               THE SOUTH FINANCIAL GROUP TO ACQUIRE MOUNTAINBANK;
                   EXPANDS INTO WESTERN NORTH CAROLINA MARKETS

GREENVILLE, SC - The South Financial Group, Inc. (Nasdaq: TSFG) today announced
a definitive agreement to acquire MountainBank Financial Corporation (Nasdaq:
MBFC) in an all stock transaction valued at approximately $137 million.
MountainBank, the largest community bank headquartered in Western North
Carolina, operates 18 branch offices in 10 counties with approximately $850
million in assets.

MountainBank has the #2 deposit market share in Henderson County, with 24% of
the market, and an expanding presence in attractive Western North Carolina
markets, including Asheville. Immediately following the merger, MountainBank's
banking subsidiary will retain the MountainBank name.

"The merger with MountainBank fits solidly with our disciplined acquisition
criteria," said Mack I. Whittle, Jr., President and Chief Executive Officer of
The South Financial Group. "As previously stated, we will only do mergers that
enhance our geographic franchise and are accretive to our financial goals.
MountainBank exceeds these standards. We expect the merger to be accretive to
both GAAP and cash earnings per share in the first full year and to enhance our
financial and strategic goals. We have similar banking cultures, ones that
emphasize superior customer service and knowing our customers well."

Whittle continued, "The Hendersonville and Asheville markets are strong, growing
markets, which we have targeted for expansion for many years. It's a logical
extension of our franchise into neighboring communities. Many of our existing
customers have vacation homes in these attractive mountain communities. Plus, we
bring a track record of successful operations in resort communities from our
experience in the coastal Carolinas and Florida. The MountainBank merger fits
extremely well with what we already do and where we already are, while advancing
our focus on profitability."

J. W. Davis, President and Chief Executive Officer of MountainBank, who will
join the TSFG Board of Directors, said, "We are excited to be joining The South
Financial Group. Our companies bring a shared commitment to our customers and
our communities. MountainBank expresses this philosophy with its tag line,
`Taking care of our own.' The South Financial Group shares this operating



philosophy, which will make for an outstanding partnership. In keeping with our
original commitment to shareholders, we are extremely pleased that over the past
five and one half years we have produced superior returns to our charter
shareholders. This strategic alignment greatly enhances our shareholders'
liquidity and provides them with continued long-term investment value."

MountainBank shareholders will receive $32.50 per MountainBank common share,
payable in TSFG common stock. The TSFG common stock will be valued based upon
the 10-day trading average immediately subsequent to Federal Reserve consent,
subject to pricing collars. In the merger, TSFG expects to issue approximately
5.5 million shares of common stock for all the common stock, preferred stock and
stock obligations of MountainBank, based on current market prices. The
transaction, which is expected to close in October 2003, is subject to
regulatory and MountainBank shareholder approvals.

Assuming expense savings of 20%, TSFG anticipates that the merger will be
accretive in the first year. This estimate does not include any anticipated
revenue enhancements. TSFG expects to incur pre-tax merger charges of
approximately $13 million. The transaction is valued at approximately 2.4x
MountainBank's book value at March 31, 2003 and 20.4x earnings for the
last-twelve-months through March 31, 2003.

The South Financial Group, headquartered in Greenville, South Carolina, is a
financial services company with approximately $9.0 billion in total assets and
115 branch offices in South Carolina, Florida, and North Carolina. It operates
two subsidiary banks: Carolina First Bank and Mercantile Bank. Carolina First
Bank, the largest South Carolina-based commercial bank, operates in South
Carolina, North Carolina, and on the internet under the brand name, Bank
CaroLine. Mercantile Bank operates in Florida, principally in the Jacksonville,
Orlando, and Tampa Bay markets. The South Financial Group's common stock trades
on the Nasdaq National Market under the symbol TSFG. Press releases along with
additional information may also be found at The South Financial Group's web

