Exhibit 10.20

 

INDEMNIFICATION
AGREEMENT

 

This Indemnification Agreement
(“Agreement”) is made as of [●], 20[●] by and between Xilio Therapeutics, Inc., a Delaware corporation (the
 “Company”), and [●] (“Indemnitee”). This Agreement supersedes and replaces any and all previous Agreements
between the Company and Indemnitee covering the subject matter of this Agreement. [[Solely with respect to officers and directors that
execute this form of indemnification agreement on or prior to the Company’s initial public offering:] and shall be effective
as of the effectiveness of a Registration Statement on Form S-1 relating to the initial registration under the Securities Act of
1933, as amended, of shares of the Company’s common stock].

 

RECITALS

 

WHEREAS, the Board of Directors
of the Company (the “Board”) believes that highly competent persons have become more reluctant to serve publicly-held corporations
as directors or officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification
against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation;

 

WHEREAS, the Board has determined
that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense,
liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such
insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company
believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums
and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises
are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally
would have been brought only against the Company or business enterprise itself. The certificate of incorporation of the Company (as the
same may be amended or restated from time to time, the “Certificate of Incorporation”) requires indemnification of the officers
and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State
of Delaware (the “DGCL”). The Certificate of Incorporation and the DGCL expressly provide that the indemnification provisions
set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the
Board, officers and other persons with respect to indemnification;

 

WHEREAS, the uncertainties
relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such persons;

 

WHEREAS, the Board has determined
that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company and its stockholders
and that the Company should act to assure such persons that there will be increased certainty of such protection in the future;

 

    

     

    

 

WHEREAS, it is reasonable,
prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of, such persons
to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that
they will not be so indemnified;

 

WHEREAS, this Agreement is
a supplement to and in furtherance of the Certificate of Incorporation and any resolutions adopted pursuant thereto, as well as any rights
of Indemnitee under any directors’ and officers’ liability insurance policy, and shall not be deemed a substitute therefor,
nor to diminish or abrogate any rights of Indemnitee thereunder; [and]

 

[WHEREAS, Indemnitee
is a representative of [●] [and its affiliated investment funds] (the “Fund”), and has certain rights to indemnification
and/or insurance provided by the Fund which Indemnitee and the Fund intend to be secondary to the primary obligation of the Company to
indemnify Indemnitee as provided herein, with the Company’s acknowledgement and agreement to the foregoing being a material consideration
to Indemnitee’s willingness to serve on the Board; and]

 

WHEREAS, Indemnitee does
not regard the protection available under the Certificate of Incorporation and insurance as adequate in the present circumstances and
may not be willing to serve or continue to serve as an officer or director without adequate protection, and the Company desires Indemnitee
to serve or continue to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for
or on behalf of the Company on the condition that Indemnitee be so indemnified.

 

NOW, THEREFORE, in consideration
of the premises and the covenants contained herein, the sufficiency of which is hereby acknowledged, the Company and Indemnitee do hereby
covenant and agree as follows:

 

Section 1.         Services
to the Company. Indemnitee agrees to serve as [a director] [an officer] of the Company. Indemnitee may at any time and for any reason
resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law), in which event
the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed
an employment contract between the Company (or any of its subsidiaries or any Enterprise (as defined below)) and Indemnitee. Indemnitee
specifically acknowledges that Indemnitee’s employment with the Company (or any of its subsidiaries or any Enterprise), if any,
is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in
any written employment contract between Indemnitee and the Company (or any of its subsidiaries or any Enterprise), other applicable formal
severance policies duly adopted by the Board, or, with respect to service as a director or officer of the Company, by the Certificate
of Incorporation, the bylaws of the Company (as the same may be amended or restated from time to time, the “Bylaws”), and
the DGCL. The foregoing notwithstanding, this Agreement shall continue in force after Indemnitee has ceased to serve as [an officer] [a
director] of the Company, as provided in Section 16 hereof.

of Stock by Third Party. Any Person (as defined below) is or becomes the Beneficial Owner (as defined below), directly or indirectly,
of securities of the Company representing fifty percent (50%) or more of the combined voting power of the Company’s then outstanding
securities unless the change in relative Beneficial Ownership of the Company’s securities by any Person results solely from a reduction
in the aggregate number of outstanding shares of securities entitled to vote generally in the election of directors;

 

   ii.            Change
in Board of Directors. During any period of two (2) consecutive years (not including any period prior to the execution of this
Agreement), individuals who at the beginning of such period constitute the Board, and any new director (other than a director designated
by a person who has entered into an agreement with the Company to effect a transaction described in Sections 2(b)(i), 2(b)(iii) or
2(b)(iv)) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least
two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination
for election was previously so approved, cease for any reason to constitute at least a majority of the members of the Board;

 

   iii.           Corporate
Transactions. The effective date of a merger or consolidation of the Company with any other entity, other than a merger or consolidation
which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to
represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its ultimate parent,
as applicable) more than fifty percent (50%) of the combined voting power of the voting securities of the surviving entity or its ultimate
parent, as applicable, outstanding immediately after such merger or consolidation and with the power to elect at least a majority of the

sale or disposition by the Company of all or substantially all of the Company’s assets; or

 

  v.             Other
Events. There occurs any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A
of Regulation 14A (or a response to any similar item on any similar schedule or form) promulgated under the Exchange Act (as defined below),
whether or not the Company is then subject to such reporting requirement.

incurred by Indemnitee in connection with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement,

demand to the Company in accordance with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s
counsel as being reasonable in the good faith judgment of such counsel shall be presumed conclusively to be reasonable. Expenses, however,
shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee.

is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such
party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification
agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the
foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional
conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine
Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel
referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages arising out of or
relating to this Agreement or its engagement pursuant hereto.

mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed
proceeding, whether brought in the right of the Company or otherwise and whether of a civil, criminal, administrative, legislative, regulatory
or investigative (formal or informal) nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a party,
potential party, non-party witness or otherwise by reason of the fact that Indemnitee is or was a director or officer of the Company,
by reason of any action taken by Indemnitee (or a failure to take action by Indemnitee) or of any action (or failure to act) on Indemnitee’s
part while acting pursuant to Indemnitee’s Corporate Status, in each case whether or not serving in such capacity at the time any
liability or Expense is incurred for which indemnification, reimbursement, or advancement of Expenses can be provided under this Agreement.
If Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be

Section 3.         Indemnity
in Third-Party Proceedings. The Company shall indemnify Indemnitee in accordance with the provisions of this Section 3 if Indemnitee
is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company
to procure a judgment in its favor. Pursuant to this Section 3, Indemnitee shall be indemnified to the fullest extent permitted
by applicable law against all Expenses, judgments, fines and amounts paid in settlement (including all interest, assessments and other
charges paid or payable in connection with or in respect of such Expenses, judgments, fines and amounts paid in settlement) actually and
reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein,
if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the
Company and, in the case of a criminal Proceeding had no reasonable cause to believe that Indemnitee’s conduct was unlawful. The
parties hereto intend that this Agreement shall provide to the fullest extent permitted by law for indemnification in excess of that expressly
permitted by statute, including, without limitation, any indemnification provided by the Certificate of Incorporation, the Bylaws, vote
of the Company’s stockholders or disinterested directors or applicable law.

 

Section 4.         Indemnity
in Proceedings by or in the Right of the Company. The Company shall indemnify Indemnitee in accordance with the provisions of this
Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the
Company to procure a judgment in its favor. Pursuant to this Section 4, Indemnitee shall be indemnified to the fullest extent
permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection
with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed
to be in or not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 4
in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company,
unless and only to the extent that the Court of Chancery of the State of Delaware (the “Delaware Court”) or any court in which
the Proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances
of the case, Indemnitee is fairly and reasonably entitled to such indemnification.

 

Section 5.         Indemnification
for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of this Agreement, to the fullest
extent permitted by applicable law and to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits
or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall indemnify
Indemnitee against all Expenses actually and reasonably incurred by or on behalf of Indemnitee in connection therewith. If Indemnitee
is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims,
issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by
or on behalf of Indemnitee in connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted
by law. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by
dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

 

    -6-

     

    

 

Section 6.         Indemnification
for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the fullest extent permitted by applicable law
and to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness, is or was made (or asked) to respond
to discovery requests in any Proceeding, or otherwise asked to participate in any Proceeding to which Indemnitee is not a party, Indemnitee
shall be indemnified against all Expenses actually and reasonably incurred by or on behalf of Indemnitee in connection therewith.

 

Section 7.         Partial
Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion
of Expenses, but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof
to which Indemnitee is entitled.

 

Section 8.         Additional
Indemnification.

 

    (a)          Notwithstanding
any limitation in Sections 3, 4, or 5, the Company shall indemnify Indemnitee to the fullest extent permitted by applicable law if Indemnitee
is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company
to procure a judgment in its favor) against all Expenses, judgments, fines and amounts paid in settlement (including all interest, assessments
and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines and amounts paid in settlement)
actually and reasonably incurred by Indemnitee in connection with the Proceeding.

