The Company and its subsidiaries are in compliance with the terms and conditions of all Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, result in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, singly or in the aggregate, result in a Material Adverse Effect.

SECTION 2. Sale and Delivery to Initial Purchasers; Closing.

(a) Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Initial Purchaser, severally and not jointly, and each Initial Purchaser, severally and not jointly, agrees to purchase from the Company, at the price equal to 99% of the aggregate principal amount of, the Securities as listed on Schedule A, the number of Securities set forth in Schedule A opposite the name of such Initial Purchaser.

(b) Payment. Payment of the purchase price for, and delivery of certificates for, the Securities shall be made at the offices of XxXxxxxxx Will & Xxxxx LLP, 000 Xxxx Xxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, XX 00000 or at such other place as shall be agreed upon by the Representatives and the Company, at 10:00 A.M. (New York City time) on November 16, 2017, or such other time not later than ten business days after such date as shall be agreed upon by the Representative and the Company (such time and date of payment and delivery being herein called “Closing Time”).

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company against delivery to the Representative for the respective accounts of the Initial Purchasers of Securities to be purchased by them. It is understood that each Initial Purchaser has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Securities, which it has agreed to purchase. The Representative, individually and not as representative of the Initial Purchasers, may (but shall not be obligated to) make payment of the purchase price for the Securities, to be purchased by any Initial Purchaser whose funds have not been received by the Closing Time, as the case may be, but such payment shall not relieve such Initial Purchaser from its obligations hereunder. The Company shall deliver the Securities through the facilities of DTC unless the Representative shall otherwise instruct.

SECTION 3. Covenants of the Company. The Company covenants with each Initial Purchaser as follows:

(a) Compliance with Requests by Representative. The Company, as promptly as possible, will furnish to the Representative, without charge, such number of copies of the Preliminary Offering Circular, the Final Offering Circular and any amendments and supplements thereto as the Representative may reasonably request.

(b) Proposals of Amendments or Supplements. The Company will advise the Representative promptly of any proposal to amend or supplement the Offering Circular and will not effect such amendment or supplement without the consent of the Representative, which consent shall not be unreasonably withheld. Neither the consent of the Representative, nor the Representative’s delivery of any such amendment or supplement, shall constitute a waiver of any of the conditions set forth in Section 5 hereof.

(c) Delivery of Offering Circulars. Before issuing, making, authorizing or approving any written communications regarding the Securities or the Offering Circular, the Company will furnish to the Representative a copy of such communication for review and will make such changes as the Representative may reasonably request. The Company, as promptly as possible, will furnish to the Representative, without charge, such number of copies of the Preliminary Offering Circular, the Final Offering Circular and any amendments and supplements thereto as the Representative may reasonably request.

(d) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Initial Purchasers, to qualify the Securities for offering and sale under the applicable securities laws of such states and non-U.S. jurisdictions as the Representative may designate and to maintain such qualifications in effect so long as required to complete the distribution of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(e) Amendments to Final Offering Circular. Prior to the completion of the placement of the Securities by the Representative, the Company will immediately notify the Representative, and confirm such notice in writing, of (i) any filing made by the Company or its subsidiaries of information relating to the offering of the Securities with any securities exchange or any other regulatory body in the United States, and (ii) any material information, event or circumstance which shall occur as a result of which, in the reasonable opinion of the Company, its counsel, the Representative or counsel to the Initial Purchasers, the Final Offering Circular would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances then existing, and, in the case of paragraph (e)(ii) above, the Company will forthwith amend or supplement the Final Offering Circular by preparing and furnishing to the Representative an amendment or amendments of, or a supplement or supplements to, the Final Offering Circular (in form and substance satisfactory in the reasonable opinion of counsel for the Representative) so that, as so amended or supplemented, the Final Offering Circular will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered to a Subsequent Purchaser, not misleading.

(f) Additional Company Offering Documents. If at any time following issuance of an Additional Company Offering Document there occurred or occurs an event or development as a result of which such Additional Company Offering Document conflicted or would conflict with the information contained in the Offering Circular or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Initial Purchasers and will promptly amend or supplement, at its own expense, such Additional Company Offering Document to eliminate or correct such conflict, untrue statement or omission.

(g) Annual Report. During a period of three years from the date of the Final Offering Circular, the Company will furnish to the holders of the Securities as soon as practicable after the end of each fiscal year an annual report (including balance sheets and statements of income, shareholders’ equity and cash flows of the Company and its consolidated subsidiaries certified by independent public accountants) and, as soon as practicable after the end of each of the first three quarters of each fiscal year (beginning with the fiscal quarter ending after the date of the Offering Circular), consolidated summary financial information of the Company and its subsidiaries for such quarter in reasonable detail; provided that if MBFI files an annual report on Form 10-K or quarterly report on Form 10-Q by means of XXXXX, the Company shall be deemed to have furnished such reports or information to such holders in compliance with the requirements of this section.

(h) Copies of Financial Statements. During a period of three years from the date of the Offering Circular, the Company will furnish to the Initial Purchasers copies of all reports or other communications (financial or other) furnished to holders of the Securities, and deliver to the Initial Purchasers, as soon as they are available, copies of any reports and financial statements furnished to or filed with the Commission pursuant to the 1934 Act or any national securities exchange on which any class of securities of the Company is listed and (ii) subject to an appropriate confidentiality agreement, such additional information concerning the business and financial condition of the Company as the Initial Purchasers may from time to time reasonably request (such financial statements to be on a consolidated basis to the extent the accounts of the Company and its subsidiaries are consolidated in reports furnished to its shareholders generally or to the Commission); provided that if MBFI files any such reports or other communications of the type contemplated by clauses (i) or (ii) above with the Commission and such report or materials are or will become available on XXXXX, or if the Company files any such reports or other communications of the type contemplated by clauses (i) or (ii) above with the FFIEC or such reports or materials are or will become available on the FFIEC website, the Company shall be deemed to have

furnished such report or other communications to the Initial Purchasers in compliance with the requirements of this section.

