Overview:

The accompanying unaudited condensed consolidated financial statements of BioDelivery Sciences International, Inc., a Delaware corporation, together with its wholly-owned subsidiaries, Arius Pharmaceuticals, Inc., a Delaware corporation (“Arius One”), and Arius Two, Inc., a Delaware corporation (“Arius Two”), and its majority-owned, inactive subsidiary, Bioral Nutrient Delivery, LLC, a Delaware limited liability company (“BND”, together with Arius One and Arius Two, collectively, the “Company” or “we”, “us” or similar terminology) have been prepared by the Company without audit. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows at June 30, 2013, and for all periods presented, have been made. All intercompany accounts and transactions have been eliminated.

Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the Securities and Exchange Commission (“SEC”) rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2012, which are included in the Company’s 2012 Annual Report on Form 10-K, filed with the SEC on March 18, 2013 (the “2012 Annual Report”). The accompanying condensed consolidated balance sheet at December 31, 2012 has been derived from the audited financial statements at that date, but does not include all information and notes required by GAAP for complete financial statements.

The Company is a specialty pharmaceutical company that is leveraging its novel and proprietary patented drug delivery technologies to develop and commercialize, either on its own or in partnerships with third parties, new applications of proven therapeutics. The Company is focusing on developing products to meet unmet patient needs in the areas of pain management and addiction.

The Company’s pain franchise currently consists of three products, two of which utilize the patented BioErodible MucoAdhesive (“BEMA”) drug delivery technology, a thin film applied to the inner lining of the cheek. ONSOLIS (fentanyl buccal soluble film) is approved in the U.S., Canada, E.U. (where it is marketed as BREAKYL) and Taiwan (where it is marketed as PAINKYL™), for the management of breakthrough pain in opioid tolerant, adult patients with cancer. The commercial rights to ONSOLIS are licensed to Meda AB (“Meda”) for all territories worldwide except for Taiwan (licensed to and TTY Biopharm Co. Ltd. (“TTY”)) and South Korea (licensed to Kunwha Pharmaceutical Co., Ltd. (“Kunwha”)). The Company’s second pain product using the BEMA technology, BEMA Buprenorphine, is in Phase 3 clinical trials for the treatment of moderate to severe chronic pain and is licensed on a worldwide basis to Endo Health Solutions, Inc. (“Endo”). The Company’s third pain product in development is Clonidine Topical Gel for the treatment of painful diabetic neuropathy, which was licensed from Arcion Therapeutics, Inc. (“Arcion”) in March 2013. Additionally, in July 2013, the Company filed a New Drug Application for BUNAVAIL (buprenorphine naloxone buccal film), a high dose formulation of buprenorphine in combination with naloxone for the maintenance treatment of opioid dependence.

The results of operations for the six month period ended June 30, 2013 are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year. Readers of this Quarterly Report are strongly encouraged to review the risk factors relating to the Company which are set forth in the 2012 Annual Report.

Fair value of financial assets and liabilities:

The Company measures the fair value of financial assets and liabilities in accordance with GAAP which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.

GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. GAAP also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. GAAP describes three levels of inputs that may be used to measure fair value:

Level 1 – quoted prices in active markets for identical assets or liabilities

Level 2 – quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 – inputs that are unobservable (for example cash flow modeling inputs based on assumptions)

The following table summarizes assets and liabilities measured at fair value on a recurring basis at June 30, 2013 and December 31, 2012, respectively:

The table below provides a reconciliation of the beginning and ending balances for the assets and liabilities measured at fair value using observable inputs (Level 2). The table reflects net gains and losses for all financial assets and liabilities categorized as Level 2 as of June 30, 2013 and December 31, 2012.

Since inception, the Company has financed its operations principally from the sale of equity securities, proceeds from short-term borrowings or convertible notes, funded research arrangements and revenue generated as a result of its agreements with Meda regarding ONSOLIS^® and Endo regarding BEMA^® Buprenorphine. The Company intends to finance its research and development and commercialization efforts and its working capital needs from existing cash, royalty revenue, new sources of financing, existing and new licensing and commercial partnership agreements and, potentially, through the exercise of outstanding Common Stock options and warrants to purchase Common Stock.

Significant new operating sources during the six months ended June 30, 2013 consisted of:

On July 5, 2013, the Company, together with Arius One and Arius Two, entered into a $20 million secured loan facility pursuant to a Credit and Security Agreement (the “Credit Agreement”) with MidCap Financial SBIC, LP, as agent and lender (“MidCap”). The Company received net proceeds in the aggregate amount of $19.9 million and will use the loan proceeds for general corporate purposes or other activities permitted under the Credit Agreement. See Note 12.

At June 30, 2013, the Company had cash and cash equivalents of approximately $37.4 million. The Company used $25.8 million of cash from operations during the six months ended June 30, 2013. As of June 30, 2013, the Company had stockholders’ equity of $27.1 million, versus $49.8 million at December 31, 2012. The Company’s existing cash (after giving effect to the proceeds of the loan from MidCap), supplemented with other expected cash inflows from milestones, royalties and the aforementioned loan, is anticipated by management to be sufficient to fully fund the Company’s operations through the fourth quarter of 2014 at the planned level of expenditures. Certain planned expenditures are discretionary and could be deferred if the Company is required to do so to fund critical operations.

Accordingly, additional capital will be required to support commercialization activities for BUNAVAIL™, clinical development programs for BEMA^® Buprenorphine (the scale of which is being governed in large part by the requirements of the Company’s agreement with Endo), the reformulation project for and anticipated commercial relaunch of ONSOLIS^®, planned development of the Company’s Clonidine Topical Gel product for painful diabetic neuropathy and general working capital. Based on product development timelines and agreements with the Company’s development partners, the ability to scale up or reduce personnel and associated costs are factors considered throughout the product development life cycle. Available resources may be consumed more rapidly than currently anticipated, resulting in the need for additional funding.

In August 2006 and September 2007, the Company entered into certain agreements with Meda to develop and commercialize the ONSOLIS^® product, a drug treatment for breakthrough cancer pain delivered through the BEMA^® technology. The aforementioned agreements relate to the United States, Mexico and Canada (such agreements, the “Meda U.S. Agreements”) and to certain countries in Europe (such agreements, the “Meda EU Agreements”, together with Meda U.S. Agreements, the “Meda Agreements”). They carry license terms that commence on the date of first commercial sale in each respective territory and end on the earlier of the entrance of a generic product to the market or upon expiration of the patents, which begin to expire in January 2017.

