Item 1.01 Entry into a Material Definitive Agreement.

On September 26, 2016, Corporate Capital Trust II (the “Company”) entered into an Amendment (the “Amendment”) to the Expense Support and Conditional Reimbursement Agreement, as previously amended (collectively, the “Expense Support Agreement”) by and among the Company, CNL Fund Advisors II, LLC and KKR Credit Advisors (US) LLC (collectively, the “Advisors”). As previously reported, pursuant to the Expense Support Agreement, the Advisors jointly and severally agreed to pay up to 100% of the Company’s Operating Expenses (as defined in the Expense Support Agreement) until September 30, 2016 (the “Expense Support Payment Period”). Effective as of September 26, 2016, the Amendment extends the Expense Support Payment Period from September 30, 2016 to December 31, 2016.

No other modifications have been made to the terms and conditions of the Expense Support Agreement, as previously amended. The foregoing description is qualified in its entirety by reference to the full text of the Amendment, which is attached hereto as Exhibit 10.1 and incorporated by reference into this Item 1.01 of Form 8-K, and the full text of the Expense Support Agreement, which was previously filed as Exhibit (k)(4) to the Company’s Registration Statement on Form N-2 (File No. 333-199018) filed on October 1, 2015.

Item 8.01 Other Events.

In order to continue to maximize cash available for investment during the launch of the Company, the Advisors have provided written notice to the Company of their agreement to continue to waive all reimbursement of organizational and offering expenses to which they are entitled under the Advisory Agreement and Sub-Advisory Agreement, respectively, in connection with the Company’s gross capital raised before December 31, 2016 (“O&O Reimbursement Waiver”). Accordingly, the Company will not incur charges for organization and offering expenses through the period ending December 31, 2016. The O&O Reimbursement Waiver does not reduce the amount of organization and offering expenses incurred by the Advisors that are eligible for reimbursement in future periods.
