(1) BUSINESS AND BASIS OF PRESENTATION

A.P. Pharma, Inc. (the “Company,” “we,” “us” and “our”) is a specialty pharmaceutical company developing products using its proprietary Biochronomer^TM polymer-based drug delivery platform. This drug delivery platform is designed to improve the therapeutic profile of injectable pharmaceuticals by converting them from products that must be injected once or twice per day to products that need to be injected only once every one or two weeks.

The Company’s lead product candidate, APF530, is being developed for the prevention of both acute- and delayed-onset chemotherapy-induced nausea and vomiting (CINV). One of the most debilitating side effects of cancer chemotherapy, CINV is a leading cause of premature discontinuation of treatment. There is only one injectable 5-HT3 antagonist approved for the prevention of delayed-onset CINV, so this indication represents an area of particular unmet medical need. APF530 contains the 5-HT3 antagonist granisetron formulated in the Company’s proprietary Biochronomer™ drug delivery system, which allows therapeutic drug levels to be maintained for five days with a single subcutaneous injection. This five-day range is designed to cover the delayed phase of CINV, whereas currently available intravenous and oral formulations of granisetron are approved only for the prevention of acute-onset CINV. Granisetron was selected for APF530 because it is widely prescribed by physicians based on a well-established record of safety and efficacy.

In May 2009, we filed the original New Drug Application (NDA) seeking approval for APF530 with the U.S. Food and Drug Administration (FDA). The FDA issued a Complete Response Letter for APF530 in March 2010. We met with the FDA in February and March 2011 to clarify the work needed to resubmit the NDA. In September 2012, we resubmitted the NDA seeking approval for APF530 with the FDA. The FDA set a Prescription Drug User Fee Act (PDUFA) action date of March 27, 2013.

We own the worldwide rights to APF530 and are in the early stages of building the commercial infrastructure necessary to commercialize APF530 in the U.S. on our own. We are seeking corporate partners to commercialize APF530 in markets outside of the U.S.

The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All adjustments (all of which are of a normal recurring nature) considered necessary for a fair presentation have been included. We have evaluated subsequent events through the date that these financial statements were issued. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012 or for any other period. The condensed balance sheet as of December 31, 2011 has been derived from the audited financial statements as of that date, but it does not include all of the information and notes required by U.S. GAAP. These unaudited condensed financial statements and the notes thereto should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011, which was filed with the Securities and Exchange Commission (SEC) on March 26, 2012 (2011 10-K).

Liquidity

We have incurred significant operating losses and negative cash flows from operations and have an accumulated deficit of $175.9 million as of September 30, 2012. During 2011, we entered into two financing agreements, which provided us capital to fund operations. In April 2011, we entered into definitive agreements for a convertible note financing, which served as a bridge loan to fund the Company’s operations until additional financing was secured (see Note 9). The initial cash received from the bridge loan financing was approximately $1.3 million, net of issuance costs. In June 2011, we entered into definitive agreements for a private placement of units, which comprised of common stock and warrants (see Note 10). The unit financing, which closed in July 2011, provided the Company with approximately $22.8 million of proceeds, net of issuance costs. In May 2012, we received $3.0 million of cash through the issuance of additional convertible notes as a result of the purchasers who participated in the April 2011 convertible note financing fully

exercising their rights to purchase additional convertible notes. In July 2012, the Company closed a common stock financing whereby the Company received approximately $50.5 million of proceeds, net of issuance costs (see Note 10). As of September 30, 2012, we had cash and cash equivalents of $60.0 million. The Company believes that its current capital is sufficient to fund its planned operations through the anticipated product launch of APF530 in 2013, assuming FDA approval.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. We evaluate our critical accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. Our critical accounting policies and estimates are discussed in our 2011 10-K.

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2012, as compared to the recent accounting pronouncements described in our 2011 10-K, that we believe are of significance, or potential significance, to us.

(2) CASH EQUIVALENTS

Our available-for-sale securities as of September 30, 2012 and December 31, 2011 consisted of money market funds primarily containing U.S. government-backed securities, with original maturities of ninety days or less. The carrying value of our money market funds is included in cash equivalents and approximates their fair value. The Company’s bank accounts have been placed under a control agreement in accordance with the April 2011 convertible note financing (see Note 9).

(3) FAIR VALUE MEASUREMENTS

The three-tier fair value hierarchy utilized prioritizes the inputs used in measuring fair value as follows: Level 1) observable inputs such as quoted prices in active markets; Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and Level 3) unobservable inputs in which there is little or no market data, which require us to develop our own assumptions. The hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, we measure our available-for-sale securities at fair value. We used quoted prices in active markets (Level l) to measure the fair value of our cash equivalents on our Condensed Balance Sheets as of September 30, 2012 and December 31, 2011. Cash equivalents consist of highly rated money market funds with maturities of ninety days or less. Due to the high ratings and short-term nature of these funds, we consider the inputs used to value all cash equivalents as Level 1 inputs.

(4) NET LOSS PER SHARE

Basic and diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the applicable period. Diluted net loss per share excludes the effect of outstanding potentially dilutive securities because they are anti-dilutive. The following table shows the outstanding potentially dilutive options, warrants and convertible notes for the nine months ended September 30, 2012 and 2011 (in thousands):

	Nine Months  Ended September 30,
	2012		2011
Options outstanding		67,940		49,774
Warrants outstanding		84,377		84,127

Employee Stock Purchase Plan

We adopted an Employee Stock Purchase Plan (Purchase Plan) in 1997. Qualified employees may elect to have a certain percentage of their salary withheld to purchase shares of our common stock under the Purchase Plan. In June 2011, our stockholders authorized an increase in the number of shares reserved for issuance under the Purchase Plan by 500,000, for a total of 1,000,000 shares reserved at September 30, 2012. The purchase price per share is equal to 85% of the fair market value of the stock on specified dates. Sales under the Purchase Plan during the nine months ended September 30, 2012 and 2011 consisted of 58,571 and 49,486 shares at an average price of $0.21 and $0.20, respectively. Shares available for future purchase under the Purchase Plan were 472,605 at September 30, 2012.

