Item 2. Acquisition or Disposition of Assets

     On November 24, 1998 (the "Closing Date"), PubliCARD, Inc. ("PubliCARD"
or the "Company") completed the acquisition of  Tritheim Technologies, Inc.
("Tritheim") pursuant to an Agreement and Plan of Merger dated as of October
30, 1998 (the "Merger Agreement") whereby a wholly-owned subsidiary of the
Company merged with and into Tritheim.  As a result of this merger, Tritheim
became a wholly-owned subsidiary of the Company.  As consideration in the
merger, holders of Tritheim's common stock received a total of 1,495,037
shares of common stock of the Company in exchange for their shares of common
stock of Tritheim.  Marc Postlewaite, President of Tritheim, and Kim Vogel,
Vice President - Engineering of Tritheim, held shares representing 74% of
Tritheim's outstanding common stock.  

     In addition, pursuant to the Merger Agreement options to purchase
354,616 shares of Tritheim common stock outstanding immediately prior to the
closing of the merger (a portion of which were held by Marc Postlewaite and
Kim Vogel) were converted into options to purchase 83,270 shares of PubliCARD
common stock with an exercise price of $2.00 per share (subject to anti-
dilution adjustments).  These PubliCARD options are exercisable from the
Closing Date until the fifth anniversary of the Closing Date.  Furthermore,
pursuant to the Merger Agreement, the Company issued on the Closing Date
options to purchase 250,000 shares of PubliCARD common stock to all of the
salaried employees of Tritheim to encourage them to remain in the employ of
Tritheim.  These options have an exercise price of $2.00 per share (subject to
anti-dilution adjustments) and will be exercisable from the third anniversary
of the Closing Date until the eighth anniversary of the Closing Date.

     The merger consideration was determined as a result of arms length
negotiations between the Company and Tritheim.  The merger will be accounted
for under the purchase method of accounting.

     Pursuant to the Merger Agreement, the Company is required to register
the shares of PubliCARD common stock issued as the merger consideration (other
than the approximately 1,253,771 shares issued to officers of Tritheim and one
additional employee of Tritheim), approximately 241,266 shares, under a shelf
registration statement under the Securities Act of 1933.  In the event that
the shelf registration statement is not effective by the six month anniversary
of the Closing Date, the holders of the shares entitled to such registration
rights will have the right, for a specified period of time, to cause the
Company to repurchase their shares for a cash purchase price equal to the fair
market value (as defined in the Merger Agreement) of the shares on the date of
repurchase.  

     Pursuant to the Merger Agreement, the Company satisfied Tritheim's
indebtedness, including accrued interest, to a bank in the amount of $102,000
and to former shareholders of Tritheim in the amount of $531,000 (including
$480,000 to Marc Postlewaite).  The repayment of certain indebtedness of
Tritheim by the Company was financed with available cash on hand.  

     Pursuant to the Merger Agreement, Tritheim entered into separate
employment agreements with three-year terms with the following officers and
former shareholders of Tritheim: (1) Marc Postlewaite to serve as President of
Tritheim, (2) Kim Vogel to serve as Vice President - Engineering of Tritheim,
(3) Vincent Poole to serve as Vice President - Product Development of Tritheim
and (4) Stephen Ewald to serve as Vice President - Sales and Marketing of
Tritheim.

     Other than the Merger Agreement, a $300,000 loan made by PubliCARD to
Tritheim on September 18, 1998 and the employment agreements and stock option
agreements entered into pursuant to the Merger Agreement and described herein,
there are no material relationships between Tritheim or any of Tritheim's
former shareholders and PubliCARD or any of PubliCARD's affiliates, directors
or officers. 

     Tritheim, located in Tarpon Springs, Florida, has developed both 
hardware and software smart card products.  Its hardware products
include serial, parallel and PCMCIA smart card readers, smart port docking
stations and smart card reader chipsets. Its software products include smart
card software development tools for developing smart card applications, PC
security software, Internet data security smart card software, Internet
purchase terminal software and Internet automatic teller software.

                   another national securities exchange), the Fair Market
                   Value of such class stock is the average of the
                   closing quotations for such stock based on composite
                   transactions for the New York Stock Exchange (or if

                   exchange) for the five Trading Days ending at the
                   close of business on the day prior to such given date.

                   (b)  If the class of stock is not traded on any national

                   stock is the average of the last sales price (if the
                   stock is then listed as a national market issue under
                   the NASDAQ System) or the mean between the closing
                   representative bid and asked prices (in all other
                   cases) for the stock as reported by the NASDAQ System
                   (or such similar quotation system) for the five
                   Trading Days ending at the close of business on the

                   of such valuation date, as determined by the Board of
                   Directors of the issuer of such stock in good faith
                   and in accordance with uniform principles consistently
                   applied.

                   may be prosecuted as if such Merger had not taken

         (c)  Conversion of Shares.  As of the Effective Time, by virtue of the
         Merger and without any further action on the part of Publicker,
         Acquisition Sub, the Company, or any holder of any equity

                   (a)  each Company Share issued and outstanding immediately
                   prior to the Effective Time shall be converted into
                   the right to receive that number of Publicker Shares
                   (the "Merger Consideration") as determined by dividing
                   (x) 1,495,000 by (y) the aggregate number of Company
                   Shares issued and outstanding immediately prior to the
                   Effective Time, upon surrender of the certificates
                   representing such Company Shares to Publicker;
                   provided, however, that if Publicker determines, based
                   on its review of Investor Questionnaires in
                   substantially the form of Exhibit H delivered to
                   Publicker by the holders of Company Shares, that the
                   issuance of Publicker Shares as the Merger
                   Consideration to any holder of Company Shares may
                   cause the Contemplated Transactions to fail to comply
                   with applicable securities laws, then, at Publicker's
                   option, each outstanding Company Share held by such
                   holder shall be converted into the right to receive
                   cash in amount equal to (A) the Fair Market Value at
                   the Effective Time of 1,495,000 Publicker Shares
                   divided by (B) the aggregate number of Company Shares
                   issued and outstanding immediately prior to the
                   Effective Time (any such cash payable per Company
                   Share shall also be referred to herein as the "Merger
                   Consideration");

                   (b)  if on or before the Effective Date the issued and
                   outstanding Publicker Shares are changed into a
                   different number of shares by reason of any
                   recapitalization, stock split or stock dividend, then
                   the Merger Consideration shall be correspondingly
                   adjusted as follows:  (i) to the extent the Merger
                   Consideration consists of Publicker Shares, the Merger
                   Consideration shall be adjusted to that number of
                   Publicker Shares that the Merger Consideration, if it
                   was issued and outstanding immediately before any such
                   recapitalization, stock split or stock dividend
                   occurred, would have been converted into as a result
                   of any such recapitalization, stock split or stock
                   dividend and (ii) to the extent the Merger
                   Consideration consists of cash, the Merger
                   Consideration shall be adjusted to a cash amount
                   determined based on the Fair Market Value of that
                   number of Publicker Shares that 1,495,000 Publicker
                   Shares, if they were issued and outstanding
                   immediately before any such recapitalization, stock
                   split or stock dividend occurred, would have been
                   converted into as a result of any such
                   recapitalization, stock split or stock dividend;

                   (c)  no fraction of a Publicker Share will be issued, but
                   in lieu thereof each holder of Company Shares who
                   would otherwise be entitled to a fraction of a
                   Publicker Share (after aggregating all fractional
                   Publicker Shares to be received by such holder) shall
                   receive from Publicker one additional Publicker Share;

                   (d)  each share of common stock, $.01 par value per share,
                   of Acquisition Sub issued and outstanding immediately
                   prior to the Effective Time shall be converted into
                   and exchanged for one validly issued, fully paid and
                   nonassessable share of common stock, $.01 par value
                   per share, of the Surviving Corporation;

                   (e)  all Company Shares by virtue of the Merger and without
                   any action on the part of the holders thereof, shall
                   no longer be outstanding and shall be canceled and
                   retired and shall cease to exist, and each holder of a
                   certificate representing any Company Shares shall
                   thereafter cease to have any rights with respect to
                   such Company Shares, except the right to receive the
                   Merger Consideration for the Company Shares upon the
                   surrender of such certificate in accordance with this
                   Section 2.3;

                   (f)  each outstanding option to purchase Company Shares, by
                   virtue of the Merger and without any action on the
                   part of the holders thereof, shall be assumed by
                   Publicker and shall be converted into the right to
                   receive an option to purchase Publicker Shares in an
                   amount and with an exercise price as set forth on
                   Schedule 2.3(f) and otherwise substantially in the
                   form of Exhibit E-1;

                   (g)  if on or before the Effective Date the issued and
                   outstanding Publicker Shares are changed into a
                   different number of shares by reason of any
                   recapitalization, stock split or stock dividend, then
                   the Publicker Shares issuable upon exercise of each of
                   the options described in Section 2.3(f) and on
                   Schedule 2.3(f) shall be correspondingly adjusted to
                   that number of Publicker Shares that such Publicker
                   Shares, if they were issued and outstanding
                   immediately before any such recapitalization, stock
                   split or stock dividend occurred, would have been
                   converted into as a result of any such
                   recapitalization, stock split or stock dividend;

                   (h)  either prior to or promptly following the Effective
                   Time, Publicker shall deliver to each shareholder of
                   record of the Company immediately prior to the
                   Effective Time a letter of transmittal in
                   substantially the form of Exhibit G (each, a "Letter
                   of Transmittal") and instructions for use in
                   surrendering the certificates that formally
                   represented Company Shares entitled to payment of the
                   Merger Consideration.  Promptly following proper
                   delivery of a certificate representing Company Shares
                   (accompanied by a duly executed Letter of Transmittal
                   and the documents contemplated thereby) by the holder
                   thereof to Publicker, Publicker shall deliver to such
                   holder either (i) a certificate representing (A) the
                   Merger Consideration (in terms of Publicker Shares)
                   times the number of Company Shares represented by the
                   certificate so delivered by such holder and (B) any
                   additional Publicker Share issuable in lieu of any
                   fractional Publicker Share issuable to such holder in
                   accordance with Section 2.3(c), or (ii) cash in amount
                   equal to the Merger Consideration (in terms of cash)
                   times the number of Company Shares represented by the
                   certificate so delivered by such holder, whichever is
                   applicable pursuant to Section 2.3(a); and

                   (i)  if the Merger Consideration is to be issued or paid
                   (as the case may be) to a name other than the name in
                   which the certificate representing the Company Shares
                   surrendered in exchange therefor is registered, it
                   shall be a condition to such issuance or payment that
                   the person requesting such issuance or payment shall
                   pay to Publicker any transfer or other taxes required
                   by reason of the issuance of such shares or the
                   payment of such cash to a name other than that of the
                   registered holder of the certificate surrendered, or
                   such person shall establish to the satisfaction of
                   Publicker that such tax has been paid or is not
                   applicable.

         (d)  Subsequent Action.  If, at any time after the Effective Time, the
         Surviving Corporation shall consider or be advised that any deeds,
         bills of sale, assignments, assurances and any other actions or
         things are necessary, desirable or proper to vest, perfect or
         confirm, of record or otherwise, in the Surviving Corporation its

         properties or assets of the Constituent Corporations as a result
         of, or in connection with, the Merger, the officers and directors

         The Company and Management Sellers hereby jointly and severally
represent and warrant to Publicker and Acquisition Sub as follows:

         (a)  Organization and Good Standing.  The Company is a corporation duly
         organized, validly existing and in good standing under the laws of
         the State of its incorporation.  The Company (a) has all requisite
         corporate power to own, operate and lease its properties and carry
         on its business as the same is now being conducted and (b) is
         qualified to do business as a foreign corporation in each
         jurisdiction set forth in Schedule 6.1.  Neither the location of
         its property nor the conduct of its business requires the Company
         to be qualified to do business as a foreign corporation in any
         state, other than those in which it is so qualified, where the
         failure to so qualify would have a Material Adverse Effect.  The
         Company has delivered to Publicker true and complete copies of the
         articles or certificate of incorporation and bylaws of the
         Company.

             (b)  Capitalization of the Company; Subsidiaries.

              (a)  The authorized capital stock of the Company consists of
              10,000,000 shares of common stock, no par value per share,
              of which 6,367,765.06 shares are issued and outstanding. 
              The outstanding Company Shares have been duly authorized and
              validly issued and are fully paid and nonassessable and are
              owned of record and, to the knowledge of Management Sellers,
              beneficially as shown on Schedule 6.2(a).  The outstanding
              Company Shares were issued in conformity with applicable
              laws and not in violation of any preemptive rights of any
              Person.

              (b)  The Company does not have and has never had any
              Subsidiaries.

              (c)  Except as set forth on Schedule 6.2(c), there are no
              outstanding subscriptions, options, rights, warrants, con-
              vertible securities or other agreements (other than this
              Agreement) or calls, demands or commitments of any kind
              relating to the issuance, sale or transfer of any capital
              stock of the Company.  None of the items set forth on
              Schedule 6.2(c) will survive the Closing.

             (c)  Authority; Absence of Conflict.

              (a)  The Company has full corporate authority to execute, deliver
              and perform this Agreement and each other agreement,
              document or instrument required to be delivered by it hereby
              or in connection herewith (collectively, the "Company
              Documents") and to consummate the Contemplated Transactions. 
              The execution, delivery and performance by the Company of
              the Company Documents and the consummation of the
              Contemplated Transactions has been duly authorized by the
              board of directors of the Company and, on the Closing Date,
              will be duly authorized by the shareholders of the Company,
              and no other corporate proceedings on the part of the
              Company are necessary to authorize the Company Documents or
              the Contemplated Transactions.  This Agreement has been, and
              each other Company Document when executed and delivered in
              accordance with this Agreement will be, duly executed and
              delivered by the Company.  This Agreement constitutes, and
              each of the other Company Documents when executed and
              delivered in accordance with this Agreement will constitute,
              a valid and binding obligation of the Company, enforceable
              against the Company in accordance with its terms.

