At the Closing, on the terms and subject to the conditions set forth in this Agreement, the Company is issuing and selling to each Investor, and each Investor is purchasing, severally and not jointly, from the Company (collectively, the sales of all of the Purchased Securities hereunder, the “Purchase”) (a) the number of shares of Common Stock set forth opposite such Investor’s name on Schedule 1.1, for a purchase price of $1.95 per share of Common Stock (which the parties hereto agree is the consolidated closing bid price per share of Common Stock as of the business day immediately prior to the date hereof) and (b) the number of Series A Shares and Warrants exercisable for the number of Warrant Shares in each case set forth opposite such Investor’s name on Schedule 1.1, for an aggregate purchase price of $10,000 per Series A Share (including the related Warrants), for an aggregate purchase price of $12,000,000, by wire transfer of immediately available funds to a bank account designated by the Company. Before September 30, 2012, the Company and the Investors shall mutually agree on the allocation of such aggregate purchase price, less the portion for the Purchased Common Shares, to the Series A Shares and the Warrants; provided that the price per Warrant Share of the Warrants shall be no less than $0.125 per share.

The authorized capital stock of the Company consists of 100,000,000 shares of Common Stock, of which 12,407,702 shares are issued and outstanding, and 5,000,000 shares of Preferred Stock, of which 6,000 shares of Series A Cumulative Redeemable Preferred Stock are issued or outstanding and 236,230.99 shares of Series B Voting Preferred Stock are issued and outstanding. Schedule 3.1(b) sets forth all of the options,

warrants and equity incentive plans of the Company, and the number of shares of Common Stock reserved for issuance pursuant to any outstanding options, warrants or equity incentive plans. The outstanding shares of the Company’s capital stock have been duly authorized and are validly issued and outstanding, fully paid and non-assessable, are not subject to preemptive rights (and were not issued in violation of any preemptive rights) and were issued in full compliance with applicable state and federal securities laws and any rights of third parties. Except as provided in the 2010 Purchase Agreement, no person is entitled to preemptive or similar statutory or contractual rights with respect to any securities of the Company. Except as set forth above or on Schedule 3.1(b), there are no outstanding warrants, options, convertible securities or other rights, agreements or arrangements of any character under which the Company or any of its Subsidiaries is or may be obligated to issue any equity securities of any kind and, except as contemplated by this Agreement, neither the Company nor any of its Subsidiaries is currently in negotiations for the issuance of any equity securities of any kind. The issuance and sale of the Purchased Securities hereunder will not obligate the Company to issue shares of Common Stock or other securities to any other person (other than the Investors) and will not result in the adjustment of the exercise, conversion, exchange or reset price of any outstanding security.

(c) Purchased Common Shares and Series A Shares. The Purchased Common Shares and the Series A Shares have been duly and validly authorized, and, when issued and delivered pursuant to this Agreement, the Purchased Common Shares and the Series A Shares will be duly and validly issued, fully paid and non-assessable.

(d) Warrants and Warrant Shares. The Warrants (including any Warrants issued pursuant to Section 1.4) have been duly authorized and, when executed and delivered as contemplated hereby, will constitute a valid and legally binding obligation of the Company in accordance with their terms, and the shares of Common Stock issuable upon exercise of the Warrants (including Warrants issuable pursuant to Section 1.4) (the “Warrant Shares”) have been duly authorized and reserved for issuance upon exercise of the Warrants and when issued will be duly and validly issued, fully paid and non-assessable.

(e) Authorization, Enforceability.

(i) The Company has the corporate power and authority to execute and deliver the Transaction Documents and to carry out its obligations hereunder (which includes the issuance of the Purchased Securities and the Warrant Shares) and thereunder. The execution, delivery and performance by the Company of the Transaction Documents and the consummation of the Transactions have been duly authorized by all necessary corporate action on the part of the Company, and no further approval or authorization is required on the part of the Company. The Transaction Documents are or will be valid and binding obligations of the Company enforceable against the Company in accordance with their respective terms, except as the same may be limited by applicable bankruptcy, insolvency, reorganization, fraudulent transfer or conveyance, moratorium or similar laws affecting the enforcement of creditors’ rights generally and general equitable principles, regardless of whether such enforceability is considered in a proceeding at law or in equity (“Bankruptcy Exceptions”).

(ii) Except as set forth on Schedule 3.1(e), the execution, delivery and performance by the Company of the Transaction Documents, compliance by the Company with any of the provisions hereof or thereof and the consummation of the Transactions, will not (i) violate, conflict with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination of, accelerate the performance required by, or result in any payment obligations under, or result in a right of termination, acceleration or payment of, or result in the creation of, any lien, security interest, charge or encumbrance upon any of the properties or assets of the Company or any of its Subsidiaries under any of the terms, conditions or provisions of (A) the Certificate of Incorporation or by-laws of the Company or (B) any material note, bond, mortgage, indenture, deed of trust, license, lease, agreement or other instrument or obligation to which the Company or any of its Subsidiaries is a party or by which it or any of its Subsidiaries may be bound, or to which the Company or any of its Subsidiaries or any of the properties or assets of the Company or any of its Subsidiaries may be subject, including as a result of any change of control or similar provision (except for violations, conflicts, breaches or defaults that would not be reasonably likely to be material to the Company and its Subsidiaries, taken as a whole) or (ii) subject to compliance with the statutes and regulations referred to in the next paragraph, materially violate (x) any statute, rule or regulation or any judgment, ruling, order, writ, injunction or decree or (y) any rule related to the qualification, listing and delisting of companies on the Nasdaq Stock Market, in each case applicable to the Company or any of its Subsidiaries or any of their respective properties or assets.

