Section 2.1 Transfer and Encumbrance of Shares. From the date of this Agreement until the earliest of (i) Company Stockholder Approval being obtained, (ii) the termination of the Merger Agreement pursuant to and in compliance with the terms thereof, (iii) if at any time prior to receipt of Company Stockholder Approval, a Company Change of Recommendation in accordance with Section 6.3(e) of the Merger Agreement occurs, (iv) as to a Holder, the date of any modification, waiver or amendment to the Merger Agreement effected without such Holder’s consent that decreases the amount or changes the form of Merger Consideration payable to all of the holders of shares of Company Common Stock and Heat OpCo Membership Interests pursuant to the terms of the Merger Agreement as in effect on the date of this Agreement, (v) any breach of the representations and warranties of Parent set forth in Section 5.2(c), or (vi) the termination of this Agreement by the written consent of the parties hereto (such earliest date, the “Termination Date”), each Holder shall not, with respect to any Shares Beneficially Owned by such Holder as of the date of this Agreement or to any class or series of Heat OpCo Membership Interests

Notwithstanding the foregoing, this Section 2.1 shall not prohibit (i) direct or indirect Transfers of capital stock or other interests in any Holder or (ii) a Transfer of any Shares by any Holder to any of its Affiliates; provided, that a Transfer described in this clause (ii) shall be permitted only if, as a precondition to such Transfer, (A) the transferee agrees in a writing, reasonably satisfactory in form and substance to Parent, to be bound by all of the terms of this Agreement and (B) the Holder Transfers all, but not less than all, of its Shares to only one (1) Person.

Section 2.2 Additional Purchases; Adjustments. Each Holder agrees that any shares of Company Common Stock and any other shares of capital stock or other equity of the Company that such Holder purchases or otherwise acquires or with respect to which such Holder otherwise acquires voting power after the execution of this Agreement and prior to the Termination Date shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted the Shares as of the date of this Agreement, and each Holder shall promptly notify the Company of the existence of any such after-acquired Shares. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of shares or the like of the capital stock of the Company affecting the Shares, the terms of this Agreement shall apply to the resulting securities.

Section 2.3 Unpermitted Transfers; Involuntary Transfers. Any Transfer or attempted Transfer of any Shares or Heat OpCo Membership Interests in violation of this Article II shall, to the fullest extent permitted by applicable Law, be null and void ab initio. In furtherance of the foregoing, each Holder hereby authorizes and instructs the Company to instruct its transfer agent to enter a stop transfer order with respect to all of the Shares and Heat OpCo Membership Interests and to instruct the Company in its capacity as sole managing member of Heat OpCo not to recognize any Transfer of Heat OpCo Membership Interests in violation of Article II on the books and records of Heat OpCo; provided, that such stop transfer order or other prohibition shall be removed with respect to any Transfer permitted under this Agreement. If any involuntary Transfer of any of a Holder’s Shares or a Holder’s Heat OpCo Membership Interests shall occur, the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Shares or Heat OpCo Membership Interests subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement.

ARTICLE III

AGREEMENT TO CONSENT AND VOTE

Section 3.1 Agreement to Vote. Prior to the Termination Date, each Holder irrevocably and unconditionally agrees that it shall, at any meeting of the stockholders of the Company (whether annual or special and whether or not an adjourned or postponed meeting), however called, appear at such meeting or otherwise cause the Shares to be counted as present at such meeting for purpose of establishing a quorum and vote, or cause to be voted at such meeting, all Shares it owns:

(a) in favor of the approval of the Transactions, adoption of the Merger Agreement and approval of any other matters necessary for consummation of the Transactions, including the Company Mergers (collectively, the “Transaction Matters”); and

(b) against (i) any agreement, transaction or proposal that relates to a Company Competing Proposal or any other transaction, proposal, agreement or action made in opposition to adoption of the Merger Agreement or in competition or inconsistent with the Transactions or matters contemplated by the Merger Agreement; (ii) any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company or any of its Subsidiaries contained in the Merger Agreement or of such Holder contained in this Agreement; (iii) any action or agreement that would reasonably be expected to result in (x) any condition to the consummation of the Transactions set forth in Article VII of the Merger Agreement not being fulfilled or (y) any change to the voting rights of any class of shares of capital stock of the Company (including any amendments to the Company’s Organizational Documents); and (iv) any other action that would reasonably be expected to impede, interfere with, delay, discourage, postpone or adversely affect any of the Transactions, including the Mergers, or this Agreement in any material respect. Any attempt by a Holder to vote, consent or express dissent with respect to (or otherwise to utilize the voting power of), the Shares in contravention of this Section 3.1 shall be null and void ab initio. If any Holder is the Beneficial Owner, but not the holder of record, of any Shares, such Xxxxxx agrees to take all actions necessary to cause the holder of record and any nominees to vote (or exercise a consent with respect to) all of such Shares in accordance with this Section 3.1.

