As of their respective dates, the SEC Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act, as applicable, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Company is not and has never been an issuer subject to Rule 144(i) under the Securities Act. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments. The agreements and documents described in the Registration Statement, the Preliminary Prospectus, the General Disclosure Package, the Prospectus, and the SEC Reports conform in all material aspects to the descriptions thereof contained therein and there are no agreements or other documents required by the Securities Act and the rules and regulations thereunder to be described in the Registration Statement, the Preliminary Prospectus, the General Disclosure Package, the Prospectus or the SEC Reports or to be filed with the Commission as exhibits to the Registration Statement, that have not been so described or filed. Each agreement or other instrument (however characterized or described) to which the Company is a party or by which it is or may be bound or affected and (i) that is referred to in the Registration Statement, the General Disclosure Package, the Prospectus or the SEC Reports, or (ii) is material to the Company’s business, has been duly authorized and validly executed by the Company, is in full force and effect in all material respects and is enforceable against the Company and, to the Company’s knowledge, the other parties thereto, in accordance with its terms, except (x) as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, (y) as enforceability of any indemnification or contribution provision may be limited under the federal and state securities laws, and (z) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefore may be brought. None of such agreements or instruments has been assigned by the Company, and neither the Company nor, to the best of the Company’s knowledge, any other party is in default thereunder and, to the best of the Company’s knowledge, no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default thereunder. To the best of the Company’s knowledge, performance by the Company of the material provisions of such agreements or instruments will not result in a violation of any existing applicable law, rule, regulation, judgment, order or decree of any governmental agency or court, domestic or foreign, having jurisdiction over the Company or any of its assets or businesses, including, without limitation, those relating to environmental laws and regulations.

(j) Material Changes; Undisclosed Events, Liabilities or Developments. Since the date of the latest audited financial statements included within the SEC Reports, except as specifically disclosed in a subsequent SEC Report filed prior to the date hereof or except with respect to the Offering, (i) there has been no event, occurrence or development that has had or that could reasonably be expected to result in a Material Adverse Effect, (ii) the Company has not incurred any liabilities (contingent or otherwise) other than (A) trade payables and accrued expenses incurred in the ordinary course of business consistent with past practice and (B) liabilities not required to be reflected in the Company’s financial statements pursuant to GAAP or disclosed in filings made with the Commission, (iii) the Company has not altered its method of accounting in any material respect, (iv) the Company has not declared or made any dividend or distribution of cash or other property to its stockholders or purchased, redeemed or made any agreements to purchase or redeem any shares of its capital stock and (v) the Company has not issued any equity securities to any officer, director or Affiliate, except pursuant to existing Company stock option plans and employee

10

stock purchase plans, and except for the issuance of Common Stock Equivalents as disclosed in the SEC Reports. The Company does not have pending before the Commission any request for confidential treatment of information. Except for the issuance of the Securities contemplated by this Agreement, no event, liability, fact, circumstance, occurrence or development has occurred or exists with respect to the Company or its Subsidiaries or their respective businesses, prospects, properties, operations, assets or financial condition that would be required to be disclosed by the Company under applicable securities laws at the time this representation is made or deemed made that has not been publicly disclosed at least one Trading Day prior to the date that this representation is made. Unless otherwise disclosed in an SEC Report filed prior to the date hereof, the Company has not: (i) issued any securities or incurred any liability or obligation, direct or contingent, for borrowed money; or (ii) declared or paid any dividend or made any other distribution on or in respect to its capital stock. There are no statutes, regulations, contracts or documents that are required to be described in the Registration Statement, in the General Disclosure Package and in the Prospectus or required to be filed as exhibits to the Registration Statement by the Securities Act or by the rules and regulations thereunder that have not been so described or filed.

(k) Litigation. There are no actions, suits, inquiries, notices of violation, proceedings or investigations pending or, to the knowledge of the Company, threatened against or affecting the Company, any Subsidiary or any of their respective properties before or by any court, arbitrator, governmental or administrative agency or regulatory authority (federal, state, county, local or foreign) (collectively, an “Action”) which (i) adversely affects or challenges the legality, validity or enforceability of any of the Transaction Documents or the Securities or (ii) could, if there were an unfavorable decision, have or reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any Subsidiary, nor, to the Company’s knowledge, any director or officer thereof, is or has been the subject of any Action involving a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty. To the knowledge of the Company, there has not been, and there is not pending or threatened, any investigation by the Commission involving the Company or any current or former director or officer of the Company. There are no Actions required to be disclosed in the SEC Reports that have not been disclosed. The Commission has not issued any stop order or other order suspending the effectiveness of any registration statement filed by the Company or any Subsidiary under the Exchange Act or the Securities Act.

(l) Labor Matters. No labor problem or dispute with the employees of the Company or any of its Subsidiaries exists or is threatened or imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or its subsidiaries’ principal suppliers, contractors or customers, that could have a Material Adverse Effect.

(m) Compliance. Neither the Company nor any Subsidiary: (i) is in default under or in violation of (and no event has occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the Company or any Subsidiary under), nor has the Company or any Subsidiary received notice of a claim that it is in default under or that it is in violation of, any indenture, loan or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its properties is bound (whether or not such default or violation has been waived), (ii) is in violation of any judgment, decree or order of any court, arbitrator or other governmental authority or (iii) is or has been in violation of any statute, rule, ordinance or regulation of any governmental authority, including without limitation all foreign, federal, state and local laws relating to taxes, environmental protection, occupational health and safety, product quality and safety and employment and labor matters, except in each case as would not have or reasonably be expected to result in a Material Adverse Effect.

(n) Environmental Laws. The Company and its Subsidiaries (i) are in compliance with all federal, state, local and foreign laws relating to pollution or protection of human health or the environment (including ambient air, surface water, groundwater, land surface or subsurface strata), including laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees, demands, or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations, issued, entered, promulgated or approved thereunder (“Environmental Laws”); (ii) have received all permits licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses; and (iii) are in compliance with all terms and conditions of any such permit, license or approval where in each clause (i), (ii) and (iii), the failure to so comply would be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect.

11

(o) Regulatory Permits. The Company and the Subsidiaries possess all licenses, certificates, authorizations, approvals, clearances, consents, registrations, and permits issued by the appropriate federal, state, local or foreign regulatory authorities applicable to the Company (“Applicable Laws”) necessary to conduct their respective businesses as described in the SEC Reports, except where the failure to possess such permits would not reasonably be expected to result in a Material Adverse Effect (each, an “Authorization”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of any Authorization or the noncompliance with any ordinance, law, rule or regulation applicable to the Company. The disclosures in the Registration Statement concerning the effects of federal, state, local and all foreign regulation on the Company’s business as currently contemplated are correct in all material respects. The Company is and has been in material compliance with any term of any such Authorizations, except for any violations which would not reasonably be expected to have a Material Adverse Effect. The Company has not received notice of any claim, action, suit, proceeding, hearing, enforcement, investigation, arbitration or other action from any governmental authority or body or third party alleging that any product, operation or activity is in violation of any Applicable Laws or Authorizations or has any knowledge that any such entity or third party is considering any such claim, litigation, arbitration, action, suit, investigation or proceeding, nor, to the Company’s knowledge, has there been any material noncompliance with or violation of any Applicable Laws by the Company that could reasonably be expected to require the issuance of any such communication or result in an investigation, corrective action, or enforcement action by any governmental body or entity.

(p) Title to Assets. The Company and the Subsidiaries have good and marketable title in fee simple to all real property owned by them and good and marketable title in all personal property owned by them that is material to the business of the Company and the Subsidiaries, in each case free and clear of all Liens, except for (i) Liens as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries and (ii) Liens for the payment of federal, state or other taxes, for which appropriate reserves have been made therefor in accordance with GAAP and, the payment of which is neither delinquent nor subject to penalties.

(q) Intellectual Property.

(i) To the knowledge of the Company, the Company and each of its Subsidiaries owns or has the right to use pursuant to a valid, binding and enforceable written license or other legally enforceable right, all Intellectual Property (as defined below) necessary for the conduct of the Company’s and its Subsidiaries’ businesses as now conducted and as described in the Registration Statement, the General Disclosure Package and the Prospectus to be conducted (the “Company IP”), except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. “Intellectual Property” means all patents, patent applications, trade and service marks, trade and service mark registrations, trade names, copyrights, licenses, inventions, trade secrets, domain names, technology, know-how and other intellectual property of the Company and its subsidiaries.

(ii) To the knowledge of the Company, there is no infringement, misappropriation or violation by third parties of any Company IP. There is no pending or, to the knowledge of the Company, threatened, action, suit, proceeding or claim by others challenging the Company’s or its Subsidiaries’ rights in or to any Company IP, except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Intellectual Property owned by the Company and its Subsidiaries, and to the knowledge of the Company, the Intellectual Property licensed to the Company and its Subsidiaries, has not been adjudged invalid or unenforceable, in whole or in part, and there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding or claim by others challenging the validity or scope of any Company IP, and the Company is unaware of any facts which would form a reasonable basis for any such claim.

(iii) To the Company’s knowledge, no employee of the Company or any of its Subsidiaries is in or has ever been in material violation of any term of any employment contract, patent disclosure agreement, invention assignment agreement, non-competition agreement, non-solicitation agreement, nondisclosure agreement or any restrictive covenant to or with a former employer where the basis of such violation relates to such employee’s employment with the Company or any of its subsidiaries or actions undertaken by the employee while employed with the Company or any of its Subsidiaries.

12

(iv) The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of the Company IP, except where failure to do so would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(v) All patent applications owned by the Company or its Subsidiaries and filed with the U.S. Patent and Trademark Office (the “PTO”) or any foreign or international patent authority that have resulted in patents or currently pending applications that describe inventions necessary to conduct the business of the Company or its Subsidiaries as now conducted or as described in the Registration Statement, the General Disclosure Package and the Prospectus to be conducted (collectively, the “Company Patent Applications”) have been or were duly and properly filed.

(vi) The Company and its Subsidiaries have complied with their duty of candor and disclosure to the PTO for the Company Patent Applications. To the Company’s knowledge, there are no facts required to be disclosed to the PTO that were not disclosed to the PTO and which would preclude the grant of a patent for the Company Patent Applications. The Company has no knowledge of any facts which would preclude it or its applicable subsidiary from having clear title to the Company Patent Applications that have been identified by the Company as being exclusively owned by the Company or one of its Subsidiaries.

(r) Insurance. The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged, including, but not limited to, directors and officers insurance coverage. Neither the Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without a significant increase in cost.

(s) Transactions With Affiliates and Employees. None of the officers or directors of the Company or any Subsidiary and, to the knowledge of the Company, none of the employees of the Company or any Subsidiary is presently a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, providing for the borrowing of money from or lending of money to or otherwise requiring payments to or from, any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee, stockholder, member or partner, in each case in excess of $120,000 other than for (i) payment of salary or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf of the Company and (iii) other employee benefits, including stock option agreements under any stock option plan of the Company.

