REGISTRATION RIGHTS

SECTION 7.1 Demand Registration.

(a) General Request for Registration. At any time during the Registration Period, any Requesting Party may make a written demand for registration under the 1933 Act of twenty-five percent (25%) or more of the Registrable Securities owned by the Requesting Parties, in aggregate. Any such written demand for a registration shall specify the number of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company shall provide a copy of any such written demand to each other Requesting Party and each such other Requesting Party shall have the option to join in such demand for registration by making its own written demand for a Demand Registration to the Company within five (5) Business Days thereafter. The registration so demanded by one or more Requesting Parties is referred to herein as a “Demand Registration” and the Requesting Parties making such requests as “Demanding Shareholders.” If the Company is eligible to utilize a Registration Statement on Form S-3 to sell

securities in a secondary offering on a delayed or continuous basis in accordance with Rule 415 under the 1933 Act (a “Shelf Registration”), any Demand Registration made pursuant to this Section 7.1(a) shall, at the option of Demanding Shareholder(s) holding a majority of the Registrable Securities subject to the Demand Registration, be a demand for a Shelf Registration. For the avoidance of doubt, if a Shelf Registration is so requested pursuant to this Section 7.1(a), any reference to a Demand Registration in this Agreement also refers to a Shelf Registration.

(b) Underwritten Offering. If Demanding Shareholder(s) holding a majority of the Registrable Securities subject to the Demand Registration so advise the Company as part of their written demand(s) for a Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering. In such case, each Demanding Shareholder shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such underwriting by the Requesting Parties holding a majority of the Registrable Securities subject to the Demand Registration (which Underwriter(s) shall be reasonably acceptable to the Company), complete and execute any questionnaires, powers of attorney, indemnities, lock-up agreements, securities escrow agreements and other documents reasonably required or which are otherwise customary under the terms of such underwriting agreement and furnish to the Company such information as the Company may reasonably request in writing for inclusion in the Registration Statement.

(c) Reduction of Offering. If the managing Underwriter(s) for a Demand Registration that is to be an underwritten offering advise(s) the Company and each Demanding Shareholder that the dollar amount or number of Registrable Securities which Demanding Shareholder(s) desire(s) to sell, taken together with all other Common Shares or other securities which Demanding Shareholder(s) have agreed may be included in the offering, exceeds the maximum dollar amount or maximum number of Common Shares or other securities that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method or the probability of success of such offering (such maximum dollar amount or maximum number of Common Shares or other securities, as applicable, the “Registered Offering Cap”), then the Company shall include in such registration: (i) first, the Registrable Securities which Demanding Shareholder(s) have demanded be included in the Demand Registration; provided, however, if the aggregate number of Registrable Securities as to which Demand Registration has been requested exceeds the Registered Offering Cap, then the number of Registrable Securities that may be included shall be reduced to the Registered Offering Cap and the participation in the Demand Registration shall be allocated to Demanding Shareholders pro rata (in accordance with the number of Registrable Securities which each Demanding Shareholder has requested be included in the Demand Registration); (ii) second, to the extent that the Registered Offering Cap has not been reached under the foregoing clause (i), the Common Shares or other securities that the Company desires to sell that can be sold without exceeding the Registered Offering Cap; and (iii) third, to the extent that the Registered Offering Cap has not been reached under the foregoing clauses (i) and (ii), the Common Shares or other securities for the account of other security holders of the Company that can be sold without exceeding the Registered Offering Cap.

(d) Withdrawal. In the case of a Demand Registration, if a Demanding Shareholder disapproves of the terms of any underwriting or is not entitled to include all of its Registrable Securities in any offering, such Demanding Shareholder may elect to withdraw from such offering no later than the time at which the public offering price and underwriters’ discount are determined with the Underwriter(s) by giving written notice to the Company and the Underwriter(s) of its request to withdraw. In such event, if there are no other Requesting Parties included in the Demand Registration, the Company need not proceed with the offering. If such Demanding Shareholder’s withdrawal is based on (i) a material adverse change in circumstances with respect to the Company and not known to such Demanding Shareholder at the time such Demanding

Shareholder makes its written demand for such Demand Registration, (ii) the Company’s failure to comply with its obligations under this Agreement or (iii) a reduction pursuant to Section 7.1(c) of ten percent (10%) or more of the number of Registrable Securities which Demanding Shareholder has requested be included in the Demand Registration, such registration shall not count as a Demand Registration for purposes of Section 8.1(a)(3) or Section 8.1(a)(5). If such Demanding Shareholder’s withdrawal is based on the circumstances described in clause (i) or (ii) of the preceding sentence, the Company shall pay or reimburse all expenses otherwise payable or reimbursable by the Demanding Shareholder in connection with such Demand Registration pursuant to Section 8.3 and such registration shall not count as a Demand Registration for purposes of Section 8.1(a)(3) or Section 8.1(a)(5).

