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 EXPAREL, which consists of bupivacaine encapsulated in DepoFoam, was approved by the United States Food and Drug Administration, or FDA, on October 28, 2011. DepoFoam is also the basis for the Company’s other two FDA-approved commercial products, DepoCyt(e) and DepoDur, which the Company manufactures for its commercial partners.

Pacira Pharmaceuticals, Inc. is the holding company for the California operating subsidiary of the same name, which is also referred to as PPI-California, which was acquired from Skyepharma Holding, Inc. in March 2007, referred to herein as the Acquisition.

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, 2011, filed with the SEC on March 27, 2012.

The consolidated financial statements at March 31, 2012 and for the three months ended March 31, 2012 and 2011 are unaudited, but include 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, 2011 has been derived from the audited financial statements included in the Form 10-K for that year. Certain reclassifications were made to conform to the current presentation. Specifically, for the three months ended March 31, 2011, the Company reclassified $0.3 million of stock-based compensation expense from selling, general and administrative expense to research and development expense. This reclassification had no impact on net loss or stockholders’ equity as previously reported. 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.

Liquidity

Management believes that the Company’s existing cash and cash equivalents, including the $63 million raised in April 2012 (see Note 11, Subsequent Events), short-term investments and revenue from product sales will be sufficient to enable the Company to meet its planned operating expenses, capital expenditure requirements and service its indebtedness through the next twelve months. However, changing circumstances may cause the Company to expend cash significantly faster than currently anticipated, and the Company may need to spend more cash than currently expected because of circumstances beyond its control. The Company expects to continue to incur substantial additional operating losses as it commercializes EXPAREL and develops and seeks regulatory approval for its product candidates.

Table of Contents

Concentration of Major Customers

The Company’s customers are its commercial, distribution and licensing partners. The table below includes the percentage of revenue comprised by the three largest customers in each year presented.

	Three Months Ended
	March 31,		March 31,
	2012		2011
Largest customer	75	%	41	%
Second largest customer	10	%	26	%
Third largest customer	6	%	16	%
	91	%	83	%

No other individual customer accounted for more than 10% of the Company’s revenues for these periods. The Company is dependent on its commercial partners to market and sell DepoCyt(e) and DepoDur, from which a substantial portion of its revenues is derived. The Company’s future revenues from these products are highly dependent on commercial and distribution arrangements.

On January 3, 2012, EKR Therapeutics, Inc, or EKR, delivered a notice to the Company to terminate the licensing, distribution and marketing agreement relating to DepoDur. Pursuant to the terms of the agreement, the termination of the agreement will be effective 180 days from the date of the notice or July 1, 2012. Pursuant to the terms of the agreement, the associated supply agreement will also terminate concurrently with the termination of the agreement. As a result of the termination, the Company is recognizing any unamortized deferred revenue relating to the EKR contract on a straight-line basis through the termination date in July 2012. During the three months ended March 31, 2012, the Company recognized $5.8 million of milestone revenue relating to the EKR agreement in collaborative licensing and development revenue on the consolidated statements of operations.

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 Financial Accounting Standards Board, or 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 and accounts payable approximate their respective fair values due to the short-term maturities of these instruments and debts. The fair value of the Company’s long-term debt is calculated using a discounted cash flow analysis factoring in current market borrowing rates for similar types of borrowing arrangements under a similar credit profile. The carrying amount and fair value of the Company’s long-term debt is as follows (in thousands):

Table of Contents

	Carrying		Fair Value Measurements Using
Financial Liabilities	Value		Level 1		Level 2		Level 3
March 31, 2012
Long-term debt- current and long-term	$	25,565	$	—	$	27,016	$	—
December 31, 2011			—		—		—
Long-term debt- current and long-term	$	26,250	$	—	$	27,929	$	—

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 gains (losses) from the Company’s short-term investments are captured in other comprehensive loss. All of the Company’s short-term investments are classified as available for sale investments and determined to be Level 2 instruments. The fair value of the commercial paper is measured based on a standard industry model that uses the 3-month Treasury bill rate as an observable input. The fair value of the corporate bonds is principally measured or corroborated by trade data for identical issues or that of comparable securities in which related trading activity is not sufficiently frequent to be considered a Level 1 input. At March 31, 2012, the Company had $29.6 million invested in short-term investments which were rated A or better by Standard & Poor’s and had maturities ranging from 123 to 321 days from date of purchase.

The following summarizes the Company’s short-term investments at March 31, 2012 and December 31, 2011 (in thousands):

Total	$	29,970	$	25	$	(10	)	$	29,985

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 March 31, 2012, two customers accounted for 59% and 37% of the Company’s trade accounts receivable. As of December 31, 2011, two customers accounted for 56% and 41% of the Company’s accounts receivable.

At March 31, 2012, the blended interest rate on the Hercules Note was 11.94%.

The Hercules Note provided for an “interest only period” when no principal amounts were due and payable that expired on February 29, 2012. Following the end of the interest only period, the term loan is being repaid in 33 monthly installments of principal and interest beginning on the first business day after the month in which the interest only period ends. See Note 11, Subsequent Events for discussion of the refinancing of the Hercules Note.

