LETTER OF TRANSMITTAL

To Exchange Securities of Xynomic Pharmaceuticals, Inc. Pursuant to the Merger of Bison Capital Merger Sub Inc. and Xynomic Pharmaceuticals, Inc.

This letter of transmittal (this “Letter of Transmittal”) is being furnished in connection with the merger of Bison Capital Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Bison Capital Acquisition Corp., a British Virgin Islands company which, prior to the consummation of the transactions contemplated by the Merger Agreement (as defined below), will domesticate as a Delaware corporation and, immediately thereafter will be known as “Xynomic Pharmaceuticals Holdings, Inc.” (the “Parent”), with and into Xynomic Pharmaceuticals, Inc., a Delaware corporation (the “Company”), pursuant to the Agreement and Plan of Merger, dated as of [●], 2018 (as amended from time to time in accordance with the terms thereof, the “Merger Agreement”), by and among (i) the Company, (ii) Parent, (iii) Bison Capital Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of Parent (the “Merger Sub”), and (iv) Yinglin Xxxx Xx, an individual residing in Shanghai, China, in his capacity as the Stockholder Representative (the “Stockholder Representative”). Pursuant to the Merger Agreement, and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company, with the Company surviving the Merger as a wholly-owned subsidiary of Parent (the “Merger”). At the effective time of the Merger (the “Effective Time”), each issued and outstanding share of capital stock of the Company (other than shares in respect of which appraisal rights have been properly exercised and perfected to the extent available under Section 262 of the General Corporation Law of the State of Delaware and shares held by the Company or Parent) (the “Company Stock”) will be cancelled and cease to exist in exchange for the right to receive the Merger Consideration Shares and options to acquire common stock of the Company (each, a “Company Option”) (whether vested or unvested) shall be assumed by Parent and automatically converted into an option to acquire common stock of Parent, with its price and number of shares equitably adjusted based on the conversion of the Company Stock into the Merger Consideration Shares. Any capitalized term used but not defined in this Letter of Transmittal will have the meaning ascribed to such term in the Merger Agreement.

The undersigned holder (“Holder”) of Company Stock understands that this Letter of Transmittal is being provided to both the Company and Parent in connection with, and as a condition to the consummation of the Merger, and that the Company and Parent are consummating the Merger and the other transactions contemplated by the Merger Agreement in reliance upon the representations, warranties, covenants and agreements of the Holder set forth in this Letter of Transmittal.

IN ADDITION, HOLDER HAS READ, UNDERSTANDS AND AGREES TO ALL OF THE TERMS AND CONDITIONS SET FORTH IN THE MERGER AGREEMENT, THE TRANSACTION DOCUMENTS TO WHICH THE HOLDER IS BOUND, THE MATERIALS ACCOMPANYING THIS LETTER OF TRANSMITTAL AND THE ACCOMPANYING INSTRUCTIONS BEFORE COMPLETING ANY OF THE INFORMATION BELOW.

Please read carefully this entire Letter of Transmittal and the accompanying instructions before completing any of the boxes below.

IMPORTANT: Holders of shares of capital stock of the Company will be entitled to appraisal rights in connection with the Merger. If Holder did not vote in favor of the Merger and wishes to exercise appraisal rights under Delaware law in connection with the Merger, Holder should carefully review, in consultation with legal counsel, Holder’s rights to appraisal as provided by Delaware law before certificates formerly representing Company Stock are surrendered for exchange.

1. Representations and Warranties of Holder. Holder hereby represents, warrants and covenants to the Company and Parent as follows as of the date of this Letter of Transmittal and as of the Effective Time:

(a) Ownership of Securities. All of the Company Stock owned by the Holder, including without limitation the number, type, class and series thereof, are set forth and accurately described in Schedule 1 below (the “Holder Company Stock”). Holder has beneficial ownership of, is the lawful owner of, and has good and valid title to, the Holder Company Stock, free and clear of any and all pledges, mortgages, encumbrances, charges, proxies, voting agreements, liens, adverse claims, options, security interests and demands of any nature or kind whatsoever (other than those imposed by applicable securities laws or the Company’s organizational documents, as in effect on the date hereof). There are no claims for finder’s fees or brokerage commission or other like payments in connection with the Merger Agreement or the transactions contemplated thereby payable by Holder pursuant to arrangements made by such Holder. Except for the Holder Company Stock set forth on Schedule 1 and any Company Options, Holder is not a beneficial owner or record holder of any: (i) equity securities of the Company, (ii) securities of the Company having the right to vote on any matters on which the holders of equity securities of the Company may vote, or (iii) options, warrants or other rights to acquire from the Company any equity securities or securities convertible into or exchangeable for equity securities of the Company.

