NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(Dollars in thousands, except per unit and per share data)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

The consolidated financial statements of ReGen Biologics, Inc. (“ReGen” or the “Company”) include accounts of the Company and its wholly-owned subsidiaries, RBio, Inc. (“RBio”) and ReGen Biologics AG (“ReGen AG”). Intercompany transactions and balances are eliminated in consolidation.

The consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, the accompanying consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position and the results of operations for the periods presented.

To date, sales of the Company’s products have been limited. ReGen will continue to require additional capital to further develop its products and further develop sales and distribution channels for its products around the world. Accordingly, the Company is still considered a development stage enterprise. Management believes that ReGen would emerge from the development stage when (a) the Company obtains either FDA clearance of the Collagen Scaffold device or premarket approval for the CMI® collagen meniscus implant (“CMI”), and either product is available for sale in the U.S. and (b) the Company begins to earn significant revenue from its principal operations.

ReGen currently operates as an orthopedic products company that develops, manufactures, and markets innovative tissue growth and repair products for U.S. and global markets. As discussed below, neither the Collagen Scaffold device nor the CMI, available for sale in certain markets outside the U.S. as the Menaflex™ collagen meniscus implant (“Menaflex”), is available for sale in the U.S. ReGen is managed and operated as one business segment. Accordingly, ReGen does not prepare financial information for separate product areas and does not have separate reportable segments as defined by Statement of Financial Accounting Standards (SFAS) No. 131, Disclosure about Segments of an Enterprise and Related Information.

For further information, refer to the consolidated financial statements and notes included in ReGen’s Annual Report on Form 10-K for the year ended December 31, 2007.

Risks and Going Concern Considerations

The future operating results of the Company may be affected by a number of risks and certain other factors. The Company’s future operating results are highly dependent upon its ability to obtain and maintain regulatory clearance and approvals for its products. Although Menaflex is marketed for sale and distributed in certain markets outside the U.S., it is not approved for sale in the U.S., and the Company makes no claim regarding its safety, effectiveness or its potential for FDA approval.

In December 2005 the Company submitted a 510(k) premarket notification to the U.S. Food and Drug Administration (the “FDA”) for the ReGen Collagen Scaffold for use in general surgical procedures for the reinforcement and repair of soft tissue where weakness exists, including, but not limited to, general soft tissue defects, hernias, and meniscus defects. The Collagen Scaffold reinforces soft tissue and provides a resorbable scaffold that is replaced by the patient’s own tissue. During the third quarter of 2006, the FDA provided the Company with a letter indicating the FDA’s initial determination that the device is not substantially equivalent or NSE to existing class II devices already in receipt of FDA clearance. The Company appealed the FDA’s NSE decision. Subsequently, the FDA provided a letter upholding the NSE decision and indicating that the Company may submit a new 510(k) for clearance of its Collagen Scaffold device with modified indications for use in the meniscus, as suggested by the Company, and supported by appropriate clinical data.

In December 2006 the Company submitted a revised 510(k) premarket notification to the FDA for the Collagen Scaffold. In March 2007, the Company received a letter from the FDA requesting additional information, which the FDA stated was necessary to complete its review of the 510(k) application. In June 2007 the Company responded to the FDA’s request and in the third quarter of 2007 the Company received an NSE letter from the FDA regarding the revised 510(k) submission. The Company has been pursuing appeal of the NSE decision through FDA administrative channels. Following discussions with the FDA, in July 2008, the Company submitted its latest 510(k) premarket notification to the FDA for the Collagen Scaffold.

13

The process of obtaining regulatory clearance or approval to market a medical device, particularly from the FDA, can be costly and time-consuming. There can be no assurance that such clearance or approval will be granted on a timely basis, if at all. If the 510(k) process continues to take longer than expected or the Collagen Scaffold device is not cleared, it will substantially delay our ability to commercialize the Collagen Scaffold and negatively impact our business. If the Collagen Scaffold device is not cleared through the 510(k), the Company still has the option of completing its submission to the FDA of the premarket approval application, or PMA for the CMI, although the Company does not foresee pursuing completion of the PMA at this time. The PMA process is typically more costly, lengthy and uncertain than the 510(k) clearance process.

In addition to regulatory related hurdles, in order to approach a position of positive operating earnings and cash flow, the Company will need to effectively address other operating issues, including for example establishing distribution channels and identifying third party reimbursement provisions for the surgeons and facilities that would be responsible for implanting the Company’s products. While the Company is actively working to address these issues, there is no guarantee that the Company will be able to effectively address these challenges in any given time frame.

As discussed in ReGen’s Annual Report on Form 10-K for the year ended December 31, 2007, all of the Company’s long-term debt (balance of $8,359 at June 30, 2008) becomes due and payable on December 31, 2009, and the Company’s Series A and Series C redeemable convertible preferred stock (liquidation preferences of $1,113 and $2,950, respectively) become redeemable at the option of not less than a majority of the holders in June 2009 and September 2010, respectively.

The Company will need to pursue additional financing in order to support ongoing operations, including meeting its future debt service requirements. While the Company has been successful in the past in obtaining the necessary capital to support its operations, there is no assurance that the Company will be able to obtain additional equity capital or other financing under commercially reasonable terms and conditions, or at all. In the three and six month periods ended June 30, 2008, the Company incurred net losses of $2,316 and $4,629, respectively and used $3,527 of cash in operating activities in the six months ended June 30, 2008. Beginning in the fourth quarter of 2007, the Company implemented measures to control costs that are within management’s discretion, including (but not limited to) costs such as consulting, advertising and promotion, personnel, other administrative costs and capital expenditures. At June 30, 2008, the Company had cash of $602 and net working capital of $573. As discussed in Note 6, on July 24, 2008, the Company completed a $2,539 private placement of convertible notes. Management expects the net proceeds from the private placement, combined with existing cash, will enable the Company to operate through November 2008. Management’s estimate may change, however, if actual results differ significantly from our expectations. Key assumptions that may affect our estimate of cash needs include (i) actual sales that may vary significantly from our expectations; (ii) the actual timeline of events with respect to our latest 510(k) submission to the FDA; (iii) decisions we make regarding our business objectives; and (iv) other developments in our business.  Management anticipates that additional cash will be required to support operations beyond November 2008. However, if unforeseen events occur, it is possible that additional cash may be needed before November 2008 to support operations. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. However, if additional capital is not obtained, the Company will not be able to continue as a going concern. The Company’s financial statements do not include any adjustments relating to the recoverability or classification of assets or the amounts or classification of liabilities that might result from the outcome of this uncertainty.

Adoption of New Accounting Pronouncements

In February 2008, the FASB issued FASB Staff Position No. FAS 157-2, Effective Date of FASB Statement No. 157. FSP No. 157-2, was effective upon issuance and delayed the effective date of SFAS No. 157 for nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), to fiscal years beginning after November 15, 2008. A discussion of SFAS 157 follows.

Effective January 1, 2008, the Company adopted SFAS No. 157, Fair Value Measurements. The standard provides enhanced guidance for using fair value to measure assets and liabilities. The standard also responds to investors’ requests for expanded information about the extent to which companies measure assets and liabilities at fair value, the information used to measure fair value, and the effect of fair value measurements on earnings. The standard applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. The standard does not expand the use of fair value in any new circumstances.

14

There were no gains or losses for the period ended June 30, 2008 included in earnings that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date. The Company’s money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Adoption of the provisions of SFAS No. 157 did not have a material effect on the Company’s consolidated financial statements.

Effective January 1, 2008, the Company adopted SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. The standard allows entities to voluntarily choose, at specified election dates, to measure many financial assets and financial liabilities (as well as certain non-financial instruments that are similar to financial instruments) at fair value (the “fair value option”). The guidance in SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007. The Company did not elect the fair value option for any financial assets or liabilities and, therefore, adoption of the provisions of SFAS No. 159 did not have a material effect on its consolidated financial statements.

In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles. This Statement identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles (GAAP) in the United States (the GAAP hierarchy). The Statement is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles. The Company does not expect adoption of SFAS No. 162 to have a significant impact on its consolidated financial statements.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, the reported amounts of revenues and expenses during the reporting period and related disclosures. The Company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.

Cash and Cash Equivalents and Investments

The Company considers all highly liquid investments purchased with a maturity of 90 days or less to be cash equivalents and as such has classified as cash equivalents cash held in a money market account, cash held in a sweep account, and investments in commercial paper and federal agency mortgage-backed securities that meet the Company’s classification criteria for cash equivalents. The Company held cash equivalents of $244 and $1,245, in a money market account and $216 and $902 in a sweep account as of June 30, 2008 and December 31, 2007, respectively. The Company also held cash equivalents in commercial paper of $0 and $955 at June 30, 2008 and December 31, 2007, respectively, and in federal agency mortgage-backed securities of $0 and $495, at June 30, 2008 and December 31, 2007, respectively. At June 30, 2008 and December 31, 2007, respectively, the Company held cash of $76 and $308 in a foreign account.

All investments are debt securities classified as held to maturity, and, accordingly, are carried at amortized cost, which approximates fair value. The cost of securities sold is based on the specific identification method, when applicable. At December 31, 2007, the Company had invested $100 in commercial paper. The Company did not have any material realized or unrealized gains or losses at June 30, 2008 or December 31, 2007.