Note 8—STOCKHOLDERS’ EQUITY

Stock-Based Compensation

The Company recognized stock-based compensation expense in its consolidated statements of operations as follows (in thousands):

Table of Contents

	Three Months Ended
	March 31,
	2012		2011
Cost of revenues	$	89	$	83
Research and development	177		416
Selling, general and administrative	446		473
Total	$	712	$	972

The terms of the stock options granted in September and December 2010 stipulated that they may be exercised only upon the completion of an initial public offering. Consequently, the expense associated with these options was deferred until the successful completion of the Company’s initial public offering in February 2011.

Stock Incentive Plans

The Company’s 2011 stock incentive plan, or 2011 Plan, contains an “evergreen” provision, which allows for an increase in the number of shares available for issuance under the 2011 Plan on the first day of each calendar year from 2012 through 2015. On January 1, 2012, the evergreen provision increased the number of shares in the pool by 557,880 shares. The following table contains information about the Company’s plans at March 31, 2012:

Plan	Awards Reserved for Issuance	Awards Issued	Awards Available for Grant
2011 Plan	992,347	544,084	448,263
2007 Plan	2,112,190	2,112,190	—

Note 9—LOSS PER SHARE

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. Diluted net loss per share is calculated by dividing net loss available to common stockholders by the weighted average number of common stock and dilutive common stock equivalents 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). 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

On April 17, 2012, the Company sold 6,000,000 shares of common stock at a price of $9.75 per share in a registered public offering. The Company raised approximately $55 million in net proceeds after deducting underwriting discounts and offering expenses. On April 27, 2012, the underwriters exercised the overallotment option for 900,000 shares of common stock at a price of $9.75 per share, which provided an additional $8 million in net proceeds after deducting underwriting discounts and offering expenses.

On May 2, 2012, the Company entered into a definitive loan and security agreement, or the Loan Agreement, with Oxford Finance LLC, or the Lender, and borrowed the principal amount of $27.5 million, or the Loan Facility, at a fixed rate of 9.75%. with the first principal payment due December 31, 2013. Payments under the Loan Agreement are interest-only in arrears through November 30, 2013, followed by 30 equal monthly payments of principal and interest. In addition, a payment equal to 6% of the Loan Facility will be due on the final payment date, or such earlier date as specified in the Loan Agreement. The proceeds from the Loan Agreement were used by the Company to repay all of its outstanding obligations with respect to the Hercules Credit Facility. The Company’s principal payments are due under the Loan Agreement as follows: $0.8 million in 2013, $10.3 million in 2014, $11.3 million in 2015 and $5.1 million in 2016.

The Company’s obligations under the Loan Agreement are secured by a first priority security interest in substantially all of its assets, other than its intellectual property. The Company has also agreed not to pledge or otherwise encumber its intellectual property assets, except for permitted liens or to the extent the intellectual property constitutes royalty collateral, as such terms are defined in the Loan Agreement and except as otherwise provided in the Loan Agreement.

If the Company repays all or a portion of the Loan Facility prior to maturity, it will pay the Lender a prepayment fee based on a percentage of the then outstanding principal balance equal to: 3.00% if the prepayment occurs prior to or on the first anniversary of the funding date, 2.00% if the prepayment occurs after the first anniversary of the funding date but prior to or on the second anniversary of the funding date, or 1.00% if the prepayment occurs after the second anniversary of the funding date.

The Loan Agreement includes customary affirmative and restrictive covenants for transactions of this type and customary events of default, including the following events of default: payment defaults, breaches of covenants, judgment defaults, cross defaults to certain other contracts, the occurrence of certain events under the Company’s royalty agreements, certain events with respect to governmental approvals if such events could cause a material adverse change, a material impairment in the perfection or priority of the Lender’s security interest or in the value of the collateral, a material adverse change in the business, operations or condition of the Company or any of its subsidiaries and a material impairment of the prospect of repayment of the loans. Upon the occurrence of an event of default, a default increase in the interest rate of an additional 5.00% may be applied to the outstanding loan balance and the Lender may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan Agreement.

In connection with the Loan Agreement, the Company issued to the Lender warrants that are exercisable for an aggregate of 162,885 shares of its common stock at a per share exercise price of $10.97. Each warrant may be exercised on a cashless basis in whole or in part. The warrants will terminate on the earlier of ten years from the issuance date or the closing of certain merger or consolidation transactions in which the consideration is cash or stock of a publicly traded acquiror, or a combination thereof.

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.

On October 28, 2011, the United States Food and Drug Administration, or FDA, approved our New Drug Application, or NDA, for our lead product candidate, EXPAREL, a liposome injection of bupivacaine, an amide-type local anesthetic, indicated for administration into the surgical site to produce postsurgical analgesia. We have developed a sales force entirely dedicated to commercializing EXPAREL comprised of approximately 60 representatives, seven regional managers and a national sales manager. We have developed this sales force pursuant to a contract with Quintiles Commercial US, Inc., a division of Quintiles, Inc., or Quintiles, and under the terms of this contract we have the flexibility to hire all or a portion of the sales force dedicated to commercializing EXPAREL as full-time employees of Pacira, upon 60 days notice to Quintiles. We launched EXPAREL in April 2012.