(b) Binding Agreement. Holder (i) if a natural person, is of legal age to execute this Letter of Transmittal and each of the Exhibits hereto, including the Lock-Up Agreement and the Amended and Restated Registration Rights Agreement, and any other document required by this Letter of Transmittal (collectively with the Letter of Transmittal, the “Transmittal Documents”), and is legally competent to do so and (ii) if not a natural person, is (A) a corporation or other entity duly organized and validly existing under the laws of the jurisdiction of its organization and (B) has all necessary power and authority to execute and deliver the Transmittal Documents, to perform its obligations hereunder and thereunder and to consummate the transactions contemplated hereby and thereby. If Holder is not a natural person, the execution and delivery of the Transmittal Documents, the performance of its obligations hereunder and thereunder and the consummation of the transactions contemplated hereby and thereby by Holder has been duly authorized by all necessary corporate or similar action on the part of Holder. This Letter of Transmittal and each other Transmittal Document, assuming due authorization, execution and delivery hereof by the other parties hereto and thereto, constitutes a legal, valid and binding obligation of Holder, enforceable against Holder in accordance with its terms (except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general applicability relating to or affecting creditor’s rights, and to general equitable principles).

(c) No Conflicts. No filing with, or notification to, any governmental authority, and no consent, approval, authorization or permit of any other person or entity is necessary for the execution of this Letter of Transmittal or any other Transmittal Document by Holder, the performance of its obligations hereunder or thereunder or the consummation by it of the transactions contemplated hereby or thereby. None of the execution and delivery of this Letter of Transmittal or any other Transmittal Document by Holder, the performance of its obligations hereunder or thereunder or the consummation by it of the transactions contemplated hereby or thereby will (i) conflict with or result in any breach of the organizational documents of Holder, if applicable, (ii) result in, or give rise to, a violation or breach of or a default under any of the terms of any contract or obligation to which Holder is a party or by which Holder or any of the Holder Company Stock or its other assets may be bound, or (iii) violate any applicable law or order, except for any of the foregoing in clauses (i) through (iii) as would not reasonably be expected to impair in any material respect Holder’s ability to perform its obligations under this Letter of Transmittal or the other Transmittal Documents. Holder has not entered into any agreement or knowingly taken any action (nor will enter into any agreement or knowingly take any action) that would make any representation or warranty of Holder contained in this Letter of Transmittal untrue or incorrect in any material respect or have the effect of preventing Holder from performing any of its material obligations under this Letter of Transmittal or any Transmittal Document.

(d) Investment Representations. Holder: (i) is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”); (ii) is acquiring its portion of the Merger Consideration Shares for itself for investment purposes only, and not with a view towards any resale or distribution of such Merger Consideration Shares; (iii) has been advised and understands that the Merger Consideration Shares (A) are being issued in reliance upon one or more exemptions from the registration requirements of the Securities Act and any applicable state securities laws, (B) have not been and shall not be registered under the Securities Act or any applicable state securities laws and, therefore, must be held indefinitely and cannot be resold unless such Merger Consideration Shares are registered under the Securities Act and all applicable state securities laws, unless exemptions from registration are available and (C) will be subject to additional restrictions on transfer pursuant to the Lock-Up Agreement; (iv) is aware that an investment in Parent is a speculative investment and is subject to the risk of complete loss; and (v) acknowledges that Parent is under no obligation hereunder to register the Merger Consideration Shares under the Securities Act (except as may be set forth in the Amended and Restated Registration Rights Agreement). Holder does not have any contract with any person or entity to sell, transfer, or grant participations to such person or entity, or to any third person or entity, with respect to the Merger Consideration Shares. By reason of Holder’s business or financial experience, or by reason of the business or financial experience of Holder’s “purchaser representatives” (as that term is defined in Rule 501(h) under the Securities Act), Holder is capable of evaluating the risks and merits of an investment in Parent and of protecting its interests in connection with this investment. Holder has carefully read and understands all materials provided by or on behalf of Parent or its affiliates or the managers, directors, officers, employees, agents or advisors of Parent or its affiliates (collectively, “Parent’s Representatives”) to Holder or its affiliates or the managers, directors, officers, employees, agents or advisors of Holder or its affiliates (collectively, the “Holder’s Representatives”) pertaining to an investment in Parent and has consulted, as Holder has deemed advisable, with its own attorneys, accountants or investment advisors with respect to the investment contemplated hereby and its suitability for Holder. Holder acknowledges that the Merger Consideration Shares are subject to dilution for events not under the control of Holder. Holder has completed its independent inquiry and has relied fully upon the advice of its own legal counsel, accountant, financial and other Holder’s Representatives in determining the legal, tax, financial and other consequences of the Merger Agreement and the Transmittal Documents and the transactions contemplated hereby and thereby and the suitability of the foregoing for Holder and its particular circumstances, and has not relied upon any representations or advice by Parent or Parent’s Representatives. Holder acknowledges and agrees that no representations or warranties have been made by Parent or any Parent Representative to Holder, and that Holder has not been guaranteed or represented to by any person or entity, (i) any specific amount or the event of the distribution of any cash, property or other interest in Parent or (ii) the profitability or value of the Merger Consideration Shares in any manner whatsoever. Holder: (A) has been represented by independent counsel (or has had the opportunity to consult with independent counsel and has declined to do so); (B) has had the full right and opportunity to consult with Holder’s attorneys and other advisors and has availed itself of this right and opportunity; (C) has carefully read and fully understands the Merger Agreement and this Letter of Transmittal and the other Transmittal Documents in their entirety and has had them fully explained to it by such counsel; (D) is fully aware of the contents hereof and the meaning, intent and legal effect thereof; and (E) is competent to execute this Letter of Transmittal and the other Transmittal Documents and has executed this Letter of Transmittal and the other Transmittal Documents free from coercion, duress or undue influence.