SECTION 7.2 Piggy-Back Registration.

(a) Piggy-Back Rights. If, at any time during the Registration Period, the Company proposes to file a Registration Statement under the 1933 Act with respect to an offering of Common Shares, or securities or other obligations exercisable or exchangeable for, or convertible into, Common Shares, by the Company for its own account or for any other shareholder of the Company for such shareholder’s account, other than a Registration Statement (i) filed in connection with any employee benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering of debt securities convertible into equity securities of the Company, (iv) for a dividend reinvestment plan or (v) filed on Form S-4 (or successor form), then the Company shall (x) give written notice of such proposed filing to each Requesting Party as soon as practicable but in no event less than ten (10) Business Days before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter(s), if any, of the offering and (y) offer to each Requesting Party in such notice the opportunity to register the sale of such number of its Registrable Securities as such Requesting Party may request in writing within five (5) Business Days following receipt of such notice (a “Piggy-Back Registration”). If a Requesting Party so requests to register the sale of some of its Registrable Securities, the Company shall cause such Registrable Securities to be included in the Registration Statement and shall use commercially reasonable efforts to cause the managing Underwriter(s) of the proposed underwritten offering to permit the Registrable Securities requested to be included in the Piggy-Back Registration to be included on the same terms and conditions as any similar securities of the Company and other shareholders of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. If the Piggy-Back Registration involves one or more Underwriters, each Requesting Party shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Piggy-Back Registration by the Company, complete and execute any questionnaires, powers of attorney, indemnities, lock-up agreements, securities escrow agreements and other documents reasonably required or which are otherwise customary under the terms of such underwriting agreement and furnish to the Company such information as the Company may reasonably request in writing for inclusion in the Registration Statement or such information that is otherwise customary.

(b) Reduction of Offering. If the managing Underwriter(s) for a Piggy-Back Registration that is to be an underwritten offering advises the Company and the holders of Registrable Securities that the dollar amount or number of Common Shares or other securities which the Company desires to sell, taken together with Common Shares or other securities, if any, as to which registration has been requested pursuant to written contractual arrangements with Requesting Parties and other Persons, the Registrable Securities as to which registration has been requested under this Section 7.2, and the Common Shares or other securities, if any, as to which registration has been requested pursuant to the written contractual demand or piggy-back

registration rights of other shareholders of the Company, exceeds the Registered Offering Cap, then the Company shall include in any such registration:

(1) If the registration is undertaken for the Company’s account: (x) first, the shares or other securities that the Company desires to sell that can be sold without exceeding the Registered Offering Cap; and (y) second, to the extent that the Registered Offering Cap has not been reached under the foregoing clause (x), the shares or other securities, if any, including the Registrable Securities, as to which registration has been requested pursuant to written contractual piggy-back registration rights of security holders (pro rata in accordance with the number of Common Shares or other securities which each such person has actually requested to be included in such registration, regardless of the number of shares or other securities with respect to which such persons have the right to request such inclusion) that can be sold without exceeding the Registered Offering Cap; and

(2) If the registration is a “demand” registration undertaken at the demand of Persons, other than a Requesting Party or Permitted Transferee, pursuant to written contractual arrangements with such Persons, (x) first, the Common Shares or other securities for the account of the demanding Persons that can be sold without exceeding the Registered Offering Cap; (y) second, to the extent that the Registered Offering Cap has not been reached under the foregoing clause (x), the Common Shares or other securities that the Company desires to sell that can be sold without exceeding the Registered Offering Cap; and (z) third, to the extent that the Registered Offering Cap has not been reached under the foregoing clauses (x) and (y), the shares or other securities, if any, including the Registrable Securities, as to which registration has been requested pursuant to written contractual piggy-back registration rights, which other shareholders desire to sell (pro rata in accordance with the number of Common Shares or other securities which each such Person has actually requested to be included in such registration, regardless of the number of Common Shares or other securities with respect to which such persons have the right to request such inclusion) that can be sold without exceeding the Registered Offering Cap.

