                                   ARTICLE II
                                 THE SECURITIES

      Section 2.1 Security Terms; Amount; Accounts; Interest; Maturity.

            (a) Unlimited Amount and Form of Security. The outstanding aggregate
      principal amount of Securities outstanding at any time is limited to $50
      million, provided, however, that the Company and the Trustee may, without
      the consent of any Holder, increase such aggregate principal amount of
      Securities which may be outstanding at any time. The Securities are
      unsecured obligations of the Company and shall be subordinate in right of
      payment to the Senior Debt of the Company as further described in Article
      X. The Securities are an obligation and liability of the Company, and not
      of any other Person, including without limitation any Affiliate or Agent
      of the Company. The Securities are not certificates of deposit or similar
      obligations of, and are not guaranteed or insured by, any depository
      institution, the Federal Deposit Insurance Corporation, any other
      governmental or private fund, any securities insurer or any other Person.

            The Securities, together with the Trustee's certificate of
      authentication, shall be in substantially the form set forth as Exhibit A
      to this Indenture, with any appropriate insertions, omissions,
      substitutions and other variations as are required or permitted by this
      Indenture and may have such letters, numbers or other marks of
      identification and such legends or endorsements placed thereon as may be
      required to comply with the rules of any securities exchange or as may,
      consistently herewith, be determined by the officers executing such
      Securities, as evidenced by their execution of the Securities. Any portion
      of the text of any Securities may be set forth on the reverse thereof,
      with an appropriate reference thereto on the face of the Securities. The
      Securities may be subject to notations, legends or endorsements required
      by law, stock exchange rule, or agreements to which the Company is subject
      or usage.

            (b) Book-Entry; Denominations; Term. Except as provided in Section
      2.14(b), each Security shall neither be issued as, nor evidenced by, a
      promissory note or certificated security, but rather each Security shall
      be issued in book entry or uncertificated form, in which the record of
      beneficial ownership of each such Security shall be established and
      maintained as Accounts by the Registrar pursuant to Section 2.14. In
      connection with the issuance of each Security in book entry form in
      accordance with Section 2.14, each such Security shall be deemed to be
      represented in an uncertificated form that includes the same terms and
      provisions as those set forth in the form of Security in Exhibit A to this
      Indenture, and the related Account for each such Security shall be deemed
      to include these same terms and provisions.

            Each Security shall be in such denominations as may be designated
      from time to time by the Company, but in no event in an original
      denomination less than $1,000. Separate purchases may not be cumulated to
      satisfy the minimum denomination requirements. Each Security shall have a
      term of not less than three months and not greater than 120 months as
      shall be designated by the Holder at the time of purchase, subject to the
      Company's acceptance thereof.

INDENTURE - Page 7
<PAGE>
            (c) Interest and Interest Payments. Each Security shall bear
      interest from and commencing on its Issue Date at such rate of interest as
      the Company shall determine from time to time, which rate may vary from
      Holder to Holder depending upon the aggregate principal amount of
      Securities held by such Holder and any immediate family member, as set
      forth in the Prospectus; provided, however, that the interest rate of each
      Security will be fixed for the term of such Security upon issuance,
      subject to change upon the renewal of the Security at maturity. Interest
      on the Securities will compound daily and the Holder thereof may elect to
      have interest paid monthly, quarterly, semi-annually, annually, or upon
      maturity, which payments shall be made on the Payment Date, except that a
      Holder who elects monthly payments may select the day of the month on
      which to receive interest payments, subject to the Company's approval;
      provided that no interest shall be paid to a Holder until the expiration
      of the Holder's rescission right under Section 2.2(b). A Holder may change
      this election once during the term of the Security, subject to the
      Company's approval, which change shall be effective the first Business Day
      following the forty-fifth (45th) day after receipt of written notice from
      the Holder requesting such change.

            (d) Repayment Election at Maturity. The Company will send each
      Holder of a Security (existing as of the applicable Maturity Record Date)
      a Notice of Maturity approximately fifteen (15) but not less than ten (10)
      days prior to the Maturity Date of the Security held by such Holder
      reminding such Holder of the pending maturity of the Security and
      reminding the Holder that the automatic renewal provision described in the
      next paragraph will take effect, unless (i) the Company states in the
      Notice of Maturity that it will not allow the Holder to renew the Security
      (in which case the Company shall pay the Holder principal and accrued
      interest with regard to the Security on the Maturity Date), or (ii) the
      Holder delivers a Repayment Election to the Company for the payment of all
      principal and interest due on the Security as of the Maturity Date so that
      such Repayment Election is received by the Company within fifteen (15)
      days after the Maturity Date. Such Notice of Maturity shall also state
      that payment of principal of a Security shall be made upon presentation of
      a Repayment Election requiring payment of such Security and shall specify
      the place where such Repayment Election may be presented. Upon or
      following the delivery of a Notice of Maturity for a Security, the Holder
      thereof, in their discretion, may deliver to the Company a Repayment
      Election; provided that such Repayment Election must be delivered to the
      Company no later than fifteen (15) days after the Maturity Date. If a
      Holder delivers a Repayment Election requiring repayment within fifteen
      (15) days after the Maturity Date, no interest will accrue after the
      Maturity Date and the Holder will be sent payment upon the later of the
      Maturity Date or five (5) days following the date the Company receives
      such Repayment Election from the Holder; provided that any interest paid
      to the Holder accruing after the Maturity Date shall be deducted from such
      payment.

            The Notice of Maturity also shall state that the Holder may, and the
      Holder may, submit a Repayment Election for the repayment of the maturing
      Security and use all or a portion of the proceeds thereof to purchase a
      new Security with a different term. To exercise this option, the Holder
      shall complete a new Subscription Agreement for the new Security and send
      it along with the Holder's Repayment Election to the Company. The Issue
      Date of the new Security shall be the Maturity Date of the maturing
      Security. Any

INDENTURE - Page 8
<PAGE>
      proceeds from the maturing Security that are not applied to the purchase
      of the new Security shall be sent to the Holder of such maturing Security.

            If a Security pays interest only on the Maturity Date, then the
      Notice of Maturity also shall state that the Holder may, and the Holder
      may, submit an "interest-only" Repayment Election in which the Holder
      requires the payment of the accrued interest that such Holder has earned
      on the maturing Security up to the Maturity Date and allows the principal
      amount of such maturing Security to renew in the manner provided in
      subsection (e) below.

            (e) Automatic Renewal. If, within fifteen (15) days after the
      Maturity Date of a Security, a Holder of such Security has not delivered a
      Repayment Election for repayment of the Security, and the Company did not
      notify the Holder of its intention to repay the Security in the Notice of
      Maturity, then such maturing Security shall be extended automatically for
      an additional term equal to the original term, and shall be deemed to be
      renewed by the Holder and the Company as of the Maturity Date of such
      maturing Security, such that a new Security shall be deemed to have been
      issued as of such Maturity Date. A maturing Security will continue to
      renew as described herein absent a Redemption Notice or Repurchase Request
      by the Holder or an indication by the Company that it will repay and not
      allow the Security to be renewed in the Notice of Maturity. Interest on
      the renewed Security shall accrue from the Issue Date thereof, which is
      the first day of such renewed term (i.e., the Maturity Date of the
      maturing Security). Such renewed Security will be deemed to have the
      identical terms and provisions of the maturing Security, including
      provisions relating to payment, except that the interest rate payable
      during the term of the renewed Security shall be the interest rate which
      is being offered by the Company on other Securities having the same term
      as of the Issue Date of such renewal. If other Securities having the same
      term are not then being issued on the Issue Date of such renewal, the
      interest rate upon renewal will be the rate specified by the Company on or
      before the Maturity Date of such Security, or the then existing rate of
      the Security being renewed if no such rate is specified. If the maturing
      Security pays interest only on the Maturity Date, then, except as provided
      in subsection (d) above, all accrued interest thereon shall be added to
      the principal amount of the renewed Security upon renewal. If such
      maturing Security has a different interest payment option, then interest
      will be paid on the renewed Security in the same manner as the maturing
      Security.

            (f) Redemption Notice from Company. Pursuant to Section 3.1, each
      Security shall be redeemable by the Company at any time, without penalty,
      upon the delivery of a Redemption Notice to the Holder of such Security.
      Such Redemption Notice shall set forth a date for the redemption of such
      Security (the "Redemption Date") that is at least thirty (30) days after
      the date that such Redemption Notice has been delivered by the Company to
      the Holder hereunder.

            (g) Repurchase Request by Holder. Pursuant to and subject to the
      limitations set forth in Section 3.2, each Security shall be subject to
      repurchase at the request of the Holder upon the delivery of a Repurchase
      Request to the Company. The payment of interest and principal due upon the
      repurchase of a Security shall be made to the Holder

INDENTURE - Page 9
<PAGE>
      on a Repurchase Date that is within ten (10) days of the delivery of such
      Repurchase Request to the Company, subject to the limitations on
      repurchase and the Repurchase Penalties described in Section 3.2.

            (h) Terms of Securities. The terms and provisions contained in the
      Securities shall constitute, and are hereby expressly made, a part of this
      Indenture and to the extent applicable, the Company and the Trustee, by
      their execution and delivery of this Indenture, and the Holders by
      accepting the Securities, expressly agree to such terms and provisions and
      to be bound hereby and thereby. In case of a conflict, the provisions of
      the Securities shall control.

      Section 2.2 Written Confirmation; Rejection; Rescission.

            (a) Except with respect to an automatically renewed Security
      pursuant to Section 2.1(e), a Security shall not be validly issued to a
      Person until the following have occurred: (i) such Person has remitted
      good and available funds for the full principal amount of such Security to
      the Company; (ii) a Written Confirmation of the acceptance of the
      subscription is sent by the Company or a duly authorized Agent of the
      Company to such Person; and (iii) an Account is established by the
      Registrar in the name of such Person as the Holder of such Security
      pursuant to Section 2.14 hereof. The Company or a duly authorized Agent of
      the Company, in their sole discretion, may reject any subscription from a
      Person for the purchase of Securities, in which event any funds received
      from such Person pursuant to such subscription shall be promptly returned
      to such Person. No interest shall be paid on any funds returned on a
      rejected subscription.

            (b) For a period of three (3) Business Days following the receipt by
      the Holder of a Written Confirmation that evidences the valid issuance of
      a Security at the time of original purchase (but not upon transfer or
      automatic renewal of a Security), such Holder shall have the right to
      rescind the Security and receive repayment of the principal by presenting
      a written request to the Company. Repayment of the principal shall be made
      within ten (10) days of the Company's receipt of such request from the
      Holder. No interest shall be paid on any such rescinded Security.

      Section 2.3 Registrar and Paying Agent.