              (b)  Neither the execution and delivery of the Company Documents,
              nor the consummation of the Contemplated Transactions will
              (i) violate, be in conflict with or constitute a default (or
              an event which, with notice or lapse of time or both, would
              constitute a default) under, or provide the basis of
              termination of, or cause the acceleration of the performance
              required by, any agreement, commitment or instrument to
              which the Company is a party or by which any of its prop-
              erties or assets is bound or (ii) violate any statute or law
              or any judgment, decree, order, regulation or rule of any
              court or other Governmental Body applicable to the Company,
              or (iii) result in any Encumbrance upon any of the
              properties or assets of the Company under any agreement,
              commitment or instrument to which the Company is a party or
              by which the Company or any of its properties or assets may
              be bound, or (iv) violate or be in conflict with any
              provision of the certificate or articles of incorporation or
              bylaws of the Company.

         (d)  Consents and Approvals.  Schedule 6.4 lists (i) all consents,
         approvals and authorizations of, and declarations, filings and
         registrations with, any Governmental Body and (ii) all consents of
         other Persons (including, but not limited to, any party to a lease
         or other agreement or commitment of the Company), which are
         required by or on behalf of the Company in connection with the
         execution, delivery and performance of the Company Documents or
         the consummation of the Contemplated Transactions.

         (e)  Financial Statements.  The Company has delivered to Publicker
         (a) an unaudited balance sheet of the Company at December 31,
         1997, and the related unaudited profit and loss statement for the
         fiscal year then ended and (b) an unaudited balance sheet of the
         Company at August 31, 1998, and the related unaudited profit and
         loss statement for the nine months then ended (collectively the
         "Financial Statements").  The Financial Statements have been
         prepared on a modified cash basis and fairly present the financial
         position of the Company at the respective dates thereof and for
         the periods referred to therein, subject to the exceptions set
         forth on Schedule 6.5. 

         (f)  Accounts Receivable.  The accounts receivable of the Company

         usual course of business in connection with bona fide transactions
         and consistent with past practice, (b) as of August 31, 1998,

         properly accrued in accordance with GAAP and any reserves or
         allowances for doubtful accounts have been properly accrued in
         accordance with GAAP.

         (g)  Title to Property; Encumbrances.  The Company owns no real
         property other than the facilities identified on Schedule 6.7. 
         The Company has good and marketable title to such facilities, free
         of any Encumbrances other than Permitted Encumbrances.  The
         Company has delivered or made available to Publicker true and
         complete copies of the deeds and other instruments by which the
         Company acquired such real property and all title insurance
         policies, opinions, abstracts and surveys which relate to such
         real property and are in the possession of the Company.  Except
         for Permitted Encumbrances, the Company has good title to all of
         the material personal property reflected as being owned by it on
         the balance sheets included in the Financial Statements (except
         for personal property sold or otherwise disposed of since the
         dates of such balance sheets (as applicable) in the ordinary
         course of business).  As used herein, "Permitted Encumbrances"
         means (a) those Encumbrances disclosed on the balance sheets
         included in the Financial Statements or the notes thereto;
         (b) statutory liens for current taxes or assessments not yet due
         or delinquent or the validity of which are being contested in good
         faith by appropriate proceedings (a list of all such proceedings
         as of the date of this Agreement being included on Schedule 6.7);
         (c) mechanics', carriers', workers', repairmen's and other similar
         liens arising or incurred in the ordinary course of business with
         respect to charges not yet due and payable; (d) recorded easements
         for public utilities serving the Company's real property;
         (e) zoning, building and other similar restrictions; and (f) such
         other Encumbrances, if any, which do not materially detract from
         the value of or interfere with the present use, or any use
         presently anticipated by the Company, or materially and adversely
         affect the marketability of the property subject thereto or
         affected thereby.

         (h)  Leased Property.  Schedule 6.8 sets forth a true and complete list
         of, and the Company has delivered or made available to Publicker
         true and complete copies of, each lease under which the Company is
         a lessee or lessor (other than leases for personal property having
         a value per item or aggregate payments of less than $10,000 per
         annum).  There is not, with respect to any such lease, any
         existing event of default, or event which (with notice or lapse of
         time or both) would constitute an event of default, on the part of
         the Company, and the Company has not received any written notice
         of any such event.  The Company enjoys peaceful and undisturbed
         possession under each such lease.  None of the rights of the
         Company under any lease set forth on Schedule 6.8 will be subject
         to termination or modification and no consent or approval of any
         third party is required under such leases as a result of the
         consummation of the Contemplated Transactions.

             (i)  Intellectual Property Rights. 

              (a)  Schedule 6.9(a) contains a true and complete list of all
              Intellectual Property (as defined in clause (m) below),

              registrations with or in any Governmental Body having
              jurisdiction over such subject matter.  All such
              applications, filings and registrations have been duly
              filed, and those registrations which have issued are validly
              existing and in full force and effect and all required
              maintenance and annuity fees have been paid in full.  With
              respect to all U.S. registered service and trademarks,
              Section 8 and 15 declarations, where applicable, have been
              timely filed and accepted.  No service or trademarks listed
              on Schedule 6.9(a) have been abandoned.

              (b)  Except as specifically set forth on Schedule 6.9(b), the
              Company has good and marketable title to all Intellectual

              any royalties, license fees or other amounts.

              (c)  Except as specifically set forth on Schedule 6.9(c), (i)
              there are no licenses, agreements, obligations or other
              commitments by which the Company may be bound from or with
              third parties under which the Company uses, has the right to
              use or exercises any rights with respect to any Intellectual
              Property or Technology and (ii) there are no judicial
              orders, decrees, judgments or stipulations restricting the
              Company's use or right to use any Intellectual Property or
              Technology.

              (d)  Except as set forth on Schedule 6.9(d), the Company has not
              received (and the Company has no knowledge of) any notice,
              claim or allegation from any other party challenging the
              right of the Company to use, possess, transfer, convey or
              otherwise dispose of any Intellectual Property or
              Technology.  Except as set forth on Schedule 6.9(d), there
              is no interference, opposition, cancellation, reexamination
              or other contest proceeding, action, claim, dispute or claim
              of infringement, misappropriation or other violation of any
              intellectual property or other proprietary rights of any
              other party.  The Company's use of the Intellectual Property
              and Technology, past and present, has not and does not
              violate or infringe upon the rights of any other party or
              constitute a breach of any agreement, obligation, promise or
              commitment by which the Company may be bound or constitute a
              violation of any laws, regulations, ordinances, codes or
              statutes in any jurisdiction.

              (e)  Except as set forth on Schedule 6.9(e), no licenses or other
              rights have been granted and the Company has no obligation
              to grant licenses with respect to any Intellectual Property
              or Technology.  No claims have been made by or against the
              Company of any violation or infringement by others of any
              rights with respect to any Intellectual Property or
              Technology.  The Company is not aware of any such claim
              which the Company may have the right or a reasonable basis
              to make or assert.

              (f)  Except as set forth on Schedule 6.9(f), the Intellectual
              Property and Technology includes all rights and interests

         basis exists for any such Proceeding.  There are no existing
         judgments, orders, writs, injunctions, awards or decrees of any
         court or other Governmental Body against the Company or its

         (n)  Tax Matters.  Except as otherwise disclosed on Schedule 6.14:

                   (a)  The Company has, at all times since its formation,
                   qualified as an S corporation (as defined under
                   Section 1361(a)(1) of the Code) for federal, state and
                   local tax purposes and has timely and properly made
                   all elections necessary to obtain (or retain) such S
                   corporation status.  The Company has timely filed or
                   caused to be timely filed all Tax Returns that are or
                   were required to be filed by or with respect to it
                   pursuant to applicable legal requirements.  All such
                   Tax Returns are true, correct and complete. 
                   Management Sellers have delivered or made available to
                   Publicker copies of, and Schedule 6.14(a) contains a
                   complete and accurate list of, all such Tax Returns
                   relating to income or franchise taxes filed since
                   December 31, 1994.  The Company has paid all Taxes
                   that have or may have become due pursuant to those Tax
                   Returns or otherwise, or pursuant to any assessment
                   received by Sellers or the Company, except such Taxes,
                   if any, as are listed on Schedule 6.14(a) and are
                   being contested in good faith and as to which adequate
                   reserves have been provided in the audited balance
                   sheet included in the Financial Statements.  The
                   Company has not been a member of a group of
                   corporations and has not owned 80 percent or more of
                   any shares of stock of any other corporation.

                   (b)  The Tax Returns of the Company have been audited by
                   the Internal Revenue Service or other relevant
                   Governmental Body or are closed by the applicable
                   statute of limitations for all taxable years through
                   December 31, 1994.  Schedule 6.14(b) contains a
                   complete and accurate list of all audits of all such
                   Tax Returns, including a reasonably detailed
                   description of the nature and outcome of each audit. 
                   No adjustments have been proposed with respect to the
                   Tax Returns filed by the Company for all taxable years
                   since December 31, 1994.  None of Sellers or the
                   Company has given or been requested to give waivers or
                   extensions (or is or would be subject to a waiver or
                   extension given by any other Person) of any statute of
                   limitations relating to the payment of Taxes by it or
                   for which it may be liable.

                   (c)  The charges, accruals, and reserves with respect to
                   Taxes on the books of the Company are adequate and are
                   at least equal to the Company's liability for Taxes. 
                   There exists no proposed tax assessment against the
                   Company except as disclosed in the audited balance
                   sheet included in the Financial Statements.  No
                   consent to the application of Section 341(f)(2) of the
                   Code has been filed with respect to any property or
                   assets held, acquired, or to be acquired by the
                   Company.  All Taxes that the Company is or was
                   required by legal requirements to withhold or collect
                   have been duly withheld or collected and, to the
                   extent required, have been paid to the proper
                   Governmental Body.

                   (d)  There is no tax sharing agreement that will require
                   any payment by the Company after the date of this
                   Agreement.

                   tax under Section 103 of the Code.

                   (f)  The Company is not and has not been a United States
                   real property holding corporation within the meaning
                   of Section 897(c)(2) of the Code.

                   (g)  There is no agreement, plan, arrangement or other
                   contract covering any employee or independent
                   contractor or former employee or former independent
                   contractor of the Company that could give rise to the
                   payment of any amount that could not be deductible
                   pursuant to Section 280G of the Code.

                   (h)  The Company (i) has complied with all applicable legal
                   requirements relating to information reporting with

                   timely withheld from employee wages and other payments
                   and paid over to the proper Governmental Bodies all
                   amounts required to be so withheld and paid over for
                   all periods under all applicable legal requirements,
                   and (iii) has duly collected and remitted any sales,
                   value-added and similar Taxes required to be collected
                   and remitted.

                   (i)  There are no pending, proposed, or, to the knowledge
                   of Management Sellers, threatened, audits, judicial
                   proceedings, assessments or deficiencies with respect
                   to Taxes of the Company.  There is no pending,
                   proposed, or, to the knowledge of Management Sellers,
                   threatened, claim by any Governmental Body in any
                   jurisdiction in which any of the Sellers or the
                   Company does not pay Taxes or file Tax Returns that
                   any such Seller or the Company is required to pay
                   Taxes or file Tax Returns. 

                   (j)  The Company has not and is not required to make any
                   adjustment under Section 481(a) of the Code or any

              (a)  Except as set forth in Schedule 6.17(a), the Company
              (i) does not maintain or contribute to or have any
              obligation with respect to, and none of the employees of the

              or any other "employee benefit plan," as defined in
              Section 3(3) of ERISA, whether formal or informal
              (collectively, "Plans"), and (ii) is not a party to any
              contract for the employment of any employee of the Company
              or any other person who renders services to the Company. 
              None of the Plans is a "multiemployer plan," as defined in
              Section 3(37) of ERISA, (a "Multiemployer Plan") or a funded
              welfare benefit plan, as defined in Section 419 of the Code. 
              The Company does not have any agreement or commitment to
              create any additional Plan, enter into any additional
              employment agreement or to modify or change any existing
              Plan or employment agreement. 

              (b)  With respect to each Plan, the Company has heretofore
              delivered or made available to Publicker true, correct and
              complete copies of (i) all documents which comprise the most
              current version of each of such Plan, including any related
              trust agreements, insurance contracts, or other funding or
              investment agreements and any amendments thereto, and
              (ii) with respect to each Plan that is an "employee benefit
              plan," as defined in Section 3(3) of ERISA, (A) the two most
              recent Annual Reports (Form 5500 Series) and accompanying
              schedules for each Plan for which such a report is required,
              (B) the most current summary plan description (and any
              summary of material modifications), (C) the two most recent
              certified financial statements for each of the Plans for
              which such a statement is required or was prepared, (D) the
              Forms PBGC-1 filed in each of the two most recent plan years
              for each of the Plans for which such form was required to be
              filed, and (E) for each Plan intended to be "qualified"
              within the meaning of Section 401(a) of the Code, the
              current Internal Revenue Service determination letter issued
              with respect to such Plan.  Except as set forth in
              Schedule 6.17(b), none of the Plans has been or will be
              amended prior to the Closing Date. 

              (c)  The Company has performed and complied in all material
              respects with all of its obligations under and with respect
              to the Plans and each of the Plans has, at all times, in
              form, operation and administration complied in all material
              respects with its terms, and, where applicable, the
              requirements of all applicable laws.  Each Plan which is
              intended to be "qualified" within the meaning of
              Section 401(a) of the Code has been determined by the
              Internal Revenue Service to be so qualified and, to the
              knowledge of Management Sellers, nothing has occurred which
              reasonably could be expected to adversely affect such
              qualified status.

