NOTES TO CONDENSED FINANCIAL STATEMENTS

JUNE 30, 2012

(Unaudited)

1. Reverse Merger Transaction and Accounting

Reverse Merger Transaction

On September 21, 2009, QuikByte Software, Inc., a Colorado corporation and shell company, or QuikByte, acquired Sorrento Therapeutics, Inc., a privately held Delaware corporation, or STI, in a reverse merger, or the Merger. Pursuant to the Merger, all of the issued and outstanding shares of STI common stock were converted, at an exchange ratio of 25.48433-for-1, into an aggregate of 169,375,807 shares of QuikByte common stock and STI became a wholly owned subsidiary of QuikByte. The holders of QuikByte’s common stock as of immediately prior to the Merger held an aggregate of 55,708,320 shares of QuikByte’s common stock, which consisted of: (i) 11,073,946 shares of common stock outstanding as of September 17, 2009, and (ii) 44,634,374 shares of common stock issued on September 18, 2009 in connection with a $2.0 million private placement. The accompanying financial statements share and per share information has been retroactively adjusted to reflect the exchange ratio in the Merger.

STI was originally incorporated as San Diego Antibody Company in California in 2006 and was renamed Sorrento Therapeutics, Inc. and reincorporated in Delaware in 2009, prior to the Merger. QuikByte was originally incorporated in Colorado in 1989. Following the Merger, on December 4, 2009, QuikByte reincorporated under the laws of the State of Delaware, or the Reincorporation. Immediately following the Reincorporation, on December 4, 2009, STI merged with and into QuikByte, the separate corporate existence of STI ceased and QuikByte continued as the surviving corporation, or the Roll-Up Merger. Pursuant to the certificate of merger filed in connection with the Roll-Up Merger, QuikByte’s name was changed from QuikByte Software, Inc. to Sorrento Therapeutics, Inc., or the Company.

Reverse Merger Accounting

Immediately following the consummation of the Merger, the: (i) former security holders of STI common stock had an approximate 75% voting interest in QuikByte and the QuikByte stockholders retained an approximate 25% voting interest, (ii) former executive management team of STI remained as the primary continuing executive management team for the Company, and (iii) Company’s ongoing operations consisted solely of the ongoing operations of STI. Based primarily on these factors, the Merger was accounted for as a reverse merger and a recapitalization in accordance with generally accepted accounting principles in the U.S., or GAAP. As a result, these financial statements reflect the: (i) historical results of STI prior to the Merger, (ii) combined results of the Company following the Merger, and (iii) acquired assets and liabilities at their historical cost, which approximates their fair value at the Merger date. In connection with the Merger, the Company received cash of $104,860, other current assets of $20,150 and assumed accounts payable of $24,624.

2. Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations and Basis of Presentation

The Company is a biopharmaceutical company focused on the discovery, development and commercialization of novel and proprietary biotherapeutics for the treatment of a variety of disease conditions, including cancer, inflammation, metabolic and infectious diseases. The Company’s objective is to either independently or through one or more partnerships with pharmaceutical or biopharmaceutical organizations identify drug development candidates derived from the libraries.

As of June 30, 2012, the Company had devoted substantially all of its efforts to product development, raising capital and building infrastructure, and had not realized revenues from its planned principal operations. Accordingly, the Company is considered to be in the development stage.

The accompanying interim condensed financial statements have been prepared by the Company, without audit, in accordance with the instructions to Form 10-Q and, therefore, do not necessarily include all information and footnotes necessary for a fair statement of its financial position, results of operations and cash flows in accordance with GAAP. The balance sheet at December 31, 2011 is derived from the audited balance sheet at that date which is not presented herein.

In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, which are only normal and recurring, necessary for a fair statement of financial position, results of operations and cash flows. These condensed financial statements should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011. Operating results for interim periods are not necessarily indicative of operating results for the Company’s 2012 fiscal year.

Liquidity

The accompanying financial statements have been prepared on the going concern basis, which assumes that the Company will continue to operate as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. As reflected in the accompanying condensed financial statements, the Company has incurred operating losses since its inception in 2006, and as of June 30, 2012, had an accumulated deficit of $7,954,235. At June 30, 2012, the Company had working capital of $7,311,837. Management believes the Company has the ability to meet all obligations due over the course of the next twelve months.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual results may differ from these estimates ..

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. The Company minimizes its credit risk associated with cash by periodically evaluating the credit quality of its primary financial institution. The balance at times may exceed federally insured limits. The Company has not experienced any losses on such accounts.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, grants receivable, prepaid expenses and other assets, accounts payable and accrued expenses. Fair value estimates of these instruments are made at a specific point in time, based on relevant market information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. As of June 30, 2012 and December 31, 2011, the carrying amount of cash and cash equivalents, grants receivable, prepaid expenses and other assets, accounts payable and accrued liabilities are generally considered to be representative of their respective fair values because of the short-term nature of those instruments.

