Dear Stockholder:
 
     As you may be aware, on August 11, 1997 NATIONAL SANITARY SUPPLY COMPANY
(the "Company") entered into an Agreement and Plan of Merger (the "Merger
Agreement") with UNISOURCE WORLDWIDE, INC. ("Unisource") and TFBD, INC., a
wholly-owned subsidiary of Unisource, providing for the merger (the "Merger") of
TFBD, Inc. with and into the Company. The Merger Agreement is attached as Annex
A to the accompanying Information Statement. The closing of the Merger is
expected to occur during September 1997, subject to the satisfaction of certain
closing conditions. Under the Merger Agreement, each share of the Common Stock,
par value $1.00 per share, of the Company (the "Company Common Stock")
outstanding at the closing of the Merger will be converted into the right to
receive $21.00 in cash, without interest (the "Merger Consideration"). YOU WILL
BE RECEIVING ADDITIONAL INFORMATION AT A LATER TIME ON HOW TO RECEIVE PAYMENT
FOR YOUR SHARES OF COMMON STOCK IN CONNECTION WITH THE MERGER.
 
     The Board of Directors of the Company has approved the Merger of TFBD, Inc.
with and into the Company. Chemed Corporation, owning beneficially and of record
approximately 82% of the issued and outstanding shares of the Company Common
Stock, has provided its written consent and approval of the Merger, thereby
satisfying the requirements of the Delaware General Corporation Law and the
Company's Certificate of Incorporation for stockholder approval of the Merger.
For this reason, the Company is not calling a special meeting of the
stockholders in respect of the proposed Merger and is not asking you for a proxy
or consent.
 
     Stockholders of the Company do have the right to dissent from the Merger
under and pursuant to Section 262 of the Delaware General Corporation Law.
 
     WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US A
PROXY. STOCKHOLDERS ARE URGED TO READ CAREFULLY THIS INFORMATION STATEMENT IN
ITS ENTIRETY.
 
     The attached Information Statement is being provided to you pursuant to

Very truly yours,

<PAGE>   6
 
appraisal rights under Delaware law) will automatically be converted into the

by an Exchange Agent to be appointed by Unisource to all stockholders of the
Company under separate cover promptly following the Effective Time. The Letter
of Transmittal must be completed and returned as directed therein along with
certificates representing the shares of Company Common Stock covered thereby.
Checks for the Merger Consideration will be sent to stockholders as soon as
practicable after receipt of Letters of Transmittal and stock certificates.
Detailed instructions concerning the procedure for receipt of the Merger
Consideration will be set forth in the Letter of Transmittal.
 
APPRAISAL RIGHTS
 
     Under the DGCL, holders of shares of Company Common Stock who otherwise
strictly comply with the applicable requirements of the DGCL may dissent from
the Merger and demand payment in cash of the fair value of their shares of
Company Common Stock. See "APPRAISAL RIGHTS" and Annex B.
 
THE MERGER
 
     Background to the Merger.  For a description of events leading to the
approval of the Merger Agreement by the Board of the Company, see "THE
MERGER -- Background of the Merger".
 
     Approval of the Board.  On August 8, 1997, the Board of the Company
unanimously determined that the Merger Agreement and the Merger were fair to and
in the best interests of the stockholders of the Company and approved and
adopted the Merger Agreement and the Merger. See "THE MERGER -- Background of
the Merger".
 
     Interest of Certain Persons in the Merger.  The Merger Agreement contains
as a condition to the obligations of Unisource and Merger Sub to consummate the
Merger a condition that prior to the Effective Time Unisource shall have entered
into employment agreements with each of the senior management employees of the
Company, in each case in form and substance satisfactory to Unisource. Unisource
may waive this condition. Unisource has not yet offered to enter into employment
agreements with the Company's senior management employees. See "THE
MERGER -- Employment Agreements".
 
     Each of the executive officers of the Company except one hold stock options
to purchase Company Common Stock. All of such options will be canceled in
exchange for a cash payment to the holder of an amount equal to the excess of
$21.00 over the exercise price under such option. The executive officers other
than one individual also hold restricted shares granted under the Company's
Restricted Stock Award Program (the "Program"). The vesting restrictions
applicable to such shares, which generally lapse over a period of years, will
lapse due to the change of control features of the Program by reason of the
change of control that will result in the Company upon consummation of the
Merger. As a result all such shares will vest as of the Effective Time and the
holders of such shares will receive $21.00 for each such share. See "THE
MERGER -- Stock Plans".
 
     The DGCL permits a company to indemnify its officers and directors under
certain specified circumstances and also requires such indemnification under
specified circumstances. In addition, as permitted by law, the Company's
Certificate of Incorporation contains a provision eliminating the personal
liability of a director to the Company and its stockholders for monetary damages
for breach of fiduciary duty as a director, subject to certain statutory
exceptions. The Company's Certificate of Incorporation and Bylaws and separate
Indemnity Agreements also contain provisions providing for mandatory
indemnification of officers and directors in certain circumstances. However
there are no provisions in the Merger Agreement requiring Unisource to cause the
Company, as the surviving corporation, to indemnify and hold harmless the
present and former officers and directors of the Company in respect of any of
their acts or omissions occurring prior to the Effective Time. All such officers
and directors are entitled to receive indemnification from Chemed with respect
to the aforesaid acts or omissions. See "THE MERGER -- No Contractual
Indemnification Rights".
 
                                        2

     Opinions of Financial Advisors.  The Board of Directors of the Company did
not obtain any opinions from any financial advisors that the consideration to be
received by the stockholders of the Company in the Merger is fair from a
financial point of view. See "THE MERGER -- Recommendation of Board".
 
     Conditions to the Merger.  The Merger Agreement provides that the
respective obligations of each party to effect the Merger are subject to the
satisfaction or waiver on or prior to the Merger becoming effective (the
"Effective Time") of the following conditions: (1) The Merger Agreement shall
have been adopted by the stockholders of the Company in accordance with Delaware
law, (2) any applicable waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), relating to the Merger
shall have expired, (3) no provision of any applicable law or regulation and no
judgment, injunction, order or decree shall prohibit the consummation of the
Merger, (4) all actions by or in respect of or filings with any governmental
body, agency, official or authority required to permit the consummation of the
Merger shall have been obtained, and (5) the performance by the parties in all
material respects of their respective obligations under the Merger Agreement
prior to the Effective Time and the truth in all material respects of the
parties' representations and warranties at the Effective Time. The condition set
forth in clause (1) above has been satisfied by the execution of the
Stockholder's Consent by Chemed the holder of 82% of the Company Common Stock.
 
     In addition the obligations of Unisource and Merger Sub to effect the
Merger are subject to the satisfaction or waiver of the further following
conditions: (1) no action shall be instituted or pending by anyone before any
tribunal challenging the Merger in any way or seeking to restrain or prohibit
Unisource's ownership or operation of the Company or to force a disposition or
segregation of any material part of the Company's business or that would
otherwise materially adversely affect the Company, Unisource or Merger Sub, (2)
no action shall have been taken or any law or injunction proposed, enacted or
otherwise enforced applicable to the Merger by any tribunal, authority or agency
that would likely result in the consequences described in (1) above, (3) Chemed
shall have executed and delivered the Indemnity and Tax Matters Agreements,
forms of which are attached to Annex A hereto, (4) Chemed shall have executed a
Non-Compete Agreement in form acceptable to Unisource, (5) Unisource shall have

the Company to be designated by Unisource, (6) Chemed shall have entered into a
Transitional Services Agreement with Unisource providing for the continuation of
certain employee benefits by Chemed to employees of the Company for a period of
time to be agreed upon between them, but in form and substance satisfactory to
Unisource, (7) Unisource shall have completed environmental due diligence to its
satisfaction, (8) the Company shall have received all Required Consents (as
defined in the Merger Agreement), and (9) Unisource shall have received the
resignation of the officers and directors of the Company.
 
   
     Regulatory Matters.  The Federal Trade Commission granted early termination
of the waiting period under the HSR Act on August 29, 1997. No other federal or
state regulatory approval is required for the Merger. See "REGULATORY MATTERS."
    
 
     Certain Federal Income Tax Consequences.  The receipt of the right to
receive cash by stockholders of the Company pursuant to the Merger Agreement
will be a taxable transaction for Federal Income Tax purposes under the Internal
Revenue Code of 1986, as amended (the "Code"), and may also be a taxable
transaction under applicable state, local, foreign and other tax laws. See "THE
MERGER -- Certain Federal Income Tax Consequences".
 
SOURCE AND AMOUNT OF FUNDS
 
   
     The total amount of funds required to fund the Merger Consideration, to
cancel and pay for all employee stock options, to pay fees and expenses related
to the Merger and to assume or repay existing debt of the Company is estimated
to be approximately $163 million. Such funds will be obtained through an
existing credit agreement with Unisource's bank. See "SOURCE AND AMOUNT OF
FUNDS".

NATIONAL SANITARY SUPPLY COMPANY
NOTES TO CONSOLIDATED SELECTED FINANCIAL DATA:
 
(1) MAJOR CUSTOMER. During the first quarter of 1996, the Company lost the
    disposable foodservice products business with a fast-food restaurant chain.
    Since then, the Company's gross profit margin has improved and operating
    expenses as a percent of sales have increased. The change reflects the loss
    of the low-margin and low-operating-expense business with this customer.
    Sales to this customer are summarized below:

                                    GENERAL
 
     This Information Statement is being delivered in connection with the merger
of Merger Sub into the Company. As a result of the Merger, the Company will be a
wholly-owned subsidiary of Unisource, and each outstanding share of Company
Common Stock (other than Shares that are owned by the Company, Unisource or a
subsidiary of Unisource or by stockholders who have validly perfected their
appraisal rights under Delaware law) will be converted into the right to receive
$21.00 in cash. A copy of the Merger Agreement is attached hereto as Annex A.
 
               REQUIRED VOTE; WRITTEN CONSENT IN LIEU OF MEETING
 
     The DGCL provides that the adoption of any plan of merger by the Company
requires the approval of the Company's Board of Directors and the affirmative
vote of the holders of a majority of the outstanding shares of the Company
Common Stock entitled to vote thereon. The Board of Directors of the Company has
authorized and approved the Merger Agreement and the Merger. Chemed owns and has
the right to vote 5,144,551 shares of Company Common Stock, or approximately 82%
of the outstanding shares thereof. On August 8, 1997 Chemed executed a written
consent in favor of the approval and adoption of the Merger Agreement. Pursuant
to Section 228 of the DGCL and the Company's Certificate of Incorporation, no
additional approval by the Company stockholders is required with respect to the
Merger Agreement.
 
     The Merger will become effective upon the filing of a certificate of merger
with the Secretary of State of the State of Delaware in accordance with the
DGCL. As used in this Information Statement, "Effective Time" means the
effective time of the Merger under the DGCL.
 
                 PROCEDURE FOR RECEIPT OF MERGER CONSIDERATION
 
     Valid Surrender of Shares.  At the Effective Time, each outstanding share
of Company Common Stock (other than shares owned by the Company, Unisource or
any subsidiary of Unisource or by stockholders who have validly perfected their
appraisal rights under Delaware law) will automatically be converted into the
right to receive the Merger Consideration. A Letter of Transmittal will be sent
to the Company stockholders under separate cover promptly following the
Effective Time. The Transmittal Letter will contain instructions with respect to
obtaining the Merger Consideration in exchange for shares of the Company Common
Stock. For a stockholder validly to surrender shares of Company Common Stock
pursuant to the Merger, a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), together with any required signature
guarantees and any other required documents, must be received by the Exchange
Agent at one of its addresses set forth on the Letter of Transmittal and either
certificates for tendered shares must be received by the Exchange Agent named in
the Letter of Transmittal at one of such addresses or such shares must be
delivered pursuant to the procedure for book-entry transfer set forth below (and
a Book-Entry Confirmation (as defined below) received by the Exchange Agent).
 
     Book-Entry Transfer.  The Exchange Agent will establish an account with
respect to the shares of Company Common Stock at The Depository Trust Company
and the Philadelphia Depository Trust Company (the "Book-Entry Transfer
Facilities") for purposes of the Merger. Any financial institution that is a
participant in any of the Book-Entry Transfer Facilities' systems may make
book-entry delivery of such shares by causing a Book-Entry Transfer Facility to
transfer such shares into the Exchange Agent's account in accordance with such
Book-Entry Transfer Facility's procedures for such transfer. However, although
delivery of shares may be effected through book-entry transfer into the Exchange
Agent's account at a Book-Entry Transfer Facility, the Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees and any other required documents, must, in any case, be
transferred to, and received by, the Exchange Agent at one of its addresses set
forth on the Transmittal Letter, or the surrendering stockholder must comply
with the guaranteed delivery procedure described below. The confirmation of a
book-entry transfer of shares into the Exchange Agent's account at a Book-Entry
Transfer Facility as described above is referred to herein as a "Book-Entry
Confirmation". DELIVERY OF DOCUMENTS TO A BOOK-ENTRY
 
                                        7
<PAGE>   12
 
TRANSFER FACILITY IN ACCORDANCE WITH SUCH BOOK-ENTRY TRANSFER FACILITY'S
PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
 
     Signature Guarantees.  No signature guarantee is required on the Letter of
Transmittal if (1) the Letter of Transmittal is signed by the registered holder
of shares (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) tendered therewith and
such registered holder has not completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on the
Letter of Transmittal or (2) such shares are tendered for the account of a firm
that is a member of a registered national securities exchange or of the National
Association of Securities Dealers, Inc. (the "NASD"), or a commercial bank or
trust company having an office or correspondent in the United States or by any
other "eligible guarantor institution", as such term is defined in Rule 17Ad-15
under the Exchange Act (each, an "Eligible Institution"). In all other cases,
all signatures on the Letters of Transmittal must be guaranteed by an Eligible
Institution. If the certificates for shares are registered in the name of a
person other than the signer of the Letter of Transmittal, or if payment is to
be made or certificates for shares not tendered or not accepted for payment are
to be issued to a person other than the registered holder of the certificates
surrendered, the surrendered certificates must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name or names of
the registered holders or owners appear on the certificates, with the signatures
on the certificates or stock powers guaranteed as aforesaid.
 
