No person has been authorized to give any information or to make any
representations other than those contained in this Company Notice and
accompanying Purchase Notice and, if given or made, such information or
representations must not be relied upon as having been authorized. This
Company Notice and accompanying Purchase Notice do not constitute an offer
to buy or the solicitation of an offer to sell securities in any
circumstances or jurisdiction in which such offer or solicitation is
unlawful. The delivery of this Company Notice shall not under any
circumstances, create any implication that the information contained herein
is current as of any time subsequent to the date of such information. None
of the Company or its board of directors or employees are making any
representation or recommendation to any Holder as to whether or not to
surrender such Holder's Securities. The Company recommends that you consult
your own financial and tax advisors with respect to tax consequences that
may vary on an individual basis, and you must make your own decision as to
whether to surrender your Securities for purchase and, if so, the amount of
Securities to surrender.



                             SUMMARY TERM SHEET

     The following are answers to some of the questions that you may have
about the Option. To understand the Option fully and for a more complete
description of the terms of the Option, we urge you to read carefully the
remainder of this Company Notice and the accompanying Purchase Notice
because the information in this summary is not complete and those documents
contain additional important information. We have included page references
to direct you to a more complete description of the topics in this summary.

     WHO IS OFFERING TO PURCHASE MY SECURITIES?

     SPX Corporation, a Delaware corporation (the "Company"), is offering
to purchase your validly surrendered Liquid Yield Option(TM) Notes due
February 6, 2021 (Zero Coupon-Senior) (the "Securities"). (Page 4)

     WHAT SECURITIES ARE YOU SEEKING TO PURCHASE?

     We are offering to purchase all of the Securities surrendered, at the
option of the holder thereof (the "Holder"). As of January 24, 2006, there
was approximately $994,692,000 aggregate principal amount at maturity of
Securities outstanding. The Securities were issued under an Indenture,
dated as of February 6, 2001 (the "Indenture"), between the Company and
JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank, a
national banking association organized and existing under the laws of the
United States of America (the "Paying Agent"). (Page 4)

     HOW MUCH ARE YOU OFFERING TO PAY AND WHAT IS THE FORM OF PAYMENT?

     Pursuant to the terms of the Indenture, we will pay, in cash, a
purchase price of $663.86 per $1,000 principal amount at maturity of the
Securities (the "Purchase Price") with respect to any and all Securities
validly surrendered for purchase and not withdrawn. (Page 4)

     HOW CAN I DETERMINE THE MARKET VALUE OF THE SECURITIES?

     There is no established reporting system or market for trading in the
Securities. To the extent that the Securities are traded, prices of the
Securities may fluctuate widely depending on trading volume, the balance
between buy and sell orders, prevailing interest rates, the Company's
operating results and the market for similar securities. To the extent
available, Holders are urged to obtain current market quotations for the
Securities prior to making any decision with respect to the Option. The
Common Stock, $10 par value per share (the "Common Stock") of SPX into
which the Securities are convertible is listed on the NYSE and the Pacific
Stock Exchange under the symbol "SPW". On January 24, 2006, the last
reported sales price of the Common Stock on the NYSE was $47.77 per share.
(Page 5)

     WHY ARE YOU MAKING THE OFFER?

     The Company is required to make the offer pursuant to the terms of the
Securities and the Indenture. (Page 4)

     WHAT DOES THE BOARD OF DIRECTORS FOR THE COMPANY THINK OF THE OPTION?

     Although the board of directors for the Company has approved the terms
of the Option included in the Indenture, the board of directors for the
Company has not made any recommendation as to whether you should surrender
your Securities for purchase in the offer. You must make your own decision
whether to surrender your Securities for purchase in the offer and, if so,
the amount of Securities to surrender. (Page 5)

     WHEN DOES THE OPTION EXPIRE?

     The Option expires at 5:00 p.m., New York City time, on February 6,
2006. The Company will not extend the period Holders have to accept the
Option. (Page 4)

     WHAT ARE THE CONDITIONS TO THE PURCHASE BY THE COMPANY OF THE
SECURITIES?

