                          PART I - FINANCIAL INFORMATION


 ITEM 1.  Notes to Consolidated Financial Statements (Unaudited)

 1.  In the  opinion of management, the  accompanying consolidated condensed
     financial  statements  contain all  adjustments  (consisting  of normal
     recurring adjustments) necessary to present fairly Selas Corporation of
     America's consolidated financial position as  of September 30, 1998 and
     December 31, 1997, and  the consolidated results of its  operations for
     the three  and  nine  months ended  September  30, 1998  and  1997  and
     consolidated  statements of shareholders' equity and cash flows for the
     nine  months then  ended.    The  interim  operating  results  are  not
     necessarily  indicative of  the results  to be  expected for  an entire
     year.

 2.  The accounting policies followed by the Company are set forth in note 1
     to the Company's financial statements in the 1997 Selas Corporation of
     America Annual Report.

 3.  Acquisitions

     In  February, 1998,  the Company  acquired the  stock of CFR,  a Paris,
     France  firm  in  the  engineered  industrial  furnace business.    The
     principal  market  served by  CFR  is engineered  batch  and continuous
     furnaces for heat treating  both ferrous and non-ferrous metals,  along
     with  supplying furnaces  for the  hardening and  etching of  glass and
     ceramic tableware.  CFR had sales for the year ended  December 31, 1997
     of 107.5  million French francs  (FF) or  approximately $18.3  million.
     The  purchase price  was 15  million FF  or approximately  $2.5 million
     which was paid for  by additional bank borrowings of 15 million FF at a
     fixed rate of 5.65% which requires quarterly payments of FF 750,000 for
     5 years.   During the second quarter of 1998, the Company also acquired
     the remaining minority  interest in  SEER, a Givry,  France firm  which
     specializes  in  automating,   controlling  and  monitoring  industrial
     processes.   The majority interest in  SEER was acquired by the Company
     with the purchase of CFR.

     In May, 1998,  a subsidiary of  the Company acquired  the stock of  IMB
     Electronic  Products, Inc., a Santa  Fe Springs, CA  firm that produces
     precision electro-mechanical parts for the telecommunications and audio
     industries.  IMB  manufactures film capacitors which are energy storage
     devices used primarily to resist changes in voltage.  IMB had sales for
     fiscal 1997 of $2.9 million.  The purchase price was $1.3 million which
     was paid in cash.

     These acquisitions have been accounted for as purchases and the results
     of  CFR,  SEER  and  IMB    have  been  included  in  the  accompanying
     consolidated financial statements since  the dates of the acquisitions.
     The purchase price was allocated to assets and liabilities based on the
     estimated  fair value  as  of  the dates  of  the  acquisitions.   Such
     allocations  have been  based on  preliminary estimates  of fair  value
     which may be revised at a later date.

     In  February   1997,  the  Company  acquired  the  assets  and  certain
     liabilities of the Rodan Division of Ketema, Inc.  Under the

 ITEM 1.  Notes to Consolidated Financial Statements (Unaudited)

 3.   Acquisitions (Continued)

      Purchase Agreement, the Company agreed to deliver to Ketema additional
      purchase price, payable in the Company's Common Shares, based upon the
      performance of the acquired  business during a one year  period ending
      in February 1998.  In October 1998, the Company tendered 23,557 Common
      Shares to Ketema in satisfaction of this requirement.

 4.   Inventories consist of the following:

                                       September 30,   December 31,
                                            1998            1997    

        Raw material                    $3,695,033      $3,054,544
        Work-in-process                  4,939,476       2,721,964
        Finished products and
          components                     5,552,622       4,222,632

                      Total             $14,187,131     $9,999,140
                                        ===========     ==========
 5.    Income Taxes

       Consolidated income taxes for the nine month  periods ended September
       30,  1998  and  1997 are  $468,000  and  $2,386,000  which result  in
       effective tax  rates of 12.6%  and 39.3%, respectively.   The rate of
       tax  in relation to  pre-tax income in  1998 is lower  because in the
       second quarter,  the Company reduced the  valuation allowance applied
       against domestic postretirement benefit  obligations by $724,512  and
       against  certain  domestic  employee  pension  plan   obligations  by
       $33,694.    The reduction  in the  valuation  allowance was  based on
       several  factors  including:    recent  acquisitions,  future  income
       projections, past earnings history and trends, reasonable and prudent
       tax planning  strategies, and the expiration  dates of carryforwards.
       The Company has  determined that it is more likely  than not that the
       $758,206  of deferred  tax assets  will be  realized.   The remaining
       valuation allowance of  approximately $863,971 is maintained  against
       deferred tax assets  which the  Company has determined  are not  more
       than likely to be realized.

 6.    Legal Proceedings

       The Company  is a defendant along  with a number of  other parties in
       approximately  215  lawsuits  as of  December  31,  1997  (155 as  of
       December  31,  1996)  alleging  that  plaintiffs  have  or  may  have
       contracted  asbestos-related  diseases as  a  result  of exposure  to
       asbestos products  or equipment  containing asbestos  sold by  one or
       more named defendants.  Due to the noninformative nature of

 6.   Legal Proceedings (continued)

       the  complaints, the  Company  does  not  know  whether  any  of  the
       complaints  state valid claims against  the Company.   The Company is
       also one of approximately 500 defendants  in a class action on behalf
       of approximately 2,700 present  or former employees of a  Texas steel
       mill  alleging that  products supplied  by the  defendants  created a
       poisonous atmosphere  that caused  unspecified physical harm.   These
       cases are being defended by  one or more of the Company's   insurance
       carriers  presently known  to be  "at risk."   The  lead  carrier has
       settled  approximately  11  and   17    claims  in  1997   and  1996,
       respectively, with no request  for the Company to participate  in any
       settlement.     The lead carrier  has informed  the Company  that the
       primary policy for the  period July 1, 1972  - July 1, 1975  has been
       exhausted and that  the lead carrier will no longer provide a defense
       under that policy.   The Company has requested that  the lead carrier
       substantiate   this   situation.      The   Company   has   contacted
       representatives of the Company's excess insurance carrier for some or
       all  of this period.  The Company  does not believe that the asserted
       exhaustion  of the  primary insurance  coverage for this  period will
       have a material adverse effect on the financial condition, liquidity,
       or  results of  operations  of the  Company.   Management  is of  the
       opinion that the number of insurance carriers involved in the defense
       of the suits  and the significant  number of policy years  and policy
       limits to  which these  insurance carriers  are insuring the  Company
       make the ultimate disposition  of these lawsuits not material  to the
       Company's consolidated financial position or results of operations.

       In 1995, a dispute which was submitted to arbitration,  arose under a
       contract  between  a  customer  and  a  subsidiary  of  the  Company.
       Substantial claims were asserted against the subsidiary Company under
       the  terms  of  the  contract.    The  Company  recorded  revenue  of
       approximately $1,400,000 in 1994 and has an uncollected receivable of
       $140,000.   The Company believes  that the disposition  of this claim
       will  not  materially  affect  the  Company's  consolidated financial
       position or results of operations.

          and Results of Operations                                 

 Consolidated net sales decreased to $25.2 million and $72.3 million for the
 three and  nine months ended September  30, 1998 compared to  $28.3 million
 and $86.3 million for the same periods ended September 30, 1997.  Net sales
 for  the heat  processing  segment decreased  to  $12.1 million  and  $32.9
 million  for the  three and  nine  month periods  ended September  30, 1998
 compared to  $16.4 million and  $51 million for  the same periods  in 1997.
 The decline in sales for the three  and nine month periods was due in  part
 to lower sales backlog of large engineered contracts as of the beginning of
 fiscal year 1998  as compared to  the beginning of  fiscal year 1997.   The
 February, 1998 acquisition  of CFR,  a French Company,  generated sales  of
 $3.5  million and  $8.6  million for  the  quarter and  year-to-date  which
 partially offset  some of  the sales  decline for the  periods.   Sales and
 earnings of large engineered contracts are recognized on the percentage-of-
 completion  method  and  generally  require  more  than  twelve  months  to
 complete.   Consolidated backlog for the  heat processing segment was up to
 $26.4 million  at September 30, 1998 compared to $16.9 million for the same
 period  in 1997.  Sales  for the Company's  precision electromechanical and
 plastics components segment increased to $9.5 million and $27.4 million for
 the three  and nine month periods ended September 30, 1998 compared to $8.6
 million and $24.6 million  for the same periods  in 1997.  The increase  in
 sales  is partially  attributable  to the  acquisition  of RTI  Electronics
 (RTIE) in February 1997 and IMB Electronic Products Inc. (IMB) in May 1998.
 Also impacting this segment's  increased sales were higher sales  of hybrid
 electromechanical systems and plastic component sales to its hearing health
 customers.  Sales for the tire holders, lifts and  related products segment
 increased to  $3.6 million and  $12 million for  the three and  nine months
 ended September 30, 1998 compared to $3.3 million and $10.7 million for the
 same periods  last year.  The increased sales  are due to higher unit sales
 of the Company's tire lifts to the automotive industry.