(6) COMPREHENSIVE LOSS

Comprehensive loss for the periods reported was comprised solely of our net loss. The comprehensive loss for the three and nine months ended September 30, 2012 was $6.1 million and $15.6 million, respectively. The comprehensive loss for the three and nine months ended September 30, 2011 was $4.2 million and $7.6 million, respectively. There were no other changes in equity that were excluded from our net loss for all periods.

(7) DISCONTINUED OPERATIONS

Cosmeceutical and Toiletry Business

On July 25, 2000, we completed the sale of certain technology rights for our cosmeceutical and toiletry business to RP Scherer Corporation (RP Scherer), a subsidiary of Cardinal Health, Inc. Under the terms of the agreement with RP Scherer, we guaranteed a minimum gross profit percentage on RP Scherer’s combined sales of products to Ortho Dermatologics (Ortho) and Dermik Laboratories, Inc. (Dermik) (Gross Profit Guaranty). In July 2011, Valeant Pharmaceuticals announced that it was acquiring both Ortho and Dermik. The guaranty period initially commenced on July 1, 2000 and was to end on the earlier of: (i) July 1, 2010; or (ii) the end of two consecutive guaranty periods where the combined gross profit on sales to Ortho and Dermik equaled or exceeded the guaranteed gross profit (Two Period Test). The Gross Profit Guaranty expense totaled $944,000 for the first seven guaranty years and in those years profits did not meet the Two Period Test. Effective March 2007, in conjunction with a sale of assets by RP Scherer’s successor company to an Amcol International subsidiary (Amcol), a new agreement was signed between us and Amcol, in order to provide continuity of product supply to Ortho and Dermik. This new agreement potentially extends the Gross Profit Guaranty period an additional three years to July 1, 2013, unless it is terminated earlier with the Two Period Test. Amcol has indicated that its costs to produce the products differ from those it historically charged to the RP Scherer successor company. We have requested documentation from Amcol to substantiate actual costs. Until we receive confirmation of these amounts, we have accrued the full amount Amcol represents it is currently owed. As there is no minimum amount of Gross Profit Guaranty due, no accrual for the guaranty is estimable for future years. A liability of $1.1 million related to the current amount due under the Gross Profit Guaranty is recorded as accrued disposition costs on our Condensed Balance Sheet as of September 30, 2012. To date, we have not paid this amount, due to our inability to substantiate the amounts claimed by Amcol. As of the date of filing of this report, our dispute with Amcol over the Gross Profit Guaranty has been submitted to an independent accountant for resolution.

The cosmeceutical and toiletry business is reported as discontinued operations for all periods presented in our accompanying Condensed Statements of Operations.

Income (loss) from discontinued operations primarily represents the income (loss) attributable to changes in estimates of our cosmeceutical and toiletry business that was sold to RP Scherer on July 25, 2000, as follows (in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2012		2011			2012			2011
Cosmeceutical and Toiletry Business
Change in estimates for gross profit guarantees	$	128	$	(51	)	$	(6	)	$	(283	)

There was no material basic and diluted income (loss) per common share resulting from discontinued operations for the three and nine months ended September 30, 2012 and 2011.

(8) SIGNIFICANT AGREEMENTS

Merial Limited

In September 2009, we entered into a world-wide license and development agreement with Merial Limited (Merial), a leading animal health company, for a long-acting pain management product for cats and dogs. Under the terms of the agreement, we received a nonrefundable upfront license fee and performed reimbursable development services. In May 2011, we received notice of termination from Merial due to their concerns about the commercial potential of the product under development in the animal health market. We recognized no revenue related to development services provided to Merial in both the three months ended September 30, 2012 and 2011, and $0.0 and $0.5 million of revenue for the nine months ended September 30, 2012 and 2011, respectively. The remaining balance of deferred revenue related to the upfront license fee of $0.1 million was recognized as revenue in the quarter ended June 30, 2011, upon termination of the licensing agreement by Merial.

(9) CONVERTIBLE NOTES TO RELATED PARTIES

In April 2011, we entered into a Securities Purchase Agreement (Purchase Agreement) with certain institutional investors (Purchasers), including a fund affiliated with Kevin C. Tang, who is one of our directors, for a private placement of up to $4.5 million in Senior Secured Convertible Notes due 2021 (Notes). The Purchase Agreement provided for the Purchasers to purchase $1.5 million aggregate principal amount of Notes at the initial closing. Pursuant to the Purchase Agreement, the Purchasers had the option to purchase an additional $3.0 million aggregate principal amount of Notes at any time until May 2, 2013 (Purchase Option). The Notes are convertible into shares of the Company’s common stock at a rate of 25,000 shares for every $1,000 of principal and accrued interest due under the Notes (Conversion Shares).

The cash received from the initial closing of the Note financing, which resulted in the issuance of $1.5 million aggregate principal amount of Notes, was approximately $1.3 million, net of issuance costs. In May 2012, the Purchasers exercised their Purchase Option in full, and we received $3.0 million of cash through the issuance of the remaining $3.0 million aggregate principal amount of Notes. As a result of the exercise of the Purchase Option, the Purchasers have purchased the full amount of Notes that the Company was obligated to sell under the Purchase Agreement. If the $4.5 million principal amount of Notes is converted, the Company would issue 112.5 million shares of its common stock.

The Notes are secured by substantially all of the assets of the Company, including placing our bank accounts under a control agreement. The Notes initially bore interest at 20% per annum, payable quarterly in cash or in additional principal amount of Notes at the election of the Purchasers. In June 2011, the Notes were amended to reduce the interest rate to 6% per annum effective July 1, 2011. The Notes mature on May 2, 2021; however, the holders of the Notes may require prepayment of the Notes at any time beginning on or after May 2, 2012, at each holder’s option.

There is no right to convert the Notes to the extent that, after giving effect to such conversion, the holder would beneficially own in excess of 9.99% of the Company’s outstanding common stock. Each holder of the Notes can increase or decrease this beneficial ownership conversion limit by written notice to the Company, which will not be effective until 61 days after delivery of the notice.

