To: All Holders of Common Stock of AMP Incorporated. INTRODUCTION The following information amends and supplements the Offer to Purchase, dated August 10, 1998 (the 'Offer to Purchase'), of PMA Acquisition Corporation ('Offeror'), a Delaware corporation and a wholly owned subsidiary of AlliedSignal Inc., a Delaware corporation ('Parent'), pursuant to which Offeror is offering to purchase shares of common stock, without par value (the 'Shares'), of AMP Incorporated, a Pennsylvania corporation (the 'Company'), including the associated Common Stock Purchase Rights (the 'Rights'), issued pursuant to the Rights Agreement, dated as of October 25, 1989, as amended, between the Company and ChaseMellon Shareholder Services L.L.C., as Rights Agent (the 'Rights Agreement'). Unless the context otherwise requires, all references to Shares include the associated Rights, and all references to the Rights include the benefits that may inure to holders of the Rights pursuant to the Rights Agreement, including the right to receive any payment due upon redemption of the Rights. Offeror is now offering to purchase up to an aggregate of 40,000,000 Shares at $44.50 per Share, net to the seller in cash, without interest (the 'Offer Price'), upon the terms and subject to the conditions set forth in the Offer to Purchase, as amended by this First Supplement, and in the revised Letter of Transmittal (which, as amended from time to time, collectively constitute the 'Offer'). BECAUSE THE OFFER, AS AMENDED, CONTEMPLATES THE PURCHASE OF UP TO AN AGGREGATE OF 40,000,000 SHARES, OFFEROR BELIEVES THAT, BASED ON THE NUMBER OF SHARES OUTSTANDING AS REPORTED IN THE COMPANY 1998 SECOND QUARTER 10-Q, THE AMENDED BUSINESS COMBINATION CONDITION, THE AMENDED CONTROL SHARE CONDITION AND THE AMENDED RIGHTS CONDITION WILL BE SATISFIED FOR PURPOSES OF THE OFFER. THE OFFER, AS AMENDED, IS NO LONGER SUBJECT TO THE HSR CONDITION OR THE MINIMUM CONDITION. SEE SECTION 8. If Offeror becomes aware that the purchase of 40,000,000 Shares would constitute the purchase of 20% or more of the outstanding Shares or if any other event occurs that would result in Offeror being the beneficial owner of 20% or more of the outstanding Shares, Offeror intends to take any action it deems appropriate or advisable, including selling Shares (whether 'short' or otherwise) in the market or tendering into any competing tender offer, so that Offeror will not be an 'Acquiring Person' under the Rights Agreement and will not trigger the applicability of the Control Share Acquisition Statute, the Business Combination Statute, or Subchapters E or I of Chapter 25 of the Pennsylvania Business Corporation Law (the 'PBCL'). Concurrently with the filing of this First Supplement, Parent is filing with the Commission a revised preliminary Consent Statement (the 'Amended Consent Solicitation') pursuant to which it is soliciting the consent of holders of Shares to two sets of proposals (the 'Proposals'). The first proposal, the 'Shareholder Rights Proposal,' if approved by the Company's shareholders, would remove from the Company Board all powers with respect to the Rights Agreement and would vest those powers in three individuals, the Rights Agreement Managing Agents. The Rights Agreement Managing Agents will cause the Rights Agreement to be amended in a number of respects, including making it inapplicable (i) to any tender or exchange offer (including the Second Offer, as defined herein) if, as a result of that offer, the offeror and its affiliates would be the beneficial owners of a majority of the outstanding Shares and (ii) to any merger (including the Proposed Merger, as defined below) if the merger either does not require shareholder approval or is approved by the requisite vote of the Company's shareholders. The Rights Agreement Managing Agents will also cause the Rights Agreement to be amended to make the Rights redeemable and to make other changes to facilitate an acquisition of the Company by any person (including Parent). The second set of proposals, the 'Nominee Election Proposals,' if approved by the Company's shareholders, would result in the Nominees becoming a majority of the Company Board. The Nominees, if elected, intend, subject to their fiduciary duties as directors of the Company, to cause the Company to enter into an agreement providing for a merger or similar business combination (a 'Proposed Merger') with Parent providing for payment to the Company's shareholders of $44.50 per 1

Share in cash. This agreement would be subject to approval by the holders of at least 66 2/3% of the outstanding Shares, unless Parent shall have previously acquired 80% or more of the outstanding Shares pursuant to the Offer and the Second Offer or otherwise. The Nominees also intend to take whatever other actions are appropriate, subject to fulfillment of their fiduciary duties as directors of the Company, to facilitate the Second Offer, including approving the Second Offer and the Proposed Merger under the Business Combination Statute. In order to facilitate its acquisition of control of, and the entire equity interest in, the Company and to obtain a significant vote for purposes of the Amended Consent Solicitation, Parent and Offeror are hereby amending the Offer principally: (i) to reduce the aggregate number of Shares sought in the Offer to 40,000,000 Shares, approximately the maximum number of Shares (based on the number of outstanding Shares as reported in the Company 1998 Second Quarter 10-Q) that Offeror can acquire without becoming an 'Acquiring Person' under the Rights Agreement and without triggering the applicability of the Control Share Acquisition Statute, the Business Combination Statute or Subchapters E or I of Chapter 25 of the PBCL; (ii) to amend the Rights Condition, the Business Combination Condition and the Control Share Condition (each as defined in the Offer to Purchase) so that they are applicable to the Offer only and not to the consummation of the Proposed Merger; (iii) to eliminate the HSR Condition and the Minimum Condition; and (iv) to condition the Offer on there having been no material amendment made to the Rights Agreement after July 30, 1998, other than amendments publicly announced by the Company prior to September 10, 1998. See Introduction and Sections 12 and 15 of the Offer to Purchase and Section 8 of this First Supplement. THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES OR WRITTEN CONSENTS FROM THE COMPANY'S SHAREHOLDERS. ANY SOLICITATION OF PROXIES OR WRITTEN CONSENTS WHICH PARENT OR OFFEROR MIGHT MAKE WOULD BE MADE ONLY PURSUANT TO SEPARATE PROXY OR CONSENT SOLICITATION MATERIALS COMPLYING WITH THE REQUIREMENTS OF SECTION 14(a) OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED (THE 'EXCHANGE ACT'). Following Offeror's acceptance for payment of Shares in the Offer, Offeror intends promptly to commence another tender offer (the 'Second Offer') to purchase all outstanding Shares not owned by Offeror at a price of $44.50 per Share, net to the seller in cash, without interest, upon essentially the same terms and subject to the same conditions set forth in the Offer to Purchase in order to acquire control of, and the entire equity interest in, the Company. This First Supplement should be read in conjunction with the Offer to Purchase. Except as set forth in this First Supplement and the revised Letter of Transmittal, the terms and conditions previously set forth in the Offer to Purchase and the Letter of Transmittal mailed with the Offer to Purchase remain applicable in all respects to the Offer. Terms used but not defined in this First Supplement have the meanings set forth in the original Offer to Purchase. Based upon information contained in the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 1998 (the 'Company 1998 Second Quarter 10-Q'), as of July 27, 1998, 218,601,033 Shares were issued and outstanding. Accordingly, Parent believes that the 40,000,000 Shares for which the Offer is being made should constitute less than 20% of the outstanding Shares, which Offeror believes is less than the number of Shares that Offeror can purchase without becoming an 'Acquiring Person' under the Rights Agreement and without triggering the applicability of the Business Combination Statute, the Control Share Acquisition Statute or Subchapters E or I of Chapter 25 of the PBCL. See Sections 1, 12 and 15 of the Offer to Purchase and Section 8 of this First Supplement. THE OFFER TO PURCHASE, THIS FIRST SUPPLEMENT AND THE REVISED LETTER OF TRANSMITTAL CONTAIN IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH RESPECT TO THE OFFER. 1. TERMS OF THE OFFER; PRORATION; EXPIRATION DATE. The discussion set forth in Section 1 of the Offer to Purchase is hereby amended and supplemented as follows: Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any extension or amendment), Offeror will accept for payment and pay for up to an aggregate of 40,000,000 Shares that are validly tendered prior to the Expiration 2

