CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1—DESCRIPTION OF BUSINESS

Pacira Pharmaceuticals, Inc. and its subsidiaries (collectively, the “Company” or “Pacira”) is an emerging specialty pharmaceutical company focused on the development, commercialization and manufacture of proprietary pharmaceutical products, based on its proprietary DepoFoam extended release drug delivery technology, for use in hospitals and ambulatory surgery centers. The Company’s lead product candidate EXPAREL consists of bupivacaine encapsulated in DepoFoam, both of which are used in products approved by the United States Food and Drug Administration, or FDA. In September 2010, the Company filed a New Drug Application, or NDA, for EXPAREL with the FDA. Under the Prescription Drug User Fee Act, or PDUFA, guidelines, the FDA has a goal of ten months from the date of NDA filing to make a decision regarding the approval of our filing. The FDA subsequently extended the target date by three months. The new PDUFA goal date for our NDA is October 28, 2011. The Company is initially seeking FDA approval for postsurgical analgesia by local administration into the surgical site. DepoFoam is also the basis for the Company’s two FDA-approved commercial products, DepoCyt(e) and DepoDur, which the Company manufactures for its commercial partners.

Note 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and in accordance with the rules and regulations of the Securities and Exchange Commission, or SEC, for interim reporting. Pursuant to these rules and regulations, certain information and footnote disclosures normally included in complete annual financial statements have been condensed or omitted. Therefore, these interim financial statements should be read in conjunction with the audited annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, filed with the SEC on March 31, 2011.

The consolidated financial information at June 30, 2011 and for the three and six months ended June 30, 2011 and 2010, is unaudited, but includes all adjustments (consisting of only normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the financial information set forth herein in accordance with GAAP. The balance sheet as of December 31, 2010 has been derived from the audited financial statements included in the Form 10-K for that year. Certain reclassifications were made to conform to current presentation. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

The results of operations for the interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. The Company has incurred losses and negative operating cash flow since inception and future losses are anticipated. As further described in Note 8, the Company raised $42.0 million of gross proceeds, and approximately $37.1 million in net proceeds after deducting offering costs, through an initial public offering completed on February 8, 2011. Although net proceeds from the offering and its other cash resources provide the Company adequate funding for the next 12 months, the longer-term ability of the Company to continue as a going concern is dependent on improving the Company’s profitability, cash flow and securing additional financing.

Recently Issued Accounting Guidance

In June 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2011-05, “Presentation of Comprehensive Income.” These changes give an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. ASU No. 2011-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 (January 1, 2012 for the Company) and interim and annual periods thereafter. Early adoption is permitted, and full retrospective application is required. Since this ASU pertains to presentation requirements only, the adoption of this ASU will not have a material impact on the Company’s consolidated financial statements.

Changes in Capital Structure

On January 12, 2011, the Company effected a one-for-10.755 reverse stock split of the Company’s outstanding common stock. Stockholders entitled to fractional shares as a result of the reverse stock split will receive a cash payment for such fractional shares in lieu of receiving fractional shares. The reverse stock split affected all holders of the Company’s preferred stock and common stock uniformly. All references to common stock and per share information, except par value, in the accompanying consolidated financial statements and notes thereto have been adjusted retrospectively to reflect the effect of the reverse stock split.

On February 8, 2011, the Company completed an initial public offering of common stock, as further described in Note 8. Upon the closing of the initial public offering, all outstanding shares of Series A convertible preferred stock and the principal and accrued interest balance on the 2009 Convertible Notes, 2009 Secured Notes, 2010 Secured Notes, 2010 Convertible Notes, and HBM Secured Notes were converted into 10,658,845 shares of common stock. On February 8, 2011, the Company filed an Amended and Restated Certificate of Incorporation (“Amended Certificate of Incorporation”), whereby the Company (i) increased its authorized common stock from 120,000,000 shares ($0.001 par value) to 250,000,000 shares ($0.001 par value), (ii) authorized 5,000,000 shares ($0.001 par value) of preferred stock, and (iii) eliminated the previously existing series of preferred stock.

Concentration of Major Customers

The Company’s customers are its commercial, distribution and licensing partners. For the three months ended June 30, 2011, the Company’s three largest customers accounted for 45%, 21% and 18%, respectively, of the Company’s revenues. For the three months ended June 30, 2010, the Company’s four largest customers accounted for 35%, 34%, 13% and 11%, respectively, of the Company’s revenues.

For the six months ended June 30, 2011, the Company’s three largest customers accounted for 43%, 22% and 19%, respectively, of the Company’s revenues. For the six months ended June 30, 2010, the Company’s four largest customers accounted for 48%, 23%, 13% and 12%, respectively, of the Company’s revenues. No other individual customer accounted for more than 10% of revenues for these periods. The Company is dependent on these commercial partners to market and sell DepoCyt(e) and DepoDur, from which a substantial portion of its revenues is derived. Therefore, the Company’s future revenues from these products are highly dependent on commercial and distribution arrangements.

