To: All Holders of Shares of Common Stock of Liberty Technologies, Inc.: 

                                 INTRODUCTION 

   LTI Merger, Inc. (the "Purchaser"), a Pennsylvania corporation and a 
wholly owned subsidiary of Crane Co., a Delaware corporation ("Crane"), 
hereby offers to purchase all outstanding shares of common stock, par value 
$.01 per share (the "Shares" or "Company Common Stock"), of Liberty 
Technologies, Inc., a Pennsylvania corporation (the "Company"), and the 
associated Preferred Stock Purchase Rights (the "Rights") issued pursuant to 
the Amended and Restated 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           
<PAGE>
   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. 

6. PRICE RANGE OF THE SHARES; DIVIDENDS

   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. 

                               12           
<PAGE>
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

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.

   For purposes of the Merger Agreement, "Material Adverse Effect" means a 
material adverse effect on the business, assets (including intangible 
assets), condition (financial or otherwise), or results of operations of the

purposes of the Merger Agreement, (a) a decline in the market price of the

other third-party franchise, license or permit, other than any such consents, 
authorizations, approvals, permits, qualifications, waivers, orders,

Agreement contains customary representations and warranties by Crane and the 
Purchaser, including, among other things, (i) with respect to the

    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 

                               18           
<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 obligations, except, in any case, issuance of shares of the 
    Company Common Stock (i) pursuant to the exercise of outstanding options, 
    warrants or other rights or (ii) pursuant to the Stock Option Agreement; 

     (xvi) not make any change to its accounting methods, principles or 
    practices, except as may be required by generally accepted accounting 
    principles; 

     (xvii) not expend any money pursuant to, or incur expenses related to 
    performance under, the Development Contract with Norwegian Oil Companies, 
    Saga Petroleum ASA, Phillips Petroleum Co., Statoil and Norsk Hydro 
    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

    directly or indirectly, in, any of the consequences referred to in clauses

    there is a substantial likelihood of resulting in any of the consequences 
    referred to in clauses (i) through (v) of paragraph (a) above; or 

                               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

    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

    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

    institutions, or (iv) with 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

   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.

                    SECTIONS 1930(A) AND 1571 THROUGH 1580

corporate action, or to otherwise obtain fair value for his shares, where 
this part expressly provides that a shareholder shall have the rights and 
remedies provided in this subchapter. See: 

   Section 1906(c) (relating to dissenters rights upon special treatment). 

   Section 1930 (relating to dissenters rights). 

   Section 1931(d) (relating to dissenters rights in share exchanges).

transfer of a security is held invalid). 

   Section 2325(b) (relating to minimum vote requirement). 

   Section 2704(c) (relating to dissenters rights upon election).

   (b) Exceptions. (1) Except as otherwise provided in paragraph (2) , the 
holders of the shares of any class or series of shares that, at the record 
date fixed to determine the shareholders entitled to notice of and to vote at 
the meeting at which a plan specified in any of sections 1930, 1931(d), 
1932(c) or 1952(d) is to be voted on, are either: 

   (i) listed on a national securities exchange; or 

   (ii) held of record by more than 2,000 shareholders; shall not have the 
right to obtain payment of the fair value of any such shares under this 
subchapter. 

   (2) Paragraph (1) shall not apply to and dissenters rights shall be

case of: 

   (i) Shares converted by a plan if the shares are not converted solely into

<PAGE>
   (ii) Shares of any preferred or special class unless the articles, the

shareholders of the class. 

   (iii) Shares entitled to dissenters rights under section 1906(c) (relating

other corporation and with or without the intervention of another corporation 
or other person, shall not be entitled to the rights and remedies of 
dissenting shareholders provided in this subchapter regardless of the fact,

acquisition sufficient to elect a majority or more of the directors of the 
corporation. 

   (c) Grant of optional dissenters rights. The bylaws or a resolution of 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.

relaxed by any provision of the articles.

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

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.

Ladies and Gentlemen: 

   The undersigned hereby tenders to LTI Merger, Inc., a Pennsylvania 
corporation ("Purchaser") and a wholly owned subsidiary of Crane Co., a 
Delaware corporation, the above described shares of common stock, par value 
$.01 per share (the "Shares") of Liberty Technologies, Inc., a Pennsylvania 
corporation (the "Company"), including the associated Preferred Stock 
Purchase Rights (the "Rights") issued pursuant to the Amended and Restated 
Rights Agreement, dated as of October 6, 1997, between the Company and 
StockTrans, Inc., as Rights Agent (the "Rights Agreement"), at a price of 
$3.50 per Share, net to the seller in cash, without interest thereon (the 
"Offer Price"), upon the terms and subject to the conditions set forth in the 
Offer to Purchase, dated August 14, 1998 (the "Offer to Purchase"), and in 
this Letter of Transmittal (which, as amended from time to time, together 
constitute the "Offer"). Unless the Rights are redeemed by the Company, a 
tender of the Shares will also constitute a tender of the associated Rights. 
Unless the context requires otherwise, all references herein to the Shares 
shall include the associated Rights, and all references to the Rights shall 
include all benefits that may inure to the holders of the Rights pursuant to 
the Rights Agreement. 

   Subject to, and effective upon, acceptance for payment of the Shares 
tendered herewith, in accordance with the terms of the Offer (including, if 
the Offer is extended or amended, the terms and conditions of any such 
extension or amendment), the undersigned hereby sells, assigns and transfers 
to, or upon the order of, Purchaser all right, title and interest in and to 
all the Shares that are being tendered hereby (and any and all non-cash 
dividends, distributions, rights, other Shares or other securities issued or 
issuable in respect thereof or declared, paid or distributed in respect of 
such Shares on or after August 14, 1998 (collectively, "Distributions")), 
purchased pursuant to the Offer and irrevocably appoints the Depositary the 
true and lawful agent and attorney-in-fact of the undersigned with respect to 
such Shares and all Distributions, with full power of substitution (such 
power of attorney being deemed to be an irrevocable power coupled with an 
interest), to (i) deliver certificates for such Shares (individually, a 
"Share Certificate") and all Distributions, or transfer ownership of such 
Shares and all Distributions on the account books maintained by the 
Book-Entry Transfer Facility, together, in either case, with all accompanying 
evidence of transfer and authenticity to, or upon the order of, Purchaser, 
(ii) present such Shares and all Distributions for transfer on the books of 
the Company, and (iii) receive all benefits and otherwise exercise all rights 
of beneficial ownership of such Shares and all Distributions, all in 
accordance with the terms of the Offer. 

