(v) Notwithstanding anything to the contrary in this Section 2.1(a), PVF shall have the right to require the Company to include all or part of its Registrable Securities in the registration statement filed in connection with the IPO. PVF may make the request referred to in this Section 2.1(a)(v) at any time prior to such registration statement being declared effective by the SEC by providing written notice of such request to the Company, which notice shall include the number of Registrable Securities to be included in such Registration Statement. Any such request made pursuant to this Section 2.1(a)(v) shall be treated in the same manner as a Demand Registration made hereunder, and PVF shall be entitled to all the benefits and protections of this Agreement, including but not limited to, Section 2.9 hereof, in connection with the registration of its Registrable Securities in the IPO pursuant to this Section 2.1(a)(v).

(b) Notwithstanding anything to the contrary in Section 2.1(a), the Demand Registration rights granted in Section 2.1(a) are subject to the following limitations: (i) the Company shall not be required to cause a registration pursuant to Section 2.1(a)(i) to be declared effective within a period of one hundred and eighty (180) days after the effective date of any other registration statement of the Company filed pursuant to the Securities Act; (ii) the Company shall not be required to effect more than six (6) Demand Registrations for PVF; and (iii) if the Board, in its good faith judgment, determines that any registration of Registrable Securities should not be made or continued because it would materially interfere with any material financing, acquisition, corporate reorganization or merger or other transaction or event involving the Company or any of its subsidiaries (a “Valid Business Reason”), then (x) the Company may postpone filing a registration statement relating to a Demand Registration Request until five (5) Business Days after such Valid Business Reason no longer exists, but in no event for more than three (3) months after the date the Board determines a Valid Business Reason exists and (y) in case a registration statement has been filed relating to a Demand Registration Request, if the Valid Business Reason has not resulted from actions taken by the Company, the Company may cause such registration statement to be withdrawn and its effectiveness terminated or may postpone amending or supplementing such registration statement until five (5) Business Days after such Valid Business Reason no longer exists, but in no event for more than three (3) months after the date the Board determines a Valid Business Reason exists (such period of postponement or withdrawal under this clause (iii), the “Postponement Period”); and the Company shall give written notice of its determination to postpone or withdraw a registration statement and of the fact that the Valid Business Reason for such postponement or withdrawal no longer exists, in each case, promptly after the occurrence thereof; provided, however, the Company shall not be permitted to postpone or withdraw a registration statement after the expiration of any Postponement Period until nine (9) months after the expiration of such Postponement Period.

If the Company shall give any notice of postponement or withdrawal of any registration statement pursuant to clause (iii) above, the Company shall not, during the period of postponement or withdrawal, register any Common Equity, other than pursuant to a registration

statement on Form S-4 or S-8 (or an equivalent registration form then in effect). Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company that the Company has determined to withdraw any registration statement pursuant to clause (iii) above, such Holder will discontinue its disposition of Registrable Securities pursuant to such registration statement and, if so directed by the Company, will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the prospectus covering such Registrable Securities that was in effect at the time of receipt of such notice. If the Company shall have withdrawn or prematurely terminated a registration statement filed under Section 2.1(a)(i) (whether pursuant to clause (iii) above or as a result of any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court), the Company shall not be considered to have effected an effective registration for the purposes of this Agreement until the Company shall have filed a new registration statement covering the Registrable Securities covered by the withdrawn registration statement and such registration statement shall have been declared effective and shall not have been withdrawn. If the Company shall give any notice of withdrawal or postponement of a registration statement, the Company shall, not later than five (5) Business Days after the Valid Business Reason that caused such withdrawal or postponement no longer exists (but in no event later than three (3) months after the date of the postponement or withdrawal), use its reasonable best efforts to effect the registration under the Securities Act of the Registrable Securities covered by the withdrawn or postponed registration statement in accordance with this Section 2.1 (unless the Initiating Holder shall have withdrawn such request, in which case the Company shall not be considered to have effected an effective registration for the purposes of this Agreement), and such registration shall not be withdrawn or postponed pursuant to clause (iii) of Section 2.1(b) above.

(c) In connection with any Demand Registration, the Company shall have the right to designate the lead managing underwriter (any lead managing underwriter for the purposes of this Agreement, the “Manager”) in connection with such registration and each other managing underwriter for such registration; provided that in each case, each such underwriter is reasonably satisfactory to PVF.

