class A Stock, on March 31, 2003 we converted all 525,715 outstanding shares of
Class A Stock (including 234,554 shares held by related parties) into an equal
number of shares of common stock, resulting in a total of 1,188,470 shares of
common stock outstanding and no Class A Stock outstanding. Those related parties
who owned Class A Stock as of March 31, 2003 immediately prior to the conversion
into common stock and the numbers of shares they held are as follows:

      The benefit derived by those related parties of us who owned Class A Stock
on March 31, 2003 was the conversion of our Class A Stock into common stock.
This was the same as the benefit derived by all other former holders of Class A
Stock as a result of this transaction.

payable in cash or under certain circumstances and at our election, in the form
of common stock. See "Liquidity and Capital Resources; Transactions in 2005 -

    (Figures throughout this section are adjusted to give effect to the 1:25
   reverse stock split effective June 17, 2004 for number of shares of common
          stock, price per share of common stock, options and warrants)

References in the following description are to securities of Diomed Holdings,
Inc. unless otherwise stated or readily indicated by context.

Our authorized capital stock consists of 50,000,000 shares of common stock, par
value $.001 per share, and 20,000,000 shares of preferred stock.

As of September 29, 2005 (before giving effect to our September 30, 2005
financing transaction), there were 19,423,728 shares of common stock
outstanding, plus an additional 6,745,657 shares of common stock represented by
outstanding convertible debentures, warrants and stock options, resulting in
26,169,385 shares of common stock outstanding on a fully diluted basis. There
were zero shares of preferred stock outstanding as of September 29, 2005. As of
September 30, 2005 (after giving effect to the financing transaction that we
completed that day), there were 19,423,728 shares of common stock outstanding,
plus an additional 12,545,657 shares of common stock represented by the
4,000,000 shares of preferred stock and 1,800,000 warrants we issued on
September 30, 2005 and the previously outstanding convertible debentures,
warrants and stock options, resulting in 31,969,385 shares of common stock
outstanding on a fully diluted basis. There were 4,000,000 shares of preferred
stock outstanding as of September 30, 2005.

The following description of our capital stock does not purport to be complete
and is subject to and qualified by our Articles of Incorporation and By-laws,
which are included as exhibits to this report, and by the provisions of
applicable Delaware law.

                                  COMMON STOCK

Subject to preferences that may be applicable to any rights of holders of
outstanding stock having prior rights as to dividends, the holders of
outstanding shares of our common stock are entitled to receive dividends out of
assets legally available therefor at such times and in such amounts as the board
of directors from time to time may determine. Holders of our common stock are
entitled to one vote for each share held on all matters submitted to a vote of
the stockholders. Cumulative voting with respect to the election of directors is
permitted by our Certificate of Incorporation. The common stock is not entitled
to preemptive rights and is not subject to conversion or redemption. Upon our
liquidation, dissolution or winding-up, the assets legally available for
distribution to stockholders are distributable ratably among the holders of the
common stock after payment of liquidation preferences, if any, on any
outstanding stock having prior rights on such distributions and payment of other
claims of creditors. Each share of common stock outstanding as of the date of
this prospectus is validly issued, fully paid and nonassessable.

                                 PREFERRED STOCK

Our board of directors is authorized, subject to any limitations prescribed by
Delaware law, to issue preferred stock. The board of directors can fix the
rights, preferences and privileges of the shares and any qualifications,
limitations or restrictions thereon. The board of directors may authorize the
issuance of preferred stock with voting or other rights that could adversely
affect the voting power or other rights of the holders of common stock. Each
share of preferred stock outstanding as of the date of this prospectus is
validly issued, fully paid and nonassessable.

The issuance of preferred stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes could, among other things,
under certain circumstances, have the effect of delaying, deferring or
preventing a change in control. The issuance of preferred stock may adversely
affect the rights of our common stockholders by, among other things:

      - restricting dividends on common stock;

      - diluting the voting power of the common stock;

      - impairing the liquidation rights of the common stock; or

      - delaying or preventing a change in control without further action by the
stockholders.

Four million shares of preferred stock are currently issued and outstanding,
having been issued pursuant to the private placement financing that we completed
on September 30, 2005. See `Liquidity and Capital Resources", Transactions in
2005 - Private Placement Financing Completed September 30, 2005," above, for a
discussion of the particular rights and preferences designated by the board of
directors for these shares of preferred stock. After giving effect to the
4,200,000 shares designated for issuance in the September 30, 2005 financing (of
which only 4,000,000 were issued and sold), we had an additional 15,800,000
authorized but unissued shares of preferred stock available.

                                  STOCK OPTIONS

In November 2003, our stockholders approved our 2003 Omnibus Incentive Plan,
under which we reserved 1.6 million shares of common stock for future issuance.
In May 2005, our stockholders approved an increase of 1.5 million shares
reserved, providing for a total of 3.1 million shares of common stock reserved
for future issuance. The 2003 Omnibus Plan provides for grants or awards of
stock options, restricted stock awards, restricted stock units, performance
grants, stock awards, and stock appreciation rights. Only present and future
employees and outside directors and consultants are eligible to receive
incentive awards under the 2003 Omnibus Plan. Stock options are currently
outstanding under the 2003 Omnibus Plan and two prior plans, the 1998 Stock
Option Plan and the 2001 Stock Option Plan.

The exercise price and vesting of individual awards granted are determined by
the board of directors at the date of grant. Our current policy provides for
options to generally vest over two to four years and expire 10 years after the
date of grant. Incentive stock options under the plans are granted at not less
than fair market value per share of common stock on the date of grant or 110% of
fair market value for any stockholder who holds more than 10% of the total
combined voting power of all classes of stock of the Company.

As of September 30, 2005, 1,526,818 options and other incentive stock awards
were available for future grants under the 2003 Omnibus Plan. In addition, 2.542
options were available under the 2001 Plan as of September 30, 2005.

As of September 30, 2005, options to purchase a total of 1,711,225 shares of
common stock were issued and outstanding, as follows:

ownership and to provide copies of such reports to us. Based solely on a review
of the copies of such reports furnished to us and written representations that
no other reports were required to be filed during the fiscal year ended December
31, 2004, we believe that all of the filing requirements applicable to our
officers, directors and beneficial owners of greater than 10% of our common
stock were complied with during the most recent fiscal year as to which we have
issued our annual report, except as follows:

Three of our directors and executive officers did not timely file notices of the
acquisition of stock options that we granted during 2004. The following grants
of options were not reported within ten business days of grant to these new
directors on Forms 3 required to be filed with the SEC, but were reported when
these officers and directors filed their respective Forms 5 with the SEC in
February 2005:

In the debt and equity financing that we completed on October 25, 2004, we
issued to Omicron Master Trust (i) convertible debentures in the principal
amount of $5.5 million, convertible into 2,401,747 shares of common stock and
(ii) warrants to purchase 1,439,791 shares of common stock. These securities
represented approximately 20% of our outstanding shares (assuming the conversion
and exercise of Omicron's derivative securities). To our knowledge, Omicron did
not file a Form 3 with the SEC to indicate its acquisition of beneficial
ownership of common stock, required to be filed within 10 business days of the
acquisition of these securities, or Forms 4 to reflect any subsequent
acquisitions or dispositions of our securities that may have occurred.

                              EMPLOYMENT AGREEMENTS

Chief Executive Officer

Effective January 10, 2003, we entered into an employment agreement with James
A. Wylie, Jr. as president and chief executive officer. Mr. Wylie became a
director as of that date. Mr. Wylie's employment agreement was for an initial
term of two years and provided for an annual base salary of $300,000 (payable
commencing March 1, 2003), an award of options to purchase up to 32,000 shares
(figure adjusted for 1:25 reverse stock split effective on June 17, 2004) of
common stock and certain bonus compensation, including a discretionary bonus as
determined by the board of directors and a bonus for the consummation of certain
financings (including the equity financing), mergers or similar transactions. If
we terminated Mr. Wylie's employment other than for cause, we would have been
obligated to pay his salary and provide benefits to him for the remainder of his
two-year employment term. From December 2, 2002 until the effective date of his
employment agreement, Mr. Wylie acted as a consultant to us and an advisory
board member, pursuant to a management services agreement. Under the management
services agreement, we paid Mr. Wylie a consulting fee of $125,000 for the
period December 2, 2002 through February 28, 2003, and agreed to pay a success
fee for the consummation of certain financing, merger or similar transactions
(excluding the December 27, 2002 bridge financing transaction). The management
services agreement was terminated upon the effective date of Mr. Wylie's
employment agreement and was superseded by his employment agreement.

Effective December 28, 2003, we entered into a second employment agreement with
James A. Wylie, Jr. This agreement superseded our January 10, 2003 employment
agreement with Mr. Wylie, and extended his employment by one year from December
31, 2004 until December 31, 2005. Mr. Wylie's new agreement provided for an
annual base salary of $330,000 (commencing January 1, 2004), an award of options
to purchase up to 108,000 shares (figure adjusted for 1:25 reverse stock split
effective on June 17, 2004) of common stock and certain bonus compensation. If
we terminated Mr. Wylie's employment other than for cause, we would have been
obligated to pay his salary and provide benefits to him for the remainder of his
two-year employment term.

Effective February 15, 2005, the terms of Mr. Wylie's employment were modified
by (i) extending the term of employment through December 31, 2007 (formerly, the
term was through December 31, 2005 at an effective annual base salary of
$355,000), (ii) providing that in the event of termination by us without cause
or by Mr. Wylie for good reason, we will pay an amount equal to either his base
compensation for the remainder of the term or 12 months, whichever is greater
and (iii) clarifying that Mr. Wylie will be able to terminate his employment
agreement upon not less than 90 days' notice for reasons other than good reason,
in which case we will not be required to pay severance.

Chief Financial Officer

Effective September 1, 2003, we entered into a consulting agreement with David
B. Swank, as chief financial officer. Mr. Swank's agreement provided for us to
pay him a monthly fee of $12,500, and entitled him to receive options to
purchase shares of common stock and bonus compensation. Effective March 1, 2004,
we increased Mr. Swank's monthly fee to $16,667. Mr. Swank's agreement was for
six-month automatically renewable periods, and was cancelable upon six months
notice. Effective September 1, 2004, Mr. Swank's agreement was automatically
extended for a second six-month period until March 1, 2005, at a monthly fee of
$16,667.

Effective February 15, 2005, we modified the terms of Mr. Swank's employment by
(i) providing a term through December 31, 2005, renewable annually thereafter
unless either party gives notice of non-renewal by November 30, (ii) providing
that we may terminate Mr. Swank's employment for cause upon written notice,
(iii) providing that in the event of termination by us without cause or by Mr.
Swank for good reason, we will pay an amount equal to either his base
compensation for the remainder of the term or 12 months, whichever is greater,
(iv) providing that Mr. Swank will not use or disclose proprietary information
or confidential information, that all proprietary information is our property
and that all inventions of Mr. Swank during the term of his employment that are
related to our business are our property and (v) providing that Mr. Swank will
not compete with us or solicit our customers, suppliers or employees during the
term or for 12 months thereafter.


                                       75


Our executive officers (Messrs. Stearn, Welch, Paulette and Geberth) have
agreements which provide that upon termination of their respective employment
without cause, we will pay their annual base salary for a period of twelve
months. These agreements also provide that these executive officers are eligible
to receive annual bonuses based on performance. These employment agreements also
prohibit our executive officers from directly or indirectly competing with us
for a period of one-year following termination of their employment.

There have been no adjustments or amendments to the exercise price of stock
options for our executive officers or directors, other than adjustments to
then-outstanding stock options that correspond with the 1:25 reverse split
effective June 17, 2004, which decreased the number of option shares and
increased the option exercise price, in each case by a factor of 25.

                               STOCK OPTION PLANS

     (Figures throughout this section for number of common stock, price per
   share of common stock, options and warrants are adjusted to give effect to
            the 1:25 reverse stock split effective on June 17, 2004)

In November 2003, our stockholders approved a new incentive plan, the 2003
Omnibus Plan. The 2003 Omnibus Plan provides for grants or awards of stock
options, restricted stock awards, restricted stock units, performance grants,
stock awards, and stock appreciation rights. Only present and future employees
and outside directors and consultants are eligible to receive incentive awards
under the 2003 Omnibus Plan. We obtained stockholder approval of the 2003
Omnibus Plan at our annual meeting on November 25, 2003, after which we reserved
1.6 million shares of common stock for issuance pursuant to this plan. At our
annual meeting of stockholders held on May 17, 2005, our stockholders approved
an increase of 1.5 million shares providing for a total of 3.1 million shares of
common stock reserved for future issuance. As of June 30, 2005, 1,540,549
options and other incentive stock awards were available for future grants under
the 2003 Omnibus Plan. In addition, 2,542 options were available under the 2001
Plan as of June 30, 2005. No options were available under the 1998 Plan as of
June 30, 2005.

(1) Based on the closing price of $4.32 on the AMEX on December 31, 2004 and the
respective exercise prices of the options held.

No adjustments to the exercise price of any outstanding options were made during
the fiscal year ended December 31, 2004, other than in connection with the 1:25
reverse split effective June 17, 2004, which resulted in a reduction in the
number of option shares by a factor of 25 and a 25 fold increase in the exercise
price of each outstanding option.

               DETERMINATION OF NUMBER OF SHARES TO BE REGISTERED


The shares we are registering pursuant to the registration statement of which
this prospectus is a part relate to the private placement financing that we
completed on September 30, 2005 (see "Liquidity and Capital Resources;
Transactions in 2005 - Private Placement Financing Completed September 30,
2005," above) and consist of the following:

      o     4 million shares of common stock we may issue upon exchange of
            preferred stock that we issued and sold to 18 investors on September
            30, 2005 at an issue price of $2.50 per share;

      o     2.95 million shares of common stock that we may issue in payment of
            dividends on the preferred stock we issued September 30, 2005;

      o     1.6 million shares of common stock that we may issue upon the
            exercise of common stock purchase warrants that we issued to the
            investors who purchased the preferred stock that we sold under the
            September 30, 2005 financing transaction; and

      o     200,000 shares of common stock that we may issue upon the exercise
            of common stock purchase warrants that we issued on September 30,
            2005 to the three holders of outstanding convertible debentures we
            issued and sold on October 25, 2004 as an inducement for them to
            grant to us waivers of certain negative covenants under the
            debentures that they held.

We are registering 125% of the foregoing shares pursuant to our agreement to
register that number of shares under the registration rights agreement that we
entered into in connection with the September 30, 2005 financing transaction.
The registration of an additional allowance of shares will provide for
additional registered shares that we may issue to the Selling Stockholders if we
issue dividends in the form of common stock in excess of the amount allotted, if
antidilution adjustments to the exchange rate of the preferred stock or the
exercise price of the warrants so require or if shares become issuable upon any
stock split dividend or distribution, recapitalization or similar event.

We calculated the number of shares issuable as follows:

In respect of the exchange of preferred stock, we assumed that all 4 million
shares of preferred stock will be exchanged by the holders for an equal number
of shares of common stock, at the existing exchange rate of $2.50 per share.

In respect of the dividends on the preferred stock, we have assumed that (i) all
4 million shares of preferred stock will remain outstanding for five years, (ii)
dividends will accrue for five years, (iii) we will pay all dividends on the
preferred stock in the form of common stock and (iv) the average price per share
of the common stock issued as dividends will be $2.00. Pursuant to this
calculation, dividends accrued over five years will be $900,000 for the first 18
months ($10 million at 6% per annum), $500,000 for the following six months ($10
million at 10% per annum) and $4.5 million for the following three years ($10
million at 15% per annum). Based on these assumptions, aggregate dividends of
$5.9 million will accrue over the five years while the preferred stock is
outstanding, and we will issue 2.95 million shares of common stock as dividends
on the preferred stock. If shares of preferred stock are exchanged for common
stock or are redeemed earlier than five years, then fewer dividends will accrue,
and accordingly, fewer shares of common stock will be issuable as dividends. If
the average price of our common stock for purposes of paying dividends is less
than $2.00 per share, then a larger number of shares of common stock will be
issuable as dividends should we choose to pay dividends in shares rather than in
cash.


                                       82


In respect of the exercise of warrants, we have assumed that all 1.8 million
warrants will be exercised by payment of cash at the current exercise price of
$2.50 per share.

        DILUTION RESULTING FROM SEPTEMBER 30, 2005 FINANCING TRANSACTION

The September 30, 2005 financing transaction was dilutive to the pre-transaction
holders of common stock, in that we issued common stock equivalents in that
financing which have the effect of reducing the pro rata voting and other rights
of the pre-transaction stockholders. Because the actual number of shares of
common stock that will ultimately be issued to the September 2005 investors is
based on future factors that are unknown to us at this time, it is impossible to
specify this amount of dilution. However, we can specify that, at a minimum, 4
million shares of common stock underly the preferred stock (assuming no
dividends are paid in the form of common stock and no antidilution adjustments
are made to the $2.50 exchange rate of the preferred stock), and a minimum of
1.8 million shares of common stock underly the warrants (assuming no
antidilution adjustments are made to the $2.50 exercise price of the warrants or
number of shares that may be purchased upon exercise), and in each case assuming
that the limitations on ownership applicable to the exchange of the preferred
stock and the exercise of the warrants (described under "Liquidity and Capital
Resources; Transactions in 2005 - Private Placement Financing Completed on
September 30, 2005," above) do not apply. This minimum of 5,800,000 shares
represents approximately 22% of the fully diluted common stock outstanding prior
to the September 30, 2005 financing transaction. The issuance of the 10,937,500
underlying shares we estimated for purposes of this registration statement
represents approximately 42% of the fully diluted common stock outstanding prior
to the September 30, 2005 financing transaction.

Prior to the September 30, 2005 financing transaction, we had 19,423,728 shares
of common stock outstanding, plus common stock equivalents (including
convertible debentures, stock options and warrants), representing an additional
6,745,657 shares of common stock. Accordingly, 26,169,385 shares of common stock
were issued and outstanding on a fully diluted basis. Thus, the minimum of 5.8
million shares issuable represents approximately 22% of the 26,169,385 fully
diluted shares pre-transaction, and the registered amount of 10,937,500 shares
represents approximately 42% of the 26,169,385 fully diluted shares
pre-transaction. If we issue only the minimum of 5,800,000 shares of common
stock underlying the preferred stock and warrants that we issued in the
September 30, 2005 financing transaction, 31,969,385 shares of common stock will
be issued and outstanding on a fully diluted basis. If we issue all 10,937,500
shares of common stock that we have estimated for registration purposes to
underly the preferred stock and warrants that we issued in the September 30,
2005 financing transaction, then 37,106,885 shares of common stock will be
issued and outstanding on a fully diluted basis.

The fewer shares that are issuable upon exchange of the preferred stock and/or
exercise of the warrants, the less the dilution that will be experienced by our
stockholders prior to the September 30, 2005 financing transaction. It is
possible that we will issue fewer shares than the 10,937,500 shares we estimated
to be issuable for purposes of this registration statement. For instance, less
than 10,937,500 shares may be issuable if we do not pay dividends in the form of
common stock, if the amount of dividends that accrues is less than the $5.9
million we have assumed registration purposes (for example if preferred stock is
exchanged or redeemed prior to September 30, 2010, if our dividend payment
obligation is suspended due to our common stock's exceeding minimum trading
prices), if the average price per share of common stock used to issue dividends
is greater than the $2.00 figure we estimated (in which case fewer shares will
be issuable to satisfy our dividend obligations), or if there are no
antidilution adjustments to the exchange rate of the preferred stock and/or the
exercise price of the warrants. Conversely, it is possible that we will issue in
excess of the 10,937,500 shares we estimated for purposes of this registration
statement, for example, if dividends that actually accrue are in excess of $5.9
million (which may occur if preferred stock remains outstanding longer than five
years), if the average price per share of common stock used to pay dividends is
less than the $2.00 figure we estimated or if antidilution adjustments reduce
the exchange rate of the preferred stock and/or the exercise price of and number
of shares underlying the warrants.

table, we have disregarded the limitations on ownership applicable to the
Selling Stockholders under the terms of the preferred stock and warrants we
issued to them in the September 30, 2005 financing transaction (described under
"Liquidity and Capital Resources; Transactions in 2005 - Private Placement
Financing Completed September 30, 2005," above) and, as to two particular
Selling Stockholders, North Sound Legacy International Limited and North Sound
Legacy Institutional Fund LLC, for purposes of setting forth ownership in the
above table, we have also disregarded a written agreement with us whereby these
Selling Stockholders agreed not to exercise any voting rights with respect to
their preferred stock to the extent that doing so would exceed 4.99% of the
shares of common stock then outstanding. According to the foregoing, the Selling
Stockholders do not have "beneficial ownership" of all shares of common stock
underlying the preferred stock and warrants we issued to them in the September
30, 2005 financing transaction as calculated pursuant to Rule 13d-3 of the Rules
and Regulations under the Securities Exchange Act of 1934, as amended, however,
we are reporting their interest as ownership in the above table to disclose all
underlying shares that we are registering on behalf of the Selling Stockholders
by way of the registration statement of which this prospectus is a part.
Furthermore, certain of the Selling Stockholders are related entities (as
indicated in their respective names and addresses), and therefore although
presented individually in the table above, their shares should be considered
aggregated for purposes of determining the concentration of ownership by those
related entities. In addition, the number of shares owned before offering
indicated above for the four ProMed entities included in the above table does
not reflect 727,729 shares of common stock beneficially owned by Promed
Management, Inc. or 244,216 shares of common stock beneficially owned by ProMed
Asset Management, LLC, both of which we believe to be affiliates of the four
ProMed entities which are among the Selling Stockholders.