              (d)  There are no unpaid contributions due prior to the date
              hereof with respect to any Plan that are required to have
              been made under the terms of the Plan or any applicable law. 
              With respect to each plan subject to Section 412 of the Code
              maintained for employees of the Company or any of its ERISA
              Affiliates, there has occurred no failure to meet the
              minimum funding standards of Section 412 of the Code
              (whether or not waived in accordance with Section 412(d) of
              the Code) or failure to make by its due date a required
              installment under Section 412(m) of the Code.

              (e)  With respect to each "employee pension benefit plan," as
              defined in Section 3(2) of ERISA, in which the Company or
              any of its ERISA Affiliates participates or has participated
              at any time in the last five years (i) neither the Company
              nor any of its ERISA Affiliates has withdrawn from such plan
              during a plan year in which it was a "substantial employer,"
              as defined in Section 4001(a)(2) of ERISA, where such
              withdrawal could result in liability of such substantial
              employer pursuant to Section 4062(e) or 4063 of ERISA, (ii)
              neither the Company nor any of its ERISA Affiliates has
              filed a notice of intent to terminate any such plan or
              adopted any amendment to treat any such plan as terminated,
              (iii) the Pension Benefit Guaranty Corporation ("PBGC") has
              not instituted proceedings to terminate any such plan, (iv)
              no other event or condition has occurred which might
              constitute grounds under Section 4042 of ERISA for the
              termination of, or the appointment of a trustee to
              administer, any such plan, (v) no accumulated funding
              deficiency, whether or not waived, exists with respect to
              any such plan, and no condition has occurred or exists which
              by the passage of time would be expected to result in an
              accumulated funding deficiency as of the last day of the
              current plan year of any such plan, (vi) all required
              premium payments to the PBGC have been paid when due, (vii)
              no reportable event, as described in Section 4043 of ERISA,
              has occurred with respect to any such plan, other than
              reportable events for which the notice requirements have
              been waived by regulation, and (viii) no amendment with
              respect to which security is required under Section 307 of
              ERISA has been made or is reasonably expected to be made.

              (f)  With respect to each Plan that is subject to the provisions
              of Title I, Subtitle B, Part 3 of ERISA, (i) the actuarial
              present value (based on the actuarial assumptions used in
              the most recent actuarial valuation) of vested and nonvested
              "benefit liabilities," as defined in Section 4001(a)(16) of
              ERISA, (calculated on a termination basis using assumptions
              promulgated by the PBGC and taking into account all
              contingent and subsidized benefits) of each such Plan,
              determined as of the most recent valuation date for each
              such plan, did not exceed the fair market value of the
              assets of such Plan as of such date, and (ii) since the most
              recent valuation date for each such Plan, there has been no
              amendment or change to such Plan that would increase the
              amount of benefit liabilities thereunder and, to the
              knowledge of Management Sellers, there has been no event or
              occurrence that would materially increase or decrease the
              value of such assets or liabilities. 

              (g)  The Company has no obligation to provide health benefits or
              other non-pension benefits to retired or other former
              employees, except as specifically required by Section 4980B
              of the Code or Part 6 of Title I of ERISA or as set forth on
              Schedule 6.17(g). 

              (h)  Neither the Company nor any other "disqualified person" or
              "party in interest," as defined in Section 4975 of the Code
              and Section 3(14) of ERISA, respectively, has engaged in any
              "prohibited transaction," as defined in Section 4975 of the
              Code or Section 406 of ERISA, with respect to any Plan, nor
              have there been any fiduciary violations under ERISA which
              could subject the Company (or any officer, director or
              employee thereof) to any material penalty or tax under
              Section 502(i) of ERISA or Sections 4971 and 4975 of the
              Code.

              (i)  Except as set forth in Schedule 6.17(i), with respect to any
              Plan:  (i) no filing, application or other matter is pending
              with the Internal Revenue Service, the PBGC, the United
              States Department of Labor or any other Governmental Body,
              (ii) there is no action, suit or claim pending (nor, to the
              knowledge of Management Sellers, any basis for such a
              claim), other than routine claims for benefits, and
              (iii) there are no outstanding liabilities for taxes,
              penalties or fees.

              (j)  The Company has not incurred any liability or taken any
              action and none of Management Sellers has any knowledge of
              any action or event that could cause any one of them to
              incur any liability (i) under Section 412 of the Code or
              Title IV of ERISA with respect to any "single-employer plan"
              (as defined in Section 4001(a)(15) of ERISA), (ii) on
              account of a partial or complete withdrawal (as defined in
              Sections 4203 and 4205 of ERISA, respectively) with respect
              to any Multiemployer Plan, or (iii) on account of unpaid
              contributions to any Multiemployer Plan.

              (k)  Neither the execution and delivery of this Agreement by the
              Company or Sellers nor the consummation of any or all of the
              Contemplated Transactions by it will:  (i) entitle any
              current or former employee of the Company to severance pay,
              unemployment compensation or any similar payment, (ii)
              accelerate the time of payment or vesting or increase the
              amount of any compensation due to any such employee or
              former employee, or (iii) directly or indirectly result in
              any payment made or to be made to or on behalf of any person
              to constitute a "parachute payment" within the meaning of
              Section 280G of the Code.

         (r)  Insurance.  Schedule 6.18 sets forth a true, correct and complete
         list of all insurance policies of any kind or nature currently
         maintained by or on behalf of the Company and relating to its
         business and/or assets, indicating the type of coverage, name of
         insured, name of insurance carrier or underwriter, premium there-
         on, policy limits and expiration date of each policy.  Management
         Sellers have delivered or made available to Publicker true and
         complete copies of such insurance policies.  Such insurance
         policies provide, in the reasonable judgment of Management
         Sellers, adequate insurance coverage for the business and assets
         of the Company in light of present insurance market conditions. 
         All such insurance policies are in full force and effect, and the
         Company is not in default with respect to its obligations under
         any such insurance policy.  There are no retroactive or
         retrospective premium adjustments with respect to such insurance
         policies.  The Company has not had any insurance coverage canceled
         or denied by any carrier or received any written notice of
         cancellation or nonrenewal by any carrier, in either case since
         January 1, 1995.

                        the Company or limit the freedom of the Company

                        part and involves capital expenditures in excess
                        of $10,000;

                        (j)  each written warranty, guaranty, and/or other
                        similar undertaking with respect to contractual
                        performance extended by the Company other than

              (b)  Each of the Material Agreements is in full force and effect
              and constitutes a valid and binding obligation of the
              Company and, to the knowledge of Management Sellers, the
              other party thereto.  The Company is not in breach or
              default thereunder, and no event has occurred and no
              condition or state of facts exists which, with the passage
              of time or the giving of notice or both, would constitute
              such a default or breach by the Company or, to the knowledge
              of Management Sellers, by any such other party.  The Company
              has not received written notice of such a breach or default
              or event or condition.

             (t)  Compliance with Law; Licenses.

              conducted in all respects in accordance with all applicable

              any notification from any Governmental Body of any asserted
              present or past failure by it to comply with any such laws,
              regulations or other requirements.

              in Schedule 6.20(b) and are in full force and effect, and no
              written notice of any violation of any License has been

              any of the Facilities.
 
              (c)  Except as set forth on Schedule 6.21(c), the Company has not
              committed any material violation of any requirement of any
              Environmental Law with respect to its activities.

              (f)  Management Sellers have delivered to Publicker true and
              complete copies and results of any reports, studies,
              analyses, tests or monitoring possessed or initiated by
              Management Sellers or the Company pertaining to Hazardous
              Substances in or on the Facilities or concerning compliance
              by Management Sellers or the Company with Environmental
              Laws.

         (v)  Transactions with Related Parties.  The Company is not a party to
         any contract, lease or commitment which, were the Company a
         "Registrant" under the Securities Act, would be required to be
         disclosed pursuant to Item 404(a) or (c) of Regulation S-K as
         promulgated by the Securities and Exchange Commission, and there
         are no loans outstanding to or from any Person specified in Item
         404(a) from or to the Company. 

         (w)  Bank Accounts.  Schedule 6.23 hereto sets forth a true, correct
         and complete list of the names and addresses of all banks and
         other financial institutions in which the Company maintains an
         account, deposit or safe-deposit box, together with the names of
         all persons authorized to draw on these accounts or deposits or to
         have access to these boxes.

         (x)  No Brokers or Finders.  Sellers and the Company have not, and
         their respective officers, directors or employees have not,
         employed any broker or finder or incurred any liability for any
         brokerage or finder's fee or commissions or similar payment in
         connection with any of the Contemplated Transactions.

         (y)  Year 2000 Compliance.  The Company's Information Technology (as
         defined below) is designed to be used prior to, during, and after
         the calendar year 2000, and such Information Technology used
         during each such time period will accurately receive, provide and
         process date/time data (including calculating, comparing and
         sequencing) from, into and between the 20th and 21st centuries,
         including the years 1999 and 2000, and leap year calculations, and
         will not malfunction, cease to function, or provide invalid or
         incorrect results as a result of date/time data, to the extent
         that other Information Technology, used in combination with the
         Company's Information Technology, properly exchanges date/time
         data with it.  For purposes of this Section 6.25, "Information
         Technology" shall mean computer software, computer firmware,
         computer hardware (whether general or specific purpose), and other
         similar or related items of automated, computerized, and/or
         software systems.

         (z)  Absence of Undisclosed Liabilities.  Except as set forth on
         Schedule 6.26, the Company does not have any liabilities or
         obligations (whether known or unknown, absolute, accrued,
         contingent or otherwise and whether due or to become due) other
         than those liabilities and obligations (a) set forth or adequately
         provided for in the audited balance sheet included in the
         Financial Statements, (b) not required to be set forth in such
         balance sheet under GAAP or (c) incurred since the date of such
         balance sheet in the ordinary course of business consistent with
         past practice.

         (aa) No Material Adverse Change.  Since the date of the audited balance
         sheet included in the Financial Statements, there has not been any
         Material Adverse Effect and no event has occurred and no condition
         exists which could reasonably be expected to result in a Material
         Adverse Effect.

         (bb) Disclosure.  No representation or warranty of the Company or
         Management Sellers in this Agreement omits to state a material
         fact necessary to make the statements herein, in light of the
         circumstances in which they were made, not misleading.

         (cc) Knowledge Defined.  As used in this Section 6, "knowledge of
         Management Sellers" means the actual knowledge of Management
         Sellers and "knowledge of the Company" means the actual knowledge
         of Marc Postlewaite, Kim Vogel and Ron Smith, Esq., intellectual
         property counsel to the Company.

    (i) REPRESENTATIONS AND WARRANTIES OF SELLERS.

         Each Seller hereby severally and not jointly represents and
warrants, with respect to only such Seller, to Publicker and Acquisition Sub
as follows:

         (a)  Organization and Good Standing.  With respect to a Seller that is
         a corporation, such Seller is a corporation duly organized,
         validly existing and in good standing under the laws of the State
         of its incorporation.  With respect to a Seller that is a
         partnership, such Seller is a partnership duly formed, validly
         existing and in good standing under the laws of the State of its
         formation.  Each Seller (other than a natural person) has
         delivered to Publicker true and complete copies of its certificate
         or articles of incorporation, by-laws, certificate of partnership,
         partnership agreement, declaration of trust or other
         organizational documents.

         (b)  Authority.  Each Seller (other than a natural person) has full
         corporate, partnership or trust (as the case may be) authority to
         execute, deliver and perform this Agreement and each other
         agreement, document or instrument required to be delivered by it
         hereby or in connection herewith (collectively, the "Seller
         Documents") and to consummate the Contemplated Transactions.  Each
         Seller (including a trustee of a trust that is a Seller) that is a
         natural person has the right, capacity and all requisite authority
         to execute, deliver and perform the Seller Documents and to
         consummate the Contemplated Transactions.  The execution, delivery
         and performance by each Seller (other than a natural person or a
         trust) of the Seller Documents and the consummation of the
         Contemplated Transactions has been duly authorized by all
         necessary corporate or partnership (as the case may be) action of
         such Seller.  This Agreement has been, and each other Seller
         Document when executed and delivered in accordance with this
         Agreement will be, duly executed and delivered by each Seller. 
         This Agreement constitutes, and each of the other Seller Documents
         when executed and delivered in accordance with this Agreement will
         constitute, a valid and binding obligation of each Seller,
         enforceable against such Seller in accordance with its terms.

         (c)  Absence of Conflict.  Neither the execution, delivery or
         performance of the Seller Documents nor the consummation of the
         Contemplated Transactions will (a) violate any provision of the
         certificate or articles of incorporation, bylaws, certificate of
         partnership, partnership agreement, declaration of trust or other
         organizational document of each Seller (other than a natural
         person) or (b) violate any statute or law or any judgment, decree,
         order, regulation or rule of any court or other Governmental Body
         applicable to each Seller.

         (d)  Title to Company Shares.  All of the Company Shares beneficially
         owned by each Seller are set forth opposite such Seller's name on
         Schedule 6.2(a).  Each Seller has good and valid title to the
         Company Shares set forth opposite its name on Schedule 6.2(a) and
         owns beneficially and of record such Company Shares free and clear
         of all Encumbrances.

         (e)  Investment Representations.

              (a)  Each Seller who is identified on Schedule 7.5 as an
              "Accredited Investor" is an "Accredited Investor" within the
              meaning of Rule 501 under the Securities Act, and each
              Seller who is identified on Schedule 7.5 as not being an
              "Accredited Investor" has, alone or with its "Purchaser
              Representative(s)" (within the meaning of Rule 501 under the
              Securities Act) identified on Schedule 7.5, such knowledge
              and experience in financial and business matters that such
              Seller is capable of evaluating the merits and risks of an
              investment in the Merger Consideration.

              (b)  The Merger Consideration to be received by each Seller
              pursuant to this Agreement will be held by such Seller for
              its own account for the purpose of investment and not with a
              present view to or for sale in connection with any
              distribution thereof.

              (c)  The information furnished by each Seller in the investor
              questionnaire delivered to Publicker prior to the date of
              this Agreement was true and complete as of the date of such
              questionnaire and is currently true and complete.

