NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows:

Section 1. Steiner Directors.

(a) Upon the terms and subject to the conditions of this Agreement, from and after the Closing, the Company will take all necessary and desirable actions within its control (including calling meetings of the Company Board and the shareholders and recommending, supporting and soliciting proxies), such that:

(i) from and after the Closing and for so long as the SLL Investor Holders, in the aggregate, beneficially own at least 15.00% of the issued and outstanding Company Common Shares, the Majority SLL Investor Holders shall have the right, but not the obligation, to designate one individual to be appointed or nominated, as the case may be, as a Class B director of the Company Board and one individual to be appointed or nominated, as the case may be, as a Class C director of the Company Board, or if the Company Board does not contain classes, two (2) individuals to be appointed or nominated, as the case may be, as directors of the Company Board; and

(ii) from and after the time at which the ownership threshold set forth in clause (i) of this Section 1(a) is no longer satisfied and for so long as the SLL Investor Holders, in the aggregate, beneficially own at least 5.00% of the issued and outstanding Company Common Shares, the Majority SLL Investor Holders shall have the right, but not the obligation, to designate one individual to be appointed or nominated, as the case may be, as a Class B director or Class C director of the Company Board, or if the Company Board does not contain classes, as directors of the Company Board.

If the ownership threshold(s) set forth in clauses (i) and/or (ii) of this Section 1(a) is or are, as applicable, no longer satisfied, then the Steiner Representative shall, and shall cause each other SLL Investor Holder to, take all actions necessary and desirable within its control to cause the requisite number of Steiner Directors to, as promptly as practical thereafter (and in any event within five (5) Business Days), deliver a resignation letter to the Nominating Committee for purposes of this paragraph, determined based on the number of directors that would need to resign in order for the number of Steiner Directors to match the number of directors that the Majority SLL Investor Holders then have the right to designate pursuant to this Section 1(a); provided that if the ownership threshold set forth in clause (i) of this Section 1(a) is no longer satisfied prior to the end of the Non-Continuing Class C Director Term, then the Non-Continuing Class C Steiner Director shall (if then-serving as a director) be one of the Steiner Directors that submits his or her resignation to the Nominating Committee and, for the avoidance of doubt, one of the Specified Steiner Directors shall remain on the Company Board. The Majority SLL Investor Holders shall, in their sole discretion, determine which Steiner Directors will deliver his or her resignation as required pursuant to the immediately preceding sentence, and any such resignation delivered pursuant to the immediately preceding sentence must be either accepted or rejected by the Nominating Committee within ten (10) Business Days of receipt thereof (it being understood and agreed that (A) if the Nominating Committee does not accept such resignation within such ten (10) Business Day period, then, unless such resignation specifically states that it supersedes this proviso, the Nominating Committee shall be deemed to have rejected such resignation and (B) the Nominating Committee may accept such resignation, effective as of a later specified date or event, unless such resignation specifically states that it supersedes this proviso, is not conditioned on acceptance by the Nominating Committee, and will be effective immediately). For illustrative purposes only, if the SLL Investor Holders, in the aggregate, beneficially own 16% of the issued and outstanding Common Shares on the date that is nine (9) months after the date hereof and, immediately after giving effect to a transfer of Common Shares as of such date, would beneficially own 6% of the issued and outstanding Common Shares, then the Steiner Representative and the other SLL Investor Holders shall cause one (1) Specified Steiner Director and the Non-Continuing Class C Steiner Director to deliver a resignation letter as provided in this paragraph.

Notwithstanding anything to the contrary in this Agreement, the Investment Agreement or the Governing Documents of Company, subject to Section 1(d), neither the Company Board nor any other Person (other than the Majority SLL Investor Holders pursuant to this Section 1(c)) may appoint, elect or designate any Person to fill any such director position described in the preceding sentence. Notwithstanding anything to the contrary contained herein, the Company Board (and/or the Nominating Committee) shall determine in its sole discretion whether or not to nominate the individual (if any) then serving as the Non-Continuing Class C Steiner Director for re-election at the 2022 annual meeting of the Company’s shareholders; provided, that, for the avoidance of doubt, this sentence shall not limit or affect the Majority SLL Investor Holders’ rights to designate such individual to serve as a Specified Steiner Director.

