As previously disclosed, on April 22, 2014, Banc of California, Inc. (the “Company”) entered into two separate Securities Purchase Agreements (collectively, the “SPAs”), one with OCM BOCA Investor, LLC (“Oaktree”), an entity owned by investment funds managed by Oaktree Capital Management, L.P., and one with Patriot Financial Partners, L.P. and Patriot Financial Partners Parallel, L.P. (together, “Patriot Partners”), to raise a portion of the capital to be used to finance the previously announced acquisition of select assets and assumption of certain liabilities comprising Banco Popular North America’s (“BPNA”) network of 20 California branches pursuant to the Purchase and Assumption Agreement, dated as of April 22, 2014, by and between BPNA and Banc of California, National Association, a wholly owned subsidiary of the Company (the “Branch Acquisition”).

New Patriot SPA

The SPA with Patriot Partners was due to expire by its terms at the end of the day on October 31, 2014. Prior to such expiration, the Company and Patriot Partners, Patriot Financial Partners II, L.P. and Patriot Financial Partners Parallel II, L.P. (collectively, “Patriot”) entered into a Securities Purchase Agreement, dated as of October 30, 2014 (the “New Patriot SPA”), which provides that, at the closing of the sale of shares contemplated thereby, Patriot will simultaneously purchase from the Company (i) 1,076,000 shares of its voting common stock at a price of $9.78 per share and (ii) 824,000 shares of its voting common stock at a price of $11.55 per share, for an aggregate purchase price of $20,040,480. In consideration for Patriot’s commitment under the New Patriot SPA, the Company agreed to pay to Patriot at the closing of the sale of shares contemplated thereby an equity support payment of $538,000.

The New Patriot SPA contains customary representations and warranties from the Company and Patriot. The parties have agreed to customary closing conditions and covenants, and the Company has undertaken certain customary indemnification obligations.

Pursuant to the New Patriot SPA, the prior SPA with Patriot Partners was terminated in its entirety. The closing of the sale of shares contemplated by the New Patriot SPA is expected to occur substantially concurrently with the closing of the Branch Acquisition, which is expected to occur on November 7, 2014.

Oaktree Amendment

Pursuant to the SPA with Oaktree, the Company agreed to sell a number of shares of its voting common stock to Oaktree such that the percentage of the outstanding shares of the Company’s voting common stock owned by Oaktree immediately following the closing of such sale will equal 9.9%. The Company also agreed to pay to Oaktree at the closing an equity support payment of $0.50 per share for each share purchased pursuant to the SPA. However, the SPA with Oaktree was also due to expire by its terms at the end of the day on October 31, 2014. On October 28, 2014, the Company amended its SPA with Oaktree by entering into an Acknowledgement and Amendment to Securities Purchase Agreement (the “Oaktree Amendment”), pursuant to which the parties agreed that the Purchase Price Per Share (as defined in the SPA with Oaktree) will be $9.78 per share, and that the number of shares of voting common stock to be purchased by Oaktree pursuant to the SPA is expected to be 3,287,954 shares, subject to confirmation at closing. The Oaktree Amendment also extended the outside termination date to December 15, 2014. The SPA with Oaktree provides that the closing of the sale of shares contemplated thereby will occur substantially concurrently with the closing of the Branch Acquisition.

The foregoing description of the SPAs, the New Patriot SPA and the Oaktree Amendment and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to (i) the SPAs, which are attached as Exhibit 10.1 and Exhibit 10.2 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on April 25, 2014, and (ii) the New Patriot SPA and the Oaktree Amendment, which are attached as Exhibit 10.1 and 10.2 hereto, respectively, and all of which are incorporated into this Current Report on Form 8-K by reference. Except for its status as a contractual document that establishes and governs the legal relations among the parties with respect to the transactions described therein, none of the SPAs, the New Patriot SPA nor the Oaktree Amendment is intended to be a source of factual, business or operational information about the parties thereto. Representations and warranties may be used as a tool to allocate risks between the parties to such agreements, including where the parties do not have complete knowledge of all facts, instead of establishing these matters as facts. Furthermore, representations and warranties may be subject to standards of materiality applicable to the contracting parties, which may differ from those applicable to investors.

On October 30, 2014, the Company announced that it will host a conference call at 8:00 a.m. PST (11:00 a.m. EST) on October 30, 2014 to discuss its operating results for the three and nine months ended September 30, 2014 and other matters.

A copy of the presentation materials to be discussed during the conference call will be made available prior to the call on the Company’s website and is attached hereto as Exhibit 99.2.
