    The

    3.           Representations
and Warranties of the Investor

    

    In order to induce the Company to
accept this Agreement, the Investor hereby represents and warrants to the
Company as follows:

    

    a.           THE INVESTOR HAS READ CAREFULLY AND
UNDERSTANDS THIS AGREEMENT AND HAS CONSULTED THE INVESTOR'S OWN ATTORNEY,
ACCOUNTANT OR INVESTMENT ADVISER WITH RESPECT TO THE INVESTMENT CONTEMPLATED
HEREBY AND ITS SUITABILITY FOR THE INVESTOR.  THE INVESTOR HAS HAD AN
OPPORTUNITY TO ASK QUESTIONS OF AND RECEIVED ANSWERS FROM THE COMPANY, OR A
PERSON OR PERSONS ACTING ON THE COMPANY'S BEHALF, CONCERNING THE TERMS AND
CONDITIONS OF THIS INVESTMENT AND THE BUSINESS OF THE COMPANY, AND HAS RECEIVED
AND REVIEWED ALL ADDITIONAL DOCUMENTATION REGARDING THE BUSINESS AND OPERATIONS
OF THE COMPANY THAT HE OR SHE HAS REASONABLY REQUESTED.

    

    b.           The
Investor (i) has no need for liquidity in the investment in the Shares, (ii) is
able to bear the substantial economic risks of an investment in the Shares for
an indefinite period, and (iii) at the present time, could afford the complete
loss of such investment in the Shares.

    

    
      
        
        

      

      
        1

        
          

        

      

      
        
        

      

    

     

    c.           The
address set forth at the end of this Agreement is the Investor's true and
correct residence, and the Investor has no present intention of changing such
residence to any other state or jurisdiction.

    

    d.           The
Investor confirms that all documents, records and books pertaining to the
investment in the Company reasonably requested by the Investor have been made
available to the Investor. The undersigned has relied only on such documents and
that no written or oral representation or information inconsistent with such
information has been made or furnished to the Investor in connection with the
Shares and if so made, has not been relied upon.

    

    e.           The
Investor understands that the Shares have not been registered under the
Securities Act, nor pursuant to the provisions of the securities laws or other
laws of any other applicable jurisdictions, in reliance on exemptions for
private offerings contained in the Securities Act and in the laws of such
jurisdictions. The Investor represents to the Company that he is an “accredited
investor”, as such term is defined in Rule 501(a) of Regulation D under the
Securities Act of 1933, as amended. The Investor is fully aware that the Shares
to which he or she is subscribing are to be sold in reliance upon such
exemptions based upon his or her representations, warranties and agreements set
forth in this Agreement. The Investor is fully aware that he or she must bear
the economic risk of his or her investment in the Company for an indefinite
period of time because the Shares have not been registered under the Securities
Act, and, therefore, cannot be offered or sold unless they are subsequently
registered under the Securities Act or an exemption from such registration is
available. The Investor further understands that the Company has no intention
and is under no obligation to register its Shares under the Securities Act or to
comply with the requirements for any exemption that might otherwise be
available, or to supply the Investor with any information necessary to enable
the Investor to make routine sales of the Shares under Rule 144 under the Securities Act
(which it understands is not now, and will not likely be, available) or any rule
of the Securities and Exchange Commission or any successor thereto.

    

    f.           The
Investor understands that the certificate(s) representing the Shares will bear
the following legend restricting its transfer and that a notation restricting
such transfer will be made on the stock transfer books of the
Company:

    

    “THE
SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE APPLICABLE
SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. THESE SHARES HAVE BEEN
ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO THEIR DISTRIBUTION OR
RESALE.  SUCH SHARES MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED
WITHOUT AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SHARES UNDER THE ACT, OR AN
OPINION OF COUNSEL SATISFACTORY IN FORM AND SUBSTANCE TO THE COMPANY TO THE
EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED.”

    

    g.           The
Shares are being acquired solely for the Investor's own account, for investment
and are not being purchased with a view to or for the resale or other
distribution of the Shares; and the Investor has no present plans to enter into
any contract, undertaking, agreement or arrangement relating to any resale or
other distribution of the Shares.

    

    h.           The
Investor understands that this Subscription may be accepted or rejected in whole
or in part in the sole and absolute discretion of the Company, and this
Agreement, unless properly revoked before the completion of the sale of the
Shares to the Investor, shall survive the Investor’s death, disability or
insolvency, except that the Investor shall have no obligations in the event that
this Subscription is rejected by the Company.

