Title and Administration: The plan shall be referred to as the 2013 AIP. The plan will be administered by Novelis Corporate Human Resources.

Performance Year: For this plan the performance period will be April 1, 2012 to March 31, 2013. Payouts, computed on the basis of performance, will be made following necessary approvals.

Eligibility: Employees in bands 11B and above are eligible to participate.

Opportunity: The target opportunity across regions will be in line with market practice and defined to be competitive and motivate employees to drive the desired behavior in the organization.

Measures and application of weights to each measure to be used for computation of the 2013 AIP: Three measures shall be used to compute performance. The three measures are as follows:

Normalized EBITDA: Defined as Net Revenues — COGS without depreciation - S&AE — R&D + Realized G/L on Derivatives. This will carry a 50% weighting on the overall plan.

Operating Free Cash Flow: Defined as Operating EBITDA — CAPEX — Change in Working Capital — Change in Deferred Items. In terms of specifics, the measure of operating free cash flow will be used for the regions and Free Cash Flow (FCF), which includes interest, tax, dividends and corporate costs, will be used for overall Novelis performance. This will carry a 30% weighting on the overall plan.

Individual Performance: This is based on the individual performance rating in the Performance Management System for Novelis. This will carry a 20% weighting in the overall plan.

Mix of business performance impact: Different levels and roles will carry a differential weighting on the basis of line of sight and impact. Some of the weightings will be as follows :

All Corporate Staff, members of the Global Operating Committee, employees in Job Band 2, and Global Value Stream Leaders are 100% based on overall Novelis results.

All other Region staff will be 50% overall Novelis performance and 50% on Region performance.

Performance Measures and Targets for the 2013 AIP: The performance measures, including thresholds, targets and maximums, will be as approved by the Board for FY 2013.

Overall Threshold: No AIP bonus will be paid with respect to Normalized EBITDA, Operating Cash Flow, and Individual Performance components unless overall Novelis Normalized EBITDA for the fiscal year is at least 80% of target. Once the 80% minimum overall Novelis Normalized EBITDA threshold is achieved, the actual payout under each of these three components will range from 50% of target (threshold) to 175% of target (maximum) depending upon the actual results attributable to each such component.

Other aspects of the plan :

Payments will be made in a lump sum during the first quarter following the close of the performance year. An individual needs to either be employed in a 2013 AIP eligible position or transferred or hired into an eligible position during the performance year to receive payout under the AIP.

Eligibility and payouts for employees who join during the plan year will be determined by the “Plan Rules Administration” document maintained by the Corporate Compensation department.

Eligibility and payouts for employees who leave during the plan year will be determined by the “Plan Rules Administration” document maintained by the Compensation department.