Date (as defined herein) and not properly withdrawn in accordance with Section 4 of the Offer to Purchase. The term 'Expiration Date' means 12:00 Midnight, New York City time, on September 25, 1998 unless and until Offeror, in its sole discretion, shall have extended the period of time during which the Offer is open, in which event the term 'Expiration Date' will mean the latest time and date at which the Offer, as so extended by Offeror, will expire. THE OFFER IS CONDITIONED UPON SATISFACTION OF THE CONDITIONS SET FORTH IN SECTION 8 OF THIS FIRST SUPPLEMENT. OFFEROR RESERVES THE RIGHT (SUBJECT TO THE APPLICABLE RULES AND REGULATIONS OF THE COMMISSION) TO AMEND OR WAIVE ANY TERMS AND CONDITIONS OF THE OFFER. If more than 40,000,000 Shares are validly tendered prior to the Expiration Date and not properly withdrawn, Offeror will, upon the terms and subject to the conditions of the Offer, accept for payment and pay for only 40,000,000 Shares, on a pro rata basis, with adjustments to avoid purchases of fractional Shares, based upon the number of Shares validly tendered prior to the Expiration Date and not properly withdrawn. Because of the difficulty of determining precisely the number of Shares validly tendered and not withdrawn, if proration is required, Offeror would not expect to be able to announce the final results of proration or pay for Shares until at least three days after the Expiration Date. Preliminary results of proration will be announced by press release as promptly as practicable after the Expiration Date. Holders of Shares may obtain such preliminary information from the Information Agent and also may be able to obtain such preliminary information from their brokers. 2. PROCEDURES FOR TENDERING SHARES. The discussion set forth in Section 3 of the Offer to Purchase is hereby amended and supplemented as follows: TO BE VALID, A TENDER OF SHARES MUST BE ACCOMPANIED BY CERTIFICATES REPRESENTING SHARES OR THE BOOK-ENTRY TRANSFER PROCEDURES MUST BE COMPLIED WITH ON A TIMELY BASIS. SEE SECTION 3 OF THE OFFER TO PURCHASE. SHARES MAY NOT BE TENDERED PURSUANT TO GUARANTEED DELIVERY PROCEDURES AFTER THE DATE OF THIS FIRST SUPPLEMENT. The revised Letter of Transmittal distributed with this First Supplement may be used to tender Shares. Tendering shareholders also may continue to use the Letter of Transmittal previously delivered with the Offer to Purchase to tender Shares. HOWEVER, THE PROVISIONS IN THE PREVIOUSLY DISTRIBUTED LETTER OF TRANSMITTAL RELATING TO GUARANTEED DELIVERY WILL NO LONGER BE APPLICABLE TO THE OFFER. By tendering Shares pursuant to the revised Letter of Transmittal or the Letter of Transmittal previously delivered, tendering shareholders will be deemed to represent and warrant to Parent and Offeror that the tender of Shares complies with Rule 14e-4 under the Exchange Act. SHAREHOLDERS WHO HAVE PREVIOUSLY VALIDLY TENDERED SHARES PURSUANT TO THE INITIAL OFFER AND WHO HAVE NOT WITHDRAWN THOSE SHARES NEED NOT TAKE ANY FURTHER ACTION IN ORDER TO TENDER SHARES PURSUANT TO THE OFFER, AS AMENDED. SHAREHOLDERS WHO HAVE TENDERED SHARES ON OR PRIOR TO SEPTEMBER 11, 1998 PURSUANT TO GUARANTEED DELIVERY PROCEDURES SHOULD COMPLY WITH THE REQUIRED PROCEDURES. SEE SECTION 3 OF THE OFFER TO PURCHASE. By executing the Letter of Transmittal, a tendering shareholder irrevocably appoints designees of Offeror as the shareholder's attorneys-in-fact and proxies, each with full power of substitution, in the manner set forth in the appropriate Letter of Transmittal, to the full extent of the shareholder's right with respect to the Shares (or, if applicable, Rights) tendered by that shareholder and accepted for payment by Offeror (and any and all other Shares or other securities or rights issued or issuable in respect of these Shares on or after August 10, 1998). All powers of attorney and proxies will be considered irrevocable and coupled with an interest in the tendered Shares. This appointment is effective upon the acceptance for payment of Shares by Offeror in accordance with the terms of the Offer. Upon acceptance for payment, all prior proxies, other than any consents in favor of proposals set forth in the Consent Solicitation, given by the shareholder with respect to these Shares or other securities or rights will, without further action, be revoked and no subsequent proxies may be given or written consents executed by the shareholder (and, if given or executed, will not be deemed effective) with respect to these Shares. The designees of Offeror will, with respect to the Shares and other 3