         This press release contains financial information determined by methods
other than in accordance with Generally Accepted Accounting Principles ("GAAP").
The South Financial Group's management uses these non-GAAP measures in their
analysis of TSFG's performance. In particular, a number of measures presented
adjust GAAP information to exclude the effects of non-operating item (such as
merger-related costs, gains or losses on asset sales, and non-operating
expenses) and the amortization of intangibles for "cash basis" performance
measures. Since these items and their impact on TSFG's performance are difficult
to predict, management believes presentations of financial measures excluding
the impact of these items provide useful supplemental information that is
essential to a clear understanding of the operating results of TSFG. These
disclosures should not be viewed as a substitute for GAAP operating results, and
furthermore TSFG's non-GAAP measures may not necessarily be comparable to
non-GAAP performance measures of other companies.
         Certain matters set forth in this news release may contain
forward-looking statements that are provided to assist in the understanding of
anticipated future financial performance. These statements, as well as other
statements that may be made by management in the conference call, include, but
are not limited to, factors which may affect earnings, expected financial
results for the MountainBank merger, estimates of merger-related cost savings
and charges, and credit quality assessment. However, such performance involves
risks and uncertainties, such as market deterioration, that may cause actual
results to differ materially from those in such statements. For a discussion of
certain factors that may cause such forward-looking statements to differ
materially from TSFG's actual results, see TSFG's Quarterly Report on Form 10-Q
for the quarter ended March 31, 2003. TSFG undertakes no obligation to release
revisions to these forward-looking statements or reflect events or circumstances
after the date of this release.
         The foregoing may be deemed to be offering materials of TSFG in
connection with TSFG's proposed acquisition of MountainBank, on the terms and
subject to the conditions in the Agreement and Plan of Merger, dated May 14,
2003, between TSFG and MountainBank. This disclosure is being made in connection
with Regulation of Takeovers and Security Holder Communications (Release Nos.
33-7760 and 34-42055) adopted by the Securities and Exchange Commission ("SEC").
Shareholders of MountainBank and other investors are urged to read the proxy
statement/prospectus that will be included in the registration statement on Form
S-4, which TSFG will file with the SEC in connection with the proposed merger
because it will contain important information about TSFG, MountainBank, the