 

    (b)          For
purposes of Section 8(a), the meaning of the phrase “to the fullest extent permitted by applicable law” shall include,
but not be limited to:

 

   i.             to
the fullest extent permitted by the provision of the DGCL that authorizes or contemplates additional indemnification by agreement, or
the corresponding provision of any amendment to or replacement of the DGCL, and

 

   ii.            to
the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that
increase the extent to which a corporation may indemnify its officers and directors.

 

Section 9.         Exclusions.
Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification payment
in connection with any claim involving Indemnitee:

 

    (a)          for
which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with
respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or

 

    (b)         for
(i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within
the meaning of Section 16(b) of the Exchange Act (as defined in Section 2(b) hereof) or similar provisions of state
statutory law or common law, or (ii) any reimbursement of the Company by Indemnitee of any bonus or other incentive-based or equity-based
compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange
Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley
Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by Indemnitee
of securities in violation of Section 306 of the Sarbanes-Oxley Act); or (iii) any reimbursement of the Company by Indemnitee
of any compensation pursuant to any compensation recoupment or clawback policy adopted by the Board or the compensation committee of the
Board, including but not limited to any such policy adopted to comply with stock exchange listing requirements implementing Section 10D
of the Exchange Act; or

 

    -7-

     

    

 

     (c)         except
as provided in Section 14(d) of this Agreement, in connection with any Proceeding (or any part of any Proceeding) initiated
by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors,
officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to
its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company
under applicable law.

 

Section 10.        Advances
of Expenses. Notwithstanding any provision of this Agreement to the contrary (other than Section 14(d)), the Company shall advance,
to the extent not prohibited by law, the Expenses incurred by Indemnitee in connection with any Proceeding (or any part of any Proceeding)
(x) not initiated by Indemnitee or (y) initiated by Indemnitee with the prior approval of the Board as provided in Section 9(c),
and such advancement shall be made within thirty (30) days after the receipt by the Company of a statement or statements requesting such
advances from time to time, whether prior to or after final disposition of any Proceeding. Advances shall be unsecured and interest free.
Advances shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate
entitlement to indemnification under the other provisions of this Agreement. In accordance with Section 14(d), advances shall include
any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing
and forwarding statements to the Company to support the advances claimed. Indemnitee shall qualify for advances upon the execution and
delivery to the Company of this Agreement, which shall constitute an undertaking providing that Indemnitee undertakes to repay the amounts
advanced (without interest) to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company.
No other form of undertaking shall be required other than the execution of this Agreement. This Section 10 shall not apply to any
claim made by Indemnitee for which indemnity is excluded pursuant to Section 9.

 

Section 11.       Procedure
for Notification and Defense of Claim.

 

      (a)        Indemnitee
shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek indemnification or advancement of Expenses
hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. The written notification to
the Company shall include a description of the nature of the Proceeding and the facts underlying the Proceeding. To obtain indemnification
under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation
and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee
is entitled to indemnification following the final disposition of such Proceeding. The omission by Indemnitee to notify the Company hereunder
will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and
any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of
the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested
indemnification.

 

    -8-

     

    

 

     (b)         The
Company will be entitled to participate in the Proceeding at its own expense.

 

Section 12.       Procedure
Upon Application for Indemnification.

 

      (a)        Upon
written request by Indemnitee for indemnification pursuant to Section 11(a), a determination, if required by applicable law, with
respect to Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change in Control shall have occurred,
by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or (ii) if a Change in
Control shall not have occurred, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board,
(B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than
a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent
Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee or (D) if so directed by the Board, by
the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall
be made within ten (10) days after such determination. Indemnitee shall cooperate with the person, persons or entity making such
determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity
upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which
is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including attorneys’
fees and disbursements) incurred by or on behalf of Indemnitee in so cooperating with the person, persons or entity making such determination
shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company
hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company promptly will advise Indemnitee in writing with respect
to any determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or basis for which
indemnification has been denied.

 

    -9-

     

    

 

     (b)        In
the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) hereof,
the Independent Counsel shall be selected as provided in this Section 12(b). If a Change in Control shall not have occurred, the
Independent Counsel shall be selected by the Board, and the Company shall give written notice to Indemnitee advising him of the identity
of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee
(unless Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and Indemnitee
shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In either event, Indemnitee
or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been given, deliver
to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided, however, that such
objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent
Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis
of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection
is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection
is withdrawn or the Delaware Court has determined that such objection is without merit. If, within twenty (20) days after the later of
submission by Indemnitee of a written request for indemnification pursuant to Section 11(a) hereof and the final disposition
of the Proceeding, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition
the Delaware Court for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection
of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by such court or by such other person as
such court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as
Independent Counsel under Section 12(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant
to Section 14(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility
in such capacity (subject to the applicable standards of professional conduct then prevailing).

 

Section 13.       Presumptions
and Effect of Certain Proceedings.

 

      (a)        In
making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination
shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee
has submitted a request for indemnification in accordance with Section 11(a) of this Agreement, and the Company shall, to the
fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any person,
persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by its directors or
Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification
is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company
(including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense
to the action or create a presumption that Indemnitee has not met the applicable standard of conduct.

 

     (b)         Subject
to Section 14(e), if the person, persons or entity empowered or selected under Section 12 of this Agreement to determine whether
Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the
request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, be
deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material
fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the
request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day
period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the
determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating
of documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 13(b) shall
not apply (i) if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 12(a) of
this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination the Board has
resolved to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five
(75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen
(15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days
after having been so called and such determination is made thereat, or (ii) if the determination of entitlement to indemnification
is to be made by Independent Counsel pursuant to Section 12(a) of this Agreement.

      (c)        The
termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect
the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee
had reasonable cause to believe that Indemnitee’s conduct was unlawful.

 

     (d)         For
purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action
is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee
by the directors or officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or
on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or
other expert selected with reasonable care by or on behalf of the Enterprise. The provisions of this Section 13(d) shall not
be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable
standard of conduct set forth in this Agreement.

 

     (e)         The
knowledge and/or actions, or failure to act, of any director, officer, trustee, partner, managing member, fiduciary, agent or employee
of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement.

 

Section 14.       Remedies
of Indemnitee.

 

      (a)        Subject
to Section 14(e), in the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee
is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 10
of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 12(a) of
this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification
is not made pursuant to Section 5, 6 or 7 or the second to last sentence of Section 12(a) of this Agreement within ten
(10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to Section 3,
4 or 8 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification,
or (vi) the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or
institutes any litigation or other action or Proceeding designed to deny, or to recover from, Indemnitee the benefits provided or
intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of Indemnitee’s
entitlement to such indemnification or advancement of Expenses. Alternatively, Indemnitee, at Indemnitee’s option, may seek
an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration
Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the
date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 14(a); provided, however,
that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce Indemnitee’s rights under
Section 5 of this Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration.

 

    -11-

     

    

 

     (b)         In
the event that a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is not entitled
to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 shall be conducted in all respects
as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination.
In any judicial proceeding or arbitration commenced pursuant to this Section 14 the Company shall have the burden of proving Indemnitee
is not entitled to indemnification or advancement of Expenses, as the case may be.

 

     (c)         If
a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is entitled to indemnification,
the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 14,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s
statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification
under applicable law.

 

     (d)         The
Company shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced
pursuant to this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall
stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. It is the
intent of the Company that, to the fullest extent permitted by law, Indemnitee not be required to incur legal fees or other Expenses
associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise
because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. The
Company shall, to the fullest extent permitted by law, indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee,
shall (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not prohibited by
law, such Expenses to Indemnitee, which are incurred by or on behalf of Indemnitee in connection with any action brought by Indemnitee
for indemnification or advancement of Expenses from the Company under this Agreement or under any directors’ and officers’
liability insurance policies maintained by the Company if, in the case of indemnification, Indemnitee is wholly successful on the
underlying claims; if Indemnitee is not wholly successful on the underlying claims, then such indemnification shall be only to the extent
Indemnitee is successful on such underlying claims or otherwise as permitted by law, whichever is greater.

 

    -12-

     

    

 

      (e)        Notwithstanding
anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this Agreement shall
be required to be made prior to the final disposition of the Proceeding.

 

Section 15.        Non-Exclusivity;
Survival of Rights; Insurance; Subrogation.

 

      (a)        The
rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other
rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement,
a vote of stockholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision
hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by Indemnitee in
Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in Delaware law, whether
by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be afforded currently under the
Certificate of Incorporation and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement
the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or
remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other right or remedy.

 

     (b)         To
the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees,
or agents of the Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the
maximum extent of the coverage available for any such director, officer, employee or agent under such policy or policies. If, at the time
of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect,
the Company shall give prompt notice of such claim or of the commencement of a Proceeding, as the case may be, to the insurers in accordance
with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause
such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such
policies.

 

      (c)        In
the event of any payment made by the Company under this Agreement, the Company shall be subrogated to the extent of such payment to all
of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including
execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

 

     (d)         The
Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder (or for which advancement
is provided hereunder) if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract,
agreement or otherwise.

