In the event the Company proposes to undertake an issuance of New Securities during such period, it shall give the Purchaser written notice of its intention, describing the type of New Securities, their price, the number of New Securities to be offered, and the general terms upon which the Company proposes to issue the same. The Purchaser shall have ten (10) calendar days after any such notice is delivered to agree to purchase at the same price (which shall be the public purchase price, if applicable) and upon the same terms, including closing date, such New Securities in an amount up to the Purchaser’s pro rata share of such New Securities.

(b) Right of First Refusal/Negotiation. At any time after the date of this Agreement, in the event the Company proposes to undertake an issuance of New Securities, it

- 11 -

shall first give the Purchaser written notice of its intention, describing the type of New Securities, their proposed price, the number of New Securities to be offered, and the general terms upon which the Company proposes to issue the same. The Purchaser shall have the right to purchase or not purchase such New Securities on the proposed terms (the “Right of First Refusal”), and if it chooses not to purchase the New Securities on the proposed terms, it shall have the right to negotiate with Company alternative terms on which to purchase all of such New Securities (the “Right of First Negotiation”). The Purchaser shall have ten (10) calendar days after notice by the Company is delivered to either purchase the New Securities in accordance with the Company’s proposed terms pursuant to its Right of First Refusal or to negotiate with the Company alternative terms to purchase all such New Securities pursuant to its Right of First Negotiation. If the Purchaser timely notifies the Company of its desire to exercise its Right of First Negotiation, then the parties shall negotiate exclusively and in good faith with each other to finalize terms and definitive documentation, for a period of up to twenty (20) days. If the Parties fail to finalize terms and execute and deliver definitive documentation in such twenty (20) day period, the Company shall have ninety (90) days thereafter to sell or enter into an agreement to sell New Securities, at a price and upon terms, economic and otherwise, which are no more favorable to the purchasers than those offered by the Purchaser. In the event the Purchaser elects not to purchase the New Securities pursuant to its Right of First Refusal and not to exercise its Right of First Negotiation, the Company shall have ninety (90) days thereafter to sell or enter into an agreement to sell New Securities, at a price and upon terms no more favorable to the purchasers thereof than specified in the written notice delivered to the Purchaser pursuant to this Section 6(b). In the event the Company has not sold such New Securities or entered into an agreement to sell such New Securities within such ninety (90) day periods, the Company shall not thereafter issue or sell any New Securities without first again complying with this Section 6(b). Notwithstanding, anything contained herein to the contrary, in the event the Purchaser does not exercise the Right of First Refusal or exercises the Right of First Negotiation but fails to reach an agreement with the Company with respect to the purchase of such New Securities, the Purchaser shall have the right to purchase up to its pro rata share of any such New Securities sold in accordance with Section 6(a) above.

(c) Pro Rata Share. For purposes of this Section 6, the Purchaser’s pro rata share is equal to the ratio of (A) the number of shares of Common Stock owned by the Purchaser (including any affiliate thereof) assuming full conversion or exercise of any outstanding convertible securities, rights, options and warrants held by the Purchaser (or any affiliate thereof) into Common Stock to (B) the total number of shares of Common Stock outstanding (assuming full conversion or exercise of any outstanding convertible securities, rights, options and warrants held by the Purchaser (or any affiliate thereof) into Common Stock).

The Purchaser is aware of Rule 144 under the Securities Act and the restrictions imposed thereby and further understands and agrees that so long as the Purchaser beneficially owns 10% or more of the Company’s then outstanding securities or has a Purchaser Designee serving on the Board, the Company will deem the Purchaser to be an “affiliate” as defined in Rule 144(a)(1) and any transfers of the Underlying Shares by the Purchaser shall be subject to the limitations applicable to affiliates set forth in the Securities Act and the rules promulgated thereunder, including without limitation Rule 144.

(c) Legends. The certificate(s) evidencing the Preferred Stock and the Underlying Shares shall bear legends in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON THE TRANSFER THEREOF PURSUANT TO THE TERMS OF A SECURITIES PURCHASE AGREEMENT BETWEEN THE HOLDER AND THE COMPANY AND SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED OR HYPOTHECATED UNTIL SUCH RESTRICTIONS HAVE LAPSED OR HAVE BEEN WAIVED BY THE WRITTEN CONSENT OF THE COMPANY. THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED EXCEPT (A) IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S OF THE SECURITIES ACT, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR (C) PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.”

(d) Agreement to be Bound. Subject to the other restrictions on transfer set forth or referenced in this Agreement (including those set forth in Section 15(h)), the Purchaser may assign all of its rights and obligations hereunder with respect to the Preferred Stock and the

- 24 -

Underlying Shares, provided that the transferee has agreed in writing to be bound by the applicable provisions of this Agreement.

(e) Security Ownership. The Purchaser is aware that the Company is a party to a Shareholder Rights Agreement, dated as of May 31, 2001, between the Company and American Stock Transfer and Trust Company (the “Rights Agreement”), which provides that in the event the Purchaser at any time beneficially owns 15% or more of the Company’s then outstanding capital stock, the Purchaser may be deemed an “Acquiring Person” as defined in the Rights Agreement. The Purchaser understands that, in connection with the Purchaser’s acquisition of the Securities and with respect to the Purchaser’s equity position in the Company, the Company has exempted the Purchaser from being deemed an Acquiring Person as a result of such acquisition or any subsequent transaction so long as the Purchaser acquires its beneficial ownership of shares of capital stock of the Company in a transaction whereby the Purchaser is acquiring such beneficial ownership directly from the Company. Notwithstanding the foregoing, the Purchaser will also not be deemed an Acquiring Person if the percentage of outstanding capital stock owned by the Purchaser increases solely due to the repurchase by the Company of shares of its outstanding capital stock.

11. GUARANTEES AND OTHER OBLIGATIONS AND COVENANTS OF THE COMPANY

(a) Financial Information. From the date of this Agreement, for so long as any portion of the Convertible Notes or Preferred Stock is outstanding or the Purchaser’s ownership of Common Stock of the Company is at least twenty percent (20%) on an as-converted basis, the Company shall provide the Purchaser (i) as soon as practicable after the end of each month, and in any event within thirty (30) days thereafter, unaudited monthly income, balance sheet and cash flow statements and a monthly cash flow budget, (ii) as soon as practicable after the end of each quarter, and in any event within forty-five (45) days thereafter, a consolidated balance sheet of the Company and its subsidiaries as of the end of each such period, consolidated statements of income, consolidated statements of changes in financial condition, a consolidated statement of cash flow of the Company and its subsidiaries and a statement of stockholders’ equity for such period and for the current fiscal year to date, (iii) as soon as practicable, but in any event forty-five (45) days prior to the end of each fiscal year, a projected operating budget and business plan for the next fiscal year, prepared on a monthly basis, including balance sheets and sources and applications of funds statements for such months and, as soon as prepared, any other budgets or revised budgets prepared by the Company, (iv) as soon as practicable after the end of each month, and in any event within ten (10) days thereafter, a twelve (12) month rolling cash projection and a detailed report of payables overdue for thirty (30), sixty (60) and more than ninety (90) days, and (v) such other financial reports that may be reasonably requested by the Purchaser.