Domestic revenues for the three months ended June 30, 2011 and 2010 accounted for 32% and 63% of the Company’s revenues, respectively. Domestic revenues for the six months ended June 30, 2011 and 2010 accounted for 36% and 50% of the Company’s revenues, respectively.

Per Share Data

Net loss per share was determined in accordance with the two-class method. This method is used for computing basic net loss per share when companies have issued securities other than common stock that contractually entitle the holder to participate in dividends and earnings of the Company. Under the two-class method, net loss is allocated between common shares and other participating securities based on their participation rights in both distributed and undistributed earnings. The Company’s Series A convertible preferred stock is a participating security, because the stockholders of the Series A Convertible preferred stock are entitled to share in dividends declared by the board of directors with the common stock based on their equivalent common shares.

Basic net loss per share is computed by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Because the holders of the Series A Convertible Preferred Stock are not contractually required to share in the Company’s losses, in applying the two-class method to compute basic net loss per common share no allocation to preferred stock was made.

Diluted net loss per share is calculated by dividing net loss available (attributable) to common stockholders as adjusted for the effect of dilutive securities, if any, by the weighted average number of common stock and dilutive common stock outstanding during the period. Potential common shares include the shares of common stock issuable upon the exercise of outstanding stock options and warrants (using the treasury stock method) and the conversion of the shares of Series A convertible preferred stock (using the more dilutive of the (a) as converted method or (b) the two-class method). Potential common shares in the diluted net loss per share computation are excluded to the extent that they would be anti-dilutive. No potentially dilutive securities are included in the computation of any diluted per share amounts as the Company reported a net loss for all periods presented. Potentially dilutive securities that would be issued upon the conversion of convertible notes, conversion of Series A convertible preferred stock and the exercise of outstanding warrants and stock options, were 1.3 million and 7.2 million for the three months ended June 30, 2011 and 2010, respectively. Potentially dilutive securities that would be issued upon the conversion of convertible notes, conversion of Series A convertible preferred stock and the exercise of outstanding warrants and stock options, were 1.4 million and 7.2 million for the six months ended June 30, 2011 and 2010, respectively.

Note 3— FINANCIAL INSTRUMENTS

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction. To increase consistency and comparability in fair value measurements, the FASB established a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels are:

•

Level 1—Values are unadjusted quoted prices for identical assets and liabilities in active markets.

•

Level 2—Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices from those willing to trade in markets that are not active, or other inputs that are observable or can be corroborated by market data for the term of the instrument.

•

Level 3—Certain inputs are unobservable (supported by little or no market activity) and significant to the fair value measurement.

The carrying value of financial instruments including cash and cash equivalents, restricted cash, accounts receivable, note receivable, and accounts payable approximate their respective fair values due to the short-term maturities of these instruments and debts. The carrying value of the long-term debt approximates its fair value since the interest rate approximates current market rate for similar instruments.

Short-term investments consist of investment grade commercial paper and corporate bonds with initial maturities of greater than three months at the date of purchase but less than one year. The net unrealized loss from the Company’s short-term investments is captured in other comprehensive income. At June 30, 2011, all of the Company’s short-term investments are classified as available for sale investments and determined to be Level 2 instruments, which are measured at fair value using standard industry models with observable inputs. At June 30, 2011, we had $19.8 million invested in short-term investments which were rated A or better by Standard & Poor’s and had maturities ranging from 98 to 158 days. The following summarizes the Company’s short-term investments at June 30, 2011 (in thousands):


	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value (Level 2)
Debt securities:
Commercial Paper	$	10,491	$	8	$	—		$	10,499
Corporate Bonds		9,264		—		(8	)		9,256

Total	$	19,755	$	8	$	(8	)	$	19,755

Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments and accounts receivable. The Company maintains its cash and cash equivalents with high-credit quality financial institutions. At times, such amounts may exceed Federal insured limits.

As of June 30, 2011, the Company’s two largest customers accounted for 71% and 27%, respectively, of the Company’s trade accounts receivable. As of December 31, 2010, the Company’s three largest customers accounted for 66%, 17% and 11%, respectively, of the Company’s trade accounts receivable.

Overview

We are an emerging specialty pharmaceutical company focused on the development, commercialization and manufacture of proprietary pharmaceutical products, based on our proprietary DepoFoam drug delivery technology, for use in hospitals and ambulatory surgery centers. In September 2010, we filed a New Drug Application, or NDA, for EXPAREL with the United States Food and Drug Administration, or FDA, which was accepted by the FDA for review on December 10, 2010, using a 505(b)(2) application. Our clinical data demonstrates that EXPAREL provides analgesia for up to 72 hours post-surgery. The published duration of bupivacaine analgesia (package insert) is 7 hours. We are initially seeking approval for postsurgical analgesia by local administration into the surgical site, or infiltration, a procedure commonly employed using bupivacaine. Under the Prescription Drug User Fee Act, or PDUFA, guidelines, the FDA has a goal of ten months from the date of NDA filing to make a decision regarding the approval of our filing. The FDA subsequently extended the target date by three months. The new PDUFA goal date for our NDA is October 28, 2011. We are also pursuing several additional indications for EXPAREL and we currently expect to submit a supplemental NDA, or sNDA, for nerve block and other administrations. We currently intend to develop and commercialize EXPAREL and our other product candidates in the United States while out-licensing commercialization rights for other territories.