(f) Other than the filing of any current report on Form 8-K and a Form D required to be filed with the Securities and Exchange Commission, and such as have been made or obtained, no notice to, filing with, exemption or review by, or authorization, consent or approval of, any Governmental Entity is required to be made or obtained by the Company in connection with the consummation of the Transactions.

(g) Brokers or Finders. The Company represents as to itself, its predecessors and its Affiliates, that no agent, broker, investment banker or other firm or person is or will be entitled to any broker’s or finder’s fee or any other commission or similar fee in connection with the Purchase.

Neither the Company nor any person acting on its behalf has conducted any general solicitation or general advertising (as those terms are used in Regulation D of the Securities Act) in connection with the offer or sale of any of the Purchased Securities.

(i) No Integrated Offering. Neither the Company nor any of its Affiliates, nor any person acting on its or their behalf has, directly or indirectly, made any offers or sales of any Company security or solicited any offers to buy any security, under circumstances that would adversely affect reliance by the Company on Section 4(2) of the Securities Act for the exemption from registration for the transactions contemplated hereby or would require registration of the Purchased Securities under the Securities Act.

3.2 Representations and Warranties of the Investors. The Investors, jointly and severally, hereby represent and warrant to the Company that as of the date hereof:

This Agreement and the Registration Rights Amendment are or will be valid and binding obligations of each Investor enforceable against such Investor in accordance with their respective terms, except as the same may be limited by Bankruptcy Exceptions.

(ii) The execution, delivery and performance by each Investor of this Agreement and the Registration Rights Amendment and the consummation of the transactions contemplated hereby and thereby and compliance by such Investor with any of the provisions hereof and thereof, will not (i) violate, conflict with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination of, or accelerate the performance required by, or result in a right of termination or acceleration of, or result in the creation of, any lien, security interest, charge or encumbrance upon any of the properties or assets of such Investor under any of the terms, conditions or provisions of (A) its organizational documents or (B) any note, bond, mortgage, indenture, deed of trust, license, lease, agreement or other instrument or obligation to which such Investor is a party or by which it may be bound, or to which such Investor or any of the properties or assets of such Investor may be subject, or (ii) violate any statute, rule or regulation or any judgment, ruling, order, writ, injunction or decree applicable to such Investor or any of its properties or assets.

(iii) Other than such as have been made or obtained, no notice to, filing with, exemption or review by, or authorization, consent or approval of, any Governmental Entity is required to be made or obtained by any Investor in connection with the consummation by such Investor of the Purchase.

(c) Purchase for Investment. Each Investor acknowledges that the offering and sale of the Purchased Securities and the Warrant Shares have not been registered under the Securities Act or under any state securities laws.

Purchased Securities or the Warrant Shares, except in compliance with the registration requirements or exemption provisions of the Securities Act and any applicable U.S. state securities laws, (iii) has such knowledge and experience in financial and business matters and in investments of this type that it is capable of evaluating the merits and risks of the Purchase and of making an informed investment decision, and has conducted a review of the business and affairs of the Company that it considers sufficient and reasonable for purposes of making the Purchase, and (iv) is an “accredited investor” (as that term is defined by Rule 501 under the Securities Act).

(d) Company Representations. Each of the Investors acknowledges and agrees that (1) other than as expressly set forth in Section 3.1 hereof, neither the Company nor any of its directors, officers, shareholders, employees, Affiliates, agents, advisors or representatives (collectively, “Representatives”) is making or has made any representations or warranties, written or oral, statutory, express or implied, concerning the Company, its Subsidiaries, their respective businesses or assets or any aspect of the Transactions and (2) such Investor has not been induced by and has not relied upon any representations, warranties or statements, whether written or oral, statutory, express or implied, made by the Company or any of its Representatives that are not expressly set forth in Section 3.1 hereof.

ARTICLE IV

Covenants and Additional Agreements

4.1 Further Assurances. At any time and from time to time after the Closing, at the request of any Investor, the Company shall execute and deliver such further documents, and perform such further acts, as may be reasonably necessary in order to effectively transfer and convey the applicable Purchased Securities and the Warrant Shares to each of the Investors, on the terms herein contained, and to otherwise comply with the terms of this Agreement and consummate the Transactions.

4.2 Expenses.

(a) At any time and from time to time after the Closing, the Company shall reimburse the Investors for their reasonable costs and expenses, including reasonable legal or other professional fees and expenses, and reasonable out-of-pocket due diligence expenses, incurred or made (i) in connection with this Agreement and the Transactions (including any reasonable cost and expenses incurred after the Closing to the extent related) and (ii) in connection with any amendments to the Transaction Documents. Prior to any such reimbursement, the Investors shall provide the Company with reasonably detailed invoices setting forth the expenses to be reimbursed and, within 30 days thereof, the Company shall pay the applicable amount by a wire transfer of immediately available funds as designated by the Investors.

