            On August 11, 1998, Crane Co., a Delaware corporation ("Crane"), LTI
Merger, Inc., a Pennsylvania  corporation and a wholly owned subsidiary of Crane
("Purchaser") and Liberty  Technologies,  Inc., a Pennsylvania  corporation (the
"Issuer") entered into an Agreement and Plan of Merger (the "Merger  Agreement")
pursuant  to which,  following  consummation  of the Offer (as  defined  below),
Purchaser will be merged with and into the Issuer with the Issuer  continuing as
a wholly owned  subsidiary  of Crane.  In  connection  with the execution of the
Merger Agreement,  Parent entered into (i) a Stock Option Agreement dated August
11, 1998 (the "Stock Option Agreement') with the Issuer pursuant to which, among
other things, Crane has the irrevocable right,  exercisable upon the termination
of the Merger Agreement under certain circumstances, to purchase from the Issuer
up to 997,633 newly issued shares of the common stock,  par value $.01 per share
("Common Stock"),  and (ii) Shareholder  Agreements,  each dated August 11, 1998
(the  "Shareholder  Agreements"),  with certain  shareholders of the Issuer (the
"Selling  Shareholders")  pursuant to which each Selling Shareholder has agreed,
among other things,  that (x) each Selling Shareholder will tender the shares of
Common Stock owned by it in the Offer and (y) each Selling Shareholder will vote
or grant a consent or approval  with respect to all shares of Common Stock owned
by it in  favor  of  approval  of the  Merger  Agreement  and the  Stock  Option
Agreement and the  transactions  contemplated  thereby,  and against any action,
omission or agreement  which would impede or interfere  with, or have the effect
of  discouraging,  any transaction  other than the Merger.  Any shares of Common
Stock that a Selling Shareholder may subsequently  acquire  automatically become
subject to the Shareholder  Agreement.  Pursuant to each Shareholder  Agreement,
each Selling  Shareholder  has agreed that,  upon the request of Crane,  it will
deliver a proxy to Crane to vote,  or grant a consent or approval in respect of,
the shares of Common Stock owned by it. Each of the Merger Agreement,  the Stock
Option  Agreement and the Shareholder  Agreements is described more fully in the

Rights  Agreement,  dated  as of  October  6,  1997,  between  the  Company  and
StockTrans,  Inc., as Rights Agent (as amended,  the "Rights  Agreement"),  at a
purchase price of $3.50 per Share (and associated  Right),  net to the seller in
cash,  without  interest  thereon (the "Per Share  Amount"),  upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the related
Letter of  Transmittal  (which  together  constitute  the  "Offer").  Unless the
context  otherwise  requires,   all  references  to  Shares  shall  include  the
associated Rights.

   Tendering  shareholders  will  not be  obligated  to pay  brokerage  fees  or
commissions  or,  except  as  set  forth  in  Instruction  6 of  the  Letter  of
Transmittal,  stock  transfer  taxes on the purchase of Shares by the  Purchaser
pursuant to the Offer.  The Purchaser will pay all charges and expenses of First
Chicago Trust Company of New York, as Depositary (the "Depositary"),  and Beacon
Hill Partners, Inc., as Information Agent (the "Information Agent"), incurred in
connection with the Offer. See Section 16.

   THE  BOARD OF  DIRECTORS  OF THE  COMPANY  HAS  DETERMINED  THAT  EACH OF THE
TRANSACTIONS  CONTEMPLATED BY THE MERGER AGREEMENT,  INCLUDING THE OFFER AND THE
MERGER (AS SUCH TERMS ARE DEFINED HEREIN),  IS FAIR TO AND IN THE BEST INTERESTS
OF THE COMPANY AND ITS  SHAREHOLDERS,  HAS APPROVED THE OFFER AND THE MERGER AND
RECOMMENDS ACCEPTANCE OF THE OFFER BY THE COMPANY'S SHAREHOLDERS.

   Legg Mason Wood Walker Incorporated  ("Legg Mason"),  the Company's financial
advisor,  has  delivered  to the  Board of  Directors  of the  Company a written
opinion dated August 10, 1998 to the effect that,  as of such date,  each of the
consideration  to be received by the holders of Shares pursuant to the Offer and
the Merger is fair to the Company's shareholders from a financial point of view.
A    copy    of    such    opinion    is    included    with    the    Company's
Solicitation/Recommendation  Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which is being mailed to shareholders  concurrently  herewith,  and shareholders
are  urged  to  read  the  opinion  in its  entirety  for a  description  of the
assumptions made, matters considered and limitations of the review undertaken by
Legg Mason.

   THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, AT LEAST A MAJORITY OF THE
TOTAL  NUMBER OF  OUTSTANDING  SHARES ON A FULLY  DILUTED  BASIS  BEING  VALIDLY
TENDERED PRIOR TO THE EXPIRATION DATE (AS DEFINED IN SECTION 1) AND NOT PROPERLY
WITHDRAWN (THE "MINIMUM CONDITION").  THE OFFER IS ALSO SUBJECT TO CERTAIN OTHER
TERMS AND CONDITIONS.  THE OFFER WILL EXPIRE AT 12:00 MIDNIGHT, EASTERN TIME, ON
FRIDAY, SEPTEMBER 11, 1998, UNLESS EXTENDED. SEE SECTIONS 1, 14, AND 15 BELOW.

   The Offer is being made pursuant to the  Agreement and Plan of Merger,  dated
as of August 11, 1998 (the "Merger Agreement"), among the Company, the Purchaser
and Crane  pursuant to which,  following the  consummation  of the Offer and the
satisfaction or waiver of certain conditions,  the Purchaser will be merged with
and  into  the  Company  (the  "Merger"),  with the  Company  continuing  as the
surviving  corporation  (the  "Surviving  Corporation").  In  the  Merger,  each
outstanding  Share (other than Shares held by Crane, the Purchaser or any wholly
owned  subsidiary  of Crane or Purchaser or held in the treasury of the Company,
which will be canceled  with no payment  being made with  respect  thereto,  and
other than Shares,  if any,  held by  shareholders  who object to the Merger and
demand a right to receive payment of the fair value of such shareholders' Shares
in accordance with Pennsylvania law, unless such right shall have been withdrawn
or  otherwise  lost  ("Dissenting  Shares"))  will,  by virtue of the Merger and
without any action by the holder thereof, be converted into the right to receive
$3.50 in cash (the "Merger

                                1
<PAGE>
Consideration"),  payable to the holder thereof,  without  interest thereon upon
the  surrender  of  the  certificate   formerly   representing  such  Share.  In
conjunction  with  the  Merger  Agreement,  Crane  entered  into a Stock  Option
Agreement (the "Stock Option  Agreement") with the Company pursuant to which the
Company has  granted  Crane an option to  purchase  up to 997,633  newly  issued
shares (or,  based on  information  supplied to the  Purchaser  by the  Company,
approximately  19.9% of the outstanding Shares as of August 11, 1998) of Company
Common  Stock,   and  Crane  has  entered  into   Shareholder   Agreements  (the
"Shareholder  Agreements") with certain  shareholders of the Company  (including
certain  directors and officers of the Company) holding in the aggregate 982,072
Shares (or,  based on  information  supplied to the  Purchaser  by the  Company,
approximately  19.6% of the outstanding Shares as of August 11, 1998),  pursuant
to which such  shareholders  have,  among other  things,  agreed to tender their
Shares pursuant to the Offer. The Merger  Agreement,  the Stock Option Agreement
and the  Shareholder  Agreements  are more fully  described in Section 11 below.
Certain U.S.  federal income tax  consequences of the sale of Shares pursuant to
the Offer and the Merger, as the case may be, are described in Section 5 below.

   The  Pennsylvania   Business   Corporation  Law  (the  "PBCL")  requires  the
affirmative  vote of holders of at least a majority of the votes cast by holders
of Shares to approve the Merger.  As a result,  if the Minimum Condition and the
other  conditions to the Offer are satisfied and the Offer is  consummated,  the
Purchaser will own a sufficient  number of Shares to ensure that the Merger will
be approved.  Under the PBCL, if after  consummation  of the Offer the Purchaser
owns at least 80% of the Shares then outstanding,  the Purchaser will be able to
cause the  Merger to occur  without a vote of the  Company's  shareholders.  If,
however,  after  consummation of the Offer,  the Purchaser owns less than 80% of
the  then  outstanding  Shares,  a vote of the  Company's  shareholders  will be
required under the PBCL to approve the Merger, and a significantly longer period
of time will be required to effect the Merger. See Section 11.

   The Company has informed the  Purchaser  that,  as of August 11, 1998,  there
were 5,013,233  Shares issued and outstanding and 1,154,000  Shares reserved for
issuance  upon the exercise of  outstanding  options to acquire  Company  Common
Stock  ("Options")  granted pursuant to the Company's 1992 Stock Option Plan and
1988 Stock Option Plan.

   No dissenters'  rights are available in connection  with the Offer;  however,
shareholders  will  have  dissenters'  rights  in  connection  with  the  Merger
regardless  of whether the Merger is  consummated  with or without a vote of the
Company's shareholders. See Section 11.

   THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS
MADE WITH RESPECT TO THE OFFER.

1. TERMS OF THE OFFER

   Upon the terms and subject to the conditions of the Offer (including,  if the
Offer is extended or amended,  the terms and conditions of any such extension or
amendment), the Purchaser will accept for payment and pay for all Shares validly
tendered on or prior to the Expiration Date (as defined below) and not withdrawn
in accordance with the procedures set forth in Section 4, as soon as practicable
after such Expiration Date; provided that, if all of the conditions to the Offer
are satisfied and more than 65% but less than 80% of the  outstanding  shares of
Company  Common  Stock on a fully  diluted  basis  (including  shares of Company
Common Stock  issuable upon exercise of  outstanding  Options) have been validly
tendered and not withdrawn in the Offer,  the Purchaser  reserves the right,  in
its sole  discretion,  to extend the Offer from time to time for up to a maximum
of ten  additional  business  days  in the  aggregate  for all  such  extensions
provided the Purchaser  agrees to waive the  conditions  set forth in paragraphs
(c),  (f) and (g) of  Section  14.  The Offer  shall  remain  open  until  12:00
midnight,  Eastern time, on Friday,  September 11, 1998 (the "Expiration Date"),
unless the Purchaser  shall have extended the period of time for which the Offer
is open,  in which event the term  "Expiration  Date" shall mean the latest time
and date at which the Offer, as so extended by the Purchaser,  shall expire. If,
at any  Expiration  Date,  the  conditions to the Offer  described in Section 14
hereof shall not have been satisfied or waived, the Purchaser reserves the right
(but  shall not be  obligated)  to extend  the Offer from time to time by giving
oral or written notice to the Depositary.  During any such extension, all Shares
previously  tendered  and not  withdrawn  will  remain  subject to the Offer and
subject to the right of a tendering  shareholder to withdraw such  shareholder's
Shares. See Section 4.

                                2
<PAGE>
   Subject  to  the  applicable  regulations  of  the  Securities  and  Exchange
Commission (the "Commission"),  the Purchaser also expressly reserves the right,
in its sole  discretion,  at any time or from time to time, to (i) terminate the
Offer if any condition  referred to in Section 14 has not been  satisfied by any
Expiration  Date and return all tendered  Shares;  (ii) waive any condition;  or
(iii) except as set forth in the Merger Agreement,  otherwise amend the Offer in
any respect, in each case, by giving oral or written notice of such termination,
waiver or amendment to the Depositary.  In the Merger  Agreement,  the Purchaser
has agreed that,  without the prior written consent of the Company,  it will not
(i) decrease the price per Share or change the form of consideration  payable in
the Offer,  (ii)  decrease  the number of Shares  sought to be  purchased in the
Offer,  (iii) impose additional  conditions to the Offer or (iv) amend any other
term of the Offer in any manner adverse to the holders of Shares.

   Any such extension,  termination or amendment will be followed as promptly as
practicable by public announcement thereof, and such announcement in the case of
an extension  will be made no later than 9:00 a.m.,  Eastern  time,  on the next
business day after the previously  scheduled  Expiration Date.  Without limiting
the manner in which the  Purchaser  may choose to make any public  announcement,
subject to  applicable  law  (including  Rules  14d-4(c) and 14d-6(d)  under the
Securities  Exchange Act of 1934, as amended (the "Exchange Act"), which require
that  material  changes be  promptly  disseminated  to holders of  Shares),  the
Purchaser   shall  have  no  obligation  to  publish,   advertise  or  otherwise
communicate any such public  announcement other than by issuing a release to the
Dow Jones News  Service.  The rights  reserved by the Purchaser in the preceding
paragraph are in addition to the Purchaser's rights described in Section 14.

   If the Purchaser  makes a material change in the terms of the Offer, or if it
waives a material  condition to the Offer,  the Purchaser  will extend the Offer
and  disseminate  additional  tender offer  materials to the extent  required by
Rules  14d-4(c),  14d-6(d) and 14e-l under the Exchange Act. The minimum  period
during which an offer must remain open following  material  changes in the terms
of the  Offer,  other  than a  change  in price or a  change  in  percentage  of
securities sought,  will depend upon the facts and circumstances,  including the
materiality  of the changes.  In the  Commission's  view, an offer should remain
open for a minimum of five  business  days from the date the material  change is
first  published,  sent or given to  shareholders,  and, if material changes are
made with respect to information  that approaches the  significance of price and
the  percentage  of  securities  sought,  a minimum of ten business  days may be
required to allow for adequate dissemination and investor response. With respect
to a change in price,  a minimum ten  business  day period from the date of such
change is generally  required under applicable  Commission rules and regulations
to allow for adequate dissemination to shareholders.  For purposes of the Offer,
a "business day" means any day other than a Saturday,  Sunday or a U.S.  federal
holiday and consists of the time period from 12:01 a.m.  through 12:00 midnight,
Eastern time.

   As of the date of this Offer to  Purchase,  the Rights are  evidenced  by the
certificates  representing Shares (each, a "Share Certificate") and do not trade
separately.  Accordingly,  by tendering a Share  Certificate,  a shareholder  is
automatically  tendering the associated  Rights.  If,  however,  pursuant to the
Rights  Agreement  or for any other  reason,  the  Rights  detach  and  separate
certificates   representing   Rights   ("Rights   Certificates")   are   issued,
shareholders  will be  required  to tender one Right for each Share  tendered in
order to effect a valid tender of such Share.

   The Company has provided the Purchaser with the Company's  shareholder  lists
and security  position  listings for the purpose of  disseminating  the Offer to
holders of Shares. This Offer to Purchase, the related Letter of Transmittal and
other  relevant  materials  will be mailed by the Purchaser to record holders of
Shares and will be furnished by the  Purchaser to brokers,  dealers,  commercial
banks,  trust  companies and similar  persons whose names, or the names of whose
nominees,  appear on the shareholder lists or, if applicable,  who are listed as
participants in a clearing agency's  security  position listing,  for subsequent
transmittal to beneficial owners of Shares.

2. ACCEPTANCE FOR PAYMENT AND PAYMENT

   Upon the terms and subject to the conditions of the Offer (including,  if the
Offer is  extended  or  amended,  the  terms and  conditions  of the Offer as so
extended or amended), the Purchaser will purchase, by accepting for payment, and
will pay for, all Shares validly tendered and not properly withdrawn (in

                                3
<PAGE>
accordance  with Section 4) prior to the Expiration  Date as soon as practicable
after the  Expiration  Date.  See  Sections  1 and 14. In  addition,  subject to
applicable rules of the Commission,  the Purchaser  expressly reserves the right
to delay  acceptance  for payment of, or payment for,  Shares in order to comply
with applicable law, including the Hart-Scott-Rodino  Antitrust Improvements Act
of 1976, as amended, and the regulations thereunder (the "HSR Act"). See Section
15.

   In all cases, payment for Shares purchased pursuant to the Offer will be made
only after timely receipt by the Depositary of (i) Share  Certificates or timely
confirmation (a "Book-Entry  Confirmation")  of the book-entry  transfer of such
Shares  into the  Depositary's  account at The  Depository  Trust  Company  (the
"Book-Entry  Transfer Facility") pursuant to the procedures set forth in Section
3; (ii) the appropriate Letter of Transmittal (or a facsimile thereof), properly
completed  and duly  executed,  with any  required  signature  guarantees  or an
Agent's Message (as defined below) in connection with a book-entry transfer; and
(iii) any other documents required by the Letter of Transmittal.

   The term "Agent's  Message"  means a message  transmitted  by the  Book-Entry
Transfer  Facility to, and received by, the  Depositary  and forming a part of a
Book-Entry Confirmation,  which states that the Book-Entry Transfer Facility has
received  an  express  acknowledgment  from the  participant  in the  Book-Entry
Transfer Facility  tendering the Shares which are the subject of such Book-Entry
Confirmation  that such  participant  has received and agrees to be bound by the
terms of the Letter of  Transmittal  and that the  Purchaser  may  enforce  such
agreement against such participant.

   For purposes of the Offer,  the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not withdrawn as, if
and when the  Purchaser  gives oral or written  notice to the  Depositary of the
Purchaser's  acceptance of such Shares for payment pursuant to the Offer. In all
cases,  upon the terms and subject to the  conditions of the Offer,  payment for
Shares  purchased  pursuant to the Offer will be made by deposit of the purchase
price  therefor  with the  Depositary,  which  will act as agent  for  tendering
shareholders  for the  purpose  of  receiving  payment  from the  Purchaser  and
transmitting payment to validly tendering shareholders.

   UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE FOR SHARES BE PAID
BY THE PURCHASER.

   If any  tendered  Shares  are not  purchased  pursuant  to the  Offer for any
reason, or if Share Certificates are submitted representing more Shares than are
tendered, Share Certificates  representing unpurchased or untendered Shares will
be returned,  without expense to the tendering  shareholder  (or, in the case of
Shares  delivered by book-entry  transfer into the  Depositary's  account at the
Book-Entry  Transfer Facility pursuant to the procedures set forth in Section 3,
such Shares will be credited  to an account  maintained  within such  Book-Entry
Transfer  Facility),  as  promptly  as  practicable  following  the  expiration,
termination or withdrawal of the Offer.

   IF,  PRIOR  TO  THE  EXPIRATION   DATE,  THE  PURCHASER  SHALL  INCREASE  THE
CONSIDERATION OFFERED TO HOLDERS OF SHARES PURSUANT TO THE OFFER, SUCH INCREASED
CONSIDERATION SHALL BE PAID TO ALL HOLDERS OF SHARES THAT ARE PURCHASED PURSUANT
TO THE OFFER, WHETHER OR NOT SUCH SHARES WERE TENDERED PRIOR TO SUCH INCREASE IN
CONSIDERATION.

   The  Purchaser  reserves the right,  subject to the  provisions of the Merger
Agreement,  to assign,  in whole or from time to time in part, to one or more of
Crane's  subsidiaries  or affiliates the right to purchase all or any portion of
the Shares tendered  pursuant to the Offer,  but no such assignment will relieve
Crane of any liability  under the Merger  Agreement for any breach of the Merger
Agreement by any such assignee.

3. PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES.

   Valid Tender of Shares.  Except as set forth below, in order for Shares to be
validly  tendered  pursuant  to the  Offer,  the  Letter  of  Transmittal  (or a
facsimile  thereof),  properly  completed and duly  executed,  together with any
required  signature  guarantees,  or an  Agent's  Message in  connection  with a
book-entry delivery of Shares, and any other documents required by the Letter of
Transmittal must be

                                4
<PAGE>
received by the  Depositary  at one of its addresses set forth on the back cover
of this  Offer to  Purchase  on or prior to the  Expiration  Date and either (i)
Share  Certificates  representing  tendered  Shares  must  be  received  by  the
Depositary or tendered  pursuant to the procedure  for  book-entry  transfer set
forth below and Book-Entry  Confirmation must be received by the Depositary,  in
each case on or prior to the Expiration  Date, or (ii) the  guaranteed  delivery
procedures set forth below must be complied with.

   THE  METHOD  OF  DELIVERY  OF SHARE  CERTIFICATES,  RIGHTS  CERTIFICATES  (IF
APPLICABLE),  THE LETTER OF TRANSMITTAL  AND ALL OTHER REQUIRED  DOCUMENTS IS AT
THE OPTION AND SOLE RISK OF THE  TENDERING  SHAREHOLDER,  AND  DELIVERY  WILL BE
DEEMED MADE ONLY WHEN  ACTUALLY  RECEIVED BY THE  DEPOSITARY.  IF DELIVERY IS BY
MAIL,  REGISTERED  MAIL WITH RETURN  RECEIPT  REQUESTED,  PROPERLY  INSURED,  IS
RECOMMENDED.  IN ALL CASES,  SUFFICIENT  TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.

   Book-Entry  Transfer.  The  Depositary  will make a request to  establish  an
account  with  respect to the Shares at the  Book-Entry  Transfer  Facility  for
purposes of the Offer within two  business  days after the date of this Offer to
Purchase.  Any financial  institution that is a participant in the system of the
Book-Entry  Transfer Facility may make book-entry  delivery of Shares by causing
the Book-Entry  Transfer  Facility to transfer such Shares into the Depositary's
account at the Book-Entry  Transfer  Facility in accordance  with the Book-Entry
Transfer Facility's procedures for the transfer. Although delivery of Shares may
be effected through  book-entry  transfer into the  Depositary's  account at the
Book-Entry Transfer Facility,  the Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees, or
an Agent's  Message in  connection  with a  book-entry  transfer,  and any other
required  documents  must,  in any case, be  transmitted  to and received by the
Depositary  at one of its addresses set forth on the back cover of this Offer to
Purchase  on or  prior  to  the  Expiration  Date,  or the  guaranteed  delivery
procedure set forth below must be complied with.

   DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE
WITH THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE
DELIVERY TO THE DEPOSITARY.

   Signature  Guarantees.  Signatures  on all  Letters  of  Transmittal  must be
guaranteed  by a firm that is a bank,  broker,  dealer,  credit  union,  savings
association or other entity which is a member in good standing of the Securities
Transfer Agents Medallion Program (an "Eligible Institution"), unless the Shares
tendered  thereby are tendered (i) by a registered  holder of Shares who has not
completed  either the box  labeled  "Special  Payment  Instructions"  or the box
labeled "Special Delivery Instructions" on the Letter of Transmittal or (ii) for
the  account of an  Eligible  Institution.  See  Instruction  1 of the Letter of
Transmittal.

   If the Share  Certificates  are registered in the name of a person other than
the  signer of the  Letter of  Transmittal,  or if  payment is to be made to, or
Share  Certificates  for  unpurchased  Shares are to be issued or returned to, a
person other than the registered  holder,  then the tendered Share  Certificates
must be endorsed or accompanied by appropriate  stock powers,  signed exactly as
the name or names of the  registered  holder  or  holders  appear  on the  Share
Certificates,  with the  signatures  on the Share  Certificates  or stock powers
guaranteed by an Eligible  Institution as provided in the Letter of Transmittal.
See Instructions 1 and 5 of the Letter of Transmittal.

   If the Share  Certificates  are  forwarded  separately to the  Depositary,  a
properly completed and duly executed Letter of Transmittal (or a manually signed
facsimile thereof) must accompany each such delivery.

   Guaranteed  Delivery.  If a shareholder  desires to tender Shares pursuant to
the  Offer  and  such  shareholder's  Share  Certificates  are  not  immediately
available or time will not permit all required documents to reach the Depositary
on or prior to the Expiration  Date or the  procedures  for book-entry  transfer
cannot be completed on a timely basis,  such Shares may nevertheless be tendered
if all of the following guaranteed delivery procedures are duly complied with:

     (i) such tender is made by or through an Eligible Institution;

                                5
<PAGE>
     (ii) a properly completed and duly executed Notice of Guaranteed  Delivery,
    substantially  in the form made available by the  Purchaser,  is received by
    the Depositary, as provided below, on or prior to the Expiration Date; and

     (iii) the Share  Certificates (or a Book-Entry  Confirmation)  representing
    all tendered  Shares,  in proper form for transfer  together with a properly
    completed  and duly executed  Letter of  Transmittal  (or a manually  signed
    facsimile thereof),  with any required signature guarantees (or, in the case
    of a  book-entry  transfer,  an  Agent's  Message)  and any other  documents
    required by the Letter of Transmittal are received by the Depositary  within
    three  Nasdaq  National  Market  trading days after the date of execution of
    such Notice of Guaranteed Delivery.

   The  Notice  of  Guaranteed  Delivery  may be  delivered  by  hand or mail or
transmitted  by  facsimile  transmission  to the  Depositary  and must include a
guarantee  by an  Eligible  Institution  in the form set forth in such Notice of
Guaranteed  Delivery and a  representation  that the shareholder on whose behalf
the tender is being made is deemed to own the Shares being  tendered  within the
meaning of Rule 14e-4 under the Exchange Act.

   Notwithstanding  any other provision hereof,  payment for Shares accepted for
payment  pursuant  to the  Offer  will in all cases be made  only  after  timely
receipt  by  the  Depositary  of  Share   Certificates  for,  or  of  Book-Entry
Confirmation  with  respect  to,  such  Shares,  a properly  completed  and duly
executed  Letter  of  Transmittal  (or a  manually  signed  facsimile  thereof),
together with any required signature guarantees (or, in the case of a book-entry
transfer,  an Agent's Message) and any other documents required by the Letter of
Transmittal.   Accordingly,   payment   might  not  be  made  to  all  tendering
shareholders at the same time, and will depend upon when Share  Certificates are
received  by the  Depositary  or  Book-Entry  Confirmations  of such  Shares are
received into the Depositary's account at the Book-Entry Transfer Facility.

   Backup U.S.  Federal Income Tax  Withholding.  Under the backup U.S.  federal
income tax  withholding  laws  applicable  to certain  shareholders  (other than
certain exempt  shareholders,  including,  among others,  all  corporations  and
certain foreign individuals),  the Depositary may be required to withhold 31% of
the amount of any payments made to such  shareholders  pursuant to the Offer. To
prevent backup U.S. federal income tax  withholding,  each such shareholder must
provide the Depositary with such shareholder's  correct taxpayer  identification
number and certify that such  shareholder is not subject to backup U.S.  federal
income tax  withholding by completing  the  Substitute  Form W-9 included in the
Letter of Transmittal. See Instruction 9 of the Letter of Transmittal.

   Appointment  as Proxy.  By executing the Letter of  Transmittal,  a tendering
shareholder  irrevocably appoints designees of the Purchaser,  and each of them,
as such shareholder's agents,  attorneys-in-fact and proxies, with full power of
substitution,  in the manner set forth in the Letter of Transmittal, to the full
extent of such shareholder's  rights with respect to the Shares tendered by such
shareholder  and accepted for payment by the  Purchaser  and with respect to any
and all other  Shares  and other  securities  or rights  issued or  issuable  in
respect of such Shares on or after the date of this Offer to Purchase.  All such
powers of attorney and proxies shall be considered  irrevocable and coupled with
an interest in the tendered Shares.  Such appointment will be effective upon the
acceptance  for payment of such Shares by the Purchaser in  accordance  with the
terms of the  Offer.  Upon such  acceptance  for  payment,  all other  powers of
attorney and proxies given by such  shareholder  with respect to such Shares and
such other  securities or rights prior to such payment will be revoked,  without
further action, and no subsequent powers of attorney and proxies may be given by
such shareholder (and, if given, will not be deemed effective). The designees of
the Purchaser  will,  with respect to the Shares and such other  securities  and
rights for which such  appointment  is  effective,  be empowered to exercise all
voting and other rights of such shareholder as they in their sole discretion may
deem proper at any annual or special meeting of the Company's  shareholders,  or
any  adjournment  or  postponement  thereof,  or by  consent in lieu of any such
meeting  or  otherwise.  In order  for  Shares to be  deemed  validly  tendered,
immediately upon the acceptance for payment of such Shares, the Purchaser or its
designee must be able to exercise full voting rights with respect to such Shares
and other securities, including voting at any meeting of shareholders.

                                6

   Determination of Validity.  All questions as to the form of documents and the
validity,  eligibility (including time of receipt) and acceptance for payment of
any  tender  of  Shares  will  be  determined  by the  Purchaser,  in  its  sole
discretion,  whose determination shall be final and binding on all parties.  The
Purchaser reserves the absolute right to reject any or all tenders determined by
it not to be in proper  form or the  acceptance  of or payment for which may, in
the opinion of the Purchaser's counsel, be unlawful. The Purchaser also reserves
the absolute  right to waive any of the conditions of the Offer or any defect or
irregularity  in any tender of Shares of any particular  shareholder  whether or
not  similar  defects  or  irregularities  are  waived  in  the  case  of  other
shareholders.

   The Purchaser's  interpretation of the terms and conditions of the Offer will
be final and  binding.  No tender of Shares will be deemed to have been  validly
made until all defects and irregularities  with respect to such tender have been
cured or waived by the Purchaser.  None of Crane,  the Purchaser or any of their
respective  affiliates or assigns, the Depositary,  the Information Agent or any
other  person or entity will be under any duty to give any  notification  of any
defects or  irregularities in tenders or incur any liability for failure to give
any such notification.

   The Purchaser's  acceptance for payment of Shares tendered pursuant to any of
the procedures  described above will constitute a binding  agreement between the
tendering  shareholder  and the  Purchaser  upon the  terms and  subject  to the
conditions of the Offer.

4. WITHDRAWAL RIGHTS.

   Except as  otherwise  provided  in this  Section 4,  tenders  of Shares  made
pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer may
be  withdrawn  at any  time on or  prior  to the  Expiration  Date  and,  unless
theretofore  accepted for payment as provided  herein,  may also be withdrawn at
any time after Monday, October 12, 1998.

   If, for any reason whatsoever,  acceptance for payment of any Shares tendered
pursuant  to the Offer is  delayed,  or the  Purchaser  is unable to accept  for
payment  or pay  for  Shares  tendered  pursuant  to the  Offer,  then,  without
prejudice  to the  Purchaser's  rights set forth  herein,  the  Depositary  may,
nevertheless, on behalf of the Purchaser, retain tendered Shares and such Shares
may not be  withdrawn  except to the extent that the  tendering  shareholder  is
entitled to and duly exercises withdrawal rights as described in this Section 4.
Any such delay will be by an  extension  of the Offer to the extent  required by
law.

   In  order  for  a  withdrawal  to  be  effective,   a  written  or  facsimile
transmission  notice of withdrawal  must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.  Any
such notice of  withdrawal  must specify the name of the person who tendered the
Shares to be  withdrawn,  the  number of Shares to be  withdrawn,  and (if Share
Certificates have been tendered) the name of the registered holder of the Shares
as set forth in the Share Certificates, if different from that of the person who
tendered such Shares.  If Share  Certificates  have been  delivered or otherwise
identified to the Depositary,  then prior to the physical  release of such Share
Certificates,  the tendering shareholder must submit the serial numbers shown on
the particular Share Certificates  evidencing the Shares to be withdrawn and the
signature  on the  notice  of  withdrawal  must  be  guaranteed  by an  Eligible
Institution,  except  in the  case of  Shares  tendered  for the  account  of an
Eligible  Institution.  If Shares have been tendered  pursuant to the procedures
for  book-entry  transfer set forth in Section 3, the notice of withdrawal  must
specify the name and number of the account at the Book-Entry  Transfer  Facility
to be credited with the withdrawn  Shares,  in which case a notice of withdrawal
will be  effective  if  delivered  to the  Depositary  by any method of delivery
described in the first sentence of this paragraph. Withdrawals of Shares may not
be rescinded.  Any Shares properly withdrawn will be deemed not validly tendered
for purposes of the Offer,  but may be tendered at any subsequent  time prior to
the Expiration Date by following any of the procedures described in Section 3.

   All  questions  as to the form and  validity  (including  time of receipt) of
notices  of  withdrawal  will  be  determined  by the  Purchaser,  in  its  sole
discretion,  whose determination shall be final and binding.  None of Crane, the
Purchaser or any of their respective affiliates or assigns, the Depositary,  the
Information  Agent or any other  person or entity will be under any duty to give
any notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give any such notification.

5. CERTAIN TAX CONSEQUENCES

   Sales  of  Shares  pursuant  to  the  Offer  (and  the  receipt  of  cash  by
shareholders of the Company pursuant to the Merger) will be taxable transactions
for U.S. federal income tax purposes under the Internal Revenue Code of 1986, as
amended (the  "Code"),  and may also be taxable  transactions  under  applicable
state, local,  foreign and other tax laws. For U.S. federal income tax purposes,
a  tendering  shareholder  will  generally  recognize  gain or loss equal to the
difference  between the amount of cash received by the  shareholder  pursuant to
the Offer (or pursuant to the Merger) and the  aggregate tax basis in the Shares
tendered by the  shareholder  and  purchased  pursuant to the Offer (or canceled
pursuant to the Merger).  Gain or loss will be  calculated  separately  for each
block of Shares  tendered  and  purchased  pursuant  to the  Offer (or  canceled
pursuant to the Merger).

   If tendered  Shares are held by a tendering  shareholder  as capital  assets,
gain or loss  recognized  by the tendering  shareholder  will be capital gain or
loss,   which  will  be  long-term   capital  gain  or  loss  if  the  tendering
shareholder's  holding period for the Shares exceeds one year. Long-term capital
gains recognized by a tendering  individual  shareholder will generally be taxed
at a maximum U.S. federal marginal tax rate of 20%, and long-term  capital gains
recognized by a tendering corporate  shareholder will be taxed at a maximum U.S.
federal marginal tax rate of 35%.

   THE  FOREGOING  DISCUSSION  MAY NOT BE  APPLICABLE  WITH  RESPECT  TO  SHARES
RECEIVED  PURSUANT TO THE  EXERCISE OF EMPLOYEE  STOCK  OPTIONS OR  OTHERWISE AS
COMPENSATION OR WITH RESPECT TO HOLDERS OF SHARES WHO ARE SUBJECT TO SPECIAL TAX
TREATMENT UNDER THE CODE, SUCH AS NON-U.S.  PERSONS,  LIFE INSURANCE  COMPANIES,
TAX-EXEMPT  ORGANIZATIONS  AND  FINANCIAL  INSTITUTIONS,  AND MAY NOT APPLY TO A
HOLDER OF  SHARES IN LIGHT OF ITS  INDIVIDUAL  CIRCUMSTANCES.  SHAREHOLDERS  ARE
URGED TO  CONSULT  THEIR  OWN TAX  ADVISORS  TO  DETERMINE  THE  PARTICULAR  TAX
CONSEQUENCES TO THEM  (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE,  LOCAL
OR FOREIGN INCOME AND OTHER TAX LAWS) OF THE OFFER AND THE MERGER.

   SHAREHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE SHARES.

7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; NASDAQ NATIONAL MARKET
   LISTING; MARGIN REGULATIONS; EXCHANGE ACT REGISTRATION

   The purchase of Shares pursuant to the Offer will reduce the number of Shares
that  might  otherwise  trade  publicly  and may reduce the number of holders of
Shares,  which could  adversely  affect the  liquidity  and market  value of the
remaining  Shares held by shareholders  other than the Purchaser.  The Purchaser
cannot  predict  whether  the  reduction  in the  number  of Shares  that  might
otherwise  trade  publicly  would have an adverse  or  beneficial  effect on the
market  price for, or  marketability  of, the Shares or whether  such  reduction
would cause future market prices to be greater or less than the Offer price.

   Depending  upon the number of Shares  purchased  pursuant  to the Offer,  the
Shares may no longer be eligible for  quotation on the Nasdaq  National  Market.
If, as a result of the purchase of Shares  pursuant to the Offer,  the Shares no
longer meet the criteria for quotation on the Nasdaq National Market, the market
for the Shares could be  adversely  affected.  According to the Nasdaq  National
Market's  published  guidelines,  in order  for the  Shares to be  eligible  for
continued  quotation on the Nasdaq National  Market,  there must continue to be,
among other things, either (i) at least 750,000 publicly held Shares, held by at
least 400 round lot  shareholders,  with a market value of at least  $5,000,000,
net  tangible  assets of at least  $4,000,000  and at least two  registered  and
active market makers for the Shares,  or (ii) at least  1,100,000  publicly held
Shares,  held by at least 400 round lot shareholders,  with a market value of at
least $15,000,000,  either (x) market  capitalization of at least $50,000,000 or
(y) total assets and total  revenue of  $50,000,000  each for the most  recently
completed  fiscal year or two of the last three most recently  completed  fiscal
years,  and at least four  registered  and active  market makers for the Shares.
Shares held directly or indirectly by directors,  officers or beneficial  owners
of more than 10% of the Shares are not  considered  as being  publicly  held for
this purpose.  If the Shares were no longer eligible for quotation on the Nasdaq
National  Market,  they may  nevertheless  continue to be included in the Nasdaq
SmallCap Market unless,  among other things,  the number of publicly held Shares
(excluding Shares held by officers, directors and beneficial owners of more than
10% of the Shares) was less than 100,000, or there were fewer than 300 round lot
holders in total.  If the Shares are no longer  eligible  for  inclusion  in the
Nasdaq National Market or the Nasdaq SmallCap Market,  the Shares might still be
quoted on the OTC Bulletin Board. The extent of the public market for the Shares
and availability of such quotations would, however,  depend upon such factors as
the number of holders  and/or the  aggregate  market value of the  publicly-held
Shares at such time,  the interest in  maintaining a market in the Shares on the
part of securities firms, the possible termination of registration of the Shares
under the Exchange Act and other factors.  According to the Company,  there were
approximately 184 holders of record of Shares as of August 12, 1998.

   The Shares are currently "margin  securities" under the rules of the Board of
Governors of the Federal Reserve System (the "Federal Reserve Board"), which has
the effect,  among other  things,  of allowing  brokers to extend  credit on the
collateral  of the Shares for the  purpose  of  buying,  carrying  or trading in
securities ("purpose loans").  Depending upon factors similar to those described
above with respect to listing and market quotations,  the Shares might no longer
constitute  "margin  securities" for the purposes of the Federal Reserve Board's
margin  regulations  and,  therefore,  could no longer be used as collateral for
purpose loans made by brokers.

   The Shares are currently  registered  under the Exchange Act. The purchase of
Shares  pursuant  to the Offer may result in the Shares  becoming  eligible  for
deregistration  under  the  Exchange  Act.  Registration  of the  Shares  may be
terminated  upon  application of the Company to the Commission if the Shares are
not listed on a national securities exchange and there are fewer than 300 record
holders.  The  termination of the  registration of the Shares under the Exchange
Act would substantially reduce the information

                                9
<PAGE>
required to be  furnished by the Company to holders of the Shares and would make
certain  provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b),  the requirement of furnishing a proxy statement in
connection with shareholders' meetings, and the requirements of Rule 13e-3 under
the  Exchange  Act with  respect  to  "going  private"  transactions,  no longer
applicable to the Shares.  Furthermore,  "affiliates" of the Company and persons
holding "restricted  securities" of the Company could be deprived of the ability
to dispose of the  securities  pursuant to Rule 144 under the  Securities Act of
1933,  as amended.  If  registration  of the Shares  under the Exchange Act were
terminated,  the Shares would no longer be "margin  securities"  or eligible for
Nasdaq  quotation.  The  Purchaser  intends  to seek to  cause  the  Company  to
terminate the  registration of the Shares as soon after the  consummation of the
Offer or the Merger as the requirements for termination of registration are met.

10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY

   Crane initially began considering the possibility of acquiring the Company in
October  1997,  after  becoming  aware  of the  filing  of a shelf  registration
statement  covering the sale from time to time in market  transactions of Shares
held by certain substantial  shareholders of the Company.  Also, in mid-November
the Company publicly reported that it faced certain  liquidity issues.  Although
these issues had been  mitigated by receipt of the proceeds from the sale of one
of the Company's businesses, Crane believed that liquidity ultimately could be a
longer-term  issue for the  Company,  creating  a  possible  opportunity  for an
acquisition by Crane. In late February,  following the Company's announcement of
continuing  operating  losses in the fourth  quarter of 1997,  Mr.  R.S.  Evans,
Chairman and Chief Executive Officer of Crane, contacted Mr. David P. Kollock, a
financial advisor based in Philadelphia,  and asked him to explore the Company's
possible  interest in a  transaction  with Crane with any contacts he had on the
Company's Board of Directors.

   During late February and early March 1998, Mr.  Kollock met  separately  with
Mr. Roland K. Bullard, II, a director of the Company,  Messrs. Anthony Moffa and
Richard Tuft,  non-management  founders of the Company with substantial holdings
of Shares,  and Mr.  Richard  Defieux,  a director of the Company,  each of whom
indicated interest in discussing a possible transaction with Crane. On March 10,
Messrs. Kollock and Evans met with Mr. Stephen Wells, a director and substantial
shareholder  of  the  Company,   who  also  expressed  interest  in  a  possible
transaction.

   A  Confidentiality  Agreement  was  signed  by Crane on March 18,  1998,  and
management  presentations  to Crane by the Company and preliminary due diligence
by Crane occurred on March 19, 1998.

During the remainder of March and early April,  Crane made a number of follow-up
requests for data from the Company,  and conducted a more detailed review of the
Company on April 2 and 3, 1998. During this period,  Mr. Kollock had a number of
discussions with Mr. Wells concerning a possible transaction.

   On May 5, 1998,  Crane  delivered  a written  indication  of  interest to the
Company to acquire the Company  (excluding the Company's  RADView business) at a
price of $4.25 per Share  payable in shares of Crane  Common  Stock or $4.50 per
Share  payable  in cash,  subject  to  satisfactory  due  diligence,  definitive
documentation  and  approval by the Boards of Directors of Crane and the Company
and  the  Company's  shareholders,  as  well  as the  receipt  of any  necessary
governmental  approvals.  Crane  subsequently  was advised  that the Company had
decided to explore other possible alternatives.

   On May 12,  1998,  the Company  issued a press  release  reporting  financial
results for the quarter ended March 31, 1998 that reflected  decreased  revenues
and earnings as compared to the first quarter of 1997. The press release further
stated  that  the  Company's  Board  of  Directors  "is  considering   strategic
alternatives  to  enhance  shareholder  value,  and that such  alternatives  may
include the sale or restructuring of all or part of the Company."

   On May 22, 1998, Mr. Evans advised Mr. Wells that he was withdrawing
Crane's May 5 proposal.

   On  June  8,  1998,  the  Company   issued  a  press  release   reporting  "a
restructuring  of the Company in an effort to reduce  operating  expenses and to
provide additional focus to their key accounts and markets."

   On June 25, 1998, Mr. Evans and Mr. Kollock met with Mr. Wells to explore
renewal of Crane's interest in a possible transaction with the Company. Mr.
Wells was advised that Crane would need to take a close look at the
then-current financial condition and operating performance of the Company in
considering whether to make a proposal.

   During  the  period  from  June 29  through  July 1,  1998,  Crane  conducted
additional due diligence with respect to the Company.

   On July 13, 1998, Crane submitted a revised indication of interest at a price
of $3.25 per  Share in cash,  to be  structured  as a tender  offer  with an 80%
minimum and a subsequent  merger to acquire  shares not  purchased in the tender
offer, and otherwise with conditions  substantially  the same as Crane's initial
proposal.  Following  discussions  with Mr. Wells subsequent to a meeting of the
Company's  Board of  Directors  on July 16,  1998,  Crane  agreed  that it would
increase its proposal to $3.50 per Share.

   Between  July 22, 1998 and August 10,  1998,  Crane and the Company and their
respective  professional  advisors negotiated the Merger Agreement.  On July 24,
1998,  the Board of Directors of Crane approved the  transaction  and authorized
management  to  negotiate  the  Merger  Agreement  and all  necessary  ancillary
documentation.

   On  August  10,  1998,  the  Board of  Directors  of the  Company  authorized
representatives  of the  Company to execute the Merger  Agreement  and the Stock
Option Agreement. The Merger Agreement and the Stock Option Agreement,  together
with the  Shareholder  Agreements,  were  executed  on August  11,  1998 and the
transaction was publicly announced on the morning of August 12, 1998.

   Other than as set forth above, there have not been any contacts, negotiations
or   transactions   between  Crane  or  the  Purchaser,   or  their   respective
subsidiaries,  or, to the best knowledge of Crane or the  Purchaser,  any of the
persons  listed in  Schedule I hereto,  on the one hand,  and the Company or its
executive  officers,  directors or affiliates,  on the other hand,  concerning a
merger,  consolidation  or  acquisition,  tender offer or other  acquisition  of
securities,  election of  directors,  or a sale or other  transfer of a material
amount of assets.

11. PURPOSE OF THE OFFER; THE MERGER AGREEMENT; THE STOCK OPTION AGREEMENT;
    THE SHAREHOLDER AGREEMENTS; DISSENTERS' RIGHTS; PLANS FOR THE COMPANY;
    THE RIGHTS

   Purpose. The purpose of the Offer and the Merger is to acquire control of,
and the entire equity interest in, the Company.

   The Merger Agreement. Following is a summary of the Merger Agreement, a
copy of which has been filed as an exhibit to the Schedule 14D-1 filed by the
Purchaser with the Commission in connection

                               13
<PAGE>
with the Offer.  Such  summary is  qualified in its entirety by reference to the
Merger Agreement. The Merger Agreement should be read in its entirety for a more
complete  description of the matters summarized below.  Defined terms used below
and not defined herein have the respective  meanings  assigned to those terms in
the Merger Agreement.

   The Merger Agreement  provides that, without the prior written consent of the
Company,  the  Purchaser  may not (i) decrease  the amount  offered per Share or
change the form of consideration  payable in the Offer, (ii) decrease the number
of  Shares  sought  to be  purchased  in  the  Offer,  (iii)  impose  additional
conditions to the Offer, or (iv) amend any other term of the Offer in any manner
adverse  to the  holders  of  Shares.  If at  any  Expiration  Date,  any of the
conditions  to the Offer are not  satisfied  or  waived  by the  Purchaser,  the
Purchaser  may extend  the Offer from time to time.  Subject to the terms of the
Offer and the Merger Agreement and the satisfaction of all the conditions to the
Offer as of any  Expiration  Date, the Purchaser will accept for payment and pay
for all Shares validly tendered and not withdrawn  pursuant to the Offer as soon
as practicable after such Expiration Date of the Offer, provided that, if all of
the conditions to the Offer are satisfied and more than 65% but less than 80% of
the  outstanding  shares  of  Company  Common  Stock  on a fully  diluted  basis
(including  shares of Company Common Stock issuable upon exercise of outstanding
Options)  have  been  validly  tendered  and not  withdrawn  in the  Offer,  the
Purchaser will have the right, in its sole discretion,  to extend the Offer from
time  to  time  for up to a  maximum  of ten  additional  business  days  in the
aggregate,  provided the Purchaser  agrees to waive the  conditions set forth in
paragraphs (c), (f) and (g) of Section 14 hereof.

   The Company has  represented to Crane in the Merger  Agreement that the Board
of Directors of the Company (the "Company Board"),  at a meeting duly called and
held,  has (i)  determined  that each of the  transactions  contemplated  by the
Merger Agreement,  including each of the Offer and the Merger, is fair to and in
the best interests of the Company and its shareholders, (ii) approved the Offer,
the Merger,  the Stock Option  Agreement and the Shareholder  Agreements,  (iii)
recommended  acceptance of the Offer and approval of the Merger Agreement by the
Company's  shareholders,  and (iv) taken all other  action  necessary  to render
Section  2538  and  Subchapter  F of  Chapter  25 of the  PBCL  and  the  Rights
inapplicable to the Offer and the Merger.  Such  recommendation and approval may
be  withdrawn,  modified or amended  only to the extent  permitted by the Merger
Agreement.  The Company further  represented that, prior to the execution of the
Merger Agreement,  Legg Mason delivered to the Company Board its written opinion
that the  consideration  to be received by the holders of Shares pursuant to the
Offer and the  Merger is fair to the  Company's  shareholders  from a  financial
point of view.

   The Merger Agreement  provides that Crane,  upon the payment by the Purchaser
for Shares pursuant to the Offer  representing at least such number of Shares as
shall  satisfy  the  Minimum  Condition,  and from time to time  thereafter,  is
entitled to  designate  such number of  directors,  rounded up to the next whole
number,  on the Company  Board as is equal to the product of the total number of
directors on the Company Board  (determined after giving effect to the directors
so elected  pursuant to this  provision)  multiplied by the percentage  that the
aggregate number of Shares  beneficially  owned by Crane or its affiliates bears
to the total number of Shares then outstanding.  The Company shall, upon request
of Crane, promptly take all actions (but specifically excluding the calling of a
shareholders'  meeting)  necessary to cause Crane's  designees to be so elected,
including,  if  necessary,  amending  the  By-laws of the Company (to the extent
permitted to be amended by the Board of Directors) and seeking the  resignations
of one or more existing directors; provided, however, that prior to the time the
Merger becomes effective (the "Effective  Time"), the Company Board shall always
have not less than two members who were  directors of the Company on the date of
the Merger Agreement ("Current  Directors") and, in Crane's sole discretion,  up
to five Current  Directors.  If the number of Current Directors is reduced prior
to the  Effective  Time below the number of Current  Directors  so  specified by
Crane due to the death or resignation  of one or more of the Current  Directors,
then the remaining  director or directors who is or are Current  Directors shall
be entitled to designate by majority action of the remaining  Current  Directors
or action of the sole remaining  Current Director,  one or more persons,  as the
case may be, that has not been  designated by, and is not an Affiliate of, Crane
to fill  such  vacancy  or  vacancies  and who  shall be  deemed  to be  Current
Directors  for all purposes of the Merger  Agreement.  Following the election or
appointment of Crane's  designees and prior to the Effective Time, any amendment
or  termination  of the Merger  Agreement by the Company,  any  extension by the
Company of the time for the performance of

                               14
<PAGE>
any of the  obligations or other acts of Crane or the Purchaser or waiver of any
of the Company's rights  thereunder,  will require the concurrence of a majority
of the directors of the Company then in office who are Current  Directors (or in
the case where there are two or fewer directors who are Current  Directors,  the
concurrence of one director who is a Current Director).

   The Merger.  The Merger  Agreement  provides that, at the Effective Time, the
Purchaser  will be merged with and into the Company.  Following the Merger,  the
separate  corporate  existence of the Purchaser  will cease and the Company will
continue as the Surviving Corporation.

   The Second Amended and Restated Articles of Incorporation of the Company,  in
the form attached to the Merger  Agreement as Exhibit 1, will be the articles of
incorporation of the Surviving Corporation,  until thereafter changed or amended
as provided  therein or by applicable  law. The By-Laws of the Company in effect
at the  Effective  Time will be the by-laws of the Surviving  Corporation  until
thereafter changed or amended as provided therein or by applicable law.

   Subject to  applicable  law,  the officers  and  directors  of the  Purchaser
immediately  prior to the  Effective  Time will be the officers  and  directors,
respectively,  of the  Surviving  Corporation  and will  hold  office  until the
earlier of their resignation or removal or until their respective successors are
duly elected and qualified.

   By virtue of the Merger  and  without  any action on the part of the  holders
thereof,  at the Effective Time,  each Share issued and outstanding  immediately
prior to the  Effective  Time  (other  than (i) any  Shares  held by Crane,  the
Purchaser, any wholly owned subsidiary of Crane or the Purchaser, or held in the
treasury of the Company,  which Shares,  by virtue of the Merger and without any
action on the part of the holder thereof,  will be canceled and retired and will
cease  to exist  with no  payment  being  made  with  respect  thereto  and (ii)
Dissenting  Shares) will be canceled and retired and will be converted  into the
right to  receive  the  Merger  Consideration  in cash,  payable  to the  holder
thereof,  without interest thereon,  upon surrender of the certificate  formerly
representing  such Share.  At the Effective  Time, each share of common stock of
the Purchaser  issued and  outstanding  immediately  prior to the Effective Time
will,  by virtue of the Merger and  without any action on the part of the holder
thereof,  be  converted  into and  become  one  validly  issued,  fully paid and
non-assessable share of common stock of the Surviving Corporation.

   The Merger Agreement  provides that, prior to the Effective Time, the Company
will take all actions  necessary  to cause (i) each  unexpired  and  unexercised
Option  that  has an  exercise  price  less  than  the Per  Share  Amount  to be
automatically  converted  at the  Effective  Time  into an  amount  equal to the
difference  between the Per Share Amount and the  exercise  price of the Option,
multiplied by the number of shares of Company Common Stock issuable  immediately
prior to the  Effective  Time upon  exercise  of the Option  (without  regard to
vesting periods or restrictions on  exercisability)  and (ii) each unexpired and
unexercised  Option that has an exercise  price equal to or greater than the Per
Share  Amount to be canceled so that no Option shall have any force or effect on
or after the Effective Time.

   The Company has agreed pursuant to the Merger  Agreement that, if required by
applicable  law in  order  to  consummate  the  Merger,  as soon as  practicable
following  the  acceptance  for payment and payment for Shares by the  Purchaser
pursuant to the Offer, it will (i) convene a special meeting of its shareholders
for the purpose of considering and taking action upon the Merger Agreement; (ii)
prepare and file with the Commission a preliminary  proxy statement  relating to
the Merger Agreement,  and use its reasonable  efforts (x) to obtain and furnish
the information required to be included by the Commission therein and to cause a
definitive  proxy  statement  (the  "Proxy  Statement")  to  be  mailed  to  its
shareholders  and (y) to obtain the  necessary  approvals  of the Merger and the
Merger Agreement by its shareholders; and (iii) subject to certain provisions of
the Merger Agreement,  include in the Proxy Statement the  recommendation of the
Company Board that  shareholders of the Company vote in favor of the approval of
the Merger and the Merger  Agreement.  Crane has agreed in the Merger  Agreement
that (x) it will vote, or cause to be voted, all of the Shares then owned by it,
the  Purchaser  or any of its other  subsidiaries  in favor of  approval  of the
Merger and the Merger Agreement and, (y) following consummation of the Offer, it
shall use its best efforts to cause the Company to take the actions described in
clauses (i), (ii) and (iii) of this  paragraph,  if such actions are required by
applicable law to consummate the Merger.

    distributions  with  respect  to  its  capital  stock,  including,   without
    limitation,  in the  case of the  Company,  the  Company  Common  Stock,  or
    purchase  or redeem  any shares of its  capital  stock,  including,  without
    limitation,  in the case of the Company,  the Company Common Stock, or agree
    to take any such action;

     (xiii) not authorize or make any single  capital  expenditure  in excess of
    $5,000 or make any capital  expenditure  if the  aggregate  of the amount of
    such  capital  expenditure  together  with the amounts of all other  capital
    expenditures since the date of the Merger Agreement shall exceed $25,000;

     (xiv) not violate any law or  regulation  applicable  to it nor violate any
    order, injunction or decree applicable to the conduct of its business;

     (xv) not increase the number of shares authorized or issued and outstanding
    of its capital  stock,  including,  without  limitation,  in the case of the
    Company,  the Company  Common Stock,  nor grant or make any pledge,  option,
    warrant, call,  commitment,  right or agreement of any character relating to
    its  capital  stock,  including,  without  limitation,  in the  case  of the
    Company,  the  Company  Common  Stock,  nor issue or sell any  shares of its
    capital stock, including, without limitation, in the case of the

<PAGE>
    Company,  the Company  Common  Stock,  or securities  convertible  into such
    capital stock, or any bonds, promissory notes, debentures or other corporate
    securities  or become  obligated so to sell or issue any such  securities or

    rights or (ii) pursuant to the Stock Option Agreement;

     (xvi)  not  make  any  change  to its  accounting  methods,  principles  or

    Produksjon in excess of $100,000 in the aggregate;

     (xviii) not waive any right of substantial value or cancel any debt owed to
    the Company or any subsidiary or claim against any person or entity; and

     (xix)  not  authorize,  or commit  or agree to take,  any of the  foregoing
    actions;

provided, however, that if the Company requests in writing that Crane consent to
the taking of any  affirmative  action on the part of the  Company the taking of
which  would  require  such  consent  pursuant  to this  section  of the  Merger
Agreement  and the failure to grant such consent  within four  business  days of
receipt  by  Crane of such  request  is the sole  cause of the  occurrence  of a
Material Adverse Effect, then such Material Adverse Effect shall not be an Event
for  purposes  of  Section  14 of this  Offer to  Purchase  nor  shall  Crane be
permitted to terminate the Merger Agreement solely due to the occurrence of such
Material Adverse Effect.

   The Merger  Agreement  also  provides that the Company will not, and will not
permit any of its  subsidiaries  to, take any action  that would,  or that could
reasonably  be  expected  to,  result  in (i)  any of  its  representations  and
warranties  set  forth  in  the  Merger  Agreement  that  are  qualified  as  to
materiality becoming untrue, (ii) any of its representations and warranties that
are not so qualified becoming untrue in any material respect or (iii) subject to
certain  of  the  Company's  rights  under  the  Merger  Agreement,  any  of the
conditions to the Merger set forth in the Merger  Agreement  that are within the
Company's control not being satisfied.

   Advice of Changes.  The Merger  Agreement  provides  that the  Company  shall
promptly  advise  Crane  orally  and in  writing  of (i) any  representation  or
warranty  made by it contained in the Merger  Agreement  that is qualified as to
materiality   becoming   untrue  or  inaccurate  in  any  respect  or  any  such
representation  or  warranty  that  is  not  so  qualified  becoming  untrue  or
inaccurate  in any  material  respect,  (ii) the failure by it to comply with or
satisfy in any  material  respect any  covenant,  condition  or  agreement to be
complied with or satisfied by it under the Merger  Agreement or (iii) any change
or event  having,  or which could  reasonably  be  expected to have,  a Material
Adverse  Effect on the Company and its  subsidiaries  taken as a whole or on the
truth of its  representations and warranties or the ability of the conditions to
the  Merger  set  forth in the  Merger  Agreement  to be  satisfied.  Upon  such
notification,  Crane and Purchaser shall have the option either to terminate the
Merger  Agreement  or to waive any right to  consider  any of the  foregoing  in
connection  with a  determination  as to whether any of the Events  specified in
subparagraphs  (c),  (f) or (g) of  Section  14 of this  Offer to  Purchase  has
occurred.

   No Solicitation.  The Merger  Agreement  provides that the Company shall not,
nor shall it permit any of its subsidiaries to, nor shall it authorize or permit
any of its directors,  officers or employees or any investment banker, financial
advisor,  attorney,  accountant or other representative retained by it or any of
its subsidiaries to, directly or indirectly  through another person, (i) solicit
or initiate  (including  by way of  furnishing  information),  or take any other
action  to  facilitate,  any  inquiries  or  the  making  of any  proposal  that
constitutes any Acquisition  Proposal (as defined below) or (ii)  participate in
any discussions or negotiations  regarding any Acquisition  Proposal;  provided,
however,  that if, at any time prior to the  acceptance for payment of shares of
Company  Common  Stock  pursuant  to the Offer,  the Board of  Directors  of the
Company determines in good faith,  based on the advice of outside counsel,  that
it is  required  to do so in order to comply  with its  fiduciary  duties to the
Company's  shareholders under applicable law, the Company may, in response to an
Acquisition Proposal that was not solicited by it, and

                               19
<PAGE>
subject to compliance  with Section  5.02(c) of the Merger  Agreement  described
below (regarding  informing Crane of the existence and terms of such Acquisition
Proposal),  (x)  furnish  information  with  respect  to  the  Company  and  its
subsidiaries to any person pursuant to a customary confidentiality agreement (as
determined by the Company after  consultation  with its outside counsel) and (y)
participate in negotiations regarding such Acquisition Proposal. For purposes of
the Merger  Agreement,  "Acquisition  Proposal"  means any inquiry,  proposal or
offer from any person relating to any direct or indirect acquisition or purchase
of 20% or more of the assets of the Company and its  subsidiaries or 20% or more
of any class of equity securities of the Company or any of its subsidiaries, any
tender offer or exchange  offer that if  consummated  would result in any person
beneficially owning 20% or more of any class of equity securities of the Company
or any of its subsidiaries, or any merger, consolidation,  business combination,
share   exchange,   recapitalization,   liquidation,   dissolution   or  similar
transaction  involving  the Company or any of its  subsidiaries,  other than the
transactions contemplated by the Merger Agreement.

   The Merger  Agreement  provides  that,  except as expressly  permitted by the
terms of the preceding paragraph,  neither the Board of Directors of the Company
nor any committee thereof shall (i) (unless, prior to the acceptance for payment
of shares of Company Common Stock  pursuant to the Offer,  it determines in good
faith, based upon the advice of outside counsel, that it is required to do so in
order to comply with its fiduciary  duties to the Company's  shareholders  under
applicable law) withdraw or modify,  or propose  publicly to withdraw or modify,
in a manner adverse to Crane,  the approval or  recommendation  by such Board of
Directors or such committee of the Offer (including by amendment of the Schedule
14D-9),  the Merger or the Merger  Agreement,  (ii)  approve  or  recommend,  or
propose  publicly to approve or  recommend,  any  Acquisition  Proposal or (iii)
cause the Company to enter into any letter of intent,  agreement  in  principle,
acquisition   agreement  or  other  similar  agreement  (each,  an  "Acquisition
Agreement") related to any Acquisition Proposal.  Notwithstanding the foregoing,
in the event that prior to the acceptance for payment of Shares  pursuant to the
Offer the Company receives a Superior Proposal (as defined below),  the Board of
Directors  of the Company  may,  if it  determines  in good faith,  based on the
advice of outside counsel,  that it is required to do so in order to comply with
its fiduciary  duties to the Company's  shareholders  under  applicable law, (x)
withdraw or modify its approval or  recommendation  of the Offer,  the Merger or
the Merger  Agreement or (y) approve or  recommend  such  Superior  Proposal and
terminate the Merger Agreement (and concurrently with or after such termination,
if it so chooses,  cause the Company to enter into an Acquisition Agreement with
respect  to any  Superior  Proposal)  but only at a time that is after the third
business  day  following  Crane's  receipt of written  notice  from the  Company
advising  Crane  that the Board of  Directors  of the  Company  has  received  a
Superior Proposal, specifying the terms and conditions of such Superior Proposal
and  identifying the person making such Superior  Proposal.  For purposes of the
Merger  Agreement,  a "Superior  Proposal" means any proposal or offer made by a
third party to acquire, directly or indirectly,  for consideration consisting of
cash and/or securities, more than 50% of the combined voting power of the shares
of Company Common Stock then outstanding or a substantial  portion of the assets
of the Company and its  subsidiaries  and  otherwise on terms which the Board of
Directors of the Company  determines in its good faith judgment,  based upon the
advice  of its  financial  advisors,  to be  more  favorable  to  the  Company's
shareholders than the Offer and the Merger and for which financing is either not
a contingency, or, if a contingency, is then committed and available.

   In  addition  to the  obligations  of  the  Company  set  forth  in  the  two
immediately preceding  paragraphs,  the Company is to as promptly as practicable
advise Crane of any Acquisition  Proposal,  the material terms and conditions of
such Acquisition  Proposal and the identity of the person making such request or
Acquisition  Proposal.  The Company will keep Crane  reasonably  informed of the
status and details (including amendments) of any such Acquisition Proposal.

   None of the foregoing  provisions of the Merger  Agreement shall prohibit the
Company from taking and disclosing to its  shareholders a position  contemplated
by  Rule  14e-2(a)  promulgated  under  the  Exchange  Act or  from  making  any
disclosure to the Company's  shareholders  if, in the good faith judgment of the
Board of Directors  of the Company,  after  consultation  with outside  counsel,
failure so to disclose would be  inconsistent  with its fiduciary  duties to the
Company's shareholders under applicable law; provided, however, that neither the
Company nor its Board of Directors nor any committee thereof shall,

                               20
<PAGE>
except as permitted by such provisions,  withdraw or modify, or propose publicly
to withdraw or modify,  its position with respect to this Agreement or the Offer
or the  Merger or  approve  or  recommend,  or  propose  publicly  to approve or
recommend, an Acquisition Proposal.

   Access to Information.  The Merger Agreement provides that, until the earlier
of the  termination of the Merger  Agreement and the Effective Time, the Company
will give Crane and the Purchaser and their  representatives  reasonable access,
during normal  business  hours,  to the offices and other  facilities and to the
books and records of the Company and its subsidiaries.

   Required  Authorizations.  The Merger  Agreement  provides  that  Crane,  the
Purchaser and, subject to the provisions of the Merger Agreement discussed under
the heading "No Solicitation",  above ("Section 5.02"), the Company, shall each,
and subject to Section 5.02,  the Company  shall cause each of its  subsidiaries
to, as promptly as practicable,  take all reasonable actions necessary to obtain
all  Required  Authorizations  (if any)  required to be given or obtained by it,
respectively,  to permit  Crane  and the  Purchaser,  on the one  hand,  and the
Company, on the other, to consummate the transactions contemplated by the Merger
Agreement and the Stock Option Agreement and to realize the respective  benefits
to each party contemplated thereby; provided that Crane shall not be required to
take any action to comply with any legal  requirement or agree to the imposition
of any order of any  Governmental  Authority that would (i) prohibit or restrict
the  ownership or operation by Crane of any portion of the business or assets of
Crane or the  Company  (or any of their  respective  subsidiaries),  (ii) compel
Crane or the Company (or any of their respective  subsidiaries) to dispose of or
hold separate any portion of its or the Company's  business or assets,  or (iii)
impose any  limitation  on the  ability of Crane or the  Company or any of their
respective  affiliates  or  subsidiaries  to own or  operate  the  business  and
operations of the Company and its  subsidiaries,  and provided  further that the
Company  and its  subsidiaries  are not to incur fees and  expenses in excess of
$25,000 in the aggregate in order to obtain certain such Required Authorizations
without the prior written consent of Crane.

   Crane, the Purchaser and,  subject to Section 5.02, the Company,  are to each
cooperate  with the  others  in  filing  in a timely  manner  any  applications,
requests,  reports,   registrations  or  other  documents,   including,  without
limitation,  all  reports  and  documents  required  to be filed by or under the
Exchange Act (including,  without limitation,  the Offer documents, the Schedule
14D-9  and  the  Proxy  Statement),   with  any  Governmental  Authority  having
jurisdiction  with  respect  to the  transactions  contemplated  by  the  Merger
Agreement  and  in  consulting  with  and  seeking  favorable  action  from  any
Governmental Authority.

   Subject  to  Section  5.02,  the  Company  is to, and is to cause each of its
subsidiaries to, take all reasonable action necessary to obtain all approvals or
consents of any person needed in order that certain  contracts  continue in full
force  and  effect  under  the same  terms and  conditions  currently  in effect
following consummation of the transactions contemplated by the Merger Agreement;
provided,  however,  that the  receipt  of any  approval  or  consent  under any
contracts  pursuant  to  the  requirement  stated  in  this  paragraph  is not a
condition  precedent to the  obligations of Crane or Purchaser  under the Merger
Agreement.

   Subject to Section  5.02,  the Company and its Board of Directors  are to (i)
take all reasonable action necessary to ensure that no state takeover statute or
similar  statute or regulation in effect on the date of the Merger  Agreement is
or becomes applicable to the Offer, the Merger, the Merger Agreement,  the Stock
Option Agreement,  the Shareholder  Agreements or any of the other  transactions
contemplated by the Merger Agreement and (ii) if any such state takeover statute
or similar statute or regulation  becomes  applicable to the Offer,  the Merger,
the Merger Agreement,  the Stock Option Agreement, the Shareholder Agreements or
any other transaction contemplated by the Merger Agreement,  take all reasonable
action  necessary  to ensure  that the  Offer,  the  Merger,  the  Stock  Option
Agreement, the Shareholder Agreements and the other transactions contemplated by
the Merger  Agreement may be consummated as promptly as practicable on the terms
contemplated  by the Merger  Agreement  and  otherwise to minimize the effect of
such statute or regulation on the Merger and the other transactions contemplated
by the Merger Agreement.

