    CLASS
B COMMON STOCK PURCHASE WARRANT

    

    THIS CERTIFIES THAT, for value
received, _______________________________, or its registered assigns,
(the “Holder”) is
entitled to purchase from TRESTLE HOLDING, INC. (to be renamed
MoqiZone Holding Corporation), a Delaware corporation, (the “Company”), at any time or from
time to time during the period specified in Section 2 hereof,
_____________________ (  ), which represents that number of shares of
the Company’s common stock, $0.001 par value per share (the “Common Stock”), as shall be
equal to fifty percent (50%) of the number of shares of Common Stock that are
issuable upon conversion of the shares of Series A Preferred Stock of the
Company (the “Conversion
Shares”) to be received by the Holder in exchange for his or its Note
(ie. 2,778 Conversion Shares for each $10,000 principal amount of Note purchased
and $1,000 Stated Value of each share of Series A Preferred Stock received in
exchange for such Note), all pursuant to the terms and conditions of the “Securities Purchase Agreement”
(as hereinafter defined), at an exercise price of equal to (U.S.) $3.00 per share (the “Exercise Price”).

    

    As used
herein, the term “Class B
Warrant Shares” shall mean the shares of Common Stock that are
purchasable hereunder.  The number of Class B Warrant Shares and the
Exercise Price per Class B Warrant Share are subject to adjustment as provided
in Section 4 hereof.  The term “Class B Warrants” means this
Class B Warrant and the other Class B Warrants issued pursuant to that certain
Securities Purchase Agreement, dated as of June 1, 2009 (the “Securities Purchase
Agreement”), by and among the Company, the “MoqiZone Group,” the other
“Corporate Parties” (as defined therein), and the Investors listed on the
execution page thereof.

    

    Unless
otherwise defined in this Class B Warrant, all capitalized terms, when used
herein, shall have the same meaning as is defined in the Securities Purchase
Agreement.

    
      
         

      

      
        
        

        
          

        

      

      
         

      

    

    This
Class B Warrant is subject to the following terms, provisions, and
conditions:

    

    1.            Manner of
Exercise.

     

    Procedure.  Subject to the
provisions hereof, this Class B Warrant may be exercised by the Holder, in whole
or in part, by the surrender of this Class B Warrant, together with a completed
exercise agreement in the form attached hereto (the “Exercise Agreement”), to the
Company during normal business hours on any day that banks are generally open
for business in New York City (a “Business Day”) at the
Company’s principal executive offices (or such other office or agency of the
Company as it may designate by notice to the Holder), and upon payment to the
Company in cash, by certified or official bank check or by wire transfer for the
account of the Company of the Exercise Price for the Class B Warrant Shares
specified in the Exercise Agreement for the Class B Warrant Shares specified in
the Exercise Agreement; or by “cashless exercise” in accordance with the
provisions of sub-section (a) below, but only when a registration statement
under the Securities Act providing for the resale of the Warrant Stock is not
then in effect, or (iii) by a combination of the foregoing methods of payment
selected by the Holder of this Warrant.

     

    Shares shall have been registered for
resale pursuant to an effective registration statement.  The Class B
Warrant Shares so purchased shall be deemed to be issued to the Holder or such
Holder’s designee, as the record owner of such shares, as of the close of
business on the date on which the completed Exercise Agreement shall have been
delivered, and payment shall have been made for such shares as set forth
above.  Certificates for the Class B Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the Holder (without restrictive legend thereon when such
exercise occurs while a registration statement registering under the Securities
Act of 1933, as amended (the “Securities Act”) the resale of
the Class B Warrant Shares so purchased is effective or such Class B Warrant
Shares so purchased may be resold by the Holder pursuant to Rule 144 or any
similar successor rule) within a reasonable time, not exceeding three (3)
Business Days, after this Class B Warrant shall have been so
exercised.  The certificates so delivered shall be in such
denominations as may be requested by the Holder and shall be registered in the
name of the Holder or such other name as shall be designated by the
Holder.  If this Class B Warrant shall have been exercised only in
part, then, at the option of the Holder (i) the Holder may surrender this Class
B Warrant to the Company and, unless this Class B Warrant has expired, the
Company shall, at its expense, within a reasonable time, not exceeding three (3)
Business Days, after this Class B Warrant shall have been so exercised, deliver
to the Holder a new Class B Warrant representing the number of shares with
respect to which this Class B Warrant shall not then have been exercised, or
(ii) the Holder may retain this Class B Warrant and the Class B Warrant Shares
purchasable under this Class B Warrant shall be reduced by such number of Class
B Warrant Shares so exercised by the Holder and properly delivered by the
Company hereunder.

    a.           Cashless
Exercise

     

    Notwithstanding any provisions herein
to the contrary and commencing one (1) year following the Original Issue Date if
(1) the Per Share Market Value of one share of Common Stock is greater than the
Warrant Price (at the date of calculation as set forth below) and (ii) a
registration statement under the Securities Act providing for the resale of the
Warrant Stock is not then in effect by the date such registration statement is
required to be effective pursuant to the Registration Rights Agreement (as
defined in the Securities Purchase Agreement) or not effective at any time
during the Effectiveness Period (as defined in the Registration Rights
Agreement) in accordance with the terms of the Registration Rights Agreement,
unless the registration statement is not effective as a result of the Issuer
exercising its rights under Section 3(n) of the Registration Rights Agreement,
in lieu of exercising this Warrant by payment of cash, the Holder may exercise
this Warrant by a cashless exercise and shall receive the number of shares of
Common Stock equal to an amount (as determined below) by surrender of this
Warrant at the principal office of the Issuer together with the properly
endorsed Notice of Exercise in which event the Issuer shall issue to the Holder
a number of shares of Common Stock computed using the following
formula:

    

    
      
        
          
            	
                    X =

                  	
                    Y - (A)(Y)

                  
	 
      	
                    B

                  

          

        

      

    

    

    Where                  X
=           the number of
shares of Common Stock to be issued to the Holder.

     

    Y
=          the number of
shares of Common Stock purchasable upon exercise of all of the Warrant or, if
only a portion of the Warrant is being exercised, the portion of the Warrant
being exercised.

     

    A
=           the Warrant
Price.

     

    B
=           the Per Share
Market Value of one share of Common Stock.

     

    b.           Exercise
Limit.

