maintain written standards that are reasonably designed to deter wrong-doing and
to promote:

1.    Honest and ethical conduct, including the ethical handling of actual or
      apparent conflicts of interest between personal and professional
      relationships;

2.    Full, fair, accurate, timely, and understandable disclosure in reports and
      documents that a registrant files with, or submits to, regulatory agencies
      and in other public communications made by the registrant;

3.    Compliance with applicable governmental laws, rules and regulations;

4.    The prompt internal reporting of violations of the standards to an
      appropriate person or persons identified in the standards; and

5.    Accountability for adherence to the standards.

      In addition the Company practices corporate governance in accordance with
rules and regulations in Canada.

      Corporate Governance relates to the activities of the Board of Directors
who are elected by and accountable to the Shareholders, and takes into account
the role of management who are appointed by the Board of Directors and who are
charged with the on-going management of the Company. The Board of Directors of
the Company encourages sound corporate governance practices designed to promote
the well being and on-going development of the Company, having always as its

a Corporate governance Committee has been established. The Corporate Governance
Committee meets with and discusses current disclosure issuances with our
management personnel, directors, and with both our Canadian and United States
counsel, in order to not only report to the Board of Directors any matters which
should be the subject of either public disclosure or remedial action but also to
assist the Board of Directors in establishing reporting and disclosure
procedures to ensure that we are in compliance with our disclosure and
compliance obligations under applicable laws, rules and obligations. Members of
the corporate governance committee are David Wilson and Barry Stansfield.EXHIBIT 10.1

                                 The Securities

            Section 2.01 Form and Dating. The Securities and the certificate of
authentication shall be substantially in the form of Exhibit A, which is hereby
incorporated in and expressly made a part of this Indenture. The Securities may
have notations, legends or endorsements required by Section 2.11, law, stock
exchange rule, automated quotation system, agreements to which the Company is
subject, or usage. Each Security shall be dated the date of its authentication.

            Section 2.02 Execution and Authentication. Two Officers shall sign
the Securities for the Company by manual or facsimile signature.

            If an Officer whose signature is on a Security no longer holds that
office at the time the Security is authenticated, the Security is still valid.

            A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

            The Trustee shall authenticate Securities for original issue up to
the amount stated in paragraph 4 of Exhibit A in accordance with an Officers'
Certificate of the Company. The aggregate principal amount of Securities
outstanding at any time may not exceed that amount except as provided in Section
2.07.

            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 rights as an Agent to deal with the Company or
an Affiliate.

            Section 2.03 Agents. The Company shall maintain an office or agency
where Securities may be presented for registration of transfer or for exchange
("Registrar"), where Securities may be presented for payment ("Paying Agent")
and where Securities may be presented for conversion to the extent and in the
manner set forth in Article 10 ("Conversion Agent"). Whenever the Company must
issue or deliver Securities pursuant to this Indenture, the Trustee shall
authenticate the Securities at the Company's request. The Registrar shall keep a
register of the Securities and of their transfer and exchange.

            The Company may appoint more than one Registrar, Paying Agent or
Conversion Agent. The Company shall notify the Trustee of the name and address
of any Agent not a party to this Indenture. If the Company does not appoint
another Registrar, Paying Agent, or Conversion Agent, the Trustee shall act as
such.

            Section 2.04 Paying Agent To Hold Money in Trust. On or prior to
each due date of the Principal and interest on any Security, the Company shall
deposit with the Paying Agent a sum sufficient to pay such Principal and
interest when so becoming due. The Company

                                      -4-
<PAGE>

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 the Principal
of 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 and to account for any funds disbursed by the Paying Agent. Upon
complying with this Section, the Paying Agent shall have no further liability
for the money delivered to the Trustee. If the Company or any Affiliate acts as
Paying Agent, it shall segregate the money held by it as Paying Agent and hold
it as a separate trust fund.

            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, in writing at least 10
Business Days before each interest payment date and at such other times as the
Trustee may request 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. The Securities shall be issued
in registered form and shall be transferable only upon surrender of a Security
for registration of transfer. When a Security is presented to the Registrar with
a request to register a transfer or to exchange them for an equal principal
amount of Securities of other denominations, the Registrar shall register the
transfer or make the exchange if its requirements for such transactions are met
and the Security has not been redeemed. The Company may charge a reasonable fee
for any registration of transfer or exchange but not for any exchange pursuant
to Section 2.10, 3.06 or 9.05.

