ARTICLE I

THE MERGER

1.1 The Merger. At the Effective Time (as defined in Section 1.2) and subject to and upon the terms and conditions of this Agreement and the applicable provisions of the DGCL, Merger Sub shall be merged with and into SG Blocks, the separate corporate existence of Merger Sub shall cease and SG Blocks shall continue as the surviving corporation in the Merger (the “Surviving Subsidiary”).

1.2 Effective Time; Closing. Subject to the conditions of this Agreement, as soon as practicable on or after the Closing Date (as hereinafter defined), the parties hereto shall cause the Merger to be consummated by filing a Certificate of Merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware in accordance with the applicable provisions of the DGCL (the time of such filing, or such later time as may be agreed in writing by SG Blocks and CDSI and specified in the Certificate of Merger being the “Effective Time” and the date of such filing being the “Effective Date”). Unless this Agreement shall have been terminated pursuant to Section 8.1, the consummation of the transactions contemplated by this Agreement (the “Closing”), other than the filing of the Certificate of Merger, shall take place at the offices of Xxxxxxxx Xxxxxx, counsel to CDSI, 000 Xxxxxxxxx Xxxxxx, 00xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000 at a time and date to be specified by the parties, which shall be no later than the fifth (5th) business day after the satisfaction or waiver of the conditions set forth in Article VI, or at such other time, date and location as the parties hereto agree in writing (the “Closing Date”). Closing signatures may be transmitted by facsimile or by emailed PDF file.

1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of the DGCL and Applicable Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of Merger Sub shall vest in the Surviving Subsidiary, and all debts, liabilities and duties of Merger Sub shall become the debts, liabilities and duties of the Surviving Subsidiary, and SG Blocks shall continue as a wholly owned subsidiary of CDSI.

1.4 Governing Documents. At the Effective Time,

(a) the Certificate of Incorporation of CDSI shall be amended and restated in the form attached hereto as Exhibit A;

(b) the Certificate of Incorporation of Merger Sub in the form attached hereto as Exhibit B shall become the certificate of incorporation of the Surviving Subsidiary, except that Article I shall state that the name of the Surviving Subsidiary shall be “SG Building Blocks, Inc.”; and

1.5 Effect on SG Blocks Securities. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and this Agreement and without any action on the part of SG Blocks or the holders of any of the securities of SG Blocks, the following shall occur:

(a) Conversion of SG Blocks Common Stock and Derivative Securities; Issuance to CDSI. At the Effective Time, all of the issued and outstanding shares of the common stock, par value $0.001, of SG Blocks (“SG Blocks Common Stock”) issued and outstanding immediately prior to the Effective Time, will automatically be canceled and extinguished and be converted, collectively, into the right to receive an aggregate of 36,050,741 shares of common stock, par value $0.01 per share, of CDSI (“CDSI Common Stock”) (the “Stock Consideration”); with each such share of SG Blocks Common Stock converted into the right to receive a pro rata portion of the Stock Consideration. Immediately following the conversion contemplated by this Section 1.5(a), 100 shares of SG Blocks Common Stock, as the Surviving Subsidiary, shall be issued to CDSI.

(b) Adjustments to Exchange Ratios. The numbers of shares of CDSI Common Stock that the security holders of SG Blocks are entitled to receive as a result of the Merger shall be equitably adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into shares of CDSI Common Stock), extraordinary cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to CDSI Common Stock occurring on or after the date hereof and prior to the Effective Time.

(c) Conversion of SG Blocks Warrants. Subject to adjustment in accordance with Section 1.5(b), the warrants (“SG Blocks Warrants”) to purchase shares of SG Blocks Common Stock issued and outstanding immediately prior to the Effective Time shall be automatically converted into warrants (“CDSI Warrants”) to purchase 1,145,509 shares of CDSI Common Stock having terms and conditions substantially identical in all material respects to the terms and conditions pertaining to the SG Blocks Warrants. Upon consummation of the Merger, the CDSI Warrants shall be issued upon surrender of the SG Blocks Warrants.

(d) No Fractional Shares. No fraction of a share of CDSI Common Stock will be issued by virtue of the Merger or the transactions contemplated hereby, and each security holder of SG Blocks who would otherwise be entitled to a fraction of a share of CDSI Common Stock (after aggregating all fractional shares of CDSI Common Stock that otherwise would be received by such holder) shall be deemed to receive from CDSI, in lieu of such fractional share, one (1) share of CDSI Common Stock.

