F-3 DIOMED HOLDINGS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MARCH 31, 2007 (UNAUDITED) (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. (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 2006 annual report on Form 10-KSB on March 20, 2007, which included audited consolidated financial statements for the year ended December 31, 2006, and included 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, 2006. (3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Our Annual Report on Form 10-KSB for the year ended December 31, 2006 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. F-4 DIOMED HOLDINGS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MARCH 31, 2007 (UNAUDITED) (b) 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: March 31, December 31, 2007 2006 ------------- ----------- Raw Materials $1,504,450 $1,571,135 Work-in-Process 1,368,775 797,934 Finished Goods 1,777,734 1,652,148 ---------- ---------- $4,650,959 $4,021,217 ========== ========== (c) DEFERRED REVENUE Deferred revenue at March 31, 2007 was as follows: March 31, 2007 ------------- Beginning balance $ 388,328 Additions 252,595 Revenue/release (225,736) --------- Ending balance $ 415,187 ========= (d) ACCOUNTING FOR STOCK-BASED COMPENSATION The Company maintains stock-based incentive plans, providing stock incentives to employees and directors. The Company grants options to employees and directors to purchase common stock at an option price equal to the market value of the stock at the date of grant. Effective January 1, 2006, the Company accounts for share-based payments in accordance with SFAS 123(R). Prior to the effective date of SFAS 123R, the Company applied APB 25 and related interpretations to stock option grants. APB 25 provided that the compensation expense relative to stock options was measured based on the intrinsic value of the stock option at date of grant. Under the modified prospective approach, SFAS 123R applies to new awards and to awards that were outstanding on January 1, 2006 that are subsequently modified, repurchased or cancelled. Under the modified prospective approach, compensation cost includes all share-based payments granted prior to, but not yet vested on, January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS 123, and compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant-date fair value estimated in accordance with the provisions of SFAS 123R. Compensation cost is recognized as expense over the requisite service period, which is generally the vesting period. Prior periods were not restated to reflect the impact of adopting the new standard. The weighted-average grant date fair value of options granted in 2007 and 2006 was $0.59 and $1.65, respectively. The intrinsic value of options outstanding and exercisable at March 31, 2007 was $442,343 and $45,496, respectively. The intrinsic value of options outstanding and exercisable at March 31, 2006 was $234,178 and $63,722, respectively. The Company used the market price of $1.44 and $2.52 versus the exercise price at March 31, 2007 and 2006, respectively. F-5 DIOMED HOLDINGS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MARCH 31, 2007 (UNAUDITED) The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions used for grants during the applicable period: Three Months Ended March 31, ----------------------------------------- 2007 2006 ------------------- ------------------ Risk-free interest rate 3.01 - 4.70% 3.01 - 4.37% Expected dividend yield --% --% Expected lives (in years) 5.6 - 5.8 years 1.6 - 5.9 years Expected volatility 85.2 - 88.5% 71.2 - 89.3% Expected volatility is based on a weighted average of the historical daily volatility of the Company's stock and peer company volatility commensurate with the expected life of the option. The average expected life used in 2006 was calculated using the simplified method under Staff Accounting Bulletin No. 107 which averages the contractual term of the option with the vesting term. The risk-free rate is based on the rate of U.S. Treasury zero-coupon issues with a remaining term equal to the expected life of option grants. The Company uses historical data to estimate pre-vesting forfeiture rates of 5%. (e) 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. For all periods presented, comprehensive loss consists of the Company's net loss, changes in the cumulative translation adjustment account, and unrealized gains (loss) on marketable securities. Comprehensive net loss for all periods presented is as follows: Three Months Ended March 31, ------------------------- 2007 2006 ----------- ----------- Net loss $(4,351,807) $(4,035,727) Unrealized holding gain (loss) on marketable securities 59 (200) Foreign currency translation adjustment (40,386) 38,621 ----------- ----------- Comprehensive loss $(4,392,134) $(3,997,306) =========== =========== (f) SHORT TERM INVESTMENTS Marketable 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. Marketable securities included in cash and cash equivalents and short term investments at March 31, 2007, all of which mature within one year, consist of the following: Unrealized Unrealized Amortized Cost Fair Value Gains Losses -------------- ---------- ---------- ---------- Money Market Funds $2,756,314 $2,756,314 $ -- $ -- Commercial Paper 3,016,916 3,017,275 359 -- ---------- ---------- ---- ---- $5,773,230 $5,773,589 $359 $ -- ========== ========== ==== ==== As Reported: Unrealized Unrealized Amortized Cost Fair Value Gains Losses -------------- ---------- ---------- ---------- Cash and Cash Equivalents $5,273,628 $5,273,919 $291 $ -- Marketable Securities 499,602 499,670 68 -- ---------- ---------- ---- ---- $5,773,230 $5,773,589 $359 $ -- ========== ========== ==== ==== F-6 DIOMED HOLDINGS, INC.

