  might otherwise benefit the Registrant and its stockholders. A Registrant stockholder&#146;s investment may be adversely affected to the extent that, in a class action or direct suit, the Registrant pays the costs of settlement and damage awards
  against directors and officers pursuant to these indemnification provisions. However, these provisions will not limit or eliminate the Registrant&#146;s rights, or those of any Registrant stockholder, to

  Item 4. Description of Securities.
  Not applicable.
  Item 5. Interests of
  Named Experts and Counsel.
  Not applicable.
  Item 6. Indemnification of Directors and Officers.
  Maryland law permits the Registrant to include a provision in its charter (the "
  Charter
  ") eliminating the
  liability of its directors and officers to it and its stockholders for money damages, except for liability resulting from (1) actual receipt of an improper benefit or profit in money, property or services or (2) active and deliberate
  dishonesty that is established by a final judgment and is material to the cause of action. The Charter will contain a provision that eliminates the Registrant's directors' and officers' liability to it and its stockholders for money
  damages to the maximum extent permitted by Maryland law.
  The Maryland General Corporation Law (the "
  MGCL
  ") requires a
  corporation (unless its charter or bylaws provide otherwise, which the Charter will not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made or
  threatened to be made a party by reason of his or her service in that capacity and permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable
  expenses actually incurred by them in connection with any proceeding to or in which they may be made or threatened to be made a party or witness by reason of their service in those or other capacities unless it is established that:
  •
  the act or omission of the director or officer was material to the matter giving rise to the proceeding and
  (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty;
  •
  the director or officer actually received an improper personal benefit in money, property or services; or
  •
  in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or
  omission was unlawful.
  The MGCL prohibits the Registrant from indemnifying a director or officer who has been adjudged
  liable in a suit by the Registrant or on its behalf or in which the director or officer was adjudged liable on the basis that a personal benefit was improperly received. A court may order indemnification if it determines that the director or officer
  is fairly and reasonably entitled to indemnification, even though the director or officer did not meet the prescribed standard of conduct or was adjudged liable on the basis that personal benefit was improperly received; however, indemnification for
  an adverse judgment in a suit by the Registrant or on its behalf, or for a judgment of liability on the basis that personal benefit was improperly received, is limited to expenses.
  In addition, the MGCL permits a Maryland corporation to advance reasonable expenses to a director or officer upon receipt of (1) a
  written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification and (2) a written undertaking by him or her or on his or her behalf to repay the amount
  paid or reimbursed if it is ultimately determined that the standard of conduct was not met.
  The Charter obligates it to the maximum
  extent permitted by Maryland law in effect from time to time, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a
  proceeding to:
  •
  any present or former director or officer who is made or threatened to be made a party to, or witness in, a
  proceeding by reason of his or her service in that capacity; or
  •
  any individual who, while a director or officer of the Registrant and at its request, serves or has served as a
  director, officer, member, manager, partner or trustee of another corporation, real estate investment trust, limited liability company, partnership, joint venture, trust, employee benefit plan or any other enterprise and who is made or threatened to
  be made a party to, or witness in, the proceeding by reason of his or her service in that capacity.
  The Registrant expects to enter into indemnification agreements with its directors and
  certain officers which will provide for indemnification to the maximum extent permitted by Maryland law. The Registrant also expects to maintain a directors' and officers' insurance policy that will insure the directors and officers of the
  Registrant from claims arising out of an alleged wrongful act by such person in their respective capacities as directors and officers of the Registrant, subject to certain exceptions.
  The limitation of liability and indemnification provisions that will be in the Charter may discourage stockholders from bringing a lawsuit
  against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against the Registrant's directors and officers, even though such an action, if successful,
  might otherwise benefit the Registrant and its stockholders. A Registrant stockholder's investment may be adversely affected to the extent that, in a class action or direct suit, the Registrant pays the costs of settlement and damage awards
  against directors and officers pursuant to these indemnification provisions. However, these provisions will not limit or eliminate the Registrant's rights, or those of any Registrant stockholder, to
  seek non-monetary relief
  such as an injunction or rescission in the event of a breach of a director's fiduciary duties. The provisions will not alter the liability of directors under the federal
  securities laws.

  Item 9. Undertakings.
  (a) The undersigned Registrant hereby undertakes:
  (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration
  Statement:
  (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the
  "
  Securities Act
  ");
  (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 Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the
  "Calculation of Filing Fee Tables" or "Calculation of Registration Fee" table, as applicable, in the effective Registration Statement;
  (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) and (a)(1)(ii) 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 Commission by the Registrant pursuant to Section 13 or
  Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.
  (2) That, for the
  purpose of determining any liability under the Securities Act, 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.
  (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.
  (b) The
  undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and,
  where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) 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.
  (c) Insofar as indemnification for liabilities arising under the Securities Act 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 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 and will be
  governed by the final adjudication of such issue.
  SIGNATURES
  Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of
  the requirements for filing on Form
  S-8
  and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of New York, State of New York, on
  this 30th day of September, 2024.
