Exhibit 10.1

PERFORMANCE-BASED RESTRICTED STOCK UNIT AGREEMENT (2022)

This Restricted Stock Unit Agreement (this “Agreement”), dated as of _____, 2022 (the “Grant Date”), is made by and between Sunstone Hotel Investors, Inc., a Maryland corporation (the “Company”), and __________________________ (the “Participant”). Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Plan (as defined below).

WHEREAS, the Company maintains the Sunstone Hotel Investors, Inc. 2004 Long-Term Incentive Plan (as amended from time to time, the “Plan”);

WHEREAS, the Company wishes to carry out the Plan (the terms of which are hereby incorporated by reference and made a part of this Agreement);

WHEREAS, Section 3.8 of the Plan provides for the issuance of restricted stock units (“RSUs”); and

WHEREAS, the Committee has determined that it would be to the advantage and in the best interest of the Company to issue RSUs to the Participant as an inducement to enter into or remain in the service of the Company or any Related Entity, and as an additional incentive during such service, and has advised the Company thereof.

NOW, THEREFORE, in consideration of the mutual covenants herein contained and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto do hereby agree as follows:

1.Issuance of Award of RSUs. Pursuant to the Plan, in consideration of the Participant’s agreement to provide services to the Company or any Related Entity (as applicable), the Company hereby issues to the Participant an award of ___________________RSUs. Each RSU that vests (and ceases to be subject to the Restrictions) shall represent the right to receive payment, in accordance with this Agreement, of one share of Common Stock. Unless and until an RSU vests, the Participant will have no right to payment in respect of any such RSU. Prior to actual payment in respect of any vested RSU, such RSU will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

2.Dividend Equivalents. Each RSU granted hereunder that becomes a Performance Vested RSU is hereby granted in tandem with a corresponding dividend equivalent right (a “Dividend Equivalent”), which Dividend Equivalent shall remain outstanding from the Grant Date until the earlier of the payment or forfeiture of the RSU to which it corresponds. Pursuant to each outstanding Dividend Equivalent, with respect to each dividend paid by the Company with respect to the Performance Period, the Participant shall be entitled to receive payment equal to the amount of such dividend, if any, on the Shares underlying the Performance Vested RSU to which such Dividend Equivalent relates, payable in the same form and amounts as dividends paid to each holder of a Share. Each such payment shall be made no later than thirty (30) days following the applicable dividend payment date, provided that no such payments shall be made prior to the date on which the RSU becomes a Performance Vested RSU, and any Dividend Equivalent payments that would have been made prior to such date had the RSU been a Performance Vested RSU, plus (or minus) the amount of gain (or loss) on such amounts had they been reinvested in Common Stock on the date on which the corresponding dividend was paid (at a price equal to the closing price of the Common Stock on the applicable dividend payment date), shall be paid in a single lump sum no later than forty-five (45) days following the date on which the RSU becomes a Performance Vested RSU. Dividend Equivalents shall not entitle the Participant to any payments relating to dividends for which the record date occurs after the payment of the Performance Vested RSU underlying such Dividend Equivalent, and

the Participant shall not be entitled to any Dividend Equivalent payments with respect to any RSU that does not become a Performance Vested RSU. Dividend Equivalents and any amounts that may become distributable in respect thereof shall be treated separately from the RSUs and the rights arising in connection therewith for purposes of the designation of time and form of payments required by Section 409A of the Code.

3.Definitions. For purposes of this Agreement, the following terms shall have the meanings set forth below.

The Company TSR Percentage shall be calculated in accordance with the total shareholder return calculation methodology used in the FTSE Nareit Lodging/Resort Index (and, for the avoidance of doubt, assuming the reinvestment of all dividends paid on Common Stock); provided, however, that for purposes of calculating total shareholder return for any Performance Period, the initial share price shall equal the closing price of a Share on the principal securities exchange on which such shares are then traded on the first trading day occurring within the Performance Period, and the final share price as of any given date shall be equal to the Share Value.

(b)Without limiting the foregoing, the RSUs and Common Stock issuable with respect thereto shall be subject to the restrictions on ownership and transfer set forth in the charter of the Company, as amended and supplemented from time to time.

5.Vesting.