Accounts Receivable

Accounts receivable are carried at estimated net realizable value. The Company records an allowance for doubtful accounts for all trade receivables that are not expected to be collected, usually those that are over 90 days past the invoice due date. The allowance for doubtful accounts was $2 and $3 at June 30, 2008 and December 31, 2007, respectively.

15

Inventories

Inventories are valued at the lower of actual cost or market, using the first-in, first-out (FIFO) method. Work in process is calculated by estimating the number of units that will be successfully converted to finished goods, based upon a build-up in the stage of completion using estimated labor inputs for each stage and historical yields reduced by estimated usage for quality control testing.

Inventory consists of the following:

	June 30, 2008		December 31, 2007
	(In thousands)
Raw material	$	21	$	24
Work in process		100		37
Finished goods		171		250
	$	292	$	311

Inventory was adjusted down $7 during the three and six months ended June 30, 2008, and $0 for the same periods in 2007. At both June 30, 2008 and December 31, 2007, 1% of total inventory is valued at below the Company’s cost. The Company estimates market value of inventory based upon sales activity within its various distribution channels. The Company’s production process has a high degree of fixed costs and due to the early stage of market acceptance for its products, sales and production volumes may vary significantly from one period to another. Consequently, in some periods sales and production volumes may not be adequate to provide for per unit costs that are lower than the current market price for the Company’s products.

Other assets

Prepaid expenses and other current assets consist of the following:

	June 30, 2008		December 31, 2007
	(In thousands)
Prepaid expenses	$	261	$	299
Escrow deposit		123		—
Interest and other receivables		38		32
Security deposit		5		5
	$	427	$	336

Other non-current assets consist of the following:

	June 30, 2008		December 31, 2007
	(In thousands)
Escrow deposit	$	302	$	—
Security deposit		100		100
Other assets		5		9
	$	407	$	109

The current escrow deposit was established to provide for payment of the retention bonus and related payroll taxes for non-executive employees that are expected to be paid in August 2008. The non-current escrow deposit was established to provide for payment of six months salary and benefits and related payroll taxes for three of the Company’s executive officers under certain termination scenarios. In accordance with the escrow agreement, any escrow funds not disbursed by December 31, 2009 will revert to the Company. The escrow deposits also include amounts to cover estimated escrow administration fees. See Note 2 for further information about the escrow arrangement and related commitments.

Accrued Expenses

Accrued expenses consist of the following:

	June 30, 2008		December 31, 2007
	(In thousands)
Accrued professional fees	$	272	$	238
Accrued wages and vacation		208		89
Accrued printing cost		21		15
Other accrued cost		29		10
	$	530	$	352

Foreign Currency Transactions

The Company has determined the functional currency of ReGen AG to be the U.S. dollar (USD). ReGen AG’s has cash accounts denominated in Swiss francs (CHF), euros and USD and its books and records are maintained in CHF. The Company remeasures ReGen AG’s nonmonetary assets and liabilities and related revenue and expenses using historical rates, other statement of operations accounts using average rates for the period, and monetary assets and liabilities using rates in effect at the balance sheet date. Foreign currency transaction gains or losses for the change in exchange rates between the USD and the foreign currency in which a transaction is denominated, including exchange gains and losses from remeasurement of the ReGen AG’s monetary assets and liabilities, are recognized currently in results of operations. Foreign currency transaction (gains) or losses included in the consolidated results of operations for the three month and six month periods ended June 30, 2008 approximated $14 and $(10), respectively, and $5 and $22, respectively, for the same periods in 2007.

Basic and Diluted Loss Per Share

Basic net loss attributable to common stockholders is calculated by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Shares that would be issued upon conversion of preferred stock or debt instruments are not included in the calculation of weighted average number of common shares outstanding during the period due to the Company’s net operating loss position. Dividends on preferred stock are not added to the net loss attributable to common stockholders until such dividends are declared. Due to the Company’s net loss position, all options, warrants and contingently issuable shares are anti-dilutive. Therefore, diluted and basic net loss per share are the same.

Stock-Based Compensation

Under the fair value recognition provisions of SFAS No. 123R, we recognize stock-based compensation net of an estimated forfeiture rate and only recognize compensation cost for those shares expected to vest, generally on a straight-line basis over the requisite service period of the award, usually the option vesting term of four years.

The Company uses the Black-Scholes model to estimate grant date fair value. For expected volatility, the Company uses its historical realized volatility, calculated using historical stock prices of the Company since June 2002. The expected term of options granted after January 1, 2006, is generally estimated to be seven years, given the contractual term of 10 years and vesting period of four years. The interest rate used in the pricing model is based on the U.S. Treasury yield curve in effect at the time of the grant on issues with remaining terms equal to the estimated expected term used in the model. In addition, the Company has estimated a forfeiture rate based on historical data and current assumptions. For options issued in our Series E Stock, we value these options based upon the equivalent fair value of options in common stock into which our Series E Stock is contingently convertible. We believe the fair value of our Series E Stock is equivalent to the fair value of our common stock on an as converted basis.

In the second quarter of 2008, the Company granted employees and directors options to purchase 109,065 shares of Series E Stock (or 10,906,500 shares of common stock after mandatory conversion of the Series E Stock), with an estimated weighted average grant date fair values of $13 per share (or $0.13 per share of common stock). Included in these grants were performance-based options to purchase 98,865 shares of Series E Stock (or 9,886,500 shares of common stock after mandatory conversion of the Series E Stock) with vesting that is contingent upon FDA clearance of the Company’s Collagen Scaffold device. There was no expense recognized in the second quarter related to these performance options. In the first quarter of 2007, the Company granted options to employees, officers and directors to purchase an aggregate of 4,375,642 shares of the Company’s common stock, with a per share weighted average fair value of $0.33. The Company did not grant options during the first quarter of 2008 or the second quarter of 2007.

17

During the second quarter of 2008, the Company granted options to non-employee consultants to purchase 8,445 shares of Series E Stock (or 844,500 shares of common stock after mandatory conversion of the Series E Stock), with an estimated weighted average grant date fair values of $12 per share (or $0.12 per share of common stock). Included in these grants were performance-based options for 485 shares of Series E Stock (or 48,500 shares of common stock after mandatory conversion of the Series E Stock) with vesting that is contingent upon FDA approval of the Company’s 510(k) for its Collagen Scaffold device. Also, during the second quarter of 2008, the Company granted options to a non-employee consultant to purchase 100,000 shares of common stock, with an estimated weighted average grant date fair values of $0.12 per share. During the first quarter of 2007, the Company granted options to non-employee consultants to purchase 100,000 shares of the Company’s common stock with an estimated per share fair value of $0.36 at the measurement date.

Amortization of compensation costs recognized for the three months ended June 30, 2008 and 2007, for grants awarded to employees and directors approximated $344 and $299, respectively. Amortization of compensation costs recognized for the six months ended June 30, 2008 and 2007, for grants awarded to employees and directors approximated $718 and $592, respectively. Amortization of compensation costs recognized for the three months ended June 30, 2008 and 2007 for grants awarded to non-employee consultants approximated $29 and $17, respectively. Amortization of compensation costs recognized for the six months ended June 30, 2008 and 2007 for grants awarded to non-employee consultants approximated $32 and $31, respectively. There has been no expense recognized for options with contingent vesting.

For the three and six month periods ended June 30, 2008, for services rendered during 2008, the Company issued to a vendor 3,750 and 7,500 shares, respectively, of Series E Stock. Related to this issuance the Company included the estimated fair value of $56 and $114 in its results of operations for the three and six month periods ended June 30, 2008, respectively. In connection with services rendered during 2007, the Company issued to a vendor 166,667 shares of restricted common stock in February 2008. Related to this issuance, the Company included the estimated fair value of $15 in its 2007 results of operations. On June 30, 2007, the Company issued 120,000 shares of its restricted common stock to a vendor for services rendered during the first six months of 2007, and recognized the estimated fair value of $29 and $47 in the Company’s results of operations for the three and six months ended June 30, 2007, respectively.

Effective March 2, 2007, the Company entered into a one year consulting agreement to retain the financial advisory services of Sanderling Ventures Management VI (Sanderling), affiliates of whom together beneficially own in excess of five percent of the Company’s common stock. In consideration for such services, the Company issued to Sanderling a warrant to purchase 2,000 shares of Series D Stock (or 200,000 common shares if the warrant is exercised after mandatory conversion of the Series D Stock) with the warrant having a five-year term and an exercise price of $42 per share (or $0.42 per common share if the warrant is exercised for shares of the Company’s common stock). Using the Black-Scholes model, the Company has estimated the fair value of the warrant to be approximately $69, which has been included as an expense in its 2007 results of operations. The warrants were exercisable for shares of Series D Stock upon issuance.

(2) COMMITMENTS AND CONTINGENCIES

From time to time the Company may be a defendant in lawsuits incidental to the Company’s business. Further, the nature of the Company’s operations subjects it to the inherent business risk of financial exposure to product liability claims. Currently, the Company is not a party to any material legal proceedings.