(a) If, at any time after the IPO, the Company proposes or is required (pursuant to Section 2.1 or otherwise) to register any of its equity securities under the Securities Act (other than pursuant to registrations on Form S-4 or Form S-8 or any similar successor forms thereto), the Company shall give prompt written notice (in any event within five (5) Business Days after receipt of notice of any exercise of demand registration rights by any Person) of its intention to do so to each of the Holders of record of Registrable Securities. Upon the written request of any such Holder, made within twenty (20) days following the receipt of any such written notice (or fifteen (15) days if the Company states that such registration will be on a Form S-3) (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder and the intended method of distribution thereof), the Company shall, subject to Sections 2.2(c), 2.3 and 2.6 hereof, use its reasonable best efforts to cause all such Registrable Securities, the Holders of which have so requested the registration thereof, to be registered under the Securities Act with the securities which the Company at the time proposes to register to permit the sale or other disposition by the Holders (in accordance with the intended method of

distribution thereof, which may include a Partner Distribution) of the Registrable Securities to be so registered, including, if necessary, by filing with the SEC a post-effective amendment or a supplement to the registration statement filed by the Company or the prospectus related thereto pursuant to a Form 8-K. There is no limitation on the number of such piggyback registrations pursuant to the preceding sentence which the Company is obligated to effect. No registration of Registrable Securities effected under this Section 2.2(a) shall relieve the Company of its obligations to effect Demand Registrations under Section 2.1 hereof.

(b) The Company, subject to Sections 2.3 and 2.6, may elect to include in any registration statement and offering pursuant to demand registration rights by any Person, (i) authorized but unissued shares of Common Equity or shares of Common Equity held by the Company as treasury shares and (ii) any other shares of Common Equity which are requested to be included in such registration pursuant to the exercise of piggyback registration rights granted by the Company after the date hereof and which are not inconsistent with the rights granted in, or otherwise conflict with the terms of, this Agreement (“Additional Piggyback Rights”); provided, however, that such inclusion shall be permitted only to the extent that it is pursuant to, and subject to, the terms of the underwriting agreement or arrangements, if any, entered into by the Initiating Holder.

(c) If, at any time after giving written notice of its intention to register any equity securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such equity securities, the Company may, at its election, give written notice of such determination to all Holders of record of Registrable Securities and (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such abandoned registration, without prejudice, however, to the rights of Holders under Section 2.1, and (ii) in the case of a determination to delay such registration of its equity securities, shall be permitted to delay the registration of such Registrable Securities for the same period as the delay in registering such other equity securities.

(d) Any Holder shall have the right to withdraw its request for inclusion of its Registrable Securities in any registration statement pursuant to this Section 2.2 by giving written notice to the Company of its request to withdraw; provided, however, that (i) such request must be made in writing prior to the earlier of the execution of the underwriting agreement or the execution of the custody agreement with respect to such registration and (ii) such withdrawal shall be irrevocable and, after making such withdrawal, a Holder shall no longer have any right to include Registrable Securities in the registration as to which such withdrawal was made.

(e) Notwithstanding anything contained herein to the contrary, the Company shall, at the request of any Holder (including to effect a Partner Distribution), file any prospectus supplement or post-effective amendments and otherwise take any action necessary to include therein all disclosure and language deemed necessary or advisable by such Holder if such disclosure or language was not included in the initial registration statement, or revise such disclosure or language if deemed necessary or advisable by such Holder.

(a) If any requested registration made pursuant to Section 2.1 involves an underwritten offering and the Manager of such offering shall advise the Company that, in its view, the number of securities requested to be included in such registration by the Holders of Registrable Securities, the Company or any other Persons exercising Additional Piggyback Rights exceeds the largest number (the “Section 2.3(a) Sale Number”) that can be sold in an orderly manner in such registration within a price range acceptable to the Majority Participating Holders, the Company shall use its reasonable best efforts to include in such registration:

(i) first, all Registrable Securities requested to be included in such registration by the Holders thereof (including pursuant to the exercise of piggyback rights pursuant to Section 2.2); provided, however, that if the number of such Registrable Securities exceeds the Section 2.3(a) Sale Number, the number of such Registrable Securities (not to exceed the Section 2.3(a) Sale Number) to be included in such registration shall be allocated on a pro rata basis among all Holders requesting that Registrable Securities be included in such registration, based on the number of Registrable Securities then owned by each such Holder requesting inclusion in relation to the number of Registrable Securities owned by all Holders requesting inclusion;

(ii) second, to the extent that the number of Registrable Securities to be included pursuant to clause (i) of this Section 2.3(a) is less than the Section 2.3(a) Sale Number, any securities that the Company proposes to register, up to the Section 2.3(a) Sale Number; and

Notwithstanding anything in this Section 2.3(a) to the contrary, no employee shareholder of the Company will be entitled to include Registrable Securities in a registration requested by PVF pursuant to Section 2.1 to the extent the Manager of such offering shall determine in good faith that the participation of such employee shareholder would adversely affect the marketability of the securities being sold by the Initiating Holder in such registration.

