On December 19, 2007, The Children's  Investment  Fund  Management (UK) LLP, The
Children's  Investment Fund Management (Cayman) Ltd., The Children's  Investment
Master Fund, 3G Capital Partners Ltd., 3G Capital Partners,  L.P., 3G Fund L.P.,
Christopher Hohn, Alexandre Behring, Gilbert H. Lamphere, Timothy T. O'Toole and
Gary L. Wilson (collectively, the "Potential Participants") filed a Schedule 13D
("Schedule 13D") with the Securities  Exchange  Commission ("SEC") that included
Item 4 stating the following:

"PURPOSE OF TRANSACTION

The TCI  Reporting  Persons and the 3G  Reporting  Persons  originally  acquired
Shares for investment in the ordinary  course of business  because they believed
that the Shares, when purchased,  were undervalued and represented an attractive
investment  opportunity.  Messrs.  Lamphere and O'Toole acquired their Shares in
connection  with becoming  nominees to the board of directors of the Issuer (the
"Board").

After multiple  unsuccessful attempts to engage the management or the Board in a
constructive  dialogue  regarding the  operations of the Issuer,  on October 16,
2007,  the TCI Reporting  Persons  delivered a letter to the Board setting forth
numerous  failings  in  the  Issuer's   operations,   corporate  governance  and
management,  and asking the Board to take the  following  actions:  separate the
Chairman and CEO roles; refresh the Board with new independent directors;  allow
shareholders to call special shareholder meetings; align management compensation
with shareholder  interests;  justify the capital spending plan to shareholders;
and provide to shareholders a plan to improve  operations.  On October 22, 2007,
the TCI  Reporting  Persons sent a second  letter to the Board  criticizing  the
Board for  allowing  representatives  of the Issuer to describe  the Issuer as a
"public service company" in communications to policymakers in Washington, DC and
also  criticizing a statement made by the Issuer's CEO that no industry of which
he was aware analyzes returns on investment capital on a replacement cost basis.
A copy of the  October  16 and the  October 22 letters  are  attached  hereto as
Exhibits 2 and 3, respectively, and incorporated by reference herein.

The Reporting Persons currently intend to conduct a proxy  solicitation  seeking
to elect the  Nominees  to the Board at the  Issuer's  2008 Annual  Meeting.  On
December 12, 2007,  the TCI Reporting  Persons  delivered a letter to the Issuer
informing the Issuer of their intention to propose  nominees for election to the
Board at the Issuer's 2008 Annual Meeting and requesting  certain documents from
the Issuer required under the Issuer's bylaws to be completed by nominees to the
Board  in  order  to  comply  with  a  formal  notification  process  for  Board
nominations set forth in the Issuer's bylaws.

Except  as set forth  herein or as would  occur  upon  completion  of any of the
actions discussed herein, the Reporting Persons have no present plan or proposal
that would relate to or result in any of the matters set forth in  subparagraphs
(a)-(j) of Item 4 of Schedule 13D. The Reporting  Persons intend to review their
investments  in the Issuer on a continuing  basis and may engage in  discussions
with management,  the Board, other stockholders of the Issuer and other relevant
parties concerning the business, operations,  governance,  management,  strategy
and future plans





of the Issuer. Depending on various factors including,  without limitation,  the
Issuer's  financial  position  and  strategic  direction,  the  outcome  of  the
discussions  referenced above,  actions taken by the Board,  price levels of the
Shares,  other  investment  opportunities  available to the  Reporting  Persons,
conditions  in  the  securities   market  and  general   economic  and  industry
conditions,  the  Reporting  Persons  may in the future take such  actions  with
respect to their  investments in the Issuer as they deem appropriate  including,
without limitation,  purchasing  additional Shares or selling some or all of the
Shares  held by the  Reporting  Persons,  engaging  in short  selling  of or any
hedging or similar  transactions  with  respect to the Shares  and/or  otherwise
changing their intention with respect to any and all matters referred to in Item
4 of Schedule 13D."





Various materials have been posted to http://www.strongercsx.com. Copies of such
materials, current as of December 19, 2007, are filed herewith as Exhibit 1.