(c) Withdrawal. Any Requesting Party may elect to withdraw its request for inclusion of its Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw no later than the time at which the public offering price and underwriters’ discount are determined with the Underwriter(s). The Company may also elect to withdraw from a registration at any time no later than the time at which the public offering price and underwriters’ discount are determined with the Underwriter(s). If a Requesting Party’s withdrawal is based on the Company’s failure to comply with its obligations under this Agreement, the Company shall pay or reimburse all expenses otherwise payable or reimbursable by such Requesting Party in connection with such Piggy-Back Registration pursuant to Section 8.3.

ARTICLE VIII

REGISTRATION PROCEDURES

SECTION 8.1 Filings; Information. Whenever the Company is required to effect the registration of any Registrable Securities pursuant to Article VII, the Company shall use its commercially reasonable efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method(s) of distribution thereof as expeditiously as practicable, and in connection with any such request:

(a) Filing Registration Statement. The Company shall, as expeditiously as possible and in any event within sixty (60) days after receipt of a request for a Demand Registration pursuant to Section 7.1, prepare and file with the SEC a Registration Statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form

shall be available for the sale of all Registrable Securities to be registered thereunder and the intended method(s) of distribution thereof, and shall use commercially reasonable efforts to cause such Registration Statement to become and remain effective for the period required by Section 8.1(c); provided, however, that:

(1) In the case of demand under Section 7.1 for a Shelf Registration, the Registration Statement shall be on Form S-3;

(2) the Company shall have the right to defer any Demand Registration and any Piggy-Back Registration for a reasonable period of time if, in the good faith judgment of the Board of Directors or the officers of the Company (and the Company shall furnish to the holders a confirmatory certificate signed by a principal executive officer or principal financial officer of the Company), it would (A) materially interfere with a significant acquisition, disposition, financing or other transaction involving the Company, (B) result in the disclosure of material information that the Company has a bona fide business purpose for preserving as confidential that is not then otherwise required to be disclosed or (C) render the Company unable to comply with requirements under the 1933 Act or the 1934 Act; in such event, (i) if the applicable Registration Statement has become effective, each Requesting Party will forthwith discontinue (or cause the discontinuance of) disposition of Registrable Securities until it is advised by the Company that the use of such Registration Statement may be resumed or (ii) each Requesting Party shall be entitled to withdraw its request for the filing of the applicable Registration Statement and, if such request is withdrawn, such request shall not count as one of the permitted requests for registration hereunder and the Company shall pay all customary costs and expenses in connection with such withdrawn registration; provided, further, however, that the Company may not exercise the right set forth in this subsection (2) in respect of a request by a Requesting Party, for more than one hundred eighty (180) days in any 365-day period in respect of a Demand Registration (including in such one hundred eighty (180) days, any deferral under subsection (4) of this Section 8.1(a) if the Registration Statement was not timely filed thereunder);

(3) the Company shall not be obligated to effect any registration of Registrable Securities upon receipt of a written demand for a Demand Registration if the Company has already completed two (2) Demand Registrations requested by a Requesting Party within the past twelve (12) month period;

(4) the Company shall not then be obligated to effect any registration of Registrable Securities upon receipt of a written demand for a Demand Registration if the Company shall furnish to the demanding Requesting Parties a certificate signed by a principal executive officer or principal financial officer of the Company stating that the Company expects to file, within ninety (90) days of receipt of the written demand for a Demand Registration, a Registration Statement and offer to each Requesting Party the opportunity to register its Registrable Securities thereunder in accordance with Section 7.2;

(5) the Company shall not be obligated to effect any registration of Registrable Securities upon receipt of a written demand for a Demand Registration from a Requesting Party if the Company has, within the ninety (90) day period preceding the date of the written demand for a Demand Registration, already effected a Demand Registration;

(6) the Company shall not be obligated to effect any registration of Registrable Securities upon receipt of a written demand for a Demand Registration if all Registrable Securities could be sold within ninety (90) days pursuant to Rule 144 under the 1933 Act; and

(7) the Company shall not be obligated to effect any registration of Registrable Securities upon receipt of a written demand for a Demand Registration if all Registrable

Securities are proposed to be offered at an expected aggregate offering price of less than $50.0 million (net of registration expenses set forth in Section 8.3), provided, that this clause (7) shall not apply to a Shelf Registration.

