            CHARTER OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS
                 OF FIRST COMMUNITY BANK CORPORATION OF AMERICA

Audit Committee Purpose

         The Committee is appointed by the Board of Directors of First Community
         Bank Corporation of America (the "Company") to assist the Board in

         primary duties and responsibilities are to:

                  process and systems of internal controls regarding finance,
                  account and legal compliance.

         o        Monitor the independence and performance of the Company's
                  independent auditors and internal auditing function (including
                  an outsource service provider).

         o        Provide an avenue of communication among the independent
                  auditors, management, the internal audit department (including
                  an outsource service provider) and the Board of Directors.

         o        The Company's Audit Committee will serve as the audit
                  committee for the Company and First Community Bank of America
                  (the "Bank") and may have joint meetings serving the audit
                  requirements of both the Company and the Bank.

         The Audit Committee has the authority to conduct any investigation
         appropriate to fulfilling its responsibilities, and it has direct
         access to the independent auditors as well as anyone in the Company.

such determination date multiplied by (2) the average Last Reported Sale Price
of the Common Stock for the five Trading Days ending on such determination date,
appropriately adjusted to take into account the occurrence, during the period

and may either be paid to the Person or Persons in whose name the Senior
Convertible Notes are registered at the close of business on a Special Record
Date for the payment of such defaulted interest to be fixed by the Trustee

Convertible Notes not less than ten (10) days prior to such Special Record Date,

requirements of any securities exchange, if any, on which the Senior Convertible
Notes may be listed, and upon such notice as may be required by any such
exchange, all as more fully provided in the Original Indenture.

amount of the Senior Convertible Notes for the Applicable Five Day Trading
Period with respect to such interest period equals 120% or more of such
principal amount of Senior Convertible Notes. The amount of Contingent Interest
payable per $1,000 principal amount of Senior Convertible Notes in respect of
any such interest period shall equal 0.25% of the average Trading Price for each
$1,000 principal amount of the Senior Convertible Notes for the Applicable Five
Day Trading Period with respect to such interest period. Contingent Interest, if
any, will accrue from May 15 or November 15, as applicable, and will be payable
in the same manner, at the same times and to the same Persons as ordinary
interest. Upon determination that Holders of the Senior Convertible Notes will
be entitled to receive Contingent Interest during an interest period, as
promptly as practicable after such determination, the Corporation shall publish

Interest in a newspaper of general circulation in The City of New York or

Interest) accrued to but excluding the respective Interest Payment Dates,
Redemption Date, Put Date or Fundamental Change Purchase Date, as the case may

Convertible Notes shall be computed and paid on the basis of a 360-day year of
twelve 30-day months. In the event that any date on which interest (including
any Contingent Interest) is payable on the Senior Convertible Notes is not a
Business Day, then payment of the interest (including any Contingent Interest)
payable on such date shall be made on the next succeeding day that is a Business
Day (and without any interest or payment in respect of any such delay) with the
same force and effect as if made on the date the payment was originally payable.

      (d)   Payment of principal of, premium, if any, and interest (including
any Contingent Interest) on the Senior Convertible Notes shall be made in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. Payments of principal of,
premium, if any, and interest (including any Contingent Interest) on Senior
Convertible Notes represented by a Global Security shall be made by wire
transfer of immediately available funds to the Holder of such Global Security,
provided that, in the case of payments of principal and premium, if any, such
Global Security is first surrendered to the Paying Agent. If any of the Senior
Convertible Notes are no longer represented by a Global Security, (i) payments
of principal, premium, if any, and interest (including any Contingent Interest)
due at the Stated Maturity or earlier redemption or purchase of such Senior
Convertible Notes shall be made at the office of the Paying Agent upon surrender
of such Senior Convertible Notes to the Paying Agent and (ii) payments of
interest (including any Contingent Interest) shall be made, at the option of the
Corporation, subject to such surrender where applicable, (A) by check mailed to

banking institution in the United States as may be designated in writing to the
Trustee at least sixteen (16) days prior to the date for payment by the Person
entitled thereto.

      SECTION 1.04 Denominations. The Senior Convertible Notes shall be issued
in denominations of $1,000 and any integral multiple thereof.

      SECTION 1.05 Global Securities. (a) The Senior Convertible Notes shall
initially be issued in the form of one or more Global Securities registered in
the name of the Depositary (which initially shall be The Depository Trust
Company) or its nominee. Except under the limited circumstances described below,
Senior Convertible Notes represented by such Global Security or Global
Securities shall not be exchangeable for, and shall not otherwise be issuable
as, Senior Convertible Notes in definitive form. The Global Securities described
in this Article 1 may not be transferred except by the Depositary to a nominee
of the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or to a successor Depositary or its nominee.

      (b)   A Global Security shall be exchangeable for Senior Convertible Notes
registered in the names of Persons other than the Depositary or its nominee only
if (i) the Depositary notifies the Corporation that it is unwilling or unable to
continue as a Depositary for such Global Security and no successor Depositary
shall have been appointed by the Corporation within 90 days of receipt by the
Corporation of such notification, or if at any time the Depositary ceases to be
a clearing agency registered under the Exchange Act at a time when the
Depositary is required to be so registered to act as such Depositary and no
successor Depositary shall have been appointed by the Corporation within 90 days
after it becomes aware of such cessation or (ii) the Corporation in its sole
discretion determines that such Global Security shall be so exchangeable. Any
Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Senior Convertible Notes registered in such names as the
Depositary shall direct.

      SECTION 1.06 Optional Redemption. (a) On or after May 20, 2007, the Senior
Convertible Notes shall be redeemable, in whole or from time to time in part, at
the option of the Corporation on any date (a "Redemption Date"), at a redemption
price equal to 100% of the principal amount of the Senior Convertible Notes to
be redeemed plus any accrued and unpaid interest (including Contingent Interest,
if any) on the principal amount to be redeemed to but excluding the Redemption
Date (the "Redemption Price").

      (b)   The Corporation shall notify each Holder of the redemption pursuant
to Section 1104 of the Original Indenture.

      (c)   If any Senior Convertible Notes selected for partial redemption are
thereafter surrendered for conversion in part before termination of the
conversion right with respect to the portion of the Senior Convertible Notes so
selected, the converted portion of such Senior Convertible Notes shall be deemed
(so far as may be), solely for purposes of determining the aggregate principal
amount of Senior Convertible Notes to be redeemed by the Corporation, to be the
portion selected for redemption. Senior Convertible Notes which have been
converted during a selection of Senior Convertible Notes to be redeemed may be
treated by the Trustee as Outstanding for the purpose of such selection. Nothing
in this Section 1.06(c) shall affect the right of any Holder to convert any
Senior Convertible Notes before the termination of the conversion right with
respect thereto.

      Section 1.07 only if the Senior Convertible Notes so delivered or
      transferred to the Paying Agent shall conform in all respects to the
      description thereof in the related Fundamental Change Purchase Notice.

      SECTION 1.08 Purchase of Senior Convertible Notes at the Option of the

Senior Convertible Notes in respect of which a Fundamental Change Purchase
Notice or Put Notice, as the case may be, has been given by the Holder thereof
may not be converted for shares of Common Stock on or after the date of the
delivery of such Fundamental Change Purchase Notice or Put Notice, as the case
may be, unless such Fundamental Change Purchase Notice or Put Notice, as the
case may be, has first been validly withdrawn or deemed to have been validly
withdrawn as specified in Section 1.09(c); provided that the Senior Convertible
Notes are otherwise convertible in accordance with the fourth through ninth
paragraphs of the reverse of the Senior Convertible Notes.

      On or before 10:00 a.m. (New York City time) on the Fundamental Change
Purchase Date or the Put Date, as the case may be, the Corporation shall deposit
with the Paying Agent (or if the Corporation or an Affiliate of the Corporation
is acting as the Paying Agent, shall segregate and hold in trust) money
sufficient to pay the aggregate Fundamental Change Purchase Price or the
aggregate Purchase Price, as the case may be, of the Senior Convertible Notes to
be purchased pursuant to Section 1.07 or Section 1.08, as applicable. Payment by
the Paying Agent of such Fundamental Change Purchase Price or Purchase Price for
such Senior Convertible Notes shall be made promptly following the later of the
Fundamental Change Purchase Date or the Put Date, as the case may be, or the
time of book-entry transfer or delivery of such Senior Convertible Notes. If the
Paying Agent holds, in accordance with the terms of the Indenture, money
sufficient to pay the Fundamental Change Purchase Price or Purchase Price, as
the case may be, of such Senior Convertible Notes on the Business Day following
the Fundamental Change Purchase Date or the Put Date, as the case may be, then,
on and after such date, such Senior Convertible Notes shall cease to be
Outstanding and interest (including any Contingent Interest) on such Senior
Convertible Notes shall cease to accrue, whether or not book-entry transfer of
such Senior Convertible Notes is made or such Senior Convertible Notes are
delivered to the Paying Agent, and all other rights of the Holder shall
terminate (other than the right to receive the Fundamental Change Purchase Price
or the Purchase Price, as the case may be, upon delivery or transfer of the
Senior Convertible Notes). Nothing herein shall preclude the Corporation
withholding any tax required by law.

