    STOCK
PURCHASE AGREEMENT

     

     

     

    THIS
STOCK PURCHASE AGREEMENT (“Agreement”) is made
and entered into by and between ZST Digital Networks, Inc. (“Company”), a Delaware
corporation, and John Chen, M.D. (“Participant”),
effective as of ____________________, 20___.  (Company and Participant
are sometimes referred to herein as “party” or
collectively as the “parties.”)  All
capitalized terms in this Agreement shall have the meaning assigned to them in
this Agreement or in the attached Appendix.

     

    


    RECITALS

    


    WHEREAS, the Company granted to
Participant an option to purchase Twenty-Five Thousand shares of Common Stock of
the Company pursuant to a Stock Option Agreement dated as of October [__], 2009;
and

    


    WHEREAS, Participant is hereby
exercising as described below the option pursuant to the terms of the Stock
Option Agreement.

    


    NOW, THEREFORE, it is hereby agreed as
follows:

    


    A.           PURCHASE
OF SHARES

     

    1.           Purchase.  Participant
hereby purchases ___________________ shares of Common Stock (the “Purchased Shares”)
pursuant to the provisions of the Option Agreement at the purchase price of
$_____________ per share (the “Purchase
Price”).

     

    2.           Payment.  Concurrently
with the delivery of this Agreement to the Company, Participant shall pay the
Purchase Price for the Purchased Shares in cash or cash equivalent and shall
deliver a duly-executed blank Assignment Separate from Certificate (in the form
attached hereto as Exhibit I) with
respect to the Purchased Shares.

     

    3.           Stockholder
Rights.  Until such time as the Company exercises the
Repurchase Right, Participant (or any successor in interest) shall have all
stockholder rights (including voting, dividend and liquidation rights) with
respect to the Purchased Shares, subject, however, to the transfer restrictions
of Articles B and C herein.

     

    B.           TRANSFER
RESTRICTIONS

     

    1.           Restriction
on Transfer.  Except for any Permitted Transfer, Participant
shall not transfer, assign, encumber or otherwise dispose of any of the
Purchased Shares which are subject to the Repurchase Right.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    


    2.           Transferee
Obligations.  Each person (other than the Company) to whom the
Purchased Shares are transferred by means of a Permitted Transfer must, as a
condition precedent to the validity of such transfer, acknowledge in writing to
the Company that such person is bound by the provisions of this Agreement and
that the transferred shares are subject to the Repurchase Right to the same
extent such shares would be so subject if retained by Participant.

     

    3.           Restrictive
Legends.  The stock certificates for the Purchased Shares shall
be endorsed with one or more of the following restrictive legend:

     

    “The
shares represented by this certificate are subject to certain repurchase rights
granted to the Corporation and accordingly may not be sold, assigned,
transferred, encumbered, or in any manner disposed of except in conformity with
the terms of a written agreement dated __________, 20___, between the
Corporation and the registered holder of the shares (or the predecessor in
interest to the shares).  A copy of such agreement is maintained at
the Corporation’s principal corporate offices.”

     

    


                          4.           Void Transfers.  The
Corporation shall not be required (i)
to transfer on its books any Purchased Shares which have been sold or
transferred in violation of the provisions of this Agreement or (ii) to treat as
the owner of the Purchased Shares, or otherwise to accord voting, dividend or
liquidation rights to, any transferee to whom the Purchased Shares have been
transferred in contravention of this Agreement.

    


    C.           REPURCHASE
RIGHT

     

    1.           Grant.  The
Company is hereby granted the right (the “Repurchase Right”),
exercisable at any time during the sixty (60)-day period following the date
Participant ceases for any reason to remain in Service (other than termination
by the Company without Cause or by Participant for Good Reason), to repurchase
at the Repurchase Price any or all of the Purchased Shares in which Participant
is not, at the time of his or her cessation of Service, vested in accordance
with the provisions of the Vesting Schedule set forth in Paragraph C.0 (such
shares to be hereinafter referred to as the “Unvested
Shares”).

     

    2.           Exercise
of the Repurchase Right.  The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period.  The
notice shall indicate the number of Unvested Shares to be repurchased, the
Repurchase Price to be paid per share and the date on which the repurchase is to
be effected, such date to be not more than thirty (30) days after the date of
such notice.  The certificates representing the Unvested Shares to be
repurchased shall be delivered to the Company on the closing date specified for
the repurchase.  Concurrently with the receipt of such stock
certificates, the Company shall pay to Owner, in cash or cash equivalents
(including the cancellation of any purchase-money indebtedness), an amount equal
to the Repurchase Price for the Unvested Shares which are to be repurchased from
Owner.

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    3.           Termination
of the Repurchase Right.

     

    (a)           The
Repurchase Right shall terminate with respect to any Unvested Shares for which
it is not timely exercised under Paragraph C.0.  In addition, the
Repurchase Right shall terminate and cease to be exercisable with respect to any
and all Purchased Shares in which Participant vests in accordance with the
following Vesting Schedule:

     

    (i)           Participant
shall vest in fifty percent (50%) of the Purchased Shares, and the Repurchase
Right shall concurrently lapse with respect to those Purchased Shares, upon
Participant’s completion of six (6) months of Service measured from October
[__], 2009.

