The Company agrees to indemnify each Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever (whether or not resulting from third-party claims), and hold each of them harmless against, any and all actions, suits, proceedings, investigations, demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Company contained herein, provided that such claim for indemnification relating to a breach of the representations or warranties is made prior to the expiration of such representations or warranties to the extent applicable; and provided, further, that no Purchaser Related Party shall be entitled to recover special, consequential or punitive damages under this Section 6.1 (other than to the extent included in amounts payable to third parties in respect of third-party claims).

Section 6.2 Indemnification by Purchasers. Each Purchaser agrees, severally and not jointly, to indemnify the Company and its respective officers, directors, managers, employees and agents (collectively, “Company Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings, investigations, demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of such Purchaser contained herein, provided that such claim for indemnification relating to a breach of the representations and warranties is made prior to the expiration of such representations and warranties; and provided, further, that no Company Related Party shall be entitled to recover special, consequential or punitive damages; and provided, further, that the liability of a Purchaser shall not be greater in amount than such Purchaser’s Purchase Price.

Section 6.3 Indemnification Procedure. Promptly after any Company Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the

Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the sole cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (a) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (b) if (i) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (ii) the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party. The remedies provided for in this Article VI are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

Section 7.4 No Waiver; Modifications in Writing.

(a) Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

No portion of the rights and obligations of any Purchaser under this Agreement may be transferred by such Purchaser to a non-Affiliate without the written consent of the Company (which consent shall not be unreasonably withheld by the Company).

Section 7.6 Confidentiality.

Section 7.8 Removal of Legend. In connection with a sale of the Purchased Shares by a Purchaser in reliance on Rule 144, the applicable Purchaser or its broker shall deliver to the transfer agent and the Company a seller or broker representation letter, as applicable, providing to the transfer agent and the Company any information the Company or the transfer agent deems reasonably necessary to determine that the sale of the Purchased Shares is made in compliance with Rule 144, including, as may be appropriate, a certification that the Purchaser is not an Affiliate of the Company and regarding the length of time the Purchased Shares have been held. Upon receipt of such representation letter, the Company shall promptly direct its transfer agent to remove the notation of a restrictive legend in such Purchaser’s book-entry account maintained by the transfer agent, including the legend referred to in Section 4.12, and the Company shall bear all costs associated therewith. After a registration statement under the Securities Act permitting the public resale of the Purchased Shares has become effective or any Purchaser or its permitted assigns have held the Purchased Shares for one year, if the book-entry account of such Purchased Shares still bears the notation of the restrictive legend referred to in Section 4.12, the Company agrees, upon request of the Purchaser or permitted assignee, to take all steps reasonably requested by the transfer agent to effect the removal of the legend described in Section 4.12 from the Purchased Shares, and the Company shall bear all costs associated therewith, regardless of whether the request is made in connection with a sale or otherwise, so long as such Purchaser or its permitted assigns provide to the Company any information the Company deems reasonably necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including (if there is no such registration statement) a certification that the holder is not an Affiliate of the Company (and a covenant to inform the Company if it should thereafter become an Affiliate and to consent to the notation of an appropriate restriction) and regarding the length of time the Purchased Shares have been held.

Section 7.9 Entire Agreement. This Agreement, the other Operative Documents and the other agreements and documents referred to herein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or the other Operative Documents with respect to the rights granted by the Company or any of its Affiliates or any Purchaser or any of its Affiliates set forth herein or therein. This Agreement, the other Operative Documents and the other agreements and documents referred to herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter.

Section 7.10 Governing Law. This Agreement, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement), will be construed in accordance with and governed by the laws of the State of New York without regard to principles of conflicts of laws. Any action against any party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of New York, and the parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of New York over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection that they may now or hereafter have to the laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

Section 7.11 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 7.12 Termination.

(a) Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate at any time at or prior to the Closing if a statute, rule, order, decree or regulation shall have been enacted or promulgated, or if any action shall have been taken by any Governmental Authority of competent jurisdiction that permanently restrains, permanently precludes, permanently enjoins or otherwise permanently prohibits the consummation of the transactions contemplated by this Agreement or makes the transactions contemplated by this Agreement illegal.