   The undersigned hereby represents and warrants that the undersigned has 
full power and authority to tender, sell, assign and transfer the Shares 
tendered hereby and all Distributions, that the undersigned own(s) the Shares 
tendered hereby and that, when such Shares are accepted for payment by 
Purchaser, Purchaser will acquire good, marketable and unencumbered title 
thereto and to all Distributions, free and clear of all liens, restrictions, 
charges and encumbrances, and that none of such Shares and Distributions will 
be subject to any adverse claim. The undersigned, upon request, shall execute 
and deliver all additional documents deemed by the Depositary or Purchaser to 
be necessary or desirable to complete the sale, assignment and transfer of 
the Shares tendered hereby and all Distributions. In addition, the 
undersigned shall remit and transfer promptly to the Depositary for the 
account of Purchaser all Distributions in respect of the Shares tendered 
hereby, accompanied by appropriate documentation of transfer, and, pending 
such remittance and transfer or appropriate assurance thereof, Purchaser 
shall be entitled to all rights and privileges as owner of each such 
Distribution and may withhold the entire purchase price of the Shares 
tendered hereby or deduct from such purchase price, the amount or value of 
such Distribution as determined by Purchaser in its sole discretion. The 
undersigned further represents and warrants that the undersigned has read and 
agrees to all terms of the Offer. 

   No authority herein conferred or agreed to be conferred shall be affected 
by, and all such authority shall survive, the death or incapacity of the 
undersigned. All obligations of the undersigned hereunder shall be binding 
upon the heirs, executors, personal and legal representatives, 
administrators, trustees in bankruptcy, successors and assigns of the 
undersigned. Except as stated in the Offer to Purchase, this tender is 
irrevocable. 

   The undersigned understands that tenders of Shares pursuant to any one of 
the procedures described in "Procedures for Accepting the Offer and Tendering 
Shares" of the Offer to Purchase and in the Instructions hereto will 
constitute the undersigned's acceptance of the terms and conditions of the 
Offer. Purchaser's acceptance for payment of Shares tendered pursuant to the 
Offer will constitute a binding agreement between the undersigned and 
Purchaser upon the terms and subject to the conditions of the Offer. The 
undersigned recognizes that under certain circumstances set forth in the 
Offer to Purchase, Purchaser may not be required to accept for payment any of 
the Shares tendered hereby.

                                 INSTRUCTIONS 
            FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER 

1. GUARANTEE OF SIGNATURES. 

   Except as otherwise provided below, all signatures on this Letter of 
Transmittal must be guaranteed by a firm which is a bank, broker, dealer, 
credit union, savings association, or other entity that is a member in good 
standing of the Securities Transfer Agents Medallion Program (each, an 
"Eligible Institution"). No signature guarantee is required on this Letter of 
Transmittal (i) if this Letter of Transmittal is signed by the registered 
holder(s) (which term, for purposes of this document, shall include any 
participant in the Book-Entry Transfer Facility whose name appears on a 
security position listing as the owner of Shares) of Shares tendered 
herewith, unless such holder(s) has completed either the box entitled 
"Special Delivery Instructions" or the box entitled "Special Payment 
Instructions" included herein, or (ii) if such Shares are tendered for the 
account of an Eligible Institution. See Instruction 5. 

2. DELIVERY OF LETTER OF TRANSMITTAL AND SHARE CERTIFICATES; GUARANTEED 
   DELIVERY PROCEDURES. 

   This Letter of Transmittal is to be used either if certificates evidencing 
Shares ("Certificates") are to be forwarded herewith or if Shares are to be 
delivered by book-entry transfer pursuant to the procedure set forth in 
"Procedures for Accepting the Offer and Tendering Shares" of the Offer to 
Purchase, unless an Agent's Message is transmitted to the Book-Entry Transfer 
Facility. Certificates evidencing all tendered Shares, or confirmation of a 
book-entry transfer of such Shares, if such procedure is available, into the 
Depositary's account at the Book-Entry Transfer Facility pursuant to the 
procedures set forth in "Procedures for Accepting the Offer and Tendering 
Shares" of the Offer to Purchase, 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 this Letter of 
Transmittal, must be received by the Depositary at one of its addresses set 
forth herein prior to the Expiration Date (as defined in "Terms of the Offer" 
of the Offer to Purchase). If Certificates are forwarded to the Depositary in 
multiple deliveries, a properly completed and duly executed Letter of 
Transmittal must accompany each such delivery. Shareholders whose 
Certificates are not immediately available, who cannot deliver their 
Certificates and all other required documents to the Depositary prior to the 
Expiration Date or who cannot complete the procedure for delivery by 
book-entry transfer on a timely basis may tender their Shares pursuant to the 
guaranteed delivery procedure described in "Procedures for Accepting the 
Offer and Tendering Shares" of the Offer to Purchase. Pursuant to such 
procedure: (i) such tender must be made by or through an Eligible 
Institution; (ii) a properly completed and duly executed Notice of Guaranteed 
Delivery, substantially in the form provided by Purchaser herewith, must be 
received by the Depositary prior to the Expiration Date; and (iii) in the 
case of a guarantee of Shares, the Certificates, in proper form for transfer, 
or a confirmation of a book-entry transfer of such Shares, if such procedure 
is available, into the Depositary's account at the Book-Entry Transfer 
Facility, together with a properly completed and duly executed Letter of 
Transmittal (or 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 this Letter of Transmittal, 
must be received by the Depositary within three Nasdaq National Market 
trading days after the date of execution of the Notice of Guaranteed 
Delivery, all as described in "Procedures for Accepting the Offer and 
Tendering Shares" of the Offer to Purchase. 

   THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, CERTIFICATES AND ALL 
OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER 
FACILITY, IS AT THE SOLE OPTION AND RISK OF THE TENDERING SHAREHOLDER, AND 
THE 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. 

   No alternative, conditional or contingent tenders will be accepted and no 
fractional Shares will be purchased. By execution of this Letter of 
Transmittal (or a facsimile hereof), all tendering shareholders waive any 
right to receive any notice of the acceptance of their Shares for payment. 

3. INADEQUATE SPACE. 

   If the space provided herein under "Description of Shares Tendered" is 
inadequate, the Certificate numbers, the number of Shares evidenced by such 
Certificates and the number of Shares tendered should be listed on a separate 
schedule and attached hereto. 

<PAGE>
4. PARTIAL TENDERS. 

   (Not applicable to shareholders who tender by book-entry transfer.) If 
fewer than all the Shares evidenced by any Certificate delivered to the 
Depositary herewith are to be tendered hereby, fill in the number of Shares 
which are to be tendered in the box entitled "Number of Shares Tendered." In 
such cases, new Certificate(s) evidencing the remainder of the Shares that 
were evidenced by the Certificates delivered to the Depositary herewith will 
be sent to the person(s) signing this Letter of Transmittal, unless otherwise 
provided in the box entitled "Special Delivery Instructions," as soon as 
practicable after the expiration or termination of the Offer. All Shares 
evidenced by Certificates delivered to the Depositary will be deemed to have 
been tendered unless otherwise indicated. 

5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS. 

   If this Letter of Transmittal is signed by the registered holder(s) of the 
Shares tendered hereby, the signature(s) must correspond with the name(s) as 
written on the face of the Certificates evidencing such Shares without 
alteration, enlargement or any other change whatsoever. 

   If any Shares tendered hereby are owned of record by two or more persons, 
all such persons must sign this Letter of Transmittal. 

   If any of the Shares tendered hereby are registered in the names of 
different holders, it will be necessary to complete, sign and submit as many 
separate Letters of Transmittal as there are different registrations of such 
Certificates. 

   If this Letter of Transmittal is signed by the registered holder(s) of the 
Shares tendered hereby, no endorsements of Certificates or separate stock 
powers are required, unless payment is to be made to, or Certificates 
evidencing Shares not tendered or not purchased are to be issued in the name 
of, a person other than the registered holder(s), in which case, the 
Certificate(s) evidencing the Shares tendered hereby must be endorsed or 
accompanied by appropriate stock powers, in either case signed exactly as the 
name(s) of the registered holder(s) appear(s) on such Certificate(s). 
Signatures on such Certificate(s) and stock powers must be guaranteed by an 
Eligible Institution. 

   If this Letter of Transmittal is signed by a person other than the 
registered holder(s) of the Shares tendered hereby, the Certificate(s) 
tendered hereby must be endorsed or accompanied by appropriate stock powers, 
in either case signed exactly as the name(s) of the registered holder(s) 
appear(s) on such Certificate(s). Signatures on such Certificate(s) and stock 
powers must be guaranteed by an Eligible Institution. 

   If this Letter of Transmittal or any Certificate(s) or stock power is 
signed by a trustee, executor, administrator, guardian, attorney-in-fact, 
officer of a corporation or other person acting in a fiduciary or 
representative capacity, such person should so indicate when signing, and 
proper evidence satisfactory to Purchaser of such person's authority so to 
act must be submitted. 

6. STOCK TRANSFER TAXES. 

   Except as otherwise provided in this Instruction 6, Purchaser will pay all 
stock transfer taxes with respect to the sale and transfer of any Shares to 
it or its order pursuant to the Offer. If, however, payment of the purchase 
price of any Shares purchased is to be made to, or Certificate(s) evidencing 
Shares not tendered or not purchased are to be issued in the name of, a 
person other than the registered holder(s), the amount of any stock transfer 
taxes (whether imposed on the registered holder(s), such other person or 
otherwise) payable on account of the transfer to such other person will be 
deducted from the purchase price of such Shares purchased, unless evidence 
satisfactory to Purchaser of the payment of such taxes, or exemption 
therefrom, is submitted. Except as provided in this Instruction 6, it will 
not be necessary for transfer tax stamps to be affixed to the Certificate(s) 
evidencing the Shares tendered hereby. 

7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. 

   If a check for the purchase price of any Shares tendered hereby is to be 
issued, or Certificate(s) evidencing Shares not tendered or not purchased are 
to be issued, in the name of a person other than the person(s) signing this 
Letter of Transmittal or if such check or any such Certificate is to be sent 
to someone other than the person(s) signing this Letter of Transmittal or to 
the person(s) signing this Letter of Transmittal but at an address other than 
that shown in the box entitled "Description of Shares Tendered," the 
appropriate boxes on this Letter of Transmittal must be completed. 
Shareholders tendering Shares hereby by book-entry transfer may request that 
Shares not purchased be credited to such 

<PAGE>
account maintained at the Book-Entry Transfer Facility as such shareholder 
may designate in the box entitled "Special Payment Instructions" on the 
reverse hereof. If no such instructions are given, all such Shares not 
purchased will be returned by crediting the account at the Book-Entry 
Transfer Facility as the account from which such Shares were delivered. 

8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. 

   Requests for assistance may be directed to the Information Agent at its 
respective address or telephone number set forth herein. Additional copies of 
the Offer to Purchase, this Letter of Transmittal, the Notice of Guaranteed 
Delivery and the Guidelines for Certification of Taxpayer Identification 
Number on Substitute Form W-9 may be obtained from the Information Agent or 
from brokers, dealers, commercial banks or trust companies. 

