In addition, ~~2017~~the Company and PacWest intend to make available to investors the slides attached hereto as Exhibit 99.2, which are incorporated herein by reference.

~~The~~Item ~~plan was implemented after taking into account the large aggregate strike price of the options and Mr~~9. ~~Rainer’s~~01 ~~ability~~Financial toStatements ~~otherwise exercise the options, as well as the desire for an orderly exercise~~ and sale. The maximum number of shares that may be sold under the plan is 23,333 shares. None of Mr. Rainer’s holdings of CU Bancorp securities other than the expiring stock options are included in the plan. The shares acquired upon exercise by Mr. Rainer will be sold contemporaneously with the exercise.

~~The~~(d ~~transactions~~) ~~under the plan will be disclosed publicly through Form 144 and Form 4 filings with the Securities and Exchange Commission~~Exhibits. Other insiders of the Company may establish stock trading plans under Rule 10b5-1 in the future. Except as may by required by law, the Company does not undertake to report on specific Rule 10b5-1 plans of the Company’s officers or directors, nor to report modifications or terminations of such plans.

Rule 10b5-1 allows insiders to adopt written plans for trading securities in a non-discretionary, pre-scheduled manner in order to avoid concerns about initiating stock transactions when the insider may be aware of non-public information. Such plans also allow insiders to diversify their holdings and to minimize the market effect of stock sales by spreading them out over time.