   Financial  Statements of the Company. As soon as practicable but in any event
within 30 days after the end of each calendar month  commencing  with July 1998,
through  the  consummation  of the Offer or  earlier  termination  of the Merger
Agreement in accordance with its terms, the Company is to deliver to

                               21
<PAGE>
Crane unaudited  consolidated balance sheets of the Company and its subsidiaries
as at the end of such calendar month and as at the end of the comparative  month
of the  preceding  year,  together  with  unaudited  summaries  of  consolidated
earnings of the Company and its  subsidiaries  for such  calendar  month and the
comparative  calendar month of the preceding year. As soon as practicable but in
any event  within 30 days after the end of each fiscal  quarter of the  Company,
commencing  with June 30,  1998,  and within 60 days after the end of the fiscal
year ended  December 31, 1998, as the case may be, through the  consummation  of
the Offer or earlier  termination  of the Merger  Agreement,  the  Company is to
deliver to Crane unaudited  consolidated and consolidating balance sheets of the
Company and its  subsidiaries as at the end of such fiscal quarter and as at the
end of the comparative  fiscal quarter of the preceding year,  together with the
related  unaudited  statements  of  consolidated  income  and cash flows for the
fiscal quarters then ended.

   Employee Matters. The Merger Agreement includes Crane's agreement (a) that on
and  after  the  consummation  of the Offer and until the date that is 18 months
after the Effective Time,  Crane shall cause the Company,  and, on and after the
Effective Time, the Surviving Corporation,  to honor the severance policy of the
Company  and the  employment  agreements  that  are  identified  in the  Company
Disclosure  Schedule,  (b) to give the  employees of the Company full credit for
purposes  of  eligibility  and  vesting  under  any  employee  benefit  plans or
arrangements  maintained  by Crane,  the Company or any  subsidiary of Crane for
such employees'  service with the Company or any of its subsidiaries to the same
extent  recognized by the Company  immediately  prior to the consummation of the
Offer, (c) to waive all limitations as to pre-existing conditions, exclusions or
waiting  periods  with  respect  to  participation  and  coverage   requirements
applicable to the Company  employees  under any welfare  benefit plans that such
employees may be eligible to participate in after the  consummation of the Offer
and (d) to provide employees of the Company,  and, after the Effective Time, the
Surviving  Corporation,  with employee benefits  comparable to those provided by
Crane (or any of its subsidiaries) to similarly  situated employees of Crane (or
any of its subsidiaries).

   Rights Agreement.  The Merger Agreement  provides that the Board of Directors
of the Company will take all further action  reasonably  requested in writing by
Crane (including redeeming the Rights immediately prior to the Effective Time or
amending the Rights Agreement) in order to render the Rights inapplicable to the
Offer,  the  Merger  and  the  other  transactions  contemplated  by the  Merger
Agreement.

   Indemnification;  Directors' and Officers'  Insurance.  The Merger  Agreement
provides  that for six years after the  Effective  Time,  Crane shall,  or shall
cause the Company to, indemnify,  defend and hold harmless any person who is, or
has been at any time prior to the date of the Merger  Agreement,  or who becomes
prior to the Effective Time, a director or an officer (an "Indemnified  Person")
of the Company or any of its subsidiaries against all losses,  claims,  damages,
liabilities,  costs  and  expenses  (including  attorneys'  fees and  expenses),
judgments,  fines,  losses and amounts paid in settlement in connection with any
actual or threatened action,  suit, claim,  proceeding or investigation  (each a
"Claim")  to the  extent  that any such Claim is based on, or arises out of: (i)
the fact that such Indemnified  Person is or was a director or an officer of the
Company or any of its  subsidiaries  or is or was  serving at the request of the
Company  or any of its  subsidiaries  as a  director  or an  officer  of another
corporation,  partnership, joint venture, trust or other enterprise; or (ii) the
Merger Agreement or any of the transactions contemplated hereby, in each case to
the extent that any such Claim pertains to any matter or fact arising,  existing
or occurring prior to or at the Effective Time, regardless of whether such Claim
is asserted or claimed  prior to, at or after the  Effective  Time,  to the full
extent  permitted  under  the  PBCL,  the  Amended  and  Restated   Articles  of
Incorporation of the Company and the Company's By-laws; provided,  however, that
neither  Crane nor the Company  shall be required to indemnify  any  Indemnified
Person in connection  with any  proceeding  (or portion  thereof)  involving any
Claim  initiated  by such  Indemnified  Person  unless  the  initiation  of such
proceeding  (or portion  thereof)  was  authorized  by the Board of Directors of
Crane or unless such  proceeding is brought by an Indemnified  Person to enforce
rights to indemnification under the Merger Agreement.  If any Indemnified Person
becomes involved in any Claim, after the consummation of the Offer, Crane shall,
or shall cause the Company to,  periodically  advance to such Indemnified Person
its  legal and  other  expenses  (including  the cost of any  investigation  and
preparation incurred in connection therewith),  subject to the providing by such
Indemnified Person of an undertaking to reimburse all amounts so advanced in the
case of a final nonappealable determination by a court of competent jurisdiction
that such Indemnified Person is not entitled to be indemnified therefor.

                               22
<PAGE>
   The Merger  Agreement  also provides that Crane or the Company shall maintain
the Company's existing directors' and officers' liability insurance policy ("D&O
Insurance")  for a period of not less than six years after the  Effective  Time;
provided,  however, that Crane may substitute therefor policies of substantially
similar  coverage  (including  pursuant  to  Crane's  own  policy)  and  amounts
containing  terms no less  advantageous  to such former  directors  or officers;
provided  further that,  subject to the preceding  proviso,  if the existing D&O
Insurance  expires or is canceled  during such  period,  Crane or the  Surviving
Corporation  shall use their best  efforts to obtain  substantially  similar D&O
Insurance; and provided further that neither Crane nor the Surviving Corporation
shall be required to pay an annual  premium for D&O  Insurance in excess of 200%
of the last annual premium paid prior to the date of the Merger  Agreement,  but
in such case shall purchase as much coverage as possible for such amount.

   Public Announcement. The Merger Agreement provides that Crane and the Company
will  consult  with each  other  before  issuing,  and  provide  each  other the
opportunity to review,  comment upon and concur with, any press release or other
public  statements with respect to the  transactions  contemplated by the Merger
Agreement,  including  the  Offer and the  Merger,  and shall not issue any such
press  release or make any such  public  statement  prior to such  consultation,
except as may be required by applicable  law,  court  process or by  obligations
pursuant to any listing agreement with any national securities exchange.

   Shareholder Litigation.  The Merger Agreement provides that the Company shall
give Crane the opportunity to participate,  at no expense to the Company, in the
defense or settlement of any shareholder  litigation against the Company and its
directors relating to the transactions  contemplated by the Merger Agreement. No
such settlement is to be agreed to without Crane's consent;  provided,  however,
that if a  failure  to so  consent  is the  sole  cause of the  occurrence  of a
Material Adverse Effect, then such Material Adverse Effect shall not be an Event
for  purposes  of  Section  14 of this  Offer to  Purchase  nor  shall  Crane be
permitted to terminate the Merger Agreement solely due to the occurrence of such
Material Adverse Effect.

   Conditions to Consummation of the Merger.  Pursuant to the Merger  Agreement,
the respective obligations of Crane, the Purchaser and the Company to consummate
the Merger are subject to the satisfaction,  at or before the Effective Time, of
each of the following conditions: (i) the shareholders of the Company shall have
duly approved the transactions contemplated by the Merger Agreement, if required
by applicable law; (ii) any waiting period (and any extension thereof) under the
HSR Act  applicable  to the Merger  shall have expired or  terminated;  (iii) no
judgment,   decree,  statute,  law,  ordinance,   rule,  regulation,   temporary
restraining order,  preliminary or permanent  injunction or other order enacted,
entered, promulgated,  enforced or issued by any court of competent jurisdiction
or  other  Governmental  Authority  or  other  legal  restraint  or  prohibition
preventing the consummation of the Merger shall be in effect; provided, however,
that each of the parties shall have used all  reasonable  efforts to prevent the
entry of any such  restraints  and to appeal as promptly  as  possible  any such
restraints  that may be entered;  and (iv) the Purchaser shall have accepted for
payment and paid for Shares pursuant to the terms and conditions of the Offer.

   Termination. The Merger Agreement may be terminated at any time prior to
the Effective Time, notwithstanding approval thereof by the shareholders of
the Company: (i) by the mutual written consent of Crane and the Company; (ii)
by either Crane or the Company:

     (a) if the Offer is terminated  or withdrawn  pursuant to its terms without
    any Shares being purchased thereunder; provided, however, that neither Crane
    nor the Company may so  terminate  the Merger  Agreement if such party shall
    have materially breached the Merger Agreement;

     (b) if the Offer has not been  consummated on or before October,  31, 1998;
    or

     (c) if any  Governmental  Authority  shall  have  issued an order,  decree,
    ruling  or  injunction  or taken  any other  action  permanently  enjoining,
    restraining  or  otherwise  prohibiting  acceptance  for  payment  of Shares
    pursuant  to the Offer or the  consummation  of the Merger  and such  order,
    decree,  ruling,  injunction  or other  action  shall have become  final and
    nonappealable;

   (iii) by the Company if Crane or the  Purchaser  shall not have  accepted for
payment  and paid for shares of Company  Common  Stock  pursuant to the Offer in
violation of the terms hereof and of the Merger  Agreement;  provided,  however,
that the Company may not so terminate the Merger  Agreement if the Company shall
have materially breached the Merger Agreement;

                               23
<PAGE>
   (iv) by the Company in accordance  with Section 5.02 prior to the  acceptance
for payment of Shares pursuant to the Offer;  provided that it has complied with
all provisions of that Section;

   (v) by Crane prior to the purchase of Shares pursuant to the Offer if (i) the
Board of Directors of the Company or any committee  thereof shall have withdrawn
or modified in a manner adverse to Crane its approval or  recommendation  of the
Offer (including by amendment of the Schedule  14D-9),  the Merger or the Merger
Agreement, or approved or recommended any Superior Proposal or (ii) the Board of
Directors of the Company or any  committee  thereof  shall have resolved to take
any of the foregoing actions; or

   (vi) by Crane or the  Purchaser  pursuant  to  Section  5.01(c) of the Merger
Agreement (regarding advice of certain changes).

   In the event of any such  termination  of the Merger  Agreement by either the
Company or Crane,  the Merger  Agreement shall forthwith become void and have no
effect,  without any liability or obligation on the part of Crane, the Purchaser
or the  Company,  except as to certain  provisions  and to the extent  that such
termination  results from the willful and  material  breach by a party of any of
its representations, warranties, covenants or agreements set forth in the Merger
Agreement.

   The Merger  Agreement  may be amended  by the  parties at any time  before or
after the Company Shareholder Approval;  provided,  however, that after any such
approval,  there shall not be made any  amendment  that by law requires  further
approval by the shareholders of the Company without the further approval of such
shareholders. The Merger Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties.

   At any time prior to the Effective  Time, a party may (a) extend the time for
the  performance  of any of the  obligations or other acts of the other parties,
(b) waive any  inaccuracies in the  representations  and warranties of the other
parties contained in the Merger Agreement or in any document  delivered pursuant
to the Merger Agreement or (c) with certain exceptions,  waive compliance by the
other parties with any of the  agreements or conditions  contained in the Merger
Agreement.  Any agreement on the part of a party to any such extension or waiver
shall be valid only if set forth in an instrument in writing signed on behalf of
such party.  The failure of any party to the Merger  Agreement  to assert any of
its rights under the Merger Agreement or otherwise shall not constitute a waiver
of such rights.

   A termination of the Merger  Agreement,  an amendment of the Merger Agreement
or an extension or waiver by any party to the Merger  Agreement  shall, in order
to be  effective,  require  action by its Board of Directors or, with respect to
any  amendment to the Merger  Agreement,  to the extent  permitted by applicable
law, a duly authorized committee of its Board of Directors.

   Fees and Expenses.  Except as provided below, all fees and expenses  incurred
in  connection  with the  Merger  Agreement  and the  transactions  contemplated
thereby are to be paid by the party incurring such fees or expenses,  whether or
not the Merger is consummated.

   The Company is to  reimburse  Crane for  out-of-pocket  expenses  incurred by
Crane relating to the transactions contemplated by the Merger Agreement prior to
termination  (including,  but not  limited  to,  fees and  expenses  of  Crane's
counsel,  accountants and financial advisors), if (i) the Merger Agreement shall
have  been  terminated  pursuant  to  the  provisions  of the  Merger  Agreement
described in paragraphs (iv) or (v) under the heading  "Termination" above, (ii)
the Company enters into an  Acquisition  Agreement with a party other than Crane
or any of its  affiliates  within one year of the date of such  termination  and
(iii) the transaction  contemplated by such Acquisition Agreement is consummated
within 18 months of the date of such  termination.  Such  reimbursement is to be
paid in same-day  funds within one business  day after the  consummation  of the
transaction contemplated by any such Acquisition Agreement.

   The Stock Option Agreement.  Following is a brief summary of the Stock Option
Agreement,  a copy of which has been filed as an exhibit to the  Schedule  14D-1
filed by the Purchaser  with the Commission in connection  with the Offer.  Such
summary is qualified in its entirety by reference to the Stock Option Agreement.

                               24
<PAGE>
   Pursuant to the Stock Option Agreement,  Crane has the irrevocable right (the
"Stock Option"), under certain circumstances,  to acquire from the Company up to
997,633 shares of Company Common Stock (the "Option  Shares"),  or approximately
19.9%  of the  outstanding  Company  Common  Stock  on the  date  of the  Merger
Agreement,  including the associated  Rights, at a price of $2.75 per share. The
exercise  price is payable in cash.  The Stock Option  Agreement  could have the
effect of making an  acquisition  of the  Company by a third  party more  costly
because of the need to acquire in any such  transaction the Option Shares issued
under the Stock Option Agreement.

   The Stock Option may be exercised by Crane,  in whole or in part, at any time
or from time to time after the termination of the Merger  Agreement  pursuant to
the  provisions of the Merger  Agreement  described in clause (iv) or clause (v)
under the heading  "Termination",  above (an "Exercise Event"). The Stock Option
shall terminate upon the earlier of (i) the consummation of the Offer,  (ii) the
termination  of the  Merger  Agreement  pursuant  to  its  terms  (other  than a
termination  following  an  Exercise  Event),  or (iii) 365 days  following  any
termination of the Merger  Agreement  following an Exercise Event (or, if at the
expiration  of such  365-day  period,  the Stock  Option  cannot be exercised by
reason of any applicable  judgment,  decree,  order, law,  regulation or waiting
period,  15 days after such  impediment  to exercise  shall have been removed or
such waiting period has expired).

   If, at any time during the period after the  occurrence of an Exercise  Event
and before termination of the Stock Option,  Crane sends to the Company a notice
indicating  Crane's election to exercise its rights to receive the cash value of
any Stock  Option,  then the  Company is to pay to Crane,  in  exchange  for the
cancellation of the Stock Option with respect to such number of Option Shares as
Crane specifies in such notice, an amount in cash equal to such number of Option
Shares  multiplied by the difference  between (i) the average  closing price per
share of Company  Common  Stock for the 10 trading days  commencing  on the 12th
trading day immediately  preceding the date of the notice and (ii) the per share
exercise price of the Stock Option.

   In the  event of any  change  in  Company  Common  Stock or in the  number of
outstanding  shares of  Company  Common  Stock by  reason  of a stock  dividend,
split-up,   recapitalization,   combination,   exchange  of  shares  or  similar
transaction  or any other change in the  corporate  or capital  structure of the
Company,  the type and number of shares or securities to be issued upon exercise
of the Stock Option shall be adjusted  appropriately  and proper provision shall
be made in agreements  governing such  transaction,  so that Crane shall receive
upon  exercise  of the  Stock  Option  the  number  and class of shares or other
securities  or property  that Crane would have received in respect of the Option
Shares if the Stock Option had been exercised immediately prior to such event or
the record date therefor.

   The Stock Option Agreement further provides that at any time and from time to
time after  payment for and delivery of the Option  Shares upon  exercise of the
Stock Option,  Crane may make a written request for  registration of all or part
of its  Option  Shares  under  and in  accordance  with  the  provisions  of the
Securities Act of 1933, as amended. Such registration may be, at Crane's option,
a shelf registration or a registration involving an underwritten offering.

   The  Shareholder  Agreements.  Following  is a  summary  of  the  Shareholder
Agreements, the form of which has been filed as an exhibit to the Schedule 14D-1
filed by the Purchaser  with the Commission in connection  with the Offer.  Such
summary is  qualified  in its entirety by reference to the full text of the form
of Shareholder Agreement.

   Pursuant  to the  Shareholder  Agreements,  each of Atalanta  Selective  Fund
Number Six Limited Partnership, Stephen A. Wells Profit Sharing Plan, Stephen A.
Wells,  Wells  Resources,  Inc.,  Dan Kirkland Wells  Foundation,  R. Nim Evatt,
Robert L. Leon, Susan Leon and Roland K. Bullard, II (each, a "Shareholder") has
agreed, among other things, that, (i) until the earlier of the date on which the
Offer is  terminated  or withdrawn or the date on which the Merger  Agreement is
terminated in accordance with its terms,  the Shareholder  will tender,  and not
withdraw,  his Shares  pursuant to the Offer,  and (ii) until the earlier of the
Effective  Time,  the  date on which  the  Merger  Agreement  is  terminated  in
accordance  with its terms or the  purchase  of all of the Shares  owned by such
Shareholder  pursuant  to the  Offer  (the  earliest  of such  dates  being  the
"Expiration Date"), the Shareholder will vote, or grant his consent with respect
to, all of his shares of Company  Common  Stock (x) in favor of the  approval of
the Merger  Agreement and the Merger and any other  transaction  contemplated by
the Merger Agreement or the

                               25
<PAGE>
Stock Option  Agreement,  as such Merger Agreement or Stock Option Agreement may
be modified or amended from time to time,  and (y) against any action,  omission
or  agreement  which  would  impede or  interfere  with,  or have the  effect of
discouraging,   the  Merger,  including,  without  limitation,  any  Acquisition
Proposal other than the Merger.

   At the request of Crane,  each Shareholder  will execute,  in accordance with
the  provisions  of the PBCL,  and  deliver  to Crane an  irrevocable  proxy and
irrevocably  appoint  Crane or its  designees  his attorney and proxy to vote or
give consent  with respect to all of his shares of Company  Common Stock for the
purposes set forth above. Any such proxy will terminate on the Expiration Date.

   Each Shareholder  Agreement  contains the agreement of the Shareholder  that,
among other  things,  he will:  (a) until the date that is six months  after the
Expiration  Date,  not,  and  will  not  agree  to,  sell,   transfer,   pledge,
hypothecate,  encumber, assign, tender or otherwise dispose of any of his shares
of Company Common Stock other than pursuant to the Merger Agreement,  unless and
until  such  transferee  executes  and  delivers  to  Crane  a  joinder  to  the
Shareholder  Agreement  pursuant to which such transferee  shall agree that, for
all purposes of the Shareholder  Agreement,  (i) such transferee shall be deemed
to be the Shareholder thereunder and (ii) all shares of the Company Common Stock
transferred to such transferee  pursuant to this provision shall be deemed to be
"Shares" under the Shareholder Agreement;  (b) other than as contemplated by the
Shareholder  Agreement,  until the  Expiration  Date,  not  grant any  powers of
attorney  or  proxies  or  consents  in  respect of any of his shares of Company
Common  Stock,  deposit any of his shares of Company  Common Stock into a voting
trust,  enter  into a voting  agreement  with  respect  to any of his  shares of
Company  Common Stock or otherwise  restrict the ability of the holder of any of
his shares of Company  Common Stock  freely to exercise  all voting  rights with
respect  thereto;  and (c) until the Expiration  Date, not initiate,  solicit or
encourage, directly or indirectly, any inquiries or the making or implementation
of any Acquisition Proposal or engage in any negotiations concerning, or provide
any  confidential  information  or data to, or have any  discussions  with,  any
person relating to an Acquisition  Proposal,  or otherwise facilitate any effort
or attempt to make or implement an Acquisition Proposal.

   Pursuant to each Shareholder Agreement,  Crane has the irrevocable right (the
"Shareholder  Stock  Option"),  at any time or from time to time if the  Company
enters into an Acquisition Agreement with a party other than Crane or any of its
affiliates  within six months after the  Expiration  Date,  to acquire from each
Shareholder  all or any portion of the shares of Company  Common  Stock owned by
each  Shareholder,  including  the  associated  Rights,  at a price of $3.50 per
share. The exercise price is payable in cash.

   In  the   event   (a)  of  any   stock   dividend,   stock   split,   merger,
recapitalization,  reclassification, combination, exchange of shares or the like
of the capital  stock of the Company  on, or  affecting  the shares to be issued
upon exercise of the Shareholder  Stock Option or (b) that the Shareholder shall
become the beneficial owner of any additional  shares of Company Common Stock or
other  securities  entitling  the holder  thereof to vote or give  consent  with
respect  to the  matters  set  forth in the  Shareholder  Agreement,  then  such
additional  shares of Company  Common  Stock and other  securities  shall become
shares subject to the Shareholder  Stock Option and the terms of the Shareholder
Agreement  shall  otherwise  apply  to the  shares  of  capital  stock  or other
instruments  or documents  held by the  Shareholder  immediately  following  the
effectiveness of the events described in clause (a) or the Shareholder  becoming
the  beneficial  owner thereof as described in clause (b), as though,  in either
case, they were shares subject to the Shareholder Agreement.

   Each Shareholder  Agreement  contains the Shareholder's  representations  and
warranties  relating to, among other  things,  (a) the  execution,  delivery and
enforceability of his Shareholder Agreement,  (b) the ownership of his shares of
Company  Common  Stock,  and (c) the  absence of  encumbrances  on his shares of
Company Common Stock.

   Dissenters'  Rights.  No dissenters'  rights are available in connection with
the Offer. However, if the Merger is consummated,  shareholders who fully comply
with the statutory  dissenters'  procedures  set forth in the PBCL, the relevant
portions of which are attached to this Offer to Purchase as Schedule II, will be
entitled  to  receive  cash for the fair  value of their  Shares  as  determined
pursuant to the procedures

                               26
<PAGE>
presented  by the PBCL.  Merely  voting  against the Merger  Agreement  will not
perfect a shareholders'  dissenters'  rights.  Shareholders  are urged to review
carefully  the  dissenting  shareholders'  rights  provisions  of  the  PBCL,  a
description of which is provided below and the full text of which is attached to
this Offer to  Purchase as Schedule  II and  incorporated  herein by  reference.
SHAREHOLDERS  WHO FAIL TO COMPLY  STRICTLY WITH THE APPLICABLE  PROCEDURES  WILL
FORFEIT THEIR DISSENTERS'  RIGHTS IN CONNECTION WITH THE MERGER. See Schedule II
to this Offer to Purchase.

   Sections 1571 through 1580 of the PBCL  ("Subchapter  D") and Section 1930(a)
of the PBCL,  copies of which are included in Schedule II attached to this Offer
to  Purchase,  entitle any holder of record of Shares who objects to the Merger,
in lieu of receiving the consideration for such Shares provided under the Merger
Agreement,  to demand in  writing  that he be paid in cash the fair value of his
Shares.  Section 1572 of the PBCL  defines  "fair value" as "[t]he fair value of
shares  immediately before the effectuation of the corporate action to which the
dissenter objects,  taking into account all relevant factors,  but excluding any
appreciation or depreciation in anticipation of the corporate action."

   Before the vote of the  shareholders  is taken on the Merger,  the dissenting
shareholder  must deliver to the Company a written notice of intention to demand
that he be paid the fair  value of his Shares if the  Merger is  effected.  Such
written  notice must be sent to the Secretary of the Company at Lee Park,  Suite
6000,  555 North Lane,  Conshohocken,  Pennsylvania  19428.  A vote  against the
Merger is not  sufficient  to satisfy the  requirement  of  delivering a written
notice to the Company.  In addition,  the shareholder must not effect any change
in the  beneficial  ownership  of his Shares  from the date of filing the notice
with the Company through the  consummation  of the Merger,  and Shares for which
payment  of fair  value is  sought  must  not be  voted in favor of the  Merger.
Failure by a dissenting  shareholder  to comply with any of the  foregoing  will
result in his  forfeiture  of any right to demand  payment of fair value for his
Shares.

   A record holder of Shares held in whole or in part for the benefit of another
person  may  assert  dissenters'  rights  as to  fewer  than  all of the  Shares
registered  in his name  only if he  dissents  with  respect  to all the  Shares
beneficially  owned by any one person and  discloses the name and address of the
person or persons on whose behalf he dissents.  A beneficial owner of Shares who
is not the record  holder may assert  dissenters'  rights with respect to Shares
held on his behalf if he  submits  to the  Company  the  written  consent of the
record  holder not later than the time of assertion  of  dissenters'  rights.  A
beneficial  owner may not dissent  with  respect to fewer than all of the Shares
owned by him, whether or not such Shares are registered in his name.

   If the Merger is approved,  the Company shall mail to all dissenters who gave
due notice of their  intention to demand payment of fair value and who refrained
from voting in favor of the Merger, a notice stating where and when a demand for
payment should be sent and  certificates for Shares deposited in order to obtain
payment.  The notice shall be  accompanied  by a copy of Subchapter D and a form
for demanding  payment.  The time set for the receipt of demands and the deposit
of  certificates  shall not be less than 30 days from the mailing of the notice.
Failure by a shareholder to demand payment or deposit  certificates  pursuant to
such  notice  will  cause  such  shareholder  to lose all  right to have a court
determine  the fair value of his  Shares.  If the  Merger has not been  effected
within  60  days  after  the  date  set for  demanding  payment  and  depositing
certificates,   the  Company  shall  return  any  certificates  that  have  been
deposited.  The  Company,  however,  may at any  later  time  send a new  notice
regarding demand for payment and deposit of certificates with like effect.

   Promptly  after the  consummation  of the  Merger or upon  timely  receipt of
demand for payment if the Merger has already been  effected,  the Company  shall
remit to dissenters who have made timely demand and deposited their certificates
the amount the Company  estimates  to be the fair value of their  Shares or give
written  notice that no remittance  will be made under Section 1577 of the PBCL.
Such  remittance or notice shall be accompanied by (i) the closing balance sheet
and statement of income of the Company for a fiscal year ending not more than 16
months  prior to the date of  remittance  or  notice  together  with the  latest
available  interim  financial  statements,  (ii) a  statement  of the  Company's
estimate of the fair value of the Shares, and (iii) a notice of the right of the
dissenting shareholder to demand payment or

                               27
<PAGE>
supplemental payment, as the case may be, accompanied by a copy of Subchapter D.
If the  Company  does not remit the amount of its  estimate of the fair value of
the Shares,  it shall return all  certificates  that have been deposited and may
make a notation thereon that a demand for payment has been made.

   If  Shares  with  respect  to  which  notation  has  been  so made  shall  be
transferred, each new certificate issued therefor shall bear a similar notation,
together  with  the  name of the  original  dissenting  holder  or owner of such
Shares.  A  transferee  of such Shares  shall not acquire by such  transfer  any
rights in the Company  other than those that the  original  dissenter  had after
making demand for payment of fair value for such Shares.

   If a dissenting shareholder believes that the amount estimated or paid by the
Company for his Shares is less than the fair value,  the shareholder may send to
the  Company  his own  estimate of the fair value which shall be deemed a demand
for payment of the amount of the deficiency.  If the dissenter does not file his
own  estimate  of fair value  within 30 days after the mailing by the Company of
its remittance or estimate of fair value,  the dissenter shall be entitled to no
more than the amount remitted to him or estimated by the Company.

   Within 60 days after the latest of (i) the  consummation of the Merger,  (ii)
timely  receipt  of any  demands  for  payment  or (iii)  timely  receipt of any
shareholder  estimates  of  fair  value,  if  any  demands  for  payment  remain
unsettled,  the Company may file in court an application  for relief  requesting
that the fair value of the Shares be  determined  by the court.  Each  dissenter
whose demand has not been settled  shall be made a party to the  proceeding  and
shall be entitled to recover the amount by which the fair value of his Shares is
found to exceed the amount, if any, previously remitted,  plus interest.  If the
Company fails to file an application within the 60-day period, any dissenter who
has not settled  his claim may do so in the name of the  Company  within 30 days
after the expiration of this 60-day period. If no dissenter files an application
within such 30-day period,  each dissenter entitled to file an application shall
be paid no more than the Company's  estimate of the fair value of his Shares and
may bring an action to recover any amount not previously remitted.

   The costs and expenses of any valuation proceedings, including the reasonable
compensation  and expenses of any  appraiser  appointed  by the court,  shall be
determined by the court and assessed against the Company except that any part of
such costs and  expenses  may be  apportioned  and  assessed  as the court deems
appropriate  against all or some of the  dissenters  whose  action in  demanding
supplemental payment is found by the court to be dilatory, obdurate,  arbitrary,
vexatious  or in bad faith.  The court may also assess the fees and  expenses of
counsel and experts for any or all of the dissenters  against the Company if the
Company fails to comply  substantially with Subchapter D or acts in bad faith or
in a dilatory,  obdurate,  arbitrary  or  vexatious  manner.  The court can also
assess any such fees or expenses  incurred by the Company against a dissenter if
such  dissenter is found to have acted in bad faith or in a dilatory,  obdurate,
arbitrary or vexatious  manner.  If the court finds that the services of counsel
for any dissenter were of substantial benefit to the other dissenters and should
not be assessed  against the Company,  it may award to such  counsel  reasonable
fees to be paid out of the amounts awarded to the dissenters who were benefited.

   Section  1712  of  the  PBCL  provides  that  a  director  of a  Pennsylvania
corporation  stands in a fiduciary relation to such corporation and must perform
his duties as a director in good faith, in a manner he reasonably believes to be
in  the  best  interests  of the  corporation  and  with  such  care,  including
reasonable inquiry, skill and diligence,  as a person of ordinary prudence would
use under similar circumstances.  Section 1105 of the PBCL provides in substance
that a shareholder  of a  Pennsylvania  corporation  shall not have any right to
obtain, in the absence of fraud or fundamental unfairness, an injunction against
the  Merger,  nor any right to claim the right to  valuation  and payment of the
fair value of his Shares  because of the Merger,  except that he may dissent and
claim such  payment if and to the extent  provided in  Subchapter D of the PBCL,
described above. Absent fraud or fundamental unfairness, such dissenters' rights
are the exclusive remedy of such shareholders.  However, the United States Court
of Appeals, Third Circuit,  interpreting the predecessor statute to Section 1105
of the PBCL in Herskowitz  v.  NutriSystem,  Inc.,  concluded  that  dissenters'
rights  coexist with common law causes of action,  such as  rescission  or money
damages,  in  the  context  of  an  action  for  breach  of  fiduciary  duty  or
misrepresentation in a cash-out

                               28
<PAGE>
merger.  Shareholders  should be aware that due to the  enactment of the PBCL in
1988 it is unclear  whether the decision in  Herskowitz  remains  applicable  to
dissenters'  rights.  IN  VIEW  OF  THE  COMPLEXITIES  OF  THESE  PROVISIONS  OF
PENNSYLVANIA  LAW,  SHAREHOLDERS WHO ARE CONSIDERING  DISSENTING FROM THE MERGER
SHOULD CONSULT THEIR OWN LEGAL COUNSEL.

   SEE  SCHEDULE  II  ATTACHED  HERETO  FOR A  REPRODUCTION  OF THE  TEXT OF THE
RELEVANT SECTIONS OF THE PBCL.

   Plans for the Company.  If Crane acquires  control of the Company,  its first
priority will be to restore  profitability to the Company. The Company's product
lines share  common  technologies  and  customers  with two of Crane's  business
units--Crane Nuclear and Dynalco  Controls--and the integration of the Company's
operations  into these two businesses  could offer  significant  synergies.  The
RADView business of the Company does not align with any current Crane operation,
however,  and Crane will be evaluating that business and the available strategic
alternatives for it. Crane intends to continue its review of the Company and its
subsidiaries  and their  respective  assets,  businesses,  corporate  structure,
capitalization,  operations,  properties, policies, management and personnel. If
Crane  acquires  control of the Company,  Crane will  determine  what actions or
changes,  if any,  would be desirable in light of the  circumstances  which then
exist,  and  reserves  the right to effect  such  actions  or  changes.  Crane's
decisions  could be  affected  by  information  hereafter  obtained,  changes in
general  economic or market  conditions or in the business of the Company or its
subsidiaries, actions by the Company or its subsidiaries and other factors.

   Except as described in this Offer to Purchase,  none of the Purchaser,  Crane
nor, to the best knowledge of the Purchaser and Crane, any of the persons listed
on Schedule I, has any present plans or proposals  that would relate to or would
result  in  (i)  an  extraordinary  corporate  transaction,  such  as a  merger,
reorganization or liquidation, involving the Company or any of its subsidiaries,
(ii) a sale or transfer of a material  amount of assets of the Company or any of
its subsidiaries, (iii) any change in the present Company Board or management of
the Company, (iv) any material change in the present  capitalization or dividend
policy  of the  Company,  (v) any  material  change in the  Company's  corporate
structure or business,  (vi) causing a class of  securities of the Company to be
delisted from a national  securities exchange or to cease to be authorized to be
quoted in an inter-dealer  quotation system of a registered  national securities
association  or (vii) a class  of  equity  securities  of the  Company  becoming
eligible for  termination of  registration  pursuant to Section 12(g) (4) of the
Exchange Act.

   The Rights.  The following  discussion is derived from the description of the
Rights  Agreement and the Rights included as part of an exhibit to the Company's
Current  Report  on Form 8-K  dated  October  6,  1997 and is  qualified  in its
entirety by reference to such exhibit.

   Under the Rights Agreement,  each Share carries with it one Right. Each Right
entitles the registered holder to purchase from the Company a unit consisting of
one  one-thousandth  of a share (a  "Unit")  of  Series  A Junior  Participating
Preferred  Stock of the Company at a purchase price of $48.00 per Unit,  subject
to adjustment.