(e) Capital Stock of Merger Sub. All issued and outstanding shares of the capital stock of Merger Sub shall automatically, and without any action on the part of the holder thereof, be converted into an aggregate of 100 validly issued, fully paid and non-assessable shares of common stock of the Surviving Subsidiary to be issued to CDSI pursuant to Section 1.5(a).

1.6 Surrender of Certificates.

(a) Exchange Agent. American Stock Transfer and Trust Company shall be designated by the parties hereto to act as the exchange agent (the “Exchange Agent”) in the Merger.

(b) Procedure. Subject to Section 1.14 below, certificates representing the shares of CDSI Common Stock shall be issued to the holders of SG Blocks Common Stock upon surrender of the certificates or instruments representing all of the outstanding shares of SG Blocks Common Stock (collectively, “SG Blocks Certificates”) as provided for herein. Promptly after the Effective Time, and in no event more than three (3) business days thereafter, CDSI shall cause the Exchange Agent to mail to each holder of record (as of the Effective Time) of SG Blocks Certificates: (i) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the SG Blocks Certificates shall pass, only upon delivery of the SG Blocks Certificates to the Exchange Agent and shall contain such other customary provisions as CDSI may reasonably specify), and (ii) instructions for use in effecting the surrender of the SG Blocks Certificates in exchange for the shares of CDSI Common Stock to which the holder of such SG Blocks Certificates is entitled as a result of the Merger (and any dividends or other distributions pursuant to Section 1.5(b)). Upon surrender of the SG Blocks Certificates for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by CDSI, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holders of such SG Blocks Certificates shall be entitled to receive in exchange therefor such certificates representing the number of shares of CDSI Common Stock, less the applicable Escrow Shares (defined below), for which their shares of SG Blocks Common Stock are exchangeable at the Effective Time and any dividends or distributions payable pursuant to Section 1.5(b), and the SG Blocks Certificates so surrendered shall forthwith be canceled. Until so surrendered, outstanding SG Blocks Certificates will be deemed, from and after the Effective Time, to evidence only the right to receive the applicable shares of CDSI Common Stock issuable pursuant to Section 1.5(a).

(c) Distributions With Respect to Unexchanged Shares. No dividends or other distributions declared or made after the date of this Agreement with respect to shares of CDSI Common Stock with a record date after the Effective Time will be paid to the holders of any unsurrendered SG Blocks Certificates with respect to the shares of CDSI Common Stock to be issued upon surrender thereof until the holders of record of such SG Blocks Certificates shall surrender such SG Blocks Certificates. Subject to applicable law, following surrender of any such SG Blocks Certificates with a properly completed letter of transmittal, the Exchange Agent shall promptly deliver to the record holders thereof, without interest, the certificates representing shares of CDSI Common Stock issued in exchange therefor and the amount of any such dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such shares of CDSI Common Stock.

(d) Transfers of Ownership. If certificates representing the shares of CDSI Common Stock are to be issued in a name other than that in which the SG Blocks Certificates surrendered in exchange therefor are registered, it will be a condition of the issuance thereof that the SG Blocks Certificates so surrendered will be properly endorsed and otherwise in proper form for transfer and that the persons requesting such exchange will have paid to CDSI or any agent designated by it any transfer or other taxes required by reason of the issuance of certificates representing the shares of CDSI Common Stock in any name other than that of the registered holder of the SG Blocks Certificates surrendered, or established to the satisfaction of CDSI or any agent designated by it that such tax has been paid or is not payable.

(e) Termination of Exchange Agent Obligations. Shares of CDSI Common Stock held by the Exchange Agent that have not been delivered to holders of SG Blocks Certificates within six months after the Effective Time shall promptly be delivered to CDSI, and thereafter holders of SG Blocks Certificates who have not theretofore complied with the exchange procedures outlined in and contemplated by this Section 1.6 shall thereafter look only to CDSI (subject to abandoned property, escheat and similar laws) for their claim for shares of CDSI Common Stock and any dividends or distributions pursuant to Section 1.5(b) with respect to shares of CDSI Common Stock to which they are entitled.

