this Agreement, which conditions are intended to ensure compliance with the
provisions of the Securities Act. Each Holder will cause any proposed purchaser,
assignee, transferee, or pledgee of the Registrable Securities held by a Holder
to agree to take and hold such securities subject to the provisions and upon the
conditions specified in this Agreement.

    

    3.     
      Restrictive

shall (unless otherwise permitted by the provisions of Section 4 below) be

        - 3 -

        
          

        

      

      
         

      

    

    

    a.           There
is in effect a Registration Statement under the Securities Act covering such
proposed disposition and such disposition is made in accordance with such
Registration Statement; or

    

    b.           Such
Holder shall have notified the Company of the proposed disposition and shall
have furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition, and if reasonably requested by the
Company, such Holder shall furnish the Company with an opinion of counsel,
reasonably satisfactory to the Company that such disposition shall not require
registration of such shares under the Securities Act.  It is agreed,
however, that no such opinion will be required for Rule 144 or Rule 144A
transactions, except as required by the Company’s transfer agent or in unusual
circumstances.

    

    c.           Notwithstanding
the provisions of paragraphs (a) and (b) above, no such Registration Statement
or opinion of counsel shall be necessary for a transfer by a Holder which is a
partnership to a partner of such partnership or a retired partner of such
partnership who retires after the date hereof, or to the estate of any such
partner or retired partner or the transfer by gift, will, or intestate
succession of any partner to his spouse or siblings, lineal descendants or
ancestors of such partner or spouse, provided, however, that such transferee
agrees in writing to be subject to all of the terms hereof to the same extent as
if he were an original Holder hereunder.

    

    5.    
       Resale
Registration Statement.

    

    Not later than thirty (30) days after
the completion of the Trestle Reverse Split, the Company shall file with the SEC
a Registration Statement (the “Resale Registration
Statement”) registering for resale at prevailing market prices all of the
Registrable Securities.  The Company shall use its best efforts to
obtain effectiveness of the Registration Statement with respect to all
Registrable Securities no later than one hundred and fifty (150) days after the
completion of the Trestle Reverse Split, and shall respond to all oral and
written comments from the staff of the SEC.

    

    a.           The
parties shall endeavor to take all actions reasonably required to obtain
effectiveness of such Resale Registration Statement or, if and to the extent
such rule becomes available, utilize the re-sale exemptions provided under Rule
144 in order to provide liquidity for these shares.

    

    b.           In
the event that the Company shall for any reason fail to:

    

    (i)           file
with the SEC the initial Resale Registration Statement within thirty (30) days
after the date of the Series A Preferred Stock Issuance (the “Required Filing Date”);
or

    
      
         

      

      
        - 4 -

        
          

        

      

      
         

      

    

    (ii)           cause
such Resale Registration Statement to be declared effective by the SEC within
one hundred and fifty (150) days after the completion of the Offering (the
“Required Effective
Date”), then and in either such event, the Company shall pay to the
Investors a cash amount that shall be equal to two percent (2%) of the aggregate
principal amount of the Notes or aggregate Stated Value of the Series A
Preferred Stock (as applicable) for each month (or part thereof) following the
Required Filing Date that the Resale Registration Statement shall not have been
duly filed with the SEC, and/or for each month (or part thereof) following the
Required Effective Date that the Resale Registration Statement shall not have
been declared effective by the SEC (the “Late Registration
Payment”).  Such Late Registration Payment shall be paid to the
Investors within 30 days after the end of each month in which such Late
Registration Payment shall be payable, and until the Company shall have complied
with the provisions of this Section 5b.

    

    Without
limiting any of the other rights of the holders of Registrable Securities
hereunder, the failure by the Company to timely make any or all of such Late
Registration Payments shall constitute an Event of Default under the
Notes.

    

    Notwithstanding
the foregoing, the aggregate amount of the Late Registration Payment shall: (a)
not exceed ten percent (10%) of the aggregate principal amount of the Notes or
aggregate Stated Value of the Series A Preferred Stock (as applicable); and (b)
in the event that the Company complies with Section 5b(i) above, but the
effectiveness of such Resale Registration Statement is delayed beyond such 150
day period solely by reason of comments from the SEC relating to the application
of Rule 415, as promulgated under the Securities Act, then the Late Payment
shall be based on two percent (2%) of the portion of the Investor’s initial
investment in the Notes that corresponds to the number of such Investor’s
Registrable Securities permitted to be registered by the Commission pursuant to
Rule 415.

    

    c.           Notwithstanding anything to the
contrary contained in this Section 5, in the event that the SEC, in its
application of Rule 415 as promulgated under the Securities Act, requires any
holder of Registrable Securities to be deemed to be a statutory underwriter,
then and in such event the Company may reduce the number of shares being
registred under such Resale Registration Statement in order to avoid such
statutory underwriter designation (if possible), or, at the request of the
holders of a majority of the Registrable Securities, the Company shall reduce or
withdraw such Resale Registration Statement, as
applicable.  In the event the
Commission does not permit the Company to register all of the Registrable
Securities in the initial Registration Statement, the Company shall use its best
efforts to register the Registrable Securities, subject to the terms of this
Section 2, that were not registered in the initial Registration Statement, as
promptly as possible and in a manner permitted by the Commission, whether by
filing a subsequent registration statement as soon as the Commission permits the
Company to do so, providing demand registration rights, or
otherwise.

    

    6.     
      Piggyback
Registration.

    

    a.           If
at any time or from time to time, the Company shall determine to register any of
its securities, for its own account or the account of any of its shareholders,
other than (A) a registration relating solely to employee benefit plans, (B) a
registration relating solely to an SEC Rule 145 transaction, or (C) a
Registration Statement on any form (excluding Form SB-2, S-1, S-3, F-1 or F-3,
or their successor forms) which does not include substantially the same
information as would be required to be included in a Resale Registration
Statement covering the sale of Registrable Securities, the Company
will:

    
      
         

      

      
        - 5 -

        
          

        

      

      
         

      

    

    

    i.           give
to each Holder written notice thereof as soon as practicable prior to filing the
Registration Statement; and

    

    ii.           use
its best efforts include in such registration and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made within fifteen (15) days after receipt of such written notice
from the Company, by any Holder or Holders, except as set forth in subsection
6(b) below.