2. Escrow and Indemnification. Holder acknowledges, covenants and agrees that (a) pursuant to Section 1.10 of the Merger Agreement, 3% of the Closing Parent Share Consideration and 3% of the Earnout Parent Share Consideration (if payable) (collectively, the “Escrow Shares”) will be held in escrow for up to eighteen (18) months after the Closing Date (the “Indemnity Escrow Period”) (subject to amounts retained in escrow thereafter for then pending claims) and shall serve as security for, and a source of payment of, (i) the indemnification rights of Parent, its affiliates and their respective officers, directors, managers, employees, successors and permitted assigns (collectively, the “Indemnified Parties”) pursuant to Article X of the Merger Agreement and (ii) any post-closing merger consideration adjustment in favor of Parent pursuant to Section 1.05 of the Merger Agreement. Consequently, Holder’s Pro Rata Share (as defined in the Merger Agreement) of the Escrow Shares will be held in escrow in accordance with the Merger Agreement and the Escrow Agreement to be entered into in connection with the Merger Agreement. Holder will be required to provide several indemnification to the Indemnified Parties for claims made during the Indemnity Escrow Period to the extent of the Escrow Shares then remaining in the escrow account.

3. Disposition of Company Stock. Pursuant to the Merger Agreement, Holder hereby surrenders, cancels and terminates Holder’s shares of Company Stock in exchange for the Merger Consideration Shares payable in respect of such shares of Company Stock (net of any Escrow Shares) pursuant to the Merger Agreement. Holder hereby authorizes and instructs the Exchange Agent to issue to Holder the portion of Merger Consideration Shares (less the Escrow Shares) due to Holder as a result of the Merger.

4. Appointment of Stockholder Representative to Act on Holder’s Behalf. By the execution and delivery of this Letter of Transmittal, Holder on behalf of itself and its successors and assigns, hereby agrees to the provisions of Section 12.01 of the Merger Agreement and irrevocably constitutes and appoints Yinglin Xxxx Xx in his capacity as the Stockholder Representative as set forth in the Merger Agreement, as the true and lawful agent and attorney-in-fact of Holder with full powers of substitution to act in the name, place and stead thereof with respect to the performance on behalf of Holder to the extent set forth in Section 12.01 of the Merger Agreement.