(t) Sarbanes-Oxley; Internal Accounting Controls; Disclosure Controls. The Company and its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company’s internal control over financial reporting is effective and none of the Company, its board of directors and audit committee is aware of any “significant deficiencies” or “material weaknesses” (each as defined by the Public Company Accounting Oversight Board) in its internal control over financial reporting, or any fraud, whether or not material, that involves management or other employees of the Company and its subsidiaries who have a significant role in the Company’s internal controls; and since the end of the latest audited fiscal year, there has been no change in the Company’s internal control over financial reporting (whether or not remediated) that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Board of Directors has, subject to the exceptions, cure periods and the phase in periods specified in the applicable stock exchange rules (“Exchange Rules”), validly appointed an audit committee to oversee internal accounting controls whose composition satisfies the applicable requirements of the Exchange Rules and the Board of Directors and/or the audit committee has adopted a charter that satisfies the requirements of the Exchange Rules. The Company is in compliance with all applicable provisions of the Sarbanes-Oxley Act and the rules and regulations of the Commission thereunder. The Company has established and maintains disclosure controls and procedures (as defined in Rules 13a-14 and 15d-14 under the Exchange Act) and such controls and procedures

13

are effective in ensuring that material information relating to the Company, including its subsidiaries, is made known to the principal executive officer and the principal financial officer. The Company has utilized such controls and procedures in preparing and evaluating the disclosures in the Registration Statement, in the General Disclosure Package and in the Prospectus.

(u) Certain Fees. Except as set forth in the Registration Statement, the General Disclosure Package and the Prospectus, no brokerage or finder’s fees or commissions are or will be payable by the Company, any Subsidiary or Affiliate of the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents. There are no other arrangements, agreements or understandings of the Company or, to the Company’s knowledge, any of its stockholders that may affect the Underwriters’ compensation, as determined by FINRA. Other than payments to the Underwriters for this Offering’, the Company has not made and has no agreements, arrangements or understanding to make any direct or indirect payments (in cash, securities or otherwise) to: (i) any person, as a finder’s fee, consulting fee or otherwise, in consideration of such person raising capital for the Company or introducing to the Company persons who raised or provided capital to the Company; (ii) any FINRA member; or (iii) any person or entity that has any direct or indirect affiliation or association with any FINRA member, within the 180-day period preceding the initial filing of the Registration Statement through the 60-day period after the Effective Date. None of the net proceeds of the Offering will be paid by the Company to any participating FINRA member or its affiliates, except as specifically authorized herein.

(v) Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the Firm Securities will not be or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The Company shall conduct its business in a manner so that it will not become an “investment company” subject to registration under the Investment Company Act of 1940, as amended.

(w) Registration Rights. No Person has any right to cause the Company or any Subsidiary to effect the registration under the Securities Act of any securities of the Company or any Subsidiary, other than those rights that have been disclosed in the Registration Statement or have been waived or satisfied.

(x) Listing and Maintenance Requirements. The Series J Preferred Stock is currently eligible for electronic transfer through the Depository Trust Company or another established clearing corporation and the Company is current in payment of the fees of the Depository Trust Company (or such other established clearing corporation) in connection with such electronic transfer. Except as previously disclosed to counsel for the Underwriters or as set forth in the Registration Statement, the General Disclosure Package and the Prospectus, to the knowledge of the Company, no beneficial owners of the Company’s capital stock who, together with their associated persons and affiliates, hold in the aggregate 10% or more of such capital stock, have any direct or indirect association or affiliate with a FINRA member.

(y) Application of Takeover Protections. The Company and the Board of Directors have taken or prior to the Closing Date will have taken all necessary action within its power, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s articles of incorporation (or similar charter documents) or the laws of its state of incorporation that is or would become applicable as a result of the Underwriters and the Company fulfilling their obligations or exercising their rights under the Transaction Documents.

(z) Disclosure; 10b-5. The Registration Statement (and any further documents to be filed with the Commission) contains all exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, if any, at the time it became effective, complied in all material respects with the Securities Act and the Exchange Act and the applicable rules and regulations under the Securities Act and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Preliminary Prospectus and the Prospectus, each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable rules and regulations. The Prospectus, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except for any statements in or omissions from the Prospectus based upon and in

14

conformity with written information furnished to the Company by any Underwriter, it being understood that such information furnished by any Underwriter shall consist of the Underwriters’ Information (as defined below). As of its date and the date hereof, the General Disclosure Package did not and does not include any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except for any statements in or omissions from the General Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter, it being understood that such information furnished by any Underwriter shall consist of the Underwriters’ Information. The SEC Reports, when they were filed with the Commission, conformed in all material respects to the requirements of the Securities Act and the Exchange Act, as applicable, and the applicable rules and regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein (with respect to the SEC Reports incorporated by reference in the Prospectus), in light of the circumstances under which they were made not misleading; and any further documents so filed and incorporated by reference in the Prospectus, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the applicable rules and regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made not misleading. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually or in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission. There are no documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have not been filed as required pursuant to the Securities Act or (y) will not be filed within the requisite time period. There are no contracts or other documents required to be described in the Preliminary Prospectus or Prospectus, or to be filed as exhibits or schedules to the Registration Statement, which have not been described or filed as required. The press releases disseminated by the Company during the twelve months preceding the date of this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made and when made, not misleading.

(aa) 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 security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of any applicable shareholder approval provisions of any Trading Market on which any of the securities of the Company are listed or designated.

(bb) Solvency. Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the Company of the proceeds from the sale of the Firm Securities hereunder, (i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date. The SEC Reports sets forth as of the date hereof all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which the Company or any Subsidiary has commitments. Neither the Company nor any Subsidiary is in default with respect to any Indebtedness.

(cc) Tax Status. Except as would not reasonably be expected to result, individually or in the aggregate, in a Material Adverse Effect, each of the Company and its Subsidiaries (i) has made or filed all United States federal, state and local income and all foreign income and franchise tax returns, reports and declarations required by any jurisdiction to which it is subject, (ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on such returns, reports and declarations and (iii) has set aside on its books provision reasonably adequate for the payment of all material taxes for periods subsequent to the periods to

15

which such returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company or of any Subsidiary know of no basis for any such claim. The provisions for taxes payable, if any, shown on the financial statements filed with or as part of the Registration Statement are sufficient for all accrued and unpaid taxes, whether or not disputed, and for all periods to and including the dates of such consolidated financial statements. The term “taxes” mean all federal, state, local, foreign, and other net income, gross income, gross receipts, sales, use, ad valorem, transfer, franchise, profits, license, lease, service, service use, withholding, payroll, employment, excise, severance, stamp, occupation, premium, property, windfall profits, customs, duties or other taxes, fees, assessments, or charges of any kind whatsoever, together with any interest and any penalties, additions to tax, or additional amounts with respect thereto. The term “returns” means all returns, declarations, reports, statements, and other documents required to be filed in respect to taxes.

To the knowledge of the Company, Macias Gini & O’Connell LLP, the current independent registered public accounting firm of the Company, is an independent registered public accounting firm as required by the Securities Act and the Exchange Act.

The description of the Company’s stock option, stock bonus and other stock incentive plans or similar incentive plans and compensation arrangements (the “Company Stock Plans”), and the options or other rights granted thereunder (collectively, the “Awards”), set forth in the Registration Statement, the General Disclosure Package and the Prospectus presents accurately and fairly in all material respects the information required to be shown with respect to such plans, arrangements and Awards. Each grant of an Award (A) was duly authorized no later than the date on which the grant of such Award was by its terms to be effective by all necessary corporate action, including, as applicable, approval by the board of directors of the Company (or a duly constituted and authorized committee thereof) and any required stockholder approval by the necessary number of votes or written consents, and the award agreement governing such grant (if any) was duly executed and delivered by each party thereto and (B) was made in accordance with the terms of the applicable Company Stock Plan, and all applicable laws and regulatory rules or requirements, including all applicable federal securities laws. No Award under any of the Company Stock Plans has been backdated. The Company has not knowingly granted, and there is no and has been no Company policy or practice to knowingly grant, stock options prior to, or otherwise knowingly coordinate the grant of stock options with, the release or other public announcement of material information regarding the Company or its Subsidiaries or their financial results or prospects.

(c) Free Writing Prospectuses. The Company represents and agrees that it has not made and will not make any offer relating to the Firm Securities that would constitute an issuer free writing prospectus, as defined in Rule 433 of the rules and regulations under the Securities Act, without the prior written consent of the Representatives. Any such free writing prospectus consented to by the Representatives is herein referred to as a “Permitted Free Writing Prospectus.” The Company represents that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus” as defined in rule and regulations under the Securities Act, and has complied and will comply with the applicable requirements of Rule 433 of the Securities Act, including timely Commission filing where required, legending and record keeping.

If the Commission or any state securities commission shall enter a stop order or suspend such qualification at any time, the Company will make every reasonable effort to obtain promptly the lifting of such order.

If on the Closing Date, any Underwriter shall fail to purchase and pay for the portion of the Firm Securities, which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company), the Representatives, or if a Representative is the defaulting Underwriter, the non-defaulting Underwriters, shall use their reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company such amounts as may be agreed upon and upon the terms set forth herein, the Firm Securities, which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours the Representatives shall not have procured such other Underwriters, or any others, to purchase the Firm Securities, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of Firm Securities with respect to which such default shall occur does not exceed 10% of the Firm Securities covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Firm Securities, which they are obligated to purchase hereunder, to purchase the Firm Securities, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of Firm Securities with respect to which such default shall occur exceeds 10% of the Firm Securities covered hereby, the Company or the Representatives will have the right to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided in Article VI hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Article V, the Closing Date may be postponed for such period, not exceeding seven days, as the Representatives, or if a Representative is the defaulting Underwriter, the non-defaulting Underwriters, may determine in order that the required changes in the Prospectus or in any other documents or arrangements may be effected.

including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Securities Act and the rules and regulations thereunder, as applicable, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, any preliminary prospectus supplement, any Permitted Free Writing Prospectus or the Prospectus (or any amendment or supplement to any of the foregoing) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) any untrue statement or alleged untrue statement of a material fact contained in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities, including any roadshow or investor presentations made to investors by the Company (whether in person or electronically) (collectively, Marketing Materials”) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company shall not be liable to the extent that such loss, claim, liability, expense or damage is based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with Underwriters’ Information. This indemnity agreement will be in addition to any liability that the Company might otherwise have. For all purposes of this Agreement, the information set forth in the Prospectus in the “Price Stabilization, Short Positions and Penalty Bids” and “Electronic Distribution” sections under the caption “Underwriting” constitutes the only information (the “Underwriters’ Information”) relating to the Underwriters furnished in writing to the Company by the Underwriters through the Representatives specifically for inclusion in the preliminary prospectus, the Registration Statement or the Prospectus. With respect to any untrue statement or omission or alleged untrue statement or omission made in the General Disclosure Package, the indemnity agreements contained in this Section 6.1 shall not inure to the benefit of any Underwriter Indemnified Party to the extent that any loss, liability, claim, damage or expense of such Underwriter Indemnified Party results from the fact that a copy of the Prospectus was not given or sent to the person asserting any such loss, liability, claim, damage at or prior to written confirmation of sale of the Firm Securities to such person as required by the Securities Act, and if the untrue statement or omission had been corrected in the Prospectus, unless the failure to deliver the Prospectus was a result of non-compliance by the Company with its obligations under Section 4.3 hereof.