9. SUBSTITUTE FORM W-9. 

   Each tendering shareholder is required to provide the Depositary with a 
correct Taxpayer Identification Number ("TIN") on the Substitute Form W-9 
which is provided under "Important Tax Information" below, and to certify, 
under penalties of perjury, that such number is correct and that such 
shareholder is not subject to backup withholding of U.S. federal income tax. 
If a tendering shareholder has been notified by the Internal Revenue Service 
that such shareholder is subject to backup withholding, such shareholder must 
cross out item (2) of the Certification box of the Substitute Form W-9, 
unless such shareholder has since been notified by the Internal Revenue 
Service that such shareholder is no longer subject to backup withholding. 
Failure to provide the information on the Substitute Form W-9 may subject the 
tendering shareholder to 31% U.S. federal income tax withholding on the 
payment of the purchase price of all Shares purchased from such shareholder. 
If the tendering shareholder has not been issued a TIN and has applied for 
one or intends to apply for one in the near future, such shareholder should 
write "Applied For" in the space provided for the TIN in Part I of the 
Substitute Form W-9, and sign and date the Substitute Form W-9. If "Applied 
For" is written in Part I and the Depositary is not provided with a TIN 
within 60 days, the Depositary will withhold 31% on all payments of the 
purchase price to such shareholder until a TIN is provided to the Depositary. 

10. LOST, DESTROYED OR STOLEN CERTIFICATES. 

   If any Certificate(s) representing Shares has been lost, destroyed or 
stolen, the shareholder should promptly notify StockTrans, Inc. at Seven East 
Lancaster Avenue, Ardmore, Pennsylvania 19003-2318 (or by telephone at (610) 
649-7300 or facsimile at (610) 649-7302). The shareholder will then be 
instructed as to the steps that must be taken in order to replace the 
Certificate(s). This Letter of Transmittal and related documents cannot be 
processed until the procedures for replacing lost or destroyed certificates 
have been followed. 

   IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE HEREOF), PROPERLY 
COMPLETED AND DULY EXECUTED, WITH ANY REQUIRED SIGNATURE GUARANTEES, OR AN 
AGENT'S MESSAGE (TOGETHER WITH CERTIFICATES FOR SHARES OR CONFIRMATION OF 
BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR, IF APPLICABLE, A 
PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF GUARANTEED DELIVERY MUST BE 
RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE. 

                          IMPORTANT TAX INFORMATION 

   Under the U.S. federal income tax law, a shareholder whose tendered Shares 
are accepted for payment is required by law to provide the Depositary (as 
payer) with such shareholder's correct TIN on Substitute Form W-9 below. If 
such shareholder is an individual, the TIN is such shareholder's social 
security number. If the Depositary is not provided with the correct TIN, the 
shareholder may be subject to a $50 penalty imposed by the Internal Revenue 
Service. In addition, payments that are made to such shareholder with respect 
to Shares purchased pursuant to the Offer may be subject to backup 
withholding of 31%. 

   Certain shareholders (including, among others, all corporations and 
certain foreign individuals) are not subject to these backup withholding and 
reporting requirements. In order for a foreign individual to qualify as an 
exempt recipient, such individual must submit a statement, signed under 
penalties of perjury, attesting to such individual's exempt status. Forms of 
such statements can be obtained from the Depositary. See the enclosed 
Guidelines for Certification of Taxpayer Identification Number on Substitute 
Form W-9 for additional instructions. 

<PAGE>
   If backup withholding applies with respect to a shareholder, the 
Depositary is required to withhold 31% of any payments made to such 
shareholder. Backup withholding is not an additional tax. Rather, the tax 
liability of persons subject to backup withholding will be reduced by the 
amount of tax withheld. If withholding results in an overpayment of taxes, a 
refund may be obtained from the Internal Revenue Service. 

PURPOSE OF SUBSTITUTE FORM W-9 

   To prevent backup withholding on payments that are made to a shareholder 
with respect to Shares purchased pursuant to the Offer, the shareholder is 
required to notify the Depositary of such shareholder's correct TIN by 
completing the form below certifying (a) that the TIN provided on Substitute 
Form W-9 is correct (or that such shareholder is awaiting a TIN), and (b) 
that (i) such shareholder has not been notified by the Internal Revenue 
Service that such shareholder is subject to backup withholding as a result of 
a failure to report all interest or dividends or (ii) the Internal Revenue 
Service has notified such shareholder that such shareholder is no longer 
subject to backup withholding. 

WHAT NUMBER TO GIVE THE DEPOSITARY 

   The shareholder is required to give the Depositary the social security 
number or employer identification number of the record holder of the Shares 
tendered hereby. If the Shares are in more than one name or are not in the 
name of the actual owner, consult the enclosed Guidelines for Certification 
of Taxpayer Identification Number on Substitute Form W-9 for additional 
guidance on which number to report. If the tendering shareholder has not been 
issued a TIN and has applied for a number or intends to apply for a number in 
the near future, the shareholder should write "Applied For" in the space 
provided for the TIN in Part I, and sign and date the Substitute Form W-9. If 
"Applied For" is written in Part I and the Depositary is not provided with a 
TIN within 60 days, the Depositary will withhold 31% of all payments of the 
purchase price to such shareholder until a TIN is provided to the Depositary.

                                     (2) I am not subject to backup withholding because (a) I am exempt from backup
                                     withholding, (b) I have not been notified by the IRS that I am subject to

                                     notified by the IRS that you were subject to backup withholding you received

To Our Clients: 

   Enclosed for your consideration is an Offer to Purchase, dated August 14,
1998 (the "Offer to Purchase") and the related Letter of Transmittal (which, as
amended from time to time, together constitute the "Offer") in connection with
the Offer by LTI Merger, Inc., a Pennsylvania corporation ("Purchaser") and a
wholly owned subsidiary of Crane Co., a Delaware corporation ("Crane"), to
purchase all of the outstanding shares of common stock, par value $.01 per
share (the "Shares") of Liberty Technologies, Inc., a Pennsylvania corporation
(the "Company"), including the associated Preferred Stock Purchase Rights (the
"Rights") issued pursuant to the Amended and Restated Rights Agreement, dated
as of October 6, 1997 (the "Rights Agreement"), between the Company and
StockTrans, Inc., at a price of $3.50 per Share, net to the seller in cash,
without interest thereon, upon the terms and subject to the conditions set
forth in the Offer.