Our two other marketed products, DepoCyt(e) and DepoDur, and our proprietary DepoFoam extended release drug delivery technology, which were acquired as part of the acquisition of our California operating subsidiary, referred to herein as the Acquisition, Pacira Pharmaceuticals, Inc., or 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. On January 3, 2012, EKR delivered a notice to terminate the licensing, distribution and marketing agreement with us relating to DepoDur. Pursuant to the terms of the agreement, the termination of the agreement will be effective 180 days from the date of notice or July 1, 2012. Pursuant to the terms of the agreement, the associated supply agreement will also terminate concurrently with the termination of the agreement. As a result, we expect the supply and royalty revenue from DepoDur to decrease in the future and we do not expect to re-license out the rights to DepoDur.

Table of Contents

We do not expect our currently marketed products, other than EXPAREL, to generate revenue that is sufficient for us to achieve profitability because we expect to continue to incur significant expenses as we commercialize EXPAREL and advance the development of 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

First Commercial Sale of EXPAREL

In April 2012, we completed our first commercial sale of EXPAREL, triggering a $10.0 million payment obligation to Skyepharma in connection with the Acquisition. Payment was made on April 19, 2012.

Consulting Agreement

In April 2012, we entered into an amended and restated consulting agreement with Gary Pace, whereby Dr. Pace will provide consulting services to us in the manufacturing area. Dr. Pace is compensated at the rate of $10,000 per month and received an option to purchase 20,000 shares of our stock pursuant to the consulting arrangement.

Offering of Common Stock

On April 17, 2012, we sold 6,000,000 common shares at a price of $9.75 per share in a registered public offering of common stock. We received approximately $55 million in net proceeds after deducting underwriting discounts and offering expenses. On April 27, 2012, the underwriters exercised the overallotment option for 900,000 common shares at a price of $9.75 per share, which provided an additional $8 million in net proceeds after deducting underwriting discounts and offering expenses.

Refinancing of Hercules Note

On May 2, 2012, we entered into a definitive loan and security agreement, or Loan Agreement, with Oxford Finance LLC, who we refer to as the Lender, and borrowed the principal amount of $27.5 million, at a fixed rate of 9.75%. with the first principal payment due December 31, 2013. Payments under the Loan Agreement are interest-only in arrears through November 30, 2013, followed by 30 equal monthly payments of principal and interest. In addition, a final payment equal to 6% of the Loan Facility will be due on the final payment date, or such earlier date as specified in the Loan Agreement.

Our obligations under the Loan Agreement are secured by a first priority security interest in substantially all of our assets, other than our intellectual property. We have also agreed not to pledge or otherwise encumber our intellectual property assets, except for permitted liens or to the extent the intellectual property constitutes royalty collateral, as such terms are defined in the Loan Agreement and except as otherwise provided in the Loan Agreement.

If we repay all or a portion of the Loan Facility prior to maturity, we will pay the Lender a prepayment fee based on a percentage of the then outstanding principal balance equal to: 3.00% if the prepayment occurs prior to or on the first anniversary of the funding date, 2.00% if the prepayment occurs after the first anniversary of the funding date but prior to or on the second anniversary of the funding date, or 1.00% if the prepayment occurs after the second anniversary of the funding date.

The Loan Agreement includes customary affirmative and restrictive covenants for transactions of this type and customary events of default, including the following events of default: payment defaults, breaches of covenants, judgment defaults, cross defaults to certain other contracts, the occurrence of certain events under our royalty agreements, certain events with respect to governmental approvals if such events could cause a material adverse change, a material impairment in the perfection or priority of the Lender’s security interest or in the value of the collateral, a material adverse change in the business, operations or condition of us or any of our subsidiaries and a material impairment of the prospect of repayment of the loans. Upon the occurrence of an event of default, a default increase in the interest rate of an additional 5.00% may be applied to the outstanding loan balance and the Lender may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan Agreement.

In connection with the Loan Agreement, we issued to the Lender warrants that are exercisable for an aggregate of 162,885 shares of our common stock at a per share exercise price of $10.97. Each warrant may be exercised on a cashless basis in whole or in

part. The warrants will terminate on the earlier of ten years from the issuance date or the closing of certain merger or consolidation transactions in which the consideration is cash or stock of a publicly traded acquiror, or a combination thereof.

The proceeds from the Loan Agreement were used by us to repay all of our outstanding obligations with respect to the credit facility we previously entered into with Hercules Technology Growth Capital, Inc. and Hercules Technology II, L.P., as lenders, or the Hercules Credit Facility.

