         This announcement is neither an offer to purchase nor a solicitation of
an offer to sell Shares (as defined below). The Offer (as defined below) is
being made solely by the Offer to Purchase, dated March 22, 1995, and the
related Letter of Transmittal, and is being made to all holders of Shares.
Purchaser (as defined below) is not aware of any state where the making of the
Offer is prohibited by administrative or judicial action pursuant to any valid
state statute. If Purchaser becomes aware of any valid state statute prohibiting
the making of the Offer or the acceptance of Shares pursuant thereto, Purchaser
will make a good faith effort to comply with any such state statute. If, after
such good faith effort, Purchaser cannot comply with any such state statute, the
Offer will not be made to (nor will tenders be accepted from or on behalf of)
the holders of Shares in such state.


                      Notice of Offer to Purchase for Cash
                     All Outstanding Shares of Common Stock
                                       of
                               Amdura Corporation
                                       at
                              $2.30 Net Per Share
                                       by
                              ADU Acquisition Inc.
                     an indirect wholly owned subsidiary of
                                    FKI plc

         ADU Acquisition Inc., a Delaware corporation ("Purchaser") and an
indirect wholly owned subsidiary of FKI plc, a company organized under the laws
of England ("Parent"), is offering to purchase all outstanding shares of common
stock, par value $.01 per share (the "Shares"), of Amdura Corporation, a
Delaware corporation (the "Company"), at a price of $2.30 per Share, net to the
seller in cash, upon the terms and subject to the conditions set forth in the
Offer to Purchase, dated March 22, 1995 (the "Offer to Purchase"), and in the
related Letter of Transmittal (which together constitute the "Offer"). Following
the Offer, Purchaser intends to effect the Merger described below.

- -------------------------------------------------------------------------------
    The Offer and withdrawal rights will expire at 12:00 midnight, New York
     City time, on Wednesday, April 19, 1995, unless the Offer is extended.
- -------------------------------------------------------------------------------

         The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the expiration of the Offer at least a
majority of the then outstanding Shares on a fully diluted basis (the "Minimum
Condition"). The Offer is also conditioned upon, among other things, the
expiration or termination of any applicable antitrust waiting periods.

         The Offer is being made pursuant to an Agreement and Plan of Merger,
dated as of March 15, 1995 (the "Merger Agreement"), among Parent, Purchaser and
the Company. The Merger Agreement provides that, among other things, as soon as
practicable after the purchase of Shares pursuant to the Offer and the
satisfaction of the other conditions set forth in the Merger Agreement and in
accordance with relevant provisions of the General Corporation Law of the State
of Delaware ("Delaware Law"), Purchaser will be merged with and into the Company
(the "Merger"). Following consummation of the Merger, the Company will continue
as the surviving corporation (the "Surviving Corporation") and will become an
indirect wholly owned subsidiary of Parent. At the effective time of the Merger
(the "Effective Time"), each Share issued and outstanding immediately prior to
the Effective Time (other than Shares held in the treasury of the Company,
Shares owned by Purchaser, Parent or any direct or indirect wholly owned
subsidiary of Parent or of the Company, and Shares held by stockholders who
shall have demanded and perfected appraisal rights under Delaware Law) will be
cancelled and converted automatically into the right to receive $2.30 in cash,
or any higher price that may be paid per Share in the Offer, without interest
(the "Merger Consideration").

<PAGE>

         The Board of Directors of the Company (the "Board") unanimously has
determined that each of the Offer and the Merger is fair to, and in the best
interests of, the stockholders of the Company and recommends that stockholders
accept the Offer and tender their Shares pursuant to the Offer.

         Under the Company's Certificate of Incorporation and Delaware Law, the
affirmative vote of the holders of a majority of the outstanding Shares is
required to approve and adopt the Merger Agreement and the Merger. If the
Minimum Condition is satisfied, Purchaser will have sufficient voting power to
cause the approval and adoption of the Merger Agreement and the transactions
contemplated thereby without the affirmative vote of any other stockholder.