 The Company's gross profit margin as a percentage-of-sales increased to 23%
 and 24.3%  for the three  and nine month  periods ended September  30, 1998
 compared to  19.3% and 21.4% for  the same periods  in 1997.   Gross profit
 margins for the heat processing segment increased to 20% and  20.9% for the
 three and nine months ended September  30, 1998 compared to 11.7% and 15.6%
 for the same periods in 1997.   Gross profit in the heat processing segment
 vary   markedly  from   contract   to  contract,   depending  on   customer
 specifications and other  conditions related  to the contract.   The  third
 quarter's gross profit margin  in 1997 was lower  than the current  quarter
 due  to higher costs for a contract  that was nearing completion last year.

 decreased to  28.5% and 30.5%  for the three  and nine month  periods ended
 September 30,  1998 compared to  35.3% and  35.7% for the  same periods  in
 1997.   The lower gross  profit margins are  partially attributable  to the
 acquisitions  of RTIE  in February,  1997  and IMB  in May,  1998 as  their
 products, while  profitable,  do not  achieve the  historical gross  profit
 margins of this business  segment.  Also impacting  the lower gross  profit
 margins, but to  a lesser degree, is  the mix of product  sales between the
 periods as precision electromechanical  and plastic components have varying
 gross profit  margins.  Further impacting the  gross profit margins for the
 quarter was severe price competition from RTIE's competition.  Gross profit
 margins for the tire holders, lifts and related products increased to 18.7%
 and 19.8% for  the three and  nine month periods  ended September 30,  1998
 compared to 15% and 16.2% for the same periods in 1997.  The improved gross
 profit margins are due  to increased units sold and  improved manufacturing
 efficiencies.

 Selling, general and administrative expenses  increased to $4.4 million and
 $13.3  million for  the  three and  nine months  ended  September 30,  1998
 compared to  $3.7 million and $11.6  million for the same  periods in 1997.
 The increase is primarily due to higher selling and administrative expenses
 for the companies acquired this year, CFR in February and IMB in May.

 Interest expense  for the three  and nine  months ended September  30, 1998
 increased  to $299,000 and $841,000  compared to $247,000  and $765,000 for
 the same periods in 1997.  The increase in expense is due to an increase in
 outside  borrowings  in the  current year.    Interest income  decreased to
 $35,000 and $82,000 for the three and nine months ended  September 30, 1998
 compared to $72,000 and $207,000 for the  same periods in 1997 due to lower
 balances available for investment.

 Other income (expense) includes  gains on foreign exchange of  $215,000 and
 $222,000 for the three and nine months ended September 30, 1998 compared to
 a gain of $161,000 for the three months ended September 30, 1997 and a loss
 of $68,000 for the nine months ended September 30, 1997.
 Consolidated  income taxes for the  nine month periods  ended September 30,
 1998  and 1997 are  $468,000 and $2,386,000  which result in  effective tax
 rates of  12.6% and 39.3%,  respectively.  The  rate of tax  in relation to
 pre-tax income in 1998 is lower because in the second  quarter, the Company
 reduced  the valuation  allowance applied  against domestic  postretirement
 benefit  obligations  by $724,512  and  against  certain domestic  employee
 pension plan obligations by

          and Results of Operations (Continued)                     

 $33,694.   The reduction in  the valuation allowance  was based  on several
 factors including:   recent  acquisitions, future income  projections, past
 earnings  history   and  trends,   reasonable  and  prudent   tax  planning
 strategies, and the  expiration dates  of carryforwards.   The Company  has
 determined that  it is more likely  than not that the  $758,206 of deferred
 tax  assets will  be  realized.    The  remaining  valuation  allowance  of
 approximately $863,971  is maintained against deferred tax assets which the
 Company has determined are not more than likely to be realized.

 Consolidated  net  income  for the  three  and  nine  months periods  ended
 September  30, 1998 is $917,000  and $3,243,000 compared  to $1,139,000 and
 $3,680,000 for the same periods in 1997.  The lower earnings in the current
 year are  due to  lower sales and  higher selling  and administrative  (due
 primarily to recent acquisitions) partially offset by improved gross profit
 margins.  The lower  year-to-date earnings are also favorably impacted by a
 reduction   in  the   valuation  allowance   of  deferred  tax   assets  of
 approximately $750,000.

 Liquidity and Capital Resources

 Consolidated net working  capital decreased to  $18.4 million at  September
 30, 1998 from $18.6 million at December 31, 1997.  The $.2 million decrease
 is  due to the  acquisition of CFR  and IMB, dividend  payments and capital
 additions,  partially  offset by  the earnings  for  the nine  months ended
 September  30, 1998.   The major  changes in components  of working capital
 were  higher  current  liabilities  of  $5.4  million,  due  to  short-term
 borrowings to finance the  CFR and IMB acquisitions, higher  inventories of
 $4.2 million  (primarily acquisition related)  and higher cash  balances of
 $1.1 million.

 In  May, 1998,  a  subsidiary of  the  Company acquired  the  stock of  IMB
 Electronic  Products  Inc.  (IMB)  of  Santa  Fe  Springs,  California  for
 approximately  $1.3  million  in cash.    IMB  is  a  manufacturer of  film
 capacitors, energy  storage devices  used primarily  to  resist changes  in
 voltage.   The Company's  sales for the  year ended December  31, 1997 were
 approximately $3 million.

 In February, 1998, the Company  acquired the stock of CFR, a  Paris, France
 firm in the engineered  industrial furnace business.  The  principal market
 served by CFR is engineered batch and continuous furnaces for heat treating
 both  ferrous and non-ferrous metals, glass and ceramic tableware.  CFR had
 sales  for the year ended December 31,  1997 of 107.5 million French francs
 (FF) or approximately $18.3 million.   The purchase price was 15 million FF
 or  approximately $2.5  million and the  assumption of  certain liabilities
 which was  paid for by  additional bank borrowings  of 15 million  FF which
 will be paid off over five years at a fixed annual interest rate of 5.65%.

 ITEM 2.  Management's Discussion and Analysis of Financial
          Condition and Results of Operations (Continued)  

 The Company currently has a program underway to remediate by March 31, 1999
 all of the Company's significant computer systems that are not Year 2000
 compliant. The  program is divided into three major components:  (1) identif-
 ication of  all  information  technology  systems  ("IT  Systems")  and non-
 information technology systems ("Non-IT Systems") that are not Year 2000 com-
 pliant; (2)  repair or replacement of the identified  non-compliant systems;
 and (3) testing of the  repaired or replaced systems.  Approximately  25% of
 the IT Systems the Company uses  are in-house developed.  Commercially devel-
 oped software,  the majority of which is periodically upgraded through exist-
 ing maintenance contracts, accounts for the balance.  Part (1) and (2) of the
 Company's  Year  2000  program  are  substantially  complete.    Review  of
 accounting  and financial reporting systems is finished, and the Company is
 continuing to review Non-IT  Systems that have embedded microprocessors  in
 various  types of equipment.   Part (2), repairing  and replacing, has been
 completed for both in-house and commercially developed IT systems.  Part (3),
 testing,  is underway  and the  Company has  targeted March  31, 1999  as a
 completion date.

 The Company has been inquiring of certain key suppliers and business partners
 about their Year 2000 readiness.  While no assurances can be given that key 
 suppliers and  business partners will remedy their own Year 2000 issues, the
 Company to date has not identified any material impact on its ability to con-
 tinue normal business operations with  suppliers or other third parties who 
 fail to address the Year 2000 issue.

 Actual  costs associated  with implementation  of  the Company's  Year 2000
 program  are expected to be  insignificant to the  Company's operations and
 financial  condition.  Costs of $75,000 to $100,000, primarily for software
 and outside  services, are expected  to be incurred.   Significantly all of
 these costs are expected to be expensed.

 The Company  will continue to monitor  and evaluate the impact  of the Year
 2000 issue on its operations.   Until the Company has completed   the final
 testing  part of its  program, the risks from  potential Year 2000 failures
 cannot be  fully assessed.  Due  to this situation, the  Company cannot now
 begin  final contingency plans.  These plans will be developed as potential
 Year 2000 failures are identified in the final testing stages. Nevertheless,
 if remediation is not accomplished successfully in a timely fashion and suc-
 cessful contingency plans are not implemented, the Company believes the Year
 2000 issue could have a material adverse effect on the Company.

 ITEM 2.  Management's Discussion and Analysis of Financial
          Condition and Results of Operations (Continued)  

 A  significant portion of the heat processing segment sales are denominated
 in foreign currencies, primarily  the French franc.  Generally,  the income
 statement  effect of changes in  foreign currencies is  partially or wholly
 offset by the  European subsidiaries' ability  to make corresponding  price
 changes in the local currency.   

 On  January 1,  1999, eleven of  fifteen member  countries of  the European
 Union  are scheduled  to  establish fixed  conversion  rates between  their
 existing  currencies ("legacy currencies")  and one  common currency  - the
 Euro.   The Euro will  then trade on currency exchanges  and may be used in
 business  transactions.  The conversion to the Euro will eliminate currency
 exchange risk between the member countries.  Beginning in January 2002, new
 Euro-denominated bills and coins will be issued, and legacy currencies will
 be withdrawn from circulation.   The Company has recognized  this situation
 and is currently in the  process of developing a plan to  address any issue
 being raised by the currency conversion.   Possible issues include, but are
 not limited  to,  the need  to  adapt  computer and  financial  systems  to
 recognize Euro-denominated  transactions,  as well  as  the impact  of  one
 common currency  on pricing.   The Company anticipates  these issues to  be
 resolved in  conjunction with any  Year 2000 issues.   However, due  to the
 uncertainty  of this  matter, the  Company can  not guarantee  any definite
 outcome or result on operations.

