Forward Looking Information

This presentation may contain certain forward-looking statements, which are based on management's

expectations regarding factors that may impact the company's earnings and performance in future periods.

Words and phrases such as: "will," "will likely result," "expect," "will continue," "anticipate, " "estimate,"

"project," "believe," "intend," "should," "would, " "may," "can," "could," "plan," "target" and similar

expressions are intended to identify "forward-looking statements." Actual results or performance could differ

from those implied or contemplated by such statements. Factors that could cause future results and

performance to differ materially from current management expectations include, but are not limited to, general

business and economic conditions, either nationally or regionally; fiscal or monetary policies; significant weather

events such as hurricanes; changes or fluctuations in the interest rate environment; continued deterioration in

credit quality and/or a reduced demand for credit; reduced deposit flows and loan demand; real estate values;

competition from other financial service companies in our markets; legislative or regulatory changes, including,

among others, changes in accounting standards, guidelines and policies; the issuance or redemption of additional

Company debt or equity; the concentration of operations in Florida, if Florida business or economic conditions

continue to decline; reliance on other companies for products and services; the impact of war and the threat and

impact of terrorism; volatility in the market price of the Company’s common stock; the company’s inability to

raise capital due to challenging market conditions; and other economic, competitive, servicing capacity,

governmental, regulatory and technological factors affecting the

Company’s operations, price, products and

delivery of services. Please refer to the documents that we file periodically with the

SEC, such as the Form 10-K

for the 2007 fiscal year, and reports on Form 10-Q for the December 31, 2007 and March 31, 2008 periods,

which contain additional important factors that could cause actual results to differ from the Company’s current

expectations and from the forward-looking statements contained in this press release

Residential Portfolio Credit Standards

No subprime lending

No piggyback loans

No

correspondent

lending

Regionally based

BankUnited underwriters knowledgeable of their

markets

Loans

underwritten

at

the

fully

indexed

rate

Loans originated with an loan-to-value (LTV) over 80% almost always

insured by private mortgage insurance

Note:

1

“Piggyback”

loans are generally second mortgage or home equity loans made by a lender to a borrower at the same time that

the lender makes the first mortgage loan.  BankUnited does not make such loans.  Piggyback mortgages are frequently used in

the mortgage industry to lower the loan-to-value ratio (LTV) of a first position mortgage to under 80%, thereby eliminating

the need for private mortgage insurance (PMI)

2

“Correspondent lending”

refers to loans originated and funded by a third party and acquired for portfolio purposes.  We do

not have any correspondent originated loans in our portfolio

3

BankUnited’s

loans were underwritten using the index rate in effect plus a margin at the time of origination, which could be

less than the maximum rate to which a loan can reset over the life of the loan

Credit Verification Process

As part of its strong credit focus, when underwriting loans based on stated

income or stated assets, BankUnited has sought to cross verify borrower

assertions through multiple channels

To validate the Company’s underwriting standards, management

conducted

a

random

sample

of

300

SISA

(Stated

Income,

Stated

Asset)

and

SIVA

(Stated

Income,

Verified

Asset)

loans

100% of sampled loans were verified for either verbal verification of

employment and reasonableness of stated income or stated assets for

the ability to make the fully indexed payment at the time of

origination.  This included examining the borrower's depth of credit,

verifying reserves and reviewing of assets, and/or confirmation of at

least two bank deposits supporting stated income

Note:

1

Sample

was

selected

by

choosing

every

sixty-fourth

loan

in

a

population

of 19,246 loans

outstanding

at

March 31,

2008.

Credit Verification Process (cont’d)

assertions at the time of origination in at least two or more monthly

deposit slips or bank statements

Based on

a

outstanding loans) :

45.3% of loans made at least 1 payment above the minimum

30.2% of loans made at least 2 payments above the minimum

24.1% of loans made at least 3 payments above the minimum