     Determination of Validity.  All questions as to the validity, form,
eligibility and acceptance of any surrender of shares will be determined by
Unisource in its sole discretion, which determination will be final and binding.
 
     Backup Withholding.  In order to avoid "backup withholding" of Federal
income tax on payments of cash pursuant to the Merger, a stockholder
surrendering shares in the Merger must provide the Exchange Agent with such
stockholder's correct taxpayer identification number ("TIN") on a Substitute
Form W-9 and certify under penalties of perjury that such TIN is correct and
that such stockholder is not subject to backup withholding. Certain stockholders
(including, among others, all corporations and certain foreign individuals and
entities) are not subject to backup withholding. If a stockholder does not
provide its correct TIN or fails to provide the certifications described above,
the Internal Revenue Service ("IRS") may impose a penalty on such stockholder
and payment of cash to such stockholder pursuant to the Merger may be subject to
backup withholding of 31%. All stockholders surrendering shares pursuant to the
Merger should complete and sign the main signature form and the Substitute Form
W-9 included as part of the Letter of Transmittal to provide the information and
certification necessary to avoid backup withholding (unless an applicable
exemption exists and is proved in a manner satisfactory to Unisource and the
Exchange Agent). Noncorporate foreign stockholders 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.
 
                                APPRAISAL RIGHTS
 
     Holders of shares of Company Common Stock are entitled to appraisal rights
in accordance with Section 262 ("Section 262") of the DGCL (which is reproduced
in full in Annex B hereto). Such appraisal rights, if the statutory procedures
are complied with, would result in a judicial determination by the Delaware
Court of Chancery of the "fair value" of the shares of Company Common Stock
("Shares") owned by such holders, together with a fair rate of interest, if any,
to be paid upon the amount determined to be fair value. Any such judicial
determination of the fair value of the Shares could be based upon considerations
other than or in addition to the price to be paid in the Merger and the market
value of the Shares, including asset values, the investment value of the Shares
and any other valuation considerations generally accepted in the investment
community. In Weinberger v. UOP, Inc., the Delaware Supreme Court stated that
"proof of value by any techniques or methods which are generally considered
acceptable in the financial community and otherwise admissible in court" should
be considered in an appraisal proceeding. The Weinberger court also noted that
under Section 262 of the DGCL, fair value is to be determined "exclusive of any
element of value
 
                                        8
<PAGE>   13
 
arising from the accomplishment or expectation of the merger." As a consequence
of the foregoing, the fair value determined for Shares could be the same as or
more or less than the value of the consideration per Share paid pursuant to the
Merger and payment of such consideration would take place subsequent to payment
pursuant to the Merger.
 
     No provision has been made by the Company, Unisource or Merger Sub to allow
access to the Company's files by unaffiliated stockholders or to obtain counsel
or appraisal services at the expense of the Company, Unisource or Merger Sub.
 
THE FOLLOWING SUMMARY IS NOT A COMPLETE STATEMENT OF THE LAW RELATING TO
APPRAISAL RIGHTS AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO ANNEX B. THIS
SUMMARY AND ANNEX B SHOULD BE REVIEWED CAREFULLY BY ANY HOLDER WHO WISHES TO
EXERCISE STATUTORY APPRAISAL RIGHTS OR WHO WISHES TO PRESERVE THE RIGHT TO DO SO
BECAUSE FAILURE TO COMPLY STRICTLY WITH THE PROCEDURES SET FORTH HEREIN AND
THEREIN WILL RESULT IN THE LOSS OF APPRAISAL RIGHTS.
 
     In accordance with Section 262, any stockholder entitled to appraisal
rights may, within 20 days after the date of mailing of this Information
Statement, demand in writing from the Company the appraisal of the fair value of
such stockholder's Shares. Such demand must reasonably inform the Company of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of the fair value of such stockholder's Shares. Any stockholder
(other than a record owner who is acting as a nominee holder for different
beneficial owners) seeking to exercise appraisal rights for a portion, but not
all, of such stockholder's Shares should consult with legal counsel before
taking any such action. The Company believes that Delaware law has not clearly
addressed the ability of such a stockholder to exercise appraisal rights with
respect to a portion, but not all, of such stockholder's Shares. Stockholders
should be aware of the risk that should a stockholder seek to exercise appraisal
rights with respect to a portion, but not all, of such stockholder's Shares, the
Company may assert that by doing so such stockholder has waived such
stockholder's appraisal rights and a Delaware court may find that such
stockholder has so waived such stockholder's appraisal rights. A stockholder who
elects to exercise appraisal rights must mail or deliver such stockholder's
written demand to the President of the Company at 2900 Chemed Center, 255 East
Fifth Street, Cincinnati, Ohio 45202-4790.
 
     A demand for appraisal must be executed by or for the stockholder of
record, fully and correctly, as such stockholder's name appears on the
certificate or certificates representing the stockholder's Shares. If the Shares
are owned of record in a fiduciary capacity, such as by a trustee, guardian, or
custodian, such demand must be executed by the fiduciary. If the Shares are
owned of record by more than one person, as in a joint tenancy or tenancy in
common, such demand must be executed by all joint owners. An authorized agent,
including an agent for two or more joint owners, may execute the demand for
appraisal for a stockholder of record; however, the agent must identify the
record owner and expressly disclose the fact that, in exercising the demand,
such person is acting as agent for the record owner.
 
     A record owner, such as a broker, who holds Shares as a nominee for others,
may exercise appraisal rights with respect to the Shares held for all or less
than all beneficial owners of Shares as to which such person is the record
owner. In such case, the written demand must set forth the number of Shares
covered by such demand. Where the number of Shares is not expressly stated, the
demand will be presumed to cover all Shares outstanding in the name of such
record owner. Beneficial owners who are not record owners and who intend to
exercise appraisal rights should instruct the record owner to comply strictly
with the statutory requirements with respect to the exercise of appraisal
rights.
 
     Within 120 days after the Effective Time, either the Company, as the
surviving corporation in the Merger (the "Surviving Corporation"), or any
stockholder who has complied with the required conditions of Section 262 may
file a petition in the Delaware Court of Chancery (the "Delaware Chancery
Court") demanding a determination of the fair value of the Shares of the
dissenting stockholders. If a petition for an appraisal is timely filed, after a
hearing on such petition, the Delaware Chancery Court will determine which
stockholders are entitled to appraisal rights and will appraise the Shares
formerly owned by such stockholders, determining the fair value of such Shares,
exclusive of any element of value arising from the accomplishment
 
                                        9
<PAGE>   14
 
or expectation of the Merger, together with a fair rate of interest, if any, to
be paid upon the amount determined to be the fair value. In determining such
fair value, the Delaware Chancery Court is to take into account all relevant
factors.
 
     Stockholders considering seeking appraisal should note that the "fair
value" of their Shares determined under Section 262 could be more than, the same
as or less than $21.00 per Share, and that opinions of investment banking firms
as to fairness, from a financial point of view, are not opinions as to fair
value under Section 262. The cost of the appraisal proceeding may be determined
by the Delaware Chancery Court and taxed against the parties as the Delaware
Chancery Court deems equitable in the circumstances. Upon application of a
dissenting stockholder, the Delaware Chancery Court may order that all or a
portion of the expenses incurred by any dissenting stockholder in connection
with the appraisal proceeding, including without limitation, reasonable
attorneys' fees and the fees and expenses of experts, be charged pro rata
against the value of all Shares entitled to appraisal.
 
     From and after the Effective Time, no stockholder who has duly demanded
appraisal in compliance with Section 262 will be entitled to vote for any
purpose the Shares subject to such demand or to receive payment of dividends or
other distributions on such Shares, except for dividends or distributions
payable to stockholders of record at a date prior to the Effective Time.
 
     At any time, within 60 days after the Effective Time, any stockholder shall
have the right to withdraw such stockholder's demand for appraisal and to accept
the terms offered in the Merger Agreement; after this period, a stockholder may
withdraw such stockholder's demand for appraisal only with the consent of the
Company. If no petition for appraisal is filed with the Delaware Chancery Court
within 120 days after the Effective Time, stockholders' rights to appraisal
shall cease, and all stockholders who had previously demanded appraisal shall
thereafter be entitled to receive the Merger Consideration in cash, without
interest thereon, upon surrender of the certificates that formerly represented
their Shares. Inasmuch as the Company has no obligation to file such a petition,
and has no present intention to do so, any stockholder who desires such a
petition to be filed is advised to file it on a timely basis. However, no
petition timely filed in the Delaware Chancery Court demanding appraisal shall
be dismissed as to any stockholder without the approval of the Delaware Chancery
Court, and such approval may be conditioned upon such terms as the Delaware
Chancery Court deems just.
 
FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR PERFECTING
APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.

                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
     Set forth below is a description of the background of the Merger.
 
     In early June 1997 Unisource approached Chemed about a possible combination
with the Company. Preliminary discussions between the parties and
representatives of the Company ensued and Unisource indicated it had a serious
interest in pursuing the acquisition of the Company.
 
     On June 25, 1997 a Confidentiality Agreement was entered into between
Unisource and the Company whereby Unisource agreed to keep confidential its
discussions and negotiations regarding the Merger and all information received
by it concerning the Company.
 
     Thereafter Unisource was given certain confidential information concerning
the Company's business which it used to value the Company and to formulate an
offer to acquire the Company. Site visits to Company facilities were also
conducted.
 
     On July 31, 1997 representatives of Chemed and the Company met with
representatives of Unisource in New York City regarding a potential merger of
the Company with Unisource or one of its affiliates. At this meeting various
issues regarding the Merger were discussed including the valuation of the
Company and the price per share Unisource was willing to pay in the Merger.
Unisource had previously requested that Chemed, in connection with the Merger,
make an election under Sections 338(g) and 338(h)(10) of the Internal Revenue
Code of 1986, as amended (the "Code"), together with comparable elections under
state and local tax laws with respect to the Company and each of its
subsidiaries. Because such an election would result in significant cost to
Chemed, the meeting was adjourned to August 3, 1997 to allow Chemed to evaluate
and further understand the implications of Unisource's request.
 
     A meeting of the representatives of the Company, Chemed and Unisource
reconvened in New York City on August 3, 1997 and at this meeting Unisource and
Chemed agreed to the Merger Consideration of $21.00 per share for each share of
Company Common Stock, to be paid to all stockholders of the Company equally.
Chemed also agreed to make the requested election under Section 338 of the Code
and both Chemed and Unisource agreed to share the negative tax cost of such
election. The parties agreed to a payment of $12,207,000 to Chemed representing
a portion of Chemed's share of such cost.
 
     At the meeting on August 3, 1997 the terms of the Merger Agreement were
negotiated in final form and discussions concerning due diligence, document
preparation and various legal issues were concluded.
 
     Special meetings of the Boards of Directors of the Company and of Chemed
were held on August 8, 1997 at which time the Merger and the terms of the Merger
Agreement were unanimously approved by both Boards of Directors after
presentations by the management of Chemed. The Stockholder's Consent was
executed on August 8, 1997, the Merger Agreement was executed on August 11,
1997, and the transaction was publicly announced on August 11, 1997.
 
RECOMMENDATION OF BOARD
 
     Prior to recommending Unisource's offer to the Boards of the Company and
Chemed, management made inquiries of other potential purchasers of the Company.
Based on the results of these inquiries, management believed and recommended to
both Boards that the transaction with Unisource represented the most
advantageous opportunity for the stockholders of the Company.
 
     On August 8, 1997 the Board of Directors of Chemed, the record and
beneficial owner of approximately 82% of the outstanding shares of Company
Common Stock, also met and approved the Merger and authorized the execution and
delivery of the Stockholder's Consent approving the Merger under the DGCL. The
Boards of Directors of the Company and Chemed in connection with the actions
taken to approve the Merger considered a number of factors, including the
following:
 
                                       11
<PAGE>   16
 
     Financial Condition, Results of Operations, Business and Prospects of the
Company.  The Board of the Company and Chemed considered the financial
condition, results of operations, business and prospects of the Company,
including its prospects if it were to remain independent. They considered the
Company's current strategic plan, including the costs of such plan and the risks
for the Company involved in its implementation. The Board and Chemed also
considered the highly competitive environment in which the Company operates.
 
     Other Potential Transactions.  The Boards of the Company and of Chemed also
considered the fact that no other offers at the price Unisource was willing to
pay for the Company had been received. Although a prior party expressed interest
in considering the possibility of acquiring the Company no formal offer
materialized.
 
     Historical Stock Price Performance.  The Board of the Company and Chemed
reviewed the historical stock price performance of the Company and noted that
the consideration to be received by the Company's stockholders pursuant to the
Merger would represent a premium of approximately 57% over the median sales
price for the first six calendar months of 1997.
 
     Terms and Conditions of the Merger.  The Board of the Company also
considered the terms and conditions of the Merger Agreement including the fact
that the transaction was structured as a cash offer for all shares of Company
Common Stock which would permit all holders of shares of Company Common Stock to
participate on the same basis.
 