(b) Copies. If a Requesting Party has included Registrable Securities in a registration, the Company shall, prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish to such Requesting Party and its counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as such Requesting Party or counsel for such Requesting Party may reasonably request in order to facilitate the disposition of the Registrable Securities included in such registration.

(c) Amendments and Supplements. If a Requesting Party has included Registrable Securities in a registration, the Company shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and in compliance with the provisions of the 1933 Act until all Registrable Securities covered by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration Statement (which period shall not exceed the sum of one hundred eighty (180) days, plus any period during which any such disposition is interfered with by any stop order or injunction of the SEC or any Governmental Entity) or such securities have been withdrawn.

(d) Notification. If a Requesting Party has included Registrable Securities in a registration, after the filing of the Registration Statement, the Company shall promptly, and in no event more than two (2) Business Days after such filing, notify such Requesting Party of such filing, and shall further notify such Requesting Party promptly and confirm such notification in writing in all events within two (2) Business Days of the occurrence of any of the following: (i) when such Registration Statement becomes effective; (ii) when any post-effective amendment to such Registration Statement becomes effective; (iii) the issuance or threatened issuance by the SEC of any stop order (and the Company shall use reasonable best efforts to prevent the entry of such stop order or to remove it if entered); and (iv) any request by the SEC for any amendment or supplement to such Registration Statement or any Prospectus relating thereto or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such Prospectus so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement, such Prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and promptly make available to such Requesting Party any such supplement or amendment; except that before filing with the SEC a Registration Statement or Prospectus or any amendment or supplement thereto, including documents incorporated by reference, the Company shall furnish to such Requesting Party and to its counsel, copies of all such documents proposed to be filed sufficiently in advance of filing to provide such Requesting Party and its counsel with a reasonable opportunity to review such documents and comment thereon, and the Company shall not file any Registration Statement or Prospectus or amendment or supplement thereto, including documents incorporated by reference, to which such Requesting Party or its counsel shall reasonably object.

(e) State Securities Laws Compliance. If a Requesting Party has included Registrable Securities in a registration, the Company shall use commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as such Requesting Party (in light of the

intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other federal or state authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable such Requesting Party to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 8.1(e) or subject itself to taxation in any such jurisdiction.

(f) Agreements for Disposition. If a Requesting Party has included Registrable Securities in a registration, (i) the Company shall enter into customary agreements (including, if applicable, an underwriting agreement in customary form) and use commercially reasonable efforts to take such other actions as are required in order to expedite or facilitate the disposition of such Registrable Securities and (ii) the representations, warranties and covenants of the Company in any underwriting agreement which are made to or for the benefit of any Underwriters, to the extent applicable, shall also be made to and for the benefit of the applicable Requesting Parties. For the avoidance of doubt, no Requesting Party may require the Company to accept terms, conditions or provisions in any such agreement which the Company determines are not reasonably acceptable to the Company, notwithstanding any agreement to the contrary herein. No Requesting Party including Registrable Shares in a registration shall be required to make any representations or warranties in the underwriting agreement except as reasonably requested by the Underwriters or the Company and, if applicable, with respect to such Requesting Party’s organization, good standing, authority, title to Registrable Securities, lack of conflict of such sale with such Requesting Party’s material agreements and organizational documents, and with respect to written information relating to such Requesting Party that such Requesting Party has furnished in writing expressly for inclusion in such Registration Statement, in each case, as applicable to such Requesting Party. Each Requesting Party which has included Registrable Securities in a registration shall, however, agree to such covenants and indemnification and contribution obligations for selling stockholders as are reasonable and customarily contained in agreements of that type.

(g) Cooperation. The Company shall cooperate in any offering of Registrable Securities under this Agreement, which cooperation shall include, without limitation, the preparation of the Registration Statement with respect to such offering and all other offering materials and related documents, and participation in meetings with Underwriters, attorneys, accountants and potential investors. Each Requesting Party shall cooperate in the preparation of the Registration Statement and other documents relating to any offering in which it includes securities pursuant to this Agreement. If a Requesting Party has included Registrable Securities in a registration, such Requesting Party shall also furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method(s) of disposition of such securities as the Company and/or its counsel shall reasonably request in order to assure full compliance with applicable provisions of the 1933 Act and the 1934 Act in connection with the registration of the Registrable Securities.