(b) Notwithstanding anything herein to the contrary, this Agreement may be terminated at any time upon mutual consent of the Company and the Purchasers or by any Purchaser (with respect to the obligations of such Purchaser) or the Company, upon written notice to the other party, if the Closing shall not have occurred on or before the date that is five business days from the date of this Agreement (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 7.12(b) shall not be available to any party whose (i) breach of any provision of this Agreement, (ii) failure to comply with its obligations under this Agreement or (iii) actions not taken in good faith shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to the Outside Date or the failure of a condition in Sections 2.3 or 2.4 to be satisfied at such time.

(c) In the event of the termination of this Agreement as provided in this Section 7.12, (i) this Agreement shall forthwith become null and void and (ii) there shall be no liability on the part of any party hereto, except as set forth in Article VI of this Agreement and except with respect to the requirement to comply with any confidentiality agreement in favor of the Company; provided that nothing herein shall relieve any party from any liability or obligation with respect to any willful breach of this Agreement.

Section 7.13 Other Relationships. Each of the Purchasers acknowledges and agrees that (i) the Placement Agents and certain of their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities, and have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for the Company and its affiliates, for which they received or may in the future receive customary fees and expenses, and (ii) affiliates of each of the Placement Agents act as lenders and agents under the Company’s bank credit facilities, and may directly or indirectly receive their respective shares of any repayment by the Company of its outstanding credit facility from the proceeds of this transaction.

Neither the Placement Agents nor any of their Affiliates or Representatives (1) shall be liable for any improper payment made in accordance with the information provided by the Company; (2) makes any representation or warranty, or has any responsibilities as to the validity, enforceability, accuracy, value or genuineness of any information, certificates or documentation delivered by or on behalf of the Company pursuant to the Operative Documents or in connection with any of the transactions contemplated therein; or (3) shall be liable (x) for any action taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights or powers conferred upon it by the Operative Documents or (y) for anything which any of them may do or refrain from doing in connection with the Operative Documents, except in each case for such party’s own gross negligence or willful misconduct.

The Company agrees that the Placement Agents, their affiliates and Representatives shall be entitled to (1) rely on, and shall be protected in acting upon, any certificate, instrument, notice, letter or any other document or security delivered to any of them by or on behalf of the Company, and (2) be indemnified by the Company for acting as the Placement Agents hereunder pursuant to the indemnification provisions set forth in the applicable letter agreement between the Company and the Placement Agents.

REGISTRATION RIGHTS

Section 2.01 Mandatory Registration.

(a) No later than 15 days following the closing under the Common Stock Subscription Agreement (the “Filing Deadline”), the Company shall prepare and file a (i) prospectus supplement under Rule 424(b) of the Securities Act or (ii) new registration statement under the Securities Act to permit the public resale of Registrable Securities then outstanding from time to time as permitted by Rule 415 of the Securities Act with respect to all of the Registrable Securities

(the “Registration Statement”). The Registration Statement filed pursuant to this Section 2.01(a) shall be on such appropriate registration form of the Commission as shall be selected by the Company so long as it permits the continuous offering of the Registrable Securities pursuant to Rule 415 of the Securities Act or such other rule as is then applicable at the then prevailing market prices. The Company shall use its reasonable best efforts to ensure the Registration Statement is effective on or as soon as practicable after the filing thereof but in any event no later than the earlier of (a) the 75th calendar day following the initial filing date of the Registration Statement if the Commission notifies the Company that it will “review” the Registration Statement and (b) the fifth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such date, the “Effectiveness Deadline”). Any Registration Statement shall provide for the resale pursuant to such method or combination of methods legally available to, and requested by, the Holders of Registrable Securities covered by such Registration Statement. The Company shall use its reasonable best efforts to cause the Registration Statement filed pursuant to this Section 2.01(a) to be effective, supplemented and amended to the extent necessary to ensure that it is available for the resale of Registrable Securities by the Holders until all Registrable Securities covered by such Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). The Registration Statement when effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and will not contain an 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 (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, but in any event within one Business Day of such date, the Company shall provide the Holders with written notice of the effectiveness of the Registration Statement.