(g) RECENT ACCOUNTING PRONOUNCEMENTS In July 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes - An Interpretation of FASB Statement No. 109. This interpretation addresses the accounting for uncertainty in income taxes recognized in a company's financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. It prescribes a comprehensive model for recognizing, measuring, presenting and disclosing in the financial statements tax positions taken or expected to be taken in a tax return. It requires that only benefits from tax positions that are more-likely-than-not of being sustained upon examination should be recognized in the financial statements. These benefits would be recorded at amounts considered to be the maximum amounts more-likely-than-not of being sustained. At the time these positions become more-likely-than-not to be disallowed, their recognition would be reversed. This interpretation is effective for fiscal years beginning after December 15, 2006, with the cumulative effect of the change in accounting principle recorded as an adjustment to retained earnings. The Company adopted the provisions of FIN 48 effective January 1, 2007. The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Upon adoption of FIN 48 on January 1, 2007, the Company did not record any interest or penalties. The Company is subject to taxation in the UK, US and various state jurisdictions. The Company's tax years for 1998 and forward are subject to examination by the US tax authorities due to the carryforward of unutilized net operating losses. The Company's tax years for 2004 and forward are subject to examination by the UK tax authorities. The adoption of FIN 48 did not have a material impact on the financial condition, results of operations or cash flows. At January 1, 2007, the Company had US net operating loss ("NOL") carryforwards of approximately $46 million and foreign NOLs of approximately $20 million. At January 1, 2007, the Company had a net deferred tax asset of approximately $25 million related to these NOLs. Due to uncertainties surrounding the Company's ability to generate future taxable income to realize these assets, a full valuation has been established to offset the net deferred tax asset. Additionally, the future utilization of the US NOL carryforwards to offset future taxable income may be subject to a substantial annual limitation as a result of Section 382 ownership changes that may have occurred previously or that could occur in the future. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three year period. Since the Company's formation, the Company has raised capital through the issuance of capital stock which, combined with the purchasing shareholders' subsequent disposition of those shares, may have resulted in a change of control, as defined by Section 382, or could result in a change of control in the future upon subsequent disposition. If the Company has experienced a change in control at any time since the Company's formation, utilization of the Company's NOL carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL carryforwards before utilization. Any carryforwards that will expire prior to utilization as a result of such limitations will be removed from deferred tax assets with a corresponding reduction of the valuation allowance. Due to the existence of the valuation allowance, future changes in our unrecognized tax benefits related to NOLs will not impact the Company's effective tax rate. (4) 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 period ended March 31, 2006 includes $154,991 of non-cash preferred stock dividends accreted for future increasing rate dividends and $149,188 of preferred stock cash dividends earned during the period related to the September 30, 2005 private placement. Upon completion of the 2006 preferred stock financing, the Company exchanged the 2005 preferred stock for new preferred stock which does not currently accrue dividends. Therefore, there were no dividends recorded during the period ended March 31, 2007. F-7 DIOMED HOLDINGS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MARCH 31, 2007 (UNAUDITED) As a result of the losses incurred by the Company for the three month periods ended March 31, 2007 and 2006, 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.