(f) No Liability. Notwithstanding anything to the contrary in this Section 1.6, neither the Exchange Agent, CDSI, the Surviving Subsidiary, SG Blocks nor any party hereto shall be liable to a holder of shares of SG Blocks Common Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

1.7 No Further Ownership Rights in SG Blocks Stock. All CDSI Common Stock deemed issued to security holders of SG Blocks upon consummation of the Merger and conversion of the SG Blocks Common Stock shall be deemed to have been issued in full satisfaction of all rights pertaining to the corresponding outstanding SG Blocks Common Stock and there shall be no further registration of transfers on the records of the Surviving Subsidiary of the SG Blocks Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, SG Blocks Certificates are presented to CDSI for any reason, they shall be canceled and exchanged as provided in this Article I.

1.8 Tax Consequences. It is intended by the parties hereto that the Merger shall constitute a tax-free reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (“Code”). The parties hereto adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Income Tax Regulations.

1.9 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest CDSI with full right, title and possession to all assets, property, rights, privileges, powers and franchises of SG Blocks and the Surviving Subsidiary, the then current officers and directors of SG Blocks, and the officers and directors of CDSI shall take all such lawful and necessary action.

1.10 Escrow. As the sole remedy for the indemnification obligations set forth in Article VII of this Agreement, an aggregate of 817,500 shares of CDSI Common Stock to be received by the holders of SG Blocks Common Stock, allocated pro rata amongst such holders, representing 2% of the shares of CDSI Common Stock to be outstanding immediately after the Closing Date, shall be deposited into escrow (the “Escrow Shares), in accordance with the terms and conditions of the escrow agreement to be entered into at the Closing between CDSI, the Committee (defined below), the Representative (defined below) and Continental Stock Transfer & Trust Company (“CST&T”), as escrow agent (“Escrow Agent”), in form and substance mutually and reasonably agreed to by CDSI and SG Blocks and providing for the terms contemplated by Article VII hereof (the “Escrow Agreement”). The Escrow Agreement shall provide that, on the 5th business day after CDSI has filed with the SEC its Annual Report on Form 10-K for the fiscal year ending December 31, 2011 (the “Escrow Release Date”), the Escrow Agent shall release the Escrow Shares, less that portion thereof applied in satisfaction of or reserved with respect to indemnification claims in connection with claims made pursuant to Section 7.1(a) of this Agreement (“Escrow Claims”). Any Escrow Shares due to be released on the Escrow Release Date that continue to be held with respect to any unresolved Escrow Claim shall be delivered to the stockholders of SG Blocks in the same proportions as originally deposited into escrow, promptly upon such resolution, subject to reduction, if any, for the indemnification obligation associated with such resolved Escrow Claim.

1.11 Committee and Representative for Purposes of Escrow Agreement.

(a) CDSI Committee. Prior to the Closing, the Board of Directors of CDSI shall appoint a committee consisting of one or more of its then members to act on behalf of CDSI to take all necessary actions and make all decisions pursuant to the Escrow Agreement. In the event of a vacancy in such committee, the remaining members of the committee (if any) shall appoint as a successor a Person who was a director of CDSI prior to the Closing Date or some other Person who would qualify as an “independent” director of CDSI and who has not had any relationship with SG Blocks or the stockholders of SG Blocks prior to the Closing. If no members of the committee remain at the time of such vacancy, the board of directors of CDSI shall appoint as a successor a Person who was a director of CDSI prior to the Closing Date or some other Person who would qualify as an “independent” director of CDSI and who has not had any relationship with SG Blocks or the stockholders of SG Blocks prior to the Closing. Such committee is intended to be the “Committee” referred to in Article VII hereof and the Escrow Agreement.

(b) Representative. SG Blocks and the Signing Stockholders hereby designate Xxxx Xxxxxx to represent the interests of the Persons entitled to receive CDSI Common Stock as a result of the Merger for purposes of the Escrow Agreement. If such Person ceases to serve in such capacity, for any reason, such Person shall designate his or her successor. Failing such designation within ten (10) business days after the Representative has ceased to serve, those members of the Board of Directors of CDSI who were directors of SG Blocks prior to the Closing shall appoint as successor a Person who was a former stockholder of SG Blocks or such other Person as such members shall designate. Such Persons or their successors are intended to be the “Representative” referred to in Article VII hereof and the Escrow Agreement.

