In connection with the engagement of Wedbush Securities Inc. (the “Bank”) to advise and assist the undersigned, Nuveen Fund Advisors, LLC (together with its successors and assigns, the “Company”), with respect to the matters set forth in the Fee Agreement dated December 18, 2018 between the Company and the Bank (the “Agreement”), in the event that the Bank, any of its affiliates, each other person, if any, controlling the Bank or any of its affiliates, their respective officers, current and former directors, employees and agents or the successors or assigns of any of the foregoing persons (the Bank and each such other person or entity being referred to as an “Indemnified Party”) becomes involved in any capacity in any claim, suit, action, proceeding, investigation or inquiry (including, without limitation, any shareholder or derivative action or arbitration proceeding) (collectively, a “Proceeding”) with respect to the Agreement, the Company agrees to indemnify, defend and hold each Indemnified Party harmless to the fullest extent permitted by law, from and against any losses, claims, damages, liabilities and expenses, including reasonably incurred fees and expenses of counsel to the Indemnified Parties, with respect to the Agreement, except to the extent that it shall be determined by a court of competent jurisdiction in a judgment that has become final in that it is no longer subject to appeal or other review, that such losses, claims, damages, liabilities and expenses resulted primarily from the bad faith, gross negligence or willful misconduct of such Indemnified Party. In addition, in the event that an Indemnified Party becomes involved in any capacity in any Proceeding with respect to the Agreement, the Company will reimburse such Indemnified Party for reasonable legal and other expenses (including the cost of any investigation and preparation) as such expenses are incurred by such Indemnified Party in connection therewith; provided that in any Proceeding, the Company shall be entitled to select counsel, except that the Indemnified Party shall have the right to select and employ separate counsel (including local counsel), and the Company bear the reasonable fees, costs and expenses as incurred of such separate counsel (and local counsel) only if (i) the use of counsel chosen by the Company to represent the Indemnified Party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such Proceeding include both the Indemnified Party and the Company and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are different from or in addition to those available to the Company, (iii) the Company shall not have employed counsel satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of the institution of such Proceeding or (iv) the Company shall authorize the Indemnified Party to employ separate counsel at the expense of the Company. Promptly as reasonably practicable after receipt by an Indemnified Party of notice of the commencement of any Proceeding, such Indemnified Party will, if a claim in respect thereof is to be made under this paragraph, notify the Company in writing of the commencement thereof; but the failure so to notify the Company (i) will not relieve the Company from liability under this paragraph to the extent it is not materially prejudiced as a

result thereof and (ii) in any event shall not relieve the Company from any liability which it may have otherwise than on account of this Indemnification Agreement. The Company may participate at its own expense in the defense of any such action; provided, however, that counsel to the Company shall not (except with the consent of the Indemnified Parties, which shall not be unreasonably withheld) also be counsel to the Indemnified Parties. The Company will not, without the prior written consent of the Indemnified Parties, which shall not be unreasonably withheld, settle or compromise or consent to the entry of any judgment with respect to any Proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought hereunder (whether or not the Indemnified Parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnified Party from all liability arising out of such Proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party. No Indemnified Party shall, without the prior written consent of the Company (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any Proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought hereunder when the Company is an actual named party thereto, unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnified Party from all liability arising out of such Proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party.

If such indemnification were not to be available for any reason, the Company agrees to contribute to the losses, claims, damages, liabilities and expenses involved (i) in the proportion appropriate to reflect the relative benefits received or sought to be received by the Company and its members and affiliates, on the one hand, and the Indemnified Parties, on the other hand, in the matters contemplated by the Agreement or (ii) if (but only if and to the extent) the allocation provided for in clause (i) is for any reason held unenforceable, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and its members and affiliates, on the one hand, and the Indemnified Parties, on the other hand, as well as any other relevant equitable considerations. The Company agrees that for the purposes of this paragraph the relative benefits received, or sought to be received, by the Company and its members and affiliates, on the one hand, and the Indemnified Parties, on the other hand, of a transaction as contemplated shall be deemed to be in the same proportion that the total value received by or paid to or contemplated to be received by or paid to the Company or its members or affiliates, as the case may be, as a result of or in connection with the transaction (whether or not consummated) for which the Bank has been retained to perform services bears to the fees paid to the Bank under the Agreement; provided, that in no event shall the Company contribute less than the amount necessary to assure that the Indemnified Parties are not liable for losses, claims, damages, liabilities and expenses in excess of the amount of fees actually received by the Bank pursuant to the Agreement. Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission or any other alleged conduct relates to information provided by the Company or other conduct by the Company (or its employees or other agents), on the one hand, or by the Bank, on the other hand. Notwithstanding the provisions of this paragraph, an Indemnified Party shall not be entitled to contribution from the Company if it is determined that such Indemnified Party was guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act of 1933,

as amended) and the Company was not guilty of such fraudulent misrepresentation. The foregoing indemnity and contribution agreement shall be in addition to any rights that any Indemnified Party may have at common law or otherwise.

The Company agrees that no Indemnified Party shall have any liability to the Company or any person asserting claims on behalf of or in right of the Company with respect to the services performed pursuant to and in accordance with the Agreement, except to the extent that it shall be determined by a court of competent jurisdiction in a judgment that has become final in that it is no longer subject to appeal or other review that any losses, claims, damages, liabilities or expenses reasonably incurred by the Company resulted primarily from the bad faith, gross negligence or willful misconduct of the Bank in performing the services that are the subject of the Agreement.

THIS INDEMNIFICATION AGREEMENT AND ANY CLAIM, COUNTERCLAIM OR DISPUTE OF ANY KIND OR NATURE WHATSOEVER WITH RESPECT TO THE SERVICES PERFORMED PURSUANT TO AND IN ACCORDANCE WITH THE AGREEMENT (“CLAIM”), DIRECTLY OR INDIRECTLY, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. THIS INDEMNIFICATION AGREEMENT IS SUBJECT TO THE ARBITRATION PROVISION CONTAINED IN THE AGREEMENT. EACH INDEMNIFIED PARTY 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 INDEMNIFICATION AGREEMENT. EACH PARTY AGREES THAT A FINAL AWARD IN ANY PROCEEDING OR CLAIM ARISING OUT OF OR IN ANY WAY RELATING TO THIS INDEMNIFICATION AGREEMENT SHALL BE CONCLUSIVE AND BINDING UPON SUCH PARTY AND MAY BE ENFORCED IN ANY OTHER COURTS TO THE JURISDICTION OF WHICH SUCH PARTY IS OR MAY BE SUBJECT, BY SUIT UPON SUCH JUDGMENT.

The foregoing Indemnification Agreement shall remain in full force and effect notwithstanding any termination of the Bank’s engagement under the Agreement. This Indemnification Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same agreement.