   The Rights Agreement  provides that the Rights will separate from the Company
Common Stock and the "Distribution  Date" will occur (i) upon the earlier of (x)
10 business days following a public  announcement (the date of such announcement
being the "Stock  Acquisition  Date")  that a person or group of  affiliated  or
associated persons (other than the Company, any subsidiary of the Company or any
employee benefit plan of the Company or such subsidiary) (an "Acquiring Person")
has acquired,  obtained the right to acquire,  or otherwise obtained  beneficial
ownership of 15% or more of the then outstanding shares of Company Common Stock,
and (y) 10  business  days  following  the  commencement  of a  tender  offer or
exchange  offer that would result in an Acquiring  Person  owning 15% or more of
the then outstanding  shares of Company Common Stock, or (ii) such later date as
may be  determined  by action of a majority  of the  independent  members of the
Board of  Directors  (such  determination  to be made  prior to such time as any
person  becomes an Acquiring  Person  pursuant to (x) or (y) above).  The Rights
Agreement  exempts  from its  definition  of  Acquiring  Person any person  that
acquires,  obtains  the  right  to  acquire,  or  otherwise  obtains  beneficial
ownership of 15% or more of the then outstanding  shares of Company Common Stock
without any intention of changing or influencing control of the Company

                               29
<PAGE>
provided that such person, as promptly as practicable, divests himself or itself
of a  sufficient  number of shares of Company  Common  Stock so that such person
would no longer  own 15% or more of the  outstanding  shares of  Company  Common
Stock.  Until the Distribution Date, (i) the Rights will be evidenced by Company
Common Stock  certificates,  (ii) new Company Common Stock  certificates  issued
after the Record Date (also  including  shares  distributed  from the  Company's
treasury)  will  contain  a  notation  incorporating  the  Rights  Agreement  by
reference and (iii) the surrender for transfer of any certificates  representing
outstanding Company Common Stock will also constitute the transfer of the Rights
associated with the Company Common Stock represented by such certificates.

   The Rights are not exercisable until the Distribution Date and will expire at
the close of business on the tenth  anniversary of the Rights  Agreement  unless
earlier redeemed by the Company as described below.

   As soon as practicable after the Distribution Date, Rights  Certificates will
be  mailed to  holders  of record  of  Company  Common  Stock as of the close of
business  on  the  Distribution  Date  and,  thereafter,   the  separate  Rights
Certificates alone will represent the Rights.

   In the event that (i) the Company is the  surviving  corporation  in a merger
with an  Acquiring  Person and  shares of  Company  Common  Stock  shall  remain
outstanding,  (ii) a Person becomes the  beneficial  owner of 15% or more of the
then  outstanding  shares of Company  Common  Stock,  (iii) an Acquiring  Person
engages in one or more  "self-dealing"  transactions  as set forth in the Rights
Agreement,  or (iv) during such times as there is an Acquiring  Person, an event
occurs  which  results  in such  Acquiring  Person's  ownership  interest  being
increased  by  more  than 1%  (e.g.,  by  means  of a  reverse  stock  split  or
recapitalization),  then,  in each  such  case,  each  holder  of a  Right  will
thereafter  have the right to  receive  upon  exercise  Units  (or,  in  certain
circumstances,  Company Common Stock, cash,  property or other securities of the
Company)  having a current market value equal to two times the exercise price of
the Right.  The exercise price is the purchase price multiplied by the number of
Units  issuable upon  exercise of a Right prior to the events  described in this
paragraph. Notwithstanding any of the foregoing, following the occurrence of any
of the  events  set forth in this  paragraph,  all  Rights  that are,  or (under
certain  circumstances  specified in the Rights  Agreement)  were,  beneficially
owned by any Acquiring Person will be null and void.

   In the event that, at any time following the Stock  Acquisition Date, (i) the
Company is acquired in a merger or other business  combination  transaction  and
the Company is not the surviving  corporation  (other than a merger described in
the  preceding  paragraph),  (ii) any  person  consolidates  or merges  with the
Company and all or part of the Company  Common  Stock is  converted or exchanged
for securities, cash or property of any other Person or (iii) 50% or more of the
Company's assets or earning power is sold or transferred, each holder of a Right
(except  Rights  which  previously  have been voided as  described  above) shall
thereafter  have the  right  to  receive,  upon  exercise,  common  stock of the
Acquiring  Person having a current  market value equal to two times the exercise
price of the Right.

   The  Rights  Agreement  exempts  certain  shareholders  from  triggering  the
distribution  of the Rights  ("Exempt  Person")  unless  they,  individually  or
together  with  their  affiliates  or  associates,   increase  their  beneficial
ownership of outstanding  Company Common Stock.  These  shareholders  consist of
Edison Venture Fund,  L.P.,  and their  affiliates  and  associates.  The Rights
Agreement  also  designates L. Mark Newman,  Larry D.  Hornbeck,  Don V. Ingram,
Stephen F. Smith, Stephen A. Wells, Walter Epstein, Energy Consolidation,  Inc.,
Atalanta  Investment  Company  and  Atalanta  Selective  Fund Number Six Limited
Partnership as Exempt Persons, so long as those parties and their affiliates and
associates are in compliance with the Standstill  Agreement  between the Company
and certain of the  aforementioned  individuals  and  entities  dated August 18,
1997.

   At any time until (i) ten business days following the Stock  Acquisition Date
or (ii) such later date as a majority of the independent members of the Board of
Directors  shall  determine  (such  determination  to be made  prior to the date
specified in (i) above), a majority of the independent  directors may redeem the
Rights in whole,  but not in part,  at a price of $.001  per Right  (subject  to
adjustment in certain events) (the "Redemption Price"), payable, at the election
of such  majority  of the  independent  directors  in cash or shares of  Company
Common  Stock.  Immediately  upon the  action of a majority  of the  independent
directors  ordering the redemption of the Rights,  the Rights will terminate and
the only right of the holders of Rights will be to receive the Redemption Price.

                               30
<PAGE>
   Until a Right is exercised,  the holder thereof, as such, will have no rights
as a shareholder of the Company,  including,  without  limitation,  the right to
vote or to receive  dividends.  While the distribution of the Rights will not be
taxable to shareholders or to the Company,  shareholders may, depending upon the
circumstances,  recognize  taxable  income in the event that the  Rights  become
exercisable for Units of Preferred Stock (or other consideration).

   Any of the  provisions  of the Rights  Agreement  may be amended  without the
approval  of the  holders  of  Company  Common  Stock at any  time  prior to the
Distribution  Date.  After the  Distribution  Date, the provisions of the Rights
Agreement   may  be  amended  in  order  to  cure  any   ambiguity,   defect  or
inconsistency,  to make changes which do not  adversely  affect the interests of
holders of Rights  (excluding  the  interests of any  Acquiring  Person),  or to
shorten  or  lengthen  any time  period  under the Rights  Agreement;  provided,
however,  that no amendment to adjust the time period governing redemption shall
be made at such time as the Rights are not redeemable.

   On August 10, 1998,  the Company Board  approved (and on August 11, 1998, the
Company  executed)  an  amendment  to  the  Rights  Agreement  to  provide  that
notwithstanding  anything contained in the Rights Agreement to the contrary, (x)
until the  termination  of the Merger  Agreement in  accordance  with its terms,
Crane  (including  each  affiliate  and  associate  of Crane) shall be an Exempt
Person, and (y) no Distribution Date, Stock Acquisition Date or Triggering Event
(as defined in the Rights  Agreement)  will be deemed to have occurred,  neither
Crane nor any  affiliate  or associate of Crane will be deemed to have become an
Acquiring Person and no holder of Rights will be entitled to exercise any Rights
under or be entitled to any rights pursuant to the Rights Agreement by reason of
(i) the approval,  execution, delivery or effectiveness of the Merger Agreement,
the  Stock  Option  Agreement  or  the  Shareholder  Agreements,   or  (ii)  the
consummation  of any of the  transactions  contemplated  by any of the foregoing
agreements  or the  taking of any  action  by any party to any of the  foregoing
agreements or any affiliate or associate  thereof to facilitate the consummation
of any such  transactions.  The Rights Agreement was also amended to (i) provide
that the Rights  Agreement  shall not be amended or  supplemented  in any manner
until the  termination  of the Merger  Agreement  in  accordance  with its terms
without  the prior  written  consent of Crane and (ii) to change the  Expiration
Date of the  Rights  Agreement  to the  earlier  to  occur  of (x) the  close of
business on the tenth  anniversary of the Rights Agreement and (y) the Effective
Time.

   Based on publicly available  information,  the Purchaser believes that, as of
the date of this Offer,  the Rights were not  exercisable,  Rights  Certificates
have not been issued and the Rights were evidenced by the Share Certificates.

   The foregoing summary of the Rights Agreement does not purport to be complete
and is  qualified  in its  entirety  by  reference  to the  text  of the  Rights
Agreement filed as an exhibit to the Company's  Current Report on Form 8-K dated
October 6, 1997 filed with the Commission  and any subsequent  amendments to the
Rights Agreement as filed with the Commission.  Copies of these documents may be
obtained in the manner set forth in Section 8, above.

   Shareholders  are  required  to tender one Right for each Share  tendered  in
order to effect a valid tender of such Share. If the Distribution  Date does not
occur  prior to the  Expiration  Date,  a tender  of Shares  will  automatically
constitute a tender of the associated Rights. See Section 1.

12. SOURCE AND AMOUNT OF FUNDS

   The total amount of funds  required by Purchaser to consummate  the Offer and
the Merger and to pay related fees and expenses is estimated to be approximately
$19,000,000.  Crane will  ensure  that the  Purchaser  has  sufficient  funds to
acquire all the outstanding  Shares pursuant to the Offer and the Merger.  Crane
plans to provide such funds from its cash accounts.

13. DIVIDENDS AND DISTRIBUTIONS

   If, on or after the date of this Offer to  Purchase,  the Company  should (i)
split, combine or otherwise change the Shares or its capitalization,  (ii) issue
or sell any additional  securities of the Company or otherwise cause an increase
in the number of outstanding securities of the Company or (iii) acquire

                               31
<PAGE>
currently  outstanding  Shares or  otherwise  cause a reduction in the number of
outstanding  Shares,  then,  without  prejudice to the Purchaser's  rights under
Sections  1 and 14,  the  Purchaser,  in its  sole  discretion,  may  make  such
adjustments as it deems appropriate in the purchase price and other terms of the
Offer, including,  without limitation, the amount and type of securities offered
to be purchased.

   If,  on or after  the date of this  Offer to  Purchase,  the  Company  should
declare or pay any dividend on the Shares or make any  distribution  (including,
without  limitation,  the  issuance  of  additional  Shares  pursuant to a stock
dividend or stock  split,  the issuance of other  securities  or the issuance of
rights for the  purchase of any  securities)  with respect to the Shares that is
payable  or  distributable  to  shareholders  of record  on a date  prior to the
transfer  to the name of the  Purchaser  or its  nominee  or  transferee  on the
Company's stock transfer records of the Shares purchased  pursuant to the Offer,
then,  without prejudice to the Purchaser's  rights under Sections 1 and 14, (i)
the Per Share  Amount  payable by the  Purchaser  pursuant  to the Offer will be
reduced by the amount of any such cash dividend or cash  distribution,  and (ii)
any  such  non-cash  dividend,  distribution  or  right  to be  received  by the
tendering  shareholders will be received and held by such tendering shareholders
for the account of the  Purchaser  and will be required to be promptly  remitted
and  transferred  by each such  tendering  shareholder to the Depositary for the
account of the Purchaser,  accompanied by appropriate documentation of transfer.
Pending such  remittance  and subject to applicable  law, the Purchaser  will be
entitled to all rights and  privileges as owner of any such  non-cash  dividend,
distribution  or right and may withhold the entire purchase price or deduct from
the purchase price the amount of value  thereof,  as determined by the Purchaser
in its sole discretion.

14. CERTAIN CONDITIONS OF THE OFFER

   Notwithstanding any other provisions of the Offer, the Purchaser shall not be
required  to  accept  for  payment  or,  subject  to any  applicable  rules  and
regulations of the  Commission,  including Rule 14e-1(c)  promulgated  under the
Exchange Act, pay for any tendered  Shares and may terminate or,  subject to the

validly tendered and not properly withdrawn prior to the Expiration Date for the
Offer that number of Shares  which  satisfies  the Minimum  Condition,  (ii) any
applicable  waiting period (and any extensions  thereof) under the HSR Act shall

    contemplated  by the Merger  Agreement or seeking to obtain from the Company

    subsidiaries  taken  as a whole  or Crane  and its  subsidiaries  taken as a
    whole,  as  applicable,  (ii) seeking to prohibit or limit the  ownership or

    any of their  respective  subsidiaries to dispose of or hold separate all or

    of their  respective  subsidiaries,  as a result of the Offer, the Merger or
    any of the other  transactions  contemplated by the Merger Agreement,  (iii)

    of its subsidiaries from effectively controlling in any material respect the
    business  or  operations  of the  Company or its  subsidiaries  or (v) which
    otherwise would  reasonably be expected to have a Material Adverse Effect on
    the Company or Crane; or

     (b) there shall be pending or  threatened  any action or  proceeding by any
    Governmental  Authority  seeking,  or that is  reasonably  likely to result,
    directly or indirectly,  in, any of the consequences  referred to in clauses
    (i) through (v) of paragraph (a) above or by any third party for which there
    is a substantial likelihood of resulting in any of the consequences referred

                               32
<PAGE>
     (c) there shall have occurred any Material  Adverse  Effect with respect to
    the Company and its subsidiaries taken as a whole; or

     (d) (i) the Board of  Directors  of the  Company or any  committee  thereof

    recommendation  of the  Offer  or  the  Merger  Agreement,  or  approved  or
    recommended any Superior Proposal,  (ii) the Company shall have entered into
    an  Acquisition  Agreement  with a  party  other  than  Crane  on any of its

     (e) the Company and the Purchaser and Crane shall have reached an agreement
    that  the  Offer  or the  Merger  Agreement  be  terminated,  or the  Merger
    Agreement shall have been terminated in accordance with its terms; or

     (f) the  representations  and  warranties  of the  Company set forth in the
    Merger  Agreement  shall  not be true and  correct  (without  regard  to any
    materiality   qualifications   or  references  to  Material  Adverse  Effect
    contained  in  any  specific   representation  or  warranty),   as  if  such
    representations  and warranties were made at the time of such  determination
    except to the extent such representations and warranties expressly relate to
    an  earlier  date  (in  which  case as of such  date);  provided  that  this
    paragraph  (f) shall be deemed  satisfied so long as the failure of all such
    representations  and  warranties to be true and correct would not (i) have a
    Material Adverse Effect on the Company, (ii) prevent or materially delay the
    consummation of the Offer,  (iii) materially  increase the cost of the Offer
    to the Purchaser or (iv) have a material  adverse  effect on the benefits to

    respect  to any of the  foregoing  in  effect  on  the  date  of the  Merger
    Agreement, a material worsening or acceleration thereof.

   The foregoing  conditions  (including those set forth in clauses (i) and (ii)
of the initial paragraph) are for the benefit of Crane and the Purchaser and may
be asserted by Crane or the  Purchaser  regardless of the  circumstances  giving
rise to any such conditions and may be waived by Crane or the Purchaser in whole
or in part at any time and from time to time in their reasonable discretion,  in
each case, subject to the terms of the Merger Agreement. The failure by Crane or
the Purchaser at any time to exercise any of the  foregoing  rights shall not be
deemed a waiver of any such right and each such right shall be deemed an ongoing
right which may be asserted at any time and from time to time.

15. CERTAIN LEGAL MATTERS; REQUIRED REGULATORY APPROVALS

   General.  Except as set forth below, neither the Purchaser nor Crane is aware
of any  licenses or other  regulatory  permits that appear to be material to the
business of the Company and its  subsidiaries,  taken as a whole,  that might be
adversely  affected by the  Purchaser's  acquisition of Shares (and the indirect
acquisition of the stock of the Company's  subsidiaries) as contemplated herein,
or of any  filings,  approvals or other  actions by or with any  domestic  (U.S.
federal  or  state),   foreign  or  supranational   governmental   authority  or
administrative  or  regulatory  agency  that  would  be  required  prior  to the
acquisition of Shares (or the indirect acquisition of the stock of the Company's
subsidiaries)  by the Purchaser  pursuant to the Offer as  contemplated  herein.
Should any such  approval or other  action be  required,  it is the  Purchaser's
present intention to seek such approval or action.  However,  the Purchaser does
not presently  intend to delay the purchase of Shares  tendered  pursuant to the
Offer  pending the receipt of any such approval or the taking of any such action
(subject to the Purchaser's right to delay or

                               33
<PAGE>
decline to purchase Shares if any of the conditions in Section 14 shall not have
been  satisfied).  There can be no  assurance  that any such  approval  or other
action,  if needed,  would be obtained  without  substantial  conditions or that
adverse  consequences might not result to the business of the Company,  Crane or
the Purchaser or that certain parts of the  businesses of the Company,  Crane or
the  Purchaser  might  not  have to be  disposed  of or held  separate  or other
substantial  conditions  complied with in order to obtain such approval or other
action or in the event that such  approval was not obtained or such other action
was not taken,  any of which could cause the Purchaser to elect to terminate the
Offer without the purchase of the Shares hereunder.  The Purchaser's  obligation
under the Offer to accept for  payment  and pay for Shares is subject to certain
conditions, including conditions relating to the legal matters discussed in this
Section 15. See Section 14.

   State Takeover  Statutes.  Various  states  throughout the United States have
enacted takeover statutes that purport,  in varying degrees, to be applicable to
attempts to acquire  securities of  corporations  that are  incorporated or have
assets, shareholders, executive offices or places of business in such states. In
Edgar  v.Mite  Corp.,  the  Supreme  Court of the  United  States  held that the
Illinois  Business  Takeover Act, which involved state securities laws that made
the  takeover of certain  corporations  more  difficult,  imposed a  substantial
burden on interstate commerce and therefore was  unconstitutional.  In CTS Corp.
v. Dynamics  Corp. of America,  however,  the Supreme Court of the United States
held that a state may, as a matter of corporate  law and, in  particular,  those
laws concerning corporate  governance,  constitutionally  disqualify a potential
acquiror  from  voting on the  affairs  of a target  corporation  without  prior
approval of the remaining shareholders,  provided that such laws were applicable
only under certain conditions.

   The  Pennsylvania  Takeover  Disclosure Law (the "PTDL") purports to regulate
certain attempts to acquire a corporation  which (1) is organized under the laws
of  Pennsylvania  or (2) has its  principal  place of business  and  substantial
assets located in Pennsylvania.  The PTDL requires, among other things, that the
offeror, 20 days prior to any takeover offer, file a registration  statement for
the takeover  offer with the  Pennsylvania  Securities  Commission  and publicly
disclose the offering price of the proposed offer. However, in Crane Co. v. Lam,
509 F.Supp. 782 (E.D. Pa. 1981), the District Court preliminarily  enjoined,  on
grounds  arising under the United States  Constitution,  enforcement of at least
the portion of the PTDL involving the pre-offer waiting period thereunder.

   Chapter  25 of the PBCL  contains  other  provisions  relating  generally  to
takeovers and acquisitions of certain publicly owned  Pennsylvania  corporations
such as the  Company  that have a class or series  of  shares  entitled  to vote
generally  in the  election of  directors  registered  under the Exchange Act (a
"registered  corporation").  The  following  discussion  is a general and highly
abbreviated  summary of certain features of such chapter,  is not intended to be
complete  or  to  completely  address  potentially   applicable   exceptions  or
exemptions,  and is  qualified  in its entirety by reference to the full text of
Chapter 25 of the PBCL.

   In addition to other  provisions  not  applicable to the Offer or the Merger,
Subchapter  D of Chapter 25 of the PBCL  ("Subchapter  D")  includes  provisions
requiring  approval of a merger of a registered  corporation with an "interested
shareholder" by the  affirmative  vote of the  shareholders  entitled to cast at
least a majority of the votes that all  shareholders  other than the  interested
shareholder  are  entitled  to cast  with  respect  to the  transaction  without
counting the votes of the interested shareholder. This disinterested shareholder
approval  requirement is not applicable to a transaction  (i) approved by a vote
of the board of  directors,  without  counting  the votes of  directors  who are
directors  or  officers  of, or who have a  material  equity  interest  in,  the
interested  shareholder,  (ii) in which  the  consideration  to be  received  by
shareholders  is not  less  than  the  highest  amount  paid  by the  interested
shareholder in acquiring his shares,  or (iii) effected  without  submitting the
proposed merger to a vote of shareholders as permitted in Section 1924(b)(1)(ii)
of the  PBCL.  The  requirements  of  Subchapter  D do not  apply to the  Merger
because,  among other things, the Offer and the Merger have been approved by the
Board of Directors of the Company.

   Subchapter E of Chapter 25 of the PBCL  ("Subchapter E"), among other things,
governs "control  transactions"  (defined  generally as a transaction in which a
person  acquires at least 20% of the voting power of a  corporation  involving a
"registered corporation" and provides that the shareholders of such

                               34
<PAGE>
corporation  are  entitled  to demand  that they be paid the fair value of their
shares. Pursuant to Subchapter E, the minimum value the shareholders can receive
may not be less than the  highest  price  paid per share by the  control  person
within  the  90-day  period  ending  on and  including  the date of the  control
transaction.  The Amended and Restated  Articles of  Incorporation  specifically
provide that Subchapter E does not apply to the Company.

   Subchapter F purports to prohibit under certain  circumstances  a "registered
corporation"  from  engaging in a  "Business  Combination"  with an  "Interested
Shareholder" for a period of five years following the date such person became an
"Interested  Shareholder"  unless:  (i) before such person  became an Interested
Shareholder,  the board of  directors  of the  corporation  approved  either the
Business  Combination or the  transaction  in which the  Interested  Shareholder
became an Interested Shareholder; (ii) the Business Combination is approved by a
majority vote of the corporation's  voting shares, other than shares held by the
Interested  Shareholder,  no earlier  than  three  months  after the  Interested
Shareholder  became,  and provided that at the time of such vote the  Interested
Shareholder is, the beneficial  owner of shares entitled to cast at least 80% of
the votes that all  shareholders  would be  entitled  to cast in an  election of
directors of the corporation,  and the Business Combination  satisfies the "fair
price" criteria  (generally,  the higher of (a) the highest price per share paid
by the Interested  Shareholder at a time when the Interested Shareholder was the
beneficial  owner of a least five percent of the voting power of the corporation
and (b) the market value per share on the announcement  date with respect to the
Business  Combination  or on  the  Interested  Shareholder's  acquisition  date,
whichever  is  higher,  plus,  in any case,  interest  and less the value of any
distributions on the shares);  (iii) the Business Combination is approved by all
of the holders of the corporation's outstanding common shares; (iv) the Business
Combination is approved by a majority vote of the  corporation's  voting shares,
other than shares held by the Interested Shareholder, no earlier than five years
after the Interested  Shareholder became an Interested  Shareholder;  or (v) the
Business  Combination is approved by a majority vote of the corporation's voting
shares no earlier  than five years after the  Interested  Shareholder  became an
Interested  Shareholder and the Business Combination  satisfies the "fair price"
criteria  described  above.  Subchapter F does not apply to the Merger  because,
among other  things,  the Board of  Directors  of the Company has  approved  the
Merger.

   Subchapter  G of  Chapter  25 of  the  PBCL  ("Subchapter  G"),  relating  to
"control-share  acquisitions," prevents under certain circumstances the owner of
a  control-share  block of shares of a registered  corporation  from voting such
shares  unless a majority  of the  "disinterested"  shares  approve  such voting
rights.  Failure to obtain  such  approval  may  result in a forced  sale by the
control-share  owner of the control-share block to the corporation at a possible
loss. The Amended and Restated  Articles of Incorporation  specifically  provide
that Subchapter G does not apply to the Company.

   Subchapter  H of  Chapter  25 of  the  PBCL  ("Subchapter  H"),  relating  to
disgorgement by certain  controlling  shareholders of a registered  corporation,
provides that under certain  circumstances  any profit realized by a controlling
person  from  the  disposition  of  shares  of the  corporation  to  any  person
(including  to  the  corporation  under  Subchapter  G  or  otherwise)  will  be
recoverable  by  the   corporation.   The  Amended  and  Restated   Articles  of
Incorporation  specifically  provide  that  Subchapter  H does not  apply to the
Company.

   Subchapter I of Chapter 25 of the PBCL  ("Subchapter  I") entitles  "eligible
employees"  of a  registered  corporation  to a lump sum  payment  of  severance
compensation  under certain  circumstances if the employee is terminated,  other
than for  willful  misconduct,  within two years after  voting  rights lost as a
result of a control-share  acquisition  are restored by a vote of  disinterested
shareholders  ("Control-Share  Approval") or, in the event the  termination  was
accomplished  pursuant to an agreement,  arrangement or  understanding  with the
acquiring person, within 90 days prior to Control-Share  Approval.  Subchapter J
of  Chapter  25  of  the  PBCL  ("Subchapter  J")  provides  protection  against
termination  or  impairment  under  certain   circumstances  of  "covered  labor
contracts" of a registered  corporation as a result of a "business  combination"
transaction  if the  business  operation  to which the  covered  labor  contract
relates was owned by the  registered  corporation  at the time voting rights are
restored by shareholder  vote after a control-share  acquisition.  Subchapters I
and J apply  only in the event of a  "control-share  acquisition"  specified  in
Subchapter G. The Amended and Restated  Articles of  Incorporation  specifically
provide that Subchapter G does not apply to the Company.

                               35
<PAGE>
   Section 2504 of the PBCL provides that the applicability of Chapter 25 of the
PBCL to a registered  corporation having a class or series of shares entitled to
vote generally in the election of directors registered under the Exchange Act or
otherwise  satisfying the definition of a registered  corporation  under Section
2502(l) of the PBCL shall  terminate  immediately  upon the  termination  of the
status of the corporation as a registered corporation. Purchaser intends to seek
to cause the  Company to  terminate  the  registration  of the Shares  under the
Exchange Act as soon after  consummation of the Merger as the  requirements  for
termination of registration of the Shares are met.

   A number of other  states have  adopted laws and  regulations  applicable  to
attempts to acquire securities of corporations  which are incorporated,  or have
substantial  assets,  shareholders,  principal  executive  offices or  principal
places of business,  or whose business  operations  otherwise  have  substantial
economic  effects,  in such states.  Neither  Purchaser  nor Crane has currently
complied with any state takeover statute or regulation.  Purchaser  reserves the
right to challenge the  applicability  or validity of any state law  purportedly
applicable  to the Offer or the Merger and  nothing in this Offer to Purchase or
any action  taken in  connection  with the Offer or the Merger is  intended as a
waiver of such  right.  If it is  asserted  that any state  takeover  statute is
applicable  to the  Offer  or the  Merger  and an  appropriate  court  does  not
determine  that it is  inapplicable  or  invalid  as applied to the Offer or the
Merger,  Purchaser  might be required to file certain  information  with,  or to
receive approvals from, the relevant state  authorities,  and Purchaser might be
unable to accept for payment or pay for Shares  tendered  pursuant to the Offer,
or be delayed in consummating the Offer or the Merger.  In such case,  Purchaser
may not be  obligated  to accept  for  payment  or pay for any  Shares  tendered
pursuant to the Offer.

   Should any person seek to apply any state  takeover law,  Purchaser will take
such  action as then  appears  desirable,  which  may  include  challenging  the
validity or applicability of any such statute in appropriate court  proceedings.
In the event it is asserted that one or more state takeover laws are applicable,
and an appropriate  court does not determine that such law is, or such laws are,
inapplicable  or invalid as applied to the Offer or Merger,  Purchaser  might be
required to file  certain  information  with,  or receive  approvals  from,  the
relevant state authorities. In addition, if enjoined,  Purchaser might be unable
to accept for payment any Shares  tendered  pursuant to the Offer, or be delayed
in  consummating  the Offer.  In such case,  Purchaser  may not be  obligated to
accept for payment any Shares tendered.

   The Company, directly or through subsidiaries,  conducts business in a number
of states throughout the United States, some of which have enacted takeover laws
as  described  above.  The  Purchaser  does not believe  that any such  takeover
statutes  are  applicable  to the Offer or the Merger and has not  attempted  to
comply  with any such state  takeover  statutes  in  connection  therewith.  The
Purchaser  reserves the right to challenge the validity or  applicability of any
state law  allegedly  applicable  to the Offer or the Merger and nothing in this
Offer to Purchase nor any action taken in  connection  herewith is intended as a
waiver of that right.

   Antitrust.  Under  the HSR  Act and the  rules  that  have  been  promulgated
thereunder,  certain  acquisition  transactions  may not be  consummated  unless
certain information has been furnished to the Antitrust Division and the Federal
Trade Commission (the "FTC") and certain waiting period  requirements  have been
satisfied.  The  acquisition of Shares  pursuant to the Offer is subject to such
requirements. See the Introduction and Section 14.

   Crane  expects  to file on August  17,  1998  with the FTC and the  Antitrust
Division  a  Premerger  Notification  and  Report  Form in  connection  with the
purchase of Shares  pursuant to the Offer.  Under the  provisions of the HSR Act
applicable to the Offer, the purchase of Shares pursuant to the Offer may not be
consummated  until the expiration of a 15 calendar-day  waiting period following
the filing by Crane and notification to the Company of such filing. Accordingly,
it is expected that the waiting period under the HSR Act applicable to the Offer
will expire at 11:59 p.m.,  Eastern  time,  on September  1, 1998,  unless early
termination  of the  waiting  period  is  granted  or the  FTC or the  Antitrust
Division  extends the waiting  period by requesting  additional  information  or
documentary  material from Crane.  If either the FTC or the  Antitrust  Division
were to request additional  information or documentary  material from Crane, the
waiting  period would expire at 11:59 p.m.,  Eastern time, on the tenth calendar
day  after  the date of  substantial  compliance  by Crane  with  such  request.
Thereafter, the waiting period could be extended by

                               36
<PAGE>
court  order or by consent  of Crane.  If the  acquisition  of Shares is delayed
pursuant  to a  request  by the FTC or the  Antitrust  Division  for  additional
information or documentary  material pursuant to the HSR Act, the Offer may, but
need not,  be extended  and in any event the  purchase of and payment for Shares
will be  deferred  until ten days after the  request is  substantially  complied
with,  unless  the  waiting  period  is  sooner  terminated  by the  FTC and the
Antitrust  Division.  Only one  extension of such waiting  period  pursuant to a
request for  additional  information  is authorized by the HSR Act and the rules
promulgated  thereunder,  except by court order or by consent of Crane. Any such
extension of the waiting period will not give rise to any withdrawal  rights not
otherwise provided for by applicable law. See Section 4. Although the Company is
required to file certain information and documentary material with the Antitrust
Division and the FTC in connection with the Offer, neither the Company's failure
to make such  filings nor a request from the  Antitrust  Division or the FTC for
additional  information or documentary  material made to the Company will extend
the waiting period.

   The FTC and the Antitrust Division  frequently  scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Shares by
the Purchaser pursuant to the Offer. At any time before or after the purchase by
the Purchaser of Shares  pursuant to the Offer,  either the FTC or the Antitrust
Division could take such action under the antitrust  laws as it deems  necessary
or desirable in the public interest, including seeking to enjoin the purchase of
Shares pursuant to the Offer or seeking the  divestiture of Shares  purchased by
the  Purchaser  or  the  divestiture  of  substantial   assets  of  Crane,   its
subsidiaries or the Company.  Private  parties and state  attorneys  general may
also bring legal action under U.S. federal or state antitrust laws under certain
circumstances.

   Based upon an examination of publicly available  information  relating to the
businesses  in which the  Company is  engaged,  Crane is  confident  that it can
overcome any antitrust  objections of the Antitrust  Division and the FTC or any
other party to the  acquisition of Shares  pursuant to the Offer and the Merger.
Nevertheless,  there  can be no  assurance  that a  challenge  to the  Offer  on
antitrust  grounds will not be made,  or, if such  challenge  is made,  what the
result will be.

16. CERTAIN FEES AND EXPENSES

   Beacon Hill Partners,  Inc. has been retained by the Purchaser as Information
Agent in connection with the Offer. The Information Agent may contact holders of
Shares by mail,  telephone,  telex,  telegraph  and personal  interview  and may
request  brokers,  dealers and other nominee  shareholders  to forward  material
relating to the Offer to beneficial owners of Shares. The Purchaser will pay the
Information Agent reasonable and customary compensation for all such services in
addition to  reimbursing  the  Information  Agent for  reasonable  out-of-pocket
expenses in connection therewith.

   In addition, First Chicago Trust Company of New York has been retained as the
Depositary.  The  Purchaser  will pay the  Depositary  reasonable  and customary
compensation  for its services in connection with the Offer,  will reimburse the
Depositary for its reasonable out-of-pocket expenses in connection therewith and
will  indemnify  the  Depositary  against  certain  liabilities  and expenses in
connection  therewith,  including  certain  liabilities  under the U.S.  federal
securities laws.

   Except as set forth above,  neither Crane nor the Purchaser will pay any fees
or commissions to any broker,  dealer or other person for soliciting  tenders of
Shares  pursuant  to the Offer.  Brokers,  dealers,  commercial  banks and trust
companies and other nominees will,  upon request,  be reimbursed by Crane or the
Purchaser  for  customary  clerical  and  mailing  expenses  incurred by them in
forwarding offering materials to their customers.

17. MISCELLANEOUS

   The  Offer is not being  made to (nor will  tenders  be  accepted  from or on
behalf of) holders of Shares residing in any jurisdiction in which the making of
the  Offer  or the  acceptance  thereof  would  not be in  compliance  with  the
securities, blue sky or other laws of such jurisdiction.  However, the Purchaser
may, in its  discretion,  take such action as it may deem  necessary to make the
Offer in any  jurisdiction  and  extend  the Offer to  holders of Shares in such
jurisdiction.

                               37
<PAGE>
   In any jurisdiction where the securities,  blue sky or other laws require the
Offer to be made by a licensed broker or dealer,  the Offer will be deemed to be
made on behalf of the  Purchaser  by one or more  registered  brokers or dealers
that are licensed under the laws of such jurisdiction.

   Crane and the  Purchaser  have filed with the  Commission  a Schedule  14D-l,
together  with  exhibits,  pursuant  to Rule  14d-3  of the  General  Rules  and
Regulations under the Exchange Act,  furnishing certain  additional  information
with respect to the Offer, and may file amendments thereto.  Such Schedule 14D-l
and any amendments thereto,  including exhibits,  may be examined and copies may
be obtained from the office of the Commission in the same manner as described in
Section 8 with respect to information concerning the Company, except that copies
will not be available at the regional offices of the Commission.

