                                  THE COMPANY


     Magma is a fully integrated producer of electrolytic copper and ranks among
the largest U.S. copper producers.  Magma's principal  products are high quality
copper  cathode and high  quality  copper rod,  the latter of which is the basic
feedstock of the copper wire and cable industry.

     The Company  owns and operates  underground  copper mines at its San Manuel
and  Superior  Mining  Divisions,  an open-pit  copper mine at its Pinto  Valley
Mining  Division,  and in situ  leaching  operations at its San Manuel and Pinto
Valley  Mining  Divisions,  all of which are  located in  southeastern  Arizona.
Recently,  the Company began  development of its Robinson mine located near Ely,
Nevada.  Production at this mine is expected to commence in the first quarter of
1996. In the fourth quarter of 1994, the Company  completed the acquisition of a
company  which  owns  one  of the  largest  operating  mines  in  Southern  Peru
("Tintaya").  Tintaya  operates an open-pit  mine and is engaged in a variety of
development projects at this property.

     The  Company  operates  the largest and most  modern  copper  smelting  and
refining complex in the United States. The Company's smelter, which was expanded
in 1994, has a rated  production  capacity of 720 million pounds of copper anode
per year,  representing  approximately 25% of U.S. copper smelting capacity.  In
addition to smelting  and refining its own copper  concentrate  production,  the
Company  smelts and refines a  substantial  amount of copper  concentrates  on a
custom  basis for, or  purchased  from,  third  parties,  the profits from which
effectively  reduce the Company's  overall  break-even cost of producing  copper
from its mines.

                           INVESTMENT CONSIDERATIONS

     Copper Price Volatility.  The profitability of the Company's  operations is
largely  dependent  upon the worldwide  market price for copper.  A one cent per
pound change in the average price  received for the Company's  1994 output would
have affected earnings before interest,  taxes, depreciation and amortization by
an estimated $6.0 million.  Copper prices have historically been subject to wide
fluctuations  and are  affected  by numerous  factors  beyond the control of the
Company,  including  international economic and political conditions,  levels of
supply and demand,  the availability and cost of copper  substitutes,  inventory
levels  maintained  by copper  producers  and others  and,  to a lesser  degree,
inventory carrying costs (primarily interest charges) and international exchange
rates. From time to time the Company engages in hedging  activities in an effort
to stabilize the Company's  cash flow in the event of declining  copper  prices.
Depending  upon the  hedging  program  employed,  market  conditions  and  other
factors,  hedging  activities could reduce the cash flow which the Company would
otherwise realize.

     Competition.  Certain  foreign and domestic copper  producers  benefit from
higher-grade  orebodies than those owned by the Company.  Further,  most foreign
producers  benefit  from  lower  labor  rates and less  stringent  environmental
regulation than United States producers. Many foreign producers maintain maximum
production to meet  government-imposed  employment and foreign  exchange revenue
goals,  sometimes  without regard to the condition of the world copper market or
the  profitability  of their  mining  operations.  The Company and other  copper
producers  also  compete  with  manufacturers  of  other  materials,   including
aluminum, stainless steel, plastics and fiber optic cables. Should copper prices
increase, use of these alternative materials may also increase.

     Environmental Regulation.  The mining and mineral processing industries are
subject  to  extensive  regulations  for  the  protection  of  the  environment,
including  regulations  relating  to air and water  quality,  mine  reclamation,
remediation,  solid and hazardous  waste handling and disposal and the promotion
of occupational safety. From time to time the Company is cited for noncompliance
with  applicable  environmental  laws  and  regulations.  However,  the  Company
believes  that it is  currently  in  material  compliance  with  these  laws and
regulations  and,  although  there  can be no  assurance  in this  regard,  also
believes that there is no pending  environmental matter that is likely to have a
material  adverse  effect on its results of  operations.  Future  regulations or
regulatory  interpretations  could  require the Company to modify or curtail its
operations or incur substantial  additional expense. In this regard, the Company
cannot  predict,  at this time, the level of new emissions  controls and related
costs which may be required for it to comply with standards  governing emissions
of sulphur,  particulates  and air toxics that are expected to be adopted  under
the federal Clean Air Act Amendments of 1990 and the Arizona Clean Air Act.

     Industry  Risks;  Reserves.  The  Company is  subject  to the normal  risks
encountered  in the mining  industry,  such as unusual or unexpected  geological
formations,  cave-ins,  flooding, fires,  environmental issues and water issues.
The Company's  mineral  reserves may not conform to  geological,  geomechanical,
metallurgical or other expectations with the result that the volume and grade of
reserves  recovered  and  rates  of  production  may be less  than  anticipated.
Further,  market price fluctuations in copper,  changes in operating and capital
costs and other factors may affect ore reserves.

     Development  Projects.  The  Company  is  pursuing  or  evaluating  several
development opportunities in an effort to enhance its ore reserves.  Development
of these  projects  will  require  several  hundred  million  dollars in capital
investment.  To the extent  undertaken,  the  Company  intends  to  finance  its
development  projects  with internal  cash flow,  cash  reserves and  additional
financings as necessary. The success of these projects is subject to a number of
factors,  some of which are outside of the Company's control. The cost estimates
for these  projects  are subject to change.  If the Company is unable to replace
its reserves from the mine development  projects being pursued or evaluated,  or
with  other  reserves  identified  or  acquired  in the  future,  the  Company's
dependence upon third-party sources to supply copper concentrate to its smelting
and refining operations would increase.

     Investments  in Foreign  Mining  Properties.  The  Company is engaged in an
ongoing  program  of  reviewing   exploratory   and  operating   properties  for
acquisition or development.  Many of these properties are located outside of the
United States. There are certain risks inherent in the acquisition and operation
of  foreign  properties,  including  the  risks of  political  instability,  the
possibility of adverse economic or tax reforms, restrictions on the repatriation
of funds,  and  currency  risks.  In the  fourth  quarter of 1994,  the  Company
acquired Magma Tintaya S. A. (formerly known as Empressa Minera Especial Tintaya
S.A.),  which  owns one of the  largest  operating  copper  mining  projects  in
Southern  Peru.  As part of its  investment  in  Tintaya,  the  Company  and the
government of Peru entered into a judicial  stability  agreement and the Company
became a party to an existing tax stability agreement between the government and
Tintaya.  These  agreements  provide for,  among other things,  free exchange of
foreign currency,  remittance abroad of profits and capital, the right to use or
sell any product  derived from Tintaya,  and tax and legal  stability.  Although
these  agreements do not eliminate all risk  associated  with its  investment in
Tintaya,  the Company  believes  that such  agreements  minimize a number of the
risks typically associated with an investment in a foreign property.

                                USE OF PROCEEDS

     The  Company  anticipates  that  the  net  proceeds  of  the  sales  of the
Securities will be used for general corporate purposes or such other uses as may
be set forth in a Prospectus Supplement.


         RATIO OF EARNINGS TO FIXED CHARGES AND EARNINGS TO COMBINED
           FIXED CHARGES AND PREFERRED STOCK DIVIDEND REQUIREMENTS

     For purposes of the  following  ratios:  (i)  "earnings"  consist of income
before  taxes,  accounting  changes and  extraordinary  items plus fixed charges
adjusted for capitalized  interest and  amortization  of previously  capitalized
interest;  (ii)  "fixed  charges"  consist of  interest  (including  capitalized
interest)  and  the  estimated   interest  portion  of  lease  rental  expenses,
amortization of debt expenses and write-offs of loan costs; and (iii) "preferred
stock  dividend  requirements"  include  dividends paid in zero coupon notes and
shares of Common Stock.

     In  calculating  the  ratio of  earnings  to  combined  fixed  charges  and
preferred stock dividend requirements, the preferred stock dividend requirements
were assumed to be equal to the pretax earnings  required to cover such dividend
requirements.  The amount of such pretax  earnings  required to cover  preferred
stock dividends was computed using tax rates for the applicable year.  Preferred
stock  dividends  are  included  in total  "fixed  charges"  and  deducted  from
"earnings."

     Before giving effect to the non-cash  accounting  adjustments taken in 1991
in connection with the Company's reorganization into distinct profit centers and
the related  adoption of FASB No. 109 "Accounting for Income Taxes" and FASB No.
106 "Employers' Accounting for Postretirement Benefits Other Than Pensions," the
ratio of earnings to fixed charges for the year ended December 31, 1991 was 1.8x
and the ratio of earnings to combined fixed charges and preferred stock dividend
requirements  for that year was 1.5x.  After  giving  effect to such  accounting
adjustments,  earnings were  inadequate to cover fixed charges by $167.5 million
for the year ended December 31, 1991 and were inadequate to cover combined fixed
charges and preferred  stock  dividend  requirements  by $179.8 million for that
year.


                         DESCRIPTION OF DEBT SECURITIES


     The Debt  Securities  may be issued from time to time in one or more series
and will constitute  either Senior Debt  Securities,  Senior  Subordinated  Debt
Securities or Subordinated Debt Securities.  The particular terms of each series
of Debt  Securities  offered  hereunder,  including the nature of any variations
from the following general provisions  applicable to such Debt Securities,  will
be described in a Prospectus Supplement relating to such Debt Securities. Senior
Debt  Securities,  Senior  Subordinated  Debt Securities and  Subordinated  Debt
Securities will each be issued under a separate Indenture (herein referred to as
the  "Senior  Indenture",  "Senior  Subordinated  Indenture"  and  "Subordinated
Indenture",  respectively;  and individually an "Indenture" and collectively the
"Indentures")  entered  into by the Company  prior to the  issuance of such Debt
Securities.  The forms of Senior  Indenture and  Subordinated  Indenture and the
Senior Subordinated Indenture, dated as of May 15, 1995, between the Company and
State Street Bank and Trust Company, as Trustee,  have been filed as exhibits to
or have been incorporated by reference into the Registration  Statement to which
this  Prospectus  relates.  To  the  extent  not  included  herein,  information
regarding  the  trustee  under  an  Indenture   (individually  a  "Trustee"  and
collectively  the  "Trustees")  will be  included in the  applicable  Prospectus
Supplement relating to the Debt Securities described therein.

     The following  discussion  includes a summary  description  of the material
terms of the  Indentures,  other than terms which are  specific to a  particular
series  of Debt  Securities  and  which  will  be  described  in the  Prospectus
Supplement relating to such series. The following summaries do not purport to be
complete and are subject to, and are  qualified  in their  entirety by reference
to, all of the provisions of the Indentures,  including the definitions  therein
of certain terms capitalized in this Prospectus.  Wherever particular  Sections,
Articles  or defined  terms of the  Indentures  are  referred  to herein or in a
Prospectus Supplement, such Sections, Articles or defined terms are incorporated
herein or therein by reference.

General

     The Debt Securities will be general  unsecured  obligations of the Company.
The Indentures do not limit the aggregate amount of Debt Securities which may be
issued  thereunder,  and Debt  Securities may be issued  thereunder from time to
time in separate series up to the aggregate  amount from time to time authorized
by the Company for each series.