6.2 Indemnification of the Company. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its affiliates, the directors, officers, employees and agents of the Company and each other person or entity, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever, as incurred (including but not limited to reasonable attorneys’ fees and any and all reasonable expenses whatsoever, incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Securities Act and the rules and regulations thereunder , any Preliminary Prospectus, the Prospectus, or any amendment or supplement to any of them, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense (or action in respect thereof) arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon the Underwriters’ Information; provided, however, that in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discount and commissions applicable to the Firm Securities purchased by such Underwriter hereunder.

6.3 Indemnification Procedures. Any party that proposes to assert the right to be indemnified under this Section 6 shall, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 6, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this Section 6 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled

25

to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable out-of-pocket costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) the indemnified party has reasonably concluded that a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party), (iv) the indemnifying party does not diligently defend the action after assumption of the defense, or (v) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel shall be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges shall be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party shall not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld or delayed). No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 6 (whether or not any indemnified party is a party thereto), unless (x) such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, and (y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment. Notwithstanding the foregoing, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a) effected without its written consent if (A) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (B) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

6.4 Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 6 is applicable in accordance with its terms but for any reason is held to be unavailable, the Company and the Underwriters shall contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Underwriters, such as persons who control the Company within the meaning of the Securities Act, officers of the Company who signed the Registration Statement and directors of the Company, who may also be liable for contribution), to which the Company and the Underwriter may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities pursuant to this Agreement. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as (x) the total proceeds from the Offering (net of underwriting discount and commissions but before deducting expenses) received by the Company bears to (y) the underwriting discount and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, with respect to the statements

26

or omissions which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 6.4 were to be determined by pro rata allocation or by any other method of allocation (even if the Underwriters were treated as one entity for such purpose) which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 6.4 shall be deemed to include, for purpose of this Section 6.4, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6.4, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by it. No person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6.4, any person who controls a party to this Agreement within the meaning of the Securities Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, and each director, officer, employee, counsel or agent of an Underwriter will have the same rights to contribution as such Underwriter, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 6.4, will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 6.4. The obligations of the Underwriters to contribute pursuant to this Section 6.4 are several in proportion to the respective number of Securities to be purchased by each of the Underwriters hereunder and not joint. No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld).

6.5 Survival. The indemnity and contribution agreements contained in this Section 6 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or any controlling Person thereof, (ii) acceptance of any of the Securities and payment therefor or (iii) any termination of this Agreement.

ARTICLE VII.

MISCELLANEOUS

7.1 Termination.

(a) Termination Right. The Representatives shall have the right to terminate this Agreement at any time prior to any Closing Date, (i) if any domestic or international event or act or occurrence has materially disrupted, or in their opinion will in the immediate future materially disrupt, general securities markets in the United States; or (ii) if trading on any Trading Market shall have been suspended or materially limited, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required by FINRA or by order of the Commission or any other government authority having jurisdiction, or (iii) if the United States shall have become involved in a new war or an increase in major hostilities, which will, in the Representatives’ opinion, make it inadvisable to proceed with the delivery of the Securities or (iv) if a banking moratorium has been declared by a New York State or federal authority, or (v) if a moratorium on foreign exchange trading has been declared which materially adversely impacts the United States securities markets, or (vi) if the Company shall have sustained a material loss by fire, flood, accident, hurricane, earthquake, theft, sabotage or other calamity or malicious act which, whether or not such loss shall have been insured, will, in the Representatives’ opinion, make it inadvisable to proceed with the delivery of the Securities, or (vii) if the Company is in material breach of any of its representations, warranties or covenants hereunder, or (viii) if the Representatives shall have become aware after the date hereof of such a material adverse change in the conditions or prospects of the Company, or such adverse material change in general market conditions as in the Representatives’ judgment would make it impracticable to proceed with the offering, sale and/or delivery of the Securities or to enforce contracts made by the Underwriters for the sale of the Securities.

27

(b) Expenses. In the event this Agreement shall be terminated pursuant to Section 7.1(a), within the time specified herein or any extensions thereof pursuant to the terms herein, the Company shall be obligated to pay to the Representatives their actual and accountable out-of-pocket expenses related to the transactions contemplated herein then due and payable up to $125,000 (provided, however, that such expense cap in no way limits or impairs the indemnification and contribution provisions of this Agreement).

7.4 Amendments; Waivers. No provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Representatives. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

7.5 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.

7.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns.

7.7 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof.

Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any action, suit or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit,

28

action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company under Article VI, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

7.8 Survival. The representations and warranties contained herein shall survive the Closing Date and the delivery of the Securities.

This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

7.10 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

7.11 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Underwriters and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

7.12 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 Business Day.

Section 6. Conversion.

(a) Conversions at Option of Holder. Subject to Section 6(d), each share of Series J Preferred Stock shall be convertible after its issuance, at any time and from time to time from and after the Original Issue Date, at the option of the Holder thereof, into that number of shares of Common Stock determined by dividing the Stated Value of such share of Series J Preferred Stock by the Conversion Price. Holders shall effect conversions by delivering to the Corporation a conversion notice in the form attached hereto as Annex A (a “Notice of Conversion”). Each Notice of Conversion shall specify the number of shares of Series J Preferred Stock to be converted, the number of shares of Series J Preferred Stock owned prior to the conversion at issue, the number of shares of Series J Preferred Stock owned subsequent to the conversion at issue and the date on which such conversion is to be effected, which date may not be prior to the date the applicable Holder delivers such Notice of Conversion to the Corporation (such date, the “Conversion Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be as of the close of business on the Business Day that such Notice of Conversion is delivered to the Corporation, or if such day is not a Business Day or if the Notice of Conversion is delivered after regular business hours, the next Business Day. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be required. The calculations and entries set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error. From and after the Conversion Date, until presented for transfer or exchange, certificates (if in certificated form) that previously represented shares of Series J Preferred Stock shall represent, in lieu of the number of shares of Series J Preferred Stock previously represented by such certificate (if in certificated form), the number of shares of Series J Preferred Stock, if any, previously represented by such certificate (if in certificated form) that were not converted pursuant to the Notice of Conversion, plus the number of shares of Conversion Shares into which the shares of Series J Preferred Stock previously represented by such certificate (if in certificated form) were converted. To effect conversions of shares of Series J Preferred Stock, a Holder shall not be required to surrender the certificate(s), if any, representing the shares of Series J Preferred Stock to the Corporation unless all of the shares of Series J Preferred Stock represented thereby are so converted, in which case such Holder shall deliver the certificate representing such shares of Series J Preferred Stock promptly following the Conversion Date at issue. Shares of Series J Preferred Stock converted into Common Stock shall be canceled and shall not be reissued. Without limiting the rights and remedies of a holder of Series J Preferred Stock hereunder and without limiting the right of a Holder to deliver a Notice of Conversion to the

5

Corporation, a holder whose interest in the shares of Series J Preferred Stock is a beneficial interest in certificate(s) representing the shares of Series J Preferred Stock held in book-entry form through DTC (or another established clearing corporation performing similar functions), shall effect conversions made pursuant to this Section 6(a) by delivering to DTC (or such other clearing corporation, as applicable) the appropriate instruction form for conversion, complying with the procedures to effect conversions that are required by DTC (or such other clearing corporation, as applicable).

(b) Conversion Price. The conversion price for the Series J Preferred Stock shall equal $3.26 per share, subject to adjustment herein (the “Conversion Price”).

(c) Mechanics of Conversion.

(d) Beneficial Ownership Limitation. Notwithstanding anything to the contrary set forth herein, the Corporation shall not effect any conversion of the Series J Preferred Stock, and a Holder shall not have the right to convert any portion of the Series J Preferred Stock, to the extent that, after giving effect to the conversion set forth on the applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the Series J Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Series J Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Series J Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 6(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section 6(d) applies, the determination of whether the Series J Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Series J Preferred Stock are convertible shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Series J Preferred Stock may be converted (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and how many shares of the Series J Preferred Stock are convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to the Corporation each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this Section 6(d) and the Corporation shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 6(d), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Corporation’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Corporation or (iii) a more recent written notice by the Corporation or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request (which may be via email) of a Holder, the Corporation shall within one (1) Trading Day confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding

9

shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including the Series J Preferred Stock, by such Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any shares of Series J Preferred Stock, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of Series J Preferred Stock held by the applicable Holder. A Holder, upon notice to the Corporation, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 6(d) applicable to its Series J Preferred Stock; provided, that the Beneficial Ownership Limitation shall not in any event exceed 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Series J Preferred Stock held by the Holder and the provisions of this Section 6(d) shall continue to apply. Any such increase will not be effective until the 61st day after such notice is delivered to the Corporation and shall only apply to such Holder and no other Holder. The Beneficial Ownership Limitation shall not be waived by the Corporation or the Holder and upon issuance of the Series J Preferred Stock by the Corporation, and the purchase thereof by the Holder, each of the Corporation and the Purchaser shall be deemed to acknowledge such limitation and to agree not to waive it. The provisions of this Section 6(d) shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 6(d) to correct this Section (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section shall apply to any successor or assign of a Holder.

Section 7. Certain Adjustments.

(a) Stock Dividends and Stock Splits. If the Corporation, at any time while the Series J Preferred Stock is outstanding: (i) pays a stock dividend or otherwise makes a distribution that is payable in shares of Common Stock on shares of Common Stock or any other Common Stock Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Corporation upon conversion of, or payment of a dividend on, the Series J Preferred Stock), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Corporation, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately before such event, and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section 7(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and, in the case of a subdivision, combination or re-classification, shall become effective immediately after the effective date of such subdivision, combination or re-classification. Notwithstanding the foregoing in no event may the Conversion Price be less than the par value per share of Series J Preferred Stock.

