AMENDMENT NO. 1 TO THE CREDIT AGREEMENT (this “Amendment”; and such Credit
Agreement, as amended, restated, supplemented or otherwise modified from time to
time, the “Credit Agreement”) dated as of May 25, 2020, among REGENERON
PHARMACEUTICALS, INC., a New York corporation (the “Borrower”), the Lenders
party thereto, and GOLDMAN SACHS BANK USA, as administrative agent thereunder
(the “Administrative Agent”).
WHEREAS, the Borrower and the Lenders parties hereto are parties to the Credit
Agreement. Capitalized terms not otherwise defined in this Amendment have the
same meanings as specified in the Credit Agreement.
WHEREAS, the Borrower and the Lenders parties hereto have agreed to amend the
Credit Agreement pursuant to Section 9.02 of the Credit Agreement as hereinafter
set forth.
NOW, THEREFORE, in consideration of the premises and agreements, provisions and
covenants herein contained and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:
SECTION 1. Amendment to Credit Agreement. The Credit Agreement is, effective as
of the date hereof and subject to the satisfaction of the conditions precedent
set forth in Section 2, hereby amended as follows:
(a) Section 1.01 of the Credit Agreement is amended to insert the following
defined terms therein in the appropriate alphabetical order:
““Margin Stock” has the meaning assigned to such term in Regulation U.”
““Regulation U” means Regulation U of the Board as from time to time in effect
and all official rulings and interpretations thereunder or thereof.”
(b) Section 2.14(a) of the Credit Agreement is deleted and replaced as follows:
“(a) [Reserved].”
(c) Section 9.19 of the Credit Agreement is added with the following language:
“SECTION 9.19. Acknowledgement Regarding Any Supported QFCs. To the extent that
the Loan Documents provide support, through a guarantee or otherwise, for any
Swap Agreement or any other agreement or instrument that is a QFC (such support,
“QFC Credit Support”, and each such QFC, a “Supported QFC”), the parties
acknowledge and agree as follows with respect to the resolution power of the
Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act
and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act
(together with the regulations promulgated thereunder, the “U.S. Special
Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support
(with the provisions below applicable notwithstanding that the Loan Documents
and any Supported QFC may in fact be stated to be governed by the laws of the
State of New York and/or of the United States or any other state of the United
States):

--------------------------------------------------------------------------------

(a) In the event a Covered Entity that is party to a Supported QFC (each, a
“Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution
Regime, the transfer of such Supported QFC and the benefit of such QFC Credit
Support (and any interest and obligation in or under such Supported QFC and such
QFC Credit Support, and any rights in property securing such Supported QFC or
such QFC Credit Support) from such Covered Party will be effective to the same
extent as the transfer would be effective under the U.S. Special Resolution
Regime if the Supported QFC and such QFC Credit Support (and any such interest,
obligation and rights in property) were governed by the laws of the United
States or a state of the United States. In the event a Covered Party or a BHC
Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S.
Special Resolution Regime, Default Rights under the Loan Documents that might
otherwise apply to such Supported QFC or any QFC Credit Support that may be
exercised against such Covered Party are permitted to be exercised to no greater
extent than such Default Rights could be exercised under the U.S. Special
Resolution Regime if the Supported QFC and the Loan Documents were governed by
the laws of the United States or a state of the United States. Without
limitation of the foregoing, it is understood and agreed that rights and
remedies of the parties with respect to a Defaulting Lender shall in no event
affect the rights of any Covered Party with respect to a Supported QFC or any
QFC Credit Support.
(b) As used in this Section 9.19, the following terms have the following
meanings:
“BHC Act Affiliate” of a party means an “affiliate” (as such term is defined
under, and interpreted in accordance with, 12 U.S.C. 1841(k)) of such party.
“Covered Entity” means any of the following: (i) a “covered entity” as that term
is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a
“covered bank” as that term is defined in, and interpreted in accordance with,
12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and
interpreted in accordance with, 12 C.F.R. § 382.2(b).
“Default Right” has the meaning assigned to that term in, and shall be
interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as
applicable.
“QFC” has the meaning assigned to the term “qualified financial contract” in,
and shall be interpreted in accordance with, 12 U.S.C. 5390(c)(8)(D).”
(d) Section 8.01(f) of the Credit Agreement is deleted and replaced as follows:
“(f) The Administrative Agent may at any time give its notice of resignation to
the Lenders and the Borrower. Upon delivery of any such notice of resignation,
the Required Lenders shall have the right (with the consent of the Borrower
(such consent not to be unreasonably withheld or delayed); provided that no
consent of the Borrower shall be required if an Event of Default has occurred
and is continuing); to appoint a successor. If no successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within thirty (30) days after the retiring Administrative Agent gives notice of
its resignation (the “Resignation Effective Date”), then the retiring
Administrative Agent may (but shall not be obligated to), on behalf of the
Lenders, appoint a successor Administrative Agent which shall be a bank with an
office in New York, New York, or an Affiliate of any such bank. Whether or not
such successor has been appointed, such resignation shall become effective in
accordance with such notice on the Resignation Effective Date. With effect from
the Resignation Effective Date (1) the retiring or removed Administrative Agent
shall be discharged from its duties and obligations hereunder and under the
other Loan Documents and (2) except for any indemnity payments or other amounts
then owed to the retiring or removed Administrative Agent, all payments,
communications and determinations provided to be made by, to or through the
Administrative Agent shall instead be made by or to each Lender directly, until
such time, if any, as the Required Lenders appoint a successor Administrative
Agent as provided for above. Upon the acceptance of its appointment as
Administrative Agent hereunder by a successor, such successor shall succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder. The fees payable by the
Borrower to a successor Administrative Agent shall be the same as those payable
to its predecessor unless otherwise agreed between the Borrower and such
successor.

--------------------------------------------------------------------------------

After the Administrative Agent’s resignation hereunder, the provisions of this
Article and Section 9.03 shall continue in effect for the benefit of such
retiring Administrative Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them
while it was acting as Administrative Agent.”
SECTION 2. Conditions to Effectiveness. This Amendment shall become effective as
of the date first above written when, and only when, the Administrative Agent
shall have received counterparts of this Amendment executed by the Borrower and
the Required Lenders and all reasonable and documented out-of-pocket costs and
expenses in connection with the preparation, execution, and delivery of this
Amendment (to the extent invoiced at least one (1) Business Day prior to the
date hereof). This Amendment is subject to the provisions of Section 9.02 of the
Credit Agreement.

including the Federal Electronic Signatures in Global and National Commerce Act,
