Exhibit 10.6

__________________________________________ (the “Employer”) hereby confirms the grant of a Performance Unit Award (“Award”) to the above-named Participant (hereinafter called the “Participant”) pursuant to the 2015 Ashland Inc. Incentive Plan (hereinafter called the “Plan”) (Attachment 1) and this Performance Unit Agreement (International) (“Agreement”), in order to provide the Participant with an additional incentive to continue his/her services to and to continue to work for the best interests of the Employer. The Employer confirms this Award to the Participant, as a matter of separate agreement and not in lieu of salary or any other compensation for services, of the number of Performance Units set forth above, subject to and upon all the terms, provisions and conditions contained herein and in the Long-Term Incentive Plan Program Memorandum (“LTIP”) (Attachment 2) and the Plan. Capitalized terms used but not defined in this Agreement shall have the meanings given such terms in the Plan or the LTIP, as applicable.

1. Performance Unit Award. This Award is granted under, and subject to, all the terms and conditions of the LTIP and the Plan, including, but not limited to, the forfeiture provision of Section 16(H) of the Plan. In consideration of this Award, the Participant agrees that without the written consent of Ashland Inc. (“Ashland”), the Participant will not (i) engage directly or indirectly in any manner or capacity as principal, agent, partner, officer, director, employee or otherwise in any business or activity competitive with the business conducted by Ashland or any of its subsidiaries; or (ii) perform any act or engage in any activity that is detrimental to the best interests of Ashland or any of its subsidiaries, including, without limitation, (aa) solicit or encourage any existing or former employee, director, contractor, consultant, customer or supplier of Ashland or any of its subsidiaries to terminate his, her or its relationship with Ashland or any of its subsidiaries for any reason, or (bb) disclose proprietary or confidential information of Ashland or any of its subsidiaries to third parties or use any such proprietary or confidential information for the benefit of anyone other than Ashland and its subsidiaries (the “Participant Covenants”), provided, however, that section (ii) above shall not be breached in the event that the Participant discloses proprietary or confidential information to the Securities and Exchange Commission, to the extent necessary to report suspected or actual violations of U.S. securities laws, or the Participant’s disclosure of proprietary or confidential information is protected under the whistleblower provisions of any applicable law or regulation. The Participant understands that if he or she makes a disclosure of proprietary or confidential information that is covered above, he or she is not required to inform Ashland, in advance or otherwise, that such disclosure(s) has been made.

Notwithstanding any other provision of the Plan or this Agreement to the contrary, but subject to any applicable laws to the contrary, the Participant agrees that in the event the Participant fails to comply or otherwise breaches any of the Participant Covenants either during the Participant’s employment or within twenty-four (24) months following the Participant’s termination of employment with Ashland or its subsidiaries for any reason: (i) Ashland may eliminate or reduce the amount of any compensation, benefit, or payment otherwise payable by Ashland or any of its subsidiaries (either directly or under any employee benefit or compensation plan, agreement, or arrangement) to or on behalf of the Participant in an amount up to the total amount paid (or closing stock price of Ashland Common Stock on the payment date multiplied by the number of shares of Ashland Common Stock awarded) or payable to the Participant under this Agreement; and/or (ii) Ashland may require the Participant to pay Ashland an amount up to the total amount paid (or closing stock price of Ashland Common Stock on the payment date multiplied by the number of shares of Ashland Common Stock awarded) to the Participant under this Agreement; in each case together with the amount of Ashland’s court costs, attorney fees, and other costs and expenses incurred in connection therewith.

Based upon the attainment of the Performance Goals outlined in the LTIP and the Participant’s continued employment through the last business day of the month prior to the Crediting Date (as defined below) (the “Vesting Date”), this Award of Performance Units will be paid to the Participant solely in cash, in an amount determined by multiplying (x) the number of Performance Units (if any) earned pursuant to this Award, by (y) the Fair Market Value (as defined in the Plan) per share of Ashland Common Stock on the date that attainment of the Performance Goals and payment of this Award is approved in accordance with the LTIP and the Plan (the “Crediting Date”). After the Crediting Date, payment shall be made to the Participant as soon as it is administratively possible and all other conditions hereunder are met.

This Agreement shall not entitle Participant to Ashland Common Stock, or any dividends or distributions on Ashland Common Stock, or any return or interest on the contingent cash compensation provided in this Agreement. The cash compensation shall be calculated in US dollars, but paid in the local currency of the Participant (as soon as administratively possible) based on the prevailing currency conversion rate on the Crediting Date.