     The purchase by the Company of validly surrendered Securities is not
subject to any conditions other than such purchase being lawful. (Page 4)

     HOW DO I SURRENDER MY SECURITIES?

     To surrender your Securities for purchase pursuant to the Option, you

p.m., New York City time, on February 6, 2006.

     purchase, on or before 5:00 p.m. New York City time, on the Purchase
     Date.

  o  A Holder whose Securities are held by a broker, dealer, commercial
     bank, trust company or other nominee must contact such nominee if such
     Holder desires to surrender his or her Securities and instruct such
     nominee to surrender the Securities on the Holder's behalf.

     Securities by delivering to the Paying Agent's account at DTC through

     Securities on or before 5:00 p.m., New York City time, on the Purchase
     Date.

  o  Holders who are DTC participants should surrender their Securities
     electronically through DTC's Automated Tenders over the Participant
     Terminal System ("PTS"), subject to the terms and procedures of that
     system on or before 5:00 p.m., New York City time, on the Purchase
     Date. (Pages 6-7)

     IF I SURRENDER, WHEN WILL I RECEIVE PAYMENT FOR MY SECURITIES?

     We will accept for payment all validly surrendered Securities promptly
upon expiration of the Option. We will promptly forward to the Paying
Agent, prior to 10:00 a.m., New York City time, on February 7, 2006, the
appropriate amount of cash required to pay the Purchase Price for the
surrendered Securities, and the Paying Agent will promptly distribute the
cash to the Holders. (Page 7)

     UNTIL WHAT TIME CAN I WITHDRAW PREVIOUSLY SURRENDERED SECURITIES?

     You can withdraw Securities previously surrendered for purchase at any
time until 5:00 p.m., New York City time, on February 6, 2006. (Page 7)

     To withdraw previously surrendered Securities, you must deliver an
executed written notice of withdrawal substantially in the form attached,
or a facsimile of one, to the Paying Agent prior to 5:00 p.m., New York
City time, on February 6, 2006.

HOLDERS THAT WITHDRAW THROUGH DTC NEED NOT SUBMIT A PHYSICAL NOTICE OF
WITHDRAWAL TO THE PAYING AGENT IF SUCH HOLDERS COMPLY WITH THE WITHDRAWAL
PROCEDURES OF DTC. (Page 7)

     DO I NEED TO DO ANYTHING IF I DO NOT WISH TO SURRENDER MY SECURITIES
FOR PURCHASE?

     No. If you do not deliver a properly completed and duly executed
Purchase Notice before the expiration of the Option, we will not purchase
your Securities and such Securities will remain outstanding subject to
their existing terms. (Page 6)

     IF I CHOOSE TO SURRENDER MY SECURITIES FOR PURCHASE, DO I HAVE TO
SURRENDER ALL OF MY SECURITIES?

     No. You may surrender all of your Securities, a portion of your
Securities or none of your Securities for purchase. If you wish to
surrender a portion of your Securities for purchase, however, you must
surrender your Securities in a principal amount at maturity of $1,000 (the
"$1,000 principal amount") or an integral multiple thereof. (Page 6)

     IF I DO NOT SURRENDER MY SECURITIES FOR PURCHASE, WILL I CONTINUE TO
BE ABLE TO EXERCISE MY CONVERSION RIGHTS?

     Yes. If you do not surrender your Securities for purchase, your
conversion rights will not be affected. You will continue to have the right
to convert each $1,000 principal amount at maturity of a Security into
9.6232 shares of Common Stock (including preferred stock purchase rights)
of SPX, subject to the terms, conditions and adjustments specified in the
Indenture. (Page 5)

     IF I AM A U.S. RESIDENT FOR U.S. FEDERAL INCOME TAX PURPOSES, WILL I
HAVE TO PAY TAXES IF I SURRENDER MY SECURITIES FOR PURCHASE IN THE OPTION?