(d) If an individual designated by the Majority SLL Investor Holders is not appointed, nominated or elected pursuant to Section 1(a) through (c) or this Section 1(d) because of such individual’s death, disability, disqualification or withdrawal as a designee or nominee or for any other reason (other than as a result of the Majority SLL Investor

Holders ceasing to be entitled to designate such individual pursuant to the other applicable provisions of Section 1), then the Majority SLL Investor Holders shall be entitled to designate a replacement to fill such director position by giving written notice to the Company, and the Company will, within ten (10) days of such designation, take all necessary and desirable actions so that such director position is filled with such person designated in writing pursuant to this Section 1(d) within such ten (10) day period. Notwithstanding anything to the contrary in this Agreement, the Investment Agreement or the Governing Documents of the Company, neither the Company Board nor any other Person (other than the Majority SLL Investor Holders pursuant to this Section 1(d)) may appoint, elect or designate any Person to fill any such director position described in the preceding sentence.

(e) As promptly as reasonably practicable following the request of any Steiner Director, the Company shall enter into an indemnification agreement with such Steiner Director, in the form entered into with the other members of the Company Board or, if not entered into by other members of the Company Board, a customary form. The Company shall pay the reasonable, documented and out-of-pocket expenses incurred by each Steiner Director related to his or her service to the Company, including attending meetings of the Company Board or any committee or sub-committee thereof or events attended on behalf of the Company or any of its Subsidiaries at the Company’s request.

(f) From and after the Closing and for so long as the SLL Investor Holders, in the aggregate, beneficially own at least 15.00% of the issued and outstanding Company Common Shares, the Company will, promptly upon (and in any event within five (5) Business Days (or within ten Business Days if any change requested by the Majority SLL Investor Holders would require any change to the composition of such committee other than the replacement of one Steiner Director with another Steiner Director) of) the written request of the Majority SLL Investor Holders, take all necessary and desirable actions within its control, so that the composition of each committee of the Company Board (other than any special committee with responsibility for a matter with respect to which any Steiner Person would have a conflict of interest or would not be disinterested) is comprised of a number of Steiner Directors in proportion to the number of Steiner Directors then serving on the Company Board as compared to the aggregate number of directors then serving on the Company Board (rounded up to the nearest whole number of directors, unless such rounding would result in a majority of any committee being comprised of Steiner Directors), with the Steiner Directors serving on each such committee at any time being determined in the sole discretion of the Majority SLL Investor Holders as provided in any such written request, unless the committee membership of such Steiner Director(s) would (together with any combination of non-Steiner Directors) violate the Listing Rules, the rules or regulations of the U.S. Securities and Exchange Commission, or applicable law based on a good faith determination of the Company Board (after consultation with applicable outside legal counsel). Without limiting the rights of the Majority SLL Investor Holders pursuant to the immediately preceding sentence, from and after the Closing and for so long as the SLL Investor Holders, in the aggregate, beneficially own at least 15.00% of the issued and outstanding Company Common Shares, if a committee of the Company Board (other than any special committee with responsibility for a matter with respect to which any Steiner Person would have a conflict of interest or would not be disinterested)

The Company or the committee of the Board on which such Steiner Director is a Steiner Committee Observer shall simultaneously provide (or cause to be provided) to such Steiner Committee Observer copies of all notices, consents, minutes and other materials that are provided to the members of such committee of the Company Board. A Steiner Committee Observer may be removed and/or, subject to the ownership thresholds required to appoint a Steiner Committee Observer, replaced at any time by the Majority SLL Investor Holders upon written notice to the Company Board of the same, and if after the appointment of a Steiner Committee Observer, a Steiner Director becomes a member of a committee of the Board, then such Steiner Committee Member shall no longer be entitled to serve as a Steiner Committee Observer for so long as a Steiner Director is a member of such committee.

(g) For so long as any Steiner Director serves as a director of the Company, the Company shall not amend, alter or repeal any right to indemnification or exculpation covering or benefiting any Steiner Director as and to the extent consistent with applicable law, including but not limited to under the Governing Documents of the Company (whether such right is contained in the Governing Documents of the Company or another document) (except to the extent such amendment or alteration permits the Company to provide broader indemnification or exculpation rights on a retroactive basis than permitted prior thereto).

(h) Subject to compliance with the Listing Rules, each Steiner Director may, but is not required to, qualify as “independent” pursuant to the Listing Rules.

(i) Each Steiner Director who is an employee of L Catterton or any affiliated “L Catterton” entity (it being understood that portfolio companies of investment vehicles advised by L Catterton (or advised by affiliates of L Catterton) shall not be considered an “affiliated “L Catterton” entity”) will have the option, in his or her sole discretion, to receive cash in lieu of any Equity Securities as compensation for his or her service as a director, determined based on the arithmetic average of the volume-weighted average price per Company Common Share for the period of the five (5) consecutive trading days ending on the trading day immediately preceding the date of such payment.

