the Meeting we will respond to any questions you may have.

 PROXY STATEMENT FOR SPECIAL MEETING OF SHAREHOLDERS TO BE HELD SEPTEMBER 13,
                                     1995
 
                               ----------------
 
  This proxy statement and accompanying proxy, which are being mailed to
shareholders on or about August 11, 1995, are furnished in connection with the
solicitation of proxies on behalf of the Board of Directors of VWR Corporation
(the "Corporation" or "VWR") to be voted at a Special Meeting (the "Meeting")
of Shareholders of the Corporation to be held at 11:00 a.m., EDT, on September
13, 1995, at the offices of the Corporation, 1310 Goshen Parkway, West
Chester, Pennsylvania, for the purposes set forth in the accompanying Notice
of Special Meeting of Shareholders. Shareholders who execute proxies retain
the right to revoke them at any time before they are voted. The proxy of any
shareholder may be revoked at any time prior to its exercise by giving written
notice to the Secretary of the Corporation, by presenting a duly executed
proxy bearing a later date, or by voting in person at the Meeting; but mere
attendance by a shareholder at the Meeting will not revoke a proxy previously
granted.
 
  The cost of solicitation of proxies will be borne by the Corporation. In
addition to solicitation by mail, directors, officers, and employees of the
Corporation may solicit proxies. The Corporation has employed Corporate
Investor Communications, Inc. to assist in the solicitation of proxies for a
fee expected to be approximately $5,000 plus reasonable expenses. Solicitation
is being made by the use of the mails, but may also be made by telephone,
other means of telecommunication and personal interviews.
 
  The approval of the issuance and sale of the Corporation's Common Shares,
par value $1.00 per share (the "Common Shares"), to EM Laboratories,
Incorporated ("EML"), an affiliate of E. Merck, Darmstadt, Germany, requires
the affirmative vote of a majority of the votes cast by all shareholders
present in person or by proxy and voting at the Meeting, a quorum being
present. If a proxy is marked as "abstain" on such proposal, or if specific
instructions are given that no vote be cast on such proposal (a "specified
non-vote"), the Common Shares represented by such proxy will not be voted on
such proposal. Abstentions and specified non-votes will have no effect on the
vote for the issuance and sale of Common Shares to EML, although such shares
will be included for purposes of determining the presence of a quorum for the
conduct of the Meeting.
 
  As of the close of business on July 14, 1995, the record date for the
Meeting, there were outstanding an aggregate of 12,898,870 Common Shares. The
Common Shares are the only class of securities of the Corporation entitled to
be voted at the Meeting. Each Common Share is entitled to one vote. Only
shareholders of record on the books of the Corporation at the close of
business on July 14, 1995 will be entitled to notice of, and to vote at, the
Meeting.
 
  In the event that at the time any session of the Meeting is called to order
a quorum is not present in person or by proxy, the persons named as proxies
may vote those proxies which have been received to adjourn the Meeting to a
later date so as to permit the solicitation of additional proxies to
constitute a quorum. In the event that a quorum is present but votes
sufficient to adopt the proposal to approve the issuance and sale of Common
Shares to EML have not been received,
 
                                       1
<PAGE>
 
the persons named as proxies may propose one or more adjournments of the
Meeting to permit further solicitation of proxies with respect to such
proposal. Any such adjournment will require the affirmative vote of the
holders of a majority of the Common Shares present in person or by proxy at
the session of the Meeting to be adjourned. The persons named as proxies will
vote those proxies which they are entitled to vote in favor of any proposal to
adjourn the Meeting with respect to the voting on the proposal to approve the
issuance and sale of Common Shares to EML, and will vote those proxies
required to be voted against the proposal to approve the issuance and sale of
Common Shares to EML against any such adjournment. Notice of the time and
place of any such adjourned session of the Meeting will be given at the
Meeting and otherwise to the extent required by law or the Bylaws of the
Corporation.
 
  ALL PROXIES WILL BE VOTED IN ACCORDANCE WITH INDICATED INSTRUCTIONS. IF NO
INSTRUCTIONS ARE GIVEN ON THE PROPOSAL TO APPROVE THE ISSUANCE AND SALE OF
COMMON SHARES TO EML, THE PROXY WILL BE VOTED FOR SUCH PROPOSAL.
 
  Holders of 2,924,241 Common Shares, including EML and certain directors of
the Corporation, constituting approximately 22.7% of the outstanding Common
Shares entitled to be voted at the Meeting, have advised the Corporation that
they intend to vote FOR the issuance and sale of Common Shares to EML.

                  ISSUANCE OF ADDITIONAL COMMON SHARES TO EML
 
GENERAL
 
  On April 13, 1995, pursuant to an agreement with EM Industries,
Incorporated, EML's direct parent corporation ("EMI"), the Corporation issued
and sold to EML 1,818,181 Common Shares (the "April Shares"), and a warrant
(the "April Warrant") exercisable to purchase an additional 967,015 Common
Shares at $11.00 per share. EML paid the Corporation an aggregate of
approximately $20,000,000 for the April Shares and the April Warrant, and the
Corporation has used the proceeds to reduce its indebtedness. As a result of
its acquisition of the April Shares and the April Warrant, EML now
beneficially owns (including the Common Shares covered by the April Warrant
which has not yet been exercised) approximately 20% of the Corporation's
issued and outstanding Common Shares.
 
  In connection with the agreement to purchase the April Shares and the April
Warrant, EMI entered into a Standstill Agreement with the Corporation, dated
February 27, 1995 (the "Standstill Agreement"), pursuant to which EMI agreed
that it and its affiliates would not, subject to certain specified exceptions,
for a period of four years, increase its beneficial ownership of the
Corporation's Common Shares above 20.1% (the "Original Percentage Limitation")
without the prior consent of the Corporation. EML directly assumed those
restrictions at the time of its purchase of the April Shares and the April
Warrant.
 
  The Corporation is now seeking shareholder approval of the proposed issuance
to EML of Common Shares which the Corporation has agreed to issue to EML,
subject to such shareholder approval, under the terms of (i) a Common Share
and Debenture Purchase Agreement, dated May 24, 1995 (the "Securities Purchase
Agreement") between the Corporation and EMI, (ii) a Subordinated Debenture of
the Corporation in the principal amount of $135,000,000 (the "Debenture")
which will be purchased by EML under the terms of the Securities Purchase
Agreement, and (iii) the Standstill Agreement, as proposed to be amended under
the terms of the Securities Purchase Agreement. EMI has assigned its rights
under the Standstill Agreement, as well as its rights to acquire additional
Common Shares and the Debenture under the Securities Purchase Agreement, to
EML. The Securities Purchase Agreement, the Debenture and the Standstill
Agreement are sometimes collectively referred to herein as the "EML
Agreements" and the Common Shares to be issued to EML under the EML Agreements
are referred to herein as the "EML Shares." Based upon 12,898,870 issued and
outstanding Common Shares as of July 14, 1995 (the record date) and assuming
the exercise by EML of the April Warrant, the EML Agreements contemplate the
issuance and sale by the Corporation to EML of approximately 8,242,000 Common
Shares, plus such additional number of Common Shares as will enable EML to
maintain an ownership percentage equal to 49.89% of the issued and outstanding
Common Shares. The obligations of the Corporation under the Securities
Purchase Agreement are subject to the approval by the Corporation's
shareholders of the issuance of the EML Shares.
 
  Approval by the shareholders of the Corporation of the issuance of the EML
Shares is required under the regulations of the Nasdaq Stock Market (R) which
require approval of issuances which result in a "change in control" of an
issuer. While the provisions of the Standstill Agreement are inconsistent with
a conclusion that EML's acquisition of the EML Shares will result in a change
in control of the Corporation (e.g., restrictions on further acquisitions of
VWR's Common Shares by EML or its affiliates and limitations on EML's
representation on VWR's Board of Directors. See "Issuance of Additional Common
Shares to EML--Summary of the Standstill Agreement and the Standstill
Amendment."), the Nasdaq regulations nevertheless require shareholder approval
of such issuances because of the significant percentage of Common Shares which
will be owned by EML as a result of the EML Agreements. Shareholder approval
is not otherwise required under applicable law or the Articles of
Incorporation or Bylaws of the Corporation.
 
                                       6
<PAGE>
 
SALE PRICES FOR THE EML SHARES AND THE DEBENTURE
 
  Under the terms of the Securities Purchase Agreement, EML has agreed to
purchase 6,832,797 Common Shares (the "Purchase Shares") at a price of $12.44
per share and the Debenture at a price of $135,000,000. After giving effect to
the purchase of the Purchase Shares and the exercise of the April Warrant, EML
will own approximately 46% of the issued and outstanding Common Shares. Under
the terms of the Debenture, the Corporation is obligated to issue to EML, at a
price of $12.44 per share in lieu of cash interest, that number of Common
Shares (the "Debenture Shares") as will cause EML's beneficial ownership of
Common Shares to increase to 49.89% (the "Amended Percentage Limitation") of
the issued and outstanding Common Shares. Assuming the Corporation does not
issue any additional Common Shares to third parties prior to the completion of
the issuance of the Debenture Shares to EML, the Corporation will issue
approximately 1,409,000 Debenture Shares to EML. Under the Standstill
Agreement, as proposed to be amended by the Securities Purchase Agreement, in
the event the Corporation issues additional Common Shares to third parties in
a registered public offering or private placement, EML is entitled to purchase
from time to time that number of Common Shares (the "Standstill Shares") as
will enable it to maintain an ownership interest of Common Shares equal to the
Amended Percentage Limitation at the same price at which the Corporation
proposes to issue such additional Common Shares to third parties. The
consideration to be received by VWR for the issuance and sale of the EML
Shares and the Debenture was determined by negotiations between the parties
and approved by the Board of Directors of VWR, with EML's Board
representatives abstaining. On May 24, 1995, the last trading day prior to the
announcement of the execution of the Securities Purchase Agreement, the high
and low per share sales price of the Corporation's Common Shares, as reported
by the Nasdaq Stock Market, were $10.00 and $9.25, respectively.
 
USE OF PROCEEDS FROM THE ISSUANCE OF THE EML SHARES AND THE DEBENTURE
 
  Closing under the Securities Purchase Agreement, and EML's exercise of the
April Warrant, are to occur on or prior to closing of VWR's proposed
acquisition of the industrial distribution business of the Industrial and Life
Sciences Division of Baxter Healthcare Corporation, a Delaware corporation
("Baxter") and the industrial distribution business conducted by certain
Baxter affiliates (collectively, the "Industrial Distribution Business"). The
proceeds from the issuance and sale of the Purchase Shares and the Debenture
(approximately $220,000,000) and from EML's exercise of the April Warrant
(approximately $10,600,000) will be used to fund, in part, the $400,000,000 to
be paid by VWR at the closing of such acquisition.
 
  Baxter is a wholly-owned subsidiary of Baxter International Inc., a Delaware
corporation. Such acquisition of assets from Baxter pursuant to the Asset
Purchase Agreement dated as of May 24, 1995 between Baxter and VWR (the "Asset
Purchase Agreement") is referred to herein as the "Acquisition." See
"Description of the Acquisition of the Industrial Distribution Business of
Baxter Healthcare Corporation" for information regarding the Industrial
Distribution Business and the terms of the Acquisition.
 
REASONS FOR THE ISSUANCE OF ADDITIONAL SHARES TO EML
 
  The Board of Directors of the Corporation has had two interdependent
corporate strategies which resulted in its decision to enter into the
Securities Purchase Agreement. The first set of reasons relates to the
desirability of the Acquisition. The Acquisition is intended to enable the
Corporation to substantially increase its sales volume through the
Corporation's existing distribution infrastructure (facilities and systems)
while increasing its associated costs by a smaller percentage. For a more
complete description of the Board's reasons for entering into the Asset
Purchase Agreement to effect the Acquisition, as well as certain risks to the
Corporation inherent in the Acquisition, see "Description of the Acquisition
of the Industrial Distribution Business of Baxter Healthcare Corporation--
VWR's Reasons for the Acquisition" and "--Risks To VWR Associated with the
Acquisition."
 
                                       7
<PAGE>
 
  At the time of VWR's acquisition in Canada of the Canlab division of an
affiliate of Baxter in the summer of 1994, the Corporation conducted
exploratory talks with Baxter about the possibility of acquiring the
Industrial Distribution Business. In connection with those discussions, the
Corporation and Goldman, Sachs & Co. ("Goldman, Sachs") discussed with several
possible funding sources the issuance by the Corporation of equity to fund
such a transaction. Only limited preliminary interest was demonstrated by
these potential sources. The Corporation did not pursue such discussions
because at the time the exploratory acquisition talks were terminated by
Baxter.
 
  At approximately the beginning of 1995, VWR resumed discussions with Baxter
regarding the possible acquisition of the Industrial Distribution Business.
Having reached the conclusion that the Acquisition would be in the best
interests of the Corporation and its shareholders, the Board then was required
to determine an optimal method for funding the Acquisition. The Board
recognized that the Acquisition would involve a high degree of risk to
shareholders if funded by an unduly large amount of borrowings. The Board
concluded that an adequate equity element was necessary. Because of both the
timing constraints associated with the Acquisition and the Corporation's
experience in seeking equity capital in the fall of 1994, the Board concluded
that it would not be desirable or feasible to raise additional equity to fund
the Acquisition through a public offering of equity securities or a broadly-
based institutional private placement.
 
  EML is a wholly-owned subsidiary of EMI, which is, in turn, a wholly-owned
subsidiary of Merck AG, a Swiss corporation. Merck AG is controlled by Merck &
Cie. KG, a Swiss partnership, which is 97.81% owned by Merck KGaA, Darmstadt,
Germany, a limited liability company based on shares, the majority of which
are owned by E. Merck, Darmstadt, Germany. Merck KGaA, Darmstadt, Germany, has
succeeded to E. Merck, Darmstadt Germany's international business of
manufacturing and distributing pharmaceutical, laboratory and chemical
products. In 1994, E. Merck, Darmstadt, Germany achieved worldwide sales of
approximately $3.5 billion. (E. Merck, Darmstadt, Germany and its affiliates
are not affiliated with Merck & Co., the United States-based manufacturer and
world wide distributor of pharmaceutical and other products.)
 
  During the past two years, the Corporation has formed certain strategic
alliances with E. Merck, Darmstadt, Germany and its affiliates. For example,
on December 17, 1993, the Corporation and E. Merck, Darmstadt, Germany entered
into a joint venture agreement whereby the Corporation acquired 10% of the
outstanding capital stock of Bender & Hobein GmbH, a subsidiary of E. Merck,
Darmstadt, Germany and one of the largest distributors of scientific products
in Germany, and agreed to provide certain distribution assistance to Bender &
Hobein. In addition, in early 1993 the Corporation's Canadian subsidiary, VWR
Scientific of Canada Ltd., became the sole distributor of certain chemical
products manufactured by BDH, Inc., a wholly-owned subsidiary of Merck AG. On
February 27, 1995, the date on which the Corporation and EMI executed the
agreements relating to the April Shares and April Warrant, the Corporation and
EMI entered into a distribution agreement (the "EMI Distribution Agreement")
which provides for the distribution in the United States of certain products
manufactured by EMI and its affiliates. These alliances most recently
culminated in the Corporation's sale to EML in April, 1995, of the April
Shares and the April Warrant for a total purchase price of approximately
$20,000,000, the proceeds of which were used by the Corporation to reduce its
indebtedness and thereby strengthen its balance sheet.
 
  It was in the context of the Corporation's growing set of relationships with
affiliates of E. Merck, Darmstadt, Germany that the Board determined that a
logical source of funding for the Acquisition would be E. Merck, Darmstadt,
Germany and its affiliates and that, by effecting such funding in that manner,
the Corporation could effectively pursue its goal of greater sales and
infrastructure utilization while further strengthening its strategic alliances
with E. Merck, Darmstadt, Germany and its affiliates.
 
 
                                       8

  The Board of Directors considered in substantial detail at a number of
meetings both the desirability and proposed terms of the Acquisition and the
discussions with EMI and its affiliates concerning possible funding of a
substantial portion of the cost of the Acquisition by EMI and its affiliates.
The deliberations culminated at the Board's meeting on May 24, 1995, at which
time the Board received an opinion from Goldman, Sachs that the consideration
to be paid by the Corporation for the Industrial Distribution Business
pursuant to the Asset Purchase Agreement is fair to the Corporation (see
"Description of the Acquisition of the Industrial Distribution Business of
Baxter Healthcare Corporation--Opinion of Financial Advisor Relating to the
Acquisition") and an opinion of PNC Securities Corp that the consideration to
be paid by EML in connection with the issuance and sale of the EML Shares and
the Debenture to EML are fair to the Corporation and its shareholders not
affiliated with EML from a financial point of view (see "--Opinion of
Financial Advisor Relating to the Issuance and Sale of Purchase Shares and
Debenture").
 
  The Board of Directors concluded that the issuance and sale of the EML
Shares on the terms provided for in the EML Agreements and the use of the
proceeds from the issuance and sale of the Purchase Shares and the Debenture
to fund a portion of the Acquisition presented an effective linchpin between
the corporate strategies inherent in the Corporation's pursuit of the
Acquisition and the desire to further strengthen the Corporation's strategic
alliance with E. Merck, Darmstadt, Germany and its affiliates.
 
OPINION OF FINANCIAL ADVISOR RELATING TO THE ISSUANCE AND SALE OF THE EML
SHARES AND DEBENTURE
 
  PNC Securities Corp ("PNC Securities") has delivered to the Corporation's
Board of Directors its opinion that, in light of the perceived benefits of
consummating the Acquisition and the necessity of obtaining financing
therefor, the consideration to be received by the Corporation in connection
with the issuance and sale of the EML Shares and the Debenture is fair to the
Corporation and its shareholders not affiliated with EML from a financial
point of view. The full text of the opinion of PNC Securities dated May 24,
1995, which sets forth certain assumptions made, matters considered and
limitations on and the scope of the review undertaken, is attached as Exhibit
I to this Proxy Statement. PNC Securities received no instructions from VWR,
nor were any limitations imposed by VWR or its affiliates on the scope of the
investigation made or procedures followed in connection with its fairness
opinion. In arriving at its opinion, PNC Securities was not authorized to
solicit, and did not solicit, inquiries with respect to the placement of
Common Shares or subordinated debt of the Corporation with institutional
investors in order to finance in part the Acquisition. In the opinion of VWR's
management, since May 24, 1995, no events have occurred, and there has been no
significant change in any information available to PNC Securities which should
alter PNC Securities' opinion given as of such date. SHAREHOLDERS ARE URGED TO
READ THE PNC SECURITIES OPINION CAREFULLY AND IN ITS ENTIRETY. The opinion of
PNC Securities is directed only to the fairness of the consideration to be
paid by EML in connection with the issuance and sale of the EML Shares and the
Debenture and does not constitute a recommendation to any VWR shareholder of
the Corporation as to how such shareholder should vote, nor an opinion
regarding the fairness to the Corporation of the terms of the Acquisition.
(See "Description of the Acquisition of the Industrial Distribution Business
of Baxter Healthcare Corporation--Opinion of Financial Advisor Relating to the
Acquisition.") The summary of the opinion of PNC Securities as set forth in
this Proxy Statement is qualified in its entirety by reference to the full
text of such opinion.
 
  In arriving at its opinion, PNC Securities, among other things, (i) analyzed
certain publicly-available financial statements and other information of the
Corporation, including documentation relating to the purchase by EML of the
April Shares and April Warrant; (ii) analyzed certain internal financial
statements and other financial and operating data concerning the Corporation,
 
                                       9
<PAGE>
 
including certain pro forma financial data giving effect to the consummation
of the Acquisition and related financing, prepared by the management of the
Corporation; (iii) analyzed certain financial data projections prepared by the
management of the Corporation; (iv) discussed the past and current operations
and financial condition and the prospects of the Corporation with senior
management of the Corporation, including the strategic and operating benefits
anticipated by senior management to be derived from the Acquisition, the
issuance and sale of the EML Shares and the Debenture and the Corporation's
commercial arrangements with EML and discussed with senior management of the
Corporation prior efforts by the Corporation to placing equity securities; (v)
reviewed the historical stock prices and trading volume of the Common Shares;
(vi) visited the principal offices of the Corporation; (vii) compared the
financial performance and prospects of the Corporation with that of certain
other comparable publicly-traded companies and analyzed the market valuation
of such companies; (viii) compared certain financial terms contained in the
EML Shares and the Debenture to certain financial terms of other selected
transactions deemed relevant; (ix) reviewed the principal terms of the
Acquisition and the opinion of Goldman Sachs, the Corporation's financial
advisor, dated May 24, 1995 with respect to the fairness to the Corporation of
the consideration to be paid by the Corporation for the Industrial
Distribution Business as of the date of such opinion; (x) reviewed the terms
of the EML Agreements (including the Standstill Agreement, as proposed to be
amended by the Securities Purchase Agreement) and related agreements as agreed
between the Corporation and EML; and (xi) performed such other analyses as PNC
Securities deemed appropriate.
 
  PNC Securities' opinion was based solely on the consideration to be received
by the Corporation from the issuance and sale of the EML Shares and the
Debenture to EML pursuant to the Securities Purchase Agreement subject to the
standstill restrictions contained in the Standstill Agreement, as proposed to
be amended by the Securities Purchase Agreement, which limit the ability of
EML and its affiliates to acquire majority ownership of the Corporation or to
elect a majority of the Board of Directors, for an agreed period of time and
under the conditions set forth in the Standstill Agreement and, as proposed to
be amended by the Securities Purchase Agreement. In rendering its opinion, it
was PNC Securities' understanding, based upon discussions with senior
management of the Corporation and its review of the related documents, that
EML will not acquire control of the management and direction of the business
and affairs of the Corporation as a result of the issuance and sale of the EML
Shares, and therefore the opinion of PNC Securities did not address the
question whether the consideration to be paid by EML for the EML Shares and
the Debenture would be fair from a financial point of view if the transactions
with EML were to result in a change of control.
 
  Further, PNC Securities assumed that the consideration to be paid by the
Corporation in connection with the Acquisition is fair to the Corporation and
its shareholders from a financial point of view. PNC Securities also
considered the view of the Board of Directors and senior management of the
Corporation that the Acquisition represents a significant business opportunity
for the Corporation and that significant strategic and operational benefits
will be derived by consummating the Acquisition and the concurrent investment
and commercial arrangements with EML, and the view of management of the
Corporation that the issuance and sale of the EML Shares and the Debenture
represents the best source of the financing for the Acquisition available to
the Corporation at the time and that the purchase by EML of the Purchase
Shares and the Debenture will provide significant benefit to the Corporation
by its assistance in obtaining necessary bank financing to consummate the
Acquisition.
 
  In connection with its opinion, PNC Securities did not independently verify
any of the financial and other information that was provided to PNC Securities
by the Corporation or that was publicly available, and its opinion is
conditioned on the information being complete and accurate in all material
respects. In addition, PNC Securities did not make and has not been provided
with any evaluation or appraisal of any of the assets (contingent or
otherwise) of the
 
                                      10
<PAGE>
 
Corporation. With respect to the financial projections, including pro forma
financial data taking into account the Acquisition, PNC Securities assumed
that they had been reasonably prepared on bases reflecting the best then
available estimates and judgments of the Corporation's management as to the
future financial performance of the Corporation. PNC Securities did not make
any independent evaluation of the solvency of the Corporation and assumed
after giving effect to the Acquisition and related debt and equity financing,
including the issuance and sale of the Purchase Shares and the Debenture, that
(i) the Corporation will be able to pay its debts as they become due in the
usual course of business; (ii) the fair value of the Corporation's total
assets would not be less than the Corporation's total liabilities; and (iii)
the Corporation will not have unreasonably small capital with which to engage
in its business. PNC Securities' opinion was based on economic, monetary and
market conditions existing at the date thereof. Furthermore, PNC Securities
expressed no opinion as to the price or trading range at which the Common
Shares will trade or as to the Corporation's ability to access the capital
markets prior to or subsequent to the consummation of the issuance and sale of
the EML Shares and the Debenture or the Acquisition.
 
  PNC Securities is an affiliate of PNC Bank, National Association ("PNC
Bank"). PNC Bank, Bank of America National Trust and Savings Association and
CoreStates Bank, N.A. have delivered a commitment letter to the Corporation
under which, subject to the terms and conditions thereof, those banks have
committed to lend the Corporation up to an aggregate of $285,000,000 to
provide the balance of the funds necessary to effect the Acquisition and to
provide the Corporation with post-Acquisition working capital. (See
"Description of the Acquisition of the Industrial Distribution Business of
Baxter Healthcare Corporation--Description of Other Financing of the
Acquisition.")
 
  Pursuant to the engagement letter between the Corporation and PNC Securities
relating to its financial advisory services in connection with the issuance
and sale of the EML Shares and the Debenture, the Corporation paid a fee of
$300,000 to PNC Securities plus certain of its expenses and agreed to
indemnify PNC Securities against certain liabilities, including certain
liabilities under the federal securities laws. To date PNC Securities has not
received any reimbursement of out-of-pocket expenses. PNC Securities estimates
that its out-of-pocket expenses, including fees and expenses of its counsel,
amount to approximately $35,000.
 
SUMMARY OF THE SECURITIES PURCHASE AGREEMENT
 
  The Securities Purchase Agreement is attached as Exhibit II to this Proxy
Statement and is incorporated herein by reference.
 
  Issuance and Sale of Purchase Shares and Debenture. Subject to the terms and
conditions of the Securities Purchase Agreement, on the Closing Date (as
defined in such Agreement) the Corporation will issue and sell the Purchase
Shares and the Debenture to EML for an aggregate purchase price of
$220,000,000. As a result of such purchase and EML's exercise of the April
Warrant, EML will own approximately 46% of the issued and outstanding Common
Shares.
 
  The Debenture. The Debenture will be in the principal amount of $135,000,000
and will mature in a single installment on the tenth anniversary of the issue
date. The indebtedness evidenced by the Debenture will be subordinated to the
Corporation's obligations to its primary bank lending institutions. Interest
will be payable on the unpaid principal of the Debenture quarterly at 13% per
annum, but until such time as EML and its affiliates own 49.89% of the
aggregate number of issued and outstanding Common Shares, interest shall be
payable solely in Debenture Shares at a price of $12.44 per share. Thereafter
and until the second anniversary of the issuance of the Debenture, the payment
of any cash interest otherwise accruing will be deferred until maturity of the
Debenture.
 
 
                                      11
<PAGE>
 
  Beginning on the fifth anniversary of the issue date of the Debenture, the
Corporation will have the right to redeem all or any portion of the Debenture,
but only from internally generated cash flow.
 
  Closing Conditions. The obligations of the Corporation to sell, and EML to
purchase, the Purchase Shares and the Debenture are subject to the requirement
that the proceeds from the Purchase Shares and Debenture be used solely for
the consummation of the Acquisition and are further subject to the
satisfaction on or before the Closing Date of certain additional conditions,
including that: (i) the issuance of the EML Shares has been approved by the
Corporation's shareholders; (ii) the issuance of the EML Shares has been
approved by the Nasdaq Stock Market; (iii) the waiting period under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"),
shall have expired or have been terminated; (iv) the parties shall have
executed and delivered the Amendment (the "Standstill Amendment") to the
Standstill Agreement; and (v) such other conditions to closing customary to
transactions of this nature as set forth in further detail in the Securities
Purchase Agreement.
 
  In addition, the obligation of EML to purchase the Purchase Shares and the
Debenture is also subject to (i) an amendment of the EMI Distribution
Agreement on terms to be mutually agreed upon; (ii) EML's not becoming an
"Acquiring Person" (as defined in the Rights Agreement (the "Rights
Agreement") dated May 20, 1988 between the Corporation and The First Jersey
National Bank, as amended) upon the acquisition of the Purchase Shares,
Debenture and Debenture Shares; and (iii) the execution and delivery of an
employment agreement between the Corporation and its President and Chief
Executive Officer satisfactory in form and substance to EML.
 
  Certain Covenants. In the Securities Purchase Agreement, the Corporation has
agreed, among other things, to: (a) use all proceeds received from EML from
the sale of the Purchase Shares and the Debenture for the purpose of financing
the Acquisition; (b) conduct its business through the Closing Date in the
ordinary course and, to the extent consistent with such business, use all
reasonable efforts to preserve intact its present business organization, to
keep available the services of its present officers and employees, and to
preserve its relationships with its customers, suppliers and others having
business dealings with it; (c) refrain through the Closing Date from
declaring, setting aside or paying any non-ordinary dividend or other
distribution with respect to shares of its capital stock; (d) refrain through
the Closing Date from issuing or selling any shares of its capital stock; (e)
refrain through the Closing Date from amending its Articles of Incorporation
or Bylaws or the Rights Agreement; and (f) call the Meeting and use its best
efforts to obtain shareholder approval at the Meeting of the issuance by the
Corporation of the EML Shares.
 
  In the Securities Purchase Agreement, EML has agreed, among other things,
to: (a) refrain from acquiring any Common Shares (other than those obtained
upon its exercise of the April Warrant) prior to the Closing Date without the
consent of the Corporation; (b) vote the Common Shares held by it at the
Meeting in favor of the issuance and sale of the EML Shares; and (c) exercise
the April Warrant on or before the Closing Date.
 
SUMMARY OF THE STANDSTILL AGREEMENT AND THE STANDSTILL AMENDMENT
 
  The Standstill Agreement and the Standstill Amendment are attached as
Exhibits III and IV, respectively, to this Proxy Statement and are
incorporated herein by reference.
 
  Restrictions on the Acquisition of Additional Common Shares. The Standstill
Agreement currently restricts EML and its affiliates from acquiring or holding
more than the Original Percentage Limitation of the Common Shares for a four
year period ending April 13, 1999 (the "Standstill Period"), subject to
certain exceptions, as set forth in more detail in such Agreement.
 
                                      12
<PAGE>
 
For example, if an unaffiliated third party made a tender or exchange offer to
acquire Common Shares, EML may make a tender offer for up to an equivalent
number of Common Shares (subject to the right of VWR to subsequently
repurchase Common Shares from EML to reduce EML's percentage Common Share
ownership to the Amended Percentage Limitation). In addition, EML may purchase
additional Common Shares upon the approval of two-thirds of VWR's directors
who were not nominated or appointed by EML. On April 13, 1995, EMI assigned
its rights and delegated its obligations under the Standstill Agreement to EML
whereupon EMI and EML became jointly and severally liable for their respective
performance under such Agreement. Under the Standstill Amendment, the Original
Percentage Limitation would be increased to 49.89% (the "Amended Percentage
Limitation") upon the issuance and sale of the Purchase Shares.
 
  Under the Standstill Agreement, neither EMI, EML or any affiliate of either
of them could make any further acquisition of Common Shares of the Corporation
following the expiration of the Standstill Period, without the consent of the
Corporation, unless it was by means of a tender offer for all of the shares
made to all other shareholders and the holders of at least two-thirds of the
shares not owned by EML and its affiliates had accepted such offer. Under the
Standstill Amendment, this restriction would be changed to provide that the
terms of such tender offer first be approved by a majority of the directors of
the Corporation not affiliated with or designated by EML and thereafter be
accepted by the holders of at least a majority of the shares not owned by EML
and its affiliates.
 
  Restrictions on the Transfer of Common Shares. The Standstill Agreement
currently prohibits EML and its affiliates from transferring any of its Common
Shares during the Standstill Period except in certain limited circumstances,
including: (i) sales made pursuant to the exercise of registration rights
granted by the Corporation by such Agreement; (ii) sales made pursuant to Rule
144 under the Securities Act of 1933, as amended (the "Securities Act"); (iii)
private sales to third parties (including sales pursuant to tender and
exchange offers and private offerings); (iv) certain transfers to affiliates;
and (v) sales made in conjunction with a merger or consolidation in which the
Corporation is acquired or in conjunction with a sale of all or substantially
all of the Corporation's assets, provided that the Corporation's Board of
Directors had approved such merger, consolidation or sale. Sales of any Common
Shares made pursuant to sub-clauses (i), (ii) and (iii) above, however, are
subject to the Corporation's rights of first refusal to purchase all, but not
fewer than all, of such Common Shares.
 
  Certain Covenants. Pursuant to the Standstill Agreement, EML has made
certain negative covenants to the Corporation. In particular, EML has agreed
that during the Standstill Period it and its affiliates will not, without the
prior consent of a majority of the Corporation's directors which are not
affiliated with EML, (i) solicit proxies or become a participant in opposition
to the Corporation's Board of Directors; (ii) deposit its Common Shares into a
voting trust or subject EML to any voting agreement with any non-affiliate of
EML; (iii) join any group for the purpose of acquiring, holding or disposing
of Common Shares within the meaning of Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"); (iv) induce or attempt
to induce any other person to initiate a tender offer for any securities of
the Corporation or to effect any change of control of the Corporation, or take
any action for the purpose of convening a meeting of the Corporation's
shareholders; and (v) acquire any class of equity securities of any entity
which, prior to the time of acquisition of more than 1% of such class, is
publicly disclosed to be the beneficial owner of more than 5% of any class of
the Corporation's voting securities.
 
