are registered on the Regular Record Date for such Interest Payment Date. Any
such interest that is not so punctually paid or duly provided for will forthwith
cease to be payable to the Holders on such Regular Record Date and may either be
paid to the Person or Persons in whose name the Series G Senior 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 (in accordance with Section
307 of the Original Indenture)(a "Special Record Date"), notice whereof shall be
given to Holders of the Series G Senior Notes not less than ten (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 Series G Senior 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.

         (b) In addition, contingent interest ("Contingent Interest"), if any,
will accrue on each Series G Senior Note during any six-month period from
December 15 to June 14 and from June 15 to December 14, as appropriate,
commencing with the six-month period beginning December 15, 2006, if the average
Trading Price for each $1,000 principal amount of the Series G Senior Notes for
the Applicable Five Day Trading Period with respect to such Interest Period
equals 120% or more of such principal amount of Series G Senior Notes. The
amount of Contingent Interest payable per $1,000 principal amount of Series G
Senior 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 Series G Senior
Notes for the Applicable Five Day Trading Period with respect to such Interest
Period. Contingent Interest, if any, will accrue from December 15 or June 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 Series
G Senior Notes will be entitled to receive Contingent Interest during an
Interest Period, as promptly as practicable after such determination, the
Company shall provide notice thereof to the Holders of the Series G Senior
Notes.

         (c) Payments of interest on the Series G Senior Notes will include
interest accrued to but excluding the respective Interest Payment Date,
Redemption Date, Put Date or Fundamental Change Purchase Date, as the case may
be. Interest payments for the Series G Senior Notes shall be computed and paid
on the basis of a 360-day year of twelve 30-day months. If any date on which
interest is payable on the Series G Senior Notes is not a Business Day, then
payment of the interest 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), in each case with the same force and effect as if made on the
date the payment was originally payable.

         (d) Payment of the principal and interest on the Series G Senior Notes
shall be made at the office of the Paying Agent 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 interest (including interest on any
Interest Payment Date) will be made, at the option of the Company, (i)

                                       8

<PAGE>

by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or (ii) 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. If any date on which principal
and interest is payable on the Series G Senior Notes is not a Business Day, then
payment of the principal and interest 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), in each case with the same force and effect as if
made on the date the payment was originally payable.

         SECTION 104. Denominations. The Series G Senior Notes may be issued in
denominations of $1,000, or any integral multiple thereof.

         SECTION 105. Global Securities. The Series G Senior Notes will be
issued initially in the form of one or more Global Securities registered in the
name of the Depositary (which shall be The Depository Trust Company) or its
nominee. Except under the limited circumstances described below, Series G Senior
Notes represented by such Global Securities will not be exchangeable for, and
will not otherwise be issuable as, Series G Senior Notes in definitive form. The
Global Securities described above 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.

         Owners of beneficial interests in such a Global Security will not be
considered the Holders thereof for any purpose under the Indenture, and no
Global Security representing a Series G Senior Note shall be exchangeable,
except for another Global Security of like denomination and tenor to be
registered in the name of the Depositary or its nominee or to a successor
Depositary or its nominee or except as described below. The rights of Holders of
such Global Security shall be exercised only through the Depositary.

         A Global Security shall be exchangeable for Series G Senior Notes
registered in the names of persons other than the Depositary or its nominee only
if (i) the Depositary notifies the Company 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 Company within 90 days of receipt by the
Company 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 Company within 90 days after it
becomes aware of such cessation or (ii) the Company 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 Series G Senior Notes registered in such names as the
Depositary shall direct.

         SECTION 106. Optional Redemption. (a) On or after December 20, 2006,
the Series G Senior Notes shall be redeemable, in whole or from time to time in
part, at the option of the Company on any date (a "Redemption Date"), at a
redemption price equal to 100% of the principal amount of the Series G Senior
Notes to be redeemed plus any accrued and unpaid interest on the principal
amount to be redeemed to but excluding the Redemption Date (the "Redemption
Price").

                                       9

<PAGE>

         (b) The Company shall notify each Holder of the redemption in the
manner provided in Section 1104 of the Original Indenture.

         (c) If any Series G Senior 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 Series G Senior Notes so
selected, the converted portion of such Series G Senior Notes shall be deemed
(so far as may be), solely for purposes of determining the aggregate principal
amount of Series G Senior Notes to be redeemed by the Company, to be the portion
selected for redemption. Series G Senior Notes which have been converted during
a selection of Series G Senior Notes to be redeemed may be treated by the
Trustee as Outstanding for the purpose of such selection. Nothing in this
Section 106(c) shall affect the right of any Holder to convert any Series G
Senior Notes before the termination of the conversion right with respect
thereto.

         (d) In addition to those matters set forth in Section 1104 of the
Indenture, a notice of redemption sent to the Holders of Series G Senior Notes
shall state:

                  (i)   the name of the Paying Agent and Conversion Agent;

                  (ii)  the then current Conversion Rate;

                  (iii) that the Series G Senior Notes called for redemption may
         be converted at any time prior to the close of business on the Business
         Day immediately preceding the Redemption Date; and

                  (iv)  that Holders who wish to convert Series G Senior Notes
         must comply with the procedures in Section 110 of this Twenty-Third
         Supplemental Indenture and the fourth through ninth paragraphs of the
         reverse of the Series G Senior Notes.

         (e) In the event of the redemption of the Series G Senior Notes in part
only, a new Series G Senior Note or Notes for the unredeemed portion will be
issued in the name or names of the Holders thereof upon surrender thereof.

         SECTION 107. Purchase Upon a Fundamental Change. (a) If a Fundamental
Change shall occur at any time prior to Stated Maturity, each Holder shall have
the right, at such Holder's option, to require the Company to purchase any or
all of such Holder's Series G Senior Notes for cash on the date designated by
the Company that is no later than 30 days after the date of the Company Purchase
Notice of the occurrence of such Fundamental Change (subject to extension if
necessary to comply with applicable law, as provided in Section 109(g)) (the
"Fundamental Change Purchase Date"). The Company shall purchase such Series G
Senior Notes at a price (the "Fundamental Change Purchase Price") equal to 100%
of the principal amount of the Series G Senior Notes to be purchased plus any
accrued and unpaid interest on the principal amount to be purchased to but
excluding the Fundamental Change Purchase Date. No Series G Senior Notes may be
purchased at the option of the Holders due to a Fundamental Change if the
principal amount of the Series G Senior Notes has been accelerated and such
acceleration has not been rescinded.

