                          FILED PURSUANT TO RULE 13d-1
                   OF THE GENERAL RULES AND REGULATIONS UNDER
                 THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

This  Amendment No. 4, which  relates to shares of the common  stock,  par value
$1.00 per share (the "Common Stock") of VWR Scientific Products Corporation (the
"Issuer") and is being filed by EM Laboratories,  Inc. ("EML"),  supplements and
amends the statement on Schedule 13D originally  filed with the  Commission,  as
amended.

Item 4.  Purpose of the Transaction.

Item 4 is amended as follows:

As previously  reported in this Schedule 13D,  under the terms of the Standstill
Agreement dated February 27, 1995, as amended,  among the Issuer, EM Industries,
Incorporated  and  EML,  EML and its  affiliates  may not  (subject  to  certain
exceptions  specified  therein) acquire  additional  shares of the Issuer except
pursuant to a tender offer recommended,  prior to commencement  thereof,  to the
stockholders of the Issuer by a majority of the directors of the Issuer who have
not  been  designated  for  nomination  by EML.  The  terms  of such  Standstill
Agreement  also  require  that any such offer be made for a cash price to all of
the  stockholders  of the Issuer and that it be  accepted  by the holders of not
less a majority  of the Common  Stock of the Issuer,  excluding  any such shares
held by EML or any affiliate thereof.

On June 8, 1999, Merck KGaA, the ultimate parent company of EML,  announced that
EML had entered into an Agreement  and Plan of Merger,  dated as of June 8, 1999
(the "Merger Agreement"), by and among EML, EM Subsidiary,  Inc., a Pennsylvania
corporation and wholly owned subsidiary of EML ("Sub"), and the Issuer.

Pursuant to the terms of the Merger Agreement,  Sub will commence a tender offer
(the "Offer") to acquire all of the Common Stock not  currently  held by EML and
its  affiliates  for $37.00 per share (the "Offer  Price"),  to be followed by a
merger  (the  "Merger")  in which  any  remaining  stock of the  Issuer  will be
exchanged for cash at the same per share price paid in the Offer.

The Offer will be  conditioned  upon,  among  other  things,  there  having been
validly tendered and not withdrawn prior to the expiration of the Offer a number
of shares of Common  Stock that  represents  a majority  of the total  number of
outstanding shares of Common Stock,  excluding any shares held by Parent, Sub or
any  affiliate  thereof,  as well as the  expiration of any  applicable  waiting
period  under  the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976,  as
amended,  and compliance with Section 721 of Title VII of the Defense Production
Act of  1950,  as  amended,  known  as the  Exon-Florio  provisions,  and  other
customary conditions.

Concurrently  with the  execution of the Merger  Agreement,  EML and Sub entered
into a  Shareholders  Agreement,  dated as of June 8,  1999  (the  "Shareholders
Agreement"),  with Jerrold B. Harris and N. Stewart Rogers (the  "Shareholders")
pursuant to which the Shareholders  have agreed,  among other things, to tender,
in  accordance  with the terms of the Offer,  and not  withdraw,  subject to the
terms of the Shareholders  Agreement,  all of the shares of Common Stock held by
the  Shareholders.  The  shares  held  by  the  Shareholders  represent,  in the
aggregate,  approximately  2.5% of the total  issued and  outstanding  shares of
Common  Stock on a fully  diluted  basis  (assuming  exercise of all options and
other rights to purchase such shares).


                                     3
<PAGE>


Pursuant to the Shareholders  Agreement,  the  Shareholders  have also agreed to
grant EML and Sub an irrevocable proxy to vote their respective shares of Common
Stock in favor of the  Merger;  provided,  however,  that  such  proxies  may be
revoked  in the event that the  Company's  unaffiliated  directors,  that is the
directors not designated by EML,  withdraw their approval and  recommendation of
the  Offer,  the  Merger or Merger  Agreement  or any  transaction  contemplated
thereby.

Sub will obtain funds to consummate  the Offer and the Merger  through a capital
contribution or a loan or a combination thereof from Merck KGaA, EML, or another
affiliate or other  affiliates of Merck KGaA.  The Offer is not  conditioned  on
obtaining financing.  The foregoing is qualified in its entirely by reference to
the copies of the Merger  Agreement and the  Shareholders  Agreement,  which are
filed herewith as exhibits and incorporated herein by reference.



Item 6. Contracts, Arrangements, Understandings or Relationships with
Respect to Securities of the Issuer.

Item 6 is amended as follows:

As described  above in Item 4, on June 8, 1999,  EML, Sub and the Issuer entered
into the Merger Agreement and EML and Sub entered in the Shareholders  Agreement
with the  Shareholders,  both of which agreements are filed herewith as exhibits
and incorporated herein by reference.

Item 7. Material to be Filed as Exhibits.

Exhibit A.   Agreement and Plan of Merger, dated June 8, 1999, among EM
Laboratories, Incorporated, EM Subsidiary,  Inc. and VWR
Scientific Products Corporation.

Exhibit B   Shareholders Agreement, dated June 8, 1999, among EM Laboratories,

approved  the  acquisition  of the Company by Parent on the terms and subject to
the conditions set forth in this Agreement;

WHEREAS,  in furtherance of such  acquisition,  Parent  proposes to cause Sub to
make a cash tender  offer (as it may be amended  from time to time as  permitted
under this Agreement,  the "Offer") to acquire all of the issued and outstanding
shares of Common Stock,  par value $1.00,  of the Company (the "Shares")  (other
than Shares owned by Parent or any Affiliate  thereof and excluding Shares owned
by the  Company or by any  Subsidiary  of the  Company)  at a purchase  price of
$37.00 per Share (such purchase  price being referred to as the "Offer  Price"),
net to the seller in cash, without interest thereon,  upon the terms and subject
to the conditions set forth in this Agreement;  and the  Unaffiliated  Directors
have unanimously adopted resolutions approving the Offer, this Agreement and the
Merger and  recommending  that the Company's  shareholders  accept the Offer and
adopt this Agreement;

WHEREAS,  the  respective  Boards of  Directors of Sub and the Company have each
approved  the merger of Sub with and into the Company (the  "Merger"),  upon the
terms and subject to the conditions set forth in this Agreement, whereby each of
the Shares, other than Shares owned directly or indirectly by Parent, Sub or the
Company and Dissenting  Shares,  will be converted into the right to receive the
price per Share paid in the Offer;

WHEREAS,  the Unaffiliated  Directors have unanimously approved the terms of the
Shareholders  Agreement  (the  "Shareholders  Agreement")  to be entered into by
Parent, Sub and certain holders of Shares,  pursuant to which such holders have,
among other things, agreed to vote such shares in favor of the Merger and tender
such shares pursuant to the Offer; and

WHEREAS,  Parent,  Sub and the Company  desire to make certain  representations,
warranties, covenants and agreements in connection with the Offer and the Merger
and also to prescribe various conditions to the Offer and the Merger.

NOW,  THEREFORE,  in consideration of the foregoing and the mutual covenants and
agreements herein contained,  and intending to be legally bound hereby,  Parent,
Sub and the Company hereby agree as follows:

                              ARTICLE I - THE OFFER

Section 1.1. The Offer.