securities or rights, be empowered to exercise all voting and other rights of the shareholder as they, in their sole judgment, deem proper in respect of any annual or special meeting of the Company's shareholders, or any adjournment or postponement thereof, or by written consent in lieu of any meeting or otherwise. Offeror reserves the right to require that, in order for Shares to be deemed validly tendered, immediately upon Offeror's payment for the Shares, Offeror or its designee must be able to exercise full voting and other rights with respect to the Shares and the other securities or rights issued or issuable in respect of the Shares, including the voting of Common Stock at any shareholders meeting (whether annual or special or whether or not adjourned) or written consents in lieu of any meeting or otherwise. OFFEROR INTENDS TO VOTE ALL SHARES ACQUIRED IN THE OFFER IN FAVOR OF THE PROPOSALS. 3. PRICE RANGE OF COMMON STOCK; DIVIDENDS. The discussion set forth in Section 6 of the Offer to Purchase is hereby amended and supplemented as follows: On September 11, 1998, the last full trading day before AlliedSignal's public announcement of its intention to amend the Offer, the last reported closing price of the Shares on the NYSE was $39.00. SHAREHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE SHARES. 4. SOURCE AND AMOUNT OF FUNDS. The discussion set forth in Section 10 of the Offer to Purchase is hereby amended and supplemented as follows: Offeror estimates that the total amount of funds now required to acquire Shares pursuant to the Offer and the Second Offer and to pay all related costs and expenses, will be approximately $10.1 billion, of which approximately $2.0 billion will be required to consummate the Offer and to pay related costs and expenses. Parent anticipates borrowing up to approximately $2.0 billion by issuing commercial paper and/or engaging in either short, medium and possibly long-term borrowings, or a combination thereof, in the bank, private and public debt market to finance the acquisition of the Shares pursuant to the Offer and to pay the related costs and expenses. 5. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY. The discussion set forth in Section 11 of the Offer to Purchase is hereby amended and supplemented as follows: On August 12, 1998, AlliedSignal filed preliminary materials for its consent solicitation, in which it stated that it was seeking shareholders' consent to the Nominee Proposals. Prior to the Company's amendment of the Rights Agreement described below, the Rights Agreement had provided that, under certain circumstances, the decision to redeem the Rights required the concurrence of a majority of the members of the Company Board who were members of the Company Board prior to October 25, 1989 (the 'Continuing Directors') or their nominees (the 'Dead Hand Provision'). Parent and Offeror believed that the Dead Hand Provision was unenforceable. Accordingly, on August 4, 1998, Parent filed a complaint against the Company in the United States District Court for the Eastern District of Pennsylvania in which it sought relief declaring the Dead Hand Provision invalid. Parent believed that the Rights Agreement, as in effect at the time the Offer commenced, would have permitted Parent to consummate a merger with the Company without triggering the dilutive effect of the Rights, so long as Parent did not acquire 20% or more of the Shares before the merger. Parent was also of the view that, if the Nominees were elected to and constituted a majority of the Company Board, the Continuing Directors could have been persuaded to redeem the Rights, in furtherance of their fiduciary duties to the Company, although there were no assurances that this would have been the case. On August 21, 1998, the Company filed with the Commission a Solicitation/Recommendation Statement on Schedule 14D-9, which reflected the conclusion of the Company Board that Offeror's initial offer for any and all Shares was not in the best interests of the Company and its relevant constituencies and recommended to Company shareholders that they reject that offer. In response to the Offeror's initial offer for any and all Shares and to Parent's stated intention to seek shareholder consent to the election of the Nominees, the Company Board approved, at a meeting 4

held on August 20, 1998, Amendment No. 3 to the Rights Agreement, which amended the Rights Agreement to provide that: (i) unless the Rights are redeemed prior thereto, a merger or other business combination transaction will be an event triggering a Transaction Exercise Right, irrespective of whether other events have previously occurred to cause the Rights Certificates to have been distributed, (ii) the Rights shall become nonredeemable upon a change in the Board occurring at any time following receipt of an unsolicited acquisition proposal such that the disinterested directors (as such term is defined under Pennsylvania law) in office prior to the first such unsolicited acquisition proposal, together with their successors as may be approved by the Board of Directors prior to their election, no longer constitute a majority of the Board of Directors, (iii) the Qualifying Offer exception shall be applicable unless and until the Rights become nonredeemable under clause (ii) above, and (iv) the Rights Agreement generally may not be amended when the Rights are not redeemable. The amendment to the Rights Agreement referred to above (the 'Nonredemption Provision'), which effectively replaced the Dead Hand Provision, makes the Rights non-redeemable by any directors, even 'disinterested' directors, if a majority of the Company Board are persons other than the present directors of the Company or their designees. This amendment also eliminated Parent's ability to consummate a merger without prior redemption of the Rights. The Nonredemption Provision would remain in effect until the expiration of the Rights Agreement on November 6, 1999 and, if the Nominees are elected and constitute a majority of the Company Board, would preclude a business combination prior to November 6, 1999 by the Company with any person, including Parent, no matter what the price offered or terms specified. At the August 20, 1998 meeting, the Company Board also adopted a resolution providing that, for a period of six months after the expiration of the Rights Agreement, the Company will neither adopt nor have in place a shareholder rights plan. Parent and Offeror believe that the Nonredemption Provision is invalid and unenforceable because it unlawfully interferes with the rights of shareholders to elect directors and unlawfully deprives directors of their ability to manage the business and affairs of the Company. Parent is amending its complaint to seek a declaration that the Nonredemption Provision is invalid and unenforceable. See Section 9 of this First Supplement. On September 4, 1998, Parent entered into an agreement with the Company (the 'Notice Agreement'), pursuant to which Parent agreed to give at least six calendar days' notice to the Company prior to making any amendments, changes or additions (including the addition of new proposals) to the Proposals set forth in the Consent Solicitation, and pursuant to which the Company agreed to give at least six calendar days' notice to Parent prior to (i) the issuance or sale by the Company, other than in an aggregate amount not exceeding five percent of the Company's outstanding Common Stock, of any Company Common Stock; (ii) the amendment by the Company of the Company By-laws; and (iii) the amendment by the Company of the Rights Agreement. Pursuant to the agreement, Parent also agreed not to contest the Consent Solicitation record date of October 15, 1998. Concurrently with the filing of this First Supplement, Parent is filing the Amended Consent Solicitation with the Commission. See Section 6 of this First Supplement. 6. PURPOSES OF THE OFFER AND THE PROPOSED MERGER; PLANS FOR THE COMPANY; CERTAIN CONSIDERATIONS. The discussion set forth in Section 12 of the Offer to Purchase is hereby amended and supplemented as follows: The purposes of the Offer are for Parent, through Offeror, to acquire a significant equity interest in the Company as the first step toward a business combination of Parent and the Company and to obtain a significant vote for purposes of the Amended Consent Solicitation. Following Offeror's acceptance for payment of Shares in the Offer, Purchaser intends to commence the Second Offer to acquire control of, and the entire equity interest in, the Company. The Second Offer will be subject to essentially the same terms and conditions set forth in the Offer to Purchase, including the Minimum Condition, the Business Combination Condition, the Control Share Condition and the Rights Condition (each as defined in the Offer to Purchase). 5