(b) Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 7(a) above, if at any time the Corporation grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of Common Stock or any class thereof (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of such Holder’s Series J Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the record date for the grant, issuance or sale of such Purchase Rights, or, if no such record date is established, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that, to the extent that the Holder’s right to participate in any such Purchase Right would result in

10

the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

(c) Distributions. During such time as the Series J Preferred Stock is outstanding, if the Corporation declares or makes any dividend or other distribution of its assets (or rights to acquire its assets) to holders of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of the Series J Preferred Stock (without regard to any limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the record date for such Distribution, or, if no such record date is established, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, that, to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

(d) Fundamental Transaction. If, at any time while the Series J Preferred Stock is outstanding, (i) the Corporation, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Corporation with or into another Person (other than a merger to bring about a reincorporation under applicable state law and Section 368(a)(1)(F) of the Internal Revenue Code of 1986, as amended, (ii) the Corporation (and all of its Subsidiaries, taken as a whole), directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Corporation or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of at least 50% of the outstanding Common Stock, (iv) the Corporation, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Corporation, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares of Common Stock (each a “Fundamental Transaction”), then, upon any subsequent conversion of the Series J Preferred Stock, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 6(d) on the conversion of the Series J Preferred Stock), the number of shares of Common Stock of the successor or acquiring corporation or of the Corporation, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which the Series J Preferred Stock is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 6(d) on the conversion of the Series J Preferred Stock). For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the

11

Corporation shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of the Series J Preferred Stock following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental Transaction shall file a new Certificate of Designation with the same terms and conditions and issue to the Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate Consideration. The Corporation shall cause any successor entity in a Fundamental Transaction in which the Corporation is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Corporation under this Certificate of Designation in accordance with the provisions of this Section 7(d) pursuant to written agreements in customary form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for the Series J Preferred Stock a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Series J Preferred Stock which is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon conversion of the Series J Preferred Stock (without regard to any limitations on the conversion of the Series J Preferred Stock) prior to such Fundamental Transaction, and with a conversion price which applies the conversion price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such conversion price being for the purpose of protecting the economic value of the Series J Preferred Stock immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Certificate of Designation referring to the “Corporation” shall refer instead to the Successor Entity), and may exercise every right and power of the Corporation and shall assume all of the obligations of the Corporation under this Certificate of Designation with the same effect as if such Successor Entity had been named as the Corporation herein.

(g) Calculations. All calculations under this Section 7 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Corporation) issued and outstanding.

(h) Notice of Holders.

12

Section 8. Covenants. As long as any shares of Series J Preferred Stock or Warrants remain outstanding:

(a) the Corporation is obligated to maintain an effective registration statement under the Securities Act covering: (a) the issuance of shares of Common Stock issuable upon conversion of the Series J Preferred Stock and (b) the issuance of additional shares of Series J Preferred Stock pursuant to the Corporation’s obligation to pay Dividends, in each case, unless there is available an exemption from, or a transaction not subject to, the registration requirements of the Securities Act that would allow the issuance of the Series J Preferred Stock and the Conversion Shares without registration.

Section 9. Redemption

(a) Mandatory Redemption. If any shares of Series J Preferred are outstanding at the end of the Term, then the Corporation shall promptly redeem all of such outstanding shares of Series J Preferred Stock on a pro rata basis among all of the Holders of Series J Preferred Stock commencing on the one-year anniversary of the Original Issue Date (“Mandatory Redemption Date”) in cash at a price per share of Series J Preferred Stock equal to the sum of (x) the Stated Value plus (y) all accrued and unpaid Dividends and (z) all other

13

amounts due in respect of the Series J Preferred Stock (the “Corporation’s Mandatory Redemption Price”). On the Mandatory Redemption Date, the Corporation shall pay the Corporation’s Mandatory Redemption Price, subject to any adjustment pursuant to the immediately preceding sentence, to the Holders of Series J Preferred Stock on a pro rata basis. If a Mandatory Redemption Date is not a Business Day, then the Corporation’s Mandatory Redemption Price shall be due and payable on the Business Day immediately following such Mandatory Redemption Date. The Corporation shall pay the Corporation’s Mandatory Redemption Price due under this Section 9(a) to the Holders in cash. Notwithstanding the foregoing, if the shares of Series J Preferred Stock are issued in book-entry form through DTC or any other similar facility, notice of redemption may be given to the holders of Series J Preferred Stock at such time and in any manner permitted by such facility. The Corporation covenants and agrees that it will honor all Notices of Conversion tendered up until the Mandatory Redemption Share Amount is paid in full.

(j) General. Notwithstanding anything to the foregoing contained herein, on the Mandatory Redemption Date, the Corporation shall redeem, on a pro rata basis in accordance with the number of shares of Series J Preferred Stock owned by each Holder, that number of outstanding shares of Series J Preferred Stock which the Corporation is obligated to redeem pursuant to this Section 9. If on the Mandatory Redemption Date, Delaware law governing distributions to stockholders prevents the Corporation from redeeming all shares of Series J Preferred Stock to be redeemed, the Corporation shall ratably redeem the maximum number of shares of Series J Preferred Stock that it may redeem consistent with such law, until all shares which the Corporation is obligated to redeem pursuant to this Section 9 are redeemed. If on the Mandatory Redemption Date, any cash payment to be made pursuant to this Section 9 is not made, due to the aforementioned prohibitions under Delaware law, then the Corporation shall, provided there is no prohibition under Delaware law, redeem the Series J Preferred Stock by paying to the Holder the unpaid cash redemption payment in duly authorized, validly issued, fully paid and non-assessable shares of Common Stock equal in number to the quotient obtained by dividing such unpaid amount by the closing price of the Common Stock on the Trading Market on the Mandatory Redemption Date.

Section 10. Miscellaneous.

(a) Notices. Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice of Conversion, shall be in writing and delivered personally, by facsimile or email attachment, or sent by a nationally recognized overnight courier service, addressed to the Corporation, at 27042 Towne Centre Drive, Suite 270, Lake Forest, California 92610 Attention: John R.

(b) Lost or Mutilated Preferred Stock Certificate. If a Holder’s Series J Preferred Stock certificate (if in certificated form) shall be mutilated, lost, stolen or destroyed, the Corporation shall execute and deliver, in exchange and substitution for and upon cancellation of a mutilated certificate, or in lieu of or in substitution for a lost, stolen or destroyed certificate, a new certificate for the shares of Series J Preferred Stock so mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or destruction of such certificate, and of the ownership hereof reasonably satisfactory to the Corporation (which shall not include the posting of any bond).

(f) Status of Converted or Redeemed Preferred Stock.

(g) Certificates. The Corporation may at its option issue shares of the Series J Preferred Stock without certificates. If DTC or its nominee is the registered owner of the Series J Preferred Stock, the following provisions of this Section 10 shall apply. If and as long as DTC or its nominee is the registered owner of the Series J Preferred Stock, DTC or its nominee, as the case may be, shall be considered the sole owner and holder of all such shares of the Series J Preferred Stock of which DTC or its nominee is the registered owner for all purposes under the instruments governing the rights and obligations of holders of shares of the Series J Preferred Stock.

WHEREAS, pursuant to the terms of that certain underwriting agreement (the “Underwriting Agreement”), dated September 13, 2023, by and between the Company, Lake Street Capital Markets, LLC and Maxim Group LLC, as representatives of the underwriters, the Company is engaged in a public offering (the “Offering”) of (i) 75,000 units (the “Units”), with each Unit consisting of (A) one share of the Company’s J Convertible Redeemable Preferred Stock, par value $0.001 per share (the “Series J Convertible Preferred Stock”), and (B) one warrant (each a “Preferred Warrant” and collectively, the “Preferred Warrants”) to purchase one-half of one share (0.5) of Series J Convertible Preferred Stock, (ii) the shares of Series J Convertible Preferred Stock issuable upon exercise of the Preferred Warrants (the “Preferred Warrant Shares”), (iii) the shares of Series J Convertible Preferred Stock issuable upon the payment in-kind of dividends (“PIK Dividends”), and (iv) the shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), issuable upon conversion of the Series J Convertible Preferred Stock (the “Conversion Shares”).

WHEREAS, the Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form S-1 (File No. 333-273372) (as the same may be amended from time to time) and a Registration Statement on Form S-1 MEF (File No. 333-274504), together, the “Registration Statements”), for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the Units, the Series J Convertible Preferred Stock, the Preferred Warrants, the Preferred Warrant Shares, the PIK Dividends and the Conversion Shares, and such Registration Statements became effective on September 13, 2023;

WHEREAS, on September 14, 2023, the Company filed with the Delaware Secretary of State a Certificate of Designation of Preferences, Rights and Limitations (the “Certificate of Designation”) that sets forth the terms of such J Convertible Preferred Stock, which includes a liquidation preference of $100.00 per share (“Stated Value”);

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in accordance with the terms set forth in this Warrant Agency Agreement in connection with the issuance, registration, transfer, exchange and exercise of the Preferred Warrants;

WHEREAS, the Company desires to provide for the provisions of the Preferred Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Preferred Warrants, as applicable; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Preferred Warrants the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Warrant Agency Agreement.

1

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company with respect to the Preferred Warrants in accordance with the express terms and conditions hereof, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the express terms and conditions set forth in this Warrant Agency Agreement (and no implied terms or conditions).

2. Warrants. The Preferred Warrants shall be registered securities in book-entry form and shall initially be evidenced by a global certificate in the form of Exhibit A (the “Global Certificate”) attached to this Warrant Agency Agreement, which shall be deposited on behalf of the Company with a custodian for The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., a nominee of DTC. If DTC subsequently ceases to make its book-entry settlement system available for the Preferred Warrants, the Company shall instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Preferred Warrants are not eligible for, or it is no longer necessary to have the Preferred Warrants available in, book-entry form, the Company shall instruct the Warrant Agent to provide written instructions to DTC to deliver to the Warrant Agent for cancellation the Global Certificate or Certificates, and the Company shall instruct the Warrant Agent to deliver to DTC separate certificates evidencing Warrants (“Definitive Certificates” and, together with the Global Certificate, “Preferred Warrant Certificates”) registered as requested through the DTC system. The Definitive Certificates, together with the form of election to purchase shares of Series J Convertible Preferred Stock (the “Notice of Exercise”) and the form of assignment to be printed on the reverse thereof, shall be substantially in the form of Exhibit B attached hereto.

2.1. Issuance and Registration of Preferred Warrants.

2.1.1. Warrant Register. The Warrant Agent shall maintain books (“Warrant Register”) for the registration of original issuance and the registration of transfer of the Preferred Warrants.