      The Corporation shall require each Paying Agent (other than the Trustee)
to agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of the
Fundamental Change Purchase Price or the Purchase Price, as the case may be, and
shall notify the Trustee of any default by the Corporation in making any such
payment. If the Corporation or an Affiliate of the Corporation acts as Paying
Agent, it shall segregate the money held by it as Paying Agent and hold it as a
separate trust fund. The Corporation at any time may require a Paying Agent to
deliver all money held by it pursuant to this Section 1.09 to the Trustee and to
account for any funds disbursed by the Paying Agent. Upon doing so, the Paying
Agent shall have no further liability for the money delivered to the Trustee.

      All questions as to the validity, eligibility (including time of receipt)
and acceptance of any Senior Convertible Notes for purchase shall be determined
by the Corporation, whose determination shall be final and binding, absent
manifest error.

      (c)   Withdrawal of a Put Notice or Fundamental Change Purchase Notice. A
Put Notice or Fundamental Change Purchase Notice, as the case may be, may be
withdrawn by
<PAGE>
                                                                              14

means of a written notice of withdrawal delivered to the office of the Paying
Agent at any time prior to 5:00 p.m. New York City time on the Business Day
prior to the Put Date or the Fundamental Change Purchase Date, as the case may
be, to which it relates specifying:

            (i)   if certificated, the certificate number of the Senior
      Convertible Notes in respect of which such notice of withdrawal is being
      submitted;

            (ii)  the principal amount of the Senior Convertible Notes with
      respect to which such notice of withdrawal is being submitted; and

            (iii) the principal amount, if any, of such Senior Convertible Notes
      which remains subject to the Put Notice or Fundamental Change Purchase
      Notice, as the case may be, and which has been or shall be transferred or
      delivered for purchase by the Corporation.

      The Paying Agent shall promptly notify the Corporation of the receipt by
it of any Put Notice or Fundamental Change Purchase Notice or written notice of
withdrawal thereof.

      (d)   Notwithstanding the requirements of Sections 1.07 or 1.08 and this
Section 1.09, if the Senior Convertible Notes are represented by Global
Securities in book-entry form the appropriate procedures of the Depositary must
be complied with for any purchase upon a Fundamental Change or Put Option.

      (e)   Effect of Event of Default. There shall be no purchase of any Senior
Convertible Notes pursuant to Section 1.07 or Section 1.08 if an Event of
Default has occurred and is continuing (other than a default that is cured by
the payment of the Purchase Price or Fundamental Change Purchase Price, as the
case may be). The Paying Agent shall promptly return to the respective Holders
thereof any Senior Convertible Notes (x) with respect to which a Put Notice or
Fundamental Change Purchase Notice, as the case may be, has been withdrawn in
compliance with this Twelfth Supplemental Indenture, or (y) held by it during
the continuance of an Event of Default (other than a default that is cured by
the payment of the Purchase Price or Fundamental Change Purchase Price, as the
case may be) in which case, upon such return, the Put Notice or Fundamental
Change Purchase Notice with respect thereto shall be deemed to have been
withdrawn.

      (f)   Senior Convertible Notes Purchased in Part. Any Senior Convertible
Notes that are to be purchased only in part shall be surrendered at the office
of the Paying Agent (with, if the Corporation or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Corporation and the Trustee duly executed by, the Holder thereof or such
Holder's attorney duly authorized in writing) and the Corporation shall execute
and the Trustee or the Authenticating Agent, if any, shall authenticate and
deliver to the Holder of such Senior Convertible Notes, without service charge,
a new Senior Convertible Note or Senior Convertible Notes, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to,
and in exchange for, the portion of the principal amount of the Senior
Convertible Notes so surrendered which is not purchased.

      (g)   Covenant to Comply with Securities Laws Upon Purchase of Senior
Convertible Notes. In connection with any offer to purchase Senior Convertible
Notes under Sections 1.07 or
<PAGE>
                                                                              15

1.08 hereof, the Corporation shall, to the extent applicable, (i) comply with
Rules 13e-4 and 14e-1 (and any successor provisions thereto) under the Exchange
Act, if applicable, (ii) file the related Schedule TO (or any successor
schedule, form or report) under the Exchange Act, if applicable and (iii)
otherwise comply with all applicable federal and state securities laws so as to
permit the rights and obligations under Sections 1.07, 1.08 or this Section 1.09
to be exercised in the manner specified in Sections 1.07, 1.08 or this Section
1.09; provided, however, that the Corporation shall not take any action in
violation of any applicable federal or state securities laws.

      (h)   Repayment to the Corporation. The Trustee and the Paying Agent shall
return to the Corporation any cash or property that remains unclaimed as
provided in Section 1003 of the Original Indenture, together with any unclaimed
interest (including any Contingent Interest, if any), held by them for the
payment of a Purchase Price or Fundamental Change Purchase Price, as the case
may be; provided, however, that to the extent that the aggregate amount of cash
deposited by the Corporation pursuant to Section 1.09(b), as applicable, exceeds
the aggregate Purchase Price or Fundamental Change Purchase Price, as the case
may be, of the Senior Convertible Notes or portions thereof which the
Corporation is obligated to purchase as of the Put Date or Fundamental Change
Purchase Date, as the case may be, then promptly on and after the Business Day
following the Put Date or Fundamental Change Purchase Date, as the case may be,
the Trustee or the Paying Agent, as the case may be, shall return any such
excess to the Corporation together with any excess interest (including any
Contingent Interest, if any) held by them for payment to Holders.

      (i)   In any case where a Put Date or a Fundamental Change Purchase Date
shall not be a Business Day at any Place of Payment, then (notwithstanding any
other provision of the Indenture or the Senior Convertible Notes) payment of
interest (including Contingent Interest, if any) and the Purchase Price or the
Fundamental Change Purchase Price, as the case may be, need not be made at such
Place of Payment on such date (provided that all other conditions therefor have
been complied with), but may be made on the next succeeding Business Day at such
Place of Payment (provided that such conditions have been complied with) with
the same force and effect as if made on the Put Date or the Fundamental Change
Purchase Date, as the case may be (and without any interest or payment in
respect of any such delay).

      SECTION 1.10 Conversion of Senior Convertible Notes.

      (a)   Right to Convert. A Holder may convert its Senior Convertible Notes
for Common Stock at any time during the periods specified in the fourth
paragraph of the reverse of the Senior Convertible Notes.

      (b)   The Conversion Rate. The initial Conversion Rate is 42.3908 shares
of Common Stock issuable upon conversion of $1,000 principal amount of a Senior
Convertible Note (the "Conversion Rate"), subject to adjustment as herein set
forth. A Holder may convert a portion of the principal amount of Senior
Convertible Notes if the portion is $1,000 or an integral multiple thereof.
<PAGE>
                                                                              16

      (c)   Conversion Procedures. To convert Senior Convertible Notes, the
requirements set forth in this Section 1.10(c) and in the fourth through ninth
paragraphs of the reverse of the Senior Convertible Notes must be satisfied.

            (i)   To convert the Senior Convertible Notes, a Holder must (1)
      complete and manually sign the irrevocable conversion notice on the back
      of the Senior Convertible Notes (or complete and manually sign a facsimile
      of such notice) and deliver such notice to the Conversion Agent at the
      office maintained by the Conversion Agent for such purpose, (2) with
      respect to Senior Convertible Notes in certificated form, surrender the
      Notes to the Conversion Agent or with respect to Senior Convertible Notes
      represented by Global Securities, cause the book-entry transfer thereof to
      the Conversion Agent, (3) furnish appropriate endorsements and transfer
      documents if required by the Conversion Agent, the Corporation or the
      Trustee and (4) pay any transfer or similar tax, if required. The date on
      which the Holder satisfies all such requirements is the conversion date
      (the "Conversion Date"). As soon as practicable, but in no event later
      than the fifth Business Day following the Conversion Date, the Corporation
      shall deliver to the Holder, through the Conversion Agent, a certificate
      (or credit the book-entry transfer of such shares of Common Stock) for the
      number of full shares of Common Stock issuable upon the conversion and
      cash in lieu of any fractional share determined pursuant to Section
      1.10(d).