(b) Each Holder (other than any initial Purchaser of Common Stock under the Common Stock Subscription Agreement) that provides a completed Notice and Questionnaire to the Company agrees that, if such Holder wishes to sell Registrable Securities pursuant to the Registration Statement and related prospectus, it will do so only in accordance with this Section 2.01(b). Each such Holder wishing to sell Registrable Securities pursuant to the Registration Statement and related prospectus agrees to deliver a Notice and Questionnaire to the Company at least five Business Days prior to any intended distribution of Registrable Securities under the Registration Statement. From and after the date the Registration Statement is declared effective, the Company shall, as promptly as practicable after the date a Notice and Questionnaire is delivered to it, and in any event by the later of (x) five Business Days after such date, (y) ten Business Days after effectiveness or (z) if a Blackout and Delay Event is in effect when, or is put into effect within five Business Days after, the Notice and Questionnaire is delivered, ten Business Days after the expiration of such Blackout and Delay Event:

(i) if required by applicable law, file with the Commission a post-effective amendment to the Registration Statement or prepare and, if required by applicable law, file a prospectus or a supplement to the related prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such Notice and Questionnaire is named as a selling security holder in the Registration Statement

and the related prospectus in such a manner as to permit such Holder to deliver such prospectus to purchasers of Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Registration Statement, use its reasonable best efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable, but in any event by the date that is the earlier of the 75th calendar day following the filing of the post-effective amendment if the Commission notifies the Company that it will “review” the post-effective amendment and (b) the fifth Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the post-effective amendment will not be “reviewed” or will not be subject to further review;

(ii) provide such Holder copies of any documents filed pursuant to Section 2.01(b)(i); and

(iii) notify such Holder as promptly as practicable but in any event within 24 hours after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 2.01(b)(i);

provided that if such Notice and Questionnaire is delivered during a Blackout and Delay Event, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall not be obligated to take the actions set forth in clauses (i), (ii) and (iii) until the expiration of the Blackout and Delay Event in accordance with Section 2.03.

Section 2.02 Failure to Obtain and Maintain Effectiveness; Liquidated Damages.

(a) If (i) the Company has not filed the Registration Statement with the Commission on or prior to the Filing Deadline or the Registration Statement is not effective on or prior to the Effectiveness Deadline (in each case, other than due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to be provided by or on behalf of a Holder to the Company for inclusion in the Registration Statement), (ii) during the Effectiveness Period, the Registration Statement ceases to be effective or the Holders are otherwise not permitted to resell Registrable Securities pursuant to the Registration Statement (other than due to a Blackout and Delay Event or (A) due to the inaccuracy or omission of any information relating to any Holder provided in writing or required to be provided by or on behalf of a Holder to the Company for inclusion in the Registration Statement or (B) for a period of up to 90 days following the filing of a post-effective amendment or in connection with conversion from Form S-1 to Form S-3, or (iii) the Company fails to satisfy the current public information requirement pursuant to Rule 144(c)(1) as a result of which the Holders are unable to sell Registrable Securities without restriction under Rule 144 (any such failure or breach, an “Event” and the date of any Event, an “Event Date”), then each Holder shall be entitled to a payment, as liquidated damages and not as a penalty, in an amount equal to 0.25% of such Holder’s Liquidated Damages Base per 30-day period, which amount shall accrue daily, for the first 30 days following the applicable Event Date, increasing by an additional 0.25% of such Holder’s Liquidated Damages Base for each subsequent 30-day period, up to a maximum of 1.0% of such Holder’s Liquidated Damages Base per 30-day period (i.e. 0.50% for the period of 31-60 days following the applicable Event Date, 0.75% for the period of 61-90 days following the applicable Event Date and 1.0% for each

30-day period thereafter) (the “Liquidated Damages”), subject to the maximum aggregate limitations in Section 2.02(b). Liquidated Damages payable to a Holder shall cease to accrue when the Event is cured or the Holder no longer owns Registrable Securities, whichever is earlier, and shall be prorated in the event Liquidated Damages cease to accrue prior to the end of the applicable 30-day calculation period.