            (a) The Company shall maintain (i) an office or agency where
      Securities may be presented for registration of transfer or for exchange
      ("Registrar") and (ii) an office or agency where Securities may be
      presented for payment ("Paying Agent"). The Registrar shall keep a
      register of the Securities and of their transfer and exchange, which shall
      include the name, address for notices and Payment Account of the Holder
      and the payment election information, principal amount, term and interest
      rate for each Security (the "Securities Register"). The Company may
      appoint one or more co-registrars and one or more additional paying
      agents. The term "Registrar" includes any co-registrar, and the term
      "Paying Agent" includes any additional paying agent. The Company may
      change any Paying Agent or Registrar without prior notice to any Holder;
      provided that the Company shall promptly notify the Holders of the name
      and address of any Agent not a party to this Indenture. The Company may
      act as Paying Agent and/or Registrar. In the

INDENTURE - Page 10
<PAGE>
      event the Company uses any Agent other than the Company or the Trustee,
      the Company shall enter into an appropriate agency agreement with such
      Agent, which agreement shall incorporate the provisions of the TIA or
      provide that the duties performed thereunder are subject to and governed
      by the provisions of this Indenture. The agreement shall implement or be
      subject to the provisions of this Indenture that relate to such Agent. The
      Company shall notify the Trustee of the name and address of any such
      Agent. If the Company fails to maintain a Registrar or Paying Agent, or
      fails to give the foregoing notice, the Trustee shall act as such, and
      shall be entitled to appropriate compensation in accordance with Section
      7.7 hereof.

            (b) The Company shall appoint a servicing agent as the initial
      Registrar pursuant to Section 2.16. _____________ shall be appointed as
      the initial Paying Agent. The Company initially appoints the Trustee as
      agent for service of notices and demands in connection with the
      Securities. Such servicing agent shall act as Registrar and _____________
      shall act as Paying Agent, until such time as the Company gives the
      Trustee written notice to the contrary.

      Section 2.4 Paying Agent to Hold Money in Trust.

      Prior to each due date of the principal or interest on any Security, the
Company shall deposit with the Paying Agent sufficient funds to pay principal
and interest then so becoming due and payable in cash. 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 Holders 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 promptly in writing of any default by
the Company in making any such payment. While any such default continues, the
Trustee shall require a Paying Agent (if other than the Company) 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) shall have no further
liability for the money delivered to the Trustee. If the Company acts as Paying
Agent, then the Company shall segregate and hold in a separate trust fund for
the benefit of the Holders all money held by it as Paying Agent. The Company
shall notify the Trustee in writing at least five (5) days before the Payment
Date of the name and address of the Paying Agent if a person other than the
Trustee is named Paying Agent at any time or from time to time.

      Section 2.5 List of Holders.

      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
Holders and shall otherwise comply with TIA ss.312(a). If the Trustee is not the
Registrar, the Registrar shall furnish to the Trustee each quarter during the
term of this Indenture and at such other times as the Trustee may request in
writing, a copy of the current Securities Register as of such date as the
Trustee may reasonably require and the Company shall otherwise comply with TIA
ss.312(a).

INDENTURE - Page 11
<PAGE>
      Section 2.6 Transfer and Exchange.

            (a) The Securities are not negotiable instruments and cannot be
      transferred without the prior written consent of the Company (which
      consent shall not be unreasonably withheld). Requests to the Registrar for
      the transfer of any Account maintained for the benefit of a Holder shall
      be:

                  (i) made to the Registrar in writing on a form supplied by the
            Registrar;

                  (ii) duly executed by the Holder of the related Account, as
            reflected on the Registrar's records as of the date of receipt of
            such transfer request, or such Holder's attorney duly authorized in
            writing;

                  (iii) accompanied by the written consent of the Company to the
            transfer (which consent may not be unreasonably withheld); and

                  (iv) if requested by the Registrar, an opinion of Holder's
            counsel (which counsel shall be reasonably acceptable to the
            Registrar) that the transfer does not violate any applicable
            securities laws and/or a signature guarantee.

            (b) Upon transfer of a Security, the Company, or the Registrar on
      behalf of the Company, will provide the new registered owner of the
      Security with a Written Confirmation which will evidence the transfer of
      the Account in the Securities Register.

            (c) The Company or the Registrar may assess reasonable service
      charges to a Holder for any registration or transfer or exchange, and 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
      exchange pursuant to Section 9.5 hereof).

            (d) With respect to the relevant Regular Record Date, the Company
      shall treat the individual or entity listed on each Account maintained by
      the Registrar as the absolute owner of the Security represented thereby
      for purposes of receiving payments thereon and for all other purposes
      whatsoever.

      Section 2.7 Payment of Principal and Interest; Principal and Interest
Rights Preserved.

            (a) Each Security shall accrue interest at the rate specified for
      such Security in the Securities Register and such interest shall be
      payable on each Payment Date following the Issue Date for such Security,
      until the principal thereof becomes due and payable. Any installment of
      interest payable on a Security that is caused to be punctually paid or
      duly provided for by the Company on the applicable Payment Date shall be
      paid to the Holder in whose name such Security is registered in the
      Securities Register on the applicable Regular Record Date with respect to
      the Securities outstanding, by electronic deposit to such Holder's Payment
      Account as it appears in the Securities Register on such Regular Record
      Date. The payment of any interest payable in connection with the payment
      of any principal payable with respect to such Security on a Maturity Date
      shall

INDENTURE - Page 12
<PAGE>
      be payable as provided below. In the event any payments made by electronic
      deposit are not accepted into the Holder's Payment Account for any reason,
      such funds shall be held in accordance with Sections 2.4 and 8.3 hereof.
      Any installment of interest not punctually paid or duly provided for shall
      be payable in the manner and to the Holders as specified in Section 2.11
      hereof.

            (b) Each of the Securities shall have stated maturities of principal
      as shall be indicated on such Securities or in the Written Confirmation
      and as set forth in the Securities Register. The principal of each
      Security shall be paid in full as of the Maturity Date thereof pursuant to
      Section 2.1(d), unless the term of such Security is renewed pursuant to
      Section 2.1(e) hereof or such Security becomes due and payable at an
      earlier date by acceleration, redemption, repurchase or otherwise.
      Interest on each Security shall be due and payable on each Payment Date at
      the interest rate applicable to such Security for the Interest Accrual
      Period related to such Security and such Payment Date. Notwithstanding any
      of the foregoing provisions with respect to payments of principal of and
      interest on the Securities, if the Securities have become or been declared
      due and payable following an Event of Default, then payments of principal
      of and interest on the Securities shall be made in accordance with Article
      VI hereof. If definitive, certificated securities are issued, then the
      principal payment made on any Security on any Maturity Date (or the
      Redemption Price or the Repurchase Price of any Security required to be
      redeemed or repurchased, respectively), and any accrued interest thereon,
      shall be payable on or after the Maturity Date, Redemption Date or the
      Repurchase Date therefore at the office or agency of the Company
      maintained by it for such purpose pursuant to Section 2.3 hereof or at the
      office of any Paying Agent for such Security.

            (c) All computations of interest due with respect to any Security
      shall be made, unless otherwise specified in the Security, based upon the
      actual number of days (e.g., 365 or 366) in the applicable year.

      Section 2.8 Reserved.

      Section 2.9 Outstanding Securities.

            (a) The Securities outstanding at any time are the outstanding
      principal balances of all Accounts representing the Securities maintained
      by the Company or such other entity as the Company designated as
      Registrar.

            (b) If the principal amount of any Security is considered paid under
      Section 4.1 hereof, it ceases to be outstanding and interest on it ceases
      to accrue.

            (c) Subject to Section 2.10 hereof, a Security does not cease to be
      outstanding because the Company or an Affiliate of the Company holds the
      Security.

      Section 2.10 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 any Affiliate of the Company shall be considered as though not
outstanding, except that for purposes of

INDENTURE - Page 13
<PAGE>
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities that a Responsible Officer of the
Trustee actually knows to be so owned shall be so disregarded.

      Section 2.11 Defaulted Interest.

      If the Company defaults in a payment of interest on any Security, it shall
pay the defaulted interest plus, to the extent lawful, any interest payable on
the defaulted interest, to the Holder of such Security on a subsequent special
Payment Date, which date shall be at the earliest practicable date, but in all
events within fifteen (15) days following the scheduled Payment Date of the
defaulted interest, in each case at the rate provided in the Security. The
Company shall, with written notification to the Trustee, fix or cause to be
fixed each such special record date and payment date. Prior to any such special
Payment Date, the Company (or the Trustee, in the name of and at the expense of
the Company) shall mail to Holder(s) a notice that states the special Payment
Date and the amount of such interest to be paid.

      Section 2.12 Temporary Notes.

      If Securities are issued in certificated form in the limited circumstances
contemplated under Section 2.14(b), pending the preparation of definitive
Securities, the Company may execute, and direct that the Trustee authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities, in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

      If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Registrar designated pursuant to Section 2.3, without charge to
the Holder.

      Upon surrender for cancellation of any one or more temporary Securities,
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of authorized
denominations. Until so exchanged the temporary Securities shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities.

      Section 2.13 Execution, Authentication And Delivery.

            (a) Subject to subsection (b) below, the Securities shall be
      executed on behalf of the Company by its President or any Executive or
      Senior Vice President and attested by its Secretary or Assistant
      Secretary. The signature of any of these officers on the Securities may be
      manual or facsimile. Securities bearing the manual or facsimile signatures
      of individuals who were at any time the proper officers of the Company
      shall bind the Company, notwithstanding that such individuals or any of
      them have ceased to

INDENTURE - Page 14
<PAGE>
      hold such offices prior to the authentication and delivery of such
      Securities or did not hold such offices at the date of such Securities.

            At the time of and from time to time after the execution and
      delivery of this Indenture, the Company will deliver definitive or
      certificated forms of Securities, if any, executed by the Company to the
      Trustee for authentication, together with a direction from the Company for
      the authentication and delivery of such Securities. The Trustee in
      accordance with such direction from the Company shall authenticate and
      deliver such Securities as in this Indenture provided and not otherwise.
      Securities issued hereunder shall be dated as of their Issue Date.

            No Security shall be entitled to any benefit under this Indenture or
      be valid or obligatory for any purpose unless there appears on such
      Security an authentication executed by or on behalf of the Trustee by
      manual or facsimile signature, and such authentication upon any Security
      shall be conclusive evidence, and the only evidence, that such Security
      has been duly authenticated and delivered hereunder and is entitled to the
      benefits of the Indenture.