Except as otherwise specified herein, references to a Person are also to its successors and permitted assignees of rights and obligations under this Agreement. Masculine gender shall also include the feminine and neutral genders, and vice versa. The word “day” means calendar day unless Business Day is expressly specified. If any action under this Agreement is required to be done or taken on a day that is not a Business Day, then such action shall be required to be done or taken not on such day but on the first succeeding Business Day thereafter.

Section 6. Essential Consideration. The parties hereto acknowledge and agree that the rights and obligations of the parties hereunder, including under Section 1 through 4, are given in consideration for the rights and obligations undertaken under the Investment Agreement, and without limiting the generality of the foregoing, constitute essential and integral consideration to the parties hereto for their execution or authorization of the Investment Agreement.

Section 7. Assignment; Benefit of Parties; Transfer. No party hereto may assign this Agreement or any of its rights or obligations hereunder and any assignment hereof will be null and void, except that, at or following the date that any Steiner Person that is not already party to or bound by this Agreement becomes a beneficial owner any Company Common Shares, such Steiner Person may become a party to this Agreement as an SLL Investor Holder Party by executing a joinder agreement, in substantially the form attached hereto as Exhibit A, and the Steiner Representative as of any determination may assign its rights under Section 22 to any other SLL Investor Holder as provided in Section 22. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors, legal representatives and assignees for the uses and purposes set forth and referred to herein and, for the avoidance of doubt, any references to the SLL Investor Holders shall, as the context requires, refer to any permitted assignees of the SLL Investor Holders’ rights and/or obligations hereunder.

Section 8. Remedies. Except as otherwise expressly provided herein, any and all remedies provided herein will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party hereto, and the exercise by a party hereto of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform their respective obligations under the provisions of this Agreement in accordance with their specific terms or otherwise breach such provisions. It is accordingly agreed that the parties hereto shall be entitled to seek an injunction or injunctions, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case without posting a bond or undertaking and without proof of damages and this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity.

Section 9. Notices. All notices, requests, claims, demands and other communications hereunder shall be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery in person, by facsimile (having obtained electronic delivery confirmation thereof), e-mail (having obtained electronic delivery confirmation thereof), or by registered or certified mail (postage prepaid, return receipt requested) to the other parties hereto as follows:

Section 11. No Strict Construction. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any party hereto.

Section 12. No Third-Party Beneficiaries. Nothing in this Agreement, express or implied, is intended or shall be construed to confer upon, or give to, any person or entity other than the parties hereto and their respective successors and assigns any remedy or claim under or by reason of this Agreement or any terms, covenants or conditions hereof, and all of the terms, covenants, conditions, promises and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their respective successors and assigns. Notwithstanding anything to the contrary in this Agreement, (a) each Steiner Director shall be an express third-party beneficiary of the provisions set forth in Section 1(e) and Section 4 and (b) each SLL Investor Holder who is not an SLL Investor Holder Party shall be an express third-party beneficiary of the provisions set forth in Section 1, Section 2 and Section 3.

Section 13. Further Assurances. Each of the parties hereto hereby agrees that it will, upon request of the Company (in the case of an SLL Investor Holder) and upon request of the Steiner Representative (in the case of the Company or HYAC) and without any consideration, hereafter execute and deliver any further documents, agreements, instruments of assignment, transfer or conveyance and take such further actions as may be necessary or desirable to effectuate the purposes hereof.

Section 14. Expenses. Except as otherwise expressly set forth herein or in the Investment Agreement, each of the parties hereto hereby agrees that each party hereto shall bear any fees and expenses incurred by or on behalf of, or paid or payable by, such party as a result of or in connection with this Agreement and the transactions contemplated herein.

Section 15. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile, e-mail, or scanned pages shall be effective as delivery of a manually executed counterpart to this Agreement.

Section 16. Governing Law. This Agreement shall be governed by and construed in accordance with the internal Laws of the State of Delaware applicable to agreements made and to be performed entirely within such state, without regard to the conflicts of law principles of such state or any other jurisdiction.

Section 17. Jurisdiction; Venue; Waiver of Jury Trial.

(a) Each of the parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of the Chancery Court of the State of Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction, the Delaware Superior Court or, if the Delaware Superior Court declines to accept jurisdiction, any state or federal court within the County of New York in the State of New York), for the purposes of any Action or other proceeding arising out of this Agreement and the rights and obligations arising hereunder and thereunder, and irrevocably and unconditionally waives any objection to the

15

laying of venue of any such Action or proceeding in any such court, and further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such Action or proceeding has been brought in an inconvenient forum. Each party hereto agrees that service of any process, summons, notice or document by registered mail to such party’s respective address set forth in Section 9 shall be effective service of process for any such Action or proceeding.