    

    b.           If
the registration is for a registered public offering involving an underwriting,
the Company shall so advise the Holders as a part of the written notice given
pursuant to Section 6(a)(i).  In such event, the right of any Holder
to registration pursuant to Section 6 shall be conditioned upon such Holder’s
participation in such underwriting and the inclusion of such Holder’s
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company and the other holders distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting by the
Company.  Notwithstanding any other provision of this Section 6, it is
anticipated and, by their execution of this Agreement, each Holder acknowledges,
that the managing underwriter(s):

    

    (i)           
may require that each Holder including Registrable Securities in such registered
underwritten public offering agree to “lock up” such Registrable Securities and
refrain from effecting any sale of distribution of such Registrable Securities
for a period of up to one hundred and eighty (180) days following the effective
date of the Registration Statement in respect of such underwritten public
offering by the Company; or

    

    (ii)           may
determine that marketing factors require: (A) either a limitation on the number
of shares to be underwritten, in which event, the managing underwriter(s) may
limit the number of Registrable Securities to be included in the registration
and underwriting; or (B) that all of the
Registrable Securities must be excluded entirely from such underwritten public
offering registration for the Company (provided that no shares held by officers
and directors of the Company, other than Registrable Securities that may be
owned by officers and directors, shall be included in the registration and
underwriting).

    

    c.           The
Company shall so advise all Holders and the other Holders distributing their
securities through such underwriting pursuant to piggyback registration rights
similar to this Section 6, and the number of shares of Registrable Securities
and other securities that may be included in the registration and underwriting
shall be allocated among all Holders and other holders in proportion, as nearly
as practicable, to the respective amounts of Registrable Securities held by such
Holders and other securities held by other holders at the time of filing the
Registration Statement. If any Holder disapproves of the terms of any such
underwriting, he may elect to withdraw therefrom by written notice to the
Company and the managing underwriter. If, by the withdrawal of such Registrable
Securities, a greater number of Registrable Securities held by other Holders may
be included in such registration (up to the limit imposed by the underwriters),
the Company shall offer to all Holders who have included Registrable Securities
in the registration the right to include additional Registrable Securities. Any
Registrable Securities excluded or withdrawn from such underwriting shall be
withdrawn from such registration.

    
      
         

      

      
        - 6 -

        
          

        

      

      
         

      

    

    

    7.       
    Expenses
of Registration.  In addition to the fees and expenses
contemplated by Section 8 hereof, all expenses incurred in connection with all
registrations pursuant to Section 5 or Section 6 hereof, including without
limitation all registration, filing and qualification fees, printing expenses,
and all fees and disbursements of counsel for the Company and any reasonable
fees for legal counsel to the Investor and all other Holders of Registrable
Securities (provided that any fees for counsel shall be approved by the Company
in writing in advance if greater then $10,000), and expenses of any special
audits of the Company’s financial statements incidental to or required by such
registration, shall be borne by the Company, except that the Company shall not
be required to pay underwriters’ fees, discounts or commissions relating to
Registrable Securities or fees of a separate legal counsel of a Holder other
than the counsel described above.

    

    8.      
     Registration
Procedures.  In the case of each registration affected by the
Company pursuant to this Agreement, the Company will keep each Holder
participating therein advised in writing as to the initiation of each
registration and as to the completion thereof. In addition, at its expense the
Company will:

    

    a.           keep

Securities Act;

    

    b.           promptly

9(a) above;

jurisdiction, at the earliest possible moment;

    

    e.           register
or qualify such Registrable Securities for offer and sale under the securities
or blue sky laws of such jurisdictions as any Holder or underwriter reasonably
requires, and keep such registration or qualification effective during the
period set forth in Section 8(a) above;

    f.           cause
all Registrable Securities covered by such registrations to be listed or quoted

securities issued by the Company are then listed or quoted,

    

    g.           enter
into such customary agreements (including underwriting agreements in customary
form) and take all such other actions as the holders of a majority of the
Registrable Securities being sold or the underwriters, if any, reasonably,
request in order to expedite or facilitate the disposition of such Registrable
Securities (including, without limitation, effecting a stock split or a
combination of shares);

    

    h.           make
available for inspection upon reasonable request by any seller of Registrable
Securities  and any attorney, accountant or other agent retained by

each Holder, at any time a prospectus covered by such Registration Statement is
required to be delivered under the Securities Act, of the happening of any event
of which it has knowledge as a result of which the prospectus included in such
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing;

    

    j.           notify
the Holders of Registrable Securities as promptly as possible (and, in the case
of (i)(A) below, not less than three (3) days prior to such filing, and in the
case of (iii) below, on the same day of receipt by the Company of such notice
from the Commission) and (if requested by any such Person) confirm such notice
in writing no later than two (2) Business Days following the day (i)(A) when a
Prospectus or any Prospectus supplement or post-effective amendment to the
Registration Statement is filed; (B) when the Commission notifies the Company
whether there will be a "review" of such Registration Statement and whenever the

respect to the Registration Statement or any post-effective amendment, when the
same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to the

    9.      
     Indemnification.

    

    a.           In
the event of a registration of any of the Registrable Securities under the
Securities Act pursuant to Section 5 or Section 6 of this Agreement, the Company
will indemnify and hold harmless each Holder of such Registrable Securities
thereunder and each other person, if any, who controls such Holder within the
meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which such Holder, underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement under which such
Registrable Securities were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, or any violation by the Company of any
rule or regulation promulgated under the Securities Act or any state securities
law applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration, and will reimburse each such
Holder, each of its officers, directors and partners, and each person
controlling such Holder, each such underwriter and each person who controls any
such underwriter, for any reasonable legal and any other expenses incurred in
connection with investigating, defending or settling any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage or liability arises
out of or is based on any untrue statement or omission based upon written
information furnished to the Company by an instrument duly executed by such
Holder or underwriter specifically for use therein.