** Ownership of shares set forth in this table is different from beneficial
ownership of shares if ownership presented was "beneficial ownership" calculated
pursuant to Rule 13d-3 of the Rules and Regulations under the Securities
Exchange Act of 1934, as amended. Rather, percentage of ownership of shares set
forth in this table is based the number of shares owned by each Selling
Stockholder, as a percentage of 30,361,228 shares of common stock outstanding,
which includes 19,423,728 shares of common stock outstanding and available to
trade publicly on November 30, 2005, plus all 10,937,500 shares of common stock
that we are registering hereunder on behalf of the Selling Stockholders.

*** Includes those shares we are registering hereunder on behalf of each Selling
Stockholder, calculated to include a 25% allowance over the number of shares we
calculated for the securities we sold to the Selling Stockholders on September
30, 2005, as described under "Determination of Number of Shares to Be
Registered," above.

**** Assume that the Selling Stockholders do not acquire or dispose of any
shares of common stock and that the Selling Stockholders sell all shares of
common stock we are registering hereunder on their behalf.

***** Thomas McCauley is the ultimate managing member of North Sound Capital
LLC, which may be deemed the beneficial owner of the securities held in its
capacity as the managing member of North Sound Legacy Institutional Fund LLC and

who are the holders of record of such securities. As the managing member or

                              PLAN OF DISTRIBUTION


Each Selling Stockholder of our common stock and any of their pledgees,
transferees, donees, assignees and successors-in-interest may, from time to
time, sell any or all of their shares of common stock on the market or exchange
on which the common stock is listed or quoted for trading (currently the
American Stock Exchange, or, AMEX) or any other stock exchange, market or
trading facility on which the shares are traded or in private transactions.
These sales may be at fixed or negotiated prices. A Selling Stockholder may use
any one or more of the following methods when selling shares:

      o     ordinary brokerage transactions and transactions in which the
            broker-dealer solicits purchasers;

      o     block trades in which the broker-dealer will attempt to sell the
            shares as agent but may position and resell a portion of the block
            as principal to facilitate the transaction; "at the market" to or
            through market makers into an existing market for the shares;

      o     "at the market" to or through market makers into an existing market
            for the shares;

      o     purchases by a broker-dealer as principal and resale by the
            broker-dealer for its account;

      o     an exchange distribution in accordance with the rules of the
            applicable exchange;

      o     privately negotiated transactions;

      o     settlement of short sales entered into after the date of this
            prospectus;

      o     broker-dealers may agree with the Selling Stockholders to sell a
            specified number of such shares at a stipulated price per share;

      o     a combination of any such methods of sale;

      o     through transactions in options, swaps or other derivative
            securities, whether exchange-listed or otherwise; or

      o     any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act of 1933, as amended, if available, rather than under this
prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other
broker-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. Each Selling Stockholder does not expect these commissions and
discounts relating to its sales of shares to exceed what is customary in the
types of transactions involved.

In connection with the sale of common stock or interests therein, the Selling
Stockholders may enter into hedging transactions with broker-dealers or other
financial institutions, which may in turn engage in short sales of the common
stock in the course of hedging the positions they assume. To the extent
permitted by the applicable rules of the American Stock Exchange, the Selling
Stockholders may also sell shares of common stock short and deliver these
securities to close out their short positions, or loan or pledge the common
stock to broker-dealers that in turn may sell these securities. The Selling
Stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more
derivative securities which require the delivery to such broker-dealer or other
financial institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this
prospectus (as supplemented or amended to reflect such transaction).

We are required to pay certain fees and expenses incurred by us incident to the
registration of the shares. We have agreed to indemnify the Selling Stockholders
against certain losses, claims, damages and liabilities, including liabilities
under the Securities Act.

Each Selling Stockholder has advised us that it has not entered into any
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the resale shares. There is no underwriter or coordinating
broker acting in connection with the proposed sale of the resale shares by the
Selling Stockholders.

We agreed to keep this prospectus effective until the earlier of the date on
which (i) the shares may be resold by the Selling Stockholders without
registration and without regard to any volume limitations by reason of Rule
144(e) under the Securities Act or any other rule of similar effect and (ii) all
of the shares have been sold pursuant to the prospectus or Rule 144 under the
Securities Act or any other rule of similar effect. The resale shares will be
sold only through registered or licensed brokers or dealers if required under
applicable state securities laws. In addition, in certain states, the resale
shares may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.


                                       85


Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the resale shares may not simultaneously engage
in market making activities with respect to our common stock for a period of two
business days prior to the commencement of the distribution. In addition, the
Selling Stockholders will be subject to applicable provisions of the Exchange
Act and the rules and regulations thereunder, including Regulation M, which may
limit the timing of purchases and sales of shares of our common stock by the
Selling Stockholders or any other person. We will make copies of this prospectus
available to the Selling Stockholders, and have informed them of the need to
deliver a copy of this prospectus to each purchaser at or prior to the time of
the sale.


                                 TRANSFER AGENT


The transfer agent and registrar for our common stock is Continental Stock
Transfer & Trust Company, 17 Battery Place, New York, NY 10004. We act as our
own transfer agent for our preferred stock, warrants and stock options.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Diomed Holdings, Inc.

We have audited the accompanying consolidated balance sheets of Diomed Holdings,
Inc. as of December 31, 2004 and 2003, and the related  consolidated  statements
of operations,  stockholders'  equity and comprehensive  income (loss), and cash
flows for each of the two years in the period ended  December  31,  2004.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. The Company is not required to
have, nor were we engaged to perform, an audit of its internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designating audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Company's internal control over financial
reporting. Accordingly, we express no such opinion. Our audits also included
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Diomed Holdings,
Inc. and subsidiaries at December 31, 2004 and 2003, and the results of their
operations and their cash flows for each of the two years in the period ended
December 31, 2004, in conformity with accounting principles generally accepted
in the United States of America.

statements.

                              DIOMED HOLDINGS, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31, 2004

(1) OPERATIONS

The Company develops and  commercializes  minimally  invasive medical procedures
that employ its laser technologies and associated disposable products. Using its
proprietary  technology,  including  its  exclusive  rights to U.S.  Patent  No.
6,398,777, the Company currently focuses on endovenous laser treatment (EVLT(R))
of varicose  veins.  The Company also develops and markets lasers and disposable
products for photodynamic therapy (PDT) cancer procedures and products for other
clinical applications, including dental and general surgical procedures.

In developing and marketing its clinical solutions, the Company uses proprietary
technology and aims to secure strong  commercial  advantages over competitors by
obtaining exclusive commercial  arrangements,  gaining governmental approvals in
advance of others,  developing  and  offering  innovative  practice  enhancement
programs  including  physician training and promotional  materials.  To optimize
revenues, the Company focuses on clinical procedures that generate revenues from
both capital  equipment  and  disposable  products,  such as procedure  kits and
optical fibers.

The Company's high power  semiconductor  diode lasers combine clinical efficacy,
operational   efficiency  and  cost  effectiveness  in  a  versatile,   compact,
lightweight,  easy-to-use  and  easy-to-maintain  system.  Along with lasers and
single-use  procedure kits for EVLT(R),  the Company provides its customers with
state of the art physician training and practice development support.

In 2001,  the  Company  pioneered  the  commercialization  of  endovenous  laser
treatment  (EVLT(R)),  an innovative  minimally invasive laser procedure for the
treatment  of  varicose  veins  caused by  greater  saphenous  vein  reflux.  In
September  2001, the Company was the first company to receive the CE mark of the
European Economic Union for approval for endovenous laser treatment with respect
to  marketing  EVLT(R) in Europe.  In January  2002,  the  Company was the first
company to receive Food and Drug Administration ("FDA") clearance for endovenous
laser  treatment of the greater  saphenous  vein. In December  2004, the Company
received FDA clearance to expand the application of EVLT(R) to other superficial
veins in the lower extremities.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying  consolidated  financial  statements reflect the application of
certain  accounting  policies as described below and elsewhere in these notes to
consolidated financial statements.

(a) Principles of Consolidation

These  financial  statements  include the accounts of the Company and its wholly
owned  subsidiaries.   All  significant  intercompany   transactions  have  been
eliminated.

(b) Basis of Presentation

All share and per  share  information  included  in the  accompanying  financial
statements for all periods presented have been restated to retroactively reflect
the  effect  of the 1:25  reverse  stock  split  that the  Company  implemented,
effective June 17, 2004.

(c) Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States  requires  management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying  notes.  Estimates and assumptions  principally relate to reserves,
including inventory,  doubtful accounts receivable, and product warranty. Actual
results could differ from those estimates.

(d) Cash and Cash Equivalents

Cash and cash equivalents consists of short-term, highly liquid investments with
original maturity dates of 90 days or less.


                                      F-9


                              DIOMED HOLDINGS, INC.
              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                DECEMBER 31, 2004

(e) Foreign Currency Translation

Assets and  liabilities of the foreign  subsidiary are translated at the rate of
exchange in effect at year-end.  Results of operations are translated  using the
weighted  average   exchange  rate  in  effect  during  the  year.   Translation
adjustments,  resulting  from  changes  in the  rate  of  exchange  between  the
subsidiary's  functional  currency  and the U.S.  dollar,  are included in other
comprehensive  income (loss) with the cumulative  effect  included as a separate
component  of  stockholders'  equity in the  accompanying  consolidated  balance
sheets.  Transaction gains and losses, resulting from the revaluations of assets
and liabilities denominated in other than the functional currency of the Company
or its  subsidiaries,  are  included  in  operating  expenses  for  all  periods
presented.

(f) Revenue Recognition

Revenue from product sales is recognized  when title passes to the customer,  as
long as there is persuasive evidence of an arrangement, the sales price is fixed
and determinable and collection of the related receivable is reasonably assured.
The Company  provides for estimated  product  returns and warranty  costs at the
time of  product  shipment.  In  December  1999,  the  Securities  and  Exchange
Commission  (SEC)  issued  Staff  Accounting  Bulletin  (SAB) No.  101,  Revenue
Recognition  in Financial  Statements,  which  establishes  guidance in applying
generally  accepted  accounting  principles to revenue  recognition in financial
statements.   In  December  2003,  the  SEC  published  SAB  No.  104,   Revenue
Recognition,  which supersedes and rescinds the accounting guidance contained in
SAB No. 101 related to multiple-element revenue arrangements that was superseded
by EITF Issue No. 00-21 Revenue  Arrangements  with Multiple  Deliverables.  The
Company has determined that its existing  revenue  recognition  practices comply
with the requirements of SAB No. 104 for all periods presented.

(g) Inventories

Inventories  are valued at the lower of cost  (first-in,  first-out)  or market.
Work-in-progress   and  finished   goods   consist  of   materials,   labor  and
manufacturing overhead. Inventories consist of the following:


                                             December 31,
                                        2004             2003
                                     ----------       ----------
Raw materials                        $  838,390       $  856,886
Work-in-progress                        502,905          456,934
Finished goods                          863,090          578,421
                                     ----------       ----------
                                     $2,204,385       $1,892,241
                                     ==========       ==========

(h) Property and Equipment

The Company  records  property and equipment at cost.  The Company  provides for
depreciation  and  amortization  using the  straight-line  method by  charges to
operations in amounts that allocate the cost of the assets over their  estimated
useful lives as follows:

Description                                         Useful Life
- -----------                                         -----------
Office equipment and furniture and fixtures         2-5 years
Manufacturing equipment                             2-5 years
Leasehold improvements                              Lesser of estimated useful
                                                    life or life of lease


                                      F-10


                              DIOMED HOLDINGS, INC.
              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                DECEMBER 31, 2004

Depreciation expense for the years ended December 31, 2004 and 2003 was $482,739
and $380,357, respectively.

(i) Intangible Assets

Intangible  assets are  recorded  at cost and  consist of  manufacturing  rights
acquired in 2001 and the EVLT(R) patent rights  acquired in September 2003 (Note
15). The  manufacturing  rights are being  amortized over a five-year  estimated
useful life.  Amortization  expense  relating to these  manufacturing  rights of
approximately  $197,000 for each of the years ended  December 31, 2004 and 2003,
is included in general and administrative expense. The EVLT(R) patent rights are
being amortized over the remaining 16-year life of the patents, and amortization
expense  relating  to the  EVLT(R)  patent  rights of  $294,000  and  $98,000 is
included  in the cost of goods sold for the years  ended  December  31, 2004 and
2003, respectively.

(j) Long Lived Assets

The Company evaluates  long-lived assets,  such as intangible assets,  equipment
and leasehold  improvements,  for  impairment in  accordance  with  Statement of
Financial  Accounting Standards ("SFAS") No. 144, Accounting for the Impairment
or Disposal of  Long-Lived  Assets.  The Company  records an  impairment  charge
whenever events or changes in circumstances indicate that the carrying amount of
the assets may not be recoverable through the estimated undiscounted future cash
flows from the use of these assets. When any such impairment exists, the related
assets are written down to fair value. The Company did not incur any impairments
in the years ended December 31, 2004 and 2003.

(k) Fair Value of Financial Instruments

The  carrying  amounts  of  the  Company's  cash,  cash  equivalents,   accounts
receivable  and accounts  payable  approximate  fair value due to the short-term
nature of these  instruments.  The carrying  amounts of debt issued  pursuant to
agreements with banks' capital lease  obligations  and various debt  instruments
approximate fair value as the interest rates on these instruments fluctuate with
market interest rates.

(l) Concentration of Credit Risk and Significant Customers

Financial  instruments that subject the Company to credit risk primarily consist
of cash, cash equivalents and trade accounts receivable.  The Company places its
cash and cash equivalents in established financial institutions. The Company has
no significant  off-balance-sheet  concentration  of credit risk such as foreign
exchange contracts, options contracts or other foreign hedging arrangements. The
Company has not experienced any significant  losses related to receivables  from
any individual  customers or groups of customers in any specific  industry or by
geographic area.

Accounts  receivable are customer  obligations due under normal trade terms. The
Company sells its products to private  physicians,  hospitals,  health  clinics,
distributors  and OEM customers.  The Company  generally  requires  signed sales
agreements,  non-refundable  advance payments,  although collateral is generally
not required,  and purchase orders depending upon the type of customer.  Letters
of  credit  may be  required  in  certain  circumstances.  Some  customers  seek
equipment  financing from third party leasing  agents,  which the Company is not
party to and bears no credit risk.  Accounts  receivable is stated at the amount
billed to the customer less a valuation allowance for doubtful accounts.  Senior
management  reviews  accounts  receivable on a monthly basis to determine if any
receivables could  potentially be  uncollectible.  The Company includes specific
accounts  receivable  balances that are  determined to be  uncollectible  in its
overall  allowance  for  doubtful  accounts.  After all  attempts  to  collect a
receivable  have failed,  the  receivable is written off against the  allowance.
Based on available information,  the Company believes its allowance for doubtful
accounts as of  December  31,  2004 is  adequate.  The  allowance  for  doubtful
accounts  as  of  December  31,  2004  and  2003  was  $223,105,  and  $209,167,
respectively.

No  customers  accounted  for greater  than 10% of total  revenues in 2004.  One
customers  accounted  for greater than 10% of accounts  receivable  in 2004.  No
customers  accounted  for greater than 10% of total  revenues or gross  accounts
receivable in 2003.

                                DECEMBER 31, 2004

(m) Accounting for Stock-Based Compensation

The Company  accounts  for its  employee  stock-based  compensation  plans under
Accounting  Principles  Board  Opinion No. 25,  Accounting  for Stock  Issued to
Employees, utilizing the intrinsic value method. Accordingly,  compensation cost
for stock options issued to employees is measured as the excess,  if any, of the
fair market price of the Company's stock at the date of the fixed grant over the
amount an employee must pay to acquire the stock.  SFAS No. 123,  Accounting for
Stock-Based Compensation, as amended by SFAS No. 148, Accounting for Stock-Based
Compensation - Transition and Disclosure,  establishes a fair value based method
of accounting for stock-based  compensation  plans.  The Company has adopted the
disclosure  only  alternative  under SFAS No. 123,  with respect to its employee
stock compensation  plan, which requires  disclosure of the pro forma effects on
net  loss and loss per  share  as if SFAS No.  123 had been  adopted  as well as
certain other information. (See Note 8d)

The pro forma effect of applying SFAS No. 123 in 2004 and 2003 is as follows:



                                                                       December 31,
                                                                  2004               2003

(n) Research and Development Expenses

The Company charges research and development expenses to operations as incurred.

(o) Comprehensive Income (Loss)

SFAS  No.  130,  Reporting  Comprehensive  Income,  requires  disclosure  of all
components of comprehensive  income (loss).  Comprehensive  income is defined as
the change in stockholders' equity of a business enterprise during a period from
transactions and other events and circumstances  from nonowner sources.  For all
periods  presented,  comprehensive  loss  consists of the Company's net loss and
changes in cumulative  translation adjustment account. The Company has disclosed
comprehensive  income  (loss)  for all  periods  presented  in the  accompanying
consolidated statements of stockholders' equity and comprehensive income (loss).

(p) Income Taxes

The Company follows the provisions of SFAS No. 109, Accounting for Income Taxes.
Deferred  income taxes are provided on temporary  differences  that arise in the
recording of transactions for financial and tax reporting purposes and result in
deferred  tax  assets and  liabilities.  Deferred  tax assets are  reduced by an
appropriate valuation allowance if, in management's  judgment, it is more likely
than not that the  deferred  tax asset will not be  realized.  Tax  credits  are
accounted  for as  reductions  of the current  provision for income taxes in the
year in which the related expenditures are incurred.

(q) Other Recent Accounting Pronouncements

In December 2004,  the FASB revised SFAS No. 123,  Share Based Payment,  or SFAS
No. 123R.  SFAS No. 123R  supersedes  APB Opinion No. 25,  Accounting  for Stock
Issued to Employees, and amends Statement No. 95, Statement of Cash Flows. Under
SFAS No. 123R,  companies must calculate and record in the income  statement the
cost of equity  instruments,  such as stock  options,  awarded to employees  for
services received. The cost of the equity instruments is to be measured based on
the fair value of the  instruments  on the date they are granted and is required
to be  recognized  over the period  during which the  employees  are required to
provide  services  in  exchange  for the equity  instruments.  SFAS No.  123R is
effective for the Company in the first interim period  beginning  after December
15, 2005.


                                      F-12


                              DIOMED HOLDINGS, INC.
              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                DECEMBER 31, 2004

The  adoption of SFAS No. 123R is expected to have a  significant  impact on the
Company's financial  statements.  The impact of adopting SFAS No. 123R cannot be
accurately estimated at this time, as it will depend on the market value and the
amount of share-based awards granted in future periods.

(3) NET LOSS PER SHARE

Net loss per share is computed  based on the guidance of SFAS No. 128,  Earnings
per Share. SFAS No. 128 requires  companies to report both basic loss per share,
which is based on the weighted average number of common shares outstanding,  and
diluted loss per share,  which is based on the weighted average number of common
shares  outstanding and the weighted average number of dilutive potential common
shares  outstanding.  As a result of the losses  incurred by the Company for the
years  ended  December  31,  2004 and 2003,  all  potential  common  shares were
antidilutive  and thus  were  excluded  from  the  diluted  net  loss per  share
calculations.

The following table summarizes securities outstanding, adjusted for the 1 for 25
reverse  split  effective  June 17,  2004,  as of each  year-end  which were not
included in the  calculation of diluted net loss per share since their inclusion
would be antidilutive.

(A) On October 25, 2004, in connection  with the 2004 private  placement  equity
and debt  financing  discussed  in Note 16, the  Company  issued  $7,000,000  in
convertible notes. These notes are convertible at a rate of $2.29 per share.

(B) On September 3, 2003, in connection with the equity  financing  discussed in
Note 14, the Company  issued  securities to pay the fees of the placement  agent
that it  engaged  in April  2003 to assist in  obtaining  financing.  In lieu of
paying this fee in cash, the Company  issued to the placement  agent $495,000 in
secured bridge notes plus warrants to purchase up to 1,635,163  shares of common
stock. Of these warrants,  701,663 warrants have an exercise price of $0.025 per
share,  247,500  warrants have an exercise  price of $2.00 per share and 686,000
warrants  have an  exercise  price  of  $2.50  per  share.  These  warrants  are
exercisable for five years.  Additionally,  the warrants issued to the placement
agent were subject to an anti-dilution adjustment for future equity investments.
This adjustment was triggered on October 25, 2004, and as such the warrants with
exercise  prices of $2.00 were adjusted to $1.93 and 7,588  additional  warrants
were issued,  and the warrants  with  exercise  prices of $2.50 were adjusted to
$2.32 and 48,145 additional warrants were issued. Pursuant to its agreement with
Sunrise,  on October 25, 2004 the  Company  also issued  warrants to purchase an
additional  73,539  shares of common  stock,  at an exercise  price of $2.01 per
share because,  under the April 2003 agreement with Sunrise,  the Company agreed
to  pay  Sunrise   commissions  for  subsequent  sales  of  securities  made  to
participants  in the 2003 financing  within one year of the  termination of that
agreement.  As of December 31, 2004, a total of 1,625,120 of the warrants issued
to Sunrise, as adjusted for anti-dilution and commission, had been exercised and
139,315 warrants were unexercised and remained outstanding.

