                               EXPLANATORY NOTE
                  POST-EFFECTIVE AMENDMENT NO. 1 TO FORM S-8

     This post-effective amendment is being filed pursuant to Rule 414 under the
Securities Exchange Act of 1933, as amended (the "Securities Act"), to reflect
the creation by Northrop Grumman Systems Corporation (formerly Northrop Grumman
Corporation), a Delaware corporation ("Systems"), of a new holding company,
Northrop Grumman Corporation (formerly NNG, Inc.) a Delaware corporation ("New
Northrop Grumman"), above Systems. The creation of New Northrop Grumman was
effected pursuant to an Amended and Restated Agreement and Plan of Merger (the
"Amended Merger Agreement"), dated January 23, 2001, among New Northrop Grumman,
Systems, Litton Industries, Inc., a Delaware corporation ("Litton") and LII
Acquisition Corp., a Delaware corporation and wholly owned subsidiary of New
Northrop Grumman ("LII").

     As contemplated by the Amended Merger Agreement, on April 2, 2001, Systems
completed a corporate reorganization (the "Northrop Reorganization") that was
effected by action of its Board of Directors without a vote of Systems'
stockholders, pursuant to Section 251(g) of the Delaware General Corporation Law
(the "DGCL") and an Agreement and Plan of Merger, dated as of March 20, 2001
(the "Merger Agreement"), between Systems, New Northrop Grumman and NGC
Acquisition Corp., a Delaware corporation and indirect wholly-owned subsidiary
of Systems ("NGC"). In the Northrop Reorganization, NGC was merged with and into
Systems, with Systems as the surviving corporation and a wholly-owned subsidiary
of New Northrop Grumman, the new holding company. Pursuant to the requirements
of Section 251(g) of the DGCL, at the effective time of that merger and in
connection with the Northrop Reorganization, New Northrop Grumman changed its
name from NNG, Inc. to "Northrop Grumman Corporation," and Systems changed its
name to "Northrop Grumman Systems Corporation." Upon consummation of the
Northrop Reorganization and in accordance with Section 251(g) of the DGCL, (a)
all of the outstanding shares of capital stock of Systems were automatically
converted into the same number of shares of the same class of capital stock of
New Northrop Grumman, and (b) each certificate representing shares of Northrop
capital stock, without any action on the part of the holder thereof, is now
deemed to represent an equal number of shares of the same class of capital stock
of New Northrop Grumman.

     In accordance with Rule 414 under the Securities Act, New Northrop Grumman,
as the successor issuer to Systems, hereby expressly adopts this registration
statement as its own for all purposes of the Securities Act and the Securities
Exchange Act of 1934, as amended. The Northrop Grumman 1993 Long-Term Incentive
Stock Plan shall continue to be known as the Northrop Grumman 1993 Long-Term
Incentive Stock Plan and the 1993 Stock Plan for Non-Employee Directors will
continue to be known as the 1993 Stock Plan for Non-Employee Directors
(collectively, the "Plans"). The Plans shall continue to cover employees of
Systems. However, shares of stock issued in accordance with the Plan shall be
shares of stock of the New Northrop Grumman rather than shares of stock of
Systems.

     The applicable registration fees were paid at the time of the original
filing of this registration statement.
