ITEM 5. OTHER EVENTS

     On October 15, 1997,  Coeur d'Alene  Mines  Corporation  (the  "Company")
consummated  the  sale  of  $143,750,000   principal  amount  of  its  7  1/4%
Convertible  Subordinated  Debentures  due 2005 (the  "Debentures")  to Lazard
Freres & Co.  LLC  (the  "Purchaser")  pursuant  to the  terms  of a  Purchase
Agreement,  dated as of October 7, 1997, between the Company and the Purchaser
(the "Purchase Agreement").  That amount includes $18,750,000 principal amount
of the  Debentures  sold by the Company  upon the  Purchaser's  exercise of an
over-allotment option.

     The offering of Debentures was not registered under the Securities Act of
1933 (the "Act") and the Debentures were sold only to "qualified institutional
buyers" in reliance upon Rule 144A under the Act and in offshore  transactions
in accordance  with  Regulation S under the Act and may not be offered or sold
in the United States absent  registration  under,  or the  availability  of an
exception from the registration requirements of, the Act.

     The Debentures  are  convertible  into shares of common stock,  par value
$1.00 per share,  of the Company (the "Common Stock") on or before October 31,
2005, unless previously  redeemed,  at a conversion price of $17.45 per share,
subject to adjustment in certain  events.  The Debentures are  redeemable,  in
whole or in part, at any time on and after October 31, 2000 at the  redemption
prices  set  forth  in the  Indenture,  dated as of  October  15,  1997,  (the
"Indenture")  between the Company and Bankers Trust  Company,  as trustee (the
"Trustee"),   plus  accrued  interest.  The  Debentures  are  required  to  be
repurchased at the option of the holder if a "Designated Event" (as defined in
the Indenture) occurs at 100% of their principal amount plus accrued interest.
The Debentures are unsecured and subordinate in right of payment to all Senior
Debt (as defined in the Indenture) and are also  effectively  subordinated  to
liabilities of the Company's subsidiaries.

     Pursuant  to a  Registration  Rights  Agreement,  dated as of October 15,
1997, between the Company and the Purchaser,  the Company is obligated to file
with the  Securities and Exchange  Commission,  and to use its best efforts to
cause to become effective,  a shelf registration statement covering resales of
the Debentures and the shares of Common Stock issuable upon conversion thereof
and to maintain the effectiveness of such registration statement until October
31, 1999, subject to adjustment in certain circumstances.

     The Company  plans to use  approximately  $42.9  million of the estimated
$138,942,500 net proceeds of the sale of Debentures to repay bank indebtedness
and to use the  balance  of the net  proceeds  for other  corporate  purposes,
including the possible  acquisition of or investment in additional  silver and
gold mining properties or businesses.

     The Trustee may appoint an authenticating agent acceptable to the Company
to  authenticate   Securities.   An  authenticating   agent  may  authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication  by the  Trustee  includes  authentication  by such  agent.  An
authenticating  agent has the same right as an Agent to deal with the  Company
or an Affiliate.

     SECTION 2.03. REGISTRAR,  PAYING AGENT,  CONVERSION AGENT, DEPOSITORY AND
SECURITIES CUSTODIAN. The Company shall maintain in such locations as it shall
determine  (a) an office or  agency  where  securities  may be  presented  for
registration  of  transfer  or for  exchange  ("Registrar"),  (b) an office or
agency where Securities may be presented for payment ("Paying Agent"), and (c)
an  office  or  agency  where  securities  may  be  presented  for  conversion
("Conversion  Agent").  The Registrar  shall keep a register of the Securities
and of their transfer and exchange (the  "Securities  Register").  The Company
may appoint one or more  co-Registrars,  one or more additional  paying agents
and one or more additional conversion agents. The term "Paying Agent" includes
any  additional  paying  agent;  the  term  "Conversion  Agent"  includes  any
additional  conversion  agent.  The  Company  may  change  any  Paying  Agent,
Registrar,  Conversion Agent or co-Registrar without prior notice. The Company
shall notify the Trustee of the name and address of


                                      C-8

any Agent not a party to this  Indenture.  If the Company  fails to appoint or
maintain  another entity as Registrar,  Paying Agent or Conversion  Agent, the
Trustee shall act as such. The Company or any of its  subsidiaries  may act as
Conversion Agent, Paying Agent, Registrar or co-Registrar.

     The Company  initially  appoints The Depository  Trust Company ("DTC") to
act as Depository with respect to the Global Security.

     The Company initially  appoints the Trustee as Conversion  Agent,  Paying
Agent, Registrar and authenticating agent.

     The Company initially appoints Bankers Trust Company to act as Securities
Custodian with respect to the Global Security.

     SECTION  2.04.  PAYING  AGENT TO HOLD MONEY IN TRUST.  The Company  shall
require  each Paying Agent other than the Trustee to agree in writing that the
Paying  Agent  will hold in trust for the  benefit of  Securityholders  or the
Trustee  all money held by the Paying  Agent for the payment of  principal  or
interest on the Securities,  and will notify the Trustee of any default by the
Company in making any such  payment.  While any such  default  continues,  the
Trustee may require a Paying Agent to pay all money held by it to the Trustee.
The Company at any time may require a Paying Agent to pay all money held by it
to the Trustee.  Upon payment over to the Trustee,  the Paying Agent (if other
than the  Company or a  subsidiary)  shall have no further  liability  for the
money. If the Company or a subsidiary acts as Paying Agent, it shall segregate
and hold in a separate trust fund for the benefit of the  Securityholders  all
money held by it as Paying Agent.

     SECTION 2.05.  SECURITYHOLDER  LISTS.  The Trustee  shall  preserve in as
current a form as is reasonably  practicable the most recent list available to
it of the names and  addresses of  Securityholders.  If the Trustee is not the
Registrar, the Company shall furnish to the Trustee on or before each interest
payment  date and at such other  times as the Trustee may request in writing a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Securityholders.

     SECTION 2.06. TRANSFER AND EXCHANGE. (a) The transfer and exchange of the
Global Security shall be effected  through the Depository,  in accordance with
this Indenture  (including the  restrictions on transfer set forth herein) and
the  procedures of the Depository  therefor.  When  Definitive  Securities are
presented to the  Registrar or a  co-Registrar  with a request to register the
transfer  of  such  Definitive  Securities  or  to  exchange  such  Definitive
Securities  for an equal  principal  amount of Definitive  Securities of other
authorized  denominations,  the Registrar or  co-Registrar  shall register the
transfer  or make the  exchange  as  requested  if its  requirements  for such
transaction  are  met;  provided,  HOWEVER,  that  the  Definitive  Securities
surrendered for transfer or exchange (i) shall be duly endorsed or accompanied
by a written  instrument of transfer in form  satisfactory  to the Company and
the  Registrar or  co-Registrar,  duly  executed by the Holder  thereof or his
attorney,  duly  authorized  in  writing  and (ii) in the  case of  Definitive
Securities  which are Restricted  Securities only, shall be accompanied by the
following additional information and documents, as applicable:

     (A) if such Definitive Security is being acquired for the account of such
   Holder,  without transfer,  a certification from such Holder to that effect
   (in substantially the form of Exhibit C-I hereto); or

     (B) if such  Definitive  Security  is being  transferred  to a  qualified
   institutional  buyer (as defined in Rule 144A under the Securities  Act) in
   accordance  with  Rule 144A  under the  Securities  Act or  pursuant  to an
   exemption  from  registration  in  accordance  with  Rules  144  or  145 or
   Regulation  S  under  the  Securities  Act  or  pursuant  to  an  effective
   registration  statement under the Securities  Act, a certification  to that
   effect (in substantially the form of Exhibit C-I hereto); or

     (C) if such  Definitive  Security  is being  transferred  in  reliance on
   another exemption from the registration requirements of the Securities Act,
   a certification  to that effect (in  substantially  the form of Exhibit C-I
   hereto)  and an opinion of Counsel  acceptable  to the  Company  and to the
   Registrar  or  co-  Registrar  to  the  effect  that  such  transfer  is in
   compliance with the Securities Act (in substantially


                                     C-10

  the form of Exhibit C-II hereto).

     To permit the registration of transfers and exchanges,  the Company shall
execute  and the  Trustee  shall  authenticate  Definitive  Securities  at the
Registrar's or co-  Registrar's  request.  No service charge shall be made for
any registration of transfer or exchange,  but the Company may require payment
of a sum sufficient to cover any transfer tax or similar  governmental  charge
payable in connection therewith (other than any such transfer taxes or similar
governmental  charge payable upon exchanges or transfers  pursuant to Sections
2.10,  3.06,  9.05 or  10.02).  The  Registrar  or  co-Registrar  shall not be
required to register  the  transfer of or  exchange  any  Definitive  Security
selected for redemption in whole or in part, except the unredeemed  portion of
any Security being redeemed in part.

     All Securities  issued upon any  registration  of transfer or exchange of
Securities shall be the valid obligations of the Company,  evidencing the same
debt,  and  entitled  to  the  same  benefits  under  this  Indenture,  as the
Securities surrendered upon such registration of transfer or exchange.

     (b) Except as  permitted by the  following  paragraph,  each  certificate
   evidencing  the Global  Security  and the  Definitive  Securities  (and all
   securities issued in exchange  therefor or substitution  thereof (shares of
   Common Stock issued upon conversion of any Restricted Security shall bear a
   comparable  legend))  shall bear a legend in  substantially  the  following
   form:

          THIS SECURITY AND ANY COMMON STOCK ISSUABLE UPON ITS CONVERSION HAVE
     NOT BEEN  REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED (THE
     "SECURITIES  ACT"),  AND MAY NOT BE OFFERED,  SOLD,  PLEDGED OR OTHERWISE
     TRANSFERRED EXCEPT (A)(1) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES
     IS A QUALIFIED  INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER
     THE SECURITIES  ACT, (2) IN AN OFFSHORE  TRANSACTION  COMPLYING WITH RULE
     903 OR 904 OF REGULATION S UNDER THE  SECURITIES  ACT, (3) PURSUANT TO AN
     EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT
     (IF  AVAILABLE)  OR (4) PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT
     UNDER  THE  SECURITIES  ACT


                                     C-11

     AND (B) IN ACCORDANCE  WITH ALL APPLICABLE  SECURITIES LAWS OF THE STATES
     OF THE UNITED STATES.

     Upon any sale or other transfer of a Restricted  Security  (including the
Global  Security)  satisfying  the  conditions  set forth in clause (3) or (4)
above, or with respect to any Restricted Security that may be sold pursuant to
Rule  144(k)  promulgated  under the  Securities  Act,  (i) in the case of any
Definitive  Security  that  is  a  Restricted   Security,   the  Registrar  or
co-Registrar  shall  permit the Holder  thereof to  exchange  such  Restricted
Security for Definitive Securities that do not bear the legend set forth above
and rescind any  restriction on the transfer of such  Security,  (ii) any such
Restricted Security represented by the Global Security shall not be subject to
any restriction on transfer set forth above;  PROVIDED,  HOWEVER, with respect
to any  request  for an exchange of a  Restricted  Security  for a  Definitive
Security which does not bear a legend,  which request is made in reliance upon
Rule 144(k),  the Holder  thereof shall certify in writing to the Registrar or
co-Registrar that such request is so being made in reliance on Rule 144(k).

     (c)  Notwithstanding  any other provisions (other than the provisions set
   forth in Sections 2.06(d) and 2.06(e) of this Section), the Global Security
   may not be transferred  except as a whole by the Depository to a nominee of
   the  Depository  or by a nominee of the  Depository  to the  Depository  or
   another  nominee of the Depository or by the Depository or any such nominee
   to a successor Depository or a nominee of such successor Depository.

     (d) If at any time the Depository for the Securities notifies the Company
   that  it  is  unwilling  or  unable  to  continue  as  Depository  for  the
   Securities,  the Company shall appoint a successor  Depository with respect
   to the  Securities.  If a successor  Depository  for the  securities is not
   appointed  by the Company  within 90 days after the Company  receives  such
   notice,  the Company  will  execute,  and the  Trustee,  upon receipt of an
   Officers'  Certificate  for the  authentication  and delivery of Definitive
   Securities,  will authenticate and deliver  Definitive  securities in fully
   registered  form in an aggregate  principal  amount equal to the  principal
   amount of the Global Security in exchange for such Global Security.


                                     C-12

<PAGE>

     The Company may at any time and in its sole discretion determine that the
Securities  issued as a Global Security shall no longer be represented by such
Global Security. In such event the Company will execute, and the Trustee, upon
receipt of an Officers'  Certificate  for the  authentication  and delivery of
Definitive Securities, will authenticate and deliver, Definitive Securities in
an  aggregate  principal  amount equal to the  principal  amount of the Global
Security in exchange for such Global Security.

     If a  Definitive  Security is issued in  exchange  for any portion of the
Global Security after the close of business at the office or agency where such
exchange  occurs on any record date and before the opening of business at such
office or agency on the next succeeding  interest payment date,  interest will
not be payable on such  interest  payment  date in respect of such  Definitive
Security, but will be payable on such interest payment date only to the person
to whom interest in respect of such portion of the Global  Security is payable
in accordance with the provisions of this Indenture.

     Definitive Securities issued in exchange for the Global Security pursuant
to this Section 2.06 shall be registered in such names and in such  authorized
denominations as the Depository,  pursuant to instructions  from its direct or
indirect  participants or otherwise,  shall instruct the Trustee.  The Trustee
shall  deliver such  Definitive  Securities to the persons in whose names such
Securities are so registered.

     (e) Any person  having a beneficial  interest in the Global  Security may
   upon request  exchange its interest in the Global Security for a Definitive
   Security. Upon receipt by the Trustee of written or electronic instructions
   from the  Depository  or its  nominee  on  behalf  of any  person  having a
   beneficial  interest  in  Securities  and upon  receipt by the Trustee of a
   written  order of the  Depository  or its nominee  containing  registration
   instructions and, in the case of Restricted  Securities only, the following
   additional information and documents:

     (i) if such Definitive Security is being acquired for the account of such
    person,  without transfer, a certification from such person to that effect
    (in


                                     C-13


<PAGE>

    substantially the form of Exhibit C-I hereto); or

     (ii) if such  Definitive  Security  is being  transferred  to a qualified
    institutional  buyer (as defined in Rule 144A under the Securities Act) in
    accordance  with Rule 144A  under the  Securities  Act or  pursuant  to an
    exemption  from  registration  in  accordance  with  Rules  144  or 145 or
    Regulation  S  under  the  Securities  Act  or  pursuant  to an  effective
    registration  statement under the Securities Act, a certification  to that
    effect (in substantially the form of Exhibit C-I hereto); or

     (iii) if such  Definitive  Security is being  transferred  in reliance on
    another  exemption from the  registration  requirements  of the Securities
    Act, a certification to that effect (in  substantially the form of Exhibit
    C-I hereto) and an opinion of Counsel acceptable to the Company and to the
    Registrar  or co-  Registrar  to  the  effect  that  such  transfer  is in
    compliance with the Securities Act (in  substantially  the form of Exhibit
    C-II hereto);

the Trustee or the Securities Custodian, at the direction of the Trustee, will
cause, in accordance with the standing  instructions  and procedures  existing
between the Depository and the Securities  Custodian,  the aggregate principal
amount of the Global Security to be reduced and, following such reduction, the
Company will execute and, upon receipt of an authentication  order in the form
of an Officers' Certificate, the Trustee will authenticate and deliver to such
person or the transferee, as the case may be, a Definitive Security.

     (f) A holder of a  Definitive  Security  may,  upon  satisfaction  of the
   requirements  set forth below,  exchange  such  Definitive  Security for an
   interest  in  the  Global  Security.  Upon  receipt  by  the  Trustee  of a
   Definitive   Security,   duly  endorsed  or   accompanied   by  appropriate
   instruments endorsed or accompanied by appropriate instruments of transfer,
   in form  satisfactory  to the  Trustee,  together  with (i)  certification,
   substantially  in the form of  Exhibit  C-I  hereto,  that such  Definitive
   Security  is being  transferred  to a  qualified  institutional  buyer  (as
   defined in Rule 144A under the Securities Act) in accordance with Rule 144A
   under the Securities Act, and


                                     C-14

<PAGE>

   (ii) written  instructions  directing the Trustee to make, or to direct the
   Securities  Custodian to make,  an  endorsement  on the Global  Security to
   reflect an increase in the  aggregate  principal  amount of the  Securities
   represented  by  the  Global  Security,   the  Trustee  shall  cancel  such
   Definitive Security and cause, or direct the Securities Custodian to cause,
   in  accordance  with the  standing  instructions  and  procedures  existing
   between  the  Depository  and  the  Securities  Custodian,   the  aggregate
   principal  amount of Securities  represented  by the Global  Security to be
   increased accordingly.

     (g) At such time as all interests in the Global Security have either been
   exchanged for Definitive Securities,  redeemed,  converted,  repurchased or
   canceled,  such Global  Security  shall be canceled by the Trustee.  At any
   time prior to such  cancelation,  if any interest in the Global Security is
   exchanged for Definitive Securities,  redeemed,  converted,  repurchased or
   canceled,  the principal  amount of Securities  represented  by such Global
   Security shall be reduced and an  endorsement  shall be made on such Global
   Security, by the Trustee or the Securities  Custodian,  at the direction of
   the Trustee, to reflect such reduction.

     (h) The Company shall not be required (i) to issue, register the transfer
   of or  exchange  Securities  during a period  beginning  at the  opening of
   business  15  days  before  the  day of any  selection  of  Securities  for
   redemption  under  Section  3.02 and ending at the close of business on the
   day of  selection,  or (ii) to  register  the  transfer  or exchange of any
   Security  so  selected  for  redemption  in whole or in  part,  except  the
   unredeemed portion of any Security being redeemed in part.

     SECTION  2.07.  REPLACEMENT  SECURITIES.  If any  mutilated  Security  is
surrendered  to the Trustee,  the Company  shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

     If there shall be  delivered  to the Company and the Trustee (a) evidence
to their  satisfaction of the  destruction,  loss or theft of any Security and
(b) such security or indemnity as may be required by them to save each of them
and any agent of either of them  harmless,  then,


                                     C-15

<PAGE>

in the absence of notice to the Company or the Trustee that such  Security has
been acquired by a bona fide purchaser, the Company shall execute and upon its
request  the  Trustee  shall  authenticate  and  deliver,  in lieu of any such
destroyed, lost or stolen Security, a new Security of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and  payable,  the  Company in its  discretion  may,
instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge  that  may be  imposed  in  relation  thereto  and any  other  expenses
(including the fees and expenses of the Trustee) connected therewith.

     Every  new  security  issued  pursuant  to  this  Section  in lieu of any
destroyed,  lost or stolen  Security shall  constitute an original  additional
contractual obligation of the Company,  whether or not the destroyed,  lost or
stolen  Security  shall be at any time  enforceable  by  anyone,  and shall be
entitled to all the  benefits of this  Indenture  equally and  proportionately
with any and all other Securities duly issued hereunder.

     The  provisions of this Section are exclusive and shall  preclude (to the
extent  lawful) all other rights and remedies with respect to the  replacement
or payment of mutilated, destroyed, lost or stolen securities.

     SECTION 2.08. OUTSTANDING  SECURITIES.  The Securities outstanding at any
time are all the  Securities  authenticated  by the  Trustee  except for those
canceled by it, those delivered to it for cancelation and those  reductions in
the interests in the Global Security  effected by the Trustee  hereunder,  and
those described in this Section as not outstanding.

     If a Security  is  replaced  pursuant  to Section  2.07,  it ceases to be
outstanding  unless the Trustee  receives  proof  satisfactory  to it that the
replaced Security is held by a bona fide purchaser.


                                     C-16

<PAGE>

     If Securities  are considered  paid under Section 4.01,  they cease to be
outstanding and interest on them ceases to accrue.