1.12 Signing Stockholder Matters.

(a) By his, her or its execution of this Agreement, each Signing Stockholder, in his, her or its capacity as a stockholder of SG Blocks, hereby approves and adopts this Agreement and authorizes SG Blocks and its directors and officers to take all actions necessary for the consummation of the Merger and the other transactions contemplated hereby pursuant to the terms of this Agreement and its exhibits. Such execution shall be deemed to be action taken by the irrevocable written consent of each Signing Stockholder for purposes of the relevant provisions of the DGCL and other Applicable Law.

(b) Each Signing Stockholder for himself, herself or itself only, represents and warrants as follows:

(i) he, she or it has had both the opportunity to ask questions and receive answers from the officers and directors of CDSI and all persons acting on CDSI’s behalf concerning the business and operations of CDSI and to obtain any additional information to the extent CDSI possesses or may possess such information or can acquire it without unreasonable effort or expense necessary to verify the accuracy of such information;

(ii) he, she or it has had access to the CDSI SEC Reports (defined below) filed prior to the date of this Agreement;

(iii) that the execution and delivery of this Agreement by such Signing Stockholder does not, and the performance of his, her or its obligations hereunder will not, require any consent, approval, authorization or permit of, or filing with or notification to, any Governmental Entity (as defined), except (1) for applicable requirements, if any, of the Securities Act of 1933, as amended (“Securities Act”), the Securities Exchange Act of 1934, as amended (“Exchange Act”), state securities laws (“Blue Sky Laws”), and the rules and regulations thereunder, and (2) where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings or notifications, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect (as defined in Section 10.2(a)) on such Signing Stockholder or SG Blocks or, after the Closing, CDSI, or prevent consummation of the Merger or otherwise prevent the parties hereto from performing their obligations under this Agreement;

(iv) that he, she or it owns the shares of SG Blocks Common Stock listed on Schedule 1.12(b)(iv) as being owned by him, her or it free and clear of all Liens, except as set forth in Schedule 1.12(b)(iv).

(c) Each Signing Stockholder that is an entity, for itself, represents, warrants and acknowledges, with respect to each holder of its equity interests, to the same effect as the foregoing provisions of Section 1.10(b).

1.13 Lock Up Agreements. Simultaneously with the execution of this Agreement, each person or entity listed on Schedule 1.13, representing all of the officers and directors of SG Blocks and each stockholder of SG Blocks currently owning in excess of 20% of the SG Blocks Common Stock, are executing and delivering to CDSI agreements (“Lock Up Agreements”) in the form of Exhibit C hereto.

1.14 Shares Subject to Appraisal Rights.

(a) Notwithstanding Section 1.5 hereof, Dissenting Shares (as defined in Section 1.14(b)) shall not be converted into a right to receive shares of CDSI Common Stock. The holders thereof shall be entitled only to such rights as are granted by the DGCL. Each holder of Dissenting Shares who becomes entitled to payment for such shares pursuant to the DGCL shall receive payment therefor from CDSI in accordance with the DGCL, provided, however, that (i) if any stockholder of SG Blocks who asserts appraisal rights in connection with the Merger (a “Dissenter”) shall have failed to establish his entitlement to such rights as provided in the DGCL, or (ii) if any such Dissenter shall have effectively withdrawn his demand for payment for such shares or waived or lost his right to payment for his shares under the appraisal rights process under the DGCL, the shares of SG Blocks Common Stock held by such Dissenter shall be treated as if they had been converted, as of the Effective Time, into a right to receive the shares of CDSI Common Stock as provided in Section 1.5. SG Blocks shall give CDSI prompt notice of any demands for payment received by SG Blocks from a person asserting appraisal rights, and CDSI shall have the right to participate in all negotiations and proceedings with respect to such demands. SG Blocks shall not, except with the prior written consent of CDSI, make any payment with respect to, or settle or offer to settle, any such demands or negotiate or enter into any agreement with respect thereto.

(b) As used herein, “Dissenting Shares” means any shares of SG Blocks Common Stock held by Persons who are entitled to appraisal rights under the DGCL, and who have properly exercised, perfected and not subsequently withdrawn or lost or waived their rights to demand payment with respect to those shares in accordance with the DGCL.

