Exhibit 10.2

This Trading Authorization Agreement (“Agreement”) is made as of ____, by and between ConvexityShares LLC, a Delaware limited liability company (“Manager”), which is registered as a commodity pool operator (“CPO”) with the Commodity Futures Trading Commission (“CFTC”), and Teucrium Trading LLC, a Delaware limited liability company (“Trading Advisor”), which is registered as a commodity trading advisor (“CTA”) and commodity pool operator with the CFTC. Manager and Trading Advisor are each individually also referred to herein as a “Party” and collectively as the “Parties.”

WHEREAS, Manager provides certain advisory services to the ConvexityShares Trust, which is a Delaware statutory trust (“Trust”); and

WHEREAS, Manager desires to engage Trading Advisor, as a third party trading advisor, for the purpose of obtaining commodity trading advice and directing the trading of Commodity Interests (as defined herein) with respect to the Trust and designated series thereof (“Series”), as set forth on Exhibit A; and

WHEREAS, Trading Advisor hereby accepts such engagement pursuant to the terms set forth in this Agreement; and

WHEREAS, Manager has furnished the Trading Advisor with copies of each of the following documents: (a) the Trust’s Agreement and Declaration of Trust (such Agreement and Declaration of Trust, as in effect on the date of this Agreement and as amended from time to time, herein called the “Declaration of Trust”); (b) By-Laws of the Trust (if any), as in effect on the date of this Agreement and as amended from time to time); (c) Prospectus and Statement of Additional Information of the Fund (“Prospectus” and “SAI”, respectively); and (d) policies and procedures of the Trust and the Trust service agreements that govern the Trading Advisor’s management of the Allocated Portion under this Agreement.

NOW, THEREFORE, in consideration of the mutual premises set forth above, the Parties hereto do hereby agree as follows:

1. Appointment. (a) Manager hereby appoints Trading Advisor as attorney-in-fact with power to supervise and direct, on a fully discretionary basis and without first consulting Manager, the investment of futures contracts and other commodity interests (such futures contracts and other commodity interests, collectively, “Commodity Interests”) in one or more trading accounts (“Accounts”) established and maintained by Manager for the Trust and Series with a futures commissions merchant (“FCM”) selected by Manager.

(b) The power-of-attorney granted hereof is a continuing power and shall remain in full force and effect until revoked by Manager, in writing, but any such revocation shall not affect any transaction initiated prior to receipt of such notice of revocation. Manager agrees to use commercially reasonably efforts to provide Trading Advisor such additional information as Trading Advisor may reasonably request from time to time to assist it in managing the Account. It is the intent of this Agreement that only Trading Advisor shall have authority to trade the Account assets on behalf of Manager except as otherwise explicitly provided herein.

2. Investment Services. (a) The Trading Advisor shall manage the provision of investment services consistent with the investment guidelines and restrictions set forth on Exhibit B (attached hereto and made a part hereof) for each Series (“Guidelines”). Manager will allocate capital to each Account from assets of the Trust (“Account Allocation”) to enable Trading Advisor to trade an Account in accordance herewith. The Manager may in its discretion increase or decrease such Account Allocation from time to time by providing Trading Advisor with written instructions. In addition, the Guidelines may be revised from time to time by Manager with 3 business days prior written notice to Trading Advisor for any reason including, but not limited to, adding additional strategies, modifying the current strategy, adding investment restrictions and/or providing risk parameters.

(b) Consistent with the Guidelines, Trading Advisor may purchase, sell (including selling short), trade and otherwise acquire, hold, dispose of, and deal in Commodity Interests, on margin or otherwise, on United States or foreign exchanges, in the interbank market and otherwise and to make and take delivery of commodities in fulfillment of any Commodity Interests for an Account. In furtherance of the foregoing, the Trading Manager shall:

(i) subject to Exhibit B, make all decisions relating to the manner, method and timing of any and all investments;

(ii) buy, sell, exchange, transfer, and otherwise trade in property of all kinds as discussed on Exhibit B, in Client’s name;

(iii) make and execute, in the name and on behalf of Client, all such documents (including, without limitation, customer agreements and other documents in connection with the establishment and maintenance of accounts and investments) and to take all such other reasonable actions which Trading Advisor considers necessary or advisable to carry out its investment management duties hereunder;

(iv) submit reports, statement, or records relating to all transactions concerning the Account upon Manager's reasonable request;

(v) maintain and preserve the records relating to its activities hereunder required by applicable law to be maintained and preserved by the Trading Adviser;

(vi) assist Client’s auditors and others in the performance of all accounting and administrative services which may be required by Client;

3. Regulations. Any and all transactions effected by Trading Advisor for an Account shall be subject to the constitution, by-laws, rules, regulations, orders, and customs and usages of the exchange or market where executed (and of its FCM, if any), to the provisions of the United States Commodity Exchange Act, as amended (“CEA”), to the rules, regulations, and orders promulgated from time to time thereunder, to all applicable laws, rules, and regulations of the United States, the various states in the United States, and to policies adopted by Manager and communicated in writing to Trading Advisor. Trading Advisor shall not be liable to Manager as a result of any action taken by Trading Advisor that is necessary to comply with any such constitution, by-law, rule, regulation, order, custom, usage, act, or statute. Notwithstanding the foregoing, Trading Advisor agrees to notify Manager immediately to the extent Trading Advisor takes any action on behalf of any Account which is or may be considered adverse to such Account, the Trust or the Manager as a result of the foregoing so as to enable Manager to take any action in connection therewith.

