(the Company) was incorporated in Delaware on July 10, 2003. The Company is a regenerative medicine company focused on discovering, developing, manufacturing and commercializing a range of neo-organs, or products composed of living cells, with or without synthetic or natural materials, implanted or injected into the body to engraft into, regenerate, or replace a damaged tissue or organ.&#160;&#160;Using its Organ Regeneration Platform, the Company creates these neo-organs using a patient&#8217;s own cells, or autologous cells.&#160;&#160;The Company believes its proprietary product candidates harness the intrinsic regenerative pathways of the body to regenerate a range of native-like organs and tissues. The Company&#8217;s product candidates are intended to delay or eliminate the need for chronic disease therapies, organ transplantation, and the administration of anti-rejection medications.&#160;&#160;In addition, the Company&#8217;s neo-organs are designed to replace the need to substitute other tissues of the body for a purpose to which they are poorly suited.</font></div>

The Company operates as a single business segment. Operations of the Company are subject to certain risks and uncertainties, including, among others, uncertainty of product candidate development; technological uncertainty; dependence on collaborative partners; uncertainty regarding patents and proprietary rights; comprehensive government regulations; having no commercial manufacturing experience, marketing or sales capability or experience; and dependence on key personnel.</font></div>

The valuation of the Conversion Option, and Call Option is subjective and is affected by changes in inputs to the valuation model including the assumptions regarding the aggregate value of the Company&#8217;s debt and equity instruments; assumptions regarding the expected amounts and dates of future debt and equity financing activities; assumptions regarding the likelihood and timing of Fundamental Transactions or Major Transactions (as defined in the agreement); the historical and prospective volatility in the value of the company&#8217;s debt and equity instruments; risk-free rates based on U.S. Treasury security yields; and the Company&#8217;s dividend yield. In performing the valuation of the Conversion Option and Call Option, the Company believed the common stock price had not fully adjusted for the potential future dilution from this private placement. Therefore, the Company used an implied enterprise value considering potential future values for the Company contingent on the outcome of its research programs in conjunction with a Monte Carlo analysis to estimate the range of possible outcomes within each scenario and to allocate value to the securities in accordance with the terms of the agreements. The valuation resulted in a model-derived common stock value of $0.04 per share and $0.03 per share as of December 31, 2012 and March 31, 2013, respectively, primarily due to the preference rights of the debt holders and the anti-dilution and net cash settlement features of warrants issued in 2011 and 2012. Changes in these assumptions can materially affect the fair value estimate.</font></div>

The valuation of warrants is subjective and is affected by changes in inputs to the valuation model including the price per share of the Company&#8217;s common stock; assumptions regarding the expected amounts and dates of future debt and equity financing activities; assumptions regarding the likelihood and timing of Fundamental Transactions and, the historical volatility of the stock prices of the Company&#8217;s common stock; risk-free rates based on U.S. Treasury security yields; and the Company&#8217;s dividend yield.</font></div>

Therefore, the Company used an implied enterprise value considering potential future values for the Company contingent on the outcome of its research programs in conjunction with a Monte Carlo analysis to estimate the range of possible outcomes within each scenario and to allocate value to the securities in accordance with the terms of the agreements. The valuation resulted in a model-derived common stock value of $0.04 per share and $0.03 per share as of December 31, 2012 and March 31, 2013, respectively, primarily due to the preference rights of the debt holders and the anti-dilution and net cash settlement features of the 2011 and 2012 Warrants. Changes in these assumptions can materially affect the fair value estimate. The Company will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire, or are amended in a way that would no longer require these warrants to be classified as a liability.</font></font></div>

In addition, the following inputs were used in the valuation model: assumptions regarding the aggregate value of the Company&#8217;s debt and equity instruments, the amounts and dates of future debt financing transaction, and the historical and prospective volatility in the value of the Company&#8217;s debt and equity instruments. The Company used an implied enterprise value considering potential future values for the Company contingent on the outcome of its research programs in conjunction with a Monte Carlo analysis to estimate the range of possible outcomes within each scenario and to allocate value to the securities in accordance with the terms of the agreements. The valuation resulted in a model-derived common stock value of $0.04 per share and $0.03 per share as of December 31, 2012 and March 31, 2013, respectively, primarily due to the preference rights of the debt holders and the anti-dilution and net cash settlement features of the 2011 and 2012 Warrants. Changes in these assumptions can materially affect the fair value estimate. The Company will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire, or are amended in a way that would no longer require these warrants to be classified as a liability.</font></div>

Using our Organ Regeneration Platform, we create these neo-organs using a patient&#8217;s own cells, or autologous cells. We believe our proprietary product candidates harness the intrinsic regenerative pathways of the body to regenerate a range of native-like organs and tissues. Our product candidates are intended to delay or eliminate the need for chronic disease therapies, organ transplantation, and the administration of anti-rejection medications. In addition, our neo-organs are designed to replace the need to substitute other tissues of the body for a purpose to which they are poorly suited. Building on our clinical and preclinical experience, we are initially leveraging our Organ Regeneration Platform to develop our Neo-Urinary Conduit for bladder cancer patients who are in need of a urinary diversion and our Neo-Kidney Augment for patients with advanced chronic kidney disease.</font></div>