 

    -13-

     

    

 

     (e)         [The
Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by
the Fund and certain of its affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it
is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance
expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall
be required to advance the full amount of Expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments,
penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the Certificate of Incorporation or
Bylaws (or any agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors,
and (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors
for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or
payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from
the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent
of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that
the Fund Indemnitors are express third party beneficiaries of the terms of this Section 15(e).]

 

      (f)        [Except
as provided in paragraph (e) above,] [T]he Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who
is or was serving at the request of the Company as a director, officer, trustee, partner, managing member, fiduciary, employee or agent
of any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise shall
be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such other corporation, limited
liability company, partnership, joint venture, trust or other enterprise.

 

Section 16.       Duration
of Agreement. This Agreement shall continue until and terminate upon the later of: (a) ten (10) years after the date that
Indemnitee shall have ceased to serve as [a director] [an officer] or (b) one (1) year after the final termination of any Proceeding
then pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding
commenced by Indemnitee pursuant to Section 14 of this Agreement relating thereto. The indemnification and advancement of expenses
rights provided by or granted pursuant to this Agreement shall be binding upon and be enforceable by the parties hereto and their respective
successors and assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially
all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or
agent of the Company or of any other Enterprise, and shall inure to the benefit of Indemnitee and his or her spouse, assigns, heirs, devisees,
executors and administrators and other legal representatives.

 

Section 17.       Severability.
If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the
validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any
Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid,
illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted
by law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give
the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement
(including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal
or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested
thereby.

 

    -14-

     

    

 

Section 18.       Enforcement.

 

      (a)        The
Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order
to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this
Agreement in serving or continuing to serve as a director or officer of the Company.

 

     (b)         This
Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes and replaces
all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof,
including any agreement covering the subject matter of this Agreement previously entered into between the Company and Indemnitee; provided,
however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation, the Bylaws, any directors’
and officers’ insurance maintained by the Company and applicable law, and shall not be deemed a substitute therefor, nor to diminish
or abrogate any rights of Indemnitee thereunder.

 

Section 19.       Modification
and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by the parties
hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this
Agreement nor shall any waiver constitute a continuing waiver.

 

Section 20.       Notice
by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with any summons, citation, subpoena,
complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement
of Expenses covered hereunder. The failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which
it may have to Indemnitee under this Agreement or otherwise.

 

Section 21.       Notices.
All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly
given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed,
(b) mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed,
(c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have been
directed or (d) sent by facsimile transmission, with receipt of oral confirmation that such transmission has been received:

 

     (a)         If

or to any other address as may have been furnished to Indemnitee by
the Company.

 

Section 22.       Contribution.
To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee
for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether
for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim
relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances
of such Proceeding in order to reflect (i) the relative benefits received by the Company, on the one hand, and Indemnitee, on the
other hand, as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative
fault of the Company (and its other directors, officers, employees and agents) on the one hand, and Indemnitee, on the other hand, in
connection with such event(s) and/or transaction(s).

 

Section 23.       Applicable
Law and Consent to Jurisdiction. This Agreement and the legal relations among the parties shall be governed by, and construed and
enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any
arbitration commenced by Indemnitee pursuant to Section 14(a) of this Agreement, the Company and Indemnitee hereby irrevocably
and unconditionally (i) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought
only in the Delaware Court, and not in any other state or federal court in the United States of America or any court in any other country,
(ii) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of
or in connection with this Agreement, (iii) waive any objection to the laying of venue of any such action or proceeding in the Delaware
Court, and (iv) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court
has been brought in an improper or inconvenient forum.

 

Section 24.       Identical
Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against
whom enforceability is sought needs to be produced to evidence the existence of this Agreement.

 

Section 25.       Miscellaneous.
Use of the masculine pronoun shall be deemed to include usage of the feminine pronoun where appropriate. The headings of this Agreement
are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof.

indentures supplemental hereto or as provided in a Board Resolution, and set forth in an Officers’ Certificate, and they may

required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any
securities exchange on which Securities of that series may be listed, or to conform to usage.

 

Section 2.03 Denominations: Provisions for Payment.

 

The Securities shall be issuable as registered Securities and in the
denominations of one thousand U.S. dollars ($1,000) or any integral multiple thereof, subject to Section 2.01(a)(10). The Securities of
a particular series shall bear interest payable on the dates and at the rate specified with respect to that series. Subject to Section
2.01(a)(16), the principal of and the interest on the Securities of any series, as well as any premium thereon in case of redemption thereof
prior to maturity, shall be payable in the coin or currency of the United States of America that at the time is legal tender for public
and private debt, at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, the City and State of
New York. Each Security shall be dated the date of its authentication. Interest on the Securities shall be computed on the basis of a
360-day year composed of twelve 30-day months. The interest installment on any Security that is payable, and is punctually paid or duly
provided for, on any Interest Payment Date for Securities of that series shall be paid to the Person in whose name said Security (or one
or more Predecessor Securities) is registered at the close of business on the regular record date for such interest installment. In the
event that any Security of a particular series or portion thereof is called for redemption and the redemption date is subsequent to a
regular record date with respect to any Interest Payment Date and prior to such Interest Payment Date, interest on such Security will
be paid upon presentation and surrender of such Security as provided in Section 3.03.

 

Any interest on any Security that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date for Securities of the same series (herein called “Defaulted Interest”)
shall forthwith cease to be payable to the registered holder on the relevant regular record date by virtue of having been such holder;
and such Defaulted Interest shall be paid by the Company, at its election, as provided in clause (1) or clause (2) below:

 

(1) The Company may make payment of any Defaulted
Interest on Securities to the Persons in whose names such Securities (or their respective Predecessor Securities) are registered at the
close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner: the
Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security and the date
of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior
to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted
Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest
which shall not be more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt
by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such special record date and, in
the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record
date therefor to be mailed, first class postage prepaid, to each Securityholder at his or her address as it appears in the Security Register
(as hereinafter defined), not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest
and the special record date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names
such Securities (or their respective Predecessor Securities) are registered on such special record date.

 

(2) The Company may make payment of any Defaulted
Interest on any Securities in any other lawful manner not inconsistent with the requirements of any securities exchange on which such
Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee
of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

 

    6

     

    

 

Unless otherwise set forth in a Board Resolution or one or more
indentures supplemental hereto establishing the terms of any series of Securities pursuant to Section 2.01 hereof, the term
 “regular record date” as used in this Section with respect to a series of Securities and any Interest Payment Date for
such series shall mean either the fifteenth day of the month immediately preceding the month in which an Interest Payment Date
established for such series pursuant to Section 2.01 hereof shall occur, if such Interest Payment Date is the first day of a month,
or the first day of the month in which an Interest Payment Date established for such series pursuant to Section 2.01 hereof shall
occur, if such Interest Payment Date is the fifteenth day of a month, whether or not such date is a Business Day.

 

Subject to the foregoing provisions of this Section, each Security
of a series delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Security of such series shall carry
the rights to interest accrued and unpaid, and to accrue, that were carried by such other Security.

 

Section 2.04 Execution and Authentication.

 

The Securities shall be signed on behalf of the Company by one of its
Officers. Signatures may be in the form of a manual or facsimile signature.

 

The Company may use the facsimile signature of any Person who shall
have been an Officer, notwithstanding the fact that at the time the Securities shall be authenticated and delivered or disposed of such
Person shall have ceased to be such an officer of the Company. The Securities may contain such notations, legends or endorsements required
by law, stock exchange rule or usage. Each Security shall be dated the date of its authentication by the Trustee.

 

A Security shall not be valid until authenticated manually by an authorized
signatory of the Trustee, or by an Authenticating Agent. Such signature shall be conclusive evidence that the Security so authenticated
has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. At any time and
from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a written order of the Company for the authentication and delivery of such Securities,
signed by an Officer, and the Trustee in accordance with such written order shall authenticate and deliver such Securities.

 

In authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and terms thereof have been established in conformity with
the provisions of this Indenture.

 

The Trustee shall not be required to authenticate such Securities if
the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities
and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee.

 

Section 2.05 Registration of Transfer and Exchange.

 

(a) Securities of any series may be exchanged
upon presentation thereof at the office or agency of the Company designated for such purpose in the Borough of Manhattan, the City and
State of New York, for other Securities of such series of authorized denominations, and for a like aggregate principal amount, upon payment
of a sum sufficient to cover any tax or other governmental charge in relation thereto, all as provided in this Section. In respect of
any Securities so surrendered for exchange, the Company shall execute, the Trustee shall authenticate and such office or agency shall
deliver in exchange therefor the Security or Securities of the same series that the Securityholder making the exchange shall be entitled
to receive, bearing numbers not contemporaneously outstanding.

 

(b) The Company shall keep, or cause to
be kept, at its office or agency designated for such purpose in the Borough of Manhattan, the City and State of New York, or such other
location designated by the Company, a register or registers (herein referred to as the “Security Register”) in which, subject
to such reasonable regulations as it may prescribe, the Company shall register the Securities and the transfers of Securities as in this
Article provided and which at all reasonable times shall be open for inspection by the Trustee. The registrar for the purpose of registering
Securities and transfer of Securities as herein provided shall be appointed as authorized by Board Resolution (the “Security Registrar”).