As of March 31, 2007, Barclay's had provided a temporary increase in the overdraft facility up to approximately $331,000. The credit line bears interest at a rate of 2.5% above Barclays' base rate (5.25% at March 31, 2007) and borrowings are due upon collection of receivables from customers. As security for the line of credit, Barclay's Bank has a lien on all of the assets of Diomed, Ltd., excluding certain intellectual property. As of March 31, 2007, there was approximately $331,000 outstanding and at December 31, 2006, there was approximately $223,000 outstanding under this line of credit. (6) 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 three 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. The Company plans on settling any exercised employee stock options by issuing authorized but unissued shares. As of March 31, 2007, 275,400 options and other incentive stock awards were available for future grants under the 2003 Omnibus Plan. In addition, 11,138 options were available under the 2001 Plan and 1,123 options were available under the 1998 Plan as of March 31, 2007. A summary of stock option activity for the 2003 Omnibus Plan, the 2001 Plan and the 1998 Plan is as follows: Range of Number Weighted Average Weighted Average Exercise Price of Shares Exercise Price Remaining Life --------------- --------- ---------------- ---------------- Outstanding, December 31, 2006 $0.96 - $205.75 2,478,376 $4.63 Granted 0.81 - 0.81 643,000 0.81 Forfeited 4.68 - 4.68 (195,275) 4.68 --------------- --------- ----- Outstanding, March 31, 2007 $0.81 - $205.75 2,926,101 $3.78 8.12 =============== ========= ===== ==== Exercisable, March 31, 2007 $0.81 - $205.75 1,932,428 $5.04 7.46 =============== ========= ===== ==== F-8 DIOMED HOLDINGS, INC.

AngioDynamics generally denied the Company's allegations and sought a declaratory judgment of invalidity of the '777 patent. AngioDynamics also added certain counterclaims against the Company, including antitrust violations, patent misuse and other allegations, all arising from our obtaining and seeking to enforce the '777 patent. On March 4, 2004, the Company 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 the '777 patent. 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. At the parties' joint request, our patent cases involving AngioDynamics and Vascular Solutions were consolidated by the court. On December 21, 2005, the Company moved for summary judgment that the `777 patent is valid, enforceable, and infringed by both Vascular Solutions and AngioDynamics. On the same date, AngioDynamics and Vascular Solutions moved for summary judgment of noninfringement. On August 20, 2006, Judge Nathaniel Gorton issued a favorable ruling on the summary judgment motions. In particular, Judge Gorton rejected all of the various challenges raised by the defendants to the validity or enforceability of our '777 patent, and granted us summary judgment of validity and enforceability of the patent. Judge Gorton further denied all parties' cross-motions for summary judgment on infringement. Trial commenced on March 12, 2007 and on March 28, 2007, the jury found in favor of Diomed and against both defendants, both for inducing infringement and for contributory infringement of Diomed's patent, and awarded nearly $12.5 million in damages. The Company will not record this amount until final resolution of the appeal. In particular, the jury awarded $8.36 million against AngioDynamics and $4.1 million against Vascular Solutions. On March 30, 2007 Diomed filed a Motion for a Permanent Injunction against AngioDynamics and Vascular Solutions. In addition the parties have filed a series of post-judgment motions. Defendants have sought judgment as a matter of law and/or a new trial. Diomed has sought prejudgment interest and additional post-judgment damages. The post-trial motions are pending and will be heard by the court on May 22, 2007. On April 2, 2004, the Company 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. Total Vein Solutions answered the complaint, generally denying the Company's allegations and counterclaiming for declaratory judgment of non-infringement and invalidity of the EVLT(R) patent. The Company is in the discovery phase of this litigation. This case is also pending before Judge Gorton. On October 14, 2004, the Company filed a lawsuit in the United States 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. CoolTouch answered the complaint, generally denying the Company's allegations and counterclaiming for declaratory judgment of non-infringement and invalidity of the '777 patent. The Company is now proceeding with the discovery phase of this litigation. This case is also pending before Judge Gorton. F-10 DIOMED HOLDINGS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MARCH 31, 2007 (UNAUDITED) On March 29, 2007 the Company filed a lawsuit in United States District Court for the District of Massachusetts against Dornier Medtech America, Inc. seeking injunctive relief and damages for infringement of the '777 patent. This case is also pending before Judge Gorton. If the Company does not prevail in the appeal and infringement actions and is not be able to exclude third parties from using the Company's