(b) If any registration made pursuant to Section 2.2 involves an underwritten primary offering on behalf of the Company after the date hereof and the Manager (as selected by the Company) shall advise the Company that, in its view, the number of securities requested to be included in such registration exceeds the number (the “Section 2.3(b) Sale Number”) that can be sold in an orderly manner in such registration within a price range acceptable to the Company, the Company shall include in such registration:

(i) first, all equity securities that the Company proposes to register for its own account;

(ii) second, to the extent that the number of Registrable Securities to be included pursuant to clause (i) of this Section 2.3(b) is less than the Section 2.3(b) Sale Number, the remaining Registrable Securities to be included in such registration shall be allocated on a pro rata basis among all Holders requesting that Registrable Securities be included in such registration pursuant to the exercise of piggyback rights pursuant to Section 2.2, based on the aggregate number of Registrable Securities then owned by each such Holder requesting inclusion in relation to the aggregate number of Registrable Securities owned by all Holders requesting inclusion, up to the Section 2.3(b) Sale Number; and

(iii) third, to the extent that the number of Registrable Securities to be included pursuant to clauses (i) and (ii) of this Section 2.3(b) is less than the Section 2.3(b) Sale Number, the remaining Registrable Securities to be included in such registration shall be allocated on a pro rata basis among all Persons requesting that securities be included in such registration pursuant to the exercise of Additional Piggyback Rights, based on the aggregate number of Piggyback Shares then owned by each Person requesting inclusion in relation to the aggregate number of Piggyback Shares owned by all Persons requesting inclusion, up to the Section 2.3(b) Sale Number.

(c) If any registration pursuant to Section 2.2 involves an underwritten offering that was initially requested by any Person(s) other than a Holder to whom the Company has granted registration rights which are not inconsistent with the rights granted in, or otherwise conflict with the terms of, this Agreement and the Manager (as selected by the Company or such other Person) shall advise the Company that, in its view, the number of securities requested to be included in such registration exceeds the number (the “Section 2.3(c) Sale Number”) that can be sold in an orderly manner in such registration within a price range acceptable to the Company, the Company shall include in such registration:

(i) first, the shares requested to be included in such registration shall be allocated on a pro rata basis among such Person(s) requesting the registration and all Holders requesting that Registrable Securities be included in such registration pursuant to the exercise of piggyback rights pursuant to Section 2.2, based on the aggregate number of securities or Registrable Securities, as applicable, then owned by each of the foregoing requesting inclusion in relation to the aggregate number of securities or Registrable Securities, as applicable, owned by all such Holders and Persons requesting inclusion, up to the Section 2.3(c) Sale Number;

(k) deliver promptly to counsel for each Participating Holder and to each managing underwriter, if any, copies of all correspondence between the SEC and the Company, its counsel or auditors and all memoranda relating to discussions with the SEC or its staff with respect to the registration statement, and, upon receipt of such confidentiality agreements as the Company may reasonably request, make reasonably available for inspection by counsel for each Participating Holder, by counsel for any underwriter, participating in any disposition to be effected pursuant to such registration statement and by any accountant or other agent retained by any Participating Holder or any such underwriter, all pertinent financial and other records, pertinent corporate documents and properties of the Company, and cause all of the Company’s officers, directors and employees to supply all information reasonably requested by any such counsel for a Participating Holder, counsel for an underwriter, accountant or agent in connection with such registration statement;

(l) use its reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness of the registration statement, or the prompt lifting of any suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction;

(m) provide a CUSIP number for all Registrable Securities, not later than the effective date of the registration statement;

(n) use its reasonable best efforts to make available its employees and personnel for participation in “road shows” and other marketing efforts and otherwise provide reasonable assistance to the underwriters (taking into account the needs of the Company’s businesses and the requirements of the marketing process) in marketing the Registrable Securities in any underwritten offering;

