Ladies and Gentlemen:

This agreement (the “Agreement”) is between Calamos Advisors LLC (including any successor or assign by merger or otherwise, the “Company”) and RBC Capital Markets, LLC (“RBCCM”) with respect to the Calamos Long/Short Equity & Dynamic Income Trust (the “Fund”). Capitalized terms used herein and not otherwise defined shall have the meanings given to them in the underwriting agreement (the “Underwriting Agreement”) relating to the Offering (as defined below).

1. Fee. In consideration of certain financial advisory services that RBCCM has provided to the Company in assisting the Company in structuring, designing and organizing the Fund as well as services related to the sale and distribution of the Shares of the Fund (the “Offering”), it being understood that the ultimate decision with respect to the structure, design and organization of the Fund shall rest with the Company and the Fund’s Board of Trustees, the Company shall pay a fee to RBCCM in the aggregate amount of $[•] (the “Fee”). The Fee shall be paid on or before [•], 2019 or as otherwise agreed to by the parties. In the event the Offering does not proceed, RBCCM will not receive any fees under this Agreement; however, for the avoidance of doubt, accountable expenses actually incurred may be payable to RBCCM pursuant to the terms of the Underwriting Agreement.

2. Term. This Agreement shall terminate upon the payment of the entire amount of the Fee, as specified in Section 1 hereof. Notwithstanding the foregoing, Sections 4, 5, 8, 9 and 10 of this Agreement and the Indemnification Agreement attached hereto shall survive the termination of this Agreement.

4. Confidential Advice. Except to the extent legally required (after consultation with, and approval as to form and substance by, RBCCM and its counsel), none of (i) the name of RBCCM, (ii) any advice rendered by RBCCM to the Company, or (iii) the terms of this Agreement (but not the existence of this Agreement) or any communication from RBCCM, each in connection with the services performed by RBCCM pursuant to this Agreement, will be quoted or referred to orally or in writing, or in the case of (ii) and (iii), reproduced or disseminated, by the Company or any of its affiliates or any of its agents, without RBCCM’s prior written consent, which consent will not be unreasonably withheld in the case of clause (i) and (iii) (but not (ii)); provided, however, that this provision shall not be applicable to: (A) any information (except for the information in clause (ii)) that becomes publicly available through no fault of the Company; or

(B) any information covered by each of clauses (i), (ii) and (iii) above, the release of which is required or requested by a regulatory agency, self-regulatory organization, or court with jurisdiction over the Company or its affiliates, provided, however, that the Company will promptly notify RBCCM of the information to be disclosed if notice thereof is permitted by law, does not violate the terms of the relevant request and is reasonably practicable under the circumstances.

5. Information. The Company recognizes and confirms that RBCCM (a) has used and relied primarily on the information provided by the Company and on information available from generally recognized public sources in performing the services contemplated by this Agreement without having assumed responsibility for independently verifying the same, (b) has not assumed responsibility for the accuracy, completeness or reasonableness of such information and (c) has not made an appraisal of any assets or liabilities (contingent or otherwise) of the Fund.

6. Not an Investment Adviser. The Company acknowledges that RBCCM has not provided any advice hereunder as to the value of securities or regarding the advisability of purchasing or selling any securities for the Fund’s portfolio. The Company acknowledges and agrees that RBCCM has been retained to act solely as an adviser to the Company, and the Company’s engagement of RBCCM is not intended to confer rights upon any person (including the Fund or any shareholders, employees or creditors of the Company or the Fund) not a party hereto as against RBCCM or its affiliates, or their respective directors, officers, employees or agents, successors, or assigns. RBCCM has acted as an independent contractor under this Agreement, and not in any other capacity including as a fiduciary, and any duties arising out of its engagement shall be owed solely to the Company.

7. Not Exclusive. Nothing herein shall be construed as prohibiting you or your affiliates from acting as an underwriter or financial adviser or in any other capacity for any other persons (including other registered investment companies or other investment managers).

8. Amendment; Waiver. No provision of this Agreement may be amended or waived except by an instrument in writing signed by the parties hereto.

9. Governing Law.

No Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have exclusive jurisdiction over the adjudication of such matters, and the Company and RBCCM consent to the jurisdiction of such courts and personal service with respect thereto. EACH OF RBCCM AND THE COMPANY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING OR CLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR IN ANY WAY RELATING TO THIS AGREEMENT.