In January 2008, the Company committed to salary and benefit continuation payments through July 31, 2008 for its remaining U.S. non-officer employees, in the event that the Company terminates employment without cause (with “cause” defined as a material violation of Company policy as outlined in the Company’s employee handbook). The aggregate estimated cost for the salaries and benefits for January 1, 2008 through July 31, 2008 approximates $540. In addition the Company has committed to pay each U.S. non-officer employee a retention bonus equal to 15% of their respective annualized salaries, provided the employee remains actively employed through July 31, 2008. The retention bonus is forfeited if the employee resigns or employment is terminated for cause before July 31, 2008. However, if employment is terminated without cause before July 31, 2008, then the Company is obligated to pay the retention bonus. Aggregate retention bonuses under this program and estimated payroll taxes thereon approximate $119, which the Company expects to pay in August 2008. The Company accrued $102 at June 30, 2008 related to the retention bonus.

Effective June 27, 2008, management entered into an escrow arrangement to provide for payment of (i) the foregoing retention bonuses and related payroll taxes for non-executive employees and (ii) for six months salary and benefit continuation and related payroll taxes for three of the Company’s executive officers (approximating $300). In accordance with the escrow agreement, any funds not disbursed by December 31, 2009, will revert to the Company. The executive salaries and benefits will be continued in the event employment is terminated without cause (with “cause” defined as a material violation of Company policy as outlined in the Company’s employee handbook) or upon the failure of the Company to pay in full the regularly scheduled salary, withholding taxes and benefits of the designated executives as services are rendered by such executives.

In the fourth quarter of 2007 the Company responded to inquiries from the IRS and the state of California pertaining to options granted where the market price of the Company’s stock was higher than the exercise price of the options. In February 2008 and June 2008, the Company received follow-up inquiries from the IRS, to which it responded in May and June 2008, respectively. In July 2008, the Company received another follow-up inquiry to which it is in the process of responding.

On November 16, 2006, following our announcement that our management voluntarily initiated and conducted, and the Audit Committee of the Board of Directors oversaw, a review of the Company’s historical stock option granting and accounting practices, we received a letter from the Division of Enforcement of the U.S. Securities and Exchange Commission (the “SEC”) requesting that the Company preserve all documents concerning its granting of stock options to any of our executives or employees from January 2002 through the present and stating that the SEC intends to request production of such documents in the future. Subsequently, on November 20, 2006, the Company amended its quarterly and annual reports to include restated consolidated financial statements for the years ended December 31, 2005, 2004, 2003, the period from December 21, 1989 (inception) to December 31, 2005, and the quarters ended March 31, 2006 and June 30, 2006. At this time, while we intend to cooperate with the SEC inquiry, we cannot predict what consequences the SEC inquiry will have on the Company. The Company may be subject to regulatory fines or penalties or other contingent liabilities at the conclusion of the SEC’s inquiry.

The Company’s operations are subject to rigorous regulation by the FDA and numerous other federal, state, and foreign governmental authorities. Our manufacturing facility and our products are subject to continual review and periodic inspection by regulatory agencies. Failure to comply with FDA or other governmental regulations can result in fines, unanticipated compliance expenditures, recall or seizure of products, total or partial suspension of production and/or distribution, enforcement actions, injunctions, criminal prosecution, or other actions.

(3) CONCENTRATIONS OF RISK

The Company currently markets and sells two products. Our primary product, Menaflex (also known as the CMI), is a type I collagen implant designed to facilitate growth of new tissue to reinforce the existing meniscus tissue remaining after a partial meniscectomy procedure in the human knee. We also sell the SharpShooter Tissue Repair System (“SharpShooter”), a suturing device used to facilitate the surgical implantation of the Company’s collagen matrix products, as well as to perform other similar arthroscopic meniscal repair procedures.

Our products are marketed in the European Union (the “EU”), Switzerland, Turkey, and the Republic of South Africa, through ReGen AG. Currently, the Company has distributorship agreements with independent orthopedic device marketing organizations for the distribution of our products in Italy, Spain, Andorra, Poland, Turkey, the Republic of South Africa and the United Kingdom (the “U.K.”). SharpShooter also is marketed through a worldwide non-exclusive distribution agreement with Linvatec Corporation (Linvatec), a subsidiary of ConMed (NASDAQ: CNMD).

The Company is subject to inherent risks associated with international sales, such as changes in the economic, political, legal and business environments in the foreign countries in which we do business. The Company does not require collateral from its customers.

At June 30, 2008 and December 31, 2007, 10% and 1%, respectively, of the Company’s cash and cash equivalents balance was held in foreign currencies and 16% of current liabilities related to unsettled obligations denominated in foreign currencies, at each date. For the three and six month periods ended June 30, 2008, 22% and 20%, respectively, of the Company’s expenses resulted from transactions denominated in foreign currencies. For each of the three and six month periods ended June 30, 2007 and 2007, 18% of the Company’s expenses resulted from transactions denominated in foreign currencies.

(4) RELATED PARTY TRANSACTIONS

Amounts due to related parties, $4 at both June 30, 2008 and December 31, 2007, represent royalty payments due to an individual who is a shareholder and director.

The Company’s statement of operations for the six months ended June 30, 2008, includes $6 for a contribution to the same private foundation and $9 recognized in other income for website design services provided to an affiliate of the Company’s CEO. The Company’s statements of operations for the three and six months ended June 30, 2007, also include $4 representing reimbursable expenses due to a clinic owned by an individual who is a shareholder and director of the Company.

(5) STOCKHOLDERS’ EQUITY AND REDEEMABLE CONVERTIBLE PREFERRED STOCK

As of June 30, 2008, the Company has 165,000,000 authorized shares of common stock, of which 104,243,082 shares of common stock were outstanding. Also at June 30, 2008, the Company had reserved 9,066,464 shares of common stock for conversion of outstanding Series A Redeemable Convertible Preferred Stock (“Series A Stock”) and Series C Redeemable Convertible Preferred Stock (“Series C Stock”), 47,289,195 shares of common stock for the exercise of outstanding stock options and warrants and 500,000 shares for issuance to vendors for services to be rendered.

As of June 30, 2008, the Company has 500,000 shares of authorized Series D Convertible Preferred Stock (“Series D Stock”), of which 135,715 shares were issued and 200,939 shares were reserved for exercise of options and warrants. Each share of Series D Stock is mandatorily convertible into 100 shares of common stock upon the occurrence of certain events, such that a sufficient number of shares of common stock are available to effect the conversion. The Series D Stock is contingently convertible and was not convertible at June 30, 2008.

20

As of June 30, 2008, the Company has 500,000 shares of authorized Series E Preferred Stock (“Series E Stock”), of which 7,500 shares were issued, 448,771 shares were reserved for exercise of options, and 7,500 shares were reserved for issuance to vendors for services to be rendered. Each share of Series E Stock is mandatorily convertible into 100 shares of common stock upon the occurrence of certain events, such that a sufficient number of shares of common stock are available to effect the conversion. The Series E Stock is contingently convertible and was not convertible at June 30, 2008.

Redeemable Convertible Preferred Stock

During the first and second quarters of 2008 there were no conversions of Preferred Stock.  During the first quarter of 2007, holders of 10,776,909 and 4,463,289 shares of Series A Stock and Series C Stock, respectively, exercised their right to convert their shares to an equal number of shares of common stock. As a result of the Series C Stock conversions, $173 of unamortized issuance cost associated with the Series C Stock was recognized in the three months ended March 31, 2007 as deemed dividends to preferred stockholders for purposes of determining net loss attributable to common stockholders.  There were no conversions of Preferred Stock during the second quarter of 2007.

Contingently Convertible Preferred Stock

On March 2, 2007, March 30, 2007 and April 5, 2007, the Company completed the private placement of 71,429 shares, 47,619 shares, and 16,667 shares, respectively, of Series D Stock, resulting in aggregate proceeds net of issuance costs approximating $5,600 (the “Series D Financing”). Each share of Series D Stock is mandatorily convertible into 100 shares of the Company’s common stock, subject to adjustment for splits or other changes to the Company’s common stock, immediately upon either (i) amendment of the Company’s certificate of incorporation to increase the number of authorized shares of common stock sufficient to effect the conversion or (ii) the effectiveness of a reverse stock split of the Company’s common stock such that there are a sufficient number of shares of common stock available to effect the conversion, in both situations after taking into account all other shares of common stock outstanding or required to be issued upon the conversion of any preferred stock of the Company or the exercise of any options or warrants authorized by the Company. Either of such corporate actions is subject to the approval of our shareholders before they may be executed. The holders of Series D Stock each have one vote for each full share of common stock into which their shares of preferred stock are convertible on the record date for the vote. Holders of the Series D Stock do not have a contractual obligation to share in the losses of the Company. In the event of any liquidation, dissolution, or winding up of the Company, the holders of Series D Stock are entitled to receive a liquidation preference of $42 per share, plus any declared but unpaid dividends, and subject to adjustment for stock splits, combinations, or similar events involving the Series D Stock. Since the Series D Stock is mandatorily convertible upon the occurrence of certain corporate actions, the Series D Stock was issued with a contingent beneficial conversion feature that will be recognized as a reduction of net income attributable to common stockholders upon occurrence of the triggering event. The aggregate fair value of the contingent beneficial conversion feature on the dates of issue was approximately $1,480.