            All Securities issued upon any transfer or exchange pursuant to the
terms of this Indenture will evidence the same debt and will be entitled to the
same benefits under this Indenture as the Securities surrendered upon such
transfer or exchange.

            Section 2.07 Replacement Securities. If the Holder of a Security
claims that the Security has been lost, destroyed or wrongfully taken, then, in
the absence of notice to the Company that the Security has been acquired by a
protected purchaser, the Company shall issue a replacement Security. If required
by the Trustee or the Company, an indemnity bond must be provided which is
sufficient in the judgment of both to protect the Company, the Trustee and the
Agents from any loss which any of them may suffer if a Security is replaced. The
Company or the Trustee may charge the Holder for its expenses in replacing a
Security.

            Every replacement Security is an additional obligation of the
Company.

            Section 2.08 Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by the Registrar, those delivered to it for cancellation and those described in
this Section as not outstanding. A Security does not cease to be outstanding
because the Company or an Affiliate holds the Security.

                                      -5-
<PAGE>

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

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

            Section 2.09 Treasury Securities Disregarded for Certain Purposes.
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 shall be disregarded and deemed not to be
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 the Trustee knows are so owned shall be so disregarded.
Securities so owned which have been pledged in good faith shall not be
disregarded if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right to deliver any such direction, waiver or consent with respect to
the Securities and that the pledgee is not the Company or any other obligor upon
the Securities or any Affiliate of the Company or of such other obligor.

            Section 2.10 Temporary Securities. Until definitive Securities are
ready for delivery, the Company may use temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall deliver definitive Securities in
exchange for temporary Securities.

            Section 2.11 Global Securities. The Company may issue some or all of
the Securities in temporary or permanent global form. The Company may issue a
global Security only to a depository. A depository may transfer a global
Security only to its nominee or to a successor depository. A global Security
shall represent the amount of Securities specified in the global Security. A
global Security may have variations that the depository requires or that the
Company considers appropriate for such a security.

            Beneficial owners of part or all of a global Security are subject to
the rules of the depository as in effect from time to time.

            The Company, the Trustee and the Agents shall not be responsible for
any acts or omissions of a depository, for any depository records of beneficial
ownership interests or for any transactions between the depository and
beneficial owners.

            Section 2.12 Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Paying Agent and Conversion
Agent, if not the Trustee, shall forward to the Trustee any Securities
surrendered to them for payment or conversion. The Trustee shall cancel all
Securities surrendered for registration of transfer, exchange, payment,
conversion or cancellation and shall dispose of canceled Securities according to
its standard procedures or as the Company otherwise directs. The Company may not
issue new Securities to replace Securities that it has paid or which have been
delivered to the Trustee for cancellation or that any Securityholder has
converted.

            Section 2.13 Defaulted Interest. If the Company defaults in a
payment of interest on the Securities ("Defaulted Interest") such Defaulted
Interest shall cease to be payable to the Securityholder on the relevant record
date and shall be paid by the Company, at its election, under either (1) or (2)
below:

            (1) The Company may pay the Defaulted Interest together with
      interest thereon to the Persons which are Securityholders on a subsequent
      special record date. The Company shall notify the Trustee of the amount of
      Defaulted Interest together with interest thereon to be paid and pay over
      such amount to the Trustee. The Trustee shall then fix a special record
      date and at the Company's expense shall notify Securityholders not less
      than 10 days prior to such special record date of the proposed payment, of
      the special record date, and of the payment date.

            (2) The Company may make payment of Defaulted Interest together with
      interest thereon in any lawful manner not inconsistent with the
      requirements of any securities exchange or automated quotation system on
      which the Securities may be listed or designated for issuance. The Company
      shall give prompt notice to the Trustee and Securityholders that it
      intends to make payment pursuant to this Section 2.13(2) and of the
      special record date of the proposed payment, and of the payment date.

                                   ARTICLE 3

                                   Redemption

            Section 3.01 Notice to Trustee. If Securities are to be redeemed,
the Company shall notify the Trustee of the redemption date, the Principal
amount of Securities to be redeemed and the provision of the Securities
permitting or requiring the redemption.

            The Company may reduce the Principal amount of Securities required
to be redeemed pursuant to Paragraph Six of the Securities if it notifies the
Trustee of the amount of the credit and the basis for it by delivery of an
Officers' Certificate. If the reduction is based on a credit for redeemed,
converted or canceled Securities that the Company has not previously delivered
to the Trustee for cancellation, the Company shall deliver such Securities to
the Registrar before the selection of securities to be redeemed.