                  G Senior Notes which the Holder shall deliver to be purchased,
                  which portion must be $1,000 or an integral multiple thereof;
                  and

                           (3) that such Series G Senior Notes shall be
                  purchased as of the Fundamental Change Purchase Date pursuant
                  to the terms and conditions specified in the Series G Senior

         Notes prior to, on or after the Fundamental Change Purchase Date
         (together with all necessary endorsements) at the offices of the Paying
         Agent, such delivery or transfer being a condition to receipt by the
         Holder of the Fundamental Change Purchase Price therefor; provided,
         however, that such Fundamental Change Purchase Price shall be so paid
         pursuant to this Section 107 only if the Series G Senior 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 108. Purchase at the Option of the Holder. (a) On each of
December 15, 2006, December 15, 2008, December 15, 2013 and December 15, 2018
(each, a "Put Date"), each Holder shall have the right, at such Holder's option,
to require the Company to purchase any or all of such Holder's Series G Senior
Notes for cash. The Company shall purchase such Series G Senior Notes at a price
equal to 100% of the principal amount of the Series G Senior Notes to be
purchased plus any accrued and unpaid interest on the principal amount to be
purchased to but excluding the Put Date.

         (b) For a Series G Senior Note to be so purchased at the option of the

         such Put Date. The Put Notice shall state:

<PAGE>

                           (1) if certificated, the certificate numbers of the
                  Series G Senior Notes which the Holder shall deliver to be
                  purchased;

                           (2) the portion of the principal amount of the Series
                  G Senior Notes which the Holder shall deliver to be purchased,
                  which portion must be $1,000 or an integral multiple thereof;
                  and

                           (3) that such Series G Senior Notes shall be
                  purchased as of the Put Date pursuant to the terms and

                  (ii) delivery or book-entry transfer of such Series G Senior
         Notes to the Paying Agent prior to, on or after the Put Date (together
         with all necessary endorsements) at the offices of the Paying Agent,
         such delivery or transfer being a condition to receipt by the Holder of
         the Purchase Price therefor; provided, however, that such Purchase
         Price shall be so paid pursuant to this Section 108 only if the Series
         G Senior Notes so delivered or transferred to the Paying Agent shall
         conform in all respects to the description thereof in the related Put
         Notice.

         SECTION 109. Further Conditions and Procedures for Purchase. (a) The
Company shall send notices (each, a "Company Purchase Notice") to the Holders
(and to beneficial owners if required by applicable law) at their addresses
shown in the Series G Senior Note register maintained by the Security Registrar,
and shall deliver a copy of each such notice to the Trustee and Paying Agent,
not less than 30 Business Days prior to each Put Date, or on or before the 30th
day after the occurrence of the Fundamental Change, as the case may be (each
such date of delivery, a "Company Purchase Notice Date"). Any such notice
delivered to the Trustee and the Paying Agent with respect to a Fundamental
Change shall be accompanied by an Officers' Certificate certifying that a
Fundamental Change has occurred and as to the date of the occurrence thereof, on
which Certificate the Trustee and the Paying Agent may conclusively rely. Each

                  interest that will be payable with respect to the Series G
                  Senior Notes on the applicable Put Date or Fundamental Change

                           (ii)  if the notice relates to a Fundamental Change,
                  the events causing the Fundamental Change and the date of the
                  Fundamental Change;

                  its purchase right;

                           (v)   the name and address of the Paying Agent and

                  or Fundamental Change Purchase Price;

                           (vii)  that Series G Senior Notes as to which a Put
                  Notice or Fundamental Change Purchase Notice has been given by
                  the Holder to the Company may be converted only if the
                  applicable Put Notice or Fundamental Change Purchase Notice
                  has been withdrawn by the Holder in accordance with the terms
                  of this Twenty-Third Supplemental Indenture; provided that the
                  Series G Senior Notes are otherwise convertible in accordance
                  with the fourth through ninth paragraphs of the reverse of the
                  Series G Senior Notes;

                           (viii) that the Purchase Price or Fundamental Change
                  Purchase Price for any Series G Senior Notes as to which a Put
                  Notice or a Fundamental Change Purchase Notice, as applicable,
                  has been given and not withdrawn shall be paid by the Paying
                  Agent promptly following the later of the Put Date or
                  Fundamental Change Purchase Date, as applicable, or the time
                  of book-entry transfer or delivery of such Series G Senior
                  Notes;

                           (ix)   the procedures the Holder must follow under
                  Sections 107 or 108, as applicable, and Section 109;

                           (x)    briefly, the conversion rights of the Series G
                  Senior Notes and whether, at the time of such notice, the
                  Series G Senior Notes are eligible for conversion;

                           (xi)   that, unless the Company defaults in making
                  payment of such Purchase Price or Fundamental Change Purchase
                  Price on Series G Senior Notes covered by any Put Notice or
                  Fundamental Change Purchase Notice, as applicable, interest
                  will cease to accrue on and after the Put Date or Fundamental
                  Change Purchase Date, as applicable;

                           (xii)  the CUSIP and, if applicable, the ISIN number
                  of the Series G Senior Notes; and

                           (xiii) the procedures for withdrawing a Put Notice or
                  Fundamental Change Purchase Notice.

         At the Company's request, made at least five Business Days prior to the
date upon which such notice is to be mailed, and at the Company's expense, the
Paying Agent shall give the Company Purchase Notice in the Company's name;
provided, however, that, in all cases, the text of the Company Purchase Notice
shall be prepared by the Company.