(h) Records. If a Requesting Party has included Registrable Securities in a registration, upon reasonable notice and during normal business hours, subject to the Company receiving any customary confidentiality undertakings or agreements, the Company shall make available for inspection by Requesting Parties, any Underwriter participating in any disposition pursuant to such Registration Statement and any attorney, accountant or other professional retained by a Requesting Party or any Underwriter, all relevant financial and other records, pertinent corporate documents and properties of the Company as shall be necessary to enable them to exercise their due diligence responsibility, and shall cause the Company’s officers, directors and employees to

supply all information reasonably requested by such Requesting Party in connection with such Registration Statement.

(i) Opinions and Comfort Letters. If a Requesting Party has included Registrable Securities in a registration, the Company shall use commercially reasonable efforts to furnish to each Requesting Party signed counterparts, addressed to such Requesting Party, of (i) any opinion of counsel to the Company delivered to any Underwriter and (ii) any comfort letter from the Company’s independent public accountants delivered to any Underwriter; provided, however, that counsel to the Underwriter shall have exclusive authority to negotiate the terms thereof. In the event no legal opinion is delivered to any Underwriter, the Company shall furnish to each Requesting Party, at any time that such Requesting Party elects to use a Prospectus in connection with an offering of such Requesting Party’s Registrable Securities, an opinion of counsel to the Company to the effect that the Registration Statement containing such Prospectus has been declared effective, that no stop order is in effect, and such other matters as Persons holding a majority of the Registrable Securities subject to the registration may reasonably request as would customarily have been addressed in an opinion of counsel to the Company delivered to an Underwriter.

(j) Earning Statement. The Company shall comply with all applicable rules and regulations of the SEC and the 1933 Act, and make generally available to its shareholders, as soon as practicable, an earning statement satisfying the provisions of Section 11(a) of the 1933 Act, provided that the Company will be deemed to have complied with this Section 8.1(j) if the earning statement satisfies the provisions of Rule 158 under the 1933 Act.

(k) Listing. The Company shall use commercially reasonable efforts to cause all Registrable Securities included in any registration to be listed on such exchanges or otherwise designated for trading in the same manner as similar shares of the Company are then listed or designated or, if no such similar securities are then listed or designated, in a manner satisfactory to each Requesting Party whose Registrable Securities are included in the registration.

SECTION 8.2 Shelf Offering. In the event that a Registration Statement with respect to a Shelf Registration is effective, each Requesting Party may make a written request to sell pursuant to an offering (including an underwritten offering) Registrable Securities available for sale pursuant to such Registration Statement (a “Shelf Offering”) so long as such Registration Statement remains in effect and to the extent permitted under the 1933 Act. Any written request for a Shelf Offering shall specify the number of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. Upon receipt of a written request for a Shelf Offering, the Company shall, as expeditiously as possible, use its commercially reasonable efforts to facilitate such Shelf Offering.

SECTION 8.3 Registration Expenses. Except to the extent expressly provided by Section 7.1(d) or Section 7.2(c) or in connection with a Piggy-Back Registration relating to a registration by the Company on its own initiative (and not as a result of any other person’s or entity’s right to cause the Company to file, cause and effect a registration of the Company securities) and for the Company’s own account (in which case the Company will pay all customary costs and expenses of registration), each Requesting Party whose Registrable Securities are included in the registration shall pay, or promptly reimburse the Company for, its pro rata share of all customary costs and expenses incurred in connection with any Demand Registration effected pursuant to Section 7.1 or Piggy-Back Registration pursuant to Section 7.2, such pro rata share to be in proportion to the number of shares such Requesting Party is selling, after giving effect to any reduction pursuant to Section 7.1(c) or Section 7.2(b), in such Demand or Piggy-Back Registration relative to the total number of shares being sold in the registration, of all customary costs and expenses incurred in connection with such registration, in each case whether or not the Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees; (ii) fees and expenses of compliance with