   NO  PERSON  HAS  BEEN  AUTHORIZED  TO GIVE  ANY  INFORMATION  OR TO MAKE  ANY
REPRESENTATION  ON BEHALF OF CRANE OR THE  PURCHASER NOT CONTAINED IN THIS OFFER
TO PURCHASE  OR IN THE LETTER OF  TRANSMITTAL  AND,  IF GIVEN OR MADE,  ANY SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

   Neither the delivery of the Offer to Purchase  nor any  purchase  pursuant to
the Offer shall under any  circumstances  create any implication  that there has
been no change in the  affairs of Crane,  the  Purchaser,  the Company or any of
their  respective  subsidiaries  since  the  date  as of  which  information  is
furnished or the date of this Offer to Purchase.

dissenters  rights in connection with any corporate action or other  transaction
that would otherwise not entitle such shareholder to dissenters rights.

   (d) Notice of dissenters rights.  Unless otherwise provided by statute,  if a
proposed  corporate action that would give rise to dissenters  rights under this
subpart is  submitted  to a vote at a meeting of  shareholders,  there  shall be
included in or enclosed with the notice of meeting:

   (1) A statement of the proposed action and a statement that the  shareholders
have a right to dissent and obtain  payment of the fair value of their shares by
complying with the terms of this subchapter; and

   (2) A copy of this subchapter.

   (e)  Other  statutes.  The  procedures  of  this  subchapter  shall  also  be
applicable to any transaction described in any statute other than this part that
makes  reference  to this  subchapter  for the  purpose of  granting  dissenters
rights.

   (f) Certain  provisions of articles  ineffective.  This subchapter may not be
relaxed by any provision of the articles.

   (g) Cross references. See sections 1105 (relating to restriction on equitable
relief),  1904 (relating to de facto  transaction  doctrine  abolished) and 2512
(relating to dissenters rights procedure) .

1572 DEFINITIONS

   The following words and phrases when used in this  subchapter  shall have the
meanings  given to them in this  section  unless the context  clearly  indicates
otherwise:

   "Corporation." The issuer of the shares held or owned by the dissenter before
the  corporate  action or the  successor  by  merger,  consolidation,  division,
conversion or otherwise of that issuer.  A plan of division may designate  which
of the resulting  corporations is the successor  corporation for the purposes of
this  subchapter.  The  successor  corporation  in a  division  shall  have sole
responsibility  for  payments to  dissenters  and other  liabilities  under this
subchapter except as otherwise provided in the plan of division.

   "Dissenter."  A shareholder  or beneficial  owner who is entitled to and does
assert  dissenters  rights under this subchapter and who has performed every act
required up to the time involved for the assertion of those rights.

   "Fair Value." The fair value of shares immediately before the effectuation of
the  corporate  action to which the dissenter  objects,  taking into account all
relevant factors, but excluding any appreciation or depreciation in anticipation
of the corporate action.

   "Interest."  Interest from the effective  date of the corporate  action until
the  date of  payment  at  such  rate as is fair  and  equitable  under  all the
circumstances,  taking into account all relevant factors,  including the average
rate currently paid by the corporation on its principal bank loans.

                              II-2
<PAGE>
1573 RECORD AND BENEFICIAL HOLDERS AND OWNERS

   (a)  Record  holders  of  shares.  A record  holder of  shares of a  business
corporation  may  assert  dissenters  rights as to fewer  than all of the shares
registered in his name only if he dissents with respect to all the shares of the
same class or series beneficially owned by any one person and discloses the name
and address of the person or persons on whose behalf he dissents. In that event,
his rights shall be determined as if the shares as to which he has dissented and
his other shares were registered in the names of different shareholders.

   (b) Beneficial  owners of shares.  A beneficial owner of shares of a business
corporation  who is not the  record  holder may assert  dissenters  rights  with
respect  to shares  held on his  behalf  and shall be  treated  as a  dissenting
shareholder  under the terms of this subchapter if he submits to the corporation
not later than the time of the assertion of dissenters  rights a written consent
of the record  holder.  A beneficial  owner may not dissent with respect to some
but less than all shares of the same class or series owned by the owner, whether
or not the shares so owned by him are registered in his name.

1574 NOTICE OF INTENTION TO DISSENT

   If the  proposed  corporate  action is  submitted  to a vote at a meeting  of
shareholders  of a business  corporation,  any person who wishes to dissent  and
obtain  payment  of the fair  market  value of his  shares  must  file  with the
corporation,  prior to the vote, a written notice of intention to demand that he
be paid the fair value for his  shares if the  proposed  action is  effectuated,
must effect no change in the beneficial ownership of his shares from the date of
such filing  continuously  through the effective date of the proposed action and
must refrain from voting his shares in approval of such action.  A dissenter who
fails in any respect shall not acquire any right to payment of the fair value of
his  shares  under  this  subchapter.  Neither  a proxy nor a vote  against  the
proposed  corporate  action shall constitute the written notice required by this
section.

1575 NOTICE TO DEMAND PAYMENT

   (a)  General  rule.  If the  proposed  corporate  action is  approved  by the
required  vote at a meeting  of  shareholders  of a  business  corporation,  the
corporation shall mail a further notice to all dissenters who gave due notice of
intention to demand  payment of the fair value of their shares and who refrained
from voting in favor of the proposed action. If the proposed corporate action is
to be taken without a vote of  shareholders,  the corporation  shall send to all
shareholders who are entitled to dissent and demand payment of the fair value of
their shares a notice of the adoption of the plan or other corporate  action. In
either case, the notice shall:

   (1) State where and when a demand for payment  must be sent and  certificates
for certificated shares must be deposited in order to obtain payment.

   (2) Inform holders of uncertificated shares to what extent transfer of shares
will be restricted from the time that demand for payment is received.

   (3)  Supply  a form  for  demanding  payment  that  includes  a  request  for
certification  of the date on which  the  shareholder,  or the  person  on whose
behalf the shareholder dissents, acquired beneficial ownership of the shares.

   (4) Be accompanied by a copy of this subchapter.

   (b) Time for receipt of demand for  payment.  The time set for receipt of the
demand and deposit of  certificated  shares  shall be not less than 30 days from
the mailing of the notice.

1576 FAILURE TO COMPLY WITH NOTICE TO DEMAND PAYMENT, ETC.

   (a) Effect of  failure of  shareholder  to act.  A  shareholder  who fails to
timely demand payment,  or fails (in the case of certificated  shares) to timely
deposit certificates, as required by a notice pursuant to section 1575 (relating
to notice to demand  payment) shall not have any right under this  subchapter to
receive payment of the fair value of his shares.

                              II-3
<PAGE>
   (b) Restriction on  uncertificated  shares. If the shares are not represented
by certificates,  the business  corporation may restrict their transfer from the
time of  receipt  of demand  for  payment  until  effectuation  of the  proposed
corporate  action or the  release  of  restrictions  under the terms of  section
1577(a) (relating to failure to effectuate corporate action) .

   (c) Rights  retained by  shareholder.  The  dissenter  shall retain all other
rights of a shareholder  until those rights are modified by  effectuation of the
proposed corporate action.

1577 RELEASE OF RESTRICTIONS OR PAYMENT FOR SHARES.

   (a) Failure to effectuate corporate action. Within 60 days after the date set
for demanding payment and depositing  certificates,  if the business corporation
has  not  effectuated  the  proposed  corporate  action,  it  shall  return  any
certificates that have been deposited and release uncertificated shares from any
transfer restrictions imposed by reason of the demand for payment.

   (b) Renewal of notice to demand payment. When uncertificated shares have been
released  from  transfer  restrictions  and  deposited  certificates  have  been
returned,  the corporation may at any later time send a new notice conforming to
the  requirements  of section 1575  (relating to notice to demand  payment) with
like effect.

   (c)  Payment of fair  value of shares.  Promptly  after  effectuation  of the
proposed  corporate  action, or upon timely receipt of demand for payment if the
corporate  action has already been  effectuated,  the  corporation  shall either
remit to dissenters who have made demand and (if their shares are  certificated)
have deposited their  certificates the amount that the corporation  estimates to
be the fair value of the shares, or give written notice that no remittance under
this section will be made. The remittance or notice shall be accompanied by:

   (1) The closing  balance  sheet and  statement of income of the issuer of the
shares held or owned by the  dissenter for a fiscal year ending not more than 16
months  before  the date of  remittance  or  notice  together  with  the  latest
available interim financial statements.

   (2) A  statement  of the  corporation's  estimate  of the  fair  value of the
shares.

   (3) A notice of the right of the dissenter to demand payment or  supplemental
payment, as the case may be, accompanied by a copy of this subchapter.

   (d) Failure to make payment.  If the corporation does not remit the amount of
its estimate of the fair value of the shares as provided by  subsection  (c), it
shall   return  any   certificates   that  have  been   deposited   and  release
uncertificated  shares from any transfer  restrictions  imposed by reason of the
demand for payment.  The corporation may make a notation on any such certificate
or on the records of the corporation relating to any such uncertificated  shares
that such demand has been made.  If shares with  respect to which  notation  has
been so made shall be transferred,  each new certificate  issued therefor or the
records relating to any transferred  uncertificated  shares shall bear a similar
notation,  together with the name of the original  dissenting holder or owner of
such shares.  A transferee of such shares shall not acquire by such transfer any
rights in the corporation other than those that the original dissenter had after
making demand for payment of their fair value.

1578 ESTIMATE BY DISSENTER OF FAIR VALUE OF SHARES.

   (a) General rule. If the business corporation gives notice of its estimate of
the fair value of the shares,  without  remitting such amount, or remits payment
of its  estimate  of the fair  value of a  dissenter's  shares as  permitted  by
section 1577(c)  (relating to payment of fair value of shares) and the dissenter
believes  that the amount  stated or remitted is less than the fair value of his
shares, he may send to the corporation his own estimate of the fair value of the
shares,  which  shall be  deemed a  demand  for  payment  of the  amount  or the
deficiency.

   (b) Effect of failure to file estimate. Where the dissenter does not file his
own  estimate  under  subsection  (a)  within 30 days  after the  mailing by the
corporation of its remittance or notice,  the dissenter  shall be entitled to no
more than the amount stated in the notice or remitted to him by the corporation.

                              II-4
<PAGE>
1579 VALUATION PROCEEDINGS GENERALLY.

   (a) General rule. Within 60 days after the latest of:

   (1) Effectuation of the proposed corporate action;

   (2) Timely receipt of any demands for payment under section 1575 (relating to
notice to demand payment); or

   (3) Timely  receipt of any  estimates  pursuant to section 1578  (relating to
estimate by dissenter of fair value of shares);

If any demands for payment remain unsettled,  the business  corporation may file
in court an application for relief  requesting that the fair value of the shares
be determined by the court.

   (b) Mandatory joinder of dissenters. All dissenters, wherever residing, whose
demands have not been settled  shall be made parties to the  proceeding as in an
action against their shares.  A copy of the application  shall be served on each
such dissenter.  If a dissenter is a nonresident,  the copy may be served on him
in the manner  provided  or  prescribed  by or  pursuant  to 42  Pa.C.S.  Ch. 53
(relating to bases of jurisdiction and interstate and international procedure) .

   (c) Jurisdiction of the court. The jurisdiction of the court shall be plenary
and  exclusive.  The court may  appoint an  appraiser  to receive  evidence  and
recommend a decision on the issue of fair value.  The appraiser  shall have such
power and  authority as may be specified in the order of  appointment  or in any
amendment thereof.

   (d) Measure of recovery. Each dissenter who is made a party shall be entitled
to  recover  the amount by which the fair value of his shares is found to exceed
the amount, if any, previously remitted, plus interest.

   (e) Effect of corporation's  failure to file application.  If the corporation
fails to file an  application  as provided in subsection  (a), any dissenter who
made a demand and who has not already  settled his claim against the corporation
may do so in the name of the  corporation  at any time  within 30 days after the
expiration of the 60-day  period.  If a dissenter  does not file an  application
within the 30-day period,  each dissenter  entitled to file an application shall
be paid the corporation's  estimate of the fair value of the shares and no more,
and may bring an action to recover any amount not previously remitted.

1580 COSTS AND EXPENSES OF VALUATION PROCEEDINGS.

   (a) General rule. The costs and expenses of any proceeding under section 1579
(relating  to  valuation  proceedings   generally),   including  the  reasonable
compensation  and expenses of the  appraiser  appointed  by the court,  shall be
determined  by the court and assessed  against the business  corporation  except
that any part of the costs and expenses may be  apportioned  and assessed as the
court deems  appropriate  against all or some of the  dissenters who are parties
and whose action in demanding  supplemental payment under section 1578 (relating
to  estimate  by  dissenter  of fair  value of  shares)  the  court  finds to be
dilatory, obdurate, arbitrary, vexatious or in bad faith.

   (b)  Assessment  of  counsel  fees and  expert  fees where lack of good faith
appears.  Fees and expenses of counsel and of experts for the respective parties
may be assessed as the court deems  appropriate  against the  corporation and in
favor of any or all dissenters if the corporation failed to comply substantially
with the  requirements of this subchapter any may be assessed against either the
corporation or a dissenter, in favor of any other party, if the court finds that
the party against whom the fees and expenses are assessed  acted in bad faith or
in a dilatory,  obdurate, arbitrary or vexatious manner in respect to the rights
provided by this subchapter.

   (c) Award of fees for benefits to other  dissenters.  If the court finds that
the services of counsel for any dissenter were of  substantial  benefit to other
dissenters   similarly   situated  and  should  not  be  assessed   against  the
corporation, it may award to those counsel reasonable fees to be paid out of the
amounts awarded to the dissenters who were benefited.

                          AGREEMENT AND PLAN OF MERGER


      AGREEMENT  AND PLAN OF MERGER,  dated as of August 11,  1998,  among CRANE
CO.,  a  Delaware  corporation  ("Crane"  or  "Parent"),  LTI  MERGER,  INC.,  a
Pennsylvania  corporation and wholly owned  subsidiary of Crane (the "Purchaser"
or "Merger Sub"),  and LIBERTY  TECHNOLOGIES,  INC., a Pennsylvania  corporation
(the "Company").

      WHEREAS,  the respective  Boards of Directors of Crane,  the Purchaser and
the Company have approved the acquisition of the Company by Crane upon the terms
and subject to the conditions set forth in this Agreement; and

      WHEREAS,  in furtherance of such acquisition,  Crane proposes to cause the
Purchaser  to make a tender  offer  (as it may be  amended  from time to time as
permitted  under this  Agreement,  the "Offer") to purchase all the  outstanding
shares of common  stock,  par value $.01 per  share,  of the  Company  ("Company
Common Stock" or "Shares"),  including the associated  preferred  stock purchase
rights (the "Rights")  issued under the Amended and Restated  Rights  Agreement,
dated October 6, 1997, between the Company and StockTrans, Inc., as rights agent
(the "Rights  Agreement"),  at a purchase price of $3.50 per share (such amount,
or any greater amount to be paid per share of Company Common Stock in the Offer,
being referred to as the "Per Share  Amount"),  net to the seller in cash,  upon
the terms and subject to the  conditions  set forth in this Agreement and in the
Offer,  and the Board of  Directors of the Company has approved the Offer and is
recommending that the Company's  shareholders  accept the Offer and tender their
shares of Company Common Stock pursuant to the Offer; and

      WHEREAS, also in furtherance of such acquisition, the respective Boards of
Directors  of Crane,  Purchaser  and the  Company  have  approved  the merger of
Purchaser with and into the Company (the "Merger") upon the terms and subject to
the conditions set forth in this Agreement and in accordance with the provisions
of the Pennsylvania  Business Corporation Law, as amended (the "PBCL"),  whereby
each  issued and  outstanding  share of Company  Common  Stock other than shares
owned by the Company or by Crane,  the Purchaser or any wholly owned  subsidiary
of the Company, Crane or the Purchaser and other than Dissenting Shares, will be
converted into the right to receive the Per Share Amount; and

      WHEREAS,  concurrently  with the execution and delivery of this  Agreement
and as a condition  and  inducement  to Crane's  willingness  to enter into this
Agreement,  Crane has  entered  into (i) a Stock  Option  Agreement  (the "Stock
Option  Agreement")  with the Company  pursuant to which the Company has granted
Crane an option to acquire shares of Company  Common Stock and (ii)  Shareholder
Agreements  (the  "Shareholder  Agreements")  with certain  shareholders  of the
Company pursuant to which, among other things,  such shareholders have agreed to
tender their Shares pursuant to the Offer and have granted to Crane an option to
otherwise purchase such Shares;

<PAGE>
      NOW,  THEREFORE,  in  consideration  of the  representations,  warranties,
covenants and agreements contained in this Agreement, the parties,  intending to
be legally bound, agree as follows:

                                    ARTICLE I
                            THE OFFER AND THE MERGER

      SECTION  1.01.     The  Offer.  (a) Provided that this Agreement shall not
have been  terminated  in  accordance  with  Article  VII hereof and none of the
events set forth in Annex II hereto (the "Tender Offer  Conditions")  shall have
occurred,  as  promptly  as  practicable  but in no event  later  than the fifth
business day from the date of this Agreement, Crane shall cause the Purchaser to
commence (within the meaning of Rule 14d-2 under the Securities  Exchange Act of
1934, as amended  (including the rules and regulations  promulgated  thereunder,
the  "Exchange  Act")) an offer to purchase  all  outstanding  shares of Company
Common Stock,  together with associated  Rights (all references herein to shares
of Company Common Stock in the context of the Offer being deemed to include such
Rights) at the Per Share Price,  shall, after affording the Company a reasonable
opportunity to review and comment thereon, file all necessary documents with the
Securities and Exchange Commission (the "SEC") in connection with the Offer (the
"Offer  Documents")  and shall  consummate  the Offer,  subject to the terms and
conditions thereof. The obligation of the Purchaser to accept for payment or pay
for any shares of Company  Common Stock  tendered  pursuant to the Offer will be
subject only to the satisfaction of the conditions set forth in Annex II hereto.

            (b) Without the prior written consent of the Company,  the Purchaser
shall not decrease the Offer price or change the form of  consideration  payable
in the Offer, decrease the number of shares of Company Common Stock sought to be
purchased in the Offer,  impose additional  conditions to the Offer or amend any
other  term of the  Offer in any  manner  adverse  to the  holders  of shares of
Company  Common  Stock.  The Offer  shall  remain open until the date that is 20
business  days (as such term is defined in Rule  14d-1(c)(6)  under the Exchange
Act) after the  commencement of the Offer (the  "Expiration  Date"),  unless the
Purchaser  shall  have  extended  the period of time for which the Offer is open
pursuant to, and in accordance  with, the two succeeding  sentences or as may be
required by applicable law, in which event the term "Expiration Date" shall mean
the latest time and date as the Offer,  as so  extended,  may expire.  If at any
Expiration  Date, any of the Tender Offer Conditions are not satisfied or waived
by the Purchaser,  the Purchaser may extend the Offer from time to time. Subject
to the terms of the Offer and this  Agreement  and the  satisfaction  of all the
Tender Offer Conditions as of any Expiration Date, the Purchaser will accept for
payment and pay for all shares  validly  tendered and not withdrawn  pursuant to
the  Offer  as soon as  practicable  after  such  Expiration  Date of the  Offer
consistent  with  applicable  law,  provided  that,  if all of the Tender  Offer
Conditions are satisfied and more than 65% but less than 80% of the  outstanding
shares of Company  Common Stock on a fully  diluted basis  (including  shares of
Company Common Stock  issuable upon exercise of  outstanding  options to acquire
shares of Company Common Stock) have been validly  tendered and not withdrawn in
the Offer, the Purchaser shall have the right, in its sole discretion, to extend
the Offer from time to time for up to a maximum of 10  additional  business days
in the aggregate for all such extensions  provided the Purchaser agrees to waive
the conditions set forth in paragraphs (c), (f) and (g) of Annex II.

                                       2
<PAGE>
            (c) Crane and the Purchaser  represent that the Offer Documents will
comply in all  material  respects  with the  provisions  of  applicable  federal
securities  laws  and,  on the date  filed  with  the SEC and on the date  first
published,  sent or given to the Company's  shareholders,  shall not contain any
untrue  statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements  made therein,
in light of the circumstances under which they were made, not misleading, except
that no  representation  is made by  Crane  or the  Purchaser  with  respect  to
information  derived  from the Company SEC Reports or supplied by the Company in
writing  expressly for inclusion in the Offer  Documents.  Each of Crane and the
Purchaser,  on the one hand, and the Company, on the other hand, agrees promptly
to correct any information  provided by it for use in the Offer Documents if and
to the extent  that it shall have become  false or  misleading  in any  material
respect  and each of Crane and the  Purchaser  further  agrees to take all steps
necessary to cause the Offer  Documents as so corrected to be filed with the SEC
and to be disseminated  to shareholders of the Company,  in each case, as and to
the extent required by applicable federal securities laws.

      SECTION 1.02.     Company  Actions. (a) The Company shall, after affording
Crane a reasonable  opportunity to review and comment thereon, file with the SEC
and mail to the  holders of shares of  Company  Common  Stock,  as  promptly  as
practicable  on the date of the filing by Crane and the  Purchaser  of the Offer
Documents, a  Solicitation/Recommendation  Statement on Schedule 14D-9 (together
with any amendments or supplements thereto, the "Schedule 14D-9") reflecting the
recommendation  of the Board of  Directors of the Company that holders of shares
of Company  Common Stock  tender  their  shares  pursuant to the Offer and shall
disseminate the Schedule 14D-9 as required by Rule 14d-9  promulgated  under the
Exchange  Act.  The  Schedule  14D-9  will set  forth,  and the  Company  hereby
represents, that the Board of Directors of the Company, at a meeting duly called
and  held,  has  (i)  determined  by  vote  of its  directors  that  each of the
transactions contemplated hereby, including each of the Offer and the Merger, is
fair to and in the best  interests  of the  Company and its  shareholders,  (ii)
approved the Offer,  the Merger,  the Stock Option Agreement and the Shareholder
Agreements,  (iii)  recommended  acceptance  of the Offer and  approval  of this
Agreement  by the  Company's  shareholders,  and (iv)  taken  all  other  action
necessary to render  Section 2538 and Subchapter F of Chapter 25 of the PBCL and
the Rights  inapplicable to the Offer and the Merger.  Such  recommendation  and
approval may be withdrawn,  modified or amended only to the extent  permitted by
Section  5.02(b).  The Company further  represents  that, prior to the execution
hereof,  Legg Mason Wood Walker, Inc. has delivered to the Board of Directors of
the Company its written  opinion that, as of August 10, 1998, the  consideration
to be received by the holders of shares of Company  Common Stock pursuant to the
Offer and the  Merger is fair to the  Company's  shareholders  from a  financial
point of view.  The  Company  hereby  consents  to the  inclusion  in the  Offer
Documents  of the  recommendation  of the  Board  of  Directors  of the  Company
described in this Section 1.02(a).

            (b) The Company  represents  that the Schedule  14D-9 will comply in
all material respects with the provisions of applicable  federal securities laws
and,  on the date filed with the SEC and on the date  first  published,  sent or
given to the Company's shareholders, shall not contain any untrue statement of a
material fact or omit to state any material  fact required to be stated  therein
or  necessary  in order to make the  statements  made  therein,  in light of the
circumstances  under  which  they were  made,  not  misleading,  except  that no
representation  is made by the Company with respect to  information  supplied by
Crane or the Purchaser in writing

                                       3
<PAGE>
expressly for inclusion in the Schedule 14D-9.  Each of the Company,  on the one
hand,  and Parent and the  Purchaser,  on the other  hand,  agrees  promptly  to
correct any information provided by either of them for use in the Schedule 14D-9
if and to the  extent  that it shall  have  become  false or  misleading  in any
material respect,  and the Company further agrees to take all steps necessary to
cause the  Schedule  14D-9 as so  corrected  to be filed  with the SEC and to be
disseminated  to the holders of shares of Company Common Stock, in each case, as
and to the extent required by applicable federal securities law.

            (c) In connection with the Offer,  the Company will promptly furnish
the Purchaser with mailing labels,  security  position  listings,  any available
non-objecting  beneficial owner lists and any available listing or computer list
containing  the names and  addresses of the record  holders of shares of Company
Common  Stock as of the most  recent  practicable  date and  shall  furnish  the
Purchaser with such additional available information (including, but not limited
to,  updated  lists of  holders  of shares  of  Company  Common  Stock and their
addresses,  mailing  labels and lists of security  positions  and  non-objecting
beneficial owner lists) and such other assistance as the Purchaser or its agents
may reasonably  request in  communicating  the Offer to the Company's record and
beneficial  shareholders.  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, Crane, the Purchaser and
their affiliates,  associates,  agents and advisors, shall keep such information
confidential and use the information contained in any such labels,  listings and
files only in  connection  with the Offer and the Merger  and,  should the Offer
terminate or if this Agreement shall be terminated,  will deliver to the Company
all copies of such information then in their possession.

            SECTION 1.03.   Directors. (a) Subject to compliance with applicable
law,  promptly upon the payment by the  Purchaser  for shares of Company  Common
Stock which  represent  at least a majority of the  Company  Common  Stock (on a
fully  diluted  basis)  pursuant to the Offer and from time to time  thereafter,
Crane shall be entitled to designate such number of directors, rounded up to the
next whole  number,  on the Board of Directors of the Company as is equal to the
product  of the total  number of  directors  on the  Board of  Directors  of the
Company  (determined  after giving effect to the directors  elected  pursuant to
this sentence)  multiplied by the percentage that the aggregate number of shares
of Company Common Stock  beneficially  owned by Crane or its affiliates bears to
the total number of shares of Company Common Stock outstanding,  and the Company
shall,  upon  request of Crane,  promptly  take all  actions  (but  specifically
excluding  the calling of a  shareholders  meeting)  necessary to cause  Crane's
designees to be so elected, including, if necessary, amending the By-laws of the
Company to the extent  permitted  to be  amended by the Board of  Directors  and
seeking the resignations of one or more existing directors;  provided,  however,
that prior to the  Effective  Time,  the Board of Directors of the Company shall
always have not less than two members  who are  directors  of the Company on the
date hereof ("Current  Directors")  and, in Crane's sole discretion,  up to five
Current  Directors.  If the number of Current  Directors is reduced prior to the
Effective  Time below the number of Current  Directors so specified by Crane due
to the death or  resignation of one or more of the Current  Directors,  then the
remaining  director  or  directors  who is or are  Current  Directors  shall  be
entitled to designate,  by majority action of the remaining Current Directors or
action of the sole remaining Current Director,  one or more persons, as the case
may be, that has not been  designated  by, and is not an Affiliate  of, Crane to
fill such vacancy or vacancies  and who shall be deemed to be Current  Directors
for all purposes of this Agreement.

<PAGE>
            (b) The Company's  obligations to appoint  Crane's  designees to the
Board of  Directors  of the  Company  shall be subject  to Section  14(f) of the
Exchange Act and Rule 14f-1  thereunder.  The Company  shall  promptly  take all
actions  required  pursuant  to such  Section  and Rule in order to fulfill  its
obligations under this Section 1.03 and shall include in the Schedule 14D-9 such
information  with respect to the Company and its  officers  and  directors as is
required under such Section and Rule in order to fulfill its  obligations  under
this Section 1.03.  Crane will supply  promptly,  and in any event no later than
the date the appointment of such directors is effective,  any  information  with
respect to itself and its officers,  directors and  affiliates  required by such
Section and Rule to the Company.

            (c)  Following  the  election or  appointment  of Crane's  designees
pursuant to this Section 1.03 and prior the  Effective  Time,  any  amendment or
termination  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 Crane or
the Purchaser or waiver of any of the Company's rights  hereunder,  will require
the concurrence of a majority of the directors of the Company then in office who
are Current Directors (or in the case where there are two or fewer directors who
are  Current  Directors,  the  concurrence  of one  director  who  is a  Current
Director).

      SECTION 1.04.     The Merger. Upon the terms and subject to the conditions
set forth in this Agreement,  and in accordance with the PBCL,  Merger Sub shall
be  merged  with and into the  Company  at the  Effective  Time.  Following  the
Effective Time, the separate  corporate  existence of Merger Sub shall cease and
the  Company  shall  continue  as  the  surviving  corporation  (the  "Surviving
Corporation")  and shall succeed to and assume all the rights and obligations of
Merger Sub in accordance with the PBCL.

      SECTION 1.05.     Closing.  The closing of the Merger (the "Closing") will
take place at 10:00 a.m. on a date to be specified by the parties (the  "Closing
Date"),  which shall be as soon as practicable  after  satisfaction or waiver of
the conditions set forth in Section 6.01, at the offices of Pepper  Hamilton LLP
in Philadelphia, Pennsylvania unless another time, date or place is agreed to in
writing by the parties hereto.

      SECTION  1.06.     Effective  Time.  Subject  to the  provisions  of  this
Agreement,  on the Closing Date,  the parties shall file articles of merger (the
"Articles of Merger") executed in accordance with the relevant provisions of the
PBCL and shall make all other filings or recordings required under the PBCL. The
Merger  shall  become  effective at such time as the Articles of Merger are duly
filed with the  Pennsylvania  Secretary of State,  or at such subsequent time as
Crane and the Company  shall agree and as is specified in the Articles of Merger
(the time the Merger  becomes  effective  being  hereinafter  referred to as the
"Effective Time").

      SECTION 1.07.     Effects of the Merger. The Merger shall have the effects
specified in Section 1929 of the PBCL.


                                       5
<PAGE>
      SECTION  1.08.     Articles  of Incorporation and By-laws.  (a) The Second

Merger Sub immediately prior to the Effective Time shall be the directors of the
Surviving  Corporation,  until the  earlier of their  resignation  or removal or

may be. The Company will obtain such  resignations as may be necessary to effect
the foregoing.

      SECTION  1.10.     Officers of the Surviving Corporation.  The officers of
Merger Sub immediately  prior to the Effective Time shall be the officers of the
Surviving  Corporation,  until the  earlier of their  resignation  or removal or
until their  respective  successors are duly elected and qualified,  as the case
may be.

      SECTION 1.11.     Shareholders' Meeting. (a) If required by applicable law
in  order  to  consummate  the  Merger,  as soon as  practicable  following  the
acceptance  for payment of and payment for shares of Company Common Stock by the
Purchaser  pursuant  to the Offer,  the  Company,  acting  through  the Board of
Directors of the Company, shall, in accordance with applicable law:

                   (i) duly call,  give  notice of,  convene  and hold a special
            meeting of its shareholders (the "Company Shareholders Meeting") for
            the purpose of considering and taking action upon this Agreement;

                   (ii)  prepare  and  file  with  the SEC a  preliminary  proxy
            statement relating to this Agreement, and use its reasonable efforts
            (x) to obtain and furnish the information required to be included by
            the SEC in the Proxy Statement (as hereinafter  defined) and cause a
            definitive  proxy statement (the "Proxy  Statement") to be mailed to
            its  shareholders  and (y) to obtain the necessary  approvals of the
            Merger and this Agreement by its shareholders; and

                   (iii) subject to Section 5.02, include in the Proxy Statement
            the  recommendation  of the Board of  Directors  of the Company that
            shareholders  of the  Company  vote in favor of the  approval of the
            Merger and this Agreement.

            (b) Crane agrees that it will vote, or cause to be voted, all of the
shares of Company  Common  Stock then owned by it, the  Purchaser  or any of its
other Subsidiaries in favor of the approval of the Merger and of this Agreement.
Following the  consummation of the Offer, if required by applicable law in order
to consummate the Merger,  Crane shall use its best efforts to cause the Company
to take the actions set forth in Section 1.11(a).

                                   ARTICLE II
                    EFFECT OF THE MERGER ON THE CAPITAL STOCK
                         OF THE CONSTITUENT CORPORATIONS

      SECTION  2.01.     Effect  on Capital Stock.  As of the Effective Time, by
virtue of the  Merger  and  without  any action on the part of the holder of any
shares of Company Common Stock:

            (a) Capital Stock of Merger Sub. Each issued and  outstanding  share
of capital stock of Merger Sub shall be converted into and become one fully paid
and nonassessable share of Common Stock of the Surviving Corporation.

            (b) Cancellation  of Treasury Stock  and Stock Owned by Crane or the
Purchaser. Each share of Company Common Stock that is owned by the Company or by
Crane or the Purchaser or any wholly owned  subsidiary of the Company,  Crane or
the  Purchaser  shall  automatically  be canceled and retired and shall cease to
exist, and no consideration shall be delivered in exchange therefor.

            (c) Conversion of Company Common Stock.  Each issued and outstanding
share of Company  Common Stock  (other than shares to be canceled in  accordance
with Section 2.01(b) and other than  Dissenting  Shares) shall be converted into
the right to receive the Per Share Amount in cash, without interest (the "Merger
Consideration").

            (d) Shares of Dissenting  Shareholders.  Notwithstanding anything in
this  Agreement to the  contrary,  any issued and  outstanding  share of Company
Common  Stock  held by a person (a  "Dissenting  Shareholder")  who  shall  have
demanded  and  perfected a right to receive  payment of the fair value of his or
her shares  pursuant  to  Subchapter  D of  Chapter 15 of the PBCL  ("Dissenting
Shares")  shall not be converted as  described in Section  2.01(c),  unless such
holder fails to comply with the  provisions of Subchapter D of Chapter 15 of the
PBCL or  withdraws  or  otherwise  loses his right to  receive  such fair  value
payment.  If, after the Effective  Time, such  Dissenting  Shareholder  fails to
comply  with  the  provisions  of  Subchapter  D of  Chapter  15 of the  PBCL or
withdraws or loses his right to receive such fair value payment, such Dissenting
Shareholder's  shares of  Company  Common  Stock  shall no longer be  considered
Dissenting  Shares for the  purposes of this  Agreement  and shall  thereupon be
deemed to have been converted into and to have become  exchangeable  for, at the
Effective   Time,   the  right  to  receive  for  each  such  share  the  Merger
Consideration,  without interest. The Company shall give Crane (i) prompt notice
of any  demands  to receive  payment  of fair value of shares of Company  Common
Stock  received by the Company and (ii) the  opportunity  to  participate in and
direct all negotiations  and proceedings  with respect to any such demands.  The
Company shall not, without the prior written consent of Crane,  make any payment
with  respect to, or settle,  offer to settle or otherwise  negotiate,  any such
demands.