    

    (i)           Notwithstanding
anything to the contrary set forth in this Class B Warrant, at no time may a
Holder of this Class B Warrant exercise their Class B Warrant if the number of
shares of Common Stock to be issued pursuant to such exercise 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 this Class B Warrant providing the Corporation with sixty-one (61)
day Waiver Notice that such Holder would like to waive this Section (b)(i) with
regard to any or all shares of Common Stock issuable upon exercise of this Class
B Warrant, this Section (b)(i) shall be of no force or effect with regard to
those shares of Common Stock referenced in the Waiver Notice; provided, further,
that during the sixty-one (61) day period prior to the expiration of the
Exercise Period, the Holder may waive this Section 1(b)(i) by providing a Waiver
Notice at any time during such sixty-one (61) day period; provided, further,
that any Waiver Notice provided during the sixty-one (61) day period prior to
the expiration of the Exercise Period will not be effective until the last day
of the Exercise Period.

    2.           Period of
Exercise.

     

    This Class B Warrant is exercisable,
commencing on or after the consummation of the Trestle Reverse Split and the
filing by Trestle with the Secretary of State of the State of Delaware of the
Certificate of Designations for the Series A Preferred Stock, and may be
exercised at any time or from time to time thereafter, until 6:00 p.m., New
York, New York time on May 31, 2012, when this Class B Warrant shall expire (the
“Exercise
Period”).

     

    3.           Certain
Agreements of the Company.  The
Company hereby covenants and agrees as follows:

    

    a.           Shares to
be Fully Paid.  All Class B
Warrant Shares will, upon issuance in accordance with the terms of this Class B
Warrant, be validly issued, fully paid, and non-assessable and free from all
taxes, liens, and charges with respect to the issue thereof.

     

    b.           Reservation
of Shares.  During the
Exercise Period, the Company shall at all times have authorized, and reserved
for the purpose of issuance upon exercise of this Class B Warrant, a sufficient
number of shares of Common Stock to provide for the exercise of this Class B
Warrant.

     

    c.           Listing.  If the Company’s
Common Stock is listed as of the date of this Class B Warrant, or if so listed
in the future, the Company shall maintain its listing of its Common Stock on
each national securities exchange or automated quotation system, as the case may
be, and shall maintain such listing of any other shares of capital stock of the
Company issuable upon the exercise of this Class B Warrant if and so long as any
shares of the same class shall be listed on such national securities exchange or
automated quotation system.

     

    d.           Certain
Actions Prohibited.  The Company will
not, by amendment of its charter or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities, or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed by it hereunder, but will at all
times in good faith assist in the carrying out of all the provisions of this
Class B Warrant and in the taking of all such action as may reasonably be
requested by the Holder of this Class B Warrant in order to protect the exercise
privilege of the Holder of this Class B Warrant against dilution or other
impairment, consistent with the tenor and purpose of this Class B
Warrant.  Without limiting the generality of the foregoing, the
Company (i) will not increase the par value of any shares of Common Stock
receivable upon the exercise of this Class B Warrant above the Exercise Price
then in effect, and (ii) will take all such actions as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock upon the exercise of this Class B
Warrant.

     

    e.           Successors
and Assigns.  This Class B
Warrant will be binding upon any entity succeeding to the Company by merger,
consolidation, or acquisition of all or substantially all the Company’s
assets.

    f.           Delivery
of Common Stock by Electronic Transfer.  In lieu of delivering
physical certificates representing the Common Stock issuable upon exercise,
provided the Company’s transfer agent is participating in the Depository Trust
Company (“DTC”) Fast
Automated Securities Transfer program and the Company has activated such
programs, upon request of the Holder and its compliance with the provisions
contained in Section 1, the Company shall use its best efforts to cause its
transfer agent to electronically transmit the Common Stock issuable upon
exercise to the Holder by crediting the account of Holder’s Prime Broker with
DTC through its Deposit Withdrawal Agent Commission system.

     

    4.           Antidilution
Provisions.  The Exercise
Price and the number of Class B Warrant Shares, as the case may be, shall be
subject to adjustment from time to time as provided in this Section 4; provided,
that the anti-dilution adjustments contemplated by Section 4e 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 Exercise Price as required herein results in a fraction of a cent, such
Exercise 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 Company shall effect any merger, reorganization,
restructuring, reverse stock split, consolidation, sale of all or substantially
all of the Company’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 Company whereby the Holder of this
Warrant, on the exercise hereof, at any time after the consummation of such
Fundamental Change, shall receive, in lieu of the Warrant 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 this Warrant, immediately prior thereto.

     

    If the Company 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, this Warrant 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 Company following the transfer of all or substantially
all of its properties or assets, the Company, 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 this
Warrant 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 this Warrant.

     

    c.           Continuation
of Terms.  Upon any
Fundamental Change or transfer (and any dissolution following any transfer)
referred to in this Article, this Warrant 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 this Warrant 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
Company, whether or not such person shall have expressly assumed the terms of
this Warrant as provided in Section 4(d). In the event this Warrant 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 Company’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).

    
      
         

      

      
        5

        
          

        

      

      
         

      

    

    d.           Extraordinary
Events Regarding Common Stock.  In the event that
the Company 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 Exercise Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Exercise 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 Exercise Price then in effect. The
Exercise Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described in this Section 4d. The number of
Warrant Shares that the Holder of this Warrant 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 Warrant 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 Exercise Price that would
otherwise (but for the provisions of this Section) be in effect, and (b) the
denominator is the Exercise Price in effect on the date of such
exercise.

     

    e.           Subsequent
Offerings.  If the Company
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 Fixed Exercise Price (as defined below) in effect on such date (the “Subsequent Offering Price”),
the Exercise Price shall be adjusted downward to a price determined by
multiplying the Exercise Price by the following quotient (expressed in decimal
form):

     

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

     

    ii.           the
sum of (y) the number of shares of the Company’s Common Stock then issued and
outstanding immediately prior to the issuance of such new securities and (z) 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 Exercise 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 date
of this Warrant, (b) Common Stock or Common Stock Equivalents issued or issuable
under the Securities Purchase Agreement (including this Warrant); (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 Company’s board of directors, for directors, officers,
employees, advisors or consultants of the Company, (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
Agreement.