Notwithstanding anything herein to the contrary in this Agreement, this Section 3.1 shall not require any Holder to be present (in person or by proxy) or vote (or cause to be voted), any of the applicable Shares to amend, modify or waive any provision of the Merger Agreement in a manner that reduces the amount, changes the form of the Merger Consideration payable or extends the Outside Date in any material respect. Notwithstanding anything to the contrary in this Agreement, each Holder shall remain free to vote (or execute consents or proxies with respect to) the applicable Shares with respect to any matter other than as set forth in Section 3.1(a) and Section 3.1(b) in any manner such Holder deems appropriate, including in connection with the election of directors of the Company.

Section 3.2 Proxy. Each Holder hereby irrevocably appoints as its proxy and attorney-in-fact, Parent and any Person designated in writing by Parent, each of them individually, with full power of substitution and resubstitution, to vote the Shares as indicated in, and solely for the matters set forth in, Section 3.1(a) and Section 3.1(b) above. Each Holder intends this proxy to be irrevocable and unconditional during the term of this Agreement and coupled with an interest and will take such further action or execute such other instruments as may be reasonably necessary to effect the intent of this proxy, and hereby revokes any proxy previously granted by such Holder with respect to the Shares (and each Holder hereby represents that any such proxy is revocable). The proxy granted by any Holder (i) shall be automatically revoked upon the occurrence of the Termination Date and (ii) may be terminated at any time by Parent in its sole election by written notice provided to such Holder.

ARTICLE IV

ADDITIONAL AGREEMENTS

Section 4.1 Waiver of Appraisal Rights. To the fullest extent permitted by Law, the Holder hereby irrevocably and unconditionally waives, and agrees to refrain from exercising, any rights of appraisal (including under Section 262 of the DGCL), any dissenters’ rights and any similar rights relating to the Transactions that the Holder may directly or indirectly have by virtue of the ownership of any Shares.

Section 4.2 Tax Matters With Respect to Heat OpCo.

(a) Intended Tax Treatment. Bold expressly acknowledges and agrees to the “Intended Tax Treatment” described in the Merger Agreement, including that immediately prior to the OpCo Merger, Bold will be treated as having sold a partnership interest in Heat OpCo to Pacers OpCo to the extent of any cash to be paid in lieu of fractional Pacers OpCo Units in accordance with Section 3.5(h) of the Merger Agreement and any cash to be paid in satisfaction of a withholding Tax in accordance with Section 3.5(j)(i)(B) of the Merger Agreement in a manner consistent with Treasury Regulations § 1.708-1(c)(4), and Bold hereby expressly consents to such treatment as required by Treasury Regulations § 1.708-1(c)(4).

(b) Withholding Certificates. At or prior to the Closing, Bold will deliver a properly executed IRS Form W-9 with respect to itself to Parent and Pacers OpCo.

(c) Tax Returns. Parent shall prepare, or cause to be prepared, each Pre-Closing Flow-Through Tax Return required to be filed after the Closing with respect to Heat OpCo in a manner consistent with past practice, except to the extent otherwise required by applicable Law or this Agreement or the Merger Agreement. Not later than 10 days prior to the due date (including extensions) for filing any such Pre-Closing Flow-Through Tax Return, Parent shall deliver a draft of each such Pre-Closing Flow-Through Tax Return, together with any supporting documentation and workpapers reasonably requested by Bold that may be necessary to understand such Pre-Closing Flow-Through Tax Return, to Bold for its review and reasonable comment. Parent shall consider in good faith any reasonable comments timely received from Bold prior to filing.

(d) Tax Proceedings. After the Closing, Bold shall, at its sole cost and to the extent permitted by the applicable taxing authority, be entitled to participate in any audit, examination, contest, litigation or other Proceeding relating to Pre-Closing Flow-Through Taxes with respect to Heat OpCo, and none of Parent, the Surviving Company, the Surviving OpCo or any of their Affiliates shall settle or compromise any such Proceeding without the prior written consent of Bold (such consent not to be unreasonably withheld, conditioned or delayed) if such settlement or compromise would reasonably be expected to have a disproportionate (as compared to Parent) and material adverse effect on Bold.

(e) Cooperation. Parent shall (and shall cause its Subsidiaries to) and Bold shall reasonably cooperate as and to the extent reasonably requested by the other Party in connection with the filing of any Tax Returns described in Section 4.2(c) and any Proceeding described in Section 4.2(d).

Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Party requesting cooperation under this Section 4.2(e) shall reimburse the Party providing such cooperation for any reasonable out-of-pocket costs or expenses incurred by the providing Party.