 

    7

     

    

 

Upon surrender for transfer of any Security at the office or agency
of the Company designated for such purpose, the Company shall execute, the Trustee shall authenticate and such office or agency shall
deliver in the name of the transferee or transferees a new Security or Securities of the same series as the Security presented for a like
aggregate principal amount.

 

All Securities presented or surrendered for exchange or registration
of transfer, as provided in this Section, shall be accompanied (if so required by the Company or the Security Registrar) by a written
instrument or instruments of transfer, in form satisfactory to the Company or the Security Registrar, duly executed by the registered
holder or by such holder’s duly authorized attorney in writing.

 

(c) Except as provided pursuant to Section
2.01 pursuant to a Board Resolution, and set forth in an Officers’ Certificate, or established in one or more indentures supplemental
to this Indenture, no service charge shall be made for any exchange or registration of transfer of Securities, or issue of new Securities
in case of partial redemption of any series, but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge in relation thereto, other than exchanges pursuant to Section 2.06, Section 3.03(b) and Section 9.04 not involving any transfer.

 

(d) The Company shall not be required (i)
to issue, exchange or register the transfer of any Securities during a period beginning at the opening of business 15 days before the
day of the mailing of a notice of redemption of less than all the Outstanding Securities of the same series and ending at the close of
business on the day of such mailing, nor (ii) to register the transfer of or exchange any Securities of any series or portions thereof
called for redemption, other than the unredeemed portion of any such Securities being redeemed in part. The provisions of this Section
2.05 are, with respect to any Global Security, subject to Section 2.11 hereof.

 

Section 2.06 Temporary Securities.

 

Pending the preparation of definitive Securities of any series, the
Company may execute, and the Trustee shall authenticate and deliver, temporary Securities (printed, lithographed or typewritten) of any
authorized denomination. Such temporary Securities shall be substantially in the form of the definitive Securities in lieu of which they
are issued, but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined
by the Company. Every temporary Security of any series shall be executed by the Company and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the definitive Securities of such series. Without unnecessary
delay the Company will execute and will furnish definitive Securities of such series and thereupon any or all temporary Securities of
such series may be surrendered in exchange therefor (without charge to the holders), at the office or agency of the Company designated
for the purpose in the Borough of Manhattan, the City and State of New York, and the Trustee shall authenticate and such office or agency
shall deliver in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities of such series, unless
the Company advises the Trustee to the effect that definitive Securities need not be executed and furnished until further notice from
the Company. Until so exchanged, the temporary Securities of such series shall be entitled to the same benefits under this Indenture as
definitive Securities of such series authenticated and delivered hereunder.

 

Section 2.07 Mutilated, Destroyed, Lost or Stolen Securities.

 

In case any temporary or definitive Security shall become mutilated
or be destroyed, lost or stolen, the Company (subject to the next succeeding sentence) shall execute, and upon the Company’s request
the Trustee (subject as aforesaid) shall authenticate and deliver, a new Security of the same series, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed,
lost or stolen. In every case the applicant for a substituted Security shall furnish to the Company and the Trustee such security or indemnity
as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish
to the Company and the Trustee evidence to their satisfaction of the destruction, loss or theft of the applicant’s Security and
of the ownership thereof. The Trustee may authenticate any such substituted Security and deliver the same upon the written request or
authorization of any officer of the Company. Upon the issuance of any substituted Security, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the
fees and expenses of the Trustee) connected therewith.

 

    8

     

    

 

In case any Security that has matured or is about to mature shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Security, pay or authorize the payment of
the same (without surrender thereof except in the case of a mutilated Security) if the applicant for such payment shall furnish to the
Company and the Trustee such security or indemnity as they may require to save them harmless, and, in case of destruction, loss or theft,
evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of such Security and of the ownership thereof.

 

Every replacement Security issued pursuant to the provisions of this
Section shall constitute an additional contractual obligation of the Company whether or not the mutilated, destroyed, lost or stolen Security
shall be found at any time, or be enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities of the same series duly issued hereunder. All Securities shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities,
and shall preclude (to the extent lawful) any and all other rights or remedies, notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

 

Section 2.08 Cancellation.

 

All Securities surrendered for the purpose of payment, redemption,
exchange or registration of transfer shall, if surrendered to the Company or any paying agent, be delivered to the Trustee for cancellation,
or, if surrendered to the Trustee, shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly required
or permitted by any of the provisions of this Indenture. In the absence of such request the Trustee may dispose of canceled Securities
in accordance with its standard procedures and deliver a certificate of disposition to the Company. If the Company shall otherwise acquire
any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are delivered to the Trustee for cancellation.

 

Section 2.09 Benefits of Indenture.

 

Nothing in this Indenture or in the Securities, express or implied,
shall give or be construed to give to any Person, other than the parties hereto and the holders of the Securities any legal or equitable
right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all such
covenants, conditions and provisions being for the sole benefit of the parties hereto and of the holders of the Securities.

 

Section 2.10 Authenticating Agent.

 

So long as any of the Securities of any series remain Outstanding there
may be an Authenticating Agent for any or all such series of Securities which the Trustee shall have the right to appoint. Said Authenticating
Agent shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, transfer or
partial redemption thereof, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee hereunder. All references in this Indenture to the authentication of Securities
by the Trustee shall be deemed to include authentication by an Authenticating Agent for such series. Each Authenticating Agent shall be
acceptable to the Company and shall be a corporation that has a combined capital and surplus, as most recently reported or determined
by it, sufficient under the laws of any jurisdiction under which it is organized or in which it is doing business to conduct a trust business,
and that is otherwise authorized under such laws to conduct such business and is subject to supervision or examination by federal or state
authorities. If at any time any Authenticating Agent shall cease to be eligible in accordance with these provisions, it shall resign immediately.

 

Any Authenticating Agent may at any time resign by giving written notice
of resignation to the Trustee and to the Company. The Trustee may at any time (and upon request by the Company shall) terminate the agency
of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon resignation,
termination or cessation of eligibility of any Authenticating Agent, the Trustee may appoint an eligible successor Authenticating Agent
acceptable to the Company. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with
all the rights, powers and duties of its predecessor hereunder as if originally named as an Authenticating Agent pursuant hereto.

Section 2.11 Global Securities.

 

(a) If the Company shall establish pursuant
to Section 2.01 that the Securities of a particular series are to be issued as a Global Security, then the Company shall execute and the
Trustee shall, in accordance with Section 2.04, authenticate and deliver, a Global Security that (i) shall represent, and shall be denominated
in an amount equal to the aggregate principal amount of, all of the Outstanding Securities of such series, (ii) shall be registered in
the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s
instruction and (iv) shall bear a legend substantially to the following effect: “Except as otherwise provided in Section 2.11 of
the Indenture, this Security may be transferred, in whole but not in part, only to another nominee of the Depositary or to a successor
Depositary or to a nominee of such successor Depositary.”

 

(b) Notwithstanding the provisions of Section
2.05, the Global Security of a series may be transferred, in whole but not in part and in the manner provided in Section 2.05, only to
another nominee of the Depositary for such series, or to a successor Depositary for such series selected or approved by the Company or
to a nominee of such successor Depositary.

 

(c) If at any time the Depositary for a
series of the Securities notifies the Company that it is unwilling or unable to continue as Depositary for such series or if at any time
the Depositary for such series shall no longer be registered or in good standing under the Exchange Act, or other applicable statute or
regulation, and a successor Depositary for such series is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such condition, as the case may be, or if an Event of Default has occurred and is continuing and the Company
has received a request from the Depositary, this Section 2.11 shall no longer be applicable to the Securities of such series and the Company
will execute, and subject to Section 2.04, the Trustee will authenticate and deliver the Securities of such series in definitive registered
form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security
of such series in exchange for such Global Security. In addition, the Company may at any time determine that the Securities of any series
shall no longer be represented by a Global Security and that the provisions of this Section 2.11 shall no longer apply to the Securities
of such series. In such event the Company will execute and, subject to Section 2.04, the Trustee, upon receipt of an Officers’ Certificate
evidencing such determination by the Company, will authenticate and deliver the Securities of such series in definitive registered form
without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Security
of such series in exchange for such Global Security. Upon the exchange of the Global Security for such Securities in definitive registered
form without coupons, in authorized denominations, the Global Security shall be canceled by the Trustee. Such Securities in definitive
registered form issued in exchange for the Global Security pursuant to this Section 2.11(c) shall be registered in such names and in such
authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct
the Trustee. The Trustee shall deliver such Securities to the Depositary for delivery to the Persons in whose names such Securities are
so registered.

REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS

Section 3.01 Redemption.

 

The Company may redeem the Securities of any series issued hereunder
on and after the dates and in accordance with the terms established for such series pursuant to Section 2.01 hereof.

 

    10

     

    

 

Section 3.02 Notice of Redemption.