In connection with the Series D Financing the Company issued to the investors warrants to purchase 40,714 shares of the Company’s Series D Stock at an initial exercise price of $63 per share, or after mandatory conversion of the Series D Stock, 4,071,500 shares of the Company’s common stock at an initial exercise price of $0.63 per share. The warrants expire five years after issuance. The number of shares of Series D Stock or common stock to be issued upon exercise and the respective exercise prices are subject to adjustment for changes in the Series D Stock or common stock, such as stock dividends, stock splits, and similar changes. Also in connection with the Series D Financing, the Company issued to the investors options to purchase up to 135,715 shares of Series D Stock, exercisable for cash at $42 per share, or after mandatory conversion of the Series D Stock, 13,571,500 shares of the Company’s common stock at $0.42 per share. The respective exercise prices are subject to adjustment for stock splits and similar events. The options are exercisable for 15 days following public announcement of FDA clearance of the Company’s Collagen Scaffold device as a class II device and initially expired at the earliest of the 15th day after such public announcement, partial exercise of the option, or December 31, 2007. In October 2007, the Company extended the expiration date of the options to the earliest of the 15th day after such public announcement, partial exercise of the option, or December 31, 2008.

21

As of June 30, 2008 and December 31, 2007, both the options and warrants meet the criteria of EITF No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock, for classification as equity in the Company’s consolidated balance sheet.

Effective March 2, 2007, the Company entered into a one year consulting agreement to retain the financial advisory services of Sanderling Ventures Management VI (Sanderling), affiliates of whom together beneficially own in excess of five percent of the Company’s common stock. In consideration for such services, the Company issued to Sanderling a warrant to purchase 2,000 shares of Series D Stock (or 200,000 shares of common stock if the warrant is exercised after mandatory conversion of the Series D Stock into shares of Company common stock) with the warrant having a five-year term and an exercise price of $42 per share (or $0.42 per common share if the warrant is exercised for shares of Company common stock). Using the Black-Scholes model, the Company has estimated the fair value of the warrant to be approximately $69, which has been included as an expense in its 2007 results of operations.

On October 18, 2007, the Company’s Board of Directors authorized the filing of a Certificate of Designations, Preferences and Rights of Series E Convertible Preferred Stock of the Company (the “Certificate”) with the Secretary of State of the State of Delaware to designate and establish 500,000 shares of Series E Convertible Preferred Stock, par value $0.01 per share (“Series E Stock”). The Certificate was filed on October 19, 2007 and was effective upon filing. The Certificate provides, among other things, that each share of Series E Stock is mandatorily convertible into 100 shares of common stock of the Company immediately upon either (i) amendment of the Company’s certificate of incorporation to increase the number of authorized shares of common stock sufficient to effect the conversion or (ii) the effectiveness of a reverse stock split of the Company’s common stock such that there are a sufficient number of shares of common stock available to effect the conversion, in both situations after taking into account all other shares of common stock outstanding or required to be issued upon the conversion of any preferred stock of the Company or exercise of any options or warrants authorized by the Company. Either of such corporate actions is subject to the approval of our shareholders before they may be executed. The holders of Series E Stock each have one vote for each full share of common stock into which the shares of Series E Stock are convertible on the record date for the vote. Holders of the Series E Stock do not have a contractual obligation to share in the losses of the Company. In the event of any liquidation, dissolution, or winding up of the Company, the holders of Series E Stock are entitled to receive a liquidation preference of $9 per share, plus any declared but unpaid dividends, and subject to adjustment for stock splits, combinations, or similar events involving the Series E Stock.

At the 2008 annual meeting the Company’s shareholders approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to effect a one-for-fourteen, one-for-sixteen, one-for-eighteen or one-for-twenty reverse stock split, subject to the discretion of the Company’s Board of Directors before November 30, 2008. To date, the Board has not effected a reverse stock split and the Board is not obligated to effect a reverse stock split. Neither the Series D Stock nor the Series E Stock was convertible at June 30, 2008.

On April 5, 2008 the Company granted its non-employee directors, its employees, and certain consultants options to purchase a total of 116,550 shares of Series E Stock at an exercise price of $16 per share (or 11,655,000 shares of common stock at $0.16 per share, which equaled the market price of the Company’s stock on the grant date, if exercised after mandatory conversion of the Series E Stock). For one of the grants, to a consultant for 2,000 shares of Series E Stock (200,000 shares of common stock if exercised after mandatory conversion of the Series E Stock), 500 shares of Series E Stock (50,000 shares of common stock if exercised after mandatory conversion of the Series E Stock) were immediately vested at the grant date; the remainder vest quarterly, subject to continued service during each such quarter, on June 30, September 30, and December 31, 2008. Options granted to employees and to a consultant to purchase an aggregate of 15,200 shares of Series E Stock (1,520,000 shares of common stock if exercised after mandatory conversion of the Series E Stock) vest ratably over four years from the grant date. Options granted to employees, directors, and consultants to purchase an aggregated of 99,350 shares of Series E Stock (9,935,000 shares of common stock if exercised after mandatory conversion of the Series E Stock) vest ratably over four years beginning upon FDA clearance of the Collagen Scaffold device.

Also on April 5, 2008, the Company granted a consultant an option to purchase 100,000 shares of common stock at an exercise price of $0.16 per share, which equaled the market price of the Company’s stock on the grant date. One-half of the shares were immediately vested at the grant date and the remainder vest upon FDA clearance of the Collagen Scaffold device, provided such clearance is received in 2008.

On May 30, 2008, the Company granted a consultant an option to purchase 960 shares of Series E Stock at an exercise price of $17.50 per share (or 96,000 shares of common stock at $0.175 per share, which equaled the market price of the Company’s stock on the grant date, if exercised after mandatory conversion of the Series E Stock). For this grant, 460 shares were immediately vested at the grant date; the remainder vest ratably over four years from the grant date.

22

All of the foregoing grants were made outside of the Company’s stock option plans. Upon grant, the Company reserved 117,510 shares of Series E Stock and 100,000 shares of common stock for issuance upon exercise of the options.

(6) SUBSEQUENT EVENT

On July 24, 2008, the Company entered into a Subscription Agreement (the “Subscription Agreement”) among the Company and several investors named therein for the private placement of an aggregate principal amount not less than $2 million, but not more than $3 million of the Company’s unsecured convertible notes (the “Notes”).  Under the terms of the financing, the Company sold $2,539 aggregate principal amount of the Notes, which accrue interest at an annual rate of 8% and become due and payable on July 24, 2009.  At the option of the holders, the Notes may be converted into the Company’s Series F Convertible Preferred Stock, par value $0.01 per share (“Series F Stock”) at a price of $15 per share or into the Company’s common stock, par value $0.01 per share (“Common Stock”) at an initial conversion price of $0.15 per share if the Series F Stock has previously converted into Common Stock upon a Mandatory Conversion (as defined below).  In connection with the financing, the Company issued five year warrants equal to 25% of the shares into which the Notes may convert up to approximately 42,300 shares of Series F Stock, exercisable at a price of $1.00 per share or up to approximately 4,232,000 shares of Common Stock, exercisable at a price of $0.01 per share if the Series F Stock is converted into Common Stock upon a Mandatory Conversion. Participants in the financing included certain officers and directors of the Company and certain beneficial owners of more than 10% of the Company’s voting stock.

In connection with the financing, on July 21, 2008, the Company’s Board of Directors authorized the filing of a Certificate of Designations, Preferences and Rights of Series F Convertible Preferred Stock (the “Series F Certificate”) with the Secretary of State of the State of Delaware to designate and establish 270,000 shares of Series F Stock.  The Series F Certificate was filed on July 23, 2008 and was effective upon filing.  The Series F Certificate provides, among other things, that each share of Series F Stock is mandatorily convertible into 100 shares, initially, of Common Stock immediately upon either (i) amendment of the Company’s certificate of incorporation to increase the number of authorized shares of Common Stock sufficient to effect the conversion or (ii) the effectiveness of a reverse stock split of the Common Stock such that there are a sufficient number of shares of Common Stock available to effect the conversion, in both situations after taking into account all other shares of Common Stock outstanding or required to be issued upon the conversion of any preferred stock of the Company or exercise of any options or warrants authorized by the Company.  Either of such corporate actions is subject to the approval of the Company’s shareholders before they may be executed. At the 2008 annual meeting the Company’s shareholders approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to effect a one-for-fourteen, one-for-sixteen, one-for-eighteen or one-for-twenty reverse stock split, subject to the discretion of the Company’s Board of Directors before November 30, 2008. To date, the Board has not effected a reverse stock split and the Board is not obligated to effect a reverse stock split. The holders of Series F Stock each have one vote for each full share of common stock into which the shares of Series F Stock are convertible on the record date for the vote.  Holders of the Series F Stock do not have a contractual obligation to share in the losses of the Company.  In the event of any liquidation, dissolution, or winding up of the Company, the holders of Series F Stock are entitled to receive a liquidation preference of $15 per share, plus any declared but unpaid dividends, and subject to adjustment for stock splits, combinations or similar events involving the Series F Stock.