     One major condition that Unisource included in the Merger Agreement was
that Chemed would make an irrevocable joint election with Unisource under
Sections 338(g) and 338(h)(10) of the Code together with comparable elections
under state and local tax law. The making of such an election with respect to
the Company and each of its subsidiaries by Chemed would have negative tax
consequences to Chemed as the entity making the election. The election benefits
Unisource as the purchaser of the Company in that it allows Unisource to treat
the acquisition of the Company as an asset acquisition, rather than a stock
acquisition, for federal income tax purposes and thereby to obtain a stepped up
basis for depreciation purposes in the assets of the Company purchased.
 
     The final terms of the Merger Agreement provide that the costs of the
negative tax consequences to Chemed as a result of Chemed being obligated to
make the Section 338(h)(10) election under the Code will be shared by Unisource
and Chemed. The costs of such an election are not being allocated to the
stockholders of the Company other than Chemed. Unisource will make a payment in
the amount of $12,207,000 to Chemed pursuant to the Tax Matters Agreement to
cover a portion of the additional costs imposed as a result of the Section
338(h)(10) election on the day after the Effective Time.
 
     Other Considerations.  The Board of the Company and Chemed also considered
the financial ability of Unisource to consummate the Merger and the fact that
there is no financing contingency in the Merger Agreement. They also considered
the possible impact of the Merger and of alternatives thereto on the Company's
business and prospects, and the fact that following the consummation of the
Merger the current stockholders of the Company will no longer be able to
participate in the increases or decreases in the value of the Company's business
and profits.
 
     The foregoing discussion of the information and factors considered and
given weight by the Boards of Directors of the Company and Chemed is not
intended to be exhaustive. In view of the variety of factors considered in
connection with their evaluation of the Merger, they did not find it practicable
to, and did not, quantify or otherwise assign relative weights to the specific
factors considered in reaching their determination. In addition, individual
members of the Board of the Company and of the Board of Directors of Chemed may
have given different weights to different factors.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Employment Agreements.  The Merger Agreement contains as a condition to the
obligations of Unisource and Merger Sub to consummate the Merger a condition
that prior to the Effective Time Unisource shall have entered into employment
agreements with each of the senior management employees of the Company, in each
case in form and substance satisfactory to Unisource. Unisource may waive this
condition.
 
                                       12
<PAGE>   17
 
Unisource has not yet offered to enter into employment agreements with the
Company's senior management employees.
 
     Confidentiality Agreement.  The Company and Unisource signed a
Confidentiality Agreement dated June 25, 1997 (the "Confidentiality Agreement"),
providing for Unisource to keep confidential its discussions and negotiations
regarding the Merger and all information received by it concerning the Company.
The Merger Agreement terminated the Confidentiality Agreement and instituted an
equivalent covenant of confidentiality on behalf of Unisource in its place.
 
     Stock Plans.  Pursuant to the Merger Agreement, at or immediately prior to
the Effective Time, each outstanding employee stock option to purchase shares of
Company Common Stock granted under any employee stock option or compensation
plan or arrangement of the Company will be canceled, and each holder thereof,
whether or not such stock options are then vested or exercisable, shall be paid
by the Company promptly after the Effective Time for each such option an amount
in cash determined by multiplying (i) the excess, if any, of the Merger
Consideration over the applicable exercise price of such option by (ii) the
number of shares of Company Common Stock such holder could have purchased
(assuming full vesting of all options) had such holder exercised such option in
full immediately prior to the Effective Time, less any taxes required to be
withheld by the Company with respect thereto.
 
     Each of the executive officers of the Company, other than R. B. Garber,
hold stock options to purchase shares. All of such options will be canceled in
exchange for a cash payment to the holder of an amount equal to the excess, if
any, of $21.00 over the exercise price under such option.
 
     All amounts payable pursuant to the terms described in the preceding
paragraph are subject to any required withholding of taxes and will be paid
without interest. The Company agreed in the Merger Agreement to obtain all
consents of the holders of the stock options and to make any amendments to the
terms of such stock option or compensation plans or arrangements as shall be
necessary to effectuate the foregoing. Notwithstanding anything to the contrary
contained in the Merger Agreement, payment shall, at Unisource's request, be
withheld in respect of any stock option with respect to any holder until all
necessary consents are obtained from such holder.
 
     The executive officers, other than R. B. Garber, also hold restricted
shares granted under the Company's Restricted Stock Award Program. The vesting
restrictions applicable to such shares, which generally lapse over a period of
years, will lapse due to the change of control features of the Program by reason
of the change of control that will result in the Company upon consummation of
the Merger. As a result all such shares will vest as of the Effective Time and
the holders of such shares will receive $21.00 for each such share. See "THE
MERGER -- Employment Agreements".
 
     Benefit Plans.  The Merger Agreement provides that Unisource and Chemed
will enter into a Transitional Services Agreement before the Effective Time
pursuant to which Chemed will provide certain employee benefits to employees of
the Company for a period of time to be agreed upon between Unisource and Chemed,
in form and substance satisfactory to Unisource.
 
     No Contractual Indemnification Rights.  There are no provisions in the
Merger Agreement requiring Unisource to cause the Company, as the surviving
corporation, to indemnify and hold harmless the present and former officers and
directors of the Company in respect of any of their acts or omissions occurring
prior to the Effective Time. All such officers and directors are entitled to
receive indemnification from Chemed with respect to the aforesaid acts or
omissions.
 
     Certain Federal Income Tax Consequences.  The receipt of the right to
receive cash by stockholders of the Company pursuant to the Merger Agreement
will be a taxable transaction for Federal income tax purposes under the Code and
may also be a taxable transaction under applicable state, local, foreign and
other tax laws. For Federal income tax purposes, a stockholder will generally
recognize gain or loss equal to the difference between the amount of cash
received by the stockholder pursuant to the Merger and the aggregate tax basis
in the shares of Company Common Stock surrendered by the stockholder and
purchased pursuant to the Merger.
 
                                       13
<PAGE>   18
 
Gain or loss will be calculated separately for each block of such shares
converted into cash pursuant to the Merger.
 
     If shares are held by a stockholder as capital assets, gain or loss
recognized by the stockholder will be capital gain or loss, which will be
long-term capital gain or loss if the stockholder's holding period for such
shares exceeds eighteen months. Under present law, long-term capital gains
recognized by an individual stockholder will generally be taxed at a maximum
Federal marginal tax rate of 20%, and long-term capital gains recognized by a
corporate stockholder will be taxed at a maximum Federal marginal tax rate of
35%.
 
     A stockholder (other than certain exempt stockholders including, among
others, all corporations and certain foreign individuals) that surrenders shares
in the Merger may be subject to 31% backup withholding unless the stockholder
provides its TIN and certifies that such number is correct or properly certifies
that it is awaiting a TIN. A stockholder that does not furnish its TIN may be
subject to a penalty imposed by the IRS. Each stockholder should complete and
sign the Substitute Form W-9 included as part of the Letter of Transmittal so as
to provide the information and certification necessary to avoid backup
withholding.
 
     If backup withholding applies to a stockholder, the Exchange Agent is
required to withhold 31% from payments to such stockholder. Backup withholding
is not an additional 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 stockholder upon filing an income tax return.
 
     THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE WITH RESPECT TO SHARES
RECEIVED PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS
COMPENSATION OR WITH RESPECT TO HOLDERS OF SHARES WHO ARE SUBJECT TO SPECIAL TAX
TREATMENT UNDER THE CODE, SUCH AS NON-U.S. PERSONS, LIFE INSURANCE COMPANIES,
TAX-EXEMPT ORGANIZATIONS AND FINANCIAL INSTITUTIONS, AND MAY NOT APPLY TO A
HOLDER OF SHARES IN LIGHT OF ITS INDIVIDUAL CIRCUMSTANCES. STOCKHOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL
OR FOREIGN INCOME AND OTHER TAX LAWS) OF THE MERGER.
 
ACCOUNTING TREATMENT OF THE MERGER
 
     The Merger will be accounted for under the "purchase" method of accounting,
whereby the purchase price for the Company will be allocated to the identifiable
assets and liabilities of the Company and its subsidiaries based on their
respective fair values.
 
                               REGULATORY MATTERS
 
   
     The Federal Trade Commission granted early termination of the waiting
period under the HSR Act on August 29, 1997.
    
 
                              THE MERGER AGREEMENT
 
     The following is a summary of the material terms of the Merger Agreement.
This summary is not a complete description of the terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the full text

otherwise defined herein shall have the meanings assigned to them in the Merger
Agreement.
 
     Conditions to Each Party's Obligation to Effect the Merger.  The Merger
Agreement provides that the respective obligations of each party to effect the
Merger are subject to the satisfaction or waiver on or prior to the Merger
becoming effective (the "Effective Time") of the following conditions: (1) the
Merger Agreement shall have been adopted by the stockholders of the Company in
accordance with Delaware law, (2) any applicable waiting period under the HSR
Act relating to the Merger shall have expired, (3) no
 
                                       14
<PAGE>   19
 
provision of any applicable law or regulation and no judgment, injunction, order
or decree shall prohibit the consummation of the Merger, (4) all actions by or
in respect of or filings with any governmental body, agency, official or
authority required to permit the consummation of the Merger shall have been
obtained, and (5) the performance by the parties in all material respects of
their respective obligations under the Merger Agreement prior to the Effective
Time and the truth in all material respects of the parties' representations and
warranties at the Effective Time. The condition set forth in clause (1) above
has been satisfied by the execution of the Stockholder's Consent by Chemed the
holder of approximately 82% of the Company Common Stock.
 
     In addition, the obligations of Unisource and Merger Sub to effect the
Merger are subject to the satisfaction or waiver of the further following
conditions: (1) no action shall be instituted or pending by anyone before any
tribunal challenging the Merger in any way or seeking to restrain or prohibit
Unisource's ownership or operation of the Company or to force a disposition or
segregation of any material part of the Company's business or that would
otherwise materially adversely affect the Company, Unisource or Merger Sub, (2)
no action shall have been taken or any law or injunction proposed, enacted or
otherwise enforced applicable to the Merger by any tribunal, authority or agency
that would likely result in the consequences described in (1) above, (3) Chemed
shall have executed and delivered the Indemnity and Tax Matters Agreements,
forms of which are attached to Annex A hereto, (4) Chemed shall have executed a

certain employee benefits by Chemed to employees of the Company for a period of
time to be agreed upon between them, but in form and substance satisfactory to
Unisource, and (7) Unisource shall have completed environmental due diligence to
its satisfaction, (8) the Company shall have received all Required Consents (as
defined in the Merger Agreement), and (9) Unisource shall have received the
resignation of the officers and directors of the Company.
 
     Termination of the Merger Agreement.  The Merger Agreement may be
terminated and the Merger contemplated thereby may be abandoned at any time
prior to the Effective Time, notwithstanding approval thereof by the
stockholders of the Company, (1) by mutual written consent of the Company and
Unisource; (2) by either the Company or Unisource, if the Merger has not been
consummated by December 31, 1997, provided that the right to terminate the
Merger Agreement pursuant to this provision is not available to any party whose
breach of any provision of the Agreement results in the failure of the Merger to
be consummated by such time; (3) by either the Company or Unisource, if there is
any law or regulation that makes consummation of the Merger illegal or otherwise
prohibited or if any judgment, injunction, order or decree enjoining Unisource
or the Company from consummating the Merger is entered and such judgment,
injunction, order or decree shall become final and nonappealable; or (4) by
Unisource if either the results of its due diligence of the Company and its
subsidiaries, or the amended disclosure letter to be delivered by the Company to
Unisource within three weeks from the date of the Merger Agreement, are not to
its satisfaction, in accordance with the completion of the due diligence
provisions of the Merger Agreement. In the event the Merger Agreement is
terminated as described in this paragraph, the Merger Agreement shall forthwith
become void and of no effect with no liability on the part of any party to the
Merger Agreement, except with respect to certain specified provisions (including
the provisions as to confidentiality, and the provisions described below under
Fee and Expenses) which survive the termination. The termination of the Merger
Agreement in accordance with this paragraph does not release any party from any
liability for any willful breach by such party of the terms and provisions of
the Merger Agreement.
 
     Fees and Expenses.  The Merger Agreement provides that all costs and
expenses in connection with the Merger Agreement and the transaction
contemplated by the Merger Agreement shall be paid by the party incurring such
cost or expense, whether or not the Merger is consummated. Neither the Company
nor Chemed is paying a fee to an investment banker, broker or other entity in
connection with the Merger.
 
     Conduct of Business by the Company.  The Merger Agreement provides that the
Company and its subsidiaries will conduct their business in the ordinary course
consistent with past practice and use their best efforts to preserve intact
their business organizations and relationships with third parties and to keep
available
 
                                       15
<PAGE>   20
 
the services of their officers and employees. The Merger Agreement further
provides that, without limiting the generality of the foregoing, during the
period from the date of the Merger Agreement to the Effective Time of the
Merger, (1) the Company will not adopt or propose, or permit any subsidiary to
adopt or propose, any change in its certificate of incorporation, bylaws or
other constituent documents; (2) the Company will not, and will not permit any
subsidiary to, merge or consolidate with any other person or acquire a material
amount of assets of any other person; (3) the Company will not, and will not
permit any subsidiary to, sell, lease, license or otherwise dispose of any
material assets or property except (i) pursuant to existing contracts or
commitments and (ii) in the ordinary course consistent with past practice; (4)
the Company will not, and will not permit any subsidiary to, agree or commit to
do any of the foregoing; or (5) the Company will not, and will not permit any
subsidiary to (i) take or agree to commit to take any action that would make any
representation and warranty of the Company inaccurate in any respect at, or as
of any time prior to, the Effective Time or (ii) omit or agree or commit to omit
to take any action necessary to prevent any such representation or warranty from
being inaccurate in any respect at any such time.
 