            The Company shall give each notice provided for in this Section at
least 50 days before the redemption date unless a shorter period is satisfactory
to the Trustee. If fewer than all the Securities are to be redeemed, the record
date relating to such redemption shall be selected by the Company and given to
the Trustee, which record date shall be not less than 15 days prior to the
redemption date.

            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 a method that complies with the requirements, if any, of any
stock exchange on which the Securities are listed and that the Trustee considers
fair and appropriate, which may include selection pro rata or by lot. The
Trustee shall make the selection from Securities outstanding not previously
called for redemption. The Trustee may select for redemption portions of the
Principal of Securities

                                      -7-
<PAGE>

that have denominations larger than $1,000. Securities and portions thereof
selected by the Trustee shall be in amounts of $1,000 or whole multiples of
$1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities 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.

            The notice shall state that it is a notice of redemption, identify
the Securities to be redeemed and shall state:

            (1) the redemption date;

            (2) the redemption price;

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

            (4) that Securities called for redemption must be surrendered to the
      Paying Agent to collect the redemption price;

            (5) that, unless the Company defaults in making such redemption
      payment or the Paying Agent is prohibited from making such payment
      pursuant to the terms of this Indenture, interest on Securities (or
      portion thereof) called for redemption ceases to accrue on and after the
      redemption date; and

            (6) list the CUSIP number of the Securities and state that no
      representation is made as to the correctness or accuracy of the CUSIP
      number, if any, listed in such notice or printed on the Securities.

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

            Section 3.04 Effect of Notice of Redemption. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date at the redemption price. Upon surrender to the Paying Agent,
such Securities shall be paid at the redemption price stated in the notice, plus
accrued interest to the redemption date. Failure to give notice or any defect in
the notice to any Holder shall not affect the validity of the notice to any
other Holder.

            Section 3.05 Deposit of Redemption Price. On or before the
redemption date, the Company shall deposit with the Paying Agent (or, if the
Company or any Affiliate is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the redemption price of, and accrued interest on, all
Securities to be redeemed on that date other than Securities or portions of
Securities called for redemption which have been delivered by the Company to the
Registrar for cancellation. The Paying Agent shall return to the Company any
money not required for that purpose because of conversion of Securities.

                                      -8-
<PAGE>

            Unless the Company shall default in the payment of Securities (and
accrued interest) called for redemption, interest on such Securities shall cease
to accrue after the redemption date.

            Section 3.06 Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall deliver to the Holder (at
the Company's expense) a new Security equal in Principal amount to the
unredeemed portion of the Security surrendered.

                                   ARTICLE 4

                                    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 and this Indenture. Principal and interest shall be
considered paid on the date due if the Paying Agent holds in accordance with
this Indenture on that date money sufficient to pay all Principal and interest
then due and the Paying Agent is not prohibited from paying such money to the
Holders on such date pursuant to the terms of this Indenture.

            The Company shall pay interest on overdue Principal at the rate
borne by the Securities; it shall pay interest on overdue Defaulted Interest at
the same rate to the extent lawful.

            Section 4.02 SEC Reports. The Company shall file with the Trustee
within 15 days after it files them with the SEC copies of the annual reports and
of the information, documents, and other reports which the Company is required
to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The
Company will cause any quarterly and annual reports which it makes available to
its stockholders to be mailed to the Holders. The Company will also comply with
the other provisions of TIA ss. 314(a). Delivery of such reports, information
and documents to the Trustee is for informational purposes only and the
Trustee's receipt of such shall not constitute notice or constructive notice of
any information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

            Section 4.03 Compliance Certificate. The Company shall deliver to
the Trustee, within [105] days after the end of each fiscal year of the Company,
a brief certificate signed by the principal executive officer, principal
financial officer or principal accounting officer of the Company, as to the
signer's knowledge of the Company's compliance with all conditions and covenants
contained in this Indenture (determined without regard to any period of grace or
requirement of notice provided herein).

            Section 4.04 Notice of Certain Events. The Company shall give prompt
written notice to the Trustee and any Paying Agent of (i) any Proceeding, (it)
any Default or Event of Default, (iii) any cure or waiver of any Default or
Event of Default, and (iv) if and when the Securities are listed on any stock
exchange.