(b) Trade Debt. At no time during the period commencing 30 days after the First Closing and for so long as any portion of the Convertible Notes or Preferred Stock is outstanding shall the Company’s past due and unpaid obligations to third parties in respect of goods or services furnished by such third parties to the Company exceed $5,000,000 in the aggregate.

- 25 -

(c) Reservation of Shares. The Company shall at all times reserve a sufficient number of shares of unreserved, authorized and unissued shares of Common Stock to provide for issuance of all of the Underlying Shares issuable upon conversion of the Preferred Stock.

(d) Right of First Negotiation on Partnership/Licensing Opportunities. The Company hereby covenants and agrees that in the event that after the date of this agreement the Company decides to grant a license, sublicense or similar rights to a third party or to enter into a partnership, collaboration or other arrangement to participate in, or lead, the effort to develop or commercialize any Invention or therapeutic product developed by the Company (including the Company’s interest in any Joint Inventions) pursuant to the terms of the Amended and Restated Joint Development and Commercialization Agreement entered into by the Company, the Purchaser and the other parties named therein as of June 30, 2008 (the “JDA”), the Company shall give written notice of such decision to the Purchaser, which notice shall include a detailed description of the terms and conditions with respect to such proposed license or other arrangement. Upon receipt of such notice, the Purchaser shall have a period of thirty (30) days to indicate by written notice to the Company that it desires to exercise a right of first negotiation with respect to such proposed license, sublicense or other arrangement. If the Purchaser timely notifies the Company of its desire to exercise its right of first negotiation, then the parties shall negotiate exclusively and in good faith with each other to finalize terms and definitive documentation, for a period of up to sixty (60) days. If the Parties fail to finalize terms and execute and deliver definitive documentation in such sixty (60) day period, the Company shall be entitled to enter into the proposed license, sublicense or other arrangement with the third party, provided however, that such license, sublicense or arrangement must not be on terms, economic and otherwise, which are more favorable to such third party than those offered by the Purchaser.

(e) Guarantees. Effective upon the date of this Agreement:

(i) The Company shall be deemed to have granted to the Purchaser an exclusive (even as to the Company), fully-paid, royalty-free, right and license or sublicense, as the case may be, under all GTC Technology and the Company’s interest in Joint Inventions and Joint Patent Rights to Develop, make and have made Products in the Co-Exclusive Territory.

(ii) The Purchaser shall be deemed to have been granted the exclusive (even as to the Company) right to Commercialize Products in each country and region of the Co-Exclusive Territory.

(iii) The Company shall be deemed to have granted to the Purchaser an exclusive (even as to the Company), fully-paid, royalty-free, right and license or sublicense, as the case may be, under all GTC Technology and the Company’s interest in Joint Inventions and Joint Patent Rights to develop, make and have made any transgenic compound Controlled (as defined in the JDA) by the Company that is biosimilar to anti-CD20/Rituximab and anti-TNFa/Etanercept/Infliximab.

All capitalized terms not otherwise defined in this Section 11 shall have the meaning ascribed to them in the JDA. The rights, licenses and sublicenses described in Sections

- 26 -

11(e)(i), (ii) and (iii) above shall be terminated if there has been no Event of Default (as defined in each of the respective Convertible Notes) and the Convertible Notes are paid in full or converted in full on or prior to the respective Maturity Date (as defined in each of the respective Convertible Notes). If an Event of Default under either of the Convertible Notes shall occur or the Convertible Notes are not paid in full or converted in full on or prior to the respective Maturity Date, the rights, licenses and sublicenses described in Sections 11(e)(i), (ii) and (iii) above shall automatically become perpetual and non-terminable. The Parties agree to take such actions as may be necessary to prepare and execute an amendment to the JDA to reflect the rights of the Purchaser set forth in Section 11(e)(i) and (ii) above and such other documents and agreements as may be necessary to reflect the rights of the Purchaser set forth in this Section 11(e).

12. PUBLIC STATEMENTS

The Company agrees to disclose on a Current Report on Form 8-K the existence of this Agreement and the transactions contemplated by this Agreement and the material terms, thereof, including pricing, within four (4) business days after the date hereof. The Purchaser shall not issue any press release, or otherwise make any such public statement regarding this Agreement or the transactions contemplated by this Agreement (except for required SEC filings) without the prior written consent of the Company.

13. REGISTRATION RIGHTS

(a) Registration Procedures and Expenses. Except during a Suspension (as defined below), the Company will, upon receipt of written request of the Purchaser and subject to receipt of necessary information from the Purchaser:

(i) as soon as practicable, but in any event no later than 4:00 p.m. Eastern Time on the 30th day after the receipt of such written request from the Purchaser, prepare and file with the SEC a registration statement on Form S-3 or other applicable form available to the Company, including Form S-1 (the “Initial Registration Statement”) covering the resale of all of the Underlying Shares of the Purchaser, provided that the Purchaser has complied with Section 13(e), below together with any shares of capital stock issued or issuable, from time to time, upon any reclassification, share combination, share subdivision, stock split, share dividend or similar transaction or event or otherwise as a distribution on, in exchange for or with respect to any of the foregoing, in each case held at the relevant time by a Purchaser (the “Registrable Securities”); provided, however, that in the event that the SEC specifically prohibits the Initial Registration Statement from including all Registrable Securities of the Purchaser (“SEC Guidance”) (provided that the Company shall advocate with the SEC for the registration of all or the maximum number of the Registrable Securities permitted by SEC Guidance), then the Company will not be in breach of this provision by following such SEC Guidance, and the Company will file such additional Registration Statements (the “Subsequent Registration Statements,” together with the Initial Registration Statement, the “Registration Statements”) at the earliest practicable date on which the Company is permitted by SEC Guidance to file such additional Registration Statements related to the Registrable Securities (the “Subsequent Filing Dates”). If the context so requires, Underlying Shares of the Purchaser will not be considered Registrable Securities for the purposes of a certain

- 27 -

determination of Registrable Securities hereunder if, at that time of such determination, they can be sold pursuant to Rule 144 without volume or manner of sales limitations or have been sold under an effective Registration Statement.