     Board of Directors.  The Merger Agreement provides that from and after the
Effective Time, until successors are duly elected or appointed and qualified in
accordance with applicable law the directors of the Merger Sub at the Effective
Time shall be the directors of the Company as the Surviving Corporation.
 
                           SOURCE AND AMOUNT OF FUNDS
 
   
     The total amount of funds required to fund the Merger Consideration, to
cancel and pay for all employee stock options, to pay fees and expenses related
to the Merger and to assume or repay existing debt of the Company is estimated
to be approximately $163 million. Such funds will be obtained through an
existing credit agreement with Unisource's bank.

                          AGREEMENT AND PLAN OF MERGER
 
     AGREEMENT AND PLAN OF MERGER dated as of August 11, 1997 among NATIONAL
SANITARY SUPPLY COMPANY, a Delaware corporation (the "Company"), UNISOURCE
WORLDWIDE, INC., a Delaware corporation ("BUYER"), and TFBD, INC., a Delaware
corporation and a wholly owned subsidiary of Buyer ("MERGER SUBSIDIARY").
 
     WHEREAS, the Board of Directors of each of Buyer, the Company and Merger
Subsidiary have determined that it is advisable and in the best interests of
their respective stockholders to engage in the transactions contemplated hereby;
and
 
     WHEREAS, the Board of Directors of the Company has approved the merger (the
"MERGER") of the Merger Subsidiary with and into the Company in accordance with
the terms of this Agreement and the General Corporation Law of the State of
Delaware (the "DELAWARE LAW") and other applicable law; and
 
     WHEREAS, this Agreement and the Merger shall be approved by the
stockholders of the Company for purposes of Delaware Law at such time as the
Company is in receipt of written consents approving this Agreement and the
Merger executed by the holders of that number of shares of common stock, par
value $1.00 per share, of the Company (each, a "SHARE") representing the right
to cast a majority of the votes entitled to be cast at a meeting to consider the
Agreement and the Merger; and
 
     WHEREAS, Chemed Corporation, a Delaware corporation ("CHEMED"), owns in
excess of 80% of the issued and outstanding Shares and concurrently with the
execution of this Agreement is delivering its written consent approving this
Agreement and the Merger as permitted by the certificate of incorporation and
bylaws of the Company and Delaware Law; and
 
     WHEREAS, such consent constitutes the only action necessary by stockholders
of the Company required in order to authorize this Agreement and the Merger
under the Company's certificate of incorporation and bylaws and Delaware Law;
and
 
     WHEREAS, Chemed, as an inducement to Buyer and Merger Subsidiary to enter
into the transactions contemplated hereby, is contemporaneously herewith
entering into the Indemnity Agreement and the Tax Matters Agreement (each as
defined below);
 
     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein, the parties hereto agree as follows:
 
                                   ARTICLE 1
 
                                   THE MERGER
 
     SECTION 1.01. The Merger. (a) At the Effective Time (as defined below),
Merger Subsidiary shall be merged with and into the Company in accordance with
Delaware Law, whereupon the separate existence of Merger Subsidiary shall cease,
and the Company shall be the surviving corporation (the "SURVIVING
CORPORATION").
 
     (b) As soon as practicable after the later of (i) satisfaction or waiver of
all conditions to the Merger and (ii) the 20th calendar day after the Company
Information Statement (as defined below) is first sent or given to the
stockholders of the Company, the Company and Merger Subsidiary will file a
certificate of merger with the Secretary of State of the State of Delaware and
make all other filings or recordings required by Delaware Law in connection with
the Merger. The Merger shall become effective at such time as the certificate of
merger is duly filed with the Secretary of State of the State of Delaware or at
such later time as is specified in the certificate of merger (the "EFFECTIVE
TIME").
 
     (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises and be subject to all
of the restrictions, disabilities and duties of the Company and Merger
Subsidiary, all as provided under Delaware Law.
 
                                       A-1
<PAGE>   30
 
     SECTION 1.02. Conversion of Shares. At the Effective Time:
 
          (a) each Share held by the Company as treasury stock or owned by Buyer
     or any subsidiary of Buyer immediately prior to the Effective Time shall be
     canceled, and no payment shall be made with respect thereto;
 
          (b) each share of common stock of Merger Subsidiary outstanding
     immediately prior to the Effective Time shall be converted into and become
     one share of common stock of the Surviving Corporation with the same
     rights, powers and privileges as the shares so converted and shall
     constitute the only outstanding shares of capital stock of the Surviving
     Corporation; and
 
          (c) each Share outstanding immediately prior to the Effective Time
     shall, except as otherwise provided in Section 1.02(a) or as provided in
     Section 1.04 with respect to Shares as to which appraisal rights have been
     exercised, be converted into the right to receive $21.00 in cash, without
     interest (the "MERGER CONSIDERATION").
 
     SECTION 1.03. Surrender and Payment. (a) Prior to the Effective Time, Buyer
shall appoint an agent (the "EXCHANGE AGENT") for the purpose of exchanging
certificates representing Shares for the Merger Consideration. Buyer will make
available to the Exchange Agent, in such amounts as may be needed from time to
time, the Merger Consideration to be paid in respect of the Shares. Promptly
after the Effective Time, Buyer will send, or will cause the Exchange Agent to
send, to each holder of Shares at the Effective Time a letter of transmittal for
use in such exchange (which shall specify that the delivery shall be effected,
and risk of loss and title shall pass, only upon proper delivery of the
certificates representing Shares to the Exchange Agent).
 
     (b) Each holder of Shares that have been converted into a right to receive
the Merger Consideration, upon surrender to the Exchange Agent of a certificate
or certificates representing such Shares, together with a properly completed
letter of transmittal covering such Shares, will be entitled to receive the
Merger Consideration payable in respect of such Shares. From and after the
Effective Time, all shares which have been so converted shall no longer be
outstanding and shall automatically be canceled and retired and each such
certificate shall, after the Effective Time, represent for all purposes, only
the right to receive such Merger Consideration. From and after the Effective
Time, the holders of Shares outstanding immediately prior to the Effective Time
shall cease to have any rights with respect to such Shares except as otherwise
provided in this Agreement or by applicable law. All cash paid upon the
surrender of certificates in accordance with the terms of this Section 1.03
shall be deemed to have been paid in full satisfaction of all rights pertaining
to the Shares previously represented by such certificates.
 
     (c) If any portion of the Merger Consideration is to be paid to a Person
(as defined below) other than the registered holder of the Shares represented by
the certificate or certificates surrendered in exchange therefor, it shall be a
condition to such payment that the certificate or certificates so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the Person requesting such payment shall pay to the Exchange Agent any transfer
or other taxes required as a result of such payment to a Person other than the
registered holder of such Shares or establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not payable. For purposes of
this Agreement, "PERSON" means an individual, a corporation, a limited liability
company, a partnership, an association, a trust or any other entity or
organization, including a government or political subdivision or any agency or
instrumentality thereof.
 
     (d) After the Effective Time, the stock transfer books of the Company shall
be closed and there shall be no further registration of transfers of Shares. If,
after the Effective Time, certificates representing Shares are presented to the
Surviving Corporation, they shall be canceled and exchanged for the
consideration provided for, and in accordance with the procedures set forth, in
this Article 1.
 
     (e) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.03(a) that remains unclaimed by the holders of
Shares twelve months after the Effective Time shall be returned to Buyer, upon
demand, and any such holder who has not exchanged his Shares for the Merger
Consideration in accordance with this Section prior to that time shall
thereafter look only to Buyer for payment of the Merger Consideration in respect
of his Shares. Notwithstanding the foregoing, Buyer shall not
 
                                       A-2
<PAGE>   31
 
be liable to any holder of Shares for any amount paid to a public official
pursuant to applicable abandoned property laws. Any amounts remaining unclaimed
by holders of Shares two years after the Effective Time (or such earlier date
immediately prior to such time as such amounts would otherwise escheat to or
become property of any governmental entity) shall, to the extent permitted by
applicable law, become the property of Buyer free and clear of any claims or
interest of any Person previously entitled thereto.
 
     (f) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.03(a) to pay for Shares for which appraisal rights
have been perfected shall be returned to Buyer, upon demand.
 
     SECTION 1.04. Dissenting Shares. Notwithstanding Section 1.02, Shares
outstanding immediately prior to the Effective Time and held by a holder who has
not voted in favor of the Merger or consented thereto in writing and who has
demanded appraisal for such Shares in accordance with Delaware Law shall not be
converted into a right to receive the Merger Consideration, unless such holder
fails to perfect or withdraws or otherwise loses his right to appraisal. If
after the Effective Time such holder fails to perfect or withdraws or loses his
right to appraisal, such Shares shall be treated as if they had been converted
as of the Effective Time into a right to receive the Merger Consideration. The
Company shall give Buyer prompt written notice of any demands received by the
Company for appraisal of Shares, and Buyer shall have the right to participate
in all negotiations and proceedings with respect to such demands. The Company
shall not, except with the prior written consent of Buyer, make any payment with
respect to, or settle or offer to settle, any such demands.
 
     SECTION 1.05. Stock Options. (a) At or immediately prior to the Effective
Time, each outstanding employee stock option to purchase Shares granted under
any employee stock option or compensation plan or arrangement of the Company
shall be canceled, and each holder of any such option, whether or not then
vested or exercisable, shall be paid by the Company promptly after the Effective
Time for each such option an amount determined by multiplying (i) the excess, if
any, of the Merger Consideration over the applicable exercise price of such
option by (ii) the number of Shares such holder could have purchased (assuming
full vesting of all options) had such holder exercised such option in full
immediately prior to the Effective Time, less any taxes required to be withheld
by the Company with respect thereto.
 
     (b) Prior to the Effective Time, the Company shall (i) obtain any consents
from holders of options to purchase Shares granted under the Company's stock
option or compensation plans or arrangements and (ii) make any amendments to the
terms of such stock option or compensation plans or arrangements that, in the
case of either clauses 1.05(b)(i) or 1.05(b)(ii), are necessary to give effect
to the transactions contemplated by Section 1.05(a). Notwithstanding any other
provision of this Section, payment may be withheld in respect of any employee
stock option until necessary consents are obtained.
 
     SECTION 1.06. Lost Certificates. If any certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the holder
claiming such certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such holder of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
certificate the Merger Consideration to be paid in respect of the Shares
represented by such certificate as contemplated by this Article.
 
     SECTION 1.07. Adjustments. If at any time during the period between the
date of this Agreement and the Effective Time, any change in the outstanding
Shares shall occur, including by reason of any reclassification,
recapitalization, stock dividend, stock split or combination, exchange or
readjustment of Shares, or any stock dividend thereon with the record date
during such period, the price per share to be paid to holders of Shares in the
Merger shall be appropriately adjusted.

     SECTION 2.01. Certificate of Incorporation. The certificate of
incorporation of Merger Subsidiary in effect at the Effective Time shall be the
certificate of incorporation of the Surviving Corporation until amended in
accordance with applicable law, except that the name of the Surviving
Corporation shall be changed to "National Sanitary Supply Company".
 
     SECTION 2.02. Bylaws. The bylaws of Merger Subsidiary in effect at the
Effective Time shall be the bylaws of the Surviving Corporation until amended in
accordance with applicable law.
 
     SECTION 2.03. Directors and Officers. From and after the Effective Time,
until successors are duly elected or appointed and qualified in accordance with
applicable law, (a) the directors of Merger Subsidiary at the Effective Time
shall be the directors of the Surviving Corporation, and (b) the officers of the
Company at the Effective Time shall be the officers of the Surviving
Corporation.

State of Delaware, and has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted. The Company is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except for those jurisdictions where the
failure to be so qualified would not, individually or in the aggregate, have a
material adverse effect on the condition (financial or otherwise), business,
assets or results of operations of the Company and the Subsidiaries (as defined
below) taken as a whole (a "MATERIAL ADVERSE EFFECT"). The Company has
heretofore delivered to Buyer true and complete copies of the Company's
certificate of incorporation and bylaws as currently in effect.
 
     SECTION 3.02. Corporate Authorization. The execution, delivery and
performance by the Company of this Agreement and the consummation by the Company

     SECTION 3.04. Non-contravention. The execution, delivery and performance by

transactions contemplated hereby do not and will not (a) contravene or conflict
with the certificate of incorporation or bylaws of the Company, (b) assuming
compliance with the matters referred to in Section 3.03, contravene or conflict
with or constitute a violation of any provision of any law, regulation,
judgment, injunction, order or decree binding upon or applicable to the Company
or any Subsidiary, (c) constitute a default under or give rise to a right of
termination, cancellation or acceleration of any right or obligation of the

binding upon the Company or any Subsidiary or any license, franchise, permit or
other similar authorization held by the Company or any Subsidiary, or (d) result

and (c) no options or other rights to acquire from the Company, and no

jurisdiction of incorporation, has all corporate powers and all material
governmental licenses, authorizations, consents and approvals required to carry
on its business as now conducted and is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except for those jurisdictions where failure
to be so qualified would not, individually or in the aggregate, have a Material
Adverse Effect. For purposes of this Agreement, "SUBSIDIARY" means any
corporation or other entity of which securities or other ownership interests

     (b) All of the outstanding capital stock of, or other ownership interests
in, each Subsidiary, is owned by the Company, directly or indirectly, free and
clear of any Lien and free of any other limitation or restriction (including any
restriction on the right to vote, sell or otherwise dispose of such capital
stock or other ownership interests). There are no outstanding (i) securities of
the Company or any Subsidiary convertible into or exchangeable for shares of
capital stock or other voting securities or ownership interests in any
Subsidiary, and (ii) options or other rights to acquire from the Company or any
Subsidiary, and no other obligation of the Company or any Subsidiary to issue,
any capital stock, voting securities or other ownership interests in, or any
securities convertible into or exchangeable for any capital stock, voting
securities or ownership interests in, any Subsidiary (the items in clauses
3.06(b)(i) and 3.06(b)(ii) being referred to collectively as the "SUBSIDIARY
SECURITIES"). There are no outstanding obligations of the Company or any
Subsidiary to repurchase, redeem or otherwise acquire any outstanding Subsidiary
Securities.
 