Transcript from Conference Call/Web Cast, May 15, 2003, 10:00 a.m. ET

THE OPERATOR: Good morning and welcome to the South Financial Group announcement
of the MountainBank  acquisition.  All participants  will be able to listen only
until the question and answer  session.  At that time you will be instructed how
to ask a  question.  This  conference  is being  recorded.  Should  you have any
objections  you may  disconnect.  I would now like to introduce your host today,
Mr. Bill Hummers, Principal Financial Officer of The South Financial Group. Sir,
you may begin. MR. WILLIAM HUMMERS:  Thank you and good morning.  Welcome to The
South  Financial  Group  call  on  the  acquisition  of  MountainBank  Financial
Corporation.   Before  we  begin,  I  would  like  to  make  a  statement  about
forward-looking    statements   in   non-GAAP   financial    information.    The
forward-looking   statements   being  made  today  are   subject  to  risks  and
uncertainties. TSFG actual results may differ materially from those set forth in
such  forward-looking  statements.  References made to TSFG's reports filed with
the Securities  and Exchange  Commission for the discussion of factors which may
cause such  differences to occur.  This  presentation  contains certain non-GAAP
measures which TSFG management uses in our analysis of TSFG's performance. These
measures  typically adjust GAAP measures to exclude the effects of non-operating
items such as  merger-related  costs and gains or losses on asset  sales and the
amortization  of  intangibles  for  cash  basis  performance   measures.   These
disclosures  should not be viewed as a substitute for  disclosure  determined in
accordance  with  GAAP,  nor  are  they  necessarily   compatible  to  the  GAAP
performance  measures  presented  by our  companies.  A  reconciliation  of GAAP
results and  non-GAAP  performance  measures is provided on our  website.  Again
welcome to the  transaction -- welcome to the call on the  transaction.  I would
like to give just a few brief summary of the  transaction.  The price per common
shares is $32.50.  The aggregated  approximate deal value is approximately  $137
million and the form of  consideration  is a 100 percent TSFG common stock.  The
pricing  mechanism is that TSFG stock will be valued  based on a 10-day  trading
average immediately  following the Federal Reserve approval of not less than $21
a share  and not  greater  than  $25 per  share.  At  above  $25 a  share,  MBFC
shareholders  receive  a  fixed  exchange  ratio  of 1.3.  At  below  $21,  MBFC
shareholders  receive  a fixed  exchange  ratio of  1.548  shares.  A walk  away
provision  if the price goes above $29 or below $17 during the  average  period.
The  expected   closing  will  be  October  2003.  Other   assumptions   include
approximately  $5.1 million in cost saves in 2004 or approximately 20 percent of
MBFC's non-interest  expenses.  Merger-related  charges  approximately total $13
million from employment  contracts,  contract  termination,  professional  fees,
system  conversions,  and other costs.  The MBFC preferred  stock is going to be
converted  into TSFG common  stock.  Due  diligence  is  complete.  Our required
approvals  include  the MBFC  shareholders  and  regulatory  bodies  meaning the
Federal  Reserve and the State of North  Carolina.  This deal is priced at about
2.4 times MBFC's book.  This compares to the Southeast  Regional median of about
2.4, and it's 2.5 times their  tangible book which is again  slightly  above the
Southeastern  average of 2.3 percent. It is 20.4 times MBFC's trailing 12-months
earnings with the Southeast median of 23.2. With that I'll ask Mr. Mack Whittle,
Chief Executive  Officer of South Financial Group to continue the  presentation.
MR. MACK WHITTLE:  Thank you Bill and good morning. I want to lead out with some
comments  we've  made at some  of our  earlier  analyst  calls  and  some of our
quarterly calls and that is a little recap of what our acquisition  strategy has
been  and  what  it  continues  to be.  Our  commitment  is  that  we will do no
acquisition that is not accretive to the financial goals that we have set forth.
And I am pleased to report that this transaction is accretive both on a cash and
a GAAP EPS basis  within the first  12-months  of the  transaction.  And that we
would be equally as disciplined in the demographic footprint that we look at. We
feel that in order to enhance the value of our franchise  that we need to be the
most  attractive  markets  in  the  Southeast  and we  truly  believe  that  the
Hendersonville, Asheville, Brevard markets in North Carolina meet that test with
the attractiveness.  With that I'll talk a little bit -- the other thing that we
are  committed  to was that we would not do a  transaction  in the first half of
2003 and as Bill pointed out earlier,  this transaction is scheduled to close in