securities or “blue sky” laws (including fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities); (iii) printing expenses; (iv) fees imposed by the Financial Industry Regulatory Authority, Inc.; and (v) fees and disbursements of counsel for the Company and fees and expenses for independent registered public accountants retained by the Company (including the expenses or costs associated with the delivery of any opinions or comfort letters requested pursuant to Section 8.1(i)). The Company shall have no obligation to pay for the fees and expenses of counsel representing any Requesting Party in any Demand Registration or Piggy-Back Registration. The Company shall have no obligation to pay any underwriting discounts or selling commissions attributable to the Registrable Securities being sold by any Requesting Party, which underwriting discounts or selling commissions shall be borne solely by such Requesting Party. For the avoidance of doubt, no Requesting Party shall have any obligation to pay any underwriting discounts or selling commissions attributable to the shares being sold by any other Person. Additionally, in an underwritten offering, the Company, the Requesting Parties and any other Person whose Common Shares or other securities are included in the offering shall bear the expenses of the Underwriter(s) pro rata in proportion to the respective amount of shares each is selling in such offering. For the avoidance of doubt, no Requesting Party shall have any obligation to pay, and the Company shall bear, all internal expenses of the Company (including, without limitation, all fees, salaries and expenses of its officers, employees and management) incurred in connection with performing or complying with the Company’s obligations under this Agreement.

SECTION 8.4 Information. Each Requesting Party shall provide such information as may reasonably be requested by the Company, or the managing Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the registration of any of its Registrable Securities under the 1933 Act pursuant to this Agreement and in connection with the Company’s obligation to comply with federal and applicable state securities laws.

SECTION 8.5 Requesting Party Obligations. No Requesting Party may participate in any underwritten offering pursuant to this Agreement unless such Requesting Party (i) agrees to only sell Registrable Securities on the basis reasonably provided in any underwriting agreement and (ii) completes, executes and delivers any and all questionnaires, lock-up agreements, powers of attorney, custody agreements, indemnities, underwriting agreements and other documents reasonably or customarily required by or under the terms of any underwriting agreement or as reasonably requested by the Company.

SECTION 8.6 Lock-Up in an Underwritten Public Offering. If requested by the Underwriter(s) of a registered underwritten public offering of securities of the Company, a Requesting Party will enter into a lock-up agreement in customary form pursuant to which it shall agree not to offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer, dispose of or hedge, directly or indirectly, or enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of any Common Shares or other securities of the Company or any securities convertible into or exercisable or exchangeable for Common Shares or other securities of the Company (except as part of such registered underwritten public offering or as otherwise permitted by the terms of such lock-up agreement) for a lock-up period that is customary for such an offering.

ARTICLE IX

INDEMNIFICATION

SECTION 9.1 Indemnification by the Company. The Company shall, to the extent permitted by applicable Law, indemnify and hold harmless each Requesting Party, its subsidiaries, each of their respective directors, trustees, officers, employees, Representatives and agents in their capacity as such

and each Person, if any, who controls a Requesting Party within the meaning of the 1933 Act or the 1934 Act, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “Indemnified Requesting Persons”) from and against any and all damages, claims, losses, expenses, costs, obligations and liabilities, including liabilities for all reasonable attorneys’, accountants’, and experts’ fees and expenses (collectively, “Covered Liabilities”), suffered, directly or indirectly, by any Indemnified Requesting Person by reason of or arising out of any untrue statement or alleged untrue statement of any material fact contained or incorporated by reference in the Registration Statement under which the sale of Registrable Securities was registered under the 1933 Act (or any amendment thereto), or any Prospectus, preliminary Prospectus, or free writing prospectus (as defined in Rule 405 promulgated under the 1933 Act) relating to such Registration Statement, or any amendment thereof or supplement thereto, or by reason of or arising out of the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or any amendment or supplement thereto, in the light of the circumstances under which they were made), not misleading; provided, however, that (i) the Company will not be liable in any such case to the extent that any such Covered Liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made or incorporated by reference in such Registration Statement, Prospectus, preliminary Prospectus, free writing prospectus, amendment or supplement in reliance upon and in conformity with information furnished to the Company by or on behalf of such Requesting Party expressly for use in such document or documents and (ii) the indemnity agreement contained in this Section 9.1 shall not apply to amounts paid in settlement of any such Covered Liability if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld). The indemnity in this Section 9.1 shall remain in full force and effect regardless of any investigation made by or on behalf of any Indemnified Requesting Person. For the avoidance of doubt, the Company and its subsidiaries are not “Indemnified Requesting Persons.”