         (b) Upon receipt by the Paying Agent on behalf of the Company from the
Holder of the Fundamental Change Purchase Notice or the Put Notice specified in
Section 107(b)(i) or Section 108(b)(i), as applicable, the Holder of the Series
G Senior Notes in respect of which such Fundamental Change Purchase Notice or
the Put Notice, as the case may be, was given shall (unless such Fundamental
Change Purchase Notice or the Put Notice is withdrawn as specified in the
following two paragraphs) thereafter be entitled to receive solely the
Fundamental Change

                                       13

<PAGE>

Purchase Price or the Purchase Price with respect to such Series G Senior Notes.
Such Fundamental Change Purchase Price or Purchase Price shall be paid by the
Paying Agent to such Holder promptly following the later of (x) the Fundamental
Change Purchase Date or the Put Date, as the case may be, with respect to such
Series G Senior Notes (provided the conditions in Section 107(b) or Section
108(b), as applicable, have been satisfied) and (y) the time of delivery or
book-entry transfer of such Series G Senior Notes to the Paying Agent by the
Holder thereof in the manner required by Section 107(b)(ii) or Section
108(b)(ii), as applicable.

         Series G Senior 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 109(c) or (e); provided that the Series G
Senior Notes are otherwise convertible in accordance with the fourth through
ninth paragraphs of the reverse of the Series G Senior 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 Company shall deposit
with the Paying Agent (or if the Company or an Affiliate of the Company 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 Series G Senior Notes to be purchased pursuant
to Section 107 or Section 108, as applicable. Payment by the Paying Agent of
such Fundamental Change Purchase Price or Purchase Price for such Series G
Senior 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 Series G Senior 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 Series G Senior Notes on the Fundamental Change Purchase Date or the Put
Date, as the case may be, then, on and after such date, such Series G Senior
Notes shall cease to be Outstanding and interest (including any Contingent
Interest) on such Series G Senior Notes shall cease to accrue, whether or not
book-entry transfer of such Series G Senior Notes is made or such Series G
Senior 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 Series G Senior Notes). Nothing herein shall preclude the
Company's withholding any tax required by law.

         The Company 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 Company in making any such
payment. If the Company or an Affiliate of the Company acts as Paying Agent, it
shall segregate the money held by it as Paying Agent and hold it as a separate
trust fund. The Company at any time may require a Paying Agent to deliver all
money held by it pursuant to this Section 109 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.

                                       14

<PAGE>

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

         (c) A Put Notice or Fundamental Change Purchase Notice, as the case may
be, may be withdrawn by 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 fifth 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 Series G
         Senior Notes in respect of which such notice of withdrawal is being
         submitted;

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

                  (iii) the principal amount, if any, of such Series G Senior
         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 Company.

         The Paying Agent shall promptly notify the Company 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 107 or 108 and this
Section 109, if the Series G Senior 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) There shall be no purchase of any Series G Senior Notes pursuant to
Section 107 or Section 108 if the principal amount of the Series G Senior Notes
has been accelerated and such acceleration has not been rescinded. The Paying
Agent shall promptly return to the respective Holders thereof any Series G
Senior 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
Twenty-Third Supplemental Indenture, or (y) if the principal amount of the
Series G Senior Notes has been accelerated and such acceleration has not been
rescinded, 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) Any Series G Senior Notes that are to be purchased only in part
shall be surrendered at the office of the Paying Agent (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holder's attorney duly authorized in writing) and the Company
shall execute and the Trustee or the Authenticating Agent, if any, shall
authenticate and deliver to the Holder of such Series G Senior Notes, without
service charge, a new Series G Senior Note or Series G Senior 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
Series G Senior Notes so surrendered which is not purchased.

         (g) In connection with any offer to purchase Series G Senior Notes
under Sections 107 or 108 hereof, the Company 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 107, 108 or this Section
109 to be exercised in the manner specified in Sections 107, 108 or this Section
109; provided, however, that the Company shall not take any action in violation
of any applicable federal or state securities laws.

         (h) The Trustee and the Paying Agent shall return to the Company 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 Company
pursuant to Section 109(b) exceeds the aggregate Purchase Price or Fundamental
Change Purchase Price, as the case may be, of the Series G Senior Notes or
portions thereof which the Company 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 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 Company.

         (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 Series G Senior Notes) payment of
interest 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 110. Conversion of the Series G Senior Notes. (a) A Holder may
convert its Series G Senior Notes for Common Stock at any time during the
periods specified in the fourth paragraph of the reverse of the Series G Senior
Notes.

         (b) The initial Conversion Rate is 13.5865 shares of Common Stock
issuable upon conversion of $1,000 principal amount of a Series G Senior Note
(the "Conversion Rate"), subject to adjustment as herein set forth. A Holder may
convert a portion of the principal amount of Series G Senior Notes if the
portion is $1,000 or an integral multiple thereof.

         (c) To convert Series G Senior Notes, the requirements set forth in
this Section 110(c) and in the fourth through ninth paragraphs of the reverse of
the Series G Senior Notes must be satisfied.

                  (i) To convert the Series G Senior Notes, a Holder must (1)
         complete and manually sign the irrevocable conversion notice on the
         back of the Series G Senior Notes (or complete and manually sign a
         facsimile of such notice) and deliver such notice to the

                                       16

<PAGE>

         Conversion Agent at the office maintained by the Conversion Agent for
         such purpose, (2) with respect to Series G Senior Notes in
         certificated form, surrender the Notes to the Conversion Agent or with
         respect to Series G Senior 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 Company 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 Company
         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 110(d).