    

    b.           Each
Holder will, if Registrable Securities held by or issuable to such Holder are
included in the securities as to which such registration is being effected,
indemnify and hold harmless the Company, each of its directors and officers,
each underwriter, if any, of the Company’s securities covered by such a
Registration Statement, each person who controls the Company and each
underwriter within the meaning of the Securities Act, and each other such
Holder, each of its officers, directors and partners and each person controlling
such Holder, against all claims, losses, expenses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such Registration
Statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
the Company, such Holders, such directors, officers, partners, persons or
underwriters for any reasonable legal or any other expenses incurred in
connection with investigating, defending or settling any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such Registration Statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder
specifically for use therein; provided, however, the total amount for
which any Holder, its officers, directors and partners, and any person
controlling such Holder, shall be liable under this Section 9(b) shall not in
any event exceed the aggregate proceeds received by such Holder from the sale of
Registrable Securities sold by such Holder in such
registration.

    c.           Each
party entitled to indemnification under this Section 9 (the “Indemnified Party”) shall give
notice to the party required to provide indemnification (the “Indemnifying Party”) promptly
after such Indemnified Party has actual knowledge of any claims as to which
indemnity may be sought, and shall permit the Indemnifying Party to assume the
defense of any such claim or any litigation resulting therefrom, provided that
counsel for the Indemnifying Party, who shall conduct the defense of such claim
or litigation, shall be approved by the Indemnified Party (whose approval shall
not be unreasonably withheld), and the Indemnified Party may participate in such
defense at such party’s expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations hereunder, unless such failure resulted in
actual detriment to the Indemnifying Party. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect of such claim or litigation.

    

    d.           Notwithstanding
the foregoing, to the extent that the provisions on indemnification contained in
the underwriting agreements entered into among the selling Holders, the Company
and the underwriters in connection with the underwritten public offering are in
conflict with the foregoing provisions, the provisions in the underwriting
agreement shall be controlling as to the Registrable Securities included in the
public offering;

    

    e.           If
the indemnification provided for in this Section 9 is held by a court of
competent jurisdiction to be unavailable to an indemnified party with respect to
any loss, liability, claim, damage or expense referred to therein, then the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, liability, claim, damage or expense in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other hand in connection with the
statements or omissions which resulted in such loss, liability, claim, damage or
expense as well as any other relevant equitable considerations. The relevant
fault of the indemnifying party and the indemnified party shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission to state a material fact relates to
information supplied by the indemnifying party or by the indemnified party and
the parties’ relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. Notwithstanding the foregoing,
the amount any Holder shall be obligated to contribute pursuant to this Section
9(e) shall be limited to an amount equal to the proceeds to such Holder of the
Restricted Securities sold pursuant to the Registration Statement which gives
rise to such obligation to contribute (less the aggregate amount of any damages
which the Holder has otherwise been required to pay in respect of such loss,
claim, damage, liability or action or any substantially similar loss, claim,
damage, liability or action arising from the sale of such Restricted
Securities).

    

    f.           The
indemnification provided by this Section 9 shall be a continuing right to
indemnification and shall survive the registration and sale of any securities by
any Person entitled to indemnification hereunder and the expiration or
termination of this Agreement.

    10.          Information
by Holder.  The Holder or Holders of Registrable Securities
included in any registration shall promptly furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may reasonably request in writing and as
shall be required in connection with any registration referred to
herein.

    

    11.          Rule 144
Reporting.  With a view to making available to Holders of
Registrable Securities the benefits of certain rules and regulations of the SEC
which may permit the sale of the Registrable Securities to the public without
registration, the Company agrees at all times to file with the Commission all
reports and other documents required of the Company under the Securities Act and
the Exchange Act.

    

    12.          Transfer
of Registration Rights.  The rights to cause the Company to
register Registrable Securities of a Holder and keep information available
granted to a Holder by the Company under Section 5 or Section 6 of this
Agreement may be assigned by a Holder to any partner or shareholder of such
Holder, to any other Holder, or to a transferee or assignee; provided, that the
Company is given written notice by the Holder at the time of or within a
reasonable time after said transfer, stating the name and address of said
transferee or assignee and identifying the securities with respect to which such
registration rights are being assigned.

    

    13.          Termination
of Rights.  The rights of any particular Holder to cause the
Company to register securities under Section 5 or Section 6 of this Agreement
shall terminate with respect to such Holder at such time that such Holder is
able to dispose of all of such Holder’s Registrable Securities (i) in one
three-month period pursuant to the provisions of Rule 144, provided that such
Holder holds not more than one percent (1%) of the outstanding voting stock of
the Company, or (ii) otherwise pursuant to the provisions of Rule
144.

    

    14           Remedies
upon Default or Delay.  Without limitation of any other remedy
available to a Holder under applicable law or otherwise, if the Company shall
(1) fail to register Registrable Securities after it shall have been requested
to do so by a Holder or otherwise required to do so in accordance with Section 5
or Section 6 of this Agreement, or (2) fail to perform any of its obligations
hereunder and as a result of such failure Holders have not been able to sell
their Registrable Securities, or (3) act or fail to act in any manner such that
one or more Holders have been delayed in the sale of their Registrable
Securities, which delay is not expressly permitted by this Agreement, then any
Holder adversely affected by such action, failure or delay shall be entitled to
the relief set forth in Section 5 or Section 6 above.