4. Allocation of Expenses. Each Party to this Agreement shall bear the costs and expenses of performing its obligations hereunder. The parties acknowledge and agree that the Series shall assume the expense of:

(a) all margins, option premiums, brokerage and floor commissions and fees, and other transaction costs and expenses charged and incurred by the FCM in connection with the applicable Account;

(b) brokerage commissions for transactions and similar fees and charges for the acquisition, disposition, lending or borrowing of any investments;

(d) all taxes, including issuance and transfer taxes, and reserves for taxes payable by the Client to federal, state or other government agencies; and

(e) interest payable on any Account borrowings.

For the avoidance of doubt, the Trading Advisor shall not be responsible for any expenses incurred by the Manager, the Trust or the Accounts.

5. Fees. For all of the services rendered with respect to the Account as herein provided, the Manager shall pay to Trading Advisor the fees as set forth in Exhibit C, as amended from time to time.

6. Standard of Care; Limitation on Liability. For the purpose of this Section 6, the term “Trading Advisor” is deemed to include the Trading Advisor, its affiliates, and each of their respective officers, directors, employees and agents.

(a) The Trading Advisor shall comply with all applicable laws and regulations in the discharge of its duties under this Agreement. Except as may otherwise be provided by law, Trading Advisor shall not be liable to the Trust or Manager for any error of judgment or for any loss suffered by the Trust or Manager in connection with the subject matter of this Agreement, provided that Trading Advisor acted in good faith and with that degree of care, skill, prudence and diligence under the circumstances then prevailing that a prudent person acting in a similar capacity would use and except for any such losses arising from the gross negligence, willful misconduct or fraud in the performance or non-performance by Trading Advisor of its obligations or duties hereunder.

(b) The Trading Advisor is not liable for any actions that occurred or failed to occur, or any records created or retained, prior to the effective date of this Agreement. The Trading Advisor shall reasonably rely on information provided to it about an Account or the books and records of an Account, if any, that is provided by the Manager, and will not have a duty to confirm such information from any source, including from records it may receive that were created prior to the effective date of this Agreement.

(c) Neither party shall be liable to the other for any special, indirect, punitive, incidental or consequential damages of any nature whatsoever arising from any act or omission of the other party, whether or not the possibility of such damage was disclosed to, or could have been reasonably foreseen by, such party. Without prejudice to the generality of the foregoing, neither party shall be liable under or in connection with this Agreement for (a) loss (whether direct or indirect) of business profits, revenue or of data; or (b) any indirect, consequential or incidental damages, liabilities, claims, losses, expenses, awards, proceedings and costs, in each case which may be suffered by a party, the Manager, the Trust, or any third party regardless of whether the possibility of such damages, liabilities, claims, losses, expenses, awards, proceedings and costs was disclosed to, or could reasonably have been foreseen and whether arising in contract, in tort or otherwise.

(d) Trading Advisor will not be liable for any claim or damages due to the failure to perform by a third party including, without limitation, loss or damage to Manager or Account documentation or property, or errors or inaccuracies from any pricing source.

(e) Trading Advisor shall not be liable for any action taken, delay or any failure to take any action required to be taken hereunder or otherwise to fulfill its obligations hereunder (including without limitation loss, delay or mis-delivery or error in transmission of communications or financial information) in the event and to the extent that the taking of such action, delay or such failure arises out of or is caused by or directly or indirectly due to war, act of terrorism, insurrection, riot, labor disputes, civil commotion, act of God, pandemic, accident, fire, water damage, explosion, any law, decree, regulation or order of any government or governmental body (including any court or tribunal), or any other cause (whether similar or dissimilar to any of the foregoing) whatsoever beyond its reasonable control or the reasonable control of any delegate or securities system. In any such event, Trading Advisor shall be excused from any further performance and observance of the obligations so affected only for so long as such circumstances prevail and the Trading Advisor continues to use commercially reasonable efforts to recommence performance or observance as soon as practicable.