In furtherance of its efforts to acquire control of, and the entire equity interest in, the Company, Parent intends to solicit shareholder consents to the Proposals. The first Proposal, the 'Shareholder Rights Proposal,' if approved by the Company's shareholders, would remove from the Company Board all powers with respect to the Rights Agreement and would vest those powers in three individuals, the Rights Agreement Managing Agents. The Rights Agreement Managing Agents will cause the Rights Agreement to be amended in a number of respects, including making it inapplicable (i) to any tender or exchange offer (including the Second Offer) if, as a result of the offer, the offeror and its affiliates would be the beneficial owner of a majority of the outstanding Shares and (ii) to any merger (including the Proposed Merger) if the merger either does not require shareholder approval or is approved by the requisite vote of the Company's shareholders. The Rights Agreement Managing Agents will also cause the Rights Agreement to be amended to make the Rights redeemable and to make other changes to facilitate an acquisition of the Company by any person (including Parent). The second set of proposals, the 'Nominee Election Proposals,' if approved by the Company's shareholders, would result in the Nominees becoming a majority of the Company Board. The Nominees, if elected, intend, subject to their fiduciary duties, to cause the Company to enter into a Proposed Merger with Parent providing for payment to the Company's shareholders of $44.50 per Share in cash. This agreement would be subject to approval by the holders of 66 2/3% of the outstanding shares of Company Common Stock, unless Parent shall have previously acquired 80% or more of the outstanding shares of Company Common Stock pursuant to the Offer and the Second Offer or otherwise. The Nominees also intend to take whatever other actions are appropriate, subject to fulfillment of their fiduciary duties as directors of the Company, to facilitate the Second Offer, including approving the Second Offer and the Proposed Merger under the Business Combination Statute. The Company Board has fixed October 15, 1998, as the record date for the Consent Solicitation for the Nominee Election Proposals. Offeror has asked the Company to confirm that October 15, 1998 will also be the record date for the Shareholder Rights Proposal. THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES OR WRITTEN CONSENTS FROM THE COMPANY'S SHAREHOLDERS. ANY SOLICITATION OF PROXIES OR WRITTEN CONSENTS WHICH PARENT OR OFFEROR UNDERTAKES WOULD BE MADE ONLY PURSUANT TO SEPARATE PROXY OR CONSENT SOLICITATION MATERIALS IN COMPLIANCE WITH THE REQUIREMENTS OF SECTION 14(a) OF THE EXCHANGE ACT. 7. DIVIDENDS AND DISTRIBUTIONS. The second paragraph of Section 13 of the Offer to Purchase is hereby amended in its entirety to read as follows: If, on or after the date of the Offer to Purchase, the Company should declare or pay any dividend on the Shares, other than the regular quarterly dividend of not more than $0.27 per Share, or make any distribution (including, without limitation, the issuance of additional Shares pursuant to a stock dividend or stock split, the issuance of other securities or the issuance of rights for the purchase of any securities) with respect to the Shares that is payable or distributable to shareholders of record on a date prior to the transfer to the name of Offeror or its nominee or transferee on the Company's share register of the Shares purchased pursuant to the Offer, then, subject to the provisions of Section 14 of the Offer to Purchase, as amended by this First Supplement, (i) in the case of any cash dividends or cash contributions, at Offeror's option, either (x) the Offer Price payable by Offeror pursuant to the Offer will be reduced by the amount of the cash dividend or cash distribution or (y) the amount of the cash dividend or cash distribution will be received and held by the tendering shareholder for the account of Offeror and will be required to be promptly remitted and transferred by each tendering shareholder to the Depositary for the account of Offeror and (ii) in the case of any non-cash dividend, distribution or right to be received by the tendering shareholders, that dividend, distribution or right will be received and held by the tendering shareholders for the account of Offeror and will be required to be promptly remitted and transferred by each tendering shareholder to the Depositary for the account of Offeror, accompanied by appropriate documentation of transfer. Pending this remittance and subject to applicable law, Offeror will be entitled to all rights and privileges as owner of any cash or non-cash dividend, distribution or right and may withhold the entire purchase price or deduct from the purchase price the amount of value thereof, as determined by Offeror in its sole discretion. 6

8. CONDITIONS OF THE OFFER. The discussion set forth in Section 14 of the Offer to Purchase is hereby amended in its entirety to read as follows: Notwithstanding any other terms of the Offer, and in addition to (and not in limitation of) Offeror's rights to extend and amend the Offer at any time in its sole discretion, Offeror will not be required to accept for payment or, subject to any applicable rules and regulations of the Commission, including Rule 14e-1(c) under the Exchange Act (relating to Offeror's obligation to pay for or return tendered Shares promptly after termination or withdrawal of the Offer), pay for, and may delay the acceptance for payment of or, subject to the restriction above, the payment for, any tendered Shares, and may terminate the Offer as to any Shares not then paid for, if Offeror, in its sole discretion, determines (1) at or prior to the expiration of the Offer (i) the Rights have not been redeemed by the Company Board or Offeror is not satisfied, in its sole discretion, that the Rights have been invalidated or are otherwise inapplicable to the Offer (the 'Amended Rights Condition');

(g) the Company and Parent or Offeror shall have reached an agreement or understanding that the Offer be terminated or amended or Parent or Offeror (or one of their respective affiliates) 9

shall have entered into a definitive agreement or an agreement in principle to acquire the Company by merger or similar business combination; (h) Parent or Offeror shall become aware (i) that any material contractual right of the Company or any of its subsidiaries or affiliates shall be impaired or otherwise adversely affected or that any material amount of indebtedness of the Company of any of its subsidiaries shall become accelerated or otherwise become due prior to its stated due date, in either case with or without notice or the lapse of time or both, as a result of the transactions contemplated by the Offer, (ii) of any covenant, term or condition in any of the Company's or any of its subsidiaries' instruments or agreements that are or may be materially adverse to the value of the Shares in the hands of Offeror or any other affiliate of Parent (including, but not limited to, any event of default that may ensue as a result of the consummation of the Offer or any other business combination or the acquisition of control of the Company) or (iii) other than amendments publicly announced by the Company prior to September 10, 1998, the Rights Agreement shall have been amended in any material respect; or (i) Parent or Offeror shall not have obtained any waiver, consent, extension, approval, action or non-action from any governmental authority or agency which in its judgment is necessary to consummate the Offer, which, in the sole judgment of Parent or Offeror in any case, and regardless of the circumstances (including any action or inaction by Parent or Offeror or any of their affiliates) giving rise to any condition, makes it inadvisable to proceed with the Offer and/or with acceptance for payment or payment for Shares. The foregoing conditions are for the sole benefit of Parent and Offeror and may be asserted by Parent and Offeror in their sole discretion regardless of the circumstances giving rise to any conditions or may be waived by Parent or Offeror in their sole discretion in whole or in part at any time and from time to time. The failure by Parent or Offeror at any time to exercise any of the foregoing rights will not be deemed a waiver of any right and each right shall be deemed an ongoing right which may be asserted at any time and from time to time. Any determination by Parent or Offeror concerning any condition or event described in this Section 14 shall be final and binding upon all parties. If the Offeror makes a material change in the terms of the Offer or the information concerning the Offer or waives a material condition of the Offer without relying on the exercise of its reasonable judgment or some other objective criteria, the Offeror will disseminate additional tender offer materials and extend the Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 of the Exchange Act. BECAUSE THE OFFER, AS AMENDED, CONTEMPLATES THE PURCHASE OF UP TO AN AGGREGATE OF 40,000,000 SHARES, OFFEROR BELIEVES THAT, BASED ON THE NUMBER OF SHARES OUTSTANDING AS REPORTED IN THE COMPANY 1998 SECOND QUARTER 10-Q, THE AMENDED BUSINESS COMBINATION CONDITION, THE AMENDED CONTROL SHARE CONDITION AND THE AMENDED RIGHTS CONDITION WILL BE SATISFIED FOR PURPOSES OF THE OFFER. 9. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS; CERTAIN LITIGATION. The discussion set forth in Section 15 of the Offer to Purchase is hereby amended and supplemented as follows: CERTAIN LITIGATION. On August 4, 1998, Parent filed a complaint against the Company in the Eastern District of Pennsylvania, styled AlliedSignal Inc. v. AMP Incorporated, C.A. No. 98-CV-4058 (JTG) (the 'AlliedSignal Complaint'), which is now being amended as set forth below. On August 21, 1998, the Company filed a complaint against Parent and Offeror in the Eastern District of Pennsylvania styled AMP Incorporated v. AlliedSignal Corporation and PMA Acquisition Corporation, C.A. No. 98-CV-4405 (the 'Company Action'). The complaint seeks: (i) declaratory relief declaring that the proposals set forth in Parent's consent solicitation are contrary to Pennsylvania law because Parent's Nominees 'could not fulfill their fiduciary duties both to [Parent] and its shareholders and to [the Company]'; and (ii) injunctive relief prohibiting Parent from (a) soliciting consents, (b) pursuing the initial Offer, and (c) soliciting any consents unless full and accurate disclosure is made regarding the nature of Parent's proposals. Parent and Offeror believe there is no merit to the Company's allegations and intend to vigorously defend themselves against this lawsuit. On August 24, 1998, the Company filed an Answer to the AlliedSignal Complaint denying Parent's contentions and asserting as affirmative defenses that (i) the AlliedSignal Complaint fails to state a 10