     A Security  does not cease to be  outstanding  because  the Company or an
Affiliate of the Company holds the Security.

     SECTION 2.09. TREASURY SECURITIES.  In determining whether the Holders of
the required  principal  amount of Securities have concurred in any direction,
waiver or  consent,  Securities  owned by the Company or an  Affiliate  of the
Company shall be considered  as though they are not  outstanding,  except that
for the  purposes of  determining  whether the Trustee  shall be  protected in
relying on any such direction,  waiver or consent,  only Securities  which any
Corporate Trust Officer knows are so owned shall be so disregarded.

     SECTION  2.10.  TEMPORARY  SECURITIES.   Until  the  Global  Security  or
Definitive Securities are ready for delivery,  the Company may prepare and the
Trustee shall authenticate temporary Securities. Temporary Securities shall be
substantially in the form of the Global Security or Definitive Securities,  as
the  case  may  be,  but  may  have  variations  that  the  Company  considers
appropriate for temporary Securities.  Without unreasonable delay, the Company
shall  prepare  and the  Trustee  shall  authenticate  the Global  Security or
Definitive  Securities,  as  the  case  may  be,  in  exchange  for  temporary
Securities.

     SECTION 2.11. CANCELATION. The Company at any time may deliver Securities
to the Trustee for  cancelation.  The  Registrar,  Paying Agent and Conversion
Agent  shall  forward to the Trustee any  Securities  surrendered  to them for
registration of transfer,  exchange,  payment or conversion. The Trustee shall
cancel all Securities  surrendered  for  registration  of transfer,  exchange,
payment,  replacement,   conversion  or  cancellation  and  shall  dispose  of
cancelled  Securities.  The  Company may not issue new  Securities  to replace
Securities  that it has paid or that have been  delivered  to the  Trustee for
cancelation or that any Securityholder has converted pursuant to Article X.

     SECTION 2.12. DEFAULTED INTEREST.  If the Company


                                     C-17

<PAGE>

fails to make a  payment  of  interest  on the  Securities,  it shall pay such
defaulted  interest plus any interest payable on the defaulted interest in any
lawful  manner.  It may pay such  defaulted  interest,  plus any such interest
payable on it, to the persons who are  Securityholders on a subsequent special
record date.  The Company  shall fix any such record date and payment date. At
least  15 days  before  any  such  record  date,  the  Company  shall  mail to
Securityholders a notice that states the record date, payment date, and amount
of such interest to be paid.


                                  ARTICLE III

                                  REDEMPTION

     SECTION  3.01.  NOTICES  TO  TRUSTEE.  If the  Company  elects  to redeem
Securities  pursuant to the optional  redemption  provisions of paragraph 6 of
the  Securities,  it shall notify the Trustee of the  Redemption  Date and the
principal amount of Securities to be redeemed.

     The Company  shall give each notice  provided  for in this Section to the
Trustee at least 40 days but not more than 60 days before the Redemption  Date
(unless a shorter notice period shall be satisfactory to the Trustee).

     SECTION 3.02.  SELECTION OF  SECURITIES TO BE REDEEMED.  If less than all
the Securities are to be redeemed,  the Trustee shall select the Securities to
be redeemed by lot or by a method that complies with the  requirements  of any
exchange on which the  Securities  are listed and that the  Trustee  considers
fair and  appropriate.  The Trustee may select for redemption  portions of the
principal of Securities that have denominations larger than $1,000. Securities
and  portions  of them it selects  shall be in  amounts of $1,000 or  integral
multiples  of $1,000.  The Trustee  shall  notify the Company  promptly of the
Securities or portions of Securities to be called for redemption.

     SECTION 3.03. NOTICE OF REDEMPTION. At least 30 days but not more than 60
days before a Redemption  Date,  the Company shall mail a notice of redemption
to each  Holder  whose  Securities  are to be  redeemed at the address of such
Holder shown in the Security Register.


                                     C-18

<PAGE>

     The notice shall identify the Securities to be redeemed and shall state:

     (a) the Redemption Date;

     (b) the Redemption Price;

     (c) if any  Security  is being  redeemed  in  part,  the  portion  of the
   principal  amount of such  Security  to be  redeemed  and  that,  after the
   Redemption  Date,  upon  surrender  of such  Security,  a new  Security  or
   securities  in  principal  amount equal to the  unredeemed  portion will be
   issued;

     (d) the conversion price;

     (e) the name and address of the Paying Agent and Conversion Agent;

     (f) that  Securities  called for  redemption may be converted at any time
   before the close of  business  on the  business  day before the  Redemption
   Date;

     (g)  that  Holders  who  want to  convert  Securities  must  satisfy  the
   requirements in paragraph 9 of the Securities;

     (h) that  Securities  called for  redemption  must be  surrendered to the
   Paying Agent to collect the Redemption Price;

     (i) that interest on Securities called for redemption ceases to accrue on
   and after the Redemption Date; and

     (j) that Holders who convert after the date of the redemption  notice but
   before the Redemption Date will be entitled to receive accrued  interest on
   their converted Securities through the Redemption Date.

     At the Company's request,  the Trustee shall give notice of redemption in
the Company's name and at its expense.

     SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION. Once a notice of redemption
is mailed,  Securities  called for


                                     C-19


<PAGE>

redemption  become  due and  payable on the  Redemption  Date at the price set
forth in the Security.

     SECTION 3.05.  DEPOSIT OF REDEMPTION  PRICE.  On or before the Redemption
Date,  the Company  shall  deposit  with the Trustee or with the Paying  Agent
money  sufficient to pay the Redemption  Price of and accrued  interest on all
Securities to be redeemed on that date.  The Trustee or the Paying Agent shall
return to the Company any money not required for that purpose.

     SECTION 3.06. SECURITIES REDEEMED IN PART. Upon surrender of a Definitive
Security  that is  redeemed in part,  the Company  shall issue and the Trustee
shall  authenticate  for  the  Holder  at the  expense  of the  Company  a new
Definitive Security equal in principal amount to the unredeemed portion of the
Definitive Security surrendered.


                                  ARTICLE IV

                                   COVENANTS

     SECTION 4.01. PAYMENT OF SECURITIES.  The Company shall pay the principal
of and interest on the  Securities on the dates and in the manner  provided in
the  Securities.  Principal and interest shall be considered  paid on the date
due if the Paying Agent (other than the Company or a subsidiary) holds on that
date money  designated  for and  sufficient  to pay all principal and interest
then due;  PROVIDED,  HOWEVER,  that money  held by the  Paying  Agent for the
benefit of holders of Senior  Debt  pursuant to the  provisions  of Article XI
hereof shall not be considered paid within the meaning of this Section 4.01.

     To the  extent  lawful,  the  Company  shall  pay  interest  semiannually
(including  post-petition  interest in any  proceeding  under any  bankruptcy,
insolvency or other similar law) on (a) overdue  principal,  at the rate borne
by the Securities and (b) overdue installments of interest (including interest
contemplated by clause (a) and without regard to any applicable  grace period)

and its subsidiaries  during the preceding fiscal year has been made under the
supervision  of the signing  Officers with a view to  determining  whether the
Company has kept, observed, performed and fulfilled its obligations under this
Indenture,  and  further  stating,  as  to  each  such  officer  signing  such
certificate, that to the best of his knowledge the Company has kept, observed,
performed and fulfilled  each and every  covenant  contained in this Indenture
and is not in default in the  performance  or  observance of any of the terms,

     The first  certificate  pursuant to this Section  shall be for the fiscal
year ending on December 31, 1997.

     The  Company  will,  so long as any of the  Securities  are  outstanding,
deliver to the Trustee,  forthwith upon becoming aware of any Default or Event
of Default,  an  Officers'  Certificate  specifying  such  Default or Event of
Default.

     SECTION 4.04. STAY,  EXTENSION AND USURY LAWS. The Company  covenants (to
the extent  that it may  lawfully  do so) that it will not at any time  insist
upon,  plead,  or in any  manner  whatsoever  claim  or take  the  benefit  or
advantage of, any stay, extension or usury law wherever enacted, now or at any
time hereafter in force,  which may affect the 


                                     C-21

<PAGE>

covenants or the performance of this Indenture; and the Company (to the extent
it may lawfully do so) hereby expressly waives all benefit or advantage of any
such law, and covenants  that it will not, by resort to any such law,  hinder,
delay or impede the execution of any power herein granted to the Trustee,  but
will suffer and permit the execution of every such power as though no such law
has been enacted.

     SECTION  4.05.  LIQUIDATION.  The  Company  shall  not  adopt any plan of

preceded by, (a) the sale,  lease,  conveyance or other  disposition of all or
substantially all the assets of the Company otherwise than substantially as an
entirety  in  accordance  with  Article V and (b) the  distribution  of all or
substantially  all the  proceeds  of such  sale,  lease,  conveyance  or other
disposition  and of the  remaining  assets of the Company to holders of Common
Stock of the Company, unless the Company shall in connection with the adoption
of such plan make provision for, or agree that prior to making any liquidating
distributions  it will make provision for, the  satisfaction  of the Company's
obligations  hereunder and under the Securities as to the payment of principal
and interest.

     SECTION  4.06.  RESERVATION  OF SHARES OF COMMON STOCK FOR ISSUANCE  UPON
CONVERSION.  The Company  will at all times cause there to be  authorized  and

     SECTION  5.01.  WHEN  COMPANY  MAY  MERGE,  ETC.  The  Company  shall not
consolidate  with or merge into any other  corporation or convey,  transfer or
lease its  properties and assets  substantially  as an entirety to any person,

   Company is merged or the person which  acquires by  conveyance or transfer,
   or which leases, the properties and assets of the Company  substantially as
   an entirety shall be a corporation organized and existing under the laws of
   the United States of America, any State thereof or the District of Columbia
   and shall expressly assume, by an indenture  supplemental hereto,  executed
   and delivered to the Trustee, in form satisfactory to the Trustee,  the due
   and punctual payment of the principal of and interest on all the Securities
   and the  performance of every covenant of this Indenture on the part of the
   Company to be performed or observed and shall have provided for  conversion

     (c) the Company has delivered to the Trustee an Officers' Certificate and
   an  opinion of  Counsel,  each  stating  that such  consolidation,  merger,

   to such transaction have been complied with.

     SECTION 5.02. SUCCESSOR CORPORATION  SUBSTITUTED.  Upon any consolidation
or merger,  or any sale,  lease,  conveyance  or other  disposition  of all or
substantially  all of the assets of the  Company in  accordance  with  Section

                                     C-23

<PAGE>

consolidation  or into or with  which the  Company  is merged or to which such
sale, lease,  conveyance or other disposition is made shall succeed to, and be
substituted  for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor person has been named

case of a sale,  lease,  conveyance or other disposition shall not be released
from the obligation to pay the principal of and interest on the Securities.


                                  ARTICLE VI

                             DEFAULTS AND REMEDIES

     SECTION 6.01. EVENTS OF DEFAULT. An "Event of Default" occurs if:

     (a) the Company  defaults in the payment of interest on any Security when
   the same becomes due and payable and the Default  continues for a period of
   30 days;

     (b) the Company  defaults in the payment of the principal of any Security
   when the same  becomes  due and payable at  maturity,  upon  redemption  or
   otherwise;

     (c) the  Company  defaults  in the  payment  of the  repurchase  price in
   respect of any Security on the Repurchase  Date therefor in accordance with
   the provisions of Article XII, whether or not such payment is prohibited by
   the provisions of Article XI;

     (d) the Company defaults in the performance of, or breaches, any covenant
   or  warranty  of the  Company in this  Indenture  (other than a covenant or
   warranty a default in whose  performance  or whose  breach is  elsewhere in
   this Section specifically dealt with), and such default or breach continues
   for a period  of 60 days  after  there has been  given,  by  registered  or
   certified  mail,  to the  Company by the  Trustee or to the Company and the
   Trustee  by the  Holders  of at least 25% in  principal  amount of the then
   outstanding  Securities a written notice  specifying such default or breach
   and requiring it to be remedied and stating that such


                                     C-24

<PAGE>

   notice is a "Notice of Default" hereunder;

     (e) the  Company  defaults  under  any  bond,  debenture,  note or  other
   evidence  of  indebtedness  for money  borrowed by the Company or under any
   mortgage,  indenture  or  instrument  under which there may be issued or by
   which there may be secured or evidenced any indebtedness for money borrowed
   by the Company,  whether such indebtedness now exists or shall hereafter be
   created,  which  default  shall have resulted in $1,000,000 or more of such
   indebtedness  becoming or being  declared due and payable prior to the date
   on which it would  otherwise  have  become due and  payable,  without  such
   indebtedness having been discharged,  or acceleration having been rescinded
   or annulled,  within a period of 10 days after there shall have been given,
   by  registered  or certified  mail, to the Company by the Trustee or to the
   Company and the Trustee by the Holders of at least 25% in principal  amount
   of the then outstanding Securities a written notice specifying such default
   and  requiring the Company to cause such  indebtedness  to be discharged or
   cause such  acceleration  to be rescinded or annulled and stating that such
   notice is a "Notice of Default" hereunder; or

     (f) the Company or any Significant  Subsidiary shall commence a voluntary
   case or  other  proceeding  seeking  liquidation,  reorganization  or other
   relief with respect to itself or its debts under any bankruptcy, insolvency
   or other similar law now or hereafter in effect, or seeking the appointment
   of a trustee, receiver, conservator, liquidator, custodian or other similar
   official of it or any substantial part of its property, or shall consent to
   any such relief or to the  appointment  of or taking of  possession  by any
   such official in an involuntary case or other proceeding  commenced against
   it or shall file an answer admitting the material allegations against it in
   any such proceeding,  or shall make a general assignment for the benefit of
   creditors,  or shall  take any  corporate  action to  authorize  any of the
   foregoing,  or becomes  unable or fails  generally to pay its debts as they
   become due; or an involuntary  case or other  proceeding shall be commenced
   against  the Company or any  Significant  Subsidiary  seeking  liquidation,
   reorganization or other relief with respect to it or


                                     C-25

<PAGE>

   its debts  under any  bankruptcy,  insolvency  or other  similar law now or
   thereafter  in effect or seeking the  appointment  of a trustee,  receiver,
   conservator,  liquidator,  custodian or other similar official of it or any
   substantial  part of its  property,  and  such  involuntary  case or  other
   proceeding  shall  remain  undismissed  and  unstayed  for a  period  of 90
   consecutive days.

     In the case of any Event of Default  pursuant to the  provisions  of this
   Section 6.01  occurring by reason of any wilful action (or inaction)  taken
   (or not  taken)  by or on  behalf  of the  Company  with the  intention  of
   avoiding  payment of the premium which the Company would have had to pay if
   the Company then had elected to redeem the Securities pursuant to paragraph
   6 of the  Securities,  an  equivalent  premium  shall  also  become  and be
   immediately  due and payable to the extent  permitted  by law,  anything in
   this   Indenture   or  in  the   Securities   contained   to  the  contrary
   notwithstanding.

     SECTION 6.02.  ACCELERATION.  If an Event of Default (other than an Event
of Default  specified in clause (f) of Section 6.01) occurs and is continuing,
the  Trustee  by  notice to the  Company,  or the  Holders  of at least 25% in
principal amount of the then  outstanding  Securities by notice to the Company
and the Trustee,  may declare the unpaid  principal of and accrued interest on
all the Securities to be due and payable.  Upon such declaration the principal
and  interest  shall be due and  payable  immediately.  If an Event of Default
specified  in clause (f) of Section  6.01  occurs,  such an amount  shall ipso
facto become and be  immediately  due and payable  without any  declaration or
other act on the part of the Trustee or any Holder.  The Holders of a majority
in  principal  amount  of the then  outstanding  Securities  by  notice to the
Trustee may rescind an  acceleration  and its  consequences  if the rescission
would not conflict  with any judgment or decree and if all existing  Events of
Default have been cured or waived  except  nonpayment of principal or interest
that has become due solely because of the acceleration.

     SECTION  6.03.  OTHER  REMEDIES.  If an Event of  Default  occurs  and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest on the  Securities or to enforce the  performance  of


                                     C-26

<PAGE>

any provision of the Securities or this Indenture.

     The Trustee may maintain a proceeding  even if it does not possess any of
the Securities or does not produce any of them in the  proceeding.  A delay or
omission  by the  Trustee or any  Securityholder  in  exercising  any right or
remedy  accruing upon an Event of Default shall not impair the right or remedy
or  constitute  a waiver  of or  acquiescence  in the  Event of  Default.  All
remedies are cumulative to the extent permitted by law.

     SECTION  6.04.  WAIVER OF PAST  DEFAULTS.  Subject to Section  9.02,  the
Holders of a majority in principal amount of the then  outstanding  Securities
by notice to the Trustee may waive an existing Default or Event of Default and
its  consequences  except a  continuing  Default  or Event of  Default  in the
payment of the principal  (other than principal due by reason of acceleration)
of or interest on any Security or a Default  which  materially  and  adversely
affects the rights of any Holders under Article X.

     SECTION 6.05. CONTROL BY MAJORITY. The Holders of a majority in principal
amount of the then  outstanding  Securities  may direct  the time,  method and
place of conducting any proceeding for any remedy  available to the Trustee or
exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this  Indenture,  is unduly
prejudicial  to the  rights of other  Securityholders,  or would  involve  the
Trustee in personal liability.

     SECTION 6.06.  LIMITATION ON SUITS. A Securityholder  may pursue a remedy
with respect to this Indenture or the Securities only if:

     (a) the  Holder  gives to the  Trustee  notice of a  continuing  Event of
   Default;

     (b)  the  Holders  of at  least  25% in  principal  amount  of  the  then
   outstanding Securities make a request to the Trustee to pursue the remedy;

     (c) such Holder or Holders offer to the Trustee indemnity satisfactory to
   the Trustee against any loss, liability or expense;


                                     C-27

<PAGE>

     (d) the Trustee  does not comply  with the  request  within 60 days after
   receipt of the request and the offer of indemnity; and

     (e) during  such 60-day  period the  Holders of a majority  in  principal
   amount  of the  then  outstanding  Securities  do not give  the  Trustee  a
   direction inconsistent with the request.

A Securityholder may not use this Indenture to prejudice the rights of another
Securityholder   or  to  obtain  a   preference   or  priority   over  another
Securityholder.

     SECTION 6.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT.  Notwithstanding  any
other  provision of this  Indenture,  the right of any Holder of a Security to
receive  payment of principal  and interest on the  Security,  on or after the
respective  due dates  expressed  in the  Security,  or to bring  suit for the
enforcement of any such payment on or after such respective  dates,  shall not
be impaired or affected without the consent of the Holder.

     Notwithstanding  any other provision of this Indenture,  the right of any
Holder of a  Security  (a) to bring suit for the  enforcement  of the right to
convert the Security and (b) to require the Company to repurchase the Security
pursuant to Article XII, shall not be impaired or affected without the consent
of the Holder.

     SECTION  6.08.  COLLECTION  SUIT  BY  TRUSTEE.  If an  Event  of  Default
specified in Section 6.01(a), (b) or (c) occurs and is continuing, the Trustee
may  recover  judgment  in its own name and as  trustee  of an  express  trust
against the Company for the whole amount of principal  and interest  remaining
unpaid on the  Securities  and interest on overdue  principal and interest and
such  further  amount as shall be  sufficient  to cover the costs and,  to the
extent lawful, expenses of collection,  including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

     SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Securityholders  allowed in
any  judicial  proceedings  relative


                                     C-28

<PAGE>

to the Company, its creditors or its property.  Nothing contained herein shall
be deemed to  authorize  the Trustee to  authorize  or consent to or accept or
adopt on behalf of any Securityholder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
thereof,  or to  authorize  the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding.