The Company has assessed these arrangements and their deliverables to determine if such deliverables are considered separate units of accounting at the inception or upon delivery of the items required in the arrangements. The assessment requires subjective analysis and requires management to make estimates and assumptions about whether deliverables within multiple-element arrangements are separable and, if so, to determine the fair value to be allocated to each unit of accounting.

The Company determined that upon inception of both the U.S. and EU Meda arrangements all deliverables are to be considered one combined unit of accounting since the fair value of the undelivered license was not determinable and the research and development efforts provided do not have stand-alone value apart from the license. As such, all cash payments from Meda that were related to these deliverables were recorded as deferred revenue. All cash payments from Meda for upfront and milestone payments and research and development services provided are nonrefundable. Upon commencement of the license term (date of first commercial sale in each territory), the license and certain deliverables associated with research and development services were deliverable to Meda. The first commercial sale in the U.S. occurred in October 2009. As a result, $59.7 million of the aggregate milestones and services revenue was recognized as revenue. The first commercial sale in a European country occurred in October 2012. As a result, $17.5 million was recognized as revenue, which included $5.0 million in milestones received during the year ended December 31, 2012. At June 30, 2013, there was remaining deferred revenue of $1.4 million which is related to the Meda research and development services. The Company has estimated the amount of time (based on expected man-days) and associated dollars (based on comparable services provided by outside third parties), as further noted below. As time progresses, the Company will continue to estimate the time required for ongoing obligations, and adjust the remaining deferred revenue accordingly on a quarterly basis.

In connection with delivery of the license to Meda, the Company has determined that each of the undelivered obligations have stand-alone value to Meda as these post-commercialization services encompass additional clinical trials on different patient groups but do not require further product development by the Company. These services and product supply obligations, if needed, can be provided by third-party providers available to Meda. Further, the Company obtained third-party evidence of fair value for the non-cancer and

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENT

FOR THE SIX MONTHS ENDED JUNE 30, 2013 AND 2012

(Unaudited)

other research and development services and other service obligations, based on hourly rates billed by unrelated third-party providers for similar services contracted by the Company. The Company also obtained third-party evidence of fair value of the product supply deliverable based on the outsourced contract manufacturing cost charged to the Company from the third-party supplier of the product.

The arrangements do not contain any general rights of return. Therefore, the remaining deliverables to the arrangements will be accounted for as three separate units of accounting to include: (1) product supply, (2) research and development services for the non-cancer indication and further research and development of the first indication of the ONSOLIS^® product and (3) the combined requirements related to the remaining other service-related obligations due to Meda to include participation in committees and certain other specified services. The remaining portion of the upfront payments of approximately $1.31 million (under the Meda U.S. Agreements) and $0.06 million (under the Meda EU Agreements) attributed to these other service-related obligations will be recognized as revenue as services are provided through expiration of the license terms.

The Company has determined that it is acting as a principal under the Meda Agreements and, as such, will record product supply revenue, research and development services revenue and other services revenue amounts on a gross basis in the Company’s consolidated financial statements.

The Company earns royalties based on a percentage of net sales revenue of the ONSOLIS^® product. Product royalty revenues are computed on a quarterly basis when revenues are fixed or determinable, collectability is reasonably assured and all other revenue recognition criteria are met. The Company earned $0.9 million and $0 in product royalty revenue for the six months ended June 30, 2013 and 2012, respectively. The Company has incurred cost of product royalties of approximately $1.1 million and $0.8 million for the six months ended June 30, 2013 and 2012, respectively, which included minimum royalty expenses that the Company is obligated to pay CDC IV, LLC (“CDC”) and NB Athyrium LLC (“Athyrium”) regardless of actual sales.

On March 12, 2012, the Company announced the postponement of the U.S. re-launch of ONSOLIS^® until the product formulation could be modified to address two appearance issues raised by the U.S. Food and Drug Administration (“FDA”) following an inspection of the Aveva manufacturing facility where ONSOLIS^® is produced. The FDA requested that the Company identify, characterize and address the formation of microscopic crystals and a slight fading of the color during the 24-month shelf life of the product. While these changes do not affect the product’s underlying integrity or safety, the FDA believes that the fading of the color in particular may potentially confuse patients, necessitating a modification of the product and product specifications before additional product can be manufactured and distributed. Therefore, the U.S. re-launch and additional manufacturing of ONSOLIS^® has been postponed until such product appearance issues have been resolved.

The crystal and fading issues for ONSOLIS^® were presented to the FDA at a favorable meeting in December 2012. A data generation plan to support the approval of a new formulation that resolved both issues was submitted to FDA in March 2013 and followed by initiation of manufacturing in second quarter. Submission of initial stability results for the new formulation is expected early in 2014 with approval by mid-year and re-launch of ONSOLIS^® in the second half of 2014.

On May 21, 2012, the Company announced receipt of a pre-launch milestone payment of $2.5 million from Meda in conjunction with the first country registration and pricing approval for BREAKYL™ (tradename for ONSOLIS^® in the EU). A final milestone payment related to the EU of $2.5 million was paid at the time of commercial launch, which occurred in October 2012. BREAKYL™ is commercialized in the EU by Meda.

On September 13, 2012, the Company executed a Manufacturing, Supply, and License Agreement, effective April 26, 2012, with LTS Lohmann Therapie-Systeme AG (“LTS”), under which LTS will manufacture and supply the Company its BREAKYL™ product for distribution outside of the U.S. and Canada. The Company is required to supply BREAKYL™ product to Meda, Kunwha and TTY pursuant to its obligations under certain license and supply agreements under which Meda, Kunwha, and TTY develop and commercialize the BREAKYL™ product. In conjunction with the agreement, LTS has waived all royalties on products that they produce. This does not preclude royalties that the Company owes to LTS if the Company produces BREAKYL™ with another company.

In January 2012, the Company entered into a License and Development Agreement (the “Endo Agreement”) with Endo pursuant to which the Company granted to Endo an exclusive commercial world-wide license to develop, manufacture, market and sell the Company’s BEMA^® Buprenorphine product and to complete U.S. development of such product candidate for purposes of seeking FDA approval.