            (ii)  Holders of Senior Convertible Notes at the close of business
      on a Regular Record Date will receive payment of interest (including
      Contingent Interest, if any) payable on the corresponding Interest Payment
      Date notwithstanding the conversion of such Senior Convertible Notes at
      any time after the close of business on such Regular Record Date. Senior
      Convertible Notes surrendered for conversion during the period from the
      close of business on any Regular Record Date to the opening of business on
      the corresponding Interest Payment Date must be accompanied by payment of
      an amount equal to the interest (including Contingent Interest, if any)
      that the Holder is to receive on the Senior Convertible Notes; provided,
      however, that no such payment need be made with respect to Senior
      Convertible Notes in respect of which a Redemption Date or Fundamental
      Change Purchase Date has been set that falls within this period or on such
      Interest Payment Date or to the extent any overdue interest (or Contingent
      Interest, if any) exists at the time of such conversion. Except as
      described above, no payment or adjustment will be made for accrued
      interest on converted Senior Convertible Notes.

            (iii) The Person in whose name the certificate for such shares of
      Common Stock is registered shall be treated as a stockholder of record on
      and after the Conversion Date; provided, however, that no surrender of
      Senior Convertible Notes on any date when the stock transfer books of the
      Corporation shall be closed shall be effective to constitute the Person or
      Persons entitled to receive the shares of Common Stock upon such
      conversion as the record holder or holders of such shares of Common Stock
      on such date, but such surrender shall be effective to constitute the
      Person or Persons entitled to receive such shares of Common Stock as the
      record holder or holders thereof for all purposes at the close of business
      on the next succeeding day on which such stock transfer books are open;
      such conversion shall be at the Conversion Rate in effect on the date that
      such Senior Convertible Notes shall have been surrendered for conversion,
      as if the stock
<PAGE>
                                                                              17

      transfer books of the Corporation had not been closed. Upon conversion of
      Senior Convertible Notes, such Person shall no longer be a Holder of such
      Senior Convertible Notes.

            (iv)  No payment or adjustment shall be made for dividends on or
      other distributions with respect to any Common Stock except as provided in
      Section 1.10(g) or as otherwise provided in the Indenture. If a Holder
      converts more than one Senior Convertible Note at the same time, the
      number of shares of Common Stock issuable upon the conversion shall be
      based on the total principal amount of the Senior Convertible Notes
      converted. Upon surrender of a Senior Convertible Note that is converted
      in part, the Corporation shall execute, and the Trustee or the
      Authenticating Agent shall authenticate and deliver to the Holder, a new
      Senior Convertible Note in an authorized denomination equal in principal
      amount to the unconverted portion of the Senior Convertible Note
      surrendered. If the last day on which Senior Convertible Notes may be
      converted is not a Business Day in a place where a Conversion Agent is
      located, the Senior Convertible Notes may be surrendered to that
      Conversion Agent on the next succeeding day that is a Business Day. A
      Holder of Senior Convertible Notes is not entitled to any rights of a
      holder of Common Stock until such Holder has converted its Senior
      Convertible Notes to Common Stock, and only to the extent such Senior
      Convertible Notes are deemed to have been converted into Common Stock
      pursuant to this Section 1.10.

      (d)   Cash Payments in Lieu of Fractional Shares. The Corporation shall
not issue a fractional share of Common Stock upon conversion of Senior
Convertible Notes. Instead the Corporation shall deliver cash for the current
market value of the fractional share. The current market value of a fractional
share shall be determined to the nearest 1/10,000th of a share by multiplying
the Last Reported Sale Price of a full share of Common Stock on the Trading Day
immediately preceding the Conversion Date by the fractional amount and rounding
the product to the nearest whole cent.

      (e)   Taxes on Conversion. If a Holder converts Senior Convertible Notes,
the Corporation shall pay any documentary, stamp or similar issue or transfer
tax due on the issue of shares of Common Stock upon the conversion. However, the
Holder shall pay any such tax which is due because the Holder requests the
shares to be issued in a name other than the Holder's name. The Conversion Agent
may refuse to deliver the certificates representing the Common Stock being
issued in a name other than the Holder's name until the Conversion Agent
receives a sum sufficient to pay any tax which shall be due because the shares
are to be issued in a name other than the Holder's name. Nothing herein shall
preclude the Corporation's withholding any tax required by law.

      (f)   Covenants of the Corporation. The Corporation shall, prior to
issuance of any Senior Convertible Notes hereunder, and from time to time as may
be necessary, reserve out of its authorized but unissued Common Stock a
sufficient number of shares of Common Stock to permit the conversion of the
Senior Convertible Notes. All shares of Common Stock delivered upon conversion
of the Senior Convertible Notes shall be newly issued shares or treasury shares,
shall be duly and validly issued and fully paid and nonassessable and shall be
free from preemptive rights and free of any lien or adverse claim. The
Corporation shall endeavor
<PAGE>
                                                                              18

promptly to comply with all federal and state securities laws regulating the
order and delivery of shares of Common Stock upon the conversion of Senior
Convertible Notes, if any, and shall cause to have listed or quoted all such
shares of Common Stock on the New York Stock Exchange, or, if not listed
thereon, on each United States national securities exchange or over-the-counter
or other domestic market on which the Common Stock is then listed or quoted.

      (g)   Adjustments to Conversion Rate. The Conversion Rate shall be
adjusted from time to time by the Corporation as follows:

            (i)   In case the Corporation shall pay or make a dividend or other
      distribution on the Common Stock in Common Stock, the Conversion Rate, as
      in effect at the opening of business on the day following the date fixed
      for the determination of stockholders entitled to receive such dividend or
      other distribution, shall be increased by dividing such Conversion Rate by
      a fraction of which the numerator shall be the number of shares of Common
      Stock outstanding at the close of business on the date fixed for such
      determination and the denominator shall be the sum of such number of
      shares and the total number of shares constituting such dividend or other
      distribution, such increase to become effective immediately after the
      opening of business on the day following the date fixed for such
      determination. For the purposes of this Section 1.10(g)(i), the number of
      shares of Common Stock at any time outstanding shall not include shares
      held in treasury by the Corporation but shall include any shares issuable
      in respect of any scrip certificates issued in lieu of fractions of shares
      of Common Stock. The Corporation will not pay any dividend or make any
      distribution on shares of Common Stock held in treasury by the
      Corporation.

            (ii)  In case the Corporation shall issue rights, options or
      warrants to all holders of its Common Stock (not being available on an
      equivalent basis to Holders of the Senior Convertible Notes upon
      conversion of such Senior Convertible Notes) entitling them, for a period
      expiring within 45 days after the record date for the determination of
      stockholders entitled to receive such rights, options or warrants, to
      subscribe for or purchase shares of Common Stock at a price per share less
      than the Current Market Price per share of the Common Stock on the date
      fixed for the determination of stockholders entitled to receive such
      rights, options or warrants (other than pursuant to a dividend
      reinvestment plan or share purchase plan), the Conversion Rate in effect
      at the opening of business on the day following the date fixed for such
      determination shall be increased by dividing such Conversion Rate by a
      fraction of which the numerator shall be the number of shares of Common
      Stock outstanding at the close of business on the date fixed for such
      determination plus the number of shares of Common Stock which the
      aggregate offering price of the total number of shares of Common Stock so
      offered for subscription or purchase would purchase at such Current Market
      Price and the denominator shall be the number of shares of Common Stock
      outstanding at the close of business on the date fixed for such
      determination plus the number of shares of Common Stock so offered for
      subscription or purchase at such below Current Market Price, such increase
      to become effective immediately after the opening of business on the day
      following the date fixed for such determination. For the purposes of this
      Section 1.10(g)(ii), the number of shares of Common Stock at any time
      outstanding shall not include shares held in treasury by the Corporation
      but shall include any shares issuable in respect of any scrip certificates
<PAGE>
                                                                              19

      issued in lieu of fractions of shares of Common Stock. The Corporation
      shall not issue any such rights, options or warrants in respect of shares
      of Common Stock held in treasury by the Corporation.

            (iii) In case outstanding shares of Common Stock shall be subdivided
      or split into a greater number of shares of Common Stock, the Conversion
      Rate in effect at the opening of business on the day following the day
      upon which such subdivision or split becomes effective shall be
      proportionately increased, and, conversely, in case outstanding shares of
      Common Stock shall each be combined into a smaller number of shares of
      Common Stock, the Conversion Rate in effect at the opening of business on
      the day following the day upon which such combination becomes effective
      shall be proportionately reduced, such increase or reduction, as the case
      may be, to become effective immediately after the opening of business on
      the day following the day upon which such subdivision, split or
      combination becomes effective.