1.15 Investment Representation. All shares of CDSI Common Stock issued in accordance with the terms hereof shall, when issued, be restricted shares and may not be sold, transferred or otherwise disposed of by the holders thereof without registration under the Securities Act or an available exemption from registration under the Securities Act. The certificates representing the shares of CDSI Common Stock issued in accordance with the terms hereof will contain the appropriate restrictive legends, and CDSI shall issue appropriate stop-transfer instructions to the CDSI transfer agent with respect to such shares of CDSI Common Stock. Prior to the Closing, each holder of record (as of the Effective Time) of SG Blocks Certificates, which immediately prior to the Effective Time represented outstanding shares of SG Blocks Common Stock whose shares were converted into the right to receive shares of CDSI Common Stock pursuant to Section 1.5, shall provide an investment representation letter (the “Representation Letters”) in the form attached hereto as Exhibit D.

To the best of SG Blocks’ knowledge, except as set forth on Schedule 2.31, no Related Party is, directly or indirectly, interested in any SG Blocks Contract with SG Blocks (other than such contracts as relate to any such person’s ownership of capital stock or other securities of SG Blocks or such person’s employment with SG Blocks).

ARTICLE VII

INDEMNIFICATION

7.1 Indemnification of CDSI.

(a) Subject to the terms and conditions of this Article VII (including without limitation the limitations set forth in Section 7.4), CDSI and its representatives, successors and permitted assigns (the “CDSI Indemnitees”) shall be indemnified, defended and held harmless with respect to the matters under Sections 7.1(a)(i) and 7.1(a)(ii), below, but only to the extent of the Escrow Shares, from and against all Losses asserted against, resulting to, imposed upon, or incurred by any CDSI Indemnitee by reason of, arising out of or resulting from:

(i) the inaccuracy or breach of any representation or warranty of SG Blocks or any of the Signing Stockholders contained in or made pursuant to this Agreement, any Schedule or any certificate delivered by SG Blocks to CDSI pursuant to this Agreement with respect hereto or thereto in connection with the Closing; and

(ii) the non-fulfillment or breach of any covenant or agreement of SG Blocks or any of the Signing Stockholders contained in this Agreement.

(b) As used in this Article VII, the term “Losses”, subject to Section 7.4(e) hereof, shall include all actual losses, liabilities, damages, judgments, awards, orders, penalties, settlements, costs and expenses (including, without limitation, interest, penalties, court costs and reasonable out-of-pocket legal fees and expenses) including those arising from any demands, claims, suits, actions, costs of investigation, notices of violation or noncompliance, causes of action, proceedings and assessments whether or not made by third parties or whether or not ultimately determined to be valid. Solely for the purpose of determining the amount of any Losses (and not for determining any breach) for which the CDSI Indemnitees may be entitled to indemnification pursuant to Article VII, any representation or warranty contained in this Agreement that is qualified by a term or terms such as “material,” “materially,” or “Material Adverse Effect” shall be deemed made or given without such qualification and without giving effect to such words.

7.2 Indemnification of Third Party Claims. The indemnification obligations and liabilities under this Article VII with respect to actions, proceedings, lawsuits, investigations, demands or other claims brought against a CDSI Indemnitee by a Person other than SG Blocks or a Signing Stockholder (a “Third Party Claim”) shall be subject to the following terms and conditions:

(a) Notice of Claim. CDSI, acting through the Committee, will give the Representative prompt written notice after receiving written notice of any Third Party Claim or discovering the liability, obligation or facts giving rise to such Third Party Claim (a “Notice of Claim”) which Notice of Third Party Claim shall set forth (i) a brief description of the nature of the Third Party Claim, (ii) the total amount of the actual out-of-pocket Loss or the anticipated potential Loss (including any costs or expenses which have been or may be reasonably incurred in connection therewith), and (iii) whether such Loss may be covered (in whole or in part) under any insurance and the estimated amount of such Loss which may be covered under such insurance, and the Representative shall be entitled to participate in the defense of Third Party Claim at its expense.