claim for which relief may be granted, (ii) Parent does not have standing to bring the claims and (iii) the claims are moot because the Rights Agreement has been amended and the 'Dead Hand Provision' has been removed. On September 11, 1998, in the Company Action, the Company filed a motion for Partial Summary Judgment in the Nature of a Declaratory Judgment seeking a declaration that Parent's consent solicitation plan is 'unlawful and in violation of Pennsylvania law and public policy' on the ground that allegedly Parent's 'plan to pack AMP's Board [with Parent's nominees] will created a pervasive and irreconcilable conflict of interest -- one that is abhorrent to the law and public policy of the Commonwealth.' The Company requested that the hearing on that motion be scheduled to be heard on September 28, 1998. Parent is filing a motion to amend the AlliedSignal Complaint (the 'Amended Complaint'). The Amended Complaint will seek: (i) declaratory and injunctive relief declaring the Nonredemption Provision invalid under Pennsylvania law; or to the extent that the Nonredemption Provision and other anti-takeover devices that preclude tender offers and consent solicitations are permitted under Pennsylvania law, declaring this law as so applied unconstitutional under the Supremacy and Commerce Clauses of the United States Constitution and (ii) declaratory and injunctive relief prohibiting any effort by the Company Board to manipulate or otherwise subvert the process of corporate democracy by (a) amending the Company By-laws, (b) taking advantage of the delay of the Record Date until October 15, 1998, to manipulate the corporate machinery or thwart or interfere with the Offer or the Amended Consent Solicitation, or (c) taking any other action to frustrate the Offer or the Amended Consent Solicitation. Parent is also filing a motion for (1) partial summary judgment on its claim for a declaratory judgment in the Amended Complaint that the Nonredemption Provision is ultra vires and invalid, or, in the alternative, a preliminary injunction restraining enforcement of the Nonredemption Provision; and (2) a preliminary injunction prohibiting the Company Board from amending the Company By-laws or Rights Agreement or taking any other action that would, as a practical matter, make the shareholder vote on the Amended Consent Solicitation meaningless. Parent will request that its motion be heard on the same date on which the Court schedules the hearing on the Company's motion in the Company Action. 10. MISCELLANEOUS. Parent and Offeror have filed with the Commission amendments to the Schedule 14D-1, together with exhibits, pursuant to Rule 14d-3 of the General Rules and Regulations under the Exchange Act, furnishing certain additional information with respect to the Offer. The Schedule 14D-1, and any amendments thereto, may be inspected at, and copies may be obtained from, the same places and in the same manner as set forth in Section 9 of the Offer to Purchase (except that they may not be available at the regional offices of the Commission).

Ladies and Gentlemen: The undersigned hereby tenders to PMA Acquisition Corporation, a Delaware corporation (the 'Offeror'), a wholly owned subsidiary of AlliedSignal Inc., a Delaware corporation (the 'Parent'), the above-described shares of Common Stock, without par value (the 'Shares'), of AMP Incorporated, a Pennsylvania corporation (the 'Company'), together with an equal number of any associated Common Stock Purchase Rights (the 'Rights') issued pursuant to the Rights Agreement, as amended (the 'Rights Agreement'), between the Company and ChaseMellon Shareholder Services L.L.C., as Rights Agent, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated August 10, 1998 (the 'Offer to Purchase'), as amended by the First Supplement to the Offer of Purchase, dated September 14, 1998 (the 'First Supplement') and in this Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the 'Offer'), receipt of which is hereby acknowledged. Upon the terms of the Offer, subject to, and effective upon, acceptance for payment of, and payment for, the Shares and, if applicable, Rights tendered herewith in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Offeror all right, title and interest in and to all the Shares and, if applicable, Rights that are being tendered hereby (and any and all other Shares, Rights or other securities or rights issued or issuable in respect thereof on or after August 10, 1998), and irrevocably constitutes and appoints The Bank of New York (the 'Depositary'), the true and lawful agent and attorney-in-fact of the undersigned, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to the full extent of the undersigned's rights with respect to such Shares and, if applicable, Rights (and any such other Shares, Rights or securities or rights), to (a) deliver certificates for such Shares and Rights (and any such other Shares, Rights or securities or rights) or transfer ownership of such Shares and Rights (and any such other Shares, Rights or securities or rights) on the account books maintained by a Book-Entry Transfer Facility together, in any such case, with all accompanying evidences of transfer and authenticity to, or upon the order of, the Offeror, (b) in the case of participants in the Direct Registration System ('DRS'), to place a stop against the Shares held under DRS and, following expiration of the Offer, to instruct the Transfer Agent to transfer such Shares, (c) present such Shares and Rights (and any such other Shares, Rights or securities or rights) for transfer on the Company's books and (d) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares and Rights (and any such other Shares, Rights or securities or rights), all in accordance with the terms of the Offer. The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the tendered Shares and, if applicable, Rights (and any and all other Shares, Rights or other securities or rights issued or issuable in respect of such Shares or Rights on or after August 10, 1998) and, when the same are accepted for payment by the Offeror, the Offeror will acquire good title thereto, free and clear of all liens, restrictions, claims and encumbrances, and the same will not be subject to any adverse claim. The undersigned will, upon request, execute any additional documents deemed by the Depositary or the Offeror to be necessary or desirable to complete the sale, assignment and transfer of the tendered Shares and Rights (and any and all other Shares, Rights or other securities or rights issued or issuable in respect thereof on or after August 10, 1998). THE UNDERSIGNED UNDERSTANDS THAT, UNLESS THE AMENDED RIGHTS CONDITION (AS DEFINED IN THE FIRST SUPPLEMENT) IS SATISFIED, SHAREHOLDERS WILL BE REQUIRED TO TENDER ONE RIGHT FOR EACH SHARE TENDERED IN ORDER TO EFFECT A VALID TENDER OF SHARES IN ACCORDANCE WITH THE PROCEDURES SET FORTH IN SECTION 3 OF THE OFFER TO PURCHASE, AS AMENDED. If the Distribution Date occurs and separate certificates representing the Rights are distributed to holders of Shares prior to the time Shares are tendered herewith, certificates representing a number of Rights equal to the number of Shares being tendered herewith must be delivered to the Depositary or, if available, a Book-Entry Confirmation must be received by the Depositary with respect thereto, in order for such Shares tendered herewith to be validly tendered. If the Distribution Date occurs and separate certificates representing the Rights are not distributed prior to the time Shares are tendered herewith, a tender of Shares constitutes an agreement by the tendering shareholder to deliver certificates representing a 5