Since our inception in July 2003, we have had no revenue from product sales, and have funded our operations principally through the private and public sales of equity securities and debt financings. We have never been profitable and, as of March 31, 2013, we had an accumulated deficit of $252.9 million, including $48.4 million of cumulative accretion on the Redeemable Convertible Preferred Stock through April 2010. We expect to continue to incur significant operating losses for the foreseeable future as we advance our product candidates from discovery through preclinical studies and clinical trials and seek marketing approval and eventual commercialization.</font></div>

We expect that a large percentage of our research and development expense in the future will be incurred in support of our current and future preclinical and clinical development programs. These expenditures are subject to numerous uncertainties in timing and cost to completion. We expect to continue to test our product candidates in preclinical studies for toxicology, safety and efficacy, and to conduct additional clinical trials for each product candidate. If we are not able to engage a partner prior to the commencement of later stage clinical trials, we may fund these trials ourselves. As we obtain results from clinical trials, we may elect to discontinue or delay clinical trials for certain product candidates or programs in order to focus our resources on more promising product candidates or programs. Completion of clinical trials by us or our future collaborators may take several years or more, but the length of time generally varies according to the type, complexity, novelty and intended use of a product candidate. The cost of clinical trials may vary significantly over the life of a project as a result of differences arising during clinical development, including, among others:</font></div>

This evaluation was carried out under the supervision and with the participation of the Company&#8217;s management, including the Company&#8217;s Chief Executive Officer and Chief Financial Officer. The Company had previously reported a material weakness in internal control over financial reporting with respect to the misapplication of U.S. Generally Accepted Accounting Principles for the classification of debt financing costs. which was described in Item&#160;9A including Management&#8217;s Annual Report on Internal Control Over Financial Reporting in the Company&#8217;s Annual Report on Form 10-K for the year ended December&#160;31, 2012. This material weakness was the result of limited accounting and reporting resources and a lack of accounting expertise related to the initial classification of debt financing costs incurred for convertible debt issuances that include issuance of derivatives such as warrants and call options. This material weakness did not have an impact on our financial statements for the year ended December 31, 2012 as we made the appropriate correcting journal entries.&#160;&#160;As a result of this material weakness in the Company&#8217;s internal control over financial reporting related to the accounting for significant financing transactions, which was not remediated as of March&#160;31, 2013, the Company&#8217;s Chief Executive Officer and Chief Financial Officer concluded that the Company&#8217;s disclosure controls and procedures were not effective as of March&#160;31, 2013.</font></div>

  TENGION, INC.
  (A Development-Stage Company)
  Notes to Financial Statements
  (unaudited)
  (1)
  Organization and Nature of Operations
  Tengion, Inc. (the Company) was incorporated in Delaware on July 10, 2003. The Company is a regenerative medicine company focused on discovering, developing, manufacturing and commercializing a range of neo-organs, or products composed of living cells, with or without synthetic or natural materials, implanted or injected into the body to engraft into, regenerate, or replace a damaged tissue or organ.  Using its Organ Regeneration Platform, the Company creates these neo-organs using a patient's own cells, or autologous cells.  The Company believes its proprietary product candidates harness the intrinsic regenerative pathways of the body to regenerate a range of native-like organs and tissues. The Company's product candidates are intended to delay or eliminate the need for chronic disease therapies, organ transplantation, and the administration of anti-rejection medications.  In addition, the Company's neo-organs are designed to replace the need to substitute other tissues of the body for a purpose to which they are poorly suited.
  Building on its clinical and preclinical experience, the Company is initially leveraging its Organ Regeneration Platform to develop its Neo-Urinary Conduit for bladder cancer patients who are in need of a urinary diversion and its Neo-Kidney Augment for patients with advanced chronic kidney disease. The Company operates as a single business segment. Operations of the Company are subject to certain risks and uncertainties, including, among others, uncertainty of product candidate development; technological uncertainty; dependence on collaborative partners; uncertainty regarding patents and proprietary rights; comprehensive government regulations; having no commercial manufacturing experience, marketing or sales capability or experience; and dependence on key personnel.
  (2)
  Management's Plans to Continue as a Going Concern
  The accompanying financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business.
  The Company has incurred losses since inception and has a deficit accumulated during the development stage of $252.9 million as of March 31, 2013, including $48.4 million of cumulative accretion on redeemable convertible preferred stock through April 2010.  The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of its therapeutic product candidates currently in development or enters into cash flow positive business development transactions.
  Based upon the Company's current expected level of operating expenditures and debt repayment, and assuming the Company is not required to settle any outstanding warrants in cash or redeem, or pay cash interest on any of its Senior Secured Convertible Notes,  it expects to be able to fund operations through May 2013.  This period could be shortened if there are any unanticipated significant increases in planned spending on development programs or other unforeseen events.  The Company plans to raise additional funds through collaborative arrangements, public or private sales of debt or equity securities, commercial loan facilities, or some combination thereof.  There is no assurance that additional financing will be available when needed to allow the Company to continue its operations or if available, on terms acceptable to the Company.
  In the event financing is not obtained, the Company could pursue additional headcount reductions and other cost cutting measures to preserve cash as well as explore the sale of selected assets to generate additional funds.  If the Company is required to significantly reduce operating expenses and delay, reduce the scope of, or eliminate one or more of its development programs, these events could have a material adverse effect on the Company's business, results of operations and financial condition. In the event financing is not obtained, the Company will not be able to remain in business and will likely need to seek protection under the United States bankruptcy laws.
  These factors raise significant concerns about the Company's ability to continue as a going concern. The financial statements do not include any adjustments relating to recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.
  - 6 -
  (3)
  Use of Estimates
  The preparation of financial statements, in accordance with accounting principles generally accepted in the United States of America, 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.  Actual results could differ from those estimates.
  In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.
  (4)
  Net Loss Per Share
  Basic and diluted net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding. For all periods presented, the outstanding shares of unvested restricted stock as well as the number of common shares issuable upon exercise of outstanding stock options and warrants and conversion of notes payable have been excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Therefore, the weighted-average shares used to calculate both basic and dilutive loss per share are the same.
  The following potentially dilutive securities have been excluded from the computations of diluted weighted-average shares outstanding as they would be anti-dilutive:

  Financial Instruments
  The fair value guidance requires fair value measurements be classified and disclosed in one of the following three categories:
  - 7 -
  ·
  Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
  ·
  Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability;
  ·
  Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
  The following fair value hierarchy table presents information about each major category of the Company's financial assets and liability measured at fair value on a recurring basis as of December 31, 2012 and March 31, 2013 (in thousands).

  Lease liability
  The Company entered into an agreement in February 2006 to lease warehouse space effective March 1, 2011, at which time the Company determined it was not likely to utilize the space during the five-year lease term.  Therefore, the Company recorded a liability as of March 1, 2011, the cease-use date, for the fair value of its obligations under the lease.  The most significant assumptions used in determining the amount of the estimated lease liability are the potential sublease revenues and the credit-adjusted risk-free rate utilized to discount the estimated future cash flows.
  In connection with the 2011 restructuring, the Company determined it was not likely to utilize substantially all of the leased office and manufacturing space in its East Norriton, Pennsylvania facility during the remainder of the lease term.  Therefore, the Company recorded a liability as of November 30, 2011, the cease-use date, for the fair value of its obligations under the lease.
  The following table summarizes the activity related to the lease liability for the periods ended December 31, 2012 and March 31, 2013 (in thousands).

  The Company recorded interest expense of $0.2 million and $1.4 million for the three months ended March 31, 2012 and 2013, respectively. Included in interest expense in 2013 is $0.2 million of issuance costs related to the 2012 Financing and $0.5 million of amortization of these issuance costs and $0.2 million in amortization of deferred financing costs and debt discount on the Senior Secured Convertible Notes and Working Capital Note.
  Senior Secured Convertible Notes
  On October 2, 2012, the Company completed a private placement of an aggregate principal amount of $15.0 million of Senior Secured Convertible Notes (the Convertible Notes) along with warrants to the holders of the Convertible Notes (2012 Warrants) to purchase approximately 51.1 million shares of common stock at an initial exercise price of $0.75 per share.  The Company recorded an embedded derivative liability for the Conversion Option (the Conversion Option).  The Conversion Option is presented with the Convertible Notes. See Note 10 for further discussion of this embedded derivative liability.
  At the time of the issuance of the Convertible Notes, the Company also granted the holders of the Convertible Notes the right to require the Company to sell to such holders up to an additional $20 million in securities on the same terms as the Convertible Notes and 2012 Warrants (the Call Option) (collectively with the Convertible Notes and 2012 Warrants, the 2012 Financing).  The Call Option may be exercised by the holders of the Convertible Notes at any time or from time to time on or before June 30, 2013.  The Company recorded a derivative liability for the Call Option.  See Note 10 for further discussion of this derivative liability.
  On December 31, 2012, January 30, 2013, and February 14, 2013, the Company entered into amendment agreements with the holders of the Convertible Notes. Pursuant to these amendments, the holders agreed to extend the interest payments that were due to them on January 1, 2013 to February 15, 2013. The aggregate amount of the interest payment due on January 1, 2013 was $0.4 million, which amount continued to accrue interest at the rate of 10% per annum.  On February 14, 2013, the Company and the investors entered into amendments to the terms of the 2012 Financing which gave the Company the option to pay interest payments on the Notes with restricted common stock.
  Additionally, the amendments extended the deadline required under the registration rights agreement to register the shares underlying the Convertible Notes and 2012 Warrants from December 31, 2012 to March 31, 2013.  On March 28, 2013 the registration statement on form S-1 (the Registration Statement) covering the resale of the shares of common stock issuable upon the conversion of the Convertible Notes and the exercise of the 2012 Warrants was declared effective by the SEC.
  On April 6, 2013, the conversion price of the Convertible Notes was adjusted to $0.69 per share, the exercise price of the 2012 Warrants was adjusted to $0.69 per share, and the number of shares issuable upon exercise of the 2012 Warrants was increased to 57,438,408 shares.  The Registration Statement filed by the Company with the SEC to register the number of 2012 Warrant shares permitted under the limitations imposed by the SEC became effective at 4:00 p.m. on March 28, 2013.  The effectiveness of the Registration Statement triggered an adjustment of the exercise price of the 2012 Warrants and the conversion price of the Convertible Notes. The volume weighted average price (the VWAP) of the Company's common stock from April 1, 2013 through April 5, 2013, the five trading days after the Registration Statement became effective (the Post-Registration Period), was $0.69, which was lower than the exercise price or conversion price for the 2012 Warrants and Convertible Notes in effect immediately prior to the expiration of the Post-Registration Period.  Pursuant to the terms of the Convertible Notes and 2012 Warrants, the exercise price and conversion price for the 2012 Warrants and Convertible Notes were adjusted to the value of the VWAP for the Post-Registration Period, and the number of shares issuable upon exercise of the 2012 Warrants was proportionately increased.