EVLT(R) technology, the EVLT(R) patent may be determined to be impaired and the Company's EVLT(R) revenue stream may be adversely affected. F-11 DIOMED HOLDINGS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MARCH 31, 2007 (UNAUDITED) 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 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' patents are unenforceable for inequitable conduct. The Company is now proceeding with the discovery phase of this litigation, which is scheduled to continue through mid-2007, with a trial date currently scheduled for October 2007. The Court held a claim construction tutorial and a hearing on claim construction issues on October 30, 2006 and issued a ruling on claims construction on November 20, 2006. The Company intends to continue to defend against the allegations against us in this case. OTHER 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. b) Commitments On August 5, 2005, the Company entered into a distribution agreement with Luminetx, pursuant to which Luminetx appointed the Company as a distributor and granted the Company the exclusive right to distribute and sell the Luminetx patented biomedical imaging system known as the VeinViewer(TM) Imaging System to 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. Luminetx agreed to supply the Company with a certain minimum number of VeinViewer(TM) systems for distribution by the Company at specified prices during the term of the distribution agreement, initially three years. During May 2007, the Company and Luminetx amended the agreement and revised the targeted number of VeinViewer(TM) systems to be purchased through December 31, 2007 and through April 30, 2008, to better reflect current market development and positioning strategies. The agreement was also amended so that both companies may sell to dermatologists who are not performing EVLT(R). If the Company fails to purchase the annual target number of VeinViewer(TM) systems prior to May 1, 2008, for any reason, Luminetx may terminate the distribution agreement with written notice. (9) STOCKHOLDERS' EQUITY At December 31, 2006, the Company had 19,448,728 shares of common stock outstanding. During the period ended March 31, 2007, the holders of 837.782 shares of preferred stock exchanged their shares of preferred stock into 8,371,782 shares of common stock. At March 31, 2007, the Company had 27,820,510 shares of common stock outstanding. On September 29, 2006, the Company issued 1,735.4347 shares of preferred stock, each share of which has a stated value of $11,500 per share. The Company issued 870.4348 of these shares to investors who purchased these shares for cash at a price of $11,500 per share, and the Company issued 864.9999 shares to investors who tendered 3,975,000 shares of preferred stock issued in 2005, all in accordance with the terms of a securities purchase agreement entered into with the investors in July 2006. Each share of preferred stock is exchangeable for 10,000 shares of common stock. At December 31, 2006, the Company had 1,735.4347 shares of preferred stock outstanding. During the period ended March 31, 2007, the holders of 837.782 shares of preferred stock exchanged their shares of preferred stock into 8,371,782 shares of common stock. At March 31, 2007, the Company had 898.2565 shares of preferred stock outstanding. (10) SUBSEQUENT EVENTS Subsequent to March 31, 2007, the holders of 202.6521 shares of preferred stock purchased in the September 29, 2006 private placement equity financing elected to exchange these share into common stock on a one-for10,000 basis, and accordingly the Company issued 2,026,521 shares of common stock to these holders. During May 2007, the Company and Luminetx amended the agreement and revised the targeted number of VeinViewer(TM) systems to be purchased through December 31, 2007 and through April 30, 2008 to better reflect current market development and positioning strategies. The agreement was also amended so that both companies may sell to dermatologists who are not performing EVLT(R). If the Company fails to purchase the annual target number of VeinViewer(TM) systems prior to May 1, 2008, for any reason, Luminetx may terminate the distribution agreement with written notice. F-12 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION 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 2006 Annual Report on Form SEC 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 19 through 34 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, we have incurred substantial costs to create or acquire our products. As of March 31, 2007, we had an accumulated deficit of approximately $95 million including $18.2 million in non-cash interest expense, $1,129,000 gain related to the adjustment of the market value of a warrant liability, and $735,000 in SFAS 123R compensation 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 we generate 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. 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. 