              (d)  Each Seller's financial position is such that it can afford
              to bear the economic risk of holding the Merger
              Consideration it receives pursuant to this Agreement for an
              indefinite period of time, and each Seller can afford to
              suffer the complete loss of its investment in such Merger
              Consideration.

              (e)  Each Seller has been provided an opportunity to ask
              questions of, and has received answers thereto satisfactory
              to such Seller from, Publicker and its representatives
              regarding the business and affairs of Publicker and such
              other information as it desired in order to evaluate an
              investment in the Merger Consideration.

              (f)  Each Seller understands that the shares comprising the
              Merger Consideration to be received by it pursuant to this
              Agreement have not been registered under the Securities Act
              or applicable state securities laws in reliance upon
              specific exemptions from registration thereunder.  Each
              Seller agrees that the Merger Consideration to be received
              by it pursuant to this Agreement may not be sold, offered
              for sale, exchanged, transferred, pledged or otherwise
              disposed of except pursuant to a registration statement
              under the Securities Act or pursuant to an exemption from
              the registration requirements of the Securities Act and in
              compliance with state securities laws, and the shares
              comprising the Merger Consideration will bear a legend to
              such effect.

              (g)  For purposes of this Section 7.5, the term "Merger
              Consideration" refers only to the Merger Consideration
              consisting of Publicker Shares and includes any additional
              Publicker Shares issuable in lieu of any fractional
              Publicker Shares issuable as part of the Merger
              Consideration.

         (f)  Tax Matters.  No Seller is a foreign person subject to withholding
         under Section 1445 of the Code and the regulations promulgated
         thereunder.

    (j) REPRESENTATIONS AND WARRANTIES OF PUBLICKER.

         Publicker hereby represents and warrants to the Company and
Sellers as follows:

         (a)  Organization and Good Standing.  Each of Publicker and Acquisition
         Sub is a corporation duly organized, validly existing and in good
         standing under the laws of the state of its incorporation.  Each
         of Publicker and Acquisition Sub (a) has all requisite corporate
         power to own, operate and lease its properties and carry on its
         business as the same is now being conducted and (b) is qualified
         to do business as a foreign corporation in each jurisdiction set
         forth in Schedule 8.1.  Neither the location of its property nor
         the conduct of its business requires Publicker or Acquisition Sub
         to be qualified to do business as a foreign corporation in any
         state, other than those in which it is so qualified, where the
         failure to so qualify would have a materially adverse effect on
         the business, operations, results of operations or financial
         condition of Publicker and its Subsidiaries taken as a whole.

         (b)  Capitalization of the Company.

              40,000,000 shares of common stock, $0.10 par value per
              share, of which 13,291,597 shares are issued and outstanding
              as of September 30, 1998, (ii) 136,566 shares of preferred

              shares of Class A preferred stock, without par value, of
              which no shares are issued and outstanding as of September
              30, 1998.  The Publicker Shares comprising the Merger
              Consideration and any additional Publicker Shares issuable
              in lieu of any fractional Publicker Shares issuable pursuant
              to this Agreement have been duly authorized and, when issued
              and delivered in accordance with this Agreement, will be
              validly issued and fully paid and nonassessable and will be
              issued in conformity with applicable laws and not in
              violation of any preemptive rights of any Person.  Upon
              delivery to Sellers of the Publicker Shares comprising the
              Merger Consideration or any additional Publicker Shares
              issuable in lieu of any fractional Publicker Shares issuable
              pursuant to this Agreement in accordance with this
              Agreement, Sellers will acquire such Merger Consideration or
              such additional Publicker Shares free and clear of all
              Encumbrances.

              (b)  Except as set forth on Schedule 8.2, as of September 30,
              1998 there are no outstanding subscriptions, options,
              rights, warrants, convertible securities or other agreements
              (other than this Agreement) or calls, demands or commitments
              of any kind relating to the issuance, sale or transfer of
              any capital stock of Publicker.

         (c)  Authority Relative to Agreement; Compliance with Other
         Instruments; Absence of Conflict.  Each of Publicker and
         Acquisition Sub has all requisite corporate power and authority to
         execute, deliver and perform its obligations under this Agreement
         and each agreement, document or instrument required to be
         delivered by it hereby or in connection herewith (collectively,
         the "Publicker Documents").  The execution, delivery and
         performance by Publicker and Acquisition Sub of each of the
         Publicker Documents to which it is a party, and the consummation
         by Publicker and Acquisition Sub of the Contemplated Transactions,

         part of Publicker and Acquisition Sub and (a) do not require the
         consent, waiver, approval, permit, license or authorization of, or
         any declaration or filing with, any Person or other Governmental
         Body, (b) do not violate any statute or law or any judgment,
         decree, order, regulation or rule of any court or other
         Governmental Body applicable to Publicker or Acquisition Sub,
         (c) do not violate, conflict with or constitute a default (or an
         event which, with notice or lapse of time or both, would
         constitute a default) under, or provide the basis of termination
         of, or cause the acceleration of the performance required by, or
         result in the creation of any Encumbrance upon any of the
         properties or assets of Publicker or Acquisition Sub under, any
         material agreement, commitment or instrument to which Publicker or
         Acquisition Sub is a party or by which any of its assets or
         properties may be bound and (d) do not violate or conflict with
         any provision of the articles or certificate of incorporation or
         bylaws of Publicker or Acquisition Sub.

         (d)  Binding Agreement.  This Agreement has been, and each other
         Publicker Document (to which it is a party) when executed and
         delivered in accordance with this Agreement will be, duly executed
         and delivered by Publicker and Acquisition Sub.  This Agreement
         constitutes, and each such other Publicker Document when executed
         and delivered in accordance with this Agreement will constitute,
         legal and valid obligations of Publicker and Acquisition Sub
         enforceable against each of them in accordance with their terms.

         (e)  Litigation.  There is no legal, administrative, arbitral or other
         proceeding by or before any Governmental Body pending or, to the
         knowledge of Publicker, threatened against Publicker or
         Acquisition Sub, nor to the knowledge of Publicker is there any
         pending investigation by any Governmental Body, which would give
         any third party the right to enjoin or rescind the Contemplated
         Transactions or otherwise prevent Publicker or Acquisition Sub
         from complying with the terms and provisions of this Agreement.

         (f)  No Brokers or Finders.  Neither Publicker, Acquisition Sub nor any
         of their officers, directors or employees have employed any broker
         or finder or incurred any liability for any brokerage or finder's
         fee or commissions or similar payment in connection with any of
         the Contemplated Transactions.

         (g)  Reports.  Publicker has furnished to the Company a true and
         complete copy of each statement, report, registration statement
         (with the prospectus in the form filed pursuant to Rule 424(b) of
         the Securities Act), definitive proxy statement, and other filings
         filed with the Securities and Exchange Commission by Publicker
         since January 1, 1998, and, prior to the Closing Date, Publicker
         will have furnished the Company with true and complete copies of
         any additional statements, reports and documents filed with the
         Securities and Exchange Commission by Publicker prior to the
         Closing Date (collectively, the "Publicker SEC Documents").  All
         documents required to be filed as exhibits to the Publicker SEC
         Documents have been filed.  The Publicker SEC Documents include
         all statements, reports and documents required to be filed by
         Publicker pursuant to the Exchange Act and the Securities Act.  As
         of their respective filing dates, the Publicker SEC Documents
         complied in all material respects with the requirements of the
         Exchange Act and the Securities Act, as applicable, and none of
         the Publicker SEC Documents 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 made therein,
         in light of the circumstances in which they were made, not
         misleading, except to the extent corrected by a subsequently filed
         Publicker SEC Document.  The financial statements of Publicker and
         its Subsidiaries, including the notes thereto, included in the
         Publicker SEC Documents (the "Publicker Financial Statements"),
         complied as to form in all material respects with applicable
         accounting requirements and with the published rules and
         regulations of the Securities and Exchange Commission with respect
         thereto as of their respective dates (except as may be indicated
         in the notes thereto or, in the case of unaudited statements
         included in Quarterly Reports on Form 10-Q, as permitted by Form
         10-Q of the Securities and Exchange Commission).  The Publicker
         Financial Statements fairly present the consolidated financial
         condition, operating results and cash flows of Publicker and its
         Subsidiaries at the dates and during the periods indicated therein
         in accordance with GAAP (subject, in the case of unaudited
         statements, to normal recurring year-end adjustments and the
         absence of notes.

         (h)  Disclosure.  No representation or warranty of Publicker in this
         Agreement omits to state a material fact necessary to make the
         statements herein, in light of the circumstances in which they
         were made, not misleading.

         (i)  Knowledge Defined.  As used in this Section 8, "knowledge" of
         Publicker means the actual knowledge of James Weis and Antonio
         DeLise.

    (k) FURTHER AGREEMENTS OF THE PARTIES.

         (a)  Expenses.  Publicker, the Company and Sellers shall bear their own
         respective expenses incurred in connection with all obligations
         required to be performed by each of them under this Agreement;
         provided, however, the Surviving Corporation shall bear the
         reasonable fees and disbursements of counsel to the Company and
         Sellers which shall not exceed in the aggregate more than $31,575
         (unless a higher amount is approved by Publicker).

         (b)  Access Prior to the Closing.

              (a)  Between the date of this Agreement and the Closing Date,
              Management Sellers shall, and shall cause the Company to,
              (i) give Publicker and its authorized representatives full
              and complete access to all properties, personnel, facilities
              and offices of the Company and to the books and records of
              the Company (and permit Publicker to make copies thereof),
              (ii) permit Publicker to make inspections thereof, (iii)
              cause its officers and employees to furnish Publicker with
              such financial information and operating data and other

              the Company other than proprietary formulations and
              processes, and to discuss with Publicker and its authorized
              representatives the affairs of the Company, all as Publicker
              may from time to time reasonably request for the purposes of
              this Agreement during normal business hours and with
              reasonable notice to Management Sellers and the Company.

              (b)  Between the date of this Agreement and the Closing Date,
              Publicker shall hold and shall cause its officers,
              directors, employees, representatives, consultants and
              advisors to hold in strict confidence, unless compelled to
              disclose by judicial or administrative process or, in the
              opinion of its counsel, by other requirements of law, all
              documents and information furnished to Publicker by Sellers
              or the Company or their respective representatives in
              connection with the Contemplated Transactions and will not
              release or disclose such information to any other person,
              except its auditors, attorneys, financial advisors and other
              consultants, agents and advisors in connection with the
              consummation of the Contemplated Transactions.  If the
              Closing does not occur (i) such confidence shall be
              maintained by Publicker, and Publicker shall cause such
              other persons to maintain such confidence, except to the
              extent such information comes into the public domain through
              no fault of Publicker or any Person to whom Publicker
              released or disclosed such information and (ii) upon the
              request of Sellers, Publicker shall promptly return to
              Sellers any written materials it has received from Sellers,
              the Company or their respective representatives, together
              with all copies thereof.

         (c)  Public Disclosure or Communications.  Between the date of this
         Agreement and the Closing Date, except to the extent required by
         law, (a) neither Publicker, on the one hand, nor Sellers or the
         Company, on the other hand, shall issue any press release or
         public announcement of any kind concerning the Contemplated
         Transactions without the consent of the other, and in the event
         any such public announcement, release or disclosure is required by
         law, the parties will consult prior to the making thereof and use
         their best efforts to agree upon a mutually satisfactory text; (b)
         Publicker shall not, and shall not permit its representatives,
         consultants and agents to, communicate with customers, suppliers
         or employees of the Company with respect to the Contemplated
         Transactions or the business of the Company without the prior
         written consent of Management Sellers; and (c) Publicker shall not
         communicate with any government official with respect to the
         Company or Sellers or the Contemplated Transactions without the
         prior consent of Management Sellers.

         (d)  Conduct of Business of the Company.  Except as contemplated by
         this Agreement, between the date of this Agreement and the Closing
         Date, the Company shall conduct its business in the ordinary
         course and use its reasonable efforts to preserve substantially
         intact its business organization, keep available the services of
         its present officers and employees and preserve in all material
         respects its present business relationships and goodwill.  In
         addition, except as otherwise expressly provided in this
         Agreement, between the date of this Agreement and the Closing
         Date, the Company shall not:

                   (a)  amend its articles or certificate of incorporation or
                   by-laws;

                   (b)  issue, sell or otherwise dispose of any of its capital
                   stock, or create or suffer to be created any Encum-

                   change any of its capital stock, or grant or enter
                   into any options, covenants or calls or other rights
                   to purchase or convert any obligation into any of its
                   capital stock;

                   (c)  organize any Subsidiary or acquire any capital stock

                   contingent), other than in the ordinary course of
                   business; provided, however, that the Company may,
                   prior to the Closing Date, apply all or any portion of
                   its cash and cash equivalents to pay down any

                   (i)  cancel any debts or affirmatively waive any claims or
                   rights of substantial value, except for cancellations
                   made or waivers granted in the ordinary course of
                   business, which, in the aggregate, are not material;

                   as presently conducted. 

         (e)  No Negotiation.  Until the Closing or such earlier time, if any,
         as this Agreement is terminated pursuant to Section 13, Sellers
         will not, and will cause the Company not to, directly or
         indirectly solicit, initiate, or encourage any inquiries or
         proposals from, discuss or negotiate with, provide any non-public
         information to, or consider the merits of any unsolicited
         inquiries or proposals from, any Person (other than Publicker)
         relating to any transaction involving the sale of the business or
         assets (other than in the ordinary course of business) of the
         Company, or any of the capital stock of the Company, or any
         merger, consolidation, business combination, or similar
         transaction involving the Company.

         (f)  Regulatory Matters. In addition to filings required by the HSR

         any related proceedings) in order to consummate the Contemplated
         Transactions and (b) co-operate with the other as may reasonably
         be requested in connection with the foregoing.