Warrant  holders who  exercised  their  warrants to date have used the  cashless
exercise feature of these warrants.  As a result of the cashless  exercise,  the
warrant holders did not pay cash for the exercise price of the warrants,  and as
a result,  the  Company  was not  required  to issue  the full  amount of shares
underlying  the warrants  exercised.  For example,  as of December 31, 2004, the
Company issued a total of 1,377,231  shares of common stock upon exercise of the
1,625,120 warrants.

which the Company issued a total of 163,399 shares of common stock.

a) Promissory Note Issued to Customer

In October 2000, a customer,  Axcan Pharma,  Inc., advanced the Company $936,000
to secure  certain key  materials.  In  September  2001,  the  Company  issued a
Promissory  Note to this customer in the amount of the advance.  The  Promissory
Note bore  interest,  at an annual rate of 8.5%,  which is payable  quarterly in
arrears.  The Promissory Note had a maturity date of January 1, 2004 and did not
provide  for  conversion  rights  into  equity.  As of December  31,  2003,  the
principal  amount and accrued  interest under this  Promissory Note was $936,000
and  $20,053,  respectively.  On January 2, 2004,  the Company  fully repaid the
Promissory Note and accrued interest in accordance with its terms.

b) Secured Bridge Notes - September 3, 2003

On September 2, 2003, the Company  entered into  agreements  that provide Equity
Financing with 119 Investors who agreed to purchase  10,177,500 shares of Common
Stock for an aggregate purchase price of $23,200,000. Twenty-two million dollars
of the aggregate  purchase price was payable in cash, and $1,200,000 was paid by
conversion of the Company's Class D notes at the second closing. (See Note 14)

At the first closing of the Equity  Financing,  the Company issued $6,995,000 in
principal  amount of Secured Bridge Notes (the "Secured  Bridge  Notes"),  which
accrued  interest at an annual rate of 8% and were  convertible  into  3,497,500
shares of  common  stock at $2.00 per  share.  The  Secured  Bridge  Notes  were
convertible upon favorable  stockholder  approval of the Equity Financing at the
annual  meeting held on November 25, 2003. The Secured Bridge Notes were secured
by a security  interest in collateral that included the Company's rights to U.S.
Patent No.  6,398,777 and related foreign patents for endovenous laser treatment
of varicose  veins (the "EVLT  Patent").  These patents relate to the technology
that the Company acquired on September 3, 2003 underlying the Company's  EVLT(R)
product  line (See Note 15) and the  security  interest  previously  granted  to
secure the Class E Notes due  January 1, 2006 that the  Company  had  previously
issued  (See Note 8). The Class E Notes were fully paid at the first  closing of
the Equity Financing in advance of the January 1, 2006 maturity date to increase
the collateral available for the Secured Bridge Notes.

                                DECEMBER 31, 2004

Under the terms of the Equity  Financing,  at the second closing on November 25,
2003, the aggregate  principal amount of the Secured Bridge Notes converted into
3,497,500  shares of Common Stock at a purchase price of $2.00 per share.  Also,
on November 25, 2003, the Company  issued an additional  65,287 shares of Common
Stock to pay accrued  interest  in the amount of $130,573 on the Secured  Bridge
Notes. Of the Secured Bridge Notes, $6,500,000 in aggregate principal amount was
issued at the first closing in exchange for a purchase price equal to $6,500,000
paid in cash.  Gibralt U.S. and the other three holders of the Company's Class E
notes purchased  $2,000,000 of Secured Bridge Notes at $2.00 per share, the same
price as paid by the other Investors who purchased Secured Bridge Notes. Each of
the  other  Investors  who  subscribed  to  purchase  securities  in the  Equity
Financing purchased on a pro rata basis $4,500,000 in aggregate principal amount
of the Secured  Bridge  Notes.  The Company  also issued  $495,000 in  principal
amount of the Secured Bridge Notes to the placement  agent in partial payment of
its fee.

The  Company  recognized  a  beneficial  conversion  feature  in the  amount  of
$6,995,000,  upon favorable  stockholder approval of the Equity Financing at the
annual  meeting  held on November  25, 2003,  with a  corresponding  increase in
additional  paid-in  capital.  This  discount  was fully  amortized  to non-cash
interest  expense  when the Secured  Bridge Notes  converted to equity.  The net
impact  on  stockholders'  equity  was zero  when the net  loss,  including  the
amortization of the discount, was fully reflected in the accumulated deficit.

In connection with the first closing, the Company incurred $651,923 in placement
agent and legal fees,  including a $495,000  fee due to be paid in cash that the
placement  agent  invested  in  the  Secured  Bridge  Notes.  These  costs  were
capitalized  as deferred  financing  costs and were being  amortized to interest
expense  over the life of the  notes,  such  that the full  amount  of costs was
amortized by the earlier of the  maturity  date of the notes or by the month the
notes were  converted  into equity.  For the year ended  December 31, 2003,  the
Company  recognized  $651,923 in interest expense pertaining to the amortization
of the deferred  financing costs,  and accordingly,  the balance of the deferred
financing costs was zero as of December 31, 2003.

In  connection  with the first  closing,  the Company  recognized  an additional
placement agent fee, in the amount of $1,798,579, for 247,500 warrants issued to
a  placement  agent.  The fee was  recorded  as a deferred  financing  cost upon
stockholder  approval of the Equity  Financing  on  November  25,  2003,  with a
corresponding  increase in additional  paid-in capital.  The deferred  financing
cost was fully amortized to interest  expense in the period in which the Secured
Bridge Notes  converted to equity.  The net impact on  stockholders'  equity was
zero  when the net  loss,  including  the  deferred  financing  cost,  was fully
reflected in the accumulated deficit.

c) EVLT(R) Technology Acquisition - September 3, 2003

On  September 3, 2003,  the Company  acquired  rights to the EVLT Patent,  which
relates to the  technology  underlying  the Company's  EVLT(R)  product line. On
September 3, 2003, the Company paid Endolaser  Associates  $1,500,000 in cash in
exchange  for the  exclusive  license  and  agreed to make  additional  payments
totaling $2,500,000 in 10 quarterly installments of $250,000 each, commencing in
the fourth  quarter of 2003.  The Company  recorded a liability in the amount of
$2,500,000,  net of a $254,000  discount based on an annual interest rate of 8%,
to  reflect  the  imputed  interest  on the  liability.  The  discount  is being
amortized  to interest  expense  over the period of the  additional  installment
payments.  The Company has made five quarterly  installments totaling $1,250,000
since  acquiring the rights.  Accordingly,  at December 31, 2004,  the remaining
liability was $1,250,000 net of debt discount of $72,000. (See Note 15)

d) Private  Placement  Equity and Debt  Financing  Entered into on September 28,
2004

On October 25, 2004, the Company completed the Private Placement Equity and Debt
Financing  entered  into on  September  28,  2004 and  discussed  in Note 17. In
connection  with the financing,  the Company issued  $7,000,000 in debt which is
convertible  into  common  shares at $2.29 per share.  The  Company  also issued
warrants to purchase 1,832,461 shares of common stock to investors who purchased
the  convertible  debt.  Accordingly,  the Company  recorded a debt  discount of
$2,261,000  in relation to the  convertibility  feature of the debt and the fair
value of the warrants using the Black Scholes option pricing model. The discount
is being amortized to non-cash interest expense over the term of the notes, such
that the full amount of the  discount  will be  amortized  by the earlier of the
maturity  date of the notes or the  conversion  of the notes to equity.  The net
impact on  stockholders'  equity will be zero when the net loss,  including  the
amortization of the discount,  is fully  reflected in the  accumulated  deficit.
Accordingly,  the notes  were  originally  recorded  at net value of  $4,738,601
(after the $2,261,399  discount).  In the year ended December 31, 2004,  $78,248
was recognized in non-cash  interest expense  pertaining to this amortization of
the discount. The balance of the notes at December 31, 2004 was $4,816,849,  net
of unamortized debt discount of $2,183,151.

e) Capital Equipment Leases

Leased assets included in property and equipment primarily include manufacturing
equipment.  Depreciation  expense  for leased  equipment  during the years ended
December 31, 2004 and 2003 was $12,238 and $36,823, respectively.

Future minimum debt payments required under these  arrangements at December 31,
2004 are as follows:

(7) INCOME TAXES

No provision for foreign,  federal or state income taxes has been  recorded,  as
the Company  incurred net  operating  losses for all periods  presented  for all
jurisdictions  in which it operates.  The Company has U.S. federal and state net
operating loss  carryforwards of approximately  $27,000,000 at December 31, 2004
to reduce  future  federal  income taxes,  if any.  These  carryforwards  expire
through 2024 and are subject to review and possible  adjustment  by the Internal
Revenue Service (IRS). The Company also has approximately $23,000,000 of foreign
net operating loss  carryforwards  at December 31, 2004 to reduce future foreign
income taxes, if any. These carryforwards do not have an expiration date.

                                DECEMBER 31, 2004

The Tax Reform Act of 1986 contains provisions that may limit the amount of U.S.
federal and state net operating loss and credit  carryforwards  that the Company
may  utilize  in any one year in the  event of  certain  cumulative  changes  in
ownership  over a  three-year  period in excess of 50%, as defined.  The Company
believes that its equity financing completed on November 25, 2003 and its equity
and debt financing  completed on October 25, 2004 may have triggered a change in
ownership  which,  in turn,  may limit the  utilization  of net  operating  loss
carryforwards in future years.

The  approximate  tax  effects  of  temporary  differences  that  give  rise  to
significant  portions of the Company's  deferred tax assets  primarily relate to
net operating loss  carryforwards  and amount to  approximately  $18,269,000 and
$12,740,000 as of December 31, 2004 and 2003, respectively.  It is the Company's
objective to become a profitable  enterprise  and to realize the benefits of its
deferred tax assets.  However, in evaluating the realizability of these deferred
tax assets, management has considered the Company's short operating history, the
volatility of the market in which it competes and the operating  losses incurred
to date,  and believes that,  given the  significance  of this evidence,  a full
valuation reserve against its deferred tax assets is required as of December 31,
2004  and  2003.  The  components  of the  Company's  deferred  tax  assets  are
approximately as follows:

                                             December 31,

(8) STOCKHOLDERS' EQUITY

(a) Issuance of Diomed Holdings,  Inc. Class A Convertible Preferred Stock ("Old
Class A Stock") in Diomed Merger

On February 14,  2002,  Diomed  Acquisition  Corp.  ("Acquisition"),  a Delaware
corporation  and a wholly-owned  subsidiary of Diomed  Holdings,  Inc., a Nevada
corporation formerly known as Natexco Corporation,  merged with and into Diomed,
Inc. (the  "Merger")  pursuant to an Agreement  and Plan of Merger,  dated as of
January 29, 2002.

Pursuant to the Merger agreement,  Diomed Holdings issued  (references to common
stock are without  adjustment  for the 1:25  reverse  split  effective  June 17,
2004):

- - 2,328,922.50  shares of its Old Class A Stock to the former holders of Diomed,
Inc.  common stock in exchange for  9,315,690  shares of common stock of Diomed,
Inc. issued and outstanding as of the effective time of the Diomed Merger, which
2,328,922.50  shares were  convertible  into 9,315,690 shares of Diomed Holdings
common stock; and

- - 1,362,500 of its Old Class A Stock to the former  holders of 2,725,000  shares
of Diomed,  Inc.  Series A  Preferred  Stock  issued and  outstanding  as of the
effective  time of the Merger.  These  shares were  convertible  into  5,450,000
shares of Diomed Holdings common stock.

On October 24, 2002, the Company's registration statement was declared effective
by the Securities and Exchange Commission.

On December  31,  2002,  according to the Class A  Convertible  Preferred  Stock
Certificate  of  Designation,  monthly  conversions  of the  Company's  Class  A
Convertible Preferred Stock ("Class A Stock") began converting into Common Stock
at the rate of 5% of the initial shares of the Class A Stock or 773,087  shares,
and were to  continue  to occur on the last day of each month  during the period
from January 2003 through January 2004. The remaining  4,638,531 shares of Class
A Stock were to convert in February 2004.

                                DECEMBER 31, 2004

Because the board of  directors  determined  that the effect of the  incremental
conversion of Class A Stock into common stock would impair the Company's ability
to procure additional equity  investments,  pursuant to its discretion under the
terms of the Class A Stock, the board voted to convert the remaining outstanding
shares of Class A Stock into common  stock on March 31, 2003,  and  accordingly,
zero shares of Class A Stock are outstanding at December 31, 2004 and 2003.

(b) Bridge Financings with Related Parties

(i) On December  27,  2002,  the  Company  completed  a  $2,000,000  bridge note
financing  with Gibralt  U.S.,  Inc. an affiliate of Samuel  Belzberg,  a former
director of the Company (the "December 2002 noteholder"  and,  together with the
three  persons to whom Gibralt  U.S.  subsequently  transferred  $500,000 of the
notes, the "December 2002  noteholders").  The financing included  $1,000,000 in
Class A secured notes and  $1,000,000 in Class B unsecured  notes due January 1,
2004. The notes accrued interest at an annual rate of 8%, payable upon maturity.

The notes were  convertible  into common  stock at the  election of the December
2002  noteholders  upon the occurrence of: (i) a financing  transaction,  (ii) a
liquidity event,  (iii) a merger or  reorganization,  or (iv) at any time during
the life of the notes, at the election of the holders of at least 66 2/3% of the
outstanding  principal amount of the notes. The notes,  including  principal and
accrued interest,  were convertible into common stock at 80% of the common stock
price at the time of conversion.

As  additional  consideration  for the  financing,  the  Company  issued  to the
December 2002  noteholders  warrants to purchase 333,334 shares of common stock.
The warrants were exercisable for a period of five years beginning June 27, 2003
at an exercise price of $6.50, which represented 110% of the market price of the
stock on December 26,  2002.  If,  prior to the  exercise of the  warrants,  the
Company  issued  common stock or common stock  equivalents  at a price per share
less than the  exercise  price of the  warrants,  the number of warrants and the
exercise price of the warrants were to be adjusted to the lower price per share.
In the event of a merger or  reorganization,  the warrants were convertible into
the kind and number of shares of common stock, other securities or property into
which the warrants  would have been converted if the warrants had been converted
into common stock based on the provisions of the merger or reorganization.

The  December  2002  noteholders  had the  right to  designate  a member  to the
Company's Board of Directors while the notes were  outstanding.  The Company was
required to obtain the advance  approval by the December  2002  noteholders  for
future financing transactions during the life of the notes.

On March 18, 2003, the initial  December 2002 noteholder sold and transferred to
three investors in a private transaction (i) $500,000 aggregate principal amount
of notes  ($250,000 of which were Class A notes and $250,000 of which were Class
B  notes)  and  (ii)  warrants  to  purchase  83,334  shares  of  common  stock.
Accordingly,  after taking this transfer into account, the initial December 2002
noteholder  owned  $1,500,000  aggregate  principal amount of notes ($750,000 of
which were Class A notes and  $750,000 of which were Class B notes) and warrants
to purchase 250,000 shares of common stock.

The  Company  recognized  the  $2,000,000  fair  value of the  warrants  and the
beneficial  conversion  feature related to the immediate  convertibility  of the
notes as a discount to the notes,  with a  corresponding  increase in additional
paid  in  capital.   The  value  ascribed  to  the  warrants  was  approximately
$1,200,000,  as calculated using the Black-Scholes option pricing model, and the
value ascribed to the beneficial  conversion  feature of the notes was $800,000.
The discount was to be amortized over the term of the notes to non-cash interest
expense,  such that the full amount of the  discount  would be  amortized by the
earlier of the maturity  date of the notes or conversion of the notes to equity.
The net  impact  on  stockholders'  equity  was to be zero  when  the net  loss,
including  the  amortization  of  the  discount,  was  fully  reflected  in  the
accumulated  deficit.  Accordingly,  the notes were  originally  recorded at net
value of zero (after the $2,000,000  discount).  For the year ended December 31,
2003,  $721,000 was recognized in non-cash  interest expense  pertaining to this
amortization  of  the  discount  prior  to the  May  2003  exchange  transaction
discussed below.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                DECEMBER 31, 2004

In connection with the bridge financing, the Company incurred $80,000 in related
legal fees. As of December 31, 2002,  these costs were  capitalized  as deferred
financing  costs and were to be amortized  to interest  expense over the life of
the notes,  such that the full amount of costs were  amortized by the earlier of
the  maturity  date of the notes or by the month the notes were  converted  into
equity.  The Company  expensed the balance of the deferred  financing costs upon
completion of the May 2003 exchange transaction. For the year ended December 31,
2003,  the  Company   recognized  $80,000  in  interest  expense  pertaining  to
amortization of the deferred financing costs, and,  accordingly,  the balance of
the deferred financing costs was zero as of December 31, 2003.

(ii) During the first  quarter of 2003,  it became clear that the Company  would
require additional working capital. In April 2003, the Company began discussions
with Gibralt U.S. with a view to its providing  interim financing in addition to
the interim  financing  that it had provided in December  2002. The Company also
began to consider a subsequent  financing expected to begin later in the quarter
to address its longer term capital needs. In late April,  the Company elected to
obtain up to  $1,200,000 of interim  financing  from Gibralt U.S. and two of its
directors.  At the same  time,  the  Company  proposed  a  restructuring  of the
securities  issued in December  2002 to improve its access to financial  markets
and enhance the  likelihood of a subsequent  financing.  Therefore,  the Company
offered to repurchase certain rights from the December 2002 noteholders that, in
light of then-current  market  conditions,  might have made it more difficult to
successfully complete a subsequent financing.

Using the Black  Scholes  valuation  methodology,  the  Company  calculated  the
monetary  value of the rights of the December 2002  noteholders to convert their
notes into shares of common  stock and the  monetary  value of the common  stock
purchase warrants. The Company further engaged Marshall & Stevens, Incorporated,
a professional  valuation  firm, to provide an opinion as to the valuations that
it had  calculated.  The price per share that the Company  employed to calculate
the number of shares equal to the monetary value of the rights that the December
2002  noteholders  would be surrendering was the presumed price per share of its
common stock after giving effect to the issuance of those shares.

At the time the Class A secured  notes and Class B unsecured  notes were issued,
the  Company  could not issue  more than  $1,000,000  in  secured  debt  without
obtaining  prior approval by its preferred  stockholders  under the terms of its
Class A Stock. On March 31, 2003, the Company converted all of its Class A Stock
into common  stock to  eliminate  its  convertibility  feature and its  apparent
negative impact on the Company's ability to obtain additional financing.  On May
7, 2003, the December 2002  noteholders  exchanged  their  $1,000,000  principal
amount of secured  Class A notes and  $1,000,000  principal  amount of unsecured
Class B notes  for  $2,000,000  principal  amount of  secured  Class C notes due
January 1,  2004.  On May 7,  2003,  the  Company  issued to the  December  2002
noteholders 20 shares of its Class C Preferred Stock, which was convertible into
1,084,690 shares of common stock, in exchange for eliminating the convertibility
feature of the $2,000,000 principal amount of notes and the warrants to purchase
333,334  shares of common stock,  as well as certain  other rights.  The Class C
Preferred  Stock was exchanged  for Class E Preferred  Stock on August 22, 2003.
(See Note 13)

(iii) On May 7, 2003, Gibralt U.S. and two of the Company's directors,  James A.
Wylie, Jr. and Peter Norris (the "May 2003  noteholders"),  committed to provide
financing of up to  $1,200,000  in the form of Class D secured  notes due May 6,
2004. The Company  issued the May 2003  noteholders an aggregate of 24 shares of
Class D Preferred  Stock,  which was  convertible  into 120,863 shares of common
stock.  The Class D Preferred Stock was exchanged for Class F Preferred Stock on
August 22, 2003.  (See Note 13) The Class D notes accrued  interest at an annual
rate of 8%, payable upon maturity.  As of July 7, 2003, the entire $1,200,000 in
interim  financing  had  been  funded.  The May  2003  noteholders  had the same
security  interest  and  registration   rights  granted  to  the  December  2002
noteholders.