A copy of the press release issued in connection with the filing of the Schedule
13D is filed herewith as Exhibit 2.

Information regarding the Potential  Participants in a potential solicitation of
proxies with  respect to the Issuer's  2008 annual  meeting of  shareholders  is
filed herewith as Exhibit 3.





EXHIBIT 1
MOVING TOWARDS A STRONGER CSX

HOME

The Children's Investment Master Fund is a long-term, value-oriented investment
fund that is currently one of CSX's largest shareholders. In CSX, we see the
potential to be the leading railroad in the United States - providing the best
service, running the safest network, generating the highest returns, and being
able to meet America's freight transportation needs now and in the future.

CSX's legacy dates back to America's first railroad; it can be America's best.
This is in the interest of CSX employees, customers and shareholders.

We have a simple long-term desire: a stronger CSX.

IS MORE AN ISSUE OF MANAGEMENT."

ABOUT TCI

The Children's Investment Fund Management (UK) LLP ("TCI") is a London-based
asset manager founded in 2003 which manages The Children's Investment Master
Fund. TCI makes long-term investments in companies globally. The management
company is authorized and regulated in the United Kingdom by the Financial
Services Authority. A portion of TCI's profits go to The Children's Investment
Fund Foundation, a non-profit organization focused on improving the lives of
children living in poverty in developing countries.

INVESTMENT PHILOSOPHY

     TCI aims to bring a long-term, owner-oriented investing philosophy to the
     public markets. In keeping with and enabling this long-term horizon, TCI
     only raises capital that investors commit for multi-year periods.

     TCI employs a deep value, fundamentally-driven approach to identify
     attractive investments.

     TCI's portfolio is made up of large, concentrated investments based on
     proprietary research. TCI has spent two years of time and over $1 million
     in its effort to gain a superior understanding of CSX and the railroad
     industry as a whole.

     TCI seeks to maintain a constructive, open dialogue with management teams
     and Boards of the companies in which it invests. However, TCI has taken
     active roles in certain situations where it feels the Board and management
     are not acting in the best interests of shareholders. The majority of TCI's
     investors are American institutional investors, including a number of
     university endowments.

SHAREHOLDER ACTIVISM

     TCI has taken an active role in certain situations to promote sound
     corporate governance and increase shareholder value. TCI has been involved
     in the following disclosed investments:

     DEUTSCHE BORSE. After TCI's requests to allow shareholders to vote on the
     proposed acquisition of the London Stock Exchange were ignored, TCI
     successfully fought for board and subsequently management change. Deutsche
     Borse has since increased in value almost 400% and TCI continues to be a
     significant shareholder.

     ABN AMRO. After ABN had underperformed for years and failed to provide a
     clear strategy, TCI called for its break-up, merger or sale. TCI then
     successfully lobbied for an open process that would generate the best
     outcome for shareholders. As a result of this





     process, ABN agreed to be acquired by an RBS-led consortium at a 50%
     premium to its unaffected share price and at a significant premium to a
     competing offer.

     MITTAL STEEL AND ARCELOR. As a shareholder of both companies, TCI supported
     Mittal Steel in its unsolicited takeover offer for Arcelor. However, when
     Mittal Steel subsequently attempted to acquire Arcelor Brasil (one of
     Arcelor's subsidiaries) without an appropriate premium, TCI defended the
     rights of Arcelor Brasil's minority shareholders, causing Mittal to raise
     its offer price more than 55%.

PRINCIPALS INVOLVED IN RAILROAD INVESTMENTS

CHRIS HOHN, FOUNDER AND MANAGING PARTNER
Prior to founding TCI, Mr. Hohn was Portfolio Manager of Perry Capital's
European Fund. Mr. Hohn holds an MBA (high distinction) from Harvard Business
School.

SNEHAL AMIN, FOUNDING PARTNER
Previously, Mr. Amin was Vice President in Goldman Sachs' Merchant Banking
Division. Mr. Amin holds an MBA from Stanford University.

