The Audit Committee of the Board of Directors of Northrop Grumman Corporation (the "Company") is organized and established by and among this Board of Directors for the purpose of assisting Board oversight of the accounting and financial reporting processes of the Company, the audits and integrity of the Company's financial statements; the Company's compliance with legal and regulatory requirements related to financial statements and reporting; the Independent Auditor's qualifications and independence; the performance of the Company's internal audit function and performance of the Independent Auditors; the Company's internal control structure; and any other matters relating to the Company's accounting and financial reporting processes.



The Audit Committee shall consist of at least three directors as determined by the Board of Directors, each of whom shall be a non-employee Director of the Company, each of whom shall be independent in accordance with the criteria set forth in Section 10A(m)(3) of the Securities Exchange Act of 1934 as in effect from time to time (including the requirement that director's fees are the only compensation an Audit Committee member may receive from the Company), and at least one of whom shall be a "financial expert" within the meaning of Section 407 of the Sarbanes-Oxley Act of 2002 and the rules issued by the Securities and Exchange Commission ("SEC") pursuant thereto.



The Audit Committee shall meet at least four times annually, or more frequently as circumstances dictate. The Committee shall conduct its meetings with the Vice President of Internal Audit and the Independent Auditors and such other members of management as determined by the Chairman of the Committee. The agenda for each regularly scheduled meeting of the Audit Committee shall provide for the opportunity at the discretion of the Audit Committee for separate sessions, on such terms and conditions as it may elect, severally, with Company management, the Company's Vice President of Internal Audit and his staff, and the Independent Auditor, and for an Executive Session.

A majority of the members of the Audit Committee shall constitute a quorum for any meeting. Any action of a majority of the members of the Audit Committee present at any meeting at which a quorum is present shall be an action of the Audit Committee.


Duties and Responsibilities

The responsibilities of the Audit Committee are to:

1. Review this Charter periodically, at least annually, as conditions dictate and recommend to the Board of Directors any necessary or appropriate amendments.

2. Review and advise on the selection and removal of the Vice President of Internal Audit. Additionally, the Audit Committee will review and recommend changes to the Internal Audit Charter.

3. Appoint, discharge, compensate and oversee the work of the Company's independent audit firm, which, upon the constitution and effectiveness of the Public Company Accounting Oversight Board, shall be a registered public accounting firm as defined by the Sarbanes Oxley Act of 2002 (the "Independent Auditor"), based upon the Committee's judgment of the independence of the auditors (taking into account the standards and rules established by the Public Company Accounting Oversight Board, and fees charged both for preapproved audit and preapproved non-prohibited non-audit services) and the quality of its audit work. The Audit Committee shall be responsible for the resolution of disagreements between management and the Independent Auditor regarding financial reporting. If the Independent Auditor is dismissed by the Audit Committee, the Audit Committee shall appoint a new Independent Auditor. The Audit Committee in its capacity as a committee of the Board of Directors shall determine the appropriate funding for payment of compensation to the Independent Auditor employed for the purpose of issuing an audit report and to any advisers employed by the Audit Committee.

4. Review and preapprove each service, considered to be auditing services and non-prohibited non-audit services to be provided by the Independent Auditor. The Audit Committee may delegate to one or more of its members the authority to grant preapprovals required and as contemplated by Section 10A(i) of the Securities Exchange Act of 1934, with any such preapproval reported to the Audit Committee at its next regularly scheduled meeting.

5. Review with the Independent Auditor and the internal auditors the scope and plan of their respective audits and the degree of coordination of those plans.

6. Meet with the Independent Auditor, who shall report directly to the Audit Committee, to review, among other things, timely reports of all critical accounting policies to be used by the Company, all alternative accounting treatments discussed with management, the ramifications of such treatments and the Independent Auditor's preferred treatment, and all written communications with management, including management letters and any schedule of unadjusted differences, as well as the results of the audit or review and any certification, opinion or report, which the Independent Auditor proposes to render in connection with the Company's financial statements. The review should cover key issues that the Independent Auditor considered during its work, leading to its expression of an opinion or report on the financial statements of the Company and any problems or difficulties related to the audit or review and management's response.

7. Meet with the Vice President of Internal Audit and with management at least once a quarter to review their respective comments concerning the adequacy of the Company's system of internal controls and such other matters as the Audit Committee may deem appropriate.

8.

9. Review, and discuss with management and the Independent Auditor, the Company's audited annual financial statements to be filed with the SEC on SEC Form 10-K and quarterly financial statements on Form 10-Q, including the Management's Discussion and Analysis of Financial Condition and Results of Operations. The Audit Committee shall receive the disclosures by the Company's principal executive officer and principal financial officer regarding the certifications required in each annual or quarterly report filed with the SEC in accordance with the rules regarding such certifications as adopted by the SEC.