 

(a) In case the Company shall desire
to exercise such right to redeem all or, as the case may be, a portion of the Securities of any series in accordance with any right
the Company reserved for itself to do so pursuant to Section 2.01 hereof, the Company shall, or shall cause the Trustee to, give
notice of such redemption to holders of the Securities of such series to be redeemed by mailing, first class postage prepaid, a
notice of such redemption not less than 30 days and not more than 90 days before the date fixed for redemption of that series to
such holders at their last addresses as they shall appear upon the Security Register, unless a shorter period is specified in the
Securities to be redeemed. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the registered holder receives the notice. In any case, failure duly to give such notice to the holder of any
Security of any series designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of
the proceedings for the redemption of any other Securities of such series or any other series. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in
this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with any such
restriction.

 

Each such notice of redemption shall specify the date fixed for redemption
and the redemption price at which Securities of that series are to be redeemed, and shall state that payment of the redemption price of
such Securities to be redeemed will be made at the office or agency of the Company in the Borough of Manhattan, the City and State of
New York, upon presentation and surrender of such Securities, that interest accrued to the date fixed for redemption will be paid as specified
in said notice, that from and after said date interest will cease to accrue and that the redemption is for a sinking fund, if such is
the case. If less than all the Securities of a series are to be redeemed, the notice to the holders of Securities of that series to be
redeemed in part shall specify the particular Securities to be so redeemed.

 

In case any Security is to be redeemed in part only, the notice that
relates to such Security shall state the portion of the principal amount thereof to be redeemed, and shall state that on and after the
redemption date, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed
portion thereof will be issued.

 

(b) If less than all the Securities of a
series are to be redeemed, the Company shall give the Trustee at least 45 days’ notice (unless a shorter notice shall be satisfactory
to the Trustee) in advance of the date fixed for redemption as to the aggregate principal amount of Securities of the series to be redeemed,
and thereupon the Trustee shall select, by lot or in such other manner as it shall deem appropriate and fair in its discretion and that
may provide for the selection of a portion or portions (equal to one thousand U.S. dollars ($1,000) or any integral multiple thereof)
of the principal amount of such Securities of a denomination larger than $1,000, the Securities to be redeemed and shall thereafter promptly
notify the Company in writing of the numbers of the Securities to be redeemed, in whole or in part. The Company may, if and whenever it
shall so elect, by delivery of instructions signed on its behalf by an Officer, instruct the Trustee or any paying agent to call all or
any part of the Securities of a particular series for redemption and to give notice of redemption in the manner set forth in this Section,
such notice to be in the name of the Company or its own name as the Trustee or such paying agent may deem advisable. In any case in which
notice of redemption is to be given by the Trustee or any such paying agent, the Company shall deliver or cause to be delivered to, or
permit to remain with, the Trustee or such paying agent, as the case may be, such Security Register, transfer books or other records,
or suitable copies or extracts therefrom, sufficient to enable the Trustee or such paying agent to give any notice by mail that may be
required under the provisions of this Section.

 

Section 3.03 Payment Upon Redemption.

 

(a) If the giving of notice of redemption
shall have been completed as above provided, the Securities or portions of Securities of the series to be redeemed specified in such notice
shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest
accrued to the date fixed for redemption and interest on such Securities or portions of Securities shall cease to accrue on and after
the date fixed for redemption, unless the Company shall default in the payment of such redemption price and accrued interest with respect
to any such Security or portion thereof. On presentation and surrender of such Securities on or after the date fixed for redemption at
the place of payment specified in the notice, said Securities shall be paid and redeemed at the applicable redemption price for such series,
together with interest accrued thereon to the date fixed for redemption (but if the date fixed for redemption is an interest payment date,
the interest installment payable on such date shall be payable to the registered holder at the close of business on the applicable record
date pursuant to Section 2.03).

 

(b) Upon presentation of any Security of
such series that is to be redeemed in part only, the Company shall execute and the Trustee shall authenticate and the office or agency
where the Security is presented shall deliver to the holder thereof, at the expense of the Company, a new Security of the same series
of authorized denominations in principal amount equal to the unredeemed portion of the Security so presented.

Section 3.04 Sinking Fund.

 

The provisions of Sections 3.04, 3.05 and 3.06 shall be applicable
to any sinking fund for the retirement of Securities of a series, except as otherwise specified as contemplated by Section 2.01 for Securities
of such series.The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred
to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities
of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 3.05. Each sinking fund payment
shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

 

Section 3.05 Satisfaction of Sinking Fund Payments with Securities.

 

The Company (i) may deliver Outstanding Securities of a series and
(ii) may apply as a credit Securities of a series that have been redeemed either at the election of the Company pursuant to the terms
of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in
each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be
made pursuant to the terms of such Securities as provided for by the terms of such series, provided that such Securities have not been
previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the redemption price specified
in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

 

Section 3.06 Redemption of Securities for Sinking Fund.

 

Not less than 45 days prior to each sinking fund payment date for any
series of Securities (unless a shorter period shall be satisfactory to the Trustee), the Company will deliver to the Trustee an Officers’
Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of the series, the portion
thereof, if any, that is to be satisfied by delivering and crediting Securities of that series pursuant to Section 3.05 and the basis
for such credit and will, together with such Officers’ Certificate, deliver to the Trustee any Securities to be so delivered. Not
less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 3.02 and cause notice of the redemption thereof to be given in the name of and at
the expense of the Company in the manner provided in Section 3.02. Such notice having been duly given, the redemption of such Securities
shall be made upon the terms and in the manner stated in Section 3.03.

Company shall, by written notice signed by any officer authorized to sign an Officers’ Certificate and delivered to the
Trustee, designate some other office or agency for such purposes or any of them. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, notices and
demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, notices and demands. The Company initially appoints the Corporate Trust Office of the Trustee
located in the Borough of Manhattan, the City of New York as its paying agent with respect to the Securities.

Section 4.03 Paying Agents.

 

(a) If the Company shall appoint one or
more paying agents for all or any series of the Securities, other than the Trustee, the Company will cause each such paying agent to execute
and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section:

 

(1) that it will hold all sums held by it
as such agent for the payment of the principal of (and premium, if any) or interest on the Securities of that series (whether such sums
have been paid to it by the Company or by any other obligor of such Securities) in trust for the benefit of the Persons entitled thereto;

 

(2) that it will give the Trustee notice of
any failure by the Company (or by any other obligor of such Securities) to make any payment of the principal of (and premium, if any)
or interest on the Securities of that series when the same shall be due and payable;

 

(3) that it will, at any time during the continuance
of any failure referred to in the preceding paragraph (a)(2) above, upon the written request of the Trustee, forthwith pay to the Trustee
all sums so held in trust by such paying agent; and

 

(4) that it will perform all other duties
of paying agent as set forth in this Indenture.

 

(b) If the Company shall act as its own
paying agent with respect to any series of the Securities, it will on or before each due date of the principal of (and premium, if any)
or interest on Securities of that series, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay such principal (and premium, if any) or interest so becoming due on Securities of that series until such sums shall
be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of such action, or any failure
(by it or any other obligor on such Securities) to take such action. Whenever the Company shall have one or more paying agents for any
series of Securities, it will, prior to each due date of the principal of (and premium, if any) or interest on any Securities of that
series, deposit with the paying agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum

pay, or direct any paying agent to pay, to the Trustee all sums held in trust by the Company or such paying agent, such sums to be held
by the Trustee upon the same terms and conditions as those upon which such sums were held by the Company or such paying agent; and, upon
such payment by the Company or any paying agent to the Trustee, the Company or such paying agent shall be released from all further liability
with respect to such money.

 

Section 4.04 Appointment to Fill Vacancy in Office of Trustee.

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
ON EVENT OF DEFAULT

 

Section 6.01 Events of Default.

 

(a) Whenever used herein with respect to
Securities of a particular series, “Event of Default” means any one or more of the following events that has occurred and
is continuing:

 

(1) the Company defaults in the payment of
any installment of interest upon any of the Securities of that series, as and when the same shall become due and payable, and such default
continues for a period of 30 days; provided, however, that a valid extension of an interest payment period by the Company in accordance
with the terms of any indenture supplemental hereto shall not constitute a default in the payment of interest for this purpose;

 

(2) the Company defaults in the payment of
the principal of (or premium, if any, on) any of the Securities of that series as and when the same shall become due and payable whether
at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with
respect to that series; provided, however, that a valid extension of the maturity of such Securities in accordance with the terms of any
indenture supplemental hereto shall not constitute a default in the payment of principal or premium, if any;

 

(3) the Company fails to observe or perform
any other of its covenants or agreements with respect to that series contained in this Indenture or otherwise established with respect
to that series of Securities pursuant to Section 2.01 hereof (other than a covenant or agreement that has been expressly included in this
Indenture solely for the benefit of one or more series of Securities other than such series) for a period of 90 days after the date on
which written notice of such failure, requiring the same to be remedied and stating that such notice is a “Notice of Default”
hereunder, shall have been given to the Company by the Trustee, by registered or certified mail, or to the Company and the Trustee by
the holders of at least 25% in principal amount of the Securities of that series at the time Outstanding;

 

(4) the Company pursuant to or within the
meaning of any Bankruptcy Law (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary
case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property or (iv) makes a general assignment
for the benefit of its creditors; or

 

(5) a court of competent jurisdiction enters
an order under any Bankruptcy Law that (i) is for relief against the Company in an involuntary case, (ii) appoints a Custodian of the
Company for all or substantially all of its property or (iii) orders the liquidation of the Company, and the order or decree remains unstayed
and in effect for 90 days.