    For
purposes of this Section, the term “Fixed Exercise Price” shall
mean initially $3.00, subject to adjustment in the event that any of the
anti-dilution provisions of this Section 4 shall have resulted in a change in
such Fixed Exercise Price prior to the occurrence of any event that would
represent an additional adjustment in such Fixed Exercise Price, as so
adjusted.

     

    f.           
Notice of
Adjustment.  Upon the
occurrence of any event which requires any adjustment of the Exercise Price,
then, and in each such case, the Company shall give notice thereof to the Holder
of this Class B Warrant, which notice shall state the Exercise Price resulting
from such adjustment and the increase or decrease in the number of Class B
Warrant 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 Company.

     

    g.           Minimum
Adjustment of Exercise Price.  No adjustment of
the Exercise Price shall be made in an amount of less than 1% of the Exercise
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
Exercise Price.

     

    h.           No
Fractional Shares.  No fractional
shares of Common Stock are to be issued upon the exercise of this Class B
Warrant, but the Company 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.

     

    i.           Certain
Definitions.

     

    i.           “Bloomberg” shall mean Bloomberg, L.P.
(or any successor to its function of reporting stock prices).

     

    ii.           “Market
Price” means, as
of any Trading Day, (i) the average of the last reported sale prices for the
shares of Common Stock on a national securities exchange which is the principal
trading market for the Common Stock for the five (5) Trading Days immediately
preceding such date as reported by Bloomberg or (ii) if no national securities
exchange is the principal trading market for the shares of Common Stock, the
average of the last reported sale prices on the principal trading market for the
Common Stock during the same period as reported by Bloomberg, or (iii) if market
value cannot be calculated as of such date on any of the foregoing bases, the
Market Price shall be the fair market value as reasonably determined in good
faith by (A) the Board of Directors of the Company, or (B) at the option of a
majority-in-interest of the holders of the outstanding Class B Warrants by an
independent investment bank of nationally recognized standing in the valuation
of businesses similar to the business of the Company.  The manner of
determining the Market Price of the Common Stock set forth in the foregoing
definition shall apply with respect to any other security in respect of which a
determination as to market value must be made hereunder.

    
      
         

      

      
        7

        
          

        

      

      
         

      

    
    

    iii.           “Common
Stock,” for
purposes of this Section 4, includes the Common Stock, without par value per
share, and any additional class of stock of the Company having no preference as
to dividends or distributions on liquidation, provided that the shares
purchasable pursuant to this Class B Warrant shall include only shares of Common
Stock, $0.001 par value per share, in respect of which this Class B Warrant is
exercisable, or shares resulting from any subdivision or combination of such
Common Stock, or in the case of any reorganization, reclassification,
consolidation, merger, or sale of the character referred to in Section 4(e)
hereof, the stock or other securities or property provided for in such
Section.

     

    iv.           “Trading
Day” shall mean any day on which the Common Stock is traded for any
period on the principal securities exchange or other securities market on which
the Common Stock is then being traded.

     

    5.           Issue
Tax.

     

    The
issuance of certificates for Class B Warrant Shares upon the exercise of this
Class B Warrant shall be made without charge to the Holder of this Class B
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the Holder of this Class B
Warrant.

    

    6.           No Rights
or Liabilities as a Stockholder.

     

    This
Class B Warrant shall not entitle the Holder to any voting rights or other
rights as a stockholder of the Company.  No provision of this Class B
Warrant, in the absence of affirmative action by the Holder to purchase Class B
Warrant Shares, and no mere enumeration herein of the rights or privileges of
the Holder, shall give rise to any liability of the Holder for the Exercise
Price or as a stockholder of the Company, whether such liability is asserted by
the Company or by creditors of the Company.

    

    7.           Transfer, Exchange, and
Replacement of Class B Warrant.

     

    a.           Restriction
on Transfer.  This Class B
Warrant and the rights granted to the Holder are transferable, in whole or in
part, upon surrender of this Class B Warrant, together with a properly executed
assignment in the form attached hereto, at the office or agency of the Company
referred to in Section 7(e) below, provided, however, that any
transfer or assignment shall be subject to the conditions set forth in Section
7(f) hereof and to the applicable provisions of the Securities Purchase
Agreement.  Until due presentment for registration of transfer on the
books of the Company, the Company may treat the registered holder hereof as the
owner and holder hereof for all purposes, and the Company shall not be affected
by any notice to the contrary.  Notwithstanding anything to the
contrary contained herein, the registration rights described in Section 8 are
assignable only in accordance with the provisions of the Registration Rights
Agreement.

     

    b.           Class B
Warrant Exchangeable for Different Denominations.  This Class B
Warrant is exchangeable, upon the surrender hereof by the Holder at the office
or agency of the Company referred to in Section 7(e) below, for new Class B
Warrants of like tenor representing in the aggregate the right to purchase the
number of shares of Common Stock, in not less than 1,000 increments, which may

    c.           Replacement
of Class B Warrant.  Upon receipt of
evidence reasonably satisfactory to the Company of the loss, theft, destruction,
or mutilation of this Class B Warrant and, in the case of any such loss, theft,
or destruction, upon delivery of an indemnity agreement reasonably satisfactory
in form and amount to the Company, or, in the case of any such mutilation, upon
surrender and cancellation of this Class B Warrant, the Company, at its expense,
will execute and deliver, in lieu thereof, a new Class B Warrant of like
tenor.

     

    d.           Cancellation;
Payment of Expenses.  Upon the
surrender of this Class B Warrant in connection with any transfer, exchange, or
replacement as provided in this Section 7, this Class B Warrant shall be
promptly canceled by the Company.  The Company shall pay all taxes
(other than securities transfer taxes) and all other expenses (other than legal
expenses, if any, incurred by the Holder) and charges payable in connection with
the preparation, execution, and delivery of Class B Warrants pursuant to this
Section 7.

     

    e.           Register.  The Company shall
maintain, at its principal executive offices (or such other office or agency of
the Company as it may designate by notice to the Holder), a register for this
Class B Warrant, in which the Company shall record the name and address of the
person in whose name this Class B Warrant has been issued, as well as the name
and address of each transferee and each prior owner of this Class B
Warrant.