(a) Provided that this  Agreement  shall not have been  terminated in accordance
with Section 9.1, and subject to the provisions of this  Agreement,  as promptly
as  practicable  but in no event later than five business days after the date of
the public announcement by Parent and the Company of this Agreement,  Sub shall,
and Parent shall cause Sub to,  commence the Offer.  The offer to purchase which
is sent to the Company's shareholders in connection with the Offer shall provide
for an  initial  expiration  date for the Offer (the  "Expiration  Date"") of 20
business days (as defined in Rule 14d-1 under the Exchange Act) from the date of
commencement of the Offer.  The obligation of Sub to, and of Parent to cause Sub
to, commence the Offer and accept for payment,  and pay for, any Shares tendered
pursuant  to the Offer  shall be  subject  only to the  conditions  set forth in
Exhibit A (the "Offer Conditions") (all of which are for the benefit of, and may
be  asserted  by Sub  regardless  of the  circumstances  giving rise to any such
condition  and any of which may be waived in whole or in part by Sub in its sole
discretion, provided that, without the prior written consent of the Company, Sub
shall not waive the Minimum  Condition (as defined in Exhibit A)). Sub expressly
reserves the right to modify the terms of the Offer,  except  that,  without the
prior  written  consent of the  Company,  Sub shall not (i) reduce the number of
Shares to be purchased in the Offer,  (ii) reduce the Offer Price,  (iii) impose
any  conditions  to the Offer in addition to the Offer  Conditions or modify the
Offer  Conditions  (other than to waive any Offer  Conditions  to the extent not
prohibited  by this  Agreement),  (iv) except as provided in the next  sentence,
extend the Offer, (v) change the form of  consideration  payable in the Offer or
(vi) make any other change or  modification  in any of the terms of the Offer in
any  manner  that is  adverse to the  holders  of  Shares.  Notwithstanding  the
foregoing, Sub may, without the consent of the Company, (i) extend the Offer, if
at the Expiration Date or extended expiration date of the Offer any of the Offer
Conditions shall not be satisfied or waived,  until such time as such conditions
are  satisfied or waived,  (ii) extend the Offer for any period  required by any
rule,  regulation,  interpretation  or position of the SEC or the staff  thereof
applicable to the Offer and (iii) on one or more occasions, extend the Offer for
a period of up to an aggregate of 15 business days if, on a scheduled expiration
date on which the Offer  Conditions  shall have been  satisfied  or waived,  the
number of Shares that have been validly  tendered and not withdrawn  pursuant to
the  Offer,  when taken  together  with the  Shares  owned by Parent,  Sub or an
Affiliate  thereof  do not  constitute  at  least  80% of the  then  issued  and
outstanding Shares.  Parent and Sub agree that Sub shall not terminate the Offer
between  scheduled  expiration dates (except in the event that this Agreement is
terminated  pursuant  to  Section  9.1) and that,  in the  event  that Sub would
otherwise be entitled to terminate  the Offer at any scheduled  expiration  date
thereof due to the failure of one or more of the Offer  Conditions,  unless this
Agreement  shall have been  terminated  pursuant to Section 9.1, Sub shall,  and
Parent  shall  cause  Sub to,  extend  the  Offer  until  such date as the Offer
Conditions have been satisfied or such later date as required by applicable law;
provided,  however,  that nothing  herein shall  require Sub to extend the Offer
beyond the Outside Date; provided, further, that neither Parent nor Sub shall be
obligated to make any such extension if, in the  reasonable  belief of Parent or
Sub, as  applicable,  all Offer  Conditions  are not capable of being  satisfied
prior to the Outside Date.  Subject to the terms and conditions of the Offer and
this Agreement, Sub shall, and Parent shall cause Sub to, accept for payment and
pay for, all Shares  validly  tendered and not  withdrawn  pursuant to the Offer
that Sub is permitted to accept for payment and pay for under applicable law, as
soon as  practicable  (and, in any event,  within three  business days after the
later of the  expiration of the Offer and the receipt by the  depository for the
Offer of the certificates  representing such tendered Shares). If this Agreement
is  terminated  pursuant to Section  9.1(d),  Parent or Sub shall  terminate the
Offer.  Sub may,  at any time,  transfer  or assign to one or more  corporations
directly or indirectly  wholly-owned  by Parent the right to purchase all or any
portion of the Shares tendered  pursuant to the Offer,  but any such transfer or
assignment shall not relieve Sub of its obligations under the Offer or prejudice
the rights of  tendering  shareholders  to receive  payment  for Shares  validly
tendered and accepted for payment.


                                    A-2
<PAGE>



(b) On the date of commencement of the Offer, Parent and Sub shall file with the
SEC (i) a Tender Offer  Statement on Schedule 14D-1 (the  "Schedule  14D-1") and
(ii) a Rule 13e-3 Transaction Statement on Schedule 13E-3 (the "Schedule 13E-3")
with  respect to the Offer,  which  shall  contain  an offer to  purchase  and a
related letter of transmittal and summary advertisement (such Schedule 14D-1 and
Schedule 13E-3 and the documents  included  therein  pursuant to which the Offer
shall be made, together with any supplements or amendments  thereto,  the "Offer
Documents"),  and  Parent  and  Sub  shall  cause  the  Offer  Documents  to  be
disseminated  to holders of Shares as and to the extent  required by  applicable
federal  securities  laws.  Parent,  Sub and the Company each agrees promptly to
correct any information  provided by it for use in the Offer Documents if and to
the extent that such  information  shall have become false or  misleading in any
material  respect,  and Parent and Sub further agree to take all steps necessary
to cause the Schedule  14D-1 and the Schedule  13E-3 as so corrected to be filed
with the SEC and the other Offer Documents as so corrected to be disseminated to
holders of  Shares,  in each case as and to the extent  required  by  applicable
federal  securities  laws. The Company and its counsel shall be given reasonable
opportunity to review and comment upon the Offer Documents prior to their filing
with the SEC or  dissemination  to the  Company's  shareholders.  Parent and Sub
agree to provide the Company and its counsel any comments  Parent,  Sub or their
counsel  may  receive  from  the SEC or its  staff  with  respect  to the  Offer
Documents  promptly after the receipt of such comments and to cooperate with the
Company and its counsel in responding to such comments.

(c) Parent  shall  provide or cause to be provided to Sub on a timely  basis all
funds necessary to accept for payment,  and pay for, any Shares that are validly
tendered  and not  withdrawn  pursuant to the Offer and that Sub is permitted to
accept for payment under applicable law and pay for, pursuant to the Offer.

Section 1.2. Company Actions.

(a) The Company hereby  approves of and consents to the Offer and represents and
warrants  that the Board of Directors  of the Company,  at a meeting duly called
and held,  duly adopted (by unanimous  vote,  with the Affiliated  Directors (as
defined in the Standstill  Agreement) not participating)  resolutions  approving
the  Offer,  this  Agreement,   the  Merger  and  the  Shareholders   Agreement,
determining that the Offer and the Merger are fair to, and in the best interests
of, the Company's  shareholders and recommending that the Company's shareholders
accept  the  Offer  and  approve  and  adopt  this  Agreement  and  the  Merger.
Simultaneously  with the execution of this Agreement,  each of the  Unaffiliated
Directors of the Company has  indicated to the Company that he intends to tender
and sell his Shares in response to the Offer, except that Unaffiliated Directors
whose sales of their  Shares in response to the Offer might  result in liability
under  Section  16(b) of the  Exchange Act intend that if they do not tender and
sell their  Shares in  response  to the Offer,  they shall vote their  Shares in
favor of the  Merger.  The Company  represents  and  warrants  that its Board of
Directors has received the opinion of each of BT Alex. Brown  Incorporated  ("BT
Alex.  Brown") and Warburg Dillon Read LLC ("Warburg Dillon Read") to the effect
that, as of the date of this Agreement, the cash consideration to be received in
the Offer and the Merger by holders of Shares (other than Parent and  Affiliates
thereof) is fair to such  holders  from a financial  point of view.  The Company
hereby consents to the inclusion in the Offer  Documents of the  recommendations
of the Company's Board of Directors described in this Section 1.2.

(b) On the date the Offer  Documents  are filed with the SEC, the Company  shall
file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with
respect to the Offer (such  Schedule  14D-9,  as amended from time to time,  the
"Schedule 14D-9") containing the recommendation  described in Section 1.2(a) and
shall cause the Schedule 14D-9 to be disseminated to the Company's  shareholders
as and to the extent required by applicable federal securities laws. Each of the
Company,  Parent and Sub agrees promptly to correct any information  provided by
it for use in the  Schedule  14D-9 if and to the  extent  that such  information
shall have become false or misleading in any material  respect,  and the Company
further  agrees to take all steps  necessary to amend or supplement the Schedule
14D-9 and to cause the Schedule 14D-9 as so amended or  supplemented to be filed
with the SEC and disseminated to the Company's shareholders, in each case as and
to the extent required by applicable  federal  securities  laws.  Parent and its
counsel  shall be given  reasonable  opportunity  to review and comment upon the
Schedule  14D-9  prior  to its  filing  with  the  SEC or  dissemination  to the
Company's shareholders. The Company agrees to provide Parent and its counsel any
comments  the Company or its counsel may receive  from the SEC or its staff with
respect to the Schedule 14D-9 promptly after the receipt of such comments and to
cooperate with Parent, Sub and their counsel in responding to such comments.


                                    A-3

(c) In  connection  with the Offer and the Merger,  the Company  shall cause its
transfer agent to furnish Sub promptly with mailing labels  containing the names
and  addresses of the record  holders of Shares as of a recent date and of those
Persons becoming record holders subsequent to such date, together with copies of
all lists of shareholders, security position listings and computer files and all
other  information  in  the  Company's   possession  or  control  regarding  the
beneficial  owners of  Shares,  and shall  furnish to Sub such  information  and
assistance (including updated lists of shareholders,  security position listings
and computer files) as Parent or Sub may reasonably request in communicating the
Offer  to  the  record  and  beneficial  holders  of  Shares.   Subject  to  the
requirements  of  applicable  law, and except for such steps as are necessary to
disseminate the Offer Documents and any other documents  necessary to consummate
the Merger,  Parent and Sub and their  Affiliates,  associates  and agents shall
hold in confidence the  information  contained in any such labels,  listings and
files,  shall use such  information  only in  connection  with the Offer and the
Merger and, if this Agreement shall be terminated, shall promptly, upon request,
deliver, and shall use reasonable efforts to cause their Affiliates,  associates
and agents to deliver,  to the Company  all copies of such  information  then in
their possession or control.

Section 1.3. Standstill Agreement.  Effective upon the acquisition of Shares
pursuant to the Offer, the Standstill Agreement shall terminate in its entirety.

and in accordance  with the PBCL,  Sub shall be merged with and into the Company

the rights and obligations of Sub and the Company in accordance with the PBCL.

Section 2.2.  Effective  Time;  Closing.  As promptly as  practicable  after the
satisfaction  or, if permissible,  waiver of the conditions set forth in Article

Pennsylvania,  or at such  later  time,  which  shall  be as soon as  reasonably
practicable,  specified  as the  effective  time in the  Articles of Merger (the
"Effective Time").  Prior to such filing, a closing shall be held at the offices
of Rogers & Wells LLP, 200 Park Avenue,  New York, New York 10166,  USA, or such

satisfaction  or  waiver,  as the case may be,  of the  conditions  set forth in
Article VIII.

in Section 1929 of the PBCL.