            (e) Cancellation of  Company Common Stock. As of the Effective Time,
all shares of Company  Common  Stock  shall no longer be  outstanding  and shall
automatically  be  canceled  and  shall  cease to  exist,  and each  holder of a
certificate  that  immediately  prior to the 

                                       7
<PAGE>
Effective  Time   represented  any  such  shares  of  Company  Common  Stock  (a
"Certificate")  shall cease to have any rights with respect thereto,  except the
right to receive the applicable Merger Consideration,  without interest,  or, in
the case of Dissenting Shareholders,  if any, the rights, if any, accorded under
the PBCL.

      SECTION 2.02.     Exchange of Certificates.  (a) Deposit with the Exchange
Agent.  As of the Effective  Time,  Crane shall deposit with First Chicago Trust
Company  of New York or  other  independent  agent  mutually  acceptable  to the
Company  and Crane (the  "Exchange  Agent")  for the  benefit of the  holders of
shares of Company Common Stock,  for exchange  through the Exchange  Agent,  the
cash  representing  the  Merger  Consideration  (the  "Exchange  Fund")  payable
pursuant to Section 2.01(c) in exchange for outstanding shares of Company Common
Stock.

            (b) Exchange Procedures. As soon as reasonably practicable after the
Effective  Time,  the  Exchange  Agent  shall mail to each holder of record of a
Certificate or  Certificates,  (i) a letter of transmittal  (which shall specify
that delivery shall be effected, and risk of loss and title to such Certificates
shall pass,  only upon delivery of such  Certificates  to the Exchange Agent and
shall be in such form and have such other  provisions  as Crane and the  Company
may reasonably specify) and (ii) instructions for use in effecting the surrender
of such Certificates in exchange for the applicable Merger  Consideration.  Upon
surrender of such a Certificate  for  cancellation  to the Exchange  Agent or to
such other  agent or agents as may be  appointed  by Crane,  together  with such
letter of transmittal, duly executed, and such other documents as may reasonably
be required  by the  Exchange  Agent,  the holder of such  Certificate  shall be
entitled to receive cash which such holder has the right to receive  pursuant to
this Article II, and the Certificate so surrendered shall forthwith be canceled.
In the event of a transfer  of  ownership  of Company  Common  Stock that is not
registered in the transfer records of the Company,  cash may be paid 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.  Until  surrendered  as  contemplated  by this Section
2.02(b),  each Certificate  shall be deemed at any time after the Effective Time
to  represent  only  the  right  to  receive  upon  such  surrender  the  Merger
Consideration  which the holder  thereof  has the right to receive in respect of
such  Certificate  pursuant  to the  other  provisions  of this  Article  II. No
interest will be paid or will accrue on cash payable to holders of  Certificates
pursuant to the  provisions  of this Article II. Crane shall pay the charges and
expenses of the Exchange Agent.

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

            (d) Termination  of Exchange Fund. Any portion of  the Exchange Fund
that remains  undistributed  to the holders of the  Certificates  for six months
after the  Effective  Time 

                                       8
<PAGE>
shall be delivered to Crane,  upon demand,  and any holders of the  Certificates
who have not  theretofore  complied with this Article II shall  thereafter  look
only to Crane for  payment  of their  claim for any cash  comprising  the Merger
Consideration.

            (e) No Liability.  None of Crane,  the Company or the Exchange Agent
shall be liable to any  person in  respect  of any cash from the  Exchange  Fund
delivered to a public official  pursuant to any applicable  abandoned  property,
escheat or similar law.

            (f) Investment of Exchange Fund. The Exchange Agent shall invest any
cash included in the Exchange Fund, as directed by Crane, on a daily basis.  Any
interest  and other  income  resulting  from such  investments  shall be paid to
Crane.

            (g) Lost  Certificates.  If any  Certificate  shall  have been lost,
stolen or destroyed,  upon the making of an affidavit of that fact by the person
claiming such  Certificate  to be lost,  stolen or destroyed and, if required by
the  Surviving  Corporation,  the  posting  by  such  person  of a bond  in such
reasonable  amount as the Surviving  Corporation may direct as indemnity against
any claim that may be made  against it with  respect  to such  Certificate,  the
Exchange  Agent  will  issue in  exchange  for such  lost,  stolen or  destroyed
Certificate the Merger Consideration deliverable in respect thereof, pursuant to
this Agreement.

            (h) Withholding  Rights.  Crane  or  the  Exchange  Agent  shall  be
entitled  to  deduct  and  withhold  from the  consideration  otherwise  payable
pursuant to this  Agreement to any holder of shares of Company Common Stock such
amounts as Crane or the Exchange  Agent is required to deduct and withhold  with
respect to the making of such payment  under the Code or any provision of state,
local or foreign tax law. To the extent  that  amounts are so withheld  and paid
over to the appropriate  taxing  authority by Crane or the Exchange Agent,  such
withheld  amounts shall be treated for all purposes of this  Agreement as having
been paid to the  holder of the  shares of  Company  Common  Stock in respect of
which such deduction and  withholding  was made by Crane or the Exchange  Agent.
Notwithstanding  the  foregoing,  neither  Crane nor the  Exchange  Agent  shall
withhold any amounts payable  pursuant to this Agreement to any holder of shares
of Company Common Stock so long as such holder provides to Crane or the Exchange
Agent a form W-9 or W-8, as required by applicable law, certifying such holder's
exemption from back-up withholding.

      SECTION 2.03.     Treatment of Stock Options. Prior to the Effective Time,
the Company  shall take all such  actions as may be  necessary to cause (i) each
unexpired and unexercised option to acquire Company Common Stock held by current
or former directors,  officers, employees or consultants of the Company, whether
or not then  exercisable  or vested  (each,  a  "Company  Option"),  that has an
exercise price less than the Per Share Amount to be  automatically  converted at
the Effective Time into an amount equal to the difference  between the Per Share
Amount and the exercise price of the Company Option, multiplied by the number of
shares of Common Stock  issuable  immediately  prior to the Effective  Time upon
exercise  of the  Company  Option  (without  regard  to  vesting  periods  or to
restrictions on exercisability)  and (ii) each unexpired and unexercised Company
Option that has an exercise  price equal to or greater than the Per Share Amount
to be  canceled so that no Company  Option  shall have any force or effect on or
after the Effective Time.


                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY


      Except as set forth on the disclosure schedule delivered by the Company to
Crane  prior  to the  execution  of  this  Agreement  (the  "Company  Disclosure
Schedule"), the Company represents and warrants to Crane as follows:

      SECTION 3.01.     Organization,  Standing and Corporate Power. The Company
and each of its Subsidiaries is a corporation duly organized, validly subsisting
or existing and in good standing under the laws of the  jurisdiction in which it
is incorporated and has the requisite  corporate power and 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 as a foreign  corporation  and is 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, other than in such jurisdictions where the failure to be so qualified
or licensed or to be in good standing individually or in the aggregate would not
have a Material  Adverse Effect with respect to the Company and its Subsidiaries
taken as a whole.

      SECTION  3.02.     Subsidiaries.  Section  3.02 of the Company  Disclosure
Schedule sets forth a true and complete list of the Subsidiaries of the Company.
All the  outstanding  shares of capital stock of each such  Subsidiary have been
validly  issued and are fully paid and  nonassessable  and are owned directly or
indirectly  by the  Company,  free and clear of all  Liens,  except for liens of
Silicon Valley Bank (the "Silicon  Valley Bank Liens")  pursuant to the Loan and
Security  Agreement  dated May 7, 1998 among the Company and Silicon Valley Bank
(the  "Silicon  Valley  Bank  Loan").  Except  for  the  capital  stock  of  its
Subsidiaries,  the Company  does not own,  directly or  indirectly,  any capital
stock or other ownership interest in any corporation, limited liability company,
partnership, joint venture or other entity.

      SECTION  3.03.     Capital  Structure. The authorized capital stock of the
Company  consists of  20,000,000  shares of Company  Common Stock and  2,000,000

As of the date of this Agreement,  

                                       10

this Agreement,  there were no outstanding stock  appreciation  rights or rights
(other than  outstanding  Company  Options  issued  under the Stock Plans as set
forth in subparagraph (iv) above) to receive shares of Company Common Stock on a
deferred  basis granted under the Stock Plans or otherwise,  except as set forth
in the Rights Agreement.  All outstanding shares of capital stock of the Company
are, and all shares which may be issued  pursuant to any options  outstanding on
the date hereof pursuant to the Stock Plans and the Stock Option  Agreement will
be, when issued, duly authorized,  validly issued,  fully paid and nonassessable
and not subject to preemptive rights.  There are no notes, bonds,  debentures or
other indebtedness of the Company having the right to vote (or convertible into,
or  exchangeable  for,  securities  having the right to vote) on any  matters on
which shareholders of the Company may vote. Except as set forth above, as of the
date of this Agreement, there are no outstanding securities,  options, warrants,
calls, rights, commitments, agreements, arrangements or undertakings of any kind
to which the Company or any of its  Subsidiaries  was a party or by which any of
them was bound  obligating  the  Company  or any of its  Subsidiaries  to issue,
deliver or sell, or cause to be issued,  delivered or sold, additional shares of
capital  stock  or  other  voting  securities  of the  Company  or of any of its
Subsidiaries  or  obligating  the Company or any of its  Subsidiaries  to issue,
grant,  extend or enter into any such security,  option,  warrant,  call, right,
commitment,  agreement,  arrangement  or  undertaking.  As of the  date  of this
Agreement,  there are no outstanding  contractual  obligations of the Company or
any of its Subsidiaries to repurchase, redeem or otherwise acquire any shares of
capital stock of the Company or any of its Subsidiaries.  As of the date of this
Agreement,  there are no outstanding  contractual  obligations of the Company to

      SECTION  3.04.     Authority;  Noncontravention.  (a) The  Company has all
requisite  corporate  power and  authority to enter into this  Agreement and the
Stock  Option  Agreement  and,  subject (in the case of this  Agreement)  to the
Company Shareholder Approval, to consummate the transactions contemplated hereby
and thereby.  The execution and delivery of this  Agreement and the Stock Option
Agreement by the Company and the consummation by the Company of the transactions
contemplated  hereby and  thereby  have been duly  authorized  by all  necessary
corporate  action  on the  part  of the  Company,  subject,  in the  case of the
approval of this  Agreement and the  transactions  contemplated  hereby,  to the
Company Shareholder Approval. This Agreement and the Stock Option Agreement have
been duly executed and delivered by the Company and constitute valid and binding
obligations of the Company,  enforceable  against the 

                                       11
<PAGE>
Company in  accordance  with  their  terms  except as limited by (i)  applicable
bankruptcy,  insolvency,  reorganization,  moratorium  and other laws of general
application  affecting  enforcement  of  creditors'  rights  generally  and (ii)
general principles of equity,  regardless of whether asserted in a proceeding in
equity or at law;  provided,  however,  that the Company  cannot  consummate the
Merger unless and until it receives the Company Shareholder Approval.

            (b) The  execution  and  delivery  of this  Agreement  and the Stock
Option Agreement by the Company do not, and the consummation of the transactions
contemplated  hereby and thereby will not, (i) conflict  with,  or result in any
violation or breach of any  provision  of the Amended and  Restated  Articles of
Incorporation or Bylaws of the Company, (ii) except as set forth in Section 3.04
of the Company  Disclosure  Schedule,  result in any  violation or breach of, or
constitute (with or without notice or lapse of time, or both) a default (or give
rise to a right of  termination,  cancellation or acceleration of any obligation
or  loss  of  any  material  benefit)  under  any of the  terms,  conditions  or
provisions of any note,  bond,  mortgage,  indenture,  lease,  contract or other
agreement,  instrument  or  obligation  to  which  the  Company  or  any  of its
Subsidiaries  is a party or  which  any of them or any of  their  properties  or
assets may be bound,  or (iii)  subject to  obtaining  the  Company  Shareholder
Approval  and  compliance  with the  requirements  set forth in Section  3.04(c)
below,  conflict  with or violate any permit,  concession,  franchise,  license,
judgment,  order, decree, statute, law, ordinance, rule or regulation applicable
to the Company or any of its  Subsidiaries or any of its or their  properties or
assets, except in the case of (ii) and (iii) for any such conflicts, violations,
defaults, terminations, cancellations or accelerations which, individually or in
the aggregate,  would not have a Material  Adverse Effect on the Company and its
Subsidiaries taken as a whole.

            (c) No   consent,  approval,   order   or    authorization   of,  or
registration,  declaration or filing with any Governmental Authority is required
by or with respect to the Company or any of its  Subsidiaries in connection with
the  execution and delivery of this  Agreement or the Stock Option  Agreement or
the consummation of the transactions  contemplated hereby or thereby, except for
(i) the filing of the  Articles of Merger  with the  Pennsylvania  Secretary  of
State, (ii) the filing of the Schedule 14D-9 with the SEC in accordance with the
Exchange Act, (iii) the filing of the Proxy Statement with the SEC in accordance
with the Exchange  Act, (iv) the filing of a premerger  notification  and report
form under the Hart-Scott-Rodino  Antitrust Improvements Act of 1976, as amended
(the "HSR  Act"),  and (v) such  consents,  approvals,  orders,  authorizations,
registrations,  declarations  and  filings as either (x) may be  required  under
applicable  state  securities  laws and the laws of any  foreign  country or (y)
which,  individually  or in the  aggregate,  would not reasonably be expected to
have a Material  Adverse Effect on the Company and its  Subsidiaries  taken as a
whole,  or would not reasonably be expected to impair the ability of the Company
to perform its obligations under this Agreement in any material respect.

      SECTION 3.05.     SEC Filings; Financial  Statements. (a) The  Company has
filed all forms,  reports and documents required to be filed by the Company with
the SEC since January 1, 1994  (collectively,  together with any forms,  reports
and documents  filed by the Company with the SEC after the date hereof until the
Closing, the "Company SEC Reports").  Each such report, when filed,  complied in
all  material  respects  with  the  requirements  of the  Exchange  Act  and the
applicable rules and regulations  thereunder and, as of their respective  dates,
none of such  reports  contained  any untrue  statement  of a  material  fact or
omitted to state a material fact  required to be 

                                       12
<PAGE>
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances under which they were made, not misleading.

            (b) Each of the consolidated  financial  statements  (including,  in
each case, any related notes)  contained in the Company SEC Reports  complied as
to form in all material  respects with the applicable  rules and  regulations of
the SEC with respect thereto, was prepared in accordance with generally accepted
accounting  principles  applied on a  consistent  basis  throughout  the periods
involved (except as may be indicated in the notes to such financial  statements)
and fairly presented the consolidated  financial position of the Company and its
Subsidiaries as at the respective  dates and the  consolidated  results of their
operations  and cash flows for the  periods  indicated,  except  that  unaudited
interim financial  statements  contained in any Company Quarterly Report on Form
10-Q (i) were or are subject to normal  year-end  adjustments  which were not or
are not  expected  to be material  in amount,  and (ii) do not contain  footnote
disclosure.  The  unaudited  balance sheet of the Company as of June 30, 1998 is
referred to herein as the "Company Balance Sheet."

      SECTION  3.06.     Indebtedness;  Absence of Undisclosed Liabilities.  (a)
Section  3.06  of the  Company  Disclosure  Schedule  sets  forth a list of each
instrument  which evidences  Indebtedness of the Company or any Subsidiary,  and
the aggregate  principal amount thereof  outstanding as of the date hereof.  The
total aggregate  principal amount  outstanding as of the date hereof of all such
Indebtedness  is  $189,945,  which  includes  $0 in face  amount of  outstanding
letters of credit. Except as set forth in Section 3.06 of the Company Disclosure
Schedule,  all of such  instruments are in full force and effect and neither the
Company, nor any Subsidiary (as the case may be) is in default thereunder,  nor,
to the  knowledge of the Company,  is any other party to any such  instrument in
default  thereunder,  nor to the  knowledge of the Company,  does any  condition
exist that, with the giving of notice or lapse of time or both, would constitute
a default thereunder, which default could reasonably be expected to give rise to
a  right  on the  part of some  party  thereto  to  terminate  such  instrument,
accelerate the obligations  thereunder or claim damages thereunder,  except such
default (i) as to which requisite waivers or consents have been obtained or (ii)
which is curable and is cured within the  applicable  period for cure  permitted
under such  instruments.  Section 3.06 of the Company  Disclosure  Schedule also
sets  forth a list  of each  other  instrument  or  agreement  that  contains  a
restriction,  limitation  or  encumbrance,  of any kind,  on the  ability of the
Company or any Subsidiary to pay dividends on its respective capital stock.

            (b) Section 3.06 of the Company Disclosure  Schedule also sets forth
all  contracts  and other  agreements  and  arrangements  pursuant  to which the
Company or any  Subsidiary  has agreed to indemnify  or  exonerate  any officer,
director or employee of the  Company or of any  Subsidiary  with  respect to any
matter.  Except as described in Section 3.06 of the Company Disclosure Schedule,
the Company has not received any written  notice of, and, to the best  knowledge
of the  Company,  there are no  circumstances  which  might  give  rise to,  any
obligation  or  liability  on the part of the  Company or any  Subsidiary  so to
indemnify any such officer, director or employee.

            (c) Except as  disclosed  in the Company SEC Reports  filed prior to
the date hereof, the Company and its Subsidiaries do not have any liabilities as
of the date hereof,  either accrued or contingent,  and whether due or to become
due that, under generally  accepted  accounting  

                                       13
<PAGE>
principles,  are required to be reflected in the Company's financial statements,
other than (i) liabilities  reflected or reserved against in the Company Balance
Sheet,  (ii)  liabilities  specifically  described in this Agreement,  or in the
Company Disclosure Schedule,  and (iii) normal or recurring liabilities incurred
since June 30,  1998 in the  ordinary  course of business  consistent  with past
practices and which are not,  individually or in the aggregate,  material to the
business, results,  operations,  financial condition or prospects of the Company
and its Subsidiaries, taken as a whole.

      SECTION  3.07.     Absence of Certain Changes or Events. Since the date of
the Company Balance Sheet, the Company and its Subsidiaries have conducted their
businesses  only in the  ordinary  course and in a manner  consistent  with past
practice  and,  since such  date,  there has not been (i) any  Material  Adverse
Effect with respect to the Company and its Subsidiaries,  taken as a whole, and,
to the  best  knowledge  of the  Company,  no fact  or  condition  exists  or is
threatened  which is reasonably  likely to cause a Material  Adverse Effect with
respect to the Company and its Subsidiaries, taken as a whole, in the future, or
(ii) any material change by the Company in its accounting methods, principles or
practices  except as  required  by  concurrent  changes  in  generally  accepted
accounting principles.

      SECTION   3.08.     Tax   Matters.   (a)  Each  of  the  Company  and  its
Subsidiaries has prepared and timely filed, and will file on a timely basis, all
material  federal,  state,  local and foreign  returns,  estimates,  information
statements and reports  ("Returns")  relating to any and all Taxes concerning or
attributable to the Company or its Subsidiaries or their operations and required
to be filed on or prior to the Effective Time.

            (b) Each  such  Return   was  true,  correct  and  complete  on  the
respective  date on which it was filed and, to the knowledge of the Company,  no
event has since occurred  requiring any amendment  thereto,  which amendment has
not been made in a manner such that each such Return  remains true,  correct and
complete.

            (c) The  Company as of the  Effective  Time:  (A) will have paid all
Taxes it is  required  to pay  prior  to the  Effective  Time and (B) will  have
withheld with respect to its employees all federal and state income taxes, FICA,
FUTA and other Taxes required to be withheld.

            (d) The  accounts  shown on the  Company  Balance  Sheet  (excluding
amounts  classified thereon as deferred) are sufficient for the discharge of all
Taxes attributable or with respect to all periods, or portions thereof, prior to
the date of the Company Balance Sheet remaining  unpaid as of such date,  except
as set forth in Section 3.08 of the Company Disclosure Schedule. There is no Tax
deficiency  outstanding  or assessed,  or to the Company's  knowledge  proposed,
against the Company or its Subsidiaries  that is not reflected as a liability on
the Company Balance Sheet nor has the Company executed any waiver of any statute
of  limitations  on or extending the period for the  assessment or collection of
any Tax. No tax audit or  examination  is now pending or  currently  in progress
with respect to the Company or its Subsidiaries.

            (e) The Company has not filed a consent under Section  341(f) of the
Code concerning collapsible corporations.  The Company has not made any payment,
nor is it obligated to make any payment, nor is it a party to any agreement that
under certain circumstances could obligate it to make any payment, that will not
be deductible  under  Sections  280G or 162(m) of the Code.  The Company has not
been (nor does it have any  liability  for unpaid  Taxes  because it once 

                                       14
<PAGE>
was) a member of an affiliated group (other than the current affiliated group of
the Company and its  Subsidiaries)  during any part of any  consolidated  return
year within any part of which consolidated return year any other corporation was
also a member of such  group.  The  Company  is not and has not been  during the
applicable  period  specified in Section  897(c)(1)(A)(ii)  of the Code a United
States real property holding  corporation as defined in Section 897(c)(2) of the
Code.  Without  taking  into  account  the  transactions  contemplated  by  this
Agreement,  including, without limitation, the Offer and the Merger, neither the
Company nor any of its Subsidiaries has any losses subject to the limitations of
Section 382 of the Code.


      SECTION  3.09.     Certain  Transactions;  Certain Payments. (a) Except as
set  forth in  Section  3.09 of the  Company  Disclosure  Schedule,  none of the
officers  or  directors  of the  Company or of any of its  Subsidiaries  nor any
Affiliate of the  Company,  and, to the  knowledge  of the Company,  none of the
employees of the Company or of any of its  Subsidiaries  is currently a party to
any  transaction  with the  Company or any of its  Subsidiaries  (other than for
services as an employee,  officer or director),  including,  without limitation,
any contract, agreement or other arrangement (i) providing for the furnishing of
services to or by, (ii) providing for rental of real or personal  property to or
from,  or (iii)  otherwise  requiring  payments  to or from,  any such  officer,
director,  Affiliate or employee,  any member of the family of any such officer,
director or employee or any corporation,  partnership,  trust or other entity in
which any such officer, director or employee has a substantial interest or which
is an Affiliate of such officer, director or employee.

            (b) Except as set forth in Section  3.09 of the  Company  Disclosure
Schedule,  none of the  officers  or  directors  of the Company or of any of its
Subsidiaries  nor any  Affiliate  of the  Company,  or, to the  knowledge of the
Company,  any other person or entity  associated with or acting for or on behalf
of the Company or any of its  Subsidiaries,  has directly or indirectly (i) made
any bribe,  payoff,  influence  payment  (other than payments made in accordance
with normal commercial practices), kickback or other unlawful gift or payment to
any person or entity,  private or public,  regardless of form, whether in money,
property or services (w) to obtain favorable treatment in securing business, (x)
to pay for  favorable  treatment  for business  secured,  (y) to obtain  special
concessions or for special  concessions  already obtained,  for or in respect of
the Company or any of its  Subsidiaries or Affiliates or (z) in violation of the
United  States  Foreign  Corrupt  Practices  Act or any  other  federal,  state,
territorial,  local  or  foreign  law,  statute,  rule  or  regulation  or  (ii)
established  or  maintained  any fund or asset that has not been recorded in the
books and records of the Company in connection with any of the matters described
in clause (i) above.

      SECTION  3.10.     Required  Authorizations.  Section 3.10 of  the Company
Disclosure  Schedule  sets  forth  a true  and  complete  list  of all  Required
Authorizations  which the Company or any of its Subsidiaries must give or obtain
for the execution and delivery of this  Agreement or the Stock Option  Agreement
by the Company or the  consummation by the Company or any of its Subsidiaries of
any of the transactions contemplated hereby or thereby or in order to enable all
the issued and  outstanding  capital  stock of the Company to be acquired in the
Offer or to be converted as contemplated by Article II.

<PAGE>
      SECTION  3.11.     Litigation.  Except as set forth in Section 3.11 of the
Company  Disclosure  Schedule or as  indicated in any of the Company SEC Reports
filed prior to the date hereof, there are no suits, litigations, investigations,
actions or  proceedings of any kind pending or (to the knowledge of the Company)
threatened  against the Company or any Subsidiary,  nor (to the knowledge of the
Company)  is any such matter  pending or  threatened  against any other  person,
which,  if  adversely  determined,  would have a Material  Adverse  Effect  with
respect to the Company and its Subsidiaries taken as a whole.

      SECTION  3.12.     Compliance with Law; Regulatory Compliance.  (a) Except
as set forth in Section 3.12 of the Company  Disclosure  Schedule and except for
instances of non-compliance which,  individually or in the aggregate,  would not
have a Material  Adverse Effect with respect to the Company and its Subsidiaries
taken as a whole, neither the Company nor any of its Subsidiaries is or has been
in violation of any applicable federal, state, provincial, local or foreign law,
regulation,  ordinance  or  other  requirement  of  any  Governmental  Authority
relating to it or to its securities,  property,  operations or business, and, to
the best  knowledge of the Company,  no event has occurred or condition or state
of facts exists that could give rise to any such violation.  Except as set forth
in Section  3.12 of the Company  Disclosure  Schedule,  there is no  outstanding
order, writ, judgment, stipulation,  injunction, decree, determination, award or
other order of any court or governmental agency or instrumentality,  domestic or
foreign, against or affecting the Company, any of its Subsidiaries or any of the
assets of the Company or its Subsidiaries.

            (b) The Company and its  Subsidiaries  possess,  or have made timely
application for, all Governmental  Approvals with and under all federal,  state,
provincial, local and foreign laws and Governmental Authorities, required by the
Company  and  its  Subsidiaries  to  carry  on any  substantial  part  of  their
respective businesses as presently conducted and to use and operate any of their
respective property and assets, other than Governmental  Approvals,  the absence
of which, individually or in the aggregate,  would not reasonably be expected to
have a Material Adverse Effect with respect to the Company and its Subsidiaries,
taken as a whole. All such  Governmental  Approvals are in full force and effect
and neither the Company nor any of its  Subsidiaries is in violation of any such
Governmental Approval or any other permit, license,  approval,  authorization or
registration  applicable to it or to the operation of its  respective  business,
other  than  violations  which,  individually  or in the  aggregate,  would  not
reasonably  be expected to have a Material  Adverse  Effect with  respect to the
Company and its Subsidiaries taken as a whole, and, to the best knowledge of the
Company, no event or condition or state of facts exists (or would exist upon the
giving  of  notice  or  lapse  of time or  both)  that  could  result  in such a
violation.  Except  as  disclosed  in  Section  3.12 of the  Company  Disclosure
Schedule,  the Company has no reason to believe that any pending application for
any such  Governmental  Approval will not be timely granted and no proceeding is
pending or, to the knowledge of the Company,  threatened  to revoke,  suspend or
materially  modify any  Governmental  Approval  possessed  by the Company or its
Subsidiaries or deny any renewal thereof.

            (c) Except as disclosed  in Section  3.12 of the Company  Disclosure
Schedule,  the Company and its Subsidiaries  have made all Governmental  Filings
required  to be  made  with  any  Governmental  Authority  with  respect  to the
operation  of their  respective  businesses  and the use and  operation of their
respective  properties and assets, other than Governmental  Filings, the 

                                       16
<PAGE>
absence of which,  individually  or in the  aggregate,  would not  reasonably be
expected to have a Material  Adverse  Effect with respect to the Company and its
Subsidiaries, taken as a whole.

      SECTION 3.13.     Contracts.  Set forth in Section  3.13  of  the  Company
Disclosure  Schedule is a list of (a) all  contracts,  agreements,  commitments,
undertakings or obligations to which the Company or any of its Subsidiaries is a
party or by which it or its  assets or  properties  are bound or  subject  which
involve the payment by or to the Company or any of its Subsidiaries of more than
$50,000 under any one of such  contracts and which have a remaining term of more
than 120 days (taking into account the effect of any renewal  options),  (b) all
contracts,  agreements or other  instruments  evidencing  Indebtedness;  (c) all
joint venture or  partnership  agreements to which the Company or any Subsidiary
is a party; (d) all contracts or agreements  restricting the right of any person
or entity to compete with the Company or any  Subsidiary,  and all  contracts or
agreements  restricting  the right of the Company or any  Subsidiary  to compete
with any person or entity,  to sell to or purchase  from any person or entity or
to hire any person;  (e) all contracts or  agreements,  other than  contracts or
agreements  for  the  sale of  products  in the  ordinary  course  of  business,
providing for  indemnification  or  exoneration of any other person or entity by
the Company or any  Subsidiary;  (f) all contracts or agreements with any public
utility  pursuant  to which the  Company  or any  Subsidiary  provides  goods or
services to such public utility; (g) all contracts pursuant to which the Company
provides  services and pursuant to which there is no limitation on the liability
of  the  Company;  and  (h)  all  other  contracts,   agreements,   commitments,
undertakings or obligations to which the Company or any of its Subsidiaries is a
party or by which it or its assets or  properties  are bound or  subject  (other

Benefit  Plans) (x) which if  terminated  or lost would have a Material  Adverse
Effect with respect to the Company and its  Subsidiaries,  taken as a whole,  or

"Contracts").  There have been made available to Crane true and complete  copies
of all such Contracts that are in writing (including all amendments  thereto, if
any).  Except as set forth in Section 3.13 of the Company  Disclosure  Schedule,
all of the  Contracts  are in full force and effect and  neither the Company nor
any of its Subsidiaries (as the case may be) is in default  thereunder,  nor, to
the  knowledge  of the  Company,  is any other party to any  Contract in default
thereunder,  nor, to the best of the  Company's  knowledge,  does any  condition
exist that, with the giving of notice or lapse of time or both, would constitute
a default  thereunder,  which  default would give rise to a right on the part of
some party  thereto to  terminate  such  Contract or claim  damages  thereunder,
except such  default  (i) as to which  requisite  waivers or consents  have been
obtained or (ii) which is curable and is cured within the applicable  period for
cure permitted  under such Contract.  Except as set forth in Section 3.10 of the
Company Disclosure  Schedule,  no approval or consent of any person is needed in
order for the  Contracts  to  continue  in full force and effect  under the same
terms and  conditions  currently in effect  following  the  consummation  of the
transactions contemplated by this Agreement.

      SECTION 3.14.     Real  Property.  None  of  the  Company  or  any  of its
Subsidiaries  owns any real  property.  Section  3.14 of the Company  Disclosure
Schedule  sets forth a list (by  lessee)  and  summary  description  of all Real
Property  Leases.  The  Company and each  Subsidiary  (as the case may be) has a
valid  leasehold  interest in each Real Property Lease held by it as of the date
of this  Agreement,  in each case free and clear of all  Liens,  except  for the
Silicon  Valley Bank Liens.  The Company has made  available to Crane a true and
complete  copy of each Real  Property  Lease  which is in  writing.  Neither the
Company nor any of its  Subsidiaries is a party to or holds property  subject to
any Real Property Lease which is not in writing. The Real Property Leases are 

                                       17
<PAGE>
in full force and effect and neither the Company nor any of its Subsidiaries (as
the case may be) has received any written notice of default thereunder which has
not been remedied or waived. Each Real Property Lease was negotiated on an arm's
length basis.  Neither the Company nor any of its  Subsidiaries has received any
written notice or has any knowledge of any pending,  threatened or  contemplated
condemnation proceeding or assessment for public improvements affecting any real
property  leased pursuant to a Real Property Lease or any part thereof or of any
sale or other disposition thereof in lieu of condemnation.

      SECTION   3.15.     Personal   Property.   The   Company  or  one  of  its
Subsidiaries  (as the case may be) owns all Personal  Property owned by it as of
the date of this  Agreement,  whether or not  reflected  in the Company  Balance
Sheet,  in each case free and clear of all Liens,  except for the Silicon Valley
Bank Liens.  Section 3.15 of the Company  Disclosure  Schedule also sets forth a
list (by lessee or licensee) and a summary  description of all Personal Property
Leases.  The Company or one of its Subsidiaries (as the case may be) has a valid
leasehold  interest in each Personal Property Lease held by it as of the date of
this Agreement,  in each case free and clear of all Liens except for the Silicon
Valley  Bank  Liens.  All of the  Personal  Property  owned or  leased  by,  and
currently  used or necessary for or in the  operations of, the Company or any of
its Subsidiaries,  taken as a whole, is in good operating  condition and repair,
ordinary wear and tear excepted.

      SECTION  3.16.     Intellectual  Property  Rights.  Except as set forth on
Section 3.16 of the Company Disclosure Schedule:

            (a) the  Company  and   each  of its  Subsidiaries  owns  or has the
exclusive, perpetual, royalty-free right to use all Intellectual Property Rights
that are used in connection  with the  operation of its business  (collectively,
the  "Requisite  Rights"),  free and clear of all Liens  other than the  Silicon
Valley Bank Liens;

            (b) to the knowledge of the Company, no product or service licensed,
marketed or sold by the Company or any of its Subsidiaries  violates any license
or  infringes  any  Intellectual  Property  Rights  of  others  and no person is
infringing upon or has misappropriated any Requisite Rights.

            (c) there  is  no  pending  or,  to the  knowledge  of the  Company,
threatened  claim or litigation  against the Company or any of its  Subsidiaries
contesting  the validity of or right to use the  Requisite  Rights,  nor has the
Company or any of its  Subsidiaries  received any written notice that any of the
Requisite Rights or the operation of their respective  businesses conflicts with
the  asserted  rights of  others,  in any case,  which,  individually  or in the
aggregate,  if  adversely  determined  against  the  Company  or the  applicable
Subsidiary  would  reasonably be expected to have a Material Adverse Effect with
respect to the Company and its Subsidiaries, taken as a whole.

As used herein, the term  "Intellectual  Property Rights" means all intellectual
property rights, including, without limitation, Proprietary Technology, patents,
patent applications,  patent rights, trademarks,  trademark applications,  trade

      SECTION  3.17.     Environmental  Matters. (a) The Company and each of its
Subsidiaries has applied for and has in effect all federal,  state and local and
foreign   governmental   approvals,   authorizations,   certificates,   filings,
franchises,  licenses,  notices,  permits and rights  ("Environmental  Permits")
under applicable statutes, laws, ordinances, rules, orders and regulations which
are  administered,  interpreted  or enforced by a  Governmental  Authority  with
jurisdiction  over  pollution or  protection of the  environment  (collectively,
"Environmental  Laws")  necessary  for  it to  carry  on  its  business  as  now
conducted,  and there  has  occurred  no  default  under any such  Environmental
Permit,  except for the lack of  Environmental  Permits and for  defaults  under
Environmental  Permits  that,  individually  or  in  the  aggregate,  would  not
reasonably  be expected to have a Material  Adverse  Effect with  respect to the
Company and its Subsidiaries taken as a whole.