SECTION 9.2 Indemnification by Requesting Parties. Each Requesting Party shall, severally and not jointly, to the extent permitted by applicable Law, indemnify and hold harmless the Company, its subsidiaries each of their respective trustees, directors, officers, employees, Representatives and agents, in their capacity as such and each Person, if any, who controls the Company within the meaning of the 1933 Act or the 1934 Act, and the heirs, executors, successors and assigns of any of the foregoing (collectively, the “Indemnified Company Persons”) from and against any and all Covered Liabilities suffered, directly or indirectly, by any Indemnified Company Person by reason of or arising out of any untrue statement or alleged untrue statement or omission or alleged omission contained or incorporated by reference in the Registration Statement under which the sale of Registrable Securities was registered under the 1933 Act (or any amendment thereto), or any Prospectus, preliminary Prospectus, or free writing prospectus (as defined in Rule 405 promulgated under the 1933 Act) related to such Registration Statement or any amendment thereof or supplement thereto, in reliance upon and in conformity with information furnished to the Company by such Requesting Party expressly for use therein; provided, however, that (i) the indemnity agreement contained in this Section 9.2 shall not apply to amounts paid in settlement of any such Covered Liability if such settlement is effected without the consent of such Requesting Party (which consent shall not be unreasonably withheld), and (ii) in no event shall the total amounts payable in indemnity by a Requesting Party under this Section 9.2 exceed the net proceeds received by such Requesting Party in the registered offering out of which such Covered Liability arises. The indemnity in this Section 9.2 shall remain in full force and effect regardless of any investigation made by or on behalf of any Indemnified Company Person. For the avoidance of doubt, a Requesting Party is not an “Indemnified Company Person.”

SECTION 9.3 Contribution. If the indemnification provided for in Section 9.1 or Section 9.2 is unavailable, because it is prohibited or restricted by applicable Law, to an indemnified party under either such Section in respect of any Covered Liabilities referred to therein, then in order to provide for just and equitable contribution in such circumstances, each party that would have been an indemnifying party thereunder shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such Covered Liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and such indemnified party on the other in connection with the untrue statement or omission, or alleged untrue statement or omission, which resulted in such Covered Liabilities, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or such indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Requesting Parties agree that it would not be just and equitable if contribution pursuant to this Section 9.3 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9.3. For the avoidance of doubt, the amount paid or payable by an indemnified party as a result of the Covered Liabilities referred to in this Section 9.3 shall include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing or defending, settling or satisfying any such Covered Liability. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

SECTION 9.4 Certain Limitations, Etc. The amount of any Covered Liabilities for which indemnification is provided under this Agreement shall be net of (i) any amounts actually recovered or recoverable by the indemnified parties under insurance policies and (ii) other amounts actually recovered by the indemnified party from third parties, in the case of (i) and (ii), with respect to such Covered Liabilities. Any indemnifying party hereunder shall be subrogated to the rights of the indemnified party upon payment in full of the amount of the relevant indemnifiable loss. An insurer who would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto or, solely by virtue of the indemnification provision hereof, have any subrogation rights with respect thereto. If any indemnified party recovers an amount from a third party in respect of an indemnifiable loss for which indemnification is provided in this Agreement after the full amount of such indemnifiable loss has been paid by an indemnifying party or after an indemnifying party has made a partial payment of such indemnifiable loss and the amount received from the third party exceeds the remaining unpaid balance of such indemnifiable loss, then the indemnified party shall promptly remit to the indemnifying party the excess of (i) the sum of the amount theretofore paid by such indemnifying party in respect of such indemnifiable loss plus the amount received from the third party in respect thereof, less (ii) the full amount of such Covered Liabilities.

This Agreement (including the documents and instruments referred to in this Agreement or entered into in connection therewith) constitute the entire agreement of the Parties and supersede all prior agreements, arrangements or understandings, whether written or oral, between the Parties with respect to the subject matter of this Agreement.

SECTION 10.4 Governing Law; Venue; Arbitration.

(a) Governing Law. This Agreement and all proceedings or counterclaims (whether based in contract, tort or otherwise) arising out of or relating to this Agreement or the transactions contemplated hereby, or any action of any Party in the negotiation, administration, performance and enforcement hereof, shall be governed by, and construed in accordance with, the Laws of the State of Maryland, without giving effect to any choice or conflict of laws provision or rule (whether of the State of Maryland or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Maryland.