 In  June  1998, the  Financial  Accounting  Standards  Board (FASB)  issued
 Statement of Financial  Accounting Standard (SFAS) No. 133, "Accounting for
 Derivative   Instruments  and   Hedging   Activities".     This   statement
 standardizes  the   accounting   for  derivative   instruments,   including
 derivative instruments embedded  in other contracts,  by requiring that  an
 entity recognize  those items as assets or  liabilities in the statement of
 financial  position and  measure  them at  fair  value.   The  statement is
 effective for fiscal  year beginning after June  15, 1999.   Management has
 not yet determined the impact that  the adoption of this statement may have
 on earnings, financial condition or liquidity of  the Company.  The Company
 plans to adopt  SFAS No. 133  as permitted by  this accounting standard  by
 January 1, 2000.

 In June, 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
 an  Enterprise  and  Related  Information."    This  statement  establishes
 standards  for reporting  information  about operating  segments in  annual
 financial  statements and  requires  selected  information about  operating
 segments  in interim  financial reports  issued to  shareholders.   It also
 establishes standards for related  disclosures about products and services,
 geographic areas and major customers.

 ITEM 2.  Management's Discussion and Analysis of Financial
          Condition and Results of Operations (Continued)  

 In  February, 1998,  the FASB  issued SFAS  No. 132  "Employers' Disclosure
 about Pensions and Other Postretirement Benefits."   This Statement revises
 employers'  disclosures about  pension  and  other  postretirement  benefit
 plans.  It does not change the measurement or recognition of those plans.

 The  Company plans to adopt  these accounting standards  in connection with
 the preparation of the December 31, 1998  consolidated financial statements
 as permitted by SFAS No. 131 and No. 132.  The  adoption of these standards
 is  not expected  to  have  a  material  impact  on  consolidated  results,
 financial condition, or long-term liquidity.  

 In March 1998, the Accounting  Standards Executive Committee (AcSEC) issued
 Statement  of Position  (SOP) 98-1  "Accounting For  the Costs  of Computer
 Software Developed or Obtained for Internal Use."  The SOP is effective for
 financial statements for fiscal years beginning after December 15, 1998.

 In April 1998, the Accounting  Standards Executive Committee (AcSEC) issued
 Statement  of  Position (SOP)  98-5, "Reporting  as  the costs  of Start-Up
 Activities."   This  SOP provides  guidance on  the financial  reporting of
 start-up costs and organization  costs.  The SOP requires costs  related to
 start-up  activities and organization costs  be expensed as  incurred.  The
 statement is effective for  financial statements for fiscal  year beginning
 after December 15, 1998.

 The Company plans to adopt these  SOP's in connection with the preparations
 of  the December 31, 1999 consolidated financial statements as permitted by
 SOP  98-1 and  98-5.   The  adoption of  these  standards will  not  have a
 material impact on consolidated results, financial conditions, or long-term
 liquidity.

 The Company believes  that its present  working capital position,  combined
 with  funds  expected to  be generated  from  operations and  the available
 borrowing  capacity through its  revolving credit loan  facilities, will be
 sufficient to meet  its anticipated cash  requirements for operating  needs
 and capital expenditures for 1998.

 Forward-Looking and Cautionary Statements

 The Company and its representatives  may from time to time make  written or
 oral forward-looking statements, including those contained in the foregoing
 Management's Discussion and Analysis.  Actual results may differ materially 
 from those contained in or implied by such forward-looking statements due to
 competition, foreign currency and other global economic factors, the failure 
 of the Company or its material suppliers or customers to remedy Year 2000 is-
 sues and other factors. In order to take advantage of the "safe harbor" prov-
 isions of the Private Securities Litigation Reform Act of 1995, the Company 
 has identified in its Annual Report on Form 10-K for the year ending December
 31, 1997, certain other important factors which could cause the  Company's  
 actual results, performance or achievement to differ materially  from those
 that may be contained in or implied by any forward-looking statement made by

          FOR VALUE RECEIVED, the undersigned SELAS CORPORATION OF AMERICA, a
Pennsylvania corporation, with principal offices at 2034 Limekiln Pike, Dresher,
Pennsylvania 19025 (the "Borrower"), promises to pay to the order of FIRST UNION

principal balance hereof payable as set forth below. All such principal and
interest shall be payable in lawful money of the United States of America in
immediately available funds on a Business Day at the offices of the Bank set
forth above.

          Until maturity (whether by acceleration or otherwise), the outstanding
principal balance hereunder shall bear interest at the rates and shall be
payable at the times and in the manner set forth in the Credit Agreement.
Subsequent to maturity, including after judgment, interest on the outstanding
principal balance hereunder shall accrue at an annual rate which shall be two
percent (2%) above the rate of interest otherwise payable hereunder.

          This Amended and Restated Revolving Credit Note (herein, the "Note")

hereof, by and among Borrower, Deuer Manufacturing, Inc., Resistance Technology,
Inc., RTI Electronics, Inc., RTI Export, Inc. and the Bank, (as amended from
time to time, the "Credit Agreement"). Capitalized terms used but not otherwise
defined in this Note shall have the respective meanings given to such terms in
the Credit Agreement. Reference is made to the Credit Agreement for a statement
of the respective rights and obligations of the parties and the terms and
conditions therein provided under which the principal hereof and accrued
interest thereon, if any, may become immediately due and payable. The collateral
specified in the applicable Collateral Security Documents shall secure the
obligations of Borrower under this Note.

hereunder shall be limited at all times to the actual aggregate outstanding
indebtedness to Bank (principal, interest and fees) under the Revolving Credit
Facility, as established by Bank's books and records, which books and records
shall be conclusive absent manifest error.

          The occurrence of an Event of Default under the Credit Agreement
constitutes an Event of Default under this Note and entitles Bank, in
accordance with the Credit Agreement, to declare this Note immediately due
and payable in full.

          Borrower hereby waives presentment, demand for payment, notice of
dishonor or acceleration, protest and notice of protest, and any and all other
notices or demands in connection with the delivery, acceptance, performance,
default or enforcement of this Note, excepting any notice requirements set forth
in the Credit Agreement.

          In the event any interest rate applicable hereto is in excess of the
highest rate allowable under applicable law, then the rate of such interest will
be reduced to the highest rate not in excess of such maximum allowable interest
and any excess previously paid by Borrower shall be deemed to have been applied
against principal.
          If Borrower subscribes to Bank's cash management services and such
services are applicable to the Revolving Credit Facility, the terms of such
service shall control the manner in which funds are transferred between the
applicable demand deposit account and the Revolving Credit Facility for credit
or debit to the line of credit.

          BORROWER HEREBY AUTHORIZES AND EMPOWERS ANY ATTORNEY OR ATTORNEYS OR
THE PROTHONOTARY OR CLERK OF ANY COURT OF THE COMMONWEALTH OF PENNSYLVANIA, OR
ELSEWHERE, TO APPEAR FOR BORROWER AT ANY TIME FOLLOWING THE OCCURRENCE OF AN
EVENT OF DEFAULT UNDER THE CREDIT AGREEMENT IN ANY SUCH COURT IN AN APPROPRIATE
ACTION THERE OR ELSEWHERE BROUGHT OR TO BE BROUGHT AGAINST BORROWER BY ANY BANK

COURT THERE OR ELSEWHERE TO BE HELD AND THEREIN TO CONFESS OR ENTER JUDGMENT
AGAINST BORROWER FOR ALL SUMS DUE BY BORROWER TO BANKS UNDER THIS NOTE AND THE
CREDIT AGREEMENT, TOGETHER WITH THE COSTS OF SUIT AND REASONABLE ATTORNEYS'
FEES, AND FOR SO DOING THIS NOTE OR COPY HEREOF VERIFIED BY AFFIDAVIT SHALL BE A
SUFFICIENT WARRANT.

          BORROWER HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVES ANY
RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION HEREON OR
ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE OR THE CREDIT AGREEMENT OR
THE MAKING OF THE LOAN OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN) OR ACTIONS OF BORROWER OR BANKS OR ANY OF THEM. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR BANK'S ENTERING INTO THE CREDIT
AGREEMENT.

          BORROWER ACKNOWLEDGES THAT IT HAS HAD THE ASSISTANCE OF COUNSEL IN THE
REVIEW AND EXECUTION OF THIS NOTE AND FURTHER ACKNOWLEDGES THAT THE MEANING AND
EFFECT OF THE CONFESSION OF JUDGMENT AND WAIVER OF JURY TRIAL HAVE BEEN FULLY
EXPLAINED TO SUCH BORROWER BY SUCH COUNSEL.

          Borrower's liability under this Note shall include all fees and
expenses provided in the Credit Agreement.