Pursuant to the Endo Agreement, Endo has obtained all rights necessary to complete the clinical and commercial development of BEMA^® Buprenorphine and to sell the product worldwide. Although Endo has obtained all such necessary rights, the Company has agreed under the Endo Agreement to be responsible for the completion of certain clinical trials regarding BEMA^® Buprenorphine (and providing clinical trial materials for such trials) necessary to submit a New Drug Application (“NDA”) to the FDA in order to obtain approval of BEMA^® Buprenorphine in the U.S., in each case pursuant to a development plan set forth in the Endo Agreement (as it may be amended pursuant to the Endo Agreement). The Company is responsible for development activities through the filing of the NDA in the U.S., while Endo is responsible for the development following the NDA submission as well as the manufacturing, distribution, marketing and sales of BEMA^® Buprenorphine on a worldwide basis. In addition, Endo is responsible for all filings required in order to obtain regulatory approval of BEMA^® Buprenorphine.

Pursuant to the Endo Agreement, the Company has received (or is expected to receive upon satisfaction of applicable conditions) the following payments (some portion(s) of which will be utilized by the Company to support its development obligations under the Endo Agreement with respect to BEMA^® Buprenorphine):

The Company has assessed its arrangement with Endo and the Company’s deliverables thereunder at inception to determine: (i) the separate units of accounting for revenue recognition purposes, (ii) which payments should be allocated to which of those units of accounting and (iii) the appropriate revenue recognition pattern or trigger for each of those payments. The assessment requires subjective analysis and requires management to make judgments, estimates and assumptions about whether deliverables within multiple-element arrangements are separable and, if so, to determine the amount of arrangement consideration to be allocated to each unit of accounting.

At the inception of the Endo arrangement and in accordance with the revenue recognition criteria under ASC Topic 605, the Company determined that the Endo Agreement is a multi-deliverable arrangement under ASC Topic 605 with three deliverables: (1) the license rights related to BEMA^® Buprenorphine, (2) services related to obtaining enhanced intellectual property rights through the issuance of a particular patent and (3) clinical development services. The Company concluded that the license delivered to Endo at the inception of the Endo Agreement has stand-alone value under ASC 605-25 because Endo obtained, at the inception of the Endo Agreement, all of the rights and knowledge necessary to fully exploit its license without the Company’s further involvement. It was also determined that there was a fourth deliverable, the provision of clinical trial material (“CTM”). The amounts involved are, however, immaterial and delivered in essentially the same time frame as the clinical development services. Accordingly, the Company has not separately accounted for the CTM deliverable, but considers it part of the clinical development services deliverable.

The initial non-refundable $30 million license fee was allocated to each of the three deliverables based upon their relative selling prices using best estimates. The analysis of the best estimate of the selling price of the deliverables was based on the income approach, the Company’s negotiations with Endo and other factors, and was further based on management’s estimates and assumptions which included consideration of how a market participant would use the license, estimated market opportunity and market share, Company’s estimates of what contract research organizations would charge for clinical development services, the costs of clinical trial materials and other factors. Also considered were entity specific assumptions regarding the results of clinical trials, the likelihood of FDA approval of the subject product and the likelihood of commercialization based in part on the Company’s prior agreements with the BEMA^® technology

Based on this analysis, $15.6 million of the up-front license fee was allocated to the license (which was estimated to have a value significantly in excess of $30 million), and $14.4 million to clinical development services (which is inclusive of the cost of CTM). Although the intellectual property component was considered a separate deliverable, no distinct amount of the up-front

payment was assigned to this deliverable because the Company determined the deliverable to be perfunctory. In April 2012, the patent being sought by the Company was granted as described further below, and in May 2012, the applicable intellectual property milestone payment of $15 million was received and recognized as revenue. The amount allocated to the license was recognized as revenue in January 2012.

The portion of the upfront license fee allocated to the clinical development services deliverable ($14.4 million) is being recognized as those services are performed. The Company estimates that such clinical development services will extend into early 2014. Based on the estimated proportion of those services performed through June 30, 2013, $5.2 million was recognized as revenue in fiscal year 2012 and $3.4 million was recognized as revenue during the first six months of 2013. As a result, $5.9 million remains deferred at June 30, 2013.

The Company analyzed the milestone payments noted above in accordance with ASC 605-28 to determine if such milestones are substantive. This determination included an analysis of the Company’s performance to achieve each milestone, the enhancement of value of the delivered items, the timing of performance related to the milestone, and the reasonability of the milestone relative to all the deliverables and payment terms. The Company concluded that each of the milestones is substantive under the guidance in ASC 605-28.

The term of the Endo Agreement shall last, on a country-by-country basis, until the later of: (i) 10 years from the date of the first commercial sale of BEMA^® Buprenorphine in a particular country or (ii) the date on which the last valid claim of the Company’s patents covering BEMA^® Buprenorphine in a particular country has expired or been invalidated. The Endo Agreement shall be subject to termination: (i) by Endo, at any time, upon a specific amount of prior written notice to the Company, (ii) by Endo and the Company upon mutual written agreement, (iii) by either party upon a material default or breach of the Endo Agreement and such default or breach is not cured within a specified timeframe, (iv) the voluntary or involuntary bankruptcy of either party or (v) by the Company if Endo does not meet certain diligence obligations outside of the United States.

On February 16, 2012, the Company announced that the U.S. Patent and Trademark Office issued a Notice of Allowance regarding its patent application (No. 13/184306), which patent will extend the exclusivity of the BEMA^® drug delivery technology for the Company’s BEMA^® Buprenorphine and BUNAVAIL^TM product candidates from 2020 to 2027. On April 17, 2012, the Company announced that this patent was granted. As a result, pursuant to the Endo Agreement, the Company received a milestone payment from Endo in the amount of $15 million in May 2012. As discussed above, this milestone had been evaluated to be a substantive milestone under ASC 605-28, and therefore was recognized as revenue when the milestone was received.

The remaining milestone payments are expected to be recognized as revenue as and if they are achieved, except that one milestone is contingently refundable for a period of time. Revenue related to that milestone is expected to be recognized as refund provisions as defined in the agreement expire. Sale threshold payments and sales-based royalties will be recognized as they accrue under the terms of the Endo Agreement.

On March 26, 2013, the Company entered into a definitive Exclusive License Agreement (the “Arcion Agreement”) with Arcion pursuant to which Arcion agreed to grant to the Company an exclusive commercial world-wide license, with rights of sublicense, under certain patent and other intellectual property rights related to in-process research and development to develop, manufacture, market, and sell gel products containing clonidine (or a derivative thereof), alone or in combination with other active ingredients, for topical administration for the treatment of painful diabetic neuropathy and other indications (the “Arcion Products”).

Pursuant to the Arcion Agreement, the Company is responsible for using commercially reasonable efforts to develop and commercialize Arcion Products, including the use of such efforts to conduct certain clinical trials within certain time frames.