(b) The Company shall reimburse the Investors for their reasonable out-of-pocket costs and expenses (including airfare, hotels and cab fare) incurred or made in connection with ongoing oversight of the Company during the period commencing on the date hereof and ending the later of (i) the first anniversary of the Closing Date and (ii) the first date on which the Investors, on the one hand, or the Independent Majority, on the other hand, provide good faith

written notice to the other that the Investors’ ongoing oversight of the Company has ceased to provide sufficient value to the stockholders of the Company to justify such reimbursement. Prior to any such reimbursement, the Investors shall provide the Company with reasonably detailed invoices setting forth the expenses to be reimbursed and a good faith attestation that such costs were incurred in the course of conducting work for the benefit of all Company shareholders. Reimbursements shall be made within 30 days of the invoices having been presented to the Company.

4.3 Transfer Restrictions. The Purchased Securities are, and the Warrant Shares will be when issued, restricted securities under the Securities Act and may not be offered or sold except pursuant to an effective registration statement or an available exemption from registration under the Securities Act. Accordingly, each Investor agrees it shall not, directly or through others, offer or sell any Purchased Securities or any Warrant Shares except pursuant to a registration statement or pursuant to Rule 144 or another exemption from registration under the Securities Act, if available. Prior to any transfer of Purchased Securities or Warrant Shares other than pursuant to an effective registration statement, each Investor agrees it shall notify the Company of such transfer and the Company may require such Investor to provide, prior to such transfer, such evidence that the transfer will comply with the Securities Act (including written representations and an opinion of counsel) as the Company may reasonably request. The Company may impose stop-transfer instructions with respect to any securities that are to be transferred in contravention of this Agreement.

4.4 Legend. Each Investor agrees that all certificates or other instruments representing Purchased Securities or Warrant Shares will bear a legend substantially to the following effect:

“THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A REGISTRATION STATEMENT RELATING THERETO IS IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS. THIS INSTRUMENT IS ISSUED PURSUANT TO AND SUBJECT TO THE RESTRICTIONS ON TRANSFER AND OTHER PROVISIONS OF THE SECURITIES PURCHASE AGREEMENT, DATED AUGUST 1, 2012, AS AMENDED FROM TIME TO TIME, AMONG THE ISSUER OF THESE SECURITIES AND THE INVESTORS REFERRED TO THEREIN, A COPY OF WHICH IS ON FILE WITH THE ISSUER. THE SECURITIES REPRESENTED BY THIS INSTRUMENT MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT IN COMPLIANCE WITH SAID AGREEMENT. ANY SALE OR OTHER TRANSFER NOT IN COMPLIANCE WITH SAID AGREEMENT WILL BE VOID.”

In the event that (i) any Purchased Securities or Warrant Shares become registered under the Securities Act or (ii) Purchased Securities or Warrant Shares are eligible to be transferred without restriction in accordance with Rule 144 under the Securities Act, the Company shall issue new certificates or other instruments representing such Purchased Securities or Warrant Shares, which shall not contain such portion of the above legend that is no longer applicable; provided that the Investors surrender to the Company the previously issued certificates or other instruments.

4.5 Sufficiency of Authorized Common Stock. During the period from the Closing Date until the date on which the Warrants (including any Warrants issuable pursuant to Section 1.4) have been fully exercised, the Company shall at all times have reserved for issuance, free of preemptive or similar rights, a sufficient number of shares of authorized and unissued Warrant Shares to effectuate such exercise (including all Warrant Shares underlying the Warrants issuable pursuant to Section 1.4). Nothing in this Section 4.5 shall preclude the Company from satisfying its obligations in respect of the exercise of the Warrants (including any Warrants issuable pursuant to Section 1.4) by delivery of shares of Common Stock which are held in the treasury of the Company. As soon as practicable following the Closing, the Company shall, at its expense, (a) cause the Warrant Shares (including all Warrant Shares underlying the Warrants issuable pursuant to Section 1.4) to be listed on the NASDAQ Global Market at the time they become freely transferable in the public market under the Securities Act, subject to official notice of issuance, and shall maintain such listing on the NASDAQ Global Market for so long as any Common Stock is listed on the NASDAQ Global Market and (b) use its commercially reasonable efforts to satisfy all continued listing criteria necessary to maintain the listing of the Common Stock with NASDAQ until the date that is two years following the date on which the Warrants (including any Warrants issuable pursuant to Section 1.4) have been fully exercised.

4.6 Indemnification.

(a) Indemnification by the Company. From and after the Closing, the Company shall indemnify and hold harmless the Investors and their respective Affiliates and their respective directors, officers, employees and agents (the “Investor Indemnified Parties”) from and against any and all losses, claims, damages, liabilities and expenses (including without limitation reasonable attorney fees and disbursements and other expenses reasonably incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) (collectively, “Losses”) asserted against or incurred by such Investor Indemnified Party to the extent arising out of or in connection with (i) any breach of the representations or warranties of the Company set forth in this Agreement or (ii) any breach or violation of the covenants or agreements of the Company set forth in this Agreement.

(b) Indemnification by the Purchasers. From and after the Closing, each of the Investors shall, severally but not jointly, indemnify and hold the Company harmless from and against all Losses asserted against or incurred by the Company to the extent arising out of or in connection with (i) any breach of the representations or warranties of such Investor set forth in this Agreement or (ii) any breach or violation of the covenants or agreements of such Investor set forth in this Agreement.

(c) No Duplication. Any liability for indemnification under this Agreement shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach or violation of more than one representation, warranty, covenant or agreement.

