(i)against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of or based upon any untrue statement or alleged untrue statement of a material fact in the Preliminary Offering Memorandum, any Issuer Free Writing Document, the General Disclosure Package or the Offering Memorandum (or any amendment or supplement to any of the foregoing), or in any materials, presentations or information provided to investors by, or with the approval of, the Company or any Guarantor in connection with the marketing of the offering of the Securities, including any road show or investor presentations made available to investors by the Company or the Parent (whether in person or electronically), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii)against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of, or pursuant to a judgment or other disposition in, any litigation, or any investigation or proceeding by any governmental or self-regulatory agency or body, commenced or threatened, or of any claim whatsoever arising out of or based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company and the Guarantors; and

(iii)against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably incurred in investigating, preparing or

defending against any litigation, or any investigation or proceeding by any governmental or self-regulatory agency or body, commenced or threatened, or any claim whatsoever arising out of or based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information about any Initial Purchaser furnished to the Company or any Guarantor by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any Issuer Free Writing Document, the General Disclosure Package or the Offering Memorandum (or in any amendment or supplement to any of the foregoing), it being understood and agreed that the only such information furnished by the Initial Purchasers as aforesaid consists of the information described as such in Section 6(b) hereof.

(b)Indemnification by the Initial Purchasers. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company and the Guarantors, their respective affiliates, officers, directors, employees, agents, partners and members and each person, if any, who controls the Company or the Guarantors within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Preliminary Offering Memorandum, any Issuer Free Writing Document or the Offering Memorandum (or any amendment or supplement to any of the foregoing), in reliance upon and in conformity with written information relating to such Initial Purchaser furnished to the Company or any Guarantor by such Initial Purchaser through the Representative expressly for use therein. The Company and the Guarantors hereby acknowledge and agree that the information furnished to the Company and any Guarantor by the Initial Purchasers through the Representative expressly for use in the Preliminary Offering Memorandum, any Issuer Free Writing Document or the Offering Memorandum (or any amendment or supplement to any of the foregoing), consists exclusively of the following information appearing under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum: the fourth paragraph, the third and fourth sentences of the sixth paragraph and the ninth, tenth and eleventh paragraphs, all under such caption.

(c)Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action (including any proceeding, governmental or regulatory investigation) commenced against it in respect of which indemnity may be sought hereunder; provided, however, that the failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability that it may have under this Section 6; provided further, that the failure to so notify such indemnifying party shall not relive such indemnifying party from any liability that it may have to such indemnified party otherwise than under this Section 6. Counsel to the indemnified parties shall be selected as follows: counsel to the Initial Purchasers and the other indemnified parties referred to in Section 6(a) above shall be selected by RBC; and counsel to the Company, the Parent and the Guarantors, their respective affiliates, officers, directors, employees, agents, partners and members and each person, if any, who controls the Company or the Guarantors within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Company and the Guarantors. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Initial

Purchasers and the other indemnified parties referred to in Section 6(a) above; and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Company and the Guarantors, their respective affiliates, officers, directors, employees, agents, partners and members and each person, if any, who controls the Company or the Guarantors within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) 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.

(d)Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors on the one hand and of the Initial Purchasers on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the Guarantors and the total discounts and commissions received by the Initial Purchasers, in each case as determined pursuant to this Agreement, bear to the aggregate initial offering price of the Securities as set forth on the cover of the Offering Memorandum.

The relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors on the one hand or by the Initial Purchasers on the other hand and the parties’ relative intent,

knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale to Eligible Purchasers of the Securities initially purchased by it exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

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.

For purposes of this Section 7, each affiliate, officer, director, employee, partner and member of each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Initial Purchaser, and each of the respective affiliates, officers, directors, employees, agents, partners and members of the Company and each Guarantor, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company and the Guarantors. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of the Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Company or any of their subsidiaries (whether signed on behalf of such officer, the Company or such subsidiary) and delivered to the Representative or counsel to the Initial Purchasers, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser, its affiliates and any of their any officers, directors, employees, partners, members or agents of any Initial Purchaser or any person controlling any Initial Purchaser, or by or on behalf of the Company, any Guarantor, any of their affiliates, officers, directors, employees, agents, partners and members or any person controlling the Company or any Guarantor, and shall survive delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a)Termination; General. The Representative may terminate this Agreement, by notice to the Company and the Guarantors, at any time on or prior to the Closing Date (i) if there has been, at any time on or after the date of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Offering Memorandum (in each case exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any material adverse change or any development that could reasonably be expected