             ARTICLE III - EFFECT OF THE MERGER ON THE STOCK OF THE
               CONSTITUENT CORPORATIONS; SURRENDER OF CERTIFICATES

Section 3.1.  Effect on Stock. As of the Effective Time, by virtue of the Merger
and without any action on the part of any of Sub,  the Company or the holders of
any securities of the  Constituent  Corporations  and in accordance with Section
1906 of the PBCL:

(a) Capital Stock of Sub. Each issued and outstanding  share of capital stock of
Sub shall be  converted  into and  become  one  validly  issued,  fully paid and
nonassessable  share  of  common  stock,  $1.00  par  value,  of  the  Surviving
Corporation.

(b)  Treasury  Stock and  Parent  Owned  Stock.  Each Share that is owned by the
Company  or by any  Subsidiary  of the  Company  and each Share that is owned by
Parent,  Sub or any other Subsidiary of Parent shall  automatically be cancelled
and retired and shall cease to exist, and no consideration shall be delivered in
exchange therefor.

(c)  Conversion  of Shares.  Subject to Section  3.1(d),  each Share  issued and
outstanding  (other than  Shares to be  cancelled  in  accordance  with  Section
3.1(b)),  shall be cancelled and be converted into the right to receive from the
Surviving  Corporation  in cash,  without  interest or dividends,  the price per
Share paid in the Offer (the "Merger Consideration").  As of the Effective Time,
all such Shares shall be cancelled,  and when so  cancelled,  shall no longer be
outstanding  and shall  automatically  be retired and shall cease to exist,  and
each holder of a  certificate  representing  any such Shares shall cease to have
any  rights  with  respect  thereto,  except  the right to  receive  the  Merger
Consideration for each such Share, without interest or dividends.

(d)  Shares  of  Dissenting  Shareholders.   Notwithstanding  anything  in  this
Agreement to the contrary, any issued and outstanding Shares held by a Person (a
"Dissenting  Shareholder")  who has not  voted in favor of or  consented  to the
Merger and complies in all respects  with Sections 1930 and 1575 through 1580 of
the PBCL concerning the right of holders of Shares to require appraisal of their
Shares  ("Dissenting  Shares")  shall not be  converted  as described in Section
3.1(c),  but shall become the right to receive payment of the fair value of such
Shares in accordance  with Sections 1930 and 1575 through 1580 of the PBCL.  If,
after the Effective Time, a holder of Dissenting Shares withdraws his demand for
appraisal or fails to perfect or otherwise loses his right of appraisal,  in any
case pursuant to the PBCL,  his Shares shall be deemed to be converted as of the
Effective Time into the right to receive the Merger  Consideration for each such
Share,  without  interest or  dividends.  The Company  shall give Parent  prompt
notice of any demands for  appraisal  of Shares  received  by the  Company.  The
Company shall not, without the prior written consent of Parent, make any payment
with respect to, or settle or offer to settle, any such demands.

Section 3.2. Surrender of Certificates.

(a) Paying Agent.  Prior to the Effective Time, Parent shall designate a bank or
trust  company  who shall be  reasonably  satisfactory  to the Company to act as
paying  agent in the Merger (the  "Paying  Agent"),  and from time to time,  on,
prior to or after the Effective Time, Parent shall make available,  or cause the
Surviving Corporation to make available, to the Paying Agent cash in the amounts
necessary for the payment of the Merger Consideration as provided in Section 3.1
upon  surrender  as part of the  Merger of  certificates  formerly  representing
Shares. Funds made available to the Paying Agent shall be invested by the Paying
Agent as directed by Parent (it being  understood  that any and all  interest or
income  earned on funds made  available  to the Paying  Agent  pursuant  to this
Agreement shall be turned over to Parent).

(b) Exchange  Procedure.  As soon as reasonably  practicable after the Effective
Time,  the  Surviving  Corporation  shall cause the Paying Agent to mail to each
holder of record of a certificate or certificates  that immediately prior to the
Effective  Time  represented  Shares  (the  "Certificates"),  (i)  a  letter  of
transmittal  (which shall specify that delivery  shall be effected,  and risk of
loss and  title to the  Certificates  shall  pass,  only  upon  delivery  of the
Certificates  to the  Paying  Agent and  shall be in a form and have such  other
provisions as Parent may reasonably  specify) and (ii)  instructions  for use in
effecting  the  surrender  of  the  Certificates  in  exchange  for  the  Merger
Consideration  as provided in Section 3.1. Upon  surrender of a Certificate  for
cancellation  to the  Paying  Agent or to such  other  agent or agents as may be
appointed by Parent,  together with such letter of  transmittal,  duly executed,
and such other documents as may reasonably be required by the Paying Agent,  the
holder of such Certificate shall be entitled to receive in exchange therefor the
amount of cash, without interest or dividends, into which the Shares theretofore
represented by such  Certificate  shall have been converted  pursuant to Section
3.1, and the  Certificate so surrendered  shall  forthwith be cancelled.  In the
event of a  transfer  of  ownership  of  Shares  that is not  registered  in the
transfer records of the Company,  payment may be made to a Person other than the
Person in whose name the  Certificate  so  surrendered  is  registered,  if such
Certificate  shall be  properly  endorsed  or  otherwise  be in proper  form for
transfer and the Person  requesting such payment shall pay any transfer or other
taxes  required by reason of the payment to a Person  other than the  registered
holder of such  Certificate  or establish to the  satisfaction  of the Surviving
Corporation that such tax has been paid or is not applicable.  Until surrendered
as contemplated by this Section 3.2, each Certificate  (other than  Certificates
representing  Dissenting Shares) shall be deemed at any time after the Effective
Time to represent  only the right to receive upon such  surrender  the amount of
cash, without interest or dividends,  into which the Shares of stock theretofore
represented by such  Certificate  shall have been converted  pursuant to Section
3.1.  No interest  shall be paid or shall  accrue on the cash  payable  upon the
surrender  of any  Certificate.  Parent or the Paying Agent shall be entitled to
deduct and withhold from the  consideration  otherwise  payable pursuant to this
Agreement  to any holder of Shares such amounts as Parent or the Paying Agent is
required to deduct and withhold with respect to the making of such payment under
the Code or under any  provision  of state,  local or  foreign  tax law.  To the
extent that amounts are so withheld by Parent or the Paying Agent, such withheld
amounts shall be treated for all purposes of this  Agreement as having been paid
to the holder of the Shares in respect of which such  deduction and  withholding
was made by the Parent or the Paying Agent.

(c) No Further  Ownership Rights in Shares.  All cash paid upon the surrender of
Certificates in accordance with the terms of this Article III shall be deemed to
have been paid in full  satisfaction  of all  rights  pertaining  to the  Shares
theretofore  represented by such Certificates.  At the Effective Time, the stock
transfer  books of the  Company  shall be closed,  and there shall be no further
registration  of  transfers  on  the  stock  transfer  books  of  the  Surviving
Corporation  of the  Shares  that  were  outstanding  immediately  prior  to the
Effective Time. If, after the Effective Time,  Certificates are presented to the
Surviving  Corporation  or the  Paying  Agent  for any  reason,  they  shall  be
cancelled and exchanged as provided in this Article III.


                                    A-6
<PAGE>



(d)  Termination of Payment Fund. Any portion of the funds made available to the
Paying Agent to pay the Merger Consideration which remains  undistributed to the
holders of Shares for six months after the Effective  Time shall be delivered to
Parent, upon demand, and any holders of Shares who have not theretofore complied
with  this  Article  III  and  the  instructions  set  forth  in the  letter  of
transmittal  mailed to such holders  after the Effective  Time shall  thereafter
look only to the Surviving  Corporation (subject to abandoned property,  escheat
or other similar laws) for payment of the Merger Consideration to which they are
entitled, without interest or dividends.

(e) No Liability.  None of Parent, Sub, the Company or the Paying Agent shall be
liable to any  Person in  respect  of any cash  delivered  to a public  official
pursuant to any applicable abandoned property, escheat or similar law.

(f) Company Options.  The Company hereby represents and warrants that either (i)
all  outstanding  options to purchase  Shares (the "Company  Options"")  granted
under the  Company's  1986 Long Term  Incentive  Stock  Plan and the 1995  Stock
Incentive Plan (the "Company Option Plans"),  whether or not then exercisable or
vested,  shall,  pursuant to the terms of the Company Option Plans, be cancelled
as of the consummation of the Offer and the holders thereof shall be entitled to
receive  from Parent upon  consummation  of the Offer,  in respect of each Share
subject to such Company Option,  an amount in cash equal to the excess,  if any,
of the Merger  Consideration  over the exercise  price per share  thereof  (such
payment to be net of  applicable  withholding  taxes) or (ii) the Company  shall
take all such  steps as shall be  necessary  to achieve  substantially  the same
result as described in clause (i) of this paragraph (f).

(g) Company Option Plans.  The Company  hereby  represents and warrants that all
Company  Option  Plans  provide,  or have  been or will be  amended  as and when
required to provide for the actions  described  in Section  3.2(f)  hereof.  The
Company  shall cause the Company  Option Plans to terminate as of the  Effective
Time.