(d) Sole Remedy. The parties agree that the sole and exclusive remedy of any party to this Agreement or any Investor Indemnified Parties, the events giving rise to this Agreement and the transactions provided for in this Agreement (excluding, for the avoidance of doubt, the transactions provided for in the Registration Rights Amendment), shall be limited to the indemnification provisions set forth in this Section 4.6 and, in furtherance of the foregoing, each of the parties, on behalf of itself and its Affiliates, waives and releases the other parties to this Agreement (and such other parties’ Affiliates) from, to the fullest extent permitted under any applicable law, any and all rights, claims and causes of action it or its Affiliates may have against the other parties to this Agreement in connection with the events giving rise to this Agreement and the transactions provided for in this Agreement (excluding, for the avoidance of doubt, the transactions provided for in the Registration Rights Amendment), except pursuant to the indemnification provisions set forth in this Section 4.6; provided, however, that nothing herein shall limit in any way any such party’s remedies in respect of fraud, intentional misrepresentation or omission or intentional misconduct by the other parties in connection herewith or the Transactions.

(e) NO SPECIAL DAMAGES. IN NO EVENT SHALL ANY PARTY BE LIABLE UNDER THIS SECTION 4.6 OR OTHERWISE IN RESPECT OF THIS AGREEMENT (EXCLUDING, FOR THE AVOIDANCE OF DOUBT, THE REGISTRATION RIGHTS AMENDMENT) FOR EXEMPLARY, SPECIAL, PUNITIVE, INDIRECT, REMOTE, SPECULATIVE OR CONSEQUENTIAL DAMAGES EXCEPT TO THE EXTENT ANY SUCH PARTY SUFFERS SUCH DAMAGES TO AN UNAFFILIATED THIRD PARTY IN CONNECTION WITH A LOSS, IN WHICH EVENT SUCH DAMAGES SHALL BE RECOVERABLE; PROVIDED, HOWEVER, THAT THE INVESTOR INDEMNIFIED PARTIES SHALL BE ENTITLED TO RECOVER FROM THE COMPANY ANY AMOUNTS FOR LOSSES TO THE EXTENT NECESSARY TO COMPENSATE THE INVESTOR INDEMNIFIED PARTIES IN FULL FOR THE DIMINUTION IN VALUE OF ITS INVESTMENT IN THE COMPANY IF SUCH LOSSES RESULT FROM AN INDEMNIFIABLE CLAIM COVERED BY SECTION 4.6(a).

4.7 Restrictions on Sale of Common Stock. Each of the Investors agrees that the Purchased Securities and the Warrant Shares (including all Warrant Shares underlying the Warrants issuable pursuant to Section 1.4) shall be “Excluded Securities” as defined in, and for purposes of, the 2010 Purchase Agreement.

Section 4. Dividends.

(a) Rate. Holders of Series A shall be entitled to receive, on each share of Series A, out of funds legally available for the payment of dividends under Delaware law, cumulative cash dividends at a per annum rate of 12% on the Liquidation Preference. Such dividends shall begin to accrue and be cumulative from the Original Issue Date of such share, shall compound on each Dividend Payment Date (i.e., no dividends shall accrue on other dividends unless and until the first Dividend Payment Date for such other dividends has passed without such other dividends having been paid on such date), and shall be payable in arrears (as provided in this Section 4(a)). Through December 31, 2014, dividends shall be payable only when, as and if declared by the Board of Directors. Thereafter, the Board of Directors shall declare dividends, payable on each Dividend Payment Date, subject only to the legal availability of funds for declaration and payment thereof. If any such Dividend Payment Date would otherwise occur on a day that is not a Business Day, such Dividend Payment Date shall instead be (and any dividend payable on Series A on such Dividend Payment Date shall instead be payable on) the immediately succeeding Business Day with the same force and effect as if made on such Dividend Payment Date. The amount of dividends payable on the Series A shall be computed on the basis of a 360-day year consisting of twelve 30-day months, and with respect to any date of determination that is not a Dividend Payment Date, actual days elapsed over a 30-day month.

Dividends that are payable on Series A on any Dividend Payment Date shall be payable to holders of record of Series A as they appear on the stock register of the Corporation on the applicable record date, which shall be the 15th calendar day before such Dividend Payment Date (as originally scheduled) or such other record date fixed by the Board of Directors that is not more than 60 nor less than 10 days prior to such Dividend Payment Date (each, a “Dividend Record Date”). Any such day that is a Dividend Record Date shall be a Dividend Record Date whether or not such day is a Business Day.

Each dividend period (a “Dividend Period”) shall commence on the calendar day immediately following a Dividend Payment Date (other than the initial Dividend Period with respect to any share of Series A, which shall commence on and include the Original Issue Date of such share) and shall end on and include the next Dividend Payment Date. Dividends payable in respect of a Dividend Period shall be payable in arrears on the Dividend Payment Date ending such Dividend Period.

(b) Priority of Dividends. When dividends are not paid (or declared and a sum sufficient for payment thereof set aside for the benefit of the holders thereof on the applicable Dividend Record Date) on any Dividend Payment Date in full upon the Series A, all dividends declared on the Series A and payable on such Dividend Payment Date shall be declared pro rata so that the respective amounts of such dividends declared shall bear the same ratio to each other as all accrued and unpaid dividends per share on the Series A (including, if applicable as provided in Section 4(a) above, dividends on such amount) bear to each other.

Section 5. Liquidation Rights.