     

    f.           Exercise
or Transfer Without Registration.  If, at the time
of the surrender of this Class B Warrant in connection with any exercise,
transfer, or exchange of this Class B Warrant, this Class B Warrant (or, in the
case of any exercise, the Class B Warrant Shares issuable hereunder), shall not
be registered under the Securities Act and under applicable state securities or
blue sky laws, the Company may require, as a condition of allowing such
exercise, transfer, or exchange, (i) that the Holder furnish to the Company a
written opinion of counsel, which opinion and counsel are acceptable to the
Company, to the effect that such exercise, transfer, or exchange may be made
without registration under the Securities Act and under applicable state
securities or blue sky laws, (ii) that the Holder execute and deliver to the
Company an investment letter in form and substance reasonably acceptable to the
Company and (iii) that the transferee be an “accredited investor” as defined in
Rule 501(a) promulgated under the Securities Act; provided, however, that no such
opinion, letter or status as an “accredited investor” shall be required in
connection with a transfer pursuant to Rule 144 under the Securities
Act.  The first Holder of this Class B Warrant, by taking and holding
the same, represents to the Company that such Holder is acquiring this Class B
Warrant for investment and not with a view to the distribution
thereof.

     

    8.           Registration
Rights.  The initial
Holder of this Class B Warrant (and certain assignees thereof) is entitled to
the benefit of such registration rights in respect of the Class B Warrant Shares
as are set forth in the Registration Rights Agreement dated as of June 1, 2009
by and among the Company and the investors listed on the execution page thereof
(the “Registration Rights

subject to redemption or call by the Company, unless consented to in writing by
the Holder of this Warrant.

and other communications required or permitted to be given or delivered
hereunder to the Holder of this Class B Warrant shall be in writing, and shall
be (i) personally delivered, (ii) be sent by certified or registered mail or by

first business day following such delivery (if delivered other than on a
business day during normal business hours where such notice is to be received),

Purchase Agreement, or at such other address as shall have been furnished to the
Company by notice from the Holder.  All notices, requests, and other

Company shall be address to ______________________________________, with a copy

Holder of this Class B Warrant by notice from the Company.  All
notices, requests, and other communications shall be deemed to have been given
either at the time of the receipt thereof by the person entitled to receive such
notice at the address of such person for purposes of this Section 10, or, if
mailed by registered or certified mail or with a recognized overnight mail
courier upon deposit with the United States Post Office or such overnight mail
courier, if postage is prepaid and the mailing is properly addressed, as the
case may be.

     

    11.          Governing
Law.  This Class B Warrant shall be enforced, governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made and to be performed entirely within such state, without regard
to the principles of conflict of laws.  The Company hereby submits to
the exclusive jurisdiction of the United States federal courts and New York
state courts located in New York, New York with respect to any dispute arising
under this Class B Warrant, the agreements entered into in connection herewith
or the transactions contemplated hereby or thereby.  The Company
irrevocably waives the defense of an inconvenient forum to the maintenance of
such suit or proceeding.  The Company further agrees that service of
process upon it mailed by first class mail shall be deemed in every respect
effective service of process upon the Company in any such suit or
proceeding.  Nothing herein shall affect the Holder’s right to serve
process in any other manner permitted by law.  A final non-appealable
judgment in any such suit or proceeding shall be conclusive and may be enforced
in other jurisdictions by suit on such judgment or in any other lawful
manner.

     

    12.          Miscellaneous.

     

    a.           Amendments.  This Class B
Warrant and any provision hereof may be amended by an instrument in writing
signed by the Company and holders of a majority of the then-unexercised Class B
Warrant Shares underlying the Class B Warrants issued pursuant to the Securities
Purchase Agreement.  All such amendments shall be binding to all
Holders of Class B Warrants issued pursuant to the Securities Purchase
Agreement.

    c.           Remedies.  The
Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Holder, by vitiating the intent and purpose of the
transaction contemplated hereby.  Accordingly, the Company
acknowledges that the remedy at law for a breach of its obligations under this
Class B Warrant will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Class B Warrant, that
the Holder shall be entitled, in addition to all other available remedies at law
or in equity, and in addition to the penalties assessable herein, to an
injunction or injunctions restraining, preventing or curing any breach of this
Class B Warrant and to enforce specifically the terms and provisions thereof,
without the necessity of showing economic loss and without any bond or other
security being required.

     

    d.           Facsimile
Signature. This Class B Warrant may be issued to the Holder containing a
facsimile signature of Lawrence Cheung, the Chief Executive Officer of the
Company; which facsimile signature the Company acknowledges and agrees shall

original signature.

(i) assignments separate from the Shares substantially in the form of Exhibit
A hereto, undated and appropriately endorsed in blank, with respect to
the Share comprising the Pledged Collateral and (ii) if legally required, such
financing statements as the Collateral Agent may reasonably request with respect
to the Pledged Collateral (or, if execution by Pledgors is not required pursuant
to the applicable Uniform Commercial Code, each of the Pledgors hereby
authorizes the Collateral Agent to file all financing statements deemed
necessary by the Investors to perfect the security interests granted hereunder),
(iii) take such other steps as the Investors may from time to time reasonably
request to perfect the Investors' security interest in the Pledged Collateral or
any part thereof under applicable law, and (iv) after the occurrence and during
the continuance of an Event of Default, to execute and deliver on behalf of the
Pledgors such other documents of transfer as the Investors or the Collateral
Agent may from time to time reasonably require to enable the Investors to
transfer the Pledged Collateral into the name of the Investors or the name of
its nominee (all of the foregoing are hereinafter collectively referred to as
the "Assignments").

    

    (c)           Notwithstanding anything to the
contrary, express or implied, contained in this Agreement or in the Guaranty,
upon consummation and performance of the Performance Obligations, the Notes
shall, for all purposes be deemed to have been fully paid and satisfied, and
this Agreement and the Guaranty shall automatically terminate and be of no
further force or effect.

     

    2.           Definition; Security for
Secured Obligations.

     

    (a)           Unless
otherwise defined in this Agreement, when used herein all capitalized terms
shall have the same meaning as is defined in the Purchase
Agreement.

     

    (b)           The
Pledged Collateral secures the prompt and complete payment, performance and
observance of the Notes and the Performance Obligations.