Our two marketed products, DepoCyt(e) and DepoDur, and our proprietary DepoFoam extended release drug delivery technology were acquired as part of the acquisition of PPI-California on March 24, 2007, or the Acquisition. DepoCyt(e) is a sustained release liposomal formulation of the chemotherapeutic agent cytarabine and is indicated for the intrathecal treatment of lymphomatous meningitis. DepoCyt(e) was granted accelerated approval by the FDA in 1999 and full approval in 2007. DepoDur is an extended release injectable formulation of morphine indicated for epidural administration for the treatment of pain following major surgery. DepoDur was approved by the FDA in 2004.

Since inception, we have incurred significant operating losses. Our net loss was $18.5 million for the six months ended June 30, 2011, including research and development expenses of $7.9 million. We do not expect our currently marketed products to generate revenue that is sufficient for us to achieve profitability because we expect to continue to incur significant expenses as we advance the development of EXPAREL and our other product candidates, seek FDA approval for our product candidates that successfully complete clinical trials and develop our sales force and marketing capabilities to prepare for their

commercial launch. We also expect to incur additional expenses to add operational, financial and management information systems and personnel, including personnel to support our product development efforts and our obligations as a public reporting company. For us to become and remain profitable, we believe that we must succeed in commercializing EXPAREL or other product candidates with significant market potential.

Recent Developments

Initial Public Offering

On February 8, 2011, we completed our initial public offering of our common stock pursuant to a registration statement on Form S-1, as amended (File No. 333-170245) that was declared effective on February 2, 2011. An aggregate of 6,000,000 shares of common stock registered under the registration statement were sold at a price to the public of $7.00 per share. The over-allotment option was not exercised by the underwriters. As a result of our initial public offering, we raised a total of $42.0 million in gross proceeds, and approximately $37.1 million in net proceeds after deducting underwriting discounts and commissions and other offering expenses. Upon the closing of the initial public offering, all shares of outstanding Series A convertible preferred stock and the principal and accrued interest balance on the 2009 Convertible Notes, 2009 Secured Notes, 2010 Secured Notes, 2010 Convertible Notes, and HBM Secured Notes were converted into an aggregate of 10,658,845 shares of common stock.

Novo Nordisk Development and License Agreement

In January 2011, we entered into an agreement with Novo Nordisk A/S, or Novo, pursuant to which we granted non-exclusive rights to Novo under certain of our patents and know-how to develop, manufacture and commercialize formulations of a Novo proprietary drug using our DepoFoam drug delivery technology. Under this agreement, we agreed to undertake specified development and technology transfer activities and to manufacture pre-clinical and certain clinical supplies of such DepoFoam formulated Novo product until the completion of such technology transfer activities. Novo is obligated to pay for all costs we incur in conducting such development, manufacturing and technology transfer activities. We received an upfront license fee of $1.5 million from Novo, which is being recognized on a straight-line basis over the estimated contract term. We are also entitled to receive single-digit royalties on sales of such Novo product for up to twelve years following the first commercial sale of such Novo product. In addition, we are entitled to receive up to $24 million in milestone payments based on achievement of specified development events, and up to an additional $20 million in milestone payments based on sales of such Novo product exceeding specified amounts. The term of this agreement shall expire, on a country-by-country basis, upon the later of the date of expiration of all payment obligations under the agreement or twelve years following the first commercial sale of such Novo product. The agreement is subject to earlier termination under certain circumstances.

Financial Operations Overview

Revenues

Our revenue that is derived from DepoCyt(e) and DepoDur is comprised of two components: supply revenue and royalties. We manufacture these products, which are then sold to our commercial partners. Supply revenue is derived from a contractual supply price paid to us by our commercial partners. Royalties are recognized as the product is sold by our commercial partners and is typically calculated as a percentage of the net selling price, which is net of discounts, returns, and allowances incurred by our commercial partners. Accordingly, the primary factors that determine our revenues derived from DepoCyt(e) and DepoDur are:

•

the level of orders submitted by our commercial partners;

•

the timing of running manufacturing lots sold to our commercial partners;

•

the level of prescription and institutional demand for our products;

•

unit sales prices;

•

the amount of gross-to-net sales adjustments realized by our commercial partners; and

•

exchange rates on European sales, denominated in euros, that are repatriated in dollars.

We also generate collaborative licensing and development revenue from our collaborations with third parties who seek to use our DepoFoam technology to develop extended release formulations of their products and product candidates.