As of September 30, 2012, the Company was in compliance with all debt-related covenants under the Notes. Upon the occurrence of an event of default under the Notes, the holders of the Notes have the right to require the Company to redeem all or a portion of their Notes.

Pursuant to the Purchase Agreement, the Company filed a registration statement on Form S-1 registering for resale 69.6 million shares underlying the Notes. The registration statement was declared effective on July 29, 2011. The Purchasers have agreed to waive their right to require the Company to register the additional shares underlying the Notes until they provide notice otherwise.

Concurrent with the approval of the offer and sale of the Notes, our board of directors approved the termination of the Company’s Preferred Shares Rights Agreement (Rights Agreement), effective immediately prior to the Purchase Agreement’s initial closing date.

The Notes contain an embedded conversion feature that was in-the-money on both issuance dates. Based on an effective fixed conversion rate of 25,000 shares for every $1,000 of principal and accrued interest due under the Notes, the total conversion benefit at issuance exceeded the loan proceeds. Therefore, a full debt discount was recorded in an amount equal to the face value of the Notes on the issuance dates, and the Company began amortizing the resultant debt discount over the respective 10-year or remaining term of the Notes. During the three and nine months ended September 30, 2012, accrued interest of approximately $51,000 and $98,000 was paid-in-kind and rolled into the principal balance of the Notes, which resulted in an additional full debt discount for the respective periods. For the three and nine months ended September 30, 2012, interest expense relating to the stated rate of the Notes was approximately $70,000 and $145,000, respectively. Interest expense relating to the amortization of debt discount for the three and nine months ended September 30, 2012 was approximately $125,000 and $262,000, respectively.

As of September 30, 2012, the carrying value of the Notes was approximately $365,000, which is comprised of the $4,672,000 principal amount of the Notes outstanding, less debt discount of $4,307,000. Accrued interest on the principal balance was $70,000 at September 30, 2012.

(10) STOCKHOLDERS’ EQUITY

Amendments to Articles of Incorporation

In June 2011, we amended our certificate of incorporation to increase the number of shares of authorized common stock to 1,500,000,000, par value $0.01 per share. Prior to the amendment, the number of shares of authorized common stock was 100,000,000, par value $0.01 per share. The certificate of amendment was approved by a majority of our stockholders on June 29, 2011.

Stock Plans

At our annual meeting of stockholders in June 2011, our stockholders approved an amendment to our 2007 Equity Incentive Plan to increase the maximum number of shares of common stock available for grant by 90,000,000 shares of common stock, resulting in an aggregate of 95,000,000 shares of common stock authorized for issuance pursuant to awards granted under our 2007 Equity Incentive Plan. The stockholders also approved an amendment to our 1997 Employee Stock Purchase Plan to increase the number of shares of common stock reserved for issuance under the plan by 500,000, for a total of 1,000,000 shares reserved as of September 30, 2012.

2011 Private Placement

In June 2011, the Company entered into a securities purchase agreement with certain purchasers (2011 Securities Purchase Agreement), pursuant to which the Company agreed to sell for an aggregate price of $24.0 million, 160,000,006 shares of its common stock (2011 Shares) and warrants to purchase 80,000,005 shares of its common stock (Warrants) at an exercise price of $0.18 per share (2011 Private Placement). The 2011 Private Placement closed on July 1, 2011. For each share purchased, the investors received one Warrant to purchase 0.5 shares of common stock (together with a share, a Unit), at a purchase price of $0.15 per Unit. The Warrants were immediately exercisable and expire on the fifth anniversary of the closing date of July 1, 2011. The Warrants may be exercised for cash only or, if a registration statement is not then effective and available for the resale of the shares of common stock issuable upon exercise of the Warrants, by surrender of such Warrant, or a portion of such Warrant, by way of cashless exercise. There is no right to exercise the Warrants to the extent that after giving effect to such exercise the holder would beneficially own in excess of 9.99% of our outstanding shares of common stock (or such other limit as may be designated by any particular purchaser). Each holder of the Warrants can amend or waive the foregoing limitation by written notice to the Company, with such waiver taking effect only upon the expiration of a 61-day notice period.

Under the terms of the 2011 Securities Purchase Agreement, on July 29, 2011, the Company filed a registration statement with the SEC to register for resale the 2011 Shares and the shares of common stock issuable upon the exercise of the Warrants (collectively, the Registrable Securities). The registration statement was declared effective on August 4, 2011. If the Company fails to keep the registration statement continuously effective for a designated time (with limited exceptions), the Company may be obligated to pay to the holders of the Registrable Securities liquidated damages in an amount equal to 1.0% per month of such holder’s pro rata interest in the total purchase price of the Private Placement, capped at a total penalty of 6.0%.

The Company received advance proceeds of approximately $20.3 million as of June 30, 2011. The remaining $3.7 million was received in July 2011 when the 2011 Private Placement closed. Total proceeds were recorded net of issuance costs of approximately $1.2 million. The 2011 Shares and Warrants were recorded as equity at their fair values on the issuance date.

2012 Private Placement

In July 2012, the Company entered into a securities purchase agreement with certain purchasers, pursuant to which the Company agreed to sell 102,000,000 shares of its common stock (2012 Shares) for an aggregate price of approximately $53.6 million, at a purchase price of $0.525 per share of common stock (2012 Private Placement). The 2012 Private Placement closed on July 30, 2012. The proceeds to the Company from the offering, net of issuance costs, were approximately $50.5 million.

In connection with entering into the securities purchase agreement, the Company also entered into a registration rights agreement. On August 24, 2012, the Company filed a registration statement with the SEC to register the 2012 Shares for resale. The registration statement was declared effective on September 6, 2012. If the Company fails to keep the registration statement continuously effective for a designated time (with limited exceptions), the Company may be obligated to pay to each holder of the 2012 Shares an amount equal to 1.5% per month of the aggregate purchase price of the unregistered 2012 Shares held by such holder, capped at a total penalty of 9.0%.