The holders of the Notes and the Series F Stock have certain terminable preemptive rights to purchase a pro rata share in a subsequent qualified financing by the Company.  The conversion rate of the Notes and the Series F Stock are subject to the anti-dilution rights of the holders of each.  The Company has agreed to register the Common Stock into which the shares of Series F Stock and the warrants will convert on one or more registration statements to be filed with the Securities and Exchange Commission upon request by the investors.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations (Dollars in thousands, except per share and per unit data)

The following discussion and analysis should be read in conjunction with the condensed consolidated financial statements and related notes included elsewhere in this Form 10-Q and the more detailed information contained in our Annual Report on Form 10-K for the year ended December 31, 2007. This section of the Form 10-Q contains forward-looking statements that involve risks and uncertainties, such as statements about our plans, objectives, expectations and intentions. We use words such as “anticipate,” “believe,” “expect,” “future” and “intend” and similar expressions to identify forward-looking statements. Our actual results could differ materially from those anticipated in these forward-looking statements for many reasons. You should not place undue reliance on these forward-looking statements, which apply only as of the date of this Form 10-Q.

Business

We are a development stage orthopedic products company that develops, manufactures and markets innovative tissue growth and repair products for U.S. and global markets. Our proprietary collagen matrix technology includes applications in orthopedics, general surgery, spine, cardiovascular and drug delivery. Some of these applications are marketable currently while others are in various stages of development. The Company’s first approved product using its collagen matrix technology is the Menaflex™ collagen meniscus implant device (also known as the CMI®), which is marketed for sale in the EU, Switzerland, Turkey, and the Republic of South Africa, through ReGenAG.

We have submitted a 510(k) premarket notification to the FDA for market clearance in the U.S. of the Collagen Scaffold device, which includes an application for the reinforcement and repair of meniscus defects. The 510(k) filing is necessary to obtain clearance to market the Collagen Scaffold as a medical device in the United States. The FDA will clear marketing of a medical device through the 510(k) process if it is demonstrated that the new product is substantially equivalent to other 510(k)-cleared products. The FDA has cleared for marketing, via the 510(k) premarket notification process, several products that we believe are similar in technology and intended use to the Collagen Scaffold and that are used in multiple medical specialties, including general surgery and orthopedics, for soft tissue reinforcement and repair. These devices have been cleared by the FDA as class II devices. We believe that it is appropriate for the FDA to regulate the Collagen Scaffold as a class II device subject to the 510(k) pre-market notification process.

Accordingly, relying in part on recently cleared similar devices as predicates, in December 2005 we submitted a 510(k) premarket notification to the FDA for the ReGen® Collagen Scaffold for use in general surgical procedures for the reinforcement and repair of soft tissue where weakness exists, including, but not limited to, general soft tissue defects, hernias, and meniscus defects. The Collagen Scaffold reinforces soft tissue and provides a resorbable scaffold that is replaced by the patient’s own tissue. During the third quarter of 2006, the FDA provided the Company with a letter indicating the FDA’s initial determination that the device is not substantially equivalent, or NSE, to existing class II devices already in receipt of FDA clearance. The Company appealed the FDA’s NSE decision. Subsequently, the FDA provided a letter upholding the NSE decision and indicating that the Company may submit a new 510(k) for clearance of its Collagen Scaffold device with modified indications for use in the meniscus, as suggested by the Company, and supported by appropriate clinical data.

In December 2006 we submitted a revised 510(k) premarket notification to the FDA for the Collagen Scaffold. In March 2007, we received a letter from the FDA requesting additional information, which the FDA stated was necessary to complete its review of the 510(k) application. In June 2007 we responded to the FDA’s request and in the third quarter of 2007 we received an NSE letter from the FDA regarding the revised 510(k) submission. The Company has been pursuing appeal of the NSE decision through FDA administrative channels. Following discussions with the FDA, in July 2008, the Company submitted its latest 510(k) premarket notification to the FDA for the Collagen Scaffold. If the revised 510(k) is unsuccessful, the Company intends to work diligently to pursue all alternatives available to it which would result in a class II designation for the Collagen Scaffold. We will continue to evaluate all levels of spending throughout the organization to support our ability to operate as long as possible, but it is likely that we will require additional financing before our appeal efforts are completed. There is no assurance that we will be able to raise such additional financing.

Prior to the filing of a 510(k) premarket notification for the Collagen Scaffold, which includes a meniscus application, we were pursuing premarket approval for the CMI in the U.S. The CMI has been the subject of a controlled, randomized, pivotal multicenter clinical trial, or MCT, and it is the subject of a modular premarket approval application, or PMA. Our current regulatory priority is to obtain FDA clearance for the Collagen Scaffold as a class II device through the 510(k) process. If we are not successful in gaining clearance for the Collagen Scaffold through the 510(k) process, we still have the option of completing our submission of the PMA for the CMI, although we do not foresee pursuing completion of the PMA at this time. We intend to continue to follow patients in the MCT, which will provide valuable scientific data on long-term patient outcomes in the meniscus.  If FDA clearance is obtained, we may make the Collagen Scaffold available in a flat sheet configuration, as well as in a semi-lunar shape designed for use in the meniscus, and potentially other configurations specifically designed to facilitate the reinforcement and repair of soft tissue in various sites within the body. There can be no assurance as to the outcome of our overall efforts to obtain either the FDA’s clearance of the Collagen Scaffold or, if we choose to pursue it, PMA approval of the CMI for sale in the U.S.

24

Our current strategy is to focus on the following initiatives:

• Obtain FDA clearance of the Collagen Scaffold as a class II device through the 510(k) process;

• Further develop our specialized distribution and marketing programs for the Menaflex and other ReGen products in Europe and certain other countries;

• Develop our specialized distribution, marketing, and training programs for the Collagen Scaffold and other ReGen products in the U.S.; and

• Conduct further research on selected product opportunities within our research and development pipeline.

Our long-term strategy is to capitalize on our proven collagen matrix technology by continuing to design, develop, manufacture and market our own products, as well as partner with others to develop and market products in targeted therapeutic areas. However, our ability to pursue this strategy is subject to the constraints of our current liquidity position. See Liquidity and Capital Resources.

To date, sales of our products have been limited. Although Menaflex is marketed for sale and distributed in certain markets outside the U.S., currently it is not cleared for sale or marketed in the U.S., and ReGen is making no claim regarding its safety, effectiveness or its potential for premarketing approval by the FDA. ReGen has exclusive worldwide rights to market Menaflex subject to relevant regulatory clearance in each market. In 2005 we created a wholly-owned subsidiary, ReGen AG to conduct our distribution activities outside the U.S. through local market distributors and a limited number of employees to be hired by the Company or ReGen AG. Currently, we have distributorship agreements with independent orthopedic device marketing organizations for distribution of our products in the U.K., Italy, Spain, Andorra, Poland, Turkey, and the Republic of South Africa. During 2008 our international priorities are growing sales of our products in current markets and evaluating distribution opportunities for our products in select new markets.

We also sell the SharpShooter® Tissue Repair System, or SharpShooter, a suturing device used to facilitate the surgical implantation of Menaflex, as well as to perform other similar arthroscopic meniscus repair procedures. SharpShooter is currently marketed through a worldwide non-exclusive distribution agreement with Linvatec Corporation (Linvatec), a subsidiary of ConMed (NASDAQ: CNMD), and outside the U.S., through ReGen AG.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. For example, when we value work in process inventory we use estimates to determine, among other factors, the number of units that will be successfully converted to finished goods. This and other estimates we make are often based on complex judgments, probabilities and assumptions that we believe to be reasonable, but that are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate and unanticipated events and circumstances may occur. It is also possible that other professionals, applying reasonable judgments to the same facts and circumstances, could develop and support a range of alternative estimated amounts. We also are subject to risks and uncertainties that may cause actual results to differ from estimated amounts, such as changes in the healthcare environment, competition, foreign exchange, litigation, legislation and regulation. These and other risks and uncertainties are discussed in the section entitled “Item 1A. Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007. All of these could significantly and adversely affect our business, prospects, financial condition or results of operations.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, if different estimates reasonably could have been used, or if changes in the estimate that are reasonably likely to occur could materially impact the financial statements. Management believes that there have been no significant changes during the three months ended June 30, 2008, to the items that we disclosed as our critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2007, including our adoption effective January 1, 2008, of SFAS No. 157, Fair Value Measurements, and SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, which did not have a material effect on our consolidated financial statements. For further discussion of our accounting policies see Note 3 “Summary of Significant Accounting Policies” of the Notes to Condensed Consolidated Financial Statements (Unaudited) and Note 3 “Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.

25

INCOME TAXES: We provide for income taxes in accordance with the asset and liability method, prescribed by SFAS No. 109, Accounting for Income Taxes. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. At December 31, 2007 the Company had a net operating loss carryforward of approximately $75,400 and a research and development tax credit carryforward of approximately $341. These carryforwards began to expire in 2005 and 2006, respectively. The utilization of net operating loss carryforwards may be limited due to changes in the ownership of the Company and its subsidiaries, and the effect of the reverse merger and recapitalization completed on June 21, 2002. A valuation allowance is required when it is more likely than not that a deferred tax asset will not be realized. As a result of evaluating all positive and negative evidence, we have established a full valuation allowance for the Company’s net deferred tax assets.

Effective January 1, 2007, we adopted FASB Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes. Adoption of FIN 48 did not have a significant impact on the Company’s consolidated financial statements. The Company files income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company is subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the years 2004 to 2007. In addition, the Company’s net operating loss carryforwards that relate to 1991 and forward are subject to adjustment by these tax authorities. At June 30, 2008, the Company has no unrecognized tax benefits requiring disclosure under FIN 48. The Company recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses. During the three and six month periods ended June 30, 2008 and 2007, the Company did not have any income tax related interest or penalties.

