Explanation of Responses:

1. Total amount includes 23,953 unvested Restricted Performance Stock Rights ("RPSRs") granted under the 2001 Long-Term Incentive Stock Plan ("LTISP") on 2/17/09, with a valuation of performance measurement period ("measurement period") ending on 12/31/11; 34,562 unvested RPSRs granted under the LTISP on 2/16/10, with the measurement period ending on 12/31/12; 16,853 unvested RPSRs granted under the LTISP on 2/15/11, with the measurement period ending on 12/31/13; 16,853 Restricted Stock Rights ("RSRs") granted under the LTISP on 2/15/11 and cliff vests 100% from the fourth anniversary of the grant date on 2/15/15; and 20,224 RSRs granted under the LTISP on 2/15/11 and cliff vests from the fourth anniversary of the grant date on 2/15/15. Grants awarded pursuant to Rule 16b-3(d).

2. Represents the weighted average sale price of $64.83 rounded to the nearest hundredths. The highest price at which the shares sold was $64.96 and the lowest price at which the shares sold was $64.82.

3. Held in the Northrop Grumman Savings and Investment Plan, a qualified profit sharing plan, as of January 28, 2011. Share totals with respect to the Plan are based upon unit accounting and therefore may reflect a decrease in units attributable to an individual though no disposition occurred.

4. The option was first exercisable on 2/17/2010 and it has one remaining annual installment equal to one-third (33%) of the original grant, vesting on 2/17/12.

5. SEP units credited under the Northrop Grumman Savings Excess Plan (the "SEP Plan"), a non-qualified deferred compensation plan, as of March 31, 2011. The value of each unit is based on the price of Issuer common stock, although share totals with respect to the SEP Plan are based upon unit accounting and therefore may reflect a decrease in units attributable to an individual though no disposition occurred.

6. SEP units are payable in cash following termination of the Reporting Person's employment with the Issuer.
