COVENANTS

Pursuant to Section 2.2.19 of the Base Indenture, so long as any of the Notes are outstanding, the following provisions shall be applicable to the Notes in addition to the covenants contained in Article IV of the Base Indenture:

Section 3.01 Ownership of Material Subsidiary Stock. Subject to the provisions of Article V of the Base Indenture, so long as any of the Notes are outstanding, the Company:

(a) will not, nor will it permit a Material Subsidiary to, directly or indirectly, sell, assign, pledge, transfer or otherwise dispose of any shares of, securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, Voting Stock of a Material Subsidiary, nor will the Company permit a Material Subsidiary to issue any shares of, or securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, Voting Stock of a Material Subsidiary if, in each case, after giving effect to any such transaction and to the issuance of the maximum number of shares of Voting Stock of such Material Subsidiary issuable upon the exercise of all such convertible securities, options, warrants or rights, the Company would cease to own, directly or indirectly, at least 80% of the issued and outstanding Voting Stock of such Material Subsidiary; and

(b) will not permit a Material Subsidiary to:

(i) merge or consolidate with or into any corporation or other Person, unless the Company is the surviving corporation or Person, or unless, upon consummation of the merger or consolidation, the Company will own, directly or indirectly, at least 80% of the surviving corporation’s issued and outstanding Voting Stock; or

(ii) lease, sell, assign or transfer all or substantially all of its properties and assets to any Person (other than the Company) in a single transaction or series of related transactions, unless, upon such sale, assignment or transfer, the Company will own, directly or indirectly, at least 80% of the issued and outstanding Voting Stock of that Person.

Notwithstanding the foregoing, any such sale, assignment, pledge, transfer, disposition or issuance of securities, any such merger or consolidation or any such lease, sale, assignment or transfer of properties and assets shall not be prohibited if: (A) required by law and such sale, assignment, pledge, transfer, disposition or issuance of securities is made to any Person for the purpose of the qualification of such Person to serve as a director; (B) such sale, assignment, pledge, transfer, disposition or issuance of securities is made by the Company or any of its Subsidiaries acting in a fiduciary capacity for any Person other than the Company or any Subsidiary; (C) made in connection with the consolidation of the Company with or the sale, lease or conveyance of all or substantially all of the assets of the Company to, or merger of the Company with or into any other Person (as to which Article V of the Base Indenture shall apply); (D) required by any law or any rule, regulation or order of any governmental agency or authority; or (E) required as a condition imposed by any law or any rule, regulation or order of any governmental agency or authority to the acquisition by the Company, directly or indirectly, through purchase of stock or assets, merger, consolidation or otherwise, of any Person; provided, that, in the case of (E) only, after giving effect to such disposition and acquisition, (y) at least 80% of the issued and outstanding Voting Stock of such Person will be owned, directly or indirectly, by the Company, and (z) the Consolidated Assets of the Company will be at least equal to 70% of the Consolidated Assets of the Company prior thereto. Nothing in this Section 3.01 shall prohibit the Company or any Material Subsidiary from the sale or transfer of assets pursuant to any securitization transaction or the pledge of any assets to secure borrowings incurred in the ordinary course of business, including, without limitation, deposit liabilities, mortgage escrow funds, reverse repurchase agreements, Federal Home Loan Bank of Pittsburgh, recourse obligations incurred in connection with a Material Subsidiary’s lending activities and letters of credit.

Section 3.02 Liens. The Company will not, nor will the Company permit a Material Subsidiary to, create, assume, incur or suffer to be created, assumed or incurred or to exist, any pledge, encumbrance or lien, as security for indebtedness for borrowed money, upon any shares of Voting Stock of a Material Subsidiary (or securities convertible into, or options, warrants or rights to subscribe for or purchase shares of that Voting Stock), directly or indirectly, without making effective provision whereby the Notes shall be equally and ratably secured with any and all such indebtedness if, treating such pledge, encumbrance or lien as a transfer of the shares of, or securities convertible into or options, warrants or rights to subscribe for or purchase shares of, Voting Stock of such Material Subsidiary subject thereto to the secured party and after giving effect to the issuance of the maximum number of shares of Voting Stock of such Material Subsidiary issuable upon the exercise of all such convertible securities, options, warrants or rights, the Company would not continue to own at least 80% of the issued and outstanding Voting Stock of such Material Subsidiary. Notwithstanding the foregoing, this Section shall not apply to any:

(a) pledge, encumbrance or lien upon any such shares of Voting Stock to secure indebtedness of the Company or a Subsidiary as part of the purchase price of such shares of Voting Stock, or incurred prior to, at the time of or within 120 days after acquisition thereof for the purpose of financing all or any part of the purchase price thereof;

(b) lien for taxes, assessments or other government charges or levies (i) which are not yet due or payable without penalty, (ii) which the Company is contesting in good faith by appropriate proceedings so long as the Company has set aside on its books such reserves as shall be required in respect thereof in conformity with GAAP or (iii) which secure obligations of less than $1 million in amount;

(c) lien of any judgment, if that judgment (i) is discharged, or stayed on appeal or otherwise, within 60 days, (ii) is currently being contested in good faith by appropriate proceedings so long as the Company has set aside on its books such reserves as shall be required in respect thereof in conformity with GAAP or (iii) involves claims of less than $1 million; or

(d) any pledge or lien on the Voting Stock of a Material Subsidiary to secure a loan or other extension of credit by a Subsidiary subject to Section 23A of the Federal Reserve Act.

In case the Company or a Material Subsidiary shall propose to create, assume, incur or suffer to be created, assumed or incurred or to exist, any pledge, encumbrance or lien, as security for indebtedness for borrowed money, upon any shares of Voting Stock of a Material Subsidiary (or securities convertible into, or options, warrants or rights to subscribe for or purchase shares of that Voting Stock), directly or indirectly, other than as permitted by subdivisions (a) to (d), inclusive, of this Section, the Company will prior thereto give written notice thereof to the Trustee, and will prior to or simultaneously with such pledge, encumbrance or lien, by supplemental indenture delivered to the Trustee, in form satisfactory to it, effectively secure all the Notes equally and ratably with such indebtedness, by pledge, encumbrance or lien of such Voting Stock. Such supplemental indenture shall contain the provisions, concerning the possession, control, release and substitution of encumbered and pledged property and securities and other appropriate matters which are required or permitted by the TIA (as in effect at the date of execution of such supplemental indenture) to be included in a secured indenture qualified under the TIA, and may also contain such additional and mandatory provisions permitted by the TIA as the Company and the Trustee shall deem advisable or appropriate.

Section 3.03 Waiver of Covenants. In accordance with Section 9.2 of the Base Indenture, the Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 3.01 to 3.02 hereof, inclusive, with respect to the Notes if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Notes, by act of such Holders, either shall waive such compliance in such instance or generally waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

ARTICLE IV

(d) a court having jurisdiction in the premises shall enter (i) a decree or order for relief in respect of the Company or a Material Subsidiary in an involuntary case or proceeding under any applicable Bankruptcy Law now or hereafter in effect, (ii) or a decree or order adjudging the Company or a Material Subsidiary bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment, or composition of or in respect of the Company or a Material Subsidiary under any applicable federal or state law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator or other similar official of the Company or a Material Subsidiary or for any substantial part of its property or ordering the winding up or liquidation of its affairs, shall have been entered, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

(f) The Company or a Material Subsidiary defaults under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company or a Material Subsidiary having an aggregate principal amount outstanding of at least $25,000,000, or under any mortgage, indenture or instrument (including the Indenture) under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or a Material Subsidiary having an aggregate principal amount outstanding of at least $25,000,000, whether such indebtedness now exists or is created in the future, which default (i) constitutes a failure to pay any portion of the principal of such indebtedness when due and payable after the expiration of any applicable grace period or (ii) results in such indebtedness becoming due or being declared due and payable prior to the date on which it otherwise would have become due and payable without, in the case of clause (i), such indebtedness having been discharged or, in the case of clause (ii), without such indebtedness having been discharged or such acceleration having been rescinded or annulled.

Upon becoming aware of any Event of Default, the Company shall promptly deliver to the Trustee a written statement specifying such Event of Default.

The term “Bankruptcy Law” means title 11, U.S. Code or any U.S. federal or state bankruptcy, insolvency, reorganization, receivership, conservatorship or similar law, including, without limitation, the Federal Deposit Insurance Act and the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act of 2010.

Section 5.02 Acceleration. Pursuant to Section 2.2.18 of the Base Indenture, Section 6.2 of the Base Indenture is hereby deleted and replaced in its entirety with the following:

Section 6.2 Acceleration.