            (iv)  In case the Corporation shall, by dividend or otherwise,
      distribute to all holders of its Common Stock evidences of its
      indebtedness, shares of capital stock, securities, cash or other property
      (but excluding any rights, options or warrants referred to in Section
      1.10(g)(ii) of this Section, any dividend or distribution paid exclusively
      in cash and any dividend or distribution referred to in Section
      1.10(g)(i)), the Conversion Rate shall be adjusted by dividing the
      Conversion Rate in effect immediately prior to the close of business on
      the date fixed for the determination of stockholders entitled to receive
      such distribution by a fraction of which the numerator shall be the
      Current Market Price per share of the Common Stock on the date fixed for
      such determination less the then fair market value (as determined by the
      Board of Directors, whose determination shall be conclusive and described
      in a Board Resolution) on such date of the portion of the evidences of
      indebtedness, shares of capital stock, securities, cash or other property
      so distributed applicable to one share of Common Stock and the denominator
      shall be such Current Market Price per share of the Common Stock, such
      adjustment to become effective immediately prior to the opening of
      business on the day following the date fixed for the determination of
      stockholders entitled to receive such distribution; provided, however,
      that in the event that the Corporation makes a distribution to all holders
      of its Common Stock consisting of capital stock of, or similar equity
      interests in, a subsidiary or other business unit of the Corporation, the
      Conversion Rate shall be adjusted by dividing the Conversion Rate in
      effect immediately prior to the close of business on the date fixed for
      the determination of stockholders entitled to receive such distribution by
      a fraction of which the numerator shall be the Spin-off Market Price per
      share of the Common Stock on the date fixed for such determination less
      the Spin-off Market Price per share or similar equity interest of the
      subsidiary or other business unit of the Corporation on such date and the
      denominator shall be the Spin-off Market Price per share of the Common
      Stock, such adjustment to become effective 10 trading days after the
      effective date of such distribution of capital stock of, or similar equity
      interest in, a subsidiary or other business unit of the Corporation. In
      any case in which this Section 1.10(g)(iv) is applicable, Sections
      1.10(g)(i) and (ii) shall not be applicable.

            (v)   In case the Corporation shall, (I) by dividend or otherwise,
      distribute to all holders of its Common Stock cash (excluding (i) any cash
      that is distributed in an event
<PAGE>
                                                                              20

      to which Section 1.10(h)(iv) applies or (ii) cash that is distributed as
      part of a distribution referred to in Section 1.10(g)(iv)) in an aggregate
      amount that, combined together with (II) the aggregate amount of any other
      distributions to all holders of its Common Stock made exclusively in cash
      within the 12 months preceding the date of payment of such distribution
      and in respect of which no adjustment pursuant to this Section 1.10(g)(v)
      or Section 1.10(g)(vi) has been made and (III) the aggregate of any cash
      plus the fair market value, as of the expiration of the applicable tender
      or exchange offer referred to below (as determined by the Board of
      Directors, whose determination shall be conclusive and described in a
      Board Resolution), of consideration payable in respect of any tender or
      exchange offer (other than consideration payable in respect of any odd-lot
      tender offer) by the Corporation or any of its subsidiaries for all or any
      portion of the Common Stock concluded within the 12 months preceding the
      date of payment of the distribution described in clause (I) above and in
      respect of which no adjustment pursuant to this Section 1.10(g)(v) or
      Section 1.10(g)(vi) has been made, exceeds the product of $1.10
      (appropriately adjusted from time to time for any stock dividends on or
      subdivisions or combination of Common Stock) multiplied by the number of
      shares of Common Stock outstanding on such date, then, and in each such
      case, immediately after the close of business on such date for
      determination, the Conversion Rate shall be increased so that the same
      shall equal the rate determined by dividing the Conversion Rate in effect
      immediately prior to the close of business on the date fixed for
      determination of the stockholders entitled to receive such distribution by
      a fraction (i) the numerator of which shall be equal to the Current Market
      Price per share of the Common Stock on the date fixed for such
      determination plus $1.10 (appropriately adjusted from time to time for any
      stock dividends on or subdivisions or combination of Common Stock) less an
      amount equal to the quotient of (x) the combined amount distributed or
      payable in the transactions described in clauses (I), (II) and (III) above
      and (y) the number of shares of Common Stock outstanding on such date for
      determination and (ii) the denominator of which shall be equal to the
      Current Market Price per share of the Common Stock on such date for
      determination.

            (vi)  In case (I) a tender or exchange offer made by the Corporation
      or any subsidiary of the Corporation for all or any portion of the Common
      Stock shall expire and such tender or exchange offer (as amended upon the
      expiration thereof) shall require the payment to stockholders (based on
      the acceptance (up to any maximum specified in the terms of the tender or
      exchange offer) of Purchased Shares) of an aggregate consideration having
      a fair market value (as determined by the Board of Directors, whose
      determination shall be conclusive and described in a Board Resolution)
      that combined together with (II) the aggregate of the cash plus the fair
      market value (as determined by the Board of Directors, whose determination
      shall be conclusive and described in a Board Resolution), as of the
      expiration of such tender or exchange offer, of consideration payable in
      respect of any other tender or exchange offer (other than consideration
      payable in respect of any odd-lot tender offer) by the Corporation or any
      subsidiary of the Corporation for all or any portion of the Common Stock
      expiring within the 12 months preceding the expiration of such tender or
      exchange offer and in respect of which no adjustment pursuant to Section
      1.10(g)(v) or this Section 1.10(g)(vi) has been made and (III) the
      aggregate amount of any distributions to all holders of the Corporation's
      Common Stock made exclusively in cash within the 12 months preceding the
      expiration of such tender or
<PAGE>
                                                                              21

      exchange offer and in respect of which no adjustment pursuant to Section
      1.10(g)(v) or this Section 1.10(g)(vi) has been made, exceeds the product
      of $1.10 (appropriately adjusted from time to time for any stock dividends
      on or subdivisions or combination of Common Stock) multiplied by the
      number of shares of Common Stock outstanding (including any tendered
      shares) as of the last time (the "Expiration Time") tenders could have
      been made pursuant to such tender or exchange offer (as it may be
      amended), then, and in each such case, immediately prior to the opening of
      business on the day after the date of the Expiration Time, the Conversion
      Rate shall be adjusted so that the same shall equal the rate determined by
      dividing the Conversion Rate immediately prior to the close of business as
      of the Expiration Time by a fraction (i) the numerator of which shall be
      equal to (A) the product of (1) the Current Market Price per share of the
      Common Stock as of the Expiration Time plus $1.10 (appropriately adjusted
      from time to time for any stock dividends on or subdivisions or
      combination of Common Stock) and (2) the number of shares of Common Stock
      outstanding (including any tendered shares) as of the Expiration Time less
      (B) the amount of cash plus the fair market value (determined as
      aforesaid) of the aggregate consideration payable to stockholders based on
      the transactions described in clauses (I), (II) and (III) above (assuming
      in the case of clause (I) the acceptance, up to any maximum specified in
      the terms of the tender or exchange offer, of Purchased Shares), and (ii)
      the denominator of which shall be equal to the product of (A) the Current
      Market Price per share of the Common Stock as of the Expiration Time and
      (B) the number of shares of Common Stock outstanding (including any
      tendered shares) as of the Expiration Time less the number of all shares
      validly tendered and not withdrawn as of the Expiration Time (the shares
      deemed so accepted, up to any such maximum, being referred to as the
      "Purchased Shares").

            (vii) The reclassification of Common Stock into securities including
      securities other than Common Stock (other than any reclassification upon
      an event to which Section 1.10(h)(iv) applies) shall be deemed to involve
      (a) a distribution of such securities other than Common Stock to all
      holders of Common Stock (and the effective date of such reclassification
      shall be deemed to be "the date fixed for the determination of
      stockholders entitled to receive such distribution" and the "date fixed
      for such determination" within the meaning of Section 1.10(g)(iv)), and
      (b) a subdivision, split or combination, as the case may be, of the number
      of shares of Common Stock outstanding immediately prior to such
      reclassification into the number of shares of Common Stock outstanding
      immediately thereafter (and the effective date of such reclassification
      shall be deemed to be "the day upon which such subdivision or split
      becomes effective" or "the day upon which such combination becomes
      effective," as the case may be, and "the day upon which such subdivision,
      split or combination becomes effective" within the meaning of Section
      1.10(g)(iii)).

            (viii)  All adjustments to the Conversion Rate, shall be calculated
      to the nearest 1/10,000th of a share of Common Stock (or if there is not a
      nearest 1/10,000th of a share to the next lower 1/10,000th of a share). No
      adjustment in the Conversion Rate shall be required unless such adjustment
      would require an increase or decrease of at least one percent therein;
      provided, however, that any adjustments which by reason of this
      subparagraph are not required to be made shall be carried forward and
      taken into account in any subsequent adjustment.