            (b) Notwithstanding the preceding subsection (a) of this Section, in
      connection with the issuance of each Security in book-entry form pursuant
      to Section 2.14, each Security shall be deemed to be executed and attested
      to by the Company and authenticated and delivered by the Trustee, in the
      same manner as provided in the preceding subsection (a), upon the delivery
      by the Company (or the Company's duly authorized Agent) to the Holder of
      such Security of a Written Confirmation, with a copy of such Written
      Confirmation delivered to the Trustee, and the establishment by the
      Registrar of an Account for such Security in the name of the Holder
      pursuant to Section 2.14 hereof.

      Section 2.14 Book-Entry Registration.

            (a) The Registrar shall maintain a book-entry registration and
      transfer system through the establishment and maintenance of Accounts for
      the benefit of Holders of Securities as the sole method of recording the
      ownership and transfer of ownership interests in such Securities. The
      registered owners of the Accounts established by the Registrar in
      connection with the purchase or transfer of the Securities shall be deemed
      to be the Holders of the Securities outstanding for all purposes under
      this Indenture. The Company (or its duly authorized Agent) shall promptly
      notify the Registrar of the acceptance of a subscriber's order to purchase
      a Security by providing a copy of the accepted Subscription Agreement and
      the related Written Confirmation, and upon receipt of such notices, the
      Registrar shall establish an Account for such Security by recording a
      credit to its book-entry registration and transfer system to the Account
      of the related Holder of such Security for the principal amount of such
      Security owned by such Holder and issue a Written Confirmation to the
      Holder, with a copy being delivered to the Trustee, on behalf of the
      Company. The Registrar shall make appropriate credit and debit entries
      within each Account to record all of the applicable actions under this
      Indenture that relate to the ownership of the related Security and issue
      Written Confirmations to the related Holders as set forth herein, with
      copies being delivered to the Trustee, on behalf

INDENTURE - Page 15
<PAGE>
      of the Company. For example, the total amount of any principal and/or
      interest due and payable to the Holders of the Accounts maintained by the
      Registrar as provided in this Indenture shall be credited to such Accounts
      by the Registrar within the time frames provided in this Indenture, and
      the amount of any payments of principal and/or interest distributed to the
      Holders of the Accounts as provided in this Indenture shall be debited to
      such Accounts by the Registrar. The Trustee shall review the book-entry
      registration and transfer system as it deems necessary to ensure the
      Registrar's compliance with the terms of the Indenture.

            (b) Book-entry Accounts evidencing ownership of the Securities shall
      be exchangeable for definitive or certificated forms of Securities in
      denominations of $1,000 and any amount in excess thereof and fully
      registered in the names as each Holder directs only if (i) the Company at
      its option advises the Trustee and the Registrar in writing of its
      election to terminate the book-entry system, or (ii) after the occurrence
      of any Event of Default, Holders of a majority of the aggregate
      outstanding principal amount of the Securities (as determined based upon
      the latest quarterly statement provided to the Trustee pursuant to Section
      2.5 hereof) advise the Trustee in writing that the continuation of the
      book-entry system is no longer in the best interests of such Holders and
      the Trustee notifies all Holders of the Securities, as the case may be, of
      such event and the availability of certificated forms of securities to the
      Holders of Securities, as the case may be, requesting such Securities in
      certificated form.

      Section 2.15 Initial and Periodic Statements.

            (a) Subject to the rejection of a Subscription Agreement pursuant to
      Section 2.2(a), the Registrar shall send Written Confirmations to initial
      purchasers, registered owners, registered pledgees, former registered
      owners and former pledgees, within two (2) Business Days of its receipt of
      proper notice regarding the purchase, transfer or pledge of a Security,
      with copies of such Written Confirmations being delivered to the Trustee,
      on behalf of the Company.

            (b) The Registrar shall send each Holder of a Security (and each
      registered pledgee) via U.S. mail not later than ten (10) Business Days
      after each quarter end in which such Holder had an outstanding balance in
      such Holder's Account, a statement which indicates as of the quarter end
      preceding the mailing: (i) the balance of such Account; (ii) interest
      credited for the period; (iii) repayments, redemptions or repurchases, if
      any, during the period; and (iv) the interest rates paid on the Securities
      in such Account during the period. The Company shall provide additional
      statements as the Holders or registered pledgees of the Securities may
      reasonably request from time to time. The Registrar may charge such
      Holders or pledgees requesting such statements a fee to cover the charges
      incurred by the Registrar in providing such additional statements.

      Section 2.16 Appointment of Agents.

      The Company may from time to time engage Agents to perform its obligations
and exercise its rights and discretion under the terms of this Indenture. In
each such case, the Company will provide the Trustee with a copy of each
agreement under which any such Agent is

INDENTURE - Page 16
<PAGE>
engaged and the name, address, telephone number and capacity of the Agent
appointed. If any such Agent shall resign, or such Agent's engagement is
terminated by the Company, subsequent to the Agent's appointment by the Company
under this Section 2.16, the Company shall promptly notify the Trustee of such
resignation or termination, along with the name, address, telephone number and
capacity of any successor Agent. Notwithstanding any engagement of an Agent
hereunder, the Company shall remain obligated to fulfill each of its obligations
under this Indenture.

                                  ARTICLE III
                            REDEMPTION AND REPURCHASE

      Section 3.1 Redemption of Securities at the Company's Election.

            (a) The Company may redeem, in whole or in part, any Security prior
      to the scheduled Maturity Date of the Security by providing pursuant to
      Section 2.1(f) a Redemption Notice to the Holder thereof listed on the
      records maintained by the Registrar, which notice shall include the
      Redemption Date and the Redemption Price to be paid to the Holder on the
      Redemption Date. No interest shall accrue on a Security to be redeemed
      under this Section 3.1 for any period of time after the Redemption Date
      for such Security, provided that the Company or the Paying Agent has
      timely tendered the Redemption Price to the Holder.

            (b) The Company shall have no mandatory redemption or sinking fund
      obligations with respect to any of the Securities.

            (c) In its sole discretion, the Company may offer certain Holders
      the ability to extend the maturity of an existing Security through the
      redemption of such Security and the issuance of a new Security. This
      redemption option shall not be subject to the 30 day notice of redemption
      described in Section 2.1(f).

      Section 3.2 Repurchase of Securities at the Holder's Request.

            (a) Repurchase Upon Death or Disability. Subject to subsection (c)
      below, within forty-five (45) days of the death or Total Permanent
      Disability of a Holder who is a natural person (including Securities held
      in an individual retirement account), the estate of such Holder (in the
      event of death) or such Holder (in the event of Total Permanent
      Disability) may request that the Company repurchase, in whole and not in
      part, without penalty, the Security held by such Holder, by delivering to
      the Company a Repurchase Request. If a Security is held jointly by natural
      persons who are legally married, then a Repurchase Request may be made
      when either registered Holder of such Security dies or becomes subject to
      a Total Permanent Disability, the surviving Holder or the disabled Holder
      may request that the Company repurchase in whole and not in part, without
      penalty, such Security as jointly held by the Holders by delivering to the
      Company a Repurchase Request. In the event a Security is held jointly by
      two or more natural persons that are not legally married, neither of these
      persons shall have the right to request that the Company repurchase such
      Security unless all joint holders of such Security have either died or
      suffered a Total Permanent Disability. If the Security is held

INDENTURE - Page 17
<PAGE>
      by a Holder who is not a natural person, such as a trust, partnership,
      corporation or other similar entity, the right to request repurchase upon
      death or disability does not apply.

            (b) Repurchase Upon Holder's Election. Subject to subsection (c)
      below, a Holder may request the Company to repurchase, in whole and not in
      part, the Security held by such Holder by delivering a Repurchase Request
      to the Company; provided that an early Repurchase Penalty will be deducted
      from the payment of such Holder's Repurchase Price on the Repurchase Date,
      unless the Repurchase Request is given pursuant to paragraph (a) above. If
      a repurchase is requested pursuant to this subsection (b), then the early
      repurchase penalty (the "Repurchase Penalty") shall equal the following:
      (i) with respect to a Security with a three (3) month maturity, the
      interest accrued on a simple interest basis on such Security from the
      Issue Date to the Repurchase Date at the existing interest rate thereof,
      but not to exceed three (3) months of simple interest on such Security, or
      (ii) with respect to a Security with a maturity of six (6) months or
      longer, the interest accrued on a simple interest basis on such Security
      from the Issue Date to the Repurchase Date at the existing interest rate
      thereof, but not to exceed six (6) months of simple interest on such
      Security.

            (c) Limitation on Repurchases. The Company will be required to
      repurchase Securities for which Repurchase Requests have been received
      pursuant to paragraphs (a) and (b) above, except to the extent that the
      aggregate Repurchase Price for all Securities for which Repurchase
      Requests are then outstanding would exceed $1 million in any calendar
      quarter. For the purposes of applying such $1 million limit on the
      aggregate Repurchase Price for outstanding Repurchase Requests, such
      outstanding Repurchase Requests will be honored in the order received, and
      any Repurchase Request not paid in the quarter received due to this
      limitation will be honored in the subsequent quarter, to the extent
      possible, subject to the applicability of such $1 million limit on
      aggregate Repurchase Request in each subsequent quarter.

            (d) Repurchase Date. If a Security for which a Repurchase Request
      has been received during the then current calendar quarter is determined
      not to be subject to the limitation in subsection (c) above and thus, will
      be repurchased during the current quarter, then the Company shall
      designate a date for the repurchase of such Security (the "Repurchase
      Date"), which date shall not be more than ten (10) days after the
      Company's receipt of the Repurchase Request or, in the case of a
      Repurchase Request following the death or Total Permanent Disability of
      the Holder, ten (10) days after the Company's receipt of satisfactory
      establishment of such Holder's death or Total Permanent Disability. On the
      Repurchase Date, the Company shall pay the Repurchase Price to the Holder
      (or the estate of the Holder, in the case of a request following death) in
      accordance with Section 2.7. With respect to a Security for which a
      Repurchase Request has been received during a prior calendar quarter and
      for which the Repurchase Price was not paid during such prior calendar
      quarter, but rather the Repurchase Request has been carried over to and is
      still outstanding in the current calendar quarter (because of the
      limitation in subsection (c) above), the Company shall designate a
      Repurchase Date not later than the tenth (10th) day after the start of
      such calendar quarter, unless subsection (c) is again applicable, in which
      case such obligation shall be met not later than the tenth (10th) day
      after the start of the next calendar quarter during which such limitation
      is no

INDENTURE - Page 18
<PAGE>
      longer applicable. No interest shall accrue on a Security to be
      repurchased under this Section 3.2 for any period of time on or after the
      Repurchase Date for such Security, provided that the Company or the Paying
      Agent has timely tendered the Repurchase Price to the Holder or the estate
      of the Holder, as the case may be.