Grants Receivable

Grants receivable at June 30, 2012 and December 31, 2011 represent amounts due under three federal contracts with the National Institute of Allergy and Infectious Diseases, or NIAID, a division of the National Institutes of Health, or NIH, collectively, the NIH Grants. The Company considers the grants receivable to be fully collectible; accordingly, no allowance for doubtful amounts has been established. If amounts become uncollectible, they are charged to operations.

Property and Equipment

Property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful lives of the assets. Such lives vary from three to five years. Leasehold improvements are amortized over the lesser of the life of the lease or the life of the asset.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets with definite lives, such as property and equipment, for impairment. The Company records impairment losses on long-lived assets used for operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the carrying value of the assets. There have not been any impairment losses of long-lived assets through June 30, 2012.

Income Taxes

The provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740-10, Uncertainty in Income Taxes, address the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC 740-10, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Company has determined that it has no uncertain tax positions.

The Company accounts for income taxes using the asset and liability method to compute the differences between the tax basis of assets and liabilities and the related financial amounts, using currently enacted tax rates.

The Company has deferred tax assets, which are subject to periodic recoverability assessments. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. The Company evaluates the recoverability of the deferred tax assets annually.

Revenue Recognition

The Company’s revenues are generated from the NIH and U.S. Treasury grant awards and a feasibility study agreement, or the Collaboration Agreement, that the Company entered into with a third party in July 2010. The revenue from the NIH and U.S. Treasury grant awards are based upon subcontractor and internal costs incurred that are specifically covered by the grant, and where applicable, a facilities and administrative rate that provides funding for overhead expenses. These revenues are recognized when expenses have been incurred by subcontractors or when the Company incurs internal expenses that are related to the grant.

The revenue from the Collaboration Agreement is derived from the completion of certain development services and the reimbursement of certain development costs incurred to provide such development services. Revenue from upfront, nonrefundable service fees are recognized when earned, as evidenced by written acknowledgement from the collaborator, or other persuasive evidence that all service deliverables have been achieved, provided that the service deliverables are substantive and their achievability was not reasonably assured at the inception of the Collaboration Agreement. Any amounts received prior to satisfying the Company’s revenue recognition criteria are recorded as deferred revenue.

Research and Development Costs

All research and development costs are charged to expense as incurred. Such costs primarily consist of lab supplies, contract services, stock-based compensation expense, salaries and related benefits.

Stock-based Compensation

The Company accounts for stock-based compensation in accordance with FASB ASC Topic 718, which establishes accounting for equity instruments exchanged for employee services. Under such provisions, stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee’s requisite service period (generally the vesting period of the equity grant).

The Company accounts for equity instruments, including restricted stock or stock options, issued to non-employees in accordance with authoritative guidance for equity-based payments to non-employees. Stock options issued to non-employees are accounted for at their estimated fair value determined using the Black-Scholes option-pricing model. The fair value of options granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the period the related services are rendered. Restricted stock issued to non-employees is accounted for at estimated fair value as they vest.

Net Loss per Share

Net loss per share is presented as both basic and diluted net loss per share. Basic net loss per share excludes any dilutive effects of options, shares subject to repurchase and warrants. Diluted net loss per share includes the impact of potentially dilutive securities. No dilutive effect was calculated for the three or six months ended June 30, 2012 and 2011 as the Company reported a net loss for each respective period and the effect would have been anti-dilutive. The Company had outstanding common share equivalents of 6,099,442 and 5,582,918 at June 30, 2012 and 2011, respectively.

3. Significant Agreements and Contracts

License Agreement with OPKO Health, Inc.

In June 2009, the Company entered into a limited license agreement, or the OPKO License, with OPKO Health, Inc., or OPKO, pursuant to which the Company granted OPKO an exclusive, royalty-free, worldwide license under all U.S. and foreign patents and patent applications owned or controlled by the Company or any of its affiliates, or the STI Patents, to: (i) develop, manufacture, use, market, sell, offer to sell, import and export certain products related to the development, manufacture, marketing and sale of drugs for ophthalmological indications, or the OPKO Field, and (ii) use and screen any population of distinct molecules covered by any claim of the STI Patents or which is derived by use of any process or method covered by any claim of the STI Patents to identify, select and commercialize certain products within the OPKO Field. Subject to certain limitations, OPKO will have the right to sublicense the foregoing rights granted under the OPKO License. Additionally, pursuant to the OPKO License, OPKO has granted the Company an exclusive, royalty-free, worldwide license to any patent or patent application owned or controlled by OPKO or any of its affiliates to develop, use, make, market, sell and distribute certain products in any field of use, other than the OPKO Field, or the OPKO Patents.