STOCK-BASED COMPENSATION EXPENSE: We account for stock based compensation in accordance with the fair value recognition provisions of SFAS No. 123R, Share Based Payment. Under the fair value recognition provisions of SFAS No. 123R, we recognize stock-based compensation net of an estimated forfeiture rate and only recognize compensation cost for those shares expected to vest, generally on a straight-line basis over the requisite service period of the award.

For stock issued to vendors for services, we recognize expense based on our stock price at the earlier of the date at which a performance commitment by the vendor exists or the date at which the vendor’s performance is complete. Expense recognized for non-employee options and for warrants issued in connection with equity transactions is measured based on management’s estimate of fair value and recognized on an accelerated basis over the respective vesting period.

Determining the appropriate fair value model and calculating the fair value of share-based payment awards require the input of highly subjective assumptions, including the expected life of the share-based payment awards and stock price volatility. Management determined that historical realized volatility calculated since the 2002 reverse merger is a reasonable indicator of expected volatility and future stock price trends. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management’s judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future. In addition, we are required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from our estimate, the stock-based compensation expense could be significantly different from what we have recorded in the current period.

We estimate fair value using the Black-Scholes model and the resulting values depend upon the assumptions we input into the model, including the risk-free interest rate, dividend yield, expected lives and expected volatility. We estimate the foregoing factors at the respective measurement dates of the grants. Upon examination of our historical pattern of option exercises in an effort to identify a discernable pattern, we concluded that there was not sufficient data on which to base an estimate of expected term. Consequently, the expected term of options granted after January 1, 2006, is generally estimated to be seven years, given the contractual term of 10 years and vesting period of four years. The interest rate used in the pricing model is based on the U.S. Treasury yield curve in effect at the time of the grant on issues with remaining terms equal to the estimated expected term used in the model. In addition, the Company has estimated a forfeiture rate based on historical data and current assumptions. For grants made after the Company’s merger with RBio, we estimate volatility using historical weekly closing prices of our stock since the merger through the closest date before the respective grant date.

For options issued in our Series E Stock, we value these options based upon the equivalent fair value of options in common stock into which our Series E Stock is contingently convertible. We believe the fair value of our Series E Stock is equivalent to the fair value of our common stock on an as converted basis.

26

We believe it is difficult to accurately measure the value of an employee stock option (see “Use of Estimates” above). The key factors used in the Black-Scholes model rely on assumptions we make of future uncertain events. Actual events may differ from our assumptions. Moreover, the Black-Scholes model ignores significant characteristics of compensatory options, such as their non-traded nature and lack of transferability. If the model permitted consideration of such unique characteristics the resulting estimate of fair value could be different.

INVENTORY VALUATION: Inventory is valued at the lower of cost or market. Market is based on current sales of product to existing customers reduced by an estimate of cost to dispose. At both June 30, 2008 and December 31, 2007, 1% of our inventory was carried at market. Work in process is calculated by estimating the number of units that will be successfully converted to finished goods, based upon a build-up in the stage of completion using estimated labor inputs for each stage, and historical yields reduced by estimated usage for quality control testing and for research and development.

To date commercial sales of our products have been inconsistent and our production efforts have been directed primarily toward development. Given the inconsistent and generally low volumes of commercial production to date, estimates and assumptions related to factors such as labor inputs and yields are based on a limited amount of historical data. Actual results may differ significantly from our estimates. We continually review the assumptions and estimates we use to value inventory and expect that our judgments regarding these estimates may change as commercial production volumes increase and additional data are available.

Certain components of inventory have limited shelf lives. Our inventory control policies include procedures to identify, evaluate, segregate and dispose of any nonconforming inventory, including materials or components that have passed specified expiration dates. Nonconforming inventory may be either scrapped for immediate disposal, used for demonstration or training, or used in research and development.

Recent Accounting Pronouncements

In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles. This Statement identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting principles (GAAP) in the United States (the GAAP hierarchy). The Statement is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles. The Company does not expect adoption of SFAS No. 162 to have a significant impact on its consolidated financial statements.

Results of Operations

Three and Six Months Ended June 30, 2008 Compared to Three and Six Months Ended June 30, 2007

REVENUE. Total revenue for the six months ended June 30, 2008 increased by $227 (64%) over the same period in 2007. The Company’s revenue from sales of our products approximated $222 and $556 for the three months and six months ended June 30, 2008, respectively, compared with $159 and $328, respectively, for the same periods in 2007. The approximate net increases of $63 (40%) and $228 (70%), respectively, resulted from increased sales of our Menaflex product, offset by decreases in SharpShooter sales. The remainder of our revenue is derived from royalties, which generally are due under a license agreement when our distributor, Linvatec, sells the SharpShooter product to a third party. Royalty revenue increased approximately $2 (17%) for the three months ended June 30, 2008 compared with the same period in 2007 and decreased approximately $1 (4%) for the six months ended June 30, 2008 compared with the same period in 2007. Historically, shipments of our products, and therefore our revenue, have been inconsistent for a number of reasons, including the supply requirements of our distributors and their anticipated rate of sales. Title of product passes to our direct sales customers FOB origin and to our distributors either FOB origin or FOB destination, depending upon the specific terms of the respective distributorship agreements. Our customers do not have a right to return the product other than for product defect issues.

For the three months and six months ended June 30, 2008, Menaflex sales approximated $144 and $452, respectively, compared to approximately $76 and $150, respectively, for the same periods in 2007, increases of approximately 89% and 201%, respectively. Selling prices for the Menaflex ranged from $1,050 to $2,600 per unit. Menaflex sales approximated 65% and 81%, respectively, of total sales for the three month and six month period ended June 30, 2008, compared with approximately 48% and 46%, respectively, for the same periods in 2007. During the three and six months ended June 30, 2008, we sold 87 and 280 Menaflex units, respectively, at average selling prices of $1,561 and $1,564 per unit, respectively, compared with 51 and 111 units, respectively, sold in the same periods of 2007 at average selling prices of $1,220 and $1,347 per unit, respectively.

27

SharpShooter sales in the three and six month periods ended June 30, 2008, approximated $78 and $104, respectively, compared with $83 and $178, respectively, for the same periods in 2007, representing decreases of $5 (6%) and $74 (42%), respectively. For the three month and six month periods ended June 30, 2008, SharpShooter sales to Linvatec, approximated $62 and $79, respectively, compared to $81 and $158, respectively, for the same periods in 2007, representing decreases of $19 (23%) and $79 (50%), respectively. SharpShooter sales to ReGen AG customers for the three and six month periods ended June 30, 2008 approximated $16 and $25, respectively, compared with $2 and $20, respectively, for the same periods in 2007, representing increases of $14 (700%) and $5 (25%), respectively. In the first quarter of 2008, the Company initiated a transition to a new vendor for assembly of a component of its SharpShooter product, which has resulted in a shortage of supply for this component. Management expects supply constraints to continue until the transition is complete.

COST OF GOODS SOLD. For the three and six months ended June 30, 2008, cost of goods sold approximated $137 and $280, respectively, compared with approximately $86 and $178, respectively, for the same periods in 2007, representing increases of approximately $51 (59%) and $102 (57%), respectively. The increases primarily relate to a higher volume of Menaflex sales. Menaflex cost of goods sold for the three and six months ended June 30, 2008 approximated $43 and $165 compared with approximately $21 and $43 for the same periods in 2007, increases of approximately $22 (105%) and $122 (284%). The average per unit cost of Menaflex units sold in the first half of 2008 approximated $433 compared with approximately $268 for the first half of 2007. The higher average per unit cost in 2008 is due to varying production volumes and manufacturing costs in the respective periods when the units were produced. At June 30, 2008 and 2007 all Menaflex units in inventory, as well as the Menaflex units sold during the first half of 2008 and 2007, were valued at cost, which was lower than market.

For the three and six months ended June 30, 2008, approximately $89 and $108 of cost of goods sold related to SharpShooter units sold compared with approximately $61 and $128 for the same period in 2007, representing an approximate increase of $28 (46%) for the three months ended June 30, 2008 and approximate decrease of approximately $20 (16%). The increase for the second quarter of 2008 is related to the recent change in supplier for certain SharpShooter components.  The decrease for the six month period is related to the lower volume of SharpShooter sales in the first quarter of 2008.

Due to a high degree of fixed costs in the production process, the early stage of market acceptance for our products, and the variability of commercial production volumes between periods, sales and commercial production volumes in a given period may not be adequate to provide for per unit costs that are lower than the current market price for our products. The positive gross margin achieved in the first six months of 2008 may not be indicative of a future trend.