     The receipt of cash in exchange for Securities pursuant to the Option
will be a taxable transaction for U.S. federal income tax purposes and you
may recognize gain, income, loss or deduction. You should consult with your

                IMPORTANT INFORMATION CONCERNING THE OPTION

     1. INFORMATION CONCERNING THE COMPANY. SPX Corporation, a Delaware
corporation (the "Company" or "SPX"), is offering to purchase its Liquid
Yield Option(TM) Notes due February 6, 2021 (Zero Coupon-Senior) (the
"Securities").

     The Company maintains its registered and principal executive offices
at 13515 Ballantyne Corporate Place, Charlotte, North Carolina 28277. The
telephone number there is (704) 752-4400.

     2. INFORMATION CONCERNING THE SECURITIES. The Securities were issued
under an Indenture, dated as of February 6, 2001 (the "Indenture"), between
the Company and JPMorgan Chase Bank, N.A., formerly known as The Chase
Manhattan Bank, a national banking association organized and existing under
the laws of the United States of America (the "Paying Agent"). The
Securities mature on February 6, 2021.

     2.1. THE COMPANY'S OBLIGATION TO PURCHASE THE SECURITIES. Pursuant to
the terms of the Securities and the Indenture, unless earlier redeemed, the
Company is obligated to purchase all Securities validly surrendered for
purchase and not withdrawn, at the Holder's option on February 6, 2006 and
February 6, 2011. The purchase price will be $663.86 per LYON on February
6, 2006 and $761.00 per LYON on February 6, 2011.

     This Option will expire at 5:00 p.m., New York City time, on February
6, 2006 (the "Purchase Date"). The Company will not extend the period
Holders have to accept the Option. The purchase by the Company of validly
surrendered Securities is not subject to any conditions other than such
purchase being lawful.

     2.2. PURCHASE PRICE. Pursuant to the Indenture, the purchase price to
be paid by the Company for the Securities on February 6, 2006 is $663.86
per $1,000 principal amount at maturity of the Securities (the "Purchase
Price"). The Purchase Price will be paid in cash with respect to any and
all Securities validly surrendered for purchase and not withdrawn prior to
the Purchase Date. Securities surrendered for purchase will be accepted
only in principal amounts at maturity equal to $1,000 (the "$1,000
principal amount") or integral multiples thereof. The Original Issue
Discount (as defined in the Indenture) will cease to accrue on the Purchase
Date unless the Company defaults in making payment on Securities validly
surrendered for purchase and not withdrawn.

     The Purchase Price is based solely on the requirements of the
Indenture and the Securities and bears no relationship to the market price
of the Securities or the Common Stock. Thus, the Purchase Price may be
significantly higher or lower than the current market price of the
Securities. Holders of Securities are urged to obtain the best available
information as to potential current market prices of the Securities, to the
extent available, and the Common Stock before making a decision whether to
surrender their Securities for purchase.

     None of the Company or its board of directors or employees are making
any recommendation to Holders as to whether to surrender or refrain from
surrendering Securities for purchase pursuant to this Company Notice. Each
Holder must make his or her own decision whether to surrender his or her
Securities for purchase and, if so, the principal amount of Securities to
surrender based on such Holder's assessment of current market value of the
Securities and the Common Stock and other relevant factors.

     2.3. CONVERSION RIGHTS OF THE SECURITIES. The Securities are
convertible into SPX Common Stock (including preferred stock rights) in
accordance with and subject to the terms of the Indenture and paragraphs 9
and 10 of the Securities. The conversion rate of the Securities as of
February 6, 2006 is 9.6232 shares of Common Stock (including preferred
stock purchase rights) per $1,000 principal amount of the Securities. The
Paying Agent is currently acting as Conversion Agent for the Securities.

     Holders that do not surrender their Securities for purchase pursuant
to the Option will maintain the right to convert their Securities into
Common Stock (including preferred stock purchase rights), subject to the
terms, conditions and adjustments specified in the Indenture. Any
Securities as to which a Purchase Notice has been given may be converted in
accordance with the terms of the Indenture only if the applicable Purchase
Notice has been validly withdrawn prior to 5:00 p.m., New York City time,
on the Purchase Date, as described in Section 4 hereto.