Results of Operations

Comparison of Three Months Ended March 31, 2012 and 2011

Revenues

The following table sets forth a summary of our supply and royalty revenue and collaborative licensing and development revenue during the periods indicated (in thousands):

	Three Months Ended				%
	March 31,				Increase/
	2012		2011		Decrease
Supply and royalty revenue:
DepoCyt(e)	$	1,250	$	2,603	(52	)%
DepoDur	64		50		28	%
Total supply and royalty revenue	1,314		2,653		(50	)%
Collaborative licensing and development revenue	6,490		1,210		436	%
Total revenues	$	7,804	$	3,863	102	%

Total revenues increased by $3.9 million, or 102%, to $7.8 million in the three months ended March 31, 2012 as compared to $3.9 million in the three months ended March 31, 2011 primarily due to the recognition of $5.8 million of collaborative licensing and development revenue in connection with the termination of the licensing, distribution and marketing agreement with EKR for the DepoDur product. We are recognizing any unamortized deferred revenue related to milestones received under the agreement over the remaining contract period through July 2012. This was partially offset by a decrease in supply and royalty revenue of $1.3 million due to a lower number of DepoCyt(e) lot sales to our commercial partners.

Cost of Revenues

The following table provides information regarding our cost of revenues during the periods indicated (in thousands):

	Three Months Ended				%
	March 31,				Increase/
	2012		2011		Decrease
Cost of goods sold	$	6,254	$	3,288	90	%
Cost of collaborative licensing and development revenue	241		379		(36	)%
Total cost of revenues	$	6,495	$	3,667	77	%

Cost of revenues increased by $2.8 million, or 77%, to $6.5 million in the three months ended March 31, 2012 as compared to $3.7 million the three months ended March 31, 2011. The increase was primarily driven by excess capacity relating to running two cGMP facilities that have a substantial level of infrastructure cost, including the EXPAREL production line which was put into service during the fourth quarter of 2011 with the majority of all operating expenses expensed as incurred due to commercial manufacturing

Table of Contents

challenges. EXPAREL product was manufactured for commercial use beginning in March 2012.

Research and Development Expense

The following table provides information regarding our research and development expenses during the periods indicated (in thousands):

	Three Months Ended				%
	March 31,				Increase/
	2012		2011		Decrease
Research and development expense	$	1,294	$	3,795	(66	)%

Research and development expenses decreased by $2.5 million, or 66%, to $1.3 million in the three months ended March 31, 2012 as compared to $3.8 million in the three months ended March 31, 2011 due to the shift of EXPAREL production line expenses from research and development expenses to cost of revenues following the approval of EXPAREL by the FDA in October 2011. Research and development expenses in the three months ended March 31, 2012 primarily resulted from our dose ranging EXPAREL nerve block trial and a potential new manufacturing process for EXPAREL.

In the three months ended March 31, 2012 and 2011, research and development expenses attributable to EXPAREL were $1.3 million or 100%, and $3.7 million or 99%, of total research and development expenses, respectively.

Selling, General and Administrative Expense

The following table provides information regarding our selling, general and administrative expenses during the periods indicated (in thousands):

	Three Months Ended				%
	March 31,				Increase/
	2012		2011		Decrease
General and administrative	$	3,644	$	2,375	53	%
Sales and marketing	7,508		1,148		554	%
Total selling, general and administrative expense	$	11,152	$	3,523	217	%

Selling, general and administrative expenses increased by $7.6 million, or 217%, to $11.1 million in the three months ended March 31, 2012 as compared to $3.5 million in the three months ended March 31, 2011 due to the following:

· sales and marketing expenses increased by $6.4 million primarily due to the cost of our sales force entirely dedicated to commercializing EXPAREL, which was comprised of approximately 60 representatives, seven regional managers and a national sales manager, and promotional costs to support the launch of EXPAREL including simulcasts, speaker trainings, educational programs, publications, promotional materials and health outcomes collaboratives and business analytics; and

· general and administrative expenses increased by $1.2 million due to the increase in headcount and consulting costs to support our operations as a public company and costs to support our information technology structure.

Other Income (Expense)

The following table provides information regarding our other income (expense) during the periods indicated (in thousands):

Table of Contents

	Three Months Ended						%
	March 31,						Increase/
	2012			2011			Decrease
Interest income	$	63		$	29		117	%
Interest expense	(514		)	(2,481		)	(79	)%
Royalty interest obligation	(282		)	(311		)	(9	)%
Other, net	(24		)	110			(122	)%
Total other (expense) net	$	(757	)	$	(2,653	)	(71	)%

Total other (expense) income, net decreased by $1.9 million, or 71%, to $0.8 million in the three months ended March 31, 2012 as compared to $2.7 million in the three months ended March 31, 2011 primarily due to a $1.9 million decrease in interest expense. The decrease in interest expense is due to the following:

· $1.1 million of remaining amortization recognized during the three months ended March 31, 2011 associated with convertible notes we issued in 2010 that were converted into common stock upon the closing of our initial public offering in February 2011;

· $0.3 million of interest expense recognized during the three months ended March 31, 2011 on our convertible and secured notes that were converted into common stock upon the closing our initial public offering in February 2011; and

· $0.4 million of capitalized interest recognized during the three months ended March 31, 2012 for the construction of our expanded manufacturing site for EXPAREL.

This decrease in interest expense was partially offset by $0.1 million increase in other, net. We received a research grant in February 2011 established by the Internal Revenue Service and the Secretary of Health and Human Services under the Patient Protection and Affordable Care Act of 2010.

