Notwithstanding the foregoing, the Purchaser shall not be required to file an amendment or supplement to its Shelf Registration Statement within thirty (30) days of a previous amendment or supplement to the Shelf Registration Statement.

Section 3.4 Piggyback Registration. If the Purchaser proposes to file a registration statement under the Securities Act with respect to an offering of Purchaser Shares, whether or not for sale for its own account and whether or not an underwritten offering or an underwritten registration, then the Purchaser shall give prompt written notice of such filing no later than ten (10) Business Days prior to the filing date (the “Piggyback Notice”) to the Holders. The Piggyback Notice shall offer such Holders the opportunity to include (or cause to be included) in such registration statement the number of Eligible Securities as each such Holder may request (each, a “Piggyback Registration”). If any written requests for inclusion therein (each, a “Piggyback Request”) are delivered to the Purchaser within ten (10) Business Days after notice has been given to the applicable holder, then the Purchaser shall include all Eligible Securities specified in such a Piggyback Request in any such registration statement filed by the Purchaser (it being understood that the Purchaser shall have no obligation to file any such registration statement as a result of the receipt of any Piggyback Request). Notwithstanding the foregoing, if the Purchaser proposes to file such a registration statement prior to the date that is ten (10) Business Days after the date of this Agreement, then the Purchaser shall give the Piggyback Notice as soon as reasonably practicable prior to the filing of such registration statement and the Seller shall coordinate with the Holders to deliver any Piggyback Request as promptly as reasonably practicable and prior to the expected filing date.

(a) If at any time (i) the Purchaser is pursuing a financing, acquisition, disposition, merger, reorganization or similar transaction and determines in good faith that the filing or amendment of a Shelf Registration Statement or offering or sale of Eligible Securities pursuant thereto (or any disclosures required to be made in connection therewith) would materially adversely affect or materially delay its ability to pursue or consummate such transaction, (ii) the Purchaser determines in good faith that the filing or amendment of a Shelf Registration Statement or offering or sale of Eligible Securities pursuant thereto would be reasonably likely to require disclosure of non-public material information that the Purchaser determines in good faith is not in the best interests of the Purchaser and its shareholders or (iii) during a Scheduled Blackout (either (i), (ii) or (iii), a “Blackout”), the Purchaser shall not be required to effect any registration of Eligible Securities and each Selling Holder shall, upon its receipt of written notice of such Blackout from the Purchaser, suspend sales of Eligible Securities pursuant to such registration statement until the earlier of: (x) forty-five (45) days after the Purchaser’s delivery of such written notice to the Selling Holders; and (y) such time as the Purchaser notifies the Selling Holders that the Blackout Period has been terminated.

The number of days from such suspension of offers or sales by the Selling Holders until the day when such offers or sales may be resumed under clause (i) (ii) or (iii) hereof is hereinafter called a “Blackout Period.” In no event (x) may the Purchaser deliver more than one (1) notice of a Blackout Period (other than of any Scheduled Blackout) and (y) may the duration of the Blackout Period exceed sixty (60) days.

(b) Upon receipt of notification of any event contemplated by Sections 4.1(g)(ii), (iii), (iv), (v) or (vi) hereof, the Selling Holders and any underwriters acting in connection with any underwritten offering shall refrain from selling any Eligible Securities pursuant to the Shelf Registration Statement or using a prospectus or any supplement thereto (a “Suspension”) until the Selling Holders and any underwriters acting in connection with any underwritten offering have received copies of a supplemented or amended prospectus prepared and filed by the Purchaser, or until such Selling Holders and underwriters are advised in writing by the Purchaser that the current prospectus or supplement thereto may be used. In the event of any Suspension, subject to Section 4.2(a), the Purchaser will use its reasonable best efforts to cause the availability for use of the Shelf Registration Statement and the prospectus to be resumed as soon as reasonably possible after delivery of the notification contemplated by Sections 4.1(g)(ii), (iii), (iv), (v) and (vi) hereof.

(c) In the event of any Blackout Period or Suspension, the Purchaser may impose stop transfer instructions with respect to the sale or transfer of Eligible Securities by

the Selling Holders and any underwriters acting in connection with any underwritten offering until the end of the applicable Blackout Period or Suspension.

