WHEREAS, effective as of 11:59 p.m. Central Time on September 30, 2015, Capital Southwest separated its industrial products, coatings, sealants, and adhesives and specialty chemicals businesses from its other businesses through a spin-off of those businesses to its stockholders, which resulted in the distribution of 100% of the outstanding stock in CSW Industrials, Inc.

WHEREAS, the Capital Southwest Award is being adjusted in connection with the Share Distribution and such adjustment includes granting an incentive option to purchase shares of the common stock of the Company (the “Replacement Award”);

WHEREAS, the Board of Directors of the Company has approved granting Replacement Awards in connection with the Share Distribution; and

WHEREAS, pursuant to Section 23 of the CSW Industrials, Inc. 2015 Equity and Incentive Compensation Plan (the “Plan”), the Company is authorized to issue Replacement Awards to any holder of an equity compensation award granted under the Capital Southwest Plan that remains outstanding immediately prior to the Share Distribution.

NOW, THEREFORE, the Company hereby grants a Replacement Award to the Participant as follows:

The Company hereby awards to the Participant an Option Right under the Plan, for the Option Price and number of Common Shares set forth above, effective as of the Date of Grant specified above. This Option Right is intended to be, and shall be treated as, an “incentive stock option” within the meaning of Section 422 of the Code.

Unless otherwise provided herein, capitalized terms used in this Award Agreement that are defined in the Plan and not defined herein shall have the meanings set forth in the Plan. The terms and conditions of the Option Right granted hereby, to the extent not controlled by the terms and conditions contained in the Plan, are as follows:

The Committee may modify, extend or renew this Option Right or accept its surrender (to the extent not yet exercised) and authorize the granting of a new option in substitution for it (to the extent not yet exercised), subject at all times to the Plan, the Code, and other applicable laws. Notwithstanding the foregoing provisions of this Section 4, no modification shall, without the consent of the Participant, alter to the Participant’s detriment or impair any rights of Participant under this Award Agreement except to the extent permitted under the Plan.

Any notice required to be given pursuant to this Award Agreement or the Plan shall be in writing and shall be deemed to be delivered upon receipt or, in the case of notices by the Company, five (5) days after deposit in the U.S. mail, postage prepaid, addressed to the Participant at the address last provided by the Participant for his or her employee records.

This Award Agreement is made pursuant to the Plan and shall be interpreted to comply therewith. Any provision of this Award Agreement inconsistent with the Plan shall be considered void and replaced with the applicable provision of the Plan.

This Award Agreement, together with the Plan, embodies the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement not expressly set forth in this Award Agreement shall affect or be used to interpret, change or restrict the express terms and provisions of this Award Agreement, provided, however, in any event, this Award Agreement shall be subject to and governed by the Plan.

In the event that one or more of the provisions of this Award Agreement shall be invalidated for any reason by a court of competent jurisdiction, any provision so invalidated shall be deemed to be separable from the other provisions hereof, and the remaining provisions hereof shall continue to be valid and fully enforceable.

The Company may, in its sole discretion, deliver any documents related to this Option Right and the Participant’s participation in the Plan, or future awards that may be granted under the Plan, by electronic means or request the Participant’s consent to participate in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and, if requested, agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

This Award Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same agreement.