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 from the sale of convertible preferred stock and common stock, secured and unsecured notes and borrowings under debt facilities, supply and royalty revenue and collaborative licensing and development revenue. We raised approximately $37.1 million in net proceeds through an initial public offering completed on February 8, 2011 and approximately $49.0 million in net proceeds through a follow-on offering completed on November 21, 2011. Additionally, we received approximately $63 million in net proceeds through an offering of common stock in April 2012. We have generated limited supply revenue and royalties, and we do not anticipate generating any revenues from the sale of EXPAREL, until the second quarter of 2012. We have incurred losses and generated negative cash flows from operations since inception. As of March 31, 2012, we had an accumulated deficit of $192.1 million, cash and cash equivalents and short-term investments of $54.8 million and working capital of $43.1 million.

Summary of Cash Flows

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

Table of Contents

	Three Months Ended
	March 31,
	2012			2011
Net cash provided by (used in):
Operating activities	$	(17,545	)	$	(3,987	)
Investing activities	(2,530		)	(832		)
Financing activities	(880		)	38,017
Net (decrease) increase in cash and cash equivalents	$	(20,955	)	$	33,198

Operating Activities

During the three months ended March 31, 2012 and 2011, our net cash used in operating activities was $17.6 million and $4.0 million, respectively. The $13.6 million increase in net cash used in operating activities was driven by (i) higher sales and marketing expenses in preparation of the launch of EXPAREL in April 2012 including the hiring of our sales force dedicated to EXPAREL, (ii) increased costs in our manufacturing facilities, (iii) a decrease in supply and royalty revenue due to lower lot sales to our commercial partners, and (iv) a $1.5 million up-front payment received in January 2011 from our development partner Novo.

Investing Activities

During the three months ended March 31, 2012 and 2011, our net cash used in investing activities was $2.5 million and $0.8 million, respectively, primarily for the purchase of fixed assets relating to the construction of our manufacturing lines for EXPAREL. We also had $0.4 million of short-term investments mature during the three months ended March 31, 2012.

Financing Activities

During the three months ended March 31, 2012, net cash used in financing activities was $0.9 million compared to net cash provided by financing activities of $38.0 million during the three months ended March 31, 2011. The net cash used in financing activities in 2012 was primarily from the principal repayment of debt on the Hercules Credit Facility and costs for the refinancing of the Hercules debt, offset by proceeds from exercise of stock options. 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 the initial public offering, after deducting $4.9 million in offering expenses of which $0.9 million was paid prior to December 31, 2010.

Debt Facilities

As of March 31, 2012, we had $25.6 million in outstanding principal debt under the Hercules Credit Facility. The Hercules Credit Facility provides for an “interest only period” when no principal amounts are due and payable. Following the end of the interest only period on February 28, 2012, the term loan is being repaid in 33 monthly installments of principal and interest beginning on March 1, 2012. As of March 31, 2012, we were in compliance with all covenants under the facility.

On May 2, 2012, we entered into a Loan Agreement with Oxford Finance LLC and borrowed the principal amount of $27.5 million, at a fixed rate of 9.75% with the first principal payment due December 31, 2013. The proceeds from the Loan Agreement were used by us to repay all of our outstanding obligations with respect to the Hercules Credit Facility.

Future Capital Requirements

As of March 31, 2012, we had cash and cash equivalents and short-term investments of $54.8 million and we received approximately $63 million of net proceeds from a registered offering of our common stock in April 2012. We believe that our existing cash and cash equivalents, including the $63 million raised in April 2012, short-term investments and revenue from product sales will be sufficient to enable us to meet our planned operating expenses, capital expenditure requirements and service our indebtedness for the next twelve months. However, 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 understandings, 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.

Table of Contents

We expect to continue to incur substantial additional operating losses as we commercialize EXPAREL and develop and seek regulatory approval for our product candidates. We will continue to incur significant sales and marketing and manufacturing expenses due to the commercialization of EXPAREL. 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 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 level and timing of our sales of EXPAREL;

· the costs of our commercialization activities for EXPAREL;

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

· the costs of performing additional clinical trials for EXPAREL, including the pediatric trials required by the FDA as a condition of approval;

· 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. Additional 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 additional 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. None of our off-balance sheet arrangements have, or are reasonably likely to have, a current or future material effect on our financial condition or changes in financial condition.

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, 2011. There have been no significant changes to our critical accounting policies since December 31, 2011.

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 President and 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

No change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended March 31, 2012 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(c) Inherent Limitations on Effectiveness of Controls

Our management, including our President and 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.

Item 1A. RISK FACTORS

AMENDED AND RESTATED CONSULTING AGREEMENT

RECIPIENT:	Gary Pace , Ph.D

EFFECTIVE DATE:	April 3, 2012

This Consulting Agreement (the “ Agreement ”) is entered into this day, April 3, 2012, by and between Pacira Pharmaceuticals, Inc ., a California corporation, having its principal place of business at 10450 Science Center Drive, San Diego, California 92121 (“ Company ”), and Gary Pace located at the address listed above (the “ Consultant ”), and is made with respect to the following recitals and agreements:

WHEREAS , WHEREAS, as of June 2, 2011 (the Effective Date ) the Company and Consultant entered into a Consulting Agreement; (the “Original Agreement” ); and

WHEREAS , the Company and Consultant wish to amend and restate the Original Agreement to read as set forth herein.