                                   Successors

            Section 5.01 When Company May Merge, etc. The Company shall not
consolidate or merge with or into, or transfer all or substantially all of its
assets to, any Person unless:

            (1) either the Company shall be the resulting or surviving entity or
      such person is a corporation organized and existing under the laws of the
      United States, a State thereof or the District of Columbia;

            (2) if the Company is not the resulting or surviving entity, such
      Person assumes by supplemental indenture all the obligations of the
      Company under the Securities and this Indenture; and

            (3) immediately before and immediately after the transaction no
      Default exists.

            The Company shall deliver to the Trustee prior to the proposed
transaction an Officers' Certificate and an Opinion of Counsel, each of which
shall state that such consolidation, merger or transfer and such supplemental
indenture comply with this Article 5 and that all conditions precedent herein
provided for relating to such transaction have been complied with.

            Section 5.02 Successor Corporation Substituted. Upon any
consolidation or merger, or any transfer of all or substantially all of the
assets of the Company in accordance with Section 5.01, the successor corporation
formed by such consolidation or into which the Company is merged or to which
such transfer is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under this Indenture and the Securities
with the same effect as if such successor corporation had been named as the
Company herein and in the Securities. Thereafter the obligations of the Company
under the Securities and Indenture shall terminate except for the obligation to
pay the Principal of and interest on the securities in the case of a transfer.

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

            (3) the Company fails to comply with any of its other agreements in
      the Securities or this Indenture and such failure continues for the period
      and after the notice specified below;

            (4) the Company pursuant to or within the meaning of any Bankruptcy
      Law:

                  (A) commences a voluntary case,

                  (B) consents to the entry of an order for relief against it in
            an involuntary case,

                  (C) consents to the appointment of a Custodian of it or for
            all or substantially all of its property, or

                  (D) makes a general assignment for the benefit of its
            creditors; or

            (5) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that:

                  (A) is for relief against the Company in an involuntary case,

                  (B) appoints a Custodian of the Company or for all or
            substantially all of its property, or

                  (C) orders the liquidation of the Company, and the order or
            decree remains unstayed and in effect for 60 days.

            The foregoing will constitute Events of Default whatever the reason
for any such Event of Default, whether it is voluntary or involuntary, or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

            The term "Bankruptcy Law" means title 11, U.S. Code or any similar
Federal or state law for the relief of debtors. The term "Custodian" means any
receiver, trustee, assignee, liquidator or similar official under any Bankruptcy
Law.

            A Default under clause (3) is not an Event of Default until the
Trustee or the Holders of at least 25% in Principal amount of the Securities
notify the Company and the Trustee of the Default and the Company does not cure
the Default, or it is not waived, within [60] days after receipt of the notice.
The notice must specify the Default, demand that it be remedied to the extent
consistent with law, and state that the notice is a "Notice of Default".

            Section 6.02 Acceleration. If an Event of Default occurs and is
continuing, the Trustee by notice to the Company, or the Holders of at least 25%
in Principal amount of the Securities by notice to the Company and the Trustee,
may declare the 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.

                                      -11-
<PAGE>

            The Holders of a majority in Principal amount of the Securities by
notice to the Company and 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 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. The Holders of a majority in
Principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except:

            (1) a Default in the payment of the Principal of or interest on any
      Security; or

            (2) a Default with respect to a provision that under Section 9.02
      cannot be amended without the consent of each Securityholder affected; or

            Section 6.05 Control by Majority. The Holders of a majority in
Principal amount of the 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 the Trustee. 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 or expense for which the Trustee has not received a
satisfactory indemnity therefor.

            Section 6.06 Limitation on Suits. A Securityholder may pursue a
remedy with respect to this Indenture or the Securities only if:

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

            (2) the Holders of at least 25% in Principal amount of the
      Securities make a request to the Trustee to pursue the remedy;

            (3) the Trustee either (i) gives to such Holders notice it will not
      comply with the request, or (ii) does not comply with the request within
      [15 or 30] days after receipt of the request; and

            (4) the Holders of a majority in Principal amount of the Securities
      do not give the Trustee a direction inconsistent with the request prior to
      the earlier of the date, if ever,

                                      -12-
<PAGE>

      on which the Trustee delivers a notice under Section 6.06(3)(i) or the
      expiration of the period described in Section 6.06(3)(ii).

            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.

            Nothing in this Indenture limits or defers the right or ability of
Holders to petition for commencement of a case under applicable Bankruptcy Law
to the extent consistent with such Bankruptcy Law.