(ii) cause (A) the Initial Registration Statement, as may be amended from time to time, to become effective under the Securities Act as soon as practicable after the Initial Registration Statement is filed by the Company, but in any event no later than 4:00 p.m. Eastern Time on the 120th day after and (B) any Subsequent Registration Statements, as may be amended from time to time, which may be required to be filed hereunder pursuant to Section 13(a)(i) to become effective under the Securities Act as soon as practicable but in any event no later than 4:00 p.m. Eastern Time on the 120th day after such Subsequent Filing Date (each, its “Required Effective Date”);

(iii) cause any prospectus used in connection with any Registration Statement (a “Prospectus”) to be filed with the SEC pursuant to Rule 424(b) under the Securities Act as soon as practicable but in any event no later than two Trading Days following the date such Registration Statement is declared effective by the SEC;

(iv) promptly prepare and file with the SEC such amendments and supplements to the Registration Statements and any Prospectus used in connection therewith (A) as may be necessary to keep such Registration Statements continuously effective until the earlier of (1) such time as all Registrable Securities have been sold pursuant to such Registration Statements, or (2) the date on which all of the Underlying Shares may be resold by the Purchaser without registration pursuant to Rule 144 without volume or manner of sale limitations and (B) as may be reasonably requested by the Purchaser in order to incorporate information concerning the Purchaser or the Purchaser’s intended method of distribution;

(v) so long as any Registration Statement is effective covering the resale of Registrable Securities owned by the Purchaser, furnish to the Purchaser with respect to the Registrable Securities registered under such Registration Statement (and to each underwriter, if any, of such Registrable Securities) such reasonable number of copies of Prospectuses and such other documents as the Purchaser may reasonably request in order to facilitate the public sale or other disposition of all or any of the Registrable Securities by the Purchaser;

(vi) use commercially reasonable efforts to file documents required of the Company for blue sky clearance in any states specified in writing by the Purchaser; provided, however, that the Company shall not be required to qualify to do business generally in any jurisdiction in which the Company is not now so qualified;

(vii) bear all expenses in connection with the procedures in paragraphs (i) through (vi) of this Section 13(a) and the registration of the Registrable Securities pursuant to the Registration Statements, other than fees and expenses, if any, of counsel (except as provided by Section 15(j) below) or other advisers to the Purchaser or underwriting discounts, brokerage fees and commissions incurred by the Purchaser, if any, in connection with an underwritten offering of the Registrable Securities;

- 28 -

(viii) use reasonable best efforts to prevent the issuance of any stop order or other order suspending the effectiveness of the Registration Statements and, if such an order is issued, to obtain the withdrawal thereof at the earliest possible time and to notify the Purchaser of the issuance of such order and the resolution thereof;

(ix) furnish to the Purchaser as soon as practicable after the date that any Registration Statement becomes effective, a letter, dated such date, of outside counsel representing the Company addressed to the Purchaser, confirming the effectiveness of such Registration Statement and, to the knowledge of such counsel, the absence of any stop order;

(x) provide to the Purchaser and its representatives, if requested, the opportunity to conduct a reasonable inquiry of the Company’s financial and other records during normal business hours and make available its officers, directors and employees for questions regarding information which the Purchaser may reasonably request in order to fulfill any due diligence obligation on its part; provided that in the case of this clause (x), the Company shall not be required to provide, and shall not provide, the Purchaser with material, non-public information unless the Purchaser agrees to receive such information and enters into an agreement to keep such material, nonpublic information confidential and refrain from trading in any Company security for so long as such information remains material, nonpublic information; and

(xi) not less than three Trading Days prior to the filing of a Registration Statement and not less than two Trading Days prior to the filing of any related Prospectus or any amendment or supplement thereto (including any document that would be incorporated or deemed to be incorporated therein by reference) or, in the case of comments made by the staff of the SEC and the Company’s responses thereto, within a reasonable period of time following the receipt thereof by the Company, furnish to the Purchaser copies of all such documents proposed to be filed or copies of such correspondence from and to the SEC relating to such Registration Statement, as the case may be, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review of the Purchaser. The Company shall reflect in each such document when so filed with the SEC such comments relating to the Purchaser and its plan of distribution of Registrable Securities as the Purchaser may reasonably propose; provided, however, that such comments from the Purchaser must be received by the Company no later than one Trading Day prior to the filing of such document with the SEC. Notwithstanding any other provision of this Agreement, the Company will have no obligation to deliver or make available to the Purchaser any Registration Statement or Prospectus containing any material, nonpublic information unless the Purchaser specifically consents in advance in writing to receive such material, nonpublic information and the Purchaser has executed an agreement to keep such material, nonpublic information confidential and refrain from trading in any Company security for so long as such information remains material, nonpublic information.

(b) Except during a Suspension (as defined below), (i) each document filed or to be filed with the SEC pursuant to the Exchange Act and incorporated by reference in any Registration Statement complied or will comply when so filed in all material respects with the Exchange Act, (ii) each part of each Registration Statement, when such part shall become effective, will not contain, and each such part, as amended or supplemented, if applicable, will

- 29 -

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, (iii) each Registration Statement 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, (iv) each Registration Statement and Prospectus, as may be amended or supplemented, will comply in all material respects with the Securities Act, and (v) each Prospectus, as may be amended or supplemented, will not, at the time of each sale of the Underlying Shares by the Purchaser, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that the representations and warranties set forth in this paragraph will not apply to statements or omissions in any Registration Statement or Prospectus based upon information relating to the Purchaser furnished to the Company in writing by the Purchaser expressly for use therein.

(c) The Company shall be permitted after the Initial Registration Statement’s Required Effective Date, to suspend for one or more periods (each such period, a “Suspension”) the actions required under Sections 13(a)(i) through (vi) and the use of a Prospectus forming a part of a Registration Statement to the extent that the Board of Directors of the Company concludes in good faith and based on the advice of counsel that the disclosure of additional information in the Prospectus is necessary, whether through an amendment or supplement to such Registration Statement, the filing of an appropriate report with the SEC pursuant to the Exchange Act or otherwise. The Company agrees to file such amendment, supplement or report or otherwise disclose such additional information as soon as practicable following such notice of such Suspension. Notwithstanding the foregoing, the Company agrees that no Suspension shall be for a period of longer than 60 days and no Suspension or Suspensions shall be for an aggregate in any 365-day period of longer than 90 days.

(d) With a view to making available to the Purchaser the benefits of Rule 144 (or its successor rule) and any other rule or regulation of the SEC that may at any time permit the Purchaser to sell Registrable Securities to the public without registration, the Company covenants and agrees to: (A) make and keep public information available, as those terms are understood and defined in Rule 144, until the earlier of (1) one year after such date as all of the Purchasers’ Registrable Securities may be resold without volume or manner of sale limitations pursuant to Rule 144(b) or any other rule of similar effect or (2) such date as all of the Purchasers’ Registrable Securities shall have been resold; (B) file with the SEC in a timely manner all reports and other documents required of the Company under the Exchange Act; and (C) furnish to the Purchaser upon request, as long as the Purchaser owns any Registrable Securities, (1) a written statement by the Company that it has complied with the reporting requirements of the Exchange Act, (2) a copy of the Company’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, except to the extent that such documents are available from the SEC on its EDGAR website, and (3) such other information as may be reasonably requested in order to avail the Purchaser of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration.