1 EVLT(R) was the primary source of revenue in the first quarter of 2007, and will continue to be our primary source of revenue in 2007. We believe that EVLT(R) will achieve a high level of commercial acceptance due to its relativly 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, 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 private physician practices, hospitals, and clinics and focus on specialists in vascular surgery, interventional radiology, general surgery, interventional cardiology, phlebology, gynecology and dermatology. We primarily use a direct sales force to market our products in the United States and in select markets internationally, we also utilize 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. The VeinViewer(TM) became commercially available in April 2006. 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. Our management team focuses on developing and marketing solutions that address serious medical problems with significant market potential. 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. 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. (2) RESULTS OF OPERATIONS THREE MONTHS ENDED MARCH 31, 2007 COMPARED TO THE THREE MONTHS ENDED MARCH 31, 2006 REVENUE Diomed delivered revenue for the three months ended March 31, 2007 of $5,905,000, increasing approximately $1,329,000, or 29%, from $4,576,000 for the same period in 2006. Revenue from the EVLT(R) product line increased 23% over the same period last year, including growth of 40% in disposable procedure product revenue, demonstrating the continued and growing acceptance of EVLT(R) by the medical community and patients alike. In the three months ended March 31, 2007, approximately $1,845,000, or 31%, of our total revenue was derived from laser sales, as compared to approximately $1,770,000, or 39%, in the same period in 2006. In the three months ended March 31, 2007, approximately $4,060,000, or 69%, of our total revenues were from sales of disposable fibers and kits, accessories, service and VeinViewer(TM), as compared to approximately $2,807,000, or 61%, in the same period in 2006. 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, 2 - - the impact of increased acceptance of the EVLT(R) procedure and expanded reimbursement coverage by health care insurers. COST OF REVENUE AND GROSS PROFIT Cost of revenue for the three months ended March 31, 2007 was $3,225,000, increasing approximately $703,000, or 28%, from $2,523,000 for the three months ended March 31, 2006. The increase in cost of revenue in 2007 was primarily a result of increased revenues and increased indirect overhead costs. Gross profit for the three months ended March 31, 2007 was $2,680,000, increasing approximately $626,000, or 30% from $2,054,000 from the three months ended March 31, 2006. The increase in gross profit in 2007 was primarily a result of incremental sales volume. On a percent-of-sales basis, the gross profit of 45.4% increased fifty basis points compared with the gross margin of 44.9% in the prior year. We believe that gross profit as a percentage of sales may reach 60%, or more, assuming increases in sales volume and pricing adjustments that may occur after successful completion of the '777 patent litigation. OPERATING EXPENSES RESEARCH AND DEVELOPMENT EXPENSES for the three months ended March 31, 2007 of $415,000, increased by $61,000, or 17%, from the three months ended March 31, 2006. We expect R&D expenditures to remain relatively stable, as we continue to drive product functionality, cost improvements, and other enhancements. SELLING AND MARKETING EXPENSES for the three months ended March 31, 2007 of $3,136,000, increased $343,000, or 12%, over the three months ended March 31, 2006. The increase was driven by an expansion in the size of the sales force resulting in increased costs of $84,000 and higher sales commissions resulting from the increased sales volume, and increased sales and marketing expenditures in support of the sales efforts. We anticipate continued increased expenses resulting from the larger sales organization and increased commissions due to expected increases in volume. GENERAL AND ADMINISTRATIVE EXPENSES for the three months ended March 31, 2007 of $3,073,000, increased $1,014,000, or 49%, from the three months ended March 31, 2006. The increase was primarily attributable to increased legal costs during the trial phase of the `777 litigation. For the three months ended March 31, 2007, legal and patent related costs of $1,700,000 included $1,500,000 of trial related costs, and increased $900,000 compared to the three months ended March 31, 2006. These costs were partially offset by a decrease in our defense cost in the VNUS Medical Technologies, Inc. ("VNUS") litigation. LOSS FROM OPERATIONS As a result of the factors outlined above, the loss from operations for the three months ended March 31, 2007 was $3,944,000, increasing $792,000 from $3,152,000 for the three months ended March 31, 2006, as the expansion of our sales and marketing efforts during the quarter drove incremental revenue, which was offset by an increase in `777 patent trial related costs. OTHER EXPENSE, NET Other expense, net for the three months ended March 31, 2007 was $407,000, compared to other expense, net of $883,000 for the three months ended March 31, 2006. Other expense, net for the three months ended March 31, 2006 includes $770,000 for the non-cash, non-operating charge for the effect of the change in market value of warrants issued in the private placement financing completed on September 30, 2005. As a result of the financing which closed on September 29, 2006, the Company marked to market the warrant obligation for a final time and reclassified its mezzanine level preferred stock and warrant liability to permanent equity during the quarter ended September 30, 2006. 