after the receipt by the Trustee of notice of demand or claim or the
commencement of any action, suit or proceeding, pursuant to which the Trustee
intends to seek indemnification under this paragraph, it shall notify the
Company in writing of such claim (hereinafter referred to as the "Indemnified
Claim"). The Trustee shall have the right to conduct and manage the defense
against such Indemnified Claim, provided, that the Trustee shall obtain the
consent of the Company with respect to the selection of counsel, which consent
shall not be unreasonably withheld. The Company may participate in such action
with its own counsel;

                  (c)   Pay the Trustee an initial acceptance fee of $_____ and

other fees or charges of the Trustee except as may be provided in paragraph 2(b)
hereof (it being expressly understood that the Property shall not be used to
make any payments to the Trustee under such paragraph);

                  (d)   Provide to the Trustee any letter of intent, agreement
in principle or definitive agreement that is executed in connection with a
Business Combination; and

stockholders regarding a Business Combination, provide to the Trustee an
affidavit or certificate of a firm regularly engaged in the business of
soliciting proxies and tabulating stockholder votes verifying the vote of the
Company's stockholders regarding such Business Combination.

                  (f)   Within five business days after the Representative's
over-allotment option (or any unexercised portion thereof) expires or is
exercised in full, provide the Trustee notice in writing (with a copy to the
Representative) of the total amount of the Deferred Discount, which shall in no
event be less than $1,760,000.

3.   Limitations of Liability. The Trustee shall have no responsibility or
liability to:

                  (a)   Take any action with respect to the Property, other than

party except for liability arising out of its own gross negligence or willful
misconduct;


                                       3





                  (b)   Institute any proceeding for the collection of any
principal and income arising from, or institute, appear in or defend any
proceeding of any kind with respect to, any of the Property unless and until it

so and the Company shall have advanced or guaranteed to it funds sufficient to
pay any expenses incident thereto;

                  (c)   Change the investment of any Property, other than in
compliance with paragraph 1(c);

                  (d)   Refund any depreciation in principal of any Property;

                  (e)   Assume that the authority of any person designated by
the Company to give instructions hereunder shall not be continuing unless
provided otherwise in such designation, or unless the Company shall have
delivered a written revocation of such authority to the Trustee;

                  (f)   The other parties hereto or to anyone else for any
action taken or omitted by it, or any action suffered by it to be taken or
omitted, in good faith and in the exercise of its own best judgment, except for
its gross negligence or willful misconduct. The Trustee may rely conclusively
and shall be protected in acting upon any order, notice, demand, certificate,
opinion or advice of counsel (including counsel chosen by the Trustee),
statement, instrument, report or other paper or document (not only as to its due
execution and the validity and effectiveness of its provisions, but also as to
the truth and acceptability of any information therein contained) which is
believed by the Trustee, in good faith, to be genuine and to be signed or
presented by the proper person or persons. The Trustee shall not be bound by any
notice or demand, or any waiver, modification, termination or rescission of this
Agreement or any of the terms hereof, unless evidenced by a written instrument
delivered to the Trustee signed by the proper party or parties and, if the
duties or rights of the Trustee are affected, unless it shall give its prior
written consent thereto;

                  (i)   Pay any taxes on behalf of the Trust Account except as
set forth in paragraph 1(i).

4.   Trust Fund Waiver. The Trustee has no right, title, interest, or claim of
any kind ("Claim") in or to any monies in the Trust Account, and hereby waives
any Claim in or to any monies in the Trust Account it may have in the future,
and hereby agrees not to seek recourse, reimbursement, payment or satisfaction
for any Claim against the Trust Account for any reason whatsoever.

5.   Termination. This Agreement shall terminate as follows:

                  (a)   If the Trustee gives written notice to the Company that
it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee. At such time that the Company notifies
the Trustee that a successor trustee has been appointed by the Company and has
agreed to become subject to the terms of this Agreement, the Trustee shall
transfer the management of the Trust Account to the successor trustee, including
but not limited to the transfer of copies of the reports


                                       4





and statements relating to the Trust Account, whereupon this Agreement shall
terminate; provided, however, that, in the event that the Company does not
locate a successor trustee within ninety days of receipt of the resignation
notice from the Trustee, the Trustee may submit an application to have the
Property deposited with the United States District Court for the Southern

liability whatsoever that arises due to any actions or omissions to act by any
party after such deposit; or

Termination Letter, this Agreement shall terminate except with respect to
paragraph 2(b).

6.   Miscellaneous.

                  (a)   The Company and the Trustee each acknowledge that the
Trustee will follow the security procedures set forth below with respect to
funds transferred from the Trust Account. Upon receipt of written instructions,
the Trustee will confirm such instructions with an Authorized Individual at an
Authorized Telephone Number listed on the attached Exhibit D. The Company and
the Trustee will each restrict access to confidential information relating to
such security procedures to authorized persons. Each party must notify the other
party immediately if it has reason to believe unauthorized persons may have
obtained access to such information, or of any change in its authorized
personnel. In executing funds transfers, the Trustee will rely upon account
numbers or other identifying numbers of a beneficiary, beneficiary's bank or
intermediary bank, rather than names. The Trustee shall not be liable for any
loss, liability or expense resulting from any error in an account number or
other identifying number, provided it has accurately transmitted the numbers
provided.