          This Note shall be binding upon Borrower and its successors and
assigns and shall inure to the benefit of the Bank and its successors and
assigns and shall be governed as to validity, interpretation and effect by the
laws of the Commonwealth of Pennsylvania.

certain Amended and Restated Revolving Credit Note, dated July 21, 1995
(together with all amendments and modifications thereto, the "Existing Note"),
by the Borrower in favor of the Bank.  This Note is not intended to extinguish

Conversion  shall, within the restrictions specified above, specify (A) the date
of such Conversion, (B) the particular Advances to be Converted, and (C) if such
Conversion is into a LIBOR Loan, the duration of the initial Interest Period for
such LIBOR Loan.   Each notice  of Conversion shall  be irrevocable and  binding
upon the Borrower.

                 (iii)  If the Borrower shall fail to select the duration of any
Interest  Period for any LIBOR Loan in  accordance with the provisions contained
in  definition  of Interest  Period,  the  Bank  will  forthwith so  notify  the
Borrower, whereupon each such LIBOR Loan will automatically, on the  last day of
the then existing  Interest Period therefor,  Convert into a LIBOR  Market Index
Loan.

            (d)  Default  Rate. Notwithstanding  the foregoing  subsections (a),
(b) and  (c), upon  the occurrence  and during  the continuance of  an Event  of
Default or  Default hereunder, including after maturity (whether by acceleration
or otherwise) and before and  after judgment, the Borrower hereby agrees  to pay
to Bank  interest on the outstanding principal balance  of the Loans and, to the
extent permitted by  law, overdue interest with respect thereto,  at the rate of
two percent (2%) per annum above the interest rates otherwise applicable to such
Loans pursuant to Sections 2.5(a), (b) and (c), respectively.

     2.6    ADVANCES UNDER THE REVOLVING CREDIT FACILITY.

            (a)  The Borrower shall give  the Bank written notice (which  notice
may be  transmitted by telecopier,  provided that the Bank  receives an original
executed Advance Request Form within 24 hours thereafter) not later than  eleven
o'clock (11:00) a.m.  on the date of each requested  Advance under the Revolving
Credit Facility in the case of Base Rate Loans and LIBOR Market Index Loans, and
on the date which is three (3) Business Days prior to the date of each requested
Advance  under the  Revolving Credit  Facility in  the case  of LIBOR  Loans, in
either case specifying the date,  amount, Interest Period (in the case  of LIBOR
Loans), and purpose thereof.   Such notice shall be  in the form of  the Advance
Request  Form attached  hereto as  Exhibit A,  shall be  certified by  the chief
executive or chief financial  or accounting officer (or the  equivalent thereof)
of the Borrower and shall contain the following information and representations,
which  shall be  deemed affirmed  and true  and correct  as of  the date  of the
requested Advance:

                 (i)    the  aggregate amount  of the  requested Advance,  which
shall be in  multiples of $50,000.00 but not less than the lesser of $100,000.00
or the unborrowed balance of the Revolving Credit Commitment;

                 (ii)   confirmation of the Borrower's compliance  with Sections
6.15 through 6.18 following such Advance; and

                 (iii)  statements  that the representations  and warranties set
forth in Section 4 hereof (other than those that relate to a specific date only)
are true  and correct as  of the  date thereof; no  Event of Default  or Default
hereunder  has  occurred and  is then  continuing; and  that  there has  been no
material  adverse change in the  financial condition, operations  or business of
the Borrower and  its Consolidated Subsidiaries since the date  of the quarterly
and  audited annual financial statements most recently delivered by the Borrower
to the Bank pursuant to Sections 4.8(a), 6.2 and 6.3 of this Agreement.

            (b)  Subject to the satisfaction of the terms and conditions hereof,
the Bank shall make the requested Advance available to the Borrower by crediting
such amount to the Borrower's deposit account  with the Bank, or by wiring  such
funds in accordance with the  instructions set forth on Schedule IV  hereto, not
later than two o'clock (2:00) p.m. on the day of the requested Advance.

            (c)  Each  request for an Advance pursuant to this Section 2.6 shall
be irrevocable and binding on the Borrower.

     2.7    REDUCTION OF REVOLVING  CREDIT COMMITMENT.  The  Borrower shall have
the right at any time and from time to  time, upon five (5) Business Days' prior
written notice to  the Bank, to reduce the Revolving  Credit Commitment in whole
or  in part in increments  aggregating $250,000.00 or  multiples thereof without
penalty or  premium, provided that (i)  on the effective date  of such reduction
the Borrower shall  make a prepayment under the Revolving  Credit Facility in an
amount, if any, by which the aggregate outstanding principal balance outstanding
under the Revolving Credit Facility  exceeds the amount of the  Revolving Credit
Commitment, as then so reduced, together  with accrued interest on the amount so
prepaid; and (ii)  notwithstanding any such partial or total  reduction, any and
all  Collateral pledged by  the Borrower shall continue  to secure the remaining
obligations of the  Borrower as provided  herein and in the  Collateral Security
Documents  to which the  Borrower is  a party.   Any reduction  of the Revolving
Credit Commitment  pursuant to  this Section  2.7 shall  be  permanent, and  the
Revolving Credit Commitment cannot  thereafter be restored or increased  without
the written consent of the Bank.

     2.8    REVOLVING LOAN TERMINATION DATE.  The Revolving Credit Commitment of
the Bank shall terminate on the Revolving Credit Termination Date without notice
or demand.  The Revolving Credit Termination Date may be extended by the parties
for successive one-year periods as  follows: (i) not less than ninety  (90) days
prior to the  then applicable  Revolving Credit Termination  Date, the  Borrower
shall  deliver a  written  request for  such  extension to  the  Bank; and  (ii)
following the receipt of  such request, and not less than thirty (30) days prior
to such  Revolving Credit Termination Date,  the Bank shall notify  the Borrower
whether  the  Bank has  approved the  Borrower's request  for an  extension. The
failure of the Bank to send the Borrower written approval of its request  for an
extension  shall be  deemed a denial  of such  request.  The  Bank's decision to
approve  or  decline  such  extension  request  shall  be  in  the  Bank's  sole
discretion.

     2.9    PAYMENTS.  All  payments  of  principal, interest,  fees  and  other
amounts due  hereunder, including any prepayments thereof,  shall be made by the
Borrower  to the  Bank  in immediately  available  funds before  twelve  o'clock
(12:00)  noon, Philadelphia,  Pennsylvania  time, on  any  Business Day  at  the
principal office of  the Bank  located in Philadelphia,  Pennsylvania. The  Bank
may, and the Borrower  authorizes the Bank to,  debit its account, if any,  with
the  Bank for the  amount of any  payment as and  when such payment  becomes due
hereunder. The Bank will  notify the Borrower promptly following  the occurrence
of such  debit. Notwithstanding the foregoing,  the Bank and  any Affiliate may,
and the  Borrower authorizes the  Bank and any  Affiliate to, debit  any account
and/or certificate  of deposit maintained by  the Borrower with the  Bank or any
Affiliate for the amount  of any payment, as  and when such payment  becomes due
hereunder, whether such payment  is for accrued interest, principal  or expense,
even  if debiting such account results in a loss or reduction of interest to the
Borrower or  the imposition of a  penalty applicable to the  early withdrawal of
time  deposits. Such authorization shall not affect the Borrower's obligation to
pay as  and when  due all amounts  payable hereunder, whether  or not  there are
sufficient funds  in any accounts of  the Borrower. The Borrower  agrees to fund
its respective  accounts from  time to  time in amounts  sufficient to  make the
payments hereunder as and when they become due. The foregoing rights of the Bank
and its Affiliates to debit the Borrower's accounts shall be in addition to, and
not in limitation of, any rights of  set-off which the Bank and/or any Affiliate
may have hereunder  or under any  of the Notes,  any of the Collateral  Security
Documents, or otherwise.

     2.10   COMMITMENT  FEE. The Borrower shall pay to the Bank a non-refundable
commitment fee of 18.75 basis  points per annum on the unborrowed portion of the
Revolving  Credit Commitment from the  date hereof through  the Revolving Credit
Termination Date,  which  fee shall  be  payable at  the  offices of  the  Bank,
quarterly in arrears on the first day  of each January, April, July and October,
as billed by the  Bank. The commitment fee shall  be calculated on the  basis of
the actual number of days elapsed over a year of three hundred sixty (360) days.
For purposes of calculating the commitment  fee payable pursuant to this Section
2.10, the face  amount of all issued, outstanding and  undrawn Letters of Credit
shall be deemed to have been borrowed under Section 2 hereof.