            (e) Waiver and Modification of Repurchase Policies. The Company may
      waive or reduce any early Repurchase Penalty in its sole discretion and
      may modify at any time its policy on the repurchase of Securities at the
      request of Holders; provided that no such modification shall adversely
      affect the rights of Holders to the repurchase of Securities for which
      Repurchase Requests are then outstanding.

                                   ARTICLE IV
                                    COVENANTS

      Section 4.1 Payment of Securities.

            (a) The Company shall duly pay the principal of and interest on each
      Security on the dates and in the manner provided under this Indenture.
      Principal and interest (to the extent such interest is paid in cash) shall
      be considered paid on the date due if the Paying Agent, if other than the
      Company, holds at least one Business Day before that date money deposited
      by the Company in immediately available funds and designated for and
      sufficient to pay all principal and interest then due; provided, however,
      that principal and interest shall not be considered paid within the
      meaning of this Section 4.1 if money is held by the Paying Agent for the
      benefit of holders of Senior Debt pursuant to the provisions of Article X
      hereof. Such Paying Agent shall return to the Company, no later than five
      (5) days following the date of payment, any money (including accrued
      interest) that exceeds such amount of principal and interest paid on the
      Securities in accordance with this Section 4.1.

      To the extent lawful, the Company shall pay interest (including
      Post-Petition Interest in any proceeding under any Bankruptcy Law) on
      overdue principal at the rate borne by the Securities, compounded
      semi-annually; it shall pay interest (including Post-Petition Interest in
      any proceeding under any Bankruptcy Law) on overdue installments of
      interest (without regard to any applicable grace period) at the same rate,
      compounded semi-annually.

      Section 4.2 Maintenance of Office or Agency.

            (a) The Company will maintain an office or agency (which may be an
      office of the Trustee, Registrar or co-registrar) where Securities may be
      surrendered for registration of transfer or exchange and where notices and
      demands to or upon the Company in respect of the Securities and this
      Indenture may be served. The Company will give prompt written notice to
      the Trustee of the location, and any change in the location, of such
      office or agency. If at any time the Company shall fail to maintain any
      such required office or agency or shall fail to furnish the Trustee with
      the address thereof, such presentations, surrenders, notices and demands
      may be made or served at the Corporate Trust Office of the Trustee.

INDENTURE - Page 19
<PAGE>
            (b) The Company may also from time to time designate one or more
      other offices or agencies where the Securities may be presented or
      surrendered for any or all such purposes and may from time to time rescind
      such designations. The Company will give prompt written notice to the
      Trustee of any such designation or rescission and of any change in the
      location of any such other office or agency.

            (c) The Company hereby designates its office at 27051 Towne Centre
      Drive, Suite 100, Foothill Ranch, California 92610, as one such office or
      agency of the Company in accordance with Section 2.3.

      Section 4.3 SEC Reports and Other Reports.

            (a) The Company shall file with the Trustee, within 45 days after
      filing with the SEC, copies of the annual reports and of the information,
      documents, and other reports (or copies of such portions of any of the
      foregoing as the SEC may by rules and regulations prescribe) that the
      Company is required to file with the SEC pursuant to Section 13 or 15(d)
      of the Exchange Act. If the Company is not subject to the requirements of
      such Section 13 or 15(d) of the Exchange Act, the Company shall continue
      to file with the SEC and the Trustee on the same timely basis such
      reports, information and other documents as it would file if it were
      subject to the requirements of Section 13 or 15(d) of the Exchange Act.
      The Company shall file with the Trustee and the SEC, in accordance with
      the rules and regulations prescribed by the SEC, such additional
      information, documents and reports with respect to compliance by the
      Company with the conditions and covenants of this Indenture as may be
      required from time to time by such rules and regulations, and the Company
      shall otherwise comply with the provisions of TIA ss.314(a).
      Notwithstanding anything to the contrary herein, the Trustee shall have no
      duty to review such documents for purposes of determining compliance with
      any provisions of the Indenture.

            (b) So long as any of the Securities remain outstanding, the Company
      shall cause an annual report to stockholders and each quarterly or other
      financial report furnished by it generally to stockholders to be filed
      with the Trustee at the time of such mailing or furnishing to
      stockholders. If the Company is not required to furnish annual or
      quarterly reports to its stockholders pursuant to the Exchange Act, the
      Company shall cause its financial statements, including any notes thereto
      (and, with respect to annual reports, an auditors' report by the Company's
      certified independent accountants) and a "Management's Discussion and
      Analysis of Financial Condition or Plan of Operations," comparable to that
      which would have been required to appear in annual or quarterly reports
      filed under Section 13 or 15(d) of the Exchange Act to be so filed with
      the Trustee within 120 days after the end of each of the Company's fiscal
      years and within 60 days after the end of each of the first three quarters
      of each such fiscal year.

            (c) The Company, or such other entity as the Company shall designate
      as Registrar, shall provide the Trustee with quarterly management reports
      which provide the Trustee with such information regarding the Accounts
      maintained by the Company for the benefit of the Holders of the Securities
      as the Trustee may reasonably request which information shall include at
      least the following for the preceding quarterly period: (i) the

INDENTURE - Page 20
<PAGE>
      outstanding balance of each Account at the end of the period; (ii)
      interest credited for the period; (iii) repayments, repurchases and
      redemptions, if any, made during the period; and (iv) the interest rate
      paid on each Security in such Account maintained by the Registrar during
      the period.

      Section 4.4 Compliance Certificate.

            (a) The Company shall deliver to the Trustee, within 120 days after
      the end of each Fiscal Year, beginning in 2003, an Officers' Certificate
      stating that a review of the activities of the Company 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, provisions and conditions hereof (or, if a Default or Event of
      Default shall have occurred, describing all such Defaults or Events of
      Default of which he or she may have knowledge and what action the Company
      is taking or proposes to take with respect thereto) and that to the best
      of his/her knowledge no event has occurred and remains in existence by
      reason of which payments on account of the principal of or interest, if
      any, on the Securities are prohibited or if such event has occurred, a
      description of the event and what action the Company is taking or proposes
      to take with respect thereto.

            (b) So long as not contrary to the then current recommendations of
      the American Institute of Certified Public Accountants, the annual
      financial statements delivered pursuant to Section 4.3 above shall be
      accompanied by a written statement of the Company's independent public
      accountants that in making the examination necessary for certification of
      such financial statements nothing has come to their attention which would
      lead them to believe that the Company has violated the provisions of
      Section 4.1 of this Indenture or, if any such violation has occurred,
      specifying the nature and period of existence thereof, it being understood
      that such accountants shall not be liable directly or indirectly to any
      Person for any failure to obtain knowledge of any such violation.

            (c) The Company will, so long as any of the Securities are
      outstanding, deliver to the Trustee, forthwith upon any Officer becoming
      aware of any Default or Event of Default, an Officers' Certificate
      specifying such Default or Event of Default and what action the Company is
      taking or proposes to take with respect thereto.

      Section 4.5 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 covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all beneficial 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

INDENTURE - Page 21
<PAGE>
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 4.6 Liquidation.

      The Board of Directors or the stockholders of the Company shall not adopt
a plan of liquidation that provides for, contemplates or the effectuation of
which is preceded by (a) the sale, lease, conveyance or other disposition of all
or substantially all of the assets of the Company, otherwise than substantially
as an entirety (Section 5.1 of this Indenture being the Section hereof which
governs any such sale, lease, conveyance or other disposition substantially as
an entirety), and except for any securitization transaction by the Company, and
(b) the distribution of all or substantially all of the proceeds of such sale,
lease, conveyance or other disposition and of the remaining assets of the
Company to the holders of capital stock of the Company, unless the Company,
prior to making any liquidating distribution pursuant to such plan, makes
provision for the satisfaction of the Company's Obligations hereunder and under
the Securities as to the payment of principal and interest.

      Section 4.7 Financial Covenants

                                   ARTICLE VI
                              DEFAULTS AND REMEDIES

      Section 6.1 Events of Default.

      An "Event of Default" occurs if:

            (a) the Company fails to pay interest on a Security when the same
      becomes due and payable and such failure continues for a period of fifteen
      (15) days, whether or not such payment is prohibited by the provisions of
      Article X hereof;

            (b) the Company fails to pay the principal of any Security when the
      same becomes due and payable at maturity, on a Repurchase Date, Redemption
      Date or Payment Date or otherwise, and such failure continues for a period
      of ten (10) days, whether or not prohibited by the provisions of Article X
      hereof;

            (c) the Company fails to observe or perform any material covenant,
      condition or agreement on the part of the Company under this Indenture or
      the breach by the

INDENTURE - Page 23
<PAGE>
      Company of any material representation or warranty of the Company under
      this Indenture;

            (d) the Company defaults in any other material financial obligation
      of the Company;

            (e) the Company pursuant to or within the meaning of any Bankruptcy
      Law (i) commences a voluntary case; (ii) consents to the entry of an order
      for relief against it in an involuntary case; (iii) consents to the
      appointment of a custodian of it or for all or substantially all of its
      property; (iv) makes a general assignment for the benefit of its
      creditors; or (v) admits in writing its inability to pay debts as the same
      become due; or

            (f) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that (i) is for relief against the Company in an
      involuntary case; (ii) appoints a custodian of the Company or for all or
      substantially all of its property; (iii) orders the liquidation of the
      Company, and in each case the order or decree remains unstayed and in
      effect for 120 consecutive days.

      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 clauses (c) or (d) of this Section 6.1 (except for a
Default with respect to Section 4.6 or 5.1) is not an Event of Default until the
Trustee or the Holders of at least a majority in principal amount of the then
outstanding Securities notify the Company of the Default and the Company does
not cure the Default or such Default is not waived within thirty (30) days after
receipt of the notice pursuant to Section 6.4. The notice must specify the
Default, demand that it be remedied and state that the notice is a "Notice of
Default."

      Section 6.2 Acceleration.

      If an Event of Default (other than an Event of Default specified in
clauses (e) or (f) of Section 6.1) occurs and is continuing, the Trustee by
notice to the Company or the Holders of at least a majority in principal amount
of the then outstanding Securities by written notice to the Company and the
Trustee may declare the unpaid principal of and any accrued interest on all the
Securities to be due and payable. Upon such declaration, all unpaid principal of
and accrued interest on all Securities shall be due and payable immediately;
provided, however, that if any Indebtedness or Obligation is outstanding
pursuant to the Senior Debt, such a declaration of acceleration by the Holders
shall not become effective until the earlier of (i) the day which is five (5)
Business Days after the receipt by each of the Company and the holders of Senior
Debt of such written notice of acceleration or (ii) the date of acceleration of
any Indebtedness under any Senior Debt. If an Event of Default specified in
clause (e) or (f) of Section 6.1 occurs, all unpaid principal of and accrued
interest on all Securities 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.