         Simultaneously with entering into the Merger Agreement, Purchaser and
certain stockholders of the Company who, as of March 15, 1995, owned (either
beneficially or of record) Shares constituting approximately 66.5% of the
outstanding Shares (54.2% on a fully diluted basis) (the "Stockholders") entered
into a Stockholders Agreement, dated as of March 15, 1995, pursuant to which,
upon the terms set forth therein, each Stockholder has agreed to tender and
sell, in accordance with the terms of the Offer, all Shares owned (beneficially
or of record) by such Stockholder. Each Stockholder has agreed not to withdraw
his Shares unless (a) the Board or any committee thereof shall have withdrawn or
modified in any manner adverse to Purchaser or Parent its approval or
recommendation of the Offer, the Merger, the Merger Agreement or any other
transaction contemplated by the Merger Agreement in order to approve any Third
Party Transaction which the Board determines in the exercise of its good faith
judgment and after consultation with independent legal counsel and the Company's
financial advisors to be more favorable to the Company's stockholders than the
Offer and the Merger taken together, (b) the Merger Agreement is terminated, (c)
the Merger Agreement is amended in any way which adversely affects such
Stockholder, or (d) such Stockholder's Shares have not been accepted for payment
and paid for by June 13, 1995. "Third Party Transaction" is defined to mean any
of the following: (i) the acquisition of the Company by merger, consolidation or
other business combination transaction by any person other than Parent,
Purchaser or any affiliate thereof (a "Third Party"); (ii) the acquisition by
any Third Party of 50% or more of the outstanding stock or all or a substantial
part (other than in the ordinary course of business) of the assets of a material
Subsidiary; (iii) the acquisition by a Third Party of 50% or more of the
outstanding Shares, whether by tender offer, exchange offer or otherwise; (iv)
the adoption by the Company of a plan of liquidation or the declaration or
payment of an extraordinary dividend; or (v) the repurchase by the Company or
any of its Subsidiaries of 50% or more of the outstanding Shares. Also,
simultaneously with entering into the Merger Agreement, Purchaser and certain of
the Stockholders who as of March 15, 1995 owned (either beneficially or of
record) approximately 46.6% of the outstanding Shares (38.0% on a fully diluted
basis) entered into a Supplemental Stockholders Agreement, dated as of March 15,
1995, in which such Stockholders have agreed that if the Offer is terminated
because of the failure of any condition thereof and the Company effects a Third
Party Transaction with any person other than Parent or any of its subsidiaries
within 180 days thereafter, then each such Stockholder will pay to Purchaser 50%
of the excess, if any, of the amount per Share received by the Stockholder as a
result of such transaction over $2.30 per Share.

         For purposes of the Offer, Purchaser will be deemed to have accepted
for payment (and thereby purchased) Shares validly tendered and not withdrawn
as, if and when Purchaser gives oral or written notice to First Fidelity Bank,
N.A. (the "Depositary") of Purchaser's acceptance for payment of such Shares
pursuant to the Offer. Upon the terms and subject to the conditions of the
Offer, payment for Shares accepted for payment pursuant to the Offer will be
made by deposit of the purchase price therefor with the Depositary, which will
act as agent for tendering stockholders for the purpose of receiving payments
from Purchaser and transmitting such payments to tendering stockholders whose
Shares have been accepted for payment. Under no circumstances will interest on
the purchase price for Shares be paid, regardless of any delay in making such
payment. In all cases, payment for Shares tendered and accepted for payment
pursuant to the Offer will be made only after timely receipt by the Depositary
of (i) the certificates evidencing such Shares (the "Share Certificates") or
timely confirmation of a book-entry transfer of such Shares into the
Depositary's account at one of the Book-Entry Transfer Facilities (as defined in
Section 2 of the Offer to Purchase) pursuant to the procedures set forth in
Section 3 of the Offer to Purchase, (ii) the Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or an Agent's Message (as defined in Section 2 of the
Offer to Purchase) in connection with a book-entry transfer, and (iii) any other
documents required by the Letter of Transmittal.

         Subject to the terms of the Merger Agreement, Purchaser expressly
reserves the right, at any time and from time to time, to extend for any reason
the period of time during which the Offer is open, including the occurrence of
any of the conditions specified in Section 14 of the Offer to Purchase, by
giving oral or written notice of such extension to the Depositary. Any such
extension will be followed as promptly as practicable by public announcement
thereof, such announcement to be made no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled expiration date of
the Offer. During any such extension, all Shares previously tendered and not
withdrawn will remain subject to the Offer, subject to the rights of a tendering
stockholders to withdraw such stockholder's Shares.

         Tenders of Shares made pursuant to the Offer are irrevocable except
that Shares may be withdrawn at any time prior to 12:00 Midnight, New York City
time, on Wednesday, April 19, 1995 (or the latest time and date at which the
Offer, if extended by Purchaser, shall expire) and, unless theretofore accepted
for payment by Purchaser pursuant to the Offer, may also be withdrawn at any
time after June 20, 1995. For the withdrawal to be effective, a written,
telegraphic, or facsimile transmission notice of withdrawal must be timely
received by the Depositary at one of its addresses set forth on the back cover
page of the Offer to Purchase. Any such notice of withdrawal must specify the
name of the person who tendered the Shares to be withdrawn, the number of Shares
to be withdrawn and the name of the registered holder of such Shares, if
different from that of the person who tendered such Shares. If Share
Certificates evidencing Shares to be withdrawn have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such Share
Certificates, the serial numbers shown on such Share Certificates must be
submitted to the Depositary and the signatures) on the notice of withdrawal must
be guaranteed by an Eligible Institution (as defined in Section 3 of the Offer
to Purchase), unless such Shares have been tendered for the account of an
Eligible Institution. If Shares have been tendered pursuant to the procedure for
book-entry transfer as set forth in Section 3 of the Offer to Purchase, any
notice of withdrawal must specify the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Shares. All
questions as to the form and validity (including the time of receipt) of any
notice of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination will be final and binding.

         The information required to be disclosed by Rule 14d-6(e)(1)(vii) of
the General Rules and Regulations under the Securities Exchange Act of 1934, as
amended, is contained in the Offer to Purchase and is incorporated herein by
reference.

         The Company has provided Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
holders of Shares. The Offer to Purchase and the related Letter of Transmittal

in a clearing agency's security position listing for subsequent transmittal to