  Under the terms of the Standstill Agreement and Standstill Amendment, the
Corporation has agreed not to issue any security which provides the holder(s)
thereof with any extraordinary or special voting rights or any right to veto
any action of the Corporation.
 
  EML Board Representation. The Corporation's Board of Directors is classified
and currently consists of eleven members distributed among three classes. The
terms of office of three directors
 
                                      13
<PAGE>
 
expire in 1996 and four such terms expire in each of 1997 and 1998. In
connection with the issuance of the April Shares and April Warrant, the
Corporation's Board of Directors was increased from nine to its present size
of eleven and two designees of EML were elected to the Board (with terms
expiring in 1997 and 1998, respectively) to fill the vacancies created
thereby. Pursuant to the Standstill Amendment, upon consummation of the
purchase and sale of the Purchase Shares, the Corporation on EML's request
will take all requisite action, including, without limitation, increasing or
decreasing the size of the Board, to enable EML to maintain Board
representation (rounded down to the nearest whole number) which at all times
is commensurate with the actual proportion of Common Shares owned by it and
its affiliates. So long as EML and its affiliates own no more than the Amended
Percentage Limitation, less than half of the Corporation's Board will be
comprised of members nominated by EML and its affiliates. Pursuant to the
Standstill Agreement, however, there are certain circumstances under which EML
and its affiliates could be entitled to nominate a majority of the Board by
increasing its ownership of Common Shares above the Amended Percentage
Limitation, as described above in the paragraph captioned "Summary of the
Standstill Agreement and the Standstill Amendment--Restrictions on the
Acquisition of Additional Common Shares."
 
  Registration Rights. Under the terms of the Standstill Agreement, EML is
entitled to certain registration rights with respect to Common Shares
beneficially owned by it, including the EML Shares. Subject to certain
conditions and limitations, EML may, during any twelve month period, require
the Corporation to effect one registration of any of the Common Shares held by
EML and its affiliates for sale under the Securities Act. In addition, subject
to certain conditions and limitations, if the Corporation proposes to register
any of its Common Shares under the Securities Act, EML is entitled to notice
of, and to include Common Shares which it owns in, such registration.
 
REGULATORY APPROVALS
 
  The Corporation and EML have made all requisite filings under the HSR Act
and the applicable waiting period has been terminated.
 
GENERAL EFFECT UPON THE RIGHTS OF EXISTING SHAREHOLDERS
 
  Influence by EML. After the consummation of the issuance and sale of the
Purchase Shares, EML will have the opportunity to exercise a material degree
of influence over the Corporation's business and activities through its
ability to vote the Common Shares owned by it and to nominate to the
Corporation's Board pursuant to the provisions of the Standstill Agreement
persons who will constitute one less than a majority of the members of the
Board. EML will not, however, be involved in the day-to-day management of the
Corporation's business. The shareholders owning Common Shares immediately
prior to such issuance and sale will continue to own a majority of the
outstanding Common Shares immediately after such issuance and sale, and will
continue to be able to elect nominees to the Board of Directors who are not
designees of EML and who will constitute a majority of the Board of Directors
of the Corporation.
 
  Future Acquisition of the Corporation. Following EML's purchase of the
Purchase Shares and the Debenture Shares, there will be a substantially
decreased likelihood that any party other than EML and its affiliates would
make an offer to acquire all of the equity interests of the Corporation. This
is so in large measure because, as a practical matter, no entity could
thereafter acquire the Corporation without EML's approval.
 
  In addition to its substantial equity investment in the Corporation, EML and
its affiliates would have an advantage over others in any subsequent
acquisition of the Corporation by reason of the fact that in connection with
EML's purchase of the April Shares and April Warrant, the Board of Directors
of the Corporation (i) approved an amendment to the Rights Agreement which
 
                                      14
<PAGE>
 
has the effect of excluding the application of the Rights Agreement as to EML
and its affiliates (so long as they are not in default under the Standstill
Agreement) and (ii) approved EML as a "20% Shareholder" (as that term is
defined in the Corporation's Articles of Incorporation) prior to its becoming
such, thereby rendering inapplicable the super-majority voting provision under
Article VIII of the Corporation's Articles of Incorporation. Absent a similar
approval, under Article VIII of the Corporation's Articles of Incorporation,
any merger or sale of assets between the Corporation and the beneficial owner
of 20% or more of the Corporation's voting securities would require the
affirmative vote of (i) the holders of 80% of the voting securities, including
(ii) the holders of more than 50% of the outstanding voting securities not
held by the 20% holder; however, by reason of the prior action of the Board of
Directors of the Corporation, these provisions are no longer applicable to EML
and its affiliates.
 
  Cumulative Voting. The Corporation's Articles of Incorporation provide that
for as long as the Corporation has a shareholder which owns 40% or more of the
issued and outstanding Common Shares (a "40% Shareholder"), all shareholders
of the Corporation shall be entitled to cumulate votes in the election of
directors. In addition, during any such time that the Corporation has a 40%
Shareholder, one or more candidates for the Corporation's Board of Directors
may be nominated by a majority of the Corporation's directors not affiliated
with such 40% Shareholder or by any person who beneficially owns Common Shares
having a market value of at least $250,000. Upon the issuance and sale of the
Purchase Shares to EML and EML's agreed-upon exercise of the April Warrant,
EML will be a 40% Shareholder. Accordingly, cumulative voting in the election
of the Corporation's directors and the aforementioned nomination rights will
become effective upon the issuance and sale of the Purchase Shares to EML.
 
CERTAIN OFFICERS' AGREEMENTS
 
  VWR has agreements with six of its most senior officers, including its
President and Chief Executive Officer. Each agreement provides that such
officer will receive compensation for up to 24 months if his employment
terminates (voluntarily or involuntarily) for any reason, other than gross
misconduct, death, disability, or reaching age 65, within two years following
completion of the proposed transactions with EML. The compensation will be
paid at a rate equal to the officer's current salary and target bonus. The
compensation is subject to a minimum annual rate of not less than the
officer's average compensation for the preceding three calendar years, and is
subject to reduction if the aggregate present value of all payments would
exceed three times the officer's "annualized includable compensation," as
defined in Section 280G of the Internal Revenue Code, for the officer's most
recent five taxable years. The officer will also continue to have "employee"
status for the 24 month period and will be entitled to retain most employee
benefits and rights during this period.
 
  The agreement between VWR and its President and Chief Executive Officer is
to be replaced by the employment agreement referred to under "Issuance of
Additional Common Shares to EML--Summary of the Securities Purchase
Agreement--Closing Conditions."
 
  The estimated aggregate amounts currently payable if the officers (not
including its President and Chief Executive Officer) were to exercise their
individual rights following completion of VWR's transactions with EML
(assuming each officer receives payment for the maximum 24-month period) would
be approximately $2,000,000. The foregoing amount does not include the value
of any employee benefits which might be payable to an officer during the 24-
month period. VWR may cease payments in the event the officer breaches certain
non-competition or confidentiality covenants.

LITIGATION
 
  Litigation relating to the issuance of the EML Shares and the Debenture has
been commenced (in Delaware by a person who alleges he is a shareholder of
VWR) against VWR, VWR's President and Chief Executive Officer, seven members
of VWR's Board of Directors and EMI. In the complaint the plaintiff seeks to
have an action certified as a class action and, on behalf of all shareholders
of VWR (except those named as defendants), to enjoin VWR from consummating the
transactions contemplated by the EML Agreements, an award of class rescissory
and/or compensatory damages, an award of costs and disbursements (including
fees of attorneys and experts) and such other further relief as the court
might deem just and proper. In addition, the plaintiff, on behalf of the
shareholders, seeks an order that the Director defendants take appropriate
measures to maximize shareholder value, including, without limitation,
creating an active auction for VWR.
 
  The plaintiff alleges, among other things, that the consummation of the
transactions contemplated by the EML Agreements will transfer control of VWR
to EMI and because EMI will own nearly 50% of VWR, no third party will make a
bid for VWR. The plaintiff also alleges that the individual defendants have
participated in unfair dealing towards plaintiff and the other shareholders by
failing to implement procedures for maximization of shareholder value and
permitting the transfer of control of VWR at a value which fails to reflect
the long-term value of VWR's Common Shares, particularly in light of VWR's
future prospects upon consummation of the Acquisition.
 
  VWR believes that this suit is without merit and VWR, EMI and the individual
defendants intend to vigorously defend this action. As described in this Proxy
Statement, VWR's Board of Directors believes that the Standstill Agreement and
the Standstill Amendment will protect shareholder value following the
consummation of the transactions contemplated by the EML Agreements.
 
REQUIRED VOTE
 
  The approval of the issuance and sale of the EML Shares requires the
affirmative vote of a majority of the votes cast by all shareholders
(including, without limitation, EML) present in person or by proxy and voting
at the Meeting, a quorum being present. Pursuant to the Securities Purchase
Agreement, EML has agreed to vote all 1,818,181 Common Shares owned by it on
the record date in favor of the proposal to approve the issuance and sale of
the EML Shares.
 
             THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL
                  OF THE ISSUANCE AND SALE OF THE EML SHARES

   DESCRIPTION OF THE ACQUISITION OF THE INDUSTRIAL DISTRIBUTION BUSINESS OF
                         BAXTER HEALTHCARE CORPORATION
 
INTRODUCTION AND BACKGROUND
 
  The following information with respect to the Acquisition is being provided
by VWR pursuant to the rules and requirements of the Securities and Exchange
Commission. There is no requirement that the Acquisition itself be approved by
VWR's shareholders, and no such approval is being sought at the Meeting.
Shareholders should understand, however, that approval of VWR's issuance of
additional Common Shares to EML, as described above in this Proxy Statement,
will permit VWR to consummate a critical component of the financing required
for the Acquisition. If the shareholders of the Corporation approve such
issuance, then, subject to the satisfaction of the terms and conditions of the
Securities Purchase Agreement described above and of the Asset Purchase
Agreement described below, it is likely that the Acquisition will be
consummated; if such issuance is not approved by the shareholders, then the
Acquisition could not be consummated under its existing terms and it is
unlikely it would be consummated at all.
 
GENERAL DESCRIPTION OF THE ACQUISITION
 
  The Industrial Distribution Business is engaged in the business of
distributing general laboratory supplies and equipment, worldwide, to
customers such as analytical research and development laboratories,
educational institutions, environmental testing laboratories, clean room
facilities, medical device manufacturers, electronic and semiconductor
manufacturers, government research facilities and others. For more detailed
information about the Industrial Distribution Business, which information has
been furnished by Baxter, see "Information About the Industrial Distribution
Business." The Industrial Distribution Business does not include Baxter's
distribution of products, whether manufactured by it or by others, in Canada
and Japan or to customers of Baxter who purchase such products for use in the
care of human patients or for the diagnosis of disease or defect for the
purpose of caring for human patients.
 
  Pursuant to the terms and conditions of the Asset Purchase Agreement, VWR
has agreed to acquire substantially all of the Industrial Distribution
Business. At the closing under the Asset Purchase Agreement, VWR will purchase
designated assets from Baxter, including, but not limited to, a portion of the
domestic trade accounts receivable of the Industrial Distribution Business,
certain tangible personal property, rights and benefits under certain
contracts and certain rights in specified trademarks. VWR will also assume, as
and to the extent specified in the Asset Purchase Agreement, (i) certain
liabilities of Baxter for accrued vacation pay; (ii) post-closing liabilities
and obligations under the acquired contracts; (iii) certain liabilities and
obligations to Baxter employees working solely in the Industrial Distribution
Business; and (iv) all liabilities for warranty claims for products sold by
the Industrial Distribution Business. The cash purchase price payable at
closing under the Asset Purchase Agreement is $400,000,000, subject to a post-
closing adjustment on a dollar-for-dollar basis to the extent that the amount
obtained by subtracting the accrued vacation pay liabilities being assumed as
of the date of closing, from the sum of trade accounts receivable plus
tangible personal property being purchased, exceeds or is less than
$45,000,000. The consideration to be paid by VWR for the Industrial
Distribution Business was determined by negotiations between VWR and Baxter
and approved by the Board of Directors of VWR. VWR is negotiating with Baxter
to acquire at closing additional accounts receivable of the Industrial
Distribution Business (approximately $25,000,000), expected to be paid for on
a dollar-for-dollar basis over a period not to exceed two months.
 
  Pursuant to the terms of a Services Agreement to be entered into between VWR
and Baxter (the "Services Agreement") at closing under the Asset Purchase
Agreement, Baxter will, for a
 
                                      17
<PAGE>
 
transition period of up to two years, provide VWR with certain administrative
and distribution services for the Industrial Distribution Business from
Baxter's own facilities. From time to time during such transition period VWR
will move the operations of the Industrial Distribution Business from Baxter's
facilities into its own distribution facilities. Each time such operations are
transferred from a Baxter facility to a VWR facility, VWR will purchase
certain inventories of the laboratory supplies and equipment which Baxter then
holds in that facility for sale in connection with the Industrial Distribution
Business.
 
  For Baxter's basic services under the Services Agreement, VWR will pay
Baxter monthly an amount equal to 5.5% of the total sales of the Industrial
Distribution Business which are serviced by Baxter, although no such amounts
will be payable for the first three months of the Services Agreement. The
minimum amount payable by VWR to Baxter for its basic services during the
first fifteen months under the Services Agreement is $18,645,000. In addition,
under the Services Agreement VWR will reimburse Baxter for customary net
freight expenditures incurred by Baxter in performing such basic services and
will make certain incremental payments to Baxter for any additional services
provided by Baxter to VWR.
 
  At closing under the Asset Purchase Agreement, VWR and Baxter will also
enter into a Distribution Agreement (the "Baxter Distribution Agreement")
pursuant to which VWR will be granted the right to sell and distribute certain
Baxter-manufactured products to customers for use in laboratories, production
plants and other facilities not involved in the care of human patients or the
diagnosis of disease or defect for the purpose of care of human patients. The
Baxter Distribution Agreement, which will continue until September 30, 2000
(and be automatically renewed for successive one-year terms thereafter unless
terminated as provided therein), imposes specified minimum purchase
obligations on VWR which increase annually over its term.
 
  Baxter's principal executive offices are located at One Baxter Parkway,
Deerfield, Illinois, 60015 and its telephone number at such offices is (708)
948-2000.
 
DESCRIPTION OF OTHER FINANCING OF THE ACQUISITION
 
  In addition to the financing to be provided by the transactions with EML
described above in this Proxy Statement, the Corporation will require senior
bank financing for the Acquisition and the post-Acquisition conduct of its
increased business operations. Each of Bank of America National Trust and
Savings Association, PNC Bank and CoreStates Bank, N.A. (collectively, the
"Banks") have entered into a commitment letter (the "Commitment Letter") with
the Corporation. The Commitment Letter sets forth the terms under which,
subject to the negotiation and execution of a mutually satisfactory loan
agreement and other conditions set forth therein, the Banks will lend the
Corporation an aggregate of $285,000,000 (the "Senior Facility"). The
principal terms and conditions of the Commitment Letter are described below.
While BA Securities, Inc., an affiliate of Bank of America, has undertaken to
syndicate, on behalf of the Banks, a portion of the principal amount of the
Senior Facility to other participants, the commitment of each of the Banks is
not contingent on such syndication. VWR is currently discussing with Goldman,
Sachs the possible participation of Goldman, Sachs in the Senior Facility.
 
  The Senior Facility will consist of a five-year amortizing term loan of
$135,000,000 (the "Term Loan") and a revolving credit facility of $150,000,000
(the "Revolver"). The Term Loan will require scheduled principal payments, as
well as mandatory prepayments from excess cash flow (as to be defined) and
from certain types of corporate transactions (e.g., asset sales, issuances of
equity, etc.) should VWR elect to engage in any such transactions.
 
 
                                      18
<PAGE>
 
  The loans under the Senior Facility will be secured by substantially all of
the tangible and intangible personal property of the Corporation and its
subsidiaries and the Corporation will agree not to create any liens on its
real property. The Corporation will be obligated to grant liens on its real
property to secure the Senior Facility in the event the Banks should later
request it to do so.
 
  Both the Term Loan and the Revolver will bear interest rates based, in such
relative principal amounts as the Corporation shall elect, on the London
Interbank Offered Rate ("LIBOR") or the prime rate announced from time to time
by CoreStates Bank, N.A. ("Prime"). The Corporation will be obligated to pay
amounts in excess of such floating rates (between .75% and 2.5% in the case of
LIBOR elections and 0% and 1% in the case of Prime elections), which such
amounts will vary depending upon the relationship between the Corporation's
earnings before interest, taxes, depreciation and amortization ("EBITDA") and
the then aggregate amount outstanding under the Senior Facility. The
Corporation would also be required to pay a commitment fee on the unused
portion of the Revolver of between .25% and .5%, also varying depending on the
relationship between the Corporation's EBITDA and aggregate borrowings under
the Senior Facility.
 
  The terms of the Revolver will provide that the Corporation must have at
least $20,000,000 undrawn on the Revolver for at least thirty consecutive days
in the first twelve months following the closing and at least $30,000,000
undrawn for at least thirty consecutive days during each twelve month period
thereafter. Borrowings under the Revolver will be limited to 85% of eligible
accounts receivable and 50% of the eligible inventory.
 
  The definitive documentation will include various financial covenants of the
Corporation, including covenants with respect to minimum EBITDA, maximum
senior leverage ratio, minimum interest coverage, minimum net worth, and
minimum consolidated fixed coverage rates. The definitive documentation will
also include other customary covenants in loan agreements of this type,
customary representations and warranties, and customary conditions to each
drawing.
 
VWR'S REASONS FOR THE ACQUISITION
 
  VWR operates in a market which demands that distribution companies operate
more efficiently to remain profitable and competitive. Over the past few years
VWR's management has taken several steps to operate more efficiently. The
consolidation and restructuring of certain regional and corporate functions
are examples of cost-saving steps VWR has undertaken since 1993. While these
steps have created cost savings, VWR's current infrastructure (including,
without limitation, facilities and systems) is capable of absorbing a higher
level of sales and to realize substantial further efficiencies, VWR must
increase the volume of products flowing through its warehouses to further
absorb fixed warehousing and other selling, general and administrative costs.
 
  Facing similar market demands in Canada, VWR has been able to create
operating efficiencies by increasing volume and sales through integration of
acquired businesses into VWR's Canadian infrastructure. VWR began expanding
its market share in Canada with the acquisition of John's Scientific, Inc. in
1992. In October 1994, VWR acquired the laboratory supply business of Canlab,
a division of Baxter Corporation, an affiliate of Baxter.
 
  VWR believes that it is necessary for it to expand further its domestic and
international customer and revenue base to achieve certain marketing and other
efficiencies, which would allow VWR to compete more effectively and
profitably. VWR's Board has concluded that the Acquisition is an attractive
method of expanding its customer base and volume both currently and in the
future and utilizing existing capacity in its domestic infrastructure.
 
 
                                      19
<PAGE>
 
  As a result of the Acquisition, VWR is expected to have approximately $1
billion in sales and will be one of the largest distributors in the
approximate $7-8 billion industrial, government and education laboratory
supply market. VWR expects to achieve several synergies from the combination,
which VWR believes will result in improved operating performance. VWR expects
to phase in the integration of the Industrial Distribution Business within
approximately 18 months of the closing date of the Acquisition. Operating
efficiencies and synergies are anticipated to include, among other things:
 
  .  The expected economies that potentially can be achieved by combining the
     two similar businesses without a proportionate increase in overhead
     through the consolidation of office and distribution facilities and
     functions.
 
  .  Utilization of excess capacity of VWR's current infrastructure by
     increasing the volume of products that flow through VWR's warehouses and
     thus spreading fixed costs (including selling, general and
     administrative expenses) over a much larger base of sales.
 
  .  Revenue enhancement potential resulting from the cross-selling
     opportunities between the two businesses including sales to VWR's
     customers of Baxter's critical environmental products for non-patient
     care, and to Baxter's customers of VWR's furniture products. Under the
     Baxter Distribution Agreement, VWR will have immediate access to
     products manufactured by Baxter for VWR's sale for use in cleanrooms and
     critical environments. This access will give VWR a significantly broader
     product line and VWR believes it will make it a more attractive
     supplier.
 
  .  The significant overlap of the relationships that VWR and Baxter have
     with customers and vendors will allow for an efficient integration of
     the two businesses. It will also provide purchasing economies with
     vendors due to increased volume.
 
RISKS TO VWR ASSOCIATED WITH THE ACQUISITION
 
  For the reasons stated above, the Corporation's Board of Directors believes
that the Acquisition is in the best interests of the Corporation and its
shareholders. However, shareholders should be aware of the fact that the
Acquisition, and the financing required to effect the Acquisition (including
the Corporation's transactions with EML discussed under "Issuance of
Additional Common Shares to EML"), involve risks to VWR, including but not
limited to the following:
 
  .  Successful integration of the Industrial Distribution Business into VWR
     may ultimately require greater time and expense than are currently
     anticipated by VWR's management.
 
  .  The expected synergies of the Acquisition may not be fully realized or
     their realization may be significantly delayed.
 
  .  The successful integration of the Industrial Distribution Business into
     VWR will be significantly dependent upon VWR's ability to attract and
     retain the personnel (including those who are now Baxter employees)
     necessary to effectively integrate, and thereafter operate, the combined
     businesses. (See "Issuance of Additional Common Shares to EML--Certain
     Officers' Agreements.")
 
  .  The adequacy of the Corporation's post-Acquisition revenues to service
     its substantially increased indebtedness and to meet expenses generally
     will be dependent upon the Corporation's ability to retain both its
     historic customer base and those customers which were formerly customers
     of the Industrial Distribution Business in the context of an extremely
     competitive distribution marketplace.
 
  .  As a result of the Acquisition the Corporation's debt-to-equity ratio
     will increase from 1.95-to-1.00 at March 31, 1995 to 2.39-to-1.00 on a
     pro-forma basis. Also, VWR's consolidated long-term debt will increase
     from an actual outstanding amount of $79.1
 
                                      20
<PAGE>
 
     million at March 31, 1995 to $372.7 million on a pro-forma basis. As a
     result, the Corporation's pro forma interest expense for the year ended
     December 31, 1994, including $17.5 million of interest expense related
     to the Debenture which will be paid with Common Shares, approximates
     $36.4 million compared to $5.1 million actually incurred in the year
     ended December 31, 1994. The extent of its indebtedness, both senior and
     subordinated, may make it difficult for the Corporation to borrow
     additional funds in its future, if needed, and may increase
     substantially the cost to VWR of any additional borrowings even if such
     funds are available.
 
  .  During at least the first six months of the Services Agreement, most of
     the Industrial Distribution Business will be serviced by Baxter.
     Accordingly, while Baxter covenants to perform services under such
     Agreement in a manner consistent with past practice and with the same
     degree of care, skill and prudence customarily exercised by it in
     providing similar services to its own operating divisions prior to the
     date of such Agreement, the failure of Baxter to provide such services
     in a satisfactory manner could be expected to have a material adverse
     effect on VWR's results of operations and condition (financial or
     otherwise).
 
  .  In each year during the term of the Baxter Distribution Agreement, VWR
     will be required to meet substantial minimum purchase requirements or,
     if such minimums are not achieved, to purchase products or pay to Baxter
     an amount, in each case, equal to any deficiency. Such minimum
     requirements increase in each successive year. The failure of VWR to
     meet such minimum purchase requirements because of its inability to
     resell the products it is required to purchase from Baxter could be
     expected to have a material adverse effect on VWR's results of
     operations and condition (financial or otherwise). The minimum purchase
     requirement of $63,000,000 for the first contract year under the Baxter
     Distribution Agreement represents an approximate 12.5% increase over the
     annualized unaudited sales of the Industrial Distribution Business of
     comparable products during the quarter ended March 31, 1995. (See
     "Description of the Acquisition of the Industrial Distribution
     Businesses of Baxter Healthcare Corporation--Other Material Contacts--
     Baxter Distribution Agreement.")
 
OPINION OF FINANCIAL ADVISER RELATING TO THE ACQUISITION
 
  Goldman, Sachs delivered to the VWR Board of Directors its written opinion
that, as of May 24, 1995, the consideration to be paid by VWR for the
Industrial Distribution Business pursuant to the Asset Purchase Agreement is
fair to VWR. Goldman, Sachs received no instructions from VWR, nor were any
limitations imposed by VWR or its affiliates on the scope of the investigation
made or procedures followed in connection with its fairness opinion. The full
text of the opinion of Goldman, Sachs dated May 24, 1995, which sets forth
assumptions made, matters considered and limits on the review undertaken, is
attached as Exhibit V to this Proxy Statement. VWR SHAREHOLDERS ARE URGED TO
READ THE GOLDMAN, SACHS OPINION CAREFULLY AND IN ITS ENTIRETY. In the opinion
of VWR's management, since May 24, 1995, no events have occurred, and there
has been no significant change in any information available to Goldman, Sachs
which should alter Goldman Sachs' opinion given as of such date. The summary
of the opinion of Goldman, Sachs as set forth in this Proxy Statement is
qualified in its entirety by reference to the full text of such opinion.
Goldman, Sachs' opinion is with respect only to the fairness of the
consideration to be paid by VWR to Baxter in connection with the Acquisition
and does not constitute a recommendation to any VWR shareholder as to how to
vote upon the issuance of the EML Shares to EML nor does it any way constitute
an opinion regarding the fairness to VWR of the consideration paid by EML for
the EML Shares and the Debenture.
 
  In connection with its opinion, Goldman, Sachs reviewed, among other things,
the Asset Purchase Agreement (including the exhibits thereto), the Annual
Reports to Shareholders and
 
                                      21
<PAGE>
 
Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q of VWR and
Baxter for the five years ended December 31, 1994. For the Industrial
Distribution Business, Goldman, Sachs reviewed certain internal financial
analyses, unaudited financial results for the three years ended December 31,
1994, and projected sales and gross profit for 1995 prepared by Baxter, and
projected financial forecasts for 1995-1999 prepared by VWR as of April 20,
1995. Goldman, Sachs noted that audited financial information for the
Industrial Distribution Business had not been prepared and, accordingly, had
not been reviewed by it. Goldman, Sachs also held discussions with members of
the senior managements of Baxter and the Industrial Distribution Business
regarding their respective past and current business operations and financial
condition. Goldman, Sachs also held discussions with members of the senior
management of VWR, Baxter and the Industrial Distribution Business regarding
future prospects of the Industrial Distribution Business. In addition,
Goldman, Sachs compared certain financial information for the Industrial
Distribution Business with similar information for certain other companies the
securities of which are publicly traded, reviewed the financial terms of
certain recent business combinations in the distribution industry specifically
and in other industries generally and performed such other studies and
analyses as it considered appropriate. Goldman, Sachs expressed no opinion
with respect to any transaction undertaken by VWR to finance the transactions
pursuant to the Asset Purchase Agreement.
 
  Goldman, Sachs relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by it for
purposes of its opinion. In that regard, Goldman, Sachs assumed, with VWR's
consent, that the projected sales and gross profit for 1995 prepared by Baxter
and the financial forecasts prepared by VWR, including, without limitation,
projected cost savings and operating synergies resulting from the acquisition
of the Industrial Distribution Business by VWR and other acquisition-related
adjustments have been reasonably prepared on a basis reflecting the best
currently available judgments and estimates of Baxter and VWR and that such
forecasts will be realized in the amounts and at the times contemplated
thereby. In addition, Goldman, Sachs has not made an independent evaluation or
appraisal of the assets and liabilities of the Industrial Distribution
Business. Goldman, Sachs has not been furnished with any such evaluation or
appraisal. Goldman, Sachs also assumed that VWR will receive all necessary
regulatory approvals to complete the transactions contemplated by the Asset
Purchase Agreement without undue delay.
 
  Goldman, Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements,
and valuations for estate, corporate and other purposes. Goldman, Sachs is
familiar with VWR having acted as its financial advisor in connection with,
and having participated in certain of the negotiations leading to, the Asset
Purchase Agreement and is discussing with VWR its participation in the senior
bank financing to be used for the Acquisition and the post-Acquisition conduct
of VWR's business. Goldman, Sachs also provided, and may provide in the
future, certain investment services to Baxter unrelated to the Acquisition.
Recent investment banking services provided to Baxter International Inc. by
Goldman, Sachs include serving as a managing underwriter of public offerings
of its debt securities and acting as agent to its commercial paper program.
 
  Goldman, Sachs provides a full range of financial, advisory and brokerage
services and in the course of its normal trading activities may from time to
time effect transactions and hold positions in the securities or options on
securities of VWR and/or Baxter International Inc. for its own account and for
the account of customers of Goldman, Sachs. As of May 24, 1995, Goldman, Sachs
held for its own account a net short position of 21,754 of the shares of
Baxter International Inc.
 
 
                                      22
<PAGE>
 
  Pursuant to a letter agreement dated September 8, 1994 (the "Engagement
Letter"), VWR engaged Goldman, Sachs to act as its financial advisor in
connection with the possible acquisition of all or a portion of the stock or
assets of the Industrial Distribution Business. Pursuant to the terms of the
Engagement Letter, VWR has paid Goldman, Sachs an initial fee of $150,000 (the
"Initial Fee"), and has agreed to pay Goldman, Sachs an ongoing monthly
retainer fee of $75,000 per month commencing after April 30, 1995 (the
"Monthly Retainer Fee"). VWR has also agreed to pay Goldman, Sachs a
transaction fee of $3,000,000 if, among other things, at least 50% of the
assets of the Industrial Distribution Business are acquired by VWR. The
Initial Fee and any Monthly Retainer Fee would be credited against any such
transaction fee. VWR has agreed to reimburse Goldman, Sachs for its reasonable
out-of-pocket expenses, including attorneys' fees and disbursements plus any
sales, use or similar taxes (including additions to taxes, if any) arising in
connection with the engagement. To date Goldman, Sachs has not received any
reimbursement of out-of-pocket expenses. Goldman, Sachs estimates that its
out-of-pocket expenses, including fees and expenses of its counsel, amount to
approximately $24,400. VWR has also agreed to indemnify Goldman, Sachs against
certain liabilities, including certain liabilities under the federal
securities laws.
 
REGULATORY APPROVALS
 
  The Corporation and Baxter have made all requisite filings under the HSR Act
and the applicable waiting period has been terminated.
 
SUMMARY OF THE ASSET PURCHASE AGREEMENT
 
  The Asset Purchase Agreement is attached as Exhibit VI to this Proxy
Statement and is incorporated herein by reference.
 
  Purchase of Industrial Distribution Business. In the Acquisition, the
Corporation will purchase from Baxter certain specified assets (the "Purchased
Assets") and assume certain liabilities, in each case, associated with the
Industrial Distribution Business, for $400,000,000, subject to adjustment as
set forth in the Asset Purchase Agreement. For a period of up to 24 months
after the Closing Date, Baxter will provide, on a region-by-region basis,
certain services in connection with VWR's sales to customers of the Industrial
Distribution Business pursuant to the terms and conditions of the Services
Agreement. In addition, Baxter will supply certain of its manufactured
products to VWR for distribution to customers of the Industrial Distribution
Business and other customers of VWR pursuant to the terms of the Baxter
Distribution Agreement. The Services Agreement and the Baxter Distribution
Agreement are described in more detail below.
 
  Employees of Industrial Distribution Business. VWR will offer employment to
all of the employees of Baxter's Industrial Distribution Business (the
"Business Employees"). As of April 26, 1995, there were approximately 570
Business Employees. Subject to certain limitations, VWR and Baxter will share
equally amounts payable to those Business Employees who reject such offers of
employment from VWR and are not retained by Baxter and who are eligible for
severance benefits under Baxter's policies.
 
  Conditions to the Acquisition. The respective obligations of the Corporation
and Baxter to consummate the Acquisition are subject to the satisfaction of
the following conditions, any or all of which may be waived by VWR and Baxter
to the extent permitted by applicable law: (a) the issuance of the EML Shares
by VWR to EML shall have been duly approved by the requisite vote of VWR's
shareholders in accordance with law and applicable rules, regulations and
practices of the Nasdaq Stock Market, (b) the applicable waiting periods under
the HSR Act or any extensions thereof with respect to the Acquisition shall
have expired and no injunction or restraining order
 
                                      23
<PAGE>
 
shall have been issued by any court of competent jurisdiction and be in effect
which restrains or prohibits any material transaction contemplated by the
Asset Purchase Agreement; (c) the parties shall have executed and delivered
the Baxter Distribution Agreement and the Services Agreement; and (d) certain
other customary conditions such as the accuracy of representations and
warranties, performance of agreements and covenants and the lack of certain
governmental proceedings.
 