2.1.2. Issuance of Preferred Warrants. Upon the initial issuance of the Preferred Warrants, the Warrant Agent shall issue the Global Certificates and deliver the Preferred Warrants in the DTC book-entry settlement system in accordance with written instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Preferred Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained (i) by DTC and (ii) by institutions that have accounts with DTC (each, a “Participant”). A Holder has the right to elect at any time or from time to time a Preferred Warrant Exchange (as defined below) pursuant to a Preferred Warrant Certificate Request Notice (as defined below). Upon written notice by a Holder to the Warrant Agent and the Company for the exchange of some or all of such Holder’s Preferred Warrants held in book-entry form for a Definitive Certificate evidencing the same number of Preferred Warrants, which request shall be in the form attached hereto as Annex A (such notice, the “Preferred Warrant Certificate Request Notice” and the date of delivery of such Preferred Warrant Certificate Request Notice by the Holder, the “Preferred Warrant Certificate Request Notice Date” and the actual surrender upon delivery by the Holder of a number of Preferred Warrants in the DTC book-entry settlement system for the same number of Preferred Warrants evidenced by a Definitive Certificate, a “Preferred Warrant Exchange”), the Warrant Agent shall, as promptly as practicable, effect the Preferred Warrant Exchange and the Company shall promptly issue and deliver (or cause to be delivered) to the Holder a Definitive Certificate for such number of Preferred Warrants in the name set forth in the Preferred Warrant Certificate Request Notice. Such Definitive Certificate shall be dated the original issue date of the Preferred Warrants and shall be executed manually or by facsimile signature by an authorized signatory of the Company and shall be in the form attached hereto as Exhibit B. In connection with a Preferred Warrant Exchange, the Company agrees to deliver, or to direct the Warrant Agent to deliver, the Definitive Certificate to the Holder within three (3) Trading Days of the Preferred Warrant Certificate Request Notice pursuant to the delivery instructions in the Preferred Warrant Certificate Request Notice (“Preferred Warrant Certificate Delivery Date”). If the Company fails for any reason to

2

deliver or cause the delivery to the Holder the Definitive Certificate subject to the Preferred Warrant Certificate Request Notice by the Preferred Warrant Certificate Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Preferred Warrant Shares evidenced by such Definitive Certificate (based on the Stated Value of the Series J Convertible Preferred Stock, as set forth in the Certificate of Designation), of the Series J Convertible Preferred Stock on the Preferred Warrant Certificate Request Notice Date), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading Day after the Preferred Warrant Share Delivery Date) for each Trading Day after such Preferred Warrant Certificate Delivery Date until such Definitive Certificate is delivered or, prior to delivery of such Preferred Warrant Certificate, the Holder rescinds such Preferred Warrant Exchange. Notwithstanding the forgoing, the Warrant Agent shall not, in any event, be subject to, or responsible for, liquidated damages or any “buy-in” penalties or any other amounts payable or paid to any Holder or any other Person for any failure or delay to deliver the Definitive Certificate as aforesaid. In addition, the Company shall indemnify and hold harmless the Warrant Agent against any claims made against the Warrant Agent for any such failure. The Company covenants and agrees that, upon the date of delivery of the Preferred Warrant Certificate Request Notice, the Holder shall be deemed to be the holder of the Definitive Certificate and, notwithstanding anything to the contrary set forth herein, the Definitive Certificate shall be deemed for all purposes to contain all of the terms and conditions of the Preferred Warrants evidenced by such Definitive Certificate and the terms of this Warrant Agency Agreement. A party requesting a Preferred Warrant Exchange must provide to the Warrant Agent any evidence of authority that may reasonably be required by the Warrant Agent, including but not limited to, a signature guarantee.

2.1.3. Beneficial Owner; Holder. Prior to due presentment for registration of transfer of any Preferred Warrant, the Company and the Warrant Agent shall deem and treat the person in whose name that Preferred Warrant shall be registered on the Warrant Register (the “Holder”) as the absolute owner of such Preferred Warrant for purposes of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Warrant Agent or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished by DTC governing the exercise of the rights of a holder of a beneficial interest in any Preferred Warrant. The rights of beneficial owners in a Preferred Warrant evidenced by the Global Certificate shall be exercised by the Holder or a Participant through the DTC system, except to the extent set forth herein or in the Global Certificate.

2.1.4. Execution. The Preferred Warrant Certificates shall be executed on behalf of the Company by any authorized officer of the Company (an “Authorized Officer”), which need not be the same authorized signatory for all of the Preferred Warrant Certificates, either manually or by facsimile signature. The Preferred Warrant Certificates shall be countersigned, either manually or by facsimile signature, by an authorized signatory of the Warrant Agent, which need not be the same signatory for all of the Preferred Warrant Certificates, and no Preferred Warrant Certificate shall be valid for any purpose unless so countersigned. In case any Authorized Officer of the Company that signed any of the Preferred Warrant Certificates ceases to be an Authorized Officer of the Company before countersignature by the Warrant Agent and issuance and delivery by the Company, such Preferred Warrant Certificates, nevertheless, may be countersigned by the Warrant Agent, issued and delivered with the same force and effect as though the person who signed such Preferred Warrant Certificates had not ceased to be such officer of the Company; and any Preferred Warrant Certificate may be signed on behalf of the Company by any other person who, at the actual date of the execution of such Preferred Warrant Certificate, shall be an Authorized Officer of the Company authorized to sign such Preferred Warrant Certificate, although at the date of the execution of this Warrant Agency Agreement any such person was not such an Authorized Officer.

3

2.1.5. Registration of Transfer. Subject to the provisions of the Preferred Warrants, at any time prior to 5:00 p.m. (New York City time) on the Termination Date (as defined below), a transfer of any Preferred Warrants may be registered and any Preferred Warrant Certificate or Preferred Warrant Certificates may be split up, combined or exchanged for another Preferred Warrant Certificate or Preferred Warrant Certificates evidencing the same number of Preferred Warrants as the Preferred Warrant Certificate or Preferred Warrant Certificates surrendered. Any Holder desiring to register the transfer of Preferred Warrants or to split up, combine or exchange any Preferred Warrant Certificate shall make such request in writing delivered to the Warrant Agent, and shall surrender to the Warrant Agent the Preferred Warrant Certificate or Preferred Warrant Certificates evidencing the Preferred Warrants the transfer of which is to be registered or that is or are to be split up, combined or exchanged together with any required form of assignment and certificate duly executed and properly completed by such Holder at the office or offices of the Warrant Agent designated for such purpose and, in the case of registration of transfer, shall provide a signature guarantee (a “signature guarantee”) from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association and such other documentation as the Warrant Agent may reasonably request. Thereupon, the Warrant Agent shall countersign and deliver to the person entitled thereto a Preferred Warrant Certificate or Preferred Warrant Certificates, as the case may be, as so requested. The Company and the Warrant Agent may require payment, by the Holder requesting a registration of transfer of Preferred Warrants or a split-up, combination or exchange of a Preferred Warrant Certificate (but, for purposes of clarity, not upon the exercise of the Preferred Warrants and issuance of Preferred Warrant Shares to the Holder), of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with such registration of transfer, split-up, combination or exchange, together with reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto. The Warrant Agent shall not have any duty or obligation to take any action under any section of this Warrant Agreement that requires the payment of taxes and/or charges unless and until it is satisfied that all such payments have been made.

2.1.6. Loss, Theft and Mutilation of Warrant Certificates. Upon receipt by the Company and the Warrant Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Preferred Warrant Certificate, which evidence shall include an affidavit of loss, or in the case of mutilated certificates, the certificate or portion thereof remaining, and, in case of loss, theft or destruction, of indemnity or security in customary form and amount satisfactory to the Warrant Agent, and satisfaction of any other reasonable requirements, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto, and upon surrender to the Warrant Agent and cancellation of the Preferred Warrant Certificate if mutilated, the Company shall make and deliver a new Warrant Certificate of like tenor to the Warrant Agent for countersignature and delivery to the Holder in lieu of the Preferred Warrant Certificate so lost, stolen, destroyed or mutilated. The Warrant Agent may charge the Holder an administrative fee for processing the replacement of lost Warrant Certificates, which shall be charged only once in instances where a single surety bond obtained covers multiple certificates. The Warrant Agent may receive compensation from the surety companies or surety agents for administrative services provided to them.

2.1.7. Proxies. The Holder of a Preferred Warrant may grant proxies or otherwise authorize any person, including the Participants and beneficial holders that may own interests through the Participants, to take any action that a Holder is entitled to take under this Warrant Agency Agreement or the Preferred Warrants; provided, however, that at all times that Preferred Warrants are evidenced by a Global Certificate, exercise of those Warrants shall be effected on their behalf by Participants through DTC in accordance the procedures administered by DTC.

2.1.8. Opinion of Counsel. On or prior to the execution of this Warrant Agency Agreement, the Company shall provide the Warrant Agent with an opinion of counsel to set up a reserve of Preferred Warrant Shares for the outstanding Preferred Warrants. The opinion shall state that all Preferred Warrants

4

or Preferred Warrant Shares, as applicable, are (a) registered under the Securities Act of 1933, as amended (the “Securities Act”), or are exempt from such registration, and all appropriate state securities law filings have been made with respect to the warrants or shares or alternatively, that the securities are “covered securities” under Section 18 of the Securities Act; and (b) validly issued, fully paid and non-assessable.3. Terms and Exercise of Preferred Warrants.

3.1. Exercise Price. Each Preferred Warrant shall entitle the Holder, subject to the provisions of the applicable Preferred Warrant Certificate and of this Warrant Agency Agreement, to purchase from the Company the number of shares of Series J Convertible Preferred Stock, stated therein, at the exercise price of $60.00 per whole share (or $30.00 per one-half of one (0.5) share), subject to the subsequent adjustments provided by Section 4 hereof and Section 3 of the Preferred Warrant Certificates. The term “Exercise Price” as used in this Warrant Agency Agreement refers to the price per share at which shares of Series J Convertible Preferred Stock, may be purchased at the time a Preferred Warrant is exercised.

3.2. Duration of Preferred Warrants. The Preferred Warrants have a one-year term and may be exercised only during the period (“Exercise Period”) commencing on or after September 18, 2023 and ending on 5:00 p.m. (New York City time) on September 18, 2024 (the “Termination Date”). Each Preferred Warrant not exercised before 5:00 p.m. (New York City time) on the Termination Date shall become void, and, subject to Sections 7.11 and 9.5 hereof, all rights thereunder and all rights in respect thereof under this Warrant Agency Agreement shall cease at the close of business on the Termination Date.

