NOTICE





Any
sale in Florida made pursuant to Florida Statute § 517.061 pertaining to
transactions exempt from registration is voidable by the purchaser in such sale
within three (3) days after the first tender of consideration is made by such
purchaser to the issuer, an agent of the issuer, or an escrow
agent.





Ladies
and Gentlemen:





You have
informed the undersigned (the “Purchaser”) that BISCAYNE ACQUISITION GROUP, INC,
a Florida corporation that has no assets and no business other than to seek a
merger with a private operating business (the “Company” or “you”), wishes to
raise a maximum of Thirty Thousand Dollars ($30,000) to pay for administrative,
accounting, and legal expenses from various accredited investors by selling the
Company’s Common Stock, $0.001 par value (the “Shares”), at a price of Two and
One-Half Cents ($0.025) per Share.





I
understand that you will rely on the following information to confirm that I am
an “Accredited Investor”, as defined in Regulation D promulgated under the
Securities Act of 1933, as amended (the “Securities Act”), and that I am
qualified to be a Purchaser.





In
connection with and as consideration for the receipt of ____________ Shares for
a total price of $______________ by the undersigned Purchaser, the Purchaser
hereby represents, warrants, covenants and agrees as set forth
below.





1.           Purchase
Entirely for Own Account. The Shares are being acquired for investment purposes
only, for the Purchaser's own account, not as a nominee or agent, and not with a
view to the resale or distribution of any part thereof, and the Purchaser has no
present intention of selling, granting any participation in, or otherwise
distributing the Shares or any portion thereof. Further, the Purchaser does not
have any contract, undertaking, agreement or arrangement with any person to
sell, transfer or grant participations to such person or to any third person,
with respect to all or any portion of the Shares.





2.           No
Securities Act Registration. The Purchaser understands that the Shares have not
been registered under the Securities Act by reason of a specific exemption or
specific exemptions from the registration provisions of the Securities Act which
depend upon, among other things, the bona fide nature of the Purchaser's
investment intent as expressed herein.

3.           Restricted
Securities. The Purchaser acknowledges that, because the Shares have been issued
to a founder of, or early investor in, a shell company or blank check company,
the Shares must be held by the Purchaser indefinitely unless subsequently
registered under the Securities Act, or unless the federal securities laws are
amended to reduce applicable holding periods and/or to eliminate founder
securities resale restrictions.  Therefore, the provision of Rule 144
promulgated under the Securities Act that permits the limited resale of shares
purchased in a private placement subject to the satisfaction of certain
conditions is not available for the resale of the Shares under current
law.





4.           No
Market for Shares.  The Purchaser is fully aware that there is no
public market where the Shares may be resold, that the Shares are illiquid, and
that the Purchaser must hold the Shares indefinitely.





5.           No
Representations by the Company.  The Purchaser represents to the
Company that the Company has not made any representations or promises, material
or otherwise, concerning the Company, its business model, the target of any
proposed acquisition, the Company’s prospects for a merger, its financial
condition, or the backgrounds of any individual involved in the Company or in
selling the Shares, as an inducement to purchase the Shares.





6.           Information.  The
Purchaser is aware that all information about the Company is either set forth in
this Investment Letter or in the Company’s Form 10-SB, as amended, filed by the
Company with the U.S. Securities & Exchange Commission (“SEC”) at
www.sec.gov (by following the link to “Filing and Forms (EDGAR),” then “Search
for Company Filings”, then “Companies & Other Filers” and then entering the
words “Biscayne Acquisition Group”), and in other disclosure documents filed by
the Company with the SEC from time to time.





7.           Accredited
and Sophisticated Investor. The Purchaser represents and warrants that: (a)
either alone or with the Purchaser's professional advisor or advisors, he or she
has such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of acquiring the Shares, (c) is able
to bear the economic risk of the investment in the Shares, including a complete
loss of the investment, and (c) (a) is an accredited investor as defined in Rule
501(a) of Regulation D of the Securities and Exchange Commission; and, because