     2.4. MARKET FOR THE SECURITIES AND SPX COMMON STOCK. There is no
established reporting system or trading market for trading in the
Securities. To the extent that the Securities are traded, prices of the
Securities may fluctuate widely depending on trading volume, the balance
between buy and sell orders, prevailing interest rates, the Company's
operating results and the market for similar securities. To the extent
available, Holders are urged to obtain current market quotations for the
Securities prior to making any decision with respect to the Option. The
Securities are held through The Depository Trust Company ("DTC"). As of
January 24, 2006, there was approximately $994,692,000 aggregate principal
amount at maturity of Securities outstanding and DTC was and is the sole
record holder of the Securities.

     The Common Stock of SPX into which the Securities are convertible is
listed on the NYSE and the Pacific Stock Exchange under the symbol "SPW."
The following table sets forth, for the fiscal quarters indicated, the high
and low sales prices of the Common Stock as reported on the NYSE. This
table gives effect to the October 24, 2002 two-for-one split of the Common
Stock of SPX.

     In December 2003, the board of directors for the Company approved the
implementation of a quarterly dividend program that began in 2004. Pursuant
to the program, the Company expects to declare a quarterly dividend payable
early in each fiscal quarter. The first dividend was paid early in the
second quarter 2004. The board of directors for the Company approved an
initial target quarterly dividend level of $0.25 per share. The actual
amount of each quarterly dividend, as well as each declaration date, record
date and payment date, is subject to the discretion of the board of
directors for the Company, and the target dividend level may be adjusted
during the year at the discretion of the board of directors for the
Company. The factors the board of directors for the Company is expected to
consider in determining the actual amount of each quarterly dividend will
include the Company's financial performance and on-going capital needs, its
ability to declare and pay dividends under the terms of its credit facility
and indenture, and other factors deemed relevant.

     On January 24, 2006, the last reported sales price of the Common Stock
on the NYSE was $47.77 per share. As of such date, there were approximately
60,512,853 shares of Common Stock outstanding. We urge you to obtain
current market information for the Securities, to the extent available, and
the Common Stock before making any decision to surrender your Securities
pursuant to the Option.

     2.5. REDEMPTION. The Securities are not redeemable by the Company
prior to February 6, 2006. Beginning on February 6, 2006, the Securities
are redeemable for cash at any time at the option of the Company, in whole
or in part, at a redemption price equal to the Issue Price (as defined in
the Indenture) plus accrued Original Issue Discount (as defined in the
Indenture and as provided for in the Securities) to the date of redemption.

     2.6. CHANGE IN CONTROL. The Holder may require the Company to redeem
his or her securities if there is a Change in Control (as defined in the
Indenture) at a redemption price equal to the Issue Price (as defined in
the Indenture) plus accrued Original Issue Discount (as defined in the
Indenture) to the date of redemption.

     2.7. RANKING. The Securities are unsecured and unsubordinated
obligations of the Company. The Securities rank equal in right of payment
with all of the Company's existing and future unsecured and unsubordinated
indebtedness. The Securities are effectively subordinated to all existing
and future indebtedness and other liabilities of the Company's subsidiaries
and to the Company's obligations that are secured to the extent of the
security, including the indebtedness under the Company's amended and
restated credit agreement.

     3. PROCEDURES TO BE FOLLOWED BY HOLDERS ELECTING TO SURRENDER
SECURITIES FOR PURCHASE. Holders will not be entitled to receive the
Purchase Price for their Securities unless they validly surrender and do
not withdraw the Securities on or before 5:00 p.m., New York City time, on
the Purchase Date. Only registered Holders are authorized to surrender
their Securities for purchase. Holders may surrender some or all of their
Securities; however, any Securities surrendered must be in $1,000 principal
amount or an integral multiple thereof.

