Overview

We are a clinical stage biopharmaceutical company focused on developing innovative product candidates for the treatment or prevention of a wide range of infections in hospital and non-hospital environments. Many of these infections have become increasingly difficult to treat because of the rapid rise in drug resistance. We have discovered and are developing a new class of non-antibiotic anti-infective compounds, which we have named AganocideŽ compounds. These compounds are based upon small molecules that are naturally generated by white blood cells when defending the body against invading pathogens. We believe that our Aganocide compounds could form a platform on which to create a variety of products to address differing needs in the treatment and prevention of bacterial and viral infections. In laboratory testing, our Aganocide compounds have demonstrated the ability to destroy all bacteria against which they have been tested. Furthermore, because of their mechanism of action, we believe that bacteria are unlikely to develop resistance to our Aganocide compounds.

Our business model is to develop our Aganocide compounds internally through phase II clinical trials for selected indications and enter into agreements with third parties for phase III clinical development and commercialization. We may also partner with certain indications at earlier stages of development.

In August 2006, we entered into a collaboration and license agreement with Alcon, that provided Alcon the exclusive rights to develop, manufacture and commercialize products incorporating the Aganocide compounds for applications in connection with the eye, ear and sinus and for use in contact lens disinfecting solutions. Under the terms of the agreement, Alcon agreed to pay an up-front, non-refundable, non-creditable technology access fee of $10.0 million upon the effective date of the agreement. In addition to the technology access fee, we are entitled to receive semi-annual payments from Alcon to support on-going research and development activities over the four year funding term of the agreement. The research and development support payments include amounts to fund a specified number of personnel engaged in collaboration activities and to reimburse for qualified equipment, materials and contract study costs. As product candidates are developed and proceed through clinical trials and approval, we will receive milestone payments. If the products are commercialized, we will also receive royalties on any sales of products containing the Aganocide compounds. Alcon has the right to terminate the agreement in its entirety upon nine months' notice, or terminate portions of the agreement upon 135 days' notice, subject to certain provisions. Both parties have the right to terminate the agreement for breach upon 60 days' notice.

Alcon is responsible for all of the costs that it incurs in developing the products using the Aganocide compounds. We announced the clearance of an Investigational New Drug (IND) application submitted by Alcon to the FDA to permit the clinical development of Novabay's NVC-422 for infection of the eye. The IND clearance has triggered the immediate payment of the first milestone of $1,000,000 from Alcon to Novabay. The achievement of the milestones and product commercialization is subject to many risks and uncertainties, including, but not limited to Alcon's ability to obtain regulatory approval from the FDA and Alcon's ability to execute its clinical initiatives. Therefore, we cannot predict when, if ever, the milestones specified in the Alcon agreement will be achieved or when we will receive royalties on sales of commercialized product.

In June 2007 we entered into a license agreement with Kinetic Concepts, Inc. ("KCI") under which KCI paid us a non-refundable technology access fee of $200,000. If products covered by this agreement are commercially launched, we will also receive royalty payments based on net revenues from sales by KCI of such products. We have not received any milestones of other payments under this agreement since the initial technology access fee.

On March 25, 2009, we announced that we entered into an agreement with Galderma S. A. to develop and commercialize our Aganocide compounds, which covers acne and impetigo and potentially other major dermatological conditions, excluding onychomycosis (nail fungus) and orphan drug indications. The agreement is exclusive and worldwide in scope, with the exception of Asian markets. Galderma will be responsible for the development costs of the acne and other indications, except in Japan, where they will be shared, and for the ongoing development program for impetigo, upon the achievement of a specified milestone. Galderma will also reimburse NovaBay for the use of its personnel in support of the collaboration. NovaBay retains the right to co-market products resulting from the agreement in Japan. In addition, NovaBay has retained all rights in other Asian markets outside Japan, and has exclusive rights to promote the products developed under the agreement in the hospital and other healthcare institutions in North America. Galderma will pay to Novabay certain upfront fees, ongoing fees, reimbursements, and milestone payments related to achieving development and commercialization of its Aganocide compounds. If products are commercialized under this agreement then NovaBay will receive royalties whose rates escalate as sales increase.