                  (ii)   of Series G Senior Notes 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 Series G Senior Notes at any time after the close of business
         on such Regular Record Date. Series G Senior 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 that the Holder is to receive on the Series G Senior Notes;
         provided, however, that no such payment need be made with respect to
         Series G Senior 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 Series G Senior 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 Series G Senior Notes on any date when the stock transfer
         books of the Company 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 Series G Senior Notes shall have
         been surrendered for conversion, as if the stock transfer books of the
         Company had not been closed. Upon conversion of Series G Senior Notes,
         such Person shall no longer be a Holder of such Series G Senior 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 110(g) or as otherwise provided in the Indenture.
         If a Holder converts more than one Series G Senior 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 Series G Senior
         Notes converted. Upon surrender of a Series G Senior Note that is
         converted in part, the

                                       17

<PAGE>

         Company shall execute, and the Trustee or the Authenticating Agent
         shall authenticate and deliver to the Holder, a new Series G Senior
         Note in an authorized denomination equal in principal amount to the
         unconverted portion of the Series G Senior Note surrendered. If the
         last day on which Series G Senior Notes may be converted is not a
         Business Day in a place where a Conversion Agent is located, the
         Series G Senior Notes may be surrendered to that Conversion Agent on
         the next succeeding day that is a Business Day. A Holder of Series G
         Senior Notes is not entitled to any rights of a holder of Common Stock
         until such Holder has converted its Series G Senior Notes to Common
         Stock, and only to the extent such Series G Senior Notes are deemed to
         have been converted into Common Stock pursuant to this Section 110.

         (d) The Company shall not issue a fractional share of Common Stock upon
conversion of Series G Senior Notes. Instead the Company 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) If a Holder converts Series G Senior Notes, the Company 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 Company's withholding
any tax required by law.

         (f) The Company shall, prior to issuance of any Series G Senior 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 Series G Senior Notes. All shares of
Common Stock delivered upon conversion of the Series G Senior 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 Company shall endeavor promptly to comply with
all federal and state securities laws regulating the order and delivery of
shares of Common Stock upon the conversion of Series G Senior 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. Each share of Common Stock issued upon
conversion of the Series G Senior Notes shall be entitled to receive the
appropriate number of common stock or preferred stock purchase rights, as the
case may be ("Rights"), if any, that shares of Common Stock are entitled to
receive and the certificates representing the Common Stock issued upon such
conversion shall bear such legends, if any, in each case as may be provided by
the terms of any shareholder rights agreement adopted by the Company, as the
same may be amended from time to time (in each case, a "Rights Agreement").

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

                                       18

<PAGE>

                  (i)  In case the Company 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 110(g)(i), the number of shares of Common Stock at any
         time outstanding shall not include shares held in treasury by the
         Company but shall include any shares issuable in respect of any scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company will not pay any dividend or make any distribution on shares of
         Common Stock held in treasury by the Company. If any dividend or
         distribution of the type described in this Section 110(g)(i) is
         declared but not so paid or made, the Conversion Rate shall again be
         adjusted to the Conversion Rate that would then be in effect if such
         dividend or distribution had not been declared.

                  (ii) In case the Company shall issue rights, options or
         warrants to all holders of its Common Stock 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. For the purposes of this
         Section 110(g)(ii), the number of shares of Common Stock at any time
         outstanding shall not include shares held in treasury by the Company
         but shall include any shares issuable in respect of any scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company shall not issue any such rights, options or warrants in respect
         of shares of Common Stock held in treasury by the Company. Such
         adjustment pursuant to this Section 110(g)(ii) shall be successively
         made whenever any such rights, options or warrants are issued, and
         shall become effective immediately after the opening of business on the
         day following the date fixed for determination of stockholders entitled
         to receive such rights or warrants. To the extent that shares of Common
         Stock are not delivered after the expiration of such rights, options or
         warrants, the Conversion Rate shall be readjusted to the Conversion
         Rate that would then be in effect had the adjustments made upon the
         issuance of such rights,

                                       19

<PAGE>

         options or warrants been made on the basis of delivery of only the
         number of shares of Common Stock actually delivered. If such rights,
         options or warrants are not so issued, the Conversion Rate shall again
         be adjusted to be the Conversion Rate that would then be in effect if
         such date fixed for the determination of stockholders entitled to
         receive such rights, options or warrants had not been fixed. In
         determining whether any rights, options or warrants entitle the
         holders to subscribe for or purchase shares of Common Stock at a price
         less than the average of the Current Market Price per share of the
         Common Stock, and in determining the aggregate offering price of such
         shares of Common Stock, there shall be taken into account any
         consideration received by the Company for such rights, options or
         warrants and any amount payable on exercise or conversion thereof, the
         value of such consideration, if other than cash, to be determined by
         the Board of Directors.

                  (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 Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock evidences of its
         indebtedness, shares of capital stock, securities, cash, property or
         assets (but excluding any rights, options or warrants referred to in
         Section 110(g)(ii) of this Section, any dividend or distribution paid
         exclusively in cash and any dividend or distribution referred to in
         Section 110(g)(i)) (any of the foregoing hereinafter in this Section
         110(g)(iv) called the "Distributed Securities"), 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 Distributed Securities 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 that if the then Fair Market
         Value (as so determined) of the portion of the Distributed Securities
         so distributed applicable to one share of Common Stock is equal to or
         greater than the Current Market Price per share of the Common Stock on
         the date fixed for the determination of stockholders entitled to
         receive such distribution, in lieu of the foregoing adjustment,
         adequate provision shall be made so that each holder shall have the
         right to receive upon conversion the amount of Distributed Securities
         such holder would have received had such holder converted the Series G
         Senior Note on the date fixed for such determination. If such dividend
         or distribution is not so paid or made, the

                                       20

<PAGE>

         Conversion Rate shall again be adjusted to be the Conversion Rate that
         would then be in effect if such dividend or distribution had not been
         declared. If the Board of Directors determines the Fair Market Value
         of any distribution for purposes of this Section 110(g)(iv) by
         reference to the actual or when issued trading market for any
         securities, it must in doing so consider the prices in such market
         over the same period used in computing the Current Market Price on the
         applicable date fixed for the determination of stockholders entitled
         to receive such distribution. In any case in which this Section
         110(g)(iv) is applicable, Sections 110(g)(i) and (ii) shall not be
         applicable.