  Capital Structure
  Common Stock
  Since inception, the Company has sold common stock to certain officers, directors, employees, consultants, and Scientific Advisory Board members.  As of March 31, 2013, the Company is authorized to issue 750,000,000 shares of common stock.  Each holder of common stock is entitled to one vote for each share held.  The Company will, at all times, reserve and keep available out of its authorized but unissued shares of common stock sufficient shares to affect the exercise of outstanding stock options and warrants.
  In connection with the March 2011 equity financing, the Company filed a registration statement with the SEC for the registration of the total number of shares sold to the investors and shares issuable upon exercise of the warrants and the registration statement was declared effective by the SEC on May 16, 2011.  The Company is required to use commercially reasonable efforts to cause the registration statement to remain continuously effective until such time when all of the registered shares are sold or such shares may be sold by non-affiliates without volume or manner-of-sale restrictions pursuant to Rule 144 of the Securities Act and without the requirement for the Company to be in compliance with the current public information requirement under Rule 144.  In the event the Company fails to meet certain legal requirements in regards to the registration statement, it will be obligated to pay the investors, as partial liquidated damages and not as a penalty, an amount in cash equal to 1.5% of the aggregate purchase price paid by investors for each monthly period that the registration statement is not effective, up to a maximum aggregate payment of 6% of the purchase price paid by investors, except that if the Company fails to satisfy the current public information requirement pursuant to Rule 144(c)(1), the maximum aggregate payment would be 12% of the purchase price paid by investors.  If the Company determines a registration payment arrangement in connection with the securities issued in March 2011 is probable and can be reasonably estimated, a liability will be recorded. As of December 31, 2012 and March 31, 2013, the Company concluded the likelihood of having to make any payments under the arrangements was remote, and therefore did not record any related liability.
  Preferred Stock
  The Company was authorized to issue 10,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges, and restrictions thereof.  These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock.  The issuance of the Company's preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation.  In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change of control of the Company or other corporate action.  There are no shares issued or outstanding as of March 31, 2013.

  Embedded Derivative Conversion Options and Call Option Derivative Liability
  The Company accounts for the Conversion Option in accordance with ASC 815, Derivatives and Hedging (ACS 815). Under this accounting guidance, the Company is required to bifurcate the embedded derivative from the host instrument and account for it as a derivative financial instrument. The Company also accounts for the Call Option issued in connection with the 2012 Financing in accordance with ASC 815, as this instrument is considered a free-standing financial instrument that meets the criteria of a derivative under the guidance.
  On October 2, 2012, the Company issued the Convertible Notes as discussed in Note 9 and classified the fair value of the Conversion Option and Call Option as a derivative liability. The Company will continue to re-measure their fair values at each reporting date, with any changes in fair value being recorded on the Statement of Operations and Comprehensive Loss.
  - 11 -
  The fair value of the Conversion Option and Call Option as of December 31, 2012 and as of March 31, 2013, was determined using a risk-neutral framework within a Monte Carlo analysis. The valuation of the Conversion Option, and Call Option is subjective and is affected by changes in inputs to the valuation model including the assumptions regarding the aggregate value of the Company's debt and equity instruments; assumptions regarding the expected amounts and dates of future debt and equity financing activities; assumptions regarding the likelihood and timing of Fundamental Transactions or Major Transactions (as defined in the agreement); the historical and prospective volatility in the value of the company's debt and equity instruments; risk-free rates based on U.S. Treasury security yields; and the Company's dividend yield. In performing the valuation of the Conversion Option and Call Option, the Company believed the common stock price had not fully adjusted for the potential future dilution from this private placement. Therefore, the Company used an implied enterprise value considering potential future values for the Company contingent on the outcome of its research programs in conjunction with a Monte Carlo analysis to estimate the range of possible outcomes within each scenario and to allocate value to the securities in accordance with the terms of the agreements. The valuation resulted in a model-derived common stock value of $0.04 per share and $0.03 per share as of December 31, 2012 and March 31, 2013, respectively, primarily due to the preference rights of the debt holders and the anti-dilution and net cash settlement features of warrants issued in 2011 and 2012. Changes in these assumptions can materially affect the fair value estimate.
  The following table summarizes the calculated aggregate fair values using a risk-neutral framework within a Monte Carlo analysis of the Conversion Option and the Call Option as of the dates indicated along with assumptions utilized in each calculation.