     SECTION 6.10.  PRIORITIES.  If the Trustee collects any money pursuant to
this Article, it shall pay out the money in the following order:


               FIRST,        to the Trustee for amounts due under
                             Section 7.07;

               SECOND,       to holders of Senior Debt to the extent  required
                             by Article XI;

               THIRD,        to Securityholders  for amounts due and unpaid on
                             the  Securities  for  principal,   and  interest,
                             ratably,  without  preference  or priority of any
                             kind, according to the amounts due and payable on
                             the  Securities  for  principal,   and  interest,
                             respectively; and

               FOURTH,       to the Company.

     The Trustee  may fix a record  date and  payment  date for any payment to
Securityholders other than as provided for in Section 2.12.

     SECTION 6.11.  UNDERTAKING  FOR COSTS. In any suit for the enforcement of
any right or remedy  under this  Indenture  or in any suit against the Trustee
for any action taken or omitted by it as a Trustee,  a court in its discretion
may require the filing by any  litigant in the suit of an  undertaking  to pay
the costs of the suit, and the court in its  discretion may assess  reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the  party  litigant.  This  Section  does not  apply to a suit by the
Trustee,  a suit by a Holder pursuant to Section 6.07, or a suit by Holders of
more than 10% in principal amount of the 


                                     C-29

<PAGE>

then outstanding Securities.


                                  ARTICLE VII

                                    TRUSTEE

     SECTION 7.01. DUTIES OF TRUSTEE.  (a) If an Event of Default has occurred
and is  continuing,  the Trustee shall  exercise such of the rights and powers
vested in it by this  Indenture,  and use the same degree of care and skill in
their exercise, as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs.

     (b) Except during the continuance of an Event of Default:

     (i) the Trustee need perform only those duties that are  specifically set
    forth in this Indenture and no others; and

     (ii)  in  the  absence  of  bad  faith  on  its  part,  the  Trustee  may
    conclusively  rely, as to the truth of the statements and the  correctness
    of the opinions expressed therein, upon certificates or opinions furnished
    to the Trustee  and  conforming  to the  requirements  of this  Indenture.
    However,  the Trustee  shall  examine  the  certificates  and  opinions to
    determine  whether  or not  they  conform  to  the  requirements  of  this
    Indenture;  PROVIDED HOWEVER,  that the Trustee is not required to confirm
    the correctness of any mathematical computations.

     (c) The Trustee may not be relieved from  liability for its own negligent
   action,  its own  negligent  failure to act, or its own wilful  misconduct,
   except that:

     (i) this  paragraph  does not limit the effect of  paragraph  (b) of this
    Section;

     (ii) the Trustee  shall not be liable for any error of  judgment  made in
    good faith by a Trust  Officer,  unless it is proved  that the Trustee was
    negligent in ascertaining the pertinent facts; and

     (iii) the Trustee shall not be liable with respect


                                     C-30

<PAGE>

   to any action it takes or omits to take in good faith in accordance  with a
   direction received by it pursuant to Section 6.05.

     (d) Every  provision  of this  Indenture  that in any way  relates to the
   Trustee is subject to paragraphs (a), (b) and (c) of this Section.

     (e) The Trustee  may refuse to perform any duty or exercise  any right or
   power  unless it receives  indemnity  satisfactory  to it against any loss,
   liability or expense.

     (f) The Trustee shall not be liable for interest on any money received by
   it except as the Trustee may agree in writing with the Company.  Money held
   in trust by the Trustee need not be  segregated  from other funds except to
   the extent required by law.

     SECTION 7.02. RIGHTS OF TRUSTEE. (a) The Trustee may rely on any document
believed  by it to be  genuine  and to have been  signed or  presented  by the
proper person.  The Trustee need not  investigate any fact or matter stated in
the document.

     (b) Before the Trustee acts or refrains  from  acting,  it may require an
   Officers'  Certificate or an Opinion of Counsel, or both. The Trustee shall
   not be liable  for any  action  it takes or omits to take in good  faith in
   reliance on such Officers' Certificate or Opinion of Counsel.

     (c) The Trustee may act through agents, attorneys, custodians or nominees
   and shall not be responsible for the misconduct or negligence of any agent,
   attorney, custodian or nominee appointed with due care.

     (d) The  Trustee  shall not be liable for any action it takes or omits to
   take in good faith which it believes to be  authorized or within its rights
   or powers.

     SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual
or any other  capacity may become the owner or pledgee of  Securities  and may
otherwise  deal with the Company or an Affiliate with the same rights it would
have if it were not  Trustee.  Any Agent  may do the same  with  like  rights.
However, the Trustee is subject to


                                     C-31

<PAGE>

Sections 7.10 and 7.11.

     SECTION 7.04. TRUSTEE'S  DISCLAIMER.  The Trustee makes no representation
as to the validity or adequacy of this Indenture or the  Securities,  it shall
not be accountable  for the Company's use of the proceeds from the Securities,
and it shall  not be  responsible  for any  statement  of the  Company  in the
Indenture or any statement in the Securities other than its authentication.

     SECTION 7.05. NOTICE OF DEFAULTS. If a Default or Event of Default occurs
and is continuing and if it is known to the Trustee, the Trustee shall mail to
Securityholders,  at the name and  address  which  appears  in the  Securities
Register a notice of the  Default or Event of Default  within 90 days after it
occurs.  Except in the case of a Default or Event of Default in payment on any
Security  (including  any  failure to make any  mandatory  redemption  payment
required  hereunder),  the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith  determines that withholding the
notice is in the interests of Securityholders.

     SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS.  This Section 7.06 shall not
be operative as part of this Indenture until this Indenture is qualified under
the TIA, and, until such  qualification,  this Indenture shall be construed as
if this Section 7.06 were not contained herein.

     Within 60 days after the  reporting  date  (which  shall be October 31 of
each year),  the Trustee  shall mail to each  Securityholder,  at the name and
address  which appears in the  Securities  Register a brief report dated as of
such reporting date that complies with TIA ss. 313(a).  The Trustee also shall
comply with TIA ss.  313(b)(2).  The Trustee  shall also  transmit by mail all
reports as required by TIA ss. 313(c).

     A copy of each report at the time of its mailing to Securityholders shall
be filed  with the SEC and each stock  exchange  on which the  Securities  are
listed. The Company shall notify the Trustee when the Securities are listed on
any stock exchange.

     SECTION 7.07.  COMPENSATION  AND INDEMNITY.  The Company shall pay to the
Trustee from time to time 


                                     C-32

<PAGE>

reasonable compensation for its services hereunder. The Trustee's compensation
shall not be  limited  by any law on  compensation  of a trustee of an express
trust. The Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket   expenses  incurred  by  it.  Such  expenses  may  include  the
reasonable compensation and out-of-pocket expenses of the Trustee's agents and
counsel.

     The Company  shall  indemnify  the Trustee and its  officers,  directors,
agents and  employees  against any loss or liability  incurred by it except as
set forth in the next paragraph. The Trustee shall notify the Company promptly
of any claim for which it may seek  indemnity.  The Company  shall  defend the
claim and the Trustee  shall  cooperate in the  defense.  The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of
such  counsel.  The Company need not pay for any  settlement  made without its
consent, which consent shall not be unreasonably withheld.

     The Company need not reimburse any expense or indemnify  against any loss
or liability incurred by the Trustee through negligence or bad faith.

     To secure the Company's payment obligations in this Section,  the Trustee
shall have a lien prior to the  Securities  on all money or  property  held or
collected by the Trustee.

     When the Trustee  incurs  expenses or renders  services after an Event of
Default specified in Section 6.01(f) occurs, the expenses and the compensation
for the services are intended to constitute  expenses of administration  under
any bankruptcy, insolvency or other similar law.

     SECTION 7.08.  REPLACEMENT  OF TRUSTEE.  A resignation  or removal of the
Trustee and  appointment  of a successor  Trustee shall become  effective only
upon the successor  Trustee's  acceptance of  appointment  as provided in this
Section.

     The  Trustee may resign by so  notifying  the  Company.  The Holders of a
majority in principal amount of the then outstanding securities may remove the
Trustee by so notifying the Trustee and the Company in writing. The


                                     C-33

<PAGE>

Company may remove the Trustee if:

     (a) the Trustee fails to comply with Section 7.10;

     (b) the Trustee is adjudged a bankrupt  or an  insolvent  or an order for
   relief is  entered  with  respect  to the  Trustee  under  any  bankruptcy,
   insolvency or other similar law;

     (c) a receiver,  trustee,  liquidator or similar official takes charge of
   the Trustee or its property; or

     (d) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any  reason,  the Company  shall  promptly  appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority  in  principal  amount of the then  outstanding  Securities  may
appoint a successor  Trustee to replace the successor Trustee appointed by the
Company.

     If a  successor  Trustee  does not take  office  within 60 days after the
retiring Trustee resigns or is removed,  the retiring Trustee,  the Company or
the  Holders  of at least  10% in  principal  amount  of the then  outstanding
Securities  may  petition  any  court  of  competent   jurisdiction   for  the
appointment of a successor Trustee.

     If the Trustee fails to comply with Section 7.10, any  Securityholder  or
Beneficial  Holder may petition any court of  competent  jurisdiction  for the
removal of the Trustee and the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the  retiring  Trustee and to the Company.  Thereupon  the  resignation  or
removal of the retiring  Trustee  shall become  effective,  and the  successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture.  The  successor  Trustee  shall mail a notice of its  succession to
Securityholders.  The retiring  Trustee shall  promptly  transfer all property
held by it as Trustee to the successor  Trustee,  subject to the lien provided
for in Section 7.07.  Notwithstanding  the 


                                     C-34

<PAGE>

replacement  of the  Trustee  pursuant to this  Section  7.08,  the  Company's
obligations  under  Section 7.07 hereof shall  continue for the benefit of the
retiring Trustee with respect to expenses and liabilities incurred by it prior
to such replacement.

     SECTION  7.09.   SUCCESSOR  TRUSTEE  BY  MERGER,   ETC.  If  the  Trustee
consolidates,  merges or converts into, or transfers all or substantially  all
of its  corporate  trust  business  to,  another  corporation,  the  successor
corporation without any further act shall be the successor Trustee.

     SECTION 7.10. ELIGIBILITY;  DISQUALIFICATION. This Indenture shall always
have a Trustee  who  satisfies  the  requirements  of TIA ss.  310(a)(1).  The
Trustee shall always have a combined capital and surplus of $50,000,000 as set
forth in its most recent  published  annual report of  condition.  The Trustee
will at all times comply with, and when this Indenture is qualified  under the
TIA will be subject  to, TIA ss.  310(b),  including  the  optional  provision
permitted by the second sentence of TIA ss. 310(b)(9).

     SECTION 7.11.  PREFERENTIAL  COLLECTION OF CLAIMS  AGAINST  COMPANY.  The
Trustee is subject to TIA ss.  311(a),  excluding  anY  creditor  relationship
listed in TIA ss. 311(b).  A Trustee who haS resigned or been removed shall be
subject to TIA ss. 311(a) to thE extent indicated  therein.  In the event that
the  Trustee is also  serving as the Paying  Agent or  Registrar,  the rights,
protections, immunities and indemnities granted to the Trustee hereunder shall
be afforded to the Paying Agent and Registrar.

                            DISCHARGE OF INDENTURE

     SECTION 8.01. TERMINATION OF COMPANY'S OBLIGATIONS.  This Indenture shall
cease to be of further  effect  (except that the Company's  obligations  under
Section  7.07  and  8.03  shall  survive)  when  all  outstanding   Securities
theretofore  authenticated  and issued have been  delivered to the Trustee for
cancelation and the Company has paid all sums payable hereunder.  In addition,
the Company may terminate all of its obligations  under this Indenture (except
the Company's obligations under Sections 7.07 and


                                     C-35

<PAGE>

8.03) if:

     (a) the Securities mature within one year or all of them are to be called
   for  redemption  within one year  under  arrangements  satisfactory  to the
   Trustee for giving the notice of redemption; and

     (b) the Company  irrevocably  deposits in trust with the Trustee money or
   U.S. Government Obligations sufficient to pay principal and interest on the
   Securities  to maturity or  redemption,  as the case may be, and to pay all
   other sums payable by it  hereunder.  The Company may make the deposit only
   during the one- year period and only if Article XI permits it.

However,  the Company's  obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07,
4.01,  7.07,  8.03,  8.04 and in Article X, shall survive until the Securities
are no longer  outstanding.  Thereafter,  only the  Company's  obligations  in
Sections 7.07 and 8.03 shall survive.

     In order to have money  available on a payment  date to pay  principal or
interest on the Securities,  the U.S. Government  Obligations shall be payable
as to  principal or interest on or before such payment date in such amounts as
will provide the necessary money.

     After a deposit  made  pursuant to this  Section  8.01,  the Trustee upon
request  shall   acknowledge   in  writing  the  discharge  of  the  Company's
obligations  under  this  Indenture  except  for those  surviving  obligations
specified above.

     SECTION 8.02. APPLICATION OF TRUST MONEY. The Trustee shall hold in trust
money or U.S.  Government  obligations  deposited  with it pursuant to Section
8.01.  It shall apply the deposited  money and the money from U.S.  Government
Obligations  through the Paying Agent and in accordance with this Indenture to
the payment of principal and interest on the Securities.  Money and securities
so held in trust are not subject to Article XI.

     SECTION  8.03.  REPAYMENT  TO COMPANY.  The Trustee and the Paying  Agent
shall  promptly pay to the Company upon request any excess money or securities
held by them at any time.


                                     C-36

<PAGE>

     The Trustee and the Paying  Agent shall pay to the Company  upon  request
any money held by them for the payment of principal  or interest  that remains
unclaimed  for two years  after the date upon  which such  payment  shall have
become due; PROVIDED, HOWEVER, that the Company shall have first caused notice
of such  payment to the Company to be mailed to each  Securityholder  entitled
thereto  no less than 30 days  prior to such  payment.  After  payment  to the
Company,  Securityholders  entitled  to the money must look to the Company for
payment as general  creditors  unless an  applicable  abandoned  property  law
designates another person. 

     SECTION 8.04. REINSTATEMENT. If (a) the Trustee or Paying Agent is unable
to apply any money in  accordance  with Section 8.02 by reason of any order or
judgment of any court or  governmental  authority  enjoining,  restraining  or
otherwise  prohibiting  such  application  and (b) the  Holders  of at least a
majority in principal amount of the then outstanding  Securities so request by
written notice to the Trustee, the Company's  obligations under this Indenture
and the  Securities  shall be revived and  reinstated as though no deposit had
occurred  pursuant  to Section  8.01 until such time as the  Trustee or Paying
Agent is permitted to apply all such money in  accordance  with Section  8.02;
PROVIDED,  HOWEVER,  that if the  Company  makes any payment of  principal  or
interest of any Security  following the reinstatement of its obligations,  the
Company shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the money held by the Trustee or Paying Agent.


                                  ARTICLE IX

                                  AMENDMENTS

     SECTION 9.01. WITHOUT CONSENT OF HOLDERS. The Company and the Trustee may
amend  this   Indenture  or  the   securities   without  the  consent  of  any
Securityholder:

     (a) to cure any ambiguity, defect or inconsistency; or

     (b) to comply with Sections 5.01 and 10.17; or

     (c) to provide for uncertificated  Securities in addition to certificated
   Securities; or


                                     C-37

<PAGE>

     (d) to make any  change  that does not  materially  adversely  affect the
   legal rights hereunder of any Securityholder; or

     (e) to comply with the TIA;  PROVIDED,  that,  in the case of clauses (a)
   through (d) above,  inclusive,  the Company has delivered to the Trustee an
   Opinion of Counsel  stating that such change does not adversely  affect the
   rights of any Securityholder.

     SECTION  9.02.  WITH  CONSENT OF HOLDERS.  Subject to Section  6.07,  the
Company and the Trustee may amend this  Indenture or the  Securities  with the
written  consent of the Holders of at least a majority in principal  amount of
the then  outstanding  Securities.  Subject  to  Sections  6.04 and 6.07,  the
Holders of a majority in principal amount of the then  outstanding  Securities
may also waive  compliance  in a  particular  instance by the Company with any
provision of this Indenture or the Securities. However, without the consent of
each  Securityholder  affected,  an amendment or waiver under this Section may
not:

     (a) reduce the amount of  Securities  whose  Holders  must  consent to an
   amendment or waiver;

     (b) reduce the rate of or change the time for  payment of interest on any
   Security;

     (c) reduce the principal of or change the fixed  maturity of any Security
   or alter the redemption provisions with respect thereto;

     (d) make any  Security  payable in money  other  than that  stated in the
   Security;

     (e) make any change in Section 6.04, 6.07 or 9.02 which adversely affects
   the rights of the Securityholders;

     (f) make any change  that  adversely  affects  the right to  convert  any
   Security;

     (g) make any change in Article XI that  adversely  affects  the rights of
   any Securityholder; or


                                     C-38

<PAGE>

     (h) waive a default in the payment of the principal (except principal due
   by reason of acceleration)  of, or interest on, any Security or any Default
   which  materially and adversely  affects the rights of any  Securityholders
   under Article X.

     After an amendment or waiver under this Section  becomes  effective,  the
Company  shall  mail  to  Securityholders  a  notice  briefly  describing  the
amendment or waiver.

     SECTION 9.03.  COMPLIANCE  WITH TRUST  INDENTURE ACT. Every  amendment to
this  Indenture  or the  Securities  shall  be  set  forth  in a  supplemental
indenture that complies with the TIA as then in effect.

     SECTION 9.04.  REVOCATION  AND EFFECT OF CONSENTS.  Until an amendment or
waiver  becomes  effective,  a consent  to it by a Holder of a  Security  is a
continuing  consent by the Holder and every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting  Holder's
Security,  even if  notation  of the  consent  is not  made  on any  Security.
However, any such Holder or subsequent Holder may revoke the consent as to his
Security  or portion  of a  Security  if the  Trustee  receives  the notice of
revocation  before  the  date on  which  the  Trustee  receives  an  Officer's
Certificate  certifying that the Holders of the requisite  principal amount of
securities have consented to the amendment or waiver.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of  determining  the Holders  entitled to consent to any  amendment or
waiver. If a record date is fixed, then  notwithstanding the provisions of the
immediately preceding paragraph, those persons who were Holders at such record
date (or their duly  designated  proxies),  and only those  persons,  shall be
entitled  to consent  to such  amendment  or waiver or to revoke  any  consent
previously  given,  whether or not such persons  continue to be Holders  after
such record date. No consent shall be valid or effective for more than 90 days
after such record date unless consents from Holders of the principal amount of
securities  required  hereunder  for such  amendment or waiver to be effective
shall have also been given and not revoked within such 90-day period.


                                     C-39

<PAGE>

     After an  amendment  or waiver  becomes  effective  it shall  bind  every
Securityholder,  unless  it is of the type  described  in any of  clauses  (a)
through (h) of Section 9.02. In such case,  the amendment or waiver shall bind
each Holder of a Security who has consented to it and every subsequent  Holder
of a  Security  that  evidences  the  same  debt  as the  consenting  Holder's
Security.

     SECTION  9.05.  NOTATION ON OR EXCHANGE  OF  SECURITIES.  The Trustee may
place an  appropriate  notation  about an  amendment or waiver on any Security
thereafter authenticated. The Company in exchange for all Securities may issue
and the Trustee shall  authenticate  new Securities that reflect the amendment
or waiver.

     SECTION 9.06. TRUSTEE PROTECTED.  The Trustee shall sign all supplemental
indentures,  except that the Trustee need not sign any supplemental  indenture
that adversely affects its rights.


                                   ARTICLE X

                                  CONVERSION

     SECTION 10.01.  CONVERSION PRIVILEGE.  A Holder of a Security may convert
it into Common  Stock at any time during the period  stated in  paragraph 9 of
the Securities. The number of shares issuable upon conversion of a Security is
determined  as follows:  divide the  principal  amount to be  converted by the
conversion  price in effect on the  Conversion  Date.  Round the result to the
nearest 1/100th of a share.

