                                 August 4, 2004

Board of Directors
U.S. Helicopter Corporation

            RE:   3B GROUP, INC.
                  SUBSCRIPTION FOR COMMON STOCK

Dear Sirs:

      1. The undersigned (the "Purchaser") hereby offers to subscribe to SEVEN
HUNDRED FIFTY THOUSAND (750,000) shares (the "Shares") of Common Stock, par
value $.001 per share, of U.S. Helicopter Corporation, a Delaware corporation
(the "Company"), in consideration of Purchaser's efforts to assist the Company
to raise capital and to induce Cornell Capital Partners, LP to make a
contemporaneous investment in the Company. It is understood that the Company
will deliver to the Purchaser a certificate for the Shares in consideration of
the foregoing.

      2. The Purchaser hereby represents and warrants to the Company that the
Purchaser is acquiring the Shares for its own account for investment and not
with a view to the distribution thereof or with any present intention of selling
any thereof. The Purchaser acknowledges that it has been informed by the Company
that the Shares have not been registered under the Securities Act of 1933, as
amended (the "Securities Act") and that the Shares must be held indefinitely
unless subsequently registered under the Securities Act or an exemption from
such registration is available. The Purchaser also acknowledges that it is fully
aware of the restrictions on disposing of the Shares resulting from the
provisions of the Securities Act and the General Rules and Regulations of the
Securities and Exchange Commission thereunder (including, without limitation,
Rule 144). The Purchaser understands that under the present circumstances sales
of the Shares may not be made in reliance upon Rule 144 since, among other
reasons, the requisite information concerning the Company is not publicly
available, and that the Company is under no obligation to the Purchaser to
supply to the Purchaser or disclose to the public the information necessary to
enable the Purchaser to make sales under Rule 144. The Purchaser further
understands that the Company is under no obligation to register the Shares
(except as provided in Section 3) or to effect compliance with Regulation A or
any other exemption.

      3. Prior to any sale, transfer, pledge or other disposition of any of the
Shares, the holder of such Shares shall give written notice to the Company of
such proposed sale, transfer, pledge or other disposition and as to the
circumstances thereof. Promptly upon receiving such notice, the Company shall
obtain from the Company's counsel and, if the Company at its option so requests,
the holder will obtain from his counsel and deliver to the Company, as promptly
as practicable, an opinion as to whether the proposed sale, transfer, pledge or
disposition may be effected without registration of such Shares under the
Securities Act. If in the opinion of each such counsel such sale, transfer,
pledge or disposition may be made in the manner described in the notice thereof,
the holder may

<PAGE>

make such sale, transfer, pledge or disposition. If either counsel shall fail to
render an opinion to such effect, the holder shall not make such sale, transfer,
pledge or disposition unless and until registration of such Shares under the
Securities Act has become effective or is no longer required in the opinion of
the respective counsel.

      4. The Purchaser agrees not to sell any of the Shares during the six-month
period commencing on the effective date of the Company's first registration
statement declared effective under the Securities Act by the SEC. The Purchaser
acknowledges and agrees that the Shares will be marked with a customary
Securities Act legend.

                                           Very truly yours,

                                           3B Group, Inc.