     The  applicable  Prospectus  Supplement  or  Prospectus   Supplements  will
describe  the  following  terms of the series of Debt  Securities  in respect of
which this Prospectus is being delivered: (1) the title of such Debt Securities,
and whether such Debt Securities are Senior Debt Securities, Senior Subordinated
Debt Securities or Subordinated Debt Securities;  (2) any limit on the aggregate
principal  amount  of  such  Debt  Securities;  (3)  whether  any of  such  Debt
Securities are to be issuable in permanent global form ("Global  Security") and,
if so, the terms and conditions, if any, upon which interests in such Securities
in global form may be exchanged,  in whole or in part, for the  individual  Debt
Securities  represented thereby; (4) the person to whom any interest on any Debt
Security  of the series  shall be payable if other than the person in whose name
the Debt  Security is  registered  on the Regular  Record Date;  (5) the date or
dates on which such Debt  Securities  will mature;  (6) the rate or rates (which
may be fixed or  variable)  of  interest,  if any, or the method of  calculation
thereof,  which such Debt Securities will bear; (7) the date or dates from which
any such  interest  will accrue,  the Interest  Payment  Dates on which any such
interest on such Debt Securities will be payable and the Regular Record Date for
any interest payable on any Interest Payment Date; (8) the place or places where
the principal of, premium,  if any, and interest on such Debt Securities will be
payable;  (9) the period or periods within which, the events upon the occurrence
of which, and the price or prices at which,  such Debt Securities may,  pursuant
to any optional or mandatory provisions,  be redeemed or purchased,  in whole or
in part, by the Company and any terms and conditions relevant thereto;  (10) the
obligations of the Company, if any, to redeem or repurchase such Debt Securities
at the  option of the  holders;  (11) the  denominations  in which any such Debt
Securities  will be  issuable,  if other  than  denominations  of $1,000 and any
integral  multiple  thereof;  (12) the currency,  currencies or currency unit or
units of payment of  principal  of and any  premium  and  interest  on such Debt
Securities  if other  than  U.S.  dollars;  (13) any  index or  formula  used to
determine the amount of payments of principal of and any premium and interest on
such Debt Securities;  (14) if the principal of, or premium, if any, or interest
on such Debt  Securities  is to be payable,  at the election of the Company or a
holder  thereof,  in one or more currencies or currency units other than that or
those in which such Debt  Securities  are stated to be  payable,  the  currency,
currencies  or  currency  units in which  payment  of the  principal  of and any
premium and interest on Debt Securities of such series as to which such election
is made  shall be  payable,  and the  periods  within  which  and the  terms and
conditions  upon  which  such  election  is to be made;  (15) if other  than the
principal  amount  thereof,  the  portion of the  principal  amount of such Debt
Securities of the series which will be payable upon acceleration of the Maturity
thereof;  (16)  whether  the  subordination   provisions  summarized  below,  or
different  subordination  provisions,  shall apply to Debt  Securities  that are
Senior  Subordinated Debt Securities or Subordinated Debt Securities and, if so,
the aggregate principal amount of Senior Indebtedness then outstanding; (17) the
applicability  of any  provisions  described  under  "Covenants  with Respect to
Senior Debt Securities" or "Covenants with Respect to Senior  Subordinated  Debt
Securities";   (18)  the   applicability  of  any  provisions   described  under
"Defeasance";  (19) the terms and conditions, if any, pursuant to which the Debt
Securities  are  convertible  or   exchangeable   into  Common  Stock  or  other
Securities;  and (20) any other terms of such Debt  Securities not  inconsistent
with the provisions of the respective Indentures.

     Debt  Securities may be issued at a discount from their  principal  amount.
United States Federal income tax considerations and other special considerations
applicable to any such Original Issue Discount  Securities  will be described in
the applicable Prospectus Supplement.

     If the purchase  price of any of the Debt  Securities is  denominated  in a
foreign  currency or  currencies  or a foreign  currency unit or units or if the
principal  of and any premium and interest on any series of Debt  Securities  is
payable in a foreign currency or currencies or a foreign currency unit or units,
the  restrictions,  elections,  general tax  considerations,  specific terms and
other  information  with  respect to such issue of Debt  Securities  will be set
forth in the applicable Prospectus Supplement.

     The Indentures do not limit the amount of additional unsecured indebtedness
that  the  Company  or its  subsidiaries  may  incur.  Further,  certain  of the
operations  of the  Company  are  and may in the  future  be  conducted  through
subsidiaries. To the extent so conducted, the ability of the Company to meet its
debt obligations, including obligations in respect of the Debt Securities, would
be dependent upon the earnings and cash flow of its subsidiaries, and the claims
of the holders of the Debt  Securities  will be effectively  subordinated to the
claims of creditors of the Company's subsidiaries.

     Unless otherwise specified in the resolutions or any supplemental indenture
establishing the terms of the offered Debt Securities,  the terms of the offered
Debt  Securities  or the  covenants  contained  in the  Indenture  do not afford
holders  protection  in  the  event  of a  highly  leveraged  or  other  similar
transaction involving the Company that may adversely affect securityholders.

Subordination of  Senior Subordinated Debt Securities  and Subordinated Debt
Securities

     The term  "Senior  Indebtedness",  when used with  respect to any series of
Senior  Subordinated  Debt  Securities,  means  indebtedness  of the Company and
indebtedness guaranteed by the Company for principal of and premium and interest
on  (a)  money  borrowed  from  banks  or  other  lending  institutions  whether
outstanding on the date of the initial issuance of any Senior  Subordinated Debt
Securities or thereafter  incurred and (b) any other  indebtedness or obligation
of the Company,  whether  outstanding on the date of the initial issuance of any
Senior Subordinated Debt Securities or thereafter created,  incurred, assumed or
guaranteed, which is evidenced by a note or other similar instrument,  including
Senior Debt Securities,  unless by the terms of such note or other instrument it
is provided  that such  indebtedness  is not superior in right of payment to the
Senior Subordinated Debt Securities; provided, however, that Senior Indebtedness
shall not include (w) any other series of Senior  Subordinated  Debt Securities,
(x) any trade  payables or notes or other  instruments  evidencing the same, (y)
notes or other  obligations  issued in lieu of cash dividends on, or in exchange
for,  Capital  Stock,  or (z) any liability for federal,  state,  local or other
taxes  owed or  owing  by the  Company.  At  June  12,  1995,  the  Company  had
outstanding  three  series  of  Senior  Subordinated  Debt  Securities,  with an
aggregate principal amount outstanding of $525,000,000.

     The term  "Senior  Indebtedness",  when used with  respect to any series of
Subordinated Debt Securities, means indebtedness of the Company and indebtedness
guaranteed by the Company for principal of and premium and interest on (a) money
borrowed from banks or other lending  institutions  whether  outstanding  on the
date of the initial issuance of any  Subordinated  Debt Securities or thereafter
incurred and (b) any other  indebtedness  or obligation of the Company,  whether
outstanding  on the  date  of the  initial  issuance  of any  Subordinated  Debt
Securities or thereafter  created,  incurred,  assumed or  guaranteed,  which is
evidenced  by  a  note  or  other  similar  instrument,  including  Senior  Debt
Securities and Senior Subordinated Debt Securities,  unless by the terms of such
note or other  instrument it is provided that such  indebtedness is not superior
in right of payment to the Subordinated Debt Securities; provided, however, that
Senior  Indebtedness shall not include (w) any other series of Subordinated Debt
Securities,  (x) any trade payables or notes or other instruments evidencing the
same, (y) notes or other obligations  issued in lieu of cash dividends on, or in
exchange for, Capital Stock, or (z) any liability for federal,  state,  local or
other taxes owed or owing by the Company.

     In  either  case,  the  term  "Senior   Indebtedness"   includes,   without
limitation,  (i) any and all interest accruing on any of the Senior Indebtedness
after the commencement of any bankruptcy,  insolvency,  reorganization  or other
similar  proceeding,  notwithstanding  any  provision or rule of law which might
restrict the rights of any holder thereof as to such interest,  and (ii) any and
all claims for principal  of,  premium and interest on, and fees and expenses in
respect of, Senior Indebtedness  described in clause (a) above,  notwithstanding
any disallowance, avoidance or subordination of such claim under any insolvency,
fraudulent conveyance or equitable subordination law.

     Payment of the principal amount of and premium, if any, and interest on the
Senior   Subordinated   Debt  Securities  and   Subordinated   Debt  Securities,
respectively,  will be  subordinated in right of payment to the prior payment in
full of all Senior Indebtedness with respect thereto on the terms and conditions
of the respective  Indentures governing such Senior Subordinated Debt Securities
and Subordinated Debt Securities,  respectively.  The Company is prohibited from
making any payment of principal of or premium or interest on Senior Subordinated
Debt Securities or  Subordinated  Debt  Securities,  as the case may be, and any
payment in respect of any redemption,  retirement, purchase or other acquisition
of Senior  Subordinated Debt Securities or Subordinated Debt Securities,  as the
case may be, (i) unless,  as of the earlier to occur of the date such payment is
made and the date that provision is made for such payment in accordance with the
terms  of the  applicable  Indenture,  all  amounts  then  due and  payable  for
principal of and  premium,  if any,  and  interest on Senior  Indebtedness  with
respect  to  the  Senior  Subordinated  Debt  Securities  or  Subordinated  Debt
Securities,  as the  case may be,  have  been  paid in  full,  or (ii) if at the
earlier to occur of the date of such  payment or provision  therefor,  there has
occurred  any  event of  default  under the  terms of such  Senior  Indebtedness
entitling  the holder of such Senior  Indebtedness  to  accelerate  the maturity
thereof as a result of such event of default.  Notwithstanding such prohibition,
the  Company  may make such  payments,  if (a) the  Company or the  Trustee  has
received  a notice  of a default  or an event of  default  under  any  agreement
covering  such Senior  Indebtedness  (other than notice of a default or event of
default relating to payments of principal or interest,  either at maturity, upon
redemption,  by  declaration  or  otherwise),  which default or event of default
would permit the holders of such Senior  Indebtedness to accelerate its maturity
(whether or not such  acceleration  has occurred),  and (b) 179 days have passed
after the  earliest  date on which such  notice  was given with  respect to such
default  or  event of  default  (a  "Payment  Blockage  Period")  so long as the
applicable Indenture otherwise permits payment at that time; provided,  however,
that only one Payment Blockage Period may be commenced within one 360-day period
with respect to the Senior  Subordinated  Debt Securities or  Subordinated  Debt
Securities,  as the  case  may be.  No event of  default  which  existed  or was
continuing on the date of the  commencement of any Payment  Blockage Period with
respect  to the  Senior  Indebtedness  shall be,  or be made,  the basis for the
commencement of a second Payment Blockage Period by the  representative  for the
holders of such Senior Indebtedness unless such event of default shall have been
cured or  waived  for a period of not less than 90  consecutive  days.  (Article
Fifteen of Senior Subordinated Indenture and Subordinated Indenture)

     Upon any payment or  distribution of assets or securities of the Company of
any kind or character upon any dissolution,  winding up or total  liquidation or
reorganization  of the  Company (in  bankruptcy  or  otherwise),  the holders of
Senior  Indebtedness with respect to the Senior  Subordinated Debt Securities or
Subordinated  Debt  Securities,  as the case may be,  will first be  entitled to
receive  payment in full of principal  of and  premium,  if any, and interest on
such  Senior  Indebtedness  before  the  holders  of  Senior  Subordinated  Debt
Securities or Subordinated Debt Securities,  as the case may be, are entitled to
receive  any payment of the  principal  of or premium or interest on such Senior
Subordinated  Debt Securities or Subordinated  Debt Securities,  as the case may
be.  (Article  Fifteen  of  Senior   Subordinated   Indenture  and  Subordinated
Indenture)

     By reason of such provisions, in the event of insolvency, holders of Senior
Subordinated  Debt Securities and Subordinated Debt Securities may recover less,
ratably, than holders of Senior Indebtedness with respect
thereto.

     The Senior Debt  Securities,  when  issued,  will rank on a parity with all
other unsecured and unsubordinated indebtedness of the Company.

Conversion or Exchange of Debt Securities

     If so indicated in the applicable  Prospectus  Supplement with respect to a
particular  series  of Debt  Securities,  such  series  will be  convertible  or
exchangeable  into Common Stock or other  securities on the terms and conditions
set forth therein.