To date, we have generated no revenue from product sales, and we have financed our operations and internal growth primarily through the sale of our capital stock, and the technology access fee from Alcon. We are a development stage company and have incurred significant losses since commencement of our operations in July 2002, as we have devoted substantially all of our resources to research and development. As of March 31, 2009, we had an accumulated deficit of $26.9 million. Our accumulated deficit resulted from research and development expenses and general and administrative expenses. We expect to continue to incur net losses over the next several years as we continue our clinical and research and development activities and as we apply for patents and regulatory approvals.

Critical Accounting Policies and Estimates

Our financial statements have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported revenues and expenses during the reporting periods. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements giving due consideration to materiality. On an ongoing basis, we evaluate our estimates and judgments related to revenue recognition, income taxes, intangible assets, long-term service contracts and other contingencies. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2 of the Notes to Consolidated Financial Statements, included in Part I, Item 1 of this report, we believe that the following accounting policies are most critical to aid you in fully understanding and evaluating our reported financial results.

Revenue Recognition

License and collaboration revenue is primarily generated through agreements with strategic partners for the development and commercialization of our product candidates. The terms of the agreements typically include non-refundable upfront fees, funding of research and development activities, payments based upon achievement of certain milestones and royalties on net product sales. In accordance with Emerging Issues Task Force ("EITF") Issue No. 00-21, "Revenue Arrangements with Multiple Deliverables", we analyze our multiple element arrangements to determine whether the elements can be separated. We perform our analysis at the inception of the arrangement and as each product or service is delivered. If a product or service is not separable, the combined deliverables are accounted for as a single unit of accounting and recognized over the performance obligation period. We recognize revenue in accordance with SEC Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements", as amended by SAB No. 104 (together, SAB 104). In accordance with SAB 104, revenue is recognized when the following criteria have been met:
persuasive evidence of an arrangement exists; delivery has occurred and risk of loss has passed; the seller's price to the buyer is fixed or determinable; and collectibility is reasonably assured.

Assuming the elements meet the EITF No. 00-21 criteria for separation and the SAB 104 requirements for recognition, the revenue recognition methodology prescribed for each unit of accounting is summarized below:

Upfront Fees-We defer recognition of non-refundable upfront fees if we have continuing performance obligations without which the technology licensed has no utility to the licensee. If we have continuing involvement through research and development services that are required because our know-how and expertise related to the technology is proprietary to us, or can only be performed by us, then such up-front fees are deferred and recognized over the period of continuing involvement.

Funded Research and Development-Revenue from research and development services is recognized during the period in which the services are performed and is based upon the number of full-time-equivalent personnel working on the specific project at the agreed-upon rate. The full-time equivalent amount can vary each year if the contracts allow for a percentage increase determined by relevant salary surveys, if applicable. Reimbursements from collaborative partners for agreed upon direct costs including direct materials and outsourced, or subcontracted, pre-clinical studies are classified as revenue in accordance with EITF Issue No. 99-19, "Reporting Revenue Gross as a Principal versus Net as an Agent," and recognized in the period the reimbursable expenses are incurred. Payments received in advance are recorded as deferred revenue until the research and development services are performed or costs are incurred.

Milestones-Substantive milestone payments are considered to be performance bonuses that are recognized upon achievement of the milestone only if all of the following conditions are met: the milestone payments are non-refundable; achievement of the milestone involves a degree of risk and was not reasonably assured at the inception of the arrangement; substantive effort is involved in achieving the milestone; the amount of the milestone is reasonable in relation to the effort expended or the risk associated with achievement of the milestone; and a reasonable amount of time passes between the up-front license payment and the first milestone payment as well as between each subsequent milestone payment. If any of these conditions are not met, the milestone payments are deferred and recognized as revenue over the term of the arrangement as we complete our performance obligations.

Royalties-We recognize royalty revenues from licensed products upon the sale of the related products.

Research and Development Costs

We charge research and development costs to expense as incurred. These costs include salaries and benefits for research and development personnel, costs associated with clinical trials managed by contract research organizations, and other costs associated with research, development and regulatory activities. We use external service providers to conduct clinical trials, to manufacture supplies of product candidates and to provide various other research and development-related products and services. Research and development costs may vary depending on the type of item or service incurred, location of performance or production, or lack of availability of the item or service, and specificity required in production for certain compounds.

Patent Costs

We expense patent costs, including legal expenses, in the period in which they are incurred. Patent expenses are included as general and administrative expenses in our statements of operations. Patent costs may vary depending on the location, domestic of foreign, in which the patent is being secured.