(b) Venue. All claims, actions, suits, dispute resolution, judicial and other legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby or any action of any Party, Collateral Person or Related Person (each a “Subject Party”) in the negotiation, administration, performance and enforcement hereof shall be heard and determined exclusively in the Business and Technology Case Management Program of the Circuit Court for Baltimore City, Maryland or the U.S. District Court for Maryland (collectively, the “Chosen Courts”). Each Subject Party hereby expressly and irrevocably (i) submits to the exclusive personal jurisdiction of the Chosen Courts in the event any claim or dispute arising out of or relating to this Agreement or the transactions contemplated hereby, or any action of any Subject Party in the negotiation, administration, performance and enforcement hereof, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from the Chosen Courts, (iii) agrees that it will not bring any proceeding arising out of or relating to this Agreement or the transactions contemplated hereby, or any action of any Subject Party in the negotiation, administration, performance and enforcement hereof, in any court other than the Chosen Courts, (iv) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding in the Chosen Courts, (v) agrees that a final judgment in any such proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law and (vi) agrees that service of process upon such Subject Party in any such proceeding shall be effective if notice is given in accordance with Section 10.1. Nothing in this Agreement will affect the right of any Subject Party to serve process in any other manner permitted by Law. EACH SUBJECT PARTY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

SECTION 10.5 Severability. This Agreement shall be interpreted in such manner as to be effective and valid under applicable Law. If at any time subsequent to the date hereof, any provision of this Agreement is determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of Law or public policy in any respect, such provision will be enforced to the maximum extent possible given the intent of the Parties and the remaining provisions hereof shall remain in full force and effect.

SECTION 10.6 Fees and Expenses. The Requesting Parties shall pay all out-of-pocket fees and expenses (including attorneys’ fees) reasonably incurred and paid by the Company in connection with: (i) the negotiation, preparation and execution of this Agreement, the SNH Consent and the Lender Consent; (ii) the preparation of a Solicitation/ Recommendation Statement on Schedule 14D-9 and any other required filing with the SEC related to the Tender Offer, this Agreement, the SNH Consent or the Lender Consent; and (iii) the obtaining of (or the failure to obtain) any of the consents described in Section 3.6, in each case, whether or not the Proposed Acquisition is consummated. Except as provided in the preceding sentence, all expenses incurred by the Parties shall be borne solely and entirely by the Party that has incurred the same.

SECTION 10.7 Counterparts. This Agreement may be executed in any number of counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to the other Party (including via facsimile or other electronic transmission), it being understood that each Party need not sign the same counterpart.

SECTION 10.8 Effectiveness of this Agreement. The Requesting Parties may elect, by written notice to the Company, to terminate this Agreement (other than Section 5.1, Section 5.3 and this Article X) at any time after the expiration or termination of the Tender Offer if, at such time, the Requesting Parties and their Controlled Affiliates Beneficially Own less than ten percent (10%) of the then issued and outstanding Common Shares. Upon the termination of this Agreement by the Requesting Parties pursuant to this Section 10.8, (a) the approval previously granted under Section 3-601(j)(3) of the MGCL and Section 9.3 of Article IX of the Company’s Bylaws and the exception to the Ownership Limit previously granted by the Board of Directors of the Company pursuant to this Agreement shall continue to apply in respect of acquisitions of Common Shares made, and Common Shares Beneficially Owned, prior to such termination but, without further approval of the Board of Directors of the Company, shall not apply in respect of any acquisition of Common Shares made after such termination, (b) Section 5.1, Section 5.3 and this Article X shall remain in full force and effect, and (c) except as provided in this Section 10.8, this Agreement (other than Section 5.1, Section 5.3 and this Article X) shall become void and have no effect, without any further liability or obligation on the part of any Party; provided, however, that each Party shall remain liable for its willful breach of this Agreement prior to such termination and such termination shall be without prejudice to the rights and remedies of any other Party with respect to such willful breach.

SECTION 10.9 Waivers and Amendments. This Agreement may be amended, modified, superseded, cancelled, renewed or extended, and the terms and conditions of this Agreement may be waived, only by a written instrument signed by the Parties or, in the case of a waiver, by the Party waiving compliance. No delay on the part of any Party in exercising any right, power or privilege pursuant to this Agreement shall operate as a waiver thereof, nor shall any waiver of the part of any Party of any right, power or privilege pursuant to this Agreement, nor shall any single or partial exercise of any right, power or privilege pursuant to this Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or privilege pursuant to this Agreement. The rights and remedies provided pursuant to this Agreement are cumulative and are not exclusive of any rights or remedies which any Party otherwise may have at Law or in equity.
