Item 5.  Other Events.

         On December 27, 2001, Acterna LLC ("Acterna LLC"), a Delaware limited
liability company that is wholly-owned and controlled by Acterna Corporation
("Acterna"), agreed to issue and sell (such issuance and sale, the
"Transaction") $75,000,000 aggregate principal amount of 12% Senior Secured
Convertible Notes Due 2007 (the "Notes") to Clayton, Dubilier & Rice Fund VI
Limited Partnership (the "Investor") on the terms and conditions set forth in an
Investment Agreement, dated as of December 27, 2001 (the "Investment
Agreement"), among Acterna, Acterna LLC and the Investor. A copy of the
Investment Agreement, as well as a copy of the Form of Note issuable under the
Investment Agreement, are filed as exhibits to this Form 8-K.

         The Investor and Clayton, Dubilier & Rice Fund V Limited Partnership
("CD&R Fund V") together own approximately 80% of Acterna's outstanding common
stock and are jointly managed by Clayton, Dubilier & Rice, Inc. As a result of
this relationship, a special committee of independent directors of Acterna
evaluated the terms of the Transaction and unanimously determined that such
terms were fair to Acterna from a financial point of view. The Transaction
closed on January 15, 2002.




         The material terms of the Notes are as follows:

         o      Interest and Maturity. The Notes bear interest at a rate per
                annum of 12% and mature on December 31, 2007 (the "Maturity
                Date"). Interest on the Notes is payable semi-annually in
                arrears on each March 31st and September 30th, with interest
                payments commencing on March 31, 2002. At the option of Acterna
                LLC, interest is payable in cash or in-kind by the issuance of
                additional Notes. Due to limitations imposed by its senior
                secured credit facility, as amended (see below), Acterna LLC
                expects to pay interest on the Notes in-kind by issuing
                additional Notes.

         o      Conversion. Subject to prior approval of Acterna's stockholders
                (as described below), at the option of the Investor (or any
                subsequent holder of Notes), at any time prior to the Maturity
                Date, the Notes may be converted into newly-issued shares of the
                common stock, par value $0.01 per share, of Acterna (the "Common
                Stock"), at a conversion price (the "Conversion Price") of $3.00
                per share, subject to customary antidilution adjustments.

         o      Redemption, Repurchase or Repayment; Issuance of Warrants.
                Acterna LLC may redeem the Notes, in whole or in part, and
                without penalty or premium, at any time prior to the Maturity
                Date. In addition, Acterna LLC is required to offer to
                repurchase the Notes upon a change of control and upon the
                disposition of certain assets. If any Note is redeemed,
                repurchased or repaid for any reason prior to the Maturity Date,
                the holder thereof will be entitled to receive from Acterna a
                warrant (a "Warrant") to purchase a number of newly-issued
                shares of Common Stock equal to the number of shares of Common
                Stock that such Note was convertible into immediately prior its
                redemption, repurchase or repayment. The exercise price of such
                Warrant will be the Conversion Price in effect immediately prior
                to such Warrant's issuance, subject to customary antidilution
                adjustments. Subject to the approval of Acterna's stockholders
                (as described below), Warrants will be exerciseable upon
                issuance and will expire on the Maturity Date. A copy of the
                Form of Warrant issuable under the Investment Agreement is filed
                as an exhibit to this Form 8-K.

         o      Conversion of Notes and Exercise of Warrants Subject to
                Stockholder Vote. In order to comply with the rules of the
                Nasdaq National Market, where the Common Stock is listed, the
                terms of the Notes and Warrants provide that no Note or Warrant
                may be converted or exercised, as the case may be, until the
                stockholders of Acterna have approved the issuance of the shares
                of Common Stock upon such conversion or exercise. Acterna
                expects to obtain such approval by obtaining the written consent
                of its stockholders. Without giving effect to the Transaction,
                the Investor and CD&R Fund V collectively own approximately 80%
                of the outstanding Common Stock. Each has indicated that it
                intends to vote its shares in favor of the

                                       2








                Transaction, thereby assuring that Acterna will receive the
                stockholder approval necessary to comply with the Nasdaq rules.

         o      Registration Rights. Shares of Common Stock issuable upon the
                conversion of Notes or exercise of Warrants will have the same
                registration rights as the shares of Common Stock currently held
                by the Investor and CD&R Fund V. A copy of an amendment to the
                existing Registration Rights Agreement is filed as an exhibit to
                this Form 8-K.

         o      Covenants and Restrictions. While Acterna remains subject to the
                financial covenants under its senior secured credit facility,
                the Investment Agreement and the Notes do not impose any
                additional financial covenants. However, under the Investment
                Agreement and the Notes, Acterna and its subsidiaries will be
                subject to certain affirmative covenants, which are
                substantially the same as those under its senior secured credit
                facility, and certain negative covenants, which are
                substantially the same as those contained in the indenture for
                the 9.75% Senior Subordinated Notes Due 2008 of Acterna LLC.

         o      Security. The Notes are secured by liens on certain of the
                property and assets of, and guarantees by, Acterna and its
                subsidiaries. The security interests of the holders of the Notes
                are second in priority to those of the lenders under Acterna's
                senior secured credit facility.

         Concurrently with its agreement to the Transaction, Acterna entered
into an amendment to the Credit Agreement governing its senior secured credit
facility. Under the amendment, the lenders under the Credit Agreement, among
other things, agreed to waive for a specified period certain of the financial
covenants of Acterna under the Credit Agreement and consented to the
Transaction, and Acterna became subject to certain additional covenants and
restrictions, including, without limitation, new minimum liquidity and EBITDA
requirements and additional restrictions on Acterna's ability to make capital
expenditures, incur and guarantee debt, make investments, optionally prepay the
9.75% Senior Subordinated Notes Due 2008 of Acterna LLC and dispose of assets.
The amendment also, among other things, adds additional prepayment requirements,
establishes additional guarantees and pledges of collateral and increases the
interest rates on loans under the senior secured credit facility by 0.75%. A
copy of the amendment is filed as an exhibit to this Form 8-K.