    

    15.          Miscellaneous.

    

    a.           Amendments. This
Agreement may be amended only by a writing signed by the Holders of a majority
of the Registrable Securities, as constituted from time to time. The Holders
hereby consent to future amendments to this Agreement that permit future
investors, other than employees, officers or directors of the Company, to be
made parties hereto and to become Holders of Registrable Securities; provided, however, that no such future
amendment (even if approved by Holders of a majority of the Registrable
Securities), may materially impair or adversely affect the rights of the Holders
hereunder without obtaining the requisite consent of the effected Holders, as
set forth above. For purposes of this Section, Registrable Securities held by
the Company or beneficially owned by any officer or employee of the Company
shall be disregarded and deemed not to be outstanding.

provision of this Agreement shall be held to be illegal, invalid or
unenforceable, such illegality, invalidity or unenforceability shall attach only
to such provision and shall not in any manner affect or render illegal, invalid
or unenforceable any other provision of this Agreement, and this Agreement shall
be carried out as if any such illegal, invalid or unenforceable provision were
not contained herein.

Agreement shall be governed by and construed under the laws of the State of New
York without regard to principles of conflict of law.

    A.           Voluntary
Conversion

     

    (i)           Conversion.                                Holders
of shares of Series A Preferred Stock may at their option convert all or any
portion of their shares of Series A Preferred Stock into Common Stock of the
Corporation at any time or from time to time, following the Issuance Date (a
“Conversion”).

     

    (ii)           In
the event of a Conversion, each of the shares of Series A Preferred Stock shall
be convertible into that number of Conversion Shares as shall be determined
by:

     

    (x)           multiplying
the number of shares of Series A Preferred Stock being converted, by the
$1,000.00 Stated Value per share of Series A Preferred Stock; and

     

    (y)           dividing
the product of (x) above, by the Conversion Price per share, in effect as of the
date an Investor faxes (or otherwise delivers) a Notice of Conversion to the
Corporation.

     

    The
foregoing formula shall be subject to adjustment as provided in clause (v) of
Paragraph B below.

     

    B.           Mechanics of Voluntary
Conversion. In order to effect an Conversion, a Holder of shares of
Series A Preferred Stock shall: (i) fax (or otherwise deliver) a copy of the
fully executed Notice of Conversion to the Corporation (Attention: Secretary)
and (ii) surrender or cause to be surrendered the original certificates
representing the Series A Preferred Stock being converted (the “Series A Preferred Stock
Certificates”), duly endorsed, along with a copy of the Notice of
Conversion as soon as practicable thereafter to the Corporation.  Upon
receipt by the Corporation of a facsimile copy of a Notice of Conversion from a
Holder, the Corporation shall promptly send, via facsimile, a confirmation to
such Holder stating that the Notice of Conversion has been received, the date
upon which the Corporation expects to deliver the Common Stock issuable upon
such conversion and the name and telephone number of a contact person at the
Corporation regarding the conversion.  The Corporation shall not be
obligated to issue shares of Common Stock upon a conversion unless either the
Series A Preferred Stock Certificates are delivered to the Corporation as
provided above, or the Holder notifies the Corporation that such Series A
Preferred Stock Certificates have been lost, stolen or destroyed and delivers
the documentation to the Corporation required by Article X. B
hereof.

    (i)           Delivery of Common Stock
Upon Conversion. Upon the surrender of Series A Preferred Stock
Certificates accompanied by a Notice of Conversion, the Corporation (itself, or
through its transfer agent, as appropriate) shall, no later than the later of
(a) the fifth (5th) Business Day following the Conversion Date and (b) the
Business Day immediately following the date of such surrender (or, in the case
of lost, stolen or destroyed certificates, after provision of indemnity pursuant
to Article XI B) (the “Delivery Period”),
issue and deliver (i e., deposit with a nationally recognized overnight courier
service portage prepaid) to the Holder or its nominee (x) that number of shares
of Common Stock issuable upon conversion of such shares of Series A Preferred
Stock being converted and (y) a certificate representing the number of shares of
Series A Preferred Stock not being converted, if any.  Notwithstanding
the foregoing, the Holder of Series A Preferred Stock shall, for all purposes,
be deemed to be a record owner of that number of shares of Common Stock issuable
upon conversion of those shares of Series A Preferred Stock set forth in the
Conversion Notice as at the date of such Conversion Notice.  In
addition, if the Corporation's transfer agent is participating in the Depository
Trust Corporation (“DTC”) Fast Automated
Securities Transfer program, and so long as the certificates therefor do not
bear a legend (pursuant to the terms of the Securities Purchase Agreement) and
the Holder thereof is not then required to return such certificate for the
placement of a legend thereon (pursuant to the terms of the Securities Purchase
Agreement), the Corporation shall cause its transfer agent to promptly
electronically transmit the Common Stock issuable upon conversion to the Holder
by crediting the account of the Holder or its nominee with DTC through its
Deposit Withdrawal Agent Commission system (“DTC
Transfer”).  If the aforementioned conditions to a DTC Transfer
are not satisfied, the Corporation shall deliver as provided above to the Holder
physical certificates representing the Common Stock issuable upon conversion.
Further, a Holder may instruct the Corporation to deliver to the Holder physical
certificates representing the Common Stock issuable upon conversion in lieu of
delivering such shares by way of DTC Transfer.

     

    (ii)           Taxes. The
Corporation shall pay any and all taxes that may be imposed upon it respect to
the issuance and delivery of the shares of Common Stock upon the conversion of
the Series A Preferred Stock.

     

    (iii)           No Fractional
Shares.  If any conversion of Series A Preferred Stock would
result in the issuance of a fractional share of Common Stock (aggregating all
shares of Series A Preferred Stock being converted pursuant to a given Notice of
Conversion), such fractional share shall be payable in cash based upon the
Conversion Price per share, and the number of shares of Common Stock issuable
upon conversion of the Series A Preferred Stock shall be the next lower whole
number of shares.  If the Corporation elects not to, or is unable to,
make such a cash payment, the Holder shall be entitled to receive, in lieu of
the final fraction of a share, one whole share of Common Stock.