                                                                              22

                  (ix)     Notwithstanding the foregoing provisions of Section
         1.10(g)(ii) or (iv), no adjustment shall be made thereunder, nor shall
         an adjustment be made to the ability of a Holder of a Note to convert,
         for any distribution described therein if the Holder will otherwise
         participate in the distribution without conversion of such Holder's
         Senior Convertible Notes.

                  (x)      No adjustment pursuant to the Conversion Rate or a
         holder's ability to convert pursuant to this Section 1.10(g) shall be
         made in connection with the issuance of rights, the distribution of
         separate certificates representing rights or the exercise, redemption,
         termination or invalidation of rights pursuant to any stockholder
         rights plan implemented by the Corporation which provides that, upon
         conversion of the Senior Convertible Notes, the Holders shall receive,
         in addition to the Common Stock issuable upon such conversion, the
         rights issued under such stockholder rights plan (notwithstanding the
         occurrence of an event causing such rights to separate from the Common
         Stock at or prior to the time of conversion).

         (h)      Miscellaneous Provisions Relating to Conversion.

                  (i)      When No Adjustment Required. No adjustment to the
         Conversion Rate need be made:

                           (1)      upon the issuance of any shares of Common
                  Stock pursuant to any present or future plan providing for the
                  reinvestment of dividends or interest payable on securities of
                  the Corporation and the investment of additional optional
                  amounts in shares of Common Stock under any plan;

                           (2)      upon the issuance of any shares of Common
                  Stock or options or rights to purchase those shares pursuant
                  to any present or future employee, director or consultant
                  benefit plan or program of or assumed by the Corporation or
                  any of its Subsidiaries;

                           (3)      upon the issuance of any shares of Common
                  Stock pursuant to any option, warrant, right, or exercisable,
                  exchangeable or convertible security not described in (2)
                  above and outstanding as of the date the Senior Convertible
                  Notes were first issued;

                           (4)      for a change in the par value of the Common
                  Stock; or

                           (5)      for accrued and unpaid interest, including
                  Contingent Interest, if any.

         To the extent the Senior Convertible Notes become convertible into
         cash, assets or property (other than capital stock of the Corporation
         or securities to which Section 1.10(h)(iv) applies), no adjustment
         shall be made thereafter as to the cash, assets or property. Interest
         shall not accrue on such cash, assets or property.

                  (ii)     Notice of Adjustment. Whenever the Conversion Rate is
         adjusted, the Corporation shall promptly mail to Holders a notice of
         the adjustment. The Corporation
<PAGE>
                                                                              23

         shall file with the Trustee and the Conversion Agent such notice. The
         certificate shall, absent manifest error, be conclusive evidence that
         the adjustment is correct. Neither the Trustee nor any Conversion Agent
         shall be under any duty or responsibility with respect to any such
         certificate except to exhibit the same to any Holder desiring
         inspection thereof.

                  (iii)    Voluntary Increase. The Corporation may make such
         increases in the Conversion Rate, in addition to those required by
         Section 1.10(g), as the Board of Directors considers to be advisable to
         avoid or diminish any income tax to holders of Common Stock or rights
         to purchase Common Stock resulting from any dividend or distribution of
         stock (or rights to acquire stock) or from any event treated as such
         for income tax purposes. To the extent permitted by applicable law, the
         Corporation may from time to time increase the Conversion Rate by any
         amount for any period of time if the period is at least 20 days, the
         increase is irrevocable during the period and the Board of Directors
         shall have made a determination that such increase would be in the best
         interests of the Corporation, which determination shall be conclusive.
         Whenever the Conversion Rate is so increased, the Corporation shall
         mail to Holders and file with the Trustee and the Conversion Agent a
         notice of such increase. Neither the Trustee nor any Conversion Agent
         shall be under any duty or responsibility with respect to any such
         notice except to exhibit the same to any Holder desiring inspection
         thereof. The Corporation shall mail the notice at least 15 days before
         the date the increased Conversion Rate takes affect. The notice shall
         state the increased Conversion Rate and the period it shall be in
         effect.

                  (iv)     Effect of Reclassification, Consolidation, Merger,
         Binding Share Exchange or Sale. If any of the following events occur,
         namely (a) any reclassification or change of outstanding shares of
         Common Stock (other than a change in par value, or from par value to no
         par value, or from no par value to par value, or as a result of a
         subdivision or combination), (b) any consolidation, merger or binding
         share exchange of the Corporation with another corporation as a result
         of which holders of Common Stock shall be entitled to receive stock,
         securities or other property or assets (including cash) with respect to
         or in exchange for such Common Stock or (c) any sale or conveyance of
         all or substantially all of the assets of the Corporation to any other
         corporation as a result of which holders of Common Stock shall be
         entitled to receive stock, securities or other property or assets
         (including cash) with respect to or in exchange for such Common Stock,
         then the Conversion Rate will not be adjusted. If any of the events
         described in the preceding sentence occur, the Corporation or the
         successor or purchasing corporation, as the case may be, shall execute
         with the Trustee a supplemental indenture or otherwise amend the terms
         of the Senior Convertible Notes, to provide that each Senior
         Convertible Note shall be convertible into the kind and amount of
         shares of stock, other securities or property or assets (including
         cash) that the Holder of the Senior Convertible Note would have
         received upon such reclassification, change, consolidation, merger,
         binding share exchange, sale or conveyance if such Holder had converted
         such Senior Convertible Note into the number of shares of Common Stock
         issuable upon conversion of such Senior Convertible Note immediately
         prior to such reclassification, change, consolidation, merger,
         combination, binding share exchange, sale or conveyance. Such
         supplemental indenture or other amendment to the Senior Convertible
         Notes shall provide for
<PAGE>
                                                                              24

         adjustments which shall be as nearly equivalent as may be practicable
         to the adjustments provided for in this Section 1.10(h)(iv). The
         Corporation shall cause notice of the execution of such supplemental
         indenture or amendment of the Senior Convertible Notes to be mailed to
         each Holder, at its address appearing on the Senior Convertible Note
         register, within 20 days after execution thereof. Failure to deliver
         such notice shall not affect the legality or validity of such
         supplemental indenture. The above provisions of this Section shall
         similarly apply to successive reclassifications, changes,
         consolidations, mergers, combinations, binding share exchanges, sales
         and conveyances. If this Section 1.10(h)(iv) applies to any event or
         occurrence, Section 1.10(g) shall not apply.

                  (v)      Responsibility of Trustee. The Trustee and any other
         Conversion Agent shall not at any time be under any duty or
         responsibility to any Holder to either calculate the Conversion Rate or
         determine whether any facts exist which may require any adjustment of
         the Conversion Rate, or with respect to the nature or extent or
         calculation of any such adjustment when made, or with respect to the
         method employed herein, or in any supplemental indenture provided to be
         employed, in making the same and shall be protected in relying upon an
         Officers' Certificate with respect to the same. The Trustee and any
         other Conversion Agent shall not be accountable with respect to the
         validity or value (or the kind or amount) of any shares of Common
         Stock, or of any securities or property, which may at any time be
         issued or delivered upon the conversion of any Senior Convertible Notes
         and the Trustee and any other Conversion Agent make no representations
         with respect thereto. Neither the Trustee nor any Conversion Agent
         shall be responsible for any failure of the Corporation to issue,
         transfer or deliver any shares of Common Stock or stock certificates or
         other securities or property or cash upon the surrender of any Senior
         Convertible Notes for the purpose of conversion or to comply with any
         of the duties, responsibilities or covenants of the Corporation
         contained in this Section 1.10. Without limiting the generality of the
         foregoing, neither the Trustee nor any Conversion Agent shall be under
         any responsibility to determine the correctness of any provisions
         contained in any supplemental indenture entered into pursuant to
         Section 1.10(h)(iv) relating either to the kind or amount of shares of
         stock or securities or other property or assets (including cash)
         receivable by Holders upon the conversion of their Senior Convertible
         Notes after any event referred to in such Section 1.10(h)(iv) or to any
         adjustment to be made with respect thereto, but, subject to the
         provisions of Article Six of the Indenture, may accept as conclusive
         evidence of the correctness of any such provisions, and shall be
         protected in relying upon, the Officers' Certificate (which the
         Corporation shall be obligated to file with the Trustee prior to the
         execution of any such supplemental indenture) with respect thereto.
         Neither the Trustee nor the Conversion Agent shall be responsible for
         determining whether any event contemplated by the fourth paragraph of
         the reverse of the Senior Convertible Notes has occurred which makes
         the Senior Convertible Notes eligible for conversion or no longer
         eligible therefor until the Corporation has delivered to the Trustee
         and the Conversion Agent an Officers' Certificate stating that such
         event has occurred, on which Certificate the Trustee and the Conversion
         Agent may conclusively rely, and the Corporation agrees to deliver such
         Officers' Certificate to the Trustee and the Conversion Agent
         immediately after the occurrence of any such event.