  Warrants
  The Company accounts for stock warrants as either equity instruments or derivative liabilities depending on the specific terms of the warrant agreement.  Stock warrants are accounted for as derivative liabilities if the stock warrants allow for cash settlement or provide for modification of the warrant exercise price in the event subsequent sales of common stock are at a lower price per share than the then-current warrant exercise price.  The Company classifies derivative warrant liabilities on the balance sheet as a current liability, which is revalued at each balance sheet date subsequent to the initial issuance of the stock warrant.

The effectiveness of the Registration Statement on March 28, 2013 triggered an adjustment of the exercise price of the 2012 Warrants and increased the number of warrants.
  Liability-classified Warrants
  2011 Warrants
  In March 2011, the Company issued warrants (2011 Warrants) to purchase 1,046,102 shares of common stock in connection with a private placement transaction.  Each warrant was exercisable in whole or in part at any time until March 4, 2016 at a per share exercise price of $28.80, subject to certain adjustments as specified in the warrant agreement.  The Company valued the warrants as derivative financial instruments as of the date of issuance (March 4, 2011) and will continue to do so at each reporting date, with any changes in fair value being recorded on the Statement of Operations.  On December 31, 2012, the Company commenced an offer to the holders of 2011 Warrants to amend and restate the 2011 Warrants.  Following execution by the holders of the Exchange Agreements and receipt of the Amended and Restated 2011 Warrants, such holders had the right in the aggregate to purchase 27,388,851 shares of common stock at an exercise price of $1.10. Effective April 6, 2013, the 2011 Warrants have been adjusted downward by 8.0% from $1.10 to $1.01.
  The warrants contain provisions that require the modification of the exercise price and shares to be issued under certain circumstances, including in the event the Company completes subsequent equity financings at a price per share lower than the then-current warrant exercise price.  In addition, the warrants contain a net cash settlement provision under which the warrant holders may require the Company to purchase the warrants in exchange for a cash payment following the announcement of specified events defined as Fundamental Transactions involving the Company (e.g., merger, sale of all or substantially all assets, tender offer, or share exchange).  The net cash settlement provision requires use of the Black-Scholes model in calculating the cash payment value in the event of a Fundamental Transaction.
  - 13 -
  The fair value of the 2011 Warrants as of December 31, 2012 and March 31, 2013 was determined using a risk-neutral framework within a Monte Carlo analysis to model the impact of potential modifications to the warrant exercise price and to include the probability of a Fundamental Transaction into the calculation of fair value. The valuation of warrants is subjective and is affected by changes in inputs to the valuation model including the price per share of the Company's common stock; assumptions regarding the expected amounts and dates of future debt and equity financing activities; assumptions regarding the likelihood and timing of Fundamental Transactions and, the historical volatility of the stock prices of the Company's common stock; risk-free rates based on U.S. Treasury security yields; and the Company's dividend yield.
  In connection with the valuation performed on the 2011 Warrants, the Company believed the common stock price had not fully adjusted for the potential future dilution from the 2012 Financing due to the trading restrictions on the unregistered shares of common stock issued and issuable from the conversion of debt and warrants, the uncertainty of the Company's outcome on its research programs, and the anti-dilution adjustment features of the warrants. Therefore, the Company used an implied enterprise value considering potential future values for the Company contingent on the outcome of its research programs in conjunction with a Monte Carlo analysis to estimate the range of possible outcomes within each scenario and to allocate value to the securities in accordance with the terms of the agreements. The valuation resulted in a model-derived common stock value of $0.04 per share and $0.03 per share as of December 31, 2012 and March 31, 2013, respectively, primarily due to the preference rights of the debt holders and the anti-dilution and net cash settlement features of the 2011 and 2012 Warrants. Changes in these assumptions can materially affect the fair value estimate. The Company will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire, or are amended in a way that would no longer require these warrants to be classified as a liability.
  During the three months ended March 31, 2012 and 2013, the Company recorded non-operating income of $0.5 million and $0.3 million, respectively due to a decrease in the estimated fair value of these warrants.

  On October 2, 2012, as part of the 2012 Financing, the Company issued the 2012 Warrants to holders of the Convertible Notes.  The 2012 Warrants were exercisable at an exercise price of $0.75 per share subject to certain adjustments as specified in the warrant agreement.  The Company valued the warrants as derivative financial instruments as of the date of issuance and will continue to do so at each reporting date, with any changes in fair value being recorded on the Statement of Operations.  On April 6, 2013, the conversion price of the Convertible Notes was adjusted to $0.69 per share, the exercise price of the Warrants was adjusted to $0.69 per share, and the number of shares issuable upon exercise of the Warrants was increased to 57,438,408 shares.