Cost of Revenues

Cost of revenues consists of the costs associated with producing our products for our commercial partners and providing research and development services to our collaboration partners. In particular, our cost of revenues includes:

•

manufacturing overhead and fixed costs associated with running two cGMP manufacturing facilities, including salaries and related costs of personnel involved with our manufacturing activities;

•

allocated overhead, personnel conducting research and development, as well as research and development performed by outside contractors or consultants for our collaborative licensing and development activities;

•

royalties due to third parties on our revenues;

•

packaging, testing, freight and shipping;

•

the cost of active pharmaceutical ingredients; and

•

overhead costs associated with excess manufacturing capacity, which are charged to cost of revenues as incurred.

Research and Development Expenses

Our research and development expenses consist of expenses incurred in developing, testing, manufacturing and seeking regulatory approval of our product candidates, including:

•

expenses associated with regulatory submissions, clinical trials and manufacturing, including additional expenses to prepare for the commercial manufacture of EXPAREL, such as the hiring and training of additional personnel;

•

payments to third-party contract research organizations, contract laboratories and independent contractors;

•

payments made to consultants who perform research and development on our behalf and assist us in the preparation of regulatory filings;

•

payments made to third-party investigators who perform research and development on our behalf and clinical sites where such research and development is conducted;

•

personnel related expenses, such as salaries, benefits, travel and other related expenses, including stock-based compensation; and

•

facility, maintenance, and allocated rent, utilities, and depreciation and amortization, and other related expenses.

Clinical trial expenses and manufacturing process development for our product candidates are a significant component of our current research and development expenses. Product candidates in later stage clinical development, such as EXPAREL, generally have higher research and development expenses than those in earlier stages of development, primarily due to the increased size and duration of the clinical trials and manufacturing process development. We coordinate clinical trials through a number of contracted investigational sites and recognize the associated expense based on a number of factors, including actual and estimated subject enrollment and visits, direct pass-through costs and other clinical site fees.

From the Acquisition date through June 30, 2011, we incurred research and development expenses of $106.6 million, of which $102.9 million is related to the development of EXPAREL. We incurred research and development expenses associated with the development of EXPAREL of $7.8 million for the six months ended June 30, 2011 and $8.8 million for the six months ended June 30, 2010.

We expect to incur additional research and development expenses as we develop EXPAREL in additional indications. These expenditures are subject to numerous uncertainties regarding timing and cost to completion. Completion of clinical trials may take several years or more and the length of time generally varies according to the type, complexity, novelty and intended use of a product candidate. We are currently unable to determine our future research and development expenses related to EXPAREL because the timing and outcome of the FDA’s review of the NDA for EXPAREL is not currently known and the requirements of any additional clinical trials of EXPAREL for additional indications has yet to be determined. The cost of clinical development may vary significantly due to factors such as the scope, rate of progress, expense and outcome of our clinical trials and other development activities.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation, for personnel serving in our executive, finance, accounting, legal, human resource, and sales and marketing functions. Our selling, general and administrative expenses also include facility and related costs not included in research and development expenses and cost of revenues, professional fees for legal, consulting, tax and accounting services, insurance, depreciation and general corporate expenses. We expect that our selling, general and administrative expenses will

increase with the continued development and potential commercialization of our product candidates and increased expenses associated with us becoming a public company. Additionally, we are building a commercial infrastructure for the anticipated launch of EXPAREL and we currently plan to hire most of our sales force only if EXPAREL is approved by the FDA.

Other (Expense) Income

Other (expense) income consists of interest income, interest expense, and royalty interest obligation. Interest income consists of interest earned on our cash and cash equivalents, and amortization of discount on a note receivable from one of our commercial partners. Interest expense consists primarily of cash and non-cash interest costs related to our credit facility, our secured and unsecured notes issued to certain of our investors that converted into common stock upon completion of our initial public offering, and negotiated rent deferral payments. Royalty interest obligation consists of our royalty payments made in connection with the amended and restated royalty interests assignment agreement, or the Amended and Restated Royalty Interests Assignment Agreement, with Royalty Securitization Trust I, an affiliate of Paul Capital Advisors, LLC, or Paul Capital.

We record our royalty interest obligation as a liability in our consolidated balance sheets in accordance with ASC 470-10-25, Sales of Future Revenues. We impute interest expense associated with this liability using the effective interest rate method. The effective interest rate may vary during the term of the agreement depending on a number of factors including the actual sales of DepoCyt(e) and DepoDur and a significant estimation, performed quarterly, of certain of our future cash flows related to these products during the remaining term of the Amended and Restated Royalty Interests Assignment Agreement which terminates on December 31, 2014. The effect of the change in the estimates is reflected in our consolidated statements of operations as royalty interest obligation within other (expense) income. In addition, such cash flows are subject to foreign exchange movements related to sales of DepoCyt(e) and DepoDur denominated in currencies other than U.S. dollars.

Results of Operations

Comparison of Three and Six Months Ended June 30, 2011 and 2010

The following table sets forth a summary of our supply revenue, royalties and collaborative licensing and development revenue during the periods indicated:

(1)	Total DepoCyt(e) and DepoDur revenue does not include collaborative licensing and development revenue related to

DepoCyt(e) and DepoDur.