(e) It shall be a condition to the Company’s obligations to take any action under this Agreement with respect to the registration of the Purchaser’s Registrable Securities that the Purchaser shall promptly furnish to the Company, upon request, such reasonable and

- 30 -

customary information regarding itself, the Purchaser’s Registrable Securities, and the intended method of disposition of such Registrable Securities. In connection therewith, the Purchaser shall be required to represent to the Company that all such information which is given is both complete and accurate in all material respects when made.

14. INDEMNIFICATION AND CONTRIBUTION

(a) For purposes of this Section 14 only:

(i) the term “Purchaser” shall include the Purchaser and any affiliate (as such term is defined pursuant to Rule 12b-2 promulgated under the Exchange Act) of such Purchaser;

(ii) the term “Prospectus” shall mean the prospectus and any amendment or supplement thereto in the form first filed with the SEC pursuant to Rule 424(b) promulgated under the Securities Act or, if no Rule 424(b) filing is required, filed as part of the Registration Statement at the time of effectiveness, as supplemented or amended from time to time; and

(iii) the term “Registration Statement” shall include any final prospectus, exhibit, supplement or amendment included in or relating to a Registration Statement.

(b) The Company agrees to indemnify and hold harmless the Purchaser, each of its partners and each person, if any, who controls the Purchaser within the meaning of the Securities Act against any losses, claims, damages, liabilities or expenses, joint or several, to which the Purchaser may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed), insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in a Registration Statement or Prospectus, 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, in light of the circumstances in which they were made, not misleading, and will reimburse the Purchaser, each of its partners and each person, if any, who controls the Purchaser within the meaning of the Securities Act for any legal and other expenses as such expenses are reasonably incurred by the Purchaser, any of its partners or any person, if any, who controls the Purchaser within the meaning of the Securities Act in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable to the Purchaser in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in a Registration Statement or Prospectus in reliance upon (and prior to the furnishing by the Purchaser of corrective information to the Company) and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein or (ii) any failure by the Purchaser to comply with the covenant contained in Section 10(a) above respecting the sale of the Underlying Shares during a Suspension unless

- 31 -

such failure by the Purchaser results from the Company’s failure to provide written notice of a Suspension to the Purchaser.

(c) The Purchaser shall indemnify and hold harmless the Company, each of its directors, each of its officers who signed a Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act, against any losses, claims, damages, liabilities or expenses to which the Company, each of its directors, each of its officers who signed a Registration Statement or controlling person may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Purchaser) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon any (i) any failure by the Purchaser to comply with the covenant contained in Section 10(a) above respecting the sale of the Underlying Shares during a Suspension unless such failure by the Purchaser results from the Company’s failure to provide written notice of a Suspension to the Purchaser or (ii) untrue statement or alleged untrue statement of any material fact contained in a Registration Statement or the Prospectus, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in a Registration Statement or Prospectus in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein, and will reimburse the Company, each of its directors, each of its officers who signed a Registration Statement or controlling persons for any legal and other expense reasonably incurred, as such expenses are reasonably incurred by the Company, each of its directors, each of its officers who signed a Registration Statement or controlling persons in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action.

(d) Promptly after receipt by an indemnified party under this Section 14 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 14, promptly notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party hereunder or otherwise to the extent it is not prejudiced as a result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be a conflict between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in

- 32 -

the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 14 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. No indemnifying party, in the defense of any claim covered by this Section 14, shall, except with the prior written consent of the indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release of the indemnified party and the indemnifying party from all liability in respect to such claim. An indemnified party shall not consent to entry of any judgment or enter into any settlement without the prior written consent of the indemnifying party.

(e) If the indemnification provided for in this Section 14 is unavailable to or insufficient to hold harmless an indemnified party under subsection (b) or (c) above in respect of any losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Purchaser on the other in connection with the statements or omissions or other matters which resulted in such losses, claims, damages, liabilities or expenses (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or the Purchaser on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and the Purchaser agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. No person 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.

(f) Notwithstanding the foregoing or anything to the contrary contained herein, the Purchaser will not be liable for any losses, claims, damages, liabilities or expenses (or actions

- 33 -

in respect thereof) in excess of the net amount received by the Purchaser from the sale of the Underlying Shares.

Section 3. Dividends.

(a) Dividends. Holders shall be entitled to receive, and the Corporation shall pay, cumulative dividends at the rate per share (as a percentage of the initial Stated Value) of 10% per annum, payable semiannually on January 1 and July 1, beginning on January 1, 2010, on each Conversion Date (with respect only to shares of Series E-1 Preferred Stock being converted) and on the Redemption Date (each such date, a “Dividend Payment Date”) (if any Dividend Payment Date is not a Trading Day, the applicable payment shall be due on the next succeeding Trading Day) in cash. Dividends on the Series E-1 Preferred Stock shall be calculated on the basis of a 360-day year, consisting of twelve 30-day periods, shall accrue daily commencing on the Original Issue Date, and shall be deemed to accrue from such Original Issue Date whether or not earned or declared and whether or not there are profits, surplus or other funds of the Corporation legally available for the payment of dividends.

Section 4. Voting Rights.

The Series E-1 Preferred Stock shall have no voting rights, except as required by applicable law. Notwithstanding the preceding sentence, as long as any shares of Series E-1 Preferred Stock are outstanding, the Corporation shall not, whether by merger or otherwise, without the affirmative vote of the Holders of a majority of the then outstanding shares of the Series E-1 Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series E-1 Preferred Stock, (b) authorize or create any class of stock ranking as to dividends, redemption or distribution of assets upon a Liquidation senior to or otherwise pari passu with the Series E-1 Preferred Stock; provided, however, that this clause (b) shall not apply to the authorization or creation of the Series E-2 Preferred Stock, (c) amend its Restated Articles of Organization or other charter documents in any manner that adversely affects any rights of the Holders, (d) increase the number of authorized shares of Series E-1 Preferred Stock, (e) take any actions prohibited by Section 6, 9(f), 11(b) and 11(d) of the Securities Purchase Agreement, or (f) enter into any agreement with respect to any of the foregoing.

A Fundamental Transaction or Change of Control Transaction shall not be deemed a Liquidation. The Corporation shall mail written notice of any such Liquidation, not less than 45 days prior to the payment date stated therein, to each Holder.

Section 6. Conversion and Exchange Rights.