            Section 6.08 Priorities. After an Event of Default any money or
other property distributable in respect of the Company's obligations under this
Indenture shall be paid in the following order:

            First: to the Trustee (including any predecessor Trustee) for
      amounts due under Section 7.07;

            Second: 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

            Third: to the Company.

            The Trustee may fix a record date and payment date for any payment
to Securityholders.

            Section 6.09 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 Trustee, a court in its discretion may
require the filing by any party 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 Securities.

            Section 6.10 Proof of Claim. In the event of any Proceeding, the
Trustee may file a claim for the unpaid balance of the Securities in the form
required in the Proceeding and cause the claim to be approved or allowed.
Nothing herein contained 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 Proceeding.

            Section 6.11 Actions of a Holder. For the purpose of providing any
consent, waiver or instruction to the Company or the Trustee, a "Holder" or
"Securityholder" shall include a Person who provides to the Company or the
Trustee, as the case may be, an affidavit of beneficial ownership of a Security
together with a satisfactory indemnity against any loss, liability or expense to
such party to the extent that it acts upon such affidavit of beneficial
ownership (including any consent, waiver or instructions given by a Person
providing such affidavit and indemnity).

                                   ARTICLE 7

                                     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 person would exercise or use under the
circumstances in the conduct of its own affairs.

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

            (1) The Trustee need perform only those duties that are specifically
      set forth in this Indenture and no others.

            (2) 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.

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

            (1) This paragraph does not limit the effect of paragraph (b) of
      this Section.

            (2) 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.

            (3) The Trustee shall not be liable with respect 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.

            (4) The Trustee may refuse to perform any duty or exercise any right
      or power which would require it to expend its own funds or risk any
      liability if it shall reasonably believe that repayment of such funds or
      adequate indemnity against such risk is not reasonably assured to it.

                                      -14-
<PAGE>

            (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 shall not be liable for interest on any money
received by it except as the Trustee may agree 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. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on the
Officers' Certificate or an Opinion of Counsel. The Trustee may also consult
with counsel on any matter relating to the Indenture or the Securities and the
Trustee shall not be liable for any action it takes or omits to take in good
faith in reliance on the advice of counsel.

            (c) The Trustee may act through agents and shall not be responsible
for the misconduct or negligence of any agent 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.

            (e) Except in connection with compliance with TIA ss. 310 or ss.
311, the Trustee shall only be charged with knowledge of Trust Officers.

            Section 7.03 Individual Rights of Trustee; Disqualification. 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 TIA ss. 310(b) and ss. 311.

            Section 7.04 Trustee's Disclaimer. The Trustee shall have no
responsibility for 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 in the Securities
other than its authentication.

            Section 7.05 Notice of Defaults. If a continuing Default is known to
the Trustee, the Trustee shall mail to Securityholders a notice of the Default
within 90 days after it occurs. Except in the case of a Default in payment on
any Security, 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. [The Trustee shall mail to Securityholders any
notice it receives from Securityholder(s) under Section 6.06, and of any notice
the Trustee provides pursuant to Section 6.06(3)( 1).]

            Section 7.06 Reports by Trustee to Holders. If required pursuant to
TIA ss. 313(a), within 60 days after the reporting date stated in Section 12.09,
the Trustee shall mail to

                                      -15-
<PAGE>

Securityholders 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).

            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.

            Section 7.07 Compensation and Indemnity. The Company shall pay to
the Trustee from time to time reasonable compensation for its services,
including for any Agent capacity in which it acts. 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 shall include the
reasonable compensation and out-of-pocket expenses of the Trustee's agents and
counsel.

            The Company shall indemnify the Trustee against any loss, liability
or expense incurred by it including in any Agent capacity in which it acts. 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 unreasonably be
withheld.

            The Company need not reimburse any expense or indemnify against any
loss or liability incurred by the Trustee through gross negligence, wilful
misconduct 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, except that held in trust to pay Principal and
interest on particular Securities.

            Without prejudice to its rights hereunder, when the Trustee incurs
expenses or renders services after an Event of Default specified in Section
6.01(4) or (5) occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any Bankruptcy 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 Securities may remove the Trustee by so
notifying the Trustee and the Company. The Company may remove the Trustee if:

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

            (2)   the Trustee is adjudged a bankrupt or an insolvent;

            (3)   a receiver or public officer takes charge of the Trustee or
                  its property; or

            (4)   the Trustee becomes incapable of acting.

                                      -16-
<PAGE>

            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.