Upon execution of the Arcion Agreement, the Company issued to Arcion 500,516 unregistered shares of Common Stock (having a fair market value of $2.1 million), which shares are subject to a nine month lock-up and certain limitations on sale thereafter. The issuance of such shares (delivered April 2013) was exempt from registration under the Securities Act of 1933, as amended, in reliance on Section 4(2) thereof. In addition, the Company is required to make the following payments to Arcion:

(Unaudited)

In addition, the Company shall pay Arcion $35 million in cash on initial FDA approval of an Arcion Product, unless; (i) the Company does not receive at least $70 million in FDA approval-related milestone payments from its US sublicensees (if any sublicenses are involved) with respect to the Arcion Product, in which case the Company shall pay Arcion a prorated amount between $17.5 million and $35 million based on the total amount of such milestone payments received by the Company and its affiliates from its sublicenses (if any sublicenses are involved); or (ii) the FDA requires or recommends the performance of a capsaicin challenge test as a precondition or precursor to the prescribing of the Arcion Product (as a condition of approval, a labeling requirement, or otherwise), in which case such milestone shall be reduced to $17.5 million, but the first and second sales threshold payments described above shall each be increased by $8 million.

All milestone payments due Arcion under the Arcion Agreement are payable only once each.

In addition to the milestones set forth above, the Company will pay Arcion:

The aforementioned sales royalties are subject to certain reductions, on a country-by-country and product-by-product basis, under certain agreed upon circumstances. In addition, in the event the amount due upon FDA approval of the Arcion Product in the U.S. is less than $35 million for any reason other than an FDA requirement or recommendation of a capsaicin challenge test, as described above, the Company shall pay Arcion a portion of any milestone payments received by the Company and its affiliates from their sublicensees on the basis of any events occurring in the U.S. following FDA approval but prior to (and including) first commercial sale of an Arcion Product in the U.S., and certain of the payments to Arcion referred to above shall also be subject to upward adjustment (with such upward adjustments payable in the form of cash or unregistered shares of the Company’s Common Stock, as elected solely by the Company), until such time as the sum of all such additional payments and upward adjustments (including the value of any issuances of stock, if elected by the Company) and the initial amount paid on the initial FDA approval totals $35 million.

The term of the Arcion Agreement continues, on a country-by-country and product-by-product basis, until the earlier of (i) the expiration of the royalty term for a particular Arcion Product in a particular country or (ii) the effective date of termination by either party pursuant to customary termination provisions. The royalty term for any given country is the later of (i) the first date there are no valid claims against any Arcion patent, (ii) expiration of patent exclusivity or (iii) tenth anniversary of the first commercial sale. Further, the Company may, in its sole discretion, terminate the Arcion Agreement upon certain notice to Arcion. Upon expiration of the Agreement pursuant to clause (i) above with respect to a particular Arcion Product and country, the Company and its affiliates shall have the perpetual, unrestricted, irrevocable, fully-paid, royalty-free exclusive right, with rights of sublicense, to make, have made, use, sell, offer for sale, and import such Arcion Product in such country.

In conjunction with this transaction, the March 2013 payment to Arcion of $2.1 million in unregistered Common Stock was for in-process research and development and has been recorded as research and development expense in the condensed consolidated statement of operations for the six months ended June 30, 2013.

Kunwha License Agreement

In May 2010, the Company entered into a License and Supply Agreement (the “Kunwha License Agreement”) with Kunwha to develop, manufacture, sell and distribute the Company’s BEMA^® Fentanyl product in the Republic of Korea (the “Kunwha Territory”). BEMA^® Fentanyl is marketed as ONSOLIS^® in North America. The Kunwha License Agreement is for a term beginning on May 26, 2010 until the date of expiration of the patents, or July 23, 2027, whichever is later.

Under the terms of the Kunwha License Agreement, Kunwha was granted exclusive licensing rights for BEMA^® Fentanyl in the Kunwha Territory, while the Company will retain all other licensing rights to the Licensed Product not previously granted to third parties. Kunwha paid to the Company an upfront payment of $0.3 million (net of taxes approximating $0.25 million) and will be responsible to make certain milestone payments which could aggregate up to $1.3 million (net of taxes approximating $1.1 million).

In addition, Kunwha will pay royalties to the Company based on Net Sales (as defined in the Kunwha License Agreement) and will purchase all supplies of BEMA^® Fentanyl from the Company.

Kunwha will be responsible for payment of all costs associated with BEMA^® Fentanyl in the Kunwha Territory. Kunwha and the Company will own any Improvements (as defined in the Kunwha License Agreement) made exclusively by such party with respect to BEMA^® Fentanyl and will jointly own any Improvements that are the product of collaboration.

TTY License and Supply Agreement

On October 7, 2010, the Company announced a license and supply agreement with TTY for the exclusive rights to develop and commercialize BEMA^® Fentanyl in the Republic of China, Taiwan. The agreement results in potential milestone payments to the Company of up to $1.3 million, which includes an upfront payment of $0.3 million, which was recorded as contract revenue in 2010. In addition, the Company will receive an ongoing royalty based on net sales. TTY will be responsible for the regulatory filing of BEMA^® Fentanyl in Taiwan as well as future commercialization in that territory. The term of the agreement with TTY is for the period from October 4, 2010 until the date fifteen (15) years after first commercial sale unless the agreement is extended in writing or earlier terminated as provided for in the agreement.

On November 7, 2011, the Company announced that TTY had submitted an NDA for marketing authorization of BEMA^® Fentanyl to the Taiwan Food and Drug Administration. This triggered a milestone payment to the Company of approximately $0.3 million, which was received November 2011 and recorded as contract revenue in 2011.

On July 29, 2013, the Company announced the regulatory approval of BEMA^® Fentanyl in Taiwan, where the product will be marketed under the brand name PAINKYL™. The approval in Taiwan results in a milestone payment of $0.3 million to the Company, which is expected to be received in the third quarter 2013.