(a) Conversions at Option of Holder. Each share of Series E-1 Preferred Stock shall be convertible, at any time and from time to time 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 E-1 Preferred Stock by the Conversion Price. Holders shall effect conversions by providing the Corporation with the form of conversion notice attached hereto as Annex A (a “Notice of Conversion”). Each Notice of Conversion shall specify the number of shares of Series E-1 Preferred Stock to be converted, the number of shares of Series E-1 Preferred Stock owned

prior to the conversion at issue, the number of shares of Series E-1 Preferred Stock owned subsequent to the conversion at issue, the Make-Whole Payment in respect of the shares of Series E-1 Preferred Stock to be converted, and the date on which such conversion is to be effected, which date may not be prior to the date the applicable Holder delivers by facsimile 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 the date that such Notice of Conversion to the Corporation is deemed delivered hereunder. The calculations and entries set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error. To effect conversions of shares of Series E-1 Preferred Stock, a Holder shall be required to surrender the certificate(s) representing such shares of Series E-1 Preferred Stock to the Corporation. Shares of Series E-1 Preferred Stock converted into Common Stock or redeemed in accordance with the terms hereof shall be canceled and shall not be reissued. Upon any conversion of shares of Series E-1 Preferred Stock with a Conversion Date on or prior to the first anniversary of the Original Issue Date of such shares of Series E-1 Preferred Stock, the Company shall pay or cause to be paid to the Holder converting such shares the Make-Whole Payment, if any, in respect of the shares converted in accordance with Section 11.

(b) Conversion Price. The conversion price for the Series E-1 Preferred Stock shall equal $2.63, subject to adjustment as provided herein (the “Conversion Price”).

(d) Mechanics of Conversion.

i. Delivery of Certificate Upon Conversion. Not later than three Trading Days after each Conversion Date (the “Share Delivery Date”), the Corporation shall deliver, or cause to be delivered, to the converting Holder a certificate or certificates representing the number of shares of Common Stock being acquired upon the conversion of shares of Series E-1 Preferred Stock. If, in the case of any Notice of Conversion, such certificate or certificates are not delivered to or as directed by the applicable Holder by the seventh Trading Day after the Conversion Date, the applicable Holder shall be entitled to elect to rescind such Conversion Notice by written notice to the Corporation at any time on or before its receipt of such certificate or certificates, in which event the Corporation shall promptly return to such Holder any original Series E-1 Preferred Stock certificate delivered to the Corporation and such Holder shall promptly return any Common Stock certificates representing the shares of Series E-1 Preferred Stock tendered for conversion to the Corporation.

ii. Obligation Absolute; Partial Liquidated Damages. The Corporation’s obligation to issue and deliver the Conversion Shares upon conversion of Series E-1 Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by such Holder or any other person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares; provided, however, that such delivery

shall not operate as a waiver by the Corporation of any such action that the Corporation may have against such Holder. In the event a Holder shall elect to convert any or all of the Stated Value of its Series E-1 Preferred Stock, the Corporation may not refuse conversion based on any claim that such Holder or any one associated or affiliated with such Holder has been engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining conversion of all or part of the Series E-1 Preferred Stock of such Holder shall have been sought and obtained. In the absence of such injunction, the Corporation shall issue Conversion Shares upon a properly noticed conversion. If the Corporation fails to deliver to a Holder such certificate or certificates pursuant to Section 6(d)(i) on the second Trading Day after the Share Delivery Date applicable to such conversion, the Corporation shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $10,000 of Stated Value of Series E-1 Preferred Stock being converted, $10 per Trading Day for each Trading Day after such second Trading Day after the Share Delivery Date until such certificates are delivered. Nothing herein shall limit a Holder’s right to pursue actual damages or declare a Triggering Event pursuant to Section 9 for the Corporation’s failure to deliver Conversion Shares within the period specified herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit a Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

iii. Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. If the Corporation fails to deliver to a Holder the applicable certificate or certificates by the second Trading Day following the Share Delivery Date pursuant to Section 6(d)(i), and if after such date such Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm purchases, shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then the Corporation shall (A) pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount by which (x) such Holder’s total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Series E-1 Preferred Stock equal to the number of shares of Series E-1 Preferred Stock submitted for conversion or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6(e)(i). For example, if a Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series E-1 Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay such Holder $1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to such Holder in respect of the Buy-In and, upon request of the Corporation, 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 Corporation’s failure to timely deliver certificates representing shares of Common Stock upon conversion of the shares of Series E-1 Preferred Stock as required pursuant to the terms hereof.

iv. Reservation of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times use reasonable best efforts to reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series E-1 Preferred Stock and payment of dividends on the Series E-1 Preferred Stock, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holders of the Series E-1 Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall (subject to the terms and conditions in the Securities Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 7) upon the conversion of all outstanding shares of Series E-1 Preferred Stock and payment of dividends hereunder. The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable and, if a Registration Statement relating to the Conversion Shares is then effective under the Securities Act, shall be registered for public sale in accordance with such Registration Statement.

v. Fractional Shares. Upon a conversion hereunder, the Corporation shall not be required to issue stock certificates representing fractions of shares of Common Stock, but shall if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the VWAP at such time.

vi. Transfer Taxes. The issuance of certificates for shares of the Common Stock on conversion of this Series E-1 Preferred Stock shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holders of such shares of Series E-1 Preferred Stock so converted and the Corporation shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

Section 7. Certain Adjustments.

(a) Stock Dividends and Stock Splits. If the Corporation, at any time while this Series E-1 Preferred Stock is outstanding: (A) pays a stock dividend or otherwise makes a distribution or distributions 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, this Series E-1 Preferred Stock or the Series E-2 Preferred Stock (so long as a similar dividend is paid on this Series E-1 Preferred Stock)); (B) subdivides outstanding shares of Common Stock into a larger number of shares; (C) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares; or (D) 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 shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b) [RESERVED].

(c) Subsequent Rights Offerings. If the Corporation, at any time while this Series E-1 Preferred Stock is outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to Holders) entitling them to subscribe for or purchase shares of Common Stock at a price per share that is lower than the VWAP on the record date referenced below, then the Conversion Price shall be multiplied by a fraction of which the denominator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming delivery to the Corporation in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such VWAP. Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately after the record date for the determination of shareholders entitled to receive such rights, options or warrants.

(d) Pro Rata Distributions. If the Corporation, at any time while this Series E-1 Preferred Stock is outstanding, distributes to all holders of Common Stock (and not to Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security (other than Common Stock, which shall be subject to Section 7(c)), then in each such case the Conversion Price shall be adjusted by multiplying such Conversion Price in effect immediately prior to the record date fixed for determination of shareholders entitled to receive such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the then fair market value at such record date of the portion of such assets, evidence of indebtedness or rights or warrants so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors of the Corporation in good faith. In either case the adjustments shall be described in a statement delivered to the Holders describing the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

(e) Fundamental Transaction. If, at any time while this Series E-1 Preferred Stock is outstanding, (A) the Corporation effects any merger or consolidation of the Corporation with or into another Person, (B) the Corporation effects any sale of all or substantially all of its assets in one transaction or a series of related transactions, (C) any tender offer or exchange offer

(whether by the Corporation or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (D) the Corporation effects any reclassification 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 (in any such case, a “Fundamental Transaction”), then, upon any subsequent conversion of this Series E-1 Preferred Stock, the Holders 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, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had converted the Series E-1 Preferred Stock immediately prior to such Fundamental Transaction (the “Alternate Consideration”). 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 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 Holders shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Series E-1 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 adopt articles of incorporation or an amendment to its articles of incorporation 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 terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 7(e) and insuring that this Series E-1 Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(f) 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.