            (b) The Company and each of its  Subsidiaries  is, and has been,  in
compliance with applicable  Environmental  Laws except for instances of possible
noncompliance which,  individually or in the aggregate,  would not reasonably be
expected to have a Material  Adverse  Effect with respect to the Company and its
Subsidiaries taken as a whole.

            (c) There is no suit,  action,  proceeding or inquiry pending or, to
the Company's knowledge,  threatened before any Governmental  Authority in which
the Company or any or its Subsidiaries has been or, to the best knowledge of the
Company with respect to threatened suits, actions and proceedings,  may be named
as a defendant (i) for alleged noncompliance (including by any predecessor) with
any  Environmental  Law or (ii) relating to the release into the  environment of
any  Hazardous  Material (as  hereinafter  defined),  asbestos,  polychlorinated
biphenyls  or oil,  whether or not  occurring  at, on, under or involving a site
owned,  leased or operated by the Company or any of its  Subsidiaries,  or (iii)
for any site or location for which it or its Subsidiaries has been designated as
a  potentially  responsible  party under any  federal,  state,  local or foreign
superfund law, or (iv) for any claim for damages to natural resources, except in
the cases of  clauses  (i)  through  (iv)  above for any such  suits,  actions,,
proceedings  and inquiries  that,  individually  or in the aggregate,  would not
reasonably  be expected to have a Material  Adverse  Effect with  respect to the
Company and its Subsidiaries taken as a whole.

            (d) During the period of  ownership  or operation by the Company and
its  current  or  former  Subsidiaries  of any of their  respective  current  or
formerly owned properties, there have been no underground storage tanks (whether
currently  active or not) and no  polychlorinated  biphenyls in  transformers or
other electrical equipment and there have been no releases of Hazardous Material
or of asbestos, polychlorinated biphenyls or oil in, on, under or affecting such


                                       19
<PAGE>
properties or, to the Company's  knowledge,  any  surrounding  site,  except for
those that, individually or in the aggregate would not reasonably be expected to
have a Material  Adverse Effect with respect to the Company and its Subsidiaries
taken as a whole.  Prior to the period of  ownership or operation by the Company
or its  current or former  Subsidiaries  of any of their  respective  current or
formerly owned properties, to the Company's knowledge, there were no releases of
Hazardous  Material  or  asbestos,  polychlorinated  biphenyls  or oil or  other
petroleum  products  in,  on,  under  or  affecting  any  such  property  or any
surrounding site, except for those that, individually or in the aggregate, would
not reasonably be expected to have a Material Adverse Effect with respect to the
Company and its Subsidiaries  taken as a whole.  "Hazardous  Material" means any
pollutant,  contaminant,  or  hazardous  substance  within  the  meaning  of the
Comprehensive  Environmental  Response,  Compensation and Liability Act or other
applicable Environmental Laws.

            (e) The Company and each of its Subsidiaries  have all Environmental
Permits required in connection with the use,  storage,  handling and disposal of
radioactive materials,  and have complied and are in current compliance with all
applicable  federal,  state,  local  and  foreign  laws in  connection  with the

      SECTION 3.18.     Products  Liability. Other than ordinary course warranty

damage or other loss as a result of product defects that exceed, with respect to
any one type or class of defect, $25,000 in the aggregate.

      SECTION 3.19.     Insurance.  The Company and each of its Subsidiaries has
in effect valid and effective policies of insurance (true and complete copies of
which have been provided to Crane),  issued by companies believed by the Company
to be sound and reputable,  insuring the Company or such Subsidiary (as the case
may be) for losses  customarily  insured  against  by others  engaged in similar
lines of  business.  To the best  knowledge of the  Company,  such  policies are
reasonable,  in both scope and amount,  in light of the risks  attendant  to the
businesses  conducted by the Company and its  Subsidiaries.  Neither the Company
nor any of its Subsidiaries will have any liability after the Effective Time for
retrospective or retroactive premium  adjustments.  The Company has delivered to
Crane true and complete  copies of lists  furnished by the  Company's  insurance
brokers  identifying the names of any third party named as an additional insured
under any insurance policy  maintained by the Company or any of its Subsidiaries
since 1994. Section 3.19 of the Company  Disclosure  Schedule also discloses the

terms  of his or her  severance  or  other  payments  upon  termination  of such

to Crane true and complete  copies of all Employment  Agreements,  together with
all amendments  thereto (if any).  

                                       20
<PAGE>
Since  the date of the  Company  Balance  Sheet,  neither  the  Company  nor any
Subsidiary has (i) except as set forth in Section 3.20 of the Company Disclosure
Schedule,  effected any increase in salary,  wage or other  compensation  of any
kind, whether current or deferred, to any officer,  director,  employee,  agent,
broker or  consultant in excess of five percent of the  compensation  payable to
any such  person  or (ii)  made any  contribution  to any  trust or plan for the
benefit of employees  except for  contributions  made in the normal and ordinary
course of business in a manner  consistent with past practices or as required by
the terms thereof as now in effect.

            (b) Except as set forth in Section  3.20 of the  Company  Disclosure
Schedule or as disclosed  in the Company SEC Reports  filed prior to the date of
this  Agreement,  and except as  provided  for in this  Agreement,  neither  the
Company  nor any of its  Subsidiaries  is a party  to any  oral or  written  (i)
agreement  with any  officer or other key  employee of the Company or any of its

of the nature  contemplated by this Agreement or (B) providing for  compensation
payments  that would not be  deductible  by the Company  for federal  income tax
purposes,  (ii)  agreement with any officer or other key employee of the Company
or any of its  Subsidiaries  providing any  compensation  guarantee in excess of
$50,000 per annum,  or (iii)  agreement or Benefit Plan,  any of the benefits of
which  will be  increased,  or the  vesting  of the  benefits  of which  will be
accelerated,  by the occurrence of any of the transactions  contemplated by this
Agreement or the value of any of the benefits of which will be calculated on the
basis of any of the transactions contemplated by this Agreement.

      SECTION 3.21.     Labor Relations.  To the best knowledge of the  Company,
relations of the Company and each of its  Subsidiaries  with their employees are
good. Except as disclosed on Section 3.21 of the Company Disclosure Schedule, no
employee of the Company or any of its  Subsidiaries  is represented by any union
or other labor organization. No representation election, arbitration proceeding,
grievance, labor strike, dispute,  slowdown,  stoppage or other labor trouble is
pending or, to the knowledge of the Company, threatened,  against the Company or
any  of  its  Subsidiaries.  No  complaint  against  the  Company  or any of its
Subsidiaries is pending or, to the knowledge of the Company,  threatened  before
the National Labor Relations Board, the Equal Employment  Opportunity Commission
or any similar  state or local  agency,  by or on behalf of any  employee of the
Company or any of its Subsidiaries.

      SECTION 3.22.     Employee Benefit Plans. (a) The Company has set forth on
Section 3.22 of the Company  Disclosure  Schedule a list of all employee benefit
plans (as defined in Section 3(3) of ERISA) and all bonus,  stock option,  stock
purchase,  fringe  benefits,  incentive,  deferred  compensation,   supplemental
retirement, post-retirement health or welfare plan, severance and other employee
benefit plans and arrangements,  written or otherwise, maintained by the Company
or any trade or  business  (whether  or not  incorporated)  which is a member or
which is under common control with the Company (an "ERISA Affiliate") within the
meaning of Section  414 of the Code,  or any  Subsidiary  of the Company for the
benefit of, or relating to, any current or former  employee of the Company or an
ERISA  Affiliate  (together,  the "Company  Group") or with respect to which the
Company  or an  ERISA  Affiliate  may have  liability  (together,  the  "Benefit
Plans").

            (b) With  respect  to  each  Benefit  Plan,  the  Company  has  made
available to Crane a true and correct copy of (i) the most recent  annual report
(Form 5500) filed with the 

                                       21
<PAGE>
Internal Revenue Service  ("IRS"),  (ii) such Benefit Plan (or in the case of an
unwritten Benefit Plan, a written summary  thereof),  (iii) each trust agreement
and group annuity  contract,  if any, relating to such Benefit Plan and (iv) the
most recent actuarial report or valuation  relating to a Benefit Plan subject to
Title IV of ERISA.

            (c) Each of the  Benefit  Plans and all  related  trusts,  insurance
contracts and funds have been created,  maintained,  funded and  administered in
all respects in compliance  with all applicable  laws and in compliance with the
plan document,  trust agreement,  insurance policy or other writing creating the
same or applicable  thereto. No Benefit Plan is or, to the best knowledge of the
Company, is proposed to be under audit or investigation,  and no completed audit
of any Benefit Plan has resulted in the imposition of any tax, fine or penalty.

            (d) No prohibited  transaction (within the meaning of Section 406 of
ERISA and Section  4975 of the Code) with  respect to any Benefit Plan exists or
has occurred that could subject any member of the Company Group to any liability
or tax under Part 5 of Title I of ERISA or Section  4975 of the Code.  No member
of the Company Group,  nor any  administrator  or fiduciary of any Benefit Plan,
nor any agent of any of the foregoing,  has engaged in any  transaction or acted
or failed to act in a manner that will  subject any member of the Company  Group
to any  liability  for a breach of  fiduciary  or other duty under  ERISA or any
other applicable law. With the exception of the requirements of Section 4980B of
the Code, no  post-retirement  benefits are provided under any Benefit Plan that
is a welfare benefit plan as described in ERISA Section 3(1).

            (e) Section 3.22 of the Company  Disclosure  Schedule discloses each
Benefit Plan that purports to be a qualified  plan under  Section  401(a) of the
Code and exempt from United States  federal  income tax under Section  501(a) of
the  Code  (a  "Qualified  Plan").  With  respect  to  each  Qualified  Plan,  a
determination letter (or opinion or notification letter, if applicable) has been
received from the IRS that such plan is qualified  under  Section  401(a) of the
Code and exempt from federal  income tax under  Section  501(a) of the Code.  No
Qualified  Plan has been  amended  since the date of the most recent such letter
applicable  to such  Qualified  Plan.  No member of the Company  Group,  nor any
fiduciary of any  Qualified  Plan,  nor any agent of any of the  foregoing,  has
taken any action that would adversely affect the qualified status of a Qualified
Plan or the qualified status of any related trust.

            (f) No Benefit Plan is a defined  benefit plan within the meaning of
Section  3(35) of ERISA (a "Defined  Benefit  Plan").  No Defined  Benefit  Plan
sponsored or maintained  by any member of the Company Group has been  terminated
or  partially  terminated  except as set forth on  Section  3.22 of the  Company
Disclosure  Schedule.  Each Defined  Benefit Plan  identified  as  terminated on
Section  3.22 of the Company  Disclosure  Schedule has met the  requirement  for
standard  termination of  single-employer  plans contained in Section 4041(b) of
ERISA.  During the five-year  period ending at the Effective  Time, no member of
the Company Group has transferred a Defined  Benefit Plan to a corporation  that
was not, at the time of  transfer,  related to the  transferor  as  described in
Section 414 of the Code.

            (g) No Benefit  Plan is a  multiemployer  plan within the meaning of
Section 3(37) or Section 4001(a)(3) of ERISA (a "Multiemployer Plan"). No member
of the Company Group has withdrawn from any  Multiemployer  Plan or incurred any
withdrawal  liability to or under 


                                       22
<PAGE>
any  Multiemployer  Plan.  No Benefit Plan covers any employees of any member of
the Company Group in any foreign country or territory.

            (h) With  respect  to the  Benefit  Plans,  individually  and in the
aggregate,  there are no funded benefit obligations for which contributions have
not been made or properly accrued and there are no unfunded benefit  obligations
which have not been accounted for by reserves,  or otherwise  properly footnoted
in accordance with generally accepted  accounting  principles,  on the financial
statements of the Company.

      SECTION 3.23.      No Existing  Discussions.  As of  the date  hereof, the
Company  is  not  engaged,   directly  or  indirectly,  in  any  discussions  or
negotiations with any other party with respect to an Acquisition Proposal.

      SECTION  3.24.     Information Supplied.  None of the written  information
supplied  or to be  supplied  by  the  Company  specifically  for  inclusion  or
incorporation  by reference in the Offer  Documents or the Proxy Statement will,
at the  respective  times  filed  with  the SEC and,  in the  case of the  Proxy
Statement,  the date it is first mailed to the Company's  shareholders or at the
time of the Company  Shareholders  Meeting,  contain any untrue  statement  of a
material fact or omit to state any material  fact required to be stated  therein
or  necessary  in  order  to  make  the  statements  therein,  in  light  of the
circumstances  under which they are made, not  misleading.  The Proxy  Statement
will comply as to form in all material  respects  with the  requirements  of the
Exchange  Act  and  the  rules  and  regulations  thereunder,   except  that  no
representation  or warranty is made by the Company  with  respect to  statements

reason of the  execution of this  Agreement,  the Stock Option  Agreement or the
Shareholder  Agreements,  or the  consummation  of the Offer,  the Merger or the
other transactions contemplated by this Agreement, the Stock Option Agreement or
the Shareholder Agreements.

      SECTION 3.28.     Brokers. No broker, investment banker, financial advisor
or other  person,  other than Legg Mason Wood Walker,  Inc.,  is entitled to any
broker's,  finder's,  financial  advisor's or other similar fee or commission in

      SECTION 3.29.     Disclosure. No representation or warranty of the Company
in  this  Agreement  or  any  certificate,   schedule,  statement,  document  or

connection herewith, contains or will contain any untrue statement of a material
fact or omits or will omit to state a material fact required to be stated herein
or therein or necessary to make any statement herein or therein not misleading.

business and is in good standing (with respect to jurisdictions  which recognize
such  concept) in each  jurisdiction  in which the nature of its business or the
ownership or leasing of its  properties  makes such  qualification  or licensing
necessary, other than in such jurisdictions where the failure to be so qualified
or licensed or to be in good standing individually or in the aggregate would not
have a Material Adverse Effect on Crane and its Subsidiaries taken as a whole.

      SECTION  4.02.     Authority;  Noncontravention.  Each  of  Crane  and the
Purchaser  has all  requisite  corporate  power and authority to enter into this

delivered  by Crane  and the  Purchaser  and  constitutes  a valid  and  binding
obligation of each of Crane and the Purchaser, enforceable against Crane and the
Purchaser  in  accordance  with its terms  except as limited  by (i)  applicable
bankruptcy,  insolvency,  reorganization,  moratorium  and other laws of general
application  affecting  enforcement  of  creditors'  rights  generally  and (ii)
general principles of equity,  regardless of whether asserted in a proceeding in
equity or at law. The execution  and delivery of this  Agreement do not, and the

with the  provisions  of this  Agreement  by Crane and the  Purchaser  will not,
conflict with, or result in any violation of, or default (with or without notice
or lapse  of  time,  or both)  under,  or give  rise to a right of  termination,
cancellation or acceleration of any obligation or to loss of a material  benefit
under,  or result in the  creation  of any Lien  upon any of the  properties  or
assets of Crane or the  Purchaser  under,  (i) the  Certificate  or  Articles of
Incorporation  or  By-laws  of Crane or the  Purchaser,  (ii) any loan or credit
agreement,   note,  bond,  mortgage,   indenture,   lease  or  other  agreement,
instrument, permit, concession,  franchise or license applicable to Crane or the
Purchaser  or their  respective  properties  or assets or (iii)  subject  to the
governmental  filings and other matters  referred to in the following  sentence,
any  judgment,  order,  decree,  statute,  law,  ordinance,  rule or  regulation
applicable to Crane or the Purchaser or their  respective  properties or assets,
other  than,  in the  case of  clauses  (ii)  and  (iii),  any  such  conflicts,
violations,  defaults,  rights,  losses  or Liens  that  individually  or in the
aggregate  would  not (x)  have a  Material  Adverse  Effect  on  Crane  and its
Subsidiaries,  taken as a whole,  (y) impair the ability of Crane to perform its
obligations  under this  Agreement  in any  material  respect or (z)  prevent or
materially  delay the  consummation of any of the  transactions  contemplated by
this  Agreement.   No  consent,   approval,   order  or  authorization   of,  or
registration, declaration or filing with, any Governmental Authority is required
by or with respect to Crane or the  Purchaser in  connection  with the execution
and delivery of this Agreement by Crane or the Purchaser or the  consummation by
Crane or the  Purchaser  of the  transactions  contemplated  by this  Agreement,
except for (1) the filing of a premerger  notification and report form under the
HSR Act;  (2) the filing with the SEC of the Offer  Documents  and such  reports
under  Section  13(a),  13(d),  15(d)  or 16(a)  of the  Exchange  Act as may be
required in connection  with this Agreement,  the Stock Option  Agreement or the

Crane or the Purchaser to perform its  obligations  under this  Agreement in any
material respect.

      SECTION  4.03.     Information  Supplied.  None of the written information
supplied or to be supplied by Crane or the Purchaser  specifically for inclusion
or  incorporation  by reference in the Schedule 14D-9 or in the Proxy  Statement
will, at the  respective  times filed with the SEC and, in the case of the Proxy
Statement,  at the date it or any amendment or  supplement  thereto is mailed to
Company  shareholders  and at the  date  of the  Company  Shareholders  Meeting,
contain any untrue  statement  of a material  fact or omit to state any material
fact required to be stated 

                                       25
<PAGE>
therein  or  necessary  to  make  the  statements   therein,  in  light  of  the
circumstances  under  which  they were  made,  not  misleading,  except  that no
representation  or warranty is made by Crane or the  Purchaser  with  respect to
statements  made or  incorporated  by  reference  therein  based on  information
supplied by the Company specifically for inclusion or incorporation by reference
therein.

      SECTION 4.04.     Share   Ownership.   Without   giving   effect  to   the
transactions  contemplated by this Agreement, the Stock Option Agreement and the
Shareholder  Agreements,  neither  Crane  nor the  Purchaser  is an  "interested
shareholder"  for purposes of Section 2538 or  Subchapter F of Chapter 25 of the
PBCL.


                                    ARTICLE V
                                    COVENANTS

such Taxes and the Company maintains appropriate reserves with respect thereto;

                  (viii) not settle any tax claim  against the Company or any of
its  Subsidiaries  or any litigation (net of applicable  insurance  proceeds) in
excess of $10,000;

provided, however, that if the Company requests in writing that Crane consent to
the taking of any  affirmative  action on the part of the  Company the taking of
which  would  require  such  consent  pursuant to this  Section  5.01(a) and the
failure to grant such consent  within four  business days of receipt by Crane of
such request is the sole cause of the occurrence of a Material  Adverse  Effect,
then such Material Adverse Effect shall not be an Event for purposes of Annex II
nor shall Crane be  permitted  to  terminate  this  Agreement  solely due to the
occurrence of such Material Adverse Effect.

            (b) Other  Actions.  The Company shall not, and shall not permit any
of its  Subsidiaries to, take any action that would, or that could reasonably be
expected to, result in (i) any of its  representations  and warranties set forth
in this Agreement that are qualified as to materiality becoming untrue, (ii) any
of its  representations and warranties that are not so 

                                       28
<PAGE>
qualified  becoming  untrue in any  material  respect  or (iii)  subject  to the
Company's  rights  under  Section  5.02  and  Article  VII  hereof,  any  of the
conditions  to the Merger set forth in Article VI that are within the  Company's
control not being satisfied.

            (c) Advice of  Changes.  The Company  shall  promptly  advise  Crane
orally and in writing of (i) any representation or warranty made by it contained
in this  Agreement  that is  qualified  as to  materiality  becoming  untrue  or
inaccurate in any respect or any such  representation or warranty that is not so
qualified  becoming  untrue or  inaccurate  in any  material  respect,  (ii) the
failure by it to comply with or satisfy in any  material  respect any  covenant,
condition  or  agreement  to be  complied  with or  satisfied  by it under  this
Agreement  or (iii) any change or event  having,  or which could  reasonably  be
expected to have, a Material  Adverse Effect on the Company and its Subsidiaries
taken as a whole or on the truth of its  representations  and  warranties or the
ability of the  conditions  set forth in Article VI to be  satisfied.  Upon such
notification,  Crane and the Purchaser shall have the option to either terminate
this  Agreement  or to waive  any  right to  consider  any of the  foregoing  in
connection  with a  determination  as to whether any of the Events  specified in
subparagraphs (c), (f) or (g) of Annex II has occurred.

      SECTION 5.02.     No Solicitation. (a) The Company shall not, nor shall it
permit any of its  Subsidiaries  to, nor shall it authorize or permit any of its
directors,  officers or employees or any investment  banker,  financial advisor,
attorney,  accountant  or  other  representative  retained  by it or  any of its
Subsidiaries to, directly or indirectly  through another person,  (i) solicit or
initiate (including by way of furnishing information),  or take any other action
to facilitate,  any inquiries or the making of any proposal that  constitutes an
Acquisition  Proposal (as defined below) or (ii)  participate in any discussions
or negotiations regarding any Acquisition Proposal;  provided, however, that if,
at any time prior to the  acceptance  for  payment  of shares of Company  Common
Stock pursuant to the Offer, the Board of Directors of the Company determines in
good  faith,  based  upon the  advice of  outside  counsel  (including,  for all
purposes of this  Agreement,  Pepper Hamilton LLP), that it is required to do so
in order to comply with its fiduciary duties to the Company's shareholders under
applicable law, the Company may, in response to an Acquisition Proposal that was
not solicited by it, and subject to compliance with Section 5.02(c), (x) furnish
information  with  respect to the  Company  and its  Subsidiaries  to any person
pursuant to a customary  confidentiality agreement (as determined by the Company
after consultation with its outside counsel) and (y) participate in negotiations
regarding  such   Acquisition   Proposal.   For  purposes  of  this   Agreement,
"Acquisition  Proposal" means any inquiry,  proposal or offer from any person or
entity relating to any direct or indirect acquisition or purchase of 20% or more
of the assets of the Company and its Subsidiaries or 20% or more of any class of
equity securities of the Company or any of its Subsidiaries, any tender offer or
exchange  offer that if  consummated  would  result in any  person  beneficially
owning 20% or more of any class of equity  securities  of the  Company or any of
its Subsidiaries,  or any merger,  consolidation,  business  combination,  share
exchange,  recapitalization,  liquidation,  dissolution  or similar  transaction
involving the Company or any of its  Subsidiaries,  other than the  transactions
contemplated by this Agreement.

            (b) Except as expressly  permitted by this Section 5.02, neither the
Board of Directors of the Company nor any  committee  thereof shall (i) (unless,
prior to the  acceptance  for payment of shares of Company Common Stock pursuant
to the Offer,  it  determines  in good  faith,  

                                       29
<PAGE>
based upon the advice of outside counsel,  that it is required to do so in order
to  comply  with  its  fiduciary  duties  to the  Company's  shareholders  under
applicable law) withdraw or modify,  or propose  publicly to withdraw or modify,
in a manner adverse to Crane,  the approval or  recommendation  by such Board of
Directors or such committee of the Offer (including by amendment of the Schedule
14D-9),  the Merger or this  Agreement,  (ii) approve or  recommend,  or propose
publicly to approve or recommend,  any  Acquisition  Proposal or (iii) cause the
Company to enter into any letter of intent, agreement in principle,  acquisition
agreement or other similar agreement (each, an "Acquisition  Agreement") related
to any Acquisition  Proposal.  Notwithstanding the foregoing,  in the event that
prior to the  acceptance  for payment of shares of Company Common Stock pursuant
to the Offer the Company  receives a Superior  Proposal (as defined below),  the
Board of Directors  of the Company may (if it  determines  in good faith,  based
upon the advice of outside  counsel,  that it is  required  to do so in order to
comply with its fiduciary duties to the Company's  shareholders under applicable
law) (x) withdraw or modify its  approval or  recommendation  of the Offer,  the
Merger or this Agreement or (y) approve or recommend such Superior  Proposal and
terminate this Agreement (and concurrently with or after such termination, if it
so  chooses,  cause the  Company to enter  into an  Acquisition  Agreement  with
respect  to any  Superior  Proposal)  but only at a time that is after the third
business  day  following  Crane's  receipt of written  notice  from the  Company
advising  Crane  that the Board of  Directors  of the  Company  has  received  a
Superior Proposal, specifying the terms and conditions of such Superior Proposal
and identifying the person making such Superior  Proposal.  For purposes of this
Agreement,  a "Superior  Proposal"  means any  proposal or offer made by a third
party to acquire,  directly or indirectly,  for consideration consisting of cash
and/or  securities,  more than 50% of the combined voting power of the shares of
Company Common Stock then outstanding or a substantial  portion of the assets of
the  Company  and its  subsidiaries  and  otherwise  on terms which the Board of
Directors of the Company  determines in its good faith judgment,  based upon the
advice  of its  financial  advisors,  to be  more  favorable  to  the  Company's
shareholders than the Offer and the Merger and for which financing is either not
a contingency, or, if a contingency, is then committed and available.

            (c) In  addition  to the  obligations  of the  Company  set forth in
paragraphs  (a) and (b) of this Section  5.02,  the Company shall as promptly as
practicable  advise Crane of any  Acquisition  Proposal,  the material terms and
conditions  of such  Acquisition  Proposal and the identity of the person making
such request or  Acquisition  Proposal.  The Company will keep Crane  reasonably
informed  of  the  status  and  details  (including   amendments)  of  any  such
Acquisition Proposal.

            (d) Nothing  contained  in this  Section  5.02  shall  prohibit  the
Company from taking and disclosing to its  shareholders a position  contemplated
by  Rule  14e-2(a)  promulgated  under  the  Exchange  Act or  from  making  any
disclosure to the Company's  shareholders  if, in the good faith judgment of the
Board of Directors  of the Company,  after  consultation  with outside  counsel,
failure so to disclose would be  inconsistent  with its fiduciary  duties to the
Company's shareholders under applicable law; provided, however, that neither the
Company nor its Board of Directors nor any committee  thereof  shall,  except as
permitted  by Section  5.02(b),  withdraw  or modify,  or  propose  publicly  to
withdraw or modify,  its position with respect to this Agreement or the Offer or
the Merger or approve or recommend, or propose publicly to approve or recommend,
an Acquisition Proposal.

      SECTION  5.03.     Access to Information;  Confidentiality.  During normal
business hours during the period prior to the earlier of the termination of this
Agreement and the Effective Time, upon reasonable notice, the Company shall (and
shall  cause  its  Subsidiaries  to)  (i)  afford  to the  officers,  employees,
accountants,  counsel and other  representatives  of Crane,  access,  to all its
properties,  books,  contracts,   commitments,   records,  officers,  employees,
accountants,  accountants'  work papers,  correspondence  and affairs,  and (ii)
cause its and  their  officers  and  employees  to  furnish,  to Crane,  and its
authorized representatives,  any and all financial, technical and operating data
and other  information  pertaining  to the  businesses  of the  Company  and its
Subsidiaries as Crane shall from time to time reasonably  request.  In addition,
without  limiting the  generality of the  foregoing,  the Company will, and will
cause each of its  Subsidiaries to make available to Crane for examination  true
and  complete  copies  of  all  Returns  filed  by  the  Company  or  any of its
Subsidiaries,  together with all available  revenue agents'  reports,  all other
reports,  notices and  correspondence  concerning tax audits or examinations and
analyses of all provisions for reserves or accruals of taxes, including deferred
taxes.

      SECTION  5.04.     Required  Authorizations.  (a)  Crane,  Merger Sub and,
subject to Section 5.02 of this Agreement, the Company, shall each, and, subject
to  Section  5.02  of  this  Agreement,  the  Company  shall  cause  each of its
Subsidiaries  to,  as  promptly  as  practicable,  take all  reasonable  actions
necessary to obtain all Required Authorizations (if any) required to be given or
obtained by it,  respectively,  to permit Crane and Merger Sub, on the one hand,
and the Company,  on the other, to consummate the  transactions  contemplated by
this  Agreement  and the Stock Option  Agreement  and to realize the  respective
benefits to each party  contemplated  hereby and  thereby;  provided  that Crane
shall not be required to take any action to comply with any legal requirement or
agree to the  imposition of any order of any  Governmental  Authority that would
(i) prohibit or restrict  the  ownership or operation by Crane of any portion of
the  business  or assets  of Crane or the  Company  (or any of their  respective
Subsidiaries),  (ii) compel  Crane or the  Company  (or any of their  respective
Subsidiaries) to dispose of or hold separate any portion of its or the Company's
business or assets,  or (iii) impose any  limitation  on the ability of Crane or
the Surviving  Corporation or any of their respective affiliates or Subsidiaries
to  own  or  operate  the  business  and  operations  of  the  Company  and  its
Subsidiaries,  and provided further that the Company and its Subsidiaries  shall
not incur fees and  expenses in excess of $25,000 in the  aggregate  in order to
obtain  any  such  Required  Authorizations  described  in  clause  (ii)  of the
definition thereof without the prior written consent of Crane.

            (b) Without limiting the generality of the foregoing,  Crane, Merger
Sub and,  subject to Section  5.02 of this  Agreement,  the  Company  shall each
cooperate  with the  others  in  filing  in a timely  manner  any  applications,
requests,  reports,   registrations  or  other  documents,   including,  without
limitation,  all  reports  and  documents  required  to be filed by or under the
Exchange Act (including,  without limitation,  the Offer Documents, the Schedule
14D-9  and  the  Proxy  Statement),   with  any  Governmental  Authority  having
jurisdiction  with  respect  to  the  transactions  contemplated  hereby  and in
consulting with and seeking favorable action from any Governmental Authority.

            (c) Without limiting the generality of the foregoing, and subject to
Section 5.02 of this Agreement,  the Company shall,  and shall cause each of its
Subsidiaries to, take all 

                                       31
<PAGE>
reasonable  action  necessary to obtain all  approvals or consents of any person
needed in order that the  Contracts  continue in full force and effect under the
same terms and  conditions  currently in effect  following  consummation  of the
transactions contemplated by the Agreement;  provided, however, that the receipt
of any approval or consent under any Contracts  pursuant to this Section 5.04(c)
shall not be a condition  precedent  to the  obligations  of Parent or Purchaser
under this Agreement.

            (d) Without limiting the generality of the foregoing, and subject to
Section 5.02 of this Agreement, the Company and its Board of Directors shall (i)
take all reasonable action necessary to ensure that no state takeover statute or
similar  statute or  regulation  in effect on the date of this  Agreement  is or
becomes  applicable to the Offer, the Merger,  this Agreement,  the Stock Option
Agreement,   the  Shareholder  Agreements  or  any  of  the  other  transactions
contemplated  by this Agreement and (ii) if any such state  takeover  statute or
similar statute or regulation becomes applicable to the Offer, the Merger,  this
Agreement,  the Stock Option Agreement,  the Shareholder Agreements or any other
transaction contemplated by this Agreement, take all reasonable action necessary
to  ensure  that  the  Offer,  the  Merger,  the  Stock  Option  Agreement,  the
Shareholder Agreements and the other transactions contemplated by this Agreement
may be consummated as promptly as practicable on the terms  contemplated by this
Agreement  and otherwise to minimize the effect of such statute or regulation on
the Merger and the other transactions contemplated by this Agreement.

      SECTION  5.05.     Financial   Statements  of  the  Company.  As  soon  as
practicable but in any event within 30 days after the end of each calendar month
commencing  with July,  1998,  through the  consummation of the Offer or earlier
termination of this  Agreement in accordance  with Article VII, the Company will
deliver to Crane  unaudited  consolidated  balance sheets of the Company and its
Subsidiaries  as at the  end of  such  calendar  month  and as at the end of the
comparative  month of the preceding year,  together with unaudited  summaries of
consolidated  earnings  of the Company and its  Subsidiaries  for such  calendar
month and the  comparative  calendar  month of the  preceding  year.  As soon as
practicable but in any event within 30 days after the end of each fiscal quarter
of the Company,  commencing with June 30, 1998, and within 60 days after the end
of the fiscal year ended  December  31,  1998,  as the case may be,  through the
consummation of the Offer or earlier termination of this Agreement in accordance
with Article VII, the Company will deliver to Crane unaudited  consolidated  and
consolidating  balance sheets of the Company and its  Subsidiaries as at the end
of such fiscal  quarter and as at the end of the  comparative  fiscal quarter of
the  preceding  year,   together  with  the  related  unaudited   statements  of
consolidated  income and cash flows for the fiscal quarters then ended. All such
financial  statements  of the Company  shall  present  fairly,  in all  material
respects,  the financial  position,  results of operations and cash flows of the
Company and its  Subsidiaries,  as at or for the periods  indicated (and, in the
case of all such financial  statements which are interim  financial  statements,
shall  contain  all  adjustments  necessary  so to present  fairly) and shall be
prepared in accordance with generally accepted accounting principles (other than
to omit certain  footnotes which might be required  thereby and subject,  in the
case of interim financial statements, to normal year-end adjustments) consistent
with past practice,  except as otherwise indicated in such statements.  All such
financial  statements  of the  Company  shall be  certified,  on  behalf  of the
Company, by the President and Chief Financial Officer of the Company.

      SECTION 5.06.     Employee Matters. Crane agrees (a) that on and after the
consummation  of the  Offer  and  until  the date  that is 18  months  after the
Effective  Time,  Crane shall cause the Company and, on and after the  Effective
Time, the Surviving  Corporation,  to honor the severance  policy of the Company
and the employment agreements that are identified in Section 5.06 of the Company
Disclosure  Schedule,  (b) to give the  employees of the Company full credit for
purposes  of  eligibility  and  vesting  under  any  employee  benefit  plans or
arrangements maintained by Crane, the Surviving Corporation or any Subsidiary of
Crane for such employees' service with the Company or any of its Subsidiaries to
the same extent recognized by the Company  immediately prior to the consummation
of the  Offer,  (c) to waive  all  limitations  as to  pre-existing  conditions,
exclusions  or waiting  periods  with  respect  to  participation  and  coverage
requirements applicable to the Company employees under any welfare benefit plans
that such employees may be eligible to participate in after the  consummation of
the Offer and (d) to provide  employees of the Company  and,  from and after the
Effective Time, the Surviving Corporation,  with employee benefits comparable to
those  provided  by Crane (or any of its  Subsidiaries)  to  similarly  situated
employees of Crane (or any of its Subsidiaries).