INDENTURE - Page 24
<PAGE>
      Section 6.3 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 Holder 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 6.4 Waiver of Past Defaults.

      Holders of a majority in principal amount of the then outstanding
Securities by notice to the Trustee may, on behalf of the Holders of all
Securities, waive any existing Default or Event of Default and its consequences
under this Indenture, including without limitation a rescission of an
acceleration pursuant to Section 6.2, except for a continuing Default or Event
of Default in the payment of interest on or the principal of any Security held
by a non-consenting Holder, or except for a waiver that would conflict with any
judgment or decree. Upon actual receipt of any such notice of waiver by a
Responsible Officer of the Trustee, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

      Section 6.5 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, provided, that indemnification for the Trustee's fees and
expenses, in a form reasonably satisfactory to the Trustee, shall have been
provided. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture, that the Trustee determines may be unduly
prejudicial to the rights of other Holders, or that may involve the Trustee in
personal liability.

      Section 6.6 Limitation on Suits.

      A Holder may pursue a remedy with respect to this Indenture or the
Securities only if:

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

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

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

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

INDENTURE - Page 25
<PAGE>
            (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 Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over another Holder.

      Section 6.7 Rights of Holders to Receive Payment.

      Notwithstanding any other provision of this Indenture, but subject to
Article X hereof, 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.

      Section 6.8 Collection Suit by Trustee.

      If an Event of Default specified in Section 6.1 (a) or (b) occurs and is
continuing, the Trustee is authorized to 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, to the extent lawful, interest and such further amount as
shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

      Section 6.9 Trustee May File Proofs of Claim.

            (a) The Trustee is authorized to 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 (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel) and the Holders allowed in any judicial proceedings
      relative to the Company (or any other obligor upon the Securities), its
      creditors or its property and shall be entitled and empowered to collect,
      receive and distribute any money or other property payable or deliverable
      on any such claims and any custodian in any such judicial proceeding is
      hereby authorized by each Holder to make such payments to the Trustee, and
      in the event that the Trustee shall consent to the making of such payments
      directly to the Holders, to pay to the Trustee any amount due to it for
      the reasonable compensation, expenses, disbursements and advances of the
      Trustee, its agents and counsel, and any other amounts due the Trustee
      under Section 7.7 hereof. To the extent that the payment of any such
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel, and any other amounts due the Trustee under Section
      7.7 hereof out of the estate in any such proceeding, shall be denied for
      any reason, payment of the same shall be secured by a lien on, and shall
      be paid out of, any and all distributions, dividends, money, securities
      and other properties which the Holders of the Securities may be entitled
      to receive in such proceeding whether in liquidation or under any plan of
      reorganization or arrangement or otherwise. Nothing herein contained shall
      be deemed to authorize the Trustee to authorize or consent to or accept or
      adopt on

INDENTURE - Page 26
<PAGE>
      behalf of any Holder 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 Holder in any such proceeding.

            (b) If the Trustee does not file a proper claim or proof of debt in
      the form required in any such proceeding prior to 30 days before the
      expiration of the time to file such claims or proofs, then any holder of
      Senior Debt shall have the right to demand, sue for, collect and receive
      the payments and distributions in respect of the Securities which are
      required to be paid or delivered to the holders of Senior Debt as provided
      in Article X hereof and to file and prove all claims therefor and to take
      all such other action in the name of the Holders or otherwise, as such
      holder of Senior Debt may determine to be necessary or appropriate for the
      enforcement of the provisions of Article X hereof.

      Section 6.10 Priorities.

      If the Trustee collects any money pursuant to this Article, it shall,
subject to the provisions of Article X hereof, pay out the money in the
following order:

            (a) First: to the Trustee, its agents and attorneys for amounts due
      under Section 7.7, including payment of all compensation, expenses and
      liabilities incurred, and all advances made, if any, by the Trustee and
      the costs and expenses of collection;

            (b) Second: to holders of Senior Debt to the extent required by
      Article X hereof;

            (c) Third: to Holders 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

            (d) Fourth: to the Company or to such party as a court of competent
      jurisdiction shall direct.

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

      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 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 6.7, or a suit by Holders of more than fifty percent (50%)
in principal amount of the then outstanding Securities.

                                    TRUSTEE

      Section 7.1 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:

                  (1) The duties of the Trustee shall be determined solely by
            the express provisions of this Indenture and the Trustee need
            perform only those duties that are specifically set forth in this
            Indenture and no others, and no implied covenants or obligations
            shall be read into this Indenture against the Trustee.

                  (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 resolutions,
            statements, reports, documents, orders, certificates, opinions or
            other instruments furnished to the Trustee and conforming to the
            requirements of this Indenture. However, in the case of any of the
            above that are specifically required to be furnished to the Trustee
            pursuant to this Indenture, the Trustee shall examine them to
            determine whether they substantially conform to the requirements of
            this Indenture.

            (c) The Trustee may not be relieved from liabilities 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)
            (2) of this Section.

                  (2) The Trustee shall not be liable for any error of judgment
            made in good faith by a Responsible Officer, unless it is proved
            that the Trustee was negligent or willful in ascertaining the
            pertinent facts.

                  (3) The Trustee shall not be liable to the Holders 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 6.5.

            (d) Whether or not therein expressly so provided, 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) No provision of this Indenture shall require the Trustee to
      expend or risk its own funds or incur any liability. 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.

INDENTURE - Page 28
<PAGE>
            (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 7.2 Rights of Trustee.

            (a) The Trustee may conclusively rely upon any document believed by
      it to be genuine and to have been signed or presented to it by the proper
      Person. The Trustee need not investigate any fact or matter stated in the
      document. The Trustee shall have no duty to inquire as to the performance
      of the Company's covenants in Article IV hereof. In addition, the Trustee
      shall not be deemed to have knowledge of any Default or any Event of
      Default except any Default or Event of Default of which the Trustee shall
      have received written notification or obtained actual knowledge.

            (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. The
      Trustee may consult with counsel and the written advice of such counsel or
      any Opinion of Counsel shall be full and complete authorization and
      protection from liability in respect of any action taken, suffered or
      omitted by it hereunder in good faith and in reliance thereon.

            (c) The Trustee may act through agents, attorneys, custodians or
      nominees and shall not be responsible for the misconduct or negligence or
      the supervision of any agents, attorneys, custodians or nominees appointed
      by it 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 the
      rights or powers conferred upon it by this Indenture.

            (e) Unless otherwise specifically provided in this Indenture, any
      demand, request, direction or notice from the Company shall be sufficient
      if signed by an Officer of the Company.

            (f) The Trustee shall not be deemed to have notice of an Event of
      Default for any purpose under this Indenture unless notified of such Event
      of Default by the Company, the Paying Agent (if other than the Company) or
      a Holder of the Securities.

      Section 7.3 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
of the Company 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
Sections 7.10 and 7.11.

INDENTURE - Page 29

      Section 7.4 Trustee's Disclaimer.

      The Trustee shall not be responsible for and 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 or any
money paid to the Company or upon the Company's direction under any provision
hereof, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee and it shall not be
responsible for any statement or recital herein or any statement in the
Securities or any other document in connection with the sale of the Securities
or pursuant to this Indenture other than its certificate of authentication.

      Section 7.5 Notice of Defaults.

      If a Default or Event of Default occurs and is continuing and if it is
known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders
a notice of the Default or Event of Default within ninety (90) days after it
occurs or first becomes known to the Trustee. At least five (5) Business Days
prior to the mailing of any notice to Holders under this Section 7.5, the
Trustee shall provide the Company with notice of its intent to mail such notice.
Except in the case of a Default or Event of Default in payment on any Security,
the Trustee may withhold the notice if and so long as the Responsible Officer of
the Trustee in good faith determines that withholding the notice would have no
material adverse effect on the Holders.

      Section 7.6 Reports by Trustee to Holders.

            (a) Within sixty (60) days after December 31 of each calendar year,
      commencing December 31, 2002, the Trustee shall mail to Holders (with a
      copy to the Company) a brief report dated as of such reporting date that
      complies with TIA ss. 313(a) (but if no event described in TIA ss. 313(a)
      has occurred within the 12 months preceding the reporting date, no report
      need be prepared or transmitted). The Trustee also shall comply with TIA
      ss. 313(b). The Trustee shall also transmit by mail all reports as
      required by TIA ss. 313(c).

            (b) Commencing at the time this Indenture is qualified under the
      TIA, a copy of each report mailed to Holders under this Section 7.6 (at
      the time of its mailing to Holders) shall be filed with the SEC and each
      stock exchange, if any, on which the Securities are listed. The Company
      shall promptly notify the Trustee if and when the Securities are listed on
      any stock exchange.

      Section 7.7 Compensation and Indemnity.

            (a) The Company shall pay to the Trustee from time to time
      reasonable compensation for its acceptance of this Indenture and its
      performance of the duties and services required 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 promptly upon
      request for all reasonable disbursements, advances and expenses incurred
      or made by it in addition to the compensation for its services. Such
      expenses shall include the reasonable compensation, disbursements and
      expenses of the Trustee's agents and counsel.

            (b) The Company shall indemnify the Trustee against any and all
      losses, liabilities or expenses incurred by it arising out of or in
      connection with the acceptance or administration of its duties under this
      Indenture, except as set forth in Section 7.7(d). The Trustee shall notify
      the Company promptly of any claim for which it may seek indemnity. Failure
      by the Trustee to so notify the Company shall not relieve the Company of
      its obligations hereunder, except to the extent the Company is prejudiced
      thereby. The Company shall defend the claim and the Trustee shall
      reasonably cooperate in such defense. The Trustee may have separate
      counsel and the Company shall pay the reasonable fees and expenses of such
      one counsel. The Company need not pay for any settlement made without its
      consent, which consent shall not be unreasonably withheld.

            (c) The obligations of the Company under this Section 7.7 shall
      survive the satisfaction and discharge of this Indenture.

            (d) The Company need not reimburse any expense or indemnify against
      any loss or liability incurred by the Trustee through its own negligence,
      bad faith or willful misconduct.

            (e) 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 the Securities or to pay Senior Debt. Such lien
      shall survive the satisfaction and discharge of this Indenture.

            (f) When the Trustee incurs expenses or renders services after an
      Event of Default specified in Section 6.1(e) or (f) occurs, the expenses
      and the compensation for the services are intended to constitute expenses
      of administration under any Bankruptcy Law.

      Section 7.8 Replacement of Trustee.

            (a) 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 7.8.

            (b) The Trustee may resign at any time and be discharged from the
      trust hereby created by so notifying the Company. The Holders of a
      majority of the aggregate principal amount of the outstanding Securities
      may remove the Trustee (including any successor Trustee) at any time by so
      notifying the Trustee and the Company in writing. 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 or an
            order for relief is entered with respect to the Trustee under any
            Bankruptcy Law;

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

INDENTURE - Page 31

                  (4) the Trustee becomes incapable of acting as Trustee under
            this Indenture, or

                  (5) the Company so elects, provided such replacement Trustee
            is qualified and reasonably acceptable.