    

    i.           The
Investor understands that even if the Company becomes a "reporting company"
under the Securities Exchange Act of 1934, as amended, the provisions of Rule
144 promulgated under the Securities Act permitting resales of the Shares will
not be available for at least one (1) year, and there can be no assurance that
the conditions necessary to permit routine sales of the Shares under Rule 144
will ever be satisfied, and, if Rule 144 should become available, routine sales
made in reliance on its provisions could be made only in limited amounts and in
accordance with the terms and conditions of the Rule.  The Investor
further understands that in connection with sales of securities for which Rule
144 is not available, compliance with some other exemption from registration
will be required.  The Investor understands that the Company is under
no obligation to the undersigned to register the Shares or to comply with the
conditions of Rule 144 or take any other action necessary in order to make
available any exemption for the sale of the Shares without
registration.

    

    j.           The
Investor has been advised to consult with the Investor’s own attorney regarding
legal, tax, and other matters concerning an investment in the Company and has
done so, to the extent the undersigned considers necessary.

    

    k.           The
Investor acknowledges and is aware of the following:

    

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    (i)           that
the Shares are a speculative investment and involve a high degree of risk of
loss by the Investor of the Investor's entire investment in the
Company;

    

    (ii)          that
there is no guarantee that the Investor will realize any gain from his or her
investment in the Company and that the Investor may lose his or her entire
investment;

    

    (iii)         that
the Company has no
current plan or intention to issue dividends with respect to the
Shares;

    

    (iv)         that
there has never been any representation, guarantee or warranty made to the
Investor by any broker, the Company, its agents or employees or any other
person, expressly or by implication, as to:

    

    (A)           the
approximate or exact length of time that the Investor will be required to remain
as owner of the Shares; or

    

    (B)           the
past performance or experience on the part of the officers or directors of the
Company, or of any other person, that will in any way indicate the predictable
results of the ownership of the Shares or any such other securities, or of the
overall business of the Company;

    

    v)           that
the Company may in the future issue additional shares of capital stock in the
Company, and that the Investor's interest in the Company may thereby become
diluted.

    

    The Investor acknowledges that he or
she understands the meaning and legal consequences of the representations,
warranties and acknowledgments contained in this Agreement. The Investor
confirms that such representations, warranties and acknowledgments are true and
accurate as of the date of this Agreement and shall be true and accurate as of
the date of delivery of the Funds to the Company and shall survive such
delivery. If in any respect such representations and warranties shall not be
true and accurate prior to acceptance of this Agreement pursuant to Section 2 of
this Agreement, the Investor shall give written notice of such fact to the
Company, specifying which representations and warranties are not true and
accurate and the reasons therefor.

    

    4.           Indemnification. The Investor acknowledges
that he or she understands the meaning and legal consequences of the
representations and warranties contained in Section 3 of this Agreement, and the
Investor agrees to
indemnify, defend and hold harmless the Company and each officer, director,
representative and agent of the Company and any person or entity controlling the
Company from and against any and all loss, cost, damage or liability (including
reasonable attorneys' fees) due to or arising out of a breach of any
representation or warranty of the Investor contained in this
Agreement.

    

    5.           No
Waiver.
Notwithstanding any of the representations, warranties, acknowledgments or
agreements made in this Agreement by the Investor, the
Investor does not thereby or in any other manner waive any rights granted to the
Investor under federal and state securities law.

    

    6.           Transferability. The Investor agrees not to
transfer or assign this Agreement, or any of the Investor's interest in this
Agreement, and further agrees that any assignment or transfer of the Shares
shall be made only in accordance with applicable securities laws and that an
appropriate legend with respect thereto may be placed by the Company on any
certificate evidencing such Shares.

    

    7.           Revocation. The Investor agrees that he
or she shall not cancel, terminate or revoke this Agreement.

    

    8.           Termination
of Agreement. If
any representation or warranty of the Investor contained in Section 3 of this
Agreement shall not be true prior to acceptance of this Agreement, and written
notice of such fact has been given by the Investor to the Company, then and in
any such event this Agreement shall be null and void and of no further force and
effect, and no party shall have any rights against any other party under this
Agreement or otherwise, and the Company shall promptly return to the Investor
the Funds together with all agreements executed by the Investor.