  Non-Competition. With certain exceptions, Baxter has agreed for a three-year
period following the Closing Date not to enter into any business in
competition with VWR. Such exceptions include the purchase as a passive
investor of up to 8% of the outstanding publicly-traded shares of any
corporation, the purchase of equity interests of an entity with direct and
indirect net sales of laboratory equipment and supplies (to customers which
purchase products distributed by the Industrial Distribution Business) which
do not exceed $100,000,000 in such entity's most recently completed fiscal
year, the continued carrying on of any aspect of Baxter's medical/surgical
supplies or medical/surgical diagnostics businesses for clinical uses as
operated as of the Closing, and the selling and distributing of products
competitive with or the same as the products of the Industrial Distribution
Business to laboratories and other facilities of a clinical customer if such
clinical customer conditions the sale of medical/surgical or diagnostic
products upon the sale and distribution of such other products to its non-
clinical laboratories and other facilities.
 
  Indemnification. The Asset Purchase Agreement provides each party with the
right to seek indemnification for such customary matters as any (i) breach of
or inaccuracy in any representation or warranty; (ii) breach or nonfulfillment
of any agreement or covenant; or (iii) failure to satisfy any excluded/assumed
liability. Except for matters relating to the excluded/assumed liabilities,
the rights of a party to seek indemnification is limited in certain respects,
including, (i) a claim for indemnification may not be made until, and then
only to the extent, that the total of all losses exceeds $1,000,000; (ii) a
claim may not be made after two years following the Closing; and (iii) the
maximum aggregate liability of a party in respect of all claims for
indemnification is limited to $300,000,000.
 
  Termination and Expiration; Liquidated Damages. The Asset Purchase Agreement
may be terminated by either party if the Closing shall not have occurred on or
before October 31, 1995 because of the failure to satisfy any condition
precedent to the obligations of such party. The Asset Purchase Agreement
provides that if the Closing has not occurred due to the inability of a party
to fulfill certain conditions required of it prior to Closing, that party will
be obligated to pay $5,000,000, and no more, to the other party as liquidated
damages. In addition, if the shareholders of VWR do not approve the issuance
and sale of the EML Shares, VWR will be obligated to pay $5,000,000, and no
more, to Baxter as liquidated damages. No payment is due from any party if the
Asset Purchase Agreement is terminated or expires due to antitrust matters.
 
OTHER MATERIAL CONTRACTS
 
  The Services Agreement and the Baxter Distribution Agreement are attached
hereto as Exhibits VII and VIII, respectively, and are incorporated herein by
reference.
 
  Services Agreement. The Services Agreement governs the provision by Baxter
of certain services to VWR to enable the uninterrupted continuation of the
Industrial Distribution Business after the Closing as well as an orderly
transfer of the Industrial Distribution Business to VWR. Under the Services
Agreement, Baxter will continue to provide the same type of services to the
customers of the Industrial Distribution Business after the date of Closing as
it had provided prior to such date. Such services include order entry,
shipping, invoicing, credit and collection, and inventory stocking and
replenishment. While the term of the Services Agreement is for two years,
 
                                      24
<PAGE>
 
upon prior notice, VWR may direct Baxter to discontinue the provision of
services in any particular region. No service fees are payable for services
under the Services Agreement during the first three months of the term of such
Agreement. VWR will make monthly payments during the remaining term of the
Services Agreement to Baxter at the rate of 5.5% of the total sales of certain
products sold to customers of the Industrial Distribution Business which are
serviced by Baxter; provided, VWR will be obligated to pay a minimum of
$18,645,000 to Baxter during the first fifteen months of such Agreement. Upon
the cessation of services by Baxter at a particular facility, VWR will be
required to purchase from Baxter the inventory of laboratory supplies and
equipment held by Baxter at such facility for sale to customers of the
Industrial Distribution Business.
 
  Baxter Distribution Agreement. Under the Baxter Distribution Agreement,
Baxter will grant to VWR the right to sell and distribute for non-patient use
(anywhere except in Canada) certain products and accessories manufactured by
Baxter and its affiliates. The Baxter Distribution Agreement, which has a term
ending on September 30, 2000, provides, among other things, that VWR will be
obligated during each year to either purchase a minimum dollar amount of
products for sale in each of the United States and internationally, or, if
such minimum requirements have not been met during such year, purchase
products or pay to Baxter an amount, in each case, equal to any such
deficiency. The minimum aggregate domestic and international requirements for
each of the five years of the Baxter Distribution Agreement are as follows:
Year 1--$63,000,000; Year 2--$74,000,000; Year 3--$82,000,000; Year 4--
$89,000,000; and Year 5--$96,000,000.
 
ACCOUNTING FOR THE ACQUISITION
 
  VWR will account for the transaction under the purchase method of
accounting. The Corporation will allocate the purchase price to the estimated
fair values of the assets acquired and liabilities assumed, with the excess
recorded as goodwill. VWR estimates the amount of the purchase price allocable
to goodwill will approximate $361,000,000 which will be amortized to
operations on a straight-line basis over 40 years. The results of operations
of the Industrial Distribution Business will be included in VWR's financial
statements from the effective date of the Acquisition.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The Acquisition will be in the form of a purchase of assets for cash and the
assumption of certain liabilities. Other than acquired accounts receivable,
substantially all of the purchase price in the acquisition will be allocable
to intangible assets such as goodwill and going concern value and,
accordingly, will be amortizable by VWR over fifteen years for federal
corporate income tax purposes. Neither VWR nor its shareholders will recognize
any income or gain for federal income tax purposes by reason of the issuance
of VWR shares to EML or by reason of the completion of the Acquisition.
 
PRIOR TRANSACTION
 
  On October 31, 1994, VWR (through a wholly-owned subsidiary) acquired for
approximately $13,900,000 the business and certain assets of the Canlab
division ("Canlab") of Baxter Corporation, an affiliate of Baxter. Canlab was
engaged (solely in Canada) in the distribution of general laboratory products
to industrial users (a business which was similar to that currently conducted
by the Industrial Distribution Business) and biomedical users.
 
CORPORATE NAME CHANGE
 
  Upon the closing of the Acquisition, VWR is expected to change its corporate
name from "VWR Corporation" to "VWR Scientific Products Corporation."
 
                                      25

MARKET DATA
 
  On May 24, 1995, the last trading day prior to the joint announcement by VWR
and Baxter that they had executed the Asset Purchase Agreement, the high and
low per share sales price of VWR's Common Shares, as reported by the Nasdaq
Stock Market, were $10.00 and $9.25, respectively.
 
            INFORMATION ABOUT THE INDUSTRIAL DISTRIBUTION BUSINESS
 
  The following information about the Industrial Distribution Business has
been supplied by Baxter for inclusion in this Proxy Statement.
 
DESCRIPTION OF BUSINESS
 
  The Industrial Distribution Business is in the business of distributing
general laboratory supplies and equipment to customers such as analytical
research and development laboratories, educational institutions, environmental
testing laboratories, cleanroom facilities, medical device manufacturers,
electronic and semiconductor manufacturers, government research facilities and
others. The Industrial Distribution Business is one of the largest
distributors of laboratory equipment and supplies in the United States, with
1994 domestic and international sales of approximately $471,000,000. The
Industrial Distribution Business does not include Baxter's distribution of
products, whether manufactured by it or by others, in Japan and Canada or to
customers of Baxter who purchase such products for use in the care of human
patients or for the diagnosis of disease or defect for the purpose of caring
for human patients.
 
CUSTOMERS AND SUPPLIERS
 
  The Industrial Distribution Business serves two customer categories: non-
clinical laboratories and research facilities, and the cleanroom industry. The
Industrial Distribution Business has approximately 40,000 active customers.
Although many of the Fortune 100 companies are counted among the Industrial
Distribution Business customers base, no one customer accounts for more than
3% of total revenues.
 
  The Industrial Distribution Business has supply and distribution
relationships with approximately 2,000 manufacturers. Approximately 80% of the
total revenues of the Industrial Distribution Business come from the sale of
products from the top 25 of these suppliers, which include Baxter
manufacturing units. Many suppliers assist in the marketing and sales of their
products by maintaining a technical salesforce which works with Industrial
Distribution Business sales representatives.
 
COMPETITION
 
  The Industrial Distribution Business competes with several national
distributors and many smaller, regional distributors. In addition, there are a
number of manufacturers of laboratory chemicals, supplies, and equipment that
sell directly to customers and do not go through distributors.
 
DESCRIPTION OF PROPERTY
 
  The Industrial Distribution Business utilizes Baxter's distribution
infrastructure of warehouses and transportation fleet, and is charged at
Baxter's cost for doing so, thus there is minimal property, plant and
equipment of the Industrial Distribution Business.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF THE INDUSTRIAL DISTRIBUTION BUSINESS
 
  The following is a discussion of the financial condition and results of
operations of the Industrial Distribution Business. The discussion should be
read in conjunction with the combined financial statements and the notes
thereto included elsewhere in this Proxy Statement.
 
OVERVIEW
 
  The Industrial Distribution Business distributes a wide variety of products
used by industry, government, and research and educational institutions. These
customers consist of laboratories, production plants and other facilities not
involved in the care of human patients. Products distributed include
consumable glass and plasticware, laboratory equipment, gloves and other
apparel, safety supplies, and laboratory chemicals. The Industrial
Distribution Business competes against several other national distributors and
numerous regional and local distributors. In
 
                                      27
<PAGE>
 
addition, the Industrial Distribution Business competes against various
manufacturers who ship directly to end users without going through
distributors.
 
RESULTS OF OPERATIONS
 
  The following table shows selected information concerning the results of
operations for the three years ended December 31, 1994:

</TABLE>
 
  The sales increases in 1994 and 1993 were achieved by a combination of
Baxter management's actions to refocus the Industrial Distribution Business on
its historical core competencies of laboratory chemicals and general
laboratory products in medium and small accounts. In addition, the Industrial
Distribution Business began its strategic focus on cleanroom manufacturing
through its Critical Environments program by deploying a dedicated salesforce,
and by the addition of new, key suppliers' product lines.
 
  Gross profit margins declined in 1994 and 1993 due to competitive pressures
in the market, especially in the areas of general laboratory products and
laboratory chemicals. These pressures have been offset to some degree by a
favorable mix shift to higher-margin, proprietary product lines, and by
programs and incentives to improve margins. Such programs and incentives
included implementing price increases when possible and aggressively focusing
on limiting supplier cost increases. Additionally, performance measures for
management included targets for margin improvement.
 
  The 1993 increase in marketing and administrative expenses reflects the
investments made in the Critical Environments sales and marketing
organization. The 1994 decrease in marketing and administrative expenses
reflects the efficiencies obtained through Baxter's U.S. Distribution
Division's cost reduction program implemented in 1993. This cost reduction
program primarily involved the consolidation of Baxter's distribution
businesses. This consolidation resulted in cost savings in operations
management, systems and administrative functions.
 
  The increase in income before income taxes and cumulative effect of
accounting change for 1994 was driven by a combination of increases in
revenues and focused management of expense growth, partially offset by higher
costs and competitive pricing.
 
 
                                      28
<PAGE>
 
  The effective tax rate for 1994 was 41.6% versus 41.1% and 41.0% for 1993
and 1992. This change reflects domestic statutory rates for both federal and
state taxes, combined with provisions for foreign taxes for the increasing
amount of international business.

operations for the three months ended March 31, 1995 and 1994 (unaudited):

</TABLE>
 
 
  Net sales for the quarter ended March 31, 1995 increased over the comparable
period in 1994 primarily as a result of the increased focus on the Critical
Environments program. As discussed previously, this focus was implemented in
1994 through the establishment of a dedicated salesforce and key suppliers'
product lines.
 
  The gross profit margin for the three months ended March 31, 1995 improved
slightly from the similar period of 1994. Margin has been maintained through
management's efforts to limit cost increases from suppliers and improve the
mix of higher margin product lines.
 
  The decrease in marketing and administrative expenses as a percentage of
sales for the three months ended March 31, 1995 as compared to the same period
in 1994 reflects the Industrial Distribution Business' share of savings from
efficiencies gained through Baxter's U.S. Distribution Division's cost
reductions implemented throughout 1993 and 1994, and the strong growth rate in
revenues.
 
  The increase in income before income taxes for the three months ended March
31, 1995 versus the comparable period of 1994 was driven by sales growth, a
slight margin improvement over the prior year and expense growth leverage.
 
ADOPTION OF NEW ACCOUNTING STANDARDS
 
  The Industrial Distribution Business adopted FASB Statement No. 109,
"Accounting for Income Taxes" effective January 1, 1993. The effect on the
Industrial Distribution Business' financial statements of adopting this
statement was immaterial. The 1992 charge for the cumulative effect of
adopting FASB Statement No. 106, "Employers' Accounting for Postretirement
Benefits Other Than Pensions" covering the accounting for retiree benefits
other than pensions, was $.5 million (net of $.3 million of income tax
benefit). Statement No. 106 was adopted during the fourth quarter of 1992,
retroactive to January 1, 1992.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash generated by the Industrial Distribution Business is transferred to
Baxter affiliates as generated. Accordingly, the balance sheets of the
Industrial Distribution Business reflect no cash balances. Funds required for
capital expenditures or other uses have been obtained from operating cash flow
or from advances from Baxter. There is no debt associated with the Industrial
 
                                      29
<PAGE>
 
Distribution Business. Historically, the Industrial Distribution Business has
been a net generator of cash to Baxter affiliates. See the Combined Statements
of Cash Flows for the Industrial Distribution Business included elsewhere in
this Proxy Statement.
 
  For the three years ended December 31, 1994, cash flow provided by
operations (which includes working capital components) increased to $18.2
million for 1994 from a level of $10.4 million in 1993. This increase
primarily reflects improved profitability and reduction in inventory, offset
by an increase in accounts receivable. The increase in accounts receivable was
primarily the result of the 1994 relocation of the Industrial Distribution
Business' credit and collection function to Baxter's Shared Services Division
in New Mexico, which has resulted in increased days sales outstanding during
the transition period. The 1993 cash flow provided by operations of $10.4
million decreased from 1992 because of lower net earnings and an increase in
inventories, as the Industrial Distribution Business focused on improved
service levels to customers and built inventory levels for the Critical
Environments program. The decrease in cash flow (used in) provided by
operations for the three months ended March 31, 1995 as compared to the same
period in 1994 was primarily the result of increases in accounts receivable
due to the relocation of the Industrial Distribution Business' credit and
collection function.
 
  The Industrial Distribution Business' current assets exceeded current
liabilities by $58.5 million at December 31, 1994 and $51.8 million at
December 31, 1993. Current assets included receivables of $62.5 million and
inventories of $40.8 million at December 31, 1994. Current assets included
receivables of $52.0 million and inventories of $43.6 million at December 31,
1993. Current assets exceeded current liabilities by $67.7 million at March
31, 1995 and included accounts receivable of $70.9 million and inventories of
$42.6 million. These sources of liquidity are convertible into cash over a
relatively short period of time and thus, will help the Industrial
Distribution Business satisfy normal operating cash requirements.
 
  The Industrial Distribution Business utilizes Baxter's distribution
infrastructure of warehouses and transportation fleet, and is charged at
Baxter's cost for doing so, thus there is minimal property, plant and
equipment on the Industrial Distribution Business' balance sheet.

                          VWR SELECTED FINANCIAL DATA
 
  The selected financial data set forth below as of and for each of the years
in the five-year period ended December 31, 1994 are derived from the audited
consolidated financial statements of VWR. The selected financial data set
forth below as of, and for each of the three months ended, March 31, 1995 and
1994 are derived from the interim unaudited condensed consolidated financial
statements of VWR. The information for such three month interim periods is
unaudited; however, in the opinion of VWR's management, all adjustments
(consisting only of normal recurring adjustments) necessary for a fair
presentation of such information have been included. Operating results for the
three months ended March 31, 1995 may not be indicative of the results that
may be achieved for the year ending December 31, 1995.
 
  The selected financial data should be read in conjunction with the Company's
consolidated financial statements and related notes thereto and Management's
Discussion and Analysis of Results of Operations and Financial Condition
incorporated by reference in this Proxy Statement.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
 
  The unaudited pro forma combined balance sheet as of March 31, 1995 set
forth below gives effect to the: (i) issuance of 9,617,993 Common Shares to
EML resulting in net proceeds of $115.1 million and borrowings of $135 million
from EML under the Debenture (collectively referred to as the "EML
Investment"); (ii) execution of the proposed $285 million credit agreement
under the Senior Facility (the "Refinancing"); and (iii) the proposed
Acquisition, as if such transactions had occurred on March 31, 1995. The pro
forma financial statements give simultaneous effect to the three transactions
because the impact of the Acquisition and the EML Investment may influence the
shareholders' vote on the issuance of the Common Shares. The proposed
Acquisition is to be accounted for under the purchase method of accounting.
Pursuant to the Asset Purchase Agreement, VWR is not acquiring inventories and
certain trade accounts receivables nor assuming accounts payable and certain
liabilities. However, these working capital items relate to operations of the
acquired business and accordingly, the pro forma balance sheet includes $28.2
million of receivables, $42.6 million of inventories and $42.8 million of
accounts payable. VWR and Baxter negotiated a two-year services agreement
("Services Agreement") whereby, among other things, Baxter will continue to
own and warehouse the inventory related to the Industrial Distribution
Business and VWR will pay Baxter for the inventory upon shipment to customers.
At various stages during the Services Agreement period, VWR will transfer
certain inventories related to the Industrial Distribution Business into VWR's
warehouses. Upon each transfer, VWR is committed to purchase all of the
transferred Baxter inventory at cost as provided in the Services Agreement and
VWR expects to fund such purchases from cash generated from operations and
available borrowings under its then-current credit facility.
 
  The unaudited pro forma combined statements of operations for the year ended
December 31, 1994 and the three months ended March 31, 1995 set forth below
give effect to the EML Investment, Refinancing and Acquisition, as if such
transactions had occurred as of January 1, 1994. The financial statements of
the Industrial Distribution Business reflect the "carve-out" financial
position and results of operations of the Industrial Distribution Business.
Certain general and administrative expenses of Baxter have been allocated to
the Industrial Distribution Business on various bases which, in the opinion of
Baxter's management, are reasonable. However, such expenses are not
necessarily indicative of, and it is not practicable for management to
estimate, the nature and level of expenses which might have been incurred had
the Industrial Distribution Business been operating as a separate independent
company. Potential cost savings from combining the operations are not
reflected in the pro forma combined statement of operations because the
Industrial Distribution Business and VWR's business are not expected to be
fully integrated until after the first anniversary date of the closing. In
addition, pursuant to the Services Agreement, VWR is required to make payments
to Baxter during the Services Agreement period equal to 5.5% of sales
processed by Baxter. The service fee is intended to compensate Baxter for
direct and indirect costs (including corporate allocations) it will incur
during the service period.
 
  The unaudited pro forma adjustments are based upon available information and
upon certain assumptions that VWR believes are reasonable. All information and
financial data concerning the Industrial Distribution Business included in
"Unaudited Pro Forma Financial Information" has been provided to VWR by
Baxter. The unaudited pro forma financial information is provided for
informational purposes only and does not purport to be indicative of VWR's
results of operations that would actually have been achieved had the EML
Investment, Refinancing and Acquisition been completed as of or for the
periods presented, or that may be obtained in the future. The pro forma
financial information should be read in conjunction with the audited and
unaudited historical financial statements of VWR and related notes thereto
incorporated by reference into this Proxy Statement, and of the Industrial
Distribution Business and related notes thereto included elsewhere in this
Proxy Statement, and "Description of the Acquisition of the Industrial
Distribution Business of Baxter Healthcare Corporation" and "Information About
the Industrial Distribution Business" included elsewhere in this Proxy
Statement.

(e) Represents borrowings under the committed $285 million Senior Facility
    that will be used to fund a portion of the purchase price and estimated
    fees related to the Acquisition and debt issuance costs. The Senior
    Facility includes a $150 million revolving facility which is payable on
    the fifth anniversary date and a $135 million term note with annual
    principal reductions beginning in the first year. The Senior Facility
    bears a fluctuating interest rate based on the prime rate or LIBOR at
    VWR's option plus an applicable margin between .75% and 2.5% in the case
    of the LIBOR election and 0% and 1% in the case of the prime rate
    election. VWR is required to enter into interest-rate protection
    arrangements for at least 25% of the facility.
 
(f) Represents the pay down of a portion of the existing revolving credit debt
    from application of proceeds from issuance of 1,818,181 Common Shares and
    the April Warrant to EML for approximately $20 million on April 13, 1995.
 
(g) Represents assumed additional borrowings related to the Industrial
    Distribution Business working capital which will not be incurred at
    closing. See note (j) below.
 
(h) Represents borrowings under the $135 million Debenture payable to EML used
    to fund a portion of the purchase price of the Acquisition. Borrowings
    under the Debenture are payable
 
                                      34
<PAGE>
 
   on the tenth anniversary date and bear interest at 13% per year payable
   quarterly as follows: by issuance of Common Shares in the first year in an
   amount that will enable EML to obtain an ownership percentage of 49.89%
   based on a fixed price of $12.44 per share; deferred in year two which will
   be paid with accumulated interest thereon at maturity of the Debenture and;
   in cash thereafter beginning in year three.
 
(i) Represents the (i) issuance of 1,818,181 Common Shares and the April
    Warrant to EML on April 13, 1995 resulting in proceeds of $20 million;
    (ii) exercise of the April Warrant to purchase 967,015 Common Shares at a
    price of $11.00 per share resulting in proceeds of $10.6 million; and
    (iii) proposed issuance of 6,832,797 Common Shares to EML for an aggregate
    of $85 million in connection with the Acquisition; less (iii) estimated
    common stock issuance cost of $.5 million.
 
(j) Includes certain assets not acquired ($28.2 million of accounts receivable
    and $42.6 million of inventory) and liabilities not assumed ($42.8 million
    of accounts payable) pursuant to the Asset Purchase Agreement. These
    assets and liabilities are related to the historical operations of the
    Industrial Distribution Business and accordingly such amounts are included
    in the pro forma balance sheet. Inventories and accounts payable of the
    Industrial Distribution Business are commingled with Baxter's US
    Distribution Division ("USD") and are allocated in the Industrial
    Distribution Business's financial statements based on the Company's
    percentage of total cost of goods sold of USD. Pursuant to the Service
    Agreement entered into between VWR and Baxter, Baxter will continue to own
    and warehouse the inventory related to the Industrial Distribution
    Business for a period of up to two years. At various stages during the
    service agreement period, VWR will transfer certain of the inventories
    related to the operations of Industrial Distribution Business into its
    warehouses. Upon each such transfer, VWR is committed to purchase such
    inventories at cost as provided in the Service Agreement. VWR expects to
    fund such purchases from cash generated from operations and available
    borrowings under its then current credit facility. Notwithstanding the
    aforementioned, VWR is negotiating with Baxter to acquire at closing
    additional accounts receivable of the Industrial Distribution Business
    (approximately $25.0 million), expected to be paid for on a dollar-for-
    dollar basis over a period not to exceed two months.

(d)Represents income tax effect of the pro forma adjustments.
 
(e) The adjusted weighted average number of outstanding shares include Common
    Shares of VWR issued or to be issued to EML as follows: (i) 1,818,181
    Common Shares issued in April 1995; (ii) 967,015 Common Shares to be
    issued upon the exercise of the April Warrant; (iii) proposed issuance of
    6,832,797 Common Shares discussed in this Proxy Statement and; (iii)
    1,410,722 Common Shares expected to be issued to satisfy interest expense
    in year one on the Debenture payable to EML which are included in the
    calculation based on the accrual of interest during the first year.
 
(f) The Industrial Distribution Business's inventory is valued at the lower of
    cost (determined on a "first-in, first-out" basis) or market. Cost of
    sales have not been adjusted to give the pro forma effect to adopt VWR's
    accounting policy to value inventory on the "last-in, first-out" ("LIFO")
    method because it is not practical to calculate the pro forma adjustment.
    Upon transfer of the inventory to VWR, the acquired inventory will be
    valued using the LIFO method of accounting.
 
                          COMPARATIVE PER SHARE DATA
 
  The following table sets forth for the periods indicated selected historical
book value, dividends and net income per share of VWR and the corresponding
pro forma equivalent per share amounts after giving effect to the following
transactions: (i) issuance of 9,617,993 Common Shares to EML resulting in net
proceeds of approximately $115.1 million and borrowings of $135 million from
EML under the Debenture (collectively referred as the "EML Investment"); (ii)
execution of the proposed $285 million credit agreement under the Senior
Facility (the "Refinancing"); and (iii) the proposed Acquisition of the
Industrial Distribution Business at a purchase price of $400 million plus
related acquisition costs of approximately $4.1 million and acquisition
liabilities of approximately $2 million. The data presented is based upon the
VWR consolidated financial statements and related notes thereto incorporated
by reference in this Proxy Statement, the Industrial Distribution Business
financial statements and related notes thereto included in this Proxy
Statement, and the unaudited pro forma financial information and related notes
thereto, also appearing in this Proxy Statement. This information should be
read in conjunction with such historical consolidated financial statements and
pro forma financial information and related notes thereto. Baxter's amounts
are not presented as such data are not applicable or are not meaningful.
 
  This data does not purport to be indicative of the results of future
operations of the combined business or the actual results that would have
occurred if the aforementioned transactions were effective as of the
respective dates indicated.

To the Board of Directors of Baxter International Inc.
 
In our opinion, the accompanying combined balance sheets and the related
combined statements of income, of cash flows and of equity present fairly, in
all material respects, the financial position of the Industrial Distribution
Business of Baxter Healthcare Corporation (the "Company") at December 31, 1994
and 1993, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1994, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express
an opinion on these financial statements based on our audit. We conducted our
audit of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audit provides a reasonable basis for the opinion expressed above.

                       INDUSTRIAL DISTRIBUTION BUSINESS
 
                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
  The Industrial Distribution Business is comprised of the Industrial and Life
Sciences Division of the U.S. Healthcare Business of Baxter Healthcare
Corporation and certain foreign operations of Baxter World Trade Corporation,
both wholly owned subsidiaries of Baxter International Inc. ("Baxter"). A
significant portion of the Industrial Distribution Business was acquired
through Baxter's 1985 acquisition of American Hospital Supply Corporation.
Goodwill related to this acquisition has been allocated to the Industrial
Distribution Business. The Industrial Distribution Business is a distributor
of third party and Baxter-manufactured laboratory and cleanroom products to
customers for use in laboratories, production plants and other facilities not
involved in the care of human patients. On May 24, 1995, Baxter entered into a
definitive agreement (the "Asset Purchase Agreement") to sell the Industrial
Distribution Business to VWR. (See Note 9)
 
  The accompanying financial statements reflect the "carve-out" financial
position, results of operations and cash flows of the Industrial Distribution
Business for the periods presented. Certain marketing and administrative
expenses of Baxter have been allocated to the Industrial Distribution Business
(See Note 3) on various bases which, in the opinion of management, are
reasonable. However, such expenses are not necessarily indicative of, and it
is not practicable for management to estimate, the nature and level of
expenses which might have been incurred had the Industrial Distribution
Business been operating as a separate independent company.
 
  The financial information included herein does not necessarily reflect what
the financial position and results of operations of the Industrial
Distribution Business would have been had it operated as a stand-alone entity
during the periods covered, and may not be indicative of future operations or
financial position.
 
  Baxter will retain certain rights and obligations after the divestiture of
the Industrial Distribution Business. Such rights and obligations were
negotiated in connection with, or are reflected in, the Asset Purchase
Agreement and related distribution and other ancillary service agreements
which will be executed between Baxter and VWR. (See Note 9)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  This summary of significant accounting policies is presented to assist the
reader in understanding and evaluating the accompanying financial statements.
These policies are in conformity with generally accepted accounting
principles, and have been applied consistently in all material respects.
 
 Inventories and Accounts Payable, Principally Trade
 
  Inventories consist of third party and Baxter-manufactured laboratory and
cleanroom products and are stated at the lower of cost (first-in, first-out
method) or market. Appropriate consideration is given to deterioration,
obsolescence and other factors in evaluating net realizable value. Inventories
and accounts payable (principally trade payables), for the Industrial
Distribution Business are commingled with Baxter's U.S. Distribution Division
("USD") and are allocated in the accompanying combined balance sheets based on
the Industrial Distribution Business' percentage of total cost of goods sold
of USD.

                       INDUSTRIAL DISTRIBUTION BUSINESS
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 Machinery and Equipment
 
  Machinery and equipment is stated at cost. Depreciation is provided for
financial reporting purposes on the straight-line method over the estimated
useful lives of the assets (ranging from 3 to 11 years depending on the nature
of the asset).
 
 Goodwill
 
  Goodwill represents the excess of cost over the fair value of net assets
allocated to the Industrial Distribution Business arising from Baxter's 1985
acquisition of American Hospital Supply Corporation, and is amortized on a
straight-line basis over 40 years. Based upon management's assessment of the
future undiscounted operating cash flows of the Industrial Distribution
Business, the carrying value of goodwill at December 31, 1994 has not been
impaired. Management reassesses the carrying value of goodwill on an annual
basis. As of December 31, 1994 and 1993, goodwill was $40.6 million and $41.9
million, respectively, net of accumulated amortization of $16.4 million and
$15.1 million, respectively.
 
 Income Taxes
 
  The operations of the Industrial Distribution Business were historically
included in Baxter's consolidated U.S. federal and state income tax returns
and in the tax returns of certain Baxter foreign subsidiaries. The provision
for income taxes shown in the accompanying financial statements has been
determined as if the Industrial Distribution Business had filed separate tax
returns under its existing structure for the periods presented. Accordingly,
the effective tax rate of the Industrial Distribution Business in future years
could vary from its historical effective rates depending on the legal
structure of and tax elections made by VWR. All income taxes, including
deferred taxes, are settled with Baxter on a current basis through the
"Investment by and advances from Baxter" account.
 
  Baxter adopted Statement of Financial Accounting Standards ("SFAS") No. 109,
"Accounting for Income Taxes", effective January 1, 1993. The effect on the
financial statements of the Industrial Distribution Business of adopting SFAS
No. 109 is immaterial. Prior to January 1, 1993, Baxter accounted for income
taxes pursuant to Accounting Principles Board Opinion No. 11, "Accounting for
Income Taxes".
 
3. RELATED PARTY TRANSACTIONS
 
  The Industrial Distribution Business participates in Baxter's centralized
cash management program with respect to intercompany sales and accounts
receivable, accounts payable, payroll and employee benefits. As a result, the
Industrial Distribution Business does not report a cash balance. Historically,
the intercompany receivables and payables have been settled in the normal
course of business, usually within 30 to 60 days, and are not interest
bearing. The net cumulative, interdivisional balances are included in the
Combined Balance Sheets as "Investments by and advances from Baxter" and
"Accounts payable--Baxter".
 
  Baxter has provided to the Industrial Distribution Business certain domestic
legal, treasury, audit, data processing, insurance, facility, regulatory and
administrative services. Charges for these services are based on allocations
of Baxter's actual direct and indirect costs using varying allocation bases as
appropriate (sales, payroll, headcount, managed capital, etc.) designed to

                       INDUSTRIAL DISTRIBUTION BUSINESS
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
estimate the actual cost incurred by Baxter to render these services to the
Industrial Distribution Business. The allocation process is also consistent
with the methodology used by Baxter to allocate the cost of similar services
provided to its other business units. The allocated cost of these services are
reflected in the combined statements of income and are summarized in the table
below. No provision has been made for possible incremental expenses that would
have been incurred had the Industrial Distribution Business operated as an
independent stand-alone entity.
 
  The Industrial Distribution Business purchases products from certain current
and former Baxter manufacturing divisions. Gross margins on Baxter-
manufactured products approximate the experience of the Industrial
Distribution Business in distributing third-party products. "Accounts
payable--Baxter" is allocated based upon Baxter's average settlement terms.
 
  The Industrial Distribution Business utilizes certain facility space and
equipment on month-to-month arrangements from Baxter. The costs allocated to

8. RETIREMENT PROGRAMS
 
  The Industrial Distribution Business participates in a Baxter-sponsored non-
contributory defined benefit pension plan covering substantially all employees
in the United States. The benefits are based on years of service and the
employee's compensation during five of the last ten years of employment as
defined by the plan. Baxter's funding policy is to make contributions to the
trust of the qualified plan which meet or exceed the minimum requirements of
the Employee Retirement Income Security Act of 1974. Assets held by the trust
of the plan consist primarily of equity and fixed income securities.