         Shares set forth opposite his name issued pursuant to Section 5.6
         as a result of termination of such individual's employment with
         the Surviving Corporation prior to the date such options become
         exercisable, within five Business Days after the date of such
         forfeiture Publicker shall grant to (a) Marc Postlewaite an option
         to purchase 65.76% of the Publicker Shares issuable upon exercise

         requirements for use of such registration form.

         and the Closing Date, the Company shall cooperate with and assist

         that Publicker believes are necessary in order for the
         Contemplated Transactions to comply with applicable securities
         laws, including without limitation cooperation with respect to an
         audit of the financial statements of the Company.

         (o)  Financial Statements.  Prior to the Closing Date, the Company

         to this Agreement (the "Revised Schedules") solely to correct any
         inadvertent errors made on the Schedules delivered on the date of
         this Agreement.  The Revised Schedules shall be deemed to replace
         the Schedules to this Agreement delivered on the date of this
         Agreement only if (a) the Revised Schedules are in form and
         substance satisfactory to Publicker, in Publicker's good faith
         judgment, and (b) Publicker and the Company agree in writing to
         the Revised Schedules.  In the event that the Revised Schedules
         are not satisfactory to Publicker in its good faith judgment,
         Publicker may terminate this Agreement in accordance with Section
         13.

    (l) TRANSFER RESTRICTIONS.

             (a)  Transfer Restrictions on Publicker Shares.

              (a)  Transfer Restrictions.  The Publicker Shares to be received
              by Sellers pursuant to this Agreement (such shares
              collectively, the "Restricted Publicker Securities") shall
              be transferable only if sold pursuant to a registration
              statement under the Securities Act and any applicable state
              securities or blue sky laws, or pursuant to an exemption
              from the registration requirements of the Securities Act and
              applicable state securities or blue sky laws.

              (b)  Legend.  Each certificate representing the Restricted
              Publicker Securities shall bear a legend in substantially
              the following form:

              "The securities represented by this
              certificate have not been registered under
              the Securities Act of 1933, as amended, or
              under the securities or blue sky laws of
              any state, and may not be sold, or
              otherwise transferred, in the absence of
              such registration or an exemption
              therefrom under such Act and under any
              such applicable state laws."

Each certificate representing such Restricted Publicker Securities shall bear
this restrictive legend unless the restrictions on transfer provided for in
this Section 10.1 shall have ceased and terminated as to such Restricted
Publicker Securities.

              (c)  Termination of Restrictions.  The restrictions imposed by
              this Section 10.1 upon the transferability of the Restricted
              Publicker Securities shall cease and terminate as to any
              particular Restricted Publicker Securities and any
              securities issued in exchange therefor or upon transfer
              thereof when, in the opinion of counsel reasonably
              acceptable to Publicker, such restrictions are no longer
              required in order to assure compliance with the Securities
              Act, or when such Restricted Publicker Securities have been
              registered under the Securities Act.  Whenever any of such
              restrictions shall cease and terminate as to any Restricted
              Publicker Securities, the holder thereof shall be entitled
              to receive from Publicker, without expense, new certificates
              not bearing the legend set forth in Section 10.1(b).

             (b)  Lock-Up on Publicker Shares.

              (a)  Lock-Up.  During the period commencing on the Effective Date
              and ending on the first anniversary of the Closing Date (the
              "Lock-Up Period"), each Employee Seller shall not, directly
              or indirectly, sell, exchange, assign, transfer, pledge,
              encumber or otherwise dispose of any Publicker Shares it
              receives pursuant to this Agreement.

              (b)  Volume Limitations.  After the Lock-Up Period until the
              second anniversary of the Closing Date, each Employee Seller
              may sell, exchange, assign, transfer, pledge, encumber or
              otherwise dispose of, from time to time, Publicker Shares it
              receives pursuant to this Agreement only in an amount no
              greater than the amount permitted under Rule 144(e)(1)
              promulgated under the Securities Act (whether or not the
              transfer is made pursuant to Rule 144, Rule 144(e)(1)
              applies to the Employee Seller making the transfer or the
              Employee Seller is an "affiliate" of Publicker within the
              meaning of Rule 144).

              (c)  Stop Transfer Orders.  Each Employee Seller authorizes
              Publicker to cause the transfer agent for Publicker Shares
              to decline to transfer and/or to note stop transfer
              restrictions on the transfer books and records of Publicker
              with respect to any Publicker Shares for which such Employee
              Seller is the record holder.

              (d)  Legend.  Each certificate representing the Publicker Shares
              received by Employee Sellers pursuant to this Agreement
              shall, in addition to the legend described in Section
              10.1(b), bear a legend in substantially the following form:

              "The securities represented by this
              certificate are subject to certain
              transfer restrictions contained in an
              Agreement and Plan of Merger, dated
              October 30, 1998 (the "Merger Agreement"),
              among the holder of the securities
              represented by this certificate, Tritheim
              Technologies, Inc., certain other
              security-holders thereof, Publicker
              Industries Inc. ("Publicker") and
              Publicker Smart Card Acquisition Co.  A
              copy of the Merger Agreement is on file at
              the principal office of Publicker. 
              Neither this certificate nor the
              securities evidenced by this certificate
              nor any portion thereof or interest herein
              may be sold, exchanged, assigned,
              transferred, pledged, encumbered or
              otherwise disposed of in violation of the
              Merger Agreement, and any such purported
              transfer shall be null, void and of no
              effect."

Each certificate representing the Publicker Shares received by Employee
Sellers pursuant to this Agreement shall bear this restrictive legend unless
the restrictions on transfer provided for in this Section 10.2 shall have
ceased and terminated as to such Publicker Shares.  Whenever any of such
restrictions shall cease and terminate as to any such Publicker Shares, the
holder thereof shall be entitled to receive from Publicker, without expense,
new certificates not bearing the legend set forth in Section 10.2(d).

    (m) REGISTRATION RIGHTS.

             (a)  Intentionally omitted.

             (b)  Incidental Registration.

              (a)  If at any time after the Closing Date Publicker proposes to
              register any equity securities under the Securities Act for
              sale to the public (other than pursuant to a registration
              statement on Form S-4 or Form S-8 (or any successor forms)
              or any other forms not available for registering Registrable
              Publicker Shares for sale to the public), either for
              Publicker's account or for the account of others, Publicker
              shall, not less than 30 nor more than 90 days prior to the
              proposed date of filing of a registration statement under
              the Securities Act, give written notice to all Holders of
              its intention to do so.  Upon the written request of any
              Holder given within 20 days after transmittal by Publicker
              of such notice, Publicker will use its best efforts to cause
              the Registrable Publicker Shares requested to be registered
              to be so registered under the Securities Act.  A request
              pursuant to this Section 11.2(a) shall state the number of
              Registrable Publicker Shares requested to be registered and
              the intended method of disposition thereof.  The rights
              granted in this Section 11.2(a) shall apply in each case
              where Publicker proposes to register equity securities
              regardless of whether such rights may have been exercised
              previously.

              (b)  Nothing in this Agreement shall be deemed to require
              Publicker to proceed with any registration of its securities
              pursuant to Section 11.2 after giving the notice provided in
              Section 11.2(a).

         11.2A   Shelf Registration.  After the Closing Date, Publicker shall
use its reasonable efforts to cause its outstanding Publicker Shares to be
listed on a national securities exchange or to be included in an automated
quotation system of a national securities association, subject to applicable
listing or entry requirements, to enable Publicker to be eligible to use a
registration statement on Form S-3 (or any successor form) for the purpose of
registering resales of Registrable Publicker Shares.  Within a reasonable time
after becoming eligible to use a registration statement on Form S-3 (or any
successor form) for the purpose of registering resales of Registrable
Publicker Shares, Publicker shall give Holders notice of such eligibility and
shall prepare and file with the Securities and Exchange Commission a
registration statement on such form for the offering on a continuous or
delayed basis in the future of up to 100% of the Registrable Publicker Shares
outstanding as of the date prior to the date of filing with the Securities and
Exchange Commission (the "Shelf Registration Statement") and shall use its
best efforts to have the Registration Statement declared effective as promptly
as practicable.  The Shelf Registration Statement and any form of prospectus
included therein or prospectus supplement relating thereto shall reflect such
plan of distribution or method of sale as Holders may from time to time notify
Publicker.  Publicker shall use its best efforts to keep the Shelf
Registration Statement continuously effective for the period beginning on the
date on which the Shelf Registration Statement is declared effective and
ending on the first to occur of (a) the first date that all such Registrable
Publicker Shares have been sold (whether pursuant to the Shelf Registration
Statement, under Rule 144 promulgated under the Securities Act or otherwise)
or (b) the delivery to Publicker of a written opinion from counsel to
Publicker reasonably acceptable to Publicker and the Holders to the effect
that the Registrable Publicker Shares covered by the Shelf Registration
Statement may be sold without registration under the Securities Act or
applicable state law and without restriction as to the volume and timing of
such sales.  During the period during which the Shelf Registration Statement
must be kept effective, Publicker shall supplement or make amendments to the
Shelf Registration Statement, if required by the Securities Act, or if
reasonably requested by a Holder or an underwriter of Registrable Publicker
Shares, to reflect any specific plan of distribution or method of sale, and
shall use its best efforts to have such supplements and amendments declared
effective, if required, as soon as practicable after filing thereof with the
Securities and Exchange Commission.

             (c)  Limitation on Registration Requirement.

              (a)  Publicker shall have the right to postpone for up to 75 days
              any registration required pursuant to Section 11.2A if
              Publicker determines in good faith (and so certifies to
              Holders) that the filing of such registration statement
              would require the disclosure of non-public material
              information the disclosure of which would have a material
              adverse effect on Publicker or would otherwise adversely
              affect any proposal or plan by Publicker to engage in any
              acquisition of assets (other than in the ordinary course of
              business) or any merger, consolidation, tender offer or
              similar transaction.
         (d)  Registration Procedures.  If and whenever Publicker is required by
         the provisions of this Section 11 to use its best efforts to
         effect the registration of any securities under the Securities
         Act, Publicker will within the time periods provided herein:

                   (a)  prepare and file with the Securities and Exchange
                   Commission a registration statement with respect to
                   such securities and use its best efforts to cause such
                   registration statement to become and remain effective
                   for a period of time required for the disposition of
                   such securities by the holders thereof;

                   (b)  prepare and file with the Securities and Exchange
                   Commission such amendments and supplements to such
                   registration statement and the prospectus used in
                   connection therewith as may be necessary to keep such
                   registration statement effective and to comply with
                   the provisions of the Securities Act with respect to
                   the sale or other disposition of all securities
                   covered by such registration statement until the
                   earlier of such time as all of such securities have
                   been disposed of and the date which is 90 days after
                   the date of initial effectiveness of such registration
                   statement (or, with respect to the Shelf Registration
                   Statement, until such time as specified in
                   Section 11.2A);

                   (c)  furnish to each seller and to each duly authorized
                   underwriter of each seller such number of authorized
                   copies of a prospectus, including copies of a
                   preliminary prospectus, in conformity with the
                   requirements of the Securities Act, and such other
                   documents as such seller or underwriter may reasonably
                   request in order to facilitate the public sale or
                   other disposition of the securities owned by such
                   seller;

                   (d)  use its best efforts to register or qualify the
                   securities covered by such registration statement
                   under such securities or blue sky laws of such
                   jurisdictions as each seller shall request, and do any
                   and all other acts and things which may be necessary
                   under such securities or blue sky laws to enable such
                   seller to consummate the public sale or other
                   disposition in such jurisdictions of the securities to
                   be sold by such seller, except that Publicker shall
                   not for any such purpose be required to qualify to do
                   business in any jurisdiction wherein it is not
                   qualified or to file any general consent to service of
                   process in any such jurisdiction; 

                   (e)  with respect to any underwritten offering, use
                   reasonable efforts to furnish, at the request of any
                   seller, to the underwriters, on the date that such
                   seller's securities are delivered to the underwriters
                   for sale pursuant to such registration, (i) an opinion
                   of the independent counsel representing Publicker for
                   the purposes of such registration addressed to such
                   underwriters, in such form and content as the
                   underwriters may reasonably request and are customary
                   for transactions of this type, and (ii) a letter from
                   the independent certified public accountants of
                   Publicker addressed to the underwriters stating that
                   they are independent certified public accountants
                   within the meaning of the Securities Act and that, in
                   the opinion of such accountants, the financial
                   statements and other financial data of Publicker
                   included in the registration statement or the
                   prospectus, or any amendment or supplement thereto,
                   comply as to form in all material respects with the
                   applicable accounting requirements of the Securities
                   Act and covering such other matters as are customarily
                   covered in accountant's "comfort" letters; 

                   (f)  with respect to any underwritten offering, enter into
                   an underwriting agreement in customary form for a
                   transaction of this type;

                   (g)  provide and cause to be maintained a transfer agent
                   and registrar for all Registrable Publicker Shares
                   covered by such registration statement from and after
                   a date not later than the effective date of such
                   registration statement;

                   (h)  notify the Holders of Registrable Publicker Shares
                   included in such registration statement, at any time
                   when a prospectus relating thereto covered by such
                   registration statement is required to be delivered
                   under the Securities Act, of the happening of any
                   event as a result of which the prospectus included in
                   such registration statement, as then in effect,
                   includes an untrue statement of a material fact or
                   omits to state a material fact required to be stated
                   therein or necessary to make the statements therein
                   not misleading in the light of the circumstances then
                   existing and, at the request of such Holders, properly
                   prepare and furnish to such Holders a reasonable
                   number of copies of a supplement to or an amendment of
                   such prospectus as may be necessary so that, as
                   thereafter delivered to purchasers of such securities,
                   such prospectus shall not include an untrue statement
                   of a material fact or omit to state a material fact
                   required to be stated therein or necessary to make the
                   statements therein not misleading in light of the
                   circumstances under which they were made;

                   (i)  use its best efforts to list all Registrable Publicker
                   Shares covered by such registration statement on any
                   securities exchange on which the Publicker Shares are
                   then listed; and

                   (j)  otherwise use its best efforts to comply with all
                   applicable rules and regulations of the Securities and
                   Exchange Commission, and make available to its
                   security holders, as soon as reasonably practicable,

                   of the registration statement, an earnings statement
                   covering the period of at least 12 months beginning
                   with the first full calendar month after the effective
                   date of such registration statement, which earnings
                   statement shall satisfy the provisions of
                   Section 11(a) of the Securities Act.