      SECTION 5.07.     Rights  Agreement. The Board of Directors of the Company
shall take all further  action (in addition to that referred to in Section 3.27)
reasonably  requested  in  writing  by Crane  (including  redeeming  the  Rights
immediately  prior to the  Effective  Time or amending the Rights  Agreement) in
order to render the Rights  inapplicable to the Offer,  the Merger and the other
transactions contemplated by this Agreement.

                                       33
<PAGE>
      SECTION  5.08.     Continuance of Existing Indemnification Rights. (a) For
six years after the Effective Time, Crane shall, or shall cause the Company (or,
if after the Effective Time, the Surviving  Corporation) to,  indemnify,  defend
and hold  harmless  any person who is now,  or has been at any time prior to the
date  hereof,  or who  becomes  prior to the  Effective  Time,  a director or an
officer (an  "Indemnified  Person")  of the  Company or any of its  Subsidiaries
against all losses, claims, damages, liabilities,  costs and expenses (including
attorneys'  fees and  expenses),  judgments,  fines,  losses and amounts paid in
settlement in  connection  with any actual or threatened  action,  suit,  claim,
proceeding or  investigation  (each a "Claim") to the extent that any such Claim
is based on, or arises out of: (i) the fact that such  Indemnified  Person is or
was a director or an officer of the Company or any of its  Subsidiaries or is or
was  serving at the  request  of the  Company  or any of its  Subsidiaries  as a
director or an officer of another corporation, partnership, joint venture, trust
or  other  enterprise;  or  (ii)  this  Agreement  or any  of  the  transactions
contemplated  hereby, in each case to the extent that any such Claim pertains to
any matter or fact arising,  existing or occurring  prior to or at the Effective
Time,  regardless  of whether such Claim is asserted or claimed  prior to, at or
after the Effective  Time, to the full extent  permitted  under the PBCL and the
Company's  Articles of  Incorporation  or By-laws in effect at the date  hereof,
including provisions relating to advancement of expenses incurred in the defense
of any such Claim;  provided,  however,  that  neither  Crane nor the  Surviving
Corporation shall be required to indemnify any Indemnified  Person in connection
with any proceeding (or portion  thereof)  involving any Claim initiated by such
Indemnified Person unless the initiation of such proceeding (or portion thereof)
was  authorized by the Board of Directors of Crane or unless such  proceeding is
brought by an  Indemnified  Person to enforce  rights under this  Section  5.08.
Without  limiting the  generality  of the preceding  sentence,  in the event any
Indemnified  Person becomes involved in any Claim, after the consummation of the
Offer,  Crane shall, or shall cause the Surviving  Corporation to,  periodically
advance to such Indemnified  Person its legal and other expenses  (including the
cost of any  investigation  and preparation  incurred in connection  therewith),
subject  to the  providing  by such  Indemnified  Person  of an  undertaking  to
reimburse  all  amounts  so  advanced  in  the  case  of a  final  nonappealable
determination by a court of competent  jurisdiction that such Indemnified Person
is not entitled to be indemnified therefor.

            (b) Crane or the Surviving  Corporation shall maintain the Company's
existing  directors' and officers'  liability insurance policy ("D&O Insurance")
for a period of not less than six years  after  the  Effective  Time;  provided,
however,  that Crane may substitute  therefor policies of substantially  similar
coverage (including pursuant to Crane's own policy) and amounts containing terms
no less  advantageous  to such former  directors or officers;  provided  further
that, subject to the preceding proviso, if the existing D&O Insurance expires or
is canceled  during such period,  Crane or the Surviving  Corporation  shall use
their best efforts to obtain substantially  similar D&O Insurance;  and provided
further that neither  Crane nor the Surviving  Corporation  shall be required to
pay an annual  premium  for D&O  Insurance  in excess of 200% of the last annual
premium paid prior to the date hereof,  but in such case shall  purchase as much
coverage as possible for such amount.

            (c) In the event Crane or  Purchaser or any of their  successors  or
assigns (i)  consolidates  with or merges into any other person and shall not be
the  continuing  or surviving  corporation  or entity of such  consolidation  or
merger,  or (ii) transfers or conveys all or substantially all of its properties
and assets to any person,  then, in each such case,  to the extent  

                                       34
<PAGE>
necessary to  effectuate  the purposes of this Section  5.08,  proper  provision
shall be made so that the successors  and assigns of Crane and Purchaser  assume
the obligations set forth in this Section 5.08 and none of the actions described
in clauses (i) or (ii) shall be taken until such provision is made.

      SECTION 5.09.     Public Announcements. Crane and the Company will consult
with each other  before  issuing,  and  provide  each other the  opportunity  to
review,  comment  upon and  concur  with,  any  press  release  or other  public
statements  with respect to the  transactions  contemplated  by this  Agreement,
including  the Offer and the Merger,  and shall not issue any such press release
or make any such public statement prior to such  consultation,  except as may be
required by  applicable  law,  court process or by  obligations  pursuant to any
listing agreement with any national securities exchange.  The parties agree that
the  initial  press  releases  to be issued  with  respect  to the  transactions
contemplated by this Agreement shall be in the forms heretofore agreed to by the
parties.

      SECTION 5.10.     Shareholder Litigation. The Company shall give Crane the
opportunity  to  participate,  at no expense to the  Company,  in the defense or
settlement of any shareholder  litigation  against the Company and its directors
relating to the transactions  contemplated by this Agreement. No such settlement
shall be agreed to without Crane's consent; provided, however, that if a failure
to so consent is the sole cause of the occurrence of a Material  Adverse Effect,
then such Material Adverse Effect shall not be an Event for purposes of Annex II
nor shall Crane be  permitted  to  terminate  this  Agreement  solely due to the
occurrence of such Material Adverse Effect.

      SECTION  5.11.     Financial  Disclosure. The Company shall give Crane the
opportunity  to review and comment upon the Company's  Quarterly  Report of Form
10-Q for the quarter ending June 30, 1998.

            (a) Shareholder  Approval.  The Company  Shareholder  Approval shall

applicable  to the Merger under the HSR Act shall have been  terminated or shall
have expired.

            (c) No Injunctions or Restraints. No judgment, decree, statute, law,
ordinance,  rule,  regulation,   temporary  restraining  order,  preliminary  or
permanent injunction or other order enacted, entered,  promulgated,  enforced or
issued by any court of competent jurisdiction or other Governmental Authority or
other legal restraint or prohibition (collectively, "Restraints") preventing the
consummation of the Merger shall be in effect;  provided,  however, that each of


                                       35
<PAGE>
the parties shall have used all  reasonable  efforts to prevent the entry of any
such  Restraints and to appeal as promptly as possible any such  Restraints that
may be entered.

            (d)  Purchase of Company  Common  Stock.  The  Purchaser shall  have
accepted for payment and paid for shares of Company Common Stock pursuant to the
Offer  in  accordance  with the  terms  hereof;  provided,  however,  that  this
condition  shall be deemed to be  satisfied  with respect to the  obligation  of
Crane and the  Purchaser to effect the Merger if the  Purchaser  fails to accept
for payment or pay for shares of Company  Common Stock pursuant to the terms and
conditions of the Offer.

                                   ARTICLE VII

            (b)   by either Crane or the Company:

                  (i)   if the Offer is terminated or withdrawn  pursuant to its
terms  without any shares of Company  Common Stock being  purchased  thereunder;
provided,  however,  that  neither  Crane nor the  Company  may  terminate  this
Agreement  pursuant  to  this  Section  7.01(b)(i)  if  such  party  shall  have
materially breached this Agreement;

                  (ii)  if  the  Offer  has  not been  consummated  on or before
October 31, 1998; or

                  (iii) if any  Governmental  Authority  shall  have  issued  an
order,  decree,  ruling or  injunction  or taken any  other  action  permanently
enjoining, restraining or otherwise prohibiting acceptance for payment of shares
of Company Common Stock pursuant to the Offer or the  consummation of the Merger
and such order,  decree,  ruling,  injunction  or other action shall have become
final and nonappealable;

            (c)  by the Company if (i) Crane or the Purchaser  fails to commence
the Offer as provided in Section  1.01  hereof,  or (ii) Crane or the  Purchaser
shall not have accepted for payment and paid for shares of Company  Common Stock
pursuant to the Offer in violation  of the terms  hereof and thereof;  provided,
however,  that the Company may not  terminate  this  Agreement  pursuant to this
Section 7.01(c) if the Company shall have materially breached this Agreement;

            (d)  by the Company in accordance with Section  5.02(b) prior to the

provided that the Company has complied with all provisions thereof;

            (e)  by Crane  prior to  the purchase of  shares  of Company  Common

committee  thereof shall 

                                       36
<PAGE>
have  withdrawn  or  modified  in a manner  adverse  to Crane  its  approval  or
recommendation of the Offer (including by amendment of the Schedule 14D-9),  the
Merger or this Agreement,  or approved or recommended  any Superior  Proposal or
(ii) the Board of Directors of the Company or any  committee  thereof shall have
resolved to take any of the foregoing actions; or

            (f)  by Crane or the Purchaser  pursuant to Section  5.01(c) of this
Agreement.

      SECTION  7.02.     Effect  of Termination.  In the event of termination of
this Agreement by either the Company or Crane as provided in Section 7.01,  this
Agreement shall forthwith become void and have no effect,  without any liability
or  obligation  on the part of Crane,  Merger Sub or the Company,  except to the
extent that such  termination  results from the willful and material breach by a
party of any of its  representations,  warranties,  covenants or agreements  set
forth in this  Agreement;  provided  that the  provisions  of this Section 7.02,
Section  7.03 and Article VIII shall remain in full force and effect and survive
any termination of this Agreement.

      SECTION  7.03.     Fees  and  Expenses.  (a)  Except  as set forth in this
Section 7.03, all fees and expenses  incurred in connection  with this Agreement
and the  transactions  contemplated  hereby shall be paid by the party incurring

            (b) The Company shall  reimburse  Crane for  out-of-pocket  expenses
incurred by Crane relating to the  transactions  contemplated  by this Agreement
prior to  termination  (including,  but not  limited  to,  fees and  expenses of

have been  terminated  pursuant  to  Sections  7.01(d) or (e),  (ii) the Company
enters into an Acquisition Agreement with a party other than Crane or any of its
Affiliates  within  one  year of the  date of such  termination  and  (iii)  the
transaction  contemplated by such Acquisition Agreement is consummated within 18
months  of the date of such  termination.  Such  reimbursement  shall be paid in
same-day funds within one business day after the consummation of the transaction
contemplated by any such Acquisition Agreement.

      SECTION 7.04.     Amendment.  This Agreement may be amended by the parties
at any time before or after the Company Shareholder Approval; provided, however,

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

      SECTION  7.05.     Extension;  Waiver.  At any time prior to the Effective

the part of a party to any such  extension  or waiver shall be valid only if set
forth in an instrument in writing signed on 

                                       37
<PAGE>
behalf of such party.  The failure of any party to this  Agreement to assert any
of its rights under this Agreement or otherwise shall not constitute a waiver of
such rights.

      SECTION  7.06.     Procedure  for  Termination,  Amendment,  Extension  or
Waiver.  A termination of this Agreement  pursuant to Section 7.01, an amendment
of this Agreement pursuant to Section 7.04 or an extension or waiver pursuant to

Directors  or, with respect to any  amendment to this  Agreement,  to the extent
permitted  by  applicable  law,  a duly  authorized  committee  of its  Board of
Directors.

the  representations  and  warranties  in this  Agreement  or in any  instrument

its terms contemplates performance after the Effective Time.

as the "Shareholder");

                                   WITNESSETH:

      WHEREAS,  the Shareholder,  as of the date hereof,  is the owner of or has
the sole right to vote the number of shares of common stock,  par value $.01 per
share  ("Common  Stock"),   of  Liberty   Technologies,   Inc.,  a  Pennsylvania

signature  page  hereof,  together  with the Rights  associated  therewith  (the
"Shares"); and

      WHEREAS,  in reliance upon the  execution and delivery of this  Agreement,
Crane  will  enter into an  Agreement  and Plan of Merger,  dated as of the date
hereof  (the  "Merger  Agreement"),  with,  among  others,  the  Company,  which
provides,  among other things, that upon the terms and subject to the conditions
thereof,  the Offer will be made and the  Company  will become  wholly  owned by
Crane at the Effective Time of the Merger; and

      WHEREAS,  to induce Crane to enter into the Merger  Agreement and to incur
the  obligations  set forth  therein,  the  Shareholder  is  entering  into this
Agreement  pursuant  to which  the  Shareholder  agrees  to vote in favor of the
transactions  contemplated by the Merger  Agreement and certain other matters as
set forth herein, and to make certain agreements with respect to the Shares upon
the terms and conditions set forth herein;

      NOW  THEREFORE,  in  consideration  of the  foregoing  and  of the  mutual
covenants  and  agreements  set forth  herein  and for other  good and  valuable
consideration,  the receipt and  adequacy of which is hereby  acknowledged,  and
intending to be legally bound, the parties hereto agree as follows:

      Section  1.  TENDER OF SHARES.  The  Shareholder  covenants  and agrees to
tender,  or cause to be  tendered,  and to not  (without  the  consent of Crane)
withdraw  the Shares owned by such  Shareholder  pursuant to the Offer until the
earlier of (i) the date on which the Offer is  terminated  or  withdrawn or (ii)
the date on which the Merger Agreement is terminated.

Agreement is  terminated or (iii) the purchase of all of the Shares owned by the
Shareholder  pursuant  to the Offer  (the  earliest  thereof  being  hereinafter
referred to as the "Expiration  Date"),  the  Shareholder  shall vote all Shares
owned by the Shareholder at any meeting of the Company's  shareholders  (whether
annual or special and whether or not an adjourned  meeting),  or, if applicable,
take  action by written  consent  (x) for  adoption  and  approval of the Merger
Agreement and in favor of the Merger and otherwise in favor of the  transactions
contemplated by the Merger Agreement as such Merger Agreement may be modified or

<PAGE>

or agreement  which would or could impede or interfere  with, or have the effect
of  discouraging,   the  transactions  contemplated  by  the  Merger  Agreement,
including,   without  limitation,   any  Acquisition  Proposal  other  than  the
transactions  contemplated by the Merger Agreement.  Any such vote shall be cast
or consent shall be given in accordance with such procedures relating thereto as
shall ensure that it is duly counted for purposes of  determining  that a quorum
is present and for purposes of recording the results of such vote or consent.

      (b) At the  request  of Crane,  the  Shareholder,  in  furtherance  of the
transactions  contemplated  hereby and by the Merger Agreement,  and in order to
secure the  performance by the  Shareholder of such  Shareholder's  duties under
this  Agreement,  shall promptly  execute,  in accordance with the provisions of
Section 1759(c) of the  Pennsylvania  Business  Corporation  Law, and deliver to
Crane, an irrevocable  proxy,  substantially in the form of Annex A hereto,  and
irrevocably  appoint Crane or its  designees,  with full power of  substitution,
such  Shareholder's  attorney  and  proxy to vote,  or, if  applicable,  to give
consent with respect to, all of the Shares owned by the  Shareholder  in respect
of any of the matters set forth in, and in accordance  with the  provisions  of,
clauses (i) and (ii) above of Section 1(a). The  Shareholder  acknowledges  that
the proxy  executed and delivered by such  Shareholder  shall be coupled with an
interest, shall constitute, among other things, an inducement for Crane to enter
into the Merger  Agreement,  shall be irrevocable and shall not be terminated by
operation  of  law  upon  the  occurrence  of  any  event,  including,   without
limitation,  the death or incapacity  of the  Shareholder.  Notwithstanding  any
provision  contained  in  such  proxy,  such  proxy  shall  terminate  upon  the
Expiration Date.

      (c) The  Shareholder  agrees,  and shall  take all  actions  necessary  to
ensure,  that the certificate(s)  evidencing the Shares shall have the following
legend placed thereon (in addition to any legend required under applicable state
or federal securities law):

      "THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  ARE  SUBJECT TO AN OPTION
      PURSUANT TO A  SHAREHOLDER  AGREEMENT  DATED AUGUST 11, 1998,  BETWEEN THE
      SHAREHOLDER  WHOSE NAME  APPEARS ON THIS  CERTIFICATE  AND CRANE CO.  (THE

      Section 3. COVENANTS OF THE  SHAREHOLDER.  The  Shareholder  covenants and
agrees for the benefit of Crane that such Shareholder, in his or her capacity as
a Shareholder, will:

            (a) until the date that is six  months  after the  Expiration  Date,
      except for the  tendering  of the Shares  pursuant to the Offer and except

      owned by such Shareholder or any interest  therein,  unless and until such
      transferee  executes  and  delivers  to Crane a joinder to this  Agreement
      pursuant to which such  transferee  shall agree that,  for all purposes of
      this  Agreement,   (i)  such   transferee   shall  be  deemed  to  be  the
      "Shareholder"  hereunder  and (ii) all shares of the  Common  Stock of the
      Company transferred to such transferee pursuant to this Section 3(a) shall
      be deemed to be "Shares" hereunder;

            (c) until the  Expiration  Date,  not, and cause such  Shareholder's
      agents  and  representatives  not  to,  initiate,  solicit  or  encourage,
      directly or indirectly,  any inquiries or the making or  implementation of
      any  Acquisition  Proposal or engage in any  negotiations  concerning,  or
      provide any  confidential  information or data to, or have any discussions
      with,  any  person  relating  to  a  Acquisition  Proposal,  or  otherwise
      facilitate  any  effort or  attempt  to make or  implement  a  Acquisition
      Proposal.  The  Shareholder  shall  immediately  cease  and  cause  to  be
      terminated any existing activities,  including discussions or negotiations
      with  any  parties,  conducted  heretofore  with  respect  to  any  of the
      foregoing and will take the necessary  steps to inform such  Shareholder's
      agents and  representatives of the obligations  undertaken in this Section
      3(c). The Shareholder shall notify Crane immediately if any such inquiries
      or proposals are received by, any such  information is requested  from, or
      any such  negotiations  or  discussions  are  sought  to be  initiated  or
      continued with, such Shareholder.

      Section 4. GRANT OF OPTION.  (a) The Shareholder hereby grants to Crane an
irrevocable  option (the  "Option")  to  purchase  all or any part of the Shares
owned by such  Shareholder  (the "Option Shares") at a price of $3.50 per Option
Share.

            (b) The Option may be  exercised by Crane,  in whole or in part,  at
any  time  or  from  time to time  if the  Company  enters  into an  Acquisition
Agreement  with a party  other  than Crane or any of its  Affiliates  within six
months after the Expiration Date;

            (c) In the event Crane  wishes to exercise  the Option,  Crane shall
send a written notice (an "Exercise  Notice") to the Shareholder  specifying the
total number of Option Shares Crane wishes to purchase, the denominations of the
certificate or certificates  evidencing such Option Shares which Crane wishes to
receive,  a date (a "Closing  Date"),  which shall be a business day which is at
least  three  business  days after  delivery of such  notice,  and place for the
closing of such purchase (a "Closing").  Upon receipt of an Exercise Notice, the
Shareholder  shall be obligated to deliver to Crane the number of Option  Shares
specified therein, in accordance with the terms of this Agreement,  on the later
of (i) the Closing Date and (ii) the first  business day on which there shall be
no preliminary or permanent  injunction or other order by and court of competent
jurisdiction  preventing  or  prohibiting  such  exercise  of the  Option or the
delivery of the Option Shares in respect of such exercise.  At each Closing, the
Shareholder  will deliver to Crane a certificate or certificates  evidencing the
number of Option Shares specified in Crane's Exercise Notice,  registered in the
name of Crane or its  nominee,  and Crane will  deliver to the  Shareholder  the
aggregate  purchase price for such Option Shares.  All payments made by Crane to
the  Shareholder  pursuant to this Section 4 shall be made, at the option of the
Shareholder,  by wire transfer of immediately available funds, or by delivery to
the  Shareholder  of a  certified  or bank check or checks  payable to or on the
order of the Shareholder.

do,  or  cause  to be  done,  all  things  necessary  or  advisable  in order to

Shareholder  represents and warrants to Crane that: (a) the execution,  delivery
and  performance  by the  Shareholder  of this Agreement will not conflict with,
require a consent, waiver or approval under, or result in a breach of or default
under, any of the terms of any contract, commitment or other obligation (written
or oral) to which the  Shareholder is bound,  other than  consents,  waivers and
approvals  the  absence of which  would not  reasonably  be  expected to have an
adverse effect on the  Shareholder's  ability to perform his or her  obligations
hereunder and except for such  conflicts,  breaches or defaults  which would not
reasonably be expected to have an adverse effect on the Shareholder's ability to
perform  his or her  obligations  hereunder;  (b) this  Agreement  has been duly
executed and delivered by the  Shareholder  and  constitutes a legal,  valid and
binding  obligation of the Shareholder,  enforceable  against the Shareholder in

moratorium,  reorganization,  fraudulent conveyance and similar laws relating to
or  affecting  creditors'  rights  generally  and court  decisions  with respect
thereto,  and  subject  to the  application  of  equitable  principles  and  the
discretion of the court (regardless of whether the  enforceability is considered
in a proceeding in equity or at law);  (c) the  Shareholder is the sole owner of
or has the sole right to vote the Shares and the Shares  represent all shares of
Common Stock which the Shareholder is the sole owner of or has the sole right to
vote at the date hereof, and the Shareholder does not have any right to acquire,
nor is he or she the  "beneficial  owner" (as such term is defined in Rule 13d-3
under the  Securities  Exchange Act of 1934, as amended) of, any other shares of
any class of capital stock of the Company or any securities  convertible into or
exchangeable  or exercisable for any shares of any class of capital stock of the
Company  (other than shares  subject to options or other  rights  granted by the
Company); (d) the Shareholder has full right, power and authority to execute and
deliver this Agreement and to perform his or her obligations hereunder;  and (e)
the Shareholder  owns the Shares free and clear of all liens,  claims,  pledges,
charges, proxies, restrictions,  encumbrances, proxies, voting trusts and voting
agreements of any nature  whatsoever,  other than restrictions upon resale which
may be imposed by federal or state securities laws and other than as provided by
this Agreement.  The  representations  and warranties  contained herein shall be
made  as of the  date  hereof  and,  with  respect  to the  representations  and
warranties  set forth in clauses  (c), (d) and (e) of this Section 6, as of each
day from the date hereof  through and including the earlier to occur of the date
that is six months after the Expiration Date or the date of the  consummation of

<PAGE>

Common Stock or other  securities  entitling the holder  thereof to vote or give
consent with respect to the matters set forth in Section 2, then such additional
shares of Common Stock and other securities shall become Option Shares hereunder

stock or other  instruments  or documents  held by the  Shareholder  immediately
following  the  effectiveness  of the  events  described  in  clause  (a) or the

agreements  contained in this Agreement are an integral part of the transactions
contemplated by the Merger Agreement, and that, without these agreements,  Crane
would not enter into the Merger  Agreement,  and acknowledges that damages would
be an inadequate  remedy for any breach by him or her of the  provisions of this
Agreement.   Accordingly,   the  Shareholder  and  Crane  each  agree  that  the
obligations  of the parties  hereunder  shall be  specifically  enforceable  and
neither  party shall take any action to impede the other from seeking to enforce
such right of specific performance.

                                    ARTICLE I

                                THE STOCK OPTION

      Section 1.1 GRANT OF STOCK OPTION.  The Company  hereby grants to Crane an
irrevocable  option (the "Stock  Option") to purchase up to 997,633 newly issued
shares (the "Option Shares") of common stock, par value $.01 per share, together
with the Rights associated therewith, of the Company ("Company Common Stock") in
the manner set forth below at a price (the "Purchase Price") of $2.75 per Option
Share.  Capitalized  terms used  herein but not  defined  herein  shall have the
meanings set forth in the Merger Agreement.

      Section 1.2 EXERCISE OF STOCK OPTION.  (a) Subject to the  satisfaction of
the  conditions  set  forth in  Section  1.3  hereof,  the Stock  Option  may be
exercised by Crane,  in whole or in part, at any time or from time to time after
the  occurrence  of an  Exercise  Event  (as  defined  below)  and  prior to the
Termination Date (as defined below).

            (b) An "Exercise  Event" shall occur for purposes of this  Agreement
upon the termination of the Merger Agreement  pursuant to Section 7.01(d) or (e)
thereof.


<PAGE>

            (c)  The  "Termination  Date"  shall  occur  for  purposes  of  this
Agreement upon the first to occur of any of the following:

                       (i) the consummation of the Offer;

                   (ii) the date on which the  Merger  Agreement  is  terminated
      pursuant to Section  7.01  thereof,  if an  Exercise  Event shall not have
      occurred; or

                  (iii) the date  which is 365 days  after the date on which the
      Merger  Agreement is terminated  pursuant to Section 7.01  thereof,  if an
      Exercise Event shall have occurred;

provided that, with respect to clause (iii) above, if the Stock Option cannot be
exercised as of such date by reason of any  applicable  judgment,  decree,  law,
regulation or order,  then the Termination  Date shall be extended until fifteen
days after such impediment has been removed.

            (d) In the event Crane  wishes to exercise the Stock  Option,  Crane
shall send a written notice (an "Exercise Notice") to the Company specifying the
total number of Option Shares,  if any, Crane wishes to purchase,  the number of
Option  Shares,  if any,  with  respect to which Crane  wishes to  exercise  its
Cash-Out  Right  (as  defined  herein)  pursuant  to  Section  1.4  hereof,  the
denominations  of the certificate or certificates  evidencing such Option Shares
which Crane  wishes to  receive,  a date (a  "Closing  Date"),  which shall be a
business  day which is at least  three  business  days  after  delivery  of such
notice, and place for the closing of such purchase (a "Closing").

            (e)  Upon  receipt  of an  Exercise  Notice,  the  Company  shall be
obligated to deliver to Crane the number of Option Shares specified therein,  in
accordance  with the terms of this  Agreement,  on the later of (i) the  Closing
Date and (ii) the first  business day on which there shall be no  preliminary or
permanent  injunction  or other  order by any  court of  competent  jurisdiction
preventing or  prohibiting  such exercise of the Stock Option or the delivery of
the Option Shares in respect of such exercise.

      Section 1.3 CLOSINGS. At each Closing, the Company will deliver to Crane a
certificate or certificates  evidencing the number of Option Shares specified in
Crane's  Exercise  Notice,  registered in the name of Crane or its nominee,  and
Crane will deliver to the Company the aggregate  Purchase  Price for such Option
Shares.  All payments made by Crane to the Company  pursuant to this Section 1.3
shall be made, at the option of Crane, by wire transfer of immediately available
funds,  or by delivery  to the  Company of a  certified  or bank check or checks
payable to or on the order of the Company.

      Section 1.4 CASH-OUT RIGHT.  If, at any time during the period  commencing
on the occurrence of an Exercise Event and terminating on the Termination  Date,
Crane sends to the Company an Exercise  Notice  indicating  Crane's  election to
exercise its rights (the  "Cash-Out  Right")  pursuant to this Section 1.4, then
the  Company  shall pay to Crane,  on the  Closing  Date,  in  exchange  for the
cancellation of the Stock Option with respect to such number of Option Shares as
Crane specifies in the Exercise  Notice,  an amount in cash equal to such number
of Option Shares  multiplied by the difference  between (i) the average  closing
price for the 10 trading days  commencing  on the 12th  trading day  immediately
preceding the date of the Exercise

                                      -2-
<PAGE>

Notice per share of Company  Common  Stock (the  "Average  Price")  and (ii) the
Purchase Price. If Crane has sent an Exercise Notice to the Company prior to the
Termination  Date,  Crane  shall be  entitled  to all of its  rights  under this
Section  1.4  to  the  extent   exercised   pursuant  to  the  Exercise   Notice
notwithstanding  the failure of the  Company to perform  all of its  obligations
under this Section 1.4 prior to the Termination Date.

      Section 1.5 ADJUSTMENTS UPON SHARE ISSUANCES,  CHANGES IN  CAPITALIZATION,
ETC. (a) In the event of any change in Company  Common Stock or in the number of
outstanding  shares of  Company  Common  Stock by  reason  of a stock  dividend,
split-up,   recapitalization,   combination,   exchange  of  shares  or  similar
transaction  or any other change in the  corporate  or capital  structure of the
Company  (including,  without  limitation,  the  declaration  or  payment  of an
extraordinary  dividend of cash,  securities  or other  property),  the type and
number of shares or  securities to be issued by the Company upon exercise of the
Stock Option shall be adjusted appropriately, and proper provision shall be made
in the agreements  governing such transaction,  so that Crane shall receive upon
exercise of the Stock Option the number and class of shares or other  securities
or property that Crane would have received in respect of Company Common Stock if
the Stock  Option had been  exercised  immediately  prior to such event,  or the
record date therefor,  as applicable,  and such Company Common Stock had elected
to the fullest  extent it would have been  permitted  to elect,  to receive such
securities, cash or other property.

            (b) No  adjustment  made in  accordance  with this Section 1.5 shall
constitute  or be  deemed  a  waiver  of any  breach  of  any  of the  Company's
representations,  warranties,  covenants, agreements or obligations contained in
the Merger Agreement.

            (c) The provisions of this Agreement, including, without limitation,
Sections 1.1, 1.2, 1.3, 1.4 and 3.2, shall apply with appropriate adjustments to
any securities for which the Stock Option becomes  exercisable  pursuant to this
Section 1.5.

      Section 1.6 COVENANTS OF CRANE.  Crane agrees not to transfer or otherwise
dispose of the Option or the Option Shares, or any interest  therein,  except in
compliance  with the Securities Act of 1933, as amended (the  "Securities  Act")
and any applicable  state securities laws. Crane further agrees to the placement
of the following legend on the certificate(s) representing the Option Shares (in
addition to any legend required under applicable state securities laws):

            "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER EITHER (i) THE  SECURITIES ACT OF 1933, AS AMENDED (THE "ACT")
            OR (ii) ANY  APPLICABLE  STATE LAW  GOVERNING  THE OFFER AND SALE OF
            SECURITIES,  NO TRANSFER OR OTHER DISPOSITION OF THESE SHARES, OR OF
            ANY INTEREST  THEREIN,  MAY BE MADE EXCEPT  PURSUANT TO AN EFFECTIVE
            REGISTRATION  STATEMENT  UNDER THE ACT AND SUCH OTHER  STATE LAWS OR
            PURSUANT TO EXEMPTIONS FROM  REGISTRATION  UNDER THE ACT, SUCH OTHER

                            COVENANTS OF THE COMPANY

      Section 3.1 LISTING;  OTHER ACTION. (a) The Company shall, at its expense,
use its best  efforts to cause the Option  Shares to be approved  for trading on
the  Nasdaq  National  Market  ("Nasdaq"),  subject  to notice of  issuance,  as
promptly as practicable  following the date of this Agreement,  and will provide
prompt notice to Nasdaq of the issuance of each Option Share.

            (b) The Company  shall use its best efforts to take,  or cause to be
taken,  all  appropriate  action,  and to do,  or cause to be done,  all  things
necessary,  proper  or  advisable  under  applicable  laws  and  regulations  to
consummate  and  make  effective  the   transactions   contemplated   hereunder,
including,  without  limitation,  obtaining  all  licenses,  permits,  consents,
approvals,   authorizations,   qualifications   and   orders   of   Governmental
Authorities.

      Section  3.2  REGISTRATION.  (a) As used in this  Agreement,  "Registrable
Securities"  means each of the Option Shares  issued to Crane  hereunder and any
other securities  issued in exchange for, or issued as dividends or otherwise on
or in respect of, any of such Option Shares.

            (b) At any time or from time to time  following  the first  Closing,
Crane may make a written  request to the Company for  registration  under and in
accordance with the provisions of the Securities Act with respect to all or part
of the Registrable Securities (a "Demand  Registration").  A Demand Registration
may be, at the option of Crane, a shelf registration or a registration involving
an  underwritten  offering.  As soon as  reasonably  practicable  after  Crane's
request  for  a  Demand  Registration,  the  Company  shall  file  one  or  more
registration  statements  on any  appropriate  form with  respect  to all of the
Registrable Securities requested to be so registered;  provided that the Company
will not be required to file any such  registration  statement during any period
of time (not to exceed 30 days after such  request)  when (A) the  Company is in
possession of material non-public information which it reasonably believes, upon
the advice of its outside counsel,  would have to be disclosed if a registration
statement  were filed at that time,  and that any such  disclosure  at that time
would be materially  detrimental to the Company,  or (B) the Company is required
under the Securities Act to include audited financial  statements for any period
in such registration statement that are not yet available for inclusion therein.
The Company shall use its best efforts to have the Demand Registration  declared
effective as soon as  reasonably  practicable  after such filing and to keep the
Demand Registration  continuously effective;  provided that the effectiveness of
any Demand  Registration  may be terminated  if and when all of the  Registrable
Securities  covered  thereby  shall have been sold.  If any Demand  Registration
involves  an  underwritten  offering,  (i) the  Company  shall have the right to
select the managing underwriter,  which shall be reasonably acceptable to Crane,
and (ii) the Company  shall enter into an  underwriting  agreement  in customary
form.  The Company shall not include in any Demand  Registration  any securities
other than the  Registrable  Securities  requested to be  registered  therein by
Crane.

            (c) Up to two registrations effected under this Section 3.2 shall be
effected at the Company's expense except for underwriting  commissions allocable
to the  Registrable

and fees and  disbursements of counsel and accountants)  arising out of or based
upon any statements  contained in, or omissions or alleged  omissions from, each
registration  statement (and related  prospectus) filed pursuant to this Section
3.2; provided, however, that the Company shall not be liable in any such case to
Crane or any affiliate or controlling person of Crane or any of their respective
officers, directors, agents or representatives to the extent that any such loss,
claim, damage, liability (or action or proceeding in respect thereof) or expense
arises  out of or is based  upon an untrue  statement  or  omission  or  alleged
omission made in such registration statement or prospectus in reliance upon, and
in conformity with, written  information  furnished to the Company  specifically
for use in the preparation thereof by Crane, such affiliate, controlling person,
officer, director, agent or representative, as the case may be.


                                   ARTICLE IV
