PROSPECTUS      
                        UNITED STATES FILTER CORPORATION

                                  $140,000,000
                   6% Convertible Subordinated Notes Due 2005
                                      and
                             Shares of Common Stock
                        Issuable Upon Conversion Thereof


   This Prospectus covers the resale from time to time by the holders (the
"Selling Securityholders") of up to $140,000,000 aggregate principal amount of
6% Convertible Subordinated Notes due 2005 (the "Notes") of United States Filter
Corporation (the "Company").  This Prospectus also covers sales by the Selling
Securityholders from time to time of shares of common stock, $.01 par value (the
"Common Stock"), of the Company into which the Notes are convertible (the
"Conversion Shares").

   The Notes are convertible at the option of the holder into shares of Common
Stock of the Company, at any time at or prior to maturity, unless previously
redeemed, at a conversion price of $27.50 per share (equivalent to a conversion
rate of 36.36 shares per $1,000 principal amount of Notes), subject to
adjustment in certain events.  Interest on the Notes is payable semi-annually on
March 15 and September 15 of each year, commencing on March 15, 1996.

   The Notes are redeemable, in whole or in part, at the option of the Company,
at any time on or after September 23, 1998, at the redemption prices set forth
herein, plus accrued and unpaid interest to the date of redemption.  The Company
is required to offer to purchase the Notes upon a Change of Control (as
defined), at 101% of the principal amount thereof, plus accrued and unpaid
interest to the date of purchase.

   The Notes are unsecured general obligations of the Company, subordinated in
right of payment to all existing and future Senior Indebtedness of the Company,
and are structurally subordinated to all liabilities (including trade payables)
of the Company's subsidiaries. The Indenture does not restrict the incurrence of
Senior Indebtedness or other indebtedness by the Company or its subsidiaries. At
September 30, 1995 the Company had approximately $14,573,000 of Senior
Indebtedness, and the Company's subsidiaries had approximately $119,822,000 of
trade payables and accrued liabilities. See "Description of Notes."    

   The Notes were issued by the Company on September 18, 1995 in a private
placement and were resold by the initial purchaser thereof to qualified
institutional buyers or other accredited institutional investors in transactions
exempt from registration under the Securities Act of 1933, as amended (the
"Securities Act"), and in sales outside the United States within the meaning of
Regulation S under the Securities Act.

   The Selling Securityholders may offer Notes or Conversion Shares from time to
time to purchasers directly or through underwriters, dealers or agents.  Such
Notes or Conversion Shares may be sold at market prices prevailing at the time
of sale or at negotiated prices.  Each Selling Securityholder will be
responsible for payment of any and all commission to brokers, which will be
negotiated on an individual basis.

    
   The Notes have been designated for trading in the Private Offerings, Resales
and Trading through Automated Linkages ("PORTAL") Market.  The Common Stock is
listed on the New York Stock Exchange (the "NYSE") under the trading symbol USF.
On November 7, 1995, the last reported sale price of the Common Stock as
reported on the NYSE was $21 7/8 per share. The Conversion Shares have been
listed on the NYSE. For a description of certain federal income tax consequences
to the holders of the Notes, see "Certain Federal Income Tax Consequences."     

   The Company will not receive any of the proceeds from the sale of any Notes 
or Conversion Shares by the Selling Securityholders.  Expenses of preparing and
filing the registration statement to which this Prospectus relates and all post-
effective amendments will be borne by the Company.  See "Plan of Distribution"
for a description of the indemnification arrangements between the Company and
the Selling Securityholders.

   See "Risk Factors" on pages 3 through 6 of the Prospectus for certain
information relevant to this offering.

   THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

      The Company is a leading global provider of industrial and commercial
  water treatment systems and services, with an installed base of more than
  90,000 systems in the United States, Europe, Latin America and the Far East.
  The Company offers a single-source solution to its industrial, commercial and
  municipal customers through what the Company believes to be the industry's
  broadest range of cost-effective water treatment systems, services and proven
  technologies.  The Company capitalizes on its substantial installed base to
  sell additional systems and utilizes its global network of 124 sales and
  service facilities, including 12 manufacturing plants, to provide customers
  with ongoing service and maintenance.  In addition, the Company is a leading
  international provider of service deionization ("SDI") and outsourced water
  services, including operation of water purification and wastewater treatment
  systems at customer sites.

      The Company's principal executive offices are located at 73-710 Fred
  Waring Drive, Suite 222, Palm Desert, California 92260.  The Company's
  telephone number is (619) 340-0098.  References herein to the Company shall
  mean United States Filter Corporation and its subsidiaries, unless the context
  requires otherwise.


                                  RISK FACTORS

      Prospective purchasers should carefully consider the following factors
  relating to the business of the Company and the Notes, together with the
  information and financial data included or incorporated by reference in this
  Prospectus, before purchasing Notes and Conversion Shares offered hereby.

  Acquisition Strategy

      
      In pursuit of its strategic objective of becoming the leading global
  single-source provider of water treatment systems and services the Company
  has, since 1991, acquired and successfully integrated more than 18 domestic
  and international businesses with strong market positions and substantial
  water treatment expertise.  The Company's acquisition strategy entails the
  potential risks inherent in assessing the value, strengths, weaknesses,
  contingent or other liabilities and potential profitability of acquisition
  candidates and in integrating the operations of acquired companies.  Although
  the Company generally has been successful in pursuing these acquisitions,
  there can be no assurance that acquisition opportunities will continue to be
  available, that the Company will have access to the capital required to
  finance potential acquisitions, that the Company will continue to acquire
  businesses or that any business acquired will be integrated successfully or
  prove profitable. The Company has no current plans regarding any material 
  acquisitions.
        

      
  International Transactions      

      
      The Company has made and expects it will continue to make acquisitions and
  to obtain contracts in Europe, Latin America, the Far East and other areas
  outside the United States.  While these activities may provide important
  opportunities for the Company to offer its products and services
  internationally, they also entail the risks associated with conducting
  business internationally, including the risk of currency fluctuations, slower
  payment of invoices and possible social, political and economic 
  instability.      

  Reliance on Key Personnel

      The Company's operations are dependent on the continued efforts of senior
  management, in particular Richard J. Heckmann, its Chairman, Chief Executive
  Officer and President.  Should any of the senior managers be unable to
  continue in their present roles, the Company's prospects could be adversely
  affected.

  Profitability of Fixed Price Contracts

      A significant portion of the Company's revenues are generated under fixed
  price contracts.  To the extent that original cost estimates are inaccurate,
  costs to complete increase, delivery schedules are delayed or progress under a
  contract is otherwise impeded, revenue recognition and profitability from a
  particular contract may be adversely affected.  The Company routinely records
  upward or downward adjustments

                                       3.
<PAGE>
  
  with respect to fixed price contracts due to changes in estimates of costs to
  complete such contracts.  There can be no assurance that future downward
  adjustments will not be material.

  Cyclicality of Capital Equipment Sales

      The sale of capital equipment within the water treatment industry is
  cyclical and influenced by various economic factors including interest rates
  and general fluctuations of the business cycle.  The Company's revenues from
  capital equipment sales were approximately 60% of total revenues for the
  fiscal year ended March 31, 1995 and 48% for the three months ended June 30,
  1995.  While the Company sells capital equipment to customers in diverse
  industries and in domestic and international markets, cyclicality of capital
  equipment sales and instability of general economic conditions could have an
  adverse effect on the Company's revenues and profitability.

  Potential Environmental Risks

      The Company's business and products may be significantly influenced by the
  constantly changing body of environmental laws and regulations, which require
  that certain environmental standards be met and impose liability for the
  failure to comply with such standards.  While the Company endeavors at each of
  its facilities to assure compliance with environmental laws and regulations,
  there can be no assurance that the Company's operations or activities, or
  historical operations by others at the Company's locations, will not result in
  civil or criminal enforcement actions or private actions that could have a
  materially adverse effect on the Company.  In particular, the Company's
  activities as owner and operator of a hazardous waste treatment and recovery
  facility are subject to stringent laws and regulations and compliance reviews.
  Failure of this facility to comply with those regulations could result in
  substantial fines and the suspension or revocation of the facility's hazardous
  waste permit.  In addition, to some extent, the liabilities and risks imposed
  by such environmental laws on the Company's customers may adversely impact
  demand for certain of the Company's products or services or impose greater
  liabilities and risks on the Company, which could also have an adverse effect
  on the Company's competitive or financial position.

  Competition

      The water purification and wastewater treatment industry is fragmented and
  highly competitive.  The Company competes with many domestic and international
  companies in its global markets.  The principal methods of competition in the
  markets in which the Company competes are technology, service, price, product
  specifications, customized design, product knowledge and reputation, ability
  to obtain sufficient performance bonds, timely delivery, the relative ease of
  system operation and maintenance, and the prompt availability of replacement
  parts.  In the municipal contract bid process, pricing and ability to meet bid
  specifications are the primary considerations.  While no competitor is
  considered dominant, there are competitors that are larger and have
  significantly greater resources than the Company, which, among other things,
  could be a competitive disadvantage to the Company in securing certain
  projects.

  Technological and Regulatory Change

      The water purification and wastewater treatment business is characterized
  by changing technology, competitively imposed process standards and regulatory
  requirements, each of which influences the demand for the Company's products
  and services.  Changes in regulatory or industrial requirements may render
  certain of the Company's purification and treatment products and processes
  obsolete.  Acceptance of new products may also be affected by the adoption of
  new government regulations requiring stricter standards.  The Company's
  ability to anticipate changes in technology and regulatory standards and to
  successfully develop and introduce new and enhanced products on a timely basis
  will be a significant factor in the Company's ability to grow and to remain
  competitive.  There can be no assurance that the Company will be able to
  achieve the technological advances that may be necessary for it to remain
  competitive or that certain of its products will not become obsolete.  In
  addition, the Company is subject to the risks generally associated with new
  product introductions and applications, including lack of market acceptance,
  delays in development or failure of products to operate properly.

                                       4.