(a) If any Event of Default specified in Sections 6.1(a), 6.1(b), 6.1(c) or 6.1(f) of the Base Indenture, as amended by this Third Supplemental Indenture, with respect to the Notes occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare the principal amount (or, if any of the Notes are Discount Securities, such portion of the principal amount of such Notes as may be specified in the terms thereof) of all the Notes and interest accrued thereon to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by the Holders of the Outstanding Notes) and upon any such declaration, such principal amount (or such specified portion of the principal amount) shall become immediately due and payable.

(b) If any Event of Default specified in Section 6.1(d) or 6.1(e) of the Base Indenture, as amended by this Third Supplemental Indenture, with respect to the Notes occurs, the principal amount (or, if any of the Notes are Discount Securities, such portion of the principal amount of such Notes as may be specified in the terms thereof) of all the Notes and interest accrued thereon shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable; provided, however, that if an Event of Default specified in Section 6.1(d) or 6.1(e) solely with respect to a Material Subsidiary occurs and is continuing, the principal amount of such Notes and interest accrued thereon shall not automatically become immediately due and payable, but may be accelerated by the Trustee or the Holders in accordance with the provisions of Section 6.2(a).

(c) The Holders of a majority in aggregate principal amount of the Outstanding Notes with respect to which the Event of Default has occurred, by written notice to the Company and the Trustee, may on behalf of the Holders of all of the Notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and if:

(i) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on all Notes, (B) the principal of any Notes which have become due otherwise than by such acceleration and any interest thereon at the rate or rates prescribed therefor in the Notes, (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in the Notes, and (D) all sums paid or advanced by the Trustee hereunder and the compensation and reasonable expenses, disbursements and advances of the Trustee, its agents and counsel; and

(ii) all existing Events of Default with respect to the Notes (other than the nonpayment of principal or interest that has become due solely because of the acceleration) have been cured or waived.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

(d) For all purposes under this Indenture, if a portion of the principal of any Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions of this Indenture, then, from and after the date of such Event of Default, unless such Event of Default has been rescinded and annulled as provided above, the principal amount of such Discount Securities shall be deemed, for all purposes under this Indenture, to be such portion of the principal as shall be due and payable as a result of such acceleration, and the payment of such portion of the principal as shall be due and payable as a result of such acceleration, together with interest, if any, on such portion and all other amounts owing under such Discount Security, shall constitute payment in full of such Discount Securities.

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. Interest. Customers Bancorp, Inc. (the “Company”), a Pennsylvania corporation, promises to pay CEDE & CO., or registered assigns, the principal amount of __________ ($__________) on September 25, 2024 (“Stated Maturity”) (unless redeemed on any date fixed for redemption (the “Redemption Date”) prior to the Stated Maturity in accordance with the terms of this Note and the Indenture) (the Stated Maturity and the Redemption Date is hereinafter referred to as the “Maturity Date” with respect to the principal repayable on such date) and to pay interest on the outstanding principal amount of this Note from and including September 25, 2019, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as applicable, semi-annually in arrears on March 25 and September 25 of each year, commencing on March 25, 2020 (each, an “Interest Payment Date”), and, if applicable, on the Maturity Date, at the rate of 4.50% per annum, until said principal amount is paid or duly provided for. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the required payment need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date or the Maturity Date, as the case may be, and no additional interest shall accrue on such payment as a result of payment on such next succeeding Business Day. If there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months and interest for any partial period shall be computed on the basis of a 360-day year of twelve 30-day months and the number of days elapsed in any partial month.

2. Method of Payment. The Company will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on March 10 or September 10 next preceding the applicable Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.13 of the Indenture (as herein defined) with respect to defaulted interest. For Notes held in definitive form, payments of interest may be made, at the Company’s option, by (i) mailing a check for such interest payable to or upon the written order of the Person entitled thereto, to the address of such Person as it appears on the Security Register or (ii) transfer to an account maintained by the payee located inside the United States. For Notes held in global form, payments shall be made through the Depository, or its nominee, as the registered owner of the Notes. All such payments shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

A-5

3. Paying Agent and Registrar. Initially, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

4. Indenture. This Note is one of the 4.50% Senior Notes due 2024 (the “Notes”) issued under the Indenture, dated as of July 30, 2013 (as amended, modified or supplemented from time to time in accordance therewith, other than with respect to a particular series of debt securities, the “Base Indenture” and, as amended, modified and supplemented by the Third Supplemental Indenture, dated as of September 25, 2019, the “Indenture”), by and between the Company and the Trustee. This Note is a “Global Security” and the Notes are “Global Securities” under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA as in effect on the date on which the Indenture was qualified under the TIA. The Notes are subject to all such terms, and Holders of the Notes are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

5. Optional Redemption. The Notes may be redeemed at any time on or after the date that is 30 days prior to the Stated Maturity at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at a price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Notes being redeemed to, but excluding, the Redemption Date. In addition to the Company’s right to redeem the Notes as provided in the Indenture, the Company may at any time and from time to time purchase Notes in open market transactions, tender offers or otherwise.

