Re:

Shares of Common Stock of Trestle Holdings, Inc.

Dear Sirs/Madams:

In accordance with that certain Share Exchange Agreement, dated of even date herewith (the “Exchange Agreement”), by and among Trestle Holdings, Inc., a Delaware corporation (“Trestle”), MoqiZone Holdings Limited, a Cayman Islands corporation (the “Company”), Lawrence Cheung (“Cheung”), MKM Capital Opportunity Fund Ltd., a Cayman Islands corporation (“MKM”), and each of the shareholders of the Company set forth on the signature pages annexed thereto (the “Purchasers”), the undersigned (“Restricted Person”) hereby agrees that, for a period of twelve (12) months following the effective date of the registration statement registering all of the common stock underlying the preferred stock and warrants to be issued pursuant to the Share Exchange and the Offering, as such term is defined in the Exchange Agreement, for resale under the Securities Act of 1933, as amended (the “Lock-up Period”), the undersigned will not, directly or indirectly, without the prior written consent of MKM, which consent may be delayed, conditioned or withheld, at MKM’s sole discretion, offer for sale, sell, pledge, assign, hypothecate or otherwise create any interest in or dispose of (or enter into any transaction or device that is designed to, or could reasonably be expected to, result in any of the foregoing) any of the common stock, par value $0.001 per share, of Trestle (the “Common Stock”), or any security or other instrument which by its terms is convertible into, exercisable for, or exchangeable for shares of Common Stock, including, without limitation, the shares of Series B voting convertible preferred stock of Trestle (“Common Stock Equivalents”); provided, however, that no Restricted Person shall, during the twelve (12) months following the Lock-up Period, sell more than one-twelfth (1/12th) of their total holdings of Common Stock and Common Stock Equivalents during any one (1) month period.

The restrictions described in the immediately preceding paragraph do not apply to the following dispositions of Common Stock:

(a) The Restricted Person may transfer Common Stock to his or her spouse, siblings, parents or any natural or adopted children or other descendants or to any personal trust for the sole benefit of such family members and/or Restricted Person;

(b) Each Restricted Person may transfer Common Stock on his or her death to such Restricted Person’s estate, executor, administrator or personal representative or to such Restricted Person’s beneficiaries pursuant to a devise or bequest or by laws of descent and distribution;

(d) Each Restricted Person may make a bona fide pledge of Common Stock to a lender; and,

(e) Each Restricted Person may participate in any transaction in which all holders of the Common Stock of the Company participate or have the opportunity to participate pro rata, including, without limitation, a merger, consolidation or binding share exchange involving the Company, a disposition of the Common Stock in connection with the exercise of any rights, warrants or other securities distributed to the Company’s stockholders, or a tender or exchange offer for the Common Stock,

provided, however, that in the case of any transfer of Common Stock pursuant to clauses (a), (c), and (d), the transferor shall, at the request of the Company, provide evidence (which may include, without limitation, an opinion of counsel satisfactory in form, scope and substance to the Company in its sole discretion as the issuer thereof) satisfactory to the Company that the transfer is exempt from the registration requirements of the Securities Act, and such Common Stock shall remain subject to this Agreement and, as a condition of the validity of such disposition, the transferee shall be required to execute and deliver a counterpart of this Agreement. Thereafter, such transferee shall be deemed to be the Restricted Person for purposes of this Agreement.

Trestle and its agents, including its transfer agent, are authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

The undersigned’s obligations under this Lock-up Agreement shall be binding upon the undersigned’s successors, heirs, personal representatives and assigns, as the case may be.

The undersigned hereby warrants and represents that the undersigned has the full authority and capacity to enter into and carry out all the terms of this Lock-up Letter Agreement and is not subject to or bound by any agreement or instrument, or the order of any court or other governmental authority which in any way restricts the undersigned’s authority or capacity to enter into and carry out all the terms of this Lock-up Agreement.