  Shares Eligible for Future Sale

      The market price of the Company's Common Stock could be adversely affected
  by the availability for sale of shares held on November 1, 1995 by current
  securities holders of the Company, including (i) up to 2,965,829 shares which
  may be delivered by Laidlaw Inc. or its affiliates ("Laidlaw"), at Laidlaw's
  option in lieu of cash, at maturity pursuant to the terms of Exchangeable
  Notes due 2000 of Laidlaw (the "Exchangeable Notes") (the amount of shares or
  cash delivered or paid to be dependent within certain limits upon the value of
  the Company's Common Stock at maturity), which Exchangeable Notes are being
  offered to the public by Laidlaw, (ii) 3,041,092 shares which are being
  offered to the public by a subsidiary of Eastern Enterprises (the "Eastern
  Shares") concurrently with, but not as a condition to, the offering of the
  Exchangeable Notes, (iii) 2,926,829 shares issuable upon conversion of
  convertible debentures of the Company at a conversion price of $20.50 per
  share of Common Stock that are currently registered for sale under the
  Securities Act pursuant to a shelf registration statement, (iv) 2,353,729
  outstanding shares that are covered by three shelf registration statements
  filed under the Securities Act, including 371,229 shares owned by Anjou
  International Company which are subject to an over-allotment option granted to
  the underwriters of the Eastern Shares, (v) 1,320,000 shares issuable upon
  conversion of shares of preferred stock of the Company, which are subject to
  an agreement pursuant to which the holder has certain rights to request the
  Company to register the sale of such holder's Common Stock under the
  Securities Act and, subject to certain conditions, to include certain
  percentages of such shares in other registration statements filed by the
  Company ("Registration Rights"), and (vi) 334,626 outstanding shares subject
  to Registration Rights. In addition, the Company has registered for sale under
  the Securities Act 2,000,000 shares which may be issuable by the Company from
  time to time in connection with acquisitions of businesses or assets from
  third parties.
     


        

  Subordination
     
      The Notes are subordinated in right of payment to all existing and future
  Senior Indebtedness and are structurally subordinated to all liabilities
  (including trade payables) of the Company's subsidiaries.  The Indenture does
  not restrict the incurrence of Senior Indebtedness or other indebtedness by
  the Company or its subsidiaries. At September 30, 1995 the Company had
  approximately $14.6 million of Senior Indebtedness outstanding. By reason of
  such subordination of the Notes, in the event of the insolvency, bankruptcy,
  liquidation, reorganization, dissolution or winding up of the business of the
  Company or upon a default in payment with respect to any indebtedness of the
  Company or an event of default with respect to such indebtedness resulting in
  the acceleration thereof, the assets of the Company will be available to pay
  the amounts due on the Notes only after all Senior Indebtedness has been paid
  in full. The Notes rank pari passu in all respects with other unsecured
  subordinated obligations of the Company, including the Company's 5%
  Convertible Subordinated Debentures due 2000 (as defined). See "Description of
  the Notes-Subordination."    

      The Company conducts its operations through its subsidiaries.
  Accordingly, the Company's ability to meet its cash obligations is dependent
  in part upon the ability of its subsidiaries to make cash distributions to the
  Company.  The ability of its subsidiaries to make distributions to the Company
  is and will continue to be restricted by, among other limitations, applicable
  provisions of the laws of national or state governments and contractual
  provisions.  The Indenture does not limit the ability of the Company's
  subsidiaries to incur such restrictions in the future.  The right of the
  Company to participate in the assets of any subsidiary (and thus the ability
  of holders of the Notes to benefit indirectly from such assets) are generally
  subject to the prior claims of creditors, including trade creditors, of that
  subsidiary except to the extent that the Company is recognized as a creditor
  of such subsidiary, in which case the Company's claims would still be subject
  to any security interest of other creditors of such subsidiary.  The Notes,
  therefore, are structurally subordinated to creditors, including trade
  creditors, of subsidiaries of the Company with respect to the assets of the
  subsidiaries against which such creditors have a claim.  At September 30, 
  1995 the Company's subsidiaries had approximately $119.8 million of trade 
  payables and accrued liabilities.    

  Absence of Existing Market for Notes

       There is no established public trading market for the Notes.  The Company
  does not intend to list the Notes on any national securities exchange or to
  seek the admission thereof to trading in the National Association of
  Securities Dealers Automated Quotation system.  The Company has been advised
  by Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ") and PaineWebber
  Incorporated ("PaineWebber"), the initial purchasers of the Notes (the
  "Initial Purchasers"), that DLJ and PaineWebber are making and currently
  intend to continue making a market in the Notes.  However, DLJ and

                                       5.
<PAGE>
 
  PaineWebber are not obligated to make such a market and any market-making
  activities may be discontinued at any time without notice.  In addition, such
  market-making activity is subject to the limits imposed by the Securities Act
  and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
  may be limited during the pendency of the shelf registration statement to
  which this Prospectus relates.  See "Description of the Notes-Registration
  Rights; Liquidated Damages." Although the Notes have been designated for
  trading through PORTAL, no assurance can be given that an active trading
  market for the Notes will develop or, if such market develops, as to the
  liquidity or sustainability of such market.  If a trading market does not
  develop or is not maintained, holders of the Notes may experience difficulty
  in reselling the Notes or may be unable to sell them at all.  If a market for
  the Notes develops, any such market may be discontinued at any time.  If a
  public trading market develops for the Notes, future trading prices of the
  Notes will depend on many factors, including, among other things, prevailing
  interest rates, the Company's results of operations and the market for similar
  securities.  Depending on prevailing interest rates, the market for similar
  securities and other factors, including the financial condition of the
  Company, the Notes may trade at a discount from their principal amount.

                            DESCRIPTION OF THE NOTES

      Set forth below is a summary of certain provisions of the Notes.  The
  Notes were issued pursuant to an indenture (the "Indenture") dated as of
  September 18, 1995, by and between the Company and The First National Bank of
  Boston, as trustee (the "Trustee").  State Street Bank and Trust Company is
  the successor to The First National Bank of Boston, as Trustee.  The following
  summary of the Notes, the Indenture and the Registration Rights Agreement does
  not purport to be complete and is subject to, and is qualified in its entirety
  by, reference to all of the provisions of the Indenture and the Registration
  Rights Agreement, including the definitions thereof.  Copies of the Indenture
  and the Registration Rights Agreement can be obtained from the Company upon
  request.  Capitalized terms used herein without definition have the meanings
  ascribed to them in the Indenture or the Registration Rights Agreement, as
  appropriate.  As used in this section, "the Company" refers to United States
  Filter Corporation, exclusive of its subsidiaries.  Wherever particular
  provisions of the Indenture are referred to in this summary, such provisions
  are incorporated by reference as a part of the statements made and such
  statements are qualified in their entirety by such reference.

  General

      The Notes are unsecured, subordinated, general obligations of the Company,
  limited in aggregate principal amount to $140,000,000.  The Notes are
  subordinated in right of payment to all Senior Indebtedness of the Company, as
  described under "Subordination" below.  The Notes were issued only in fully
  registered form, without coupons, in denominations of $1,000 and integral
  multiples thereof.

      The Notes mature on September 15, 2005.  The Notes bear interest at 6% per
  annum from the date of issuance or from the most recent Interest Payment Date
  to which interest has been paid or provided for, payable semi-annually on
  March 15 and September 15 of each year, commencing March 15, 1996, to the
  persons in whose names such Notes are registered at the close of business on
  March 1 or September 1 immediately preceding such Interest Payment Date.
  Principal of, premium, if any, and interest on, and liquidated damages with
  respect to, the Notes will be payable, the Notes will be convertible and the
  Notes may be presented for registration of transfer or exchange, at the office
  or agency of the Company maintained for such purpose, which office or agency
  shall be maintained in the Borough of Manhattan, The City of New York.
  Interest will be calculated on the basis of a 360-day year consisting of
  twelve 30-day months.

      At the option of the Company, payment of interest and liquidated damages
  may be made by check mailed to the Holders of the Notes at the addresses set
  forth upon the registry books of the Company.  No service charge will be made
  for any registration of transfer or exchange of Notes, but the Company may
  require payment of a sum sufficient to cover any tax or other governmental
  charge payable in connection therewith.  Until otherwise designated by the
  Company, the Company's office or agency is the corporate trust office of the
  Trustee presently located at 150 Royall Street, Canton, Massachusetts 02021.

  Conversion Rights

      The Holder of any Notes has the right, at the Holder's option, to convert
  any portion of the principal amount thereof that is an integral multiple of $
  1,000 into shares of Common Stock at any time prior to the second Business Day
  prior to the Stated Maturity of the Note (unless earlier redeemed or
  repurchased) at the Conversion Price of $27.50 per share (equivalent to a
  conversion rate of 36.36 shares per $1,000 principal amount of Notes) (subject
  to adjustment as described below).  The right to convert a Note called for
  redemption or delivered for repurchase will terminate at the close of business
  on the fifth or second Business Day, respectively, prior to the Redemption
  Date or Repurchase Date for such Note, unless the Company subsequently fails
  to pay the applicable Redemption Price or Repurchase Price, as the case may
  be.

      In the case of any Note that has been converted after any Record Date, but
  on or before the next Interest Payment Date, interest the stated due date of
  which is on such Interest Payment Date shall be payable on such Interest
  Payment Date notwithstanding such conversion, and such interest shall be paid

                                       7.
<PAGE>
  
  to the Holder of such Note who is a Holder on such Record Date.  Any Note so
  converted must be accompanied by payment of an amount equal to the interest
  payable on such Interest Payment Date on the principal amount of Notes being
  surrendered for conversion.  No fractional shares will be issued upon
  conversion but, in lieu thereof, an appropriate amount will be paid in cash by
  the Company based on the market price of Common Stock (as determined in
  accordance with the Indenture) at the close of business on the day of
  conversion.

