(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 of varicose veins(EVLT(R)). 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.

(2) BASIS OF PRESENTATION

In the opinion of management, these unaudited consolidated financial statements
contain all adjustments considered normal and recurring and necessary for their
fair presentation. Interim results are not necessarily indicative of results to
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.

(a) RECLASSIFICATIONS

Certain reclassifications have been made in the prior year consolidated
financial statements to conform to the current year's presentation.

(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
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. 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.

(e) MARKETABLE SECURITIES

Debt securities, U.S. Agency Notes and Corporate Bonds, are classified as
"available-for-sale securities" and reported at fair value, with unrealized
gains and losses excluded from operations and reported as a component of
accumulated other comprehensive income (loss), net of the related tax effects,
in stockholders' equity.

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

Gross unrealized losses for the three months and six months ended June 30, 2005
totaled $2,099.


(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. As a result of the losses incurred by the Company for
the three and six-month periods ended June 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.

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 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.

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

(6) 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:

(7) COMMITMENTS AND CONTINGENCIES

From time to time the Company is the defendant 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.

On July 21, 2005, a lawsuit was filed against the Company in the United States
Federal District Court for the Northern District of California by VNUS Medical
Technologies, Inc. ("VNUS"), alleging infringement of U.S. patents Nos.
6,258,084, 6,638,273, 6,752,803, and 6,769,433. Diomed intends to vigorously
defend the lawsuit.

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.

(8) SUBSEQUENT EVENTS

On August 5, 2005, Diomed acquired exclusive distribution rights to the Luminetx
VeinViewer(TM) Imaging System for the sclerotherapy, phlebectomy and varicose
vein treatment markets in the United States and United Kingdom. The
VeinViewer(TM), cleared by the FDA in 2004, is a patented imaging system
developed by Luminetx, Inc. of Memphis, Tennessee which utilizes infrared light
to illuminate on a real-time basis subcutaneous veins and project their location
on the surface of the skin with an accuracy of 0.06 mm. VeinViewer(TM) is
designed to allow physicians to visualize the location and orientation of the
patient's veins, thereby providing more precise sclerotherapy and phlebectomy
procedures through increased accuracy in vein mapping and imaging.

The 3 year agreement includes both a $1 million phased investment in Luminetx
and a grant of warrants to purchase 600,000 shares of Diomed common stock both
based upon the achievement of certain milestones. Details of the transaction can
be found in the Company's Current Report on SEC Form 8K filed with the SEC on
August 11, 2005.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF OPERATIONS

In this Quarterly Report, the terms "Company" and "Diomed Holdings" both refer
to Diomed Holdings, Inc. The term "Diomed" refers to the Company's principal
subsidiary, Diomed, Inc. and its consolidated subsidiaries. We use the terms
"we,", "our" and "us" when we do not need to distinguish among these entities or
their predecessors, or when any distinction is clear from the context.

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. Our 2004 Annual
Report on Form 10-KSB (the "Annual Report") contains a discussion of certain of
the risks and uncertainties that affect our business. We refer you to the "Risk
Factors" on pages 22 through 37 of the Annual Report 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 Consolidated
Financial Statements and Notes set forth above in this Quarterly Report and in
the Annual Report.

(1) OVERVIEW

We develop and commercialize minimally invasive medical procedures that employ
our laser technologies and associated disposable products. We currently focus on
endovenous laser treatment of varicose veins using our proprietary technology
including our exclusive rights to U.S. Patent No. 6,398,777, (EVLT(R)). 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
through our patented EVLT(R) technology, 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 were the first to receive FDA clearance to
expand the application of EVLT(R) to other superficial veins in the lower
extremities. In July 2005, we received a Notice of Allowance from the U.S.
Patent and Trademark Office allowing a patent encompassing a proprietary marked
introducer sheath for use with our patented EVLT(R) laser treatment for varicose
veins.

EVLT(R) was a primary source of revenue in the three months and six months ended
June 30, 2005, and will continue to be our primary source of revenue for the
remainder of fiscal year 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 products and programs, 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.

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. During 2004,
we increased our number of sales representatives to 20. This represents a
significant investment in sales staff. Additionally, our current clinical
support organization employees 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 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.

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.

(2) RESULTS OF OPERATIONS

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

REVENUE

Diomed delivered revenue for the three months ended June 30, 2005 of $4,773,000,
increasing approximately $1,590,000, or 50%, from $3,183,000 for the same period
in 2004. Revenue from the EVLT(R) product line increased 69% over the same
period last year, including North America EVLT(R) growth of 94%, demonstrating
the continued and growing acceptance of EVLT(R) by the medical community and
patients alike.