RESEARCH AND DEVELOPMENT. Research and development expenses for the three and six months ended June 30, 2008 approximated $1,005 and $2,003, respectively, compared with approximately $1,193 and $2,256, respectively, for the same periods in 2007. Significant factors contributing to the net decrease of $188 (16%) for the comparative three month period include: (i) an approximate $40 decrease in compensation expense related to salary and staff reductions; (ii) an approximate $135 decrease in consulting, legal, and other professional fees and related costs associated with our 510(k) submissions to the FDA; (iii) an approximate $40 decrease in spending for maintenance of patents and other intellectual property; partially offset by (iv) an approximate $27 increase in non-cash compensation expense related to stock options granted to employees and non employees. Significant factors contributing to the net decrease of $253 (11%) for the comparative six month periods include: (i) an approximate $105 decrease in compensation expense related to salary and staff reductions; (ii) an approximate $96 decrease in consulting, legal, and other professional fees and related costs associated with our 510(k) submissions to the FDA; (iii) an approximate $78 decrease in spending for maintenance of patents and other intellectual property; partially offset by (iv) an approximate $26 increase in non-cash compensation expense related to stock options granted to employees and non employees

Currently, our research and development spending is primarily for clinical and regulatory activities and maintenance of patents and other intellectual property. During 2007, our research and development was focused largely on the conduct of our CMI MCT and related activities in the U.S. However, we also made progress on several other new product development efforts. We completed development of a CMI for the lateral meniscus and European regulatory authorities accepted an expanded CE mark for the CMI to include both the medial and lateral configurations. Our first sales of the lateral configuration occurred in the first quarter of 2007. Additionally, in 2007 we made progress in the ongoing refinement of our collagen matrix manufacturing processes focused on the increase in production yields and capacity. Lastly, we conducted early research on potential extended applications of our collagen matrix technology.

28

We believe that our proprietary collagen matrix technology has the potential to be used for the treatment of various injuries and degeneration of other tissue structures, as well as use as a carrier matrix for therapeutic agents for hard and soft tissue repair and new tissue growth. These applications are in various stages of development from proof of concept to preparation for submission to the FDA. We plan to continue to use outside resources for product research. We may, in the future, hire additional research and development employees. However, resource limitations have significantly curtailed our ability to conduct research and development in 2008 and we expect those activities will continue to be limited or further impaired if we are not successful in obtaining sufficient additional financing. See “Liquidity and Capital Resources.”

BUSINESS DEVELOPMENT, GENERAL AND ADMINISTRATIVE. Business development, general and administrative expenses for the three and six months ended June 30, 2008 approximated $1,313 and $2,782, respectively, compared with approximately $2,027 and $3,721, respectively, for the same periods in 2007. Significant factors contributing to the approximately $714 (35%) decrease for the comparative three month periods include: (i) an approximate $287 decrease in costs associated with our worldwide marketing and distribution initiatives, including consulting, advertising and promotion; (ii) an approximate $440 decrease for legal, accounting, printing and other professional services as a result of controls over discretionary spending; (iii) an approximate $48 decrease in compensation expense due to staff reductions; and (iv) an approximate $25 decrease in general and administrative costs such as travel as a result of controls over discretionary costs; partially offset by (v) an approximate $86 increase in non-cash compensation expense related to stock options and restricted stock granted to employees and non employees. Significant factors contributing to the approximately $939 (25%) decrease for the comparative six month periods include: (i) an approximate $645 decrease in costs associated with our worldwide marketing and distribution initiatives, including consulting, advertising and promotion; (ii) an approximate $452 decrease for legal, accounting, printing and other professional services as a result of controls over discretionary spending; and (iii) an approximate $55 decrease in general and administrative costs such as travel as a result of controls over discretionary costs; partially offset by (iv) an approximate $169 increase in non-cash compensation expense related to stock options and restricted stock granted to employees and non employees; and (v) an approximate $44 increase in compensation costs due to salary increases. We expect to continue controls over discretionary costs to conserve cash.

NON-OPERATING INCOME (EXPENSE). Non-operating income (expense) consists of interest and other income, and interest and other expense. Interest and other income approximated $13 and $45 for the three and six month periods ended June 30, 2008, respectively, compared with $121 and $212, respectively, for the same periods in 2007. The approximate decreases of $108 (89%) and $167 (79%), respectively, primarily related to lower cash and cash equivalent balances during the first half of 2008 compared to 2007. Interest and other expense approximated $110 and $188 for the three and six months ended June 30, 2008, respectively, compared with $121 and $235, respectively, for the same periods in 2007. The decrease for the respective three month periods is primarily due to lower interest rates on debt due to a related party. The decrease for the comparative six month periods is due to lower interest rates on debt due to a related party and to favorable foreign exchange rates.

Liquidity and Capital Resources

Cash and cash equivalents

The Company considers all highly liquid investments purchased with a maturity of 90 days or less to be cash equivalents and as such has classified as cash equivalents cash held in money market accounts, a sweep account and investments in commercial paper and federal agency mortgage-backed securities that meet our classification criteria for cash and cash equivalents. During 2007, the Company held investments in commercial paper and federal agency mortgage-backed securities. All investments were classified as held to maturity, and, accordingly, were carried at amortized cost, which approximates fair value. At June 30, 2008 approximately 10% of our cash and cash equivalents balance is held in foreign currencies. The effect on our 2008 condensed consolidated financial statements of re-measurement of the accounts of our Swiss subsidiary is immaterial.

Cash and cash equivalents and investments approximated $602 as of June 30, 2008 compared with approximately $4,108 as of December 31, 2007. The net decrease in cash and cash equivalents and investments is a result of cash used for operations, for equipment purchases, and for repayment of capital lease obligations.

Cash flows

The following table sets forth our sources and uses of cash for the six-month periods ended June 30, 2008 and 2007.

	June 30,
	2008			2007
	(In thousands)
Net cash used in operations	$	(3,527	)	$	(4,928	)
Net cash provided by (used in) investing activities		82			(329	)
Net cash (used in) provided by financing activities		(7	)		5,553
Effect of exchange rate changes on cash		46			(22	)
Net (decrease) increase in cash and cash equivalents	$	(3,406	)	$	274

Cash used in operating activities during the six months ended June 30, 2008 approximated $3,527, which resulted from the net loss of $4,629, adjusted to account for a net increase in accounts receivable, inventory and other assets of approximately $211, a net increase in accounts payable, accrued expenses and other liabilities of $443, together with adjustments of $870 for non-cash items, including depreciation, stock-based compensation and exchange loss related to re-measurement of our Swiss subsidiary’s financial statements.

During the six months ended June 30, 2008, we used investments in commercial paper of approximately $100, invested approximately $18 in property and equipment and repaid approximately $7 of our capital lease obligations.

Through June 30, 2008, we have incurred cumulative inception to date net losses of approximately $94,406 and used approximately $76,978 in cash for operating activities. The future operating results of the Company may be affected by a number of risks and certain other factors. The Company’s future operating results are highly dependent upon its ability to obtain and maintain regulatory clearance and approvals for its products. Although Menaflex is marketed for sale and distributed in certain markets outside the U.S., it is not approved for sale in the U.S., and the Company makes no claim regarding its safety, effectiveness or its potential for FDA approval. The Company has been pursuing appeal of an NSE decision related to its 510(k) submission to the FDA for market clearance in the U.S. of the Collagen Scaffold, which includes an application for the reinforcement and repair of meniscus defects. In July 2008, following its discussions with the FDA, the Company submitted to the FDA its latest 510(k) premarket notification for the Collagen Scaffold . The process of obtaining regulatory clearances or approvals to market a medical device, particularly from the FDA, can be costly and time-consuming. There can be no assurance that such clearances or approvals will be granted on a timely basis, if at all. If the 510(k) process continues to take longer than expected or the Collagen Scaffold device is not cleared, it will substantially delay our ability to commercialize the Collagen Scaffold and negatively impact our business. If the Collagen Scaffold device is not cleared through the 510(k), we still have the option to proceed with submission to the FDA of the PMA for the CMI, although we do not foresee pursuing completion of the PMA at this time. The PMA process is typically more costly, lengthy and uncertain than the 510(k) clearance process.

In addition to regulatory related hurdles, in order to approach a position of positive operating earnings and cash flow, the Company will need to effectively address other operating issues, including for example, establishing distribution channels and identifying third party reimbursement provisions for the surgeons and facilities that would be responsible for implanting the Company’s products. While the Company is actively working to address these issues, there is no guarantee that the Company will be successful or able to effectively address these challenges in any given time frame.

As discussed in our Annual Report on Form 10-K for the year ended December 31, 2007, all of the Company’s long-term debt (balance of $8,359 at June 30, 2008) becomes due and payable on December 31, 2009, and the Company’s Series A and Series C redeemable convertible preferred stock (liquidation preferences of $1,113 and $2,950, respectively) become redeemable at the option of not less than a majority of the holders in June 2009 and September 2010, respectively.

We will need to pursue additional financing in order to support ongoing operations, including meeting our future debt service requirements. While we have been successful in the past in obtaining the necessary capital to support our operations, there is no assurance that we will be able to obtain additional equity capital or other financing under commercially reasonable terms and conditions, or at all. Beginning in the fourth quarter of 2007 we implemented measures to control costs that are within management’s discretion, including (but not limited to) costs such as consulting, advertising and promotion, personnel, other administrative costs and/or capital expenditures. On July 24, 2008, the Company completed a $2,539 private placement of convertible notes. We expect the net proceeds from the private placement, combined with existing cash balances, will enable the Company to operate through November 2008, by which time we expect to receive a decision from the FDA regarding our latest 510(k) submission. Our estimate may change, however, if actual results differ significantly from our expectations. Key assumptions that may affect our estimate of cash needs include (i) actual sales that may vary significantly from our expectations; (ii) the actual timeline of events with respect to our 510(k) submission to the FDA; (iii) decisions we make regarding our business objectives; and (iv) other developments in our business. We anticipate that additional cash will be required to support operations beyond November 2008. However, if unforeseen events occur, it is possible that additional cash may be needed before November 2008 to support operations. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. However, if additional capital is not obtained, the Company will not be able to continue as a going concern. The Company’s financial statements do not include any adjustments relating to the recoverability or classification of assets or the amounts or classification of liabilities that might result from the outcome of this uncertainty.