(a)Performance Vesting. As soon as reasonably practicable (but in no event more than forty-five (45) days) following the completion of the Performance Period, the Committee shall determine the Company TSR Percentage, the Index TSR Percentages, the Index Relative Performance, the Relative TSR Performance Vesting Percentage and the number of RSUs granted hereby that have become Performance Vested RSUs, in each case as of the completion of the Performance Period. Subject to Sections 5(b) and 6(b) below, upon such determination by the Committee, the Restrictions set forth in Section 6(a) below applicable to any outstanding Performance Vested RSUs (if any) shall lapse and such Performance Vested RSUs shall become fully vested, subject to Participant’s continued status as a Service Provider through such vesting date. Any RSUs granted hereby which do not satisfy the requirements to become Performance Vested RSUs as of the completion of the Performance Period will automatically be cancelled and forfeited without payment of any consideration therefor, and the Participant shall have no further right to or interest in such RSUs.

(b)Change in Control. Notwithstanding the foregoing, in the event that (i) a Change in Control occurs prior to the completion of the Performance Period, (ii) the Participant has not incurred a Termination of Employment prior to such Change in Control and (iii) this award of RSUs is not continued, converted, assumed or replaced by the surviving or successor entity in such Change in Control in an equitable manner approved by the Administrator in good faith, the Restrictions shall lapse with respect to a number of RSUs equal to the number of RSUs which would be Performance Vested RSUs (if any) based on actual performance as of and assuming the completion of the Performance Period as of the date of the Change in Control, and such RSUs shall, immediately prior to such Change in Control, become fully vested and shall be deemed to be Performance Vested RSUs. Any RSUs that do not become fully vested in accordance with the

preceding sentence will automatically be cancelled and forfeited as of the date of the Change in Control without payment of any consideration therefor, and the Participant shall have no further right to or interest in such RSUs. The Participant acknowledges and agrees that the accelerated vesting provision contained in Section 4(a)(ii)(B) of the Employment Agreement is superseded by this Agreement, such that such accelerated vesting provision shall not apply with respect to the RSUs granted pursuant to this Agreement.

6.Effect of Termination of Employment.

(a)Termination of Employment. Subject to Section 6(b) below, in the event of the Participant’s Termination of Employment for any reason, any and all Unvested RSUs as of the date of such Termination of Employment (after taking into account any accelerated vesting that occurs in connection with such termination) will automatically and without further action be cancelled and forfeited without payment of any consideration therefor, and the Participant shall have no further right to or interest in such Unvested RSUs. Subject to Section 6(b) below, no RSUs which have not vested as of the date of the Participant’s Termination of Employment shall thereafter become vested.

(b)Qualifying Termination. In the event that the Participant incurs a Qualifying Termination prior to the completion of the Performance Period, the Restrictions shall lapse with respect to a number of RSUs equal to the product of (x) the number of RSUs which would be Performance Vested RSUs (if any) based on actual performance as of and assuming the completion of the Performance Period as of the date of the Participant’s Qualifying Termination, and (y) a fraction, the numerator of which is the number of days elapsed from the first day of the Performance Period through and including the date of the Participant’s Qualifying Termination, and the denominator of which is 1095 (the “Qualifying Termination RSUs”), and such RSUs shall become fully vested and shall be deemed to be Performance Vested RSUs upon the Committee’s determination, within forty-five (45) days following the date of the Participant’s Qualifying Termination, of the number of Qualifying Termination RSUs. Any RSUs that do not become fully vested in accordance with the preceding sentence will automatically be cancelled and forfeited as of the date of the Committee’s determination of the number of Qualifying Termination RSUs without payment of any consideration therefor, and the Participant shall have no further right to or interest in such RSUs. The Participant acknowledges and agrees that the accelerated vesting provision contained in Section 4(a)(ii)(B) of the Employment Agreement is superseded by this Agreement, such that such accelerated vesting provision shall not apply with respect to the RSUs granted pursuant to this Agreement.

7.Payment. Payments in respect of any RSUs that vest in accordance herewith shall be made to the Participant (or in the event of the Participant’s death, to his or her estate) in whole Shares, and any fractional Share will be rounded as determined by the Company; provided, however, that in no event shall the aggregate number of RSUs that vest or become payable hereunder exceed 200% of the total number of RSUs set forth in Section 1 of this Agreement. The Company shall make such payments as soon as practicable after the applicable vesting date, but in any event within twenty (20) days after such vesting date, provided that, in the event of vesting upon a Change in Control under Section 5(b) above, such payment shall be made or deemed made immediately preceding and effective upon the occurrence of such Change in Control.