Agreement with Tolmar to Purchase BEMA^® Rights

In August 2006, the Company purchased from QLT USA, Inc. (renamed TOLMAR Therapeutics, Inc. and referred to herein as “Tolmar”) all of the non-U.S. rights to the BEMA^® drug delivery technology, including all patent rights and related intellectual property and other assets. This is included in acquired product rights in the accompanying condensed consolidated balance sheet. The Company had previously licensed such rights from Tolmar. The aggregate purchase price for the non-U.S. portion of the BEMA^® technology was $3 million, consisting of $1 million in cash paid at closing and a promissory note of $2 million to be paid over time as follows: (i) $1 million by the end of first quarter 2007 (which was paid March 30, 2007) and (ii) $1 million to be paid within 30 days of regulatory approval of the first non-U.S. BEMA^® product. On June 18, 2010, in conjunction with BEMA^® approval in Canada, the Company paid $0.75 million of the $1 million to Tolmar and the remaining $0.25 million was paid in December 2011. As part of the transaction, and solely with respect to the non-U.S. portion of the former license with Tolmar, no further milestone payments or ongoing royalties will be due to Tolmar for the non-U.S. BEMA^® rights.

In September 2007, the Company purchased all North American (U.S., Canada and Mexico) assets related to the BEMA^® drug delivery technology from Tolmar for $7 million, consisting of $3 million in cash and a promissory note of $4 million, $2 million of which was paid in July 2009 following approval of ONSOLIS^® in the U.S., and $2 million of which is due within thirty (30) days of the end of the calendar quarter during which cumulative net sales of BEMA^®-based products reach $30 million. This is included in acquired product rights in the accompanying condensed consolidated balance sheet. The Company had previously licensed such rights from Tolmar. As part of the transaction, no further milestone payments or ongoing royalties will be due to Tolmar for the North American territory. To secure the Company’s obligation to pay the remaining $2 million amount when due, Tolmar was granted a security interest in the North American BEMA^® assets, subject to a license of those assets from Tolmar to us for North America that would be granted to us on the original license terms upon any exercise of rights under such security interest.

On January 5, 2012, the Company and Arius Two executed a letter agreement with Tolmar and its parent company, TOLMAR Holding, Inc., whereby the parties agreed that, if Arius Two paid Tolmar $1.05 million by February 28, 2012, Tolmar would accept such payment as satisfaction in full of the remaining $2 million outstanding under the Tolmar note (pursuant to which the Company

acquired the North American rights to the BEMA^® technology) and, upon receipt of such payment (i) the related security agreements, security interests, liens, guaranties and payment obligations with respect to such note and the assets securing its repayment would terminate, (ii) Tolmar would execute a corresponding release and (iii) neither the Company nor Arius Two will have any further payment obligations to Tolmar under the note or BEMA^® acquisition documents, except with respect to certain indemnification obligations of Arius Two. Arius Two paid the $1.05 million contemplated by the letter agreement on January 6, 2012, fully satisfying the outstanding balance of the note, and Tolmar subsequently executed its final release of the related security interests contemplated by the letter agreement. As a result, the Company now owns all rights to the BEMA^® technology on a worldwide basis.

In 2009, as part of a settlement arrangement, the Company received a warrant from Accentia Biopharmaceuticals, Inc., a related party (“Accentia”), to purchase 2 million shares of common stock of Biovest International, Inc. (“Biovest”) held by Accentia. Biovest is a majority-owned subsidiary of Accentia. During the six months ending June 30, 2013, Biovest filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code with the United States Bankruptcy Court. On July 9, 2013, the plan became effective, which canceled all outstanding common stock. As a result, the warrants had no value as of June 30, 2013 and the reduction of value is included in derivative gain (loss) in the condensed consolidated statement of operations for the three and six months ended June 30, 2013.

The Company generally does not use derivative instruments to hedge exposures to cash-flow risks or market-risks that may affect the fair values of its financial instruments. However, certain other financial instruments, such as warrants and embedded conversion features that are indexed to the Company’s Common Stock, are classified as liabilities when either: (a) the holder possesses rights to net-cash settlement or (b) physical or net-share settlement is not within the control of the Company. In such instances, net-cash settlement is assumed for financial accounting and reporting, even when the terms of the underlying contracts do not provide for net-cash settlement. Such financial instruments are initially recorded at fair value estimated on the settlement date using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate, and then adjusted to fair value at the close of each reporting period.

Stock-based compensation:

During the six months ended June 30, 2013, a total of 116,242 options to purchase Common Stock with an aggregate fair market value of approximately $0.3 million were granted to Company employees. The options granted have a term of 10 years from the grant date. The options vest ratably over a three year period. The fair value of each option is amortized as compensation expense evenly through the vesting period. The fair value of each option award is estimated on the grant date using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatilities are based on implied volatilities from historical volatility of the Common Stock, and other factors estimated over the expected term of the options. The expected term of options granted is derived using the “simplified method” which computes expected term as the average of the sum of the vesting term plus contract term. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term. The weighted average for key assumptions used in determining the fair value of options granted during the six months ended June 30, 2013 follows:

As of June 30, 2013, there was approximately $8.5 million of unrecognized compensation cost related to unvested share-based compensation awards granted. These costs will be expensed through 2019.

Warrants:

The Company has granted warrants to purchase shares of Common Stock. Warrants may be granted to affiliates in connection with certain agreements. Warrants outstanding at June 30, 2013, all of which are exercisable are as follows:

Midcap:

The Company issued warrants to purchase 357,356 shares of Common Stock at a price of $4.20 in connection with a loan financing in July 2013. The warrants had a fair value of $1.5 million at the date of the grant. (See Note 12 for a description of the Midcap loan transaction). These warrants are not included in the table above.

Restricted Stock Units:

During the six months ended June 30, 2013, a total of 1,078,336 restricted stock units (“RSUs”) with a fair market value of approximately $4.5 million were granted to members of the Company’s senior management. The fair value of restricted units is determined using quoted market prices of the Common Stock and the number of shares expected to vest. These RSUs were issued under the Company’s 2011 Equity Incentive Plan, as amended, and vest in equal installments over three years. This grant was in lieu of the 2012 annual option grant typically given to senior management in order to bring the percentage ownership of our senior management in line with the senior management of companies in the Company’s peer group.

In addition, in June 2013, the Company issued 3,125 new hire RSUs with a fair value of $0.01 million to a board member, which vested immediately.

Preferred Stock

The Company had authorized five million “blank check” shares of $.001 par value convertible preferred stock. At June 30, 2013, 2,709,300 shares of Series A Preferred were outstanding.

The following table reconciles the numerators and denominators of the basic and diluted loss per share computations.

Basic earnings per common share is calculated using the weighted average shares of Common Stock outstanding during the period. In addition to the weighted average shares of Common Stock outstanding, common equivalent shares from stock options and warrants using the treasury stock method, are included in the diluted per share calculations unless the effect of inclusion would be antidilutive. During the six months ended June 30, 2013 and 2012, outstanding stock options and warrants of 6,216,978 and 3,047,964, respectively, were not included in the computation of diluted earnings per common share, because to do so would have had an antidilutive effect because the outstanding exercise prices were greater than the average market price of the common shares during the relevant periods.