      The Conversion Price is subject to adjustment in certain events,
  including: (a) any payment of a dividend (or other distribution) payable in
  Common Stock on any class of Capital Stock of the Company, (b) any issuance to
  all holders of Common Stock of rights, options or warrants entitling them to
  subscribe for or purchase Common Stock at less than the then current market
  price (as determined in accordance with the Indenture) of Common Stock,
  provided, however, that if such options or warrants are only exercisable upon
  the occurrence of certain triggering events, then the conversion price will
  not be adjusted until such triggering events occur, (c) any subdivision,
  combination or reclassification of Common Stock, (d) any distribution to all
  holders of Common Stock of evidences of indebtedness, shares of Capital Stock
  other than Common Stock, cash or other assets (including securities, but
  excluding those dividends, rights, options, warrants and distributions
  referred to above and excluding dividends and distributions paid exclusively
  in cash), (e) any distribution consisting exclusively of cash (excluding any
  cash portion of distributions referred to in (d) above, or cash distributed
  upon a merger or consolidation to which the second succeeding paragraph
  applies) to all holders of Common Stock in an aggregate amount that, combined
  together with (i) all other such all-cash distributions made within the then
  preceding 12 months in respect of which no adjustment has been made and (ii)
  any cash and the fair market value of other consideration paid or payable in
  respect of any tender offer by the Company or any of its subsidiaries for
  Common Stock concluded within the preceding 12 months in respect of which no
  adjustment has been made, exceeds 15% of the Company's market capitalization
  (defined as being the product of the then current market price of the Common
  Stock times the number of shares of Common Stock then outstanding) on the
  record date of such distribution, and (f) the completion of a tender offer
  made by the Company or any of its Subsidiaries for Common Stock that involves
  an aggregate consideration that, together with (i) any cash and other
  consideration payable in a tender offer by the Company or any of its
  Subsidiaries for Common Stock expiring within the 12 months preceding the
  expiration of such tender offer in respect of which no adjustment has been
  made and (ii) the aggregate amount of any such all-cash distributions referred
  to in (e) above to all holders of Common Stock within the 12 months preceding
  the expiration of such tender offer in respect of which no adjustments have
  been made, exceeds 15% of the Company's market capitalization on the
  expiration of such tender offer.  The Company reserves the right to make such
  reductions in the conversion price in addition to those required in the
  foregoing provisions as it considers to be advisable in order that any event
  treated for Federal income tax purposes as a dividend of stock or stock rights
  will not be taxable to the recipients.  No adjustment of the conversion price
  is required to be made until the cumulative adjustments amount to 1.0% or more
  of the conversion price as last adjusted.

      In the event that the Company distributes rights or warrants (other than
  those referred to in (b) in the preceding paragraph) pro rata to holders of
  Common Stock, so long as any such rights or warrants have not expired or been
  redeemed by the Company, the Holder of any Note surrendered for conversion is
  entitled to receive upon such conversion, in addition to the shares of Common
  Stock issuable upon such conversion (the "Conversion Shares"), a number of
  rights or warrants to be determined as follows:  (i) if such conversion occurs
  on or prior to the date for the distribution to the holders of rights or
  warrants of separate certificates evidencing such rights or warrants (the
  "Distribution Date"), the same number of rights or warrants to which a holder
  of a number of shares of Common Stock equal to the number of Conversion Shares
  is entitled at the time of such conversion in accordance with the terms and
  provisions of and applicable to the rights or warrants, and (ii) if such
  conversion occurs after such Distribution Date, the same number of rights or
  warrants to which a holder of the number of shares of Common Stock into which
  such Note was convertible immediately prior to such Distribution Date would
  have been entitled on such Distribution Date in accordance with the terms and
  provisions of and applicable to the rights or warrants.  The conversion price
  of the Notes is not subject to adjustment on account of any declaration,
  distribution or exercise of such rights or warrants.

                                       8.
<PAGE>
  
      In case of any reclassification, consolidation or merger of the Company
  with or into another Person or any merger of another Person with or into the
  Company (with certain exceptions), or in case of any sale, transfer or
  conveyance of all or substantially all of the assets of the Company (computed
  on a consolidated basis), each Note then outstanding will, without the consent
  of any Holder of Notes, become convertible only into the kind and amount of
  securities, cash and other property receivable upon such reclassification,
  consolidation, merger, sale, transfer or conveyance by a holder of the number
  of shares of Common Stock into which such Note was convertible immediately
  prior thereto, after giving effect to any adjustment event, who failed to
  exercise any rights of election and received per share the kind and amount
  received per share by a plurality of non-electing shares.

      The Company will use its best efforts to cause all registrations with, and
  to obtain any approvals by, any governmental authority under any Federal or
  state law of the United States that may be required in connection with the
  conversion of the Notes into Common Stock.  If at any time during the three-
  year period following September 18, 1995, a registration statement under the
  Securities Act covering the shares of Common Stock issuable upon conversion of
  the Notes is not effective, shares of Common Stock issued upon conversion of
  the Notes ("Restricted Shares") may not be sold or otherwise transferred
  except in accordance with or pursuant to an exemption from, or otherwise in a
  transaction not subject to, the registration requirements of the Securities
  Act and, if a registration statement under the Securities Act is not effective
  at the time of a conversion, the Restricted Shares will bear a legend to that
  effect.  The Transfer Agent for the Common Stock is not required to accept for
  registration or transfer any Restricted Shares, except upon presentation of
  satisfactory evidence that these restrictions on transfer have been complied
  with, all in accordance with such reasonable regulations as the Company may
  from time to time agree with the Transfer Agent.  Under certain circumstances,
  the holders of the Notes are entitled to liquidated damages during such
  period.  See "Description of the Notes-Registration Rights; Liquidated
  Damages."

  Subordination
     
      The Notes are general, unsecured obligations of the Company, subordinated
  in right of payment to all existing and future Senior Indebtedness of the
  Company and rank pari passu in all respects with other unsecured subordinated
  indebtedness of the Company, including the 5% Convertible Subordinated
  Debentures due 2000.  The Notes are structurally subordinated in right of
  payment to all liabilities (including trade payables and capitalized lease
  obligations) of the Company's subsidiaries. At September 30, 1995 the Company
  had $14,573,000 of Senior Indebtedness outstanding. The rights of Holders are
  subordinated by operation of law to all existing and future indebtedness of
  the Company's subsidiaries, which as of September 30, 1995 was approximately
  $119,822,000 of trade payables and accrued liabilities. The Indenture does not
  restrict the incurrence of Senior Indebtedness or other indebtedness by the
  Company or its Subsidiaries.    

      The Indenture provides that no payment may be made by the Company on
  account of the principal of, premium, if any, interest on, or liquidated
  damages with respect to, the Notes, or to acquire any of the Notes (including
  repurchases of Notes at the option of the Holder) for cash or property (other
  than Junior Securities), or on account of the redemption provisions of the
  Notes, (i) upon the maturity of any Senior Indebtedness of the Company by
  lapse of time, acceleration (unless waived) or otherwise, unless and until all
  principal of, premium, if any, and interest on such Senior Indebtedness are
  first paid in full (or such payment is duly provided for), or (ii) in the
  event of default in the payment of any principal of, premium, if any, or
  interest on any Senior Indebtedness of the Company when it becomes due and
  payable, whether at maturity or at a date fixed for prepayment or by
  declaration or otherwise (a "Payment Default"), unless and until such Payment
  Default has been cured or waived or otherwise has ceased to exist.

                                       9.
<PAGE>
  
      Upon (i) the happening of an event of default (other than a Payment
  Default) that permits the holders of Senior Indebtedness or their
  representative immediately to accelerate its maturity and (ii) written notice
  of such event of default given to the Company and the Trustee by the holders
  of an aggregate of at least $20,000,000 principal amount outstanding of such
  Senior Indebtedness or their representative (a "Payment Notice"), then, unless
  and until such event of default has been cured or waived or otherwise has
  ceased to exist, no payment (by setoff or otherwise) may be made by or on
  behalf of the Company on account of the principal of, premium, if any,
  interest on, or liquidated damages with respect to, the Notes, or to acquire
  or repurchase any of the Notes for cash or property, or on account of the
  redemption provisions of the Notes, in any such case other than payments made
  with Junior Securities of the Company.  Notwithstanding the foregoing, unless
  (i) the Senior Indebtedness in respect of which such event of default exists
  has been declared due and payable in its entirety within 179 days after the
  Payment Notice is delivered as set forth above (the "Payment Blockage
  Period"), and (ii) such declaration has not been rescinded or waived, at the
  end of the Payment Blockage Period, the Company shall be required to pay all
  sums not paid to the Holders of the Notes during the Payment Blockage Period
  due to the foregoing prohibitions and to resume all other payments as and when
  due on the Notes.  Any number of Payment Notices may be given; provided,
  however, that (i) not more than one Payment Notice shall be given within a
  period of any 360 consecutive days, and (ii) no default that existed upon the
  date of such Payment Notice or the commencement of such Payment Blockage
  Period (whether or not such event of default is on the same issue of Senior
  Indebtedness) shall be made the basis for the commencement of any other
  Payment Blockage Period.

      In the event that, notwithstanding the foregoing, any payment or
  distribution of assets of the Company (other than Junior Securities) shall be
  received by the Trustee or the Holders at a time when such payment or
  distribution is prohibited by the foregoing provisions, such payment or
  distribution shall be held in trust for the benefit of the holders of Senior
  Indebtedness of the Company, and shall be paid or delivered by the Trustee or
  such Holders, as the case may be, to the holders of the Senior Indebtedness of
  the Company remaining unpaid or unprovided for or their representative or
  representatives, or to the trustee or trustees under any indenture pursuant to
  which any instruments evidencing any of such Senior Indebtedness of the
  Company may have been issued, ratably according to the aggregate amounts
  remaining unpaid on account of the Senior Indebtedness of the Company held or
  represented by each, for application to the payment of all Senior Indebtedness
  of the Company remaining unpaid, to the extent necessary to pay or to provide
  for the payment of all such Senior Indebtedness in full after giving effect to
  any concurrent payment or distribution to the holders of such Senior
  Indebtedness.

      Upon any distribution of assets of the Company upon any dissolution,
  winding up, total or partial liquidation or reorganization of the Company,
  whether voluntary or involuntary, in bankruptcy, insolvency, receivership or a
  similar proceeding or upon assignment for the benefit of creditors or any
  marshalling of assets or liabilities, (i) the holders of all Senior
  Indebtedness of the Company will first be entitled to receive payment in full
  (or have such payment duly provided for) before the Holders are entitled to
  receive any payment on account of the principal of, premium, if any, interest
  on, and liquidated damages with respect to, the Notes (other than Junior
  Securities) and (ii) any payment or distribution of assets of the Company of
  any kind or character, whether in cash, property or securities (other than
  Junior Securities) to which the Holders or the Trustee on behalf of the
  Holders would be entitled (by setoff or otherwise), except for the
  subordination provisions contained in the Indenture, will be paid by the
  liquidating trustee or agent or other person making such a payment or
  distribution directly to the holders of Senior Indebtedness of the Company or
  their representative to the extent necessary to make payment in full of all
  such Senior Indebtedness remaining unpaid, after giving effect to any
  concurrent payment or distribution to the holders of such Senior Indebtedness.