     

    3.           Pledged
Collateral Adjustments. If during
the term of this Agreement:

     

    (a)           any
non-cash dividend or distribution, reclassification, readjustment or other
change is declared or made in the capital structure of Company, or any option,
warrant or similar instrument included within the Pledged Collateral is
exercised, or both, or

     

    (b)           any
subscription, warrants, options shall be issued in connection with the Pledged
Collateral,

     

    
      
        
        

      

      
        - 2 -

        
          

        

      

      
        
        

      

    

     

    then the
Pledgors shall (i) promptly deliver new, substituted and additional shares,
warrants, options, or other equity securities, issued by reason of any of the
foregoing, and all certificates and other instruments evidencing the same to the
Investors to be held under the terms of this Agreement and shall constitute
Pledged Collateral hereunder, and (ii) promptly deliver to the Investors or the
Collateral Agent such additional Pledged Collateral.

    

    4.           Remedies Following an Event
of Default.

    

    Notwithstanding anything to the
contrary, express or implied, contained in this Agreement (including this
Section 4) or in the Purchase Agreement or any other Exhibit thereto (including
the Guaranty), an “Event of Default” that would otherwise permit the Secured
Parties to exercise any of their rights and remedies under this Agreement shall
not be deemed to have occurred if (i) the consummation of the Performance
Obligations shall be delayed beyond June 16, 2009, (ii) the Pledgors shall then
be responding to comments from the Securities and Exchange Commission and
otherwise seeking, in good faith, to perform such Performance Obligations, and
(iii) the outstanding principal amount of the Notes shall be increased as
provided in the Purchase Agreement.

    

    (a)           Following the occurrence and
during the continuance of an “Event of Default” (as that term is defined in the
Purchase Agreement), upon not less than twenty (20) days prior written notice to
the Pledgors and the Collateral Agent, Investors holding a majority in interest
of the outstanding principal amount of the Notes (the “Majority Investors”),
may, at their option, request that the Collateral Agent transfer or register the
Pledged Collateral or any part thereof into its or their nominee's name with or
without any indication that such Pledged Collateral is subject to the lien
created hereunder. In addition, upon the occurrence and during the continuance
of an Event of Default, the Investors may at any time exchange certificates or
other instruments representing or evidencing Pledged Collateral for certificates
or other instruments of smaller or larger denominations.

    

    (b)           If
at any time an Event of Default shall have occurred and be continuing, then, in
addition to having the right to exercise any right or remedy of a secured party
upon default under the New York State Uniform Commercial Code or applicable law
or at equity, Secured Parties may, to the extent permitted by law but subject at
all times to the terms of the Purchase Agreement, subject to giving notice to
Pledgor but without being required to take or do any action (except as provided
below):

    

    (i)           
apply any cash held by it hereunder to the payment of the Notes;
and

    

    (ii)           if
there shall be no such cash or if the cash so applied shall be insufficient to
pay in full the Notes, collect, receive, appropriate and realize upon the
Pledged Collateral or any part thereof, and/or sell, assign, transfer, contract
to sell or otherwise dispose of and deliver the Pledged Collateral or any part
thereof, in its entirety or in portions, at public or private sale or at any
broker's board, on any securities exchange or at any of Secured Parties places
of business or elsewhere, for cash, upon credit or for future delivery, and at
such price or prices as Secured Parties may deem best, and Secured Parties may
(except as otherwise provided by law) be the purchaser of any or all of the
Pledged Collateral so sold and thereafter may hold the same, absolutely, free
from any right or claim of whatsoever kind.

    

    (c)           In
the event of a sale as aforesaid, Secured Parties may, at any such sale,
restrict the number of prospective bidders or purchasers and/or further restrict
such prospective bidders or purchasers to Persons who will represent and agree
that they are purchasing for their own account, for investment and not with a
view to the distribution or resale of the Pledged Collateral, and may otherwise
require that such sale be conducted subject to restrictions as to such other
matters as Secured Parties may deem necessary in order that such sale may be
effected in such manner as to comply with all applicable state and federal
securities and other laws.  Upon any such sale, Secured Parties shall
have the right to deliver, assign and transfer the Pledged Collateral so sold to
the purchaser thereof.

     

    
      
        
        

      

      
        - 3 -

        
          

        

      

      
        
        

      

    

    

    (d)           Pledgors
hereby acknowledge that, notwithstanding that a higher price might be obtained
for the Pledged Collateral at a public sale than at a private sale or sales, the
making of a public sale of the Pledged Collateral may be subject to registration
requirements under applicable securities laws and other legal restrictions,
compliance with which would make a public sale of the Pledged Collateral
impractical.  Accordingly, Pledgors hereby agree that private sales
made by Secured Parties in good faith in accordance with the provisions of this
Section 4 may be at prices
and on other terms less favorable to the seller than if the Pledged Collateral
were sold at a public sale, and that Secured Parties shall not have any
obligation to take any steps in order to permit the Pledged Collateral to be
sold at a public sale.

    

    (e)           Each
purchaser at any such sale shall hold the property sold, absolutely free from
any claim or right whatsoever, including any equity or right of redemption of
Pledgors, and Pledgors hereby specifically waive all rights of redemption, stay
or appraisal and other rights that Pledgors has or may have under any law,
regulation or statute now existing or hereafter adopted or
otherwise.  Secured Parties shall give Pledgors not less than thirty
(30) calendar days' written notice of its intention to make any such public or
private sale.  Such notice, in case of a public sale, shall state the
time and place fixed for such sale, and, in case of a sale at broker's board, on
a securities exchange, at one or more of Secured Parties' places of business or
elsewhere, shall state the board, exchange or other location at which such sale
is to be made and the day on which the Pledged Collateral, or that portion
thereof so being sold, will first be offered for sale at such
location.  Such notice, in case of a private sale, shall state only
the date on or after which such sale may be made.  Any such notice
given as aforesaid shall be deemed to be reasonable notification.

    

    (f)           Any
such public sale shall be held at such time or times within ordinary business
hours and at such place or places as Secured Parties may fix in the notice of
such sale.  At any sale the Pledged Collateral may be sold in one lot
as an entirety or in parts, as Secured Parties may determine.  Secured
Parties shall not be obligated to make any sale pursuant to any such
notice.  Secured Parties may, without notice or publication, adjourn
any sale or cause the same to be adjourned from time to time by announcement at
the time and place fixed for the sale, and such sale may be made at any time or
place to which the same may be so adjourned.  In case of any sale of
all or any part of the Pledged Collateral on credit or for future delivery, the
Pledged Collateral so sold may be retained by Secured Parties until the selling
price is paid by the purchaser thereof, but Secured Parties shall not incur any
liability in case of the failure of such purchaser to take up and pay for the
Pledged Collateral so sold and, in case of any such failure, such Pledged
Collateral may again be sold upon like notice.