The May 2003 noteholders had the right to participate in the Company's financing
contemplated for the second half of 2003 on the same terms and conditions as the
new investors by redeeming  their notes.  In determining  the price at which the
Company  sold its notes,  an  independent  committee  of the board of  directors
considered  the added risk that the May 2003  noteholders  would be accepting in
light of the uncertainty of the completion of the  contemplated  financing.  The
December 2002 notes provided that the corresponding noteholders had the right to
participate  in the next financing of the Company at a 20% discount to the price
to be paid by investors. Using this discount factor as a benchmark for assessing
the risk that the May 2003 noteholders  would be assuming,  among other factors,
the  independent   committee   authorized  the  issuance  of  preferred   shares
convertible  into 120,863  shares of common  stock,  allocated  according to the
noteholder's respective loan commitments.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                DECEMBER 31, 2004

(iv) On May 28, 2003,  the Company and the  December  2002  noteholders  amended
certain of the terms of the May 7, 2003 capital restructuring to: (i) extend the
due date of the Class C notes from January 1, 2004 until  January 1, 2006,  (ii)
increase  the rate of interest  payable on the Class C notes from 8.0% to 12.5%,
(iii)  provide for  mandatory  prepayments  of principal of the Class C notes in
amounts  up to 50% of  positive  quarterly  cash flow,  (iv) limit the  security
interest in inventory  that secures the Class C notes at  $3,271,000,  (v) waive
the  noteholders'  right of approval of future  financing  transactions and (vi)
extend  the  deadline  by  which  the  financing  was  to be  completed  without
triggering the noteholders' right of rescission,  from June 30, 2003 to July 31,
2003 (under the terms of the  restructuring if the  contemplated  financing were
not  completed by July 31, 2003 the December 2002  noteholders  had the right to
rescind the May 7, 2003 exchange transaction). On July 31, 2003, the deadline by
which the  financing was to be completed  without  triggering  the  noteholders'
right of rescission  was extended  until  November 15, 2003. On August 22, 2003,
the Class C notes were  exchanged for Class E notes  reflecting  these  modified
terms in principal  amounts equal to the principal  amounts of the Class C notes
exchanged.  The Class E notes were repaid in full with a portion of the proceeds
from the first closing of the equity financing.

The exchange of debt and  preferred  stock for the  elimination  of warrants and
modification  of  the  December  2002  notes  in  May  2003  was  treated  as an
extinguishment of the $2,000,000 debt. As a result, the fair market value of the
warrants and other consideration, which was limited to the remaining unamortized
discount on the December  2002 notes,  was recorded as a reduction in additional
paid in  capital  in the  amount of  $1,167,000  and the  remaining  unamortized
discount was reduced to zero.

The Company  recognized the $2,000,000  fair value of the preferred stock issued
with the Class E notes,  which was recorded as a discount to the notes, with the
offset as an increase in preferred  stock. The discount was to be amortized over
the term of the notes to non-cash interest expense, such that the full amount of
the discount  was to be  amortized  by the earlier of the  maturity  date of the
notes or early retirement of the notes.  The net impact on stockholders'  equity
was to be zero when the net loss,  including the  amortization  of the discount,
was fully  reflected in the  accumulated  deficit.  Accordingly,  the notes were
originally  recorded at net value of zero (after the  $2,000,000  discount).  On
September  3, 2003 the notes were fully  retired in advance of their  January 1,
2006 maturity date in order to expand the collateral available to the holders of
the  September  Secured  Bridge  Notes  while the Company  obtained  stockholder
approval to  complete  the Equity  Financing.  (See Notes 6b and 14) In the year
ended December 31, 2003,  $2,000,000 was recognized in non-cash interest expense
pertaining to this amortization of the discount.

(v) On May 28, 2003, the Company and the May 2003 noteholders amended certain of
the terms of the May 7, 2003 interim  financing to: (i) add a  requirement  that
100% of the Class D notes be  redeemed  into  common  stock in the  contemplated
financing at the same price per share and on the same terms as the new investors
if the Company  raises  $6,000,000 or more in gross proceeds and (ii) extend the
deadline for completion of the  contemplated  financing  without  triggering the
right of the May 2003  noteholders  to declare the Class D notes due and payable
to July 31, 2003. On July 31, 2003,  this date was further  extended to November
15,  2003.  On August 21, 2003,  this  deadline was extended to the business day
following any date after November 15, 2003,  which the Company and the Investors
in the Equity  Financing  agree to as the  second  closing  date.  At the second
closing of the Equity  Financing on November 25, 2003, the $1,200,000 in Class D
notes and accrued  interest in the amount of $48,233 were converted into 499,294
shares of common stock at $2.50 per share. (See Note 14)

The  Company  recognized  a $240,000  discount to the Class D Notes for the fair
value of the  preferred  stock,  which was  recorded as a discount to the notes,
with a  corresponding  increase  in  preferred  stock.  The  discount  was to be
amortized over the term of the notes to non-cash interest expense, such that the
full amount of the discount was amortized by the earlier of the maturity date of
the Class D notes or by the month the Class D notes were  converted into equity.
The net  impact on  stockholders'  equity/(deficit)  was zero when the net loss,
including  amortization  of the  discount,  was fully  reflected in  accumulated
deficit. In the year ended December 31, 2003, the Company recognized $240,000 in
non-cash interest expense pertaining to amortization of the discount.


                                      F-20


The  Company  recognized  a  beneficial  conversion  feature  in the  amount  of
$960,000,  which  was  recorded  as a  discount  to the  notes,  upon  favorable
stockholder  approval  of the equity  financing  at the annual  meeting  held on
November 25, 2003, with a corresponding  increase in additional paid in capital.
This discount was fully amortized to non-cash  interest expense in the period in
which the Class D notes  converted  to equity.  The net impact on  stockholders'
equity was zero when the net loss,  including the  amortization of the discount,
was fully reflected in the accumulated deficit.

In  connection  with the  interim  financing,  the Company  incurred  $51,000 in
related legal fees. These costs were capitalized as deferred financing costs and
were amortized to interest expense over the life of the Class D notes, such that
the full amount of costs were  amortized by the earlier of the maturity  date of
the Class D notes or by the period the Class D notes were converted into equity.
In the year ended December 31, 2003, the Company  recognized $51,000 in interest
expense  pertaining to this  amortization of the deferred  financing costs, and,
accordingly,  the  balance  of the  deferred  financing  costs  were  zero as of
December 31, 2003.

(c) Common Stock

The  figures  below  are  adjusted  to give  effect  to the 1:25  reverse  split
effective  June 17,  2004 for the  number of shares of common  stock,  price per
share, options and warrants.

In February 2002, the Company issued 200,000 shares of its Common Stock,  $0.001
par  value per  share,  at a price of  $50.00  per share in a private  placement
financing in  connection  with the Diomed  Merger,  resulting in proceeds net of
offering costs of $7,900,000.

After the Migratory  Merger on May 13, 2002 in which the Company  reincorporated
from Nevada to Delaware  (See Note 12),  the Company had  authorized  80,000,000
shares  of  Common  Stock,  $0.001  par  value,  of  which  568,000  shares  are
outstanding (excluding securities which may be converted into or exercisable for
Common  Stock),  having been  automatically  issued to the holders of the Common
Stock issued by Diomed Holdings Nevada by virtue of the Migratory Merger.

Under the Merger agreement, the Company was obligated to use its best efforts to
file a  registration  statement  with  the  Securities  Exchange  Commission  to
register  for  resale  common  shares  that it issued in the  private  placement
offering and common shares that it issued to former  stockholders,  and to cause
the  registration  statement  to be  declared  effective.  In the event that the
Company  failed  to file or cause  the  registration  statement  to be  declared
effective within 240 days of completing the Merger or remain  effective  through
the  first  anniversary  of the  Merger,  the  Company  was  required  to  issue
additional  shares of its common stock, up to a maximum of 4% of the shares held
by each of the February 2002 private placement  investors.  On October 24, 2002,
the Company received  approval of its  registration  statement by the Securities
and  Exchange  Commission  and  accordingly  issued the  February  2002  private
placement investors an additional aggregate of 2,000 shares of Common Stock.

On December  31,  2002,  according to the Class A  Convertible  Preferred  Stock
Certificate of Designation,  monthly  conversions of the Company's Class A Stock
began  converting  into Common Stock at the rate of 5% of the initial  shares of
the Class A Stock or 773,087  shares,  and were to continue to occur on the last
day of each month during the period from January 2003 through  January 2004. The
remaining 4,638,531 shares of Class A Stock were to convert in February 2004.

As of December 31, 2002, the Company had authorized  80,000,000 shares of Common
Stock, $0.001 par value, of which 15,023,087 (600,923 after giving effect to the
1:25 reverse split implemented June 17, 2004) shares were outstanding.

Because the board of  directors  determined  that the effect of the  incremental
conversion of Class A Stock into common stock would impair the Company's ability
to procure additional equity  investments,  pursuant to its discretion under the
terms  of the  Class A Stock,  the  board  determined  to  cause  the  remaining
outstanding  shares of Class A Stock to convert  into common  stock on March 31,
2003.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                DECEMBER 31, 2004

As of March  31,  2003,  the  Company  had  1,188,470  shares  of  common  stock
outstanding and zero shares of Class A Stock outstanding.

On May 7, 2003, the Company issued Class C Preferred Stock to the holders of the
notes and  warrants  it had issued in  December  2002 in  exchange  for  certain
modifications  to those  notes and  warrants  including  the  redelivery  of the
warrants  to the  Company for  cancellation.  These  shares of Class C Preferred
Stock were convertible  into 1,084,690 shares of common stock upon  satisfaction
of certain conditions.  The modifications to the notes included  eliminating the
convertibility  feature of the notes and eliminating the  noteholders'  right to
approve a future financing transaction.

On May 7, 2003,  the Company also issued  $1,200,000 in Class D notes to Gibralt
U.S., Inc. (an affiliate of a director,  Samuel  Belzberg,  to which the Company
issued $1,100,000  principal amount notes) and to two directors (James A. Wylie,
Jr. and Peter  Norris,  to each of whom the  Company  issued  $50,000  principal
amount  of  notes).  The  Company  issued  these  notes  in  exchange  for  loan
commitments  made by  these  noteholders.  The  Company  also  issued  to  these
noteholders  Class D Preferred Stock as a prepaid discount to recognize that the
loan  commitments  were expected to be converted  into equity in a future equity
financing  transaction  that the Company then  contemplated,  and to reflect the
risk that the equity  financing  transaction  might not occur.  These  shares of
Class D Stock were  convertible  into a total of 120,863  shares of common stock
upon  satisfaction of certain  conditions.  The notes were  convertible into the
securities to be issued in the  contemplated  equity financing on the same terms
as applied to the other investors in the equity financing.

On August 22, 2003,  the Company  exchanged  the Class C Preferred  Stock for an
equal number of shares of Class E Preferred  Stock,  and  exchanged  the Class D
Preferred  Stock for an equal number of shares of Class F Preferred  Stock.  The
Company  exchanged  these  shares  of  preferred  stock in  accordance  with the
stipulation  of settlement it entered into to settle the Augenbaum  class action
lawsuit  that was filed in late July 2003.  That  lawsuit  claimed,  among other
things,  that the Class C Preferred  Stock and Class D  Preferred  Stock was not
permitted  to be, by its terms,  convertible  into  common  stock.  Accordingly,
although  the  Company  denied  the  allegations  in the  lawsuit,  to  reach  a
settlement amicably, the Company created the Class E and Class F Preferred Stock
and performed the preferred stock exchange. The Class E and F Preferred Stock is
not by its terms convertible into common stock. However, by a separate agreement
between the Company and the holders of the Class E and F Preferred  Stock,  upon
the satisfaction of certain conditions, the Company would issue 1,084,690 shares
of common  stock in  exchange  for the Class E  Preferred  Stock and would issue
120,863 shares of common stock in exchange for the Class F Preferred Stock.

On September 2, 2003,  the Company  entered into  definitive  agreements  for an
equity  financing.  Pursuant to these  agreements,  on  September  3, 2003,  the
investors  in the  equity  financing  funded  $6,500,000  in the form of secured
bridge  loans.  The  $1,200,000  principal  amount of Class D notes the  Company
issued in May 2003  converted  into  common  stock at the final  closing  of the
equity  financing on November 25, 2003. The secured bridge notes  converted into
common stock at $2.00 per share at the final  closing,  the investors  purchased
$15,500,000  of common stock for $2.50 per share and the  $1,200,000  in Class D
notes and accrued  interest on these notes were  purchased  for common stock for
$2.50 per share.

On September  3, 2003,  in  connection  with the equity  financing,  the Company
issued  securities to pay the fees of the placement agent that it had engaged in
April 2003 to assist in  obtaining  the  financing  that was needed.  In lieu of
paying this fee in cash, the Company  issued to the placement  agent $495,000 in
secured bridge notes plus warrants to purchase up to 1,635,163  shares of common
stock. Of these warrants,  701,663 warrants have an exercise price of $0.025 per
share,  247,500  warrants have an exercise  price of $2.00 per share and 686,000
warrants  have an  exercise  price  of  $2.50  per  share.  These  warrants  are
exercisable for five years.

On  November  25,  2003,  the  Company  held the  final  closing  of its  equity
financing,  pursuant to which the Company issued a total of 10,262,081 shares of
common  stock  to the  investors  in the  equity  financing.  (See  Note  14) In
connection  with the final  closing of the equity  financing,  the Company  also
exchanged  all  outstanding  Class E  Preferred  Stock for a total of  1,084,690
shares of common stock and exchanged all outstanding Class F Preferred Stock for
a total of 120,863  shares of common  stock,  as  provided  by the  August  2003
exchange  agreement.

Additionally,  the Company issued 20,000 shares of common stock to Verus Support
Services,  Inc. in  connection  with an agreement  entered into on September 30,
2003 to issue  these  shares  in lieu of  accrued  cash  payments  due under the
December 2001 agreement with Verus.

The Company  agreed to register the common stock issued in the equity  financing
and the common stock  underlying the warrants  issued to the placement agent for
resale to the public with the Securities Exchange  Commission,  and accordingly,
filed the resale  registration  statement  on December 3, 2003.  On February 10,
2004,  the  Company's  registration  statement  was  declared  effective  by the
Securities and Exchange Commission.

On December 3, 2003 and December 8, 2003, a total of 440,403 of the September 3,
2003 warrants  with an exercise  price of $0.025 per share were  exercised,  for
which the Company issued a total of 439,108 shares of common stock.  Because the
warrant holders used the cashless exercise feature of the warrants, they did not
have to pay the  exercise  price in cash and the Company  issued  fewer than the
total number of warrants exercised.

On December 18,  2003,  in  connection  with the equity  financing,  the Company
issued an additional  13,903 shares of common stock to those  investors who paid
cash for their shares at the final closing of the equity financing, as they were
entitled  to either  receive the  interest  that was earned on their funds while
held in escrow or to receive shares in lieu of this  interest,  as determined by
the placement  agent. At the placement  agent's  election,  the Company received
approximately  $35,000 in interest  from the escrow  agent on December 18, 2003,
and then issued the  additional  shares to the investors at a price of $2.50 per
share.

On November  25,  2003,  the number of  authorized  shares of Common  Stock were
increased from 80,000,000 to  500,000,000,  $0.001 par value, in order to enable
the issuance of shares in connection with the equity financing.

As of December 31, 2003, the Company had authorized 500,000,000 shares of common
stock,  $0.001 par value, of which 13,129,113 (giving effect to the 1:25 reverse
split effective June 17, 2004) shares were outstanding. The number of authorized
shares of common stock was later reduced to  50,000,000  in connection  with the
1:25 reverse split effective June 17, 2004.

On April 20, 2004, the Company  completed its offering to those persons who held
shares of its common stock as of August 29, 2003,  raising the approximate  $3.0
million  maximum in additional  equity  financing.  The targeted  offering,  for
1,188,470  shares of the Company's common stock at $2.50 per share (after giving
effect to the 1:25 reverse split effective June 17, 2004),  allowed stockholders
to purchase  one share of the  Company's  common  stock for each share of common
stock  held  on  August  29,  2003.  The  targeted  offering  also  included  an
"over-subscription  right" which  allowed  stockholders  to purchase  additional
shares to the extent the "basic rights" were not fully  subscribed.  The Company
filed a  registration  statement  to  register  the  shares to be offered to the
stockholders as of August 29, 2003 (the "targeted  offering").  The SEC declared
that registration statement effective on February 13, 2004.

On October 25, 2004, the Company completed the private placement equity and debt
financing  entered into on September 28, 2004 as discussed in Note 16, resulting
in  net  proceeds  of  approximately  $9.8  million.  In  connection  with  this
financing, the Company issued 2,362,420 shares of common stock and $7,000,000 in
convertible  debt,  along with  warrants to purchase up to  3,013,671  shares of
common  stock at an exercise  price of $2.10.  During  2004,  holders of 163,399
warrants  exercised  these  warrants,  at an exercise  price of $2.10 per share.
Accordingly,  the Company issued 163,399 shares of common stock to these warrant
holders and received  $343,138 in  aggregate  proceeds.  Subsequent  to year-end
2004,  the  holders of  $3,288,000  principal  amount of  debentures  elected to
convert these debentures  (including accrued interest of approximately  $31,108)
into  common  stock at $2.29 per  share,  and  accordingly  the  Company  issued
1,449,392 shares of common stock to these debenture holders. Also, subsequent to
year-end 2004, the holders of 192,811  warrants  exercised  their warrants at an
exercise price of $2.10 per share, and accordingly the Company received proceeds
of $404,903.

Additionally,  the  warrants  issued to the  placement  agent in the 2003 equity
financing  were  subject  to  an  anti-dilution  adjustment  for  future  equity
investments. This adjustment was triggered on October 25, 2004 and, as such, the
warrants  with  exercise  prices  of $2.00  were  adjusted  to $1.93  and  7,588
additional  warrants were issued, and the warrants with exercise prices of $2.50
were adjusted to $2.32 and 48,145 additional  warrants were issued.  Pursuant to
the  agreement  with the placement  agent,  on October 25, 2004 the Company also
issued  warrants to purchase an additional  73,539 shares of common stock, at an
exercise  price of $2.01  per  share,  because  the  Company  agreed  to pay the
placement  agent  commissions  for sales of  securities  within  one year of the
termination  of the  agreement  with  Sunrise  that  was made to  investors  who
participated  in the 2003 equity  financing.  During the year ended December 31,
2004, a total of 1,184,719 of the warrants  issued to this placement  agent,  as
adjusted for  anti-dilution  and  commission,  had been  exercised  and 938,123
shares were  issued.  Because the  placement  agent used the  cashless  exercise
feature of the warrants, they did not have to pay the exercise price in cash and
the Company issued fewer than the total number of warrants.

                                DECEMBER 31, 2004

Stock, $0.001 par value, of which 17,781,525 shares were outstanding.

(d) Stock Options

The  figures  below  are  adjusted  to give  effect  to the 1:25  reverse  split
effective June 17, 2004.

In November  1998 and May 2001,  the Company's  Board of Directors  approved the
1998  Incentive  Plan (the 1998 Plan) and the 2001 Stock  Option  Plan (the 2001
Plan) (collectively, the Plans), respectively,  permitting the granting of stock
options to employees,  directors,  consultants and advisors, which may be either
incentive stock options or nonqualified  options and stock awards. The Board had
reserved  30,000 and 70,000  shares of Common Stock for issuance  under the 1998
Plan and the 2001 Plan, respectively.

In November  2003,  the Company's  stockholders  approved the 2003 Omnibus Plan,
under which the Company  reserved  1,600,000  shares of common  stock for future
issuance.  The 2003 Omnibus Plan provides for grants or awards of stock options,
restricted  stock awards,  restricted  stock units,  performance  grants,  stock
awards,  and stock  appreciation  rights.  Only present and future employees and
outside directors and consultants are eligible to receive incentive awards under
the 2003 Omnibus Plan.

The exercise  price and vesting are  determined by the Board of Directors at the
date of grant.  Options  generally  vest over two to four  years,  and expire 10
years  after  the date of grant.  Incentive  stock  options  under the Plans are
granted at not less than fair market value per share of Common Stock on the date
of grant or 110% of fair market  value for any  stockholder  who holds more than
10% of the total combined voting power of all classes of stock of the Company.

As of December 31, 2004,  619,529  options and other incentive stock awards were
available for future grants under the 2003 Omnibus  Plans.  In addition,  27,076
options were  available  under the 1998 Plan and 23,732  options were  available
under the 2001 Plan as of December 31, 2004.

A summary of stock option activity is as follows:

(e) Issuance of Stock Options to Consultants

In fiscal 2003, the Company granted fully exercisable  options to purchase 2,565
shares of common  stock at  exercise  prices  per share in the range of $4.25 to
$11.00 to two  consultants  in  exchange  for  marketing  services.  The Company
recorded  the fair  value of such  options,  based on the  Black-Scholes  option
pricing  model,  as  stock-based  compensation  expense  totaling  $9,011 in the
statement of operations for year ended December 31, 2003.

In fiscal 2003, the Company  granted  options to purchase 4,000 shares of common
stock at an exercise  price per share of $11.50 to a service  provider for legal
services.  The Company  recorded  the fair value of such  options,  based on the
Black-Scholes option pricing model, as stock-based compensation expense totaling
$13,300 in the statement of operations for year ended December 31, 2003.

On  September 3, 2003,  the Company  acquired  rights to the EVLT Patent,  which
relates to the technology underlying the Company's EVLT(R) product line. As part
of the  transaction,  the Company  entered into an agreement with Dr. Robert Min
pursuant to which the Company  granted Dr. Min options to purchase 40,000 shares
of Common  Stock.  The Company  recorded the fair value of these  options in the
amount  of  $312,078  based  on  the  Black-Scholes  option  pricing  model  and
capitalized  this  cost as part of the  related  intangible  asset  that will be
amortized over the remaining life of the EVLT Patent.  The  amortization  of the
intangible  asset is being  recorded as a component of cost of goods sold.  (See
Note 15)

In fiscal year 2004, the Company  granted  options to purchase  32,672 shares of
common  stock at  exercise  prices  per  share in the range of $2.02 to $6.75 in
exchange for services. The Company recorded the fair value of such options based
on the Black-Scholes  option pricing model, as stock-based  compensation expense
totaling  $79,449 in the  statement of  operations  for year ended  December 31,
2004.

