Dear Lewis:

As a result of your interviews with Corning, we are pleased to offer you a position as Senior Vice President and General Counsel reporting to Wendell Weeks. In this role, you will be a member of the Management Committee and an SEC 16b officer of Corning. Your work location will be Corning, NY starting on or around June 3, 2013.

Base Salary & Annual Cash Bonuses

Your initial salary will be $580,000 per year, payable bi-weekly. Executive salary reviews are currently scheduled to occur around July 1 each year; your first scheduled review will occur in July 2014.

In addition to your base salary, you will be eligible to participate in a Corning GoalSharing Bonus Program, which is based on the corporate average of all such plans in Corning. Annual cash awards earned under the program may range from 0% to 10% of your base salary. In general, this annual bonus will be pro-rated for your first year of employment and paid in February to participants who are employed by Corning on December 31 of the prior year, in accordance with Corning’s GoalSharing policies.

You will also be eligible to participate in the Performance Incentive Plan. As a member of the Management Committee, this cash bonus plan is based 100% on corporate financial performance. Your annual target opportunity will be 70% of your base salary. Your actual cash award amount may range between 0% and 200% of target and will be pro-rated for time worked during your first year of employment. Awards earned under this program will be paid in March to participants who are employed by Corning on December 31 of the prior year, based on plan rules.

Long-Term Incentives

In this role, you will be an executive of Corning. Annual grants of long-term incentives to executives are approved once a year in February. Your total target award under this plan will not be prorated for the 2013 plan year and will be equal to $1,500,000.

The current plan design includes a mix of:

• Cash Performance Units (50% of target award or $750,000)

– Opportunity ranges from 0% to 150% of the cash performance unit target value;

– Tied to corporate financial performance (currently two equally weighted metrics of adjusted EPS and adjusted Operating Cashflow); and

– The plan currently has a one year performance period with any award actually earned subject to restrictions for a further two years until it is paid (scheduled to be February 2016 for the 2013 awards).

• Time-based Restricted Stock Units (25% of target award or $375,000)

– The grant date for this award will be the first business day of the month following your start date with Corning;

– Not tied to performance;

– Vesting occurs after three years (normally scheduled to be February 2016 for other executives receiving the 2013 awards, but the vesting date will be July 2016 for your initial 2013 awards since you will be joining Corning mid-year); and

– The actual number of restricted stock units to be awarded will be based on the target value of this component and the closing price of Corning stock in effect on the grant date.

• Stock Options (25% of target award or $375,000)

– The grant date for this award will be the first business day of the month following your start date with Corning;

– Not tied to performance;

– Vesting occurs 100% after three years; and

– The actual number of stock options to be awarded will be based on the target value of this component, a Black-Scholes value of 35% and the closing price of Corning stock in effect on the grant date.

These long-term incentives are subject to the more complete terms and conditions of the awards which will be distributed to you after your start date with Corning.