THE CHILDREN'S INVESTMENT FUND FOUNDATION

The Children's Investment Fund Foundation (CIFF) consists of two separate
charitable foundations incorporated in 2002, one in the US and one in the UK.
CIFF is an independent, non-profit, philanthropic organization that funds causes
to help better the lives of impoverished children in the developing world. Its
projects address basic needs like nutrition, education, sanitation and health.
CIFF receives a substantial portion of TCI's profits. For more information about
CIFF, please visit WWW.CIFF.ORG.

                                  CASE IN POINT

CSX's accident last week is case in point for why we can never sacrifice on
safety and shouldn't tolerate a management team that does. This time it was the
Anacostia River, but it could have been the Potomac. This time it was coal cars,
but it could have been chlorine tankers. This time there were no fatalities, but
there could have been thousands.

Cause of the accident? "Procedural error," otherwise known as management
failure.

"The brakes on the coal cars in the yard were not secured properly." Clearly a
mistake, and we all make mistakes, but the whole point of management procedures
is to make sure human mistakes don't translate to human tragedy.
This is not happening at CSX.

We have been openly critical of CSX's poor safety record, one area where we
don't want to get proven right. But the fact of the matter is, and the FRA said
as much in its post-investigation report in March, CSX's safety issues are
largely management related. Of course senior management cannot oversee every
action, or prevent every mistake, but they can implement procedures and promote
a safety culture that can go a long way towards doing so. This is also not
happening at CSX. Culture starts from the top, and a safety culture is no
different.

We believe a safety culture is based on motivation, not discipline. We believe
promoting for good behavior is more powerful than firing for bad behavior. We
believe fear is not as powerful a motivator as pride. We believe intimidation
has no place in any workplace, and certainly not in one where we are an owner.
We have seen reports, read testimony, and received emails from workers that
suggest CSX management is promoting a culture of fear and intimidation. That is
no way to manage, and it is no way to have to work.

Once again we call for improved rail labor relations, for constructive dialogue
instead of an us vs them mentality, and for a safe work environment that
employees can be proud of. It is better for safety, it is better for operations,
it is better for returns, and it is simply the right thing to do.

                                      ***

As we mentioned last time, we're always receptive to good ideas. We recently
spotted another one. This time from Tony Hatch, an independent railroad
consultant whose presence at railroad conferences is as common as regulators
around the world using replacement cost (i.e. very common!). Tony has suggested:





"PERHAPS UNVEILING A DUAL 2008 CAPEX BUDGET THIS YEAR END - ONE WITH A STABLE
'REGULATORY ENVIRONMENT AND ONE ASSUMING INSTABILITY OR A NEGATIVE ONE - MIGHT
DRIVE HOME THE RELATIONSHIP BETWEEN RETURNS AND CAPITAL EXPENDITURES TO
CONGRESS...".

                                   GOOD IDEAS

It has been over two weeks, and we still have not received any direct response
from the CSX management and Board. Is the company taking us seriously? Hard to
imagine it is when Michael Ward gives an interview with the Financial Times
where "he sarcastically dismissed the TCI's proposals as 'more good ideas.'"

It is disappointing (although not wholly surprising) that this management
doesn't consider improving corporate governance, improving safety, improving
service, improving operations, improving labor relations, improving shipper
relations, etc...as 'good ideas.'

What does CSX management consider a good idea? Apparently advertising the
company's significant exposure to housing in the middle of the worst housing
recession in decades, as it has been doing with full-page paid advertisements in
the Wall Street Journal...genius...

                                      ***

How is this for irony...