Form, Exchange, Registration, Conversion, Transfer and Payment

     Unless otherwise  indicated in the applicable  Prospectus  Supplement,  the
Debt Securities will be issued only in fully registered form in denominations of
$1,000 or integral multiples thereof.  (Section 302) Unless otherwise  indicated
in the applicable  Prospectus  Supplement,  payment of principal of, premium, if
any,  and interest on the Debt  Securities  will be payable,  and the  exchange,
conversion and transfer of Debt Securities will be  registerable,  at the office
or agency of the Company maintained for such purposes and at any other office or
agency  maintained  for such  purpose.  (Sections  301, 305 and 1002) No service
charge  will be made for any  registration  of  transfer or exchange of the Debt
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge imposed in connection therewith. (Section 305)

     All  monies  paid by the  Company  to a paying  agent  for the  payment  of
principal  of and any  premium or  interest on any Debt  Security  which  remain
unclaimed for two years after such principal, premium or interest has become due
and payable may be repaid to the Company and  thereafter the holder of such Debt
Security may look only to the Company for payment thereof.
(Section 1003)

Global Securities

     The Debt  Securities  of a series  may be issued in whole or in part in the
form of one or more Global  Securities that will be deposited with, or on behalf
of,  a  Depositary  ("Global  Depositary")  or  its  nominee  identified  in the
applicable Prospectus Supplement.  In such a case, one or more Global Securities
will be issued in a denomination or aggregate  denomination equal to the portion
of the aggregate  principal  amount of outstanding Debt Securities of the series
to be represented by such Global Security or Securities.  Unless and until it is
exchanged in whole or in part for Debt  Securities in registered  form, a Global
Security may not be registered for transfer or exchange except as a whole by the
Global  Depositary  for  such  Global  Security  to a  nominee  of  such  Global
Depositary or by a nominee of such Global  Depositary to such Global  Depositary
or another nominee of such Global Depositary or by such Global Depositary or any
nominee to a successor  Global  Depositary or a nominee of such successor Global
Depositary  and  except  in  the  circumstances   described  in  the  applicable
Prospectus Supplement. (Sections 204 and 305)

     The  specific  terms of the  depositary  arrangement  with  respect  to any
portion of a series of Debt  Securities to be represented  by a Global  Security
will be described in the applicable Prospectus  Supplement.  The Company expects
that the following provisions will apply to depositary arrangements.

     Unless otherwise specified in the applicable  Prospectus  Supplement,  Debt
Securities which are to be represented by a Global Security to be deposited with
or on behalf of a Global  Depositary  will be represented  by a Global  Security
registered  in the  name of such  Global  Depositary  or its  nominee.  Upon the
issuance of such Global  Security,  and the deposit of such Global Security with
or on behalf of the  Global  Depositary  for such  Global  Security,  the Global
Depositary will credit, on its book-entry  registration and transfer system, the
respective  principal amounts of the Debt Securities  represented by such Global
Security to the accounts of  institutions  that have  accounts  with such Global
Depositary or its nominee ("participants").  The accounts to be credited will be
designated  by the  underwriters  or agents of such  Debt  Securities  or by the
Company,  if such Debt  Securities are offered and sold directly by the Company.
Ownership  of  beneficial  interest in such Global  Security  will be limited to
participants or Persons that may hold interests through participants.  Ownership
of beneficial  interests by  participants  in such Global Security will be shown
on, and the transfer of that  ownership  interest will be effected only through,
records  maintained  by the Global  Depositary  or its  nominee  for such Global
Security.  Ownership of beneficial  interests in such Global Security by Persons
that hold  through  participants  will be shown  on,  and the  transfer  of that
ownership  interest  within  such  participant  will be effected  only  through,
records maintained by such participant.  The laws of some jurisdictions  require
that certain  purchasers of securities take physical delivery of such securities
in  certificated  form. The foregoing  limitations  and such laws may impair the
ability to transfer beneficial interests in such Global Securities.

     So long as the Global Depositary for a Global Security,  or its nominee, is
the registered  owner of such Global  Security,  such Global  Depositary or such
nominee,  as the case may be, will be considered the sole owner or holder of the
Securities  represented  by such  Global  Security  for all  purposes  under the
applicable  Indenture.  Unless otherwise specified in the applicable  Prospectus
Supplement,  owners of beneficial  interests in such Global Security will not be
entitled  to have Debt  Securities  of the  series  represented  by such  Global
Security  registered in their names,  will not receive or be entitled to receive
physical  delivery of Debt  Securities of such series in  certificated  form and
will not be considered the holders thereof for any purposes under the applicable
Indenture.  (Sections 204 and 305) Accordingly,  each Person owning a beneficial
interest  in such  Global  Security  must rely on the  procedures  of the Global
Depositary  and, if such Person is not a  participant,  on the procedures of the
participant through which such Person owns its interest,  to exercise any rights
of a holder under the applicable  Indenture.  The Company understands that under
existing industry practices, if the Company requests any action of holders or an
owner of a  beneficial  interest  in such  Global  Security  desires to give any
notice  or take  any  action  a  holder  is  entitled  to give or take  under an
Indenture,  the Global  Depositary would authorize the participants to give such
notice or take such action, and participants  would authorize  beneficial owners
owning  through  such  participants  to give such  notice or take such action or
would otherwise act upon the  instructions  of beneficial  owners owning through
them.

     Principal  of and any premium and  interest  on a Global  Security  will be
payable in the manner described in the applicable Prospectus Supplement.

Covenants with Respect to Senior Debt Securities

     If so indicated in the applicable  Prospectus  Supplement with respect to a
particular  series  of Senior  Debt  Securities,  holders  of such  Senior  Debt
Securities  will be  entitled  to the  benefit  of one or both of the  following
covenants.

     Restrictions on Secured Debt

     Neither  the Company  nor any  Subsidiary  shall  incur,  issue,  assume or
guarantee any notes,  bonds,  debentures or other evidences of indebtedness  for
money  borrowed  (collectively,  "Debt")  secured  after the date of the  Senior
Indenture by a mortgage,  pledge or lien ("Mortgage") on any Principal  Property
of the Company or a Significant  Subsidiary or on any shares of stock or Debt of
any  Significant  Subsidiary,   unless  the  Company  secures,  or  causes  such
Significant Subsidiary to secure, the Senior Debt Securities equally and ratably
with (or, at the Company's option, prior to) such secured Debt, together, at the
determination of the Company, with certain other Debt of the Company;  provided,
however,  that such restriction shall not apply to the incurrence of any secured
Debt if, after giving effect thereto, the aggregate outstanding principal amount
of all such Debt so  secured  after the date of the Senior  Indenture,  together
with all  Attributable  Debt of the Company and its Significant  Subsidiaries in
respect  of sale  and  leaseback  transactions  after  the  date  of the  Senior
Indenture and existing at such time involving Principal  Properties owned by the
Company or a Significant  Subsidiary  (with the  exception of such  transactions
which are  excluded  as  described  in  "Restrictions  on Sales and  Leasebacks"
below),  would not exceed 10% of the Consolidated  Assets of the Company and its
Subsidiaries.

     This  restriction  will not  apply  to,  and  there  shall be  excluded  in

development cost thereof, or any Debt incurred in connection therewith, existing
prior to, at the time of, or within 180 days after,  the acquisition  (including
any acquisition through merger or consolidation) or construction, improvement or
development  thereof,  provided that any such Mortgage  shall only extend to the
property,  equipment,  mines or facilities, or shares of stock or Debt, acquired
or  constructed,  improved or  developed,  or to  property  or mines,  including
undeveloped  mineralized deposits or orebodies or segments thereof, on which the

any Mortgage  referred to in the  foregoing  clauses (a) through (g)  inclusive.
(Section 1006 of Senior  Indenture)  The Senior  Indenture does not restrict the
Company or any Subsidiary from incurring unsecured Debt.

     Restrictions on Sales and Leasebacks

     Neither the Company nor any Significant  Subsidiary may enter into any sale
and leaseback transaction involving any Principal Property,  unless after giving
effect thereto the aggregate amount of all Attributable Debt with respect to all
such transactions  occurring after the date of the Senior Indenture and existing
at such time plus all  outstanding  secured Debt incurred by the Company and its
Significant  Subsidiaries  after  the date of the  Senior  Indenture  (with  the
exception of secured Debt which is excluded as  described  in  "Restrictions  on
Secured Debt" above) would not exceed 10% of Consolidated  Assets of the Company
and its Subsidiaries.

     This  restriction  does not apply  to,  and there  shall be  excluded  from
Attributable  Debt in any  computation  under  such  restriction,  any  sale and
leaseback  transaction  if (a) the  lease  is for a  period,  including  renewal
rights,  not in excess of three years; (b) the sale or transfer of the Principal
Property  is made  prior  to,  at the time of,  or  within  180 days  after  its
acquisition or completion of  construction;  (c) the lease secures or relates to
certain  tax-exempt   obligations  issued  by  governmental  bodies,   including
industrial  revenue or pollution  control bonds;  (d) the transaction is between
the Company and a Significant  Subsidiary or between  Significant  Subsidiaries;
(e) the  lease  payment  obligation  is  created  in  connection  with a project
financed,  or  assets  acquired,  with,  and  such  obligation  constitutes,   a
Nonrecourse  Obligation;  or (f) the  Company  or such  Significant  Subsidiary,
within 180 days after the sale is completed, applies to the retirement of Funded
Debt of the Company or a  Significant  Subsidiary,  or to the  purchase of other
property which will constitute  Principal Property,  an amount not less than the
greater of (i) the net proceeds of the sale of the Principal  Property leased or
(ii) the fair market value of the Principal  Property  leased,  as determined by
certain  officers of the Company.  The amount to be applied to the retirement of
Funded  Debt  shall be reduced by (x) the  principal  amount of any Funded  Debt
(including  the Debt  Securities)  of the  Company or a  Significant  Subsidiary
retired and cancelled  within 180 days after such sale with proceeds  other than
the proceeds from such sale and (y) the principal  amount of Funded Debt,  other
than any Funded  Debt  referred  to in the  preceding  clause  (x),  voluntarily
retired by the Company or any Significant  Subsidiary within 180 days after such
sale using  proceeds  other than the  proceeds  of such sale.  (Section  1007 of
Senior Indenture)

Covenants with Respect to Senior Subordinated Debt Securities

     If so indicated in the applicable  Prospectus  Supplement with respect to a
particular series of Senior Subordinated Debt Securities, holders of such Senior
Subordinated  Debt  Securities will be entitled to the benefit of one or both of
the following covenants.

     Limitation on Subordinated Liens

     Neither  the Company  nor any  Subsidiary  shall  incur,  issue,  assume or
guarantee  any  Debt  which  is pari  passu or (by the  express  terms  thereof)
subordinate  in right of  payment to the Senior  Subordinated  Debt  Securities,
secured after the date of the Senior Subordinated Indenture by a Mortgage on any
Principal  Property of the Company or a Significant  Subsidiary or on any shares
of stock or Debt of any Significant  Subsidiary,  unless the Company secures, or
causes such  Significant  Subsidiary  to secure,  the Senior  Subordinated  Debt
Securities (i) equally and ratably with (or, at the Company's option,  prior to)
such  secured Debt or (ii) in the event such  secured  Debt is  subordinated  in
right to payment to the Senior  Subordinated  Securities,  prior to such secured
Debt, together,  at the determination of the Company, with certain other Debt of
the Company;  provided,  however,  that such restriction  shall not apply to the
incurrence  of any secured Debt if, after giving effect  thereto,  the aggregate
amount of all such Debt so  secured  after the date of the  Senior  Subordinated
Indenture and then outstanding  would not exceed 10% of the Consolidated  Assets
of the Company and its Subsidiaries.