    

    9.           Dispute
Resolution

    

    a.           All
disputes, claims, or controversies arising out of or relating to this Agreement
or any other agreement executed and delivered pursuant to this Agreement or the
negotiation, validity or performance hereof and thereof or the transactions
contemplated hereby and thereby that are not resolved by mutual agreement shall
be resolved solely and exclusively by binding arbitration to be conducted before
the American Arbitration Association (“AAA”).  If AAA ceases
operation, then the parties shall select a comparable organization that provides
qualified arbitration services.  The arbitration shall be held in
Boston, Massachusetts before a single arbitrator and shall be conducted in
accordance with the rules and regulations promulgated by AAA unless specifically
modified herein.

    

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    b.           The
parties covenant and agree that the arbitration hearing shall commence within
ninety (90) days of the date on which a written demand for arbitration is filed
by any party hereto.  In connection with the arbitration proceeding,
the arbitrator shall have the power to order the production of documents by each
party and any third-party witnesses.  In addition, each party may take
up to three depositions as of right, and the arbitrator may in his or her
discretion allow additional depositions upon good cause shown by the moving
party.  However, the arbitrator shall not have the power to order the
answering of interrogatories or the response to requests for
admission.  In connection with any arbitration, each party shall
provide to the other, no later than seven (7) business days before the date of
the arbitration hearing, the identity of all persons that may testify at the
arbitration and a copy of all documents that may be introduced at the
arbitration hearing or considered or used by a party’s witness or expert. The
arbitrator’s decision and award shall be made and delivered within three (3)
months of the selection of the arbitrator. The arbitrator’s decision shall set
forth a reasoned basis for any finding of liability or award of
damages.  The arbitrator shall not have power to award damages in
excess of actual compensatory damages and shall not multiply actual damages or
award punitive damages or any other damages that are specifically excluded under
this Agreement, and each party hereby irrevocably waives any claim to such
damages.

    

    c.           The
parties covenant and agree that they will participate in the arbitration in good
faith and that they will share equally its costs, except as otherwise provided
herein.  The arbitrator may in his or her discretion assess costs and
expenses (including the reasonable legal fees and expenses of the prevailing
party whether claimant or respondent) against any party to a
proceeding.  Any party failing or refusing to comply with an order of
the arbitrators shall be liable for costs and expenses, including attorneys’
fees, incurred by the other party in enforcing the award. Nothing in this
Section 9 shall prohibit any party from proceeding in court without prior
arbitration for the limited purpose of seeking a temporary or permanent
injunction to avoid immediate and irreparable harm.  The provisions of
this Section 9 shall be enforceable in any court of competent
jurisdiction.

    

    d.           Unless
otherwise ordered, the parties shall bear their own attorneys’ fees, costs and
expenses in connection with the arbitration.  The parties will share
equally in the fees and expenses charged by AAA.

    

    e.           Each
of the parties hereto irrevocably and unconditionally consents to the exclusive
use of AAA to resolve all disputes, claims or controversies arising out of or
relating to this Agreement or any other agreement executed and delivered
pursuant to this Agreement or the negotiation, validity or performance hereof
and thereof or the transactions contemplated hereby and thereby and further
consents to the jurisdiction of the federal or state courts of the Commonwealth
of Massachusetts for the purposes of enforcing the arbitration provisions of
Section 9a of this Agreement.  Each party further irrevocably waives
any objection to proceeding before AAA based upon lack of personal jurisdiction
or to the laying of venue and further irrevocably and unconditionally waives and
agrees not to make a claim in any court that arbitration before AAA has been
brought in an inconvenient forum.  Each of the parties hereto hereby
consents to service of process by registered mail at the address to which
notices are to be given.  Each of the parties hereto agrees that its
or his submission to jurisdiction and its or his consent to service of process
by mail is made for the express benefit of the other parties
hereto.

    

    10.           Miscellaneous

    

    a.           All
notices or other communications given or made under this Agreement shall be in
writing and shall be delivered or mailed by (a) registered or certified mail,
return receipt requested, postage prepaid, or (b) overnight air courier, fees
prepaid, to the Investor at his or her address set forth below and to the
Company at its address set forth at the outset of this Agreement.

    

    b.           Failure
of the Company to exercise any right or remedy under this Agreement or any other
agreement between the Company and the Investor, or delay by the Company in
exercising the same, will not operate as a waiver of such right or
remedy.  No waiver by the Company will be effective unless and until
it is in writing and signed on behalf of the Company.

    

    c.           Notwithstanding
the place where this Agreement may be executed by any of the parties hereto, all