      No provision contained in the Indenture or the Notes affects the
  obligation of the Company, which is absolute and unconditional, to pay, when
  due, principal of, premium, if any, interest on, and liquidated damages with
  respect, to the Notes.  The subordination provisions of the Indenture and the
  Notes do not prevent the occurrence of any Default or Event of Default under
  the Indenture or limit the rights of the Trustee or any Holder, subject to the
  two preceding previous paragraphs, to pursue any other rights or remedies with
  respect to the Notes.

                                      10.
<PAGE>
  
      As a result of these subordination provisions, in the event of the
  liquidation, bankruptcy, reorganization, insolvency, receivership or similar
  proceeding or an assignment for the benefit of the creditors of the Company or
  any of its Subsidiaries or a marshalling of assets or liabilities of the
  Company and its Subsidiaries, Holders of the Notes may receive ratably less
  than other creditors.

      The Company conducts its operations through its Subsidiaries.
  Accordingly, the Company's ability to meet its cash obligations is dependent
  upon the ability of its Subsidiaries to make cash distributions to the
  Company.  The ability of its Subsidiaries to make distributions to the Company
  is and will continue to be restricted by, among other limitations, applicable
  provisions of the laws of national and state governments and contractual
  provisions.  The Indenture does not limit the ability of the Company's
  subsidiaries to incur such restrictions in the future.  The right of the
  Company to participate in the assets of any Subsidiary (and thus the ability
  of holders of the Notes to benefit indirectly from such assets) is generally
  subject to the prior claims of creditors, including trade creditors, of that
  Subsidiary except to the extent that the Company is recognized as a creditor
  of such Subsidiary, in which case the Company's claims would still be subject
  to any security interest of other creditors of such Subsidiary.  The Notes,
  therefore, are structurally subordinated to creditors, including trade
  creditors, of Subsidiaries of the Company with respect to the assets of the
  Subsidiaries against which such creditors have a claim.

  Redemption at the Company's Option

      The Notes are not subject to redemption prior to September 23, 1998 and
  are redeemable on such date and thereafter at the option of the Company, in
  whole or in part, upon not less than 30 nor more than 60 days' notice to each
  Holder, at the following redemption prices (expressed as percentages of the
  principal amount) if redeemed during the 12-month period commencing September
  15 of the years indicated below, in each case (subject to the right of Holders
  of record on a Record Date to receive interest due on an Interest Payment Date
  that is on or prior to such Redemption Date) together with accrued and unpaid
  interest and liquidated damages, if any, to the Redemption Date:

<TABLE>
<CAPTION>
               Year...............................    Percentage
               ----...............................    ----------
               <S>................................     <C>
               1998...............................     103.75%
               1999...............................     103.00%
               2000...............................     102.25%

               2003 and thereafter................       100%
</TABLE>

      In the case of a partial redemption, the Trustee shall select the Notes or
  portions thereof for redemption on a pro rata basis, by lot or in such other
  manner it deems appropriate and fair.  The Notes may be redeemed in part in
  multiples of $1,000 only.

       The Notes will not have the benefit of any sinking fund.

      Notice of any redemption will be sent, by first-class mail, at least 30
  days and not more than 60 days prior to the date fixed for redemption, to the
  Holder of each Note to be redeemed to such Holder's last address as then shown
  upon the registry books of the Registrar.  The notice of redemption must state
  the Redemption Date, the Redemption Price and the amount of accrued interest
  to be paid.  Any notice that relates to a Note to be redeemed in part only
  must state the portion of the principal amount equal to the unredeemed portion
  thereof and must state that on and after the Redemption Date, upon surrender
  of such Note, a new Note or Notes in principal amount equal to the unredeemed
  portion thereof will be issued.  On and after the Redemption Date, interest
  will cease to accrue on the Notes or portions thereof called for redemption,
  unless the Company defaults in its obligations with respect thereto.

                                      11.

  Repurchase of Notes at the Option of the Holder Upon a Change of Control

      The Indenture provides that in the event that a Change of Control (as
  defined) has occurred, each Holder of Notes will have the right, at such
  Holder's option, pursuant to an irrevocable and unconditional offer by the
  Company (the "Repurchase Offer"), to require the Company to repurchase all or
  any part of such Holder's Notes (provided, that the principal amount of such
  Notes must be $1,000 or an integral multiple thereof) on the date (the
  "Repurchase Date") that is no later than 40 Business Days after the occurrence
  of such Change of Control at a cash price (the "Repurchase Price") equal to
  101% of the principal amount thereof, together with accrued and unpaid
  interest to the Repurchase Date.  The Repurchase Offer shall be made within 15
  Business Days following a Change of Control and shall remain open for 20
  Business Days following its commencement (the "Repurchase Offer Period").
  Upon expiration of the Repurchase Offer Period, the Company shall purchase all
  Notes tendered in response to the Repurchase Offer.  If required by applicable
  law, the Repurchase Date and the Repurchase Offer Period may be extended as so
  required; however, if so extended, it shall nevertheless constitute an Event
  of Default if the Repurchase Date does not occur within 60 Business Days of
  the Change of Control.

      The Indenture provides that a "Change of Control" occurs (i) upon any
  merger or consolidation of the Company with or into any person or any sale,
  transfer or other conveyance, whether direct or indirect, of all or
  substantially all of the assets of the Company, on a consolidated basis, in
  one transaction or a series of related transactions, if, immediately after
  giving effect to such transaction, any "person" or "group" (as such terms are
  used for purposes of Sections 13(d) and 14(d) of the Exchange Act, whether or
  not applicable) is or becomes the "beneficial owner," directly or indirectly,
  of more than 50% of the total voting power in the aggregate normally entitled
  to vote in the election of directors, managers, or trustees, as applicable, of
  the transferee or surviving entity, (ii) when any "person's or "group" (as
  such terms are used for purposes of Sections 13(d) and 14(d) of the Exchange
  Act, whether or not applicable) is or becomes the "beneficial owner," directly
  or indirectly, of more than 50% of the total voting power in the aggregate
  normally entitled to vote in the election of directors of the Company, or
  (iii) when, during any period of 12 consecutive months after the Issue Date,
  individuals who at the beginning of any such 12-month period constituted the
  Board of Directors of the Company (together with any new directors whose
  election by such Board or whose nomination for election by the shareholders of
  the Company was approved by a vote of a majority of the directors then still
  in office who were either directors at the beginning of such period or whose
  election or nomination for election was previously so approved), cease for any
  reason to constitute a majority of the Board of Directors of the Company then
  in office.

      On or before the Repurchase Date, the Company will (i) accept for payment
  Notes or portions thereof properly tendered pursuant to the Repurchase Offer,
  (ii) deposit with the Paying Agent cash sufficient to pay the Repurchase Price
  (together with accrued and unpaid interest) of all Notes so tendered and (iii)
  deliver to the Trustee Notes so accepted, together with an Officers'
  Certificate listing the Notes or portions thereof being purchased by the
  Company.  The Paying Agent will promptly mail to the Holders of Notes so
  accepted payment in an amount equal to the Repurchase Price (together with
  accrued and unpaid interest), and the Trustee will promptly authenticate and
  mail or deliver to such Holders a new Note or Notes equal in principal amount
  to any unpurchased portion of the Notes surrendered.  Any Notes not so
  accepted will be promptly mailed or delivered by the Company to the Holder
  thereof.  The Company will publicly announce the results of the Repurchase
  Offer on or as soon as practicable after the Repurchase Date.

      The phrase "all or substantially all" of the assets of the Company is
  likely to be interpreted by reference to applicable state law at the relevant
  time, and will be dependent on the facts and circumstances existing at such
  time.  As a result, there may be a degree of uncertainty in ascertaining
  whether a sale or transfer of "all or substantially all" of the assets of the
  Company has occurred.  In addition, no assurances can be given that the
  Company will be able to acquire the Notes tendered upon the occurrence of a
  Change of Control.

      For purposes of this definition, (i) the terms "person" and "group" shall
  have the meaning used for purposes of Rules 13d-3 and 13d-5 of the Exchange
  Act as in effect on the Issue Date, whether or not applicable; and (ii) the
  term "beneficial owner" shall have the meaning used in Rules 13d-3 and 13d-5

                                      12.

  under the Exchange Act as in effect on the Issue Date, whether or not
  applicable, except that a "person" shall be deemed to have "beneficial
  ownership" of all shares that any such person has the right to acquire,
  whether such right is exercisable immediately or only after the passage of
  time or upon the occurrence of certain events.

      The Change of Control purchase feature of the Notes may make more
  difficult or discourage a takeover of the Company, and, thus, the removal of
  incumbent management.  The Change of Control purchase feature resulted from
  negotiations between the Company and the Initial Purchasers.

      The provisions of the Indenture relating to a Change of Control may not
  afford the Holders protection in the event of a highly leveraged transaction,
  reorganization, restructuring, merger, spin-off or similar transaction that
  may adversely affect Holders, if such transaction does not constitute a Change
  of Control, as set forth above.  In addition, the Company may not have
  sufficient financial resources available to fulfill its obligation to
  repurchase the Notes upon a Change of Control or to repurchase other debt
  securities of the Company or its Subsidiaries providing similar rights to the
  holders thereof.

      To the extent applicable and if required by law, the Company will comply
  with Section 14 of the Exchange Act and the provisions of Regulation 14E and
  any other tender offer rules under the Exchange Act and any other securities
  laws, rules and regulations that may then be applicable to any offer by the
  Company to purchase the Notes at the option of Holders upon a Change of
  Control.

      The right to require the Company to repurchase Notes as a result of the
  occurrence of a Change of Control could create an event of default under
  Senior Indebtedness as a result of which any repurchase could, absent a
  waiver, be blocked by the subordination provision of the Notes.  See "-
  Subordination." Failure of the Company to repurchase the Notes when required
  would result in an Event of Default with respect to the Notes whether or not
  such repurchase is permitted by the subordination provisions.

  Rule 144A Information Requirement

      The Company has agreed to furnish to the Holders or beneficial holders of
  the Notes or the underlying Common Stock and prospective purchasers of the
  Notes or the underlying Common Stock designated by the Holders of the Notes or
  the underlying Common Stock, upon their request, the information required to
  be delivered pursuant to Rule 144A(d)(4) under the Securities Act until such
  time as such securities are no longer "restricted securities" within the
  meaning of Rule 144 under the Securities Act.