  The warrants contain provisions that require the modification of the exercise price and shares to be issued under certain circumstances, including in the event the Company completes subsequent equity financings at a price per share lower than the then-current warrant exercise price.  In addition, the warrants contain a net cash settlement provision under which the warrant holders may require the Company to purchase the warrants in exchange for a cash payment following the announcement of specified events defined as Major Transactions involving the Company (e.g., merger, sale of all or substantially all assets, tender offer, or share exchange).  The net cash settlement provision requires use of the Black-Scholes model in calculating the cash payment value in the event of a Major Transaction.
  The fair value of the warrants as of December 31, 2012 and March 31, 2013 was determined using a risk-neutral framework within a Monte Carlo analysis to model the impact of potential modifications to the warrant exercise price and to include the probability of a Fundamental Transaction. In addition, the following inputs were used in the valuation model: assumptions regarding the aggregate value of the Company's debt and equity instruments, the amounts and dates of future debt financing transaction, and the historical and prospective volatility in the value of the Company's debt and equity instruments. The Company used an implied enterprise value considering potential future values for the Company contingent on the outcome of its research programs in conjunction with a Monte Carlo analysis to estimate the range of possible outcomes within each scenario and to allocate value to the securities in accordance with the terms of the agreements. The valuation resulted in a model-derived common stock value of $0.04 per share and $0.03 per share as of December 31, 2012 and March 31, 2013, respectively, primarily due to the preference rights of the debt holders and the anti-dilution and net cash settlement features of the 2011 and 2012 Warrants. Changes in these assumptions can materially affect the fair value estimate. The Company will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire, or are amended in a way that would no longer require these warrants to be classified as a liability.
  During the three months ended March 31, 2013, the Company recorded non-operating income of $0.1 million due to an increase in the estimated fair value of these warrants.

  Stock-based Compensation
  The Company currently maintains two stock-based compensation plans.  Under the 2004 Stock Option Plan (the 2004 Plan), stock awards were granted to employees, directors, and consultants of the Company, in the form of restricted stock and stock options. The amounts and terms of options granted were determined by the Company's compensation committee. The equity awards granted under the Plan generally vest over four years and have terms of up to ten years after the date of grant, and options are exercisable in cash or as otherwise determined by the board of directors. There are no shares available for future grants under the 2004 Plan, as grants from the 2004 Plan ceased upon the Company's initial public offering in April 2010.
  The 2010 Stock Incentive and Option Plan (2010 Plan) became effective upon the closing of the Company's initial public offering.  Under the 2010 Plan, stock awards may be granted to employees, directors, and consultants of the Company, in the form of restricted or unrestricted stock, stock appreciation rights, cash-based or performance share awards and stock options. The amounts and terms of options granted are determined by the Company's compensation committee. The equity awards granted under the Plan generally vest over four years and have terms of up to ten years after the date of grant, and options are exercisable in cash or as otherwise determined by the board of directors.  The 2010 Plan allows for the transfer of forfeited shares from the 2004 Plan.  As of March 31, 2013, 153,069 shares of common stock were available for future grants under the Plan.

  Subsequent Events
  On April 2, 2013, Company issued 290,935 shares of restricted common stock, to holders of the Convertible Notes to satisfy $189,000 in interest obligations due on April 2, 2013.
  On April 6, 2013, the conversion price of the Convertible Notes was adjusted to $0.69 per share, the exercise price of the 2012 Warrants was adjusted to $0.69 per share, and the number of shares issuable upon exercise of the 2012 Warrants was increased to 57,438,408 shares.  The Registration Statement filed by the Company with the SEC to register the number of 2012 Warrant shares permitted under the limitations imposed by the SEC became effective at 4:00 p.m. on March 28, 2013.  The effectiveness of the Registration Statement triggered an adjustment of the exercise price of the 2012 Warrants and the conversion price of the Convertible Notes. The volume weighted average price (the VWAP) of the Company's common stock from April 1, 2013 through April 5, 2013, the five trading days after the Registration Statement became effective (the Post-Registration Period), was $0.69, which was lower than the exercise price or conversion price for the 2012 Warrants and Convertible Notes in effect immediately prior to the expiration of the Post-Registration Period.  Pursuant to the terms of the Convertible Notes and 2012 Warrants, the exercise price and conversion price for the 2012 Warrants and Convertible Notes were adjusted to the value of the VWAP for the Post-Registration Period, and the number of shares issuable upon exercise of the 2012 Warrants was proportionately increased..