                  Rights, options or warrants distributed by the Company to all
         holders of Common Stock entitling the holders thereof to subscribe for
         or purchase shares of the Company's capital stock (either initially or
         under certain circumstances), which rights, options or warrants, until
         the occurrence of a specified event or events ("Trigger Event"): (i)
         are deemed to be transferred with such shares of Common Stock; (ii) are
         not exercisable; and (iii) are also issued in respect of future
         issuances of Common Stock, shall be deemed not to have been distributed
         for purposes of this Section 110(g) (and no adjustment to the
         Conversion Rate under this Section 110(g) will be required) until the
         occurrence of the earliest Trigger Event, whereupon such rights,
         options and warrants shall be deemed to have been distributed and an
         appropriate adjustment (if any is required) to the Conversion Rate
         shall be made under this Section 110(g)(iv). If any such right, option
         or warrant, including any such existing rights, options or warrants
         distributed prior to the Original Issue Date, are subject to events,
         upon the occurrence of which such rights, options or warrants become
         exercisable to purchase different securities, evidences of indebtedness
         or other assets, then the date of the occurrence of any and each such
         event shall be deemed to be the date of distribution and record date
         with respect to new rights, options or warrants with such rights (and a
         termination or expiration of the existing rights, options or warrants
         without exercise by any of the holders thereof). In addition, in the
         event of any distribution (or deemed distribution) of rights, options
         or warrants, or any Trigger Event or other event (of the type described
         in the preceding sentence) with respect thereto that was counted for
         purposes of calculating a distribution amount for which an adjustment
         to the Conversion Rate under this Section 110(g) was made, (I) in the
         case of any such rights, options or warrants that shall all have been
         redeemed or repurchased without exercise by any holders thereof, the
         Conversion Rate shall be readjusted upon such final redemption or
         repurchase to give effect to such distribution or Trigger Event, as the
         case may be, as though it were a cash distribution, equal to the per
         share redemption or repurchase price received by a holder or holders of
         Common Stock with respect to such rights, options or warrants (assuming
         such holder had retained such rights, options or warrants), made to all
         holders of Common Stock as of the date of such redemption or
         repurchase, and (II) in the case of such rights, options or warrants
         that shall have expired or been terminated without exercise thereof,
         the Conversion Rate shall be readjusted as if such expired or
         terminated rights and warrants had not been issued.

                  For purposes of this Section 110(g)(iv) and Section 110(g)(i)
         and Section 110(g)(ii), any dividend or distribution to which this
         Section 110(g)(iv) is applicable that also includes shares of Common
         Stock, or rights, options or warrants to subscribe for or purchase
         shares of Common Stock (or both), shall be deemed instead to be (x) a
         dividend or distribution of the evidences of indebtedness, assets or
         shares of capital stock other

                                       21

<PAGE>

         than such shares of Common Stock or rights, options or warrants (and
         any Conversion Rate adjustment required by this Section 110(g)(iv) with
         respect to such dividend or distribution shall then be made)
         immediately followed by (y) a dividend or distribution of such shares
         of Common Stock or such rights, options or warrants (and any further
         Conversion Rate adjustment required by Sections 110(g)(i) and 110(g)
         (ii) with respect to such dividend or distribution shall then be made),
         except any shares of Common Stock included in such dividend or
         distribution shall not be deemed "outstanding at the close of business
         on the date fixed for such determination" within the meaning of Section
         110(g)(i).

                  (v) In case the Company shall make any dividend or
         distribution consisting exclusively of cash to all holders of
         outstanding shares of Common Stock (excluding (I) any dividend or
         distribution in connection with the liquidation, dissolution or winding
         up of the Company, or (II) any quarterly cash dividend on Common Stock
         to the extent that the aggregate cash dividend per share of Common
         Stock in any quarter does not exceed the dividend threshold amount
         ($0.645 initially being the "Dividend Threshold Amount" and such amount
         being subject to adjustment from time to time in a manner inversely
         proportional to adjustments to the Conversion Rate, provided that there
         shall be no adjustment to the Dividend Threshold Amount for adjustments
         to the Conversion Rate under this Section 110(g)(v))), then the
         Conversion Rate will be adjusted by multiplying the applicable
         Conversion Rate by a fraction, the numerator of which will be the
         Current Market Price minus the Dividend Threshold Amount and the
         denominator of which will be the Current Market Price minus the amount
         per share of such dividend or distribution, such adjustment to be
         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 that if an adjustment is
         required to be made under this clause as a result of a distribution
         that is not a quarterly dividend, the dividend threshold amount will be
         deemed to be zero; and provided further that if the portion of the cash
         so distributed applicable to one share of Common Stock is equal to or
         greater than the Current Market Price on the date fixed for the
         determination of stockholders entitled to receive such distribution, in
         lieu of the foregoing adjustment, adequate provision shall be made so
         that each Holder shall have the right to receive upon conversion the
         amount of cash such Holder would have received had such Holder
         converted each Series G Senior Note on the date fixed for such
         determination.

                  (vi) If a tender or exchange offer made by the Company or any
         Subsidiary for all or any portion of the Common Stock expires and such
         tender or exchange offer (as amended up to the expiration thereof)
         requires the payment to tendering stockholders of consideration per
         share of Common Stock having a Fair Market Value (as determined by the
         Board of Directors, whose determination shall be conclusive and
         described in a Board Resolution) that as of the last time (the
         "Expiration Time") tenders or exchanges may be made under such tender
         or exchange offer (as it may be amended) exceeds the average of the
         Last Reported Sale Price of a share of Common Stock for each of the 10
         consecutive Trading Days next succeeding the Expiration Time, the
         Conversion Rate shall be increased by multiplying the Conversion Rate
         in effect immediately before the Expiration Time by a fraction, (I) the
         numerator of which shall be the sum of (x) the Fair Market Value (as
         determined by the Board of Directors, whose determination shall be
         conclusive

                                       22

<PAGE>

         and described in a Board Resolution) of the aggregate consideration
         payable to stockholders based on the acceptance (up to any maximum
         specified in the terms of the tender or exchange offer) of all shares
         validly tendered or exchanged 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") and (y) the product of the
         number of shares of Common Stock outstanding (less any Purchased
         Shares) at the Expiration Time and the average of the Last Reported
         Sale Price of a share of Common Stock for each of the 10 consecutive
         Trading Days next succeeding the Expiration Time, and (II) the
         denominator of which shall be the number of shares of Common Stock
         outstanding (including any tendered or exchanged shares) at the
         Expiration Time multiplied by the average of the Last Reported Sale
         Price of a share of Common Stock for each of the 10 consecutive Trading
         Days next succeeding the Expiration Time, such adjustment to become
         effective immediately prior to the opening of business on the day
         following the Expiration Time. If the Company is obligated to purchase
         shares under any such tender or exchange offer, but the Company is
         permanently prevented by applicable law from effecting any such
         purchases or all such purchases are rescinded, the Conversion Rate
         shall again be adjusted to be the Conversion Rate that would then be in
         effect if such tender or exchange offer had not been made.

