covering a proposed public offering of its securities as described on the Information Sheet;

 

WHEREAS, the Underwriter proposes to offer the Securities,
as agent for the Issuer, for sale to the public on a “best efforts” only basis for at least the Minimum Securities

WHEREAS the Issuer and the Underwriter propose to establish
an Escrow Account (the “Escrow Account”), to which subscription monies which are received by the Escrow Agent
from the Underwriter in connection with such public offering are to be credited, and the Escrow Agent is willing to establish the
Escrow Account and the terms are subject to the conditions hereinafter set forth;

 

WHEREAS, the Escrow Agent has an agreement with JP Morgan
Chase (the “Bank”) to establish a special Bank Account (defined below) into which the subscription monies, which
are received by the Escrow Agent from the Underwriter and credited to the Escrow Account, are to be deposited; and

 

NOW, THEREFORE in consideration of the premises and mutual
covenants herein contained, the parties hereto hereby agree as follows:

 

		1	Information
Sheet. Each capitalized term not otherwise defined in this Agreement shall have the meaning set forth for such
term on the information sheet which is attached to this Agreement and is incorporated by reference herein and made a part hereof
(the “Information Sheet”).

 

		2	Establishment
of the Bank Account.

 

		2.1	The
Escrow Agent shall establish a non-interest bearing bank account at a branch of JP Morgan Chase selected by the Escrow Agent,
and bearing the designation set forth on the Information Sheet (heretofore defined as the “Bank Account”).
The purpose of the Bank Account is for (a) the deposit of all subscription monies (checks, or wire transfers) which are received
by the Underwriter from prospective purchasers of the Securities and are delivered by the Underwriter to the Escrow Agent, (b)
the holding of amounts of subscription monies which are collected through the banking system, and (c) the disbursement of collected
funds, all as described herein.

  

     

     

    

  

		2.2	On
or before the date of the initial deposit in the Bank Account pursuant to this Agreement, the Underwriter shall notify the Escrow
Agent in writing of the effective date of the Registration Statement (the “Effective Date”), and the Escrow
Agent shall not be required to accept any amounts for credit to the Escrow Account or for deposit in the Bank Account prior to
its receipt of such notification.

 

		2.3	The
offering period, which shall be deemed to commence on the Effective Date, shall consist of the number of calendar days or business
days set forth on the Information Sheet (the “Offering Period”). The Offering Period shall be extended by an
Extension Period (as defined in the Information Sheet) only if the Escrow Agent shall have received joint written notice thereof
from the Issuer and the Underwriter at least five (5) business days prior to the expiration of the Offering Period. The Extension
Period, which shall be deemed to commence on the next calendar day following the expiration of the Offering Period, shall consist
of the number of calendar days or business days set forth on the Information Sheet. The last day of the Offering Period, or the
last day of the Extension Period (if the Escrow Agent has received written notice thereof as hereinabove provided), is referred
to herein as the “Termination Date”. Except as provided in Section 4.3 hereof, after the Termination Date the
Underwriter shall not deposit, and the Escrow Agent shall not accept, any additional amounts representing payments by prospective
purchasers.

to the Bank Account.

 

		3.1	The
Underwriter shall promptly deliver to the Escrow Agent all monies in the form of checks or wire transfers which it receives from
prospective purchasers of the Securities by noon of the next business day following receipt where internal supervisory review
is conducted at the same location at which subscription documents and monies are received.  Upon the Escrow Agent’s
receipt of such monies, they shall be credited to the Escrow Account. All checks delivered to the Escrow Agent shall be made payable
to “      ”Any check payable other than to the Escrow Agent as required hereby shall
be returned to the prospective purchaser, or if the Escrow Agent has insufficient information to do so, then to the Underwriter
(together with any Subscription Information, as defined below, or other documents delivered therewith) by noon of the next business
day following receipt of such check by the Escrow Agent, and such check shall be deemed not to have been delivered to the Escrow
Agent pursuant to the terms of this Agreement.

 

		3.2	Promptly
after receiving subscription monies as described in Section 3.1, the Escrow Agent shall deposit the same into the Bank Account.  Amounts
of monies so deposited are hereinafter referred to as “Escrow Amounts”.  The Escrow Agent shall cause
the Bank to process all Escrow Amounts for collection through the banking system.  Simultaneously with each deposit
to the Escrow Account, the Underwriter (or the Issuer, if such deposit is made by the Issuer) shall inform the Escrow Agent in
writing of the name, address, and the tax identification number of the purchaser, the amount of Securities subscribed for by such
purchase, and the aggregate dollar amount of such subscription (collectively, the “Subscription Information”).

		3.3	The
Escrow Agent shall not be required to accept for credit to the Escrow Account or for deposit into the Bank Account checks which
are not accompanied by the appropriate Subscription Information, which at minimum shall include the name address, tax identification
number and the number of shares/units.  Wire transfers representing payments by prospective purchasers shall not be
deemed deposited in the Escrow Account until the Escrow Agent has received in writing the Subscription Information required with
respect to such payments.