8.Determinations by Committee. Notwithstanding anything contained herein, all determinations, interpretations and assumptions relating to the vesting of the RSUs (including, without limitation, determinations, interpretations and assumptions with respect to Company TSR Percentage and Index TSR Percentages) shall be made by the Committee and shall be applied consistently and uniformly to all similar Awards granted under the Plan. In making such determinations, the Committee may employ attorneys, consultants, accountants, appraisers, brokers, or other persons, and the Committee, the Board, the Company and their officers and directors shall be entitled to rely upon the advice, opinions or valuations of any such persons. All actions taken and all interpretations and determinations made by the Committee in good faith and absent manifest error shall be final and binding upon the Participant, the Company and all other interested persons. In addition, the Committee, in its

discretion, may adjust or modify the methodology for calculations relating to the vesting of the RSUs (including, without limitation, the methodology for calculating Company TSR Percentage and Index TSR Percentages), other than the Relative TSR Performance Vesting Percentage, as necessary or desirable to account for events affecting the value of the Common Stock which, in the discretion of the Committee, are not considered indicative of Company performance, which may include events such as the issuance of new Common Stock, stock repurchases, stock splits, issuances and/or exercises of stock grants or stock options, and similar events, all in order to properly reflect the Company’s intent with respect to the performance objectives underlying the RSUs or to prevent dilution or enlargement of the benefits or potential benefits intended to be made available with respect to the RSUs.

9.Restrictions on New RSUs or Shares. In the event that the RSUs or the Shares underlying the RSUs are changed into or exchanged for a different number or kind of securities of the Company or of another corporation or other entity by reason of merger, consolidation, recapitalization, reclassification, stock split, stock dividend or combination of shares, such new or additional or different securities which are issued upon conversion of or in exchange or substitution for RSUs or the Shares underlying the RSUs which are then subject to vesting shall be subject to the same vesting conditions as such RSUs or Shares, as applicable, unless the Committee provides for the vesting of the RSUs or the Shares underlying the RSUs, as applicable.

10.Conditions to Issuance of Shares. Shares issued as payment for the RSUs will be issued out of the Company’s authorized but unissued Shares. Upon issuance, such Shares shall be fully paid and nonassessable. The Shares issued pursuant to this Agreement shall be held in book-entry form and no certificates shall be issued therefor. In addition to the other requirements set forth herein, the Shares issued as payment for the RSUs shall be issued only upon the fulfillment of all of the following conditions:

(a)The admission of such Shares to listing on all stock exchanges on which such class of stock is then listed;

(b)The completion of any registration or other qualification of such shares under any state or federal law or under rulings or regulations of the Securities and Exchange Commission or of any other governmental regulatory body, which the Committee shall, in its absolute discretion, deem necessary or advisable;

(c)The obtaining of any approval or other clearance from any state or federal governmental agency which the Committee shall, in its absolute discretion, determine to be necessary or advisable;

(d)The lapse of such reasonable period of time as the Committee may from time to time establish for reasons of administrative convenience; and

(e)The receipt by the Company of full payment for any applicable withholding or other employment tax or required payments with respect to any such Shares to the Company with respect to the issuance or vesting of such Shares.

In the event that the Company delays a distribution or payment in settlement of RSUs because it reasonably determines that the issuance of Shares in settlement of RSUs will violate federal securities laws or other applicable law, such distribution or payment shall be made at the earliest date at which the Company reasonably determines that the making of such distribution or payment will not cause such violation, as required by Treasury Regulation Section 1.409A-2(b)(7)(ii). The Company shall not delay any payment if such delay will result in a violation of Section 409A of the Code.

11.Rights as Stockholder. Neither the Participant nor any person claiming under or through the Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until such Shares will have been issued, recorded on the records of the Company

or its transfer agents or registrars, and delivered to the Participant or any person claiming under or through the Participant.