  In addition to pension benefits, the Industrial Distribution Business
participates in certain Baxter-sponsored contributory healthcare and life
insurance benefit plans for substantially all retired employees. Effective
January 1, 1992, Baxter adopted Statement of Financial Accounting Standard No.
106, "Employers' Accounting for Postretirement Benefits Other Than Pensions",
which requires companies to accrue costs for postretirement benefits over the
service years of the employees. The Industrial Distribution Business recorded
their portion of the transition obligation, $.5 million (net of $.3 million in
related income tax benefit), as a cumulative effect of an accounting change.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  Net postretirement health-care and life insurance expense ("postretirement
benefits") applicable to the Industrial Distribution Business for active
employees was not material for the years ended December 31, 1994, 1993 and
1992. The postretirement benefits plans are not funded. The present value of
the Industrial Distribution Business obligations included in the balance
sheets were not material at December 31, 1994 and 1993.
 
  Most of the employees are eligible to participate in a Baxter-sponsored
qualified 401(k) plan. Participants may contribute up to 12% of their annual
compensation (limited in 1994 to $9,240 per individual) to the plan and Baxter
matches the participants' contributions, up to 3% of compensation. Matching
contributions related to the Industrial Distribution Business employees were
$.6 million, $.6 million and $.5 million for the years ended December 31,
1994, 1993 and 1992, respectively.
 
9. SUBSEQUENT EVENT
 
  On May 24, 1995, Baxter signed a definitive agreement to sell certain assets
and liabilities of the Industrial Distribution Business to VWR for $400
million in cash, subject to certain closing conditions. Terms of the Asset
Purchase Agreement and the related distribution agreement and other ancillary
service agreements are summarized in the following paragraphs.
 
 Asset Purchase Agreement
 
  VWR will acquire certain assets of the Industrial Distribution Business
which include, but are not limited to, selected domestic accounts receivable
and related reserves, certain tangible personal property, rights and benefits
under certain contracts and rights in specified trademarks. Inventory will
remain the property of Baxter until used by VWR to fulfill orders. Once
transition from Baxter in a particular region is complete under the Services
Agreement described below, VWR will purchase certain inventories maintained in
such region by Baxter at cost. VWR will assume certain liabilities which
principally include accrued vacation pay and all liabilities for product
warranty claims. In general, Baxter will retain all other liabilities. For
additional information related to the Asset Purchase Agreement, reference
"Description of the Acquisition of the Industrial Distribution Business of
Baxter Healthcare Corporation--General Description of the Acquisition" and the
"Unaudited ProForma Balance Sheet" included elsewhere in this Proxy Statement.
 
 Baxter Distribution Agreement
 
  Baxter and VWR have agreed to enter into the Baxter Distribution Agreement
beginning at closing and ending on September 30, 2000. Each contract year will
begin on October 1 and end on September 30 except for the first contract year
which begins at closing and ends on September 30, 1996. In connection with the
agreement, Baxter grants to VWR the right to sell and distribute Baxter-
manufactured products only to Industrial Distribution Business customers for
use in laboratories, production plants and other facilities not involved in
the care of human patients. VWR may distribute such products through sub-
distributors provided the dollar volume of all products sold does not exceed
15% of the dollar volume of all products sold by VWR during the contract year
in the United States.
 
  Minimum purchase requirements, which increase annually, exist for VWR during
the first five years of the contract. If such purchase requirements are not
met, VWR is required to pay Baxter the difference between the minimum purchase
requirements and the actual purchase amounts.

                       INDUSTRIAL DISTRIBUTION BUSINESS
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
  Beginning on October 1, 1995, Baxter will pay a rebate to VWR of 5.9% of the
net purchase price for purchases in excess of $12 million in each of the first
three quarters of any contract year providing that total purchases are in
excess of $48 million for the full contract year.
 
 Services Agreement
 
  Pursuant to the Services Agreement which will become effective at closing,
Baxter will provide, among other things, certain transition services such as
order fulfillment, management information systems, credit, collections, cash
application, shipping, replenishment and warehousing to VWR in connection with
VWR's sales of products to its industrial customers. This Services Agreement
will continue for a period of up to two years. The agreement stipulates that
no payment for services is required in the first three months. Subsequent to
the first three months of the agreement, VWR is required to make monthly
payments to Baxter in an amount equal to 5.5% of the total sales of products
to industrial customers. The minimum amount payable to Baxter related to
performance of services outlined under the contract is $18.6 million in the
first 15 months.

                       INDUSTRIAL DISTRIBUTION BUSINESS
 
               NOTES TO UNAUDITED COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
  The Industrial Distribution Business is comprised of the Industrial and Life
Sciences Division of the U.S. Healthcare Business of Baxter Healthcare
Corporation and certain foreign operations of Baxter World Trade Corporation,
both wholly owned subsidiaries of Baxter International Inc. ("Baxter"). A
significant portion of the Industrial Distribution Business was acquired
through Baxter's 1985 acquisition of American Hospital Supply Corporation.
Goodwill related to this acquisition has been allocated to the Industrial
Distribution Business. The Industrial Distribution Business is a distributor
of third party and Baxter-manufactured laboratory and cleanroom products to
customers for use in laboratories, production plants and other facilities not
involved in the care of human patients. On May 24, 1995, Baxter entered into a
definitive agreement (the "Asset Purchase Agreement") to sell the Industrial
Distribution Business to VWR. (See Note 3)
 
2. INTERIM FINANCIAL INFORMATION
 
  The accompanying unaudited combined financial statements as of March 31,
1995 and for the three month periods ended March 31, 1995 and 1994, reflect
adjustments consisting of normal and recurring adjustments necessary for a
fair presentation of such financial information. These unaudited interim
combined financial statements should be read in conjunction with the audited
financial statements included elsewhere in this Proxy Statement.
 
3. SUBSEQUENT EVENT
 
  On May 24, 1995, Baxter signed a definitive agreement to sell certain assets
and liabilities of the Industrial Distribution Business to VWR for $400
million in cash, subject to certain closing conditions. Terms of the Asset
Purchase Agreement and the related distribution agreement and other ancillary
service agreements are summarized in the following paragraphs.
 
 Asset Purchase Agreement
 
  VWR will acquire certain assets of the Industrial Distribution Business
which include, but are not limited to, selected domestic accounts receivable
and related reserves, certain tangible personal property, rights and benefits
under certain contracts and rights in specified trademarks. Inventory will
remain the property of Baxter until used by VWR to fulfill orders. Once
transition from Baxter in a particular region is complete under the Services
Agreement described below, VWR will purchase certain inventories maintained in
such region by Baxter at cost. VWR will assume certain liabilities which
principally include accrued vacation pay and all liabilities for product
warranty claims. In general, Baxter will retain all other liabilities. For
additional information related to the Asset Purchase Agreement, reference
"Description of the Acquisition of the Industrial Distribution Business of
Baxter Healthcare Corporation--General Description of the Acquisition" and the
"Unaudited Pro Forma Balance Sheet" included elsewhere in this Proxy
Statement.
 
 Baxter Distribution Agreement
 
  Baxter and VWR have agreed to enter into the Baxter Distribution Agreement
beginning at closing and ending on September 30, 2000. Each contract year will
begin on October 1 and end on September 30 except for the first contract year
which begins at closing and ends on September 30, 1996. In connection with the
agreement, Baxter grants to VWR the right to sell and distribute Baxter-
manufactured products only to Industrial Distribution Business customers for
use in laboratories, production plants and other facilities not involved in
the care of human patients. VWR may distribute products through sub-
distributors provided the dollar volume of all products

         NOTES TO UNAUDITED COMBINED FINANCIAL STATEMENTS--(CONTINUED)
sold does not exceed 15% of the dollar volume of all products sold by VWR
during the contract year in the United States.
 
  Minimum purchase requirements, which increase annually, exist for VWR during
the first five years of the contract. If such purchase requirements are not
met, VWR is required to pay Baxter the difference between the minimum purchase
requirements and the actual purchase amounts.
 
  Beginning on October 1, 1995, Baxter will pay a rebate to VWR of 5.9% of the
net purchase price for purchases in excess of $12 million in each of the first
three quarters of any contract year providing that total purchases are in
excess of $48 million for the full contract year.
 
 Services Agreement
 
  In the Services Agreement to become effective at closing, Baxter will
provide, among other things, certain transition services such as order
fulfillment, management information systems, credit, collections, cash
applications, shipping, replenishment and warehousing to VWR in connection
with VWR's sales of products to its industrial customers. This Services
Agreement will continue for a period of up to two years. The agreement
stipulates that no payment for services is required in the first three months.
Subsequent to the first three months of the agreement, VWR is required to make
monthly payments to Baxter in an amount equal to 5.5% of the total sales of
the products to its industrial customers. The minimum amount payable to Baxter
related to performance of services outlined under the agreement is $18.6
million in the first 15 months.

May 24, 1995
 
CONFIDENTIAL
 
The Board of Directors
VWR Corporation
1310 Goshen Parkway
West Chester, PA 19380
 
Gentlemen:
 
  You have asked us to advise the Board of Directors with respect to certain
financial consequences to the Company of a private placement of subordinated
debt and common stock (the "Investment") of VWR Corporation (the "Company") to
EM Industries, Incorporated (the "Purchaser") under that certain Common Share
and Debenture Purchase Agreement dated May 24, 1995 (the "Placement
Agreement") entered into in connection with the Company's acquisition of
certain assets of the Industrial Products Group of the Scientific Products
Division (the "Distribution Business") of Baxter Healthcare Corporation (the
"Baxter Asset Purchase"). Pursuant to the Placement Agreement, the Company
will issue to the Purchaser a subordinated debenture due 2005 in the principal
amount of $135 million (the "Debenture") and 6,832,797 shares of common stock
of the Company at a purchase price of $12.44 per share (the "Purchased
Shares"), subject to certain conditions, including the consummation of the
Baxter Asset Purchase. We understand that the two directors of the Company
affiliated with the Purchaser are not participating in the consideration by
the Board of Directors of the Investment.
 
  PNC Securities Corp, as part of its investment banking business, is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions and valuations for corporate, estate,
and other purposes. We are currently acting as financial advisor to the Board
of Directors of the Company and will receive a fee for such services. PNC
Securities may provide investment banking and financial advisory services to
the Company in the future.
 
  In the course of our review of the Investment, we have: (i) analyzed certain
publicly available financial statements and other information of the Company,
including documentation relating to the purchase of Company common stock and a
warrant by the Purchaser on April 13, 1995; (ii) analyzed certain internal
financial statements and other financial and operating data concerning the
Company, including certain pro forma financial data giving effect to the
consummation of the Baxter Asset Purchase and related financing, prepared by
the management of the Company; (iii) analyzed certain financial projections
prepared by the management of the Company; (iv) discussed the past and current
operations and financial condition and the prospects of the Company with
senior executives of the Company, including the strategic and operating
benefits anticipated by senior management to be derived from the Baxter Asset
Purchase and the investment and commercial arrangements with the Purchaser and
discussed prior efforts to place equity securities; (v) reviewed the
historical stock prices and trading volume of the Company's common stock; (vi)
visited the principal offices of the Company; (vii) compared the financial
performance and prospects of the Company with that of certain other comparable
publicly traded companies and analyzed the market valuations of such
companies; (viii) compared certain financial terms of the Investment to
certain financial terms of selected other transactions we deemed relevant;
(ix) reviewed the principal terms of the Baxter Asset Purchase and the opinion
of Goldman Sachs & Co., the Company's financial advisor, dated May 24, 1995
with respect to the
 
                                      I-1
<PAGE>
 
fairness to the Company of the consideration to be paid by the Company for the
Distribution Business as of the date of such opinion; (x) reviewed the terms
of the Placement Agreement, including the form of the Debenture, an amended
standstill agreement and related agreements as agreed by the Company and the
Purchaser, and (xi) performed such other analyses as we have deemed
appropriate.
 
  Our review was based solely on the consideration received by the Company
from the issuance of Company common stock and subordinated debt to the
Purchaser pursuant to the Placement Agreement subject to the standstill
restrictions agreed to by the Company and the Purchaser, which limit the
ability of the Purchaser and affiliates to acquire majority ownership of the
Company or to elect a majority of the Board of Directors, for an agreed period
of time and under the conditions set forth in the amended standstill
agreement. In rendering our opinion, it is our understanding, based upon
discussions with senior management of the Company and our review of the
related documents, that the Purchaser will not acquire control of the
management and direction of the business and affairs of the Company as a
result of the Investment.
 
  Further, with your permission and without independent investigation, we
assumed that the consideration to be paid by the Company in connection with
the Baxter Asset Purchase is fair to the Company and its shareholders from a
financial point of view. We have considered the view of the Board of Directors
and senior management of the Company that the proposed Baxter Asset Purchase
represents a significant business opportunity for the Company and that
significant strategic and operational benefits will be derived by consummating
the Baxter Asset Purchase and the concurrent investment and commercial
arrangements with the Purchaser. We also understand that the senior management
of the Company is of the view that the Investment represents the best source
of financing for the Baxter Asset Purchase available to the Company at this
time and that the Investment will provide significant benefit to the Company
by its assistance in obtaining necessary bank financing to consummate the
Baxter Asset Purchase.
 
  In arriving at our opinion, we were not authorized to solicit, and we did
not solicit, inquiries with respect to the placement of common stock or
subordinated debt of the Company with institutional investors in order to
finance in part the Company's Baxter Asset Purchase.
 
  In rendering our opinion, we have relied without independent verification on
the accuracy, completeness and fair presentation of all financial and other
information that was provided to us by the Company or was publicly available,
and this opinion is conditioned on such information being complete and
accurate in all material respects. With respect to the Company's financial
forecasts provided to us by management, including pro forma financial data
taking into account the Baxter Asset Purchase, we are assuming for the
purposes of our opinion that they have been reasonably prepared on bases
reflecting the best available estimates and judgments of the Company's
management at the time of preparation as to the future financial performance
of the Company. We have not made an independent evaluation or appraisal of the
assets (contingent or otherwise) of the Company nor have we been furnished
with any such evaluations or appraisals. We have not made any independent
evaluation of the solvency of the Company, and have assumed, with your
permission, that after giving effect to the Baxter Asset Purchase and related
debt and equity financing, including the Investment that: (i) the Company will
be able to pay its debts as they become due in the usual course of business;
(ii) the fair value of the Company's total assets would not be less than the
Company's total liabilities; and (iii) the Company will not have unreasonably
small capital with which to engage in its business. Further, our opinion is
based on economic, monetary and market conditions existing as of the date of
this opinion.
 
  Based on the foregoing, we are of the opinion on the date hereof that, in
light of the perceived benefits of consummating the Baxter Asset Purchase and
the necessity of obtaining financing
 
                                      I-2
<PAGE>
 
therefor, the consideration to be received by the Company from the Investment
in its subordinated debt and common stock by the Purchaser pursuant to the
Placement Agreement is fair, from a financial point of view, to the Company
and the shareholders of the Company other than the Purchaser and affiliated
corporations. In rendering our opinion, we are expressing no opinion as to the
price or trading range at which the common stock of the Company will trade or
the ability of the Company to access the capital markets prior to or
subsequent to the consummation of the Baxter Asset Purchase and the
Investment.
 
Very truly yours,

 COMPLIANCE WITH 1933 ACT; RESTRICTIONS ON TRANSFERABILITY OF PURCHASED SHARES
                             AND DEBENTURE SHARES
 
  10.1 Compliance with 1933 Act. The Purchased Shares, the Debenture and the
Debenture Shares shall not be transferable, except upon the conditions
specified in this Article and in the Standstill Agreement, as amended, which
conditions are intended among other things to insure compliance with the
provisions of the 1933 Act and applicable state securities laws in respect of
any such transfer.
 
  10.2 Restrictive Legend. Each certificate representing the Purchased Shares
or Debenture Shares shall (unless otherwise permitted by the provisions of
Section 10.4 below) be stamped or otherwise imprinted with the following
legend:
 
     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY APPLICABLE STATE SECURITIES LAW AND ARE SUBJECT TO THE
     RESTRICTIONS ON DISPOSITION SET FORTH IN AND TO THE OTHER
     PROVISIONS OF A COMMON SHARE AND DEBENTURE PURCHASE AGREEMENT,
     DATED MAY 24, 1995, BETWEEN VWR CORPORATION AND EM INDUSTRIES,
     INCORPORATED, AND A STANDSTILL AGREEMENT, DATED FEBRUARY 27,
     1995, AS AMENDED ON MAY 24, 1995, BETWEEN VWR CORPORATION AND
     EM INDUSTRIES, INCORPORATED. COPIES OF SUCH AGREEMENTS ARE ON
     FILE AT THE RESPECTIVE OFFICES OF VWR CORPORATION AND EM
     INDUSTRIES, INCORPORATED."
 
  10.3 Restrictions on Transferability. The Company shall not be required to
register the transfer of the Purchased Shares or the Debenture Shares on the
books of the Company unless the Company shall have been provided with an
opinion of counsel reasonably satisfactory to it prior to such transfer to the
effect that registration under the 1933 Act or any applicable state securities
law is not required in connection with the transaction resulting in such
transfer; provided, however, that no such opinion of counsel shall be
necessary in order to effectuate a transfer of Purchased Share or Debenture
Shares in accordance with the provisions of Rule 144(k) promulgated under the
1933 Act. Each certificate for Purchased Shares or Debenture Shares issued
upon any transfer as above provided shall bear the restrictive legend set
forth in Section 10.2 above, except that such restrictive legend shall not be
required if the opinion of counsel reasonably satisfactory to the Company
referred to above is to the further effect that such legend is not required in
order to establish compliance with the provisions of the 1933 Act and any
applicable state securities law, or if the transfer is made in accordance with
the provisions of Rule 144(k) under the 1933 Act.
 
  10.4 Termination of Restrictions on Transferability. The conditions
precedent imposed by this Article upon the transferability of the Purchased
Shares and Debenture Shares shall cease and terminate as to any of the
Purchased Shares or Debenture Shares when (i) such securities shall have been
registered under the 1933 Act and sold or otherwise disposed of in accordance
 
                                     II-14
<PAGE>
 
with the intended method of disposition by the seller or sellers thereof set
forth in the registration statement covering such securities, (ii) at such
times as an opinion of counsel reasonably satisfactory to the Company shall
have been rendered as required pursuant to Section 10.3 to the effect that the
restrictive legend on such securities is no longer required, or (iii) when
such securities are transferable in accordance with the provisions of Rule
144(k) promulgated under the 1933 Act. Whenever the conditions imposed by this
Article shall terminate as hereinabove provided with respect to any of the
Purchased Shares or Debenture Shares, the holder of any such securities
bearing the legend set forth in this Article as to which such conditions shall
have terminated shall be entitled to receive from the Company, without expense
(except for the payment of any applicable transfer tax) and as expeditiously
as possible, new stock certificates not bearing the portion of such legend
relating to the 1933 Act.

                      SURVIVAL OF COVENANTS, AGREEMENTS, 
                        REPRESENTATIONS AND WARRANTIES
 
  All covenants, agreements, representations and warranties made herein shall
survive until July 1, 1997; provided, however, representations and warranties
made herein shall only be deemed to have been made as of the date hereof and
as of the Closing Date.
 
                                  ARTICLE 12.
 
                                INDEMNIFICATION
 
  (a) Effective at the Closing, the Company agrees to indemnify, hold harmless
and defend the Purchaser and its Affiliates, against and in respect of any and
all claims, demands, liabilities, losses, costs and expenses (including
reasonable attorneys' fees and litigation expenses) arising out of or based
upon (i) the breach of any representation or warranty made by the Company in
this Agreement, the Standstill Agreement, as amended, or in any certificate or
other document required to be delivered pursuant hereto, or (ii) the breach by
the Company of any agreement or covenant contained in this Agreement or the
Standstill Agreement, as amended.
 
  (b) Effective at the Closing, the Purchaser agrees to indemnify, hold
harmless and defend the Company and its Affiliates against and in respect of
any and all claims, demands, liabilities, losses, costs and expenses
(including reasonable attorneys' fees and litigation expenses) arising out of
or based upon (i) the breach of any representation or warranty made by the
Purchaser in this Agreement, the Standstill Agreement, as amended, or in any
certificate or other document required to be delivered pursuant hereto, or
(ii) the breach by the Purchaser of any agreement or covenant contained in
this Agreement or the Standstill Agreement, as amended.
 
  (c) No party shall be liable for indemnification under this Article unless
the total of all liabilities, costs, losses and expenses for which the
indemnified party has a right to indemnification under this Article
(collectively, the "Indemnifiable Damages") exceeds $500,000, in which event
the indemnified party shall be entitled to Indemnifiable Damages solely in
excess of such amount.
 
  (d) No claims for indemnification under this Article may be made later than
July 1, 1997, with respect to the inaccuracy or breach of a representation or
warranty, or two (2) years after such breach first occurred with respect to
the breach of a covenant or agreement. No provision of this Agreement shall
limit the ability of either party to obtain specific performance of the other
 
                                     II-15
<PAGE>
 
party's obligations hereunder, including, without limitation, the obligations
of the Company to register the registrable securities.
 
  (e) The party seeking indemnification under this Article (the "Indemnified
Party") agrees to give prompt notice to the party against whom indemnity is
sought (the "Indemnifying Party") of the assertion of any claim, or the
commencement of any suit, action or proceeding, in respect of which indemnity
may be sought under such Article. The Indemnifying Party may participate in
and, at its election, control the defense of any such suit, action or
proceeding at its own expense; provided that counsel selected to conduct such
defense is reasonably satisfactory to the Indemnified Party. The Indemnifying
Party shall not be liable under this Article in the event prompt notice of the
assertion of a claim or the commencement of a suit, action or proceeding in
respect of which indemnity is sought is not given as described herein, but
only to the extent the defense of such claim, suit, action or proceeding is
prejudiced thereby, or for any settlement effected without its consent of any
claim, litigation or proceeding in respect of which indemnity may be sought
hereunder. The Indemnifying Party may settle or compromise any claim without
the prior written consent of the Indemnified Party; provided that the
Indemnifying Party may not agree to any such settlement pursuant to which any
remedy or relief, other than monetary damages for which the Indemnifying Party
shall be responsible hereunder, shall be applied to or against the Indemnified
Party, without the prior written consent of the Indemnified Party.

  of notice of such breach;
 
    (c) by either the Company or the Purchaser if the Closing shall not have
  occurred on or before November 1, 1995 unless the failure to close by such
  time is due to the breach of this Agreement by the party seeking to
  terminate.
 
  13.2 Effect of Termination. In the event of termination of this Agreement by
either the Company or the Purchaser as provided in Section 13.1, this
Agreement shall forthwith become void. No termination of this Agreement shall

written consent of the Purchaser, and the Purchaser may not assign its rights
or delegate its duties and obligations under this Agreement without the prior
written consent of the Company and, in the absence of such consent, any such
purported assignment or delegation shall be void; provided, however, that the
Purchaser may assign its rights and delegate its duties and obligations under
this Agreement and the Debenture without such consent to an Affiliate of the
Purchaser, which Affiliate (referred to herein as the "Assignee") may,
following duly authorized execution and delivery of an agreement assuming the
obligations of the Purchaser hereunder reasonably satisfactory to the Company,

                             STANDSTILL AGREEMENT
 
  THIS STANDSTILL AGREEMENT (the "Agreement") is made this 27th day of
February, 1995, by and between VWR CORPORATION, a Pennsylvania corporation
("Company") and EM Industries, Incorporated, a New York corporation ("EMI").
 
                                   RECITALS
 
  A. Company and EMI have entered into a Common Share and Warrant Purchase
Agreement pursuant to which, among other things, Company shall issue and sell
to EMI Common Stock (as defined below) of Company and a common share purchase
warrant (the "Warrant").
 
  B. The parties seek to regulate the acquisition and disposition by Purchaser
(as defined below) of Company's Voting Securities, provide for EMI
representation on Company's Board, and generally foster a constructive and
mutually beneficial relationship.
 
  C. EMI and Company acknowledge that Company has made, prior to the date
hereof, a careful evaluation of Purchaser's investment objectives with regard
to its ownership of Voting Securities, and the compatibility of Purchaser's
management and objectives with the management and objectives of Company; that
such factors were critical to Company in its decision to enter into this
Agreement; that, absent the provisions of Articles 2 through 4 hereof,
Purchaser's ownership of Voting Securities would present an unusual
opportunity for it to gain effective control of Company and Company might have
reached a different decision with regard to entering into this Agreement and
the Common Share and Warrant Purchase Agreement; that, therefore, the
provisions of Articles 2 through 4 were a material inducement to Company to
enter into this Agreement and the Common Share and Warrant Purchase Agreement;
and, that the primary purposes of Articles 2 through 4 are that, so long as
such provisions remain in effect and except as permitted by such provisions,
the Voting Securities owned by Purchaser not come to rest in the hands of any
single holder or group of holders other than Purchaser, and Purchaser's
ownership of Voting Securities not be increased, other than as provided for in
this Agreement or with the consent of Company. EMI acknowledges that such
purposes are reasonable and that the provisions of Articles 2 through 4 are
reasonable in view of such purposes.
 
  NOW, THEREFORE, in consideration of the mutual agreements and covenants set
forth herein and in the Common Share and Warrant Purchase Agreement, and for
other good and valuable consideration, the parties agree as follows:
 
                                  ARTICLE 1.

                                  ARTICLE 2.
 
         RESTRICTIONS ON ACQUISITION OF ADDITIONAL SHARES BY PURCHASER
 
  2.1 No Purchases Before Effective Date. Except as provided in Section 2.7,
Purchaser shall not, between the date of execution of this Agreement and the
Effective Date, acquire in any way or hold record or beneficial ownership of
any Voting Securities.
 
  2.2 No Purchases Beyond Percentage Limitation. Except as otherwise permitted
herein, Purchaser shall not, directly or indirectly, acquire any Voting
Securities beyond its "Percentage Limitation." The "Percentage Limitation"
shall be 20.1% of the Common Stock Equivalents.
 
  2.3 Permitted Purchase Due to Increases in Common Stock Equivalents. If the
Common Stock Equivalents increase at any time and, as a consequence thereof
Purchaser's aggregate ownership of Common Stock Equivalents falls below the
Percentage Limitation, Purchaser may acquire additional shares of Common Stock
up to the Percentage Limitation, as follows:
 
    (a) Purchaser may at any time do so by open-market purchases, partial
  tender offer, or private transaction; and/or
 
    (b) Purchaser may, in accordance with Section 2.4, purchase unissued or
  treasury shares of Common Stock from Company.
 
  2.4 Procedures Concerning Purchaser's Acquisition of Shares From Company in
Response to Increases in Common Stock Equivalents.
 
    (a) Within thirty (30) days after any increase in Common Stock
  Equivalents (other than an increase previously notified to EMI under
  Section 2.6), Company shall give EMI written notice setting forth the
  number of Common Stock Equivalents prior to the increase, the number of
  Common Stock Equivalents after the increase, Purchaser's Percentage
  Limitation, the number of shares of Common Stock Purchaser may purchase as
  a consequence of said increase, and the per share purchase price for such
  shares.
 
    (b) The purchase price per share of Common Stock purchased under Section
  2.3(b) shall be established as follows:
 
      (i) if the Common Stock Equivalents increased as a result of issuance
    by Company of one or more Voting Securities (other than issuance of
    options under Company's stock option plans), the price per share shall
    be the lesser of the Twenty Day Average or the aggregate fair market
    value of all consideration received by Company for such Voting
    Securities determined in good faith by the Board (including attributing
    the consideration received with respect to each Voting Security other
    than Common Stock) within thirty (30) days after the issuance, divided
    by the number of Common Stock Equivalents issued by Company; or
 
      (ii) if the Common Stock Equivalents increased as a result of
    Company's issuance of stock options under Company's stock option plans,
    the purchase price shall be the exercise price of such stock options.
 
    (c) Purchaser shall have the right to purchase from Company a number of
  shares of Common Stock equal to its Percentage Limitation multiplied by the
  increase in the Common Stock Equivalents. Purchaser shall have sixty (60)
  days from receipt of Company's notice pursuant to Section 2.4.(a) above to
  notify Company in writing whether it elects to purchase any of such shares
  of Common Stock and, if it so elects, the number of shares it elects to
  purchase. At the time Purchaser delivers its notice to Company, there shall
  be a binding agreement between Purchaser and Company for the purchase and
  sale of the number of shares of Common Stock elected by Purchaser.
  Purchaser shall pay the purchase price to Company in immediately available
  funds, and Company shall deliver certificates representing
 
                                     III-4
<PAGE>
 
  the shares to Purchaser, on a date specified by Purchaser in its notice,
  which date shall not be more than ten (10) days after Purchaser delivers
  its notice to Company.
 
  2.5 Limitation on Purchaser's Right to Purchase Common Stock Pursuant to
Section 2.3 in the Event of a Business Acquisition by Company.
 
    (a) Notwithstanding Section 2.3, Purchaser shall have no right to
  purchase additional shares of Common Stock if (i) the Common Stock
  Equivalents increased due to issuance by Company of Voting Securities in
  connection with Company's acquisition of a business entity from a third
  party, (ii) during the one year period following closing of such an
  acquisition, Company repurchases a number of shares of Voting Securities
  equal to or greater than the number of shares of Common Stock Equivalents
  issued to the third party, and (iii) Company's Plan to repurchase shares
  was approved by a majority of the Board and notice thereof was given to
  Purchaser prior to the closing of the acquisition. If Company does not
  within the one year period repurchase a number of shares of Voting
  Securities equal to the number of Common Stock Equivalents issued to the
  third party, Purchaser shall have all rights under Section 2.3 to purchase
  shares of Common Stock up to its Percentage Limitation. For purposes of
  Section 2.4, Company shall give notice to Purchaser in accordance with
  Section 2.4(a) within thirty (30) days after the end of the one year
  period, and the purchase price to be paid by Purchaser to purchase shares
  from Company shall be established in accordance with Section 2.4(b)(i) as
  of the date of the closing of the business acquisition. Except as modified
  by the preceding sentence, the provisions of Section 2.4 shall govern any
  such purchase.
 
    (b) The limitation contained in Section 2.5(a) shall only apply to
  increases of fifteen percent (15%) or less in the Common Stock Equivalents.
  If in connection with an acquisition Company issues Voting Securities which
  cause the Common Stock Equivalents to increase more than fifteen percent
  (15%), Purchaser shall have all rights under Section 2.3 to purchase Common
  Stock in connection with such increase over fifteen percent (15%).
 
  2.6 Permitted Purchase If Company Proposes to Issue Voting Securities for
Cash. If Company proposes to issue Voting Securities solely for cash pursuant
to a registered offering or a private placement, and as a consequence thereof
Purchaser's aggregate ownership of Common Stock Equivalents would fall below
its Percentage Limitation, Company shall give EMI written notice of such fact
(the "Notice of Issue") at least thirty (30) days prior to the anticipated
date of such issuance stating the anticipated number of Common Stock
Equivalents to be issued and the anticipated price per Common Stock
Equivalent. Purchaser shall have the right to purchase from Company the number
of shares of Common Stock required for Purchaser to own in the aggregate the
Percentage Limitation of the Common Stock Equivalents following the issuance
of the shares actually issued in such registered offering or private
placement. Purchaser shall have fifteen (15) days from receipt of the Notice
of Issue to notify Company in writing whether it elects to purchase any of
such shares of Common Stock and, if it so elects, the number of shares it
elects to purchase. At the time Purchaser delivers its election to Company,
there shall be a binding agreement between Purchaser and Company for the
purchase and sale of the number of shares of Common Stock elected by
Purchaser, subject to the consummation of such sale described in the Notice of
Issue. The purchase price per share shall be the price per Common Stock
Equivalent at which the Voting Securities are actually issued by Company;
provided, however, that without Purchaser's consent the purchase price shall
not be more than one hundred twenty percent (120%) of the anticipated price
per Common Stock Equivalent set forth in the Notice of Issue. Purchaser shall
pay the purchase price to Company in immediately available funds, and Company
shall deliver certificates representing the shares of Common Stock to
Purchaser, on the date of Company's issuance of the Voting Securities.

  2.7 Permitted Purchase in Response To Third Party Tender Offer or Exchange
Offer.
 
    (a) If a tender or exchange offer is made by any Person or 13D Group
  (other than Purchaser or any Person acting in concert with Purchaser) to
  acquire Voting Securities, Purchaser may make a tender offer for up to an
  equivalent number of shares of such Voting Securities as are sought to be
  purchased by the party making the other tender offer. If Purchaser
  initiates a tender offer under this Section 2.7, the tender offer may be on
  such terms as Purchaser shall elect and Company agrees that it shall not in
  any way (whether by active opposition, Board announcement or otherwise)
  contest said tender offer.
 