     

    (iv)           Conversion
Disputes.   In the case of any dispute with respect to a
conversion, the Corporation shall promptly issue such number of shares of Common
Stock in accordance with subparagraph (i) above as are not disputed. If such
dispute involves the calculation of the Conversion Price, and such dispute is
not promptly resolved by discussion between the relevant Holder and the
Corporation, the Corporation and the Holder shall submit their disputed
calculations to an independent outside accountant via facsimile within three
Business Days of receipt of the Notice of Conversion. The accountant, at the
Corporation's sole expense, shall promptly audit the calculations and notify the
Corporation and the Holder of the results no later than three Business Days from
the date it receives the disputed calculations. The accountant's calculation
shall be deemed conclusive, absent manifest error. The Corporation shall then
issue the appropriate number of shares of Common Stock in accordance with
subparagraph (i) above.

     

    (v)           Payment of Accrued
Amounts.  Upon conversion of any shares of Series A Preferred
Stock, all amounts then accrued or payable on such shares under this Certificate
of Designation (including, without limitation, all Dividends) or the
Registration Rights Agreement through and including the Conversion Date shall be
paid by the Corporation in cash or at the Corporation's option in stock, or, in
the case of any Dividend, in the manner described in Article III.  In
the event that the Corporation elects to effect a payment-in-kind, the number of
fully paid and non-assessable shares of Common Stock due shall be determined in
accordance with the following formula:

    
      
         

      

      
        4

        
          

        

      

      
         

      

    

     

    (A)           multiplying
the number of shares of Series A Preferred Stock being converted, by the sum of
(x) the $1,000.00 Stated Value per share of Series A Preferred Stock, and (y)
the product of multiplying the per share dollar value of all accrued dividends
that was paid in additional shares of Preferred Stock; and the number of shares
of Series A Preferred Stock being converted; and

     

    (B)           dividing
the product of (A) above, by the Conversion Price per share, in effect as of the
date a Notice of Conversion shall be given to the Corporation.

     

    C.           Mandatory Conversion.
Subject to Section D of this Article III, the number of outstanding shares of
Series A Preferred Stock referred to below in Section C of this Article
III:  (i) on the Mandatory Conversion Date shall, automatically and
without any action on the part of the holder thereof, convert into a number of
fully paid and non-assessable shares of Common Stock equal to the quotient of
(i) the Liquidation Preference Amount of the number of shares of Series A
Preferred Stock being converted on the Mandatory Conversion Date divided by (ii)
the Conversion Price in effect on the Mandatory Conversion Date.

     

    (i)           As
used herein, "Mandatory Conversion
Date" shall mean, with respect to all outstanding shares of Series A
Preferred Stock at such time, that date that is three (3) years following the
Issuance Date; provided, that, (i) the
registration statement providing for the resale of shares of the Common Stock
issuable upon conversion of the Series A Preferred Stock is effective and has
been effective, without lapse or suspension of any kind, for a period sixty (60)
consecutive calendar days, or the shares of Common Stock into which the Series A
Preferred Stock can be converted may be offered for sale to the public pursuant
to Rule 144 ("Rule 144") under the Securities Act of 1933, as amended, (ii)
trading in the Common Stock shall not have been suspended by the Securities and
Exchange Commission or the OTC Bulletin Board (or other exchange or market on
which the Common Stock is trading), and (iii) the Company is in material
compliance with the terms and conditions of this Certificate of Designation and
the other Transaction Documents (as defined in the Securities Purchase
Agreement).  Notwithstanding the foregoing, the Mandatory Conversion
Date shall be extended for as long as (a) a Triggering Event (as defined below)
shall have occurred and be continuing, or (b) any event shall have occurred and
be continuing which with the passage of time and the failure to cure would
result in a Triggering Event.  The Mandatory Conversion Date and the
Voluntary Conversion Date collectively are referred to in this Certificate of
Designation as the "Conversion Date."

     

    
      	
               
      

            	
              (A)

            	
              "Triggering
      Event".  A "Triggering Event" shall be deemed to have
      occurred at such time as any of the following
  events:

            

    

     

    
      	
               
      

            	
              (a)

            	
              so
      long as any shares of Series A Preferred Stock are outstanding, the
      effectiveness of the Registration Statement, after it becomes effective,
      (i) lapses for any reason (including, without limitation, the issuance of
      a stop order) and such lapse continues for a period of twenty (20)
      consecutive trading days, or (ii) is unavailable to the holder of the
      Series A Preferred Stock for sale of the shares of Common Stock, and such
      lapse or unavailability continues for a period of twenty (20) consecutive
      trading days, and the shares of Common Stock into which such holder's
      Series A Preferred Stock can be converted cannot be sold in the public
      securities market pursuant to Rule 144 (“Rule 144”) under the Securities
      Act of 1933, as amended, provided that
      the cause of such lapse or unavailability is not due to factors solely
      within the control of such holder of Series A Preferred
    Stock.

              (b)

            	
              the
      suspension from listing, without subsequent listing on any one of, or the
      failure of the Common Stock to be listed on at least one of, the OTC
      Bulletin Board, the Nasdaq Global Market, the Nasdaq Capital Market, or
      any of the NYSE Euronext’s exchanges for a period of five (5) consecutive
      trading days;

      Company's notice to any holder of Series A Preferred Stock, including by
      way of public announcement, at any time, of its inability to comply or its
      intention not to comply with proper requests for conversion of any Series
      A Preferred Stock into shares of Common Stock;
  or

            

    

     

    
      	
               
      

            	
              (d)

            	
              the
      Company's failure to comply with a Conversion Notice tendered in
      accordance with the provisions of this Certificate of Designation within
      ten (10) business days after the receipt by the Company of the Conversion
      Notice and the Preferred Stock Certificates;
or

            

    

     

    
      	
               
      

            	
              (e)

            	
              the
      Company deregisters its shares of Common Stock and as a result such shares
      of Common Stock are no longer publicly traded;
  or

            

    

     

    
      	
               
      

            	
              (f)

            	
              the
      Company consummates a “going private” transaction and as a result the
      Common Stock is no longer registered under Sections 12(b) or 12(g) of the
      Securities Exchange Act of 1934, as amended;
or

            

    

     

    
      	
               
      

            	
              (g)

            	
              the
      Company breaches any representation, warranty, covenant or other term or
      condition of the Securities Purchase Agreement, this Certificate of
      Designation or any other agreement, document, certificate or other
      instrument delivered in connection with the transactions contemplated
      thereby or hereby, except to the extent that such breach would not have a
      Material Adverse Effect (as defined in the Securities Purchase Agreement)
      and except, in the case of a breach of a covenant which is curable, only
      if such breach continues for a period of a least ten (10) business
      days.