(b) Defense. The Representative shall have the right, at its option (subject to the limitations set forth in subsection 7.2(c) below) and at the Company’s expense, by written notice to CDSI, to assume the entire control of, subject to the right of CDSI to participate (at its expense and with counsel of its choice) in, the defense, compromise or settlement of the Third Party Claim as to which such Notice of Claim has been given, and shall be entitled to appoint a recognized and reputable counsel reasonably acceptable to CDSI to be the lead counsel in connection with such defense. If the Representative is permitted and elects to assume the defense of a Third Party Claim:

(i) the Representative shall diligently and in good faith defend such Third Party Claim and shall keep the Committee reasonably informed of the status of such defense; provided, however, that the Committee shall have the right to approve any settlement, which approval will not be unreasonably withheld, delayed or conditioned except to the extent the settlement relates solely to monetary damages that are indemnified fully under Section 7.1; and

(ii) CDSI and the Committee shall cooperate fully in all respects with the Representative in any such defense, compromise or settlement thereof, including, without limitation, the selection of counsel, and CDSI and the Committee shall make available to the Representative all pertinent information and documents under its control.

(c) Limitations of Right to Assume Defense. The Representative shall not be entitled to assume control of such defense and, subject to the limitations of Section 7.4, shall pay the reasonable fees and expenses of one counsel retained by CDSI or the Committee if (i) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation; (ii) the Third Party Claim seeks an injunction or equitable relief against a CDSI Indemnitee; or (iii) there is a reasonable probability that a Third Party Claim may materially and adversely affect CDSI or its subsidiaries other than as a result of money damages or other money payments.

(d) Other Limitations. Failure to give prompt Notice of Claim or to provide copies of relevant available documents or to furnish relevant available data shall not constitute a defense (in whole or in part) to any Third Party Claim by a CDSI Indemnitee against the Representative and shall not affect the Representative’s duty or obligations under this Article VII, except to the extent (and only to the extent that) such failure shall have adversely affected the ability of the Representative to defend against or reduce its liability or caused or increased such liability or otherwise caused the damages for which the Representative is obligated to be greater than such damages would have been had the Committee given the Representative prompt notice hereunder. So long as the Representative is defending any such action actively and in good faith, CDSI shall not settle such action. CDSI shall make available to the Representative all relevant records and other relevant materials required by them and in the possession or under the control of CDSI, for the use of the Representative and its representatives in defending any such action, and shall in other respects give reasonable cooperation in such defense.

(e) Failure to Defend. If the Representative, promptly after receiving a Notice of Claim, fails to defend such Third Party Claim actively and in good faith, CDSI or the Committee, subject to the limitations of Section 7.4, will (upon further written notice) have the right to undertake the defense, compromise or settlement of such Third Party Claim as it may determine in its reasonable discretion, provided that the Representative shall have the right to approve any settlement, which approval will not be unreasonably withheld, delayed or conditioned.

(f) CDSI Indemnitee Rights. Anything in this Section 7.2 to the contrary notwithstanding, the Representative shall not, without the written consent of the Committee, settle or compromise any action or consent to the entry of any judgment which does not include as an unconditional term thereof the giving by the claimant or the plaintiff to each of the CDSI Indemnitees of a full and unconditional release from all liability and obligation in respect of such action without any payment by any CDSI Indemnitee.

(g) Representative Consent. Unless the Representative has consented to a settlement of a Third Party Claim, the amount of the settlement shall not be a binding determination of the amount of the Loss and such amount shall be determined in accordance with the provisions of the Escrow Agreement.

7.3 Insurance and Tax Effect.

(a) To the extent that any Losses that are subject to indemnification pursuant to this Article VII are covered by insurance, CDSI shall use reasonable best efforts to obtain the maximum recovery under such insurance; provided that CDSI Indemnitees shall nevertheless be entitled to bring a claim for indemnification under this Article VII in respect of such Losses and the time limitations set forth in Section 7.4 hereof for bringing a claim of indemnification under this Agreement shall be tolled during the pendency of such insurance claim. The existence of a claim by CDSI for monies from an insurer or against a third party in respect of any Loss shall not, however, delay any payment pursuant to the indemnification provisions contained herein and otherwise determined to be due and owing by the Representative. If CDSI has received the payment required by this Agreement from the Representative in respect of any Loss and later receives proceeds from insurance or other amounts in respect of such Loss, then it shall hold such proceeds or other amounts in trust for the benefit of the Representative and shall pay to the Representative, as promptly as practicable after receipt, a sum equal to the amount of such proceeds or other amount received, up to the aggregate amount of any payments received from the Representative pursuant to this Agreement in respect of such Loss. Notwithstanding any other provisions of this Agreement, it is the intention of the parties that no insurer or any other third party shall be (i) entitled to a benefit it would not be entitled to receive in the absence of the foregoing indemnification provisions, or (ii) relieved of the responsibility to pay any claims for which it is obligated.