The Company has retained all rights to the STI Patents outside of the OPKO Field and has agreed not to practice the OPKO Patents or the STI Patents outside the STI current field of use. Unless otherwise terminated in accordance with its terms, the OPKO License will expire upon the expiration of the last to expire patent within the STI Patents and OPKO Patents on a country-by-country basis.

License Agreement with The Scripps Research Institute

In January 2010, the Company entered into a license agreement, or the TSRI License, with The Scripps Research Institute, or TSRI. Under the TSRI License, TSRI granted the Company an exclusive, worldwide license to certain TSRI patent rights and materials based on quorum sensing for the prevention and treatment of various bacterial infections such as Clostridium difficile (“C. diff”) and Staphylococcus aureus (“Staph”), including Methicillin-resistant Staph. In consideration for the license, the Company: (i) issued TSRI a warrant for the purchase of common stock, (ii) agreed to pay TSRI a certain annual royalty commencing in the first year after certain patent filing milestones are achieved, and (iii) agreed to pay a royalty on any sales of licensed products by the Company or its affiliates and a royalty for any revenues generated by the Company through its sublicense of patent rights and materials licensed from TSRI under the TSRI License. The TSRI License requires the Company to indemnify TSRI for certain breaches of the agreement and other matters customary for license agreements. The parties may terminate the TSRI License at any time by mutual agreement. In addition, the Company may terminate the TSRI License by giving 60 days notice to TSRI and TSRI may terminate the TSRI License immediately in the event of certain breaches of the agreement by the Company or upon the Company’s failure to undertake certain activities in furtherance of commercial development goals. Unless terminated earlier by either or both parties, the term of the TSRI License will continue until the final expiration of all claims covered by the patent rights licensed under the agreement. For the three months ended June 30, 2012 and 2011 and for the period from inception (January 25, 2006)(“Inception”) through June 30, 2012, the Company recorded $14,348, $838 and $108,078 in patent prosecution and maintenance costs associated with the TSRI License, respectively. For the six months ended June 30, 2012 and 2011, the Company recorded $16,568 and $1,063 in patent prosecution and maintenance costs associated with the TSRI License, respectively. All such costs have been included in general and administrative expenses.

The fair value of the warrants to purchase Company common stock, issued in connection with the TSRI License, of $17,989 was determined using the Black-Scholes valuation model with the following weighted-average assumptions: risk-free interest rate of 2.48%, no dividend yield, expected term of 10 years, and volatility of 102%. Such fair value has been included in general and administrative expenses for the period from Inception through June 30, 2012.

NIH Grants

In May 2010, the NIAID awarded the Company an Advanced Technology Small Business Technology Transfer Research grant to support the Company’s program to generate and develop novel antibody therapeutics and vaccines to combat Staph infections, including Methicillin-resistant Staph, or the Staph Grant award. The project period for the Staph Grant award covered a two-year period which commenced in June 2010 and ended in May 2012. As of June 30, 2012, the entire Phase 1 grant of $600,000 had been awarded and recognized as revenue. The Company records revenue associated with the grant as the related costs and expenses are incurred. During the three months ended June 30, 2012 and 2011 and for the period from Inception through June 30, 2012, the Company recorded $62,863, $74,156 and $600,000 of revenue associated with the Staph Grant award, respectively. During the six months ended June 30, 2012 and 2011, the Company recorded $119,379 and $109,521 of revenue associated with the NIH Grant, respectively.

In July 2011, the NIAID awarded the Company a second Advanced Technology Small Business Technology Transfer Research grant to support the Company’s program to generate and develop antibody therapeutics and vaccines to combat C. diff infections, or the C. diff Grant award. The project period for the C. diff Grant award covers a two-year period which commenced in June 2011, and as of June 30, 2012, the entire Phase 1 grant of $600,000 had been awarded. During the three and six months ended June 30, 2012 and for the period from Inception through June 30, 2012, the Company recorded $117,471, $171,104 and $284,302 of revenue associated with the C. diff Grant award, respectively.

In June 2012, the NIAID awarded the Company a third Advanced Technology Small Business Technology Transfer Research grant, with an initial award of $300,000, to support the Company’s program to generate and develop novel human antibody therapeutics to combat Staph infections, including Methicillin-resistant Staph. The project period for the phase I grant covers a two-year period which commenced in June 2012, with a potential annual award of $300,000 per year. The Company records revenue associated with the grant as the related costs and expenses are incurred. During the three and six months ended June 30, 2012 and for the period from Inception through June 30, 2012, the Company recorded $36,801 of revenue associated with such grant.