     2.11   REQUIREMENTS OF LAW. In the event that the enactment or promulgation
after the date hereof of any law, regulation,  treaty or directive or any change
therein or in  the interpretation or  application thereof  or compliance by  the
Bank  with any request or  directive made after the  date hereof (whether or not
having the  force of law) from any central bank or other governmental authority,
agency or instrumentality:

            (a)  does  or  shall  subject  the  Bank to  any  tax  of  any  kind
whatsoever with respect to this Agreement, the Notes or any Loans made hereunder
(excluding any net  income tax (or franchise tax imposed in lieu of a net income
tax) imposed on the  Bank as a result of a present or former connection or nexus
between the jurisdiction of the government or taxing authority imposing such tax
and the  Bank other than  that arising solely  from the Bank's  having executed,
delivered or performed its obligations or received a payment under, or enforced,
this Agreement, the  Notes or the Collateral Security  Documents), or change the
basis of taxation of payments to the Bank of principal, commitment fee, interest
or any other amount payable hereunder (except for changes in the rate of any tax
presently imposed on the Bank);

            (b)  does or shall  impose, modify or  hold applicable any  reserve,
special  deposit, compulsory loan or similar requirement against assets held by,
or deposits or other liabilities in or for the account of, advances or loans by,
or other credit extended by, or any other acquisition of funds by, any office of
the Bank  which are  not otherwise  included in the  determination of  the LIBOR
Adjusted Rate, the LIBOR Market Index Rate or any fixed rate hereunder; or

            (c)  does or shall impose on the Bank any other condition, 

and if the result of any of the foregoing is to increase the cost to the Bank of
making, renewing or maintaining advances or extensions of credit to the Borrower
or to  reduce any amount receivable  from the Borrower thereunder,  then, in any
such case, the Borrower  shall promptly pay  to the Bank,  upon its demand,  any
additional amounts necessary  to compensate the Bank for such additional cost or
reduced amount receivable which the  Bank deems to be material as  determined by
the Bank with respect  to this Agreement, the Notes or the Loans made hereunder.
If the  Bank becomes entitled to  claim any additional amounts  pursuant to this
Section  2.11, it shall promptly  notify the Borrower of the  event by reason of
which it has become so entitled.  A certificate setting forth calculations as to
any additional amounts payable  pursuant to the foregoing sentence  submitted by
the Bank  to the Borrower  shall be  conclusive in the  absence of  demonstrated
error.

     2.12   CAPITAL  ADEQUACY.   If  the Bank  shall  have determined  that  the
adoption  after  the date  hereof  of  any applicable  law,  rule or  regulation
regarding capital adequacy, or any change  therein after the date hereof, or any
change after the date hereof in the  interpretation or administration thereof by
any governmental authority, central  bank or comparable agency charged  with the
interpretation or administration  thereof, or  compliance by the  Bank with  any
request or directive after  the date hereof regarding capital  adequacy (whether
or not  having  the  force of  law)  of  any  such authority,  central  bank  or
comparable agency, has or  would have the effect of reducing  the rate of return
on  the Bank's capital as a consequence of  its obligations hereunder to a level
below that which the Bank could  have achieved but for such adoption, change  or
compliance (taking  into  consideration  the  Bank's policies  with  respect  to
capital adequacy) by an amount deemed by the Bank to be material, then from time
to time, within 15 days after demand by the  Bank, the Borrower shall pay to the
Bank such  additional amount  or amounts  as will compensate  the Bank  for such
reduction.  The Bank will  promptly notify the Borrower in writing of  any event
of  which it has knowledge, occurring after  the date hereof, which will entitle
the Bank to  compensation pursuant to this Section  2.12 and such notice  of the
amount  due pursuant to this Section 2.12  shall be conclusive in the absence of
demonstrated  error.   In the  event the  Bank requests  additional compensation
pursuant to this Section 2.12, the  Borrower, upon one (1) Business Day's notice
to the Bank  of its intent to do  so, may prepay all, but not  less than all, of
its obligations under Term Loan A, which prepayment shall not be  subject to the
prepayment  penalty  required  pursuant  to  Section  2.4(a)  hereof;  provided,
however, that in the event the Borrower provides such notice to the Bank  of its
intent to prepay Term Loan A, the Bank may, upon notice to the Borrower, rescind
its  demand  for  such  additional  compensation.    Upon  such  rescission  the
above-referenced  prepayment  penalty  shall  be applicable  to  all  subsequent
prepayments  specified  in Section  2.4(a) hereof,  other than  such prepayments
proposed  to  be  made  as  a  result of  a  subsequent  demand  for  additional
compensation hereunder.

     2.13   INABILITY TO DETERMINE LIBOR  BASE RATE OR LIBOR MARKET  INDEX RATE.
In  the event,  and  on  each occasion,  that  prior to  the  first  day of  the
commencement of any Interest Period for a LIBOR Loan and prior  to the first day
of  any month  for a LIBOR  Market Index  Loan, the  Bank shall  have determined
(which determination shall  be conclusive  and binding upon  the Borrower)  that
dollar deposits in the principal amount of such LIBOR Loan or LIBOR Market Index
Loan, as applicable, are not generally available in the London Interbank Market,
or  that the  rate at  which such  dollar deposits  are being  offered  will not
adequately and fairly reflect the cost to the Bank of  making or maintaining the
principal amount  of such LIBOR  Loan and/or  LIBOR Market Index  Loan, or  that
reasonable  means do  not exist for  ascertaining the  LIBOR Base  Rate or LIBOR
Market Index  Rate, the  Bank shall,  as  soon as  practicable thereafter,  give
written, telegraphic or telephonic notice of such determination to the Borrower.
After such notice shall have been given and until the  circumstances giving rise
to such notice no longer  exist, each request for  a LIBOR Loan or LIBOR  Market
Index Loan, or for conversion to or maintenance of a LIBOR Loan or  LIBOR Market
Index Loan pursuant to the terms of this Agreement,  shall be deemed to be for a
Base  Rate Loan.  Each determination by  the Bank hereunder  shall be conclusive
absent error in calculation.

     2.14   INDEMNITY.   The Borrower  agrees to indemnify the  Bank and to hold
the Bank harmless from any loss, cost, or expense  which the Bank may sustain or
incur  as a  consequence  of: (a)  default by  the  Borrower in  payment of  the
principal  of  or  interest on  any  LIBOR  Loan  or  LIBOR Market  Index  Loan,
including,  without  limitation,  any  loss,   cost,  or  expense  arising  from
additional interest or fees  payable by the Bank to lenders of funds obtained by
it in order to maintain any LIBOR Loan or LIBOR Market Index Loan hereunder, (b)
default by the Borrower in making a borrowing of a LIBOR Loan after the Borrower
has given a  notice of borrowing in  accordance with Section 2.6  hereof; or (c)
default  by the  Borrower in making  any prepayment  of a  LIBOR Loan  after the
Borrower has given  a notice thereof.  This covenant shall survive for two years
following the termination of this Agreement and payment of the Notes.

                                    SECTION 3
                                LETTERS OF CREDIT

     3.1    AVAILABILITY OF CREDITS.

            (a)  Terms of Letters of Credit. Subject to the terms and conditions
set forth herein, the Bank shall from time to time prior to the Revolving Credit
Termination Date  issue Letters of Credit  for the account of  the Borrower (and
for the  benefit of the Borrower or any of  the Domestic Group) on the following
terms and conditions:

                 (i)    at the time  of issuance  of the Letter  of Credit,  the
face amount of such Letter of Credit  aggregated with (A) the face amount of all
other  Letters  of  Credit  then  outstanding  hereunder  and  (B)  all  amounts
outstanding  under the  Revolving  Credit  Facility  shall  not  exceed  in  the
aggregate the Revolving Credit Commitment;

                 (ii)   the  final expiry date of each Letter of Credit shall be
on or before the Revolving Credit Termination Date;

                 (iii)  there shall not  exist at  the time  of issuance  of the
Letter of Credit, and as a result thereof, any Event of Default or Default;

                 (iv)   the Borrower  shall have completed and  delivered to the
Bank (A) the  Advance Request Form  and (B) a Letter  of Credit Application,  as
provided in Section 3.2 hereof;

                 (v)    each Letter of Credit issued  under this Section 3 shall
be required by the Borrower  (and for the benefit of the Borrower or  any of the
Domestic Group) in the ordinary course of its respective business; and

                 (vi)   the  Borrower shall have paid  any and all  LC Fees then
outstanding or due in connection with such issuance.

            (b)  Existing Letters  of Credit. The parties  acknowledge and agree
that the  Existing Letters of Credit are  deemed to be Letters  of Credit issued
under and subject to the provisions of this Agreement and this Section 3.

            (c)  Extension of  Letters of Credit. Notwithstanding the provisions
of this  Section 3.1  requiring that  the final  expiry date  of each Letter  of
Credit  be on  or before  the Revolving  Credit Termination  Date, the  Bank may
issue,  upon the Borrower's  request if  required by  a proposed  beneficiary, a
Letter of Credit which by its terms  may be extended beyond the Revolving Credit
Termination  Date. With respect to  any such Letter  of Credit issued hereunder,
the Borrower  hereby agrees that it  will deliver on  or before the  issuance of
such Letter of Credit cash collateral in an amount  equal to one hundred percent
(100%) of the outstanding undrawn amount  of each such Letter of Credit pursuant
to Section 3.4(d) hereof.

     3.2    APPROVAL  AND ISSUANCE. The Borrower  shall provide to  the Bank not
less than five (5) Business  Days' prior written notice of each  request for the
issuance  of a Letter  of Credit by  delivery of an  Advance Request Form  and a
Letter of  Credit Application  in the  form attached hereto  as Exhibit  C. Each
Advance  Request  Form submitted  by  the Borrower  to  the Bank  requesting the
issuance of a Letter of Credit shall (a) be certified by the chief  executive or
chief financial officer  or controller of the Borrower, (b)  list all Letters of
Credit outstanding as of such date and, for each Letter of Credit so listed, its
face  amount, outstanding undrawn balance and expiration date, and (c) represent
as to the matters set forth in Section 2.6(a)(i), (ii) and (iii) hereof.