(o) prior to the filing of any document which is to be incorporated by reference into the registration statement or the prospectus (after the initial filing of such registration statement), and prior to the filing of any free writing prospectus, provide copies of such document to counsel for each Participating Holder and to each managing underwriter, if any, and make the Company’s representatives reasonably available for discussion of such document and make such changes in such document concerning the Participating Holders prior to the filing thereof as counsel for the Participating Holders or underwriters may reasonably request;

(p) furnish to counsel for each Participating Holder and to each managing underwriter, without charge, at least one signed copy of the registration statement and any post-effective amendments or supplements thereto, including financial statements and schedules, all documents incorporated therein by reference, the prospectus contained in such registration statement (including each preliminary prospectus and any summary prospectus), any other prospectus filed under Rule 424 under the Securities Act and all exhibits (including those incorporated by reference) and any free writing prospectus utilized in connection therewith;

(q) cooperate with the Participating Holders and the managing underwriter, if any, to facilitate the timely preparation and delivery of certificates not bearing any restrictive legends representing the Registrable Securities to be sold, and cause such Registrable Securities to be issued in such denominations and registered in such names in accordance with the underwriting agreement at least three (3) Business Days prior to any sale of Registrable Securities to the underwriters or, if not an underwritten offering, in accordance with the instructions of the Participating Holders at least three (3) Business Days prior to any sale of Registrable Securities and instruct any transfer agent and registrar of Registrable Securities to release any stop transfer orders in respect thereof;

(r) take no direct or indirect action prohibited by Regulation M under the Exchange Act; provided, however, that to the extent that any prohibition is applicable to the Company, the Company will take such action as is necessary and feasible to make any such prohibition inapplicable;

(s) use its reasonable best efforts to cause the Registrable Securities covered by the applicable registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the Participating Holders or the underwriters, if any, to consummate the disposition of such Registrable Securities;

(t) take all such other commercially reasonable actions as are necessary or advisable in order to expedite or facilitate the disposition of such Registrable Securities;

(u) take all reasonable action to ensure that any free writing prospectus utilized in connection with any registration covered by Section 2.1 or 2.2 complies in all material respects with the Securities Act, is filed in accordance with the Securities Act to the extent required thereby, is retained in accordance with the Securities Act to the extent required thereby and, when taken together with the related prospectus, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and

(v) in connection with any underwritten offering, if at any time the information conveyed to a purchaser at the time of sale includes any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, promptly file with the SEC such amendments or supplements to such information as may be necessary so that the statements as so amended or supplemented will not, in light of the circumstances, be misleading.

To the extent the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) (a “WKSI”) at the time any Demand Registration Request is submitted to the Company, and such Demand Registration Request requests that the Company file an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “automatic shelf registration statement”) on Form S-3, the Company shall file an automatic shelf registration statement which covers those Registrable Securities which are requested to be registered. The Company shall use its commercially reasonable best efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such automatic shelf registration statement is required to remain effective. If the Company does not pay the filing fee covering the Registrable Securities at the time the automatic shelf registration statement is filed, the Company agrees to pay such fee at such time or times as the Registrable Securities are to be sold. If the automatic shelf registration statement has been outstanding for at least three (3) years, at the end of the third year the Company shall refile a new automatic shelf registration statement covering the Registrable Securities. If at any time when the Company is required to re-evaluate its WKSI status the Company determines that it is not a WKSI, the Company shall use its commercially reasonable best efforts to refile the shelf registration statement on Form S-3 and, if such form is not available, Form S-1 and keep such registration statement effective during the period during which such registration statement is required to be kept effective.

If the Company files any shelf registration statement for the benefit of the holders of any of its securities other than the Holders, the Company agrees that it shall include in such registration statement such disclosures as may be required by Rule 430B under the Securities Act (referring to the unnamed selling security holders in a generic manner by identifying the initial offering of the securities to the Holders) in order to ensure that the Holders may be added to such shelf registration statement at a later time through the filing of a prospectus supplement rather than a post-effective amendment.

The Company may require as a condition precedent to the Company’s obligations under this Section 2.4 that each Participating Holder as to which any registration is being effected furnish the Company such information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request provided that such information is necessary for the Company to consummate such registration and shall be used only in connection with such registration.

Each Holder of Registrable Securities agrees that upon receipt of any notice from the Company of the happening of any event of the kind described in clause (v) of paragraph (e) of this Section 2.4, such Holder will discontinue such Holder’s disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by paragraph (e) of this Section 2.4 and, if so directed by the Company, will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the prospectus covering such Registrable Securities that was in effect at the time of receipt of such notice. In the event the Company shall give any such notice, the applicable

period mentioned in paragraph (b) of this Section 2.4 shall be extended by the number of days during such period from and including the date of the giving of such notice to and including the date when each Participating Holder covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by paragraph (e) of this Section 2.4.