6. Notice of Redemption. In the event of any redemption of the notes, we will deliver or cause to be delivered a notice of redemption by first class mail, or in the event the notes are represented by global Notes, electronically in accordance with the procedures of The Depository Trust Company (“DTC”) at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address; provided that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. Notes to be redeemed shall, on the Redemption Date, become due and payable at the redemption price, and from and after such date (unless the Company shall default in the payment of the redemption price) such Notes shall cease to bear interest. The Company shall deposit with the Trustee or with the Paying Agent, one Business Day prior the Redemption Date, money sufficient to pay the redemption price on all Notes to be redeemed on that date.

7. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company and the Registrar need not exchange or register the transfer of any Note selected for redemption, in whole or in part, except for the unredeemed portion of any Note being redeemed in part. The Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the next succeeding Interest Payment Date.

A-6

8. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

9. Amendment, Supplement and Waiver. The Base Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into one or more supplemental indentures without notice to any Holder but with the written consent of the Holders of a majority in principal amount of the Securities of each Series then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities) affected by such supplemental indenture. In addition, the Base Indenture permits the Company and the Trustee to enter into one or more supplemental indentures without the consent of any Holder for certain specified purposes as therein provided, including: to cure any ambiguity, defect or inconsistency contained in the Base Indenture, in any supplemental indenture or in any Securities; to provide for uncertificated Securities in addition to or in place of certificated Securities; to make any change that would provide any additional rights or benefits to the Holders of Securities or that does not adversely affect the legal rights under the Indenture of any such Holder; to evidence the succession of another Person to the Company pursuant to Article V of the Base Indenture and the assumption by such successor of the Company’s covenants, agreements and obligations in the Base Indenture and in the Securities; to modify the Base Indenture in such a manner to comply with the requirements of the SEC or as to permit the qualification of the Base Indenture or any supplemental indenture under the TIA; to add any guarantor or to provide any collateral to secure any Notes; to add additional obligors under the Indenture and the Securities; to evidence and provide for the acceptance of appointment by a successor Trustee with respect to the Securities and matters related thereto; or to establish the form or terms of Securities of any Series pursuant to Section 2.2 of the Base Indenture. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

10. Defaults and Remedies. If any Event of Default, other than an Event of Default relating to bankruptcy, insolvency, reorganization or similar events of the Company, with respect to the Notes occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare the principal amount of all the Notes and interest accrued thereon to be due and payable immediately. If an Event of Default relating to bankruptcy, insolvency, reorganization or similar events of the Company shall occur, the principal amount of the Notes and interest accrued thereon will become immediately due and payable without any declaration or other action on the part of the Trustee or any Holder. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Indenture permits, subject to certain limitations therein provided, Holders of not less than a majority in aggregate principal amount of the then outstanding Securities of any Series to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, with respect to the Securities of such Series. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture, except a continuing Default or Event of Default in the payment of the principal of or interest on the Notes or in respect of a covenant or provision of the Indenture which cannot be amended or modified without the consent of all Holders of the Notes.

A-7

11. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not the Trustee.

12. Discharge and Defeasance. Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Notes and the Indenture if the Company deposits with the Trustee cash in United States dollars, non-callable U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay and discharge the entire indebtedness on the outstanding Notes for principal and accrued interest, to the date of maturity or redemption, as the case may be.

13. No Recourse Against Others. No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in this Note, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, shareholder, employee, officer, or director, as such, past, present or future, of the Company, either directly or through the Company, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that the Indenture, this Note and the obligations issued hereunder are solely obligations of the Company, and that no such personal liability whatever shall attach to, or is or shall be incurred by, the incorporators, shareholders, employees, officers or directors, as such, of the Company, or any of them, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in the Indenture or in any Security or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution or statute or otherwise, of, and any and all such rights and claims against, every such incorporator, shareholder, employee, officer or director, as such, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in the Indenture or in any Security or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for the issuance of the Notes.