Forward-looking Statements

This Form 10-Q contains “forward-looking statements” as defined by the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties, including uncertainties associated with: the FDA’s response to our resubmitted NDA; the progress of our research, development and clinical programs; the timing of regulatory approval and commercial introduction of APF530 and future product candidates; our ability to market, commercialize and achieve market acceptance for APF530 or other future product candidates; our ability to establish collaborations for our technology, APF530 and other future product candidates; our estimates for future performance; our estimates regarding our capital requirements and our needs for additional financing; our ability to protect or enforce our intellectual property rights; volatility in the trading price of our common stock; and other risks and uncertainties identified in our filings with the Securities and Exchange Commission. We caution investors that forward-looking statements reflect our analysis only on their stated date. We do not intend to update them except as required by law.

Overview

We are a specialty pharmaceutical company developing products using our proprietary Biochronomer™ polymer-based drug delivery platform. This drug delivery platform is designed to improve the therapeutic profile of injectable pharmaceuticals by converting them from products that must be injected once or twice per day to products that need to be injected only once every one or two weeks.

The Company’s lead product candidate, APF530, is being developed for the prevention of both acute- and delayed-onset chemotherapy-induced nausea and vomiting (CINV). One of the most debilitating side effects of cancer chemotherapy, CINV is a leading cause of premature discontinuation of treatment. There is only one injectable 5-HT3 antagonist approved for the prevention of delayed-onset CINV, so this indication represents an area of particular unmet medical need. APF530 contains the 5-HT3 antagonist granisetron formulated in the Company’s proprietary Biochronomer™ drug delivery system, which allows therapeutic drug levels to be maintained for five days with a single subcutaneous injection. This five-day range is designed to cover the delayed phase of CINV, whereas currently available intravenous and oral formulations of granisetron are approved only for the prevention of acute-onset CINV. Granisetron was selected for APF530 because it is widely prescribed by physicians based on a well-established record of safety and efficacy.

In May 2009, we filed the original New Drug Application (NDA) seeking approval for APF530 with the U.S. Food and Drug Administration (FDA). The FDA issued a Complete Response Letter for APF530 in March 2010. We met with the FDA in February and March 2011 to clarify the work needed to resubmit the NDA. In September 2012, we resubmitted the NDA seeking approval for APF530 with the FDA. The FDA set a Prescription Drug User Fee Act (PDUFA) action date of March 27, 2013.

We own the worldwide rights to APF530 and are in the early stages of building the commercial infrastructure necessary to commercialize APF530 in the U.S. on our own. We are seeking corporate partners to commercialize APF530 in markets outside of the U.S.

Critical Accounting Policies and Estimates

We prepare our condensed financial statements in accordance with U.S. generally accepted accounting principles, which requires management to make estimates and assumptions. Management bases these estimates and assumptions on historical results and known trends as well as management forecasts. Actual results could differ from these estimates and assumptions. See our Annual Report on Form 10-K for the year ended December 31, 2011 (2011 10-K), Part II, Item 7 — “Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates.”

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2012, as compared to the recent accounting pronouncements described in our 2011 10-K, that we believe are of significance, or potential significance, to us.

Results of Operations for the Three and Nine Months Ended September 30, 2012 and 2011

Contract revenue, which is derived from work performed under collaborative research and development arrangements, was $0.0 million for both the three and nine months ended September 30, 2012, and $0.0 million and $0.6 million for the three and nine months ended September 30, 2011, respectively. All of our contract revenue for the nine months ended September 30, 2011 was derived from an agreement with Merial Limited (Merial) that we entered into in September 2009 for a long-acting pain management product for companion animals. In May 2011, we received notice of termination from Merial, as they did not see the commercial potential of the product under development in the animal health market.

Our research and development costs consist primarily of employee salaries and other personnel-related expenses, facility-related expenses, laboratory consumables, development manufacturing, and clinical and pre-clinical related services performed by clinical research organizations, research institutions and other outside service providers.

Research and development expenses under collaborative agreements approximate the revenue recognized, excluding milestone and up-front payments received under such arrangements.

Research and development expense for the three months ended September 30, 2012 increased by $0.7 million to $3.6 million, from $2.9 million for the three months ended September 30, 2011. Research and development expense for the nine months ended September 30, 2012 increased by $4.6 million to $10.0 million, from $5.4 million for the nine months ended September 30, 2011. Compared to the prior year periods, headcount-related costs, including stock compensation expense, and project spending for APF530 were higher in the current year periods, as we worked to address the issues raised by the FDA in the Complete Response Letter. Research and development expense for the year 2012 is expected to be higher as compared to 2011 due to project-related expenses and additional resources required for the NDA resubmission.

Our general and administrative costs consist of salaries and related expenses, professional fees, directors’ fees, investor relations costs, insurance expense and related overhead cost allocation.

General and administrative expense for the three months ended September 30, 2012 increased by $1.2 million to $2.4 million, from $1.2 million for the three months ended September 30, 2011. General and administrative expense for the nine months ended September 30, 2012 increased by $3.0 million to $5.2 million, from $2.2 million for the nine months ended September 30, 2011. The increase in the current fiscal periods was primarily due to higher stock compensation expense, consulting costs and professional fees. General and administrative expense for the year 2012 is expected to be higher as compared to 2011 due to increased support costs related to the NDA resubmission and pre-commercialization activities.

Interest expense, net was $0.2 million and $0.1 million for the three months ended September 30, 2012 and 2011, respectively. Interest expense, net was $0.4 million and $0.3 million for the nine months ended September 30, 2012 and 2011, respectively. Interest expense, net consists primarily of interest expense and amortization of debt discount related to the convertible note financing. In the prior fiscal period, interest expense also included debt issuance costs related to the convertible note financing.

Income (loss) from discontinued operations represents the income (loss) attributable to the gross profit guaranty associated with the sale of our cosmeceutical and toiletry business. The income (loss) from discontinued operations was $0.1 million and ($0.1) million for the three months ended September 30, 2012 and 2011, respectively. The income (loss) from discontinued operations was $0.0 million and ($0.3) million for the nine months ended September 30, 2012 and 2011, respectively. See Note 7 of Notes to Condensed Financial Statements included in Item 1 of this Quarterly Report on Form 10-Q for additional information.

