Corporate Performance Plan For 2017

CORNING INCORPORATED

CASH PERFORMANCE UNIT AGREEMENT

(Terms and Conditions)

Important Change: 100% of the awards offered under the executive long-term incentive plan for 2017 are contingent on Employee accepting the terms and conditions of a Non-Compete Agreement attached as Appendix A to the 2017 Restricted Stock Unit Agreement before May 31, 2017.  Failure to accept these terms and conditions will result in the forfeiture and cancellation of 100% of the awards offered.

This Cash Performance Unit Agreement ("Agreement") dated February 1, 2017 between Corning Incorporated (the "Company") and the employee (the "Employee") is subject in all respects to the Company's 2012 Long-Term Incentive Plan as amended from time to time (the "Plan"), a copy of which may be obtained from the Company's Secretary at One Riverfront Plaza, Corning, New York  14831.  Capitalized terms not otherwise defined herein shall have the meaning ascribed thereto in the Plan.

1.	Award of Units.  Each Cash Unit shall entitle the Employee to receive from the Company an amount equal to $1 (one US Dollar). The Cash Units, if any, shall be paid to the Employee at the time set forth in Section 6 and in the manner set forth in Section 7 provided that both the "Performance-Based Vesting Requirement" set forth in Section 3 and the "Service Based Vesting Requirement" set forth in Section 4 are satisfied.  Prior to vesting pursuant to Sections 3 and 4, the Cash Units shall not be earned and shall remain subject to forfeiture.
2.	Non-Transferability.  The Cash Units may not be sold, assigned, transferred, pledged or otherwise encumbered by or on behalf of or for the benefit of the Employee other than by last will and testament, by the laws of descent and distribution, pursuant to a domestic relations order or as otherwise permitted by the Committee pursuant to Section 12 of the Plan.
3.	Performance-Based Vesting Requirement.
	(a)	Within ninety days following the beginning of each fiscal year ending on December 31st 2017, 2018 and 2019 (each such year, an "Annual Performance Period" and collectively, the "Performance Period"), the Compensation Committee of the Company's Board of Directors (the "Committee") shall determine performance targets (each a "Performance Target") applicable to the current fiscal year.  Such targets will be communicated annually to the Employee.
		For purposes of determining the number of Cash Units that the Employee will earn at the end of the Performance Period, performance will be calculated as the simple average of the actual level of attainment of the Performance Targets for each Annual Performance Period as determined by the Committee.  Any Cash Units that are not earned pursuant to Sections 3 and 4 at the end of the Performance Period shall be forfeited.
	(b)	Any Cash Units that are earned pursuant to Sections 3 and 4 (after taking into account the proration adjustments referenced in Section 4 (the "Proration Factor"), if applicable) shall be referred to as the "Earned Units," provided, however, that if the numerator of the Proration Factor is less than 3, all Cash Units shall be forfeited upon a termination of employment for any reason.
4.	Service Based Vesting Requirement.  Subject to the exceptions set forth below, the Employee must remain in continuous employment with the Company Group until the expiration of the Performance Period in order to vest in the Earned Units.  If the Employee's employment with the Company Group terminates on or before the expiration of the Performance Period, any Earned Units shall be treated in the manner set forth in this Section 4.

10.	Transfers.

11.	Section 409A.
	(a)	The Cash Units are intended to comply with or be exempt from Section 409A of the Code and shall be administered and interpreted in accordance with that intent.  If any provision of the Plan or this Agreement would, in the reasonable good faith judgment of the Committee, result or likely result in the imposition on the Employee of a penalty tax under Section 409A, the Committee may modify the terms of the Plan or this Agreement, without the consent of the Employee, in the manner that the Committee may reasonably and in good faith determine to be necessary or advisable to avoid the imposition of such penalty tax.  This Section 11 does not create an obligation on the part of the Company to modify the Plan or this Agreement and does not guarantee that the Cash Units will not be subject to taxes, interest and penalties under Section 409A.
	(b)	Notwithstanding anything to the contrary in the Plan or this Agreement, to the extent that the Cash Units constitute deferred compensation for purposes of Section 409A and the Employee is a "Specified Employee" (within the meaning of the Committee's established methodology for determining "Specified Employees" for purposes of Section 409A), no payment or distribution of any amounts with respect to the Cash Units that are subject to Section 409A may be made before the 15th day of the seventh month following the Employee's "Separation from Service" from the Company (as defined in Section 409A) or, if earlier, the date of the Employee's death.
	(c)	The actual Payment Date pursuant to Section 6 shall be within the sole discretion of the Company.  In no event may the Employee be permitted to control the year in which settlement occurs.
12.	Modification/Interpretation.  The Committee shall have the power to alter, amend, modify or terminate the Plan or this Agreement at any time; provided, however, that no such termination, amendment or modification may adversely affect, in any material respect, the Employee's  rights under this Agreement without the Employee's consent.  Notwithstanding the foregoing, the Company shall have broad authority to amend this Agreement without the consent of the Employee to the extent it deems necessary or desirable (a) to comply with or take into account changes in or interpretations of, applicable tax laws, securities laws, employment laws, accounting rules and other applicable laws, rules and regulations, (b) to take into account unusual or nonrecurring events or market conditions, or (c) to take into account significant acquisitions or dispositions of assets or other property by the Company.  Any amendment, modification or termination shall, upon adoption, become and be binding on all persons affected thereby without requirement for consent or other action with respect thereto by any such person.  The Committee shall give written notice to the Employee of any such amendment, modification or termination as promptly as practicable after the adoption thereof.  The foregoing shall not restrict the ability of the Employee and the Company by mutual consent to alter or amend the terms of the Cash Units in any manner that is consistent with the Plan and approved by the Committee.
13.	Headings.  The headings of sections and subsections are included solely for convenience of reference and shall not affect the meaning of the provisions of this Agreement.
14.	Counterparts.  This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

15.	Entire Agreement.  This Agreement and the Plan constitute the entire agreement between the parties hereto with regard to the subject matter hereof.  They supersede all other agreements, representations or understandings (whether oral or written and whether express or implied) that relate to the subject matter hereof.
16.	Governing Law.  Except as to matters of federal law, this Agreement and all actions taken thereunder shall be governed by and construed in accordance with the laws of the State of New York  (other than its conflict of law rules).