Section 4.3 Qualification for Rule 144 Sales. Until such time as all Eligible Securities have been sold in the manner set forth and as contemplated in the Shelf Registration Statement or, if earlier, such time as no Eligible Securities remain outstanding (including pursuant to clause (ii) of the Eligible Securities definition), the Purchaser shall use its reasonable best efforts to comply with the filing requirements described in Rule 144 (c)(1) so as to enable the Holders to sell Eligible Securities without registration under the Securities Act and, upon the written request of any Holder, the Purchaser shall deliver to such Holder a written statement as to whether it has complied with such filing requirements.

Such Holder of Eligible Securities shall provide such certificates, documents and/or legal opinions as the Purchaser and the Purchaser’s registrar and transfer agent may reasonably request in connection with this Section 4.4.

Section 4.5 Holder Efforts. If and whenever the Purchaser is permitted to elect to consummate an offering of the Eligible Securities pursuant to Article III, each Holder shall use its reasonable best efforts to take any actions as are necessary to effect the sale of the Eligible Securities as contemplated by such election pursuant to this Agreement as promptly as practicable.

(a) In the event of any registration of Eligible Securities hereunder, the Purchaser will indemnify and hold harmless each Selling Holder, its directors, trustees, officers, partners, direct and indirect equityholders and employees and each other Person who participates as an underwriter in the offering or sale of such securities and each other Person, if any, who controls each such Selling Holder or any such underwriter within the meaning of the Securities Act, against any and all losses, claims, damages, expenses or liabilities, joint or several, actions or proceedings (whether commenced or threatened) in respect thereof, to which each such indemnified party may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, expenses or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement contemplated hereby under which Eligible Securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, any issuer Free Writing Prospectus or any “issuer information” (as defined in Rule 433 of the Act) filed or required to be filed pursuant to Rule 433(d) under the Act, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a preliminary prospectus, final prospectus or summary prospectus, in light of the circumstances in which they were made) not misleading, and the Purchaser will reimburse each such Selling Holder and each such director, trustee, officer, partner, or employee, underwriter and controlling person for any out-of-pocket legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, expense, liability, action, or proceeding; provided, however, that the Purchaser shall not be liable in any such case to the extent that any such loss, claim, damage, expense or liability (or action or proceeding in respect thereof) arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary

prospectus, issuer Free Writing Prospectus, “issuer information” (as defined in Rule 433 of the Act), amendment or supplement in reliance upon and in conformity with written information furnished to the Purchaser by or on behalf of any Selling Holder or underwriter expressly for use therein.

(b) Each Selling Holder severally will, and hereby does, indemnify and hold harmless the Purchaser, its directors, officers, employees, and each person who participates as an underwriter in the offering or sale of such securities, and each Person, if any, who controls the Purchaser within the meaning of the Securities Act against any and all losses, claims, damages, expenses or liabilities, joint or several, actions or proceedings (whether commenced or threatened) in respect thereof, to which each such indemnified party may become subject under the Securities Act or otherwise insofar as such losses, claims, damages, expenses or liabilities (or actions or proceedings, whether commenced or threatened in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any registration statement contemplated hereby under which Eligible Securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, any Free Writing Prospectus or any “issuer information” (as defined in Rule 433 of the Act) filed or required to be filed pursuant to Rule 433(d) under the Act, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a preliminary prospectus, final prospectus or summary prospectus, in light of the circumstances in which they were made) not misleading, but only to the extent that such statement or omission was made in reliance upon and, in conformity with, written information furnished by or on behalf of such Selling Holder to the Purchaser expressly for use therein. In no event shall the aggregate amounts payable by any Selling Holder by way of indemnity or contribution under this Article VI exceed the net proceeds from the related offering received by such Selling Holder.

(c) Promptly after receipt by any indemnified party hereunder of notice of the commencement of any action or proceeding involving a claim referred to in paragraphs (a) or (b) of this Section 6.1, the indemnified party will notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve the indemnifying party from any liability which it may have to any indemnified party under paragraphs (a) or (b) of this Section 6.1 (except to the extent that it has been prejudiced by such failure). In case any such action, suit, claim or proceeding is brought against any indemnified party, the indemnifying party shall be entitled to participate therein and, to the extent it may elect by written notice delivered to the indemnified party within thirty (30) days after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party (at its sole cost). Notwithstanding the foregoing, the indemnified party shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such suit, action, claim or proceeding or(ii) the indemnifying party shall have failed to assume the defense of such action, suit, claim or proceeding within a reasonable time after notice of commencement of the action, suit, claim or proceeding or . If any of the events specified in clauses (i) or(ii) of the preceding sentence shall have occurred or shall otherwise be applicable, then the reasonable fees and expenses of one