Capital Resources and Liquidity

We had cash and cash equivalents of $60.0 million at September 30, 2012. Cash and cash equivalents increased by $42.1 million from December 31, 2011 to September 30, 2012, primarily due to net cash proceeds received from the July 2012 private placement financing and the issuance of additional convertible notes in May 2012 resulting from the exercise of purchase rights by note holders, which were partially offset by cash used in operations and equipment purchases.

Net cash used in operating activities for the nine months ended September 30, 2012 was $10.9 million, compared to net cash used in operating activities of $5.2 million for the nine months ended September 30, 2011. The $5.7 million increase in net cash used was primarily due to the increase in operating loss.

14

Net cash used in investing activities for the nine months ended September 30, 2012 was $0.5 million, compared to net cash used in investing activities of $0.1 million for the nine months ended September 30, 2011. The $0.4 million increase in net cash used was for purchases of property and equipment.

Net cash provided by financing activities for the nine months ended September 30, 2012 was $53.5 million, compared to $24.3 million in the nine months ended September 30, 2011. The increase of $29.2 million was primarily due to proceeds received from the July 2012 private placement and additional proceeds received from the issuance of convertible notes in the current fiscal year, which were partially offset by the April 2011 convertible note financing and the June 2011 private placement.

Historically, we have financed our operations, including technology and product research and development, primarily through sales of our common stock and other securities, royalties received on sales of Retin-A Micro and Carac, the sale of our rights to royalties on sales of Retin-A Micro and Carac, income from collaborative research and development fees, proceeds received from the sales of our Analytical Standards division and our cosmeceutical and toiletry business and interest earned on short-term investments.

In April 2011, we entered into definitive agreements for a convertible note financing of up to $4.5 million, which served as a bridge loan to fund the Company’s operations until additional financing was secured. The initial funding from the bridge loan was approximately $1.3 million, net of issuance costs, whereby $1.5 million aggregate principal amount of convertible notes was issued. In May 2012, the purchasers exercised their rights to purchase the remaining $3.0 million aggregate principal amount of convertible notes, and we received the additional $3.0 million of proceeds.

In June 2011, we entered into definitive agreements for a private placement of units comprised of common stock and warrants, for which we received advance proceeds of $20.3 million as of June 30, 2011. The financing closed in July 2011, at which time the remaining $3.7 million was received.

In July 2012, we closed a common stock financing whereby the Company received approximately $50.5 million of proceeds, net of issuance costs.

We believe that our current cash resources are sufficient to fund planned operations through the anticipated product launch of APF530 in 2013, assuming approval by the FDA.

Our capital requirements going forward will depend on numerous factors including: an approval decision by the FDA with respect to APF530; the timing of and cost that will be required to launch APF530, if approved; the commercial success of APF530; the number and characteristics of product development programs we pursue and the pace of each program; the scope, rate of progress, results and costs of preclinical testing and clinical trials; the time, cost and outcome involved in seeking other regulatory approvals; scientific progress in our research and development programs; the magnitude and scope of our research and development programs; our ability to establish and maintain strategic collaborations or partnerships for research, development, clinical testing, manufacturing and marketing of our product candidates; the cost and timing of establishing sales, marketing and distribution capabilities for a specialty sales force if we commercialize any products independently; the cost of establishing clinical and commercial supplies of our product candidates and any products that we may develop; and general market conditions.

We may not be able to raise sufficient additional capital when we need it or to raise capital on favorable terms. The sale of additional equity in the future may be dilutive to our stockholders. If we are unable to obtain adequate funds on reasonable terms, we may be required to curtail operations significantly or to obtain funds by entering into financing, supply or collaboration agreements on unattractive terms.

Employee Stock Purchase Plan

We adopted an Employee Stock Purchase Plan (Purchase Plan) in 1997. Qualified employees may elect to have a certain percentage of their salary withheld to purchase shares of our common stock under the Purchase Plan. In June 2011, our stockholders authorized an increase in the number of shares reserved for issuance under the Purchase Plan by 500,000, for a total of 1,000,000 shares reserved at September 30, 2012. The purchase price per share is equal to 85% of the fair market value of the stock on specified dates. Sales under the Purchase Plan during the nine months ended September 30, 2012 and 2011 consisted of 58,571 and 49,486 shares at an average price of $0.21 and $0.20, respectively.

Basic and diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the applicable period. Diluted net loss per share excludes the effect of outstanding potentially dilutive securities because they are anti-dilutive. The following table shows the outstanding potentially dilutive options, warrants and convertible notes for the nine months ended September 30, 2012 and 2011 (in thousands):

Fair Value Disclosures [Abstract]

(3) FAIR VALUE MEASUREMENTS

(3) FAIR VALUE MEASUREMENTS

The three-tier fair value hierarchy utilized prioritizes the inputs used in measuring fair value as follows: Level 1) observable inputs such as quoted prices in active markets; Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and Level 3) unobservable inputs in which there is little or no market data, which require us to develop our own assumptions. The hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, we measure our available-for-sale securities at fair value. We used quoted prices in active markets (Level l) to measure the fair value of our cash equivalents on our Condensed Balance Sheets as of September 30, 2012 and December 31, 2011. Cash equivalents consist of highly rated money market funds with maturities of ninety days or less. Due to the high ratings and short-term nature of these funds, we consider the inputs used to value all cash equivalents as Level 1 inputs.

Merial Limited

In September 2009, we entered into a world-wide license and development agreement with Merial Limited (Merial), a leading animal health company, for a long-acting pain management product for cats and dogs. Under the terms of the agreement, we received a nonrefundable upfront license fee and performed reimbursable development services. In May 2011, we received notice of termination from Merial due to their concerns about the commercial potential of the product under development in the animal health market. We recognized no revenue related to development services provided to Merial in both the three months ended September 30, 2012 and 2011, and $0.0 and $0.5 million of revenue for the nine months ended September 30, 2012 and 2011, respectively. The remaining balance of deferred revenue related to the upfront license fee of $0.1 million was recognized as revenue in the quarter ended June 30, 2011, upon termination of the licensing agreement by Merial.