            

    

     

    (ii)          On
the Mandatory Conversion Date, the outstanding shares of Series A Preferred
Stock shall be converted automatically without any further action by the holders
of such shares and whether or not the certificates representing such shares are
surrendered to the Company or its Transfer Agent; provided, however, that the
Company shall not be obligated to issue the shares of Common Stock issuable upon
conversion of any shares of Series A Preferred Stock unless certificates
evidencing such shares of Series A Preferred Stock are either delivered to the
Company or the holder notifies the Company that such certificates have been
lost, stolen, or destroyed, and executes an agreement satisfactory to the
Company to indemnify the Company from any loss incurred by it in connection
therewith.  Upon the occurrence of a Mandatory Conversion of the
Series A Preferred Stock pursuant to this Section III, the holders of the Series
A Preferred Stock shall surrender the certificates representing the Series A
Preferred Stock for which the Mandatory Conversion Date has occurred to the
Company and the Company shall cause its Transfer Agent to deliver the shares of
Common Stock issuable upon such conversion (in the same manner set forth in
Section III.B) to the holder within three (3) business days of the holder's
delivery of the applicable Preferred Stock Certificates.

    D.           Limitations on
Conversion.

     

    (i)           Notwithstanding
anything to the contrary set forth in this Certificate, at no time may a Holder
of Series A Preferred Stock convert their shares of Series A Preferred Stock if
the number of shares of Common Stock to be issued pursuant to such conversion
would cause the number of shares of Common Stock owned by such Holder at such
time to exceed, when aggregated with all other shares of Common Stock owned by
such Holder and its affiliates at such time, the number of shares of Common
Stock which would result in such Holder, its affiliates, any investment manager
having discretionary investment authority over the accounts or assets of such
Holder, or any other persons whose beneficial ownership of Common Stock would be
aggregated with such Holder’s for purposes of Section 13(d) and Section 16 of
the Exchange Act, beneficially owning (as determined in accordance with Section
13(d) of the Exchange Act and the rules thereunder) in excess of 9.99% of the
then issued and outstanding shares of Common Stock; provided, however, that upon
a Holder of Series A Preferred Stock providing the Corporation with sixty-one
(61) days notice (pursuant to this certificate) (the “Waiver Notice”) that such
Holder would like to waive this Section C(b) with regard to any or all shares of
Common Stock issuable upon conversion of Series A Preferred Stock, this Section
C(b) shall be of no force or effect with regard to those shares of Series A
Preferred Stock referenced in the Waiver Notice.

     

    E.           Concerning the Conversion
Shares.

     

    (i)           Legend.  The
Conversion Shares issuable upon conversion of the Preferred Stock may not be
sold or transferred unless (A) such shares are sold pursuant to an effective
registration statement under the Securities Act, or (B) the Corporation or its
transfer agent shall have been furnished with an opinion of counsel (which
opinion shall be in form, substance and scope customary for opinions of counsel
in comparable transactions) to the effect that the shares to be sold or
transferred may be sold or transferred pursuant to an exemption from such
registration or (C) such shares are sold or transferred pursuant to Rule
144 under the Securities Act (or a successor rule) (“Rule 144”) or (D) such
shares are sold or transferred outside the United States in accordance with
Regulation S under the Securities Act, or (E) such shares are transferred to an
“affiliate” (as defined in Rule 144) of the Corporation who agrees to sell or
otherwise transfer the shares only in accordance with this
Section.  Except as otherwise provided herein (and subject to the
removal provisions set forth below), until such time as the Conversion Shares
have been registered under the Securities Act of 1933, as amended (the “Act”) as contemplated
by the Registration Rights Agreement, or otherwise may be sold pursuant to Rule
144 without any restriction as to the number of securities as of a particular
date that can then be immediately sold, each certificate for Conversion Shares
that has not been so included in an effective registration statement or that has
not been sold pursuant to an effective registration statement or an exemption
that permits removal of the legend, shall bear a legend substantially in the
following form, as appropriate:

     

    THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”).  THE
HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES THAT SUCH SECURITIES MAY BE
OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE
CORPORATION, (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF
REGULATION S UNDER THE U.S. SECURITIES ACT, (C) WITHIN THE UNITED STATES
AFTER REGISTRATION OR IN ACCORDANCE WITH THE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS UNDER THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF
APPLICABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, OR
(D) WITHIN THE UNITED STATES IN A TRANSACTION THAT DOES NOT REQUIRE
REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES
LAWS AND THE HOLDER HAS PRIOR TO SUCH SALE FURNISHED TO THE CORPORATION AN
OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE CORPORATION.

     

    (ii)           Removal of
Legend.  The legend set forth above shall be removed and the
Corporation shall issue to the Holder a new certificate therefor free of any
transfer legend only if (A) the Corporation or its transfer agent shall have
received an opinion of counsel, in form, substance and scope acceptable to the
Corporation, to the effect that a public sale or transfer of such Conversion
Shares may be made without registration under the Act and the shares are so sold
or transferred, or (B) the Conversion Shares are registered for sale by the
Holder under an effective registration statement filed under the Act. Nothing in
the Preferred Stock shall affect in any way the Holder’s obligations to comply
with applicable prospectus delivery requirements upon the resale of the
securities referred to herein.

