3.01 Ownership of Material Subsidiary Stock. For so long as any of the Notes are outstanding, the Company: 

(a) will not, nor will it permit any 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 such Material Subsidiary, nor will the Company permit any 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 such 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, free and clear of any liens, at least 80% of the issued and
outstanding Voting Stock of such Material Subsidiary after giving effect to such transaction; and 
 (b) will not permit any
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, free and clear of any liens, at least 80% of the surviving corporation’s issued and outstanding Voting
Stock; 
 (ii) lease, sell, assign or transfer all or substantially all of its properties and assets to any Person (other than

 3 







 (iii) pay any dividend in Voting Stock of a Material Subsidiary or make any other
distribution in Voting Stock of a Material Subsidiary, unless the Material Subsidiary to which the transaction relates, has obtained any necessary regulatory approvals, unconditionally guarantees payment of the principal and any premium and interest
on the Securities, unless, upon such payment or distribution the Company owns, directly or indirectly, free and clear of any liens, at least 80% of the voting stock and 80% of the value of all capital stock of such Material Subsidiary. 

Notwithstanding the foregoing, any such sale, assignment, pledge or transfer of securities, any such merger or consolidation or any such
lease, sale, assignment, pledge or transfer of properties and assets shall not be prohibited if: (A) required by law, such lease, sale, assignment or transfer of securities is made to any Person for the purpose of the qualification as required
by law of such Person to serve as a director; (B) such lease, sale, assignment or transfer 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 the merger of the Company with or into, any other Person (as to which Article V
of the Base Indenture shall apply); or (D) 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 (A)-(D), after giving effect to such disposition and acquisition, (y) at least 80% of the issued and outstanding Voting Stock and 80% of the value of

business, including, without limitation, deposit liabilities, mortgage escrow funds, reverse repurchase agreements, Federal Home Loan Bank of Pittsburgh advances, recourse obligations incurred in connection with such Material Subsidiary’s
lending activities and letters of credit. 
 3.02 No Liens. For so long as any of the Notes are outstanding, 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 the 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. Notwithstanding the foregoing, this Section shall not apply to any: 
 (a) liens for taxes, assessments or other governmental charges or levies (i) which are not yet due or are 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 $300,000 in amount;

or 
 In case the Company or the 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 or other capital stock of the Material Subsidiary (or securities convertible into, or options, warrants or rights
to subscribe for or purchase shares of that Voting Stock or other capital stock), directly or indirectly, other than as permitted by subdivisions (a) and (b) of this Section 3.02 of this Supplemental Indenture, 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, effectively secure all the Notes equally and ratably with such
indebtedness, by pledge, encumbrance or lien of such

Voting Stock and/or other capital 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 or as the Trustee shall deem necessary in connection with such pledge, encumbrance or lien. 

3.03 Other Issuances. For so long as any of the Notes are outstanding, the Company will not issue any senior indebtedness of the
Company (i) providing for a maturity date prior to the maturity date of the Notes, or (ii) providing for any redemption date, call option or right, or similar repurchase right or any rights of defeasance (whether legal defeasance, covenant
defeasance or otherwise) prior to the maturity date of the Notes. 
 ARTICLE 4 

EVENTS OF DEFAULT 
 Pursuant to Section 2.2.18 and Section 6.1(g) of the Base Indenture, “Event of Default”, whenever used with respect to the Notes, shall include with respect to the Company or the

an aggregate principal amount outstanding of at least $1,000,000 or under any mortgage, indenture or instrument (including this 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 the Material Subsidiary having an aggregate principal amount outstanding of at least $1,000,000, whether such indebtedness now exists or is created or incurred 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), such indebtedness having been discharged or such acceleration having been rescinded or annulled;
provided, that for purposes of Article 4 of this Supplemental Indenture, the term “indebtedness” shall not include any obligations of the Company or the Material Subsidiary pursuant to a lease where the Company or Material Subsidiary is a