The following is the total outstanding options and warrants for the six months ended June 30, 2013 and 2012, respectively.

In March 2012, the Company announced that the New Jersey Federal Court granted a stay of further litigation in the patent infringement lawsuit previously filed by MonoSol Rx, LLC (“MonoSol”) against the Company and its ONSOLIS^® commercial partners. The court ordered that the case would be stayed pending resolution by the United States Patent and Trademark Office (“USPTO”) of reexamination proceedings and follows the recent rejection by the USPTO of all claims in all three patents asserted by MonoSol against the Company and its commercial partners for ONSOLIS^®.

In July 2012, a Reexamination Certificate for MonoSol’s ‘292 Patent in its amended form was issued by the USPTO. The USPTO also issued a second Office Action closing prosecution on MonoSol’s ‘588 Patent. The Action rejects all claims as anticipated or obvious for a second time. It also rejects the amended claims proposed by MonoSol as unclear and lacking support. In August 2012, a Reexamination Certificate for MonoSol’s ‘891 Patent in its amended form was issued.

On January 23, 2013, the USPTO issued a Right of Appeal Notice, rejecting all claims of the ‘588 Patent and closing reexamination proceedings. This action confirms that all claims of this patent are also invalid, but unlike ‘292 and ‘891, the USPTO has not found that any amended or narrower claims should be granted. On February 22, 2013, MonoSol filed both a Notice of Appeal to the Board of Patent Appeals and Interferences and a Request for Continuing Examination of the ‘588 Patent. Subsequently, on July 3, 2013, the USPTO denied MonoSol’s February 22, 2013 Request to Continue Examination.

Inter partes reviews, a new USPTO process to review the patentability of one or more claims of patents, was enacted in September, 2012. As such, on June 12, 2013, despite the Company’s previously noted success in the prior ex parte reexaminations for the “292” and “891” patents, the Company availed themselves of this new process and filed requests for inter partes reviews on the narrowed yet reexamined patents, the ‘292C1 and ‘891C1 Patents, to challenge their validity and continue to strengthen the Company’s position. This inter partes review process allows the Company to actively participate in the reviews and address any of MonoSol’s arguments and representations made during the review process, which heightens the Company’s ability to invalidate these patents. The Company is awaiting the USPTO’s decision as to whether they will accept the Company’s requests for these reviews. (See Part II, Item 1, Legal Proceedings).

Midcap:

On July 5, 2013, the Company, Arius One and Arius Two (the “Borrowers”) entered into a $20 million secured loan facility (the “Loan Transaction” and such loan, the “Loan”) with MidCap as agent and lender pursuant to the terms and conditions of the Credit Agreement. The Company received net proceeds in the aggregate amount of $19.9 million and will use the Loan proceeds for general corporate purposes or other activities of the Borrower permitted under the Credit Agreement.

In addition, pursuant to the Loan Transaction, the Company issued to MidCap a warrant (the “MidCap Warrant”) to purchase 357,356 unregistered shares of Common Stock, which warrant has an exercise price of $4.20 per share, the 20-day volume-weighted average share price of the Common Stock prior to the closing of the Loan. The MidCap Warrant is exercisable for a term of five (5) years and contains cashless exercise provisions and customary, stock-based anti-dilution protection provisions.

The Loan has a term of 36 months with interest only payments for the first 6 months. The interest rate is 8.45% plus a LIBOR floor of 0.5%. Upon execution of the Credit Agreement, the Company paid to MidCap a closing fee of 0.5% of the aggregate Loan amount. Upon repayment in full of the Loan, the Company is obligated to make a final payment fee equal to 3.5% of the aggregate Loan amount. In addition, the Company may prepay all or any portion of the Loan at any time subject to a prepayment premium of: (i) 5% of the Loan amount prepaid in the first year of the Loan and (ii) 3% of the Loan amount prepaid in each year thereafter. In addition, if the Company receives the second of two anticipated database lock milestone payments (the “Database Lock Payments”) from Endo in connection with the Endo Agreement, the Company may prepay 50% of the principal amount of the Loan then outstanding and, concurrently and at the Company’s election, either: (i) pay to MidCap a cash prepayment fee of 2% of the principal amount of the Loan and all obligations thereunder outstanding as of the date of prepayment or (ii) issue to MidCap a warrant (in a form substantially similar to the MidCap Warrant) to purchase shares of Common Stock equal to 2.0% of the prepayment amount, with the number of shares being calculated using the Black-Scholes pricing model.

The obligations of the Borrowers under the Credit Agreement are secured by a first priority lien in favor of MidCap on substantially all of the Borrowers’ existing and after-acquired assets, but excluding certain of the Borrowers’ intellectual property and general intangible assets of the Borrowers (but not any proceeds thereof). The obligations of the Company under the Loan Agreement are also secured by a first priority lien on the equity interests held by the Company in Arius One, Arius Two and BND. The Borrowers entered into customary pledge and intellectual property security agreements to evidence the security interest in favor of MidCap.

Under the Credit Agreement, the Borrowers are subject to affirmative covenants which are customary for financings of this type, including the obligations of the Borrowers to: (i) maintain good standing and governmental authorizations, (ii) provide certain information and notices to MidCap, (iii) deliver monthly and annual financial statements to MidCap, (iv) maintain insurance, (v) discharge all taxes, (vi) protect their intellectual property and (vii) generally protect the collateral granted to MidCap.

The Borrowers are also subject to negative covenants customary for financings of this type, including that they may not: (i) enter into a merger or consolidation or certain change of control events, (ii) incur liens on the collateral, (iii) incur additional indebtedness, (iii) dispose of any property, (iv) amend material agreements or organizational documents, (v) change their jurisdictions of organization or their organizational structures or types, (vi) declare or pay dividends (other than dividends payable solely in Common Stock), (vii) make certain investments or acquisitions, or (viii) enter into certain transactions with affiliates, in each case subject to certain exceptions provided for in the Credit Agreement, including exceptions that allow the Borrowers to acquire additional products and to enter into licenses and similar agreements provided certain conditions are met.