10) SEGMENT REPORTING

The Company  follows SFAS No. 131,  Disclosures  about Segments of an Enterprise
and Related Information,  which establishes  standards for reporting information
regarding  operating  segments  in  annual  financial  statements  and  requires
selected  information  for those  segments to be presented in interim  financial
reports  issued to  stockholders.  SFAS No. 131 also  establishes  standards for
related disclosures about products and services and geographic areas.

Operating  segments are  identified as  components of an enterprise  about which
separate discrete financial information is available for evaluation by the chief
operating  decision maker, or decision making group, in making  decisions on how
to allocate  resources  and assess  performance.  The Company's  chief  decision
making  group,  as  defined  under SFAS No.  131,  is the  Executive  Management
Committee.

The Company's  reportable segments are determined by product type: laser systems
and fibers, accessories and service. The accounting policies of the segments are
the  same as  those  described  in Note 2. The  Executive  Management  Committee
evaluates segment  performance based on revenue.  Accordingly,  all expenses are
considered  corporate level activities and are not allocated to segments.  Also,
the Executive Management Committee does not assign assets to its segments.

This table presents revenues by reportable segment:

11) OTHER COMMITTMENTS

(a) Leases

The Company leases certain equipment and office  facilities under  noncancelable
operating and capital  leases that expire at various  dates  through  2014.  The
Company's  building  lease at its  subsidiary in the United Kingdom is a 25-year
lease  through 2024.  However,  the Company has an option,  at its election,  to
terminate the lease  agreement  after 15 years in 2014 and again in 5 more years
in 2019.  If the  Company  chooses  not to  exercise  these  options,  the lease
agreement  continues  for the  remaining  years  through  2024.  The Company has
elected to sublease a portion of the UK Facility.  Subsequent  to year-end,  the
Company  renewed  the U.S.  headquarters  lease and  expanded  the leased  space
through February 2008. Total rent expense under these operating lease agreements
for the years  ended  December  31,  2004 and 2003 net of  sublease  income  was
$524,160, and $476,585, respectively.

Future minimum  payments  required under these operating  leases at December 31,
2004 are as follows:

(b) Litigation

From  time to  time,  the  Company  is  involved  in  legal  and  administrative
proceedings  and claims of  various  types.  While any  litigation  contains  an
element of uncertainty,  management,  in consultation with the Company's general
counsel,  presently  believes that the outcome of each such other proceedings or
claims  which are pending or known to be  threatened,  or all of them  combined,
will not have a material adverse effect on the Company.

(c) Employment Agreement with Certain Officers

Effective  December 28, 2003, the Company  entered into an employment  agreement
with James A. Wylie, Jr. the Company's chief executive  officer.  This agreement
supercedes the Company's  January 10, 2003 employment  agreement with Mr. Wylie,
and extends his employment by one year from December 31, 2004 until December 31,
2005.  The December 28, 2003  employment  agreement  provides for an annual base
salary of $330,000 (commencing January 1, 2004), an award of options to purchase
up to 108,000 shares of common stock and certain bonus  compensation.  Effective
February 15, 2005, the terms of Mr. Wylie's  employment  agreement were modified
by (i) extending the term of employment  through December 31, 2007 for an annual
base salary of $355,000,  (ii) providing that in the event of termination by the
Company  without cause or by Mr. Wylie for good reason,  the Company will pay an
amount equal to either his base compensation for the remainder of the term or 12
months, whichever is greater and (iii) clarifying that Mr. Wylie will be able to
terminate  his  employment  agreement  upon not less  than 90 days'  notice  for
reasons  other than good reason,  in which case the Company will not be required
to pay severance.

David Swank became a director in March 2003 and served on the Audit Committee of
the Company's  Board of Directors from that time until  September 1, 2003,  when
the Company  appointed  Mr. Swank as chief  financial  officer,  on a consulting
basis.  The Company's  agreement with Mr. Swank provided for six month renewable
terms,   commencing   September  3,  2003.  Mr.  Swank's  current  monthly  base
compensation  is $16,700.  Effective  February 15, 2005, the Company amended its
agreement  with  Mr.  Swank by (i)  extending  the  term of  employment  through
December 31, 2005,  and (ii) providing Mr. Swank with severance pay in the event
of termination  without cause,  equal to the lesser of Mr. Swank's  compensation
for the 12 months or for the balance of the then-current  term of his agreement,
subject  to  compliance  with  certain   non-competition  and   non-solicitation
obligations.

subsidiary in the U.K.,  in February  2000.  Mr.  Stearn's  current  annual base

of Mr.  Stearn's  employment by providing  Mr. Stearn with  severance pay in the
event of termination  without cause, equal to 12 months base salary,  subject to
compliance with certain non-competition and non-solicitation obligations.

John Welch became vice president, North American marketing, in October 2002. Mr.

Company amended the terms of Mr. Welch's  employment by providing Mr. Welch with
severance pay in the event of termination without cause, equal to 12 months base
salary, subject to compliance with certain  non-competition and non-solicitation

(d) Other

During 2004, the Company filed  lawsuits in the United States  Federal  District
Court  for the  District  of  Massachusetts  against  four  competitors  seeking
injunctive  relief and damages for  infringement  of the Company's  U.S.  Patent
Number  6,398,777  covering the  endovascular  laser treatment of varicose veins
which the Company uses in its EVLT(R)  product line.  If the  Company's  EVLT(R)
patent is judicially  determined to be invalid,  the Company will not prevail in
the  infringement  actions and will not be able to exclude  third  parties  from
using the Company's EVLT(R)  technology.  As a result, the EVLT(R) patent may be
determined  to be  impaired  and the  Company's  EVLT(R)  revenue  stream may be
adversely affected.

(12) MERGER AND PRIVATE OFFERING OF COMMON STOCK

The Company is a  corporation  originally  formed under the laws of the State of
Nevada on March 3, 1998 under the name  Natexco  Corporation.  On  February  11,
2002, the Company changed its name from Natexco  Corporation to Diomed Holdings,
Inc. On February 14, 2002, the Company acquired Diomed, Inc. in a merger.  Under
the terms of the merger,  the  Company  issued  Class A  Preferred  Stock to the
former stockholders of Diomed, Inc. These shares of Class A Preferred Stock have
since converted into Common Stock, and no Class A Stock remains outstanding.  As
a result of the merger,  Diomed,  Inc.  became a wholly-owned  subsidiary of the
Company.  The merger was accounted for as a recapitalization.  Accordingly,  the
historical records of Diomed, Inc. became the historical records of Natexco and,
after the merger,  the Company.  After the merger, the business conducted by the
Company was the business conducted by Diomed, Inc. prior to the merger.

Concurrently with the merger,  the Company issued 200,000 shares of Common Stock
in a private placement offering at a price of $50.00 per share (amounts adjusted
to reflect the 1:25 reverse split  effective June 17, 2004),  resulting in gross
proceeds to the Company of  $10,000,000  from the private  offering.  The common
stock issued in this private offering were not subject to refund,  redemption or
rescission  and,  accordingly,  were  included as a component  of  stockholders'
equity,  net of applicable  costs.  The Company  registered the shares of Common
Stock issued in the private  offering with the SEC in a  registration  statement
that the SEC declared effective on October 24, 2002.

After the merger,  the board of directors of the Company  determined that it was
in the best  interests  of the Company and its  stockholders  for the Company to
change its state of  incorporation  from Nevada to  Delaware.  On May 13,  2002,
after obtaining  stockholder  approval,  the  reincorporation  was effected by a
migratory merger, and the Company is now a Delaware corporation.

The Merger  was  accounted  for as a  recapitalization.  Costs of  approximately
$2,100,000  related  to the  issuance  of the  Company's  shares in the  private
placement  financing and to its preparation and negotiation of the documentation
for the  Merger  were paid by the  Company.  These  costs  were  offset  against
paid-in-capital within stockholders equity in the year ended December 31, 2002.

(13) EXCHANGE OF CLASS C AND CLASS D CONVERTIBLE PREFERRED

On July 28,  2003,  the  Company  was  named as a  defendant  in a class  action
lawsuit,  Augenbaum  v. Diomed  Holdings,  Inc.  On August 6, 2003,  the Company
entered into a stipulation of settlement to resolve this suit.  The  stipulation
of settlement became final on October 15, 2003.

In  connection  with the  stipulation  of  settlement,  on August 22, 2003,  the
Company  entered  into an  agreement  with the  holders of the Class C Preferred
Stock by which the holders  tendered all 20 shares of Class C Preferred Stock in
exchange  for an equal  number  of shares of Class E  Preferred  Stock,  and the
Company  entered  into an  agreement  with the  holders of the Class D Preferred
Stock by which the holders tendered all 24 shares of Class D Preferred Stock for
an equal  number of shares of Class F  Preferred  Stock.  The Class E  Preferred
Stock and the Class F Preferred Stock entitle the holders to one vote per share.
Following  the exchange of Class C Preferred  Stock for Class E Preferred  Stock
and  Class D  Preferred  Stock  for Class F  Preferred  Stock,  both the Class C
Preferred Stock and Class D Preferred Stock were eliminated.

Following  stockholder  approval of the issuance of shares of Common Stock to be
issued in exchange for the Class E Preferred Stock and Class F Preferred  Stock,
the Company had the right to purchase  from the holders of the Class E Preferred
Stock,  and the holders of the Class E Preferred  Stock were  obligated to sell,
all 20 shares of Class E Preferred  Stock in exchange  for  1,084,690  shares of
Common Stock,  and the Company had the right to purchase from the holders of the
Class F Preferred  Stock,  and the  holders of the Class F Preferred  Stock were
obligated  to sell,  all 24 shares of Class F Preferred  Stock in  exchange  for
120,863  shares  of  Common  Stock.  Upon  a  sale,  lease,  exchange  or  other
disposition of all or substantially all of the Company's assets,  the holders of
the Class E Preferred  Stock and Class F Preferred Stock had the right to tender
all shares of their preferred stock in exchange for the corresponding numbers of
shares of Common Stock noted above.

Shares of Class E Preferred  Stock and Class F Preferred Stock were preferred in
liquidation to the extent that before any  distribution  was made to the holders
of Common  Stock,  there must be a  distribution  to the  holders of the Class E
Preferred  Stock in the amount of $108,469 per share of Class E Preferred  Stock
and a distribution  to the holders of the Class F Preferred  Stock in the amount
of $10,072 per share of Class F  Preferred  Stock.  The holders of Common  Stock
share pro rata in the remainder of the net liquidation proceeds. On November 25,
2003, in connection with the final closing of the equity financing  discussed in
Note 14, the Company  exchanged all  outstanding  Class E Preferred  Stock for a
total of 1,084,690 shares of common stock and exchanged all outstanding  Class F
Preferred  Stock for a total of 120,863  shares of common stock,  as provided by
the August 2003 exchange agreement.

(14) PRIVATE PLACEMENT EQUITY FINANCING ENTERED INTO SEPTEMBER 2, 2003

On  September  2, 2003,  the Company  entered  into a private  placement  equity
financing  transaction  with accredited  investors who agreed to purchase common
stock  for an  aggregate  purchase  price  of  $23,200,000.  The  terms  of this
transaction provided that the equity financing would occur at two closings.  The
first closing  occurred on September 3, 2003. At that time, the investors funded
$6,500,000 in cash to the Company in exchange for $6,500,000 principal amount of
secured  convertible  bridge notes.  At the second closing on November 25, 2003,
the $6,500,000 principal amount of notes was converted into a total of 3,250,000
shares  of  common  stock  at a  conversion  price of $2.00  per  share  and the
investors invested the remaining $16,700,000 of the equity financing in exchange
for common stock at a purchase price of $2.50 per share.

The investors  who  participated  in the first  closing of the equity  financing
included the four holders of the Company's  $2,000,000 principal amount of Class
E Secured Notes due 2006,  which the Company issued in connection  with a bridge
financing transaction in December 2002. At the first closing,  these noteholders
invested an aggregate of $2,000,000.  These  noteholders  were (i) Gibralt U.S.,
Inc., an affiliate of one of the Company's  former  directors,  Samuel Belzberg,
which  held  $1,500,000  of the Class E Notes and  purchased  $1,500,000  of the
secured bridge notes,  (ii) Morris Belzberg,  a cousin of Samuel  Belzberg,  who
held $300,000 of the Class E Notes and purchased  $300,000 of the secured bridge
notes,  (iii)  Charles  Diamond,  who held  $100,000  of the  Class E Notes  and
purchased $100,000 of the secured bridge notes and (iv) Steven  Schraiberg,  who
held $100,000 of the Class E Notes and purchased  $100,000 of the secured bridge
notes.  At the time of the first closing,  the Company repaid all of the Class E

Of the  $16,700,000  invested  at the second  closing  of the equity  financing,
$15,500,000  was paid by the investors in cash.  The Company also  converted the
Class D Secured Notes due 2004,  which were issued in  connection  with a bridge
financing transaction in May 2003, for the remaining $1,200,000 of common stock.
The  holders  of the  Class D Notes  were,  at the time of the May  2003  bridge
financing,  directors,  or affiliates of directors.  These three Class D holders
are Gibralt U.S.,  Inc., which is an affiliate of Samuel Belzberg (the holder of
$1,100,000  in  principal  amount of Class D Notes);  James A.  Wylie,  Jr. (the
holder of $50,000 in principal  amount of Class D Notes);  and Peter Norris (the
holder of $50,000 principal amount of Class D Notes). The Company issued a total
of  10,259,921  shares  of  common  stock to the 119  investors  (including  the
placement  agent and the holders of the Class D Notes) on  November  25, 2003 at
the final closing of the equity  financing,  including  499,294 shares that were
issued on conversion of the Class D Notes.

In connection with the Equity Financing, the Company issued warrants to purchase
up to 1,635,163 shares of Common Stock to its placement agent, including 701,663
warrants at an exercise price of $0.025,  247,500  warrants at an exercise price
of $2.00 and 686,000 warrants at an exercise price of $2.50. The warrants issued
to the placement agent are exercisable for five years beginning upon approval by
stockholders of the Equity Financing at the annual meeting.  The placement agent
also participated as an investor in the Equity Financing by reinvesting $495,000
of its fee in exchange for Secured Bridge Notes  convertible into 247,500 shares
of Common Stock.  The original  agreement with the placement agent provided that
the  Company  pay the  placement  agent a cash fee  equal to 10% of the funds it
raised in a  financing  and issue to the  placement  agent  warrants to purchase
shares of Common Stock equal to 10% of the aggregate  number of shares of Common
Stock that were purchased by the Investors in the Equity Financing.

As of September 3, 2003, the agreement with the placement agent had been amended
to raise the maximum amount of the financing  approved by the board of directors
to  $23,200,000  and to provide for the deposit of all of the  Investors'  funds
into an escrow pending the second  closing.  The Company  further agreed that it
would pay the cash portion of the fee due to the  placement  agent in connection
with the Equity Financing in securities rather than in cash. The placement agent
agreed to reinvest its  financing  fee,  and the parties  agreed that they would
calculate  the  financing  fee on the  total  amount  invested  in the  Company,
exclusive  of amounts to be invested by the holders of the Class D notes and the
Class E notes, but inclusive of the amount the placement agent reinvested.

As of December  31,  2003,  the Company  incurred  approximately  $3,650,000  in
placement agent,  legal and other fees in connection with the Equity  Financing,
including  $1,798,579 in non-cash  charges and $1,851,000 in cash-based fees. In
connection with the first closing,  the Company  incurred  $651,923 in placement
agent and legal fees,  including the fee due to be paid in cash to the placement
agent in the amount of $495,000 that the placement agent invested in the Secured
Bridge Notes.  These costs were capitalized as deferred financing costs and were
being  amortized to general  interest  expense over the life of the notes,  such
that the full amount of costs was  amortized by the earlier of the maturity date
of the notes or by the month the notes were converted  into equity.  In the year
ended December 31, 2003,  the Company  recognized  $651,923 in general  interest
expense  pertaining to this  amortization of the deferred  financing  costs, and
accordingly,  the  balance  of the  deferred  financing  costs  were  zero as of
December 31, 2003.

In  connection  with the first  closing,  the Company  recognized  an additional
placement agent fee, in the amount of $1,798,579, for 247,500 warrants issued to
a placement  agent.  The warrant fee was recorded as a deferred  financing  cost
upon  favorable  stockholder  approval of the Equity  Financing  on November 25,
2003, and was fully amortized to general interest expense in the period in which
the Secured Bridge Notes converted to equity,  with a corresponding  increase in
additional paid in capital. The net impact on stockholders' equity was zero when
the net loss,  including the deferred financing cost, was fully reflected in the
accumulated deficit.

In  connection  with the second  closing,  the  Company  incurred  approximately
$1,200,000 in legal and other fees through  December 31, 2003.  These costs were
capitalized  as deferred  offering  costs and were recorded as an offset against
additional paid in capital in stockholders  equity upon completion of the second
closing of the Equity Financing.

                                DECEMBER 31, 2004

The Company  entered into a  registration  rights  agreement  providing  for the
Company to register  with the  Securities  and  Exchange  Commission  the shares
purchased by the investors and the shares  underlying the warrants issued to the
placement  agent for resale to the public.  The  registration  rights  agreement
required the Company to file a registration  statement for these shares within 5
days after the completion of the Equity  Financing,  and accordingly the Company
filed the resale  registration  statement  on December 3, 2003.  On February 10,
2004,  the  Company's  registration  statement  was  declared  effective  by the
Securities and Exchange Commission.

(15) ACQUISITION OF EXCLUSIVE EVLT(R) TECHNOLOGY

On September 3, 2003, the Company  acquired  exclusive rights to U.S. Patent No.
6,398,777 and related  foreign  patents and patent  applications  for endovenous
laser  treatment  of varicose  veins.  These  patents  relate to the  technology
underlying the Company's EVLT(R) procedure.  This acquisition  resulted from two
transactions.

In the first  transaction,  the Company  purchased  the  interest in the EVLT(R)
patent  owned by one of its five  named  inventors,  Dr.  Robert  J.  Min.  This
transaction was completed under a purchase agreement between the Company and Dr.
Min entered  into on July 23, 2003,  after the  satisfaction  of the  conditions
precedent to the closing of the purchase  agreement.  On September 3, 2003,  the
Company  paid the  purchase  price of  $500,000  in cash and  issued  options to
purchase  40,000  (adjusted to give effect to the 1:25 reverse  split  effective
June 17, 2004) shares of common  stock in exchange for Dr. Min's  assignment  to
the Company of his  interest in the EVLT(R)  patent.  The Company also agreed to
pay to Dr. Min variable  payments based on the Company's future sales of EVLT(R)
products.  Dr. Min had previously licensed the EVLT(R) patent to the Company and
had served as a consultant to Diomed.  Dr. Min is expected to continue to act as
a consultant to Diomed under a consulting agreement.

In the second  transaction,  the Company  licensed,  on an exclusive  basis, the
EVLT(R) patent from Endolaser  Associates,  LLC, the assignee of interest in the
EVLT(R)  patent  from the other  four  named  inventors.  This  transaction  was
completed under a license agreement between the Company and Endolaser Associates
entered  into on  July  11,  2003,  after  the  satisfaction  of the  conditions
precedent to the taking effect of the license  agreement.  On September 3, 2003,
the Company paid  Endolaser  Associates  $1,500,000  in cash in exchange for the
exclusive  license  granted  by  Endolaser  Associates.  The  Company is to make
additional payments totaling $2,500,000 in 10 quarterly installments of $250,000
each,  commencing in the fourth  quarter of 2003,  and  accordingly  the Company
recorded a liability in the amount of $2,500,000  net of a $254,000  discount to
reflect imputed  interest based on an interest rate of 8%. The discount is being
amortized to general interest expense over the period of the technology payable.
On December 1, 2003,  subsequent  to  completion  of the equity  financing,  the
Company paid Endolaser  Associates the first quarterly  installment of $250,000.
The Company also made four quarterly  installment payments during the year ended
December 31, 2004,  and continued to amortize the discount to interest  expense.
Accordingly,  at December 31, 2004, the balance  remaining was $1,178,000 net of
debt  discount.  The Company  agreed with  Endolaser  Associates to pay variable
royalties based on sales of EVLT(R) products.

In 2003, the Company  recorded an intangible  technology  asset in the amount of
$4,702,000 to record the acquisition of the EVLT Patent. The intangible asset is
being amortized over the remaining 16-year life of the EVLT Patent.

(16) PRIVATE PLACEMENT EQUITY AND DEBT FINANCING ENTERED INTO SEPTEMBER 28, 2004

On September 28, 2004, the Company  entered into  definitive  agreements for the
sale and  issuance  of  convertible  debentures,  common  stock and  warrants to
purchase  common stock to certain  accredited  investors in a private  placement
financing transaction. On October 25, 2004, after receiving approval to list the
shares from the AMEX, the Company completed this  transaction,  and received net
proceeds of  approximately  $9.8 million before  related legal and  registration
expenses of  approximately  $300,000.  The  Company  will use the  proceeds  for
general working capital purposes.

