 5.
Representations and Warranties of Holder. Each Holder represents and warrants to the Corporation as follows: 
 (a)
Legal Capacity. Each Holder has full legal right, power and capacity to execute and deliver this Agreement and to perform his, her or its obligations hereunder. This Agreement constitutes the valid and legally binding obligation of Holder,

 
enforceable in accordance with its terms and conditions. Holder need not give any notice to, make any filing with, or obtain any authorization, consent, or approval of any third party or
Governmental Authority in order to consummate the transactions contemplated by this Agreement. Except as set forth on attached Schedule 4(a), no Person has any community property rights by virtue of marriage or otherwise in any of the Calando

Holder with respect to the execution and delivery of this Agreement and consummate the transactions contemplated by this Agreement. 
 (b) Title to Calando Securities. Holder is the lawful record and beneficial owner of the Calando Securities that will be transferred pursuant to Section 1 of this Agreement with good and marketable title thereto, and the Holder
has the right to sell, assign, convey, transfer and deliver the Calando Securities and any and all rights and benefits incident to the ownership thereof (including, without limitation, any registration or other rights pertaining to the Calando
Securities and the shares of common stock underlying such securities), all of which rights and benefits are transferable by the Holder to the Corporation pursuant to this Agreement, free and clear of all Claims. The exchange of the securities as
contemplated herein will (i) pass good and marketable title to all the Calando Securities transferred pursuant to Section 1 of this Agreement to the Corporation, free and clear of all Claims, and (ii) convey, free and clear of all
Claims, any and all rights and benefits incident to the ownership of such securities (including, without limitation, any registration or other rights pertaining to the securities and the shares of common stock underlying such securities).

 (c) Non-Contravention. Neither the execution and the delivery of this Agreement, nor the consummation of the
transactions contemplated hereby, will (i) violate any constitution, statute, regulation, rule, injunction, judgment, order, decree, ruling, charge, or other restriction of any Governmental Authority to which Holder is subject, or
(ii) conflict with, result in a breach of, constitute a default under, result in the acceleration of, create in any party the right to accelerate, terminate, modify, or cancel, or require any notice under any agreement, organizational document,
bylaws, partnership agreement, trust agreement, agreement any trust is bound by, contract, lease, license, instrument, or other arrangement to which Holder, as applicable, is a party or by which it is bound or to which any of its assets is subject.

 (d) Consents/Approvals. No consent, approval, authorization, order, registration or qualification of or with any
Governmental Authority or other entity or Person is required for the Exchange or the consummation by Holder of the transactions contemplated by this Agreement. 
 (e) Investment Representations. 
 (i) Holder qualifies as an
“accredited investor” (as defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”)) and is acquiring the Exchanged Securities hereunder for its own account and with

 
no intention of distributing or selling the Exchanged Securities except pursuant to a registration or an available exemption under applicable law. Holder understands that the Exchanged Securities
have not been (and are not being) registered under the Securities Act by reason of their contemplated issuance in transaction(s) exempt from the registration and prospectus delivery requirements of the Securities Act pursuant to Section 4(2)
thereof (including the rules and regulations promulgated thereunder), and that the reliance of the Corporation on such exemption from registration is predicated in part on the representations and warranties of Holder hereunder. 
 (ii) Holder agrees that it will not sell or otherwise dispose of any of the Exchanged Securities unless such sale or other
disposition has been registered or is exempt from registration under the Securities Act and has been registered or qualified or is exempt from registration or qualification under applicable securities laws of any State. 
 (iii) Holder understands that a restrictive legend consistent with the foregoing set forth in Section 10(a) of this
Agreement has been or will be placed on the certificates evidencing the Exchanged Securities to be issued to it hereunder, and related stop transfer instructions will be noted in the transfer records of the Corporation and/or its transfer agent for
the Exchanged Securities during the Prohibited Period. 
 (iv) Each Holder represents that it is not an Affiliate
(as defined herein) of the Corporation and will covenant and agree that if it becomes an Affiliate, it will promptly provide notice to the Corporation of such status and comply with insider trading laws and policies and the applicable “control
securities” provisions of Rule 144 in addition to any other obligations set forth in this Agreement. 
 (v)
Each Holder has such knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risk of an investment in the Exchanged Securities. Each Holder acknowledges that it has had access to all information
concerning the Corporation and Calando and their respective businesses, assets, liabilities, financial statements, and obligations which have been requested and has been provided the opportunity to ask questions of and receive answers from the
Corporation and/or Calando to fully and effectively evaluate the Exchange and the transactions contemplated herein. Each Holder understands that a new holding period for purposes of Rule 144 under the Securities Act will be triggered with respect to
the Exchanged Securities, and such Holder is able to bear the economic risk of loss of the investment in such Exchanged Securities and is able to afford a complete loss of such investment. 
 6. Termination. In the event the Closing Date does not occur on or before December 31, 2009, this Agreement may be terminated in
writing after such date (i) by the Corporation or (ii) by any Holder as to itself only (but not with respect to the other Holders) and withdraw all of such Holder’s portion of Calando Securities from the Exchange, upon two
(2) days prior written notice to the Corporation. 

 7. Indemnification. 
 (a) Each Holder understands and acknowledges that the Corporation is relying on representations, warranties, covenants and agreements made
by such Holder to the Corporation in this Agreement. Each Holder, as applicable, hereby agrees to indemnify, defend and hold harmless the Corporation, its Affiliates and their directors, officers, shareholders, principals, representatives, agents
and employees (each, a “Corporation Indemnified Party”), against any and all loss, damage, liability or expense (including, but not limited to, expenses related to the investigation and enforcement of any provisions of this
Agreement and/or any reasonable attorneys’ fees) (collectively, “Losses”) which any Corporation Indemnified Party may suffer, sustain or incur by reason of or in connection with or arising under (i) any inaccuracy or
breach of representation or warranty of such Holder contained in this Agreement; (ii) the breach of this Agreement or any covenant or agreement made by such Holder in this Agreement; or (iii) the sale or distribution by such Holder of the
Exchanged Securities in violation of this Agreement and/or the Securities Act or any other applicable law. This right to indemnification is in addition to any other remedy available to the Corporation under this Agreement. 
 (b) The Corporation understands and acknowledges that each Holder is relying on representations, warranties, covenants and agreements made
by the Corporation to such Holder in this Agreement. The Corporation hereby agrees to indemnify, defend and hold harmless each Holder and its officers, principals, Affiliates, trustees, agents and representatives, as applicable, (each, a
“Holder Indemnified Party”), against any and all Losses which any Holder Indemnified Party may suffer, sustain or incur by reason of or in connection with or arising under (i) any inaccuracy or breach of representation or
warranty of the Corporation contained in this Agreement; or (ii) the breach of this Agreement or any covenant or agreement made by the Corporation in this Agreement. This right to indemnification is in addition to any other remedy available to