            (c) 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.

            (d) If a successor Trustee does not take office within 30 days after
      notice that the Trustee has resigned or has been removed, the Company or
      the Trustee or the Holders of at least a majority in principal amount of
      the then outstanding Securities may petition any court of competent
      jurisdiction for the appointment of a successor Trustee.

            (e) If the Trustee after written request by any Holder who has been
      a Holder for at least six (6) months fails to comply with Section 7.10,
      such Holder may petition any court of competent jurisdiction for the
      removal of the Trustee and the appointment of a successor Trustee.

            (f) 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 all Holders. The retiring Trustee shall promptly
      transfer all property held by it as Trustee to the successor Trustee,
      provided all sums owing to the Trustee hereunder have been paid and
      subject to the lien provided for in Section 7.7. Notwithstanding
      replacement of the Trustee pursuant to this Section 7.8, the Company's
      obligations under Section 7.7 hereof shall continue for the benefit of the
      retiring Trustee.

      Section 7.9 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.

            (a) There shall at all times be a Trustee hereunder which shall be a
      corporation organized and doing business under the laws of the United
      States of America or of any state or territory thereof or of the District
      of Columbia authorized under such laws to exercise corporate trustee
      power, shall be subject to supervision or examination by Federal, state,
      territorial or District of Columbia authority and shall have a combined
      capital and surplus of at least $5,000,000 as set forth in its most recent
      published annual report of condition.

            (b) This Indenture shall always have a Trustee who satisfies the
      requirements of TIA ss. 310(a)(1) and (2). The Trustee is subject to TIA
      ss. 310(b).

      Section 7.11 Preferential Collection of Claims Against Company.

      The Trustee is subject to TIA ss. 311(a), excluding any creditor

                                  ARTICLE VIII
                             DISCHARGE OF INDENTURE

      Section 8.1 Termination of Company's Obligations.

            (a) This Indenture shall cease to be of further effect (except that
      the Company's obligations under Section 7.7 and 8.4, and the Company's,
      Trustee's and Paying Agent's obligations under Section 8.3 shall survive)
      when all outstanding Securities have been paid in full and the Company has
      paid all sums payable by the Company hereunder. In addition, the Company
      may terminate all of its obligations under this Indenture if:

                  (1) the Company irrevocably deposits in trust with the Trustee
            or, at the option of the Trustee, with a trustee reasonably
            satisfactory to the Trustee and the Company under the terms of an
            irrevocable trust agreement in form and substance satisfactory to
            the Trustee, money or U.S. Government Obligations sufficient (as
            certified by an independent public accountant designated by the
            Company) 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, provided that (i) the trustee of the irrevocable
            trust shall have been irrevocably instructed to pay such money or
            the proceeds of such U.S. Government Obligations to the Trustee and
            (ii) the Trustee shall have been irrevocably instructed to apply
            such money or the proceeds of such U.S. Government Obligations to
            the payment of said principal and interest with respect to the
            Securities;

                  (2) the Company delivers to the Trustee an Officers'
            Certificate stating that all conditions precedent to satisfaction
            and discharge of this Indenture have been complied with; and

                  (3) no Default or Event of Default with respect to the
            Securities shall have occurred and be continuing on the date of such
            deposit.

      Then, this Indenture shall cease to be of further effect (except as
      provided in this paragraph), and the Trustee, on demand of the Company,
      shall execute proper instruments acknowledging confirmation of and
      discharge under this Indenture. The Company may make the deposit only if
      Article X hereof does not prohibit such payment. However, the Company's
      obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.7, 4.1, 4.2, 4.3, 7.7, 7.8,
      8.3 and 8.4 and the Trustee's and Paying Agent's obligations in Section
      8.3 shall survive until the Securities are no longer outstanding.
      Thereafter, only the Company's

INDENTURE - Page 33
<PAGE>
      obligations in Section 7.7 and 8.4 and the Company's, Trustee's and Paying
      Agent's obligations in Section 8.3 shall survive.

            (b) After such irrevocable deposit made pursuant to this Section 8.1
      and satisfaction of the other conditions set forth herein, the Trustee
      upon written request shall acknowledge in writing the discharge of the
      Company's obligations under this Indenture except for those surviving
      obligations specified above.

            (c) 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 at least one Business Day
      before such payment date in such amounts as will provide the necessary
      money. U.S. Government Obligations shall not be callable at the issuer's
      option.

      Section 8.2 Application of Trust Money.

      The Trustee or a trustee satisfactory to the Trustee and the Company shall
hold in trust money or U.S. Government Obligations deposited with it pursuant to
Section 8. 1. 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.

      Section 8.3 Repayment to Company.

            (a) The Trustee and the Paying Agent shall promptly pay to the
      Company upon written request any excess money or securities held by them
      at any time.

            (b) The Trustee and the Paying Agent shall pay to the Company upon
      written request any money held by them for the payment of principal or
      interest on the Securities that remains unclaimed for two years after the
      date upon which such payment shall have become due; provided, however,
      that the Company shall have either caused notice of such payment to be
      mailed to each Holder entitled thereto no less than 30 days prior to such
      repayment or within such period shall have published such notice in a
      newspaper of widespread circulation published in the County of Orange,
      State of California. After payment to the Company, Holders entitled to the
      money must look to the Company for payment as general creditors unless an
      applicable abandoned property law designates another Person, and all
      liability of the Trustee and such Paying Agent with respect to such money
      shall cease.

Section 8.4 Reinstatement.

      If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 8.2 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture and the Securities shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.1 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 8.2; provided, however,
that if the Company

INDENTURE - Page 34
<PAGE>
has made any payment of interest on or principal of any Securities because of
the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Securities to receive such payment, as long as no
money is owed to the Trustee by the Company, from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

                                   ARTICLE IX
                                   AMENDMENTS

      Section 9.1 Without Consent of Holders.

      The Company and the Trustee may amend this Indenture or the Securities
without the consent of any Holder:

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

            (b) to comply with Section 5.1;

            (c) to provide for additional uncertificated Securities or
      certificated Securities;

            (d) to make any change that does not adversely affect the legal
      rights hereunder of any Holder, including but not limited to an increase
      in the aggregate dollar amount of Securities which may be outstanding
      under this Indenture;

            (e) make any change in Section 3.2; provided, however, that no such
      change shall adversely affect the rights of any outstanding or issued
      Security; or

            (f) to comply with any requirements of the SEC in connection with
      the qualification of this Indenture under the TIA.

      Section 9.2 With Consent of Holders.

            (a) 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. The Holders of a
      majority in principal of the then outstanding Securities may also waive on
      behalf of all Holders any existing Default or Event of Default or
      compliance with any provision of this Indenture or the Securities.
      However, without the consent of the Holder of each Security affected, an
      amendment or waiver under this Section may not (with respect to any
      Security held by a nonconsenting Holder):

                  (i) reduce the aggregate principal amount of Securities whose
            Holders must consent to an amendment, supplement or waiver;

                  (ii) reduce the rate of or change the time for payment of
            interest, including default interest, on any Security;

INDENTURE - Page 35
<PAGE>
                  (iii) reduce the principal of or change the fixed maturity of
            any Security or alter the redemption provisions or the price at
            which the Company shall offer to purchase such Security pursuant to
            Section 3.1 of Article III hereof;

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

                  (v) modify or eliminate the right of the estate of a Holder or
            a Holder to cause the Company to repurchase a Security upon the
            death or Total Permanent Disability of a Holder pursuant to Article
            III; provided, however, that the Company may not modify or eliminate
            such right, as it may be in effect on the Issue Date, of any
            Security which was issued with such right, and after an amendment
            under this subsection 9.2(a)(v) becomes effective, the Company shall
            mail to the Holders of each Security then outstanding a notice
            briefly describing the amendment;

                  (vi) make any change in Section 6.4 or 6.7 hereof or in this
            sentence of this Section 9.2;

                  (vii) make any change in Article X that materially adversely
            affects the rights of any Holders; or

                  (viii) waive a Default or Event of Default in the payment of
            principal of or interest on any Security (except a rescission of
            acceleration of the Securities by the Holders of at least a majority
            in aggregate principal amount of the Securities and a waiver of the
            payment default that resulted from such acceleration).

            (b) It shall not be necessary for the consent of the Holders under
      this Section to approve the particular form of any proposed amendment or
      waiver, but it shall be sufficient if such consent approves the substance
      thereof.

            (c) After an amendment or waiver under this Section becomes
      effective, the Company shall mail to the Holders of each Security affected
      thereby a notice briefly describing the amendment or waiver. Any failure
      of the Company to mail such notice, or any defect therein, shall not,
      however, in any way impair or affect the validity of any such supplemental
      indenture or waiver. Subject to Sections 6.4 and 6.7 hereof, the Holders
      of a majority in principal amount of the Securities then outstanding may
      waive compliance in a particular instance by the Company with any
      provision of this Indenture or the Securities.

      Section 9.3 Compliance with Trust Indenture Act.

      If at the time this Indenture shall be qualified under the TIA, 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.

INDENTURE - Page 36
<PAGE>
      Section 9.4 Revocation and Effect of Consents.

            (a) 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. An amendment or waiver becomes
      effective in accordance with its terms and thereafter binds every Holder.

            (b) The Company may fix a record date for determining which Holders
      must consent to such amendment or waivers. If the Company fixes a record
      date, the record date shall be fixed at (i) the later of 30 days prior to
      the first solicitation of such consent or the date of the most recent list
      of Holders furnished to the Trustee prior to such solicitation pursuant to
      Section 2.5, or (ii) such other date as the Company shall designate.

      Section 9.5 Notation on or Exchange of Securities.

      The Trustee may place an appropriate notation about an amendment or waiver
on any Security, if certificated, or any Account statement. Failure to make any
notation or issue a new Security shall not affect the validity and effect of
such amendment or waiver.

      Section 9.6 Trustee to Sign Amendments, etc.

      The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article IX if, in the Trustee's reasonable discretion, the
amendment does not adversely affect the rights, duties, liabilities or
immunities of the Trustee. If it does, the Trustee may, but need not, sign it.
In signing or refusing to sign such amendment or supplemental indenture, the
Trustee shall be entitled to receive, if requested, an indemnity reasonably
satisfactory to it and to receive and, subject to Section 7.1, shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
(or written advice of counsel) as conclusive evidence that such amendment or
supplemental indenture is authorized or permitted by this Indenture, that it is
not inconsistent herewith, and that it will be valid and binding upon the
Company in accordance with its terms. The Company may not sign an amendment or
supplemental indenture until its Board of Directors approves it.