     If Holders do not validly surrender their Securities on or before 5:00
p.m., New York City time, on February 6, 2006, their Securities will remain
outstanding subject to the existing terms of the Securities.

     3.1. METHOD OF DELIVERY. The method of delivery of Securities, the
related Purchase Notice and all other required documents, including
delivery through DTC and acceptance through DTC's Automatic Tenders over
the Participant Terminal System ("PTS"), is at the election and risk of the
person surrendering such Securities and delivering such Purchase Notice
and, except as expressly otherwise provided in the Purchase Notice,
delivery will be deemed made only when actually received by the Paying
Agent. The date of any postmark or other indication of when a Security or
the Purchase Notice was sent will not be taken into account in determining
whether such materials were timely received. If such delivery is by mail,
it is suggested that Holders use properly insured, registered mail with
return receipt requested, and that Holders mail the required documents
sufficiently in advance of the Purchase Date to permit delivery to the
Paying Agent prior to 5:00 p.m., New York City time, on February 6, 2006.

     3.2. PURCHASE NOTICE. Pursuant to the Indenture, the Purchase Notice
must contain:

  o  the certificate number of the Securities being delivered for purchase;

  o  the portion of the principal amount of the Securities which will be
     delivered to be purchased, which portion must be in principal amounts
     of $1,000 at maturity or an integral multiple thereof; and

  o  a statement that such Securities shall be purchased as of the Purchase
     Date pursuant to the terms and conditions specified in the Indenture
     and paragraph 7 of the Securities.

     3.3. DELIVERY OF SECURITIES.

     Securities in Certificated Form. To receive the Purchase Price,
Holders of Securities in certificated form must deliver to the Paying Agent
the Securities to be surrendered for purchase and the accompanying Purchase
Notice, or a copy thereof, on or before 5:00 p.m., New York City time, on
the Purchase Date.

     Securities Held Through a Custodian. A Holder whose Securities are
held by a broker, dealer, commercial bank, trust company or other nominee
must contact such nominee if such Holder desires to surrender his or her
Securities and instruct such nominee to surrender the Securities for
purchase on the Holder's behalf.

     Securities in Global Form. A Holder who is a DTC participant may elect
to surrender to the Company his or her beneficial interest in the
Securities by:

  o  delivering to the Paying Agent's account at DTC through DTC's
     book-entry system his or her beneficial interest in the Securities on
     or prior to 5:00 p.m., New York City time, on the Purchase Date; and

  o  electronically transmitting his or her acceptance through DTC's PTS,
     subject to the terms and procedures of that system on or prior to 5:00
     p.m., New York City time, on the Purchase Date. In surrendering
     through PTS, the electronic instructions sent to DTC by the Holder,
     and transmitted by DTC to the Paying Agent will acknowledge, on behalf
     of DTC and the Holder, receipt by the Holder of and agreement to be
     bound by the Purchase Notice.

     SECURITIES AND THE PURCHASE NOTICE MUST BE DELIVERED TO THE PAYING
AGENT TO COLLECT PAYMENT. DELIVERY OF DOCUMENTS TO DTC OR THE COMPANY DOES
NOT CONSTITUTE DELIVERY TO THE PAYING AGENT.

HOLDERS THAT SURRENDER THROUGH DTC NEED NOT SUBMIT A PHYSICAL PURCHASE
NOTICE TO THE PAYING AGENT IF SUCH HOLDERS COMPLY WITH THE TRANSMITTAL
PROCEDURES OF DTC.

     4. RIGHT OF WITHDRAWAL. Securities surrendered for purchase may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the
Purchase Date. In order to withdraw Securities, Holders must deliver to the
Paying Agent written notice, substantially in the form enclosed herewith,
containing:

  o  the certificate number(s) and principal amount at maturity of the
     Securities with respect to which such notice of withdrawal is being
     submitted;

  o  the principal amount at maturity, if any, of such Securities which
     remain subject to the original Purchase Notice and which have been or
     will be delivered for purchase by the Company; and

  o  the Holder's signature, in the same manner as the original signature
     on the Purchase Notice by which such Securities were surrendered for
     purchase.