(a) If the Change in Control occurs during the first twelve (12) months of the Performance Period, then (I) a pro-rata portion of the Performance Units will become vested as of the date of the Change in Control (and payable within 30 days thereafter), determined by multiplying the target number of Performance Units by a fraction, the numerator of which is the number of days from the first day of the Performance Period through the date of the Change in Control and the denominator of which is the full number of days in the Performance Period; and (II) a pro-rata portion of the Performance Units will be converted to a time-based, cash-settled Restricted Stock Unit award, with the number of such Restricted Stock Units determined by multiplying the target number of Performance Units by a fraction, the numerator of which is the number of days remaining in the Performance Period after the date of the Change in Control

and the denominator of which is the full number of days in the Performance Period, and such Restricted Stock Units will continue to vest, subject to the Participant’s continued employment through the Vesting Date; provided that any such outstanding unvested Restricted Stock Units will immediately vest upon the termination of the Participant’s employment by Ashland without “Cause” (as defined below), and not as a result of the Participant’s Disability or death, during the one-year period beginning on the date of the Change in Control.

(b) If the Change in Control occurs after the first twelve (12) months of the Performance Period, then (I) a pro-rata portion of the Performance Units will become vested as of the date of the Change in Control (and payable within 30 days thereafter), determined by multiplying the number of Performance Units earned based upon actual achievement of the Performance Goals up to the date of the Change in Control by a fraction, the numerator of which is the number of days from the first day of the Performance Period through the date of the Change in Control and the denominator of which is the full number of days in the Performance Period; and (II) a pro-rata portion of the Performance Units will be converted to a time-based, cash-settled Restricted Stock Unit award, with the number of such Restricted Stock Units determined by multiplying the number of Performance Units earned based upon actual achievement of the Performance Goals up to the date of the Change in Control by a fraction, the numerator of which is the number of days remaining in the Performance Period after the date of the Change in Control and the denominator of which is the full number of days in the Performance Period, and such Restricted Stock Units will continue to vest, subject to the Participant’s continued employment through the Vesting Date; provided that any such outstanding unvested Restricted Stock Units will immediately vest upon the termination of the Participant’s employment by Ashland without “Cause” (as defined below), and not as a result of the Participant’s Disability or death, during the one-year period beginning on the date of the Change in Control.

(ii) If the Award is not assumed, continued, converted or replaced by the surviving or resulting entity in connection with the Change in Control, then the Performance Units will immediately vest in full (without pro-ration) upon the date of the Change in Control, based upon (a) the target number of Performance Shares, if the Change in Control occurs during the first twelve (12) months of the Performance Period; or (b) the number of Performance Units earned based upon actual achievement of the Performance Goals up to the date of the Change in Control, if the Change in Control occurs after the first twelve (12) months of the Performance Period, and such vested Performance Units will be payable in cash in an amount determined by multiplying (a) the number of shares of Common Stock related to the vested Performance Units by (b) the Fair Market Value of the Common Stock on the date of the Change in Control.

For purposes of this Agreement, “Cause” shall mean (i) the willful and continued failure of the Participant to substantially perform his or her duties with Ashland or a subsidiary (other than such failure resulting from the Participant’s incapacity due to physical or mental illness), (ii) willful engaging by the Participant in gross misconduct materially injurious to Ashland or a subsidiary, or (iii) the Participant’s conviction of or the entering of a plea of nolo contendre (or similar plea under the law of a jurisdiction outside the United States) to the commission of a felony (or a similar crime or offense under the law of a jurisdiction outside the United States).

Any amount vested and payable pursuant to this Agreement in connection with a Change in Control will be paid in cash within 30 days after such amount becomes vested as provided herein; provided, however, that to the extent necessary to comply with Section 409A of the Code, any such vested amount shall be payable upon the earlier of (i) within 30 days after the Vesting Date; (ii) within 30 days after the Participant’s separation from service (within the meaning of Section 409A of the Code) or, if the Participant is a specified employee (as determined by Ashland in accordance with Section 409A of the Code), within 30 days after the first business day that is at least six months after the Participant’s separation from service; or (iii) within 30 days after the occurrence of a Change in Control that constitutes a “change in control event” within the meaning of Treasury Regulation § 1.409A-3(i)(5).

3. Adjustments. In the event of any change in the outstanding Ashland Common Stock by reason of any stock split, stock dividend, recapitalization, merger, consolidation, reorganization, combination or exchange of shares, split-up, split-off, spin-off, liquidation or other similar change in capitalization, the number of Performance Units under this Agreement shall be automatically adjusted so that the proportionate interest in Ashland Common Stock represented by the Performance Units shall be maintained as before the occurrence of such event. If Ashland Common Stock ceases to be listed on the NYSE prior to the Crediting Date, the Fair Market Value for purposes of this Agreement shall be the closing price for Ashland Common Stock on the NYSE on the last listing day.

5. Effect on Employment. This Agreement is not a contract of employment and it is not a guarantee of employment for life or any period of time. Nothing in this Agreement interferes with or limits in any way the right of the Employer to terminate the Participant’s employment at any time subject to and in accordance with the applicable laws. This Agreement does not give the Participant any right to continue in the employ of the Employer. The Participant acknowledges that he is an employee of the Employer and not an employee of Ashland or any other Ashland affiliate.