  Overview
  Tengion, Inc. is a regenerative medicine company focused on discovering, developing, manufacturing and commercializing a range of neo-organs, or products composed of living cells, with or without synthetic or natural materials, implanted or injected into the body to engraft into, regenerate, or replace a damaged tissue or organ. Using our Organ Regeneration Platform, we create these neo-organs using a patient's own cells, or autologous cells. We believe our proprietary product candidates harness the intrinsic regenerative pathways of the body to regenerate a range of native-like organs and tissues. Our product candidates are intended to delay or eliminate the need for chronic disease therapies, organ transplantation, and the administration of anti-rejection medications. In addition, our neo-organs are designed to replace the need to substitute other tissues of the body for a purpose to which they are poorly suited. Building on our clinical and preclinical experience, we are initially leveraging our Organ Regeneration Platform to develop our Neo-Urinary Conduit for bladder cancer patients who are in need of a urinary diversion and our Neo-Kidney Augment for patients with advanced chronic kidney disease.
  To date, we have devoted substantially all of our resources to the development of our Organ Regeneration Platform and product candidates, as well as to our facilities that we employ to manufacture our neo-organs. Since our inception in July 2003, we have had no revenue from product sales, and have funded our operations principally through the private and public sales of equity securities and debt financings. We have never been profitable and, as of March 31, 2013, we had an accumulated deficit of $252.9 million, including $48.4 million of cumulative accretion on the Redeemable Convertible Preferred Stock through April 2010. We expect to continue to incur significant operating losses for the foreseeable future as we advance our product candidates from discovery through preclinical studies and clinical trials and seek marketing approval and eventual commercialization.
  - 18 -
  Cash and cash equivalents at March 31, 2013 were $2.9 million, representing 38% of total assets. Based upon our current expected level of operating expenditures and debt repayment, and assuming we are not required to settle any outstanding warrants in cash or redeem, or pay cash interest on, any of our Convertible Notes, we expect to be able to fund operations through May 2013. We will need to raise more funds to complete the Phase I clinical trial for our Neo-Urinary Conduit and continue preclinical research and development activities for our Neo-Kidney Augment. There is no assurance that such financing will be available or, if available, on terms acceptable to us.
  Financial Operations Overview
  Research and Development Expense
  Our research and development expense consists of expenses incurred in developing and testing our product candidates and are expensed as incurred. Research and development expense include:
  ·
  personnel related expenses, including salaries, benefits, travel and other related expenses including stock-based compensation;
  ·
  payments made to third-party contract research organizations for preclinical studies, investigative sites for clinical trials and consultants;
  ·
  costs associated with regulatory filings and the advancement of our product candidates through preclinical studies and clinical trials;
  ·
  laboratory and other supplies;
  ·
  manufacturing development costs; and
  ·
  facility maintenance.
  Preclinical study and clinical trial costs for our product candidates are a significant component of our current research and development expenses. We track and record information regarding external research and development expenses on a per-study basis. Preclinical studies are currently coordinated with third-party contract research organizations and expense is recognized based on the percentage completed by study at the end of each reporting period. Clinical trials are currently coordinated through a number of contracted sites and expense is recognized based on a number of factors, including actual and estimated patient enrollment and visits, direct pass-through costs and other clinical site fees. We utilize internal employees, resources and facilities across multiple product candidates.  We do not allocate internal research and development expenses among product candidates.
  The following table summarizes our research and development expense for the three months ended March 31, 2012 and 2013 (in thousands):

  From our inception in July 2003 through March 31, 2013, we have incurred research and development expense of $130.1 million. We expect that a large percentage of our research and development expense in the future will be incurred in support of our current and future preclinical and clinical development programs. These expenditures are subject to numerous uncertainties in timing and cost to completion. We expect to continue to test our product candidates in preclinical studies for toxicology, safety and efficacy, and to conduct additional clinical trials for each product candidate. If we are not able to engage a partner prior to the commencement of later stage clinical trials, we may fund these trials ourselves. As we obtain results from clinical trials, we may elect to discontinue or delay clinical trials for certain product candidates or programs in order to focus our resources on more promising product candidates or programs. Completion of clinical trials by us or our future collaborators may take several years or more, but the length of time generally varies according to the type, complexity, novelty and intended use of a product candidate. The cost of clinical trials may vary significantly over the life of a project as a result of differences arising during clinical development, including, among others:
  - 19 -
  ·
  the number of sites included in the trials;
  ·
  the length of time required to enroll suitable patients;
  ·
  the number of patients that participate in the trials;
  ·
  the duration of patient follow-up;
  ·
  the development stage of the product candidate; and
  ·
  the efficacy and safety profile of the product candidate.
  None of our product candidates have received FDA or foreign regulatory marketing approval. In order to grant marketing approval, the FDA or foreign regulatory agencies must conclude that clinical data establishes the safety and efficacy of our product candidates. Furthermore, our strategy includes entering into collaborations with third parties to participate in the development and commercialization of our product candidates. In the event that third parties have control over the clinical trial process for a product candidate, the estimated completion date would largely be under control of that third party rather than under our control. We cannot forecast with any degree of certainty which of our product candidates will be subject to future collaborations or how such arrangements would affect our development plan or capital requirements.
  As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our development projects or when and to what extent we will receive cash inflows from the commercialization and sale of an approved product candidate.
  Critical Accounting Policies and Use of Estimates
  The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make significant judgments and estimates 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 bases these significant judgments and estimates on historical experience and other assumptions it believes to be reasonable based upon information presently available. Actual results could differ from those estimates under different assumptions, judgments or conditions. There were no material changes to our critical accounting policies and use of estimates previously disclosed in our 2012 Annual Report on Form 10-K.

  Research and development expense were $2.7 million and $2.2 million for the three months ended March 31, 2012 and 2013, respectively. The decrease in research and development expense for the three months ended March 31, 2013 was primarily due to a reduction in compensation and related expenses resulting from fewer employees as compared to the three months ended March 31, 2012, as well as a reduction in external services related to the submission of a Pre-IND filing with the FDA for the Neo-Kidney Augment in March 2012.