     The signature on the notice of withdrawal must be guaranteed by an
Eligible Guarantor Institution (as defined in Rule 17Ad-15 of the Exchange
Act) unless such Securities have been surrendered for purchase for the
account of an Eligible Guarantor Institution. Any properly withdrawn
Securities will be deemed not validly surrendered for purposes of the
Option. Securities withdrawn from the Option may be resurrendered by
following the surrender procedures described in Section 3 above.

HOLDERS THAT WITHDRAW THROUGH DTC NEED NOT SUBMIT A PHYSICAL NOTICE OF
WITHDRAWAL TO THE PAYING AGENT IF SUCH HOLDERS COMPLY WITH THE WITHDRAWAL
PROCEDURES OF DTC.

     5. PAYMENT FOR SURRENDERED SECURITIES. We will promptly forward to the
Paying Agent, prior to 10:00 a.m., New York City time, on February 7, 2006
the appropriate amount of cash required to pay the Purchase Price for the
surrendered Securities, and the Paying Agent will promptly distribute the
cash to each Holder that has validly delivered its Securities and not
validly withdrawn such delivery prior to 5:00 p.m., New York City time, on
the Purchase Date.

     The total amount of funds required by the Company to purchase all of
the Securities is approximately $660.3 million (assuming all of the
Securities are validly surrendered for purchase and accepted for payment).
In the event any Securities are surrendered and accepted for payment, the
Company intends to use cash to purchase the Securities. The Company does
not have an alternative financing plan at this time.

     6. SECURITIES ACQUIRED. Any Securities purchased by the Company
pursuant to the Option will be cancelled by the Trustee, pursuant to the
terms of the Indenture.

     7. PLANS OR PROPOSALS OF THE COMPANY. The Company currently has no
plans which would be material to a Holder's decision to surrender
Securities for purchase in the Option, which relate to or which would
result in:

  o  any extraordinary transaction, such as a merger, reorganization or
     liquidation, involving the Company or any of its subsidiaries;

  o  any purchase, sale or transfer of a material amount of assets of the
     Company or any of its subsidiaries;

  o  any material change in the present dividend rate or policy, or
     indebtedness or capitalization of the Company;

  o  any change in the present board of directors or management of the
     Company, including, but not limited to, any plans or proposals to
     change the number or the term of directors or to fill any existing
     vacancies on the board or to change any material term of the
     employment contract of any executive officer;

  o  any other material change in the corporate structure or business of
     the Company;

  o  any class of equity securities of the Company to be delisted from a
     national securities exchange or cease to be authorized to be quoted in
     an automated quotation system operated by a national securities
     association;

  o  any class of equity securities of the Company becoming eligible for
     termination of registration under Section 12(g)(4) of the Securities
     Exchange Act of 1934, as amended (the "Exchange Act");

  o  the suspension of the obligation of the Company to file reports under
     Section 15(d) of the Exchange Act;

  o  the acquisition by any person of additional securities of the Company,
     or the disposition of securities of the Company; or

  o  any changes in the charter, bylaws or other governing instruments of
     the Company, or other actions that could impede the acquisition of
     control of the Company.

     8. INTERESTS OF DIRECTORS, EXECUTIVE OFFICERS AND AFFILIATES OF THE
COMPANY IN THE SECURITIES. EXCEPT AS OTHERWISE DISCLOSED BELOW, TO THE
KNOWLEDGE OF THE COMPANY:

  o  none of the Company, or its executive officers, directors,
     subsidiaries or other affiliates has any beneficial interest in the
     Securities;

  o  none of the officers or directors of the subsidiaries of the Company
     has any beneficial interest in the Securities;

  o  the Company will not purchase any Securities from such persons; and

  o  during the 60 days preceding the date of this Company Notice, none of
     such officers, directors or affiliates has engaged in any transactions
     in the Securities.