(a) Voluntary or Involuntary Liquidation. In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, holders of Series A shall be entitled to receive for each share of Series A, out of the assets of the Corporation or proceeds thereof (whether capital or surplus) available for distribution to stockholders of the Corporation, and after satisfaction of all liabilities and obligations to creditors of the Corporation, before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other Junior Stock, payment in full in an amount equal to the Liquidation Preference of such share.

(b) Partial Payment. If in any distribution described in Section 5(a) above, the assets of the Corporation or proceeds thereof are not sufficient to pay the Liquidation Preferences in full to all holders of Series A as to such distribution, the amounts paid to the holders of Series A shall be paid pro rata in accordance with the respective aggregate Liquidation Preferences of the holders of Series A.

(c) Residual Distributions. If the Liquidation Preference has been paid in full to all holders of Series A, the holders of other stock of the Corporation shall be entitled to receive all remaining assets of the Corporation (or proceeds thereof) according to their respective rights and preferences.

(d) Merger, Consolidation and Sale of Assets Not Liquidation. For purposes of this Section 5, the merger or consolidation of the Corporation with any other corporation or other entity, including a merger or consolidation in which the holders of Series A receive cash, securities or other property for their shares, or the sale, lease or exchange (for cash, securities or other property) of all or substantially all of the assets of the Corporation, shall not constitute a liquidation, dissolution or winding up of the Corporation, but shall be governed by Section 7.

Section 6. Redemption.

(a) Mandatory Redemption. On March 21, 2018, the Corporation shall redeem, in whole, the shares of Series A at the time outstanding, upon notice given as provided in Section 6(c) below, at a redemption price per share equal to 100% of the Liquidation Preference of such share as of the redemption date. The redemption price for any shares of Series A shall be payable on the redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to the Corporation or its agent.

(b) Optional Redemption. From and after one year from the Original Issue Date until March 21, 2018, the Corporation, at its option, may redeem, in whole at any time or in part from time to time, the shares of Series A at the time outstanding, upon notice given as provided in Section 6(c) below, at a redemption price per share equal to 110% of the Liquidation Preference of such share as of the redemption date, provided that the minimum number of shares of Series A redeemable at any time is the lesser of (i) 500 shares of Series A and (ii) the number of shares of Series A outstanding. The redemption price for any shares of Series A shall be payable on the redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to the Corporation or its agent.

(c) Notice of Redemption. Notice of every redemption of shares of Series A shall be given to the holders of record of the shares to be redeemed at their respective last addresses appearing on the books of the Corporation. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this Subsection shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of shares of Series A designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Series A. Each notice of redemption given to a holder shall state: (1) the redemption date; (2) the number of shares of Series A to be redeemed and, if less than all the shares held by such holder are to be redeemed, the number of such shares to be redeemed from such holder; (3) the redemption price; and (4) the place or places where certificates for such shares are to be surrendered for payment of the redemption price.

(d) Partial Redemption. In case of any redemption of part of the shares of Series A at the time outstanding, the shares to be redeemed shall be selected pro rata among holders of the Series A. If fewer than all the shares represented by any certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without charge to the holder thereof.

(e) Effectiveness of Redemption. If notice of redemption has been duly given and if on or before the redemption date specified in the notice all funds necessary for the redemption have been deposited by the Corporation, in trust for the pro rata benefit of the holders of the shares called for redemption, with a bank or trust company doing business in the Borough of Manhattan, The City of New York, and having a capital and surplus of at least $500 million and selected by the Board of Directors, so as to be and continue to be available solely therefor, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation, on and after the redemption date dividends shall cease to accrue on

all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption from such bank or trust company, without interest. Any funds unclaimed at the end of three years from the redemption date shall, to the extent permitted by law, be released to the Corporation, after which time the holders of the shares so called for redemption shall look only to the Corporation for payment of the redemption price of such shares.

Section 7. Offer to Purchase Upon a Change of Control.

(a) In connection with the occurrence of a Change of Control, the Corporation shall make an offer to purchase all of the shares of Series A outstanding (a “Change of Control Offer”) on the terms set forth in this Section 7. The Change of Control Offer shall be made in compliance with all applicable laws, including, without limitation (if applicable), Regulation 14E and 14D under the Exchange Act and the rules thereunder and all other applicable Federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 7, the Corporation shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 7 by virtue thereof.

(b) No sooner than fifteen (15) days and within that time period, as soon as reasonably practicable, prior to the consummation, or anticipated consummation, of a Change of Control, the Corporation shall commence the Change of Control Offer by mailing to each holder of shares of Series A a notice, which shall govern the terms of the Change of Control Offer, and shall state:

(i) that the Change of Control Offer is being made pursuant to this Section 7 and that all shares of Series A tendered will be accepted for payment subject to the consummation of the Change of Control;

(ii) the Change of Control Price (as defined below) and the date until which the Corporation may accept for payment shares of Series A (the “Change of Control Payment Date”), which shall be (subject to consummation of the Change of Control) no later than forty-five (45) days after the date the Change of Control occurs;

(iii) that any shares of Series A not tendered for payment pursuant to the Change of Control Offer shall continue to accrue dividends and be redeemable in accordance with the terms hereof;

(iv) that, unless the Corporation defaults in the payment of the Change of Control Price, all shares of Series A accepted for payment pursuant to the Change of Control Offer shall cease to accrue dividends on the Change of Control Payment Date;

(v) that any holder electing to have certificates representing shares of Series A pursuant to a Change of Control Offer shall be required to surrender such certificates representing shares of Series A to the Corporation or its designated agent at the address specified in the notice prior to the close of business on the Change of Control Payment Date;

(vii) that a holder whose shares of Series A are being purchased only in part shall be issued new shares of Series A for the unpurchased shares of Series A represented by any certificate surrendered;

(viii) the instructions that holders must follow in order to tender their shares of Series A; and

(ix) the circumstances and relevant facts regarding such Change of Control.