counsel (plus local counsel as reasonably required) selected by a majority in interest of the indemnified parties shall be borne by the indemnifying party. If, in any case specified in the foregoing clauses (i) or (ii), the indemnified party employs separate counsel(s), the indemnifying party shall not have the right to direct the defense of such action, suit, claim or proceeding on behalf of the indemnified party. Anything in this paragraph to the contrary notwithstanding, an indemnifying party shall not be liable for the settlement of any action, suit, claim or proceeding effected without its prior written consent (which consent in the case of an action, suit, claim or proceeding exclusively seeking monetary relief shall not be unreasonably withheld, delayed or conditioned). No indemnifying party shall, without the written consent of the relevant indemnified party, effect any settlement of any pending or threatened action, suit, claim or proceeding in respect of which such indemnified party is a party and indemnity has been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are or could have been the subject matter of such claim, action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party. Such indemnification shall remain in full force and effect irrespective of any investigation made by or on behalf of an indemnified party.

(d) If for any reason the indemnity under this Section 6.1 is unavailable or is insufficient to hold harmless any indemnified party under paragraphs (a) or (b) of this Section 6.1, then the indemnifying parties shall contribute to the amount paid or payable to the indemnified party as a result of any loss, claim, expense, damage or liability (or actions or proceedings, whether commenced or threatened, in respect thereof), and legal or other expenses reasonably incurred by the indemnified party in connection with investigating or defending any such loss, claim, expense, damage, liability, action or proceeding, 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. 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 Purchaser or the Selling Holder 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 or provides a lesser sum to the indemnified party than the amount herein before calculated, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party in such proportion as is appropriate to reflect not only such relative fault 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 contributions pursuant to this paragraph (d) of Section 6.1 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 paragraph (d) of Section 6.1. Notwithstanding the anything to the contrary in this Agreement, each Holder shall not be required to contribute an amount greater than the net proceeds received by such Holder from the sale of Eligible Securities pursuant to the registration statement to which claims relate.

(e) All legal and other expenses reasonably incurred by or on behalf of any indemnified party in connection with investigating or defending any loss, claim, expense, damage, liability, action or proceeding which are to be borne by the indemnifying party pursuant

to this Section 6.1 shall be paid by the indemnifying party in advance of the final disposition of such investigation, defense, action or proceeding within thirty (30) days after the receipt by the indemnifying party of a statement or statements from the indemnified party requesting from time to time such payment, advance or advances. The entitlement of each indemnified party to such payment or advancement of expenses shall include those incurred in connection with any action or proceeding by the indemnified party seeking an adjudication or award in arbitration pursuant to this Section 6.1. Such statement or statements shall reasonably evidence such expenses incurred by the indemnified party in connection therewith.

(f) (i) In the event that advances are not made pursuant to this Section 6.1 or payment has not otherwise been timely made, each indemnified party shall be entitled to seek a final adjudication in an appropriate court of competent jurisdiction of the entitlement of the indemnified party to indemnification or advances hereunder.

(ii) The Purchaser and the Selling Holders agree that they shall be precluded from asserting that the procedures and presumptions of this Section 6.1 are not valid, binding and enforceable. The Purchaser and the Selling Holders further agree to stipulate in any such court that the Purchaser and the Selling Holders are bound by all the provisions of this Section 6.1 and are precluded from making any assertion to the contrary.

(g) In the event that any indemnified party is a party to or intervenes in any proceeding to which the validity or enforceability of this Section 6.1 is at issue or seeks an adjudication to enforce the rights of any indemnified party under, or to recover damages for breach of, this Section 6.1, the indemnified party, if the indemnified party prevails in whole in such action, shall be entitled to recover from the indemnifying party and shall be indemnified by the indemnifying party against, any expenses reasonably incurred by the indemnified party. If it is determined that the indemnified party is entitled to indemnification for part (but not all) of the indemnification so requested, expenses incurred in seeking enforcement of such partial indemnification shall be reasonably prorated among the claims, issues or matters for which the indemnified party is entitled to indemnification and for such claims, issues or matters for which the indemnified party is not so entitled.

(h) The indemnity agreements contained in this Section 6.1 shall be in addition to any other rights (to indemnification, contribution or otherwise) 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 any Eligible Securities by any Holder.