     The initial  conversion price is stated in paragraph 9 of the Securities.
The conversion price is subject to adjustment.

     A Holder may  convert a portion of a Security if the portion is $1,000 or
an integral  multiple of $1,000.  Provisions of this  Indenture  that apply to
conversion of all of a Security also apply to conversion of a portion of it.

     SECTION 10.02. CONVERSION PROCEDURE. To convert a Security, a Holder must
satisfy  the  requirements  in  paragraph  9 of the  Securities.  As  soon  as
practical,   the


                                     C-40

<PAGE>

Company  shall deliver  through the  Conversion  Agent a  certificate  for the
number of full shares of Common Stock  issuable upon the  conversion  together
with  payment in lieu of any  fractional  share.  The person in whose name the
certificate  is registered  shall be treated as a stockholder of record on and
after the Conversion Date.

     No payment or  adjustment  will be made on conversion of any Security for
interest  accrued  thereon or  dividends  on any Common  Stock  issued and the
Holder  will  lose  any  right  to  payment  of  interest  on  the  Securities
surrendered for conversion; PROVIDED, HOWEVER, that upon a call for redemption
by the Company,  accrued and unpaid  interest to the Redemption  Date shall be
payable  with  respect to  Securities  that are  converted  after a redemption
notice  has  been  mailed  pursuant  to  Section  3.03  and on or prior to the
Redemption Date. Securities  surrendered for conversion during the period from
the regular record date for an interest payment to the corresponding  interest
payment  date (except  Securities  called for  redemption  as described in the
preceding  sentence)  must be accompanied by payment of an amount equal to the
interest thereon which the Holder is to receive on such interest payment date.

     If a Holder  converts more than one Security at the same time, the number
of full  shares  issuable  upon the  conversion  shall  be based on the  total
principal amount of the Securities surrendered.

     Upon a surrender of a Definitive  Security that is converted in part, the
Company  shall issue and the Trustee shall  authenticate  for the Holder a new
Definitive  Security equal in principal  amount to the unconverted  portion of
the Security surrendered.

     If the last day on which a Security may be  converted is a Legal  Holiday
in a  place  where  a  Conversion  Agent  is  located,  the  Security  may  be
surrendered to that Conversion  Agent on the next succeeding day that is not a
Legal Holiday.

     Upon conversion of an interest in the Global Security, the Trustee or the
Securities Custodian,  at the direction of the Trustee,  shall make a notation
on  such  Global  Security  as  to  the  reduction  in  the  principal  amount
represented thereby.


                                     C-41

<PAGE>

     SECTION 10.03. FRACTIONAL SHARES. The Company will not issue a fractional
share of Common Stock upon conversion of a Security.  Instead the Company will
deliver payment in lieu thereof for the current market value of the fractional
share.  The current  market  value of a fraction of a share is  determined  as
follows:  multiply the Current  Market Price of a full share by the  fraction.
Round the result to the nearest cent.

     SECTION  10.04.  TAXES ON  CONVERSION.  The Company  will pay any and all
taxes that may be payable  in  respect of the issue or  delivery  of shares of
Common Stock on conversion of Securities  pursuant  hereto.  The Company shall
not,  however,  be  required to pay any tax which may be payable in respect of
any transfer involved in the issue and delivery of shares of Common Stock in a
name  other  than  that of the  Holder of the  Security  or  Securities  to be
converted,  and no such issue or  delivery  shall be made unless and until the
person  requesting  such issue has paid to the  Company the amount of any such
tax, or has  established to the  satisfaction of the Company that such tax has
been paid.

     SECTION  10.05.  COMPANY TO PROVIDE  STOCK.  The Company has reserved and
shall continue to reserve out of its  authorized but unissued  Common Stock or
its Common Stock held in treasury  enough shares of Common Stock to permit the
conversion of the Securities in full.

     All shares of Common  Stock  which may be issued upon  conversion  of the
Securities shall be fully paid and non assessable.

     The Company will comply with all securities laws regulating the offer and
delivery of shares of Common Stock upon  conversion of Securities and will use
its best efforts to list such shares on each national  securities  exchange on
which the Common Stock is listed.

     SECTION  10.06.  ADJUSTMENT  FOR  DIVIDENDS AND  DISTRIBUTIONS  OF COMMON
STOCK. In case the Company shall pay or make a dividend or other  distribution
on any class of Capital Stock of the Company in Common Stock,  the  conversion
price in effect at the opening of business on the day following the date fixed
for the  determination  of  stockholders  entitled to receive such dividend or
other 


                                     C-42

<PAGE>

distribution  shall be  reduced  by  multiplying  such  conversion  price by a
fraction of which the numerator  shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such  determination
and the denominator  shall be the sum of such number of shares of Common Stock
and the total number of shares of Common Stock  constituting  such dividend or
other distribution,  such reduction to become effective  immediately after the
opening  of   business  on  the  day   following   the  date  fixed  for  such
determination. For the purposes of this Section 10.06, the number of shares of
Common  Stock at any time  outstanding  shall not  include  shares held in the
treasury of the Company but shall include shares  issuable in respect of scrip
certificates  issued in lieu of  fractions  of shares  of  Common  Stock.  The
Company will not pay any dividend or make any distribution on shares of Common
Stock held in the treasury of the Company.

     SECTION  10.07.  ADJUSTMENT  FOR RIGHTS ISSUE.  In case the Company shall
issue rights or warrants to all holders of its Common Stock  entitling them to
subscribe  for or  purchase  shares of Common  Stock at a price per share less
than the Current  Market Price per share of the Common Stock on the date fixed
for the  determination  of  stockholders  entitled  to receive  such rights or
warrants, the conversion price in effect at the opening of business on the day
following  the  date  fixed  for  such  determination   shall  be  reduced  by
multiplying  such conversion  price by a fraction of which the numerator shall
be the number of shares of Common Stock  outstanding  at the close of business
on the date fixed for such  determination  plus the number of shares of Common
Stock which the aggregate of the offering  price of the total number of shares
of Common Stock so offered for subscription or purchase would purchase at such
Current  Market  Price and the  denominator  shall be the  number of shares of
Common Stock  outstanding  at the close of business on the date fixed for such
determination  plus the  number  of  shares of  Common  Stock so  offered  for
subscription or purchase, such reduction to become effective immediately after
the  opening  of  business  on the day  following  the  date  fixed  for  such
determination. For the purposes of this Section 10.07, the number of shares of
Common  Stock at any time  outstanding  shall not  include  shares held in the
treasury of the Company but shall include shares  issuable in respect of scrip
certificates  issued in lieu of  fractions  of shares  of  Common  Stock.  The
Company  will not issue any 


                                     C-44

<PAGE>

rights or warrants in respect of shares of Common  Stock held in the  treasury
of the Company.

     SECTION 10.08.  ADJUSTMENT FOR OTHER  DISTRIBUTIONS.  In case the Company
shall, by dividend or otherwise, distribute to all holders of its Common Stock
evidences of its indebtedness or assets (including  securities,  but excluding
any  rights  or  warrants  referred  to in  Section  10.07,  any  dividend  or
distribution  paid in cash out of the earned  surplus of the  Company  and any
dividend or distribution  referred to in Section 10.06),  the conversion price
shall be  adjusted  so that the same  shall  equal  the  price  determined  by
multiplying the conversion price in effect  immediately  prior to the close of
business on the date fixed for the  determination of stockholders  entitled to
receive such  distribution  by a fraction of which the numerator  shall be the
Current  Market Price per share of the Common Stock on the date fixed for such
determination  less the then fair market value (as  determined by the Board of
Directors,  whose  determination  shall be conclusive and contained in a Board
Resolution  filed with the  Trustee) of the portion of the assets or evidences
of indebtedness so distributed applicable to one share of Common Stock and the
denominator  shall be such Current Market Price per share of the Common Stock,
such  adjustment  to become  effective  immediately  prior to the  opening  of
business  on the  day  following  the  date  fixed  for the  determination  of
stockholders entitled to receive such distribution.

     SECTION  10.09.  ADJUSTMENT  FOR  SUBDIVISION  OF COMMON  Stock.  In case
outstanding  shares of Common Stock shall be subdivided  into a greater number
of shares of Common Stock,  the  conversion  price in effect at the opening of
business  on the day  following  the day upon which such  subdivision  becomes
effective  shall  be  proportionately   reduced,  and,  conversely,   in  case
outstanding  shares of Common  Stock  shall  each be  combined  into a smaller
number  of  shares  of Common  Stock,  the  conversion  price in effect at the
opening of business on the day following  the day upon which such  combination
becomes  effective  shall be  proportionately  increased,  such  reduction  or
increase,  as the case may be,  to  become  effective  immediately  after  the
opening of business on the day following  the day upon which such  subdivision
or combination becomes effective.

     SECTION  10.10.  ADJUSTMENT  FOR  RECLASSIFICATION  OF


                                     C-44

<PAGE>

COMMON STOCK. The  reclassification of Common Stock into securities  including
other than Common Stock shall be deemed to involve (a) a distribution  of such
securities  other than Common  Stock to all  holders of Common  Stock (and the
effective date of such reclassification  shall be deemed to be "the date fixed
for the determination of stockholders  entitled to receive such  distribution"
and "the date  fixed for such  determination"  within  the  meaning of Section
10.08) and (b) a subdivision or combination, as the case may be, of the number
of  shares   of   Common   Stock   outstanding   immediately   prior  to  such
reclassification  into the  number  of  shares  of  Common  Stock  outstanding
immediately  thereafter (and the effective date of such reclassification shall
be deemed to be "the day upon which such  subdivision  becomes  effective"  or
"the day upon which such combination becomes  effective",  as the case may be,
and "the day upon which such  subdivision  or combination  becomes  effective"
within the meaning of Section 10.09.

     SECTION 10.11. [Intentionally Omitted]

     SECTION  10.12.  WHEN  ADJUSTMENT  MAY BE DEFERRED.  No adjustment in the
conversion price need be made for a transaction referred to in Sections 10.06,
10.07,  10.08,  10.09 or 10.10 unless the adjustment would require an increase
or decrease of at least 1% in the conversion  price.  Any adjustments that are
not made shall be carried  forward  and taken into  account in any  subsequent
adjustment.

     All calculations  under this Article shall be made to the nearest cent or
to the nearest 1/100th of a share, as the case may be.

     SECTION 10.13.  WHEN NO ADJUSTMENT  REQUIRED.  No adjustment need be made
for a transaction  referred to in Sections 10.06, 10.07, 10.08, 10.09 or 10.10
if all  Securityholders  are entitled to participate  in the  transaction on a
basis and with notice that the Board of  Directors  determines  to be fair and
appropriate  in light of the basis and notice on which holders of Common Stock
participate in the transaction.

     No  adjustment  need be made  for  rights  to  purchase  Common  Stock or
issuance  of Common  Stock  pursuant  to a Company  plan for  reinvestment  of
dividends or interest.


                                     C-45

<PAGE>

     No adjustment  need be made for a change in the par value or no par value
of the Common Stock.

     To the extent the Securities become  convertible into cash, no adjustment
need be made thereafter as to the cash. Interest will not accrue on the cash.

     SECTION  10.14.  NOTICE OF ADJUSTMENT.  Whenever the conversion  price is
adjusted, the Company shall promptly mail to Securityholders and the Trustee a
notice  of  the  adjustment.  The  Company  shall  file  with  the  Trustee  a
certificate from the Company's  independent public accountants briefly stating
the facts  requiring  the  adjustment  and the  manner of  computing  it.  The
certificate shall be conclusive evidence that the adjustment is correct.

     SECTION  10.15.  VOLUNTARY  REDUCTION.  The Company from time to time may
reduce the conversion price by any amount for any period of time if the period
is at least 20 days or such longer period as may be required by law and if the
reduction is irrevocable during the period, provided, that in no event may the
conversion price be less than the par value of a share of Common Stock.

     Whenever  the  conversion  price is reduced,  the  Company  shall mail to
Securityholders and the Trustee a notice of the reduction and comply with Rule
13e-4  promulgated  by the  SEC  under  the  Exchange  Act,  if  such  rule is
applicable  and any other  applicable  rules and  regulations  of the SEC. The
notice shall state the reduced  conversion  price and the period it will be in
effect.

     A  reduction  of the  conversion  price  does not  change or  adjust  the
conversion  price otherwise in effect for purposes of Sections  10.06,  10.07,
10.08, 10.09 and 10.10.

     SECTION 10.16. NOTICE OF CERTAIN TRANSACTIONS.

If:

     (a) the Company  takes any action that would require an adjustment in the
   conversion price pursuant to Sections 10.06,  10.07,  10.08, 10.09 or 10.10
   and if the Company  does not let  Securityholders  participate  pursuant to
   Section 10.13;


                                     C-46

<PAGE>

     (b) the  Company  takes any  action  that  would  require a  supplemental
   indenture pursuant to Section 10.17; or

     (c) there is a liquidation or dissolution of the Company,

the Company shall mail to Securityholders and the Trustee a notice stating the
proposed record date for a dividend or distribution or the proposed  effective
date of a subdivision, combination,  reclassification,  consolidation, merger,
transfer,  lease,  liquidation  or  dissolution.  The Company  shall mail such
notice at least 15 days before  such date.  Failure to mail such notice or any
defect in it shall not affect the validity of the transaction.

     SECTION 10.17.  REORGANIZATION OF COMPANY. If the Company is a party to a
transaction subject to Section 5.01, or a merger which reclassifies or changes
its  outstanding  Common Stock,  upon  consummation  of such  transaction  the
Securities shall automatically  become convertible into the kind and amount of
securities,  cash or other  assets  which the Holder of a Security  would have
owned immediately after the  consolidation,  merger,  transfer or lease if the
Holder  had  converted  the  Security  at  the  conversion   price  in  effect
immediately  before the effective date of the transaction.  Concurrently  with
the consummation of such transaction, the person obligated to issue securities
or deliver cash or other assets upon conversion of the Securities  shall enter
into  a  supplemental   indenture  so  providing  and  further  providing  for
adjustments  which shall be as nearly  equivalent  as may be  practical to the
adjustments  provided for in this Article. The successor Company shall mail to
Securityholders a notice describing the supplemental indenture.

     If securities deliverable upon conversion of the securities,  as provided
above,  are themselves  convertible into the securities of an Affiliate of the
formed, surviving, transferee or lessee corporation, that issuer shall join in
the supplemental indenture which shall so provide.

     If this Section applies, Section 10.06 does not apply.


                                     C-47

<PAGE>

     SECTION 10.18.  COMPANY  DETERMINATION  FINAL. Any determination that the
Company or the Board of Directors must make pursuant to Section 10.03,  10.08,
or 10.13 is conclusive.

     SECTION 10.19. TRUSTEE'S DISCLAIMER. The Trustee has no duty to determine
when an adjustment under this Article should be made, how it should be made or
what it should be. The Trustee has no duty to determine whether any provisions
of a supplemental indenture under Section 10.17 are correct. The Trustee makes
no  representation  as to the  validity or value of any  securities  or assets
issued upon conversion of the Securities. The Trustee shall not be responsible
for the Company's  failure to comply with this Article.  Each Conversion Agent
other than the Company  shall have the same  protection  under this Section as
the Trustee.


                                  ARTICLE XI

                          SUBORDINATION OF SECURITIES

     SECTION 11.01.  SECURITIES  SUBORDINATE TO SENIOR Debt. The Company,  for
itself,  its successors and assigns,  covenants and agrees, and each Holder of
the Securities,  by his acceptance  thereof likewise covenants and agrees that
all Securities  issued  hereunder  shall be subordinated  and subject,  to the
extent  and in the manner  herein set forth,  in right of payment to the prior
payment in full of all Senior  Debt and will not be superior in payment to the
Company's (a) 6% Convertible  Subordinated  Debentures Due 2002 and (b) 6-3/8%
Convertible Subordinated Debentures Due 2004.

     SECTION 11.02.  NO PAYMENTS WHEN SENIOR DEBT IN DEFAULT;  PAYMENT OVER OF
PROCEEDS UPON DISSOLUTION,  ETC. In the event the Company shall default in the
payment on any Senior Debt when the same becomes due and  payable,  whether at
maturity or at a date fixed for  prepayment  or by  declaration  or otherwise,
then,  unless and until such default  shall have been cured or waived or shall
have  ceased to  exist,  no direct or  indirect  payment  (in cash,  property,
securities,  by  setoff  or  otherwise)  shall be made or agreed to be made on
account of the  principal of or interest on the  Securities,  or in respect of
any redemption,  retirement, purchase or other acquisition (except through the
conversion


                                     C-48

<PAGE>

thereof) of any of the Securities.

     Upon the  happening  of an event of  default  with  respect to any Senior
Debt,  as  defined  therein  or in the  instrument  under  which  the  same is
outstanding, permitting the holders thereof to accelerate the maturity thereof
(under  circumstances  when  the  terms  of the  preceding  paragraph  are not
applicable),  unless and until such event of default  shall have been cured or
waived or shall have ceased to exist, no direct or indirect  payment (in cash,
property,  securities,  by setoff or otherwise)  shall be made or agreed to be
made on account of the  principal  of or  interest  on the  Securities,  or in
respect of any redemption,  retirement,  purchase or other acquisition (except
through the conversion thereof) of any of the Securities.

     In the event of:

     (a)    any    insolvency,    bankruptcy,    receivership,    liquidation,
   reorganization,  readjustment,  composition  or  other  similar  proceeding
   relating  to  the  Company  or  its  property,  or  any  of  the  Company's
   subsidiaries that are guarantors under Designated Senior Debt,

     (b) any proceeding for the  liquidation,  dissolution or other winding-up
   of the Company or its property or any of the  Company's  subsidiaries  that
   are guarantors  under the amended and restated loan  agreement  dated as of
   June 17,  1993  with a  syndicate  of  banks  led by NM  Rothschild  & Sons
   Limited,  as the same  may be  amended  from  time to  time,  voluntary  or
   involuntary, whether or not involving insolvency or bankruptcy proceedings,

     (c) any assignment by the Company for the benefit of creditors, or

     (d) any other marshalling of the assets of the Company,

all  Senior  Debt   (including  any  interest   thereon   accruing  after  the
commencement of any such  proceedings)  shall first be paid in full before any
payment or  distribution  (direct or indirect),  whether in cash,  property or
securities, by setoff or otherwise,  shall be made to any Holder on account of
any Securities, and to that end any payment or


                                     C-49

<PAGE>

distribution,  whether in cash,  property or securities (other than securities
of  the  Company  or  any  other  corporation   provided  for  by  a  plan  of
reorganization  or readjustment the payment of which is subordinate,  at least
to the extent provided in this Article with respect to the Securities,  to the
payment  of all  Senior  Debt at the time  outstanding  and to any  securities
issued  in  respect  thereof  under  any  such  plan  of   reorganization   or
readjustment)  which would  otherwise  (but for the  subordination  provisions
contained  in this  Article)  be  payable  or  deliverable  in  respect of the
Securities shall be paid or delivered  directly to the holders of Senior Debt,
as their respective interests may appear, until all Senior Debt (including any
interest  thereon  accruing after the  commencement  of any such  proceedings)
shall have been paid in full.

     If the  Securities  are  declared  due and payable  before  their  stated
maturity because of the occurrence of an Event of Default (under circumstances
where the  preceding  paragraph  is not  applicable),  no  payment  (direct or
indirect)  shall be made in  respect  of any  securities  unless and until all
Senior  Debt has been  paid in full or such  declaration  and its  consequence
shall have been  rescinded and all such  defaults  shall have been remedied or
waived.