7. Indemnification.

(a) Except as stated in Section 7(b), below, in the absence of gross negligence, willful misconduct or fraud on the part of the Trading Advisor, none of the Trading Advisor, its affiliates or their respective officers, controlling persons, members, partners, shareholders, agents or employees (each, an “Indemnified Person” and collectively, the “Indemnified Persons”) shall be subject to any liability to the Manager for any act or omission in the course of, or connected with, rendering services hereunder. The Trading Advisor does not guarantee the future performance of the Account or any specific level of performance, the success of any investment decision or strategy that Trading Advisor may use, or the success of Trading Advisor’s overall management of the Account. Manager understands that investment decisions made for the Account by Trading Advisor are subject to various market, currency, economic, political and business risks, and that those investment decisions will not always be profitable. Trading Advisor will manage only the Account Allocation and in making investment decisions for the Account, Trading Advisor will not consider any other securities, cash or other investments owned by the Trust.

(b) Trading Advisor agrees to indemnify the Manager, its affiliates, officers, controlling persons, agents, and employees for, and hold it harmless against, any and all losses, claims, damages, liabilities (including amounts paid in settlement with the written consent of Trading Advisor) or litigation (including reasonable legal and other expenses) (“Losses”) to which the Manager may become subject as a direct result of (i) any disclosure in the Registration Statement of the Fund about Trading Advisor that has been specifically approved by Trading Advisor, (ii) Trading Advisor’s gross negligence, willful misconduct or fraud in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement, or (iii) a breach of the representations provided in Section 11(d) or Section 11(e) of this Agreement; provided, however, that nothing contained herein shall require that Manager be indemnified for Losses that resulted from the Manager’s gross negligence, willful misconduct or fraud in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement; further provided that Trading Advisor shall have been given written notice concerning any matter for which indemnification is claimed under this Section.

(c) Manager agrees to indemnify the Indemnified Persons for, and hold each Indemnified Person harmless against, any and all Losses to which such Indemnified Person may become subject as a direct result of this Agreement or Trading Advisor’s performance of its duties hereunder; provided, however, that nothing contained herein shall require that Trading Advisor be indemnified for Losses that resulted from (i) any disclosure in the Registration Statement of the Fund about Trading Advisor that has been specifically approved by Trading Advisor, (ii) Trading Advisor’s gross negligence, willful misconduct or fraud in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement, or (iii) a breach of the representations provided in Section 10(d) or Section 10(f) of this Agreement; provided that the Manager shall have been given written notice concerning any matter for which indemnification is claimed under this Section.

8. Confidentiality.

(a) Trading Advisor agrees to hold confidential any non-public or proprietary information of Manager and Trust supplied in connection with the opening of an Account and the trading of the assets of an Account. Trading Advisor further acknowledges that Trading Advisor may come into contact with information concerning Manager or its affiliates and/or personnel, or information concerning the Trust, and Trading Advisor agrees that it will not communicate, disclose or utilize for its own benefit or for the benefit of any other entity or persons, any and all information that is not in the public domain with regard to Manager and/or its affiliates and/or personnel, or with regard to the Trust. All of the foregoing referred to in this Section above shall be collectively referred to as “Confidential Information.”

(b) Trading Advisor agrees that it will not (i) use such Confidential Information except in connection with investment activities for the appropriate Accounts or (ii) disclose any Confidential Information without Manager’s consent to any third person (unless required to do so by law, regulation or at the request of any regulatory or self-regulatory authority).

(c) It is expressly agreed that among the various remedies for violation of this Section shall be specific performance and injunctive relief issued by any court having jurisdiction over these matters.

9. Non-Exclusivity; No Partnership.

(a) The services of Trading Advisor to the Manager and the Account are not to be deemed exclusive and Trading Advisor shall be free to render similar services to others so long as its services hereunder are not impaired thereby. It is specifically understood that Trading Advisor and each Indemnified Person may continue to engage in providing portfolio management services and advice to other investment advisory clients. The Manager agrees that Trading Advisor and each Indemnified Person may give advice and take action in the performance of its duties with respect to any of the Trading Advisor’s or Indemnified Person’s other clients which may differ from advice given or the timing or nature of action taken with respect to the Account. Trading Advisor and the Indemnified Persons, however, shall not provide investment advice to any assets of the Trust other than the Account Allocation. Nothing in this Agreement shall be deemed to require Trading Advisor or any Indemnified Person to purchase or sell for the Account Allocation of Client any Commodity Interest or other property which the Trading Advisor or any Indemnified Person may purchase or sell for its or their own account or for the account of any other client, unless required by the applicable Guidelines.

(b) It is understood and agreed that Trading Advisor shall be deemed to be an independent contractor of Manager and the Trust and, except as otherwise set forth herein, that Trading Advisor shall not have authority to act for or represent Manager or the Trust in any way and shall not otherwise be deemed to be Trust’s or Manager’s agent. Nothing contained herein shall create or constitute the Trust, Manager and Trading Advisor as members of any partnership, joint venture, association, syndicate, unincorporated business, or other separate entity, nor shall be deemed to confer on any of them any express, implied, or apparent authority to incur any obligation or liability on behalf of any other such entity.