(c) On the Change of Control Payment Date, the Corporation shall, to the extent of funds legally available therefore and otherwise lawful, accept for payment the shares of Series A tendered and not withdrawn pursuant to the Change of Control Offer. The Corporation shall promptly mail to each holder of shares of Series A so accepted payment (or pay in person any holder presenting itself at the Corporation) in an amount equal to the purchase price for such shares, and the unpurchased shares of Series A surrendered, if any.

(d) The Corporation shall make a public announcement of the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(e) The Corporation shall not enter into any agreement providing for a Change of Control unless the agreement permits the Corporation or any successor entity to comply with the provisions hereof.

(f) “Change of Control Price” means an amount of cash per share of Series A equal to 110% of the Liquidation Price of such share as of the date of acceptance for payment.

Section 8. Conversion. Holders of Series A shares shall have no right to exchange or convert such shares into any other securities.

(a) General. The holders of Series A shall not have any voting rights except as set forth below or as otherwise from time to time required by law.

(A) Any amendment, alteration or repeal of any provision of the Certificate of Incorporation so as to change the rights, preferences, privileges or voting powers of the Series A;

3. Exercise of Warrant; Term.

(a) The right to purchase the Shares represented by this Warrant is exercisable, in whole or in part by the Warrantholder, at any time or from time to time after the Effective Date and after the receipt of all applicable Regulatory Approvals, but in no event later than 5:00 p.m., New York City time, on the date that is ninety (90) months after the Issue Date (the “Expiration Time”), by (A) the surrender of this Warrant and Notice of Exercise annexed hereto, duly completed and executed on behalf of the Warrantholder, at the principal executive office of the Corporation located at 210 Park Avenue, Suite 2750, Oklahoma City, OK 73102 (or such other office or agency of the Corporation in the United States as it may designate by notice in writing to the Warrantholder at the address of the Warrantholder appearing on the books of the

Corporation), and (B) payment of the Exercise Price for the Shares thereby purchased at the election of the Warrantholder by (i) tendering in cash, by certified or cashier’s check payable to the order of the Corporation, or by wire transfer of immediately available funds to an account designated by the Corporation, (ii) electing a cashless exercise pursuant to Section 3(b), or (iii) offsetting the Exercise Price against the Warrantholder’s Series A Liquidation Preference as set forth in Section 3(c).

(b) If, as of the day immediately preceding the time a Notice of Exercise is delivered to the Corporation, the Market Price of one Share is greater than the Exercise Price, in lieu of exercising this Warrant for cash, the Warrantholder may elect to receive Shares equal to the value (as determined below) of this Warrant (or the portion thereof being exercised) by surrender of this Warrant and Notice of Exercise (which shall include notice of such election) in which event the Corporation shall issue to the Warrantholder a number of Shares computed using the following formula:


X = Y (A-B)
A
Where:
X = the number of Shares to be issued to the Warrantholder
Y = the number of Shares purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised
A = the Market Price of one Share set forth above
B = the Exercise Price

(c) In lieu of exercising this Warrant for cash, the Warrantholder may elect to pay the aggregate Exercise Price payable for the Shares being purchased by delivering to the Corporation for cancellation such number of shares of Series A held by the Warrantholder having an aggregate Liquidation Preference equal to such aggregate Exercise Price as of the date of such payment.

(d) If the Warrantholder does not exercise this Warrant in its entirety, the Warrantholder will be entitled to receive from the Corporation within a reasonable time, and in any event not exceeding five business days, a new warrant in substantially identical form for the purchase of that number of Shares equal to the difference between the number of Shares subject to this Warrant and the number of Shares as to which this Warrant is so exercised. Notwithstanding anything in this Warrant to the contrary, the Warrantholder hereby acknowledges and agrees that its exercise of this Warrant for Shares is subject to the condition that the Warrantholder will have first received any applicable Regulatory Approvals.

4. Forced Exercise.

(a) After the Effective Date, if the Conditions to Forced Exercise have been satisfied, the Corporation may force exercise of this Warrant by the Warrantholder, in whole or in part, as set forth in this Section 4, by delivering to the Warrantholder a notice thereof in the form annexed hereto (“Forced Exercise Notice”), duly completed and executed on behalf of the Corporation. The aggregate number of Shares to be exercised with respect to all warrants issued pursuant to

the Purchase Agreement and the 2010 Purchase Agreement, including this Warrant (the “Forced Shares”), shall not be less than 750,000 or greater than 50% of the trading volume of the Common Stock during the twenty (20) trading days preceding the date of the Forced Exercise Notice. Within forty (40) business days after receipt of the Forced Exercise Notice, the Warrantholder shall deliver to the Corporation a Notice of Exercise as set forth in Section 3(a) for the Forced Shares applicable to this Warrant. If at any time prior to the delivery of the Notice of Exercise by the Warantholder, the Conditions to Forced Exercise cease to be met, the Forced Exercise Notice shall be deemed to have been revoked.