     This  restriction  will not  apply  to,  and  there  shall be  excluded  in
computing secured Debt for the purpose of such  restriction,  Debt secured prior
to the  date of the  Senior  Subordinated  Indenture  and  Debt  secured  by (a)

(c) Mortgages in favor of  governmental  bodies to secure  progress,  advance or

property,  equipment, mines or facilities, or shares of stock or Debt, to secure
the  payment  of  all  or  any  part  of  the  purchase  price  thereof  or  the
construction,  improvement or development cost thereof,  or any Debt incurred in
connection  therewith,  existing  prior to,  at the time of, or within  180 days
after,   the   acquisition   (including  any   acquisition   through  merger  or
consolidation)  or construction,  improvement or development  thereof,  provided
that any such Mortgage  shall only extend to the property,  equipment,  mines or
facilities,  or shares of stock or Debt,  acquired or  constructed,  improved or
developed,  or to property or mines, including undeveloped  mineralized deposits
or orebodies or segments thereof, on which the acquired or constructed, improved
or developed property, equipment, mines or facilities is situated; (e) Mortgages
securing certain tax-exempt obligations issued by governmental bodies, including
industrial  revenue  or  pollution  control  bonds;  (f)  Mortgages  created  in
connection with a project  financed,  or assets  acquired,  with, and created to
secure,  a Nonrecourse  Obligation;  (g) production  payments or other rights of
others to the output of mines, refineries, smelters, concentrators or production
facilities, including project financings, with respect to any property or assets
acquired,  constructed  or  improved  by the  Company or a  Subsidiary  with the
proceeds  of such  project  financings;  or  Mortgages  to secure the payment of
workmen's  compensation or the performance of tenders, bids or similar contracts
(including  surety or appeal bonds) and  Mortgages  entered into in the ordinary
course of business for similar purposes;  or (h) subject to certain limitations,
any extension, renewal or refunding of any Mortgage referred to in the foregoing
clauses  (a)  through  (g)  inclusive.  (Section  1006  of  Senior  Subordinated
Indenture)  The Senior  Subordinated  Indenture does not restrict the Company or
any Subsidiary from incurring unsecured Debt.

     Limitation on Certain Debt

     The  Company  shall  not  incur  any Debt  which  by its  terms is both (i)
subordinated  in right of payment to any Senior Debt and (ii) senior in right of
payment to the Senior Subordinated Debt Securities.


Events of Default

     The following are Events of Default  under the  Indentures  with respect to
Debt  Securities of any series:  (a) failure to pay principal of or premium,  if
any,  on any Debt  Security  of that  series  when due;  (b)  failure to pay any
interest on any Debt  Security of that series when due,  continued  for 30 days;
(c) failure to make any sinking fund  payment,  when due, in respect of any Debt
Security  of that  series;  (d) failure to perform in any  material  respect any
other covenant of the Company in the applicable Indenture (other than a covenant
included in such Indenture solely for the benefit of a series of Debt Securities
other than that series),  continued for 60 days after written notice as provided
in the respective  Indentures;  (e)  acceleration of any  indebtedness for money
borrowed by the Company in excess of $20 million,  if such  acceleration  is not
annulled  as  provided  in the  respective  Indentures;  (f)  certain  events of
bankruptcy,  insolvency  or  reorganization;  and (g) any other Event of Default
provided with respect to Debt Securities of that series. (Section 501)

     If an Event of Default with respect to outstanding  Debt  Securities of any
series  shall occur and be  continuing,  either the Trustee or the holders of at
least 25% in principal  amount of the outstanding Debt Securities of that series
by notice as provided in the  respective  Indentures  may declare the  principal
amount (or, if the Debt  Securities of that series are Original  Issue  Discount
Securities,  such  portion of the  principal  amount as may be  specified in the
terms  of that  series)  of all Debt  Securities  of that  series  to be due and
payable  immediately.  However,  at any time after a declaration of acceleration
with  respect to Debt  Securities  of any  series  has been  made,  but before a
judgment or decree based on such acceleration has been obtained,  the holders of
a majority in principal amount of the outstanding Debt Securities of that series
may, under certain circumstances,  rescind and annul such acceleration. (Section
502) For  information as to waiver of defaults,  see  "Modification  and Waiver"
below.

     The Indentures provide that, subject to the duty of the respective Trustees
thereunder during an Event of Default to act with the required standard of care,
such Trustee will be under no obligation to exercise any of its rights or powers
under the  respective  Indentures  at the  request  or  direction  of any of the
holders,  unless such  holders  shall have  offered to such  Trustee  reasonable
security or  indemnity.  (Sections  601 and 603) Subject to certain  provisions,
including  those  requiring  security or  indemnification  of the Trustees,  the
holders of a majority in principal  amount of the outstanding Debt Securities of
any  series  will  have the  right to  direct  the  time,  method  and  place of
conducting any proceeding for any remedy available to the applicable Trustee, or
exercising  any trust or power  conferred on such  Trustee,  with respect to the
Debt Securities of that series. (Section 512)

     No holder of a Debt Security of any series will have any right to institute
any  proceeding  with  respect  to the  applicable  Indenture  or for any remedy
thereunder,  unless such holder shall have  previously  given to the  applicable
Trustee written notice of a continuing  Event of Default (as defined) and unless
also  the  holders  of at  least  25%  in  aggregate  principal  amount  of  the
outstanding  Debt Securities of the same series shall have made written request,
and offered reasonable indemnity, to the Trustee to institute such proceeding as
trustee,  and the Trustee shall not have received from the holders of a majority
in aggregate  principal  amount of the  outstanding  Debt Securities of the same
series a  direction  inconsistent  with such  request  and shall have  failed to
institute  such  proceeding  within  60  days.   (Section  507)  However,   such
limitations do not apply to a suit instituted by a holder of a Debt Security for
enforcement of payment of the principal of and interest on such Debt Security on
or after the respective due dates expressed in such Debt Security. (Section 508)

     The Company  will be  required to  furnish to  the Trustees  annually a
statement as to the performance by the Company of its  obligations under the
respective Indentures  and as to any default  in such performance.  (Section
1004)

Modification and Waiver

     Without  the  consent of any holder of  outstanding  Debt  Securities,  the
Company and the  Trustee  may amend or  supplement  the  Indentures  or the Debt
Securities to cure any ambiguity, defect or inconsistency, or to make any change
that does not  materially  adversely  affect  the  rights of any  holder of Debt
Securities.  (Section 901) Other  modifications and amendments of the respective
Indentures  may be made by the Company  and the Trustee  with the consent of the
holders  of not less  than a  majority  in  aggregate  principal  amount  of the
outstanding Debt Securities of each series affected thereby; provided,  however,
that no such modification or amendment may, without the consent of the holder of
each outstanding Debt Security affected thereby:  (a) change the Stated Maturity
of the  principal  of, or any  installment  of principal of, or interest on, any
Debt Security;  (b) reduce the principal  amount of, the rate of interest on, or
the premium,  if any,  payable upon the redemption  of, any Debt  Security;  (c)
reduce the amount of principal of an Original  Issue Discount  Security  payable
upon acceleration of the Maturity  thereof;  (d) change the place or currency of
payment of principal of, or premium,  if any, or interest on any Debt  Security;
(e) impair the right to institute suit for the  enforcement of any payment on or
with respect to any Debt Security on or after the Stated  Maturity or Redemption
Date thereof;  (f) modify the  conversion  provisions  applicable to Convertible
Debt  Securities  in a manner  adverse to the  holders  thereof;  (g) modify the
subordination  provisions  applicable to Senior  Subordinated Debt Securities or
Subordinated Debt Securities in a manner adverse to the holders thereof;  or (h)
reduce the percentage in principal  amount of outstanding Debt Securities of any
series,  the  consent of the holders of which is required  for  modification  or
amendment of the applicable  Indenture or for waiver of compliance  with certain
provisions  of the  applicable  Indenture  or for  waiver of  certain  defaults.
(Section 902)

     The holders of at least a majority  in  aggregate  principal  amount of the
outstanding  Debt  Securities  of any series may on behalf of the holders of all
Debt  Securities  of that series  waive,  insofar as that  series is  concerned,
compliance by the Company with certain  covenants of the  applicable  Indenture.
(Section  1009) The holders of not less than a majority in  principal  amount of
the  outstanding  Debt Securities of any series may, on behalf of the holders of
all Debt Securities of that series,  waive any past default under the applicable
Indenture  with respect to that  series,  except a default in the payment of the
principal  of, or premium,  if any, or  interest  on, any Debt  Security of that
series or in respect of a provision which under the applicable  Indenture cannot
be  modified or amended  without  the consent of the holder of each  outstanding
Debt Security of that series affected. (Section 513)

Consolidation, Merger and Sale of Assets

     The Company may not consolidate or merge with or into, or transfer or lease
all or substantially all of its assets to, any Person,  and any other Person may
not consolidate or merge with or into, the Company, unless (i) the Person formed
by such  consolidation  or into which the Company is merged or which acquires or
leases all or substantially  all of the assets of the Company  expressly assumes
all of the Company's obligations on the Debt Securities and under the Indenture,
(ii)  immediately  after giving effect to such  transaction  no Event of Default
shall have happened and be  continuing,  and (iii) certain other  conditions are
met. (Article Eight)

Defeasance

     If so indicated in the applicable Prospectus Supplement with respect to the
Debt Securities of a series,  the Company,  at its option (i) will be discharged
from any and all  obligations  in respect of the Debt  Securities of such series
(except for certain  obligations  to register  the  transfer or exchange of Debt
Securities of such series, to replace destroyed,  stolen, lost or mutilated Debt
Securities of such series, and to maintain an office or agency in respect of the
Debt  Securities  and hold moneys for payment in trust) or (ii) will be released
from its  obligations  to comply with the  covenants  that are  specified  under
"Covenants with Respect to Senior Debt Securities" or "Covenants with Respect to
Senior  Subordinated Debt Securities" above (and any covenants that may apply to
Subordinated  Debt  Securities)  with  respect  to the Debt  Securities  of such
series,  and the occurrence of an event described in clause (d) under "Events of
Default"  above with respect to any defeased  covenant,  and clauses (e) and (g)
under  "Events of Default"  above  shall no longer be Events of  Default,  if in
either case the Company  irrevocably  deposits with the Trustee, in trust, money
or U.S. Government  Obligations that through the payment of interest thereon and
principal thereof in accordance with their terms will provide money in an amount
sufficient to pay all the principal of and premium,  if any, and any interest on
the Debt Securities of such series on the dates such payments are due (which may
include one or more  redemption  dates  designated by the Company) in accordance
with the terms of such Debt Securities. Such a trust may only be established if,
among  other  things,  (a) no Event of Default or event which with the giving of
notice or lapse of time,  or both,  would  become an Event of Default  under the
applicable  Indenture  shall have occurred and be continuing on the date of such
deposit,  (b) no Event of Default  described  under clause (f) under  "Events of
Default"  above or event  which with the  giving of notice or lapse of time,  or
both,  would  become an Event of Default  described  under such clause (f) shall
have occurred and be continuing at any time during the period ending on the 91st
day following such date of deposit,  and (c) the Company shall have delivered an
Opinion of Counsel to the effect  that the holders of the Debt  Securities  will
not recognize  gain or loss for United States  Federal  income tax purposes as a
result of such  deposit  or  defeasance  and will be  subject  to United  States
Federal income tax in the same manner as if such defeasance had not occurred. In
the event the Company fails to comply with its remaining  obligations  under the
applicable  Indenture  after a defeasance of such  Indenture with respect to the
Debt  Securities of any series as described under clause (ii) above and the Debt
Securities of such series are declared due and payable because of the occurrence
of any  undefeased  Event of  Default,  the amount of money and U.S.  Government
Obligations on deposit with the Trustee may be  insufficient  to pay amounts due
on the Debt Securities of such series at the time of the acceleration  resulting
from such Event of Default.  However,  the Company will remain liable in respect
to such payments. (Article Thirteen)

     Notwithstanding  the description set forth under  "Subordination  of Senior
Subordinated  Debt Securities and Subordinated  Debt  Securities"  above, in the
event  that  the  Company  deposits  money  or U.S.  Government  Obligations  in
compliance  with  the  Indenture  that  governs  the  Senior  Subordinated  Debt
Securities  or  Subordinated  Debt  Securities,  as the case may be, in order to
defease all or certain of its obligations with respect to the applicable  series
of Debt Securities,  the moneys or U.S. Government Obligations so deposited will
not be subject to the subordination  provisions of the applicable  Indenture and
the  indebtedness  evidenced  by such  series  of Debt  Securities  will  not be
subordinated   in  right  of  payment  to  the  holders  of  applicable   Senior
Indebtedness to the extent of the moneys or U.S.
Government Obligations so deposited.