           ARTICLE IV - REPRESENTATIONS AND WARRANTIES OF THE COMPANY

In addition to the representations and warranties of the Company in Sections 1.2
and 3.2(f) and (g) hereof, the Company  represents and warrants to Parent and
Sub as follows:

authority to carry on its business as now being conducted.  The Company and each
of its  Subsidiaries  is duly  qualified  or licensed to do business and in good
standing  in each  jurisdiction  in which  the  nature  of its  business  or the
ownership or leasing of its  properties  makes such  qualification  or licensing
necessary,  except  in  such  jurisdictions  where  the  failure  to be so  duly
qualified or licensed and in good standing  would not  reasonably be expected to
have a Materially  Adverse Effect on the Company or prevent or materially  delay
the  consummation  of the Offer and/or the Merger.  The Company has delivered to
Parent complete and correct copies of its Articles of Incorporation  and By-laws
and has made available to Parent the Articles of  Incorporation  and By-laws (or
similar organizational documents) of each of its Subsidiaries.

contractual obligations of the Company or any of its Subsidiaries to repurchase,
redeem or  otherwise  acquire any Company  Securities,  or any shares of capital
stock of any Subsidiaries of the Company.

Section 4.4.  Authorization;  Binding  Agreement.  The Company has all requisite
corporate power and authority to execute and deliver this Agreement,  to perform
its  obligations  hereunder  and to  consummate  the  transactions  contemplated
hereby.  The  execution,  delivery and  performance  of this  Agreement  and the
consummation of the transactions contemplated hereby, including, but not limited
to,  the Offer and the  Merger,  have been duly and  validly  authorized  by the
Company's Board of Directors and no other  corporate  proceedings on the part of
the Company or any of its  Subsidiaries are necessary to authorize the execution
and delivery of this  Agreement or to consummate the  transactions  contemplated
hereby  (other than the adoption of this  Agreement by the  shareholders  of the
Company to the extent  required by the PBCL).  This  Agreement has been duly and
validly  executed and delivered by the Company and constitutes the legal,  valid
and  binding  agreement  of the  Company,  enforceable  against  the  Company in

<PAGE>



Company  has  approved  this  Agreement,   the  Shareholder  Agreement  and  the
transactions  contemplated  hereby and thereby (including but not limited to the
Offer, the Merger and the matters provided for in the Shareholder  Agreement) so
as to  render  inapplicable  hereto  and  thereto  the  limitation  on  business
combinations contained in Chapter 25 of the PBCL (or any similar provision).  As
a result,  the only  vote of  holders  of any  class or series of the  Company's
capital stock required to adopt this Agreement and the transactions contemplated
hereby,  including  the  Merger,  is the  affirmative  vote of a majority of the
outstanding  Shares, and if Section  1924(b)(1)(ii) of the PBCL is applicable to
the Merger,  no such vote shall be required.  No other state takeover or control
share statute or similar  statute or regulation  applies or purports to apply to

contemplated hereby or thereby.

Section 4.5. Consents and Approvals; No Violations.  Except as set forth in Item
4.5 of the Company Letter, except for filings, permits, authorizations, consents

the Exchange  Act, the HSR Act, the PBCL,  state  takeover  laws and foreign and
supranational laws relating to antitrust and anticompetition clearances, neither
the execution,  delivery or performance of this Agreement by the Company nor the
consummation  by the  Company of the  transactions  contemplated  hereby nor the
consummation of the transactions  contemplated by the Shareholders  Agreement by
the  parties  thereto  will (i)  conflict  with or result  in any  breach of any
provision of the Articles of  Incorporation  or By-laws of the Company or of the
similar  organizational  documents of any of its Subsidiaries,  (ii) require any
filing with, or permit, authorization,  consent or approval of, any Governmental
Entity or other Person,  (iii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, amendment, cancellation or acceleration) under, any of
the material  terms,  conditions  or  provisions  of any note,  bond,  mortgage,
indenture, lease, license, contract, agreement or other instrument or obligation
to which the  Company or any of its  Subsidiaries  is a party or by which any of
them or any of their  properties  or  assets  may be bound or (iv)  violate  any
order, writ, injunction,  decree,  statute, rule or regulation applicable to the
Company, any of its Subsidiaries or any of their properties or assets.

Section 4.6. SEC Documents and Other Reports. The Company has filed with the SEC
all  documents  required  to be filed by it since  August  31,  1995  under  the
Securities  Act or the Exchange Act (the "Company SEC  Documents").  As of their
respective  filing  dates,  the Company SEC  Documents  complied in all material
respects with the requirements of the Securities Act or the Exchange Act, as the
case may be, each as in effect on the date so filed,  and at the time filed with
the SEC none of the Company SEC Documents, including the financial statements of
the Company and the notes thereto,  contained any untrue statement of a material

applicable  accounting  requirements  and the published rules and regulations of
the SEC with respect  thereto,  have been prepared in accordance  with generally
accepted accounting  principles (except in the case of the unaudited statements,
as permitted by Form 10-Q under the Exchange Act) applied on a consistent  basis
during the periods involved (except as may be indicated  therein or in the notes
thereto) and fairly present the consolidated  financial  position of the Company
and its  consolidated  Subsidiaries as at the dates thereof and the consolidated
results of their  operations and their  consolidated  cash flows for the periods
then ended  (subject,  in the case of unaudited  statements,  to normal year-end
audit adjustments and to any other  adjustments  described therein none of which
were or will be  material  in amount or  effect).  The  Company  has  heretofore
furnished  or made  available  to  Parent a  complete  and  correct  copy of any
amendments  or  modifications  which  have  not yet been  filed  with the SEC to
executed  agreements,  documents or other  instruments which previously had been
filed by the Company with the SEC pursuant to the Securities Act or the Exchange
Act. No Subsidiary is required to file any form,  report or other  document with
the SEC.

applicable  statute of limitations to assess any Taxes. There are no outstanding
requests by the Company or any of its  Subsidiaries  for any  extension  of time
within which to file any Tax Return or within which to pay any material  amounts
of Taxes shown to be due on any return. No claim has been made in writing to the
Company or to any of its Subsidiaries in the past three years by an authority in
a  jurisdiction  where the Company or its  Subsidiaries  do not file Tax Returns
that it is or may be subject to taxation by that jurisdiction,  nor is there any
meritorious  basis for an investigation or other proceeding that would result in
such an assessment. To the best knowledge of the Company, there are no liens for
Taxes  on the  assets  of the  Company  or any of its  Subsidiaries  except  for
statutory liens for current Taxes not yet due and payable.

(b) Section 4.12 of the Company  Letter sets forth (1) the taxable  years of the
Company and its Subsidiaries as to which the respective  statutes of limitations
have not expired, and (2) with respect to such years, sets forth those years for
which  examinations have been completed,  those years for which examinations are
presently  being  conducted,  those years for which  examinations  have not been
initiated, and those years for which Tax Returns have not yet been filed.

(c) All material elections with respect to Tax affecting the Company as of the
date hereof are set forth in Section  4.12(c) of the Company Letter.

(d) Neither the Company nor any of its  Subsidiaries  has filed a consent  under
Section  341(f) of the Code  concerning  collapsible  corporations.  Neither the
Company nor any of its  Subsidiaries  has made any payments,  or is obligated to
make  any  payments,  or  is  a  party  to  any  agreement  that  under  certain
circumstances could obligate it to make any payments that will not be deductible
under Sections  162(m) or 280G of the Code or any similar  provision of foreign,
state or local law.  Neither the Company nor any of its  Subsidiaries is a party
to or bound by any tax  indemnity,  tax sharing or tax  allocation  agreement or
arrangement.  Except for the group of which the Company is presently  the common
parent,  neither the Company nor any of its  Subsidiaries has ever been a member
of an affiliated  group of  corporations,  within the meaning of Section 1504 of
the Code.

(e) Neither the Company nor any of its Subsidiaries has (i) a material amount of
income reportable for a period ending after the Effective Time, but attributable
to a  transaction  (e.g.,  an  installment  sale)  occurring  in or a change  in
accounting  method made for a period  ending on or prior to the  Effective  Time
which resulted in a deferred  reporting of income from such  transaction or from
such  change  in  accounting   method   (other  than  a  deferred   intercompany
transaction);  or  (ii)  deferred  gain  or  loss  arising  out of any  deferred
intercompany  transaction.  Neither the Company nor any of its  Subsidiaries has
any excess loss account (as defined in Treasury  Regulation  Section  1.1502-19)
with  respect to the stock of any of its  Subsidiaries.  No  "ownership  change"
(within  the  meaning  of  Section  382(g) of the Code)  has,  to the  Company's
knowledge,  occurred  prior  to the  date  hereof  which  currently  limits  the
Company's ability to utilize any net operating loss carryovers under Section 382
of the Code.

(f) For  purposes  of this  Agreement,  the term "Tax"  shall mean any  federal,
state, local,  foreign or provincial income,  gross receipts,  property,  sales,
use,  license,  excise,  franchise,  employment,  payroll,  alternative or added
minimum,  ad valorem,  transfer or excise tax, or any other tax,  custom,  duty,
governmental  fee or other  like  assessment  or charge of any kind  whatsoever,
together with any interest or penalty imposed by any  Governmental  Entity.  The
term "Tax Return" shall mean a report,  return or other  information  (including
any  attached  schedules  or any  amendments  to such  report,  return  or other
information) required to be supplied to or filed with a Governmental Entity with
respect to any Tax, including an information return,  claim for refund,  amended
return or declaration or estimated Tax.