Escrow Agent shall not be required to accept in the Escrow Account any amounts representing payments by prospective purchasers,
whether by check or wire, except during the Escrow Agent’s regular business hours.

to Section 4.3 below, if by the close of regular banking hours on the Termination Date the Escrow Agent determines that the amount
in the Fund is less than the Minimum Dollar Amount or the Minimum Securities Amount, as indicated by the Subscription information
submitted to the Escrow Agent, then in either such case, the Escrow Agent shall promptly refund to each prospective purchaser
the amount of payment received from such purchaser which is then held in the Fund or which thereafter clears the banking system,
without interest thereon or deduction therefrom, by drawing checks on the Bank Account for the amounts of such payments and transmitting
them to the purchasers. In such event, the Escrow Agent shall promptly notify the Issuer and the Underwriter of its distribution
of the Fund.

 

		4.2	Subject
to Section 4.3 below, if at any time up to the close of regular banking hours on the Termination Date, the Escrow Agent determines

and of the amounts, constituting the Fund, which have cleared the banking system and have been collected by the Escrow Agent.

 

		5.2	The
Escrow Agent shall not be responsible for or be required to enforce any of the terms or conditions of the underwriting agreement
or any other agreement between the Underwriter and the Issuer nor shall the Escrow Agent be responsible for the performance by
the Underwriter or the Issuer of their respective obligations under this Agreement.

purchasers unless such Subscription Information is accompanied by checks, or wire transfers meeting the requirements of Section

therewith. Such amount need not be accepted for deposit in the Escrow Account until such discrepancy has been resolved.

		 	 

		5.4	The
Escrow Agent shall be under no duty or responsibility to enforce collection of any check delivered to it hereunder. The Escrow
Agent, within a reasonable time, shall return to the Underwriter any check received which is dishonored, together with the Subscription
Information, if any, which accompanied such check.

 

		5.5	The
Escrow Agent shall be entitled to rely upon the accuracy, act in reliance upon the contents, and assume the genuineness of any
notice, instruction, certificate, signature, instrument or other document which is given to the Escrow Agent pursuant to
this Agreement without the necessity of the Escrow Agent verifying the truth or accuracy thereof. The Escrow Agent shall not be
obligated to make any inquiry as to the authority, capacity, existence or identity or any person purporting to give any such notice
or instructions or to execute any such certificate, instrument or other document.

the Escrow Agent is uncertain as to its duties or rights hereunder or shall receive instructions with respect to the Bank Account,
the Escrow Amounts or the Fund which, in its sole determination, are in conflict either with other, instructions received by it
or with any provision of this Agreement, it shall be entitled to hold the Escrow Amounts, the Fund, or a portion thereof, in the
Bank Account pending the resolution of such uncertainty to the Escrow Agent’s sole satisfaction, by final judgment of a
court or courts of competent jurisdiction or otherwise;  or the Escrow Agent, at its sole option, may deposit the Fund
(and any other Escrow Amounts that thereafter become part of the Fund) with the Clerk of a court of competent jurisdiction in
a proceeding to which all parties in interest are joined. Upon the deposit by the Escrow Agent of the Fund with the Clerk of any
court, the Escrow Agent shall be relieved of all further obligations and released from all liability hereunder.

  

    4

     

    

  

		5.7	The
Escrow Agent shall not be liable for any action taken or omitted hereunder, or for the misconduct of any employee, agent or attorney
appointed by it, except in the case of willful misconduct or gross negligence. The Escrow Agent shall be entitled to consult with
counsel of its own choosing and shall not be Liable for any action taken, suffered or omitted by it in accordance with the advice
of such counsel.

 

		5.8	The
Escrow Agent shall have no responsibility at any time to ascertain whether or not any security interest exists in the Escrow Amounts,

the banking system and the Fund for a period of not more than five (5) business days following the effective date of such resignation,
at which time (a) if a successor escrow agent shall have been appointed and written notice thereof (including the name and address
of such successor escrow agent) shall have been given to the resigning Escrow Agent by the Issuer, the Underwriter and such successor
escrow agent, then the resigning Escrow Agent shall pay over to the successor escrow agent the Fund, less any portion thereof
previously paid out in accordance with this Agreement; or (b) if the resigning Escrow Agent shall not have received written notice
signed by the Issuer, the Underwriter and a successor escrow agent, then the resigning Escrow Agent shall promptly refund the
amount in the Fund to each prospective purchaser without interest thereon or deduction therefrom, and the resigning Escrow Agent
shall promptly notify the Issuer and the Underwriter in writing of its liquidation and distribution of the Fund; whereupon, in
either case, the Escrow Agent shall be relieved of all further obligations and released from all liability under this Agreement.
Without limiting the provisions of Section 8 hereof, the resigning Escrow Agent shall be entitled to be reimbursed by the Issuer
and the Underwriter for any actual expenses incurred in connection with its resignation, transfer of the Fund to a successor escrow
agent or distribution of the Fund pursuant to this Section 6.