     

    (ii)           Participant
shall vest in the remaining fifty percent (50%) of the Purchased Shares, and the
Repurchase Right shall concurrently lapse with respect to those Purchased
Shares, upon October [__], 2010.

     

    (b)           The
Repurchase Right shall automatically terminate in its entirety, and all the
Purchased Shares shall vest in full, immediately if Participant ceases to remain
in Service as a result of Participant’s termination of his employment for Good
Reason or the Company’s termination of Participant’s employment without
Cause.

     

    4.           Recapitalization.  Any
new, substituted or additional securities or other property (including cash paid
other than as a regular cash dividend) which is by reason of any
Recapitalization distributed with respect to the Purchased Shares shall be
immediately subject to the Repurchase Right and any escrow requirements
hereunder, but only to the extent the Purchased Shares are at the time covered
by such right or escrow requirements.  Appropriate adjustments to
reflect such distribution shall be made to the number and/or class of Purchased
Shares subject to this Agreement and to the Repurchase Price per share to be
paid upon the exercise of the Repurchase Right in order to reflect the effect of
any such Recapitalization upon the Company’s capital structure; provided, however,
that the aggregate Repurchase Price shall remain the same.

     

    D.           SPECIAL
TAX ELECTION

     

    1.           Section
83(b) Election.  Under Code Section 83, the excess of the Fair
Market Value of the Purchased Shares on the date any forfeiture restrictions
applicable to such shares lapse over the Purchase Price paid for those shares
will be reportable as ordinary income on the lapse date.  For this
purpose, the term “forfeiture restrictions” includes the right of the Company to
repurchase the Purchased Shares pursuant to the Repurchase
Right.  Participant may elect under Code Section 83(b) to be taxed at
the time the Purchased Shares are acquired, rather than when and as such
Purchased Shares cease to be subject to such forfeiture
restrictions.  Such election must be filed with the Internal Revenue
Service within thirty (30) days after the date of this
Agreement.  Even if the Fair Market Value of the Purchased Shares on
the date of this Agreement equals the Purchase Price paid (and thus no tax is
payable), the election must be made to avoid adverse tax consequences in the
future.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

     

    THE FORM FOR MAKING THIS ELECTION IS
ATTACHED AS EXHIBIT II HERETO.  PARTICIPANT UNDERSTANDS THAT FAILURE
TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN
THE RECOGNITION OF ORDINARY INCOME AS THE FORFEITURE RESTRICTIONS
LAPSE.

     

    2.           FILING
RESPONSIBILITY.  PARTICIPANT ACKNOWLEDGES
THAT IT IS PARTICIPANT’S SOLE RESPONSIBILITY, AND NOT THE COMPANY’S, TO FILE A
TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN IF PARTICIPANT REQUESTS THE
COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER
BEHALF.

     

    E.           GENERAL
PROVISIONS

     

    1.           Assignment.  The
Company may assign the Repurchase Right to any person or entity selected by the
Board, including (without limitation) one or more stockholders of the
Company.

     

    2.           Notices.  Any
notice required to be given under this Agreement shall be in writing and shall
be deemed effective upon personal delivery or upon deposit in the U.S. mail,
registered or certified, postage prepaid and properly addressed to the party
entitled to such notice at the address indicated below such party’s signature
line on this Agreement or at such other address as such party may designate by
ten (10) days advance written notice under this paragraph to all other parties
to this Agreement.

     

    3.           No
Waiver.  The failure of the Company in any instance to exercise
the Repurchase Right shall not constitute a waiver of any other repurchase
rights that may subsequently arise under the provisions of this Agreement or any
other agreement between the Company and Participant.  No waiver of any
breach or condition of this Agreement shall be deemed to be a waiver of any
other or subsequent breach or condition, whether of like or different
nature.

     

    4.           Cancellation
of Shares.  If the Company shall make available, at the time
and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement).  Such shares shall
be deemed purchased in accordance with the applicable provisions hereof, and the
Company shall be deemed the owner and holder of such shares, whether or not the
certificates therefor have been delivered as required by this
Agreement.

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

     

     

    F.           MISCELLANEOUS
PROVISIONS

     

    1.           Governing
Law.  This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware without resort to that
State’s conflict-of-laws rules.

     

    2.           Participant
Undertaking.  Participant hereby agrees to take whatever
additional action and execute whatever additional documents the Company may deem
necessary or advisable in order to carry out or effect one or more of the
obligations or restrictions imposed on either Participant or the Purchased
Shares pursuant to the provisions of this Agreement.

     

    3.           Agreement
is Entire Contract.  This Agreement constitutes the entire
contract between the parties hereto with regard to the subject matter
hereof.  This Agreement is made pursuant to the provisions of the
Employment Agreement and the Option Agreement and shall in all respects be
construed in conformity with the  terms of the Employment Agreement
and the Option Agreement.

     

    4.           Counterparts.  This
Agreement may be executed in counterparts, each of which shall be deemed to be
an original, but all of which together shall constitute one and the same
instrument.

     

    5.           Successors
and Assigns.  The provisions of this Agreement shall inure to
the benefit of, and be binding upon, the Company and its successors and assigns
and upon Participant, Participant’s assigns and the legal representatives, heirs
and legatees of Participant’s estate, whether or not any such person shall have
become a party to this Agreement and have agreed in writing to join herein and
be bound by the terms hereof.