     SECTION 3.07. SEC Filings. (a) The Company has delivered to Buyer (i) the
annual reports on Form 10-K for its fiscal years ended December 31, 1996, 1995
and 1994, (ii) the quarterly report of the Company on Form 10-Q for the fiscal

to meetings of, or actions taken without a meeting by, the stockholders of the
Company since December 31, 1996, and (iv) all of its other reports, statements,
schedules and registration statements filed with the Securities and Exchange
Commission (the "SEC") since December 31, 1994.
 
     (b) As of its filing date, each such report or statement filed pursuant to
the Exchange Act did not contain any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements made
therein, in the light of the circumstances under which they were made, not
misleading.
 
     (c) Each such registration statement, as amended or supplemented, if
applicable, filed pursuant to the Securities Act of 1933 as of the date such
statement or amendment became effective did not contain any
 
                                       A-5
<PAGE>   34
 
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading.
 
     SECTION 3.08. Financial Statements. The audited consolidated financial
statements and unaudited consolidated interim financial statements of the
Company included in its annual reports on Form 10-K and the quarterly report on
Form 10-Q referred to in Section 3.07 fairly present, in conformity with
generally accepted accounting principles applied on a consistent basis (except
as may be indicated in the notes thereto), the consolidated financial position
of the Company and its consolidated subsidiaries as of the dates thereof and
their consolidated results of operations and changes in financial position for
the periods then ended (subject to normal year-end adjustments in the case of
any unaudited interim financial statements). For purposes of this Agreement,
"BALANCE SHEET" means the consolidated balance sheet of the Company as of
December 31, 1996 set forth in the Company 10-K and "BALANCE SHEET DATE" means
December 31, 1996.
 
     SECTION 3.09. Disclosure Documents. (a) Each document required to be filed
by the Company with the SEC in connection with the transactions contemplated by
this Agreement (the "COMPANY DISCLOSURE DOCUMENTS"), including, without
limitation, the proxy or information statement of the Company (the "COMPANY
INFORMATION STATEMENT") to be filed with the SEC in connection with the Merger,
and any amendments or supplements thereto will, when filed, comply as to form in
all material respects with the applicable requirements of the Exchange Act.
 
     (b) At the time the Company Information Statement or any amendment or
supplement thereto is first mailed to stockholders of the Company, and at the
Effective Time, the Company Information Statement, as supplemented or amended,
if applicable, will not contain any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements made
therein, in the light of the circumstances under which they were made, not
misleading. At the time of the filing of any Company Disclosure Document other

thereof, such Company Disclosure Document will not contain any untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements made therein, in the light of the circumstances under which they
were made, not misleading. The representations and warranties contained in this
Section 3.09(b) will not apply to statements or omissions included in the
Company Disclosure Documents based upon information furnished to the Company in
writing by Buyer specifically for use therein.

consistent with past practice and there has not been:
 
          (a) any event, occurrence or development of a state of circumstances

     Adverse Effect;
 
          (b) any declaration, setting aside or payment of any dividend or other
     distribution with respect to any shares of capital stock of the Company, or

     the Company or any Subsidiary of any outstanding shares of capital stock or
     other securities of, or other ownership interests (including options,
     rights or warrants) in, the Company or any Subsidiary;
 
          (c) any amendment of any material term of any outstanding security of

     stock of the Company (other than in connection with outstanding options);

     Lien on any material asset other than in the ordinary course of business
     consistent with past practices;
 
          (f) any making of any loan, advance or capital contributions to or
     investment in any Person other than loans, advances or capital
     contributions to or investments in wholly-owned Subsidiaries made in the
     ordinary course of business consistent with past practices;
 
                                       A-6
<PAGE>   35
 
          (g) any damage, destruction or other casualty loss (whether or not

     any Subsidiary which, individually or in the aggregate, has had or would
     reasonably be expected to have a Material Adverse Effect;
 
          (h) any transaction or commitment made, or any contract or agreement

     business (including the acquisition or disposition of any assets) or any
     relinquishment by the Company or any Subsidiary of any contract or other
     right, in either case, material to the Company and the Subsidiaries taken
     as a whole, other than transactions and commitments in the ordinary course
     of business consistent with past practice and those contemplated by this
     Agreement;
 
          (i) any change in any method of accounting or accounting practice by

     Date, or any lockouts, strikes, slowdowns, work stoppages or threats
     thereof by or with respect to such employees.
 
     SECTION 3.11. No Undisclosed Material Liabilities. There are no liabilities
or obligations of the Company or any Subsidiary of any kind whatsoever, whether
accrued, contingent, absolute, determined, determinable or otherwise, and there
is no existing condition, situation or set of circumstances which could
reasonably be expected to result in such a liability or obligation, other than:
 
          (a) liabilities or obligations disclosed or provided for in the
     Balance Sheet;
 
          (b) liabilities or obligations incurred in the ordinary course of
     business consistent with past practice since the Balance Sheet Date, which
     in the aggregate are not material to the Company and the Subsidiaries,
     taken as a whole; and
 
          (c) liabilities or obligations under this Agreement.

Company threatened against or affecting, the Company or any Subsidiary or any of
their respective properties before any court or arbitrator or any governmental

plaintiff's demands, would reasonably be expected to have a Material Adverse
Effect or which in any manner challenges or seeks to prevent, enjoin, alter or
materially delay the Merger or any of the other transactions contemplated
hereby.
 
     SECTION 3.13. Taxes. Except as set forth in the Balance Sheet (including
the notes thereto) and except as would not, individually or in the aggregate,

                                       A-7

with any taxing authority by, or with respect to, the Company and its
Subsidiaries have been filed in accordance with all applicable laws, (ii) the
Company and its Subsidiaries have timely paid all taxes shown as due and payable

there is no action, suit, proceeding, audit, or claim with respect to tax

securities market" within the meaning of Section 897(c)(2) of the Code and the
final and temporary regulations thereunder.
 
     SECTION 3.14. ERISA. (a) Definitions. For purposes hereof the following
terms have the following meanings:
 
     "BENEFIT ARRANGEMENT" means any employment, severance or similar contract
or arrangement (whether or not written) providing for compensation, bonus,
profit-sharing, stock option, or other stock related rights or other forms of
incentive or deferred compensation, vacation benefits, insurance coverage
(including any self-insured arrangements), health or medical benefits,
disability benefits, worker's compensation, supplemental unemployment benefits,
workers' compensation, supplemental unemployment benefits, severance benefits
and postemployment or retirement benefits (including compensation, pension,
health, medical or life insurance or other benefits) that (i) is not an Employee
Plan (as defined below), (ii) is entered into, maintained, administered or
contributed to, as the case may be, by the Company or any of its Affiliates (as
defined below) and (iii) covers any employee or former employee of the Company
or any Subsidiary.
 
     "EMPLOYEE PLAN" means any "employee benefit plan", as defined in Section
3(3) of ERISA, that (i) is subject to any provision of ERISA, (ii) is
maintained, administered or contributed to by the Company or any of its
Affiliates and (iii) covers any employee or former employee of the Company or
any Subsidiary.
 
     "ERISA" means the Employee Retirement Income Security Act of 1974.
 
     "ERISA AFFILIATE" of any entity means any other entity which, together with
such entity, would be treated as a single employer under Section 414 of the
Code.
 
     "MULTIEMPLOYER PLAN" means each Employee Plan that is a multiemployer plan,
as defined in Section 3(37) of ERISA.
 
     "PBGC" means the Pension Benefit Guaranty Corporation.
 
     "TITLE IV PLAN" means an Employee Plan subject to Title IV of ERISA other
than any Multiemployer Plan.
 
     (b) The Company has provided, or will provide prior to the Effective Time,
Buyer with a list and copies of the Employee Plans (and, if applicable, related
trust agreements) and all amendments thereto and written interpretations thereof
together with the most recent annual report (Form 5500 including all required
Schedules thereto) and the most recent actuarial valuation report prepared in
connection with any Employee Plan. Such list identifies each Employee Plan which
is (i) a Multiemployer plan, (ii) a Title IV Plan or (iii) maintained in
connection with any trust described in Section 501(c)(9) of the Code. The
Company has
 
                                       A-8
<PAGE>   37
 
provided, or will provide prior to the Effective Time, Buyer with complete age,
salary, service and related data as of the most recent practicable date for all
employees and former employees covered under any Title IV Plan.
 
     (c) The fair market value of the assets of each Title IV Plan (excluding
for these purposes any accrued but unpaid contributions) exceeds the present
value of all benefits accrued under such Title IV Plan determined on a
termination basis using the assumptions established by the PBGC. There is no
unfunded liability of the Company or any Subsidiary in respect of any Employee
Plans or Benefit Arrangements described under Sections 4(b)(5) of ERISA or
401(a)(1) of the Code, as computed using reasonable actuarial assumptions and
determined as if all benefits under such plans are vested and payable.
 
     (d) No transaction prohibited by Section 406 of ERISA or Section 4975 of
the Code has occurred with respect to any employee benefit plan or arrangement
which is covered by Title I of ERISA, which transaction has or will cause the
Company or any of its Subsidiaries to incur any liability under ERISA, the Code
or otherwise, excluding transactions effected pursuant to and in compliance with
a statutory or administrative exemption. No "accumulated funding deficiency", as
defined in Section 412 of the Code, has been incurred with respect to any
Employee Plan subject to such Section 412, whether or not waived. No "reportable
event", within the meaning of Section 4043 of ERISA, other than a "reportable
event" that will not have a Material Adverse Effect, and no event described in
Section 4062 or 4063 of ERISA, has occurred in connection with any Employee
Plan. Neither the Company nor any ERISA Affiliate of the Company has (i) engaged
in, or is a successor or parent corporation to an entity that has engaged in, a
transaction described in Sections 4069 or 4212(c) of ERISA or (ii) incurred, or
reasonably expects to incur prior to the Effective Time, (A) any liability under
Title IV of ERISA arising in connection with the termination of, or a complete
or partial withdrawal from, any plan covered or previously covered by Title IV
of ERISA or (B) any liability under Section 4971 of the Code that in either case
could become a liability of the Company or any Subsidiary or Buyer or any of its
ERISA Affiliates after the Effective Time. No condition exists that (i) could
constitute grounds for termination by the PBGC of any employee benefit plan that
is subject to Title IV of ERISA that is maintained by the Company, any
Subsidiary or any of their ERISA Affiliates or (ii) presents a material risk of
complete or partial withdrawal from any multiemployer plan, as defined in
Section 3(37) of ERISA, which could result in the Company, any Subsidiary or
Buyer or any ERISA Affiliate of any of them incurring a withdrawal liability
within the meaning of Section 4201 of ERISA. The assets of the Company and all
of its Subsidiaries are not now, nor will they after the passage of time be,
subject to any lien imposed under Code Section 412(n) by reason of a failure of
the Company or any Subsidiary to make timely installments or other payments
required under Code Section 412. If a "complete withdrawal" by the Company and
all of its ERISA Affiliates were to occur as of the Effective Time with respect
to all Multiemployer Plans, none of the Company, any Subsidiary or any of their
ERISA Affiliates would incur any material withdrawal liability under Title IV of
ERISA.
 
     (e) Each Employee Plan that is intended to be qualified under Section
401(a) of the Code is so qualified and has been so qualified during the period
since its adoption; each trust created under any such Plan is exempt from tax
under Section 501(a) of the Code and has been so exempt since its creation. The
Company has provided, or will provide prior to the Effective Time, Buyer with
the most recent determination letter of the Internal Revenue Service relating to
each such Employee Plan. Each Employee Plan has been maintained in substantial
compliance with its terms and with the requirements prescribed by any and all
applicable statutes, orders, rules and regulations, including but not limited to
ERISA and the Code.
 
     (f) The Company has provided, or will provide prior to the Effective Time,
Buyer with a list and copies or descriptions of each Benefit Arrangement (and,
if applicable, related trust agreements) and all amendments thereto and written
interpretations thereof. Each Benefit Arrangement has been maintained in
substantial compliance with its terms and with the requirements prescribed by
any and all applicable statutes, orders, rules and regulations and has been
maintained in good standing with applicable regulatory authorities.
 
     (g) Neither the Company nor any Subsidiary has any current or projected
liability in respect of post-employment or post-retirement health or medical or
life insurance benefits for retired, former or current employees of the Company
or any Subsidiary, except as required to avoid excise tax under Section 4980B of
 
                                       A-9
<PAGE>   38
 
the Code. No condition exists that would prevent the Company or any Subsidiary
from amending or terminating any Employee Plan or Benefit Arrangement providing
health or medical benefits in respect of any active employee of the Company or
any Subsidiary other than limitations imposed under the terms of a collective
bargaining agreement.
 
     (h) All contributions and payments which have either become due and payable
or should be accrued under each Employee Plan and Benefit Arrangement,
determined in accordance with prior funding and accrual practices, will be
discharged and paid or accrued, respectively, on or prior to the Effective Time
in accordance with such practices. There has been no amendment to, written
interpretation of or announcement (whether or not written) by the Company or any
Subsidiary relating to, or change in employee participation or coverage under,
any Employee Plan or Benefit Arrangement that would increase materially the
expense of maintaining such Employee Plan or Benefit Arrangement above the level
of the expense incurred in respect thereof for the most recent fiscal year ended
prior to the date hereof.
 