NOW, THEREFORE , in consideration of the mutual covenants and promises described below, the Original Agreement is hereby amended and restated to read, and the company and Consultant agree, as follows:

1. Services; Fees .

a) Consultant is hereby retained as an independent contractor to provide the services described in Exhibit A hereto (the “ Services ”). Consultant shall receive fees for such Services and reimbursement for expenses as set forth in Exhibit A hereto. Such Services shall be performed as requested from time to time by Company’s chief executive officer, or as otherwise set forth on Exhibit A .

b) Consultant shall diligently perform the Services in full compliance with the highest professional standards of practice in the industry and applicable laws. Anything to the contrary contained in this Agreement notwithstanding, Consultant agrees and acknowledges that during the Term there is neither a minimum amount of Services for which Company is obligated to engage Consultant, nor shall this Agreement be construed as limiting in any way Company’s right to contract for similar services with any other party. In no event shall this Agreement be construed as obligating Company to pay any amounts for Services performed under this Agreement unless (i) Company actually engages Consultant to perform Services pursuant to this Agreement, and Consultant actually performs such Services, and (ii) each such engagement to perform Services is evidenced by Exhibit A or other written agreement between the parties prior to the commencement of such Services.

c) In consideration of the Services, Consultant shall receive the fees set forth on Exhibit A (the “ Consulting Fees ”). Consultant represents that the compensation: (i) is payment in full for the Services, and (ii) reflects the fair market value of the services described herein, commensurate with the fees charged by Consultant for providing similar services to other entities.

2. Term . The initial term of this Agreement shall commence on the date hereof and continue for a period of one (1) year. Consultant’s services shall be rendered as requested by Company and in a manner satisfactory to Company. This Agreement may be cancelled by either party upon giving thirty (30) days prior written notice. Upon expiration or termination of this Agreement, Consultant shall only be entitled and Company only obligated to pay for any Consulting Fee(s) due to Consultant for Services actually rendered and non-cancellable expenses incurred up to that point in accordance with the terms and conditions of this Agreement, and nothing more. Notwithstanding the foregoing, in the event Company terminates this Agreement as a result of Consultant’s failure to comply with the representations and warranties set forth herein, Company shall be entitled to withhold payment for Services previously rendered. Sections 4 , 5 , 7 , 9 , and 10 shall survive termination or expiration of this Agreement for any reason.

3. Representations and Warranties of Consultant . Consultant represents and warrants that Consultant has the requisite expertise, ability and legal right to render the consulting services, and will perform the consulting services in an efficient manner and in accordance with the terms of this Agreement. Consultant shall abide by all laws, rules and regulations that apply to the performance of the consulting services and when on Company premises, will comply with Company’s policies with respect to conduct of visitors. Consultant represents and warrants that Consultant is not and has not been: (i) excluded from participation in, or otherwise ineligible to participate in a “Federal Health Care Program” (as defined in 42 U.S.C. § 1320a-7b(f)) or in any other government payment program; (ii) listed on the General Services Administration’s List of parties Excluded from Federal Procurement and Nonprocurement Programs; or (iii) debarred under the Generic Drug Enforcement Act of 1992 (the “GDE Act”) (21 U.S.C. § 335(a) and (b)). To the best of Consultant’s knowledge, Consultant represents and warrants that Consultant has not engaged in any activity that could lead Consultant to become excluded or debarred as set forth above. Consultant further represents and warrants that Consultant does not and will not use in any capacity the services of any person excluded or debarred as set forth above. If Consultant is debarred or excluded as set forth above, during the Term, Consultant agrees to immediately notify Company, and this Agreement shall automatically terminate as of the date of such exclusion or debarment, without the requirement of notice from Company. Consultant further represents and warrants that in providing the Services, Consultant shall be responsible for Consultant’s own compliance with all applicable local, state and federal laws and regulations.

4. Confidentiality .

Confidential Information shall also include information belonging to a third party which Company is obligated to keep confidential from others.

(b) Consultant agrees, at all times, to (i) regard and preserve as confidential such Confidential Information using the same standard of care as it uses to protect its own confidential information, (ii) not use the Confidential Information for any purpose other than as necessary to perform the Services, and (iii) to refrain from publishing, distributing, or disclosing any part of such Confidential Information to a third party without prior written consent of Company. Consultant further agrees, at all times, to refrain from any other acts or omissions that would reduce the value of such Confidential Information to Company. Consultant will immediately notify Company if it learns that Confidential Information has been disclosed or is about to be disclosed in violation of this Agreement, whether by

Consultant’s acts, acts of third parties, law, regulation or court order, and shall cooperate with Company’s efforts to prevent or limit unauthorized disclosure of Confidential Information.

(c) Upon termination of this Agreement, Consultant agrees to promptly surrender to Company all documents or items which are the property of Company or which contain or comprise such Confidential Information.