(b) The parties agree that the maximum aggregate Liquidated Damages payable to a Holder shall be 5% of such Holder’s Liquidated Damages Base, regardless of the number of Events that occur, provided that the maximum aggregate Liquidated Damages payable to a Holder shall be 10% of such Holder’s Liquidated Damages Base to the extent the excess over 5% of the Holder’s Liquidated Damages Base is due to an Event or Events under clause (iii) of Section 2.02(a).

(c) Liquidated Damages shall be paid to each Holder in immediately available funds within ten Business Days of the end of each applicable 30-day calculation period following an Event Date, or such shorter period of time if the applicable Event is cured before the end of any 30-day calculation period. Any Liquidated Damages due under this Section 2.02 shall constitute the Holders’ exclusive remedy for such events but shall not affect the right of any Holder to seek injunctive relief.

Section 2.03 Blackout and Delay Events. Notwithstanding anything to the contrary contained herein:

(a) the Company shall not be required to file a Registration Statement (or any amendment thereto) or, if a Registration Statement has been filed but not declared effective by the Commission, request effectiveness of such Registration Statement, for not more than 45 consecutive days or for a total of not more than 90 days in any 365 day period, if (i) the Company determines in good faith that a postponement is in the best interest of the Company and its stockholders generally due to a pending transaction involving the Company (including a pending securities offering by the Company, or any proposed financing, acquisition, merger, tender offer, business combination, corporate reorganization, consolidation or other significant transaction involving the Company), (ii) the Company determines such registration would render the Company unable to comply with applicable securities laws, (iii) the Company determines such registration would require disclosure of material information that the Company has a bona fide business purpose for preserving as confidential, or (iv) audited financial statements as of a date other than the fiscal year end of the Company would be required to be prepared; provided, however, that the Company shall promptly (A) notify each Holder in writing of the commencement of such Blackout and Delay Event, but shall not (without the prior written consent of a Holder) disclose to such Holder any material, non-public information giving rise to such Blackout and Delay Event described in this Section 2.03(a), (B) advise the Holders in writing to cease all sales under the Registration Statement until the end of such Blackout and Delay Event and (c) except in the case of a Blackout and Delay Event described in Section 2.3(a)(i) or (iii), use commercially reasonable efforts to terminate such Blackout and Delay Event as promptly as practicable; and

(b) the Company may, upon written notice to any Selling Holder whose Registrable Securities are included in the Registration Statement (which notice shall not contain any material, non-public information regarding the Company), suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement but may settle any previously made sales of Registrable Securities) if (i) the Company determines that it would be required to make disclosure of material information in the Registration Statement that the Company has a bona fide business purpose for preserving as confidential or (ii) the Company determines in good faith that a postponement is in the best interest of the Company and its stockholders generally due to a pending transaction involving the Company (including a pending securities offering by the Company, or any proposed financing, acquisition, merger, tender offer, business combination, corporate reorganization, consolidation or other significant transaction involving the Company); provided, however, in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Registration for more than 45 consecutive days or for a total of more than 90 days in any 365 day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

Section 2.04 Sale Procedures.

(a) In connection with its obligations under this ARTICLE II, the Company will, as expeditiously as possible:

(i) prepare and file with the Commission such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by the Registration Statement;

(ii) make available to each Selling Holder (x) as far in advance as reasonably practicable before filing the Registration Statement or any supplement or amendment thereto, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and the Company shall make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Registration Statement or supplement or amendment thereto, and (y) such number of copies of the Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Selling Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement;

(iii) if applicable, use its reasonable best efforts to register or qualify the Registrable Securities covered by the Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably request in writing by the time the Registration Statement is declared effective by the Commission; provided, however, that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject;

(iv) promptly (but in no event later than 24 hours) notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act (which notice shall not contain any material, non-public information regarding the Company), of (x) the filing of the Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any post-effective amendment thereto, when the same has become effective; and (y) the receipt of any written comments from the Commission with respect to any filing referred to in clause (x) and any written request by the Commission for amendments or supplements to the Registration Statement or any prospectus or prospectus supplement thereto;

Following the occurrence of any of the events set forth in clauses (x) through (z) above, the Company agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an 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 in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(vi) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to the Registration Statement;