the fourth quarter. So our strategic and financial focus that we've talked about
in a number of our meetings of building consistent  quarter-to-quarter operating
EPS should be able to continue  with this  transaction,  will continue with this
transaction.  The franchise of  MountainBank  Financial  Corporation is about an
$850 million asset company.  They are  headquartered in  Hendersonville in North
Carolina.  They  began  operations  in 1997.  They  operate  18  branches  in 10
Counties.  They are the largest  community bank  headquartered  in Western North
Carolina.  Their  geographic  footprint  as I've talked  about  before  includes
Asheville  and  Hendersonville,  North  Carolina  and a  branch  soon to open in
Brevard.  These markets as you'll see in the presentation  that will be sent out
are  contiguous  to the  South  Carolina  markets.  Henderson  County  really is
contiguous  to  Greenville  County.  70 percent of these  deposits are within 50
miles of our  headquarters  office in Greenville,  South Carolina.  They have an
exceptional  customer  service culture which is in keeping with our culture.  We
think the cultures  will work very well  together and they have  impressive  net
income and balance sheet growth over the years.  As I've mentioned  earlier,  in
Henderson  County which  includes  Hendersonville,  they are the second  largest
financial  institution with over $310 million in deposits which represents about
24 percent of market share and there are a new entry into the Asheville  market.
They've got about $50 million in deposits in Asheville  and will soon be opening
in  Brevard.  Again  these are  retirement  markets  that are very much like the
markets  that we operate in along the Coast of South  Carolina  and the  Florida
markets.  Oddly  enough  as we got  into  this we  discovered  that  many of our
customers in the Florida  markets that we serve  vacation in the summer in these
markets in North Carolina,  which is very favorable to the  transaction.  One of
the  things  that we  have  done  in the  presentation  is  we've  talked  about
population growth,  we've talked about household income growth, and we've talked
about the  footprint  in the  demographics  of the  markets  that we serve.  The
population  growth,  household  growth and median household income growth in the
primary markets that  MountainBank  operates in are in keeping with those of the
other markets that we operate in. Quickly the  Hendersonville,  Henderson County
market,  its population growth projected for the next five years is 8.2 percent.
The median  weighted  South  Financial  Group is 7.7.  So it exceeds  the median
weighted of our franchise in total. The United State median population growth is
4.8 percent. So you can see it's growing.  The Hendersonville  market is growing
at about twice the rate of the United  States.  The  Buncombe  County  market is
growing at 5.3  percent  which is again in excess of the United  States  median.
Household  growth looks very  similar.  Household  income growth in the Buncombe
County,  Asheville,  North  Carolina  market is our second fastest growth market
behind Myrtle Beach at 19.6. The weighted  average of the South  Financial Group
household income growth is 18 percent. So it is over that market. It exceeds the
Tampa market. It exceeds the Jacksonville  market. It exceeds all but the Myrtle
Beach market in our  demographic  footprint.  So you can  understand  why we are
excited the way the  demographics of the transaction fit within the footprint of
The South  Financial  Group.  The other  thing  that we've  talked  about is the
financial  performance of the company and that we will do acquisitions that were
fairly  priced but would be  accretive to the  financial  goals that we have set
forth as a company.  As Bill  pointed  out  earlier  on,  the price of  trailing
earnings at 20.4 is below the median of the Southeastern transactions. The price
to book at 2.4 is slightly  above the median of the  Southeastern  transactions,
and the premium to tangible book is slightly below the Southeastern  average. So
we feel like it's a very favorably priced from our standpoint.  Due diligence is
completed as I've  mentioned  earlier.  The  transaction is expected to close in
October of this year.  Approximately  $5.1 million  pre-tax merger cost saves or
roughly 20 percent are estimated in the numbers that we are talking about today.
We've not  included any revenue  enhancements.  If you followed our company over
the last  several  quarters,  you have seen the growth that we have seen.  We've
been able to  generate a  non-interest  income as measured  by a  percentage  of
revenue. There are tremendous  opportunities in these markets and they look very
similar to our South  Carolina  and Florida  markets.  In closing I want to just
kind of highlight the transaction one more time. Again it is in very attractive,
