Form of Long-Term Incentive Plan and Share Unit Plan Grant Notice (PSU)

The particulars of the PSUs granted to you under the Celestica [Long Term Incentive Plan (LTIP)] [Share Unit Plan (CSUP)] are outlined on this notification statement (the “Grant”).

All defined terms shall have the meanings set out under the [LTIP] [CSUP], except as otherwise defined below:

(a) Adjusted EPS – Non-GAAP Earnings per Share

(b)“TSR Comparator(s)” mean Celestica Inc. and those companies represented in the S&P Americas BMI Technology Hardware & Equipment Index as at [Insert], provided those companies remain publicly traded on an established U.S. stock exchange for the entire performance period.

(c) “Share Price” means, with respect to each of the TSR Comparators, the average closing share price of the common shares of that TSR Comparator on the NYSE or NASDAQ, as applicable, in each of the months of [Insert].

(d)"Target Number" means the target number of PSUs granted, which is shown in Participant’s Shareworks account.

(e)“Total Shareholder Return" or “TSR” means, with respect to each TSR Comparator:

divided by:

expressed as a percentage.

The extent to which each Participant's PSUs vest shall be determined by the Compensation Committee of the Board of Directors, in its sole discretion as follows:

(a)The main performance measure is Adjusted EPS growth over the performance period.

(b)The Adjusted EPS will be measured on an annual basis for each of the three years of the performance period i.e.,[Insert] respectively.

(c)The Adjusted EPS target for each year will be based on Celestica’s final Annual Operating Plan “AOP” for the performance period.

(d)The Adjusted EPS target and final achievement will be based on the compounded annual Growth Rate “CAGR” of the Adjusted EPS of the full 3 year performance period (i.e., [Insert] Adjusted EPS compared to [Insert] Adjusted EPS)

(e)The percentage of PSUs that will vest as determined by the Adjusted EPS growth can range between zero and 200% of the target number of PSUs issued. The Adjusted EPS growth will then be impacted by the TSR Factor as described below

(f)Celestica’s TSR will be ranked against that of each of the TSR Comparators. The total percentage of PSUs that will vest on [Insert], as determined by the Adjusted EPS growth result will be modified by the TSR factor. For positioning that falls between values listed in the table below, the TSR factor will be pro-rated.

Celestica’s percentile position will be calculated by first arranging the TSR results from highest to lowest for all TSR Comparators, excluding Celestica, and calculating the percentile position for each TSR Comparator. The percentage of PSUs that will actually vest with respect to Celestica’s TSR positioning will be calculated by interpolating between the corresponding payout percentages immediately above and immediately below Celestica’s percentile position.

(g)The maximum number of PSUs that may vest on [Insert] is 200% of the Target Number of PSUs issued. The TSR factor cannot increase the actual number of PSUs that vest to more than 200% of the Target Number.

(h)The total number of PSUs that will actually vest ranges from 0% to 200% of the target number and will be primarily determined by Celestica’s Adjusted EPS result and then modified by Celestica’s Relative TSR achievements (“TSR Factor”) over the performance period. The TSR modifier can be a factor from -30% up to +30%. Note that the TSR modifier is based on the percent of the EPS result.

(i)The total number of PSUs that will actually vest will also be subject to the following conditions:

a.If Celestica’s absolute TSR is positive but below the median of the TSR Comparators, the modifier cannot be negative and will be set to zero (i.e. neutral impact).

b.If Celestica’s absolute TSR is negative yet beats the median of the TSR Comparators that is a deeper negative, the relative TSR modifier cannot be positive and therefore is set at zero (i.e. neutral impact).

c.If Celestica’s absolute TSR is positive and the relative TSR is above the median of the TSR Comparators, while the EPS threshold is not met, a portion of the PSUs will vest in line with the calculated relative TSR modifier which is capped at 30%.

The Board may amend these provisions at any time and from time to time without the consent of any Participant.