3.3. Exercise of Preferred Warrants.

3.3.1. Exercise and Payment. (a) Subject to the provisions of this Warrant Agency Agreement, a Holder of a Definitive Certificate may exercise Preferred Warrants evidenced by such Definitive Certificate by delivering to the Warrant Agent and the Company, a duly executed facsimile copy or PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed to the Preferred Warrant Certificate. Notwithstanding any other provision in this Warrant Agency Agreement, a holder whose interest in a Preferred Warrant is a beneficial interest in a Global Certificate held in book-entry form through DTC (or another established clearing corporation performing similar functions), shall effect exercises by delivering to DTC (or such other clearing corporation, as applicable) the appropriate instruction form for exercise, complying with the procedures to effect exercise that are required by DTC (or such other clearing corporation, as applicable). Any Holder exercising a Preferred Warrant shall deliver payment of the Exercise Price pursuant to Section 2(a) and Section 2(b) of the Preferred Warrant Certificate set forth in Exhibit B attached hereto. The Warrant Agent shall forward funds received for Preferred Warrant exercises by the fifth Business Day of the following month after such funds are received by the Warrant Agent by wire transfer to an account designated by the Company. The Company acknowledges that the bank accounts maintained by the Warrant Agent in connection with the services provided under this Warrant Agency Agreement will be in Computershare’s name, as agent for the Company, and that the Warrant Agent may receive investment earnings in connection with the investment at Warrant Agent risk and for its benefit of funds (the “Funds”) held in those accounts from time to time. Until paid pursuant to the terms of this Warrant Agency Agreement, Computershare will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). Computershare shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made by Computershare in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other third party. Computershare may from time to time receive interest, dividends or other earnings in connection with such deposits. Computershare shall not be obligated to pay such interest, dividends or earnings to the Company, any holder or any other party. If either the Exercise Note or the Exercise price relating to an exercise are received or deemed to be received after the Termination

5

Date, the exercise thereof will be null and void and any funds delivered to the Company will be returned to the Holder or Participant, as the case may be, as soon as practicable. In no event will interest accrue on any funds deposited with the Company in respect of an exercise or attempted exercise of the Preferred Warrants. (b) The Preferred Warrants shall cease to be exercisable and shall terminate and become void and callable as set forth in the applicable Preferred Warrant Certificate. The Company hereby instructs the Warrant Agent to record cost basis for newly issued shares in a manner to be subsequently communicated by the Company in writing to the Warrant Agent.

3.3.2. Issuance of Preferred Warrant Shares.

(a) The Warrant Agent shall, as promptly as practicable following the date of exercise of any Preferred Warrant, advise the Company (to the extent known the Warrant Agent) and the transfer agent and registrar for the Company’s Series J Convertible Preferred Stock, which on the date hereof is Computershare Trust Company, N.A (the “Transfer Agent”), in respect of (i) the number of Preferred Warrant Shares indicated on the Notice of Exercise as issuable upon such exercise with respect to such exercised Warrants, (ii) the instructions of the Holder or Participant, as the case may be, provided to the Warrant Agent with respect to the delivery of the Preferred Warrant Shares and the number of Preferred Warrants that remain. outstanding after such exercise, and (iii) such other information as the Company or the Transfer Agent shall reasonably request.

(b) Upon the Warrant Agent’s receipt, at or prior to the Close of Business on the Termination Date set forth in a Preferred Warrant Certificate, of the executed Notice of Exercise, accompanied by payment of the Exercise Price pursuant to Section 2(a) and 2(b) of the Preferred Warrant Certificate set forth in Exhibit B attached hereto, the Warrant Agent shall cause the Preferred Warrant Shares underlying such Preferred Warrant to be delivered by the Transfer Agent to or upon the order of the Holder of such Preferred Warrant, registered in such name or names as may be designated by such Holder, no later than the Preferred Warrant Share Delivery Date. If the Company is then a participant in DTC’s Deposit or Withdrawal at Custodian (“DWAC”) system and there is an effective registration statement permitting the issuance of the Preferred Warrant Shares to or resale of the Preferred Warrant Shares by Holder, then the Company shall cause the Preferred Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s account with DTC through its Deposit or Withdrawal at Custodian system.

3.3.3. Valid Issuance. All Preferred Warrant Shares issued by the Company upon the proper exercise of a Preferred Warrant in conformity with this Warrant Agency Agreement shall be validly issued, fully paid and non-assessable.

3.3.4. No Fractional Shares or Scrip. Notwithstanding any provision to the contrary contained in this Agreement or the Preferred Warrant, the Company shall not be required to issue any fraction of a Preferred Warrant Share or scrip representing fractional shares upon the exercise of the Preferred Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Stated Value of the Series J Convertible Preferred Stock, as set forth in the Series J Certificate of Designation. Accordingly, a holder of a Preferred Warrant is entitled to exercise a number of Preferred Warrants that would result solely in the holder receiving one or more whole Preferred Warrant Shares. Prior to paying an adjustment in cash in respect of a fractional interest, the Company shall first provide to Computershare an initial funding of one thousand dollars ($1,000) for the purpose of issuing cash in lieu of fractional shares. From time to time thereafter, Computershare may request additional funding to cover fractional payments. Computershare shall have no obligation to make fractional payments unless the Company shall have provided the necessary funds to pay in full all amounts due and payable with respect thereto.3.3.5. Charges, Taxes, and Expenses. Issuance of Preferred Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of

6

such Preferred Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Preferred Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Preferred Warrant Shares are to be issued in a name other than the name of the Holder, the Preferred Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached to the Preferred Warrant properly completed and duly executed by the Holder and accompanied by a signature guarantee and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto; and (the Company shall use its best efforts to pay, or procure payment of issue or stamp taxes levied in connection with the issuance of the Preferred Warrant or Preferred Warrant Shares to the Holder (“Relevant Taxes”). The Holder agrees to cooperate with the Company and provide all necessary and reasonable information and documentation to the Company in a timely manner (and in any event within 10 Business Days of request) to enable the Company to procure payment of any Relevant Taxes and facilitate the making of any necessary filings in respect of Relevant Taxes required to be made within applicable time limits. The Company shall not be liable for any Relevant Taxes or any penalty, fine, surcharge, interest, charge, cost or other similar imposition arising in respect of Relevant Taxes to the extent that such amount arises or is increased as a result of any failure by a Holder to timely provide the Company with any information or documentation reasonably requested pursuant to Section 2(d)(vi) of the Preferred Warrant Certificate set forth in Exhibit B attached hereto. The Company shall pay all Transfer Agent fees required for processing of any Notice of Exercise and all fees to DTC (or another established clearing corporation performing similar functions) required for electronic delivery of the Preferred Warrant Shares.

3.3.6. Date of Issuance. The Company will treat an exercising Holder as a beneficial owner of the Preferred Warrant Shares as of the date of exercise of any Preferred Warrant, except that, if such date of exercise is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the open of business on the next succeeding date on which the stock transfer books are open.

3.3.7. [Reserved].

3.3.8. [Reserved].

3.3.9. Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Preferred Warrant Shares issuable in connection with any exercise, the Company shall promptly deliver to the Holder the number of Preferred Warrant Shares that are not disputed.

4. Adjustments. The Exercise Price, the number of shares of Series J Convertible Preferred Stock covered by each Preferred Warrant and the number of Preferred Warrants outstanding are subject to adjustment from time to time as provided in Section 3 of the Preferred Warrant Certificate set forth in Exhibit B attached hereto. The Company hereby agrees that it will provide the Warrant Agent with reasonable notice of any such adjustments. The Warrant Agent shall have no obligation under any Section of this Agreement to determine whether an event resulting in any such adjustment has occurred or to calculate any of the adjustments set forth herein. All Preferred Warrants originally issued by the Company subsequent to any adjustment made to the Exercise Price pursuant to the Warrant shall evidence the right to purchase, at the adjusted Exercise Price, the number of shares of Series J Convertible Preferred Stock, purchasable from time to time hereunder upon exercise of the Preferred Warrants, all subject to further adjustment as provided herein. Whenever the Exercise Price or the number of Preferred Warrant Shares issuable upon the exercise of each Preferred Warrant is adjusted, the Company shall (a) promptly prepare a certificate setting forth the Exercise Price of each Preferred Warrant as so adjusted and the increase or decrease, if any, in the number of Preferred Warrant Shares purchasable at such price upon the exercise of a Preferred Warrant, and a brief statement of the facts accounting for such adjustment, (b) promptly file

7

with the Warrant Agent and with the Transfer Agent a copy of such certificate and (c) instruct the Warrant Agent to send a brief summary thereof to each Holder of a Preferred Warrant. If the Company requests the Warrant Agent to send such notices, it shall provide the Warrant Agent with a draft notice to be used for this purpose. The Warrant Agent shall be entitled to rely conclusively on, and shall be fully protected in relying on, any certificate, notice or instructions provided by the Company with respect to any adjustment of the Exercise Price or the number of shares issuable upon exercise of a Preferred Warrant, or any related matter, and the Warrant Agent shall not be liable for any action taken, suffered or omitted to be taken by it in accordance with any such certificate, notice or instructions or pursuant to this Warrant Agency Agreement. The Warrant Agent shall not be deemed to have knowledge of any such adjustment unless and until it shall have received written notice thereof from the Company.

5. Restrictive Legends; Fractional Warrants. In the event that a Preferred Warrant Certificate surrendered for transfer bears a restrictive legend, the Warrant Agent shall not register that transfer until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the Preferred Warrants must also bear a restrictive legend upon that transfer. The Company shall not issue fractions of Preferred Warrants or distribute a Global Certificate or Warrant Certificates that evidence fractional Warrants. Whenever any fractional Warrant would otherwise be required to be issued or distributed, the actual issuance or distribution shall be paid via a cash adjustment as set forth in Section 3.3.4 of this Agreement. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the transfer of or delivery of a Preferred Warrant Certificate for a fraction of a Preferred Warrant. The Company shall not issue fractions of shares of Series J Convertible Preferred Stock upon exercise of Preferred Warrants or distribute stock certificates that evidence fractional shares of Series J Convertible Preferred Stock. Whenever any fraction of a share of Series J Convertible Preferred Stock would otherwise be required to be issued or distributed, the actual issuance or distribution in respect thereof shall be made in accordance with Section 2(d)(v) of the Preferred Warrant Certificate attached hereto as Exhibit B.

6. Other Provisions Relating to Rights of Holders of Preferred Warrants.

6.1. No Rights as Stockholder. Except as otherwise specifically provided herein and in accordance with the Preferred Warrant Certificates, a Holder, solely in his, her or its capacity as a holder of Preferred Warrants, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant Agency Agreement be construed to confer upon a Holder, solely in its capacity as the registered holder of Preferred Warrants, any of the rights of a shareholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of share capital, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights or rights to participate in new issues of shares, or otherwise, prior to the issuance to the Holder of the Preferred Warrant Shares which it is then entitled to receive upon the due exercise of Preferred Warrants.

6.2. Reservation of Series J Convertible Preferred Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Series J Convertible Preferred Stock pursuant to this Agreement and Section 6(d) of the Preferred Warrant Certificate attached hereto as Exhibit B.

7. Conditions of the Warrant Agent’s Obligations. The Warrant Agent accepts its obligations herein set forth upon the express terms and conditions hereof, including the following to all of which the Company agrees and to all of which the rights hereunder of the Holders from time to time shall be subject:7.1. Compensation and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation set forth in a mutually agreed upon fee schedule executed on or before the date hereof for all services rendered by the Warrant Agent and on demand of the Warrant Agent to reimburse the

8

Warrant Agent for reasonable out-of-pocket expenses (including reasonable counsel fees) and other disbursements incurred in the preparation, delivery, negotiation, amendment, administration and execution of this Warrant Agency Agreement and the exercise and performance of its duties hereunder. The Company covenants and agrees to indemnify and to hold harmless the Rights Agent against, any and all loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense (including, without limitation, the reasonable and documented fees and expenses of legal counsel) that may be paid, incurred or suffered by it, or which it may become subject, without gross negligence, bad faith or willful misconduct on the part of the Warrant Agent (which gross negligence, bad faith, or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction), for any action taken, suffered, or omitted to be taken by the Warrant Agent in connection with the execution, acceptance, administration, exercise and performance of its duties under this Warrant Agency Agreement, including the reasonable and documented costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights hereunder. The Warrant Agent shall not be liable for the Company’s failure to timely deliver Preferred Warrant Shares pursuant to the terms of the Preferred Warrants, nor shall the Warrant Agent be liable for any liquidated damages or any other damages associated therewith.