                  (b)   This Agreement shall be governed by and construed and
enforced in accordance with the laws of the State of New York, without giving
effect to conflict of laws. It may be executed in several counterparts, each one
of which shall constitute an original, and together shall constitute but one
instrument.

                  (c)   This Agreement contains the entire agreement and
understanding of the parties hereto with respect to the subject matter hereof.

                  (d)   This Agreement or any provision hereof may only be
amended or modified by a writing signed by each of the parties hereto, provided,
however, that no such amendment or modification (other than to correct a
typographical or similar technical error) may be made to paragraphs 1(i), 1(j),
1(k), 1(l), 2(d) and 2(e) and Exhibits A and B hereof without the consent of all
of the Public Stockholders, it being the specific intention of the parties
hereto that each Public Stockholder is and shall be a third-party beneficiary of
this paragraph 6(d) with the same right and power to enforce this paragraph 6(d)
as either of the parties hereto. For purposes of this paragraph 6(d), the
"consent of all of the Public Stockholders" shall mean receipt by the Trustee of
a certificate from an entity certifying that (i) such entity regularly engages
in the business of serving as inspector of elections for companies whose
securities are publicly traded, and (ii) either (a) 70% of the Public
Stockholders of record as of a record date established in accordance with
Section 213(a) of the Delaware General Corporation Law, as amended (the "DGCL"),
have voted in favor of such amendment or modification or (b) 70% of the Public
Stockholders of record as of a record date established in accordance with
Section 213(b) of the DGCL has delivered to such entity a signed writing
approving such amendment or modification.

                  (e)   The parties hereto consent to the jurisdiction and venue
of any state or federal court located in the City of New York for purposes of
resolving any disputes hereunder.

Continental Stock Transfer
& Trust Company

Attn: Steven G. Nelson


Re: Trust Account No.     Termination Letter


Gentlemen:

      Pursuant to paragraph 1(j) of the Investment Management Trust Agreement
between Bank Street Telecom Funding Corp. (the "Company") and Continental Stock
Transfer & Trust Company ("Trustee"), dated as of _____________, 2006 (the
"Trust Agreement"), this is to advise you that the Company has entered into an
agreement (the "Business Agreement") with ______________(the "Target Business")
to consummate a business combination with the Target Business (a "Business
Combination") on or about [insert date]. The Company shall notify you at least
two business days in advance of the actual date of the consummation of the
Business Combination (the "Consummation Date"). Capitalized terms used but not
otherwise defined herein shall have the meanings ascribed to such terms in the
Trust Agreement.

      Pursuant to paragraph 2(e) of the Trust Agreement, we are providing you
with an affidavit or certificate of _____________, which verifies the vote of
the Company's stockholders in connection with the Business Combination,
including the identities of the Public Stockholders who exercised their
conversion option in connection with the Business Combination (the "Vote
Verification"). In accordance with the terms of the Trust Agreement, we hereby
authorize you to commence liquidation of the Trust Account to the effect that,
on the Consummation Date, all of the funds held in the Trust Account will be
immediately available for disbursement.

      On the Consummation Date: (i) counsel for the Company shall deliver to you
written notification that the Business Combination has been consummated, and
(ii) the Company shall deliver to you written instructions with respect to the
transfer of the funds held in the Trust Account ("Instruction Letter"). You are
hereby directed and authorized to transfer the funds held in the Trust Account
immediately upon your receipt of the counsel's letter and the Instruction
Letter, (a) as directed in writing by the Representative, in an amount equal to
the Deferred Discount; (b) to Public Stockholders who exercised their conversion
option in connection with the Business Combination, in an amount equal to their
pro rata share of the amounts in the Trust Account as of two business days prior
to the Consummation Date (including the Deferred Discount and any income
actually received on amounts in the Trust Account but less an amount equal to
estimated taxes that are or will be due on such income at an assumed rate of
[__]% and less the amount of Net Income released to the Company pursuant to
paragraph 1(k) of the Trust Agreement); and (c) the remainder in accordance with
the terms of the Instruction Letter. In the event that certain deposits held in
the Trust Account may not be liquidated by the Consummation Date without
penalty, you will notify the Company of the same and the Company shall direct
you as to whether such funds should remain in the Trust Account and be disbursed
after the Consummation Date to the Company. Upon the disbursement of all the
funds in the Trust Account pursuant to the terms hereof, the Trust Agreement
shall be terminated and the Trust Account closed.







      In the event that the Business Combination is not consummated on the
Consummation Date described in the notice thereof and we have not notified you
on or before the original Consummation Date of a new Consummation Date, then the
funds held in the Trust Account shall be reinvested as provided in the Trust
Agreement on the business day immediately following the Consummation Date as set