                                                                              25

                  (vi)     Successive Adjustments. After an adjustment to the
         Conversion Rate under Section 1.10(g), any subsequent event requiring
         an adjustment under Section 1.10(g) shall cause an adjustment to the
         Conversion Rate as so adjusted.

                  (vii)    General Considerations. Whenever successive
         adjustments to the Conversion Rate are called for pursuant to Sections
         1.10(g) or 1.10(h), such adjustments shall be made to the Current
         Market Price as may be necessary or appropriate to effectuate the
         intent of 1.10(g) or 1.10(h) and to avoid unjust or inequitable results
         as determined in good faith by the Board of Directors.

         (i)      On conversion of a Senior Convertible Note, that portion of
accrued and unpaid interest, including Contingent Interest, if any, on the
converted Senior Convertible Note attributable to the period from the most
recent Interest Payment Date (or, if no Interest Payment Date has occurred, from
the Original Issue Date) through the Conversion Date and Tax Original Issue
Discount accrued through the Conversion Date with respect to the converted
Senior Convertible Note shall not be cancelled, extinguished or forfeited, but
rather shall be deemed to be paid in full to the Holder thereof through delivery
of the Common Stock (together with any cash payment in lieu of fractional
shares) in exchange for the Senior Convertible Note being converted pursuant to
the provisions hereof, and the fair market value of such shares of Common Stock
(together with any such cash payment in lieu of fractional shares) shall be
treated as issued, to the extent thereof, first in exchange for accrued and
unpaid interest (including Contingent Interest, if any) and Tax Original Issue
Discount accrued through the Conversion Date and the balance, if any, of such
fair market value of such Common Stock (and any such cash payment), shall be
treated as issued in exchange for the principal amount of the Senior Convertible
Note being converted pursuant to the provisions hereof.

         SECTION 1.11 Additional Events of Default. In addition to those matters
set forth in Section 501 of the Original Indenture, an "Event of Default" with
respect to the Senior Convertible Notes shall also mean any of the following
events:

                  (i)      default in the payment of any interest, including
         Contingent Interest, upon the Senior Convertible Notes when it becomes
         due and payable, and continuance of such default for a period of 60
         days; or

                  (ii)     default in the payment of the principal of on the
         Senior Convertible Notes, at their Maturity, including pursuant to the
         Corporation's obligation to repurchase Senior Convertible Notes upon
         the occurrence of a Fundamental Change pursuant to Section 1.07 or upon
         the exercise by a holder of its option to require the Corporation to
         repurchase such holder's Senior Convertible Notes pursuant to Section
         1.08; or

                  (iii)    default in the Corporation's obligation to convert
         the Senior Convertible Notes upon exercise of a Holder's conversion
         right.

         SECTION 1.12 Amendments; Waiver. In addition to those matters set forth
in Section 902 of the Original Indenture, with respect to the Senior Convertible
Notes, no amendment or supplemental indenture shall without the consent of the
Holder of each Senior Convertible Note affected thereby:
<PAGE>
                                                                              26

                  (i)      reduce the Redemption Price, Purchase Price or
         Fundamental Change Purchase Price of the Senior Convertible Notes; or

                  (ii)     make any change that adversely affects the Holders'
         right to convert the Senior Convertible Notes in accordance with their
         terms and Indenture.

In addition, with respect to the Senior Convertible Notes, to the extent set
forth in Section 513 of the Original Indenture, the Holders of at least a
majority in aggregate principal amount of the Outstanding Senior Convertible
Notes may waive an existing default other than: (I) any default by the
Corporation in any payment of the Redemption Price, Purchase Price or
Fundamental Change Purchase Price with respect to any Senior Convertible Notes,
or (II) any default which constitutes a failure to convert any Senior
Convertible Note in accordance with its terms and the Indenture.

         SECTION 1.13 Register of Securities; Paying Agent; Conversion Agent.
Initially, the Trustee shall act as Paying Agent, Conversion Agent and Security
Registrar with respect to the Senior Convertible Notes with the Place of Payment
for the Senior Convertible Notes initially being the Corporate Trust Office. The
Corporation may appoint and change any Paying Agent, Conversion Agent, Security
Registrar or co-registrar or approve a change in the office through which any
Paying Agent acts without notice, other than notice to the Trustee. The
Corporation or any of its Subsidiaries or any of their Affiliates may act as
Paying Agent, Conversion Agent, Security Registrar or co-registrar.

         SECTION 1.14 Calculations in Respect of the Senior Convertible Notes.
The Corporation will be responsible for making all calculations called for under
the Senior Convertible Notes. These calculations include, but are not limited
to, determination of the Trading Price, Current Market Price, Last Reported Sale
Price, Spin-off Market Price, accrued interest payable (including any Contingent
Interest) on the Senior Convertible Notes and Conversion Rate of the Senior
Convertible Notes. The Corporation will make these calculations in good faith
and, absent manifest error, these calculations will be final and binding on the
Holders. Promptly after the calculation thereof, the Corporation will provide to
each of the Trustee and the Conversion Agent an Officers' Certificate setting
forth a schedule of its calculations and each of the Trustee and the Conversion
Agent is entitled to conclusively rely upon the accuracy of such calculations
without independent verification; provided, however, that in connection with the
Corporation's obligation to pay Contingent Interest under Section 1.03(b)
hereof, the Corporation shall determine whether Contingent Interest is payable
with respect to an interest period and shall deliver to the Trustee and the
Paying Agent no later than the first Business Day of each interest period with
respect to which it has determined that Contingent Interest is payable an
Officers' Certificate evidencing such determination, setting forth the
calculations on which such determination is based and setting forth the amount
of interest (including Contingent Interest) which will accrue on the Senior
Convertible Notes during such interest period. The Trustee and the Paying Agent
may conclusively rely on such Officers' Certificate and may conclusively assume
that no Contingent Interest is payable for any interest period for which they
have not received such Officers' Certificate. The Trustee and the Paying Agent
shall not be responsible for making any calculation or determination referred to
in this Section 1.14. The Trustee will forward the Corporation's calculations to
any Holder upon the request of such Holder.

                                                                              27

         SECTION 1.15 Tax Treatment. The Corporation agrees, and by acceptance
of beneficial ownership interest in the Senior Convertible Notes each beneficial
holder of Senior Convertible Notes will be deemed to have agreed, for United
States federal income tax purposes (1) to treat the Senior Convertible Notes as
indebtedness that is subject to Treas. Reg. Sec. 1.1275-4 (the "Contingent
Payment Regulations") and, for purposes of the Contingent Payment Regulations,
to treat the fair market value of any stock beneficially received by a
beneficial holder upon any conversion of the Senior Convertible Notes as a
contingent payment and (2) to be bound by the Corporation's determination of the
"comparable yield" and "projected payment schedule," within the meaning of the
Contingent Payment Regulations, with respect to the Senior Convertible Notes. A
Holder of Senior Convertible Notes may obtain the issue price, the amount of
original issue discount, issue date, yield to maturity, comparable yield and

         Duke Energy Corporation, a North Carolina corporation (the
"Corporation," which term includes any successor corporation under the Indenture
referred to on the reverse hereof), for value received, hereby promises to pay
to               , or registered assigns, the principal sum of          DOLLARS
($       ) on the Stated Maturity shown above and to pay interest thereon from
the Original Issue Date shown above, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, semi-annually in
arrears on each Interest Payment Date as specified above, commencing on November
15, 2003 and on the Stated Maturity at the rate per annum shown above (the
"Interest Rate") until the principal hereof is paid or made available for
payment and on any overdue principal and on any overdue installment of interest,
together with any Contingent Interest. The interest (including Contingent
Interest, if any) so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the Person
in whose name this 1-3/4% Convertible Senior Note due 2023 (this "Security") is
registered on the Regular Record Date as specified above next preceding such
Interest Payment Date. Except as otherwise provided in the Indenture, any such
interest, including any Contingent Interest, not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange, if any, on which
the Securities shall be listed, and upon such notice as may be required by any
such exchange, all as more fully provided in the Indenture.

         Payments of interest (including Contingent Interest, if any) on this
Security will include interest accrued (including Contingent Interest, if any)
to but excluding the respective Interest Payment Dates. Payments of interest
(including Contingent Interest, if any) for this Security shall be computed and
paid on the basis of a 360-day year consisting of twelve 30-day months and will
accrue from May 7, 2003 or from the most recent Interest Payment Date to which
interest has been paid or duly provided for. In the event that any date on which
interest (including Contingent Interest, if any) is payable on this Security is
not a Business Day, then payment of the interest (including Contingent Interest,
if any) payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or payment in respect of any such delay)
with the same force and effect as if made on the date the payment was originally
payable. "Business Day" means any day, other than a Saturday or Sunday, that is
neither a legal holiday nor a day on which commercial banks are authorized or
required by law, regulation or executive order to close in The City of New York.