      IV.  RESERVATION
OF SHARES OF COMMON STOCK

    

    

    A.           Reserved
Amount.   On or prior to the Issuance Date, the
Corporation shall reserve not less than 12,000,000 shares of its authorized but
unissued shares of Common Stock for issuance upon conversion of the Series A
Preferred Stock, and, thereafter, the number of authorized but unissued shares
of Common Stock so reserved (the “Reserved Amount”)
shall at all times be sufficient to provide for the full conversion of all of
the Series A Preferred Stock (including any Dividend payable thereon)
outstanding at the current Conversion Price thereof.

     

    B.           Increases to Reserved
Amount. During the period that the Corporation remains privately held and
not listed on any recognized stock exchange in the United States or abroad or
the OTC Bulletin Board, the Corporation shall, twice annually, review the
Reserved Amount for any stock splits, or dividends on the Series A Preferred
Stock, or similar situations to determine whether the Reserved Amount needs to
be increased.

     

    
      V.  RANK

    

     

    All
shares of the Series A Preferred Stock shall rank (i) senior to
the Corporation's Series B Preferred Stock, the Corporation’s Common Stock and
any other class of securities which is specifically designated as junior to the
Series A Preferred Stock (collectively, with the Common Stock, the “Junior Securities”);
(ii) senior to
or pari
passu with
any other class or series of Preferred Stock of the Corporation hereafter
created specifically ranking, by its terms, on parity with the Series A
Preferred Stock (the “Pari Passu
Securities”); and (iii) junior to
any class or series of capital stock of the Corporation hereafter created (with
the written consent of the Majority Holders obtained in accordance with Article
IX hereof) specifically ranking, by its terms, senior to the Series A Preferred
Stock (collectively, the “Senior Securities”),
in each case as to distribution of assets upon liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary.

     

    
      VI.  LIQUIDATION
PREFERENCE

    

     

    A.           In
the event of a merger, sale (of substantially all assets or stock), any
voluntary or involuntary liquidation, dissolution or winding up of the affairs
of the Corporation, then, either (i) after any distribution or payment on Senior
Securities, (ii) simultaneous with any distribution or payment on Pari Passu
Securities, and (iii) before any distribution or payment shall be made to the
Holders of the Common Stock or any other Junior Securities, each Holder of
Series A Preferred Stock then outstanding shall be entitled to be paid, out of
the assets of the Corporation available for distribution to its stockholders, an
amount (the “Liquidation
Preference”) equal to (i) aggregate number of shares of Series A
Preferred Stock then outstanding multiplied by its Stated Value per share; and
(ii) any accrued but unpaid Dividends.  If the assets of the
Corporation are not sufficient to generate cash sufficient to pay in full the
Liquidation Preference, then the Holders of Series A Preferred Stock shall share
ratably (together with holders of any Pari Passu Securities) in any distribution
of cash generated by such assets in accordance with the respective amounts that
would have been payable in such distribution as if the amounts to which the
Holders of outstanding shares of Series A Preferred Stock are entitled were paid
in full.

      VII.  ADJUSTMENTS

    

     

    The
Conversion Price and the number of Conversion Shares, as the case may be, shall
be subject to adjustment from time to time as provided in this Section VII;
provided, that the
anti-dilution adjustments contemplated by Section E below shall expire on a date
which shall be the twelve (12) month anniversary of the effective date of the
Registration Statement.   In the event that any adjustment of the
Conversion Price as required herein results in a fraction of a cent, such
Conversion Price shall be rounded down to the nearest cent.

     

    A.           Reorganization,
Consolidation, Merger, etc.; Reclassification.  In case at any
time or from time to time, the Corporation shall effect any merger,
reorganization, restructuring, reverse stock split, consolidation, sale of all
or substantially all of the Corporation’s assets or any similar transaction or
related transactions (each such transaction, a “Fundamental Change”),
then, in each such case, as a condition to the consummation of such a
transaction, proper and adequate provision shall be made by the Corporation
whereby the Holder of the Series A Preferred Stock, on the exercise hereof, at
any time after the consummation of such Fundamental Change, shall receive, in
lieu of the Conversion Shares issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such Holder would have been entitled upon such
consummation of a Fundamental Change if such Holder had so exercised the Series
A Preferred Stock, immediately prior thereto.

     

    If the
Corporation at any time shall, by reclassification or otherwise, change the
Common Stock into the same or a different number of securities of any class or
classes that may be issued or outstanding, the Series A Preferred Stock shall
thereafter be deemed to evidence the right to purchase an adjusted number of
such securities and kind of securities as would have been issuable as the result
of such change with respect to the Common Stock immediately prior to such
reclassification or other change.

    

    B.           Dissolution.  In
the event of any dissolution of the Corporation following the transfer of all or
substantially all of its properties or assets, the Corporation, prior to such
dissolution, shall at its expense deliver or cause to be delivered the stock and
other securities and property (including cash, where applicable) receivable by
the Holder of the Series A Preferred Stock after the effective date of such
dissolution pursuant to this Article to a bank or trust company (a “Trustee”) as
trustee for the Holder of the Series A Preferred Stock.

     

    C.           Continuation of
Terms.  Upon any Fundamental Change or transfer (and any
dissolution following any transfer) referred to in this Article, the Series A
Preferred Stock shall continue in full force and effect and the terms hereof
shall be applicable to any other securities and property receivable on the
exercise of the Series A Preferred Stock after the consummation of such
Fundamental Change or transfer or the effective date of dissolution following
any such transfer, as the case may be, and shall be binding upon the issuer of
any other securities, including, in the case of any such transfer, the person
acquiring all or substantially all of the properties or assets of the
Corporation, whether or not such person shall have expressly assumed the terms
of the Series A Preferred Stock as provided in Section 4(d). In the event the
Series A Preferred Stock does not continue in full force and effect after the
consummation of the transaction described in this Section, then only in such
event will the Corporation’s securities and property (including cash, where
applicable) receivable by the Holder of the Warrants be delivered to the Trustee
as contemplated by Section 4(b).