(g) Notice to the Holders.

i. Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 7, the Corporation shall promptly mail to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any shareholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property or (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of this Series E-1 Preferred Stock, and shall cause to be delivered to each Holder at its last address as it shall appear upon the stock books of the Corporation, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, 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 Common 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 Common Stock of record shall be entitled to exchange their shares of the Common 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. The Holder is entitled to convert the Stated Value of its Series E-1 Preferred Stock during the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice.

Section 8. Five Year Redemption. On or after the fifth anniversary of the Original Issue Date of any shares Series E-1 Preferred Stock, the Company shall have the right to redeem all, but not less than all, and the Holder of such shares of Series E-1 Preferred Stock, upon written notice to the Corporation, shall have the right to cause the Corporation to redeem all, but not less than all, of such shares of Series E-1 Preferred Stock, for an amount in cash equal to the Five Year Redemption Amount (such redemption, the “Five Year Redemption”). The Corporation covenants and agrees that it will honor all Conversion Notices tendered pursuant to this Section 8. Any notice of redemption given by the Corporation or the Holder (a “Redemption Notice”) shall be in writing and shall specify the date on which such redemption shall take place (the “Redemption Date”), which shall not be less than three (3) Business Days nor more than five (5) Business Days from the date of such Redemption Notice. If any portion of the cash payment for a Five Year Redemption has not been paid by the Corporation on the Redemption Date, interest shall accrue thereon until such amount is paid in full at a rate equal to the lesser of 18% per annum or the maximum rate permitted by applicable law.

Section 9. Redemption Upon Triggering Events.

(a) “Triggering Event” means any one or more of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body):

i. the Corporation shall fail to deliver certificates representing Conversion Shares issuable upon a conversion hereunder that comply with the provisions hereof prior to the fifth Trading Day after such certificates are required to be delivered hereunder, or the Corporation shall provide written notice to any Holder, including by way of public announcement, at any time, of its intention not to comply with requests for conversion of any shares of Series E-1 Preferred Stock in accordance with the terms hereof;

ii. the Corporation shall fail (after written demand from the Holder) to have available a sufficient number of authorized and unreserved shares of Common Stock to issue to such Holder upon a conversion hereunder;

iii. unless specifically addressed elsewhere in this Certificate of Designation as a Triggering Event, the Corporation shall fail to observe or perform any other covenant or agreement contained in the Preferred Transaction Documents, written notice specifying such failure and requiring it to be remedied (and stating that such notice is a “Notice of Default”) shall have been delivered to the Corporation by the Holders of at least 67% of the shares of Series E-1 Preferred Stock then outstanding, and such failure shall not, if subject to the possibility of a cure by the Corporation, have been cured within 30 calendar days after the date on which such written notice was delivered;

iv. the Corporation shall be party to a Change of Control Transaction; or

v. there shall have occurred a Bankruptcy Event.

(b) Rights Upon Triggering Event. Upon the occurrence of a Triggering Event, each Holder shall (in addition to all other rights it may have hereunder or under applicable law) have the right, exercisable at the sole option of such Holder, to require the Corporation to redeem all of the Series E-1 Preferred Stock then held by such Holder for a redemption price equal to the Triggering Redemption Amount; provided, however, that if a Triggering Event arises from the failure to register the re-sale of certain shares of Conversion Shares, the Corporation (i) shall only be so required to redeem those shares of Series E-1 Preferred Stock whose underlying Conversion Shares’ re-sale the Corporation has failed to register, and (ii) shall have 45 calendar days to cure such Triggering Event after delivery of the Notice of Default. The Triggering Redemption Amount shall be due and payable within five Trading Days of the date on which the notice for the payment therefor is provided by a Holder (the “Triggering Redemption Payment Date”). If the Corporation fails to pay in full the Triggering Redemption Amount hereunder on the date such amount is due in accordance with this Section, the Corporation will pay interest thereon at a rate equal to the lesser of 18% per annum or the maximum rate permitted by applicable law, accruing daily from such date until the Triggering Redemption Amount, plus all such interest thereon, is paid in full. For purposes of this Section, a share of Series E-1 Preferred Stock is outstanding until such date as the applicable Holder has been paid the Triggering Redemption Amount in cash.

Section 10. Negative Covenants. So long as any shares of Series E-1 Preferred Stock are outstanding, unless the holders of at least 67% of the then outstanding shares of Series E-1 Preferred Stock shall have otherwise given prior written consent, the Corporation shall not, and

shall not permit any of its subsidiaries (whether or not a Subsidiary on the Original Issue Date) to, directly or indirectly:

(a) amend the Restated Articles of Organization, its bylaws or other charter documents so as to materially and adversely affect any rights of any Holder;

(b) repay, repurchase or offer to repay, repurchase or otherwise acquire any shares of its Common Stock, Common Stock Equivalents or Junior Securities, except for the Conversion Shares to the extent permitted or required under the Preferred Transaction Documents or as otherwise permitted by the Preferred Transaction Documents;

(d) enter into, create, incur, assume, guarantee or suffer to exist any Indebtedness, except as allowed or consented to under the Security Agreement; or

(e) enter into any agreement or understanding with respect to any of the foregoing.

Section 11. Make-Whole Payment. Upon the conversion of any shares of Series E-1 Preferred Stock pursuant to Section 6 hereof and provided that the Conversion Date for such shares occurs on or prior to the first anniversary of the Original Issue Date of such shares, the Corporation shall pay or cause to be paid to the Holder of the Series E-1 Preferred Stock so converted cash with respect to the shares of Series E-1 Preferred Stock so converted in an amount equal to $500 per $1,000 Stated Value of the Series E-1 Preferred Stock, less the amount of any dividends paid in respect of the Series E-1 Preferred Stock before the relevant Conversion Date (the “Make-Whole Payment”). The Company shall pay or cause the Make-Whole Payment to be paid within five (5) Business Days of the applicable Conversion Date. If the Make-Whole Payment is not made when due, the Make-Whole Payment shall accrue interest at the rate of 18% per annum or the lesser rate permitted by applicable law (such interest shall accrue daily from the due date through and including the date of payment).

Section 12. Miscellaneous.

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 sent by a nationally recognized overnight courier service, addressed to the Corporation, at 175 Crossing Boulevard, Framingham, Massachusetts 01702, Attention: Chief Financial Officer, Facsimile: (508) ###-###-#### with a copy (which shall not constitute notice) to Edwards Angell Palmer & Dodge LLP, 111 Huntington Avenue, Boston, Massachusetts, Attention: Nathaniel S.

