21

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless, the Company, its officers and employees, each of its directors, and each person, if any, who controls the Company within the meaning of the Securities Act from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Time of Sale Prospectus, any issuer free writing prospectus, or the Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in the Registration Statement, the Time of Sale Prospectus, any issuer free writing prospectus, or the Prospectus or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein (and with respect to the Time of Sale Prospectus, the Prospectus or any such free writing prospectus, in the light of the circumstances under which such statements are made) not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with the written information furnished to the Company through the Representatives by or on behalf of that Underwriter expressly for inclusion therein (which consists of the information specified in Section 1(c)), and shall reimburse the Company and any such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Company or any such director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under Section 8(a), 8(b) or 8(d) except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Underwriters shall each have the right to employ separate counsel to represent the Underwriters and their respective affiliates, directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under this Section 8 if, in the reasonable judgment of counsel to such Underwriters it is advisable for such

22

Underwriters, affiliates, directors, officers, employees and controlling persons to be jointly represented by separate counsel, due to the availability of one or more legal defenses to them which are different from or additional to those available to the indemnifying party, and in that event the reasonable fees and expenses of such separate counsel shall be paid by the Company; provided further, that the Company shall not be liable for the fees and expenses of more than one separate firm of attorneys (in addition to one local counsel in each relevant jurisdiction) at any time for all such indemnified parties. No indemnifying party shall, (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld) settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable or insufficient to hold harmless an indemnified party under Section 8(a), 8(b) or 8(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, other than to the extent that such indemnification is unavailable or insufficient due to a failure to provide prompt notice in accordance with Section 8(c), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares, or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) but also the relative fault of the Company on the one hand and the Underwriters on the other with respect to the statements or omissions or alleged statements or alleged omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares purchased under this Agreement (before deducting expenses) received by the Company on the one hand, and the total underwriting discounts and commissions realized or received by the Underwriters with respect to the Shares purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Shares under this Agreement, in each case, as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the 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 the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if the amount of contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such

23

purpose) or by any other method of allocation, which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

9. Defaulting Underwriters. If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining nondefaulting Underwriters shall be obligated to purchase the number of Shares which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of the Shares set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the aggregate number of Shares set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Shares on such Delivery Date if the total number of Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the total aggregate number of the Shares to be purchased on the applicable Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the aggregate number of the Shares which it agreed to purchase on the applicable Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, the total number of Shares to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase on such Delivery Date the aggregate number of Shares which the defaulting Underwriters agreed but failed to purchase, this Agreement (or with respect to the Option Delivery Date, the obligation of the Underwriters to purchase the Option Shares) shall terminate without liability on the part of any non-defaulting Underwriter and the Company, except that the Company will continue to be severally liable for the payment of expenses to the extent set forth in Sections 6 and 11 and that the provisions of Section 8 hereof shall not terminate and shall remain in effect. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 9, purchases Shares which a defaulting Underwriter agreed but failed to purchase.

24

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other underwriters are obligated or agree to purchase the Shares of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the applicable Delivery Date for up to seven full business days in order to effect any changes that, in the opinion of counsel to the Company or counsel to the Underwriters, may be necessary in the Prospectus or in any other document or arrangement.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Underwriters by notice given to and received by the Company prior to delivery of and payment for the Shares if, prior to that time, any of the events described in Sections 7(l), 7(m) or 7(n) shall have occurred or if the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement.

11. Reimbursement of Underwriters Expenses. If (a) the Company shall fail to tender the Shares for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company (including, without limitation, with respect to the transactions) is not fulfilled (other than as a result of the condition described in Section 7(n)) or (b) the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement (including the termination of this Agreement pursuant to Section 10) (other than as a result of the condition described in Section 7(n), the Company shall reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Shares, and upon demand the Company shall pay the full amount thereof to the Underwriters. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

12. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Underwriters with respect to the preparation of any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and (iii) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

to the Underwriting Agreement (as defined below)

745 Seventh Avenue

New York, New York 10019

New York, New York 10179

Dear Ladies and Gentlemen:

The undersigned understands that you propose to enter into a Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by you and such other firms as underwriters (the “Underwriters”) of 6,172,840 shares of Common Stock, par value $0.01 per share (the “Shares”) (or up to 7,098,766 Shares to the extent the underwriters exercise their option to purchase additional Shares) of Reinsurance Group of America, Incorporated, a Missouri corporation (the “Company”), and that the Underwriters propose to reoffer the Shares in a public offering (the “Offering”). Terms not defined herein are used as defined in the Underwriting Agreement.

