If the legal proceeding, however, is by or in the right of the Registrant, the director or officer (i) may be indemnified by the Registrant only for expenses (including attorneys&#8217; fees) but not for judgments, fines or amounts paid in settlements and (ii) may not be indemnified for expenses in respect of any claim, issue or matter as to which he or she shall have been adjudged to be liable to the Registrant unless a court determines otherwise.</p>

The Registrant&#8217;s restated certificate of incorporation also contains a provision that eliminates, subject to certain exceptions, to the fullest extent permitted by the Delaware General Corporation Law, the personal liability of each director of the Registrant to the Registrant and its stockholders for monetary damages for breaches of fiduciary duty as a director.</p>

Item 6.
Indemnification of Directors and Officers
.
The Registrant is a Delaware corporation subject to the applicable indemnification provisions of the General Corporation Law of the State of Delaware, which is referred to herein as the "Delaware General Corporation Law." Under Section 145 of the Delaware General Corporation Law, each director and officer of the Registrant may be indemnified by the Registrant against all expenses and liabilities (including attorney's fees, judgments, fines and amounts paid in settlement) actually or reasonably incurred in connection with the defense or settlement of any threatened, pending or completed legal proceedings (other than a proceeding by or in the right of the Registrant) in which he or she is involved by reason of the fact that he or she is or was a director or officer of the Registrant if such director or officer acted in good faith and in a manner that he or she reasonably believed to be in or not opposed to the best interests of the Registrant and, with respect to any criminal action or proceeding, if he or she had no reasonable cause to believe that his or her conduct was unlawful. If the legal proceeding, however, is by or in the right of the Registrant, the director or officer (i) may be indemnified by the Registrant only for expenses (including attorneys' fees) but not for judgments, fines or amounts paid in settlements and (ii) may not be indemnified for expenses in respect of any claim, issue or matter as to which he or she shall have been adjudged to be liable to the Registrant unless a court determines otherwise.
The Registrant's amended and restated bylaws and restated certificate of incorporation both provide for the indemnification of the Registrant's directors and officers, to the fullest extent permitted by the Delaware General Corporation Law, for all liability and loss (including attorney's fees) incurred in defending actions brought against them arising out of the performance of their duties. The Registrant's restated certificate of incorporation also contains a provision that eliminates, subject to certain exceptions, to the fullest extent permitted by the Delaware General Corporation Law, the personal liability of each director of the Registrant to the Registrant and its stockholders for monetary damages for breaches of fiduciary duty as a director.
The foregoing is only a general summary of certain aspects of Delaware law and the Registrant's restated certificate of incorporation and amended and restated bylaws dealing with indemnification of directors and officers and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of the Delaware General Corporation Law and the Registrant's restated certificate of incorporation and amended and restated bylaws.
The Registrant has entered into indemnification agreements with its directors and executive officers, and intends to enter into indemnification agreements with any new directors and executive officers in the future. Pursuant to such agreements, the Registrant will, to the extent permitted by applicable law, indemnify such persons against all expenses, judgments, fines and penalties incurred in connection with the defense or settlement of any actions brought against them by reason of the fact that they were directors or officers of the Registrant or assumed certain responsibilities at the direction of the Registrant. The preceding discussion of the Registrant's indemnification agreements is not intended to be exhaustive and is qualified in its entirety by reference to such indemnification agreements.
Under the 2021 Plan, each person who is or shall have been a member of the Registrant's board of directors, or a committee appointed by the Registrant's board of directors, or an officer of the Registrant to whom authority was delegated in accordance with the 2021 Plan shall be indemnified and held harmless by the Registrant against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the 2021 Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Registrant's approval, or paid by him or her in satisfaction of any judgment in any such action, suit, or proceeding against him or her, provided he or she shall give the Registrant an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf, unless such loss, cost, liability, or expense is a result of his or her own willful misconduct or except as expressly provided by statute.

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;
(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 a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and
5
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in th
e
Registration Statement or any material change to such information in th
e
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 periodic 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.
(h)
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.