(f) Distribution Tax Treatment. For U.S. federal (and applicable state and local) income Tax purposes, the parties hereto shall endeavor to treat any distribution to the unitholders or former unitholders of Heat OpCo pursuant to Section 6.23 of the Merger Agreement as a distribution under Section 731 of the Code by Heat OpCo prior to the OpCo Merger or by Pacers OpCo following the OpCo Merger, as applicable (such treatment, the “Distribution Tax Treatment”), and, to the extent permitted by applicable Law at a “more likely than not” (or higher) level of comfort, the parties hereto shall (and shall cause their Subsidiaries and Affiliates to) treat any such distribution in a manner consistent with the Distribution Tax Treatment for U.S. federal (and applicable state and local) income Tax purposes, and file their applicable Tax Returns consistent with the Distribution Tax Treatment. To the extent the Distribution Tax Treatment is not permitted by applicable Law at a “more likely than not” (or higher) level of comfort and the parties hereto determine they are required by applicable Law to treat any such distribution as consideration received in connection with the OpCo Merger, the parties hereto shall (and shall cause their Subsidiaries and Affiliates to) treat any such distribution as consideration in connection with a “sale within a merger” of Heat OpCo Units by the relevant holder thereof occurring immediately prior to the OpCo Merger in accordance with Treasury Regulations § 1.708-1(c)(4) to the extent the relevant holder consents to such treatment in accordance with such Treasury Regulations. In such a case, Bold hereby expressly consents to such treatment as required by Treasury Regulations § 1.708-1(c)(4).

Section 4.3 Further Assurances. Each Holder agrees that from and after the date of this Agreement and until the Termination Date, each Holder shall take no action that would reasonably be likely to adversely affect or delay the ability to obtain any necessary approvals of any Antitrust Authority or the Company Stockholder Approval, as applicable, or other Governmental Entity required for the Transactions or to perform its covenants and agreements under this Agreement.

Section 4.4 Fiduciary Duties. Each Holder is entering into this Agreement solely in its capacity as the record owner or Beneficial Owner of the Shares and nothing herein is intended to or shall limit or affect any actions taken by any of such Xxxxxx’s designees serving in his or her capacity as a director of the Company (or a Subsidiary of the Company). The taking of any actions (or failures to act) by such Xxxxxx’s designees serving as a director of the Company (in such capacity as a director) shall not be deemed to constitute a breach of this Agreement.

Section 6.13 Expenses. Each party hereto shall pay its own expenses incident to preparing for, entering into and carrying out this Agreement and the consummation of the transactions contemplated this Agreement, whether or not the Mergers shall be consummated.

Section 6.14 Non-Recourse. This Agreement may only be enforced against, and any claim or cause of action based upon, arising out of, or related to this Agreement or the transactions contemplated by this Agreement may only be brought against, the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party. Except to the extent a named party to this Agreement (and then only to the extent of the specific obligations undertaken by such named party in this Agreement and not otherwise),

no past, present or future director, manager, officer, employee, incorporator, member, partner, equityholder, Affiliate, agent, attorney, advisor, consultant or Representative or Affiliate of any of the foregoing shall have any liability (whether in Contract, tort, equity or otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities of any one or more party under this Agreement (whether for indemnification or otherwise) or of or for any claim based on, arising out of, or related to this Agreement or the transactions contemplated by this Agreement.

Section 6.15 Injunctive Relief. The parties hereto agree that irreparable damage, for which monetary damages would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached by the parties hereto. Prior to the termination of this Agreement pursuant to Section 6.3, it is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction, in each case in accordance with this Section 6.15, this being in addition to any other remedy to which they are entitled under the terms of this Agreement at Law or in equity. Each party hereto accordingly agrees (a) the non-breaching party will be entitled to injunctive and other equitable relief, without proof of actual damages; and (b) the alleged breaching party will not raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party under this Agreement and will not plead in defense thereto that there are adequate remedies at Law, all in accordance with the terms of this Section 6.15. Each party hereto further agrees that no other party hereto or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 6.15, and each party hereto irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Section 6.16 No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to the Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to Holders, and Parent shall not have any authority to manage, direct, restrict, regulate, govern or administer any of the policies or operations of the Company or exercise any power or authority to direct Holders in the voting or disposition of any Shares, except as otherwise expressly provided herein.

Section 6.17 Disclosure. Each Holder consents to and authorizes the publication and disclosure by the Company and Parent of such Xxxxxx’s identity and holding of Shares, and the terms of this Agreement (including, for avoidance of doubt, the disclosure of this Agreement), in any press release, the Joint Proxy and Solicitation Statement, and any other disclosure document required in connection with the Merger Agreement and the Transactions.

Accordingly, any rule of Law or any legal decision that would require interpretation of any ambiguities in this Agreement against any party hereto that drafted it is of no application and is hereby expressly waived.

(b) Notwithstanding anything in this Agreement to the contrary, each Holder’s representations, warranties and obligations hereunder are only with respect to itself and the Shares it owns, and such Holder is not responsible for any breach by any other Holder or with respect to such other Holder’s Shares.