The following summarizes the principal terms of the transaction:


                                      F-32


                              DIOMED HOLDINGS, INC.
              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                DECEMBER 31, 2004

Variable Rate Convertible Debentures

The Company  issued an aggregate of $7,000,000  principal  amount of convertible
debentures at par. The convertible  debentures bear interest (payable  quarterly
in arrears on March 31, June 30,  September  30 and  December  31) at a variable
rate of 400 basis  points  over  six-month  LIBOR and mature four years from the
date of issuance.

The debentures are  convertible at any time at the option of the holder into the
Company's common stock at a conversion price of $2.29 per share,  which was 120%
of the $1.91  per share  closing  price of the  common  stock on the AMEX on the
trading  day prior to the date that the  Company  and the  investors  signed the
definitive  purchase  agreements  The  conversion  price is  subject  to certain
adjustments,  with a minimum  conversion  price of $2.20 per  share,  unless the
Company obtains stockholder approval to reduce the conversion price below $2.20.

Subject to certain  conditions,  the debentures  will also be convertible at the
Company's option at any time after the first anniversary of the issuance date if
the closing  price of the  Company's  common stock equals or exceeds 175% of the
conversion  price for at least 20  consecutive  trading  days.  Also  subject to
certain conditions,  upon maturity, the Company may cause the holders to convert
the entire  principal  amount of  debentures  outstanding  into shares of common
stock at a price per share  equal to the lesser of the stated  conversion  price
and 90% of the volume weighted average trading price of its common stock for the
20 days prior to the maturity date.

After the first year and at the Company's option, subject to certain conditions,
interest  may be paid in  shares  of its  common  stock  in lieu of  cash,  at a
conversion price which is based on the closing prices of the common stock on the
fifth  through  first trading days  immediately  preceding the interest  payment
date. The conversion  rate for interest will be discounted by 10% if the Company
obtains stockholder  approval of this discount.  In any event,  though,  without
stockholder  approval,  the  conversion  rate for interest will not be less than
$1.91,  the  closing  price of the common  stock on the AMEX on the  trading day
prior to the date that the  Company  and the  investors  signed  the  definitive
purchase agreements.

Subsequent  to year-end  2004,  the holders of  $3,288,000  principal  amount of
debentures  elected to convert  that  amount of  debentures  (including  accrued
interest  of  approximately  $31,108)  into  common  stock at $2.29  per  share.
Accordingly,  the  Company  issued  1,449,392  shares of  common  stock to these
debenture holders.

Common Stock

The  Company  issued  and  sold,  for  an  aggregate  gross  purchase  price  of
$3,614,503,  shares of its common stock at a purchase  price of $1.53 per share,
which is 80% of the closing price of the common stock on the AMEX on the trading
day prior to the date that the Company and the investors  signed the  definitive
purchase agreements. Accordingly, the Company issued a total of 2,362,420 shares
of its  common  stock  to the  investors  who  purchased  common  stock  in this
transaction.

Warrants to Purchase Common Stock

In  connection  with the October  2004  private  placement,  the Company  issued
warrants to purchase up to 1,832,461 shares of common stock to the investors who
purchased  convertible  debentures  and  warrants to  purchase  up to  1,181,210
additional  shares of common stock to the investors who purchased  common stock.
The  warrants  are  exercisable  for five years from the date of  issuance at an
exercise price of $2.10 per share,  which is 110% of the $1.91 per share closing
price of the common  stock on the AMEX on the trading day prior to the date that
the Company and the investors  signed the definitive  purchase  agreements.  The
exercise  price is subject to certain  adjustments,  including  future  sales of
securities below the exercise price,  with a minimum exercise price of $1.91 per
share,  unless the Company obtains  stockholder  approval to reduce the exercise
price below $1.91.

During  2004,  holders of  163,399  warrants  exercised  these  warrants,  at an
exercise  price of $2.10 per share.  Accordingly,  the  Company  issued  163,399
shares of  common  stock to these  warrant  holders  and  received  $343,138  in
aggregate proceeds.

Subsequent to year-end 2004,  the holders of 192,811  warrants  exercised  these
warrants,  at an  exercise  price of $2.29 per share.  Accordingly,  the Company
issued  192,811  shares of common  stock to these  warrant  holders and received
$404,903 in aggregate proceeds.

The  Company  recognized  the  $2,261,399  fair  value of the  warrants  and the
beneficial  conversion  feature related to the immediate  convertibility  of the
notes to equity,  as a discount to the notes,  with a corresponding  increase in
additional paid-in capital. The value ascribed to the warrants was approximately
$1,711,399 using the  Black-Scholes  option pricing model and the value ascribed
to the beneficial conversion feature of the notes was $550,000.  The discount is
being  amortized  over the term of the notes to non-cash  interest  expense such
that the full amount of the  discount  will be  amortized  by the earlier of the
maturity  date of the notes or the  conversion  of the notes to equity.  The net
impact to  stockholders'  equity will be zero when the net loss,  including  the
amortization  of the  discount,  is  fully  reflected  in  accumulated  deficit.
Accordingly,  the notes were recorded at $4,738,601, net of the debt discount of
$2,261,399.  For the year ended  December 31, 2004,  $78,248 was  recognized  in
non-cash interest expense pertaining to this discount.

                                DECEMBER 31, 2004

In connection with the financing,  the Company incurred approximately $1,100,000
in  commissions,  legal,  accounting  and  registration  fees.  These costs were
allocated   between  the  debt  and  equity   components  of  the   transaction.
Accordingly, $730,000 allocated to the debt portion was capitalized and is being
amortized  to interest  expense  over the life of the notes,  such that the full
amount of the costs will be amortized by the earlier of the maturity date of the
notes,  or by the month the notes are  converted  to equity.  For the year ended
December 31, 2004,  $30,000 was  recognized  in interest  expense  pertaining to
these costs.  Additionally,  $300,000 was allocated to the equity  component and
offset in equity against the proceeds received from the financing.

Registration of Common Stock

The Company agreed to undertake  registration  with the Commission of the common
stock and common stock underlying the convertible  debentures and warrants.  The
Company  filed  the  registration  statement  on  November  24,  2004,  and  the
Commission declared this registration statement effective on December 6, 2004.

(1) OPERATIONS

Diomed Holdings, Inc. ("Diomed" or "the Company") develops and commercializes
minimally invasive medical procedures that employ its laser technologies and
associated disposable products. Using its proprietary technology, including its
exclusive rights to U.S. Patent No. 6,398,777, the Company currently focuses on
endovenous laser treatment (EVLT(R)) of varicose veins. The Company also
develops and markets lasers and disposable products for photodynamic therapy
(PDT) cancer procedures and products for other clinical applications, including
dental and general surgical procedures.

In developing and marketing its clinical solutions, the Company uses proprietary
technology and aims to secure strong commercial advantages over competitors by
gaining governmental approvals in advance of others, by developing and offering
innovative practice enhancement programs including physician training and
promotional materials, and by obtaining exclusive commercial arrangements. To
optimize revenues, Diomed focuses on clinical procedures that generate revenues
from both capital equipment and disposable products, such as procedure kits and
optical fibers.

Diomed's high power semiconductor diode lasers combine clinical efficacy,
operational efficiency and cost effectiveness in a versatile, compact,
lightweight, easy-to-use and easy-to-maintain system. Along with lasers and
single-use procedure kits for EVLT(R), the Company provides its customers with
state of the art physician training and practice development support. The
EVLT(R) procedure and the Company's related products were cleared by the United
States FDA in January of 2002.

be expected for the year. These interim financial statements have been prepared
in accordance with the instructions for Form 10-QSB, and therefore, do not
include all information and footnotes necessary for a complete presentation of
operations, financial position, and cash flows of the Company in conformity with
accounting principles generally accepted in the United States. The Company filed
with the Securities and Exchange Commission its 2004 annual report on Form
10-KSB on March 30, 2005, which included audited consolidated financial
statements for the year ended December 31, 2004 and information and footnotes
necessary for such presentation. These unaudited consolidated financial
statements should be read in conjunction with the audited consolidated financial
statements and the notes thereto included in our annual report on Form 10-KSB
for the year ended December 31, 2004.

(3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our Annual Report on Form 10-KSB for the year ended December 31, 2004 includes a
comprehensive summary of the significant accounting policies and methods used in
the preparation of our consolidated financial statements. The application of
these policies has a significant impact on our reported results. In addition,
the application of some of these policies depends on management's judgment, with
financial reporting results relying on estimations and assumptions about the
effect of matters that are inherently uncertain. For all of these policies,
management cautions that future events rarely develop exactly as forecast and
the best estimates routinely require adjustment.

Short-term Investments

Marketable debt and equity securities with original maturities greater than
three months are classified as short-term investments. Investments designated as
short-term consist of U.S. agency discount notes and corporate bonds, are
classified as available-for-sale, and are reported at fair value using the
specific identification method. Unrealized gains and losses, net of related tax
effects are reflected in other comprehensive income (loss) until realized.

Interest Expense and Other Financing Costs

The Company has issued options and warrants to non-employees from time to time
as payment for services. In all of these cases, the Company applies the
principles of SFAS No. 123 "Accounting for Stock-based Compensation" to value
these awards, which inherently include a number of estimates and assumptions
including stock price volatility factors. In addition to interest expense, the
Company records financing and certain offering costs associated with its capital
raising efforts in its statements of operations. These include amortization of
debt issue costs such as cash, warrants and other securities issued to finders
and placement agents, and amortization of debt discount created by in-the-money
conversion features on convertible debt accounted for in accordance with
Emerging Issues Task Force ("EITF") Issue 98-5, "Accounting for Convertible
Securities with Beneficial Conversion Features or Contingently Adjustable
Conversion Ratios," and Issue 00-27, "Application of Issue 98-5 to Certain
Convertible Instruments," by other securities issued in connection with debt as
a result of allocating the proceeds amongst the securities in accordance with
Accounting Principles Board ("APB") Opinion No. 14, "Accounting for Convertible
Debt and Debt Issued with Stock Purchase Warrants", based on their relative fair
values. The Company based the estimates and assumptions on the best information
available at the time of valuation, however, changes in these estimates and
assumptions could have a material effect on the valuation of the underlying
instruments.

(c) ACCOUNTING FOR STOCK-BASED COMPENSATION

The Company accounts for its employee stock-based compensation plans under
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees utilizing the intrinsic value method. Accordingly, compensation cost
for stock options issued to employees is measured as the excess, if any, of the
market price over the exercise price of the Company's stock at the date of the
fixed grant. Statement of Financial Accounting Standards ("SFAS") No. 123,
Accounting for Stock-Based Compensation, as amended by SFAS No. 148, establishes
a fair value-based method of accounting for stock-based compensation plans. The
Company has adopted the disclosure-only alternative under SFAS No. 123, with
respect to its employee stock compensation plan, which requires disclosure of
the proforma effects on net loss and loss per share as if SFAS No. 123 had been
adopted as well as certain other information.

(d) COMPREHENSIVE INCOME

SFAS No. 130, Reporting Comprehensive Income, requires disclosure of all
components of comprehensive income (loss). Comprehensive income is defined as
the change in stockholders' equity of a business enterprise during a period from
transactions and other events and circumstances from non-owner sources.
Comprehensive net loss for all periods presented is as follows:

equity.

Marketable securities, at September 30, 2005, all of which mature within one
year, consist of the following:


                                  Amortized Cost     Fair Value

                                   (UNAUDITED)

(f) NET LOSS PER SHARE

Net loss per share is computed based on the guidance of SFAS No. 128, Earnings
per Share. SFAS No. 128 requires companies to report both basic loss per share,
which is based on the weighted average number of common shares outstanding, and
diluted loss per share, which is based on the weighted average number of common
shares outstanding and the dilutive potential common shares outstanding using
the treasury stock method. The calculation of net loss applicable to common
stockholders for the three month and nine month periods ended September 30, 2005
includes $763,000 in non-cash dividends accreted on preferred stock as a result
of the beneficial conversion feature and the fair value adjustment to present
preferred stock at its exchangeable value related to the September 30, 2005
Private Placement.

As a result of the losses incurred by the Company for the three and nine month
periods ended September 30, 2005 and 2004, respectively, all potential common
shares were antidilutive and were excluded from the diluted net loss per share
calculations. The following table summarizes securities outstanding as of each
of the periods, which were not included in the calculation of diluted net loss
per share since their inclusion would be antidilutive.

(5) STOCK OPTIONS

(a) In November 2003, the Company's stockholders approved the 2003 Omnibus Plan,
under which the Company reserved 1,600,000 shares of common stock for future
issuance. In May 2005, the Company's stockholders approved an increase of
1,500,000 reserved shares providing for a total of 3,100,000 shares of common
stock reserved for future issuance. The 2003 Omnibus Plan provides for grants or
awards of stock options, restricted stock awards, restricted stock units,
performance grants, stock awards, and stock appreciation rights. Only present
and future employees and outside directors and consultants are eligible to
receive incentive awards under the 2003 Omnibus Plan.

The exercise price and vesting are determined by the Board of Directors at the
date of grant. Options generally vest over two to four years, and expire 10
years after the date of grant. Incentive stock options under the Plans are
granted at not less than fair market value per share of Common Stock on the date
of grant, or 110% of fair market value for any stockholder who holds more than
10% of the total combined voting power of all classes of stock of the Company.

As of September 30, 2005, 1,526,818 options and other incentive stock awards
were available for future grants under the 2003 Omnibus Plan. In addition, 2,542
options were available under the 2001 Plan as of September 30, 2005.

A summary of stock option activity for the 2003 Omnibus Plan, the 2001 Plan and
the 1998 Plan is as follows:

(6) DISTRIBUTION AGREEMENT WITH LUMINETX CORPORATION

On August 5, 2005, the Company entered into a distribution agreement with
Luminetx Corporation ("Luminetx"), pursuant to which Luminetx appointed Diomed
as a distributor and granted Diomed an exclusive right to distribute and sell
Luminetx' patented biomedical imaging system known as the VeinViewer(TM) Imaging
System. The agreement is for an initial term of three years following the
initial date that Luminetx delivers the VeinViewer(TM) product to Diomed, which
is expected to occur on or before January 31, 2006. The specific market covered
by this agreement includes those physicians who perform sclerotherapy,
phlebectomies or varicose vein treatments, initially in the United States and
the United Kingdom, with additional territories to be negotiated as
VeinViewer(TM) receives regulatory clearance in other countries, on terms to be
agreed. The Company loaned $500,000 to Luminetx on August 5, 2005, and the
Company will invest an additional $500,000 in Luminetx when Luminetx delivers to
the Company a minimum number of VeinViewer(TM) systems, as specified in the
distribution agreement. The note matures on August 5, 2006, bears interest at 5%
per annum and is convertible into Luminetx's common or preferred stock if
Luminetx completes an arms-length stock financing with a minimum of $3,000,000
raised or upon a change of control of Luminetx.

The Company also issued warrants to purchase up to 600,000 shares of our common
stock. The warrants have an exercise price of $2.90 per share, become
exercisable when the underlying shares are listed with the American Stock
Exchange and cease to be exercisable on the earlier of five years from full
vesting, August 5, 2011 and the date of termination of the Distribution
Agreement. The warrant is exercisable as to 50% of the underlying shares, with
the remainder becoming exercisable when Luminetx has both (A) produced at least
100 units of the system and (B) Diomed shall have accepted delivery of at least
25 units of the system.

In accordance with Emerging Issues Task Force Number 96-18 "Accounting for
Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling, Goods or Services", the fair value of the distribution
rights of $332,630 is being amortized over the 3 year period of the distribution
agreement commencing on the date that distribution agreement was executed,
August 5, 2005. The Company recorded the fair value of the warrants using the
Black-Scholes model

The Company converted the $500,000 loan to Luminetx into 250,000 shares of
Luminetx preferred stock, convertible into common stock on a share-for-share
basis, and warrants to purchase 50,000 shares of Luminetx common stock at $2.00
per share, exercisable for five years, as part of an $11 million private
placement financing that Luminetx announced on November 4, 2005. The Company
will invest the remaining $500,000 of the loan commitment to Luminetx for
preferred stock and warrants on the same terms. When Luminetx delivers to the
Company a minimum number of Vein Viewer (TM) Systems, as specified in the
distribution agreement.

(7) SEPTEMBER 30, 2005 PRIVATE PLACEMENT FINANCING AND WARRANT LIABILITY

On September 30, 2005 the Company completed a private placement which resulted
in gross proceeds of $10 million. In connection with this private placement, the
Company sold 4,000,000 shares of preferred stock at a price of $2.50 per share
and issued warrants to purchase up to 1,600,000 shares of common stock. The
warrants have a term of 5 years and an exercise price equal to $2.50. The
Investors may exchange shares of Preferred Stock for shares of Common Stock.
Each share of Preferred Stock may be exchanged for that number of shares of
Common Stock that equals the issue price of the Preferred Stock ($2.50) divided
by an exchange rate, initially set at $2.50 and subject to reduction in the case
of dilutive issuances.

Under the terms of the private placement, the Company has agreed to file a Form
SB-2 registration statement with the Commission covering the shares of Common
Stock that are issuable upon exchange under the Share Exchange Agreement and the
Common Stock that is issuable upon exercise of the Warrants. The Company agreed
to file the registration statement within 45 days of the date of the
Registration Rights Agreement, which the Company has complied with, having filed
a registration statement on November 9, 2005. The Company agreed to use its best
efforts to cause the registration statement to be declared effective within 120
days of the closing date of the purchase and sale of the Preferred Stock and the
Warrants. If the Company fails to comply, the Company will have to pay
liquidated damages of 3% per month of the aggregated purchase price paid by
investors for the Preferred Stock.

In accordance with Emerging Issues Task Force (EITF) number 00-27, "Application
of Issue No. 98-5 to Certain Convertible Instruments", (EITF 00-27) the Company
allocated the proceeds received in the financing between the preferred stock and
the warrants based on their relative fair values. Then the Company compared the
proceeds allocated to the preferred stock to the fair value of the common stock
that would be received upon conversion to determine if a beneficial conversion
feature existed. The Company determined that a beneficial


                                      F-44


                              DIOMED HOLDINGS, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2005
                                   (UNAUDITED)


conversion feature of $381,328 existed and, in accordance with EITF 00-27,
amortized that amount immediately to the value of the preferred stock, as the
preferred stock is immediately convertible. Further, as the fair value was less
than the conversion value, the Company recorded $381,328 as an increase to the
carrying value with an offset to additional paid-in capital. In accordance with
EITF 98-5 this combined adjustment of $762,656 is analogous to a dividend and
recognized as a return to the shareholders and has been included in Preferred
Stock Dividends in the Company's calculation of Net Loss Applicable to Common
Stockholders and Basic and Diluted Net Loss Per Share.

The Company further reduced the carrying value of the preferred stock by
$765,000 for specific incremental costs directly attributable to the transaction
including; investment banking, legal and professional fees.

EITF 00-19 "Accounting for Derivative Financial Instruments Indexed to, and
Potentially Settled in, a Company's Own Stock" (EITF 00-19) requires
freestanding contracts that are settled in a Company's own stock, including
common stock warrants, to be designated as an equity instrument, assets or
liability. Under the provisions of EITF 00-19, a contract designated as an asset
or liability must be carried at fair value until the contract meets the
requirements for classification as equity, until the contract is exercised or
until the contract expires.

According to the terms of the transaction, the Company is subject to certain
liquidated damages under the Registration Rights agreement if the Company cannot
obtain and maintain effectiveness of a registration statement. Since the
liquidated damages had no contractual maximum, the Company determined that the
liquidated damages were onerous and thus, could result in net-cash settlement of
the transaction in accordance with EITF 00-19. The Company valued the warrants
using the Black-Scholes model. The Company recorded a warrant liability of
$1,861,328 based on the relative fair value in accordance with EITF 00-27.
Because the warrants are classified as a liability, any changes in fair value
will be recorded as non-cash interest expense in the Statements of Operations
until the warrants are exercised, terminated or expired.

As the preferred stock includes stated dividend rates that increase over time,
from a rate considered below market, the Company will amortize an incremental
amount which together with the stated rate for the period results in a constant
dividend rate in accordance with Securities Exchange Commission Staff Accounting
Bulletin Topic 5Q. The Company determined that the present value of the
incremental dividends of $1,371,429 will be amortized over the period preceding
the perpetual dividend rate using an effective interest rate of 16.5%. The
Company will increase the carrying value of the preferred stock with an offset
to Additional Paid-in Capital periodically and reduce the carrying value when
paid. These dividends will be included in Preferred Stock Dividends in the
Company's calculation of Net Loss Applicable to Common Stockholders and Basic
and Diluted Net Loss Per Share.

In addition to the warrants we issued to the investors, we also issued warrants
to purchase up to 200,000 shares of common stock to the three holders of our
convertible debentures we issued in October 2004, as an inducement to, and in
consideration for, the debenture holders' waiver of certain negative covenants
that would have been violated by the financing had the debenture holders not
waived. These warrants were valued using the Black-Scholes model. As a result,
the Company recorded an additional debt discount to the September 28, 2004
convertible debentures of $256,969 which will be amortized to non cash interest
expense over the remaining term of the Notes.