     (i) There is no contract, plan or arrangement (written or otherwise)
covering any employee or former employee of the Company or any Subsidiary that,
individually or collectively, could give rise to the payment of any amount that
would not be deductible pursuant to the terms of Section 280G of the Code.
 
     (j) There has been no failure of a group health plan (as defined in Section
5000(b)(1) of the Code) to meet the requirements of Code Section 4980B(f) with
respect to a qualified beneficiary (as defined in Section 4980B(g)). Neither the
Company nor any of its Subsidiaries has contributed to a nonconforming group
health plan (as defined in Section 5000(c)) and no ERISA Affiliate of the
Company or any of its Subsidiaries has incurred a tax under Section 5000(a)
which is or could become a liability of the Company or any of its Subsidiaries.
 
     (k) No employee or former employee of the Company or any Subsidiary will
become entitled to any bonus, retirement, severance, job security or similar
benefit or enhanced such benefit (including acceleration of vesting or exercise
of an incentive award) solely as a result of the transactions contemplated
hereby, except as contemplated by this Agreement.
 
     SECTION 3.15. Compliance with Laws.  The Company and each of its
Subsidiaries is and has been in compliance with, and to the knowledge of the
Company is not under investigation with respect to and has not been threatened
to be charged with or given notice of any violation of, any applicable law,
rule, regulation, judgment, injunction, order or decree, except for matters that
have not had and could not reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect.
 
     SECTION 3.16. Finders' Fees.  There is no investment banker, broker, finder
or other intermediary which has been retained by or is authorized to act on
behalf, of the Company or any Subsidiary who might be entitled to any fee or
commission from Buyer or any of its affiliates upon consummation of the
transactions contemplated by this Agreement.
 
     SECTION 3.17. Other Information.  None of the documents or information
delivered to Buyer in connection with the transactions contemplated by this
Agreement contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained therein not
misleading. The financial projections relating to the Company and the
Subsidiaries delivered to Buyer constitute the Company's best estimate of the
information purported to be shown therein and the Company is not aware of any
fact or information that would lead it to believe that such projections are
incorrect or misleading in any material respect.
 
     SECTION 3.18. Environmental Matters.  (a) Definitions. For purposes hereof
the following terms have the following meanings:
 
     "ENVIRONMENTAL LAWS" means any federal, state, local or foreign law
(including, without limitation, common law), treaty, judicial decision,
regulation, rule, judgment, order, decree, injunction, permit or governmental
restriction or requirement or any agreement with any governmental authority or
other third party, relating to human health and safety, the environment or to
pollutants, contaminants, wastes or
 
                                      A-10

     citation, summons or order has been received, no complaint has been filed,
     no penalty has been assessed, and no investigation, action, claim, suit,
     proceeding or review (or any basis therefor) is pending or, to the
     knowledge of the Company or any Subsidiary, is threatened by any
     governmental entity or other Person with respect to any matters relating to
     the Company or any Subsidiary and relating to or arising out of any
     Environmental Law which, individually or in the aggregate, could reasonably
     be expected to result in a Material Adverse Effect;
 
          (ii) The Company is in compliance with all Environmental Laws and has
     been and is in compliance with all Environmental Permits, except where any
     noncompliance or failure to receive Environmental Permits could not
     reasonably be expected to result in a Material Adverse Effect; and
 
          (iii) there are no liabilities of or relating to the Company or any
     Subsidiary of any kind whatsoever, whether accrued, contingent, absolute,
     determined, determinable or otherwise arising under or relating to any
     Environmental Law that have had or may reasonably be expected to have a
     Material Adverse Effect, and there are no facts, conditions, situations or
     set of circumstances which could reasonably be expected to result in or be
     the basis for any such liability.
 
     (c) There has been no environmental investigation, study, audit, test,
review or other analysis conducted of which the Company has knowledge in
relation to the current or prior business of the Company or any Subsidiary or
any property or facility now or previously owned or leased by the Company or any
Subsidiary which has not been delivered to Buyer at least five days prior to the
Effective Time.
 
     (d) Neither the Company nor any Subsidiary owns, leases or operates or has
owned, leased or operated any real property, or conducts or has conducted any
operations, in New Jersey or Connecticut.
 
     (e) For purposes of this Section, the terms "COMPANY" and "SUBSIDIARY"
shall include any entity which is, in whole or in part, a predecessor of the
Company or any Subsidiary.

series of capital stock of the Company necessary to approve the Merger is the
affirmative vote of the holders of a majority of the outstanding Shares.
 
     SECTION 3.20. Anti-Takeover Plan; State Takeover Statutes.  Neither the
Company nor any Subsidiary has in effect any plan, scheme, device or
arrangement, commonly or colloquially known as a "poison pill" or
"anti-takeover" plan or any similar plan, scheme, device or arrangement. The
Board of Directors of the Company has approved the Merger and this Agreement.
Except for Section 203 of Delaware Law, no state takeover statute or similar
statute or regulation applies or purports to apply to the Merger, this Agreement
or any of the transactions contemplated by this Agreement.
 
     SECTION 3.21. Intercompany Accounts.  Section 3.21 of the Disclosure Letter
contains a complete list of all intercompany balances as of the June 30, 1997
between Chemed and its Affiliates, on the one hand, and the Company and the
Subsidiaries, on the other hand. Since June 30, 1997 there has not been any
accrual of liability by the Company or any Subsidiary to Chemed or any of its
Affiliates or other transaction between the Company or any Subsidiary and Chemed

          (xi) any other agreement, commitment, arrangement or plan not made in

As used herein, the term "AFFILIATE" means, with respect to any Person, any
other Person directly or indirectly controlling, controlled by or under common
control with such Person.
 
     (b) Each agreement, contract, plan, lease, arrangement or commitment
disclosed in any Section of the Disclosure Letter or required to be disclosed
pursuant to this Section is a valid and binding agreement of the Company or a
Subsidiary, as the case may be, and is in full force and effect, and none of the
Company, any Subsidiary or, to the knowledge of the Company, any other party
thereto is in default or breach in any material respect under the terms of any
such agreement, contract, plan, lease, arrangement or commitment, and, to the
knowledge of the Company, no event or circumstance has occurred that, with
notice or lapse of time or both, would constitute any event of default

lease, arrangement or commitment have been delivered to Buyer.
 
     SECTION 3.23. Properties.  (a) The Company and the Subsidiaries have good
and marketable, indefeasible, fee simple title to, or in the case of leased

or acquired after the Balance Sheet Date, except for properties and assets sold
since the Balance Sheet Date in the
 
                                      A-12
<PAGE>   41
 
ordinary course of business consistent with past practices. None of such
property or assets is subject to any Lien, except:
 
          (i) Liens disclosed on the Balance Sheet;
 
          (ii) Liens for taxes not yet due or being contested in good faith (and
     for which adequate accruals or reserves have been established on the
     Balance Sheet); or
 
          (iii) Liens which do not materially detract from the value or
     materially interfere with any present or intended use of such property or
     assets.
 
     (b) There are no developments affecting any such property or assets pending
or, to the knowledge of the Company threatened, which might materially detract
from the value, materially interfere with any present or intended use or
materially adversely affect the marketability of any such property or assets.
 
     (c) The plants, buildings, structures and equipment owned by the Company or
any Subsidiary have no material defects, are in good operating condition and
repair and have been reasonably maintained consistent with standards generally
followed in the industry (giving due account to the age and length of use of
same, ordinary wear and tear excepted), are adequate and suitable for their
present and intended uses and, in the case of plants, buildings and other
structures (including, without limitation, the roofs thereof), are structurally
sound.
 
     (d) The plants, buildings and structures owned by the Company or any
Subsidiary currently have access to (i) public roads or valid easements over
private streets or private property for such ingress to and egress from all such
plants, buildings and structures and (ii) water supply, storm and sanitary sewer
facilities, telephone, gas and electrical connections, fire protection, drainage
and other public utilities, in each case as is necessary for the conduct of the
businesses of the Company or any Subsidiary as heretofore conducted. None of the
structures on any such owned or leased real property encroaches upon real
property of another Person, and no structure of any other Person substantially
encroaches upon any of such owned or leased real property.
 
     (e) Such real property, and its continued use, occupancy and operation as
currently used, occupied and operated, does not constitute a nonconforming use
under all applicable building, zoning, subdivision and other land use and
similar laws, regulations and ordinances.
 
     (f) The property and assets owned or leased by the Company or any
Subsidiary constitute all of the property and assets used or held for use in
connection with the businesses of the Company or any Subsidiary and are adequate
to conduct such businesses as currently conducted.
 
     SECTION 3.24. Products.  Each of the products produced or sold by the
Company or any Subsidiary is, and at all times up to and including the sale
thereof has been, (i) in compliance in all material respects with all applicable
federal, state, local and foreign laws and regulations and (ii) fit for the
ordinary purposes for which it is intended to be used and conforms in all
material respects to any promises or affirmations of fact made on the container

                                   ARTICLE 3
 
                           PURCHASE PRICE ADJUSTMENT
 
     SECTION 3.01. Closing Balance Sheet. (a) As promptly as practicable, but no
later than 90 days after the Effective Time, Chemed will cause a closing balance
sheet (the "Closing Balance Sheet") to be prepared and delivered to Buyer and a
certificate based on such Closing Balance Sheet setting forth Chemed's
calculation of total stockholders' equity as of the close of business on the day
of the Effective Time ("CLOSING STOCKHOLDERS' EQUITY"). The Closing Balance
Sheet shall (i) fairly present the consolidated financial position of the
Company as at the close of business on the day of the Effective Time in
accordance with United States generally accepted accounting principles ("GAAP")
applied on a basis consistent with those used in the preparation of the
Company's annual report on Form 10-K for the fiscal year ended December 31, 1996
(the "COMPANY 10- K"), (ii) include line items substantially consistent with
those in the Company 10- K, and (iii) be prepared in accordance with accounting
policies and practices consistent with those used in the preparation of the
Company 10-K, it being understood that neither the Closing Balance Sheet nor
Closing Stockholders' Equity shall be adjusted to reflect the cancelation of the
employee stock options referenced in Section 1.05 of the Merger Agreement.
 
     (b) If Buyer disagrees with Chemed's calculation of Closing Stockholders'
Equity delivered pursuant to Section 3.01(a), Buyer may, within 60 days after
delivery of the documents referred to in Section 3.01(a), deliver a notice to
Chemed disagreeing with such calculation and setting forth Buyer's calculation
of such amount. Any such notice of disagreement shall specify those items or
amounts as to which Buyer disagrees, and Buyer shall be deemed to have agreed
with all other items and amounts contained in the Closing Balance Sheet and the
calculation of Closing Stockholders' Equity delivered pursuant to Section
3.01(a).
<PAGE>   56
 
     (c) If a notice of disagreement shall be duly delivered pursuant to Section
3.01(b), Buyer and Chemed shall, during the 15 days following such delivery, use
their best efforts to reach agreement on the disputed items or amounts in order
to determine, as may be required, the amount of Closing Stockholders' Equity,
which amount shall not be less than the amount thereof shown in Buyer's
calculations delivered pursuant to Section 3.01(b) nor more than the amount
thereof shown in Chemed's calculation delivered pursuant to Section 3.01(a). If
during such period, Buyer and Chemed are unable to reach such agreement, they
shall promptly thereafter cause a firm of nationally recognized accountants
chosen and mutually accepted by both parties (the "ACCOUNTING REFEREE") promptly
to review this Agreement and the disputed items or amounts for the purpose of
calculating Closing Stockholders' Equity. In making such calculation, the
Accounting Referee shall consider only those items or amounts in the Closing
Balance Sheet or Chemed's calculation of Closing Stockholders' Equity as to
which Buyer has disagreed. The Accounting Referee shall deliver to Chemed and
Buyer, as promptly as practicable, a report setting forth such calculation. Such
report shall be final and binding upon the parties thereto. The cost of such
review and report shall be borne equally by the parties.
 
     (d) Buyer and Chemed agree that they will, and agree to cause their
respective independent accountants to, cooperate and assist in Buyer's review of
the Closing Balance Sheet and Chemed's calculation of Closing Stockholders'
Equity delivered pursuant to Section 3.01(a) and generally in the procedures and
reviews referred to in this Section 3.01(b) and (c), including without
limitation, the making available to the extent necessary of books, records, work
papers and personnel.
 
     (e) If the Closing Stockholders' Equity on the Closing Balance Sheet is
less than the amount shown as total stockholders' equity in the March 31 10-Q,
Chemed hereby agrees to promptly pay Buyer, on a dollar-for-dollar basis, an
amount equal to such deficiency.
 
                                   ARTICLE 4
 
                           SURVIVAL; INDEMNIFICATION
 
     SECTION 4.01. Survival. The Merger Agreement Representations shall each
survive until the expiration of their respective periods set forth in the Merger
Agreement. All of the other representations, warranties, covenants and
agreements set forth herein shall survive until the expiration of the last
surviving Merger Agreement Representation. Notwithstanding the preceding
sentence, any covenant, agreement, representation or warranty in respect of
which indemnity may be sought under this Agreement shall survive the time at
which it would otherwise terminate pursuant to the preceding sentence, if notice
of the inaccuracy or breach thereof giving rise to such right of indemnity shall
have been given to the party against whom such indemnity may be sought, in
accordance with the provisions of Section 4.02, prior to such time.
 