3 NET LOSS Net loss for the three months ended March 31, 2007 was $4,352,000 compared to $4,036,000 for three months ended March 31, 2006. The expansion of our sales and marketing efforts during the three months ended March 31, 2007 drove incremental revenue, resulting in increased gross margin, increased commissions, and increases in other sales and marketing costs. Also, included in the net loss is approximately $1.5 million in `777 patent trial costs. NET LOSS APPLICABLE TO COMMON STOCKHOLDERS Net loss applicable to common stockholders for the three months ended March 31, 2007 was $4,352,000, or $0.20 per share, compared to $4,340,000, or $0.22 per share, for the three months ended March 31, 2006. During 2006, we were required to pay cash dividends to holders of the 2005 preferred stock. These cash dividends amounted to $149,000 during the three months ended March 31, 2006. In addition, because the dividend percentage was considered below market for accounting purposes, we recorded an incremental non-cash dividend of $155,000 to reflect an effective interest rate of 16.5%. As a result of the preferred stock financing closed on September 29, 2006, the 2005 preferred stock was exchanged for the 2006 preferred stock, which does not accrue dividends unless a future dilutive financing is completed within certain terms. Therefore, we ceased paying or accreting these dividends on a prospective basis subject to the terms of the 2006 preferred stock. (3) LIQUIDITY, CAPITAL RESOURCES AND CAPITAL TRANSACTIONS CASH POSITION AND CASH FLOW We have financed our operations primarily through private placements of common stock and preferred stock and private placements of convertible notes and short-term notes and credit arrangements. We had cash and short-term investment balances of approximately $7,313,000 and $9,933,000 at March 31, 2007 and December 31, 2006, respectively. CASH USED IN OPERATIONS Cash used in operations for the three months ended March 31, 2007 was $2,689,000. The cash used in operations reflects the net loss of $4,352,000, which includes $1,462,000 in legal fees incurred in asserting our EVLT(R) patent, and was partially offset by non-cash charges such as $378,000 of non-cash interest and $164,000 for stock based compensation. The cash flow impact of the net loss was offset by changes in working capital items totaling approximately $870,000 primarily attributed to increased accounts payable and accrued expenses for patent litigation fees. CASH PROVIDED BY INVESTING Cash provided by investing activities for the three months ended March 31, 2007 was approximately $2,083,000, including proceeds from maturities of marketable securities of $2,150,000 as the Company limited reinvestment as a result of cash requirements, and purchases of computer and demonstration equipment of $67,000. CASH PROVIDED BY FINANCING Cash provided by financing activities for the three months ended March 31, 2007 was $108,000 of proceeds from our bank line of credit. BANK LINES OF CREDIT Diomed, Ltd., our United Kingdom-based subsidiary, utilizes an overdraft facility as well as an accounts receivable line of credit with Barclays Bank, limited to the lesser of (GBP)100,000 or 80% of eligible accounts receivable. As of March 31, 2007, Barclay's had provided a temporary increase in the overdraft facility up to approximately $331,000. The credit line bears interest at a rate of 2.5% above Barclays' base rate (5.25% at March 31, 2007) and borrowings are due upon collection of receivables from customers. As security for the line of credit, Barclay's Bank has a lien on all of the assets of Diomed Ltd., excluding certain intellectual property. As of March 31, 2007, there was approximately $331,000 outstanding and at December 31, 2006, there was approximately $223,000 outstanding under this line of credit. 