(b) In no event shall the Warrantholder be forced to exercise in excess of 50% of all Shares issuable hereunder nor shall the Corporation be permitted to deliver more than one Forced Exercise Notice in any three (3) month period. If the Corporation forces an exercise pursuant to this Section 4, it must then simultaneously take the same action in the same proportion with respect to any other warrants issued pursuant to the Purchase Agreement.

“Conditions to Forced Exercise” means that each of the following conditions have been met: (i) the Weighted Average Price of the Common Stock exceeds 300% of the Exercise Price (subject to appropriate adjustments for stock splits, stock dividends, stock combinations and other similar transactions after the Issue Date) for the thirty (30) consecutive trading days immediately preceding the date of delivery of the Forced Exercise Notice; (ii) a registration statement is effective and available for the resale of all remaining Common Stock issuable upon exercise of the Warrants; (iii) the Common Stock is designated for quotation on the NASDAQ Global Market or another U.S. national securities exchange and must not have been suspended from trading on such market nor shall delisting or suspension by such market been threatened or pending either (A) in writing by such market, or (B) by falling below the minimum listing maintenance requirements of such market; and (iv) the Corporation otherwise must be in material compliance with and must not have breached in any material respect any provision, covenant, representation or warranty of any Transaction Document that remains uncured.

“Weighted Average Price” means, with respect to the Common Stock as of any date, the dollar volume-weighted average price for such security on the NASDAQ Global Market or, if the Common Stock is no longer traded on the NASDAQ Global Market, the principal U.S. national securities exchange on which the Common Stock is then traded, during the period beginning at 9:30:01 a.m., New York Time (or such other time as the NASDAQ Global Market or such exchange publicly announces is the official open of trading), and ending at 4:00:00 p.m., New York Time (or such other time as the NASDAQ Global Market or such exchange publicly announces is the official close of trading) as reported by Bloomberg through its “Volume at Price” functions.

5. Issuance of Shares; Authorization; Listing. Subject to compliance with the transfer restrictions applicable to this Warrant and the Shares pursuant to the provisions hereof and the Purchase Agreement, certificates for Shares issued upon exercise of this Warrant shall be issued in such name or names as the Warrantholder may designate and shall be delivered to such named Person or Persons within a reasonable time, not to exceed three business days after the date on which this Warrant has been duly exercised and the Exercise Price for the Shares thereby

purchased has been duly delivered, in accordance with the terms of this Warrant. The Corporation hereby represents and warrants that any Shares issued upon the exercise of this Warrant in accordance with the provisions of Section 3 will be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges (other than liens or charges created by the Warrantholder, except as otherwise provided herein, income and franchise taxes incurred in connection with the exercise of the Warrant or taxes in respect of any transfer occurring contemporaneously therewith). The Shares so issued shall be deemed to have been issued to the Warrantholder as of the close of business on the date on which this Warrant and payment of the Exercise Price are delivered to the Corporation in accordance with the terms of this Warrant, notwithstanding that the stock transfer books of the Corporation may then be closed or certificates representing such Shares may not be actually delivered on such date. The Corporation shall at all times reserve and keep available, out of its authorized but unissued Common Stock, solely for the purpose of providing for the exercise of this Warrant, the aggregate number of shares of Common Stock issuable upon exercise of this Warrant. The Corporation shall (A) procure, at its sole expense, the listing of the Shares issuable upon exercise of this Warrant, subject to issuance or notice of issuance, on all principal stock exchanges on which the Common Stock is then listed or traded and (B) maintain such listings of such Shares at all times after issuance. The Corporation shall use reasonable best efforts to ensure that the Shares may be issued without violation of any applicable law or regulation or of any requirement of any securities exchange on which the Shares are listed or traded. The Corporation and the Warrantholder shall reasonably cooperate to take such other actions as are necessary to obtain (i) any Regulatory Approvals applicable to Warrantholder’s exercise of its rights hereunder, including with respect to the issuance of the Shares and (ii) any regulatory approvals applicable to the Corporation as a result of the issuance of the Shares.

6. No Fractional Shares or Scrip. No fractional Shares or scrip representing fractional Shares shall be issued upon any exercise of this Warrant. In lieu of any fractional Share to which the Warrantholder would otherwise be entitled, the Warrantholder shall be entitled to receive a cash payment equal to the Market Price of the Common Stock on the last trading day preceding the date of exercise less the Exercise Price for such fractional share; provided, however, that the Corporation may, at its option, round up to the nearest whole share of Common Stock in lieu of any cash payment.

7. No Rights as Stockholders; Transfer Books. This Warrant does not entitle the Warrantholder to any voting rights or other rights as a stockholder of the Corporation prior to the date of exercise hereof. The Corporation shall at no time close its transfer books against transfer of this Warrant in any manner which interferes with the timely exercise of this Warrant.

8. Charges, Taxes and Expenses. Issuance of certificates for Shares to the Warrantholder upon the exercise of this Warrant shall be made without charge to the Warrantholder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Corporation.

9. Transfer/Assignment.

(a) Subject to compliance with clauses (b) and (c) of this Section 9, this Warrant and all rights hereunder are transferable, in whole or in part, upon the books of the Corporation by the registered holder hereof in person or by duly authorized attorney, and a new warrant shall be made and delivered by the Corporation, of the same tenor and date as this Warrant but registered in the name of one or more transferees, upon surrender of this Warrant, duly endorsed, to the office or agency of the Corporation described in Section 3. All expenses (other than stock transfer taxes) and other charges payable in connection with the preparation, execution and delivery of the new warrants pursuant to this Section 9 shall be paid by the Corporation.