         (e)  Expenses.  All expenses incurred in effecting the registrations
         provided for in this Section 11 (excluding underwriters' discounts
         and commissions, which shall be borne pro rata by those Holders
         for whom Registrable Publicker Shares are being registered and -
         fees of counsel to Holders which shall be borne by such Holders),
         including without limitation all registration and filing fees
         (including all expenses incident to filing with the Nasdaq Stock
         Market or any securities exchange), printing expenses, fees and
         disbursements of counsel for Publicker, fees of Publicker's
         independent auditors and accountants, expenses of any audits
         incident to or required by any such registration and expenses of
         complying with the securities or blue sky laws of any
         jurisdictions pursuant to Section 11.4(d), shall be paid by
         Publicker.

             (f)  Marketing Restrictions.

              (a)  If (i) any Holder(s) wish(es) to register any Registrable
              Publicker Shares in a registration made pursuant to
              Section 11.2A, (ii) the offering proposed to be made by such
              Holder or Holders is to be an underwritten public offering,
              (iii) Publicker or one or more holders of securities other
              than Registrable Publicker Shares to whom Publicker has
              granted registration rights wish to register securities in
              such registration and (iv) the managing underwriters of such
              public offering furnish a written opinion that the total
              amount of securities to be included in such offering would
              exceed the maximum amount of securities (as specified in
              such opinion) which can be marketed in such offering at a
              price which such Holders are prepared to sell and without
              materially and adversely affecting such offering, then the
              rights of Holders, Publicker and the holders of other
              securities with registration rights to participate in such
              offering shall be in the following order of priority:

                  First:  The Holders having the right to include such
    securities in such registration shall be entitled to participate in
    proportion to the number of Registrable Publicker Shares requested to be
    registered by each such Holder; and then

                  Second:  Publicker and all holders of securities other than
    Registrable Publicker Shares having the right to include such securities
    in such registration shall be entitled to participate pro rata among
    themselves in accordance with the number of securities requested to be
    registered by Publicker and each such holder.

              (b)  If (i) any Holder requests registration of Registrable
              Publicker Shares under Section 11.2, (ii) the offering
              proposed to be made is to be an underwritten public offering
              and (iii) the managing underwriters of such public offering
              furnish a written opinion that the total amount of
              securities to be included in such offering would exceed the
              maximum amount of securities (as specified in such opinion)
              which can be marketed at a price reasonably related to the
              then current market value of such securities and without
              materially and adversely affecting such offering, then the
              rights of Publicker, Holders and holders of other securities
              having the right to include such securities in such
              registration to participate in such offering shall be in the
              following order of priority:

                  First:  Publicker and all holders of securities other than
    Registrable Publicker Shares having the right to request such
    registration pursuant to a demand right (or otherwise initiate such
    registration) shall be entitled to participate in accordance with the
    number of securities requested to be registered by Publicker and each
    such holder and in accordance with the registration rights of each such
    holder; and then

                  Second: All other holders of securities, including Holders
    of Registrable Publicker Shares, having the right to include such
    securities in such registration shall be entitled to participate pro
    rata among themselves in accordance with the number of securities
    requested to be registered by each such holder;

and no securities (issued or unissued) other than those registered and
included in the underwritten offering shall be offered for sale or other
disposition by Holders in a transaction which would require registration under
the Securities Act until the expiration of 180 days after the effective date
of the registration statement in which Registrable Publicker Shares were
included pursuant to Section 11.2 or such shorter period as may be acceptable
to Publicker.

         (g)  Time Limitations; Termination of Rights.  Notwithstanding anything
         contained in this Section 11, the rights to registration under
         this Section 11 shall terminate as to any particular Registrable
         Publicker Shares when (i) such Registrable Publicker Shares shall
         have been effectively registered under the Securities Act and sold
         by the holder thereof in accordance with such registration, (ii)
         such Registrable Publicker Shares shall have been sold in
         compliance with Rule 144 promulgated under the Securities Act or
         otherwise in a public transaction or (iii) written opinions from
         counsel reasonably acceptable to Publicker and the holder of such
         Registrable Publicker Shares, to the effect that such Registrable
         Publicker Shares may be sold without registration under the
         Securities Act or applicable state law and without restriction as
         to the volume and timing of such sales, shall have been received
         from either counsel to Publicker or counsel to the holders
         thereof.

         (h)  Compliance with Rule 144.  At all times during which this
         Agreement is effective, Publicker shall file with the Securities
         and Exchange Commission, in a timely manner, all reports and other
         documents required to be filed by Publicker with the Securities
         and Exchange Commission pursuant to the Exchange Act.

         (i)  Indemnification by Publicker.  In the event of any registration
         under the Securities Act of any Registrable Publicker Shares
         pursuant to this Section 11, Publicker hereby agrees to execute an
         agreement with any underwriter participating in the offering
         thereof containing such underwriter's standard representations and
         indemnification provisions and to indemnify and hold harmless each
         Holder disposing of Registrable Publicker Shares, each Person, if
         any, who controls such Holder within the meaning of the Securities
         Act and each other Person (including each underwriter and each
         Person who controls such underwriter) who participates in the
         offering of Registrable Publicker Shares, against any losses,
         claims, damages or liabilities, joint or several, to which such
         Holder, controlling Person or participating Person may become
         subject under the Securities Act or otherwise, insofar as such
         losses, claims, damages or liabilities (or proceedings in respect
         thereof) arise out of or are based upon any untrue statement or
         alleged untrue statement of any material fact contained in any
         registration statement under which the Registrable Publicker
         Shares are registered under the Securities Act, in any preliminary
         prospectus or final prospectus contained therein, or in any
         amendment or supplement thereto, or arise out of or are based upon
         the omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, and will reimburse each such Holder,
         controlling Person and participating Person for any legal or other
         expenses reasonably incurred in connection with investigating or
         defending any such loss, claim, damage, liability or proceeding;
         provided, however, that Publicker will not be liable in any case
         to any such Holder, controlling Person or participating Person to
         the extent that any loss, claim, damage or liability results from
         any untrue statement or alleged untrue statement or omission or
         alleged omission made in such registration statement, preliminary
         or final prospectus or amendment or supplement in reliance upon
         and in conformity with information furnished to Publicker by any
         Holder or any other Person who participates as an underwriter in
         the offering or sale of such securities, specifically for use in
         the preparation thereof; provided, further, however, that the
         indemnity set forth in this Section 11.9 shall not inure to the
         benefit of any such Holder, controlling Person or participating
         Person on account of any loss, claim, damage or liability arising
         from the sale of Registrable Publicker Shares to any Person by a
         Holder or participating Person if any Holder or participating
         Person failed to deliver a copy of such preliminary prospectus or
         final prospectus (as then amended or supplemented) to that person
         within the time required by applicable securities laws and the
         untrue statement or alleged untrue statement of any material fact
         or omission or alleged omission to state a material fact in a
         prospectus was corrected in the preliminary or final prospectus or
         amended or supplemented prospectus which the Holder or
         participating Person failed to deliver, unless such failure of
         delivery resulted from Publicker's failure to deliver to the
         Holders and participating Persons such corrected prospectus in the
         requisite quantity and on a timely basis to permit proper delivery
         thereof.  Such indemnity shall remain in full force and effect
         regardless of any investigation made by or on behalf of any Holder
         disposing of Registrable Publicker Shares or any such underwriter
         or controlling Person and shall survive the transfer of such
         securities by such Holder and the expiration or termination of the
         registration rights granted under this Section 11 pursuant to
         Section 11.7.

         (j)  Indemnification by Holder.

              (a)  As a condition of Publicker's obligation under this
              Section 11 to effect any registration under the Securities
              Act, there shall be delivered to Publicker an agreement or
              agreements duly executed by each Holder for whom Registrable
              Publicker Shares are to be so registered, whereby such
              Holder agrees to indemnify and hold harmless (in the same
              manner as set forth in Section 11.9 above) Publicker, each
              person referred to in clause (1), (2) or (3) of
              Section 11(a) of the Securities Act in respect of the
              registration statement and each other person, if any, who
              controls Publicker within the meaning of the Securities Act,
              with respect to any untrue statement or alleged untrue
              statement of any material fact contained in the registration
              statement under which the Registrable Publicker Shares are
              to be registered under the Securities Act, in any
              preliminary prospectus or final prospectus contained therein
              or in any amendment or supplement thereto, or arise out of
              or are based upon the omission or alleged omission to state
              therein a material fact required to be stated therein or
              necessary to make the statements therein not misleading,
              which, in each case, is made in or omitted from the
              registration statement, preliminary or final prospectus or
              amendment or supplement in reliance upon and in conformity
              with information furnished to Publicker by such Holder
              specifically for use in the preparation thereof.  Such
              indemnity shall remain in full force and effect regardless
              of any investigation made by or on behalf of Publicker or
              any person indemnified by virtue of this Section 11.10 and
              shall survive the transfer of such securities by such Holder
              and the expiration or termination of the registration rights
              granted under this Section 11 pursuant to Section 11.7.

              (b)  At the request of the managing underwriter in connection
              with any underwritten offering of Publicker's securities,
              each Holder for whom Registrable Publicker Shares are being
              registered shall enter into an indemnity agreement in
              customary form with such underwriter.

         (k)  Contribution.  If the indemnification provided for in Section 11.9
         or 11.10 from the indemnifying party is unavailable to an
         indemnified party hereunder, or is insufficient to hold harmless
         an indemnified party, in respect of any losses, claims, damages,
         liabilities or expenses referred to therein, then the indemnifying
         party, in lieu of indemnifying such indemnified party, shall
         contribute to the amount paid or payable by such indemnified party
         as a result of such losses, claims, damages, liabilities or
         expenses in such proportion as is appropriate to reflect the
         relative fault of the indemnifying party and indemnified parties
         in connection with the actions which resulted in such losses,
         claims, damages, liabilities or expenses, as well as any other
         relevant equitable considerations.  The relative fault of such
         indemnifying party and indemnified parties shall be determined by
         reference to, among other things, whether any action in question,
         including any untrue or alleged untrue statement of a material
         fact or omission or alleged omission to state a material fact, has
         been made by, or relates to information supplied by, such
         indemnifying party or indemnified parties, and the parties'
         relative intent, knowledge, access to information and opportunity
         to correct or prevent such untrue statement or omission.  The
         amount paid or payable by an indemnified party as a result of the
         losses, claims, damages, liabilities and expenses referred to
         above shall be deemed to include any legal or other fees or
         expenses reasonably incurred by such party in connection with any
         investigation or proceeding.

         The parties hereto agree that it would not be just and equitable
if contribution pursuant to this Section 11.11 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph.  No Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any indemnifying party who was not guilty of such fraudulent
misrepresentation.

         (l)  Notification of and Participation in Actions.  The procedures
         described in Sections 12.3 and 12.4 shall apply to any claim
         covered by this Section 11.  All indemnification obligations of
         the parties hereto shall survive any termination of the
         registration rights granted under this Section 11 pursuant to Sec-
         tion 11.7.

         (m)  Underwriting Requirements.

              (a)  In the event of an underwritten offering of Publicker's
              securities, each Holder for whom Registrable Publicker
              Shares are being registered pursuant to Section 11.2 or
              Section 11.2A shall, as a condition to inclusion of such
              Registrable Publicker Shares in such registration, execute
              and deliver to the underwriter(s) an underwriting agreement
              in customary form.  The underwriter(s) shall be selected (i)
              by the Holders requesting registration of Registrable
              Publicker Shares, in the case of a registration pursuant to
              Section 11.2A (which underwriters shall be acceptable to
              Publicker) or (ii) by Publicker, in the case of a
              registration pursuant to Section 11.2.

              (b)  At the request of the managing underwriter in connection
              with any underwritten offering of Publicker's securities,
              the Holders for whom Registrable Publicker Shares are being
              registered shall enter into customary "lock-up" agreements.

         (n)  Furnish Information.  It shall be a condition precedent to the
         obligations of Publicker to take any action pursuant to Section 11
         that Holders requesting registration of Registrable Publicker
         Shares furnish to Publicker such information regarding them, the
         Registrable Publicker Shares held by them and the intended method
         of disposition of such securities as Publicker shall reasonably
         request and as shall be required in connection with the action to
         be taken by Publicker.

         (o)  Permitted Transfers.  The registration rights granted to Sellers
         (other than Employee Sellers) under this Section 11 may only be
         transferred to a transferee who acquires Registrable Publicker
         Shares from any Seller (other than an Employee Seller), is a
         permitted transferee under Section 10 and is either (i) the spouse
         or member of the immediate family of a Seller (other than an
         Employee Seller); (ii) a trust for the benefit of a Seller (other
         than an Employee Seller) or any member of such Seller's immediate
         family; or (iii) a corporation, partnership or other entity the
         only owners of which are one or more Sellers (other than Employee
         Sellers) and members of their immediate families; provided that
         any transferring Seller gives written notice at the time of such
         transfer to Publicker stating the name and address of the
         transferee and identifying the Registrable Publicker Shares so
         transferred, accompanied by a signature page to this Agreement
         pursuant to which such transferee agrees to be bound by the terms
         and conditions of this Section 11.


         (p)  Put Rights.