     A list of the directors and executive officers of SPX is attached to
this Company Notice as Annex A.

     9. PURCHASES OF SECURITIES BY THE COMPANY AND ITS AFFILIATES. Each of
the Company and its affiliates, including their executive officers and
directors, is prohibited under applicable United States federal securities
laws from purchasing Securities (or the right to purchase Securities) other
than through the Option until at least the tenth business day after the
Purchase Date. Following such time, if any Securities remain outstanding,
the Company and its affiliates may purchase Securities in the open market,
in private transactions, through a subsequent tender offer, or otherwise,
any of which may be consummated at purchase prices higher or lower than the
Purchase Price. Any decision to purchase Securities after the Option, if
any, will depend upon many factors, including the market price of the
Securities, the amount of Securities surrendered for purchase pursuant to
the Option, the market price of the Common Stock, the business and
financial position of the Company, and general economic and market
conditions.

     10. MATERIAL UNITED STATES TAX CONSIDERATIONS.

     U.S. Federal Income Tax Considerations. The following discussion is a
summary of the material U.S. federal income tax considerations relating to
the surrender of Securities for purchase pursuant to the Option. This
discussion does not purport to be a complete analysis of all potential tax
effects of the Option. This summary is based upon laws, regulations,
rulings and decisions currently in effect, all of which are subject to
change or differing interpretations at any time, possibly with retroactive
effect. Moreover, this summary applies only to Holders who hold Securities
as "capital assets" within the meaning of Section 1221 of the Internal
Revenue Code of 1986, as amended (the "Code"), and does not purport to deal
with persons in special tax situations, such as financial institutions,
insurance companies, regulated investment companies, tax exempt investors,
dealers in securities and currencies, U.S. expatriates, persons holding
Securities as a position in a "straddle," "hedge," "conversion" or other
integrated transaction for tax purposes, persons who own, directly or
indirectly, 10% or more of SPX's voting power, or U.S. Holders (as defined
below) whose functional currency is not the U.S. dollar. Further, this
discussion does not address the consequences under U.S. federal estate or
gift tax laws or the laws of any U.S. state or locality or any foreign
jurisdiction.

     For purposes of this discussion, a "U.S. Holder" means a beneficial
owner of Securities that is, for U.S. federal income tax purposes: a
citizen or resident of the United States as defined in Section 7701 of the
Code; a corporation (or other entity treated as a corporation for U.S.
federal income tax purposes) created or organized in or under the laws of
the United States or any political subdivision thereof; an estate the
income of which is subject to U.S. federal income tax regardless of its
source; a trust if a court within the United States is able to exercise
primary jurisdiction over its administration and one or more U.S. persons
have authority to control all of its substantial decisions. As used herein,
the term "non-U.S. Holder" means a beneficial owner of Securities, other
than a partnership, that is not a U.S. Holder as defined above. The tax
treatment of a partnership that holds Securities will generally depend on
the status of the partners and the activities of the partnership. Holders
that are partnerships should consult their own tax advisors about the U.S.
federal income tax consequences of surrendering Securities pursuant to the
Option.

     Sale of Securities Pursuant to the Option. A U.S. Holder who receives
cash in exchange for Securities pursuant to the Option will recognize
taxable gain or loss equal to the difference between (i) the amount of cash
received, and (ii) the U.S. Holder's adjusted tax basis in the Securities
surrendered.

     A U.S. Holder will have an adjusted tax basis in the Securities that
will generally be equal to the U.S. Holder's purchase price for the
Securities, increased by any interest income previously accrued by the U.S.
Holder, and increased or decreased by the amount of any positive or
negative adjustment, respectively, that a U.S. holder has made as a result
of a purchase of a Security for an amount other than the adjusted issue
price, all as determined under the special regulations governing contingent
payment debt instruments (the "CPDI regulations"). Under the CPDI
regulations, the adjusted issue price is the issue price of a Security
increased by any interest income previously accrued, determined without
regard to any adjustment described above. The issue price of a Security is
the first price at which a substantial amount of the Securities were sold
to the public, excluding bond houses, brokers or similar persons or
organizations acting in the capacity of underwriters, placement agents or
wholesalers.