Collaboration Agreement

In July 2010, the Company entered into the Collaboration Agreement, with a third party. Under the terms of the Collaboration Agreement, the Company provided certain antibody screening services for an upfront cash fee of $200,000 and was reimbursed for certain costs and expenses associated with providing the services, or the Development Costs. The upfront fee and reimbursable Development Costs were accounted for as separate units of accounting. The Company recorded the gross amount of the reimbursable Development Costs as revenue and the costs associated with these reimbursements are reflected as a component of research and development expense.

Any amounts received by the Company pursuant to the Collaboration Agreement prior to satisfying the Company’s revenue recognition criteria are recorded as deferred revenue. For the three and six months ended June 30, 2011 and for the period from Inception through June 30, 2012, the Company recognized revenue of $0, $200,000 and $223,453, respectively. For the three and six months ended June 30, 2012, the Company recognized revenue of $0.

U.S. Treasury Grants

During 2010, the U.S. Treasury awarded the Company grants totaling $394,480 for investments in qualifying therapeutic discovery projects under section 48D of the Internal Revenue Code. The proceeds from this grant covered the reimbursement of qualified expenses incurred in 2009 and 2010, and are recognized as grant revenues in the period from Inception through June 30, 2012.

4. Stockholders’ Equity

Common Stock

In December 2011, the Company entered into a Stock Purchase Agreement, or the Stock Purchase Agreement, and issued 12,500,000 shares of common stock, in a private placement transaction, at $0.16 per share for aggregate gross proceeds of $2.0 million. In May 2012, the Company entered into an Amended and Restated Stock Purchase Agreement, and issued 37,500,000 shares of common stock, in a private placement transaction, at $0.16 per share for aggregate gross proceeds of $6.0 million. 6,250,000 of the shares were purchased by an investor, Hongye SD Group, LLC, of which Dr. Henry Ji, our interim Chief Executive Officer and Chief Scientific Officer, is a managing director.

Stock Incentive Plans

2009 Equity Incentive Plan

In February 2009, prior to the Merger, the Company’s Board of Directors approved the 2009 Equity Incentive Plan, or the EIP, under which 10,000,000 shares of common stock were reserved for issuance to employees, non-employee directors and consultants of the Company. The EIP provided for the grant of incentive stock options, non-incentive stock options, restricted stock awards and stock bonus awards to eligible recipients. In March 2009, the Company issued 7,403,861 restricted common stock awards to certain consultants for aggregate gross proceeds of $291. The restricted shares vest monthly over four years and the Company has the option to repurchase any unvested shares at the original purchase price upon any voluntary or involuntary termination. Any unvested shares immediately vest in the event of a merger, sale, or other transaction resulting in a change in control of the Company. In January 2011, the Company repurchased 1,104,135 unvested shares of restricted common stock for $43.

At June 30, 2012, 1,006,942 shares were unvested and subject to repurchase by the Company. The Company has the right of first refusal to purchase any proposed disposition of shares issued under the EIP. As a result of the Merger, no further shares are available for grant under the EIP.

2009 Non-Employee Director Grants

In September 2009, prior to the adoption of the 2009 Stock Incentive Plan, the Company’s Board of Directors approved the reservation and issuance of 200,000 nonstatutory stock options to the Company’s non-employee directors. The outstanding options vested on the one year anniversary of the vesting commencement date in October 2010. Such options are exercisable on the two year anniversary of the grant date and are generally exercisable for up to ten years from the grant date. As of December 31, 2010, no further shares may be granted under this plan and, as of June 30, 2012, 120,000 options were outstanding.

2009 Stock Incentive Plan

In October 2009, the Company’s stockholders approved the 2009 Stock Incentive Plan, or the Stock Plan, which became effective in December 2009 and under which 14,400,000 shares of the Company’s common stock are reserved for issuance to employees, non-employee directors and consultants of the Company. In addition, the number of shares reserved for issuance under the Stock Plan will be automatically increased annually on the first day of each fiscal year by the lesser of: (i) 1% of the aggregate number of shares of the Company’s common stock outstanding on the last day of the immediately preceding fiscal year, (ii) 1,200,000 shares, or (iii) an amount approved by the administrator of the Stock Plan. The Stock Plan provides for the grant of incentive stock options, non-incentive stock options, stock appreciation rights, restricted stock awards, unrestricted stock awards, restricted stock unit awards and performance awards to eligible recipients. Recipients of stock options shall be eligible to purchase shares of the Company’s common stock at an exercise price equal to no less than the estimated fair market value of such stock on the date of grant. The maximum term of options granted under the Stock Plan is ten years. Employee option grants will generally vest 25% on each anniversary of the original vesting date over four years. The vesting schedules for grants to non-employee directors and consultants

will be determined by the Company’s Compensation Committee. Stock options are generally not exercisable prior to the applicable vesting date, unless otherwise accelerated under the terms of the applicable stock plan agreement. Unvested shares of the Company’s common stock issued in connection with an early exercise however, may be repurchased by the Company upon termination of the optionee’s service with the Company.