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, for a period of 60 days after the date of the Prospectus (such period, the “Restricted Period”) not to (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any Common Stock or any other securities that are substantially similar to the Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or such other securities or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of any of the Common Stock or such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of any of the Common Stock or such other securities, in cash or otherwise, without the prior written consent of the Representatives, which consent shall not be unreasonably withheld or delayed.

The immediately preceding paragraph shall not apply to:

(a) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock by will or intestate succession,

(b) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock as a bona fide gift,

(c) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to any member of the immediate family of the undersigned, or to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned,

(d) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to a corporation, partnership, limited liability company, investment fund or other entity that controls or is controlled by, or is under common control with, the undersigned, or is wholly-owned by the undersigned and/or by members of the immediate family of the undersigned,

(e) dispositions of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock acquired in open market transactions after the completion of the Offering,

(f) dispositions to the Company solely in connection with the “cashless” exercise of stock options (the term “cashless” exercise being intended to include the sale of a portion of the option shares or previously owned shares to the Company to cover payment of the exercise price) for the purpose of exercising such stock options solely in the case of termination of employment or board service following death, disability or other than for cause (including sales in respect of tax liabilities arising from such exercise and sale) if such stock options would otherwise expire, provided that any shares of Common Stock received upon such exercise shall be subject to all of the restrictions set forth in this agreement,

(g) the forfeiture or surrender to the Company of shares of Common Stock to cover the exercise price of, or tax withholding obligations upon the vesting, exercise or delivery of, restricted share units, performance stock units, stock options and other equity based compensation granted to the undersigned pursuant to any employee equity incentive plan existing on the date hereof; ,

(h) disposition of Common Stock or securities convertible into or exchangeable or exercisable for Common Stock pursuant to any pledge, encumbrance or contract to sell established before the date of the Prospectus , and

(i) sales pursuant to any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) established before the date of the Prospectus ; provided, that any filing made under the Exchange Act in connection with such a sale shall disclose that the sale was made pursuant to a Plan entered into on a date before the date of the Prospectus,

2

provided that in the case of any gift, transfer or distribution pursuant to clause (a), (b), (c) or (d), each donee, transferee or distributee shall sign and deliver an agreement substantially in the form of this letter, and, provided, further, that in the case of any sale, gift, disposition, distribution or other transfer pursuant to clause (b), (c), (d) or (e), no filing under the Exchange Act, reporting a reduction in beneficial ownership of shares of the Company shall be required or shall be voluntarily made during the Restricted Period in connection with any such sale, gift, disposition, distribution or other transfer.

Nothing in this agreement shall prevent the establishment of a Plan that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act for the transfer of shares of Common Stock, provided that (1) such Plan does not provide for the transfer of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock during the Restricted Period and (2) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such Plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such Plan during the Restricted Period.

For purposes hereof, “immediate family” shall mean spouse, lineal descendant, father, mother, brother, sister or domestic partner of the transferor, whether by law or otherwise, or any grandparent, mother-in-law, father-in-law, daughter-in-law, brother-in-law, stepchild, grandchild or step-grandchild, uncle, aunt, niece or nephew of the transferor, and which shall include adoptive relationships.

In addition, notwithstanding the foregoing, the undersigned may pledge any such Common Stock or securities convertible into or exchangeable or exercisable for Common Stock in connection with a bona fide loan transaction in which the pledgee acknowledges in writing the undersigned’s obligations hereunder and which pledge does not permit the pledgee, directly or indirectly, to make any offer, sale, transfer or other disposition of such Common Stock or securities convertible into or exchangeable or exercisable for Common Stock during such 60-day period.

Further, the undersigned may exercise any options, warrants or other rights to acquire Common Stock of the Company, provided that the Common Stock issued upon exercise shall remain subject to this Agreement.

In furtherance of the foregoing, the Company and the Transfer Agent are hereby authorized to decline to make any transfer of Common Stock if such transfer would constitute a violation or breach of this Agreement.

It is understood that, if the Company notifies you that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective by July 1, 2020, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock, the undersigned will be released from the obligations under this Agreement and this Agreement shall be void and without effect.

3

The undersigned understands that the Company and the Underwriters will proceed with the Offering in reliance on this Agreement. Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to a Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

4

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