                  (vii) The reclassification of Common Stock into securities
         including securities other than Common Stock (other than any
         reclassification upon an event to which Section 110(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 110(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 110(g)(iii)).

                  (viii) In the event that the Company 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
         Company, 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 and the
         denominator shall be the Spin-off Market Price per share of the Common
         Stock plus the Spin-off Market Price per share or similar equity
         interest of the subsidiary or other business unit of the Company, 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 Company; provided that
         if (x) the average of the Spin-Off Market Price of the Common Stock
         minus (y) the Spin-Off Market Price of the securities distributed in
         respect of each share of Common Stock for

                                       23

<PAGE>

         which this Section 110(g)(viii) applies is less than $1.00, then the
         adjustment provided by for by this Section 110(g)(viii) shall not be
         made and in lieu thereof the provisions of Section 110(g)(iv) shall
         apply to such distribution. In any case in which this Section 110(g)
         (viii) is applicable, Sections 110(g)(i), (ii) and (iv) shall not be
         applicable.

                  (ix) 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.

                  (x) Notwithstanding the provisions of Section 110(g)(ii) or
         (iv), no adjustment shall be made thereunder, nor shall an adjustment
         be made to the ability of a Holder of a Series G Senior Note to
         convert, for any distribution described therein if the Holder will
         otherwise participate in the distribution without conversion of such
         Holder's Series G Senior Notes.

                  (xi) So long as each share of Common Stock issued upon
         conversion of the Series G Senior Notes is entitled to receive the
         appropriate number of Rights, if any, that shares of Common Stock are
         entitled to receive in accordance with the terms of any Rights
         Agreement, there shall not be any adjustment to the Conversion Rate as
         a result of the issuance of Rights under a Rights Agreement; provided
         that an adjustment to the Conversion Rate shall be made in accordance
         with Section 110(g)(iv) if the Rights separate from the Common Stock.

                  (xii) For purposes of this Section 110(g), "Fair Market Value"
         means the amount that a willing buyer would pay a willing seller in an
         arm's-length transaction. In the case of marketable equity securities,
         the Fair Market Value shall be determined based on the prevailing
         market price of such securities.

         (h) Conversion rate adjustments:

                       (i) 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 Company 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 Company 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

                                       24

<PAGE>

                 described in (2) above and outstanding as of the date the
                 Series G Senior Notes were first issued;

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

                           (5) for accrued and unpaid interest.

                           To the extent the Series G Senior Notes become
                 convertible into cash, assets or property (other than capital
                 stock of the Company or securities to which Section 110(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) Whenever the Conversion Rate is adjusted, the Company
         shall promptly mail to Holders a notice of the adjustment. The Company
         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) The Company may make such increases in the Conversion
         Rate, in addition to those required by Section 110(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 Company may from time to time
         increase the Conversion Rate by any amount if the Board of Directors
         shall have made a determination that such increase would be in the best
         interests of the Company, which determination shall be conclusive.
         Whenever the Conversion Rate is so increased, the Company 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
         notice shall state the increased Conversion Rate and the period it
         shall be in effect.

                 (iv) 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 Company with another Person 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 Company to any other Person 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 Company or the successor or purchasing Person, as the case
         may be, shall execute with the Trustee a supplemental indenture or
         otherwise amend the terms of the Series G Senior Notes, to provide that
         each Series G Senior Note shall be convertible

                                       25

<PAGE>

         into the kind and amount of shares of stock, other securities or
         property or assets (including cash) that the Holder of the Series G
         Senior Note would have received upon such reclassification, change,
         consolidation, merger, binding share exchange, sale or conveyance if
         such Holder had converted such Series G Senior Note into the number of
         shares of Common Stock issuable upon conversion of such Series G Senior
         Note immediately prior to such reclassification, change, consolidation,
         merger, combination, binding share exchange, sale or conveyance. Such
         supplemental indenture or other amendment to the Series G Senior Notes
         shall provide for adjustments which shall be as nearly equivalent as
         may be practicable to the adjustments provided for in Section 110(g).
         The Company shall cause notice of the execution of such supplemental
         indenture or amendment of the Series G Senior Notes to be mailed to
         each Holder, at its address appearing on the Series G Senior 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 110(h)(iv) applies to any event or
         occurrence, Section 110(g) shall not apply.

                  (v) 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 Series G Senior 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 Company 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 Series G Senior Notes for the purpose of
         conversion or to comply with any of the duties, responsibilities or
         covenants of the Company contained in this Section 110. 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 110(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
         Series G Senior Notes after any event referred to in such Section
         110(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 Company 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 Series G Senior Notes has occurred which makes the
         Series G Senior Notes eligible for

                                       26

<PAGE>

         conversion or no longer eligible therefor until the Company 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
         Company agrees to deliver such Officers' Certificate to the Trustee and
         the Conversion Agent immediately after the occurrence of any such
         event.

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

                  (vii) Whenever successive adjustments to the Conversion Rate
         are called for pursuant to Sections 110(g) or 110(h), such adjustments
         shall be made to the Current Market Price as may be necessary or
         appropriate to effectuate the intent of 110(g) or 110(h) and to avoid
         unjust or inequitable results as determined in good faith by the Board
         of Directors.