     If any payment or  distribution  (other than securities of the Company or
any other corporation provided for by a plan of reorganization or readjustment
the payment of which is  subordinate,  at least to the extent provided in this
Article with respect to the  Securities,  to the payment of all Senior Debt at
the time outstanding and to any securities issued in respect thereof under any
such plan of reorganization or readjustment)  shall be received by the Trustee
or the Holders in contravention of any of the terms of this Article and before
all the Senior Debt has been paid in full, such payment or distribution  shall
be held in trust for the benefit of, and shall be paid over or  delivered  and
transferred  to, the holders of such Senior  Debt at the time  outstanding  as
their respective interests may appear for application to the payment of Senior
Debt until all Senior Debt (including any interest  thereon accruing after the
commencement of any such proceeding  referred to in paragraph (a), (b), (c) or
(d) above)  shall have been paid in full.  If the  Trustee or any such  Holder
fails to endorse or assign any such  payment or  distribution  as  required by
this Section, the Trustee and the Holder of each Security by his


                                     C-50

<PAGE>

acceptance  thereof  authorizes each holder of Senior Debt, any representative
or representatives of holders of Senior Debt and the trustee or trustees under
any indenture pursuant to which any instrument evidencing such Senior Debt may
have been issued to so endorse or assign the same.

     No holder of Senior  Debt  shall be  prejudiced  in the right to  enforce
subordination  of the  Securities  by any act or failure to act on the part of
the Company.

     Subject to the payment in full of all Senior Debt,  the Holders  shall be
subrogated  (equally and ratably with the holders of all  indebtedness  of the
Company  which ranks on a parity with the  Securities  and is entitled to like
rights of  subrogation) to the rights of the holders of Senior Debt to receive
payments or  distributions  applicable to the Senior Debt until the Securities
shall be paid in full, and no such payments or distributions shall, as between
the Company,  its  creditors  other than the holders of Senior  Debt,  and the
Holders of the  Securities,  be deemed to be a payment by the Company to or on
account of the Securities. The provisions of this Article are and are intended
solely for the purposes of defining the relative  rights of the Holders of the
Securities,  on the one hand,  and the  holders of Senior  Debt,  on the other
hand, and nothing  contained in this Article or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as between the Company,  its
creditors  other  than the  holders  of  Senior  Debt and the  Holders  of the
Securities,  the obligation of the Company to pay the Holders the principal of
and  interest  on the  Securities  as and when the same  shall  become due and
payable in accordance  with the terms  thereof,  or prevent the Trustee or the
Holders from exercising all rights, powers and remedies otherwise permitted by
applicable  law or under  this  Indenture,  upon a default or Event of Default
hereunder,  all  subject  to the rights of the  holders of the Senior  Debt to
receive cash,  property or securities  otherwise payable or deliverable to the
Trustee or the Holders.

     Upon any payment or  distribution  pursuant to this Section,  the Trustee
shall be  entitled  to rely upon any  order or decree of a court of  competent
jurisdiction  in which  any  proceedings  of the  nature  referred  to in this
Section, are pending, and the Trustee,  subject as between the Trustee and the
Holders to the  provisions of


                                     C-51

<PAGE>

Section 7.01,  shall be entitled to rely upon a certificate of the liquidating
trustee or agent or other person  making such payment or  distribution  to the
Trustee or to the Holders for the purpose of ascertaining the persons entitled
to participate in such payment or distribution, the holders of the Senior Debt
and other indebtedness of the Company,  the amount thereof or payable thereon,
the  amount  or  amounts  paid or  distributed  thereon  and all  other  facts
pertinent  thereto  or  to  this  Section.  In  the  event  that  the  Trustee
determines, in good faith, that evidence is required with respect to the right
of any  person as a holder of Senior  Debt to  participate  in any  payment or
distribution  pursuant to this Section, the Trustee may request such person to
furnish  evidence  to the  reasonable  satisfaction  of the  Trustee as to the
amount of Senior  Debt held by such  person,  as to the  extent to which  such
person is entitled to participate in such payment or  distribution,  and as to
other facts pertinent to the rights of such person under this Section,  and if
such  evidence  is not  furnished,  the  Trustee may defer any payment to such
person  pending  judicial  determination  as to the  right of such  person  to
receive such payment.

     SECTION 11.03.  TRUSTEE TO EFFECTUATE  SUBORDINATION.  The Holder of each
Security by his acceptance  thereof  authorizes and directs the Trustee in his
behalf to take such action as may be necessary or  appropriate  to acknowledge
or effectuate the  subordination  as provided in this Article and appoints the
Trustee as attorney-in-fact for any and all such purposes.

     SECTION  11.04.  TRUSTEE  NOT  CHARGED  WITH  KNOWLEDGE  OF  PROHIBITION.
Notwithstanding  the provisions of this Article or any other provision of this
Indenture,  but  subject  as  between  the  Trustee  and  the  Holders  to the
provisions of Section 7.01, the Trustee shall not be charged with knowledge of
the  existence  of any Senior  Debt,  or of any  default in the payment of any
Senior Debt, or of any facts which would prohibit the making of any payment of
moneys to or by the Trustee,  unless and until three  business  days after the
Trustee shall have  received  written  notice  thereof from the Company or any
holder of Senior Debt or the representative or representatives of such holder;
nor shall the  Trustee be  charged  with  knowledge  of the curing of any such
default or of the  elimination  of the


                                     C-52

<PAGE>

act or  condition  preventing  any such  payment  unless and until the Trustee
shall have received an Officers' Certificate to such effect. The provisions of
this  Section  shall not limit any rights of holders of Senior Debt under this
Article XI to recover from the Holders of  Securities  any payment made to any
such Holder.

     SECTION  11.05.  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR Debt.  The Trustee
shall be entitled to all the rights set forth in this  Article with respect to
any Senior Debt which may at any time be held by it, to the same extent as any
other holder of Senior Debt, and nothing in Section 7.11, or elsewhere in this
Indenture, shall deprive the Trustee of any of its rights as such holder.

     SECTION 11.06.  ARTICLE  APPLICABLE TO PAYING AGENT.  In case at any time
any Paying  Agent  other than the  Trustee  shall have been  appointed  by the
Company  and be then  acting  hereunder,  the term  "Trustee"  as used in this
Article  shall in such case (unless the context  shall  otherwise  require) be
construed as extending to and  including  such Paying Agent within its meaning
as fully for all  intents and  purposes as if such Paying  Agent were named in
this  Article in addition to or in place of the  Trustee;  PROVIDED,  however,
that Sections  11.04 and 11.05 shall not apply to the Company or any Affiliate
of the Company if the Company or such Affiliate acts as Paying Agent.


                                  ARTICLE XII

                          RIGHT TO REQUIRE REPURCHASE

     SECTION 12.01. RIGHT TO REQUIRE REPURCHASE. In the event that there shall
occur a Designated Event with respect to the Company, then each Securityholder
shall have the right,  at such  Securityholder's  option,  but  subject to the
provisions  of  Article XI and this  Article  XII to  require  the  Company to
purchase,  and upon exercise of such right the Company shall purchase,  all or
any part of such Securityholder's  Securities in principal amount of $1,000 or
an integral  multiple thereof on the date (the  "Repurchase  Date") that is 45
days after the date of the Company  Notice,  at 100% of the principal  amount,
together with accrued interest to the Repurchase Date.


                                     C-53

<PAGE>

     SECTION 12.02. NOTICE;  METHOD OF EXERCISING  REPURCHASE RIGHT. (a) On or
before the 30th day after the occurrence of a Designated  Event,  the Company,
or at the  request of the  Company,  the  Trustee,  shall  give  notice of the
occurrence  of the  Designated  Event  and of the  repurchase  right set forth
herein arising as a result thereof (the "Company Notice") by first-class mail,
postage pre-paid,  to each Holder and each Beneficial Holder of the Securities
at such Holder's or Beneficial  Holder's  address  appearing in the Securities
Register or  Participants  List. The Company shall also deliver a copy of such
Company  Notice to the Trustee and cause a copy of such  Company  Notice to be
published in a newspaper of general  circulation  in the Borough of Manhattan,
The City of New York.

     Each Company Notice shall state:

     (i) the Repurchase Date,

     (ii) the date by which the repurchase right must be exercised,

     (iii) the price at which the  repurchase is to be made, if the repurchase
    right is exercised, and

     (iv) a description of the procedure which a Securityholder must follow to
    exercise a repurchase right.

     No failure of the Company to give the  foregoing  notice  shall limit any
Securityholder's right to exercise a repurchase right.

     (b) To exercise a repurchase right, a Securityholder shall deliver to the
   Company (or an agent  designated  by the  Company  for such  purpose in the
   Company  Notice),  on or before the 30th day after the date of the  Company
   Notice, (i) written notice of the Securityholder's  exercise of such right,
   which notice shall set forth the name of the Securityholder,  the principal
   amount of the  Security or  Securities  (or  portion of a  Security)  to be
   repurchased,  and a statement  that an election to exercise the  repurchase
   right is being made  thereby,  and (ii) the  Security  or  Securities  with
   respect to which the repurchase right is being exercised, duly endorsed for
   transfer to the Company. Such written notice shall be irrevocable. If the


                                     C-54

<PAGE>

   Repurchase  Date falls  between any record date for the payment of interest
   on the Securities and the next succeeding interest payment date, Securities
   to be repurchased  must be accompanied by payment of an amount equal to the
   interest thereon which the registered  Holder thereof is to receive on such
   interest payment date.

     (c) In the event a repurchase right shall be exercised in accordance with
   the  terms  hereof,  the  Company  shall  pay or cause to be paid the price
   payable  with  respect  to the  Security  or  Securities  as to  which  the
   repurchase  right has been exercised in cash to the  Securityholder  on the
   Repurchase  Date.  In the event that a repurchase  right is exercised  with
   respect to less than the entire principal amount of a surrendered Security,
   the Company  shall execute and deliver to the Trustee and the Trustee shall
   authenticate  for issuance in the name of the  Securityholder a replacement
   Security  or  Securities  in  the   aggregate   principal   amount  of  the
   unrepurchased portion of such surrendered Security.

     SECTION 12.03.  CERTAIN  DEFINITIONS.  For purposes of Sections 12.01 and
12.02:

     (a) A "Designated  Event" shall be deemed to have occurred on the date of
   consummation of the purchase,  merger or other  acquisition  transaction as
   referred to in the definition of a Change in Control.

     (b) As used herein,  a "Change in Control" of the Company shall be deemed
   to have occurred when (i) all or substantially  all of the Company's assets
   are sold as an  entirety to any person or related  group of  persons;  (ii)
   there shall be consummated any  consolidation  or merger of the Company (A)
   in which the Company is not the continuing or surviving  corporation (other
   than a  consolidation  or  merger  with a wholly  owned  subsidiary  of the
   Company in which all shares of Common Stock  outstanding  immediately prior
   to the  effectiveness  thereof are changed into or  exchanged  for the same
   consideration) or (B) pursuant to which the Common Stock would be converted
   into  cash,  securities  or other  property,  in each  case,  other  than a
   consolidation  or merger of the  Company in which the holders of the Common
   Stock immediately  prior to the  consolidation or merger have,  directly or
   indirectly,


                                     C-55

<PAGE>

   at least a majority  of the common  stock of the  continuing  or  surviving
   corporation  immediately  after such  consolidation or merger, or (iii) any
   person, or any persons acting together which would constitute a "group" for
   purposes of Section 13(d) of the Exchange Act (other than the Company,  any
   subsidiary,  any employee stock  purchase plan,  stock option plan or other
   stock  incentive  plan or program,  retirement  plan or automatic  dividend
   reinvestment plan or any  substantially  similar plan of the Company or any
   subsidiary or any person holding  securities of the Company for or pursuant
   to the  terms  of any  such  employee  benefit  plan),  together  with  any
   Affiliates thereof,  shall beneficially own (as defined in Rule 13d-3 under
   the Exchange  Act) at least 50% of the total voting power of all classes of
   Capital Stock of the Company  entitled to vote generally in the election of
   directors of the Company.

     (c) Notwithstanding paragraph (b) above, a Change in Control shall not be
   deemed to have occurred if (i) the Current Market Price of the Common Stock
   is at least  equal to 105% of the  conversion  price of the  Securities  in
   effect  immediately  preceding the time of such Change in Control,  or (ii)
   all of the consideration (excluding cash payments for fractional shares) in
   the  transaction  giving  rise to such  Change in Control to the holders of
   Common Stock  consists of shares of common  stock that are, or  immediately
   upon issuance will be, listed on a national  securities  exchange or quoted
   in the NASDAQ National Market System,  and as a result of such  transaction
   the Securities become  convertible  solely into such common stock, or (iii)
   the consideration in the transaction  giving rise to such Change in Control
   to the holders of Common Stock  consists of cash,  securities  that are, or
   immediately upon issuance will be, listed on a national securities exchange
   or quoted in the NASDAQ  National  Market System,  or a combination of cash
   and  such  securities,   and  the  aggregate  fair  market  value  of  such
   consideration (which, in the case of such securities, shall be equal to the
   average  of the daily  closing  prices of such  securities  during  the ten
   consecutive  trading days  commencing  with the sixth trading day following
   consummation of such  transaction) is at least 105% of the conversion price
   of the Securities in


                                     C-56

<PAGE>

   effect  on  the  date  immediately  preceding  the  closing  date  of  such
   transaction.

     SECTION  12.04.  COMPLIANCE  WITH  RULE  13E-4.  In  connection  with any
repurchase of Securities pursuant to this Article XII, the Company will comply
with Rule 13e-4 promulgated by the SEC under the Exchange Act, if such Rule is
applicable, and any other applicable rules and regulations of the SEC.

Ladies and Gentlemen:


     SECTION 1. INTRODUCTORY.  The Coeur d'Alene Mines  Corporation,  an Idaho
corporation  (the  "Company"),   proposes  to  issue  and  sell  to  you  (the
"Purchaser") an aggregate of $125,000,000 aggregate principal amount of 7 1/4%
Convertible  Subordinated  Debentures due 2005 (the "Firm  Debentures")  to be
issued  under an  indenture  dated as of October 14,  1997 (the  "Indenture"),
between the Company and Bankers Trust Company, as trustee (the "Trustee"). The
Company also proposes to sell to the Purchaser,  upon the terms and conditions
set forth in  Section  3 hereof,  up to an  additional  $18,750,000  aggregate
principal  amount of its 7 1/4% Convertible  Subordinated  Debentures due 2005
(the "Optional  Debentures").  The Firm Debentures and the Optional Debentures
are  convertible  into  shares of  common  stock,  par  value  $1.00 per share
("Common Stock"), of the Company, at a conversion price of $17.45 per share of
Common  Stock  (which  price is subject  to  adjustment  in certain  events as
described in the Indenture).  The Firm Debentures and the Optional  Debentures
are hereinafter sometimes  collectively  referred to as the "Securities".


<PAGE>

     The Purchaser and other holders  (including  subsequent  transferees)  of
Securities  will  be  entitled  to the  benefits  of the  registration  rights
agreement,  to be  dated  as of the  Closing  Date  (as  defined  below)  (the
"Registration Rights Agreement") between the Company and the Purchaser, in the
form  attached  hereto as  Exhibit  B.  Pursuant  to the  Registration  Rights
Agreement,  the Company will agree to file with the United  States  Securities
and Exchange  Commission (the "Commission")  under the circumstances set forth
therein  a shelf  registration  statement  pursuant  to  Rule  415  under  the
Securities  Act  relating  to the resale of (i) such  Securities  and (ii) the
shares of Common Stock initially issuable upon conversion of the Securities by
holders thereof,  and to use its best efforts to cause such shelf registration
statement to be declared effective.

     The Company hereby agrees with the Purchaser as follows:

     SECTION 2. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY. The
Company represents and warrants to, and agrees with, the Purchaser that:

     (a)  A  preliminary  offering  circular,  issued  October  3,  1997  (the
   "Preliminary Offering Circular") and an offering circular, dated October 7,
   1997  (the  "Offering  Circular",  in each  case  including  the  documents
   incorporated therein by reference as described below, have been prepared in
   connection  with the offering of the  Securities and shares of Common Stock
   issuable upon conversion thereof. Any reference to the Preliminary Offering
   Circular or the Offering  Circular  shall be deemed to refer to and include
   the Company's Annual Report on Form 10-K for the fiscal year ended December
   31, 1996 and the Company's  Quarterly Reports on Form 10-Q for the quarters
   ended March 31,  1997,  and June 30, 1997,  respectively,  each having been
   filed with the Commission pursuant to the United States Securities Exchange
   Act of 1934, as amended (the "Exchange Act") on or prior to the date of the
   Preliminary Offering Circular or the Offering Circular, as the case may be,
   and any  reference  to the  Preliminary  Offering  Circular or the Offering
   Circular,  as the  case  may be,  as  amended  or  supplemented,  as of any
   specified date, shall be deemed to include (i) any documents filed with the
   Commission  pursuant to Section  13(a),  13(c) or 15(d) of the Exchange Act
   after  the  date  of the


                                      2

<PAGE>

   Preliminary Offering Circular or the Offering Circular, as the case may be,
   and prior to such specified date and (ii) any Additional Issuer Information
   (as  defined  in  Section  5(d))  furnished  by the  Company  prior  to the
   completion of the  distribution of the Securities;  and all documents filed
   under the  Exchange  Act and so deemed to be  included  in the  Preliminary
   Offering  Circular  or the  Offering  Circular,  as the case may be, or any
   amendment or supplement  thereto are  hereinafter  called the "Exchange Act
   Reports".  The Exchange  Act Reports,  when they were or are filed with the
   Commission,  conformed  or will  conform in all  material  respects  to the
   applicable  requirements  of the Exchange Act and the applicable  rules and
   regulations of the Commission thereunder. The Preliminary Offering Circular
   or the Offering Circular and any amendments or supplements  thereto and the
   Exchange  Act Reports did not and will not, as of their  respective  dates,
   contain an untrue  statement of a material fact or omit to state a material
   fact necessary in order to make the statements therein, in the light of the
   circumstances  under  which  they  were  made,  not  misleading;  PROVIDED,
   HOWEVER,  that  this  representation  and  warranty  shall not apply to any
   statements  or  omissions  made in  reliance  upon and in  conformity  with
   information  furnished in writing to the Company by the Purchaser expressly
   for use therein.

     (b) When  the  Securities  are  issued  and  delivered  pursuant  to this
   Agreement, the Securities will not be of the same class (within the meaning
   of Rule 144A under the United  States  Securities  Act of 1933,  as amended
   (the  "Securities  Act")),  as  securities  which are  listed on a national
   securities  exchange  registered  under  Section 6 of the  Exchange  Act or
   quoted in a U.S. automated inter-dealer quotation system.

     (c) The Company is not, and after giving  effect to the offering and sale
   of the Securities, will not be required to be registered or regulated as an
   "investment  company",  within the meaning of the United States  Investment
   Company Act of 1940, as amended (the "Investment Company Act").

     (d) Within the  preceding  six months,  neither the Company nor any other
   person  acting on behalf of the  Company  has offered or sold to any person
   any  Securities,  or any  securities  of the same or a similar class as the
   Securities,


                                      3

<PAGE>

   other than  Securities  offered or sold to the  Purchasers  hereunder.  The
   Company will take reasonable  precautions designed to insure that any offer
   or sale, direct or indirect, in the United States or to any U.S. person (as
   defined  in Rule 902 under the  Securities  Act) of any  Securities  or any
   substantially  similar  security  issued by the Company,  within six months
   subsequent to the date on which the distribution of the Securities has been
   completed  (as notified to the Company by Lazard Freres & Co. LLC), is made
   under  restrictions  and other  circumstances  reasonably  designed  not to
   affect  the  status of the offer and sale of the  Securities  in the United
   States and to U.S.  persons  contemplated by this Agreement as transactions
   exempt from the registration provisions of the Securities Act.

     SECTION 3. PURCHASE, SALE AND DELIVERY OF SECURITIES. On the basis of the
representations,  warranties and agreements herein  contained,  but subject to
the terms and conditions herein set forth, the Company and the Purchaser agree
that the Purchaser will purchase from the Company at the purchase price of 97%
of the principal  amount thereof the principal  amount of Firm  Debentures set
forth opposite such Purchaser's name in Schedule I hereto.