     SECTION 4.02. Indemnification. (a) Subject to the limitations set forth in
Section 4.04 hereof, Chemed hereby indemnifies Buyer and its Affiliates
(including, after the Effective Time, without duplication, the Surviving
Corporation and any Subsidiary) (the "BUYER INDEMNITEES") from and against and
agrees to hold the Buyer Indemnitees harmless from any and all damage, loss,
liability and expense (including without limitation reasonable expenses of
investigation and reasonable attorneys' fees and out-of-pocket expenses in
connection with any action, suit or proceeding, regardless of whether Chemed or
any other present or future stockholder of the Company is a party thereto)
("DAMAGES") incurred or suffered by the Buyer Indemnitees arising out of (i) any
misrepresentation or breach of warranty, covenant or agreement made or to be
performed by Chemed pursuant to this Agreement (including the Merger Agreement
Representations), or (ii) any claim by any present or future stockholder of the
Company or Chemed arising out of or in connection with the Merger.
 
     (b) Notwithstanding anything to the contrary in this Agreement and in
addition to the indemnification provision set forth in Section 4.02(a), but
subject to the limitations set forth in Section 4.04 hereof, Chemed hereby
indemnifies the Buyer Indemnitees from and against and agrees to hold each of
the Buyer Indemnitees harmless from any and all Damages (including without
limitation reasonable out-of-pocket expenses of investigation by engineers,
environmental consultants and similar technical personnel) of the Buyer Indemni-
<PAGE>   57
 
tees arising out of any breach of any representation or warranty made by the
Company in Section 3.18 of the Merger Agreement.
 
     SECTION 4.03. Indemnification Procedures.
 
     (a) For the purposes of this Section, the term "INDEMNITEE" shall refer to
the party entitled, or claiming to be entitled, to be indemnified pursuant to
the provisions of Section 4.02(a) or 4.02(b). The term "INDEMNITOR" shall refer
to the Person having the obligation to indemnify pursuant to such provisions.
 
     (b) An Indemnitee shall promptly give the Indemnitor written notice of any
matter which an Indemnitee has determined has given or could give rise to a
right of indemnification under this Agreement, stating the amount of the
Damages, if known, and method of computation thereof, all with reasonable
particularity and containing a reference to the provisions of this Agreement in
respect of which such right of indemnification is claimed or arises. The failure
by any Indemnitee so to notify the Indemnitor shall not relieve the Indemnitor
from any liability which it may have to such Indemnitee under Section 4.02
except to the extent that the Indemnitor demonstrates that it has been
materially prejudiced by such failure and then only to the extent of such
prejudice; provided that such notice is sent to the Indemnitor within the period
during which indemnification is available, as set forth in Section 4.01 hereof.
If an Indemnitee shall receive notice of any claim by a third party which is or
may be subject to indemnification (a "THIRD PARTY CLAIM"), the Indemnitee shall
give the Indemnitor prompt written notice of such Third Party Claim. The
Indemnitee shall have the right to defend, at the sole cost and expense of the
Indemnitor any Third Party Claim by all appropriate proceedings, which
proceedings shall be prosecuted diligently by the Indemnitee to a final
conclusion or settled (subject to this Section 4.03) at the discretion of the
Indemnitee. The Indemnitee shall permit the Indemnitor, at its option, to
participate in the defense of such Third Party Claim by counsel of its own
choice and at its expense, it being understood that the Indemnitee shall control
such defense. The Indemnitor shall cooperate with the Indemnitee in the defense
of any Third Party Claim and make available to the Indemnitee, at the
Indemnitor's expense, all witnesses (on a mutually convenient basis), pertinent
records, materials and information in its possession or under its control
relating thereto as is reasonably required by the Indemnitee. In no event shall
the Indemnitee consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnitor (not to be withheld unreasonably). The indemnification required by
Section 4.02 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, as and when bills are received or
Damages are incurred.
 
     In the event an Indemnitee should have a claim against an Indemnitor under
Section 4.02 that does not involve a Third Party Claim, the Indemnitee shall
deliver notice of such claim with reasonable promptness to the Indemnitor. The
failure by an Indemnitee so to notify the Indemnitor shall not relieve the
Indemnitor from any liability which it may have to such Indemnitee under Section
4.02 except to the extent that the Indemnitor demonstrates that it has been
materially prejudiced by such failure and then only to the extent of such
prejudice; provided that such notice is sent to the Indemnitor within the period
during which indemnification is available, as set forth in Section 4.01 hereof.
If the Indemnitor does not notify the Indemnitee within a reasonable period
following its receipt of such notice that the Indemnitor disputes its liability
to the Indemnitee under Section 4.02 such claim specified by the Indemnitee in
such notice shall be conclusively deemed a liability of the Indemnitor under
Section 4.02, and the Indemnitor shall pay the amount of such liability to the
Indemnitee on demand or, in the case of any notice in which the amount of the
claim (or any portion thereof) is estimated, on such later date when the amount
of such claim (or such portion thereof) becomes finally determined. If the
Indemnitor has timely disputed its liability with respect to such claim, as
provided above, the Indemnitor and the Indemnitee shall proceed in good faith to
negotiate a resolution of such dispute and, if not resolved through
negotiations, such dispute shall be resolved by a mutually acceptable
arbitrator. Arbitration shall be conducted under and pursuant to the rules of
the American Arbitration Association.
 
     SECTION 4.04. Limitations on Indemnification. The obligations of Chemed set
forth in Section 4.02(a) and (b) shall be subject to the following limitations:
<PAGE>   58
 
     Chemed shall not be liable for any Damages under Section 4.02(a) or (b)
unless such Damages, together with the aggregate amount of all Damages incurred
by Buyer Indemnitees pursuant to Section 4.02(a) or (b) of this Agreement shall
exceed $750,000 and then only to the extent of such excess; provided that if the
aggregate amount of Damages incurred by Buyer Indemnitees pursuant to Section
4.02(a) or (b) hereof exceeds $3,250,000 Chemed shall be liable for all such
Damages from dollar one; and provided further, none of the foregoing
restrictions shall apply with respect to Damages caused by a breach of any of
the representations or warranties contained in Section 3.13 of the Merger
Agreement.
 
                                   ARTICLE 5
 
                               EMPLOYEE BENEFITS
 
     SECTION 5.01. Chemed's Employee Benefit Plans. Chemed shall retain all
obligations and liabilities under the Employee Plans and Benefit Arrangements
listed on Schedule 5.01 hereto. Except as expressly set forth herein, Chemed or
its designated Affiliate shall retain all liabilities and obligations in respect
of benefits accrued as of the Effective Time under the Employee Plans and
Benefit Arrangements listed on Schedule 5.01 hereto, and neither Buyer nor any
of its Affiliates shall have any liability with respect thereto.
 
                                   ARTICLE 6

Agreement, each of the parties hereto agrees to use its best efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate the transactions contemplated by this Agreement.
 
     SECTION 6.03. Notices. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by cable, telegram, telefax or telex, or by registered or certified
mail (postage prepaid, return receipt requested) to such party at its address as
set forth on the signature pages hereof.
 
     SECTION 6.04. Amendments; Termination. This Agreement may not be modified,
amended, altered or supplemented, except upon the execution and delivery of a
written agreement executed by the parties hereto. This Agreement shall terminate
upon termination of the Merger Agreement in accordance with its terms.
 
     SECTION 6.05. Successors and Assigns. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, provided that no party may assign, delegate
or otherwise transfer any of its rights or obligations under this Agreement
without the prior written consent of the other parties hereto.
 
     SECTION 6.06. Governing Law. This Agreement shall be construed in
accordance with and governed by the law of Delaware without giving effect to the
principles of conflicts of laws thereof.
 
     SECTION 6.07. Counterparts; Effectiveness. This Agreement may be signed in
any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become effective when each party hereto shall have received
counterparts hereof signed by all of the other parties hereto.

the Company, its Subsidiaries, Buyer or any Affiliate of Buyer to take any
action on the Closing Date, except as agreed in writing between the parties
(including, but not limited to, the distribution of any dividend or the

loss on the part of the Company or its Subsidiaries under this Agreement.
 
     2.2 CHEMED'S COVENANTS.  (a) Without the prior written consent of Buyer,
neither Chemed nor the Company, any Subsidiary of the Company or any Affiliate

Section 338(h)(10) Election. Such cooperation shall include, but not be limited
to, the following:
 
     (i) the treatment of the transaction as a sale of assets;
 
     (ii) the determination of the fair market value of the assets of the
          Company and each Subsidiary, and the calculation of the adjusted
          gross-up basis, within the meaning of Treasury Regulation Section
          1.338(b)-1;
 
     (iii) the allocation of the deemed purchase price among the acquired assets

prepared by Buyer as soon as possible thereafter. In all events, the Price
Allocation Schedule shall be finally prepared and agreed upon prior to March 15,
1998. Buyer and Chemed shall each pay one-half of the costs, fees and expenses
of the Accounting Referee. The Price Allocation Schedule shall be binding on the
parties hereto, and Chemed and Buyer agree to act in accordance with such
Schedule in the preparation and filing of any Return.

and other such Taxes and fees (including any penalties and interest) incurred in
connection with this Agreement (including any real property transfer Tax and any
similar Tax) shall be paid by Chemed when due, and Chemed will, at its own
expense, file all necessary Returns and other documentation with respect to all
such Taxes and fees, and, if required by applicable law, Buyer will, and will
cause its Affiliates to, join in the execution of any such Returns and other
documentation.

Company's Subsidiaries in Chemed's consolidated federal income Tax Return and,

unitary Tax Returns that include the Company or any of the Company's
Subsidiaries) that are required to be filed with respect to the Company or any
of its Subsidiaries for all Tax Periods that end on or before the Closing Date.
At least 15 days prior to the filing of any such Tax Return for any Tax Period

Subsidiaries).

                                  TAX SHARING
 
     3.1 TERMINATION OF EXISTING TAX SHARING AGREEMENTS.  (a) Effective as of
the date hereof, the Tax Sharing Agreements and any other tax sharing agreements
or arrangements to which the Company or any of its Subsidiaries is a party shall
be terminated. Beginning on the date hereof, neither the Company nor any of its
Subsidiaries shall have any further rights (except to the extent provided in
Section 3.1(c)) or liabilities thereunder. As of the date hereof, this Agreement
shall be the sole tax sharing agreement relating to the Company or any of its
Subsidiaries for all Pre-Closing Tax Periods.
 
     (b) Notwithstanding any provision in any Tax Sharing Agreement to the
contrary, neither the Company nor any of its Subsidiaries shall have any
liability under the Tax Sharing Agreements as a result of any election made
under Section 338 of the Code with respect to the Merger.
 
     (c) In the event that, as of the date hereof, Chemed owes any amount to the
Company under the Tax Sharing Agreement between the two parties, Chemed shall
promptly (and in all events prior to the Closing) pay such amount to the
Company.
 
     3.2 TAX SHARING.  (a) On the day after the Closing Date, the Company shall
pay Chemed $12,207,000 of the Section 338(h)(10) Tax. Chemed shall retain
liability for the remainder of the Section 338(h)(10) Tax.
 
     (b) Not later than six months after the Closing Date, Chemed shall deliver
to the Company and Buyer a schedule showing the amount of Tax to be reported on
the Chemed Group consolidated federal income Tax Return for 1997 that is
attributable to the Company and its Subsidiaries (in each case, a "Tax Amount").
Each such schedule (a "True-Up Schedule") shall include all supporting work
papers and an explanation of the basis on which each such Tax Amount was
computed. The Tax Amount set forth on each True-Up Schedule shall be calculated
as if Company were filing its own consolidated federal income Tax Return
including Company's Subsidiaries (with the Company as the common parent) for all
Pre-Closing Tax Periods; provided, however, that (i) income, deductions, credits
and losses shall be computed in a manner consistent with past practices, (ii)
there shall be excluded from such calculation (x) any income, gain, deduction,
deferred gain or recapture of deductions or credits against Tax resulting
directly or indirectly from the Section 338(h)(10) Election or as a consequence
of Section 338 as applied by any state or local or foreign jurisdiction and (y)
Taxes of the Company and its Subsidiaries that are attributable to the
restoration of any deferred gain or loss under Treasury Regulations Sections
1.1502-13 or -13T, the inclusion in income of any excess loss account under
Treasury Regulations Section 1.1502-19 and the restoration or inclusion of any
similar item under any other Tax law or regulation, as a result of Chemed's
disposition of Company's stock pursuant to the Merger Agreement, and (iii) the
applicable Tax rates shall be the appropriate statutory rates in effect during
the relevant Pre-Closing Tax Period. In no event shall the Tax Amount set forth
on either True-Up Schedule exceed the amount that would be payable had such
liability been calculated in accordance with Treasury Regulations Section
1.1552-1(a)(2), excluding any Section 338 Tax. Chemed and Buyer agree that the
True-Up Schedule for 1997 will be prepared on the basis of a closing of the
books of the Company and its Subsidiaries as of the end of the Closing Date (but
without regard to the effect of the Section 338(h)(10) Election), as adjusted to
reflect income shown on the Company's permanent records (including work papers)
pursuant to Treasury Regulations Section 1.1502-76(b)(2)(i). Chemed, the Company
and its Subsidiaries and Buyer shall cooperate with one another in developing
the information which Chemed needs in order to compile the True-Up Schedules.
 
     (c) Within 15 days after receiving a True-Up Schedule, Buyer will notify
Chemed of any disagreement with any element of the Tax Amount reflected therein,
whereupon Chemed and Buyer will use their best efforts promptly to resolve any
such disagreement. In the event that Buyer advises Chemed of any objections to
the True-Up Schedule, and Buyer and Chemed are unable to resolve any differences
with respect to the True-Up Schedule within 30 days after receipt by Buyer of
the True-Up Schedule, then the issues remaining unresolved shall be determined
as follows:
<PAGE>   65
 
     (i) Chemed and Buyer shall jointly retain Accounting Referee and, within 15
         days following retention of the Accounting Referee, Chemed and Buyer
         shall present or cause to be presented to the Accounting Referee the
         issue or issues that must be resolved with respect the True-Up
         Schedule.
 