   THE MATERIAL IS BEING SENT TO YOU AS THE BENEFICIAL OWNER OF SHARES HELD BY
US FOR YOUR ACCOUNT BUT NOT REGISTERED IN YOUR NAME. WE ARE THE HOLDER OF
RECORD OF SHARES HELD BY US FOR YOUR ACCOUNT. A TENDER OF SUCH SHARES CAN BE
MADE ONLY BY US AS THE HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE
LETTER OF TRANSMITTAL IS FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT
BE USED BY YOU TO TENDER SHARES HELD BY US FOR YOUR ACCOUNT.

   We request instructions as to whether you wish to have us tender on your
behalf any or all of the Shares held by us for your account, upon the terms and
subject to the conditions set forth in the Offer.

   Your attention is directed to the following: 

   1. The tender price is $3.50 per Share, net to the seller in cash. 

   2. The Offer and withdrawal rights will expire at 12:00 Midnight, Eastern
time, on Friday, September 11, 1998, unless the Offer is extended.

   3. The Offer is being made for 100% of the outstanding Shares.

   4. The Offer is conditioned upon, among other things, Shares representing at
least a majority of the total number of outstanding Shares of Common Stock of
the Company on a fully diluted basis (assuming exercise of all outstanding
options to acquire Shares) being validly tendered and not withdrawn prior to
the expiration of the Offer.
<PAGE>
   5. 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 Purchaser
pursuant to the Offer.

   The Offer is made solely by the Offer to Purchase, and the related Letter of
Transmittal, and is being made to all holders of Shares. Purchaser is not aware
of any state where the making of the Offer is prohibited by administrative or
judicial action pursuant to any valid state statute. If Purchaser becomes aware
of any valid state statute prohibiting the making of the Offer or the
acceptance of Shares pursuant thereto, Purchaser will make a good faith effort
to comply with such state statute. If, after such good faith effort, Purchaser
cannot comply with such state statute, the Offer will not be made to (nor will
tenders be accepted from or on behalf of) the holders of Shares in such state.
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 shall be deemed to
be made on behalf of Purchaser by one or more registered brokers or dealers
licensed under the laws of such jurisdiction.

   If you wish to have us tender any or all of your Shares, please so instruct
us by completing, executing and returning to us the instruction form contained
in this letter. An envelope in which to return your instructions to us is
enclosed. If you authorize the tender of your Shares, all such Shares will be
tendered unless otherwise specified on the instruction form set forth in this
letter. YOUR INSTRUCTIONS SHOULD BE FORWARDED TO US IN AMPLE TIME TO PERMIT US
TO SUBMIT A TENDER ON YOUR BEHALF PRIOR TO THE EXPIRATION OF THE OFFER.

due to reasonable cause and not to willful neglect. 

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS--If you fail to 
include any portion of an includible payment for interest, dividends, or 
patronage dividends in gross income, such failure will be treated as being 
due to negligence and will be subject to a penalty of 20% on any portion of 
an underpayment attributable to that failure unless there is clear and 
convincing evidence to the contrary. 

(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING--If you 
make a false statement with no reasonable basis that results in no imposition 
of backup withholding, you are subject to a penalty of $500. 

(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Willfully falsifying 
certifications or affirmations may subject you to criminal penalties 
including fines and/or imprisonment.

                                                          FOR IMMEDIATE RELEASE



                CRANE CO. TO ACQUIRE LIBERTY TECHNOLOGIES, INC.


     STAMFORD,  CONNECTICUT  - AUGUST 12, 1998 - CRANE CO.  (NYSE:CR)  announced
that it had signed a definitive  merger  agreement  with  Liberty  Technologies,
Inc.,  providing for Crane's  acquisition  of all of the  outstanding  shares of
Liberty Technologies at $3.50 per share. There are 5,013,233 shares outstanding.

     Crane has also signed  agreements with shareholders  holding  approximately
19.6 percent of  Liberty's  outstanding  shares in which such  holders  agree to
tender their  shares in the offer.  In  addition,  Liberty has granted  Crane an
option to purchase up to 997,633 newly issued shares of Liberty  common stock at
$2.75 per share,  exercisable upon the termination of the merger agreement under
certain specified circumstances.
 
     Liberty Technologies,  Inc. which had sales in the first six months of 1998
of  $8.4  million  and  is   headquartered   in   Conshohocken,   PA,  develops,
manufactures,  markets and sells valve, motor,  engine and compressor  condition
monitoring  products  and related  services to  customers  in the nuclear  power
generation and industrial  process markets worldwide.  Liberty's  technology and
markets are very  complementary  with  Crane's  Nuclear  Valve  business,  which
provides valves, valve diagnostic  equipment,  and related valve services to the
nuclear  power  industry,  and with  Crane's  Dynalco  Controls  business  which
provides sensors,  instrumentation,  control products and automation systems for
use in industrial engine applications.

     The merger agreement provides for a cash tender offer by LTI Merger,  Inc.,
a Crane subsidiary,  for all outstanding Liberty  Technologies,  Inc., shares at
$3.50 per share. The consummation of the tender offer will be conditioned  upon,
among other  things,  there being duly  tendered  and not  withdrawn  at least a
majority of the then  outstanding  shares.  It is  contemplated  that the tender
offer will  commence on Monday,  August 17,  1998.  Any shares not  tendered and
purchased  pursuant to the tender offer will be acquired in a subsequent  merger
transaction at the same $3.50 cash price.

     Crane Co. is a diversified  manufacturer of engineered  industrial products
and the largest American distributor of doors, windows and millwork.

and subject to the conditions set forth in the Offer to Purchase dated August

(which together constitute the "Offer").

- -------------------------------------------------------------------------------
THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, EASTERN TIME, ON
           FRIDAY, SEPTEMBER 11, 1998, UNLESS THE OFFER IS EXTENDED.
- -------------------------------------------------------------------------------

         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.

         The Offer is conditioned upon, among other things, Shares representing
at least a majority of the total number of outstanding shares of Common Stock
of the Company on a fully diluted basis being validly tendered prior to the
expiration of the Offer and not properly withdrawn.