     The Company  hereby agrees to issue and sell to the Purchaser and, on the
basis of the representations,  warranties and agreements herein contained, but
subject to the terms and conditions herein set forth, the Purchaser shall have
the right to purchase from the Company,  pursuant to an option to be exercised
in the  30-day  period  commencing  on  the  date  of  this  Agreement,  up to
$18,750,000  aggregate principal amount of Optional Debentures at the purchase
price of 97% of the  principal  amount  thereof.  Optional  Debentures  may be
purchased  solely  for  the  purpose  of  covering   over-allotments  made  in
connection with the offering of the Firm Debentures.

     The Company will deliver the Firm  Debentures to you,  against payment of
the purchase price therefor by wire transfer in immediately available funds to
an  account  specified  in  writing  by the  Company.  Payment  for  the  Firm
Debentures  shall be made at the offices of  Cravath,  Swaine & Moore at 10:00
A.M.,  New York Time,  on October  14, 1997 or at such other place or time not
later  than  three  full  business  days  thereafter  as you and  the  Company
determine (the "Initial Closing Date").

     SECTION 5.  COVENANTS OF THE COMPANY.  The Company  covenants  and agrees
with the Purchaser that:

     (a) To prepare the Offering  Circular in a form  approved by you; to make
   no amendment or any  supplement  to the  Offering  Circular  which shall be

   time reasonably request, and if, at any time prior to the completion of the
   distribution of the  Securities,  any event shall have occurred as a result
   of which the  Offering  Circular  as then  amended  or  supplemented  would
   include  an  untrue  statement  of a  material  fact or omit to  state  any
   material fact  necessary in order to make the  statements  therein,  in the
   light of the  circumstances  under which they were made when such  Offering
   Circular is delivered, not misleading, or, if for any other reason it shall

   the Offering  Circular,  to notify you and upon your request to prepare and
   furnish  without charge to the Purchaser and to any dealer in securities as

   cooperation with you, to qualify the Securities for offering and sale under
   the applicable  securities laws of such states and other  jurisdictions  of
   the  United   States  as  you  may   designate,   and  will  maintain  such
   qualifications   in  effect  for  as  long  as  may  be  required  for  the
   distribution of the  Securities.  The Company will file such statements and
   reports as may be  required by the laws of each  jurisdiction  in which the

that date,  to the  accuracy  of the  statements  of the  Company  made in any
certificates  pursuant to the  provisions  hereof,  to the  performance by the
Company  of  their  obligations  hereunder  and  to the  following  additional
conditions precedent:

     (a) You shall not have advised the Company that the Offering Circular, or
   any amendment or supplement thereto,


                                      8

<PAGE>

   contains any untrue statement of fact or omits to state any fact which, you
   have  concluded,  is material and in the case of an omission is required to
   be stated  therein  or is neces  sary to make the  statements  therein  not
   misleading.

     (b) You shall have received a favorable opinion of Freedman,  Levy, Kroll
   & Simonds,  counsel for the Company, dated the Initial Closing Date, to the
   effect that:

        (i) Each of the Company,  Coeur Alaska,  Inc., Coeur Rochester,  Inc.,
     CDE Chilean Mining Corporation,  Callahan Mining  Corporation,  Coeur New
     Zealand,  Inc., and Silver Valley Resources  Corporation  (individually a
     "Subsidiary"  and  collectively   the   "Subsidiaries")   has  been  duly
     incorporated  and is validly  existing as a corporation  in good standing
     under the laws of the jurisdiction in which it is chartered or organized,
     with full corporate power and authority to own its properties and conduct
     its business as described in the Offering Circular, and is duly qualified
     to do business as a foreign corporation and is in good standing under the
     laws of each jurisdiction  which requires such  qualification  wherein it
     owns or leases material prop erties or conducts material business.

        (ii) All the  outstanding  shares of capital stock of each  Subsidiary
     have been duly and validly  authorized  and issued and are fully paid and
     nonassessable,  and,  except  as  otherwise  set  forth  in the  Offering
     Circular, all outstanding shares of capital stock of the Subsidiaries are
     owned by the Company either directly or through wholly owned subsidiaries
     free and clear of any perfected  security  interest and, to the knowledge
     of such counsel, after due inquiry, any other security interests, claims,
     liens or encumbrances.

        (iii) This Agreement and the  Registration  Rights Agreement have been
     duly authorized, executed and delivered by the Company.

        (iv) The  Securities  and the capital stock of the Company  conform in
     all  material  respects  to  the  description  thereof  contained  in the
     Offering Circular;  the Indenture has been duly authorized,  executed and


                                      9

<PAGE>

     delivered by the Company and the Trustee,  and constitutes a legal, valid
     and binding obligation of the Company  enforceable against the Company in
     accordance with its terms (subject to applicable bankruptcy,  insolvency,
     fraudulent   transfer,   reorganization,   moratorium  and  similar  laws
     affecting  creditors'  rights generally from time to time in effect,  and
     subject,   as  to  enforceability,   to  general  principles  of  equity,
     regardless of whether such  enforceability  is considered in a proceeding
     in law or at equity);  and the Securities have been duly authorized,  and
     when executed and  authenticated in accordance with the provisions of the
     Indenture and delivered to and paid for by the Purchaser pursuant to this
     Agreement,  the Securities will  constitute the legal,  valid and binding
     obligations  of the  Company  entitled to the  benefits of the  Indenture
     enforceable  against the Company in accordance  with their terms (subject
     to    applicable    bankruptcy,    insolvency,    fraudulent    transfer,
     reorganization,  moratorium and similar laws affecting  creditors' rights
     generally from time to time in effect, and subject, as to enforceability,
     to  general   principles   of   equity,   regardless   of  whether   such
     enforceability is considered in a proceeding in law or at equity).

        (v) The shares of Common Stock  initially  issuable upon conversion of
     the  Securities  have been duly and validly  authorized  and reserved for
     issuance upon such conversion and, when issued upon  conversion,  will be
     validly issued, fully paid and nonassessable.

        (vi) Such counsel has no reason to believe that the Offering  Circular
     includes  any untrue  statement  of a  material  fact or omits to state a
     material fact necessary to make the statements  therein,  in the light of
     the circumstances under which they were made, not misleading.

        (vii) The  statements  set forth in the  Offering  Circular  under the
     headings  "Description  of the Debentures"  and,  "Description of Capital
     Stock",  insofar  as such  statements  constitute  a summary of the legal
     matters,  documents or proceedings referred to therein fairly present the
     information called for with


                                      10

<PAGE>

     respect to such legal matters, documents and proceedings.

        (viii)   No   consent,   approval,   authorization,   order,   filing,
     registration  or  qualification  of or with  any  court  or  governmental
     authority or agency is required for the issue and sale of the  Securities
     or the consummation of the  transactions  contemplated by this Agreement,
     except such as may be required and have been  obtained  under the Act and
     such as may be  required  under  state  securities  or Blue  Sky  laws in
     connection with the distribution of the Securities by the Purchaser; and,
     the issue and sale of the  Securities,  the execution and delivery of the
     Indenture,  this Agreement and the  Registration  Rights Agreement by the
     Company and the consummation of the transactions  contemplated herein and
     therein  will not  conflict  with or  constitute  a breach of, or default
     under any contract,  indenture,  mortgage, loan agreement, note, lease or
     other instrument known to such counsel to which the Company or any of its
     subsidiaries  is a party or by which it or any of them may be bound,  nor
     will such action result in any violation of the provisions of the charter
     or by-laws  of the  Company,  or any law,  administrative  regulation  or
     administrative  or court decree or order applicable to the Company or any
     of its subsidiaries.

        (ix) To the best  knowledge of such counsel and except as set forth in
     the Offering Circular,  there is no pending or threatened action, suit or
     proceeding before any court or governmental agency,  authority or body or
     any arbitrator involving the Company or any of its subsidiaries which, if
     determined  adversely  to the Company or any of its  subsidiaries,  would
     individually  or in the aggregate  have a material  adverse effect on the
     current or future consolidated  financial position,  stockholders' equity
     or results of operation of the Company and its  subsidiaries,  taken as a
     whole.

        (x) The Exchange Act Reports and any other  documents  incorporated by
     reference in the Offering Circular as amended or supplemented (other than
     the financial  statements and related schedules therein, as to which such
     counsel need express no opinion), when


                                      11

<PAGE>

     they were filed with the Commission,  complied as to form in all material
     respects  with the  requirements  of the Exchange  Act, and the rules and
     regulations of the Commission thereunder;  and such counsel has no reason
     to believe that any of such documents, when they were so filed, contained
     an untrue  statement  of a  material  fact or omitted to state a material
     fact necessary in order to make the statements  therein,  in the light of
     the circumstances  under which they were made when such documents were so
     filed, not misleading.

        (xi)  Assuming  (i)  the  accuracy  of,  and   compliance   with,  the
     representations,  warranties  and  covenants  by the  Company in Sections
     2(b),  2(d),  2(e), 5(d), 5(e) and 5(f) and by you contained in Section 3
     and  Annex A of this  Agreement,  (ii)  the  compliance  by you  with the
     offering  and  transfer  procedures  and  restrictions  described  in the
     Offering  Circular and the Purchase  Agreement and (iii) the accuracy of,
     and  compliance  with, the  representations,  warranties and covenants of
     each of the  purchasers  to whom you initially  resell the  Securities as
     specified in the Offering  Circular,  no  registration  of the Securities
     under the Securities Act, and no qualification of the Indenture under the
     TIA with  respect  thereto,  is  required  for the  offer and sale by the
     Company  and the  offer  and  initial  resale  of the  Securities  by the
     Purchasers  in the  manner  contemplated  by  this  Agreement;  PROVIDED,
     HOWEVER,  we  express  no  opinion  as to any  subsequent  resale  of the
     Securities.

        (xii) The Company is not required to be  registered or regulated as an
     "investment company" within the meaning of the Investment Company Act.

In rendering such opinion,  such counsel may rely (x) as to matters  involving
the application of laws of any  jurisdiction  other than the State of Idaho or
the United  States,  to the extent  they deem  proper  and  specified  in such
opinion,  upon the opinion of other counsel of good standing whom they believe
to be reliable and who are  satisfactory  to counsel for the Purchaser and (y)
as to matters of fact,  to the extent they deem  proper,  on  certificates  of
responsible  officers of the Company and public  officials.  References to the
Offering Circular in this paragraph (c) include any supplements thereto at the
Closing Date.


                                      12

     (c) You shall have received from Cravath, Swaine & Moore, counsel for the
   Purchaser, an opinion, dated the Initial Closing Date, with respect to such
   matters as you may reasonably request.

     (d) You  shall  have  received  from the  President  or any  Senior  Vice
   President and a principal  financial or accounting officer of the Company a
   certificate, dated the Initial Closing Date, in which such officers, to the
   best of their knowledge and after reasonable investigation, shall state (i)
   such officers have carefully examined the Offering Circular,  (ii) in their
   opinion,  as of its date, the Offering  Circular did not include any untrue
   statement  of a  material  fact and did not omit to state a  material  fact
   necessary to make the statements therein, in the light of the circumstances
   under which they were made,  not  misleading  and since such date, no event
   has occurred  which should have been set forth in a supplement or amendment
   to the  Offering  Circular,  (iii)  that  there  has not  been,  since  the
   respective dates as of which information is given in the Offering Circular,
   any material  adverse  change in the  condition,  financial  or  otherwise,
   earnings,  business  or  prospects  of the  Company  and  its  subsidiaries
   considered  as a whole,  whether or not arising in the  ordinary  course of
   business  and  (iv)  the  representations  and  warranties  of the  Company
   contained  in Section 2 are true and correct with the same force and effect
   as though  made on and as of the Initial  Closing  Date and the Company has
   complied with all agreements and satisfied all conditions on its part to be
   performed or satisfied hereunder at or prior to the Initial Closing Date.

     (e) You shall have received from Ernst & Young, independent auditors, two
   letters,  the first  dated the date of this  Agreement  and the other dated
   such Initial Closing Date, addressed to the Purchaser, substantially in the
   form of Annex B hereto with such variations as are reasonably acceptable to
   you.

     (f) At the Initial Closing Date counsel for the Purchaser shall have been
   furnished with such further  information,  other  documents and opinions as
   they may reasonably require.


                                      13

     (g) The Common Stock  issuable upon  conversion of the  Securities  shall
   have been duly listed,  subject to notice of issuance,  on the New York and
   Pacific Stock Exchanges.

     (h)  Subsequent to the execution and delivery of this Agreement and prior
   to the Closing Date, there shall not have been any  downgrading,  nor shall
   any notice have been given of any intended or potential  downgrading  or of
   any review for a possible  change that does not indicate  the  direction of
   the possible change, in the rating accorded any of the Company's securities
   (including the Securities) by any "nationally recognized statistical rating
   organization", as such term is defined for purposes of Rule 436(g)(2) under
   the Act.

     The  several  obligations  of the  Purchaser  to  purchase  the  Optional
Debentures  hereunder are subject to (i) the accuracy of and  compliance  with
the  representations  and warranties of the Sellers contained herein on and as
of the Option Closing Date, (ii)  satisfaction on and as of the Option Closing
Date of the conditions  set forth in subsections  (a) to (i) of this Section 6
inclusive  (and for  purposes  thereof each  reference  therein to the Initial
Closing  Date shall be deemed to refer to the Option  Closing  Date) and (iii)
the  absence of  circumstances  on or prior to the Option  Closing  Date which
would permit termination of this Agreement pursuant to Section 10.

     SECTION 7. PAYMENT OF EXPENSES. The Company will pay all costs, expenses,
fees,  disbursements and taxes incident to (i) the preparation by the Company,
printing and distribution of the Preliminary  Offering Circular,  the Offering
Circular  and all  amendments  and  supplements  to either  of them,  (ii) the

the fees and expenses of the Registrar and Transfer  Agent for the  Securities
and its  counsel  and  (viii)  the  performance  by the  Company  of its other
obligations under this Agreement.

     If the sale of the  Securities  provided  for  herein is not  consummated
because of the  failure to satisfy any  condition  to the  obligations  of the
Purchaser set forth in Section 6 hereof,  because of any termination  pursuant
to Section 10 hereof or because of any  refusal,  failure or  inability of the
Company to perform any agreement  herein or comply with any  provision  hereof
other  than by  reason  of a  default  by the  Purchaser,  the  Company  shall
reimburse you for all of your  out-of-pocket  expenses  incurred in connection
with marketing and preparing for the offering of the Securities, including the
reasonable fees and disbursements of counsel for the Purchaser.

     SECTION 8. INDEMNIFICATION AND CONTRIBUTION.

     (a) The Company  agrees to indemnify  and hold harmless the Purchaser and
each person,  if any, who controls the Purchaser  within the meaning of either
Section 15 of the Act or Section 20 of the Exchange  Act, from and against any
and all  losses,  claims,  damages  and  liabilities  (or  actions  in respect
thereof) (including,  without limiting the foregoing, the reasonable legal and
other  expenses  incurred in  connection  with  investigating  or defending or
preparing to defend or appearing as a third party witness in  connection  with
any such loss,  claim,  damage,  liability  or action,  as such  expenses  are
incurred)  arising out of or based on any untrue  statement or alleged  untrue
statement  of a  material  fact  contained  in the  Offering  Circular  or any
Preliminary  Offering Circular,  or caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the  statements  therein not  misleading,  except insofar as such losses,
claims,  damages,  liabilities  or  expenses  are  caused  by any such  untrue
statement or omission or alleged  untrue  statement or omission based upon the
following  information  furnished  to the  Company  by you  in  (i)  the  last
paragraph of text on the cover page of the Offering  Circular  concerning  the
terms of the offering by the Purchaser,  (ii) the first paragraph on page 3 of
the Offering  Circular  concerning  over-allotment  and  stabilization  by the
Purchaser  and (iii) the third  paragraph  of text under the caption  "Plan of
Distribution" in the Offering Circular concerning the terms of


                                      15

<PAGE>

the  offering  by  the  Purchaser  (all  of  the  foregoing  the  "Purchaser's
Information").  This indemnity  agreement will be in addition to any liability
which the Company may otherwise have to the persons  referred to above in this
Section 8(a).

     (b) The Purchaser agrees to indemnify and hold harmless the Company,  the
officers and  directors  of the Company and each person,  if any, who controls
the Company  within the meaning of either  Section 15 of the Act or Section 20
of the Exchange Act from and against any and all losses,  claims,  damages and
liabilities (or actions in respect  thereof) caused by any untrue statement or
alleged untrue statement of a material fact contained in the Offering Circular
or any  Preliminary  Offering  Circular,  or caused by any omission or alleged
omission to state  therein a material  fact  required to be stated  therein or
necessary  to make the  statements  therein  not  misleading,  but  only  with
reference to the Purchaser's Information.  This indemnity agreement will be in
addition  to any  liability  which the  Purchaser  may  otherwise  have to the
persons referred to above in this Section 8(b).

     (c) In case any  action or  proceeding  (including  any  governmental  or
regulatory  investigation  or  proceeding)  shall be instituted  involving any
person in respect of which  indemnity may be sought  pursuant to either of the
two preceding  paragraphs,  such person  (hereinafter  called the  indemnified
party) shall  promptly  notify the person  against whom such  indemnity may be
sought (hereinafter called the indemnifying  party) in writing;  however,  the
omission to so notify the  indemnifying  party shall relieve the  indemnifying
party from liability only to the extent prejudiced  thereby.  The indemnifying
party,  upon  request of the  indemnified  party,  shall  assume  the  defense
thereof,  including the employment of counsel  reasonably  satisfactory to the
indemnified  party to represent the indemnified  party and any others that the
indemnifying  party may designate and shall pay the fees and  disbursements of
such counsel related to such proceeding.  In any such action or proceeding any
indemnified party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such indemnified party
unless  (i) the  indemnifying  party  and the  indemnified  party  shall  have
mutually  agreed to the retention of such counsel or (ii) the named parties to
any  such  proceeding  (including  any  impleaded  parties)  include  both the
indemnifying  party  and the  indemnified  party  and  representation  of both
parties by the same counsel would be inappropriate due to actual


                                      16

<PAGE>

or potential  differing  interests  between them.  It is  understood  that the
indemnifying  party shall not, in  connection  with any  proceeding or related
proceedings in the same  jurisdiction,  be liable for (a) the reasonable  fees
and expenses of more than one separate firm (in addition to any local counsel)
for the  Purchaser and all persons,  if any, who control the Purchaser  within
the meaning of either Section 15 of the Act or Section 20 of the Exchange Act,
(b) the  reasonable  fees and  expenses  of more  than one  separate  firm (in
addition  to any local  counsel)  for the  Company,  its  directors,  and each
person,  if any, who  controls  the Company  within the meaning of either such
Section of the Act, and that all fees and expenses to be paid pursuant to each
of  clauses  (a) and (b) of this  sentence  shall  be  reimbursed  as they are
incurred.  In the case of any such  separate  firm for the  Purchaser and such
control persons of the Purchaser,  such firm shall be designated in writing by
Lazard  Freres  & Co.  LLC.  In the  case of any  such  separate  firm for the
Company, and such directors, officers and control persons of the Company, such
firm shall be designated in writing by the Company.