Stock-Based Compensation

On January 1, 2006, we adopted the fair value recognition provisions of Statement of Financial Accounting Standards ("SFAS") No. 123R, "Share-Based Payment". SFAS No. 123R replaced SFAS No. 123 and superseded Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees" and related interpretations. Under the fair value recognition provisions of SFAS No. 123R, stock-based compensation expense is measured at the grant date for all stock-based awards to employees and directors and is recognized as expense over the requisite service period, which is generally the vesting period. We were required to utilize the prospective application method prescribed by SFAS No. 123R, under which prior periods are not revised for comparative purposes. Under SFAS No. 123R, forfeitures are estimated at the time of grant and reduce compensation expense ratably over the vesting period. This estimate is adjusted periodically based on the extent to which actual forfeitures differ, or are expected to differ, from the previous estimate. Under the prospective application transition method, non-public entities that previously used the minimum value method of SFAS No. 123 should continue to account for non-vested equity awards outstanding at the date of adoption of SFAS No. 123R in the same manner as they had been accounted for prior to adoption. SFAS No. 123R specifically prohibits pro forma disclosures for those awards valued using the minimum value method. The valuation and recognition provisions of SFAS No. 123R apply to new awards and to awards outstanding as of the adoption date that are subsequently modified. The adoption of SFAS No. 123R had a material effect on our financial position and results of operations. See Note 10 for further information regarding stock-based compensation expense and the assumptions used in estimating that expense.

Prior to the adoption of SFAS No. 123R, we valued our stock-based awards using the minimum value method and provided pro-forma information regarding stock-based compensation and net income required by SFAS No. 123. We did not recognize stock-based compensation expense in our statements of operations for option grants to our employees or directors for the periods prior to our adoption of SFAS No. 123R because the exercise price of options granted was generally equal to the fair market value of the underlying common stock on the date of grant.

We account for stock compensation arrangements with non-employees in accordance with SFAS No. 123R and EITF Issue No. 96-18, "Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services", which require that such equity instruments are recorded at their fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instruments vest. Non-employee stock-based compensation charges are amortized over the vesting period on a straight-line basis. For stock options granted to non-employees, the fair value of the stock options is estimated using a Black-Scholes-Merton valuation model.

The adoption of SFAS No.123R had a material effect on our financial position and results of operations. See Note 10 of the Notes to Consolidated Financial Statements, included in Part I, Item 1 of this report, for further information regarding stock-based compensation expense and the assumptions used in estimating that expense.

Income Taxes

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not that some portion or all of the deferred tax asset will not be recognized.

Results of Operations

Comparison of the Three Months Ended March 31, 2008 and March 31, 2009

License and Collaboration Revenue

Total license and collaboration revenue was $2.6 million for the three months ended March 31, 2009, compared to $1.5 million for the three months ended March 31, 2008. License and collaboration revenue consisted almost exclusively of amounts earned under the license and collaboration agreements with Alcon and Galderma for amortization of the upfront technology access fees, milestones, and other amounts that have been or will be reimbursed for the funding of research and development activities performed during the period. The upfront technology access fee of $10.0 million from Alcon is being amortized into revenue on a straight-line basis over the four year funding term of the agreement, through August 2010. The upfront fee of $1.0 million from Galderma is being amortized into revenue on a straight-line basis over the 20 month funding term of the agreement, through October 2010. The upfront technology access fee from KCI of $200,000 has been amortized on a straight-line basis over 18 months through December 2008.

To the extent we earn milestone payments under the Alcon and Galderma collaborations, we would expect revenues to increase. We expect to receive approximately $4.0 million during the 20 month initial period of the Galderma agreement, inclusive of the $1.0 million initial payment received in March 2009. However, we cannot predict if and when we will receive any milestone or royalty payments from these collaborations.

Research and Development

Total research and development expenses decreased by 47% to $1.4 million for the three months ended March 31, 2009 from $2.6 million for the three months ended March 31, 2008. The decrease was due to budget reductions at year end 2008 resulting in decreased headcount, and delayed research, development, and clinical expenses. We allocated $208,000 of overhead expenses to research and development for the first quarter of 2009.