high growth banking markets in keeping with the message that we have sent to the
market.  It is  consistent  with the strategy to operate in the most  attractive
Southeastern banking markets. Again 75 percent of the markets -- the deposits of
this franchise are within 50 miles of our headquarters.  Many of their customers
are our customers.  Many of the people who work in the  Asheville/Hendersonville
market live in Greenville and many who live in Hendersonville and Asheville work
in the  Greenville  market.  So  there's  a lot of  closeness  within  those two
markets,  although they are in different  states.  It does enhance the financial
and  strategic  goals  that we have set  forth in the  past.  As I've  mentioned
earlier,  the  growth  is  occurring  in these  markets.  A lot of it is  resort
communities.  A lot of it is the increased number of retirees that are moving to
these mountain markets.  They are typically higher income. They typically have a
greater need for non-interest  income  services.  Not unlike many of the Florida
markets  that we serve.  And with that I will turn the program  back over to the
moderator and we can open it up for questions.  THE OPERATOR: Thank you. At this
time The South  Financial  Group will address  question from  analysts.  (CALLER
INSTRUCTIONS) John Kline from Sander O'Neill.  THE CALLER: Just a quick question
from a technology  standpoint,  are there any concerns in terms in being able to
integrate  this,  Mack? MR. MACK WHITTLE:  This should be - they are on a FiServ
platform  which is the  platform  we're on. They have done that on an  outsource
basis.  We  absolutely  see no issues at all. We spent  almost  three days.  Our
technology  folks  spent  about three days up there with them and it should be a
seamless  transition.  THE CALLER:  Really  enhances  the map when I look at the
franchise.  Any  thoughts on Georgia?  MR. MACK  WHITTLE:  You know we like this
market  because  it is so close to  Greenville.  We like these  markets  because
there's a lot of resort growth or retirement growth occurring there. The markets
that are  contiguous  to South  Carolina  that are Georgia  markets don't really
offer that unless you went down to the Coastal area of Georgia. The Coastal area
of Georgia has always  intrigued  us. There are just not a lot of  opportunities
down there.  But Atlanta and some of those other interior markets within Georgia
really are not within  that  market that we call our  footprint  right now.  THE
CALLER: Okay very good. Thanks. THE OPERATOR: Thanks and the next question comes
from Gary Tenner of Sun Trust Robinson  Humphrey.  THE CALLER:  I wonder Mack if
you could talk about the asset  quality  at  MountainBank.  It looks like in the
first quarter pretty  significant  increases in charge-offs  and  non-performing
assets kind of how you guys went about when you were doing  studying  here?  MR.
MACK  WHITTLE:  Mike Sperry,  our Chief Risk  Officer,  spent about two weeks up
there.  And I might add that J.W.  Davis,  the President of this bank,  and Mike
Sperry worked  together at NCNB for a number of years when J.W.  Davis worked in
South Carolina.  We know each other very well, and we are  comfortable  with his
credit  skills.  The  increase in  charge-offs  were the result of one loan.  It
represented  $1.5 million if you normalize the  charge-offs net of that then the
charge-offs will look fairly flat. The  non-performers -- we studied quite a bit
and really we didn't see anything that was alarming in those non-performers that
created any issues with Mike or any of Mike's  people.  You know, I think from a
credit's standpoint, again we got a company with about $800 million of assets. A
lot of these  people  are  people  that J.W.  Davis and his  lenders  have known
through their banking in the Hendersonville, Asheville market. It's not unlike a
typical  financial  institution of that size where character and the individuals
play a big role in the way you underwrite  your credits.  Not unlike the way our
company  looked at this  age.  So I would say that at this size and this age the
company looks very similar to the way our company looked at five years old and a
billion dollars in assets.  THE CALLER: And one follow-up  question,  Mack. What
will J.W.'s  role be at the firm?  I know he's with the Board but is he going to
have a day-to-day role? MR. MACK WHITTLE: J.W. will be a member of our Corporate
Board.  He will be an Executive Vice President of The South  Financial Group and
will be President  of the North  Carolina  bank.  THE CALLER:  Okay,  which will
retain the name MountainBank?  MR. MACK WHITTLE: Yes. THE CALLER: Thank you. THE
OPERATOR: Todd Hagerman with Fox-Pitt, Kelton. THE CALLER: Mack, I was wondering
if you could just talk a little bit about the earnings  growth  assumptions  you
have for MountainBank in terms of your model,  your  expectations for accretion,