Provision of Financial Information

     The Company will provide to the Trustee a copy of all financial  reports it
files with the Commission.  If, during any reporting period,  the Company is not
required to file such reports with the Commission,  the Company will provide the
Trustee substantially similar financial reports concerning the Company as if the
Company were so required.

Governing Law

     The Indentures and the Debt  Securities  will be governed by, and construed
in accordance with, the laws of the State of New York. (Section 112)

Regarding the Trustee

     Chemical Trust Company of California,  an affiliate of Chemical Bank, N.A.,
will serve as Trustee under the Indenture  governing the Senior Debt Securities.
Chemical Bank, N.A. is a lender and the administrative agent under the Company's
Revolving Credit Agreement.

     State Street Bank and Trust Company will be the Trustee under the Indenture
governing the Senior Subordinated Debt Securities.  It is also the trustee under
the indentures  governing the Company's 12% Senior  Subordinated Notes due 2001,
its  11-1/2%  Senior   Subordinated   Notes  due  2002,  and  its  8.70%  Senior
Subordinated Notes due May 15, 2005.

     The Trustee  with  respect to the  Indenture  governing  Subordinated  Debt
Securities will be specified in the applicable  Prospectus  Supplement  relating
thereto.

      If any Trustee  were to have any  conflicting  interest at the time of any
default under the Debt  Securities,  it would have to eliminate such conflict or
resign as Trustee. (Section 608)

determination  is being made exceeds 3% of Consolidated  Assets,  other than any
such portion  thereof which is pollution  control or other equipment or facility
financed by obligations  issued by a State or local government  unit;  provided,
however,  that Principal  Property  shall not include any smelters,  refineries,
mines,  concentrators  or facilities or any portions  thereof which the Board of

to the total  business  conducted  by the  Company  and its  Subsidiaries  as an

                         DESCRIPTION OF PREFERRED STOCK

     The following is a description  of certain  general terms and provisions of
the Preferred  Stock. The particular terms of any series of Preferred Stock will
be  described  in the  applicable  Prospectus  Supplement.  If so indicated in a
Prospectus  Supplement,  the terms of any such  series may differ from the terms
set forth below.  Certain  provisions  applicable to the Preferred Stock are set
forth below under "Description of Common Stock."

     The summary of terms of the  Company's  Preferred  Stock  contained in this
Prospectus  does not purport to be complete and is subject to, and  qualified in
its entirety by, the provisions of the Company's  Certificate  of  Incorporation
and the  certificate  of  designations  relating to each series of the Preferred
Stock (the  "Certificate of  Designations"),  the form of which is an exhibit to
the Registration Statement of which this Prospectus is a part.

     The  Company's  Certificate  of  Incorporation  authorizes  the issuance of
50,000,000  shares of preferred  stock. In December 1993, the Company closed the
sale of 2.0 million shares of 6% Cumulative  Convertible Preferred Stock, Series
E, $.01 par value. See "Series E Preferred Stock" below.  Additionally,  in July
1993,  the Company issued 2.0 million  shares of 5 5/8%  Cumulative  Convertible
Preferred Stock, Series D, $.01 par value. See "Series D Preferred Stock" below.
The Company also has 5,112,765  shares of Series C Convertible  Preferred Stock,
$.01 par value,  reserved for issuance in certain  instances.  See "Reserved but
Unissued Series C Convertible  Preferred Stock" below.  The Company's  preferred
stock may be issued from time to time in one or more series, without stockholder
approval.  Subject to  limitations  prescribed by law, the Board of Directors is
authorized to determine the voting powers (if any), designation, preferences and
relative,  participating,  optional or other special rights, and qualifications,
limitations or restrictions thereof, for each series of preferred stock that may
be issued, and to fix the number of shares of each such series.  Thus, the Board
of Directors,  without  stockholder  approval,  could  authorize the issuance of
preferred  stock with voting,  conversion and other rights that could  adversely
affect the  voting  power and other  rights of holders of Common  Stock or other
series of preferred  stock or that could have the effect of delaying,  deferring
or  preventing a change in control of the Company.  See  "Description  of Common
Stock" herein.

     The Preferred  Stock shall have the dividend,  liquidation,  redemption and
voting  rights  set  forth  below  unless  otherwise  provided  in a  Prospectus
Supplement  relating  to  a  particular  series  of  the  Preferred  Stock.  The
applicable Prospectus Supplement will describe the following terms of the series
of Preferred Stock in respect of which this Prospectus is being  delivered:  (1)
the  designation  and  stated  value per share of such  Preferred  Stock and the
number of shares  offered;  (2) the amount of liquidation  preference per share;
(3) the initial  public  offering  price at which such  Preferred  Stock will be
issued and any  exchange  upon which the stock will be listed;  (4) the dividend
rate (or method of  calculation),  the dates on which dividends shall be payable
and the dates from which dividends  shall commence to cumulate,  if any; (5) any
redemption or sinking fund  provisions;  (6) any conversion or exchange  rights;
(7) whether the Company  has  elected to offer  Depositary  Shares as  described
below under "Description of Depositary  Shares";  and (8) any additional voting,
dividend,  liquidation,  redemption, sinking fund and other rights, preferences,
privileges, limitations and restrictions.

General

     The Preferred  Stock  offered  hereby will be issued in one or more series.
The holders of Preferred Stock will have no preemptive rights.  Preferred Stock,
upon issuance against full payment of the purchase price therefor, will be fully
paid and nonassessable.  Neither the par value nor the liquidation preference is
indicative of the price at which the Preferred  Stock will actually  trade on or
after the date of issuance.

     As described under "Description of Depositary  Shares," the Company may, at
its option,  elect to offer Depositary Shares evidenced by Depositary  Receipts,
each  representing  a fractional  interest  (to be  specified in the  Prospectus
Supplement  relating to the particular series of the Preferred Stock) in a share
of the  particular  series of the Preferred  Stock issued and  deposited  with a
Depositary (as defined below).

Rank

     The Preferred  Stock shall,  with respect to dividend  rights and rights on
liquidation,  winding  up and  dissolution  of the  Company,  rank  prior to the
Company's Common Stock and to all other classes and series of equity  securities
of the Company now or hereafter  authorized,  issued or outstanding  (the Common
Stock and such other classes and series of equity securities collectively may be
referred to herein as the "Junior  Stock"),  other than any classes or series of
equity  securities of the Company  ranking on a parity with (the "Parity Stock")
or senior to (the "Senior  Stock") the Preferred Stock as to dividend rights and
rights upon liquidation, winding up or dissolution of the Company. The Preferred
Stock shall be junior to all  outstanding  debt of the  Company.  The  Preferred
Stock  shall be subject to  creation of Senior  Stock,  Parity  Stock and Junior
Stock to the extent not expressly  prohibited by the  Company's  Certificate  of
Incorporation.

Dividends

     Holders of shares of Preferred Stock shall be entitled to receive, when, as
and if declared by the Board of  Directors  out of funds of the Company  legally
available for payment,  cash dividends,  payable at such dates and at such rates
per share per annum as set forth in the applicable Prospectus  Supplement.  Such
rate may be fixed or variable or both.  Each declared  dividend shall be payable
to holders of record as they  appear at the close of business on the stock books
of the Company (or, if  applicable,  on the records of the  Depositary)  on such
record  dates,  not more than 60  calendar  days  preceding  the  payment  dates
therefor,  as are  determined by the Board of Directors  (each of such dates,  a
"Record Date").

     Such  dividends  may be  cumulative  or  noncumulative,  as provided in the
Prospectus  Supplement.  If  dividends  on  a  series  of  Preferred  Stock  are
noncumulative  and if the Board of  Directors  fails to  declare a  dividend  in
respect of a dividend  period with respect to such series,  then holders of such
Preferred  Stock  will have no right to  receive a  dividend  in respect of such
dividend period, and the Company will have no obligation to pay the dividend for
such  period,  whether  or not  dividends  are  declared  payable  on any future
dividend  payment  dates.  Dividends  on the shares of each series of  Preferred
Stock for which  dividends are cumulative will accrue from the date on which the
Company  initially  issues shares of such series.  Accumulations of dividends on
shares of Preferred Stock will not bear interest.

     No full  dividends  shall be  declared  or paid or set apart for payment on
preferred  stock of the Company of any series  ranking,  as to  dividends,  on a
parity with or junior to the series of Preferred Stock offered by the Prospectus
Supplement  attached  hereto  for  any  period  unless  full  dividends  for the
immediately  preceding  dividend period on such Preferred  Stock  (including any
accumulation  in respect of unpaid  dividends  for prior  dividend  periods,  if
dividends on such Preferred Stock are cumulative) have been or contemporaneously
are declared and paid or declared and a sum sufficient  for the payment  thereof
is set apart for such payment.  When dividends are not so paid in full (or a sum
sufficient for such full payment is not so set apart) upon such Preferred  Stock
and any other preferred stock of the Company ranking on a parity as to dividends
with the Preferred  Stock,  dividends  upon shares of such  Preferred  Stock and
dividends on such other  preferred  stock shall be declared pro rata so that the
amount of dividends  declared per share on such Preferred  Stock and such Parity
Stock  shall in all  cases  bear to each  other  the  same  ratio  that  accrued
dividends on the shares of such Preferred Stock and accrued  dividends on shares
of such  Parity  Stock,  bear to each other as of their  respective  immediately
preceding  dividend  periods.  Unless full  dividends on the series of Preferred
Stock offered by the Prospectus  Supplement  attached  hereto have been declared
and paid or set apart for payment for the immediately  preceding dividend period
(including any  accumulation  in respect of unpaid  dividends for prior dividend
periods,  if  dividends on such  Preferred  Stock are  cumulative),  (a) no cash
dividend or distribution (other than in shares of Junior Stock) may be declared,
set aside or paid on the Junior  Stock,  (b) the  Company  may not,  directly or
indirectly,  repurchase,  redeem or  otherwise  acquire any shares of its Junior
Stock (or pay any monies into a sinking fund for the  redemption  of any shares)
except by conversion into or exchange for Junior Stock or in connection with any
employee benefit plan or arrangement,  and (c) the Company may not,  directly or
indirectly, repurchase, redeem or otherwise acquire any shares of such Preferred
Stock or Parity Stock (or pay any monies into a sinking fund for the  redemption
of any shares of any such stock)  otherwise  than pursuant to pro rata offers to
purchase  or a  concurrent  redemption  of all,  or a pro rata  portion,  of the
outstanding  shares  of  such  Preferred  Stock  and  Parity  Stock  (except  by
conversion  into or exchange for Junior Stock or in connection with any employee
benefit plan or arrangement).

Convertibility

     The terms,  if any, on which shares of Preferred Stock of any series may be
exchanged  for or converted  (mandatorily  or  otherwise)  into shares of Common
Stock of the Company or another series of preferred stock or other securities of
the Company will be set forth in the Prospectus Supplement relating thereto. See
"Description of Common Stock."

Redemption

     The terms,  if any, on which shares of Preferred Stock of any series may be
redeemed will be set forth in the related Prospectus Supplement.

Liquidation

     Unless otherwise specified in the applicable Prospectus Supplement,  in the
event of a voluntary or  involuntary  liquidation,  dissolution or winding up of
the affairs of the Company,  the holders of a series of Preferred  Stock will be
entitled,  subject to the rights of creditors,  but before any  distribution  or
payment to the holders of Common Stock or any other  security  ranking junior to
the Preferred Stock on liquidation, dissolution or winding up of the Company, to
receive  out of the assets of the  Company,  whether  such assets are capital or
surplus and whether or not any  dividends  as such are  declared,  an amount per
share as set forth in the  related  Prospectus  Supplement  plus any accrued and
unpaid  dividends  for prior  dividend  periods,  if dividends on such series of
Preferred Stock are cumulative.  If the amounts  available for distribution with
respect to the Preferred  Stock and all other  outstanding  stock of the Company
ranking on a parity with the Preferred Stock upon liquidation are not sufficient
to satisfy the full  liquidation  rights of all the outstanding  Preferred Stock
and stock ranking on a parity therewith, then the holders of each series of such
stock will share ratably in any such distribution of assets in proportion to the
full  respective  preferential  amount (which in the case of preferred stock may
include accumulated dividends) to which they are entitled.  After payment of the
full amount of the  liquidation  preference,  the holders of shares of Preferred
Stock will not be entitled to any further  participation  in any distribution of
assets by the Company.