     3.3    OBLIGATIONS OF THE BORROWER.

            (a)  The Borrower agrees to pay to  the Bank in connection with each
Letter of Credit issued hereunder: (i) immediately upon the demand  of the Bank,
the  amount paid  by  the Bank  with  respect to  such  Letter of  Credit,  (ii)
immediately upon  demand  of  the  Bank,  the  amount  of  any  draft  presented
purporting to be drawn under such Letter  of Credit provided that the draft  and
accompanying documents conform to the terms  of the Letter of Credit but subject
to the  terms of Section 3.5  hereof (whether or not  the Bank has  at such time
honored  such draft) and any other  amounts paid thereunder (it being understood
that the Bank is  not required to make demand upon or  proceed against any other
party  or to  resort  to  any  Collateral  before  obtaining  payment  from  the
Borrower); (iii) upon the issuance of each Letter of Credit and, with respect to
each renewal thereof, pro rata on the basis of the length of the renewal period,
a fee to the Bank equal to one percent (1%) per annum on the face amount of each
standby Letter  of Credit,  and  upon demand  by the  Bank,  all other  standard
issuance,  negotiation  and other  fees and  commissions  at the  standard rates
charged from  time to time by the Bank to its customers generally (collectively,
the "LC FEES");  and (iv) interest on any Indebtedness  outstanding with respect
to such Letter  of Credit, whether for  funds paid on  drafts on such Letter  of
Credit, or otherwise (but  such Indebtedness shall not include  undrawn balances
of such Letter  of Credit issued hereunder)  calculated at the rate  and paid at
the  times and  in the  manner  set forth  for the  calculation  and payment  of
interest in Section 2.5 hereof. Interest under clause (iv) above shall accrue on
amounts paid  on a Letter of  Credit (if not  reimbursed by the Borrower  on the
same day) from  the date of payment by the Bank,  whether or not demand is made,
until such  amounts are reimbursed by  the Borrower whether before,  at or after
demand.

            (b)  In the absence of an Event of Default or Default hereunder, and
subject  to the provisions of this Agreement,  the Bank hereby agrees to advance
funds to the  Borrower under the Revolving Credit Facility  to make the payments
required under Sections  3.3(a)(i) and (ii) hereof with  respect to amounts paid
or  payable on account of a draft drawn under a Letter of Credit. The Borrower's
obligation to reimburse  the Bank for such advance shall  be deemed an "Advance"
under Section 2 of this Agreement; and such Advance shall bear interest from the
date of such  Advance (without  duplication of interest  accrued under  Sections
3.3(a)(iv) and 3.3(c)  hereof), be repayable, prepayable,  and otherwise subject
to all the  terms and conditions hereof  as if advanced by the  Bank pursuant to
Section 2.6 hereof.
            (c)  If any payment by the Bank  of a draft drawn under a Letter  of
Credit  is  not advanced  pursuant  to  Section  3.3(b) hereof  because  of  the
occurrence or continuation of an Event of Default hereunder and is not otherwise
reimbursed by the Borrower prior to  or on the date of such payment,  the amount
of such payment  shall thereupon be deemed for purposes  hereof a "Reimbursement
Obligation"  hereunder. Such Reimbursement Obligation shall bear interest at the
default  rate set  forth  in  Section  2.5(d) hereof  with  respect  to  amounts
outstanding under the Revolving Credit Facility (without duplication of interest
accrued  under Sections 3.3(a)(iv) and  3.3(b) hereof), shall  be repayable upon
demand.    Notwithstanding the  foregoing,  the creation  of  such Reimbursement
Obligation shall not in any way limit the Bank's ability to treat as an Event of
Default hereunder the Borrower's failure to make such reimbursement.

     3.4    COLLATERAL SECURITY.

            (a)  The indebtedness, liabilities  and obligations of the  Borrower
under this  Section  3, however  created or  incurred, whether  now existing  or
hereafter arising,  due or  to  become due,  absolute or  contingent, direct  or
indirect,  secured  or  unsecured, are  among  the  obligations  secured by  the
security  interests, liens  and  encumbrances created  by  the Selas  Collateral
Security Documents  which the Borrower has delivered to the  Bank, as well as by
the other Collateral Security Documents, and the Bank is entitled to the benefit
of the collateral security granted thereunder with respect to such indebtedness.

            (b)  Notwithstanding  the  payment in  full  of  the  Loan,  or  the
occurrence of Revolving  Credit Termination Date, the  Collateral shall continue
to  secure the indebtedness, liabilities  and obligations of  the Borrower under
this Section 3, until  all Letters of Credit  shall have expired and  payment in
full of all indebtedness, liabilities and obligations under this Section 3 shall
have occurred, except as provided in subsection (c) below.

            (c)  If  the  Borrower  shall  have  deposited  with  the Bank  cash
collateral (in the  form of First  Union National  Bank certificates of  deposit
("FUNB CDS"))  or U.S. Treasury  securities with maturities no  more than ninety
(90) days  from  the date  of  deposit ("U.S.  TREASURY  BILLS") (discounted  in
accordance with customary banking practice to present value to determine amount)
in an amount equal at all times to one hundred percent (100%) of the outstanding
undrawn amount  of all Letters  of Credit (all  interest on such  deposited cash
collateral and U.S.  Treasury Bills also  to be held  by the Bank as  additional
cash collateral) on  or before the  Revolving Credit Termination Date  and shall
have  irrevocably paid in full the Loans and all other indebtedness, liabilities
and obligations  of the Borrower to the Bank under this Agreement (including all
indebtedness and fees due and  owing under this Section 3 other than for undrawn
balances of  Letters of Credit  and other fees  and liabilities not  yet accrued
thereunder), the Borrower shall be entitled to the release of the Collateral and
the termination of all  covenants of the  Borrower under this Agreement  (except
under this Section 3).

            (d)  On the Revolving Credit  Termination Date or the  occurrence of
an  Event of  Default, the  Bank may require  (and in  the case  of an  Event of
Default  occurring under Section 9.1(h) it shall be required automatically) that
the Borrower deliver to the Bank, unless previously delivered to  the Bank under
subsection (c) above, cash (to be  invested in FUNB Cds) or U.S. Treasury  Bills
with maturities of not more  than 90 days from the date  of delivery (discounted
in  accordance with  customary banking  practice to  present value  to determine
amount) in  an amount equal at  all times to  one hundred percent (100%)  of the
outstanding undrawn  amount of all Letters of Credit, such cash or U.S. Treasury
Bills and all interest earned thereon to constitute cash collateral for all such
Letters of Credit. At  such time as such cash collateral  or U.S. Treasury Bills
is  required to be  and has not  been deposited,  the Bank shall  be entitled to
liquidate such of  the other Collateral  as is necessary  or appropriate in  its
sole judgment so as to create such cash collateral.

            (e)  Any  cash collateral  deposited under  subsections (c)  and (d)
above  shall be held by the Bank, and invested and reinvested at the expense and
the written direction of the Borrower, in U.S. Treasury Bills with maturities of
no more than thirty  (30) days from the  date of investment. Interest  earned on
such collateral shall be distributed to the Borrower quarterly.

     3.5    GENERAL  TERMS OF CREDITS. The following  terms and conditions apply
with respect to each Letter  of Credit (a "CREDIT") notwithstanding anything  to
the contrary contained herein:

            (a)  The Borrower assumes  all risks of the acts or omissions of the
beneficiary of each Credit with respect to the use of the Credit or with respect
to the  beneficiary's obligations to the  Borrower. Neither the Bank  nor any of
its officers or directors shall be liable  or responsible for: (i) the use which
may be made  of the Credit or  for any acts or  omissions of the beneficiary  in
connection  therewith)  (ii)  the  accuracy,  truth,  validity,  sufficiency  or
genuineness of documents, or  of any endorsement thereon, even if such documents
should in fact prove to be in any or all respects false, misleading, inaccurate,
invalid,  insufficient,  fraudulent or  forged; (iii)  the  payment by  the Bank
against  presentation   of  facially   conforming  documents;  (iv)   any  other
circumstances whatsoever  in making or  failing to make  payment under a  Credit
provided the Bank acts in good faith   and without gross negligence with respect
thereto; or (v) any inaccuracy, interruption,  error or delay in transmission or
delivery  of correspondence  or documents  by post,  telegraph or  otherwise. In
furtherance and not in limitation of the foregoing, the Bank may accept facially
conforming  documents   without   responsibility  for   further   investigation,
regardless of any notice or information to the contrary.