  Limitation on Merger, Sale or Consolidation

      The Indenture provides that the Company may not, directly or indirectly,
  consolidate with or merge with or into another person or sell, lease, convey
  or transfer all or substantially all of its assets (computed on a consolidated
  basis), whether in a single transaction or a series of related transactions,
  to another Person or group of affiliated Persons, unless (i) either (a) in the
  case of a merger or consolidation the Company is the surviving entity or (b)
  the resulting, surviving or transferee entity is a corporation organized under
  the laws of the United States, any state thereof or the District of Columbia
  and expressly assumes by supplemental indenture all of the obligations of the
  Company in connection with the Notes and the Indenture; and (ii) no Default or
  Event of Default shall exist or shall occur immediately after giving effect on
  a pro forma basis to such transaction.

      Upon any consolidation or merger or any transfer of all or substantially
  all of the assets of the Company in accordance with the foregoing, the
  successor corporation formed by such consolidation or into which the Company
  is merged or to which such transfer is made, shall succeed to, and be
  substituted for, and may exercise every right and power of, the Company under
  the Indenture with the same effect as if such successor corporation had been
  named therein as the Company, and the Company will be released from its
  obligations under the Indenture and the Notes, except as to any obligations
  that arise from or as a result of such transaction.

                                      13.

  Reports

      Whether or not the Company is subject to the reporting requirements of
  Section 13 or 15(d) of the Exchange Act, the Company shall deliver to the
  Trustee and to each Holder, within 15 days after it is or would have been
  required to file such with the SEC, annual and quarterly consolidated
  financial statements substantially equivalent to financial statements that
  would have been included in reports filed with the SEC if the Company was
  subject to the requirements of Section 13 or 15(d) of the Exchange Act,
  including, with respect to annual information only, a report thereon by the
  Company's certified independent public accountants as such would be required
  in such reports to the SEC and, in each case, together with a management's
  discussion and analysis of financial condition and results of operations as
  such would be so required.

  Events of Default and Remedies

      The Indenture defines an Event of Default as (i) the failure by the
  Company to pay any installment of interest on, or liquidated damages with
  respect to, the Notes as and when due and payable and the continuance of any
  such failure for 30 days, (ii) the failure by the Company to pay all or any
  part of the principal of, or premium, if any on the Notes when and as the same
  become due and payable at maturity, redemption, by acceleration or otherwise,
  including, without limitation, pursuant to any Repurchase Offer or otherwise,
  (iii) the failure of the Company to perform any conversion of Notes required
  under the Indenture and the continuance of any such failure for 30 days, (iv)
  the failure by the Company to observe or perform any other covenant or
  agreement contained in the Notes or the Indenture and, subject to certain
  exceptions, the continuance of such failure for a period of 60 days after
  written notice is given to the Company by the Trustee or to the Company and
  the Trustee by the Holders of at least 25% in aggregate principal amount of
  the Notes outstanding, (v) certain events of bankruptcy, insolvency or
  reorganization in respect of the Company or any of its Subsidiaries, (vi) a
  default in the payment of principal, premium or interest when due that extends
  beyond any stated period of grace applicable thereto or an acceleration for
  any other reason of the maturity of any Indebtedness of the Company or any of
  its Subsidiaries with an aggregate principal amount in excess of $15 million,
  and (vii) final unsatisfied judgments not covered by insurance aggregating in
  excess of $15 million, at any one time rendered against the Company or any of
  its Subsidiaries and not stayed, bonded or discharged within 75 days.  The
  Indenture provides that if a Default occurs and is continuing, the Trustee
  must, within 90 days after the occurrence of such default, give to the Holders
  notice of such default.

      The Indenture provides that if an Event of Default occurs and is
  continuing (other than an Event of Default specified in clause (v) above),
  then in every such case, unless the principal of all of the Notes shall have
  already become due and payable, either the Trustee or the Holders of 25% in
  aggregate principal amount of the Notes then outstanding, by notice in writing
  to the Company (and to the Trustee if given by Holders) (an "Acceleration
  Notice"), may declare all principal and accrued interest thereon to be due and
  payable immediately.  If an Event of Default specified in clause (v) above
  occurs, all principal and accrued interest thereon will be immediately due and
  payable on all outstanding Notes without any declaration or other act on the
  part of the Trustee or the Holders.  The Holders of no less than a majority in
  aggregate principal amount of Notes generally are authorized to rescind such
  acceleration if all existing Events of Default, other than the non-payment of
  the principal of, premium, if any, and interest on, and liquidated damages
  with respect to, the Notes that have become due solely by such acceleration,
  have been cured or waived.

      Prior to the declaration of acceleration of the maturity of the Notes, the
  Holders of a majority in aggregate principal amount of the Notes at the time
  outstanding may waive on behalf of all the Holders any default, except a
  default in the payment of principal of or interest on any Note not yet cured,
  or a default with respect to any covenant or provision that cannot be modified
  or amended without the consent of the Holder of each outstanding Note
  affected.  Subject to the provisions of the Indenture relating to the duties
  of the Trustee, the Trustee is under no obligation to exercise any of its
  rights or powers under the Indenture at the request, order or direction of any
  of the Holders, unless such Holders have offered to the Trustee reasonable
  security or indemnity.  Subject to all provisions of the Indenture and
  applicable law, the Holders of a majority in aggregate principal amount of the
  Notes at the time outstanding have the right

                                      14.
<PAGE>
  
  to direct the time, method and place of conducting any proceeding for any
  remedy available to the Trustee, or exercising any trust or power conferred on
  the Trustee.

  Amendments and Supplements

      The Indenture contains provisions permitting the Company and the Trustee
  to enter into a supplemental indenture for certain limited purposes without
  the consent of the Holders.  With the consent of the Holders of not less than
  a majority in aggregate principal amount of the Notes at the time outstanding,
  the Company and the Trustee are permitted to amend or supplement the Indenture
  or any supplemental indenture or modify the rights of the Holders; provided,
  that no such modification may, without the consent of each Holder affected
  thereby: (i) change the Stated Maturity of any Note or reduce the principal
  amount thereof or the rate (or extend the time for payment) of interest
  thereon or any premium payable upon the redemption thereof, or change the
  place of payment where, or the coin or currency in which, any Note or any
  premium or the interest thereon is payable, or impair the right to institute
  suit for the enforcement of any such payment or the conversion of any Note on
  or after the due date thereof (including, in the case of redemption, on or
  after the Redemption Date), or reduce the Repurchase Price, or alter the
  Repurchase Offer or redemption provisions in a manner adverse to the Holders,
  or (ii) reduce the percentage in principal amount of the outstanding Notes,
  the consent of whose Holders is required for any such amendment, supplemental
  indenture or waiver provided for in the Indenture, or (iii) adversely affect
  the right of such Holder to convert Notes, or (iv) modify any of the waiver
  provisions, except to increase any required percentage or to provide that
  certain other provisions of the Indenture cannot be modified or waived without
  the consent of the Holder of each outstanding Note affected thereby.

  No Personal Liability of Stockholders, Officer, Directors and Employees

      The Indenture provides that no stockholder, employee, officer or director,
  as such, past, present or future of the Company or any successor corporation
  shall have any personal liability in respect of the obligations of the Company
  under the Indenture or the Notes by reason of his, her or its status as such
  stockholder, employee, officer or director.

  Transfer and Exchange

      A Holder may transfer or exchange the Notes in accordance with the
  Indenture.  The Company may require a Holder, among other things, to furnish
  appropriate endorsements and transfer documents, and to pay any taxes and fees
  required by law or permitted by the Indenture.  The Company is not required to
  transfer or exchange any Notes selected for redemption.  Also, the Company is
  not required to transfer or exchange any Notes for a period of 15 days before
  a selection of Notes to be redeemed.

       The registered holder of a Note may be treated as the owner of it for all
  purposes.

  Book-Entry, Delivery and Form

      Except as set forth below, the Notes were initially issued in the form of
  registered Notes in global form (the "Global Notes").  Each Global Note was
  deposited on the date of the closing of the sale of the Notes (the "Closing
  Date") with, or on behalf of, The Depository Trust Company (the "Depositary")
  and registered in the name of Cede & Co., as nominee of the Depositary.
  Interests in Global Notes are available for purchase only by "qualified
  institutional buyers," as defined in Rule 144A under the Securities Act
  ("QIBs").

      Notes that were (i) originally issued to or transferred to institutional
  "accredited investors," as defined in Rule 501(a)(1), (2), (3) or (7) under
  the Securities Act, who are not QlBs or to any other persons who are not QIBs
  or (ii) issued as described below under "Certificated Notes," were issued in
  the form of registered definitive securities ("Certificated Notes").  Upon the
  transfer to a QIB of Certificated Notes, such Certificated Notes will, unless
  the Global Note has previously been exchanged for Certificated

                                      15.
<PAGE>
  
  Notes, be exchanged for an interest in the Global Note representing the
  principal amount of Notes being transferred.

      The Depositary has advised the Company that it is a limited-purpose trust
  company that was created to hold securities for its participating
  organizations (collectively, the "Participants") and to facilitate the
  clearance and settlement of transactions in such securities between
  Participants through electronic book-entry changes in accounts of its
  Participants.  The Depositary's Participants include securities brokers and
  dealers (including the Initial Purchasers), banks and trust companies,
  clearing corporations and certain other organizations.  Access to the
  Depositary's system is also available to other entities such as banks,
  brokers, dealers and trust companies (collectively, "Indirect Participants")
  that clear through or maintain a custodial relationship with a Participant,
  either directly or indirectly.  QIBs may elect to hold Notes purchased by them
  through the Depositary.  QIBs who are not Participants may beneficially own
  securities held by or on behalf of the Depositary only through Participants or
  Indirect Participants.  Persons that are not QIBs may not hold Notes through
  the Depositary.