THE BALTIMORE AND OHIO (B&O), THE FIRST OF THE BIG RAILROADS, PIONEERED A NEW
LEVEL OF TRANSPARENCY. IT BEGAN WITH A FIVE-PAGE LETTER FROM THE PRESIDENT TO
THE INVESTORS IN THEIR FIRST YEAR OF CONSTRUCTION. THREE YEARS LATER, IT HAD
GROWN TO A 153-PAGE LETTER WITH 15 TABLES OF ACTUAL VS. BUDGETED CONSTRUCTION
COSTS. AFTER THEY BEGAN OPERATIONS, B&O MANAGEMENT PROVIDED REVENUES BY STATION
AND EXPENSES BY MONTH, AS WELL AS NET INCOME AND CASH FLOW. NOBODY TOLD B&O'S
MANAGERS THAT THEY HAD TO DO IT--NOT THE GOVERNMENT OR THE STOCKBROKERS OR "GOOD
GOVERNANCE" CRITICS. THEIR MANAGERS SIMPLY FIGURED THAT IF THEY WANTED THE CASH
NEEDED TO GROW THE BUSINESSES, THEY NEEDED TO MAKE THEIR INVESTORS AS
COMFORTABLE AS POSSIBLE. (Marc Hodak, as published in Forbes, October 25, 2007)

CSX traces its history back to the 1820s and a railroad called...yep, the
Baltimore and Ohio. It's one thing to have made no progress on corporate
governance and transparency, it's wholly another to be going backwards.

                                      ***

And lastly, it's always a good idea to ask the right questions. In our most
recent letter to the CSX Board we noted Michael Ward and Jim Young's contrasting
and revealing responses to a





question on whether they used replacement cost analysis (Jim Young - yes.
Michael Ward - no, and he doesn't know of any one else who does, by the way).

In our letter, we forgot to reference that it was Ken Hoexter, from Merrill
Lynch, who was responsible for those key questions. Good idea, Ken.

Friday October 26, 2007

MAY WE LIVE IN EXCITING TIMES...Last week certainly proved to be (for us at
least). In fact so much so that if we hadn't published our first letter early in
the week, all of the material CSX provided over the week would have resulted in
several more pages of letter. So we have decided to introduce our own blog - TCI
Fridays. Yes, we realize today is not Friday, but in honor of our investment we
thought it fitting that we not be on time.

We were not expecting a red-carpet reception to the CSX Board room, or to be
added to Michael Ward's Christmas card list, but we were not expecting `scorched
earth' either. CSX responded to our letter of October 16th in a way so
potentially damaging to CSX and other railroads that we found it necessary to
send another letter to the CSX Board. Michael Ward and his management team went
just short of calling CSX a non-profit (calling it a `public service company')
and denied the use of returns on replacement capital, only to be corrected the
next day by a fellow railroad CEO.

MICHAEL WARD "WHAT INDUSTRY LOOKS AT THE ROIC ON A REPLACEMENT COST BASIS? I
DON'T KNOW OF ANY INDUSTRY THAT DOES THAT."

JIM YOUNG, CEO OF UNION PACIFIC, THE NEXT DAY "WE LOOK INTERNALLY AT REPLACEMENT
COSTS WHEN WE'RE LOOKING AT HOW WE APPROACH A BUSINESS SEGMENT IN TERMS OF THE
COST NUMBERS."

We wouldn't have thought it necessary to provide a $36 million CEO with an
accounting lesson, but if that what it takes, that is what we will do. This
second letter is available at HTTP://WWW.STRONGERCSX.COM/CSXBOARDLETTEROCT22.PDF

Now to set the record straight - CSX HAS NOT HAD "NUMEROUS MEETINGS WITH TCI"
unless you count our attendance at CSX presentations, group meetings, or
(unintentionally) running into CSX management in a New York elevator bank. If
you consider, as we do, a "meeting" to be a one-on-one meeting with real
dialogue, there in fact have been no meetings between CSX and TCI. If you
exclude the criteria of real dialogue, then there has been only one meeting with
any CSX senior executive - a "listen only" meeting with Oscar Munoz (CFO), who
was accompanied by both his internal and external legal counsel. We have had no
meetings (by any definition) or even phone contact with the CSX Board.

Despite CSX's unwillingness to engage in constructive dialogue with us, we have
tried hard to share ideas with CSX management that we thought would enhance
CSX's long-term value. Under every layer we peeled and around every corner we
turned in our research of CSX and the US rail industry, we found an opportunity.
Opportunities ranged from improving safety to





bettering service to reducing the cost of capital. ONLY CSX WOULD CRITICIZE ONE
OF ITS SHAREHOLDERS FOR HAVING TOO MANY VALUE-CREATING IDEAS.