(d) Consultant’s duties of confidence to Company and other duties pursuant to this Agreement, shall survive the termination of this Agreement for any reason.

(d) All of Company’s patents, copyrights, trade secrets and other intellectual property rights relating to the subject matter of this Agreement that were developed by Company prior to this Agreement or independent thereof shall be owned by Company and Consultant shall have no ownership, license, or other use rights therein except as set forth in this Agreement.

(e) Consultant hereby assigns to the Company all of Consultant’s intellectual property rights (including copyrights, patents, and trademarks embodied in any Inventions or Works) that may arise from Consultant’s engagement by the Company.

and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of patents, copyright and mask work registrations thereon with the same legal force and effect as if executed by the Consultant.

EXHIBIT A

PAYMENTS SUBJECT TO SECTION 409A

1. Subject to this Exhibit A , any severance payments and benefits that may be due under the Agreement shall begin only upon the date of the Executive’s “separation from service” (determined as set forth below) which occurs on or after the termination of the Executive’s employment. The following rules shall apply with respect to distribution of the severance payments and benefits, if any, to be provided to the Executive under the Agreement, as applicable:

(a) It is intended that each installment of the severance payments and benefits under the Agreement provided under shall be treated as a separate “payment” for purposes of Section 409A. Neither the Company nor the Executive shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A.

(b) If, as of the date of the Executive’s “separation from service” from the Company, the Executive is not a “specified employee” (within the meaning of Section 409A), then each installment of the severance payments or benefits shall be made on the dates and terms set forth in the Agreement.

(c) If, as of the date of the Executive’s “separation from service” from the Company, the Executive is a “specified employee” (within the meaning of Section 409A), then:

(i) Each installment of the severance payments and benefits due under the Agreement that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when the Executive’s separation from service occurs, be paid within the short-term deferral period (as defined under Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and shall be paid at the time set forth in the Agreement; and

(ii) Each installment of the severance payments and benefits due under the Agreement that is not described in this Exhibit A , Section 1(c)(i) and that would, absent this subsection, be paid within the six-month period following the Executive’s “separation from service” from the Company shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, the Executive’s death), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following the Executive’s separation from service and any subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment of payments and benefits if and to the maximum extent that that such installment is deemed to be paid under a

separation pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation from service). Any installments that qualify for the exception under Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of the Executive’s second taxable year following the taxable year in which the separation from service occurs.

2. The determination of whether and when the Executive’s separation from service from the Company has occurred shall be made and in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h). Solely for purposes of this Exhibit A , Section 2, “Company” shall include all persons with whom the Company would be considered a single employer under Section 414(b) and 414(c) of the Code.

3. The Company makes no representation or warranty and shall have no liability to the Executive or to any other person if any of the provisions of the Agreement (including this Exhibit) are determined to constitute deferred compensation subject to Section 409A but that do not satisfy an exemption from, or the conditions of, that section.

(60) days following the Termination Date. The provision of payments and benefits pursuant to this Section shall be subject to the terms and conditions set forth in Exhibit A .

(d) Definitions .

(ii) “ Cause ” means (A) the Employee’s failure to substantially perform her duties to the Company after there has been delivered to the Employee written notice setting forth in detail the specific respects in which the Chief Financial Officer and/or Chief Executive Officer believes that the Employee has not substantially performed her duties and, if the Company reasonably considers the situation to be correctable, a demand for substantial performance and opportunity to cure, giving the Employee thirty (30) calendar days after he receives such notice to correct the situation; (B) the Employee’s having engaged in fraud, misconduct, dishonesty, gross negligence or having otherwise acted in a manner injurious to the Company or in intentional disregard for the Company’s best interests; (C) the Employee’s failure to follow reasonable and lawful instructions from the Chief Financial Officer and/or Chief Executive Officer and the Employee’s failure to cure such failure after receiving twenty (20) days advance written notice; (D) the Employee’s material breach of the terms of this Agreement or the Employee Proprietary Information and Inventions Assignment Agreement or any other similar agreement that may be in effect from time to time; or (E) the Employee’s conviction of, or pleading guilty or nolo contendere to, any misdemeanor involving dishonesty or moral turpitude or related to the Company’s business, or any felony.

(e) Benefits Continuation . If the Employee’s employment is terminated pursuant to Section 3(b) or Section 3(c) and provided that the Employee is eligible for and elects to continue receiving group health and dental insurance pursuant to the federal “COBRA” law, 29 U.S.C. § 1161 et seq. , the Company will, for a twelve (12) month period following the Payment Commencement Date (the “ Benefits Continuation Period ”), continue to pay the share of the premium for such coverage that is paid by the Company for active and similarly-situated employees who receive the same type of coverage. The remaining balance of any premium costs shall be paid by the Employee on a monthly basis for as long as, and to the extent that, the Employee remains eligible for COBRA continuation. Notwithstanding the above, in the event the Employee becomes eligible for health insurance benefits from a new employer during the Benefits Continuation Period, the Company’s obligations under this Section 3(e) shall immediately cease and the Employee shall not be entitled to any additional monthly premium payments for health insurance coverage. Similarly, in the event the Employee becomes eligible for dental insurance benefits from a new employer during the Benefits Continuation Period, the Company’s obligations under this Section 3(e) shall immediately cease and the Employee shall not be entitled to any additional monthly premium payments for dental insurance.