    (b) If, following such a tender offer by Purchaser, it owns in the
  aggregate more than the Percentage Limitation of the Common Stock
  Equivalents, Company shall have the right, exercisable at any time during
  the six month period following completion of Purchaser's tender offer, to
  demand the purchase from Purchaser a number of shares of such Voting
  Securities as will cause Purchaser to own in the aggregate the Percentage
  Limitation of the Common Stock Equivalents following such purchase;
  provided, however, that Purchaser shall not be obligated to sell any Common
  Stock Equivalents to Company pursuant to this Section 2.7 until such time
  as such sale would not subject Purchaser to liability under Section 16(b)
  of the Exchange Act or any other applicable provision of federal or state
  law; and, provided further, that Purchaser shall not be entitled to vote
  such Common Stock Equivalents between the time of Company's demand to
  purchase pursuant to this Section 2.7(b) and Purchaser's sale of such
  Common Stock Equivalents. Company shall, within said six month period,
  notify EMI in writing whether it elects to purchase any of such shares and,
  if it so elects, the number of shares it elects to purchase. At the time
  Company delivers its notice to EMI, there shall be a binding agreement
  between Purchaser and Company for the purchase and sale of the number of
  shares of such Voting Securities elected by Company.
 
    (c) The purchase price per share shall be the price per share paid by
  Purchaser in such tender offer to the tendering shareholders. In addition,
  Company shall reimburse Purchaser for Purchaser's pro-rata share of the
  costs and expenses incurred in conducting said tender offer. The pro-rata
  share of costs and expenses shall be the aggregate of all costs and
  expenses (including Purchaser's cost of borrowing, not to exceed the lesser
  of the prime interest rate plus 1% and Company's then-current cost of
  borrowing) actually incurred by Purchaser, divided by the number of shares
  of Voting Securities acquired by it in the tender offer. Company shall pay
  the purchase price and the costs and expenses described in this paragraph
  to Purchaser in immediately available funds, and Purchaser shall deliver
  certificates representing the shares to Company, on a date specified by
  Company in its notice, which date shall not be more than twenty (20) days
  after Company delivers its notice to EMI.
 
    (d) If Company's purchase is subject to or is voluntarily submitted for
  shareholder approval, Purchaser shall vote all its Voting Securities in
  favor of the purchase.
 
    (e) If Company does not elect to purchase shares from Purchaser, or
  elects to purchase only a portion of the shares under Section 2.7(b),
  Purchaser shall be entitled to retain the shares over the Percentage
  Limitation but the Percentage Limitation shall remain 20.1%.
 
  2.8 Permitted Purchase With Board Approval. Notwithstanding any other
provision of this Agreement, Purchaser may purchase additional shares of
Voting Securities at any time, if two-thirds ( 2/3) of the Unaffiliated
Directors approve such purchase in advance.
 
  2.9 Permitted Purchase by 100% Tender Offer After Four
Years. Notwithstanding any other provision of this Agreement, commencing on
the fourth anniversary of the Effective Date, Purchaser shall have the right
to acquire additional shares of Common Stock by means of a tender offer in
accordance with Section 2.10 below.
 
                                     III-6

  2.10 Requirements for Tender Offers.
 
    (a) Whenever Purchaser shall make a tender offer for shares of Common
  Stock under Section 2.9, Purchaser may not close the acquisition of the
  tendered shares unless all of the following requirements have been
  satisfied:
 
      (i)  Purchaser's offer shall have been made to all holders of Common
    Stock;
 
      (ii)  Purchaser shall offer to purchase for cash all shares tendered;
    and
 
      (iii) Purchaser's offer shall have been accepted by shareholders
    owning not less than two-thirds ( 2/3) of the outstanding Common Stock.
 
    (b) With respect to calculating whether Purchaser's offer has been
  accepted by shareholders owning two-thirds ( 2/3) of the outstanding Common
  Stock, Common Shares beneficially owned by Purchaser shall be excluded from
  the outstanding Common Stock.
 
  2.11 Mandatory Disposal of Excess Shares. If in violation of any provision
of this Article 2 Purchaser shall at any time hold in the aggregate in excess
of its then Permitted Percentage, Purchaser shall be required to dispose of
such excess shares by promptly selling, subject to Company's right of first
refusal under Section 3.7, sufficient Voting Securities so that after such
sale Purchaser shall own in the aggregate not more than its then Permitted
Percentage, provided, however, that Purchaser shall not be obligated to sell
any Voting Securities to Company pursuant to this Section 2.11 until such time
as such sale would not subject Purchaser to liability under Section 16(b) of
the Exchange Act or any other applicable provision of federal or state law;
and, provided further, that Purchaser shall not be entitled to vote such
Voting Securities between the time of Company's demand that Purchaser dispose
of such Voting Securities pursuant to this Section 2.11 and Purchaser's
disposal of such Voting Securities. If Purchaser fails to dispose of shares of
Voting Securities within one hundred eighty (180) days after receipt of notice
from Company advising EMI of its obligation so to dispose of shares (it being
understood that giving of notice by Company is not a precondition to
Purchaser's obligation to dispose of excess shares), Company shall have the
right to redeem at par value from Purchaser a number of shares of Common Stock
so that after such redemption the shares of Voting Securities owned by
Purchaser do not exceed Purchaser's then Permitted Percentage. Any Voting
Securities held by Purchaser in contravention of this Section 2.11 may not be
voted in any manner on which shareholders of Company are entitled to vote and
Company shall not be required to count any such votes, if cast, in determining
the result of shareholder voting on any matter.
 
  2.12 Monthly Report of Ownership. During the term of this Agreement,
Purchaser will furnish to Company, within ten (10) days after the end of each
calendar month in which Purchaser acquires or disposes of any Voting
Securities, a statement showing the number of shares of Voting Securities
acquired or disposed of during the just ended month and the aggregate number
of shares of Voting Securities held by Purchaser at the end of such month. To
the extent that any such acquisition or disposition must be reported to the
Commission, Purchaser may fulfill the statement requirement in this Section
2.12 by providing to Company a copy of such report to the Commission.
 
  2.13 General Rule Regarding Acquisition of Voting Securities. Purchaser
agrees that any and all acquisitions of Voting Securities shall be made in
compliance with all applicable federal and state securities laws. EMI agrees
to indemnify, defend and hold harmless Company, its officers, directors and
employees from and against any and all losses, claims, liabilities, assertions
and expenses incurred or suffered by any of them, including attorneys' fees
and costs of litigation, as a consequence of a claim by any party other than
Company or any of its Affiliates that Purchaser breached its obligations set
forth in the preceding sentence.

  2.14 Requirements of Trading Exchange or Stock Quotation System.
 
  Notwithstanding any other provision of this Agreement, if, by reason of the
listing or other requirements of the principal trading exchange or national
automated stock quotation system on which the Company's Common Stock is then
traded or quoted, the issuance by Company of any additional Voting Securities
to Purchaser pursuant to this Article 2 requires approval of Company's
shareholders, then Company's obligation to issue and sell such additional
Voting Securities to Purchaser shall be subject to receipt of such shareholder
approval, which Company shall use its best efforts to obtain as soon as
possible after the date on which Purchaser shall otherwise become entitled to
purchase such additional Voting Securities from Company pursuant to this
Article 2.
 
                                  ARTICLE 3.
 
 SALES OF SHARES BY PURCHASER AND RELATED RIGHTS AND OBLIGATIONS OF PURCHASER

provided that Purchaser shall notify Company at least two Business Days prior
to the date of entering any sale or transfer order of Common Stock pursuant to
Rule 144, and provided further that, if Company shall thereupon notify EMI of
the pendency of its public offering of any Voting Securities, Purchaser shall
not effect any sales under Rule 144 within 10 days prior to the commencement
of or during such offering.
 
  3.4 Allowed Private Sales to Third Parties or Pursuant to Tender
Offer. Subject to Company's right of first refusal under Section 3.7,

  3.5 Allowed Transfers by EMI and Purchaser Affiliates. EMI and Purchaser
Affiliates may at any time transfer Voting Securities among themselves,

responsibilities of EMI to Company, provided that the transferee shall agree
in advance in writing to be bound by the terms of this Agreement.
 
  3.6 Allowed Transfers Upon Approved Business Disposition. Purchaser may
dispose of Voting Securities in conjunction with a merger or consolidation in

3.2, 3.3 or 3.4, Company shall have a right of first refusal to purchase said
Voting Securities in accordance with the procedures set forth in Section 3.8
below.
 
                                     III-8

  3.8 Procedures for Right of First Refusal.
 
    (a) If Purchaser desires to sell a third party all or part of its Voting
  Securities pursuant to Section 3.4 above ("Private Sale"), or if Purchaser
  desires to sell all or part of its Common Stock in the open market pursuant
  to Section 3.2 or 3.3 above ("Market Disposition Program"), Purchaser shall
  transmit to Company a written notice ("Notice of Proposed Sale") setting
  forth:
 
      (i)   if a Private Sale, (A) as to each Person to whom such sale is
    proposed to be made: (1) the name, address and principal business
    activity of such Person; (2) the number of shares of Voting Securities
    proposed to be sold to such Person; (3) the manner in which the sale is
    proposed to be made; and (4) the price at which or other consideration
    for which, and the material terms upon which, such sale is proposed to
    be made, and (B) representing that the Private Sale is bona fide; and
 
      (ii)  if sales pursuant to a Market Disposition Program: (A) the
    approximate date the sales are scheduled to commence; and (B) the
    amount of Common Stock sought to be disposed of.
 
    (b) Upon receipt of the Notice of Proposed Sale Company shall have an
  option to purchase, in the case of a Private Sale, all but not less than
  all of the Voting Securities proposed to be sold, and in the case of a
  Market Disposition Program, all, if the Market Disposition Program is a
  firm commitment public offering, or, if it is not such an offering, any
  part, of the Common Stock proposed to be disposed of, on the following
  terms and conditions;
 
      (i)   If the option arises in connection with a Private Sale, the
    purchase price shall be the price specified in the Notice of Proposed
    Sale.
 
      (ii)  If the option arises in connection with a Market Disposition
    Program, the purchase price per share of Common Stock shall be the
    Twenty Day Average determined as if the day Purchaser delivers the
    Notice of Proposed Sale to Company is the closing date of an issuance
    of securities by Company in the absence of any public announcement.
 
      (iii) If a majority of the Unaffiliated Directors determine to
    exercise the option, they shall direct Company to send a written notice
    (the "Notice of Exercise") to EMI within thirty (30) days after the
    Notice of Proposed Sale is received by Company specifying the number of
    shares Company is purchasing; provided, however, that in the case of a
    tender offer or exchange offer, EMI must receive the Notice of Exercise
    not less than forty-eight (48) hours prior to the earlier of (A) the
    expiration of the tender offer or exchange offer or (B) any date after
    which shares tendered may be treated less favorably than shares
    tendered prior thereto. If approval of such purchase by Company's
    shareholders is required by law or Company's Restated Articles of
    Incorporation, and if the Private Sale is in response to a tender
    offer, Company shall waive its right of first refusal granted under
    Section 3.7; otherwise, Company's Notice of Exercise shall be subject
    to receipt of such shareholder approval, which Company shall use its
    best efforts to obtain as soon as possible, and in any event within one
    hundred twenty (120) days after, the date of the Notice of Exercise.
    Company's failure to obtain shareholder approval within the one hundred
    twenty (120) day period shall give Purchaser the right to proceed with
    the proposed sale under Section 3.8(c). If such repurchase is subject
    to shareholder approval, Purchaser shall vote all its Voting Securities
    in favor of the purchase.
 
      (iv)  Upon EMI's receipt of the Notice of Exercise, there shall be a
    binding agreement between Purchaser and Company for the purchase and
    sale of the number of shares contained in the Notice of Exercise. The
    closing of the purchase and sale shall occur on the thirtieth Business
    Day following EMI's receipt of the Notice of Exercise. At the closing
    Purchaser will deliver to Company certificates for the Voting
    Securities to be sold,
 
                                     III-9
<PAGE>
 
    duly endorsed for transfer or accompanied by a duly executed stock
    power, and Company will deliver to Purchaser the purchase price as
    follows: if Company's purchase is following Purchaser's proposed
    Private Sale, Company shall pay Purchaser the price specified in the
    Notice of Proposed Sale in the same manner (and the sale shall be upon
    the same terms) specified therein, and if Company's purchase is
    following Purchaser's proposed Market Disposition Program, Company
    shall pay Purchaser at the closing for the shares purchased in
    immediately available funds; provided, however, that if Company
    receives a Notice of Proposed Sale on or before the third anniversary
    of the Effective Date, Company shall have the option to pay Purchaser
    by delivery at the closing of ten (10%) percent of the purchase price
    in immediately available funds, and the balance by delivery of a
    promissory note providing terms specified in the next succeeding
    sentence; provided, further, that notwithstanding the preceding
    proviso, if the Notice of Proposed Sale received by Company on or
    before the third anniversary describes a proposed Private Sale in
    response to a tender offer, Company shall pay the purchase price in the
    same manner (and the sale shall be upon the same terms) specified in
    the Notice of Proposed Sale. The promissory note shall provide for:
    fixed interest at a rate equal to the Company's then-current cost of
    borrowing; equal annual installments including interest payable on each
    anniversary of the closing in immediately available funds, with each
    installment in an amount sufficient to amortize the promissory note in
    ten annual payments; and for the entire unpaid balance including
    accrued and unpaid interest to be payable on the fifth anniversary of
    the closing.
 
      (v) Company may assign its right to purchase the Voting Securities
    and may designate in the Notice of Exercise one or more Persons to take
    title to all or any part of the Voting Securities, but this shall not
    relieve Company of its obligation to pay the purchase price.
 
    (c) If following receipt of a Notice of Proposed Sale Company fails to
  give EMI a Notice of Exercise within the prescribed time period, Purchaser
  shall be free to effect such sale on the following terms and conditions:
 
      (i)  if a Private Sale was proposed, Purchaser may effect such sale at
    any time during the period ending one hundred twenty (120) days after
    the date Company's Notice of Exercise was required to be given, to the
    Person or Persons specified in the Notice of Proposed Sale for the
    consideration and on the terms specified in said notice; and
 
      (ii) if a Market Disposition Program was proposed, Purchaser may
    effect such sales at any time during the period ending one hundred
    eighty (180) days after the date Company's Notice of Exercise required
    to be given.
 
    (d) If Purchaser does not make the sales within the time periods provided
  above, the Voting Securities so proposed to be sold will once again become
  subject to this Agreement to the same extent as if such sales had not been
  proposed.
 
  3.9 Purchaser's Covenants With Respect to Distribution of Shares. In any
transaction or transactions under Section 3.2 or 3.3, Purchaser shall use its
reasonable best efforts, and shall cause any underwriter involved to use its
reasonable best efforts, to sell the Common Stock in the United States and in
a manner which will effect the broadest distribution reasonably possible, with
no sales to any one person or group (as defined in the Exchange Act) in excess
of 10% of the Common Stock sold in such sale.
 
  3.10 Company's Undertaking to Cooperate in Rule 144 Transactions. In the
event of any proposed sales of Common Stock by Purchaser under Section 3.3,
Company shall cooperate with Purchaser to enable such sales to be made in
accordance with applicable laws, rules and regulations, the requirements of
Company's transfer agent, and the reasonable requirements of
 
                                    III-10

the broker through which the sales are proposed to be executed, and shall,
upon request, furnish unlegended certificates representing Common Stock in
such numbers and denominations as Purchaser shall reasonably require for
delivery in connection with such sales.

  4.1 Placement of Legends and Entry of Stop Transfer Orders. Purchaser
agrees:
 
    (a) that, within ten (10) Business Days after its acquisition of any
  certificates evidencing Voting Securities (or, in the case of Voting
  Securities currently owned by Purchaser, within ten (10) Business Days
  after the date hereof) to submit such certificates to Company for placing
  on the face thereof the following legends:
 
     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     ANY APPLICABLE STATE SECURITIES LAW AND ARE SUBJECT TO THE
     RESTRICTIONS ON DISPOSITION SET FORTH IN AND TO THE OTHER
     PROVISIONS OF A COMMON SHARE AND WARRANTY PURCHASE AGREEMENT,
     DATED FEBRUARY 27, 1995, BETWEEN VWR CORPORATION AND EM
     INDUSTRIES, INCORPORATED, AND A STANDSTILL AGREEMENT, DATED
     FEBRUARY 27, 1995, BETWEEN VWR CORPORATION AND EM INDUSTRIES,
     INCORPORATED. COPIES OF SUCH AGREEMENTS ARE ON FILE AT THE
     RESPECTIVE OFFICES OF VWR CORPORATION AND EM INDUSTRIES
     INCORPORATED.";
 
  and such additional legends designed to ensure compliance with Federal and
  State laws as counsel for Company may reasonably request; and
 
    (b) to the entry of stop transfer orders with the transfer agents of any
  such Voting Securities, against the transfer of such legended certificates
  except in compliance with this Agreement.
 
  4.2 Removal of Legends and Stop Transfer Orders. Company agrees that it
will, upon receipt of an opinion from its counsel that it is appropriate so to
do and upon the presentation to its transfer agent of the certificates
containing the legends provided for in Section 4.1(a), remove such legends and
withdraw the stop transfer orders provided for in Section 4.1(b) with respect
to such certificates, upon the earlier of the following:
 
    (a) any sale of the shares represented by such certificates made under
  Section 3.2, 3.3, or 3.4; or
 
    (b) termination of this Agreement.
 
                                  ARTICLE 5.
 
                  CERTAIN AGREEMENTS OF PURCHASER AND COMPANY
 
  5.1 Future Actions. Purchaser shall not, unless the prior written consent of
the Board (in which a majority of the Unaffiliated Directors shall concur) has
been obtained, and then only to the extent express written consent has been
obtained:
 
    (a) at any time before the expiration of four (4) years after the
  Effective Date, solicit proxies or become a "participant" in a
  "solicitation" (as such terms are defined in Regulation
 
                                    III-11
<PAGE>
 
  14A under the Exchange Act) in opposition to the recommendation of the
  majority of the directors on the Board with respect to any matter; or
 
    (b) deposit any Voting Securities in a voting trust or subject them to a
  voting agreement or other arrangement of similar effect; provided, however,
  that nothing in this Section 5.1 shall preclude Purchaser from so
  depositing any Voting Securities if such trust, agreement or arrangement
  is, and continues to be during the term of this Agreement, solely by and
  among EMI and Purchaser Affiliates; or
 
    (c) join a partnership, limited partnership, syndicate or other group for
  the purpose of acquiring, holding or disposing of Voting Securities within
  the meaning of Section 13(d) of the Exchange Act; or
 
    (d) induce or attempt to induce any other Person to initiate a tender
  offer for any securities of Company, or to effect any change of control of
  Company, or take any action for the purpose of convening a stockholders'
  meeting of Company; or
 
    (e) acquire, by purchase or otherwise, more than 1% of any class of
  equity securities of any entity which, prior to the time Purchaser acquires
  more than 1% of such class, is publicly disclosed (by filing with the
  Commission or otherwise) to be the beneficial owner of more than 5% of any
  class of the Voting Securities; if Purchaser owns in the aggregate in
  excess of 1% of any such entity, it shall promptly divest such excess;
  provided, however, that Purchaser shall not be obligated to divest itself
  of such excess pursuant to this Section 5.1(e) until such time as such
  divestment would not subject Purchaser to liability under Section 16(b) of
  the Exchange Act or any other applicable provision of federal or state law;
  and, provided further, that Purchaser shall not be entitled to vote such
  Voting Securities until Purchaser shall divest itself of such excess; and,
  provided further, that upon being notified by Company in writing that an
  entity owns in excess of 5% of any class of the Voting Securities,
  Purchaser shall affirm in writing to Company that Purchaser does not own,
  in the aggregate, more than 1% of any class of equity securities of such
  Person.
 
  5.2 Acquisitions and Transfers in Contravention of
Agreement. Notwithstanding Company's rights to seek injunctions or other
relief, any Voting Securities acquired or transferred by Purchaser in
contravention of this Agreement may not be voted on any matter on which
shareholders of Company are entitled to vote, any attempt to vote such Voting
Securities shall be a breach of this Agreement and Company shall not be
required to count any such votes, if cast, in determining the result of
shareholder voting on any matter.
 
  5.3 Company's Issuance of Securities. During the term of this Agreement,
Company shall not issue any security (including without limitation any Voting
Security) which provides the holder(s) thereof with any extraordinary or
special voting rights or any right to veto any action of Company, unless such
issuance is approved in advance by an Affiliated Director. Further, Company
shall not consider or approve any such issuance prior to the Effective Date.
 
                                  ARTICLE 6.
 
                              BOARD OF DIRECTORS
 
  6.1 Size of Board. On or before the Effective Date, Company shall take all
requisite action to increase the size of the Board by two to eleven and to
appoint, effective as of the Effective Date, individuals designated by EMI to
fill the two new seats.
 
  6.2 Terms. EMI shall advise company on or before the Effective Date which of
the Affiliated Directors shall have a term expiring at the second annual
meeting of shareholders of Company next following the Effective Date, and
which shall have a term expiring at the third
 
                                    III-12
<PAGE>
 
such annual meeting. After the term of any Affiliated Director expires, his or
her successor shall serve a term of three (3) years as provided in the
Restated Articles of Incorporation of Company.
 
  6.3 Vacancies. In the event of the death, resignation, retirement,
disqualification or removal from office of any Affiliated Director for any
reason, EMI shall have the right to designate a replacement for such
Affiliated Director, or fill such vacancy, to the extent EMI would be entitled
to designate a nominee for election to the Board of Directors pursuant to
Section 6.4 hereof if directors were to be elected at an annual meeting
occurring at such date.
 
  6.4 Proportional Representation.
 
    (a) Company shall annually cause representatives designated by EMI to be
  nominated for election to the Board so as to provide Purchaser with that
  percentage representation on the Board, rounded down to the nearest whole
  number, as shall equal the Permitted Percentage applicable at the time of
  each annual nomination. With respect to committees of the Board, Purchaser
  shall be entitled to be represented on any committee with respect to which
  EMI requests representation.
 
    (b) Purchaser shall vote its shares of Common Stock so as to elect to the
  Board its proportionate number of Affiliated Directors and the persons who
  have been designated by the Unaffiliated Directors, and in all other
  matters so as to provide other Company shareholders with corresponding
  proportionate representation. If, pursuant to the Restated Articles of
  Incorporation of Company, cumulative voting for the election of Company
  directors is required, Purchaser may initially vote its shares to ensure
  that its then proportionate number of Affiliated Directors are elected.
  Purchaser agrees that, once its proportionate number of Affiliated
  Directors are elected, Purchaser shall vote its shares of Common Stock so
  as to elect persons to the Board who have been designated by the
  Unaffiliated Directors.
 
    (c) Subject to the provisions of Section 6.3, Company may effect changes
  in Board representation by increase in the size of the Board or by
  resignations or retirements of Board members. Notwithstanding the
  foregoing, Purchaser's right to proportional Board representation shall not
  cause the number of Affiliated Directors to (i) decrease during the one
  year period during which Company has the right to purchase Voting
  Securities under Section 2.5(a), or (ii) increase during the six month
  period during which Company has the right to purchase Voting Securities
  under Section 2.7(b).
 
                                  ARTICLE 7.
 
                              REGISTRATION RIGHTS
 
  7.1 Duration of Registration Rights. Purchaser's rights to have Company
register shares of Registrable Securities (as defined below) provided in this
Article 7 shall terminate upon the Restriction Termination Date (as defined
below). Rights of a Holder other than Purchaser to have Company register
shares of Registrable Securities provided in this Article 7 shall terminate
upon the Restriction Termination Date. As used in this Article 7, "Registrable
Securities" shall mean all Common Stock so long as certificates representing
the same are required to bear the restrictive legend set forth in Section 4.1
hereof, to the extent that such legend refers to registration under the Act.
As used in this Article 7, "Restriction Termination Date" shall mean, with
respect to any Registrable Securities, the earliest of (i) the date that such
Registrable Securities shall have been Registered and sold or otherwise
disposed of in accordance with the intended method of distribution by the
seller or sellers thereof set forth in the Registration Statement covering
such Registrable Securities or transferred in compliance with Rule 144 under
the Securities Act and (ii) the date that an opinion of counsel to Company,
which opinion of counsel shall be reasonably acceptable to Purchaser,
containing reasonable assumptions shall have been rendered and, based
 
                                    III-13
<PAGE>
 
upon such opinion, the legend referred to in Section 4.1 hereof, to the extent
that such legend refers to registration under the Act, shall have been
removed.
 
  7.2 Demand Registration Covenant.
 
    (a) If a Holder requests in writing that Company register under the Act
  any Registrable Securities then owned by Holder, Company will use its best
  efforts to cause the offering and sale to be registered as soon as
  reasonably practicable. In connection therewith Company shall prepare and
  file a registration statement under the Act on such form as Company shall
  determine to be appropriate; provided, however, that Company shall not be
  obligated to file more than one registration statement pursuant to this
  Section 7.2 during any 12-month period. The request shall specify the
  amount of Registrable Securities intended to be offered and sold, shall
  express Holder's present intent to offer such Registrable Securities for
  distribution, shall describe the nature or method of the proposed offer and
  sale, and shall contain the undertaking of Holder to comply with all
  applicable requirements of this Article 7.
 
    (b) Upon receipt of a request for registration under Section 7.2, Company
  will promptly give notice to all Holders other than those initiating the
  request and provide a reasonable opportunity for such Holders to
  participate in such registration. Any such other Holder must notify Company
  in writing of its desire to participate, within thirty (30) days of receipt
  of Company's notice.
 
    (c) Any request for registration under Section 7.2 must be for a firm
  commitment public offering to be managed by one or more Investment Banking
  Firms selected by the Holders requesting registration, provided that such
  Investment Banking Firms are reasonably satisfactory to Company. If, in the
  written opinion of the Investment Banking Firms marketing factors require a
  limitation of the number of shares to be underwritten, and if the total
  amount of securities that all Holders (initiating and non-initiating)
  request pursuant to Section 7.2 to be included in such offering exceeds the
  amount of securities that the Investment Banking Firms reasonably believe
  compatible with the success of the offering, Company shall only be required
  to include in the offering the amount of Registrable Securities that the
  Investment Banking Firms believe will not jeopardize the success of the
  offering, and such amount shall be allocated among such Holders in
  proportion to the respective amounts of Registrable Securities proposed to
  be sold by each of the Holders. Any shares of Registrable Securities that
  are so excluded from the underwriting shall be excluded from the
  registration.
 
    (d) Subject to the provisions of Section 7.2(a) and 7.2(b), if within
  forty-five (45) days after receipt of a request under Section 7.2(a) and
  any requests under Section 7.2(b), Company shall have obtained (i) from
  Commission a "no-action" letter, in form and substance reasonably
  satisfactory to the counsel of the Holders requesting registration, in
  which the Commission has indicated that it will take no action if, without
  registration under the Act, Holders dispose of the Registrable Securities
  covered by the request(s) in the manner proposed or (ii) any opinion of its
  counsel (concurred in by counsel for the requesting Holder(s)) that no
  registration under the Act is required, Company need not comply with such
  request or request(s); provided, however, that receipt of such "no-action"
  letter or opinion shall not constitute a registration for the purpose of
  determining Company's obligations to Holders under Section 7.2; and
  provided, further, that in such event counsel for Company shall opine that,
  whether by reason of the "no-action" letter or otherwise, the removal of
  any legend from certificates representing all shares to which such "no-
  action" letter or opinion refers is permissible, and, if so, Company shall
  remove from such certificates all legends no longer required and shall
  rescind any stop-transfer instructions previously communicated to its
  transfer agent relating to such certificates.
 
  7.3 Participation Registration Covenant. If Company shall propose
registration under the Act of an offering of Common Stock, Company shall give
prompt written notice of such fact to each
 
                                    III-14
<PAGE>
 
Holder and will use all reasonable efforts to cause the registration of such
number of shares of Common Stock then owned by Holders as Holders shall
request, within fifteen (15) days after receipt of such notice, to be
included, upon the same terms (including the method of distribution) of any
such offering; provided, however, that (a) Company shall not be required to
give notice or include such Common Stock in any such registration if the
proposed registration (i) is not a primary registration of securities by
Company for its own account, or (ii) is primarily (A) a registration of a
stock option or compensation plan or of securities issued or issuable pursuant
to any such plan, or (B) a registration of securities proposed to be issued in
exchange for securities or assets of, or in connection with a merger or
consolidation with, another corporation; (b) the offering of Common Stock by
Holders shall comply with Section 3.9 above; and (c) Company may, in its sole
discretion and without the consent of the Holders, withdraw such registration
statement and abandon the proposed offering.
 
  7.4 Company's Obligations in Connection with Registrations. In connection
with any registration of Registrable Securities undertaken by Company under
Article 7, Company shall:
 
    (a) furnish to Holders or their underwriter such copies of any prospectus
  (including any preliminary prospectus) Holders may reasonably request to
  effect the offering and sale, but only while Company is required under the
  provisions hereof to cause the registration statement to remain current and
  effective;
 
    (b) use its best efforts to qualify the offering under applicable Blue
  Sky or other state securities laws to enable Holders to offer and sell the
  Registrable Securities; provided, however, that Company shall not be
  obligated to qualify as a foreign corporation to do business under the laws
  of any jurisdiction in which it is not then qualified;
 
    (c) furnish Holders, at the expense of Company, with unlegended
  certificates representing ownership of the Registrable Securities being
  sold in such numbers and denominations as Holders shall reasonably request,
  meeting the requirements of the Principal Trading Market;
 
    (d) use its best efforts to cause the registration statement to remain
  current and effective for sixty (60) days following its effective date or
  such lesser period as the underwriters may agree; and
 
    (e) instruct the transfer agent(s) and the registrar(s) of Company's
  securities to release the stop transfer orders with respect to the
  Registrable Securities being sold.
 
    (f) Company will promptly prepare and file with the Commission such
  amendments and prospectus supplements, including post-effective amendments,
  to the Registration Statement as Company determines may be necessary or
  appropriate, and use its best efforts to have such post-effective
  amendments declared effective as promptly as practicable; cause the related
  prospectus to be supplemented by any prospectus supplement, and as so
  supplemented, to be filed with the Commission; and notify the Holders of
  any securities included in such Registration Statement and the underwriter
  thereof, if any, promptly when a prospectus, any prospectus supplement or
  post-effective amendment must be filed or has been filed and, with respect
  to any post-effective amendment, when the same has become effective, and
  make the same available to such Holders and any underwriter.
 
    (g) Company will furnish to each Holder and the underwriter thereof, if
  any, a signed counterpart, addressed to each Holder and underwriter, of (i)
  an opinion or opinions of counsel to Company and (ii) a comfort letter or
  comfort letters from Company's independent public accountants, each in
  customary form and covering such matters of the type customarily covered by
  opinions or comfort letters, as the case may be, as Holders or the
  underwriter may reasonably request.
 
 
                                    III-15
<PAGE>
 
    (h) Company will make generally available to its securityholders, as soon
  as reasonably practicable, an earning statement covering a period of 12
  months, beginning three months after the effective date of the Registration
  Statement, which earning statement shall satisfy the provisions of Section
  11(a) of the Securities Act.
 
    (i) Company will use its best efforts to cause all such Registrable
  Securities to be listed in the Principal Trading Market, and on each
  securities exchange on which similar securities issued by Company are then
  listed.
 
  7.5 Conditions to Obligations of Company Under Registration
Covenants. Company's obligations to register the Registrable Securities owned
by Holders under Article 7 are subject to the following conditions.
 
    (a) Company (upon the decision of a majority of the Unaffiliated
  Directors) shall be entitled to postpone for up to ninety (90) days the
  filing of any registration statement under Section 7.2, if at the time it
  receives the request for registration such Unaffiliated Directors
  determine, in their reasonable judgment, that such registration and
  offering would materially interfere with any financing, acquisition,
  corporate reorganization or other material transaction involving Company or
  any of its Affiliates. Company shall promptly give Holders written notice
  of such determination.
 
    (b) Company may require that the number of shares of Registrable
  Securities offered for sale by Holders pursuant to a request for
  registration under Section 7.3 be decreased or excluded entirely if, in the
  opinion of Company's Investment Banking Firm, such reduction is desirable
  to permit the orderly distribution and sale of the securities being
  offered. If Company shall require such a reduction, Holders shall have the
  right to withdraw from the offering.
 
    (c) If Holders request registration pursuant to Section 7.2, Company will
  enter into an underwriting agreement containing representations, warranties
  and agreements not materially different from those customarily included in
  underwriting agreements with an issuer for a secondary distribution;
  provided, however, that Company will not be obligated to indemnify the
  Investment Banking Firms on terms materially different from those set forth
  in Section 7.8.
 