Is it unreasonable for a shareholder to question whether management should not
take advantage of CHEAP DEBT to finance investment, or whether it had even
considered whether a private equity transaction at a 50% premium made sense? Is
it unreasonable for a shareholder to question why management doesn't implement
ECP BRAKES, a technology which could cut braking distances by up to 60% and
thereby reduce accidents, increase capacity and generate 50% returns on capital?
Similarly, is it unreasonable for a shareholder to question why management isn't
more aggressive about implementation of POSITIVE TRAIN CONTROL, or other
technologies used around the world to enhance rail service and safety? The
United States is a global leader in technology adoption, why should our
railroads be such a glaring exception?

We do not think it is unreasonable to ask these questions. Nor do we think it is
unreasonable to question why CSX shareholders should tolerate poor corporate
governance and poor operating performance. These issues are not new, and neither
is our raising them.

"THE CSX MANAGEMENT AND BOARD HAVE BEEN UNABLE TO PROPERLY ANSWER OR, IN SOME
CASES, EVEN UNWILLING TO ENGAGE WITH US ON THE TOUGH QUESTIONS. THEY SEEM TO
THINK IT'S INAPPROPRIATE FOR SHAREHOLDERS TO CHALLENGE THEM. WELL WE MUST ASK
THE TOUGH QUESTIONS BECAUSE IT'S NOT CLEAR THAT THE BOARDS ARE."

We said this over five months ago in a public speech. Among the questions we
asked then were:

o    Why does CSX seem to consider it an accomplishment that its operating
     metrics are better than last year? Shouldn't it focus more on the fact that
     the gap in operating ratio between them and the leaders (CN and NSC) is
     actually widening?

o    Why doesn't CSX have explicit operational targets when it's clear that its
     operations are under-performing? The targeted operating ratio can be
     accomplished just with price, so does management not believe there is
     opportunity on the cost side?

o    Why does CSX say safety is a capex issue when it has 50% more human caused
     accidents per mile than NSC, and when 17 of the 20 safety faults the FRA
     highlighted were human errors or management failures? You don't need capex
     to put up the hand-brakes in railcars.

o    Why despite this performance, did the Board of CSX make Michael Ward the
     highest paid CEO in the industry ($36m in two years)?

Five months later, WE ARE STILL WAITING FOR ANSWERS. (We now understand how
shippers feel...)

One question has however been answered, by CSX's third quarter results. For the
first time since we have been asking management whether there was an opportunity
to improve





productivity, CSX management showed some signs of focus on productivity and cost
discipline. However, as Union Pacific's results proved only two days later,
WHATEVER CSX IS DOING IT CAN BE DONE BETTER. CSX's volumes fell 4% in the
quarter, and in that context they managed to keep their operating costs (ex-fuel
and depreciation) roughly flat (a marked improvement versus prior quarters where
volumes also fell and yet costs rose). Union Pacific not only managed to grow
volumes, but despite volume growth they managed to CUT costs by 2%. That is real
productivity. Over the past twelve months UP's operating costs per unit have
only grown 2.5%; CSX's have grown by a whopping 6%. With numbers like these, can
anybody argue we shouldn't expect more from CSX?

Interesting times indeed...

                 TCI AND 3G FORM GROUP OWNING 8.3% OF CSX SHARES
                    AND AN ADDITIONAL 11.8% ECONOMIC INTEREST

             PLAN TO NOMINATE MINORITY BOARD SLATE OF FIVE DIRECTORS
     -----------------------------------------------------------------------

NEW YORK, DECEMBER 19, 2007 - The Children's Investment Fund Management (UK) LLP
("TCI") and 3G Capital Partners, LTD. ("3G") today filed a Schedule 13D with the
Securities and Exchange Commission disclosing that they and several individuals
have formed a group ("Group") whose members own in the aggregate 8.3% of the
outstanding common shares of CSX Corporation (NYSE: CSX). The members of the
Group also hold derivative securities providing economic exposure equivalent to
an additional 11.8% of CSX's outstanding shares.