and when I look at some of the recent history in terms of the performance matrix
of  MountainBank,   I  noticed  that  some  of  the  profitability   matrix  can
particularly  kind of fall well short of The South  Financial  Group's  goals in
terms of profitability matrix here. I was wondering if you just reconcile,  kind
of what are your  expectations here going forward and what assumptions you build
in terms of earnings and the  integration  between the two  franchises?  MR MACK
WHITTLE:  Mary,  I'll start on that and you come in. Our model looks at about 15
percent  growth for their  company which is quite below where they have averaged
over the last five years. We've approached it on a fairly conservative basis. As
I've mentioned earlier, the assumptions on cost saves are at 20 percent. We have
historically done a little better than that but we want to make sure that we can
retain the  customer-friendly  culture that they have been able to establish and
at looking at this transaction  financially and making sure that it is accretive
to what we are  proposing  as our  goals.  We wanted to air on the  conservative
side,  but as I've mentioned  earlier both from a GAAP and a cash  standpoint on
our model and on the street estimate, it is accretive.  MS. MARY GENTRY: This is
Mary Gentry, Todd we have presentation files which are available on our website.
In  there,  in page  11,  we laid  out the pro  forma  results  that  get to the
estimated  accretion  for 2004 on both a GAAP and a cash basis.  And in there we
show the estimates for MountainBank's net income that we used as projections. So
I think that will assist you in looking at the  projections.  MR. MACK  WHITTLE:
Todd,  there's also a breakdown of the cost saves that are in that  presentation
as well.  As Mary has said they are  available -- should be available now on our
website. THE CALLER: Okay great. And perhaps maybe, Mack, could you just quickly
comment in terms of the  expected  capital  impact,  I know just from a tangible
capital  basis,  you guys have been running  somewhat thin in that respect.  But
what are your  expectations on that front?  MR. MACK WHITTLE:  You know with the
models that we run showed  relatively  neutral to the  tangible  capital.  It is
below  where we normally  like to see it, but it is neutral to that  ratio.  THE
CALLER:  Okay thank you. THE  OPERATOR:  David West of Davenport & Company.  THE
CALLER: I have two questions.  First,  given pro forma-wise you have a franchise
in Western part of North  Carolina's  Coastal area. I was wondering if you could
comment about your possible  interest in the Piedmont area of the state? And the
second question was MountainBank had a 10-day transaction with CNB of Pulaski in
Virginia.  I'm  wondering if you could  comment  about the impact of this merger
upon that pending transaction?  Thank you. MR. MACK WHITTLE:  I'll talk a little
bit about North Carolina.  Again we will be very  disciplined  about markets and
markets that we move into. And they would need to meet the  demographic  profile
that we have talked about and that the population  growth, the household growth,
and household median income growth exceed the United States and the Southeastern
average.  At least the core part of the franchise  exceeds  that.  Now there are
one-off  branches in some of the  acquisitions  we have done that we  reasonably
studied to  determine  whether  it's a market we could stay in and expand or one
that we should  exit or should  look at an exit  strategy  on. So I don't see us
looking aggressively elsewhere in North Carolina. Charlotte proper is probably a
market we would not move into.  As you know we are in York County,  which is the
South Carolina County just south of Mecklenberg County. We have great growth and
experience  in that  market  and would look to  continue  to build  around  that
peripheral  market of Charlotte and not Charlotte  proper  market,  but we'll do
that from  organic  standpoint  rather than from  acquisitions.  There are other
markets in North Carolina that exceed the demographic  profile that we've talked
about that we would be  interested  in.  Nothing  currently  on the  radar.  The
Virginia transaction, I think, today. They met with their shareholders yesterday
to  discuss  the  future  of  MountainBank  and they will go  forward  with that
transaction.   THE  CALLER:   Thank  you  very  much.   THE  OPERATOR:   (CALLER
INSTRUCTIONS)  Jeff Davis (ph) with FTN MidWest  Research (ph). THE CALLER:  Hi,
good morning. MR. MACK WHITTLE: Good morning, Jeff. THE CALLER: Actually most of
my (indiscernible) questions have been answered but a little bit of follow-up on
Mack. What type of lending does MountainBank mostly do and how does that compare
to what you all do in your  core  Greenville  (indiscernible)  market?  And then
secondly,  from a  broader  prospective,  what are you  seeing  in terms of loan