If any such registration statement or comparable statement under state “blue sky” laws refers to any Holder by name or otherwise as the Holder of any securities of the Company, then such Holder shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to such Holder and the Company, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the Company’s securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to such Holder by name or otherwise is not in the judgment of the Company, as advised by counsel, required by the Securities Act or any similar federal statute or any state “blue sky” or securities law then in force, the deletion of the reference to such Holder.

(a) The Company shall pay all Expenses with respect to any registration of Registrable Securities pursuant to this Article 2, whether or not a registration statement becomes effective.

(b) Notwithstanding the foregoing, (x) the provisions of this Section 2.5 shall be deemed amended to the extent necessary to cause these expense provisions to comply with state “blue sky” laws of each state in which the offering is made and (y) in connection with any registration hereunder, each Participating Holder shall pay all underwriting discounts and commissions and any transfer taxes, if any, attributable to the sale of such Registrable Securities, pro rata with respect to payments of discounts and commissions in accordance with the number of shares sold in the offering by such Participating Holder.

2.6. Certain Limitations on Registration Rights. In the case of any registration under Section 2.1 pursuant to an underwritten offering, or, in the case of a registration under Section 2.2, if the Company has determined to enter into an underwriting agreement in connection therewith, all securities to be included in such registration shall be subject to such underwriting agreement and no Person may participate in such registration unless such Person (i) agrees to sell such Person’s securities on the basis provided therein and completes and executes all reasonable questionnaires, and other documents (including custody agreements and powers of attorney) which must be executed in connection therewith; provided, however, that all such documents shall be consistent with the provisions hereof and (ii) provides such other information to the Company or the underwriter as may be necessary to register such Person’s securities.

(a) Each Holder agrees, (i) to the extent requested in writing by a managing underwriter, if any, of any registration effected pursuant to Section 2.1, not to sell, transfer or

otherwise dispose of, including any sale pursuant to Rule 144 under the Securities Act, any Common Equity, or any other equity security of the Company or any security convertible into or exchangeable or exercisable for any equity security of the Company (other than as part of such underwritten public offering) during the time period reasonably requested by the managing underwriter, not to exceed ninety (90) days plus an extension period, which shall be no longer than 17 days, as may be reasonably requested by the managing underwriter to address FINRA regulations regarding the publishing of research, or such shorter period as the Company or any executive officer or director of the Company shall agree to (and the Company hereby also so agrees (except that the Company may effect any sale or distribution of any such securities pursuant to a registration on Form S-4 (if reasonably acceptable to such managing underwriter) or Form S-8, or any successor or similar form which is (x) then in effect or (y) shall become effective upon the conversion, exchange or exercise of any then outstanding Common Equity Equivalent), to use its reasonable best efforts to cause each holder of any equity security or any security convertible into or exchangeable or exercisable for any equity security of the Company purchased from the Company at any time other than in a public offering so to agree), and (ii) to the extent requested in writing by a managing underwriter of any underwritten public offering effected by the Company for its own account, not to sell any Common Equity (other than as part of such underwritten public offering) during the time period reasonably requested by the managing underwriter, which period shall not exceed ninety (90) days plus an extension period, which shall be no longer than 17 days, as may be reasonably requested by the managing underwriter to address FINRA regulations regarding the publishing of research, or such shorter period as the Company or any executive officer or director of the Company shall agree to.

(b) The Company hereby agrees that, if it shall previously have received a request for registration pursuant to Section 2.1 or 2.2, and if such previous registration shall not have been withdrawn or abandoned, the Company shall not sell, transfer, or otherwise dispose of, any Common Equity, or any other equity security of the Company or any security convertible into or exchangeable or exercisable for any equity security of the Company (other than as part of such underwritten public offering, a registration on Form S-4 or Form S-8 or any successor or similar form which is (x) then in effect or (y) shall become effective upon the conversion, exchange or exercise of any then outstanding Common Equity Equivalent), until a period of ninety (90) days plus an extension period, which shall be no longer than 17 days, as may be reasonably requested by the managing underwriter to address FINRA regulations regarding the publishing of research, shall have elapsed from the effective date of such previous registration; and the Company shall (i) so provide in any registration rights agreements hereafter entered into with respect to any of its securities and (ii) use its reasonable best efforts to cause each holder of any equity security or any security convertible into or exchangeable or exercisable for any equity security of the Company purchased from the Company at any time other than in a public offering to so agree.