         Payment of principal of and interest (including Contingent Interest, if
any) on the Securities shall be made in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts. Payments of principal of and interest (including
Contingent Interest, if any) on the Securities of this series represented by a
Global Security shall be made by wire transfer of immediately available funds to
the Holder of such Global Security, provided that, in the case of payments of
principal such Global Security is first surrendered to the Paying Agent. If any
of the Securities of this series are no longer represented by a Global Security,
(i) payments of principal and interest (including Contingent Interest, if any)
due at the Stated Maturity or earlier redemption or purchase of such Securities

                                      A-2
<PAGE>
shall be made at the office of the Paying Agent upon surrender of such
Securities to the Paying Agent, and (ii) payments of interest shall be made, at
the option of the Corporation, subject to such surrender where applicable, (A)
by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or (B) by wire transfer at such place and
to such account at a banking institution in the United States as may be
designated in writing to the Trustee at least sixteen (16) days prior to the
date for payment by the Person entitled thereto.

         The Securities of this series shall be redeemable, in whole or from
time to time in part, at the option of the Corporation on any date on or after
May 20, 2007 (a "Redemption Date"), at a Redemption Price equal to 100% of the
principal amount of the Securities of this series to be redeemed plus any
accrued and unpaid interest (including Contingent Interest, if any) on the
principal amount to be redeemed to but excluding the Redemption Date.

         Notice of any redemption by the Corporation will be mailed at least 30
days but not more than 60 days before any Redemption Date to each Holder of
Securities of this series to be redeemed. If Notice of a redemption is provided
and funds are deposited as required, interest will cease to accrue on and after
the Redemption Date on the Securities of this series or portions of Securities
of this series called for redemption. In the event that any Redemption Date is
not a Business Day, the Corporation will pay the Redemption Price on the next
Business Day without any additional interest or other payment due. If less than
all the Securities of this series are to be redeemed at the option of the
Corporation, the Trustee shall select, in such manner as it shall deem fair and
appropriate, the Securities of this series to be redeemed in whole or in part.
The Trustee may select for redemption Securities of this series and portions of
the Securities of this series in amounts of whole multiples of $1,000.

         A Holder shall have the option to require the Corporation to purchase
any or all of the Securities of this series held by such Holder on May 15, 2007,
May 15, 2012 and May 15, 2017 (each, a "Put Date") at a purchase price (the
"Purchase Price") equal to the principal amount of the Securities of this series
to be purchased plus any accrued and unpaid interest (including Contingent
Interest, if any) to but excluding the Put Date, upon delivery of a Put Notice
containing the information set forth in the Indenture, from the opening of
business on the date that is 20 Business Days prior to such Put Date until the
close of business on the fifth Business Day prior to such Put Date and upon
delivery of the Securities of this series to the Paying Agent by the Holder as
set forth in the Indenture.

         If a Fundamental Change shall occur at any time prior to Stated
Maturity, each Holder shall have the right, at such Holder's option and subject
to the terms and conditions of the Indenture, to require the Corporation to
purchase any or all of such Holder's Securities of this series or any portion of
the principal amount thereof that is equal to $1,000 or an integral multiple of
$1,000 on the day that is 30 days after the date of the Corporation Purchase
Notice of the occurrence of the Fundamental Change (subject to extension to
comply with applicable law) for a Fundamental Change Purchase Price equal to the
principal amount of Securities of this series purchased plus accrued and unpaid
interest (including Contingent Interest, if any) to the Fundamental Change
Purchase Date upon delivery of a Fundamental Change Purchase Notice containing
the information set forth in the Indenture.

                                      A-3
<PAGE>
         Holders have the right to withdraw any Put Notice or Fundamental Change
Purchase Notice, as the case may be, by delivery to the Paying Agent of a
written notice of withdrawal in accordance with the provisions of the Indenture.

         If cash sufficient to pay a Fundamental Change Purchase Price or
Purchase Price, as the case may be, of all Securities of this series or portions
thereof to be purchased as of the Fundamental Change Purchase Date or the Put
Date, as the case may be, is deposited with the Paying Agent on the Business Day
following the Fundamental Change Purchase Date or the Put Date, as the case may
be, interest shall cease to accrue on such Securities of this series (or
portions thereof) on and after such date, and the Holder thereof shall have no
other rights as such (other than the right to receive the Fundamental Change
Purchase Price or Purchase Price, as the case may be, upon surrender of such
Note).

         In the event of redemption or purchase of this Security in part only, a
new Security or Securities of this series and of like tenor for the unredeemed
or unpurchased portion hereof will be issued in the name of the Holder hereof
upon the surrender hereof.

         The Securities of this series shall not have a sinking fund.

         The Securities of this series shall constitute the direct unsecured and
unsubordinated debt obligations of the Corporation and shall rank equally in
priority with the Corporation's existing and future unsecured and unsubordinated
indebtedness.

         REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

         Unless the certificate of authentication hereon has been executed by
the Trustee by manual signature, this Security shall not be entitled to any
benefit under the Indenture or be valid or obligatory for any purpose.

                           (Reverse Side of Security)

         This 1-3/4% Convertible Senior Note due 2023 is one of a duly
authorized issue of Securities of the Corporation (the "Securities"), issued and
issuable in one or more series under a Senior Indenture, dated as of September
1, 1998, as supplemented (the "Indenture"), between the Corporation and JPMorgan
Chase Bank (formerly known as The Chase Manhattan Bank), as Trustee (the
"Trustee," which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitation of rights, duties and
immunities thereunder of the Corporation, the Trustee and the Holders of the
Securities issued thereunder and of the terms upon which said Securities are,
and are to be, authenticated and delivered. This Security is one of the series
designated on the face hereof as 1-3/4% Convertible Senior Note due 2023
initially in the aggregate principal amount of $700,000,000 (plus up to an
additional $70,000,000 principal amount upon exercise by the Underwriters of
their over-allotment option pursuant to the Underwriting Agreement). Capitalized
terms used herein for which no definition is provided herein shall have the
meanings set forth in the Indenture.

         The Corporation shall pay Contingent Interest in cash to the Holders of
the Securities of this series in respect of any six-month period from May 15 to
November 14 and from November 15 to May 14, commencing with the six-month period
beginning May 15, 2007, if the average Trading Price for each $1,000 principal
amount of the Securities of this series for the Applicable Five Trading Day
Period with respect to such interest period equals 120% or more of such
principal amount of the Securities of this series. The amount of Contingent
Interest payable per $1,000 principal amount of Securities of this series in
respect of any interest period shall equal 0.25% of the average Trading Price
for each $1,000 principal amount of the Securities of this series for the
Applicable Five Day Trading Period with respect to such interest period.
Contingent Interest, if any, will accrue from May 15 or November 15, as
applicable, and will be payable in the same manner, at the same times and to the
same Persons as ordinary interest. All payments of Contingent Interest shall be
made in cash.

         Upon determination that Holders of the Securities of this series will
be entitled to receive Contingent Interest during an interest period, as
promptly as practicable after such determination, the Corporation shall publish
a notice containing such information with respect to the payment of Contingent
Interest in a newspaper of general circulation in The City of New York or
publish such information on its web site or through such other public medium as
the Corporation may use at that time.