(i) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Offering Circular and the General Disclosure Package under “Use of Proceeds.”

(j) Restriction on Sale of Securities. During a period of 30 days from the date of this Agreement, the Company will not, without the prior written consent of the Representative, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or lend or otherwise transfer or dispose of, the Securities or any securities that are substantially similar to the Securities, whether owned as of the date hereof or hereafter acquired or with respect to which such person has or hereafter acquires the power of disposition, or file, or cause to be filed, any registration statement under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Securities or such other securities that are substantially similar to the Securities, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of any Securities or such other securities, in cash or otherwise. The foregoing sentence shall not apply to the Securities to be sold hereunder.

(k) Final Term Sheet. The Company will prepare a final term sheet (the “Final Term Sheet”) containing only a description of the final terms of the Securities and their offering, in a form approved by the Initial Purchasers and attached as Schedule C hereto. The Company will furnish to each Initial Purchaser, without charge, copies of the Final Term Sheet promptly upon its completion.

(l) Stabilization of the Price of Securities. The Company will not take, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of any securities of the Company, whether to facilitate the sale or resale of the Securities or otherwise, and the Company will, and shall use its commercially reasonable efforts to cause each of its affiliates to, comply with all applicable provisions of Regulation M with respect to any securities of the Company. If the limitations of Rule 102 of Regulation M (“Rule 102”) do not apply with respect to the Securities or any other reference security pursuant to any exception set forth in Section (d) of Rule 102, then promptly upon notice from the Representative (or, if later, at the time stated in the notice), the Company will, and shall use its commercially reasonable efforts to cause each of its affiliates to, comply with Rule 102 as though such exception were not available, but the other provisions of Rule 102 (as interpreted by the Commission) did apply.

(m) DTC. The Company will cooperate with the Initial Purchasers and use its best efforts to permit the Securities to be eligible for clearance, settlement and trading through the facilities of DTC.

SECTION 4. Payment of Expenses.

(a) Expenses. Except as otherwise agreed by the Company and the Initial Purchasers, the Company will pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including (i) the reasonable out-of-pocket expenses incurred by the Initial Purchasers in connection with their engagement in excess of $75,000, including without limitation, outside legal fees and expenses, marketing, syndication and travel expenses, provided that the portion of the outside legal fees and expenses incurred by the Initial Purchasers which the Company must pay or cause to be paid shall not exceed $75,000, (ii) the preparation, printing and delivery to the Initial Purchasers of copies of each Offering Circular and any amendments or supplements thereto and any costs associated with electronic

SECTION 6. Indemnification.

(a) Indemnification of Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial Purchaser, its affiliates (as such term is defined in Rule 501(b) of the 1933 Act Regulations (each, an “Affiliate”)), selling agents, partners, officers and directors 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 as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Offering Circular or the General Disclosure Package, , or any amendment or supplement thereto, or the omission or alleged omission therefrom of a material fact or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any Marketing Materials 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 any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) hereof) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representative), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any Governmental Entity, commenced or threatened, or any claim whatsoever 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 any untrue statement or omission or alleged untrue statement or omission made in any Offering Circular, the General Disclosure Package, , or any amendment or supplement thereto in reliance upon and in conformity with the Initial Purchaser Information.

(b) Indemnification of Company, Directors and Officers. Each Initial Purchaser severally agrees to indemnify and hold harmless the Company, its directors, its officers, 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 against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the any Offering Circular, the General Disclosure Package, , or any amendment or supplement thereto, in reliance upon and in conformity with the Initial Purchaser Information.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) hereof, counsel to the indemnified parties shall be selected by the Representative, and, in the case of parties indemnified pursuant to Section 6(b) hereof, counsel to the indemnified parties shall be selected by the Company. 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 prior written consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties 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 Entity, 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, 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, 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, on the one hand, and 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, 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, on the one hand, and the total underwriting discount received by the Initial Purchasers, on the other hand, in each case as set forth in the table on the cover of the Final Offering Circular, bear to the initial public offering price of the Securities as set forth on the Final Offering Circular.

The relative fault of the Company, 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 or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company 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 Entity, 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 underwriting discount received by such Initial Purchaser in connection with the Securities underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Initial Purchaser’s Affiliates, partners, officers, directors and selling agents shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company, 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. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Initial Purchaser or its Affiliates, partners, officers, directors and or selling agents, any person controlling any Initial Purchaser or the Company’s officers or directors or any person controlling the Company and (ii) delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination. The Representative may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time, (i) if there has been, in the judgment of the Representative, since the time of execution of this Agreement or since the respective dates as of which information is given in the Offering Circular or the General Disclosure Package, any Material Adverse Change, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to proceed with the completion of the offering of the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of MBFI has been suspended or materially limited by the Commission or the Nasdaq Global Market, or (iv) if trading generally on the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other Governmental Entity, or (v) if a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by either Federal, New York, Illinois or Maryland authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 14, 15 and 16 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Initial Purchasers. If one or more of the Initial Purchasers shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Initial Purchasers, or any other initial purchasers, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Initial Purchasers, or

(ii) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased, this Agreement, the obligation of the Initial Purchasers to purchase, and the Company to sell shall terminate without liability on the part of any non-defaulting Initial Purchaser.

No action taken pursuant to this Section shall relieve any defaulting Initial Purchaser from liability in respect of its default.