Cosmeceutical and Toiletry Business

On July 25, 2000, we completed the sale of certain technology rights for our cosmeceutical and toiletry business to RP Scherer Corporation (RP Scherer), a subsidiary of Cardinal Health, Inc. Under the terms of the agreement with RP Scherer, we guaranteed a minimum gross profit percentage on RP Scherer's combined sales of products to Ortho Dermatologics (Ortho) and Dermik Laboratories, Inc. (Dermik) (Gross Profit Guaranty). In July 2011, Valeant Pharmaceuticals announced that it was acquiring both Ortho and Dermik. The guaranty period initially commenced on July 1, 2000 and was to end on the earlier of: (i) July 1, 2010; or (ii) the end of two consecutive guaranty periods where the combined gross profit on sales to Ortho and Dermik equaled or exceeded the guaranteed gross profit (Two Period Test). The Gross Profit Guaranty expense totaled $944,000 for the first seven guaranty years and in those years profits did not meet the Two Period Test. Effective March 2007, in conjunction with a sale of assets by RP Scherer's successor company to an Amcol International subsidiary (Amcol), a new agreement was signed between us and Amcol, in order to provide continuity of product supply to Ortho and Dermik. This new agreement potentially extends the Gross Profit Guaranty period an additional three years to July 1, 2013, unless it is terminated earlier with the Two Period Test. Amcol has indicated that its costs to produce the products differ from those it historically charged to the RP Scherer successor company. We have requested documentation from Amcol to substantiate actual costs. Until we receive confirmation of these amounts, we have accrued the full amount Amcol represents it is currently owed. As there is no minimum amount of Gross Profit Guaranty due, no accrual for the guaranty is estimable for future years. A liability of $1.1 million related to the current amount due under the Gross Profit Guaranty is recorded as accrued disposition costs on our Condensed Balance Sheet as of September 30, 2012. To date, we have not paid this amount, due to our inability to substantiate the amounts claimed by Amcol. As of the date of filing of this report, our dispute with Amcol over the Gross Profit Guaranty has been submitted to an independent accountant for resolution.

The cosmeceutical and toiletry business is reported as discontinued operations for all periods presented in our accompanying Condensed Statements of Operations.

Income (loss) from discontinued operations primarily represents the income (loss) attributable to changes in estimates of our cosmeceutical and toiletry business that was sold to RP Scherer on July 25, 2000, as follows (in thousands):

Accounting Policies [Abstract]

Organization and Business

A.P. Pharma, Inc. (the "Company," "we," "us" and "our") is a specialty pharmaceutical company developing products using its proprietary Biochronomer^™ polymer-based drug delivery platform. This drug delivery platform is designed to improve the therapeutic profile of injectable pharmaceuticals by converting them from products that must be injected once or twice per day to products that need to be injected only once every one or two weeks.

The Company’s lead product candidate, APF530, is being developed for the prevention of both acute- and delayed-onset chemotherapy-induced nausea and vomiting (CINV). One of the most debilitating side effects of cancer chemotherapy, CINV is a leading cause of premature discontinuation of treatment. There is only one injectable 5-HT3 antagonist approved for the prevention of delayed-onset CINV, so this indication represents an area of particular unmet medical need. APF530 contains the 5-HT3 antagonist granisetron formulated in the Company’s proprietary Biochronomer™ drug delivery system, which allows therapeutic drug levels to be maintained for five days with a single subcutaneous injection. This five-day range is designed to cover the delayed phase of CINV, whereas currently available intravenous and oral formulations of granisetron are approved only for the prevention of acute-onset CINV. Granisetron was selected for APF530 because it is widely prescribed by physicians based on a well-established record of safety and efficacy.

In May 2009, we filed the original New Drug Application (NDA) seeking approval for APF530 with the U.S. Food and Drug Administration (FDA). The FDA issued a Complete Response Letter for APF530 in March 2010. We met with the FDA in February and March 2011 to clarify the work needed to resubmit the NDA. In September 2012, we resubmitted the NDA seeking approval for APF530 with the FDA. The FDA set a Prescription Drug User Fee Act (PDUFA) action date of March 27, 2013.

We own the worldwide rights to APF530 and are in the early stages of building the commercial infrastructure necessary to commercialize APF530 in the U.S. on our own. We are seeking corporate partners to commercialize APF530 in markets outside of the U.S.

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All adjustments (all of which are of a normal recurring nature) considered necessary for a fair presentation have been included. We have evaluated subsequent events through the date that these financial statements were issued. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012 or for any other period. The condensed balance sheet as of December 31, 2011 has been derived from the audited financial statements as of that date, but it does not include all of the information and notes required by U.S. GAAP. These unaudited condensed financial statements and the notes thereto should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011, which was filed with the Securities and Exchange Commission (SEC) on March 26, 2012 (2011 10-K).

Liquidity

We have incurred significant operating losses and negative cash flows from operations and have an accumulated deficit of $175.9 million as of September 30, 2012. During 2011, we entered into two financing agreements, which provided us capital to fund operations. In April 2011, we entered into definitive agreements for a convertible note financing, which served as a bridge loan to fund the Company's operations until additional financing was secured (see Note 9). The initial cash received from the bridge loan financing was approximately $1.3 million, net of issuance costs. In June 2011, we entered into definitive agreements for a private placement of units, which comprised of common stock and warrants (see Note 10). The unit financing, which closed in July 2011, provided the Company with approximately $22.8 million of proceeds, net of issuance costs. In May 2012, we received $3.0 million of cash through the issuance of additional convertible notes as a result of the purchasers who participated in the April 2011 convertible note financing fully exercising their rights to purchase additional convertible notes. In July 2012, the Company closed a common stock financing whereby the Company received approximately $50.5 million of proceeds, net of issuance costs (see Note 10). As of September 30, 2012, we had cash and cash equivalents of $60.0 million. The Company believes that its current capital is sufficient to fund its planned operations through the anticipated product launch of APF530 in 2013, assuming FDA approval.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. We evaluate our critical accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. Our critical accounting policies and estimates are discussed in our 2011 10-K.