    
      
         

      

      
        9

        
          

        

      

      
         

      

    

    D.           Extraordinary Events
Regarding Common Stock.  In the event that the Corporation
shall (a) issue additional shares of Common Stock as a dividend or other
distribution on outstanding Common Stock, (b) subdivide its outstanding shares
of Common Stock, or (c) combine its outstanding shares of the Common Stock into
a smaller number of shares of the Common Stock, then, in each such event, the
Conversion Price shall, simultaneously with the happening of such event, be
adjusted by multiplying the then Conversion Price by a fraction, the numerator
of which shall be the number of shares of Common Stock outstanding immediately
prior to such event and the denominator of which shall be the number of shares
of Common Stock outstanding immediately after such event, and the product so
obtained shall thereafter be the Conversion Price then in effect. The Conversion
Price, as so adjusted, shall be readjusted in the same manner upon the happening
of any successive event or events described in this Section VIID. The number of
Conversion Shares that the Holder of the Series A Preferred Stock shall
thereafter, on the exercise hereof as provided in this Section, be entitled to
receive shall be adjusted to a number determined by multiplying the number of
Conversion Shares that would otherwise (but for the provisions of this Section)
be issuable on such exercise by a fraction of which (a) the numerator is the
Conversion Price that would otherwise (but for the provisions of this Section)
be in effect, and (b) the denominator is the Conversion Price in effect on the
date of such exercise.

     

    E.           Subsequent
Offerings.  If the Corporation shall issue any shares of its
Common Stock, or any other note, debenture, warrant, option or other security
that is at any time convertible into or exercisable or exchangeable for, or
otherwise entitles the holder thereof to receive Common Stock (each a “Common Stock
Equivalent” and collectively, “Common Stock
Equivalents”) at a price per share that shall be less than the Conversion
Price in effect on such date (the “Subsequent Offering
Price”), the Conversion Price shall be adjusted downward to a price
determined by multiplying the Conversion Price by the following quotient
(expressed in decimal form):

     

    (a).           the
sum of (i) the Conversion Price in effect before the issuance of such new
securities multiplied by the number of shares of the Corporation’s Common Stock
then issued and outstanding and (ii) the consideration, if any, received by or
deemed to have been received by the Corporation on the issue of such new Common
Stock or Common Stock Equivalent by:

     

    (b).           the
sum of (i) the number of shares of the Corporation’s Common Stock then issued
and outstanding immediately prior to the issuance of such new securities and
(ii) the number of additional shares of Common Stock issued or issuable in
connection with the issuance of such Common Stock Equivalents.

     

    Notwithstanding
the foregoing, no adjustment in the Conversion Price shall be made for shares of
Common Stock issued or Common Stock Equivalents issued, in connection with any
of the following: (a) Common Stock or Common Stock Equivalents issued or
issuable in connection with any securities that are outstanding as at the
Issuance Date of the Series A Preferred Stock, (b) Common Stock or Common Stock
Equivalents issued or issuable under the Securities Purchase Agreement
(including the Series B Preferred Stock or Warrants); (c) Common Stock or Common
Stock Equivalents issued or issuance as “Performance Warrants”
(described in the Memorandum) and/or pursuant to an employee benefit plan,
approved by the Corporation’s board of directors, for directors, officers,
employees, advisors or consultants of the Corporation, (d) payment of interest
on any outstanding Notes or dividends on outstanding shares of Series A
Preferred Stock, (e) Common Stock or Common Stock Equivalents issued or issuable
in full or partial consideration in connection with a merger, consolidation or
purchase of substantially all of the securities or assets of a corporation or
other entity or (f) any warrants issued to the placement agent and its designees
for the transactions contemplated by the Securities Purchase

    For
purposes of this Section, the term “Conversion Price” shall mean initially

provisions of this Article VII shall have resulted in a change in such
Conversion Price prior to the occurrence of any event that would represent an
additional adjustment in such Conversion Price, as so adjusted.

    F.           Notice of
Adjustment.  Upon the occurrence of any event which requires
any adjustment of the Conversion Price, then, and in each such case, the
Corporation shall give notice thereof to the Holder of the Series A Preferred
Stock, which notice shall state the Conversion Price resulting from such
adjustment and the increase or decrease in the number of Conversion Shares
purchasable at such price upon exercise, setting forth in reasonable detail the
method of calculation and the facts upon which such calculation is
based.  Such calculation shall be certified by the Chief Financial
Officer of the Corporation.

     

    G.           Minimum Adjustment of
Conversion Price.  No adjustment of the Conversion Price shall
be made in an amount of less than 1% of the Conversion Price in effect at the
time such adjustment is otherwise required to be made, but any such lesser
adjustment shall be carried forward and shall be made at the time and together
with the next subsequent adjustment which, together with any adjustments so
carried forward, shall amount to not less than 1% of such Conversion
Price.

     

    H.           No Fractional
Shares.  No fractional shares of Common Stock are to be issued
upon the conversion of Series A Preferred Stock, but the Corporation shall pay a
cash adjustment in respect of any fractional share which would otherwise be
issuable in an amount equal to the same fraction of the average Market Price per
share of the Common Stock for the five (5) Trading Days immediately prior to the
date of such exercise.

     

    
      VIII.  VOTING
RIGHTS

Corporation.

     

    C.           Except
as set forth in Sections A and B of this Article VII, the Series A Preferred
Stock shall have no other voting rights or other rights to consent to any matter
to which stockholders of the Corporation may vote upon or consent
to.

     

    D.           The
provisions of Section C of this Article VII shall not be applicable if the
implementation thereof would cause the Corporation to be in violation of any
rule, regulation or policy of the National Association of Securities Dealers,
Inc. (“NASD”)
or the United States Securities and Exchange Commission.