(b) To the extent that any Losses that are subject to indemnification pursuant to this Article VII are deductible for income tax purposes by CDSI, SG Blocks or the Merger Sub, as the case may be, the amount of any Loss shall be reduced by the income tax savings to such party as a result of the payment of such Loss.

7.4 Limitations on Indemnification.

(a) Survival; Time Limitation. The representations, warranties, covenants and agreements in this Agreement or in any writing delivered by SG Blocks or the Signing Stockholders to CDSI in connection with this Agreement (including the certificate required to be delivered by SG Blocks pursuant to Section 6.3(a)) shall survive the Closing until the Escrow Release Date (the “Survival Period”).

(b) Any indemnification claim made by CDSI or Merger Sub in writing prior to the termination of the Survival Period shall be preserved despite the subsequent termination of the Survival Period and any claim set forth in a Notice of Claim sent prior to the expiration of such Survival Period shall survive until final resolution thereof. Except as set forth in the immediately preceding sentence, (i) no claim for indemnification under this Article VII shall be brought after the end of the Survival Period, and (ii) the indemnification rights of CDSI Indemnitees under this Article VII shall terminate and be of no further force or effect.

(c) Deductible. No amount shall be payable under Article VII unless and until the aggregate amount of all indemnifiable Losses otherwise payable exceeds $500,000 (the “Deductible”), in which event the amount payable shall be only the amount in excess of the Deductible.

(d) Aggregate Amount Limitation. The aggregate liability for Losses pursuant to Section 7.1 shall not in any event exceed the Escrow Shares and no CDSI Indemnitee shall have any claim against SG Blocks’ stockholders other than the Escrow Shares during the Escrow Period.

(e) No Special or Consequential Damages. In no event shall Losses be deemed to include any special, indirect, consequential or punitive damages.

7.5 Exclusive Remedy. CDSI on behalf of itself and the other CDSI Indemnitees, hereby acknowledges and agrees that, from and after the Closing, the sole remedy of the CDSI Indemnitees with respect to any and all claims for money damages arising out of or relating to this Agreement shall be pursuant and subject to the requirements of the indemnification provisions set forth in this Article VII. Notwithstanding any of the foregoing, nothing contained in this Article VII shall in any way impair, modify or otherwise limit a CDSI Indemnitees’ right to bring any claim, demand or suit against the other party based upon such other party’s actual fraud.

7.6 Adjustment to Purchase Price. Amounts paid for indemnification under Article VII shall be deemed to be an adjustment to the “purchase price” paid to the stockholders of SG Blocks in connection with business combination between SG Blocks and CDSI, except as otherwise required by Law.

7.7 Representative Capacities; Application of Escrow Shares. The parties acknowledge that the Representative’s obligations under this Article VII are solely as a representative of the stockholders of SG Blocks in the manner set forth in the Escrow Agreement with respect to the obligations to indemnify the CDSI Indemnitees under this Article VII and that the Representative shall have no personal responsibility for any expenses incurred by him in such capacity and that all payments to the CDSI Indemnitees as a result of such indemnification obligations shall be made solely from, and to the extent of, the Escrow Shares. Out-of-pocket expenses of the Representative for attorneys’ fees and other costs shall be borne in the first instance by CDSI, which may make a claim for reimbursement thereof against the Escrow Shares upon the claim with respect to which such expenses are incurred becoming an Established Claim (as defined in the Escrow Agreement). The parties further acknowledge that all actions to be taken by the CDSI Indemnitees pursuant to this Article VII shall be taken on their behalf by the Committee in accordance with the provisions of the Escrow Agreement. The Escrow Agent, pursuant to the Escrow Agreement after the Closing, may apply all or a portion of the Escrow Shares to satisfy any claim for indemnification pursuant to this Article VII. The Escrow Agent will hold the remaining portion of the Escrow Shares until final resolution of all claims for indemnification or disputes relating thereto. Notwithstanding anything to the contrary contained herein, all Escrow Shares remaining in escrow following the Final Escrow Release Date in excess of the Escrow Shares necessary to satisfy any timely filed claim for indemnification shall be released and delivered to the Persons entitled to them on such date. Notwithstanding anything to the contrary contained herein, the Representative shall have no liability to SG Blocks or any Stockholder or any party hereto for any action taken or omitted to be taken hereunder, unless such liability is determined by a judgment or a court of competent jurisdiction to have resulted from the gross negligence, or willful misconduct of the Representative. CDSI shall defend, indemnify and hold harmless the Representative for all losses, damages, costs and expenses (including reasonable attorney’s fees and costs of investigation) arising out of or in connection with, the performance by the Representative of its duties and obligations under this Agreement, unless such liability is determined by a judgment or a court of competent jurisdiction to have resulted from the gross negligence, or willful misconduct of the Representative.