    (d) Company may require, as a condition to fulfilling its obligations
  under the registration covenants in Sections 7.2 and 7.3, the
  indemnification agreements provided in Section 7.8(b) from Holders and the
  underwriters.
 
    (e) It shall be a condition precedent to the obligations of Company to
  take action pursuant to this Article 7 that each Holder whose Registrable
  Securities are being registered, and each underwriter designated by such
  Holder, will furnish to Company such information and materials as Company
  may reasonably request and as shall be required in connection with the
  action to be taken by Company. To the extent possible Holders shall provide
  Company with any information and materials required to obtain acceleration
  of the effective date of the registration statement.
 
    (f) If, in the reasonable opinion of counsel to Company it is necessary
  or appropriate for Company to comply with any applicable rule, regulation,
  or release promulgated by the Commission, each Holder whose Registrable
  Securities are being registered and any underwriter participating in such
  public offering shall execute and deliver to Company an appropriate
  agreement, in form satisfactory to counsel for Company, that such Holder or
  underwriter will comply with all prospectus delivery requirements of the
  Act and with all anti-stabilization, manipulation, and similar provisions
  of Section 10 of the Exchange Act and any rules issued thereunder by the
  Commission, and will furnish to Company information about sales made in
  such public offering.
 
                                    III-16
<PAGE>
 
    (g) Holders of Common stock included in the registration statement shall
  not (until further notice) effect sales thereof after receipt of written
  notice (which may include notice by telegraph) from Company to suspend
  sales, to permit Company to correct or update a registration statement or
  prospectus; provided, however, that the obligations of Company with respect
  to maintaining any registration statement current and effective shall be
  extended by a period of days equal to the period such suspension is in
  effect.
 
    (h) At the end of the period during which Company is obligated to keep
  any registration statement current and effective (and any extensions
  thereof required by the preceding paragraph), and upon receipt of notice
  from Company of its intention to remove from registration the securities
  covered by such registration statement that remain unsold, Holders of
  Registrable Securities included in the registration statement shall
  discontinue sales of such Registrable Securities pursuant to such
  registration statement, and each such Holder shall notify Company of the
  number of shares registered belonging to such Holder that remain unsold
  promptly following receipt of such notice from Company.
 
  7.6 Expenses.
 
    (a) In connection with any registration pursuant to Section 7.2, all
  Registration Expenses (as defined below) shall be borne fifty percent (50%)
  by Company and fifty percent (50%) by Holders of the Registrable Securities
  on the basis of the number of shares registered by them, and all Selling
  Expenses (as defined below) shall be borne by Holders of the Registrable
  Securities on the basis of the number of shares registered by them. As used
  in this Section 7.6, "Registration Expenses" shall mean all expenses
  incurred by Company in complying with this Article 7, including, without
  limitation, all federal and state registration, qualification and filing
  fees, printing expenses, fees and disbursements of counsel for Company,
  Blue Sky fees and expenses, and the expense of any special audits incident
  to or required by such registration. As used in this Section 7.6, "Selling
  Expenses" shall mean all underwriting discounts and selling commissions
  applicable to the sale of Registrable Securities pursuant to this Agreement
  and all fees and disbursements of counsel for any Holder.
 
    (b) In connection with any registration pursuant to Section 7.3, Company
  shall pay all Registration Expenses and Selling Expenses, except to the
  extent the aggregate of such expenses exceeds the amount which Company
  would have expended in conducting an offering of only the shares sold by
  it, and the participating Holders pro rata shall pay such excess based on
  the number of shares of Registrable Securities offered by each pursuant to
  such registration statement. Such Holders shall pay all Registration
  Expenses and Selling Expenses directly attributable to the inclusion in the
  offering of Registrable Securities being sold by the Holders, including
  without limitation fees and disbursements of their own counsel and
  accountants.
 
  7.7 Assignability of Registration Rights. The registration rights afforded
Purchaser in this Article 7 shall be assignable to a transferee of Registrable
Securities from Purchaser so long as (i) such transferee has acquired no fewer
than two million (2,000,000) shares of Registrable Securities (as adjusted
from time to time to reflect stock splits, stock dividends and similar changes
in the capitalization of Company) from Purchaser, (ii) such transferee has
agreed with Company in writing to comply with all applicable provisions of
this Article 7, and (iii) Purchaser has otherwise complied with all provisions
of this Agreement which affect its right to sell, transfer or otherwise
dispose of shares of Registrable Securities. For a transfer of registration
rights to be effective, Purchaser shall give Company written notice at the
time of such transfer stating the name and address of the transferee and
identifying the shares with respect to which the rights under this Article 7
are being assigned.
 
  7.8 Indemnification.
 
    (a) In the case of each registration effected by Company pursuant to
  Section 7.2 or 7.3, to the extent permitted by law, Company ("indemnifying
  party") agrees to indemnify and hold
 
                                    III-17
<PAGE>
 
  harmless each Holder, its officers and directors, and each underwriter
  within the meaning of Section 15 of the Act, against any and all losses,
  claims, damages, liabilities or actions to which they or any of them may
  become subject under the Act or any other statute or common law, including
  any amount paid in settlement of any litigation, commenced or threatened,
  if such settlement is effected with the written consent of Company, and to
  reimburse them for any legal or other expenses incurred by them in
  connection with investigating any claims and defending any actions, insofar
  as any such losses, claims, damages, liabilities or actions arise out of or
  are based upon (i) any untrue statement or alleged untrue statement of a
  material fact contained in the registration statement relating to the sale
  of such shares, or any post-effective amendment thereto, or the omission or
  alleged omission to state therein a material fact required to be stated
  therein or necessary to make the statements therein not misleading, (ii)
  any untrue statement or alleged untrue statement of a material fact
  contained in any preliminary prospectus, if used prior to the effective
  date of such registration statement, or contained in the final prospectus
  (as amended or supplemented if Company shall have filed with the Commission
  any amendment thereof or supplement thereto) if used within the period
  during which Company is required to keep the registration statement to
  which such prospectus relates current under Section 7.4(d) (including any
  extensions of such period as provided in Section 7.5(g)), or the omission
  or alleged omission to state therein (if so used) a material fact necessary
  to make the statements therein, in light of the circumstances under which
  they were made, not misleading; provided, however, that the indemnification
  agreement contained in this Section 7.8(a) shall not (x) apply to such
  losses, claims, damages, liabilities or actions arising out of, or based
  upon, any such untrue statement or alleged untrue statement, or any such
  omission or alleged omission, if such statement or omission was made in
  reliance upon and in conformity with information furnished to Company by
  such Holder or underwriter for use in connection with preparation of the
  registration statement, any preliminary prospectus or final prospectus
  contained in the registration statement, or any amendment or supplement
  thereto, or (y) inure to the benefit of any underwriter or any Person
  controlling such underwriter, if such underwriter failed to send or give a
  copy of the final prospectus to the Person asserting the claim at or prior
  to the written confirmation of the sale of such securities to such Person
  and if the untrue statement or omission concerned had been corrected in
  such final prospectus.
 
    (b) In the case of each registration effected by Company pursuant to
  Section 7.2 or 7.3 above, each Holder and each underwriter of the shares to
  be registered (each such party and such underwriters being referred to
  severally as an "indemnifying party") shall agree in the same manner and to
  the same extent as set forth in Section 7.8(a) to indemnify and hold
  harmless Company, each Person (if any) who controls Company within the
  meaning of Section 15 of the Act, the directors of Company and those
  officers of Company who shall have signed any such registration statement,
  with respect to any untrue statement or alleged untrue statement in, or
  omission or alleged omission from, such registration statement or any post-
  effective amendment thereto or any preliminary prospectus or final
  prospectus (as amended or supplemented, if amended or supplemented)
  contained in such registration statement, if such statement or omission was
  made in reliance upon and in conformity with information furnished to
  Company by such indemnifying party for use in connection with the
  preparation of such registration statement or any preliminary prospectus or
  final prospectus contained in such registration statement or any such
  amendment or supplement thereto.
 
    (c) Each indemnified party will, promptly after receipt of written notice
  of the commencement of an action against such indemnified party in respect
  of which indemnity may be sought under this Section 7.8, notify the
  indemnifying party in writing of the commencement thereof. In case any such
  action shall be brought against any indemnified party and it shall so
  notify an indemnifying party of the commencement thereof, the indemnifying
  party will be entitled to participate therein, with the approval of any
 
                                    III-18
<PAGE>
 
  indemnified parties, which approval shall not be unreasonably withheld, and
  to the extent it may wish, jointly with any other indemnifying party
  similarly notified, to assume the defense thereof with counsel satisfactory
  to such indemnified party, and after notice from the indemnifying party to
  such indemnified party of its election so to assume the defense thereof,
  the indemnifying party will not be liable to such indemnified party under
  this Section 7.8 for any legal or other expenses subsequently incurred by
  such indemnified party in connection with the defense thereof other than
  reasonable costs of investigation. Notwithstanding the foregoing, an
  indemnified party shall have the right to employ separate counsel
  (reasonably satisfactory to the indemnifying party) to participate in the
  defense thereof, but the fees and expenses of such counsel shall be the
  expense of such indemnified party unless the named parties to such action
  or proceedings include both the indemnifying party and the indemnified
  party and the indemnifying party or such indemnified party shall have been
  advised by counsel that there are one or more legal defenses available to
  it which are different from or additional to those available to the
  indemnifying party (in which case, if the indemnified party notifies the
  indemnifying party in writing that it elects to employ separate counsel at
  the reasonable expense of the indemnifying party, the indemnifying party
  shall not have the right to assume the defense of such action or proceeding
  on behalf of the indemnified party, as the case may be, it being
  understood, however, that the indemnifying party shall not, in connection
  with any such action or proceeding or separate or substantially similar or
  related action or proceeding in the same jurisdiction arising out of the
  same general allegations or circumstances, be liable for the reasonable
  fees and expenses of more than one separate counsel at any time for the
  indemnifying party and all indemnified parties, which counsel shall be
  designated in writing by the Holders of a majority of the Common Shares).
  If the indemnifying party withholds consent to a settlement or proposed
  settlement by the indemnified party, it shall acknowledge to the
  indemnified party its indemnification obligations hereunder. The indemnity
  agreements in this Section 7.8 shall be in addition to any liabilities
  which the indemnifying parties may have pursuant to law.
 
    (d) If the indemnification provided for in this Section 7.8 from an
  indemnifying party is unavailable to an indemnified party hereunder in
  respect to any losses, claims, damages, liabilities or expenses referred to
  herein, then the indemnifying party, in lieu of indemnifying such
  indemnified party, shall contribute to the amount paid or payable by such
  indemnified party as a result of such losses, claims, damages, liabilities
  or expenses in such proportion as is appropriate to reflect the relative
  fault of the indemnifying party and indemnified party in connection with
  the statements or omissions which result in such losses, claims, damages,
  liabilities or expenses, as well as any other relevant equitable
  considerations. The relative fault of such indemnifying party and
  indemnified party shall be determined by reference to, among other things,
  whether the untrue or alleged untrue statement of a material fact or the
  omission or alleged omission to state a material fact relates to
  information supplied by such indemnifying party or indemnified party and
  that party's relative intent, knowledge, access to information supplied by
  such indemnifying party or indemnified party and opportunity to correct or
  prevent such statement or omission. The amount paid or payable by a party
  as a result of the losses, claims, damages, liabilities and expenses
  referred to above shall be deemed to include any legal or other fees or
  expenses reasonably incurred by such party in connection with investigating
  or defending any action, suit, proceeding or claim.
 
                                  ARTICLE 8.
 
                                  TERMINATION
 
  8.1 Termination. This Agreement shall terminate upon the earliest to occur
of the following:
 
    (a) Purchaser's completion of a tender offer in accordance with Section
  2.10, provided, that Purchaser's offer has been accepted by shareholders
  owning not less than two-thirds ( 2/3) of the outstanding Common Stock, as
  provided in such Section; or
 
                                    III-19
<PAGE>
 
    (b) by mutual written agreement of Company and EMI; or
 
    (c) if the transactions contemplated under the Common Share Purchase
  Agreement shall not have been consummated, on August 1, 1995; or
 
    (d) if elected by EMI, exercisable upon delivery of written notice
  thereof to Company, upon the failure of Company to comply with its
  obligations under this Agreement and cure of such failure does not occur
  within thirty (30) days after EMI has given written notice of such failure
  to Company; or
 
    (e) if elected by Company, exercisable upon delivery of written notice
  thereof to EMI, upon the failure of Purchaser to comply with its
  obligations under this Agreement and cure of such failure does not occur
  within thirty (30) days after Company gives written notice of such failure
  to EMI.
 
  8.2 Extended Cure Period. Notwithstanding Sections 8.1(d) and 8.1(e), the
parties agree that if the nature of the failure requires that more than thirty
(30) days are necessary to cure, this Agreement shall not terminate if the
failing party commences a cure within the thirty (30) day period and
thereafter continuously and diligently pursues all steps necessary to cure the
failure up to and including completion of the cure; provided, however, that
such extended cure period shall terminate sixty (60) days after the expiration

[LETTERHEAD OF GOLDMAN, SACHS & CO. APPEARS HERE] 

                                                                       EXHIBIT V


- --------------------------------------------------------------------------------

May 24, 1995


Board of Directors
VWR Corporation
1310 Goshen Parkway
West Chester, PA 19380


Gentlemen:

You have requested our opinion as to the fairness to VWR Corporation (the 
"Company") of the cash consideration to be paid for the industrial distribution 
business of the Industrial and Life Sciences Division (the "Distribution 
Business") of Baxter International, Inc. ("Baxter") pursuant to the Asset 
Purchase Agreement (the "Agreement") dated as of May 24, 1995, by and among 
Baxter and the Company. Pursuant to the Agreement, the Company will pay Baxter 
$400,000,000 in cash (the "Consideration") for the Distribution Business, 
subject to adjustments under certain circumstances as more fully set forth in 
the Agreement.
 
Goldman, Sachs & Co., as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with 
mergers and acquisitions, negotiated underwritings, competitive biddings, 
secondary distributions of listed and unlisted securities, private placements 
and valuations for estate, corporate and other purposes. We are familiar with 
the Company having acted as its financial advisor in connection with, and having
participated in certain of the negotiations leading to, the Agreement and are 
currently discussing with the Company our possible participation in the Senior 
Debt Facility used to finance a portion of the transactions pursuant to the 
Agreement. We have also provided, and may provide in the future, certain 
investment banking services to Baxter. Recent investment banking services 
provided to Baxter include serving as a managing underwriter of public offerings
of Baxter's debt securities and acting as agent for Baxter's commercial paper. 
In the course of trading activity we have accumulated a net short position of 
21,754 Baxter shares.

In connection with this opinion, we have reviewed, among other things, the 
Agreement, annual reports, 10-K's and interim 10-Q's of the Company and Baxter 
for the five years ended December 31, 1994. For the Distribution Business, we 
have reviewed certain internal financial analyses and unaudited financial 
results for the three years ended December 31, 1994, projected financial 
forecasts for 1995 prepared by Baxter and projected financial forecasts for 
1995-1999 prepared by the Company as of April 20, 1995. We note that audited 
financial information for the Distribution Business has not been prepared and, 
accordingly, has not been reviewed by us. We have also held discussions with 
members of the senior managements of Baxter and the Distribution Business 
regarding its past and current business operations, financial condition and we 
have also held discussions with members of the senior management of the Company,
Baxter and the Distribution Business regarding future prospects of the 
Distribution Business. In addition, we have compared

certain financial information for the Distribution Business with similar 
information for certain other companies the securities of which are publicly 
traded, reviewed the financial terms of certain recent business combinations in 
the distribution industry specifically and in other industries generally and 
performed such other studies and analyses as we considered appropriate. We are 
expressing no opinion with respect to any transaction undertaken by the Company 
to finance the transactions pursuant to the Agreement.

We have relied without independent verification upon the accuracy and 
completeness of all of the financial and other information reviewed by us for 
purposes of this opinion. In that regard, we have assumed with your consent, 
that the financial forecasts prepared by Baxter and the Company, including, 
without limitation, projected cost savings and operating synergies resulting 
from the acquisition of the Distribution Business by the Company and other 
acquisition related adjustments have been reasonably prepared on a basis 
reflecting the best currently available judgments and estimates of Baxter and 
the Company and that such forecasts will be realized in the amounts and at the 
times contemplated thereby. In addition, we have not made an independent 
evaluation or appraisal of the assets and liabilities of the Distribution 
Business. We have not been furnished with any such evaluation or appraisal. We 
have also assumed that the Company will receive all necessary regulatory 
approvals to complete the transactions contemplated by the Agreement without 
undue delay.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof, the
Consideration to be paid by the Company for the Distribution Business pursuant
to the Agreement is fair to the Company.

Very truly yours,

/s/ Goldman, Sachs & Co.

trade payables arising from the purchase of products and/or inventory used in
or sold by the Industrial Distribution Business. The assumption of the Assumed
Liabilities by Buyer hereunder shall not enlarge any rights of third parties
under contracts or arrangements with Buyer or Seller and nothing herein shall
prevent any party from contesting in good faith with any third party any of
said Assumed Liabilities.
 
1.4 Purchase Price and Payment
 
  (a) Amount Payable. In consideration of the sale by Seller to Buyer of the
Subject Assets and the satisfaction of all of the conditions contained herein,
Buyer shall at the Closing deliver to Seller $400,000,000 by wire transfer of
immediately available funds (such amount being herein referred to as the
"Purchase Price"). The Purchase Price shall be subject to adjustment as
provided for herein.
 
  (b) Closing Statement of Assets and Liabilities.
 
    (i) as soon as practicable, but in any event within 60 days after the
  Closing, Seller will cause to be prepared and delivered to Buyer a
  statement of assets and liabilities of the Industrial Distribution Business
  (the "Closing Statement of Assets and Liabilities") reflecting the Subject
  Assets and the Assumed Liabilities as of the Closing Date.
 
    (ii) The Closing Statement of Assets and Liabilities shall be prepared
  from the books and records of Seller relating to the Industrial
  Distribution Business in a manner consistent with that of the statement of
  assets and liabilities of the Industrial Distribution Business as of March
  31, 1995 attached as Schedule 1.4(b)(ii) (the "Pre-Closing Statement of
  Assets and Liabilities"). Buyer shall cooperate with Seller in the
  preparation of the Closing Statement of Assets and Liabilities to the
  extent reasonably requested by Seller. The items reflected on such Closing
  Statement of Assets and Liabilities shall be calculated in accordance with
  generally accepted accounting principles ("GAAP"), including an allowance
  for uncollectible Industrial Accounts Receivable, as applied in a manner
  consistent with the Pre-Closing Statement of Assets and Liabilities, except
  that the calculation of Industrial Accounts Receivable shall exclude any
  reserves for price adjustments, billing errors and returns. Buyer and
  Seller acknowledge that no value shall be given on such statement to any
  goodwill. Buyer and Seller shall have full access to the accounting records
  from which the Closing Statement of Assets and Liabilities will be derived
  and may, at the option of either of them and at their own expense, have
  representatives present to observe any part of the preparation of the
  Closing Statement of Assets and Liabilities or any other matter relating
  thereto.
 
    (iii) Subject to subparagraph 1.4(b)(iv), the Closing Statement of Assets
  and Liabilities delivered by Seller to Buyer shall be final, binding and
  conclusive on the parties hereto for all purposes of this Agreement and
  shall provide the basis for determining (1) the liabilities and obligations
  of Seller to be assumed pursuant to paragraph 1.2 and (2) the adjustments
  (if any) specified in subparagraph 1.4(c).
 
                                     VI-5
<PAGE>
 
    (iv) (A) Buyer, at its own expense, may conduct an audit, review or other
  report of the Closing Statement of Assets and Liabilities, including
  causing any nationally recognized firm of independent public accountants
  designated by Buyer and reasonably acceptable to Seller which, for purposes
  hereof, shall include Ernst & Young L.L.P. ("Buyer's Accountants") to
  perform such audit, review or other report. Buyer may dispute the Closing
  Statement of Assets and Liabilities, but only on the basis that the items
  on the Closing Statement of Assets and Liabilities were not calculated in
  accordance with GAAP as applied in a manner consistent with the Pre-Closing
  Statement of Assets and Liabilities. Any such dispute shall be initiated by
  written notice delivered to Seller within 30 days of Buyer's receipt of the
  initial Closing Statement of Assets and Liabilities specifying each
  disputed item, the amount thereof and the basis on which such dispute is
  made.
 
         (B) In the event of such a dispute, Seller and Buyer shall attempt to
    reconcile their differences and any written resolution by them as to
    any disputed amounts shall be final, binding and conclusive on the
    parties, and Seller shall revise the Closing Statement of Assets and
    Liabilities in accordance with such written resolution.
 
         (C) If Seller and Buyer are unable to reach a written resolution of
    all disputed items within 20 days after Buyer's written notice of
    dispute, Seller and Buyer shall submit the items remaining in dispute
    for resolution to a firm of independent public accountants having
    national standing in the United States which is not then retained by
    Seller, Buyer or their respective Affiliates, as mutually selected by
    Buyer and Seller (the "Neutral Accounting Firm"). In the event that
    Seller and Buyer are unable to agree on the Neutral Accounting Firm,
    then a nationally recognized "Big Six" accounting firm will be selected
    by lot after eliminating one such firm selected by Seller and one such
    firm selected by Buyer. The Neutral Accounting Firm shall, within 30
    days after submission to it of the disputed items, determine and report
    in writing to the parties upon such remaining disputed items in
    accordance with the provisions hereof; and such report shall be final,
    binding and conclusive on the parties hereto. The fees and
    disbursements of the Neutral Accounting Firm shall be allocated between
    Seller and Buyer in the same proportion that the aggregate amount of
    such remaining disputed items so submitted to the Neutral Accounting
    Firm that is unsuccessfully disputed by each (as finally determined by
    the Neutral Accounting Firm) bears to the total amount of such
    remaining disputed items so submitted. The Neutral Accounting Firm
    shall make such determination in its sole discretion, subject to the
    terms and conditions of this Agreement; provided, however, that the
    amount determined by the Neutral Accounting Firm in respect of any such
    remaining disputed item shall not exceed the highest amount claimed by
    either of the parties disputing such item, or be less than the lowest
    amount claimed by either of the parties disputing such item. The
    Closing Statement of Assets and Liabilities as finally determined in
    accordance with subparagraph (b)(iii) or (iv) shall constitute the
    Closing Statement of Assets and Liabilities for all purposes of this
    Agreement.
 
  (c) Purchase Price Adjustment. In the event that the final determination of
the Closing Statement of Assets and Liabilities indicates that the amount
obtained (the "Closing Date Net Asset Amount") by subtracting (i) the Assumed
Liabilities reflected on the Closing Statement of Assets and Liabilities from
(ii) the Subject Assets reflected on the Closing Statement of Assets and
Liabilities is less than $45,000,000, the amount of the difference shall be an
adjustment in favor of Buyer to be refunded to Buyer, as a reduction of the
Purchase Price, within 10 days of the final determination of such adjustment.
In the event that the final determination of the Closing Statement of Assets
and Liabilities indicates that the Closing Date Net Asset Amount is greater
than $45,000,000 the aggregate amount of the difference shall be an adjustment
in favor of Seller to be paid to Seller, as an increase of the Purchase Price,
within 10 days of the final determination of such adjustment.

Philadelphia, Pennsylvania at 10:00 A.M., local time, on such date and time as
may be fixed by mutual agreement of Buyer and Seller as soon as practicable
following satisfaction of the conditions contained in Section 7 (such date and

1.6 Transfer of Subject Assets
 
  At the Closing, Seller shall deliver or cause to be delivered to Buyer a
bill of sale and assignment, in substantially the form of Exhibit 1.6(a),
together with such additional documents and instruments as may be reasonably
requested by Buyer, transferring to Buyer all of Seller's right, title and
interest in, to and under the Subject Assets. At the Closing, Buyer shall
deliver to Seller an assumption agreement, in substantially the form of
Exhibit 1.6(b), together with such additional documents and instruments as may
be reasonably requested by Seller, evidencing Buyer's agreement to pay,
perform and discharge the Assumed Liabilities.
 
1.7 Delivery of Records and Contracts
 
  At the Closing, or at such later time as Buyer may direct, subject to
paragraph 1.9, Seller shall deliver or cause to be delivered to Buyer all of
the Contracts; Seller shall also deliver to Buyer at the Closing, or at such
later time as Buyer may direct, all of Seller's business records, books and
other data relating exclusively to the Industrial Distribution Business and
forming part of the Subject Assets, and Seller shall take all requisite steps
to put Buyer in actual possession and operating control of the Subject Assets
and the Industrial Distribution Business. After the Closing, (i) Buyer shall
afford to Seller, and its Affiliates and their accountants and attorneys, for
all reasonable business purposes after the Closing, reasonable access to the
books and records of Seller delivered to Buyer under this Section and shall
permit Seller, at Seller's expense, to make extracts and copies therefrom and
(ii) Seller shall afford to Buyer, and its Affiliates and their accountants
and attorneys, for all reasonable business purposes related to the operation
of the Industrial Distribution Business after the Closing Date, reasonable
access to the books and records of Seller relating to the Industrial
Distribution Business which are retained by Seller pursuant to paragraph
1.1(b) and shall permit Buyer, at Buyer's expense, to make copies and extracts
therefrom. The parties each covenant to take such care in keeping and storing
all such books and records retained by such party as would a prudent owner
thereof. Such books and records shall be retained for a period of six years
after the Closing Date or, in the case of books and records required to
support tax returns and tax audits, ten years after the Closing Date, and
thereafter, as the case may be, shall only be destroyed after first giving
notice to the other party of such intention to destroy and providing a
reasonable opportunity, at such other party's expense, to segregate and remove
such books and records, if any, as such other party may select.
 
1.8 Non-Assignable Contracts
 
  (a) Non-Assignability. Nothing in this Agreement will constitute a transfer
or an attempted transfer of any Contract which is not capable of being
transferred without the consent, approval, waiver or novation of a third
person or entity, or with respect to which such transfer or attempted transfer
would constitute a breach thereof or a violation of any Law, other than those
for which such consents, approvals, waivers or novations have been obtained by
Seller prior to the Closing Date (such nontransferable Contracts and permits
being collectively referred to herein as "Unassigned Contracts").
 
                                     VI-7
<PAGE>
 
  (b) Consents, Approvals, etc. Notwithstanding anything contained in this
Agreement to the contrary, Seller shall not be obligated to transfer to Buyer
any of its rights and obligations in and to any Unassigned Contract without
first having obtained all consents, approvals, waivers and novations necessary
for such transfer under the terms of such Unassigned Contract or applicable
law, at which time such Unassigned Contract will, without further action, be
deemed to be transferred to Buyer.
 
  (c) If Consents, Approvals, etc. Are Not Obtained. Prior to the Closing
Date, Seller shall use its commercially reasonable efforts to obtain the
consents, approvals, waivers and novations referred to in subparagraph 1.8(a),
provided that the only consents required prior to Closing are the consents, if
any, referred to in subparagraph 7.1(f). To the extent that the consents,
approvals, waivers and novations referred to in subparagraph 1.8(a) are not
obtained by Seller, Seller will, as to each Unassigned Contract, use its
commercially reasonable efforts after the Closing Date to provide to Buyer the
full benefits of such Unassigned Contracts, cooperate in any lawful
arrangement designed to provide such benefits to Buyer without incurring any
obligation to any third party, and enforce, at the request of Buyer, at the
cost of and for the account of Buyer, any rights of Seller arising from any
such Unassigned Contract (including, without limitation, the right to elect to
terminate in accordance with the terms thereof upon the request of Buyer).
 
1.9 Further Assurances
 
  Seller from time to time after the Closing at the request of Buyer and
without further consideration shall execute and deliver such further
instruments of transfer and assignment and take such other action as Buyer may
reasonably require to more effectively transfer and assign to, and vest in,
Buyer good title, subject to Permitted Encumbrances (as defined in paragraph
13.1 hereof), to each of the Subject Assets.
 
1.10 Allocation of Purchase Price
 
  The Purchase Price shall be allocated among the Subject Assets as set forth
on Schedule 1.10 hereto (the "Allocation"). The Allocation shall be adjusted
downward or upward, as the case may be, as appropriate to reflect any
adjustments in the Purchase Price pursuant to paragraph 1.4(c). Seller and
Buyer agree that they shall file Internal Revenue Service Form 8594, and all
income tax returns and other documents that they may be required to file on a
basis that is consistent with the Allocation. Buyer and Seller each agree to
provide the other promptly with any other information required to complete
Form 8594. Buyer and Seller shall give prompt notice to each other of the
commencement of any tax audit or the assertion of any proposed deficiency or
adjustment by any taxing authority which challenges the Allocation.

  Buyer shall be liable for and shall pay at the time of Closing all federal,
foreign and state sales taxes and all other sales taxes, duties, documentary
stamps, transfer taxes, registration fees and charges or other like charges

the Subject Assets by Seller to Buyer hereunder.

notifications and other information required to be filed under the Hart-Scott-

file as promptly as practicable such additional information as may be
requested. Each of Buyer and Seller warrants that all such filings by it will

assets and property (including, in the case of Seller, the Industrial
Distribution Business) as may be required of each of them, to file any
additional information requested by such agencies under the Improvements Act
and any such rules and regulations or as may be reasonably requested to
facilitate completion of the review process and expedite expiration of the
applicable waiting period.
 
6.2 Non-Solicitation
 
  (a) Neither Buyer nor any Affiliate of Buyer shall, for a period of two
years after the Closing Date or the termination of this Agreement, as the case
may be, without the prior written approval of Seller, directly or indirectly
solicit, induce or attempt to persuade any person who is (i) in the case of a
termination of this Agreement, an employee of Seller or any of its Affiliates
on the date hereof or any time thereafter that precedes such termination or
(ii) in the case the Closing is consummated,
 
                                     VI-20
<PAGE>
 
an employee of Seller or any of its Affiliates on the date hereof or any time
thereafter that precedes the Closing (and who is not otherwise a Business
Employee), to terminate his or her employment with Seller or its Affiliates.
 
  (b) Neither Seller nor any Affiliate of Seller shall, for a period of two
years after the Closing Date or the termination of this Agreement, as the case
may be, without the prior written approval of Buyer, directly or indirectly
solicit, induce or attempt to persuade any person who is an employee of Buyer
or any of its Affiliates on the date hereof or any time hereafter that
precedes such termination or the Closing, to terminate his or her employment
with Buyer or its Affiliates. Notwithstanding the foregoing, any Business
Employee (a) who declines Buyer's offer of employment or (b) whose employment
is terminated by Buyer shall be eligible for employment by Seller.
 
  (c) Notwithstanding anything contained herein to the contrary, a general
advertising or solicitation by any party for employment positions and contacts
initiated by an employee in response to an advertisement or by an employee
otherwise seeking to change his or her employment shall not be deemed
prohibited by the provision of this paragraph 6.2.

other hand, to pursue all other legal and equitable rights available for a
violation of this paragraph 6.2 by the other or its Affiliates, Seller and
Buyer each acknowledge that other remedies cannot fully compensate Seller or
Buyer, as the case may be, for such a violation and that Seller or Buyer, as
the case may be, shall be entitled to injunctive relief to prevent a violation
or continuing violation hereof. It is the intent and understanding of each
party hereto that if, in any action before any court or agency legally
empowered to enforce this paragraph 6.2, any term, restriction, covenant or
promise in this paragraph 6.2 is found to be unreasonable and for that reason
unenforceable, then such term, restriction, covenant or promise shall be
deemed modified to the extent necessary to make it enforceable by such court
or agency.
 
6.3 Restricted Marks
 
  Notwithstanding anything contained herein to the contrary, no interest in or
right to use any of the Restricted Marks is being transferred to Buyer
pursuant to the transactions contemplated hereby. Except as provided in the
Distribution Agreement and the Services Agreement, Buyer shall remove or
obliterate all references to the Restricted Marks, if any, from any signs,
purchase orders, invoices, sales orders, labels, letterheads, shipping
documents and other materials included in the Subject Assets purchased by
Buyer hereunder and Buyer shall not put into use after the Closing Date any
such materials not in existence on the Closing Date that bear any reference to
the Restricted Marks. In addition, in designing its own packaging, labeling,
logos and trademarks for use in connection with products manufactured or
distributed by Buyer after the Closing, Buyer shall not use any trademarks,
service marks, designs, logos or trade dress (including, without limitation,
the "Baxter Blue" color as defined in the Pantone Matching System 747XR as
shades numbers 285, 286, 287, 288, 289 and 290) that are confusingly similar
to the Restricted Marks. Notwithstanding the foregoing, Buyer shall be
entitled for a transition period not exceeding the three-month anniversary of
the Closing Date to use any such materials bearing a reference to the
Restricted Marks if the removal of any such reference prior to the expiration
of such transition period would be impractical. Buyer agrees that neither
Seller nor any Affiliate thereof shall have any responsibility for claims by
third parties arising out of, or relating to, the use by Buyer or any
successor thereof of any materials bearing reference to the Restricted Marks
after the Closing Date.