number of Rights equal to the number of Shares tendered pursuant to the Offer to the Depositary within a period ending three New York Stock Exchange trading days after the date certificates representing the Rights are distributed, or a Book-Entry Confirmation with respect to Rights (the 'Rights Delivery Period'). However, after expiration of the Rights Delivery Period, the Offeror may elect to reject as invalid a tender of Shares with respect to which certificates for, or a Book-Entry Confirmation with respect to, an equal number of Rights has not been received by the Depositary. Nevertheless, Offeror will be entitled to accept for payment Shares tendered by the undersigned prior to the receipt of the certificates for the Rights required to be tendered with such Shares, or a Book-Entry Confirmation with respect to such Rights, and either (a), subject to complying with the applicable rules and regulations of the Securities and Exchange Commission, withhold payment for such Shares pending receipt of the certificates for, or a Book-Entry Confirmation with respect to, such Rights or (b) make payment for Shares accepted for payment pending receipt of the certificates for, or a Book-Entry Confirmation with respect to, such Rights in reliance upon the agreement of a tendering shareholder to deliver Rights. Any determination by the Offeror to make payment for Shares in reliance upon such agreement or, after the expiration of the Rights Delivery Period, to reject a tender as invalid will be made in the sole and absolute discretion of the Offeror.

INSTRUCTIONS FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER 1. GUARANTEE OF SIGNATURES. No signature guarantee is required on this Letter of Transmittal (a) if this Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this Section, includes any participant in any of the Book-Entry Transfer Facilities' systems whose name appears on a security position listing as the owner of the Shares) of Shares and Rights tendered herewith, unless such registered holder(s) has completed either the box entitled 'Special Payment Instructions' or the box entitled 'Special Delivery Instructions' on the Letter of Transmittal or (b) if such Shares and Rights are tendered for the account of a financial institution (including most commercial banks, savings and loan associations and brokerage houses) that is a participant in the Security Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange Medallion Program (an 'Eligible Institution'). In all other cases, all signatures on this Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 5. 2. DELIVERY OF LETTER OF TRANSMITTAL AND SHARES. This Letter of Transmittal is to be completed by shareholders either if certificates are to be forwarded herewith or, unless an Agent's Message is utilized, if delivery of Shares and, if applicable, Rights is to be made pursuant to the procedures for book-entry transfer set forth in Section 3 of the Offer to Purchase or if delivery of Shares is to be made pursuant to DRS. For a shareholder validly to tender Shares and Rights pursuant to the Offer, a properly completed and duly executed Letter of Transmittal (or facsimile thereof), together with any required signature guarantees, or, in the case of a book-entry transfer, an Agent's Message, and any other required documents, must be received by the Depositary at one of its addresses set forth herein prior to the Expiration Date and either certificates for tendered Shares and Rights must be received by the Depositary at one of such addresses or Shares and Rights must be delivered pursuant to the procedures for book-entry transfer set forth herein (and a Book-Entry Confirmation received by the Depositary), in each case prior to the Expiration Date. UNLESS THE AMENDED RIGHTS CONDITION IS SATISFIED, SHAREHOLDERS WILL BE REQUIRED TO TENDER ONE RIGHT FOR EACH SHARE TENDERED IN ORDER TO EFFECT A VALID TENDER OF SHARES. Unless the Distribution Date occurs, a tender of Shares will also constitute a tender of the associated Rights. If the Distribution Date occurs and separate certificates representing the Rights are distributed prior to the time Shares are tendered herewith, certificates representing a number of Rights equal to the number of Shares being tendered herewith must be delivered to the Depositary or, if available, a Book-Entry Confirmation must be received by the Depositary with respect thereto, in order for such Shares tendered herewith to be validly tendered. If the Distribution Date occurs and separate certificates representing the Rights are not distributed prior to the time Shares are tendered herewith, a tender of Shares constitutes an agreement by the tendering shareholder to deliver certificates representing a number of Rights equal to the number of Shares tendered pursuant to the Offer to the Depositary within a period ending three New York Stock Exchange trading days after the date certificates representing the Rights are distributed, or a Book-Entry Confirmation with respect to Rights. SHARES MAY NOT BE TENDERED PURSUANT TO GUARANTEED DELIVERY PROCEDURES AFTER SEPTEMBER 14, 1998. The term 'Agent's Message' means a message, transmitted by a Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a Book-Entry Confirmation, which states that such Book-Entry Transfer Facility has received an express acknowledgment from the participant in such Book-Entry Transfer Facility tendering the Shares that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that the Purchaser may enforce such agreement against the participant. The signatures on this Letter of Transmittal cover the Shares and the Rights tendered hereby whether or not such Rights are delivered simultaneously with such Shares. THE METHOD OF DELIVERY OF SHARES, RIGHTS, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT THE ELECTION AND RISK OF THE TENDERING SHAREHOLDER. SHARES WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY 10

INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY. No alternative, conditional or contingent tenders will be accepted and no fractional Shares or Rights will be purchased. All tendering shareholders, by execution of this Letter of Transmittal (or facsimile hereof), waive any right to receive any notice of the acceptance of their Shares or Rights for payment. 3. INADEQUATE SPACE. If the space provided herein is inadequate, the certificate numbers and/or the number of Shares or Rights should be listed on a separate schedule attached hereto. 4. PARTIAL TENDERS (NOT APPLICABLE TO STOCKHOLDERS WHO TENDER BY BOOK-ENTRY TRANSFER). If fewer than all the Shares or Rights evidenced by any certificate submitted are to be tendered, fill in the number of Shares or Rights that are to be tendered in the box entitled 'Number of Shares Tendered' or 'Number of Rights Tendered', as appropriate. In any such case, new certificate(s) for the remainder of the Shares or Rights that were evidenced by the old certificate(s) will be sent to the registered holder, unless otherwise provided in the appropriate box on this Letter of Transmittal, as soon as practicable after the acceptance for payment of, and payment for, the Shares and Rights tendered herewith. All Shares and Rights represented by certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated. 5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS. If this Letter of Transmittal is signed by the registered holder of the Shares and Rights tendered hereby, the signature must correspond with the name as written on the face of the certificate(s) without any change whatsoever. If any of the Shares or Rights tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal. If any tendered Shares or Rights are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of certificates. If this Letter of Transmittal or any certificates or stock powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and proper evidence satisfactory to the Offeror of their authority so to act must be submitted. When this Letter of Transmittal is signed by the registered owner(s) of the Shares and Rights listed and transmitted hereby, no endorsements of certificates or separate stock powers are required unless payment or certificates for Shares or Rights not tendered or accepted for payment are to be issued to a person other than the registered owner(s). Signatures on such certificates or stock powers must be guaranteed by an Eligible Institution. If this Letter of Transmittal is signed by a person other than the registered owner(s) of the certificates listed, the certificates must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name or names of the registered owner or owners appear on the certificates. Signatures on such certificates or stock powers must be guaranteed by an Eligible Institution. 6. STOCK TRANSFER TAXES. The Offeror will pay any stock transfer taxes with respect to the transfer and sale of Shares or Rights to it or its order pursuant to the Offer. If, however, payment of the purchase price is to be made to, or if certificates for Shares or Rights not tendered or accepted for payment are to be registered in the name of, any person(s) other than the registered holder(s), or if tendered certificates are registered in the name(s) of any person(s) other than the person(s) signing this Letter of Transmittal, the amount of any stock transfer taxes (whether imposed on the registered holder(s) or such person(s)) payable on account of the transfer to such person(s) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes or exemption therefrom is submitted. 11

EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF TRANSMITTAL. 7. SPECIAL PAYMENT AND DELIVERY INSTRUCTION. If a check is to be issued in the name of, and/or certificates for Shares or Rights not accepted for payment are to be returned to, a person other than the signer of this Letter of Transmittal or if a check is to be sent and/or such certificates are to be returned to a person other than the signer of this Letter of Transmittal or to an address other than that shown above, the appropriate boxes on this Letter of Transmittal should be completed. 8. WAIVER OF CONDITIONS. The Offeror reserves the absolute right in its sole discretion to waive any of the specified conditions of the Offer, in whole or in part, in the case of any Shares or Rights tendered. 9. 31% BACKUP WITHHOLDING. In order to avoid 'backup withholding' of federal income tax on payments of cash pursuant to the Offer, a shareholder surrendering Shares in the Offer must, unless an exemption applies, provide the Depositary with such shareholder's correct taxpayer identification number ('TIN') on Substitute Form W-9 in this Letter of Transmittal and certify under penalty of perjury that such TIN is correct and that such shareholder is not subject to backup withholding. If a shareholder does not provide such shareholder's correct TIN or fails to provide the certifications described above, the Internal Revenue Service (the 'IRS') may impose a $50 penalty on such shareholder and payment of cash to such shareholder pursuant to the Offer may be subject to backup withholding of 31%. Backup withholding is not an additional income tax. Rather, the amount of the backup withholding can be credited against the Federal income tax liability of the person subject to the backup withholding, provided that the required information is given to the IRS. If backup withholding results in an overpayment of tax, a refund can be obtained by the shareholder upon filing an income tax return. The shareholder is required to give the Depositary the TIN (i.e., social security number or employer identification number) of the record owner of the Shares. If the Shares are held in more than one name or are not in the name of the actual owner, consult the enclosed 'Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9' for additional guidance on which number to report. The box in Part III of the Substitute Form W-9 may be checked if the tendering shareholder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If the box in Part III is checked, the shareholder or other payee must also complete the Certificate of Awaiting Taxpayer Identification Number below in order to avoid backup withholding. Notwithstanding that the box in Part III is checked and the Certificate of Awaiting Taxpayer Identification Number is completed, the Depositary will withhold 31% on all payments made prior to the time a properly certified TIN is provided to the Depositary. However, such amounts will be refunded to such shareholder if a TIN is provided to the Depositary within 60 days. Certain shareholders (including, among others, all corporations and certain foreign individuals and entities) are not subject to backup withholding. Noncorporate foreign shareholders should complete and sign the main signature form and a Form W-8, Certificate of Foreign Status, a copy of which may be obtained from the Depositary, in order to avoid backup withholding. See the enclosed 'Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9' for more instructions. 10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for assistance or additional copies of the Offer to Purchase, the First Supplement, the Letter of Transmittal, and the Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 may be directed to the Information Agent or the Dealer Managers at their respective addresses set forth below. 12

11. LOST, DESTROYED OR STOLEN CERTIFICATES. If any certificate representing Shares or Rights has been lost, destroyed or stolen, the shareholder should promptly notify the Depositary by checking the box immediately preceding the special payment/special delivery instructions and indicating the number of Shares or Rights lost. The shareholder will then be instructed as to the steps that must be taken in order to replace the certificate. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost or destroyed certificates have been followed. IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE COPY HEREOF (TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) MUST BE RECEIVED BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE (AS DEFINED IN THE FIRST SUPPLEMENT). IMPORTANT TAX INFORMATION Under federal income tax law, a shareholder whose tendered Shares or Rights are accepted for payment is required to provide the Depositary with such stockholder's correct TIN on the Substitute Form W-9. If such shareholder is an individual, the TIN is such stockholder's social security number. If the Depositary is not provided with the correct TIN, the shareholder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, payments that are made to such shareholder with respect to Shares purchased pursuant to the Offer may be subject to backup withholding. Certain shareholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, that stockholder must submit a statement, signed under penalty of perjury, attesting to that individual's exempt status. Such statements may be obtained from the Depositary. All exempt recipients (including foreign persons wishing to qualify as exempt recipients) should see the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional instructions. If backup withholding applies, the Depositary is required to withhold 31% of any payments made to the stockholder. Backup withholding is not an additional tax. Rather, the tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained. PURPOSE OF SUBSTITUTE FORM W-9 To prevent backup federal income tax withholding on payments that are made to a stockholder with respect to Shares purchased pursuant to the Offer, the stockholder is required to notify the Depositary of his or her correct TIN by completing the form certifying that the TIN provided on the Substitute Form W-9 is correct. WHAT NUMBER TO GIVE THE DEPOSITARY The stockholder is required to give the Depositary the social security number or employer identification number of the record owner of the Shares. If the Shares are in more than one name or are not in the name of the actual owner, consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional guidelines on which number to report. 13

If a Distribution Date has occurred, a tender of Shares without Rights constitutes an agreement by the tendering shareholder to deliver certificates representing a number of Rights equal to the number of Shares tendered pursuant to the Offer to the Depositary within a period ending three New York Stock Exchange trading days after the date certificates for Rights are distributed to shareholders, all as provided in Section 3 of the Offer to Purchase, as amended. Offeror reserves the right to require that it receive these certificates prior to accepting Shares for payment. Payment for Shares tendered and purchased pursuant to the Offer will be made only after timely receipt by the Depositary of, among other things, these certificates, if the certificates have been distributed to holders of Shares. Offeror will not pay any additional consideration for the Rights tendered pursuant to the Offer. SHARES MAY BE TENDERED ONLY BY THE PROPER EXECUTION AND COMPLETION OF THE LETTER OF TRANSMITTAL.