demand? You have a little bit of a pick up at the end of the quarter,  following
through [have] things softened up throughout  your footprint.  MR. MACK WHITTLE:
That's a good question.  [The]  Ashville\Hendersonville  markets look similar to
the  Greenville  South  Carolina.  Again if you drew a  circle  50 miles  around
Greenville,  South Carolina which is where we got 10 percent of our franchise in
our  headquarters  you  would  cover 75  percent  of their  business  loans  and
deposits.  Many of their customers we know. Most of their business is not unlike
what our business look like early on. They are small,  locally owned  businesses
usually first or second generation family-owned businesses that they do business
with. So predominantly, our small commercial business in those markets, although
they are beginning to grow not only their interest income, but their retail side
as well.  On the loan growth  question,  we are still seeing nice loan growth in
South  Carolina.  I think I've mentioned this in the earlier call. We introduced
the  commercial  part of our  elevate  process,  which is our Cohen  Brown sales
culture  changes to our commercial  lenders back at the end of last year. We are
at  double-digit,  strong  double  digit loan  growth in South  Carolina.  It is
basically moving business or taking share from other banks. As you know, there's
a major  acquisition  taking  place in South  Carolina  between  First Union and
Wachovia. And we are the recipient of some of that business as we hoped we would
be. We're seeing strong loan growth in South  Carolina and in the Florida market
as well,  but  especially in the South  Carolina,  both in deposits and loans. I
think we have given guidance earlier that we would have double digit loan growth
this  year.  And I can tell you that we are on a run rate to have  double  digit
loan  growth.  THE  CALLER:  Okay very good.  Thank  you,  Mack.  THE  OPERATOR:
Jefferson  Harralson  with KBW. THE CALLER:  My question is  regarding,  and you
might already answered it and I apologize I came on just a little late, how much
due diligence have you done in MountainBank and a general question,  when you do
due diligence what  percentage of the loan do you usually look at before you buy
a bank?  MR. MACK WHITTLE:  Mike and his team spent the better part of two weeks
up in MountainBank. We typically start with the -- and the way our process we do
- -- we generally do a random  sample.  And we random sample all loans of any size
in a random basis both for credit quality,  underwriting, and collateral. Making
sure  that  collateral  is back in  place.  We will  look at every  loan that is
non-performing  and that is on their  "watch" list from the same  perspective---
from   underwriting,   from  guarantor   strength,   from  collateral  and  from
documentation  standpoint.  So all of those have been  reviewed.  And we look at
general  underwriting skills and spend a paramount of time with the Chief Credit
Officer  which we have done  with  this  institution.  Again  it's not  unlike a
typically  bank of this  size  underwriting  as ---a  little  different  as ours
- ---character of the individuals and the collateral play a big role in the credit
position.  Then  there's  cash flow which again is not unlike  [most]  financial
institutions  look at this  stage.  We know  many of the  borrowers  because  we
operate in the same  markets.  So we feel  really  good about -- We feel as good
about the quality of these  credits as we do about the other  transactions  that
we've done in the past (technical  difficulty).  THE CALLER:  Okay thanks a lot.
THE OPERATOR:  Dan Hash (ph) of Millenium Partners.  THE CALLER: My question was
answered so I'm all set. Thank you. MR. MACK WHITTLE: Okay thanks. THE OPERATOR:
Thank  you.  A replay of this call will be  available  through  May 22.  You may

         FORWARD-LOOKING STATEMENTS AND NON-GAAP FINANCIAL INFORMATION


The  forward-looking  statements  being  made  today  are  subject  to risks and
uncertainties.  TSFG's actual results may differ materially from those set forth
in such  forward-looking  statements.  Reference is made to TSFG's reports filed
with the Securities and Exchange Commission for a discussion of factors that may
cause such differences to occur.

This presentation contains certain non-GAAP measures, which TSFG management uses
in our analysis of TSFG's  performance.  These  measures  typically  adjust GAAP
measures to exclude the effects of non-operating  items,  such as merger-related
costs and gains or losses on  asset  sales, and the  amortization of intangibles
for "cash basis" performance  measures.  These disclosures should not  be viewed
as a substitute for disclosure determined in accordance with GAAP,  nor are they
necessarily  comparable  to non-GAAP  performance  measures  presented  by other
companies.  A reconciliation of GAAP results and non-GAAP  performance  measures