         (i) On conversion of a Series G Senior Note, that portion of accrued
and unpaid interest on the converted Series G Senior 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 Series G Senior 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 Series G Senior 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 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 Series G Senior Note being converted pursuant to
the provisions hereof.

         SECTION 111. 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 Series G Senior Notes shall also mean any of the following
events:

         (i) default in the payment of any interest upon the Series G Senior
Notes when it becomes due and payable, and continuance of such default for a
period of 30 days; or

         (ii) default in the payment of the principal of the Series G Senior
Notes, at their Maturity, upon a redemption by the Company pursuant to Section
106, or pursuant to the Company's obligation to repurchase Series G Senior Notes
upon the occurrence of a Fundamental Change pursuant to Section 107 or upon the
exercise by a holder of its option to require the Company to repurchase such
holder's Series G Senior Notes pursuant to Section 108;

         (iii) default in the Company's obligation to convert the Series G
Senior Notes upon exercise of a Holder's conversion right; or

                                       27

<PAGE>

     (iv) failure to provide notice of a Fundamental Change on or before the
30/th/ day after the occurrence of such Fundamental Change.

     SECTION 112. Amendments; Waiver. In addition to those matters set forth in
Section 902 of the Original Indenture, with respect to the Series G Senior
Notes, no amendment or supplemental indenture shall without the consent of the
Holder of each Series G Senior Note affected thereby:

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

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

     In addition, with respect to the Series G Senior 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 Series G Senior Notes
may waive an existing default other than: (I) any default by the Company in any
payment of the Redemption Price, Purchase Price or Fundamental Change Purchase
Price with respect to any Series G Senior Notes, or (II) any default which
constitutes a failure to convert any Series G Senior Note in accordance with its
terms and the Indenture.

     SECTION 113. Register of Securities; Paying Agent; Conversion Agent.
Initially, the Trustee shall act as Paying Agent, Conversion Agent and Security
Registrar with respect to the Series G Senior Notes with the Place of Payment
for the Series G Senior Notes initially being the Corporate Trust Office. The
Company 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 Company
or any of its Subsidiaries or any of their Affiliates may act as Paying Agent,
Conversion Agent, Security Registrar or co-registrar.

     SECTION 114. Calculations. The Company will be responsible for making all
calculations called for under the Series G Senior 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 Series G Senior Notes and
Conversion Rate of the Series G Senior Notes. The Company 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
Company 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 Company's obligation to pay Contingent
Interest under Section 103(b) hereof, the Company 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

                                       28

<PAGE>

calculations on which such determination is based and setting forth the amount
of interest which will accrue on the Series G Senior 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 114. The
Trustee will forward the Company's calculations to any Holder upon the request
of such Holder.

     SECTION 115. Tax Treatment. The Company agrees, and by acceptance of
beneficial ownership interest in the Series G Senior Notes each beneficial
holder of Series G Senior Notes will be deemed to have agreed, for United States
federal income tax purposes (1) to treat the Series G Senior 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 Series G Senior Notes as a
contingent payment and (2) to be bound by the Company's determination of the
"comparable yield" and "projected payment schedule," within the meaning of the
Contingent Payment Regulations, with respect to the Series G Senior Notes. A
Holder of Series G Senior Notes may obtain the issue price, the amount of
original issue discount, issue date, yield to maturity, comparable yield and
projected payment schedule for the Series G Senior Notes by submitting a written
request for such information to the Company at the following address: Dominion
Resources, Inc., 120 Tredegar Street, Richmond, Virginia 23219, Attention:
Corporate Secretary.

     SECTION 116. Sinking Fund. The Series G Senior Notes shall not have a
sinking fund.

     SECTION 117. Additional Interest. Any principal of and installment of
interest on the Series G Senior Notes that is overdue shall bear interest at the
rate of 2.125% (to the extent that the payment of such interest shall be legally
enforceable), from the dates such amounts are due until they are paid or made
available for payment, and such interest shall be payable on demand.

     SECTION 118. Limitation on Liens. The Company will not, while any of the
Series G Senior Notes remain Outstanding, create, or suffer to be created or to
exist, any Lien upon any Principal Property of the Company or upon any shares of
stock of any Material Subsidiary of the Company, whether such Principal Property
is, or shares of stock are, now owned or hereafter acquired, to secure any
indebtedness for borrowed money of the Company, unless it shall make effective
provision whereby the Series G Senior Notes then Outstanding shall be secured by
such Lien equally and ratably with any and all indebtedness for borrowed money
thereby secured so long as any such indebtedness shall be so secured; provided,
however, that nothing in this Section shall be construed to prevent the Company
from creating, or from suffering to be created or to exist, any Liens, or any
agreements, with respect to:

     (a) purchase money mortgages, or other purchase money liens, pledges,
security interests or encumbrances of any kind upon property hereafter acquired

consolidation or merger of the Company or any Material Subsidiary of the Company
with or into any other Person (which may be an Affiliate of the Company or any

prior to, at the time of, or within 18 months after such acquisition (or in the
case of property constructed, developed or improved, after the completion of
such construction, development or improvement and commencement of full
commercial operation of such property, whichever is later) to secure or provide

payment, provided that any principal, and any such installment of interest, that
is overdue shall bear interest at the rate of 2.125% per annum (to the extent
that the payment of such interest shall be legally enforceable), from the dates
such amounts are due until they are paid or made available for payment, and such
interest shall be payable on demand. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Series G Senior Note
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be the close of
business on the Business Day preceding such Interest Payment Date; provided,
that with respect to Series G Senior Notes that are not represented by one or
more Global Securities, the Regular Record Date shall be the close of business
on the 15/th/ calendar day (whether or not a Business Day) preceding such
Interest Payment Date. Any such 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 Series G Senior Note (or
one or more Predecessor Securities) 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 Series G Senior Notes
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 on which the Series G Senior Notes may be listed, and upon
such notice as may be required by such exchange, all as more fully provided in
said Indenture.

         Payments of interest on the Series G Senior Notes will include interest
accrued to but excluding the respective Interest Payment Date, Redemption Date,
Put Date or Fundamental Change Purchase Date, as the case may be. Interest
payments for the Series G Senior 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 is payable on the Series G Senior Notes is not a Business Day, then
payment of the interest 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), in each case with the same force and effect as if made on the
date the payment was originally payable.