    

    (g)           On
any sale of any part of the Pledged Collateral, Secured Parties is hereby
authorized to comply with any limitation or restriction in connection with such
sale that may be necessary in order to avoid any violation of applicable law or
in order to obtain any required approval of the purchaser(s) by any governmental
authority or officer or court.

    

    (h)           Pledgors
hereby acknowledge, understand and agree that compliance with the foregoing
procedures shall satisfy any applicable requirements that such sale or
disposition be made in a commercially reasonable manner.

    

    5.           Representations
and Warranties. The
Pledgors hereby represent and warrant to the Investors as follows:

    

    (a)           the
Pledgors are the legal and beneficial owner of the Pledged Collateral owned by
the Pledgors, free and clear of any lien, except for the lien created by this
Agreement; and

     

    
      
        
        

      

      
        - 4 -

        
          

        

      

      
        
        

      

    

     

    (b)           The
Pledgors have full power and authority to enter into this Agreement, assign,
deposit, pledge and grant a lien on or otherwise transfer all of its rights in
the Pledged Collateral free and clear of any liens;

    

    6.            Voting
Rights. During
the term of this Agreement, and except as otherwise provided in this Section 6,
the Pledgors shall have the right to vote any Shares which form all or a portion
of the Pledged Collateral, to the extent such Shares may be voted, on all
questions presented to the holders of ordinary shares of Trestle, and the
Collateral Agent will deliver all necessary documents to allow the Pledgors to
take such action upon the Pledgors' request. After the occurrence and during the
continuance of an Event of Default, the Investors may, at the Investors' option,
exercise all voting and other consensual rights and powers pertaining to the
Pledged Collateral (to the extent it may vote). the Pledgors hereby agree to
execute all proxies or other instruments, documents or agreements deemed
reasonably necessary by the Investors to evidence the right to vote the Pledged
Collateral as provided hereunder, and the Pledgors agree that they shall not be
entitled to rescind, revoke or otherwise modify the Investors' vote executed in
accordance with this Section 6. Any and all proxies executed by the Pledgors
pursuant to this Section 6 shall be deemed for all purposes to be a proxy
coupled with an interest and shall be irrevocable until the payment in full, in
cash, of all amounts due under the Note.

     

    7.           Dividends
and Other Distributions.  The Collateral Agent shall be entitled to
receive any and all dividends and other distributions paid in respect of the
Pledged Collateral which dividends and/or distributions shall be deemed to be
held in escrow if received by the Investors and shall become part of the Pledged
Collateral upon receipt thereof.

     

    8.           Transfers
and Other Liens. The
Pledgors agree that, except as otherwise provided in Section 4 above, until all
of the Obligations are paid in full, it will not (i)
sell or otherwise dispose of, or grant any option or other rights with
respect to, any of the Pledged Collateral without the prior written consent of
the Investors, or (ii) create or permit to exist any lien upon or with respect
to any of the Pledged Collateral, except for the lien created by this
Agreement.

     

    9.            Sale
of Pledged Collateral.  Subject at all times to the provisions
of Section 10 below, in
view of the fact that federal and state securities laws may impose
certain restrictions on the method by which a sale of the Pledged Collateral may
be effected after an Event of Default, the Pledgors agrees that after the
occurrence and during the continuance of an Event of Default, the Investors may,
from time to time, attempt to sell all or any part of the Pledged Collateral by
means 0f a private
placement restricting the bidders and prospective purchasers to those who are
qualified and will represent and agree that they are purchasing for investment
only and not for distribution. In so doing, the Investors may solicit offers to
buy the Pledged Collateral, or any part of it, from one or more investors deemed
by the Investors, in its reasonable judgment, to be financially responsible
parties who might be interested in purchasing the Pledged Collateral. The
acceptance by the Investors of the highest and best offer obtained therefrom
shall be deemed to be a commercially reasonable method of disposing of such
Pledged Collateral

    

    10.          Alternative
Remedy. Notwithstanding the provisions of this Agreement, on and after an
Event of Default, the Investors may (but shall not be obligated to) elect, in
lieu of the remedies specified in Section 10, to retain all of the Pledged
Collateral as full and complete liquidated damages for any amounts then due and
owing by the Pledgors to the Investors under the Note.

    

    11.          Termination.  This
Agreement shall remain in full force and effect until the Note
shall have been indefeasibly paid in full. Upon the termination of this
Agreement as provided above (other than as a result of the sale of the Pledged
Collateral), this Agreement shall automatically terminate and all liens and
security interests created hereunder shall terminate and be
released.  Upon confirmation of payment in full of the Note, the
Collateral Agent shall (a) if any UCC-1 Financing Statements were previously
filed, file any UCC-3 Termination Statements releasing the lien and security
interest created by the Assignments, and (b) to the extent it then has
possession of any of the remaining Pledged Collateral, will deliver such Pledged
Collateral and the Assignments to the Pledgors.

    12.          Agreements
with and Duties of the Collateral Agent.

    

    (a)           The
Collateral Agent shall be under no duty to give the Pledged Collateral held by
it hereunder any greater degree of care than it gives its own similar
property.

    

    (b)           If
the Collateral Agent is permitted or required to deliver any of the Pledged
Collateral or pay money back to any Business Party or Business Parties, such
payment shall be made by check or by wire transfer, at the Collateral Agent's
sole discretion, unless the Collateral Agent shall have received written notice
from such Business Party or Business Parties of a new and/or different postal
address or unless this Agreement shall have provided otherwise.  If
payment is made by check or Pledged Collateral is to be delivered, the same
shall be mailed to the address specified by the Business Party(s) in this
Agreement (or to a new or different address subsequently specified to Collateral
Agent by writing from such Business Party(s)).

     

    (c)           Whenever
authorization shall be provided by the terms of this Agreement for the payment
or delivery of Pledged Collateral by the Collateral Agent to one or more
Business Parties and there is no express requirement hereunder for written
instructions from the applicable Business Party(s) before such delivery is made,
the Collateral Agent shall notify all Business Parties and, in its sole
discretion, may defer payment or defer return or delivery of Pledged Collateral
until such written requirement or consent is received from all of the Business
Parties (or, depending on the Collateral Agent’s requirements, from less than
all of them).  Where Collateral Agent determines to so defer payment
or delivery, the Collateral Agent shall give written notice to the Business
Parties of such determination.