Section 4.13. Litigation and Liabilities. Except as disclosed in the Company SEC
Documents  and  except  as set  forth  in Item  4.13 of the  Company  Letter  or
otherwise  disclosed  in  writing  to  Parent,  (a)  there is no  suit,  action,
arbitration,  investigation,  claim,  proceeding or audit ("Litigation") pending
or, to the best knowledge of the Company,  threatened against the Company or any
of its Subsidiaries, nor is there any judgment, decree, writ, award, injunction,
rule or order of any Governmental  Entity outstanding against the Company or any
of  its  Subsidiaries  that  are  reasonably  likely,  individually  or  in  the
aggregate,  to have a Materially Adverse Effect; (b) there are no obligations or
liabilities,   contingent,  absolute,  determined,  determinable  or  otherwise,
including,  without limitation, those relating to environmental and occupational
safety and health matters,  that are reasonably  likely,  individually or in the
aggregate, to have a Materially Adverse Effect and (c) as of the date hereof, no
facts are known to the  executive  officers or  directors  of the Company on the
date hereof that could reasonably be expected to form the basis for valid claims
as to which  rights  to  indemnification  and  advancement  of  expenses  to the
executive  officers  or  directors  of the  Company or any  Subsidiary  would be
applicable.

Section 4.14. Employee Benefit Plans.

(a) As used in this  Agreement,  "Benefit Plan" shall mean any employee  benefit
plan, including, without limitation, (i) any employee benefit plan as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended,
together with all regulations  thereunder ("ERISA") maintained or contributed to
by the Company or any Subsidiary during the three-year period preceding the date
hereof, whether or not such plan is subject to any or all of ERISA's provisions,
and (ii) whether or not described in the preceding clause,  any pension,  profit
sharing, severance, employment, change-in-control,  bonus, stock bonus, deferred
or supplemental  compensation,  retiree medical or life insurance, death benefit
or insurance,  retirement,  thrift,  stock  purchase or stock option plan or any
other compensation,  welfare, fringe benefit,  perquisite or retirement plan, or
other material program,  policy or arrangement of any kind or nature whatsoever,
whether oral or written,  maintained or  contributed to by the Company or any of
the Subsidiaries or otherwise  providing for  compensation,  benefits for or the
welfare of any or all of the current or former employees, directors, consultants
or agents of the Company or any of its  Subsidiaries or their  beneficiaries  or
dependents.  Except as set forth in Item 4.14 of the Company Letter, neither the
Company nor any of its Subsidiaries contributes to or has at any time during the
six-year period preceding the date of this Agreement  contributed to, or has any
outstanding  liability  with  respect to, any  Multiemployer  Plan as defined in
Section 3(37) of ERISA.

(b) Except as set forth in Item 4.14 of the  Company  Letter and except for such
instances  of  non-compliance   with  ERISA  and  the  regulations   promulgated
thereunder that, individually or in the aggregate, have not had and would not be
reasonably  likely in the  future  to have a  Materially  Adverse  Effect on the
Company:  (i) each  Benefit  Plan  has  been  established  and  administered  in
accordance with its terms and in compliance with applicable provisions of ERISA,
the Code and all other applicable laws, rules and regulations;  (ii) the Company
has received no notice from any Governmental  Entity  questioning or challenging
such  compliance;  (iii) each Benefit Plan which is intended to be tax-qualified
under Code Sections  401(a) and (k) (as  applicable) is so qualified in form and
operation  and  has  received  a  favorable   determination  letter  as  to  its
qualification,  and nothing has  occurred,  whether by action or failure to act,
that would cause the loss of such qualification;  (iv) no event has occurred and
no condition exists with respect to a Benefit Plan or other plan (whether or not
covering employees of the Company or any of its Subsidiaries) that would subject
the Company or any of its  Subsidiaries,  either  directly or by reason of their
affiliation  with an ERISA  Affiliate (as  hereinafter  defined) to any material
tax, fine, lien or penalty imposed by ERISA,  the Code or other applicable laws,
rules and  regulations;  (v) for each  Benefit Plan with respect to which a Form
5500 has been filed, no material change has occurred with respect to the matters
covered by the most recent Form 5500 since the date thereof; (vi) no "reportable
event" (as such term is defined in ERISA Section 4043) other than any event with
respect to which  reporting is waived  pursuant to the  regulations  under ERISA
Section  4043,  "prohibited  transactions"  (as such  term is  defined  in ERISA
Section 406 and Code Section 4975),  "accumulated  funding  deficiency" (as such
term is  defined in ERISA  Section  302 and Code  Section  412  (whether  or not
waived))  or failure to make by its due date a required  installment  under Code
Section  412(m) has occurred with respect to any Benefit Plan, or any other plan
maintained  for  employees  of any ERISA  Affiliate of the Company or any of its
Subsidiaries.  "ERISA  Affiliate,"  as  applied  to any  Person,  means  (i) any
corporation which is a member of a controlled group of corporations  (within the

or businesses  under common control  (within the meaning of Code Section 414(c))
of which that Person is a member and (iii) any member of an  affiliated  service
group (within the meaning of Code Section  414(m) and (o)) of which that Person,
any corporation described in clause (i) above or any trade or business described
in clause (ii) above is a member.

(c) With respect to any Benefit  Plan,  (i) no actions,  suits or claims  (other
than routine claims for benefits in the ordinary  course) are pending or, to the
knowledge of the Company,  threatened and (ii) no facts or circumstances  exist,
to the knowledge of the Company,  that could reasonably be expected to give rise
to any such actions, suits or claims.

(d) Except as set forth in Item 4.14 of the  Company  Letter,  no  Benefit  Plan
exists  that  could  result in the  payment to any  present or former  employee,
director,  consultant or agent of the Company or any of its  Subsidiaries of any
money or other property,  or accelerate or provide any other rights or benefits,
to any  such  Person  as a  result  of the  transactions  contemplated  by  this
Agreement,  whether or not such payment  would  constitute  a parachute  payment
within the meaning of Code Section 280G,  and no payment in respect of a Benefit
Plan would constitute an excess parachute payment under Code Section 280G.

Directors or such  committee of the Offer,  the Merger or this Agreement (or any
transaction  contemplated  thereby);  provided that, the Unaffiliated  Directors
may, (A) in response to any Takeover Proposal, suspend such recommendation for a
period of up to 24 hours pending the analysis by the  Unaffiliated  Directors of
such  Takeover  Proposal,  which  analysis  may include to the extent  necessary
discussions with a Person making such Takeover  Proposal  regarding same, or (B)
at any time prior to the  consummation  of the Offer,  modify or  withdraw  such

such recommendation,  (ii) approve or recommend,  or propose publicly to approve

Directors  shall  take all  actions  legally  permitted  to permit the Merger to
occur.

Section 6.3.  Disclosure  to Parent;  Delivery of Certain  Filings.  The Company
shall  promptly  advise  Parent  orally and in writing if there  occurs,  to the
knowledge of the  Company,  any change or event which  results in the  executive
officers of the Company having a good faith belief that such change or event has
resulted in or is reasonably likely to result in a Materially  Adverse Effect on
the Company or that such change or event could materially delay the consummation
of the Offer and/or the Merger.  The Company shall provide to Parent, and Parent

                       ARTICLE VII - ADDITIONAL AGREEMENTS

Section 7.1. Shareholder Approval; Preparation of Proxy Statement.

(a) If the approval of the  Company's  shareholders  of this  Agreement  and the
Merger is required by law, the Company shall,  at Parent's  request,  as soon as
practicable  following the expiration of the Offer in accordance  with the terms
of Section 1.1 of this  Agreement,  so long as permitted by law, duly call, give
notice of,  convene and hold a meeting of its  shareholders  (the  "Shareholders
Meeting") for the purpose of obtaining such approval. The Company shall, through
its Board of  Directors  (but  subject  to the right of the  Company's  Board of
Directors to withdraw or modify its approval or recommendation of the Offer, the
Merger and this  Agreement  as set forth in Section  6.2(b)),  recommend  to its
shareholders  that the  shareholders  approve  the Merger.  Notwithstanding  the
foregoing, if Sub or any other Subsidiary of Parent shall acquire 80% or more of
the then outstanding  Shares, the parties shall, at the request of Parent,  take
all necessary and appropriate actions to cause the Merger, pursuant to the terms
thereof,  to become effective in accordance with Section  1924(b)(1)(ii)  of the
PBCL, as promptly as practicable after such acquisition without a meeting of the
Shareholders  of the Company,  including,  without  limitation,  adoption by the
board of directors of Sub of a short-form  plan of merger in accordance with the
PBCL and consistent with the terms of the Merger.