              (a)  Put Rights.  If the Shelf Registration Statement is not
              declared effective within six months after the Closing Date,
              each of the Holders listed on Schedule 11.16 (the "Put
              Holders") shall have the right to request that Publicker
              purchase all or part of the Publicker Shares held by such
              Put Holder which were received by such Put Holder as
              consideration in the Merger pursuant to this Agreement ("Put
              Shares") for a cash purchase price per Publicker Share equal
              to the Fair Market Value on the Put Date (as defined below)
              of one Publicker Share, in accordance with the terms of this
              Section 11.16.

              (b)  Exercise of Put.  To exercise its put rights under Section
              11.16(a), a Put Holder shall give notice of its put request
              (the "Put Notice") to Publicker at any time after its put
              rights become exercisable under Section 11.16(a) and prior
              to the earlier of (i) the first date upon which the Shelf
              Registration Statement is declared effective and (ii) the
              date upon which a written opinion from counsel reasonably
              acceptable to Publicker and such Put Holder, to the effect
              that such Put Holder's Put Shares may be sold without
              registration under the Securities Act or applicable state
              law and without restriction as to volume and timing of
              sales, shall have been received from either counsel to
              Publicker or counsel to such Put Holder.  The closing of
              Publicker's purchase of the Put Shares shall occur at such
              place, date and time as is determined by Publicker, provided
              that the place, date and time shall be no earlier than three
              Busines Days after the Put Notice and no later than seven
              Business Days after the Put Notice.  The Put Notice shall
              specify the total number of Put Shares requested to be
              purchased by Publicker.

              (c)  Conditions to Closing of Put.  The obligation of Publicker
              to purchase any Put Shares is subject to the condition that
              no preliminary or permanent injunction or other order by a
              court of competent jurisdiction prohibiting or otherwise
              restraining such sale shall be in effect.  Each Put Holder
              and Publicker shall use its best efforts to make all filings
              and registrations with, and to obtain all consents,
              approvals, orders or authorizations of, any Governmental
              Body, if any, required in connection with the sale of such
              Put Holder's Put Shares under this Section 11.16.

              (d)  Closing of Option.  At the closing of any purchase by
              Publicker of Put Shares (such date and time referred to
              herein as the "Put Date"), (i) the selling Put Holder shall
              deliver to Publicker (A) stock certificates representing the
              Put Shares duly endorsed for transfer to Publicker, or
              accompanied by stock powers duly endorsed in blank, with all
              requisite documentary tax stamps affixed thereto and (B) a
              simple sale agreement, in form and substance satisfactory to
              Publicker, containing representations and warranties similar
              to those contained in Sections 7.1, 7.2, 7.3 and 7.4 and
              (ii) Publicker shall deliver to such Put Holder a check
              payable to the order of such Put Holder in the amount of the
              purchase price determined in accordance with Section
              11.16(a).

    (n) INDEMNIFICATION AND RELATED MATTERS; SELLERS' RELEASE; TAX MATTERS. 
                                                                             
                   

             (a)  Indemnification.

                       (a)  Indemnification by Management Sellers.

                        (a)    Each of the Management Sellers shall jointly and
                        severally indemnify and hold harmless Publicker
                        and its agents, representatives, employees,
                        officers, directors, stockholders, controlling
                        persons and Affiliates (collectively, the
                        "Publicker Indemnitees"), and shall reimburse
                        the Publicker Indemnitees, for any loss,
                        liability, claim, damage or expense (including,
                        but not limited to, costs of investigation and
                        defense and reasonable attorneys' fees), whether
                        or not involving a third-party claim
                        (collectively, "Damages"), arising from or in
                        connection with (A) any inaccuracy in any of the
                        representations and warranties of the Company or
                        any Management Seller in this Agreement (other

                        Management Seller or the Company pursuant to
                        this Agreement or referred to in this Agreement
                        or in any such other certificate or document,
                        (B) any failure of the Company or any Management
                        Seller to perform or comply with any agreement
                        to be performed or complied with by it in this
                        Agreement, (C) any claim by any Person for
                        brokerage or finder's fees or similar payments

                        Transactions as the result of brokers, finders
                        or investment bankers retained by any Seller or

                        unmatured) of Harold E. Taylor or his successors
                        or assigns relating to the issuance of any
                        capital stock of the Company, which arises from
                        or relates to the conduct of the business or the
                        operations of the Company on or prior to the
                        Closing Date or any agreements (whether or not
                        in writing) with the Company or any of its
                        officers, directors, employees or agents entered
                        into on or prior to the Closing Date or

                        indemnification provisions contained herein.

                        (b)    Each of Management Sellers shall jointly and

                        relating to any portion of the Facilities or to
                        any other property incurred by, imposed upon, or
                        commenced or asserted against any Publicker
                        Indemnitee or the Company at any time, resulting
                        in whole or in part from, or related in any way

                        case on or prior to the Closing Date.

                        (c)    Each Management Seller may satisfy its liability
                        under this Section 12.1(a) by delivering to
                        Publicker that number of Publicker Shares
                        received by such Management Seller to such
                        indemnification payment date pursuant to this
                        Agreement having an aggregate Fair Market Value
                        on the date of delivery to Publicker pursuant to
                        this Section 12.1(a)(iii) equal to such
                        Management Seller's liability.  Notwithstanding
                        the foregoing, (A) the indemnifying Management
                        Sellers shall have no liability to Publicker
                        under Section 12.1(a)(i)(A) or (B) or
                        Section 12.1(a)(ii) until the aggregate amount
                        of all Damages under such Sections exceeds
                        $25,000 and then only for all such Damages in
                        excess of such amount and (B) the maximum
                        liability of each Management Seller pursuant to
                        this Section 12.1(a) shall not exceed in the
                        aggregate the lesser of (1) all of the Publicker
                        Shares received by such Management Seller to the
                        indemnification payment date pursuant to this
                        Agreement, if such Management Seller chooses to
                        deliver such shares to Publicker pursuant to
                        this Section 12.1(a)(iii) and (2) the Fair
                        Market Value, on the date on which the shares
                        were received by such Management Seller, of the
                        Publicker Shares received by such Management
                        Seller to such indemnification payment date
                        pursuant to this Agreement.  The limitations set
                        forth in this Section 12.1(a)(iii) shall not
                        apply to any Management Seller to the extent of
                        Damages arising from fraud on the part of such
                        Management Seller.

              (b)  Indemnification by Sellers.  Each of the Sellers shall
              severally and not jointly indemnify and hold harmless
              Publicker and the other Publicker Indemnitees, and shall
              reimburse Publicker and the other Publicker Indemnitees, for
              any Damages arising from or in connection with (i) any
              inaccuracy in any of the representations and warranties of
              such Seller in Section 7 of this Agreement or in any
              certificate or other document required to be delivered by
              such Seller pursuant to this Agreement, (ii) any failure of
              such Seller to perform or comply with any agreement to be
              performed or complied with by it in this Agreement, or
              (iii) Publicker's enforcement of the indemnification
              provisions contained herein.  Each Seller may satisfy its
              liability under this Section 12.1(b) by delivering to
              Publicker that number of Publicker Shares received by such
              Seller to such indemnification payment Date pursuant to this
              Agreement having an aggregate Fair Market Value on the date
              of delivery to Publicker pursuant to this Section 12.1(b)
              equal to such Seller's liability.  Notwithstanding the
              foregoing, (A) no indemnifying Seller shall have any
              liability to Publicker under clause (i) or (ii) of this
              Section 12.1(b) until the aggregate amount of all Damages
              under such clauses exceeds $10,000 and then only for all
              such Damages in excess of such amount, and (B) the maximum
              liability of each Seller pursuant to this Section 12.1(b)
              shall not exceed in the aggregate the lesser of (1) all of
              the Publicker Shares received by such Seller to the
              indemnification payment date pursuant to this Agreement, if
              such Seller chooses to deliver such shares to Publicker
              pursuant to this Section 12.1(b) and (2) the Fair Market
              Value, on the date on which the shares were received by such
              Seller, of the Publicker Shares received by such Seller to
              such indemnification payment date pursuant to this
              Agreement.  The limitations set forth in this
              Section 12.1(b) shall not apply to any Seller to the extent
              of Damages arising from fraud on the part of such Seller.

              (c)  Indemnification by Publicker.  Publicker shall indemnify and
              hold harmless the Sellers (the "Seller Indemnitees"), and
              shall reimburse the Seller Indemnitees, for any Damages
              arising from or in connection with (i) any inaccuracy in any
              of the representations and warranties of Publicker in this
              Agreement or in any certificate or other document required
              to be delivered by Publicker pursuant to this Agreement or
              referred to in this Agreement or in any such other
              certificate or document, (ii) any failure by Publicker or
              Acquisition Sub to perform or comply with any agreement to
              be performed or complied with by it in this Agreement, (iii)
              any claim by any Person for brokerage or finder's fees or
              similar payments in connection with any of the Contemplated
              Transactions as the result of brokers, finders or investment
              bankers retained by Publicker, or (iv) the Seller
              Indemnitees' enforcement of the indemnification provisions
              contained herein.  Notwithstanding the foregoing, (A)
              Publicker shall have no liability under clause (i) or (ii)
              of this Section 12.1(c) until the aggregate amount of all
              Damages under such clauses exceeds $25,000 and then only for
              all such Damages in excess of such amount and (B) the
              maximum liability of Publicker pursuant to this
              Section 12.1(c) shall not exceed the Fair Market Value on
              the Closing Date of the aggregate Merger Consideration paid
              by Publicker pursuant to this Agreement.  The limitations
              set forth in this Section 12.1(c) shall not apply to
              Publicker to the extent of Damages arising from fraud on the
              part of Publicker.

         (b)  Survival of Representations and Warranties.  The representations
         and warranties of the Company, Management Sellers, Sellers and
         Publicker contained in this Agreement shall survive the Closing;
         provided, that a party shall have no liability (for
         indemnification or otherwise) for a breach of any representation
         or warranty or breach of covenant or obligation to be performed
         and complied with prior to the Closing Date, unless on or before
         the date that is the 18-month anniversary of the Closing Date such
         party is given notice asserting a claim with respect thereto and
         specifying the factual basis of the claim and extent of the
         Damages in reasonable detail.  Notwithstanding the foregoing, (a)
         indemnification claims under Section 12.1(a)(i) for breach of the
         representations in Sections 6.2(a), 6.2(c), 6.14, 6.17 and 6.21
         may be made by Publicker at any time, (b) indemnification claims
         under Section 12.1(b) for breach of the representations in
         Section 7.4 may be made by Publicker at any time, (c)
         indemnification claims made under Section 12.1(a)(i)(B),
         12.1(b)(ii) or 12.1(c)(ii) for covenants or obligations to be
         performed and complied with after the Closing Date may be made at
         any time, (d) indemnification claims under Sections 12.1(a)(i)(C),
         (D) and (E), 12.1(a)(ii), 12.1(b)(iii) and 12.1(c)(iii) and (iv)
         may be made at any time and (d) nothing in this Section 12.2 shall
         limit or otherwise affect the rights of either party under
         Section 11 or 12.6.

         (c)  Procedure for Indemnification -- Third Party Claims.  Promptly
         after receipt by an indemnified party under Section 12.1(a),
         12.1(b) or 12.1(c) or Section 11.9 or 11.10 of oral or written
         notice of a claim or the commencement of any proceeding against
         it, such indemnified party shall, if a claim in respect thereof is
         to be made against an indemnifying party under such Section, give
         written notice to the indemnifying party of the commencement
         thereof, but the failure so to notify the indemnifying party shall
         not relieve it of any liability that it may have to any
         indemnified party except to the extent the indemnifying party
         demonstrates that the defense of such action is prejudiced
         thereby. In case any such proceeding shall be brought against an
         indemnified party and it shall give notice to the indemnifying
         party of the commencement thereof, the indemnifying party shall be
         entitled to participate therein and, to the extent that it shall
         wish (unless the indemnifying party is also a party to such
         proceeding and the indemnified party determines in good faith that
         joint representation would be inappropriate) to assume the defense
         thereof with counsel reasonably satisfactory to such indemnified
         party and, after notice from the indemnifying party to such
         indemnified party of its election so to assume the defense
         thereof, the indemnifying party shall not be liable to such
         indemnified party under such Section for any fees of other counsel
         or any other expenses with respect to the defense of such
         proceeding, in each case, subsequently incurred by such
         indemnified party in connection with the defense thereof.  If an
         indemnifying party assumes the defense of such proceeding, (a) no
         compromise or settlement thereof may be effected by the
         indemnifying party without the indemnified party's reasonable
         consent unless (i) there is no finding or admission of any
         violation of law or any violation of the rights of any Person and
         no effect on any other claims that may be made against the
         indemnified party and (ii) the sole relief provided is monetary
         damages that are paid in full by the indemnifying party and (b)
         the indemnifying party shall have no liability with respect to any
         compromise or settlement thereof effected without its reasonable
         consent.  If notice is given to an indemnifying party of the
         commencement of any proceeding and it does not, within 15 Business
         Days after the indemnified party's notice is given, give notice to
         the indemnified party of its election to assume the defense
         thereof, the indemnifying party shall be bound by any
         determination made in such action or any compromise or settlement
         thereof effected by the indemnified party.  Notwithstanding the
         foregoing, if an indemnified party determines in good faith that
         there is a reasonable probability that a proceeding may adversely
         affect it or its Affiliates other than as a result of monetary
         damages, such indemnified party may, by notice to the indemnifying
         party, assume the exclusive right to defend, compromise or settle
         such proceeding, but the indemnifying party shall not be bound by
         any determination of a proceeding so defended or any compromise or
         settlement thereof effected without its consent (which shall not
         be unreasonably withheld). 

         (d)  Procedure for Indemnification -- Other Claims.  A claim for
         indemnification for any matter not involving a third-party claim
         may be asserted by notice to the party from whom indemnification
         is sought.