 

(b) In each and every such case (other than
an Event of Default specified in clause (4) or clause (5) above), unless the principal of all the Securities of that series shall have
already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Securities
of that series then Outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by such Securityholders),
may declare the principal of (and premium, if any, on) and accrued and unpaid interest on all the Securities of that series to be due
and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable. If an Event of
Default specified in clause (4) or clause (5) above occurs, the principal of and accrued and unpaid interest on all the Securities of
that series shall automatically be immediately due and payable without any declaration or other act on the part of the Trustee or the
holders of the Securities.

 

    15

     

    

 

(c) At any time after the principal of (and
premium, if any, on) and accrued and unpaid interest on the Securities of that series shall have been so declared due and payable, and
before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the holders
of a majority in aggregate principal amount of the Securities of that series then Outstanding hereunder, by written notice to the Company
and the Trustee, may rescind and annul such declaration and its consequences if: (i) the Company has paid or deposited with the Trustee
a sum sufficient to pay all matured installments of interest upon all the Securities of that series and the principal of (and premium,
if any, on) any and all Securities of that series that shall have become due otherwise than by acceleration (with interest upon such principal
and premium, if any, and, to the extent that such payment is enforceable under applicable law, upon overdue installments of interest,
at the rate per annum expressed in the Securities of that series to the date of such payment or deposit) and the amount payable to the
Trustee under Section 7.06, and (ii) any and all Events of Default under the Indenture with respect to such series, other than the nonpayment
of principal on (and premium, if any, on) and accrued and unpaid interest on Securities of that series that shall not have become due
by their terms, shall have been remedied or waived as provided in Section 6.06.

 

No such rescission and annulment shall extend to or shall affect any
subsequent default or impair any right consequent thereon.

 

(d) In case the Trustee shall have proceeded
to enforce any right with respect to Securities of that series under this Indenture and such proceedings shall have been discontinued
or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then
and in every such case, subject to any determination in such proceedings, the Company and the Trustee shall be restored respectively to
their former positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though
no such proceedings had been taken.

 

Section 6.02 Collection of Indebtedness and Suits for Enforcement
by Trustee.

 

(a) The Company covenants that (i) in case
it shall default in the payment of any installment of interest on any of the Securities of a series, or in any payment required by any
sinking or analogous fund established with respect to that series as and when the same shall have become due and payable, and such default
shall have continued for a period of 90 Business Days, or (ii) in case it shall default in the payment of the principal of (or premium,
if any, on) any of the Securities of a series when the same shall have become due and payable, whether upon maturity of the Securities
of a series or upon redemption or upon declaration or otherwise then, upon demand of the Trustee, the Company will pay to the Trustee,
for the benefit of the holders of the Securities of that series, the whole amount that then shall have been become due and payable on
all such Securities for principal (and premium, if any) or interest, or both, as the case may be, with interest upon the overdue principal
(and premium, if any) and (to the extent that payment of such interest is enforceable under applicable law) upon overdue installments
of interest at the rate per annum expressed in the Securities of that series; and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee under Section 7.06.

 

(b) If the Company shall fail to pay such
amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to
institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action
or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or other obligor upon
the Securities of that series and collect the moneys adjudged or decreed to be payable in the manner provided by law or equity out of
the property of the Company or other obligor upon the Securities of that series, wherever situated.

 

(c) In case of any receivership,
insolvency, liquidation, bankruptcy, reorganization, readjustment, arrangement, composition or judicial proceedings affecting the
Company, or its creditors or property, the Trustee shall have power to intervene in such proceedings and take any action therein
that may be permitted by the court and shall (except as may be otherwise provided by law) be entitled to file such proofs of claim
and other papers and documents as may be necessary or advisable in order to have the claims of the Trustee and of the holders of
Securities of such series allowed for the entire amount due and payable by the Company under the Indenture at the date of
institution of such proceedings and for any additional amount that may become due and payable by the Company after such date, and to
collect and receive any moneys or other property payable or deliverable on any such claim, and to distribute the same after the
deduction of the amount payable to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the holders of Securities of such series to make such payments to the Trustee, and,
in the event that the Trustee shall consent to the making of such payments directly to such Securityholders, to pay to the Trustee
any amount due it under Section 7.06.

 

    16

     

    

 

(d) All rights of action and of asserting
claims under this Indenture, or under any of the terms established with respect to Securities of that series, may be enforced by the Trustee
without the possession of any of such Securities, or the production thereof at any trial or other proceeding relative thereto, and any
such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for payment to the Trustee of any amounts due under Section 7.06, be for the ratable benefit of the holders
of the Securities of such series.

 

In case of an Event of Default hereunder, the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in this Indenture,
or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. Nothing contained herein shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Securityholder any plan of reorganization,

respect to the Securities of such series specifying such Event of Default, as hereinbefore provided; (ii) the holders of not less
than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the
Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; (iii) such holder or holders shall have
offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred
therein or thereby; (iv) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have failed
to institute any such action, suit or proceeding and (v) during such 60 day period, the holders of a majority in principal amount of

    17

     

    

 

Notwithstanding anything contained herein to the contrary or any other
provisions of this Indenture, the right of any holder of any Security to receive payment of the principal of (and premium, if any) and
interest on such Security, as therein provided, on or after the respective due dates expressed in such Security (or in the case of redemption,
on the redemption date), or to institute suit for the enforcement of any such payment on or after such respective dates or redemption
date, shall not be impaired or affected without the consent of such holder and by accepting a Security hereunder it is expressly understood,
intended and covenanted by the taker and holder of every Security of such series with every other such taker and holder and the Trustee,
that no one or more holders of Securities of such series shall have any right in any manner whatsoever by virtue or by availing of any
provision of this Indenture to affect, disturb or prejudice the rights of the holders of any other of such Securities, or to obtain or
seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner
herein provided and for the equal, ratable and common benefit of all holders of Securities of such series. For the protection and enforcement
of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can be given either
at law or in equity.

 

Section 6.05 Rights and Remedies Cumulative; Delay or Omission Not
Waiver.

 

(a) Except as otherwise provided in Section
2.07, all powers and remedies given by this Article to the Trustee or to the Securityholders shall, to the extent permitted by law, be
deemed cumulative and not exclusive of any other powers and remedies available to the Trustee or the holders of the Securities, by judicial
proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture or otherwise
established with respect to such Securities.

 

(b) No delay or omission of the Trustee
or of any holder of any of the Securities to exercise any right or power accruing upon any Event of Default occurring and continuing as
aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and,
subject to the provisions of Section 6.04, every power and remedy given by this Article or by law to the Trustee or the Securityholders
may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Securityholders.

 

Section 6.06 Control by Securityholders.

 

The holders of a majority in aggregate principal amount of the Securities
of any series at the time Outstanding, determined in accordance with Section 8.04, shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee
with respect to such series; provided, however, that such direction shall not be in conflict with any rule of law or with this Indenture.
Subject to the provisions of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in
good faith shall, by a Responsible Officer or officers of the Trustee, determine that the proceeding so directed, subject to the Trustee’s
duties under the Trust Indenture Act, would involve the Trustee in personal liability or might be unduly prejudicial to the Securityholders
not involved in the proceeding. The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding
affected thereby, determined in accordance with Section 8.04, may on behalf of the holders of all of the Securities of such series waive
any past default in the performance of any of the covenants contained herein or established pursuant to Section 2.01 with respect to such
series and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on, any of the Securities
of that series as and when the same shall become due by the terms of such Securities otherwise than by acceleration (unless such default
has been cured and a sum sufficient to pay all matured installments of interest and principal and any premium has been deposited with
the Trustee (in accordance with Section 6.01(c)). Upon any such waiver, the default covered thereby shall be deemed to be cured for all
purposes of this Indenture and the Company, the Trustee and the holders of the Securities of such series shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent
thereon.

 

    18

     

    

 

Section 6.07 Undertaking to Pay Costs.

 

All parties to this Indenture agree, and each holder of any Securities
by such holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it
as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not
apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of Securityholders, holding more than
10% in aggregate principal amount of the Outstanding Securities of any series, or to any suit instituted by any Securityholder for the
enforcement of the payment of the principal of (or premium, if any) or interest on any Security of such series, on or after the respective
due dates expressed in such Security or established pursuant to this Indenture.

 

ARTICLE 7

CONCERNING THE TRUSTEE

 

Section 7.01 Certain Duties and Responsibilities of Trustee.