                                  SUBORDINATION

      Section 10.1 Agreement to Subordinate.

            (a) The Company agrees, and each Holder by accepting a Security
      consents and agrees, that the Indebtedness evidenced by the Securities and
      the payment of the principal of and interest on the Securities is
      subordinated in right of payment, to the extent and in the manner provided
      in this Article, to the prior payment in full, in cash, cash equivalents
      or otherwise in a manner satisfactory to the holders of Senior Debt, of
      all Obligations due in respect of Senior Debt of the Company whether
      outstanding on the date hereof or hereafter incurred, and that the
      subordination is for the benefit of the holders of Senior Debt.

      account of the Securities may consist of cash, property or securities, by
      set-off or otherwise, and a payment or distribution on account of any of
      the Securities shall include, without limitation, any redemption, purchase
      or other acquisition of the Securities.

      Section 10.2 Liquidation; Dissolution; Bankruptcy.

            (a) Upon any payment or distribution of assets of the Company of any
      kind or character, whether in cash, property or securities, to creditors

      reorganization of the Company whether voluntary or involuntary and whether
      or not involving insolvency or bankruptcy or (ii) any bankruptcy or
      insolvency case or proceeding or any receivership, liquidation,
      reorganization or other similar case or proceeding in connection
      therewith, relative to the Company or to its assets, (iii) any assignment
      for the benefit of creditors or any other marshaling of assets of the
      Company, all obligations due, or to become due, in respect of Senior Debt
      (including interest after the commencement of any such proceeding at the
      rate specified in the applicable Senior Debt) shall first interfeasibly be
      paid in full, or provision shall have been made for such payment, in cash,
      cash equivalents or otherwise in a manner satisfactory to the holders of
      Senior Debt, before any payment is made on account of the principal of or
      interest on the Securities, except that Holders may receive securities
      that are subordinated to at least the same extent as the Securities are to
      (x) Senior Debt and (y) any securities issued in exchange for Senior Debt.
      Upon any such dissolution, winding-up, liquidation or reorganization, any
      payment or distribution of assets of the Company of any kind or character,
      whether in cash, property or securities, to which the Holders of the
      Securities or the Trustee under this Indenture would be entitled, except
      for the provisions hereof, shall be paid by the Company or by any
      receiver, trustee in bankruptcy, liquidating trustee, agent or other
      Person making such payment or distribution, or by the Holders of the
      Securities or by the Trustee under this Indenture if received by them,
      directly to the holders of Senior Debt (pro rata to such holders on the
      basis of the amounts of Senior Debt held by such holders) or their
      representative or representatives, or to the trustee or trustees under any
      indenture pursuant to which any of such Senior Debt may have been issued,
      as their interests may appear, for application to the payment of Senior
      Debt remaining unpaid until all such Senior Debt has been indefeasibly
      paid in full, or provisions shall have been made for such payment, in
      cash, cash equivalents or otherwise in a manner satisfactory to the
      holders of Senior Debt, after giving effect to any concurrent payment,
      distribution or provision therefor to or for the holders of Senior Debt.

            (b) For purposes of this Article X, the words "cash, property or
      securities" shall not be deemed to include securities of the Company or
      any other corporation provided for by a plan of reorganization or
      readjustment which are subordinated, to at least the same extent as the
      Securities, to the payment of all Senior Debt then outstanding or to the

      provided in Article V shall not be deemed a dissolution, winding-up,
      liquidation or reorganization for the purposes of this Section if such
      other corporation shall, as part of such consolidation, merger, conveyance
      or transfer, comply with the conditions stated in Article V.

      Section 10.3 Default of Senior Debt.

            (a) In the event and during the continuation of any default in the
      payment of principal of (or premium, if any) or interest on any Senior
      Debt, or any amount owing from time to time under or in respect of Senior
      Debt or in the event that any nonpayment event of default with respect to
      any Senior Debt shall have occurred and be continuing and shall have
      resulted in such Senior Debt becoming or being declared due and payable
      prior to the date on which it would otherwise have become due and payable,
      or (b) in the event that any other nonpayment event of default with
      respect to any Senior Debt shall have occurred and be continuing
      permitting the holders of such Senior Debt (or a trustee on behalf of the
      holders thereof) to declare such Senior Debt due and payable prior to the
      date on which it would otherwise have become due and payable, then the
      Company shall make no payment, direct or indirect (including any payment
      which may be payable by reason of the payment of any other Indebtedness of
      the Company being subordinated to the payment of the Securities) (other
      than securities that are subordinated to at least the same extent as the
      Securities are to (x) Senior Debt and (y) any securities issued in
      exchange for Senior Debt) unless and until (i) such event of default shall
      have been cured or waived or shall have ceased to exist or such
      acceleration shall have been rescinded or annulled, or (ii) in case of any
      nonpayment event of default specified in (b), during the period (a
      "Payment Blockage Period") commencing on the date the Company and the
      Trustee receive written notice (a "Payment Notice") of such event of
      default (which notice shall be binding on the Trustee and the Holders as
      to the occurrence of such an event of default) from a holder of the Senior
      Debt to which such default relates and ending on the earliest of (A) 179
      days after such date, (B) the date, if any, on which such Senior Debt to
      which such default relates is discharged or such default is waived by the
      holders of such Senior Debt or otherwise cured and (C) the date on which
      the Trustee receives written notice from the holder of such Senior Debt to
      which such default relates terminating the Payment Blockage Period. No new
      Payment Blockage Period may be commenced within 360 days after the receipt
      by the Trustee of any prior Payment Notice. For all purposes of this
      Section 10.3, no event of default which existed or was commencing with
      respect to the Senior Debt to which a Payment Blockage Period relates on
      the date such Payment Blockage Period commenced shall be or be made the
      basis for the commencement or any subsequent Payment Blockage Period
      unless such event of default is cured or waived for a period of not less
      than 180 consecutive days.

      Section 10.4 When Distribution Must Be Paid Over.

            (a) If the Trustee or any Holder receives any payment with respect
      to the Securities, whether in cash, property or securities (other than
      securities that are subordinated to at least the same extent as the
      Securities are to (x) Senior Debt and (y) any securities issued in
      exchange for Senior Debt at a time when such payment is prohibited by
      Article X hereof), such payment shall be held by the Trustee or such

INDENTURE - Page 39
<PAGE>
      Holder, in trust for the benefit of, and shall be paid forthwith over and
      delivered to, the holders of Senior Debt (pro rata to such holders on the
      basis of the amount of Senior Debt held by such holders) for application
      to the payment of all Obligations with respect to Senior Debt remaining
      unpaid to the extent necessary to pay such Obligations in full, in cash,
      cash equivalents or otherwise in a manner satisfactory to the holders of
      Senior Debt, in accordance with the terms of such Senior Debt, after
      giving effect to any concurrent payment or distribution to or for the
      holders of Senior Debt.

            (b) With respect to the holders of Senior Debt, the Trustee
      undertakes to perform only such obligations on the part of the Trustee as
      are specifically set forth in this Article X, and no implied covenants or
      obligations with respect to the holders of Senior Debt shall be read into
      this Indenture against the Trustee. The Trustee shall not be deemed to owe
      any fiduciary duty to the holders of Senior Debt, and shall not be liable
      to any such holders if the Trustee shall pay over or distribute to or on
      behalf of Holders or the Company or any other Person money or assets to
      which any holders of Senior Debt shall be entitled by virtue of this
      Article X, except if such payment is made as a result of the willful
      misconduct or negligence of the Trustee.

      Section 10.5 Notice by Company.

      The Company shall promptly notify the Trustee and the Paying Agent in
writing of any facts known to the Company that would cause a payment of any
Obligations with respect to the Company to violate this Article, but failure to
give such notice shall not affect the subordination of the Securities to the
Senior Debt provided in this Article.

      Section 10.6 Subrogation.

      After all Senior Debt is paid in full, in cash, cash equivalents or
otherwise in a manner satisfactory to the holders of such Senior Debt, and until
the Securities are paid in full, Holders shall be subrogated (equally and
ratably with all other Indebtedness pari passu with the Securities) to the
rights of holders of Senior Debt to receive distributions applicable to Senior
Debt to the extent that distributions otherwise payable to the Holders have been
applied to the payment of Senior Debt.

      Section 10.7 Relative Rights.

            (a) This Article defines the relative rights of Holders and holders
      of Senior Debt. Nothing in this Indenture shall:

                  (1) impair, as between the Company and Holders, the
            obligations of the Company, which are absolute and unconditional, to
            pay principal of and interest on the Securities in accordance with
            their terms;

                  (2) affect the relative rights of Holders and creditors of the
            Company other than their rights in relation to holders of Senior
            Debt; or

                  (3) prevent the Trustee or any Holder from exercising its
            available remedies upon a Default or Event of Default, subject to
            the rights of holders and

INDENTURE - Page 40
<PAGE>
            owners of Senior Debt to receive distributions and payments
            otherwise payable to Holders.

            (b) If the Company fails because of this Article to pay principal of
      or interest on a Security on the due date, the failure is still a Default
      or Event of Default.

      Section 10.8 Subordination May Not Be Impaired by the Company or Holders
of Senior Debt.

            (a) No right of any present or future holder of Senior Debt to
      enforce the subordination of the Indebtedness evidenced by the Securities
      and the Obligations related thereto shall be prejudiced or impaired by any
      act or failure to act by any such holder or by the Company, the Trustee or
      any Agent or by the failure of the Company to comply with this Indenture,
      regardless of any knowledge thereof which any such holder may have or
      otherwise be charged with.

            (b) Without limiting the effect of the preceding paragraph, any
      holder of Senior Debt may at any time and from time to time without the
      consent of or notice to any other holder or to the Trustee, without
      impairing or releasing any of the rights of any holder of Senior Debt
      under this Indenture, upon or without any terms or conditions and in whole
      or in part:

                  (1) change the manner, place or term of payment, or change or
            extend the time of payment of, renew or alter any Senior Debt or any
            other liability of the Company to such holder, any security
            therefor, or any liability incurred directly or indirectly in
            respect thereof, and the provisions of this Article X shall apply to
            the Senior Debt as so changed, extended, renewed or altered;

                  (2) notwithstanding the provisions of Section 5.1 hereof,
            sell, exchange, release, surrender, realize upon or otherwise deal
            with in any manner and in any order any property by whomsoever at
            any time pledged or mortgaged to secure, or howsoever securing, any
            Senior Debt or any other liability of the Company to such holder or
            any other liabilities incurred directly or indirectly in respect
            thereof or hereof or any offset thereagainst;

                  (3) exercise or refrain from exercising any rights or remedies
            against the Company or others or otherwise act or refrain from
            acting or, for any reason, fail to file, record or otherwise perfect
            any security interest in or lien on any property of the Company or
            any other Person; and

                  (4) settle or compromise any Senior Debt or any other
            liability of the Company to such holder, or any security therefor,
            or any liability incurred directly or indirectly in respect thereof.