The Credit Agreement provides that events of default include: (i) failure to make payment of principal or interest on the Loan when required, (ii) failure to perform obligations under the Credit Agreement and related documents, (iii) defaults in other indebtedness and breaches of material agreements of the Borrowers, (iv) if any Borrower shall generally not pay its debts as such debts become due and similar insolvency matters, (v) material adverse changes to the Borrowers (subject to a 10-day notice and cure period), (vi) if the Company ceases to be a publicly-listed and reporting company, (vii) failure to receive the Database Lock Payments by June 30, 2014, and (viii) certain other events, including certain adverse actions taken by the Food and Drug Administration or other governmental authorities. Upon an event of default, the Borrower’s obligations under the Credit Agreement may, or in the event of insolvency or bankruptcy will automatically, be accelerated. Upon the occurrence of any event of default, the Borrower’s obligations under the Credit Agreement will bear interest at a rate equal to the lesser of: (i) 4% above the rate of interest applicable to such obligations immediately prior to the occurrence of the event of default and (ii) the maximum rate allowable under law.

TTY Biopharm:

On July 29, 2013, the Company announced the regulatory approval of ONSOLIS^® in Taiwan for the management of breakthrough cancer pain in opioid tolerant, adult patients with cancer.

In Taiwan, the Company has licensed the commercialization rights to TTY, where the product will be marketed under the brand name PAINKYL™. TTY will be responsible for the cost of future product commercialization in Taiwan and expects to launch PAINKYL™ following receipt of reimbursement pricing from the Taiwanese national healthcare system. The approval in Taiwan results in a milestone payment of $0.3 million to the Company, which is expected to be received in the third quarter 2013. Upon launch, the Company will receive a royalty on net sales.

The following discussion and analysis should be read in conjunction with the Condensed Consolidated Financial Statements and Notes thereto included elsewhere in this Quarterly Report. This discussion contains certain forward-looking statements that involve risks and uncertainties. The Company’s actual results and the timing of certain events could differ materially from those discussed in these forward-looking statements as a result of certain factors, including, but not limited to, those set forth herein and elsewhere in this Quarterly Report and in the Company’s other filings with the Securities and Exchange Commission (the “SEC”). See “Cautionary Note Regarding Forward Looking Statements” below.

For the three months ended June 30, 2013 compared to the three months ended June 30, 2012

Product Royalty Revenues. We recognized $0.9 million in product royalty revenue during the three months ended June 30, 2013 under our license agreement with Meda. No such revenue was reported in the corresponding period of 2012. The product royalty revenues can be attributed to the commercial launch of BREAKYL™ in the EU in October 2012.

Contract Revenues. We recognized $1.9 million and $16.3 million in contract revenue during the three months ended June 30, 2013 and 2012, respectively, under the Endo Agreement. The 2012 amount included a $15 million payment received from Endo in May 2012 for a milestone associated with the granting of a certain patent. We also recognized $0.05 million during both of the three months ended June 30, 2013 and 2012, in contract revenue related to previously deferred revenue under our license agreement with Meda.

Cost of Product Royalties. We recognized $0.7 million and $0.4 million in cost of product royalties during the three months ended June 30, 2013 and 2012, respectively. Both periods include minimum quarterly payments to CDC and the 2013 period also includes cost of product royalties in support of the EU commercial launch of BREAKYL™.

Research and Development Expenses. During the three months ended June 30, 2013 and 2012, research and development expenses totaled $12.8 million and $6.5 million, respectively. The increase in research and development expenses can be attributed to the two pivotal pain and one safety trial underway pursuant to the Endo Agreement for our Buprenorphine chronic pain program. Also contributing to the 2013 increase was the completion of the BUNAVAIL^™ program for the treatment of opioid dependence and compilation of the NDA, as well as $2.1 million of in-process research and development (paid in Common Stock) associated with the aforementioned license agreement with Arcion. Our scientific staff continues to work toward development and application of our BEMA^® delivery technology, particularly with respect to ONSOLIS^®, BEMA^® Buprenorphine for chronic pain and BUNAVAIL^™ for the treatment of opioid dependence. Funding of this research in 2013 and 2012 was obtained through contract revenue, deferred license revenue, a private placement stock offering, exercise of options by employees and directors and sales of securities. Research and development expenses generally include compensation for scientific personnel, research supplies, facility rent, manufacturing equipment depreciation and a portion of overhead operating expenses and other costs directly related to the development and application of the BEMA^® drug delivery technologies.

General and Administrative Expenses, net. During the three months ended June 30, 2013 and 2012, general and administrative expenses totaled $3.1 million and $2.2 million, respectively. General and administrative costs include legal, accounting and management wages, legal and professional fees, office supplies, travel costs, compensation costs, consulting fees and business development costs. The increase in general and administration expenses can be primarily attributed to stock compensation expense, which was $0.8 million and $0.2 million for the three months ended June 30, 2013 and 2012, respectively.

Interest Income. During the three months ended June 30, 2013 and 2012 we had interest income of $0.1 million and $0.06 million, respectively.

Derivative gain (loss). Our derivative liability consists of free standing warrants measured at their fair market value, using the Black-Scholes method. During the three months ended June 30, 2013, our stock price decreased. This is the largest component of the Black-Scholes change. As a result, our warrant liability also decreased, resulting in a $0.4 million gain. This gain was offset by a $0.03 million loss from 2 million shares of Biovest related party warrants that we wrote off. During the three months ended June 30, 2012, our stock price increased. Therefore, our derivative liability increased, resulting in a $3.2 million loss. Also included in the 2012 loss was a $0.3 million loss on the value of our former Biovest warrant.

For the six months ended June 30, 2013 compared to the six months ended June 30, 2012

Product Royalty Revenues. We recognized $0.9 million in product royalty revenue during the six months ended June 30, 2013 under our license agreement with Meda. No such revenue was reported during the corresponding period of 2012. The increase in product royalty revenues can be attributed to the commercial launch of BREAKYL™ in the EU in October 2012.

Research Revenues. We recognized $0.01 million of revenue related to a research and development agreement with Meda during the six months ended June 30, 2012. There was no research revenue during the six months ended June 30, 2013.

Table of Contents

Contract Revenues. We recognized $3.4 million and $32.8 million in contract revenue during the six months ended June 30, 2013 and 2012, respectively, under the Endo Agreement. The 2012 amount includes $15.6 million of the $30 million up-front license fee from Endo received in January 2012 ($14.4 million was recorded as deferred contract revenue), $15 million received from Endo in May 2012 for a milestone associated with the granting of a certain patent and $2.1 million in previously deferred contract revenue. We also recognized $0.1 million during both of the six months ended June 30, 2013 and 2012, in contract revenue related to previously deferred revenue under our license agreement with Meda.