The filing also disclosed that the Group intends to nominate five directors for
election to the Board of Directors of CSX at its 2008 Annual Meeting of
Shareholders.

The Group believes its nominees will strengthen CSX's Board by adding strong
independent directors with a shareholder orientation, a broad range of railroad
and other relevant experience, and a firm commitment to improving CSX's
operating performance and corporate governance.

Christopher Hohn, Managing Partner of TCI, said, "CSX's incumbent Board has
overseen a railroad that for many years has lagged its peers on many of the key
metrics of operational and financial performance. Rather than engage in a
constructive dialogue with one of its largest shareholders, the CSX Board has
consistently ignored our substantive concerns and failed to hold management
accountable for continuing operational underperformance. Our goal is a strong
CSX that can provide the returns shareholders deserve, the service shippers
demand, a safety record communities can count on, and a working environment
employees can be proud of. To this end, we are nominating to the Board the
principals of two major shareholders and three distinguished independents with
meaningful railroad experience. We are committed to working constructively with
members of the Board to help improve CSX for the benefit of all of its
stakeholders."

The director nominees are:

>>   CHRISTOPHER HOHN
     Before founding TCI in 2003, Mr. Hohn spent seven years at Perry Capital
     and was the portfolio manager leading its European investment strategy from
     1997 to 2003. Mr. Hohn has previously served on the Board of RIT Capital
     Partners plc, which is publicly listed on the London Stock Exchange.

     Key reasons Mr. Hohn is being nominated and can add value to CSX are:





     o  Mr. Hohn has a long and successful track record of fundamental
        investing and actively  maximizing value of public companies,  including
        the Deutsche Borse Group, ABN AMRO, and Euronext N.V.
     o  Mr. Hohn has successfully advocated for strong corporate governance and
        shareholder rights in situations around the world.
     o  TCI owns approximately 4.2% of CSX's outstanding shares.

     Mr. Hohn received a B.S. degree in Accounting and Business Economics (1st
     Class Honors) from Southampton University and an M.B.A. degree (high
     distinction) from Harvard Business School.

     Latina Logistica (ALL), Latin America's largest independent railroad and
     logistics company, which operates more than 13,000 miles of track in Brazil
     and Argentina. He continues to serve on the Management Committee of ALL's
     Board.

     Key reasons Mr. Behring is being nominated and can add value to CSX are:

     o  Mr. Behring is a unique combination of a large CSX shareholder (3G owns
        approximately 4.1% of CSX's outstanding shares) and an experienced,
        accomplished, hands-on railroad executive.
     o  Under his leadership, ALL's accident rate was reduced by 86%,
        locomotive productivity increased at a double-digit compound annual
        growth rate, and its EBITDA margin improved from 6% to 42% through the
        third quarter 2007.
     o  ALL is now one of the most efficient and technologically advanced
        freight railroads in the world and has also been voted several times by
        its employees as one of the best companies to work for in Latin
        America.
     o  As a publicly traded company, ALL's market capitalization of $6.5
        billion is over 30 times the amount Mr. Behring and his partners paid
        for the company 10 years ago.

     Mr. Behring received a B.S. degree in Electric Engineering from Pontificia
     Universidade Catolica and an M.B.A. degree (high distinction) from Harvard

        successful and efficient railroads in North America.

        respectively.
     o  Mr. Lamphere is deeply knowledgeable of the best practices in railroad
        operations and a proven value-added railroad board director.

     Mr. Lamphere received an A.B. degree in Economics from Princeton University
     and an M.B.A. degree (high distinction) from Harvard Business School.

>>   TIMOTHY O'TOOLE

     Senior Vice President of Law and Government Affairs, Senior Vice President
     of Finance and Chief Financial Officer, Vice President and Treasurer, and
     Vice President and General Counsel.