2.8. No Required Sale. Nothing in this Agreement shall be deemed to create an independent obligation on the part of any Holder to sell any Registrable Securities pursuant to any effective registration statement.

(a) In the event of any registration of any securities of the Company under the Securities Act pursuant to this Article 2, the Company will, and hereby agrees to, and hereby

does, indemnify and hold harmless, to the fullest extent permitted by law, each Participating Holder, its directors, officers, fiduciaries, employees, stockholders, members or general and limited partners (and the directors, officers, fiduciaries, employees, stockholders, members or general and limited partners thereof), each other Person who participates as a seller (and its directors, officers, fiduciaries, employees, stockholders, members or general and limited partners), underwriter or Qualified Independent Underwriter, if any, in the offering or sale of such securities, each officer, director, employee, stockholder, fiduciary, managing director, agent, affiliate, consultant, representative, successor, assign or partner of such underwriter or Qualified Independent Underwriter, and each other Person, if any, who controls such seller or any such underwriter or Qualified Independent Underwriter within the meaning of the Securities Act, from and against any and all losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) and expenses (including reasonable fees of counsel and any amounts paid in any settlement effected with the Company’s consent, which consent shall not be unreasonably withheld or delayed) to which each such indemnified party may become subject under the Securities Act or otherwise in respect thereof (collectively, “Claims”), insofar as such Claims arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any registration statement under which such securities were registered under the Securities Act or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary, final or summary prospectus or any amendment or supplement thereto, together with the documents incorporated by reference therein, or any free writing prospectus utilized in connection therewith, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) any untrue statement or alleged untrue statement of a material fact in the information conveyed by the Company to any purchaser at the time of the sale to such purchaser, or the omission or alleged omission to state therein a material fact required to be stated therein, or (iv) any violation by the Company of any federal, state or common law rule or regulation applicable to the Company and relating to action required of or inaction by the Company in connection with any such registration, and the Company will reimburse any such indemnified party for any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim as such expenses are incurred; provided, however, that the Company shall not be liable to any such indemnified party in any such case to the extent such Claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact made in such registration statement or amendment thereof or supplement thereto or in any such prospectus or any preliminary, final or summary prospectus or free writing prospectus in reliance upon and in conformity with written information furnished to the Company by or on behalf of such indemnified party specifically for use therein. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of such securities by such seller.

(b) Each Participating Holder (and, if the Company requires as a condition to including any Registrable Securities in any registration statement filed in accordance with Section 2.1 or 2.2, any underwriter and Qualified Independent Underwriter, if any) shall, severally and not jointly, indemnify and hold harmless (in the same manner and to the same

extent as set forth in paragraph (a) of this Section 2.9) to the extent permitted by law the Company, its officers and directors, each Person controlling the Company within the meaning of the Securities Act and all other prospective sellers and their directors, officers, stockholders, fiduciaries, managing directors, agents, affiliates, consultants, representatives, successors, assigns or general and limited partners and respective controlling Persons with respect to any untrue statement or alleged untrue statement of any material fact in, or omission or alleged omission of any material fact from, such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, or any free writing prospectus utilized in connection therewith, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company or its representatives by or on behalf of such Participating Holder or underwriter or Qualified Independent Underwriter, if any, specifically for use therein and reimburse such indemnified party for any legal or other expenses reasonably incurred in connection with investigating or defending any such Claim as such expenses are incurred; provided, however, that the aggregate amount which any such Participating Holder shall be required to pay pursuant to this Section 2.9(b) and Sections 2.9(c) and (e) shall in no case be greater than the amount of the net proceeds received by such Participating Holder upon the sale of the Registrable Securities pursuant to the registration statement giving rise to such Claim. The Company and each Participating Holder hereby acknowledge and agree that, unless otherwise expressly agreed to in writing by such Participating Holders to the contrary, for all purposes of this Agreement, the only information furnished or to be furnished to the Company for use in any such registration statement, preliminary, final or summary prospectus or amendment or supplement thereto or any free writing prospectus are statements specifically relating to (a) the beneficial ownership of shares of Common Equity by such Participating Holder and its Affiliates and (b) the name and address of such Participating Holder. If any additional information about such Holder or the plan of distribution (other than for an underwritten offering) is required by law to be disclosed in any such document, then such Holder shall not unreasonably withhold its agreement referred to in the immediately preceding sentence. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of such securities by such Holder.