Revenues increased by $0.6 million, or 19%, in the three months ended June 30, 2011 as compared to the three months ended June 30, 2010 primarily due to an increase of $0.5 million in collaborative licensing and development revenue and $0.1 million increase in royalties while supply revenue remained constant. The increase in collaborative licensing and development revenue is primarily attributable to activities performed under the agreement with Novo signed in January 2011.

Revenues decreased by $0.3 million, or 4%, in the six months ended June 30, 2011 as compared to the six months ended June 30, 2010 primarily due to a decrease in supply revenue of $1.2 million, partially offset by $0.7 million increase in collaborative licensing and development revenue. The decrease in supply revenue was driven by lower number of lot sales of DepoCyt(e) and DepoDur and reflects the variable nature of product orders from the Company’s commercial partners and our practice of running periodic manufacturing campaigns of several lots at a time to increase manufacturing efficiency, which results in supply revenue not falling uniformly within quarters. The increase in collaborative licensing and development revenue is primarily attributable to the agreement with Novo signed in January 2011.

Total cost of revenues	$	3,115	$	2,849		9	%	$	6,781	$	6,595		3	%

Cost of revenues increased $0.3 million, or 9%, for the three months ended June 30, 2011 as compared to the three months ended June 30, 2010. The increase is primarily driven by higher maintenance costs related to our manufacturing sites and higher compensation costs including wage increases, bonuses and employer matches, which had not been provided for in 2010. We have excess capacity and we incur a minimum level of infrastructure cost to keep our manufacturing facilities cGMP compliant. The cost of excess capacity was $1.9 million and $1.3 million for the three months ended June 30, 2011 and 2010, respectively.

Cost of revenues increased $0.2 million, or 3%, for the six months ended June 30, 2011 as compared to the six months ended June 30, 2010. Cost of supplies was higher in 2011 due to higher maintenance costs and compensation costs as discussed above, including $0.1 million of increased stock-based compensation expense. The impact of fewer lots sold in 2011 versus 2010 was not material because the production cost associated with our existing products DepoDur and DepoCyt(e) is mostly fixed. The cost of excess capacity was $4.1 million and $2.9 million for the six months ended June 30, 2011 and 2010, respectively.

Research and development	$	4,381	$	4,596		-5	%	$	7,893	$	9,238		-15	%

Research and development expenses decreased by $0.2 million, or 5%, in the three months ended June 30, 2011 as compared to the three months ended June 30, 2010 primarily due to lower clinical trial costs related to the close out of our pivotal Phase 3 placebo controlled studies in EXPAREL and NDA preparation costs partially offset by an increase in EXPAREL manufacturing-related costs as well as higher compensation costs, as discussed in the previous section. In the three months ended June 30, 2011 and 2010, research and development expenses attributable to EXPAREL were $4.3 million, or 99%, and $4.2 million, or 91%, of total research and development expenses, respectively.

Research and development expenses decreased by $1.3 million, or 15%, in the six months ended June 30, 2011 as compared to the six months ended June 30, 2010 primarily due to $2.0 million decrease in third party clinical trials costs, to $0.9 million in 2011 from $2.9 million in 2010. This decrease, as mentioned above, is related to lower clinical trial costs related to the close out of our pivotal Phase 3 placebo controlled studies in EXPAREL and NDA preparation costs and was partially offset by $0.4 million in higher process development costs for EXPAREL. In the six months ended June 30, 2011 and 2010, research and development expenses attributable to EXPAREL were $7.8 million, or 99%, and $8.8 million, or 95% of total research and development expenses, respectively. The EXPAREL expenses incurred during the three and six months ended June 30, 2011 primarily include manufacturing-related costs that we expensed prior to regulatory approval of the product. The remaining research and development expenses relate to our other product candidate initiatives including DepoNSAID and DepoMethotrexate.

Selling, general and administrative expenses increased by $3.4 million, or 277%, in the three months ended June 30, 2011 as compared to the three months ended June 30, 2010 due to the following:

•

Selling expenses increased by $2.3 million from $0.1 million at June 30, 2010 to $2.4 million at June 30, 2011 primarily due to the hiring of commercial personnel and activities in anticipation of the commercial launch of EXPAREL; and

•

General and administrative expenses increased by $1.1 million from $1.1 million at June 30, 2010 to $2.2 million at June 30, 2011 due to increased stock-based compensation expense, hiring of additional personnel and expenses associated with being a public company.

Selling, general and administrative expenses increased by $6.2 million, or 276%, in the six months ended June 30, 2011 as compared to the six months ended June 30, 2010 due to the following:

•

$3.5 million increase in selling expenses from $0.2 million for the six months ended June 30, 2010 to $3.7 million for the six months ended June 30, 2011 due to the hiring of commercial personnel and activities in anticipation of the commercial launch of EXPAREL as mentioned above; and

•

$2.7 million increase in general and administrative expenses from $2.1 million for the six months ended June 30, 2010 to $4.8 million for the six months ended June 30, 2011 primarily due to (i) $1.1 million of stock-based compensation expense recognized in connection with certain stock options becoming exercisable upon the completion of our initial public offering in February 2011, (ii) hiring of additional personnel and (iii) certain expenses associated with public company operations.