Cost of Product Royalties. We recognized $1.1 million and $0.8 million in cost of product royalties during the six months ended June 30, 2013 and 2012, respectively. Both periods include minimum quarterly payments to CDC and the 2013 period also includes cost of product royalties in support of the EU commercial launch of BREAKYL™.

Research and Development Expenses. During the six months ended June 30, 2013 and 2012, research and development expenses totaled $24.8 million and $11.3 million, respectively. The increase in research and development expenses can be attributed to the two pivotal pain and one safety trials underway pursuant to the Endo Agreement for our Buprenorphine chronic pain program. Also contributing to the 2013 increase was the completion of the BUNAVAIL^™ program for the treatment of opioid dependence and compilation of the NDA, as well as $2.1 million of in-process research and development (paid in Common Stock) associated with the aforementioned license agreement with Arcion. Our scientific staff continues to work toward development and application of our BEMA^® delivery technology, particularly with respect to ONSOLIS^®, BEMA^® Buprenorphine for chronic pain and BUNAVAIL^™ for the treatment of opioid dependence. Funding of this research in 2013 and 2012 was obtained through contract revenue, deferred license revenue, a private placement stock offering, exercise of options by employees and directors and sales of securities. Research and development expenses generally include compensation for scientific personnel, research supplies, facility rent, manufacturing equipment depreciation and a portion of overhead operating expenses and other costs directly related to the development and application of the BEMA^® drug delivery technologies.

General and Administrative Expenses, net. During the six months ended June 30, 2013 and 2012, general and administrative expenses totaled $6 million and $5.1 million, respectively. General and administrative costs include legal, accounting and management wages, legal and professional fees, office supplies, travel costs, compensation costs, consulting fees and business development costs. The increase in general and administration expenses can be primarily attributed to stock compensation expense, which was $1.4 million and $0.7 million for the six months ended June 30, 2013 and 2012, respectively.

Interest Income. During the six months ended June 30, 2013 and 2012 we had interest income of $0.2 million and $0.1 million, respectively.

Derivative gain (loss). Our derivative liability consists of free standing warrants measured at their fair market value, using the Black-Scholes method. During the six months ended June 30, 2013, our stock price decreased. This is the largest component of the Black-Scholes change. As a result, our warrant liability also decreased, resulting in a $1.5 million gain. This gain was offset by a $0.05 million loss from 2 million shares of Biovest related party warrants that we wrote off. During the six months ended June 30, 2012, our stock price increased. Therefore, our derivative liability increased, resulting in a $5.4 million loss. This loss was offset by a $0.01 million gain on the value of our former Biovest warrant.

Liquidity and Capital Resources

Since inception, we have financed our operations principally from the sale of equity securities, proceeds from short-term borrowings or convertible notes, funded research arrangements, revenue generated as a result of our worldwide license and development agreement with Meda regarding ONSOLIS^® and revenue generated as a result of our January 2012 agreement with Endo regarding our BEMA^® Buprenorphine product candidate. We intend to finance our research and development, commercialization efforts and our working capital needs from existing cash, royalty revenue, new sources of financing, licensing and commercial partnership agreements and, potentially, through the exercise of outstanding Common Stock options and warrants to purchase Common Stock.

At June 30, 2013, we had cash and cash equivalents of approximately $37.4 million. We used $25.8 million of cash from operations during the six months ended June 30, 2013. As of June 30, 2013, we had stockholders’ equity of $27.1 million versus $49.8 million at December 31, 2012. Our existing cash as of the date of this Report (including proceeds of our $20 million loan transaction in July 2013), together with other expected cash inflows from other milestones and royalties, is anticipated by management to be sufficient to fully fund our planned level of operations through the fourth quarter of 2014.

Additional capital may be required to support commercialization activities for BUNAVAIL^TM, clinical development programs for BEMA^® Buprenorphine (the scale of which is being governed in large part by the requirements of our agreement with Endo), the reformulation project for and anticipated commercial relaunch of ONSOLIS^®, planned development of Clonidine Topical Gel produced for painful diabetic neuropathy and general working capital. Based on product development timelines and agreements with our development partners, the ability to scale up or reduce personnel and associated costs are factors considered throughout the product development life cycle. Available resources may be consumed more rapidly than currently anticipated, resulting in the need for additional funding.

Also, product development timelines and agreements with our development partners, the ability to scale up or reduce personnel and associated costs are factors considered throughout the product development life cycle. Available resources may be consumed more rapidly than currently anticipated, resulting in the need for additional funding.

Accordingly, we anticipate that we will be required to raise additional capital, which may be available to us through a variety of sources, including:

Readers are cautioned that additional funding, capital or loans (including, without limitation, milestone or other payments from potential commercialization agreements) may be unavailable on favorable terms, if at all. If adequate funds are not available, we may be required to significantly reduce or refocus our operations or to obtain funds through arrangements that may require us to relinquish rights to certain technologies and drug formulations or potential markets, any of which could have a material adverse effect on us, our financial condition and our results of operations in 2013 and beyond. To the extent that additional capital is raised through the sale of equity or convertible debt securities or exercise of warrants and options, the issuance of such securities would result in ownership dilution to existing stockholders.

If we are unable to attract additional funds on commercially acceptable terms, it may adversely affect our ability to achieve our development and commercialization goals, which could have a material and adverse effect on our business, results of operations and financial condition.

Contractual Obligations and Commercial Commitments

Our contractual obligations as of June 30, 2013 are as follows:

On July 5, 2013, we entered into a $20 million secured loan facility with MidCap Financial SBIC, LP. The Loan has a term of 36 months with interest only payments for the first 6 months.

Critical Accounting Policies

Valuation of Goodwill and Intangible Assets

Our intangible assets include goodwill, product rights, and licenses, all of which are accounted for based on GAAP related to Goodwill and Other Intangible Assets. Accordingly, goodwill is not amortized but is tested annually in December for impairment or more frequently if events or changes in circumstances indicate that the asset might be impaired. Intangible assets with limited useful lives are amortized using the straight-line method over their estimated period of benefit, ranging from eleven to thirteen years. Our carrying value of goodwill at June 30, 2013 was $2.715 million.

We amortize intangibles with limited useful lives based on their expected useful lives and look to a number of factors for such estimations, including the longevity of our license agreements or the underlying patents. Our carrying value of other amortizing intangible assets at June 30, 2013 was $5.7 million, net of accumulated amortization of $5.3 million. We begin amortizing capitalized intangibles on their date of acquisition.