    

    (e)           It
is expressly understood and agreed that under no circumstances shall the
Collateral Agent be required to pay or have paid to any Business Party(s) any
sum not representing proceeds from the sale of any Pledged Collateral that may
be delivered to the Collateral Agent.

     

    (f)           It
is intended that the duties and responsibilities of the Collateral Agent shall
be limited to ministerial duties and responsibilities to the maximum extent
permitted by law.  In keeping with that intent, it is agreed that the
receipt by Collateral Agent of Exhibit
B, or an alternative written instrument containing the substantive
information or content that is in Exhibit
B (whether or not also including other information and content not
inconsistent with the request and approval of delivery or disbursement action
proposed to be taken by the Collateral Agent) shall, in the absence of actual
knowledge by the Collateral Agent of falsehood, fraud or other intentional or
gross misconduct on the part of any of the Business Parties that would render
the proposed action under the written instrument to be inappropriate, be full
and sufficient justification and authorization for the proposed payment or
disbursement action by the Collateral Agent.  Notwithstanding anything to the
contrary, express or implied, contained in this Agreement, if the Collateral
Agent shall receive written instructions from the Investors in accordance with
Alternative Instructions 2 of Exhibit
B (or words of similar
import), the Collateral Agent shall: (i) furnish a copy of such instructions to
the Pledgors at the address designated on Exhibit
B (or any alternative
address requested by the Pledgors in writing), and (ii) take no action with
respect to such written request until a date which shall be not less than ten
(10) Business Days following receipt of such written instructions from the
Investors.

     

    (g)           The
ministerial reliance by Collateral Agent on the written instrument referred to
in Section
12(f) shall be full and sufficient justification and authorization, as
stated in such Section, notwithstanding a determination that Collateral Agent
had certain specified discretionary inquiry powers and opportunities that
Collateral Agent did not pursue or that, absent the provisions of Section 12(f) above,
Collateral Agent had (or might have had) fiduciary responsibilities to
investigate before making any such payment or disbursement and did not do
so.

    (h)           The
Collateral Agent shall have no duty or responsibility to enforce collection of
any check delivered to it and subsequently dishonored, nor shall Collateral
Agent have any duty or responsibility to give notice to any Business Party of
such attempted payment and the subsequent dishonor thereof.

     

    (i)           The
Collateral 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 (including copies of signature pages), instrument or
other document (in each case, whether a copy, facsimile or original) which is
given to the Collateral Agent pursuant to this Agreement, without the Collateral
Agent being obligated to undertake any action or investigation to verify the
truth or accuracy thereof — unless the Collateral Agent has
actual knowledge that the document or other document, instruction, certificate
or signature is not accurate, truthful, authorized or
genuine.  For purposes of this Section 12(i),
“Actual knowledge, or any other instance where “knowledge” would be required
(and, therefore, “actual knowledge” would be required as a standard of
“knowledge”)  shall consist of actual and conscious apprehension and
understanding, presently in the mind or consciousness of the person acting for
Collateral Agent (as opposed to knowledge previously known but not currently
remembered or consciously being thought about) and shall be limited to such
“actual knowledge” by an attorney in Collateral Agent’s firm who is currently
actively engaged in the management of the Collateral Agent and who is made aware
of the document, etc. that is the subject of this Section
12(i).  For purposes of this Agreement “knowledge” (being
required to be “actual knowledge”) shall not included knowledge of any other
attorney or person in LHTT who is not directly involved in making decisions
regarding, or managing, the LHTT activities as Collateral
Agent.  Knowledge by others within LHTT shall not be imputed to the
persons described above for purposes of determining whether “knowledge” or
“actual knowledge” existed.   Persons (lawyers) at Collateral
Agent as to whom “actual knowledge” is relevant under this Section 12(i)
currently includes Louis E. Taubman and Rachael Schmierer.

     

    (j)          The
Collateral Agent may consult with and act relative hereto upon advice of counsel
of its own selection in reference to any matter connected herewith, and shall
not be liable to any of the parties hereto, or their respective legal
representatives, heirs, successors and assigns, for any action taken in good
faith on the advice of counsel or for any mistake of fact or error of judgment,
or for any acts or omissions of any kind taken or made in good faith unless
caused by its willful misconduct or gross negligence.

     

    (k)           The
Collateral Agent shall not be responsible for, or have any duty to inquire into,
or be required to enforce any of the terms and provisions of any document or
agreement other than this Agreement.

     

    (l)           Without
limiting the foregoing, the Collateral Agent shall not be responsible for, or
have any duty to inquire into, monitor or enforce obligations between any of the
Business Parties as to (i) whether there was support or justification for any
such Business Party to act in accordance with written instructions of such
Business Party or any other Business Party in attached Exhibit
B or any written alternative acceptable to Collateral Agent that included
(with anything else) the material or content of Exhibit
B, or (ii) whether any Business Party properly uses and applies funds
received by it, whether from the Collateral Agent or third parties, in
accordance with the provisions of this Agreement or other applicable
documents.  Notwithstanding anything to the
contrary, express or implied, contained in this Agreement, if the Collateral
Agent shall receive written instructions from the Investors in accordance with
Alternative Instructions 2 of Exhibit
B (or words of similar
import), the Collateral Agent shall: (i) furnish a copy of such instructions to
the Pledgors at the address designated on Exhibit
B (or any alternative
address requested by the Pledgors in writing), and (ii) take no action with
respect to such written request until a date which shall be not less than ten
(10) Business Days following receipt of such written instructions from the
Investors.

    (m)          This
Agreement sets forth exclusively the duties of the Collateral Agent with respect
to any and all matters pertinent hereto and no implied duties or obligations
shall be read into this Agreement against the Collateral Agent.

     

    (n)           If
the Collateral Agent shall be uncertain as to its duties or rights hereunder or
if it receives instructions with respect to the Pledged Collateral or any funds
that may be derived from the sale or transfer of any Pledged Collateral, which,
in the Collateral Agent’s sole discretion, it determines to be in actual or
potential conflict with this Agreement or other instructions that it has
received, the Collateral Agent shall be excused from taking action that it might
otherwise be required to take, and its sole obligation shall be to keep safely
all property held in escrow until the uncertainty is resolved.  Such
uncertainty can be resolved by written and signed agreement among all affected
Business Parties and Investors or by order or judgment of a court of competent
jurisdiction, naming the involved Business Parties as participants in the action
or proceeding brought to obtain judicial determination of the involved uncertain
duties and obligations.