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2012, as compared to the recent accounting pronouncements described in our 2011 10-K, that we believe are of significance, or potential significance, to us.

Debt Disclosure [Abstract]

(9) CONVERTIBLE NOTES TO RELATED PARTIES

(9) CONVERTIBLE NOTES TO RELATED PARTIES

In April 2011, we entered into a Securities Purchase Agreement (Purchase Agreement) with certain institutional investors (Purchasers), including a fund affiliated with Kevin C. Tang, who is one of our directors, for a private placement of up to $4.5 million in Senior Secured Convertible Notes due 2021 (Notes). The Purchase Agreement provided for the Purchasers to purchase $1.5 million aggregate principal amount of Notes at the initial closing. Pursuant to the Purchase Agreement, the Purchasers had the option to purchase an additional $3.0 million aggregate principal amount of Notes at any time until May 2, 2013 (Purchase Option). The Notes are convertible into shares of the Company's common stock at a rate of 25,000 shares for every $1,000 of principal and accrued interest due under the Notes (Conversion Shares).

The cash received from the initial closing of the Note financing, which resulted in the issuance of $1.5 million aggregate principal amount of Notes, was approximately $1.3 million, net of issuance costs. In May 2012, the Purchasers exercised their Purchase Option in full, and we received $3.0 million of cash through the issuance of the remaining $3.0 million aggregate principal amount of Notes. As a result of the exercise of the Purchase Option, the Purchasers have purchased the full amount of Notes that the Company was obligated to sell under the Purchase Agreement. If the $4.5 million principal amount of Notes is converted, the Company would issue 112.5 million shares of its common stock.

The Notes are secured by substantially all of the assets of the Company, including placing our bank accounts under a control agreement. The Notes initially bore interest at 20% per annum, payable quarterly in cash or in additional principal amount of Notes at the election of the Purchasers. In June 2011, the Notes were amended to reduce the interest rate to 6% per annum effective July 1, 2011. The Notes mature on May 2, 2021; however, the holders of the Notes may require prepayment of the Notes at any time beginning on or after May 2, 2012, at each holder's option.

There is no right to convert the Notes to the extent that, after giving effect to such conversion, the holder would beneficially own in excess of 9.99% of the Company's outstanding common stock. Each holder of the Notes can increase or decrease this beneficial ownership conversion limit by written notice to the Company, which will not be effective until 61 days after delivery of the notice.

As of September 30, 2012, the Company was in compliance with all debt-related covenants under the Notes. Upon the occurrence of an event of default under the Notes, the holders of the Notes have the right to require the Company to redeem all or a portion of their Notes.

Pursuant to the Purchase Agreement, the Company filed a registration statement on Form S-1 registering for resale 69.6 million shares underlying the Notes. The registration statement was declared effective on July 29, 2011. The Purchasers have agreed to waive their right to require the Company to register the additional shares underlying the Notes until they provide notice otherwise.

Concurrent with the approval of the offer and sale of the Notes, our board of directors approved the termination of the Company's Preferred Shares Rights Agreement (Rights Agreement), effective immediately prior to the Purchase Agreement’s initial closing date.

The Notes contain an embedded conversion feature that was in-the-money on both issuance dates. Based on an effective fixed conversion rate of 25,000 shares for every $1,000 of principal and accrued interest due under the Notes, the total conversion benefit at issuance exceeded the loan proceeds. Therefore, a full debt discount was recorded in an amount equal to the face value of the Notes on the issuance dates, and the Company began amortizing the resultant debt discount over the respective 10-year or remaining term of the Notes. During the three and nine months ended September 30, 2012, accrued interest of approximately $51,000 and $98,000 was paid-in-kind and rolled into the principal balance of the Notes, which resulted in an additional full debt discount for the respective periods. For the three and nine months ended September 30, 2012, interest expense relating to the stated rate of the Notes was approximately $70,000 and $145,000, respectively. Interest expense relating to the amortization of debt discount for the three and nine months ended September 30, 2012 was approximately $125,000 and $262,000, respectively.

As of September 30, 2012, the carrying value of the Notes was approximately $365,000, which is comprised of the $4,672,000 principal amount of the Notes outstanding, less debt discount of $4,307,000. Accrued interest on the principal balance was $70,000 at September 30, 2012.

Amendments to Articles of Incorporation

In June 2011, we amended our certificate of incorporation to increase the number of shares of authorized common stock to 1,500,000,000, par value $0.01 per share. Prior to the amendment, the number of shares of authorized common stock was 100,000,000, par value $0.01 per share. The certificate of amendment was approved by a majority of our stockholders on June 29, 2011.

Stock Plans

At our annual meeting of stockholders in June 2011, our stockholders approved an amendment to our 2007 Equity Incentive Plan to increase the maximum number of shares of common stock available for grant by 90,000,000 shares of common stock, resulting in an aggregate of 95,000,000 shares of common stock authorized for issuance pursuant to awards granted under our 2007 Equity Incentive Plan. The stockholders also approved an amendment to our 1997 Employee Stock Purchase Plan to increase the number of shares of common stock reserved for issuance under the plan by 500,000, for a total of 1,000,000 shares reserved as of September 30, 2012.

2011 Private Placement

In June 2011, the Company entered into a securities purchase agreement with certain purchasers (2011 Securities Purchase Agreement), pursuant to which the Company agreed to sell for an aggregate price of $24.0 million, 160,000,006 shares of its common stock (2011 Shares) and warrants to purchase 80,000,005 shares of its common stock (Warrants) at an exercise price of $0.18 per share (2011 Private Placement). The 2011 Private Placement closed on July 1, 2011. For each share purchased, the investors received one Warrant to purchase 0.5 shares of common stock (together with a share, a Unit), at a purchase price of $0.15 per Unit. The Warrants were immediately exercisable and expire on the fifth anniversary of the closing date of July 1, 2011. The Warrants may be exercised for cash only or, if a registration statement is not then effective and available for the resale of the shares of common stock issuable upon exercise of the Warrants, by surrender of such Warrant, or a portion of such Warrant, by way of cashless exercise. There is no right to exercise the Warrants to the extent that after giving effect to such exercise the holder would beneficially own in excess of 9.99% of our outstanding shares of common stock (or such other limit as may be designated by any particular purchaser). Each holder of the Warrants can amend or waive the foregoing limitation by written notice to the Company, with such waiver taking effect only upon the expiration of a 61-day notice period.