      The Company expects that pursuant to procedures established by the
  Depositary (i) upon deposit of the Global Notes, the Depositary will credit
  the accounts of Participants designated by the Initial Purchasers with an
  interest in the Global Note and (ii) ownership of the Notes evidenced by the
  Global Note will be shown on, and the transfer of ownership thereof will be
  effected only through, records maintained by the Depositary (with respect to
  the interests of Participants), the Participants and the Indirect
  Participants.  The laws of some states require that certain persons take
  physical delivery in definitive form of securities that they own and that
  security interests in negotiable instruments can only be perfected by delivery
  of certificates representing the instruments.  Consequently, the ability to
  transfer Notes evidenced by the Global Note will be limited to such extent.

      So long as the Depositary or its nominee is the registered owner of a
  Note, the Depositary or such nominee, as the case may be, will be considered
  the sole owner or holder of the Notes represented by the Global Note for all
  purposes under the Indenture.  Except as provided below, owners of beneficial
  interests in a Global Note will not be entitled to have Notes represented by
  such Global Note registered in their names, will not receive or be entitled to
  receive physical delivery of Certificated Notes, and will not be considered
  the owners or holders thereof under the Indenture for any purpose, including
  with respect to the giving of any directions, instructions or approvals to the
  Trustee thereunder.  As a result, the ability of a person having a beneficial
  interest in Notes represented by a Global Note to pledge such interest to
  persons or entities that do not participate in the Depositary's system, or to
  otherwise take actions with respect to such interest, may be affected by the
  lack of a physical certificate evidencing such interest.

      Neither the Company nor the Trustee has any responsibility or liability
  for any aspect of the records relating to or payments made on account of Notes
  by the Depositary, or for maintaining, supervising or reviewing any records of
  the Depositary relating to such Notes.

      Payments with respect to the principal of, premium, if any, interest on,
  and liquidated damages with respect to, any Note represented by a Global Note
  registered in the name of the Depositary or its nominee on the applicable
  record date are payable by the Trustee to or at the direction of the
  Depositary or its nominee in its capacity as the registered Holder of the
  Global Note representing such Notes under the Indenture.  Under the terms of
  the Indenture, the Company and the Trustee may treat the persons in whose
  names the Notes, including the Global Notes, are registered as the owners
  thereof for the purpose of receiving such payments and for any and all other
  purposes whatsoever.  Consequently, neither the Company nor the Trustee has or
  will have any responsibility or liability for the payment of such amounts to
  beneficial owners of Notes (including principal, premium, if any, interest, or
  liquidated damages with respect thereto), or to immediately credit the
  accounts of the relevant Participants with such payment, in amounts
  proportionate to their respective holdings in principal amount of beneficial
  interests in the Global Note as shown on the records of the Depositary.
  Payments by the Participants and the Indirect Participants to the beneficial
  owners of Notes are governed by standing instructions and customary practice
  and are the responsibility of the Participants or the Indirect Participants.

                                      16.
<PAGE>
  
      Certificated Notes

      If (i) the Company notifies the Trustee in writing that the Depositary is
  no longer willing or able to act as a depositary and the Company is unable to
  locate a qualified successor within 90 days, or (ii) the Company, at its
  option, notifies the Trustee in writing that it elects to cause the issuance
  of Notes in definitive form under the Indenture, then, upon surrender by the
  Depositary of the Global Notes, Certificated Notes will be issued to each
  person that the Depositary identifies as the beneficial owner of the Notes
  represented by Global Notes.  In addition, subject to certain conditions, any
  person having a beneficial interest in a Global Note may, upon request to the
  Trustee, exchange such beneficial interest for Notes in the form of
  Certificated Notes.  Upon any such issuance, the Trustee is required to
  register such Certificated Notes in the name of such person or persons (or the
  nominee of any thereof), and cause the same to be delivered thereto.

      Neither the Company nor the Trustee shall be liable for any delay by the
  Depositary or any Participant or Indirect Participant in identifying the
  beneficial owners of the Notes, and the Company and the Trustee may
  conclusively rely on, and shall be protected in relying on, instructions from
  the Depositary for all purposes (including with respect to the registration
  and delivery, and the respective principal amounts, of the Notes to be
  issued).

  Same-Day Funds Settlement and Payment

      The Indenture requires that payments in respect of the Notes represented
  by the Global Notes (including principal, premium, if any, interest and
  liquidated damages with respect thereto) be made by wire transfer of
  immediately available funds to the accounts specified by the Depositary.  With
  respect to Notes represented by Certificated Notes, the Company will make all
  payments of principal, premium, if any, interest and liquidated damages with
  respect thereto, by mailing a check to each such Holder's registered address.
  Secondary trading in long-term notes and debentures of corporate issuers is
  generally settled in clearing-house or next-day funds.  In contrast, the Notes
  represented by the Global Notes have been designated for trading in the PORTAL
  market and to trade in the Depositary's Same-Day Funds Settlement System, and
  any permitted secondary market trading activity in such Notes will, therefore,
  be required by the Depositary to be settled in immediately available funds.
  The Company expects that secondary trading in the Certificated Notes will also
  be settled in immediately available funds.

  Registration Rights; Liquidated Damages

      The Company and the Initial Purchasers have entered into a Registration
  Rights Agreement dated as of September 18, 1995 (the "Registration Rights
  Agreement").

      Pursuant to the Registration Rights Agreement, the Company has filed with
  the SEC a shelf registration statement under the Securities Act (the "Shelf
  Registration Statement") on Form S-3, to cover resales of Transfer Restricted
  Securities by the holders thereof who satisfy certain conditions relating to
  the provision of information in connection with the Shelf Registration
  Statement.  The Company will use its best efforts to cause the applicable
  registration statement to be declared effective by the SEC as soon as
  practicable after the date of filing and to keep such registration statement
  effective until September 18, 1998, three years after the date of original
  issue of the Notes, or until the Shelf Registration Statement is no longer
  required for transfer of the Notes or the underlying Common Stock.  For
  purposes of the foregoing, "Transfer Restricted Securities" means each Note
  and share of Common Stock issued upon conversion thereof until the date on
  which such Note or share of Common Stock has been effectively registered under
  the Securities Act and disposed of in accordance with the Shelf Registration
  Statement or the date on which such Note or share of Common Stock is
  distributed to the public pursuant to Rule 144 under the Securities Act or is
  salable pursuant to Rule 144(k) under the Securities Act (or any similar
  provisions then in force).

      The Registration Rights Agreement provides that (i) the Company will file
  the Shelf Registration Statement with the SEC on or prior to 90 days after the
  Closing Date and (ii) the Company will use its best efforts to cause the Shelf
  Registration Statement to be declared effective by the SEC on or prior to 120

                                      17.
<PAGE>
  
  days after the Closing Date (the "Effectiveness Target Date").  If (i) the
  Shelf Registration Statement is not filed with the SEC on or prior to 90 days
  after the Closing Date, (ii) the Shelf Registration Statement has not been
  declared and effective by the SEC within 120 days after the Closing Date, or
  (iii) the Shelf Registration Statement is filed and declared effective but
  shall thereafter cease to be effective (without being succeeded immediately by
  an additional Shelf Registration Statement filed and declared effective) for a
  period of time which shall exceed 90 days in the aggregate per year (each such
  event referred to in clauses (i) through (iii), a "Registration Default"), the
  Company will pay liquidated damages to each Holder of Transfer Restricted
  Securities, during the first 90-day period immediately following the
  occurrence of such Registration Default, in an amount equal to $0.05 per week
  per $1,000 principal amount of Notes and, if applicable, $0.01 per week per
  share (subject to adjustment in the event of stock splits, stock
  recombinations, stock dividends and the like) of Common Stock constituting
  Transfer Restricted Securities held by such Holder.  The amount of the
  liquidated damages will increase by an additional $0.05 per week per $1,000
  principal amount or $0.01 per week per share (subject to adjustment as set
  forth above) of Common Stock constituting Transfer Restricted Securities for
  each subsequent 90-day period until the applicable Registration Statement is
  filed and the applicable Registration Statement is declared effective, or the
  Shelf Registration Statement again becomes effective, as the case may be, up
  to a maximum amount of liquidated damages with respect to any Registration
  Default of $0.25 per week per $1,000 principal amount of Notes or $0.05 per
  week per share (subject to adjustment as set forth above) of Common Stock
  constituting Transfer Restricted Securities.  All accrued liquidated damages
  shall be paid to holder of Notes by wire transfer of immediately available
  funds or by Federal funds check by the Company on each Damages Payment Date.
  Following the cure of a Registration Default, liquidated damages will cease to
  accrue with respect to such Registration Default.

      So long as the Notes and Common Stock are outstanding, the Company will
  continue to provide to holders of the Notes and Common Stock and to
  prospective purchasers of the Notes and Common Stock the information required
  by Rule 144A(d) (4), if applicable.  The Shelf Registration Statement will
  remain effective until the earlier of three years following the Closing or
  until the Shelf Registration Statement is no longer required for transfer of
  the Notes or the underlying Common Stock.

</TABLE>

      The preceding table has been prepared based upon information furnished to
  the Company by The Depository Trust Company ("DTC"), State Street Bank and
  Trust Company, trustee under the Indenture, and by or on behalf of the Selling
  Securityholders.

      Other than as a result of the ownership of Notes, none of the Selling
  Securityholders listed above had any material relationship with the Company
  within the three year period ending on the date of this Prospectus.

      Because the Selling Securityholders may offer all or some of the Notes
  that they hold and/or Conversion Shares pursuant to the offering contemplated
  by this Prospectus, and because there are currently no agreements,
  arrangements or understandings with respect to the sale of any of the Notes or
  Conversion Shares by the Selling Securityholders, no estimate can be given as
  to the principal amount of Notes or Conversion Shares that will be held by the
  Selling Securityholders after completion of this offering.  See "Plan of
  Distribution."

                                      21.

