**Delaware** 

***Blackstone Inc.***

Blackstone Inc. is incorporated under the laws of Delaware.

Section 145 of the DGCL provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, in which such person is made a party by reason of the fact that the person is or was a director, officer, employee or agent of the corporation (other than an action by or in the right of the corporation, including a derivative action), if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person's conduct was unlawful. A similar standard is applicable in the case of an action by or in the right of the corporation, including any derivative action, except that indemnification only extends to expenses (including attorneys' fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification of expenses where the person seeking indemnification has been found liable to the corporation. Section 145 also provides that a corporation may pay expenses incurred by its directors and officers and other parties in defending against any action, suit or proceeding in advance of the final disposition of the action, suit or proceeding, subject to, in the case of any current director or officer, the provision of an undertaking to repay the amounts advanced in the event it is determined such director or officer is not entitled to be indemnified. The statute provides that it is not exclusive of other indemnification or other rights that may be granted by a corporation's bylaws, disinterested director vote, stockholder vote, agreement or otherwise.

------

Under our certificate of incorporation, in most circumstances we will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Series II Preferred Stockholder; (b) Blackstone Group Management L.L.C. (the "Former General Partner") in its capacity as the former general partner of The Blackstone Group L.P. (our entity form prior to our conversion to a corporation on July 1, 2019); (c) any person who is or was a controlling affiliate of the Series II Preferred Stockholder or the Former General Partner; (d) any person who is or was a director or an officer of Blackstone Inc., the Series II Preferred Stockholder or the Former General Partner; (e) any person in clause (d) who is or was serving at the request of Blackstone Inc., the Series II Preferred Stockholder or the Former General Partner as an officer, director, employee, member, partner, agent, fiduciary or trustee of another person; provided that a person shall not be an indemnitee by reason of providing, on a fee-for-services basis, trustee, fiduciary or custodial services; or (f) any person Blackstone Inc. in its sole discretion designates as an indemnitee. Under our certificate of incorporation, we are also required to advance the expenses incurred by such indemnitees in appearing at, participating in or defending any claim, demand, action, suit or proceeding prior to its final disposition upon (i) our receipt of an undertaking on behalf of the indemnitee to repay the amount if it is ultimately determined the indemnitee is not entitled to be indemnified and (ii) to the extent determined by our board of directors in its sole discretion to be necessary or advisable, our receipt of security or other assurances satisfactory to the board of directors in its sole discretion that the indemnitee will be able to repay such amount if it ultimately shall be determined that the indemnitee is not entitled to be indemnified as authorized.

Any indemnification under these provisions will only be out of our assets. Unless it otherwise agrees, the Series II Preferred Stockholder will not be personally liable for, or have any obligation to contribute or loan any monies or property to us to enable us to effectuate, such indemnification. The indemnification of the persons described above shall be in addition to any other any indemnification such person is entitled to the extent applicable. We may purchase insurance against liabilities asserted against and expenses incurred by persons in connection with its activities, regardless of whether we would have the power to indemnify the person against liabilities under our certificate of incorporation.

Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision that limits or eliminates the liability of its directors and officers for monetary damages to the corporation and its stockholders for breach of fiduciary duty. However, no provision may limit or eliminate the liability of a director or officer for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any breach of the director's or officer's duty of loyalty to the corporation or its stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any act or omission not in good faith or which involved intentional misconduct or a knowing violation of law by a
director or officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any unlawful payment of dividends or unlawful stock repurchase or redemption;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any transaction from which the director or officer derived an improper personal benefit; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of an officer, any action by or in the right of the corporation (including any derivative claim)
against the officer.

Our certificate of incorporation provides that our directors shall not be liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL.

Section 145(g) of the DGCL authorizes a corporation to purchase and maintain insurance for its directors and officers and other persons. We currently maintain liability insurance for our directors and officers. Such insurance would be available to our directors and officers in accordance with its terms.

In any underwriting agreement we enter into in connection with the sale of the securities registered hereby, the underwriters may agree to indemnify, or contribute to, under certain conditions, us, our directors, our officers and persons who control us within the meaning of the Securities Act against certain liabilities.

***Blackstone Holdings III L.P. and Blackstone Holdings IV L.P.***

Each of Blackstone Holdings III L.P. and Blackstone Holdings IV L.P. is formed and organized under the laws of the Province of Québec.

The Civil Code of Québec provides that a partner of a Québec limited partnership is entitled to recover the amount of the disbursements it has made on behalf of the partnership and to be indemnified for the obligations it has contracted or the losses it has suffered in acting for the partnership if it was in good faith. No provision of the Civil Code of Québec precludes a partnership from reimbursing its general partner for costs, charges and expenses actually incurred in the performance of its duties thereunder, including costs, charges expenses directly incurred for the benefit of the partnership and costs incurred by the general partner in compensating its directors, officers and employees.

The limited partnership agreements of each of Blackstone Holdings III L.P. and Blackstone Holdings IV L.P. provides that the partnership shall indemnify, to the fullest extent permitted by law, any person (and such person's heirs, executors or administrators) who was or is made or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding (brought in the right of the partnership or otherwise), whether civil, criminal, administrative or investigative, and whether formal or informal, including appeals, by reason of the fact that such person, or a person for whom such person was the legal representative, is or was the general partner or a director or officer of the general partner or the partnership or, while a director or officer of the general partner or the partnership, is or was serving at the request of the partnership as a director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust, limited liability company, nonprofit entity or other enterprise, for and against all loss and liability suffered and expenses (including attorneys' fees), judgments, fines and amounts paid in settlement reasonably incurred by such person or such heirs, executors or administrators, except in cases of bad faith. The partnership must also pay expenses, to the fullest extent permitted by law, incurred in defending any proceeding in advance of its final disposition, upon (i) presentation of an undertaking on behalf of such indemnified person to repay such amount if it shall ultimately be determined that such indemnified person is not entitled to be indemnified and (ii) to the extent determined by the general partner in its sole discretion to be necessary or advisable, receipt by the partnership of security or other assurances satisfactory to the general partner in its sole discretion that such person will be able to repay such amount if it ultimately shall be determined that such person is not entitled to be indemnified.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this
registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in
volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus
filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the
effective registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the
registration statement or any material change to such information in the registration statement.

*Provided, however*, that Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 (15 U.S.C. 78m or 78o(d)) that are incorporated by reference in the registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which
remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the
registration statement as of the date the filed prospectus was deemed part of and included in the registration statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration
statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of
and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness

------

or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any
purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used
to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell
such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be
filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or
used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The portion of any other free writing prospectus relating to the offering containing material information about
the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the
Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering
of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to
directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will
be governed by the final adjudication of such issue.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The undersigned registrant hereby undertakes to file an application for the purpose of determining the
eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under section 305(b)(2) of the Trust Indenture Act.