         The Offer is being made pursuant to an Agreement and Plan of Merger
dated as of August 11, 1998 (the "Merger Agreement") among Crane Co., a
Delaware corporation ("Crane"), the Purchaser and the Company. The Merger
Agreement provides, among other things, that as soon as practicable after the
consummation of the Offer, the Purchaser will be merged with and into the
Company (the "Merger"), with the Company continuing as the surviving
corporation. Pursuant to the Merger, each outstanding Share (other than Shares
held by Crane, the Purchaser or any other subsidiary of Crane or Shares held by
shareholders exercising dissenters' rights) will be converted into the right to
receive $3.50 in cash, without interest.

         The Offer is subject to certain conditions set forth in the Offer to
Purchase. If any such condition is not satisfied, the Purchaser may (i)
terminate the Offer and return all tendered Shares to tendering shareholders,
(ii) extend the Offer and, subject to withdrawal rights as set forth below,
retain all such Shares until the expiration of the Offer as so extended or
(iii) waive such condition and, subject to any requirement to extend the time
during which the Offer is open, purchase all Shares validly tendered prior to
the Expiration Date and not withdrawn. The Purchaser reserves the right, at any
time or from time to time, to extend the period of time during which the Offer
is open by giving oral or written notice of such extension to the Depositary.
Any such extension will be followed as promptly as practicable by public
announcement thereof.

         For purposes of the Offer, the Purchaser shall be deemed to have
accepted for payment tendered Shares when, as and if the Purchaser gives oral
or written notice to the Depositary of its acceptance of the tenders of such
Shares. Payment for Shares accepted for payment pursuant to the Offer will be
made only after timely receipt by the Depositary of certificates for such
Shares (or a confirmation of a book-entry transfer of such Shares into the
Depositary's account at the Book-Entry Transfer Facility (as defined in the
Offer to Purchase)), a properly completed and duly executed Letter of
Transmittal (or facsimile thereof) and any other required documents.

         Tenders of Shares made pursuant to the Offer may be withdrawn at any
time prior to the Expiration Date. Thereafter, such tenders are irrevocable,
except that they may be withdrawn after October 12, 1998 unless theretofore
accepted for payment as provided in the Offer to Purchase. To be effective, a
written, telegraphic, telex or facsimile transmission notice of withdrawal must
be timely received by the Depositary at one of its addresses set forth in the
Offer to Purchase and must specify the name of the person who tendered the
Shares to be withdrawn and the number of Shares to be withdrawn. If the Shares
to be withdrawn have been delivered to the Depositary, a signed notice of
withdrawal with (except in the case of Shares tendered by an Eligible
Institution (as defined in the Offer to Purchase)) signatures guaranteed by an
Eligible Institution must be submitted prior to the release of such Shares. In
addition, such notice must specify, in the case of Shares tendered by delivery
of certificates, the name of the registered holder (if different from that of
the tendering shareholder) and the serial numbers shown on the particular
certificates evidencing the Shares to be withdrawn or, in the case of Shares
tendered by book-entry transfer, the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Shares.

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

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

         The Offer to Purchase and Letter of Transmittal contain important
information which should be read before any decision is made with respect to
the Offer. Requests for copies of the Offer to Purchase and the related Letter
of Transmittal and other tender offer materials may be directed to the

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

         WHEREAS, also in furtherance of such acquisition, the respective

"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

         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

                                       3
<PAGE>

made by the Company with respect to information supplied by Crane or the
Purchaser in writing 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

                                       4
<PAGE>

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.

              (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.

         SECTION 1.08. Articles of Incorporation and By-laws. (a) The Second
Amended and Restated Articles of Incorporation of the Company attached hereto
as Exhibit 1 shall be the articles of incorporation of the Surviving
Corporation until thereafter changed or amended as provided therein or by
applicable law.

              (b) The By-laws of the Company as in effect at the Effective Time
shall be the by-laws of the Surviving Corporation until thereafter changed or
amended as provided therein or by applicable law.

         SECTION 1.09. Directors of the Surviving Corporation. The directors of
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
until their respective successors are duly elected and qualified, as the case
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.

                                       7
<PAGE>

              (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 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

                                       8
<PAGE>

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 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

                                       9
<PAGE>

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

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

Schedule sets forth a true and complete list of the Subsidiaries of the

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

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

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

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

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

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

                                      12
<PAGE>

              (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 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

                                      13
<PAGE>

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 was) a member of an affiliated group (other than the current
affiliated group of the Company and its

                                      14
<PAGE>

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.

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

         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

Disclosure Schedule is a list of (a) all contracts, agreements, commitments,

Effect with respect to the Company and its Subsidiaries, taken as a whole, or

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

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

its Subsidiaries has received any written notice or has any knowledge of any
pending, threatened or contemplated condemnation proceeding or assessment for

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

         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)

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 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 disposal of radioactive materials.

         SECTION 3.18. Products Liability. Other than ordinary course warranty
claims, during the past five years there have been no claims made against the
Company, its Subsidiaries or any Predecessor for personal injury, property
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 manner in which the Company and its Subsidiaries provide
coverage for workers' compensation claims and a list of all workers'
compensation claims filed against the Company or any of its Subsidiaries during
the past five years.

         SECTION 3.20 Employment and Change in Control Agreements. (a) Section
3.20 of the Company Disclosure Schedule sets forth a true and complete list of
all written, and to the

                                      20
<PAGE>

best knowledge of the Company, oral agreements with any officer, director or
employee of the Company or any of its Subsidiaries to which the Company or any
of its Subsidiaries is a party, providing for the terms of his or her
employment with the Company or any of its Subsidiaries and/or the terms of his
or her severance or other payments upon termination of such employment (the
"Employment Agreements"). The Company has previously furnished to Crane true
and complete copies of all Employment Agreements, together with all amendments
thereto (if any). 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
Subsidiaries (A) the benefits of which are contingent, or the terms of which
are materially altered, upon the occurrence of a transaction involving the
Company 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

                                      21
<PAGE>

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 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

                                      22
<PAGE>

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 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
made or incorporated by reference therein based on information supplied by
Crane specifically for inclusion or incorporation by reference in the Proxy
Statement.