            (c) All rights and interests under this Indenture of any holder of
      Senior Debt and all agreements and obligations of the Trustee, the
      Holders, and the Company under Article VI and under this Article X shall
      remain in full force and effect irrespective of (i) any lack of validity
      or enforceability of any agreement or instrument relating to any

INDENTURE - Page 41
<PAGE>
      Senior Debt or (ii) any other circumstance that might otherwise constitute
      a defense available to, or a discharge of, the Trustee, any Holder, or the
      Company.

            (d) Any holder of Senior Debt is hereby authorized to demand
      specific performance of the provisions of this Article X, whether or not
      the Company shall have complied with any of the provisions of this Article
      X applicable to it, at any time when the Trustee or any Holder shall have
      failed to comply with any of these provisions. The Trustee and the Holders
      irrevocably waive any defense based on the adequacy of a remedy at law
      that might be asserted as a bar to such remedy of specific performance.

      Section 10.9 Distribution or Notice to Representative.

            (a) Whenever a distribution is to be made or a notice given to
      holders of Senior Debt, the distribution may be made and the notice given
      to their representative.

            (b) Upon any payment or distribution of assets of the Company
      referred to in this Article X, the Trustee and the Holders shall be
      entitled to rely upon any order or decree made by any court of competent
      jurisdiction in which bankruptcy, dissolution, winding-up, liquidation or
      reorganization proceedings are pending or upon any certificate of any
      representative of any holder of Senior Debt or of the liquidating trustee
      or agent or other Person making any distribution, delivered to the Trustee
      or to the Holders, for the purpose of ascertaining the Persons entitled to
      participate in such 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 Article X.

      Section 10.10 Rights of Trustee and Paying Agent.

            (a) Notwithstanding the provisions of this Article X or any other
      provision of this Indenture, the Trustee shall not be charged with
      knowledge of the existence of any facts which would prohibit the making of
      any payment or distribution by the Trustee, or the taking of any action by
      the Trustee, and the Trustee or Paying Agent may continue to make payments
      on the Securities unless it shall have received at its Corporate Trust
      Office at least five (5) Business Days prior to the date of such payment
      written notice of facts that would cause the payment of any Obligations
      with respect to the Securities to violate this Article, which notice,
      unless specified by a holder of Senior Debt as such, shall not be deemed
      to be a Payment Notice. The Trustee may conclusively rely on such notice.
      Only the Company or a holder of Senior Debt may give the notice. Nothing
      in this Article X shall apply to amounts due to, or impair the claims of,
      or payments to, the Trustee under or pursuant to Section 7.7 hereof.

            (b) The Trustee in its individual or any other capacity may hold
      Senior Debt with the same rights it would have if it were not Trustee. Any
      Agent may do the same with like rights.

INDENTURE - Page 42
<PAGE>
      Section 10.11 Authorization to Effect Subordination.

      Each Holder of a Security by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate, as between the holders of Senior Debt and the Holders, the
subordination as provided in this Article X, and appoints the Trustee his
attorney-in-fact for any and all such purposes.

      Section 10.12 Article Applicable to Paying Agent.

      In case at any time any Paying Agent (other than the Trustee or the
Company) shall have been appointed by the Company and be then acting hereunder,
the term "Trustee" as used in this Article X shall in such case (unless the
context otherwise requires) 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 X in addition to or in place of the
Trustee.

      Section 10.13 Miscellaneous.

            (a) The agreements contained in this Article X shall continue to be
      effective or be reinstated, as the case may be, if at any time any payment
      of any of the Senior Debt is rescinded or must otherwise be returned by
      any holder of Senior Debt upon the insolvency, bankruptcy or
      reorganization of the Company or otherwise, all as though such payment had
      not been made.

            (b) The Trustee shall notify all holders of Senior Debt (of whose
      identity the Trustee has received reasonable advance written notice) of
      the existence of any Default or Event of Default under Section 6.1
      promptly after a Responsible Officer of the Trustee actually becomes aware
      thereof; provided, however, that at least five (5) Business Days prior to
      the notification of any holder of Senior Debt under this Section 10.13,
      the Trustee shall provide the Company with notice of its intent to provide
      such notification, provided further, however, that no defect in the form
      or delivery of the Trustee's notice to the Company shall preclude the
      timely notice by the Trustee to the holders of Senior Debt.

                                   ARTICLE XI

                              REVERSE SIDE OF NOTE

         This Note is one of a duly authorized issue of Renewable Unsecured
Subordinated Notes of the Company designated as its Renewable Unsecured
Subordinated Notes (the "Notes") in the maximum aggregate principal amount of up
to $50,000,000, issued and to be issued under an Indenture, dated as of
________________, 2002 (the "Indenture"), between the Company and U.S. Bank
National Association, as Trustee (the "Trustee," which term includes any
successor Trustee under the Indenture). Reference is hereby made to the
Indenture and all indentures supplemental thereto for a statement of the
respective rights, limitation of rights, duties and immunities thereunder of the
Company, the Trustee and the Holders, and for a statement of the terms upon
which the Notes are, and are to be, authenticated and delivered. Capitalized and
certain other terms used herein and not otherwise defined have the meanings set
forth in the Indenture.

         The Notes are general unsecured obligations of the Company. The payment
of the principal of and interest on this Note is expressly subordinated, as
provided in the Indenture, to the payment of all Senior Debt and, by the
acceptance of this Note, the Holder hereof agrees, expressly for the benefit of
the present and future holders of Senior Debt, to be bound by the provisions of
the Indenture relating to such subordination and authorizes and appoints as such
Holder's attorney-in-fact the Trustee to take such action on such Holder's
behalf as may be necessary or appropriate to effectuate such subordination.

         The Company may, at its option, at any time redeem this Note either in
whole or from time to time in part prior to the Maturity Date by providing at
least thirty (30) days written notice to the Holder.

         If this Note shall be redeemed by call for redemption and payment be
duly provided therefor as specified in the Indenture, interest shall cease to
accrue on this Note.

         This Note may be transferred and exchanged only as provided in the
Indenture. This Note may not be assigned, transferred or otherwise alienated
without the prior written consent of the Company and shall be subject to the
Company's right to demand and receive an opinion of Holder's legal counsel
(which counsel shall be reasonably acceptable to the Company) that the transfer
does not violate any applicable securities laws. The Company may also require a
signature guarantee.

         Approximately fifteen (15) but not less than ten (10) days prior to the
Maturity Date, the Company will send the Holder a Notice of Maturity to notify
the Holder of the Maturity Date. If in the Notice of Maturity the Company does
not notify the Holder of its intention to repay this Note, and unless within
fifteen (15) days after the Maturity Date, the Holder has not demanded repayment
of this Note, this Note shall be automatically renewed for an additional term
equal to the term of the maturing Note and shall be deemed to have been renewed
by the Holder and the Company as of the Maturity Date, such that a new Note
shall be deemed to have been issued as of such Maturity Date. This Note will
continue to renew as described herein absent some action permitted under the
Indenture and this Note by either the Holder or the Company. Interest on the
renewed Note shall accrue from the Issue Date thereof, which is the first day of
such renewed term. This renewed Note will be deemed to have identical terms and
provisions as the maturing

<PAGE>
Note, including provisions relating to payment, except that the interest rate
payable during the term of the renewed Note shall be the interest rate which is
being offered by the Company on other Notes with the same term as of the Issue
Date of such renewal. If other Notes with the same term are not then being
offered on the Issue Date of such renewal, the interest rate upon renewal will
be the rate specified by the Company on or before the Maturity Date, or the
Note's existing rate if no such rate is specified. If the Company gives notice
to the Holder of the Company's intention to repay the Note at maturity, the
Company shall pay the Holder the principal amount and accrued and unpaid
interest thereon on the Maturity Date, and, provided such payment is timely
made, no interest will accrue after the Maturity Date. Otherwise, if the Holder
requests repayment within fifteen (15) days after the Maturity Date, no interest
will accrue after the Maturity Date and the Holder will be sent payment upon the
later of the Maturity Date or five (5) days following the date the Company
receives such notice from Holder; provided that any interest paid to the Holder
accruing after the Maturity Date shall be deducted from such payment

         If an Event of Default shall occur and be continuing, the outstanding
principal of this Note may be declared due and payable in the manner and with
the effect provided in the Indenture. The Company shall pay all costs of
collection, whether or not judicial proceedings are instituted, in the manner
provided in the Indenture. The Indenture provides that such declaration and its
consequences may, in certain events, be waived by the Holders of a majority in
principal amount of the Notes outstanding.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Notes at the time outstanding. The Indenture
also contains provisions permitting the Holders of specified percentages of
aggregate principal amount of the Notes at the time outstanding, on behalf of
the Holders of all of the Notes, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Note shall
be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Note.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture or amendment or modification hereof or thereof shall alter or
impair the obligation of the Company to pay the principal of and interest on
this Note at the times, place and rate and in the coin or currency herein
prescribed.

         In the event of a consolidation or merger of the Company into, or of
the transfer of its assets substantially as an entirety to, a successor entity
in accordance with the Indenture, such successor entity shall assume payment of
the Notes and the performance of every covenant of the Indenture on the part of
the Company, and in the event of any such transfer, the Company (or the
successor entity in the event of a subsequent consolidation, merger or transfer)
shall be discharged from all obligations and covenants in respect of the Notes
and the Indenture and may be dissolved and liquidated, all as more fully set
forth in the Indenture.

         The Notes are originally issuable in such denominations as may be
designated from time to time by the Company, but in no event in an original
denomination less than $1,000. As provided in the Indenture and subject to
certain limitations therein set forth, the Notes are exchangeable for a like
aggregate principal amount of Notes of a different authorized denomination
(i.e., $1,000 or any amount in excess thereof). Subject to the provisions of the
Indenture (including without limitation Section 2.6 thereof), the transfer of
this Note is registerable in the Securities Register, upon surrender of this
Note for registration of transfer at the office or agency of the Registrar duly
endorsed by or accompanied by a written instrument of transfer in the form
printed on this Note or in another form satisfactory to the Company and the
Registrar duly executed by the Holder hereof or such Holder's attorney, duly
authorized in writing, and thereupon one or more new Notes, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees. The Registrar may assess service charges
for any such registration or transfer or exchange, and the Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

         Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

         This Note shall be governed by and construed in accordance with the
laws of the State of New York, without giving effect to the conflict of law
provisions thereof.