                             PLAN OF DISTRIBUTION

      The Company will not receive any of the proceeds from this offering.  The
  Notes and Conversion Shares offered hereby may be sold from time to time by or
  for the account of any of the Selling Securityholders or by their pledgees,
  donees or transferees or other successors in interest to the Selling
  Securityholders.  The Notes and the Conversion Shares may be sold hereunder
  directly to purchasers by the Selling Securityholders, in negotiated
  transactions; by or through brokers or dealers in ordinary brokerage
  transactions or transactions in which the broker solicits purchasers; block
  trades in which the broker or dealer will attempt to sell Notes or Conversion
  Shares as agent but may position and resell a portion of the block as
  principal; transactions in which a broker or dealer purchases as principal for
  resale for its own account; or through underwriters or agents.  The Notes or
  Conversion Shares may be sold at a fixed offering price, which may be changed,
  at the prevailing market price at the time of sale, at prices related to such
  prevailing market price or at negotiated prices.  Any brokers, dealers,
  underwriters or agents may arrange for others to participate in any such
  transaction and may receive compensation in the form of discounts, commissions
  or concessions from the Selling Securityholders and/or the purchasers of Notes
  or Conversion Shares.  Each Selling Securityholder will be responsible for
  payment of any and all commissions to brokers.  To the extent required, the
  name of any such broker, dealer, agent or underwriter and any applicable
  commissions with respect to a particular offer, including required information
  pertaining to that offer, will be set forth in an accompanying Prospectus
  Supplement.  The aggregate proceeds to the Selling Securityholders from the
  sale of the Notes and Conversion Shares offered by the Selling Securityholders
  hereby will be the purchase price of such Notes and Conversion Shares less any
  broker's commissions.

      The Company has been advised by DLJ and PaineWebber, the Initial
  Purchasers, that DLJ and PaineWebber are making and currently intend to
  continue making a market in the Notes.  However, DLJ and PaineWebber are not
  obligated to make such a market and any market-making activities may be
  discontinued at any time without notice.  There can be no assurance that an
  active market for the Notes will develop or continue.  The Company does not
  intend to apply for listing of the Notes on any securities exchange or for
  quotation through the National Association of Securities Dealers Automated
  Quotation System.  The Common Stock is listed and principally traded on the
  New York Stock Exchange.

      In order to comply with the securities laws of certain states, if
  applicable, the Notes and Conversion Shares will be sold in such jurisdiction
  only through registered or licensed brokers or dealers.  In addition, in
  certain states the Notes and Conversion Shares may not be sold unless they
  have been registered or qualified for sale in the applicable state or an
  exemption from the registration or qualification requirement is available and
  is complied with.

      The Selling Securityholders and any broker-dealers, agents or underwriters
  that participate with the Selling Securityholders in the distribution of the
  Notes or Conversion Shares may be deemed to be "underwriters" within the
  meaning of the Securities Act, in which event any commissions received by such
  broker-dealers, agents or underwriters and any profit on the resale of the
  Notes or Conversion Shares purchased by them may be deemed to be underwriting
  commissions or discounts under the Securities Act.

      Under applicable rules and regulations under the Exchange Act, any persons
  engaged in the distribution of the Notes or the Conversion Shares offered
  hereby may not simultaneously engage in market making activities with respect
  to either the Notes or the Conversion Shares for a period of nine business
  days (two business days in the case of Conversion Shares) prior to the
  commencement of such distribution.  In addition, and without limiting the
  foregoing, each Selling Securityholder will be subject to applicable
  provisions of the Exchange Act and the rules and regulations thereunder,
  including, without limitation, Rules 10b-2, 10b-5, 10b-6 and 10b-7, which
  provisions may limit the timing of purchases and sales of Notes or Conversion
  Shares by the Selling Securityholders.

      In addition, any securities covered by this Prospectus which qualify for
  sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under
  Rule 144 or Rule 144A rather than pursuant to this Prospectus.  There is no
  assurance that any Selling Securityholder will sell any or all of the Notes or

                                      22.

  Conversion Shares described herein, and any Selling Securityholder may
  transfer, devise or gift such securities by other means not described herein.

      The Notes were originally sold to DLJ and PaineWebber in September 1995 in
  a private placement.  The Company agreed to indemnify and hold DLJ and
  PaineWebber harmless against certain liabilities under the Securities Act that
  could arise in connection with the sale of the Notes by DLJ and PaineWebber.
  The Company and the Selling Securityholders are obligated to indemnify each
  other against certain liabilities arising under the Securities Act.

      The Company will use its best efforts to cause the registration statement
  to which this Prospectus relates to become effective as promptly as is
  practicable and to keep the registration statement effective until September
  18, 1998, three years after the date of original issue of the Notes, or until
  the Shelf Registration Statement is no longer required for transfer of the
  Notes or the underlying Common Stock.  The Company is permitted to suspend the
  use of this Prospectus in connection with sales of Notes and Conversion Shares
  by holders during certain periods of time under certain circumstances relating
  to pending corporate developments and public filings with the Commission and
  similar events.  Expenses of preparing and filing the registration statement
  and all post-effective amendments will be borne by the Company.


                          DESCRIPTION OF CAPITAL STOCK

      General.  As of October 3, 1995, the Company was authorized to issue
  75,000,000 shares of Common Stock, par value $.01 per share, of which
  25,509,909 shares were issued and outstanding, and 3,000,000 shares of
  preferred stock, par value $.10 per share, of which 880,000 shares have been
  designated Series A Voting Cumulative Convertible Preferred Stock ("Series A
  Preferred Stock"), all of which were issued and outstanding, and of which
  64,815 have been designated Series B Voting Convertible Preferred Stock, of
  which none were issued and outstanding.  Of the unissued shares of Common
  Stock, 1,320,000 shares were reserved for issuance upon conversion of the
  Series A Preferred Stock, 2,926,829 shares were reserved for issuance upon
  conversion of the Company's 5% Convertible Subordinated Debentures due 2000,
  5,090,909 shares were reserved for issuance upon conversion of the Notes, an
  aggregate of 2,214,669 shares were reserved for issuance pursuant to the
  Company's 1991 Employee Stock Option Plan, and 327,000 shares were reserved
  for issuance pursuant to the Company's 1991 Directors Stock Option Plan.

      Common Stock.  The holders of Common Stock are entitled to one vote for
  each share held of record by them on all matters to be voted on by
  stockholders.  There is no cumulative voting with respect to the election of
  directors; thus, the holders of shares having more than 50% of the Company's
  voting power (including both common and voting preferred shares) voting for
  the election of directors can elect all of the directors.  The holders of
  Common Stock are entitled to receive dividends when, as and if declared by the
  Board of Directors out of funds legally available therefor, subject to the
  prior rights of preferred stockholders.  In the event of liquidation,
  dissolution or a winding up of the Company's affairs, the holders of Common
  Stock are entitled to share ratably in all assets remaining available for
  distribution to them after payment of liabilities and after provision has been
  made for each class of stock, including any preferred stock, that has
  preference over the Common Stock.  Except as described below under "Stock
  Purchase Rights," holders of shares of Common Stock, as such, have no
  conversion, preemptive or other subscription rights, and there are no
  redemption or sinking fund provisions applicable to the Common Stock.  All of
  the outstanding shares of Common Stock are, and the Shares when issued will
  be, validly issued, fully paid and nonassessable.

      The Company currently intends to retain earnings to provide funds for the
  operation and expansion of its business and accordingly does not anticipate
  paying cash dividends on the Common Stock in the foreseeable future.  Any
  payment of cash dividends on the Common Stock in the future will depend upon
  the Company's financial condition, earnings, capital requirements and such
  other factors as the Board of Directors deems relevant.  Dividends on the
  Common Stock are subject to the prior payment of dividends on the Series A
  Preferred Stock.  In addition, under the Company's credit agreement with The
  First

                                      23.
<PAGE>
  
  National Bank of Boston and First Interstate Bank of California, no dividends
  may be paid on the Common Stock without the consent of those banks.

      Preferred Stock.  Shares of preferred stock may be issued without
  stockholder approval.  The Board of Directors is authorized to issue such
  shares in one or more series and to fix the rights, preferences, privileges,
  qualifications, limitations and restrictions thereof, including dividend
  rights and rates, conversion rights, voting rights, terms of redemption,
  redemption prices, liquidation preferences and the number of shares
  constituting any series or the designation of such series, without any vote or
  action by the stockholders.  The Company has no current plans for the issuance
  of any additional shares of preferred stock.  Any preferred stock to be issued
  could rank prior to the Common Stock with respect to dividend rights and
  rights on liquidation.  The Board of Directors, without stockholder approval,
  may issue preferred stock with voting and conversion rights that could
  adversely affect the voting power of holders of Common Stock or create
  impediments to persons seeking to gain control of the Company.

      Series A Preferred Stock.  Each share of Series A Preferred Stock is
  currently convertible into 1.5 shares of Common Stock subject to certain
  events, and votes together with the Common Stock on an "as converted" basis,
  except with respect to certain actions for which the Series A Preferred Stock
  is entitled to vote as a class.  The Series A Preferred Stock automatically
  converts into Common Stock if the closing price of the Common Stock is at
  least 150% of an amount equal to $25.00 divided by the number of shares into
  which each share is convertible at that time.  A cumulative dividend is
  payable on the Series A Preferred Stock at the rate of $.812 per share
  annually, subject to adjustment under certain circumstances.  The Series A
  Preferred Stock has a preference in liquidation over holders of common stock
  of $25 per share plus accrued dividends.  The Company, at its option, may
  redeem shares of the Series A Preferred Stock, subject to certain conditions,
  at a price of $30 per share (and, under certain circumstances, at a price of
  $25.00 per share) plus accrued dividends.  Reacquired or redeemed shares are
  required to be retired and cancelled.

      Stock Purchase Rights.  Eastern Associated Securities Corporation
  (collectively with its affiliates, including Eastern Enterprises, "Eastern"),
  which currently hold 3,041,092 shares of Common Stock, Laidlaw Inc. and its
  affiliates ("Laidlaw"), which currently hold 2,965,829 shares of Common Stock,
  and Aluminum Company of America, which currently holds 880,000 shares of
  Series A Preferred Stock, have certain rights to purchase voting securities of
  the Company in order to maintain their respective percentage voting interests.
  Except in connection with mergers or other acquisitions or in the ordinary
  course under an employee stock option or stock bonus plan, in the event the
  Company proposes to sell or issue shares of voting securities, each of these
  holders has the right to purchase, on the same terms as the proposed sale or
  issuance, that number of shares or rights as will maintain such holder's
  percentage interest in the voting securities of the Company, assuming the
  conversion of all convertible securities and the exercise of all options and
  warrants then outstanding.  In addition, these holders have other purchase
  rights with respect to sales or issuances of securities by the Company at
  prices below 85% of current market price at the time of sale or issuance or
  the prevailing customary price for such securities or their equivalent.