APPENDIX 4 Contact: Mark Greenberg (973) 455-5445 72% OF AMP SHARES ARE TENDERED TO ALLIEDSIGNAL, A MAJOR VICTORY ---------------- ALLIEDSIGNAL AMENDS OFFER; WILL PAY $44.50 CASH FOR 40 MILLION AMP SHARES (18%), NOT CONDITIONAL ON REDEMPTION OF POISON PILL; WILL RESUME CONDITIONAL OFFER FOR REMAINING AMP SHARES FOLLOWING PURCHASE OF 18% ---------------- ALSO AMENDS CONSENT SOLICITATION TO ADD BYLAW CHANGE TO REMOVE POISON PILL AUTHORITY FROM AMP BOARD ---------------- ACTIONS REFLECT ALLIEDSIGNAL'S FIRM RESOLVE TO COMPLETE ACQUISITION OF AMP MORRIS TOWNSHIP, New Jersey, September 14, 1998--AlliedSignal Inc. [NYSE: ALD] announced today that 157,391,059 shares of AMP Incorporated [NYSE: AMP]--72% of the total outstanding--have been tendered to AlliedSignal by AMP shareowners. "AMP's shareowners have spoken decisively in favor of AlliedSignal's proposed transaction," said Lawrence A. Bossidy, Chairman and Chief Executive Officer of AlliedSignal. "In the face of AMP's plea to shareowners not to tender their shares," said Bossidy, "this is an exceptionally strong message that AMP shareowners want the right to decide for themselves whether to sell. It is a vote of no confidence in management's restructuring plan

-2- and a mandate in favor of AlliedSignal's offer. We're hopeful that the AMP board will now be responsible to its shareowners," said Bossidy. Since AMP's refusal to redeem the poison pill prevents AlliedSignal from purchasing more than 20% of the outstanding shares, AlliedSignal will proceed immediately to purchase as many as it can without triggering AMP's poison pill. Accordingly, AlliedSignal announced today that it is amending its tender offer to purchase up to 40 million AMP shares at $44.50 per share in cash, even if the poison pill is not redeemed. "Acquiring these shares will advance our plan to acquire the remaining shares of AMP as soon as practical," said Bossidy. The $1.8-billion amended tender offer will expire at midnight, New York City time, on September 25, 1998, unless extended. If the offer is successful, AlliedSignal will own 18% of AMP by October 15, the record date set by AMP for AlliedSignal's consent solicitation. AlliedSignal intends to continue its efforts to complete the acquisition of AMP by all available means, including a tender offer of $44.50 in cash per share for all of AMP's remaining shares, conditioned on the removal of the poison pill. AlliedSignal also announced today that it will amend its previously announced shareowner consent solicitation to add a proposal that AMP shareowners amend the bylaws of AMP to remove from AMP's board of directors any authority with respect to AMP's poison pill. Instead, the poison pill power would be vested in new representatives approved by AMP shareowners. These representatives would restore shareowner democracy to AMP by ensuring that the poison pill could not be used to deny shareowners the right to decide for themselves whether to take advantage of a cash tender offer for all of AMP's shares.

-3- "Our amended tender offer and consent solicitation demonstrate our firm resolve to complete the acquisition of AMP," said Bossidy. Shareowners who have already tendered need not take any further action to take advantage of the amended offer. If more than 40 million AMP shares are tendered under the amended offer, AlliedSignal will prorate its purchases among all tendered shares. AMP shareowners will receive amended tender offer materials from AlliedSignal explaining the offer. Any shares not purchased will be returned to AMP shareowners following the September 25 expiration of the amended offer. AMP shareowners will then be able to tender their remaining shares in the subsequent offer for all remaining AMP shares. This news release does not constitute a solicitation of a proxy, consent or authorization for or with respect to a meeting of the company's shareowners or any action in lieu thereof. Any such solicitations will be made only pursuant to separate materials in compliance with the requirements of Section 14(a) of the Securities Exchange Act of 1934, as amended. Lazard Freres & Co. LLC and Goldman, Sachs & Co. are the Dealer Managers for the offer, the complete terms and conditions of which are available by contacting the Information Agent, Morrow & Co., Inc. at (800) 662-5200.

APPENDIX 5 September 14, 1998 [ALLIEDSIGNAL LETTERHEAD] VIA FACSIMILE AND BY HAND - -------------------------- AMP Incorporated 470 Friendship Road Harrisburg, PA 17111 Attention: David F. Henschel, Corporate Secretary and Associate General Legal Counsel Skadden, Arps, Slate, Meagher & Flom, LLP 919 Third Avenue New York, NY 10022 Attention: Peter Allan Atkins, Esq. Gentlemen: In accordance with the agreement between AlliedSignal Inc. ("AlliedSignal") and AMP Incorporated ("AMP"), dated September 4, 1998, AlliedSignal hereby gives notice that it is filing today with the Securities and Exchange Commission (the "SEC") an amendment to its preliminary consent solicitation statement ("Consent Solicitation Statement") with respect to its intended solicitation of written consents from AMP's shareholders for certain proposals. The amendment adds one proposal (the "additional proposal") to the proposals specified in my letter of August 11, 1998 (the "original proposals"). Both the original proposals and the additional proposal are described in the Consent Solicitation Statement, a copy of which is enclosed for your reference. AlliedSignal will not seek to have the Consent Solicitation Statement declared effective any sooner than September 21, 1998. AlliedSignal's consent solicitation is designed to remove the obstacles confronting the $44.50 per share cash offer by AlliedSignal for AMP stock. AlliedSignal, by letter of August 11, 1998, requested that AMP's Board of Directors fix a record date for determining shareholders entitled to consent to corporate action in writing without a meeting. On August 20, 1998, AMP's Board fixed October 15, 1998 as the record date for the solicitation. On the same date, however, AMP's Board also changed AMP's Rights Agreement. The changes included a nonredemption provision, purporting to make the rights issued pursuant to the Rights Agreement non-redeemable by any directors, even "disinterested" directors, if a majority of AMP's Board are persons other than present AMP directors or their designees.

The additional proposal is designed to make the Rights Agreement, as amended, inapplicable to any tender offer that results in the offeror becoming the beneficial owner of a majority of AMP shares as well as to any merger receiving the requisite vote of AMP shareholders. Because the additional proposal has the same objective as the original proposals, because it is related in purpose and effect to the original proposals, and because it arose only in response to changes initiated by AMP as a result of the original proposals, AlliedSignal will proceed on the basis that the record date of October 15, 1998 fixed by AMP's Board for the original solicitation applies to the additional proposal. That date is also more than adequate to ensure that all material information is available to AMP shareholders before they make any decisions on the proposals. In that regard, AlliedSignal today is making a public announcement of its proposals and, as noted above, is filing the Consent Solicitation Statement with the SEC. The October 15 record date thus will provide AMP's shareholders more than 30 days' notice of the proposals and will allow AMP to comply with all applicable SEC and New York Stock Exchange rules. AlliedSignal requests that AMP promptly provide written confirmation to the undersigned that October 15, 1998 is the record date for determining those shareholders entitled to consent in writing without a meeting to the additional proposal. In the event that Section 1.7.2 of the AMP Bylaws is interpreted to require a separate request to fix the record date for the additional proposal, AlliedSignal, as the record holder of 100 shares of AMP common stock, hereby requests, pursuant to Section 1.7.2 of the AMP Bylaws, that AMP's Board of Directors fix October 15, 1998 as the record date for determining shareholders entitled to consent in writing without a meeting to the corporate action specified in the additional proposal. If you have any questions, please call the undersigned at (973) 455-5513, Arthur Fleischer, Jr., Esq. at (212) 859-8120, or Charles M. Nathan, Esq. at (212) 859-8334. Very truly yours, Peter Kreindler, Esq. ---------------------------- Peter Kreindler, Esq. Senior Vice President, General Counsel and Secretary
