This Second Amendment (this “Amendment”) dated as of March 20, 2017 is between LATTICE STRATEGIES TRUST, HARTFORD EXCHANGE-TRADED FUND TRUST, each a registered management investment company, organized and existing under the laws of California (each a “Trust,” collectively, the “Trusts”), acting on behalf of each of its funds as listed on Schedule B (each a “Fund,” and collectively, the “Funds”), severally and not jointly, and STATE STREET BANK AND TRUST COMPANY acting either directly or through any State Street Affiliate (collectively, “State Street”).

Reference is made to the Securities Lending Authorization Agreement, dated January 26, 2015, as amended (in effect immediately prior to the date of this Amendment, the “Agreement”), between Lattice Strategies Trust and State Street.

Each party hereto represents and warrants that (a) it has the legal right, power and authority to execute and deliver this Amendment, to enter into the transactions contemplated hereby, and to perform its obligations hereunder; (b) it has taken all necessary action to authorize such execution, delivery and performance; and (c) this Amendment constitutes a legal, valid and binding obligation enforceable against it.

5.     Governing Law; Miscellaneous. This Amendment shall be governed and construed in accordance with the governing law of the Agreement. This Amendment may be executed in any number of counterparts, each of which shall be deemed to be an original, but such counterparts, together, constitute only one (1) instrument.