The holders of the warrants may exercise their warrants by paying the Company
cash equal to the exercise price of the warrants, $2.50, or by means of a
"cashless exercise" instead of paying cash to the Company upon exercise, in
which case the holder shall be entitled to receive a certificate for the number
of warrant shares equal to the quotient obtained by dividing [(A-B) (X)] by (A),
where;

      (A) = the VWAP (as defined in the Warrant Agreement) on the date of
            exercise;

      (B) = the then current Exercise Price of the warrant, and

      (X) = the number of warrant shares issuable upon exercise of the warrant
            by means of a cash exercise rather than a cashless exercise

Because of this cashless exercise feature, the Company may not receive any
proceeds from the exercise of warrants (although the Company will issue a net
number of shares that is less than the total of 1,800,000 face amount of the
warrants).

(8) SEGMENT REPORTING

Operating segments are identified as components of an enterprise about which
separate discrete financial information is available for evaluation by the chief
operating decision maker, or decision making group, in making decisions on how
to allocate resources and assess performance. The Company's chief decision
making group, as defined under SFAS No. 131, is the Executive Management
Committee.

The Company's reportable segments are determined by product type: laser systems
and fibers, accessories and service. The Executive Management Committee
evaluates segment performance based on revenue. Accordingly, all expenses are
considered corporate level activities and are not allocated to segments. Also,
the Executive Management Committee does not assign assets to its segments.

This table presents revenues by reportable segment:

(9) COMMITMENTS AND CONTINGENCIES

On July 21, 2005, a lawsuit was filed against the Company in the United States
District Court for the Northern District of California by VNUS Medical
Technologies, Inc., alleging infringement of U.S. patents Nos. 6,258,084,
6,638,273, 6,752,803, and 6,769,433. The complaint was served on the Company on
July 27, 2005. On September 15, 2005, the Company filed an answer denying the
allegations of infringement, and counterclaiming against VNUS for a declaration
that none of the patents are infringed and that they are all invalid. On October
12, 2005, VNUS served an amended complaint adding two additional parties,
AngioDynamics, Inc. and Vascular Solutions, Inc., as defendants. On October 31,
2005, the Company filed an answer to the First Amended Complaint, again denying
the allegations of infringement, and counterclaiming against VNUS for a
declaration that none of the patents are infringed, that they are all invalid,
and that two of VNUS's patents are unenforceable for inequitable conduct. An
initial scheduling conference for the case has been set for December 2, 2005.
The Company intends to continue defending this case.

During 2004, the Company filed lawsuits in the United States Federal District
Court for the District of Massachusetts against four competitors seeking
injunctive relief and damages for infringement of the Company's U.S. Patent
Number 6,398,777 covering the endovascular laser treatment of varicose veins
which the Company uses in its EVLT(R) product line. If the Company's EVLT(R)
patent is judicially determined to be invalid, the Company will not prevail in
the infringement actions and will not be able to exclude third parties from
using the Company's EVLT(R) technology. As a result, the EVLT(R) patent may be
determined to be impaired and the Company's EVLT(R) revenue stream may be
adversely affected.

Insofar as legal proceedings other than patent litigation are concerned, from
time to time the Company is the defendant in legal and administrative
proceedings and claims of various types. Although any such litigation contains
an element of uncertainty, management, in consultation with the Company's
general counsel, presently believes that the outcome of such proceedings or
claims which are pending or known to be threatened, or all of them combined,
will not have a material adverse effect on the Company.

(10) SUBSEQUENT EVENTS

The Company converted the $500,000 loan to Luminetx into 250,000 shares of
Luminetx preferred stock, convertible into common stock on a share-for-share
basis, and warrants to purchase 50,000 shares of Luminetx common stock at $2.00
per share, exercisable for five years, as part of an $11 million private
placement financing that Luminetx announced on November 4, 2005. The Company
will invest the remaining $500,000 of the loan commitment to Luminetx for
preferred stock and warrants on the same terms, when Luminetx delivers to the
Company a minimum number of VeinViewer(TM) systems, as specified in the
distribution agreement.

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS


Section 145 of the Delaware General Corporation Law (the "DGCL") allows for the
indemnification of officers, directors, and other corporate agents in terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act. The Ninth Article of the Registrant's certificate of
incorporation and Article VII of the Registrant's bylaws authorize
indemnification of the registrant's directors, officers, employees and other
agents to the extent and under the circumstances permitted by the DGCL. The
Registrant maintains liability insurance for the benefit of its directors and
certain of its officers.

The above discussion of the DGCL and of the Registrant's certificate of
incorporation, bylaws and indemnification agreements is not intended to be
exhaustive and is qualified in its entirety by such statutes, amended and
restated certificate of incorporation, bylaws and indemnification agreements.


Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the SEC such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of our counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

the warrants issued in the transactio s with Verus International Group Limited
and Winton Capital Holdings Ltd. Prior to making any offer or sale, Diomed had
re sonable grounds to believe and believed that each of Verus International
Group Limited and Winton Capital Holdings Ltd. was capa le of evaluating the

of $339,336. Diomed determined this number of shares in accordance with the
provisions of the note regarding the conversion price of the note.


Diomed issued and sold these securities to QLT in reliance upon exemptions from
registration under the Securiaies Act set forth in Section 4(2) thereof or

Securities Act or exemption therefrom. QLT also represented it ietended to

Diomed issued and sold the securities in the above transaction in reliance upon
exemptions from registration under the Securities act of 1933, as amended, set
forth in Section 4(2) thereof or Regulation D or Regulation S thereunder. Each
purchaser represented that such purchaser was an accredited investor or not a
U.S. person, and each agreed that the securities would not be resold without
registration under the Securities Act or exemption therefrom. Each purchaser
also represented such purchaser's intention to acquire the securities for
investment only, and not with a view to the distribution thereof. Diomed affixed
appropriate legends to the stock certificates issued in such transactions. Prior
to making any offer or sale, Diomed had reasonable grounds to believe and
believed that each purchaser was capable of evaluating the merits and risks of
the investment and was able to bear the economic risk of the investment. The
shares of common stock issued by Diomed in the private placement on February 14,
2002 became shares of common stock of the Company when the Merger became
effective.

4) In April 2002, we entered into an agreement, referred to as the IRG
Agreement, with The Investor Relations Group, Inc., referred to as IRG, for
investor relations and public relations services. In connection therewith, we
granted to IRG 150,000 (6,000 after giving effect to the 1:25 reverse split
effected June 17, 2004) options, referred to as the Awarded Options, to purchase
shares of Class A Stock, (which, in connection with the Migratory Merger,
discussed below, became options to purchase the Company's Class A Stock), priced
at $5.35 per share ($133.75 per share after giving effect to the 1:25 reverse
split effected June 17, 2004). The Awarded Options were not granted under the
2001 Plan, but are subject to the terms and conditions of the 2001 Plan as if
granted thereunder. Any unvested Awarded Options were to terminate upon the
termination of the IRG Agreement. In November 2002, the Company terminated its
agreement with IRG. In accordance with the agreement, IRG owned 1,750 (after
giving effect to the 1:25 reverse split effected June 17, 2004) Awarded Options,
exercisable until November 2004. The Awarded Options so held expired without
exercise.


The Company issued and sold the options to IRG in the above transaction in
reliance upon exemptions from registration under the Securities act of 1933, as
amended, set forth in Section 4(2) thereof or Regulation D thereunder. IRG
represented that it was an accredited investor, and agreed that the securities
would not be resold without registration under the Securities Act or exemption
therefrom. IRG also represented its intention to acquire the securities for
investment only, and not with a view to the distribution thereof. The Company
affixed appropriate legends to the options issued in this transaction. Prior to
making any offer or sale, the Company had reasonable grounds to believe and
believed that IRG was capable of evaluating the merits and risks of the
investment and was able to bear the economic risk of the investment.


5) As a result of the Migratory Merger that occurred in May, 2002, the
outstanding capital securities of the Company prior to the Migratory Merger were
exchanged for comparable securities of the Company after the Migratory Merger.
There was no change in the number of outstanding common share equivalents of the
Company, which remained at 28,965,690 (1,158,627 after giving effect to the 1:25
reverse split effected June 17, 2004). However, each share of pre-Migratory
Merger Class A Stock, each share of which would have been convertible into four
shares of common stock on the basis of a pre-established schedule, received four
shares of post-Merger Class A Stock, each share of which is convertible into one
share of common stock on the basis of the same pre-established schedule. The
Migratory Merger did not result in any change in the restrictions on transfer
attaching to the 5,000,000 (200,000 after giving effect to the 1:25 reverse
split effected June 17, 2004) shares of the common stock sold in the February
14, 2002 private placement.


                                      II-3


The Company issued the securities in the Migratory Merger in reliance upon
exemptions from registration under the Securities act of 1933, as amended, set
forth in Section 3(a)(9) thereof. In the Migratory Merger, the securities of the
predecessor (Nevada) corporation were exchanged for like securities of the
successor (Delaware) and no commission or other remuneration was paid or given
for soliciting the exchange.


6) In August 2002, we re-valued the conversion price of the promissory note held
by QLT, Inc. (issued in connection with our purchase in October 2000 of QLT's
rights related to OPTIGUIDE(R) fibers) which QLT converted into common stock in
January 2002 to $1.50 per share ($37.50 per share after giving effect to the
1:25 reverse split effected June 17, 2004) and in so doing, we issued an
additional 90,489 (3,620 after giving effect to the 1:25 reverse split effected
June 17, 2004) shares of Class A Stock to QLT. QLT also converted a second
promissory note held by QLT (also issued in connection with our purchase in
October 2000 of QLT's rights related to OPTIGUIDE(R) fibers) at a conversion
price of $1.50 per share ($37.50 per share after giving effect to the 1:25
reverse split effected June 17, 2004), and we issued 605,570 (2,423 after giving
effect to the 1:25 reverse split effected June 17, 2004) shares of Class A Stock
to QLT in that connection.


The Company issued and sold these securities to QLT in reliance upon exemptions
from registration under the Securities Act set forth in Section 4(2) thereof or
Regulation S thereunder. QLT represented that it was not a U.S. person and
agreed that the securities would not be resold without registration under the
Securities Act or exemption therefrom. QLT also represented it intended to
acquire the securities for investment purposes only and not with a view to the
distribution thereof. The common stock was not issued in certificated form.
Before making any offering of the securities to QLT, Diomed had reasonable
grounds to believe and believed that QLT was capable of evaluating the merits
and risks of the investment and was able to bear the economic risk of the
investment.


7) In November 2002, we issued an aggregate of 50,000 (2,000 after giving effect
to the 1:25 reverse split effected June 17, 2004) shares of common stock to the
purchasers of common stock in our February 14, 2002 private placement. We issued
these shares because the registration statement we filed registering the private
placement common stock did not become effective within 240 days of the private
placement. (The registration statement was declared effective by the SEC as of
October 25, 2002). According to the private placement agreement, we were
required to issue 1% of the shares purchased in the private placement for each
month after the 240 day deadline during which the registration statement was not
effective.


The Company filed a registration statement on Form SB-2MEF simultaneously with
the issuance of these shares of common stock. This registration statement became
effective immediately upon filing with the SEC.


8) In December 2002, in consideration for aggregate gross proceeds to Diomed of
$2,000,000 paid by Gibralt U.S., Inc. and pursuant to the terms and conditions
of a Note Agreement, the Company issued to Gibralt U.S. (i) warrants to purchase
up to 8,333,333 (333,333 after giving effect to the 1:25 reverse split effected
June 17, 2004) shares of common stock at an exercise price of $.26 per share
($6.50 per share after giving effect to the 1:25 reverse split effected June 17,
2004), which warrants become exercisable on May 27, 2003 and expire on May 27,
2008, and (ii) $1,000,000 principal amount Class A Secured Convertible Notes due
January 1, 2004 and $1,000,000 principal amount of Class B Unsecured Convertible
Notes due January 1, 2004, which Notes bear interest at the rate of 8% per
annum, and are convertible into common stock at the option of the holder(s) upon
at least 60 days written notice to the Company or, at the option of the
holder(s) upon the occurrence of certain transactions or events, specified in
the Note Agreement. The rate of conversion is 80% of the Common Stock Price (as
defined in the Note Agreement), which cannot be ascertained until a conversion
is requested because it is based on the market price of the common stock during
the period prior to the date that conversion is requested. The Company granted
certain registration rights in connection with the common stock which may be
issued upon exercise of the warrants and/or conversion of the Notes pursuant to
a registration rights agreement. In addition, the Company granted a lien in
certain assets of Diomed to the holder(s) of the Class A Secured Convertible
Notes, and pledged to the Class A Secured Convertible Note holders 100% of the
shares of Diomed PDT, Inc., a wholly-owned Delaware subsidiary of Diomed which
owns certain assets related to the Company's PDT business. Under the terms of
the Note Agreement, Gibralt U.S. is the "Designated Purchaser" with authority to
perform certain actions relating to the Notes on behalf of the other holders of
Notes, although this authority does not include investment discretion over the
Notes or the Warrants.


Gibralt U.S. is an affiliate of Samuel Belzberg, a former director of Diomed
Holdings and Diomed until February 2004. The Company believes the terms of this
bridge financing were no less favorable to Diomed Holdings and/or Diomed than if
the transaction were with a non-affiliate of the Company. This bridge financing
transaction was approved by the Audit Committee of the board of directors of
Diomed Holdings and by the boards of directors of Diomed Holdings and Diomed.

On March 18, 2003, Gibralt U.S. sold and transferred to three investors in a
private transaction (i) $500,000 aggregate principal amount of Notes ($250,000
of which are Class A Notes and $250,000 of which are Class B Notes), and (ii)
2,083,334 (83,333 after giving effect to the 1:25 reverse split effected June
17, 2004) warrants. Accordingly, after the taking effect of this transfer, Mr.
Belzberg beneficially owned 6,249,999 (250,000 after giving effect to the 1:25
reverse split effected June 17, 2004) warrants and $1,500,000 aggregate
principal amount of Notes.

                                      II-4


The Company issued and sold the securities in the above transaction in reliance
upon exemptions from registration under the Securities act of 1933, as amended,
set forth in Section 4(2) thereof or Regulation D thereunder. Gibralt U.S.
represented that it was an accredited investor, and agreed that the securities
would not be resold without registration under the Securities Act or exemption
therefrom. Gibralt U.S. also represented its intention to acquire the securities
for investment only, and not with a view to the distribution thereof. The
Company affixed appropriate legends to the Notes and warrant certificate issued
in this transaction. Prior to making any offer or sale, the Company had
reasonable grounds to believe and believed that Gibralt U.S. was capable of
evaluating the merits and risks of the investment and was able to bear the
economic risk of the investment.


9) On May 7, 2003, the Company issued to the December 2002 noteholders a total
of 20 shares of Class C Convertible Preferred Stock, convertible into a total of
27,117,240 (1,084,690 after giving effect to the 1:25 reverse split effected
June 17, 2004) shares of common stock, in exchange for the convertibility
feature of the $2,000,000 principal amount of notes and their warrants to
purchase 8,333,333 (333,333 after giving effect to the 1:25 reverse split
effected June 17, 2004) shares of common stock, as well as certain other rights.
The terms of the Notes issued in the December 2002 financing were amended
accordingly, and the Company issued Class (C Secured Notes in exchange for the
Class A and B Notes issued in December 2002.

On May 28, 2003, the Company and the December 2002 noteholders agreed to certain
further revisions of the terms of the Notes issued in December 2002, including
extending the maturity date to January 1, 2006, limiting the collateral securing
the Notes and increasing to 12.5% the interest rate on the Notes. The December
2002 noteholders exchanged their Class C Notes for an equal principal amount of
Class E Notes, reflecting the revised terms. All of the Class E Notes were
redeemed by the Company on September 3, 2003, using a portion of the proceeds
from the first closing of the Company's equity financing which occurred on that
date, and no Class E Notes remain outstanding.


The Company issued and sold the securities in the above transactions in reliance
upon exemptions from registration under the Securities act of 1933, as amended,
set forth in Section 4(2) thereof or Regulation D thereunder. Each of the
December 2002 noteholders represented that it was an accredited investor, and
agreed that the securities would not be resold without registration under the
Securities Act or exemption therefrom. Each of the December 2002 noteholders
also represented its intention to acquire the securities for investment only,
and not with a view to the distribution thereof. The Company affixed appropriate
legends to the Notes issued in these transactions. Prior to making any offer or
sale, the Company had reasonable grounds to believe and believed that the
December 2002 noteholders were capable of evaluating the merits and risks of the
investment and was able to bear the economic risk of the investment.


10) On May 7, 2003, the Company issued Class D Secured Notes in the aggregate
principal amount of $1,200,000 in connection with loans committed by three
affiliates of the Company, Gibralt U.S., an affiliate of Samuel Belzberg, a
former director of the Company ($1,100,000), Peter Norris, a director of the
Company ($50,000) and James A. Wylie, Jr., a director and the chief executive
officer of the Company ($50,000). The terms of these Notes provide that they are
redeemable for securities that the Company issues in an equity financing
transaction entered into after the issuance of these Notes, on the same terms
and conditions as the other investors in such an equity financing.


In connection with this financing, the Company also issued to the lenders a
total of 24 shares of Class D Convertible Preferred Stock, convertible into a
total of 3,021,552 (120,862 after giving effect to the 1:25 reverse split
effected June 17, 2004) shares of common stock, allocated among the lenders in
proportion to their respective loan commitments, as compensation in
consideration of the increased that they were taking by funding the operations
of the Company in advance of investors in the future equity financing.

The Company issued and sold the securities in the above transactions in reliance
upon exemptions from registration under the Securities act of 1933, as amended,
set forth in Section 4(2) thereof or Regulation D thereunder. Each of the May
2003 noteholders represented that it was an accredited investor, and agreed that
the securities would not be resold without registration under the Securities Act
or exemption therefrom. Each of the May 2003 noteholders also represented its
intention to acquire the securities for investment only, and not with a view to
the distribution thereof. The Company affixed appropriate legends to the Notes
issued in these transactions. Prior to making any offer or sale, the Company had
reasonable grounds to believe and believed that the May 2003 noteholders were
capable of evaluating the merits and risks of the investment and was able to
bear the economic risk of the investment.


11) On August 22, 2003, pursuant to the stipulation of settlement that we
reached in a class action lawsuit filed against us in July 2003, we entered into
exchange agreements with the holders of the outstanding shares of our Class C
Convertible Preferred Stock (the "Class C Stock") and Class D Convertible
Preferred Stock (the "Class D Stock"). Upon entering into the exchange
agreements, the holders of the Class C Stock exchanged their Class C Stock for
20 shares of Class E Stock, on a share-for-share basis. Similarly, upon
execution of the exchange agreements, the holders of the 24 outstanding Class D
Stock exchanged their Class D Stock for shares of Class F Stock, on a
share-for-share basis. Following these exchanges, we eliminated all Class C
Stock and all Class D Stock.


                                      II-5


Shares of the Class E and Class F Stock are preferred in liquidation to the
extent that, before any distribution of assets can be made to the holders of the
common stock, there will be distributed pro rata to the holders of the issued
and outstanding shares of Class E Stock and Class F Stock the amount of $108,469
as to each outstanding share of Class E Stock and $10,072 per share as to each
outstanding share of Class F Stock. The holders of the common stock then share
in the remainder of net liquidation of proceeds. The aggregate liquidation
preference of the Class E Stock is $2,169,380 and the aggregate liquidation
preference of the Class F Stock is $241,728.

The holders of the Class E Stock are entitled to cash dividends and
distributions when and as declared by the board of directors, pari passu with
the holders of our common stock with the dividend amount on each share of Class
E Stock being 1,355,862 (54,234 after giving effect to the 1:25 reverse split
effected June 17, 2004) times the dividend or distribution to be paid on each
share of common stock. The holders of the Class F Stock are entitled to cash
dividends and distributions when and as declared by the board of directors, pari
passu with the holders of our common stock with the dividend amount on each
share of Class F Stock being 125,898 (5,036 after giving effect to the 1:25
reverse split effected June 17, 2004) times the dividend or distribution to be
paid on each share of common stock.

The exchange agreements also gave both the Company and the holders of the Class
E Stock and the Class F Stock rights to exchange those preferred shares for
shares of our common stock, as long as our stockholders approve the issuance of
the shares of our common stock underlying the preferred shares and the AMEX
approves the listing of these shares of common stock. Specifically, if the
stockholders approve the common stock issuance and the AMEX lists these the
shares of common stock, then the holders of the Class E Stock have the right to
sell to us, and we have the right to purchase from them, each outstanding share
of Class E Stock in exchange for 1,355,862 (54,234 after giving effect to the
1:25 reverse split effected June 17, 2004) shares of our common stock per share
of Class E Stock. Similarly, the holders of the Class F Stock have the right to
sell to us, and we have the right to purchase from them, each outstanding share
of Class F Stock in exchange for 125,898 (5,036 after giving effect to the 1:25
reverse split effected June 17, 2004) shares of our common stock per share of
Class F Stock. The exchange agreements also provided that, should any sale,
lease, exchange or other disposition of all or substantially all of our assets
occur while shares of Class E Stock and Class F Stock are outstanding, each
holder of the Class E Stock has the right to sell to us all shares of Class E
Stock held in exchange for 1,355,862 (54,234 after giving effect to the 1:25
reverse split effected June 17, 2004) shares of common stock per share of Class
E Stock. Similarly, each holder of the Class F Stock has the right to sell to us
all shares of Class F Stock held in exchange for 125,898 (5,036 after giving
effect to the 1:25 reverse split effected June 17, 2004) shares of common stock
per share of Class F Stock.