                                   SECTION 8
 
                  CERTAIN EMPLOYEE AND EMPLOYEE PLAN MATTERS
 
8.1 Offers of Employment
 
  Prior to the Closing, Buyer shall offer employment to all Business
Employees, which as of April 26, 1995 is 569 Business Employees. Any Business
Employee who is on a leave of absence due to disability (including but not
limited to maternity leave) which terminates within the one-year period
beginning on the Closing Date shall receive an offer of employment from Buyer
on the date such leave of absence terminates. The terms of employment offered
to such Business Employees shall be based on Buyer's existing employment
practices and policies, provided that it shall be a term of such offer that
each such Business Employee be entitled to receive (a) cash compensation
(including bonuses) based on a pay scale which is no less generous than
Seller's pay scale, (b) employee benefits which are no less generous than
those provided to similarly situated employees of Buyer, and (c) severance
benefits, or payments in lieu of notice in accordance with Seller's severance
pay policies in effect immediately prior to the Closing as set forth on the
Disclosure Statement (the "Severance Pay Policies") in the event that his or
her employment is terminated by Buyer within 6 months of the Closing. Buyer
shall assume any and all obligations for vacation pay earned by Business
Employees who accept employment with Buyer prior to the Closing Date. Pursuant
to the terms of the Baxter International Inc. and Subsidiaries Incentive
Investment Plan (the "Seller's Savings Plan") and within the time limits
prescribed by applicable law, Seller shall transmit to the Seller's Savings
Plan all contributions withheld from the
 
                                     VI-25
<PAGE>
 
compensation earned by Business Employees prior to the Closing Date pursuant
to the salary reduction elections of such employees ("401(k) contributions")
and all matching contributions attributable to such 401(k) contributions.
 
  Seller shall assist Buyer in securing acceptances from Business Employees to
whom Buyer offers employment. In the event that less than all of the Business
Employees accept offers of employment from Buyer, Buyer shall pay to Seller,
at the time of Closing, one-half of the aggregate amount payable by Seller
pursuant to the Severance Pay Policies to those Business Employees who, as of
the Closing Date, have rejected such offers, it being acknowledged and
understood that, through this mechanism, Buyer shall hire and/or partially
fund the cost to terminate all of the Business Employees. Seller shall use all
such funds received from Buyer to partially fund the cost to terminate
Business Employees pursuant to the Severance Pay Policies, provided that
Seller may, in its discretion, terminate Business Employees who are offered
employment by Buyer and do not accept such offer of employment. With respect
to any Business Employee who is an outside sales representative and who
accepts Buyer's offer of employment, but who is terminated within the 60-day
period following the Closing Date, Seller shall pay to Buyer within ninety
days after the Closing Date one-half of the aggregate amount payable as
severance benefits to such terminated employee. Notwithstanding anything
herein to the contrary, the maximum amount which Seller shall be obligated to
pay for severance benefits with respect to Business Employees who are outside
sales representatives who are terminated by Buyer following the Closing Date
is $750,000. Buyer shall have no severance pay obligations with respect to any
Business Employees who decline Buyer's offer of employment and are continued
as employees of Seller.
 
  The provisions of this paragraph 8.1 shall not apply to the President of the
Industrial Distribution Business.
 
8.2 Buyer's Assumption of Employee Liability and Indemnity
 
  Subject to paragraph 8.1, Buyer shall assume and be solely responsible for
the past service liability of Seller under the Severance Pay Policies for 6
months following the Closing and as otherwise imposed by law in respect of all
Business Employees who accept offers of employment from Buyer.
 
8.3 Benefit Plans and Pension Plans
 
  Buyer shall not assume any obligations arising under any "employee benefit
plan" (as such term is defined in Section 3(3) of ERISA) which Seller
maintains relating to any Business Employee (collectively the "Plans"). The
participation of the Business Employees in the Plans shall be terminated as of
the Closing Date, in each case except to the extent that any rights under the
Plans shall have vested, or may vest upon fulfillment of certain conditions,
in accordance with the terms contained therein; provided, however, that
Business Employees who accept employment with Buyer shall be 100% vested in
their account balances under the Seller's Savings Plan and in their accrued
benefits under the Baxter International Inc. Pension Plan.
 
8.4 Buyer's Plans
 
  Buyer shall provide for the participation, commencing on the Closing Date by
such of the Business Employees who accept offers of employment from Buyer and
who participated in the Plans prior to the Closing Date, in Buyer's employee
benefits plans, provided that for purposes of eligibility to participate and
vesting under Buyer's plans (but not for purposes of benefit accruals), Buyer
shall take any and all action necessary (including amendment of Buyer's plans)
to recognize each Business Employee's service with Seller. Buyer shall
recognize each Business Employee's
 
                                     VI-26
<PAGE>
 
years of service with Seller for all purposes under the Buyer's sick and
disability pay plan. No Business Employee's participation in any of Buyer's
employee benefit plans shall be limited or restricted due to a preexisting
condition limitation in such plan.
 
8.5 Continuation Coverage
 
  Buyer acknowledges that Seller is not obligated to offer "continuation
coverage" as provided by Part 6 of Title I of the Employee Retirement Income
Security Act of 1974, as amended and Section 4980B of the Internal Revenue
Code ("COBRA") under Seller's group health plans with respect to the Business
Employees who accept Buyer's offer of employment because Buyer shall be
providing as of the Closing Date group health plans which provide coverage
which is comparable to the coverage such Business Employees received
immediately prior to the Closing Date under the Seller's group health plans.
Seller shall retain liability for employees (and their qualified
beneficiaries) receiving continuation coverage as of the Closing Date under
Seller's group health plans. With respect to group health plans established by
Buyer or its Affiliates on or after the Closing Date and for the benefit of
Business Employees who accept employment with Buyer, or its Affiliates shall
comply with all COBRA obligations applicable to those plans.
 
8.6 WARN
 
  Buyer shall comply with all notice and other requirements under the Workers
Adjustment and Retraining Notification Act ("WARN") and any similar state,
local, or foreign country statute with respect to all Business Employees who
accept employment with Buyer and all other employees of Buyer. Seller shall
comply with all notice and any other requirements under WARN and any similar
state, local, or foreign country statute with respect to all Business
Employees who either are not offered employment with Buyer or who decline
offers of employment with Buyer as well as other employees of Seller.
 
                                   SECTION 9
 
                 RIGHTS AND OBLIGATIONS SUBSEQUENT TO CLOSING
 
9.1 Survival
 
  Except as otherwise provided in paragraph 10.2 with respect to Seller and

  Subsequent to the Closing, Buyer shall have the right and authority to
collect all Industrial Accounts Receivable and other items transferred and
assigned to it by Seller hereunder and to endorse with the name of Seller any
checks received on account of such receivables or other items, and Seller
agrees that, except as contemplated by subparagraph 1.1(b), it will promptly
transfer or deliver to Buyer from time to time, any cash or other property
that Seller may receive with respect to any claims, contracts, licenses,
leases, commitments, sales orders, purchase orders, receivables of any
character or any other items included in the Subject Assets.
 
9.3 Payment or Satisfaction of Excluded Liabilities
 
  Seller shall pay or satisfy all of the Excluded Liabilities in the ordinary
course of business as they become due, including but not limited to any
obligations owed to suppliers of the Industrial Distribution Business which
are included in the Excluded Liabilities.
 
                                     VI-27

9.4 Certain Additional Agreements
 
  (a) Buyer agrees to perform its pro rata portion of all distribution related
obligations under agreements, contracts, commitments and other written
understandings of Seller with suppliers or vendors relating to the Industrial
Distribution Business that are not transferred to Buyer as contemplated
hereby. Buyer's pro rata portion of such distribution related obligations
shall include all such obligations that are directly allocable to the
Industrial Distribution Business and the portion of such obligations that
relate to the Industrial Distribution Business and other portions of Seller's
business comparable to the portion of products purchased under such agreement
and sold to Industrial Customers during calendar year 1994.
 
  (b) Notwithstanding anything to the contrary contained herein, effective as
of the Closing Date, Buyer shall, as a subdistributor of Seller, assume and
agree to perform all contractual obligations of Seller pursuant to the terms
and conditions of the Exclusive Distribution Agreement dated as of December
19, 1994 between Dade International Inc. and Seller, including without
limitation the obligation of Seller to distribute in the United States

obligations relate to the distribution of products by Seller prior to the
Closing Date.

and in respect of any and all claims, demands, suits, damages, liabilities,
losses, fines, penalties, costs and expenses (including, without limitation,

  warranty of Seller contained in this Agreement, the Disclosure Statement or
  in any certificate, Schedule or Exhibit delivered by Seller hereunder, or
  by reason of any claim, action or proceeding asserted or instituted by a
  third party to the extent arising specifically out of any matter or thing
  specifically constituting a breach by Seller of, or inaccuracy in, any such
  representation or warranty of Seller;
 
    (b) any breach or nonfulfillment by Seller of any agreement or covenant
  of Seller contained in this Agreement, or by reason of any claim, action or

<PAGE>

    (d) unless a claim for indemnification is made prior to the date which is
  two years after the Closing Date;

inaccuracy are less than $20,000 in the aggregate.

of Buyer in respect of all such Losses shall be $300,000,000.
 
10.5 Notice: Defense of Claims
 
  (a) If any indemnified party shall receive notice of the assertion by a
person who is not a party to this Agreement of any claim or of the
commencement by any such person of any action or proceeding (a "Third Party
Claim") with respect to which an indemnifying party may be obligated to
provide indemnification pursuant to this Agreement, such indemnified party
shall give the indemnifying party written notice thereof promptly after
becoming aware of such Third Party Claim; provided, that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations hereunder, except to the extent that the
indemnifying party is actually prejudiced by such failure to give notice. Such
notice shall describe the Third Party Claim in reasonable detail, and shall
indicate the amount (estimated if necessary) of the indemnifiable Loss that
has been or may be sustained by such indemnified party.
 
  (b) The indemnifying party may elect to defend or to seek to settle or
compromise, at the indemnifying party's own expense and by the indemnifying
party's own counsel, any Third Party Claim. Within 30 days of the receipt of
notice from an indemnified party in accordance with subparagraph (a) above (or
sooner, if the nature of such a Third Party Claim so requires), the
indemnifying party shall notify the related indemnified party if the
indemnifying party elects not to defend or not to seek to settle or compromise
such Third Party Claim (which elections may be made only in the event of a
good faith assertion by the indemnifying party that a claim was
inappropriately tendered hereunder, as the case may be). Unless the
indemnifying party elects not to assume the defense or not to seek to settle
or compromise a Third Party Claim, the indemnifying party shall not be liable
to such indemnified party hereunder for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof; provided, that such indemnified party shall have the right to employ
one counsel to represent such indemnified party if, in such indemnified
party's reasonable judgment, a conflict of interest between such indemnified
party and the indemnifying party exists in respect of such claim, and in that
event the reasonable fees and disbursements of such separate counsel shall be
paid by the indemnifying party. If the indemnifying party elects not to defend
or to seek to compromise or settle a Third Party Claim, or fails to notify an
indemnified party of its election as provided herein, such indemnified party
may defend or seek to compromise or settle such Third Party Claim.
Notwithstanding the foregoing, neither the indemnifying party nor any
indemnified party may settle or compromise any claim over the objection of the
other; provided, however, that consent to settlement or compromise shall not
be unreasonably withheld. The indemnifying party
 
                                     VI-30
<PAGE>
 
shall not consent to entry of any judgment or enter into any settlement which
does not include as an unconditional term thereof the giving by the claimant
or plaintiff to such indemnified party of a release from all liability in
respect of such claim or litigation.
 
  (c) If the indemnifying party chooses to defend or to seek to compromise or
settle any Third Party Claim, the related indemnified party shall make
available to the indemnifying party any personnel or any books, records or
other documents within its control or which it otherwise has the ability to
make available that are necessary or appropriate for such defense, settlement
or compromise and shall otherwise cooperate in the defense, settlement or
compromise of such Third Party Claims.
 
  (d) Notwithstanding anything else herein, if any offer of settlement or
compromise is received by the indemnifying party with respect to a Third Party
Claim and the indemnifying party notifies the related indemnified party in
writing of the indemnifying party's willingness to settle or compromise such
Third Party Claim on the basis set forth in such notice and such indemnified
party declines to accept such settlement or compromise, such indemnified party
may continue to contest such Third Party Claim free of any participation by
the indemnifying party, at such indemnified party's sole expense. In such
event, the obligation of the indemnifying party to defend or to seek to settle
or compromise such Third Party Claim shall cease and the obligation of the
indemnifying party to such indemnified party with respect to such Third Party
Claim shall be limited to the lesser of (i) the amount of the offer of
settlement or compromise which such indemnified party declined to accept plus
the costs and expenses of such indemnified party prior to the date the
indemnifying party notifies such indemnified party of the offer to settle or
compromise and (ii) the actual out-of-pocket amount such indemnified party is
obligated to pay as a result of such indemnifying party's continuing to
contest such Third Party Claim. The indemnifying party shall be entitled to
recover (by set-off or otherwise) from any indemnified party any additional
expenses incurred by the indemnifying party as a result of such indemnified
party's decision to continue to contest such Third Party Claim.
 
  (e) Any claim on account of any Loss which does not result from a Third
Party Claim shall be asserted by written notice by the indemnified party to
the indemnifying party. The indemnifying party shall have a period of 60 days
after the receipt of such notice within which to respond thereto. If the
indemnifying party does not respond within such 60-day period, the
indemnifying party shall be deemed to have forfeited its right to contest the
claimed payment and shall have no further right to contest the validity of
such a claim. If the indemnifying party does not respond within such 60-day
period or rejects such a claim in whole or in part, such indemnified party
shall be free to pursue such remedies as may be available to such party under
applicable law.
 
  (f) If the amount of any indemnifiable Loss shall, at any time subsequent to
payment pursuant to this Agreement, be reduced by recovery, settlement or
otherwise, the amount of such reduction, less any expenses incurred in
connection therewith, shall promptly be repaid by the indemnified party to the
indemnifying party.
 
  (g) In the event of payment by the indemnifying party to any indemnified
party in connection with any Third Party Claim, the indemnifying party shall
be subrogated to and shall stand in the place of such indemnified party as to
any events or circumstances in respect of which such indemnified party may
have any right or claim relating to any Third Party Claim against any claimant
or plaintiff asserting such Third Party Claim. Such indemnified party shall
cooperate with the indemnifying party in a reasonable manner, and at the cost
and expense of the indemnifying party, in prosecuting any subrogated right or
claim.

10.6 Exclusive Remedy
 
  To the extent permitted by Law and except as set forth in paragraphs 11.2(b)
and (c), respectively, the respective remedies of Buyer and Seller contained
in this Section 10 shall be exclusive.
 
                                  SECTION 11
 
                    EXPIRATION OR TERMINATION OF AGREEMENT
 
11.1 Expiration or Termination
 
  If for any reason whatsoever Closing shall not have occurred on or before
October 31, 1995, and neither Buyer nor Seller shall have terminated the
Agreement as provided in clause (a) or (b) below, this Agreement shall
nevertheless expire at the close of business on October 31, 1995 without the
need for any further action by any party hereto. At any time prior to the
Closing, this Agreement may be terminated as follows:
 
    (a) by mutual written consent of Buyer and Seller; or
 
    (b) by either Seller or Buyer in writing, without liability of the
  terminating party on account of such termination except as set forth in
  paragraph 11.2 (provided the terminating party is not otherwise in breach
  of this Agreement), if the Closing shall not have occurred on or before
  October 31, 1995 because of the failure to satisfy any condition precedent
  to the obligations of the terminating party.
 
11.2 Effect of Expiration or Termination
 
  (a) All obligations of the parties hereunder shall cease upon any expiration
or termination pursuant to paragraph 11.1, provided, however, that (i) the
provisions of this Section 11, paragraph 4.8, paragraph 5.2, paragraph 6.2,
paragraph 14.4, and paragraph 14.13 hereof shall survive any expiration or
termination of this Agreement and (ii) nothing herein shall relieve any party
from any obligations pursuant to subparagraph (b) or (c) below.
 
  (b) Notwithstanding any provision in this Agreement to the contrary, if this
Agreement is terminated by Buyer pursuant to paragraph 11.1(b) above or
expires, Seller shall not have any obligations or liabilities under this
Agreement (except as set forth in paragraph 11.2(a) above and this
subparagraph 11.2(b)); provided, however, that in the event such termination
or expiration is attributable to (i) Seller's failure to satisfy any of the
conditions to Closing described in subparagraphs 7.1(a), 7.1(b), 7.1(c),
7.1(d), 7.1(i), 7.1(j) or 7.1(k) or (ii) Seller's failure to close the
transactions contemplated hereby for any reason other than as permitted by the
terms of this Agreement, then Seller shall pay to Buyer, as liquidated
damages, an amount equal to the sum of $5,000,000. Any amount payable to Buyer
by Seller pursuant to the foregoing sentence shall be paid promptly after
receipt by Seller of a written notice setting forth in reasonable detail the
reason or reasons such amount is payable; provided, however, that in the event
this Agreement expires by reason of Seller's failure to close the transactions
contemplated hereby for any reason other than as permitted by the terms of
this Agreement, such written notice shall be received by Seller no later than
30 days after the expiration date of this Agreement.
 
  (c) Notwithstanding any provision in this Agreement to the contrary, if this
Agreement is terminated by Seller pursuant to paragraph 11.1(b) above or
expires, Buyer shall not have any obligations or liabilities under this
Agreement (except as set forth in paragraph 11.2(a) hereof and this
subparagraph 11.2(c)); provided, however, that in the event such termination
or expiration is attributable to (i) Buyer's failure to satisfy any of the
conditions to Closing described in subparagraphs 7.2(a), 7.2(b), 7.2(d),
7.2(f), 7.2(g), 7.2(h) or 7.2(i) or (ii) Buyer's failure to close the
 
                                     VI-32
<PAGE>
 
transactions contemplated hereby for any reason other than as permitted by the
terms of this Agreement, then Buyer shall pay to Seller, as liquidated
damages, an amount equal to the sum of $5,000,000. Notwithstanding any
provision in this Agreement to the contrary, if this Agreement is terminated
by Buyer pursuant to paragraph 11.1(b) above or expires, Buyer shall not have
any obligations or liabilities under this Agreement (except as set forth in
paragraph 11.2(a) hereof); provided however, that in the event such
termination or expiration is attributable to the failure to satisfy the
condition to Closing described in subparagraph 7.1(h), then Buyer shall pay to
Seller, as liquidated damages, an amount equal to the sum of $5,000,000. Any
amount payable to Seller by Buyer pursuant to the two preceding sentences
shall be paid promptly after receipt by Buyer of a written notice setting
forth in reasonable detail the reason or reasons such amount is payable;
provided, however, that in the event this Agreement expires by reason of
Buyer's failure to close the transactions contemplated hereby for any reason
other than as permitted by the terms of this Agreement, such written notice
shall be received by Buyer no later than 30 days after the expiration date of
this Agreement.
 
  (d) The payment by Seller or Buyer, as the case may be, of $5,000,000 as
provided in subparagraph (b) or (c) above shall constitute liquidated damages
for expiration or termination and shall be the payee's sole remedy for
expiration or termination and upon payment thereof no party hereunder shall
have any liability to or recourse against the other under or on account of
this Agreement, except that nothing contained herein shall affect any party's
obligations as described in subparagraph (a)(i) above.
 
  (e) Neither Buyer nor Seller shall have any liability to or recourse against
the other if this Agreement expires or is terminated because of the failure to
satisfy any of the conditions to Closing described in subparagraphs 7.1(e),
7.1(f), 7.1(g) or 7.1(l), or the failure to satisfy either of the conditions
to Closing described in subparagraphs 7.2(c), 7.2(e) or 7.2(j).

12.1 Dispute Resolution
 
  Any claim, dispute, difference or controversy between or among the parties

described in this Section 12.
 
12.2 Referral to Representatives
 
  (a) The claim, dispute, difference or controversy arising out of or in
relation to this Agreement, shall be subjected first to the procedure in this
paragraph 12.2. Any party may cause a proceeding to be commenced by giving
written notice to all other parties that it desires to do so (the date of such
notice is hereinafter referred to as the "Notice Date"). Each party shall
thereupon prepare a written statement (the "Statement") briefly describing
such party's position with respect to such claim, dispute, difference or
controversy. For purposes hereof, Buyer shall designate a representative and
Seller shall designate a representative (collectively, the "Representatives")
as the individuals who shall represent such parties for purposes of this
paragraph 12.2. The Statement shall be prepared within 15 days of the Notice
Date and given to all parties.
 
  (b) The Representatives shall, during the 15 day period commencing on the
fifteenth day after the Notice Date, meet and negotiate in good faith in an
attempt to resolve such claim, dispute, difference or controversy. If such
attempt proves unsuccessful in the judgment of any party, such
 
                                     VI-33
<PAGE>
 
party may, subject to the terms of this Agreement, pursue any legal remedy
available to such party.

    2.6.5 On a daily basis after performing cash application, Baxter shall

  upon sales of Products made to Industrial Customers under this Agreement
  after the date hereof. If necessary, for the first ten days from the date
  hereof, Baxter shall remit to VWR by wire transfer an amount equal to an
  estimate of such receipts based on a percentage of the historic average
  daily cash collected of accounts receivable from Industrial Customers

  at the end of the first month of the Term, the parties shall calculate the
  difference between: (a) estimated payments made by Baxter to VWR during
  such ten day period; and (b) the actual collections received on account of
  the accounts receivable specified in the first sentence of this Section

  price agreement with Baxter (which may be in writing or may only be
  reflected in Baxter computer system) prior to the date of this Agreement,
  at the price contained in such contract or price agreement, until notified
  by VWR to change such price.
 
    2.6.8 Baxter shall provide VWR with a summary of monthly sales by state
  and local taxing jurisdiction which shall be classified on an exempt and
  non-exempt basis within seven days of month end. VWR shall be responsible
  for filing sales tax returns with the appropriate taxing authorities and
  remitting to them the sales taxes remitted by Baxter to VWR pursuant to
  Section 2.6.5. Baxter shall obtain exemption certificates relating to new
  Industrial Customers during the term of this Agreement. Unless otherwise
  directed by VWR, Baxter shall maintain all appropriate controls and
  administration of all sales tax compliance functions. Baxter shall from
  time to time make available to VWR upon its request detailed
 
                                     VII-3
<PAGE>
 
  sales journals (which it shall maintain by state and local taxing
  jurisdiction) and all copies of all invoices which it has delivered to
  Industrial Customers. In addition, Baxter shall furnish to VWR all state
  tax exemption certificates in its possession relating to all Industrial
  Customers upon the transfer of the applicable accounts receivable

and general office personnel ("VRW Representatives") to the same extent that
the persons employed by Baxter in similar capacities had access to such
facilities immediately prior to the date of this Agreement, and voice mail for
the VWR Representatives using such facilities, the number of such VWR
Representatives not to exceed 569 in the aggregate. If requested by VWR and
agreed to by Baxter, Baxter shall provide to VWR Facilities Services after the
first six months of the Term subject to Section 4.8 herein.
 
3. Term.
 
  Baxter shall render the Services and the Additional Services during the term
of this Agreement ("Term") which shall commence on the date of this Agreement
and terminate no later than two years thereafter. This Agreement shall
terminate with respect to all of the Services or Additional Services on a
Region by Region basis pursuant to the termination schedule which shall be
provided by VWR within 30 days after the date of this Agreement. VWR may
shorten the period during which Services or Additional Services are provided
by Baxter in any Region by giving Baxter 120 days written notice prior to the
effective date of termination of such Services or Additional Services. VWR may
extend the period during which Services or Additional Services are provided to
any Region beyond the applicable termination date in the termination schedule
provided by VWR by giving Baxter 120 days written notice prior to the date of
termination of the Services or Additional Services, provided that such notice
sets forth the time period of such extension, which in no case shall extend
beyond the Term, unless extended by mutual agreement, and the Services or
Additional Services to be provided.
 
4. Consideration.
 
  4.1 In consideration of Baxter providing Services to VWR, VWR shall made
monthly payments to Baxter for such Services ("Services Payments") as set
forth herein, provided that VWR shall not be required to make any Services
Payments during the first three months of this Agreement.
 
  4.2 The Services Payments for the 12 month period from the beginning of the
fourth month through the end of the fifteenth month of the Term shall equal
5.5% of the total sales of the Products to Industrial Customers which are
serviced by Baxter pursuant to the terms of this Agreement ("IC Sales") during
such 12 month period, provided that in no event shall such Services Payments
be less than $18,645,000 in the aggregate during such 12 month period (such
$18,645,000 figure is based on $452,000,000 multiplied by 5.5% multiplied by
9/12). Payments due during such 12 month period shall be due and payable
within 15 days following the end of each such month. If during any quarter
during such 12 month period the difference between: (a) $4,661,250, less (b)
the actual IC Sales made during such quarter multiplied by 5.5% is greater
than zero, then, within 15 days after the end of each such quarter, VWR shall
pay to Baxter an amount equal to such difference.
 
  4.3 If VWR has made payments to Baxter totalling at least $18,645,000
pursuant to Section 4.2 and the difference between: (a) the actual Services
Payments made by VWR during such
 
                                     VII-4
<PAGE>
 
12-month period (including any end-of-quarter payments) pursuant to Section
4.2 exceeds (b) 5.5% multiplied by IC Sales during such 12-month period, then
VWR shall be entitled to a credit ("Credit") equal to such excess, which
Credit shall be applied against Services Payments for Services provided during
each month during the three month period from the beginning of the sixteenth
month through the end of the eighteenth month of the Term.
 
  4.4 The Services Payments for each month during the period from the
beginning of the sixteenth month through the end of the eighteenth month of
the Term shall be actual IC Sales multiplied by 5.5%, provided that any Credit
shall be applied against such Services Payments until such Credit is depleted.
Such Services Payment shall be paid within 15 days of the end of each month
during such period.
 
  4.5 The Services Payments for each month during the period from the
beginning of the nineteenth month through the end of the twenty-fourth month
of the Term shall be 5.5% of actual IC Sales during each such month. Such
Services Payments shall be paid within 15 days of the end of each month during
such period.
 
  4.6 Except as expressly provided herein, no other consideration or
reimbursement shall be payable to Baxter for the Services unless the parties
otherwise agree in writing.
 
  4.7 If Baxter renders any Additional Services to VWR pursuant to the terms
of Section 2.1, VWR shall pay to Baxter in addition to the Services Payments
an amount equal to that set forth in any written agreement providing for such
Additional Services (which the parties acknowledge shall be based upon the
variable cost incurred by Baxter in rendering such Additional Services). Any
such payment for Additional Services shall be paid within 15 days of the end
of each month in which such Additional Services have been rendered.
 
  4.8 If Baxter renders any Facilities Services to VWR after the first six
months of the Term pursuant to the terms of Section 2.7, VWR shall, for each
VWR Representative located at a Baxter facility, pay to Baxter in addition to
the Services Payments $192 per each such VWR Representative per month based on
full-time employment. Baxter shall invoice VWR for such Facilities Services
and specify the number of VWR Representatives and their locations broken out
by full-time and part-time employees. Any such payment for Facilities Services
shall be paid within 15 days of the end of each month during which such
Facilities Services have been rendered.
 
  4.9 If any payments due hereunder have not been received by Baxter within 15
days after the date on which such payments are due, such overdue amounts shall
bear interest from the applicable due date until the date paid at the prime
rate published by the Wall Street Journal as of such applicable due date.
 
  4.10 Notwithstanding anything to the contrary contained herein, if, during
any year during the Term, IC Sales in any Region exceed 125% of the 1994
annual sales level for such Region specified in Exhibit A, Baxter shall not be
obligated to provide any Services to any such Region in connection with any IC
Sales in excess of such 125% amount if the provision of such excess Services
would require Baxter to make any capital expansions.
 
5. Performance of Services.
 
  5.1 Subject to the other provisions of this Section 5, Baxter shall use
reasonable efforts in providing the Services hereunder and shall perform the
Services in a manner consistent with past practice and with the same degree of
care, skill and prudence customarily exercised by Baxter in providing services
similar to the Services to its own operating divisions prior to the date of
this Agreement. Baxter shall stock inventories of the Products at service
levels consistent with those service levels provided by Baxter to the
Industrial Distribution Business prior to the date hereof.
 
                                     VII-5
<PAGE>
 
  5.2 Baxter shall prepare and deliver monthly sales, cost of goods sold,
accounts receivable and other reports as such reports were prepared by Baxter
for the Industrial Distribution Business immediately prior to the date hereof
(collectively, the "Reports"). Baxter shall from time to time upon advance
notice provide VWR and/or its independent public accountants or principal
financial institutions with full access to all accounting and other records
which were used to produce, or in any way support, the Reports in connection
with VWR's business.
 
  5.3 Baxter and VWR shall cooperate in planning the scope and timing of the
Additional Services in order to minimize or eliminate interference with the
conduct of Baxter's business activities.
 
  5.4 In providing the Services, neither Baxter nor its Affiliates shall be
responsible for the accuracy, completeness or timeliness of any advice or
Service or any return, report, filing or other document which it provides,
prepares or assists in preparing, except to the extent that any inaccuracy,
incompleteness or untimeliness arises from the gross negligence or willful
misconduct of Baxter or its Affiliates; provided that in no event, whether as
a result of a breach of this Agreement, tort liability or otherwise, shall
Baxter be liable to VWR for any special, indirect, incidental or consequential
damages. Baxter and its Affiliates shall provide Services with respect to such
returns, reports, filings and other documents with the same timeliness and
accuracy as it prepared such returns, reports, filings and other documents for
the Industrial Distribution Business immediately prior to the date hereof,
provided that Baxter acknowledges that the timeliness of the Reports are
essential to VWR's ability to meet its financial reporting requirements
(including those imposed by the federal securities laws).
 
6. Remittances and Settlement.
 
  6.1 Baxter shall invoice VWR as follows:
 
    6.1.1 2.6% times net IC Sales for the month just ended to cover freight
  from Baxter's shipping point(s) (or manufacturer's facility in the case of
  a drop shipment) to Industrial Customers in the United States; provided,
  however, that Baxter shall credit VWR for any freight collected from
  Industrial Customers.
 
    6.1.2 for Baxter Products delivered by Baxter to fulfill Industrial
  Customers' orders and invoiced during the month just ended. Such Baxter

  Agreement.
 
    6.1.3 for Distributed Products delivered by Baxter to fulfill VWR's
  Industrial Customer orders and invoiced during the month just ended. Such

  computer system (which shall include a factor for inbound freight costs)
  net of applicable vendor rebates.
 
    6.1.4 Baxter shall invoice VWR pursuant to this Section on a daily basis
  and VWR shall pay such invoices by wire transfer within 15 days after the
  date of each such invoice.
 
7. Termination of Services.
 
  7.1 Prior to the date upon which Baxter's performance of Services shall
cease for any Region, Baxter and VWR shall formulate a mutually acceptable
transition plan, including, without limitation, VWR's purchase of Distributed
Products from Baxter as provided for herein. As part of such transition plan,
VWR shall purchase from the Baxter facility that has been servicing customers
in that Region, an inventory of Distributed Products at Baxter's then-current
 
                                     VII-6
<PAGE>
 
merchandise file costs (which shall include a factor for inbound freight
costs) which shall include associated excess, no-move Distributed Products (at
Baxter's book value determined following Baxter's standard policies), all
F.O.B. the Baxter facility. VWR shall pay Baxter the costs for such

Customers of that Region. VWR shall be liable for and shall pay at the time of
the purchase of such Distributed Products all federal, foreign and state sales
taxes and all other sales taxes, duties, documentary stamps, transfer taxes,
registration fees and charges or other like charges properly payable upon and
in connection with the assignment and transfer of such Distributed Products by
Baxter to VWR hereunder. Baxter shall prepare such Distributed Products for
shipment to a VWR location specified by VWR. Pursuant to the implementation of
such transition plan, Baxter shall transfer such Distributed Products as

    7.1.1 Baxter shall provide VWR with a magnetic tape containing the
  catalog numbers of such Distributed Products to be purchased;
 
    7.1.2 Baxter shall conduct a physical count of such Distributed Products
  to be shipped;
 
    7.1.3 Baxter shall prepare such Distributed Products for shipment to a
  specified VWR location pursuant to such transition plan, provided that VWR
  shall be solely responsible for all costs associated with such shipment;
  and
 
    7.1.4 Baxter shall deliver to VWR a detailed invoice (each a "Baxter
  Invoice") for such Distributed Products based upon its physical count which
  contains prices for each such Distributed Product, which invoice, subject
  to Section 7.2. below, shall be final, binding and conclusive on the
  parties hereto.
 