     (ii) Chemed and Buyer shall use their best efforts to cause the Accounting
          Referee to render its decision as soon as is reasonably practicable
          including, without limitation, prompt compliance with all reasonable
          requests by the Accounting Referee for information, papers, books,
          records and the like. All decisions of the Accounting Referee with
          respect to the issues presented by the parties shall be final and
          binding on the parties hereto.
 
     (iii) Chemed and Buyer shall bear equally all fees, costs, disbursements
           and other expenses of the Accounting Referee associated with the
           performance of its functions.
 
     (iv) Within 10 days after a Tax Amount is agreed to by Chemed and Buyer or
          determined by the Accounting Referee, the Company shall pay to Chemed
          the excess of (A) such Tax Amount over (B) the portion of such Tax
          Amount that the Company has previously paid, including payments
          pursuant to Section 3.2(d) below; provided, however, that if the
          amount determined under clause (B) exceeds the amount determined under
          clause (A), Chemed shall (within such 10-day period) pay such excess
          to the Company. Any such payments, by either party, shall include
          interest from March 15, 1998 computed at the rate or rates specified
          in Section 5.4. With respect to each Tax Amount agreed on by Chemed
          and Buyer or determined by the Accounting Referee, the True-Up
          Schedule and/or Accounting Referee's determination on which such Tax
          Amount is based shall be binding on the parties hereto, and Chemed and
          Buyer agree to act in accordance with such True-Up Schedule and/or
          Accounting Referee's determination in the preparation and filing of
          any Tax Return.
 
     (d) From the date of this Agreement until the Closing Date, on each date on
which a quarterly payment of estimated federal income Tax is due, the Company
shall pay to Chemed an amount representing the portion of Chemed's liability for
estimated Tax on that date which is attributable to the Company and its
Subsidiaries, based on the projected taxable income of the Company and its
subsidiaries for the relevant Tax period. A similar calculation and payment
shall be made on, and with respect to, the first quarterly due date after the
Closing Date for the quarterly period or portion thereof occurring prior to the
Closing Date. All payments provided for in this Section 3.2(d) shall be
calculated jointly, consistent with prior methods of computation, by Chemed and
the Company and shall reflect, to the extent practicable, the actual operating
results (determined based on interim closing of the books) of the Company and
its includable Subsidiaries during the quarterly periods in question. Further,
such calculations shall be based, to the extent applicable, on the reporting
positions, practices and conventions that were used in reporting the federal
income Tax liability of the Company and its includable Subsidiaries in Chemed's
consolidated federal income Tax Returns for prior Tax periods.
 
     (e) True-Up Schedules shall be prepared, and the Company shall make
payments to Chemed, or Chemed shall make payments to the Company, as the case
may be, with respect to any Combined State Tax of Chemed Group for the 1997 Tax
period of such Group by applying the principles of Sections 3.2(b), (c), and
(d).
 
     (f) Except as specifically provided in this Agreement, the Company and its
Subsidiaries shall not make any payment to Chemed (or any other person or entity
other than a Taxing Authority) on account of Taxes at any time after the date
hereof.
 
     (g) Any payment to a party pursuant to Section 3.2(b), (c), (d) or (e)
shall be net of any amount for which such party is liable under Article 3 of the
Indemnity Agreement.
 
     3.3 TAX REFUNDS.  Chemed shall promptly pay or cause to be paid promptly to
the Company the amount of any Tax refund and interest thereon with respect to
the Company or any of its Subsidiaries upon receipt by Chemed or any of its
Affiliates (or any successor of Chemed or any of its Affiliates) of such refund
(and payment to the Company of the amount of such refund (and interest thereon)
shall in all events be made within 30 days of the receipt of such refund by, as
the case may be, Chemed or its Affiliate).
<PAGE>   66
 
                                   ARTICLE 4.
 
                           COOPERATION ON TAX MATTERS
 
     4.1 TAX RECORDS.  Chemed will cause the Company and each Subsidiary of the
Company to retain all books, records or other information that reflect (i) the
original tax cost, (ii) the adjusted tax basis of all assets (including but not
limited to all investment assets, all depreciable real or personal property, and
all amortizable and non-amortizable intangible assets), and a schedule of all
depreciation or amortization claimed on such assets. Buyer and Chemed agree to
furnish or cause to be furnished to each other, upon request, as promptly as
practicable, such information (including access to books and records) and
assistance relating to the Company as is reasonably necessary for the filing of
any Return, for the preparation for any audit, and for the prosecution or
defense of any claim, suit or proceeding relating to any proposed adjustment.
Buyer and the Company agree to retain or cause to be retained all books and
records pertinent to the Company and its Subsidiaries until the applicable
period for assessment under applicable law (giving effect to any and all
extensions or waivers) has expired, and to abide by or cause the abidance with
all record retention agreements entered into with any Taxing Authority. The
Company agrees to give Chemed reasonable notice prior to transferring,
discarding or destroying any such books and records relating to Tax matters and,
if Chemed so requests, the Company shall allow Chemed to take possession of such
books and records.
 
     4.2 TAX PROCEEDINGS.  Chemed and Buyer shall cooperate with each other in
the conduct of any audit or other proceedings involving the Company or any of
its Subsidiaries for any Tax purposes and each shall execute and deliver such
powers of attorney and other documents as are necessary to carry out the intent
of this Article 4.
 
     4.3 INFORMATION RETURNS.  Chemed and Buyer further agree, upon request, to
provide the other party with all information that either party may be required
to report pursuant to Section 6043 of the Code and all Treasury Regulations
promulgated thereunder.
 
                                   ARTICLE 5.
 
                           INDEMNITY; CONTEST RIGHTS
 
     5.1 TAX INDEMNIFICATION.  (a) Chemed hereby indemnifies Buyer and its
Affiliates, including the Company and its Affiliates from and after the Closing
Date, against and agrees to hold Buyer and its Affiliates harmless from any (w)
Tax of the Company or any Subsidiary of the Company related to the Tax
Indemnification Period, (x) Tax of the Company or a Subsidiary of the Company
resulting from a breach of the provisions of Section 2.2(a), (y) Section 338
Tax, and (z) liabilities, costs, expenses (including, without limitation,
reasonable expenses of investigation and attorney's fees and expenses), losses,
damages, assessments, settlements or judgments arising out of or incident to the
imposition, assessment or assertion of any Tax described in (w), (x) or (y),
including any liability as transferee (the sum of (w), (x), (y), and (z) being
referred to herein as a "Loss"); provided, that in the case of an audit or other
proceeding to which Section 5.2(a) applies, no expense or cost described in
Section 5.2(c) shall be treated as a Loss.
 
     For purposes of this Section 5.1(a), in the case of any Taxes that are
imposed on a periodic basis and are payable for a Tax period that includes (but
does not end on) the Closing Date, the portion of such Tax related to the
portion of such Tax period ending on and including the Closing Date shall (i) in
the case of any Taxes other than (x) gross receipts, premiums, sales or use
Taxes and (y) Taxes based upon or related to income, be deemed to be the amount
of such Tax for the entire Tax period multiplied by a fraction the numerator of
which is the number of days in the Tax period ending on and including the
Closing Date and the denominator of which is the number of days in the entire
Tax period, and (ii) in the case of (x) any Tax based upon or related to income
and (y) any gross receipts, premiums, sales or use Tax, be deemed equal to the
amount which would be payable if the relevant Tax period ended on and included
the Closing Date. All determinations necessary to give effect to the foregoing
allocations shall be made in a manner consistent with prior practice of the
Company and its Subsidiaries.
<PAGE>   67
 
     (b) Upon payment by Buyer or any of its Affiliates of any Loss, Chemed
shall discharge its obligation to indemnify the Buyer or its Affiliate, as the
case may be, against such Loss by paying to Buyer an amount equal to the amount
of such Loss.
 
     (c) Any payment pursuant to this Section 5.1 shall be made not later than
30 days after receipt by Chemed of written notice from Buyer stating that any
Loss has been paid by Buyer or an Affiliate of Buyer and the amount thereof and
of the indemnity payment requested.
 
     (d) Any claim of any Affiliate of the Buyer under this Section 5.1 may be
made and enforced by Buyer on behalf of such Affiliate.
 
     5.2 CONTEST PROVISIONS.  (a) Upon the receipt by, as the case may be, Buyer
or its Affiliates or any member of Chemed Group of written notice of a proposed
adjustment or addition to Tax which could reasonably be expected to increase the
liability for Taxes of (in the case of a notice received by Buyer or any of its
Affiliates) a member of Chemed Group or (in the case of a notice received by a
member of Chemed Group) Buyer or any of its Affiliates (an "Adjustment"), Buyer
or Chemed , as the case may be, shall promptly notify the other in writing of
the receipt of such notice. Chemed shall have the right to represent the
interests of the Buyer and its Affiliates in any Tax audit or administrative or
court proceeding relating, in whole or in part, to such Adjustment (other than
an audit or proceeding to which Section 5.2(b) applies) and to employ counsel of
its choice at its expense. Notwithstanding the foregoing, Chemed shall not be
entitled to settle or discontinue such audit or proceeding without either (i)
receiving Buyer's prior written consent or (ii) preserving the ability of Buyer
or any of its Affiliates to file a claim for refund of such Taxes. The
requirements of the preceding sentence need not be satisfied to the extent that
Chemed has fully indemnified Buyer and its Affiliates against the effects of any
such settlement or discontinuance, including any effects that could reasonably
expected to be taken into account in Post-Closing Tax Periods. Chemed shall in
good faith keep Buyer informed with respect to any audit or proceeding to which
this Section 5.2(a) applies and shall consult with Buyer upon Buyer's reasonable
request for such consultation from time to time with respect to such audit or
proceeding.
 
     (b) Buyer shall control any audit or other proceeding relating to (i) any
Return of the Company or any of its Subsidiaries for a Pre-Closing Tax Period
which the Company or such Subsidiary, as the case may be, did not file as part
of a consolidated, combined or unitary group for Tax purposes, or (ii) any
Post-Closing Tax Period. Notwithstanding the foregoing, Buyer shall not be
entitled to settle or discontinue such audit or proceeding relating, in whole or
in part, to an Adjustment for which a member of the Chemed Group would be liable
without either (i) receiving Chemed's prior written consent or (ii) preserving
the ability of any member of Chemed Group to file a claim for refund of such
Taxes. The requirements of the preceding sentence need not be satisfied to the
extent that Buyer has fully indemnified the members of Chemed Group against the
effects of any such settlement or discontinuance. Buyer shall in good faith keep
Chemed informed with respect to any audit or proceeding to which this Section
5.2(b) applies and shall consult with Chemed upon Chemed's reasonable request
for such consultation from time to time with respect to such audit or
proceeding.
 
     (c) Buyer and Chemed each shall bear its own costs and expenses with
respect to an audit or proceeding to which Section 5.2(a) or 5.2(b) applies,
except to the extent that Buyer's costs and expenses in a proceeding to which
Section 5.2(b) applies are covered by Section 5.1(a).
 
     5.4 INTEREST.  Any payment required to be made by Chemed, the Company or
any of the Company's Subsidiaries under Sections 3.2, 3.3 or 5.1 that is not
made when due shall bear interest at the rate per annum determined, from time to
time, under the provisions of Section 6621(a)(2) of the Code for each day until
paid.
 
                                   ARTICLE 6.
 
                                    SURVIVAL
 
     6.1 SURVIVAL.  The provisions of this Agreement shall survive for the full
period of all statutes of limitations (giving effect to any waiver, mitigation
or extension thereof).

     IN WITNESS WHEREOF the parties hereto have caused this Agreement to be duly

                                    ANNEX B
 
            SECTION 262 OF THE GENERAL CORPORATIONS LAW OF DELAWARE
 
     SECTION 262. Appraisal rights.
 
     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to Section 228
of this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a non-stock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a non-stock corporation; and
the words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Sections 251 (other than a merger effected pursuant to
Section 251(g) of this title), Sections 252, 254, 257, 258, 263 or 264 of this
title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record dated fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of Section 251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     Sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
        a. Shares of stock of the corporation surviving or resulting from such
           merger or consolidation, or depository receipts in respect thereof;
 
        b. Shares of stock of any other corporation, or depository receipts in
           respect thereof, which shares of stock or depository receipts at the
           effective date of the merger or consolidation will be either listed
           on a national securities exchange or designated as a national market
           system security on an interdealer quotation system by the National
           Association of Securities Dealers, Inc. or held of record by more
           than 2,000 holders;
 
        c. Cash in lieu of fractional shares or fractional depository receipts
           described in the foregoing subparagraphs a. and b. of this paragraph;
           or
 
        d. Any combination of the shares of stock, depository receipts and cash
           in lieu of fractional shares or fractional depository receipts
           described in the foregoing subparagraphs a., b. and c. of this
           paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under Section 253 of this title is not owned by
     the parent corporation immediately prior to the merger, appraisal rights
     shall be available for the shares of the subsidiary Delaware Corporation.
<PAGE>   70
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to Section
     228 or Section 253 of this title, each constituent corporation, either
     before the effective date of the merger or consolidation or within 10 days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date
<PAGE>   71
 
     is fixed and the notice is given prior to the effective date, the record
     date shall be the close of business on the day next preceding the day on
     which the notice is given.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by one or more publications at
least one week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as
<PAGE>   72
 
the Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and in the case of holders of
shares represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all of
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