(xi) if requested by a Selling Holder, (x) incorporate in a prospectus supplement or post-effective amendment such information as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering and (y) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment;

(xii) otherwise use reasonable best efforts to comply with all applicable rules and regulations of the Commission under the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final prospectus, including any supplement or amendment thereof, with the Commission pursuant to Rule 424 under the Securities Act, promptly inform the Holders in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Holders are required to deliver a prospectus in connection with any disposition of Registrable Securities pursuant to any Registration Statement and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder, and make available to its security holders, as soon as reasonably practicable, but not later than the Availability Date (as defined below), an earnings statement covering a period of at least 12 months, beginning after the effective date of each Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act, including Rule 158

Section 2.05 Cooperation by Holders. The Company shall have no obligation to include in the Registration Statement Registrable Securities of a Holder who has failed to timely furnish such information that the Company determines, after consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.06 Confirmation of Effectiveness. If requested by a Holder at any time in respect of any Registration Statement, the Company shall deliver to such Holder a written confirmation from Company’s counsel of whether or not the effectiveness of such Registration Statement has lapsed at any time for any reason (including, without limitation, the issuance of a stop order) and whether or not such Registration Statement is currently effective and available to the Company for sale of Registrable Securities.

Section 2.07 Holder Review. The Company will not file any amendment or supplement to the Registration Statement or any prospectus, other than documents incorporated by reference, relating to the Holders, the Registrable Securities or the transactions contemplated hereby unless (a) the Holders and their counsel shall have been advised and afforded the opportunity to review and comment thereon at least three Business Days prior to filing with the Commission and (b) the Company shall have given reasonable due consideration to any comments thereon received from the Holders or their counsel.

Section 2.08 Expenses. The Company will pay all reasonable Registration Expenses as determined in good faith.

of Registrable Securities on the Registration Statement pursuant to Section 2.01, and the disposition of such Registrable Securities, including, without limitation, all registration, filing, securities exchange listing and NYSE fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, any transfer taxes, the fees and disbursements of counsel and independent public accountants for the Company, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance, and the reasonable fees and disbursements of one counsel in connection with the transactions contemplated by this Agreement for the Holders who are initial Purchasers of Common Stock under the Common Stock Subscription Agreement.

Section 2.09 Indemnification.

(a) Indemnification by the Company. In the event of any registration of any securities of the Company under the Securities Act pursuant to this Agreement, the Company will, and hereby does, indemnify and hold harmless each Selling Holder of any Registrable Securities covered by such Registration Statement, its affiliates and its and their directors, officers, managers, partners, members, employees, investment advisers and agents, each other Person who participates in the offering or sale of such Registrable Securities, each other Person, if any, who controls such Selling Holder, within the meaning of the Securities Act, and the directors, officers, managers, partners, members, employees, investment advisers and agents of such controlling person (collectively, “Selling Holder Indemnified Persons”) promptly upon demand against any losses, claims, damages or liabilities (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject, under the Securities Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and/or any violation or alleged violation by the Company or any of its subsidiaries of the Securities Act, Exchange Act or any other state securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered or any rule or regulation promulgated thereunder applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration of the Registrable Securities, and the Company will reimburse such Selling Holder Indemnified Person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such Loss, action or proceeding promptly upon demand; provided that the Company shall not be liable in any such case to the extent that any such Loss (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with information furnished by such Selling Holder to the Company in writing or electronically for use in the preparation thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of Selling Holder Indemnified Person and shall survive the transfer of such securities by such Selling Holder.

(b) Indemnification by the Sellers. The Company may require, as a condition to including any Registrable Securities in any registration statement filed pursuant to Section 2.01, that the Company shall have received an undertaking satisfactory to it from the prospective seller of such securities to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 2.09(a)) the Company, each director of the Company, each officer of the Company and each other Person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with information furnished by such seller to the Company in writing or electronically for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement. The maximum liability of each seller for any such indemnification shall not exceed the amount of net proceeds received by such seller from the sale of such seller’s Registrable Securities. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling Person and shall survive the transfer of such securities by such seller.