  General and administrative expense was $1.4 million and $1.9 million for the three months ended March 31, 2012 and 2013, respectively. The increase in general and administrative expense for the three months ended March 31, 2013 was primarily due to an increase in legal fees resulting from a change in corporate counsel as well as significant registration statement activity during 2013 related to securities issued in our 2011 and 2012 financings.
  Depreciation Expense.
  Depreciation expense was $136,000 and $83,000 for the three months ended March 31, 2012 and 2013, respectively. The decrease in depreciation expense is solely due to an increased number of fully depreciated assets in 2013.
  Other Expense.
  Other expense was $48,000 and $30,000 for the three months ended March 31, 2012 and 2013, respectively.
  Interest Income (Expense).
  Interest income was $7,000 and $5,000 for the three months ended March 31, 2012 and 2013, respectively. Interest expense was $0.2 million and $1.4 million for the three months ended March 31, 2012 and 2013, respectively. The increase was primarily due to non-cash interest expense associated with the Convertible Notes issued in the fourth quarter of 2012.
  Change in Fair Value of Derivative Liability.
  During the three months ended March 31, 2013, we recorded a non-cash charge of $0.3 million on our statements of operations due to a change in the fair value of the derivative liability for the Conversion Option and the Call Option.
  Change in Fair Value of Warrant Liability.
  During the three months ended March 31, 2013, we recorded a non-cash credit of $0.1 million on our statements of operations due to a change in the fair value of the warrant liability for warrants to purchase common stock that were issued in March 2011 and October 2012. The decrease in fair value is due to the passage of time. During the three months ended March 31, 2012, we recorded a non-cash credit of $0.5 million on our statement of operations due to a decrease in the fair value of the warrant liability for warrants to purchase common stock that were issued in March 2011. The decrease in fair value was primarily due to a decrease in the price per share of our common stock.
  Liquidity and Capital Resources
  Source of Liquidity
  We have incurred losses since our incorporation in 2003 as a result of our significant research and development expenditures and the lack of any approved products to generate product sales. We have a deficit accumulated during the development stage of $252.9 million as of March 31, 2013, including $48.4 million of cumulative accretion on Redeemable Convertible Preferred Stock through April 2010. We anticipate that we will continue to incur additional losses until such time that we can generate significant sales of our product candidates currently in development or we enter into cash flow positive business transactions. We have funded our operations principally with proceeds from equity and debt offerings.
  Cash and cash equivalents at March 31, 2013, were $2.9 million, representing 38% of total assets.   Based upon our current expected level of operating expenditures and debt repayment, and assuming we are not required to settle any outstanding warrants in cash or redeem, or pay cash interest on, any of our Convertible Notes, we expect to be able to fund operations through May 2013.  This period could be shortened if there are any significant increases in planned spending on development programs than anticipated or other unforeseen events. We will need to raise additional funds through collaborative arrangements, public or private sales of debt or equity securities, commercial loan facilities, or some combination thereof. There is no assurance that other financing will be available when needed to allow us to continue our operations or if available, on terms acceptable to us.

  Cash used in operating activities decreased $1.2 million for the three months ended March 31, 2013, compared to the three months ended March 31, 2012, primarily due to the payment of $1.0 million security deposit in 2012.
  Investing Activities
  Cash provided by investing activities decreased $4.5 million for the three months ended March 31, 2013, compared to the three months ended March 31, 2012, primarily due to an increase in net sales and redemptions (net of purchases) of short-term investments of $4.5 million.
  Financing Activities
  Cash provided by financing activities increased $0.6 million for the three months ended March 31, 2013, compared to the three months ended March 31, 2012 due to debt payments in the 2012 period.

  Item 3.                      Quantitative and Qualitative Disclosures About Market Risk.
  There have been no material changes in the market risks discussed in Part II, Item 7A "Quantitative and Qualitative Disclosures about Market Risk"  included in our Annual Report on Form 10-K.
  Item 4.                      Controls and Procedures.
  Evaluation of Disclosure Controls and Procedures and Changes in Internal Control over Financial Reporting
  As required by Rule 13a-15 under the Exchange Act, as of the end of the period covered by this report, the Company carried out an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures. This evaluation was carried out under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer. The Company had previously reported a material weakness in internal control over financial reporting with respect to the misapplication of U.S. Generally Accepted Accounting Principles for the classification of debt financing costs. which was described in Item 9A including Management's Annual Report on Internal Control Over Financial Reporting in the Company's Annual Report on Form 10-K for the year ended December 31, 2012. This material weakness was the result of limited accounting and reporting resources and a lack of accounting expertise related to the initial classification of debt financing costs incurred for convertible debt issuances that include issuance of derivatives such as warrants and call options. This material weakness did not have an impact on our financial statements for the year ended December 31, 2012 as we made the appropriate correcting journal entries.  As a result of this material weakness in the Company's internal control over financial reporting related to the accounting for significant financing transactions, which was not remediated as of March 31, 2013, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were not effective as of March 31, 2013.
  Disclosure controls and procedures are designed to ensure that information required to be disclosed in Company reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in Company reports filed under the Exchange Act is accumulated and communicated to management, including the Company's Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.
  The Company has continued to implement remediation steps to address the material weakness discussed above and to improve its internal control over accounting for significant financing transactions. Specifically, the Company has developed supplemental internal control procedures to properly evaluate the accounting implications of significant financing transactions and has identified qualified resources to execute the process and procedural enhancements.
  The measures described above should remediate the material weakness identified and strengthen our internal controls over the accounting for significant financing transactions. Management is committed to improving the Company's internal control processes. As the Company continues to evaluate and improve its internal control over accounting for significant financing transactions, additional measures to address the material weakness or modifications to certain of the remediation procedures described above may be identified. The Company expects to complete the required remedial actions during 2013.
  Other than as described above, there was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