During the six months ended June 30, 2012 and 2011, the Company’s Board of Directors awarded 2,055,000 and 1,530,000 options, respectively, to certain employees and consultants and 9,407,500 and 10,165,000 shares were available for grant under the Stock Plan, respectively.

The Company uses the Black-Scholes valuation model to calculate the fair value of stock options. Stock based compensation expense is recognized over the vesting period using the straight-line method. The fair value of employee stock options was estimated at the grant date using the following assumptions:


	Six months ended June 30,
	2012	2011
Dividend yield	0	0
Volatility	102%	102%
Risk-free interest rate	1.02%	2.17% - 2.61%
Expected life of options	5.7 years	5.7 years

The weighted average grant date fair value per share of employee stock options granted during the six months ended June 30, 2012 and 2011 was $0.13 and $0.11, respectively.

The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. Due to the Company’s limited historical data, the estimated volatility incorporates the historical and implied volatility of comparable companies whose share prices are publicly available. The risk-free interest rate assumption was based on the U.S. Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The weighted average expected life of options was estimated using the average of the contractual term and the weighted average vesting term of the options.

The total employee stock-based compensation recorded as operating expenses was $27,937, $13,326 and $148,523 for the three months ended June 30, 2012 and 2011 and for the period from Inception through June 30, 2012, respectively. The total employee stock-based compensation recorded as operating expenses was $54,665 and $23,800 for the six months ended June 30, 2012 and 2011, respectively.

As of June 30, 2012, unrecognized compensation cost related to the employee options was $186,331, which will be recognized over 2.7 years.

The Company records equity instruments issued to non-employees as expense at their fair value over the related service period as determined in accordance with the applicable authoritative guidance and periodically revalues the equity instruments as they vest. Stock-based compensation expense related to non-employee consultants recorded as operating expenses was $74,152, $61,497 and $658,246 for the three months ended June 30, 2012 and 2011 and for the period from Inception through June 30, 2012, respectively. Stock-based compensation expense related to non-employee consultants recorded as operating expenses was $148,592 and $127,592 for the six months ended June 30, 2012 and 2011, respectively.

5. Income Taxes

The Company maintains deferred tax assets that reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. These deferred tax assets include net operating loss carryforwards, research credits and capitalized research and development. The net deferred tax asset has been fully offset by a valuation allowance because of the Company’s history of losses. Utilization of operating losses and credits may be subject to substantial annual limitation due to ownership change provisions of the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization.

Item 2.

Management’s Discussion and Analysis of Financial Condition and Results of Operations.

This Quarterly Report on Form 10-Q contains “forward-looking statements” about our expectations, beliefs or intentions regarding our potential product offerings, business, financial condition, results of operations, strategies or prospects. You can identify forward-looking statements by the fact that these statements do not relate strictly to historical or current matters. Rather, forward-looking statements relate to anticipated or expected events, activities, trends or results as of the date they are made and are often identified by the use of words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” or “will,” and similar expressions or variations. Because forward-looking statements relate to matters that have not yet occurred, these statements are inherently subject to risks and uncertainties that could cause our actual results to differ materially from any future results expressed or implied by the forward-looking statements. Many factors could cause our actual activities or results to differ materially from the activities and results anticipated in forward-looking statements. These factors include those described under the caption “Risk Factors” included elsewhere in this Quarterly Report on Form 10-Q and in our other filings with the Securities and Exchange Commission, or the SEC. Furthermore, such forward-looking statements speak only as of the date of this report. We undertake no obligation to update any forward-looking statements to reflect events or circumstances occurring after the date of such statements.

Overview

We are a development stage biopharmaceutical company focused on the discovery, development and commercialization of novel and/or proprietary biotherapeutics for the treatment of a variety of disease conditions, including cancer, inflammation, metabolic and infectious diseases. In 2011, we identified and further developed a number of potential drug product candidates across various therapeutic areas, and intend to select several lead product candidates to progress into preclinical development activities in 2012 and 2013. It is too early to assess which of these candidates, if any, will merit further evaluation in clinical trials. Our libraries were designed to facilitate the rapid identification and isolation of highly specific, antibody therapeutic product candidates that are fully human and that bind to disease targets appropriate for antibody therapy. In 2011, we built our initial antibody expression and production capabilities to enable us to make sufficient product material to conduct preclinical safety and efficacy testing in animal models.