12.Tax Withholding. The Company or any Related Entity shall have the authority and the right to deduct or withhold, or require the Participant to remit to such entity, an amount sufficient to satisfy federal, state, local and foreign taxes (including the Participant’s FICA obligation) required by law to be withheld with respect to the issuance, vesting or payment of the RSUs and the Dividend Equivalents. In satisfaction of the foregoing requirement or in satisfaction of any additional tax withholding, the Company or any Related Entity may, or the Committee may in its discretion allow the Participant to elect to have the Company or any Related Entity (as applicable), withhold Shares otherwise issuable under such award (or allow the return of Shares) having a Fair Market Value equal to the sums required to be withheld. Notwithstanding any other provision of the Plan or this Agreement, the number of Shares which may be withheld with respect to the issuance, vesting or payment of the RSUs and the Dividend Equivalents in order to satisfy the Participant’s income and payroll tax liabilities with respect thereto shall be limited to the number of shares which have a fair market value on the date of withholding no greater than the aggregate amount of such liabilities based on the maximum individual statutory withholding rates in the applicable jurisdiction.

13.Remedies. The Participant shall be liable to the Company for all costs and damages, including incidental and consequential damages, resulting from a disposition of the RSUs which is in violation of the provisions of this Agreement. Without limiting the generality of the foregoing, the Participant agrees that the Company shall be entitled to obtain specific performance of the obligations of the Participant under this Agreement and immediate injunctive relief in the event any action or proceeding is brought in equity to enforce the same. The Participant will not urge as a defense that there is an adequate remedy at law.

14.Restrictions on Public Sale by the Participant. To the extent not inconsistent with applicable law, the Participant agrees not to effect any sale or distribution of the RSUs or the Shares underlying the RSUs or any similar security of the Company, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during the fourteen (14) days prior to, and during the up to 90 day period beginning on, the date of the pricing of any public or private debt or equity securities offering by the Company (except as part of such offering), if and to the extent requested in writing by the Company in the case of a non-underwritten public or private offering or if and to the extent requested in writing by the managing underwriter or underwriters (or initial purchaser or initial purchasers, as the case may be) and consented to by the Company, which consent may be given or withheld in the Company’s sole and absolute discretion, in the case of an underwritten public or private offering (such agreement to be in the form of a lock-up agreement provided by the Company, managing underwriter or underwriters, or initial purchaser or initial purchasers, as the case may be).

15.Conformity to Securities Laws. The Participant acknowledges that the Plan and this Agreement are intended to conform to the extent necessary with all provisions of all applicable federal and state laws, rules and regulations (including, but not limited to the Securities Act of 1933 (the “Securities Act”) and the Exchange Act and any and all regulations and rules promulgated by the Securities and Exchange Commission thereunder, including without limitation the applicable exemptive conditions of Rule 16b-3 of the Exchange Act) and to such approvals by any listing, regulatory or other governmental authority as may, in the opinion of counsel for the Company, be necessary or advisable in connection therewith. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the RSUs are granted, only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by applicable law, the Plan, this Agreement and the RSUs shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.

16.Code Section 409A. To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the

effective date of this Agreement. Notwithstanding any provision of this Agreement to the contrary, in the event that following the effective date of this Agreement, the Company determines that the RSUs may be subject to Section 409A of the Code and related Department of Treasury guidance (including such Department of Treasury guidance as may be issued after the effective date of this Agreement ), the Company may adopt such amendments to this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect ), or take any other actions, that the Company determines are necessary or appropriate to (a) exempt the RSUs from Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the RSUs, or (b) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance; provided, however, that this Section 16 shall not create any obligation on the part of the Company or any Related Entity to adopt any such amendment, policy or procedure or take any such other action. For purposes of Section 409A of the Code, any right to a series of payments pursuant to this Agreement shall be treated as a right to a series of separate payments. Notwithstanding anything to the contrary in this Agreement, no amounts shall be paid to the Participant under this Agreement during the six-month period following the Participant’s “separation from service” to the extent that the Committee determines that the Participant is a “specified employee” (each within the meaning of Section 409A of the Code) at the time of such separation from service and that paying such amounts at the time or times indicated in this Agreement would be a prohibited distribution under Code Section 409A(a)(2)(b)(i). If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six-month period (or such earlier date upon which such amount can be paid under Section 409A of the Code without being subject to such additional taxes), the Company shall pay to the Participant in a lump-sum all amounts that would have otherwise been payable to the Participant during such six-month period under this Agreement.

17.No Right to Continued Service. Nothing in this Agreement shall confer upon the Participant any right to continue as a Service Provider of the Companyor any Related Entity, or shall interfere with or restrict in any way the rights of the Company or any Related Entity, which rights are hereby expressly reserved, to discharge the Participant at any time for any reason whatsoever, with or without cause.