(b) EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, CLAIM OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED THERETO. EACH PARTY HERETO (I) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, CLAIM OR OTHER PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 17(B).

Section 18. Complete Agreement; Inconsistent Agreements. This Agreement, together with the Investment Agreement and the Governing Documents of the Company, represent the complete agreement between the parties hereto as to all matters covered hereby, and supersede any prior agreements or understandings between the parties. For the avoidance of doubt, the Prior Agreement is superseded by this Agreement and, upon the execution and delivery hereof, the Prior Agreement shall automatically, without any further action of any party hereto or any other Person, terminate and be of no further force and effect. In the event of any conflict between the terms of this Agreement, on the one hand, and the Investment Agreement and/or the Governing Documents of the Company, on the other hand, the terms of this Agreement shall govern and control.

Section 19. Severability. Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 20. Amendment and Waiver. Except as otherwise provided herein, (a) no waiver of any provision of this Agreement shall be effective against any party hereto unless such waiver is approved in writing by such party and (b) no modification or amendment of any provision of this Agreement shall be effective against any party hereto unless such modification or

16

amendment is approved in writing by the Company and the Steiner Representative. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

Section 21. Termination. This Agreement shall terminate, and be of no further force and effect, upon the earliest to occur of: (a) the consummation of a Company Sale; (b) mutual written consent of the Company and the Steiner Representative; and (c) the SLL Investor Holders, in the aggregate, beneficially own less than 5% of the issued and outstanding Company Common Shares; provided that the last sentence of Section 1(e), Section 1(g), Section 1(i), Section 4, and Sections 5 through 22 (to the extent related to the foregoing) shall not terminate upon the occurrence of the event described in clause (c) and shall continue to be in full force and effect (notwithstanding clause (c) hereof) until the time at which a Steiner Director no longer serves as a director of the Company.

Section 22. Ability to Act on Behalf of the SLL Investor Holders.

(a) The parties hereto acknowledge and agree that Steiner Representative is hereby appointed, authorized and empowered to act as the representative of the SLL Investor Holders and as the exclusive agent, proxy and attorney-in-fact for the SLL Investor Holders for all purposes of this Agreement (including the full power and authority on behalf of the SLL Investor Holders, as well as the Majority SLL Investor Holders, as applicable, (i) to execute and deliver any consents and other documents contemplated by this Agreement and any and all supplements, amendments, waivers or modification thereto, and otherwise to consummate the transactions contemplated herein and therein, (ii) to execute and deliver on behalf of the SLL Investor Holders any amendment or waiver hereto or to any other agreement contemplated hereunder, (iii) to dispute, compromise, settle and pay any claims made in connection with this Agreement and (iv) to do each and every act and exercise any and all rights which the SLL Investor Holders or the Majority SLL Investor Holders are permitted or required to do or exercise under this Agreement).

(b) Steiner Leisure shall serve as the initial Steiner Representative until it assigns its rights and obligations hereunder as the Steiner Representative to another SLL Investor Holder Party. All power, authority, rights, privileges and obligations conferred in this Agreement to a Steiner Representative shall apply to any successor Steiner Representative. The Steiner Representative shall promptly notify the Company in writing upon any change in the identity of the Steiner representative. The Company shall be entitled to treat Steiner Leisure (or any successor Steiner Representative of which the Company has received notice in accordance with the preceding sentence) as the Steiner Representative until the Company has received the notice described in the preceding sentence.

(c) The appointment of the Steiner Representative by each Steiner Investor Holder is coupled with an interest and may not be revoked in whole or in part (including upon the death or incapacity of the Steiner Representative). Such appointment shall be binding upon the heirs, executors, administrators, estates, personal representatives, officers, managers, successors and assigns of each Steiner Investor Holder. All decisions

17

of the Steiner Representative shall be final and binding on all of the Steiner Investor Holders, and no Steiner Investor Holder shall have the right to object, dissent, protest or otherwise contest the same. The Company shall be entitled to rely upon, without independent investigation, any act, notice, instruction or communication from the Steiner Representative and any document executed by the Steiner Representative on behalf of the Steiner Investor Holders or Majority SLL Investor Holders, and the Company shall be fully protected in connection with any action or inaction taken or omitted to be taken in reliance thereon.