The term “ Total and Permanent Disability ” shall mean the existence of a permanent physical or mental illness or injury, which renders the Employee incapable of performing any material obligations or terms of this Agreement. Any dispute regarding the existence of a Total and Permanent Disability shall be resolved by a panel of three (3) physicians, one selected by Company, one selected by the Executive, and the third selected by the other two physicians. A termination of employment pursuant to this Section 3(f) shall constitute a termination for Cause.

4. At-Will Employment . The Employee will be an “at-will” employee of the Company, which means the employment relationship can be terminated by either the Employee or the Company for any reason, at any time, with or without prior notice and with or without cause. The Company makes no promise that the Employee’s employment will continue for any particular period of time, nor is there any promise that it will be terminated only under particular circumstances. No raise or bonus, if any, shall alter the Employee’s status as an “at-will” employee or create any implied contract of employment. Discussion of possible or potential benefits in future years is not an express or implied promise of continued employment. No manager, supervisor or officer of the Company has the authority to change the Employee’s status as an “at-will” employee. The “at-will” nature of the employment relationship with the Employee can only be altered by a written resolution approved by the Board.

5. Non-Solicitation .

The Employee represents that the Employee has no other outstanding commitments inconsistent with any of the terms of this Agreement or the services to be rendered to the Company. While employed by the Company, the Employee shall

not, directly or indirectly, whether as a partner, employee, creditor, shareholder, or otherwise, promote, participate or engage in any activity or other business competitive with the Company’s business. The Employee shall not invest in any company or business which competes in any manner with the Company, except those companies whose securities are listed on reputable securities exchanges in the United States or European Union.

9. Miscellaneous .

(c) Assignment . This Agreement and all rights hereunder are personal to the Employee and may not be transferred or assigned by the Employee at any time. The Company may assign its rights, together with its obligations hereunder, to any parent, subsidiary, affiliate or successor, or in connection with any sale, transfer or other disposition of all or substantially all of its business and assets; provided , however , that any such assignee assumes the Company’s obligations hereunder.

(d) Withholding . All sums payable to the Employee hereunder shall be reduced by all federal, state, local and other withholding and similar taxes and payments required by applicable law.

(e) Entire Agreement . This Agreement, including the agreements referred to herein (which are deemed incorporated by reference herein) constitute the entire and only agreement and understanding between the parties governing the terms and conditions of employment of the Employee with the Company and this Agreement supersedes and cancels any and all previous contracts, arrangements or understandings with governing the terms and conditions of the Employee’s employment by the Company. In the event of any conflict between the terms of any other agreement between the Employee and the Company entered into prior to the Effective Date, the terms of this Agreement shall control.

(i) Counterparts . This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which, taken together, constitute one and the same agreement.

EXHIBIT A

PAYMENTS SUBJECT TO SECTION 409A

1. Subject to this Exhibit A , any severance payments and benefits that may be due under the Agreement shall begin only upon the date of the Employee’s “separation from service” (determined as set forth below) which occurs on or after the termination of the Employee’s employment. The following rules shall apply with respect to distribution of the severance payments and benefits, if any, to be provided to the Employee under the Agreement, as applicable:

(a) It is intended that each installment of the severance payments and benefits under the Agreement provided under shall be treated as a separate “payment” for purposes of Section 409A. Neither the Company nor the Employee shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A.

(b) If, as of the date of the Employee’s “separation from service” from the Company, the Employee is not a “specified employee” (within the meaning of Section 409A), then each installment of the severance payments or benefits shall be made on the dates and terms set forth in the Agreement.

(c) If, as of the date of the Employee’s “separation from service” from the Company, the Employee is a “specified employee” (within the meaning of Section 409A), then:

(i) Each installment of the severance payments and benefits due under the Agreement that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when the Employee’s separation from service occurs, be paid within the short-term deferral period (as defined under Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and shall be paid at the time set forth in the Agreement; and

(ii) Each installment of the severance payments and benefits due under the Agreement that is not described in this Exhibit A , Section 1(c)(i) and that would, absent this subsection, be paid within the six-month period following the Employee’s “separation from service” from the Company shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, the Employee’s death), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following the Employee’s separation from service and any subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment of payments and benefits if and to the maximum extent that that such installment is deemed to be paid under a

separation pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation from service). Any installments that qualify for the exception under Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of the Employee’s second taxable year following the taxable year in which the separation from service occurs.

2. The determination of whether and when the Employee’s separation from service from the Company has occurred shall be made and in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h). Solely for purposes of this Exhibit A , Section 2, “Company” shall include all persons with whom the Company would be considered a single employer under Section 414(b) and 414(c) of the Code.

3. The Company makes no representation or warranty and shall have no liability to the Employee or to any other person if any of the provisions of the Agreement (including this Exhibit) are determined to constitute deferred compensation subject to Section 409A but that do not satisfy an exemption from, or the conditions of, that section.