Any adjustments resulting from the physical count (i.e., "ADKS") shall be
provided to VWR within two business days of the reconciliation. VWR shall be
entitled to have its representatives (including its independent auditors)
present during any such physical inventory count.
 
  7.2 VWR, at its own expense, may conduct an audit or review of the amount
set forth on any Baxter invoice, including causing any nationally recognized
firm of independent public accountants designated by VWR to perform such
audit, review or other report. VWR may dispute any
Baxter Invoice from Baxter, but only on the basis that VWR has been invoiced
for Distributed Products at costs other than Baxter's then-current merchandise
file costs (or book value for excess, no-move) or that such Distributed
Products are not in new or saleable condition (except for such no-move). Any
such dispute shall be initiated by written notice delivered to Baxter within
30 days of VWR's receipt of any such Products. Such notice shall specify each
disputed item, the amount thereof and the basis on which such dispute is made.
If Baxter and VWR are unable to reach a written resolution of all disputed
items within 20 days after VWR's written notice of dispute, Baxter and VWR
shall submit the items remaining in dispute for resolution to a firm of
independent public accountants having national standing in the United States
which is not then retained by Baxter, VWR or their respective Affiliates, as
mutually selected by VWR and Baxter (the "Neutral Accounting Firm"). In the
event that Baxter and VWR are unable to agree on the Neutral Accounting Firm,
then a nationally recognized "Big Six" accounting firm shall be selected by
lot after eliminating one such firm selected by Baxter and one such firm
selected by VWR. The Neutral Accounting Firm shall, within 30 days after
submission to it of the disputed items, determine and report in writing to the
parties upon such remaining disputed items in accordance with the provisions
hereof; and such report shall be final, binding and conclusive on the parties
hereto. The fees and disbursements of the Neutral Accounting Firm shall be
allocated between Baxter and VWR in the same proportion that the aggregate
amount of such remaining disputed items so submitted to the Neutral Accounting
Firm that is unsuccessfully disputed by each (as finally determined by the
Neutral Accounting Firm) bears to the total amount of such remaining
 
                                     VII-7
<PAGE>
 
disputed items so submitted. The Neutral Accounting Firm shall make such
determination in its sole discretion, subject to the terms and conditions of
this Agreement; provided, however, that the amount determined by the Neutral
Accounting Firm in respect of any such remaining disputed item shall not
exceed the highest amount claimed by either of the parties disputing such
item, or be less than the lowest amount claimed by either of the parties
disputing such item.
 
  7.3 VWR shall pay each Baxter Invoice, less any disputed amounts subject to
Section 7.2, by wire transfer within 15 days after the date of such Baxter
Invoice.
 
  7.4 Each mutually acceptable transition plan discussed in Section 7.1 shall
contain understandings regarding the delivery of all of Baxter's records,
books, and other data relating exclusively to the Products previously serviced
by Baxter at such Region, including all accounts receivable data.
 
8. Indemnity.
 
  8.1 VWR agrees to indemnify and hold Baxter and the Baxter Indemnified
Parties (as hereinafter defined) harmless from and against, and in respect of,
any and all damages, claims, losses, demands, suits, losses, fines, penalties
and liabilities ("Losses") asserted against or incurred by, and all expenses
(including all reasonable fees and expenses of counsel, travel costs and other
out-of-pocket costs) incurred in connection with pending or threatened
litigation or other proceedings ("Expenses") by, Baxter or any of the Baxter
Indemnified Parties and which arise out of or relate to the provision of
Services hereunder by Baxter or any of the Baxter Indemnified Parties which
arise out of or relate to any claim, action or proceeding asserted by a third
party to the extent arising specifically out of any matter or thing
specifically constituting a breach by VWR hereunder or any wrongful or
negligent act or omission by VWR (or its employees or agents) in its
performance of the terms of this Agreement. The Baxter Indemnified Parties
shall mean and include: (x) Baxter's Affiliates; and (y) the respective
directors, officers, agents and employees of Baxter and its Affiliates.
Expenses shall be reimbursed or advanced when and as incurred promptly upon
submission by Baxter or any Baxter Indemnified Party of statements to VWR.
 
  8.2 Baxter agrees to indemnify and hold VWR and the VWR Indemnified Parties
(as hereinafter defined) harmless from and against, and in respect of, any and
all damages, claims, losses, demands, suits, losses, fines, penalties and
liabilities ("Losses") asserted against or incurred by, and all expenses
(including all reasonable fees and expenses of counsel, travel costs and other
out-of-pocket costs) incurred in connection with pending or threatened
litigation or other proceedings ("Expenses") by, VWR or any of the VWR
Indemnified Parties and which arise out of or relate to the provision of
Services hereunder by VWR or any of the VWR Indemnified Parties which arise
out of or relate to any claim, action or proceeding asserted by a third party
to the extent arising specifically out of any matter or thing specifically
constituting a branch by Baxter hereunder or any wrongful or negligent act or
omission by Baxter (or its employees or agents) in its performance of the
terms of this Agreement. The VWR Indemnified Parties shall mean and include:
(x) VWR's Affiliates; and (y) the respective directors, officers, agents and
employees of VWR and its Affiliates. Expenses shall be reimbursed or advanced
when and as incurred promptly upon submission by VWR or any VWR Indemnified
Party of statements to Baxter.
 
9. Third Party Claims.
 
  If any third party shall make any claim or commence any arbitration
proceeding or suit against any one or more of the Indemnified Persons with
respect to which an Indemnified Person
 
                                     VII-8
<PAGE>
 
intends to make any claim for indemnification against VWR under Section 8.1 or
against Baxter under Section 8.2, such Indemnified Persons shall promptly give
written notice to VWR or Baxter, as the case may be, of such third party
claim, arbitration proceeding or suit and the following provisions shall
apply:
 
  9.1 Subject to Section 9.2, such Indemnified Persons shall have the right to
conduct and control, through counsel of their choosing, the defense of any
third party claim, arbitration proceeding or suit, and such Indemnified
Persons may settle the same; provided that such Indemnified Persons shall give
the indemnifying party advance notice of any proposed settlement. Such
Indemnified Persons shall permit the indemnifying party to participate in the
defense of any such action or suit through counsel chosen by it, provided that
the fees and expenses of such counsel shall be borne by the indemnifying
party. Any settlement with respect to a claim for money damages effected by
such Indemnified Persons after the indemnifying party has notified such
Indemnified Persons in writing of the indemnifying party's disapproval of such
settlement, shall discharge the indemnifying party from liability with respect
to the subject matter thereof under this Agreement, and no claim for
indemnification therefor shall be claimed by such Indemnified Persons under
Section 8.1 or Section 8.2, as the case may be.
 
  9.2 Notwithstanding Section 9.1, if the remedy sought in any claim,
arbitration proceeding or suit referred to in this Section 9 is solely money
damages, the indemnifying party shall have 15 business days after receipt of
the notice referred to above in this Section 9 to notify such Indemnified
Persons that it elects to conduct and control the defense of such claim,
proceeding or suit. If the indemnifying party does not give the foregoing
notice, such Indemnified Persons shall have the right to defend or settle such
claim, proceeding or suit in the exercise of their exclusive discretion, and
the indemnifying party shall, upon request from any of such Indemnified
Persons, promptly pay to them in accordance with Section 8.1 or Section 8.2,
as the case may be, the amount of any liabilities, damages, losses and
expenses, including reasonable attorney's fees, resulting from such claim,
proceeding or suit. If the indemnifying party gives the foregoing notice, the
indemnifying party shall have the right to undertake, conduct and control,
through counsel of its own choosing and at the sole expense of the
indemnifying party, the conduct and control of the defense and any settlement
of such claim, proceeding or suit, and such Indemnified Persons shall
cooperate with the indemnifying party in connection therewith; provided that:
(a) the indemnifying party shall not thereby permit to exist any lien,
encumbrance or other adverse charge upon any asset of any of such Indemnified
Persons; (b) the indemnifying party shall permit such Indemnified Persons to
participate in such defense or settlement through counsel chosen by such
Indemnified Persons, but the fees and expenses of such counsel shall be borne
by such Indemnified Persons except as provided in clause (c) below; and (c)
the indemnifying party shall agree to reimburse promptly under Section 8.1 or
Section 8.2, as the case may be, such Indemnified Persons for the full amount
of any liabilities, damages, losses and expenses, including reasonable
attorneys' fees, resulting from such claim, proceeding or suit, except in each
case for any fees and expenses of counsel for such Indemnified Persons
incurred after the assumption of the conduct and control of such claim,
proceeding or suit by the indemnifying party. So long as the indemnifying
party is contesting any such claim, proceeding or suit in good faith, such
Indemnified Persons shall not pay or settle any such claim, proceeding or
suit; provided, however, that such Indemnified Persons shall have the right to
pay or settle any such claim, proceeding or suit; provided, further, that in
such event such Indemnified Persons shall be deemed to have waived any right
to indemnity therefor by the indemnifying party under Section 8.1 or Section
8.2, as the case may be.
 
10. Confidentiality.
 
  10.1 Each of Baxter and VWR undertakes to the other, on behalf of itself and
its employees, officers, directors, agents and Affiliates, that it shall keep
confidential and shall not, without the
 
                                     VII-9
<PAGE>
 
prior written consent of the party to whom the information relates, disclose
to any person, nor use or exploit commercially for its own purposes, any
information obtained relating to the subject matter or performance of this
Agreement; provided, however, that each of Baxter and VWR may disclose such
information: (a) to its Affiliates for any purposes reasonably incidental to
the purposes of this Agreement; (b) to its respective advisors for use in
connection with rendering advice with respect to the performance of this
Agreement; and (c) as is required to be disclosed by operation of law, legal
process or any stock exchange regulations or any binding judgment or order, or
by any requirement of any competent, federal, provincial, state, local or
foreign court, administrative agency or governmental or regulatory authority
or body. In performing its obligations under this Section 10.1, each of Baxter
and VWR shall use all reasonable efforts to ensure that its employees,
officers, directors and agents and Affiliates observe the foregoing
confidentiality obligations.
 
  10.2 Section 10.1 shall not apply to information:
 
    10.2.1 acquired from a third party with the right to divulge the same;
 
    10.2.2 which, prior to or after the date of this Agreement, Baxter and
  VWR jointly decided to disclose; or
 
    10.2.3 which is or becomes within the public domain (otherwise than
  through the fault of the recipient party).
 
11. Suspension/Termination.
 
  Baxter may suspend the provision of any Services, Additional Services or
Facilities Services for which payment has not been received within 30 days
following the date on which such payment is due until such payments have been
received by Baxter and any such failure to pay within such 30-day period shall
be considered a material default hereunder, provided that the foregoing shall
not apply to any portion of any invoice that is disputed in good faith by VWR.
Either party shall have the right to terminate this Agreement effective upon
delivery of written notice to the other party if the other party: (a) makes an
assignment for the benefit of creditors, or becomes bankrupt or insolvent, or
is petitioned into bankruptcy, or takes advantage of any federal, provincial
or foreign bankruptcy or insolvency act, or if a receiver or receiver/manager
is appointed for all or any substantial part of its property and business and
such receiver or receiver/manager remains undischarged for a period of 30
days, or if the corporate existence of the other party is terminated by
voluntary or involuntary dissolution; or (b) materially defaults in the
performance of any of its convenants or obligations contained in this
Agreement and such default is not remedied to the non-defaulting party's
reasonable satisfaction within 30 days after written notice to the defaulting
party of such default, or if such default is not capable of rectification
within 30 days, if the defaulting party has not promptly commenced to rectify
the default within such 30-day period, and thereafter proceeds diligently to
rectify same, provided that such right of rectification shall not extend the
Term as provided in Section 3.
 
12. Non-Exclusivity.
 
  Nothing in this Agreement shall preclude VWR from obtaining the Services, in
whole or in part, from its own employees or from providers other than Baxter
at any time; provided that VWR shall be responsible for paying to Baxter
Services Payments as provided for herein. Subject to the terms and conditions
of Section 4.11 of the Asset Purchase Agreement, nothing shall preclude Baxter
or any of its Affiliates from providing services comparable to the Services to
any other person or entity at any time.

negotiations, commitments and writings with respect to such subject matter.
 
  14.2 This Agreement shall be governed by and construed and enforced in
accordance with the laws of the State of Illinois and the federal laws of the
United States of America applicable therein. Any lawsuit arising from or
related to this Agreement shall be brought before the United States District
Court for the Northern District of Illinois or the Eastern District of
Pennsylvania or an Illinois state court sitting in Lake County, Illinois, or
any Commonwealth Court sitting in Chester County, Pennsylvania. The parties
hereby consent to the jurisdiction of such courts.

and validly executed by each party hereto, or in the case of a waiver, the
party waiving compliance.
 
                                    VII-11
<PAGE>
 
  14.4 This Agreement shall be binding upon and enure to the benefit of the
parties hereto and their respective successors and assigns, provided, however,
that neither party shall have the right to transfer or assign its interest in
this Agreement without the prior written consent of the other party, which
consent shall not be unreasonably withheld.
 
    14.4.1 Notwithstanding the foregoing, either party may assign its rights
  and obligations, in whole or in part, to any Affiliate provided that the
  assigning party guarantees performance by such Affiliate.
 
    14.4.2 Notwithstanding the foregoing provisions of this Section 14.4,
  Baxter may assign its rights and obligations under this Agreement to any
  corporation or other entity that shall acquire all or substantially all of
  Baxter's business and assets and who shall assume in writing all of
  Baxter's obligations hereunder and deliver a signed copy of such assumption
  instrument to VWR; provided, further, that upon VWR's receipt of such

    14.4.3 Notwithstanding the foregoing provisions of this Section 14.4, to
  the extent that any corporation or other entity shall acquire all or
  substantially all of Baxter's business and assets relating to any of the
  Products, Baxter may assign a corresponding portion of its rights hereunder

provisions or the enforceability of this Agreement.
 
  14.7 The failure at any time of either party to require performance by the
other party of any responsibility provided for in this Agreement shall in no
way affect the right to require full performance of any such responsibility at
any time thereafter, nor shall the waiver by either party of a breach of any
provision of this Agreement by the other party constitute a waiver of any
succeeding breach of the same or any other provision nor shall it constitute a
waiver of the responsibility itself.
 
  14.8 Baxter is acting as an independent contractor in connection with
providing the Services and neither party constitutes the other as its agent,
partner, joint venturer, or legal representative or has express or implied
authority to bind the other in any manner whatsoever. All employees and
representatives of Baxter providing the Services to VWR shall be deemed for
purposes of all compensation and employee benefits to be employees or
representatives of Baxter and not employees or representatives of VWR. In
performing the Services, such employees and representatives shall be under the
direction, control and supervision of Baxter (and not of VWR) and Baxter shall
have the sole right to exercise all authority with respect to the employment
(including termination of employment), assignment and compensation of such
employees and representatives.

be excused during each period of delay caused by matters (not including lack

shortages of raw materials, government orders or acts of
 
                                    VII-12
<PAGE>
 
God, which are reasonably beyond the control of the party obligated to perform.
Any delay occasioned thereby shall not constitute a default under this
Agreement, and the obligations of the parties shall be suspended during the
period of delay so occasioned.
 
  IN WITNESS WHEREOF, the parties have by their duly authorized officers
executed this Agreement as of the date first above written.

  1. Distributor, Supplier, and EM Laboratories, Incorporated, a New York

May 24, 1995 pursuant to which Supplier has sold to Distributor, and
Distributor has purchased from Supplier, certain of the assets and business of
Supplier's "Industrial Distribution Business," as defined in the Asset

                                   AGREEMENT
 
  In consideration of the Asset Purchase Agreement and the mutual covenants
contained herein, and for other good and valuable consideration, the receipt
and sufficiency of which is hereby acknowledged, Supplier and Distributor
agree as follows:
 
1. Definitions.
 
  1.1 "Affiliate" shall mean any person, firm or corporation controlling,
controlled by or under direct or indirect common control with a party hereto.
For the purpose of this definition, the term "control" means the power to

through the ownership of voting securities, by contract or otherwise; and the
terms "controlling" and "controlled" have meanings correlative to the
foregoing.
 
  1.2 "Contract Year" shall mean the period commencing on October 1 and ending

2. Distribution Rights.
 
  2.1 During the Term, as defined herein, Supplier hereby grants to
Distributor, and Distributor accepts the right to sell and distribute the
Products only to Industrial Customers in the Territory for non-patient use
subject to the terms and conditions stated herein. Distributor may grant to EM
or its Affiliates the rights to distribute the Products outside the United
States, provided that with respect to such distribution, EM shall be subject
to all of Distributor's duties and obligations hereunder (except for the
Minimum Purchase Requirements) and Distributor shall remain fully liable for
EM's performance of such duties and obligations. During the Term, except as
otherwise provided in Section 2.3, Supplier and its Affiliates shall
distribute the Products to Industrial Customers in the Territory only through
Distributor pursuant to this Agreement.
 
  2.2 Distributor hereby accepts such grant of distribution rights.
Distributor represents and warrants that it shall not sell or distribute the
Products other than as provided for herein. Distributor hereby agrees that
during the Term:
 
    2.2.1 none of Distributor or its respective Affiliates, or any other
  Person on its or their behalf, shall sell, solicit orders for or otherwise

  or otherwise, to or from any customer or any Affiliate of any customer: (a)
  located outside of the Territory; (b) that is not an Industrial Customer;
  or (c) for any use other than non-patient use;
 
    2.2.2 Distributor may distribute Products in the Territory through sub-

  of the dollar volume of all Products sold by Distributor during such
  Contract Year in the United States; and
 
    2.2.3 Supplier shall not be responsible to the extent Distributor grants
  any warranty, service contract or similar right with respect to the
  Products that is different from or additional to the warranty set forth in

  consent may be withheld by Supplier in its sole discretion. To the extent
  that Distributor or any of its Affiliates grants, or is deemed to have
  granted, any such warranty or right, Distributor shall be solely
  responsible therefor, it being understood that the purpose of this sentence
  is to allocate responsibility between Distributor and Supplier and not with
  respect to any other party.
 
  2.3 Distributor acknowledges and agrees that:
 
    2.3.1 this Agreement shall not prohibit Supplier or its Affiliates from
  distributing the Products to Industrial Customers within the Territory
  otherwise than through Distributor to the extent that Distributor shall be

  unable to sell, the Products to any customer or class of customers,
  provided that such sales shall be credited against the Minimum Purchase
  Requirements for the applicable Contract Year or Stub Period;
 
    2.3.2 Supplier may continue to distribute the Products in the Territory
  to Industrial Customers during the Term: (a) by any means by which Supplier
  distributed the Products, other than through the Industrial Distribution
  Business, prior to the date of this Agreement; or (b) through sub-
  distributors used by Supplier prior to the date of this Agreement; and
 
    2.3.3 Supplier may: (a) continue to sell and distribute the Products in
  the Territory via any means to customers other than Industrial Customers;
  (b) sell and distribute the Products to any customer for non-patient use if

  Minimum Purchase Requirements in the applicable Contract Year or Stub
  Period.
 
3. Term.
 
  The initial term ("Term") of this Agreement shall begin on the date of this
Agreement and end on September 30, 2000; provided that the Term shall be
automatically renewed for additional and successive periods of one year each,
unless and until such initial or additional Term is terminated as provided in
Section 9 of this Agreement.
 
4. Minimum Purchase Requirements.
 
  4.1 Supplier and Distributor acknowledge and agree that the Minimum Purchase
Requirements for Products for the Stub Period and the first five Contract
Years are set forth in Exhibits B and C. The total Minimum Purchase
Requirement for Distributor's U.S. sales for each Contract Year and the Stub
Period shall be the sum of the Base amount plus the Incremental amount listed
on Exhibit B for each such Contract Year or Stub Period. The total Minimum
Purchase Requirement for Distributor's international sales for each Contract
Year and the Stub Period is the incremental amount listed on Exhibit C.
 
  4.2 The Minimum Purchase Requirements for each Contract Year after the fifth
Contract Year, if any, shall be reviewed and established by Distributor and
Supplier on an annual basis through good faith negotiations which shall begin
six months prior to the beginning of each such Contract Year and be completed
at least 60 days prior to the beginning of the applicable Contract Year,
provided that in no event shall any Minimum Purchase Requirement for any
Contract Year be less than such Minimum Purchase Requirement for the previous
Contract Year.
 
  4.3 In the event that the actual dollar amount of the Products purchased by
Distributor in any Contract Year or the Stub Period (the "Actual Purchase
Amount") is less than any Minimum Purchase Requirement for such Contract Year
or Stub Period, Distributor shall, within 30 days after the end of such
Contract Year or Stub Period, either: (a) pay to Supplier as liquidated
damages the difference between the Minimum Purchase Requirement and the Actual
Purchase
 
                                    VIII-3
<PAGE>
 
Amount (the "Purchase Shortfall"); or (b) order and pay for Products in a
dollar amount equal to such Purchase Shortfall.
 
  4.4 Notwithstanding anything to the contrary contained herein, the parties
agree that if, at the end of the third Contract Year, Supplier determines, in
its sole and absolute discretion, that there has been a significant change in
manufacturing processes in clean room environments since the date of this
Agreement, Supplier shall propose revised Minimum Purchase Requirements for
the fourth and fifth Contract Years to address such change.
 
  4.5 If with respect to Distributor's international sales: (a) Distributor's
actual sales during any Contract Year are greater than or less than (b) the
Minimum Purchase Requirement for such Contract Year as set forth in Exhibit C,
the Minimum Purchase Requirement for the following Contract Year shall be
adjusted upward (in the event such sales are greater) or downward (in the
event such sales are less) by the percentage of such shortfall or overage.
 
  4.6 During the first Contract Year and the Stub Period, the mix of
Distributor's purchases of Products shall be of similar proportion to the mix
of such Products sold by the Industrial Distribution Business in 1994. After
the first Contract Year, the mix of Distributor's purchases of Products shall
be of similar proportion to the mix of such Products purchased by Distributor
during the immediately preceding Contract Year. Twice during each Contract
Year, the parties shall meet to determine whether the mix of Distributor's
purchases of Products varies by more than 10% of the mix from the period
against which such Contract Year is measured. If Supplier's margin is
adversely affected by such mix, Supplier shall have the right to revise and
adjust margins in order to eliminate any detrimental effect from such mix on
future sales.
 
  4.7 During the Stub Period and the first Contract Year, Distributor shall
use good faith efforts to achieve the purchase goals specified in Exhibit D,
provided, however, that Distributor shall incur no liability for its failure
to achieve any such purchase goals in excess of any Minimum Purchase
Requirements.
 
5. Prices.
 
  5.1 The prices for each Product sold by Supplier to Distributor under this
Agreement shall be the price set forth opposite such Product in Exhibit A.
Supplier may increase or decrease the price of any Product upon not less than
60 days written notice to Distributor effective on the first day of any
calendar year, provided that such price increase shall be based upon the
constant volume "standard to standard" cost change for Supplier's
manufacturing units producing the Pharmaseal and Convertors Products. Any such
notice shall contain the specific price change for each Product affected by
the notice. Upon the first day of the calendar year immediately following the
expiration of such 60 day period, Exhibit A shall be deemed to be amended to
reflect the price increases and/or decreases contained in such notice without
any further act by any party hereto. Supplier shall honor Distributor's
purchase orders received by Supplier prior to Distributor's receipt of any
such notice at the prices in effect when such orders were received.
Distributor agrees that the dollar volume of its Product purchases during the
60 days prior to the effective date of a price change shall not exceed 20% of
the dollar volume of Distributor's Product purchases during the preceding 10
months, except that such 20% limit shall not apply to purchases made by
Distributor for the sole purpose of achieving any Minimum Purchase
Requirement.
 
    5.1.1 If Distributor exceeds the Minimum Purchase Requirement for the
  Stub Period listed on Exhibit B, Supplier shall pay Distributor a rebate of
  5.9% times the net purchase price of all Products purchased during such
  Stub Period in excess of such Minimum Purchase Requirement.
 
 
                                    VIII-4

    5.1.2 Beginning on October 1, 1995, if at any time during any of the
  first three calendar quarters of any Contract Year, Distributor purchases
  from Supplier more than $12,000,000 of Products, Supplier shall pay
  Distributor a rebate of 5.9% times the net purchase price of all Products
  purchased during such quarter in excess of $12,000,000 subject to Section
  5.1.3.
 
    5.1.3 After the end of each Contract Year Supplier shall calculate
  Distributor's total net purchases of Products and Distributor shall be
  entitled to a rebate of 5.9% times the net purchase price of all Products
  purchased during such Contract Year in excess of $48,000,000. If the
  rebates due Distributor for such Contract Year exceed the rebates paid to
  Distributor during the Contract Year, pursuant to Section 5.1.2 Supplier
  shall pay Distributor such remaining rebate due Distributor. To the extent
  rebates paid for the Contract Year pursuant to Section 5.1.2 exceed the
  total due to Distributor for such Contract Year, Distributor shall repay to
  Supplier the rebate overpayment. If Distributor's total net purchases of
  Products during such Contract Year totalled less than $48,000,000,
  Distributor shall repay all rebates paid by Supplier for the Contract Year
  pursuant to Section 5.1.2.
 
    5.1.4 All rebates due Distributor shall be paid within fifteen (15) days
  after the end of the applicable quarter. All rebate repayments due to
  Supplier shall be paid within fifteen (15) days after the date of
  Supplier's invoice for any repayments due.
 
  5.2 Distributor shall have the exclusive right to establish and control
prices on the Products sold to its customers.
 
  5.3 The prices for the Products sold by Supplier to Distributor shall not
include any transportation expenses, customs duties, sales tax, goods and
services tax or any other sales, use, inventory, delivery, value added or like
taxes of any federal, state or local government in the Territory or anywhere
else, however imposed. Distributor shall be responsible for all such expenses,
duties and taxes and shall pay Supplier any and all taxes which Supplier is
required to collect or pay with respect to the sale to Distributor, of the
Products pursuant to this Agreement.

good and marketable title free of all liens and encumbrances and that are in
good, resalable condition in their original packaging and are not obsolete.
The purchase price of such inventory shall be equal to the purchase price
thereof paid by Distributor to Supplier, less any reserves for over-stocked or
slow-moving inventory maintained by Distributor in the ordinary course of
business and a restocking fee equal to 10% of Distributor's purchase price
thereof, provided that Supplier may deduct from any amount owed by Supplier

Volume Difference. Notwithstanding the foregoing provisions on this Section
10.2, if, on the date of expiration or termination of this Agreement,
Distributor shall be in default in the performance of any of its covenants or
obligations contained in this Agreement, or if this Agreement shall be
terminated by Supplier in accordance with Section 9 hereof, Supplier shall
have no obligation to purchase any of Distributor's inventory of Products

within the Territory from and after the effective date of the expiration or
termination of this Agreement.
 
11. Force Majeure.
 
  The obligations of either party to perform under this Agreement shall be
excused during each period of delay caused by matters (not including lack of
funds or other financial causes) such as strikes, supplier delays, shortages
of raw materials, government orders or acts of God, which are reasonably
beyond the control of the party obligated to perform. Any delay occasioned
thereby shall not constitute a default under this Agreement, and the
obligations of the parties shall be suspended during the period of delay so
occasioned.
 
12. Confidentiality.
 
  12.1 Supplier agrees that, pursuant to this Agreement, valuable marketing
information of a confidential nature pertaining to the marketplace in the
Territory may be disclosed by Distributor to Supplier; that such information
shall be retained by Supplier in confidence; and that Supplier shall not,
either during the term of this Agreement or thereafter, publish or disclose or
cause anyone else to publish or disclose any marketing information supplied to
Supplier by Distributor. Notwithstanding the foregoing provisions of this
Section 12, the above restrictions on disclosure and use shall not apply to

the time of receipt thereof from Distributor or which may subsequently be
obtained from sources other than Distributor who are not bound by a
confidentiality agreement with Distributor.

marketing, sales or technical information of a confidential nature may be
disclosed by Supplier to Distributor; that such information shall be retained

information supplied to Distributor by Supplier. Notwithstanding the foregoing
provisions of this Section 12.2, the above restrictions on disclosure and use

evidence was known to it at the time of receipt thereof from Supplier or which
may subsequently be obtained from sources other than Supplier who are not
bound by a confidentiality agreement with Supplier.
 
  12.3 Each party acknowledges that the other party would not have any
adequate remedy at law for the breach by either party of any one or more of
the covenants contained in this Section 12 and agrees that, in the event of
such breach, the other party may, in addition to the other remedies which may
be available to it, file a suit in equity to enjoin the breaching party from
any further breach of any of the terms of this Section 12.
 
13. Third Party Claims.
 
  If any third party shall make any claim or commence any arbitration
proceeding or suit against any one or more of the Indemnified Persons with
respect to which an Indemnified Person intends to make any claim for
indemnification against Distributor under Section 6.15 or against Supplier
under Section 7.8, such Indemnified Persons shall promptly give written notice
to Distributor or Supplier, as the case may be, of such third party claim,
arbitration proceeding or suit and the following provisions shall apply:
 
 
                                    VIII-12
<PAGE>
 
  13.1 Subject to Section 13.2, such Indemnified Persons shall have the right
to conduct and control, through counsel of their choosing, the defense of any
third party claim, arbitration proceeding or suit, and such Indemnified
Persons may settle the same; provided that such Indemnified Persons shall give
the indemnifying party advance notice of any proposed settlement. Such
Indemnified Persons shall permit the indemnifying party to participate in the
defense of any such action or suit through counsel chosen by it, provided that
the fees and expenses of such counsel shall be borne by the indemnifying
party. Any settlement with respect to a claim for money damages effected by
such Indemnified Persons after the indemnifying party has notified such
Indemnified Persons in writing of the indemnifying party's disapproval of such
settlement, shall discharge the indemnifying party from liability with respect
to the subject matter thereof under this Agreement, and no claim for
indemnification therefor shall be claimed by such Indemnified Persons under
Section 6.15 or Section 7.8, as the case may be.
 
  13.2 Notwithstanding Section 13.1, if the remedy sought in any claim,
arbitration proceeding or suit referred to in this Section 13 is solely money
damages, the indemnifying party shall have 15 business days after receipt of
the notice referred to above in this Section 13 to notify such Indemnified
Persons that it elects to conduct and control the defense of such claim,
proceeding or suit. If the indemnifying party does not give the foregoing
notice, such Indemnified Persons shall have the right to defend or settle such
claim, proceeding or suit in the exercise of their exclusive discretion, and
the indemnifying party shall, upon request from any of such Indemnified
Persons, promptly pay to them in accordance with Section 6.15 or Section 7.8,
as the case may be, the amount of any liabilities, damages, losses and
expenses, including reasonable attorney's fees, resulting from such claim,
proceeding or suit. If the indemnifying party gives the foregoing notice, the
indemnifying party shall have the right to undertake, conduct and control,
through counsel of its own choosing and at the sole expense of the
indemnifying party, the conduct and control of the defense and any settlement
of such claim, proceeding or suit, and such Indemnified Persons shall
cooperate with the indemnifying party in connection therewith; provided that:
(a) the indemnifying party shall not thereby permit to exist any lien,
encumbrance or other adverse charge upon any asset of any of such Indemnified
Persons; (b) the indemnifying party shall permit such Indemnified Persons to
participate in such defense or settlement through counsel chosen by such
Indemnified Persons, but the fees and expenses of such counsel shall be borne
by such Indemnified Persons except as provided in clause (c) below; and (c)
the indemnifying party shall agree to reimburse promptly under Section 6.15 or
Section 7.8, as the case may be, such Indemnified Persons for the full amount
of any liabilities, damages, losses and expenses, including reasonable
attorneys' fees, resulting from such claim, proceeding or suit, except in each
case for any fees and expenses of counsel for such Indemnified Persons
incurred after the assumption of the conduct and control of such claim,
proceeding or suit by the indemnifying party. So long as the indemnifying
party is contesting any such claim, proceeding or suit in good faith, such
Indemnified Persons shall not pay or settle any such claim, proceeding or
suit; provided, however, that such Indemnified Persons shall have the right to
pay or settle any such claim, proceeding or suit; provided, further, that in
such event such Indemnified Persons shall be deemed to have waived any right
to indemnity therefor by the indemnifying party under Section 6.15 or Section
7.8, as the case may be.
