The Schedule 14D-1 filed by PMA Acquisition Corporation, a Delaware corporation, a wholly owned subsidiary of AlliedSignal Inc., a Delaware corporation, in connection with its pending tender offer for up to 20,000,000 shares of common stock, without par value, of AMP Incorporated, a Pennsylvania corporation, is hereby amended as follows: ITEM 10. ADDITIONAL INFORMATION. Item 10 is hereby amended and supplemented by the following: (f) On September 22, 1998, the Company filed a first amended complaint in the Company Action. The first amended complaint alleges: (i) Parent's filings with the SEC are false and misleading because (a) they fail to disclose the manner in which the Nominees would satisfy their duty of undivided loyalty both to Parent and the Company, (b) they fail to disclose the manner in which the Nominees would propose to reconcile the interests of the Company with those of the Parent, (c) they fail to disclose that Parent has stated, that, upon the election of the Nominees, it will discharge all of the Company's senior executives, and (d) they misrepresent that Parent will be able to vote the Shares acquired under the Offer because the Control Share Acquisition Statute prohibits Parent from voting such shares; (ii) the First and Second Supplement to the Offer and the Amended Consent Statement are false and misleading because they fail to disclose that the Shareholder Rights Proposal is contrary to the provisions of the PBCL granting directors of a Pennsylvania corporation the sole discretion to determine the terms and conditions of rights plans; (iii) the Offer, as amended by the First Supplement, is unlawful because it constitutes a new tender offer and does not comply with federal securities laws requiring Parent to return all Shares tendered under its initial August 10, 1998 offer; (iv) by announcing its intention to commence the Second Offer upon expiration of the Offer, Parent was subject to a requirement under Rule 14d-2(b) to start the Second Offer within five days or abandon it, neither of which Parent has done; (v) because the Offer is not an amendment of the initial August 10, 1998 offer, but rather a new offer, Parent and Offeror were required to hold the Offer open for a minimum period of 20 business days and to return all Shares tendered in the initial August 10, 1998 offer; (vi) the Offer and the Second Offer are actually the same offer, and, as a result, the purchase of the Company's Shares under the Offer will be in violation of Rule 10b-13; and (vii) alternatively, Parent's offers pursuant to the initial August 10, 1998 offer, the First Supplement, the Second Supplement and the Second Offer are part of a single effort by Parent to acquire control of the Company, which should be treated as a single integrated offer, so that Rule 14d-10(a)(2) requiring that the Company's Shareholders receive the "highest consideration paid" would be applicable. In addition, the first amended complaint alleges that (i) the Nominee Election Proposals violate the PBCL because they would render it impossible for the Company's directors to discharge their fiduciary obligations to the Company; (ii) the Shareholders Rights Proposal violates the PBCL because it would divest the Company's Board of Directors of the authority under the PBCL to determine the terms and conditions of the Company's rights plans; and (iii) the Shares which the Parent and Offeror propose to buy are "control shares" within the meaning of the Control Share Acquisition Statute because Parent and Offeror have announced their intention to purchase all of the Company's Shares, and Parent and Offeror may not vote the Shares they propose to buy. The first amended complaint seeks: (i) declaratory relief declaring that the Shareholders Rights Proposal and the Nominee Election Proposals set forth in the Amended Consent Solicitation are contrary to Pennsylvania law; (ii) injunctive relief prohibiting Parent from (a) soliciting consents, (b) pursuing the Offer unless full compliance with federal securities laws, including full and accurate disclosure, is made, (c) soliciting consents unless full and accurate disclosure is made, and (d) voting any of the Company's Shares unless all requirements of the Control Share Acquisition Statute have been satisfied; (iii) compensatory damages for all injuries suffered by the Company; and (iv) costs and disbursements, including attorneys' fees. Parent and Offeror believe there is no merit to the Company's allegations and intend to vigorously defend against this lawsuit. ITEM 11. MATERIAL TO BE FILED AS EXHIBITS. (a)(56) Press Release issued by Parent on September 24, 1998.

NEWS RELEASE

Contact:   Mark Greenberg

                 ALLIEDSIGNAL WILL NOT PURCHASE 9% OF AMP
           IF PENNSYLVANIA REPEALS CONSENT SOLICITATION PROCESS

     MORRIS TOWNSHIP, New Jersey, September 24, 1998 - AlliedSignal Inc.
[NYSE: ALD] said today that if the Commonwealth of Pennsylvania enacts new
legislation which would prevent AlliedSignal from proceeding with its
consent solication, AlliedSignal will not proceed with the purchase of 9%
of the shares of AMP Incorporated [NYSE: AMP] under AlliedSignal's pending
$44.50 per share tender offer.

     If, on the other hand, Pennsylvania chooses not to amend the current
shareowner consent solicitation rights, AlliedSignal will proceed with the
purchase, which will put $900 million into AMP shareowners' pockets at a
price per share that is 55% more than the market price for AMP shares
before AlliedSignal announced its original $44.50 per share offer.

     AlliedSignal said that at the close of business on September 17, the
day before it amended its offer to reduce the number of AMP shares it would
purchase to 20 million, the number of AMP shares that had been tendered to
AlliedSignal and not withdrawn was 138,871,851.