         SECTION 3.25. Voting Requirements. The affirmative vote of the holders
of at least a majority of the votes cast by the holders of Company Common Stock
entitled to vote thereon (the "Company Shareholder Approval") is the only vote
of the holders of any class or series of the Company's capital stock necessary
to adopt this Agreement and to approve the transactions contemplated by this
Agreement.

         SECTION 3.26. State Statutes. The Board of Directors of the Company
has approved the terms of this Agreement, the Stock Option Agreement and the
Shareholders Agreements, the making of the Offer and the consummation of the
Merger and the other transactions contemplated by this Agreement, the Stock
Option Agreement and the Shareholder

                                      23
<PAGE>

Agreements and such approval renders the provisions of Section 2538 and
Subchapter F of Chapter 25 of the PBCL inapplicable to the transactions
contemplated by this Agreement, the Stock Option Agreement and the Shareholders
Agreements. To the best of the Company's knowledge, no other state takeover
statute or similar statute or regulation applies or purports to apply to this
Agreement, the Stock Option Agreement or the Shareholder Agreements or any of
the transactions contemplated hereby or thereby.

         SECTION 3.27. Rights Agreement. The Rights Agreement has been amended
as of the date hereof (i) to render the Rights Agreement inapplicable to this
Agreement, the Stock Option Agreement, the Shareholder Agreements, the Offer,
the Merger and the other transactions contemplated by this Agreement, the Stock
Option Agreement or the Shareholder Agreements and (ii) to ensure that (x)
neither Crane nor any of its wholly owned subsidiaries is an Acquiring Person
(as defined in the Rights Agreement) pursuant to the Rights Agreement, (y)
Crane and its wholly owned subsidiaries are Exempt Persons (as defined in the
Rights Agreement) pursuant to the Rights Agreement, and (z) a Stock Acquisition
Date, Distribution Date or Triggering Event (in each case as defined in the
Rights Agreement) does not occur solely by 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
connection with the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of the Company. The Company has provided
Crane with a true and correct copy of its engagement letter with Legg Mason
Wood Walker, Inc..

         SECTION 3.29. Disclosure. No representation or warranty of the Company
in this Agreement or any certificate, schedule, statement, document or
instrument furnished or to be furnished to Crane pursuant hereto or in
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.

<PAGE>

licensed to do 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

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
Agreement and to consummate the transactions contemplated by this Agreement.

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 consummation of the
transactions contemplated by this Agreement and compliance 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,

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

<PAGE>

necessitated by the Offer or the Merger or the transactions contemplated by
this Agreement; and (5) such consents, approvals, orders, authorizations,
registrations, declarations and filings the failure to make or obtain which

as a whole, or impair the ability of 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

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

              (xv) not increase the number of shares authorized or issued and

<PAGE>

              (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 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

becoming untrue, (ii) any of its representations and warranties that are not so
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

                                      29
<PAGE>

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, 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.

                                      30
<PAGE>

              (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

                                      31
<PAGE>

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 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 

                                      32
<PAGE>

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.

         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

                                      33
<PAGE>

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 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

                                      34
<PAGE>

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.

                                   ARTICLE VI
                              CONDITIONS PRECEDENT

         SECTION 6.01. Conditions to Each Party's Obligation To Effect the
Merger. The respective obligation of each party to effect the Merger is subject
to the satisfaction on or prior to the Closing Date of the following
conditions:

have been obtained, if required by applicable law.

              (b) HSR Act. The waiting period (and any extension thereof)
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

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;

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

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 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

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

party of any of its representations, warranties, covenants or agreements set

any termination of this Agreement.

                             STOCK OPTION AGREEMENT


         THIS STOCK OPTION AGREEMENT, dated as of August 11, 1998
("Agreement"), between Liberty Technologies, Inc., a Pennsylvania corporation
(the "Company"), and Crane Co., a Delaware corporation ("Crane");

                              W I T N E S S E T H:

         WHEREAS, the Company, Crane and LTI Merger, Inc., a Pennsylvania
corporation and wholly owned subsidiary of Crane ("Merger Sub"), propose to
enter into an Agreement and Plan of Merger, of even date herewith (the "Merger
Agreement"), which provides that, among other things, upon the terms and
subject to the conditions thereof, Merger Sub will be merged with and into the
Company, with the Company continuing as the surviving corporation; and

         WHEREAS, as a condition to the willingness of Crane to enter into the
Merger Agreement, Crane has required that the Company agree, and in order to
induce Crane to enter into the Merger Agreement, the Company has agreed, to
grant Crane an option to purchase certain shares of the common stock of the
Company together with the Rights associated therewith, in accordance with the
terms of this Agreement;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein and in the Merger Agreement, and
intending to be legally bound, the parties hereto agree as follows:


                                   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
    STATE LAWS, AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER."

Adverse Effect on Crane.


                                  ARTICLE III

                            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

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

                                      -5-

Securities. The Company shall indemnify and hold harmless Crane, its affiliates
and controlling persons and their respective officers, directors, agents and
representatives from and against any and all losses, claims, damages,
liabilities and expenses (including, without limitation, all out-of-pocket
expenses, investigation expenses, expenses incurred with respect to any
judgment 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.

                             SHAREHOLDER AGREEMENT

         THIS SHAREHOLDER AGREEMENT, dated as of August 11, 1998 (this
"Agreement"), between Crane Co., a Delaware corporation ("Crane"), and the
shareholder listed on the signature page hereof (such shareholder and (with
respect to Shares (as defined herein) owned by an individual jointly with such
shareholder's spouse) together with his or her spouse, being referred to herein
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
corporation (the "Company"), set forth below the name of the Shareholder on the
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.

         Section 2. Voting of Shares; Proxy. (a) The Shareholder agrees that
until the earlier of (i) the Effective Time, (ii) the date on which the Merger
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

<PAGE>

in favor of the transactions contemplated by the Merger Agreement as such
Merger Agreement may be modified or amended from time to time and (y) against
any action, omission 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
         "SHAREHOLDER AGREEMENT")."