Under the terms of the 2011 Securities Purchase Agreement, on July 29, 2011, the Company filed a registration statement with the SEC to register for resale the 2011 Shares and the shares of common stock issuable upon the exercise of the Warrants (collectively, the Registrable Securities). The registration statement was declared effective on August 4, 2011. If the Company fails to keep the registration statement continuously effective for a designated time (with limited exceptions), the Company may be obligated to pay to the holders of the Registrable Securities liquidated damages in an amount equal to 1.0% per month of such holder's pro rata interest in the total purchase price of the Private Placement, capped at a total penalty of 6.0%.

The Company received advance proceeds of approximately $20.3 million as of June 30, 2011. The remaining $3.7 million was received in July 2011 when the 2011 Private Placement closed. Total proceeds were recorded net of issuance costs of approximately $1.2 million. The 2011 Shares and Warrants were recorded as equity at their fair values on the issuance date.

2012 Private Placement

In July 2012, the Company entered into a securities purchase agreement with certain purchasers, pursuant to which the Company agreed to sell 102,000,000 shares of its common stock (2012 Shares) for an aggregate price of approximately $53.6 million, at a purchase price of $0.525 per share of common stock (2012 Private Placement). The 2012 Private Placement closed on July 30, 2012. The proceeds to the Company from the offering, net of issuance costs, were approximately $50.5 million.

In connection with entering into the securities purchase agreement, the Company also entered into a registration rights agreement. On August 24, 2012, the Company filed a registration statement with the SEC to register the 2012 Shares for resale. The registration statement was declared effective on September 6, 2012. If the Company fails to keep the registration statement continuously effective for a designated time (with limited exceptions), the Company may be obligated to pay to each holder of the 2012 Shares an amount equal to 1.5% per month of the aggregate purchase price of the unregistered 2012 Shares held by such holder, capped at a total penalty of 9.0%.

(1) BUSINESS AND BASIS OF PRESENTATION

A.P. Pharma, Inc. (the "Company," "we," "us" and "our") is a specialty pharmaceutical company developing products using its proprietary Biochronomer^™ polymer-based drug delivery platform. This drug delivery platform is designed to improve the therapeutic profile of injectable pharmaceuticals by converting them from products that must be injected once or twice per day to products that need to be injected only once every one or two weeks.

The Company’s lead product candidate, APF530, is being developed for the prevention of both acute- and delayed-onset chemotherapy-induced nausea and vomiting (CINV). One of the most debilitating side effects of cancer chemotherapy, CINV is a leading cause of premature discontinuation of treatment. There is only one injectable 5-HT3 antagonist approved for the prevention of delayed-onset CINV, so this indication represents an area of particular unmet medical need. APF530 contains the 5-HT3 antagonist granisetron formulated in the Company’s proprietary Biochronomer™ drug delivery system, which allows therapeutic drug levels to be maintained for five days with a single subcutaneous injection. This five-day range is designed to cover the delayed phase of CINV, whereas currently available intravenous and oral formulations of granisetron are approved only for the prevention of acute-onset CINV. Granisetron was selected for APF530 because it is widely prescribed by physicians based on a well-established record of safety and efficacy.

In May 2009, we filed the original New Drug Application (NDA) seeking approval for APF530 with the U.S. Food and Drug Administration (FDA). The FDA issued a Complete Response Letter for APF530 in March 2010. We met with the FDA in February and March 2011 to clarify the work needed to resubmit the NDA. In September 2012, we resubmitted the NDA seeking approval for APF530 with the FDA. The FDA set a Prescription Drug User Fee Act (PDUFA) action date of March 27, 2013.

We own the worldwide rights to APF530 and are in the early stages of building the commercial infrastructure necessary to commercialize APF530 in the U.S. on our own. We are seeking corporate partners to commercialize APF530 in markets outside of the U.S.

The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All adjustments (all of which are of a normal recurring nature) considered necessary for a fair presentation have been included. We have evaluated subsequent events through the date that these financial statements were issued. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012 or for any other period. The condensed balance sheet as of December 31, 2011 has been derived from the audited financial statements as of that date, but it does not include all of the information and notes required by U.S. GAAP. These unaudited condensed financial statements and the notes thereto should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011, which was filed with the Securities and Exchange Commission (SEC) on March 26, 2012 (2011 10-K).

Liquidity

We have incurred significant operating losses and negative cash flows from operations and have an accumulated deficit of $175.9 million as of September 30, 2012. During 2011, we entered into two financing agreements, which provided us capital to fund operations. In April 2011, we entered into definitive agreements for a convertible note financing, which served as a bridge loan to fund the Company's operations until additional financing was secured (see Note 9). The initial cash received from the bridge loan financing was approximately $1.3 million, net of issuance costs. In June 2011, we entered into definitive agreements for a private placement of units, which comprised of common stock and warrants (see Note 10). The unit financing, which closed in July 2011, provided the Company with approximately $22.8 million of proceeds, net of issuance costs. In May 2012, we received $3.0 million of cash through the issuance of additional convertible notes as a result of the purchasers who participated in the April 2011 convertible note financing fully exercising their rights to purchase additional convertible notes. In July 2012, the Company closed a common stock financing whereby the Company received approximately $50.5 million of proceeds, net of issuance costs (see Note 10). As of September 30, 2012, we had cash and cash equivalents of $60.0 million. The Company believes that its current capital is sufficient to fund its planned operations through the anticipated product launch of APF530 in 2013, assuming FDA approval.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. We evaluate our critical accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. Our critical accounting policies and estimates are discussed in our 2011 10-K.

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2012, as compared to the recent accounting pronouncements described in our 2011 10-K, that we believe are of significance, or potential significance, to us.