         Payment of the principal of and interest on this Series G Senior Note
will be made at the office of the Paying Agent, in the Borough of Manhattan,
City and State of New York, 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; provided, however, that at the option of the Company payment of
interest may be made (i) by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register or (ii) 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 Company on any date on or after
December 20, 2006 (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 on the principal amount to be redeemed to but
excluding the Redemption Date.

         Notice of any redemption by the Company will be mailed at least 20 days
but not more than 60 days before any Redemption Date to each Holder of
Securities of this series to be

                                       2

<PAGE>

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
Company 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 ption of the Company, 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 Company to purchase any
or all of the Securities of this series held by such Holder on December 15,
2006, December 15, 2008, December 15, 2013 and December 15, 2018 (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 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 25 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 Company 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 date designated by the Company that is no later than 30 days after
the date of the Company 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 to but excluding the Fundamental
Change Purchase Date upon delivery of a Fundamental Change Purchase Notice
containing the information set forth in the Indenture.

         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 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.

         Reference is hereby made to the further provisions of this Series G
Senior Note 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 referred to on the reverse hereof by manual signature, this Series G
Senior Note shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

                         REVERSE OF SERIES G SENIOR NOTE

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of June 1, 2000, as heretofore supplemented
and amended and as further supplemented by a Twenty-Third Supplemental Indenture
dated as of December 1, 2003 (collectively, as amended or supplemented from time
to time, herein called the "Indenture", which term shall have the meaning
assigned to it in such instrument), between the Company and JPMorgan Chase Bank
(formerly known as The Chase Manhattan Bank), as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), and
reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof (the "Series G Senior Notes"), which
is unlimited in aggregate principal amount.

         The Company shall pay Contingent Interest in cash to the Holders of the
Securities of this series in respect of any six-month period from June 15 to
December 14 and from December 15 to June 14, commencing with the six-month
period beginning December 15, 2006, 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 June 15 or December 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 Company shall provide
notice thereof to the Holders of the Securities.

         Subject to the procedures set forth in the Indenture, a Holder may
convert Securities of this series into Common Stock of the Company on or before
the close of business on December 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 March 31,
         2004 (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;

                  (b) to the extent that the Company calls this Security or any
         portion thereof for redemption, in the case of such Security or portion
         thereof, at any time prior to the close of business on the Business Day
         immediately preceding the Redemption Date;

                  (c) (1) if the Company 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 Company, which distribution has
         a per share value as determined by the Company's Board of Directors and
         set forth in a Board Resolution exceeding 5% 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 Company 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 Company 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 Company'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 Company becomes a party to a consolidation, merger,
         binding share exchange or transfer of all or substantially all its
         assets 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, if such consolidation, merger, share exchange or
         transfer of assets is a Fundamental Change, until the Fundamental
         Change Purchase Date); or

                  (d) during any period that (1) the long-term credit ratings
         assigned to the Securities of this series by both Moody's Investors
         Service, Inc. and Standard & Poor's Ratings Services are 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 Company 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 13.5865 shares of Common Stock per
$1,000 principal amount, subject to adjustment in certain events described in
the Indenture. The Company shall deliver cash in lieu of any fractional share of
Common Stock.

                                       7

         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 Company 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 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 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 Series G Senior Notes shall
occur and be continuing, the principal of the Series G Senior Notes may be
declared due and payable in the manner and with the effect 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
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains

                                       8

<PAGE>

provisions permitting the Holders of specified percentages 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 certain past defaults under
the Indenture and their consequences. Any such consent or waiver by the Holder
of this Series G Senior Note shall be conclusive and binding upon such Holder
and upon all future Holders of this Series G Senior Note and of any Series G
Senior Note issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Series G Senior Note.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Series G Senior Note shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or
trustee or for any other remedy thereunder, unless such Holder shall have
previously given the Trustee written notice of a continuing Event of Default
with respect to the Series G Senior Notes, the Holders of not less than a
majority in principal amount of the Series G Senior Notes at the time
Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity, and the Trustee shall not have received from the
Holders of a majority in principal amount of Series G Senior Notes at the time
Outstanding a direction inconsistent with such request, and shall have failed to
institute any such proceeding for 60 days after receipt of such notice, request
and offer of indemnity. The foregoing shall not apply to any suit instituted by
the Holder of this Series G Senior Note for the enforcement of any payment of
principal hereof or premium, if any, or interest hereon on or after the
respective due dates expressed or provided for herein.

         No reference herein to the Indenture and no provision of this Series G
Senior Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of, premium,
if any, and interest on this Series G Senior Note 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 Series G Senior Note is registrable in the
Security Register, upon surrender of this Series G Senior Note for registration
of transfer at the office or agency of the Company in any place where the
principal of, premium, if any, and interest on this Series G Senior Note are
payable, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Series G Senior Notes and of like tenor, of authorized denominations
and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

         The Company will be responsible for making all calculations called for
under the Series G Senior 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 Series G Senior Notes and Conversion Rate. The Company will
make these calculations in good faith and, absent manifest error, these
calculations will be final and binding on the Holders of the Series G Senior
Notes. Promptly after the calculation thereof, the Company 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 upon the accuracy of such calculations without

                                       9

<PAGE>

independent verification. The Trustee will forward the Company's calculations to
any Holder upon the request of such Holder.

         The Series G Senior Notes 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 certain limitations therein set forth,
Series G Senior Notes are exchangeable for a like aggregate principal amount of
Series G Senior Notes having the same Stated Maturity and of like tenor of any
authorized denominations as requested by the Holder upon surrender of the Series
G Senior Note or Series G Senior Notes to be exchanged at the office or agency
of the Company.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

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

         The Company 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 Company'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 Company at the
following address: Dominion Resources, Inc., 120 Tredegar Street, Richmond,
Virginia 23219, Attention: Corporate Secretary.

         All terms used in this Series G Senior Note that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.