A Fundamental Transaction or Change of Control Transaction shall not be deemed a Liquidation. The Corporation shall mail written notice of any such Liquidation, not less than 45 days prior to the payment date stated therein, to each Holder.

Section 6. Conversion and Exchange Rights.

(a) Conversions at Option of Holder. Each share of Series E-2 Preferred Stock shall be convertible, at any time and from time to time 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 E-2 Preferred Stock by the Conversion Price. Holders shall effect conversions by providing the Corporation with the form of conversion notice attached hereto as Annex A (a “Notice of Conversion”). Each Notice of Conversion shall specify the number of shares of Series E-2 Preferred Stock to be converted, the number of shares of Series E-2 Preferred Stock owned prior to the conversion at issue, the number of shares of Series E-2 Preferred Stock owned subsequent to the conversion at issue, the Make-Whole Payment in respect of the shares of Series E-2 Preferred Stock to be converted, and the date on which such conversion is to be effected, which date may not be prior to the date the applicable Holder delivers by facsimile 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 the date that such Notice of Conversion to the Corporation is deemed delivered hereunder. The calculations and entries set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error. To effect conversions of shares of Series E-2 Preferred Stock, a Holder shall be required to surrender the certificate(s) representing such shares of Series E-2 Preferred Stock to the Corporation. Shares of Series E-2 Preferred Stock converted into Common Stock or redeemed in accordance with the terms hereof shall be canceled and shall not be reissued. Upon any conversion of shares of Series E-2 Preferred Stock with a Conversion Date on or prior to the first anniversary of the Original Issue Date of such shares of Series E-2 Preferred Stock, the Company shall pay or cause to be paid to the Holder converting such shares the Make-Whole Payment, if any, in respect of the shares converted in accordance with Section 11.

(b) Conversion Price. The conversion price for the Series E-2 Preferred Stock shall equal the lesser of (i) $2.63 or (ii) the VWAP of the Common Stock on the Shareholder Approval Date, subject to adjustment as provided herein (the “Conversion Price”).

(d) Mechanics of Conversion.

i. Delivery of Certificate Upon Conversion. Not later than three Trading Days after each Conversion Date (the “Share Delivery Date”), the Corporation shall deliver, or cause to be delivered, to the converting Holder a certificate or certificates representing the number of shares of Common Stock being acquired upon the conversion of shares of Series E-2 Preferred Stock. If, in the case of any Notice of Conversion, such certificate or certificates are not delivered to or as directed by the applicable Holder by the seventh Trading Day after the Conversion Date, the applicable Holder shall be entitled to elect to rescind such Conversion Notice by written notice to the Corporation at any time on or before its receipt of such certificate or certificates, in which event the Corporation shall promptly return to such Holder any original Series E-2 Preferred Stock certificate delivered to the Corporation and such Holder shall promptly return any Common Stock certificates representing the shares of Series E-2 Preferred Stock tendered for conversion to the Corporation.

ii. Obligation Absolute; Partial Liquidated Damages. The Corporation’s obligation to issue and deliver the Conversion Shares upon conversion of Series E-2 Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or

any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by such Holder or any other person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares; provided, however, that such delivery shall not operate as a waiver by the Corporation of any such action that the Corporation may have against such Holder. In the event a Holder shall elect to convert any or all of the Stated Value of its Series E-2 Preferred Stock, the Corporation may not refuse conversion based on any claim that such Holder or any one associated or affiliated with such Holder has been engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining conversion of all or part of the Series E-2 Preferred Stock of such Holder shall have been sought and obtained. In the absence of such injunction, the Corporation shall issue Conversion Shares upon a properly noticed conversion. If the Corporation fails to deliver to a Holder such certificate or certificates pursuant to Section 6(d)(i) on the second Trading Day after the Share Delivery Date applicable to such conversion, the Corporation shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $10,000 of Stated Value of Series E-2 Preferred Stock being converted, $10 per Trading Day for each Trading Day after such second Trading Day after the Share Delivery Date until such certificates are delivered. Nothing herein shall limit a Holder’s right to pursue actual damages or declare a Triggering Event pursuant to Section 9 for the Corporation’s failure to deliver Conversion Shares within the period specified herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit a Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

iii. Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. If the Corporation fails to deliver to a Holder the applicable certificate or certificates by the second Trading Day following the Share Delivery Date pursuant to Section 6(d)(i), and if after such date such Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm purchases, shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then the Corporation shall (A) pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount by which (x) such Holder’s total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Series E-2 Preferred Stock equal to the number of shares of Series E-2 Preferred Stock submitted for conversion or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6(e)(i). For example, if a Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series E-2 Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of

the immediately preceding sentence, the Corporation shall be required to pay such Holder $1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to such Holder in respect of the Buy-In and, upon request of the Corporation, 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 Corporation’s failure to timely deliver certificates representing shares of Common Stock upon conversion of the shares of Series E-2 Preferred Stock as required pursuant to the terms hereof.

iv. Reservation of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times use reasonable best efforts to reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series E-2 Preferred Stock and payment of dividends on the Series E-2 Preferred Stock, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holders of the Series E-2 Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall (subject to the terms and conditions in the Securities Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 7) upon the conversion of all outstanding shares of Series E-2 Preferred Stock and payment of dividends hereunder. The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable and, if a Registration Statement relating to the Conversion Shares is then effective under the Securities Act, shall be registered for public sale in accordance with such Registration Statement.

vi. Transfer Taxes. The issuance of certificates for shares of the Common Stock on conversion of this Series E-2 Preferred Stock shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holders of such shares of Series E-2 Preferred Stock so converted and the Corporation shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

Section 7. Certain Adjustments.

(a) Stock Dividends and Stock Splits. If the Corporation, at any time while this Series E-2 Preferred Stock is outstanding: (A) pays a stock dividend or otherwise makes a distribution or distributions 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, this

Series E-2 Preferred Stock or the Series E-1 Preferred Stock (so long as a similar dividend is paid on this Series E-2 Preferred Stock)); (B) subdivides outstanding shares of Common Stock into a larger number of shares; (C) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares; or (D) 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 shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b) [RESERVED].

(c) Subsequent Rights Offerings. If the Corporation, at any time while this Series E-2 Preferred Stock is outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to Holders) entitling them to subscribe for or purchase shares of Common Stock at a price per share that is lower than the VWAP on the record date referenced below, then the Conversion Price shall be multiplied by a fraction of which the denominator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming delivery to the Corporation in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such VWAP. Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately after the record date for the determination of shareholders entitled to receive such rights, options or warrants.