         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 for the option granted to Crane pursuant to Section 4 hereof,
         not sell, transfer, pledge, hypothecate, encumber, assign, tender or
         otherwise dispose of, or enter into any contract, option or other
         arrangement or understanding with respect to the sale, transfer,
         pledge, hypothecation, encumbrance, assignment, tender or other
         disposition of, any of the Shares 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"

                                       2
<PAGE>

         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;

              (b) until the Expiration Date, except as may be required to vote
         the Shares in accordance with Section 2 hereof, not grant any powers
         of attorney or proxies or consents in respect of any of the Shares
         owned by such Shareholder, deposit any of the Shares owned by such
         Shareholder into a voting trust, enter into a voting agreement with
         respect to any of the Shares owned by such Shareholder or otherwise
         restrict the ability of the holder of any of the Shares owned by such
         Shareholder freely to exercise all voting rights with respect thereto;
         and

              (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

                                       3
<PAGE>

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.

         Section 5. Covenants of Crane. Crane covenants and agrees for the
benefit of the Shareholder that (a) immediately upon execution of this
Agreement, Crane shall enter into the Merger Agreement, and (b) until the
Expiration Date, it shall use all reasonable efforts to take, or cause to be
taken, all action, and do, or cause to be done, all things necessary or
advisable in order to consummate and make effective the transactions
contemplated by this Agreement and the Merger Agreement, consistent with the
terms and conditions of each such agreement; provided, however, that nothing in
this Section 5, Section 14 or any other provision of this Agreement is
intended, nor shall it be construed, to limit or in any way restrict Crane's
right or ability to exercise any of its rights under the Merger Agreement.

         Section 6. Representations and Warranties of the Shareholder. The
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 accordance with its terms, subject to the effect of bankruptcy,
insolvency, 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

                                       4
<PAGE>

including the earlier to occur of the date that is six months after the
Expiration Date or the date of the consummation of any transfer of Shares
permitted by Section 3(a) hereof.

         Section 7. Adjustments; Additional Shares. In the event (a) of any
stock dividend, stock split, merger (other than the Mergers) recapitalization,
reclassification, combination, exchange of shares or the like of the capital
stock of the Company on, of or affecting the Shares or (b) that the Shareholder
shall become the beneficial owner of any additional shares of 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 and the
terms of this 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 hereunder.

         Section 8. Specific Performance. The Shareholder acknowledges that 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.

         Section 9. Notices. All notices, requests, claims, demands and other
communications hereunder shall be effective upon receipt (or refusal of
receipt), shall be in writing and shall be delivered in person, by telecopy or
telefacsimile, by telegram, by next-day courier service, or by mail (registered
or certified mail, postage prepaid, return receipt requested) to the
Shareholder at the address listed on the signature page hereof, and to Crane at
100 First Stamford Place, Stamford, CT 06902, Attention: Augustus I. duPont,
telecopy number 203-363-7350 or to such other address or telecopy number as any
party may have furnished to the other in writing in accordance herewith.

         Section 10. Binding Effect; Survival. Upon execution and delivery of
this Agreement by Crane, this Agreement shall become effective as to the
Shareholder at the time the Shareholder executes and delivers this Agreement.
This Agreement shall inure to the benefit of and be binding upon the parties
hereto and their respective heirs, personal representatives, successors and
assigns.

         Section 11. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of Pennsylvania
applicable to agreements made and to be performed entirely within such
Commonwealth.

         Section 12. Counterparts. This Agreement may be executed in two
counterparts, both of which shall be an original and both of which together
shall constitute one and the same agreement.

         Section 13. Effect of Headings; Defined Terms. The Section headings
herein are for convenience of reference only and shall not affect the
construction hereof. Capitalized terms used but not defined herein shall have
the meanings assigned thereto in the Merger Agreement.

         Section 14. Additional Agreements; Further Assurance. Subject to the
terms and conditions herein provided, each of the parties hereto agrees to use
all reasonable efforts to take, or cause to be taken, all action and to do, or
cause to be done, all things necessary, proper or advisable to consummate and
make effective the transactions contemplated by this Agreement. The Shareholder
will provide Crane with all documents which may reasonably be requested by
Crane and will take reasonable steps to enable Crane to obtain all rights and
benefits provided it hereunder.

         Section 15. Amendment; Waiver. No amendment or waiver of any provision
of this Agreement or consent to departure therefrom shall be effective unless
in writing and signed by Crane and the Shareholder, in the case of an
amendment, or by the party which is the beneficiary of any such provision, in
the case of a waiver or a consent to depart therefrom.

         IN WITNESS WHEREOF, this Agreement has been duly executed by the
parties hereto all as of the day and year first above written.

                               FIRST AMENDMENT TO
                     AMENDED AND RESTATED RIGHTS AGREEMENT


    This First Amendment (this "Amendment") to the Amended and Restated Rights

    and LTI Merger, Inc., a Pennsylvania corporation and a wholly-owned
    subsidiary of Crane ("Merger Sub"))(the earlier of (i) and (ii) being the
    "Expiration Date"), the registered holder of any Rights Certificate may,
    subject to the provisions of Sections 7(e) and 9(c), exercise the Rights
    evidenced thereby in whole or in part at any time after the Distribution
    Date upon surrender of the Rights Certificate, with the form of election to

    pursuant to Section 7, 11 or 13 of this Agreement by reason of (i) the
    approval, execution, delivery or effectiveness of the Merger Agreement, the
    Stock Option Agreement (as defined in the Merger Agreement) or the
    Shareholder Agreements (as defined in the Merger Agreement) or (ii) the
    consummation of any of the transactions contemplated by the Merger
    Agreement, the Stock Option Agreement or Shareholder Agreements in
    accordance with the terms thereof or the taking of any action by any party
    thereto or any Affiliate or Associate thereof to facilitate the
    consummation of any such transactions."

4.  Capitalized terms not otherwise defined herein shall have the meanings
ascribed to them in the Rights Agreement.

5.  This Amendment shall be deemed effective as of August 11, 1998, as if

Agreement shall remain unchanged and shall remain in full force and effect.

6.  This Amendment may be executed in two counterparts, each of which shall be