The board of directors determined that the terms of the exchange agreements were
appropriate in order to provide the former holders of the Class C Stock and the
Class D Stock with the economic equivalence of the conversion rights they held
in conjunction with the Class C Stock and Class D Stock. Upon exchange of all
Class E Stock, the former holders of the Class C Stock will receive 27,117,240
(1,084,690 after giving effect to the 1:25 reverse split effected June 17, 2004)
shares of our common stock, or the same number of shares of our common stock we
were obligated to issue to them upon conversion of the Class C Stock. Upon
exchange of all shares of the Class F Stock, the former holders of the Class D
Stock will receive 3,021,552 (120,862 after giving effect to the 1:25 reverse
split effected June 17, 2004) shares of common stock, or the same number of
shares of our common stock that we were obligated to issue to them upon
conversion of the Class D Stock.

The Company issued its preferred shares to the above-referenced persons in
reliance upon the exemption from registration set forth under Section 4(2) of
the Securities Act of 1933, as amended. Each such person agreed that neither the
options or notes, as the case may be, nor the underlying securities would be
resold without registration under the Securities Act or exemption therefrom.
Each such person also represented his or its intention to acquire the securities
for investment only, and not with a view to the distribution thereof. Prior to
making any offer or sale, we had reasonable grounds to believe and believed that
the security holder was capable of evaluating the merits and risks of the
investment and was able to bear the economic risk of the investment represented
by the options granted.


12) On September 3, 2003, at the first closing of our equity financing
transaction, we issued an aggregate principal amount of $6,995,000 in Secured
Bridge Notes due 2004 to 119 accredited investors. The principal and accrued
interest on these Secured Bridge Notes will convert into shares of common stock
at the conversion price of $0.08 per share ($2.00 per share after giving effect
to the 1:25 reverse split effected June 17, 2004) when we complete the equity
financing. The names of the investors in the equity financing to whom we issued
Secured Bridge Notes, the principal amount of the Secured Bridge Notes issued to
each such investor and the number of shares of common stock into which the
Secured Bridge Notes will convert are set forth below. These investors include
Gibralt U.S., Inc., an affiliate of one of the Company's former directors,
Samuel Belzberg. The numbers of shares set forth below do not give effect to the
1:25 reverse split effective June 17, 2004.

We received gross proceeds of $6,500,000 from the issuance of the Secured Bridge
Notes. We applied a portion of these proceeds to repay in full all of our
outstanding Class E notes (approximately $2,140,000 of principal and interest,
including approximately $1,575,000 repaid to Gibralt U.S., Inc., an affiliate of
Samuel Belzberg, a former director of the Company) and to acquire additional
intellectual property rights related to our EVLT(R) product line ($2,000,000).
We also paid fees incurred by legal counsel to the investors (approximately
$100,000) and reimbursable expenses incurred by our placement agent
(approximately $14,000). Our intention was to use the balance of these proceeds
for general working capital purposes.

As part of the compensation payable to our placement agent, Sunrise Securities
Corp., in connection with our equity financing, on September 3, 2003, we issued
warrants to purchase up to a total of 40,879,063 (1,635,163 after giving effect
to the 1:25 reverse split effected June 17, 2004) shares of common stock to our
placement agent. The warrants may be exercised for a five-year period beginning
when our stockholders approved the issuance of shares of our common stock
underlying these warrants and those shares have been listed for trading on the
AMEX. The following table sets forth the respective exercise prices of these
warrants. The numbers of shares set forth below do not give effect to the 1:25
reverse split effected June 17, 2004.

The Company issued its securities to the above-referenced persons in reliance
upon the exemption from registration set forth under Section 4(2) of the
Securities Act of 1933, as amended. Each such person agreed that neither the
notes, common stock or warrants, as the case may be, nor the underlying
securities, would be resold without registration under the Securities Act or
exemption therefrom. Each such person also represented his, her or its intention
to acquire the securities for investment only, and not with a view to the
distribution thereof. Prior to making any offer or sale, we had reasonable
grounds to believe and believed that the purchaser was capable of evaluating the
merits and risks of the investment and was able to bear the economic risk of the
investment represented by the options granted.

                                      II-8



13) On September 3, 2003, in connection with our purchase from Robert J. Min,
M.D. of his interest in the technology we use in our EVLT(R) products and
services, we issued options to purchase 1,000,000 (40,000 after giving effect to
the 1:25 reverse split effected June 17, 2004) shares of common stock to Dr.
Min.

The Company issued these options to Dr. Min in reliance upon the exemption from
registration set forth under Section 4(2) of the Securities Act of 1933, as
amended. Dr. Min agreed that neither the options or notes, as the case may be,
nor the underlying securities would be resold without registration under the
Securities Act or exemption therefrom. Dr. Min also represented intention to
acquire the securities for investment only, and not with a view to the
distribution thereof. Prior to making any offer or sale, we had reasonable
grounds to believe and believed that the purchaser was capable of evaluating the
merits and risks of the investment and was able to bear the economic risk of the
investment represented by the options granted.

14) On September 30, 2003, we agreed to issue 500,000 (20,000 after giving
effect to the 1:25 reverse split effected June 17, 2004) shares of common stock
to Verus Support Services, Inc. to satisfy our obligations arising under a
December 2001 agreement between us and Verus. We believe that Verus is no longer
a holder of greater than 5% of common stock. We engaged Verus as our financial
advisor for the period ended August 31, 2003. Under that agreement, we were to
pay Verus $15,000 per month for these services. We ceased making the $15,000
monthly payments to Verus beginning August 2002. On September 30, 2003, we
entered into an agreement with Verus pursuant to which we were to issue to Verus
a total of 500,000 (20,000 after giving effect to the 1:25 reverse split
effected June 17, 2004) shares of common stock in lieu of the monthly payments
that we did not pay to Verus. The issuance of these shares was contingent on the
completion of the equity financing, and we were to issue these shares to Verus
within three days after we completed the equity financing. We issued these
shares on November 25, 2003, the same day that we completed the equity
financing.

The Company issued securities to the Verus in reliance upon the exemption from
registration set forth under Section 4(2) of the Securities Act of 1933, as
amended. Each such person agreed that neither the common stock would not be
resold without registration under the Securities Act or exemption therefrom.
Verus also represented its intention to acquire the securities for investment
only, and not with a view to the distribution thereof. Prior to making any offer
or sale, we had reasonable grounds to believe and believed that Verus was
capable of evaluating the merits and risks of the investment and was able to
bear the economic risk of the investment represented by the shares to be issued.

15) On September 28, 2004, we entered into definitive agreements for the sale
and issuance of convertible debentures, common stock and warrants to purchase
common stock to certain accredited investors in a private placement financing
transaction. On October 25, 2004, after the AMEX approved our application list
the shares to be issued in this financing, we completed this transaction. We
received net proceeds of approximately $9.8 million from this transaction, which
will be used for general working capital purposes.

The following summarizes the principal terms of the transaction:


Variable Rate Convertible Debentures

We issued an aggregate of $7,000,000 principal amount of convertible debentures
at par. The convertible debentures bear interest (payable quarterly in arrears
on March 31, June 30, September 30 and December 31) at a variable rate of 400
basis points over six-month LIBOR and mature four years from the date of
issuance.

The debentures are convertible at any time at the option of the holder into
common stock at a conversion price of $2.29 per share, which was 120% of the
$1.91 per share closing price of the common stock on the AMEX on the trading day
prior to the date that we and the investors signed the definitive purchase
agreements The conversion price is subject to certain adjustments, with a
minimum conversion price of $2.20 per share unless we obtain stockholder
approval to reduce the conversion price below $2.20.

Subject to certain conditions, the debentures will also be convertible at our
option at any time after the first anniversary of the issuance date if the
closing price of the common stock equals or exceeds 175% of the conversion price
for at least 20 consecutive trading days. Also subject to certain conditions,
upon maturity, we may cause the holders to convert the entire principal amount
of debentures outstanding into shares of common stock upon maturity, at a price
per share equal to the lesser of the stated conversion price and 90% of the
volume weighted average trading price of its common stock for the 20 days prior
to the maturity date.

After the first year and at our option, subject to certain conditions, interest
may be paid in shares of its common stock in lieu of cash, at a conversion price
which is based on the closing prices of the common stock on the fifth through
first trading days immediately preceding the interest payment date. The
conversion rate for interest will be discounted by 10% if we obtain stockholder
approval of this discount. In any event, though, without stockholder approval,
the conversion rate for interest will not be less than $1.91, the closing price
of the common stock on the AMEX on the trading day prior to the date that the
Company and the investors signed the definitive purchase agreements.

Common Stock

We issued and sold, for an aggregate gross purchase price of $3,614,503, shares
of its common stock at a purchase price of $1.53 per share, which is 80% of the
closing price of the common stock on the AMEX on the trading day prior to the
date that we and the investors signed the definitive purchase agreements.
Accordingly, we issued a total of 2,362,420 shares of common stock to the
investors who purchased common stock in this transaction.

Warrants to Purchase Common Stock


In connection with the issuance of both the convertible debentures and the
common stock, we issued warrants to purchase shares of common stock. We issued
warrants to purchase up to 1,832,461 shares of common stock to the investors who
purchased convertible debentures and we issued warrants to purchase up to
1,181,210 additional shares of common stock to the investors who purchased
common stock. The warrants are exercisable for five years from the date of
issuance at an exercise price of $2.10 per share, which is 110% of the $1.91 per
share closing price of the common stock on the AMEX on the trading day prior to
the date that we and the investors signed the definitive purchase agreements.
The exercise price is subject to certain adjustments, including for future sales
of securities below the exercise price, with a minimum exercise price of $1.91
per share unless we obtain stockholder approval to reduce the exercise price
below $1.91. In addition, if the shares of common stock underlying the warrants
are not registered with the United States Securities and Exchange Commission
(the "Commission") within one year from the closing date, the warrant holders
may exercise their warrants by means of a "cashless exercise" at a formula set
forth in the form of warrant instead of paying cash to us upon exercise.


                                     II-10


Registration of Common Stock


We have agreed to undertake registration with the Commission of the common stock
and common stock underlying the convertible debentures and warrants.
Accordingly, we were required to file a registration statement with the
Commission within 30 days of the closing date of the financing transaction,
which registration must have been declared effective by the Commission within 90
days of the closing date (or 120 days if the Commission reviews the registration
statement). If we did not file the registration statement within 30 days of the
closing date or if the Commission did not declare the registration statement
effective within the prescribed time period, we would have been required to pay
certain amounts to the investors. This registration statement is the
registration statement we agreed to file in connection with the 2004 equity
financing.

16) In connection with the private placement debt and equity financing we
completed on October 25, 2004, we made adjustments to warrants that we had
issued in 2003 to designees of Sunrise Securities Corp., our placement agent in
our 2003 equity financing. The warrants we issued to these persons in 2003 were
subject to an anti-dilution adjustment for future equity financing transactions.
This adjustment was triggered on October 25, 2004, and as a result, the
outstanding warrants with exercise prices of $2.00 were adjusted to $1.93 and
7,588 additional warrants were issued, and the warrants with exercise prices of
$2.50 were adjusted to $2.32 and 48,145 additional warrants were issued. In
addition, pursuant to our agreement with Sunrise, on October 25, 2004 we also
issued to designees of Sunrise warrants to purchase 73,539 shares of common
stock, at an exercise price of $2.01 per share, as additional fees payable due
to participation in the 2004 private placement by investors introduced by
Sunrise in our 2003 equity financing. These warrants have substantially the same
terms and conditions as those warrants that we issued to the investors in our
2004 debt and equity financing.

We issued the warrants to the above-referenced persons in reliance upon the
exemption from registration set forth under Section 4(2) of the Securities Act
of 1933, as amended. Each such person agreed that neither the warrants nor the
underlying securities would be resold without registration under the Securities
Act or exemption therefrom. Each such person also represented his or its
intention to acquire the securities for investment only, and not with a view to
the distribution thereof. Prior to making any offer or sale, we had reasonable
grounds to believe and believed that the security holder was capable of
evaluating the merits and risks of the investment and was able to bear the
economic risk of the investment represented by the warrants granted.

17) In connection with our distribution agreement we entered into with Luminetx
Corporation pursuant to which we shall act as distributor of Luminetx's
VeinViewer(TM) system, on August 5, 2005, we issued to Luminetx warrants to
purchase up to 600,000 shares of common stock. The warrants have an exercise
price of $2.90 per share, become exercisable when the underlying shares are
listed with the American Stock Exchange and cease to be exercisable on the
earlier of five years from full vesting, August 5, 2011 and the date of
termination of the distribution agreement. The warrants were immediately
exercisable (subject to prior listing of the underlying shares with the AMEX) as
to 50% of the underlying shares, with the remainder to become exercisable when
Luminetx has both (A) produced at least 100 units of the system and (B) Diomed
shall have accepted delivery of at least 25 units of the system.

We issued the warrants to Luminetx in reliance upon the exemption from
registration set forth under Section 4(2) of the Securities Act of 1933, as
amended. Luminetx agreed that neither the warrants nor the underlying common
stock would be resold without registration under the Securities Act or exemption
therefrom. Luminetx also represented its intention to acquire the securities for
investment only, and not with a view to the distribution thereof. Prior to
making any offer or sale, we had reasonable grounds to believe and believed that
Luminetx was capable of evaluating the merits and risks of the investment and
was able to bear the economic risk of the investment represented by the warrants
granted.

18) On September 30, 2005, we completed a financing transaction pursuant to
which we issued and sold 4,000,000 shares of preferred stock at a purchase price
of $2.50 per share. We also agreed that the holders of the preferred stock may
exchange the preferred stock for common stock (on a share-for-share basis,
subject to antidilution adjustments). We also issued to the investors warrants
to purchase an aggregate of 1,600,000 shares of common stock, at an exercise
price of $2.50 per share (subject to antidilution adjustments). In addition to
the warrants we issued to the investors, we also issued warrants to purchase up
to 200,000 shares of common stock to the three holders of our convertible
debentures we issued in October 2004, as an inducement to, and in consideration
for, the debenture holders' waiver of certain negative covenants that would have
precluded the preferred stock financing. The Company received aggregate gross
proceeds of $10 million from the sale of these shares.

We entered into a share exchange agreement with the investors who purchased
preferred stock, pursuant to which the investors may exchange shares of
preferred stock for shares of common stock. Each share of preferred stock may be
exchanged for that number of shares of common stock that equals the issue price
of the preferred stock ($2.50) divided by an exchange rate, initially set at
$2.50 and subject to reduction in the case of dilutive issuances.


                                     II-11


The antidilution adjustment provides that if we sell common stock (or the right
to acquire common stock) for a price lower than the then-current exchange rate,
the exchange rate will be reduced to the amount paid for the shares of common
stock, subject to a floor of $2.17, unless the stockholders of the Company
approve the elimination of the floor price. We agreed to propose to our
stockholders that the floor price be eliminated. If the stockholders approve
this proposal and we make a dilutive issuance, then the exchange rate for the
preferred stock may be decreased, first to the floor price, then to the weighted
average price of the securities issued after giving effect to the dilutive
issuance.

We agreed to pay liquidated damages to the investors if we fail to comply with
an investor's request to exchange preferred stock for common stock, if the
registration statement covering the common stock underlying the preferred stock
and the warrants is not declared effective by the Commission within 120 days of
the September 30, 2005 closing date (or, after being declared effective by the
Commission, is unavailable to the investors for the resale of their common
stock) or if the common stock is suspended from trading or is not listed on an
exchange. The liquidated damages will be equal to 3% per month of the aggregate
purchase price paid by investors for the preferred stock.

If certain redemption events set forth in the exchange agreement occur, the
investors have the right to redeem their shares of preferred stock for cash at a
20% redemption premium over the issue price. These events include those events
entitling the investors to receive liquidated damages if not remedied during
applicable cure periods, and in addition the failure to remove restrictive
legends upon an investor's request when permitted under applicable law, our
announcement that we intend not to issue common stock in exchange for preferred
stock, bankruptcy events, a default under indebtedness of the Company or one of
our material agreements or a concentration of ownership of the Company's capital
stock of 35% which continues for 30 days. After five years, we also have the
right to redeem the preferred stock at a 20% premium over the issue price.

The holders of outstanding shares of preferred stock are entitled to cumulative
annual dividends at the rate of: (i) 6%, for the first 18 months following the
initial sale of preferred stock, (ii) 10% from the 19th through the 24th month
following the initial sale and (iii) 15% after the 24th month following the
initial sale. The dividends shall accrue from day-to-day on each share of
preferred stock, whether or not earned or declared, and shall accrue until paid.
We may pay the dividends with either cash or shares of common stock. The
dividends will not accrue on any days where the volume weighted average price of
the common stock for the 30 prior trading days equals or exceeds $6.25, so long
as the shares of common stock for which the preferred stock may be exchanged
under the exchange agreement are subject to an effective registration statement,
the shares of common stock for which the preferred stock may be exchanged and
the common stock underlying warrants is authorized and reserved for issuance and
listed on a trading market, none of the events giving rise to an investor's
right to redeem the preferred stock under the exchange agreement shall have
occurred and not been cured and we do not owe the investors more than $15,000,
in the aggregate, under the transaction documents for the private placement
financing.

Each holder of preferred stock is entitled to one vote per share of issued and
outstanding preferred stock owned by such holder on the record date for the
determination of stockholders entitled to vote, and the holders of the preferred
stock and the common stock shall vote together as a single class (except where
the Delaware General Corporation Law provides that a separate vote of the
holders of preferred stock is required for approval of certain matters, in which
case a majority of the shares of preferred stock outstanding shall be required
for approval).

The preferred stock is preferred over the common stock, and any class or series
of capital stock that our board of directors may create in the future, as to the
assets of the Company available for distribution to the stockholders in the
event of the liquidation, dissolution or winding up of the Company, the sale of
all or substantially all of the assets of the Company or the merger or
consolidation of the Company with another entity that results in either the
stockholders of the Company having less than 50% of the outstanding voting
securities of the successor company in the merger or combination transaction or
the members of the board of directors of the Company constituting 50% or less
than the members of the board of directors of the successor company in the
merger. Upon the occurrence of one of the transactions listed above, the holders
of preferred stock are to receive, before any distribution or payment is made to
any holders of common stock, the greater of: (i) $3.00 per share of preferred
stock, plus all accrued and unpaid dividends thereon, and (ii) such amount per
share of preferred stock that would have been payable had each share of
preferred stock been tendered in exchange for common stock immediately prior to
the transaction.

                                     II-12


The warrants are exercisable for five years from the date of listing of the
underlying shares of common stock with the AMEX at an exercise price of $2.50
per share, subject to reduction in the case of dilutive issuances. The
antidilution adjustment provides that if we sell common stock (or the rights to
acquire common stock) for a price lower than the then-current exercise price,
the exercise price will be reduced to the amount paid for the shares of common
stock we issued at such lower price, subject to a floor of $2.12, unless the
stockholders of the Company approve the elimination of the floor price. We
agreed to propose to its stockholders that the floor price be eliminated. If the
stockholders approve this proposal and we make a dilutive issuance, then the
exercise price of the warrants may be decreased, first to the floor price, then
to the weighted average price of the securities issued after giving effect to
the dilutive issuance. If the exercise price of the warrants is so adjusted,
then there will concurrently be an adjustment to the number of shares for which
the warrant will be exercisable, by dividing the product of the former exercise
price multiplied by the number of shares underlying the warrant by the adjusted
exercise price.

In addition, the holders of the warrants may exercise their warrants by means of
a "cashless exercise" instead of paying cash to us upon exercise, in which case
the purchase price otherwise payable in cash by the holder will be paid by
crediting the holder for the excess of the market value of the common stock at
the time of exercise over the exercise price of the stock.

The following are the persons to whom we issued and preferred stock and warrants
in the September 30, 2005 financing:

We issued the preferred stock and warrants to the above-referenced persons in
reliance upon the exemption from registration set forth under Section 4(2) of
the Securities Act of 1933, as amended. Each such person agreed that neither the
warrants nor the underlying securities would be resold without registration
under the Securities Act or exemption therefrom. Each such person also
represented his or its intention to acquire the securities for investment only,
and not with a view to the distribution thereof. Prior to making any offer or
sale, we had reasonable grounds to believe and believed that the security holder
was capable of evaluating the merits and risks of the investment and was able to
bear the economic risk of the investment represented by the warrants granted.


- -----

All of the above transactions were made directly without use of an underwriter.
In each case the aggregate sales proceeds (if any), after payment of offering
expenses in immaterial amounts, were applied to our working capital and other
general corporate purposes.

ITEM 28. UNDERTAKINGS

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities
Act;


(ii) to reflect in the prospectus any facts or events arising after the
effective date of this registration statement (or the most recent post-effective
amendment hereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in this registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b), if in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.


(iii) to include any material information with respect to the plan of
distribution not previously disclosed in this registration statement or any
material change to such information in this registration statement.

(2) That, for the purpose of determining any liability under the Securities Act,
each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the SEC such indemnification
is against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of our counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.


(4) That, in connection with the registrant's anticipated request for
acceleration of the effective date of the registration statement under Rule 461
under the Securities Act:


Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim form indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the
final adjudication of such issue.