Our therapeutic objective is to develop two classes of antibody drug products: (i) First in Class, or FIC, and/or (ii) biobetters. Although we intend to retain ownership and control of some product candidates by advancing them further into preclinical development, we will also consider partnerships with pharmaceutical or biopharmaceutical organizations, with the appropriate experience and expertise, in order to balance the risks associated with drug discovery and development and maximize our stockholders’ returns. Our partnering objectives include generating revenue through license fees, milestone related development fees and royalties by licensing rights to our development candidates.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based upon our financial statements which are prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, related disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. We continually evaluate our estimates and judgments, the most critical of which are those related to income taxes and stock-based compensation. We base our estimates and judgments on historical experience and other factors that we believe to be reasonable under the circumstances. Materially different results can occur as circumstances change and additional information becomes known.

During the three and six months ended June 30, 2012, there were no significant changes to the items that we disclosed as our critical accounting policies and estimates in Note 2 to our financial statements for the year ended December 31, 2011 contained in our 2011 Form 10-K, as filed with the SEC.

Results of Operations

The following describes certain line items set forth in our condensed statements of operations.

Three Months Ended June 30, 2012 Compared to the Three Months Ended June 30, 2011

Revenues. Revenues were $217,135 for the three months ended June 30, 2012, as compared to $74,156 for the three months ended June 30, 2011. The increase is due to increased activities under three active NIH Grants in the three months ended June 30, 2012 as compared to only one active grant for the three months ended June 30, 2011.

In May 2010, we were awarded an Advanced Technology Small Business Technology Transfer Research grant to support our program to generate and develop novel antibody therapeutics and vaccines to combat Staph infections, including Methicillin- resistant Staph, or the Staph Grant award. The project period for this grant covered a two-year period, and as of June 30, 2012, the entire Phase 1 grant of $600,000 had been awarded and recognized as revenue.

In July 2011, we were awarded a second Advanced Technology Small Business Technology Transfer Research grant to support our program to generate and develop antibody therapeutics and vaccines to combat C. diff infections, or the C. diff Grant award. The project period for the C. diff Grant award covers a two-year period which commenced in June 2011, and as of June 30, 2012, the entire Phase 1 grant of $600,000 had been awarded. From July 2011 through June 30, 2012, $284,302 of the C. diff Grant award had been recorded in grant revenue.

In June 2012, we were awarded a third Advanced Technology Small Business Technology Transfer Research grant, with an initial award of $300,000, to support our program to generate and develop novel human antibody therapeutics to combat Staph infections, including Methicillin-resistant Staph, or the Staph Grant II award. The project period for the phase I grant covers a two-year period which commenced in June 2012, with a potential annual award of $300,000 per year. During June 2012, $36,801 of the award had been recorded in grant revenue.

We had no other revenue during the three months ended June 30, 2012 as we have not yet developed any product candidates for commercialization or earned any licensing or royalty payments. We expect that any revenue we generate will fluctuate from quarter to quarter as a result of the timing and amount of grant awards and when the related costs and expenses are incurred, and timing of any other payments received under our strategic collaborations.

Research and Development Expenses. Research and development expenses for the three months ended June 30, 2012 and 2011 were $917,452 and $636,301, respectively. Research and development expenses include all costs incurred in the development of our libraries, the costs to identify, isolate and advance human antibody drug candidates derived from our libraries, and the expenses associated with fulfilling our development obligations related to the Staph, Staph II and C. diff Grant awards, collectively the NIH Grants. Such expenses consist primarily of salaries and personnel related expenses, stock-based compensation expense, laboratory supplies, consulting costs, preclinical testing costs, depreciation and other expenses. The increase of $281,151 is attributable to salaries, stock-based compensation expense, consulting costs, lab supply costs, preclinical testing costs and depreciation expenses incurred in connection with expanded research and development activities, including under the NIH Grants. We expect research and development expenses to increase in absolute dollars as we incur incremental expenses associated with our continued efforts to progress into preclinical development activities in the latter part of 2012 and 2013.