     (d) If the indemnification provided for in this Section 8 is insufficient
or  unavailable  to an  indemnified  party in respect of any  losses,  claims,
damages or liabilities  (or actions in respect  thereof)  referred to therein,
then each indemnifying  party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified  party as a
result of such losses, claims,  damages,  liabilities and expenses (i) in such
proportion as is appropriate to reflect the relative  benefits received by the
Company on the one hand and the  Purchaser  on the other from the  offering of
the Securities or (ii) if the  allocation  provided by clause (i) above is not
permitted by applicable law or if the  indemnified  party shall have failed to
the prejudice of the indemnifying party to give the notice required by Section
8(c), in such  proportion as is  appropriate  to reflect not only the relative
benefits  referred to in clause (i) above but also the  relative  fault of the
Company on the one hand and the Purchaser on the other in connection  with the
statements  or  omissions  which  resulted in such  losses,  claims,  damages,
liabilities   or   expenses,   as  well  as  any  other   relevant   equitable
considerations.  The relative benefits received by the Company on the one hand
and the  Purchaser on the other shall be deemed to be in the same  proportions
as the  total net  proceeds  from the  offering  (before  deducting  expenses)
received  by  the  Company  bear  to  the  total  underwriting  discounts  and
commission  received by the Purchaser,  in each case as set


                                      17

<PAGE>

forth in the table on the cover page of the  Offering  Circular.  The relative
fault of the Company on the one hand and the  Purchaser  on the other shall be
determined by reference to, among other things,  whether the untrue or alleged
untrue  statement of a material  fact or the  omission or alleged  omission to
state a material fact relates to information supplied by the Company or by the
Purchaser and the parties, relative intent,  knowledge,  access to information
and opportunity to correct or prevent such statement or omission.

     (e) The  Company  and the  Purchaser  agree that it would not be just and
equitable if contribution pursuant to Section 8(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the  equitable   considerations  referred  to  in  the  immediately  preceding
paragraph.  The amount paid or payable by an indemnified  party as a result of
the losses,  claims,  damages or liabilities  (or actions in respect  thereof)
referred to in the immediately  preceding paragraph shall be deemed to include
any legal or other expenses  reasonably  incurred by such indemnified party in
connection  with   investigating  or  defending  any  such  action  or  claim.
Notwithstanding  the  provisions  of  Section  8(e),  in no  event  shall  the
Purchaser  be  required  to  contribute  any amount in excess of the amount by
which  the  total  price  at  which  the  Securities  underwritten  by it  and
distributed to the public were offered to the public exceeds the amount of any
damages which such  Purchaser has otherwise  been required to pay by reason of
such untrue or alleged untrue  statement or omission or alleged  omission.  No
person guilty of fraudulent  misrepresentation  (within the meaning of Section
11(f) of the Act) shall be  entitled to  contribution  from any person who was
not guilty of such fraudulent misrepresentation.

     SECTION  9.   REPRESENTATIONS,   WARRANTIES  AND  AGREEMENTS  TO  SURVIVE
DELIVERY.  All  representations,  warranties and  agreements  contained in the
Agreement,  or contained in certificates of officers of the Company  submitted
pursuant hereto, including indemnity and contribution agreements, shall remain
operative and in full force and effect,  regardless of any termination of this
Agreement,  or any investigation,  or any statement as to the results thereof,
made by or on behalf of the Purchaser or any person  controlling the Purchaser
or by or on behalf of the Company,  its  officers or directors or  controlling
persons, and shall survive acceptance of and payment for Securities hereunder.

     SECTION 10. TERMINATION.  This Agreement may be terminated for any reason
at any time prior to the  delivery of and payment  for the  Securities  on the
Initial Closing Date or the Option Closing Date, as the case may be, by Lazard
Freres & Co. LLC upon the giving of written notice of such  termination to the
Company,  if prior to such time (i) there has been, since the respective dates
as of which  information  is  given in the  Offering  Circular,  any  material
adverse change in the condition, financial or otherwise, earnings, business or
prospects of the Company and its subsidiaries  considered as a whole,  whether
or not arising in the  ordinary  course of business or (ii) there has occurred
any  outbreak or  escalation  of  hostilities  or other  calamity or crisis or
material change in existing  national or international  financial,  political,
economic or securities  market  conditions,  the effect of which is such as to
make it,  in the  judgment  of  Lazard  Freres  & Co.  LLC,  impracticable  or
inadvisable  to  market  the  Securities  in the  manner  contemplated  in the
Offering  Circular or enforce  contracts  for the sale of the  Securities,  or
(iii) trading of the Common Stock of the Company has been suspended by the New
York Stock  Exchange,  or the Commission,  or trading  generally on either the
American Stock Exchange or the New York Stock Exchange has been suspended,  or
minimum or maximum  prices for trading have been fixed,  or maximum ranges for
prices for securities  have been  required,  by either of said exchanges or by
order of the  Commission  or any other  governmental  authority,  or a banking
moratorium has been declared by either Federal or New York authorities. In the
event of any such  termination,  the  provisions  of Section 7, the  indemnity
agreement  and  contribution  provisions  set  forth  in  Section  8,  and the
provisions of Sections 9 and 13 shall remain in effect.

     SECTION 11. NOTICES. All notices and other communications hereunder shall
be in  writing  and  shall be  deemed  to have  been  duly  given if mailed or
transmitted  by  any  standard  form  of  telecommunication.  Notices  to  the
Purchaser shall be directed to you c/o Lazard Freres & Co. LLC, 30 Rockefeller
Plaza, New York, NY 10020, Attention: Syndicate Department; and notices to the
Company  shall be  directed to it at 505 Front  Avenue  Coeur  d'Alene,  Idaho

Treasurer.

     SECTION 12. PARTIES.  This Agreement shall inure to the benefit of and be

   sold within the United States or to, or for the account or benefit of, U.S.
   persons  (i) as part of their  distribution  at any time or (ii)  otherwise
   until 40 days after the later of the  commencement  of the offering and the
   closing  date,  except in either case in accordance  with  Regulation S (or
   Rule 144A if available) under the Securities Act. Terms used above have the
   meaning given to them by Regulation S."

Terms used in this paragraph have the meanings given to them by Regulation S.

     The Purchaser  further  agrees that it has not entered and will not enter
into any contractual  arrangement with respect to the distribution or delivery
of the  Securities,  except  with its  affiliates  or with the  prior  written

Kingdom except to persons whose ordinary activities involve them in acquiring,
holding,  managing or disposing of investments (as principal or agent) for the
purposes of their  businesses  or  otherwise in  circumstances  which have not
resulted  and will not result in an offer to the public in the United  Kingdom
within the meaning of the Public Offers of Securities Regulations 1995, (b) it
has complied, and will comply, with all applicable provisions of the Financial
Services Act of 1986 of Great  Britain with respect to anything  done by it in
relation to the Securities in, from or otherwise involving the United Kingdom,
and (c) it has only  issued or passed on and will only issue or pass on in the
United Kingdom any document  received by it in connection with the issuance of
the  Securities to a person who is of a kind described in Article 11(3) of the
Financial  Services Act 1986 (Investment  Advertisements)  (Exemptions)  Order
1996 of Great  Britain  or is a  person  to whom the  document  may  otherwise
lawfully be issued or passed on.

     (4) The Purchaser  agrees that it will not offer,  sell or deliver any of
the  Securities  in any  jurisdiction  outside the United  States except under
circumstances that will result in compliance with the applicable laws thereof,
and that it will take at its own expense whatever action is required to permit
its purchase and resale of the Securities in such jurisdictions. The Purchaser
understands  that no action has been taken to permit a public  offering in any
jurisdiction outside the United States where action would be required for such
purpose.  The Purchaser agrees to cause any advertisement of the Securities to
be published in any  newspaper or periodical or posted in any public place and
to issue any  circular  relating to the  Securities,  only at its own risk and
expense.

                                                                 EXHIBIT 10(b)

   shares of Common Stock.

     SECTION 2. SHELF  REGISTRATION.  (a) The  Company  shall,  within 90 days
   following  the  date  of  original  issuance  (the  "Issue  Date")  of  the
   Securities,  file  with  the  Commission  a  Shelf  Registration  Statement
   relating to the offer and sale of the Registrable Securities by the Holders
   from time to time in accordance with the methods of distribution elected by

   Statement to be declared  effective  under the Act within 150 calendar days
   after the Issue Date; PROVIDED,  however,  that no Holder shall be entitled
   to have  the  Registrable  Securities  held  by it  covered  by such  Shelf
   Registration unless such Holder is an Electing Holder.

     (b) The Company shall use its best efforts:

     (i) to keep the Shelf Registration  Statement con tinuously  effective in
   order to permit the Prospectus forming part thereof to be usable by Holders
   until October 31, 1999 or such shorter  period that will terminate upon the
   earlier of the following:  (A) when all the Securities covered by the Shelf
   Registration  Statement  have been sold pursuant to the Shelf  Registration

<PAGE>

   Stock issued upon  conversion of any such Securities that had not been sold
   pursuant to the Shelf Registration Statement have been sold pursuant to the
   Shelf Registration Statement (in either such case, such period being called
   the "Effectiveness Period"); and

     (ii) after the date the Shelf  Registration  Statement becomes effective,
   within 35 days after the  request of any holder of  Registrable  Securities
   that is not then an  Electing  Holder,  to take any  action  necessary  and
   required by law to enable such holder to use the Prospectus  forming a part
   thereof  for  resales  of  Registrable   Securities,   including,   without
   limitation,  any action  necessary  to  identify  such  holder as a selling
   securityholder in the Shelf Registration Statement; PROVIDED, HOWEVER, that
   nothing in this subparagraph shall relieve such holder of the obligation to
   return a completed  and signed Notice and  Questionnaire  to the Company in
   accordance with Section 3(a)(2) hereof; and

     (iii) if at any  time,  the  Securities,  pursuant  to  Article  V of the
   Indenture,  are convertible  into securities  other than Common Stock,  the
   Company shall,  or shall cause any successor  under the Indenture to, cause
   such securities to be included in the Shelf Registration Statement no later
   than the date on which the  Securities  may then be  convertible  into such
   securities.

     The Company shall be deemed not to have used its best efforts to keep the
Shelf  Registration  Statement  effective  during the requisite  period if the
Company  voluntarily  takes  any  action  that  would  result  in  Holders  of
Registrable  Securities  covered  thereby not being able to offer and sell any
such  Registrable  Securities  during that  period,  unless (i) such action in
required by applicable law, or (ii) the continued  effectiveness  of the Shelf
Registration  Statement  would  require  the  Company  to  disclose a material
financing,  acquisition  or other  corporate  trans  action,  and the Board of
Directors  shall have  determined in good faith that such disclosure is not in
the best interests of the Company and its  stockholders;  provided that in the
case of clause (i) above, the Company thereafter must promptly comply with the
requirements of paragraph 3(j) below, if applicable and in the case of clauses
(i) and (ii) above,  the  Company  shall be entitled to suspend the use of 


                                      5

<PAGE>

any prospectus  forming a part of an effective  Registration  Statement  under
this Section 2 for a reasonable period of time (a "DELAY PERIOD"), except that
the  aggregate  number  of days  included  in all  Delay  Periods  during  any
consecutive  12 months shall not exceed the  aggregate of 90 days  (whether or
not consecutive).

     SECTION  3.  REGISTRATION  PROCEDURES.   In  connection  with  any  Shelf
Registration Statement, the following provisions shall apply:

     (a) (1) Not less than 30 calendar days prior to the Effective Time of the
Shelf  Registration   Statement,   the  Company  shall  mail  the  Notice  and
Questionnaire  to the holders of  Registrable  Securities.  No holder shall be
entitled  to be named as a selling  securityholder  in the Shelf  Registration
Statement as of the Effective Time, and no holder shall be entitled to use the
Prospectus forming a part thereof for resales of Registrable Securities at any
time,  unless  such  holder has  returned a  completed  and signed  Notice and
Questionnaire  to the Company by the deadline for response set forth  therein;
PROVIDED,  HOWEVER,  holders of Registrable  Securities shall have at least 28
calendar  days from the date on which the  Notice and  Questionnaire  is first
mailed  to  such  holders  to  return  a  completed   and  signed  Notice  and
Questionnaire to the Company.

        (2) After the Effective Time of the Shelf Registration Statement,  the
     Company shall,  upon the request of any holder of Registrable  Securities
     that  is  not  then  an  Electing  Holder,  promptly  send a  Notice  and
     Questionnaire  to such holder.  The Company shall not be required to take
     any action to name such holder as a selling  securityholder  in the Shelf
     Registration  Statement  or to enable such  holder to use the  Prospectus
     forming a part thereof for resales of Registrable  Securities  until such
     holder has returned a completed  and signed Notice and  Questionnaire  to
     the Company.

        (3) The term  "Electing  Holder" shall mean any holder of  Registrable
     Securities   that  has  returned  a  completed   and  signed  Notice  and
     Questionnaire  to the  Company  in  accordance  with  Section  3(a)(1) or
     3(a)(2) hereof.

   and each amendment thereof and each amendment or supplement, if any, to the
   Prospectus included therein.

     (c) The Company  shall  promptly  take such action as may be necessary so
   that (i) any Shelf Registration Statement and any amendment thereto and any
   Prospectus  forming part thereof and any  amendment or  supplement  thereto
   (and each report or other  document  incorporated  therein by  reference in
   each case)  complies in all material  respects with the  Securities Act and
   the Exchange Act and the respective rules and regulations thereunder,  (ii)
   any Shelf  Registration  Statement and any amendment thereto does not, when
   it becomes  effective,  contain an untrue  statement of a material  fact or
   omit to state a material fact required to be stated therein or necessary to
   make the statements therein not misleading and (iii) any Prospectus forming
   part of any Shelf Registration  Statement,  and any amendment or supplement
   to such Prospectus, does not include an untrue statement of a material fact
   or omit to state a material fact necessary in order to make the statements,
   in the  light  of  the  circumstances  under  which  they  were  made,  not
   misleading.

     (d) (1) The Company shall advise the Purchaser and, in the case of clause
   (i), the Electing  Holders,  and, if requested by the Purchaser or any such
   Electing Holder, confirm such advice in writing:

        (i) when a Shelf Registration  Statement and any amendment thereto has
     been filed with the Commission and when the Shelf Registration  Statement
     or any post-effective amendment thereto has become effective; and

        (ii) of any request by the Commission for amendments or supplements to
     the Shelf  Registration  Statement or the Prospectus  included therein or
     for additional information.

     (2) The Company shall advise the Purchaser and the Electing  Holders and,

<PAGE>

        (i) the  issuance  by the  Commission  of any  stop  order  suspending
     effectiveness  of the Shelf  Registration  Statement or the initiation of
     any proceedings for that purpose;

        (ii) the receipt by the Company of any  notification  with  respect to
     the suspension of the  qualification  of the securities  included therein
     for sale in any jurisdiction or the initiation of any proceeding for such
     purpose; and

        (iii) the  happening  of any event  that  requires  the  making of any
     changes in the Shelf Registration Statement or the Prospectus so that, as
     of such date, the Shelf Registration  Statement and the Prospectus do not
     contain an untrue statement of a material fact and do not omit to state a
     material  fact  required to be stated  therein or  necessary  to make the
     statements  therein  (in the  case of the  Prospectus,  in  light  of the
     circumstances  under which they were made) not  misleading  (which advice
     shall  be  accompanied  by an  instruction  to  suspend  the  use  of the
     Prospectus  until the requisite  changes have been made). 

     (e) The Company  shall use its best efforts to prevent the issuance  and,
   if  issued,  to  obtain  the  withdrawal,   of  any  order  suspending  the
   effectiveness of any Shelf Registration  Statement at the earliest possible

   Holder so requests in writing,  all reports,  other  documents and exhibits

   the Electing  Holders of  Registrable  Securities  in  connection  with the
   offering and sale of the Registrable  Securities  covered by the Prospectus
   or any  amendment  or  supplement  thereto  during  the Shelf  Registration
   Period.

     (h) Prior to any offering of Registrable Securities pursuant to any Shelf
   Registration Statement,  the Company shall register or qualify or cooperate
   with the Electing  Holders of Registrable  Securities  included therein and
   their   respective   counsel  in  connection   with  the   registration  or
   qualification of such  Registrable  Securities for offer and sale under the
   securities  or, if  required,  blue sky laws of such  jurisdictions  in the
   United States as any such Electing  Holders  reasonably  request in writing
   and do any and all other acts or things  necessary  or  advisable to enable
   the  offer and sale in such  jurisdictions  of the  Registrable  Securities
   covered by such Shelf Registration Statement; PROVIDED, HOWEVER, that in no
   event  shall  the  Company  be  obligated  to  (i)  qualify  as  a  foreign
   corporation or as a dealer in securities in any jurisdiction where it would
   not  otherwise  be required to so qualify but for this Section  3(h),  (ii)
   file any general consent to service of process in any jurisdiction where it
   is not as of the date  hereof  then so subject or (iii)  subject  itself to
   taxation in any such jurisdiction if it is not so subject.

     (i) Unless any Registrable  Securities  shall be in book-entry only form,
   the  Company  shall  cooperate  with the  Electing  Holders of  Registrable
   Securities  to   facilitate   the  timely   preparation   and  delivery  of
   certificates representing Registrable Securities to be sold pursuant to any
   Shelf  Registration  Statement free of any restrictive  legends and in such
   permitted  denominations  and registered in such names as Electing  Holders
   may request in connection with the sale of Registrable  Securities pursuant
   to such Shelf Registration Statement.

     (j)  Upon  the  occurrence  of  any  event   contemplated   by  paragraph
   3(c)(2)(iii)  above,  the Company shall promptly


                                      9

<PAGE>

   prepare a post-effective  amendment to any Shelf Registration  Statement or
   an  amendment or  supplement  to the related  Prospectus  or file any other
   required  document so that,  as  thereafter  delivered to purchasers of the
   Registrable Securities included therein, the Prospectus will not include an
   untrue  statement  of a material  fact or omit to state any  material  fact
   necessary to make the statements therein, in the light of the circumstances
   under which they were made,  not  misleading.  If the Company  notifies the
   Electing  Holders of the occurrence of any event  contemplated by paragraph
   3(c)(2)(iii)  above,  the  Electing  Holders  shall  suspend the use of the
   Prospectus until the requisite changes to the Prospectus have been made.

     (k) Not later than the effective date of any Shelf Registration Statement
   hereunder,  the Company  shall  provide a CUSIP  number for the  Securities
   registered under such Shelf Registration Statement.

     (l) The Company shall use its best efforts to comply with all  applicable
   rules and regulations of the Commission, and to make generally available to
   its securityholders as soon as practicable, but in any event not later than
   eighteen  months  after (i) the  effective  date (as defined in Rule 158(c)
   under the Securities  Act) of the Shelf  Registration  Statement,  (ii) the
   effective date of each  post-effective  amendment to the Shelf Registration
   Statement,  and  (iii)  the date of each  filing  by the  Company  with the
   Commission  of an  Annual  Report  on Form  10-K  that is  incorporated  by
   reference in the Shelf Registration  Statement, an earning statement of the
   Company  and  its  sub  sidiaries  complying  with  Section  11(a)  of  the
   Securities Act and the rules and  regulations of the Commission  thereunder
   (including, at the option of the Company, Rule 158). 

     (m)  Not  later  than  the  Effective  Time  of  the  Shelf  Registration
   Statement,  the Company shall cause the Indenture to be qualified under the
   Trust  Indenture Act; in connection  with such  qualification,  the Company
   shall  cooperate  with the Trustee  under the  Indenture  and the  Electing
   Holders  (as  defined  in the  Indenture)  to effect  such  changes  to the
   Indenture  as may be required  for such  Indenture  to be so  qualified  in
   accordance with the terms of the Trust Indenture Act; and the Company shall
   execute,  and shall use all  reasonable  efforts  to cause the  Trustee  to
   execute,  all documents that may be required to effect such changes and all
   other  forms and  documents  required  to be filed with the  Commission  to
   enable such Indenture to be so


                                      10

<PAGE>

   qualified  in a timely  manner.  In the event  that any such  amendment  or
   modification referred to in this Section 3(m) involves the appointment of a
   new trustee  under the  Indenture,  the Company shall appoint a new trustee
   thereunder pursuant to the applicable provisions of the Indenture.

