NORTHROP GRUMMAN FINANCIAL SECURITY AND SAVINGS PROGRAM

#### NOTES TO FINANCIAL STATEMENTS

#### 1. DESCRIPTION OF THE PLAN
The following description of the Northrop Grumman Financial Security and Savings Program (the “Plan” or “FSSP”) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan's provisions.

#### General
The Plan is a qualified defined contribution plan established for the benefit of certain employees of Northrop Grumman Corporation (the “Company” or “Plan sponsor”) acquired as part of the Company's acquisition of Litton Industries, Inc. The Plan is closed to new participants and no further contributions are permitted.

The Plan's Benefit Plans Administrative and Investment Committees control and manage the operation of the Plan. State Street Bank and Trust Company (“State Street” or the “Trustee”) serves as the Trustee of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

The Plan holds an interest in the Northrop Grumman Defined Contribution Plans Master Trust (the “DC Master Trust”) through the non-participant directed retirement account (“FSSP Retirement Account”) and the participant directed savings account (“FSSP Savings Account”). It also holds investments in a short-term investment fund at the Trustee.

#### Participant Accounts
Individual accounts are maintained for each Plan participant. Each participant account is credited with an allocation of any Plan earnings from the DC Master Trust. Each participant account is charged with withdrawals and an allocation of any Plan losses and administrative expenses. Allocations are based on participant units. Participants are generally entitled to the net of contributions, withdrawals and allocations to the extent of their vesting in the account.

#### Vesting
Plan participants are fully vested in the balance of their accounts.

#### Investment Options
When participants were eligible to contribute to the Plan, participants could deposit up to 4 percent of eligible compensation into their FSSP Retirement Account which was used as the basis for calculating pension benefits.