4 FUTURE AVAILABILITY OF CREDIT As of March 31, 2007, other than the security under the Barclays Bank line of credit, our assets were not 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 March 31, 2007, two of the three investors who purchased debentures in 2004 continued to hold debentures of at least 10% of the original principal amount. Also, under the terms of the September 29, 2006 financing transaction, we agreed that so long as any investor owned at least 25% of the shares of preferred stock initially purchased, we would not incur indebtedness (other than ordinary course trade payables and installment loans) in excess of $1 million (including the Barclays Bank line of credit) without prior approval of the holders of the 65% of the outstanding 2006 preferred stock. EQUITY TRANSACTIONS During the period ended March 31, 2007, the holders of 837.782 shares of preferred stock exchanged their shares of preferred stock into 8,371,782 shares of common stock. At March 31, 2007, 898.2565 shares of preferred stock remain outstanding. At December 31, 2006, we had 19,448,728 shares of common stock outstanding and as a result of the conversions of preferred stock during the quarter, at March 31, 2007, we had 27,820,510 shares of common stock outstanding. COMMITMENT FOR LUMINETX DISTRIBUTION AGREEMENT On August 5, 2005, we entered into a distribution agreement with Luminetx, pursuant to which Luminetx appointed us as a distributor and granted the Company the exclusive right to distribute and sell the Luminetx patented biomedical imaging system known as the VeinViewer(TM) Imaging System to 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. Luminetx agreed to supply us with a certain minimum number of VeinViewer(TM) systems for distribution by us at specified prices during the term of the distribution agreement, initially three years. During May 2007, we and Luminetx amended the agreement and revised the targeted number of VeinViewer(TM) systems to be purchased through December 31, 2007 and through April 30, 2008 to better reflect current market development and positioning strategies. The agreement was also amended so that both companies may sell to dermatologists who are not performing EVLT(R). If we fail to purchase the annual target number of VeinViewer(TM) systems prior to May 1, 2008, for any reason, Luminetx may terminate the distribution agreement with written notice. (4) CRITICAL ACCOUNTING POLICIES 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 its 2006 Annual Report on Form 10-KSB with the Securities and Exchange Commission on March 20, 2007, which included audited consolidated financial statements for the year ended December 31, 2006, and included 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, 2006. 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. We have chosen accounting policies we believe are appropriate to report accurately and fairly our operating results and financial position, and we apply those accounting policies in a consistent manner. As discussed in Item 6, "Management's Discussion and Analysis of Financial Condition or Plan of Operation" of the Company's Annual Report on Form 10-KSB for the fiscal year ended December 31, 2006, we consider certain policies to be the most critical in the preparation of our consolidated financial statements because they involve the most difficult, or subjective judgments about the effect of matters that are inherently uncertain. 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. During the first quarter 2007, we adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes - An Interpretation of FASB Statement No. 109. This interpretation addresses the accounting for uncertainty in income taxes recognized in a company's financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. It prescribes a comprehensive model for recognizing, measuring, presenting and disclosing in the financial statements tax positions taken or expected to be taken in a tax return. It requires that only benefits from tax positions that are more-likely-than-not of being sustained upon examination should be recognized in the financial statements. These benefits would be recorded at amounts considered to be the maximum amounts more-likely-than-not of being sustained. At the time these positions become more-likely-than-not to be disallowed, their recognition would be reversed. This interpretation is effective for fiscal years beginning after December 15, 2006, with the cumulative effect of the change in accounting principle recorded as an adjustment to retained earnings. We adopted the provisions of FIN 48 effective January 1, 2007. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Upon adoption of FIN 48 on January 1, 2007, we did not record any interest or penalties. We are subject to taxation in the UK, US and various state jurisdictions. Our tax years for 1998 and forward are subject to examination by the US tax authorities due to the carryforward of unutilized net operating losses. The adoption of FIN 48 did not have a material impact on our financial condition, results of operations or cash flows. At January 1, 2007, we had US net operating loss ("NOL") carryforwards of approximately $46 million and foreign NOLs of approximately $20 million. At January 1, 2007, the Company had a net deferred tax asset of approximately $25 million related to these NOLs. Due to uncertainties surrounding our ability to generate future taxable income to realize these assets, a full valuation has been established to offset our net deferred tax asset. Additionally, the future utilization of our US NOL carryforwards to offset future taxable income may be subject to a substantial annual limitation as a result of Section 382 ownership changes that may have occurred previously or that could occur in the future. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three year period. Since our formation, we have raised capital through the issuance of capital stock which, combined with the purchasing shareholders' subsequent disposition of those shares, may have resulted in a change of control, as defined by Section 382, or could result in a change of control in the future upon subsequent disposition. If we have experienced a change in control at any time since our formation, utilization of the NOL carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL carryforwards before utilization. Any carryforwards that will expire prior to utilization as a result of such limitations will be removed from deferred tax assets with a corresponding reduction of the valuation allowance. Due to the existence of the valuation allowance, future changes in our unrecognized tax benefits related to NOLs will not impact our effective tax rate. 5 ITEM 3. CONTROLS AND PROCEDURES (a) Evaluation of disclosure controls and procedures. The Company's 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 -15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of March 31, 2007 and have concluded that, as of such date, the Company's disclosure controls and procedures in place are effective in ensuring that material information and other information requiring disclosure is identified and communicated on a timely basis. (b) Changes in internal control over financial reporting. During the period covered by this report, there have been no 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. 6 PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS '777 PATENT LITIGATION 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 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. AngioDynamics generally denied our allegations and sought a declaratory judgment of invalidity of the '777 patent. AngioDynamics 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. 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 the '777 patent. 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. At the parties' joint request, our patent cases involving AngioDynamics and Vascular Solutions were consolidated by the court. On December 21, 2005, we moved for summary judgment that the `777 patent is valid, enforceable, and infringed by both Vascular Solutions and AngioDynamics. On the same date, AngioDynamics and Vascular Solutions moved for summary judgment of noninfringement. On August 20, 2006, Judge Nathaniel Gorton issued a favorable ruling on the summary judgment motions. In particular, Judge Gorton rejected all of the various challenges raised by the defendants to the validity or enforceability of our '777 patent, and granted us summary judgment of validity and enforceability of the patent. Judge Gorton further denied all parties' cross-motions for summary judgment on infringement.7 Trial commenced on March 12, 2007 and on March 28, 2007, the jury found in favor of Diomed and against both defendants, both for inducing infringement and for contributory infringement of Diomed's patent, and awarded nearly $12.5 million in damages. In particular, the jury awarded $8.36 million against AngioDynamics and $4.1 million against Vascular Solutions. On March 30, 2007 Diomed filed a Motion for a Permanent Injunction against AngioDynamics and Vascular Solutions. In addition the parties have filed a series of post-judgment motions. Defendants have sought judgment as a matter of law and/or a new trial. Diomed has sought prejudgment interest and additional post-judgment damages. The post-trial motions are pending and will be heard by the court on May 22, 2007. 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. 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. This case is also pending before Judge Gorton. On October 14, 2004, we filed a lawsuit in the United States 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. CoolTouch answered the complaint, generally denying our allegations and counterclaiming for declaratory judgment of non-infringement and invalidity of the '777 patent. We are now proceeding with the discovery phase of this litigation. This case is also pending before Judge Gorton. On March 29, 2007 we filed a lawsuit in United States District Court for the District of Massachusetts against Dornier Medtech America, Inc. seeking injunctive relief and damages for infringement of the '777 patent. This case is also pending before Judge Gorton. 7 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. We are now proceeding with the discovery phase of this litigation, which is scheduled to continue through mid-2007, with a trial date currently scheduled for October 2007. The Court held a claim construction tutorial and a hearing on claim construction issues on October 30, 2006 and issued a ruling on claims construction on November 20, 2006. We intend to continue to defend against the allegations against us in this case. 8 ITEM 6.