         Subject to the procedures set forth in the Indenture, a Holder may
convert Securities of this series into Common Stock of the Corporation on or
before the close of business on May 14, 2023 during the periods and upon
satisfaction of at least one of the conditions set forth below:

                  (a) in any calendar quarter after the quarter ended June 30,
         2003 (and only during such calendar quarter) if the Last Reported Sale
         Price for the Common Stock for at least 20 Trading Days during the
         period of 30 consecutive Trading Days ending on the last Trading Day of
         the previous calendar quarter equals or exceeds 120% of the Conversion
         Price on such last Trading Day;

                                      A-6
<PAGE>
                  (b) in the event that the Corporation calls any Securities of
         this series for redemption, at any time prior to the close of business
         on the second Business Day immediately preceding the Redemption Date;

                  (c) if the Corporation (1) elects to (A) distribute to all
         holders of Common Stock rights entitling them to purchase, for a period
         expiring within 45 days after the date of such distribution, shares of
         Common Stock at less than the Last Reported Sale Price on the Trading
         Day immediately preceding the declaration date of such distribution or
         (B) distribute to all holders of Common Stock assets, debt securities
         or rights to purchase securities of the Corporation, which distribution
         has a per share value as determined by the Corporation's Board of
         Directors and set forth in a Board Resolution exceeding 15% of the Last
         Reported Sale Price of the Common Stock on the Trading Day immediately
         preceding the declaration date for such distribution. In the case of
         the foregoing clauses (A) and (B), the Corporation must notify the
         Holders of the Securities of this series at least 20 Business Days
         prior to the ex-dividend date for such distribution. Once the
         Corporation has given such notice, Holders of the Securities of this
         series may surrender such Securities for conversion at any time
         thereafter until the earlier of the close of business on the Business
         Day prior to the ex-dividend date or the Corporation's announcement
         that such distribution will not take place. Notwithstanding the
         foregoing, a Holder of the Securities of this series may not exercise
         the foregoing right to convert if the Holder may participate in the
         distribution without converting its Securities. As used herein, the
         term "ex date," when used with respect to any issuance or distribution,
         shall mean the first date on which the Common Stock trades regular way
         on such exchange or in such market without the right to receive such
         issuance or distribution; or (2) in the event that the Corporation
         becomes a party to a consolidation, merger or binding share exchange
         pursuant to which the Common Stock would be converted into cash or
         property (other than securities), at any time from and after the date
         which is 15 days prior to the anticipated effective date of the
         transaction until 15 days after the actual effective date of such
         transaction; or

                  (d) during any period that (1) the long-term credit rating
         assigned to the Securities of this series by both Moody's Investors
         Service, Inc. and Standard & Poor's Ratings Services is lower than Baa3
         and BBB-, respectively; (2) both Moody's Investors Service, Inc. and
         Standard & Poor's Ratings Services no longer rate the Securities of
         this series or have withdrawn their ratings with respect to the
         Securities of this series; or (3) either Moody's Investors Service,
         Inc. or Standard & Poor's Ratings Services no longer rates the
         Securities of this series or has withdrawn or suspended such rating and
         the remaining rating is lower than Baa3 or BBB-, as applicable
         (references to Moody's Investors Service, Inc. and Standard & Poor's
         Ratings Services include any successors to those entities).

         Securities of this series in respect of which a Holder has delivered a
notice of exercise of the option to require the Corporation to purchase such
Securities of this series may be converted only if the notice of exercise is
withdrawn in accordance with the terms of the Indenture.

         The initial Conversion Rate is 42.3908 shares of Common Stock per
$1,000 principal amount, subject to adjustment in certain events described in
the Indenture. The Corporation shall

                                      A-7
<PAGE>
deliver cash or a check in lieu of any fractional share of Common Stock.

         Holders of Securities of this series at the close of business on a
Regular Record Date will receive payment of interest payable on the
corresponding Interest Payment Date notwithstanding the conversion of such
Securities of this series at any time after the close of business on such
Regular Record Date. Securities of this series surrendered for conversion during
the period from the close of business on any Regular Record Date to the opening
of business on the corresponding Interest Payment Date must be accompanied by
payment of an amount equal to the interest that the Holder is to receive on the
Securities of this series (except with respect to Securities of this series in
respect of which a Redemption Date or Fundamental Change Purchase Date has been
set that falls within this period or on such Interest Payment Date or to the
extent any overdue interest (or Contingent Interest, if any) exists at the time
of such conversion). Except as described above, no payment or adjustment will be
made for accrued interest on converted Securities of this series.

         To convert the Securities of this series a Holder must (1) complete and
manually sign the irrevocable conversion notice on the back of the Securities of
this series (or complete and manually sign a facsimile of such notice) and
deliver such notice to the Conversion Agent at the office maintained by the
Conversion Agent for such purpose, (2) surrender the Securities of this series
to the Conversion Agent, (3) furnish appropriate endorsements and transfer
documents if required by the Conversion Agent, the Corporation or the Trustee
and (4) pay any transfer or similar tax, if required.

         A Holder may convert a portion of the Securities of this series only if
the principal amount of such portion is $1,000 or an integral multiple of
$1,000. No payment or adjustment shall be made for dividends on the Common Stock
except as provided in the Indenture. On conversion of Securities of this series,
that portion of accrued and unpaid interest, including Contingent Interest, if
any, on such Securities attributable to the period from the most recent Interest
Payment Date (or, if no Interest Payment Date has occurred, from the Original
Issue Date) through the Conversion Date and Tax Original Issue Discount accrued
through the Conversion Date with respect to such converted Securities shall not
be cancelled, extinguished or forfeited, but rather shall be deemed to be paid
in full to the Holder thereof through delivery of the Common Stock (together
with any cash payment in lieu of fractional shares) in exchange for such
Securities being converted pursuant to the provisions hereof, and the fair
market value of such shares of Common Stock (together with any such cash payment
in lieu of fractional shares) shall be treated as issued, to the extent thereof,
first in exchange for accrued and unpaid interest (including Contingent
Interest, if any) and Tax Original Issue Discount accrued through the Conversion
Date and the balance, if any, of such fair market value of such Common Stock
(and any such cash payment), shall be treated as issued in exchange for the
principal amount of such Securities being converted pursuant to the provisions
hereof.

         If an Event of Default with respect to the Securities of this series
shall occur and be continuing, the principal of the Securities of this series
may be declared due and payable in the manner, with the effect and subject to
the conditions provided in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Corporation and the rights of the

                                      A-8
<PAGE>
Holders of the Securities of all series affected under the Indenture at any time
by the Corporation and the Trustee with the consent of the Holders of not less
than a majority in principal amount of the Outstanding Securities of all series
affected thereby (voting as one class). The Indenture contains provisions
permitting the Holders of not less than a majority in principal amount of the
Outstanding Securities of all series with respect to which a default under the
Indenture shall have occurred and be continuing (voting as one class), on behalf
of the Holders of the Securities of all such series, to waive, with certain
exceptions, such default under the Indenture and its consequences. The Indenture
also permits the Holders of not less than a majority in principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Corporation with
certain provisions of the Indenture affecting such series. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Corporation,
which is absolute and unconditional, to pay the principal of and interest on
this Security at the times, place and rate, and in the coin or currency, herein
prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Corporation for such purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Corporation and the Security Registrar and duly executed by, the Holder hereof
or his attorney duly authorized in writing, and thereupon one or more new
Securities of this series, of authorized denominations and of like tenor and for
the same aggregate principal amount, will be issued to the designated transferee
or transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

         The Trustee, Paying Agent, Conversion Agent and Security Registrar
under the Indenture, each in its individual or any other capacity, may become
the owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Corporation or its Affiliates and may otherwise
deal with the Corporation or its Affiliates with the same rights it would have
if it were not Trustee, Paying Agent, Conversion Agent or Security Registrar.

         The Corporation will be responsible for making all calculations called
for under the Securities of this series. These calculations include, but are not
limited to, determination of the Trading Price, Current Market Price, Last
Reported Sale Price, Spin-off Market Price, accrued interest payable (including
any Contingent Interest) on the Securities of this series and Conversion Rate of
the Securities of this series. The Corporation will make these calculations in
good faith and, absent manifest error, these calculations will be final and
binding on the Holders of the Securities of this series. Promptly after the
calculation thereby, the Corporation will provide to each of the Trustee and the
Conversion Agent an Officers' Certificate setting forth a schedule of its
calculations and each of the Trustee and the Conversion Agent is entitled to
rely

                                      A-9
<PAGE>
upon the accuracy of such calculations without independent verification. The
Trustee will forward the Corporation's calculations to any Holder upon the
request of such Holder.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of the Securities of this series and for covenant defeasance
at any time of certain covenants in the Indenture upon compliance with certain
conditions set forth in the Indenture.

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

         The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to the limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series of a different authorized denomination, as
requested by the Holder surrendering the same upon surrender of the Security or
Securities to be exchanged at the office or agency of the Corporation.

         The Corporation agrees, and by acceptance of beneficial ownership
interest in the Securities of this series each beneficial holder of such
Securities will be deemed to have agreed, for United States federal income tax
purposes (1) to treat the Securities of this series as indebtedness that is
subject to Treas. Reg. Sec. 1.1275-4 (the "Contingent Payment Regulations") and,
for purposes of the Contingent Payment Regulations, to treat the fair market
value of any stock beneficially received by a beneficial holder upon any
conversion of such Securities as a contingent payment and (2) to be bound by the
Corporation's determination of the "comparable yield" and "projected payment
schedule," within the meaning of the Contingent Payment Regulations, with
respect to the Securities of this series. A Holder of Securities of this series
may obtain the issue price, the amount of original issue discount, issue date,
yield to maturity, comparable yield and projected payment schedule for such
Securities by submitting a written request for such information to the
Corporation at the following address: Duke Energy Corporation, 526 South Church
Street, Charlotte North Carolina 28202, Attention: David L. Hauser, Senior Vice
President and Treasurer.

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK.