We expect to incur increased research and development expenses in 2009 and in subsequent years as we continue to increase our focus on developing product candidates, both independently and in collaboration with Alcon and Galderma. In particular, we expect to incur ongoing clinical, chemistry, and manufacturing expenses during 2009 in connection with the common cold, dermatology, and catheter associated urinary tract infections programs.

General and Administrative

Total general and administrative expenses decreased by 6% to $1.6 million for the three months ended March 31, 2009 compared to $1.7 million for the three months ended March 31, 2008. Employee costs decreased as a result of staff reductions at year end 2008. Professional services costs increased primarily as a result of increased Sarbanes-Oxley implementation and year end audit costs.

We expect that general and administrative expenses will increase during 2009 and in subsequent years due to increasing public company expenses and business development costs and our expanding operational infrastructure. In particular, we expect to incur increasing legal, accounting, investor relations, equity administration and insurance costs in order to operate as a growing public company.

Other Income, Net

Other income, net decreased to $11,000 for the three months ended March 31, 2009 from $163,000 for the three months ended March 31, 2008. This decrease was primarily attributable to the liquidation of short term investments in the fourth quarter of 2008, resulting in less interest income in the first two months of 2009, until short-term investments were repurchased at the end of February 2009. Interest income relates primarily to interest earned on cash, cash equivalents and investments in marketable securities. See "Note 3-Short Term Investments."

We expect that other income, net will vary based on fluctuations in our cash balances and borrowings under equipment loans and the interest rate paid on such balances and borrowings.

Liquidity and Capital Resources

We have incurred cumulative net losses of $26.9 million since inception through March 31, 2009. We do not expect to generate significant revenue from product candidates for several years. Since inception, we have funded our operations primarily through the private placement of our preferred stock. We raised total net proceeds of $12.6 million from sales of our preferred stock in 2002 through 2006. In October 2007, we completed our IPO in which we raised a total of $20.0 million, or approximately $17.1 million in net cash proceeds after deducting underwriting discounts and commissions of $1.4 million and other offering costs of $1.5 million.

In August 2006, we entered into a collaboration and license agreement with Alcon. Under the terms of this agreement, we received an up-front technology access fee of $10.0 million in September 2006. Additionally, we are entitled to receive semi-annual payments each January and July over the four year term of the agreement to support on-going research and development efforts. In both January and July 2007, we received a payment of $1.4 million to support the performance of research and development activities throughout 2007. The Alcon agreement also provides for milestone payments upon the achievement of specified milestones in each field of use and royalty payments upon the sale of commercialized products. The aggregate milestone payments payable in connection with the ophthalmic, otic and sinus fields are $19.0 million, $12.0 million and $39.0 million, respectively. In January 2009, we received $1.0 million for the non-rejection of an IND application related to its otic indication. However, we cannot predict when, if ever, future milestones specified in the Alcon agreement will be achieved or when we will receive royalties on sales of commercialized products.

During April 2007, we entered into a master security agreement to establish a $1.0 million equipment loan facility with a financial institution. The purpose of the loan is to finance equipment purchases, principally in the build-out of our laboratory facilities. Borrowings under the loan are secured by eligible equipment purchased from January 2006 through April 2008 and will be repaid over 40 months at an interest rate equal to the greater of 5.94% over the three year Treasury rate in effect at the time of funding or 10.45%. There are no loan covenants specified in the agreement. As of March 31, 2009, we had an outstanding equipment loan balance of $836,291 carrying a weighted-average interest rate of 10.95%. The principal and interest due under the loan will be repaid in equal monthly installments through April 2011. As of March 31, 2009 there was $216,253 available for borrowing under this equipment loan facility.

In March 2009, we entered into a license agreement with Galderma. Under the terms of the agreement, we have received an initial upfront payment. In addition, Galderma will pay to Novabay certain upfront fees, ongoing fees, reimbursements, and milestone payments related to achieving development and commercialization of its AganocideŽ compounds.

Cash and Cash Equivalents

As of March 31, 2009, we had cash, cash equivalents, and short-term investments of $12.9 million compared to $12.1 million at December 31, 2008.

Cash Provided by (Used in) Operating Activities

For the three months ended March 31, 2008 cash used in operating activities of $(2.0 million) was primarily attributable to our research and development and general administrative expenses in running our company. For the three months ended March 31, 2009, cash provided by operating activities of $0.9 million, included the receipt of milestone and other cash payments from collaborative agreements, which more than offset the expenses in running our company.