General and Administrative Expenses. General and administrative expenses for the three months ended June 30, 2012 and 2011 were $244,557 and $527,226, respectively. General and administrative expenses consist primarily of salaries and personnel related expenses for executive, finance and administrative personnel, stock-based compensation expense, professional fees, infrastructure expenses, legal and accounting expenses and other general corporate expenses. The decrease of $282,669 is primarily attributable to decreased salaries related to the departure of our former Chief Executive Officer and general legal costs. In April 2011, the Company paid its former Chief Executive Officer severance in the amount of one year’s base salary, or $250,000, as provided for under his employment agreement. We expect general and administrative expenses to increase in absolute dollars as we incur incremental expenses associated with ongoing operations and compliance with our public reporting obligations.

Interest Income. Interest income for the three months ended June 30, 2012 and 2011 was $1,756 and $1,734, respectively.

Net Loss. Net loss for the three months ended June 30, 2012 and 2011 was $943,119 and $1,087,637, respectively. The decrease in net loss is mainly attributable to the higher revenues.

Six Months Ended June 30, 2012 Compared to the Six Months Ended June 30, 2011

Revenues. Revenues were $327,284 for the six months ended June 30, 2012, as compared to $309,521 for the six months ended June 30, 2011. The net increase is due to the following substantially offsetting factors: (i) increased activities under three active NIH Grants in the six months ended June 30, 2012 as compared to only one active grant for the six months ended June 30, 2011, and (ii) non-recurring collaboration revenue of $200,000 earned under the Collaboration Agreement in 2011.

We expect that any revenue we generate will fluctuate from quarter to quarter as a result of the timing and amount of grant awards and when the related costs and expenses are incurred, and timing of any other payments received under our strategic collaborations.

Research and Development Expenses. Research and development expenses for the six months ended June 30, 2012 and 2011 were $1,716,524 and $1,224,945, respectively. Research and development expenses include all costs incurred in the development of our libraries, the costs to identify, isolate and advance human antibody drug candidates derived from our libraries, and the expenses associated with fulfilling our development obligations related to the NIH Grants. Such expenses consist primarily of salaries and

personnel related expenses, stock-based compensation expense, laboratory supplies, consulting costs, preclinical testing costs, depreciation and other expenses. The increase of $491,579 is attributable to salaries, stock-based compensation expense, consulting costs, lab supply costs, preclinical testing costs and depreciation expenses incurred in connection with expanded research and development activities, including under the NIH Grants. We expect research and development expenses to increase in absolute dollars as we incur incremental expenses associated with our continued efforts to progress into preclinical development activities in the latter part of 2012 and 2013.

General and Administrative Expenses. General and administrative expenses for the six months ended June 30, 2012 and 2011 were $463,232 and $860,032, respectively. General and administrative expenses consist primarily of salaries and personnel related expenses for executive, finance and administrative personnel, stock-based compensation expense, professional fees, infrastructure expenses, legal and accounting expenses and other general corporate expenses. The decrease of $396,800 is primarily attributable to decreased salaries related to the departure of our former Chief Executive Officer, general legal costs and travel expenses. In April 2011, the Company paid its former Chief Executive Officer severance in the amount of one year’s base salary. We expect general and administrative expenses to increase in absolute dollars as we incur incremental expenses associated with ongoing operations and compliance with our public reporting obligations.

Interest Income. Interest income for the six months ended June 30, 2012 and 2011 was $3,228 and $3,376, respectively.

Net Loss. Net loss for the six months ended June 30, 2012 and 2011 was $1,849,244 and $1,772,080, respectively. The increase in net loss is mainly attributable to the expanded research and development activities which were substantially offset by the lower general and administrative expenses.

Liquidity and Capital Resources

As of June 30, 2012, we had $7,625,277 in cash and cash equivalents, attributable primarily to the closing of the private placement of our common stock for aggregate gross proceeds of $6,000,000 in May 2012.

Cash Flows from Operating Activities. Net cash used for operating activities was $1,468,850 for the six months ended June 30, 2012 and is primarily attributable to our net loss of $1,849,244, a net increase of $45,208 in working capital balances, partially offset by $335,186 in non-cash activities relating to stock-based compensation and depreciation expense. Net cash used for operating activities was $1,613,940 for the six months ended June 30, 2011, and primarily reflects a net loss of $1,772,080, a net decrease of $50,278 in working capital balances, partially offset by $208,418 in non-cash activities relating to stock-based compensation and depreciation expense.

We expect to continue to incur substantial and increasing losses and have negative net cash flows from operating activities as we seek to expand and support our technology portfolio and research and development activities.

Cash Flows from Investing Activities. Net cash used for investing activities was $310,653 for the six months ended June 30, 2012 as compared to $749,131 for the six months ended June 30, 2011. The net cash used related primarily to equipment acquired for research and development activities.

We expect to increase our investment in laboratory equipment as we seek to expand and progress our research and development activities.