(c) Indemnification similar to that specified in the preceding paragraphs (a) and (b) of this Section 2.9 (with appropriate modifications) shall be given by the Company and each Participating Holder with respect to any required registration or other qualification of securities under any applicable securities and state “blue sky” laws.

(d) Any Person entitled to indemnification under this Agreement shall notify promptly the indemnifying party in writing of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 2.9, but the failure of any indemnified party to provide such notice shall not relieve the indemnifying party of its obligations under the preceding paragraphs of this Section 2.9, except to the extent the indemnifying party is materially and actually prejudiced thereby and shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than under this Article 2. In case any action or proceeding is brought against an indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, unless in the reasonable opinion of outside counsel to

the indemnified party a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, to assume the defense thereof jointly with any other indemnifying party similarly notified, to the extent that it chooses, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party that it so chooses, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that (i) if the indemnifying party fails to take reasonable steps necessary to defend diligently the action or proceeding within twenty (20) days after receiving notice from such indemnified party that the indemnified party believes it has failed to do so; or (ii) if such indemnified party who is a defendant in any action or proceeding which is also brought against the indemnifying party reasonably shall have concluded that there may be one or more legal or equitable defenses available to such indemnified party which are not available to the indemnifying party or which may conflict with those available to another indemnified party with respect to such Claim; or (iii) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, then, in any such case, the indemnified party shall have the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all indemnified parties in each jurisdiction, except to the extent any indemnified party or parties reasonably shall have made a conclusion described in clause (ii) or (iii) above) and the indemnifying party shall be liable for any expenses therefor. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e) If for any reason the foregoing indemnity is unavailable, unenforceable or is insufficient to hold harmless an indemnified party under Sections 2.9(a), (b) or (c), then each applicable indemnifying party shall contribute to the amount paid or payable to such indemnified party as a result of any Claim in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, with respect to such Claim. The relative fault shall be determined by reference to, among other things, whether the untrue 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 the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. If, however, the allocation provided in the second preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative faults but also the relative benefits of the indemnifying party and the indemnified party as well as any other relevant equitable considerations. The parties hereto agree that it would not be just and equitable if any contribution pursuant to this Section 2.9(e) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the preceding sentences of this Section 2.9(e). The amount paid or payable in

respect of any Claim shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. Notwithstanding anything in this Section 2.9(e) to the contrary, no indemnifying party (other than the Company) shall be required pursuant to this Section 2.9(e) to contribute any amount greater than the amount of the net proceeds received by such indemnifying party upon the sale of the Registrable Securities pursuant to the registration statement giving rise to such Claim, less the amount of any indemnification payment made by such indemnifying party pursuant to Sections 2.9(b) and (c).

(f) The indemnity and contribution agreements contained herein shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made or omitted by or on behalf of any indemnified party and shall survive the transfer of the Registrable Securities by any such party.

(g) The indemnification and contribution required by this Section 2.9 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, loss, damage or liability is incurred; provided, however, that the recipient thereof hereby undertakes to repay such payments if and to the extent it shall be determined by a court of competent jurisdiction that such recipient is not entitled to such payment hereunder.

3.1. Requested Underwritten Offerings. If requested by the underwriters for any underwritten offering pursuant to a registration requested under Section 2.1, the Company shall enter into a customary underwriting agreement with the underwriters. Such underwriting agreement shall (i) be satisfactory in form and substance to the Majority Participating Holders, (ii) contain terms not inconsistent with the provisions of this Agreement and (iii) contain such representations and warranties by, and such other agreements on the part of, the Company and such other terms as are generally prevailing in agreements of that type, including, without limitation, indemnities and contribution agreements on substantially the same terms as those contained herein. Any Participating Holder shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such Participating Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Participating Holder; provided, however, that the Company shall not be required to make any representations or warranties with respect to written information specifically provided by a Participating Holder for inclusion in the registration statement. Each such Participating Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Participating Holder, its ownership of and title to the Registrable Securities, any written information specifically provided by such Participating Holder for inclusion in the registration statement and its intended method of distribution; and any

liability of such Participating Holder to any underwriter or other Person under such underwriting agreement shall be limited to liability arising from breach of its representations and warranties and shall in no case be greater than the amount of the net proceeds received by such Holder upon the sale of the Registrable Securities pursuant to the registration statement.