             (e)  Company's and Sellers' Releases.  If the Closing shall occur:

                   (a)  Each Seller hereby releases and forever discharges
                   Publicker, the Company and each of their respective
                   agents, representatives, employees, officers,
                   directors, stockholders, controlling persons and
                   Affiliates (individually a "Releasee" and
                   collectively, "Releasees") from any and all claims,
                   demands, Proceedings, causes of action, orders,
                   obligations, contracts, agreements, debts and
                   liabilities whatsoever, whether known or unknown,
                   suspected or unsuspected, both at law and in equity,
                   which each Seller now has, have ever had or may
                   hereafter have against the respective Releasees
                   arising contemporaneously with or prior to the Closing
                   Date or on account of or arising out of any matter,
                   cause or event occurring contemporaneously with or
                   prior to the Closing Date; provided, however, that
                   nothing contained in this Section 12.5(a) shall
                   operate to release (i) any obligation of the Company
                   disclosed in this Agreement (on a Schedule or
                   otherwise) or (ii) any obligations of Publicker or the
                   Company arising under this Agreement or under any
                   agreement contemplated by this Agreement; 

                   (b)  Each of the Company and Sellers hereby releases and
                   forever discharges any and all claims, demands,
                   Proceedings and causes of action against Publicker and
                   the other Publicker Indemnitees arising out of,
                   incidental to, or in any manner connected with
                   Contamination existing at or in the Facilities, or any
                   portion thereof or elsewhere, with any Release of a
                   Hazardous Substance at or on the Facilities or
                   elsewhere, or with any violation of an Environmental
                   Law, in each case occurring on or prior to the Closing
                   Date; and

                   (c)  each of the Company and Sellers (as the case may be)
                   hereby irrevocably covenants to refrain from, directly
                   or indirectly, asserting any claim or demand, or
                   commencing, instituting or causing to be commenced,
                   any proceeding of any kind against (i) any Releasee
                   based upon any matter purported to be released under
                   Section 13.5(a) or (ii) any Publicker Indemnitee based
                   upon any matter purported to be released under
                   Section 12.5(b).

             (f)  Tax Matters.

              (a)  Sellers shall pay all transfer, documentary, sales, use,
              registration, stamp, value-added and other similar Taxes
              (including all applicable real estate transfer taxes),
              including any penalties, interest and additions to tax,
              incurred in connection with the Contemplated Transactions
              other than the issuance of Publicker Shares hereunder, with
              respect to which Publicker shall pay such Taxes.

              (b)  Sellers shall file or cause to be filed all Tax Returns for
              the taxable periods of the Company ending on or prior to the
              Closing Date.  In the case of any taxable period of the
              Company that begins prior to and ends after the Closing
              Date, Publicker shall cause to be prepared and filed any
              required Tax Returns.  Each of Sellers and Publicker shall
              cause all Tax Returns addressed in this Section 12.6(b) to
              be prepared in accordance with the methodology used in prior
              taxable years, except as otherwise required by legal
              requirements.

              (c)  Sellers will pay, and will indemnify and hold harmless
              Publicker, its Affiliates, the Surviving Corporation and the
              Company from and against, (i) any Taxes imposed upon the
              Company or the Surviving Corporation for any taxable period
              ending on or prior to the Closing Date and (ii) Taxes
              imposed upon the Company or the Surviving Corporation in
              connection with the Contemplated Transactions.  Unless
              otherwise provided herein, the Closing Date shall be treated
              as the last day of a taxable period whether or not any
              taxable period actually ends on such date.  Sellers'
              obligations under this Section 12.6(c) shall not be limited
              in any way by Section 12.1(a), Section 12.1(b) or Section
              12.2.

              (d)  Sellers and Publicker shall each provide the other with such
              assistance as may be reasonably requested (including making
              employees reasonably available to provide information or
              testimony) in connection with the preparation of any Tax
              Return, any Seller Tax Controversies (as defined in Section
              12.6(e)), or the determination of liability for Taxes with
              respect to the Company or the Surviving Corporation.

              (e)  (i) Publicker shall, in the event that Publicker receives
              written notice of any examination, claim, proposed
              settlement, proposed adjustment or related matter with
              respect to any Taxes for which Publicker may be indemnified
              hereunder (the "Seller Tax Controversies"), promptly notify
              Sellers thereof; provided, however, that failure to give
              such notification shall not affect the indemnification
              provided hereunder except to the extent Sellers shall have
              been actually prejudiced as a result of such failure. 
              Sellers shall be entitled at their sole discretion and
              expense to handle, control and compromise or settle the
              Seller Tax Controversies, and shall reasonably inform
              Publicker of the progress of the Seller Tax Controversies;
              provided, however, that Sellers shall not settle or
              compromise any Seller Tax Controversy in a manner that would
              adversely affect any unindemnified Tax liability of
              Publicker, any of its Affiliates, the Surviving Corporation
              or the Company without the consent of Publicker, such
              consent not to be withheld unreasonably.

         (ii)  Sellers shall, in the event any Seller receives written
notice of any examination, claim, proposed settlement, proposed adjustment or
related matter with respect to Taxes attributable to the Company or the
Surviving Corporation, promptly notify Publicker thereof. 

    (o) TERMINATION.

         (a)  Termination Procedures.  This Agreement may be terminated and the
         Merger may be abandoned at any time prior to the Effective Time as
         follows:

                   (a)  by written agreement of Publicker, Acquisition Sub and
                   the Company (duly authorized by their Boards of
                   Directors) at any time;

                   (b)  by Publicker, by notice to the Company at any time, if
                   satisfaction of any of the conditions specified in
                   Section 4 becomes impossible and such condition has
                   not been waived by Publicker;

                   (c)  by the Company, by notice to Publicker at any time, if
                   satisfaction of any of the conditions specified in
                   Section 5 becomes impossible and such condition has
                   not been waived by the Company;

                   (d)  by Publicker, by notice to the Company if the
                   conditions to Publicker's and Acquisition Sub's
                   obligations set forth in Section 4 have not been
                   satisfied or waived by Publicker by December 15, 1998;
                   

                   (e)  by the Company by notice to Publicker, if the
                   conditions to the Company's obligations set forth in
                   Section 5 have not been satisfied or waived by the
                   Company by December 15, 1998; or

                   (f)  by Publicker, by notice to the Company, if any of the
                   Revised Schedules delivered to Publicker pursuant to
                   Section 9.16 are not in form and substance
                   satisfactory to Publicker, in Publicker's good faith
                   judgment.

         (b)  Effect of Termination.  In the event that this Agreement is
         terminated pursuant to Section 13.1, this Agreement shall
         terminate without any liability or further obligation of any party
         to another, except for the obligations of Publicker, the Company
         and Sellers under Section 9.1 and Publicker under Section 9.2(b),
         which obligations shall survive termination; provided, however,
         that if this Agreement is terminated by a party because of the
         breach of this Agreement by the other party or because one or more
         of the conditions to the terminating party's obligations under
         this Agreement is not satisfied as a result of the other party's
         failure to comply with its obligations under this Agreement, the
         terminating party's right to pursue all legal remedies will
         survive such termination unimpaired.

                   consents in connection with this Agreement and the
                   consummation of the Contemplated Transactions as the
                   Sellers' Agent, in his sole discretion, may deem
                   necessary or desirable; 

                   (c)  to receive any notices and other documents on behalf
                   of Sellers pursuant to this Agreement; and

                   (d)  to make, execute, acknowledge and deliver all such
                   other agreements, notices, requests, instructions,
                   certificates, stock powers, letters and other
                   writings, and, in general, to do any and all things
                   and to take any and all action that the Sellers'
                   Agent, in his sole and absolute discretion, may
                   consider necessary or proper or convenient in
                   connection with or to carry out the activities
                   described in this Section 14.1 and the Contemplated
                   Transactions.

                  The grant of authority provided for in this Section 14.1: 
    (i) is coupled with an interest and being granted, in part, as an
    inducement to Publicker and Acquisition Sub to enter into this Agreement
    and the other agreements, documents, instruments and certificates
    contemplated hereby and shall be irrevocable and survive the death,
    incompetency, bankruptcy or liquidation of any Seller and shall be
    binding on any successor thereto; and (ii) shall survive any permitted
    assignment by a Seller of the whole or any fraction of his or her
    interest hereunder.

             (b)  Compensation; Exculpation; Indemnity.

              (a)  The Sellers' Agent shall not be entitled to any fee,
              commission or other compensation for the performance of its
              services as such, but shall be entitled to receive from
              Sellers the payment of all of its expenses incurred as
              Sellers' Agent.

              (b)  In dealing with this Agreement and any instruments,
              agreements or documents relating hereto, and in exercising
              or failing to exercise all or any of the powers conferred
              upon the Sellers' Agent hereunder, (i) the Sellers' Agent
              assumes and shall incur no responsibility whatsoever to any
              Seller by reason of any error in judgment or other act or
              omission performed or omitted hereunder or in connection
              with this Agreement or any such other agreement, instrument
              or document, excepting only responsibility for any act or
              failure to act which represents gross negligence or willful
              misconduct, and (ii) the Sellers' Agent shall be entitled to
              rely on the advice of counsel, public accountants or other
              independent experts experienced in the matter at issue, and
              any error in judgment or other act or omission of the
              Sellers' Agent pursuant to such advice shall in no event
              subject the Sellers' Agent to liability to any Seller.

              (c)  Each Seller, severally, shall indemnify the Sellers' Agent
              against all damages, liabilities, claims, obligations, costs
              and expenses, including reasonable attorneys', accountants'
              and other experts' fees and the amount of any judgment
              against them, of any nature whatsoever, arising out of or in
              connection with any claim, investigation, challenge, action
              or proceeding or in connection with any appeal thereof,
              relating to the acts or omissions of the Sellers' Agent
              under this Agreement or otherwise.  The foregoing
              indemnification shall not be deemed exclusive of any other
              right to which the Sellers' Agent may be entitled apart from
              the provisions hereof.  The foregoing indemnification shall
              not apply in the event of any action or proceeding which
              finally adjudicates the liability of the Sellers' Agent for
              its gross negligence or willful misconduct.

              (d)  All of the indemnities, immunities and powers granted to the
              Sellers' Agent under this Agreement shall survive the
              Closing and/or any termination of this Agreement.

         (c)  Notices.  Any notice given to the Sellers' Agent pursuant to this
         Agreement or any other agreement, document, instrument or
         certificate contemplated hereby shall constitute effective notice
         to all Sellers.  Publicker, Acquisition Sub, the Surviving
         Corporation and any other Person may rely on any notice, consent,
         election or other communication received from the Sellers' Agent
         as if such notice, consent, election or other communication had
         been received from all Sellers.

         (d)  Resignation or Removal; Successor Agent.

              (a)  The Sellers' Agent may resign upon 20 days' prior written
              notice to Publicker, the Surviving Corporation and each
              Seller, provided, that no such resignation may take effect
              unless a successor Sellers' Agent shall have been duly
              appointed and shall have accepted such appointment and
              notice thereof shall have been given as set forth in Section
              14.4(b).  Any successor Sellers' Agent shall be a natural
              person.
  
              (b)  Upon the resignation of the Agent, Sellers shall appoint a
              successor Sellers' Agent by written consent of Sellers
              holding 51% of the outstanding Company Shares immediately
              prior to the Effective Time, and any successor Sellers'
              Agent so appointed shall constitute the Sellers' Agent as
              provided in this Section 14 to the same effect as if such
              successor Sellers' Agent had been named in this Section 14. 
              Sellers shall give Publicker and the Surviving Corporation
              written notice of the appointment of and acceptance of
              appointment by the successor to such Sellers' Agent,
              including a copy of the written consent of Sellers relating
              thereto, the executed acceptance of appointment by the
              successor to such Sellers' Agent, and the successor Sellers'
              Agent's address (including telephone and telecopy numbers)
              as soon as practicable after any such appointment.  The
              Sellers' Agent shall give Publicker and the Surviving
              Corporation written notice of the resignation of such
              Sellers' Agent as well as of the appointment of and
              acceptance of appointment by the successor to such Sellers'
              Agent, including the executed acceptance of appointment by
              the successor to such Sellers' Agent and the successor
              Sellers' Agent's address (including telephone and telecopy
              numbers) as soon as practicable after any such resignation
              and appointment.  Any such resignation or appointment shall
              not be effective against Publicker or the Surviving
              Corporation until such notices shall have been given.

         15.7, a Person shall not be considered a party to this Agreement
         and shall have no rights under this Agreement as a Seller or

         this Agreement may be amended by action taken by or on behalf of
         the respective boards of directors of Publicker, Acquisition Sub
         and the Company at any time; provided, however, that no amendment
         shall be made which under the DGCL or FBCA would require the
         further approval of the shareholders of Acquisition Sub or the
         Company (as the case may be) without obtaining such approval. 
         This Agreement may be amended only by a writing signed by
         Publicker, Acquisition Sub, the Company and each Seller who has
         delivered a signature page to this Agreement prior to such
         amendment date.  No amendment of this Agreement shall be required
         to (a) effect the addition of any Person as a Seller under this
         Agreement (or the modification of Schedule 7.5 in connection
         therewith) in accordance with Section 15.7 or (b) effect the
         replacement of any Schedule to this Agreement in accordance with
         Section 9.16.  Any provision of this Agreement may be waived at
         any time by a writing signed by the party which is entitled to the
         benefits thereof.

         (i)  Further Assurances.  Each of the parties hereto agrees that it
         will, from time to time after the date of this Agreement, execute
         and deliver such other certificates, documents and instruments and
         take such other action as may be reasonably requested by any of
         the other parties to carry out the Contemplated Transactions.

         (j)  Severability.  The invalidity of any provision of this Agreement
         shall not affect any other provision of this Agreement, which
         shall remain in full force and effect.

         (k)  Counterparts.  This Agreement may be executed in any number of
         counterparts, each of which shall be deemed an original, but all
         of which together shall constitute one and the same instrument.






     IN WITNESS WHEREOF, the parties hereto have executed this
instrument as of the date and year first above written.