     

    Alternatively,
the Collateral Agent may, in its discretion, seek judicial determination of any
dispute or uncertainty and/or deposit all of the Pledged Collateral and any
funds that may be derived from the sale or transfer of any Pledged Collateral,
in Court pursuant to proceedings under New York law.

     

    (p)           The
Collateral Agent makes no representation as to the validity, value, genuineness
or collectability of any portion or all of the Pledged Collateral held by or
delivered to it.

     

    (q)           In
the event that:

     

    (i)           the
Collateral Agent shall receive any conflicting or inconsistent notices or
instructions from any one or more of the Business Parties, or

     

    (ii)          there
shall be any disagreement between or among any of the Business Parties,
resulting in adverse claims or demands being made in connection with the subject
matter of this Agreement, or

     

    (iii)         there
shall be any disagreement between or among any of the Business Parties and any
other person, resulting in adverse claims or demands being made in connection
with the subject matter of this Agreement, or

     

    (iv)         the
Collateral Agent, in good faith, shall be in doubt as to what action it should
take hereunder,

     

    then, and
in any such event, Collateral Agent may, at its option, refuse to comply with
any notices, instructions, claims or demands on it, or refuse to take any other
action hereunder, so long as such disagreement continues or such doubt exists,
and in any such event, the Collateral Agent shall not become liable in any way
or to any person for its failure or refusal to act.  The Collateral
Agent shall be entitled to continue so to refrain from acting until (A) the
rights of all Business Parties or other third person(s) shall have been fully
and finally adjudicated by a court of competent jurisdiction or (B) all
differences shall have been adjusted and all doubt resolved by agreement among
all of the interested persons, and the Collateral Agent shall have been notified
thereof in writing signed by all such persons.  The Collateral Agent
shall have the option, after thirty (30) days’ notice to the Business Parties of
its intention to do so, to file an action in interpleader requiring the parties
to answer and litigate any claims and rights among themselves.

     

    The
rights of the Collateral Agent under this Section 12(q) are

    (r)           The
Collateral Agent does not have and will not have any interest in the Pledged
Collateral or any funds that may be derived from the sale or transfer of any
Pledged Collateral, but is serving only as escrow holder and has only possession
thereof.

     

    (s)           The
Collateral Agent’s duties and responsibilities shall be determined only with
reference to this Agreement.  The Collateral Agent is not charged with
any duties or responsibilities in connection with any other document or
agreement.

     

    (t)           The
Collateral Agent may execute any of its powers or responsibilities hereunder
either directly or by or through its agents or attorneys and the Collateral
Agent shall not be responsible for any misconduct or negligence on the part of
any agent or attorney appointed with due care by it hereunder.

     

    (u)           Each
of Business Parties do hereby release the Collateral Agent from any act done or
omitted to be done by the Collateral Agent in good faith in the performance of
its duties hereunder, and each of Business Parties do hereby jointly and
severally agree to fully indemnify the Collateral Agent and its directors,
officers, employees and agents (the “Collateral Agent Indemnified
Parties”) for, and to hold each of them harmless from and against, any
loss, liability, claim, damage or expense (including reasonable attorneys’ fees
and expenses) incurred by the Collateral Agent Indemnified Parties, arising out
of or in connection with the Collateral Agent entering into this Agreement and
carrying out its duties hereunder, including the reasonable costs and expenses
of defending itself from any claim or liability; provided,
however, that the Collateral Agent Indemnified Parties shall not be
entitled to indemnification hereunder for losses, liabilities and expenses
caused by the willful misconduct, fraud or gross negligence of any of the
Collateral Agent Indemnified Parties.  The agreements contained in
this Section
12(u) shall survive despite any termination of this Agreement or the
resignation or removal of the Collateral Agent.

     

    (v)           The
Collateral Agent shall not incur any liability for not performing any act or
fulfilling any duty, obligation or responsibility hereunder by reason of any
occurrence beyond the control of the Collateral Agent (including but not limited
to any act or provision of any present or future law or regulation or
governmental authority, any act of God or war, or the unavailability of the
Federal Reserve Bank wire or telex or other wire or communication
facility).

     

    (w)           Anything
in this Agreement to the contrary notwithstanding, in no event shall the
Collateral Agent be liable for consequential loss or damage of any kind
whatsoever (including but not limited to lost profits), regardless of the form
of action.

     

    (x)           The
Collateral Agent may resign at any time or be removed by the written mutual
consent of the Business Parties.  No resignation or removal of the
Collateral Agent and no appointment of a successor Collateral Agent, however,
shall be effective until the acceptance or removal of the Collateral Agent in
the manner herein provided.  In the event of the resignation or
removal of the Collateral Agent, the Business Parties shall in good faith agree
upon a successor Collateral Agent.  If the Business Parties are unable
to agree upon a successor Collateral Agent within fourteen (14) days after
receipt of a notice of resignation or removal is given, the Collateral Agent may
deposit the Pledged Collateral and any funds delivered to the Collateral Agent
from the sale or transfer of any Pledged Collateral with a court of competent
jurisdiction and may petition, at the sole expense of the Business Parties, a
court of competent jurisdiction for the appointment of a successor Collateral
Agent.  Any successor Collateral Agent shall execute and deliver to
the predecessor Collateral Agent and the Business Parties an instrument
accepting such appointment and the transfer of the Pledged Collateral and any
funds delivered to the Collateral Agent from the sale or transfer of any Pledged
Collateral and agreeing to the terms of this Agreement, and thereupon such
successor Collateral Agent shall, without further act, become vested with all
the estates, properties, rights, powers and duties of the predecessor Collateral
Agent as if originally named herein.

     

    (y)           Any
law firm with which the Collateral Agent may merge or consolidate shall be the
successor Collateral Agent without further act.

    (z)           At
any time either the Pledgors or the Investors can request the Collateral Agent
to resign, the Collateral Agent agrees to resign and another Collateral Agent
acceptable to both the Pledgors and the Investors shall be appointed as
Collateral Agent.