3.2. Piggyback Underwritten Offerings. In the case of a registration pursuant to Section 2.2, if the Company shall have determined to enter into an underwriting agreement in connection therewith, all of the Participating Holders’ Registrable Securities to be included in such registration shall be subject to such underwriting agreement. Any Participating Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such Participating Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Participating Holder; provided, however, that the Company shall not be required to make any representations or warranties with respect to written information specifically provided by a Participating Holder for inclusion in the registration statement. Each such Participating Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Participating Holder, its ownership of and title to the Registrable Securities, any written information specifically provided by such Participating Holder for inclusion in the registration statement and its intended method of distribution; and any liability of such Participating Holder to any underwriter or other Person under such underwriting agreement shall be limited to liability arising from breach of its representations and warranties and shall in no case be greater than the amount of the net proceeds received by such Participating Holder upon the sale of the Registrable Securities pursuant to the registration statement.

4.1. Term. This Agreement shall continue in effect until the earlier of (a) the date on which no Registrable Securities remain outstanding and (b) the PVF Distribution Date.

4.2. Adjustments Affecting Registrable Securities. The Company agrees that it shall not effect or permit to occur any combination or subdivision of shares of Common Equity which would adversely affect the ability of any Holder of any Registrable Securities to include such Registrable Securities in any registration contemplated by this Agreement or the marketability of such Registrable Securities in any such registration. The Company agrees that it will take all reasonable steps necessary to effect a subdivision of shares of Common Equity if in the reasonable judgment of (a) PVF or (b) the managing underwriter for the offering in respect of such Demand Registration Request, such subdivision would enhance the marketability of the Registrable Securities. Each Holder agrees to vote all of its shares of capital stock in a manner, and to take all other actions necessary, to permit the Company to carry out the intent of the preceding sentence including, without limitation, voting in favor of an amendment to the Company’s organizational documents in order to increase the number of authorized shares of capital stock of the Company. In any event, the provisions of this Agreement shall apply, to the full extent set forth herein with respect to the Registrable Securities, to any and all shares of capital stock of the Company or any successor or assign of the Company (whether by merger, share exchange, consolidation, sale of assets or otherwise) which may be issued in respect of, in

exchange for or in substitution of, Registrable Securities and shall be appropriately adjusted for any stock dividends, splits, reverse splits, combinations, recapitalizations and the like occurring after the date hereof.

4.3. Rule 144 and Rule 144A. If the Company shall have filed a registration statement pursuant to the requirements of Section 12 of the Exchange Act or a registration statement pursuant to the requirements of the Securities Act in respect of the Common Equity or Common Equity Equivalents, the Company covenants that (i) so long as it remains subject to the reporting provisions of the Exchange Act, it will timely file the reports required to be filed by it under the Securities Act or the Exchange Act (including, but not limited to, the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 under the Securities Act, as such Rule may be amended (“Rule 144”)) or, if the Company is not required to file such reports, it will, upon the request of any Holder, make publicly available other information so long as necessary to permit sales by such Holder under Rule 144, Rule 144A under the Securities Act, as such Rule may be amended (“Rule 144A”), or any similar rules or regulations hereafter adopted by the SEC, and (ii) it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144, (B) Rule 144A or (C) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements.

4.4. Nominees for Beneficial Owners. If Registrable Securities are held by a nominee for the beneficial owner thereof, the beneficial owner thereof may, at its option, be treated as the Holder of such Registrable Securities for purposes of any request or other action by any Holder or Holders of Registrable Securities pursuant to this Agreement (or any determination of any number or percentage of shares constituting Registrable Securities held by any Holder or Holders of Registrable Securities contemplated by this Agreement), provided that the Company shall have received assurances reasonably satisfactory to it of such beneficial ownership.

4.5. Amendments and Waivers. Any provisions of this Agreement may be amended, modified, supplemented or waived with the written approval of the Company and Holders holding a majority of the Registrable Securities then held by all Holders (which majority must include PVF, so long as PVF holds any Registrable Securities). No waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any other provision hereof (whether or not similar). No failure or delay on the part of any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof or of any other or future exercise of any such right, power or privilege.

4.6. Notices. Any notice, request, instruction or other document to be given hereunder by any party to the others shall be in writing and delivered personally or sent by registered or certified mail, postage prepaid, or by facsimile to the Company or to PVF at the address set forth below and to any subsequent holder of Units subject to this Agreement at such address as indicated by the Company’s records, or at such address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party. Any notice, request, instruction or other document given as provided above shall be deemed given to the receiving