(c) Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in Section 2.09(a) or (b), such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under Section 2.09(a) or (b), except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the 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 from all liability in respect to such claim or litigation.

(d) Other Indemnification. Indemnification similar to that specified in Section 2.09(a), (b) and (c) (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of securities under any federal or state law or regulation of any governmental authority other than the Securities Act.

(e) Indemnification Payments. The indemnification required by this Section 2.09 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense or Loss is incurred.

Section 2.10 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to:

(a) make and keep adequate current public information regarding the Company available, as those terms are understood and defined in Rule 144, at all times from and after the date hereof;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c) so long as a Holder owns any Registrable Securities, furnish, unless otherwise available via ▇▇▇▇▇, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.11 Transfer or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities granted to the Purchasers by the Company under this ARTICLE II may be transferred or assigned by any Purchaser to one or more transferees or assignees of Registrable Securities; provided, however, that (a) unless the transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Purchaser, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall represent at least $10 million of Registrable Securities (based on the Common Stock Price) or, if less, 100% of the Registrable Securities then held by such Purchaser, (b) the Company is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned, (c) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Purchaser under this Agreement and (d) the transferor or assignor is not relieved of any obligations or liabilities hereunder arising out of events occurring prior to such transfer. The Company shall not assign this Agreement or any rights or obligations hereunder (whether by operation of law or otherwise) without the prior written consent of the Holders holding at least a majority or Registrable Securities.

ANY ACTION AGAINST ANY PARTY RELATING TO THE FOREGOING SHALL BE BROUGHT IN ANY FEDERAL OR STATE COURT OF COMPETENT JURISDICTION LOCATED WITHIN THE STATE OF NEW YORK, AND THE PARTIES HERETO HEREBY IRREVOCABLY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF ANY FEDERAL OR STATE COURT LOCATED WITHIN THE STATE OF NEW YORK OVER ANY SUCH ACTION. THE PARTIES HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT THEY MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH DISPUTE BROUGHT IN SUCH COURT OR ANY DEFENSE OF INCONVENIENT FORUM FOR THE MAINTENANCE OF SUCH DISPUTE. EACH OF THE PARTIES HERETO AGREES THAT A JUDGMENT IN ANY SUCH DISPUTE MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.

Section 3.10 Severability of Provisions. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing the validity or enforceability of such provision in any other jurisdiction.

Section 3.11 Entire Agreement. This Agreement and the Common Stock Subscription Agreement are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by the Company set forth herein. This Agreement supersedes all prior agreements and understandings between the parties with respect to such subject matter.

Section 3.12 Amendment. This Agreement may be amended only by means of a written amendment signed by the Company and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall adversely affect the rights of any Holder hereunder without the consent of such ▇▇▇▇▇▇.

Section 3.13 No Presumption. If any claim is made by a party relating to any conflict, omission or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel.

Section 3.14 Obligations Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and acknowledges that no Person other than the Purchasers (and their permitted transferees and assignees) and the Company shall have any obligation hereunder and that, notwithstanding that one or more of the Purchasers may be a corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Purchasers or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Purchasers or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of the Purchasers under this Agreement or any documents or instruments delivered in connection herewith or therewith or for any claim based on, in respect of or by reason of such obligation or its creation, except in each case for any transferee or assignee of a Purchaser hereunder.

Section 3.15 Independent Nature of Purchaser’s Obligations. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with this Agreement and that no Purchaser will be acting as agent of such Purchaser in connection with enforcing its rights under this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

The failure or waiver of performance by any Purchaser does not excuse performance by any other Purchaser. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

Section 3.16 Interpretation. Unless otherwise specified, references to Articles, Sections and Annexes are to Articles, Sections and Annexes of this Agreement. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever any determination, consent or approval is to be made or given by a Purchaser under this Agreement, such action shall be in such Purchaser’s sole discretion unless otherwise specified.

Section 3.17 Effectiveness; Termination. This Agreement shall not be effective, and no party hereto shall have any obligations hereunder, unless and until the closing under the Common Stock Subscription Agreement shall have occurred. This Agreement shall automatically terminate upon termination of the Common Stock Subscription Agreement.