(d) Pro Rata Distributions. If the Corporation, at any time while this Series E-2 Preferred Stock is outstanding, distributes to all holders of Common Stock (and not to Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security (other than Common Stock, which shall be subject to Section 7(c)), then in each such case the Conversion Price shall be adjusted by multiplying such Conversion Price in effect immediately prior to the record date fixed for determination of shareholders entitled to receive such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the then fair market value at such record date of the portion of such assets, evidence of indebtedness or rights or warrants so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors of the Corporation in good faith. In either case the adjustments shall be described in a statement delivered to the Holders describing the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

(e) Fundamental Transaction. If, at any time while this Series E-2 Preferred Stock is outstanding, (A) the Corporation effects any merger or consolidation of the Corporation with or into another Person, (B) the Corporation effects any sale of all or substantially all of its assets in one transaction or a series of related transactions, (C) any tender offer or exchange offer (whether by the Corporation or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (D) the Corporation effects any reclassification 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 (in any such case, a “Fundamental Transaction”), then, upon any subsequent conversion of this Series E-2 Preferred Stock, the Holders 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, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had converted the Series E-2 Preferred Stock immediately prior to such Fundamental Transaction (the “Alternate Consideration”). 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 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 Holders shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Series E-2 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 adopt articles of incorporation or an amendment to its articles of incorporation 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 terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 7(e) and insuring that this Series E-2 Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(g) Notice to the Holders.

ii. Notice to Allow Conversion by Holder. If (A) the Corporation shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Corporation shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Corporation shall authorize the granting to all holders of the Common Stock of 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 shareholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property or (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of this Series E-2 Preferred Stock, and shall cause to be delivered to each Holder at its last address as it shall appear upon the stock books of the Corporation, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, 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 Common 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 Common Stock of record shall be entitled to exchange their shares of the Common 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. The Holder is entitled to convert the Stated Value of its Series E-2 Preferred Stock during the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice.

Section 8. Five Year Redemption. On or after the fifth anniversary of the Original Issue Date of any shares Series E-2 Preferred Stock, the Company shall have the right to redeem all, but not less than all, and the Holder of such shares of Series E-2 Preferred Stock, upon written notice to the Corporation, shall have the right to cause the Corporation to redeem all, but not less than all, of such shares of Series E-2 Preferred Stock, for an amount in cash equal to the Five Year Redemption Amount (such redemption, the “Five Year Redemption”). The Corporation covenants and agrees that it will honor all Conversion Notices tendered pursuant to this Section 8. Any notice of redemption given by the Corporation or the Holder (a “Redemption Notice”) shall be in writing and shall specify the date on which such redemption shall take place (the “Redemption Date”), which shall not be less than three (3) Business Days nor more than five (5) Business Days from the date of such Redemption Notice. If any portion of the cash payment for a Five Year Redemption has not been paid by the Corporation on the Redemption Date, interest shall accrue thereon until such amount is paid in full at a rate equal to the lesser of 18% per annum or the maximum rate permitted by applicable law.

Section 9. Redemption Upon Triggering Events.

(a) “Triggering Event” means any one or more of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or

pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body):

i. the Corporation shall fail to deliver certificates representing Conversion Shares issuable upon a conversion hereunder that comply with the provisions hereof prior to the fifth Trading Day after such certificates are required to be delivered hereunder, or the Corporation shall provide written notice to any Holder, including by way of public announcement, at any time, of its intention not to comply with requests for conversion of any shares of Series E-2 Preferred Stock in accordance with the terms hereof;

iii. unless specifically addressed elsewhere in this Certificate of Designation as a Triggering Event, the Corporation shall fail to observe or perform any other covenant or agreement contained in the Preferred Transaction Documents, written notice specifying such failure and requiring it to be remedied (and stating that such notice is a “Notice of Default”) shall have been delivered to the Corporation by the Holders of at least 67% of the shares of Series E-2 Preferred Stock then outstanding, and such failure shall not, if subject to the possibility of a cure by the Corporation, have been cured within 30 calendar days after the date on which such written notice was delivered;

iv. the Corporation shall be party to a Change of Control Transaction; or

v. there shall have occurred a Bankruptcy Event.

(b) Rights Upon Triggering Event. Upon the occurrence of a Triggering Event, each Holder shall (in addition to all other rights it may have hereunder or under applicable law) have the right, exercisable at the sole option of such Holder, to require the Corporation to redeem all of the Series E-2 Preferred Stock then held by such Holder for a redemption price equal to the Triggering Redemption Amount; provided, however, that if a Triggering Event arises from the failure to register the re-sale of certain shares of Conversion Shares, the Corporation (i) shall only be so required to redeem those shares of Series E-2 Preferred Stock whose underlying Conversion Shares’ re-sale the Corporation has failed to register, and (ii) shall have 45 calendar days to cure such Triggering Event after delivery of the Notice of Default. The Triggering Redemption Amount shall be due and payable within five Trading Days of the date on which the notice for the payment therefor is provided by a Holder (the “Triggering Redemption Payment Date”). If the Corporation fails to pay in full the Triggering Redemption Amount hereunder on the date such amount is due in accordance with this Section, the Corporation will pay interest thereon at a rate equal to the lesser of 18% per annum or the maximum rate permitted by applicable law, accruing daily from such date until the Triggering Redemption Amount, plus all such interest thereon, is paid in full. For purposes of this Section, a share of Series E-2 Preferred Stock is outstanding until such date as the applicable Holder has been paid the Triggering Redemption Amount in cash.

Section 10. Negative Covenants. So long as any shares of Series E-2 Preferred Stock are outstanding, unless the holders of at least 67% of the then outstanding shares of Series E-2 Preferred Stock shall have otherwise given prior written consent, the Corporation shall not, and shall not permit any of its subsidiaries (whether or not a Subsidiary on the Original Issue Date) to, directly or indirectly:

(a) amend the Restated Articles of Organization, its bylaws or other charter documents so as to materially and adversely affect any rights of any Holder;

(d) enter into, create, incur, assume, guarantee or suffer to exist any Indebtedness, except as allowed or consented to under the Security Agreement; or

(e) enter into any agreement or understanding with respect to any of the foregoing.

Section 11. Make-Whole Payment. Upon the conversion of any shares of Series E-2 Preferred Stock pursuant to Section 6 hereof and provided that the Conversion Date for such shares occurs on or prior to the first anniversary of the Original Issue Date of such shares, the Corporation shall pay or cause to be paid to the Holder of the Series E-2 Preferred Stock so converted cash with respect to the shares of Series E-2 Preferred Stock so converted in an amount equal to $500 per $1,000 Stated Value of the Series E-2 Preferred Stock, less the amount of any dividends paid in respect of the Series E-2 Preferred Stock before the relevant Conversion Date (the “Make-Whole Payment”). The Company shall pay or cause the Make-Whole Payment to be paid within five (5) Business Days of the applicable Conversion Date. If the Make-Whole Payment is not made when due, the Make-Whole Payment shall accrue interest at the rate of 18% per annum or the lesser rate permitted by applicable law (such interest shall accrue daily from the due date through and including the date of payment).

(c) Lost or Mutilated Series E-2 Preferred Stock Certificate.