Total other (expense) income, net decreased by $1.0 million, or 80%, in the three months ended June 30, 2011 as compared to the three months ended June 30, 2010 primarily due to $0.9 million decrease in the royalty interest obligation due to changes in forecasted sales projections based on recent lower trends. This obligation is due under an agreement, further discussed below in Liquidity and Capital Resources, which provides Paul Capital a right to receive an interest in our product sales relating to Depocyt(e) and DepoDur.

Total other (expense) income, net increased by $0.9 million, or 47%, in the six months ended June 30, 2011 as compared to the six months ended June 30, 2010 primarily due to:

•

$1.7 million increase in interest expense due to (i) $1.5 of million interest expense on the Hercules Note which was established in November 2010, (ii) $1.1 million amortization of the remaining value of the warrants and beneficial conversion feature associated with our 2010 Convertible Notes due to the conversion of the notes into common stock upon closing of our initial public offering in February 2011, partially offset by a $0.8 million decrease in interest expense on secured and convertible notes due to the conversion into common stock; and

•

$0.7 million decrease in the royalty interest obligation due to changes in forecasted sales projections based on recent lower trends.

Liquidity and Capital Resources

Since our inception in 2007, we have devoted most of our cash resources to research and development and general and administrative activities primarily related to the development of EXPAREL. We have financed our operations primarily with the proceeds of the sale of convertible preferred stock, secured and unsecured notes and borrowings under debt facilities,

supply revenue, royalties and collaborative licensing and development revenue. We raised $42.0 million of gross proceeds, and approximately $37.1 million in net proceeds through an initial public offering completed on February 8, 2011. We have generated limited supply revenue and royalties, and we do not anticipate generating any revenues from the sale of EXPAREL, if approved, until at least the fourth quarter of 2011. We have incurred losses and generated negative cash flows from operations since inception. As of June 30, 2011, we had an accumulated deficit of $155.4 million, cash and cash equivalents and short-term investments of $47.2 million and working capital of $36.1 million.

Summary of Cash Flows

The following table summarizes our cash flows from operating, investing and financing activities for the periods indicated:


	Six Months Ended
(000’s)	June 30,
Consolidated Statement of Cash Flows Data:	2011			2010
Net cash provided by (used in):
Operating activities	$	(14,910	)	$	(12,127	)
Investing activities		(21,790	)		(1,923	)
Financing activities		38,017			19,326

Net increase in cash and cash equivalents	$	1,317		$	5,276

Operating Activities

During the six months ended June 30, 2011 and 2010, our net cash used in operating activities was $14.9 million and $12.1 million, respectively. The increase in net cash used in operating activities was driven by (i) $1.2 million lower supply sales due to the timing of orders from our commercial partners, (ii) $1.2 million increase in interest paid primarily due to higher debt balances outstanding in 2011 and (iii) higher selling, general and administrative expenses as we prepare for the commercial launch of EXPAREL. This was partially offset by a $1.5 million up-front payment received from our development partner Novo Nordisk and lower research and development expenses due to the closeout of our two pivotal phase 3 clinical trials in EXPAREL.

Investing Activities

During the six months ended June 30, 2011 and 2010, our net cash used in investing activities was $21.8 million and $1.9 million, respectively. In 2011, we invested $19.8 million from the net proceeds of our initial public offering in investment grade commercial paper and corporate bonds with maturities of less than one year. We purchased fixed assets of $2.0 million and $1.9 million during the six months ended June 30, 2011 and 2010, respectively, primarily for the construction of our manufacturing facilities to produce EXPAREL.

Financing Activities

During the six months ended June 30, 2011 and 2010, our net cash provided by financing activities was $38.0 million and $19.3 million, respectively. The net cash provided by financing activities in 2011 was primarily from the issuance of common stock in connection with our initial public offering completed in February 2011. We raised approximately $37.1 million in net proceeds in this offering, after deducting $4.9 million in offering expenses of which $0.9 million was paid prior to December 31, 2010. The net cash provided by financing activities in 2010 was primarily due to the issuance of secured notes of $14.1 million to certain of our existing investors and the borrowing on a new credit facility of $5.6 million.

Debt Facilities

As of June 30, 2011, we had outstanding principal debt of $26.3 million under the Hercules Credit Facility. The Hercules Credit Facility provides for an “interest only period” when no principal amounts are due and payable. The interest only period runs initially from November 24, 2010 through August 31, 2011, but has been extended, at our request, to November 30, 2011. Following the end of the interest only period, the term loan is to be repaid in 33 equal monthly installments of principal and interest beginning on the first business day after the month in which the interest only period ends. As of June 30, 2011, we were in compliance with all covenants under the facility.