(b) Notwithstanding the foregoing, this Warrant and any rights hereunder, and any Shares issued upon exercise of this Warrant, shall be subject to the applicable restrictions as set forth in Section 4.3 of the Purchase Agreement.

(c) If and for so long as required by the Purchase Agreement, this Warrant Certificate shall contain a legend as set forth in Section 4.4 of the Purchase Agreement.

10. Exchange and Registry of Warrant. This Warrant is exchangeable, upon the surrender hereof by the Warrantholder to the Corporation, for a new warrant or warrants of like tenor and representing the right to purchase the same aggregate number of Shares. The Corporation shall maintain a registry showing the name and address of the Warrantholder as the registered holder of this Warrant. This Warrant may be surrendered for exchange or exercise, in accordance with its terms, at the office of the Corporation, and the Corporation shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry.

11. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Corporation of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in the case of any such loss, theft or destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the Corporation, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Corporation shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and representing the right to purchase the same aggregate number of Shares as provided for in such lost, stolen, destroyed or mutilated Warrant.

12. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a business day, then such action may be taken or such right may be exercised on the next succeeding day that is a business day.

13. Rule 144 Information. The Corporation shall use its reasonable best efforts to timely file all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations promulgated by the SEC thereunder (or, if the Corporation is not required to file such reports, it shall, upon the request of any Warrantholder, make publicly available such information as necessary to permit sales pursuant to Rule 144 or Regulation S under the Securities Act), and it shall use reasonable best efforts to take such further action as any Warrantholder may reasonably request, in each case to the extent required from time to time to enable such holder to, if permitted by the terms of this Warrant and the Purchase Agreement, sell this Warrant without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144 or Regulation S under the Securities Act,

as such rules may be amended from time to time, or (B) any successor rule or regulation hereafter adopted by the SEC. Upon the written request of any Warrantholder, the Corporation will deliver to such Warrantholder a written statement that it has complied with such requirements.

14. Adjustments and Other Rights. The Exercise Price and the number of Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as follows:

(a) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Corporation shall (i) declare and pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares, or (iii) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of Shares issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be proportionately adjusted so that the Warrantholder after such date shall be entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to this Warrant after such date had this Warrant been exercised immediately prior to such date. In such event, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be adjusted to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution, subdivision, combination or reclassification giving rise to this adjustment by (y) the new number of Shares issuable upon exercise of the Warrant determined pursuant to the immediately preceding sentence.

(b) Reorganization, Consolidation, Merger and Other Changes. In case of any capital reorganization or change in the Common Stock of the Corporation (other than as a result of a subdivision, combination, or stock dividend provided for in Section 14(a) above), or consolidation or merger of the Corporation with or into another entity, or the sale of all or substantially all of its assets to another entity shall be effected in such a way that holders of the Corporation’s Common Stock shall be entitled to receive stock, securities or assets with respect to or in exchange for such Common Stock, then, as a condition of such reorganization, change, consolidation, merger or sale, lawful provision shall be made, and duly executed documents evidencing the same from the Corporation or its successor shall be delivered to the Warrantholder, so that the Warrantholder shall have the right at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and other securities and property receivable in connection with such reclassification, reorganization, change, consolidation, merger or sale by a holder of the same number of shares of Common Stock as were purchasable by the Warrantholder immediately prior to such reclassification, reorganization, change, consolidation, merger or sale. In any such case appropriate provisions shall be made with respect to the rights and interest of the Warrantholder so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities and property deliverable upon exercise hereof, and appropriate adjustments shall be made to the purchase price per share payable hereunder, provided the aggregate purchase price shall remain the same.

(c) Whenever the Exercise Price or the number of Shares into which this Warrant is exercisable shall be adjusted as provided in this Section 14, the Corporation shall forthwith file at the principal office of the Corporation a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and the number of Shares into which this Warrant shall be exercisable after such adjustment, and the Corporation shall also cause a copy of such statement to be sent to each Warrantholder at the address appearing in the Corporation’s records.

15. Governing Law. This Warrant will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within such State. Each of the parties hereto agrees (a) to submit to the non-exclusive personal jurisdiction of the State or Federal courts in the Borough of Manhattan, The City of New York, (b) that non-exclusive jurisdiction and venue shall lie in the State or Federal courts in the State of New York, and (c) that notice may be served upon such party at the address and in the manner set forth for such party in Section 3 hereof. To the extent permitted by applicable law, each of the parties hereto hereby unconditionally waives trial by jury in any legal action or proceeding relating to the Transaction Documents or the transactions contemplated hereby or thereby.

16. Binding Effect. This Warrant shall be binding upon any successors or assigns of the Corporation.

17. Amendments. This Warrant may be amended and the observance of any term of this Warrant may be waived only with the written consent of the Corporation and the Warrantholder.

18. Notices. Any notice, request, instruction or other document to be given hereunder by any party to the other will be in writing and will be deemed to have been duly given (a) on the date of delivery if delivered personally, or by facsimile, upon confirmation of receipt, or (b) on the second business day following the date of dispatch if delivered by a recognized next day courier service.