      Certain Voting Arrangements.  Pursuant to the agreements whereby the
  Company acquired Ionpure Technologies Corporation and IP Holding Company
  "Ionpure") from Eastern Enterprises in 1993, the Company agreed, so long as
  Eastern owns at least 5% of the Company's voting securities, to nominate J.
  Atwood Ives (or his successor at Eastern) for election to the Board and, so
  long as Eastern owns at least 10% of the Company's voting securities, Eastern
  has the right to designate a second member of the Board.  The Company also
  agreed that Mr. Ives (or his successor) will be a member of the Audit
  Committee of the Board and that, upon request and with the consent of the
  Board, Mr. Ives will also be appointed to the Compensation Committee or any
  other committee of the Board, other than the Nominating Committee.  Pursuant
  to the agreements whereby the Company acquired Smogless S.p.A. ("Smogless") in
  September 1994, the Company agreed, so long as Laidlaw owns at least 5% of the
  Company's voting securities, to nominate a person designated by Laidlaw for
  election to the Board.  In addition, Eastern and Laidlaw agreed to vote all
  shares owned by them for the Board's nominees for election to the Board and on
  all other matters in the same proportion as the votes cast by the other
  holders of voting securities, other than those that relate to any business
  combination or similar transaction involving the Company or any amendment to
  the Company's Certificate of Incorporation or Bylaws.

                                      24.
<PAGE>
  
      Eastern and Laidlaw have also agreed not to (i) solicit proxies in
  opposition to a recommendation of the Board, (ii) join a group for the purpose
  of acquiring, voting or disposing of voting securities of the Company or (iii)
  solicit stockholders for the approval of one or more stockholder proposals.

      Eastern and Laidlaw have each separately agreed not to acquire voting
  securities of the Company during the six-year period following the date of the
  Ionpure acquisition in the case of Eastern or the Smogless acquisition in the
  case of Laidlaw if, after the acquisition, its percentage share of the
  Company's voting power would exceed its percentage share on the date of
  consummation of the Ionpure or the Smogless acquisition, as the case may be,
  except under certain circumstances, including if any person makes (a) an offer
  to acquire voting securities of the Company that would result in such person
  owning 20% or more of the voting power of the Company or (b) a formal proposal
  for a business combination involving control of the Company, which proposal is
  either (i) not withdrawn or terminated or rejected by the Board within 30 days
  after such proposal is made, or (ii) accepted by the Board.

      Certain Charter and Bylaw Provisions.  The Company's Certificate of
  Incorporation (the "Certificate") places certain restrictions on the voting
  rights of a "Related Person," defined therein as any person who directly or
  indirectly owns 5% or more of the outstanding voting stock of the Company.
  The founders and the original directors of the Company are excluded from the
  definition of "Related Persons," as are seven named individuals including
  Richard J. Heckmann, the Chairman of the Board, President and Chief Executive
  Officer of the Company.  These voting restrictions apply in two situations.
  First, the vote of a director who is also a Related Person is not counted in
  the vote of the Board of Directors to call a meeting of stockholders where
  that meeting will consider a proposal made by the Related Person director.
  Second, any amendments to the Certificate that relate to specified Articles
  therein (those dealing with corporate governance, limitation of director
  liability or amendments to the Certificate), in addition to being approved by
  the Board of Directors and a majority of the Company's outstanding voting
  stock, must also be approved by either (i) a majority of directors who are not
  Related Persons, or (ii) the holders of at least 80% of the Company's
  outstanding voting stock, provided that if the change was proposed by or on
  behalf of a Related Person, then approval by the holders of a majority of the
  outstanding voting stock not held by Related Persons is also required.  In
  addition, any amendment to the Company's Bylaws must be approved by one of the
  methods specified in clauses (i) and (ii) in the preceding sentence.

      The Certificate and the Company's Bylaws provide that the Board of
  Directors shall fix the number of directors and that the Board shall be
  divided into three classes, each consisting of one-third of the total number
  of directors (or as nearly as may be possible).  Stockholders may not take
  action by written consent.  Meetings of stockholders may be called only by the
  Board of Directors (or by a majority of its members).  Stockholder proposals,
  including director nominations, may be considered at a meeting only if written
  notice of that proposal is delivered to the Company from 30 to 60 days in
  advance of the meeting, or within ten days after notice of the meeting is
  first given to stockholders.

      Delaware Anti-Takeover Law.  Section 203 of the Delaware General
  Corporation Law ("Section 203") provides, in general, that a stockholder
  acquiring more than 15% of the outstanding voting shares of a corporation
  subject to the statute (an "Interested Stockholder"), but less than 85% of
  such shares, may not engage in certain "Business Combinations" with the
  corporation for a period of three years subsequent to the date on which the
  stockholder became an Interested Stockholder unless (i) prior to such date the
  corporation's board of directors has approved either the Business Combination
  or the transaction in which the stockholder became an Interested Stockholder
  or (ii) the Business Combination is approved by the corporation's board of
  directors and authorized by a vote of at least two-thirds of the outstanding
  voting stock of the corporation not owned by the Interested Stockholder.

      Section 203 defines the term "Business Combination" to encompass a wide
  variety of transactions with or caused by an Interested Stockholder in which
  the Interested Stockholder receives or could receive a benefit on other than a
  pro rata basis with other stockholders, including mergers, certain asset
  sales, certain issuances of additional shares to the Interested Stockholder,
  transactions with the corporation that increase the proportionate interest of
  the Interested Stockholder or transactions in which the Interested Stockholder
  receives certain other benefits.

                                      25.
<PAGE>
  
      These provisions could have the effect of delaying, deferring or
  preventing a change of control of the Company.  The Company's stockholders, by
  adopting an amendment to the Certificate or Bylaws of the Company, may elect
  not to be governed by Section 203, effective twelve months after adoption.
  Neither the Certificate nor the Bylaws of the Company currently excludes the
  Company from the restrictions imposed by Section 203.


                      DESCRIPTION OF CERTAIN INDEBTEDNESS

      The following summarizes the material long-term indebtedness of the
  Company.  At June 30, 1995, the Company's total consolidated long-term debt
  (including current maturities), after giving effect to the exercise of certain
  warrants to purchase Common Stock and related delivery of $45 million of
  Subordinated Notes due 2001 and sale of the Notes and the application of the
  net proceeds therefrom accounted for 41.5 of its total capitalization.  This
  summary does not include a description of the Notes and is not a complete
  description of the indebtedness described.  The description set forth herein
  is qualified in its entirety by reference to the material agreements relating
  to such indebtedness.

      5% Convertible Subordinated Debentures Due 2000.  The Company has
  outstanding $60,000,000 principal amount of 5% Convertible Subordinated
  Debentures due 2000, which are due on October 15, 2000.  Interest on the 5%
  Convertible Subordinated Debentures due 2000 is payable semi-annually.  The 5%
  Convertible Subordinated Debentures due 2000 are redeemable in whole or in
  part at the option of the Company at any time on or after October 25, 1996 at
  a price, expressed as a percentage of the principal amount, ranging from
  102.86% in 1996 to 100.71% in 1999, plus accrued interest.  The 5% Convertible
  Subordinated Debentures due 2000 are unsecured subordinated obligations of the
  Company and will rank pari passu in all respects with other unsecured
  subordinated obligations of the Company, including the Notes.  Upon certain
  changes in control of the Company, holders of the 5% Convertible Subordinated
  Debentures due 2000 have the right to require the Company to repurchase all or
  a portion of their 5% Convertible Subordinated Debentures due 2000 at 100% of
  principal amount plus accrued interest.  The 5% Convertible Subordinated
  Debentures due 2000 are convertible into Common Stock, currently at a
  conversion price of $20.50 per share, subject to adjustment upon the
  occurrence of certain events.  The Company has filed and is maintaining the
  effectiveness of a shelf registration statement covering resales by the
  holders of all 5% Convertible Subordinated Debentures due 2000 and the Common
  Stock issuable upon conversion thereof.


                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

      The following is a summary of certain Federal income tax considerations
  for purchasers of the Notes and is based on the Federal income tax law now in
  effect, which is subject to change, possibly retroactively.  This summary does
  not discuss all aspects of Federal income taxation that may be relevant to
  particular holders of Notes in light of their individual investment
  circumstances or to certain types of investors subject to special tax rules
  (e.g., financial institutions, insurance companies, tax-exempt organizations
  and foreign taxpayers), nor does it discuss any aspects of state, local or
  foreign tax law consequences.  This summary assumes that investors will hold
  their Notes as "capital assets" (generally, property held for investment)
  under the Internal Revenue Code of 1986, as amended.  Prospective purchasers
  are urged to consult their tax advisors regarding the specific Federal, state,
  local and foreign income and other tax consequences of purchasing, holding and
  disposing of the Notes.

  Sale or Exchange

      A holder will recognize capital gain or loss upon the sale or other
  disposition of a Note in an amount equal to the difference between the amount
  realized from such disposition and his tax basis in the Note.  Such gain or
  loss will be long-term if the Note has been held for more than one year.

                                      26.
<PAGE>
  
  Conversion

      A holder's conversion of a Note into Common Stock is generally not a
  taxable event (except with respect to cash received in lieu of a fractional
  share).  The holder's tax basis in the Common Stock received on conversion of
  a Note will be the same as the holder's tax basis in the Note at the time of
  conversion (exclusive of any tax basis allocable to a fractional share), and
  the holding period for the Common Stock received on conversion will include
  the holding period of the Note converted.

  Constructive Dividend

      If at any time the Company makes a distribution of property to
  shareholders that would be taxable to such shareholders as a dividend for
  Federal income tax purposes and, in accordance with the antidilution
  provisions of the Notes, the Conversion Price of the Notes is decreased, the
  amount of such decrease may be deemed to be the payment of a taxable dividend
  to holders.  For example, a decrease in the Conversion Price in the event of
  distributions of evidence of indebtedness or assets of the Company will
  generally result in deemed dividend treatment to holders, but generally a
  decrease in the event of stock dividends or the distribution of rights to
  subscribe for shares will not.  See "Description of the Notes-Conversion
  Rights."


                                 LEGAL MATTERS

      The validity of the securities offered hereby will be passed upon the
  Company by Damian C. Georgino, Vice President and General Counsel of the
  Company.  Mr. Georgino presently holds 100 shares of the Company's Common
  Stock and options granted under the Company's 1991 Employee Stock Option Plan
  to purchase an aggregate of 10,000 shares of the Common Stock.