Upon completion of our initial public offering in February 2011, all principal and accrued interest on the convertible and secured notes (other than the 2010 Convertible Notes) converted into 3,264,777 shares of our common stock at a conversion price of $13.44, pursuant to an agreement entered into in October 2010 between us and the holders of the convertible and secured notes. The 2010 Convertible Notes were converted into 1,071,428 shares of our common stock at a conversion price equal to our initial public offering price of $7.00 per share. The table below shows our indebtedness and the number of shares of common stock that our indebtedness was converted into:


Notes	Conversion Shares
2009 Convertible Notes		871,635
2009 Secured Notes		927,881
2010 Secured Notes		1,156,606
HBM Secured Notes		308,655
2010 Convertible Notes		1,071,428

Royalty Interests Assignment Agreement

On March 23, 2007, we entered into the Amended and Restated Royalty Interests Assignment Agreement with Paul Capital, pursuant to which we assigned to Paul Capital the right to receive up to approximately 20% of our royalty payments from DepoCyt(e) and DepoDur. The original agreement was entered into prior to the Acquisition by SkyePharma Holdings, Inc. in order to monetize certain royalty payments from DepoCyt(e) and DepoDur. In connection with the Acquisition, the original agreement with Paul Capital was amended and restated and the responsibility to pay the royalty interest in product sales of DepoCyt(e) and DepoDur was transferred to us and we were required to make payments to Paul Capital upon the occurrence of certain events. To secure our obligations to Paul Capital, we granted Paul Capital a security interest in collateral which includes the royalty payments we are entitled to receive with respect to sales of DepoCyt(e) and DepoDur, as well as to bank accounts to which such payments are deposited. Under our arrangement with Paul Capital, upon the occurrence of certain events, including if we experience a change of control, undergo certain bankruptcy events of us or our subsidiary, transfer any or substantially all of our rights in DepoCyt(e) and/or DepoDur, transfer all or substantially all of our assets, breach certain of the covenants, representations or warranties under the Amended and Restated Royalty Interests Assignment Agreement, or sales of DepoCyt(e) and/or DepoDur are suspended due to an injunction or if we elect to suspend sales of DepoCyt(e) and/or DepoDur as a result of a lawsuit filed by certain third parties, Paul Capital may require us to repurchase the rights we assigned to it at a cash price equal to (a) 50% of all cumulative payments made by us to Paul Capital under the Amended and Restated Royalty Interests Assignment Agreement during the preceding 24 months, multiplied by (b) the number of days from the date of Paul Capital’s exercise of such option until December 31, 2014, divided by 365. Under the terms of the Amended and Restated Royalty Interests Assignment Agreement, our initial public offering did not constitute a change of control.

Future Capital Requirements

As of June 30, 2011, we had cash and cash equivalents and short-term investments of $47.2 million. If we receive FDA approval of EXPAREL, we believe our existing cash and cash equivalents and revenue from product sales will be sufficient to enable us to fund our operating expenses, capital expenditure requirements and service our indebtedness through the end of 2011. If we do not receive approval of EXPAREL, we believe that we have sufficient cash to fund us beyond the next 12 months. However, no assurance can be given that this will be the case, and we may require additional debt or equity financing to meet our working capital requirements. We expect that the net proceeds from the offering will be sufficient for our planned manufacture and commercialization of EXPAREL in the United States. Our need for additional external sources of funds will depend significantly on the level and timing of our sales of EXPAREL. Moreover, changing circumstances may cause us to expend cash significantly faster than we currently anticipate, and we may need to spend more cash than currently expected because of circumstances beyond our control.

Our expectations regarding future cash requirements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments that we make in the future. We have no current agreements or commitments for any material acquisitions or licenses of any products, businesses or technologies. We may need to raise substantial additional capital in order to engage in any of these types of transactions.

We expect to continue to incur substantial additional operating losses as we seek FDA approval for and commercialize EXPAREL and develop and seek regulatory approval for our other product candidates. If we obtain FDA approval for EXPAREL, we will incur significant sales and marketing and manufacturing expenses. In addition, we expect to incur additional expenses to add operational, financial and information systems and personnel, including personnel to support our planned product commercialization efforts. We also expect to incur significant costs to comply with corporate governance, internal controls and similar requirements applicable to us as a public company.

Our future use of operating cash and capital requirements will depend on many forward-looking factors, including the following:

•

the timing and outcome of the FDA’s review of the NDA for EXPAREL;

•

the extent to which the FDA may require us to perform additional clinical trials for EXPAREL;

•

the costs of our commercialization activities for EXPAREL, if it is approved by the FDA;

•

the cost and timing of expanding our manufacturing facilities and purchasing manufacturing and other capital equipment for EXPAREL and our other product candidates;

•

the scope, progress, results and costs of development for additional indications for EXPAREL and for our other product candidates;

•

the cost, timing and outcome of regulatory review of our other product candidates;

•

the extent to which we acquire or invest in products, businesses and technologies;

•

the extent to which we choose to establish collaboration, co-promotion, distribution or other similar agreements for our product candidates; and

•

the costs of preparing, submitting and prosecuting patent applications and maintaining, enforcing and defending intellectual property claims.