            (b)  To the extent any failure to comply with the provisions of this
Section 3.5(b)  could,  either individually  or in  the aggregate,  result in  a
material adverse  change in  the financial  condition,  business, operations  or
prospects of the Borrower and its Consolidated Subsidiaries, the Borrower agrees
to procure or to cause the beneficiaries of each Credit  to procure promptly any
necessary  import and  export or  other  licenses for  the import  or export  or
shipping of any goods referred to in or  pursuant to a Credit and to comply  and
to cause the beneficiaries to comply with all foreign  and domestic governmental
regulations with  respect  to the  shipment  and warehousing  of  such goods  or
otherwise  relating   to  or  affecting  such   Credit,  including  governmental
regulations pertaining to transactions involving designated foreign countries or
their nationals,  and to furnish such  certificates in that respect  as the Bank
may at any time reasonably require, and to keep such goods adequately covered by
insurance in amounts,  with carriers and for such risks as shall be customary in
the industry and to cause  the Bank's interest to be endorsed  on such insurance
and to  furnish the Bank at its request with reasonable evidence thereof. Should
such  insurance (or  lack  thereof)  upon  said  goods for  any  reason  not  be
reasonably satisfactory  to the  Bank, the  Bank may (but  is not  obligated to)
obtain, at the Borrower's expense, insurance satisfactory to the Bank.

            (c)  In  connection  with  each Credit,  neither  the  Bank  nor any
correspondent  shall be responsible for: (i) any  breach of contract between the
Credit beneficiaries and the  Borrower; (ii) any laws, customs,  and regulations
which may be effective in any jurisdiction where  any negotiation and/or payment
of such Credit occurs; (iii) failure of documents (other than documents required
by  the terms  of the Credit)  to accompany  any draft  at negotiation;  or (iv)
failure of any entity to note the amount of any document or draft on the reverse
of such Credit or to surrender or to take up such Credit or to forward documents
other than documents  required by the  terms of the  Credit. In connection  with
each Credit, the Bank shall not be responsible for any error, neglect or default
of any  correspondent. None of  the above  shall affect, impair  or prevent  the
vesting  of the  Bank's rights or  powers hereunder.  If a  Credit provides that
payment is  to be made  by the Bank's correspondent,  neither the Bank  nor such
correspondent  shall be  responsible for  the failure  of any  of the  documents
specified in  such Credit to  come into the  Bank's hands, or  for any  delay in
connection therewith, and the Borrower's  obligation to make reimbursement shall
not be affected by such failure or delay in the receipt of any such documents.

            (d)  Notwithstanding the foregoing, with  respect to any Credit, the
Borrower shall  have a claim against the  Bank, and the Bank  shall be liable to
the Borrower, to the extent,  but only to the extent, of any  direct, as opposed
to indirect or consequential, damages suffered by the Borrower caused by (i) the
Bank's willful misconduct or  gross negligence and; (ii)  the Bank's failure  to
make payments  under a presentation under  a Credit that strictly  complies with
the terms of the Credit in all respects.

            To  the extent  not inconsistent  with this  Agreement, the  Uniform
Customs  and Practices  for Documentary  Credits (1993  Revision), International
Chamber of Commerce Publication No. 500 are hereby made a part of this Agreement
with respect to obligations in connection with each Credit.

                                    SECTION 4

there are no actions, suits, proceedings or claims which are  pending or, to the

Material Adverse Effect.

Subsidiaries  has good and marketable title to all of its real property and good

the absence of  notes) and discloses all  liabilities, as of such  dates, of the
Borrower and its Consolidated Subsidiaries in each case which are required to be
disclosed  under GAAP,  and there  has been  no material  adverse change  in the
financial  condition   or  business  of   the  Borrower  and   its  Consolidated
Subsidiaries from the date of the latest of such statements to the date  hereof;
and

            (b)  All financial  statements and other documents  furnished by the
Borrower to  the Bank  in connection  with this  Agreement do  not and  will not
contain any  untrue statement of material fact or omit  to state a material fact
necessary in order to make the statements contained therein not misleading.  The
Borrower has disclosed in reasonable detail  to the Bank in writing any  and all
events  which have occurred  and could reasonably be  expected to materially and
adversely affect the business, properties, operations or condition, financial or
otherwise,  of the Borrower and  its Consolidated Subsidiaries,  considered as a
whole,  or  the  Borrower's  ability  to  perform  its  obligations  under  this
Agreement,  and  all other  documents, agreements  and  actions required  by the

filing thereof,  and has  paid all  applicable federal,  state and local  taxes,
other  than taxes not  yet due or  which may be  paid hereafter without penalty;
provided  that no  such taxes  shall be required  to be  paid if  they are being
contested   in  good  faith  by  appropriate  proceedings  and  are  covered  by
appropriate  reserves maintained in cash  or cash equivalents  and in accordance
with GAAP  and (b) the Borrower and  each of the Guarantors  has no knowledge of
any deficiency or additional assessment in connection therewith not provided for
in the financial statements required hereunder or otherwise disclosed in writing
to the Bank.

     4.10   FUNDED DEBT. The Borrower  has no presently outstanding  Funded Debt
or similar  obligations including  contingent obligations and  obligations under
leases of property from others, except the Funded Debt and obligations described

to the Bank from time to time pursuant to Sections 4.8(a), 6.2 and 6.3 hereof.

     4.11   INVESTMENTS.  As of the date of this Agreement, except  as set forth

or investments  in or loans to any other individuals or business entities, other

pursuant to Sections 4.8(a), 6.2 and 6.3 hereof:

            (a)  The Borrower and each  ERISA Affiliate is in compliance  in all
material  respects with all applicable  provisions of ERISA  and the regulations
promulgated thereunder;

            (b)  Neither  the  Borrower nor  any  ERISA  Affiliate maintains  or
contributes to or has  maintained or contributed  to any multiemployer plan  (as
defined in section 4001 of ERISA);

            (c)  Neither  the  Borrower  nor  any ERISA  Affiliate  sponsors  or
maintains  any  Plan under  which there  is  an Accumulated  Funding Deficiency,
whether or not waived;

            (d)  The excess of the aggregate liability  for accrued benefits and
other ancillary benefits under each defined benefit pension Plan that is or will
be sponsored or maintained  by the Borrower, or any ERISA  Affiliate (determined
on the basis of the actuarial assumptions prescribed for  valuing benefits under
terminating  single-employer defined benefit plans under Title IV of ERISA) over
the aggregate fair market value  of the assets under  each such defined Plan  is
not likely to have a Material Adverse Effect;

            (e)  The  aggregate   liability  of  the  Borrower   and  the  ERISA
Affiliates arising out of  or relating to a failure  of any Plan to  comply with
the provisions of ERISA or the Code, will not have a Material Adverse Effect;

            (f)  There exists  no unrecorded liability (determined  on the basis
of actuarial assumptions  utilized by the actuary for the  Plan in preparing the
most  recent Annual Report)  of the Borrower,  or any ERISA  Affiliate under any
Plan, program  or arrangement providing post-retirement life  or health benefits
that is likely to have a Material Adverse Effect;

case in connection with the Borrower's obtaining the Loans from the Bank, except

at  any time  has  it been  engaged  principally, or  as  one of  its  important
activities,  in the  business  of extending  or arranging  for the  extension of
credit,  for the purpose  of purchasing or  carrying any margin  stock or margin
securities; nor  will the proceeds of the Loan be used by the Borrower, directly
or indirectly, for such purposes.

     4.15   PERFECTION  OF SECURITY INTERESTS.   Except as otherwise provided in
this Agreement, no action, including any filing or recording of any document, is
necessary  in order to establish, perfect and maintain the Bank's first priority
security  interests (to  the extent  that  a security  interest  therein may  be
perfected by the  filing of financing statements) in such  assets created by the
Collateral  Security Documents (subject to no prior liens and encumbrances other
than  those permitted pursuant  to Section 7.4  hereof) except for  the periodic
filing of  continuation statements  with respect  to financing  statements filed
under the Uniform Commercial  Code of applicable jurisdiction and, to the extent
applicable  to  any Collateral,  any filings  with  the United  States Copyright
Office or the United States Patent and Trademark Office and any action or filing
in compliance with the Federal Assignment of Claims Act.

     4.16   PERFECTION OF MORTGAGE LIEN.   Except as otherwise provided  in this
Agreement, no  action, including  the filing  or recording  of any  document, is
necessary  to  establish,  perfect and/or  maintain  the  Bank's  first priority
perfected lien in the Dresher Real Property or the Ohio Real Property.

     4.17   PERFECTION  OF PLEDGE.  No action, including any filing or recording
of any document, is necessary  under present law in order to  establish, perfect
and/or maintain the  first priority security interest in all  of the outstanding
shares of  capital stock of Deuer, RTI, RTI  Electronics and RTIE created by the
Selas Pledge Agreement.

     4.18   HAZARDOUS  SUBSTANCES. Except  as disclosed  on Schedule  X attached
hereto:

            (a)  The Borrower and each of its Consolidated Subsidiaries: (i) has
received  all permits  and filed  all  notifications necessary  to carry  on its
respective business (other than  permits and notifications the absence  of which
is  not reasonably  likely, either singly  or in  the aggregate, to  result in a
Material Adverse Effect);  and (ii) is in  compliance in all respects with   all
Environmental  Control Statutes  other  than any  failure  to comply  with  such
Environmental Control Statutes which  failure is  not reasonably  likely, either
singly or in the aggregate, to result in a Material Adverse Effect.

            (b)  The  Borrower and  each  of its  Consolidated Subsidiaries  has
given no written or oral notice, nor has it failed to give any  required notice,
to  EPA or  any state or  local agency with  regard to any  actual or imminently
threatened  Release  of Hazardous  Substances  on  properties owned,  leased  or
operated  by  the  Borrower  or  used in  connection  with  the  conduct  of its
respective business  and operations, which Release is  reasonably likely, either
singly or in the aggregate, to result in a Material Adverse Effect.