(b) If the approval of the  Company's  shareholders  of this  Agreement  and the
Merger is required by law, the Company shall,  at Parent's  request,  as soon as
practicable  following the expiration of the Offer in accordance  with the terms
of  Section  1.1,  and to the  extent  permitted  by  law,  prepare  and  file a
preliminary Proxy Statement with the SEC and shall use all reasonable efforts to
respond to any comments of the SEC or its staff, and, to the extent permitted by
law, to cause the Proxy Statement to be mailed to the Company's  shareholders as
promptly  as  practicable   after   responding  to  all  such  comments  to  the
satisfaction  of the staff.  The Company  shall  notify  Parent  promptly of the
receipt of any comments  from the SEC or its staff and of any request by the SEC
or its  staff for  amendments  or  supplements  to the  Proxy  Statement  or for
additional information and shall supply Parent with copies of all correspondence
between the Company or any of its representatives,  on the one hand, and the SEC
or its staff,  on the other hand,  with  respect to the Proxy  Statement  or the
Merger.  If at any time prior to the Shareholders  Meeting there shall occur any
event  that  should  be set forth in an  amendment  or  supplement  to the Proxy
Statement,  the Company shall promptly prepare and mail to its shareholders such
an  amendment or  supplement.  Parent  shall  cooperate  with the Company in the
preparation  of the Proxy  Statement  or any  amendment or  supplement  thereto.
Parent and its counsel  shall be given a  reasonable  opportunity  to review and
comment upon the Proxy Statement and any such correspondence prior to its filing
with the SEC or  dissemination  to the Company's  shareholders,  and the Company
shall  not so file or  disseminate  any Proxy  Statement,  or any  amendment  or
supplement thereto, to which Parent reasonably objects.

(c) Parent  agrees to cause all Shares  purchased  pursuant to the Offer and all
other  Shares of the Company  entitled to vote on the Merger  owned by Parent or
any Subsidiary of Parent to be voted in favor of the Merger.

Section 7.2. Access to  Information.  Between the date of this Agreement and the
Effective  Time,  the Company shall give,  and shall cause its  accountants  and
legal  counsel to give,  Parent and its  respective  authorized  representatives
(including,  without limitation,  its financial advisors,  accountants and legal
counsel),  at all  reasonable  times,  access  as  reasonably  requested  to all
personnel,  offices  and  other  facilities  and to all  contracts,  agreements,
commitments,  books  and  records  of or  pertaining  to  the  Company  and  its
Subsidiaries,  shall  permit  the  foregoing  Persons  to make  such  reasonable
inspections  as they may require  and, as  permitted  under  applicable  law and
subject to certain  restrictions  existing as of the date of this Agreement that
are known to all parties  hereto,  shall cause its officers  promptly to furnish
Parent with (a) such  financial and operating  data and other  information  with
respect to the business and  properties of the Company and its  Subsidiaries  as
Parent may from time to time reasonably request,  and (b) a copy of each report,
schedule  and other  document  filed or  received  by the  Company or any of its
Subsidiaries  pursuant to the requirements of applicable  securities laws or the
NASD.

each other  before  issuing  any press  release or  otherwise  making any public

to such  consultation,  except as may be required by applicable  law,  fiduciary
duties or by obligations pursuant to any listing agreement with or regulation of

Section  7.5.  State  Takeover  Laws.  If any  "fair  price" or  "control  share
acquisition"  statute  or other  similar  statute  or  regulation  shall  become
applicable to the transactions  contemplated hereby,  Parent and the Company and
their respective  Boards of Directors shall use all reasonable  efforts to grant
or obtain such  approvals  and take such  actions as are  necessary  so that the
transactions  contemplated  hereby may be consummated as promptly as practicable
on the terms  contemplated  hereby and  otherwise act to minimize the effects of
any such statute or regulation on the transactions  contemplated hereby.

Section 7.6. Indemnification, Exculpation and Insurance.

omissions  occurring at or prior to the Effective  Time existing in favor of the
current or former directors, officers or employees of the Company as provided in
the  Company's  Articles of  Incorporation  or By-laws or pursuant to agreements
existing  on the  date of this  Agreement  shall  be  assumed  by the  Surviving
Corporation,  and Parent  shall cause the  Surviving  Corporation  to honor such
obligations in accordance with the terms thereof,  without further action, as of
the Effective  Time,  and such rights shall continue in full force and effort in
accordance  with  their  respective  terms.  Such  rights,   and  the  Surviving
Corporation's and Parent's related  obligations,  shall apply in all respects to
the  current  or  former  directors,  officers  and  employees  of  each  of its
Subsidiaries as though such  directors,  officers and employees were entitled to
indemnification  rights pursuant to the Company's  Articles of  Incorporation or
By-laws as in effect on the date hereof or pursuant to such  agreements,  as the
case may be. In  addition,  from and after the  Effective  Time,  directors  and
officers  of the Company  who become or remain  directors  or officers of Parent
shall be entitled to the same indemnity rights and protections  (including those
provided by  directors'  and officers'  liability  insurance) as are afforded to
other  directors  and officers of Parent.  Notwithstanding  any other  provision
hereof, the provisions of this Section 7.6(a) are intended to be for the benefit
of, and shall be enforceable by, each  indemnified  party,  his or her heirs and
his or her  representatives and (ii) are in addition to, and not in substitution
for, any other rights to  indemnification  or contribution  that any such person
may have by contract or otherwise.

(b)  Parent  shall,  and shall  cause the  Surviving  Corporation  or one of its
Affiliates  to,  maintain  in effect  for six years  after  the  Effective  Time
policies of  directors'  and  officers'  liability  insurance  equivalent in all
material  respects  to those  maintained  by or on behalf of the Company and its
Subsidiaries  on the date hereof (and having  coverage and containing  terms and
conditions  which in the  aggregate  are not less  advantageous  to the  persons
currently  covered by such policies as insured)  with respect to claims  arising
from any actual or alleged wrongful act or omission occurring at or prior to the
Effective  Time for which a claim  has not been made  against  any  director  or
officer of the Company or any director or officer of its  Subsidiaries  prior to
the Effective Time.

occurrence, or non-occurrence,  in each case, to the knowledge of the Company or
Parent, as the case may be, of any event the occurrence,  or non-occurrence,  of
which  results in the executive  officers of the Company or Parent,  as the case
may be, having a good faith belief that such change or event would be reasonably

inaccurate in any material respect,  (y) any  representation or warranty of such
entity  contained in this  Agreement  that is qualified as to  materiality to be

Parent,  as the case may be, believing in good faith that the Company or Parent,
as the case may be, has, to the knowledge of the Company or Parent,  as the case
may be,  failed  to comply  with in all  material  respects  or  satisfy  in all
material  respects  any  covenant,  condition  or agreement of such entity to be
complied with or satisfied by it hereunder; provided, however, that the delivery
of any notice  pursuant to this Section 7.7 shall not limit or otherwise  affect
the remedies available hereunder to the party receiving such notice. Each of the
Company,  Parent and Sub shall give prompt notice to the other parties hereof of
any notice or other communication from any third party alleging that the consent
of such third party is or may be required in  connection  with the  transactions
contemplated by this Agreement.

Section  7.8.  Board of  Directors.  Promptly  after such time as Sub  purchases
Shares  pursuant to the Offer (but  subject to the  satisfaction  of the Minimum
Condition),  Sub shall be entitled,  to the fullest extent  permitted by law, to

below three for any reason  whatsoever,  the  remaining  Unaffiliated  Directors
shall, to the fullest extent  permitted by law,  designate a person to fill such
vacancy who shall be deemed to be an Unaffiliated  Director for purposes of this
Agreement or, if no  Unaffiliated  Directors  then remain,  the other  directors
shall  designate  three persons to fill such vacancies who shall not be officers
or  Affiliates  of  the  Company  or any of its  Subsidiaries,  or  officers  or
Affiliates of Parent, of any of its Subsidiaries or of any other entity in which
Parent owns,  directly or  indirectly,  any material  amount of capital stock or
other  significant  ownership  interest,  and such persons shall be deemed to be
Unaffiliated Directors for purposes of this Agreement.

Section 7.8 and prior to the Effective  Time,  any  termination  or amendment of
this Agreement by the Company,  any extension by the Company of the time for the
performance  of any  of the  obligations  or  other  acts  of Sub or  waiver  or

action by the Board of Directors  of the Company with respect to this  Agreement
(other than recommending or reconfirming the recommendation  that the holders of
the  Shares  approve  and  adopt  this  Agreement  and the  Merger,  and  making

may be made by a majority of the Board of Directors as  constituted  at any time
after such election or appointment of Sub's designees  pursuant to this Section)
shall to the fullest extent  permitted by applicable law require the concurrence
of a majority of the Unaffiliated Directors and, to the fullest extent permitted
by law,  no other  action  by the  Company,  including  any  action by any other
director  of the  Company,  shall be required to approve  such  actions.  To the
fullest extent  permitted by applicable  law, the Company shall take all actions
requested by Parent which are reasonably necessary to effect the election of any
such designee,  including mailing to its shareholders the Information  Statement
containing  the  information  required by Section  14(f) of the Exchange Act and
Rule 14f-1 promulgated  thereunder,  and the Company agrees to make such mailing
with the mailing of the Schedule 14D-9 (provided that Sub shall have provided to
the  Company on a timely  basis all  information  required to be included in the
Information Statement with respect to Sub's designees).  Parent and Sub shall be
solely  responsible for any information with respect to either of them and their
nominees,  officers,  directors and Affiliates  required by Section 14(f) of the
Exchange  Act and Rule 14f-1  promulgated  thereunder.  In  connection  with the
foregoing,  the Company shall promptly,  at the option of Parent, to the fullest
extent  permitted by law,  either  increase the size of the  Company's  Board of
Directors and/or obtain the resignation of such number of its current  directors
as is  necessary  to enable  Sub's  designees  to be elected or appointed to the
Company's Board of Directors as provided above.