Voting

     The  Preferred  Stock of a series will not be  entitled to vote,  except as
provided  below or in the  applicable  Prospectus  Supplement and as required by
applicable law. Unless otherwise specified in the related Prospectus Supplement,
at any time dividends in an amount equal to six quarterly  dividend  payments on
the Preferred  Stock shall have accrued and be unpaid,  holders of the Preferred
Stock shall have the right to a separate  class vote  (together with the holders
of shares of any Parity Stock upon which like voting rights have been  conferred
and are exercisable,  "Voting Parity Stock") to elect two additional  members to
the Board of Directors at the next annual meeting of stockholders (or, if called
by 25% in interest of such Preferred  Stock, a special meeting of  stockholders)
and to maintain such director  representation  until  dividends on the Preferred
Stock have been paid in full  (including any  accumulation  in respect of unpaid
dividends from prior dividend periods,  if dividends on such Preferred Stock are
cumulative)  or declared  and a sum  sufficient  for the payment  thereof is set
apart  for such  payment.  Additionally,  without  the  affirmative  vote of the
holders of two-thirds of the shares of Preferred Stock then outstanding  (voting
separately as a class  together with any Voting Parity  Stock),  the Company may
not, either directly or indirectly or through merger or  consolidation  with any
other corporation,  (i) approve the authorization,  creation or issuance,  or an
increase in the  authorized  or issued  amount,  of any class or series of stock
ranking  prior to the shares of Preferred  Stock in rights and  preferences,  or
(ii) amend,  alter or repeal its Certificate of Incorporation or the Certificate
of  Designations  relating  to  the  Preferred  Stock  so as to  materially  and
adversely  change the voting  powers,  rights or  preferences  of the  Preferred
Stock, provided, however, that if any such amendment, alteration or repeal would
materially  adversely  affect any voting  powers,  rights or  preferences of the
Preferred Stock or another series of Voting Parity Stock that are not enjoyed by
some or all of the  other  series  otherwise  entitled  to  vote  in  accordance
herewith,  the affirmative  vote of at least two-thirds of the votes entitled to
be cast by the  holders of all series  similarly  affected  shall be required in
lieu of the affirmative  vote of at least two-thirds of the votes entitled to be
cast by the holders of the shares of Preferred Stock and the Voting Parity Stock
otherwise entitled to vote in accordance herewith;  and provided,  further, that
no vote of the holders of  Preferred  Stock shall be required if, at or prior to
the time when such  amendment,  alteration or repeal is to take effect,  or when
the issuance of any such class or series of stock ranking prior to the shares of
Preferred  Stock in rights and  preferences,  is to be made, as the case may be,
provision is made for the  redemption  of all shares of  Preferred  Stock at the
time  outstanding.  An amendment which increases the number of authorized shares
of or  authorizes  the  creation  or  issuance  of other  classes  or  series of
preferred  stock ranking junior to or on a parity with the Preferred  Stock with
respect to the payment of dividends or distribution of assets upon  liquidation,
dissolution  or winding up, or  substitutes  the  surviving  entity in a merger,
consolidation,  reorganization  or other business  combination  for the Company,
shall not be  considered to be an adverse  change  requiring the approval of the
Preferred Stock.

     As more fully described under  "Description of Depositary Shares" below, if
the Company elects to issue Depositary Shares, each representing a fraction of a
share of a series of the Preferred  Stock,  each such Depositary  Share will, in
effect, be entitled to such fraction of a vote per Depositary Share.

No Other Rights

     The shares of a series of  Preferred  Stock will not have any  preferences,
voting  powers or  relative,  participating,  optional or other  special  rights
except as set forth above or in the related  Prospectus  Supplement,  and in the
Certificate  of  Incorporation  and  the  Certificate  of  Designations  related
thereto, or as otherwise required by law.

Transfer Agent and Registrar

     The transfer agent for each series of Preferred  Stock will be described in
the related Prospectus Supplement.

Series E Preferred Stock

     In December  1993,  the Company  issued 2.0 million shares of 6% Cumulative
Convertible  Preferred Stock,  Series E, $.01 par value (the "Series E Preferred
Stock").  Holders of the Series E Preferred Stock are entitled to receive, when,
as, and if declared by the  Company's  Board of Directors  out of funds  legally
available  therefore,  cumulative cash dividends at the rate of 6% per annum (an
amount  equivalent to $3.00 per annum per share),  payable quarterly in arrears.
In the event of any voluntary or involuntary liquidation, dissolution or winding
up of the Company,  the holders of the Series E Preferred Stock will be entitled
to receive distributions in the amount of $50.00 per share, plus all accrued and
unpaid  dividends.  Each share of Series E Preferred  Stock is  convertible,  in
whole or in part, at any time, unless previously redeemed, into 3.5945 shares of
Common Stock  (equivalent  to a  conversion  price of $13.91 per share of Common
Stock).  The  conversion  rate is subject to adjustment  upon the  occurrence of
certain events.

     The Series E Preferred  Stock ranks junior to all  outstanding  debt of the
Company.  With respect to the payment of dividends and amounts upon liquidation,
dissolution  or winding up, the Series E Preferred  Stock ranks on a parity with
the  Company's  Series D Preferred  Stock and senior to the Common Stock and the
Series C Preferred Stock.

     Whenever  dividends on the Series E Preferred  Stock are in arrears for six
quarterly  dividend  periods,  holders of the Series E Preferred  Stock  (voting
separately as a class together with holders of shares of the Company's  Series D
Preferred Stock and any other class or series of equity securities  ranking on a
parity  with the  Series E  Preferred  Stock)  will  have the right to elect two
additional  directors to serve on the  Company's  Board of Directors  until such
dividend  arrearage is eliminated.  In addition,  certain  changes that would be
materially  adverse to the rights of holders of the Series E Preferred Stock and
voting parity stock cannot be made without the affirmative vote of two-thirds of
the shares of Series E  Preferred  Stock and voting  parity  stock,  voting as a
single class, entitled to be cast thereon.

     The Series E Preferred  Stock is not redeemable  prior to December 1, 1996.
On and after such date, the Series E Preferred Stock is redeemable at the option
of the  Company,  in  whole or in part,  initially  for  $52.10  per  share  and
thereafter at prices declining ratably annually on each December 1 to $50.00 per
share on and after December 1, 2003.

Series D Preferred Stock

     In July 1993, the Company  issued 2.0 million  shares of 5-5/8%  Cumulative
Convertible  Preferred Stock,  Series D, $.01 par value (the "Series D Preferred
Stock").  Holders of the Series D Preferred Stock are entitled to receive, when,
as, and if declared by the  Company's  Board of Directors  out of funds  legally
available  therefore,  cumulative cash dividends at the rate of 5-5/8% per annum
(an amount  equivalent  to $2.8125 per annum per share),  payable  quarterly  in
arrears. In the event of any voluntary or involuntary  liquidation,  dissolution
or winding up of the Company,  the holders of the Series D Preferred  Stock will
be entitled to receive distributions in the amount of $50.00 per share, plus all
accrued  and  unpaid  dividends.  Each  share  of  Series D  Preferred  Stock is
convertible,  in whole or in part, at any time, unless previously redeemed, into
3.448 shares of Common  Stock  (equivalent  to a conversion  price of $14.50 per
share of Common Stock).  The conversion  rate is subject to adjustment  upon the
occurrence of certain events.

     The Series D Preferred  Stock ranks junior to all  outstanding  debt of the
Company.  With respect to the payment of dividends and amounts upon liquidation,
dissolution  or winding up, the Series D Preferred  Stock ranks on a parity with
the  Company's  Series E Preferred  Stock and senior to the Common Stock and the
Series C Preferred Stock.

     Whenever  dividends on the Series D Preferred  Stock are in arrears for six
quarterly  dividend  periods,  holders of the Series D Preferred  Stock  (voting
separately as a class together with holders of shares of the Company's  Series E
Preferred Stock and any other class or series of equity securities  ranking on a
parity  with the  Series D  Preferred  Stock)  will  have the right to elect two
additional  directors to serve on the  Company's  Board of Directors  until such
dividend  arrearage is eliminated.  In addition,  certain  changes that would be
materially  adverse to the rights of holders of the Series D Preferred Stock and
voting parity stock cannot be made without the affirmative vote of two-thirds of
the shares of Series D  Preferred  Stock and voting  parity  stock,  voting as a
single class, entitled to be cast thereon.

     The Series D Preferred  Stock is not redeemable  prior to July 20, 1996. On
and after such date, the Series D Preferred Stock is redeemable at the option of
the Company, in whole or in part, initially for $51.969 per share and thereafter
at prices declining  ratably annually on each July 20 to $50.00 per share on and
after July 20, 2003.

Reserved but Unissued Series C Convertible Preferred Stock

     The Company has reserved 5,112,765 shares of Series C Convertible Preferred
Stock, $.01 par value per share (the "Series C Preferred  Stock"),  for issuance
upon exercise of outstanding  warrants if, for any reason, it is unable to issue
Common Stock to satisfy applicable exercise requirements.  No Series C Preferred
Stock is outstanding  and the Company is not presently  aware of any reason that
would require it to issue such stock or preclude it from issuing Common Stock.

     The  Series C  Preferred  Stock  ranks,  with  respect  to the  payment  of
dividends  and the  distribution  of assets,  junior to all series of  Preferred
Stock. Subject to the rights of a superior series of preferred stock, each share
of Series C Preferred Stock is entitled to receive, when, as, and if declared by
the  Board  of  Directors  out of funds  legally  available  for  that  purpose,
dividends  payable in cash in an amount  per share  equal to the  aggregate  per
share amount of all cash  dividends,  and the  aggregate per share amount of all
non-cash  dividends  or other  distributions,  other than a dividend  payable in
shares of Common Stock, declared on the Common Stock.

     Each share of Series C Preferred  Stock is entitled to such number of votes
as each share of Common  Stock and,  except as otherwise  required by law,  will
vote together  with the Common Stock as a single  class.  Each share of Series C
Preferred  Stock is  convertible  at any time into one  share of fully  paid and
non-assessable Common Stock.

     If the Company  declares any dividend on the Common Stock payable in shares
of Common Stock, or effects a subdivision or combination or consolidation of the
outstanding  shares of Common Stock into a greater or lesser number of shares of
Common  Stock,  then the  dividends  and the  number of votes per share to which
holders of shares of Series C Preferred  Stock are  entitled to will be adjusted
by multiplying the amount or number the holders were previously entitled to by a
fraction,  the  numerator  of which is the  number of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     The holders of Series C Preferred  Stock have no preemptive  rights and are
not subject to redemption. In the event of liquidation,  dissolution, or winding
up of the  Company,  prior to  distribution  to the  holders  of shares of stock
ranking  junior  to the  Series C  Preferred  Stock,  the  holders  of  Series C
Preferred  Stock  are  entitled  to $.10 per share  plus an amount  equal to any
unpaid dividends and  distributions  on the Series C Preferred  Stock,  provided
that the  holders of Series C  Preferred  Stock  shall be entitled to receive an
aggregate  amount  per  share,  subject  to  certain  adjustments,  equal to the
aggregate  amount to be  distributed  per share to  holders  of shares of Common
Stock.

                        DESCRIPTION OF DEPOSITARY SHARES

     The description set forth below and in any Prospectus Supplement of certain
provisions  of the Deposit  Agreement (as defined  below) and of the  Depositary
Shares and Depositary Receipts does not purport to be complete and is subject to
and qualified in its entirety by reference to the forms of Deposit Agreement and
Depositary  Receipts  relating to each series of the Preferred  Stock which have
been or will be  filed  with  the  Commission  at or  prior  to the  time of the
offering of such series of the Preferred Stock.