 

(a) The Trustee, prior to the occurrence
of an Event of Default with respect to the Securities of a series and after the curing of all Events of Default with respect to the Securities
of that series that may have occurred, shall undertake to perform with respect to the Securities of such series such duties and only such
duties as are specifically set forth in this Indenture, and no implied covenants shall be read into this Indenture against the Trustee.
In case an Event of Default with respect to the Securities of a series has occurred (that has not been cured or waived), the Trustee shall
exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture, and use the same degree
of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

 

(b) No provision of this Indenture shall
be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

 

(i) prior to the occurrence of an Event of
Default with respect to the Securities of a series and after the curing or waiving of all such Events of Default with respect to that
series that may have occurred:

 

(A) the duties and obligations of the Trustee
shall with respect to the Securities of such series be determined solely by the express provisions of this Indenture, and the Trustee
shall not be liable with respect to the Securities of such series except for the performance of such duties and obligations as are specifically
set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

 

(B) in the absence of bad faith on the part
of the Trustee, the Trustee may with respect to the Securities of such series conclusively rely, as to the truth of the statements and
the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements
of this Indenture; but in the case of any such certificates or opinions that by any provision hereof are specifically required to be furnished
to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirement of this
Indenture;

 

(ii) the Trustee shall not be liable for any
error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the
Trustee was negligent in ascertaining the pertinent facts;

 

(iii) the Trustee shall not be liable
with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not
less than a majority in principal amount of the Securities of any series at the time Outstanding relating to the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee under this Indenture with respect to the Securities of that series; and

 

    19

     

    

 

(iv) None of the provisions contained in this
Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance
of any of its duties or in the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment
of such funds or liability is not reasonably assured to it under the terms of this Indenture or adequate indemnity against such risk is
not reasonably assured to it.

 

Section 7.02 Certain Rights of Trustee.

 

Except as otherwise provided in Section 7.01:

 

(a) The Trustee may rely conclusively and
shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond, security or other paper or document believed by it to be genuine and to have been signed or presented
by the proper party or parties;

 

(b) Any request, direction, order or demand
of the Company mentioned herein shall be sufficiently evidenced by a Board Resolution or an instrument signed in the name of the Company
by any authorized officer of the Company (unless other evidence in respect thereof is specifically prescribed herein);

 

(c) The Trustee may consult with counsel
and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of
any action taken or suffered or omitted hereunder in good faith and in reliance thereon;

 

(d) The Trustee shall be under no obligation
to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Securityholders
pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities that may be incurred therein or thereby; nothing contained herein shall, however, relieve
the Trustee of the obligation, upon the occurrence of an Event of Default with respect to a series of the Securities (that has not been
cured or waived), to exercise with respect to Securities of that series such of the rights and powers vested in it by this Indenture,
and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs;

 

(e) The Trustee shall not be liable for
any action taken or omitted to be taken by it in good faith and believed by it to be authorized or within the discretion or rights or
powers conferred upon it by this Indenture;

 

(f) The Trustee shall not be bound to make
any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request,
consent, order, approval, bond, security, or other papers or documents, unless requested in writing so to do by the holders of not less
than a majority in principal amount of the Outstanding Securities of the particular series affected thereby (determined as provided in
Section 8.04); provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely
to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such costs, expenses or liabilities
as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the Company or, if paid by the Trustee,
shall be repaid by the Company upon demand; and

 

(g) The Trustee may execute any of the trusts
or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.

 

In addition, the Trustee shall not be deemed to have knowledge of
any Default or Event of Default except (1) any Event of Default occurring pursuant to Sections 6.01(a)(1), 6.01(a)(2) and 4.01
hereof or (2) any Default or Event of Default of which the Trustee shall have received written notification in the manner set forth
in this Indenture or a Responsible Officer of the Trustee shall have obtained actual knowledge. Delivery of reports, information and
documents to the Trustee under Section 5.03 is for informational purposes only and the information and the Trustee’s receipt
of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information
contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee is
entitled to rely conclusively on an Officers’ Certificate).

 

    20

     

    

 

Section 7.03 Trustee Not Responsible for Recitals or Issuance or
Securities.

the Securities shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same.

 

(b) The Trustee makes no representations
as to the validity or sufficiency of this Indenture or of the Securities.

 

(c) The Trustee shall not be accountable
for the use or application by the Company of any of the Securities or of the proceeds of such Securities, or for the use or application
of any moneys paid over by the Trustee in accordance with any provision of this Indenture or established pursuant to Section 2.01, or
for the use or application of any moneys received by any paying agent other than the Trustee.

 

Section 7.04 May Hold Securities.

 

The Trustee or any paying agent or Security Registrar, in its individual
or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not Trustee, paying
agent or Security Registrar.

 

Section 7.05 Moneys Held in Trust.

 

Subject to the provisions of Section 11.05, all moneys received by
the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need
not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any moneys
received by it hereunder except such as it may agree with the Company to pay thereon.

 

Section 7.06 Compensation and Reimbursement.

 

(a) The Company covenants and agrees to
pay to the Trustee, and the Trustee shall be entitled to, such reasonable compensation (which shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust) as the Company and the Trustee may from time to time agree in writing,
for all services rendered by it in the execution of the trusts hereby created and in the exercise and performance of any of the powers
and duties hereunder of the Trustee, and, except as otherwise expressly provided herein, the Company will pay or reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the
provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons
not regularly in its employ), except any such expense, disbursement or advance as may arise from its negligence or bad faith and except
as the Company and Trustee may from time to time agree in writing. The Company also covenants to indemnify the Trustee (and its officers,
agents, directors and employees) for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad
faith on the part of the Trustee and arising out of or in connection with the acceptance or administration of this trust, including the
reasonable costs and expenses of defending itself against any claim of liability in the premises.

 

(b) The obligations of the Company under
this Section to compensate and indemnify the Trustee and to pay or reimburse the Trustee for reasonable expenses, disbursements and advances
shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior to that of the Securities
upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular
Securities.

 

    21

     

    

 

 

Section 7.07 Reliance on Officers’ Certificate.

 

Except as otherwise provided in Section 7.01, whenever in the administration
of the provisions of this Indenture the Trustee shall deem it reasonably necessary or desirable that a matter be proved or established
prior to taking or suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved
and established by an Officers’ Certificate delivered to the Trustee and such certificate, in the absence of negligence or bad faith
on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted to be taken by it under the
provisions of this Indenture upon the faith thereof.

 

Section 7.08 Disqualification; Conflicting Interests.

 

If the Trustee has or shall acquire any “conflicting interest”
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the Company shall in all respects comply with the provisions
of Section 310(b) of the Trust Indenture Act.

 

Section 7.09 Corporate Trustee Required; Eligibility.

 

There shall at all times be a Trustee with respect to the Securities
issued hereunder which shall at all times be a corporation organized and doing business under the laws of the United States of America
or any state or territory thereof or of the District of Columbia, or a corporation or other Person permitted to act as trustee by the
Securities and Exchange Commission, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus
of at least fifty million U.S. dollars ($50,000,000), and subject to supervision or examination by federal, state, territorial, or District
of Columbia authority.

 

If such corporation or other Person publishes reports of condition
at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such corporation or other Person shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. The Company may not, nor may any Person directly or indirectly controlling,
controlled by, or under common control with the Company, serve as Trustee. In case at any time the Trustee shall cease to be eligible
in accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect specified in
Section 7.10.

 

Section 7.10 Resignation and Removal; Appointment of Successor.

 

(a) The Trustee or any successor hereafter
appointed may at any time resign with respect to the Securities of one or more series by giving written notice thereof to the Company
and by transmitting notice of resignation by mail, first class postage prepaid, to the Securityholders of such series, as their names
and addresses appear upon the Security Register.

 

Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee with respect to Securities of such series by written instrument, in duplicate, executed by order of the Board
of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor
trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to Securities
of such series, or any Securityholder of that series who has been a bona fide holder of a Security or Securities for at least six months
may on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court
may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

 

(b) In case at any time any one of the following
shall occur:

 

(i) the Trustee shall fail to comply with
the provisions of Section 7.08 after written request therefor by the Company or by any Securityholder who has been a bona fide holder
of a Security or Securities for at least six months; or

 

    22

     

    

 

(ii) the Trustee shall cease to be eligible
in accordance with the provisions of Section 7.09 and shall fail to resign after written request therefor by the Company or by any such
Securityholder; or

 

(iii) the Trustee shall become incapable of
acting, or shall be adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding, or a receiver of the Trustee or of
its property shall be appointed or consented to, or any public officer shall take charge or control of the Trustee or of its property
or affairs for the purpose of rehabilitation, conservation or liquidation; then, in any such case, the Company may remove the Trustee
with respect to all Securities and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of
Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or any Securityholder
who has been a bona fide holder of a Security or Securities for at least six months may, on behalf of that holder and all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such
court may thereupon after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

 

(c) The holders of a majority in aggregate
principal amount of the Securities of any series at the time Outstanding may at any time remove the Trustee with respect to such series
by so notifying the Trustee and the Company and may appoint a successor Trustee for such series with the consent of the Company.

 

(d) Any resignation or removal of the Trustee
and appointment of a successor trustee with respect to the Securities of a series pursuant to any of the provisions of this Section shall
become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11.