(b) Shareholder  Approval.  If required by any applicable law or the constituent
documents of any party  hereto,  this  Agreement  and the Merger shall have been
approved  at or  prior  to the  Effective  Time  by the  requisite  vote  of the

be solely the affirmative vote of a majority of the outstanding Shares.

condition  (which may be waived in whole or in part by Parent)  that the Company
shall have  performed in all material  respects all  obligations  required to be

Company's Board of Directors  pursuant to Section 2.4 of this Agreement and (ii)
the Effective Time; provided, however, that no failure by the Company to have so

9.1(b)(i)  shall not be available  to any party whose  failure to perform any of
its  obligations  under this Agreement  results in the failure of any such Offer
Condition  or  if  the  failure  of  such   condition   results  from  facts  or
circumstances  that constitute a breach of any  representation or warranty under
this Agreement by such party; or

 (ii) if any Governmental Entity shall have issued an order, decree or ruling or
taken  any  other  action  permanently   enjoining,   restraining  or  otherwise

decree, ruling, or other action;

(c) by either  Parent or Sub if the Company  shall have breached in any material
respect any of its  material  covenants  or other  agreements  contained in this

Expiration Date;

(d) by any of  Company,  Parent or Sub if either  Parent or Sub is  entitled  to

accordance  with Section  6.2(b)  shall not give rise to a right of  termination
pursuant to this Section 9.1(d);

(e) by the Company if Parent or Sub shall have breached in any material  respect
any of its material  covenants or other agreements  contained in this Agreement,
which breach or failure to perform is incapable of being cured or, Parent having

effect  with no  liability  on the part of any  party  hereto  (or of any of its
directors,  officers,  employees,  agents,  legal or financial advisors or other

party  hereto  from any  liability  for any  breach of this  Agreement  prior to
termination.  If this  Agreement is  terminated as provided  herein,  each party
shall hold in confidence  all materials  obtained from, or based on or otherwise
reflecting or generated in whole or in part from information  obtained from, any
other party hereto in  connection  with the  transactions  contemplated  by this
Agreement,  and shall not use any such  materials  for the purpose of  competing
with the  businesses of the other parties  hereto,  whether  obtained  before or
after the execution hereof.

(b) In the event that this Agreement is terminated by Parent pursuant to Section
9.1(d)  hereof,  then the Company shall promptly pay Parent upon its request all
reasonable  out-of-pocket  charges  and  expenses  incurred  by  Parent  or  its
Affiliates in connection with this Agreement and the  transactions  contemplated
hereby,  including without limitation  reasonable and documented  attorneys' and

Section 9.3. Amendment. This Agreement may be amended by action taken by Parent,
Sub and  the  Company  at any  time  before  or  after  approval  hereof  by the
shareholders  of the Company (if required),  but,  after any such  approval,  no
amendment shall be made which in any way materially adversely affects the rights
of such shareholders, without the further approval of such shareholders. Without
the prior approval of a majority of the then serving Unaffiliated  Directors, if
any are then serving on the Board, this Agreement may not be amended at any time
(a)  subsequent  to the purchase by Sub of any Shares  pursuant to the Offer and

instrument in writing signed on behalf of each of the parties hereto.

may (a) extend the time for the  performance of any of the  obligations or other
acts  of  the  other  parties  hereto,   (b)  waive  any   inaccuracies  in  the
representations  and warranties  contained  herein or in any document  delivered
pursuant  thereto  and  (c)  subject  to the  terms  of  this  Agreement,  waive
compliance  with any of the  agreements  or  conditions  contained  herein.  Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in a written  instrument  signed on behalf of such party
and,  after the  purchase  of Shares  pursuant  to the  Offer,  but prior to the
Effective Time, as to the Company, only if such waiver is approved by a majority
of the then  serving  Unaffiliated  Directors,  if any are then  serving  on the
Board.

EXHIBIT B: FORM OF SHAREHOLDER AGREEMENT.

                              SHAREHOLDER AGREEMENT

This Shareholder Agreement, dated as of June 8, 1999 (this "Agreement"), is made
and entered into among EM Laboratories,  a New York corporation  ("Parent"),  EM
Subsidiary,  Inc., a Pennsylvania  corporation and a wholly owned  subsidiary of
Parent  ("Sub"),  and each of the parties  listed on the signature  pages hereto
(each a "Shareholder," and collectively, the "Shareholders").

WHEREAS,  each of the  Shareholders  is, as of the date hereof,  the  beneficial
owner of the number of shares of common  stock,  par value  $1.00 per share (the
"Common  Stock"),  of  VWR  Scientific  Products  Corporation,   a  Pennsylvania
corporation (the "Company"), set forth opposite his name on Annex I hereto;

WHEREAS, concurrently herewith, Parent, Sub and the Company have entered into an
Agreement  and  Plan  of  Merger,  dated  as of the  date  hereof  (the  "Merger
Agreement"),  which  provides,  upon the terms and subject to the conditions set
forth therein,  for (i) the  commencement by Sub of a tender offer (the "Offer")
for all of the issued and outstanding  shares of Common Stock of the Company and
(ii) the subsequent merger of Sub with and into the Company (the "Merger");

WHEREAS,  as a condition to the  willingness of Parent and Sub to enter into the
Merger  Agreement and in order to induce Parent and Sub to enter into the Merger
Agreement, Shareholders have agreed to enter into this Agreement; and

WHEREAS,  capitalized  terms  used but not  defined in this  Agreement  have the
meaning given to those terms in the Merger Agreement.

NOW, THEREFORE, in consideration of the execution and delivery by Parent and Sub
of the Merger Agreement and the mutual  representations,  warranties,  covenants
and  agreements  set forth  herein  and  therein,  and other  good and  valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, and
intending to be bound hereby, the parties hereto agree as follows:

                                   ARTICLE I.
                                TENDER OF SHARES

Section 1.1. Tender. Each Shareholder hereby agrees validly to tender his Shares
(or cause  the  record  owner of such  Shares  validly  to  tender),  and not to
withdraw any Shares so tendered,  promptly,  and in any event not later than the
fifth  business day after  commencement  of the Offer pursuant to Section 1.1 of
the Merger  Agreement and Rule 14d-2 under the Securities  Exchange Act of 1934,
as amended (the "Exchange Act");  provided,  however, that in the event that the
Unaffiliated  Directors (as defined in the Merger  Agreement)  (or any committee
designated  thereby)  shall  withdraw,  or propose  publicly  to  withdraw,  the
approval or recommendation  by such Unaffiliated  Directors or such committee of
the  Offer,  the Merger or Merger  Agreement  (or any  transaction  contemplated
thereby),  each  Shareholder  shall  have the right to  withdraw  any  Shares so
tendered. Sub hereby agrees to purchase all the Shareholder's Shares so tendered
at the  Purchase  Price  or any  higher  price  that  may be paid in the  Offer;
provided,  however,  that Sub's obligation to accept for payment and pay for the
Common Stock (including the Shares) in the Offer is subject to all the terms and
conditions of the Offer set forth in the Merger Agreement.

Section 1.2.  Certain  Warranties.  Without limiting the generality or effect of
any  other  term  or  condition  of the  Offer,  the  transfer  by  each  of the
Shareholders of his Shares to Sub in the Offer shall pass to and unconditionally
vest in Sub good and valid  title to the  Shares,  free and clear of all  liens,
claims, restrictions,  security interests, pledges, limitations and Encumbrances
(as defined herein) whatsoever.

Section 1.3.  Disclosure.  Each Shareholder  hereby authorizes Parent and Sub to
publish and disclose in the Offer  Documents  and, if approval of the  Company's
shareholders is required under  applicable  law, the Proxy Statement  (including
all documents and schedules  filed with the SEC),  his identity and ownership of
the Shares and the nature of his commitments,  arrangements  and  understandings
under  this  Agreement  provided  that  each  Shareholder  is  provided  with  a
reasonable opportunity to review in advance any such disclosure contained in the
Offer Documents or the Proxy Statement.

                                   ARTICLE II.
                                 GRANT OF PROXY

Section 2.1. Proxy. Each Shareholder hereby irrevocably  appoints Parent and Sub
(and any nominee of either  Parent or Sub) and each of them,  with full power of
substitution  and  re-substitution,  (i) as proxies for such Shareholder to vote
all of his Shares for and in the name,  place,  and stead of such Shareholder at
any meeting of the holders of Common Stock or any  adjournments or postponements
thereof or  pursuant  to any consent in lieu of a meeting,  or  otherwise,  with
respect only to the approval of this Agreement, the Merger Agreement, the Offer,
the transactions contemplated by the Merger Agreement, any matters related to or
in connection  with the Merger and any corporate  action,  the  consummation  of
which  would   violate,   frustrate  the  purposes  of,  prevent  or  delay  the
consummation  of  the   transactions   contemplated  by  the  Merger   Agreement
(including,   without  limitation,   any  proposal  to  amend  the  Articles  of
Incorporation  or By-laws of the Company or approve  any merger,  consolidation,
sale or  purchase of any assets,  issuance of Common  Stock or any other  equity
security of the Company (or a security  convertible  into an equity  security of
the Company), reorganization, recapitalization, liquidation, winding up of or by
the  Company  or any  similar  transaction)  and  (ii) as his  true  and  lawful
attorneys-in-fact to execute one or more consents or other instruments from time
to time in order to take such actions  informally without notice of a meeting of
the shareholders of the Company;  provided,  however, that in the event that the
Unaffiliated  Directors (as defined in the Merger  Agreement)  (or any committee
designated  thereby)  shall  withdraw,  or propose  publicly  to  withdraw,  the
approval or recommendation  by such Unaffiliated  Directors or such committee of
the  Offer,  the Merger or Merger  Agreement  (or any  transaction  contemplated
thereby), such appointment of Parent and Sub as proxies shall become immediately
revocable.    Each   Shareholder   agrees   that   the   foregoing   proxy   and
power-of-attorney  granted to Parent and Sub (and their respective  nominees) in
this subsection shall be irrevocable during the term of this Agreement and shall
be deemed to be coupled with an interest.  Each Shareholder  represents that any
proxies heretofore given in respect of his Shares are not irrevocable,  and that
such proxies are hereby revoked.