            (c)  Neither the  Borrower nor any of  its Consolidated Subsidiaries
has received notice that it is  potentially responsible for costs of clean-up or
remediation  of  any  actual  or  imminently  threatened  Release  of  Hazardous
Substances pursuant to any  Environmental Control Statute, which costs  of clean
up are  reasonably likely, either  singly or  in the aggregate,  to result in  a
Material Adverse Effect.

     4.19   SOLVENCY.  To the best knowledge  of the Borrower,  the Borrower and
each of its Consolidated Subsidiaries is solvent such that (i) the fair value of
its assets (including without limitation the  fair salable value of the goodwill
and other  intangible  property of  the Borrower  and each  of its  Consolidated
Subsidiaries) is greater  than the  total amount of  its liabilities,  including
without limitation, contingent  liabilities, (ii) the present fair salable value
of  its assets  (including without  limitation  the fair  salable  value of  the
goodwill  and  other  Intangible  Assets  of   the  Borrower  and  each  of  its
Consolidated Subsidiaries) is not less than the amount that will  be required to
pay the probable  liability on its respective debts as  they become absolute and
matured, (iii) it is able to realize upon its assets and pay its debts and other
liabilities,  contingent obligations and other commitments as they mature in the
normal course  of business.  Neither the  Borrower nor  any of its  Consolidated
Subsidiaries intends  to, or believes that  it will, incur debts  or liabilities
beyond  its ability  to pay  as such  debts and  liabilities mature, nor  is the
Borrower  or  any of  its  Consolidated Subsidiaries  engaged  in a  business or
transaction, or  about to engage  in a  business or transaction,  for which  its
property  would   constitute  unreasonably   small  capital  after   giving  due
consideration to  the prevailing practice and  industry in which it  is engaged.
For  purposes of  this  Section 4.19,  in  computing  the amount  of  contingent
liabilities at any  time, it is intended that such  liabilities will be computed
at the  amount which, in  light of all  the facts and  circumstances existing at
such time,  represents the amount that  reasonably can be expected  to become an
actual matured liability.

     4.20   FOREIGN  ASSETS CONTROL  REGULATIONS. Neither  the borrowing  by the
Borrower nor its use of the proceeds of the Loan will violate the Foreign Assets
Control  Regulations, the  Foreign Funds  Control Regulations,  the Transactions
Control Regulations, the  Cuban Assets Control  Regulations, the Iranian  Assets
Control Regulation, or  the Libyan  Sanctions Regulations of  the United  States
Treasury Department (31 C.F.R. Subtitle B, Chapter V, as amended).

     4.21   INVESTMENT COMPANY  ACT. After review of  all applicable shareholder
records and  all filings under section13  of the Securities and  Exchange Act of
1934, the Borrower  is not, directly  or indirectly controlled  by or acting  on
behalf of any entity which  is an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

     4.22   PUBLIC  UTILITY HOLDING  COMPANY  ACT. The  execution, delivery  and
performance of this Agreement,  the Notes and the Collateral  Security Documents
do not require  any filing, authorization  or consent  under the Public  Utility
Holding Company Act of 1935, as amended (the "1935 Act").


                                    SECTION 5

its  Consolidated Subsidiaries or its respective property and such process shall
not  be paid, waived, stayed,  vacated, discharged, settled,  satisfied or fully
bonded within sixty (60) days after its issuance or levy.

     9.2    REMEDIES. Upon the happening of any Event of Default and at any time
thereafter, at the election of the Bank, with notice to the Borrower (except  if
an  Event of  Default described  in  Section 9.1(h)  shall occur  in which  case
acceleration shall occur automatically without notice), the Bank may declare the
entire  unpaid balance, principal, interest and fees, of all Indebtedness of the
Borrower to the Bank, hereunder or otherwise, to be immediately due and payable.
Upon such declaration (and, upon the occurrence of an Event of Default described
in Section 9.1(h)  hereof, without such declaration  or other notice), the  Bank
shall have no further obligation  to make any Advances  or issue any Letters  of
Credit under the Revolving Credit Facility and the immediate right to enforce or
realize  on any  Collateral in any  manner or  order it  deems expedient without
regard  to any equitable principles of marshalling  or otherwise. In addition to
any  rights  granted  hereunder or  in  any  documents  delivered in  connection
herewith,  the  Bank shall  have  all the  rights  and remedies  granted  by any
applicable law, all of which shall be cumulative in nature.



                                   SECTION 10
                                  MISCELLANEOUS

     10.1   INDEMNIFICATION AND RELEASE  PROVISIONS. The Borrower  hereby agrees
to defend the Bank  and its directors, officers,  agents, employees and  counsel
from, and  hold each of them  harmless against, any and  all losses, liabilities
(including  without limitation  settlement  costs and  amounts, transfer  taxes,
documentary  taxes,  or  assessments   or  charges  made  by   any  governmental
authority), claims, damages, interest,  judgments, costs, or expenses, including
without limitation fees  and disbursements of counsel,  incurred by any  of them
arising out of
or in connection with or  by reason of this Agreement, the making  of the Loans,
the  issuance of  any  letter of  credit, or  any Collateral  Security Document,
including without limitation, any and all losses, liabilities, claims,  damages,
interests,  judgments,  costs  or expenses  relating  to  or  arising under  any
Environmental Control  Statute or  the application  of any  such Statute to  the
Borrower's or any  of its  Consolidated Subsidiaries'  respective properties  or
assets. The Borrower hereby releases, and shall cause each Guarantor to release,
the Bank and its directors, officers, agents, employees and counsel from any and
all  claims for loss, damages, costs or expenses  caused or alleged to be caused
by any act or omission on  the part of either of them. All  obligations provided
for in this Section 10.1 shall survive any termination of this Agreement and the
repayment of the Loan.

     10.2   PARTICIPATIONS AND ASSIGNMENTS. The Borrower hereby acknowledges and
agrees that the  Bank may at any  time: (a) grant  participations in all or  any
portion of the Loans or any Note or of its right, title and interest  therein or
in  or to this Agreement  (collectively, "PARTICIPATIONS") to  any other lending
office  or to any other bank, lending  institution or other entity which has the
requisite  sophistication to  evaluate the  merits and  risks of  investments in
Participations  ("PARTICIPANTS");  provided,  however,  that:  (i)  all  amounts
payable by  the Borrower hereunder  shall be determined as  if the Bank  had not
granted such Participations;  and (ii) any agreement pursuant to  which the Bank
may grant a Participation: (x) shall provide that the Bank shall retain the sole
right  and responsibility to enforce  the obligations of  the Borrower hereunder
including, without limitation, the right  to approve any amendment, modification
or waiver of any  provisions of this Agreement; (y) such participation agreement
may  provide that  the Bank  will not  agree to  any modification,  amendment or
waiver  of  this  Agreement  without the  consent  of  the  Participant  if such
modification, amendment  or waiver  would  reduce the  principal of  or rate  of
interest on the Loans or postpone the date fixed for any payment of principal of
or interest  on  the  Loans;  and  (z) shall  not  relieve  the  Bank  from  its
obligations,  which shall remain absolute,  to make Advances  hereunder; and (b)
assign,  in one or more  transactions, up to an aggregate  amount equal to forty
percent (40%) of its rights under the Loans with notice to Borrower.

     10.3   BINDING AND GOVERNING LAW. This Agreement and all documents executed
hereunder shall be binding  upon and shall inure  to the benefit of  the parties
hereto  and their respective successors and assigns  and shall be governed as to
their  validity, interpretation and  effect by the  laws of  the Commonwealth of
Pennsylvania.

     10.4   SURVIVAL. All agreements,  representations, warranties and covenants
of  the Borrower  contained herein  or in  any documentation  required hereunder
shall  survive  the execution  of  this Agreement  and  the making  of  the Loan
hereunder  and, except for Sections 6.10  and 10.1 which provide otherwise, will
continue in full force and effect as long as any Indebtedness of the Borrower to
the Bank remains outstanding.

     10.5   NO WAIVER; DELAY. If the Bank shall waive any power, right or remedy
arising  hereunder or under any applicable law,  such waiver shall not be deemed
to be a waiver upon any later occurrence or recurrence of any of said events. No
delay by the Bank in the exercise of any power, right or remedy shall, under any
circumstances, constitute  or be deemed to  be a waiver, express  or implied, of
the same  and no course of dealing between the parties hereto shall constitute a
waiver of the  Bank's powers, rights or  remedies. The remedies herein  provided
are cumulative and not exclusive of any remedies provided by law.

     10.6   MODIFICATION;   WAIVER.  Except   as  otherwise  provided   in  this
Agreement,  no modification or amendment hereof, or waiver or consent hereunder,
shall be  effective unless made in  a writing signed by  appropriate officers of
the parties hereto.

     10.7   HEADINGS. The  various headings in  this Agreement are  inserted for
convenience  only and  shall not  affect the  meaning or interpretation  of this
Agreement or any provision hereof.

     10.8   NOTICES.  Any notice, request  or consent  required hereunder  or in
connection  herewith  shall  be  deemed  satisfactorily  given  if  in   writing