     Key reasons Mr. O'Toole is being nominated and can add value to CSX are:

     o  Mr. O'Toole was a prominent figure in the transaction splitting the
        former Conrail business between CSX and Norfolk Southern, providing him
        with first-hand knowledge of CSX's assets and operations.
     o  Under his leadership, Conrail achieved record financial results and
        safety performance. Similarly, under his leadership the London
        Underground has improved service and safety and moved record numbers of
        passengers, all while undergoing an historic rebuilding program.
     o  Mr. O'Toole was made an Honorary Commander of the British Empire in
        recognition of his performance following the terrorist attack on
        London's transport system in 2005.

     Mr. O'Toole received a B.A. degree in English Literature (Maxima Cum Laude)
     from LaSalle University, a J.D. degree from the University of Pittsburgh
     School of Law, and an Honorary Doctor of Humane Letters degree from LaSalle

     Northwest Airlines from 1991 to 1997 and Chairman from 1997 to 2007. From
     1985 to 1990, he was Chief Financial Officer and a director of The Walt

     of Corporate Development, and Treasurer. He is a current director of Yahoo!

     Key reasons Mr. Wilson is being nominated and can add value to the CSX
     Board are:





     o  Mr. Wilson has a track record - as an executive, director and investor

        substantial shareholder value. He is also a strong advocate of improved
        corporate governance in public companies.

Beneficial Ownership of Common Stock and other Interests:

As of the close of  business  on  December  18,  2007,  New York City time,  the
Potential Participants  beneficially owned, in the aggregate,  35,054,952 shares
of  common  stock,  par  value  $1.00 per  share  (the  "Shares"),  representing
approximately   8.3%  of  the  Issuer's   outstanding  Shares  (based  upon  the
420,425,477 Shares outstanding,  which is the total number of Shares outstanding
as of September  28, 2007 as reported in the Issuer's  Quarterly  Report on Form
10-Q for the period ended September 28, 2007).

The TCI  Parties  share power to vote and direct the  disposition  of all of the
Shares held by the TCI Fund.  Thus, as of December 18, 2007, the TCI Parties may
be deemed to  beneficially  own (as that term is defined in Rule 13d-3 under the
Act) 17,796,998 Shares, or 4.2% of the outstanding  Shares. The 3G Parties share
power to vote and direct  the  disposition  of all of the Shares  held by the 3G
Fund.  Thus,  as of  December  19,  2007,  the  3G  Parties  may  be  deemed  to
beneficially  own (as  that  term  is  defined  in Rule  13d-3  under  the  Act)
17,232,854  Shares,  or 4.1% of the  outstanding  Shares.  Each Nominee has sole
power to vote or direct the disposition of the Shares he owns; thus,  Gilbert H.
Lamphere  has sole power to vote and direct the  disposition  of 22,600  Shares,
constituting less than 0.1% of the outstanding Shares and Timothy T. O'Toole has
sole power to vote and direct the disposition of 2,500 Shares, constituting less
than 0.1% of the outstanding Shares (which such Shares are held in an Individual
Retirement  Account in his name,  the  custodian  for which is  Citibank  Global
Markets, Inc.).

On  December  12,  2007,  TCIF UK and 3G  Capital  Ltd.  entered  into a  letter
agreement (the "Letter  Agreement") to coordinate  certain of their efforts with
regard to (i) the purchase and sale of common  shares  and/or  options  swaps or
other  derivative  instruments  that  constitute  or may by their  terms  create
beneficial  ownership  of  common  stock  of  the  Issuer   (collectively,   the
"Securities") held by TCIF UK, 3G Capital Ltd. and any investment funds, managed
accounts





and other investment  vehicles  managed or advised by either of them,  including
the other TCI Parties and the other 3G Parties and (ii) the  proposal of certain
actions and/or transactions to the Issuer.  Under the Letter Agreement,  certain
matters  will  require  mutual  agreement  of TCIF UK and 3G Capital  Ltd.:  (i)
whether  to run a proxy  contest  involving  the Issuer  and the  selection  and
nomination  of  individuals  to serve as  directors of the Issuer for such proxy
contest (as to which matters the TCIF UK and 3G Capital Ltd. have agreed),  (ii)
the making, revising or withdrawing of any proposals to the Issuer regarding the
conduct of its business, corporate governance matters, corporate transactions or
otherwise,  (iii) the admission or withdrawal of any  additional  members to the
Group (as defined  below)  being  formed by the Letter  Agreement,  and (iv) the
conduct of any litigation or  investigation if the same relates to the Group (as
defined below) conduct of the parties.