8.3 Fees and Expenses.

Delivery by facsimile or electronic transmission to counsel for the other party of a counterpart executed by a party shall be deemed to meet the requirements of the previous sentence.

10.4 Entire Agreement; Third Party Beneficiaries. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the Exhibits and Schedules hereto (a) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, it being understood that the letter of intent between CDSI and SG Blocks executed on or about March 21, 2011 is hereby terminated in its entirety and shall be of no further force and effect (except to the extent expressly stated to survive the execution of this Agreement and the consummation of the transactions contemplated hereby); and (b) are not intended to confer upon any other person any rights or remedies hereunder (except as specifically provided in this Agreement).

10.5 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

10.6 Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

10.7 Governing Law. This Agreement shall be governed by and construed in accordance with the internal law of the State of Delaware regardless of the law that might otherwise govern under applicable principles of conflicts of law thereof.

10.8 Arbitration. Any disputes or claims arising under or in connection with this Agreement or the transactions contemplated hereunder shall be resolved by binding arbitration. Notice of a demand to arbitrate a dispute by either party shall be given in writing to the other at their last known address. Arbitration shall be commenced by the filing by a party of an arbitration demand with the American Arbitration Association (“AAA”). The arbitration and resolution of the dispute shall be resolved by a single arbitrator appointed by the AAA pursuant to AAA rules. The arbitration shall in all respects be governed and conducted by applicable AAA rules, and any award and/or decision shall be conclusive and binding on the parties. The arbitration shall be conducted in New York City, New York. The arbitrator shall supply a written opinion supporting any award, and judgment may be entered on the award in any court of competent jurisdiction. Each party shall pay its own fees and expenses for the arbitration, except that any costs and charges imposed by the AAA and any fees of the arbitrator for his services shall be assessed against the losing party by the arbitrator. In the event that preliminary or permanent injunctive relief is necessary or desirable in order to prevent a party from acting contrary to this Agreement or to prevent irreparable harm prior to a confirmation of an arbitration award, then either party is authorized and entitled to commence a lawsuit solely to obtain equitable relief against the other pending the completion of the arbitration in a court having jurisdiction over the parties. Each party hereby consents to the exclusive jurisdiction of the federal and state courts located in the State of Delaware, New Castle County, for such purpose.

10.9 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

10.10 Assignment. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other parties. Subject to the first sentence of this Section 10.10, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

10.11 Amendment. This Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed on behalf of each of the parties.

10.12 Extension; Waiver. At any time prior to the Closing, any party hereto may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto and (iii) waive compliance with any of the agreements or conditions for the benefit of such party contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Delay in exercising any right under this Agreement shall not constitute a waiver of such right.

10.13 Currency. All references to currency amounts in this Agreement shall mean United States dollars.

10.14 Schedules. The information furnished in the Schedules is arranged in sections corresponding to the Sections of this Agreement, and the disclosures in any section of the Schedules shall qualify (a) the corresponding Section of this Agreement and (b) other Sections of this Agreement to the extent (notwithstanding the absence of a specific cross-reference), that it is clear from a reasonable reading of the Schedules and such other Sections of this Agreement that such disclosure is also applicable to such other Sections of this Agreement. The Schedules and the information and disclosures contained in such Schedules are intended only to qualify and limit the representations and warranties of the parties contained in this Agreement and shall not be deemed to expand in any way the scope of any such representation or warranty. The inclusion of any information in the Schedules shall not be deemed to be an admission or acknowledgment that such information is material or outside the ordinary course of business. The inclusion of any fact or information in a Schedule is not intended to be construed as an admission or concession as to the legal effect of any such fact or information in any proceeding between any party and any Person who is not a party.