For the three months ended June 30, 2005, approximately $2,451,000, or 51%, of
our total revenue was derived from laser sales, as compared to approximately
$1,855,000, or 58%, in the same period in 2004. In the three months ended June
30, 2005, approximately $2,322,000, or 49%, of our total revenues were derived
from sales of disposable fibers and kits, accessories and service, as compared
to approximately $1,327,000, or 42%, 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.

                                        2


<PAGE>


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 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 recent establishment of reimbursement codes
            for EVLT(R) by the American Medical Association and the Center for
            Medicare and Medicaid Services, effective January 1, 2005.

COST OF REVENUE AND GROSS PROFIT

Cost of revenue for the three months ended June 30, 2005 was $2,521,000,
increasing approximately $602,000, or 31%, from $1,918,000 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 material costs. Cost of revenue, as a
percentage of sales, decreased from 60% to 53% on a year-to-year basis.

Gross profit for the three months ended June 30, 2005 was $2,252,000, increasing
approximately $988,000 from $1,264,000 from the same period in 2004. On a
percent-of-sales-basis, the gross margin increased from 40% to 47%. The increase
in gross profit in the second 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.

OPERATING EXPENSES

RESEARCH AND DEVELOPMENT EXPENSES for the three months ended June 30, 2005 were
$356,000, a decrease of $17,000, or 5%, 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 three months ended June 30, 2005 were
$2,306,000, an increase of $754,000, or 49%, over 2004. The increase was driven
by a significant expansion in the size of the sales force of $144,000, higher
sales commissions resulting from the increased sales volume of $92,000, 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 June 30, 2005
were $2,093,000, an increase of $683,000, or 48%, from the same period in 2004.
The increase was primarily attributable to incremental legal fees of $367,000
which totaled $725,000 for the quarter, as well as Sarbanes-Oxley compliance of
$76,000and other administrative costs. Legal expenses included the continuing
cost of patent litigation against four competitors commenced during 2004 and the
theft of trade secrets litigation 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 has been completed.

LOSS FROM OPERATIONS

Loss from operations for the three months ended June 30, 2005 was $2,502,000, an
increase of approximately $433,000 from the same period in 2004, as incremental
gross profit was primarily offset by increased legal costs related to our patent
litigation.

NET LOSS

Net loss for the three months ended June 30, 2005 was $2,652,000, or ($0.14) per
share, compared to $2,080,000, or ($0.14) per share, for the same period in
2004.

$3,659,000, or 60%, in the same period in 2004. In the six months ended June 30,
2005, approximately $4,336,000, or 49%, of our total revenues were derived from
sales of disposable fibers and kits, accessories and service, as compared to
approximately $2,473,000, or 40%, 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:

COST OF REVENUE AND GROSS PROFIT

Cost of revenue for the six months ended June 30, 2005 was $4,814,000,
increasing approximately $951,000, or 25%, from $3,863,000 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 63% to 54% on a year-to-year basis.

Gross profit for the six months ended June 30, 2005 was $4,092,000, increasing
approximately $1,822,000 from $2,270,000 from the same period in 2004. On a
percent-of-sales-basis, the gross margin increased from 37% 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.

$3,664,000, an increase of $855,000, or 30%, from the same period in 2004. The
increase was primarily attributable to incremental legal fees of $411,000, as
well as Sarbanes-Oxley compliance of $76,000 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 six months ended June 30, 2005 was $4,932,000, an
increase of approximately $566,000 from the same period in 2004, as incremental
gross profit was primarily offset by increased legal costs related to our patent
litigation.

INTEREST EXPENSE, NET

Interest expense for the six months ended June 30, 2005 was $1,556,000, compared
to $22,000 for the same period in 2004. Interest expense in the six months ended

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 ($179,300 at June 30, 2005)
or 80% of eligible accounts receivable. The credit line bears interest at a rate
of 3% above Barclays' base rate of 4.75% at June 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 June 30, 2005 and 2004 there was
approximately $313,000 and $0, respectively outstanding under these credit
facilities.

(4) CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of the Company's financial condition, results of
operations, and cash flows are based on the Company's consolidated financial
statements. 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. 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.

(5) 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 No. 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 No. 123R.

                           PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Misappropriation Litigation vs. Vascular Solutions

On December 12, 2003, we filed a lawsuit in the United States Federal 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 Federal 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.

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 continuing to proceed with the discovery phase of this litigation. For
purposes of efficiency, this case has been consolidated with another case for
pretrial purposes as discussed below.

                                        7

<PAGE>


On January 6, 2004, we filed a lawsuit in the United States Federal 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 currently in 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 Federal 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 Federal
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, and our answer to the complaint is currently due on August 16, 2005.
Diomed intends to vigorously defend the lawsuit.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