Cash Flows from Financing Activities. Cash provided by financing activities for the six months ended June 30, 2012 was $5,938,231, which was primarily derived from the sale of $6,000,000 of our common stock in a private placement transaction in May 2012. Net cash provided by financing activities for the six months ended June 30, 2011 was nominal.

Future Liquidity Needs. From Inception through June 30, 2012, we have principally financed our operations through private equity financings with aggregate net proceeds of $15,468,776, as we have not generated any product-related revenue from operations to date, and do not expect to generate significant revenue for several years, if ever. We will need to raise additional capital before we exhaust our current cash resources in order to continue to fund our research and development, including our long-term plans for pre-clinical trials and new product development, as well as to fund operations generally. As and if necessary, we will seek to raise additional funds through various potential sources, such as equity and debt financings, or through corporate collaboration and license agreements. We can give no assurances that we will be able to secure such additional sources of funds to support our operations, or, if such funds are available to us, that such additional financing will be sufficient to meet our needs.

Based on our resources at June 30, 2012, and our current plan of expenditure on research and development programs, we believe that we will have sufficient capital to fund our operations for at least twelve months. Our actual cash requirements may vary materially from those now planned, however, because of a number of factors, including the pursuit of development of product candidates, competitive and technical advances, costs of commercializing any potential product candidates, and costs of filing, prosecuting, defending and enforcing any patent claims and any other intellectual property rights. If we are unable to raise additional funds when

needed, we may not be able to develop any product candidates, we could be required to delay, scale back or eliminate some or all of our research and development programs and we may need to wind down our operations altogether. Each of these alternatives would have a material adverse effect on our business.

To the extent that we raise additional funds by issuing equity or debt securities, our stockholders may experience additional significant dilution and such financing may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates, or grant licenses on terms that may not be favorable to us. These things may have a material adverse effect on our business.

Additionally, recent global market and economic conditions have been unprecedented and challenging with tighter credit conditions and recession in most major economies. As a result of these market conditions, the cost and availability of credit has been and may continue to be adversely affected by illiquid credit markets and wider credit spreads. Concern about the stability of the markets generally and the strength of counterparties specifically has led many lenders and institutional investors to reduce, and in some cases, cease to provide credit to businesses and consumers. These factors have led to a decrease in spending by businesses and consumers alike, and a corresponding decrease in global infrastructure spending. Continued turbulence in the U.S. and international markets and economies and prolonged declines in business and consumer spending may adversely affect our liquidity and financial condition, including its ability to access the capital markets to meet liquidity needs.

Off-Balance Sheet Arrangements

Since our inception through June 30, 2012, we have not engaged in any off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K.

New Accounting Pronouncements

None.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk.

As a smaller reporting company, as defined by Section 10(f)(1) of Regulation S-K, we are not required to provide the information set forth in this Item.

Item 4.

Controls and Procedures.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s regulations, rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. As required by Rule 13a-15(b) promulgated by the SEC under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on the foregoing, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended June 30, 2012 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.

Legal Proceedings.

To the best of our knowledge, we are not a party to any legal proceedings that, individually or in the aggregate, are deemed to be material to our financial condition or results of operations.

Item 1A.

Risk Factors.

Our Annual Report on Form 10-K for the year ended December 31, 2011, Part I –Item 1A, Risk Factors, describes important risk factors that could cause our business, financial condition, results of operations and growth prospects to differ materially from those indicated or suggested by forward-looking statements made in this Form 10-Q or presented elsewhere by management from time to time. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business.

Set forth below are certain additions to our risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2011.

We could face adverse consequences as a result of the actions of an activist stockholder.

One of our stockholders is attempting to involve himself in the governance and strategic direction of our Company above and apart from normal interactions between stockholders and management. This stockholder has proposed an alternate slate of nominees for election to our board of directors at our 2012 annual meeting of stockholders. The alternate slate includes certain of our existing directors and members of management. Such activism, and any related negative publicity, could result in substantial costs that negatively impact our stock price and increase its volatility. In addition, such involvement could cause a diversion of the attention of our management and board of directors and create perceived uncertainties with existing and potential strategic partners impacting our ability to consummate potential transactions, collaborations or opportunities in furtherance of our strategic plan. In addition, such activism could make it more difficult to attract and retain qualified personnel, customers and business partners, which could disrupt the growth of the market for our potential product candidates, delay the development and commercialization of our potential product candidates and further adversely affect the trading price of our common stock and increase its volatility. In addition, the activist may have little or no experience in the biopharmaceutical industry or in public company oversight and governance, or they may seek to elect members to our board of directors with little or no experience in the biopharmaceutical industry or in public company oversight and governance, and the activist and any nominees may have a specific agenda different and apart from the majority of our stockholders.