                                  ARTICLE III.
                                     OPTION

Section 3.1. Grant of Option.  Each Shareholder  hereby grants to Parent or Sub,
as Parent may  designate  (each,  an  "Optionee"),  an  irrevocable  option (the
"Option")  to  purchase  the  number of shares of  Common  Stock  opposite  such
Shareholder's  name on Annex I hereto and any additional  shares of Common Stock
acquired by such  Shareholder  in any capacity  (whether by exercise of options,
warrants or rights,  the conversion or exchange of  convertible or  exchangeable
securities  or by means of a  purchase,  distribution,  dividend  or  otherwise)
(collectively,  the  "Shares")  at a purchase  price of $37.00 per share or such
higher  price  as may be  paid by  Parent  or Sub  pursuant  to the  Offer  (the
"Purchase Price").

Section 3.2. Exercise of Option.

(a) Parent or Sub may  exercise,  but shall not be  required  to  exercise,  the
Option  from  time to time,  in whole  or in part,  on or after  the date of the
consummation  of the  Offer  but  prior to the  Effective  Date if the  Offer is
consummated but (whether due to improper tender or withdrawal of tender) Sub has
not accepted for payment and paid for all of a Shareholder's Shares.


                                    B-2
<PAGE>



(b) Parent and Sub's  obligation to purchase  Shares upon exercise of the Option
shall be subject to the conditions that:

(i) no preliminary or permanent injunction or other order issued by any court or
governmental,  administrative or regulatory agency or authority  prohibiting the
exercise  of the Option  pursuant to this  Agreement  shall be in effect (and no
action or proceeding  shall have been commenced or threatened for the purpose of
obtaining such an injunction or order);

(ii)  any  applicable  waiting  period  under  the  Hart-Scott-Rodino  Antitrust
Improvements  Act of 1976,  as amended  (the "HSR Act") or similar  foreign  law
required for the purchase of the Shares upon such  exercise  shall have expired;
and

(iii)  there  shall  have  been  no  material  breach  of  the  representations,
warranties  or  covenants  of  any  Shareholder  contained  in  this  Agreement;
provided,  that any failure by Parent or Sub to purchase Shares upon exercise of
the Option at any Closing (as defined below) as a result of the  nonsatisfaction
of any of such conditions shall not affect or prejudice Parent or Sub's right to
purchase such Shares upon the subsequent satisfaction of such conditions.

(c) In the event that Parent or Sub, as the case may be,  wishes to exercise the
Option,  Parent or Sub, as the case may be,  shall send a written  notice to the
Shareholders  specifying the total number of such Shareholder's Shares it wishes
to purchase  and the place and date for the closing of such  purchase  (each,  a
"Closing") at least three business days prior to such Closing; and

(d) At any  Closing,  (i) each  Shareholder  shall  deliver to Parent or Sub (in
accordance with Parent or Sub's instructions) a certificate or certificates (the
"Certificates") representing all of such Shareholder's Shares being purchased by
Sub at the Closing,  duly endorsed or  accompanied by stock powers duly executed
in blank and (ii) Sub shall  deliver to such  Shareholder  a  certified  or bank
cashier's check or checks payable to or upon the order of such Shareholder in an
amount equal to (A) the number of such  Shareholder's  Shares being purchased at
the Closing multiplied by (B) the Purchase Price.

                                   ARTICLE IV.
                  REPRESENTATIONS AND WARRANTIES OF SHAREHOLDER

Each Shareholder severally,  and not jointly,  represents and warrants to Parent
and Sub as follows:

Section 4.1. Title to Shares.  Such  Shareholder is the sole beneficial owner of
the Shares (as may be adjusted from time to time pursuant to Section 7.1 hereof)

voting restriction, voting trust or agreement, understanding, arrangement, right
of first refusal,  limitation on disposition,  adverse claim of ownership or use
or encumbrance of any kind ("Encumbrances"),  other than restrictions imposed by
applicable  securities  laws or  pursuant  to  this  Agreement  and  the  Merger
Agreement  and  except  that as of the date  hereof  40,000  Shares  owned by N.
Stewart Rogers are pledged as security for a loan.

Section  4.2.  Total  Shares.  On the date  hereof,  the  Shares  opposite  such

exercise  the voting or  disposition  of) such  Shares and  Shareholder  owns no
options  to  purchase  or rights  to  subscribe  for or  otherwise  acquire  any

execute  and  deliver  this  Agreement  and  to  consummate   the   transactions
contemplated  hereby.  This Agreement has been duly executed and delivered by or
on behalf of such Shareholder and, assuming its due authorization, execution and
delivery by Parent and Sub, constitutes a legal, valid and binding obligation of
such  Shareholder,  enforceable  against such Shareholder in accordance with its
terms,  except  as  enforcement  may  be  limited  by  bankruptcy,   insolvency,
moratorium or other laws effecting  creditors'  rights  generally and by general
equitable principles (regardless of whether such enforceability is considered in

(a) The execution and delivery of this Agreement by such Shareholder do not, and
the performance by such Shareholder of such Shareholder's obligations under this

Shareholder or by which such Shareholder or any of such Shareholder's properties
is bound or affected or (ii) result in any breach of or constitute a default (or
an event  that with  notice  or lapse of time or both  would  become a  default)
under, or give to others any rights of termination, acceleration or cancellation
of, or result in the  creation  of a lien or  encumbrance  on any assets of such

the Exchange Act), domestic or foreign,  except where the failure to obtain such
consents,  approvals,  authorizations  or  permits,  or to make such  filings or
notifications, would not prevent or delay the performance by such Shareholder of
such Shareholder's obligations under this Agreement.  There is no beneficiary or
holder of a voting  trust  certificate  or other  interest of any trust of which
such  Shareholder  is trustee  whose  consent is required for the  execution and
delivery  of  this  Agreement  or  the   consummation   by  Shareholder  of  the
transactions contemplated hereby.

Section 4.5. No Finder's Fees. No broker,  investment banker,  financial adviser

negotiations of such  Shareholder and his agents or other  representatives  with
any person  conducted  heretofore  with  respect to any of the  foregoing.  Such
Shareholder  shall notify Parent and Sub promptly if any such proposal or offer,

the Board of Directors of the Company,  such member of the Board of Directors of
the Company may take actions in such capacity to the extent permitted by Section
6.2 of the Merger  Agreement.  As used in this  Agreement,  with  respect to any

controlled by, or under common control with, such person.

structure of the Company  affecting the Shares or the  acquisition of additional
shares of  capital  stock or other  securities  or rights of the  Company by any

Agreement  shall survive the  termination of this Agreement until the earlier to
occur of the  Closing of the  exercise of the Option and the  expiration  of the
Option.  No such  termination of this  Agreement  shall relieve any party hereto
from any liability for any breach of this Agreement prior to termination.

transactions  contemplated by this Agreement shall be for the account of the
party incurring such costs and expenses.

Section 7.7. Assignment. Neither this Agreement nor any of the rights, interests
or obligations hereunder shall be assigned by any of the parties hereto (whether
by operation of law or otherwise) without the prior written consent of the other
parties,  and any such purported  assignment  shall be null and void;  provided,
however,  that either of Parent or Sub may, without the prior written consent of

indirect  wholly owned  subsidiaries.  Subject to the preceding  sentence,  this
Agreement shall be binding upon,  inure to the benefit of and be enforceable by,

this Agreement are not intended to confer upon any person other than the parties

this Agreement  without the agreement of any other party hereto,  and thereafter
such added  shareholder  shall be treated as a "Shareholder" for all purposes of
this Agreement.

Section 7.9. Further Assurances.  Each Shareholder shall, upon request of Parent
or Sub,  execute and  deliver any  additional  documents  and take such  further
actions as may reasonably be deemed by Parent or Sub to be reasonably  necessary
or desirable to consummate,  in the most  expeditious  manner  practicable,  the
transactions contemplated by this Agreement.

Section 7.10. No Waiver.  The failure of any party hereto to exercise any right,
power, or remedy provided under this agreement or otherwise available in respect
hereof at law or in equity,  or to insist  upon  compliance  by any other  party
hereto  with his or its  obligations  hereunder,  any custom or  practice of the
parties at variance with the terms hereof shall not  constitute a waiver by such
party of his or its right to exercise any such or other  right,  power or remedy
or to demand such compliance.

party would be irreparably and immediately harmed and could not be made whole by
monetary  damages.  It is  accordingly  agreed that the parties hereto (i) shall
waive,  in any action for  specific  performance,  the  defense of adequacy of a
remedy at law and (ii) shall be  entitled,  in addition  to any other  remedy to
which they may be entitled at law or in equity,  to compel specific  performance
of this Agreement.