 

(e) Any successor trustee appointed pursuant
to this Section may be appointed with respect to the Securities of one or more series or all of such series, and at any time there shall
be only one Trustee with respect to the Securities of any particular series.

 

Section 7.11 Acceptance of Appointment By Successor.

 

(a) In case of the appointment hereunder
of a successor trustee with respect to all Securities, every such successor trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor trustee all the rights, powers,
and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor trustee all property and money held by
such retiring Trustee hereunder.

 

    23

     

    

 

(b) In case of the appointment
hereunder of a successor trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor trustee with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor trustee shall accept such appointment and which (i) shall contain such provisions as
shall be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor
trustee relates, (ii) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts
hereunder administered by any other such Trustee and that no Trustee shall be responsible for any act or failure to act on the part
of any other Trustee hereunder; and upon the execution and delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall with respect to the Securities
of that or those series to which the appointment of such successor trustee relates have no further responsibility for the exercise
of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture, and each such
successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor trustee
relates; but, on request of the Company or any successor trustee, such retiring Trustee shall duly assign, transfer and deliver to
such successor trustee, to the extent contemplated by such supplemental indenture, the property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor trustee
relates.

 

(c) Upon request of any such successor trustee,
the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor trustee all
such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

 

(d) No successor trustee shall accept its
appointment unless at the time of such acceptance such successor trustee shall be qualified and eligible under this Article.

 

(e) Upon acceptance of appointment by a
successor trustee as provided in this Section, the Company shall transmit notice of the succession of such trustee hereunder by mail,
first class postage prepaid, to the Securityholders, as their names and addresses appear upon the Security Register. If the Company fails
to transmit such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such
notice to be transmitted at the expense of the Company.

 

Section 7.12 Merger, Conversion, Consolidation or Succession to
Business.

 

Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall
be a party, or any corporation succeeding to the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09,
without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated
with the same effect as if such successor Trustee had itself authenticated such Securities.

 

Section 7.13 Preferential Collection of Claims Against the Company.

 

The Trustee shall comply with Section 311(a) of the Trust Indenture
Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed
shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein.

 

Section 7.14 Notice of Default

 

If any Default or any Event of Default occurs and is continuing and
if such Default or Event of Default is known to a Responsible Officer of the Trustee, the Trustee shall mail to each Securityholder in
the manner and to the extent provided in Section 313(c) of the Trust Indenture Act notice of the Default or Event of Default within 90
days after it occurs and becomes known to the Trustee, unless such Default or Event of Default has been cured; provided, however,
that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on any Security, the Trustee
shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of
the Securityholders.

ARTICLE 8

CONCERNING THE SECURITYHOLDERS

 

Section 8.01 Evidence of Action by Securityholders.

 

Whenever in this Indenture it is provided that the holders of a majority
or specified percentage in aggregate principal amount of the Securities of a particular series may take any action (including the making
of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of
taking any such action the holders of such majority or specified percentage of that series have joined therein may be evidenced by any
instrument or any number of instruments of similar tenor executed by such holders of Securities of that series in person or by agent or
proxy appointed in writing.

 

If the Company shall solicit from the Securityholders of any series
any request, demand, authorization, direction, notice, consent, waiver or other action, the Company may, at its option, as evidenced by
an Officers’ Certificate, fix in advance a record date for such series for the determination of Securityholders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do
so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the close of business on the record date shall be deemed to
be Securityholders for the purposes of determining whether Securityholders of the requisite proportion of Outstanding Securities of that
series have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action,
and for that purpose the Outstanding Securities of that series shall be computed as of the record date; provided, however, that no such
authorization, agreement or consent by such Securityholders on the record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than six months after the record date.

 

Section 8.02 Proof of Execution by Securityholders.

 

Subject to the provisions of Section 7.01, proof of the execution of
any instrument by a Securityholder (such proof will not require notarization) or his agent or proxy and proof of the holding by any Person
of any of the Securities shall be sufficient if made in the following manner:

 

(a) The fact and date of the execution by
any such Person of any instrument may be proved in any reasonable manner acceptable to the Trustee.

 

(b) The ownership of Securities shall be
proved by the Security Register of such Securities or by a certificate of the Security Registrar thereof.

 

The Trustee may require such additional proof of any matter referred
to in this Section as it shall deem necessary.

 

Section 8.03 Who May be Deemed Owners.

 

Prior to the due presentment for registration of transfer of any Security,
the Company, the Trustee, any paying agent and any Security Registrar may deem and treat the Person in whose name such Security shall
be registered upon the books of the Company as the absolute owner of such Security (whether or not such Security shall be overdue and
notwithstanding any notice of ownership or writing thereon made by anyone other than the Security Registrar) for the purpose of receiving
payment of or on account of the principal of, premium, if any, and (subject to Section 2.03) interest on such Security and for all other
purposes; and neither the Company nor the Trustee nor any paying agent nor any Security Registrar shall be affected by any notice to the
contrary.

 

Section 8.04 Certain Securities Owned by Company Disregarded.

 

In determining whether the holders of the requisite aggregate
principal amount of Securities of a particular series have concurred in any direction, consent or waiver under this Indenture, the
Securities of that series that are owned by the Company or any other obligor on the Securities of that series or by any Person
directly or indirectly controlling or controlled by or under common control with the Company or any other obligor on the Securities
of that series shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the
purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Securities
of such series that the Trustee actually knows are so owned shall be so disregarded. The Securities so owned that have been pledged
in good faith may be regarded as Outstanding for the purposes of this Section, if the pledgee shall establish to the satisfaction of
the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not a Person directly or
indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In
case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the
Trustee.

 

    25

     

    

 

Section 8.05 Actions Binding on Future Securityholders.

 

At any time prior to (but not after) the evidencing to the Trustee,
as provided in Section 8.01, of the taking of any action by the holders of the majority or percentage in aggregate principal amount of
the Securities of a particular series specified in this Indenture in connection with such action, any holder of a Security of that series
that is shown by the evidence to be included in the Securities the holders of which have consented to such action may, by filing written
notice with the Trustee, and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Security. Except
as aforesaid any such action taken by the holder of any Security shall be conclusive and binding upon such holder and upon all future
holders and owners of such Security, and of any Security issued in exchange therefor, on registration of transfer thereof or in place
thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the holders of
the majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and the holders of all the Securities of that series.

of which are required to consent to any such supplemental indenture.

 

It shall not be necessary for the consent of the Securityholders of
any series affected thereby under this Section to approve the particular form of any proposed supplemental indenture, but it shall be
sufficient if such consent shall approve the substance thereof.

 

Section 9.03 Effect of Supplemental Indentures.

 

Upon the execution of any supplemental indenture pursuant to the provisions
of this Article or of Section 10.01, this Indenture shall, with respect to such series, be and be deemed to be modified and amended in

Securities of any series affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article or of
Section 10.01, may bear a notation in form approved by the Company, provided such form meets the requirements of any securities
exchange upon which such series may be listed, as to any matter provided for in such supplemental indenture. If the Company shall so
determine, new Securities of that series so modified as to conform, in the opinion of the Board of Directors, to any modification of
this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and
delivered in exchange for the Securities of that series then Outstanding.

Section 9.05 Execution of Supplemental Indentures.

 

Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders
required to consent thereto as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless
such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. The Trustee, subject to the provisions
of Section 7.01, will be entitled to receive and will be fully protected in relying upon an Officers’ Certificate and an Opinion
of Counsel stating that any supplemental indenture executed pursuant to this Article is authorized or permitted by, and conforms to, the
terms of this Article and that it is proper for the Trustee under the provisions of this Article to join in the execution thereof; provided,
however, that such Officers’ Certificate or Opinion of Counsel need not be provided in connection with the execution of a supplemental
indenture that establishes the terms of a series of Securities pursuant to Section 2.01 hereof.

 

Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee shall transmit by mail, first class postage prepaid, a
notice, setting forth in general terms the substance of such supplemental indenture, to the Securityholders of all series affected thereby
as their names and addresses appear upon the Security Register. Any failure of the Trustee to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such supplemental indenture.

acquires by conveyance or transfer, or which leases, the properties and assets of the Company substantially as an entirety shall expressly
assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual
payment of the principal of and any premium and interest on all the Securities and the performance or observance of every covenant of

been merged or by the Person which shall have acquired the Company’s assets; (b) immediately after giving effect to such transaction
and treating any indebtedness which becomes an obligation of the Company or any Subsidiary as a result of such transaction as having been
incurred by the Company or such Subsidiary at the time of such transaction, no Event of Default, and no event which, after notice or lapse

been named as the Company herein, and thereupon the predecessor corporation shall be relieved of all obligations and covenants under this
Indenture and the Securities.

(whether or not affiliated with the Company).

 

Section 10.03 Evidence of Consolidation, Etc. to Trustee.

 

The Trustee, subject to the provisions of Section 7.01, may receive

other shorter period set forth in applicable escheat or abandoned or unclaimed property law, shall be repaid to the Company on May 31
of each year or upon the Company’s request or (if then held by the Company) shall be discharged from such trust; and thereupon the