General

     The Company  may, at its option,  elect to offer  fractional  interests  in
shares of Preferred  Stock,  rather than shares of Preferred Stock. In the event
such  option is  exercised,  the  Company  will  provide  for the  issuance by a
Depositary to the public of receipts for Depositary  Shares,  each of which will
represent a fractional  interest (to be set forth in the  Prospectus  Supplement
relating to a particular  series of the Preferred Stock which will be filed with
the  Commission  at or prior to the time of the  offering  of such series of the
Preferred Stock as described below).

     The shares of any series of the Preferred  Stock  underlying the Depositary
Shares  will be  deposited  under a separate  Deposit  Agreement  (the  "Deposit
Agreement")  between  the Company  and a bank or trust  company  selected by the
Company  having its principal  office in the United States and having a combined
capital and surplus of at least $50,000,000 (the  "Depositary").  The Prospectus
Supplement relating to a series of Depositary Shares will set forth the name and
address of the Depositary.  Subject to the terms of the Deposit Agreement,  each
owner of a Depositary  Share will be entitled,  in proportion to the  applicable
fractional  interest in a share of Preferred  Stock  underlying  such Depositary
Shares, to all the rights and preferences of the Preferred Stock underlying such
Depositary  Share  (including  dividend,  voting,  redemption,   conversion  and
liquidation rights).

     The  Depositary  Shares will be evidenced  by  Depositary  Receipts  issued
pursuant to the Deposit Agreement.

     Pending the preparation of definitive  engraved  Depositary  Receipts,  the
Depositary  may,  upon  the  written  order  of  the  Company,  issue  temporary
Depositary  Receipts  substantially  identical  to (and  entitling  the  holders
thereof to all the rights pertaining to) the definitive  Depositary Receipts but
not  in  definitive  form.  Definitive  Depositary  Receipts  will  be  prepared
thereafter without unreasonable delay, and temporary Depositary Receipts will be
exchangeable for definitive Depositary Receipts at the Company's expense.

     Upon  surrender of Depositary  Receipts at the office of the Depositary and
upon payment of the charges provided in the Deposit Agreement and subject to the
terms thereof,  a holder of Depositary Shares is entitled to have the Depositary
deliver to such  holder  the whole  shares of  Preferred  Stock  underlying  the
Depositary Shares evidenced by the surrendered Depositary Receipts.

Dividends and Other Distributions

     The   Depositary   will   distribute  all  cash  dividends  or  other  cash
distributions  received in respect of the Preferred  Stock to the record holders
of  Depositary  Shares  relating to such  Preferred  Stock in  proportion to the
numbers of such  Depositary  Shares owned by such holders on the relevant record
date. The  Depositary  shall  distribute  only such amount,  however,  as can be
distributed without attributing to any holder of Depositary Shares a fraction of
one cent,  and any balance not so  distributed  shall be added to and treated as
part of the next sum  received  by the  Depositary  for  distribution  to record
holders of Depositary Shares.

     In the event of a  distribution  other than in cash,  the  Depositary  will
distribute  property  received by it to the record holders of Depositary  Shares
entitled  thereto,  unless the Depositary  determines that it is not feasible to
make such  distribution,  in which case the Depositary may, with the approval of
the Company,  sell such property and  distribute the net proceeds from such sale
to such holders.

     The Deposit Agreement will also contain  provisions  relating to the manner
in which any subscription or similar rights offered by the Company to holders of
the Preferred Stock shall be made available to holders of Depositary Shares.

Redemption of Depositary Shares

     If a series of the Preferred  Stock  underlying  the  Depositary  Shares is
subject to redemption,  the Depositary Shares will be redeemed from the proceeds
received by the Depositary  resulting from the redemption,  in whole or in part,
of such series of the Preferred  Stock held by the  Depositary.  The  Depositary
shall mail notice of redemption not less than 30 and not more than 60 days prior
to the date fixed for redemption to the record holders of the Depositary  Shares
to be so redeemed at their  respective  addresses  appearing in the Depositary's
books. The redemption price per Depositary Share will be equal to the applicable
fraction of the  redemption  price per share payable with respect to such series
of the Preferred  Stock.  Whenever the Company redeems shares of Preferred Stock
held by the  Depositary,  the Depositary  will redeem as of the same  redemption
date the number of Depositary  Shares  relating to shares of Preferred  Stock so
redeemed.  If less than all of the  Depositary  Shares are to be  redeemed,  the
Depositary  Shares to be redeemed  will be selected by lot or pro rata as may be
determined by the Depositary.

     After the date fixed for  redemption,  the Depositary  Shares so called for
redemption  will no longer be deemed  to be  outstanding  and all  rights of the
holders of the  Depositary  Shares will  cease,  except the right to receive the
moneys payable upon such redemption and any money or other property to which the
holders of such  Depositary  Shares  were  entitled  upon such  redemption  upon
surrender  to  the  Depositary  of  the  Depositary   Receipts  evidencing  such
Depositary Shares.

Voting the Preferred Stock

     Upon receipt of notice of any meeting at which the holders of the Preferred
Stock are entitled to vote, the Depositary will mail the  information  contained
in such  notice of  meeting  to the  record  holders  of the  Depositary  Shares
relating to such Preferred Stock.  Each record holder of such Depositary  Shares
on the  record  date  (which  will be the same date as the  record  date for the
Preferred  Stock) will be entitled to instruct the Depositary as to the exercise
of the  voting  rights  pertaining  to the number of shares of  Preferred  Stock
underlying  such holder's  Depositary  Shares.  The  Depositary  will  endeavor,
insofar  as  practicable,  to vote the  number  of  shares  of  Preferred  Stock
underlying such Depositary Shares in accordance with such instructions,  and the
Company  will  agree to take all  action  which may be deemed  necessary  by the
Depositary  in order to  enable  the  Depositary  to do so.  To the  extent  the
Depositary does not receive specific instructions from the holders of Depositary
Shares relating to such Preferred  Stock, it will vote shares of Preferred Stock
in accordance with the recommendation of the Company, unless otherwise indicated
in the Prospectus Supplement.

Amendment and Termination of Depositary Agreement

     The form of Depositary  Receipt  evidencing the  Depositary  Shares and any
provision  of the  Deposit  Agreement  may at any time be amended  by  agreement
between the Company and the Depositary.  However, any amendment which materially
and adversely  alters the rights of the existing  holders of  Depositary  Shares
will not be  effective  unless such  amendment  has been  approved by the record
holders of at least a majority  of the  Depositary  Shares then  outstanding.  A
Deposit Agreement may be terminated by the Company or the Depositary only if (i)
all outstanding  Depositary  Shares relating  thereto have been redeemed or (ii)
there has been a final  distribution  in respect of the  Preferred  Stock of the
relevant series in connection with any liquidation, dissolution or winding up of
the Company and such  distribution  has been  distributed  to the holders of the
related Depositary Shares.

Charges of Depositary

     The Company will pay all transfer and other taxes and governmental  charges
arising  solely from the existence of the depositary  arrangements.  The Company
will pay charges of the Depositary in connection with the initial deposit of the
Preferred Stock and any redemption of the Preferred Stock. Holders of Depositary
Shares will pay other transfer and other taxes and governmental charges and such
other charges as are expressly provided in the Deposit Agreement to be for their
accounts.

Miscellaneous

     The Depositary will forward to the holders of Depositary Shares all reports
and  communications  from the Company which are delivered to the  Depositary and
which the Company is required to furnish to the holders of the Preferred Stock.

     Neither the Depositary nor the Company will be liable if it is prevented or
delayed  by law  or any  circumstance  beyond  its  control  in  performing  its
obligations under the Deposit Agreement.  The obligations of the Company and the
Depositary  under the Deposit  Agreement  will be limited to performance in good
faith of their duties  thereunder and they will not be obligated to prosecute or
defend any legal  proceeding  in respect of any  Depositary  Shares or Preferred
Stock unless  satisfactory  indemnity is  furnished.  They may rely upon written
advice of counsel or accountants,  or information provided by persons presenting
Preferred  Stock for  deposit,  holders of  Depositary  Shares or other  persons
believed to be competent and on documents believed to be genuine.

Resignation and Removal of Depositary

     The  Depositary  may resign at any time by delivering to the Company notice
of its election to do so, and the Company may at any time remove the Depositary,
any such  resignation  or  removal  to take  effect  upon the  appointment  of a
successor  Depositary  and its  acceptance of such  appointment.  Such successor
Depositary  must be  appointed  within 60 days after  delivery  of the notice of
resignation  or removal and must be a bank or trust company having its principal
office in the United  States and having a  combined  capital  and  surplus of at
least $50,000,000.

                          DESCRIPTION OF COMMON STOCK

     The  Company's  Certificate  of  Incorporation  authorizes  the issuance of
100,000,000 shares of common stock, $.01 par value per share ("Common Stock").

     The holders of Common Stock are entitled to receive  dividends  when and as
declared by the Board of Directors of the Company out of funds legally available
therefor,  provided  that if any  shares  of  preferred  stock  are at the  time
outstanding,  the payment of dividends  on Common  Stock or other  distributions
(including  purchases  of Common  Stock) may be subject to the  declaration  and
payment of full  cumulative  dividends,  and the  absence of  arrearages  in any
mandatory sinking fund, on outstanding shares of preferred stock.

     The holders of Common  Stock are entitled to one vote for each share on all
matters voted on by stockholders,  including elections of directors. The holders
of Common Stock do not have any conversion,  redemption or preemptive rights. In
the event of the dissolution,  liquidation or winding up of the Company, holders
of Common Stock are entitled to share ratably in any assets  remaining after the
satisfaction in full of the prior rights of creditors,  including holders of the
Company's  indebtedness,   and  the  aggregate  liquidation  preference  of  any
preferred stock then outstanding.

     All outstanding  shares of Common Stock are, and the shares offered hereby,
upon issuance, will be, fully paid and non-assessable.

     Certain provisions of the Company's Certificate of Incorporation and Bylaws
may be considered as having an anti-takeover effect. Such provisions empower the
Board of Directors to fix the rights and  preferences  of and to issue shares of
preferred  stock;  limit certain  substantial  stockholders  of the Company from
significantly  increasing  their  interest in the stock or assets of the Company
without  the consent of the Board of  Directors  and/or a  supermajority  of the
stockholders of the Company; prohibit stockholders of the Company from calling a
special meeting;  place  restrictions on the ability of stockholders to nominate
persons for the position of director; and require that the Board of Directors be
divided into three classes. In addition,  certain provisions of law may have the
effect  of  protecting  the  Company  against   undesired   takeover   attempts.
Specifically,  under  Delaware  law (and a similar  provision  of the  Company's
Certificate of  Incorporation),  in certain instances,  significant  holders (as
specified)  of the  Company's  voting  stock  may  not,  without  approval  of a
specified vote of the other stockholders,  or approval of the Company's Board of
Directors (or the independent  members  thereof) prior to becoming a significant
holder, acquire additional interests in the Company's assets or capital stock.

     The transfer agent for the Common Stock is Mellon Financial Services, whose
address is 111 Founders Plaza, 11th Floor, East Hartford, Connecticut 06108.