5. Release of Claims. In consideration of the receipt of its Merger Consideration Shares, Holder, intending to be legally bound, effective as of the Effective Time hereby releases and discharges the Company and its affiliates and their respective directors, officers, employees, agents, representatives, successors and assigns (collectively, “Releasees”) fully, finally and forever, from all and any manner of claims, actions, rights, causes of action, suits, obligations, liabilities, debts, due sums of money, agreements, promises, damages, judgments, executions, accounts, expenses, costs, attorneys’ fees and demands whatsoever, whether in law, contract or equity, whether known or unknown, matured or unmatured, foreseen or unforeseen (collectively, “Claims”), arising out of events existing or occurring contemporaneously with or prior to the Effective Time, in each case, in Holder’s capacity as a stockholder or option holder of the Company (or its predecessors) or otherwise relating to Holder’s acquisition, ownership, control or sale of Company Stock; provided, that nothing contained herein shall operate to release (i) any liabilities of a Releasee based upon, arising out of or relating to, without duplication, this Letter of Transmittal or any of the other Transmittal Documents, the Merger Agreement, or any of the Transaction Documents, (ii) the Company for claims for Fraud made by Parent against the Company or any of its subsidiaries under the Merger Agreement for which Holder has any responsibility beyond the Escrow Shares, (iii) any claim Holder may have, in his or her capacity as an employee, director or officer of the Company or any of its subsidiaries, for indemnification by the Company or any of its subsidiaries, whether pursuant to an indemnification agreement, under the Company’s organizational documents as in effect immediately prior to the Closing or pursuant to applicable law, and any related rights as a named insured under any Company insurance policy relating thereto or (iv) any claim Holder may have for vested benefits and unpaid wages that are owed to Holder in his or her capacity as an employee, director, officer or consultant of the Company or any of its subsidiaries. Holder hereby irrevocably covenants to refrain from, directly or indirectly, asserting, commencing or instituting any cause of action, suit or claim of any kind against any Releasee based upon any matter intended or purported to be released hereby. This release may not be altered except in a writing signed by the person or entity against whose interest such change shall operate.

6. Post-Closing Confidentiality. Holder hereby agrees for a period of two (2) years from and after the date hereof to, and to direct Holder’s Representatives to: (i) treat and hold in strict confidence any Company Confidential Information (as defined below), and not use for any purpose (except in connection with the consummation of the transactions contemplated by this Letter of Transmittal, the Merger Agreement or the Transaction Documents, performing its obligations hereunder or thereunder or enforcing its rights hereunder or thereunder), nor directly or indirectly disclose, distribute, publish, disseminate or otherwise make available to any third party any of the Company Confidential Information without the Company’s and Parent’s prior written consent. As used in this Letter of Transmittal, “Company Confidential Information” means all material and information relating to the business, affairs and assets of the Company or its subsidiaries, including material and information that concerns or relates to the Company or its subsidiaries’ bidding and proposal, technical, computer hardware or software, administrative, management, operational, data processing, financial, marketing, sales, human resources, business development, planning and/or other business activities, and information regarding genetic or other biological materials, gene sequences, cell lines, viruses, plasmids, vectors, compounds, protocols, assays and clinical trials, regardless of whether such material and information is maintained in physical, electronic, or other form, that is: (A) gathered, compiled, generated, produced or maintained by the Company or its subsidiaries, or provided to the Company or its subsidiaries by their respective suppliers, service providers or customers; and (B) intended and maintained by the Company or its subsidiaries or their respective representatives, suppliers, service providers or customers to be kept in confidence. The obligations set forth in this Section 6 will not apply to any Company Confidential Information that: (i) is known or available through other lawful sources not known by Holder to be bound by a confidentiality agreement with, or other confidentiality obligation to, the Company or its subsidiaries; (ii) is or becomes publicly known through no violation of this Letter of Transmittal or other non-disclosure obligation of Holder or any of Holder’s Representatives; (iii) is already in the possession of Holder at the time of disclosure, provided that such information is not known to Holder to be subject to another confidentiality agreement or other confidentiality obligation; (iv) is independently developed by or for Holder or any of Holder’s Representatives without derivation from, reference to or reliance upon, or using in any manner, Company Confidential Information and without violating any of the confidentiality obligations under this Letter of Transmittal or (v) is required to be disclosed by applicable law, regulation, stock exchange rule or other market or reporting system, pursuant to an order of any administrative body or court of competent jurisdiction, or by other legal, judicial, regulatory or administrative process (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process) (provided that, with respect to this clause (v), (A) the Company is given reasonable prior written notice, (B) Holder cooperates (and directs Holder’s Representatives to cooperate), at the Company’s sole cost and expense, with any reasonable request of the Company to seek to prevent or narrow such disclosure and (C) if after compliance with clauses (A) and (B) such disclosure is still required, Holder and Holder’s Representatives will only disclose such portion of the Company Confidential Information that is expressly required by such order, as it may be subsequently narrowed). Notwithstanding the foregoing, in the event that Holder is already subject to confidentiality obligations to the Company which are in effect as of the Closing Date which provide that such confidentiality obligations are the sole confidentiality provisions with respect to the Company applicable to Holder, then those confidentiality obligations will apply to Holder in lieu of the provisions of this Section 6. Nothing in the Section 6 shall limit the right of the Holder to provide any information required by law to any tax authority and no notice of such disclosure shall be required to be given to the Company.