Financing Transactions

On July 24, 2008, the Company entered into a Subscription Agreement (the “Subscription Agreement”) among the Company and several investors named therein for the private placement of an aggregate principal amount not less than $2 million, but not more than $3 million of the Company’s unsecured convertible notes (the “Notes”).  Under the terms of the financing, the Company sold $2,539 aggregate principal amount of the Notes, which accrue interest at an annual rate of 8% and become due and payable on July 24, 2009.  At the option of the holders, the Notes may be converted into the Company’s Series F Convertible Preferred Stock, par value $0.01 per share (“Series F Stock”) at a price of $15 per share or into the Company’s common stock, par value $0.01 per share (“Common Stock”) at an initial conversion price of $0.15 per share if the Series F Stock has previously converted into Common Stock upon a Mandatory Conversion (as defined below).  In connection with the financing, the Company issued five year warrants equal to 25% of the shares into which the Notes may convert for up to approximately 42,300 shares of Series F Stock, exercisable at a price of $1.00 per share or up to approximately 4,232,000 shares of Common Stock, exercisable at a price of $0.01 per share if the Series F Stock is converted into Common Stock upon a Mandatory Conversion.  Participants in the financing included certain officers and directors of the Company and certain beneficial owners of more than 10% of the Company’s voting stock.

In connection with the financing, on July 21, 2008, the Company’s Board of Directors authorized the filing of a Certificate of Designations, Preferences and Rights of Series F Convertible Preferred Stock (the “Series F Certificate”) with the Secretary of State of the State of Delaware to designate and establish 270,000 shares of Series F Stock.  The Series F Certificate was filed on July 23, 2008 and was effective upon filing.  The Series F Certificate provides, among other things, that each share of Series F Stock is mandatorily convertible into 100 shares, initially, of Common Stock immediately upon either (i) amendment of the Company’s certificate of incorporation to increase the number of authorized shares of Common Stock sufficient to effect the conversion or (ii) the effectiveness of a reverse stock split of the Common Stock such that there are a sufficient number of shares of Common Stock available to effect the conversion, in both situations after taking into account all other shares of Common Stock outstanding or required to be issued upon the conversion of any preferred stock of the Company or exercise of any options or warrants authorized by the Company.  Either of such corporate actions is subject to the approval of the Company’s shareholders before they may be executed. At the 2008 annual meeting the Company’s shareholders approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to effect a one-for-fourteen, one-for-sixteen, one-for-eighteen or one-for-twenty reverse stock split, subject to the discretion of the Company’s Board of Directors before November 30, 2008. To date, the Board has not effected a reverse stock split and the Board is not obligated to effect a reverse stock split. The holders of Series F Stock each have one vote for each full share of common stock into which the shares of Series F Stock are convertible on the record date for the vote.  Holders of the Series F Stock do not have a contractual obligation to share in the losses of the Company.  In the event of any liquidation, dissolution, or winding up of the Company, the holders of Series F Stock are entitled to receive a liquidation preference of $15 per share, plus any declared but unpaid dividends, and subject to adjustment for stock splits, combinations or similar events involving the Series F Stock.

The holders of the Notes and the Series F Stock have certain terminable preemptive rights to purchase a pro rata share in a subsequent qualified financing by the Company.  The conversion rate of the Notes and the Series F Stock are subject to the anti-dilution rights of the holders of each.  The Company has agreed to register the Common Stock into which the shares of Series F Stock and the warrants will convert on one or more registration statements to be filed with the Securities and Exchange Commission upon request by the investors.

On March 2, March 30, and April 5, 2007, we completed the private placement of approximately 71,429 shares, 47,619 shares, and 16,667 shares, respectively, of Series D Stock, $0.01 par value per share, resulting in aggregate proceeds net of issuance costs approximating $5,600. Each share of Series D Stock is mandatorily convertible into 100 shares of the Company’s common stock, subject to adjustment for splits or other changes to the Company’s common stock, immediately upon either (i) amendment of the Company’s certificate of incorporation to increase the number of authorized shares of common stock sufficient to effect the conversion or (ii) the effectiveness of a reverse stock split of the Company’s common stock such that there are a sufficient number of shares of common stock available to effect the conversion. Either of such corporate actions is subject to the approval of our shareholders before they may be executed. At the 2007 annual meeting our shareholders approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to effect a one-for-ten, one-for, twelve, one-for-fourteen, or one-for-sixteen reverse stock split, subject to the discretion of our Board of Directors. The Board did not effect a reverse stock split within the approved six-month timeframe and the Board was not obligated to effect a reverse stock split. The holders of Series D Stock each have one vote for each full share of common stock into which their shares of preferred stock are convertible on the record date for the vote. The holders of Series D Stock are entitled to non-cumulative dividends if and when such dividends are declared by the Board of Directors. No dividends have been declared to date. In the event of any liquidation, dissolution, or winding up of the Company, the holders of Series D Stock are entitled to receive a liquidation preference of $42 per share, plus any declared but unpaid dividends, and subject to adjustment for stock splits, combinations, or similar events involving Series D Stock. Since Series D Stock is mandatorily convertible upon the occurrence of certain corporate actions, the Series D Stock was issued with a contingent beneficial conversion feature that will be recognized upon occurrence of the triggering event.

31

In connection with the Series D Financing we issued to the investors warrants to purchase 40,714 shares of Series D Stock at an initial exercise price of $63 per share, or after mandatory conversion of the Series D Stock, 3,571,500 shares of the Company’s common stock at an initial exercise price of $0.63 per share. The warrants expire five years after issuance. The number of shares of Series D Stock or common stock to be issued upon exercise and the respective exercise prices are subject to adjustment for changes in the Series D Stock or common stock, such as stock dividends, stock splits, and similar changes. Also in connection with the Series D Financing, we issued to the investors options to purchase up to 135,715 shares of Series D Stock, exercisable for cash at $42 per share, or after mandatory conversion of the Series D Stock, 11,904,800 shares of the Company’s common stock at $0.42 per share. The respective exercise prices are subject to adjustment for stock splits and similar events. The options are exercisable for 15 days following public announcement of FDA clearance of the Company’s Collagen Scaffold device as a class II device and initially were to expire at the earliest of the 15th day after such public announcement, partial exercise of the option, or December 31, 2007. In October 2007, the Company extended the expiration date of the options to the earliest of the 15th day after such public announcement, partial exercise of the option, or December 31, 2008. On June 1, 2007 the Company registered with the SEC, the shares of common stock into which the Series D Stock would be convertible, as well as the shares of common stock that would be issuable upon exercise of the warrants and options, after mandatory conversion of the Series D Stock has occurred. As of June 30, 2008, both the options and warrants meet the criteria of EITF No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock, for classification as equity in the Company’s consolidated balance sheet.

Effective March 2, 2007, the Company entered into a one year consulting agreement to retain the financial advisory services of Sanderling Ventures Management VI (Sanderling), affiliates of whom together beneficially own in excess of five percent of the Company’s common stock. In consideration for such services, the Company issued to Sanderling a warrant to purchase 2,000 shares of Series D Stock (or 200,000 shares of the Company’s common stock if the warrant is exercised after mandatory conversion of the Series D Stock into Company common stock) with the warrant having a five-year term and an exercise price of $42 per share (or $0.42 per share of common stock if the warrant is exercised for shares of the Company’s common stock). Using the Black-Scholes model, the Company has estimated the fair value of the warrant to be approximately $69, which was expensed in its 2007 results of operations.

During the first quarter of 2007, holders of 10,776,909 and 4,463,289 shares of Series A Stock and Series C Stock, respectively, exercised their right to convert their shares to an equal number of shares of common stock.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Not required.

Item 4T. Controls and Procedures.

We maintain “disclosure controls and procedures” within the meaning of Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by the Company in the reports filed under the Exchange Act, such as in this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms. Our disclosure controls and procedures include controls and procedures designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures.

32

Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this Quarterly Report on the Form 10-Q, we evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures, which was done under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer. Included as Exhibits 32.1 and 32.2 to this Quarterly Report on Form 10-Q are certifications of our Chief Executive Officer and Chief Financial Officer, which are required in accordance with Rule 13a-14 of the Exchange Act. This Controls and Procedures section includes the information concerning the controls evaluation referred to in the certifications and it should be read in conjunction with the certifications for a more complete understanding of the topics presented. Based on the controls evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2008, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting. There has been no change in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the Company’s second quarter of 2008 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

Respectively, on October 23, 2007 and on November 2, 2007, the Company received information requests from the United States Internal Revenue Service (the “IRS”) and the state of California Franchise Tax Board regarding options granted where the market price of the Company’s common stock was higher than the exercise price of the options.  The Company responded to both inquiries in November 2007.  On February 11, 2008 and June 8, 2008 the Company received follow-up information requests from the IRS specifically regarding Section 162(m) of the Internal Revenue Code and further inquiries regarding the option grants, to which the Company responded in May and June 2008, respectively. On July 21, 2008, the Company received another follow-up inquiry from the IRS, to which it is in the process of responding.