            If a successor Trustee is not appointed and does not take office
within 30 days after the retiring Trustee resigns, the retiring Trustee may
appoint a successor Trustee at any time prior to the date on which a successor
Trustee takes office. If a successor Trustee does not take office within [45]
days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or, subject to Section 6.09, any Securityholder 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
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee. Within one year after a successor
Trustee appointed by the Company or a court pursuant to this Section 7.08 takes
office, the Holders of a majority in Principal amount of the Securities may
appoint a successor Trustee to replace such 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.

            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, if such successor
corporation is eligible and qualified under Section 7.10.

            Section 7.10 Eligibility. This Indenture shall always have a Trustee
who satisfies the requirements of TIA ss. 310(a)(1) and ss. 310(a)(2). The
Trustee shall always have a combined capital and surplus as stated in Section
12.09.

            Section 7.11 Preferential Collection of Claims Against Company. Upon
and so long as the Indenture is qualified under the TIA, 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 is subject to TIA ss. 311(a) to the
extent indicated.

            Section 8.01 Satisfaction and Discharge of Indenture. This Indenture
shall cease to be of further effect (except as to any surviving rights of

provided for herein), and the Trustee, on demand of and at expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

            (1) either

                  (A) all Securities theretofore authenticated and delivered
            (other than (i) Securities which have been destroyed, lost or stolen
            and which have been replaced or paid as provided in Section 2.07 and
            (ii) Securities for whose payment money has theretofore been
            deposited in trust or segregated and held in trust by the Company
            and thereafter repaid to the Company or discharged from such trust,
            as provided in Section 8.04) have been delivered to the Trustee for
            cancellation; or

                  (B) all such Securities not theretofore delivered to the
            Trustee for cancellation

                        (i) have become due and payable, or

                        (ii) will become due and payable at their stated
                  maturity within one year, or

                        (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company,

                  and the Company in the case of (i), (ii), and (iii) above, has
                  deposited or caused to be deposited with the Trustee as trust
                  funds in trust for the purpose an amount of money or U.S.
                  Government Obligations sufficient to pay and discharge the
                  entire indebtedness on such Securities not theretofore
                  delivered to the Trustee for cancellation, for Principal and
                  interest to the date of such deposit (in the case of
                  Securities which have become due and payable) or to the stated
                  maturity or redemption date, as the case may be;

            (2) the Company has paid or caused to be paid all other sums payable
      hereunder by the Company; and

            (3) the Company has delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent herein provided for relating to the satisfaction and discharge
      of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Holders under Section 4.01, to the Trustee
under Section 7.07, and, if money or U.S. Government Obligations shall have been
deposited with the Trustee pursuant to subclause (B) of Clause (1) of this
Section, the obligations of the Trustee under Section 8.02 shall survive.

Section 8.02 Application of Trust Funds. The Trustee or Paying Agent shall hold
in trust, for the benefit of the Holders, all money and U.S. Government
Obligations deposited with it (or into which such money and U.S. Government
Obligations are reinvested) pursuant to Section 8.01. It shall apply such
deposited money and money from U.S. Government

                                      -18-
<PAGE>

and interest on the Securities. Money and U.S. Government Obligations so held in
trust are subject to the Trustee's rights under Section 7.07.

            Section 8.03 Reinstatement. If the Trustee or Paying Agent is unable
to apply any money or U.S. Obligations in accordance with Section 8.01 by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the Company's
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to this Article 8, until
such time as the Trustee or Paying Agent is permitted to apply all such money or
U.S. Government Obligations in accordance with Section 8.01; provided, however,
that if the Company makes any payment of Principal of or interest on 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 or U.S. Government Obligations held by the Trustee or
Paying Agent after payment in full to the Holders.

            Section 8.04 Repayment to Company. The Trustee and Paying Agent
shall promptly turn over to the Company upon request any excess money or U.S.
Government Obligations held by them at any time. All money or U.S. Government

or a Paying Agent) for the payment of Securities subsequently converted shall be
returned to the Company upon request.

            The Trustee and the Paying Agent shall pay to the Company upon
request any money held by them for payment of Principal or interest that remains
unclaimed for two years after the right to such money has matured. After payment
to the Company, Securityholders entitled to the money shall look to the Company
for payment as unsecured general creditors unless an abandoned property law
designates another Person.

Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent approves the substance thereof.

            Section 9.03 Compliance with Trust Indenture Act and Section 12.03.

supplemental indenture is permitted under this Article 9.

            Section 9.04 Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or Waiver as to such Holder's