     The CPDI regulations are complicated. Each Holder should consult a tax
adviser regarding the accrual of interest, any positive and negative
adjustments, and the calculation of adjusted tax basis with respect to each
Holder's Securities.

     Gain recognized upon the surrender of Securities for cash pursuant to
the Option will generally be treated as ordinary interest income; any loss
will be ordinary loss to the extent of interest previously included in
income, and thereafter, capital loss (which will be long-term if the
Securities are held for more than one year). The deductibility of net
capital losses by individuals and corporations is subject to limitations.

     A non-U.S. Holder who receives cash in exchange for Securities
pursuant to the Option generally will not be subject to U.S. federal income
tax on any gain recognized, provided that: (i) such non-U.S. Holder does
not own, actually or constructively, 10 percent or more of the total
combined voting power of all classes of the Company's stock entitled to
vote, is not a controlled foreign corporation related, directly or
indirectly, to the Company through stock ownership, and is not a bank
receiving interest described in section 881(c)(3)(A) of the Code; (ii) the
non-U.S. Holder certifies on IRS Form W-8BEN, under penalties of perjury,
that it is not a United States person and provides its name and address;
(iii) such non-U.S. Holder is not an individual who is present in the
United States for 183 days or more in the taxable year of disposition, or
such individual does not have a "tax home" (as defined in section 911(d)(3)
of the Code) or an office or other fixed place of business in the United
States; and (iv) such gain is not effectively connected with the conduct by
such non-U.S. Holder of a trade or business in the United States.

     If a non-U.S. Holder of the Securities is engaged in a trade or
business in the United States, and if the gain on the notes is effectively
connected with the conduct of such trade or business, the non-U.S. Holder,
although exempt from the withholding tax discussed in the preceding
paragraphs, will generally be subject to regular U.S. federal income tax on
any gain realized on the sale or exchange of the Securities in the same
manner as if it were a U.S. Holder. In lieu of the certificate described in
the preceding paragraph, such a non-U.S. Holder will be required to provide
to the withholding agent a properly executed IRS Form W-8ECI (or successor
form) in order to claim an exemption from withholding tax. In addition, if
such a non-U.S. Holder is a foreign corporation, such Holder may be subject
to a branch profits tax equal to 30% (or such lower rate provided by an
applicable treaty) of its effectively connected earnings and profits for
the taxable year, subject to certain adjustments.

     Backup Withholding. Under the backup withholding provisions of the
Code, a U.S. Holder who surrenders Securities for purchase will generally
be subject to backup withholding at the rate of 28% of any gross payment if
such Holder fails to provide properly completed Form W-9 (or other
acceptable substitute). U.S. Holders electing to surrender Securities
should complete the Form W-9 which is part of the Purchase Notice and
provide it with the Securities being surrendered. If you are a U.S. Holder
exempt from backup withholding under the Code, please so indicate in the
Form W-9. If a non-U.S. Holder holds Securities through the non-U.S. office
of a non-U.S. related broker or financial institution, backup withholding
and information reporting generally will not be required. Information
reporting, and possibly backup withholding, may apply if the Securities are
held by a non-U.S. Holder through a U.S. broker or financial institution or
the U.S. office of a non-U.S. broker or financial institution and the
non-U.S. Holder fails to provide appropriate information (on Form W-8BEN or
other applicable form). Non-U.S. Holders should consult their tax advisors
with respect to the application of U.S. information reporting and backup
withholding rules to the disposition of Securities pursuant to the Option.

     THE COMPANY RECOMMENDS THAT HOLDERS CONSULT WITH THEIR TAX AND
FINANCIAL ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES THAT MAY VARY ON AN
INDIVIDUAL BASIS, BEFORE SURRENDERING THEIR SECURITIES FOR PURCHASE.