                            DESCRIPTION OF WARRANTS

General

     The  Company  may issue  Warrants,  including  Warrants  to  purchase  Debt
Securities ("Debt Warrants"),  as well as other types of Warrants.  Warrants may
be issued  independently  of or together  with any other  Securities  and may be
attached to or separate  from such  Securities.  Each series of Warrants will be
issued under a separate  warrant  agreement  (each a "Warrant  Agreement") to be
entered  into between the Company and a warrant  agent  ("Warrant  Agent").  The
Warrant Agent will act solely as an agent of the Company in connection  with the
Warrants of such series and will not assume any  obligation or  relationship  of
agency or trust for or with any holders or  beneficial  owners of Warrants.  The
following  sets forth  certain  general  terms and  provisions  of the  Warrants
offered  hereby.  Further  terms  of the  Warrants  and the  applicable  Warrant
Agreement are set forth in the applicable Prospectus Supplement.

issued with each such Debt Security;  (7) the currency or currencies,  including
composite  currencies,  in which the  principal of or any premium or interest on
the Debt  Securities  purchasable  upon  exercise of such Debt  Warrant  will be
payable;  (8) if applicable,  the date on and after which such Debt Warrants and

one time; (12) information with respect to book-entry  procedures,  if any; (13)

securities  (which may include  Preferred  Stock or Common Stock) for which such
Warrants are exercisable; (3) the price or prices at which such Warrants will be

transferable;  (7) if applicable,  a discussion of certain United States Federal
income tax considerations;  and (8) any other terms of such Warrants,  including
terms,  procedures and limitations relating to the exchange and exercise of such
Warrants.

                              PLAN OF DISTRIBUTION

     The Company may sell the Securities  (and, in the case of Preferred  Stock,
Depositary  Shares  representing  fractional  interests  therein) to one or more
underwriters for public offering and sale by them or may sell the Securities (or
Depositary Shares) to investors directly or through agents. Any such underwriter
or agent involved in the offer and sale of the Securities (or Depositary Shares)
will be named in the applicable Prospectus Supplement.  The Company has reserved
the right to sell the Securities (or Depositary Shares) directly to investors on
its own behalf in those jurisdictions where it is authorized to do so.

   
     Underwriters may offer and sell the Securities (or Depositary  Shares) at a
fixed price or prices that may be changed,  at market  prices  prevailing at the
time  of  sale,  at  prices  related  to such  prevailing  market  prices  or at
negotiated prices.  The Company also may, from time to time,  authorize dealers,
acting as the Company's  agents, to offer and sell the Securities (or Depositary
Shares) upon such terms and conditions as set forth in the applicable Prospectus
Supplement.  In  connection  with  the  sale of the  Securities  (or  Depositary
Shares),  underwriters may receive  compensation from the Company in the form of
underwriting  discounts or  commissions  and may also receive  commissions  from
purchasers of the  Securities  (or  Depositary  Shares) for whom they may act as
agent. Underwriters may sell the Securities (or Depositary Shares) to or through
dealers,  and such dealers may receive  compensation  in the form of  discounts,
concessions or commissions  from the  underwriters  and/or  commissions from the
purchasers for whom they may act as agents.     

     Any underwriting compensation paid by the Company to underwriters or agents
in connection  with the offering of the Securities (or Depositary  Shares),  and
any  discounts,   concessions  or  commissions   allowed  by   underwriters   to
participating   dealers,   will  be  set  forth  in  the  applicable  Prospectus
Supplement.  Dealers  and  agents  participating  in  the  distribution  of  the
Securities  (or  Depositary  Shares) may be deemed to be  underwriters,  and any
discounts and  commissions  received by them and any profit  realized by them on
resale of the Securities (or Depositary Shares) may be deemed to be underwriting
discounts  and  commissions.  Underwriters,  dealers and agents may be entitled,
under agreements entered into with the Company,  to indemnification  against and
contribution toward certain civil liabilities.

     If so indicated in the applicable Prospectus  Supplement,  the Company will
authorize  dealers  acting as the  Company's  agents to  solicit  agreements  by
certain  institutions to purchase the Securities (or Depositary Shares) from the
Company  at the public  offering  price set forth in the  applicable  Prospectus
Supplement  pursuant to delayed delivery contracts  ("Contracts")  providing for
payment and  delivery on the date or dates  stated in a  Prospectus  Supplement.
Each Contract will be for an amount not less than,  and the aggregate  amount of
the Securities (or Depositary  Shares),  based on the liquidation value thereof,
sold pursuant to Contracts will be not less nor more than the respective amounts
stated  in a  Prospectus  Supplement.  Institutions  with whom  Contracts,  when
authorized,  may  be  made  include  commercial  and  savings  banks,  insurance
companies,  pension  funds,  investment  companies,  educational  and charitable
institutions  and other  institutions,  but will in all cases be  subject to the
approval of the Company.  Contracts  will be subject to the  condition  that the
purchase by an institution of the Securities (or Depositary  Shares)  covered by
Contracts  will not at the time of delivery be prohibited  under the laws of any
jurisdiction in the United States to which such institution is subject.

     Any  Securities  issued  hereunder  (other than  Common  Stock) will be new
issues of securities  with no established  trading market.  Any  underwriters or
agents to or through  whom such  Securities  are sold by the  Company for public
offering and sale may make a market in such Securities, but such underwriters or
agents will not be obligated to do so and may discontinue any market at any time
without  notice.  No assurance  can be given as to the  liquidity of the trading
market for any Securities.

     Certain of the underwriters,  dealers or agents and their associates may be
customers of, engage in transactions with, and perform services for, the Company
and certain of its affiliates in the ordinary course of business.

                                    EXPERTS

     The  consolidated  balance sheets as of December 31, 1994 and 1993, and the
consolidated statements of operations,  changes in stockholders' equity and cash
flows and the related  schedules for each of the three years in the period ended
December  31,  1994,  incorporated  into this  Prospectus  and  elsewhere in the
Registration  Statement,  have been audited by Arthur Andersen LLP,  independent
public accountants,  as indicated in their reports with respect thereto, and are
incorporated  herein in reliance  upon the  authority of said firm as experts in
giving said reports.

     With  respect  to the  unaudited  interim  financial  information  for  the
quarters ended March 31, 1995 and 1994,  Arthur Andersen LLP has applied limited
procedures  in  accordance  with  professional  standards  for  review  of  that
information.  However,  their  separate  report thereon states that they did not
audit and they do not express an opinion on that interim financial  information.
Accordingly,  the degree of reliance on their report on that information  should
be restricted in light of the limited nature of the review  procedures  applied.
In addition,  the  accountants  are not subject to the  liability  provisions of
Section  11 of the  Securities  Act of 1933 for their  report on the  unaudtited
interim financial  information because that report is not a "report" or a "part"
of the registration  statement  prepared or certified by the accountants  within
the meaning of Sections 7 and 11 of the Act.

                           VALIDITY OF THE SECURITIES

     The validity of the Securities will be passed upon for the Company by Snell
& Wilmer L.L.P.,  One Arizona  Center,  Phoenix,  Arizona 85004,  counsel to the
Company, and for any underwriters by the counsel named in the
applicable Prospectus Supplement.

                                                             $ 488,966

Item 15.  Indemnification of Directors and Officers.

     The Certificate of Incorporation provides that the directors of the Company
shall be under no liability  to the Company for  monetary  damages for breach of
fiduciary duty as a director of the Company  except for those specific  breaches
and acts or omissions with respect to which the Delaware General Corporation Law
(the "Delaware  Law")  expressly  provides that a  corporation's  certificate of
incorporation shall not eliminate or limit such personal liability of directors.
Section 102(b)(7) of the Delaware Law provides that a corporation's  certificate
of  incorporation  may not limit the  liability of directors for (i) breaches of
their duty of  loyalty to the  corporation  and its  stockholders,  (ii) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law,  (iii)  transactions  from which a director  derives  improper
personal benefit and (iv) unlawful dividends or unlawful stock repurchases under
Section 174 of the Delaware Law.

     Under the Delaware Law,  directors and officers as well as other  employees
and  individuals,  may be indemnified  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts  paid in  settlement  in  connection  with
specified actions, suits or proceedings, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation,  a
"derivative  action"),  if  they  acted  in  good  faith  and in a  manner  they
reasonably  believed to be in or not opposed to the best interest of the Company
and, with respect to any criminal action or proceeding,  had no reasonable cause
to believe their conduct was unlawful.  A similar standard of care is applicable
in the case of a derivative action,  except that indemnification only extends to
expenses  (including  attorneys'  fees)  incurred in connection  with defense or
settlement of such an action and the Delaware Law requires court approval before
there can be any  indemnification  where the person seeking  indemnification has
been found liable to the Company. The Company's By-laws provide that each person
who was or is made a party to, or is involved in, any action, suit or proceeding
by reason of fact that he or she is or was a  director,  officer or  employee of
the  Company  (or was  serving  at the  request of the  Company  as a  director,
officer,  employee or agent for another  entity)  will be  indemnified  and held
harmless by the  Company to the full  extent  authorized  by the  Delaware  Law,
against all expense,  liability or loss (including  attorneys' fees,  judgments,
fines or penalties and amounts to be paid in settlement)  reasonably incurred by
such person in connection  therewith.  The Company's By-laws provide that rights
conferred  thereby are contract  rights and will include the right to be paid by
the Company for the expenses  incurred in defending  the  proceedings  specified
above, in advance of their final  disposition,  except that, if the Delaware Law
so requires,  such payment will only be made upon delivery to the Company by the
indemnified  party of an  undertaking  to repay all amounts so advanced if it is
ultimately determined that the person receiving such payments is not entitled to
be indemnified under such provision or otherwise.  The Company's By-laws provide
that  persons  indemnified  thereunder  may bring suit  against  the  Company to
recover unpaid amounts claimed thereunder,  and that if such suit is successful,
the expense of bringing such a suit will be reimbursed by the Company.

Item 17. Undertakings.

     The undersigned registrant hereby undertakes:

     (1)  To file,  during any period in which offers or sales are being made, a
          post-effective amendment to this registration statement:

             (i)    To include any  prospectus  required by Section  10(a)(3) of
                    the Securities Act of 1933;

             (ii)   To reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change  in the  information  set  forth in the  registration
                    statement.  Notwithstanding  the foregoing,  any increase or
                    decrease  in  volume  of  securities  offered  (if the total
                    dollar  value of  securities  offered  would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of prospectus filed with the Commission pursuant
                    to Rule 424(b) if, in the  aggregate,  the changes in volume
                    and price  represent  no more than 20% change in the maximum
                    aggregate  offering price set forth in the  "Calculation  of
                    Registration  Fee"  table  in  the  effective   registration
                    statement;

             (iii)  To include any material information with respect to the plan
                    of distribution not previously disclosed in the registration
                    statement or any material change to such  information in the
                    registration statement;

provided,  however,  that  paragraphs  (1)(i)  and  (1)(ii)  do not apply if the
registration  statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed by the registrant  pursuant to Section 13 or 15(d) of the
Securities  Exchange  Act of 1934  that are  incorporated  by  reference  in the
registration statement.

     (2)  That,  for  the  purpose  of  determining   any  liability  under  the
          Securities Act of 1933,  each such  post-effective  amendment shall be
          deemed to be a new registration  statement  relating to the securities
          offered  therein,  and the  offering of such  securities  at that time
          shall be deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
          of  the  securities  being  registered  which  remain  unsold  at  the
          termination of the offering.

     The undersigned registrant hereby undertakes:

     (1)  For purposes of determining  any liability under the Securities Act of
          1933,  the  information  omitted from the form of prospectus  filed as
          part of this  registration  statement  in reliance  upon Rule 430A and
          contained in a form of prospectus filed by the registrant  pursuant to
          Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall
          be deemed to be part of this registration  statement as of the time it
          was declared effective.

     (2)  For the purpose of determining  any liability under the Securities Act
          of  1933,  each  post-effective  amendment  that  contains  a form  of
          prospectus shall be deemed to be a new registration statement relating
          to the securities offered therein, and the offering of such securities
          at that  time  shall be deemed to be the  initial  bona fide  offering
          thereof.

     The  undersigned   registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     The undersigned registrant hereby undertakes to file an application for the
purpose of determining  the  eligibility of the trustee to act under  subsection
(a) of section 310 of the Trust  Indenture  Act of 1939 in  accordance  with the
rules and regulations  prescribed by the Commission  under section  305(b)(2) of
the Trust Indenture Act of 1939.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
of  1933  and is,  therefore,  unenforceable.  In the  event  that a  claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act of 1933 and will be governed by the final adjudication of such issue.