9.1. Whenever in the performance of its duties under this Warrant Agency Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chief Executive Officer, Chief Financial Officer, General Counsel or Secretary of the Company; and such certificate shall be full authentication to the Warrant Agent and the Warrant Agent shall be fully protected and shall no incur no liability for any action taken, suffered or omitted to be taken by it under the provisions of this Warrant Agency Agreement in reliance upon such certificate in the absence of bad faith.

9.2. Subject to the limitation set forth in Section 7.12 of this Warrant Agency Agreement, the Warrant Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct (which gross negligence, bad faith, or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction).

11

9.3. The Warrant Agent is hereby authorized to accept instructions with respect to the performance of its duties hereunder from the Chief Executive Officer, Chief Financial Officer, General Counsel or Secretary of the Company, and to apply to such officers for advice or instructions with respect to any matter arising in connection with the services to be performed by the Warrant Agent under this Warrant Agency Agreement, and it shall not be liable and shall be indemnified and held harmless by the Company for any action taken, suffered or omitted to be taken by it in the absence of bad faith in accordance with instructions of any such officer, provided Warrant Agent carries out such instructions without gross negligence, bad faith or willful misconduct (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgement of a court of competent jurisdiction).

9.4. The Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorney or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorney or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

9.5. This Section 9 shall survive the exercise or expiration of the Preferred Warrants, the termination of this Warrant Agency Agreement and the resignation, replacement or removal of the Warrant Agent.

10. Change of Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign and be discharged from its duties under this Warrant Agency Agreement upon 30 days’ notice in writing sent to the Company, and in the event that the Warrant Agent or one of its affiliates is not also the transfer agent for the Series J Convertible Preferred Stock, to each transfer agent of the Series J Convertible Preferred Stock known to the Warrant Agent, and to the Holders of record of the Preferred Warrant Certificates. In the event the transfer agency relationship in effect between the Company and the Warrant Agent terminates, the Warrant Agent will be deemed to have resigned automatically and be discharged from its duties under this Warrant Agency Agreement as of the effective date of such termination, and the Company shall be responsible for sending any required notice. The Company may remove the Warrant Agent or any successor Warrant Agent upon 30 days’ notice in writing, sent to the Warrant Agent or successor Warrant Agent, as the case may be, and to each transfer agent of the Common Stock, and to the Holders of the Preferred Warrant Certificates. If the Warrant Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Warrant Agent or by the Holder of a Preferred Warrant Certificate (who shall, with such notice, submit his Warrant Certificate for inspection by the Company), then the Holder of any Preferred Warrant Certificate may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent, provided that, for purposes of this Warrant Agency Agreement, the Company shall be deemed to be the Warrant Agent until a new warrant agent is appointed. Any successor Warrant Agent, whether appointed by the Company or by such a court, shall be an entity organized and doing business under the laws of the United States or of a state thereof, in good standing, which is authorized under such laws to exercise stock transfer powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Warrant Agent a combined capital and surplus (together with its affiliates) of at least $50,000,000. After appointment, the successor Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Warrant Agent without further act or deed; but the predecessor Warrant Agent shall deliver and transfer to the successor Warrant Agent any property at the time held by it hereunder and execute and deliver, at the expense of the Company, any further assurance, conveyance, act or deed necessary for such purpose without assumption of any liability on the part of the former Warrant Agent. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Warrant Agent and each transfer agent of the

12

Common Stock, and mail or other deliver a notice thereof in writing to the Holders of the Preferred Warrant Certificates. However, failure to give any notice provided for in this Section 9, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Warrant Agent or the appointment of the successor Warrant Agent, as the case may be.

11. Issuance of New Warrant Certificates. Notwithstanding any of the provisions of this Warrant Agency Agreement or of the Preferred Warrants to the contrary, the Company may, at its option, issue new Preferred Warrant Certificates evidencing Preferred Warrants in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Exercise Price per share and the number or kind or class of shares of stock or other securities or property purchasable under the several Preferred Warrant Certificates made in accordance with the provisions of this Warrant Agency Agreement.

12. Notices. Notices or demands authorized by this Warrant Agency Agreement to be given or made (i) by the Warrant Agent or by the Holder of any Preferred Warrant Certificate to or on the Company, (ii) subject to the provisions of Section 10, by the Company or by the Holder of any Preferred Warrant Certificate to or on the Warrant Agent or (iii) by the Company or the Warrant Agent to the Holder of any Preferred Warrant Certificate, shall be deemed given (a) on the date delivered, if delivered personally, (b) when deposited with Federal Express or another recognized overnight courier, if sent by Federal Express or another recognized overnight courier, (c) when mailed with postage prepaid, if mailed by registered or certified mail (return receipt requested), and (d) the date of transmission, if such notice or communication is delivered via facsimile (with confirmation) or email attachment (other than to the Warrant Agent) at or prior to 5:30 p.m. (New York City time) on a Business Day and (e) the next Business Day after the date of transmission, if such notice or communication is delivered via facsimile (with confirmation) or email attachment (other than to the Warrant Agent) on a day that is not a Business Day or later than 5:30 p.m. (New York City time) on any Business Day, in each case to the parties at the following addresses (or at such other address for a party as shall be specified by like notice):

Section 2. Exercise.

a) Exercise of Warrant. Subject to the provisions of Section 2(e) hereof, exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and prior to 5:00 p.m. (New York City time) on the Termination Date by delivery to the Warrant Agent and the Company of a duly executed PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”). Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the Preferred Warrant Shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank. Neither the Company nor the Warrant Agent shall have any obligation to inquire with respect to or otherwise confirm the authenticity of the signature(s) contained on any Notice of Exercise nor the authority of the person so executing such Notice of Exercise. No ink original Notice of Exercise shall be required nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company or the Warrant Agent until the Holder has subscribed for all of the Preferred Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Warrant Agent for cancellation within three (3) Trading Days after the date on which the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in subscriptions for a portion of the total number of Preferred Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Preferred Warrant Shares issuable hereunder in an amount equal to the applicable number of Preferred Warrant Shares subscribed for. The Holder and the Warrant Agent shall maintain records showing the number of Preferred Warrant Shares subscribed for and the date of such purchase. The Company shall deliver to the Holder and Warrant Agent any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase for a portion of the Preferred Warrant Shares hereunder, the number of Preferred Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

Notwithstanding the foregoing in this Section 2(a), a holder whose interest in this Warrant is a beneficial interest in certificate(s) representing this Warrant held in book-entry form through DTC (or another established clearing corporation performing similar functions), shall effect exercises made pursuant to this Section 2(a) by delivering to DTC (or such other clearing corporation, as applicable) the appropriate instruction form for exercise, complying with the procedures to effect exercise that are required by DTC (or such other clearing corporation, as applicable), subject to a Holder’s right to elect to receive a Warrant in certificated form pursuant to the terms of the Warrant Agency Agreement, in which case this sentence shall not apply.

3

b) Exercise Price. The exercise price per one-half of one (0.5) share of Series J Preferred Stock under this Warrant shall be $30.00, subject to adjustment hereunder (the “Exercise Price”).

c) [Reserved].

d) Mechanics of Exercise.

i. Delivery of Preferred Warrant Shares Upon Exercise. The Company shall cause the Preferred Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with DTC through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and there is an effective registration statement permitting the issuance of the Preferred Warrant Shares to the Holder, and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Preferred Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company and the Warrant Agent of the Notice of Exercise, provided that payment of the aggregate Exercise Price is received by the Warrant Agent one (1) Trading Day prior to such second Trading Day after the delivery of the Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Warrant Agent and (iii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company and Warrant Agent of the Notice of Exercise, provided that payment of the aggregate Exercise Price is received by the Warrant Agent one (1) Trading Day prior to such second Trading Day after the delivery of the Notice of Exercise (such date, the “Warrant Share Delivery Date” and such conditions, the “Exercise Conditions”). For the purposes of Regulation SHO under the Exchange Act, upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Preferred Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Preferred Warrant Shares, provided that payment of the aggregate Exercise Price is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. If the Company fails for any reason to deliver or cause the delivery to the Holder the Preferred Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Preferred Warrant Shares subject to such exercise (based on the stated value of the Series J Preferred Stock, as set forth in the Series J Certificate of Designation), $10.00 per Trading Day (increasing to $20.00 per Trading Day on the fifth Trading Day after the Warrant Share Delivery Date) for each Trading Day after such Warrant Share Delivery Date until such Preferred Warrant Shares are delivered or the Holder rescinds such exercise; provided, however, that the Holders may convert the Preferred Warrant Shares into shares of Common Stock in accordance with the terms of the Series J Certificate of Designation at any time, at the option of the Holder, following its satisfaction of the applicable Exercise Conditions (such conversion, a “Forced Conversion”). In the event of a Forced Conversion, the liquidated damages referred to in the preceding sentence shall cease to accrue under this Warrant on the date that shares of Common Stock are delivered to the Holder pursuant to the Series J Certificate of Designation. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market as in effect on the date of delivery of the Notice of Exercise. In addition, notwithstanding the foregoing, a Holder may convert the shares of Series J Preferred Stock subject to the Notice of Exercise into Conversion Shares (as defined in the Series J Certificate of Designation) pursuant to the Series J Certificate of Designation by

4

simultaneously delivering the Notice of Exercise and a Notice of Conversion (as defined in the Series J Certificate of Designation) to the Company thereunder, and upon the delivery of said Notice of Conversion, the Company shall deliver, or cause to be delivered, to the converting Holder the applicable number of Conversion Shares subject to the Notice of Conversion by the Share Delivery Date (as defined in the Series J Certificate of Designation).

ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Preferred Warrant Shares, cause the Warrant Agent to deliver to the Holder a new Warrant evidencing the rights of the Holder to subscribe for the unsubscribed for Preferred Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii. Rescission Rights and Forced Conversion. If the Company fails to cause the Transfer Agent to transmit to the Holder the Preferred Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise or effect a Forced Conversion by delivering written notice to the Company at any time prior to the delivery of such Preferred Warrant Shares (in which case any liquidated damages payable under Section 2(d)(i) shall no longer be payable).

iv. Compensation for Buy-In on Failure to Timely Deliver Preferred Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Preferred Warrant Shares in accordance with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date (so long as the Company has provided wire transfer instructions to the Holder on Company letterhead signed by an executive officer of the Company, other than as a result of failure of the Holder to timely deliver the aggregate Exercise Price or a failure that is solely due to any action or inaction by the Holder with respect to such exercise), and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Series J Preferred Stock to deliver in satisfaction of a sale by the Holder of the Preferred Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Series J Preferred Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Preferred Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Preferred Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Series J Preferred Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases shares of Series J Preferred Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of this Warrant to subscribe for shares of Series J Preferred Stock with an aggregate exercise price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Series J Preferred Stock upon exercise of the Warrant as required pursuant to the terms hereof.

v. No Fractional Shares or Scrip. Notwithstanding any provision to the contrary contained in this Warrant, the Company shall not be required to issue any fraction of a Preferred Warrant Shares or scrip representing fractional shares of Preferred Warrant Shares upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the stated value of the Series J Preferred Stock, as set forth in the Series J Certificate of Designation. Accordingly, a Holder is entitled to exercise a number of Warrants that would solely result in the Holder receiving one or more whole Warrant Shares.

5

vi. Charges, Taxes and Expenses. Issuance of Preferred Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Preferred Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Preferred Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Preferred Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto; and (ii) the Company shall use its best efforts to pay, or procure payment of issue or stamp taxes levied in connection with the issuance of the Warrant or Preferred Warrant Shares to the Holder (“Relevant Taxes”). The Holder agrees to cooperate with the Company and provide all necessary and reasonable information and documentation to the Company in a timely manner (and in any event within 10 Business Days of request) to enable the Company to procure payment of any Relevant Taxes and facilitate the making of any necessary filings in respect of Relevant Taxes required to be made within applicable time limits. The Company shall not be liable for any Relevant Taxes or any penalty, fine, surcharge, interest, charge, cost or other similar imposition arising in respect of Relevant Taxes to the extent that such amount arises or is increased as a result of any failure by a Holder to timely provide the Company with any information or documentation reasonably requested pursuant to this Section 2(d)(vi). The Company shall pay all Transfer Agent fees required for processing of any Notice of Exercise and all fees to DTC (or another established clearing corporation performing similar functions) required for electronic delivery of the Preferred Warrant Shares.

vii. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

e) [Reserved].

f) [Reserved].

Section 3. Certain Adjustments.

a) Share Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a share dividend or otherwise makes a distribution or distributions on its Series J Preferred Stock or any other security of the Company that may be converted into Series J Preferred Stock (which, for avoidance of doubt, shall not include any shares of Series J Preferred Stock issued by the Company upon exercise of this Warrant and shall not include any of the dividends to be paid to holders of shares of Series J Preferred Stock pursuant to Section 3 of the Series J Preferred Stock Certificate of Designation), (ii) subdivides outstanding shares of Series J Preferred Stock into a larger number of shares, (iii) combines (including by way of reverse share split) outstanding shares of Series J Preferred Stock into a smaller number of shares, or (iv) issues by reclassification of shares of Series J Preferred Stock any share capital of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Series J Preferred Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Series J Preferred Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and, in the case of a subdivision, combination or re-classification, shall become effective immediately after the effective date of such subdivision, combination or re-classification.

6

b) [Reserved].

c) Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time that this Warrant is outstanding the Company grants, issues or sells any Preferred Stock Equivalents or rights to purchase shares, warrants, securities or other property pro rata to all of the record holders of the Series J Preferred Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Series J Preferred Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the record date for the grant, issuance or sale of such Purchase Rights, or, if no such record date is established, the date as of which the record holders of shares of Series J Preferred Stock are to be determined for the grant, issue or sale of such Purchase Rights.

d) Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Series J Preferred Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, share or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (except to the extent an adjustment was already made pursuant to Section 3(a)) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Series J Preferred Stock acquirable upon complete exercise of this Warrant immediately before the record date for such Distribution, or, if no such record date is established, the date as of which the record holders of shares of Series J Preferred Stock are to be determined for the participation in such Distribution. Any Distribution or Distributions to be paid to any Holder under this Section 3(d) arising as a result of the Company’s obligation to issue in-kind dividends on the Series J Preferred Stock pursuant to the Certificate of Designation, shall be held in trust for the benefit of the Holder holding the Warrant at the time of exercise of the Warrant, and paid to such Holder only upon such exercise.

e) Fundamental Transaction.

i. Fundamental Transactions. If, at any time while this Warrant is outstanding, a Fundamental Transaction occurs, the Company shall cause any Successor Entity in a Fundamental Transaction in which the Company is not the survivor to assume in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 3(e) pursuant to written agreements prior to such Fundamental Transaction, including agreements to deliver to the Holder, at the Holder’s option, in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number of shares of capital stock equivalent to the shares of Series J Preferred Stock acquirable and receivable upon exercise of this Warrant prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Series J Preferred Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction). Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring

7

to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. In addition to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon an exercise of this Warrant and conversion of the underlying Preferred Warrant Shares at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the Warrant and conversion of the underlying Preferred Warrant Shares prior to such Fundamental Transaction, such shares of stock or securities which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised and converted into Preferred Warrant Shares immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant).

ii. The Company shall instruct the Warrant Agent in writing to mail, by first class mail, postage prepaid, to each Holder, written notice of the execution of any such amendment, supplement or agreement with the Successor Entity. Any supplemented or amended agreement entered into by the Successor Entity shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 3(e). The Warrant Agent shall have no duty, responsibility or obligation to determine the correctness of any provisions contained in such agreement or such notice, including but not limited to any provisions relating either to the kind or amount of securities or other property receivable upon exercise of warrants or with respect to the method employed and provided therein for any adjustments, and shall be entitled to rely conclusively for all purposes upon the provisions contained in any such agreement. The provisions of this Section 3(e) shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales and conveyances of the kind described above.

f) Calculations. All calculations under this Section 3 shall be made by the Company to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Series J Preferred Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Series J Preferred Stock (excluding treasury shares, if any) issued and outstanding.

g) Notice to Holder.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder and to the Warrant Agent by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Preferred Warrant Shares and setting forth a brief statement of the facts requiring such adjustment; provided, however, that the Company may satisfy the notice requirement with respect to the Holder (but not the Warrant Agent) in this Section 3(g) by filing such information with the Commission on its EDGAR system pursuant to a Current Report on Form 8-K or Quarterly Report on Form 10-Q or Annual Report on Form 10-K.

ii. Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form other than a stock split) on the Series J Preferred Stock, except for any recurring cash dividend, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Series J Preferred Stock (excluding any granting or issuance of rights to all of the Company’s stockholders pursuant to a stockholder rights plan), (C) the Company shall authorize the granting to all holders of the Series J Preferred Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company

8

shall be required in connection with any reclassification of the Series J Preferred Stock other than a reverse stock split, any consolidation or merger to which the Company (and its Subsidiaries, taken as a whole) is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Series J Preferred Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least five (5) calendar days prior to the applicable record or effective date hereinafter specified, (unless such information is filed with the Commission on its EDGAR system in which case a notice shall not be required) a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Series J Preferred Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Series J Preferred Stock of record shall be entitled to exchange their shares of Series J Preferred Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4. Transfer of Warrant.

a) Transferability. This Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant at the office of the Warrant Agent designated for such purpose, together with a written assignment of this Warrant substantially in the form attached hereto properly completed and duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer accompanied by reasonable evidence of authority of the party making such request that may be required by the Warrant Agent including but not limited to, the signature guarantee of a guarantor institution which is a participant in a signature guarantee program approved by the Securities Transfer Association. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Preferred Warrant Shares without having a new Warrant issued.

b) New Warrants. If this Warrant is not held in global form through DTC, this Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a) herein and Section 2.1.5 of the Warrant Agreement, as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Issuance Date and shall be identical with this Warrant except as to the number of Preferred Warrant Shares issuable pursuant thereto.

9

c) Warrant Register. The Warrant Agent shall register this Warrant, upon records to be maintained by the Warrant Agent for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company and the Warrant Agent may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary. Notwithstanding the foregoing, nothing herein shall prevent the Warrant Agent or any agent of the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished by DTC or any other depository governing the exercise of the rights of a holder of a beneficial interest in any Warrant. The rights of beneficial owners in a Warrant held in global shall be exercised by the Holder or a Participant (as defined in the Warrant Agency Agreement) through the depository’s system, except to the extent expressly set forth in the Warrant Agency Agreement.

Section 5. Registration Statement. Following the Issuance Date, the Company is obligated to maintain an effective registration statement on Form S-1 (or other appropriate form) with the Commission covering the issuance of the Preferred Warrant Shares and shares of Common Stock issuable upon conversion of Preferred Warrant Shares until such time as no Warrants remain outstanding, unless there is available an exemption from, or a transaction not subject to, the registration requirements of the Securities Act that covers the issuance of Preferred Warrant Shares and shares of Common Stock issuable upon conversion of Preferred Warrant Shares.

Section 6. Miscellaneous.

a) No Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.

b) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company and the Warrant Agent of an affidavit of loss reasonably satisfactory to the Company and the Warrant Agent evidencing the loss, theft, destruction or mutilation of this Warrant or any share certificate relating to the Preferred Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it and the Warrant Agent, and upon surrender and cancellation of such Warrant or share certificate, if mutilated, the Company will make and deliver a new Warrant or share certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or share certificate.

c) 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 Trading Day, then, such action may be taken or such right may be exercised on the next succeeding Trading Day.

d) Authorized Shares. The Company covenants that, during the period the Warrant is outstanding, it will reserve a sufficient number of shares of authorized and unissued Series J Preferred Stock to provide for the issuance of securities upon the exercise of any subscription rights under this Warrant plus all dividends to be paid on any shares of Series J Preferred Stock outstanding. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Preferred Warrant Shares upon the exercise of the subscription rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such securities may be issued as provided herein without violation of any applicable law or regulation, or

10

of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Preferred Warrant Shares which may be issued upon the exercise of the subscription rights represented by this Warrant will, upon exercise of the subscription rights represented by this Warrant and payment of the Exercise Price for such Preferred Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue). Except and to the extent as waived or consented to by the holders of a majority of the then outstanding Warrants (based on the number of Preferred Warrant Shares underlying such Warrants), the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Preferred Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Preferred Warrant Shares upon the exercise of this Warrant, and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant. Before taking any action which would result in an adjustment in the number of Preferred Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

e) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof.

f) Jurisdiction. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Warrant (whether brought against a party hereto or their respective affiliates, directors, officers, stockholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Warrant. As between a Holder and the Company, (i) each party irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Warrant and agrees that such service shall constitute good and sufficient service of process and notice thereof, (nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law), and (ii) if either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. Notwithstanding the foregoing, nothing in this paragraph shall limit or restrict the federal district court in which a Holder may bring a claim under the federal securities laws.

11

g) Restrictions. The Holder acknowledges that the Preferred Warrant Shares issuable upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

h) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies.

n) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.