     (n)  The  Company  may  require  each  Electing   Holder  of  Registrable
   Securities  to be sold  pursuant  to any Shelf  Registration  Statement  to
   furnish to the Company such  information  regarding the Electing Holder and
   the  distribution  of such  Registrable  Securities  as may be  required by
   applicable  law or  regulation  for  inclusion  in such Shelf  Registration
   Statement  and  the  Company  may  exclude  from  such   registration   the
   Registrable  Securities  of any Electing  Holder that fails to furnish such
   information within a reasonable time after receiving such request.

     (o) The Company shall, if requested, promptly include or incorporate in a
   Prospectus  supplement or post-effective  amendment to a Shelf Registration
   Statement,  such information as the Managing Underwriters  reasonably agree
   should be included  therein and to which the  Company  does not  reasonably
   object and shall make all required filings of such Prospectus supplement or
   post-effective  amendment as soon as practicable after they are notified of
   the matters to be included or incorporated in such Prospectus supplement or
   post-effective amendment.

     (p) The Company  shall enter into such  customary  agreements  (including
   underwriting  agreements in customary  form) to take all other  appropriate
   actions  in  order  to  expedite  or  facilitate  the  registration  or the
   disposition of the Registrable Securities,  and in connection therewith, if
   an  underwriting  agreement  is  entered  into,  cause the same to  contain
   indemnification  provisions and procedures substantially identical to those
   set forth in Section 5 (or such other provisions and procedures  acceptable
   to the  Managing  Underwriters,  if any) with  respect to all parties to be
   indemnified pursuant to Section 5.

     (q) The Company shall:

        (i) make reasonably  available for inspection by the Electing  Holders
     of Registrable  Securities to be registered  thereunder,  any underwriter
     participating in any disposition pursuant to such


                                      11

<PAGE>

     Shelf Registration Statement, and any attorney, accountant or other agent
     retained by such Electing  Holders or any such  underwriter  all relevant
     financial and other records, pertinent corporate documents and properties
     of the Company and its subsidiaries;

        (ii) cause the  Company's  officers,  directors  and employees to make
     reasonably available for inspection all relevant  information  reasonably
     requested by such  Electing  Holders or any such  underwriter,  attorney,
     accountant  or agent in  connection  with  any  such  Shelf  Registration
     Statement,  in each case,  as is  customary  for  similar  due  diligence
     examinations;  PROVIDED, HOWEVER, that any information that is designated
     in writing by the Company,  in good faith, as confidential at the time of
     delivery of such information  shall be kept confidential by such Electing
     Holders or any such underwriter,  attorney,  accountant or agent,  unless
     such disclosure is made in connection with a court proceeding or required
     by law, or such information  becomes available to the public generally or
     through  a  third   party   without   an   accompanying   obligation   of
     confidentiality;

        (iii) make such representations and warranties to the Electing Holders
     of Registrable Securities registered thereunder and the underwriters,  if
     any, in form,  substance and scope as are customarily made by the Company
     to underwriters in primary  underwritten  offerings and covering  matters
     including, but not limited to, those set forth in the Purchase Agreement;

        (iv) obtain  opinions  of counsel to the  Company and updates  thereof
     (which  counsel and  opinions  (in form,  scope and  substance)  shall be
     reasonably  satisfactory  to  the  Managing  Underwriters,   if  any)  in
     customary form addressed to each Electing Holder and the underwriters, if
     any,  covering  such  matters  as are  customarily  covered  in  opinions
     requested  in  underwritten  offerings  and such other  matters as may be
     reasonably  requested by such Electing Holders and underwriters (it being
     agreed  that  the  matters  to


                                      12

<PAGE>

     be covered by such opinion or written statement by such counsel delivered
     in connection with such opinions shall include in customary form, without
     limitation, as of the date of the opinion and as of the effective date of
     the Shelf Registration Statement or most recent post-effective  amendment
     thereto,  as the case may be, the  absence  from such Shelf  Registration
     Statement  and  the  prospectus  included  therein,  as then  amended  or
     supplemented,  including the documents incorporated by reference therein,
     of an  untrue  statement  of a  material  fact or the  omission  to state
     therein a material  fact  required to be stated  therein or  necessary to
     make the statements therein not misleading);

        (v)  obtain  "cold  comfort"  letters  and  updates  thereof  from the
     independent  public  accountants  of the Company (and, if necessary,  any
     other independent  public accountants of any subsidiary of the Company or
     of any business  acquired by the Company for which  financial  statements
     and  financial  data are, or are  required  to be,  included in the Shelf
     Registration  Statement),  addressed  to each  such  Electing  Holder  of
     Registrable  Securities  registered  thereunder and the underwriters,  if
     any,  in  customary  form and  covering  matters of the type  customarily
     covered in "cold comfort" letters in connection with primary underwritten
     offerings;

        (vi) deliver such  documents  and  certificates  as may be  reasonably
     requested by any such Electing Holders and the Managing Underwriters,  if
     any,  including  those to evidence  compliance with Section 3(i) and with
     any customary conditions contained in the underwriting agreement or other
     agreement entered into by the Company.

     The foregoing  actions set forth in clauses (iii),  (iv), (v) and (vi) of
this Section 3(q) shall be  performed at each closing  under any  underwritten
offering to the extent required thereunder.

     (r) The Company  shall cause the Common Stock  issuable  upon  conversion
   thereof to be listed for  quotation on the NYSE or other stock  exchange or
   trading  system on which the Common Stock  primarily  trades on or prior to
   the effective


                                      13

<PAGE>

   date of any Shelf Registration Statement hereunder.

     (s) In the event that any broker-dealer registered under the Exchange Act
shall  underwrite any Registrable  Securities or participate as a member of an
underwriting  syndicate  or  selling  group or  "assist  in the  distribution"
(within  the  meaning of the  Conduct  Rules and the  By-Laws of the  National
Association  of Securities  Dealers,  Inc.  ("NASD"))  thereof,  whether as an
Electing  Holder  of  such  Registrable  Securities  or as an  underwriter,  a
placement  or  sales  agent or a broker  or  dealer  in  respect  thereof,  or
otherwise,  assist such  broker-dealer  in complying with the  requirements of
such Rules and By-Laws,  including,  without limitation,  by (A) such Rules or
By-Laws, including Schedule E thereto, shall so require, engaging a "qualified
independent  underwriter"  (as defined in Schedule  E) to  participate  in the
preparation of the Shelf  Registration  Statement relating to such Registrable
Securities  and to  exercise  usual  standards  of due  diligence  in  respect
thereto,  (B) indemnifying any such qualified  independent  underwriter to the
extent of the  indemnification  of under writers  provided in Section 5 hereof
and (C) providing such information to such broker-dealer as may be required in
order for such  broker-dealer  to comply with the requirements of the Rules of
Fair Practice of the NASD.

     (t) The  Company  shall  use its best  efforts  to take all  other  steps
necessary to effect the  registration,  offering  and sale of the  Registrable
Securities covered by the Shelf Registration Statement contemplated hereby.

     SECTION 4.  REGISTRATION  EXPENSES.  The Company  shall bear all fees and
expenses  incurred in connection with the performance of its obligations under
Sections 2 and 3 thereof and shall  reimburse  the Holders for the  reasonable
fees and  disbursements  of one firm of counsel  designated by the majority of
Holders to act as counsel for Holders in connection therewith.

     SECTION 5.  INDEMNIFICATION AND CONTRIBUTION.  (a) In connection with any
Shelf  Registration  Statement,  the Company shall indemnify and hold harmless
the Purchaser,  each Electing Holder,  each underwriter who participates in an
offering of Registrable  Securities,  each person, if any, who controls any of
such parties within the meaning of Section 15 of the Securities Act or Section
20 of the  Exchange  Act and each of  their  respective  directors, 


                                      14

<PAGE>

officers,  employees,  trustees and agents  (each such person being  sometimes
referred to as an "indemnified  party"),  from and against any and all losses,
claims,  damages or liabilities,  joint or several,  to which such indemnified
party may become  subject under the  Securities  Act or otherwise,  insofar as
such losses,  claims,  damages or liabilities (or actions in respect  thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in any Shelf  Registration  Statement under which
such Registrable  Securities are to be registered under the Securities Act, or
any  Prospectus   contained  therein  or  furnished  by  the  Company  to  any
indemnified party, or any amendment or supplement  thereto, or arise out of or
are based upon the  omission or alleged  omission to state  therein a material
fact required to be stated therein or necessary to make the statements therein
not  misleading,  and the Company hereby agrees to reimburse such  indemnified
party  for  any  legal  or  other  expenses  reasonably  incurred  by  them in
connection with investigating or defending or preparing to defend or appearing
as a third party  witness in  connection  with any such loss,  claim,  damage,
liability or action as such expenses are incurred; PROVIDED, HOWEVER, that the
Company shall not be liable in any such case to the extent that any such loss,
claim,  damage or liability arises out of or is based upon an untrue statement
or alleged untrue statement or omission or alleged omission made in such Shelf
Registration  Statement or Prospectus in reliance upon and in conformity  with
written  information  furnished  to the  Company  by  such  indemnified  party
expressly for use therein.

     (b) Each Electing Holder agrees,  severally and not jointly, to indemnify
and  hold  harmless  the  Company,   the  Purchaser,   each   underwriter  who
participates  in an offering of Registrable  Securities and the other Electing
Holders  and each of their  respective  directors,  officers  (including  each
officer  of  the  Company  who  signed  the  Shelf  Registration   Statement),
employees,  trustees  and agents and each  Person,  if any,  who  controls the
Company,  the Purchaser,  any under writer or any other Electing Holder within
the meaning of Section 15 of the  Securities Act or Section 20 of the Exchange
Act, from and against any and all loss,  liability,  claim, damage and expense
whatsoever  described in the  indemnity  contained in Section 5(a) hereof,  as
incurred, but only with respect to untrue statements or omissions,  or alleged
untrue statements or omissions,  made in the Shelf Registration  Statement (or
any  amendment  thereto) or any  Prospectus  (or any  amendment or  supplement
thereto) in reliance upon and in conformity with written information furnished
to the  Company  by  such  Electing  Holder  expressly  for  use in the  Shelf
Registration  Statement (or any amendment  thereto) or any


                                      15

<PAGE>

Prospectus (or any amendment or supplement thereto);  PROVIDED, HOWEVER, that,
no such Electing Holder shall be liable for any claims  hereunder in excess of
the amount of net proceeds  received by such Electing  Holder from the sale of
Registrable Securities pursuant to the Shelf Registration Statement.

     (c) In case any  action or  proceeding  (including  any  governmental  or
regulatory  investigation  or  proceeding)  shall be instituted  involving any
person in respect of which  indemnity may be sought  pursuant to either of the
two preceding  paragraphs,  such person  (hereinafter  called the  indemnified
party) shall  promptly  notify the person  against whom such  indemnity may be
sought (hereinafter called the indemnifying  party) in writing;  however,  the
omission to so notify the  indemnifying  party shall relieve the  indemnifying
party from liability only to the extent prejudiced  thereby.  The indemnifying
party,  upon  request of the  indemnified  party,  shall  assume  the  defense
thereof,  including the employment of counsel  reasonably  satisfactory to the
indemnified  party to represent the indemnified  party and any others that the
indemnifying  party may designate and shall pay the fees and  disbursements of
such counsel related to such proceeding.  In any such action or proceeding any
indemnified party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such indemnified party
unless  (i) the  indemnifying  party  and the  indemnified  party  shall  have
mutually  agreed to the retention of such counsel or (ii) the named parties to
any  such  proceeding  (including  any  impleaded  parties)  include  both the
indemnifying  party  and the  indemnified  party  and  representation  of both
parties by the same counsel would be inappropriate  due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in connection  with any  proceeding or related  proceedings  in the
same jurisdiction, be liable for the reasonable fees and expenses of more than
one  separate  firm (in  addition to any local  counsel)  for all  indemnified
parties and all persons,  if any, who control such indemnified  parties within
the meaning of either Section 15 of the Act or Section 20 of the Exchange Act.


                                      16

<PAGE>

     (d) If the indemnification provided for in this Section 5 is insufficient
or  unavailable  to an  indemnified  party in respect of any  losses,  claims,
damages or liabilities  (or actions in respect  thereof)  referred to therein,
then each indemnifying  party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified  party as a
result of such losses, claims,  damages,  liabilities and expenses (i) in such
proportion as is appropriate to reflect the relative  benefits received by the
indemnifying  party or  parties on the one hand and the  indemnified  party or
parties  on the  other  from the  offering  of the  Securities  or (ii) if the
allocation  provided by clause (i) above is not permitted by applicable law or
if  the  indemnified   party  shall  have  failed  to  the  prejudice  of  the
indemnifying  party to give the  notice  required  by  Section  5(c),  in such
proportion  as is  appropriate  to  reflect  not  only the  relative  benefits
referred  to  in  clause  (i)  above  but  also  the  relative  fault  of  the
indemnifying  party or  parties on the one hand and the  indemnified  party or
parties on the other in  connection  with the  statements  or omissions  which
resulted in such losses, claims, damages,  liabilities or expenses, as well as
any other relevant equitable considerations. The relative fault of the parties
shall be determined by reference to, among other things, whether the untrue or
alleged  untrue  statement  of a  material  fact or the  omission  or  alleged
omission  to state a material  fact  relates to  information  supplied  by the
Company,  on the one hand, or by the Electing Holder or such other indemnified
party, in the other hand, and the parties, relative intent, knowledge,  access
to  information  and  opportunity  to  correct or prevent  such  statement  or
omission.  The  Company,  the  Purchaser  and  the  Electing  Holders  of  the
Registrable  Securities  agree  that it  would  not be just and  equitable  if
contribution  pursuant  to this  Section 5 were to be  determined  by pro rata
allocation  or by any  other  method  of  allocation  that  does not take into
account the relevant  equitable  considerations.  For purposes of this Section
5(d), each director, officer, employee, trustee, agent and Person, if any, who
controls the Purchaser or an Electing  Holder within the meaning of Section 15
of the  Securities  Act or Section 20 of the  Exchange Act shall have the same
rights to  contribution  as the  Purchaser or such Electing  Holder,  and each
director,  officer,  employee,  trustee  and  agent of the  Company,  and each
Person,  if any, who controls the Company  within the meaning of Section 15 of
the  Securities  Act or  Section  20 of the  Exchange  Act shall have the same
rights to contribution


                                      17

<PAGE>

as the Company.  No party shall be liable for contribution with respect to any
action,  suit,  proceeding or claim settled  without its written  consent.  No
person guilty of fraudulent  misrepresentation  (within the meaning of Section
11(f) of the Act) shall be  entitled to  contribution  from any person who was
not guilty of such fraudulent misrepresentation.

     (e)  Notwithstanding  any other  provision of this Section 5, in no event
will any (i) Electing Holder be required to undertake  liability to any person
under this  Section 5 for any  amounts  in excess of the dollar  amount of the
proceeds  to be  received  by such  holder  from  the  sale  of such  holder's
Registrable  Securities  (after deducting any fees,  discounts and commissions
applicable  thereto) pursuant to any Shelf Registration  Statement under which
such Registrable  Securities are to be registered under the Securities Act and
(ii) underwriter,  selling agent or other securities  professional be required
to undertake  liability to any person  hereunder  for any amounts in excess of
the discount,  commission or other  compensation  payable to such underwriter,
selling agent or other securities professional with respect to the Registrable
Securities underwritten by it and distributed to the public.

     (f) The  obligations  of the  Company  under  this  Section 5 shall be in
addition  to any  liability  which the Company  may  otherwise  have and shall
extend, or not extend,  as the case may be, to any Indemnified  Person and the
obligations  of any  Indemnified  Person  under  this  Section  5 shall  be in
addition to any liability which such Indemnified Person may otherwise have and
shall extend, or not extend, as the case may be, to the Company.  The remedies
provided in this Section 5 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to an indemnified party at law or in
equity.

     SECTION 6.  UNDERWRITTEN  OFFERING.  The Electing  Holders of Registrable
Securities covered by the Shelf Registration Statement who desire to do so may
sell such  Registrable  Securities in an  underwritten  offering in accordance
with the conditions set forth below. In any such  underwritten  offering,  the
investment  banker or bankers and manager or managers that will administer the
offering will be selected by, and the underwriting  arrangements  with respect
thereto  will  be  approved  by the  Electing  Holders  of a  majority  of the
Registrable  Securities to be included in 


                                      18

<PAGE>

such  offering;  PROVIDED,  HOWEVER,  that (i) with respect to the  investment
bankers and managers, such investment bankers and managers will be selected by
the Company from a list of nationally  recognized  firms to be provided by the
Electing  Holders and (ii) the Company  shall not be  obligated to arrange for
more than two  underwritten  offering  during  the  Effectiveness  Period.  No
Electing  Holder may  participate in any  underwritten  offering  contemplated
hereby unless such Electing  Holder (a) agrees to sell such Electing  Holder's
Registrable   Securities   in  accordance   with  any  approved   underwriting
arrangements  and (b)  completes and executes all  reasonable  questionnaires,
powers of attorney, indemnities,  underwriting agreements, lock-up letters and
other  documents  required  under  the  terms  of such  approved  underwriting
arrangements.  Except as otherwise set forth herein,  the Electing  Holders of
Registrable  Securities  covered by the Shelf  Registration  Statement selling
under an underwritten  offering as contemplated  hereby will pay such expenses
as are  ordinarily  and  customarily  paid  in  connection  with  underwritten
secondary offerings.

     SECTION 7. MISCELLANEOUS. (a) OTHER REGISTRATION RIGHTS. From the date of
this Agreement,  the Company may grant  registration  rights that would permit
any  Person  that is a third  party  the  right  to  piggy-back  on any  Shelf
Registration Statement;  PROVIDED that if the Managing Underwriter, if any, of
such  offering  delivers  an opinion to the  Electing  Holders  that the total
amount of  securities  which they and the  holders of such  piggy-back  rights
intend  to  include  in any  Shelf  Registration  Statement  is so large as to
materially  adversely affect the success of such offering (including the price
at which such  securities  can be sold),  then only the amount,  the number or
kind of securities to be offered for the account of holders of such piggy-back
rights  granted after the date of this agreement will be reduced to the extent
necessary  to reduce the total  amount of  securities  to be  included in such
offering to the amount, number or kind recommended by the Managing Underwriter
prior to any reduction in the amount of Registrable Securities to be included.

     (b) AMENDMENTS AND WAIVERS. This Agreement,  including this Section 7(b),
may be amended,  and waivers or consents  to  departures  from the  provisions
hereof may be given,  only upon the written  consent of the  Purchaser or by a
written  instrument duly executed by the Company and the holders of a majority
in aggregate principal amount of


                                      19

<PAGE>

Registrable Securities then outstanding. Each holder of Registrable Securities
outstanding at the time of any such amendment, waiver or consent or thereafter
shall be bound by any amendment,  waiver or consent effected  pursuant to this
Section 7(b),  whether or not any notice,  writing or marking  indicating such
amendment,  waiver or consent  appears  on the  Registrable  Securities  or is
delivered to such holder.

     (c)  NOTICES.  All  notices  and  other  communications  provided  for or
permitted hereunder shall be given as provided in the Indenture.

     (d) PARTIES IN INTEREST.  The parties to this  Agreement  intend that all
holders of Registrable Securities shall be entitled to receive the benefits of
this  Agreement  and that any Electing  Holder shall be bound by the terms and
provisions  of this  Agreement by reason of such  election with respect to the
Registrable  Securities which are included in a Shelf Registration  Statement.
All the terms and  provisions of this Agreement  shall be binding upon,  shall
inure to the benefit of and shall be enforceable by the respective  successors
and  assigns of the  parties  hereto  and any holder  from time to time of the
Registrable  Securities  to the  aforesaid  extent.  In  the  event  that  any
transferee of any holder of Registrable  Securities shall acquire  Registrable
Securities,  in any manner, whether by gift, bequest,  purchase,  operation of