To the extent that our capital resources are insufficient to meet our future operating and capital requirements, we will need to finance our cash needs through public or private equity offerings, debt financings, corporate collaboration and licensing arrangements or other financing alternatives. The covenants under the Hercules Credit Facility and the Amended and Restated Royalty Interests Assignment Agreement and the pledge of our assets as collateral limit our ability to obtain additional debt financing. We have no committed external sources of funds. Additional equity or debt financing or corporate collaboration and licensing arrangements may not be available on acceptable terms, if at all.

If we raise additional funds by issuing equity securities, our stockholders will experience dilution. Debt financing, if available, would result in increased fixed payment obligations and may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Any debt financing or additional equity that we raise may contain terms, such as liquidation and other preferences that are not favorable to us or our stockholders. If we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish valuable rights to our technologies, future revenue streams or product candidates or to grant licenses on terms that may not be favorable to us.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, except for operating leases, or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities.

Critical Accounting Policies and Estimates

For a description of the critical accounting policies that affect our more significant judgments and estimates used in the preparation of our consolidated financial statements, refer to our most recent Annual Report on Form 10-K for the year ended December 31, 2010. There have been no significant changes to our critical accounting policies since December 31, 2010.

Recent Accounting Pronouncements

components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. ASU No. 2011-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 (January 1, 2012 for us) and interim and annual periods thereafter. Early adoption is permitted, and full retrospective application is required. Since this ASU pertains to presentation requirements only, the adoption of this ASU will not have a material impact on our consolidated financial statements.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve our capital to fund operations. We also seek to maximize income from our investments without assuming significant risk. Our exposure to market risk is confined to our cash and cash equivalents. As of June 30, 2011, we had cash and cash equivalents and short-term investments of $47.2 million. We do not engage in any hedging activities against changes in interest rates. Because of the short-term maturities of our cash and cash equivalents and short-term investments, we do not believe that an increase in market rates would have any significant impact on the realized value of our investments, but may increase the interest expense associated with our debt.

We have commercial partners for DepoCyte and DepoDur who sell our products in the EU. Under these agreements, we provide finished goods to our commercial partners in exchange for euro-denominated supply revenue, and we also receive euro-denominated royalties on market sales when the products are sold to end users. Because of these agreements, we are subject to fluctuations in exchange rates, specifically in the relative values of the U.S. dollar and the euro.

Item 4. CONTROLS AND PROCEDURES

(a)

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission (“SEC”) rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on their evaluation with the participation of the Company’s management, as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective.

(b)

Changes in Internal Control over Financial Reporting

In connection with our previously disclosed plan to hire additional employees for our finance and audit functions, in the quarter ended June 30, 2011 we hired an Executive Director, Accounting and Reporting and a Senior Manager, Accounting. Other than the foregoing, there were no other significant changes in our internal controls over financial reporting that have, or are reasonably likely to have, a material effect on our internal control over financial reporting.

(c)

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, do not expect that our disclosure controls or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Pacira have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II—OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

From time to time, we have been and may again become involved in legal proceedings arising in the ordinary course of our business. We are not presently a party to any material litigation and we are not aware of any pending or threatened litigation against us that could have a material adverse effect on our business, operating results, financial condition or cash flows.

Item 1A. RISK FACTORS

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, “Item 1A: Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2010, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K for the year ended December 31, 2010, are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results. There have been no material changes in the risk factors contained in our Annual Report on Form 10-K for the year ended December 31, 2010.

Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Unregistered Sales of Equity Securities

There were no issuances of unregistered shares of capital stock during the three month period covered by this report, ended June 30, 2011

Use of Proceeds

In February 2011, we completed the initial public offering of our common stock pursuant to a registration statement on Form S-1, as amended (File No. 333-170245) that was declared effective on February 2, 2011. Under the registration statement, we registered the offering and sale of an aggregate of 6,900,000 shares of our common stock. An aggregate of 6,000,000 shares of common stock registered under the registration statement were sold at a price to the public of $7.00 per share. Barclays Capital Inc. and Piper Jaffray and Co. acted as joint book running managers of the offering and as representatives of the underwriters. The offering commenced on February 3, 2011 and closed on February 8, 2011. The over-allotment option was not exercised by the underwriters. As a result of our initial public offering, we raised a total of $42.0 million in gross proceeds, and approximately $37.1 million in net proceeds after deducting approximately $4.9 million in underwriting discounts and commissions and estimated offering expenses.

There has been no material change in our planned use of proceeds from the initial public offering from that described in the final prospectus filed with the SEC on February 3, 2011. As of June 30, 2011, we invested $19.8 million of the net proceeds into investment grade commercial paper and corporate bonds with maturities of less than one year. The remaining proceeds are currently held in a liquid operating account with a major bank.