If the parties have agreed on a matter set forth in clauses  (i),  (ii) or (iii)
above,  TCIF  UK will  assume  decision-making  authority  with  respect  to the
execution of such matter, including with respect to (i) the conduct of any proxy
contest  involving the Issuer and (ii) the manner,  form,  content and timing of
any  communications  with the Issuer as well as any public  disclosures,  public
statements  or other third  party  communications  relating  to the Issuer,  the
Securities,  the Letter  Agreement and the activities of the TCI Parties and the
3G Parties pursuant thereto.

The Letter Agreement provides for certain shared and separate expenses,  as well
as termination  provisions  applicable  under certain  circumstances,  which are
specified  therein.  The  foregoing  description  of the Letter  Agreement  is a
summary only.

By virtue of the Letter  Agreement,  the TCI  Parties  and the 3G Parties may be
deemed to have formed a "Group"  within the  meaning of Section  13(d)(3) of the
Securities Act of 1934.  Furthermore,  the  Additional  Nominees may be deemed a
part  of  the   aforementioned   Group  by  virtue  of  the  contemplated  proxy
solicitation,  their agreement to be Additional  Nominees and their ownership of
Shares (as  applicable).  Collectively,  the Group may be deemed to have  voting
control  over a combined  8.3% of the Shares.  However,  each of the TCI Parties
expressly disclaims beneficial ownership of the Shares beneficially owned by the
3G Parties and the Additional  Nominees (as applicable),  each of the 3G Parties
expressly disclaims beneficial ownership of the Shares beneficially owned by the
TCI  Parties  and the  Additional  Nominees  (as  applicable),  and  each of the
applicable  Additional Nominees expressly disclaims  beneficial ownership of the
Shares  beneficially  owned by the 3G  Parties,  the TCI  Parties  and the other
Additional  Nominees.  Neither  the fact of this filing nor  anything  contained
herein  shall be deemed to be an admission by any of such parties that it is the
beneficial owner of any shares of Common Stock  beneficially owned by any of the
other parties, except as otherwise disclosed herein.

Messrs.  O'Toole and Wilson have each entered into a nominee agreement  pursuant
to which  the TCI Fund has  agreed  to pay the costs of  soliciting  proxies  in
connection with the Issuer's 2008 annual meeting of shareholders,  and to defend
and indemnify each of Messrs.  O'Toole or Wilson (as  applicable)  against,  and
with  respect  to, any  losses  that may be  incurred  by them in the event they
become  a party  to  litigation  based on their  nomination  as  candidates  for
election to the board of directors of the Issuer and the solicitation of proxies
in support of their  election.  Messrs.  Behring and Lamphere  have each entered
into a nominee  agreement  pursuant  to which the 3G Fund has  agreed to pay the
costs of soliciting  proxies in connection with the Issuer's 2008 annual meeting
of  shareholders,  and to defend  and  indemnity  each of  Messrs.  Behring  and
Lamphere (as  applicable)  against,  and with respect to, any losses that may be
incurred by them in the event they become a party to  litigation  based on their
nomination  as  candidates  for election to the board of directors of the Issuer
and the  solicitation  of proxies in support of their  election.  The Additional
Nominees do





not receive any compensation  under the nominee  agreements and will not receive
any  compensation  from  the  TCI  Parties,  the 3G  Parties  or  such  parties'
affiliates for their services as directors of the Issuer if elected. If elected,
the Additional Nominees will be entitled to such compensation from the Issuer as
is  consistent  with the Issuer's past  practices  for services of  non-employee
directors.

In  addition to the above,  partners or  employees  of the TCI  Parties,  the 3G
Parties and the Additional  Nominees may assist in the  solicitation  of proxies
and will receive no additional consideration therefore.
